Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, specifically the TSH52 kit testing equipment. Background Technology
[0002] With the increasing integration of electronic components and the widespread use of complex circuits, the problems of low efficiency and high missed detection rate of traditional manual testing have become prominent, giving rise to high-precision automated testing technology. The TSH52 is based on Teradyne's multi-site online testing platform and adopts a zero-occupancy test head design, which can be integrated into automated production lines and improve efficiency through parallel testing technology.
[0003] During testing, dust, metal shavings, or oil can adhere to the probe or contacts, forming an insulating or interference layer. This can increase the contact resistance between the probe and the circuit board pads. Conductive particles in the dust may fall into the circuit board inside the probe, causing short circuits or component burnout. Furthermore, if the probe is not cleaned for a long time, it may eventually be forced to shut down for disassembly and repair due to severe contamination, reducing work efficiency. Therefore, we proposed the TSH52 kit testing equipment. Utility Model Content
[0004] The purpose of this invention is to provide a TSH52 kit testing device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a TSH52 kit testing device, including a workbench, and further comprising:

[0008] Furthermore, a testing assembly is provided on the top of the workbench. The testing assembly includes a bracket, an electric push rod is provided on the top of the bracket, a connecting plate is connected to the output end of the electric push rod, and a probe is provided at the bottom of the connecting plate.
[0009] The above technical solution involves setting up test components and using a probe to perform contact detection with the circuit board.
[0010] Furthermore, a column is provided on the top of the workbench near the connecting plate, and the connecting plate is slidably connected to the column.
[0011] The above technical solution is adopted: by setting up columns, the movement of the connecting plate is limited to prevent swaying and deviation during descent.
[0012] Furthermore, a limiting component is provided on the baffle, the limiting component includes an extension plate, a groove is provided on the top of the workbench near the extension plate, a limiting block is slidably connected in the groove, and the extension plate is connected to the limiting block.
[0013] The above technical solution is adopted: by setting a limit component, the movement trajectory of the baffle is limited to prevent deviation.
[0014] Furthermore, a spring-loaded assembly is provided on the top of the extension plate, the spring-loaded assembly includes a fixed plate, a support plate is provided on the top of the worktable, and a spring connects the fixed plate and the support plate.
[0015] The above technical solution is adopted: by setting a rebound component, when the first motor rotates in the opposite direction, the baffle can automatically spring back to its original position by the elastic force after the spring contracts.
[0016] Furthermore, a clamping assembly is provided on the top of the baffle. The clamping assembly includes a slide rail, a lead screw is rotatably connected inside the slide rail, a slider is threaded onto the lead screw, and a clamping plate is connected to the slider.

There are two sliders, and the two sliders are threadedly connected to the lead screw in opposite directions.
[0019] The above technical solution involves setting a second motor as the power source for the rotation of the lead screw.
[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0021] In this invention, by setting up a cleaning component to clean the probe and contacts, interference layers such as dust and oil can be eliminated, and contact resistance can be reduced. The design of the opening and closing component can store and shield the slot and cleaning component during the testing process. This solves the problem that during the testing process, dust, metal debris or oil will adhere to the probe or contacts, forming an insulating layer or interference layer, which will increase the contact resistance between the probe and the circuit board pads. Conductive particles in the dust may fall into the circuit board inside the probe, causing short circuits or component burnout. Furthermore, if the probe is not cleaned for a long time, it may eventually be forced to stop for disassembly and repair due to serious contamination, reducing work efficiency.

