Square power battery CTP module boxing clamp

Abstract

This invention is a square power battery CTP module loading fixture, comprising: a mounting base; two lateral clamping mechanisms and two end clamping mechanisms; a quick-change mechanism disposed below the mounting base; and a first drive mechanism disposed on the mounting base, with its extended end fixedly connected to the quick-change mechanism. Lateral clamping mechanisms are slidably mounted on the left and right sides of the mounting base, and end clamping mechanisms are slidably disposed on the front and rear sides of the mounting base. This allows the module to be gripped from the workstation by clamping it in the front-rear and left-right directions. When the module needs to be placed into the battery pack, the first drive mechanism operates, and its extended end is connected to the quick-change mechanism. The quick-change mechanism acts on the upper surface of the module, reducing the clamping force of the end clamping mechanism and the lateral clamping mechanism on the module, and providing a downward pushing force to press the module into the battery pack. This improves the efficiency of the grippers in grasping the module and the efficiency of pressing the module into the battery pack.

Description

Technical Field

[0001] This invention relates to clamps, and more particularly to a clamp for inserting square power battery CTP modules into a box. Background Technology

[0002] With the booming market and demand for electric vehicles, the need for power batteries is also increasing, which is putting pressure on power battery production.

[0003] Production line standards and requirements are increasingly stringent, making capacity expansion on production lines an urgent priority. A power battery system is an energy storage device used to power electric vehicles, consisting of one or more battery packs and a battery management (control) system. Battery packs rely heavily on modules; a power battery module is an assembly of individual power battery cells connected in series and parallel, protected by a circuit board and casing, capable of directly providing electrical energy. It is one of the secondary structures of a power battery system. In practical applications, power battery modules require high-quality, high-efficiency, and high-precision placement within the battery pack. Currently, due to a lack of suitable equipment, manual placement is predominantly employed. However, manual placement suffers from slow efficiency, high risk, and poor precision.

[0004] In the existing technology, there are automated devices for grabbing power battery modules. However, the existing devices have problems such as poor module compatibility, modules being easy to fall off, and inability to accurately press the modules into the battery pack.

[0005] In addition, the previous module packing process required several machines to perform the packing function, meaning that a module of a certain specification required several machines to be packed into the box, and it was not universal.

[0006] In summary, improving the efficiency of the gripper in grasping the module and pressing the module into the battery pack has become an urgent problem for researchers in this field. Summary of the Invention

[0007] The technical problem to be solved by this invention is: how to improve the efficiency of gripper grasping the module and press the module into the battery pack;

[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0009] This invention is a square power battery CTP module loading fixture, comprising: a mounting base; two lateral clamping mechanisms slidably disposed on both sides of the mounting base, the two lateral clamping mechanisms being adapted to clamp the left and right sides of the module; two end clamping mechanisms slidably disposed at both ends of the bottom of the mounting base, and adapted to clamp the front and rear ends of the module; a quick-change mechanism disposed below the mounting base; and a first drive mechanism disposed on the mounting base, the extended end of which is detachably connected to the quick-change mechanism via a zero-point mechanism.

[0010] In this solution, lateral clamping mechanisms are slidably installed on the left and right sides of the mounting base. The lateral clamping mechanisms are used to clamp the left and right sides of the module. End clamping mechanisms are slidably installed on the front and rear sides of the mounting base. The end clamping mechanisms are used to clamp the front and rear ends of the module. In this way, the module can be clamped from the workstation by clamping the module in the front-back and left-right directions.

[0011] When the module needs to be placed into the battery pack, the first drive mechanism works, and its extended end is connected to the quick-change mechanism. The quick-change mechanism acts on the upper surface of the module. At this time, the clamping force of the end clamping mechanism and the side clamping mechanism on the module is reduced, and the module is given a downward pushing force to press the module into the box.

[0012] The first drive mechanism can be an electric cylinder, with its cylinder body inverted and mounted on the mounting base, and its output end passing through the mounting base and connected to a quick-change mechanism.

[0013] This fixture can not only accommodate square CTP power battery modules (battery packs), but also modules with rectangular cross-sections.

[0014] In order to improve the module gripping efficiency, the present invention adopts a quick-change mechanism with a suction cup for adsorbing the module;

[0015] The suction cup can adhere to the upper surface of the module. When clamping the module, there is a clamping force exerted on the module by the lateral clamping mechanism and the end clamping mechanism, as well as the suction force of the suction cup on the module.

