Description

Technical Field

[0001] This application relates to the technical field of automated welding, and in particular to a welding device for a seat controller. Background Technology

[0002] As the core electronic component of an intelligent seat system, the seat controller is responsible for key functions such as driving electric seat adjustment, heating and ventilation, and position memory. Its internal circuit board integrates high-density electronic components and complex wiring. The soldering quality directly determines the stability of signal transmission and the reliability of component connections, thus affecting the seat's electrical performance and lifespan. For example, poor soldering or uneven solder joints can lead to seat adjustment malfunctions, abnormal heating functions, and other failures. In severe cases, complete disassembly and repair may be required, impacting the user experience.

[0003] Currently, the soldering of seat controller circuit boards involves processes such as component positioning, fixing, and soldering. Operators must align the electronic component pins with the circuit board pads, fix the circuit board using clamps, and then use soldering tools to melt the solder wire, connecting the component pins to the pads. This process involves electronic components, circuit board pads, clamps, solder wire, and other parts, requiring accurate component positioning and secure soldering. Furthermore, soldering fumes are inevitably generated during the process; these fumes primarily originate from the metal vapor and flux volatiles released when the solder melts.

[0004] Regarding the aforementioned technologies, welding fumes contain lead, tin, and other metal particles, as well as volatile organic compounds. Long-term inhalation of these fumes can easily lead to respiratory irritation and heavy metal accumulation, posing health risks to operators. Furthermore, the dispersed welding fumes may adhere to the surface of circuit boards or the interior of equipment, causing secondary pollution and affecting the performance stability of other precision components. Utility Model Content

[0005] In view of the shortcomings of the existing technology, one of the objectives of this utility model is to provide a welding equipment for seat controllers.

[0006] This application provides a seat controller welding device, which adopts the following technical solution:

[0007] A welding device for a seat controller includes a frame, a welding head for welding circuit boards, a robotic arm mechanism for controlling the movement of the welding head, a clamping mechanism for holding the circuit boards, and a fume absorption mechanism for absorbing welding fumes. One end of the robotic arm mechanism is fixedly mounted on the frame, the welding head is mounted on the end of the robotic arm mechanism away from the frame, the clamping mechanism is mounted on the frame, and a mounting bracket for mounting the fume absorption mechanism is mounted on the top of the frame. The fume absorption mechanism is located above the clamping mechanism, and the end for absorbing welding fumes faces the clamping mechanism.

[0008] By adopting the above technical solutions, the robotic arm mechanism can precisely drive the welding head to any welding point on the circuit board, achieving high-precision welding of complex circuits, avoiding human operation errors, and improving welding quality; the clamping mechanism firmly clamps the circuit board, ensuring that the circuit board does not shift during the welding process; the fume absorption mechanism is installed above the clamping mechanism and faces the welding operation area, which can absorb the welding fumes in a timely manner, effectively reducing the spread of pollutants such as solder fumes in the working environment, protecting the health of operators, and preventing the accumulation of fumes from contaminating equipment parts or circuit boards.

[0009] Preferably, the robotic arm mechanism includes a base, a first movable arm, and a second movable arm. The base is rotatably mounted on the top of the frame. The first movable arm is hinged to the end of the base away from the frame. The second movable arm is hinged to the end of the first movable arm away from the base. The welding head is hinged to the end of the second movable arm away from the first movable arm.

[0010] By adopting the above technical solution, the base can rotate on the top of the frame. With the pitch and swing joints of the first and second movable arms, the welding head can achieve precise positioning in three-dimensional space at multiple angles and directions, easily reaching any welding point on the circuit board. This effectively reduces welding dead angles, reduces errors from manual operation, makes the welding quality stable and reliable, and significantly improves production efficiency.

