Description

Technical Field

[0001] This utility model relates to the technical field of board end testing, and in particular to a drawer-type board testing module. Background Technology

[0002] Board-end testing is a crucial step in verifying the functionality and performance of circuit boards. In the manufacturing process of electronic products, accurate and efficient board-end testing plays a vital role in ensuring product quality and improving production efficiency. Board testing modules are the core equipment for performing board-end testing.

[0003] Currently, traditional board testing modules mostly adopt a fixed structure. When changing fixtures or debugging equipment, it is necessary to frequently disassemble the module shell, or even remove the entire module from the test cabinet. The operation is cumbersome and time-consuming. Therefore, a drawer-type structure is adopted to achieve quick replacement of fixtures and debugging equipment. However, the existing drawer-type structure still has shortcomings in stability and space utilization. Some designs are prone to shaking when the tray is fully pulled out, which affects the test accuracy. Moreover, the space layout is not reasonable enough, which restricts the placement of fixtures and DUTs. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, this utility model provides a drawer-type plate testing module. Through the setting of the pull-out mechanism, the tray can be fully extended out of the test cabinet, which is convenient for changing fixtures and DUTs. The tray adopts a layered design, which optimizes the space utilization and makes the layout of fixtures and DUTs more flexible during the test. At the same time, through the setting of the sliding plate, the ball bearings inside the slide rail can maintain a relatively stable arrangement during the sliding process. The ball bearings will not affect the smoothness of the slide rail within the slide rail due to collision or positional displacement, which improves the stability of the tray pull-out and ensures that the tray will not shake during the test, thereby ensuring the test accuracy.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a drawer-type plate measuring module, comprising: a plate measuring module and a pull-out mechanism. The pull-out mechanism is disposed inside the plate measuring module and includes a mounting plate, a first slide rail, a first ball bearing, a second slide rail, a second ball bearing, a third slide rail, a tray, a pull rod, a partition, and a limiting member. The mounting plate is disposed inside the plate measuring module, and a through hole is formed on the outer wall of the mounting plate. The first slide rail is disposed on the mounting plate, the first ball bearing is disposed inside the first slide rail, the second slide rail is disposed inside the first slide rail, the second ball bearing is disposed inside the second slide rail, the third slide rail is disposed inside the second slide rail, the tray is disposed on the outer wall of the third slide rail, the pull rod is disposed on the outer wall of the tray, the partition is disposed on the inner wall of the tray, and the limiting member is disposed on the outer wall of the first slide rail.

[0007] In addition, the drawer-type plate measuring module proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the limiting component includes a first limiting block, a second limiting block, a third limiting block, and a fourth limiting block. The first limiting block is located at one end of the first slide rail, the second limiting block is located at one end of the second slide rail, the third limiting block is located at the other end of the second slide rail, and the fourth limiting block is located at one end of the third slide rail.

[0009] Specifically, the board test module is equipped with a heat dissipation component, which includes a heat spreader, a heat conduction plate, and a cooling fan. The heat spreader is located on the inner wall of the board test module, the heat conduction plate is located on the heat spreader, heat dissipation holes are opened on the outer wall of the board test module, and the cooling fan is located on the inner wall of the board test module.

[0010] Specifically, a first sliding plate is provided on the outer wall of the first ball, and a second sliding plate is provided on the outer wall of the second ball.

[0011] Specifically, a first fixing screw is provided on the heat spreader plate, and the first fixing screw passes through the heat spreader plate and is connected to the plate side module.

[0012] Specifically, a second fixing screw is provided on the outer wall of the cooling fan, and the second fixing screw passes through the cooling fan and is connected to the board side module.

[0013] Compared with existing technologies, the drawer-type plate testing module of this utility model allows the tray to fully extend out of the test cabinet through the pull-out mechanism, facilitating the replacement of fixtures and DUTs. The tray's layered design optimizes space utilization, making the layout of fixtures and DUTs more flexible during testing. Furthermore, the sliding plate ensures that the balls inside the slide rail maintain a relatively stable arrangement during sliding, preventing collisions or positional shifts that could affect the smoothness of the slide rail. This improves the stability of the tray pull-out, ensuring that the tray does not wobble during testing and thus guaranteeing testing accuracy.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] A drawer-type plate measuring module according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0025] like Figures 1-6 As shown, an embodiment of the present invention provides a drawer-type plate testing module, comprising: a plate testing module 1 and a pull-out mechanism 2.

