[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0039] like Figures 1 to 3 As shown, this utility model embodiment provides a bearing device, characterized in that the bearing device has a first direction (Z) and a second direction (X) that intersect each other in pairs;

[0040] include:

[0041] Vehicle 1.

[0042] The clamping mechanism 2 includes a drive assembly 21 and a transmission assembly 22. The transmission assembly 22 includes a transmission link 221 and a clamping member 222. The transmission link 221 and the drive assembly 21 are movably connected, and the clamping member 222 and the transmission link 221 are slidably connected. The drive assembly 21 can move along a first direction (Z), and the clamping member 222 includes two jaws 2220 that are in relative positions in the first direction (X).

[0043] When the drive assembly 21 moves toward the carrier 1 along the first direction (Z), the transmission link 221 drives the two grippers 2220 to move toward each other along the second direction (X), and the carrier 1 is fixed between the two grippers 2220. The grippers 2220 and the carrier 1 are in arc-shaped contact.

[0044] As can be seen from the above embodiments, in this utility model embodiment, since the clamping mechanism 2 includes a driving component 21 and a transmission component 22, the transmission component 22 includes a transmission link 221 and a clamping member 222. The transmission link 221 and the driving component 21 are movably connected, and the clamping member 222 and the transmission link 221 are slidably connected. The driving component 21 can move along the first direction (Z), and the clamping member 222 includes two jaws 2220 that are in opposite positions in the first direction (X). Therefore, when it is necessary to fix the carrier 1, the driving component 21 can move along the first direction (Z) towards the direction closer to the carrier 1, so that the transmission link 221 drives the two jaws 2220 to move along the second direction (X) towards the direction closer to each other, so that the carrier 1 can be fixed between the two jaws 2220, and the jaws 2220 and the carrier 1 are in arc surface contact. In this way, the carrier 1 can be positioned by two grippers 2220, and the relevant workpiece can be placed on the carrier 1. During the process of gripping the carrier 1 by the grippers 2220, the contact between the grippers 2220 and the carrier 1 is arc-shaped. Compared with planar contact and linear contact, arc-shaped contact can increase the contact area between the grippers 2220 and the carrier 1, and at the same time reduce the friction between the grippers 2220 and the carrier 1. It can reduce the stress concentration caused by point contact, thereby reducing the wear of the grippers 2220 and avoiding affecting the clamping accuracy between the grippers 2220 and the carrier 1. At the same time, it can also avoid the relevant workpiece being directly clamped by the grippers 2220, avoiding damage to the relevant workpiece during the clamping process, thereby improving the accuracy and product quality of the entire battery production process.

[0045] In the above embodiments, the carrier 1 is the main component for carrying the workpiece to be prepared. The carrier 1 can be a plate-like structure, a block-like structure, or other structures with a bearing surface; this application does not limit this. The top surface of the carrier 1 can be provided with suction cups, magnetic components, snap-fit ​​components, or other structures to fix the workpiece to be prepared. The bearing device in this application embodiment is mainly used in the battery manufacturing process, and the workpiece to be prepared can be a battery, circuit board, or other workpiece.

[0046] The clamping mechanism 2 is the main structure for clamping the carrier 1. The clamping mechanism 2 includes a drive component 21 and a transmission component 22. The drive component 21 is movable along a first direction (Z); in other words, the length of the drive component 21 in the first direction (Z) is adjustable. Moving the drive component 21 along the first direction (Z) towards the carrier 1 can be understood as decreasing the distance between the end of the drive component 21 along the first direction (Z) and the carrier 1. Moving the drive component 21 along the first direction (Z) away from the carrier 1 can be understood as increasing the distance between the end of the drive component 21 along the first direction (Z) and the carrier 1. The drive component 21 can be a cylinder, an electric linear actuator, a motor lead screw mechanism, or other device capable of linear motion; this embodiment does not limit this. The transmission link 221 may include one or more of the following: a link structure, a swing guide rod mechanism, a four-bar linkage, a six-bar linkage, and a crank-slider mechanism. The transmission link 221 is movably connected between the clamping member 222 and the drive assembly 21, and can transmit the driving force of the drive assembly 21 to the clamping member 222 so that the clamping member 222 can clamp the carrier 1.

