[0044] See also Figure 1 The automatic material taking device provided in the embodiment of the present application is now described. The automatic material taking device provided in the embodiment of the present application comprises a moving mechanism 20 and a clamping mechanism 30.

[0045] The material frame 60 contains a plurality of workpieces, which are arranged in sequence along the first direction X and the second direction Y. The workpieces are arranged in at least two columns along the first direction X and in at least two rows along the second direction Y. The first direction X and the second direction Y are arranged at an angle. The angle between the first direction X and the second direction Y can be an acute angle or a right angle.

[0046] In the embodiment of the present application, the workpiece is a battery cell, the first direction X is perpendicular to the second direction Y, that is, the angle is a right angle, and the first direction X and the second direction Y are both horizontal. During production, these workpieces 61 need to be taken out of the material frame 60 to facilitate the operation of the next process.

[0047] Reference Figure 1 and Figure 2 The moving mechanism 20 includes a moving part 21 that can translate along a third direction Z, the third direction Z is set at an angle with the first direction X, and the third direction Z is set at an angle with the second direction Y. The moving part 21 of the moving mechanism 20 can move along the first direction X and the third direction Z. Among them, the angle between the first direction X and the third direction Z can be an acute angle or a right angle; the angle between the second direction Y and the third direction Z can be an acute angle or a right angle. In some embodiments of the present application, the angle between the first direction X and the third direction Z is a right angle, and the angle between the second direction Y and the third direction Z is a right angle.

[0048] It is understandable that when it is necessary to take the material, the material frame 60 containing the workpiece 61 is placed on one side of the moving part 21 along the third direction Z by manual or conveying mechanism, and the moving part 21 can approach or move away from the workpiece 61 in the material frame 60 along the third direction Z. In the embodiment of the present application, the first direction X is the left-right direction, the third direction Z is the up-down direction, and the second direction Y is the left-right direction. That is, the material frame 60 is conveyed or placed below the moving part 21, and the moving part 21 can move up and down to cooperate with the clamping mechanism 30 to descend to clamp the workpiece 61 and take the workpiece 61 out of the material frame 60.

[0049] Reference Figure 2 The moving mechanism 20 may include an X-axis translation mechanism 22 and a Z-axis translation mechanism 23. The Z-axis translation mechanism 23 is arranged on the X-axis translation mechanism 22, and the X-axis translation mechanism 22 can drive the Z-axis translation mechanism 23 to move along the X-axis; the moving part 21 is arranged on the Z-axis translation mechanism 23, and the Z-axis translation mechanism 23 can drive the moving part 21 to move along the Z-axis. Through the mutual cooperation of the X-axis translation mechanism 22 and the Z-axis translation mechanism 23, the moving part 21 can be moved to a specified position within a certain range. Both the X-axis translation mechanism 22 and the Z-axis translation mechanism 23 can adopt servo motors. In the embodiment of the present application, the X-axis is along the left-right direction, the Z-axis is along the up-down direction, and the Y-axis is along the front-back direction. After descending to clamp a workpiece and the workpiece 61 is taken away or placed, the X-axis translation mechanism 22 can translate along the first direction X with the clamping claw mechanism 30 and move to the top of the next workpiece in the material frame.

[0050] Reference Figure 1 and Figure 3The clamp mechanism 30 includes a mounting structure, an opening and closing driver 31 disposed on the mounting structure, a first clamp 32 and two second clamps 33, the mounting structure is connected to the moving part 21, the first clamp is connected to the mounting structure, the two second clamps 33 are located on both sides of the first clamp 32 along the second direction Y, a clamping opening facing away from the mounting structure is formed between the first clamp and the second clamp, and the clamping opening is disposed toward the material frame along the third direction Z. The opening and closing driver 31 is used to drive the second clamp 33 to approach the first clamp 32 to clamp the workpiece, or to move away from the first clamp 32 to release the workpiece.

