Description

Technical Field

[0001] The present invention relates to the technical field of production of circuit boards for charging piles, and in particular to a circuit board welding device for production of charging piles. Background Art

[0002] A charging pile refers to a charging device that provides energy replenishment for electric vehicles. It is usually installed in shopping malls, public parking lots or residential communities. It can replenish the power of electric vehicles of different models. The circuit board is an indispensable circuit component in the charging pile. The circuit board is the carrier of the entire charging pile control circuit. Various electrical components are mostly soldered to the circuit board by soldering. Rosin is used as a flux during the circuit board soldering process. Rosin is a natural resin with a softening point of 72-76°C. The use of rosin can increase the smoothness of welding and form an isolation layer on the solder surface to prevent oxidation at the weld. However, due to the high temperature during the welding process, white smoke will be produced after the rosin softens. This smoke is toxic and will cause certain damage to the body and eyes. It may cause eye vascular diseases. However, the current existing welding devices only have the function of welding and cannot treat the smoke generated during the welding process.

[0003] In view of the above-mentioned drawbacks, it is necessary to design a circuit board welding device for charging pile production that can absorb smoke. Summary of the Invention

[0004] In order to overcome the shortcoming that welding equipment cannot absorb the fume generated during welding, the technical problem of the present invention is to provide a circuit board welding device for charging pile production that can absorb fume.

[0005] A circuit board welding device for charging pile production includes a workbench, a mounting frame, a welding gun, an absorption mechanism and a filtering mechanism. The workbench is placed on the ground, and the mounting frame is slidably connected to the rear side of the workbench. The mounting frame is slidably connected to a welding gun for soldering operations. The mounting frame is provided with an absorption mechanism for absorbing fume, and the absorption mechanism is internally provided with a filtering mechanism for filtering solidified rosin.

[0006] Further explanation: the absorption mechanism includes a fan, a duct, a control box and an air intake port. The bottom of the welding gun is provided with an air intake port for absorbing smoke. The upper front side of the mounting frame is connected to the fan, the left side of the fan is connected to a duct, the left side of the air intake port is connected to a duct, the left side of the front of the mounting frame is connected to the control box, and the ducts are all connected to the control box.

[0007] Further explanation: the filtering mechanism includes an outer shell, a rotating frame, a filter screen, fan blades and an air guide plate. The outer shell is connected to the right side of the control box, and the ducts are connected to the outer shell. The right side of the control box is rotatably connected to the rotating frame, which is located inside the outer shell. The outside of the rotating frame is connected to a filter screen for filtering rosin, and the inside of the rotating frame is connected to a circle of fan blades. The right side of the control box is connected to the air guide plate, which is located inside the rotating frame.

[0008] Further explanation: it also includes a sealing mechanism for preventing smoke from escaping. The sealing mechanism includes a fixed sleeve, a movable sleeve and a first spring. The fixed sleeve is connected to the lower side of the air inlet, and the movable sleeve is slidably connected to the outside of the fixed sleeve. The fixed sleeve and the movable sleeve are both made of transparent material. The first spring is mounted on both sides of the movable sleeve, and the two ends of the first spring are respectively connected to the fixed sleeve and the movable sleeve.

[0009] Further explanation, it also includes a cleaning mechanism for cleaning rosin on the filter, the cleaning mechanism includes a turntable, a belt, a brush and a receiving hopper, the turntable is connected to the left side of the turntable, the brush for cleaning rosin on the filter is rotatably connected to the right side of the control box, the turntable is connected to the left side of the brush, a belt is wrapped between the turntables, and the receiving hopper is connected to the rear side of the control box.

[0010] It is further explained that the front side of the hopper is designed to be inclined to collect the fallen rosin.

[0011] Further explanation: it also includes a cooling mechanism for quickly solidifying the rosin. The cooling mechanism includes a cold air duct and a control panel. The cold air duct is connected to the lower duct. The upper left side of the movable sleeve is connected to the control panel. Small holes are opened on the upper and lower sides of the control panel. The duct and the cold air duct are both slidably connected to the control panel.

[0012] Further explanation: it also includes an anti-clogging mechanism for preventing rosin from clogging the conduit. The anti-clogging mechanism includes a second spring and a top block. A top block for ejecting rosin is slidably connected inside the conduit. The top block is in contact with the control panel, and a second spring is connected between the air intake and the top block.

[0013] The beneficial effects of the present invention are as follows: 1.

