[0003] The clamps in the related art have poor compatibility when in use and are inconvenient for clamping battery cells of different sizes and spacings, which brings inconvenience to work. Utility Model Content

[0004] In view of the above problems, the present application provides a clamping device and a battery cell flipping production line, which can solve the problem that the existing clamps have poor compatibility and are inconvenient to clamp battery cells of different sizes and spacings when in use.

[0005] To solve the above technical problems, in a first aspect, the present application proposes a clamping device, comprising:

[0006] Bracket;

[0007] a first movable plate, wherein the first movable plate is provided with an inclined slot;

[0008] at least two grippers, each gripper being slidably connected to the bracket, and one end of each gripper being located in the chute;

[0009] a first driving member, the first driving member being fixed to the bracket and connected to the first movable plate, and being configured to drive the first movable plate to move along a first direction;

[0010] Under the condition that the first movable plate moves along the first direction, one end of the gripper moves relative to the inclined slot along the extension direction of the inclined slot, and the gripper can move relative to the bracket along the second direction, wherein the first direction is the extension and retraction direction of the first driving member, and the second direction intersects with the first direction.

[0011] In the technical solution of the embodiment of the present application, when the first driving member drives the first movable plate to move along the first direction, the gripper moves along the inclined groove and the second direction at the same time. At this time, under the limitation of the inclined groove, the two adjacent grippers will be separated in the second direction, thereby realizing the adjustment of the gripper spacing. In this way, battery cells of different sizes and spacings can be clamped, with strong compatibility and effectively improved production efficiency.

[0012] In some embodiments, the gripping device further comprises a cam follower, the cam follower being disposed on the gripper and located in the inclined slot, so that when the first movable plate moves along the first direction, the cam follower will synchronously slide in the inclined slot.

[0013] In some embodiments, the bracket is provided with at least two first slide rails and at least one second slide rail, the first slide rails extend along the first direction, and the second slide rails extend along the second direction;

[0014] The first movable plate is slidably connected to the two first slide rails at two sides along the second direction, and the gripper is slidably connected to the second slide rail at one end facing the bracket.

[0015] In some embodiments, the gripper includes a first clamping arm, a second clamping arm, a second driving member, and a connecting plate;

[0016] The second driving member is disposed on the connecting plate, and the second driving member is connected to the first clamping arm and the second clamping arm respectively;

[0017] The cam follower is fixed to the connecting plate, and the connecting plate is slidably connected to the second slide rail. In this way, the first clamping arm and the second clamping arm are driven to move by the second driving member to clamp the battery cell.

[0018] In some embodiments, the gripping device further comprises a first detection member, which is disposed on the bracket and is used to detect the distance between two adjacent grippers along the second direction, thereby facilitating detection of the distance between the two grippers.

[0019] In some embodiments, the gripping device further includes a bottom support assembly, which is disposed on the bracket and positioned on the bottom surface of the battery cell when the gripper grasps the battery cell. Thus, when the gripper grasps the battery cell, the bottom support assembly supports the bottom surface of the battery cell, thereby preventing the battery cell from falling.

[0020] In some embodiments, the bottom support assembly includes a bottom support rod and at least two support plates;

[0021] The two support plates are respectively disposed on either side of the bracket along the second direction, and the bottom support rod is disposed between the two support plates. The bottom support rod is movable relative to the support plates in a first direction and a third direction, wherein the third direction is perpendicular to a plane formed by the first and second directions. Thus, before grabbing a battery cell, the position of the bottom support rod in the first and third directions is adjusted so that the bottom support rod is away from the battery cell; after grabbing the battery cell, the position of the bottom support rod in the first and third directions is adjusted so that the bottom support rod is located on the bottom surface of the battery cell, thereby preventing the battery cell from falling.

[0022] In some embodiments, the bottom support assembly further includes a third driving member, a second movable plate, and a fourth driving member;

[0023] The third driving member, the second movable plate and the fourth driving member are provided on opposite sides of the two support plates; the third driving member is connected to the second movable plate, and is used to drive the second movable plate to move along the third direction; the fourth driving member is connected to the second movable plate, and is used to drive the second movable plate to move along the first direction;

[0024] The two ends of the bottom support rod are connected to the two second movable plates respectively. In this way, the second movable plates are driven to move in the first direction and the third direction by the third driving member and the fourth driving member, which can conveniently drive the bottom support rod to move in the first direction and the third direction.

