Description

Technical Field

[0001] This invention relates to the field of printed circuit boards, and more particularly to a copper block for use in embedded copper block products. Background Technology

[0002] Printed circuit boards (PCBs) are the providers of electrical connections for electronic components.

[0003] As electronic products continue to develop towards multifunctionality and high performance, the electronic components in these products are becoming increasingly centralized. These highly centralized electronic components generate heat during operation. In order to effectively dissipate this heat, copper blocks are placed in the PCB board as heat sinks. When installing these copper blocks, the embedded copper block technology is used.

[0004] Existing copper embedding technology typically involves cutting grooves in the PP (polypropylene) and substrate to hold the copper block before lamination. The PP and substrate are then fused together, and the copper block is placed in the groove within the fused substrate. Lamination is then performed, with adhesive flowing into the gap between the copper block and the groove. After lamination, the PP solidifies, thus fixing the copper block to the PCB. Because adhesive is needed to fix the copper block, only thicker PP models with higher adhesive content can be selected, limiting its application. Furthermore, the high-speed rotation of the milling cutter during grooving generates significant heat, causing the PP to melt at the contact surface with the milling cutter, making it difficult to control the groove dimensions.

[0005] Therefore, it is necessary to provide a copper block for embedded copper block products to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention provides a copper block for embedded copper products, solving the problems of existing technologies that require PP adhesive to fix the copper block, thus limiting the application of PP to thicker models with higher adhesive content, and the difficulty in controlling the groove size due to the high-speed rotation of the milling cutter during grooving when the PP is grooved before pressing.

[0007] To solve the above-mentioned technical problems, the present invention provides a copper block for embedding copper blocks, comprising: a worktable;

[0008] A connecting frame is fixedly installed on both sides of the workbench. A conveyor belt structure is fixedly installed on the inner side of the connecting frame.

A connecting column is fixedly connected to the inner side of the first slider. A pad is fixedly installed on the inner side of the connecting column and located on the inner side of the conveyor belt structure. A second telescopic rod is fixedly installed on the top of the connecting column. The top of the second telescopic rod is fixedly connected to the bottom of the fixed frame.

[0011] A copper block is disposed on the top left side of the conveyor belt structure. The front and back of the copper block are provided with slots for the product, and copper sheets are fixedly connected to both sides of the top of the copper block.

[0012] Preferably, adjustable leveling support feet are fixedly installed around the bottom of the workbench and on the outer side of the bottom of the connecting frame.

[0013] Preferably, guide plates are fixedly installed on both the front and back sides of the inner side of the fixing frame.

[0014] Preferably, a third telescopic rod is fixedly installed on both sides of the bottom of the fixing frame, and a fixing frame is fixedly installed at the bottom of the fixed end of the third telescopic rod.

[0021] Compared with related technologies, the copper block for embedding copper blocks provided by the present invention has the following beneficial effects:

[0022] This invention provides a copper block for embedded copper products. Through the interplay of a worktable, connecting frame, conveyor belt structure, motor, fixing frame, first telescopic rod, working plate, first slide groove, first slider, connecting column, pad, second telescopic rod, copper block, copper sheet, and a product with slots, the copper sheet is deformed in its intended direction and positioned at the top of the product with slots. Combined with the T-shape of the copper block itself, the copper block is fixed to both sides of the product with slots. This eliminates the need for a copper block browning process, physically fixing the copper block without the need for browning. Furthermore, the copper block is fixed after pressing the product, allowing for customization of the copper block thickness based on the actual plate thickness. It also avoids the problem of difficult dimensional control during PP slotting. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] First Embodiment

[0035] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a copper block for embedding copper blocks provided by the present invention; Figure 2 for Figure 1 The diagram shows a three-dimensional external structure of the copper block. Figure 3 for Figure 1 The diagram shows a cross-sectional view of the conveyor belt structure. A copper block for embedding copper blocks in a product includes: a worktable 1;

[0036] A connecting frame 2 is fixedly installed on both sides of the workbench 1. A conveyor belt structure 3 is fixedly installed on the inner side of the connecting frame 2. A motor 4 is fixedly installed on the right side of the front of the connecting frame 2. One end of the output shaft of the motor 4 is fixedly installed to the outer side of the conveyor belt structure 3.

[0037] The conveyor belt structure 3 includes two rotating shafts, which are respectively installed inside the connecting frame 2 on both sides of the workbench 1. The surface of the rotating shaft is covered with a conveyor belt. One end of the output shaft of the motor 4 is fixedly installed with one of the rotating shafts. When the motor 4 rotates, it drives the rotating shaft to rotate, which in turn drives the conveyor belt to rotate, and thus drives the other rotating shaft to rotate.