[0026] The extraction mechanism 2 is located inside the plate measuring module 1. The extraction mechanism 2 includes a mounting plate 21, a first slide rail 23, a first ball bearing 24, a second slide rail 26, a second ball bearing 27, a third slide rail 29, a tray 210, a pull rod 211, a partition 212, and a limiting member 3.

[0027] Mounting plate 21 is installed inside plate-side module 1. Through hole 22 is provided on the outer wall of mounting plate 21. First slide rail 23 is installed on mounting plate 21. First ball bearing 24 is installed inside first slide rail 23. Second slide rail 26 is installed inside first slide rail 23. Second ball bearing 27 is installed inside second slide rail 26. Third slide rail 29 is installed inside second slide rail 26. Tray 210 is installed on the outer wall of third slide rail 29. Pull rod 211 is installed on the outer wall of tray 210. Partition 212 is installed on the inner wall of tray 210. Limiting member 3 is installed on the outer wall of first slide rail 23.

[0028] The limiting component 3 includes a first limiting block 31, a second limiting block 32, a third limiting block 33, and a fourth limiting block 34.

[0029] The first limiting block 31 is located at one end of the first slide rail 23, the second limiting block 32 is located at one end of the second slide rail 26, the third limiting block 33 is located at the other end of the second slide rail 26, and the fourth limiting block 34 is located at one end of the third slide rail 29.

[0030] Specifically, when installing the extraction mechanism 2, first insert the screws through the corresponding through holes 22 on the mounting plate 21, and then fix the mounting plate 21 firmly inside the plate module 1 by rotating the screws, ensuring that the mounting plate 21 fits tightly against the inner wall of the plate module 1 without any loosening, and the installation is complete.

[0031] When it is necessary to disassemble and maintain the extraction mechanism 2, the screws on the mounting plate 21 can be rotated in the opposite direction to remove the screws from the through hole 22. At this time, the connection between the mounting plate 21 and the inner wall of the plate-side module 1 is released, and the operator can easily remove the mounting plate 21 together with the extraction mechanism 2 from the inside of the plate-side module 1, thus completing the disassembly of the extraction mechanism 2 and facilitating subsequent maintenance work.

[0032] After the extraction mechanism 2 is installed inside the plate measuring module 1, during use, the operator can pull the lever 211. The lever 211 drives the tray 210 to slide outward along the path of the third slide rail 29, the second slide rail 26, and the first slide rail 23. During sliding, the third slide rail 29 slides within the second slide rail 26, and the second slide rail 26 slides within the first slide rail 23. During this sliding process, because the first ball bearing 24 is located between the first slide rail 23 and the second slide rail 26, when the second slide rail 26 slides within the first slide rail 23, the first ball bearing 24 rolls accordingly, effectively reducing the friction between the second slide rail 26 and the first slide rail 23, making the sliding of the second slide rail 26 smoother. Similarly, the second ball bearing 27 is located between the second slide rail 26 and the third slide rail 29. When the third slide rail 29 slides within the second slide rail 26, the second ball bearing 27 rolls accordingly, effectively reducing the friction between the third slide rail 29 and the second slide rail 26, making the sliding of the third slide rail 29 smoother. This allows the operator to easily slide the tray 210 outward or retract it inward when pulling the lever 211, improving ease of use.

[0033] In addition, a partition 212 is provided in the middle of the tray 210, dividing the tray 210 into two layers. The upper layer carries the test fixture pin plate, and the lower layer carries the fixture tray 210 and the DUT. This layered design not only optimizes space utilization but also allows for flexible adjustment of the fixture and DUT layout according to actual testing needs, improving the flexibility and efficiency of testing.

