Description

Technical Field

[0001] The invention relates to a material shifting device. Background Art

[0002] With the development of electronic technology and the popularization of electronic devices, the demand for batteries in electronic products such as tablets, computers and mobile phones has also grown explosively.

[0003] Cell welding is an important process in the battery assembly process, which requires welding metal components such as terminals and connecting plates to the positive and negative electrodes of the cell. In order to improve the degree of automation, an automatic material feeding device is usually used to feed in and clamp the jig where the battery to be worked is placed, and the welding is carried out by an automatic welding machine.

[0004] In the prior art, in order to realize the in and out movement of the jig, two-stage cylinder control is usually required. That is, the jig is clamped by the action of the claw on the swing cylinder, and after the operation is completed, the ejection cylinder is activated to eject the jig. However, due to the need to use two-stage cylinder control, the structure of the material-moving device is complex, the action is cumbersome, the cost is high and the efficiency is low.

[0005] Therefore, in view of the above-mentioned technical problems in the prior art, there is an urgent need for a material shifting device that can simultaneously realize shifting in and shifting out through a set of cylinders and simultaneously ensure processing accuracy and yield rate. Summary of the invention

[0006] The inventor of the present invention has conducted intensive research and proposed a material shifting device, the technical solution of which is described as follows.

[0007] The present invention provides a material-push device, characterized in that it comprises: a frame having a base for placing a jig, a back plate erected from the base and side plates on both sides; a driving mechanism, respectively arranged on both sides of the frame; and a pusher claw, respectively fixed to the driving mechanism on both sides, wherein the two pushers claws each have a first arm portion and a second arm portion, and the jig is pushed into the frame by the first arm portion when the pusher claw rotates in a first direction driven by the driving mechanism, and the jig is pushed out of the frame by the second arm portion when the pusher claw rotates in a second direction opposite to the first direction driven by the driving mechanism.

[0008] Thus, by having the first arm portion and the second arm portion, the finger can be simultaneously dialed in and dialed out by a set of cylinders.

[0009] In addition, preferably, in the material pushing device, the first arm portion is in a straight arm shape, and when the pusher claw rotates in the first direction, the side portion of the first arm portion pushes the jig into the frame, and the second arm portion is in a curved shape, and when the pusher claw rotates in the second direction, the end portion of the second arm portion pushes the jig out of the frame.

[0010] Thus, by using the side surface of the first arm to push the jig in, the jig can be pushed in smoothly, and by using the end of the second arm to push the jig out, the jig can be surely pushed out.

[0011] In addition, preferably, in the material-moving device, the two driving mechanisms are respectively swing cylinders, and the swing cylinders limit the rotational stroke of the pusher claw between a first position and a second position.

[0012] Thus, the rotation and limiting of the pusher claw are realized conveniently.

[0013] Furthermore, preferably, in the material shifting device, when the shifting claw rotates in the first direction to the first position, the jig is abutted against the back plate of the frame.

[0014] Therefore, the jig is clamped by the back plate and the claws to ensure the accuracy of welding.

[0015] Furthermore, preferably, in the material shifting device, the side plate has an inclined portion at the same height as the shifting claw, and when the shifting claw rotates to the first position in the first direction, the side surface of the first arm abuts against the inclined portion in a manner flush with the inclined portion.

[0016] Therefore, the abutment force between the pusher claw and the jig is buffered by the inclined surface of the side plate, thereby ensuring the accuracy of welding and avoiding damage to the jig.

[0017] Furthermore, preferably, in the material shifting device, the back plate of the frame has a through hole at the same height as the shifting claw, and the through hole prevents the second arm from interfering with the back plate when rotating between the first position and the second position.

[0018] Therefore, by providing the through hole on the back plate, the fixture can be easily removed.

[0019] In addition, preferably, in the material pushing device, when the pusher claw is located at the second position, if the jig is fed to the end portion contacting the second arm portion, the first arm portion does not interfere with the feeding process, and during the rotation of the pusher claw in the first direction, the side portion of the first arm portion can push the jig into the frame.

