Description

Technical Field

[0001] The utility model relates to the technical field of robot end effectors, in particular to a quick-install robot end effector. Background Art

[0002] The robot end effector is a device connected to the arm of an industrial robot, responsible for performing specific production tasks. It can complete operations such as grasping, handling, assembly, and testing. It is an important component of the automated production line. Through precise positioning and flexible operation, the end effector can improve production efficiency, ensure production quality, and reduce production costs.

[0003] The current robot end effector is usually connected to the end of the robot arm by bolts. However, when replacing different types of robot end effectors, the replacement efficiency is reduced and production is affected. Therefore, we propose a quick-install robot end effector. Utility Model Content

[0004] The purpose of the present utility model is to provide a quick-install robot end effector, which has the advantages of easy disassembly and installation of the robot end effector, improving the replacement and installation efficiency of the robot end effector, and reducing the impact on production. It solves the problem that the current robot end effector is usually connected to the end of the robot arm by bolt fixing, but when replacing different types of robot end effectors, the replacement efficiency is reduced, affecting production.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a quick-install robot end effector, comprising an end effector body, a fixed plate and a connecting plate, a connecting tube welded at the axial position on the upper surface of the fixed plate, and a flange plate welded at the end of the connecting tube, the upper surface of the fixed plate is formed into an array with four T-shaped slots and four through-holes equidistantly arranged, and the through-holes and the T-shaped slots are connected, the end effector body is fixedly mounted on the lower surface of the connecting plate, four T-shaped blocks are welded equidistantly in a circular array on the upper surface of the connecting plate, a sliding sleeve is slidably sleeved on the outer surface of the connecting tube, four plug-in blocks are welded equidistantly in a circular array on the lower surface of the sliding sleeve, and a coil spring is movably sleeved on the outer surface of the connecting tube at a position above the sliding sleeve.

[0006] Preferably, the upper surfaces of the four T-shaped blocks and the lower surfaces of the four insert blocks are all provided with rounded corners near the edges.

[0007] Preferably, the outer surfaces of the fixing plate and the connecting plate are both provided with alignment grooves.

[0008] Preferably, a positioning hole is provided at the axial center position of the lower surface of the fixing plate, and a positioning column is welded at the axial center position of the upper surface of the connecting plate.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] 1. The utility model is provided with an end effector body, a connecting plate, a T-block, a fixing plate, a through-hole, a T-slot, a sliding sleeve, a coil spring and an insert block, so as to facilitate the disassembly and installation of the robot end effector, improve the replacement and installation efficiency of the robot end effector, and reduce the effect of the impact on production. The fixing plate and the connecting pipe are fixed to the robot arm through a flange and bolts. When installing the end effector body, the four T-blocks on the connecting plate are respectively inserted into the four through-holes, and then the connecting plate is rotated, so that the four T-blocks respectively enter the four T When the insert block is rotated to above the through-hole, the elastic force of the coil spring causes the sleeve to drop, and the insert block is inserted into the through-hole, which limits the rotation of the T-block, thereby preventing the T-block from entering the through-hole and causing the connection disk and the fixed disk to separate. When disassembling the end effector body, lift the sleeve to separate the insert block and the through-hole, rotate the connection disk, and allow the T-block to enter the through-hole to separate the connection disk and the fixed disk, thereby completing the disassembly of the end effector body.

[0011] 2. The utility model provides an alignment groove. When the T-shaped block is inserted into the through-hole, the alignment grooves on the connecting plate and the fixing plate facilitate alignment of the T-shaped block and the through-hole, so that the T-shaped block can be inserted into the through-hole easily.

[0012] 3. The present invention provides positioning holes and positioning posts, which play a role in positioning the connection between the connecting disk and the fixed disk during the process of inserting the T-block into the through-hole, so as to facilitate the insertion of the T-block into the through-hole. At the same time, the positioning posts located inside the positioning holes also enhance the radial force strength between the fixed disk and the connecting disk after connection.

