[0003] The present application relates to the field of battery technology, and in particular to an assembly device and assembly method, and battery processing equipment. Background Art

[0004] During the battery manufacturing process, the wiring harness plate needs to be assembled onto the battery to form an integrated structure. Currently, the wiring harness plate assembly process is not only inefficient but also has low assembly precision, which affects the overall production efficiency of the battery.

[0005] Summary of the Invention

[0006] Based on this, the present application provides an assembly device and assembly method, and battery processing equipment.

[0007] In a first aspect, the present application provides an assembly device for assembling a wiring harness plate onto a battery, the assembly device comprising:

[0008] A carrying platform, comprising a carrying surface for carrying the wiring harness plate, the carrying surface having a gripping position;

[0009] A first positioning mechanism is movably provided on the carrier platform and is used to position the wiring harness plate at a grabbing position;

[0010] a second positioning mechanism, disposed on one side of the carrier, and configured to detect the current position of the battery and assemble the wiring harness plate on the gripping position to the battery according to a deviation value between the current position and the target position; and

[0011] A conveying mechanism is provided on one side of the carrying platform and is used to convey the wiring harness plate. The conveying mechanism includes a conveying member and a lifting assembly. The conveying member is used to convey the wiring harness plate, and the lifting assembly is used to lift the wiring harness plate on the conveying member. The lifting assembly includes a tray for carrying the wiring harness plate. A third positioning member is protruding from a surface of the tray facing the wiring harness plate. The third positioning member is used to be inserted into a positioning hole on the wiring harness plate to position the wiring harness plate during the lifting process.

[0012] The second positioning mechanism is further configured to move the wiring harness plate from the conveying mechanism to the carrying surface.

[0013] Through this structure, the first positioning mechanism can position the wiring harness plate at the grabbing position on the support surface, achieving the first positioning during the assembly process. The second positioning mechanism then detects the current position of the battery and compares the deviation between the current battery position and the target position. At this point, the second positioning mechanism grabs the wiring harness plate from the grabbing position and moves it. During this movement, the assembly position between the wiring harness plate and the battery is compensated based on the deviation, achieving the second positioning during the assembly process. Ultimately, these two positioning operations improve the assembly accuracy and efficiency between the wiring harness plate and the battery.

[0014] In some embodiments, the first positioning mechanism includes a first positioning member and a second positioning member both disposed on the supporting platform, the first positioning member and the second positioning member enclosing to form a gripping position;

[0015] The first positioning member is movably arranged along the first direction and is used to drive the wiring harness plate to move along the first direction; the second positioning member is movably arranged along the second direction and is used to drive the wiring harness plate to move along the second direction;

[0016] The first direction intersects with the second direction and both are parallel to the bearing surface.

[0017] By providing a first positioning member and a second positioning member, the wiring harness plate can be driven to move in the first direction and the second direction, respectively, thereby positioning the wiring harness plate at the gripping position. When the second positioning mechanism grips the wiring harness plate, the wiring harness plate can be connected to the designated position on the second positioning mechanism. This reduces the positional offset between the wiring harness plate and the battery during the subsequent assembly process of the wiring harness plate onto the battery by the second positioning mechanism, thereby improving assembly accuracy.

[0018] In some embodiments, the second positioning mechanism includes a moving part and a clamp disposed on the moving part, the clamp is used to clamp the wiring harness plate, and the moving part is used to drive the clamp and the wiring harness plate thereon to move.

[0019] Through the above structure, the wiring harness plate can be grasped and moved, thereby realizing automatic assembly between the wiring harness plate and the battery, thereby improving assembly efficiency.

[0020] In some embodiments, the clamp includes a main body, a suction cup disposed on the main body, and a vacuum generator, wherein the vacuum generator is used to form negative pressure inside the suction cup, and the suction cup is used to suck the wiring harness plate.

[0021] Through the cooperation of the suction cup and the vacuum generator, the wiring harness plate can be smoothly grasped and then driven to move. By breaking the vacuum of the vacuum generator, the suction cup and the wiring harness plate can be quickly separated, thereby completing the placement of the wiring harness plate on the battery.

[0022] In some embodiments, the second positioning mechanism further includes a distance meter disposed on the fixture, and the distance meter is used to measure the distance between the fixture and the wiring harness plate.

[0023] By setting up a distance meter, the distance between the fixture and the wiring harness plate can be accurately measured, which not only enables the suction cup to adsorb the wiring harness plate more quickly, but also makes the suction cup's adsorption of the wiring harness plate more stable.

[0024] In some embodiments, the second positioning mechanism further includes a detection member disposed on the fixture, and the detection member is used to detect a deviation value between the current position of the battery and the target position.

[0025] By setting up a detection part, the deviation value between the current position of the battery and the target position can be detected, so that the second positioning mechanism can compensate for the above deviation value in the process of driving the wiring harness plate toward the battery, thereby making the assembly between the wiring harness plate and the battery more accurate.

[0026] In some embodiments, the assembly device further includes a control component, which is communicatively connected to the detection component and the moving component, and is used to control the movement of the moving component according to the deviation value.

[0027] By setting up the control components, automatic control can be achieved, thereby realizing the automatic movement and automatic assembly process of the wiring harness board and improving the assembly efficiency.

