Description

Technical Field

[0001] The utility model relates to the technical field of electric box loading technology, and particularly relates to an electric box rack transfer line. Background Art

[0002] The electric box (or battery pack) loading process refers to loading the electric box into a container, which involves the feeding process of the electric box. In the feeding process of the electric box, the electric box is usually loaded on a rack, and the locking mechanism on the rack locks and limits the electric box. The locking mechanism mainly includes a hollow lock box 1, a lock post 2, a stop block 3, a hook block 4, a dial block 5 and a return spring (as Figure 1 shown). When unlocking, the left end of the hook block 4 is pushed to make the hook block 4 rotate clockwise around its middle part. The right end of the hook block 4 is separated from the stop block 3, and the return spring in the lock box 1 pushes the stop block 3 to move rightward, thereby synchronously driving the lock post 2 to move rightward, so that the left end of the lock post 2 retracts into the lock box 1 and no longer locks and limits the electric box.

[0003] At present, the unlocking of the rack in the existing electric box loading process is mainly manually operated, and the recycling of the rack after the electric box is loaded into the rack is also manually transported, with low efficiency, high labor cost and low automation degree.

[0037] Embodiment 1

[0038] As Figure 2 and Figure 3 shown, an electric box rack transfer line includes a box rack loading mechanism 100, a rack unloading mechanism 200, a rack handling mechanism 300, and an unlocking mechanism 400. The box rack loading mechanism 100 and the rack unloading mechanism 200 are arranged side by side. The rack handling mechanism 300 is longitudinally arranged on the right side of the box rack loading mechanism 100 and the rack unloading mechanism 200. The unlocking mechanism 400 is installed in the middle of the box rack loading mechanism 100. The box rack loading mechanism 100 realizes the automatic loading and transfer of the rack with the electric box. The unlocking mechanism 400 unlocks the transferred rack. Then, an electric box gripper (not shown in the figure) removes the electric box on the rack for subsequent box loading process. Finally, the rack handling mechanism 300 transports the empty rack to the rack unloading mechanism 200 for automatic transfer and recycling offline. The whole process is automated, with high efficiency and reduced manual participation. Specifically, the electric box gripper is a prior art, and its specific structure will not be described in detail here.

[0039] As Figure 2 and Figure 7As shown in the figure, the on-line mechanism 100 of the box rack includes an on-line bottom frame 110, an on-line adjusting frame 120, a first lead screw nut assembly 130, a lifting assembly 140, and a first slide table 150. The on-line bottom frame 110 is horizontally arranged. There are two on-line adjusting frames 120, which are respectively horizontally arranged at the front and rear ends of the on-line bottom frame 110. The on-line adjusting frames 120 are slidably installed on the on-line bottom frame 110. The first lead screw nut assembly 130 is arranged between the on-line bottom frame 110 and the on-line adjusting frames 120 to drive the two on-line adjusting frames 120 to approach or move away from each other. There are several groups of lifting assemblies 140, which are installed on the on-line adjusting frames 120 at intervals along the horizontal direction, and the lifting assemblies 140 on the two on-line adjusting frames 120 are arranged opposite to each other. There are several first slide tables 150, which are movably installed on the on-line adjusting frames 120 and are arranged inside the lifting assemblies 140. Specifically, the first lead screw nut assembly 130 includes a bidirectional lead screw, a nut block, and a servo motor. The bidirectional lead screw is longitudinally arranged on the on-line bottom frame 110. The nut block is threadedly sleeved on the bidirectional lead screw and is connected to the on-line adjusting frame 120. This is the prior art. There are three groups of lifting assemblies 140 on each on-line adjusting frame 120, which are sequentially marked as No. I, No. II, and No. III from left to right. There are two first slide tables 150 on each on-line adjusting frame 120, which are sequentially marked as No. 1 and No. 2 from left to right. During on-line transfer, a rack gripper (not shown in the figure) transports the rack loaded with the electrical box to the No. I lifting assembly 140. Then, the No. I lifting assembly 140 lifts the rack to a certain height. The No. 1 first slide table 150 moves to directly below the rack. The No. I lifting assembly 140 drives the rack to descend until the rack lands on the No. 1 first slide table 150. The No. 1 first slide table 150 transfers the rack to the No. II lifting assembly 140. The No. II lifting assembly 140 lifts the rack. The No. 1 first slide table 150 moves left to transport the next rack. The No. II lifting assembly 140 drives the rack to descend and reset. The unlocking mechanism 400 unlocks the rack. After unlocking, the No. II lifting assembly 140 lifts the rack again. The No. 2 first slide table 150 moves to directly below the rack. The No. II lifting assembly 140 drives the rack to descend until the rack lands on the No. 2 first slide table 150. The No. 2 first slide table 150 transfers the rack to the No. III lifting assembly 140. The No. III lifting assembly 140 lifts the rack. The No. 2 first slide table 150 moves left to transport the next rack. The No. III lifting assembly 140 drives the rack to descend and reset. After resetting, the electrical box gripper removes the electrical box on the rack. The rack handling mechanism 300 transports the empty rack to the off-line mechanism 200 of the rack.

