The specific operation is that the pot body to be processed is moved above the pot bottom to be pressed, and the pot body and the pot bottom are pressed by the pressing mechanism. When the finished product after the press-fitting is transferred to the pot body to be processed, it is also synchronously transferred to the finished product intermittent conveying device through one of the clamps of the double-station clamp to complete subsequent processing.

In addition, a plurality of fixing clamps 9 are provided in sequence on the finished product intermittent conveying device 1 corresponding to the height measuring device 3, the fixed plate assembly device 4, the fixed plate assembly device 5 and the latch device 6. When the finished product is transferred to the predetermined process processing position on the finished product intermittent conveying device 1, the assembled finished product is clamped by the fixing clamp 9, so that the finished product has a stable structure during the processing, reduces shaking, and has high processing quality.

[0053] In this embodiment, the finished product intermittent conveyor device 1 comprises a finished product conveyor belt 10, a plurality of limit switches 11 disposed on the finished product conveyor belt 10, and a plurality of finished product pallets 12 equidistantly disposed on the finished product conveyor belt 10. The equidistant limit switches 11 are disposed below the finished product conveyor belt 10. The limit switches 11 divide the finished product conveyor belt 10 into a plurality of corresponding workstations, each corresponding to a processing step. When the limit switches 11 are normally open, the finished product is stopped in front of the workstation. After the workstation completes, the limit switches 11 receive a signal and the finished product continues to move forward. Furthermore, a spare workstation 13 is reserved between two adjacent workstations via the limit switches 11. During use, the spare workstation 13 allows additional processing equipment to be added to the periphery of the finished product conveyor belt 10 at any time, improving processing efficiency. Furthermore, after the finished product is transferred to the finished product intermittent conveyor device 1 by the finished product assembly device 2, the finished product is sequentially received by the finished product pallets 12. The finished product pallets 12 ensure conveying stability and, under the conveying action of the finished product conveyor belt 10, the finished product pallets 12 carry the finished product to the next process.

[0054] In this embodiment, the finished product conveyor belt 10 includes an anchor bracket 100 rotatably connected to a conveyor belt 101 on the anchor bracket 100, and a drive motor 102 that drives the conveyor belt 101. The drive motor 102 is disposed below the conveyor belt 101 and transmits the driving force of the drive motor 102 to the conveyor belt 101 via a rotating shaft to realize the operation of the conveyor belt 101. In addition, the horizontal installation position of the equipment can be adjusted by providing the anchor bracket 100, so that the conveyor belt 101 has a stable structure during operation.

[0055] Furthermore, a revolving crawler belt 14 is provided below the finished product conveyor belt 10. Elevators 15 are provided at both ends of the revolving crawler belt 14. Elevators 15 include a lifting bracket 150, a lifting unit 151 mounted on the lifting bracket 150, a driving unit 152, and a lifting platform 153. The lifting unit 151 includes a back plate 1510 mounted on the lifting bracket 150, a lifting cylinder 31 connected to the back plate 1510, and a slider 632 connected to the output end of the lifting cylinder 31. The output end of the lifting cylinder 31 is vertically upward, and the slider 632 is connected to the lifting platform 153. When the lifting cylinder 31 is in use, it can push the lifting platform 153 up and down, so that the lifting platform 153 can be lifted and lowered back and forth between the conveyor belt 101 and the rotary belt 14, effectively receiving the finished product pallet 12 transmitted from the conveyor belt 101 and the rotary belt 14; in order to make the lifting platform 153 move stably, a guide rail 1513 is provided on the back plate 1510 along its height direction, and the slider 632 is slidably connected to the guide rail 1513, which effectively plays a guiding role and increases the sliding stability of the lifting platform 153.

[0056] Secondly, the driving unit 152 includes a plurality of rollers 1520 rotatably connected to the lifting platform 153 and a rolling motor 1521 that drives the plurality of rollers 1520.

When the lifting platform 153 receives the finished product pallet 12, the finished product pallet 12 is located on the plurality of rollers 1520. The rolling motor 1521 then drives the rollers 1520 to rotate, so that the finished product pallet 12 is transferred back to the conveyor belt 101 or the rotary belt 14. Thus, through the two elevators 15, the finished product pallet 12 is effectively transported back and forth between the finished product conveyor belt 10 and the rotary belt 14. It is quick to use and has high practical value. Finally, in this embodiment, a cover 1500 is provided at the top of the lifting bracket 150 above the plurality of rollers 1520.

At this time, the pot base and pot body are press-fitted and installed by the press-fit mechanism 222. Specifically, the pot body conveying mechanism 20 and the pot bottom conveying mechanism 21 are arranged in parallel, the press-fit bracket 220 is disposed at the unloading station of the pot body conveying mechanism 20 and the pot bottom conveying mechanism 21, and the press-fit mechanism 222 is disposed above the pot bottom conveying mechanism 21.