[0016] To illustrate the specific structure of the lateral clamping mechanism, the present invention employs the following lateral clamping mechanism: an extension seat connected to the side of the mounting seat; a sliding plate slidably disposed at the bottom of the extension seat; a second driving assembly adapted to drive the sliding plate to move linearly along the extension seat; and a third driving assembly fixed to the end face of the sliding plate, with a clamping plate fixed to its output end.

[0017] In this solution, a sliding plate is slidably provided at the bottom of the extension seat. Under the drive of the second drive component, the sliding plate moves closer to or away from the left and right sides of the module. A clamping plate is provided on the sliding plate. Under the drive of the third drive component, the clamping plate moves closer to or away from the sliding plate, that is, the clamping plate moves closer to or away from the left and right sides of the module. The clamping plate directly acts on the sides of the module.

[0018] In other words, the sliding plate performs a primary motion under the drive of the second drive component, and the clamping plate performs a secondary motion under the drive of the third drive component.

[0019] In addition, an extension plate is fixed on the sliding plate, and a trigger is set at the bottom of the second sliding plate. When the sliding plate drives the extension plate to move closer to the module and touches the trigger, the third drive component can then be activated to extend the clamping plate. This prevents the lateral clamping mechanism from being mispositioned, causing the sliding plate to be located outside the workstation. When the clamping plate extends, it acts on the side wall of the workstation, not the side wall of the module. In summary, the first-level movement of the sliding plate can determine whether the clamping plate is located on the side of the module.

[0020] To illustrate the specific structure of the second drive assembly, the present invention uses the second drive assembly comprising: a motor, which is fixed on the extension seat; a lead screw, which is rotatably disposed at the bottom of the extension seat, one end of which is connected to the output end of the motor via a sprocket; and a lead nut, which is fixed to the top of the sliding plate and connected to the lead screw.

[0021] The motor is horizontally fixed on the extension base. The top of the sliding plate and the bottom of the extension base are slidably connected by a slider and a slide rail. The length of the slide rail is parallel to the length of the mounting base. The lead screw is installed at the bottom of the extension base and can rotate freely. The lead screw threadedly engages with the lead screw on the top of the sliding plate. The output end of the motor is connected to the end of the lead screw by a sprocket. When the motor rotates, the lead screw rotates, thereby realizing the translation of the lead screw nut on the lead screw, and thus the translation of the sliding plate.

[0022] To illustrate the specific structure of the third drive assembly, the present invention employs a third drive assembly comprising: two cylinders, the cylinder bodies of which are fixed to the sliding plate, and the two ends of the clamping plate being respectively connected to the output ends of the cylinders; two guide rods, which pass through the sliding plate and connect the ends of the two guide rods to the clamping plate respectively, and the other ends of the two guide rods being connected to a connecting rod;

[0023] The cylinders are symmetrically fixed on the sliding plate. The two ends of the clamping plate are connected to the output ends of the cylinders respectively. The output ends of the cylinders extend out, driving the clamping plate away from the sliding plate. In order to ensure that the clamping plate remains horizontal during the extension process, two guide rods are provided on the clamping plate. The two guide rods pass through the sliding plate, and the two ends of the connecting rod are respectively connected to one end of the two guide rods.

[0024] To illustrate the specific structure of the end clamping mechanism, the present invention employs an end clamping mechanism comprising: a second sliding plate slidably disposed at the bottom of the mounting base; a gripper vertically connected to the second sliding plate; and a third driving mechanism fixed on the mounting base, the output end of which is fixedly connected to the second sliding plate. When the third driving mechanism is in operation, it is adapted to drive the second sliding plate together with the gripper to move linearly along the length direction of the mounting base.

[0025] In this solution, the second sliding plate is slidably disposed at the bottom of the mounting base by a combination of slider and slide rail, and is adapted to move along the length direction of the mounting base. The gripper is vertically disposed at the bottom of the second sliding plate. The third drive mechanism works to drive the second sliding plate together with the gripper to move along the length direction of the mounting base until the gripper abuts against the end face of the module, thereby achieving clamping of the end of the gripper.

