[0001] The utility model relates to the technical field of battery production, and in particular to a battery core feeding device, a mechanism and battery production equipment. Background Art

[0002] The cell loading process is an important step in the battery manufacturing process. The cell is taken out from the tray by a robot or conveyor system with a clamp.

[0003] At present, the loading of square shell battery cells is carried out by clamping the battery cells in the tray in a manner that one clamp cylinder corresponds to one battery cell, so as to adapt to the different battery cell lengths in the X-axis direction of the tray.

At this time, it is necessary to replace the clamp of a different model. Due to the long time and large changes in the replacement, this will lead to low production efficiency and inconvenience in use. Utility Model Content

[0034] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] The main purpose of the utility model is to provide a battery cell feeding device 100 to solve the problem that the battery cell feeding method in the prior art cannot simultaneously meet the compatible adjustment in the X and Y directions when clamping the battery cell 200.

[0038] See also Figure 1 and Figure 2 ,in, Figure 1In order to show the structure more clearly, the clamp cylinder 400 and the mounting plate 110 are perspective wireframes. In the prior art, the tray 300 is provided with a plurality of grooves spaced apart along the X-axis direction and the Y-axis direction, and the battery cells 200 are placed in the grooves. The mounting plate 110 is extended along the Y-axis direction of the tray 300, and the clamp cylinder 400 is fixed on the mounting plate 110. The battery cells 200 are clamped by one clamp cylinder 400 corresponding to one battery cell 200. It can be understood that for different models of battery cells 200, the length and width of the battery cells 200 will also be different. Therefore, the prior art method of clamping the battery cells 200 one by one by the clamp cylinder 400 can adjust the distance between the two clamps on the clamp cylinder 400 by adjusting the stroke of the cylinder or the position of the two clamps, thereby being compatible with different length (X-direction) dimensions of the battery cells 200. However, because the spacing of the clamp cylinders 400 in the Y direction is designed according to the spacing of the battery cells 200 in the tray 300 and cannot be adjusted, if the width of the battery cells 200 (in the Y direction), or the spacing of the battery cells 200 in the Y direction of the tray 300, or the number of battery cells 200 arranged in the Y direction changes, the clamp cylinders 400 cannot align with the battery cells 200, resulting in the inability to clamp the battery cells 200. The only option is to replace the loading fixture. Therefore, the battery cell loading method in the prior art is not compatible with changes in the Y direction.

[0039] See also Figures 3 to 10 ,in, Figures 3 to 6 In order to show the structure more clearly, the mounting plate 110, the clamping assembly 120, the movable assembly 130 and the driving assembly 140 are all or partly perspective wireframes. In one embodiment of the utility model, a battery cell loading device 100 includes a mounting plate 110, the length of which extends along the Y-axis direction of the tray 300; and two clamping assemblies 120, which are arranged at intervals along the width direction of the mounting plate 110, and the clamping assembly 120 includes a fixed plate 121 and a plurality of clips 122, and the fixed plate 121 is movably arranged on the mounting plate 110; along the Y-axis direction of the tray 300, a plurality of clips 122 are arranged at intervals on the fixed plate 121, and a clamping space 122a is formed between the clips 122 arranged oppositely on the two clamping assemblies 120, and the two fixed plates 121 can move relatively along the X-axis direction of the tray 300, so that the clamping space 122a is adjusted to clamp the battery cell 200.

[0040] In the technical solution of the utility model, the battery cell loading device 100 includes a mounting plate 110 and two clamping assemblies 120. The length of the mounting plate 110 extends along the Y-axis direction of the tray 300. The two clamping assemblies 120 are spaced apart along the width direction of the mounting plate 110. The clamping assembly 120 includes a fixed plate 121 and a plurality of clips 122. The plurality of clips 122 are spaced apart along the Y-axis direction of the tray 300 on the fixed plate 121 so that the two clamping assemblies 120 form two rows of oppositely arranged clips 122. A clamping space 122a is formed between the two rows of clips 122. The clamping space 122a can be adjusted to clamp the battery cell 200. It can be understood that the present technical solution connects a whole row of clips 122 in the Y-axis direction through the fixing plate 121. When clamping the battery cells 200, the clips 122 in the same row can be closed or opened at the same time, so that when the spacing of the battery cells 200 in the tray 300 in the Y-axis direction changes and the number of battery cells 200 increases or decreases, the clips 122 can be directly compatible with clamping without the need to replace the fixture or change the type; at the same time, the clamping space 122a formed between the two rows of clips 122 can be adjusted, and when the length of the battery cells 200 in the X-direction changes, compatible adjustment in the X-axis direction can also be achieved.