[0025] In some embodiments, the bottom support assembly further includes a third slide rail and a fourth slide rail, the third slide rail extends along the third direction, and the fourth slide rail extends along the first direction;

[0026] The third slide rail is provided on opposite sides of the two support plates, the second movable plate is slidably connected to the third slide rail, the fourth slide rail is provided on the second movable plate, and the fourth driving member is connected to the fourth slide rail for driving the fourth slide rail to move along the first direction;

[0027] The ends of the bottom-protecting rod are connected to the fourth slide rails on the two second movable plates. In this way, the second movable plates are driven to move relative to the third slide rails by the third driving member, and the fourth slide rails are driven to move in the first direction by the fourth driving member, thereby driving the bottom-protecting rod to move in the first and third directions.

[0028] In some embodiments, the bottom support assembly further includes a fifth driving member and a pressure rod, and the pressure rod extends along the second direction;

[0029] The fifth driving member is disposed on the second movable plate and is connected to the pressure rod to drive the pressure rod to move in the first direction. In this way, when the gripper grabs the battery cell, the fifth driving member drives the pressure rod to press the tray, thereby preventing the tray from being lifted up after the battery cell is grabbed.

[0030] In some embodiments, the bottom support assembly further includes a second detection member, which is disposed on the bottom support rod and is used to detect the position of the bottom support rod. This facilitates detection of the position of the bottom support rod and prevents the bottom support rod from colliding with the battery cell and causing damage to the battery cell.

[0031] In some embodiments, the gripping device further comprises a tray gripping assembly, which is disposed on opposite sides of the two support plates. This allows the tray gripping assembly to be integrated with the cell gripper, allowing the entire device to grip not only the cells but also the tray, effectively reducing the overall device cost and footprint.

[0032] In some embodiments, the tray gripping assembly includes a sixth driving member and a moving block;

[0033] The sixth driving member is provided on the support plate and is connected to the moving block to drive the moving block to move along the first direction. In this way, the tray can be conveniently clamped by driving the moving block to move along the first direction through the sixth driving member.

[0034] In some embodiments, the tray clamping assembly further comprises a connecting post, an insert rod, and a clamping plate, wherein the connecting post is capable of extending and retracting along the first direction;

[0035] The connecting post and the insertion rod are both located on the side of the moving block facing away from the sixth drive member. The end of the connecting post away from the moving block is connected to the clamping plate, and the end of the insertion rod away from the moving block can pass through the clamping plate. In this way, when the clamping plate clamps the pallet, the clamping plate compresses the connecting post and retracts it, allowing the insertion rod to pass through the clamping plate and be inserted into the pallet, effectively preventing the pallet from falling.

[0036] In some embodiments, the clamping plate is provided with a guide hole, and the end of the insertion rod away from the moving block is a pointed structure, and the end of the insertion rod away from the moving block can pass through the guide hole, so as to facilitate the insertion of the insertion rod into the tray.

[0037] In some embodiments, the tray clamping assembly further comprises an elastic member disposed between the moving block and the clamping plate, so that when the pressure acting on the clamping plate disappears, the elastic member can drive the clamping plate to return to its initial state.

[0038] In some embodiments, the tray clamping assembly further includes a third detecting member, which is disposed on the sixth driving member and is used to detect the position of the sixth driving member. This facilitates detection of the position of the sixth driving member.

[0039] In some embodiments, the clamping device further includes a fourth detection member, which is disposed on the bracket and is used to detect the position of the tray. This makes it easier to detect the position of the tray.

[0040] In some embodiments, the clamping device further comprises a light source, and the light source is disposed on the fourth detection member. In this way, the light source can provide illumination to the fourth detection member, which is beneficial for photographing the fourth detection member.

[0041] In some embodiments, the clamping device further comprises a fixing member disposed on the bracket and detachably connected to the first movable plate. In this way, when the device malfunctions, the fixing member can be used to fix the first movable plate, thereby preventing the first movable plate from falling off during maintenance.

[0042] In some embodiments, the fixing member includes a fixing seat and a pin shaft, and the first movable plate is provided with a shaft hole;

[0043] The fixing seat is arranged on the bracket, one end of the pin is movably connected to the fixing seat, and the other end passes through the shaft hole. In this way, the first movable plate can be conveniently fixed by inserting the pin into the corresponding shaft hole.

[0044] In some embodiments, the clamping device further comprises a flange, which is disposed on the bracket, so that the entire device can be easily connected to other components via the flange.

[0045] In a second aspect, the present application proposes a battery cell repackaging production line, comprising a clamping device as described in any one of the embodiments of the present application.

