Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example A conveying device for processing elevator door panels includes support columns 1, which are arranged in pairs facing each other. The two opposing support columns 1 form a single-sided support. A drive motor 2 is fixedly connected to the support column 1 of one set of single-sided supports. The output shaft of the drive motor 2 passes through the support column 1 and is fixedly connected to a rotating shaft. A sleeve 3 is fixedly connected to the rotating shaft. Drive teeth 4 are symmetrically fixedly connected to the sleeve 3. A support shaft is fixedly connected between the support columns 1 of the other set of single-sided supports. A sleeve 3 is rotatably connected to the support shaft. Drive teeth 4 are symmetrically fixedly connected to the sleeve 3. The drive teeth 4 on the two sets of single-sided supports are connected by a chain 5. The system utilizes four supporting columns 1 to form a support structure. The opposing supporting columns 1 form a single-sided support group. The group equipped with a drive motor 2 is the power group, and the group without a drive motor 2 is the driven group. The power group drives the driven group to rotate. The drive gear 4 on the power group and the drive gear 4 on the driven group are connected by a chain 5 to achieve power transmission. The chain 5 provides stable power output and sufficient power to move multiple fixed plate structures 6 and related structures.

[0020] Several fixed plate structures 6 are provided between the two chains 5. The fixed plate structures 6 are fixedly connected to the double-headed cylinders 7. The output shafts at both ends of the double-headed cylinders 7 are fixedly connected to the lifting mechanism 8. A rotating clamping mechanism 9 is provided on one side of the lifting mechanism 8. The working mode of the double-headed cylinder 7 is simultaneous inlet and outlet. By moving the double-headed cylinder 7 simultaneously, the elevator door panel can be clamped and lowered. The lifting mechanism 8 drives the rotating clamping mechanism 9 to clamp the center position of the side of the elevator door panel, which facilitates the rotating clamping mechanism 9 to rotate the elevator door panel.

[0021] The lifting mechanism 8 includes a connecting arm 81, with a telescopic cylinder 82 fixedly installed below the connecting arm 81. The output end of the telescopic cylinder 82 is fixedly connected to an extension arm 83, and a rotating motor is embedded inside the extension arm 83. The telescopic cylinder 82 is a single-output telescopic cylinder. The telescopic cylinder 82 drives the extension arm 83 to extend and retract, clamping the center position of the side of the elevator door panel. During the loading of the elevator door panel, the extension clamps the panel, eliminating the need for manual lifting of the elevator door panel for loading. During the unloading of the elevator door panel, the extension and retraction ensure the lowering height and avoid damage to the elevator door panel caused by unloading from an excessively high height.

[0022] The rotating clamping mechanism 9 includes rectangular clamping blocks 91. The surfaces of the rectangular clamping blocks 91 facing each other are provided with rubber layers 92. Threaded holes 93 are opened on the rubber layers 92. The output shaft of the rotating motor is fixedly connected to the rectangular clamping blocks 91. The torque of the rotating motor needs to meet the rotation requirements of the elevator door panel. The rubber layers 92 are used to squeeze the sides of the elevator door panel to increase friction and ensure the stability of the clamping. The clamping of the elevator door panel is achieved by the contraction of the double-headed cylinder 7.

[0023] The 93 threaded hole connects to the suction cup. The external suction cup is used to minimize the contact area with the sides when spraying elevator door panels, ensuring that more of the side areas can be sprayed.

[0024] Both sets of single-sided support columns 1 are equipped with positioning cameras 10. The positioning cameras 10 capture images of the entire moving range of the chain 5. By capturing images with the positioning cameras 10, the position and operation of each set of fixed plate structure 6 and related structures are located throughout the entire process. Data processing and positioning control functions are performed using the processing center in the control panel to improve the degree of automation. One of the support columns 1 is equipped with a control panel 11, and a safety protection structure 12 is provided between the support columns 1.

[0025] The safety protection structure 12 consists of two partitions, with a support column 1 fixedly connected to one side of each partition. A channel is provided between the partitions, and several reinforcing ribs are provided on the downward side of the partitions. The column can pass through the middle of the channel. In case of danger, such as when the chain 5 breaks, the downward trend of the elevator door is blocked by the obstruction between the partition and the horizontal plate, thus ensuring safety.

[0026] The fixed plate structure 6 includes a horizontal plate, on one side of which a vertical rod is fixedly mounted. The vertical rod is fixedly connected to a double-headed cylinder 7. By combining the fixed plate structure 6 with the safety protection structure 12, the safety performance is improved.

[0027] The telescopic cylinder 82 and the rotating motor move synchronously, which facilitates synchronous rotation and extension.

[0028] Working principle: As shown in the figure, during use, the elevator door panel to be processed enters from one side of the power unit. The positioning camera 10 is used for positioning. The telescopic cylinder 82 is activated to extend the extension arm 83 until the rectangular clamping block 91 can contact the center of the side of the elevator door panel. Then, the double-headed cylinder 7 is activated to retract towards the center, driving the rectangular clamping block 91 to clamp the elevator door panel, thus completing the loading. After loading, the processing equipment can be placed directly below this device according to the processing requirements. The rotating motor drives the rectangular clamping block 9 to rotate, thereby rotating the elevator door panel. Both sides of the elevator door panel can be processed. After the operation is completed, the telescopic cylinder 82 extends the extension arm 83 to minimize the distance between the elevator door panel and the unloading receiving rack. The rotating motor rotates and the double-headed cylinder 7 slowly extends to lower the elevator door panel.

[0029] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