[0041] In this embodiment, see Figure 3 Taking a tray 300 provided with 10 rows and 4 columns of battery cells 200 as an example, the tray 300 has an X direction and a Y direction. In the utility model, the mounting plate 110 is a rectangular plate body, which is extended along the Y-axis direction of the tray 300. The length of the mounting plate 110 is determined according to the size of the tray 300. The mounting plate 110 is movably connected to two clamping assemblies 120 on one side facing the tray 300. The two clamping assemblies 120 are arranged at intervals. Each clamping assembly 120 includes a fixed plate 121 and a plurality of clips 122. The outer side of the fixed plate 121 is provided with a plurality of clips 122. The plurality of clips 122 are arranged at intervals along the length direction of the mounting plate 110 (i.e., the Y direction of the tray 300). Preferably, the spacing between two adjacent clips 122 on the same fixed plate 121 is smaller than the width of the battery cell 200, so as to better accommodate the changes of the battery cell 200 in the Y direction. The side of the clip 122 that contacts the battery cell 200 matches the shape of the battery cell 200 to prevent the outer surface of the battery cell 200 from being damaged. Figure 4, two rows of clips 122 are arranged opposite to each other and form a clamping space 122a (as shown by the arrow in the figure), presenting an inverted "concave" shape, and the two rows of clips 122 are moved closer or farther away from each other through the movement of the two fixed plates 121 to adjust the size of the clamping space 122a in the X direction. It can be understood that by connecting a whole row of clips 122 arranged in the Y direction through the fixed plate 121, the clips 122 on the same side can achieve the action of closing or opening at the same time. When loading the battery cell 200, the battery cell loading device 100 approaches the battery cell 200 on the tray 300, and the clamping assembly 120 opens to allow the battery cell 200 to enter the clamping space 122a. Through the movable fixed plate 121, the two rows of clips 122 clamp the battery cell 200, and the battery cell 200 is clamped out by the robot or other transmission mechanism for the loading process. It should be noted that in addition to connecting multiple clips 122 together by providing a rectangular fixing plate 121, the clips 122 can also be connected in series by means of chains, ropes, buckles, etc., as long as the clips 122 on the same side can be opened and closed at the same time, the embodiments of the utility model are not limited to this, and the above are all within the protection scope of the utility model.

[0042] The following describes the clamping state of the clamping assembly 120 of the battery cell feeding device 100 of the utility model in different situations. It should be noted that the outer dimensions of the tray 300 in the following examples are consistent. Taking the clamping of battery cells A and B as an example, the width of battery cell B is smaller than that of battery cell A. There are two situations for the Y-direction arrangement of battery cells A and battery cells B on the tray 300, which are specifically determined according to the number of battery cells 200 arranged in the Y direction. Situations (I) and (II) are the clamping situations of battery cell A at different spacings, and situations (III) and (IV) are the clamping situations of battery cell B at different spacings.

[0043] (I) See Figure 7 , the battery cell A is clamped. At this time, there are 10 battery cells A arranged upwardly on the tray 300, and the state of the clamp 122 clamping the battery cell A is as shown in FIG. Figure 7 (ii) See Figure 8 , the battery cell A is clamped. At this time, 9 battery cells A are arranged in the Y direction of the tray 300. It can be understood that due to the reduction in the number of battery cells A, the spacing between adjacent battery cells A in the Y direction is greater than that in case (I). The state of the clip 122 clamping the battery cell A is as follows: Figure 8 (III) See Fig. 9 , the battery cell B is clamped. At this time, 18 battery cells B are arranged upwardly in the Y direction of the tray 300, and the state of the clamp 122 clamping the battery cell B is as shown in FIG. Fig. 9 (IV) See Fig.10, the battery cell B is clamped. At this time, there are 12 battery cells B arranged in the Y direction of the tray 300. It can be understood that due to the reduction in the number of battery cells B, the spacing between the adjacent battery cells B in the Y direction is greater than that in case (iii). The state of the clip 122 clamping the battery cell B is as follows: Fig.10 As shown in the above embodiments, it can be seen that no matter what width size the battery cell 200 has, or how the number or spacing of the battery cells 200 in the Y direction changes, the battery cell feeding device 100 of the present invention can be compatible and adjusted to achieve the adaptation of different types of battery cells 200 without changing the clamp.

