Description

Technical Field

[0001] The invention relates to the technical field of display screen testing, and in particular to a pole piece grabbing mechanism and a transfer device. Background Art

[0002] With the rapid development of the new energy industry, lithium batteries have been widely used as important energy storage components. In the manufacturing process of lithium batteries, the preparation of pole pieces is a key process. Pole pieces usually need to go through steps such as punching and drying, and finally be cut into small pieces with certain specifications and sizes. These cut pole pieces need to be transferred to subsequent processes for further processing into battery cells.

[0003] At present, the common way to transfer pole pieces is to use a robot with a vacuum suction cup. Figure 1 As shown, after the pole piece 14 is cut into a specified size, it will be sent to a specified position via the conveyor 2. At this time, a vacuum suction cup 51 is installed on the execution end of the manipulator 1, which is used to absorb and transfer the pole piece 14. The manipulator 1 and the vacuum suction cup 51 assembly on its execution end move back and forth between the placement platform 15 and the conveyor 2 in an "n"-shaped motion path, and each time a pole piece 14 is transferred, it needs to go back and forth along the path once. Although this traditional method of transferring the pole piece 14 can achieve accurate placement of the pole piece 14, due to its long motion path, the efficiency of the entire transfer process is low, which limits the overall production capacity of the production line. Therefore, how to improve the efficiency of the pole piece transfer process and reduce the number of times the manipulator moves back and forth between the conveyor and the placement platform has become a technical problem that needs to be solved urgently.

[0015] Compared with the prior art, the present invention provides a pole piece grabbing mechanism and a transfer device, which have the following beneficial effects:

[0016] 1. The present invention realizes the functions of grabbing and temporarily storing the electrode pieces by setting a frame with a guide groove, a temporary storage platform, an adsorption component and a driving element. When the driving element drives the adsorption component to move along the guide groove and absorb the electrode pieces on the conveyor, they can be temporarily stored on the temporary storage platform. When a sufficient number of electrode pieces are accumulated on the temporary storage platform, the manipulator will transfer these electrode pieces to the placement platform next to it.

[0018] 3. The present invention realizes the function and effect of automatically smoothing the pole piece when grabbing the pole piece by providing a suction component having a rod body, an elastic plate and a plurality of suction nozzles. The suction component of this structure solves the problem of suction difficulty caused by uneven pole pieces and ensures that the suction nozzle can more effectively suck the pole piece;

[0019] 4. The present invention provides a temporary storage platform with two side plates and two flip plates. When all the electrodes in the storage tank need to be placed on the placement platform, the storage tank only needs to be moved to the top of the placement platform, and then the two flip plates are synchronously controlled to flip downward, so that the electrodes can be smoothly transferred from the storage tank to the placement platform;

[0020] 5. The present invention provides a temporary storage platform with a flip plate, a torsion spring and a transmission structure that cooperates with the receiving box. When transferring the pole piece in the storage slot to the receiving box, it only needs to control the up and down movement of the frame to drive the flip plate to rotate through the transmission cooperation of the ring gear and the spur gear, thereby completing the transfer of the pole piece from the storage slot to the receiving box. The structure is simple and practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example: See Figures 1 to 12According to one aspect of an embodiment of the present invention, a pole piece grabbing mechanism is provided, which is assembled at the execution end of the manipulator 1 and is used to grab the pole piece 14 on the conveyor 2. The conveyor 2 is preferably a belt 182-type conveyor 2. The pole piece grabbing mechanism includes a frame 4 connected to the execution end of the manipulator 1, a temporary storage platform 7 arranged on the frame 4, an adsorption component 5 at the bottom that can produce vacuum adsorption on the pole piece 14, and a driving element 8; the adsorption component 5 is slidably connected to the frame 4 through a strip-shaped guide groove 6, the guide groove 6 has an A end and a B end, the adsorption component 5 is arranged relative to the temporary storage platform 7 along a first direction when it is at the A end, and is arranged relative to the temporary storage platform 7 along a second direction when it is at the B end, and the second direction is perpendicular to the first direction, Figure 8 In the embodiment, the first direction and the second direction are respectively the width direction and the height direction of the frame 4; the driving element 8 is configured to drive the adsorption assembly 5 to slide between the A end and the B end. Specifically, in this example, the A end of the guide groove 6 is arranged along the height direction of the frame 4, and the B end of the guide groove 6 is connected to the top of the A end of the guide groove 6 and gradually extends obliquely upward from the A end of the guide groove 6 toward the temporary storage platform 7.