[0020] Thus, by making the jig contact the end of the second arm portion during feeding, it is easy to place the jig in a position where dialing can be performed.

[0021] In addition, preferably, in the material shifting device, the jig is a battery jig for placing at least one battery to be worked on, and has a through hole for exposing the battery to be worked on from above, and the material shifting device also has a cover body fixed between the side plates on both sides of the frame, and the cover body has at least one through hole for welding, and when the shifting claw rotates in the first direction to the first position, the through hole of the battery jig is aligned with the through hole of the cover body, so that the welding device can weld the battery to be worked on through the through hole.

[0022] Therefore, the material-dispensing device can effectively implement the dispensing and dispensing during the welding of the battery cells. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Hereinafter, the embodiments of the present invention will be described using the accompanying drawings. However, in the embodiments described below, various technically preferred limitations are added for the implementation of the present invention. Therefore, the scope of the technology disclosed herein is not limited to the following embodiments and illustrated examples. Furthermore, the sizes, shapes, and proportional relationships in the illustrated examples are only for illustration, and are not specific sizes, shapes, and proportional relationships. In addition, in the accompanying drawings, the same symbols are used for the common structures in the embodiments, and repeated descriptions are omitted, and for the same structure, the illustration of the figure mark is sometimes omitted.

[0028] Figure 1 FIG. 1 is a perspective view schematically showing a material-dispensing device 100 according to an embodiment of the present invention. Figure 1 As shown, the material shifting device 100 is used for shifting in and out of the battery fixture 200, and comprises a frame 110, a cylinder 120, a shifting claw 130, a cover 140 and a substrate 150. The frame 110 is fixed on the substrate 150, and can be a separate structure from the substrate 150, or can be integrally formed with the substrate 150. On the left and right sides of the frame 110, a pair of cylinders 120 and a pair of shifting claws 130 are symmetrically arranged with the center line of the front-to-back direction of the frame 110 as the symmetry axis.

[0029] Figure 2 FIG. 1 is an exploded view schematically showing a material-dispensing device 100 according to an embodiment of the present invention. Figure 2 , describing the detailed structure of each component of the material diverting device 100.

[0030] The frame 110 has a base 111, side panels 112 on both sides, a back panel 113 and cylinder seats 114 on both sides. The frame 110 can be assembled by assembling the above components separately or in one piece. The base 111 has a plane for placing the battery fixture 200. At the beginning of the operation, the battery fixture 200 is placed at the target position on the base 111 by a clamping and feeding device (not shown) such as a manipulator or a conveyor roller. The plane on the base 111 for placing the battery fixture 200 can be flush with the horizontal plane or slightly tilted downward toward the inner side (operation side) of the frame.

[0031] The side plates 112 on both sides stand up from both sides of the base 111, and the width between the side plates 112 on both sides matches the width of the battery fixture 200, and functions as a limiting mechanism for limiting the movement of the battery fixture 200 placed on the base 111. Secondly, in the side plates 112 on both sides, at the same height as the first arm portion 131 of the finger 130 described later, there are inclined portions 1120, and the specific functions of the inclined portions 1120 will be described later. In addition, in the side plates 112 on both sides, there are clamping portions 1121 for clamping the cover body 140 on the upper side.

[0032] The back plate 113 stands upright from the rear end of the base 111, and functions as a mechanism for clamping the battery jig 200 by the abutment force from the first arm portion 131 of the pusher claw 130 described later. On both sides of the back plate 113, at the same height as the second arm portion 132 of the pusher claw 130 described later, there are through holes 1130 that allow the second arm portion 132 to pass through without interference when rotating.

[0033] The cylinder seats 114 on both sides are arranged outside the side plates 112 on both sides, and are used to place the cylinders 120 and the pusher claws 130 , and have a height matching the height of the base 111 .

