Description

Technical Field

[0001] The invention relates to the technical field of transport equipment, in particular to a rolled battery core transport trolley. Background Art

[0002] At present, when using the common rolled battery cell (i.e., core) transport trolley, it is necessary to manually transport the core to the hanging shaft and hold the core steady. Another worker pushes the trolley to the side of the production equipment and turns the trolley lifting switch. The hydraulic system can adjust the hanging shaft. Then the worker needs to swing the trolley to dock with the equipment left and right. After adjusting to the appropriate position, the core is pushed into the equipment using the rollers at the front end of the hanging shaft. During the transportation process, the core is not fixed and only relies on the workers' hand support, which will cause safety hazards. When docking with the equipment, it also relies on the workers to aim and dock, which is not accurate and affects production efficiency. In addition, at least two workers are required to operate during the operation, which wastes manpower. Summary of the invention

[0003] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a rolled battery cell transport trolley, which can fix the core during the transportation process, is safer to use and has higher production efficiency.

[0004] The technical solution adopted by the present invention is as follows: a rolled battery cell transport trolley comprises a mounting frame, which is fixed on a multi-directional movable slide, and a movable plate is arranged on the mounting frame, and the movable plate is driven by a driving mechanism to realize left and right bidirectional movement, and a fixed shaft is cantilevered outwardly on the mounting frame, and the axial length direction of the fixed shaft is the same as the moving direction of the movable plate, and a movable block is embedded in the shaft body of the fixed shaft, and when the movable plate moves left and right, the movable block is driven by a cam mechanism to move radially so that the movable block is hidden inside the fixed shaft or protrudes outside the outer peripheral surface of the fixed shaft, and when loading, the fixed shaft is inserted inside the roll core and the movable block is against the inner wall of the roll core to realize locking; when unloading, the movable block is hidden inside the fixed shaft and the movable plate can push the roll core away from the fixed shaft.

[0005] As a further improvement of the above technical solution:

[0006] The driving mechanism includes a large handwheel and a synchronous belt driven by the large handwheel. The movable plate is arranged horizontally. One side of the movable plate is connected to the synchronous belt through a first connecting plate. The bidirectional rotation of the large handwheel drives the bidirectional rotation of the synchronous belt to realize the left and right bidirectional movement of the movable plate.

[0007] The first limit plate and the second limit plate are connected together by a first slider and a second slider, and the second limit plate is connected with the second linear guide rail to form a limit fit. A limit column is vertically fixed on the plate surface of one end of the second limit plate, and a limit hole is opened in the first limit plate, and the limit hole is a strip hole in the left and right directions and one end of the hole is bent downward. The movable plate is connected to the first limit plate through the second connecting plate, and the limit column is inserted into the bent end inside the limit hole. When the movable plate drives the first limit plate to move left and right along the first linear guide, the first limit plate drives the second limit plate to move up and down along the second linear guide through the limit column, and the movable block is fixed at the lower end of the second limit plate.

[0008] The fixed shaft is a hollow shaft, and the second limiting plate is cantilevered to the inner hollow part of the fixed shaft.

[0009] The mounting frame includes a base plate, a first support plate and a second support plate parallel to each other, the base plate is arranged vertically, the first support plate and the second support plate are vertically fixed on one side surface of the base plate, the driving mechanism is fixed on one side of the first support plate, the first linear guide and the second linear guide are fixed on the other side of the first support plate, the cam mechanism is arranged between the first support plate and the second support plate, the second connecting plate is U-shaped, one end of the second connecting plate is connected to the movable plate, the other end of the second connecting plate is connected to the first limiting plate, the second supporting plate is provided with a strip hole in the left and right directions, and when the movable plate moves, the side wall of the second connecting plate moves along the strip hole.

