Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0029] Example 1

[0030] In a typical implementation of the present invention, Figure 1 As shown, a picking and placing device for welding a door cover inner panel assembly is provided, comprising a driving cylinder 1, a linking mechanism 3 and a supporting mechanism 2, wherein one end of the linking mechanism 3 is connected to the supporting mechanism 2, and the other end of the linking mechanism 3 is connected to a base plate, the driving cylinder 1 is arranged at the bottom of the supporting mechanism 2, a workpiece to be welded is placed on the supporting mechanism 2, and the driving cylinder 1 drives the supporting mechanism 2 to switch between a horizontal state and an inclined state.

[0031] In this embodiment, a plurality of guide rods 4 are arranged at the bottom of the support mechanism 2, and the guide rods 4 are fixed on the base plate. There are three guide rods 4, and the three guide rods 4 are distributed in a triangular shape around the driving cylinder 1, which has supporting stability. The guide rods are arranged to support and guide the support mechanism 2. Figure 2 As shown, the guide rod 4 includes a fixed rod 401, a sleeve 402 and a telescopic rod 403. The fixed rod 401 is fixed on the base plate, the upper end of the fixed rod is connected to the sleeve 402, and the telescopic rod 403 is arranged in the sleeve 402. When the driving cylinder 1 drives the supporting mechanism 2 to rise and fall, the telescopic rod 403 can be extended and recovered from the sleeve 402.

[0032] like Figure 3 As shown, the support mechanism 2 is a frame structure formed by welding a plurality of rods, the size of the frame structure is adapted to the size of the workpiece to be welded, and is used to support the welded workpiece. Specifically, the rods include a horizontal rod 202 and a vertical rod 201, and the horizontal rod 202 and the vertical rod 201 are arranged crosswise and vertically to form a U-shaped structure in the middle of the support mechanism.

[0033] Furthermore, a connecting plate 205 is fixedly installed at the bottom of the square-shaped structure, and the connecting plate 205 is connected to the driving cylinder 1 and the guide rod. In the actual production process, those skilled in the art can arrange the rods of the supporting mechanism as needed to support the workpiece to be welded.

[0034] Furthermore, a positioning block 203 is provided at the end of each rod, and the workpiece to be welded is positioned by the positioning block 203. Meanwhile, a corresponding positioning rod 204 can be provided according to the height of the workpiece to be welded.

[0035] like Figure 4 As shown, the link mechanism 3 includes an L-shaped fixing block 301 and a slider 302, and the slider 302 is provided with a long hole 305. One end of the L-shaped fixing block 301 is fixed to the base plate through the mounting hole 303, and the other end is mounted in the long hole 305 of the slider 302 through a first bolt 304. The first bolt 304 can move in the long hole 305 of the slider 302.

[0036] Furthermore, the end of the sliding block 302 is rotatably connected to the supporting mechanism 2 via a second bolt 306. The connecting mechanism 3 is provided to achieve that when the driving cylinder 1 drives the supporting mechanism 2 to move upward, it tilts.

[0037] The substrate in this embodiment can be the ground or the working surface of a workbench, which is a horizontal surface. Figure 1 In order to make it easier to see the structure of the device, the angle is adjusted. In actual use, Figure 1 The driving cylinder and the guide rod are arranged downward, that is, toward the substrate. The end of the guide rod is fixed to the substrate to support the supporting mechanism. The driving cylinder is installed on the base to provide a reaction force for the driving cylinder. The base is fixed on the substrate.

[0038] The working principle of the door cover inner panel assembly welding pick-and-place device provided in this embodiment is as follows:

[0039] The driving cylinder extends to make the support mechanism in an inclined state. The operator places the door inner panel assembly parts on the support mechanism of the device, and then transmits the information to the cylinder through the operation button. The cylinder contracts and pulls the support mechanism. Under the guidance of the link mechanism and the guide rod, the device returns to a horizontal state to achieve automatic welding by the robot. After the welding operation is completed, the driving cylinder extends again, and the support mechanism is guided by the guide rod and the link mechanism to achieve jacking and form an angle with the BASE plate, which is convenient for manual removal.

[0040] Compressed air is used to drive the cylinder to provide different position states for the support mechanism. In the retracted state, the robot can automatically weld the parts on the fixture. In the open state, it is convenient for manual picking and placing of parts, so that workers do not need to bend down during the picking and placing process.

[0041] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
