Description

Technical Field

[0001] This utility model relates to the field of marking and testing technology, specifically to a marking and testing device for varistors. Background Technology

[0002] As a key protective component in electronic circuits, the accuracy and readability of the marking information (such as model, parameters, batch number, etc.) on the surface of varistors directly affect product quality traceability and market compliance, and marking detection devices are usually used for testing.

[0003] However, the inspection camera in existing marking inspection devices is usually fixed to the device with bolts, which makes disassembly and maintenance time-consuming when the inspection camera is disassembled and replaced. Therefore, a marking inspection device for varistors is proposed to overcome the above problems. Utility Model Content

One end of the limiting block is inserted into the limiting hole. A sliding hole is opened on the other side of the insertion hole. A push rod is fitted in the sliding hole. The push rod corresponds to the limiting block.

[0007] Furthermore, the upper and lower sides of the sliding hole are respectively provided with sliding grooves, and the upper and lower parts of the push rod are respectively provided with sliders, which are fitted in the sliding grooves.

[0008] Furthermore, a rectangular groove is provided at the top of the inner part of the limiting hole, and the width of the rectangular groove is consistent with the width of the push rod.

[0009] Furthermore, a connecting plate is provided at one end of each of the two push rods.

[0010] Furthermore, the bottom of one end of the limiting block is designed with a sloping structure.

[0011] Furthermore, a marking machine is installed on one side of the top of the conveyor track, and the marking machine is located at the front end of the conveyor track.

[0012] Furthermore, conveyor wheels are evenly distributed on the top of the conveyor track.

[0013] Furthermore, the camera body is located at the end of the transport track.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes the plug-in connection between the plug and the socket, and the automatic locking mechanism formed by the spring and the limiting block and the limiting hole, to enable tool-free installation of the camera body.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a marking and testing device for varistors, including a conveyor track 1 and a camera body 6. A mounting bracket 4 is provided on one side of the top of the conveyor track 1, fixed to one side of the conveyor track 1 and supporting the camera body 6. A mounting plate 5 is provided on the mounting bracket 4, with two insertion holes 501 at the bottom. Two insertion blocks 601 are provided on the top of the camera body 6, inserted into the insertion holes 501. The mounting plate 5 serves as a transition structure, enabling quick camera installation through the insertion holes 501 and the insertion blocks 601. An installation hole 502 is provided on one side of the inner surface of the insertion hole 501. A spring 505 is provided inside the insertion hole 502. A limiting block 506 is provided at one end of the spring 505. The bottom of one end of the limiting block 506 is set with a bevel structure. The bevel structure of the limiting block 506 guides the insertion block 601 to be inserted smoothly. A limiting hole 602 is provided on the insertion block 601. One end of the limiting block 506 is inserted into the limiting hole 602. After the insertion block 601 is inserted into the insertion hole 501, the spring 505 pushes the limiting block 506 to lock into the limiting hole 602, forming a self-locking mechanism. A sliding hole 503 is provided on the other side of the insertion hole 501. A push rod 507 is fitted in the sliding hole 503. The push rod 507 corresponds to the limiting block 506.

[0024] The sliding hole 503 has sliding grooves 504 on its upper and lower sides. The push rod 507 has sliders 508 on its upper and lower parts, which fit into the sliding grooves 504. The limiting hole 602 has a rectangular groove 603 on its top. The width of the rectangular groove 603 is the same as the width of the push rod 507, so that the push rod 507 will not limit the insertion block 601. One end of the two push rods 507 is provided with a connecting plate 509. The connecting plate 509 integrates the two push rods 507 to achieve synchronous unlocking. Pushing the push rod 507 to slide along the sliding hole 503, the limiting block 506 is disengaged from the limiting hole 602 by the guidance of the sliders 508 and the sliding grooves 504.

[0025] By engaging the insert 601 with the socket 501, and with the spring 505 and the limiting block 506 automatically locking with the limiting hole 602, the camera body 6 can be installed without tools. The sliding design of the push rod 507 and the sliding hole 503 allows for one-handed unlocking, facilitating quick replacement or adjustment of the camera position. This solves the problem of time-consuming disassembly and maintenance when disassembling and replacing the inspection camera.

[0026] A marking machine 2 is installed on one side of the top of the conveyor track 1. The marking machine 2 is located at the front end of the conveyor track 1. Conveyor wheels 3 are evenly distributed on the top of the conveyor track 1. The conveyor track 1 serves as the transmission channel for the varistor. With the evenly distributed conveyor wheels 3, the product is moved smoothly to the marking and inspection station. The camera body 6 is located at the rear of the conveyor track 1. The marking machine 2 is located at the front end, and the camera body 6 is located at the rear end, forming a linear assembly line layout.
