[0039] With the gradual upgrading and transformation of modern factories, the research and application of intelligent manufacturing equipment and automated production lines are the key to the upgrading of modern factories. These equipment realize automatic control and optimized scheduling of the production process by integrating sensors, actuators, controllers and other elements. For example, using intelligent robots for precision machining, automated assembly, automated handling and other operations greatly improves production efficiency and product quality.

[0040] The handling gripper is an indispensable part of the automated production line. In the automobile factory, the handling gripper is usually used to move the vehicle body. However, in the related art, the handling gripper can only handle and grasp a specific vehicle model corresponding thereto. The existing vehicle body side wall handling gripper is mostly single-vehicle type special, and a set of side wall handling gripper and its supporting switching trolley need to be developed for each new vehicle type, resulting in different handling grippers for different vehicles, high development cost, 8-10 sets of handling grippers + switching trolleys for left and right side wall production lines, long switching time, and about 4 minutes for one person to switch a set of special gripper when switching production models, 40 minutes for 10 sets of grippers, and a large storage space of about 45 square meters is occupied for each set of special gripper, which not only occupies a large amount of space in the factory, but also requires switching the corresponding handling gripper when switching production models, resulting in reduced production efficiency and increased production cost.

[0041] In view of this, in order to improve the production efficiency of the factory and reduce the production cost, while reducing the space occupied by the handling gripper in the factory, the present application provides a handling gripper, which comprises a frame, a positioning pin and a clamping block.

[0042] A locating pin is provided on the frame, and the locating pin is used to engage with the locating hole on the vehicle body. A clamping block is provided on the frame, and the clamping block is suitable for clamping the side of the vehicle body. The position of the clamping block on the frame is adjustable to adapt to a variety of different vehicle bodies.

[0043] In the above solution, a clamping block is mounted on the frame and is suitable for clamping the vehicle body side. This allows the vehicle body side to be clamped to the handling gripper via the clamping block, allowing the vehicle body to be transported via the handling gripper. The clamping block's position on the frame is adjustable to accommodate a variety of vehicle bodies. This allows a single side gripper to clamp a variety of vehicle body side panels, increasing the gripper's adaptability, improving production efficiency, reducing production costs, and reducing the space occupied by the gripper within the factory.

[0044] For the convenience of description, the following embodiments are described by taking a transport gripper according to an embodiment of the present application as an example.

[0045] Please refer to Figures 1 to 3 , Figure 1 A schematic structural diagram of a transport gripper 100 provided in one embodiment of the present application; Figure 2 for Figure 1 Front view of Figure 3 for Figure 1 side view.

[0046] In this embodiment, the carrying grabber 100 includes a frame 110, a positioning pin 120 and a clamping block 130. The positioning pin 120 is set on the frame 110, and the positioning pin 120 is used to plug and cooperate with the positioning hole on the vehicle body. The clamping block 130 is set on the frame 110, and the clamping block 130 is suitable for clamping the side of the vehicle body. The position of the clamping block 130 on the frame 110 is adjustable to adapt to a variety of different vehicle bodies.

[0047] The positioning pin 120 is provided on the frame 110 and is provided on one side of the frame 110 along the thickness direction of the frame 110. During the use of the carrying gripper 100, the positioning pin 120 can be inserted into the positioning hole on the vehicle body, thereby realizing the positioning function of the carrying gripper 100 on the vehicle body, so that the position of the carrying gripper 100 and the vehicle body is relatively fixed. For example, the positioning hole can be provided on the side of the vehicle body, and the positioning pin 120 provided on the frame 110 is plugged into the positioning hole provided on the side of the vehicle body, and the positioning pin 120 is inserted into the positioning hole to realize the positioning of the carrying gripper 100 on the side of the vehicle body. The clamping block 130 is provided on the frame 110 and is provided on one side of the frame 110 along the thickness direction of the frame 110. The clamping block 130 is suitable for clamping the side of the vehicle body. The carrying gripper 100 can grasp the side of the vehicle body through the clamping block 130, so that the carrying gripper 100 can drive the side of the vehicle body to move.

