Description

Technical Field

[0001] The utility model belongs to the field of grid production equipment, and particularly relates to a grid stacking and sheet collecting mechanism. Background Art

[0002] After the battery grid is sliced and manufactured, it needs to be sheet-collected. The sheet-collecting process usually stacks the grids into grid stacks by manually stacking them according to the specified number of sheets, or the grids are sequentially conveyed by a conveyor belt and dropped onto a receiving platform to stack into grid stacks, and then the grid stacks are placed into a storage box. However, the method of manually stacking grid stacks has a low degree of mechanization, which greatly affects the working efficiency of grid stacking and sheet collecting; the method of stacking with the help of a conveyor belt results in poor neatness between grid sheets, the grid stacks are prone to collapse, and the number of grid sheets in each grid stack cannot be controlled. It is necessary to stop the machine to take out the grid stack, and the downtime is long, which affects the working efficiency. Moreover, due to the poor neatness between grid sheets, the utilization rate of the space in the storage box by the grid stacks is greatly reduced. Therefore, how to further improve the degree of mechanization of the grid stacking and sheet collecting work, reduce manual participation, improve the working efficiency and make the grid stacks stacked neatly is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0003] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a grid stacking and sheet collecting mechanism, which can realize the mechanical automation of the grid stacking and sheet collecting work, reduce the degree of human participation, and improve the working efficiency and the neatness of grid stacking.

[0004] The specific technical solution adopted by the utility model is as follows:

[0005] A grid stacking and sheet collecting mechanism includes a frame, a feeding belt, a receiving unit and a discharging belt which are sequentially arranged on the frame along the conveying direction of the grid. The receiving unit includes a vertical baffle, a lifting driving unit and a lifting horizontal plate connected to the driving end of the lifting driving unit. The lifting horizontal plate and the vertical baffle cooperate to form a grid accommodating seat. The grid accommodating seat is connected to the output end of the feeding belt to form a grid stack, and the grid accommodating seat is connected to the feeding end of the discharging belt to discharge the grid stack.

[0006] The output end of the feeding belt is higher than the feeding end of the discharging belt.

[0007] The receiving unit further includes a transverse movement driving unit connected to the lifting driving unit. A lifting support plate is further arranged on the frame and is arranged in an intersecting manner with the discharging belt. The lifting support plate and the lifting horizontal plate are arranged in an intersecting manner. The lifting horizontal plate has the freedom to withdraw between the lifting support plates by means of the transverse movement driving unit.

[0008] The lifting drive unit described is an electric slide table connected to the frame and arranged longitudinally. The transverse movement drive unit is a transverse cylinder connected to the drive end of the electric slide table. The lifting horizontal plate is connected to the drive end of the transverse cylinder.

[0009] The vertical baffle and the lifting horizontal plate are of a split structure. The vertical baffle is a comb-shaped structure connected to the frame. The lifting horizontal plate is inserted into the tooth gaps of the comb-shaped structure and has the freedom to move between the tooth gaps by means of the drive of the lifting drive unit.

[0010] The feeding belt includes a first support frame and a conveyor chain arranged on the first support frame. One end of the first support frame is hinged to the frame, and the other end is connected to the frame by means of a first telescopic cylinder. The first support frame has the freedom to adjust the inclination angle of the conveyor chain by means of the telescopic movement of the first telescopic cylinder.

[0011] On both sides of the conveyor chain, there are retaining belts that contact the edge of the grid and assist the grid to be conveyed along the conveyor chain.

[0012] The driving roller of the conveyor chain is located at the output end of the conveyor chain. On the first support frame, there is a pressure roller located above the driving roller and matching the conveyor chain.

[0013] On the frame, there is also a receiving belt connected to the input end of the feeding belt. The receiving belt includes a second support frame and a receiving chain arranged on the second support frame. One end of the second support frame is hinged to the frame, and the other end is connected to the frame by means of a second telescopic cylinder. The second support frame has the freedom to adjust the inclination angle of the receiving chain by means of the telescopic movement of the second telescopic cylinder.

[0014] Below the receiving belt, there is a waste material receiving conveyor belt with an inclined conveying direction. At the end of the waste material receiving conveyor belt, there is a waste material collection box.