[0038] A fixed frame 6 is fixedly installed on the top of the workbench 1. A first telescopic rod 7 is fixedly installed on both the front and back of the top of the fixed frame 6. A work plate 8 is fixedly installed on the bottom of the first telescopic rod 7 and on the inner side of the fixed frame 6.

[0039] The bottom of the working plate 8 has inclined polygonal grooves on both sides, so that when the working plate 8 moves downward, the copper sheet 17 can contact the inner side of the inclined polygonal groove. Due to the inclined state, the copper sheet 17 can be bent from the inside to the outside by the squeezing force.

[0040] The first chute 9 is formed on both sides inside the fixed frame 6. The first slider 10 is slidably connected inside the first chute 9. The connecting column 11 is fixedly connected to the inner side of the first slider 10. The pad 12 is fixedly installed on the inner side of the connecting column 11 and located on the inner side of the conveyor belt structure 3. The second telescopic rod 13 is fixedly installed on the top of the connecting column 11. The top of the second telescopic rod 13 is fixedly connected to the bottom of the fixed frame 6.

[0041] When its pad 12 contacts the bottom of the inner side of the conveyor belt structure 3, it provides support and padding for that part of the conveyor belt structure 3, so as to prevent the conveyor belt structure 3 from being deformed or damaged due to the pressure of the working plate 8 pressing down on the copper sheet 17 and copper block 16.

[0042] A copper block 16 is disposed on the top left side of the conveyor belt structure 3. Both the front and back sides of the copper block 16 are provided with products 18 with slots. Copper sheets 17 are fixedly connected to both sides of the top of the copper block 16.

[0043] The copper block 16 is T-shaped with protruding sides at its bottom, which allows it to be held in place by the bent copper sheet 17, thus clamping the product 18 with its slots on both sides.

[0044] Adjustable horizontal support feet 5 are fixedly installed around the bottom of the workbench 1 and on the outer side of the bottom of the connecting frame 2.

[0045] The adjustable horizontal support feet 5 support the overall worktable 1 and connecting frame 2, and the horizontal state can be adjusted according to the actual placement position, thus improving the stability of the overall structure during operation.

[0046] The guide plate 15 is fixedly installed on both the front and back sides of the inner side of the fixing frame 6.

[0047] The guide plate 15 allows the product to be positioned as it moves from left to right on top of the conveyor belt structure 3. If the product is misaligned, the guide plate 15 will bring it back to the center position, so that when it moves to the bottom of the working plate 8, the longitudinal position between the two can be aligned.

[0048] The working principle of the copper block for embedded copper products provided by this invention is as follows:

[0049] When operation is required, the copper block 16 can be placed on the top left side of the conveyor belt structure 3, and the two products 18 with slots can be placed on the front and back of the copper block 16 respectively, on the protruding part on the outer side of the bottom of the copper block 16. Then, the motor 4 can be started, and the rotation of the motor 4 will drive the conveyor belt structure 3 to rotate. Thus, the copper block 16 and the products 18 with slots can be conveyed from left to right by the rotation of the conveyor belt structure 3 until they are conveyed to the bottom of the work plate 8. Then, the operation of the motor 4 can be stopped.

[0050] At the same time, the second telescopic rod 13 is activated, and the retraction of the second telescopic rod 13 drives the connecting column 11 to move upward. The upward movement of the connecting column 11 then drives the first slider 10, causing the first slider 10 to move synchronously inside the first slide groove 9. The movement of the first slider 10 then drives the pad 12 to move upward in the middle position of its conveyor belt structure 3 until the top of the pad 12 contacts the bottom of the conveyor belt structure 3.

[0051] Then, by activating the first telescopic rod 7, the extension of the first telescopic rod 7 pushes the working plate 8 downward, causing the working plate 8 to move downward inside its fixing frame 6. As the working plate 8 moves downward, it comes into contact with the top of the copper sheet 17. Due to the polygonal groove at the bottom of the working plate 8, when the top of the copper sheet 17 contacts the inner side of the polygonal groove, and as the working plate 8 moves downward, the copper sheet 17 is subjected to an outward bending force, causing the copper sheet 17 to gradually bend from the inside to the outside. As the copper sheet 17 continues to move downwards, it bends at approximately 90 degrees, causing it to bend to the top of the product 18 with the slot. The T-shape of the copper sheet 17, along with its protruding bottom portion, supports the product 18 with the slot. Simultaneously, the 90-degree bend of the copper sheet 17 physically clamps the product 18 with the slot onto both sides of the copper block 16, completing the pressing process. Then, by activating the first telescopic rod 7, it retracts, causing the working plate 8 to move upwards and reset.

