Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to a battery box coating device. Background Technology

[0002] Packet coating is a key process in battery pack production. Currently, the design dimensions of packs vary depending on the vehicle model and manufacturer, and production lines frequently need to be changed. However, traditional roller conveyors or friction roller conveyor lines have fixed installation positions and fixed line dimensions, making it necessary to change tooling or even completely incompatible when changing production models. In particular, the design of double-layer packs requires secondary coating. Traditional line solutions require additional coating equipment or transfer lines to achieve secondary coating, which increases investment costs. Moreover, the large footprint of these lines places greater demands on factory space. Utility Model Content

[0029] Example 1

[0030] like Figure 1 As shown, this embodiment provides a battery box adhesive coating device, including a frame 1, an adhesive coating mechanism 2, a conveying mechanism 3, a lifting and positioning mechanism 4, and a control system (not shown).

[0032] like Figure 1As shown, the adhesive application mechanism 2 includes a six-axis robot 21, a vision camera 22, and an adhesive application tube 23.

The vision camera 22 and the adhesive application tube 23 are fixed to the end mounting axis of the six-axis robot 21 and are symmetrically arranged about the center point of the mounting axis. They are moved by the six-axis robot 21.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the conveying mechanism 3 includes an AGV (Automated Guided Vehicle) 31, a conveyor 32, and a box-shaped tooling plate 33. The AGV 31 is existing technology. The conveyor 32 is detachably connected to the top of the AGV 31, and the box-shaped tooling plate 33 is detachably connected to the top wall of the conveyor 32. Multiple first pins 311 are fixed at intervals on the top wall of the AGV 31, and first pin holes 321 are correspondingly provided on the bottom wall of the conveyor 32 near the first pins 311.

The four legs of the conveyor 32 are each fixed with a first convex positioning plate 323 along the X-axis. The four corners of the bottom wall of the box tooling plate 33 are each fixed with a positioning leg, and the bottom of each positioning leg is fixed with a first concave positioning block 332 along the Z-axis. The positioning plate 333 is detachably connected to the box tooling plate 33. In this embodiment, the positioning plate 333 is detachably connected to the box tooling plate 33 by bolts. The positioning plate 333 can perform coarse positioning of the PACK box 5. The size of the positioning plate 333 can be replaced according to the specifications of the PACK box 5.

[0034] like Figure 2 , Figure 4 , Figure 5 , Figure 6As shown, the lifting and positioning mechanism 4 includes a first lifting and positioning component 41 and a second lifting and positioning component 42. The first lifting and positioning component 41 and the second lifting and positioning component 42 are mirror images of each other. Taking the first lifting and positioning component 41 as an example, the first lifting and positioning component 41 includes a positioning component 411 and a lifting component 412. The front and rear ends of the lifting component 412 are fixed with the positioning component 411. The positioning component 411 includes a first support frame 4111, a first cylinder 4112, and a second concave positioning block 4113. The first cylinder 4112 is fixed along the X-axis on the top wall of the first support frame 4111. The output end of the first cylinder 4112 is set towards the conveying mechanism 3 and the second concave positioning block 4113 is fixed thereon. Each second concave positioning block 4113 and each first convex positioning plate 323 are configured to cooperate with each other.

[0035] like Figure 5 , Figure 6 As shown, the lifting component 412 includes a second support frame 4121, a second cylinder 4122, a wedge block 4123, a connecting plate 4124, a wedge mating block 4125, and a second convex positioning block 4126. The second cylinder 4122 is fixed to the second support frame 4121 along the Y-axis. Multiple wedge blocks 4123 are fixed to the output end of the second cylinder 4122. A connecting plate 4124 is positioned above the second cylinder 4122 and is fixed to the second support frame 4121 via a telescopic rod 4127. Adaptable wedge blocks 4123 are fixed to the bottom wall of the connecting plate 4124 near the wedge blocks 4123. A wedge-shaped mating block 4125 is provided, which can be lifted along the wedge-shaped block 4123. A second convex positioning block 4126 adapted to the first concave positioning block 332 is fixed at each of the four corners of the top wall of the connecting plate 4124. A first upright plate is provided between the connecting plate 4124 and the second support frame 4121. The first upright plate is fixed on the second support frame 4121. Two lifting positioning sensors 4128 are fixed at intervals along the Z-axis on the top of the first upright plate. A second upright plate is fixed at both the front and rear ends of the top wall of the connecting plate 4124 near the conveying mechanism 3. An entry positioning sensor 4129 is fixed at the top of each second upright plate.

[0036] In use, the AGV31, carrying the conveyor 32, the box fixture plate 33, and the PACK box 5, enters the lifting and positioning mechanism 4. After the arrival feedback from the entry sensor 4129, the AGV31 descends and disengages from the conveyor 32. At this time, the conveyor 32 is still attached to the box fixture plate 33. Then, the first cylinder 4112 drives the second concave positioning block 4113 forward, which engages with the first convex positioning plate 323 on the side of the conveyor 32 for the first positioning. After the first cylinder 4112 magnetically opens and provides feedback on the arrival position, the piston rod of the second cylinder 4122 pushes out, passing through the wedge... The 4123 block moves to the right, causing the connecting plate 4124 to move upward. At this time, the upward-moving second convex positioning block 4126 engages with the first concave positioning block 332. Simultaneously, the second pin 322 of the conveyor 32 disengages from the second pin hole of the box tooling plate 33, which improves positioning accuracy and thus improves gluing accuracy. When the top lifting position sensor 4128 provides feedback, the positioning of the box tooling plate 33 is completed, and the positioning of the PACK box 5 is also completed. At this time, the AGV 31, the conveyor 32, and the box tooling plate 33 disengage from each other and do not affect each other.

[0037] After positioning is completed, the vision camera 22 captures the MARK points of the PACK box 5 to accurately determine the position features of the box and make corresponding coordinate compensation for the glue dispensing position. After visual positioning, the six-axis robot 21 drives the glue dispensing tube 23 to move and apply glue according to the set trajectory. The glue dispensing trajectory can be circular or wide-width. After the glue dispensing is completed, the vision camera 22 is used to detect the glue dispensing trajectory and glue type to form a closed-loop control.

[0038] After the adhesive application signal of PACK box 5 is completed, the control system completes the departure action of conveyor mechanism 3: the piston rod of the second cylinder 4122 retracts, the wedge block 4123 moves to the left to make the connecting plate 4124 move downward. At this time, the second convex positioning block 4126, which moves downward, disengages from the first concave positioning block 332. At the same time, the second pin 322 of the conveyor 32 completes the positioning connection with the second pin hole of the box tooling plate 33. After the bottom lifting position sensor 4128 gives feedback, AGV31 is positioned by the cursor at the bottom of the conveyor 32. After adjusting the position and angle of AGV31, it is lifted and connected with the conveyor 32. At this time, the connection of AGV31, conveyor 32, and box tooling plate 33 is completed. AGV31 drives the conveyor 32 and box tooling plate 33 away from the lifting and positioning mechanism 4, and the adhesive application device completes one complete action.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