[0036] In the above scheme, when the adsorption component 5 is driven by the driving element 8 to slide along the guide groove 6, the electrode 14 on the conveyor 2 can be sucked and the electrode 14 can be first stored on the temporary storage platform 7. When the number of electrode 14 stacked on the temporary storage platform 7 is large, the manipulator 1 will transfer these electrode 14 on the temporary storage platform 7 to the placement platform 15 next to the conveyor 2. In this way, when transporting the same number of electrode 14, the number of times the manipulator 1 moves back and forth between the conveyor 2 and the placement platform 15 can be reduced, thereby improving the efficiency of transporting the electrode 14.

[0037] like Figure 4 and Figure 7As shown, in this exemplary embodiment, a first slider 9 is fixedly provided at both ends of the adsorption component 5, the first end of the first slider 9 is cylindrical and slidably cooperates with the guide groove 6, and the second end is square; the driving element 8 includes a driving frame 80 and a first cylinder 81 that drives the driving frame 80 to move along the first direction, and the driving frame 80 is provided with a long first slide groove 82 arranged along the first direction and slidably cooperates with the second end of the first slider 9. Specifically, the guide groove 6 is arranged through the frame body 4. In the process of the first cylinder 81 driving the driving frame 80 to move up and down, the guide groove 6 and the first slide groove 82 always have an overlapping part in their orthographic projection along the length direction of the frame body 4. The first slider 9 is arranged through the overlapping part, that is, the first end of the first slider 9 is located in the guide groove 6 of the overlapping part, and the second end of the first slider 9 is located in the first slide groove 82 of the overlapping part. Since the second end of the first slider 9 is square, the second end of the first slider 9 cannot rotate when sliding in the first slide groove 82. This can ensure that the adsorption component 5 is not rotated during the sliding process along the guide groove 6, thereby ensuring the directional stability of the adsorption component 5 when adsorbing the pole piece 14 on the conveyor 2, so that it maintains a better adsorption effect.

[0038] like Figure 4 As shown, in the first embodiment, the adsorption assembly 5 includes a rod body 50 and a plurality of vacuum suction cups 51, the rod body 50 is slidably connected to the frame body 4 through the guide groove 6, and the plurality of vacuum suction cups 51 are arranged at intervals along the length direction of the rod body 50. The suction nozzle 53 of the vacuum suction cup 51 can be connected to a vacuum pump or a compressed air system through a pipeline (not shown). When it is necessary to grab the pole piece 14 on the conveyor 2, the vacuum suction cup 51 is brought close to or fitted with the pole piece 14, and the air in the vacuum suction cup 51 is extracted by a vacuum pump or a compressed air system to form a vacuum area in the vacuum suction cup 51, and the pole piece 14 can be sucked by the vacuum suction cup 51. When it is necessary to release the pole piece 14, a small amount of air is introduced into the vacuum suction cup 51 to break the vacuum state and reduce the pressure difference between the inside and the outside, so that the pole piece 14 is detached from the vacuum suction cup 51. The adsorption assembly 5 can exert force at multiple points on the pole piece 14 through multiple vacuum suction cups 51. After being sucked up, the pole piece 14 can maintain a relatively straight state. When the pole piece 14 is released, the pole piece 14 can fall more smoothly.

[0039] like Figure 5As shown, in the second embodiment, the adsorption assembly 5 includes a rod body 50, a rubber soft belt 52 and a plurality of suction nozzles 53. The rod body 50 is slidably connected to the frame body 4 through the guide groove 6. The two ends of the soft belt 52 are bent upward and fixedly connected to the bottom of the rod body 50. The plurality of suction nozzles 53 are arranged at intervals along the length direction of the soft belt 52. The suction nozzle 53 is connected to the vacuum pump or compressed air system through a pipeline (not shown). The principle of suction and release of the pole piece 14 by the suction nozzle 53 is the same as the principle of suction and release of the pole piece 14 by the vacuum suction cup 51 in the first embodiment. The difference is that when it is necessary to grab the pole piece 14 on the conveyor 2, the control rod body 50 is moved down, and the middle part of the soft belt 52 will first contact the middle part of the pole piece 14. As the rod body 50 continues to move down, the soft belt 52 will press the middle part of the pole piece 14 while pushing the two ends of the pole piece 14, thereby achieving the effect of smoothing the pole piece 14, reducing the bending degree of the pole piece 14, and making it easier for the suction nozzle 53 to absorb the pole piece 14.