[0011] Preferably, a first rotating shaft is provided between the base and the frame, and the base and the frame are rotatably connected through the first rotating shaft; a first pin is provided between the first movable arm and the base, the first movable arm has a first limiting groove located at the connection between the first movable arm and the base, the base is inserted into the first limiting groove, and the first pin passes horizontally through the base and the first movable arm; a second pin is provided between the second movable arm and the first movable arm, the second movable arm has a second limiting groove located at the connection between the second movable arm and the first movable arm, the first movable arm is inserted into the second limiting groove, and the second pin passes horizontally through the first movable arm and the second movable arm; a universal joint is provided between the welding head and the second movable arm, the universal joint has a horizontal axis and a vertical axis that are perpendicular to each other, the vertical axis is rotatably connected to the end of the second movable arm away from the first movable arm, and the horizontal axis is rotatably connected to the end of the welding head away from the welding point.

[0012] By adopting the above technical solution, the first rotating shaft allows the base to rotate 360 ​​degrees on the top of the frame. The base, the first movable arm, and the second movable arm are horizontally connected by the first and second pins, enabling the welding head to move in a wide range of angles in space, covering welding points at different positions and heights. This is especially suitable for all-round welding of complex circuit boards. The universal joint at the end of the welding head can independently adjust the pitch and deflection angles of the welding head through mutually perpendicular upper vertical shafts, so that it can fit the solder joint in the best posture when it reaches the target point, avoiding problems such as cold solder joints and misaligned solder joints caused by angular deviations, and significantly improving the accuracy of production.

[0013] Preferably, the clamping mechanism includes a guide rail, two sliders, two connecting rods, and two clamping blocks. Each clamping block has a clamping limiting groove, and the clamping limiting grooves of the two clamping blocks are arranged opposite to each other. The circuit board is placed in the clamping limiting grooves of the two clamping blocks. The end of each clamping block away from the clamping limiting groove is connected to the slider through the connecting rod. The guide rail is fixed to the top of the frame, and the bottom of each slider has a sliding groove. The two sliders are slidably assembled on the guide rail through the sliding groove.

[0014] By adopting the above technical solution, the relatively set clamping and limiting grooves can closely fit the edge of the circuit board, forming a stable constraint on the circuit board and effectively preventing the circuit board from shifting due to vibration or the movement of the robotic arm during the welding process; the slider can slide and adjust along the guide rail, allowing the clamping block to adapt to circuit boards of different sizes.

[0015] Preferably, the slider is provided with a second rotating shaft, one end of the connecting rod is fixed to the clamping block, and the end of the connecting rod away from the clamping block is rotatably mounted on the second rotating shaft.

[0016] By adopting the above technical solution, once one side of the circuit board is soldered, the operator does not need to disassemble the workpiece. Simply rotate the connecting rod to rotate the clamping block and the circuit board around the second axis, so that the unsoldered side faces upward. This greatly saves the time of disassembly, reassembly, and repositioning in traditional double-sided soldering, significantly improving production efficiency. During the rotation, the clamping and limiting groove of the clamping block always stably fixes the circuit board, avoiding positioning deviations caused by disassembly and reassembly, reducing manual operation steps, and lowering the risk of workpiece damage caused by frequent disassembly and reassembly.

[0017] Preferably, the dust absorption mechanism includes a dust hood, a fan, and a dust suction pipe. The dust absorption mechanism is located above the clamping mechanism. The dust hood is in the shape of an inverted funnel with its opening facing the circuit board soldering area. The end of the dust hood away from the soldering area passes through a fixing frame and is connected to the dust suction pipe. The fan is installed inside the dust suction pipe.

[0018] By adopting the above technical solution, the opening of the dust hood is directly facing the circuit board soldering area. At the first moment of the soldering fume, the funnel-shaped structure can quickly gather the welding fume through its converging effect. Combined with the strong suction generated by the fan in the dust collection pipe, the welding fume is quickly sucked in and discharged through the dust collection pipe. This effectively prevents harmful substances from spreading in the working environment, creating a clean and healthy working space for operators, reducing the harm of welding fume to the human respiratory tract and skin, and avoiding pollution or malfunctions caused by fume deposition on the surface of the circuit board or mechanical parts of the equipment.

