Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery trays, in particular to a multi-layer storage rack for automobile battery trays. BACKGROUND

[0002] In the field of new energy automobile manufacturing, as a core component, the production and processing of power batteries require high efficiency and precision. As an important bearing structure of battery modules, battery trays need to go through welding, detection, assembly and other processes on the production line. In order to realize the orderly flow between processes, a special storage rack is usually used to transfer the battery trays from the storage area to each processing station.

[0003] At present, the storage rack structure used by most production lines is relatively simple, and usually only a single battery tray can be accommodated, which leads to frequent loading and unloading operations in large-scale continuous production, many times of transfer, long tact time, and greatly affects the production tact. Although some improved racks have a multi-layer structure and can realize vertical stacking and storage of multiple battery trays, such design still has obvious defects: first, multiple battery trays are in a fixed stacking state on the rack, and the positions of each battery tray cannot be flexibly adjusted. When the lower battery tray is processed, the upper tray must be removed first, otherwise it will block the operation space of the processing equipment. This usually requires the use of auxiliary equipment such as mechanical hands and cranes to transfer the upper trays one by one to a temporary storage area or another rack, which not only increases the equipment investment and operating cost, but also complicates the operation process, easily causes waiting time, and reduces the overall work efficiency. The more prominent problem is that as the upper trays are removed one by one, the storage height of the remaining trays on the rack is constantly reduced, and when the tray position is close to the ground, the processing equipment cannot effectively access the work surface, and the operator also needs to bend down or squat for auxiliary operation, which not only affects the processing precision, but also increases the labor intensity, further slows down the production rhythm. SUMMARY

[0004] Therefore, the present application provides a multi-layer storage rack for automobile battery trays, which can overcome the shortcomings of the existing multi-layer storage rack that needs to rely on auxiliary equipment such as mechanical hands and cranes to transfer the upper trays one by one to another rack in order to process the lower trays, and the storage height of the remaining trays on the rack will be constantly reduced.

[0005] The technical scheme is as follows: a multi-layer storage rack for automobile battery trays, comprising: a mobile rack; a double-shaft motor symmetrically installed on the mobile rack; conveying wheels symmetrically rotatably connected to the mobile rack, and the upper conveying wheels being connected with the output shaft of the double-shaft motor; a conveying belt wound between the upper and lower conveying wheels; U-shaped frames uniformly and spacedly connected to the conveying belt; support plates placed between the two U-shaped frames aligned in the longitudinal direction; a moving-out assembly arranged on the mobile rack and used for moving out the upper automobile battery tray; and a supporting assembly arranged on the mobile rack and used for supporting the moved-out automobile battery tray.

[0006] Further, the moving-out assembly comprises: an electric push rod symmetrically installed on the mobile rack; a sliding plate slidably connected to the mobile rack and connected with the telescopic rod of the electric push rod; a fixed frame connected to the top of the sliding plate; lifting clamping rods symmetrically slidably connected to the fixed frame, and the side surface of the support plate is provided with through holes matched with the shape of the end of the lifting clamping rod; and a lifting mechanism arranged on the fixed frame and used for driving the lifting clamping rod to lift.

[0007] Further, the lifting mechanism comprises: a first drive motor symmetrically installed on the bottom of the sliding plate; a first screw rod symmetrically rotatably connected to the sliding plate, the end of the first screw rod being connected with the output shaft of the first drive motor, and the lifting clamping rod being threadedly connected with the first screw rod.

[0008] Further, the supporting assembly comprises: a fixed frame symmetrically connected to the mobile rack; a lifting block slidably connected to the fixed frame, and the two sides of the lifting block being provided with arc surfaces; a second drive motor symmetrically installed on the mobile rack; a second screw rod symmetrically rotatably connected to the mobile rack, the end of the second screw rod being connected with the output shaft of the second drive motor, and the lifting block being threadedly connected with the second screw rod.

[0009] Further, it further comprises: rollers symmetrically rotatably connected to the lifting block.

[0010] Further, it further comprises: a sliding insertion rod slidably connected to the inside of the lifting clamping rod, the sliding insertion rod being symmetrically provided with inclined holes, the inner wall of the through hole being provided with an insertion hole, and the end of the sliding insertion rod being capable of being inserted into the insertion hole; and a moving mechanism arranged on the lifting clamping rod and used for driving the sliding insertion rod to move.

[0011] Further, the moving mechanism comprises: a guide frame connected to the inside of the lifting clamping rod; a lifting plate slidably connected to the guide frame and sliding in the inside of the lifting clamping rod; a connecting spring having two ends respectively connected to the guide frame and the lifting plate; and short rods symmetrically connected to the two sides of the lifting plate and sliding in the inclined holes.

[0012] Further, the limiting column is symmetrically connected to the support plate in sliding mode, and the inner side of the U-shaped frame is symmetrically provided with limiting holes, and the end of the limiting column can be inserted into the limiting hole.

