[0037] In the automobile general assembly workshop, the lifting device is a very common tooling equipment, which is used to lift the automobile body during the automobile assembly process. The shape and structure of the lifting device depend on the structure of the automobile body. Since the structures of automobiles of each model are different, the shape and structure of the lifting device required for each automobile model are also different. These lifting devices have one thing in common - the degree of flexibility is not high. Each lifting device is only applicable to one model. In order to meet the assembly requirements of different models, the automobile general assembly workshop usually sets up separate lifting devices for each model. Enterprises generally build different production lines to adapt to models of different platforms, which obviously requires a large amount of additional investment costs; in addition, after the number of production lines increases, the operating rate of each production line will decrease, the on-site management difficulty is large, and the workload of workers is not saturated, which undoubtedly increases the manufacturing cost for the enterprise. Therefore, the low versatility of the lifting device is an urgent problem to be solved by technical personnel in this field at present.

[0038] The present utility model proposes a lifting device system.

[0039] Please refer to Figure 1 , in an embodiment of the present utility model, the lifting device system 100 includes: a lifting frame 1, a tray assembly 2, a plurality of positioning members 3, and a robot assembly 4; the lifting frame 1 has a supporting portion 11 and a positioning portion 12, the supporting portion 11 and the positioning portion 12 are arranged at intervals in the front-rear direction, and the supporting portion 11 is used to support the vehicle body; the tray assembly 2 is fixedly arranged on the lifting frame 1 and is provided with a plurality of placement areas; for the plurality of positioning members 3, one of the positioning members 3 is installed on the positioning portion 12, and the remaining positioning members 3 are respectively placed in the plurality of placement areas, and the plurality of positioning members 3 are respectively used to position the plurality of vehicle bodies; the robot assembly 4 is arranged on one side of the lifting frame 1 and is used to transfer the positioning member 3 between the positioning portion 12 and the placement area.

[0040] The hanger 1 of the technical solution of the utility model includes two parts, a supporting part 11 and a positioning part 12. Both the supporting part 11 and the positioning part 12 are in contact with the vehicle body. Generally, the supporting part 11 is designed with a larger contact surface to support most of the weight of the vehicle body. The positioning part 12 is also in contact with the vehicle body and also plays a role in supporting the weight of the vehicle head. Generally, two supporting parts 11 are arranged at the rear of the hanger 1, and the two supporting parts 11 are spaced apart in the left-right direction. Generally, two positioning parts 12 are arranged at the front of the hanger 1, and the two positioning parts 12 are spaced apart in the left-right direction. The two positioning parts 12 and the two supporting parts 11 form a plane for placing the vehicle body at four points. During the transportation process, the hanger 1 also needs to pass through multiple workstations for vehicle body processing. In order to facilitate processing, it is necessary to position the vehicle body. Therefore, the positioning part 12 has another function, that is, it is used to install the positioning member 3, and the positioning member 3 positions the vehicle body to prevent the vehicle body from moving in the front-rear direction or the left-right direction. However, for different vehicle bodies, the structures of the vehicle bodies are different, and the positions where the positioning member 3 cooperates with the vehicle body are also different. In order to improve the versatility of the lifting tool, one solution is to set only one type of positioning member 3 and change the installation position of the positioning member 3; another solution is to ensure that the installation position remains unchanged and multiple types of positioning members 3 are set. Since the solution of changing the installation position requires adjustment in both the front-rear direction and the left-right direction, on the one hand, a complex transmission component needs to be set, and on the other hand, the transmission component also needs to bear a certain vehicle body weight, and the stiffness requirement for the transmission component is relatively high. Therefore, the utility model adopts the solution of setting multiple types of positioning members 3. In order to facilitate the taking and placing of the positioning member 3, the tray assembly 2 is fixedly arranged on the hanger 1, near the positioning member 3. The tray assembly 2 is provided with multiple placement areas for placing multiple different positioning members 3. The robot assembly 4 is arranged on one side of the hanger 1. The robot group is used to place different positioning members 3 on the positioning part 12, or take out the positioning members 3 located on the positioning part 12 and place them in the corresponding placement areas to realize the switching of the positioning members 3.

[0041] To achieve the installation and placement of the positioning member 3, the tray assembly 2 includes a plurality of positioning seats 21 and a tray 22. The positioning seats 21 are fixedly installed on the tray 22. The positioning seats 21 have mounting holes 211 penetrating in the up and down direction; the positioning member 3 extends in the up and down direction, and are sequentially provided with: a positioning shaft 31, a positioning plate 32 and a first positioning pin 33 in the up and down direction; the positioning shaft 31 is used to be installed in the mounting hole 211 to place the positioning member 3 in the positioning seat 21, the positioning plate 32 is used to abut against the positioning seat in the up and down direction, and the first positioning pin 33 is used to cooperate with and position the vehicle body; for different positioning members 3, the installation positions of the positioning shafts 31 are the same, but for different positioning members 3, at least in one of the left and right directions and the front and back directions, the distance between the positioning shaft 31 and the positioning pin is different. In order to meet the requirement of being able to position multiple vehicle bodies, therefore, at least in one of the front and back directions or the left and right directions, the distance between the positioning shafts 31 of the multiple positioning members 3 and the first positioning pin 33 gradually increases to correspond to different vehicle bodies. It is worth mentioning that positioning seats 21 are also provided on the positioning portion 12 for placing the positioning members 3.