[0019] Preferably, a filter assembly is provided inside the dust collection pipe. The filter assembly is located between the dust collection hood and the fan. It is a cylindrical body with an outer diameter that is the same as the inner diameter of the dust collection pipe. The end of the filter assembly away from the dust collection hood is detachably connected to the fan.

[0020] By adopting the above technical solutions, the filter components can effectively intercept welding fumes, ensuring that the pollutants collected by the dust collection hood are fully filtered before entering the fan, preventing untreated fumes from being directly discharged into the external environment. The detachable connection design makes it easy for operators to regularly remove the filter components for cleaning or replacement, and maintenance can be completed without complicated tools, significantly reducing the time cost and operational difficulty of equipment maintenance, and ensuring that the dust absorption mechanism maintains strong purification efficiency for a long time.

[0021] Preferably, the filter assembly includes a filter screen housing and activated carbon filled inside the filter screen housing. The filter screen housing is used to hold the activated carbon, and the activated carbon is used to adsorb welding fumes generated during welding.

[0022] By adopting the above technical solution, activated carbon, with its porous structure and adsorption capacity, can effectively capture welding fumes. Combined with the filter shell's interception of larger particulate impurities, it significantly improves the fume absorption mechanism's ability to handle complex pollutants, preventing unfiltered welding fumes from being directly emitted into the environment or damaging equipment such as fans. This provides operators with a clean working space, reduces the accumulation of pollution inside the equipment, and extends the overall system's service life.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The robotic arm mechanism can precisely drive the welding head to any welding point on the circuit board, achieving high-precision welding of complex circuits, avoiding human operation errors, and improving welding quality; the clamping mechanism firmly clamps the circuit board, ensuring that the circuit board does not shift during the welding process; the fume absorption mechanism is installed above the clamping mechanism and faces the welding operation area, which can absorb the welding fumes in a timely manner, effectively reducing the spread of pollutants such as solder fumes in the working environment, protecting the health of operators, and preventing the accumulation of fumes from contaminating equipment parts or circuit boards;

[0025] 2. The base can rotate on the top of the frame, and in conjunction with the pitch and swing joints of the first and second movable arms, the welding head can achieve precise positioning in three-dimensional space at multiple angles and directions, easily reaching any welding point on the circuit board, effectively reducing welding dead angles, reducing errors from manual operation, making the welding quality stable and reliable, and significantly improving production efficiency.

[0026] 3. The first pivot allows the base to rotate 360 ​​degrees at the top of the frame. The base, the first movable arm, and the second movable arm are horizontally connected by the first and second pins, enabling the welding head to move in a wide range of angles in space, covering welding points at different positions and heights. This is especially suitable for omnidirectional welding of complex circuit boards. The universal joint at the end of the welding head can independently adjust the pitch and deflection angles of the welding head through mutually perpendicular upper vertical shafts, so that it can fit the solder joint in the best posture when it reaches the target point, avoiding problems such as cold solder joints and misaligned solder joints caused by angular deviations, and significantly improving the accuracy of production.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0033] This application discloses a seat controller welding device.

[0034] Reference Figure 1 A seat controller welding device includes a frame 1, a welding head 2 for welding a circuit board 00, a robotic arm mechanism 3 for controlling the movement of the welding head 2, a clamping mechanism 4 for holding the circuit board 00, and a fume absorption mechanism 5 for absorbing welding fumes. One end of the robotic arm mechanism 3 is fixedly mounted on the frame 1. The welding head 2 is mounted on the end of the robotic arm mechanism 3 away from the frame 1. The clamping mechanism 4 is mounted on the frame 1 and is located within the range of motion of the robotic arm mechanism 3. A mounting bracket 6 for mounting the fume absorption mechanism 5 is mounted on the top of the frame 1. The fume absorption mechanism 5 is located above the clamping mechanism 4, and the end for absorbing welding fumes faces the clamping mechanism 4. The operator places the seat controller circuit board 00 to be welded into the clamping mechanism 4. The clamping mechanism 4 clamps and fixes the circuit board 00. Then, the robotic arm mechanism 3 moves the welding head 2 to the welding area of ​​the circuit board 00. The welding head 2 then completes the welding of all weld points sequentially according to a preset trajectory. During this process, the fume absorption mechanism 5 is activated simultaneously to absorb the welding fumes. After welding is completed, the robotic arm mechanism 3 returns to its initial position, and the clamping mechanism 4 releases the circuit board 00.

