Description

Technical Field

[0001] The utility model relates to a guide plate position correction mechanism. Background Art

[0002] The battery guide plate (also called the terminal connecting piece) is a commonly used connecting component in battery production. In the large-scale production process of batteries, a large number of guide plates often need to be grasped, positioned, moved and spot welded at the same time. Therefore, it is necessary to use a guide plate fixture and an automatic grasping mechanism for positioning multiple guide plates.

[0003] The commonly used battery conductor is a long metal strip, and its two ends can be used to weld to the electrode terminals of two single cells respectively, so as to electrically connect the two single cells in series or in parallel. As a specific example of a battery conductor, Figure 4 As shown, the battery conductor (5) has two edge portions (5a) and a bent portion (5b) located in the center. The edge portion (5a) is used for welding with the electrode terminal of the single battery, and the bent portion (5b) is used for conductor positioning or preventing the stacking of multiple battery conductors. According to specific needs, the center of the battery conductor may not have a bent portion, and may be formed into a straight long strip shape.

[0004] In the prior art, a guide plate fixture (1) for positioning the above-mentioned battery guide plate is as follows: Figure 5 As shown, it is a roughly rectangular cuboid, on one surface of which a plurality of fixed blocks (12) are formed, and the gaps between these fixed blocks (12) form a guide plate groove (11), which is composed of a shallow groove (11a) and a central deep groove (11b), and can be used to accommodate a plurality of guide plates (5). Among them, the plurality of fixed blocks (12) are arranged on both sides of the width direction of the guide plate fixture (1), and a shallow groove (11a) is formed between adjacent fixed blocks (12) in each column, which is used to accommodate the edge portion (5a) of the guide plate (5), and a central deep groove (11b) is formed between the two columns, which is used to accommodate the curved portion (5b) of the guide plate (5). The respective shapes and depths of the shallow groove (11a) and the central deep groove (11b) match the shape and thickness of the battery guide plate. In the case where the battery guide plate is a straight long strip, the depths of the shallow groove (11a) and the central deep groove (11b) can also be consistent.

[0005] By using such a guide plate jig (1), a plurality of guide plates (5) can be neatly placed and positioned on the surface of the guide plate jig (1) using a robot, making it easier for the suction cup mechanism to absorb and transfer the plurality of guide plates as a whole, thereby improving the production efficiency of the battery.

[0006] However, due to the objective errors in the processing accuracy of battery components (such as jigs) and the movement of the robot, when the guide plate is placed in the jig, the guide plate often deflects or is not placed in place. This will have a certain impact on the operation time of the equipment. In addition, when switching to battery guide plates of other sizes or shapes, there is a problem that it is difficult to replace the jig and the corresponding models are relatively single.

[0010] The piston rod (22) of the cylinder (2) is located below the central deep groove (11b) and is connected to the plurality of movable stoppers (13) above.

[0011] Driven by the cylinder (2), the plurality of movable blocks (13) can move forward and backward along the central deep groove (11b), thereby correcting the position of the battery guide plate (5) placed in the guide plate groove (11).

[0012] Preferably, in the length direction of the guide plate fixture (1), the length of the fixed stopper (12) is greater than the length of the movable stopper (13).

[0013] Preferably, in the length direction of the guide plate fixture (1), the width of the shallow groove (11a) is greater than the width of the battery guide plate (5).

[0028] The specific form of the guide plate position correction mechanism of the present invention is described below in conjunction with the accompanying drawings.

[0029] Figure 1 It is a schematic diagram showing the structure of the guide plate position correction mechanism of the present invention.

[0030] like Figure 1 As shown, the guide plate position correction mechanism of the utility model comprises: a guide plate fixture (1) and a cylinder (2); the surface of the guide plate fixture (1) is provided with a guide plate groove (11) which can accommodate a plurality of battery guide plates (5); and the cylinder (2) is located at one end of the guide plate fixture (1) in the length direction.

[0031] In this specification, the longitudinal direction of the guide plate jig (1) is also referred to as the front-rear direction, and the width direction orthogonal to the longitudinal direction is also referred to as the left-right direction. Among them, one end of the longitudinal direction where the cylinder (2) is located is referred to as the front end.

[0032] like Figure 2 As shown, the surface of the guide plate fixture (1) has a plurality of fixed blocks (12) and a plurality of movable blocks (13), and the plurality of fixed blocks (12) are arranged in two left and right rows on both sides of the width direction of the guide plate fixture (1), separating the left and right shallow grooves (11a) and the central deep groove (11b). The left and right shallow grooves (11a) and the central deep groove (11b) form the guide plate groove (11).