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figure 1-Figure 5 As shown, the utility model proposes a quick-install robot end effector, including an end effector body 1, a fixed plate 7 and a connecting plate 9. A connecting pipe 5 is welded at the axial position of the upper surface of the fixed plate 7, and a flange 4 is welded at the end of the connecting pipe 5. The connecting pipe 5 and the fixed plate 7 are fixed to the robot arm through the flange 4 and bolts. The upper surface of the fixed plate 7 is formed with four T-shaped slots 10 and four through-holes 11 at equal intervals, and the through-holes 11 are connected to the T-shaped slots 10. The cross-sectional view of the T-shaped slot 10 is "T"-shaped. The end effector body 1 is fixedly installed on the lower surface of the connecting plate 9. Four T-shaped blocks 12 are welded at equal intervals in a circular array on the upper surface of the connecting plate 9. The cross-section of the T-block 12 is in the shape of a "T". The T-block 12 is adapted to the T-slot 10, and the four T-blocks 12 are respectively located inside the four T-slots 10. The outer surface of the connecting tube 5 is slidably sleeved with a sleeve 3, and the lower surface of the sleeve 3 is equidistantly welded with four plug-in blocks 2 in a circular array. Rounded corners 14 are provided near the edge positions of the upper surfaces of the four T-blocks 12 and the lower surfaces of the four plug-in blocks 2. The setting of the rounded corners 14 facilitates the insertion of the T-block 12 and the plug-in blocks 2 into the through-port 11. The outer surface of the connecting tube 5 is movably sleeved with a coil spring 6 at a position above the sleeve 3. The elastic force of the coil spring 6 acts on the sleeve 3 to make the sleeve 3 move toward the fixed disk 7.

[0022] When the present invention is in use, the fixed plate 7 and the connecting pipe 5 are fixed to the robot arm by the flange plate 4 and bolts. When the end effector body 1 is installed, the four T-blocks 12 on the connecting plate 9 are respectively inserted into the four through-holes 11. Then, the connecting plate 9 is rotated, and the four T-blocks 12 are respectively entered into the four T-slots 10, thereby completing the installation and connection of the fixed plate 7 and the connecting plate 9. Then, the sliding sleeve 3 is rotated. When the insert block 2 is rotated to above the through-hole 11, the elastic force of the coil spring 6 causes the sliding sleeve 3 to descend, and the insert block 2 is inserted into the through-hole 11, which limits the rotation of the T-block 12, thereby preventing the T-block 12 from entering the through-hole 11 and causing the connecting plate 9 and the fixed plate 7 to separate. When the end effector body 1 is disassembled, the sliding sleeve 3 is lifted to separate the insert block 2 and the through-hole 11. The connecting plate 9 is rotated and the T-block 12 is entered into the through-hole 11. The connecting plate 9 and the fixed plate 7 are separated, and the disassembly of the end effector body 1 is completed.

[0023] Example 2

[0024] like Figure 1 、 Figure 3 and Figure 5 As shown, the utility model proposes a quick-install robot end effector. Compared with the first embodiment, this embodiment also includes alignment grooves 8 on the outer surfaces of the fixed disk 7 and the connecting disk 9, and a positioning hole 15 is provided at the axial position of the lower surface of the fixed disk 7. The positioning hole 15 is a through circular hole that extends from the lower surface of the fixed disk 7 to the upper surface. A positioning column 13 is welded at the axial position of the upper surface of the connecting disk 9. The positioning column 13 is cylindrical, and its length is greater than the thickness of the fixed disk 7.

[0025] In this embodiment, during the process of inserting the T-block 12 into the through-opening 11, the positioning column 13 is first inserted into the positioning hole 15, which plays a positioning role in the connection between the connecting disk 9 and the fixed disk 7. Then, the connecting disk 9 is rotated to align the two alignment grooves 8, which facilitates the insertion of the T-block 12 into the through-opening 11. At the same time, the positioning column 13 located inside the positioning hole 15 also enhances the radial force strength between the fixed disk 7 and the connecting disk 9 after connection.

[0026] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