[0010] A plurality of strip-shaped box-shaped roller racks are embedded in the outer circumferential surface of the fixed shaft, and the length direction of the roller racks is along the axial length direction of the fixed shaft. All roller racks are arranged at intervals along the circumference of the fixed shaft, and a row of rollers are fixed in each roller rack. The rollers roll along the axial length direction of the fixed shaft. When loading or unloading materials, all rollers roll along the inner wall of the winding core.

[0011] A push plate is vertically fixed at one end of the movable plate adjacent to the fixed shaft, and the lower surface of the push plate is arc-shaped. When the push plate follows the movable plate to move above the fixed shaft, the push plate can push the winding core on the fixed shaft off to realize material unloading.

[0012] A plurality of positioning holes are provided on the upper surface of the overhanging end of the fixed shaft, and positioning columns are detachably inserted in the positioning holes. A stopper is fixed on the upper end of the positioning column. An arc-shaped shoulder is arranged at the other end of the fixed shaft, and the two ends of the winding core respectively abut against the shoulder and the stopper.

[0013] The moving block is fixed to the lower end of the second limiting plate through a buffer spring.

[0014] The multi-directional movable slide comprises an X-direction movable slide and a Z-direction movable slide. The X-direction movable slide comprises a mounting plate, a small hand wheel, a screw nut mechanism, two X-direction horizontal guide rails and two third sliders. The mounting frame is fixed to the two third sliders through a bottom plate. The third slider cooperates with the horizontal guide rail. The third slider is driven by the small hand wheel through the screw nut mechanism to realize X-direction movement. The horizontal guide rail and the screw nut mechanism are fixed on the mounting plate. The Z-direction movable slide comprises a vertical frame and a vertical chain transmission mechanism fixed on the vertical frame. The mounting plate is driven by the chain transmission mechanism to realize Z-direction movement. The moving direction of the movable plate is Y-direction. A movable wheel is arranged at the bottom of the vertical frame.

[0015] The beneficial effects of the present invention are as follows: when it is necessary to transport the winding core, the entire trolley is moved so that the fixed shaft is aligned with the winding core, and the driving mechanism drives the moving plate and the cam mechanism to move the moving block to the inside of the fixed shaft, and then the trolley is moved so that the fixed shaft is inserted into the winding core, and then the driving mechanism drives the moving plate and the cam mechanism to move the moving block to protrude beyond the outer circumferential surface of the fixed shaft. At this time, the moving block abuts against the inner wall of the winding core to achieve locking, so that the winding core is firmly sleeved on the fixed shaft. In this way, the winding core can be fixed during the transportation process, which effectively prevents the winding core from falling off, is safer to use, and only requires one person to operate the entire process, which is highly efficient, saves labor, and has high production efficiency.

DETAILED DESCRIPTION

[0022] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0023] like Figure 1-5 As shown, the rolled battery cell transport trolley of this embodiment includes a mounting frame 10, which is fixed on a multi-directional movable slide, and a movable plate 20 is arranged on the mounting frame 10. The movable plate 20 is driven by a driving mechanism to realize left and right bidirectional movement. A fixed shaft 30 is cantilevered outwardly on the mounting frame 10, and the axial length direction of the fixed shaft 30 is the same as the moving direction of the movable plate 20. A movable block 40 is embedded in the shaft body of the fixed shaft 30. When the movable plate 20 moves left and right, the movable block 40 is driven by a cam mechanism to move radially so that the movable block 40 is hidden inside the fixed shaft 30 or protrudes outside the outer peripheral surface of the fixed shaft 30. When loading, the fixed shaft 30 is inserted inside the core and the movable block 40 is against the inner wall of the core to achieve locking; when unloading, the movable block 40 is hidden inside the fixed shaft 30 and the movable plate 20 can push the core to separate from the fixed shaft 30. When the winding core needs to be transported, the entire trolley is moved so that the fixed shaft 30 is aligned with the winding core, and the driving mechanism drives the moving plate 20 and the cam mechanism to move the moving block 40 to the inside of the fixed shaft 30, and then the trolley is moved so that the fixed shaft 30 is inserted into the winding core, and the driving mechanism drives the moving plate 20 and the cam mechanism to make the moving block 40 protrude beyond the outer peripheral surface of the fixed shaft 30. At this time, the moving block 40 is against the inner wall of the winding core to achieve locking, so that the winding core is firmly sleeved on the fixed shaft 30, so that the winding core can be fixed during the transportation process, and the winding core can be effectively prevented from falling. It is safer to use, and the whole process only requires one person to operate, which is efficient, saves labor, and has high production efficiency.

