Description

Technical Field

[0001] This invention relates to the field of new energy battery production and manufacturing, specifically to a locking device and an automated assembly line for new energy battery packs. Background Technology

[0002] Currently, the production processes of automated assembly lines for new energy vehicle battery packs are becoming increasingly diversified. When assembling battery packs onto the vehicle chassis, the battery packs may be placed horizontally or at an angle. The angled placement can meet the requirements of complex assembly processes and the flexible production of automated assembly lines, ensuring high-quality and high-yield completion of assembly tasks. However, in the existing technology, the battery pack assembly station places the battery packs on a pallet and uses positioning components to position them. While this can meet the requirements for horizontal assembly, the positioning accuracy of the workpiece is poor. Furthermore, during angled assembly, the positioning components bear a large supporting load, which can lead to breakage of the positioning components. In addition, the pallet can only hold one type of battery pack, resulting in poor compatibility and requiring frequent pallet replacements during assembly. Summary of the Invention

[0003] The purpose of this disclosure is to provide a locking device and an automated assembly line for new energy battery packs, thereby overcoming, at least to some extent, the problems caused by the limitations and defects of related technologies.

[0004] The first aspect of this disclosure provides a locking device, comprising:

[0005] Base;

[0006] The first limiting member is movably disposed on the base. The first limiting member has a first limiting surface and an inclined pushing surface that is inclined relative to the first limiting surface. The first limiting surface can abut against the bottom surface of the workpiece and can move from the initial position in the Y direction along the Y axis to the Y direction locking position under the pressure of the workpiece.

[0007] The second limiting member is movably disposed on the base. The second limiting member has a second limiting surface and a movable mating surface, and the movable mating surface abuts against the inclined pushing surface.

[0008] When the first limiting member moves from its initial position along the Y-axis to its Y-direction locking position, the moving mating surface can move along the X-axis under the push of the inclined pushing surface, and at the same time drive the second limiting surface to move from its initial position along the X-axis to its X-direction locking position. When the second limiting surface is in the X-direction locking position, it can abut against the side of the workpiece.

[0009] In an exemplary embodiment of this disclosure, the first limiting member has a third limiting surface, which is disposed opposite to the inclined pushing surface along the X-axis direction; the second limiting member has a limiting mating surface, which is disposed opposite to the moving mating surface along the X-axis direction.

[0010] The inclined pushing surface abuts against the moving mating surface, and the third limiting surface and the limiting mating surface are provided with a distance D1. When the first limiting member moves along the Y-axis from the initial position in the Y direction to the locking position in the Y direction, the distance D1 gradually decreases.

[0011] In one exemplary embodiment of this disclosure, the first limiting member includes:

[0012] A first slider, the first slider having the inclined pushing surface and the third limiting surface, the first slider having a first mounting groove, the opening of the first mounting groove penetrating the top surface of the first slider;

[0013] A support member is movably installed in the first mounting groove and extends out of the first mounting groove to abut against the bottom surface of the workpiece. The surface of the support member that abuts against the workpiece is the first limiting surface.

[0014] A first spring is installed in the first mounting groove, with one end of the first spring abutting against the support member and the other end abutting against the bottom of the first mounting groove.

[0015] In an exemplary embodiment of this disclosure, the first limiting member is further provided with a second mounting groove, the opening of the second mounting groove penetrating the bottom surface of the first limiting member, and the outer wall surface of the second mounting groove away from the first mounting groove is the third limiting surface;

[0016] The locking device includes a first reset member, which includes a second spring. One end of the second spring is installed in the second mounting groove and abuts against the bottom of the second mounting groove, while the other end of the second spring abuts against the base.

[0017] In one exemplary embodiment of this disclosure, the second limiting member includes:

[0018] The second slider is provided with a limiting hole, the limiting hole is provided with the moving mating surface and the limiting mating surface, and the first limiting member moves in the limiting hole along the Y-axis direction;

[0019] A workpiece limiting component is provided, which is perpendicular to the second slider. The workpiece limiting component has a second limiting surface, which is perpendicular to the first limiting surface.

[0020] In one exemplary embodiment of this disclosure, the second reset member includes

[0021] The third mounting groove is provided on the side of the base, and the opening of the third mounting groove faces the side where the workpiece limiting member is located.

