Description

Technical Field

[0001] This utility model relates to the field of motor and fan manufacturing technology, specifically to an automatic wave soldering and cutting device for coil motor pins and a complete PCBA board. Background Technology

[0002] During the manufacturing process of motors and fans, the pins of the internal coil motor need to be welded and fixed to the PCBA using welding and cutting equipment.

[0003] However, existing welding and cutting equipment still has the following technical problems in use:

[0004] Existing soldering methods mainly use single-pin soldering, where the soldering station simultaneously melts solid solder wire onto the PCBA pads to complete the soldering. The solder melting process may lead to defects such as missing solder joints, cold solder joints, and poor solder joints. During assembly, assembly is done manually, with each PCS being soldered individually, which is inefficient. Placing the soldered components on trays is time-consuming. The gap between the PCBA and the stator wires (coils) is unstable during manual assembly and handling, which can easily cause potential product quality issues.

[0005] To address these issues, an automatic wave soldering and cutting device for coil motor pins and the entire PCBA board is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an automatic wave soldering and cutting device for coil motor pins and the entire PCBA board, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic wave soldering and cutting device for coil motor pins and a complete PCBA board, comprising a first frame, a complete board assembly carrier fixed on the upper side of the first frame, a finished product transfer and transverse module fixed on the upper side of the first frame at the upper end of the complete board assembly carrier, a second frame fixed on the rear side of the first frame, a wave soldering device fixed on the upper side of the second frame, a transport robotic arm fixed on the upper side of the second frame at the upper end of the wave soldering device, a stamping-type cutting cylinder fixed on the right end of the upper side of the first frame, an automatic loading and unloading device fixed on the right side of the first frame, and a rotating gripper and XY axis motion module fixed on the upper end of the automatic loading and unloading device.

[0008] Preferably, the lower sides of both the first frame and the second frame are fixed with casters with foot brakes and adjustable support bases.

[0009] Preferably, both the first frame and the second frame are provided with processing tool storage cabinets on their side walls.

[0010] Preferably, a symmetrical welding parameter adjustment display screen is fixed to the side wall of the second frame, and the welding parameter adjustment display screen is electrically connected to the wave soldering equipment.

[0011] Preferably, the rotation angle of the handling robotic arm is 360 degrees.

[0012] Preferably, the rotating gripper picking and XY axis motion module is configured as four sets.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This application improves upon the traditional method of simultaneous soldering with solid solder wire and soldering iron by using liquid solder furnace wave spraying to ensure that products do not suffer from defects such as missing solder, cold solder, or poor soldering. A dedicated carrier design combines the entire PCBA board with stator wire entry positioning, further secured by spring clips, ensuring a firm fit and eliminating quality risks caused by loose component connections. A 360-degree rotating robotic arm picks up the entire carrier, transports it to the wave soldering position for precise positioning, and simultaneously sprays flux. Combined with XY-axis positioning motion, wave soldering is performed, with 15 pieces soldered at a time. The robotic arm then retrieves the entire carrier and places it on the assembly line for further processing. A servo-driven carrier positions the product at a stamping-type cutting station, with cylinder limiters moving synchronously to prevent PCBA components and coil copper wires from being damaged by structural pressure. 15 pieces are cut at a time. The entire carrier is then transported to the finished product unloading position, where four sets of rotating grippers pick up and load the product onto a tray. Attached Figure Description

[0025] Example:

[0026] Please see Figure 1-7 This utility model provides a technical solution:

[0027] The automatic wave soldering and cutting device for coil motor pins and the entire PCBA includes a first frame 1. A PCBA assembly carrier 2 is fixed to the upper side of the first frame 1. The PCBA and stator input wires are positioned and assembled using the PCBA assembly carrier 2, and spring clips apply force for positioning, ensuring a secure assembly and preventing quality risks caused by loose component connections. A finished product transfer and transverse movement module 3 is fixed to the upper side of the first frame 1, located at the upper end of the PCBA assembly carrier 2. A second frame 4 is fixed to the rear side of the first frame 1. A wave soldering device 5 is fixed on the upper side of the frame 4. The wave soldering device effectively replaces the previous soldering method and uses liquid tin furnace wave spraying soldering to ensure that the product has defects such as missing solder, cold solder, and false solder. A handling robot arm 6 is fixed on the upper side of the second frame 4 above the wave soldering device 5. A stamping cutting cylinder 7 is fixed on the right side of the upper side of the first frame 1. An automatic loading and unloading device 8 is fixed on the right side of the first frame 1. A rotating gripper and XY axis motion module 9 is fixed on the upper end of the automatic loading and unloading device 8.

[0028] The lower sides of both the first frame 1 and the second frame 4 are fixed with casters 10 with foot brakes and adjustable support bases 11. When movement is required, the adjustable support base 11 can be moved upward to contact the limit of the casters 10 with foot brakes, which facilitates the movement of the first frame 1 and the second frame 4. When in use, it is necessary to ensure that the lower side of the adjustable support base 11 is in contact with the ground to increase stability.

[0029] Both the first frame 1 and the second frame 4 are equipped with processing tool storage cabinets 12 on their side walls for storing the tools needed during the processing.

[0030] The side wall of the second frame 4 is fixed with a symmetrical welding parameter adjustment display screen 13, which is electrically connected to the wave soldering equipment 5.

[0031] The robotic arm 6 has a rotation angle of 360 degrees. The rotating gripper and XY axis motion module 9 are set to four groups. This application realizes automatic PCBA cutting, saving manpower. The whole board and stator are assembled and positioned at one time and welded simultaneously in 15 pieces, which improves efficiency, ensures consistent welding appearance, and the size of the solder joints is controllable, flat and smooth.

[0032] Working principle:

[0033] During processing, the coil and the entire PCBA board are loaded into the board assembly carrier 2 and positioned. The transport robot arm 6 moves the carrier from the streamline limit point to the welding table for flux spraying and then performs wave soldering through the wave soldering equipment 5. After welding, the transport robot arm 6 moves the entire board to the welded finished product transfer transverse module 3 and conveys it to the next work station. The welded finished product and the carrier are conveyed to the cutting position and cut synchronously by the cylinder positioning of the stamping cutting cylinder 7. After cutting, the material is picked up by the rotating gripper and the XY axis motion module 9 and loaded onto the tray. The trayed finished products are replaced by the automatic loading and unloading device 8.
