DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, the workpiece transfer device 100 of some embodiments of the present application includes a first base 110 and a clamping mechanism 120. The first base 110 is provided with a preset position. The clamping mechanism 120 includes a bracket 121, a clamping assembly 122 and a correction assembly 123. The clamping assembly 122 and the correction assembly 123 are both installed on the bracket 121. The clamping assembly 122 is used to grasp the workpiece 200. After the clamping assembly 122 drives the workpiece 200 to move to the preset position, the correction assembly 123 is used to correct the position of the workpiece 200 to ensure that the workpiece 200 reaches the preset position.

[0028] It can be understood that if there is a position deviation of the workpiece 200 in the preset position, the correction component 123 can move the workpiece 200 so that it is in the preset position with a preset posture; if the workpiece 200 is already in the preset position with a preset posture, the correction component 123 is used to reconfirm the posture of the workpiece 200, and the workpiece 200 will not be moved again during the correction process, thereby ensuring that regardless of whether there is a position deviation of the workpiece 200, the workpiece 200 can be ensured to be in the preset position with a preset posture after correction.

[0029] In some embodiments of the present application, the workpiece 200 is an adapter plate for realizing conductive connection between the tab and the pole of the battery cell. After the workpiece 200 is corrected to reach a preset position, ultrasonic welding is performed after the battery cell loading and positioning are completed; in other embodiments, the workpiece 200 may also be other thin plate structure products with higher positioning accuracy.

[0030] The workpiece transfer device 100 of the embodiment of the present application is used to transfer the workpiece 200. After the workpiece 200 reaches the preset position, the correction component 123 is used to further correct the position of the workpiece 200, thereby improving the position accuracy of the workpiece 200 at the preset position, so that other devices can process the workpiece 200 at the preset position. This not only has a simple structure and is convenient for debugging, but also can improve the processing accuracy and processing qualification rate of the workpiece 200.

[0031] In some embodiments of the present application, the upper surface of the first base 110 is recessed to form a positioning groove 112 , and the positioning groove 112 is used to accommodate the workpiece 200 . When the workpiece 200 is located in the positioning groove 112 , the workpiece 200 reaches a preset position.

[0032] The clamping mechanism 120 is located on an upper side of the first base 110 . The upper surface of the first base 110 refers to a surface of the first base 110 along the vertical direction Z close to the clamping mechanism 120 .

[0033] The clamping mechanism 120 loads the workpiece 200 from the upper side of the first base 110 to the positioning groove 112. The contour of the positioning groove 112 matches the contour of the workpiece 200. After the workpiece 200 reaches the preset position, the correction component 123 corrects the position of the workpiece 200 to ensure that the workpiece 200 falls into the positioning groove 112.

[0034] This arrangement not only ensures that the workpiece 200 reaches the preset position, but also prevents the workpiece 200 from being offset during the machining process.

[0035] In other embodiments, the positioning groove 112 may not be provided, and the position of the workpiece 200 may be fixed by vacuum adsorption or other methods.

[0036] In some embodiments of the present application, the clamping jaw assembly 122 is a vacuum suction cup, and the clamping jaw mechanism 120 further includes a driving assembly for driving the bracket 121 to move.

[0037] like Figure 4 As shown, the bracket 121 includes a connecting plate 1211 and a clamping stand 1212. The connecting plate 1211 is used to connect to the execution end of the driving assembly. The upper side of the clamping stand 1212 is connected to the connecting plate 1211, and the bottom side is configured as the clamping assembly 122.

[0038] The execution end of the driving assembly is installed with a connecting plate 1211 of the bracket 121. The driving assembly is configured to drive the clamping jaw assembly 122 to move through the bracket 121 to carry the workpiece 200 to move and switch between the material picking position and the preset position.

[0039] The bottom wall of the clamping stand 1212 is a vacuum adsorption plate with multiple adsorption holes, which is used to grab the workpiece 200 by adsorption; the interior of the clamping stand 1212 is provided with a vacuum adsorption device for providing negative pressure for the adsorption holes.

[0040] With this arrangement, the workpiece 200 can be simply and reliably grasped, and the transfer and transport of the workpiece 200 can be achieved.

[0041] In other embodiments, the gripper assembly 122 may also be a finger cylinder structure, etc.

[0042] In some embodiments of the present application, the clamping jaw assembly 122 is disposed on the bottom side of the bracket 121 , and a plurality of correction assemblies 123 are provided, and the plurality of correction assemblies 123 are spaced apart along the circumference of the bracket 121 .