There are two material receiving plates 142, which are installed at the top of the material receiving rack 141 at intervals in the transverse direction. The first positioning angle 143 is installed in the middle of the top of the material receiving plate 142. The lifting plate 144 is slidably installed in the material receiving rack 141 and is arranged between the two material receiving plates 142. The lifting electric cylinder 145 is vertically arranged in the material receiving rack 141, and its driving end is connected to the lifting plate 144. When the material rack lands on the lifting assembly 140, the pin at the bottom of the material rack is inserted into the first positioning angle 143 to realize the positioning of the material rack. When lifting, the lifting electric cylinder 145 drives the lifting plate 144 to rise, and then contacts the material rack to push the material rack up until it rises to a predetermined position. At this time, the pin at the bottom of the material rack disengages from the first positioning angle 143.

[0041] As Figure 7 and Figure 9 shown in the figure, the first sliding table 150 includes an upper line vehicle frame 151, a limiting block 152, and a first gear-rack assembly 153. The upper line vehicle frame 151 is slidably installed on the upper line adjusting rack 120. There are several limiting blocks 152, which are arrayed at the top of the upper line vehicle frame 151. The first gear-rack assembly 153 drives the upper line vehicle frame 151 to move horizontally. Specifically, the first gear-rack assembly 153 includes a rack, a gear, and a servo motor. The rack is horizontally arranged on the upper line adjusting rack 120. The servo motor is installed in the upper line vehicle frame 151, and its output end is meshed with the rack through the gear.

[0042] As Figure 2 and Figure 10As shown in the figure, the off-line mechanism 200 of the rack includes an off-line chassis 210, an off-line adjusting frame 220, a second lead screw nut assembly 230, a support assembly 240, and a second slide table 250. The off-line chassis 210 is horizontally arranged. There are two off-line adjusting frames 220, which are respectively horizontally arranged at the front and rear ends of the off-line chassis 210. The off-line adjusting frames 220 are slidably installed on the off-line chassis 210. The second lead screw nut assembly 230 is arranged between the off-line chassis 210 and the off-line adjusting frames 220 to drive the two off-line adjusting frames 220 to approach or move away from each other. There are several groups of support assemblies 240, which are installed on the off-line adjusting frames 220 at intervals in the horizontal direction, and the support assemblies 240 on the two off-line adjusting frames 220 are arranged opposite to each other. There are several second slide tables 250, which are movably installed on the off-line adjusting frames 220 and are arranged inside the support assemblies 240. Specifically, the structure of the second lead screw nut assembly 230 is the same as that of the first lead screw nut assembly 130; there are three groups of support assemblies 240 on each off-line adjusting frame 220, which are sequentially marked as No. IV, No. V, and No. VI from right to left; there are two second slide tables 250 on each off-line adjusting frame 220, which are sequentially marked as No. 3 and No. 4 from right to left. During off-line transfer, the rack handling mechanism 300 transports the empty rack to the No. IV support assembly 240. The No. 3 second slide table 250 moves to directly below the rack. The No. 3 second slide table 250 jacks up the rack, then transfers the rack above the No. V support assembly 240. The No. 3 second slide table 250 drives the rack to descend and reset, so that the rack falls on the No. V support assembly 240. The No. 3 second slide table 250 moves to the right to transport the next rack. The No. 4 second slide table 250 moves to directly below the rack. The No. 4 second slide table 250 jacks up the rack, then transfers the rack above the No. VI support assembly 240. The No. 4 second slide table 250 drives the rack to descend and reset, so that the rack falls on the No. VI support assembly 240. The No. 4 second slide table 250 moves to the right to transport the next rack. The forklift forks away the rack on the No. VI support assembly 240.

