Description

Battery pack transfer device and turnover mechanism thereof

Technical Field

The utility model relates to a battery processing technology field, in particular to battery package transfer device and tilting mechanism thereof.

Background

During the manufacturing process of the battery pack, the related components are assembled to the battery pack by manual work. The battery pack is generally horizontally placed on the carrier, and the carrier drives the battery pack to circulate among different stations. Because the battery package length and width size is great, if the battery package is horizontal to be placed, be inconvenient for the manual work to operate the middle zone of battery package. Therefore, before manual operation, the carrier carrying the battery pack needs to be turned over by a certain angle by using the turning mechanism.

The existing turnover mechanism generally drives the carrier to rotate around the central axis, so that the battery pack is driven to be turned over. However, after the battery pack is turned over by the turning-over method, the middle areas of the carrier and the battery pack are still positioned in the middle of the turning-over mechanism. In general, since the turnover mechanism has a large size, the distance from the edge to the center is long. This would result in a very inconvenient manual operation for the middle area of the battery pack.

Referring to fig. 1 and 2, the present invention provides a battery pack transferring device 10 and a turnover mechanism 100. The battery pack transfer device 10 includes a turnover mechanism 100 and a transfer cart 200.

Turnover mechanism 100 is located on transfer cart 200. The carrier 30 carrying the battery pack 20 may be mounted on the turnover mechanism 100 by means of snap-fitting, screw fastening, or the like. The transfer trolley 200 can drive the turnover mechanism 100 and the carriers 30 thereon to circulate among various stations. The transfer cart 200 is typically an agv (automated Guided vehicle) cart, which is typically equipped with an electromagnetic or optical automated navigation device capable of traveling along a prescribed navigation path.

Referring to fig. 3 and 4, the tilting mechanism 100 according to the preferred embodiment of the present invention includes a support base 110, an adaptor 120, a rotation support assembly 130 and a driving member 140.

Support base 110 serves as a support and is used to secure canting mechanism 100 to transfer cart 200. The support 110 is generally a metal frame structure, and is usually provided with a reinforcing rib plate, so that it has high rigidity and supporting strength. The adaptor 120 may be plate-shaped, strip-shaped or block-shaped and is used for fixedly connecting the carrier 30. Specifically, in the present embodiment, the adaptor 120 is a tray for conveniently carrying and installing the carrier 30. The support base 110 is coupled to the adapter 120 by rotating the support assembly 130 to enable the adapter 120 to be flipped relative to the support base 110. Therefore, under the combined action of the rotary support assembly 130 and the driving member 140, the adaptor 120 can rotate relative to the support 110, so as to drive the carrier 20 and the battery pack 30 thereon to turn.

Further, the rotation support assembly 130 includes a first support rod 131 and a second support rod 132. The two ends of the first supporting rod 131 are respectively rotatably disposed on the support 110 and the adaptor 120. Similarly, the second rod 132 is rotatably disposed at two ends of the support 110 and the adaptor 120, respectively. Also, the first struts 131 intersect the second struts 132.

Specifically, the support 110 is provided with a first hinge position and a third hinge position which are spaced apart from each other, and the adaptor 120 is provided with a second hinge position and a fourth hinge position which are spaced apart from each other. The two ends of the first supporting rod 131 are respectively and rotatably disposed at the first hinge position and the second hinge position, and the two ends of the second supporting rod 132 are respectively and rotatably disposed at the third hinge position and the fourth hinge position.

The first support rod 131 and the second support rod 132 may have the same structure, and both may have a long-strip-shaped metal rod-like structure. The first support rod 131 and the second support rod 132 can be rotatably mounted with the support 110 and the adaptor 120 by means of a pin, a hinge, a rotating shaft, and the like. Furthermore, the rotation axes of the first and

second struts

131 and 132 extend in the same direction, for example, in a direction perpendicular to the plane of the drawing as shown in fig. 3.

Continuing with the example of FIG. 3, the first hinge location is located at the left end of the support base 110, and the third hinge location is located at the right end of the support base 110; the second hinge location is located at the right end of the adaptor 120 and the fourth hinge location is located at the left end of the adaptor 130. Thus, the first strut 131 and the second strut 132 can be crossed.

It should be noted that the terms "first" and "second" are merely used to distinguish between the different positions of the struts, and the positions of the first strut 131 and the second strut 132 may be reversed.

Specifically, in this embodiment, the first hinge joint and the third hinge joint are both provided with a rotary support seat 111, and correspondingly, the second hinge joint and the fourth hinge joint are both provided with a rotary mounting seat 121. Thus, the first and

second struts

131 and 132 can be more conveniently installed and can better support the first and

second struts

131 and 132.

The driving member 140 can drive the first rod 131 and the second rod 132 to rotate relative to the support 110. The driving member 140 may be a motor, a cylinder or an electric cylinder, and may perform a linear motion or a circular motion. The driving member 140 can be in transmission connection with at least one of the first and

second struts

131, 132, so as to realize driving. Under the driving of the driving member 140, the first rod 131 and the second rod 132 can rotate clockwise or counterclockwise, so as to drive the adaptor 120 to turn in different directions.

