High-stability battery stacking device

Abstract

The invention provides a high-stability battery stacking device. A driving mechanism is combined with a clamping mechanism to place to-be-stacked batteries into a bearing cylinder and bear the to-be-stacked batteries on a bearing block. The two driving assemblies work at the same time, specifically, the lead screw motor drives the bearing block to move up and down in the bearing cylinder through the driving block and the driving connecting rod so as to bear the to-be-stacked batteries. It needs to be explained that the batteries to be stacked are matched with the bearing cylinder. In the process of carrying the to-be-stacked batteries, when the carrying block is driven to the topmost part, the carrying block carries the first to-be-stacked battery. When the bearing block is driven to the bottommost part, the bearing block bears the last to-be-stacked battery, and after bearing is completed, all the batteries are stacked in the bearing cylinder. And the two driving assemblies drive the bearing block to the topmost part, and the stacked batteries are ejected out of the bearing cylinder so as to be transported and carried conveniently. The high-stability battery stacking device is high in battery stacking height and high in efficiency.

The driving mechanism drives the clamping mechanism 100 to move, and the clamping mechanism 100 is used to clamp, take or place the stacked batteries.

[0024] The receiving mechanism 200 includes a receiving tube 210, a receiving block 220 and two driving assemblies 230.

The receiving block 220 is adapted to the receiving tube 210, and the receiving block 220 is inserted into the receiving tube 210 and slidably connected with the receiving tube 210.

The driving connecting rod 233 is adapted to the slideway 201 , passes through the slideway 201 and is slidably connected to the receiving tube 210 .

[0025] The driving mechanism, the clamping mechanism 100 and the two screw motors 231 are all electrically connected to the control mechanism. It should be noted that in the present embodiment, the control mechanism is a lower computer, specifically, the control mechanism is a PLC. In another embodiment, the control mechanism is a single chip microcomputer. In other embodiments, the control mechanism includes an upper computer and a lower computer, and the upper computer is electrically connected to the lower computer. The control mechanism can control the driving mechanism, the clamping mechanism 100 and the two screw motors 231 to work in coordination to increase the structural strength and structural stability of the high-stability battery stacking device 10.

[0026] In order to avoid mutual wear between the receiving block 220 and the battery. In one embodiment, a buffer pad (not shown) is provided on the top of the receiving block 220, which can buffer the pressure between the receiving block 220 and the battery, avoid direct hard contact between the receiving block 220 and the battery, and avoid mutual wear between the receiving block 220 and the battery. In this embodiment, the buffer pad is a soft rubber pad, which has certain elasticity, good toughness and excellent anti-slip performance.

In this way, the buffer pad provided on the top of the receiving block 220 can avoid mutual wear between the receiving block 220 and the battery.

[0027] During the operation of the high-stability battery stacking device 10, the control mechanism controls the driving mechanism, the clamping mechanism 100 and the two screw motors 231 to work in coordination. The driving mechanism combines with the clamping mechanism 100 to place the battery to be stacked in the receiving tube 210 and receive it on the receiving block 220. The two driving assemblies 230 work simultaneously. Specifically, the screw motor 231 drives the receiving block 220 to move up and down in the receiving tube 210 through the driving block 232 and the driving connecting rod 233 to receive the battery to be stacked. It should be noted that the battery to be stacked is adapted to the receiving tube 210. In the process of receiving the battery to be stacked, when the receiving block 220 is driven to the top, the receiving block 220 receives the first battery to be stacked. When the receiving block 220 is driven to the bottom, the receiving block 220 receives the last battery to be stacked. After receiving, each battery is stacked in the receiving tube 210. The two driving assemblies 230 drive the receiving block 220 to the top, and push the stacked batteries out of the receiving tube 210 for easy transportation.

[0028] In order to improve the safety performance of the high-stability battery stacking device 10, in one embodiment, the high-stability battery stacking device 10 also includes a fire extinguishing mechanism 300, which includes a water tank 310, a water pump 320 and a pumping hose 330.

