Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing and processing technology, and in particular to an automatic testing machine for XLR connector locking plates. Background Technology

[0002] The XLR connector latch test is a quality inspection conducted on the connection components of audio equipment. By simulating real-world usage scenarios, multiple tests are performed on the latch using professional equipment. The insertion and removal test verifies whether the latch can maintain a secure connection and not easily fall off after multiple insertions and removals, ensuring safe use. The conductivity test checks whether the contacts maintain good conductivity after frequent use, preventing signal transmission interference and ensuring the reliable performance of the XLR connector latch.

[0003] Traditional testing relies heavily on manual operation. Testers need to manually plug and unplug the plug and determine whether the locking plate is locked. This method is not only inefficient and cannot meet the needs of large-scale production, but it is also prone to human error due to inconsistent operating force and speed, resulting in unstable test results. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an automatic testing machine for XLR connector locking plates, which aims to improve the problems of low efficiency, easy introduction of human error leading to unstable test results, and inability to meet the needs of large-scale production in traditional manual testing of XLR connector locking plates.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic testing machine for XLR lock plates, comprising a workbench, a support mechanism fixedly connected to the bottom of the workbench, a waste collection box fixedly connected to one side of the workbench, a good product guide box fixedly connected to the other side of the workbench, a mounting base fixedly connected to the top of the workbench, a first single-axis robot mounted at one end of the mounting base, a sorting mechanism fixedly connected to the output end of the first single-axis robot, a third single-axis robot mounted at the other end of the mounting base, a standard tester mounted at the output end of the third single-axis robot, a test plug fixedly provided at the output end of the standard tester, and a lock plate push handle opening device fixedly connected to one end of the top of the workbench.

[0006] By adopting the above technical solution, the product is stably fixed by the product fixing carrier and the limiting frame. The third single-axis robot drives the test plug to be coaxially aligned with the product. With the precise positioning of the limiting frame, the test conditions are consistent every time, avoiding random errors caused by manual operation. The selected standard tester realizes the objective collection and judgment of pull-out force data. Combined with the program control of the robot, good and defective products can be automatically sorted to designated areas, avoiding the problem of mixed materials from the root, effectively intercepting the outflow of defective products with locking function, and solving the problems of low efficiency, easy introduction of human error leading to unstable test results, and inability to meet the needs of large-scale production in traditional manual testing of XLR locking pins.

[0007] Preferably, the support mechanism includes a work cabinet, the bottom of which is evenly connected with support legs, and a storage slot is provided on one side of the work cabinet.

[0008] Preferably, the bottom of the workbench is fixedly connected to the top of the work cabinet.

[0009] Preferably, the sorting mechanism includes a hydraulic cylinder, the output end of which is fixedly connected to a robotic arm, and the hydraulic cylinder is installed at the output end of the first single-axis robot.

[0010] Preferably, a second single-axis robot is installed at the other end of the top of the workbench, and the output end of the second single-axis robot is fixedly connected to a product fixing carrier.

With the help of the limiting frame, the product is precisely positioned to ensure that the test conditions are consistent each time, avoiding the random errors of manual operation. The standard tester is selected to realize the objective collection and judgment of pull-out force data. Combined with the program control of the robot, good and bad products can be automatically sorted to the designated area, avoiding the problem of mixing materials from the root, effectively intercepting the outflow of defective products with locking function, and solving the problems of low efficiency, easy introduction of human error leading to unstable test results, and inability to meet the needs of large-scale production in traditional manual testing of XLR locking pins.

[0015] 2.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 - Figure 5 An embodiment of this utility model provides an automatic testing machine for XLR lock plates, including a workbench 4, a support mechanism fixedly connected to the bottom of the workbench 4, a waste collection box 5 fixedly connected to one side of the workbench 4, a good product guide box 9 fixedly connected to the other side of the workbench 4, a mounting base 20 fixedly connected to the top of the workbench 4, a first single-axis robot 6 mounted at one end of the mounting base 20, a sorting mechanism fixedly connected to the output end of the first single-axis robot 6, a third single-axis robot 19 mounted at the other end of the mounting base 20, a standard tester 10 mounted at the output end of the third single-axis robot 19, a test plug 15 fixedly provided at the output end of the standard tester 10, and a lock plate push handle opening device 16 fixedly connected to one end of the top of the workbench 4.

[0024] Specifically, the workbench 4 provides a stable working platform for the entire testing machine; the support mechanism is used to support and stabilize the workbench 4; the waste collection box 5 and the good product guide box 9 are used to collect unqualified and qualified products respectively, realizing automatic sorting; the mounting base 20 provides the mounting foundation for the first single-axis robot 6 and the third single-axis robot 19; the first single-axis robot 6 drives the sorting mechanism to move horizontally, realizing the gripping and handling of products; the third single-axis robot 19 drives the standard tester 10 to move, realizing the precise docking of the test plug 15 with the product to be tested; the locking plate push handle opening device 16 is used to automatically open the locking plate push handle on the XLR connector before testing, preparing for the insertion of the test plug 15, improving the degree of automation, and solving the problems of low efficiency, easy introduction of human error leading to unstable test results, and inability to meet the needs of large-scale production in traditional manual testing of XLR connector locking plates.

