Description

Technical Field

[0001] The utility model relates to an assembly trolley, in particular to a vertical battery assembly trolley for a magnetic suspension mover. Background Art

[0002] At present, magnetic levitation technology has been widely used in battery production lines to transport workpieces for automated manufacturing of batteries. Specifically, the magnetic levitation assembly cart passes through various processing base stations along the battery production line in sequence, and can gradually complete the production processes such as loading, assembling and welding of various battery components.

[0027] A vertical battery assembly vehicle for a magnetic suspension mover, such as Figure 1~Figure 5 As shown, it relates to a mechanical trolley that can be used for battery transportation and manufacturing using magnetic levitation technology. Its structure is mainly composed of a base 1 installed on a magnetic levitation mover 1, a bottom plate assembly 2 that is lifted and set on the base, and a clamp seat 3 fixed on the bottom plate assembly.

[0028] The base plate assembly 2 includes a base plate 21 and two pairs of bottom wheels 23 respectively arranged on both sides of the bottom surface of the base plate, each bottom wheel is installed on a bottom wheel seat 22, and then fixed to the bottom surface of the base plate 21 through the bottom wheel seat, and the base plate is then installed on the base 11 for lifting and movement through a plurality of linear bearings 24; in this way, when the assembly trolley enters the processing base station, the two pairs of bottom wheels 23 can be used to roll along the conveying track in the processing base station, and then the base plate 21 and other components on the base plate can be slid upward and supported through the linear bearings 24, so that the magnetic suspension mover 1 will not be subjected to force when assembling the battery workpiece, and the entire assembly trolley can be supported by the force of the two pairs of bottom wheels 23, and it can also form adaptive lifting and movement with the height fluctuation of the conveying track.

[0029] The fixture seat 3 is in the shape of "[". Figure 1 As shown, the right bottom of the "["-shaped clamp seat 3 is provided with a lower positioning notch 31, and the right top of the "["-shaped clamp seat 3 is provided with an upper positioning notch 32. When the robot conveys the vertical battery 6, the bottom side of the vertical battery can be matched and fitted in the lower positioning notch 31 to form a lower positioning, and the top side of the vertical battery 6 can be matched and fitted in the upper positioning notch 32 to form an upper positioning; and, the middle part of the "["-shaped clamp seat 3 is also provided with a clamping claw assembly 4 for clamping or releasing the middle part of the vertical battery, so as to ensure that the vertical battery 6 is firmly positioned or conveniently removed after manufacturing.

[0030] The clamping jaw assembly 4 includes two clamping rods 41 respectively arranged on both sides of the clamping base 3. Figure 1On the front and rear sides of the "["-shaped clamp seat shown in the figure, the middle part of each clamp rod 41 is hinged and rotated with the clamp seat 3 through a vertically arranged pin shaft, so that the front and rear ends of each clamp rod 41 can form a seesaw-like movement in a horizontal plane around the hinged middle part; the rear end of each clamp rod 41 is provided with a roller 43, and the rollers 43 at the rear ends of the two clamp rods 41 respectively roll and contact on the two side surfaces of a vertically installed top opening rod 7, and a tension spring 42 connected to each other is also provided between the rear ends of the two clamp rods 41.

[0031] The two sides of the top opening rod 7 are respectively provided with Figure 6 As shown in the elevation surface 71, the push-open rod 7 can be driven by an external mechanism to move up and down, and when the push-open rod 7 moves up and down, the rollers 43 at the rear ends of the two clamping rods 41 can roll and contact the elevation surface 71, thereby driving the front ends of the two clamping rods 41 to move closer to each other to clamp the middle of the vertical battery 6 or move away from each other to release the middle of the vertical battery 6. Specifically: when the rollers 43 at the rear ends of the two clamping rods 41 roll and contact the high surface 711 of the elevation surface 71, the rear ends of the two clamping rods 41 will be driven to move away from each other, thereby driving the front ends of the two clamping rods 41 to move closer to each other to clamp the middle of the vertical battery 6; when the rollers 43 at the rear ends of the two clamping rods 41 roll and contact the low surface 712 of the elevation surface 71, the tension spring 42 will elastically pull the rear ends of the two clamping rods 41 closer to each other, thereby driving the front ends of the two clamping rods 41 to move away from each other to automatically release the middle of the vertical battery 6.

[0032] The top and bottom of the fixture seat, that is, Figure 1 The top and bottom of the left side of the “[”-shaped clamp seat 3 are respectively provided with guide sliders 8, which can be used to guide the lifting and lowering movement of the ejection rod 7 and ensure the stability of the lifting and lowering movement.

[0033] The opposite surfaces of the front ends of the two clamping rods 41 are respectively provided with clamping blocks 44 made of flexible material, and the clamping blocks contact the middle of the vertical battery 6 to form a flexible clamp, thereby preventing the outer surface of the clamped vertical battery 6 from being deformed due to the clamping force, and at the same time, when the vertical battery 6 is pushed upward under the action of the external mechanism, it can also have a certain upward movement stroke.

