Description

Technical Field

[0001] The invention relates to the technical field of radiator processing, in particular to an automatic foot pressing machine for notebook computer radiators. Background Art

[0002] The radiator support foot (also known as a radiator clip or fixing bracket) is a key structural component used to precisely fix the radiator to the surface of an electronic device (such as a CPU / GPU). Its coplanarity and angular accuracy directly affect the contact pressure and thermal conductivity between the radiator and the chip.

[0003] In the prior art manufacturing process of laptop computer radiators, in order to meet the compact space layout of the laptop due to its portability, it is usually necessary to design the foot into a multi-section bending mechanism (such as a Z-type) to achieve the dual functions of avoiding components and dispersing mechanical stress. The traditional method usually uses the cooperation of a punch and a die to bend the foot, and controls the bending angle by the mold surface. However, the bending angle of the mold cannot be changed. When bending the foot of the support pad of different metal materials, the yield strength and elastic modulus of different metal materials are different, and the rebound angle after bending is different. A single mold cannot adapt to the rebound of multiple materials, resulting in the bottom of the foot after bending being unable to remain level with the motherboard, thereby causing the radiator to tilt after installation, uneven local contact pressure, and a significant decrease in thermal conductivity.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the process of processing the foot of the notebook radiator, the present invention utilizes a sliding seat, a blocking rod, a rotating plate, a pushing rod and a guide groove.

[0019] 3. During the processing of the foot of the notebook radiator, the present invention utilizes a blocking rod to make the blocking rod move away from the foot before the foot is bent for the first time, thereby ensuring the bending effect of the foot and preventing the blocking rod from blocking the bending of the foot, causing the foot to bend and thus affecting the subsequent installation of the radiator. Moreover, the bent foot can be moved out from under the L-shaped mounting plate and will not be blocked by the mounting plate, thereby ensuring the rapid replacement of the radiator after the bending process.

DETAILED DESCRIPTION

[0035] See also Figures 1-14 The present invention provides a technical solution: an automatic foot presser for a laptop computer radiator, comprising a base 1, a T-shaped processing table 2, a support rod 3, a fixing plate 4, a U-shaped limiting plate 6 arranged on the surface of the fixing plate 4 and located above the processing table 2 through a connecting rod 5, and a radiator 7 placed between the processing table 2 and the limiting plate 6;

[0036] The surface of the fixed plate 4 is equipped with two first cylinders 8 for bending the foot 701 downward. The left and right sides of the processing table 2 are equipped with second cylinders 9 for bending the foot 701 to the horizontal. The surface of the base 1 is provided with a blocking rod 10 with an arc-shaped bottom for blocking the foot 701 after bending downward. The second cylinder 9 is elastically connected to the sliding seat 12 on the side close to the foot 701 through the first sliding groove 11. The surface of the sliding seat 12 is hinged with a rotating plate 13, and the bottom of the rotating plate 13 is hinged with a top rod 14. The surface of the moving rod 14 is vertically slidably connected to a stabilizing block 15. A groove 16 is provided on the surface of the second cylinder 9 corresponding to the position of the pushing rod 14. The inner wall surface of the groove 16 is provided with an inclined guide groove 17 and a horizontally arranged stabilizing groove 18. The pushing rod 14 is located in the groove 16 and the bottom slides in the guide groove 17. The stabilizing block 15 slides in the stabilizing groove 18. A limiting mechanism for limiting the sliding seat 12 is provided on the surface of the sliding seat 12. The limiting mechanism can release the limit of the sliding seat 12 when it contacts the blocking rod 10.

