[0002] A rectifier bridge is an electronic component, mainly composed of several rectifier diodes sealed in a housing to form a complete rectifier circuit. It is usually made up of two or four rectifier silicon wafers (diodes) connected together. It plays a key role in converting alternating current (AC) to direct current (DC) in electronic equipment and power systems. Dispensing equipment plays a vital role in the production of rectifier bridges. It is mainly used to precisely apply glue to specific parts of the rectifier bridge to achieve functions such as bonding, sealing, and protection.

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] Example: A dispensing device for the production and processing of rectifier bridges, such as... Figures 1-3 As shown, the assembly includes a support frame 1, a first motor 2, a conveying assembly 3, an infrared sensor 4, a second motor 5, a mounting bracket 6, a screw 7, a guide rod 8, an electric slide rail 9, a dispensing machine 10, screws 11, a back-suction dispensing valve 12, and a back-suction pipe 13. The support frame 1 serves as the mounting carrier for the parts. Four rectangular protective pads are provided on the lower side of the support frame 1 to protect it. The first motor 2 is bolted to the upper left side of the support frame 1. The conveying assembly 3 is mounted on the upper part of the support frame 1, consisting of pulleys and a flat belt. Pulleys are symmetrically connected to the support frame 1, with a flat belt wound between the two pulleys. The rear end of the first motor 2 is connected to the flat pulley on the left side of the support frame 1. The infrared sensor 4 is mounted on the upper part of the support frame 1, located above the conveying assembly 3. A placement bracket is connected to the support frame 1, with its upper side connected to the infrared sensor 4 to increase the connection between the sensor and the conveying assembly 3. The second motor 5 is bolted to the upper right side of the support frame 1. Mounting brackets 6 are symmetrically welded to the front and rear of the support frame 1. A screw 7 is rotatably connected to the front mounting bracket 6 of the support frame 1. A guide rod 8 is connected to the electric slide rail 9 of the rear mounting bracket 6 of the support frame 1. The electric slide rail 9 is threaded onto the screw 7. The lower rear side of the electric slide rail 9 is slidably connected to the guide rod 8. A dispensing machine 10 is mounted on the electric slider of the electric slide rail 9. The dispensing machine 10 is disassembled... The disassembly type is connected to a back-suction dispensing valve 12. A screw 11 is installed at the connection between the back-suction dispensing valve 12 and the dispensing machine 10. A back-suction pipe 13 is connected to the dispensing machine 10. The other end of the back-suction pipe 13 is connected to the back-suction dispensing valve 12. The electric slide rail and the second motor are started to adjust the dispensing machine according to the position of the rectifier bridge. The dispensing machine 10 is started to perform dispensing operation on the rectifier bridge. The back-suction dispensing valve 12 is started to drive the back-suction pipe 13 to suck the glue overflowing from the dispensing machine 10 back into the valve body.

[0021] like Figure 4 As shown, it also includes a support plate 14, a mounting frame 15, a fan 17, and a resistance wire 18. The support frame 1 has support plates 14 welded symmetrically front and back. The mounting frame 15 is connected between the upper sides of the two support plates 14. The electric slide rail 9 is located between the infrared sensor 4 and the mounting frame 15. The mounting frame 15 has evenly spaced flow grooves for heat dissipation of the fan 17. The fan 17 is symmetrically installed in the mounting frame 15. The resistance wire 18 is installed in the mounting frame 15. The fan 17 is located above the resistance wire 18. When the fan 17 is started, the resistance wire 18 is heated. The air generated by the operation of the fan 17 moves towards the rectifier bridge after being heated by the resistance wire 18, which can accelerate the curing of the adhesive.

[0022] like Figure 4As shown, it also includes a baffle 16, which is welded inside the mounting frame 15. The baffle 16 is located between the fan 17 and the resistance wire 18.

[0023] When this device is needed, the rectifier bridge is placed on the conveying assembly 3, and the first motor 2 is started. The output shaft of the first motor 2 rotates, driving the conveying assembly 3 to transport the rectifier bridge. The conveying assembly 3 moves the rectifier bridge below the infrared sensor 4, which scans it and transmits its image to the backend for reception. The conveying assembly 3 then moves the rectifier bridge below the electric slide rail 9, and the electric slide rail 9 is started. The electric slider on the electric slide rail 9 moves, driving the dispensing machine 10 to move. Once the dispensing machine 10 is above the rectifier bridge, it is started to dispense glue onto the rectifier bridge. When the rectifier bridge has moved behind the dispensing machine 10 but dispensing has not been completed, the second motor 5 is started. The output shaft of the second motor 5 rotates, driving the screw 7 to rotate. Rod 7 drives the electric slide rail 9 to move backward. When the electric slide rail 9 is above the rectifier bridge, the second motor 5 stops operating. Perform dispensing operation on the rectifier bridge as described above. After the dispensing operation is completed, start the back suction dispensing valve 12. The back suction dispensing valve 12 draws back the glue overflowing from the dispensing machine 10 through the back suction pipe 13 to prevent glue from accumulating on the needle and causing stringing. The conveying component 3 conveys the rectifier bridge to the bottom of the mounting frame 15. Start the fan 17 and control the heating of the resistance wire 18. The air generated by the fan 17 moves towards the rectifier bridge after being heated by the resistance wire 18. This can accelerate the curing of the glue on the rectifier bridge. After the heating operation is completed, turn off the equipment that needs to be started as mentioned above in sequence.