[0043] The bottom side of the bracket 121 refers to the side of the clamping stand 1212 of the bracket 121 facing the first base 110 along the vertical direction Z; the peripheral side of the bracket 121 refers to the side wall of the clamping stand 1212 of the bracket 121 surrounding the vertical axis.

[0044] The upper side of the clamping frame 1212 is connected to the connecting plate 1211, and a correction component 123 is provided on the peripheral side. The clamping component 122 is located at the bottom of the clamping frame 1212.

[0045] like Figure 4 As shown, for example, four correction assemblies 123 are spaced apart along the periphery of the gripper frame 1212 and positioned at corresponding correction points based on the contour characteristics of the workpiece 200. The gripper frame 1212 can be fixedly connected to the bottom side of the connecting plate 1211 or can be rotatably adjusted relative to the connecting plate 1211 to facilitate deviation correction or workpiece 200 posture switching.

[0046] With this arrangement, the position of the workpiece 200 can be corrected at multiple points along the circumference of the bracket 121 , thereby ensuring that the workpiece 200 reaches a preset position.

[0047] In other embodiments, the number of correction components 123 may be three, five, six, etc.; an abutment structure may also be provided on the first base 110, with one side of the workpiece 200 abutting against the abutment structure, and the other side being corrected using the correction component 123 to ensure that the workpiece 200 reaches the preset position.

[0048] like Figure 3 As shown, in some embodiments of the present application, the correction component 123 includes a driving member 1231 and a push rod 1232, the push rod 1232 includes a first end 1233 and a second end 1234, the first end 1233 is rotatably mounted on the bracket 121, and the second end 1234 is used to correct the position of the workpiece 200; the driving member 1231 is installed on the bracket 121, and is used to drive the push rod 1232 to switch between an open position and a retracted position, and the push rod 1232 is configured to move from the open position to the retracted position to correct the workpiece 200 to a preset position.

[0049] The first end 1233 is mounted to the clamping frame 1212 via a hinge shaft, with the axis of the hinge shaft parallel to the surface of the hinge portion of the clamping frame 1212. The second end 1234 abuts against the workpiece 200, pushing the workpiece 200 to move and correct the posture and position of the workpiece 200. In a preferred embodiment, the axial direction of the hinge shaft extends horizontally to minimize the length of the push rod 1232 and minimize the space occupied during rotation. In other embodiments, the axial direction of the hinge shaft may also extend obliquely relative to the horizontal plane (i.e., the XY plane).

[0050] The driving member 1231 is mounted on the clamping jaw stand 1212 and is used to drive the push rod 1232 to switch between the open position and the retracted position.

[0051] When the push rod 1232 is in the open position, the second end 1234 is away from the clamping jaw stand 1212 ; when the push rod 1232 moves toward the retracted position, the second end 1234 gradually approaches the clamping jaw stand 1212 and corrects the position of the workpiece 200 .

[0052] It can be understood that when the push rod 1232 is in the retracted position, the second end 1234 of the push rod 1232 of each correction assembly 1232 is disposed on the contour line of the workpiece 200 .

[0053] Through this arrangement, the second end 1234 of the push rod 1232 can be brought into contact with the workpiece 200 to push the workpiece 200 to move and correct the position of the workpiece 200; compared with the traditional method of setting a telescopically driven push block on the first base 110 to correct the workpiece 200, the push rod 1232 is installed on the clamp stand 1212, and the clamp assembly 122 leaves after loading the workpiece 200 to the preset position, thereby allowing sufficient space on the first base 110 to arrange other devices to process the workpiece 200.

[0054] In other embodiments, the correction component 123 may also abut against the workpiece 200 by reciprocating translation to correct the position of the workpiece 200 .

[0055] In some embodiments of the present application, the driving member 1231 is an electromagnet, and the push rod 1232 is a permanent magnet.

[0056] An opening is provided on the side of the clamping jaw stand 1212 and has a cavity structure inside. The electromagnet is installed inside the clamping jaw stand 1212. The position of the opening is set corresponding to the push rod 1232. The electromagnet can act on the push rod 1232 through the opening.

[0057] The electromagnet generates a repulsive force on the permanent magnet when energized, and generates an attractive force on the permanent magnet when the current is in the opposite direction, thereby driving the push rod 1232 to switch between the extended position and the retracted position.

