Description

Technical Field

[0001] The utility model relates to the technical field of charging pile production equipment, in particular to a circuit board welding fixture. Background Art

[0002] Among modern charging devices, charging piles are a commonly used charging equipment. Their functions are similar to those of gas pumps in gas stations. They can be fixed on the ground or on the wall and installed in parking lots or charging stations in public buildings and residential areas. They can charge various types of electric vehicles according to different voltage levels. When manufacturers produce charging piles, they will install integrated circuit boards inside. The core component of the charging pile is the circuit board. In the process of producing the circuit board, the control components need to be fixed on the surface of the circuit board for installation and use before use. It is essential to weld the circuit board, and a clamp is needed to clamp the circuit board.

[0003] After searching, it is found that a Chinese patent announcement number CN217316971U discloses a circuit board welding fixture, which includes a welding box main body and a purification box. A support rod is fixedly connected to the lower end surface of the welding box main body, and a welding table is fixedly connected to the upper end surface of the support rod. An air pressure tank is fixedly connected to the lower end surface of the welding box main body, and the air pressure tank penetrates the welding table and is fixedly connected to the penetrating part. A connecting pipe is fixedly connected to the upper end of the air pressure tank, and an adsorption floppy disk is fixedly connected to the top of the connecting pipe. A pressure relief pipe is fixedly connected to the left surface of the air pressure tank, and a pressure relief valve is fixedly connected to the surface of the pressure relief pipe. A suction pump fixedly connected to the lower end of the welding box main body is arranged at the right end of the air pressure tank, and an air supply pipe fixedly connected to the inside of the air pressure tank is fixedly connected to the input end of the suction pump. This device can fix the circuit board very well. Compared with the traditional clamping plate fixing method, it can prevent the circuit board from being broken, which will affect its use.

[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] like Figure 1 — Figure 7 As shown, a circuit board welding fixture comprises a box body 101, a suction component 104 is installed on one side of the box body 101, a filter glass 105 is installed on the top of the box body 101, an insertion mechanism is arranged on the front side of the box body 101, a bearing mechanism is arranged inside the box body 101, the bearing mechanism comprises a welding table 301, a plurality of adsorption floppy disks 304 are fixedly installed on the top of the welding table 301, a clamping mechanism is arranged inside the box body 101, the clamping mechanism comprises a C-shaped frame 401, a cleaning mechanism for cleaning the welding table 301 and the adsorption floppy disk 304 is arranged inside the C-shaped frame 401, and the cleaning mechanism comprises a brush roller 501, and the bristles on the brush roller 501 are flexible bristles, which are conducive to cleaning the welding table 301 and the adsorption floppy disk The plate 304 is cleaned, and the brush roller 501 is rotatably connected to the rear end of the C-frame 401. Gears 502 are connected to both ends of the brush roller 501 by bolts. A rack 503 is meshed on the gear 502. The side of the gear 502 away from the brush roller 501 is rotatably connected to a mounting block 504. A groove arranged along the front-to-back direction is opened on the inner wall of the box body 101. The mounting block 504 is slidably connected in the groove of the box body 101. After the circuit board is welded, the staff pulls out the C-frame 401 to take out the circuit board. During the pulling-out process, due to the cooperation of the rack 503 and the gear 502, the brush roller 501 rotates, and the brush roller 501 sweeps out the welding slag on the welding table 301 to ensure the accuracy of the fixture positioning during multiple welding.

[0028] In this embodiment, a pad 402 is connected to the bottom of the C-shaped frame 401 by bolts, and an anti-skid layer is provided on the top of the pad 402 to prevent the circuit board from deflecting. A pull block 403 is connected to the front side of the C-shaped frame 401 by bolts. The staff pulls the pull block 403 to pull the C-shaped frame 401 out of the box body 101, so that the staff can put the circuit board inside the C-shaped frame 401. A screw rod 404 is rotatably connected to the C-shaped frame 401, and a lifting plate 405 is threadedly connected to the screw 404. The two ends of the lifting plate 405 are slidably connected to guide rods 406.