[0048] Further, the position of the clamping block 130 on the frame 110 is adjustable to adapt to different vehicle bodies, that is, the clamping block 130 is arranged on the frame 110, and the position of the clamping block 130 and the frame 110 can be relatively moved. Since the carrying gripper 100 is usually used to clamp the side walls of different vehicle bodies through the clamping block 130, the length of the vehicle body or the height of the vehicle body can be different for different vehicle models, and the clamping block 130 of the carrying gripper 100 is arranged to be adjustable, so that the carrying gripper 100 can adapt to different vehicle models.

[0049] Specifically, the clamping block 130 is arranged on the frame 110, and the clamping block 130 is suitable for clamping the side walls of the vehicle body. The position of the clamping block 130 on the frame 110 is adjustable to adapt to different vehicle bodies, so that the same carrying gripper 100 can adapt to different vehicle models, expand the application range of the carrying gripper 100, reduce the occupied space of the carrying gripper 100 in the factory building, improve the space utilization of the factory building, improve the production efficiency, and reduce the production cost.

[0050] In some embodiments, the moving assembly 150 is arranged on the frame 110, and the clamping block 130 is arranged on the moving assembly 150. The moving assembly 150 includes a movable rail 151, a fixed rail 152, and a driving motor 153. The clamping block 130 is directly connected with the movable rail 151, and the clamping block 130 is arranged on the movable rail 151. The driving motor 153 is connected with the movable rail 151, and the driving motor 153 drives the movable rail 151 to move, so as to drive the clamping block 130 to move together, thereby expanding the application range of the carrying gripper 100.

[0051] Please refer to Figures 1 to 3 In this embodiment, the clamping block 130 includes a first clamping block 131 and a second clamping block 132. In the first direction, the first clamping block 131 and the second clamping block 132 are arranged on the frame 110 in a spaced manner. In the first direction, the position of at least one of the first clamping block 131 and the second clamping block 132 on the frame 110 is adjustable.

[0052] In the first direction, the first clamping block 131 and the second clamping block 132 are arranged at intervals on the frame 110, that is, the first clamping block 131 and the second clamping block 132 are spaced apart on the frame 110. Since the first clamping block 131 and the second clamping block 132 clamp the vehicle body during operation of the carrying gripper 100, the first clamping block 131 and the second clamping block 132 are arranged at intervals, which can clamp different parts of the vehicle body, effectively disperse the clamping force of the carrying gripper 100 on the vehicle body, thereby reducing the risk of stress concentration of the carrying gripper 100 when carrying the vehicle body, and improving product quality. Moreover, in the first direction, the first clamping block 131 and the second clamping block 132 are arranged at intervals on the frame 110, which can also provide support points at multiple positions of the side wall of the vehicle body. This multi-point support mode significantly enhances the stability of the gripper during the carrying process, and reduces the risk of side wall shaking or falling off.

[0053] In actual production, the shape and size of the side wall of the vehicle body are various and complex. The first clamping block 131 and the second clamping block 132 arranged at intervals can better adapt to these different shapes and ensure that the gripper can firmly hold the side wall. The first clamping block 131 and the second clamping block 132 arranged at intervals enable the carrying gripper 100 to quickly find and lock the appropriate clamping position when approaching the side wall of the vehicle body, thereby shortening the preparation time before carrying.

[0054] The position of at least one of the first clamping block 131 and the second clamping block 132 on the frame 110 is adjustable, so that the carrying gripper 100 can adapt to vehicle bodies of different sizes and shapes, improve the flexibility and efficiency of carrying, expand the application range of the carrying gripper 100, so that it is not necessary to set up a carrying gripper 100 for each vehicle model, reduce the space occupied by the carrying gripper 100 in the factory building, improve the space utilization of the factory building, improve the production efficiency, and reduce the production cost.

