[0045] The utility model is further described in detail below in conjunction with specific embodiments.

[0046] Example:

[0047] As Figure 2 shown, a comprehensive processing production line for the top cover of a battery box of the present utility model includes a first processing area 21, a buffer conveyor line 22, a second processing area 23, a continuous conveyor drying furnace 24, a drying discharge moving arm 25, a cooling conveyor line 26, and a third processing area 27 arranged in sequence.

[0048] As Figure 3 shown, the first processing area 21 includes a feeding roller group 211, a transposition coding machine 212, a first welding manipulator 213a, a second welding manipulator 213b, a first riveting moving arm 214a, a second riveting moving arm 214b, a first transfer table 215a, a second transfer table 215b, a third transfer table 215c, a first press riveting moving arm 216a, a second press riveting moving arm 216b, a first riveting machine 217a, a second riveting machine 217b, a first press riveting machine 218a, and a second press riveting machine 218b; the transposition coding machine 212 includes a rotary disk 2121, a feeding station 2122 connecting the feeding roller group 211, and a discharging station 2123 far from the feeding roller group 211. The first welding manipulator 213a and the second welding manipulator 213b are located on one side of the discharging station 2123. There are two positioning jigs (not marked) on the rotary disk 2121, and the rotary disk 2121 controls the two positioning jigs to transpose between the feeding station 2122 and the discharging station 2123. Coding mechanisms and scanning mechanisms (not marked) are provided at both the feeding station 2122 and the discharging station 2123. The first welding manipulator 213a and the second welding manipulator 213b weld the battery box top cover 1 at the discharging station 2123. The welding positions of the first welding manipulator 213a are two welding points 121 on one of its brackets 12, and the welding positions of the second welding manipulator 213b are two welding points 121 on the other bracket 12. The first riveting moving arm 214a moves the battery box top cover 1 from the discharging station 2123 to the first riveting machine 217a for riveting and then places it on the first transfer table 215a. The second riveting moving arm 214b moves the battery box top cover 1 from the first transfer table 215a to the second riveting machine 217b for riveting and places it on the second transfer table 215b. The first press riveting moving arm 216a moves the battery box top cover 1 from the second transfer table 215b to the first press riveting machine 218a for press riveting and then places it on the third transfer table 215c. The second press riveting moving arm 216b moves the battery box top cover 1 from the third transfer table 215 to the second press riveting machine 218b for press riveting and then places it at the entrance of the buffer conveyor line 22. The riveting objects are all riveting nuts 13.

[0049] The coding mechanism is used to apply traceability codes to the cover 11, facilitating product management. To balance the processing rhythm, the feeding station 2122 and the discharging station 2123 provide two fixed positions for coding and scanning. The coding and scanning on both sides are carried out synchronously, and the coding efficiency is nearly doubled compared with that of a single-station coding machine. Since there are a total of 4 welding points 121 in this embodiment, to reduce the total welding duration, the first welding manipulator 213a and the second welding manipulator 213b each weld two welding points 121, and this welding operation is completed at the discharging station 2123. Because the riveting rhythm is fast but it needs to be riveted 4 times, two sets of riveting moving arms and riveting machines are used here, and each position is riveted 3 times.

[0050] As Figure 4 shown, the second processing area 23 includes a third riveting moving arm 231a, a fourth riveting moving arm 231b, a third riveting machine 232a, a fourth riveting machine 232b, a fourth transfer table 233a, a fifth transfer table 233b, a transfer moving arm 234, two glue application transfer tables 235, two glue application moving arms 236, and two glue application machines 237. The third riveting moving arm 231a moves the battery box top cover 1 from the outlet of the buffer conveyor line 22 to the third riveting machine 232a for riveting and then places it on the fourth transfer table 233a. The fourth riveting moving arm 231b moves the battery box top cover 1 from the fourth transfer table 233a to the fourth riveting machine 232b for riveting, and then places it on the fifth transfer table 233b. The riveting object is the riveting screw 14. The transfer moving arm 234 moves the battery box top cover 1 from the fifth transfer table 233b to the idle glue application transfer table 235 and moves the battery box top cover 1 from the glue application transfer table 235 to the entrance of the continuous conveyor drying furnace 24. The glue application moving arm 236 moves the battery box top cover 1 from the glue application transfer table 235 to the glue application machine 237 for glue application and then puts it back on the glue application transfer table 235.

