The inner wall of the first slider 203 is slidably connected to the outer wall of a first slide rail 204, and the first slide rail 204 is detachably connected to the upper surface of the support plate 101. The operation of the first electric cylinder 201 drives the first pneumatic telescopic rod 202 to slide, thereby driving the first slider 203 to slide linearly along the first slide rail 204, which in turn drives the connecting plate 301 and the bearing plate 303 to move linearly to the position below the suction cup 702.

[0029] Specifically, the heat sink support assembly 3 includes a connecting plate 301, which is detachably connected to the upper surface of the first slider 203.

The outer side wall of the connecting plate 301 is provided with a handle 304. By placing the aluminum-magnesium alloy heat sink to be bent along the support groove 305 and then gripping the handle 304 to move the support plate 303 into the connecting groove 302, the support plate 303 and the connecting plate 301 can be engaged, thereby placing the aluminum-magnesium alloy heat sink to be bent on the upper surface of the first slider 203.

[0030] Specifically, the heat sink lifting assembly 4 includes a right-angle plate 401, which is detachably connected to the outer wall of the bottom surface of the support plate 101.

A top rod 405 is provided on the upper surface of the top plate 404. The outer wall of the top rod 405 is engaged with the inner wall of the bearing groove 305. The second electric cylinder 402 drives the second pneumatic telescopic rod 403 to slide, thereby driving the top plate 404 to move linearly. This, in turn, drives the top rod 405 to slide along the inner wall of the bearing groove 305 and raises the vertical height of the aluminum-magnesium alloy heat sink to be bent.

[0031] Specifically, the first linear drive assembly 5 includes a support frame 501, which is detachably connected to the upper surface of the support plate 101. A servo motor 502 is detachably connected to the outer wall of the support frame 501. The output shaft of the servo motor 502 is connected to a lead screw 503. A ball nut 504 is provided on the outer wall of the lead screw 503. A side block 505 is detachably connected to the outer wall of the ball nut 504. A second slider 507 is detachably connected to the outer wall of the side block 505 facing the support frame 501. The outer wall of the support frame 501 is detachably connected to... The second slide rail 506 is connected to the unscrewed part. The inner wall of the second slider 507 is slidably connected to the outer wall of the second slide rail 506. The servo motor 502 drives the lead screw 503 to rotate, which in turn drives the ball nut 504 to rotate. Then, under the action of the second slider 507 sliding along the second slide rail 506, the aluminum-magnesium alloy heat sink to be bent, which is adsorbed by the side block 505 and the suction cup 702, can be linearly moved to the position above the external limiting plate. Then, under the action of the second linear drive component 6, the aluminum-magnesium alloy heat sink to be bent can be wedged into the inner wall of the external limiting groove.

[0032] Specifically, the second linear drive assembly 6 includes a third electric cylinder 601, which is detachably connected to the outer surface of the side block 505. One end of a third pneumatic telescopic rod 602 is slidably connected to the inner wall of the third electric cylinder 601, and the other end of the third pneumatic telescopic rod 602 is detachably connected to a horizontal plate 603. A fourth electric cylinder 604 is detachably connected to the outer wall of the horizontal plate 603, and one end of a fourth pneumatic telescopic rod 605 is slidably connected to the inner wall of the fourth electric cylinder 604, and the other end of the fourth pneumatic telescopic rod 605 is detachably connected to a connecting block 606. The operation of the third electric cylinder 601 drives the third pneumatic telescopic rod 602 to extend and slide, thereby driving the horizontal plate 603 to move linearly, which in turn drives the horizontal plate 603 to linearly move towards the aluminum-magnesium alloy heat sink to be bent. The operation of the fourth electric cylinder 604 drives the fourth pneumatic telescopic rod 605 to extend and slide, thereby driving the clamping plate 701 to move towards the aluminum-magnesium alloy heat sink to be bent.

[0033] Specifically, the heat sink adsorption assembly 7 includes a card plate 701, the upper surface of which is detachably connected to the outer wall of the bottom surface of the connecting block 606, and a suction cup 702 detachably connected to the outer wall of the bottom surface of the card plate 701. The suction cup 702 is used to adsorb the aluminum-magnesium alloy heat sink to be bent that is carried inside the bearing groove 305. The aluminum-magnesium alloy heat sink to be bent can be adsorbed by the suction cup 702 and with the cooperation of an external air pump.

[0034] Specifically, there are two heat sink support components 3, and the two heat sink support components 3 are evenly distributed on the upper surface of the first slider 203. The two heat sink support components 3 enable the other heat sink support component 3 to load and unload heat sink components while one heat sink support component is carrying heat sink components.

[0035] Specifically, there are multiple suction cups 702, and the multiple suction cups 702 are evenly distributed on the outer wall of the bottom surface of the card plate 701. The multiple suction cups 702 enable the card plate 701 to perform a large-scale transfer function of heat dissipation components in a single movement.

[0036] In use, first, place the aluminum-magnesium alloy heat sink to be bent along the bearing groove 305. Then, grip the handle 304 and move the bearing plate 303 into the connecting groove 302 to engage the bearing plate 303 with the connecting plate 301. This allows the aluminum-magnesium alloy heat sink to be bent to be placed on the upper surface of the first slider 203. Next, the first electric cylinder 201 drives the first pneumatic telescopic rod 202 to slide, causing the first slider 203 to slide linearly along the first slide rail 204. This causes the connecting plate 301 and the bearing plate 303 to move linearly to a position below the suction cup 702. Then, the second electric cylinder 402 drives the second pneumatic telescopic rod 202 to slide. The sliding of the retracting rod 403 causes the top plate 404 to move linearly, which in turn causes the top rod 405 to slide along the inner wall of the bearing groove 305 and raise the vertical height of the aluminum-magnesium alloy heat sink to be bent. This effectively enables the device to automatically move the aluminum-magnesium alloy heat sink to be bent to a position below the suction cup 702. Furthermore, the two heat sink bearing components 3 allow one component to support the heat sink while the other loads and unloads it. The heat sink lifting component 4 automatically lifts the uppermost heat sink to the required height during the bending process. This process not only increases the feeding speed of the heat sink components but also reduces the workload of the workers. Then, the third electric cylinder 601 drives the third pneumatic telescopic rod 602 to extend and slide, thereby causing the horizontal plate 603 to move linearly. This allows the horizontal plate 603 to linearly approach the aluminum-magnesium alloy heat sink component to be bent. Next, the fourth electric cylinder 604 drives the fourth pneumatic telescopic rod 605 to extend and slide, thereby causing the clamping plate 701 to approach the aluminum-magnesium alloy heat sink component to be bent. Then, with the assistance of the suction cup 702 and an external air pump, the aluminum-magnesium alloy heat sink component to be bent is adsorbed. Finally, the servo motor 502 drives the lead screw 503 to rotate from... The ball nut 504 can rotate, and under the cooperation of the second slider 507 sliding along the second slide rail 506, the aluminum-magnesium alloy heat sink to be bent, which is adsorbed by the side block 505 and the suction cup 702, can be linearly moved to the position above the external limiting plate. Then, under the cooperation of the second linear drive component 6, the aluminum-magnesium alloy heat sink to be bent can be wedged into the inner wall of the external limiting groove. This effectively realizes the function of automatically adsorbing and transporting the aluminum-magnesium alloy heat sink to be bent to the required position. Moreover, no manual intervention is required in the entire transport process, which not only increases the transport efficiency of the heat sink, but also reduces the risk of damage to the heat sink during the transport process.
