Description

Technical Field

[0001] This utility model relates to the field of electronic component testing technology, and in particular to a pressure testing device for relay welding products. Background Technology

[0002] In the quality inspection of relay soldered products, traditional methods require separate steps for mechanical pressure testing of the solder joints and circuit continuity verification. First, specific pressure is applied to the solder joints using independent pressure equipment to detect potential issues such as poor soldering, cracks, or insufficient stress. Then, the circuit is moved to another station for continuity testing. This separate testing method has significant drawbacks: multiple clamping operations lead to positioning errors, affecting the accuracy of pressure testing and the reliability of continuity results; the process connection efficiency is low, and manual transfer can easily cause secondary damage to the product; furthermore, the dispersed equipment occupies a large space and is highly complex to operate. Especially for miniature relays, manual pressure application makes it difficult to accurately control the pressure point and consistency, easily leading to missed detections or overload damage to the solder joints due to pressure deviations. Existing technologies lack integrated devices, making it impossible to simultaneously achieve a unified testing process of precise pressure application, real-time pressure value monitoring, and automatic continuity verification at a single station, thus restricting production efficiency and product reliability. Therefore, there is an urgent need to develop an automated device that integrates clamping and positioning, pressure testing, and continuity testing functions, and coordinates the testing actions through independent transfer components, to solve the problems of inaccuracy, low efficiency, and equipment redundancy caused by separate testing. Utility Model Content

[0003] The purpose of this invention is to provide a pressure detection device for relay welding products.

[0004] The innovation of this utility model lies in the integration of an installation slot into the workbench, combined with a clamping component to fix the product, and the use of a dual-module collaborative mechanism where an independently driven first transmission component controls the pressure detection component to apply pressure precisely, and a second transmission component controls the power detection component to automatically detect electricity. This achieves seamless switching between welding point pressure testing and electrical connectivity testing, solving the problems of positioning errors, low efficiency, and secondary damage caused by separate equipment, and improving testing accuracy and reliability.

[0005] To achieve the aforementioned objectives, the technical solution of this utility model is as follows: a pressure testing device for relay welding products, comprising a workbench, a mounting slot for placing the product on the workbench, a clamping component for pressing the product to be tested into the mounting slot, a pressure testing component for measuring the pressure at the welding point of the product, and a first conveying component for moving the pressure testing component to or away from the product to be tested. The workbench also includes a current-continuity testing component for detecting whether the welding point of the product to be tested is electrically connected, and a second conveying component for moving the current-continuity testing component to or away from the product to be tested. By integrating the mounting slot, clamping component, pressure testing component, current-continuity testing component, and independent first and second conveying components into the workbench, the entire process of product clamping, pressure testing, and continuity testing can be automatically completed at a single station, eliminating positioning errors and efficiency losses caused by step-by-step operations.

[0006] Furthermore, the clamping assembly includes two symmetrically arranged clamping arms. One end of each clamping arm is a clamping part, and the other end is equipped with a first cylinder assembly for raising or lowering the clamping arm. The clamping parts of the two clamping arms are arranged facing each other. By using symmetrically arranged clamping arms and a first cylinder drive, the clamping force is evenly distributed and adjustable, avoiding single-point pressure loss.

[0007] Furthermore, the bottom of the clamping part is provided with an anti-slip textured layer or an elastic pad layer. By adding an anti-slip textured layer or an elastic pad layer to the clamping part, the product surface is protected from scratches and friction is increased, preventing displacement during testing and improving positioning stability.

[0008] Furthermore, the first conveying component includes two vertical rails arranged parallel to each other and perpendicular to the worktable. At the top of each rail are a vertically arranged second cylinder assembly and a mounting base for fixing the second cylinder assembly. A movable base, capable of reciprocating up and down along the vertical rails, is slidably connected to each rail. The piston rod end of the second cylinder assembly faces downwards and is fixedly connected to the movable base. The pressure detection component is fixed to the movable base. The combination of the vertical rails and the second cylinder assembly drives the movable base, enabling the pressure detection component to move precisely vertically, ensuring that the pressure sensor aligns with the welding point.

[0009] Furthermore, the pressure detection assembly includes a pressure sensor and several pressure detection heads connected to the bottom of the pressure sensor. By configuring multiple pressure detection heads, the pressure values ​​at different solder points of the relay can be detected simultaneously, improving test coverage.

[0010] Furthermore, the pressure testing head includes a first testing head for testing the copper sheets of the relay, a second testing head for testing the copper strips on the product, and a third testing head for testing the current transformer. By subdividing the testing targets of the first, second, and third testing heads, the structural differences of the copper sheets, copper strips, and current transformers can be specifically adapted to avoid interference between the testing heads.

[0011] Furthermore, the first and second detection heads are located at the bottom of the same movable base, while the third detection head is located at the bottom of another movable base. By placing the first, second, and third detection heads on different movable bases, the multiple detection heads can be controlled independently, avoiding interference between detection areas.

[0012] Furthermore, the bottom of the mounting slot has a through hole communicating with the bottom of the workbench. The second conveying assembly includes a vertically arranged third cylinder assembly and a mounting base located at the bottom of the workbench for fixing the third cylinder assembly. The piston rod end of the third cylinder assembly faces upward, and a lifting block is fixedly connected to the end of the piston rod. The power-on detection assembly is fixed to the lifting block. By providing a through hole at the bottom of the mounting slot and using the third cylinder assembly to drive the lifting block, the power-on detection assembly can directly contact the solder joint from below the product, saving workbench space.

