Description

Technical Field

[0001] This utility model relates to the field of end effectors, specifically a support rod structure for an end effector. Background Technology

[0002] An end effector consists of a crossbar and multiple suction cups connected to the crossbar. The positions of the suction cups are matched to the shape of the material, thus accurately moving materials of a specified shape. In existing end effectors, the suction cups are generally fixed to both sides of the crossbar by support rods. When the shape of the material changes, the length of the support rods needs to be changed in time so that the suction cups are repositioned at a different distance from the crossbar to accurately fit the material with the changed size. This structure means that the end effector can only be used with materials of a specified shape. When moving materials of different shapes, the end effector needs to be replaced or modified, resulting in a narrow application range and low utilization rate of existing end effectors, and low efficiency in using them to move materials of different shapes. Utility Model Content

[0003] The purpose of this invention is to provide a support rod structure for an end effector, which can solve the technical problem of low adaptability of existing end effectors to different shaped plates. By extending and retracting the rod, the position of the suction cups at multiple positions can be adjusted, thereby quickly adapting to different plate shapes, reducing the frequency of replacement, improving the adaptability of the end effector, and increasing the efficiency of handling and moving different plates.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] An end effector support rod structure includes a rod body with a cavity inside. End caps are movably connected to both ends of the cavity. Multiple guide surfaces are provided on the side of the rod body. Friction parts are provided on the side of the rod body. A drag chain groove for accommodating an air passage is provided on the top of the rod body.

[0006] Furthermore, the longitudinal section of the rod is polygonal, and the guide surface has at least three sides of a polygon.

[0007] Furthermore, the longitudinal section of the cavity is a trapezoid that is wider at the top and narrower at the bottom.

[0008] Furthermore, bolt holes are provided at both ends of the cavity, and the end cap is fixed in the bolt holes by bolts.

[0009] Furthermore, the area inside the rod body located outside the cavity and the drag chain groove is also provided with multiple irregularly shaped cavities.

[0010] Furthermore, the irregularly shaped cavity is symmetrically arranged between the two sides of the cable chain groove and the top of the cavity.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The structure of this utility model has multiple guide surfaces on the side of the rod, which slide in contact with the crossbar of the end effector. At the same time, a friction part is provided on the side of the rod to cooperate with the crossbar of the end effector. When adjusting the position of the suction cup at the end of the rod, it is only necessary to slide the rod laterally to move it relative to the crossbar of the end effector. During the sliding process, the cooperation of multiple guide surfaces and the crossbar makes the rod maintain the stability of the sliding, thereby making the adjustment of the suction cup position more accurate and stable. After the adjustment is in place, the position of the rod is limited by the cooperation of the friction part and the crossbar, which further ensures the stability and convenience of adjusting the suction cup position. This makes the end effector more accurate and efficient in adapting to different shaped plates, and greatly improves the efficiency and convenience of the end effector in moving and transporting different shaped plates.

[0013] 2. The rod body has an internal cavity. The cavity design can greatly reduce the weight of the rod body while maintaining the overall structural strength. When there are many rods in the end effector, it can greatly reduce the amount of material used for the rods and reduce the overall cost of the device. The end caps at both ends of the cavity can be used to seal the cavity and prevent external debris and impurities from entering the cavity. The drag chain groove at the top of the rod body can be used to store the air passage for the suction cup, ensuring the normal operation of its adsorption function during the adjustment of the suction cup position.

