The vertical transmission mechanism 3 includes a cylinder fixedly connected to the frame 2, and the cylinder push rod can move linearly in the vertical direction. The cylinder push rod is arranged downward and fixedly connected to the welding head 31, and can push the welding head 31 in the vertical direction to realize the movement control of the welding head 31. Compared with motor control, cylinder transmission is simple and reliable, and energy utilization rate is high.

[0034] The horizontal transmission mechanism 14 includes a servo motor, a screw-nut pair, a guide rail 141 and a slider 142. The servo motor can control the slider 142 to move linearly in one direction on the horizontal plane. A tool box 5 is fixedly arranged on the slider 142. The tool box 5 is composed of four partitions, a cover plate and a bottom plate. The servo motor drives the screw to rotate, so that the nut in the screw-nut pair moves, and then drives the slider 142 to move along the guide rail 141, so that the tool box 5 can be controlled by the servo motor. At the same time, the servo motor can be locked to prevent the device from shaking during welding and detection work, and the control is more stable.

[0035] like Figure 5-7As shown, the fixing assembly includes a fixing seat 6 fixed above the tooling box 5, and the fixing seat 6 includes a bottom mold fixture 61 for placing the knob, and the bottom mold fixture 61 structure is adapted to the knob to be welded and detected, and a first driving member 7 that can move in the vertical direction is fixedly arranged in the tooling box 5. The first driving member 7 can be a telescopic cylinder, and its output push rod faces upward. A pressure block 8 is fixedly arranged on the output push rod of the first driving member 7. The pressure block 8 is located above the fixing seat 6 and can be driven by the first driving member 7 to move up and down, and press on the knob and the light contact piece to be welded, so as to fix the entire knob and stabilize the light contact piece.

[0036] like Figure 6 , Figure 8 As shown, the detection assembly includes a second driving member 11 fixedly arranged inside the tooling box 5, and two push rods 9 sliding relative to the fixed seat 6.

The positioning block 10 is slidably connected to each push rod 9 through a shaft sleeve, and each push rod 9 can extend above the fixed seat 6.

[0037] The bottom surface of the positioning block 10 is fixedly connected with a connecting piece 12, and the connecting piece 12 is in an "L"-shaped structure as a whole. Two secondary push rods 13 are slidably connected to the connecting piece 12. A sensor 4 is provided on the top of each secondary push rod 13. The sensor 4 can be a pressure sensor or a displacement sensor. Each secondary push rod 13 is respectively displaced directly below a push rod 9. The two secondary push rods 13 are fixedly connected to the output push rod of the second driving member 11 by setting a connecting block, and the two secondary push rods 13 can be driven to move upward in the vertical direction together, so that the sensor contacts the two push rods 9. Continue Pushing upward, the two push rods 9 move upward under the thrust and extend into the holes for installing the steel ball and the spring of the knob. When the sensor is a pressure sensor, it can be judged whether the steel ball is installed according to whether the values ​​fed back by the two sensors increase, and whether the knob is installed with a spring can be judged according to the increase in the values ​​fed back by the pressure sensor. There is a shoulder on the push rod 9 to limit the push rod 9 and prevent it from falling off due to sliding downward too long. At the same time, before the secondary push rod 13 moves upward, there is a gap between the sensor 4 at the top of the secondary push rod 13 and the push rod 9 to avoid misjudgment caused by feedback data from the sensor 4.

The main control center is arranged on the base 1, and various electric or pneumatic parts in the device are manually controlled and are all placed on the front end surface of the base 1 for easy operation. The main control center includes an emergency stop button that can stop all actions of the device.

[0042] Four anti-skid feet are provided at the bottom of the frame 2 to stabilize the entire device and prevent shaking, and to prevent ground vibrations from causing the knob placed on the bottom mold fixture 61 to shake and cause inaccurate positioning.

[0043] Specifically, the horizontal transmission mechanism 14 is driven to move the tool box 5 outwards so that the personnel can operate, the countersunk holes of the knob installation spring and the steel ball are aligned with the positions of the ejector rod 9 and placed on the bottom mold fixture 61, and then the light contact piece is placed on the corresponding reserved position on the knob, the first driving member 7 is controlled to move, and the pressing block 8 is pressed on the upper surface of the knob and the light contact piece to achieve the positioning and fixing of the knob, the horizontal transmission mechanism 14 is driven to make the part to be welded be below the welding head 31, and the camera device 15 is started to monitor the welding part;

[0044] Then, the second driving member 11 is driven to move, so that the welding head 31 contacts the welding part for welding, and the position of the tooling box is fine-tuned according to the display of the display 16 to ensure the accuracy of the welding position, and the air pump is driven to move synchronously to drive the two secondary push rods 13 to move upward, so that the two sensors 4 contact the corresponding push rods 9, drive the push rods 9 to contact the steel ball in the knob, and feed back the pressure value to the display 16, so that people can judge whether the steel ball or spring has been installed in the knob through the change of the pressure value;

[0045] After welding and testing are completed, the first driving member 7 is driven to lift and release the knob, and the second driving member 11 is driven to reset. The two push rods 9 are reset under the action of gravity. At this time, the knob can be taken out, and then the horizontal transmission mechanism 14 is controlled to move the tooling box 5 inwardly back to the frame 2 for reset to protect the internal parts and avoid bumps.

[0046] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that technical personnel in this field can implement it.