[0044] See also Figures 3 to 6 Furthermore, in one embodiment of the utility model, the clip 122 includes a connecting portion 1221, a contact portion 1222, a guide member 1223 and an elastic member 1224, one end of the connecting portion 1221 is connected to the fixed plate 121, the contact portion 1222 is spaced apart at a side of the connecting portion 1221 facing the battery cell 200, the connecting portion 1221 and the contact portion 1222 are movably connected through the guide member 1223, the elastic member 1224 is disposed on the guide member 1223 and is located between the connecting portion 1221 and the contact portion 1222, and when the contact portion 1222 contacts the battery cell 200 and moves toward the connecting portion 1221, the elastic member 1224 is compressed.

[0045] Specifically, in this embodiment, the clip 122 includes a connecting portion 1221, a contact portion 1222, a guide member 1223 and an elastic member 1224. One end of the connecting portion 1221 is detachably connected to the outer edge of the fixed plate 121. The connecting portion 1221 is arranged at 90° to the fixed plate 121. The inner end surface of the connecting portion 1221 is spaced apart with a contact portion 1222. The contact portion 1222 is used to contact the outer shell of the battery cell 200. The contact portion 1222 can be movably connected to the connecting portion 1221 through the guide member 1223. Furthermore, the guide member 1223 is preferably a guide pin, the elastic member 1224 is preferably a spring, a through hole is provided on the connecting portion 1221, one end of the guide pin is a brim structure and is placed on the through hole to prevent the guide pin from falling out of the contact portion 1222, and the other end passes through the through hole and is locked into the contact portion 1222 to connect the connecting portion 1221 and the contact portion 1222, the spring is sleeved on the guide pin, and when the clamping action is performed, the contact portion 1222 contacts the battery cell 200, and due to the effect of the force, the battery cell 200 will cause the contact portion 1222 to contact the battery cell 200. The contact portion 1222 approaches the connecting portion 1221 and compresses the spring. With such arrangement, on the one hand, since there is a certain interval between the contact portion 1222 and the connecting portion 1221 and they are movably connected through the guide pin, and a spring is sleeved on the guide pin to provide elastic force, different length errors of the battery cell 200 can be absorbed when clamping the battery cell 200; on the other hand, when clamping, the elastic action of the elastic member 1224 will push back the contact portion 1222, so that the two rows of clips 122 can clamp the battery cell 200 more tightly.

[0046] See also Figure 5 Furthermore, in one embodiment of the utility model, a side of the contact portion 1222 facing the battery cell 200 is provided with an anti-slip portion 1225, and the anti-slip portion 1225 is used to contact the battery cell 200. Specifically, in this embodiment, the side of the contact portion 1222 facing the battery cell 200 is set as a rubber-coated surface, that is, the anti-slip portion 1225 is a layer of soft material wrapped on the surface of the contact portion 1222, and materials such as TPE, PU, ​​and silicone can be used. By setting the clip 122 to have a rubber-coated surface, on the one hand, the friction of the clip 122 can be increased, while saving the thickness space of the clip 122, so as to facilitate compatibility with smaller battery cell 200 spacing; on the other hand, since the rubber-coated surface is made of flexible material, it can prevent the clip 122 from scratching the surface of the battery cell 200 when clamping the battery cell 200.

[0047] See also Figures 3 to 6 Furthermore, in one embodiment of the utility model, a movable component 130 is included, and the movable component 130 is connected to the mounting plate 110 and the fixed plate 121 respectively, and the fixed plate 121 moves along the X-axis direction of the tray 300 on the mounting plate 110 through the movable component 130.