[0034] A pair of cylinders 120 are placed on the cylinder seats 114 on both sides, respectively, to drive the pusher claws 130 fixed to the cylinders 120 to rotate. The cylinder 120 is, for example, a swing cylinder, and includes a cylinder body 121 and a swing arm 122. A piston is provided in the cylinder body 121, and the piston is pushed to reciprocate by the compressed gas supplied into the cylinder body 121, thereby driving the swing arm 122 to rotate within a certain range. The structure of the cylinder 120 is not limited, and for example, it can be a gear rack swing cylinder or a vane swing cylinder.

[0035] In addition, the cylinder 120 limits the rotational travel of the pusher 130 between the first position and the second position by limiting the rotational angle of the swing arm 122. The rotational angle of the swing arm 122 can be limited by the stroke of the piston, or a mechanical or electromagnetic limiting mechanism can be set in the cylinder body 121.

[0036] A pair of pusher fingers 130 are fixed to the swing arms 122 of the cylinder 120 on both sides. For example, the pusher fingers 130 are fixed to the swing arms 122 of the cylinder 120 by inner locking bolts. The pusher fingers 130 include a first arm portion 131 and a second arm portion 132. The first arm portion 131 is in a straight arm shape extending toward the frame 110 side, and the second arm portion 132 is in a substantially U-shaped curved shape, with its end portion generally facing the front side of the frame 110. Under the drive of the cylinder 120, the pusher fingers 130 can rotate from a standby position (an example of the second position) toward the back plate 113 side (an example of the first direction) to an operating position (an example of the first position) for performing welding. After the welding operation is completed, the pusher fingers 130 can rotate from the operating position to the opposite direction of the back plate 113, that is, the outside of the base 111 (an example of the second direction) to the standby position.

[0037] The cover 140 is mounted between the clamping parts 1120 of the side plates 112 on both sides, and functions as a welding shield, for example. When performing welding operations, the battery fixture 200 is covered by the cover 140 to protect the safety of the operator. The cover 140 is provided with a through hole, through which the welding device passes to perform welding operations on the battery to be operated in the battery fixture 200.

[0038] The battery fixture 200 is provided with a plurality of through holes for accommodating the batteries to be operated, and the plurality of batteries to be operated are installed and fixed through the through holes. In addition, the plurality of batteries to be operated can also be removed from the side of the battery fixture 200 through a quick release mechanism, for example.

[0039] Below, refer to Figure 3B , Figure 3A An operation example of the finger 130 performing insertion and removal of the battery jig 200 will be specifically described.

[0040] Figure 3A FIG. 1 is a top view schematically showing a pusher finger 130 in a second position according to an embodiment of the present invention. Figure 3B The top view schematically shows a pusher claw 130 in a first position according to an embodiment of the present invention. First, the positions of the swing arms 122 of the cylinders 120 on both sides are adjusted so that the swing arms 122 are located at the end closest to the outside of the base 111, so that the pusher claw 130 fixed on the cylinder 120 is in the first position. Figure 3A The standby position (second position) is shown.

[0041] Afterwards, when the finger 130 is in Figure 3A When the battery jig 200 is in the standby position shown in the figure, the battery jig 200 is placed at the target position on the base 111. The target position is, for example, a position in contact with the end of the second arm 132 of the pusher claw 130. The size of the straight arm 131 is set so that the first arm 131 does not interfere with the feeding process during the process of feeding the battery jig 200 to the target position. In addition, the size of the straight arm 131 and the U-shaped curved second arm 132 are set so that when the battery jig 200 is placed at a position in contact with the end of the second arm 132 on the base 111, during the process of the pusher claw 130 rotating toward the back plate 113 side, the side surface of the first arm 131 can abut against the battery jig 200 and push the battery jig 200 into the interior of the frame 110 (i.e., into the back plate 113 side). Therefore, the battery jig 200 can be placed at a position where dialing can be performed simply by placing the battery jig 200 at the end that contacts the second arm portion 132 during feeding.