[0040] like Figure 6 As shown, in the third embodiment, the adsorption assembly 5 includes a rod body 50, an elastic plate 54 and a plurality of suction nozzles 53. The rod body 50 is slidably connected to the frame body 4 through a guide groove 6. Both ends of the elastic plate 54 are slidably connected to the rod body 50 along the length direction of the rod body 50. The plurality of suction nozzles 53 are arranged at intervals along the length direction of the elastic plate 54. The suction nozzles 53 are connected to a vacuum pump or a compressed air system through a pipeline (not shown). Both ends of the elastic plate 54 are rotatably connected to a second slider 55 through a second rotating shaft 57. A second slide groove 56 slidably matched with the second slider 55 is provided on the rod body 50. When it is necessary to grab the pole piece 14 on the conveyor 2, the control rod body 50 is moved downward, and the middle part of the elastic plate 54 will first contact the middle part of the pole piece 14. As the rod body 50 continues to move downward, the middle part of the elastic plate 54 will press the middle part of the pole piece 14 while pushing toward the two ends of the pole piece 14. The second sliders 55 at the two ends of the elastic plate 54 will slide in the second slide groove 56 until the elastic plate 54 is straight, thereby also achieving the effect of smoothing the pole piece 14, ensuring the flatness of the pole piece 14, and making it easier for the suction nozzle 53 to suck the pole piece 14.

[0041] like Figure 8As shown, in this exemplary embodiment, the temporary storage platform 7 includes two side plates 70 and two flip plates 71. A storage slot 72 with both upper and lower openings is formed between the two side plates 70 and the frame 4; the two flip plates 71 are rotatably connected to the two sides of the lower opening of the storage slot 72. The two flip plates 71 serve as the bottom plate of the storage slot 72. When the two flip plates 71 are rotated to a horizontal state, the bottom of the storage slot 72 is closed. At this time, the electrode 14 released from the adsorption component 5 can be lowered into the storage slot 72 through the opening at the top of the storage slot 72, and finally supported on the two flip plates 71. When it is necessary to uniformly place the electrode 14 in the storage slot 72 on the placement platform 15, it is only necessary to move the storage slot 72 to the top of the placement platform 15, and then control the two flip plates 71 to flip downward synchronously, so that the electrode 14 can be smoothly transferred from the storage slot 72 to the placement platform 15. It can be understood that the flip plate 71 can be rotatably connected to the frame 4 or to the side plate 70, and the method of rotationally connecting the flip plate 71 to these components and the method of driving the flip plate 71 to rotate can adopt any method known to those skilled in the art.

[0042] like Fig. 9 , Fig.10 and Fig.11As shown, in this exemplary embodiment, the flip plate 71 has a first side and a second side relative to each other, and the first side of the flip plate 71 is rotatably connected to the frame 4 via a first rotating shaft 13, and a torsion spring (not shown) is provided at the rotating connection between the two, and the torsion spring is sleeved on the first rotating shaft 13, one end of the torsion spring is fixed to the frame 4 or the side plate 70, and the other end of the torsion spring is fixed to the flip plate 71, and the flip plate 71 has an annular gear 10 arranged circumferentially around the first rotating shaft 13, and the transfer equipment also includes a structural receiving box 12 with an opening at the upper end, and straight teeth 11 that can mesh with the annular gear 10 for transmission are provided on both sides of the opening of the receiving box 12. In specific implementation, the receiving box 12 is fixedly placed on the placement platform 15 with the opening facing upward, and the flip plate 71 is kept in a horizontal state under the elastic force of the torsion spring. At this time, the pole piece 14 can be stored in the storage slot 72. When the pole pieces 14 in the storage slot 72 need to be uniformly placed on the placement platform 15, the storage slot 72 is first moved to the top of the receiving box 12, and then the frame 4 is controlled to move downward by the manipulator 1, and the two flip plates 71 are driven to overcome the elastic force of the torsion spring by the transmission cooperation of the spur gear 11 and the ring gear 10, so that the pole piece 14 is placed from the storage slot 72 to the receiving box 12. After the pole piece 14 is transferred to the receiving box 12, the frame 4 is controlled to move upward, and the flip plate 71 can be flipped upward under the elastic force of the torsion spring and reset to a horizontal state. In this process, only the up and down movement of the frame 4 is controlled to drive the flip plate 71 to rotate, thereby completing the transfer of the pole piece 14 from the storage slot 72 to the receiving box 12, and the structure is simple and practical. It should be noted that in order to prevent the flip plate 71 from being pressed down by the weight of the pole piece 14 and rotating while storing the pole piece 14, in this example, a torsion spring with a suitable stiffness can be selected according to the total amount of pole pieces 14 stored in the storage slot 72 as required.