[0034] Since the first limiting block 31 is located at one end of the first slide rail 23 and the third limiting block 33 is located at one end of the second slide rail 26, when the second slide rail 26 slides to both ends of the first slide rail 23, the internal first ball bearing 24 and the second slide rail 26 will be blocked by the first limiting block 31 and the third limiting block 33, preventing them from sliding out of the first slide rail 23. Similarly, the second limiting block 32 is located at the other end of the second slide rail 26 and the fourth limiting block 34 is located at one end of the third slide rail 29. Therefore, when the third slide rail 29 slides to both ends of the second slide rail 26, the internal second ball bearing 27 and the third slide rail 29 will be blocked by the second limiting block 32 and the fourth limiting block 34, preventing them from sliding out of the second slide rail 26. This limiting design ensures the stability of the extraction mechanism 2 during the sliding process and avoids the tray shaking or falling off due to sliding between the slide rails.

[0035] In one embodiment of this application, such as Figure 4 As shown, the heat dissipation component 4 is installed inside the board test module 1.

[0036] The heat dissipation component 4 includes a heat spreader 41, a heat conduction plate 43, and a cooling fan 45.

[0037] A heat spreader 41 is disposed on the inner wall of the plate-side module 1, a heat conduction plate 43 is disposed on the heat spreader 41, a heat dissipation hole 44 is provided on the outer wall of the plate-side module 1, and a cooling fan 45 is disposed on the inner wall of the plate-side module 1.

[0038] It should be noted that the heat spreader 41 described in this embodiment adopts VC heat spreader 41 technology, which has efficient heat conduction performance and can quickly conduct the heat generated inside the plate module 1 to the entire surface of the heat spreader 41 to achieve uniform heat distribution. The heat conduction plate 43 is made of a metal material with high thermal conductivity, such as copper or aluminum, and its function is to efficiently conduct the heat generated by the electrical components inside the plate module 1 to the heat spreader 41.

[0039] Specifically, when the internal electrical components of the board-side module 1 begin to operate, they generate a large amount of heat. Since the internal electrical components are in close contact with the heat-conducting plate 43, this heat is first absorbed by the heat-conducting plate 43. The heat-conducting plate 43 is made of a metal with high thermal conductivity and is in close contact with the heat spreader 41, allowing the heat-conducting plate 43 to quickly conduct heat to the heat spreader 41. The heat spreader 41, through VC heat spreader technology, evenly distributes heat across the entire surface, preventing localized high temperatures. Since the heat spreader 41 is in close contact with the outer shell of the board-side module 1, the heat inside the heat spreader 41 is naturally dissipated to the outside through the outer shell of the board-side module 1. Simultaneously, the ventilation holes 44 on the outer wall of the board-side module 1 create air convection, further accelerating heat dissipation. The cooling fan 45 further enhances the heat dissipation effect. After the cooling fan 45 is started, it can accelerate the air flow inside the board test module 1, quickly exhaust the hot air inside through the heat dissipation hole 44, and introduce external cold air at the same time to form an effective air circulation, thereby ensuring that the internal temperature of the board test module 1 is kept within a reasonable range and avoiding the impact of overheating on the test accuracy and equipment life.

[0040] In one embodiment of this application, such as Figure 2 As shown, a first sliding plate 25 is provided on the outer wall of the first ball 24, and a second sliding plate 28 is provided on the outer wall of the second ball 27.

[0041] It is understandable that the arrangement of the first sliding plate 25 enables the multiple first balls 24 inside to maintain a relatively stable arrangement during the sliding process, and the smooth sliding of the second slide rail 26 within the first slide rail 23 will not be affected by the collision or positional shift of the first balls 24. Similarly, the arrangement of the second sliding plate 28 enables the multiple second balls 27 inside to maintain a relatively stable arrangement during the sliding process, and the smooth sliding of the third slide rail 29 within the second slide rail 26 will not be affected by the collision or positional shift of the second balls 27.

[0042] In one embodiment of this application, such as Figure 4As shown, a first fixing screw 42 is provided on the heat spreader 41, and the first fixing screw 42 passes through the heat spreader 41 and is connected to the plate side module 1.

