Description
Technical Field
[0001] This utility model relates to the field of automated workpiece conveying, and in particular to a liftable automotive battery conveying mechanism. Background Technology
[0002] In automotive battery assembly lines, the long transport distance and complex battery assembly process involve many assembly stations. Due to limited space, many stations require manual operations. The traditional approach is to set up a stopping mechanism at the station where operations are needed to stop the battery pallet, then use a positioning mechanism to position it before proceeding with the operation. This traditional line requires stopping, positioning, and sometimes clamping mechanisms, resulting in a complex overall structure and relatively high manufacturing and maintenance costs. In addition, in some special cases, two production lines need to be set up in the downstream direction of a certain workstation. After the workpiece is processed at this workstation, it needs to be transported to a certain production line according to the actual situation. The traditional approach is to put the two production lines in the downstream direction at the same level and set up a mechanism at this workstation that can drive the pallet (workpiece) to turn. The turning mechanism connects the pallet to a subsequent production line, and finally realizes the distribution of workpieces. However, the structure of the turning mechanism is relatively complex and the cost is high.
[0003] Therefore, a method or apparatus is needed to solve the above problems. Utility Model Content
[0004] This utility model aims to address the aforementioned shortcomings of existing technologies by proposing a liftable automotive battery transport mechanism that features a simple structure, ingenious design, and reasonable layout. This mechanism can drive the pallet and workpiece to change their height longitudinally for pallet positioning or to facilitate the transport of the pallet to two lines at different heights.
[0005] The technical solution of this utility model is: a liftable automotive battery conveying mechanism, characterized in that: the conveying mechanism includes a support frame 1, a lifting drive motor 2 is arranged in the middle of the support frame 1, the output end of the lifting drive motor 2 is connected to the input end of a gearbox 3, and the output end of the gearbox 3 is connected to a first lifting drive wheel 5 and a second lifting drive wheel 6 respectively through two sets of pulley transmission pairs 4. The first lifting drive wheel 5 is arranged on a first lifting shaft 7, and the second lifting drive wheel 6 is arranged on a second lifting shaft 8. Both the first lifting shaft 7 and the second lifting shaft 8 are rotatably connected to the support frame 1. At the same time, cam mechanisms are arranged at both ends of the first lifting shaft 7 and the second lifting shaft 8, and guide mechanisms are arranged at both ends of the support frame 1. The conveying mechanism also includes a conveying frame 9. Multiple pairs of equally spaced conveying rollers 11 are arranged in the two side frames 10 of the conveying frame 9, and adjacent conveying rollers 11 are connected to each other through a belt pulley drive pair. A conveying motor 12 is arranged on the outside of one side frame 10. The output end of the conveying motor 12 is connected to the conveying drive shaft 13. A pair of conveying rollers 11 are arranged on the conveying drive shaft 13. Guide posts 14 are respectively arranged at both ends of the conveying frame 9. The guide posts 14 are matched with the guiding mechanism.
[0006] The cam mechanism includes a rectangular block 15 connected to a first lifting shaft 7 or a second lifting shaft 8. A support wheel 16 is provided on the rectangular block 15. The central axis of the support wheel 16 does not pass through the centroid of the rectangular block 15, and the support wheel 16 can contact the bottom of the conveying frame 9.
[0007] The second lifting shaft 8 is provided with a first trigger plate 17 and a second trigger plate 18, and the support frame 1 is provided with a first sensor 19 and a second sensor 20.

[0009] The support shafts of the two guide wheels 22 are perpendicular to each other.
[0010] Compared with the prior art, this utility model has the following advantages: This type of liftable automotive battery conveying mechanism features a simple structure, ingenious design, and rational layout. Addressing the problems encountered in traditional automated conveyor lines during actual operation, it employs a unique structure consisting of a relatively fixed support frame at the bottom and a conveyor frame at the top that can move relative to the fixed frame. A cam mechanism is installed on the support frame, which, in conjunction with a guide mechanism, drives the conveyor frame above to move longitudinally. This changes the horizontal height of multiple pairs of conveyor rollers on the conveyor frame, enabling the positioning of the conveyed pallets or the distribution of different lines. Compared to traditional positioning methods and traditional line distribution structures, this conveying mechanism is relatively simple in structure, offering advantages such as reliable positioning, rapid response, compact structure, and small footprint. Furthermore, its manufacturing process is simple and cost-effective. Therefore, it possesses numerous advantages, making it particularly suitable for widespread application in this field, with a very broad market prospect. Attached Figure Description

[0014] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figure 1 , Figure 2 , Figure 3 The diagram shows a liftable automotive battery delivery mechanism, comprising a support frame 1. A lifting drive motor 2 is disposed in the middle of the support frame 1. The output end of the lifting drive motor 2 is connected to the input end of a gearbox 3. The output end of the gearbox 3 is connected to a first lifting drive wheel 5 and a second lifting drive wheel 6 respectively via two sets of pulley transmission pairs 4. The first lifting drive wheel 5 is disposed on a first lifting shaft 7, and the second lifting drive wheel 6 is disposed on a second lifting shaft 8. Both the first lifting shaft 7 and the second lifting shaft 8 are rotatably connected to the support frame 1. Cam mechanisms are disposed at both ends of the first lifting shaft 7 and the second lifting shaft 8, and guide mechanisms are disposed at both ends of the support frame 1. The conveying mechanism also includes a conveying frame 9. Multiple pairs of equally spaced conveying rollers 11 are arranged in the two side frames 10 of the conveying frame 9, and adjacent conveying rollers 11 are connected to each other through a belt pulley drive pair. A conveying motor 12 is arranged on the outside of one side frame 10. The output end of the conveying motor 12 is connected to the conveying drive shaft 13. A pair of conveying rollers 11 are arranged on the conveying drive shaft 13. Guide posts 14 are respectively arranged at both ends of the conveying frame 9. The guide posts 14 are matched with the guiding mechanism.
