The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.
[0017] Embodiment 1, as Figure 1-5As shown, the structure of this embodiment is: a multi-axis chip welding mechanism, including a fixedly installed base 1, the upper end of the base 1 is connected to the bracket 2 through a transverse axis driving part and a longitudinal axis driving part, the transverse axis driving part includes a transverse axis guide rail 5, the transverse axis guide rail 5 is fixedly arranged, and a transverse sliding seat 6 is slidably arranged on the transverse axis guide rail 5; the longitudinal axis driving part includes a longitudinal axis guide rail 7, the longitudinal axis guide rail 7 is fixedly arranged, and a longitudinal sliding seat 8 is slidably arranged on the longitudinal axis guide rail 7, the longitudinal sliding seat 8 or the transverse sliding seat 6 is connected to the bracket 2, and a connecting part 9 is arranged between the transverse axis driving part and the longitudinal axis driving part; the transverse axis guide rail 5 and the longitudinal axis guide rail 7 intersect vertically on the vertical projection plane. In this embodiment, the connection between the longitudinal sliding seat 8 and the bracket 2 is used for explanation. For this reason, in this embodiment, the transverse axis guide rail 5 is fixedly installed on the upper end of the base 1, and a transverse axis driving mechanism 15 is provided on the base 1. The output end of the transverse axis driving mechanism 15 is connected to the connecting part 9, the transverse sliding seat 6 is fixedly connected to the lower end of the connecting part 9, the longitudinal axis guide rail 7 is fixedly installed on the upper end of the connecting part 9, and a longitudinal axis driving mechanism 16 is provided on the connecting part 9. The output end of the longitudinal axis driving mechanism 16 is connected to the bracket 2.
[0018] The bracket 2 is provided with a vertical mechanism. According to the requirements of the welding point, the number of vertical mechanisms can be multiple. In the present embodiment, two are used for illustration. The vertical mechanism includes a vertical guide rail 10 fixedly arranged on the side end of the bracket 2. A vertical seat 11 is slidably arranged on the vertical guide rail 10. The vertical seat 11 slides along the vertical guide rail 10 under the action of a vertical driving mechanism 12. The vertical seat 11 is connected to the welding seat 3 through a spring 14, and the spring 14 is vertically arranged. A pressure sensor 13 is arranged on the vertical seat 11. The sensing part of the pressure sensor 13 extends toward the welding seat 3 through the vertical seat 11. The sensing area of the pressure sensor 13 under normal conditions does not contact the upper end of the welding seat 3. The spring 14 is sleeved on the outside of the pressure sensor 13. The pressure sensor 13 and the welding seat 3 are in contact with each other. The control system is connected, and the control system includes a processing unit for analyzing the signal of the pressure sensor 13. The control system is also connected to the horizontal axis drive mechanism 15, the longitudinal axis drive mechanism 16, and the vertical drive mechanism 12 to send instructions to the above-mentioned drive mechanisms. The horizontal axis drive mechanism 15, the longitudinal axis drive mechanism 16, and the vertical drive mechanism 12 can adopt linear modules, electric push rods, etc. At the same time, proximity switches, gratings, magnetic gratings, etc. can be set on the moving path side of the horizontal sliding seat 6 and the longitudinal sliding seat 8. Detection units for detecting the moving position, the detection units are connected to the control system to send the position coordinates of the moving units such as the horizontal sliding seat 6 and the longitudinal sliding seat 8 to the control system, so as to facilitate the control system to control the movement of the bracket 2, etc., and a welding gun 4 is installed on the welding seat 3.
[0019] Specific working process: the control system drives the horizontal axis drive mechanism 15 and the vertical axis drive mechanism 16 to work so that the welding gun 4 is aligned with the welding point. When the welding gun 4 moves to the predetermined position, the vertical drive mechanism 12 starts to work to drive the two welding guns 4 to descend in sequence. After the welding gun 4 contacts the welding point, the welding gun 4 stops moving, but the vertical seat 11 continues to move downward. In this process, the sensing part of the pressure sensor 13 contacts the welding seat 3. Once the pressure sensor 13 detects a change in pressure, it immediately sends a signal to the control system. After receiving the signal from the pressure sensor 13, the control system analyzes it and controls the vertical drive mechanism 12 to stop working. At this time, the vertical seat 11 stops descending. Subsequently, the welding gun 4 starts to work and welds the solder joints on the circuit board and the chip respectively.