[0052] Then, motor 4 is restarted, and the rotation of motor 4 drives the conveyor belt structure 3 to rotate, so that the pressed product continues to be transported from the right side, so that it is removed from the processing position.

[0053] Compared with related technologies, the copper block for embedding copper blocks provided by the present invention has the following beneficial effects:

[0054] The copper sheet 17 is deformed in its usage direction and positioned on top of the product 18 with the slot, through the mutual cooperation and extrusion of the worktable 1, connecting frame 2, conveyor belt structure 3, motor 4, fixing frame 6, first telescopic rod 7, working plate 8, first slide 9, first slider 10, connecting column 11, pad 12, second telescopic rod 13, copper block 16, copper sheet 17, and product 18 with slot, etc., and in conjunction with the T-shape of the copper block 16 itself, the copper block 16 is fixed on both sides of the product 18 with slot, saving the process of browning the copper block 16. The copper block 16 is physically fixed, and the copper block 16 does not need to be browned. At the same time, the copper block 16 is fixed after the product is pressed. The thickness of the copper block 16 can be customized according to the actual plate thickness, and the problem of difficult size control when PP is slotted is also avoided.

[0055] Second Embodiment

[0056] Please refer to the following: Figure 4 and Figure 5 Based on the copper block for embedding copper blocks provided in the first embodiment of this application, the second embodiment of this application proposes another copper block for embedding copper blocks. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0057] Specifically, the second embodiment of this application provides a copper block for embedding copper blocks, wherein a third telescopic rod 19 is fixedly installed on both sides of the bottom of the fixing frame 6, and a fixing frame 20 is fixedly installed at the bottom of the fixed end of the third telescopic rod 19.

[0058] The top of both sides of the fixed frame 20 is fixedly installed with a fourth telescopic rod 21, and the top of the output end of the fourth telescopic rod 21 is fixedly installed with a hollow fixed frame 22.

[0059] When the hollow fixed frame 22 moves, it moves on the surface of the third telescopic rod 19. The hollow fixed frame 22 has a reserved hole inside, and the third telescopic rod 19 is inside the reserved hole. Therefore, the hollow fixed frame 22 does not affect the normal operation of the overall structure during operation.

[0060] The fixed frame 20 has a second sliding groove 23 on both sides of its inner perimeter, and a second slider 24 is slidably connected inside the second sliding groove 23.

[0061] The interaction between the second slide 23 and the second slider 24 improves the stability of the movement of the first connecting rod 25, and also improves the stability of the movement and operation between the second connecting rod 27 and the third connecting rod 28, thus preventing it from easily shaking due to external forces.

[0062] The second slider 24 is rotatably connected to the first connecting rod 25 on its outer side.

[0063] A control plate 26 is rotatably connected to the bottom of the inner perimeter of the fixed frame 20, and the top of the outer side of the control plate 26 is rotatably connected to the other end of the first connecting rod 25.

[0064] A second connecting rod 27 is fixedly connected to the inner side of the second slider 24, and a third connecting rod 28 is fixedly installed on the top of the second connecting rod 27.

[0065] The side lengths of products of different sizes are in a proportional relationship. Therefore, by extending or retracting the fourth telescopic rod 21, the space used in front of the four control panels 26 is adjusted proportionally, thus satisfying the operation of converging and centralizing products of different sizes.

[0066] The top of the third connecting rod 28 is fixedly connected to the bottom of the hollow fixed frame 22.

[0067] The working principle of the copper block for embedded copper products provided by this invention is as follows:

[0068] When the fixed frame 20 enters the working state, the fourth telescopic rod 21 can be activated according to the actual size of the product. The retraction or extension of the fourth telescopic rod 21 drives the hollow fixed frame 22 to move. The movement of the hollow fixed frame 22 then drives the third connecting rod 28 to move, which in turn drives the second connecting rod 27 to move. The movement of the second connecting rod 27 synchronously drives the second slider 24, causing it to move up and down inside the second slide groove 23. The movement of the second slider 24 then drives the first connecting rod 25 to move. The angle change caused by the movement of the first connecting rod 25 drives the top of the control plate 26 to move. At this time, the control plate 26 rotates around the part where its bottom is rotatably connected to the inner side of the fixed frame 20, thus changing the working angle of the control plate 26 until the distance between the tops of the control plates 26 in the four different positions is the same as the side length of the product.

