Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] An automatic positioning device for the end of a panel conveyor for panel assembly, such as... Figure 1-5As shown, it includes a positioning block 1, a positioning block support 2, a hydraulic cylinder 3, a hydraulic cylinder support 4, a first pin 5.1, a second pin 5.2, a third pin 5.3, a fourth pin 5.4, a spring 6, a sensing block 7, a photoelectric switch 8, a photoelectric switch support 9, a spring positioning rod mounting plate 10, and a spring positioning rod 11.

[0021] The positioning block support 2 and the hydraulic cylinder support 4 are fixed on the frame. The hydraulic cylinder support 4 is located behind the positioning block support 2. The positioning block 1 is hinged to the positioning block support 2 by the first pin 5.1. The hydraulic cylinder 3 is hinged to the hydraulic cylinder support 4 by the second pin 5.2. The piston rod end of the hydraulic cylinder 3 is hinged to the positioning block 1 by the third pin 5.3.

[0022] The sensing block 7 is hinged to the positioning block 1 via the fourth pin 5.4. The sensing block 7 is located on the outside of the positioning block 1. A spring positioning rod mounting plate 10 is fixed on the front end face of the positioning block 1. Spring positioning rods 11 are fixed on the spring positioning rod mounting plates 10 above and below the corresponding fourth pin 5.4. A spring 6 is installed on each spring positioning rod 11. A photoelectric switch support 9 is fixed on the outer side of the positioning block 1 above and behind the corresponding fourth pin 5.4. A photoelectric switch 8 is fixed on the photoelectric switch support 9.

[0023] The positioning block 1 includes a front section 1.1 and a rear section 1.2. The thickness of the front section 1.1 is less than the thickness of the rear section 1.2. The inner surface of the front section 1.1 is flush with the inner surface of the rear section 1.2. The rear section 1.2 is hinged to the positioning block support 2 by a first pin 5.1. The piston rod end of the hydraulic cylinder 3 is hinged to the rear section 1.2 by a third pin 5.3.

[0024] The sensing block 7 is hinged to the front section 1.1 of the positioning block via the fourth pin 5.4.

[0025] The photoelectric switch support 9 is fixed on the outer side of the front section 1.1 of the positioning block.

[0026] The spring positioning rod mounting plate 10 is fixed on the front end face of the front section 1.1 of the positioning block. Part of the spring positioning rod mounting plate 10 is located on the outside of the front section 1.1 of the positioning block, and the spring positioning rod 11 is fixed on the spring positioning rod mounting plate 10 located on the outside of the front section 1.1 of the positioning block.

[0027] The working principle and process of this utility model are as follows:

[0028] In actual use, at least two sets of the automatic positioning device for the end of the splicing plate conveying of this utility model need to be installed on the frame. Each set of automatic positioning device for the end of the splicing plate conveying is installed above the plate (i.e., steel plate) conveying device 20.

[0029] In this utility model, the positioning block 1 is hinged to the positioning block support 2 via the first pin 5.1, giving the positioning block 1 a fulcrum. The hydraulic cylinder 3 is hinged to the hydraulic cylinder support 4 via the second pin 5.2, giving the hydraulic cylinder 3 a fulcrum as well. The piston rod end of the hydraulic cylinder 3 is hinged to the positioning block 1 via the third pin 5.3, so that the lifting and lowering of the positioning block 1 can be controlled by extending and retracting the piston rod of the hydraulic cylinder 3.

[0030] During operation, the piston rod of the hydraulic cylinder 3 extends to its longest position, causing the positioning block 1 to descend to the predetermined position. When the plate 100 (i.e., the steel plate) touches the sensing block 7, it rotates around the fourth pin 5.4. After the photoelectric switch 8 senses the sensing block 7, it will cause the plate (i.e., the steel plate) conveying device 20 to stop conveying, ultimately positioning the plate 100 in the designated position and ensuring the straightness of the plate 100. After the positioning is completed, the piston rod of the hydraulic cylinder 3 retracts, and the sensing block 7 will also be bounced back to its original position by the spring 6, making it convenient for continued use next time.

[0031] In this utility model, the thickness of the front section 1.1 of the positioning block 1 is less than the thickness of the rear section 1.2 of the positioning block. The sensing block 7, the photoelectric switch support 9 and the spring positioning rod mounting plate 10 are all installed on the front section 1.1 of the positioning block. When the positioning block 1 is retracted (that is, the piston rod of the hydraulic cylinder 3 is retracted to the shortest state), interference with the frame can be avoided.

[0032] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