[0026] To illustrate the specific structure of the third drive mechanism, this invention uses a horizontally positioned electric cylinder as the third drive mechanism.

[0027] The electric cylinder of the third drive mechanism is horizontally fixed on the mounting base, and the output end of the electric cylinder is fixedly connected to the seat on the second sliding plate.

[0028] In order for the gripper to adapt to modules of different widths, the gripper needs to be replaced. To achieve the replacement of the gripper, the present invention adopts a gripper with a pin hole at the top; the top surface of the second sliding plate is provided with a pin part having a second pin hole; a pin cylinder is fixed on the end face of the second sliding plate, and its output end is provided with a pin; when the pin cylinder works, the pin passes through the pin hole and the second pin hole in sequence, connecting the second sliding plate and the gripper.

[0029] The pin hole at the top of the gripper passes through the second sliding plate, so that the pin hole and the pin hole of the pin part are concentric. The output end of the pin cylinder is connected to the pin. The pin passes through the second pin hole and the pin hole, and the gripper and the second sliding plate are inserted and connected, realizing the detachable connection of the gripper, which facilitates the replacement of grippers of different widths to adapt to modules of different widths.

[0030] To prevent the module from falling during transport, the present invention also includes two bottom-supporting mechanisms, which are respectively fixedly connected to the lateral clamping mechanism. After the module is clamped, the bottom plate of the bottom-supporting mechanism is located below the module.

[0031] The bottom support mechanism is connected to the side clamping mechanism. The bottom plate of the bottom support mechanism is adapted to move to the bottom of the module. When the module falls, the two bottom plates of the two bottom support mechanisms will support the module.

[0032] To illustrate the specific structure of the bottom-supporting mechanism, the present invention further includes: a support plate parallel to the length direction of the mounting plate, the middle part of which is fixedly connected to the lateral clamping mechanism; a first connecting plate disposed at the end of the support plate and moving along the width direction of the mounting base under the drive of the fourth driving component; a second connecting plate slidably connected to the first connecting plate and raised and lowered by the drive frame of the fifth driving component; and the two ends of the bottom-supporting plate are fixedly connected to the bottom of the two second connecting plates.

[0033] The support plate is set parallel to the length direction of the mounting base and connected to the lateral clamping mechanism. Specifically, the middle part of the support plate is connected to the sliding plate. In this way, the support plate can be moved closer to or away from the mounting base under the drive of the second drive component. The top of the first connecting piece is slidably connected to the end of the support plate through a combination of slide rails and sliders. The first connecting plate moves along the width direction of the mounting base under the action of the fourth drive component. The second connecting plate is slidably connected to the first connecting plate through a combination of vertically set slide rails and sliders. Under the drive of the fifth drive component, the second connecting plate is raised and lowered. The second connecting plate has an L-shaped mechanism. The bottom of the second connecting plate is connected to one end of the bottom support plate. Under the drive of the second drive component, the fourth drive component, and the fifth drive component, the support plate, the first connecting plate, and the second connecting plate can be moved respectively. Thus, when the clamp grips the module, the bottom support plate can be placed under the module; when the module is pressed into the battery pack, the bottom support plate can be removed from under the module.

[0034] To illustrate the specific structure of the fourth drive assembly, the present invention employs a fourth drive assembly comprising: a fourth cylinder, which is fixed to the end of the support plate, with its output end parallel to the width direction of the mounting plate; the top of the first connecting plate and the end of the support plate are slidably connected by a combination of a slider and a slide rail; the output end of the fourth cylinder is fixedly connected to the first connecting plate, and when the fourth cylinder is working, the first connecting plate moves linearly parallel to the width direction of the mounting plate;

[0035] The cylinder body of the horizontally positioned fourth cylinder is fixedly connected to the end of the support plate, and its output end is fixedly connected to the first connecting plate.

[0036] To illustrate the specific structure of the fifth drive assembly, the present invention employs a fifth drive assembly comprising: a fifth cylinder, which is vertically fixed on the first connecting plate, and its output end is fixedly connected to the second connecting plate; the first connecting plate and the second connecting plate are slidably connected by a combination of a slider and a slide rail; when the fifth cylinder is working, it drives the second connecting plate to move up and down relative to the first connecting plate;

[0037] In this design, the cylinder body of the vertically arranged fifth cylinder is fixedly connected to the first connecting plate, and its output end is fixedly connected to the second connecting plate.

