Description

Technical Field

[0001] This utility model relates to the field of copper block embedding technology for circuit boards, and in particular to a copper block embedding device for heat dissipation circuit boards. Background Technology

[0002] The copper block embedding device for heat dissipation circuit boards can precisely embed copper blocks into preset positions on the circuit board. Utilizing copper's high thermal conductivity, it quickly conducts heat generated by power components on the circuit board away, effectively reducing component temperature and improving the circuit board's heat dissipation performance. Simultaneously, the device ensures a tight connection between the copper block and the circuit board, enhancing the circuit board's stability and mechanical strength, helping to improve its resistance to deformation, and ensuring the normal operation of the circuit under various environmental conditions.

[0003] In existing technologies, some devices clamp the copper block and press it onto the circuit board. After pressing, workers need to remove it and install the next copper block on the clamping mechanism before pressing it again. This process is cumbersome, resulting in a long pressing time and reduced work efficiency. Utility Model Content

[0004] This utility model proposes a copper block pressing and embedding device for heat dissipation circuit boards, which aims to improve the problem that some existing devices require personnel to handle the copper blocks when embedding circuit boards, resulting in long processing time and reduced work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A copper block pressing device for a heat dissipation circuit board includes a transfer box with multiple sliding grooves on its inner wall. A clamping assembly providing telescopic capability is fixedly connected to the top of the transfer box. The clamping assembly includes a double-headed cylinder, two fixing blocks, multiple fixing posts, and multiple clamping plates. The bottom of the double-headed cylinder is fixedly connected to the top of the transfer box. The two fixing blocks are fixedly connected to the two output ends of the double-headed cylinder. The multiple fixing posts are fixedly connected to the outside of the two fixing blocks. The multiple clamping plates are fixedly connected to the outside of the multiple fixing posts. Outside the fixed column, the inner wall of the transfer box has two sliding grooves three. The inner walls of the multiple fixed columns are slidably connected to protective shells. The bottom of the protective shells is fixedly connected to the top of the transfer box. The outside of the transfer box is fixedly connected to a connecting block. The inside of the connecting block is fixedly connected to two cylinders. The output ends of the two cylinders are fixedly connected to the transfer block. The inner wall of the transfer block has a transfer groove. The inner wall of the transfer box has two sliding grooves one. The inner wall of the transfer box has a discharge groove. The outside of the transfer block is slidably connected to the inside of the two sliding grooves one.

[0007] The above technical solution provides a copper block pressing device for a heat dissipation circuit board, comprising a transfer box with multiple sliding grooves on its inner wall. The top clamping assembly consists of a double-headed cylinder and other components, enabling flexible telescopic clamping. The transfer block slides within the sliding grooves, cooperating with the cylinders to achieve material transfer. The structure is reasonable and the material transfer is stable.

[0008] As a further description of the above technical solution:

[0009] The top of the material transfer box is fixedly connected to a feeding box, which corresponds to the position of the discharge chute. Multiple copper blocks are slidably connected inside the feeding box.

[0010] The above technical solution involves a feed box connected to the top of the transfer box and corresponding to the discharge chute, with multiple copper blocks slidably connected inside. This ensures a continuous and stable supply of copper blocks to the transfer blocks, guaranteeing the continuity of the pressing and embedding process and improving the efficiency of the device.

[0011] As a further description of the above technical solution:

[0012] The connecting block is slidably connected to a support block on its outside. The inner wall of the support block has two limiting grooves. The connecting block is slidably connected to the inside of the two limiting grooves on its outside. The bottom of the support block is fixedly connected to a base plate.

[0013] In the above technical solution, the connecting block and the support block are slidably connected, and the support block has two limiting grooves. The connecting block slides within the limiting grooves, ensuring the accuracy of the connecting block's movement trajectory, avoiding deviation, and providing stable support for the material transfer action of the material transfer block.

[0014] As a further description of the above technical solution:

[0015] The top of the support block is provided with a synchronous lifting assembly that provides rotation capability. The synchronous lifting assembly includes a motor, a threaded rod, and a drive wheel. The bottom of the motor is fixedly connected to the top of the support block. One end of the threaded rod is fixedly connected to the output end of the motor. The outside of the threaded rod is rotatably connected to the inner wall of the base plate. The inner wall of the connecting block is threadedly connected to the outside of the threaded rod. The inner wall of the drive wheel is fixedly connected to the outside of the threaded rod.

[0016] The above technical solution features a synchronous lifting assembly at the top of the support block. A motor drives a threaded rod to rotate, causing the connecting block to rise and fall along the threaded rod. The drive wheel rotates accordingly, enabling synchronous lifting and lowering of the connecting block and the material transfer block, thus precisely controlling the material transfer height.

[0017] As a further description of the above technical solution:

[0018] The inner wall of the base plate is rotatably connected to a rotating shaft, and a driven wheel is fixedly connected to the outside of the rotating shaft. A belt is connected to the outside of the driven wheel and the outside of the drive wheel for transmission.

[0019] In the above technical solution, there is a driven wheel on the rotating shaft inside the base plate, which is driven by the drive wheel via a belt. This allows the power of the motor to be transmitted to the rotating shaft, enabling the rotating shaft to rotate stably and providing power for the subsequent clamping block movement.

[0020] As a further description of the above technical solution:

[0021] A connecting plate is movably connected to the top of the base plate, and the outer side of the rotating shaft is rotatably connected to the inner wall of the connecting plate. Two connecting pieces are fixedly connected to the outer side of the rotating shaft.

[0022] In the above technical solution, the connecting plate at the top of the base plate is rotatably connected to the rotating shaft, and there are two connecting plates on the rotating shaft. This structure makes the rotation of the rotating shaft more stable and facilitates cooperation with other components, making it easier for the clamping block to complete the clamping action.