[0051] That is, in the clamping mechanism 30, the second clamping piece 33 can be clamped and released by approaching and moving away from the first clamping piece 32. There are two second clamping pieces 33, which are respectively located on both sides of the first clamping piece 32. The two second clamping pieces 33 are driven to move by the opening and closing driver 31, while the first clamping piece 32 remains stationary. After the moving part 21 moves to the top of the workpiece 61, when clamping the workpiece 61, the opening and closing driver 31 first drives the second clamping piece 33 away from the first clamping piece 32 to open the clamping jaws.

[0052] It can be understood that, when released, the position of the first clamp 32 corresponds to the gap between the two workpieces 61 of the workpiece group, and the position of the second clamp 33 corresponds to the gap between the workpiece 61 and the material frame 60 .

[0053] After the first clamp 32 and the second clamp 33 are opened, since the positions of the two clamps and the gap correspond, when the movable part 21 drives the clamping port to move along the third direction Z close to the transportation mechanism 10, the second clamp 33 can be inserted between the workpiece 61 and the material frame 60, and the first clamp 32 can be inserted between the two workpieces 61 without damaging the workpiece 61. Then the opening and closing driver 31 drives the second clamp 33 to approach the first clamp 32, clamping the workpiece 61 between the first clamp 32 and the second clamp 33. The movable part 21 rises again to take the workpiece 61 out of the material frame 60.

[0054] Based on the above structure, during the material removal process, the first clamp 32 can be inserted between two adjacent workpieces 61, and each workpiece 61 to be removed can be clamped by the first clamp 32 and the second clamp 33. Not only can two workpieces 61 be removed at the same time, thereby improving work efficiency, but also during the removal process, the two workpieces 61 can be prevented from abutting against each other to cause damage to the workpieces, thereby ensuring good structural integrity and high yield rate of the workpieces.

[0055] Reference Figure 3, the first clamp 31 is connected to the mounting structure in a sliding manner along the second direction Y. Due to the different manufacturing processes and the placement positions of the workpieces 61 in the material frame 60, there will be errors in the spacing between adjacent workpieces 61. If the first clamp 32 is fixedly connected to the mounting structure, when the workpiece 61 is offset, the gap between the first clamp 32 and the two adjacent workpieces 61 is not aligned, and it cannot be inserted into the gap. The first clamp 32 will fall and crush the workpiece 61. For this reason, in the embodiment of the present application, the connection between the first clamp 32 and the mounting structure is set to be sliding. When the workpiece 61 is slightly offset due to the processing technology and the placement position, the first clamp 32 can be adjusted in a sliding manner along the second direction Y, aligned with the gap between the two adjacent workpieces 61, and correctly inserted into the gap, thereby avoiding damage to the workpiece 61. It can be understood that the sliding of the first clamp 32 on the driver body 311 is small-scale, and it only slides in the gap between the workpieces 61.

[0056] Reference Figure 3 , the lower end of the first clamp 31 has inclined guide surfaces on both sides along the second direction Y. In the embodiment of the present application, the first clamp 32 is set to slide. When the workpiece 61 is slightly offset due to the processing technology and the placement position, the first clamp 32 can be in contact with the workpiece 61 by the guide surface 321 of the first clamp 32 during the descent process, and the first clamp 32 can be pushed to be offset from the workpiece 61 and automatically inserted into the gap between the workpieces 61, thereby avoiding damage to the workpiece 61.

[0057] Reference Figure 3 The opening and closing driver 31 includes a driver body 311 and driving ends 312 located at both ends of the driver body 311. The driver body 311 is arranged on the mounting structure, and the two driving ends 312 can move toward or in opposite directions. The second clamp 33 is arranged on the driving end 312, and the first clamp 32 is connected to the driver body 311 and is located in the middle between the two second clamps 33. That is, the opening and closing driver 31 has two driving ends 312, and the two driving ends 312 are used to drive the second clamp 33 to move, and the first clamp 32 is arranged on the driver body 311. When the second clamp 33 moves, although the first clamp 32 does not move, the second clamp 33 can still approach or move away from the first clamp 32, that is, one first clamp 32 cooperates with two second clamps 33, that is, two clamps can be formed to clamp two workpieces 61 at the same time. Specifically, the opening and closing driver 31 is a clamp cylinder.