[0024] The driving mechanism includes a large handwheel 51 and a synchronous belt 52 driven by the large handwheel 51. The movable plate 20 is arranged horizontally. One side of the movable plate 20 is connected to the synchronous belt 52 through a first connecting plate 53. The bidirectional rotation of the large handwheel 51 drives the bidirectional rotation of the synchronous belt 52 to realize the left and right bidirectional movement of the movable plate 20.

[0025] The mounting frame 10 is fixed with a first linear guide rail 15 in the left-right direction and a second linear guide rail 16 in the up-down direction. The cam mechanism includes a first limit plate 61 and a second limit plate 62. The plate surfaces of the first limit plate 61 and the second limit plate 62 are parallel. The first limit plate 61 forms a limit fit with the first linear guide rail 15 through a first slider. The second limit plate 62 forms a limit fit with the second linear guide rail 16 through a second slider. A limit column 63 is vertically fixed on the plate surface of one end of the second limit plate 62. A limiting hole 611 is opened, and the limiting hole 611 is a strip-shaped hole in the left-right direction and one end of the hole is bent downward. The movable plate 20 is connected to the first limiting plate 61 through the second connecting plate 70, and the limiting column 63 is inserted into the bent end inside the limiting hole 611. When the movable plate 20 drives the first limiting plate 61 to move left and right along the first linear guide rail 15, the first limiting plate 61 drives the second limiting plate 62 to move up and down along the second linear guide rail 16 through the limiting column 63, and the movable block 40 is fixed at the lower end of the second limiting plate 62.

[0026] The fixed shaft 30 is a hollow shaft, and the second limiting plate 62 is suspended to the inner hollow of the fixed shaft 30. The inner space of the fixed shaft 30 provides space for the second limiting plate 62 to move.

[0027] The mounting frame 10 includes a base plate 11, a first support plate 12 and a second support plate 13 which are parallel to each other. The base plate 11 is arranged vertically, and the first support plate 12 and the second support plate 13 are vertically fixed on one side of the base plate 11. The driving mechanism is fixed on one side of the first support plate 12, and the first linear guide rail 15 and the second linear guide rail 16 are fixed on the other side of the first support plate 12. The cam mechanism is arranged between the first support plate 12 and the second support plate 13. The second connecting plate 70 is U-shaped, and one end of the second connecting plate 70 is connected to the moving plate 20, and the other end of the second connecting plate 70 is connected to the first limiting plate 61. The second supporting plate 13 is provided with a strip hole 131 in the left and right directions. When the moving plate 20 moves, the side wall of the second connecting plate 70 moves along the strip hole 131. The setting of the strip hole 131 plays a role of avoidance, so that the first limiting plate 61 can move with the second connecting plate 70.

[0028] A plurality of strip-shaped box-shaped roller racks 81 are embedded in the outer circumference of the fixed shaft 30. The length direction of the roller racks 81 is along the axial length direction of the fixed shaft 30. All roller racks 81 are arranged at intervals along the circumference of the fixed shaft 30. A row of rollers 82 are fixed in each roller rack 81. The rollers 82 roll along the axial length direction of the fixed shaft 30. When loading or unloading, all rollers 82 roll along the inner wall of the winding core. The arrangement of the rollers 82 allows rolling friction between the winding core and the fixed shaft 30 during the cooperation process, thereby reducing wear.