[0015] The beneficial effects of the present utility model are as follows:

[0016] In the present utility model, a liftable lifting horizontal plate is used in cooperation with a vertical baffle to receive the grids output by the feeding belt. A grid receiving seat is formed between the lifting horizontal plate and the vertical baffle. As the number of received grids increases, the grid receiving seat gradually moves downward, reducing the dropping height of the grids output by the feeding belt in the air, ensuring that the grids can fall smoothly onto the grid receiving seat, preventing the grids from bouncing and dropping, and effectively improving the neatness of the stack of grids on the grid receiving seat; improving the mechanization degree of grid stacking and collecting, and reducing the degree of manual participation;

[0017] The output end of the feeding belt is higher than the feeding end of the discharging belt. The material receiving unit does not need to turn, and by lifting the lifting horizontal plate, the grid accommodating seat can reciprocally connect with the output end of the feeding belt and the feeding end of the discharging belt, optimizing the moving path of the material receiving unit;

[0018] A lifting support plate intersecting with the discharging belt is further arranged on the frame. The lifting horizontal plate is also connected to the transverse movement driving unit. The lifting support plate is used to support the stack of grids on the grid accommodating seat. The lifting horizontal plate withdraws between the lifting support plates by means of the transverse movement driving unit, and the grid accommodating seat is separated from the stack of grids. The grids output by the feeding belt fall onto the lifting support plate to continue forming a stack of grids; and the lifting horizontal plate rises to the initial height by means of the lifting driving unit, and the transverse movement driving unit drives the lifting horizontal plate to move transversely to the initial position. The grid accommodating seat continues to receive materials. While the grid accommodating seat is receiving materials, the lifting support plate descends to place the stack of grids on the discharging belt, and the stack of grids is conveyed by the discharging belt; the vertical baffle blocks the stack of grids to prevent the stack of grids from collapsing as the lifting horizontal plate moves transversely; the setting of the lifting support plate shortens the lifting height of the lifting horizontal plate, which helps to improve the working efficiency and the smoothness of the movement of the lifting horizontal plate.

Detailed Embodiments

[0024] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0025] Specific embodiments, such as Figures 1-4As shown in the figure, a grid stack receiving mechanism includes a frame 1, a feeding belt 2, a receiving unit, and a discharging belt 3 that are sequentially arranged on the frame 1 along the conveying direction of the grid. The receiving unit includes a vertical baffle 4, a lifting drive unit 5, and a lifting horizontal plate 6 connected to the drive end of the lifting drive unit 5. The lifting horizontal plate 6 and the vertical baffle 4 cooperate to form a grid receiving seat 7. The grid receiving seat 7 is connected to the output end of the feeding belt 2 to form a grid stack 8, and the grid receiving seat 7 is connected to the feeding end of the discharging belt 3 to discharge the grid stack 8.

[0026] During operation, the lifting drive unit 5 drives the lifting horizontal plate 6 to rise and fall, thereby realizing the lifting of the grid receiving seat 7. The grids output by the feeding belt 2 fall onto the lifting horizontal plate 6. The vertical baffle 4 limits the movement of the grids output by the feeding belt 2 in the horizontal position to prevent the grids from generating displacement on the lifting horizontal plate 6 due to inertia. The lifting horizontal plate 6 and the vertical baffle 4 work together to form a relatively neat grid stack 8 on the lifting horizontal plate 6, that is, the grid receiving seat 7 formed by the cooperation of the lifting horizontal plate 6 and the vertical baffle 4 receives the grid stack 6 formed by the grids.

[0027] The grid receiving seat 7 is connected to the output end of the feeding belt 2 to receive the grids output by the feeding belt 2. By means of the lifting of the lifting horizontal plate 6, the grid receiving seat 7 gradually descends as the number of received grids increases, preventing the grids from bouncing and tilting on the grid receiving seat 7 when the grid receiving seat 7 initially receives materials due to the too large dropping distance of the grids from the feeding belt 2 to the grid receiving seat 7. When the grids on the grid receiving seat 7 reach the preset quantity, the grid receiving seat 7 is connected to the feeding end of the discharging belt 3, and the grid stack 6 continues to be transported by the discharging belt 3. Subsequently, the lifting horizontal plate 5 resets to enable the grid receiving seat 7 to receive materials again.