[0043] It is understandable that by setting the first fixing screw 42, the heat dissipation plate 41 can be firmly fixed to the inner wall of the plate module 1, preventing the heat dissipation plate 41 from loosening or shifting during operation, thereby ensuring the stability and reliability of the heat dissipation component 4.

[0044] When installing the heat spreader 41, the operator first places the heat spreader 41 in the designated position on the inner wall of the plate-mounted module 1, ensuring that the heat spreader 41 is in close contact with the inner wall of the plate-mounted module 1. Then, the first fixing screw 42 is passed through the fixing hole on the heat spreader 41 and rotated into the corresponding screw hole on the inner wall of the plate-mounted module 1. By appropriately tightening the first fixing screw 42, a stable connection is formed between the heat spreader 41 and the inner wall of the plate-mounted module 1, while avoiding deformation of the heat spreader 41 due to over-tightening.

[0045] When disassembling the heat spreader 41, the operator must first use a suitable tool to rotate the first fixing screw 42 in the opposite direction, slowly unscrewing it from the screw hole on the inner wall of the platen module 1. During this process, care must be taken to control the rotation force to avoid stripping the first fixing screw 42 or damaging the screw hole on the inner wall of the platen module 1 due to excessive force. Once the first fixing screw 42 is completely removed, the connection between the heat spreader 41 and the inner wall of the platen module 1 is severed. At this point, the operator can carefully remove the heat spreader 41 from the designated position on the inner wall of the platen module 1, completing the disassembly of the heat spreader 41 for subsequent maintenance or replacement of the heat dissipation assembly 4.

[0046] In one embodiment of this application, such as Figure 4 As shown, a second fixing screw 46 is provided on the outer wall of the cooling fan 45, and the second fixing screw 46 passes through the cooling fan 45 and is connected to the board side module 1.

[0047] Understandably, by setting the second fixing screw 46, the cooling fan 45 can be firmly fixed to the inner wall of the board test module 1, preventing the cooling fan 45 from loosening or shifting due to vibration during operation, ensuring that the cooling fan 45 can operate continuously and stably, and providing reliable heat dissipation for the board test module 1.

[0048] When installing the cooling fan 45, the operator must first place the cooling fan 45 in the preset installation position on the inner wall of the board module 1, so that the air outlet of the cooling fan 45 corresponds to the heat dissipation hole 44 on the outer wall of the board module 1, to ensure that the airflow blown out by the cooling fan 45 can be smoothly discharged to the external environment through the heat dissipation hole 44. Then, the second fixing screw 46 is passed through the mounting hole on the housing of the cooling fan 45 and rotated into the corresponding screw hole on the inner wall of the board module 1. By appropriately tightening the second fixing screw 46, a stable connection is formed between the cooling fan 45 and the inner wall of the board module 1.

[0049] Working principle: When installing the extraction mechanism 2, first insert the screw through the corresponding through hole 22 on the mounting plate 21, and then fix the mounting plate 21 firmly inside the plate measuring module 1 by rotating the screw. Ensure that the mounting plate 21 is tightly attached to the inner wall of the plate measuring module 1 without any looseness, and the installation is complete.

[0050] When it is necessary to disassemble and maintain the extraction mechanism 2, the screws on the mounting plate 21 can be rotated in the opposite direction to remove the screws from the through hole 22. At this time, the connection between the mounting plate 21 and the inner wall of the plate-side module 1 is released, and the operator can easily remove the mounting plate 21 together with the extraction mechanism 2 from the inside of the plate-side module 1, thus completing the disassembly of the extraction mechanism 2 and facilitating subsequent maintenance work.