[0038] In the process of pressing the module into the battery pack, the drive mechanism at the top of the conventional mounting base is rigidly connected to the mounting base. This requires very accurate positioning of the module during the pressing process. However, because the module and the gripper are positioned together, collisions can occur between the module and the inner wall of the battery pack. To avoid damage to the module due to rigid contact between the module and the battery pack during the pressing process, this invention also includes a frame. The bottom of the frame is connected to the mounting base via a floating assembly. The floating assembly includes: a floating plate, which is fixedly connected to the upper surface of the mounting base; multiple thrust ball bearings, which connect the bottom of the frame and the floating plate; and at least two limiting cylinders, which are inverted and fixed to the bottom side of the frame, with limiting parts at their output ends. When the limiting cylinders are working, their output ends, together with the limiting parts, are inserted into limiting holes on the floating plate to fix the frame and the floating plate.

[0039] The frame is part of the fixture that enables three-axis movement. The bottom of the frame is connected to the mounting base via a floating assembly, which includes a floating plate fixed to the mounting base. Multiple thrust ball bearings are installed between the floating plate and the frame. When the module collides with the inner wall of the battery pack, the thrust ball bearings are deflected by the force, which in turn causes the floating plate and the mounting base to shift, preventing a rigid collision between the module and the battery pack. In other words, the entire fixture will undergo two-axis planar movement under the influence of external forces. When the fixture does not require the floating assembly, the limit cylinder is activated and inserts its output end into the limit hole of the floating plate. At this time, the frame and the floating plate are positioned and connected, the thrust ball bearings are not activated, and the frame and the fixture move synchronously.

[0040] The limiting cylinder is preferably located diagonally on the subframe, and the limiting hole is also preferably located diagonally on the floating plate.

[0041] In order to position the battery pack, the present invention employs a positioning component provided on the side of the mounting base; the positioning component includes: a positioning frame, which is fixedly connected to the side of the mounting base; and a positioning camera, which moves along the length direction of the positioning frame via a sliding component.

[0042] The positioning camera is used to photograph and position the battery pack. The positioning camera is slidably mounted on the positioning frame, which is fixedly mounted on one side of the mounting base. The positioning camera can move linearly along the positioning frame under the drive of the drive component.

[0043] To enable the rotation of the mounting base, the present invention further includes: a vertical beam with a rotary motor fixed to its side, the bottom of the vertical beam being rotatably connected to the top of the frame; a slewing bearing with its outer ring fixedly connected to the top end face of the frame and its inner ring fixedly connected to the vertical beam; a gear that meshes with the outer ring of the slewing bearing is fixed to the output end of the rotary motor; when the rotary motor is working, the gear drives the outer ring of the slewing bearing to rotate, thereby driving the frame to rotate.

[0044] The bottom of the vertical beam is rotatably connected to the frame via a bearing. A slewing bearing is installed on the vertical beam. The inner ring of the slewing bearing is fixedly connected to the vertical beam, and the outer ring is fixedly connected to the frame. The slewing motor is fixed on the vertical beam, and a gear is fixed at the output end of the slewing motor. The gear meshes with the outer ring of the slewing bearing. When the slewing motor starts, it drives the outer ring of the slewing bearing to rotate, which in turn drives the frame to rotate.

[0045] In order to achieve the three-axis motion of this device, the present invention employs a motion module on the vertical beam to drive it to perform three-axis linear motion.

[0046] The motion module can drive a number of objects to perform three-axis linear motion.

[0047] The beneficial effects of this invention are as follows: This invention is a square power battery CTP module insertion fixture. Lateral clamping mechanisms are slidably mounted on the left and right sides of the mounting base, used to clamp the left and right sides of the module. End clamping mechanisms are slidably arranged on the front and rear sides of the mounting base, used to clamp the front and rear ends of the module. Thus, by clamping the module in the front-back and left-right directions, the module can be gripped from the workstation. When it is necessary to place the module into the battery pack, the first drive mechanism operates, and its extended end is connected to a quick-change mechanism. The quick-change mechanism acts on the upper surface of the module, reducing the clamping force of the end clamping mechanism and the lateral clamping mechanism on the module, and giving the module a downward pushing force, thus pressing the module into the housing. This improves the efficiency of the grippers in grasping the module and the efficiency of pressing the module into the battery pack. Attached Figure Description