[0047] It should be noted that, in this embodiment, the clamping member 222 includes two grippers 2220 positioned opposite each other in the first direction (X). A drive member can drive a transmission link 221, which in turn increases or decreases the distance between the two grippers 2220 in the second direction (X). When the distance between the two grippers 2220 in the second direction (X) increases, the two grippers 2220 can clamp the carrier 1; when the distance between the grippers 2220 in the second direction (X) decreases, the two grippers 2220 can separate from the carrier 1, thus achieving automatic clamping of the carrier 1. It should also be noted that the contact surface between the grippers 2220 and the carrier 1 is arc-shaped; that is, the contact surface between the grippers 2220 and the carrier 1 is arc-shaped, and the surface of contact between the carrier 1 and the grippers 2220 is arc-shaped. Compared to planar and linear contact, curved surface contact increases the contact area between the gripper 2220 and the carrier 1, while reducing friction between them. This reduces stress concentration caused by point contact and improves the load-bearing capacity and durability of the gripper 2220. Furthermore, curved surface contact can improve the motion stability and accuracy of the gripper 2220 and the carrier 1 during movement, thereby reducing wear on the gripper 2220 and preventing any impact on the clamping accuracy between the gripper 2220 and the carrier 1.

[0048] It should also be noted that, according to Figure 1 In this embodiment, the X-axis and Z-axis intersect, the X-axis and Y-axis intersect, and the Y-axis and Z-axis intersect. For ease of explanation, the first direction is defined as the Z-axis (which is the direction of movement of the driving component 21 in this embodiment), the second direction is defined as the X-axis, and the third direction is defined as the Y-axis. Further explanation: the definition of vertical in the specification should be understood as vertical if it fluctuates by 10% within 90 degrees. That is, the angle between the defined first and second directions should be understood as vertical if it is between 80 and 90 degrees, the angle between the defined first and third directions should be understood as vertical if it is between 80 and 90 degrees, and the angle between the defined second and third directions should be understood as vertical if it is between 80 and 90 degrees.

[0049] In some embodiments, the transmission link 221 includes a main link 2211 and a sliding bracket 2212. The drive assembly 21 is connected to the main link 2211. The main link 2211 extends along a second direction (X). A sliding bracket 2212 is hinged to both ends of the main link 2211 in the second direction (X). A gripper 2220 is installed at the end of each sliding bracket 2212 in the first direction (Z).

[0050] In this embodiment, the main connecting rod 2211 can be a cylindrical rod structure, a square rod structure, or a rod structure of other shapes; this application embodiment does not limit this. The drive assembly 21 is connected to the middle of the main connecting rod 2211. The drive assembly 21 can be directly welded to the middle of the main connecting rod 2211, or it can be detachably connected to the middle of the main connecting rod 2211 using bolts, snap-fit ​​components, or other parts. In this way, when the drive assembly 21 moves along the first direction (Z) towards the carrier 1, it can drive the main connecting rod 2211 to move towards the carrier 1. Since a sliding bracket 2212 is hinged to each end of the main connecting rod 2211 in the second direction (X), and a gripper 2220 is installed at the end of each sliding bracket 2212 in the first direction (Z), when the main connecting rod 2211 moves towards the carrier 1, the bending angle between the sliding bracket 2212 and the main connecting rod 2211 changes, thereby changing the relative position of the grippers 2220 connected to the ends of the sliding bracket 2212. This causes the two grippers 2220 to move towards or away from each other along the second direction (X). In this way, the entire drive only needs to be completed by the drive assembly 21 to position the grippers 2220 on the carrier 1, making it easier to control the positioning accuracy of the grippers 2220 on the carrier 1. It should be noted that the sliding bracket 2212 can be a frame structure, a beam structure, or other structures, and this embodiment does not limit this.

