[0027] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0028] A collaborative robot capable of assembly operations, such as Figure 1-Figure 10As shown, it includes a moving vehicle 1, a limiting block 2, a placing table 3, a supporting plate 4, a limiting frame 5, a first telescopic spring 6, a fixed base 7, a mechanical arm 8, a plug rod 9, a screw 10, a sliding block 11, a second telescopic spring 12, an extrusion block 13 and a limiting ball 14. The upper sides of the front and rear parts of the moving vehicle 1 are connected with limiting blocks 2, a placing table 3 is placed on the moving vehicle 1, and the limiting blocks 2 are in contact with the placing table 3. The placing table 3 is L-shaped, and the front and rear sides of the placing table 3 are connected with supporting plates 4. The supporting plates 4 are slidably connected with limiting frames 5. The limiting frames 5 are clamped with the limiting blocks 2 on the same side, and the limiting frames 5 are in contact with the placing table 3. The limiting frames 5 are provided with handles for convenient hand-gripping and pulling the limiting frames 5 to move. The limiting frames 5 are connected to the first telescopic spring 6 between the supporting plates 4 on the same side. A fixed base 7 is placed on the upper side of the rear part, and a mechanical arm 8 is connected to the upper middle side of the fixed base 7. The mechanical arm 8 consists of four joints. The left and right parts of the fixed base 7 are connected with an insertion rod 9, and the insertion rod 9 is in contact with the placement table 3. The inner side of the upper part of the insertion rod 9 is connected with a screw 10 through a thread. The screw 10 is provided with a handle for easy hand-holding and rotation of the screw 10. The lower part of the screw 10 is rotatably connected with a sliding block 11, and the sliding block 11 is slidably connected to the insertion rod 9 at the same longitudinal position. The inner side of the lower part of the insertion rod 9 is slidably connected with an extrusion block 13, and the lower part of the extrusion block 13 is conical. A second telescopic spring 12 is connected between the extrusion block 13 and the sliding block 11 at the same longitudinal position. Two left and right limiting balls 14 are placed on the lower part of the insertion rod 9, and the limiting balls 14 are clamped with the placement table 3.

[0029] When a collaborative robot is needed during product production, the present device can be used. By starting the mobile vehicle 1, the present device is moved to the place where the product is produced. After reaching the designated position, the mobile vehicle 1 is closed, so that the present device can be moved, which is convenient for moving to different places for use and has wide adaptability. Then, the placement table 3 is placed on the mobile vehicle 1. The placement table 3 is L-shaped, so that the limiting frame 5 contacts the limiting block 2, so that the limiting frame 5 moves along the support plate 4. The first telescopic spring 6 is stretched and then rebounds, so that the limiting frame 5 moves in the opposite direction and engages with the limiting block 2, thereby limiting the placement table 3. Then, the fixed base 7 is placed on the placement table 3, so that the insertion rod 9 contacts the placement table 3, and then the screw 10 is rotated by the handle. Under the action of the thread, the screw 10 moves, thereby pushing the sliding block 11 to move, and the second telescopic spring 12 is squeezed, so that the squeezing block 13 moves, thereby pushing the limiting ball 14 to move, so that the limiting ball 14 is engaged with the placement table 3. The lower part of the squeezing block 13 is conical, which is convenient for pushing the limiting ball 14 out, thereby limiting the fixed base 7 is fixed, and then the mechanical arm 8 is installed. After the installation is completed, the mechanical arm 8 is started to operate to clamp, transport and place the materials. The mechanical arm 8 is composed of four joints. After use, the mechanical arm 8 is closed, and then the screw rod 10 is rotated in the opposite direction by the handle. Under the action of the thread, the screw rod 10 moves in the opposite direction, thereby driving the sliding block 11 to move in the opposite direction, the second telescopic spring 12 rebounds, and the extrusion block 13 moves and resets. Then the fixed base 7 is lifted, so that the insertion rod 9 is separated from the placement table 3. During the movement, the limiting ball 14 moves and resets, and then the limiting frame 5 is pulled by the handle to move, the first telescopic spring 6 is stretched, so that the limiting frame 5 is separated from the limiting block 2, and then the placement table 3 is lifted and separated from the mobile vehicle 1, and then the limiting frame 5 is released. The first telescopic spring 6 rebounds, and the limiting frame 5 moves and resets, so that the device can be quickly assembled, which is convenient for the installation and disassembly of the placement table 3 and the mechanical arm 8, and it is convenient to replace the mechanical arm 8 of different specifications for use, improve the efficiency of assembly, and use it flexibly and conveniently. Then the mobile vehicle 1 can be operated to take the device away.
