Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle assembly, and particularly to a clamping device for installing a new energy vehicle door. Background Art

[0002] The installation of a new energy vehicle door is a process of precisely matching and fixing the new energy vehicle door assembly (including pre-installed components) with the vehicle body, covering two stages: pre-assembly on the sub-assembly line (component integration) and final assembly on the main assembly line (body matching). It is necessary to ensure that the functionality, sealing performance, and appearance quality of the door meet the vehicle manufacturing standards.

[0003] Due to the differences in the power systems of new energy vehicles, the installation of new energy vehicle doors needs to be coordinated with the assembly sequence of components such as electric motors and suspension systems. For example, the chassis integration is completed first and then the door is installed to ensure structural strength. Therefore, after the new energy vehicle door assembly is welded on the fixture, it usually needs to be transferred to the sub-assembly line for component integration installation, and finally installed on the vehicle.

[0004] After the transfer gantry transfers the new energy vehicle door assembly to the pre-assembly workshop of the sub-assembly line, it is usually necessary to manually carry the new energy vehicle door assembly on the transfer gantry to the corresponding clamping device, and then the operator performs component integration installation on the new energy vehicle door assembly on the clamping device. Since the new energy vehicle door assembly is relatively heavy, manual handling greatly increases the labor intensity of the operator. If a robotic arm is used for handling, for different models of vehicles and doors on different sides of the same model vehicle, the clamping device cannot be adapted simultaneously. Therefore, when installing different models of vehicles or doors on different sides of the same model vehicle, the robotic arm needs to be re-clamped and debugged, and the versatility is poor. Moreover, after the robotic arm clamps and moves the door, it needs to be placed on another clamping device, and then another clamping device needs to be adjusted again to clamp the door, and the process is rather troublesome. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a clamping device for installing a new energy vehicle door, so as to solve the problems in the prior art that when using a robotic arm to carry the new energy vehicle door assembly during the transfer and installation process, for different models of vehicles and doors on different sides of the same model vehicle, the clamping device cannot be adapted simultaneously. Therefore, when installing different models of vehicles or doors on different sides of the same model vehicle, the robotic arm needs to be re-clamped and debugged, and the versatility is poor. Moreover, after the robotic arm clamps and moves the door, it needs to be placed on another clamping device, and then another clamping device needs to be adjusted again to clamp the door, and the process is rather troublesome.

Detailed Embodiment

[0025] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following combines the attached drawings and preferred embodiments to detail the specific implementation manner, structure, characteristics and effects of the present invention as follows.

[0026] Please refer to Figures 1-5 , the present invention provides a technical solution for a clamping device for installing a new energy vehicle door: including a robotic arm 1, a controller, a pushing part 2, an electric suction cup 3 and clamping claws 4 arranged in pairs opposite to each other. The robotic arm 1 is electrically connected to the controller. The pushing part 2 is connected to the robotic arm 1. The clamping claws 4 are connected to the pushing part 2. The pushing part 2 is used to push the two oppositely arranged clamping claws 4 closer to each other. The electric suction cup 3 is connected to the pushing part 2. Both the pushing part 2 and the electric suction cup 3 are electrically connected to the controller;

[0027] The clamping jaw 4 includes a mounting portion 41, a first gear 42, a first double-sided rack 43, and two oppositely arranged clamping plates 44. The first double-sided rack 43 is slidably connected to the mounting portion 41 in the horizontal direction. The clamping surfaces of the two clamping plates 44 are arranged vertically, and the two clamping plates 44 are rotatably connected to the mounting portion 41. The first double-sided rack 43 is disposed between the two clamping plates 44. One end of each of the two clamping plates 44 is connected to a first gear 42, and the first gear 42 meshes with the first double-sided rack 43.