[0033] Specifically, a plurality of fixed blocks (12) are separated into two left and right columns in the width direction of the guide plate fixture (1), and are arranged at intervals along the length direction of the guide plate fixture (1). A shallow groove (11a) is formed between two adjacent fixed blocks (12) in each column, and a central deep groove (11b) is formed between the fixed blocks (12) in the left and right columns. A plurality of movable blocks (13) are located in the central deep groove (11b), that is, respectively located between each pair of fixed blocks (12) in the left and right columns. Figure 2 In the embodiment, the movable stopper (13) is in the form of a small square block separated from the left and right and closely attached to the fixed stopper (12), but it is not limited thereto and may also be a whole block between a pair of fixed stoppers (12).

[0034] As described above, the commonly used battery guide plate (5) has a curved portion (5b) and two edge portions (5a) on the left and right sides. When such a battery guide plate (5) is placed in the guide plate groove (11), the two edge portions (5a) fall into the shallow grooves (11a) respectively, and the curved portion (5b) falls into the central deep groove (11b). In other words, the battery guide plate (5) is placed in the guide plate groove (11) in a manner orthogonal to the length direction of the guide plate jig (1), and multiple battery guide plates (5) are placed along the length direction of the guide plate jig (1). Figure 2 In the embodiment, eight battery guide plates (5) can be placed, but this is not limited thereto.

[0035] Furthermore, if Figure 3 As shown, the cylinder (2) has a driver (21) located at one end of the guide plate fixture (1) in the longitudinal direction and a piston rod (22) arranged below the central deep groove (11b), and the piston rod (22) is connected and linked to a plurality of movable blocks (13) above. Under the action of an external electromagnetic valve, the cylinder (2) drives the plurality of movable blocks (13) to move forward and backward along the central deep groove (11b) through the piston rod (2), thereby correcting the position of the battery guide plate (5) placed in the guide plate groove (11).

[0036] In the guide plate position correction mechanism of the utility model, a cylinder that can pull the movable stopper forward and backward to correct the position of the battery guide plate is added on the basis of the original guide plate fixture. Through the position correction action of the cylinder, the battery guide plate can be accurately positioned, which can solve the problem of guide plate deviation or misplacement.

[0037] Next, the action mechanism of the guide plate position correction mechanism of the present invention is described in detail.

[0038] When the cylinder (2) is not started, the front edge of each pair of movable blocks (13) is aligned with the front edge of each pair of fixed blocks (12). At this time, sufficient space is left between the front and rear pairs of fixed blocks (12), so that the manipulator can absorb multiple battery guides (5) in sequence and quickly place them into the guide groove (11). However, since the width of the shallow groove (11a) (i.e., the distance between the two side walls of the shallow groove) is greater than the width of the battery guide (5), the positioning of the battery guide (5) can only be roughly performed by relying on the shallow groove (11a). Therefore, although the battery guide (5) is easy to place into the guide groove (11), the placed battery guide (5) may be skewed, and the position needs to be corrected through subsequent operations.

[0039] Next, the cylinder (2) is started, and the piston rod (22) drives the movable block (13) to move forward along the central deep groove (11b). During the movement, when the front edge of the movable block (13) hits the battery guide plate (5), it pushes the battery guide plate (5) to move forward together. When the battery guide plate (5) (specifically, the edge portion (5a)) abuts against the side wall of the shallow groove (11a) located on the front side, the sensor of the cylinder (2) senses the resistance and stops in time, that is, the piston rod (22) stops moving. At this time, the distance between the front edge of the movable block (13) and the rear edge of the front pair of fixed blocks (12) (that is, the side wall of the shallow groove (11a) located on the front side) is exactly equal to the width of the battery guide plate (5), and the battery guide plate (5) is positioned against the front side wall of the shallow groove (11a), so that the arrangement in the guide plate groove (11) becomes neat.

[0040] Therefore, the position of the battery guide plate (5) can be positioned more accurately through the guide plate position correction mechanism of the utility model.

[0041] In the utility model, since the piston rod (22) and the movable stopper (13) are both arranged in the central deep groove (11b), even when the battery guide plate is in a straight long strip shape, the depth of the central deep groove (11b) is greater than the depth of the shallow grooves (11a) on the left and right sides.

