[0002] At present, many lithium battery manufacturers propose the requirement of detecting bare cells before assembling in the production process, that is, the appearance of bare cells needs to be detected before assembling after the cells are offline.

In addition, the terms "first", "second" are just used to distinguish in the description, and have no special meaning.

[0039] The following refers to Figures 1 to 4 The material moving device and the lithium battery production equipment provided by the utility model are described.

[0040] The lithium battery production equipment includes a lithium battery cutting and folding machine (not shown in the figure), a conveying device (not shown in the figure) and a material moving device, wherein the lithium battery cutting and folding machine is any cutting and folding machine in the prior art that can automatically produce battery cells 100 and automatically discharge, and the specific structure is not limited. The conveying device is connected to the discharge end of the lithium battery cutting and folding machine, and the conveying device is any device that can convey battery cells 100 in the prior art, which can be a belt conveying device or a chain plate conveying device. In this embodiment, the belt conveying device is taken as an example, and the belt conveying device has a carrier (not shown in the figure), and the finished battery cells 100 are placed in the carrier for conveying.

[0041] It should be noted that the carrier includes a bottom plate and support blocks, three of which are connected along the length direction of the battery cell 100 on the surface of the bottom plate, and the battery cell 100 is placed on the carrier, and the battery cell 100 is horizontally overlapped on the support blocks, that is, the bottom of the battery cell 100 corresponds to the position between the adjacent two support blocks. Since the two ends of the battery cell 100 have the easily deformed and easily damaged tab 101, only the middle support block is connected with the limiting plate 52 along the width direction of the battery cell 100, that is, only the battery cell 100 is limited in the width direction of the battery cell 100, and the battery cell 100 has a degree of freedom in the length direction of the battery cell 100.

[0042] In the prior art, when the battery cell 100 is initially transplanted to the carrier, all the battery cells 100 are located at the target position; since the battery cell 100 needs to be detected by manual offline visual inspection during offline conveying, that is, the battery cell 100 is first taken out and detected, and then the battery cell 100 is placed in the carrier, but the carrier only limits the battery cell 100 in the width direction of the battery cell 100, so that after the battery cell 100 is placed in the carrier, the actual position of the battery cell 100 in the length direction of the battery cell 100 deviates from the target position, and the deviation of each battery cell 100 is different, thereby affecting the subsequent accurate material moving operation.

[0043] In order to solve the above problems, the embodiment of the utility model also provides a material moving device, which aims to accurately pick up the battery cell 100 with position deviation and correct the position of the battery cell 100, so that each battery cell 100 can be accurately transplanted to a fixed position. The specific structure of the material moving device is described below.

[0044] Reference Figure 1 And Figure 2 The material moving device includes a detection mechanism and a material moving mechanism, the detection mechanism is configured to detect the deviation of the target position and the actual position of the material in the first direction; the material moving mechanism is configured to transplant the material with deviation. The material in the embodiment is taken as an example of the battery cell 100, the first direction in the embodiment is the length direction of the battery cell 100, the second direction in the embodiment is perpendicular to the first direction, that is, the width direction of the battery cell 100, and the following is described in this direction.

[0045] The detection mechanism (not shown in the figure) includes a visual detection member and a controller. The visual detection member is located above the conveying device, and in this embodiment, the visual detection member is a detection camera, which can be connected to the ground or the conveying device through a support. In this embodiment, the detection camera is connected to the conveying device through a support, and the lens of the detection camera is arranged downward and aligned with the carrier on the conveying device. The controller is electrically connected with the detection camera, and the controller can analyze and process the pictures taken by the detection camera, and calculate the deviation of the actual position of the battery cell 100 in the first direction relative to the target position. The controller is electrically connected with all the execution components in the material moving mechanism, and the controller can control the execution components in the material moving mechanism to work, thereby realizing the automatic operation of the material moving mechanism.

[0046] With reference to Figure 1 and Figure 2 , the material moving mechanism includes a base 1, a lifting seat 2, a deviation rectifying seat 3, and a material taking assembly. The base 1 is located at the discharging end of the conveying device, and the base 1 can move along the horizontal direction relative to the carrier. The lifting seat 2 can lift along the vertical direction relative to the base 1. The deviation rectifying seat 3 is connected to the bottom of the lifting seat 2, and the deviation rectifying seat 3 can move along the first direction relative to the lifting seat 2 to compensate for the deviation. The material taking assembly is connected to the bottom of the deviation rectifying seat 3, and the material taking assembly includes a material taking gripper 4, which can move relative to the deviation rectifying seat 3 to insert into the bottom of the material and hold the material.

