Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor welding, in particular to a welding tool for semiconductors. Background Art

[0002] A semiconductor is a substance with an electrical conductivity between that of an insulator and that of a conductor. Its electrical conductivity is easily controlled and it can be used as a component material for information processing. Therefore, semiconductor materials are used in the manufacturing process of many electrical components. After components are made using semiconductor materials, they also need to be soldered on the corresponding circuit boards to achieve the desired effect.

[0003] During the welding process of traditional semiconductor components, the circuit board is fixed and clamped by a rigid clamp. If the strength is not well controlled, it is easy to damage the circuit board. In addition, during the welding process, repeated operations are required to achieve clamping and removal after loosening, which is troublesome to operate. In addition, during the welding process, smoke is generated, which will obstruct the line of sight and increase the difficulty of welding. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the circuit board is fixed and clamped by a rigid clamp, which is easy to damage the circuit board, and smoke is generated during the welding process, thereby obstructing the line of sight and increasing the difficulty of welding. The utility model provides a semiconductor welding tool.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A semiconductor welding tool comprises a support frame and a mounting plate, wherein the four corners of the bottom end of the mounting plate are fixedly mounted with the support frame, the mounting plate is stably placed by the support frame, a cylindrical platform is fixedly mounted through the middle of the mounting plate, a groove is provided at the top of the cylindrical platform, a slide groove is provided at the bottom of the groove at the top of the cylindrical platform, an extrusion block is slidably connected to the internal limit of the slide groove, a rack is fixedly connected to the bottom end of the extrusion block, a motor is fixedly mounted in the center of the cylindrical platform, a hydraulic coupler is fixedly mounted above the motor inside the cylindrical platform, a transmission shaft above the motor is transmission-connected to the hydraulic coupler, a rotating shaft is transmission-connected to the top end of the hydraulic coupler, a spiral toothed disk is fixedly mounted on the top end of the rotating shaft, the spiral toothed disk is rotationally connected inside the cylindrical platform, a torsion spring is fixedly mounted between the inside of the rotating shaft and the inner wall of the cylindrical platform, a fan blade is transmission-connected to the bottom end of the motor, an exhaust port is provided at the bottom of the cylindrical platform, and a smoking pipe is provided between the side of the groove inside the cylindrical platform and the top end face of the cavity where the fan blade is located.

[0007] Furthermore, there are four groups of combinations of the slide groove, extrusion block and rack, which are evenly distributed inside the cylindrical table. The bottom of the inner side of the extrusion block is provided with an inclined groove. Therefore, after the circuit board is placed, the circuit board can be stably limited in four directions through the contraction of the extrusion block. At the same time, the design of the groove can not only relatively clamp and fix the circuit board, but also make the circuit board close downward.

[0008] Furthermore, the hydraulic coupling is transmission-connected between the motor and the rotating shaft to realize a flexible transmission connection between the motor and the rotating shaft. Therefore, under the premise of not hindering the continuous rotation of the motor, a certain torque can be continuously given to the rotating shaft after the rotating shaft is no longer driven to rotate.

[0009] Furthermore, the top of the spiral toothed disc is in the shape of spiral teeth, and they are all meshed with the rack above, so that the rotation of the spiral toothed disc can drive the rack to shrink inward or expand outward at the same time.

[0010] Furthermore, when the fan blades rotate, the wind direction generated is downward, and the smoke pipe connects the groove with the cavity where the fan blades are located, and is evenly distributed inside the cylindrical table. Therefore, when the fan blades rotate, the smoke in the groove can be drawn downward through the smoke pipe and discharged downward from the exhaust port.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The utility model uses a motor to utilize a hydraulic coupler to connect the rotating shaft flexibly, and after the rotating shaft drives the spiral toothed disc to rotate, the extrusion block contracts to clamp and fix the circuit board, so that flexible clamping of the circuit board can be achieved, and the maximum clamping force is conveniently adjustable, thereby avoiding damage to the circuit board. After welding is completed, the motor stops rotating, and the limit on the circuit board can be released, making the clamping and removal of the circuit board more convenient.