[0055] Please refer to Figures 1 to 3 In the present embodiment, the clamping block 130 further comprises a third clamping block 133 and a fourth clamping block 134. In the second direction, the third clamping block 133 and the fourth clamping block 134 are arranged at intervals on the frame 110. In the second direction, the position of at least one of the third clamping block 133 and the fourth clamping block 134 on the frame 110 is adjustable. The second direction is perpendicular to the first direction.

[0056] In the second direction, the third clamping block 133 and the fourth clamping block 134 are arranged at intervals on the frame 110, that is, in the second direction, the third clamping block 133 and the fourth clamping block 134 are spaced apart on the frame 110 by a distance. Since the carrying gripper 100 clamps the vehicle body during operation, the third clamping block 133 and the fourth clamping block 134 are arranged at intervals, which can clamp different parts of the vehicle body, effectively disperse the clamping force of the carrying gripper 100 on the vehicle body, thereby reducing the risk of stress concentration of the carrying gripper 100 when carrying the vehicle body, and improving product quality. Moreover, in the second direction, the third clamping block 133 and the fourth clamping block 134 are arranged at intervals on the frame 110, which can also provide support points at multiple positions of the vehicle body side wall. This multi-point support method significantly enhances the stability of the gripper during the carrying process, reducing the risk of side wall shaking or falling off.

[0057] During the operation of the carrying gripper 100, the vehicle body may be turned over. By arranging the third clamping block 133 and the fourth clamping block 134 at intervals in the second direction, the carrying gripper 100 can better clamp the vehicle body during the turning over of the vehicle body, improving the stability of the carrying gripper 100 clamping the vehicle body.

[0058] In actual production, the shape and size of the vehicle body side wall are various and complex. The third clamping block 133 and the fourth clamping block 134 arranged at intervals can better adapt to these different shapes and ensure that the gripper can firmly hold the side wall. The third clamping block 133 and the fourth clamping block 134 arranged at intervals enable the carrying gripper 100 to quickly find and lock the appropriate clamping position when approaching the vehicle body side wall, thereby shortening the preparation time before carrying.

[0059] The position of at least one of the third clamping block 133 and the fourth clamping block 134 on the frame 110 is adjustable, so that the carrying gripper 100 can adapt to vehicle body side walls of different sizes and shapes, improving the flexibility and efficiency of carrying, expanding the application range of the carrying gripper 100, and reducing the need to set up a carrying gripper 100 for each vehicle model. This reduces the space occupied by the carrying gripper 100 in the factory, improves the space utilization of the factory, improves production efficiency, and reduces production costs.

[0060] Please refer to Figures 1 to 3 In this embodiment, at least one of the first clamping block 131 and the second clamping block 132 is adjustable in position on the frame 110 in the second direction, or / and at least one of the third clamping block 133 and the fourth clamping block 134 is adjustable in position on the frame 110 in the first direction.

[0061] In the second direction, the positions of at least one of the first clamping block 131 and the second clamping block 132 on the frame 110 are adjustable, that is, the positions of the first clamping block 131 and the second clamping block 132 in the second direction can be adjusted. In the first direction, the positions of at least one of the third clamping block 133 and the fourth clamping block 134 on the frame 110 are adjustable, that is, the positions of the third clamping block 133 and the fourth clamping block 134 in the first direction can be adjusted. In this way, the carrying gripper 100 can adapt to different sizes and shapes of the body side, improve the flexibility and efficiency of carrying, expand the application range of the carrying gripper 100, so that it is not necessary to set up a carrying gripper 100 for each vehicle type, reduce the space occupied by the carrying gripper 100 in the factory, improve the space utilization rate of the factory, improve the production efficiency, and reduce the production cost.

[0062] Please refer to Figures 1 to 4 , Figure 4 The structure diagram of the positioning pin 120 provided by an embodiment of the present application is shown. In this embodiment, the positioning pin 120 includes a first positioning pin 121 and a second positioning pin 122. In the first direction, the first positioning pin 121 and the second positioning pin 122 are spaced apart on the frame 110.

