Description
Technical Field
[0001] This utility model relates to the field of copper plate processing and testing technology, specifically to a fixture for processing and testing thermally conductive copper plates. Background Technology
[0002] Thermally conductive copper plates are thermally conductive materials made of high-purity copper, characterized by high thermal conductivity, good machinability, corrosion resistance, and high-temperature resistance. They are widely used in heat dissipation systems in electronic devices, automotive electronics, and industrial control to ensure the stability and reliability of equipment under high loads. With technological advancements, the performance requirements for thermally conductive copper plates are becoming increasingly stringent, necessitating precise processing and testing. Traditional processing and testing methods for thermally conductive copper plates have shortcomings, such as cumbersome procedures and low efficiency. To address these issues, specialized processing and testing fixtures for thermally conductive copper plates have been developed to improve testing efficiency and accuracy.
[0003] Thermally conductive copper plate processing and testing fixtures play a crucial role in the processing and testing of thermally conductive copper plates. They improve testing efficiency, ensure testing accuracy, enhance product quality, and reduce costs. However, with typical thermally conductive copper plate processing and testing fixtures, after testing, it is necessary to wait for the copper plates to cool down before removing them for the next batch of copper plates. If they are removed manually without waiting, even if workers wear gloves and protective gear, there is a risk of burns and electric shock. Removing them one by one with tools is too cumbersome.

Detailed Implementation
[0023] 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.
[0024] Please see Figure 1-8 This utility model provides a fixture for testing and processing thermally conductive copper plates:
[0025] See Figure 1 , Figure 3 , Figure 4As shown, a fixture for processing and testing thermally conductive copper plates includes a base plate 100 and a clamp 1. The clamp 1 has a clamping plate 2 on its top, and an adjusting screw 3 on one side of the clamping plate 2. The clamping plate 2 has a groove that is narrow on the outside and wide on the inside. The adjusting screw 3 has a protrusion that is narrow on the inside and wide on the outside. The protrusion matches the groove and is inserted into the groove for rotatable connection. The adjusting screw 3 is rotatably connected to the clamping plate 2. A threaded frame 4 is fixedly installed on the top of the clamp 1, and the adjusting screw 3 is threadedly connected to the threaded frame 4. Limiting rods 5 are fixedly installed on both sides of the clamping plate 2, and limiting grooves 6 are opened on both sides of the clamp 1. The limiting rods 5 are inserted into the limiting grooves 6 for slidable connection of the clamp 1. The clamp 1 has multiple strip-shaped openings.
[0026] The strip openings on fixture 1 are used to frame the copper plate 17. Five strip openings are shown in the figure. In actual use, the number of openings can be increased or decreased as appropriate.
[0027] The matching of the narrow outer and wide inner groove with the narrow inner and wide outer protrusion can make the connection between the adjusting screw 3 and the clamp 2 more secure and increase stability. The rotational connection also prevents the clamp 2 from rotating when the adjusting screw 3 rotates.
[0028] The sliding of the limiting rod 5 within the limiting groove 6 restricts the movement path of the clamping plate 2.
[0029] See Figure 1 , Figure 5 , Figure 6 The system includes a lead screw assembly, which includes a threaded rod 7. A worm gear 8 is fixedly mounted on the top of the threaded rod 7. A worm 9 is provided on one side of the limiting groove 6. The worm gear 8 meshes with the worm 9. Two limiting sliders 10 are provided on the worm gear 8. Circular openings are provided on the limiting sliders 10 and the clamp 1. A limiting rod 11 is provided on the limiting slider 10. The limiting rod 11 passes through the circular opening on the limiting slider 10 and is fixedly connected to the limiting slider 10. The limiting rod 11 passes through the circular opening on the clamp 1 and is slidably connected to the clamp 1. A threaded opening is provided on the clamp 1. The threaded opening of the clamp 1 matches the threaded rod 7. The clamp 1 and the threaded rod 7 are threadedly connected. A nut 12 is provided on the threaded rod 7. The nut 12 is threadedly connected to the threaded rod 7 and fixedly installed at the bottom of the lower limiting slider 10.
[0030] The threaded rod 7 is not composed of a complete thread; it has a smooth portion. The limiting slider 10 is rotatably connected to the smooth portion of the threaded rod 7.
[0031] The lead screw assembly allows the clamp 1 to move up and down on the threaded portion of the threaded rod 7, and the limiting bar 11 can increase the stability of the threaded rod 7 during rotation.
[0032] Nut 12 securely fastens the lead screw assembly to the wheel 14. This fastening ensures the stability of the lead screw assembly during operation, preventing displacement due to vibration or external forces. Nut 12 also supports the lead screw assembly, especially under heavy load or high-speed operating conditions. It can withstand the forces and torques transmitted by the lead screw assembly, preventing deformation or damage to the threaded rod 7 due to excessive stress. Simultaneously, the supporting function of nut 12 also helps improve the rigidity and stability of the entire lead screw assembly.