[0058] Reference Figure 3 The first clamping piece 32 is connected to the mounting structure through the driver body 311. The first clamping piece 32 is slidably connected to the driver body 311. That is, the first clamping piece 32 can move on the driver body 311 to adapt to the position deviation of the workpiece 61 caused by the manufacturing process and the different placement positions of the workpiece 61 in the material frame 60.

[0059] Reference Figure 3 A slide rail may be installed on the driver body 311, a slider is installed on the slide rail, and the first clamp 32 is installed on the slider, so that the first clamp 32 can slide on the driver body 311. In order to limit the sliding range of the first clamp 32, limit blocks may be provided at both ends of the slide rail on the driver body 311. When the first clamp 32 slides and hits the limit blocks, it cannot slide further, thereby preventing the first clamp 32 from sliding too far and running out of the spacing area between the two workpieces 61.

[0060] Reference Figure 3 and Figure 4 The automatic material picking device of the embodiment of the present application also includes a flipping mechanism. The flipping mechanism 40 includes a flipping shaft 41, a first connecting head 42, a second connecting head 43 and a telescopic drive 44. Both ends of the flipping shaft 41 are rotatably connected to the moving part 21. The mounting structure is connected to the flipping shaft 41. The first connecting head 42 is fixedly connected to the flipping shaft 41. The telescopic drive 44 is hinged to the moving part 21. The second connecting head 43 is arranged at the output end of the telescopic drive 44. The second connecting head 43 is hinged to the first connecting head 42.

[0061] Reference Figure 3 , two shaft brackets are provided on the moving part 21, and shaft brackets are provided with shaft holes, and the two ends of the flip shaft 41 are inserted into the shaft holes, so that the flip shaft 41 can rotate. After the flip shaft 41 is installed on the moving part 21, the axis is horizontal. In order to facilitate rotation, a bearing can be provided in the shaft hole to facilitate smoother rotation of the flip shaft 41. A hinge fulcrum is provided on the moving part 21 above the flip shaft 41, and the upper end of the telescopic driver 44 is hinged to the hinge fulcrum, so that the telescopic driver 44 can rotate to a certain extent to adapt to the movement during telescopic and flipping. The first hinge joint is fixedly connected to the flip shaft 41, and the axis of the hinge between the first hinge joint and the second hinge joint is parallel to the flip shaft 41. The hinge point between the first hinge joint and the second hinge joint is at a certain distance from the output end of the flip shaft 41 and the telescopic driver 44. When the output end moves, it will drive the hinge point to move, thereby driving the flip shaft 41 to rotate. Since the mounting structure of the clamp mechanism 30 is connected to the flip shaft 41 , when the flip shaft 41 rotates, the mounting structure and the first clamping piece 32 , the second clamping piece 33 , and the opening and closing driver 31 connected to the mounting structure are driven to rotate together.

[0062] Reference Figure 5 and Figure 6The telescopic driver 44 has an extended state and a retracted state. In the extended state, the flip shaft 41 rotates to make the clamping opening face the material frame along the third direction. In the retracted state, the flip shaft 41 rotates to make the clamping opening face the first direction. That is, through the extension and retraction of the output end, the hinge point is driven to move, and then the flip shaft 41 is driven to rotate, so that the clamping claw mechanism 30 connected to the flip shaft 41 rotates, changes the direction of the clamping opening, and switches between the third direction and the first direction, and then clamps the workpiece 61 when facing the material frame. After clamping the workpiece 61, it is flipped to face the first direction to place the workpiece 61 to the next station.

[0063] In the embodiment of the present application, the first direction X is the left-right direction, the third direction Z is the up-down direction, when the output end of the telescopic driver 44 is extended, the clamping port faces downward, and when the output end of the telescopic driver 44 is retracted, the clamping port faces right.

