Manufacturing method of surface defect detection device for industrial glove production line

- Nov 25, 2020-

Background technique:


In the existing industrial rubber glove production line, after the glove is formed, it enters the demolding process along the line on the hand mold. During this period, it is necessary to inspect the surface of the glove to ensure that there is no surface defect such as pinholes or breakage on the surface of the glove.


At present, the surface defects of gloves are usually detected by human eyes. Workers carefully observe the gloves on the hand mold with naked eyes on the production line to judge whether there are holes or damages. If there are defects on the surface of the gloves, there will be a surface The defective glove was peeled off the hand mold.


Manual detection of glove surface defects has the following problems: 1. The reliability is low, and the test results are obtained by human observation, so it is possible to detect very small leaks; 2. It takes labor and time, and manual inspection requires investment A large amount of labor causes a waste of human resources. At the same time, manual inspection is not efficient and takes a long time, which reduces the production efficiency of gloves and increases production costs; 3. The inspection standards are not uniform. For the same product, different inspectors There may be multiple criteria for judging, and qualified products may be eliminated or unqualified products may be mixed into qualified products; 4. There is negligence in work, and the inspectors will use the unqualified products as qualified products into the market when they are negligent. The gloves will cause unnecessary trouble when used in some special industries.

Technical realization elements:


The object of the present invention is to provide a surface defect detection device for an industrial glove production line that can replace human eyes to detect surface defects.


To achieve the above objective, the present invention adopts the following technical solutions:


The surface defect detection device of an industrial glove production line includes a shell, a detection device and a rejection device. The shell is rotatably connected with a transmission rod, and the inner wall of the shell is fixedly connected with a medium box for holding conductive media. The transmission rod A hand mold is rotatably connected, a turning driving mechanism for driving the hand mold to turn is fixed on the housing, the medium tank is connected with the hand mold through a hose, and a first valve is provided on the hose; The medium box is also connected with a turbine, the turbine of the turbine is coaxially fixedly connected with fan blades, and the fan blades are located on one side of the hand mold; the rejection device includes an electric telescopic rod and a gripper, the electric telescopic rod One end is fixed on the inner wall of the housing, the other end of the electric telescopic rod is fixedly connected with the gripper, and the gripper is located under the hand mold; under the rejecting device is provided for controlling the rejecting device communication , The trigger mechanism of the rejection device with power failure, the trigger mechanism of the rejection device includes a trigger box, the upper part of the trigger box has an opening and the opening is located directly below the hand mold, and the inner wall of the trigger box is fixedly provided with two electric retractable A conductive sheet electrically connected to the rod, the bottom of the trigger box is connected with a medium pipe, and a second valve is provided on the medium pipe; the hand mold is provided with a medium line, and a medium sensor is fixed at the medium line The media sensor is electrically connected with a timer, the timer is electrically connected with a controller, and the controller is electrically connected with the first valve and the second valve.


The working principle of this solution is:


The transmission rod is used to transfer the hand model, and the medium box is used to hold the conductive medium. During testing, the conductive medium in the medium box enters the hand model through the hose, and the controller controls the first valve on the hose to enter the hand model The conductive medium just reaches the medium line. The medium sensor at the medium line is used to detect whether there is conductive medium at the medium line. The timer is used to limit the time for the conductive medium to enter the hand mold. After the timer is completed, when the glove is damaged or needle When opening, the conductive medium in the glove will overflow from the glove through the damage or pinhole and enter the trigger box under the hand mold. When the conductive medium in the trigger box is in contact with both conductive sheets, it is equivalent to two conductive sheets. The pieces are connected by a wire, that is, the switch of the electric telescopic rod is closed, the electric telescopic rod is extended, and the gripper at one end of the electric telescopic rod is moved horizontally to just below the hand mold, and the waste gloves on the hand mold are pulled off, and then the electric telescopic rod Shorten, the gripper moves horizontally and leaves directly under the hand mold, the controller controls the second valve to close, so that the conductive medium in the medium box flows out; when the glove is intact, the conductive medium in the glove will not overflow, and the conductive medium in the glove is always with the medium. When the sensor is in contact, the sensor sends a signal to the controller. The controller controls the flip driving mechanism to drive the hand mold to rotate in the circumferential direction of the transmission rod. The conductive medium in the hand mold is poured out; at the same time, the conductive medium enters the turbine and the turbine from the medium box. Start to work, the turbine of the turbine drives the fan blades to rotate, generate airflow, and dry the conductive medium remaining in the intact gloves.


The following technical effects can be achieved by adopting this scheme:


1. Determine whether the glove is damaged or pinhole by whether the conductive medium overflows from the glove. Compared with judging whether the outer surface of the glove is damaged by the human eye, it has high reliability and high accuracy, and it is not observable to the naked eye. Holes can be easily identified through conductive media;


2. For waste gloves, it can be automatically removed after judgment, without manual removal, which greatly reduces labor intensity.