[0058] Through this setting, a non-physical connection structure between the push rod 1232 and the driving member 1231 can be achieved, and the push rod 1232 can be driven to rotate by magnetic attraction and repulsion, thereby simplifying the structure of the correction component 123; and the electromagnetic control method can control the opening amplitude of each push rod 1232 by adjusting the current size respectively, so the debugging process is relatively convenient and the consistency requirements of the fixture are low.

[0059] In other embodiments, the driving member 1231 may also be a telescopic cylinder, with two ends respectively connected to the bracket 121 and the push rod 1232.

[0060] like Figure 5 As shown, in some embodiments of the present application, the first base 110 is provided with an avoidance groove 111, and the avoidance groove 111 is provided corresponding to the push rod 1232, for avoiding the corresponding push rod 1232 from switching between the open position and the retracted position.

[0061] For example, there are four push rods 1232, two of which are arranged opposite to each other along the first direction X, and the other two push rods 1232 are arranged opposite to each other along the second direction Y. Four avoidance grooves 111 are correspondingly arranged, two of which extend along the first direction X, and the other two avoidance grooves 111 extend along the second direction Y. The push rods 1232 and the avoidance grooves 111 are arranged in a one-to-one correspondence.

[0062] Through this setting, when the push rod 1232 moves from the open position to the retracted position, the second end 1234 gradually approaches the workpiece 200 until it reaches the contour line of the workpiece 200 to correct the position of the workpiece 200. The second end 1234 passes through the corresponding avoidance groove 111 to ensure that the correction process proceeds smoothly.

[0063] In other embodiments, a protruding platform may be provided on the upper side of the first base 110 , where the platform is significantly higher than other portions of the first base 110 , so that there are no obstacles near the workpiece 200 , thereby reducing the possibility of obstacles in the moving path of the push rod 1232 .

[0064] Furthermore, the workpiece transfer device 100 is equipped with two clamping jaw assemblies 122. The bracket 121 includes a connecting plate 1211 and two clamping jaw stands 1212. The two clamping jaw assemblies 122 share the same connecting plate 1211. Each clamping jaw assembly 122 is mounted on a corresponding clamping jaw stand 1212. Each clamping jaw assembly 122 is respectively equipped with a correction assembly 123, which can achieve a single-beat transfer of two workpieces 200. Correspondingly, the first base 110 is provided with a corresponding avoidance groove 111 for each push rod 1232 of each clamping jaw assembly 122.

[0065] As a preferred embodiment, the two clamping jaw assemblies 122 are spaced apart along the first direction X, and the corresponding avoidance grooves 111 of the two push rods 1232 of the two clamping jaw assemblies 122 that are close to each other along the first direction X are connected to each other in the first base 110 to simplify the structure of the first base 110.

[0066] like Figure 6 As shown, in some embodiments of the present application, the workpiece transfer device 100 further includes a second base 130 having a material picking position, and the clamping jaw assembly 122 is configured to grab the workpiece 200 from the material picking position and transfer it to a preset position of the first base 110 .

[0067] The upper side of the second base 130 along the vertical direction Z is used to carry the workpiece 200 . The workpiece 200 is loaded to a preset position by other devices or manually so that the clamping jaw assembly 122 can pick up the workpiece.

[0068] For example, the workpiece 200 is an adapter, and the first base 110 is a welding station for the battery cell tab and the adapter; the second base 130 is a feeding station for the adapter, and the clamping jaw assembly 122 grabs the workpiece 200 from the picking position of the second base 130, transfers it to the preset position of the first base 110, and releases the workpiece 200 after correction by the correction assembly 123, completing the transfer process of the workpiece 200.

[0069] Through this arrangement, the workpiece 200 can be transferred fully automatically, thereby improving the processing efficiency of the workpiece 200.

[0070] like Figure 6 As shown, in some embodiments of the present application, the second base 130 is provided with a push block assembly 131, which is arranged around the material picking position and is used to correct the position of the workpiece 200 to ensure that the workpiece 200 reaches the material picking position.

[0071] The push block assembly 131 is disposed on the upper side of the second base 130 along the vertical direction Z. After the workpiece 200 is loaded onto the second base 130 , the push block assembly 131 abuts against the workpiece 200 to correct the position of the workpiece 200 so that the workpiece 200 grasped by the clamping jaw assembly 122 has a fixed posture.