[0047] Through the above arrangement, before the lifting seat 2 is ready to move downward to pick up the battery cell 100 above the battery cell 100 to be picked up, the deviation rectifying seat 3 first slides along the first direction by a distance, which is the difference of the battery cell 100 in the first direction. Then, the lifting seat 2 drives the material taking gripper 4 to descend, so that the relative position of the material taking gripper 4 and the battery cell 100 in the first direction remains unchanged, thereby still accurately picking up the battery cell 100, so that the material taking gripper 4 is not easy to touch the battery cell 100. After grabbing the battery cell 100, the deviation rectifying seat 3 is reset to make the placement position of the battery cell 100 consistent each time, thereby improving the accuracy of material moving. In addition, the material taking gripper 4 inserts into the bottom of the battery cell 100 to hold the battery cell 100, which physically limits the battery cell 100 in the vertical direction, so that the battery cell 100 is not easy to be separated from the gripper, thereby improving the stability of holding.

[0048] Specifically, the base 1 is vertically arranged, and the movement of the base 1 is driven by a linear module or a two-axis module, which can be selected according to the actual scene. In this embodiment, only the linear module is taken as an example. The lifting seat 2 is located on one side of the base 1. The lifting seat 2 comprises a sliding plate 21, a lifting plate 22 and a side plate 23. The sliding plate 21 is vertically arranged and is in sliding connection with the base 1. The sliding plate 21 slides in the vertical direction. In this embodiment, the sliding of the sliding plate 21 is driven by a screw module and guided and limited by a linear guide rail. In other embodiments, the sliding plate 21 can also be driven by a driving member 56 such as an air cylinder or an electric cylinder. The lifting plate 22 is horizontally connected to the bottom of the sliding plate 21. The side plate 23 is vertically connected to the top of the lifting plate 22. The sliding plate 21 is located between the two side plates 23. By connecting the two side plates 23 between the lifting plate 22 and the sliding plate 21, the stability of the connection between the sliding plate 21 and the lifting plate 22 is improved.

[0049] Further, the deviation rectifying seat 3 is slidingly connected to the bottom of the lifting plate 22. The sliding direction of the deviation rectifying seat 3 is the first direction. The sliding mode of the deviation rectifying seat 3 is set by referring to the sliding mode of the sliding plate 21. The driving motor of the screw module is a servo motor, which can be controlled with high precision to accurately compensate for the deviation. In this embodiment, the deviation rectifying seat 3 is arranged in the horizontal direction. In this embodiment, two deviation rectifying seats 3 are taken as an example. The two deviation rectifying seats 3 are arranged in the second direction. The material taking assembly is provided with one on the bottom of each deviation rectifying seat 3. Therefore, the material moving mechanism can move two battery cells 100 at a time, thereby improving the efficiency of material moving. In other embodiments, the number of deviation rectifying seats 3 can be three, four or more. The plurality of deviation rectifying seats 3 can also be arranged in the first direction.

[0050] Reference Figure 2 Further, two groups of material taking seats 5 are arranged at the bottom of the deviation rectifying seat 3 in the second direction. At least one group of material taking clamps 4 is arranged on each material taking seat 5. Specifically, in this embodiment, two sliding seats 6 are slidingly connected to the bottom of each deviation rectifying seat 3 in the second direction. The two sliding seats 6 slide relative to each other, that is, the two sliding seats 6 move away from or close to each other when sliding. The sliding mode of the sliding seat 6 is set by referring to the sliding mode of the sliding plate 21, which will not be described here. A group of material taking seats 5 is slidingly connected to the bottom of each sliding seat 6. The material taking seats 5 slide in the vertical direction. In this embodiment, only one material taking seat 5 is arranged in each group of material taking seats 5. One group of material taking clamps 4 is arranged on each material taking seat 5. The two groups of material taking clamps 4 distributed on the two material taking seats 5 are arranged opposite to each other.

[0051] Based on the above settings, the material taking clamping jaw 4 is arranged on the material taking seat 5 which is connected to the sliding seat 6 in the vertical direction, and the material taking seat 5 naturally falls under the action of gravity of both the material taking seat 5 and the material taking clamping jaw 4, that is, the material taking seat 5 will always be in the lowest position, and when the material taking clamping jaw 4 abuts against the obstacle (the battery cell 100 or other equipment) in the process of moving downward, the material taking clamping jaw 4 has the space for upward movement, so as to prevent damage to the obstacle and the material taking clamping jaw 4, and to protect the battery cell 100 and the equipment.