[0051] Both the first processing area 21 and the second processing area 23 are concentration areas for parts. In this embodiment, the number of riveting positions reaches 18. Therefore, four groups of riveting moving arms and four groups of riveting machines are used here to jointly complete the riveting at all positions, and they are distributed in the first processing area 21 and the second processing area 23. Four riveting screws 14 are riveted at each position in the first processing area 21, and five riveting screws 14 are riveted at each position in the second processing area 23. The cycle for completing the riveting in the second processing area 23 is slightly longer than that in the first processing area 21. Therefore, the battery box top cover 1 coming out of the first processing area 21 needs to wait in the buffer conveyor line 22. The buffer conveyor line 22 is arranged between the first processing area 21 and the second processing area 23. The second riveting moving arm 216b places the battery box top cover 1 at the entrance of the buffer conveyor line 22, and the third riveting moving arm 231a picks up the battery box top cover 1 from the exit of the buffer conveyor line 22. The cycle for applying glue is relatively long. Therefore, two groups of glue-applying moving arms 236 and two groups of glue-applying machines 237 are used here to synchronously apply the sealant. After scraping the glue-receiving port flat, it is sent to the continuous conveyor drying furnace 24 to dry the sealant.

[0052] In practical applications, the number of welding manipulators, the number of blind riveting moving arms, the number of riveting moving arms, and the number of glue-applying machines 237 are arranged according to the welding cycle, the blind riveting cycle, the riveting cycle, and the glue-applying cycle. The blind riveting moving arms correspond to the blind riveting machines one by one, the riveting moving arms correspond to the riveting machines one by one, and the glue-applying moving arms correspond to the glue-applying machines one by one. When welding, the position of the battery box top cover 1 is fixed, and the welding gun at the end of the welding manipulator can adjust its own angle and position to complete the welding. Each moving arm serves as both a transfer mechanism and a fixture to fix the parts, and not many moving slide rails are used, saving space. The battery box top cover 1 moves forward in a zigzag pattern between each transfer table. The welding manipulators, blind riveting machines, riveting machines, and glue-applying machines are located on both sides of the forward direction, with a compact and reasonable layout. When performing blind riveting, riveting, and glue application, the battery box top cover 1 can be visually guided and its angle and position can be adjusted, with flexible control.

[0053] As Figure 2 shown, the drying and discharging moving arm 25 moves the battery box top cover 1 processed by the continuous conveyor drying furnace 24 to the entrance of the cooling conveyor line 26.

[0054] Because the movement in the continuous conveyor drying furnace 24 is continuous, and the labeling and inspection carried out in the third processing area 27 are not continuous, a cooling conveyor line 26 needs to be set up between the two to balance the difference in rhythm. The battery box top cover 1 that has completed the drying of the sealant will naturally cool down after passing through the cooling conveyor line 26.

[0055] An unqualified product slide rail tooling 238 is arranged between the two glue-applying machines 237, and the entrance of the unqualified product slide rail tooling 238 is within the operating range of the two glue-applying moving arms 236.

[0056] When there are welding alarms, riveting alarms, press riveting alarms, or gluing alarms for the top cover 1 of the battery box, the gluing moving arm 236 will automatically place it into the non-conforming product slide rail tooling 238.

[0057] As Figure 5 shown, the third processing area 27 includes a labeling moving arm 271, two automatic labeling machines 272, a sixth transfer table 273, a slide rail manipulator 274, four airtight test benches 275, a blanking rack 276, and a rejection port 277. The labeling moving arm 271 moves the top cover 1 of the battery box from the outlet of the cooling conveyor line 26 to an idle automatic labeling machine 272 for labeling and then from the automatic labeling machine 272 to the sixth transfer table 273. The slide rail manipulator 274 moves the top cover 1 of the battery box from the sixth transfer table 273 to an idle airtight test bench 275, and then moves the top cover 1 of the battery box to the blanking rack 276 or the rejection port 277 according to the test results. The four airtight test benches 275 are arranged on one side of the slide rail manipulator 274, and the blanking rack is on the other side of the slide rail manipulator 274.

[0058] Subsequently, it will be taken by the labeling moving arm 271 to an idle automatic labeling machine 272 to stick a warning label on the surface of the top cover 1 of the battery box. After labeling is completed, the labeling moving arm 271 places it on the sixth transfer table 273. The slide rail manipulator 274 moves over to pick up the top cover 1 of the battery box from the sixth transfer table 273 and then places it on an idle airtight test bench 275 to complete the airtightness detection. When there are assembly alarms, unqualified airtight measurements, or unqualified label pasting for the top cover 1 of the battery box, the slide rail manipulator 274 sends it into the rejection port 277, otherwise the top cover 1 of the battery box is sent to the blanking rack 276. The qualified top cover 1 of the battery box can be manually inspected for appearance and packaged. The number of automatic labeling machines 272 is related to the number of airtight test benches 275 and the ratio of the labeling cycle to the airtight test cycle. The third processing area 27 is the concentration area for the third part, and the layout here can make the structure more compact.

[0059] This production line can automatically complete operations such as coding, welding, riveting, press riveting, gluing, drying, labeling, and airtightness detection, with high work efficiency.

[0060] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