Referring to fig. 3 and 5, when the driving member 140 drives the first supporting rod 131 and the second supporting rod 132 to rotate counterclockwise, one end (right end) of the adaptor 120 having the second hinge position is raised, and one end (left end) of the adaptor 120 having the fourth hinge position is lowered. At this time, the adaptor 120 is turned to the left side, so that the carrier 30 on the adaptor 120 and the battery pack 20 thereon can be turned to the left side.

Referring to fig. 3 and 6, when the driving member 140 drives the first supporting rod 131 and the second supporting rod 132 to rotate clockwise, one end (right end) of the adaptor 120 with the second hinge position descends, and one end (left end) of the adaptor 120 with the fourth hinge position ascends. At this time, the adaptor 120 is turned over to the right, so that the carrier 30 on the adaptor 120 and the battery pack 20 thereon can be turned over to the right.

It can be seen that, in the process of turning over the battery pack 20, both the second hinge joint and the fourth hinge joint of the adaptor 120 can be used as the pivot for the adaptor 120 to rotate. Moreover, the first strut 131 and the second strut 132 can rotate relative to the support 110, so that the height of the pivot point of the adaptor 120 is changed in real time. In this way, the middle area of the carrier 30 can be continuously turned outwards during rotation, and the height can be maintained approximately unchanged, thereby facilitating manual operation of the middle area of the battery pack 20.

Moreover, the battery pack 20 can be driven to turn right or left by the turnover mechanism 100. Therefore, the efficiency of assembling the battery pack 20 can also be improved. As shown in fig. 2, two stations, a first station 01 and a second station 02 are disposed opposite to each other, and the transfer cart 200 can drive the turnover mechanism 100 to move between the first station 01 and the second station 02. The turnover mechanism 100 can drive the carrier 30 and the battery pack 20 thereon to turn to the left, so that a worker or a manipulator at the first station 01 can complete the related operations on the battery pack 20; then, the turnover mechanism 100 drives the carrier 30 and the battery pack 20 thereon to turn to the right, so that the worker or the robot at the second station 02 can complete the operation related to the battery pack 20.

In this embodiment, the first hinge position and the third hinge position have the same distance from the center of the support 110, the second hinge position and the fourth hinge position have the same distance from the center of the adaptor 120, and the first strut 131 and the second strut 132 have the same length.

That is, the support 110, the adaptor 120 and the rotation support assembly 130 may form a symmetrical structure therebetween. Thus, the turning angles of the left and right sides of the adaptor 120 can be the same.

Referring to fig. 4 again, in the present embodiment, there are two first struts 131, two first struts 131 are disposed at intervals along the extending direction of the rotation axis of the first struts 131, two second struts 132 are disposed at intervals along the extending direction of the rotation axis of the second struts 132, and the two second struts 132 are disposed at intervals along the extending direction of the rotation axis of the second struts 132.

The first strut 131 and the second strut 131 have the same rotational axis extending in the same direction, and both are in the horizontal direction as shown in fig. 4. That is, the two first struts 131 are respectively installed at two opposite sides of the bracket 110 in the horizontal direction. Similarly, two second struts 132 are respectively installed at two opposite sides of the support 110 in the horizontal direction. Correspondingly, the first hinge joint, the second hinge joint, the third hinge joint and the fourth hinge joint are also respectively provided with two hinge joints. Thus, two supporting points exist between the adaptor 120 and the support 110, so that the supporting connection is stable, and the stability of the overturning process is improved.

It should be noted that, in other embodiments, only one set of the first strut 131 and the second strut 132 may be provided, and the first hinge position, the second hinge position, the third hinge position and the fourth hinge position are provided in the middle of the support base 110 and the adaptor 120, so as to form a relatively stable support.

Further, in this embodiment, the rotation support assembly 130 further includes a connecting rod 133, the two first supporting rods 131 are located between the two second supporting rods 132, and two ends of the connecting rod 133 are respectively fixed to the two first supporting rods 131.

Two first struts 131 are located on the inside and two second struts 132 are located on the outside. Thus, the first rod 131 and the second rod 132 are ensured not to interfere with each other during rotation. The links 133 may be a metal rod-like structure, and the number thereof may be one or more than two. The provision of the connecting rod 133 stabilizes the connection between the two first supporting rods 131, thereby further increasing the supporting strength of the rotary support assembly 130, and thus making the supporting connection between the support 110 and the adaptor 120 more stable.

Furthermore, in the present embodiment, the driving member 140 has a housing and a telescopic end, the housing of the driving member 140 is rotatably disposed on the support 110, and the telescopic end of the driving member 140 is rotatably disposed on the connecting rod 133.