[0052] In addition, since the two sliding seats 6 slide relative to each other, the two groups of material taking clamping jaws 4 distributed on the two material taking seats 5 also move relative to each other, and when the battery cell 100 is picked up, the two groups of material taking clamping jaws 4 can clamp the two sides of the battery cell 100 in the length direction respectively, so that the battery cell 100 is more evenly stressed, and the stability of the material moving operation is improved.

[0053] Referring to Figure 3 Further, the elastic members 61 are connected between the material taking seat 5 and the sliding seat 6, and the elastic members 61 are arranged in parallel with two, and the elastic members 61 in the embodiment are elastic telescopic rods, and in other embodiments, the elastic members 61 can also be springs. The sliding block 62 and the sliding rail 51 are connected to the material taking seat 5 and the sliding seat 6 respectively, and the sliding block 62 and the sliding rail 51 are in sliding fit, and in the embodiment, the sliding block 62 is connected to the sliding seat 6, and the sliding rail 51 is connected to the material taking seat 5, and the sliding block 62 and the sliding rail 51 are arranged in two. The limiting plate 52 is connected to the material taking seat 5, and the limiting plate 52 is arranged in two at the two ends of the material taking seat 5 in the length direction and in the vertical direction, one of the limiting plates 52 is located at the top of the sliding block 62, and the other limiting plate 52 is located at the bottom of the sliding block 62, and when the material taking seat 5 is in the lowest position, the limiting plate 52 at the top of the sliding block 62 abuts against the sliding block 62, and the limiting plate 52 at the bottom of the sliding block 62 is arranged in space from the sliding block 62. Thus, the cooperation of the sliding block 62 and the sliding rail 51 guides and limits the sliding of the material taking seat 5, and the material taking seat 5 is limited by the limiting plate 52 to prevent the material taking seat 5 from being separated from the sliding seat 6.

[0054] In order to further protect the equipment, the sensing sheet 53 is connected to the material taking seat 5, and the sensing sensor is connected to the sliding seat 6, and the sensing sensor in the embodiment is the photoelectric sensor 63, and the photoelectric sensor 63 is electrically connected to the controller, and when the material taking seat 5 is in the lowest position, the end of the sensing sheet 53 is in the sensing area of the photoelectric sensor 63. When the material taking seat 5 abuts against the obstacle and slides upward, the sensing sheet 53 will be separated from the sensing area of the photoelectric sensor 63, and at this time, the controller cannot sense the signal of the photoelectric sensor 63, and the operation of the equipment will be immediately stopped, and an alarm will be given, so as to further protect the equipment. Optionally, in some other embodiments, the sliding seat 6 can also be directly omitted.

[0055] Preferably, the number of the material taking clamps 4 in each group in the embodiment is preferably two, and the two material taking clamps 4 are distributed along the first direction, and the two material taking clamps 4 correspond to the two overhanging positions of the bottom of the battery cell 100 respectively, so that the four material taking clamps 4 stably clamp the battery cell 100, further improving the stability of material taking. In other embodiments, the number of the material taking clamps 4 in each group can also be three, four or more.

[0056] With reference to Figure 3 and Figure 4 , exemplarily, each material taking clamp 4 comprises a first claw part 41 and a second claw part 42, the first claw part 41 comprises a connecting part 411 and a supporting part 412, the top of the connecting part 411 is connected to the material taking seat 5, the bottom of the connecting part 411 is connected to the supporting part 412, the connecting part 411 and the supporting part 412 have an included angle therebetween, and the supporting part 412 can be inserted into the bottom of the material; in the embodiment, the connecting part 411 is vertically arranged, the supporting part 412 is horizontally arranged, i.e. the connecting part 411 and the supporting part 412 are vertically arranged, and the connecting part 411 and the supporting part 412 are integrally formed. In some other embodiments, the connecting part 411 and the supporting part 412 can be inclined to a certain extent, and the included angle between the connecting part 411 and the supporting part 412 can also be 85° or 95°, etc.

[0057] Further, the second claw part 42 is located above the supporting part 412 and is slidably connected to the material taking seat 5, and the second claw part 42 slides along the vertical direction. In the embodiment, a driving member 56 is slidably connected to each material taking seat 5 along the vertical direction, the driving member 56 is in the form of a horizontally arranged plate, the sliding of the driving member 56 is driven by a pneumatic cylinder, all the second claw parts 42 are connected to the bottom of the driving member 56, and the distance between the second claw part 42 and the first claw part 41 in the vertical direction is greater than the height of the battery cell 100.

