Description

Technical Field

[0001] This utility model relates to the field of power motherboard manufacturing technology, specifically a welding device for welding intelligent power motherboards. Background Technology

[0002] Power motherboards are computer motherboards used in the power industry. They are typically designed to operate stably in harsh environments and withstand conditions such as high temperature, high humidity, and dust. During the production process, power motherboards require soldering equipment to solder their surfaces.

[0003] A search revealed that patent number CN211804271U, entitled "Utility Model of a Motherboard Welding Device," includes a welding mechanism, a lifting mechanism, a lateral movement mechanism, and a support mechanism. Research and analysis revealed that while the welding mechanism can be moved up and down by a lifting cylinder during use, enabling free and mechanized movement with more precise positioning and reduced manual operation efficiency; it also allows for welding with a welding pen and the use of a suction pump to recover excess solder, preventing short circuits on the motherboard due to excess solder and avoiding solder waste. However, it also has certain drawbacks.

[0004] For example, if the device lacks a smoke extraction function, it cannot centrally discharge the fumes generated during the soldering of the motherboard surface, causing the fumes to easily drift around the workshop and thus endanger the health of the workers. In order to solve the above technical problems, we have designed an intelligent welding device for soldering power motherboards. Utility Model Content

[0005] The purpose of this utility model is to provide a welding device for intelligent power motherboard welding, which has the advantages of smoke exhaust and quality inspection functions, and solves the problem that existing motherboard welding devices cannot centrally exhaust and treat the fumes generated during welding, and do not have quality inspection functions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding device for welding intelligent power motherboards, comprising a base plate, wherein a first linear motor is embedded and installed on the front and rear sides of the top of the base plate, a second linear motor is bolted to the moving end of the first linear motor, a positioning plate is bolted to the moving end of the second linear motor, a vertical plate is riveted to the front and rear sides of the top of the base plate, a horizontal plate is riveted to the top of the opposite side of the vertical plate, a housing is riveted to the opposite side of the horizontal plate, a slide rail is riveted to the front and rear sides of the inner cavity of the housing, an activated carbon filter is movably connected to the inner cavity of the slide rail, a fan is bolted to the top of the housing, a support rod is welded to the front and rear sides of the left side of the housing, a detection mechanism is riveted to the left end of the support rod, a controller is bolted to the bottom of the front side of the vertical plate, an electric push rod is bolted to the bottom of the housing, and a soldering gun is bolted to the output end of the electric push rod.

[0007] Preferably, the detection mechanism includes a fixed plate, the right side of which is welded to a support rod, a lead screw threaded through the front side of the top of the fixed plate, a movable plate movably connected to the bottom end of the lead screw via a bearing, a vision sensor connected to the bottom of the movable plate via bolts, a controller electrically connected bidirectionally to the vision sensor, a buzzer connected to the top of the fixed plate via bolts, a handwheel riveted to the top of the lead screw, and a unidirectional electrical connection between the output end of the controller and the buzzer.

[0008] Preferably, a guide rod is riveted to the rear side of the top of the movable plate, and the top end of the guide rod extends through to the top of the fixed plate.

[0009] Preferably, a sealing plate is bolted to the right side of the housing, and a handle is riveted to the right side of the sealing plate.

[0010] Preferably, the air inlet pipe of the fan is connected to the housing, and the air outlet pipe of the fan is connected to a smoke exhaust pipe.

[0011] Preferably, the bottom of the housing has an air inlet, and the output of the controller is unidirectionally connected to the first linear motor, the second linear motor, the fan, and the electric push rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model has the advantage of smoke exhaust function through the cooperation of box body, slide rail, activated carbon filter and fan. During the welding process, the other end of the smoke exhaust pipe is placed outdoors, the controller controls the operation of the fan, the fan draws the smoke through the air inlet, the smoke enters the inner cavity of the box body, the activated carbon filter adsorbs and filters the particulate impurities contained in the smoke, and the filtered smoke is discharged to the outside through the smoke exhaust pipe, thereby preventing the smoke from spreading around the workshop.

[0014] 2. This utility model has the advantage of quality inspection function through the cooperation of fixed plate, lead screw, movable plate, vision sensor and buzzer. Rotating the handwheel drives the lead screw to rotate, and the lead screw drives the movable plate and vision sensor to move downward. After the main board is soldered, it is transported to the left. At this time, the vision sensor detects the solder joint. When the solder joint is detected to be unqualified, the controller controls the buzzer to sound an alarm. Attached Figure Description

[0024] Please see Figure 1 The air inlet pipe of the fan 10 is connected to the housing 7, and the air outlet pipe of the fan 10 is connected to the smoke exhaust pipe 24. Through the smoke exhaust pipe 24, the smoke can be discharged to the outside, preventing the smoke from spreading indoors.

The flue gas enters the inner cavity of the box 7. The activated carbon filter 9 adsorbs and filters the particulate impurities contained in the flue gas. The filtered flue gas is discharged outdoors through the exhaust pipe 24, thereby preventing the flue gas from spreading around the workshop. After the soldering is completed, the first linear motor 2 operates, driving the power main board to move to the left. At this time, the vision sensor 19 detects the solder joint.