[0028] The output end of the feeding belt 2 is higher than the feeding end of the discharging belt 3. The lifting horizontal plate 5 can make the grid receiving seat 7 reciprocally connect with the output end of the feeding belt and the feeding end of the discharging belt through lifting, which helps to optimize the movement path of the receiving unit and the overall layout of the receiving mechanism.

[0029] The receiving unit further includes a transverse movement drive unit 9 connected to the lifting drive unit 5. A lifting support plate 10 is also arranged on the frame 1 and is arranged in an intersecting manner with the discharging belt 3. The lifting support plate 10 and the lifting horizontal plate 6 are arranged in an intersecting manner. The lifting horizontal plate 6 has the freedom to withdraw between the lifting support plates 10 by means of the transverse movement drive unit 9.

[0030] When the grid holder 7 receives materials, the lifting pallet 10 rises, and the grid holder 7 gradually descends. The lifting pallet 10 inserts between the lifting horizontal plates 6 to support the stack of grids on the grid holder 7. The lifting horizontal plates 6 move horizontally by means of the transverse movement drive unit 9 to form a reverse movement with the lifting pallet 10, so as to withdraw from between the lifting pallets 10. The lifting pallet 10 continues to receive the grids output on the feeding belt 2. At this time, the lifting horizontal plates 6 rise by means of the lifting drive unit 5, and the transverse movement drive unit 9 drives the lifting horizontal plates 6 to reset and reform the grid holder 7 with the vertical baffle 4 to receive materials, while the lifting pallet 10 descends to place the stack of grids 8 on it on the discharging belt 3. There is no need for the lifting horizontal plates 6 to descend below the discharging belt 3 to place the stack of grids 8 on the discharging belt 3, shortening the descending distance of the lifting horizontal plates 6. The lifting pallet 10 serves as a transfer unit to make the process of the stack of grids 8 falling on the discharging belt 3 synchronized with the process of the lifting horizontal plates 5 resetting, effectively improving the working efficiency of stacking and receiving the sheets.

[0031] Furthermore, the lifting drive unit 5 is an electric slide table connected to the frame 1 and arranged longitudinally, and the transverse movement drive unit 9 is a transverse cylinder connected to the drive end of the electric slide table. The lifting horizontal plates 6 are connected to the drive end of the transverse cylinder. The electric slide table drives the transverse cylinder to lift and lower. When the transverse cylinder lifts and lowers, it carries the lifting horizontal plates 6 to lift and lower, and the transverse cylinder can drive the lifting horizontal plates 6 to move horizontally by telescoping.

[0032] The vertical baffle 4 and the lifting horizontal plates 6 are of a split structure. The vertical baffle 4 is a comb-shaped structure connected to the frame 1. The lifting horizontal plates 6 are inserted into the tooth gaps of the comb-shaped structure and have the freedom to move between the tooth gaps by means of the drive of the lifting drive unit 5. The vertical baffle 4 is connected to the frame 1. During the descending process of the lifting horizontal plates 6, the grid holder 7 is always formed with the vertical baffle 4. The lifting drive unit 5 and the transverse movement drive unit 9 do not need to drive the vertical baffle 4 to move, reducing the load of lifting and transverse movement. On the other hand, during the process of the lifting pallet 10 rising to receive materials, it also cooperates with the vertical baffle 4 to receive materials, preventing the stack of grids from being disorderly and inclined, which helps to optimize the movement path of the lifting horizontal plates 6 and improve the working efficiency.

[0033] The feeding belt 2 includes a first support frame 11 and a transmission chain 12 arranged on the first support frame 11. One end of the first support frame 11 is hinged to the frame 1, and the other end is connected to the frame 1 by means of a first telescopic cylinder 13. The first support frame 11 has the freedom to adjust the inclination angle of the transmission chain 12 by means of the telescopic length of the first telescopic cylinder 13. By adjusting the telescopic length of the first telescopic cylinder 13, the inclination angle of the feeding belt 2 is adjusted to prevent the grids from generating relative displacement with the feeding belt 2 due to inertia when being sent onto the feeding belt 2, especially when being thrown onto the feeding belt 2, and can enable the grids to perform an obliquely upward projectile motion to leave the output end of the feeding belt 2 and smoothly fall on the grid holder 7.