[0028] In some embodiments, the lifting assembly includes a driving member and a lifting member, the lifting member having an inclined surface and a supporting surface, the inclined surface is inclined along the vertical direction, and the supporting surface is horizontally arranged and connected to the top of the inclined surface;

[0029] The driving component is used to drive the wiring harness plate to climb from the inclined surface to the supporting surface.

[0030] By providing a driving member and a lifting member, the wiring harness plate can be moved from the conveyor belt to the support surface, thereby removing the wiring harness plate from the conveyor belt and achieving the wiring harness plate's grip and movement without affecting the continued conveyance of the conveyor belt. In addition, the lifting member cooperates with the driving member through the inclined surface and the support surface to achieve the vertical lifting of the wiring harness plate, which can save vertical installation space and make the overall structure of the assembly device more compact, taking up less space.

[0031] In some embodiments, the third positioning member is retractably arranged on the tray along its protruding direction. Through the above structure, the third positioning member can be more flexibly controlled to be inserted into or removed from the positioning hole, thereby realizing the plug-in and separation between the tray and the wiring harness plate.

[0032] In a second aspect, the present application provides a battery processing device, comprising the assembly device as described above, the assembly device being used to assemble a wiring harness plate onto a battery.

[0033] In a third aspect, the present application provides an assembly method, comprising the following steps:

[0040] Grab the wiring harness board on the grabbing position and control the movement of the wiring harness board according to the deviation value to compensate for the offset between the battery and the wiring harness board;

[0041] Assemble the wiring harness plate to the battery.

[0042] In some embodiments, the step of positioning the wiring harness plate to a grabbing position of the load-bearing surface specifically includes:

[0043] Controlling the first positioning member to drive the wiring harness plate to move along the first direction;

[0044] The second positioning member is controlled to drive the wiring harness plate to move along the second direction to position the wiring harness plate to the grabbing position; wherein the first direction intersects with the second direction and is parallel to the bearing surface.

[0045] In some embodiments, the step of grabbing the wiring harness plate on the grabbing position and controlling the movement of the wiring harness plate according to the deviation value to compensate for the offset between the battery and the wiring harness plate specifically includes:

[0046] Control the suction cup to move to the top of the wiring harness plate;

[0047] Measure the distance between the suction cup and the harness plate;

[0048] Control the suction cup to move toward the wiring harness plate so that the suction cup contacts the wiring harness plate;

[0049] Control the suction cup to absorb the wiring harness board;

[0050] Obtain the negative pressure data inside the suction cup and determine whether the suction cup and the wiring harness board are adsorbed according to the negative pressure data;

[0051] If adsorption is completed, the control harness board moves to just above the battery;

[0052] The movement of the harness plate is controlled according to the deviation value to compensate for the offset between the battery and the harness plate.

[0053] In some embodiments, the step of assembling the wiring harness plate to the battery specifically includes:

[0054] Separate the control suction cup from the wiring harness plate to place the wiring harness plate on the battery;

[0055] Control the suction cup to move away from the wiring harness plate.

[0056] The above-mentioned assembly device and assembly method, and battery processing equipment place the wiring harness plate on the supporting surface, and can first perform a first positioning of the wiring harness plate through the first positioning mechanism so that it is positioned at the grasping position, and then perform a second positioning of the current position of the battery through the second positioning mechanism, and detect the deviation value between the current position of the battery and the target position through the second positioning mechanism, and compensate the assembly position between the wiring harness plate and the battery according to the deviation value; thus, after two positionings, the wiring harness plate can be more accurately positioned at the installation position of the battery, thereby improving the assembly accuracy and assembly efficiency between the wiring harness plate and the battery.

[0072] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in other fields. As the application of power batteries continues to expand, market demand is also growing.

[0073] A battery cell is the smallest unit that makes up a battery. After one or more battery cells are assembled to form a battery, each battery cell needs to be connected through a wire. A wiring harness plate is needed between the wires to neatly arrange and store them, making the internal structure of the battery more regular and facilitating assembly or maintenance of the battery.

[0074] After the wires are stored in the wiring harness, they are typically secured to the outside of the battery housing to form a cohesive battery structure. However, the current assembly of the wiring harness and battery is often done manually, requiring the wiring harness to be manually lifted and placed in the designated location on the battery before being securely connected to the battery.

[0075] During this process, manual operation has the problems of low operating accuracy and low operating efficiency. In addition, since the wiring harness board is used to store wires, there are safety issues during manual operation. Once an operation error occurs, it is easy to cause a short circuit in the wiring harness board.

[0076] Based on the above considerations, in order to solve the current problem of low operating efficiency and assembly accuracy during the assembly process of the wiring harness plate and the battery, one or more embodiments of the present application provide an assembly device. The wiring harness plate is placed on a supporting surface. The wiring harness plate can be first positioned by a first positioning mechanism to position it at the grabbing position. Then, the current position of the battery is positioned for a second time by a second positioning mechanism. The deviation between the current position of the battery and the target position is detected by the second positioning mechanism, and the assembly position between the wiring harness plate and the battery is compensated according to the deviation. Thus, after two positionings, the wiring harness plate can be more accurately positioned at the installation position of the battery, thereby improving the assembly accuracy and efficiency between the wiring harness plate and the battery.

