The baffle 173 is connected to the cabinet 2 and is located between the first cylinder 171 and the second cylinder 172. When the first cylinder 171 and the second cylinder 172 extend, the first cylinder 171 and the second cylinder 172 push the two ends of the baffle 173 respectively, so that the first slide 153 and the second slide 154 move in opposite directions.

[0069] In one embodiment of the present application, please refer to Figure 2 , Figure 3 and Figure 8 The feeding device 3 includes a first alignment platform 3a, a second alignment platform 3c, a first reciprocating drive mechanism 3b and a second reciprocating drive mechanism 3d. The first alignment platform 3a is used to convey the tube seat 8, and the second alignment platform 3c is used to convey the tube cap. The first reciprocating drive mechanism 3b drives the first alignment platform 3a away from and close to the welding center 4, and the second reciprocating drive mechanism 3d drives the second alignment platform 3c away from and close to the welding center 4. The first alignment platform 3a is installed on the first reciprocating drive mechanism 3b, and the second alignment platform 3c is installed on the second reciprocating drive mechanism 3d. After the first alignment platform 3a absorbs the tube seat 8 from the material tray 9, the first reciprocating drive mechanism 3b drives the first alignment platform 3a to move the tube seat 8 to the welding center 4 for alignment, and then places it on the first electrode 41; after the second alignment platform 3c absorbs the tube cap from the material tray 9, the second reciprocating drive mechanism 3d drives the second alignment platform 3c to move the tube cap to the welding center 4 for alignment, and then the tube cap is adsorbed and fixed on the second electrode 42.

[0070] For further information, see Figures 8 to 10 The first alignment platform 3a includes a first suction nozzle 31, a swing assembly 32 and a first lifting assembly 33. The first suction nozzle 31 is used to suck the tube seat 8. The swing assembly 32 is used to drive the first suction nozzle 31 to move in the horizontal plane. The first lifting assembly 33 is used to drive the swing assembly 32 to rise and fall. The swing assembly 32 is installed on the first lifting assembly 33. The first lifting assembly 33 is connected to the first reciprocating drive mechanism 3b. Please refer to Figure 3 , the swing assembly 32 is used to drive the tube holder 8 adsorbed by the first suction nozzle 31 to move in the horizontal plane, and the first lifting assembly 33 drives the tube holder 8 to move up and down, so as to avoid the first suction nozzle 31 from flipping in the vertical direction, which is beneficial to reduce the displacement of the first suction nozzle 31 in the vertical direction, and is beneficial to reduce the distance between the second electrode 42 and the first electrode 41, and reduce the displacement of the second electrode 42 in the vertical direction when the welding center 4 is welded, thereby improving the welding quality and welding efficiency of the tube holder 8 and the tube cap. At the same time, since the swing assembly 32 drives the first suction nozzle 31 to move in the horizontal plane, the center of gravity of the swing assembly 32 can be avoided from changing in the vertical direction, and the load change of the swing assembly 32 can be reduced, which is beneficial to improve the accuracy of the moving position of the tube cap, reduce the response time of the swing assembly 32, and facilitate improving the alignment accuracy and efficiency of the tube holder 8 and the tube cap.

[0071] For further information, see Figures 8 to 10The second alignment platform 3c includes a second suction nozzle 34, a flip assembly 35 and a second lifting assembly 36. The second suction nozzle 34 is used to suck the pipe cap, the flip assembly 35 is used to drive the second suction nozzle 34 to flip, and the second lifting assembly 36 is used to drive the flip assembly 35 to rise and fall. The flip assembly 35 is installed on the second lifting assembly 36, and the second lifting assembly 36 is connected to the second reciprocating drive mechanism 3d. Please refer to Figure 3 When the tube cap is fed, the tube cap is placed upside down on the material tray 9, and the second suction nozzle 34 sucks up the tube cap upside down from the bottom of the tube cap. After the flip seat 352 flips, the bottom of the tube cap faces downward, and after the second electrode 42 adsorbs the tube cap, the tube cap faces the tube seat 8. After the tube cap adsorbed by the second suction nozzle 34 is flipped by the flip assembly 35, the tube cap can be adsorbed and fixed by the second electrode 42, and the tube seat 8 faces the tube cap, so that the tube cap can be covered on the tube seat 8 for welding. When the flip assembly 35 flips, the displacement of the tube cap in the vertical direction can compensate for the height from the tube cap material tray 9 to the second electrode 42, so that the lifting height of the flip seat 352 and the swing seat 322 are basically consistent.