[0022] The third spring has one end abutting against the bottom of the third mounting groove, and the other end connected to the second limiting member.

[0023] In one exemplary embodiment of this disclosure, the base is provided with a clearance groove, and the side wall of the clearance groove is provided with two first sliding grooves. The first sliding grooves extend on the X-axis, and the second slider is slidably disposed in the first sliding groove. The limiting hole of the second slider communicates with the clearance groove.

[0024] In one exemplary embodiment of this disclosure, the locking device includes a sliding assembly, which includes a second slide groove, a third slide groove, and a slide rail. The second slide groove and the third slide groove extend along the Y-axis, and the second slide groove is disposed on the side wall of the clearance groove. The third slide groove is disposed on the second limiting member, and the second slide groove communicates with the third slide groove. The slide rail is disposed on the first limiting member and is movably disposed in the second slide groove and the third slide groove.

[0025] In one exemplary embodiment of this disclosure, the first limiting member is provided with a limiting portion for limiting the distance the first limiting member moves on the Y-axis. The limiting portion protrudes from the second limiting surface and has a gap with the first limiting member in the X-axis direction.

[0026] The second aspect of this disclosure provides an automated assembly line for new energy battery packs, which is used for automated assembly of new energy battery packs. It includes a tray, a positioning component, and a locking device provided in the first aspect. The positioning component and the locking device are disposed on the tray. The positioning component is used to fix the workpiece in the X-axis direction. When the second limiting surface is in the locking position, the positioning component cooperates with the second limiting surface to fix the workpiece.

[0027] The locking device and automatic assembly line for new energy battery packs disclosed herein have the following beneficial effects: When assembling new energy battery packs on the automatic assembly line, the locking device installed on the tray, in conjunction with the positioning component on the tray, can fix and lock the battery pack, satisfying both horizontal and inclined assembly requirements. The locking device includes a base, a first limiting component, and a second limiting component. The first limiting component has a first limiting surface and an inclined pushing surface that is inclined relative to the first limiting surface. The first limiting surface can abut against the bottom surface of the workpiece and can move from its initial position along the Y-axis to the locking position under the pressure of the workpiece. The second limiting component has a second limiting surface and a moving mating surface. The moving mating surface abuts against the inclined pushing surface. When the first limiting component moves from its initial position along the Y-axis to the locking position... The movable mating surface moves along the X-axis under the pushing force of the inclined pushing surface. The second limiting surface and the movable mating surface move simultaneously, moving from the initial position to the locking position along the X-axis. When assembling different battery packs, the locking position changes according to the specifications of the battery pack, thus enabling compatibility with battery packs of different specifications. When the second limiting surface is in the locking position, it can abut against the side of the workpiece, locking the battery pack through the first and second limiting surfaces. When the locking device is tilted, the pressure of the battery pack is distributed on the second and first limiting surfaces, reducing the supporting load of the positioning component and ensuring that the positioning component will not break. When the locking device and the positioning component fix the battery pack and tilt the assembly, the battery pack will not shift, improving the assembly accuracy.

[0028] Other features and advantages of this disclosure will become apparent from the following detailed description, or may be learned in part from practice of this disclosure.

[0046] The present disclosure will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0047] It should be noted that "multiple" in this article refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0048] The first aspect of this disclosure provides a locking device, including a base 10, a first limiting member 100, and a second limiting member 200. The first limiting member 100 is movably disposed on the base 10 and moves along the Y-axis, and the second limiting member 200 is movably disposed on the base 10 and moves along the X-axis. When the first limiting member 100 moves along the Y-axis under the pressure of the workpiece, the first limiting member 100 pushes the second limiting member 200 to move along the X-axis. After the second limiting member 200 moves to the locking position, it abuts against the workpiece to lock the workpiece.