[0077] Referring to Figures 1, 2, and 3, an embodiment of the present application provides an assembly device 100 for assembling a wiring harness plate 200 onto a battery 300. The assembly device 100 includes a carrier 10, a first positioning mechanism 20, and a second positioning mechanism 30. The carrier 10 includes a carrier surface 11 for supporting the wiring harness plate 200, and the carrier surface 11 has a gripping position 12. The first positioning mechanism 20 is movably disposed on the carrier 10 and is used to position the wiring harness plate 200 at the gripping position 12. The second positioning mechanism 30 is disposed on one side of the carrier 10 and is configured to detect the current position of the battery 300 and, based on a deviation between the current position and a target position, assemble the wiring harness plate 200 at the gripping position 12 onto the battery 300.

[0078] It should be noted that the support platform 10 is a structure that can provide a support base for the wiring harness plate 200 and a mounting base for the first positioning mechanism 20 and the second positioning mechanism 30. The support surface 11 can be set as the top surface of the support platform 10 and is arranged horizontally to facilitate the placement of the wiring harness plate 200.

[0079] The carrying surface 11 has a grabbing position 12 , and the first positioning mechanism 20 can move relative to the carrying platform 10 and drive the wiring harness plate 200 on the carrying surface 11 to move synchronously during the movement, thereby positioning the wiring harness plate 200 on the grabbing position 12 .

[0080] Furthermore, in order to facilitate the assembly between the wiring harness plate 200 and the battery 300, the battery 300 can be placed on the same side of the carrier 10 and the second positioning mechanism 30. Specifically, the battery 300 can be placed on the conveyor 41 or on the material trolley, and ultimately placed on the same side of the carrier 10 and the second positioning mechanism 30.

[0081] The second positioning mechanism 30 first detects the current position of the battery 300. Before that, a target position is preset. That is, after the second positioning mechanism 30 grabs the wiring harness plate 200 from the grabbing position 12, the wiring harness plate 200 and the battery 300 are assembled at the target position.

[0082] However, in actual operation, there is usually a certain deviation between the current position of the battery 300 and the target position. Therefore, the current position of the battery 300 is first detected by the second positioning mechanism 30, and then the current position is compared with the target position to obtain the deviation value between the two.

[0083] Furthermore, after the second positioning mechanism 30 grabs the wiring harness plate 200 from the grabbing position 12, it moves the wiring harness plate 200 toward the battery 300, compensating for the aforementioned deviation during the movement. After compensation, the second positioning mechanism 30 assembles the wiring harness plate 200 onto the battery 300, thereby compensating for the error caused by the current positional deviation of the battery 300 and ensuring a more precise assembly between the wiring harness plate 200 and the battery 300.

[0084] In addition, after placing the wiring harness plate 200 on the supporting surface 11, the wiring harness plate 200 is moved by the first positioning mechanism 20 to position the wiring harness plate 200 at the grabbing position 12, which can also improve the subsequent assembly accuracy between the wiring harness plate 200 and the battery 300.

[0085] Specifically, if the initial positions of the wiring harness plates 200 are inconsistent, there will be varying degrees of offset between the wiring harness plates 200 and the second positioning mechanism 30 when the second positioning mechanism 30 grasps the wiring harness plates 200. In this case, when the second positioning mechanism 30 assembles the wiring harness plates 200 onto the battery 300, the accumulated offsets from the two steps will further increase the assembly error between the wiring harness plates 200 and the battery 300.

[0086] Therefore, through the above structure, the first positioning mechanism 20 can position the wiring harness plate 200 at the grabbing position 12 on the bearing surface 11, that is, realize the first positioning in the assembly process. Then, the second positioning mechanism 30 detects the current position of the battery 300 and compares the deviation value between the current position of the battery 300 and the target position. At this time, the second positioning mechanism 30 grabs the wiring harness plate 200 from the grabbing position 12 and drives the wiring harness plate 200 to move. During the movement, the assembly position between the wiring harness plate 200 and the battery 300 can be compensated according to the above deviation value, thereby realizing the second positioning in the assembly process. Ultimately, through two positioning, the assembly accuracy and efficiency between the wiring harness plate 200 and the battery 300 are improved.

[0087] In some embodiments, the first positioning mechanism 20 includes a first positioning member 21 and a second positioning member 22, both disposed on the support platform 10. The first positioning member 21 and the second positioning member 22 together form the gripping position 12. The first positioning member 21 is movable along a first direction a and is used to drive the wiring harness plate 200 along the first direction a. The second positioning member 22 is movable along a second direction b and is used to drive the wiring harness plate 200 along the second direction b. The first direction a and the second direction b intersect and are both parallel to the support surface 11.

[0088] Specifically, the first direction a and the second direction b are both arranged parallel to the supporting surface 11, and the first direction a and the second direction b are perpendicular to each other. The first positioning member 21 can be, but is not limited to, a first driving cylinder, and the second positioning member 22 can be, but is not limited to, a second driving cylinder. The gripping position 12 is formed between the first and second driving cylinders.

[0089] When the wiring harness plate 200 is placed on the supporting surface 11, the first drive cylinder telescopes in the first direction a, thereby driving the wiring harness plate 200 in the first direction a. The second drive cylinder telescopes in the second direction b, thereby driving the wiring harness plate 200 in the second direction b. Thus, through the cooperation of the first and second drive cylinders, the wiring harness plate 200 is positioned at the grabbing position 12.