[0035] 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.
[0036] like Figures 1-5 As shown, this utility model provides a technical solution: a TSH52 kit testing device, including a workbench 1, and further comprising:
[0037] Cleaning component 3 includes a slot 31 on the top of the workbench 1, and a cleaning cylinder 32 is disposed in the slot 31.
[0038] The opening and closing assembly 4 includes a baffle 41 set on the top of the workbench 1, a buckle 42 connected to the baffle 41, a connecting rope 43 connected to the buckle 42, a connecting seat 45 set on the side of the workbench 1 near the connecting rope 43, a take-up roller 44 rotatably connected to the connecting seat 45, the end of the connecting rope 43 away from the buckle 42 is sleeved on the take-up roller 44, a first housing 46 is set on the connecting seat 45, a first motor is set inside the first housing 46, and the take-up roller 44 is connected to the output end of the first motor;
[0039] The top of the workbench 1 is equipped with a test component 2, which includes a bracket 21. The top of the bracket 21 is equipped with an electric push rod 22. The output end of the electric push rod 22 is connected to a connecting plate 23. The bottom of the connecting plate 23 is equipped with a probe 24.
[0040] Specifically, the first motor is turned on to drive the take-up roller 44 to rotate on the connecting seat 45. The take-up roller 44 drives the connecting rope 43 to take up the rope. During the take-up process, the buckle 42 and the baffle 41 move, thereby exposing the slot 31. Then, the electric push rod 22 is turned on to drive the connecting plate 23 to descend, thereby driving the probe 24 at the bottom of the connecting plate 23 to descend and insert into the cleaning cylinder 32 for cleaning.
[0041] Furthermore, such as Figure 1 As shown: A column is provided on the top of the workbench 1 near the connecting plate 23. The connecting plate 23 is slidably connected to the column. When the connecting plate 23 moves, it will slide synchronously on the column, thereby limiting the position of the connecting plate 23.
[0042] The above solutions also have the problem that the baffle 41 may be pulled off its original trajectory by the connecting rope 43 during movement, such as... Figure 2 and Figure 3 As shown: A limiting component 5 is provided on the baffle 41. The limiting component 5 includes an extension plate 51. A slide groove 52 is provided on the top of the worktable 1 near the extension plate 51. A limiting block is slidably connected in the slide groove 52. The extension plate 51 is connected to the limiting block. When the baffle 41 moves, it will drive the extension plates 51 on both sides to move synchronously. The extension plate 51 drives the limiting block at the bottom to slide in the slide groove 52, thereby limiting the baffle 41.
[0043] The above solution also has the problem that the baffle 41 cannot automatically spring back to its original position, such as... Figure 2As shown: The top of the extension plate 51 is provided with a spring-loaded assembly 6, which includes a fixed plate 61 and a support plate 63 on the top of the worktable 1. A spring 62 is connected between the fixed plate 61 and the support plate 63. When the first motor rotates in the opposite direction, the baffle 41 can automatically spring back to its original position by the elastic force of the spring 62 after it contracts.
[0044] Furthermore, such as Figure 2 As shown: A clamping assembly 7 is provided on the top of the baffle 41. The clamping assembly 7 includes a slide rail 71, a lead screw 72 is rotatably connected inside the slide rail 71, a slider 73 is threadedly connected to the lead screw 72, a clamping plate 74 is connected to the slider 73, a second housing 75 is provided on the slide rail 71, a second motor is provided inside the second housing 75, the lead screw 72 is connected to the output end of the second motor, there are two sliders 73, the two sliders 73 are threaded on the lead screw 72 in opposite directions, when the second motor is turned on, the lead screw 72 is driven to rotate inside the slide rail 71, the lead screw 72 drives the slider 73 to slide inside the slide rail 71, thereby driving the clamping plate 74 to clamp and limit the circuit boards of different sizes.
[0045] The working principle provided by this utility model is as follows: Figures 1-5 As shown: First, the circuit board is placed on top of the baffle 41. Then, the second motor is turned on to drive the lead screw 72 to rotate within the slide rail 71. The lead screw 72 drives the slider 73 to slide within the slide rail 71, thereby causing the clamping plate 74 to clamp and limit the circuit boards of different sizes. The electric push rod 22 is turned on to drive the connecting plate 23 to descend, thereby causing the probe 24 at the bottom of the connecting plate 23 to descend and inspect the circuit board. When dust or powder accumulates on the probe 24, the first motor is turned on to drive the take-up roller 44 to rotate on the connecting seat 45. The take-up roller 44 drives the connecting rope 4 3. During the winding process, the buckle 42 and the baffle 41 move. During the movement of the baffle 41, the extension plates 51 on both sides move synchronously. The extension plates 51 drive the bottom limiting block to slide in the slide groove 52, thereby limiting the baffle 41 and exposing the slot 31. Then, the electric push rod 22 is activated to drive the connecting plate 23 to descend, thereby driving the probe 24 at the bottom of the connecting plate 23 to descend and insert into the cleaning cylinder 32 for cleaning. When the first motor rotates in the reverse direction, the baffle 41 can automatically spring back to its original position by the elastic force of the spring 62 after it is contracted.
[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced.