[0081] Currently, market developments indicate that the application of power lithium batteries is becoming increasingly widespread. Power lithium batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As the application of power lithium batteries continues to expand, market demand is also growing.

[0082] When power lithium batteries are shipped to customers, the packaging for each customer may differ from our own cell packaging. Therefore, we need to remove the cells from our own cell packaging and place them in the customer's packaging. This process of transferring cells from our own packaging to various customer packaging boxes is called cell repackaging.

[0083] In the battery cell repacking production line, a clamp is required to grip the battery cells. However, the clamps in the related art have poor compatibility and are not convenient for gripping battery cells of different sizes and spacings, which brings inconvenience to the work.

[0084] Based on the above considerations, in order to solve the problem that the clamp has poor compatibility and is inconvenient to clamp battery cells of different sizes and spacings when in use, a clamping device is designed, which includes a bracket, a first movable plate, a first driving member and at least two grippers, wherein an inclined groove is provided on the first movable plate, the gripper is slidably connected to the bracket, and one end of the gripper is located in the inclined groove, the first driving member is fixed to the bracket, and the first driving member is connected to the first movable plate, for driving the first movable plate to move along the first direction; under the condition that the first movable plate moves along the first direction, one end of the gripper moves relative to the inclined groove along the extension direction of the inclined groove, and the gripper can move relative to the bracket along the second direction, wherein the first direction is the telescopic direction of the first driving member, and the second direction intersects with the first direction.

[0085] During use, when the first driving member drives the first movable plate to move along the first direction, the gripper moves along the inclined groove and the second direction at the same time. At this time, under the limitation of the inclined groove, the two adjacent grippers will be separated in the second direction, thereby realizing the adjustment of the gripper spacing. In this way, battery cells of different sizes and spacings can be clamped, with strong compatibility and effectively improved production efficiency.

[0086] According to some embodiments of the present application, Figure 1 This is a schematic diagram of the structure of the clamping device in this application. Figure 2 This is a schematic structural diagram of the back of the clamping device in this application. Figure 3 Schematic diagram of the internal structure of the clamping device in this application. Figure 1-3 As shown, the present application provides a clamping device, which includes a bracket 10, a first movable plate 12, a first driving member 11 and at least two grippers 13, wherein the first movable plate 12 is provided with an inclined groove 121, the gripper 13 is slidably connected to the bracket 10, and one end of the gripper 13 is located in the inclined groove 121, the first driving member 11 is fixed to the bracket 10, and the first driving member 11 is connected to the first movable plate 12, and is used to drive the first movable plate 12 to move along a first direction. When the first movable plate 12 moves along the first direction, one end of the gripper 13 moves relative to the inclined groove 121 along the extension direction of the inclined groove 121, and the gripper 13 can move relative to the bracket 10 in a second direction, wherein the first direction is the extension and contraction direction of the first driving member 11, and the second direction intersects with the first direction.

[0087] In this embodiment, the first driving member 11 may include a motor 111 and a variable pitch ball screw 112, wherein the output shaft of the motor 111 is connected to the variable pitch ball screw 112, and the variable pitch ball screw 112 is connected to the gripper 13. Of course, it is understood that the first driving member 11 may also be other structures, such as an electric telescopic rod, a hydraulic rod, etc. The specific structure can be determined according to actual conditions and is not limited in this embodiment of the present invention.

[0088] The number of grippers 13 in this embodiment can be two, three, five, etc., which can be determined according to actual conditions and is not limited in this embodiment of the present specification.

[0089] In this embodiment, if Figure 1 As shown, the first direction is the Y-axis direction, and the second direction is the X-axis direction, wherein the angle between the X-axis and the Y-axis can be 80°, 85°, 90°, etc. This embodiment is described by taking the X-axis and the Y-axis as perpendicular to each other as an example.

[0090] In this embodiment, a plurality of inclined grooves 121 are provided on the first movable plate 12 , and the specific number can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0091] In this embodiment, the extending direction of the inclined groove 121 is arranged at an angle with the Y-axis direction, and the angle is greater than 0° and less than 90°.

[0092] In this embodiment, the first driving member 11 includes a motor 111 and a variable pitch ball screw 112, wherein the motor 111 can be fixed to the bracket 10 by bolts, the output shaft of the motor 111 is connected to the variable pitch ball screw 112, the variable pitch ball screw 112 is arranged along the Y-axis direction, and the variable pitch ball screw 112 and the first movable plate 12 can be connected by bolts.

[0093] The first movable plate 12 is slidably connected to the bracket 10 at both sides along the X-axis direction, and the first movable plate 12 can move relative to the bracket 10 along the Y-axis direction.