[0013] 2. The utility model, through the rotation of the fan blade driven by the motor and the distribution of the smoke pipe, can extract the smoke generated by welding in the groove and discharge it downward from the exhaust port, so as to avoid the influence of the smoke on the welding line of sight and ensure the normal progress of welding.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] A semiconductor welding tool according to a preferred embodiment of the present invention will be described in detail below. Figure 1-7 As shown, a semiconductor welding tool comprises a support frame 1 and a mounting plate 2, the support frame 1 is fixedly installed at the four corners of the bottom end of the mounting plate 2, the mounting plate 2 is stably placed by the support frame 1, a cylindrical table 3 is fixedly installed through the middle of the mounting plate 2, a groove 4 is provided on the top of the cylindrical table 3, a slide groove 5 is provided at the bottom of the groove 4 at the top of the cylindrical table 3, the slide groove 5 is internally limited and slidably connected with an extrusion block 6, there are four groups of the combination of the slide groove 5, and they are evenly distributed inside the cylindrical table 3, the bottom of the inner side of the extrusion block 6 is provided with an inclined groove, so after the circuit board is placed, the circuit board can be stably limited in four directions by the contraction of the extrusion block 6, and at the same time, the design of the groove can be used to relatively clamp and fix the circuit board, and the circuit board can also be tightly attached downward.

[0024] A rack 7 is fixedly connected to the bottom end of the extrusion block 6, a motor 8 is fixedly installed in the center of the cylindrical table 3, a hydraulic coupler 9 is fixedly installed above the motor 8 inside the cylindrical table 3, a transmission shaft above the motor 8 is transmission-connected to the hydraulic coupler 9, and a rotating shaft 10 is transmission-connected to the top of the hydraulic coupler 9. The hydraulic coupler 9 is transmission-connected between the motor 8 and the rotating shaft 10 to achieve a flexible transmission connection between the motor 8 and the rotating shaft 10. Therefore, under the premise of not hindering the continuous rotation of the motor 8, after the rotating shaft 10 is no longer driven to rotate, a certain torque can be continuously given to the rotating shaft 10. A spiral toothed disk 11 is fixedly installed on the top of the rotating shaft 10, and the spiral toothed disk 11 is rotationally connected inside the cylindrical table 3. A torsion spring 12 is fixedly installed between the rotating shaft 10 and the inner wall of the cylindrical table 3. The top of the spiral toothed disk 11 is in the shape of spiral teeth, and they are all meshed with the rack 7 above, so that the rotation of the spiral toothed disk 11 can drive the rack 7 to shrink inward or expand outward at the same time.

[0025] The bottom end of the motor 8 is connected to the fan blade 13, and an exhaust port 14 is provided at the bottom of the cylindrical platform 3. A smoking pipe 15 is provided between the side of the groove 4 inside the cylindrical platform 3 and the top end face of the cavity where the fan blade 13 is located. When the fan blade 13 rotates, the wind direction generated is downward. The smoking pipe 15 connects the groove 4 with the cavity where the fan blade 13 is located, and is evenly distributed inside the cylindrical platform 3. Therefore, when the fan blade 13 rotates, the smoke in the groove 4 can be drawn downward through the smoking pipe 15 and discharged downward from the exhaust port 14.

[0026] The working principle of the utility model is:

[0027] When welding semiconductors, the circuit board to be welded is placed in the groove 4 at the top of the cylindrical table 3, and then the motor 8 is started, so that the motor 8 drives the rotating shaft 10 to rotate after passing through the hydraulic coupling 9, and then the rotating shaft 10 drives the spiral toothed disc 11 to rotate. During the rotation of the spiral toothed disc 11, the spiral teeth at the top of the spiral toothed disc 11 are engaged with the rack 7 at the bottom of the extrusion block 6, so that the extrusion block 6 can be driven to move inward in the slide groove 5 at the same time, so as to fix and clamp the placed circuit board. After reaching a certain clamping force, through the action of the hydraulic coupling 9, when the rotating shaft 10 no longer rotates, the motor 8 can still rotate normally and continue to give the rotating shaft 10 a certain torque to achieve stable clamping of the circuit board by the extrusion block 6, and the maximum clamping force can be adjusted by controlling the speed of the motor 8. After the welding is completed, the motor 8 stops working, and the rotating shaft 10 will reverse under the action of the restoring force of the torsion spring 12, thereby driving the spiral toothed disc 11 to reverse, so that the extrusion block 6 is expanded outward, and the limit on the circuit board is released, so as to facilitate the removal of the circuit board after welding.

[0028] When the motor 8 is used to achieve clamping, the fan blade 13 is also driven to rotate and blow air downward, so that the smoke generated by welding in the groove 4 can be extracted through the smoke pipe 15 and discharged downward from the exhaust port 14 to avoid the influence of the smoke on the welding line of sight and ensure the normal progress of welding.

[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