[0043] As Figure 7 and Figure 10 shown, by driving the two on-line adjusting frames 120 to approach or move away from each other through the first lead screw nut assembly 130 and driving the two off-line adjusting frames 220 to approach or move away from each other through the second lead screw nut assembly 230, the compatibility of racks of different sizes is achieved, thus improving the compatibility and practicability of the entire device.

[0051] Embodiment 2

[0052] On the basis of Embodiment 1, this embodiment adds a stacking mechanism 500 to stack the empty racks flowing on the rack offline mechanism 200, realizing the one-time recovery of multi-layer racks, reducing the handling times during the recovery process, and further improving the work efficiency.

[0053] As Figure 2 and Figure 15 shown in the figure, the stacking mechanism 500 includes two vertical frames 510, a lifting plate 520, a second lifting electric cylinder 530, a lifting plate 540 and a driving cylinder 550. The two vertical frames 510 are oppositely arranged on the front and rear sides of the middle part of the rack offline mechanism 200. The lifting plate 520 is slidably installed in the vertical frame 510. The second lifting electric cylinder 530 is vertically installed at the top end of the vertical frame 510, and its driving end is connected to the lifting plate 520. The lifting plate 540 is slidably installed at the top end of the lifting plate 520.

Specifically, the vertical frame 510 is installed in the middle of the offline adjustment frame 220 and is connected to the outside of the receiving table 241 in the No. V support assembly 240. The vertical frame 510 is also provided with a sensor for detecting the number of stacking layers.

[0054] During offline transfer, the No. 3 second sliding table 250 transports the loading rack of the No. Ⅳ support assembly 240 to the No. Ⅴ support assembly 240. The driving cylinder 550 drives the lifting plate 540 to longitudinally move towards the loading rack until the lifting plate 540 reaches below the loading rack. Then, the second lifting electric cylinder 530 pulls the lifting plate 520 upwards, thereby driving the overall upward movement of the second lifting electric cylinder 530 and the lifting plate 540, so as to pull the loading rack up by the height of one layer of the loading rack. Then, the No. 3 second sliding table 250 transports another loading rack on the No. Ⅳ support assembly 240 to the No. Ⅴ support assembly 240. The second lifting electric cylinder 530 drives the lifting plate 520 to descend a little height, so that the upper-layer loading rack is stacked on the lower-layer loading rack. Then, the driving cylinder 550 drives the lifting plate 540 to longitudinally move back to its original position, the second lifting electric cylinder 530 drives the lifting plate 520 to descend back to its original position, and the driving cylinder 550 drives the lifting plate 540 to longitudinally move towards the loading rack again until the lifting plate 540 reaches below the lower-layer loading rack. Then, the two-layer loading rack is lifted up by the height of one layer of the loading rack. The No. 3 second sliding table 250 transports another loading rack to the No. Ⅴ support assembly 240 to achieve three-layer stacking. Finally, the No. 4 second sliding table 250 transports the three-layer loading rack stacked on the No. Ⅴ support assembly 240 to the No. Ⅵ support assembly 240, and the forklift forks it away as a whole.