[0094] One end of the gripper 13 facing the first movable plate 12 is slidably connected to the bracket 10 , and the gripper 13 can move relative to the bracket 10 along the X-axis direction.

[0095] During use, since when the first movable plate 12 moves along the Y-axis direction, one end of the gripper 13 can move relative to the inclined groove 121 along the extension direction of the inclined groove 121, and the gripper 13 can move relative to the bracket 10 along the X-axis, in this way, when the first driving member 11 drives the first movable plate 12 to move along the Y-axis direction, the gripper 13 moves along the inclined groove 121 and the X-axis at the same time. At this time, under the limitation of the inclined groove 121, the two adjacent grippers 13 will be separated in the X-axis direction, thereby realizing the adjustment of the spacing between the grippers 13.

[0096] In the technical solution of the embodiment of the present application, when the first driving member 11 drives the first movable plate 12 to move along the first direction, the gripper 13 moves along the inclined groove 121 and the second direction at the same time. At this time, under the limitation of the inclined groove 121, the two adjacent grippers 13 will be separated in the second direction, thereby realizing the adjustment of the spacing between the grippers 13. In this way, battery cells of different sizes and spacings can be clamped, which has strong compatibility and effectively improves production efficiency.

[0097] According to some embodiments of the present application, Figure 3 or Figure 4 As shown, the clamping device further includes a cam follower 14 , which is disposed on the gripper 13 and is located in the inclined slot 121 .

[0098] Since the cam follower 14 can slide synchronously relative to the inclined slot 121 , when the first movable plate 12 moves along the Y-axis direction, the cam follower 14 will slide synchronously in the inclined slot 121 , thereby separating the gripper 13 along the X-axis direction.

[0099] Of course, it is understandable that the gripper 13 may also cooperate with the inclined groove 121 through a roller shaft. The specific details may be determined according to actual conditions, and the embodiments of this specification do not limit this.

[0100] According to some embodiments of the present application, Figure 3 Combined with Figure 5 As shown, at least two first slide rails 101 and at least one second slide rail 102 are provided on the bracket 10, the first slide rails 101 extend along the first direction, and the second slide rails 102 extend along the second direction; wherein, the first movable plate 12 is slidably connected to the two first slide rails 101 on both sides along the second direction, and the gripper 13 is slidably connected to the second slide rail 102 toward one end of the bracket 10.

[0101] In this embodiment, one first slide rail 101 may be provided on both sides of the bracket 10 along the X-axis direction, or two first slide rails 101 may be provided on both sides of the bracket 10 along the X-axis direction. The specific arrangement may be determined based on actual conditions and is not limited in this specification.

The specific details can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0104] refer to Figure 5As shown, in this embodiment, a slider 135 is provided on the gripper 13 , and the slider 135 is slidably connected to the second slide rail 102 .

[0105] In this embodiment, sliders (not marked in the figure) are also provided on both sides of the first movable plate 12 along the X-axis direction. The sliders are slidably connected to the first slide rail 101 .

[0106] In this embodiment, since the first slide rail 101 and the second slide rail 102 are provided on the bracket 10, it is convenient for the first movable plate 12 to be slidably connected to the bracket 10 in the Y-axis direction, and at the same time, it is convenient for the gripper 13 to be slidably connected to the bracket 10 in the X-axis direction.

[0107] According to some embodiments of the present application, Figure 4 As shown, the gripper 13 includes a first clamping arm 131, a second clamping arm 132, a second driving member 133 and a connecting plate 134; wherein, the second driving member 133 is arranged on the connecting plate 134, and the second driving member 133 is respectively connected to the first clamping arm 131 and the second clamping arm 132; the cam follower 14 is fixed to the connecting plate 134, and the connecting plate 134 is slidably connected to the second slide rail 102.

[0109] In this embodiment, the connecting plate 134 can be connected to the second driving member 133 by bolts, and the cam follower 14 can be clamped on the connecting plate 134. The specific method can be determined according to actual conditions and is not limited in this embodiment of the present specification.

[0110] In this embodiment, the telescopic end of the second driving member 133 can be connected to the first clamping arm 131 and the second clamping arm 132 respectively through bolts. When in use, the second driving member 133 drives the first clamping arm 131 and the second clamping arm 132 to approach each other to clamp the battery cell.

[0111] It should be noted that the above-mentioned gripper structure is only an example. In other alternative solutions, other structures may also be adopted, for example, the gripper may be an existing mechanical claw, a hydraulic gripper, etc. This application does not impose any special restrictions on the specific structure of the gripper, as long as the above-mentioned structure can achieve the purpose of this application.