[0023] As a further description of the above technical solution:

[0024] Multiple L-shaped rods are rotatably connected inside the two connecting pieces. Rotating bolts are inserted and connected to the outside of the two connecting pieces and the inner wall of the L-shaped rods. Clamping blocks are rotatably connected to the outside of the L-shaped rods. Two fixing rings are fixedly connected to the outside of the rotating shaft.

[0025] In the above technical solution, multiple L-shaped rods within the connecting piece are connected by rotating bolts, and each rod has a clamping block at its end. When the rotating shaft rotates, the clamping blocks can open and close flexibly, effectively clamping the copper block and meeting the clamping requirements of the pressing and embedding device.

[0026] As a further description of the above technical solution:

[0027] The bottom of the base plate is fixedly connected to two sets of feet. Multiple bolts are passed through and connected to the outside of the connecting plate and the inner wall of the base plate. The top of the base plate is fixedly connected to a shell, and two lights are fixedly connected to the outside of the shell.

[0028] The above technical solution features feet at the bottom of the base plate to ensure stable placement of the device. The connecting plate is bolted to the base plate for easy disassembly and maintenance. An onboard light provides illumination, facilitating operation and observation of the device's working status.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, copper blocks are sequentially placed into the feeding box. Under the influence of gravity, the copper blocks undergo free-falling motion. The bottom copper block falls into the transfer groove. A cylinder is activated to transmit power, pushing the transfer block towards the discharge groove. Simultaneously, a double-headed cylinder is activated, causing two fixed blocks to slide inside the second sliding groove. As the fixed blocks slide, the fixed posts and clamping plates move towards the center of the double-headed cylinder, firmly clamping the copper block pushed towards the discharge groove. The cylinder then activates and retracts, returning the transfer block to its initial state, and the copper block falls back into the transfer groove. This structure achieves orderly and rapid copper block discharge, solving the problem of long processing times and low work efficiency in some devices when embedding circuit boards, where copper blocks need to be handled manually.

[0031] 2. In this invention, a rotating shaft rotates, causing the connecting piece to rotate. The connecting piece then drives the L-shaped rod to rotate synchronously. Under the rotational force provided by the rotating bolt, the L-shaped rod converts the rotational force provided by the connecting piece into a pulling force. Therefore, the L-shaped rod pulls the clamping block towards the center point of the rotating shaft. This structure achieves a stable clamping effect on the circuit board, solving the problem of circuit board wobbling when the copper block is fitted onto the circuit board in some devices.

Two connecting pieces 26 are fixedly connected to the outside of the rotating shaft 23, forming a rotating structure with the L-shaped rod 27. Multiple L-shaped rods 27 are rotatably connected inside the two connecting pieces 26, driving the clamping block 29 to perform a clamping action. Rotating bolts 28 are passed through and connected to the outside of the two connecting pieces 26 and the inner wall of the L-shaped rod 27, allowing the L-shaped rod 27 and the connecting piece 26 to rotate flexibly.

[0049] Working principle: The operator places multiple copper blocks 14 to be embedded into the feeding box 13 in sequence. The inner wall of the feeding box 13 is relatively smooth to prevent the edges and corners of the copper blocks 14 from being damaged by friction with the inner wall of the feeding box 13 when they fall. In the initial state, the position of the transfer groove 12 corresponds to the position of the feeding box 13. Due to the influence of gravity, the copper blocks 14 fall freely. Then, the copper block 14 at the bottom falls into the transfer groove 12. The cylinder 10 is activated to transmit power, causing the transfer block 11 to be pushed towards the discharge groove 15. Simultaneously, the double-headed cylinder 3 is activated, causing the two fixed blocks 4 to slide inside the slide groove 2. As the fixed blocks 4 slide, the fixed column 5 and the clamping plate 6 move closer to the center of the double-headed cylinder 3, causing the copper block 14, which is pushed to the discharge chute 15, to fall and be firmly clamped by multiple clamping plates 6. Then, the cylinder 10 is activated and retracted, causing the transfer block 11 to return to its initial state. At this time, the transfer chute 12 returns to the bottom of the feed box 13 and corresponds to it, so that the subsequent copper block 14 can fall into the interior of the transfer chute 12 again, ready for the processing of the next copper block 14.

[0050] The circuit board is placed between multiple clamping blocks 29. The motor 18 is started, which drives the threaded rod 19 to rotate. At the same time, the threaded rod 19 drives the drive wheel 20 to rotate. Since the drive wheel 20 is larger than the driven wheel 21, the drive wheel 20 rotates at a higher speed than the driven wheel 21. At the same time, the driven wheel 21 also rotates synchronously under the power transmission provided by the belt 22. The rotation of the driven wheel 21 causes the rotating shaft 23 to rotate as well. The rotation of the rotating shaft 23 drives the connecting piece 26 to rotate. The connecting piece 26 drives the L-shaped rod 27 to rotate synchronously. Under the rotational force provided by the rotating bolt 28, the L-shaped rod 27 converts the rotational force provided by the connecting piece 26 into a pulling force. Therefore, the L-shaped rod 27 pulls the clamping block 29 to clamp towards the center point of the rotating shaft 23.

[0051] Therefore, the circuit board is firmly clamped in the middle of multiple clamping blocks 29. At the same time, the copper block 14, which is held in the middle of multiple clamping plates 6, also moves downward to provide downward pressure, firmly pressing the copper block 14 into the circuit board. Then, the double-headed cylinder 3 is activated, which drives the clamping plate 6 to expand, release the copper block 14, and complete the pressing and embedding work.
