Description

Technical Field

[0001] This utility model relates to the field of transfer equipment, specifically an adsorption and gripping device. Background Technology

[0002] In the field of automation, product transfer typically involves two methods: either using adsorption or clamping alone, or combining adsorption and clamping. Existing structures combining adsorption and clamping employ grippers on both sides of the suction cup assembly. While this method allows for simultaneous adsorption of the product's top surface and clamping of its sides using both adsorption and clamping components, the risk of the product accidentally falling during the gripping process remains.

[0003] Therefore, it is necessary to provide an adsorption and gripping device. Summary of the Invention

[0004] The present invention provides an adsorption and gripping device that effectively solves the problem of insufficient safety requirements when transferring products using existing transfer equipment.

[0005] The technical solution adopted in this utility model is:

[0006] The adsorption gripping device includes a fixed frame, a cylinder gripper and an adsorption assembly. The adsorption assembly includes several suction cups mounted on the fixed frame and a vacuum generator mounted on the fixed frame and connected to the suction cups. The cylinder gripper includes a cylinder body mounted on the upper surface of a mounting plate, two grippers symmetrically mounted on the cylinder body and driven by the cylinder body, and a support column horizontally mounted on the opposite side of the grippers.

[0007] Furthermore, the support columns located on the two grippers are staggered, and the support columns are cylindrical.

[0008] Furthermore, the gripper includes a horizontal support plate with one end set at the cylinder output end, a side plate set at the other end of the horizontal support plate, and a rubber pad set inside the side plate. The side plate is provided with a mounting groove, the rubber pad is set in the mounting groove, the rubber pad is also provided with a countersunk hole, the side plate is provided with a No. 1 screw hole corresponding to the countersunk hole, and the rubber pad is connected to the side plate by bolts.

[0009] Furthermore, the fixing frame is also provided with several positioning posts, the lower end of which is higher than the lower end of the suction cup.

[0010] Furthermore, the fixing frame is also provided with a through hole, and the fixing frame is also provided with a mounting bracket and an infrared photoelectric switch mounted on the mounting bracket. The infrared photoelectric switch senses the product through the through hole.

[0011] Furthermore, the horizontal support plate has a second screw hole at its end, and the side plate has a vertically extending waist-shaped groove. The second screw hole corresponds to the waist-shaped groove, and the horizontal support plate is bolted to the side plate.

[0012] Furthermore, the length of the support column is not greater than the stroke of the gripper, and when the two grippers are open, the support column is located on the outside of the fixing frame.

[0013] The beneficial effects of the utility model are as follows: by setting support columns on opposite sides of the two grippers, the support columns can support the lower end of the product when it accidentally detaches from the grippers and suction cups, which can effectively achieve the stability and safety of product handling.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, the adsorption and gripping device provided in the embodiment of this application has a structure including a fixed frame 1, a cylinder gripper and an adsorption assembly. The adsorption assembly includes a plurality of suction cups 2 disposed on the fixed frame 1 and a vacuum generator 3 disposed on the fixed frame 1 and connected to the suction cups 2. The cylinder gripper includes a cylinder body 4 disposed on the upper surface of the mounting plate, two grippers 5 symmetrically disposed on the cylinder body 4 and driven by the cylinder body 4, and a support column 6 horizontally disposed on the opposite side of the grippers 5.

[0020] In actual use, the product to be transferred is placed at the workstation. The adsorption and gripping device of this application is installed on an external robotic arm and controlled by a PLC control system together with the external robotic arm. When transferring the product, the suction cup 2 first contacts the upper surface of the product. Then, the vacuum generator 3 draws a vacuum, causing the suction cup 2 to adsorb the product from the upper surface. Then, the robotic arm drives the adsorption and gripping device of this application to a certain height, for example, 10cm. The cylinder 4 drives the two grippers 5 to move towards each other, so that the two grippers 5 clamp the product from both sides. The support column 6 extends into the lower surface of the product. At this time, the support column 6 maintains a distance of 1 to 2 mm from the lower surface of the product. When it is necessary to place the product, the cylinder 4 first drives the two grippers 5 to open, so that the product is no longer in contact with the grippers 5. The support column 6 retracts from the corresponding position of the lower surface of the product. Then, the robotic arm mechanically drives the adsorption and gripping device of this application to move down. After the product is placed in place, the vacuum generator 3 turns off the vacuum, so that the suction cup 2 is no longer in contact with the product.