[0112] According to some embodiments of the present application, Figure 1 or Figure 3 As shown, the clamping device further includes a first detecting member 17 , which is disposed on the bracket 10 and is used to detect the distance between two adjacent grippers 13 along the second direction.

[0113] The first detection element 17 in this embodiment can be a distance measuring sensor, an infrared sensor, etc., and the specific one can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0114] In this embodiment, a connecting rod 18 is connected to the bracket 10 by bolts, and the first detecting member 17 is fixed to the connecting rod 18 by bolts, and the position of the first detecting member 17 corresponds to the position of the gripper 13 .

[0115] During use, when the two grippers 13 are driven by the first movable plate 12, the two grippers 13 will separate along the X-axis direction. At this time, the first detection member 17 detects the distance between the two grippers 13 along the X-direction. When the distance between the two grippers 13 along the X-direction reaches the requirement, the first movable plate 12 stops moving.

[0116] According to some embodiments of the present application, Figure 1 Combined with Figure 6 As shown, the clamping device further includes a bottom support component 15 , which is disposed on the bracket 10 . When the gripper 13 grips the battery cell, the bottom support component 15 is located on the bottom surface of the battery cell.

[0117] The bottom support assembly 15 in this embodiment can be fixed to the bracket 10 by means of bolts. The specific amount can be determined according to actual conditions and is not limited in this embodiment of the present specification.

[0118] During use, when the gripper 13 grabs the battery cell, the bottom support assembly 15 is supported on the bottom surface of the battery cell, which can prevent the battery cell from falling.

[0119] According to some embodiments of the present application, Figure 6 Combined with Figure 7 As shown, the bottom support assembly 15 includes a bottom support rod 157 and at least two support plates 151, wherein the two support plates 151 are respectively arranged on both sides of the bracket 10 along the second direction, the bottom support rod 157 is arranged between the two support plates 151, and the bottom support rod 157 can move relative to the support plate 151 along the first direction and the third direction, wherein the third direction is perpendicular to the plane formed by the first direction and the second direction.

[0120] The third direction in this embodiment is as follows Figure 6 The Z-axis direction is perpendicular to the plane formed by the X-axis and the Y-axis.

[0122] The bottom support rods 157 in this embodiment can be one, two, five, etc., and the specific number can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0123] Since the bottom rod 157 can move along the Y-axis and the Z-axis relative to the support plate 151, before grabbing the battery cell, the bottom rod 157 is adjusted to move on the Y-axis and the Z-axis so that the bottom rod 157 is away from the battery cell; after grabbing the battery cell, the bottom rod 157 is adjusted to move on the Y-axis and the Z-axis so that the bottom rod 157 is located at the bottom surface of the battery cell. In this way, under the support of the bottom rod 157, the battery cell can be prevented from falling from the gripper 13.

[0124] According to some embodiments of the present application, Figure 6 Combined with Figure 8 As shown, the bottom support assembly 15 also includes a third driving member 153, a second movable plate 154 and a fourth driving member 155, wherein the third driving member 153, the second movable plate 154 and the fourth driving member 155 are provided on the opposite side of the two support plates 151; the third driving member 153 is connected to the second movable plate 154, and is used to drive the second movable plate 154 to move along the third direction, and the fourth driving member 155 is connected to the second movable plate 154, and is used to drive the second movable plate 154 to move along the first direction; the two ends of the bottom support rod 157 are correspondingly connected to the two second movable plates 154.

[0125] In this embodiment, if Figure 8 and Figure 9 As shown, the second movable plate 154 is threadedly connected to the opposite sides of the two support plates 151 .

[0126] The third driving member 153 and the fourth driving member 155 in this embodiment can both be cylinders, electric telescopic rods, etc., and the specific ones can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0127] In this embodiment, the third driving member 153 can be fixed to the support plate 151, with the telescopic end of the third driving member 153 aligned with the support plate 151, while the fourth driving member 155 is fixed to the second movable plate 154. Alternatively, the fourth driving member 155 can be fixed to the support plate 151, with the telescopic end of the fourth driving member 155 aligned with the support plate 151, while the third driving member 153 is fixed to the second movable plate 154.

[0128] Both ends of the bottom support rod 157 in this embodiment are connected to the corresponding two second movable plates 154 through bolts.

[0129] When in use, the third driving member 153 and the fourth driving member 155 drive the second movable plate 154 to move in the Y-axis and Z-axis directions, thereby synchronously driving the bottom support rod 157 to move in the Y-axis and Z-axis directions.

