Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of welding equipment technology, and specifically to a welding device for the production of MOSFET devices. Background Technology
[0002] In the field of modern electronic equipment manufacturing, MOSFET devices, as key electronic components, are widely used in various electronic products. The soldering quality of MOSFETs directly affects the performance, stability, and reliability of electronic products.
[0003] Traditional MOSFET device soldering methods primarily employ manual soldering or simple semi-automatic soldering equipment. In manual soldering, the varying skill and experience levels of workers make it difficult to guarantee consistent soldering quality. Furthermore, manual operation is susceptible to fatigue and emotional factors, leading to problems such as incomplete soldering, short circuits, and soldering misalignment. These issues not only increase the defect rate and production costs but may also cause product malfunctions during subsequent use, negatively impacting user experience and product reputation.
[0004] While semi-automatic welding equipment improves welding efficiency to some extent, its functions are relatively limited and its flexibility is insufficient. For example, it often fails to meet the needs of circuit boards of different specifications and shapes, as well as diverse welding process requirements. They typically can only perform simple straight-line welding or fixed-angle welding operations. For complex circuit boards requiring precise welding at multiple angles and positions, they cannot accurately adjust the welding position and angle, thus limiting their application in high-end electronic product manufacturing.
[0005] Furthermore, as electronic products become increasingly miniaturized and multifunctional, higher demands are placed on the soldering precision and efficiency of MOSFET devices. Traditional soldering techniques are proving increasingly inadequate when faced with increasingly sophisticated circuit board layouts and smaller MOSFET devices. To meet the demands of the modern electronics manufacturing industry for high-quality, high-efficiency soldering, the development of a highly automated and stable soldering device capable of flexibly adjusting the soldering position and angle is urgently needed.

[0007] This invention provides a welding apparatus for the production of MOSFET devices, thereby solving the technical problems existing in the background art.
[0008] 2. Technical Solution:

[0015] 3. Beneficial effects:
[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:
[0017] This invention enables the circuit board to be angled within a certain range through an angle adjustment mechanism, meeting diverse welding angle requirements. For MOSFET devices that require side welding, adjusting the circuit board to a suitable tilt angle via the angle adjustment mechanism makes it easier for the welding head to approach the welding area, improving welding accuracy and quality.
[0018] This invention utilizes a combination of a lateral movement mechanism and a lifting mechanism to precisely adjust the position of the welding mechanism in both the horizontal and vertical directions within a plane. This allows the welding mechanism to accurately reach the desired location on the circuit board for welding, regardless of the MOSFET device's position, thus enabling welding at different locations on the circuit board and significantly improving the versatility and applicability of the welding device.
[0019] This invention features multi-axis adjustment functions, including lateral, longitudinal, and angular adjustments. This multi-axis adjustment capability allows for more flexible and precise adjustment of the welding position and angle. Compared to traditional welding devices, it can adapt to more complex welding processes and circuit board designs, significantly improving welding quality.
[0020] The clamping mechanism of this invention, through components such as a clamping plate, a clamping block, and a clamping cylinder, can firmly clamp the circuit board. The placement slot initially positions the circuit board, and the clamping block, under the action of the clamping cylinder, clamps the circuit board, ensuring that the circuit board does not shift during the entire soldering process, thus guaranteeing high-quality soldering.
[0021] This invention achieves a high degree of automation in its welding device through the control of automated components such as a horizontal linear module, a lifting linear module, and a clamping cylinder. During the welding process, operators only need to perform simple parameter settings and start the machine; the equipment can automatically complete a series of actions, including angle adjustment, position adjustment, and circuit board clamping, reducing manual operation. This not only improves production efficiency but also reduces welding quality problems caused by human error, while also reducing labor intensity and allowing operators to complete their work more easily.