[0035] Specifically, the robotic arm mechanism 3 includes a base 31, a first movable arm 32, and a second movable arm 33. The base 31 is rotatably mounted on the top of the frame 1, forming the basic support for the robotic arm mechanism 3. The first movable arm 32 is hinged to the end of the base 31 away from the frame 1 and can swing around the hinge point in a vertical plane. The second movable arm 33 is hinged to the end of the first movable arm 32 away from the base 31, and the second movable arm 33 can further adjust its angle based on the swing of the first movable arm 32. The welding head 2 is hinged to the end of the second movable arm 33 away from the first movable arm 32 and can adjust its welding angle with the swing of the second movable arm 33. The base 31 rotates itself, driving the entire robotic arm mechanism 3 to rotate in a horizontal plane, expanding the working range of the welding head 2. The first movable arm 32 swings around its hinge point with the base 31 to adjust the height of the welding head 2. The second movable arm 33 further refines the position positioning of the welding head 2 by swinging around its hinge point with the first movable arm 32, ultimately enabling the welding head 2 to move precisely to any welding area of ​​the circuit board 00.

[0036] Furthermore, referring to Figure 2 and Figure 3A first rotating shaft 7 is provided between the base 31 and the frame 1, and the base 31 and the frame 1 are rotatably connected by the first rotating shaft 7; a first pin 8 is provided between the first movable arm 32 and the base 31, and the first movable arm 32 has a first limiting groove 9, which is located at the connection between the first movable arm 32 and the base 31. The base 31 is inserted into the first limiting groove 9, and the first pin 8 is horizontally inserted between the base 31 and the first movable arm 32, so that the first movable arm 32 can swing in the vertical plane; a second pin 10 is provided between the second movable arm 33 and the first movable arm 32, and the second movable arm 33 has a second limiting groove 11, which... The positioning groove 11 is located at the connection between the second movable arm 33 and the first movable arm 32. The first movable arm 32 is inserted into the second positioning groove 11. The second pin 10 is horizontally inserted between the first movable arm 32 and the second movable arm 33, so that the second movable arm 33 can be further adjusted in angle based on the position adjustment of the first movable arm 32. A universal joint 12 is provided between the welding head 2 and the second movable arm 33. The universal joint 12 is provided with a horizontal shaft 121 and a vertical shaft 122 that are perpendicular to each other. The vertical shaft 122 is rotatably connected to the end of the second movable arm 33 away from the first movable arm 32, and the horizontal shaft 121 is rotatably connected to the end of the welding head 2 away from the end used for welding.

[0037] Specifically, refer to Figure 2 The clamping mechanism 4 includes a guide rail 41, two sliders 42, two connecting rods 43, and two clamping blocks 44. Each clamping block 44 has a clamping limiting groove 13 with a U-shaped cross-section. The clamping limiting grooves 13 of the two clamping blocks 44 are arranged opposite to each other. The circuit board 00 to be welded is placed in the clamping limiting grooves 13 of the two clamping blocks 44 to achieve the positioning of the circuit board 00. One end of the clamping block 44 away from the clamping limiting groove 13 is connected to the slider 42 through the connecting rod 43. The guide rail 41 is fixed to the top of the frame 1. The bottom of the two sliders 42 has a sliding groove, and the two sliders 42 are slidably assembled on the guide rail 41 through the sliding groove.