[0021] In the above design, the structural design and specific implementation of the adsorption and gripping device can effectively achieve the stability and safety of product handling.

[0022] Specifically: the support columns 6 located on the two grippers 5 are staggered, and the support columns 6 are cylinders.

[0023] In actual use, when the grippers 5 stably hold the product on both sides, the support column 6 does not directly contact the lower end of the product. When the two grippers 5 accidentally detach from the product and the product accidentally detaches from the suction cup 2, the product is supported by the support column 6.

[0024] In the above design, the support columns 6 of the two grippers 5 are staggered, so that when the product accidentally detaches, after the lower end face of the product comes into contact with the support column 6, the support columns 6 on both sides can fill the gap between the support columns 6 on the other side, increasing the contact area with the lower end face of the product.

[0025] Specifically: such as Figure 2 and Figure 3 As shown, the gripper 5 includes a horizontal support plate 51 with one end set at the output end of the cylinder 4, a side plate 52 set at the other end of the horizontal support plate 51, and a rubber pad 53 set inside the side plate 52. The side plate 52 is provided with a mounting groove 501, the rubber pad 53 is set in the mounting groove 501, the rubber pad 53 is also provided with a countersunk hole, and the side plate 52 is provided with a No. 1 screw hole corresponding to the countersunk hole. The rubber pad 53 is connected to the side plate 52 by bolts.

[0026] In actual use, when it is necessary to clamp the two sides of the product, the rubber pad 53 contacts the side of the product. When it is necessary to replace the rubber pad 53, remove the bolt, take the rubber pad 53 out of the mounting groove 501, replace it with a new rubber pad 53 and place it in the mounting groove 501, and then use bolts to fix the rubber pad 53 to the side plate 52 through the countersunk hole and the No. 1 screw hole.

[0027] In the above design, the structural design and specific implementation of the gripper 5 can effectively achieve the function of enhancing the buffer between the product and the side of the product by using the rubber pad 53 when clamping the product. At the same time, the rubber pad 53 has a rough surface, which can increase the friction with the side of the product, making it easier to clamp the product.

[0028] Specifically: such as Figure 1 As shown, the fixing frame 1 is also provided with several positioning posts 7, the lower end of the positioning posts 7 being higher than the lower end of the suction cup 2. It should be noted that positioning holes are provided on the upper surface of the product.

[0029] In actual use, after the fixing frame 1 moves down, the positioning post 7 extends into the positioning hole of the product, and then the suction cup 2 contacts the upper surface of the product to adsorb the product.

[0030] In the above design, the accuracy of picking up the product can be improved by setting positioning holes.

[0031] Specifically: such as Figure 1 As shown, the fixing frame 1 is also provided with a through hole 101, and the fixing frame 1 is also provided with a mounting bracket and an infrared photoelectric switch 8 mounted on the mounting bracket. The infrared photoelectric switch 8 senses the product through the through hole 101.

[0032] In actual use, after the infrared photoelectric switch 8 senses the position of the product, the PLC control system controls the suction cup 2 to adsorb the product.

[0033] In the above design, the infrared photoelectric switch 8 is set to sense the product. When the adsorption and gripping device of this application moves into place and the infrared photoelectric switch 8 senses the product, the suction cup 2 will adsorb the product.

[0034] Specifically: such as Figure 2 and Figure 3 As shown, the horizontal support plate 51 has a second screw hole 510 at its end, and the side plate 52 has a vertically extending waist-shaped groove 520. The second screw hole 510 corresponds to the waist-shaped groove 520, and the horizontal support plate 51 is bolted to the side plate 52.

[0035] In actual use, the side plate 52 is adjusted so that the second screw hole 510 corresponds to different positions of the waist groove 520. Then, the bolt is threaded through the waist groove 520 and threaded to the second screw hole 510 to change the height of the side plate 52, which is convenient for adapting to products of different sizes.

[0036] In the above design, the structural design of the side plate 52 and the horizontal support plate 51 facilitates the adjustment of the height of the side plate 52, thereby making it easier for the cylinder gripper to adapt to products of different heights.

[0037] Specifically: the length of the support column 6 is not greater than the stroke of the gripper 5, and when the two grippers 5 are open, the support column 6 is located on the outside of the fixing frame 1.

[0038] In actual use, when the two grippers 5 open, the support column 6 moves to a position outside the two sides of the fixed frame 1.

[0039] In the above design, the structural design and specific implementation of the support column 6 can effectively prevent the support column 6 from scratching the sides of the product when adsorbing the product.

[0040] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