[0058] Based on the above, when the material taking clamp 4 works, the material taking clamp 4 first descends to a position where the supporting part 412 is lower than the bottom of the battery cell 100, then the material taking seat 5 drives the material taking clamp 4 to move towards the battery cell 100, so that the supporting part 412 is located at the bottom of the battery cell 100, and the second claw part 42 is located at the top of the battery cell 100 at this time, then the material taking clamp 4 moves upwards to abut against the battery cell 100 through the supporting part 412, and the driving member 56 drives the second claw part 42 to move downwards until abutting against the top of the battery cell 100, so as to complete the clamping of the battery cell 100. The four material taking clamps 4 all work in the above-mentioned manner, so as to clamp the battery cell 100 from both sides in the length direction, and the four clamping points are distributed at the four corners of the battery cell 100, so as to stably clamp the battery cell 100.

[0059] In addition, the four supporting portions 412 support the battery cell 100, and the connecting portion 411 limits the battery cell 100, so that the battery cell 100 is prevented from falling in the case of sudden power failure or air failure of the equipment. In addition, the bottom end of each first claw portion 41 is covered with a rubber protective layer, so that soft contact is achieved between the first claw and the battery cell 100, thereby achieving the effect of protecting the battery cell 100.

[0060] With reference to Figure 3 and Figure 4 In order to adapt to different arrangement positions of the support block on the carrier and the length of the battery cell 100, the distance between the two material taking claws 4 in each group of material taking claws 4 is adjustable in the embodiment. Specifically, a waist hole 54 is formed on the material taking seat 5 corresponding to the position of each first claw portion 41 in the first direction, and a bolt is arranged in the waist hole 54. When the bolt is tightened, the head of the bolt abuts against the material taking seat 5, and the screw rod of the bolt is threadedly connected with the first claw portion 41. At this time, the material taking seat 5 is in a locked state. When the bolt is loosened, the bolt can slide in the first direction inside the waist hole 54, so that the distance between the two first claw portions 41 is adjusted. That is, the position of the two first claw portions 41 in the embodiment can be adjusted in the first direction. In other embodiments, only a single first claw portion 41 can be arranged in an adjustable form.

[0061] In addition, the side of the first claw portion 41 close to the material taking seat 5 is connected with a sliding block 413, the surface of the material taking seat 5 is provided with a sliding groove 55 in the first direction, and the sliding block 413 is in sliding fit with the sliding groove 55, so as to guide and limit the sliding of the first claw portion 41. A size mark is arranged at each waist hole 54, so as to improve the adjustment accuracy of the first claw portion 41.

[0062] Further, the position adjustment mode of each second claw portion 42 is arranged in reference to the position adjustment mode of the first claw portion 41, so that the position of the second claw portion 42 can be adjusted along with the position of the first claw portion 41, and finally the adaptability of the material taking assembly is improved.

[0063] The working process of the material moving device is as follows:

[0064] When the carrier carrying the battery cell 100 is conveyed to the lower side of the detection camera, the carrier is photographed by the detection camera, and the photographed photo is transmitted to the controller for analysis and processing, and the deviation of the actual position of the battery cell 100 in the first direction relative to the target position is calculated, and then the deviation is compensated by sliding the correction seat 3 by a distance in the first direction, so as to prepare for the subsequent accurate grabbing.

[0065] When the carrier with the battery cell 100 is conveyed below the base 1, the lifting seat 2 drives the two taking assemblies to move downward, in the process, the two sliding seats 6 move away from each other, so that the distance between the two groups of taking clamps 4 in each taking assembly is greater than the width of the battery cell 100, so as to avoid the collision between the taking clamps and the battery cell 100 when the taking clamps move downward; the taking clamps 4 stop moving downward when the supporting part 412 is below the bottom of the battery cell 100, and the two sliding seats 6 are controlled to move close to each other, so that the two groups of taking clamps 4 move towards the battery cell 100 until the supporting part 412 is located at the bottom of the battery cell 100, and then the lifting seat 2 drives the taking clamps 4 to move upward until the supporting part 412 abuts against the bottom of the battery cell 100, and the second claw part 42 moves downward to abut against the top of the battery cell 100, so that the precise taking of the battery cell 100 is completed.

[0066] Then, the battery cell 100 is transplanted to the unloading position through the movement of the base 1 and the lifting seat 2, in the process, the deviation correcting seat 3 is reset, so that the battery cell 100 is accurately placed in the unloading position, and the clamping of the battery cell 100 is completed according to the operation opposite to the taking of the battery cell 100, and finally the base 1 and the lifting seat 2 are reset, and the preparation for continuing to take the battery cell 100 is completed.