[0064] Reference Figure 4 The first connector 42 includes a first fixing portion 421 and a first hinged portion 422 vertically connected to one end of the first fixing portion 421. One end of the first fixing portion 421 away from the first hinged portion 422 is fixedly connected to the flip shaft 41. That is, the first connector 42 is fixed to the flip shaft 41 through the first fixing portion 421, and is hinged to the second connector 43 through the first hinged portion 422. It can be understood that the first fixing portion 421 is provided with a connection hole matching the flip shaft 41, and the size of the connection hole can be adjusted, so that the hole diameter can be reduced after the flip shaft 41 is inserted, and the flip shaft 41 is fixed. The first hinged portion 422 is provided with a pin hole, which can be inserted with a pin, and the pin is also inserted into the second connector 43, so that the first hinged portion 422 and the second connector 43 are hinged through the pin.

[0065] Reference Figure 4 The second connector 43 includes a second fixing portion 431 and a second hinged portion 432 disposed at one end of the second fixing portion 431. The end of the second fixing portion 431 away from the second hinged portion 432 is fixedly connected to the output end, and the second hinged portion 432 is hinged to the first hinged portion 422. That is, the second connector is fixed to the output end through the second fixing portion 431, and is hinged to the first connector 42 through the second hinged portion 432. It can be understood that the second hinged portion 432 is provided with a pin hole, into which a pin can be inserted, and the pin is also inserted into the pin hole of the first hinged portion 422, so that the first hinged portion 422 and the second hinged portion 432 are hinged through the pin.

[0066] Reference Figure 3 and Figure 5, the mounting structure of the flip mechanism 40 includes a connecting plate 45 and a mounting plate 46, one end of the connecting plate 45 is fixedly connected to the flip shaft 41, the other end of the connecting plate 45 is fixedly connected to the mounting plate 46, the opening and closing driver 31 is arranged on the mounting plate 46, and the first clamp 32 is arranged on the opening and closing driver 31. That is, the flip shaft 41 is connected to the opening and closing driver 31 through the connecting plate 45 and the mounting plate 46. Specifically, the opening and closing driver 31 is installed on the mounting plate 46, and the mounting plate 46 is connected and fixed to the flip shaft 41 through the connecting plate 45. The connecting plate 45 and the flip shaft 41 can be fixed by welding. In some embodiments, the connecting plate 45 is fixed to the flip shaft 41 along the radial direction of the flip shaft 41, and the mounting plate 46 is vertically connected to the connecting plate 45.

[0067] Reference Figure 3 and Figure 6 The flipping mechanism 40 also includes a first limiting structure 47, which includes a first buffer 471 and a first limiting plate 472. The first buffer 471 is fixed on the moving part 21 and arranged downward. One end of the first limiting plate 472 is vertically connected to the connecting plate 45. When in the extended state, the other end of the first limiting plate 472 abuts against the first buffer 471 from bottom to top to make the clamping opening face the third direction Z. That is, the first limiting mechanism is used to limit the flipping of the clamping mechanism 30 so that the clamping opening faces the third direction Z to prevent over-flipping. In the embodiment of the present application, the third direction Z is a vertical direction. When the clamping mechanism 30 changes from a horizontal state to a vertical state, it needs to rotate downward 90°. If it is over-flipped, there will be deviations when the first clamp 32 and the second clamp 33 are inserted into the material frame 60, which may cause damage to the workpiece 61. Therefore, the embodiment of the present application is provided with a first buffer 471 and a first limit plate 472. When the clamping mechanism 30 flips, the first limit plate 472 flips downward at the same time. When the clamping mechanism 30 rotates to a vertical state, the first limit plate 472 contacts the first buffer 471, thereby preventing the clamping mechanism 30 from continuing to flip downward, ensuring that the clamping mechanism 30 can only rotate to a vertical state. Specifically, the first buffer 471 can be a spring buffer or an oil pressure buffer. Specifically, the first limit plate 472 is arranged on the left end surface of the connecting plate 45.