[0049] Reference Figure 1The first limiting member 100 of the locking device is movably disposed on the base 10. The first limiting member 100 has a first limiting surface 100L and an inclined pushing surface 100M inclined relative to the first limiting surface 100L. The first limiting surface 100L can abut against the bottom surface of the workpiece and can move from the initial position 100A in the Y direction to the Y locking position 100B under the pressure of the workpiece. The second limiting member 200 is movably disposed on the base 10. The second limiting member 200 has a second limiting surface 220M and a moving mating surface 200M, which moves and engages... When the first limiting member 100 moves from the initial position 100A in the Y direction to the locking position 100B in the Y direction, the moving mating surface 200M moves along the X direction under the pushing force of the inclined pushing surface 100M. The second limiting surface 220M and the moving mating surface 200M move simultaneously. When moving along the X direction, the second limiting surface 220M moves from the initial position 200A in the X direction to the locking position 200B in the X direction. When the second limiting surface 220M is in the locking position 200B in the X direction, it can abut against the side of the workpiece.

[0050] Specifically, the first limiting member 100 can move along the Y-axis but cannot move along the X-axis. The first limiting member 100 includes an inclined pushing surface 100M, a third limiting surface 100N, and a first limiting surface 100L. The inclined pushing surface 100M is disposed on the upper surface of the first limiting member 100. The inclined pushing surface 100M and the third limiting surface 100N are disposed opposite each other along the X-axis. The inclined pushing surface 100M is inclined relative to the first limiting surface 100L with an angle of α. The third limiting surface 100N is perpendicular to the first limiting surface 100L with an angle of β relative to the inclined pushing surface 100M. β and α are complementary angles. The first limiting surface 100L contacts the bottom surface of the workpiece and moves along the Y-axis under the gravity of the workpiece.

[0051] In addition, the second limiting member 200 can move along the X-axis but cannot move along the Y-axis. The second limiting member 200 is provided with a limiting hole 211, which includes a movable mating surface 200M. The movable mating surface 200M is inclined along the Y-axis and abuts against the inclined pushing surface 100M. When the movable mating surface 200M and the inclined pushing surface 100M are planes, their two surfaces coincide. A clearance area is provided on one side of the limiting hole 211 relative to the third limiting surface 100N. The width of the clearance area is selected according to actual needs so that when the first limiting member 100 moves, the second limiting member 200 has enough space to move along the X-axis.

[0052] In summary, when the first limiting surface 100L moves along the X direction under the pressure of the workpiece, the moving mating surface 200M and the inclined pushing surface 100M remain coplanar and move relative to each other. The first limiting member 100 is wider at the bottom and narrower at the top and cannot move in the X-axis direction, thereby pushing the second limiting member to move in the X-axis direction. Furthermore, the limiting hole 211 has a sufficient clearance area on the side opposite to the third limiting surface 100N, which can ensure that the second limiting surface 220M abuts against the side of the workpiece.

[0053] Reference Figure 2 and Figure 3 The base 10 includes a vertical clearance groove 11, which extends through both sides of the base 10 in the X-axis direction and through the top in the Y-axis direction while remaining closed at the bottom. The clearance groove 11 is provided with a first sliding groove 12, which is provided on the side of the clearance groove 11. There are two first sliding grooves 12, which are provided along the X-axis direction. The bottom of the base 10 is provided with fixing holes to fix the base 10 on the tray.

[0054] In addition, the base 10 includes a third mounting groove 410 and a spring mounting hole 340. The third mounting groove 410 is provided to facilitate the installation of the second reset member 400 and to make it easier to realize its function. The spring mounting hole 340 is provided to facilitate the installation of the first reset member 300 and to make it easier to realize its function. The third mounting groove 410 and the spring mounting hole 340 will be described in detail later.

[0055] Reference Figure 2 and Figure 4The first limiting member 100 includes a first slider 110 and a support member 130. The first limiting surface 100L is the top surface of the support member 130. The first slider 110 is generally hexahedral. Concave surfaces, convex surfaces, countersunk surfaces, holes, etc., can be provided on any surface of the hexahedron for ease of assembly or to better realize its function. No specific limitation is made here. The six surfaces include opposing inclined pushing surfaces 100M and third limiting surfaces 100N. The inclined pushing surfaces 100M and third limiting surfaces 100N are arranged opposite each other along the X-axis. The third limiting surface 100N is parallel to the Y-axis. The inclined pushing surface 100M forms an angle β with the Y-axis. The first slider 110 is provided with a first mounting groove 111. The opening of the first mounting groove 111 penetrates the top surface of the first slider 110. A limiting flange 112 is provided on the first mounting groove 111. The limiting flange 112 is located at the top of the first mounting groove 111. The support member 130 is installed in the first mounting groove 111 and can slide in the first mounting groove 111. The limiting flange 112 can prevent the support member 130 from leaving the first mounting groove 111. A first spring 140 is installed in the first mounting groove 111. The top end of the first spring 140 abuts against the bottom surface of the support member 130, and the bottom end of the first spring 140 abuts against the bottom surface of the first mounting groove 111. When the workpiece is pressed down and contacts the support member 130, the first spring 140 contracts. When the workpiece is unloaded, the first spring 140 extends to reset the support member 130. The first spring 140 can also act as a buffer when the workpiece is pressed down.