[0060] The press-fit mechanism 222 includes a support frame body 2220, a press-fit cylinder 2221 and a press-fit plate 2222 arranged on the press-fit bracket 220, wherein the support frame body 2220 is composed of a press-fit base plate 22200, four support columns 22201 arranged around the press-fit base plate 22200, and a top plate 22202 arranged on the top of the four support columns 22201. During installation, the press-fitting cylinder 2221 is fixed on the top plate 22202, and the output end of the press-fitting cylinder 2221 passes downward through the top plate 22202 and is fixedly connected to the press-fitting plate 2222. The position on the press-fitting bottom plate 22200 that is aligned with the press-fitting plate 2222 is the press-fitting station 24. The feed port of the press-fitting station 24 faces the pot bottom conveying mechanism 21, and a sensor 240 and a guide plate 241 are provided at the feed port. After the pot bottom passes through the guide plate 241 and enters the press-fitting station 24, the sensor 240 receives a signal, the conveyor belt 201 stops running, and the pot body is also moved to the pot bottom through the transfer mechanism. An electromagnetic valve 25 is provided on the top plate 22202. At this time, the electromagnetic valve 25 receives a signal to open the press-fitting cylinder 2221, driving the press-fitting plate 2222 downward to press the pot body tightly against the bottom of the pot, thereby realizing the press-fitting processing of the finished product. Finally, this processing step is repeated. When the operating mechanism 221 transfers the pot body synchronously, it will also directly transfer the press-fitted finished product to the finished product intermittent conveying device 1.

[0061] To enhance the stability of the press-fit cylinder 2221 during its extension, a guide sleeve 26 is provided around the top plate 22202. A guide post 260 is slidably connected within the guide sleeve 26. The lower end of the guide post 260 passes through the bottom plate and is fixedly connected to the press-fit plate 2222. When the press-fit cylinder 2221 is extended for use, the guide post 260 slides along the guide sleeve 26 and follows the movement of the press-fit plate 2222, thereby effectively providing guidance and stability.

[0062] In this embodiment, when the press-fitting plate 2222 is press-fitting the pot body, in order to further improve the processing stability, a splint cylinder 27 and a splint 270 connected to the splint cylinder 27 are installed on both sides of the press-fitting base plate 22200. The two splints 270 are provided with an arc-shaped groove adapted to the bottom of the pot on the opposite side. The press-fitting station 24 is also provided with a limit block 242 and a limit sensor 243 on the side away from the guide plate 241. When the bottom of the pot enters the press-fitting station 24, the bottom of the pot is close to the limit block 242, and the limit sensor 243 receives the signal to start the splint cylinder 27. The two splint cylinders 27 are synchronously displaced to clamp the bottom of the pot, waiting for the press-fitting plate 2222 to be press-fitted, and the splint 270 is released after the press-fitting, and the operating mechanism 221 directly transports the finished product away. The operation is convenient and the structure is reliable.

[0063] In this embodiment, the operating mechanism 221 includes a double-station clamp 2210 and an XY dual-axis slide 2211 that drives the displacement of the double-station clamp 2210. The XY dual-axis slide 2211 includes an X-axis servo motor 22110 and a Y-axis servo motor 22111. The X-axis servo motor 22110 drives the double-station clamp 2210 to slide left and right, while the Y-axis servo motor 22111 drives the double-station clamp 2210 to slide forward and backward. The double-station clamp 2210 includes two clamps 22100, a left-right displacement cylinder 22101, a vertical lifting cylinder 22102, and a double-head drive cylinder 22103. First, there are two left and right displacement cylinders 22101 and two up and down lifting cylinders 22102 corresponding to the two clamps 22100. The two left and right displacement cylinders 22101 are symmetrically arranged along the axis of the XY dual-axis slide 2211. The sliding directions of the two left and right displacement cylinders are opposite, and a sliding connecting plate 2212 is provided at the output end. Then the two up and down lifting cylinders 22102 are connected to the sliding connecting plate 2212, and the up and down lifting cylinders 22102 are connected to the lifting connecting plate 2213. The double-head drive cylinder 22103 is installed on the lifting connecting plate 2213. Finally, the clamp 22100 is installed on the output end of the double-head drive cylinder 22103.

[0064] During use, the XY dual-axis slide 2211 first drives the double-station clamp 2210 forward, at which point the two left and right displacement cylinders 22101 extend synchronously, causing the up-and-down lifting cylinder 22102 to extend close to the material. Then, according to the material processing requirements, one of the clamps 22100 is driven into the discharge port of the pot body conveying mechanism 20 to clamp the pot body, while the other clamp 22100 enters the press-fitting station 24 to clamp the press-fitted finished product. Finally, after the press-fitting of the finished product is completed, the cross slide then synchronously drives the two clamps 22100 to move the pot body to be press-fitted to the press-fitting station 24, and the press-fitted finished product is moved to the finished product intermittent conveying device 1. The overall operation is convenient, and the operating angle and position of the clamp 22100 can be adjusted by using the XY dual-axis slide 2211, the left and right displacement cylinders 22101, and the up-and-down lifting cylinders 22102, so that processing can be accurately carried out according to different product requirements, with high processing efficiency.