Detailed Implementation

[0064] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0065] like Figure 1-2 As shown, the present invention is a square power battery CTP module loading fixture, comprising: a mounting base 1; two lateral clamping mechanisms 2, which are slidably disposed on both sides of the mounting base 1, the two lateral clamping mechanisms 2 being adapted to clamp the left and right sides of the module; two end clamping mechanisms 3, which are slidably disposed at both ends of the bottom of the mounting base 1 and are adapted to clamp the front and rear ends of the module; a quick-change mechanism 4, which is disposed below the mounting base 1; and a first drive mechanism 5, which is disposed on the mounting base 1, the protruding end of which is detachably connected to the quick-change mechanism 4 via a zero-point mechanism 46.

[0066] In this solution, lateral clamping mechanisms are slidably installed on the left and right sides of the mounting base. The lateral clamping mechanisms are used to clamp the left and right sides of the module. End clamping mechanisms are slidably installed on the front and rear sides of the mounting base. The end clamping mechanisms are used to clamp the front and rear ends of the module. In this way, the module can be clamped from the workstation by clamping the module in the front-back and left-right directions.

[0067] When the module needs to be placed into the battery pack, the first drive mechanism works, and its extended end is connected to the quick-change mechanism. The quick-change mechanism acts on the upper surface of the module. At this time, the clamping force of the end clamping mechanism and the side clamping mechanism on the module is reduced, and the module is given a downward pushing force to press the module into the box.

[0068] The first drive mechanism can be an electric cylinder, with its cylinder body inverted and mounted on the mounting base, and its output end passing through the mounting base and connected to a quick-change mechanism.

[0069] This fixture can not only realize the insertion of square power battery CTP modules into the box (battery pack), but also the insertion of modules with rectangular cross-sections into the box;

[0070] like Figure 14 As shown, in addition, different specifications of quick-change mechanisms can be replaced through the zero-point mechanism, and different specifications of quick-change mechanisms can realize the insertion of modules of different sizes into the box.

[0071] like Figure 2 As shown, in order to improve the module gripping efficiency, the present invention employs a suction cup 47 for adsorbing the module on the quick-change mechanism 4;

[0072] The suction cup can adhere to the upper surface of the module. When clamping the module, there is a clamping force exerted on the module by the lateral clamping mechanism and the end clamping mechanism, as well as the suction force of the suction cup on the module.

[0073] like Figure 3-4As shown, to illustrate the specific structure of the lateral clamping mechanism, the present invention employs the lateral clamping mechanism 2 comprising: an extension seat 6, which is connected to the side of the mounting seat 1; a sliding plate 7, which is slidably disposed at the bottom of the extension seat 6; a second driving assembly, which is adapted to drive the sliding plate 7 to move linearly along the extension seat 6; and a third driving assembly, which is fixed to the end face of the sliding plate 7, and whose output end is fixed with a clamping plate 8.

[0074] In this solution, a sliding plate is slidably provided at the bottom of the extension seat. Under the drive of the second drive component, the sliding plate moves closer to or away from the left and right sides of the module. A clamping plate is provided on the sliding plate. Under the drive of the third drive component, the clamping plate moves closer to or away from the sliding plate, that is, the clamping plate moves closer to or away from the left and right sides of the module. The clamping plate directly acts on the sides of the module.

[0075] In other words, the sliding plate performs a primary motion under the drive of the second drive component, and the clamping plate performs a secondary motion under the drive of the third drive component.

[0076] like Figure 1 , 3 As shown in Figure 6, in addition, an extension plate 9 is fixed on the sliding plate 7, and a trigger 23 is provided at the bottom of the second sliding plate 16. When the sliding plate 16 drives the extension plate 9 to move closer to the module and touches the trigger 23, the third drive component can then be activated to extend the clamping plate 8. This prevents the lateral clamping mechanism from being mispositioned, causing the sliding plate to be located outside the workstation. When the clamping plate extends, it acts on the side wall of the workstation, not the side wall of the module. In summary, the first-level movement of the sliding plate can indicate whether the clamping plate is located on the side of the module.