[0033] See Figure 1 , Figure 7 The bottom of the nut 12 is provided with a turntable 13, the turntable 13 is provided with a cylindrical protrusion, the turntable 13 is provided with a rotating wheel 14, the cylindrical protrusion passes through the rotating wheel 14 and is rotatably connected to the rotating wheel 14, the rotating wheel 14 is rotatably connected to the turntable 13, the rotating wheel 14 is fixedly installed at the bottom of the nut 12, and the turntable 13 is fixedly installed at the top of the base plate 100.
[0034] The nut 12 is fixedly installed on the top of the rotating wheel 14. The length of the cylindrical protrusion will not exceed the height of the rotating wheel 14, and it will fit at most at the bottom of the nut 12. When the rotating wheel 14 rotates on the turntable 13, it can drive the entire lead screw assembly to rotate, thereby adjusting the orientation of the clamp 1.
[0035] See Figure 1 , Figure 2 A heating chamber 15 is fixedly installed on the top of the base plate 100, and a fixing frame 16 is fixedly installed on the top of the heating chamber 15. The fixing frame 16 has multiple strip-shaped openings of the same size as the clamp 1, and a copper plate 17 is provided in the strip-shaped openings.
[0036] The strip opening of the fixing bracket 16 and the strip opening of the clamp 1 serve the same function.
[0037] See Figure 1 , Figure 8 A heating plate 18 is fixedly installed on the heating chamber 15, and a copper plate 17 is placed on top of the heating plate 18 and in contact with the heating plate 18.
[0038] The heating plate 18, model number ET-1010, is used to heat the copper plate 17. The copper plate 17 is in direct contact with the heating plate 18. Direct contact between the heating plate 18 and the copper plate 17 reduces the thermal resistance during heat transfer, allowing heat to be transferred to the copper plate 17 more quickly.
[0039] See Figure 2 A limiting plate 19 is fixedly installed on the top of the base plate 100.
[0040] The limiting plate 19 abuts against the grip 3 22, limiting the rotation range of the wheel 14 and also limiting the rotation range of the lead screw assembly.
[0041] See Figure 4 , Figure 6 , Figure 7 A first handle 20 is fixedly installed on one side of the adjusting screw 3. A fixed post is fixedly installed on the top of the base plate 100 near the worm 9. A second handle 21 is fixedly installed at the axis of the worm 9. The second handle 21 passes through the fixed post and is slidably connected to the fixed post. A third handle 22 is fixedly installed on one side of the rotating wheel 14.
[0042] Grip 1 (20), grip 2 (21), and grip 3 (22) facilitate the operation of the heat-conducting copper plate processing and testing device by staff, while the fixing column stabilizes grip 2 (21).
[0043] See Figure 4 The grip 22 abuts against the limiting plate 19, and a square groove is provided at the bottom of the fixing post. After the rotating wheel 14 rotates, the grip 22 can abut against the fixing post.
[0044] The limiting plate 19, the fixing post, and the handle 22 abut against each other, limiting the rotation range of the rotating wheel 14 and the rotation range of the lead screw assembly. When the limiting plate 19 abuts against the handle 22, the strip opening on the clamp 1 is aligned with the copper plate 17. When the fixing post abuts against the handle 22, the copper plate 17 will be aligned with the external collection groove. At this time, the clamping plate 2 will no longer clamp the copper plate 17 by adjusting the adjusting screw 3, and the copper plate 17 will fall into the collection groove.
[0045] Working principle:
[0046] Step 1: The worker places the copper plate 17 into the strip opening in the fixture 1, and then starts the heating plate 18 to heat the copper plate 17 by using an external power source. At the same time, an external testing instrument is used to test the copper plate 17.
[0047] Step Two: After the initial inspection, if further inspection is required, there is no need to disconnect the power to the heating plate 18. At this point, the operator holds handle 21 to rotate the worm gear 9, which in turn rotates the worm wheel 8, causing the threaded rod 7 to rotate. The clamp 1 then moves downwards on the threaded rod 7. When the clamp 1's strip-shaped opening catches the copper plate 17, the operator holds handle 20 to move the adjusting screw 3 within the threaded frame 4 towards the clamping plate 2, pushing the clamping plate 2 to press against the copper plate 17. Once the copper plate 17 is clamped, the operation... The operator holds handle 21 to operate the lead screw assembly. At this time, clamp 1 moves upward on the threaded rod 7, causing copper plate 17 to disengage from the strip opening on the fixed frame 16. Then, the operator holds handle 32 to rotate the wheel 14 on the turntable 13, causing the lead screw assembly to rotate. At this time, clamp 1 also rotates. When the fixed column abuts against handle 32, copper plate 17 will align with the external collection tank. At this time, the clamping plate 2 can be adjusted by adjusting screw 3 to stop clamping copper plate 17, and copper plate 17 will fall into the collection tank.