After the circuit board is placed inside the C-shaped frame 401, the positions on both sides are placed on the top of the pad 402, and the screw rod 404 is rotated to press the lifting plate 405 downward. The lifting plate 405 pushes the elastic telescopic rods 407 and the clamping plate 408 downward, so that the clamping plate 408 and the pad 402 below the clamping plate 408 clamp and position the circuit board, and the staff does not need to fix it after placing it in the box body 101, thereby ensuring the accuracy of positioning.

[0029] In this embodiment, a suction pump 302 is provided inside the welding table 301, and an air pressure tank 303 is connected to the suction end of the suction pump 302. The adsorption floppy disk 304 is connected to the air pressure tank 303 through a pipeline. A pressure relief valve 306 is provided on the side of the air pressure tank 303. The suction pump 302 and the pressure relief valve 306 can be used to control whether the adsorption floppy disk 304 adsorbs the circuit board.

[0030] In this embodiment, the rack 503 is arranged above the gear 502, so as to enable the brush roller 501 to sweep the welding slag from the back to the front.

[0031] In this embodiment, a wedge block 505 is provided below the rack 503 . The wedge block 505 is connected to both sides of the welding platform 301 by bolts. The wedge block 505 is used to guide the welding slag falling on both sides of the welding platform 301 to the front position.

[0032] In this embodiment, a dustproof filter block 305 is bonded to the adsorption disk 304 , and the dustproof filter block 305 is used to prevent welding slag from falling into the air intake port of the adsorption disk 304 .

[0033] In this embodiment, a closed door 102 is hinged on the front side of the box 101, and a collection box 103 is connected to the front side of the box 101 by bolts. The welding slag dropped on the welding table 301 is swept out by the brush roller 501, and the welding slag remaining on the circuit board can be used.

[0034] In this embodiment, the insertion mechanism includes two insertion ports 201, which are arranged at the upper front side of the box body 101. A sealing sleeve 202 is arranged in the insertion port 201, and an elastic ring 203 is connected to the sealing sleeve 202 by bolts. The staff holds a welding gun and inserts it into the box body 101 through the insertion port 201 to perform welding work on the circuit board, which effectively prevents the inhalation of welding gas.

[0035] Working principle: When the device is in use, in the initial state, the C-frame 401 is located inside the box 101, and the closed door 102 is in a closed state. The staff takes the charging pile circuit board to be welded to the box 101, opens the closed door 102, pulls the pull block 403 to extract the C-frame 401, and places the circuit board inside the C-frame 401. The positions on both sides of the circuit board are placed on the top of the pad 402, and the screw 404 is turned to press the lifting plate 405 downward. The lifting plate 405 pushes the elastic telescopic rod 407 and the clamping plate 408 downward, so that the clamping plate 408 and the pad 402 under the clamping plate 408 clamp and position the circuit board, and then pushes the pull block 403 to push the C-frame 401 into the box 101, closes the closed door 102, and uses the suction pump 302 to pump the air pressure tank 303 into negative pressure, and the adsorption floppy disk 304 adsorbs and fixes the circuit board, further ensuring The clamp positioning effect, then the staff holds the welding gun and extends it into the box 101 from the insertion port 201 to weld the circuit board. The setting of the filter glass 105 prevents the welding light from being too strong and hurting the staff's eyes. During the welding process, the suction component 104 extracts the welding gas to prevent the gas from being discharged into the air. After the welding is completed, the closed door 102 is opened and the pull block 403 is pulled out. The pull block 403 drives the C-shaped frame 401 to move outward. During the pulling process, due to the cooperation of the rack 503 and the gear 502, the brush roller 501 rotates, and the brush roller 501 sweeps out the welding slag on the welding table 301. When the C-shaped frame 401 is pulled to the front end of the box 101, it is shaken up and down to shake off the residual welding slag on the circuit board, and the welding slag swept off the welding table 301 falls into the collection box 103. Then the screw 404 is rotated in the opposite direction to release the fixation of the circuit board to complete the welding work.