A plurality of water outlet holes 202 are provided on the inner wall of the receiving cylinder 210, and each water outlet hole 202 is communicated with the diversion cavity. The water inlet 211 is communicated with the diversion cavity. The water pump 320 is communicated with the water inlet 211 through the pumping hose 330. When the battery in the receiving tube 210 catches fire, the water pump 320 pumps the water in the water tank 310 to the water inlet 211 through the pumping hose 330, so that the water enters the diversion cavity through the water inlet 211 and is finally discharged through the water outlet holes 202 to extinguish the fire of the battery in the receiving tube 210. In this way, the fire extinguishing mechanism 300 improves the safety performance of the high-stability battery stacking device 10.

The first driving cylinder 121 is connected to the inner wall of the sealed end of the U-shaped connecting plate 110, and the first driving cylinder 121 is drivingly connected to the first driving plate 122. The vacuum generator 123 is connected to the vacuum adsorption nozzle 125 through the vacuum tube 124. The vacuum adsorption nozzle 125 is arranged on the side of the first driving plate 122 facing away from the first driving cylinder 121. The first driving cylinder 121 and the vacuum generator 123 are both electrically connected to the control mechanism. When the clamping mechanism 100 is working, the driving end of the driving mechanism is connected to the outer wall of the sealed end of the U-shaped connecting plate 110, and the driving mechanism drives the U-shaped connecting plate 110 to the top of the battery. The first driving cylinder 121 presses the vacuum suction nozzle 125 against the top of the battery through the first driving plate 122. At the same time, the vacuum generator 123 works, and the vacuum suction nozzle 125 is placed in a vacuum environment through the vacuum tube 124, and the top of the battery is adsorbed and fixed under the action of atmospheric pressure. In this way, the clamping stability of the clamping mechanism 100 on the battery is increased.

[0030] In order to further increase the clamping stability of the clamping mechanism 100 on the battery, in one embodiment, the clamping mechanism 100 also includes two clamping assemblies 130, and the two clamping assemblies 130 are symmetrically arranged on both sides of the U-shaped connecting plate 110.

The driving shaft of the second driving cylinder 132 passes through the first sliding hole 101 and is driven and connected to the receiving frame 133. A second sliding hole 102 is opened at one end of the receiving frame 133 away from the second driving cylinder 132. The limiting plate 135 is accommodated in the receiving frame 133, the first sliding column 134 is adapted to the second sliding hole 102, one end of the first sliding column 134 passes through the second sliding hole 102 and is connected to the limiting plate 135. The end of the first sliding column 134 away from the limiting plate 135 is connected to the extrusion plate 137. The compression spring 136 is adapted to the first sliding column 134, the compression spring 136 is sleeved on the first sliding column 134, one end of the compression spring 136 is connected to the receiving frame 133, and the end of the compression spring 136 away from the receiving frame 133 is connected to the extrusion plate 137. The side of the extrusion plate 137 facing away from the compression spring 136 is provided with an anti-slip pad 138. The driving mechanism covers the U-shaped connecting plate 110 on the battery, and the two clamping assemblies 130 work simultaneously. The second driving cylinder 132 drives the extrusion plate 137 to move close to or away from the other extrusion plate 137 through the receiving frame 133 and the compression spring 136. The second driving cylinder 132 squeezes and fixes the squeezing plate 137 to the side wall of the battery through the receiving frame 133 and the compression spring 136. The compression spring 136 buffers the impact force between the squeezing plate 137 and the battery, preventing the battery from being damaged by excessive pressure. The two clamping assemblies 130 work together to clamp and fix the battery. In this way, the two clamping assemblies 130 further increase the clamping stability of the clamping mechanism 100 on the battery.

[0031] In order to further increase the clamping stability of the clamping mechanism 100 on the battery, in one embodiment, the clamping mechanism 100 also includes two receiving components 140, and the two receiving components 140 are symmetrically arranged on both sides of the open end of the U-shaped connecting plate 110. The third sliding holes 103 are symmetrically opened on both sides of the open end of the U-shaped connecting plate 110.

When the first driving cylinder 121 lifts the battery through the first driving plate 122 and the vacuum suction nozzle 125, the two receiving components 140 work simultaneously. Specifically, the third driving cylinder 141 drives the bottom of the receiving plate 143 paper battery through the second driving plate 142, so that the receiving plate 143 supports the bottom of the battery. In this way, the two receiving components 140 further increase the clamping stability of the clamping mechanism 100 on the battery.