[0077] like Figure 3-4 As shown, in order to illustrate the specific structure of the second drive assembly, the present invention adopts the following second drive assembly: a motor 10, which is fixed on the extension seat 6; a lead screw 12, which is rotatably disposed at the bottom of the extension seat 6, one end of which is connected to the output end of the motor 10 through a sprocket 11; and a lead screw nut, which is fixed to the top of the sliding plate 7 and threadedly connected to the lead screw 12.

[0078] The motor is horizontally fixed on the extension base. The top of the sliding plate and the bottom of the extension base are slidably connected by a slider and a slide rail. The length of the slide rail is parallel to the length of the mounting base. The lead screw is installed at the bottom of the extension base and can rotate freely. The lead screw threadedly engages with the lead screw on the top of the sliding plate. The output end of the motor is connected to the end of the lead screw by a sprocket. When the motor rotates, the lead screw rotates, thereby realizing the translation of the lead screw nut on the lead screw, and thus the translation of the sliding plate.

[0079] like Figure 3-4As shown, to illustrate the specific structure of the third drive assembly, the present invention employs a third drive assembly comprising: two cylinders 13, the cylinder bodies of which are fixed on the sliding plate 7, and the two ends of the clamping plate 8 are respectively connected to the output ends of the cylinders 13; two guide rods 14, which pass through the sliding plate 7 and connect the ends of the two guide rods 14 to the clamping plate 8 respectively, and the other ends of the two guide rods 14 are connected to a connecting rod 15;

[0080] The cylinders are symmetrically fixed on the sliding plate. The two ends of the clamping plate are connected to the output ends of the cylinders respectively. The output ends of the cylinders extend out, driving the clamping plate away from the sliding plate. In order to ensure that the clamping plate remains horizontal during the extension process, two guide rods are provided on the clamping plate. The two guide rods pass through the sliding plate, and the two ends of the connecting rod are respectively connected to one end of the two guide rods.

[0081] like Figure 5-6 As shown, to illustrate the specific structure of the end clamping mechanism, the present invention employs an end clamping mechanism 3 comprising: a second sliding plate 16, which is slidably disposed at the bottom of the mounting base 1; a gripper 17, which is vertically connected to the second sliding plate 16; and a third driving mechanism, which is fixed on the mounting base 1, with its output end fixedly connected to the second sliding plate 16; when the third driving mechanism is working, it is adapted to drive the second sliding plate 16 together with the gripper 17 to move linearly along the length direction of the mounting base 1.

[0082] In this solution, the second sliding plate is slidably disposed at the bottom of the mounting base by a combination of slider and slide rail, and is adapted to move along the length direction of the mounting base. The gripper is vertically disposed at the bottom of the second sliding plate. The third drive mechanism works to drive the second sliding plate together with the gripper to move along the length direction of the mounting base until the gripper abuts against the end face of the module, thereby achieving clamping of the end of the gripper.

[0083] like Figure 5-6 As shown, in order to illustrate the specific structure of the third drive mechanism, the present invention uses a horizontally arranged electric cylinder 18 as the third drive mechanism;

[0084] The electric cylinder of the third drive mechanism is horizontally fixed on the mounting base, and the output end of the electric cylinder is fixedly connected to the seat on the second sliding plate.

[0085] like Figure 5-7 As shown, in order for the gripper to adapt to modules of different widths, the gripper needs to be replaced. To achieve the replacement of the gripper, the present invention provides a pin hole 19 on the top of the gripper 17; a pin part 20 with a second pin hole is provided on the top surface of the second sliding plate 16; a pin cylinder 21 is fixed on the end face of the second sliding plate 16, and a pin 22 is provided at its output end; when the pin cylinder 21 is working, the pin 21 passes through the pin hole 19 and the second pin hole in sequence, connecting the second sliding plate 16 and the gripper 17.

[0086] The pin hole at the top of the gripper passes through the second sliding plate, so that the pin hole and the pin hole of the pin part are concentric. The output end of the pin cylinder is connected to the pin. The pin passes through the second pin hole and the pin hole, and the gripper and the second sliding plate are inserted and connected, realizing the detachable connection of the gripper, which facilitates the replacement of grippers of different widths to adapt to modules of different widths.

[0087] like Figure 3-4 As shown, in order to prevent the module from falling during transportation, the present invention also adopts two bottom-supporting mechanisms 24, which are respectively fixedly connected to the side clamping mechanism 2. After the module is clamped, the bottom plate 25 of the bottom-supporting mechanism 24 is located below the module.

