Under the pressing of the pressing component 6, the rotating mechanism 2 drives the first adsorption component 201 to adsorb the air-conditioning base plate 101 on the conveyor belt 1. At the same time, the air-conditioning base plate 101 adsorbed on the second adsorption component 202 cooperates with the bolt feeding mechanism 3 to transfer and feed the bolts. At the same time, the air-conditioning base plate 101 adsorbed on the third adsorption component 203 and the bolts on the air-conditioning base plate 101 cooperate with the downward moving spot welding mechanism 4 to perform corresponding spot welding. The spot-welded air-conditioning base plate 101 adsorbed by the fourth adsorption component 204 cooperates with the finished product output mechanism 5 to separate from the fourth adsorption component 204 and transfer it outward.

[0037] Here, the present invention is provided with a rotating mechanism 2 on the front side of a conveyor belt 1 for transmitting an air-conditioning base plate 101, and the rotating mechanism 2 is provided with a first adsorption component 201, a second adsorption component 202, a third adsorption component 203 and a fourth adsorption component 204 distributed in a circular array in sequence, and a matching bolt feeding mechanism 3, a spot welding mechanism 4 and a finished product output mechanism 5 are also provided in sequence on the rotation paths of the first adsorption component 201, the second adsorption component 202, the third adsorption component 203 and the fourth adsorption component 204, and the spot welding mechanism 4 is also provided with a pressing component 6 that cooperates with the rotating mechanism, and the pressing component 6 synchronously follows the spot welding mechanism 4 to move down and press the rotating mechanism 2, and the rotating mechanism 2 drives the first adsorption component 201 to adsorb the air-conditioning base plate 101 on the conveyor belt 1 under the pressure of the pressing component 6, while the air-conditioning base plate 101 adsorbed on the second adsorption component 202 cooperates with the bolt feeding mechanism 3 to It transfers and loads the bolts, and at the same time, the air-conditioning base plate 101 adsorbed on the third adsorption component 203 and the bolts on the air-conditioning base plate 101 cooperate with the downward spot welding mechanism 4 to perform corresponding spot welding, and the air-conditioning base plate 101 after spot welding adsorbed by the fourth adsorption component 204 cooperates with the finished product output mechanism 5 to separate from the fourth adsorption component 204 and transfer it outward.

The design of the equipment improves the safety during bolt welding, prevents accidental injuries during manual welding operations, and saves a lot of time and labor costs.

[0038] like Figure 2 The rotating mechanism 2 shown includes a servo motor 205 and a rotating shaft 206 driven by the servo motor 205, a limiting ring block 207 is provided at the upper end of the rotating shaft 206, a spring connecting block 208 is rotatably provided on the limiting ring block 207, a telescopic rod 209 is rotatably provided on the rotating shaft 206, a block 210 is fixedly provided on the upper end of the telescopic rod 209, and a reset spring 211 is connected between the block 210 and the spring connecting block 208.

[0039] The first adsorption component 201, the second adsorption component 202, the third adsorption component 203 and the fourth adsorption component 204 all include a rotating sleeve 212 arranged on the block 210, and an adsorption rod 213 is rotatably arranged on the rotating sleeve 212. An extension rod 214 is arranged at the end of the adsorption rod 213, and a plurality of negative pressure suction cups 215 are arranged on the extension rod 214.

[0040] Furthermore, the bolt feeding mechanism 3 includes a vibration plate 301 and a positioning box 302 arranged at the output end of the vibration plate 301, a positioning protrusion 303 is arranged on the upper end of the inner surface of the positioning box 302, and a symmetrical limiting guide block 304 is arranged on the lower side of the positioning protrusion 303. The output end of the positioning box 302 is connected to the bolt separation box 306 through a guide tube 305, and the bolt separation box 306 is provided with a through hole 307 that matches the guide tube 305. A slide groove a308 and a slide groove b309 are also opened on one side of the box 306. A cylinder 310 and a separation slide rod 311 pushed by the cylinder 310 are fixedly arranged on the outer side of the bolt separation box 306. The separation slide rod 311 is slidably set on the bolt separation box 306. A separation block a312 and a separation block b313 are set on the separation slide rod 311. The separation block a312 is slidably set on the slide groove a308, and the separation block b313 is slidably set on the slide groove b309.

[0041] It should be pointed out that the present invention is provided with a positioning box 302 below the output end of the vibration disk 301. After a single bolt output by the vibration disk 301 falls into the positioning box 302, the positioning protrusion 303 arranged on the upper part of the positioning box 302 can guide the bolt to be directionally positioned when sliding down, so that the screw rod part of the bolt enters the channel between the symmetrically arranged limiting guide blocks 304 below. The bolt then enters the bolt separation box 306 through the guide tube 305. The separation blocks a312 and b313 on the separation slide rod 311 driven by the cylinder 310 can slide left and right in the slide groove a308 and the slide groove b309. The separation blocks a312 and b313 can control a single bolt to accurately slide into the corresponding mounting hole on the air-conditioning base plate 101 and can prevent the next bolt from sliding down. The above design can effectively control the direction and quantity of the bolt output, realize the effective transfer and feeding output of the bolts of a single air-conditioning base plate 101, improve the degree of automation, and solve the disadvantages of manual installation of bolts.