[0090] By providing the first positioning member 21 and the second positioning member 22, the wiring harness plate 200 can be driven to move in the first direction a and the second direction b, respectively, thereby positioning the wiring harness plate 200 on the grabbing position 12. When the second positioning mechanism 30 grabs the wiring harness plate 200, the wiring harness plate 200 can be connected to the designated position on the second positioning mechanism 30. Therefore, when the second positioning mechanism 30 subsequently assembles the wiring harness plate 200 onto the battery 300, the positional offset between the wiring harness plate 200 and the battery 300 is reduced, thereby improving assembly accuracy.

[0091] Please refer to Figures 1, 4 and 5. In some embodiments, the second positioning mechanism 30 includes a moving part 31 and a clamp 32 arranged on the moving part 31. The clamp 32 is used to clamp the wiring harness plate 200, and the moving part 31 is used to drive the clamp 32 and the wiring harness plate 200 thereon to move.

[0092] Specifically, the moving part 31 can be, but is not limited to, a robotic arm or a handling robot, and the clamp 32 can grasp the wiring harness plate 200. The clamp 32 is set on the moving part 31, and the wiring harness plate 200 is first grasped by the clamp 32, and then the moving part 31 drives the clamp 32 and the wiring harness plate 200 thereon to move synchronously.

[0093] Through the above structure, the wiring harness plate 200 can be grasped and moved, thereby realizing automatic assembly between the wiring harness plate 200 and the battery 300, thereby improving assembly efficiency.

[0094] In some embodiments, the clamp 32 includes a main body 321 , a suction cup 322 disposed on the main body 321 , and a vacuum generator 323 . The vacuum generator 323 is used to form negative pressure inside the suction cup 322 , and the suction cup 322 is used to suck the wiring harness plate 200 .

[0095] Specifically, the main body 321 primarily serves to provide a mounting base for the suction cups 322 and vacuum generator 323. Multiple suction cups 322 can be provided to increase the suction area between the suction cups 322 and the wiring harness plate 200. The vacuum generator 323 is connected to all suction cups 322. When the wiring harness plate 200 is attracted, the suction cups 322 are first brought into contact with the plate 200. The vacuum generator 323 is then activated to create negative pressure within the suction cups 322, allowing the suction cups 322 to attract the plate 200. At this point, the movable member 31 can drive the fixture 32 and the wiring harness plate 200 to move synchronously.

[0096] After the moving part 31 drives the wiring harness plate 200 to complete the moving process, for example, when the wiring harness plate 200 is moved to the battery 300, the vacuum generator 323 is controlled to complete the vacuum breaking. At this time, the negative pressure state inside the suction cup 322 becomes a normal pressure state, and the wiring harness plate 200 can automatically fall off from the suction cup 322, thereby realizing the separation between the wiring harness plate 200 and the clamp 32.

[0097] Through the cooperation of the suction cup 322 and the vacuum generator 323, the wiring harness plate 200 can be smoothly grasped, and then the wiring harness plate 200 can be driven to move, and through the vacuum breaking of the vacuum generator 323, the suction cup 322 and the wiring harness plate 200 can be quickly separated, thereby completing the placement of the wiring harness plate 200 on the battery 300.

[0098] In some embodiments, the second positioning mechanism 30 further includes a distance meter 33 disposed on the fixture 32 , and the distance meter 33 is used to measure the distance between the fixture 32 and the wiring harness plate 200 .

[0099] Specifically, when the wiring harness plate 200 is positioned at the grabbing position 12, the second positioning mechanism 30 first moves the clamp 32 to the top of the wiring harness plate 200 via the moving member 31 during the process of grabbing the wiring harness plate 200. At this point, the distance meter 33 is activated to measure the vertical distance between the clamp 32 and the wiring harness plate 200. The actual distance measured by the second positioning mechanism 30 is then compared with the preset target distance. The moving member 31 then moves the clamp 32 based on the comparison result, so that the suction cup 322 is in contact with the upper surface of the wiring harness plate 200.

[0100] At this time, the vacuum generator 323 is activated to form a negative pressure inside the suction cup 322 , thereby completing the adsorption of the wiring harness plate 200 .

[0101] In addition, during the process of the suction cup 322 adsorbing the wiring harness plate 200, the second positioning mechanism 30 can also judge the adsorption state between the suction cup 322 and the wiring harness plate 200 based on the negative pressure data fed back by the vacuum generator 323, ensuring that the suction cup 322 has completed adsorbing the wiring harness plate 200, so as to make the adsorption and movement process of the wiring harness plate 200 more stable.

[0102] By providing the distance meter 33 , the distance between the fixture 32 and the wiring harness plate 200 can be accurately measured, which not only enables the suction cup 322 to adsorb the wiring harness plate 200 more quickly, but also makes the adsorption of the wiring harness plate 200 by the suction cup 322 more stable.

[0103] In some embodiments, the second positioning mechanism 30 further includes a detection member 34 disposed on the fixture 32 , and the detection member 34 is used to detect a deviation between the current position of the battery 300 and the target position.

[0104] Specifically, the detection member 34 may include a visual camera, which is disposed on the main body 321. The moving member 31 first drives the clamp 32 to move directly above the battery 300. The visual camera detects the current position of the battery 300 and then compares the current position with the target position to obtain a deviation value between the two.

