[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1 Please see Figures 1-7 This invention provides a tricycle assembly robot, including a support base 1, a lifting seat 2 movably mounted on the support base 1, and a first drive mechanism 4 driving the lifting seat 2 to move up and down; a movable seat 3 movably mounted on the lifting seat 2, and a second drive mechanism 5 driving the movable seat 3 to move up and down; a carrier seat 9 is fixedly connected to the lifting seat 2, the carrier seat 9 being used to support the floor of the electric tricycle (hereinafter referred to as the floor); the floor is used to be placed at an angle on the carrier seat 9, specifically, the carrier seat 9 is provided with a placement groove 91, one end of the floor for assembling the taillight is used to fit inside the placement groove 91, the placement groove 91 has two mutually perpendicular inner walls, and the opening of the placement groove 91 faces upward; in addition, a baffle 92 is provided inside the placement groove 91.

[0029] The robotic arm also includes a clamping mechanism 8 and a connecting component 6. The connecting component 6 is fixedly mounted on the movable seat 3. There are two clamping mechanisms 8, both of which are used to clamp the base plate. When clamping the base plate, the two clamping mechanisms 8 respectively contact the two foot pedals 10 on the base plate. A sling 7 is provided between each clamping mechanism 8 and the connecting component 6.

[0030] When the base plate is placed in the placement slot 91, the base plate is tilted and abuts against the base plate by the baffle 92; at the same time, one end of the base plate is clamped by two clamping mechanisms 8 and the moving seat 3 is driven to move by the second drive mechanism 5 so that the two slings 7 are straightened and the two slings 7 are symmetrically arranged.

[0031] The support base 1 is provided with a pressing mechanism 11, which is used to press against the bottom plate, and the pressing mechanism 11 is inclined on the support base 1.

[0032] The pressing mechanism 11 includes two mounting seats 111 fixedly mounted on the support seat 1, and the two mounting seats 111 are symmetrically arranged. Each mounting seat 111 is fixedly mounted with a first hydraulic cylinder 112. The first hydraulic cylinder 112 is inclined. The two first hydraulic cylinders 112 are symmetrically arranged, and the piston rod of each first hydraulic cylinder 112 is fixedly connected to an abutting pulley 113. The abutting pulley 113 is used to abut against the outer wall of the same side of the base plate. Of course, in the initial state, the piston rod of the first hydraulic cylinder 112 is not extended, that is, the abutting pulley 113 is not abutting against the base plate.

[0033] The base plate is placed at an angle on the support 9, and two clamping mechanisms 8 are used to clamp the end of the base plate away from the placement groove 91. Since the two clamping mechanisms 8 are connected by two slings 7, the end of the base plate away from the placement groove 91 is lifted; simultaneously, the base plate is abutted by two abutting pulleys 113. Figure 1 As shown, this allows the base plate to be stably placed on the support seat 9.

[0034] The connecting assembly 6 includes a fixed column 61 that is fixedly connected to the movable seat 3, and a fixed strip 62 is fixedly connected to the fixed column 61. Two movable shafts 63 are movably arranged on the fixed strip 62, and both movable shafts 63 are movably connected to the fixed strip 62 through bearings. The two movable shafts 63 are symmetrically arranged on both sides of the axis of the fixed column 61. A connecting sleeve 64 is fixedly sleeved on the outside of each movable shaft 63. The two connecting sleeves 64 are symmetrically arranged on both sides of the axis of the fixed column 61. One end of the sling 7 is fixedly mounted on the connecting sleeve 64, and the other end of the sling 7 is fixedly connected to the clamping mechanism 8.

[0035] The clamping mechanism 8 includes a clamping seat 81, on which a right-angle clamping plate 84 is fixedly mounted. The right-angle clamping plate 84 is used to cooperate with the base plate. A second hydraulic cylinder 82 is installed on the clamping seat 81. The second hydraulic cylinder 82 is a thin-type cylinder. The piston rod of the second hydraulic cylinder 82 is fixedly connected to a clamping piece 85. The clamping piece 85 is used to clamp the upward side of the base plate after assembly. One inner wall of the right-angle clamping plate 84 is used to contact the downward side of the base plate after assembly. By extending the piston rod of the second hydraulic cylinder 82, the base plate is clamped between the clamping piece 85 and the right-angle clamping plate 84.

[0036] A connector 86 is fixedly installed on the clamping seat 81, and the end of the sling 7 away from the connecting sleeve 64 is fixedly installed on the connector 86; at the same time, in order to facilitate holding the entire clamping mechanism 8, a hand-held seat 83 is provided on the clamping seat 81, and by holding the hand-held seat 83, the clamping mechanism 8 can be easily matched with the base plate.