[0130] According to some embodiments of the present application, Figure 8 Combined with Figure 9 As shown, the bottom support assembly 15 also includes a third slide rail 152 and a fourth slide rail 156, wherein the third slide rail 152 extends along the third direction and the fourth slide rail 156 extends along the first direction; the third slide rail 152 is provided on the opposite side of the two support plates 151, the second movable plate 154 is slidingly connected to the third slide rail 152, the fourth slide rail 156 is provided on the second movable plate 154, and the fourth driving member 155 is connected to the fourth slide rail 156 for driving the fourth slide rail 156 to move along the first direction; the two ends of the bottom support rod 157 are correspondingly connected to the fourth slide rails 156 on the two second movable plates 154.

[0131] In this embodiment, a third slide rail 152 is connected to the support plate 151 along the Z-axis direction by bolts. The number of the third slide rail 152 can be one, two, etc., and the specific number can be determined according to actual conditions. This embodiment of the present specification does not limit this.

[0132] In this embodiment, the third slide rail 152 extends along the Z-axis direction, and the fourth slide rail 156 extends along the Y-axis direction.

[0133] A first slide groove 1541 is fixed to the side of the second movable plate 154 facing the support plate 151, and the first slide groove 1541 is slidably connected to the third slide rail 152. The third driving member 153 is connected to the second movable plate 154 to drive the second movable plate 154 to move relative to the third slide rail 152 along the Z-axis direction.

[0134] A second slide groove 1542 is fixed on the side of the second movable plate 154 facing away from the support plate 151, the fourth driving member 155 is fixed to the second movable plate 154, and the telescopic end of the fourth driving member 155 is connected to the fourth slide rail 156. At the same time, the fourth slide rail 156 is slidably connected to the second slide groove 1542.

[0135] During use, the second movable plate 154 is driven to move relative to the third slide rail 152 along the Z-axis direction by the third driving member 153, and then the fourth slide rail 156 is driven to move along the Y-axis direction by the fourth driving member 155. Since the two ends of the bottom rod 157 are connected to the fourth slide rails 156 on the two second movable plates 154, the bottom rod 157 can be easily driven to move in the Y-axis direction and the Z-axis direction, so that the bottom rod 157 can be kept away from the battery cell or located at the bottom of the battery cell.

[0136] According to some embodiments of the present application, Figure 9As shown, the bottom cover assembly 15 also includes a fifth driving member 159 and a pressure rod 1591, wherein the pressure rod 1591 extends along the second direction; the fifth driving member 159 is arranged on the second movable plate 154, and the fifth driving member 159 is connected to the pressure rod 1591, for driving the pressure rod 1591 to move along the first direction.

[0137] The fifth driving member 159 in this embodiment can be a cylinder, an electric telescopic rod, etc. The specific one can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0138] In this embodiment, the fifth driving member 159 is fixed to the second movable plate 154 by bolts, and the telescopic end of the fifth driving member 159 is connected to the pressure rod 1591 by bolts. The fifth driving member 159 can drive the pressure rod 1591 to move along the Y-axis direction.

[0139] During use, after the gripper 13 grabs the battery cell, the fifth driving member 159 drives the pressing rod 1591 to move downward along the Y-axis, so that the pressing rod 1591 presses the battery cell tray, thereby preventing the battery cell tray from being lifted up after grabbing the battery cell.

[0140] According to some embodiments of the present application, Figure 6 As shown, the bottom support assembly further includes a second detection member 158 , which is disposed on the bottom support rod 157 and is used to detect the position of the bottom support rod 157 .

[0141] The second detection component 158 ​​in this embodiment can be a position sensor, an infrared sensor, etc., and the specific one can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0142] In this embodiment, the second detection member 158 can be fixed to the bottom rod 157 by bolts, or the second detection member 158 can be clamped on the bottom rod 157. The specific method can be determined according to actual conditions and is not limited in this embodiment of the present specification.

[0143] Since the second detection member 158 is provided on the bottom support rod 157, it is convenient to detect the position of the bottom support rod 157. When the bottom support rod 157 moves to the bottom surface of the battery cell under the drive of the third driving member 153 and the fourth driving member 155, the second detection member 158 detects the position of the bottom support rod 157 at this time. The second detection member 158 sends the detected signal to the controller, and the controller controls the third driving member 153 and the fourth driving member 155 to stop moving. This can prevent the bottom support rod 157 from continuing to move and colliding with the battery cell, causing damage to the battery cell.