[0025] Reference Figure 1 - Figure 2 The support mechanism includes a work cabinet 2, with support legs 1 evenly connected to the bottom of the work cabinet 2. A storage slot 3 is provided on one side of the work cabinet 2. The bottom of the worktable 4 is fixedly connected to the top of the work cabinet 2. The sorting mechanism includes a hydraulic cylinder 7, with a robotic arm 8 fixedly connected to the output end of the hydraulic cylinder 7. The hydraulic cylinder 7 is installed at the output end of the first single-axis robot 6.

[0026] Specifically, in the support mechanism, the work cabinet 2 not only provides support but also storage space for storing tools and spare parts; the support legs 1 ensure the stability of the equipment on the ground; in the sorting mechanism, the first single-axis robot 6 provides horizontal movement, and the hydraulic cylinder 7 provides vertical extension and retraction power to drive the robotic arm 8 to move up and down; the robotic arm 8 is responsible for grabbing and releasing products, and after testing, the products are placed into the good product guide box 9 or the waste product collection box 5 respectively.

[0027] Reference Figure 4-5 A second single-axis robot 18 is installed at the other end of the top of the workbench 4. The output end of the second single-axis robot 18 is fixedly connected to a product fixing carrier 12. The test product 11 is fixedly installed inside the product fixing carrier 12. A control panel 13 is fixedly installed on one side of the standard tester 10. A protective cover 14 is installed on the outer wall of the test plug 15. A limit frame 17 is fixedly connected to one side of the top of the workbench 4.

[0028] Specifically, the second single-axis robot 18 moves the product fixing carrier 12 and the test product 11, accurately transporting them to the lock opening station and the testing station; the product fixing carrier 12 is used to firmly fix the test product 11, ensuring stable position during testing; the control panel 13 is used to set test parameters, start and stop, test process, and display test results; the protective cover 14 is used to protect the test plug 15, preventing it from being damaged or contaminated in non-testing states; the limit frame 17 is used to limit the movement range of the product fixing carrier 12, playing a safety protection role.

[0029] Working principle: Before the test begins, the operator fixes the XLR connector to be tested onto the product fixing carrier 12, and sets the pull-out force judgment threshold and other test parameters through the control panel 13. Then, the second single-axis robot 18 starts, moving the product fixing carrier 12 and the test product 11 on it to the working position of the locking tab push handle opening device 16. The locking tab push handle opening device 16 is activated, automatically pushing the locking tab push handle on the XLR connector to the open position, eliminating the plug insertion obstruction and ensuring that the test plug 15 can be smoothly connected. The second single-axis robot 18 then moves the test product 11 with the unlocked locking tab to the test station, where it contacts and positions itself with the limit frame 17, ensuring that the test plug... 15 is coaxially aligned with the XLR connector interface to avoid affecting the pull-out force test results due to positional deviation. At the start of the test, the third single-axis robot 19 starts, moving the standard tester 10 and test plug 15 towards the test product 11, precisely inserting the test plug 15 into the XLR connector interface. Then, the locking lever resets under the product's own structural action. The standard tester 10 starts the pull-out force test program, and the third single-axis robot 19 slowly pulls the test plug 15 outwards. The standard tester 10 monitors and records the force data during the pull-out process in real time. If the product's locking function is normal, it will automatically lock the test plug 15. At this point, the pull-out force detected by the standard tester 10 exceeds the preset value. If a product is deemed a good product by setting a threshold, the control system immediately sends a command to the locking plate push handle opening device 16. The device then opens the locking plate, releasing the locking force. The third single-axis robot 19 then smoothly pulls out and resets the test plug 15. If the product's locking plate function fails and cannot lock the test plug 15, the pulling force detected by the standard tester 10 is lower than the preset threshold, and the plug will be smoothly pulled out, resulting in a defective product. In this case, the locking plate push handle opening device 16 does not operate, and the third single-axis robot 19 directly resets the plug. Based on the judgment result, the control system sends commands to the first single-axis robot 6 and the sorting mechanism. If the product is good: the first single-axis robot 6 moves the hydraulic cylinder 7 and the robotic arm 8. The robot moves to the product fixing carrier 12, the hydraulic cylinder 7 extends, and the robot arm 8 precisely grabs the test product 11; then the first single-axis robot 6 moves to the good product guide box 9 according to the preset path, the robot arm 8 releases the product, and the product slides into the good product collection area along the guide box to complete the good product sorting. If it is a defective product: the first single-axis robot 6 drives the robot arm 8 to grab the product and move to the waste collection box 5 to release it, and put the defective product into the waste area to avoid confusion with the good products. After the robot arm 8 releases the product and resets, the second single-axis robot 18 sends the empty product fixing carrier 12 back to the loading position, and the operator can continue to place the product to be tested 11 to achieve unmanned automatic cyclic testing.