The axis of rotation of the driving member 140 also coincides with the direction in which the axes of rotation of the first and

second struts

131, 132 extend. Therefore, the driving member 140 can rotate synchronously with the first and

second struts

131 and 132. The driving member 140 may be a cylinder or an electric cylinder, and the telescopic end thereof is a piston rod. The driving member 140 can drive the first rod 131 and the second rod 132 to rotate by extending and contracting the telescopic end.

As shown in fig. 5 and 6, when the telescopic end of the driving member 140 extends, the first rod 131 and the second rod 132 are driven to rotate counterclockwise; when the retractable end of the driving member 140 retracts, the first rod 131 and the second rod 132 are driven to rotate clockwise.

The driving member 140 is provided without an additional transmission mechanism, so that the turnover mechanism 100 has a simple and compact structure. Moreover, the telescopic end of the driving member 140 acts on the middle portion of the connecting rod 133, so that the acting force for the rotating support 130 is relatively balanced.

Referring to fig. 5 and fig. 6 again, in the embodiment, the turnover mechanism 100 further includes an elastic buffer 150 disposed on the support 110, and the first support rod 131 and the second support rod 132 can rotate to abut against the elastic buffer 150 when rotating toward the support 110.

The elastic buffer 150 may be a block-shaped or column-shaped structure formed by elastic materials such as rubber, sponge, and silica gel. Since the first strut 131 and the second strut 132 can rotate to abut against the elastic buffer 150, the first strut 131 and the second strut 132 can be prevented from directly colliding with the support 110 to cause damage. More importantly, the elastic buffer 150 can absorb energy generated by collision, so as to prevent the carrier 30 and the battery pack 20 from falling off due to vibration.

Meanwhile, the elastic buffer 150 may also play a role in limiting, so as to control the rotation angles of the first support rod 131 and the second support rod 132, and finally control the turning angles of the connecting element 120 and the carrier 30.

Further, in the present embodiment, the elastic buffer 150 includes a mounting pillar 151 fixed to the support 110 and an elastic ball 152 disposed at a distal end of the mounting pillar 151.

The mounting post 151 may be a metal or plastic post that is threadably fastened or welded to the support base 110. The elastic ball 152 may be made of rubber, sponge, silica gel, or other elastic material to provide a buffering function. Moreover, the surface of the resilient bulb 152 is spherical. Therefore, when contacting with the first strut 131 or the second strut 132, the contact area is larger, thereby contributing to the improvement of the cushioning effect.

Specifically, in this embodiment, there are two elastic buffers 150, one of the elastic buffers 150 is disposed on one side of the first hinge position facing the third hinge position and can abut against the second supporting rod 132, and the other elastic buffer 150 is disposed on one side of the third hinge position facing the first hinge position and can abut against the first supporting rod 131.

Taking fig. 3 as an example, the two elastic buffers 150 are respectively disposed at the left end and the right end of the support 110. When the first strut 131 and the second strut 132 rotate clockwise, the first strut 131 can abut against the right elastic buffer 150 to realize limiting; when the first support rod 131 and the second support rod 132 rotate counterclockwise, the second support rod 132 can abut against the right elastic buffer 150 to realize the limit. Thus, the first strut 131 and the second strut 132 can be limited by different elastic buffers 150, so that the counterclockwise and clockwise rotation angles can be different, thereby being capable of turning different angles in different directions.

Further, in the present embodiment, the position of each elastic buffer 150 on the support 110 is adjustable in the direction from the first hinge position to the third hinge position.

The elastic buffer 150 may be mounted to the bracket 110 by screw fastening or a way of matching a guide rail with a slider. Wherein the direction from the first hinge to the third hinge is the horizontal direction shown in fig. 3. By adjusting the position of the elastic buffer 150, the rotation angle of the first support rod 131 and the second support rod 132 can be adjusted, so that the turning angle of the carrier 30 and the battery pack 20 can be finally adjusted.

Specifically, after the right elastic buffer 150 moves leftward, the clockwise rotation angle of the first support rod 131 and the second support rod 132 decreases, and the corresponding turning angle decreases, or vice versa; when the left-end elastic buffer 150 moves to the right, the counterclockwise rotation angle of the first and

second struts

131 and 132 decreases, and the corresponding flip angle decreases, or vice versa.

In the turnover mechanism 100, the adaptor 120 can be used to fixedly connect to the carrier 30 carrying the battery pack 20, and the adaptor 120 can rotate relative to the support 110 under the action of the rotary support assembly 130 and the driving member 140, so as to drive the carrier 30 to turn over. In the process of turning over, the first support rod 131, the second support rod 132 and the second hinge position and the fourth hinge position of the adaptor 120 can both be used as the pivot of the adaptor 120, and the first support rod 131 and the second support rod 132 can both rotate relative to the support 110, so that the height of the pivot of the adaptor 120 is also changed in real time. In this way, the middle area of the carrier 30 can be continuously turned outwards during rotation, and the height can be maintained approximately unchanged, thereby facilitating manual operation of the middle area of the battery pack 20.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