[0051] In some embodiments of the above-described sliding bracket 2212, the sliding bracket 2212 includes two bracket arms 22120 spaced apart along a third direction (Y); the bracket arm 22120 includes a movable part 22121 and a mounting part 22122, the movable part 22121 and the mounting part 22122 are bent to form a bent part 22123, and both the mounting part 22122 and the movable part 22121 extend obliquely away from the main connecting rod 2211 in a first direction (Z); the bent part 22123 is hinged to the end of the main connecting rod 2211 in a second direction (X), the movable part 22121 is movably connected to the main connecting rod 2211, and the mounting part 22122 is connected to the gripper 2220, wherein the third direction (Y) intersects with both the first direction (Z) and the second direction (X).

[0052] In this embodiment, the support arm 22120 can be a U-shaped bent structure. The support arm 22120 can be an integral bent structure or a segmented bent structure. This application embodiment does not limit this. The mounting portion 22122 of the movable portion 22121 included in the support arm 22120 can extend in different tilting directions. Specifically, both the movable portion 22121 and the mounting portion 22122 extend in a tilted direction away from the main connecting rod 2211 in the first direction (Z). The movable portion 22121 and the mounting portion 22122 extend in different directions in the first direction (Z). Thus, since the bent portion 22123 is hinged to the end of the main connecting rod 2211 in the second direction (X), the movable portion 22121 is movably connected to the main connecting rod 2211, and the mounting portion 22122 is connected to the gripper 2220, the main connecting rod 2211 can be moved by the drive assembly 21, and then the movable portion 22121 can be moved by the main connecting rod 2211, ultimately causing the movable portion 22121 to change the relative position of the gripper 2220 connected to the mounting portion 22122. It should be noted that since the gripper 2220 requires a large contact area, two support arms 22120 spaced apart along the third direction (Y) are required to accommodate the larger size of the gripper 2220 in the third direction (Y).

[0053] Regarding the connection between the main connecting rod 2211 and the support arm 22120, in some embodiments, the transmission connecting rod 221 further includes a transfer connecting rod 2213, which is hinged between the main connecting rod 2211 and the bent portion 22123.

[0054] In this embodiment, since the transmission link 221 also includes a transfer link 2213, which is hinged between the main link 2211 and the bent portion 22123, when the main link 2211 moves toward the carrier 1, the included angle between the transfer link 2213 and the main link 2211 changes. The support arm 22120 rotates through the transfer link 2213, which causes the relative position of the gripper 2220 connected to the mounting portion 22122 to change, thereby causing the two grippers 2220 to move toward each other or away from each other along the second direction (X).

[0055] In some embodiments, the drive assembly 21 includes a telescopic rod 211 and a structural support 212. The telescopic rod 211 is mounted on the structural support 212 and can extend and retract along a first direction (Z). The structural support 212 is provided with two sliding arms 2121 at both ends in a second direction (X). Each sliding arm 2121 extends obliquely away from the telescopic rod 211, and each sliding arm 2121 is slidably connected to the movable part 22121 of a support arm 22120.

[0056] In this embodiment, the telescopic rod 211 and the structure can be movably connected via a coupling structure, guide structure, or other hole-shaft structure, allowing the telescopic rod 211 to extend and retract along the first direction (Z). The structural support 212 is a support structure connecting the telescopic rod 211 and the support arm 22120, making the various components of the load-bearing device detachable, facilitating assembly, and making the overall structure of the load-bearing device more compact. Based on this, since the structural support 212 is provided with two sliding arms 2121 at both ends in the second direction (X), each sliding arm 2121 extends obliquely away from the telescopic rod 211, and each sliding arm 2121 is slidably connected to a movable part 22121 of the support arm 22120, when the telescopic rod 211 extends and retracts along the first direction, the sliding arm 2121 can slide in the movable part 22121 of the support arm 22120, and thus, under the limiting action of the sliding arm 2121, the sliding arm 2121 can move along a preset direction.

