[0022] The present invention discloses a robot for assisting assembly of a housing 321 of an air conditioner of a new energy vehicle. Figure 1 and Figure 2 As shown, it includes a roller conveyor belt 1, and a moving seat 2 is provided as the roller conveyor belt 1 moves. The roller conveyor belt 1 is a transportation route for transporting and assembling automobile air conditioners. An auxiliary assembly robot for closing the air conditioner shell 321 is arranged at a fixed position of the roller conveyor belt 1 to assist the assembly personnel in operation. A lower shell 52 with an opening facing upward is fixed on the moving seat 2. As the moving seat 2 moves, the various components inside the air conditioner are installed and moved to the auxiliary assembly station. The auxiliary assembly station also includes a fixed suspension 31, and the suspension 31 is located above the roller conveyor belt 1. Four elastic recovery rollers 32 are fixed on the lower side of the suspension 31. The four elastic recovery rollers 32 are evenly distributed. The elastic recovery rollers 32 are wrapped with a suspension rope 33, and the suspension rope 33 extends downward. A vertical rod 34 is provided at the end of the suspension rope 33, and the ends of the four vertical rods 34 are fixed at the same time. There is a clamping seat 35 for clamping the upper shell 51, and a telescopic cylinder 36 that can be telescoped downward is fixedly provided on the suspension 31. A synchronous seat 37 is fixedly provided on the end of the telescopic cylinder 36. A positioning hole 371 for the suspension rope 33 to pass through is opened on the synchronous seat 37. The inner diameter of the positioning hole 371 matches the outer diameter of the vertical rod 34. A stopper 341 is provided on the upper end of the vertical rod 34. The telescopic cylinder 36 drives the synchronous seat 37 to move upward. The clamping seat 35 is in a free moving state and is used for the operator to move and clamp the placed upper shell 51. The telescopic cylinder 36 moves the synchronous seat 37 downward so that the upper end of the vertical rod 34 is inserted into the positioning hole 371. The stopper 341 is supported on the lower side of the synchronous seat 37. The lateral displacement of the clamping seat 35 is restricted. The clamping seat 35 is continuously moved downward so that the upper shell 51 clamped by the clamping seat 35 is docked with the upper shell 51 moved below the lower shell 52.

[0023] This auxiliary assembly robot is used to assist assemblers in closing up and down the air-conditioning housing 321 of a new energy vehicle. The synchronous seat 37 is retracted by the telescopic cylinder 36 on the suspension 31, so that the clamping seat 35 suspended by the vertical rod 34 and the suspension rope 33 can be held by the operator and moved up, down, left and right, so that it can be moved to the placement position of the upper shell 51 and clamped by the clamping seat 35. The elastic recovery roller 32 has an upward pulling force on the suspension rope 33, so that the operator can control the clamping seat 35 to clamp the upper shell 51 more easily and labor-savingly. After the clamping is completed, the upper shell 51 can be moved to the docking position. By moving the telescopic cylinder 36 downward, the synchronous seat 37 limits and pushes the vertical rod 34, the upper shell 51 moves vertically downward, the synchronous seat 37 pushes the blocking seat 341, the vertical rod 34 moves downward, and the upper shell 51 clamped by the clamping seat 35 is docked with the lower shell 52. This device is more labor-saving than manually carrying the upper shell 51 and the lower shell 52 to dock, and has a guiding effect, which improves the operational efficiency of the docking of the outer shell 321, avoids product backlogs caused by slow operation speed of the docking station of the outer shell 321, and improves the overall processing efficiency of automobile air-conditioning assembly.

[0024] In a further solution, Figure 4 As shown, the clamping seat 35 includes a receiving cavity 351 wrapped around the outer side of the upper shell 51, the receiving cavity 351 limits the lateral displacement of the upper shell 51, and a slide plate 352 is also provided in the inner side walls of the receiving cavity 351 for lateral movement, and a plurality of stop posts 353 are provided on the slide plate 352. A spring 354 is provided between the slide plate 352 and the clamping seat 35, and the slide plate 352 is supported by the spring 354 to penetrate into the receiving cavity 351 and block the position of the upper shell 51 with a protruding structure. To limit the vertical displacement of the upper shell 51, auxiliary moving handles 355 are also provided on both sides of the clamping seat 35, and a grip 356 for easy pinching is slidably provided inside the auxiliary moving handle 355. The grip 356 is connected to the slide plate 352 through a rod body, and is clamped on the upper shell 51. By holding the auxiliary moving handle 355 and pinching the grip 356, the clamping seat 35 is moved. After the clamping seat 35 is buckled on the upper shell 51, the grip 356 is released to fix the upper shell 51 in the clamping seat 35.