DETAILED DESCRIPTION

[0032] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0033] Example 1

[0034] A circuit board welding device for charging pile production, such as Figure 1-Figure 2 As shown, it includes a workbench 1, a mounting frame 2, a welding gun 3, an absorption mechanism 4 and a filtering mechanism 5. The workbench 1 is placed on the ground, the mounting frame 2 is slidably connected to the rear side of the workbench 1, the mounting frame 2 is provided with an absorption mechanism 4 for absorbing smoke, the welding gun 3 is slidably connected to the front of the mounting frame 2, the welding gun 3 is used for soldering operations, and the absorption mechanism 4 is provided with a filtering mechanism 5 for filtering solidified rosin.

[0035] like Figure 3 As shown, the absorption mechanism 4 includes a fan 41, a duct 42, a control box 43 and an air intake 44. The fan 41 is connected to the upper front side of the mounting frame 2, and the duct 42 is connected to the left side of the fan 41. The bottom of the welding gun 3 is covered with an air intake 44, and the air intake 44 is used to absorb the fume generated during welding. The left side of the air intake 44 is connected to the duct 42. The control box 43 is connected to the left side of the front part of the mounting frame 2, and the ducts 42 are all connected to the control box 43.

[0036] like Figure 4-Figure 6 As shown, the filtering mechanism 5 includes a shell 51, a rotating frame 52, a filter screen 53, fan blades 54 and an air guide plate 55. Two air guide plates 55 are connected to the right side of the inside of the control box 43. The shell 51 is connected to the right side of the inside of the control box 43. The ducts 42 are all connected to the shell 51. The rotating frames 52 are rotatably connected to the right side of the inside of the control box 43. The air guide plates 55 are located inside the rotating frame 52. The rotating frame 52 is located on the inner side of the shell 51. The outside of the rotating frame 52 is connected to the filter screen 53, which is used to filter rosin in the gas. A circle of fan blades 54 is connected to the inside of the rotating frame 52.

[0037] When welding is required on the surface of the circuit board, the circuit board is fixed on the workbench 1, the switch of the welding equipment is turned on, and the mounting frame 2 moves left and right to drive the welding gun 3 to move. When the welding gun 3 moves to the position where welding is required, the switch of the fan 41 is turned on, and then the welding gun 3 moves downward to perform welding. During the welding process, smoke is generated. At this time, under the action of the fan 41, the air intake 44 absorbs the gas around the welding gun 3, and the gas enters the housing 51 through the lower conduit 42. After entering the housing 51, the gas passes through the air guide plate 55. The gas enters the fan 41 from the upper duct 42. When the gas enters the housing 51 and contacts the filter 53, the rosin in the gas solidifies and sticks to the filter 53 due to the low temperature of the filter 53, thereby completing the filtration of the rosin in the gas. After the gas passes through the air guide 55, the airflow intensity increases and the airflow impacts the fan blades 54. Under the impact of the airflow, the fan blades 54 drive the rotating frame 52 to rotate, preventing the rosin from solidifying in the same position of the filter 53 and causing the filter 53 to be blocked. When the welding work is completed, the welding equipment and the fan 41 are turned off.

[0038] Example 2

[0039] On the basis of Example 1, Figure 7 As shown, a sealing mechanism 6 for preventing smoke from escaping is also included. The sealing mechanism 6 includes a fixed sleeve 61, a movable sleeve 62 and a first spring 63. The fixed sleeve 61 is connected to the lower side of the air inlet 44. The movable sleeve 62 is slidably connected to the outside of the fixed sleeve 61. The movable sleeve 62 and the fixed sleeve 61 are both made of transparent material. The left and right sides of the movable sleeve 62 are both covered with a first spring 63. The two ends of the first spring 63 are respectively connected to the movable sleeve 62 and the fixed sleeve 61.

[0040] When the welding gun 3 moves downward, the fixed sleeve 61 and the movable sleeve 62 are driven downward by the air intake port 44. When the movable sleeve 62 contacts the circuit board, the first spring 63 is compressed and the movable sleeve 62 no longer moves downward. The welding gun 3 drives the fixed sleeve 61 to continue to move downward through the air intake port 44 to perform the welding operation. At this time, a closed space is formed around the welding gun 3. The smoke generated during the welding process is absorbed by the air intake port 44 to prevent the smoke from escaping and causing harm to the human body. After the welding is completed, the welding gun 3 moves upward. The upward movement of the welding gun 3 drives the fixed sleeve 61 and the movable sleeve 62 to move upward through the air intake port 44, and the first spring 63 is reset. Under the resetting action of the first spring 63, the movable sleeve 62 moves downward and still contacts the circuit board. At this time, the air intake port 44 can absorb the residual smoke inside the movable sleeve 62. After the first spring 63 is reset, the welding gun 3 continues to move upward, driving the fixed sleeve 61 and the movable sleeve 62 to move upward to complete the reset.