[0063] In the first direction, the first positioning pin 121 and the second positioning pin 122 are spaced apart on the frame 110. The first positioning pin 121 and the second positioning pin 122 can ensure that the carrying gripper 100 achieves accurate positioning when grabbing the vehicle body. By limiting the degrees of freedom of the vehicle body in three-dimensional space, the positioning pin 120 can limit the position of the vehicle body to a certain range, thereby ensuring the accuracy of the carrying gripper 100 in grabbing the vehicle side.

[0064] The first positioning pin 121 and the second positioning pin 122 can prevent the carrying gripper 100 from moving or displacing when grabbing or moving objects, ensuring the stability of the structure and helping to reduce the problem of vehicle body loosening or falling off caused by external factors such as vibration and impact.

[0065] The first positioning pin 121 and the second positioning pin 122 are spaced apart on the frame 110, which can position and support different parts of the vehicle body, effectively dispersing the supporting force of the carrying gripper 100 on the vehicle body, thereby reducing the risk of stress concentration of the carrying gripper 100 when carrying the vehicle body and improving product quality. Moreover, in the first direction, the first positioning pin 121 and the second positioning pin 122 are spaced apart on the frame 110, which can also provide support points at multiple positions of the vehicle side, and this multi-point support mode significantly enhances the stability of the gripper during carrying, reducing the risk of side sway or falling off.

[0066] Please refer to Figures 1 to 5 , Figure 5A structural schematic diagram of the clamping block 130 provided in an embodiment of the present application is shown in FIG. 1. In this embodiment, the clamping block 130 is configured as a multi-layer structure and includes a base layer 135 and a protective layer 136 arranged on the side of the base layer 135 in the thickness direction. The base layer 135 is provided with a first recess 137, and the protective layer 136 is provided with a second recess 138. The first recess 137 and the second recess 138 define a clamping space for clamping the side wall of the vehicle body.

[0067] The protective layer 136 is arranged on the side of the base layer 135 in the thickness direction, i.e., the protective layer 136 is arranged on both sides of the base layer 135, and the side of the base layer 135 is covered by the protective layer 136. The first recess 137 and the second recess 138 define a space for clamping the vehicle body, and the vehicle body is clamped by the first recess 137 and the second recess 138, i.e., when the handling gripper 100 needs to clamp the vehicle body, the vehicle body will be in contact with the first recess 137 and the second recess 138 for clamping, and the position of the vehicle body can be fixed.

[0068] The first recess 137 and the second recess 138 define a clamping space for clamping the side wall of the vehicle body, which can increase the contact area between the clamping block 130 and the side wall of the vehicle body, thereby increasing the friction and making the clamping of the handling gripper 100 and the vehicle body more stable and less likely to loosen or fall off. The recess design on the clamping block 130 can make the installation and disassembly process more simple and fast. When the handling gripper 100 needs to clamp the side wall of the vehicle body, the corresponding parts can be inserted into the recess to complete the positioning and clamping. When the handling gripper 100 needs to be separated from the side wall of the vehicle body, the position of the clamping block 130 can be moved correspondingly so that the first recess 137 and the second recess 138 in the clamping block 130 are separated from the vehicle body.

[0069] Please refer to Figures 1 to 5 In this embodiment, the protective layer 136 is two and arranged on both sides of the base layer 135 in the thickness direction.

[0070] The protective layer 136 includes a first protective layer 136A and a second protective layer 136B, which are arranged on both sides of the base layer 135 in the thickness direction of the clamping block 130. The first protective layer 136A and the second protective layer 136B can provide more comprehensive protection for the base layer 135, reduce the probability of failure of the handling gripper 100, improve the stability of the factory operation, and thus improve the production efficiency.