[0015] The cam mechanism includes a rectangular block 15 connected to a first lifting shaft 7 or a second lifting shaft 8. A support wheel 16 is provided on the rectangular block 15. The central axis of the support wheel 16 does not pass through the centroid of the rectangular block 15, and the support wheel 16 can contact the bottom of the conveying frame 9.
[0016] The second lifting shaft 8 is provided with a first trigger plate 17 and a second trigger plate 18, and the support frame 1 is provided with a first sensor 19 and a second sensor 20. When the first trigger plate 17 triggers the first sensor 19, the conveying frame 9 is in a low position, and when the second trigger plate 18 triggers the second sensor 20, the conveying frame 9 is in a high position.
[0017] The guiding mechanism includes two upright plates 21 that are fixedly connected to the support frame 1. The top of the upright plates 21 is provided with guide wheels 22, and the two guide wheels 22 can simultaneously contact the outer wall of the guide column 14.
[0018] The support shafts of the two guide wheels 22 are perpendicular to each other.
[0019] The working process of the liftable automotive battery delivery mechanism in this embodiment of the utility model is as follows: Example 1
[0020] Under normal operating conditions, the conveying frame 9 in this conveying mechanism is in a relatively high position. At this time, the horizontal height of the conveying frame 9 is consistent with the height of the line body in front of and behind it. The pallet loaded with the workpiece (battery) enters the device from the incoming material direction, specifically, it moves onto the conveying frame 9. Then, the control system sends a signal to the lifting drive motor 2 in this device. The lifting drive motor 2 drives the first lifting drive wheel 5 (and the first lifting shaft 7) and the second lifting drive wheel 6 (and the second lifting shaft 8) to rotate through the belt pulley transmission pair 4. When the two lifting shafts rotate, they will drive the cam mechanism on them to move. The rectangular block 15 in the cam mechanism rotates, and the support wheel 16 swings from the high position to the low position and disengages from the contact with the conveying frame 9. At this time, the conveying frame 9 is supported by the support frame 1 itself. At the same time, the first trigger plate 17 triggers the first sensor 19. During the above process, under the guidance of the guide column 14 and the guiding mechanism, the conveying frame 9 can only move longitudinally relative to the support frame 1, and the horizontal position of the two cannot be changed. As the pallet descends with the movement of the conveyor frame 9, positioning components such as positioning pins and positioning posts on the support frame 1 will be inserted into the positioning holes on the pallet, and the pallet will be positioned. Then, the battery can be processed in the current state. After processing, the lifting drive motor 2 starts working again, the first lifting shaft 7 and the second lifting shaft 8 rotate until the second trigger plate 18 triggers the second sensor 20. At this time, the conveying frame 9 returns to the high position and the tray regains its freedom. Then the conveying motor 12 starts working, driving all the conveying rollers 11 to rotate and convey the tray (and the battery) to the line set in the exit direction. Example 2
[0021] Initially, the conveyor frame 9 in this conveying mechanism is at a relatively high position. At this time, the horizontal height of the conveyor frame 9 is consistent with the height of the conveyor line in front of it. Behind the conveyor frame 9 (in the discharge direction), there are two stacked conveyor lines of different heights: the upper one, line A, and the lower one, line B. These two conveyor lines correspond to two different processing paths. The pallet loaded with the workpiece (battery) enters the device from the incoming material direction, specifically moving onto the conveyor frame 9. When the workpiece needs to be transported to line A, the conveyor motor 12 works, driving all the conveyor rollers 11 to rotate and directly transport the pallet to line A. When the workpiece needs to be transported to line B, the control system sends a signal to the lifting drive motor 2 in this device. The lifting drive motor 2 drives the first lifting drive wheel 5 (and the first lifting shaft 7) and the second lifting drive wheel 6 (and the second lifting shaft 8) to rotate through the belt pulley transmission pair 4. When the two lifting shafts rotate, they will drive the cam mechanism on them to move. The rectangular block 15 in the cam mechanism rotates, and the support wheel 16 swings from the high position to the low position and disengages from the contact with the conveying frame 9. At this time, the conveying frame 9 is supported by the support frame 1 itself, and at the same time, the first trigger plate 17 triggers the first sensor 19. During the above process, under the guidance of the guide column 14 and the guiding mechanism, the conveying frame 9 can only move longitudinally relative to the support frame 1, and the horizontal position of the two cannot be changed. At this time, the horizontal height of the conveyor frame 9 is consistent with the height of the B line. It is only necessary to send a signal to the conveyor motor 12, and the conveyor motor 12 drives all the conveyor rollers 11 to rotate, conveying the pallet into the B line. After the movement is completed, the conveyor frame 9 rises back to the high position to facilitate the receiving of the next pallet.
[0022] It should be noted that even if the conveying frame 9 is in a relatively low position, the guide mechanism set on the support frame 1 will not affect the horizontal movement of the conveying frame 9.