[0069] Meanwhile, the product is directly below the fixed frame 20. Then, by activating the third telescopic rod 19, the fixed frame 20 is pushed downwards until the fixed frame 20 fits over the product and the product is simultaneously inside the control plate 26. When the fixed frame 20 fits over the product, the outer side of the product contacts the inner side of the control plate 26. As the fixed frame 20 moves downwards, and because the bottom spacing of the control plates 26 is greater than the top spacing, the control plates 26 move downwards towards the middle of the fixed frame 20, causing the product to gather together until the product is completely gathered between the four control plates 26 and inside the fixed frame 20. Then, the product can be pressed together inside the control plates 26 and inside the fixed frame 20.

[0070] Compared with related technologies, the copper block for embedding copper blocks provided by the present invention has the following beneficial effects:

[0071] The cooperation between the third telescopic rod 19, the fixed frame 20, the fourth telescopic rod 21, the hollow fixed frame 22, the second slide groove 23, the second slider 24, the first connecting rod 25, the control plate 26, the second connecting rod 27, and the third connecting rod 28 ensures that the product is positioned inside the fixed frame 20 during pressing. The fixed frame 20 also restricts the position of the product, preventing positional shifts during pressing. Furthermore, the size of the space within the fixed frame 20 can be adjusted according to the size of the product, thus improving the overall adaptability of the structure.

[0072] Third Embodiment

[0073] Please refer to the following: Figure 6 and Figure 7 Based on the copper block for embedding copper blocks provided in the first embodiment of this application, the third embodiment of this application proposes another copper block for embedding copper blocks. The third embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the separate implementation of the first embodiment.

[0074] Specifically, the third embodiment of this application provides a copper block for embedding copper blocks, which differs in that the bottom of the guide plate 15 is provided with a mounting bracket 29, the inner side of the mounting bracket 29 is rotatably connected with a threaded rod 30, both sides of the surface of the threaded rod 30 are fitted with threaded blocks 31, and the top and bottom of the inner side of the mounting bracket 29 and the top and bottom of the threaded rod 30 are provided with third sliding grooves 32, and both sides of the inner side of the third sliding groove 32 are slidably connected with third sliders 33.

[0075] The inner side of the third slider 33 is fixedly connected to the outer side of the threaded block 31 via a mounting post. The back of the mounting post is rotatably connected to a fifth connecting rod 34, and the top of the fifth connecting rod 34 is rotatably connected to the bottom of the guide plate 15.

[0076] The fifth connecting rod 34 can only move laterally during the movement, but cannot move up and down. Therefore, it can effectively support the guide plate 15 while changing its position.

[0077] Two different threads are provided on both sides of the surface of the threaded rod 30. These threads are compatible with the threaded blocks 31 sleeved on both sides of the surface of the threaded rod 30. Due to the different threads, the threaded blocks 31 sleeved on both sides of the surface can move in opposite directions by rotating the threaded rod 30. A rotating ring is fixedly installed on the surface of the threaded rod 30 and inside the threaded blocks 31. The rotating ring allows the operator to easily rotate the threaded rod 30.

[0078] The working principle of the copper block for embedded copper products provided by this invention is as follows:

[0079] When it is necessary to change the working position of the guide plate 15, the rotating ring can be manually rotated, which in turn drives the threaded rod 30 to rotate. The rotation of the threaded rod 30 causes the threaded blocks 31 sleeved on both sides of the surface of the threaded rod 30 to move in opposite directions. The movement of the threaded blocks 31 then drives the mounting column to move.

[0080] The movement of the mounting column then drives the third slider 33, causing it to move synchronously within the third groove 32. The movement of the mounting column then drives the fifth connecting rod 34, and the angle change caused by the movement of the fifth connecting rod 34 will drive the guide plate 15 to move, thus changing the position of the guide plate 15 until it is adjusted to a suitable state.

[0081] Compared with related technologies, the copper block for embedding copper blocks provided by the present invention has the following beneficial effects:

[0082] The mutual cooperation between the mounting bracket 29, threaded rod 30, threaded block 31, third slide groove 32, third slider 33, and fifth connecting rod 34 allows the guide plate 15 to be adjusted in position according to the actual situation during use. Therefore, it can guide products of different sizes and avoid positional deviation during movement, which would affect the subsequent pressing work.

[0083] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