[0056] Specifically, the first limiting member 100 also includes a cover member 120, a limiting flange 112 is provided on the cover member 120, a support member 130 is a support column, a limiting cap is provided at the bottom of the support column, the support column passes through the cover member 120, and when the limiting cap slides in the first mounting groove 111, the limiting flange 112 will restrict the limiting cap from sliding out of the first mounting groove 111.

[0057] In some embodiments, the workpiece acts directly on the upper surface of the first slider 110, and the first limiting surface 100L is the top surface of the first slider 110, that is, the surface where the support member 130 abuts against the workpiece.

[0058] In some embodiments, the support member 130 and the first slider 110 are integrally formed, and the first limiting surface 100L is the top surface of the support member 130.

[0059] Reference Figure 2 and Figure 4The second limiting member 200 includes a second slider 210 and a workpiece limiting member 220. The workpiece limiting member 220 is vertically disposed at one end of the second slider 210. The second slider 210 is provided with a limiting hole 211, which matches the first slider 110. The first slider 110 can move along the Y-axis in the limiting hole 211. The moving mating surface 200M and the limiting mating surface 200N are disposed opposite each other in the limiting hole 211 along the X-axis direction. The moving mating surface 200M and the limiting mating surface 200N are planes. The moving mating surface 200M and the inclined pushing surface 100M are coplanar and slide relative to each other. There is a gap between the limiting mating surface 200N and the third limiting surface 100N so that the first slider 110 can slide a sufficient distance. When the first slider 110 moves along the Y-axis, the second slider 210 will move on the X-axis, thereby driving the workpiece limiting member 220 to move.

[0060] Specifically, the distance between the limiting mating surface 200N and the third limiting surface 100N is D1. When the workpiece is placed on the first limiting surface 100L, one side of the workpiece is close to the second limiting surface 220M and has a distance D2. When the workpiece is pressed down, the inclined pushing surface 100M pushes the moving mating surface 200M to move, thereby moving the second slider 210. The distance D1 decreases, and the second limiting surface 220M of the workpiece limiting member 220 moves closer to the side of the workpiece, thereby decreasing D2. When D2 is zero, D1 is greater than or equal to zero. That is, the limiting mating surface 200N and the third limiting surface 100N can be coplanar or non-coplanar. When the workpiece continues to press down and D1 continues to decrease, the workpiece will slide in the X-axis direction under the push of the workpiece limiting member 220. When D1 is equal to zero, the workpiece is locked.

[0061] In some embodiments, two locking devices are provided opposite to each other. The second limiting surfaces 220M of the locking devices are close to each other or far apart. When they are close to each other, the two second limiting surfaces 220M can clamp the workpiece. When D2 is zero, the workpiece will not move in the X-axis direction. At this time, D1 is greater than or equal to zero, which will not affect the stability of the workpiece and can lock the workpiece.

[0062] In some embodiments, the workpiece can only move on the Y-axis and not on the X-axis. This is achieved by installing a positioning element 20 on one side of the workpiece. The positioning element 20 is set on the pallet of the assembly line and is fixedly installed perpendicular to the Y-axis. When the workpiece is inserted into the positioning element, the second limiting surface 220M and the positioning element clamp the workpiece when D2 is zero. The workpiece will not move in the X-axis direction. At this time, D1 is greater than or equal to zero and will not affect the stability of the workpiece, while locking the workpiece can be achieved.