[0043] Furthermore, the second sides of the two flip plates 71 can be flipped upward under the elastic force of the torsion spring and placed in the storage slot 72; the temporary storage platform 7 also includes a supporting plate 73, which can be placed in the storage slot 72 and supported by the second sides of the two flip plates 71. In this example, the supporting plate 73 serves as the bottom plate of the storage slot 72. When no pole piece 14 is placed on the supporting plate 73, the depth of the storage slot 72 is the smallest. The supporting plate 73 is closest to the adsorption assembly 5 located at the B end of the guide slot 6. This can shorten the falling distance of the pole piece 14. Since the supporting plate 73 is elastically arranged in the storage slot 72 under the action of the flip plate 71 and the torsion spring, as the number of pole pieces 14 on the supporting plate 73 increases, the supporting plate 73 gradually moves downward in the storage slot 72, and the depth of the storage slot 72 gradually increases, so that the falling distance of each pole piece 14 is basically the same. This can ensure that the storage slot 72 can store as many pole pieces 14 as possible, and can also shorten the falling distance of the pole pieces 14, so that the pole pieces 14 are neatly placed in the storage slot 72.

[0044] In the above scheme, since the carrying plate 73 will fall into the receiving box 12 together with the pole pieces 14 when the pole pieces 14 in the storage slot 72 are uniformly placed in the receiving box 12, it is necessary to put the carrying plate 73 back into the storage slot 72 after each discharge, which is very troublesome. Figure 3 and Fig.12 As shown, in this exemplary embodiment, a load-bearing plate conveying device is provided on the placement platform 15, and the load-bearing plate conveying device includes a mounting frame 16, a second cylinder 17 and a storage 18. The cylinder is installed on the placement platform 15 through the mounting frame 16, and the storage 18 is fixed on the output shaft of the cylinder. The second cylinder 17 can drive the storage to move along the width direction of the frame 4. The frame 4 is provided with a window 40 for the storage 18 to pass through. The storage 18 includes a frame 180 and two groups of transmission mechanisms arranged in the frame 180. Each group of the transmission mechanisms includes two transmission shafts 181 and belts 182 tightly mounted on the two transmission shafts 181. The transmission shaft 181 can be driven by a motor (not shown). The motor drives the transmission shaft 181 to rotate, thereby driving the belt 182 to rotate. The outer side of the belt 182 is protrudingly provided with limit protrusions 183 equidistantly arranged along the length direction of the belt 182, and the distance between two adjacent limit protrusions 183 is not less than the thickness of the load-bearing plate 73. In specific implementation, multiple carrier plates 73 can be placed on the limiting protrusions 183 on the facing side of the two groups of belts 182. When the carrier plate 73 in the storage slot 72 is placed in the receiving box 12 together with the pole piece 14, the manipulator 1 can control the frame 4 to move up a certain distance, so that the flip plate 71 flips upward and resets under the elastic force of the torsion spring, and then the storage device 18 is driven to move by the second cylinder 17, so that the storage device 18 passes through the opening of the frame 4 and comes to the top of the storage slot 72. Then, the motor is used to drive the transmission shaft 181 and the belt 182 to rotate, so that the lowest carrier plate 73 between the two groups of belts 182 is lowered into the storage slot 72, thereby realizing the automatic addition of the carrier plate 73 into the storage slot 72.

[0045] According to another aspect of an embodiment of the present invention, a transfer device is provided, such as Figure 2 As shown, the above-mentioned electrode piece grabbing mechanism also includes a visual camera 3, and the visual camera 3 and the electrode piece grabbing mechanism are arranged in sequence along the conveying direction of the conveyor 2. The visual camera 3 can be used to identify the position of the electrode piece 14 on the conveyor 2. According to the information provided by the visual camera 3, the manipulator 1 can accurately grab the electrode piece 14 from the conveyor 2 and accurately place the electrode piece 14 on the placement platform 15 or the receiving box 12 on the placement platform 15, thereby improving the neatness of the electrode piece 14 after placement.

[0046] Working principle: The electrode pieces 14 cut into small pieces are transported by the conveyor 2 and are identified by the visual camera 3. The visual camera 3 transmits the position information of the electrode pieces 14 to the manipulator 1. The manipulator 1 adjusts the position of the frame 4 according to this information to ensure that the adsorption component 5 is aligned with the electrode piece 14 on the conveyor 2. Subsequently, the driving element 8 is started, causing the adsorption component 5 to move down along the guide groove 6 and grab the electrode piece 14 by vacuum adsorption. The adsorbed electrode piece 14 moves up with the component to the top of the temporary storage platform 7 and is released there. The electrode piece 14 is temporarily stored on the temporary storage platform 7. When the number of electrode pieces 14 on the temporary storage platform 7 is large enough, the manipulator 1 will transfer these electrode pieces 14 to the placement platform 15 next to it. This reduces the frequent movement of the manipulator 1 between the conveyor 2 and the placement platform 15, and improves the overall transportation efficiency.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
