[0017] In the above solution of the present invention, two radiator positioning mechanisms 4 are sequentially arranged along the conveying direction of the horizontal conveying device 1, and are respectively the first radiator positioning mechanism and the second radiator positioning mechanism.

[0018] The present invention adopts the above solution and uses an assembly device to assemble the power amplifier board 100 and the heat sink 200. The specific process is as follows: The power amplifier board 100 to be assembled is placed in the power amplifier board positioning frame 11 of the pressing device 2, so that the power amplifier board 100 is located below the pressing plate 21, and the two ends of the power amplifier board 100 are respectively embedded in the power amplifier board positioning grooves of the power amplifier board positioning part 15, so as to position the power amplifier board 100, and the pressing device 2 with the power amplifier board 100 to be assembled is driven to move by the horizontal conveying device 1, so that the two pressing devices 2 are respectively located directly above the two heat sink positioning mechanisms 4; The radiator 200 to be assembled is placed on the radiator positioning plate 7 of the first radiator positioning mechanism, and the bottom of the radiator 200 is embedded in the radiator positioning groove 8 of the radiator positioning plate 7, so as to position the radiator 200, and the top surface of the radiator 200 on the first radiator positioning mechanism is coated with glue by the glue dispensing mechanism 5. After completion, the radiator 200 to be assembled is placed on the radiator positioning plate 7 of the second radiator positioning mechanism, and the rotating mechanism drives the glue dispensing mechanism 5 to transfer from the top of the first radiator positioning mechanism to the top of the second radiator positioning mechanism. At this time, the top surface of the radiator 200 on the second radiator positioning mechanism is coated with glue by the glue dispensing mechanism 5, and at the same time, the lifting mechanism drives the lifting of the first radiator positioning mechanism. The seat 6 moves upward a set distance, and the lifting seat 6 drives the radiator positioning plate 7 and the radiator 200 to move upward together. During this process, the radiator positioning plate 7 will drive the radiator 200 to pass through between the power amplifier board positioning parts 15 of the two sliders 12 and then contact the power amplifier board 100, and push the power amplifier board 100 to move upward together. When the power amplifier board 100 moves upward, it will contact the pressing plate 21, and push the pressing plate 22 upward to compress the vertical pressing spring 24, so that the pressing plate 21 presses and assembles the power amplifier board 100 and the radiator 200 under the elastic force of the vertical pressing spring 24. When the radiator 200 moves upward to the top of the power amplifier board positioning part 15, the driving inclined surface 10 of the inserting knife 9 will contact the driven inclined surface 14 of the slider 12, and through the driving inclined surface 1 0 contacts and cooperates with the driven inclined surface 14, driving the slider 12 to move toward the amplifier board positioning frame 11 and stretching the horizontal return spring 16, so that the slider 12 drives the amplifier board positioning portion 15 to move to the bottom of the radiator 200, until the slider 12 moves to the lock hole corresponding to the lock pin 18, the lock pin 18 will move downward under the elastic force of the vertical tension spring 20 and be inserted into the lock hole, thereby locking the slider 12 in the current position, and after completion, the lifting seat 6 and the radiator positioning plate 7 of the first radiator positioning mechanism are driven downward and reset by the lifting mechanism. At this time, the radiator 200 will be blocked by the amplifier board positioning portion 15 and remain in the amplifier board positioning frame 11, and the amplifier board positioning portion 15 supports the bottom of the radiator 200, and the pressing plate 21 is pressed by the vertical pressing spring The elastic force of the spring 24 maintains the pressing effect on the power amplifier board 100 and the radiator 200. When the first radiator positioning mechanism is reset, the radiator 200 on the second radiator positioning mechanism has been glued, and then the glue dispensing mechanism 5 is driven by the rotating mechanism to return from the top of the second radiator positioning mechanism to the top of the first radiator positioning mechanism, and the radiator 200 to be assembled is placed on the radiator positioning plate 7 of the first radiator positioning mechanism again and glued by the glue dispensing mechanism 5. At the same time, the lifting seat 6 of the second radiator positioning mechanism is driven upward by the lifting mechanism and the above-mentioned pressing operation is repeated. After completion, the pressing device 2 is driven by the horizontal conveying device 1 to move a set distance, so that the pressing device 2 that has completed the assembly operation is removed from the top of the radiator positioning mechanism 4.The other two pressing devices 2 with the amplifier boards 100 to be assembled are respectively located directly above the two radiator positioning mechanisms 4, and the above operation is repeated. When the horizontal conveying device 1 drives the assembled pressing device 2 to move to the designated location, the pressing plate 21 is driven upward by pulling the pull block 23, and the assembled amplifier board 100 and radiator 200 can be taken out. After the locking pin 18 is pulled out of the lock hole, the slider 12 can be reset under the elastic force of the horizontal reset spring 16. During the use of the assembly equipment of the present invention, the pressing operation can be carried out while the glue dispensing mechanism 5 is operating, and during the conveying process of the horizontal conveying device 1, the power amplifier board 100 and the radiator 200 can be pressed for a long time to ensure the pressing quality. At the same time, the thermal conductive glue between the power amplifier board 100 and the radiator 200 can be naturally cooled and fixed before being conveyed to the designated location, which saves the waiting time between the processes and is conducive to improving the assembly efficiency.

[0019] Furthermore, the pressing plate 21 is a frame-shaped plate. By adopting the above solution, the pressing plate 21 can avoid the electronic components on the power amplifier board 100.

[0020] Furthermore, the lifting mechanism includes a hydraulic cylinder 25 , which is disposed below the workbench 3 , and an output shaft of the hydraulic cylinder 25 passes through the workbench 3 upward and is connected to the lifting seat 6 .

[0021] Furthermore, the rotating mechanism includes a motor 26, a rotating column 27 and a mounting plate 28. The rotating column 27 is rotatably arranged on the top of the workbench 3, one end of the mounting plate 28 is connected to the rotating column 27, and the dispensing mechanism 5 is connected to the other end of the mounting plate 28. The motor 26 is arranged below the workbench 3, and the output shaft of the motor 26 passes through the workbench 3 upward and is connected to the rotating column 27.

[0022] Furthermore, the motor 26 is a servo motor.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