[0105] Therefore, after the suction cup 322 absorbs the wiring harness plate 200 on the grabbing position 12, the moving part 31 drives the wiring harness plate 200 to move, and the moving position of the wiring harness plate 200 can be compensated according to the deviation value between the current position and the target position detected by the visual camera to compensate for the deviation value of the wiring harness plate 200 when assembled to the battery 300, thereby making the assembly between the wiring harness plate 200 and the battery 300 more precise.

[0106] By setting up the detection part 34, the deviation value between the current position of the battery 300 and the target position can be detected, so that the second positioning mechanism 30 can compensate for the above deviation value in the process of driving the wiring harness plate 200 to move toward the battery 300, thereby making the assembly between the wiring harness plate 200 and the battery 300 more precise.

[0107] In some embodiments, the assembly device 100 further includes a control component (not shown in the figure), which is communicatively connected to the detection member 34 and the moving member 31 respectively, and is used to control the movement of the moving member 31 according to the deviation value.

[0108] Specifically, the control assembly can be configured as a controller, which is communicatively connected to the visual camera and the moving member 31. After the visual camera detects the current position of the battery 300, it transmits this information to the controller. The controller compares the current position with the target position and determines the deviation between the two. The controller then controls the moving member 31 to compensate for this deviation, thereby ensuring a more accurate final assembly position between the wiring harness plate 200 and the battery 300.

[0109] Furthermore, the controller can also be connected to the rangefinder 33 for communication. After the rangefinder 33 measures the distance between the clamp 32 and the wiring harness plate 200, the distance data is transmitted to the controller. The controller compares the data with the preset distance, and then controls the movement of the movable part 31 according to the comparison result, so that the suction cup 322 can better fit between the wiring harness plate 200.

[0110] The controller can then communicate with the vacuum generator 323 and control the vacuum generator 323 to turn it on or off. When turned on, the vacuum generator 323 creates a negative pressure state inside the suction cup 322, allowing the suction cup 322 to adsorb the wiring harness plate 200. When turned off, the vacuum generator 323 breaks the vacuum, and the negative pressure inside the suction cup 322 is converted to a normal pressure state, allowing the suction cup 322 to separate from the wiring harness plate 200.

[0111] By setting up the control component, automatic control can be achieved, thereby realizing the automatic movement and automatic assembly process of the wiring harness plate 200, thereby improving the assembly efficiency.

[0112] In some embodiments, the assembly device 100 further includes a conveying mechanism 40 disposed on one side of the carrier 10 and configured to convey the wiring harness plate 200. The second positioning mechanism 30 is further configured to move the wiring harness plate 200 from the conveying mechanism 40 to the carrier surface 11.

[0113] Specifically, the conveying mechanism 40 is arranged on the same side of the second positioning mechanism 30 and the supporting platform 10, and can be used to convey multiple wiring harness plates 200. The second positioning mechanism 30 can grab the wiring harness plate 200 from the conveying mechanism 40, and then drive the wiring harness plate 200 to move and place the wiring harness plate 200 on the supporting surface 11 of the supporting platform 10.

[0114] By providing the conveying mechanism 40 , a plurality of harness plates 200 can be driven to move simultaneously, and at the same time, the harness plates 200 are grasped by the second positioning mechanism 30 , thereby improving assembly efficiency.

[0115] Please refer to FIG. 1 and FIG. 6 . In some embodiments, the conveying mechanism 40 includes a conveying member 41 and a lifting assembly 42 . The conveying member 41 is used to convey the wiring harness plate 200 , and the lifting assembly 42 is used to lift the wiring harness plate 200 on the conveying member 41 .

[0116] Specifically, the conveying member 41 can be set as a conveyor belt, and multiple wiring harness plates 200 are placed on the conveyor belt in sequence, and the conveyor belt drives the wiring harness plates 200 to move. The lifting assembly 42 can be set on one side of the conveyor belt in a direction intersecting with the conveying direction of the conveyor belt. When one of the wiring harness plates 200 moves to a specified position under the drive of the conveyor belt, the lifting assembly 42 lifts the wiring harness plate 200 upward from the conveyor belt to a certain height, so that the wiring harness plate 200 is separated from the conveyor belt, so that the second positioning mechanism 30 can grab the wiring harness plate 200 and place it on the carrying surface 11.

[0117] By setting up a conveying member 41 and a lifting assembly 42, the synchronous conveyance of multiple wiring harness plates 200 can be achieved, and the wiring harness plate 200 can be separated from the conveying member 41 by lifting, so that the second positioning mechanism 30 can grab the wiring harness plate 200 without affecting the continued conveyance of other wiring harness plates 200, thereby further improving the production efficiency of the battery 300.

[0118] In some embodiments, the lifting assembly 42 includes a driving member 421 and a lifting member 422. The lifting member 422 has an inclined surface 423 and a support surface 424. The inclined surface 423 is inclined in the vertical direction, and the support surface 424 is horizontally arranged and connected to the top of the inclined surface 423. The driving member 421 is used to drive the wiring harness plate 200 to climb from the inclined surface 423 to the support surface 424.

[0119] Specifically, the driving member 421 can be configured as a driving cylinder and can be movably configured in the horizontal direction. Thus, the driving member 421 can push the harness plate 200 on the conveyor belt onto the lifting member 422 in the horizontal direction.