[0028] When using the clamping device for installing a new energy vehicle door of the present invention to clamp a door, first, the controller controls the robotic arm 1 to drive the pushing portion 2 to move the electric suction cup 3 to the corresponding position of the outer door panel of the vehicle. Since the clamping jaw 4 is connected to the pushing portion 2 and the electric suction cup 3 is also connected to the pushing portion 2, the controller controls the electric suction cup 3 to adsorb the outer door panel of the vehicle to position and fix the door, so that the robotic claw can be adjusted to a position where it can clamp the door; after the electric suction cup 3 completes the adsorption of the outer door panel of the vehicle, it sends an electrical signal to the controller, causing the controller to control the pushing portion 2 to push the two pairs of opposite clamping jaws 4 to approach each other. When the two pairs of opposite clamping jaws 4 approach each other, they are approaching the edge of the door at the same time.

[0029] When the edge of the door abuts against the side surface of the first double-sided rack 43 of the clamping jaw 4 facing the door, the first double-sided rack 43 stops moving due to the abutment. Since the first double-sided rack 43 is slidably connected to the mounting portion 41 in the horizontal direction, the two clamping plates 44 are rotatably connected to the mounting portion 41, the first double-sided rack 43 is disposed between the two clamping plates 44, and both of the two clamping plates 44 are connected to a first gear 42, and the first gear 42 meshes with the first double-sided rack 43, relative movement between the first double-sided rack 43 and the first gear 42 will occur, thereby causing the first gear 42 to rotate, driving the two clamping jaws 4 to rotate in the direction of approaching each other. Since the clamping surfaces of the two clamping plates 44 are arranged vertically, when the two clamping jaws 4 approach each other, the clamping surfaces of their clamping plates 44 will abut against the door panel in the direction of the door panel, and clamping of the door can be achieved.

[0030] With this structure, before using the clamping device for installing a new energy vehicle door of the present invention to clamp a door, it is possible to reduce the distinction of the door model and the door direction of the door, increasing the universality of the clamping device to a certain extent. When clamping doors of different models and different directions, the steps of adjusting the clamping program for different models are reduced, simplifying the operation process to a certain extent.

[0031] In this embodiment: The pushing part 2 includes a fixed seat 21, a supporting part 22, a hydraulic rod 23, a second double-sided rack 24, a rotating shaft, and a second gear 26. The fixed seat 21 is connected to the movable end of the robotic arm 1. The fixed end of the hydraulic rod 23 and the upper end of the electric suction cup 3 are both connected to the fixed seat 21. The hydraulic rod 23 is electrically connected to the controller. The movable end of the hydraulic rod 23 is connected to the second double-sided rack 24. There are two supporting parts 22, and the two supporting parts 22 are arranged oppositely. The clamping claws 4 arranged oppositely in pairs are respectively connected to the two supporting parts 22. The two supporting parts 22 are rotatably connected to the fixed seat 21. The upper ends of the two supporting parts 22 are both connected to the second gear 26, and the two second gears 26 are engaged with the second double-sided rack 24.

[0032] The controller controls the movement of the robotic arm 1, thereby controlling the movement and positioning of the electric suction cup 3 to the position where the automotive outer panel is located. When the controller controls the movement of the electric suction cup 3, it also controls the movable end of the hydraulic rod 23 to move downward, thereby pushing the second double-sided rack 24 downward. Since the upper end of the mounting part 41 is connected to the second gear 26, and the second gear 26 is engaged with the second double-sided rack 24, the downward movement of the second double-sided gear drives the second gear 26 to rotate, thereby driving the lower end of the mounting part 41 to rotate away from the door, so that the two oppositely arranged clamping claws 4 can move away from each other, facilitating the placement of the door between the two clamping claws 4. After the electric suction cup 3 adsorbs and positions the automotive outer panel, the controller will control the movable end of the hydraulic rod 23 to move upward, thereby driving the second gear 26 to rotate, and then driving the lower end of the supporting part 22 to rotate towards the door direction, so that the two clamping claws 4 move closer to each other. With this structure, the pushing part 2 can push the two clamping claws 4 to move closer to each other.