[0034] In this embodiment, there are two conveyor lines, that is, two groups of conveyor chains 12 are set on the feed belt 2, and two groups of discharge chains are set on the discharge belt 3, which can stack and collect two groups of grids at the same time. In each conveyor line, the number of a group of discharge chains is the third, and the horizontal lifting plate 6 includes three cross plates, and the three cross plates are aligned with the discharge chains up and down, and the lifting support plate 10 is respectively located in the gap between the three discharge chains. The lifting support plate 10 has the degree of lifting freedom by means of the lifter installed on the frame 1. The lifter is a threaded sleeve connected to the motor transmission and a screw screwed with the threaded sleeve, and the lifting support plate 10 is connected to the screw.

[0035] On both sides of the conveyor chain 12, there are provided belts 14 that contact the edges of the grid and assist the grid to be transported along the conveyor chain 12. The belts 14 align the grid on the conveyor chain 12 and prevent the grid from sliding up and down on the inclined conveyor chain 12, so that the conveyor chain 12 can smoothly transport the grid.

[0036] A counting sensor is also provided above the conveyor chain 12 for counting the number of grids output by the conveyor chain 12 , thereby ensuring that the number of grids in the grid stack transported on the discharge belt 3 is consistent.

[0037] Furthermore, the active roller 15 of the conveyor chain 12 is located at the output end of the conveyor chain 12, and the first support frame 11 is provided with a pressure roller 16 located above the active roller 15 and matching the conveyor chain 12. The pressure roller 16 cooperates with the conveyor chain 12 on the active roller 15 to limit the grid to prevent the front end of the grid from falling when it is output at the output end of the conveyor chain 12, ensuring that the grid can be thrown out along the conveying direction of the conveyor chain 12, so that the grid stack formed by the stacked grids is more neat.

[0038] Furthermore, the frame 1 is also provided with a receiving belt 19 connected to the input end of the feeding belt 2, and the receiving belt 19 includes a second support frame 20 and a receiving chain 21 arranged on the second support frame 20. One end of the second support frame 20 is hinged to the frame 1, and the other end is connected to the frame 1 by means of a second telescopic cylinder 22. The second support frame 20 has the freedom to adjust the inclination angle of the receiving chain 21 by means of the extension and contraction of the second telescopic cylinder 22. In this embodiment, one end of the second support frame 20 is hinged to the first support frame 11, and the other end is connected to the first support frame 11 by means of a second telescopic cylinder 22, thereby realizing the connection between the second support frame 20 and the frame 1, and the conveying speed of the conveying chain 12 is greater than the conveying speed of the receiving chain 21, and the input end of the conveying chain 12 and the output end of the receiving chain 21 are interlaced. When working, the receiving belt 19 receives the plate grid punched and formed by the previous workstation and conveys the plate grid to the conveying chain 12, and the conveying speed of the receiving chain 21 can be adjusted separately to the conveying speed of the conveying chain 12, so that the conveying speeds between the two are adapted, thereby realizing smooth conveying of the plate grid on the feeding belt 2.

[0039] The previous station conveys the grids by means of a conveyor belt. Therefore, there are rollers of the conveyor belt at the output end of the previous station. A connecting roller 23 is also provided on the frame 1. The connecting roller 23 is located between the roller at the input end of the material receiving chain 21 and the roller at the output end of the previous station. The connecting roller 23 supports the grids output from the previous station to the material receiving chain 21, reduces the gap between the above two rollers, and prevents the end of the grid from being inserted between the two rollers.

[0040] After the grid roll is changed, the grids formed by punching the front end of the grid roll are prone to defective products. The second telescopic cylinder 22 extends to lift the input end of the material receiving chain 21, and the defective grids output from the previous station fall off and will not be sent to the feeding belt 2 by the material receiving chain 21, preventing defective products from appearing in the grid stack.

[0041] Furthermore, a waste material receiving conveyor belt 17 with an inclined conveying direction is arranged below the material receiving belt 19. A waste material collection box 18 is arranged at the end of the waste material receiving conveyor belt 17. When the input end of the material receiving chain 21 is lifted, the defective grids output from the previous station fall on the waste material receiving conveyor belt 17, and the waste material receiving conveyor belt 17 conveys the defective grids to the waste material collection box 18 for collection and reuse, preventing the defective grids from falling on the ground to form a safety hazard and at the same time reducing the workload of manually collecting the defective grids.
