Description

Technical Field

[0001] The utility model relates to vehicle decoration production equipment, in particular to a decoration grabbing device. Background Art

[0002] During the production of vehicle trims, parts need to be transferred between different workstations for finishing. Traditionally, trim transfer is accomplished manually. However, manual handling can lead to inconsistent trim appearance, such as deformation and dents caused by bumps and bumps. Furthermore, manual handling is inefficient, impacting overall production efficiency.

[0003] In order to improve production efficiency, automatic transfer is generally used in this field to transfer the decorative parts to the next workstation for further processing. In the prior art, a manipulator is used in conjunction with a clamping cylinder structure to achieve the transfer of decorative parts, such as the Chinese patent document with publication number CN217967042U. In this patent document, a clamping assembly is set at each end of the connecting assembly, and the clamping assembly mainly uses a clamping cylinder as a power source and cooperates with two clamping claws to clamp the decorative parts. This clamping structure requires a greater clamping force to keep the decorative parts and the clamping claws stable during the transfer of the decorative parts. As the clamping force of the clamping claws increases, the risk of deformation of the decorative parts also increases, resulting in a poor pass rate of the decorative parts. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a decorative part grabbing device, which can improve production efficiency and the qualified rate of decorative parts.

[0044] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0045] Because existing clamping structures require a strong clamping force to keep the trim and the clamping jaws stable during trim transfer, the risk of trim deformation increases with increasing clamping force, resulting in a low trim pass rate.

[0046] Please refer to Figures 1-6 A decorative part grabbing device includes a connecting assembly 1 and a grabbing mechanism 2; the connecting assembly 1 has at least two symmetrically arranged grabbing mechanisms 2 in a first direction; the grabbing mechanism 2 includes a driving member 21, a clamping jaw assembly 22, a support assembly 23, and a contoured pressure member 24; the contoured pressure member 24 and the driving member 21 are respectively connected to the support assembly 23; the clamping jaw assembly 22 includes a driving portion 221, a connecting portion 222, and a pressure portion 223 arranged in sequence; the connecting portion 222 is rotatably connected to the support assembly 23; the driving portion 221 is in transmission connection with the driving member 21, so that the pressure portion 223 can gradually approach or gradually move away from the contoured pressure member 24; a clamping space for clamping the decorative part 3 can be formed between the pressure portion 223 and the contoured pressure member 24. Preferably, the driving member 21 is a linear driving member 21, such as a linear cylinder, a linear push rod, etc.

[0047] In some embodiments, the connection side of the connecting component 1 is also provided with a quick-change mechanism for connecting to a robot arm. The quick-change mechanism includes a quick-change disk 11 and a positioning hole 12. The robot arm is electrically connected to all driving parts 21 through the quick-change disk 11, so that the connecting part 222 and the pressure part 223 can be controlled to cooperate in clamping or placing the ornament 3. The positioning hole 12 can improve the positioning efficiency between the connecting component 1 and the robot arm.

[0048] It is understood that the present invention achieves the clamping and release of the decorative part 3 by driving the jaw assembly 22 to rotate via the driving member 21, thereby changing the positional relationship between the jaw assembly 22 and the contoured pressing member 24. Due to the formation of the clamping space and the relatively rotatable connection between the connecting portion 222 of the jaw assembly 22 and the support assembly 23, a clamping space open only on one side is formed. In addition, the provision of the contoured pressing member 24 improves the stability of the decorative part 3 during the handling process, reduces the clamping force required for the decorative part 3, and thus prevents the decorative part 3 from being crushed during handling, thereby improving the product qualification rate. The connecting assembly 1 can be connected to a robot arm to achieve rapid handling of the decorative part 3, realize automated production, and improve production efficiency.

[0049] In some embodiments, the clamping jaw assembly 22 further includes a contoured support block 224; a driving portion 221, a connecting portion 222, and a pressure portion 223 are sequentially arranged to form a clamping jaw body 225; and the contoured support block 224 is connected to the end of the pressure portion 223 away from the driving portion 221. The clamping jaw body 225 is Z-shaped, and the contoured support block 224 has a groove 226 on the side facing the clamping space for limiting the position of the decorative part 3. The clamping jaw body 225 can be flipped by the control of the driving member 21. Because the connecting portion 222 of the clamping jaw body 225 is hinged to the support assembly 23, the positional relationship between the contoured support block 224 and the contoured pressure member 24 can be changed when the driving member 21 is extended or retracted, thereby enhancing reliability and improving the stability of the decorative part 3 during handling.

[0050] In some embodiments, when the distance between the pressure portion 223 and the contoured pressure member 24 is at its maximum, an acute angle is formed between the distribution direction of the pressure portion 223 and the pressure surface of the contoured pressure member 24, providing ample space for grasping the decorative part and shortening the grasping time. The distance between the pressure portion 223 and the contoured pressure member 24 depends on the extension length of the driver 21. Specifically, during the loading process, when the driver 21 extends, the contoured support block 224 gradually approaches the contoured pressure member 24. After the decorative part is stably clamped, the contoured support block 224 and the contoured pressure member 24 are arranged opposite each other. During the unloading process, when the driver 21 retracts, the contoured support block 224 gradually moves away from the contoured pressure member 24, and the decorative part 3 is released.