[0057] In some embodiments, the end of the sliding arm 2121 away from the telescopic rod 211 is provided with a sliding through hole, and the movable part 22121 is slidably connected in the sliding through hole, wherein the axis of the sliding through hole and the plane where the carrier 1 is located intersect at an inclination.

[0058] In this embodiment, since the end of the sliding arm 2121 away from the telescopic rod 211 is provided with a sliding through hole, the movable part 22121 is slidably connected in the sliding through hole. The axis of the sliding through hole intersects the plane where the carrier 1 is located at an inclination. Therefore, the movable part 22121 can move obliquely along the axial direction of the sliding through hole, which facilitates changing the relative position of the gripper 2220 connected on the mounting part 22122. Finally, the two grippers 2220 move in the second direction (X) toward each other or away from each other.

[0059] In some embodiments, the drive assembly 21 further includes a guide structure 213; the guide structure 213 is mounted on the structural support 212, and the guide structure 213 is provided with a guide through hole extending along a first direction (Z), through which the telescopic rod 211 passes.

[0060] In this embodiment, since the guide structure 213 is provided with a guide through hole extending along the first direction (Z), and the telescopic rod 211 passes through the guide through hole, the telescopic rod 211 can always extend and retract along the first direction (Z) under the action of the guide structure 213. It should be noted that the guide structure 213 can be a cylindrical structure, a rod-shaped structure, or other structures with a guide through hole. For example, the guide structure 213 can include a guide plate and a guide cylinder. The guide plate is located at one end of the guide cylinder in the first direction (Z). Both the guide plate and the guide cylinder have a through hole structure. The two through hole structures are connected to form a guide through hole. The guide plate is fixed on the surface of the structure directly facing the carrier 1. The structural support 212 has an installation through hole, and the guide cylinder is embedded in the installation through hole.

[0061] Regarding the structure of the gripper 2220, in some embodiments, the gripper 2220 includes a gripping portion 2221 and a connecting portion 2222. The gripping portion 2221 and the connecting portion 2222 are arranged at a bending angle. The bending portion between the gripping portion 2221 and the connecting portion 2222 is hinged to the end of the mounting portion 22122 near the main connecting rod 2211. The gripping portion 2221 is provided with a gripping groove 22211 on the surface facing the carrier 1. The shape of the gripping groove 22211 and the end of the carrier 1 in the second direction (X) are adapted to each other.

[0062] In this embodiment, since the bent portion between the clamping portion 2221 and the connecting portion 2222 and the end of the mounting portion 22122 near the main connecting rod 2211 are hinged, the clamping portion 2221 is provided with a clamping groove 22211 on the surface facing the carrier 1. The shape of the clamping groove 22211 and the end of the carrier 1 in the second direction (X) are adapted to each other. Therefore, during the process of the jaw 2220 clamping the carrier 1, the clamping groove 22211 and the end of the carrier 1 are in contact, ensuring that the jaw 2220 and the carrier 1 have arc surface contact. Compared with planar contact and linear contact, arc surface contact can increase the contact area between the jaw 2220 and the carrier 1, and at the same time reduce the friction between the jaw 2220 and the carrier 1. It can reduce the stress concentration caused by point contact, thereby reducing the wear of the jaw 2220 and avoiding affecting the clamping accuracy between the jaw 2220 and the carrier 1.

[0063] It should be noted that in the above embodiments, the clamping part 2221 can be a plate-like structure or a block-like structure. The clamping groove 22211 on the surface of the clamping part 2221 facing the carrier 1 can be an arc-shaped groove, concave in the direction away from the carrier 1. The two ends of the carrier 1 in the second direction (X) can be set as cylindrical structures, so that the shapes of the clamping groove 22211 and the ends of the carrier 1 in the second direction (X) are compatible, thereby increasing the contact area between the clamping groove 22211 and the ends of the carrier 1 in the second direction (X). In addition, since the bent portion between the clamping part 2221 and the connecting part 2222 and the end of the mounting part 22122 near the main connecting rod 2211 are hinged, when the mounting part 22122 moves, the gripper 2220 and the mounting part 22122 can rotate, thereby changing the relative position of the gripper 2220.