[0033] In this embodiment: The supporting part 22 includes a rotating rod 221, a first sliding rod 222, a slider 226, and a second sliding rod 224. The upper end of the rotating rod 221 is connected to the second gear 26. The first sliding rod 222 is arranged vertically. The clamping claw 4 is connected to the first sliding rod 222. The side surface of the first sliding rod 222 facing the door is recessed inward to form a first sliding groove 223. The first sliding groove 223 is arranged vertically. The slider 226 is slidably connected to the first sliding groove 223. The lower end of the rotating rod 221 is hinged to the slider 226. The second sliding rod 224 is arranged horizontally. The upper end of the first sliding rod 222 is slidably connected to the second sliding rod 224.

[0034] The rotation of the second gear 26 drives the rotation of the rotating rod 221, thereby driving the lower end of the rotating rod 221 to perform a circular motion, thereby driving the slider 226 to move up and down along the first chute 223. Since the second slide bar 224 is horizontally arranged and the upper end of the first slide bar 222 is slidably connected to the second slide bar 224, when the lower end of the rotating rod 221 performs a circular motion, the second slide bar 224 shares the lateral movement of the connecting rod 11, so that the first slide bar 222 can always remain vertical during movement. Since the clamping jaw 4 is connected to the first slide bar 222, the clamping direction of the clamping jaw 4 always remains unchanged at this time, thereby reducing the situation that the clamping angle of the clamping jaw 4 changes continuously due to the rotation of the lower end of the support part 22 with the gear, resulting in unstable clamping of the clamping jaw 4.

[0035] In this embodiment: The support part 22 further includes an electric telescopic rod 227 and a first pressure sensor 228. The fixed end of the electric telescopic rod 227 is connected to the first slide bar 222, the movable end of the electric telescopic rod 227 is connected to the clamping jaw 4, the first pressure sensor 228 is connected to the side surface of the first double-sided rack 43 facing the car door, and the first pressure sensor 228 and the electric telescopic rod 227 are electrically connected to the controller.

[0036] When the connecting rod 11 rotates to drive the first slide bar 222 to move, the first slide bar 222 will drive the clamping jaw 4 to move. When the clamping jaw 4 moves and the side surface of the first double-sided rack 43 facing the car door abuts against the edge of the car door, the pressure generated by the edge of the car door on the first pressure sensor 228 is converted into an electrical signal by the pressure sensor and sent to the controller as an electrical signal. After receiving the electrical signal, the controller controls the second double-sided rack 24 to stop moving, so that the first slide bar 222 stops moving. At this time, the controller controls the electric telescopic rod 227 connected to the mechanical claw that is not abutted to extend until the first double-sided rack 43 of this mechanical claw abuts against the car door, and the first pressure sensor 228 sends an electrical signal to the controller due to the pressure, causing the controller to control the corresponding electric telescopic rod 227 to stop extending. With this structure, the clamping jaw 4 can clamp in accordance with the shape of the edge of the car door, and a clamping device for installing a new energy vehicle door of the present invention can be applicable to car doors of various models.

[0037] In this embodiment: A convex block 45 protrudes outward from the side surface of the first double-sided rack 43 facing the car door. A positioning hole is recessed downward on the upper end surface of the convex block 45, and a second pressure sensor 452 is connected to the upper end surface of the convex block 45; It further includes a sliding part 27. The sliding part 27 is slidably connected to the first slide bar 222 along the first slide bar 222. The fixed end of the electric telescopic rod 227 is fixedly connected to the sliding part 27, and both the second pressure sensor 452 and the sliding part 27 are electrically connected to the controller.

[0038] When the electric telescopic rod 227 drives the clamping jaw 4 to abut against the edge of the car door, the first pressure sensor 228 connected to the first double-sided rack 43 is pressed to send an electrical signal to the controller, causing the controller to control the electric telescopic rod 227 to stop extending and also send an electrical signal to the sliding part 27, causing the sliding part 27 to drive the clamping jaw 4 to move upward, so that the position of the positioning hole can be moved to the position where the hinge shaft is located, so that the hinge shaft can fall into the positioning hole, enabling the clamping jaw 4 to clamp the hinge shaft and further ensuring the stability of clamping.