[0013] Furthermore, the power-on detection assembly includes an insulating block positioned above the lifting block and several vertically arranged power-on detection heads positioned on top of the insulating block. By fixing the power-on detection heads to the top of the insulating block, current interference is isolated during the detection process, ensuring the accuracy of the continuity test and operational safety.

[0014] Furthermore, the first cylinder assembly is a rotary clamping cylinder. By using a rotary clamping cylinder to drive the clamping arm, the clamping part can be quickly lifted away from the product, reducing non-inspection time and improving equipment efficiency.

[0015] The beneficial effects of this utility model are as follows: by integrating the mounting slot into the workbench and fixing the product with the clamping component, and adopting a dual-module collaborative mechanism of independently driven No. 1 transmission component controlling the pressure detection component to accurately apply pressure and No. 2 transmission component controlling the power detection component to automatically detect electricity, seamless switching between welding point pressure testing and electrical connectivity testing is achieved, completely solving the problems of positioning error, low efficiency and secondary damage caused by separate equipment, and improving testing accuracy and reliability.

The workbench 1 also has an electrical connection detection assembly 7 for detecting whether the welding point of the product under test is electrically connected, and a second transmission assembly 6 for moving the electrical connection detection assembly 7 to or away from the product under test. The clamping assembly 3 includes two symmetrically arranged clamping arms 3.1. One end of each clamping arm 3.1 is a clamping part 3.11, and the other end has a first cylinder assembly 3.2 for raising or lowering the clamping arm 3.1. The clamping parts 3.11 of the two clamping arms 3.1 are arranged facing each other. The bottom of the clamping part 3.11 is provided with an anti-slip textured layer 3.111 or an elastic pad layer 3.112. The first conveying assembly 5 includes two vertical rails 5.1 arranged parallel to each other and perpendicular to the worktable 1. At the top of each of the two vertical rails 5.1, a second cylinder assembly 5.2 and a fixing seat 5.3 for fixing the second cylinder assembly 5.2 are respectively mounted vertically. A movable seat 5.4, capable of reciprocating up and down along the vertical rails 5.1, is slidably connected to the vertical rails 5.1. The piston rod end of the second cylinder assembly 5.2 faces downwards and is fixedly connected to the movable seat 5.4. The pressure detection assembly 4 is fixed to the movable seat 5.4. The pressure detection assembly 4 includes a pressure sensor 4.1 and several pressure detection heads 4.2 connected to the bottom of the pressure sensor 4.1. The pressure detection heads 4.2 include a first detection head 4.21 for detecting relay copper sheets, a second detection head 4.22 for detecting copper strips on the product, and a third detection head 4.33 for detecting current transformers. The first detection head 4.21 and the second detection head 4.22 are located at the bottom of the same movable seat 5.4, and the third detection head 4.23 is located at the bottom of another movable seat 5.4. The bottom of the mounting slot 2 has a through hole 2.1 communicating with the bottom of the worktable 1. The second conveying assembly 6 includes a vertically arranged third cylinder assembly 6.1 and a mounting seat 6.2 located at the bottom of the worktable 1 for fixing the third cylinder assembly 6.1. The piston rod end of the third cylinder assembly 6.1 faces upwards, and a lifting block 6.3 is fixedly connected to the end of the piston rod. The power-on detection assembly 7 is fixed to the lifting block 6.3. The power-on detection assembly 7 includes an insulating block 7.1 located above the lifting block and several vertically arranged power-on detection heads 7.2 located on top of the insulating block 7.1. The first cylinder assembly 3.2 is a rotary clamping cylinder.

[0023] The working principle of this utility model is as follows: First, the relay product is placed in the mounting slot 2 of the workbench, and the first cylinder assembly 3.2 is activated to drive the two symmetrical clamping arms 3.1 to press down. The anti-slip textured layer 3.111 or elastic pad layer 3.112 at the bottom of the clamping part 3.11 contacts the product surface, and rapid and uniform clamping is achieved by rotating the clamping cylinder to prevent the product from shifting during testing. Second, the first conveying assembly 5 is activated: the second cylinder assembly 5.2 pushes the moving seat 5.4 to descend vertically along the vertical track 5.1, driving the pressure detection assembly 4 to move down. The first detection head 4.21, the second detection head 4.22, and the third detection head 4.23 at the bottom of the pressure sensor 4.1 accurately contact the corresponding welding points of the product. The first, second, and third detection heads belong to different moving seats 5.4, apply pressure independently, and the pressure value at each welding point is fed back in real time by the pressure sensor 4.1. After the pressure test is completed, the second conveying assembly 6 is activated: the third cylinder assembly 6.1 at the bottom of the mounting slot 2 pushes the lifting block 6.3 upward, allowing the current-conducting detection head 7.2 on top of the insulating block 7.1 to pass through the through hole 2.1 and contact the corresponding solder joint on the product, detecting the current to verify electrical continuity; the pressure test and the current-conducting test can also be performed simultaneously. Finally, each cylinder assembly is reset in sequence: the second cylinder assembly 5.2 lifts the pressure detection assembly 4, the third cylinder assembly 6.1 drives the current-conducting detection assembly downward, and the rotating clamping cylinder lifts the clamping arm 3.1. After the product is removed, the device returns to its initial state and enters the next testing cycle.