[0144] According to some embodiments of the present application, Figure 1 As shown, the clamping device further includes a tray clamping assembly 16 , wherein the tray clamping assembly 16 is provided on opposite sides of the two support plates 151 .

[0145] In this embodiment, two, three, or other tray clamping assemblies 16 may be connected to each support plate 151 . The specific number may be determined based on actual conditions, and this specification does not limit this.

[0146] In this embodiment, a tray clamping assembly 16 is provided on the clamping device. In this way, the tray clamping assembly 16 is integrated with the battery cell gripper. The entire device can not only grip the battery cells but also the tray, which effectively reduces the cost and floor space of the entire device.

[0147] According to some embodiments of the present application, Figure 10 As shown, the tray clamping assembly 16 includes a sixth driving member 161 and a moving block 162 , wherein the sixth driving member 161 is disposed on the support plate 151 and connected to the moving block 162 for driving the moving block 162 to move along the first direction.

[0148] The sixth driving member 161 in this embodiment can be a cylinder, an electric telescopic rod, etc. The specific one can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0149] The sixth driving member 161 in this embodiment can be fixed to the support plate 151 by bolts, or the sixth driving member 161 can be clamped to the support plate 151. The specific details can be determined according to actual conditions and are not limited in this embodiment of the present specification.

[0150] When in use, the sixth driving member 161 drives the moving block 162 to move along the X-axis direction. At this time, the two sixth driving members 161 located on the two support plates 151 drive the moving blocks 162 to move toward each other, and stop moving when the two moving blocks 162 clamp the battery cell tray.

[0151] It should be noted that the structure of the above-mentioned pallet gripping assembly is merely an example. In other alternative solutions, other structures may also be adopted, for example, the pallet gripping assembly may be a mechanical claw, etc. This application does not impose any particular restrictions on the specific structure of the pallet gripping assembly, as long as the above-mentioned structure can achieve the purpose of this application.

[0152] According to some embodiments of the present application, Figure 10 As shown, the tray clamping assembly 16 also includes a connecting column 163, an insert rod 165 and a clamping plate 166, wherein the connecting column 163 can be extended and retracted along the first direction; the connecting column 163 and the insert rod 165 are both arranged on the side of the moving block 162 away from the sixth driving member 161, and the end of the connecting column 163 away from the moving block 162 is connected to the clamping plate 166, and the end of the insert rod 165 away from the moving block 162 can pass through the clamping plate 166.

[0153] The connecting column 163 in this embodiment can be a telescopic sleeve rod, an electric telescopic rod, etc. The specific one can be determined according to actual conditions, and this embodiment of the present specification does not limit this.

[0154] In this embodiment, the connecting column 163 and the insertion rod 165 are both clamped on the side of the moving block 162 away from the sixth driving member 161, or the connecting column 163 and the insertion rod 165 are both welded to the side of the moving block 162 away from the sixth driving member 161. The specific details can be determined according to actual conditions, and the embodiments of this specification do not limit this.

[0155] In this embodiment, the end of the connecting column 163 away from the moving block 162 can be clamped on the clamping plate 166, or the end of the connecting column 163 away from the moving block 162 can be welded to the clamping plate 166. The specific details can be determined according to actual conditions, and this specification does not limit this.

[0156] In this embodiment, a guide hole 1661 is provided on the clamping plate 166 , and the guide hole 1661 is loosely matched with the insertion rod 165 .

[0157] During use, after the clamping plate 166 clamps the battery tray, the clamping plate 166 compresses the connecting column 163 and retracts it. At this time, the insertion rod 165 can pass through the guide hole 1661 on the clamping plate 166 and be inserted into the battery tray, thereby effectively preventing the battery tray from falling.

[0158] According to some embodiments of the present application, Figure 10 As shown, a guide hole 1661 is provided on the clamping plate 166 , and the end of the insertion rod 165 away from the moving block 162 is a pointed structure, and the end of the insertion rod 165 away from the moving block 162 can pass through the guide hole 1661 .

[0159] During use, after the clamping plate 166 clamps the battery cell tray, the clamping plate 166 compresses the connecting column 163 and retracts it. At this time, the insertion rod 165 can pass through the guide hole 1661 on the clamping plate 166. At this time, since the end of the insertion rod 165 away from the moving block 162 is a pointed structure, the pointed end of the insertion rod 165 can be quickly inserted into the battery cell tray, thereby effectively preventing the battery cell tray from falling.

[0160] According to some embodiments of the present application, Figure 10 As shown, the tray clamping assembly 16 further includes an elastic member 164 , which is disposed between the moving block 162 and the clamping plate 166 .