[0088] The bottom support mechanism is connected to the side clamping mechanism. The bottom plate of the bottom support mechanism is adapted to move to the bottom of the module. When the module falls, the two bottom plates of the two bottom support mechanisms will support the module.

[0089] like Figure 3-4 As shown, to illustrate the specific structure of the bottom-supporting mechanism, the present invention employs the following additional components: a support plate 26, which is parallel to the length direction of the mounting plate 1, and its middle portion is fixedly connected to the lateral clamping mechanism 2; a first connecting plate 27, which is disposed at the end of the support plate 26 and moves along the width direction of the mounting base 1 under the drive of the fourth driving component; a second connecting plate 28, which is slidably connected to the first connecting plate 27 and is raised and lowered by the drive frame of the fifth driving component; and the two ends of the bottom-supporting plate 25 are fixedly connected to the bottoms of the two second connecting plates 28.

[0090] The support plate is set parallel to the length direction of the mounting base and connected to the lateral clamping mechanism. Specifically, the middle part of the support plate is connected to the sliding plate. In this way, the support plate can be moved closer to or away from the mounting base under the drive of the second drive component. The top of the first connecting piece is slidably connected to the end of the support plate through a combination of slide rails and sliders. The first connecting plate moves along the width direction of the mounting base under the action of the fourth drive component. The second connecting plate is slidably connected to the first connecting plate through a combination of vertically set slide rails and sliders. Under the drive of the fifth drive component, the second connecting plate is raised and lowered. The second connecting plate has an L-shaped mechanism. The bottom of the second connecting plate is connected to one end of the bottom support plate. Under the drive of the second drive component, the fourth drive component, and the fifth drive component, the support plate, the first connecting plate, and the second connecting plate can be moved respectively. Thus, when the clamp grips the module, the bottom support plate can be placed under the module; when the module is pressed into the battery pack, the bottom support plate can be removed from under the module.

[0091] like Figure 3-4As shown, to illustrate the specific structure of the fourth drive assembly, the present invention employs a fourth drive assembly comprising: a fourth cylinder 29, which is fixed to the end of the support plate 26, with its output end parallel to the width direction of the mounting plate 1; the top of the first connecting plate 27 is slidably connected to the end of the support plate 26 via a combination of a slider and a slide rail; the output end of the fourth cylinder 29 is fixedly connected to the first connecting plate 27, and when the fourth cylinder 29 operates, the first connecting plate 27 moves linearly parallel to the width direction of the mounting plate 1;

[0092] The cylinder body of the horizontally positioned fourth cylinder is fixedly connected to the end of the support plate, and its output end is fixedly connected to the first connecting plate.

[0093] like Figure 3-4 As shown, to illustrate the specific structure of the fifth drive assembly, the present invention employs a fifth drive assembly comprising: a fifth cylinder 30, which is vertically fixed on the first connecting plate 27, and its output end is fixedly connected to the second connecting plate 28; the first connecting plate 27 and the second connecting plate 28 are slidably connected by a combination of a slider and a slide rail; when the fifth cylinder 30 is working, it drives the second connecting plate 28 to move up and down relative to the first connecting plate 27;

[0094] In this design, the cylinder body of the vertically arranged fifth cylinder is fixedly connected to the first connecting plate, and its output end is fixedly connected to the second connecting plate.

[0095] like Figure 10 As shown, during the process of pressing the module into the battery pack, the drive mechanism at the top of the conventional mounting base is rigidly connected to the mounting base. This requires the module to be positioned very accurately during the pressing process. However, during the pressing process, since the module and the gripper are positioned, the module may collide with the inner wall of the battery pack. To avoid damage to the module due to rigid contact between the module and the battery pack during the pressing process, this invention also includes a frame 31. The bottom of the frame 31 is connected to the mounting base 1 via a floating assembly. The floating assembly includes: a floating plate 32, which is fixedly connected to the upper surface of the mounting base 1; multiple thrust ball bearings 33, which connect the bottom of the frame 1 and the floating plate 32; and at least two limiting cylinders 34, which are inverted and fixed to the bottom side of the frame 31, with a limiting part at their output end. When the limiting cylinder 34 is working, its output end, together with the limiting part, is inserted into a limiting hole 35 on the floating plate 32 to fix the frame 31 and the floating plate 32.