[0037] In the process of processing the foot 701 of the notebook radiator 7, the radiator 7 needs to be moved between the processing table 2 and the limiting plate 6 first. The limiting plate 6 can limit the radiator 7 so that the radiator 7 fits the surface of the processing table 2. The supporting feet 701 on both sides of the radiator 7 extend to the outside of the processing table 2. Then the first cylinder 8 is extended to bend the feet 701 on both sides of the radiator 7 downward. After the feet 701 are bent, the blocking rod 10 moves closer to the feet 701 and moves away from the feet 701. The cylinder 9 fits one side, and then the second cylinder 9 extends to cooperate with the stop rod 10 to bend the bottom of the foot seat 701 to the horizontal. At this time, the sliding seat 12 is limited by the limiting mechanism, and the sliding seat 12 and the rotating plate 13 are driven by the second cylinder 9. The bent foot seat 701 fits the rotating plate 13. Then, after the foot seat 701 is bent, the second cylinder 9 drives the sliding seat 12 to move to the position of the stop rod 10. The limiting mechanism releases the limit of the sliding seat 12 when the stop rod 10 is triggered, and then the second cylinder 9 continues to extend the sliding seat 12 and is stopped by the stop rod. 10 blocks and drives the rotating plate 13 to slide in the first sliding groove 11, and the rotating plate 13 drives the pushing rod 14 to move in the groove 16. The stabilizing block 15 can keep the pushing rod 14 vertical during the movement along the stabilizing groove 18, and the guide groove 17 enables the pushing rod 14 to move upward during the movement. The rotating plate 13 is lifted by the pushing rod 14 and rotates around the sliding seat 12. The rotation of the rotating plate 13 can drive the bent foot 701 to continue to flip upward, and over-bend the foot 701 at a certain angle, so as to adapt to the rebound angle of the foot 701, and the position of the pushing rod 14 and the angle of the rotating plate 13 can be adjusted by controlling the extension amount of the second cylinder 9, so as to realize the control of the bending angle when different foot 701 is over-bent, simplify the operation when bending foot 701 made of different materials, and ensure that foot 701 made of different materials can be quickly bent to a horizontal state, so that the installed radiator 7 can be kept level with the motherboard, ensuring balanced contact pressure with electronic components and improving heat dissipation efficiency.

[0038] As a further solution of the present invention, the limiting mechanism includes a push rod 19 that elastically slides laterally on the surface of the sliding seat 12 and penetrates the sliding seat 12, a limiting rod 20 that slides vertically on the surface of the sliding seat 12 and penetrates the sliding seat 12, and an inclined groove 21 is formed on the surface of the limiting rod 20. The push rod 19 slides in the inclined groove 21 through a fixed rod 22, and a limiting groove 23 is formed in the first sliding groove 11;

[0039] When the foot 701 of the notebook radiator 7 is processed, the limit rod 20 is in the limit groove 23 to limit the sliding seat 12, and the second cylinder 9 drives the sliding seat 12 to move synchronously with the rotating plate 13. The foot 701 is bent to a horizontal position under the pushing action of the rotating plate 13 and the second cylinder 9 and the blocking of the blocking rod 10. The top rod 19 passes through the multiple foot seats 701 and moves to the position of the blocking rod 10 and is blocked by the blocking rod 10. The top rod 19 moves in the opposite direction of the moving direction of the second cylinder 9 under the blocking of the blocking rod 10. The top rod 19 is guided by the fixed rod 22 and the inclined groove 21 to limit the limit rod 20 upward, and the limit rod 20 moves upward out of the limit groove 23 to release the limit on the sliding seat 12, thereby realizing that the limit of the sliding seat 12 can be automatically released after the foot 701 is bent to a horizontal position, without the need for additional operation, and the second cylinder 9 can automatically release the limit of the sliding seat 12 when the foot 701 is bent to a horizontal position. When the second cylinder 9 retracts, the push rod 19 and the stop rod 10 are disengaged and return to their original positions under the action of the spring, the limit rod 20 moves downward under the action of the fixed rod 22 and the limit groove 23 and fits the bottom of the groove 16. Then, when the sliding seat 12 drives the limit rod 20 to continue to move to the position of the limit groove 23, the limit rod 20 can move back to the limit groove 23 to limit the sliding seat 12, and the rotating plate 13 returns to the horizontal state, leaving space for the rebound of the foot seat 701, which is convenient for observing the rebound degree of the foot seat 701 when bending the foot seat 701 of the material with unclear rebound angle. The push rod 19 and the limit rod 20 can automatically limit and release the sliding seat 12 when the second cylinder 9 moves back and forth, so as to adapt to multiple bending tests of the foot seat 701 by the second cylinder 9.

[0040] When processing the foot 701 of the notebook radiator 7, the blocking rod 10 can easily block the bending of the foot 701 when the foot 701 bends for the first time. As a further solution of the present invention, two L-shaped mounting plates 24 are fixedly connected to the surface of the base 1. The blocking rod 10 elastically slides on the two mounting plates 24 through the through groove 25. The bottom of the second cylinder 9 is fixedly connected to an extrusion plate 26 with an inclined bottom. When the extrusion plate 26 moves downward, it can squeeze and push the blocking rod 10 to move toward the side close to the foot 701.

