[0024] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0025] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0026] As Figures 1 - 4 shown, an embodiment of the present invention provides a MOSFET chip welding device, including a welding assembly 1. The welding assembly 1 includes an operating table 11, a bracket 12, a chute 13, a first slider 14, a mounting frame 15, a second slider 16, a lifting electric cylinder 17, a heating element 18, a welding head 19, a temperature sensor 20, a mounting ring 21, a camera 22, a through groove 23, a controller 24, and an image processing module 25;

[0027] On both sides of the upper surface of the operating table 11, there are fixedly connected brackets 12. In the middle of the upper surface of the bracket 12, there is a chute 13. The inner side wall of the chute 13 is slidably connected with a first slider 14. The bottom of the first slider 14 is fixedly connected with a mounting frame 15.

In the middle of the outer side wall of the welding head 19, there is a temperature sensor 20. The lower part of the outer side wall of the heating element 18 is fixedly connected with a camera 22 through a mounting ring 21. In the front part of the upper surface of the operating table 11, there is a through groove 23. The inner side wall of the through groove 23 is fixedly connected with a controller 24.

If an abnormal situation occurs, the controller 24 can take remedial measures in time or stop welding.

[0028] In one embodiment, specifically: In the middle of the upper surface of the operating table 11, there is a limit groove 26. In the middle of the inner bottom wall of the limit groove 26, there is a heat dissipation port 27. The inner side wall of the limit groove 26 is closely connected with a welding table 28. In the middle of the upper surface of the welding table 28, there is a placement groove 29. The inner bottom wall of the placement groove 29 is fixedly connected with an anti-slip pad 30. Both the inner bottom wall of the placement groove 29 and the upper surface of the anti-slip pad 30 are provided with a plurality of heat dissipation holes 31.

The heat generated during the welding process is dissipated through the welding table 28, the anti-slip pad 30, and the heat dissipation ports 27 and heat dissipation holes 31 on the operating table 11 to ensure that the temperature of the welding device and the chip is within a safe range.

[0029] In one embodiment, specifically: a first screw rod 33 passes through the upper part of one side of the bracket 12.

By the threaded connection between the first screw rod 33 and the first screw hole 35 on the first slider 14, when the lateral adjustment motor 34 drives the first screw rod 33 to rotate, the first slider 14 is driven to move left and right.

[0030] In one embodiment, specifically: a second screw rod 36 passes through the center of the front surface of the mounting frame 15. A longitudinal adjustment motor 37 is fixedly connected to the outer side of the front surface of the mounting frame 15 near the second screw rod 36. The front surface of the second screw rod 36 is fixedly connected to the output end of the longitudinal adjustment motor 37. A second screw hole 38 is formed at the center of the front surface of the second slider 16. The inner side wall of the second screw hole 38 is threadedly connected to the inner side wall of the second screw rod 36. The input end of the longitudinal adjustment motor 37 is electrically connected to the output end of the controller 24. By the threaded connection between the second screw rod 36 and the second screw hole 38 on the second slider 16, when the longitudinal adjustment motor 37 drives the second screw rod 36 to rotate, the second slider 16 is driven to move back and forth.

[0031] In one embodiment, specifically: first limiting grooves 39 are formed in the middle of the inner front wall and the inner rear wall of the sliding groove 13. First limiting blocks 40 are fixedly connected to the middle of the front surface and the rear surface of the first slider 14. The outer side wall of the first limiting block 40 is slidably connected to the inner side wall of the first limiting groove 39. By the first limiting block 40 on the first slider 14 sliding inside the first limiting groove 39, the first limiting block 40 is limited, thereby increasing the stability of the sliding of the first slider 14.

[0032] In one embodiment, specifically: second limiting grooves 41 are formed on both sides of the inner side wall of the mounting frame 15. Second limiting blocks 42 are fixedly connected to the middle of both sides of the second slider 16. The outer side wall of the second limiting block 42 is slidably connected to the inner side wall of the second limiting groove 41. By the second limiting block 42 on the second slider 16 sliding inside the second limiting groove 41, the second slider 16 is limited, thereby increasing the stability of the sliding of the second slider 16.

[0033] In one embodiment, specifically: a touch screen 43 is arranged on the upper surface of the controller 24. Through the touch screen 43, it is convenient to set welding parameters and observe welding quality, etc.

[0034] In one embodiment, specifically: Support legs 44 are fixedly connected to the four corners of the bottom of the operating table 11. By supporting the operating table 11 through the support legs 44, the stability of the entire device is increased.

[0035] When the present utility model is working: The MOSEFT chip to be welded is placed in the placement groove 29 of the welding table 28. The anti-slip pad 30 ensures that the chip does not slide during the welding process. Welding parameters such as welding temperature and welding time are set through the touch screen 43 on the operating table 11. These parameters will be input into the controller 24. The horizontal adjustment motor 34 is started, and the first slider 14 is driven by the first screw rod 33 to move left and right in the sliding groove 13, thereby adjusting the horizontal position of the welding head 19 left and right. At the same time, the vertical adjustment motor 37 is started, and the second slider 16 is driven by the second screw rod 36 to move back and forth in the mounting frame 15, so that the welding head 19 is aligned with the welding point on the chip. The controller 24 controls the lifting electric cylinder 17 to start according to the preset welding parameters, so that the heating element 18 and the welding head 19 descend close to the chip surface. The heating element 18 starts to heat, and the heat is transferred to the chip and the solder through the welding head 19, and the welding process starts. The temperature sensor 20 monitors the temperature of the welding area in real time and transmits the data to the controller 24. The controller 24 adjusts the heating power of the heating element 18 according to the temperature data to ensure that the welding temperature is maintained within the set range. The camera 22 takes an image of the welding area, analyzes it through the image processing module 25, identifies the welding state (such as whether there is poor welding, whether the solder joints are uniform, etc.), and feeds back the analysis result to the controller 24. If an abnormal situation occurs, the controller 24 can take remedial measures in time or stop the welding. After the welding is completed, the lifting electric cylinder 17 drives the heating element 18 and the welding head 19 to rise and leave the chip surface. The operator can conveniently pick up and place the welded chip or place a new chip for welding through the pick-and-place groove 32 on the operating table 11.

[0036] As described above, only the specific embodiments of the present utility model are provided, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