[0096] The frame is part of the fixture that enables three-axis movement. The bottom of the frame is connected to the mounting base via a floating assembly, which includes a floating plate fixed to the mounting base. Multiple thrust ball bearings are installed between the floating plate and the frame. When the module collides with the inner wall of the battery pack, the thrust ball bearings are deflected by the force, which in turn causes the floating plate and the mounting base to shift, preventing a rigid collision between the module and the battery pack. In other words, the entire fixture will undergo two-axis planar movement under the influence of external forces. When the fixture does not require the floating assembly, the limit cylinder is activated and inserts its output end into the limit hole of the floating plate. At this time, the frame and the floating plate are positioned and connected, the thrust ball bearings are not activated, and the frame and the fixture move synchronously.

[0097] The limiting cylinder is preferably located diagonally on the subframe, and the limiting hole is also preferably located diagonally on the floating plate.

[0098] like Figure 8-9 As shown, in order to position the battery pack, the present invention employs a positioning component 36 provided on the side of the mounting base 1; the positioning component 36 includes: a positioning frame 37, which is fixedly connected to the side of the mounting base 1; and a positioning camera 38, which moves along the length direction of the positioning frame 37 via a sliding component.

[0099] The positioning camera is used to photograph and position the battery pack. The positioning camera is slidably mounted on the positioning frame, which is fixedly mounted on one side of the mounting base. The positioning camera can move linearly along the positioning frame under the drive of the drive component. The drive component can be achieved by using a motor to drive a lead screw to rotate, thereby driving the camera to move linearly.

[0100] like Figure 11 As shown, to achieve the rotation of the mounting base, the present invention further includes: a vertical beam 38, on which a rotary motor 39 is fixedly fixed; the bottom of the vertical beam 38 is rotatably connected to the top of the frame 31; a rotary bearing 41, the outer ring of which is fixedly connected to the top end face of the frame 31, and the inner ring of which is fixedly connected to the vertical beam 28; a gear 40 is fixedly fixed to the output end of the rotary motor 39, meshing with the outer ring of the rotary bearing 41; when the rotary motor 39 is working, the gear 40 drives the outer ring of the rotary bearing 41 to rotate, and drives the frame 31 to rotate.

[0101] The bottom of the vertical beam is rotatably connected to the frame via a bearing. A slewing bearing is installed on the vertical beam. The inner ring of the slewing bearing is fixedly connected to the vertical beam, and the outer ring is fixedly connected to the frame. The slewing motor is fixed on the vertical beam, and a gear is fixed at the output end of the slewing motor. The gear meshes with the outer ring of the slewing bearing. When the slewing motor starts, it drives the outer ring of the slewing bearing to rotate, which in turn drives the frame to rotate.

[0102] like Figure 11-13As shown, in order to realize the three-axis motion of this device, the present invention uses a motion module 42 on the vertical beam 38 to drive it to perform three-axis linear motion.

[0103] The motion module can drive a number of objects to perform three-axis linear motion;

[0104] Specifically, in the figure, the cylinder body of the lifting electric cylinder 43 is fixedly mounted with a tripod 44, the extended end of which is fixedly connected to the vertical beam 38. Tripods 44 are also provided on both sides of the vertical beam 38. The tripods 44 on both sides are used to fix the locking cylinder 45. The output end of the locking cylinder 45 is connected to the vertical beam 38. In this way, when the lifting electric cylinder 43 malfunctions and causes the vertical beam 38 to fall, the locking cylinder 45 will work in time to prevent the vertical beam 38 from falling further. In other words, the locking cylinder 45 plays a safety role.

[0105] In summary, the previous module product 1.0 was a combination of standard modules such as VDA and MEB; the current product update 2.0 is represented by the CTP-S module-less design, where the cells are directly inserted into the PACK box (within the same box area, more cells can be placed than before, resulting in a larger battery capacity, and the production process and accessories are greatly simplified, but at the same time, the production difficulty is increased).

[0106] Previously, several machines were needed to perform the box-loading function, but now only one machine is needed. Depending on the length and width of the product, automatic switching is achieved without human intervention, including an automatic quick-change mechanism, to meet production needs.

[0107] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