[0048] Specifically, in this embodiment, a movable component 130 is arranged between the mounting plate 110 and the clamping component 120, and the clamping component 120 moves along the X direction of the pallet 300 on the mounting plate 110 through the movable component 130; the movable component 130 has a basic part and a moving part, the basic part is fixed on the mounting plate 110, the moving part moves on the basic part, the moving part is connected to the fixed plate 121 of the clamping component 120, and the fixed plate 121 moves back and forth on the basic part along the X direction of the pallet 300 through the moving part. It can be understood that if the clamping assembly 120 directly reciprocates on the mounting plate 110, for example, a sliding groove is opened on the mounting plate 110, a bolt is used to pass through the sliding groove and connect the clamping assembly 120, and the rod of the bolt moves in the sliding groove to realize the clamping action of the clamp 122. In this way of movement, due to the large contact area between the mounting plate 110 and the fixed plate 121, the friction generated during the movement will be very large, which makes the clamping assembly 120 difficult to push and the workpiece is also prone to wear; therefore, by arranging the movable assembly 130 between the mounting plate 110 and the clamping assembly 120, on the one hand, the friction generated during the movement between the clamping assembly 120 and the mounting plate 110 can be reduced, so that the clamping action is faster and the work efficiency is improved. At the same time, the movable assembly 130 can provide a guiding effect, so that the clamping assembly 120 is more accurate and stable when clamping the battery cell 200; on the other hand, the modularly designed movable assembly 130 can realize rapid replacement and upgrading of components, and can be easily combined with the automatic control system to improve the flexibility and market adaptability of the device.

[0049] See also Figures 3 to 6 Furthermore, in one embodiment of the utility model, the movable component 130 includes a slide rail 131 and two sliders 132; the slide rail 131 is arranged on the mounting plate 110, and the slide rail 131 extends along the X-axis direction of the tray 300, and the two sliders 132 are respectively arranged at both ends of the slide rail 131, and the fixed plate 121 is arranged on the slider 132, and the two fixed plates 121 are relatively movable on the slide rail 131 along the X-axis direction of the tray 300 through the slider 132.

[0050] Specifically, in this embodiment, the movable assembly 130 is preferably a sliding pair, including a slide rail 131 and two sliders 132. The slide rail 131 is fixed on the mounting plate 110 and extends along the X direction of the tray 300. The two sliders 132 can slide on the slide rail 131. The two sliders 132 are respectively connected to the fixed plates 121 of the two clamping assemblies 120. The fixed plates 121 reciprocate along the X direction of the tray 300 on the slide rail 131 through the sliders 132 to drive the two rows of clips 122 to achieve opening and closing. It can be understood that since the size of the tray 300 in the Y direction is usually longer, six sliding pairs are arranged at intervals on the mounting plate 110 to better guide the movement of the two rows of clips 122; in addition, more than two sliders 132 can also be arranged on the slide rail 131, for example, four sliders 132 are arranged, and each fixed plate 121 is connected to two sliders 132. As long as the two fixed plates 121 can achieve reciprocating movement on the slide rail 131, it is not limited here. By connecting the mounting plate 110 and the clamping assembly 120 in the form of a slide rail 131 and a slider 132, the clamping assembly 120 can be provided with precise guiding and positioning functions, ensuring the accuracy and stability of the clamp 122 during operation. At the same time, the slider 132 can significantly reduce the friction during the clamping activity and absorb the vibration and impact generated during the activity, thereby reducing energy consumption and wear and extending the service life of the clamp 122. Of course, in some other embodiments, the movable assembly 130 can also adopt other forms, such as a crank slider mechanism, a gear rack mechanism, etc., and the embodiments of the utility model are not limited thereto, and the above are all within the protection scope of the utility model.

[0051] See also Figures 3 to 6Furthermore, in one embodiment of the utility model, a driving assembly 140 is included, the driving assembly 140 is connected to the fixing plate 121, and the driving assembly 140 drives the two fixing plates 121 to move relative to each other along the X-axis direction of the tray 300, so that the clamping space 122a is adjusted to clamp the battery cell 200. Specifically, in this embodiment, the battery cell loading device 100 is further provided with a driving assembly 140 to realize automatic control of the clamping assembly 120, the driving assembly 140 is connected to the fixing plate 121, and the driving assembly 140 adjusts the size of the clamping space 122a by driving the fixing plate 121 to move, thereby automatically completing the clamping work of the battery cell 200. It should be noted that the drive component 140 is a single power, replacing the multi-power solution of using multiple groups of clamps 122 cylinders in the prior art, so that the battery cell loading device 100 of the present application can be adjusted at the same time when the power is single, and when the length specification of the battery cell 200 in the X direction changes, the drive component 140 can automatically adjust different positions to achieve compatibility.

[0052] See also Figures 3 to 6 Furthermore, in one embodiment of the utility model, the driving assembly 140 includes a motor 141, a forward and reverse screw rod 142 and two adapter plates 143. The forward and reverse screw rod 142 is connected to the output end of the motor 141. The two adapter plates 143 are respectively arranged at the two ends of the forward and reverse screw rod 142. The adapter plate 143 is connected to the fixed plate 121. When the motor 141 rotates, the screw rod drives the two adapter plates 143 to reciprocate, so that the two fixed plates 121 move relative to each other along the X-axis direction of the tray 300, so that the clamping space 122a is adjusted to clamp the battery cell 200.