[0042] In the length direction of the guide plate fixture (1), the length of the fixed stopper (12) is preferably greater than the length of the movable stopper (13), so that the guide plate can be smoothly inserted and the movable stopper (13) can be easily moved forward and backward.

[0043] As described above, in order to facilitate the manipulator to place the battery guide plate (5) into the guide plate groove, it is preferred that the width of the shallow groove in the guide plate groove (i.e., the distance between the two side walls of the shallow groove) is set to a value greater than the width of the guide plate. In other words, in the length direction of the guide plate fixture (1), it is preferred that the gap between the adjacent fixed stoppers (12) on the left and right sides is greater than the width of the battery guide plate (5) (or the width of the edge portion (5a) of the guide plate), so that it can more flexibly correspond to different guide plate sizes.

[0044] In the utility model, when the battery conductor is in the shape of a straight long strip, the thickness or width of the battery conductor is the thickness or width of the entire conductor; when the battery conductor is in a special shape, such as a shape with a curved portion in the center, the thickness or width of the battery conductor depends on the position, and may refer to the thickness or width of the edge portions (5a) on both sides of the battery conductor (5), or the thickness or width of the center including the curved portion (5b).

[0045] In addition, the depth of the shallow groove (11a) is preferably greater than the thickness of the battery guide plate (5), that is, the thickness of the edge portion (5a). In this way, the battery guide plate can be limited by the side wall of the shallow groove (11a), thereby improving the positioning accuracy.

[0046] In addition, the thickness (i.e., height) of the movable stopper (13) is preferably greater than the thickness of the battery guide plate (5). In the case where the battery guide plate (5) has a curved portion at the center, the thickness of the battery guide plate (5) includes the height of the curved portion (5b) protruding downward. In this way, the movable stopper (13) can abut against the curved portion (5b) when moving forward, thereby pushing the battery guide plate (5) to move together and reach a designated position.

[0047] In the case where no pressure sensor is provided in the cylinder (2), the moving distance of the piston rod (22) can also be set in advance so that when the movable stopper (13) stops moving, the distance between the front edge of the movable stopper (13) and the rear edge of the front pair of fixed stops (12) is exactly equal to the width of the battery guide plate (5).

[0048] In addition, the guide plate fixture (1) and the cylinder (2) are preferably fixed on the base (3). At this time, in order to improve the stability of the piston rod, the piston rod (22) of the cylinder (2) can be connected to a positioning slider (4), and the positioning slider (4) can be slid on the surface of the base (3) along the length direction of the guide plate fixture (1), thereby further improving the positioning accuracy.

[0049] By using the guide plate position correction mechanism of the utility model, multiple battery guide plates are placed on the guide plate fixture and accurately positioned, so the suction cup mechanism can be directly used to simultaneously absorb the multiple guide plates and transfer them as a whole to the subsequent process. In this way, the tilting phenomenon of the battery guide plate during the installation process can be effectively solved, the operating accuracy of the manipulator and the accuracy requirements of image recognition are reduced, and the processing accuracy requirements of the fixture are reduced, so that the machine structure is simplified and the debugging process of the debugging personnel is simplified.

[0050] Specifically, by designing the appropriate sizes of the central deep groove (11b) and the shallow groove (11a) in the guide plate groove (11), the guide plate (5) can be neatly positioned on the surface of the guide plate fixture (1), so that it is convenient to use an automatic grasping mechanism (such as a robot) to place multiple (8 in the figure) guide plates in the guide plate fixture (1) for positioning, and then use a suction cup mechanism to absorb and transfer the multiple guide plates as a whole.

[0051] In addition, since the size of the guide plate groove (11) is not required to strictly match the size of the battery guide plate (5), it can be flexibly applied to battery guide plates (5) of various sizes, thereby improving the utilization efficiency of the guide plate fixture (1).

[0052] The guide plate position correction mechanism of the utility model adds a cylinder that can be pulled forward and backward on the basis of the original guide plate fixture, which can correct the placement of the battery guide plate in the fixture and prevent various inappropriate situations such as guide plate deflection, floating or asymmetric position. This structure can achieve accurate positioning of the guide plate, solve the problem of guide plate deflection or misplacement, not only improve the utilization efficiency of the guide plate fixture, but also simplify the process and improve production efficiency.

[0053] The guide plate position correction mechanism of the present invention is described above through the accompanying drawings and specific implementation methods, but the present invention is not limited to the above-mentioned specific implementation methods. Various deformations or element changes can be made without departing from the main purpose of the present invention, and these deformations or element changes are also included in the protection scope of the present invention.
