Description

Technical Field

[0001] This utility model relates to the field of integrated circuit manufacturing technology, and more specifically, to a welding device for integrated circuits. Background Technology

[0002] Integrated circuits are the "brains" of electronic devices. They consist of a large number of tiny transistors, resistors, capacitors and other components. These components need to be connected to the circuit board by soldering in order to realize the circuit function.

[0003] In existing technologies, integrated circuits come in various sizes (such as chips and circuit boards of different specifications). If the fixing structure cannot be adjusted, special fixing devices need to be customized for different sizes, which increases equipment costs. Moreover, frequent replacements are required when switching, which affects welding efficiency. Integrated circuit components are fragile and have precise pins. If the clamping force is not properly controlled, it can easily lead to component deformation and pin damage. If the clamping is not firm, the integrated circuit will shift during welding, which will cause poor soldering and missing solder, affecting the welding quality. Utility Model Content

[0006] The present invention is further configured such that a fixing rod is rotatably provided on the fixing box, a first bevel gear is fixedly provided on the fixing rod inside the fixing box, and a second bevel gear is provided on the fixing screw to cooperate with the first bevel gear. The cooperation of the first bevel gear and the second bevel gear facilitates the rotation of the fixing screw.

[0007] The present invention is further configured such that a fixed motor is provided at the bottom of the fixed base, a first gear is provided on the motor shaft of the fixed motor, and a second gear is provided on the fixed rod to cooperate with the first gear, so as to facilitate the rotation of the fixed rod.

[0008] The present invention is further provided with cover plates on both sides of the fixing block to prevent welding slag from falling onto the fixing screw.

[0009] The present invention is further configured such that the moving block is provided with an adjusting rod, the adjusting rod is slidably disposed on the clamping sleeve, and the clamping sleeve is threadedly connected to an adjusting sleeve, the moving block is driven to move by the cooperation of the adjusting sleeve and the adjusting rod.

[0010] The present invention is further configured such that the adjusting rod is provided with an adjusting block, and the adjusting sleeve is provided with an adjusting groove that cooperates with the adjusting block, so that the adjusting rod can be moved by the adjusting sleeve.

[0011] The present invention is further configured such that a moving spring is provided between the moving groove and the moving block, which improves the thread engagement force of the adjusting sleeve and the clamping sleeve.

[0012] The present invention is further configured such that a sliding block is provided on the clamping plate, and a sliding groove is provided on the clamping sleeve to cooperate with the sliding block, thereby restricting the movement direction of the clamping plate.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a welding device for integrated circuits, which has the following advantages: 1. Start the fixed motor, which drives the fixed screw to rotate through gear and bevel gear transmission, causing the fixed block to move along the fixed groove, thereby adjusting the clamping device spacing to adapt to the fixing requirements of integrated circuits of different sizes. There is no need to replace the fixing device. One set of equipment can meet the fixing of integrated circuits of various sizes, reduce equipment costs, reduce adjustment time when changing sizes, and improve welding efficiency.

[0014] 2. Rotating the adjusting sleeve can drive the moving block to move. Through the cooperation of the inclined groove and the moving rod, the clamping rod drives the clamping plate to smoothly clamp the integrated circuit. The clamping pad can buffer the clamping force to avoid damage to the components and pins. The moving spring provides continuous elasticity to ensure that the clamping plate is always firmly clamped and prevents displacement during welding. This not only ensures clamping stability but also avoids damage to the integrated circuit, improving welding quality and component qualification rate. Attached Figure Description