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0019] Reference Figure 1This utility model describes a support rod structure for an end effector. The main structure includes a rod body 1, which is mounted on the crossbar of the end effector. The rod body 1 is made entirely of aluminum to ensure sufficient structural strength. A suction cup is provided at the end of the rod body 1, which supports the suction cup. The relative position of the suction cup can be adjusted by the sliding movement of the rod body 1 relative to the crossbar of the end effector, thereby quickly and accurately adsorbing and fitting the suction cup onto materials of different shapes. Specifically, a driving device such as a motor is used to drive the sliding movement of the rod body 1 relative to the crossbar of the end effector. The specific structure is not limited; it can be a gear and toothed plate structure or a lead screw and nut driving structure. The suction cup uses air extraction to create a vacuum for adsorbing the material, thus achieving fixation of the material after it is attached to the plate. The material handling operation utilizes multiple suction cups on the end effector, whose positions are adapted to the shape of the material, enabling accurate handling of materials of different shapes. The rod 1 has an internal cavity 2 that extends through both ends. The cavity 2 reduces the weight of the rod 1 while maintaining its structural strength. When a large number of rods 1 are used on the end effector, the material usage can be significantly reduced, thus saving on the overall cost of the device. End caps 3 are movably connected to both ends of the cavity 2, sealing it to prevent debris and impurities from entering and ensuring the cleanliness of the cavity. This prevents the weight of the rod 1 from changing due to debris entry and ensures smooth sliding movement of the rod 1. The rod body 1 has multiple guide surfaces 4 on its side. These guide surfaces 4 prevent the rod body 1 from wobbling or misaligning when it moves laterally relative to the crossbar of the end effector, thus ensuring the stability of the sliding structure of the rod body 1. This makes the position of the suction cup at the end of the rod body 1 more accurate and stable after adjustment, improving the accuracy of its fit with the shape of the plate. The rod body 1 also has a friction part 5 on its side. This friction part 5 can position the rod body 1 after it has slid into place by cooperating with the crossbar of the end effector, preventing further movement and ensuring the stability of the rod body 1 after sliding adjustment. Preferably, the crossbar of the end effector has a through guide hole, and the rod body 1 is slidably connected within the guide hole. The guide surfaces 4 slide in contact with the sidewall of the guide hole, and the shape of the guide hole is consistent with the shape of the rod body 1. The longitudinal cross-sectional shape of rod 1 is adapted to ensure accurate contact between guide surface 4 and the sidewall of guide hole, improving the robustness of the relative sliding structure of rod 1. A locking block is provided inside the guide hole to cooperate with friction part 5. The cooperation between the locking block and friction part 5 can accurately achieve the positioning operation of rod 1, further ensuring the robustness of rod 1 structure. Friction part 5 is a toothed plate. The locking block is vertically and slidably connected. The locking block and toothed plate are meshed. When rod 1 slides, the locking block disengages from the toothed plate through vertical sliding. After rod 1 slides to the desired position, the locking block resets through vertical sliding and re-engages with the toothed plate, making the locking and limiting of rod 1 more accurate and convenient. This structure allows for rapid sliding adjustment of the position of multiple rods 1 according to the shape of the plate.This allows the multiple suction cups to be quickly positioned to match the shape of the material, eliminating the need to modify or adapt the end effector by replacing rods of different lengths 1. This improves the adaptability of the end effector to different shaped materials, saves modification or replacement time, and enhances the convenience and efficiency of moving materials of different shapes. The top of the rod 1 is equipped with a cable chain groove 6 to accommodate the air path. A cable chain is installed in the cable chain groove 6 to support the air path, which is connected to the suction cups. This ensures the normal operation of the suction function during suction cup position adjustment and guarantees the accuracy of moving materials of different shapes.

[0020] Preferably, the longitudinal section of the rod 1 is a polygon, and the guide surface 4 has at least three sides of the polygon. The polygonal structure allows the rod 1 to have multiple contact surfaces, at least three of which are guide surfaces 4. The cooperation of the multiple guide surfaces 4 can further prevent the relative swaying of the rod 1 and further improve the stability of the sliding structure of the rod 1.

[0021] Preferably, the longitudinal section of the cavity 2 is a trapezoid that is wider at the top and narrower at the bottom. Specifically, the cavity 2 is located in the lower half of the rod 1. This structure allows the shape of the cavity 2 to be fully adapted to the shape of the polygonal rod 1, which is wider in the middle and narrower at both ends, thereby increasing the area of ​​the cavity 2, increasing the range of hollowing, and further reducing the weight of the rod 1.

[0022] Preferably, bolt holes 7 are provided at both ends of the cavity 2. Specifically, circular plates are provided at both ends of the cavity 2, and bolt holes 7 are opened on the circular plates. The end cover 3 is fixed in the bolt holes 7 by bolts. This structure allows the end cover 3 to be detachably connected to the end of the cavity 2 through the cooperation of bolts and bolt holes 7, making the disassembly and assembly of the end cover 3 more efficient and convenient.

[0023] Preferably, the area inside the rod body 1 outside the cavity 2 and the cable chain groove 6 is provided with multiple irregular cavities 8. The arrangement of multiple irregular cavities 8 can further hollow out the area outside the cavity 2 and the cable chain groove 6 on the rod body 1, further reducing the weight of the rod body 1, reducing the amount of material used and the overall cost of the device.

[0024] Preferably, the irregular cavity 8 is symmetrically arranged between the two sides of the cable chain groove 6 and the top of the cavity 2. This structure can make full use of the space between the cable chain groove 6 and the cavity 2. The irregular cavity 8 is used to hollow out the space between the two, further reducing the overall weight of the rod 1.

[0025] Working Principle: This invention features multiple guide surfaces 4 on the side of the rod 1 that slide in conjunction with the end effector crossbar. Simultaneously, a friction part 5 is provided on the side of the rod 1 to cooperate with the end effector crossbar. When adjusting the position of the suction cup at the end of the rod 1, simply slide the rod 1 laterally to move it relative to the end effector crossbar. During this sliding process, the cooperation of the multiple guide surfaces 4 with the end effector crossbar ensures the stability of the rod 1's sliding motion, thereby making the suction cup position adjustment more accurate and stable. After adjustment, the friction part 5, in cooperation with the end effector crossbar, limits the position of the rod 1, further ensuring the stability and convenience of suction cup position adjustment. The end effector's adaptability makes it more accurate and efficient to fit different shaped plates, greatly improving the efficiency and convenience of moving and handling different shaped plates. A cavity 2 is provided inside the rod 1. The cavity 2 can greatly reduce the weight of the rod 1 while maintaining the overall structural strength of the rod 1. When there are many rods 1 in the end effector, the amount of material used for the rod 1 can be greatly reduced, thus reducing the overall cost of the device. The end caps 3 at both ends of the cavity 2 can be used to seal the cavity and prevent external debris and impurities from entering the cavity 2. The drag chain groove 6 at the top of the rod 1 can be used to store the air passage for the suction cup, ensuring the normal operation of its adsorption function during the adjustment of the suction cup position.