[0013] The beneficial effects are: 1. The vertical arrangement and storage and automatic lifting adjustment of the multi-layer automobile battery tray are realized through the linkage of the double-shaft motor, the conveying wheel, the conveying belt and the U-shaped frame. Meanwhile, through the precise clamping of the lifting clamping rod and the through hole of the support plate, and the support of the lifting block and the roller, the finished tray can be automatically moved out and lowered to the lower layer, without relying on external mechanical hands or temporary racks, which can significantly reduce the transfer time and equipment cost, and improve the production efficiency.

[0014] 2. The sliding insertion rod and the insertion hole of the support plate are matched to ensure the temporary locking of the lifting clamping rod and the support plate when the position is changed, so as to avoid the inclination or slipping of the tray. Meanwhile, the limiting column and the limiting hole of the U-shaped frame form elastic limiting under the action of the reset spring, so as to ensure the stability of the tray during lifting, ensure the operation height of each tray by the processing equipment, and improve the processing precision.

[0027] As shown in Figure 4 and Figure 5 , the supporting assembly comprises fixed frames 14, lifting blocks 15, second drive motors 16, second lead screws 17 and rollers 18, the front part of the moving rack 1 is symmetrically connected with the fixed frames 14, the inside of the two fixed frames 14 is slidably connected with the lifting blocks 15, the upper part of the front and rear sides of the lifting blocks 15 is provided with arc surfaces 1501, the bottom front side of the moving rack 1 is symmetrically provided with the second drive motors 16, the front part of the moving rack 1 is symmetrically rotatably connected with the second lead screws 17, the lower end of the second lead screw 17 is connected with the output shaft of the second drive motor 16, the upper end of the second lead screw 17 is rotatably connected with the fixed frame 14, the lifting block 15 is threadedly connected with the second lead screw 17, the inside of the front and rear sides of the lifting block 15 is rotatably connected with the rollers 18, and the top height of the roller 18 is slightly higher than the top height of the lifting block 15.

[0028] When the device needs to be used, first, two support plates 6 can be respectively placed in the two groups of U-shaped frames 5 on the uppermost side, and the two support plates 6 are horizontally aligned, then an automobile battery tray is placed between the top of the two support plates 6, and then the upper conveying wheel 3 is driven to rotate a specified angle by the double-shaft motor 2, which can drive the conveying belt 4 and the lower conveying wheel 3 to rotate a specified angle, the conveying belt 4 can drive the U-shaped frame 5 to rotate a specified angle, and the U-shaped frame 5 can drive the support plate 6 and the automobile battery tray to descend a specified distance, and the above operation is repeated, so that multiple automobile battery trays can be stored in the mobile rack 1, and the multiple automobile battery trays are vertically arranged.Then the mobile rack 1 can be moved to the processing station, and the mobile rack 1 can drive the automobile battery tray to the processing station, and at this time the uppermost automobile battery tray can be processed. After processing, the first driving motor 12 drives the first lead screw 13 to rotate, and the first lead screw 13 drives the lifting clamp rod 10 to move upwards, so that the rear end of the lifting clamp rod 10 is located in the through hole 11 of the uppermost supporting plate 6. Then the electric push rod 7 drives the sliding plate 8 to move forward, and the sliding plate 8 drives the fixed frame 9 and the lifting clamp rod 10 to move forward. Through the cooperation of the lifting clamp rod 10 and the through hole 11, the lifting clamp rod 10 can pull the uppermost supporting plate 6 to move forward, so that the uppermost supporting plate 6 is separated from the U-shaped frame 5. The uppermost supporting plate 6 drives the processed automobile battery tray to move forward, so that the processed automobile battery tray no longer blocks the upper of the remaining automobile battery trays. When the uppermost supporting plate 6 moves forward, the bottom of the supporting plate 6 will contact the roller 18. The roller 18 can rotate through the friction between the roller 18 and the supporting plate 6, so as to reduce the friction and assist the supporting plate 6 to move forward. At this time, the lifting block 15 and the roller 18 cooperate to support the supporting plate 6. Then the first driving motor 12 drives the first lead screw 13 to reverse, and the first lead screw 13 drives the lifting clamp rod 10 to move downwards. At the same time, the second driving motor 16 drives the second lead screw 17 to reverse, and the second lead screw 17 drives the lifting block 15 to move downwards. The speed of the lifting block 15 and the lifting clamp rod 10 moving downwards is consistent, so as to drive the supporting plate 6 on the lifting block 15 and the processed automobile battery tray to move downwards, so that the above-mentioned supporting plate 6 and the processed automobile battery tray are aligned with the lowermost U-shaped frame 5. Then the double-shaft motor 2 drives the conveying wheel 3, the conveying belt 4 and the U-shaped frame 5 to reverse by a specified angle. The U-shaped frame 5 drives the remaining supporting plates 6 and automobile battery trays to rise by a specified distance, so as to process the next automobile battery tray by the staff. At this time, the electric push rod 7 drives the sliding plate 8 to move backward to reset, and the sliding plate 8 drives the fixed frame 9 and the lifting clamp rod 10 to move backward to reset. Through the cooperation of the lifting clamp rod 10 and the through hole 11, the lifting clamp rod 10 can push the supporting plate 6 on the lifting block 15 and the processed automobile battery tray to move backward, so that the above-mentioned supporting plate 6 slides into the lowermost two groups of U-shaped frames 5. At this time, the above-mentioned supporting plate 6 is separated from the roller 18. Then the second driving motor 16 drives the second lead screw 17 to rotate, and the second lead screw 17 drives the lifting block 15 to move upwards to reset. Thus, the processed automobile battery tray can be automatically moved below the remaining automobile battery trays without the aid of other auxiliary equipment and temporary storage racks, and each automobile battery tray can be processed at the same height.