[0036] See attached document Figures 1-7 A welding apparatus for MOSFET device production includes a base 1, a frame 2 mounted on the base 1, a transverse mechanism 3 mounted on the frame 2, a lifting mechanism 4 mounted on the output end of the transverse mechanism 3, a welding mechanism 5 mounted on the output end of the lifting mechanism 4, an angle adjustment mechanism 7 mounted on the base 1, a clamping mechanism 6 mounted on the output end of the angle adjustment mechanism 7, the clamping mechanism 6 being used to clamp a circuit board, and the welding mechanism 5 being positioned above the clamping mechanism 6.
[0037] The transverse mechanism 3 includes a transverse linear module 31 and a guide rail 33 arranged parallel to the frame 2. A slider 34 is slidably mounted on the guide rail 33. A mounting bracket 32 is provided on the output end of the transverse linear module 31. The other end of the mounting bracket 32 is fixed on the slider 34. The lifting mechanism 4 is fixed on the mounting bracket 32.
[0038] The lifting mechanism 4 includes a transverse plate 41 fixed on the mounting frame 32, a lifting linear module 42 fixedly installed on the transverse plate 41, a lifting block 43 provided on the output end of the lifting linear module 42, and a welding mechanism 5 provided on the lifting block 43.
[0039] The angle adjustment mechanism 7 includes a support frame 71, a drive shaft 72 is rotatably mounted on the lower end of the support frame 71, two adjustment shafts 73 are rotatably mounted on the upper part of the support frame 71, the two adjustment shafts 73 are symmetrically arranged on both sides of the support frame 71, a synchronous belt assembly 74 is provided at each end of the drive shaft 72, and the other end of each synchronous belt assembly 74 is connected to an adjustment shaft 73, and a motor 75 is provided at one end of the drive shaft 72.
[0040] The clamping mechanism 6 includes a mounting block 61 fixed on the adjusting shaft 73. The two mounting blocks 61 are symmetrically arranged, and a clamping plate 62 is fixedly installed between the two mounting blocks 61. The clamping plate 62 has a placement slot 63 for placing the circuit board. Two clamping cylinders 65 are symmetrically arranged at the lower end of the clamping plate 62. The output end of the clamping cylinder 65 is connected to the clamping block 64.
[0041] The output end of the clamping cylinder 65 is connected to the clamping block 64 through the connecting block 66. A second slider 68 is fixedly installed on the connecting block 66, and a second guide rail 67 is installed on the clamping plate 62. The second slider 68 is slidably installed on the second guide rail 67.
[0042] Working principle:
[0043] Angle Adjustment: Before welding, ensure the circuit board is at the appropriate welding angle. Start motor 75, which acts as a power source, outputting rotational motion. The motor's rotating shaft is connected to drive shaft 72, causing drive shaft 72 to rotate as well. Each end of drive shaft 72 is connected to a synchronous belt assembly 74, which consists of a synchronous belt and synchronous pulleys, offering accurate transmission and high efficiency. When drive shaft 72 rotates, the synchronous pulleys of synchronous belt assembly 74 rotate accordingly, transmitting power to two adjusting shafts 73 via the synchronous belt, enabling them to rotate synchronously. Mounting blocks 61 are fixedly mounted on adjusting shafts 73, and these blocks are integrated with clamping plate 62. Therefore, rotation of adjusting shafts 73 causes mounting blocks 61 and clamping plate 62 to rotate together. This allows the circuit board to be welded, placed in the mounting slot 63 of clamping plate 62, to be adjusted to a suitable angle to meet the requirements of different welding processes.
[0044] Lateral Position Adjustment: After angle adjustment, the lateral position of welding mechanism 5 needs to be adjusted. Start the lateral linear module 31. The lateral linear module 31 is a device that converts the rotational motion of a motor into linear motion. It consists of a motor, lead screw, nut, and other components. When the lateral linear module 31 is working, the motor drives the lead screw to rotate, and the nut moves linearly along the lead screw. The output end of the lateral linear module 31 is connected to the mounting bracket 32, so the linear motion of the nut can drive the mounting bracket 32 to move along guide rail 33. Guide rail 33 and slider 34 form a linear motion pair, providing precise guidance and support for the movement of the mounting bracket 32, ensuring the smoothness and accuracy of its movement. The other end of the mounting bracket 32 is fixed to slider 34, and the lifting mechanism 4 is fixed to the mounting bracket 32. Therefore, the movement of the mounting bracket 32 can drive the lifting mechanism 4 and welding mechanism 5 to move together in the lateral direction, thereby achieving precise adjustment of the lateral position of welding mechanism 5.
[0045] Height Position Adjustment: After determining the lateral position of the welding mechanism 5, its height position also needs to be adjusted. Start the lifting linear module 42. The working principle of the lifting linear module 42 is similar to that of the transverse linear module 31; it also uses a motor to drive a lead screw to rotate, causing the nut to move linearly. The lifting linear module 42 is fixed on the transverse plate 41, which is fixed on the mounting bracket 32. The output end of the lifting linear module 42 is connected to the lifting block 43. When the lifting linear module 42 is working, the lifting block 43 moves up and down with the linear movement of the nut. The welding mechanism 5 is installed on the lifting block 43, so the up and down movement of the lifting block 43 can drive the welding mechanism 5 to move up and down, thereby adjusting the welding mechanism 5 to a suitable height position to meet the requirements of different circuit board thicknesses and welding positions.
[0046] Circuit board clamping: While adjusting the position of the welding mechanism 5, the circuit board to be welded needs to be clamped and fixed. The circuit board is placed in the placement groove 63 of the clamping plate 62. The shape and size of the placement groove 63 match the circuit board, providing initial positioning. Then, the clamping cylinder 65 is activated. The clamping cylinder 65 is an actuator powered by compressed air, converting the pressure energy of compressed air into mechanical energy to achieve linear reciprocating motion. The output end of the clamping cylinder 65 is connected to the clamping block 64 via a connecting block 66. A second slider 68 is fixedly mounted on the connecting block 66, and a second guide rail 67 is mounted on the clamping plate 62. The second slider 68 is slidably mounted on the second guide rail 67. When the clamping cylinder 65 operates, its output end pushes the connecting block 66, which in turn causes the second slider 68 to slide along the second guide rail 67, thereby moving the clamping block 64 towards the circuit board, clamping and fixing the circuit board to ensure that it does not shift during the welding process.
[0047] Soldering Operation: After completing the above-mentioned angle adjustment, position adjustment, and circuit board clamping preparations, the welding mechanism 5 is in a suitable position and angle, at which point the MOSFET devices on the circuit board can be soldered. The welding mechanism 5 typically consists of a welding head, a heating device, a wire feeding device, etc., and can precisely solder the MOSFET devices according to preset welding parameters, such as welding temperature, welding time, and wire feeding speed, ensuring welding quality.
[0048] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