[0120] Furthermore, the driving member 421 pushes the wiring harness plate 200 on the conveyor belt onto the inclined surface 423 in the horizontal direction, and then continues to push the wiring harness plate 200 along the inclined surface 423, so that the wiring harness plate 200 can move upward along the inclined surface 423 until the wiring harness plate 200 moves to the horizontally arranged support surface 424 and is fixed on the support surface 424.

[0121] As a result, the driving member 421 pushes the wiring harness plate 200 on the conveyor belt onto the inclined surface 423 in the horizontal direction, and pushes the wiring harness plate 200 to climb along the inclined surface 423 to the support surface 424. Then, the second positioning mechanism 30 grabs the wiring harness plate 200 from the support surface 424 and places the wiring harness plate 200 on the carrying surface 11.

[0122] By providing the driving member 421 and the lifting member 422, the wiring harness plate 200 can be moved from the conveyor belt to the support surface 424, thereby separating the wiring harness plate 200 from the conveyor belt and achieving the gripping and movement of the wiring harness plate 200 without affecting the continued conveyance of the conveyor belt. In addition, the lifting member 422 cooperates with the driving member 421 via the inclined surface 423 and the support surface 424 to achieve the vertical lifting of the wiring harness plate 200, which can save vertical installation space and make the overall structure of the assembly device 100 more compact, occupying less space.

[0123] In some embodiments, the lifting assembly 42 also includes a tray 425 for supporting the wiring harness plate 200. A third positioning member 426 is protruding from the side surface of the tray 425 facing the wiring harness plate 200. The third positioning member 426 is used to be inserted into the positioning hole on the wiring harness plate 200 to position it during the lifting process of the wiring harness plate 200.

[0124] Specifically, a third positioning member 426 is protruding from the top surface of the tray 425 . The third positioning member 426 can be, but is not limited to, a latch. A positioning hole that cooperates with the latch is provided on the bottom surface of the wiring harness plate 200 .

[0125] Before the driver 421 drives the wiring harness plate 200 to lift, the latch on the tray 425 is first inserted into the positioning hole of the wiring harness plate 200, so that the tray 425 and the wiring harness plate 200 are plugged and matched, and the two can be stably connected. Then, the driver 421 is controlled to push the tray 425 and the wiring harness plate 200 to climb along the inclined surface 423 to the support surface 424, and finally fixed on the support surface 424.

[0126] Therefore, during the lifting process of the wiring harness plate 200, the wiring harness plate 200 can be supported on the tray 425 through the plug-in cooperation between the third positioning member 426 and the positioning hole, making the wiring harness plate 200 more stable during the lifting process.

[0127] In some embodiments, the third positioning member 426 is telescopically disposed on the tray 425 along its protruding direction.

[0128] Specifically, the latch is retractably mounted on the tray 425 in a vertical direction. Prior to insertion, the latch is retracted. Before lifting the wiring harness plate 200, the latch is extended upward to allow it to be smoothly inserted into the positioning hole on the wiring harness plate 200, thereby completing the insertion and insertion between the two.

[0129] Through the above structure, the third positioning member 426 can be more flexibly controlled to be inserted into or removed from the positioning hole, thereby realizing the plug-in connection and separation between the tray 425 and the wiring harness plate 200.

[0130] Based on the same concept as the above-mentioned assembly device 100 , the present application also provides a battery 300 processing device, including the above-mentioned assembly device 100 , which is used to assemble the wiring harness plate 200 onto the battery 300 .

[0131] As shown in FIG7 , based on the same concept as the above-mentioned assembly device 100 , the present application also provides an assembly method, comprising the following steps:

[0132] S30 : Positioning the wiring harness plate 200 to the grabbing position 12 of the carrying surface 11 .

[0133] Specifically, the first positioning mechanism 20 is controlled to move the wiring harness plate 200 on the carrying surface 11 so as to position the wiring harness plate 200 in the grabbing position 12 on the carrying surface 11 , so as to facilitate the subsequent grabbing and positioning of the wiring harness plate 200 .

[0134] S40: Detect the current position of the battery 300 and compare it with the target position to obtain a deviation value between the two.

[0135] In order to make the assembly position between the wiring harness plate 200 and the battery 300 more accurate, it is usually necessary to position the battery 300 at a target position. However, in actual operation, there is usually a deviation, resulting in a certain offset between the current position of the battery 300 and the target position.

[0136] The current position of the battery 300 can be detected by a visual camera in the second positioning mechanism 30 , and the current position is compared with the target position to obtain a deviation value therebetween, which is the actual offset of the battery 300 .

[0137] S50 : Grab the wiring harness plate 200 on the grabbing position 12 , and drive the wiring harness plate 200 to move according to the deviation value to compensate for the offset between the battery 300 and the wiring harness plate 200 .

[0138] The clamp 32 in the second positioning mechanism 30 is controlled to grab the wiring harness plate 200 from the grabbing position 12, and the clamp 32 and the wiring harness plate 200 are driven to move synchronously via the moving member 31. During the movement process, the second positioning mechanism 30 drives the wiring harness plate 200 to move a corresponding distance based on the deviation between the current position of the battery 300 and the target position, thereby compensating for the actual offset of the battery 300 and ensuring a more accurate assembly position between the wiring harness plate 200 and the battery 300.

[0139] S60 : Assembling the harness plate 200 to the battery 300 .

[0140] After the final position of the wiring harness plate 200 is determined, the second positioning mechanism 30 is controlled to place the wiring harness plate 200 on the battery 300 , so as to complete the assembly between the wiring harness plate 200 and the battery 300 .