[0034] The top of the clamp seat 3 is provided with a positioning assembly 5, which includes a fixed plate 51 fixed to the top of the clamp seat 3, guide rods 52 arranged on both sides of the fixed plate, and a movable plate 53 arranged between the two guide rods. The movable plate can be guided by the two guide rods 52 to slide back and forth horizontally relative to the fixed plate 51, and form a mutual closing and locking or mutual separation and opening between the fixed plate. The specific structure is as follows: a plurality of buckle rods 54 are provided on the fixed plate 51. In this embodiment, two buckle rods are provided, and the middle part of each buckle rod 54 is rotatably mounted on the fixed plate 51, so that the front end and the rear end of each buckle rod 54 can surround the middle part. The rear end of each buckle rod 54 is elastically pushed upward by an elastic element 55, and the elastic element 55 can be a small cylindrical spring as shown in the present embodiment, so as to drive the hook 541 at the front end of each buckle rod 54 to be pressed down, and a buckle hole 531 corresponding to the front end of each buckle rod 54 is provided on the movable plate 53; in this way, when the movable plate 53 is guided by the two guide rods 52 to slide and close relative to the fixed plate 51, the hook 541 at the front end of each buckle rod 54 is pressed down and buckled in the corresponding buckle hole 531 to form a lock, so that the movable plate 53 will not be detached from the fixed plate 51.

[0035] The fixed plate 51 and the movable plate 53 are both provided with a half groove 59. Figure 7 As shown in the figure, the top and bottom surfaces of the fixed plate 51 and the movable plate 53 are both provided with a half groove 59, and the shape of the half groove is usually consistent with the shape of the vertical battery 6. If the vertical battery in this embodiment is a cylindrical battery, the corresponding half groove 59 is a semicircular groove; wherein, when the fixed plate 51 and the movable plate 53 are closed and locked with each other, the two semicircular grooves are just engaged with each other to form a complete circular positioning groove, that is, the top surfaces of the fixed plate 51 and the movable plate 53 can form a circular top positioning groove 57 when they are engaged, and the fixed plate 51 When the bottom surface of the movable plate 53 is buckled, a circular bottom positioning groove 58 can be formed. The purpose of this design is that the clamped vertical battery 6 can be pushed upward to a certain upward movement under the action of the external mechanism, and the top of the vertical battery 6 can be exactly fitted in the bottom positioning groove 58, while the top positioning groove 57 can position and clamp the current collecting plate 9, and the current collecting plate is exactly centered on the top of the vertical battery 6, thereby facilitating the perfect completion of the subsequent welding process and effectively ensuring the reliability of the battery performance.

[0036] Of course, the positioning and clamping structure of the current collecting plate 9 in the top positioning groove 57 can be as shown in the embodiment. Figure 8 , Fig. 9 As shown, a positioning protrusion 571 is provided on the inner wall of the half groove 59 constituting the top positioning groove 57 , and the positioning protrusion 571 can be just fitted into the preset groove on the outer circumference of the collecting plate 9 to form a clamping positioning, thereby preventing the collecting plate 9 from being displaced in the top positioning groove 57 .

[0037] In addition, a disengagement spring 56 is provided between the fixed plate 51 and the movable plate 53. Once the hook 541 at the front end of each buckle rod 54 is disengaged from the buckle hole 531, the disengagement spring 56 can elastically push the movable plate 53 away from the fixed plate 51 automatically, which facilitates the automatic opening of the movable plate 53 relative to the fixed plate 51.

[0038] The working process of the utility model is as follows:

[0039] 1. The vertical battery 6 is grasped by the robot and transported to the assembly vehicle, and the bottom side of the vertical battery 6 is positioned in the lower positioning notch 31 at the bottom of the clamp seat 3, and the top side of the vertical battery 6 is positioned in the upper positioning notch 32 at the top of the clamp seat 3, and the middle part of the vertical battery 6 is clamped by the clamping claw assembly 4;

[0040] 2. The movable plate 53 of the positioning assembly 5 moves horizontally relative to the fixed plate 51 and closes and locks with each other to form a top positioning groove 57 and a bottom positioning groove 58;

[0041] 3. The external mechanism pushes the clamped vertical battery 6 upward and moves a certain distance, so that the top of the vertical battery 6 is positioned in the bottom positioning groove 58;

[0042] 4. Position and clamp the current collecting plate 9 in the top positioning groove 57. At this time, the current collecting plate 9 is exactly centered on the top of the vertical battery 6;

[0043] 5. The assembly trolley is driven into the welding station by the magnetic suspension mover 1. After the current collecting plate 9 is pressed by the external pressure head, the current collecting plate 9 and the outer circumference of the top of the vertical battery 6 can be welded in a circular manner.

[0044] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