[0051] In some embodiments, the pressure portion 223 is movable within a movable plane. A sensor 25 is mounted on one side of the support assembly 23 that is parallel to the movable plane, with the sensing end of the sensor 25 facing the clamping space. Preferably, the sensor 25 is a photoelectric switch. The sensor 25 detects whether the decorative piece is being grasped and released, improving the accuracy of the grasping action. The movable plane refers to the plane formed when the pressure portion 223 is flipped.

[0052] In some embodiments, the fixed end of the driver 21 is fixedly connected to the support assembly 23 via a connecting frame 26, and the movable end of the driver 21 passes through the connecting frame 26 and is hingedly connected to the driving portion 221. The fixed end of the driver 21 is hingedly connected to the support member so that the driver 21 can change position as the clamping jaw assembly 22 flips, avoiding motion interference and providing sufficient space for the clamping jaw assembly 22 to move.

[0053] In some embodiments, a contoured positioning groove 241 is provided on one side of the contoured pressure member 24 facing the clamping space to improve the stability of the ornament. When the gripping mechanism 2 is tilted in different directions, it can ensure that the ornament is stably clamped, reducing the requirements for the clamping force of the ornament.

[0054] In some embodiments, the support assembly 23 includes a bracket 231 and an extension bracket 232. One end of the extension bracket 232 is connected to the side of the bracket 231 away from the contoured pressure member 24, and the other end of the extension bracket 232 is connected to the connecting assembly 1. The provision of the extension bracket 232 is used to increase the distance between the bracket 231 and the connecting assembly 1, thereby preventing interference between the connecting assembly 1 and the gripping mechanism 2 when gripping the decorative component, and providing more space for the gripping mechanism 2 to grasp the decorative component.

[0055] In some embodiments, at least two symmetrically arranged gripping mechanisms 2 constitute a group; along the second direction of the connecting assembly 1, there are at least two groups of gripping mechanisms 2 arranged sequentially. Specifically, since the decorative component 3 is mostly an elongated structure, the provision of at least two symmetrically arranged gripping mechanisms 2 can more stably grip the decorative component 3 and improve the stability of the decorative component 3 during handling.

[0056] In some embodiments, the connecting assembly 1 has a gripping side 14 and a connecting side 15; a gripping mechanism 2 is disposed on the gripping side. In the second direction, the gripping side 14 has two symmetrically arranged mounting bevels 141, with the two mounting bevels 141 forming an angle β greater than 90° and less than 180°. Each mounting bevel 141 is provided with a gripping mechanism 2. Preferably, the angle β is 140°; however, it may be 100°, 110°, 120°, 130°, 150°, 160°, or 170° depending on the actual situation. Each mounting bevel 141 is provided with at least two sets of gripping mechanisms 2. The robot can control the flipping of the connecting assembly 1 so that the two mounting bevels 141 alternately face the workstation, enabling the gripping mechanisms 2 on the two mounting bevels 141 to respectively grasp the processed decorative component 3 and replace the unprocessed decorative component 3, further improving processing efficiency.

[0057] In some embodiments, the connection assembly 1 is further provided with a radio frequency identification component 13. Specifically, an identification tag is provided on each product. The radio frequency identification component can identify whether the product being grasped is correct, thereby preventing product grasping errors during product switching on the production line. Preferably, the radio frequency identification component 13 is an RFID wireless radio frequency module.

[0060] In this embodiment, the clamping jaw assembly 22 further includes a contoured support block 224; a driving portion 221, a connecting portion 222, and a pressure portion 223, which are sequentially arranged to form a clamping jaw body 225; and the contoured support block 224 is connected to the end of the pressure portion 223 that is away from the driving portion 221. The clamping jaw body 225 is quasi-Z-shaped, and a groove 226 is defined on the side of the contoured support block 224 that faces the clamping space.

[0061] In this embodiment, when the distance between the pressure portion 223 and the contoured pressing member 24 is the largest, that is, when the clamping jaw assembly 22 is in the released state, the angle α formed between the distribution direction of the pressure portion 223 and the pressing surface of the contoured pressing member 24 is an acute angle; when the clamping jaw assembly 22 clamps the decorative piece 3, the distribution direction of the pressure portion 223 and the contoured pressing member 24 are parallel to each other, that is, Figure 4 The included angle α between the distribution direction of the pressure portion 223 and the pressing surface of the contoured pressing member 24 is 0.

[0062] In this embodiment, the pressure portion 223 is movable within a movable plane. A sensing element 25 is mounted on one side of the support assembly 23 that is parallel to the movable plane.

Two sets of gripping mechanisms 2 are disposed on each mounting bevel 141. With two symmetrically arranged gripping mechanisms 2 forming one set, four sets of gripping mechanisms 2 are disposed sequentially in the second direction of the connection assembly 1.
