Description

Technical Field

[0001] This utility model relates to the field of relay control board processing, and in particular to a welding auxiliary tooling for the production of relay control boards. Background Technology

[0002] A relay control board is a circuit board used to control the on / off state of relays; essentially, it's a current-controlled switching device. Its main function is to control high-voltage, high-current circuits or equipment using low-voltage, low-current signals, achieving strong-weak current isolation and ensuring operational safety. For example, a 3.3V or 5V microcontroller signal can control the power supply of a 1500W oven. Relay control boards have several features: rich communication methods, supporting RS232, RS485, CAN, Ethernet, RF, etc., and often supporting the standard Modbus protocol; diverse power supply options, including wide-voltage power supply types; flexible control modes, including manual and automatic, with some supporting offline and network operation; selectable channel counts, ranging from a few to dozens, such as 8-channel, 16-channel, and 32-channel relay control boards. Its applications are wide-ranging, covering smart homes, industrial automation, robotics, and other fields. In smart homes, it can control lighting and electrical appliances; in industrial applications, it can control the start and stop of motors, valves, and other industrial equipment. Different application scenarios require the selection of appropriate relay control boards based on actual needs, such as considering parameters like the number of control channels, communication methods, and contact capacity.

[0003] When soldering relay control boards, if the board material is thin and lacks an effective fixing device, relying solely on manual pressing can easily lead to uneven force application, causing the relay pins to shift, thus reducing soldering accuracy and affecting the performance and quality of the relay control board. Furthermore, operators need to maintain a pressing posture for extended periods, which not only increases labor intensity but also increases the risk of operational errors due to fatigue, such as improper solder volume control or cold solder joints, all of which negatively impact the soldering process of relay control boards. To address this technical problem, this application proposes a soldering auxiliary fixture for the production of relay control boards. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A welding auxiliary fixture for the production of relay control boards includes an operating table.

A welding gun is inserted into the inner wall of the connecting block, and multiple limiting grooves are formed on the inner wall of the connecting block. The inner walls of the left and right limiting grooves are connected by a limiting assembly to limit the movement of the connecting block.

[0007] Furthermore, the adjustment assembly includes a first worm gear fixedly connected to the bottom of the front side of the support rod, and a first worm is rotatably connected to the inner wall of the operating table, with the outer wall of the first worm meshing with the outer wall of the first worm gear.

[0008] Furthermore, a servo motor is fixedly connected to the left side of the control panel, and the left end of the first worm gear is fixedly connected to the drive end of the servo motor.

[0009] Furthermore, two limiting rods are fixedly connected to the top of the operating table, and the outer wall of the limiting rods is slidably connected to the bottom of the clamping plate.

[0010] Furthermore, the limiting component includes a limiting block rotatably connected to the inner wall of the limiting groove, the bottom of the limiting block abutting against the top of the welding gun, a rotating rod fixedly connected to the bottom of the limiting block, and a second worm gear fixedly connected to the bottom of the rotating rod.

[0011] Furthermore, the inner wall of the connecting block is rotatably connected to two second worm gears, and the outer wall of the second worm gears meshes with the outer wall of the second worm wheel.

[0012] Furthermore, two limiting knobs are rotatably connected to the left side of the connecting block, and the left end of the second worm gear is fixedly connected to the right end of the limiting knobs.

In this utility model, when the welding gun needs to be disassembled, replaced or repaired, the limit knob is turned to make the rotating rod rotate and drive the limit block to rotate, thereby releasing the fixing of the welding gun and thus quickly disassembling the welding gun for replacement.

When starting work, the control board is placed on the operating table 1. A sliding groove is formed at the top of the operating table 1, and a clamping plate 3 is slidably connected to the top of the groove. Two support rods 7 are rotatably connected to the inner wall of the groove. The rear tops of the two support rods 7 are slidably connected to the front side of the clamping plate 3. The rotation of the two support rods 7 controls the sliding of the clamping plate 3 to clamp the control board. A first worm gear 9 is located at the bottom of the front side of the support rods 7 and is rotatably connected to the inner wall of the operating table 1. A first worm gear 10 is connected, and the outer wall of the first worm gear 10 meshes with the outer wall of the first worm wheel 9. The rotation of the first worm gear 10 meshes with the first worm wheel 9, causing the first worm wheel 9 to rotate. The rotation of the first worm wheel 9 drives the support rod 7 to rotate. A servo motor 2 is fixedly connected to the left side of the operating table 1. The left end of the first worm gear 10 is fixedly connected to the drive end of the servo motor 2. The servo motor 2 drives the first bidirectional screw 10 to rotate. Two limit rods 8 are fixedly connected to the top of the operating table 1. The outer wall of the limit rods 8 is slidably connected to the bottom of the clamping plate 3, so that the clamping plate 3 slides stably.

[0025] Reference Figure 1 , Figure 4 and Figure 5 A robotic arm 4 is fixedly connected to the top of the control panel 1. The robotic arm 4 is a programmable automation device that can move with multiple degrees of freedom via joint connections. It can carry different end effectors and is widely used in industries such as industry, aerospace, and medicine to complete various tasks. A connecting block 5 is fixedly connected to the left side of the robotic arm 4. A welding gun 6 is inserted into the inner wall of the connecting block 5. The robotic arm 4 drives the connecting block 5 and the welding gun 6 to weld the control board. Multiple limiting grooves are formed on the inner wall of the connecting block 5. Limiting blocks 11 are rotatably connected to the inner wall of the limiting grooves. The bottom of the limiting blocks 11 abuts against the top of the welding gun 6, allowing the welding gun 6 to move freely. The connecting block 11 is fixedly connected to a rotating rod 12 at its bottom, and a second worm gear 14 is fixedly connected to the bottom of the rotating rod 12. Two second worms 13 are rotatably connected to the inner wall of the connecting block 5. The outer wall of the second worm gear 14 meshes with the outer wall of the second worm 13. The second worm 13 rotates and meshes with the second worm gear 14. The meshing of the second worm gear 14 causes the rotating rod 12 to rotate, and the rotation of the rotating rod 12 drives the limiting block 11 to rotate. Two limiting knobs 15 are rotatably connected to the left side of the connecting block 5. The left end of the second worm 13 is fixedly connected to the right end of the limiting knob 15. Rotating the limiting knob 15 causes the second worm 13 to rotate.

[0026] Working principle: When starting work, place the control board on the operating table 1, start the servo motor 2 to drive the first bidirectional screw 10 to rotate, the first worm 10 rotates and meshes with the first worm wheel 9 to make the first worm wheel 9 rotate, the first worm wheel 9 rotates and drives the support rod 7 to rotate, the two support rods 7 rotate to control the clamping plate 3 to slide and clamp the control board.

[0027] When welding is required on the control board, the robotic arm 4 drives the connecting block 5 and the welding gun 6 to weld the control board. When the welding gun 6 needs to be disassembled, replaced, or repaired, the limit knob 15 is turned to rotate the second worm gear 13. The rotation of the second worm gear 13 engages with the second worm wheel 14. The engagement of the second worm wheel 14 causes the rotating rod 12 to rotate. The rotation of the rotating rod 12 drives the limit block 11 to rotate, releasing the fixation on the welding gun 6. The welding gun 6 can then be disassembled for replacement. After replacement, the welding gun 6 is inserted back into its original position, and the limit knob 15 is turned to rotate the limit block 11 to press against the top of the welding gun 6 and fix it in place.