[0039] When the hinge shaft successfully passes through the positioning hole, the pressure on the upper end surface of the hinge against the convex block 45 causes the second pressure sensor 452 to send a signal to the controller, causing the controller to control the sliding part 27 to stop sliding. At the same time, the controller controls the electric telescopic rod 227 to continue extending, so that the clamping jaw 4 moves further towards the car door. The first double-sided rack 43 stops moving due to the abutment of the car door, so that the two opposite clamping plates 44 clamp the car door.

[0040] In this embodiment: A single-sided rack 28 is connected to the inner side wall of the first sliding groove 223, and the single-sided tooth part faces the car door direction. The sliding part 27 includes a sliding block 271, a third gear 272 and a motor 273. The fixed end of the electric telescopic rod 227 is fixedly connected to the sliding block 271. The sliding block 271 is slidably connected to the first sliding rod 222 up and down. The motor 273 is connected to the sliding block 271. The third gear 272 is connected to the output end of the motor 273. The third gear 272 meshes with the single-sided rack 28, and the motor 273 is electrically connected to the controller.

[0041] The controller receives the electrical signal to control the rotation of the motor 273, thereby controlling the rotation of the third gear 272, and then driving the sliding block 271 to slide up and down along the first sliding rod 222. With this structure, the sliding part 27 can slide up and down along the first sliding rod 222.

[0042] In this embodiment: The upper edge of the positioning hole inclines downward to form an inclined surface. Springs 453 and moving parts 454 are connected to both ends of the convex block 45. A sliding groove 455 is recessed inside the moving part 454. The convex block 45 can slide along the sliding groove 455. The upper end surface of the sliding part 27 inclines along the inclined direction of the convex block 45. The spring 453 is located inside the sliding groove 455, and both ends of the spring 453 are respectively connected to the inner wall of the sliding groove 455 and the side wall of the convex block 45.

[0043] When the hinge shaft reaches the upper surface of the bump 45 and the clamping jaw 4 drives the bump 45 to continue moving upward, the lower end of the hinge shaft moves along the inclined surface, making it easier for the hinge shaft to fall into the positioning hole. Also, since the bump 45 can slide along the sliding groove 455, when the two clamping plates 44 move closer to each other, the bump 45 will not resist the clamping of the clamping plate 44, reducing the possibility of the bump 45 affecting the clamping jaw 4.

[0044] In this embodiment: A groove 211 is formed by downward depression on the upper end face of the pushing part 2, and an internal thread 212 is formed on the inner side wall of the groove 211. The robotic arm 1 is rotatably connected with a connecting rod 11, and an external thread 213 is formed on the outer side wall of the connecting rod 11. The external thread 213 is screwed with the internal thread 212; A first communication interface is provided on the bottom wall of the groove 211, and a second communication interface is provided on the lower end face of the connecting rod 11. The connection of the first communication interface and the second communication interface enables the controller to control the pushing part 2, the electric suction cup 3, and the clamping jaw 4.

[0045] A bracket is provided on the sub-packaging line. After the controller controls the robotic arm 1 to complete the clamping of the car door, the robotic arm 1 drives the car door to move to the position of the bracket, so that the bracket supports the second sliding rod 224. Then the controller controls the connecting rod 11 to rotate, making the external thread 213 and the internal thread 212 disengage from each other, so that the pushing part 2, the electric suction cup 3, and the clamping jaw 4 are disengaged from the control of the controller. Then the operator can install components on the car door on the bracket; After the robotic arm 1 is separated from the pushing part 2, it can move to the pushing part 2 of another clamping device under the control of the controller to screw the internal thread 212 and the external thread 213 for installation, so that the first communication interface and the second communication interface are connected, enabling the controller to control the pushing part 2, the electric suction cup 3, and the clamping jaw 4 again.

[0046] With this structure, when using the clamping device for installing a new energy vehicle door of the present invention to install a new energy vehicle door, after the robotic arm 1 clamps and moves the car door, there is no need to place the car door on another clamping device again, and there is no need to adjust another clamping device to clamp the car door again, which is more convenient for clamping, transporting, and integrally installing components on the car door.

[0047] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications into equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention.