[0041] Before processing the foot 701 of the notebook radiator 7, the baffle 10 is in the through groove 25 away from the side of the radiator 7. Then, when the first cylinder 8 bends the foot 701, the foot 701 can rotate downward from the side of the baffle 10, and the baffle 10 will not affect the bending of the foot 701. Then, after the foot 701 is bent, the first cylinder 8 continues to extend to drive the extrusion plate 26 to move to the position of the baffle 10, and squeezes the baffle 10 to move toward the side close to the foot 701. The baffle 10 moves to the through groove 2 5 is close to one side of the radiator 7 and fits with the foot 701, so that the blocking rod 10 is at a position away from the foot 701 before the foot 701 is bent for the first time, thereby ensuring the bending effect of the foot 701 and preventing the blocking rod 10 from blocking the bending of the foot 701, causing the foot 701 to bend and thus affecting the subsequent installation of the radiator 7. Moreover, the bent foot 701 can be moved out from under the L-shaped mounting plate 24 without being blocked by the mounting plate 24, thereby ensuring the rapid replacement of the radiator 7 after the bending process.

[0042] During the processing of the foot 701 of the notebook radiator 7, the foot 701 is bent once without any obstruction, and it is difficult to bend the foot 701 to a vertical position. As a further solution of the present invention, the left and right sides of the processing table 2 are elastically and slidably connected with L-shaped push blocks 28 through the second slide groove 27. The upper end of the push block 28 extends to the bottom of the foot 701. The front and rear ends of the surface of the processing table 2 corresponding to the push block 28 are rotatably connected with synchronous rollers 29 that are transmission-connected to the bottom of the push block 28. The front and rear surfaces of the processing table 2 are both slidably connected with L-shaped driving plates 30 with inclined upper ends. The driving plates 30 are transmission-connected to the synchronous rollers 29. The driving plates 30 extend to the bottom of the first cylinder 8. When the first cylinder 8 moves downward, it can squeeze and push the driving plates 30 to move.

[0043] During the processing of the foot seat 701 of the notebook radiator 7, when the first cylinder 8 is extended to the position of the driving plate 30, the first cylinder 8 squeezes the driving plate 30 through the inclined surface at the upper end of the driving plate 30 to move, and the driving plate 30 drives the pushing block 28 to move out of the second slide groove 27 through the synchronous roller 29. The end of the pushing block 28 moves to the bottom of the foot seat 701. The pushing block 28 is synchronously moved out when the first cylinder 8 is extended, so that the pushing block 28 can be extended from the bottom of the foot seat 701 to a predetermined bending position, thereby avoiding that when the radiator 7 and the foot seat 701 move toward the surface of the processing table 2, part of the foot seat 701 is in a tilted state, and the pushing block 28 cannot move to an extended state. The first cylinder 8 then moves to the side of the drive plate 30 and fits the side of the first cylinder 8. The first cylinder 8 continues to move to the lower end portion to the position of the foot 701 and cooperates with the push block 28 to bend the foot 701. The push block 28 supports the foot 701 so that the foot 701 can bend at a predetermined position, avoiding the bottom of the foot 701 having no support and the bending position of the foot 701 cannot be determined, thereby causing the bent foot 701 to be unable to be installed so that the radiator 7 is parallel to the motherboard, affecting the heat dissipation effect of the radiator 7.

[0044] During the processing of the foot 701 of the notebook radiator 7, when the first cylinder 8 bends the foot 701, the foot 701 above the push block 28 bulges due to the torsional force during the bending, affecting the bending effect of the foot 701. As a further solution of the present invention, a pressing plate 31 is elastically and slidably connected to the side of the first cylinder 8 near the foot 701. The pressing plate 31 is located between the limit plate 6 and the push block 28.

[0045] During the processing of the foot 701 of the notebook radiator 7, the first cylinder 8 drives the pressing plate 31 to move together when it is extended, and then after the pushing block 28 is extended, the pressing plate 31 moves to the top of the foot 701 and presses down the foot 701, so that the part of the foot 701 above the pushing block 28 before bending can be pressed down to a horizontal state, and the bending position can be fitted with the top of the pushing block 28 under the downward pressure of the pressing plate 31, thereby ensuring the bending effect of the foot 701.