[0029] A push plate 21 is vertically fixed to one end of the movable plate 20 adjacent to the fixed shaft 30. The lower surface of the push plate 21 is in an arc shape. When the push plate 21 moves above the fixed shaft 30 following the movable plate 20, the push plate 21 can push the winding core on the fixed shaft 30 off to realize unloading. The setting of the push plate 21 can realize automatic unloading.

[0030] A plurality of positioning holes are provided on the upper surface of the overhanging end of the fixed shaft 30, and positioning columns 91 are detachably inserted in the positioning holes. A stopper 92 is fixed on the upper end of the positioning column 91, and an arc-shaped shaft shoulder 93 is arranged at the other end of the fixed shaft 30. The two ends of the winding core are respectively against the shaft shoulder 93 and the stopper 92. Before loading, the stopper 92 is first removed, and after the winding core and the fixed shaft 30 are in place, the stopper 92 is installed, and the winding core is limited between the shaft shoulder 93 and the stopper 92, so that the stopper 92 can prevent the winding core from being separated from the fixed shaft 30, and ensure that the winding core is firmly fixed.

[0031] The moving block 40 is fixed to the lower end of the second limit plate 62 by a buffer spring 100. The buffer spring 100 provides a certain elasticity to the moving block 40, thereby preventing the second limit plate 62 from being damaged due to excessive pressure on the moving block 40 and the inner wall of the winding core caused by excessive displacement.

[0032] The multi-directional movable slide includes an X-direction movable slide and a Z-direction movable slide. The X-direction movable slide includes a mounting plate 111, a small hand wheel 112, a screw nut mechanism 113, two X-direction horizontal guide rails 114 and two third sliders 115. The mounting frame 10 is fixed on the two third sliders 115 through the bottom plate 11. The third slider 115 cooperates with the horizontal guide rail 114. The third slider 115 is driven by the small hand wheel 112 through the screw nut mechanism 113 to achieve X-direction movement. The horizontal guide rail 114 and the screw nut mechanism 113 are fixed on the mounting plate 111. The Z-direction movable slide includes a vertical frame 121 and a vertical chain transmission mechanism 122 fixed on the vertical frame 121. The mounting plate 111 is driven by the chain transmission mechanism 122 to achieve Z-direction movement. The moving direction of the movable plate 20 is the Y direction. A moving wheel 123 is arranged at the bottom of the vertical frame. The arrangement of the moving wheel 123 facilitates the movement of the entire trolley. In addition, the position of the fixed shaft 30 can be adjusted manually and quickly by means of the small hand wheel 112 .

[0033] The working process of the entire trolley is as follows: move the trolley to the core placement rack, control the multi-directional movable slide to align the fixed shaft 30 with the core, shake the large hand wheel 51 to hide the moving block 40 inside the fixed shaft 30, remove the stopper 92, move the trolley to directly insert the fixed shaft 30 into the core, shake the large hand wheel 51 in the opposite direction to make the moving block 40 rest against the inner wall of the core to achieve locking and fixing, install the stopper 92, and the loading is completed; move the trolley to the production equipment, move the core to the unloading position by controlling the multi-directional movable slide, remove the stopper 92, shake the large hand wheel 51, and the large hand wheel 51 with The dynamic synchronous belt 52 rotates, and the synchronous belt 52 drives the movable plate 20 and the first limit plate 61 to move toward the end where the fixed shaft 30 is located. Due to the limitation of the limit hole 611, the limit column 63 moves obliquely upward from the bent end of the limit hole 611 toward the other end, thereby forcing the second limit plate 62 to move upward. The second limit plate 62 drives the movable block 40 to move upward to hide inside the fixed shaft 30 to achieve unlocking. While the movable plate 20 moves, it drives the push plate 21 to move toward the overhanging end of the fixed shaft 30. While the push plate 21 moves, it pushes the winding core to gradually separate from the fixed shaft 30 to achieve material unloading.
