Description

Technical Field

[0001] This utility model relates to the field of transistor processing technology, specifically a transistor and heat sink locking device. Background Technology

[0002] Transistors are important electronic components in circuit chips. A transistor can be regarded as a switch, and the output voltage can be determined by controlling their switching. When current passes through a transistor, it releases some heat, just like an electric heater in life. At the same time, since the heat dissipation rate is much smaller than the heat generation rate, a local high temperature area is formed. Therefore, the heat dissipation problem of transistors is also a problem that people urgently need to solve.

[0003] In existing technologies, transistors are typically mounted together with heat sinks to improve their heat dissipation efficiency. Currently, mounting transistors and heat sinks relies entirely on manual operation, where operators use tools to fix the transistors and heat sinks together with screws. However, manual mounting of transistors and heat sinks is very inefficient and makes it difficult to meet short-term batch component demand. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a transistor and heat sink locking device, including a processing table, and an automatic locking mechanism is provided on the top of the processing table;

[0006] The automatic locking mechanism includes an L-shaped plate, which is fixedly connected to the upper middle part of the front and rear walls of the processing table. A clamping cylinder is fixedly connected to the middle part of the side wall of the L-shaped plate away from the processing table. A U-shaped plate is fixedly connected to the top between the two sets of L-shaped plates. A lifting cylinder is fixedly connected to the front and rear sides of the top of the U-shaped plate. The output ends of the lifting cylinders are fixedly connected to the front and rear ends of the middle part of the top wall of the connecting plate. A drive motor is fixedly connected to the middle part of the top wall of the connecting plate. A screwdriver is fixedly connected to the output end of the drive motor. Multiple sets of evenly distributed baffles are fixedly connected to the outer surface of the belt conveyor.

[0007] As a preferred embodiment of this utility model, a belt conveyor is provided in the middle of the top wall of the processing table, and multiple sets of evenly distributed heat sink bodies are provided on the surface of the belt conveyor.

[0008] As a preferred embodiment of this utility model, a transistor body is provided on the inner side of the heat sink body, and a locking nut is provided in the middle of the transistor body.

[0009] As a preferred embodiment of this utility model, the output end of the clamping cylinder is located on the front and rear sides of the heat sink body, and the screwdriver and the locking nut are on the same vertical horizontal line.

[0010] As a preferred embodiment of this utility model, a mounting plate is fixedly connected to the left side of the front wall of the processing table, and a rotating shaft is rotatably connected through the middle of the mounting plate.

[0011] As a preferred technical solution of this utility model, the bottom end of the rotating shaft is fixedly connected to a base plate, the top outer side of the base plate is fixedly connected to a torsion spring, and the top end of the torsion spring is fixedly connected to the outer side of the middle part of the bottom wall of the mounting plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. This transistor and heat sink locking device, when the transistor and heat sink need to be installed, combines the two and places them on the surface of a belt conveyor. The belt conveyor is started to transport the heat sink and transistor. During the transport process, the heat sink contacts the detection plate and applies a pushing force to the detection plate, causing the detection plate to drive the rotating shaft to rotate. During the rotation of the shaft, the toggle plate rotates and presses the control switch, thereby making the automatic locking mechanism on the right side work, eliminating the manual control link and improving the locking efficiency;

[0015] 2. This transistor and heatsink locking device uses two sets of clamping cylinders to clamp and fix the heatsink during the operation of the automatic locking mechanism. At the same time, the lifting cylinder moves the connecting plate and the drive motor downward. After inserting the screwdriver into the top of the corresponding locking nut, the drive motor is started. During the rotation of the drive motor, the screwdriver rotates, and the connecting plate moves downward to automatically lock the transistor and heatsink, further improving the locking efficiency.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1-4 As shown, the present invention provides a transistor and heat sink locking device, including a processing table 1, and an automatic locking mechanism 2 is provided on the top of the processing table 1;