[0072] In one embodiment of the present application, see Figure 3 , Figure 8 and Fig. 9 The swing assembly 32 includes a swing seat 322 and a swing motor 321. The swing seat 322 supports the first suction nozzle 31. The swing motor 321 drives the swing seat 322 to swing. The swing motor 321 is connected to the first lifting assembly 33, and the swing motor 321 is vertically arranged. The swing seat 322 is installed on the swing motor 321.

[0073] Optionally, see Figure 3 , Figure 8 and Fig. 9 The swing seat 322 includes a connector 3221 and at least two first arms 3222, each of which is mounted on the connector 3221, and a first suction nozzle 31 is provided at one end of each first arm 3222 away from the connector 3221. Specifically, the first suction nozzle 31 is arranged downward, and when the first suction nozzle 31 sucks the tube seat 8, the top of the tube seat 8 is sucked. By using at least two first suction nozzles 31, when the tube seat 8 is supplied, one first arm 3222 can take out the diode welded between the previous tube seat 8 and the tube cap, and then the other first arm 3222 can put the new tube seat 8 into the corresponding position, and when the first alignment platform 3a returns to suck the tube seat 8, the finished diode is put into the finished product tray 9. In this way, the time for the swing seat 322 to wait for the tube seat 8 to be welded with the tube cap is reduced.

[0074] Optionally, see Figure 3 , Figure 8 and Fig. 9There are two first arms 3222, and the two first arms 3222 are arranged perpendicular to each other. The use of two first arms 3222 can reduce the weight of the swing seat 322 and reduce the load when the swing seat 322 rotates. Optionally, each first arm 3222 is arranged along the radial direction of the rotating shaft of the swing motor 321, and the two first arms 3222 are located in the same plane.

The flip motor 351 is horizontally arranged. When the flip motor 351 rotates, the flip seat 352 can be driven to flip, so as to adjust the direction of the pipe cap on the second suction nozzle 34 and keep the pipe cap vertical.

[0076] Optionally, see Figure 3 , Figure 8 and Fig.10The flip seat 352 includes a second arm 3522 and a flip crank 3521. The flip crank 3521 supports the second arm 3522. The second suction nozzle 34 is mounted on the second arm 3522. The flip crank 3521 is mounted on the flip motor 351. The second arm 3522 is axially arranged parallel to the flip motor 351. The flip crank 3521 is used to support the second arm 3522. When the flip crank 3521 swings up and down, the height of the tube cap on the second suction nozzle 34 can be adjusted, reducing the displacement of the second lifting assembly 36 in the vertical direction. At the same time, the second arm 3522 is arranged along the axial direction of the flip motor 351, which can reduce the interference between the flip seat 352 and the second electrode 42 and the swing seat 322. Optionally, the second suction nozzle 34 is vertically fixed on the second arm 3522, and when the flip crank 3521 swings to the first position, the second arm 3522 is located at the lower side of the first arm 3222, and when the flip crank 3521 swings to the second position, the second arm 3522 is located at the upper side of the first arm 3222, wherein the first position is the position when the flip crank 3521 is vertically downward, and when the flip crank 3521 is in the first position, the second lifting assembly 36 can drive the flip assembly 35 to move downward to suck the tube cap on the material tray 9; the second position is the position when the flip crank 3521 is vertically upward, and when the flip crank 3521 is in the second position, the second lifting assembly 36 can drive the flip assembly 35 to move upward to release the adsorbed tube cap, so that the tube cap is adsorbed and fixed on the second electrode 42. In this way, the first arm 3222 and the second arm 3522 can be staggered to avoid interference between the first arm 3222 and the second arm 3522 when they move at the welding center 4.