[0029] Since the rear end of the lifting clamp rod 10 and the through hole 11 on the supporting plate 6 adopt a sliding clamping mode, there is a risk of separation between the supporting plate 6 and the lifting clamp rod 10. Therefore, a temporary connection mechanism is designed, such asFigure 3 、 Figure 6 and Figure 7 As shown in the figure, the temporary connecting mechanism further comprises sliding insertion rods 19 and a moving mechanism, the inner middle part of each of the two lifting clamping rods 10 is slidably connected with a sliding insertion rod 19, the left and right sides of the front part of the sliding insertion rod 19 are provided with inclined holes 1901, the inner wall of the through hole 11 is provided with an insertion hole 20 at the rear side, the rear end of the sliding insertion rod 19 can be inserted into the insertion hole 20, and the lifting clamping rod 10 is provided with a moving mechanism for driving the sliding insertion rod 19 to move; the moving mechanism comprises a guide frame 21, a lifting plate 22, a connecting spring 23 and a short rod 24, the inner upper side of each of the two lifting clamping rods 10 is connected with the guide frame 21, the lifting plate 22 is slidably connected to the guide frame 21, and the lifting plate 22 slides in the lifting clamping rod 10, the front and rear sides of the lower part of the lifting plate 22 are also arc surfaces, the connecting spring 23 is connected between the top of the lifting plate 22 and the guide frame 21, the left and right sides of the front part of the lifting plate 22 are connected with the short rod 24, and the short rod 24 slides in the inclined hole 1901.

[0030] In the initial state, the bottom of the lifting plate 22 is in contact with the top of the roller 18, and the connecting spring 23 is in a compressed state; when the lifting clamping rod 10 moves forward to pull the support plate 6 forward, the lifting clamping rod 10 can drive the lifting plate 22 to move forward, when the lifting plate 22 is separated from the roller 18, the bottom of the lifting plate 22 will be in contact with the top of the lifting block 15, the connecting spring 23 will slightly recover to the original state, and drive the lifting plate 22 to move downward by a distance, with the continuous forward movement of the lifting plate 22, the lifting plate 22 will be separated from the lifting block 15, the connecting spring 23 will completely recover to the original state, and drive the lifting plate 22 to move downward again by a distance, the lifting plate 22 will drive the short rod 24 to move downward when moving downward, the short rod 24 can drive the sliding insertion rod 19 to move backward by extruding the inclined hole 1901, so that the rear end of the sliding insertion rod 19 is inserted into the insertion hole 20, thereby completing the temporary connection between the lifting clamping rod 10 and the support plate 6, the lifting clamping rod 10 and the lifting block 15 can prevent the support plate 6 from tilting or moving when subsequently driving the support plate 6 to move downward, and ensure that the automobile battery tray can be smoothly exchanged; when the lifting clamping rod 10 moves backward to push the support plate 6 backward to reset, the lifting clamping rod 10 can drive the lifting plate 22 to move backward, when the arc surface on the lifting plate 22 is in contact with the arc surface 1501 on the lifting block 15, the lifting plate 22 will be pressed to move upward, and then the lifting plate 22 will be in contact with the roller 18 to be pressed to move upward again, the connecting spring 23 is compressed, the lifting plate 22 drives the short rod 24 to move upward, the short rod 24 can drive the sliding insertion rod 19 to move forward to reset by extruding the inclined hole 1901, so that the rear end of the sliding insertion rod 19 is separated from the insertion hole 20, thereby enabling the lifting clamping rod 10 to be connected with the end of the support plate 6, so that the lifting clamping rod 10 can be temporarily connected with the remaining support plates 6 subsequently.

[0031] As Figure 8As shown, the support plate 6 is internally slidably connected to the limiting column 25, the end of the limiting column 25 away from the support plate 6 is arc-shaped, the upper and lower sides of the inner wall of the U-shaped frame 5 are both provided with limiting holes 26, and the end of the limiting column 25 can be inserted into the limiting hole 26, and the limiting column 25 and the support plate 6 are connected with the reset spring 27.

[0032] When the support plate 6 is placed in the U-shaped frame 5, the limiting hole 26 is vertically aligned with the limiting column 25, under the elastic force of the reset spring 27, the end of the limiting column 25 can be inserted into the limiting hole 26, so that the support plate 6 can be limited, in the process of lifting the support plate 6 by the U-shaped frame 5, the support plate 6 can be prevented from moving randomly and separating from the U-shaped frame 5; when the lifting clamping rod 10 pulls the support plate 6 forward, under the elastic force of the reset spring 27, the limiting column 25 is pressed and can separate from the limiting hole 26, so that the movement of the support plate 6 is not affected.

[0033] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