[0024] The automatic locking mechanism 2 includes an L-shaped plate 14, which is fixedly connected to the upper middle part of the front and rear walls of the processing table 1. A clamping cylinder 15 is fixedly connected to the middle part of the side wall of the L-shaped plate 14 away from the processing table 1. The L-shaped plate 14 provides space for the installation of the clamping cylinder 15 and the U-shaped plate 16. A U-shaped plate 16 is fixedly connected to the top between the two sets of L-shaped plates 14. Lifting cylinders 17 are fixedly connected to the front and rear sides of the top of the U-shaped plate 16. The operation of the lifting cylinder 17 can drive the connecting plate 18 to move up and down. The output end of the lifting cylinder 17 is fixedly connected to the front and rear ends of the middle part of the top wall of the connecting plate 18. A drive motor 19 is fixedly connected to the middle part of the top wall of the connecting plate 18. A screwdriver 20 is fixedly connected to the output end of the drive motor 19. The operation of the drive motor 19 can make the screwdriver 20 rotate, thereby locking the locking nut 6 to the transistor body 5 and the heat sink body 4.

[0025] A belt conveyor 3 is installed in the middle of the top wall of the processing table 1. Multiple sets of evenly distributed heat sink bodies 4 are installed on the surface of the belt conveyor 3. Multiple sets of evenly distributed baffles 21 are fixedly connected to the outer surface of the belt conveyor 3. A transistor body 5 is installed on the inner side of each heat sink body 4. A locking nut 6 is installed in the middle of the transistor body 5. The locking nut 6 is threadedly connected to the heat sink body 4. During rotation, the locking nut 6 will move downward.

[0026] The output ends of the clamping cylinder 15 are located on the front and rear sides of the heat sink body 4, respectively. The screwdriver 20 and the locking nut 6 are on the same vertical horizontal line. The mounting plate 7 is fixedly connected to the left side of the front wall of the processing table 1. The mounting plate 7 has a rotating shaft 8 that runs through and rotates through the middle of the mounting plate 7. The rotation of the rotating shaft 8 causes the toggle plate 9 to rotate. During the rotation of the toggle plate 9, the control switch 13 can be pressed, thereby controlling the automatic locking mechanism 2.

[0027] A base plate 11 is fixedly connected to the bottom end of the rotating shaft 8. A torsion spring 12 is fixedly connected to the outer top of the base plate 11. The top of the torsion spring 12 is fixedly connected to the outer middle of the bottom wall of the mounting plate 7. A control switch 13 is provided on the right side of the top wall of the mounting plate 7. A toggle plate 9 is fixedly connected to the middle right side of the outer periphery of the rotating shaft 8. A detection plate 10 is fixedly connected to the top of the rear side of the outer periphery of the rotating shaft 8. The torsion spring 12 can automatically reset the rotating shaft 8, thereby allowing the detection plate 10 to return to its position for the next detection operation.

[0028] Working principle: When it is necessary to install the transistor and heat sink, the two are combined and placed on the surface of the belt conveyor 3. The belt conveyor 3 is started to transport the heat sink and transistor. During the transport process, the heat sink contacts the detection plate 10 and applies a pushing force to the detection plate 10, causing the detection plate 10 to drive the rotating shaft 8 to rotate. During the rotation of the rotating shaft 8, the toggle plate 9 rotates and presses the control switch 13, thereby making the automatic locking mechanism 2 on the right side work, eliminating the manual control link. During the operation of the automatic locking mechanism 2, the two sets of clamping cylinders 15 work to clamp and fix the heat sink. At the same time, the lifting cylinder 17 works to move the connecting plate 18 and the drive motor 19 downward. After inserting the screwdriver 20 into the top of the corresponding locking nut 6, the drive motor 19 is started. During the rotation of the drive motor 19, the screwdriver 20 rotates, and at the same time the connecting plate 18 moves downward to realize the automatic locking of the transistor and heat sink.