[0068] Reference Figure 3 and Figure 6The flipping mechanism 40 further includes a second limiting structure 48, which includes a second buffer 481 and a second limiting plate 482. The second buffer 481 is fixed on the moving part 21 and arranged upward, and the second limiting plate 482 is arranged in an L shape. One end of the second limiting plate 482 is vertically connected to the connecting plate 45, and the other end is parallel to the connecting plate 45 and extends in a direction away from the clamping opening. In the retracted state, the other end of the second limiting plate 482 abuts against the second buffer 481 from top to bottom so that the clamping opening faces the first direction X. That is, the second limiting mechanism is used to limit the flipping of the clamping mechanism 30 so that the clamping opening faces the first direction X, thereby preventing over-flipping. In the embodiment of the present application, the first direction X is a horizontal left-right direction. When the clamp mechanism 30 changes from a vertical state to a horizontal state, it needs to be rotated upward by 90°. If it is overturned, when the workpiece 61 is placed on the receiving platform of the next station (for example, on the assembly line of the workpiece 61), the workpiece 61 itself is tilted, and one end is easily impacted when it falls, causing damage to the workpiece 61. Therefore, the embodiment of the present application is provided with a second buffer 481 and a second limit plate 482. When the clamp mechanism 30 is turned over, the second limit plate 482 is turned upward at the same time. When the clamp mechanism 30 is rotated to a horizontal state, the second limit plate 482 contacts the second buffer 481, thereby preventing the clamp mechanism 30 from continuing to turn upward, ensuring that the clamp mechanism 30 can only be rotated to a horizontal state. Specifically, the second buffer 481 can be a spring buffer or an oil pressure buffer. Specifically, the second limit plate 482 is arranged on the right end face of the connecting plate 45. Due to its L-shaped structure, it can abut against the second buffer 481 set upward when it is turned upward.

[0069] Reference Figure 3 The clamping mechanism 30 also includes a plurality of insulating protection blocks 34, which are arranged on the first clamping piece 32 or the second clamping piece 33 and correspond to the position of the electrode 611 on the workpiece 61. In the embodiment of the present application, the workpiece 61 is a battery cell on which an electrode is arranged. The insulating protection block 34 is made of insulating material, which is fixed on the first clamping piece 32 or the second clamping piece 33 and the position corresponds to the position of the electrode 611 on the workpiece 61. When the first clamping piece 32 and the second clamping piece 33 clamp the workpiece 61, the insulating protection block 34 can shield the electrode 611 to prevent the electrode 611 from contacting with other metal parts of the clamping piece, causing a short circuit and causing danger.

[0070] Among them, refer to Figure 1 and Figure 2The automatic material-retrieving device further includes a conveying mechanism 10, which can convey the material frame 60 along a first direction X. The conveying direction is the first direction X, which is the same as the arrangement direction of the workpiece 61 in the material frame, that is, the placement direction of the material frame on the conveying mechanism is fixed. When the worker puts the material frame 60 on the conveying mechanism 10, the arrangement direction of the material frame 60 can be placed parallel to the conveying direction of the conveying mechanism. In the embodiment of the present application, the first direction X is the left-right direction, and the conveying mechanism 10 conveys the material frame 60 from the left to the right. Specifically, the conveying mechanism 10 can be a double-speed chain.

[0071] Reference Figure 1 The automatic material-retrieving device further includes a lifting mechanism 50, which is located below the conveying mechanism 10. The lifting mechanism 50 has a lifting part 51 that can be raised and lowered to lift the material frame 60 on the conveying mechanism 10. The lifting mechanism 50 can lift the material frame 60 on the conveying mechanism 10, and cooperate with the lowering of the lifting part to facilitate the clamping mechanism 30 to clamp the workpiece 61. The lifting mechanism 50 may include a lifting cylinder, which drives the lifting part 51 to lift and lower the material frame 60, and the lowered material frame 60 falls on the conveying mechanism 10.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