[0072] It is understandable that when the clamping jaw assembly 122 picks up materials from the picking position, the push rod 1232 can be in an open state to avoid the push block assembly 131, and the clamping jaw assembly 122 extends into the picking position to grab the workpiece 200.

[0073] Through this setting, the position accuracy of the clamping assembly 122 in grasping the workpiece 200 at the material picking position can be improved, so that there is a smaller position deviation when unloading at the preset position, and the correction range of the correction assembly 123 is reduced, thereby allowing the correction accuracy and correction efficiency of the correction assembly 123 to be improved.

[0074] In some embodiments of the present application, the push block assembly 131 includes a plurality of push blocks, and the plurality of push blocks are arranged around the material taking position.

[0075] like Figure 6As shown, for example, the push block assembly 131 includes a first push block 1311, a second push block 1312, a first fixed block 1313, and a second fixed block 1314, which are arranged around the material removal position. The first fixed block 1313 and the second fixed block 1314 are fixedly disposed on the upper side of the second base 130. The first fixed block 1313 is configured to abut against the workpiece 200 along a first direction X, and the second fixed block 1314 is configured to abut against the workpiece 200 along a second direction Y. Driven by respective cylinders, the first push block 1311 pushes the workpiece 200 along the first direction X, thereby pressing the workpiece 200 against the first fixed block 1313. The second push block 1312 pushes the workpiece 200 along the second direction Y, thereby pressing the workpiece 200 against the second fixed block 1314.

[0076] Through this arrangement, the position of the workpiece 200 can be corrected along the first direction X and the second direction Y simply and reliably.

[0077] Based on the aforementioned embodiment of "two gripper assemblies 122 sharing a common connecting plate 1211, and spaced apart along the first direction X," the second base 130 is provided with two retrieving positions, simultaneously providing two workpieces 200 per cycle. Each retrieving position is equipped with a corresponding pusher assembly 131. A first fixed block 1313 is positioned between the two retrieving positions along the first direction X, and the two retrieving positions share the same first fixed block 1313. A second fixed block 1314 is positioned on the same side of the two retrieving positions along the second direction Y, and the two retrieving positions share the same second fixed block 1314, thereby simplifying the structure of the second base 130.

[0078] like Figures 1 to 6 As shown, the working principle of the workpiece transfer device 100 of the embodiment of the present application is as follows:

[0079] The workpiece 200 is loaded to the unloading position of the second base 130 . The first push block 1311 and the second push block 1312 abut against the workpiece 200 along the first direction X and the second direction Y, pushing the workpiece 200 against the first fixing block 1313 and the second fixing block 1314 to correct the position of the workpiece 200 .

[0080] When the electromagnet is energized, it generates a repulsive force on the push rod 1232, and the push rod 1232 is in the open position. The clamping jaw assembly 122 takes the material from the material taking position of the second base 130 by vacuum adsorption.

[0081] Under the action of the driving assembly, the clamping jaw assembly 122 carries the workpiece 200 and moves to a preset position of the first base 110 , and roughly places the workpiece 200 into the positioning groove 112 ;

[0082] The electromagnet gradually reduces the current and switches the current direction until it generates an attraction force on the push rod 1232. The push rod 1232 moves downward toward the stowed position, passing through the avoidance groove 111. The second end 1234 lands on the contour line of the workpiece 200. The position of the workpiece 200 is corrected at multiple points to ensure that the workpiece 200 falls into the positioning groove 112.

[0083] The clamping jaw assembly 122 releases the workpiece 200 , completing the transfer process of the workpiece 200 .

[0084] The workpiece transfer device 100 of the embodiment of the present application is used to transfer the workpiece 200. Since the workpiece 200 is corrected at both the material removal position and the preset position, especially the electromagnetic control method is used to correct the workpiece 200 at the preset position, the correction accuracy of each correction point can be flexibly adjusted, thereby improving the correction effect. When applied to the adapter welding process, the position of the adapter can be further corrected after the adapter is loaded onto the welding fixture, thereby improving the welding quality between the adapter and the battery cell and increasing the qualified rate of the finished battery cell assembly.

[0085] After the workpiece 200 reaches the preset position, the correction component 123 is used to further correct the position of the workpiece 200, thereby improving the position accuracy of the workpiece 200 at the preset position, so that other devices can process the workpiece 200 at the preset position. This not only has a simple structure and is convenient for debugging, but also can improve the processing accuracy and processing qualification rate of the workpiece 200.

[0086] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0087] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