[0063] Reference Figure 4 and Figure 6The first limiting member 100 is also provided with a second mounting groove 310. The groove opening of the second mounting groove 310 penetrates the bottom surface of the first limiting member 100. The outer wall surface of the second mounting groove 310 away from the first mounting groove 111 is the third limiting surface 100N. The locking device includes a first reset member 300. The first reset member 300 includes a second spring 320. One end of the second spring 320 is installed in the second mounting groove 310 and abuts against the bottom of the second mounting groove 310. The other end of the second spring 320 abuts against the base 10.

[0064] Specifically, the second mounting groove 310, the second spring 320, and the spring mounting hole 340 on the base 10 work together to reset the first limiting member 100. The second mounting groove 310 is located at the bottom of the first slider 110 and is offset from the first mounting groove 111. The second mounting groove 310 is located along the Y-axis direction. The bottom of the second mounting groove 310 passes through the first slider 110 and the top is closed. The second spring 320 is installed between the second mounting groove 310 and the spring mounting hole 340. The ground of the first slider 110... There is a gap between the second spring 320 and the ground of the clearance groove 11. The second spring 320 is partially located in the second mounting groove 310 and partially located in the gap. The bottom part of the second spring 320 is located in the spring mounting hole 340. The spring mounting hole 340 penetrates the bottom surface of the base and the bottom surface of the clearance groove 11. The spring mounting hole 340 is threaded. A part of the first support rod 330 is used for threaded assembly with the spring mounting hole 340. A part of the first support rod 330 extends into the second spring 320 and is spaced from the top surface of the second mounting groove 310.

[0065] Specifically, when the first slider 110 moves on the Y-axis, the second spring 320 extends and retracts. When the first slider 110 is in the locked state, the second spring 320 retracts. When the workpiece is unloaded, the second spring 320 extends to reset the first slider 110.

[0066] Reference Figure 4 and Figure 5 The locking device also includes a second reset member 400, which includes a third spring 420, a second support rod 430, and a third mounting groove 410 disposed on the base 10. The third mounting groove 410 is disposed along the X-axis direction, and the opening of the third mounting groove 410 faces the side of the workpiece limiting member 220. The third mounting groove 410 is equipped with a third spring 420, one end of which is connected to the second slider 210 and the other end is connected to the bottom of the third mounting groove 410.

[0067] Specifically, a support plate 230 is mounted on the workpiece limiting member 220. The support plate 230 extends to both sides of the workpiece limiting member 220. A second support rod 430 is mounted on the extended part. The second support rod 430 is partially inserted into the third spring 420 and has a gap with the bottom of the third mounting groove 410. When the second slider 210 is pushed by the first slider 110 on the X-axis, the third spring 420 extends. When the first slider 110 returns to its original position on the Y-axis, the third spring 420 contracts and drives the second slider 210 to return to its original position on the X-axis.

[0068] Reference Figure 6 The locking device also includes a limiting part 600, which is disposed parallel to the X-axis direction on the workpiece limiting member 220. The limiting part 600 protrudes from the second limiting surface 220M and partially abuts against the first limiting surface 100L. The limiting part 600 has a distance from the cover member 120 or the support column in the X-axis direction. The distance between the limiting part 600 and the cover member 120 or the support column in the X-axis direction is greater than or equal to the distance D1, so as to prevent the limiting part 600 from abutting against the cover member 120 or the support column before the second limiting surface 220M abuts against the workpiece. When the first limiting member 100 moves upward along the Y-axis, the limiting part 600 can restrict the position of the first limiting member 100 and prevent it from disengaging from the second limiting member 200 under the action of elastic force.

[0069] Reference Figure 2 and Figure 3 The locking device also includes a sliding assembly 500, which includes a second slide groove 510, a third slide groove, and a slide rail 530. The two slide rails 530 are fixedly mounted on the first slider 110. The second slide groove 510 is mounted along the Y-axis on the side wall of the clearance groove 11 of the base 10. The third slide groove is mounted along the Y-axis on the limiting hole 211 of the second slider. The second slide groove 510 and the third slide groove are connected. The slide rail 530 is mounted on the side of the first limiting member 100. The slide rail 530 slides in the second slide groove 510 and / or the third slide groove. The slide rail 530 is spaced from the side of the second slide groove 510 and the third slide groove near the limiting mating surface 200N.