[0161] In this embodiment, the elastic part may refer to a part that can be deformed under the action of an external force and return to its original shape after the external force is removed. The elastic part can be elastically compressed in the X-axis direction. The elastic part can be made of metal or non-metallic material, such as: a leaf spring, a coil spring, a gas spring, a rubber spring, etc. The specific material can be determined according to actual conditions, and the embodiments of this specification do not limit this.

[0162] Before the clamping plate 166 clamps the cell tray, the elastic member 164 is in its initial state and is uncompressed. When the sixth driving member 161 drives the movable block 162 to move along the X-axis, the movable block 162 simultaneously drives the clamping plate 166 to move along the X-axis. After the clamping plate 166 clamps the cell tray, the clamping plate 166 compresses the connecting column 163, causing it to retract. Simultaneously, the clamping plate 166 compresses the elastic member 164, causing it to retract. At this point, the insertion rod 165 can pass through the guide hole 1661 in the clamping plate 166 and be inserted into the cell tray.

[0163] When the sixth driving member 161 drives the moving block 162 to move in the opposite direction along the X-axis, the insertion rod 165 is pulled out of the battery cell tray and the clamping plate 166 moves away from the battery cell tray. At this time, the pressure of the clamping plate 166 on the elastic member 164 disappears, and the elastic member 164 rebounds and stretches, thereby driving the clamping plate 166 to return to its initial state.

[0164] According to some embodiments of the present application, Figure 10 As shown, the tray clamping assembly 16 further includes a third detecting member 167 . The third detecting member 167 is disposed on the sixth driving member 161 and is used to detect the position of the sixth driving member 161 .

[0165] The third detection member 167 in this embodiment can be a slot-type photoelectric sensor, a position sensor, etc. The specific detection member 167 can be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0166] The third detection member 167 in this embodiment can be connected to the sixth driving member 161 by means of bolts, or the third detection member 167 can be clamped on the sixth driving member 161 . The specific details can be determined according to actual conditions and are not limited in this embodiment of the present specification.

[0167] This embodiment provides a third detection member 167 on the sixth driver 161 to facilitate detection of the position of the sixth driver 161. When the sixth driver 161 drives the clamping plate 166 to clamp the cell tray, the third detection member 167 sends a detected position signal to the controller, which controls the sixth driver 161 to close.

[0168] According to some embodiments of the present application, Figure 2As shown, the clamping device further includes a fourth detecting member 20 , which is disposed on the bracket 10 and is used to detect the position of the tray.

[0171] In this embodiment, the camera may be a CCD camera. Of course, it is understandable that the camera may also be a 3D camera, etc. The specific camera may be determined according to actual conditions, and this embodiment of the specification does not limit this.

[0172] In this embodiment, when it is necessary to clamp a battery cell or a tray, the position of the battery cell or the tray is first detected by a CCD camera, and then the gripper 13 or the tray clamping assembly 16 is controlled to move to a designated position to clamp the battery cell or the tray.

[0173] According to some embodiments of the present application, Figure 2 As shown, the clamping device further includes a light source 21 , which is disposed on the fourth detection member 20 .

[0174] In this embodiment, the light source 21 may be a bar light source, which is located around the fourth detection member 20. When the camera on the fourth detection member 20 is shooting, the light source 21 provides illumination, which is beneficial to the shooting of the camera.

[0176] The fixing member 22 in this example can be inserted into the first movable plate 12, or the fixing member 22 and the first movable plate 12 are threadedly matched. The specific method can be determined according to actual conditions and is not limited in this embodiment of the present specification.

[0177] During use, when the device fails, the first movable plate 12 can be fixed by the fixing member 22 to prevent the first movable plate 12 under repair from falling off relative to the bracket 10.

[0178] According to some embodiments of the present application, Figure 3 Combined with Figure 11As shown, the fixing member 22 includes a fixing seat 221 and a pin shaft 222.

When in use, when the first movable plate 12 needs to be fixed, it is only necessary to pass the pin shaft 222 through the corresponding shaft hole 122 and then extend it into the pin hole of the fixing base 221. In this way, the first movable plate 12 can be conveniently fixed relative to the bracket 10.

[0180] According to some embodiments of the present application, Figure 1 As shown, the clamping device further includes a flange 19 , which is disposed on the bracket 10 .

[0181] The flange 19 in this embodiment is connected to the bracket 10 by bolts. By providing the flange 19 on the bracket 10, it is convenient to connect the entire device with other components.