[0051] After the extraction mechanism 2 is installed inside the plate measuring module 1, during use, the operator can pull the lever 211. The lever 211 drives the tray 210 to slide outward along the path of the third slide rail 29, the second slide rail 26, and the first slide rail 23. During sliding, the third slide rail 29 slides within the second slide rail 26, and the second slide rail 26 slides within the first slide rail 23. During the sliding process, since the first ball bearing 24 is located between the first slide rail 23 and the second slide rail 26, the first ball bearing 24 will roll along with the second slide rail 26 as it slides within the first slide rail 23. This effectively reduces the friction between the second slide rail 26 and the first slide rail 23, making the sliding of the second slide rail 26 smoother. The second ball bearing 27 is located between the second slide rail 26 and the third slide rail 29. When the third slide rail 29 slides inside the second slide rail 26, the second ball bearing 27 will roll accordingly, effectively reducing the friction between the third slide rail 29 and the second slide rail 26, making the sliding of the third slide rail 29 smoother. In this way, when the operator pulls the lever 211, the tray 210 can be slid outward or retracted inward more easily, improving the convenience of use.

[0052] In addition, a partition 212 is provided in the middle of the tray 210, dividing the tray 210 into two layers. The upper layer carries the test fixture pin plate, and the lower layer carries the fixture tray 210 and the DUT. This layered design not only optimizes space utilization but also allows for flexible adjustment of the fixture and DUT layout according to actual testing needs, improving the flexibility and efficiency of testing.

[0053] The limiting components 3 are configured such that the first limiting block 31 is located at one end of the first slide rail 23, and the third limiting block 33 is located at one end of the second slide rail 26. Therefore, when the second slide rail 26 slides to both ends of the first slide rail 23, the internal first ball bearing 24 and the second slide rail 26 will be blocked by the first limiting block 31 and the third limiting block 33, preventing them from sliding out of the first slide rail 23. Similarly, the second limiting block 32 is located at the other end of the second slide rail 26, and the fourth limiting block 34 is located at one end of the third slide rail 29. Therefore, when the third slide rail 29 slides to both ends of the second slide rail 26, the internal second ball bearing 27 and the third slide rail 29 will be blocked by the second limiting block 32 and the fourth limiting block 34, preventing them from sliding out of the second slide rail 26. This limiting design ensures the stability of the extraction mechanism 2 during the sliding process and avoids equipment damage or operational inconvenience caused by sliding out.

[0054] Furthermore, through the arrangement of the heat dissipation component 4, when the internal electrical components of the board module 1 start working, a large amount of heat will be generated. Since the internal electrical components are in close contact with the heat conduction plate 43, this heat is first absorbed by the heat conduction plate 43. The heat conduction plate 43 is made of a metal material with a high thermal conductivity and is in close contact with the heat spreader 41, so that the heat conduction plate 43 can quickly conduct heat to the heat spreader 41. The heat spreader 41 distributes heat evenly across the entire surface through the VC heat spreader 41 technology, avoiding the occurrence of local high temperatures. The heat spreader 41 is in close contact with the outer shell of the board module 1, so the heat inside the heat spreader 41 will be naturally dissipated to the outside through the outer shell of the board module 1. At the same time, the heat dissipation holes 44 opened on the outer wall of the board module 1 can form air convection, further accelerating the dissipation of heat.

[0055] When the internal temperature of the board module 1 reaches a preset threshold, the cooling fan 45 will automatically start. The powerful airflow generated by the cooling fan 45 can quickly blow the heat accumulated inside the board module 1 out to the external environment through the heat dissipation holes 44, greatly improving the heat dissipation efficiency.

[0056] When the internal temperature of the board module 1 drops below the preset threshold, the cooling fan 45 will automatically stop working, thereby achieving intelligent heat dissipation control.

[0057] In summary, the drawer-type plate testing module of this utility model, through the setting of the extraction mechanism 2, allows the tray 210 to be fully extended out of the test cabinet, facilitating the replacement of fixtures and DUTs. Furthermore, the tray 210 adopts a layered design, optimizing space utilization and making the layout of fixtures and DUTs more flexible during testing. At the same time, through the setting of the sliding plate, the balls inside the slide rail can maintain a relatively stable arrangement during the sliding process, preventing the smoothness of the slide rail from being affected by collisions or positional shifts of the balls. This improves the stability of tray extraction, ensuring that the tray does not wobble during testing, thereby guaranteeing test accuracy.