[0053] Specifically, in this embodiment, the drive assembly 140 includes a motor 141, a forward and reverse screw rod 142 and two adapter plates 143. The motor 141 is a 750W servo motor, and the motor 141 is fixed on the motor 141 fixing plate 121; the two ends of the forward and reverse screw rod 142 are respectively fixed on the mounting plate 110 through bearing seats. The forward and reverse screw rod 142 is a double-rotation design, one end is a left-handed screw thread, and the other end is a right-handed screw thread, which can realize the conversion between spiral and linear motion in two directions. Due to the structural characteristics of the forward and reverse screw rod 142, it can replace two unidirectional screw rods to save installation space. An adapter plate 143 is provided at both ends of the forward and reverse screw rods 142, and one end of the adapter plate 143 away from the forward and reverse screw rods 142 is connected to the clamping assembly 120, and one end of the forward and reverse screw rods 142 is connected to the output end of the motor 141 through a coupling. The adapter plate 143 drives the fixed plate 121 to reciprocate through the forward and reverse rotation of the motor 141, so as to realize the opening or closing of the two rows of clips 122 at the same time. In this embodiment, a combination of a servo motor and a forward and reverse screw rod 142 is preferably used. The servo motor can accurately control the position of the adapter plate 143 on the forward and reverse screw rods 142. Through the control of the servo motor, the initial size of the clamping space 122a and the size in the clamping state can be freely adjusted to adapt to the specifications of the battery cells 200 with different lengths in the X direction.

[0054] See also Figures 3 to 6 Furthermore, in an embodiment of the present invention, the distance between two adjacent clips 122 on the fixing plate 121 is 2 mm to 5 mm. Specifically, in this embodiment, the distance between two adjacent clips 122 on the fixing plate 121 is preferably 5 mm. It can be understood that when the distance between two adjacent clips 122 on the same side is smaller, the clamping compatibility of the battery cell 200 is better; Figures 7 to 10 It can be seen that no matter how the number of battery cells 200 in the Y direction or the spacing between the battery cells 200 changes, the two rows of clips 122 can be compatible. At the same time, when the spacing between the clips 122 is small, the clamping force can be more evenly distributed on the object, reducing the risk of damage to the object.

[0055] A second aspect of the present application provides a battery cell loading mechanism, comprising a battery cell 200 , a tray 300 and the above-mentioned battery cell loading device 100 ; the tray 300 is provided with a plurality of grooves spaced along the X-axis and the Y-axis, the grooves are used to place the battery cell 200 , and the battery cell loading device 100 is used to clamp the battery cell 200 .

[0056] Specifically, in this embodiment, the tray 300 has 10 rows and 4 columns of grooves for placing the battery cells 200. The number of battery cells 200 is multiple and placed in the grooves. When the battery cell loading device 100 is used to load the battery cells 200, the battery cells 200 are first fed through the material frame, and the battery cell loading device 100 is driven by a six-axis robot or other transmission mechanism to clamp the battery cells 200 in the order of the columns. After the clamping assembly 120 clamps and grasps a whole column of battery cells 200, the six-axis robot drives the battery cell loading device 100 to take out the battery cells 200 and place them on the transfer platform or other designated positions, completing the loading process of the battery cells 200. Of course, it is also possible to set up sensors, cameras or other visual detection devices to scan and locate the battery cells 200 on the tray 300 before clamping the battery cells 200, so as to achieve more accurate battery cell 200 loading, wherein the visual detection device is preferably a visual positioning camera and a rangefinder. Furthermore, a row of anti-drop bottom gripping claws are respectively provided on both sides of the battery cell 200 loading device to prevent the battery cells 200 from slipping and falling. The beneficial effects of the battery cell loading device 100 of the present application are equivalent to the beneficial effects of the above-mentioned battery cell loading device 100, which will not be repeated here.

The battery production equipment of this embodiment also includes a conveying mechanism, a welding mechanism, a winding mechanism, etc., each of which is used in a different process to achieve battery production. The beneficial effects of the battery production equipment of the present application are equivalent to the beneficial effects of the above-mentioned battery cell feeding device 100, which will not be repeated here.

[0058] The above description is only an optional embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