[0025] In this structure, an auxiliary moving handle 355 is provided to facilitate the operator to hold and move the clamping seat 35, and a receiving cavity 351 is provided to limit the clamped upper shell 51 laterally, and an elastic slide plate 352 and a stop column 353 structure are provided to stop the protruding position of the upper shell 51. It should be explained here that the shapes of various shells 321 are distinctive, so the shape of the receiving cavity 351 and the position of the stop column 353 need to correspond to the specific structure of the upper shell 51 to ensure that the clamping seat 35 can clamp the upper shell 51. Horizontal and vertical limits ensure that the clamping seat 35 fixes the upper shell 51. This structure is achieved by setting a handle 356 on the auxiliary movable handle 355. The operator only needs to pinch the handle 356 to retract the blocking column 353, so that the upper shell 51 can be placed in the accommodating cavity 351 from bottom to top, and then release the handle 356. The blocking column interface locks the upper shell 51. This structure is convenient for the operator's manual operation and conforms to the control habits. Furthermore, the component for controlling the extension and retraction of the telescopic cylinder 36 uses a remote control button, which can also be set on the auxiliary movable handle 355 to facilitate the operator's control.

[0026] In a further solution, Figure 1 and Figure 2 As shown, a conveying platform 4 for conveying the upper shell 51 is also provided above the roller conveyor belt 1. The conveying platform 4 is fixed in position and is located beside the suspension 31 to facilitate moving the clamping seat 35 to clamp the upper shell 51 conveyed to the end.

[0027] The conveying platform 4 is arranged at a position convenient for the operator to hold the upper shell 51. The upper shell 51 to be installed is moved to the holding position through the conveying platform 4 to implement the clamping operation of the upper shell 51. By setting up the conveying platform 4, instead of the frame for placing the upper shell 51, the secondary transportation of the upper shell 51 is omitted, thereby improving the installation efficiency of the air conditioner.

[0028] In a further solution, Figure 3 As shown, electric cylinders 11 are respectively provided on both sides of the roller conveyor belt 1, and the electric cylinders 11 are located below the suspension 31. Blocking heads 12 are provided at the ends of the electric cylinders 11. Blocking grooves 21 are provided on both sides of the movable seat 2. The electric cylinders 11 push the blocking heads 12 to fit into the blocking grooves 21, so that the movable seat 2 drives the lower shell 52 to move to a position where it is vertically docked with the upper shell 51.

[0029] By setting a blocking head 12 controlled by an electric cylinder 11, the movable seat 2 is paused and limited, and the upper shell 51 and the lower shell 52 are docked when the auxiliary clamping seat 35 moves vertically.

[0030] In a further embodiment, in a further embodiment, Figure 1 and Figure 2As shown, the upper end of the vertical rod 34 is chamfered to facilitate the vertical rod 34 to slide smoothly into the positioning hole 371.

[0031] In a further solution, Figure 5 As shown, the elastic recovery roller 32 includes a shell 321, a roller 322 is rotatably provided in the shell 321, the roller 322 is coaxially provided with a shaft 323, a torsion spring 324 is wound on the shaft 323, one end of the torsion spring 324 is fixedly connected to the roller 322, and the other end is fixedly connected to the inner side of the shell 321, the suspension rope 33 is wound on the roller 322, and the suspension rope 33 extends from the lower side of the shell 321.

[0032] In this structure, the torsion spring 324 is provided to provide a recovery elastic force for the rotating roller 322, and reduce the moving force of the clamping seat 35 and the upper shell 51. It is worth noting that the selection of the torsion spring 324 needs to ensure that when the telescopic cylinder 36 is fully recovered, the suspension rope 33 extends from under the positioning seat and reserves a certain length. When the telescopic cylinder 36 contacts and moves down the blocking seat 341, the elastic recovery roller 32 is in an upward pulling state to ensure that the suspension rope 33 is tightened.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