[0141] In some embodiments, step S30 specifically includes:

[0142] S31: Control the first positioning member 21 to drive the wiring harness plate 200 to move along the first direction a.

[0143] S32 : Control the second positioning member 22 to drive the wiring harness plate 200 to move along the second direction b, so as to position the wiring harness plate 200 to the grabbing position 12 ; wherein the first direction a and the second direction b intersect and are both parallel to the bearing surface 11 .

[0144] Specifically, the first direction a and the second direction b are both horizontal directions, and are perpendicular to each other.

[0145] The first positioning member 21 can be configured as a first driving cylinder, which drives the wiring harness plate 200 to move in the first direction a. The second positioning member 22 can be configured as a second driving cylinder, which drives the wiring harness plate 200 to move in the second direction b. Thus, through the cooperation of the first and second driving cylinders, the wiring harness plate 200 is positioned at the grabbing position 12.

[0146] The first positioning member 21 and the second positioning member 22 cooperate to move the wiring harness plate 200 in the first direction a and the second direction b, respectively, thereby positioning the wiring harness plate 200 on the grabbing position 12. When the second positioning mechanism 30 grabs the wiring harness plate 200, the wiring harness plate 200 is connected to the designated position on the second positioning mechanism 30. This reduces the positional offset between the wiring harness plate 200 and the battery 300 during the subsequent assembly of the wiring harness plate 200 onto the battery 300 by the second positioning mechanism 30, thereby improving assembly accuracy.

[0147] In some embodiments, step S50 specifically includes:

[0148] S51 : Control the suction cup 322 to move to just above the harness plate 200 .

[0149] Specifically, the second positioning mechanism 30 is driven by the moving member 31 to move the suction cup 322, wherein the moving member 31 can be, but is not limited to, a robotic arm or a handling robot. The suction cup 322 is provided on the main body 321 of the fixture 32, and multiple suction cups 322 can be provided to increase the suction area between the wiring harness plate 200 and improve suction stability.

[0150] S52 : Measure the distance between the suction cup 322 and the harness plate 200 .

[0151] Specifically, when the wiring harness plate 200 is positioned on the gripping position 12, the moving member 31 first drives the suction cup 322 to move directly above the wiring harness plate 200. A distance meter 33 is provided on the main body 321 of the clamp 32. The distance meter 33 is activated to measure the vertical distance between the suction cup 322 and the wiring harness plate 200. The second positioning mechanism 30 then compares the actual distance measured with the preset target distance.

[0152] S53 : controlling the suction cup 322 to move toward the direction approaching the wiring harness plate 200 , so that the suction cup 322 contacts the wiring harness plate 200 .

[0153] After comparing the actual distance between the suction cup 322 and the wiring harness plate 200 with the preset target distance, the moving member 31 drives the suction cup 322 to move according to the comparison result, so that the suction cup 322 is attached to the upper surface of the wiring harness plate 200.

[0154] S54 : Control the suction cup 322 to absorb the wiring harness plate 200 .

[0155] Specifically, a vacuum generator 323 is further provided on the main body 321 . The vacuum generator 323 is connected to the suction cup 322 and can control the formation of negative pressure inside the suction cup 322 or change the negative pressure to normal pressure.

[0156] After the suction cup 322 is attached to the upper surface of the wiring harness plate 200 , the vacuum generator 323 is turned on by the controller to form a negative pressure inside the suction cup 322 , so that the suction cup 322 can stably absorb the wiring harness plate 200 .

[0157] S55: Obtain the negative pressure data inside the suction cup 322, and determine whether the suction cup 322 and the wiring harness plate 200 are adsorbed according to the negative pressure data.

[0158] During the process of the suction cup 322 adsorbing the wiring harness plate 200, the vacuum generator 323 can obtain the negative pressure data inside the suction cup 322 and transmit the negative pressure data inside the suction cup 322 to the controller. The controller judges the adsorption state between the suction cup 322 and the wiring harness plate 200 based on the negative pressure data to ensure that the suction cup 322 has stably adsorbed the wiring harness plate 200.

[0159] S56 : If the adsorption is completed, the harness plate 200 is controlled to move to directly above the battery 300 .

[0160] Specifically, the controller controls the moving member 31 to move, thereby driving the suction cup 322 and the wiring harness plate 200 adsorbed thereon to move synchronously to the top of the battery 300 .

[0161] S57 : Controlling the movement of the wiring harness plate 200 according to the deviation value to compensate for the offset between the battery 300 and the wiring harness plate 200 .

[0162] When the moving part 31 drives the wiring harness plate 200 to move, the position of the wiring harness plate 200 is compensated according to the above deviation value. After compensation, the deviation of the current position of the battery 300 can be compensated, thereby making the assembly between the wiring harness plate 200 and the battery 300 more accurate.

[0163] In some embodiments, step S60 specifically includes:

[0164] S61 : The suction cup 322 is controlled to separate from the wiring harness plate 200 , so as to place the wiring harness plate 200 on the battery 300 .

[0165] S62 : Control the suction cup 322 to move away from the harness plate 200 .

[0166] Specifically, when the moving part 31 drives the clamp 32 to move above the battery 300 and the position of the wiring harness plate 200 is determined, the controller controls the vacuum generator 323 to complete the vacuum breaking, so that the internal environment of the suction cup 322 changes from negative pressure to normal pressure. At this time, the adsorption force of the suction cup 322 disappears, and the wiring harness plate 200 is separated from the suction cup 322, thereby placing the wiring harness plate 200 on the battery 300.