[0041] like Figure 8-Figure 9As shown, it also includes a cleaning mechanism 7 for cleaning rosin on the filter 53. The cleaning mechanism 7 includes a turntable 71, a belt 72, a brush 73 and a hopper 74. The rear side of the control box 43 is connected to the hopper 74. The front side of the hopper 74 is inclined to collect fallen rosin. The right side of the control box 43 is rotatably connected to the brush 73. The brush 73 is used to clean the rosin on the filter 53. A turntable 71 is connected to the left side of the rotating frame 52, and a turntable 71 is connected to the left side of the brush 73. A belt 72 is wound around the turntables 71.

[0042] When the rotating frame 52 rotates, the belt 72 and the turntable 71 drive the brush 73 to rotate. When the brush 73 rotates, it cleans the solidified rosin on the surface of the filter 53, causing the rosin to fall from the surface of the filter 53 and fall into the receiving hopper 74, thereby completing the collection of the solidified rosin and preventing the rosin from clogging the filter 53 and affecting the operation of the absorption mechanism 4.

[0043] like Figure 10-11 As shown, a cooling mechanism 8 for rapidly solidifying the rosin is also included. The cooling mechanism 8 includes a cold air pipe 81 and a control panel 82. The control panel 82 is connected to the upper left side of the movable sleeve 62. Small holes are provided on the upper and lower sides of the control panel 82. The lower conduit 42 is connected to the cold air pipe 81. The cold air pipe 81 and the conduit 42 are both slidably connected to the control panel 82.

[0044] When the welding gun 3 moves downward to perform welding, it drives the conduit 42, the air inlet 44, the cold air duct 81, the control board 82, the fixed sleeve 61 and the movable sleeve 62 to move downward. When the movable sleeve 62 contacts the circuit board, the movable sleeve 62 and the control board 82 stop moving downward, and the welding gun 3 continues to drive the conduit 42, the air inlet 44, the cold air duct 81 and the fixed sleeve 61 to move downward. At this time, the control board 82 blocks the cold air duct 81, and the conduit 42 is not blocked. The high-temperature smoke generated during the welding process passes through the air inlet 44 enters the conduit 42 and is absorbed. When welding is completed, the welding gun 3 moves upward, driving the conduit 42, the air intake port 44, the cold air pipe 81, the control panel 82, the fixed sleeve 61 and the movable sleeve 62 to move upward to complete the reset. After the reset is completed, the control panel 82 is no longer blocked from the cold air pipe 81, and the conduit 42 is blocked. At this time, when the absorption mechanism 4 is working, the external gas with a lower temperature is sucked into the conduit 42 through the cold air pipe 81, so that the temperature inside the conduit 42 and the shell 51 is reduced, thereby accelerating the solidification efficiency of the rosin.

[0045] like Figure 12-13As shown, it also includes an anti-clogging mechanism 9 for preventing rosin from clogging the conduit 42. The anti-clogging mechanism 9 includes a second spring 91 and a top block 92. The top block 92 is slidably connected to the inside of the conduit 42. The top block 92 slides to push the solidified rosin inside the conduit 42. The control board 82 is in contact with the top block 92. A second spring 91 is connected between the top block 92 and the air inlet 44.

[0046] When welding is not performed, the control panel 82 blocks the conduit 42. At this time, the top block 92 contacts the middle part of the control panel 82, and the second spring 91 is compressed. If welding is not performed for a long time, solidified rosin will remain inside the conduit 42. When welding is resumed, the control panel 82 no longer blocks the conduit 42, and the second spring 91 is reset. The reset action of the second spring 91 drives the top block 92 to move a short distance to the left. Since the diameter of the hole on the control panel 82 is smaller than the diameter of the top block 92, the control panel 82 blocks the top block 92. When the top block 92 moves to the left, it pushes the solidified rosin inside the conduit 42. The rosin is pushed and breaks, thereby preventing the rosin from clogging the conduit 42. At this time, the high-temperature gas around the welding gun 3 enters the conduit 42, the temperature inside the conduit 42 increases, and the rosin melts after being heated, and will not clog the conduit 42.