[0037] In this embodiment, the support base 1 can be fixed at a suitable position. An external robot places the end of the base plate near the taillight into the placement slot 91, while one side of the base plate abuts against the stop strip 92. Simultaneously, the second drive mechanism 5 drives the movable seat 3 to descend to a suitable position to facilitate the clamping mechanism 8 clamping the base plate. That is, the sling 7 is not taut when the hand-held clamping mechanism 8 clamps the base plate. Specifically, the right-angle clamping plate 84 is engaged with the end of the base plate away from the placement slot 91 by the hand-held gripper 83, causing the right-angle clamping plate 84 to abut against the foot pedal 10 on the base plate. This is achieved by extending the piston rod of the second hydraulic cylinder 82. The clamping plate 85 clamps the base plate, and the end of the base plate away from the placement slot 91 is clamped between the right-angle clamping plate 84 and the clamping plate 85. The two right-angle clamping plates 84 respectively contact the two foot pedals 10 on the base plate. After the two clamping mechanisms 8 have finished clamping, the second drive mechanism 5 drives the moving seat 3 to move upward, causing the two slings 7 to straighten. The base plate remains inside the placement slot 91, and the piston rod of the first hydraulic cylinder 112 extends, causing the abutment pulley 113 to contact the base plate. At this time, the external robot equipment can be released and detached from the base plate, and the base plate is stably placed on the support seat 9. Figure 1 As shown.

[0038] Next, the electric tricycle frame to be fitted is moved using a moving or transferring mechanism to align the base plate with the frame at the hinge position. Then, bolts and nuts are installed to achieve the hinge connection between the base plate and the electric tricycle frame. Because the base plate is tilted, it facilitates both the hinge connection between the base plate and the electric tricycle frame and the engagement of the hydraulic support rod (used to drive the base plate to rotate). Compared to the traditional method of manually placing the base plate flat on the electric tricycle frame and installing bolts underneath to hinge the base plate, followed by flipping the base plate after hinge, the assembly operation is more convenient, thus improving assembly efficiency.

[0039] Then, the first drive mechanism 4 drives the lifting seat 2 to descend, further driving the support seat 9 and the movable seat 3 to descend. During the descent of the support seat 9 and the movable seat 3, since the bottom plate is hinged to the electric tricycle frame, it is easy for the bottom plate to deflect under the action of gravity. Due to the installation of the sling 7, one end of the bottom plate is always suspended. The placement slot 91 is located at a suitable position below the bottom plate, so that the bottom plate is completely separated from the placement slot 91. At this time, the descent of the lifting seat 2 can be stopped. Next, the second drive mechanism 5 drives the movable seat 3 to descend slowly. Under the action of gravity, the bottom plate continues to deflect. One end of the bottom plate is clamped by the clamping mechanism 8 and gradually approaches the electric tricycle frame until the bottom plate is in a horizontal state. This allows the base plate to be placed flat on the electric tricycle frame, avoiding the traditional manual flipping method and preventing potential hazards such as the base plate flipping rapidly due to human error and impacting the electric tricycle frame or assembly personnel. Of course, if jamming occurs (i.e., the base plate does not flip) during the descent of the lifting seat 2 driven by the first drive mechanism 4 or the moving seat 3 driven by the second drive mechanism 5, the base plate can be pressed down by the abutting pulley 113 driven by the first hydraulic cylinder 112, which can assist in the flipping of the base plate and thus prevent the base plate from jamming and not flipping. In this embodiment, the pressing mechanism 11 not only ensures the stable placement of the base plate but also prevents the base plate from jamming and not flipping.

[0040] After the base plate is placed flat on the electric tricycle frame, the piston rod of the second hydraulic cylinder 82 is reset, and the clamping mechanism 8 loosens its grip on the base plate, allowing the two clamping mechanisms 8 to be removed. At this point, the electric tricycle and the base plate can be transferred by an external robot. After the base plate and other components are transferred, the first drive mechanism 4 and the second drive mechanism 5 respectively drive the lifting seat 2 and the moving seat 3 to reset, allowing the next assembly work to proceed.

[0041] Example 2 Please see Figure 1 , Figure 2 and Figure 8 Based on Embodiment 1, the first driving mechanism 4 includes a drive motor 41 mounted on the top of the support base 1. The first drive motor 41 also includes a lead screw 42, which is rotatably mounted on the support base 1 via a bearing. The output shaft of the drive motor 41 is fixedly connected to the top of the lead screw 42. The lead screw 42 passes through the lifting base 2 and is threadedly connected to the lifting base 2, that is, the lifting base 2 is provided with a threaded hole that matches the lead screw 42.

[0042] Meanwhile, two first linear guide rails 12 are provided on the support base 1, and both first linear guide rails 12 are vertically arranged; each first linear guide rail 12 is equipped with a first slider 121, and all first sliders 121 are fixedly connected to the lifting base 2, thereby enabling the lifting base 2 to move up and down; by driving the lead screw 42 to rotate through the drive motor 41, the lifting base 2 can be moved up and down.

[0043] Example 3 Please see Figures 1-3 Based on Embodiment 2, the second drive mechanism 5 includes a lifting motor 51 installed on the top of the lifting seat 2, a lifting rope 52 wound around the lifting motor 51, and the bottom end of the lifting rope 52 is fixedly connected to the moving seat 3; the second drive mechanism 5 also includes a guide pulley 53, which is fixedly installed on the moving seat 3, and the lifting rope 52 passes around the guide pulley 53.

[0044] Meanwhile, two second linear guide rails 21 are provided on the lifting seat 2, and the two second linear guide rails 21 are set vertically; each second linear guide rail 21 is equipped with a second slider 211, and the second slider 211 is fixedly connected to the moving seat 3; by driving the lifting rope 52 to move through the lifting motor 51, the moving seat 3 can be moved up and down in cooperation with the second slider 211 and the second linear guide rail 21.

[0045] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