[0167] The movable member 31 is controlled to drive the clamp 32 to move in a direction away from the wiring harness plate 200 so that the suction cup 322 is smoothly separated from the wiring harness plate 200 . The movable member 31 can be used to grab the next wiring harness plate 200 .

[0168] In some embodiments, before step S30, the following steps are further included:

[0169] S10: The wiring harness plate 200 on the conveying member 41 is transferred to a position to be lifted and separated from the conveying member 41 .

[0170] S20 : ​​controlling the wiring harness plate 200 at the position to be lifted to be lifted onto the support surface 424 .

[0171] Specifically, the conveying mechanism 40 is disposed on the same side of the second positioning mechanism 30 and the carrier 10 and includes a conveying member 41 and a lifting assembly 42. The conveying member 41 can be used to convey multiple wiring harness panels 200. The second positioning mechanism 30 can grab the wiring harness panels 200 from the conveying mechanism 40, then drive the wiring harness panels 200 to move and place the wiring harness panels 200 on the carrying surface 11 of the carrier 10.

[0172] By providing the conveying mechanism 40 , a plurality of harness plates 200 can be driven to move simultaneously, and at the same time, the harness plates 200 are grasped by the second positioning mechanism 30 , thereby improving assembly efficiency.

[0173] When one of the wiring harness plates 200 on the conveying member 41 moves to the position corresponding to the first positioning mechanism 20, the wiring harness plate 200 is transferred from the conveying member 41 to a position to be lifted and separated from the conveying member 41, so that the wiring harness plate 200 is separated from the conveying member 41. At this time, the conveying member 41 can continue to transport other wiring harness plates.

[0174] The third positioning member 426 protrudes upward and is inserted into the positioning hole of the wiring harness plate 200 to achieve plug-in fit between the tray 425 and the wiring harness plate 200 .

[0175] The driving member 421 pushes the wiring harness plate 200 from the conveyor belt to the inclined surface 423 in the horizontal direction, and pushes the wiring harness plate 200 to continue climbing along the inclined surface 423 to the support surface 424, and finally fixes it on the support surface 424. Then, the second positioning mechanism 30 is controlled to grab the wiring harness plate 200 from the support surface 424 and place it on the carrying surface 11.

[0176] According to one or more embodiments, the wiring harness plate 200 is first conveyed by a conveyor belt, and the driving member 421 is controlled to push the wiring harness plate 200 from the conveyor belt to the inclined surface 423 in the horizontal direction, and push the wiring harness plate 200 to continue climbing along the inclined surface 423 to the support surface 424, and finally fixed on the support surface 424.

[0177] The moving part 31 drives the clamp 32 to move to the top of the wiring harness plate 200 on the support surface 424. The controller turns on the rangefinder 33, measures the distance between the clamp 32 and the wiring harness plate 200, and feeds back to the controller. The controller controls the moving part 31 to drive the clamp 32 to move according to the measurement results, so that the suction cup 322 on the clamp 32 is attached to the upper surface of the wiring harness plate 200.

[0178] The controller activates the vacuum generator 323, creating a negative pressure inside the suction cup 322, allowing the suction cup 322 to absorb the wiring harness plate 200. The moving element 31 raises the suction cup 322 and wiring harness plate 200 to directly above the support surface 11. The vacuum generator 323 is controlled to break the vacuum, causing the negative pressure inside the suction cup 322 to return to normal pressure. The suction cup 322 separates from the wiring harness plate 200, allowing the wiring harness plate 200 to be placed on the support surface 11.

[0179] The first positioning member 21 drives the wiring harness plate 200 to move in the first direction a, and the second positioning member 22 drives the wiring harness plate 200 to move in the second direction b, so as to position the wiring harness plate 200 on the grabbing position 12. At the same time, the moving member 31 drives the clamp 32 to move directly above the battery 300. The visual camera detects the current position of the battery 300, and the controller compares the current position of the battery 300 with the target position and obtains the deviation value between the two.

[0180] The movable member 31 is controlled to move to the position directly above the gripping position 12, and the distance meter 33 is activated again to measure the distance between the clamp 32 and the wiring harness plate 200. The movable member 31 drives the suction cup 322 to move according to the measured distance and to contact the upper surface of the wiring harness plate 200. The vacuum generator 323 is activated to create a negative pressure inside the suction cup 322, which absorbs the wiring harness plate 200.

[0181] The moving part 31 drives the wiring harness plate 200 to move, and during the movement, controls the wiring harness plate 200 to move a corresponding distance based on the deviation value between the current position of the battery 300 and the target position detected by the visual camera, thereby compensating for the position deviation between the wiring harness plate 200 and the battery 300.

[0182] After the final position of the wiring harness plate 200 is determined, the moving part 31 drives the wiring harness plate 200 to move downward close to the battery 300, and then controls the vacuum generator 323 to complete the vacuum breaking, so that the suction cup 322 is separated from the wiring harness plate 200, thereby placing the wiring harness plate 200 on the battery 300, so that the wiring harness plate 200 and the battery 300 can be assembled.

[0183] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0184] The above-described embodiments merely represent several implementation methods of the present application.