[0064] In some embodiments, the carrier device further includes an elastic element 3, which is installed between the two ends of the connecting portion 2222 and the mounting portion 22122 that are in opposite positions in the first direction (Z). When the carrier 1 is fixed between the two grippers 2220, the elastic element 3 is in a compressed state.

[0065] In this embodiment, the elastic element 3 can be a spring, elastic block, rubber strip, or other component with a certain elasticity that can return to its initial state; this embodiment does not limit this. Thus, since the elastic element 3 is installed between the two ends of the connecting portion 2222 and the mounting portion 22122, which are in opposite positions in the first direction (Z), when the carrier 1 is fixed between the two grippers 2220, the elastic element 3 is in a compressed state. Therefore, the elastic force of the elastic element 3 can provide an additional clamping force to the grippers 2220, thereby increasing the clamping effect of the grippers 2220 on the carrier 1 support and improving the stability of the grippers 2220 on the carrier 1.

[0066] In some embodiments, a roller 11 is hinged to each of the two ends of the carrier 1 in the second direction (X), the groove surface of the clamping groove 22211 is an arc surface, the groove surface of the clamping groove 22211 is provided with at least one positioning protrusion 22212, and the roller 11 is provided with at least one positioning groove 111. When the carrier 1 is fixed between the two grippers 2220, the positioning protrusion 22212 is embedded in the positioning groove 111.

[0067] In this embodiment, since the groove surface of the clamping groove 22211 is provided with at least one positioning protrusion 22212, and the roller 11 is provided with at least one positioning groove 111, when the carrier 1 is fixed between the two jaws 2220, the positioning protrusion 22212 is embedded in the positioning groove 111. Therefore, the fastening of the connection between the jaws 2220 and the carrier 1 can be further increased by the snap-fit ​​between the positioning protrusion 22212 and the positioning groove 111, and the relative displacement between the jaws 2220 and the carrier 1 can be avoided by the snap-fit ​​between the positioning protrusion 22212 and the positioning groove 111. In addition, it should be noted that since the carrier 1 is hinged to a roller 11 at both ends in the second direction (X), the roller 11 can rotate during the process of the jaws 2220 and the carrier 1 being in full contact. As the roller rotates, it gradually comes into contact with the clamping groove 22211 of the jaws 2220, thereby facilitating the clamping between the jaws 2220 and the carrier 1.

[0068] As can be seen from the above embodiments, in this utility model embodiment, since the clamping mechanism 2 includes a driving component 21 and a transmission component 22, the transmission component 22 includes a transmission link 221 and a clamping member 222. The transmission link 221 and the driving component 21 are movably connected, and the clamping member 222 and the transmission link 221 are slidably connected. The driving component 21 can move along the first direction (Z), and the clamping member 222 includes two jaws 2220 that are in opposite positions in the first direction (X). Therefore, when it is necessary to fix the carrier 1, the driving component 21 can move along the first direction (Z) towards the direction closer to the carrier 1, so that the transmission link 221 drives the two jaws 2220 to move along the second direction (X) towards the direction closer to each other, so that the carrier 1 can be fixed between the two jaws 2220, and the jaws 2220 and the carrier 1 are in arc surface contact. In this way, the carrier 1 can be positioned by two grippers 2220, and the relevant workpiece can be placed on the carrier 1. During the process of gripping the carrier 1 by the grippers 2220, the contact between the grippers 2220 and the carrier 1 is arc-shaped. Compared with planar contact and linear contact, arc-shaped contact can increase the contact area between the grippers 2220 and the carrier 1, and at the same time reduce the friction between the grippers 2220 and the carrier 1. It can reduce the stress concentration caused by point contact, thereby reducing the wear of the grippers 2220 and avoiding affecting the clamping accuracy between the grippers 2220 and the carrier 1. At the same time, it can also avoid the relevant workpiece being directly clamped by the grippers 2220, avoiding damage to the relevant workpiece during the clamping process, thereby improving the accuracy and product quality of the entire battery production process.