[0038] Furthermore, a second rotating shaft 14 is provided on the slider 42, one end of the connecting rod 43 is fixed to the clamping block 44, and the other end of the connecting rod 43 away from the clamping block 44 is rotatably mounted on the second rotating shaft 14. When double-sided soldering of the circuit board 00 is required, the clamping block 44 clamps the circuit board 00 so that one side of the circuit board 00 faces upward, and the soldering head 2 can directly work on the solder joints. After one side is soldered, the operator can rotate the connecting rod 43 to rotate the clamping block 44 and the circuit board 00 so that the unsoldered side faces upward, and the soldering operation can be carried out directly without disassembling the circuit board 00.

[0039] Specifically, refer to Figure 1 and Figure 4The dust absorption mechanism 5 includes a dust hood 51, a fan 52, and a dust suction pipe 53. The dust absorption mechanism 5 is located above the clamping mechanism 4. The dust hood 51 is in the shape of an inverted funnel, with its opening facing the soldering area of ​​the circuit board 00. The end of the dust hood 51 away from the soldering area is inserted through the fixing frame 6 and connected to the dust suction pipe 53. The fan 52 is installed inside the dust suction pipe 53. When the circuit board 00 is being soldered, the dust absorption mechanism 5 is activated, and the fan 52 starts to run, creating a negative pressure environment inside the dust hood 51. The lead-tin fumes and flux volatiles generated by the soldering head 2 heating the solder are quickly sucked into the inverted funnel-shaped dust hood 51, pressurized by the fan 52, and transported to the outside of the equipment along the dust suction pipe 53.

[0040] Furthermore, a filter assembly 15 is installed inside the dust collection duct 53. The filter assembly 15 is located between the dust collection hood 51 and the fan 52. It is a cylindrical body with an outer diameter that is the same as the inner diameter of the dust collection duct 53. The end of the filter assembly 15 away from the dust collection hood 51 is detachably connected to the fan 52. The filter assembly 15 includes a filter screen shell 151 and activated carbon 152 filled inside the filter screen shell 151. The filter screen shell 151 is used to hold the activated carbon 152 and prevent welding slag particles from entering the fan 52 and causing damage. The activated carbon 152 is used to adsorb the welding fumes generated by welding and prevent harmful substances in the welding fumes from being discharged outdoors through the fan 52 and causing air pollution.

[0041] The implementation principle of this application embodiment is as follows:

[0042] The operator places the circuit board 00 to be soldered into the clamping and limiting groove 13 of the clamping block 44, and adjusts the spacing of the clamping blocks 44 by sliding the slider 42 on the guide rail 41 to fit the size of the circuit board 00. Then, the connecting rod 43 is rotated to fix the circuit board 00 with the side to be soldered facing upwards. The robotic arm mechanism 3 rotates horizontally through the first rotating shaft 7 at the top of the base 31 frame 1, and in conjunction with the first movable arm 32 and the second movable arm 33 swinging around the vertical planes of the first pin 8 and the second pin 10 respectively, and the welding head 2 adjusts its posture through the universal joint 12, so as to achieve precise positioning of the welding head 2 in three-dimensional space, so that it can solder the solder joints of the circuit board 00 according to the preset trajectory.

[0043] During the welding process, the fan 52 of the fume absorption mechanism 5 is activated, creating a negative pressure inside the inverted funnel-shaped dust collection hood 51. This draws the lead-tin fumes and flux volatiles generated during welding into the suction pipe 53. The filter assembly 15 inside the suction pipe 53 intercepts welding slag particles through the filter screen housing 151 and uses the activated carbon 152 filled inside to adsorb harmful gases. The purified airflow is then pressurized and discharged by the fan 52, preventing the spread of pollutants. Once the circuit board 00 is welded on one side, the operator rotates the connecting rod 43 to flip the clamping block 44, so that the unwelded side of the circuit board 00 faces upwards, allowing welding to continue without disassembly.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