[0046] During the processing of the foot 701 of the laptop radiator 7, when the radiator 7 is moved toward the surface of the processing table 2, it is difficult to ensure that the foot 701 is placed on both sides of the processing table 2 at the same length after multiple moves. As a further solution of the present invention, a guiding inclined surface 32 is provided on the inner side of the limiting plate 6 for guiding the movement of the radiator 7;

[0047] During the processing of the foot 701 of the notebook radiator 7, when the radiator 7 is moved between the limit plate 6 and the processing table 2, the guiding slope 32 on the inner side of the limit plate 6 can guide the position of the radiator 7, so that the length of the foot 701 on both sides of the processing table 2 is the same, ensuring that the length of the foot 701 is consistent after bending.

[0048] During the processing of the foot 701 of the notebook radiator 7, when the foot 701 is bent after the radiator 7 is moved to the surface of the processing table 2, the radiator 7 is likely to move under the action of the bending, affecting the bending effect of the foot 701. As a further solution of the present invention, two pushing blocks 33 with inclined bottoms that pass through the limiting plate 6 are elastically and slidably connected to the limiting plate 6. The pushing blocks 33 are located at the front and rear sides of the radiator 7. A lower pressing plate 34 is elastically and slidably connected to the surface of the first cylinder 8. The lower pressing plate 34 is used to push the pushing blocks 33 downward when the first cylinder 8 moves downward.

[0049] During the processing of the foot 701 of the notebook radiator 7, the first cylinder 8 extends and drives the lower pressure plate 34 to move downward synchronously. Then, after the lower pressure plate 34 moves to the position of the pushing block 33, the lower pressure plate 34 can act to push the pushing block 33 to move downward. The pushing block 33 moves downward to the bottom of the limit plate 6 to squeeze and push the radiator 7 so that the front and rear positions of the radiator 7 can be fixed, thereby ensuring that the radiator 7 can remain stable when the foot 701 is bent subsequently, avoiding the position of the radiator 7 from shifting during the bending process of the foot 701, thereby affecting the bending effect of the foot 701. After the bending of the foot 701 is completed, the first cylinder 8 contracts and drives the lower pressure plate 34 to move upward, and the pushing block 33 can return to its original position under the action of the spring.

[0050] During the processing of the foot base 701 of the laptop radiator 7, the horizontal ends of the first cylinder 8 and the second cylinder 9 are not conducive to the bending of the foot base 701. The foot base 701 of the laptop radiator 7 is relatively thin and is easily cut when the first cylinder 8 or the second cylinder 9 is bent. As a further embodiment of the present invention, the ends of the first cylinder 8 and the second cylinder 9 are both inclined.

[0051] During the processing of the foot 701 of the notebook radiator 7, when the first cylinder 8 and the second cylinder 9 bend the foot 701, the inclined surface of the end of the first cylinder 8 and the second cylinder 9 away from the bending position first contacts the foot 701, and then the foot 701 is gradually pushed to an inclined state and fits with the end of the first cylinder 8 and the second cylinder 9. Finally, the first cylinder 8 and the second cylinder 9 continue to extend to bend the foot 701. The foot 701 can be pushed to an inclined state before being completely bent, so that there is a transition state when the foot 701 is bent, thereby ensuring the bending effect of the foot 701.

[0052] During the processing of the foot 701 of the laptop radiator 7, the distance between the limiting plate 6 and the processing table 2 cannot be adjusted, and radiators 7 of different thicknesses cannot be processed. As a further solution of the present invention, the connecting rod 5 is a telescopic rod, and the surface of the limiting plate 6 is rotatably connected to a threaded rod 35, which passes through the fixing plate 4 and is threadedly connected to the fixing plate 4;

[0053] During the processing of the foot 701 of the notebook radiator 7 , the height of the limiting plate 6 can be adjusted by the threaded rod 35 , so that radiators 7 of different thicknesses can be processed.

[0054] During the processing of the foot 701 of the notebook radiator 7, the blocking rod 10 needs to be fitted with the foot 701 so that the foot 701 in the fitted position is in a vertical state after being bent. The portion of the mounting plate 24 extending to the side of the blocking rod 10 near the foot 701 will affect the subsequent movement and removal of the foot 701. As a further solution of the present invention, the through groove 25 passes through the mounting plate 24 near the side of the foot 701.

[0055] During the processing of the foot 701 of the notebook radiator 7, the through groove 25 passes through the mounting plate 24 near the side of the foot 701, so that when the blocking rod 10 is in contact with the surface of the foot 701, the surface of the mounting plate 24 near the side of the foot 701 is parallel to the surface of the foot 701. Subsequently, when the radiator 7 is taken out after the foot 701 is bent, the foot 701 can be taken out along the side of the mounting plate 24, and the mounting plate 24 will not block the foot 701.