[0065] In this embodiment, when the press-fitting cylinder 2221 extends to drive the press-fitting plate 2222 to press-fit the kettle body and the kettle bottom, in order to enable the clamping jaws 22100 to maintain a downward movement trend synchronized with the kettle body, thereby reducing the shaking and deviation of the kettle body during press-fitting, a reset plate 28 is fixedly provided at the output end of the double-headed driving cylinder 22103. The top and bottom of the reset plate 28 are vertically connected to the extension plate 280. A reset guide post 281 is fixedly provided between the two extension plates 280. A spring 282 and a reset block 283 are sleeved on the reset guide post 281. The reset block 283 is located above the spring 282. Then, the clamping jaws 22100 are connected to the side of the reset block 283 facing away from the reset plate 28. This allows the jaws 22100 to grip the kettle body and, when the press-fitting cylinder 2221 extends and operates, the kettle body moves downward. The jaws 22100 automatically and synchronously move downward under the action of the spring 282, effectively ensuring the concentricity of the kettle body and a high press-fit accuracy. Once the kettle body is press-fitted, the jaws 22100 are released, and the reset block 283 automatically resets the jaws 22100 using the elastic force of the spring 282. Furthermore, to ensure the stability of the spring 282, washers 284 are provided on the reset guide post 281 at both ends of the spring 282. These washers 284 limit the spring 282 and reduce any shaking or deflection.

[0066] In this embodiment, after the pot body and the pot bottom are pressed and fitted as a finished product and are transferred to the finished product intermittent conveying device 1, further height detection is required to see whether the press-fitting meets the qualification requirements. Therefore, the height measuring device 3 provided includes a mounting frame 30, a height driving cylinder 1511, a pressing plate 32 and a digital height measuring instrument 33. A connecting plate 300 is provided on the mounting frame 30. The height driving cylinder 1511 is mounted on the connecting plate 300 by bolts, and the output end of the lifting cylinder 31 passes downward through the connecting plate 300 and is fixedly connected to the pressing plate 32. The digital height measuring instrument 33 is located above the pressing plate 32, and the digital height measuring instrument 33 is fixed on the mounting frame 30 for detecting the height.

[0067] When the finished product is transferred to the finished product intermittent conveyor 1 and located within the finished product tray 12, the lifting cylinder 31 is activated, driving the pressure plate 32 downward. After the pressure plate 32 contacts the top of the pot body, it stops for a few seconds. The digital height gauge 33 then detects the height value, effectively determining whether the press fit of the pot body is qualified. Operation is simple, and after the test, the lifting cylinder 31 resets and prepares for the next operation. To increase the stability of the lifting displacement, an auxiliary rod 3000 is provided on the connecting plate 300. The auxiliary rod 3000 passes through the connecting plate 300 and is fixedly connected to the pressure plate 332. When the pressure plate 32 moves downward, the auxiliary rod 3000 also slides synchronously, creating a reliable structure and effectively improving the extension stability of the lifting cylinder 31.

The sliding cylinder 4102 is fixedly connected to the conveying end of the lifting cylinder 4101 via the sliding connecting plate 2212. The lifting cylinder 4101 drives the sliding connecting plate 2212 to move up and down. When the multiple fixed disks on the fixed guide post 401 are transported to one end of the finished product intermittent conveying device 1, the sliding cylinder 4102 drives the lifting clamp 4100 to clamp the bottommost fixed disk on the fixed guide post 401, and then the lifting cylinder 4101 is turned on to drive the displacement upward, and the lifting height of the lifting assembly 410 is the same as the thickness of the fixed disk, so that the fixed disks are pushed out from the top of the fixed guide post 401 in sequence. At this time, the robot arm grasping assembly 411 is set on one side of the finished product conveying device, including a robot arm 4110 and a fixed disk clamp 4111 set on the robot arm 4110.

[0082] The implementation principle of an automatic assembly line for pressure kettles in an embodiment of the present application is as follows: when producing pressure kettles, the kettle body and the kettle bottom are first conveyed to a predetermined workstation by the kettle body conveying mechanism 20 and the kettle bottom conveying mechanism 21 respectively, and then the kettle body is synchronously moved to the top of the kettle bottom by the operating mechanism 221. At this time, the kettle body and the kettle bottom are press-fitted in advance by the pressing mechanism 222 above the kettle bottom. When the kettle body is transported next time, the operating mechanism 221 also synchronously transfers the pressed-fitted kettle body and kettle bottom to the finished product intermittent conveying device 1, and places them in the finished product pallet 12. After being sequentially transferred to the subsequent height measuring device 3, the fixed disk assembly device 4, the fixed plate assembly device 5 and the pin device 6 for further processing, and the pallet is clamped by the fixed clamp 9 during the processing to ensure stable processing. After the finished product pallet 12 completes one cycle of transport on the finished product intermittent conveyor 1, it is transferred by the elevators 15 at both ends, allowing it to be reused. Finally, when the pot body and pot bottom have completed all the processing steps, the finished product is grabbed by the grabbing device 80 and taken to the final process for labeling and packaging. The overall processing process is compact, the operation efficiency is high, the processing quality is high, it is very suitable for promotion and has high practical value.