[0043] It should be pointed out that the present invention provides a bolt fixing sleeve 402 on the spot welding machine 401. When the spot welding machine 401 moves downward to spot weld the bolts on the air-conditioning base plate 101, the screw rod part at the bottom of the bolt is driven to be inserted into the corresponding bolt fixing sleeve 402 for precise limiting fixation and then spot welding fixation is performed, thereby preventing the bolt from welding deformation and other unnecessary situations during the welding process, and ensuring the verticality requirement of the bolt after welding, which is conducive to the smooth installation of the subsequent compressor.

[0044] Furthermore, the finished product output mechanism 5 includes a rotating motor 501 and a pair of rotating conveyor belts 502 driven by the rotating motor 501 .

[0045] like Fig.11 and Fig.12 A top pressure sleeve 216 is rotatably provided on the block 210 shown. The telescopic rod 209, the adsorption rod 213 and the extension rod 214 are all hollow and have a negative pressure steel pipe 217 connected to the negative pressure suction cup 215 provided therein. A negative pressure machine 218 is also fixedly provided on one side of the spot welding mechanism 4. The negative pressure steel pipe 217 is connected to the negative pressure machine 218 through the top pressure sleeve 216.

[0046] Embodiment 2

[0047] like Figure 5 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that the first adsorption component 201, the second adsorption component 202, the third adsorption component 203 and the fourth adsorption component 204 are further provided with a flip component 7, and the flip component 7 includes a gear 701 fixedly provided on the adsorption rod 213, and a meshing rack a702 and a rack b703 are provided on the rotation path of the gear 701.

[0048] The working process is as follows:

[0049] The rotating mechanism 2 drives the first adsorption component 201, the second adsorption component 202, the third adsorption component 203 and the fourth adsorption component 204 to rotate reciprocatingly. When the first adsorption component 201 rotates to the conveyor belt 1, the servo motor 205 stops rotating. At this time, the air-conditioning base plate 101 that has been adsorbed by the second adsorption component 202 is at the bolt feeding mechanism 3. The specific steps of bolt transfer and feeding are as follows: the arranged output bolts on the vibration plate 301 fall into the positioning box 302, and the bolts slide through the positioning protrusions 303 in the positioning box 302. Under the action of the positioning protrusions 303, the bolts adjust their orientation, and the vertical orientation is in a state where the nut is facing up and the screw is facing down. Then, under the guidance of the limiting guide block 304 below the positioning protrusion 303, the bolts continue to slide in the channel between the pair of limiting guide blocks 304 into the guide cylinder 305, and then Then the guide cylinder 305 transfers the bolt to the through hole 307 of the bolt separation box 306, and the cylinder 310 pushes the separation slide bar 311 to the left. At this time, the separation block a312 in the slide groove a308 deviates to the left and disengages from the through hole 307. The separation block b313 in the slide groove b309 just blocks the through hole 307 so that the bolt falls on the separation block b. Then the cylinder 310 resets to the right and retracts the separation slide bar 311. At this time, the separation block a308 resets to the right to block the through hole 307 and blocks the next bolt waiting to continue sliding down. The separation block b309 resets to the right to disengage from the through hole 307, so that the bolt on the separation block b309 continues to slide to the corresponding bolt mounting hole of the air-conditioning base plate 101; at the same time, the air-conditioning base plate 101 adsorbed on the third adsorption component 203 and the bolts on the air-conditioning base plate 101 wait for the spot welding mechanism 4 to move down for welding;At the same time, the welded air-conditioning base plate 101 on the fourth adsorption component moves to the top of the finished product output mechanism 5. After the above process is completed synchronously, the spot welding mechanism 4 moves down to weld the bolts on the third adsorption component 203. At the same time, the top pressure component 6 on the spot welding structure 4 moves down synchronously to press the rotating mechanism 2. The telescopic rod 209 on the rotating mechanism 2 presses down and compresses the reset spring 211. The telescopic rod 209 presses down to drive the negative pressure suction cup 215 on the first adsorption component 201 to move down and adsorb the single air-conditioning base plate transmitted by the conveyor belt 1. The welded air-conditioning base plate 101 adsorbed on the fourth adsorption component 204 is separated from the fourth adsorption component 204 under the obstruction of the rotary conveyor belt 502 during the downward movement and is output outward along with the rotary conveyor belt 502. The four adsorption components are combined after the servo motor 205 stops. The working principle in each position under the action of the top pressure component 6 is as described above. During the rotation of the servo motor 205, a rack a702 is also provided on the path of the first adsorption component 201 turning to the second adsorption component 202. The rack a702 drives the gear 701 to rotate 180 degrees, and the gear 701 drives the adsorption rod 213 to rotate 180 degrees. The air conditioning bottom plate 101 adsorbed by the negative pressure suction cup 215 on the adsorption rod 213 also rotates 180 degrees synchronously. The air conditioning bottom plate 101 rotates 180 degrees to cooperate with the subsequent bolt loading and the outward output of the air conditioning bottom plate 101 after welding. The path of the third adsorption component 203 turning to the fourth adsorption component 204 is provided with a rack b703. The rack b703 is to continue to drive the adsorption rod 213 to rotate 180 degrees to reset it. ;