[0042] After that, the air cylinder 120 is started, and driven by the swing arm 122 of the air cylinder 120, the pusher finger 130 rotates from the standby position toward the back plate 113 side. Figure 3A The finger 130 on the left side rotates counterclockwise, and Figure 3A The pusher claw 130 on the right side rotates clockwise. During this rotation, the side surface of the first arm 131 first contacts and abuts against the battery jig 200, and the battery jig 200 moves toward the back plate 113 side under the push of the side surface of the first arm 131. By setting the first arm 131 in a straight arm shape, the side surface of the first arm 131 can smoothly push the battery jig 200 into the jig, and the tilting of the battery jig 200 caused by the position deviation of the pusher claws 130 on both sides can be avoided. In addition, during this rotation, the second arm 132 passes through the through hole 1130 in the back plate 113 and is moved out of the frame 110. During this process, there is no interference between the second arm 132 and the back plate 113.

[0043] The finger 130 rotates from the standby position toward the back plate 113 until Figure 3B The battery jig 200 shown in the figure is in the working position (first position) where it abuts against the back plate 113. That is, under the action of the force from the side surface of the first arm 131, the battery jig 200 abuts against the back plate 113, so that the battery jig 200 is clamped by the claw 130. Figure 3BIn the state shown, the side surface of the first arm portion 131 abuts against the inclined surface portion 1120 of the side plates 112 on both sides in a manner that is flush with the inclined surface portion 1120, so that part of the rotational torque from the first arm portion 131 is absorbed by the inclined surface portion 1120, and while the battery fixture 200 can be clamped by the first arm portion 131, damage to the claw 130 and the battery fixture 200 is avoided.

[0044] Afterwards, a welding device (not shown) performs welding operations on the battery to be operated in the battery fixture 200 through the through hole on the cover 140. The welding device is, for example, a laser welding device, which can perform welding operations automatically under the control of a robot arm or by an operator. The welding operation is, for example, the operation of welding a metal terminal to a battery cell electrode.

[0045] After the welding work is completed, Figure 3B As shown, driven by the swing arm 122 of the cylinder 120, the pusher claw 130 rotates from the working position toward the opposite side of the back plate 113. Specifically, Figure 3B The finger 130 on the left side rotates clockwise, and Figure 3B The pusher claw 130 on the right side rotates counterclockwise. During this rotation, the second arm portion 132 passes through the through hole 1130 in the back plate 113 in a manner that does not interfere with the back plate 113, so that the end of the second arm portion 132 abuts against the battery jig 200 and the battery jig 200 is ejected. By ejecting the battery jig 200 by the end of the second arm portion 132, sufficient torque is applied to the battery jig 200 from the second arm portion 132, ensuring that the battery jig 200 can be pushed out. In addition, it is also possible that the battery jig 200 that has been welded can be demolded from the side of the battery jig 200 while the battery jig 200 is pushed out by the force from the end of the second arm portion 132.

[0046] As described above, the material-dispensing device 100 realizes both the insertion and removal of the battery fixture 200 by only one set of the cylinder 120 and the finger 130. Figure 3A , Figure 3B The dial-in, dial-out and welding operations are performed to realize the automation of the battery cell welding production line.

[0047] In addition, in the above-mentioned embodiment, an example of using the cylinder 120 (swing cylinder) as a driving mechanism is illustrated, but other hydraulic, electromagnetic and other driving mechanisms may be used instead of the cylinder 120. In addition, in the above-mentioned embodiment, an example of the material-dispensing device 100 being used to implement the welding operation of the battery to be operated in the battery fixture 200 is illustrated, but the material-dispensing device 100 may also be used for other automated operations, such as the electrical characteristics detection of the battery. In addition, the shapes and sizes of the first arm portion 131 and the second arm portion 132 may also be variously deformed as needed.

The embodiments described above are only specific examples of the present invention, which are used to understand the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make various modifications, combinations and reasonable omissions of elements to the embodiments based on the technical ideas of the present invention, and the resulting methods are also included in the scope of the present invention.