[0042] Due to the cooperation between the mounting hole 211 of the positioning seat 21 and the positioning shaft 31 of the positioning member 3, the positioning member 3 cannot be circumferentially positioned, resulting in the first positioning pin 33 being able to rotate around the axis of the positioning shaft 31. Therefore, the position of the first positioning pin 33 is not fixed. So, it cannot cooperate well with the vehicle body. Therefore, in an embodiment, a groove 212 extending in the left and right direction is provided on the side of the positioning seat 21 for abutting against the positioning plate 32, and a convex block 34 extending in the left and right direction is provided on the side of the positioning plate for abutting against the positioning seat 21. The convex block 34 is used to cooperate with the groove 212 to limit the positioning member 3 circumferentially, thereby restricting the rotation of the positioning member 3 and fixing the position of the first positioning pin 33 to ensure precise cooperation with the vehicle body.

[0043] To enable the robot assembly 4 to clamp the positioning member 3, specifically, the robot assembly 4 includes: a robotic arm 41, a slide cylinder 42, and; generally, the robotic arm 41 is set as a six-axis robotic arm 41 to ensure sufficient degrees of freedom. The robotic arm 41 is arranged on one side of the hanger 1 in the left and right direction;

[0044] The sliding table cylinder 42 is installed at the end of the robotic arm 41 for supply connection. The sliding table cylinder 42 has first movable ends movably arranged in the front-rear direction at both ends in the front-rear direction; two clamping jaws 43 are respectively fixedly connected to the two first movable ends; the two clamping jaws 43 can approach or move away from each other; for the convenience of the clamping jaws 43 to pick up, the positioning plate 32 includes a positioning plate main body 321 and a convex portion 322. The positioning plate main body 321 protrudes upward and extends along both sides in the left-right direction to form the convex portion 322. The convex portion 322 and the positioning plate main body 321 form concave portions on both sides of the convex portion 322 in the left-right direction. The concave portions are used for the clamping jaws 43 to be clamped and picked up.

[0045] Since the clamping jaws 43 need to move in the left-right direction of the convex portion 322, the first positioning pin 33 cannot be collinear with the convex portion 322 in the left-right direction to avoid interference between the first positioning pin 33 and the movement track of the clamping jaws 43. Therefore, the convex portion 322 and the first positioning pin 33 are arranged with a dislocation in the left-right direction.

[0046] In order to enable the robot component 4 to quickly and accurately identify the position of the positioning member 3 and then perform grasping, the robot component 4 further includes a camera 44 and a light source. The camera 44 and the light source are fixedly installed on the robotic arm 41. A reference hole 221 is provided on the tray 22 for the camera 44 to identify, divide the placement area, pick up the corresponding positioning member 3, and ensure the accurate use of the positioning member 3.

[0047] Because one positioning pin cooperates with the vehicle body and cannot provide good limiting for the vehicle body, and the vehicle body can still rotate around one positioning pin, two positioning members 3 need to be provided for each type. Correspondingly, both the tray assembly 2 and the robot component 4 are provided with two groups. The two groups of tray assemblies 2 are arranged at intervals in the left-right direction, and the two groups of robot components 4 are respectively arranged on both sides of the hanger 1 in the left-right direction.

[0048] In the lifting tool system 100, the lifting tool system 100 further includes a slide rail. The hanger 1 is slidably installed on the slide rail and can be moved along the slide rail to each working station for the next processing step.

[0049] Since the position of the hanger 1 on the slide rail is not fixed, when replacing the positioning member 3, it is necessary to limit the hanger 1 to prevent the hanger 1 from moving along the track and affecting the assembly of the positioning member 3. In one embodiment, the hanger 1 is provided with a positioning hole with a downward opening; the lifting tool system 100 further includes a limiting component 5. The limiting component 5 includes: a cylinder 51 and a second positioning pin. The cylinder 51 is arranged in the up-down direction and has a second movable end movably arranged in the up-down direction; the second positioning pin is fixedly installed on the second movable end in the up-down direction for cooperation with the positioning hole.

[0050] The present utility model also provides an automobile processing line body, which includes a spreader system 100. The specific structure of the spreader system 100 refers to the above embodiments. Since this automobile processing line body adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the automobile processing line body includes a spreader system 100, and the spreader system 100 includes: a hanger 1, a tray assembly 2, a variety of positioning members 3, and a robot assembly 4; the hanger 1 has a supporting portion 11 and a positioning portion 12, the supporting portion 11 and the positioning portion 12 are spaced apart in the front-rear direction, and the supporting portion 11 is used to support the vehicle body; the tray assembly 2 is fixedly arranged on the hanger 1 and is provided with a plurality of placement areas; for the variety of positioning members 3, one of the positioning members 3 is installed on the positioning portion 12, and the remaining positioning members 3 are respectively placed in a plurality of the placement areas, and the variety of positioning members 3 are respectively used to position the variety of vehicle bodies; the robot assembly 4 is arranged on one side of the hanger 1 and is used to transfer the positioning members 3 between the positioning portion 12 and the placement areas.