[0071] Please refer to Figures 1 to 5 In this embodiment, at least part of the inner wall of the first recess 137 protrudes from the inner wall of the second recess 138 in the direction toward the clamping space.

[0072] At least part of the inner wall of the first groove 137 protrudes from the inner wall of the second groove 138, that is, at least part of the inner wall of the first groove 137 will be in contact with the vehicle body first during the clamping of the vehicle body by the carrying gripper 100. For example, the bottom wall of the first groove 137 can protrude from the second groove 138.

[0073] Specifically, at least part of the inner wall of the first groove 137 protrudes from the inner wall of the second groove 138, and the first groove 137 is in contact with the vehicle body first during the clamping of the vehicle body by the carrying gripper 100. The first groove 137 can act as a buffer for the vehicle body, which can reduce the probability of failure of the carrying gripper 100, improve the stability and reliability of the carrying gripper 100, and improve the operating efficiency of the factory.

[0074] Please refer to Figures 1 to 5 In this embodiment, the hardness of the base layer 135 is less than the hardness of the protective layer 136.

[0075] For example, the material of the base layer 135 can be polyurethane, and the material of the protective layer 136 can be a metal material.

[0076] When the carrying gripper 100 clamps the vehicle body, the vehicle body will be extruded with the base layer 135 because the base layer 135 is in contact with the vehicle body first, and the base layer 135 is deformed by extrusion, forming a clamping force, so that the carrying gripper 100 can clamp and fix the vehicle body on the carrying gripper 100.

[0077] The hardness of the base layer 135 is less than the hardness of the protective layer 136, which can protect the clamping block 130 from direct contact and collision with the vehicle body, reduce the probability of failure of the clamping block 130, improve the stability and reliability of the carrying gripper 100, and improve the operating efficiency of the factory.

[0078] Please refer to Figures 1 to 5 In this embodiment, the positioning pin 120 includes a body portion 123 and a plurality of movable portions 124 arranged on the body portion 123, and the movable portions 124 are movable relative to the body portion 123 along the radial direction of the positioning pin 120.

[0079] The positioning pin 120 comprises a body part 123 and a plurality of movable parts 124 arranged on the body part. The plurality of movable parts 124 can be arranged on the body part 123 at intervals along the circumference of the body part 123, and are movable relative to the body part 123 along the radial direction of the positioning pin 120. Before the carrying gripper 100 clamps the vehicle body, the plurality of movable parts 124 can be folded together along the radial direction of the positioning pin 120, so that the positioning pin 120 can be efficiently inserted into the positioning hole of the vehicle body, reducing the probability of collision between the positioning pin 120 and the vehicle body, and improving the carrying efficiency and carrying quality. After the positioning pin 120 is inserted into the positioning hole of the vehicle body, the plurality of movable parts 124 can be away from each other along the radial direction of the positioning pin 120, so that the plurality of movable parts 124 can be in contact with the vehicle body to support the vehicle body, increasing the contact and support area between the positioning pin 120 and the vehicle body, and improving the positioning accuracy of the carrying gripper 100.

[0080] The positioning pin 120 can provide positioning and support for the carrying gripper 100. The plurality of movable parts 124 are movable relative to the body part 123 along the radial direction of the positioning pin 120, which can reduce the occurrence of single-point force at the positioning hole of the vehicle body, and reduce the probability of deformation of the vehicle body due to insertion of the positioning pin 120.

[0081] In some embodiments, a plurality of clamping grooves are arranged at intervals on the plurality of movable parts 124 along the axial direction of the positioning pin 120, and the groove width of the clamping grooves can be 7 mm. During the process of clamping the vehicle body by the carrying gripper 100, the plurality of movable parts 124 of the positioning pin 120 are in abutment with the positioning hole of the vehicle body. The arrangement of the plurality of clamping grooves on the movable parts 124 can clamp the positioning hole of the vehicle body, reduce the probability of relative movement between the positioning hole and the positioning pin 120, and improve the stability and reliability of the carrying gripper 100.
