[0042] Reference Figures 1-5 A positioning device for producing a grid pattern includes a sensor mounting frame, a positioning and moving mechanism, an upper mold for the grid pattern 4, two upper sensing mechanisms, a lower mold for the grid pattern 3, and four clamping and positioning sensing mechanisms.

[0043] The positioning and moving mechanism is movably installed at the upper middle of the induction mounting frame. The positioning and moving mechanism can be driven to lift and lower at the upper middle of the induction mounting frame. The induction mounting frame includes a concave frame 1. Screw lugs 11 are fixed to the lower two sides of the concave frame 1. Screws can be installed in designated positions through the screw holes of the screw lugs 11. An upper infrared sensor 12 is fixed to the upper inner wall of the concave frame 1. The upper infrared sensor 12 can emit infrared rays to sense the position. Below the upper infrared sensor 12, a lower infrared sensor 13 is fixed to the concave frame 1. The lower infrared sensor 13 can emit infrared rays to sense the position. The upper infrared sensor 12 and the lower infrared sensor 13 are electrically connected to the control box through connecting wires. The upper infrared sensor 12 and the lower infrared sensor 13 can transmit the infrared sensing data to the control box. Then, the personnel can directly view the internal data information and effectively compare the data difference to identify whether there is a positioning deviation. This is more accurate than visual inspection.

[0044] The upper infrared sensor 12 and the lower infrared sensor 13 are located directly behind the upper mold 4 and the lower mold 3 of the zigzag grid, respectively. They can effectively perform infrared distance sensing and thus identify whether there is a positioning deviation by measuring the distance difference.

[0045] Reference Figures 1-4 The die 4 on the grid pattern is mounted on the lower end of the positioning and moving mechanism by screws. The positioning and moving mechanism can change the position of the die 4 on the grid pattern during lifting and lowering. The positioning and moving mechanism includes a first hydraulic telescopic cylinder 6. A screw mounting plate 62 is fixedly connected to the periphery of the first hydraulic telescopic cylinder 6. The first hydraulic telescopic cylinder 6 can be mounted on the concave frame 1 by screws on the screw mounting plate 62. A telescopic cylinder mounting plate 61 is fixedly connected to the telescopic rod end of the first hydraulic telescopic cylinder 6. The position of the telescopic cylinder mounting plate 61 can be changed when the telescopic rod of the first hydraulic telescopic cylinder 6 extends or retracts. Two pulling end rods 53 are symmetrically fixed to the outer wall of the cylinder body of the first hydraulic telescopic cylinder 6. The pulling end rods 53 can be stably placed on the first hydraulic telescopic cylinder 6. The other end of the end rod 53 is fixedly connected to a positioning collar 52. Pulling the end rod 53 can move the positioning collar 52 to position. The positioning collar 52 is fitted with a positioning shaft 5. The positioning collar 52 allows the positioning shaft 5 to be positioned and moved through the internal area. The lower end of the positioning shaft 5 is fixedly connected to a shaft screw disc 51. The positioning shaft 5 can be installed correspondingly through the shaft screw disc 51. The shaft screw disc 51 and the telescopic cylinder mounting disc 61 are installed on the zigzag grid mold 4 with screws. When the telescopic cylinder mounting disc 61 is raised and lowered, it can drive the zigzag grid mold 4 to be raised and lowered. When the zigzag grid mold 4 is raised and lowered, it can drive the shaft screw disc 51 to be raised and lowered. When the shaft screw disc 51 is raised and lowered, it can drive the positioning shaft 5 to be raised and lowered.

[0046] The positioning shaft 5 is sleeved in the inner sleeve hole at the upper end of the concave frame 1, which can effectively position and move the machine.

[0047] Reference Figure 1 , Figure 4 and Figure 5 Four upper sensing mechanisms are symmetrically installed at the four corners of the upper end of the zigzag grid mold 4. They can perform infrared sensing from both sides. The upper sensing mechanism includes a connecting end plate 7. The inner side of the connecting end plate 7 is equipped with assembly screws 72. The connecting end plate 7 can be installed and placed accordingly through the assembly screws 72 to meet the installation needs of different sizes of zigzag grid molds 4. The connecting end plate 7 is installed and connected to the zigzag grid mold 4 through the assembly screws 72, and can be installed and placed stably. One end of the connecting end plate 7 is fixedly connected to the mounting end block 73. After the connecting end plate 7 is fixedly connected, it can drive the mounting end block 73 to be placed stably. The lower inner side of the mounting end block 73 is fixedly connected to an infrared emission sensor 71. The infrared emission sensor 71 can stably emit infrared light on the mounting end block 73 to determine the positioning position.

[0048] The lower mold 3 of the zigzag grid is installed on the inner side of the lower end of the induction mounting frame with screws, which can be installed stably and is located directly below the upper mold 4 of the zigzag grid, which facilitates the corresponding closure for the processing and preparation of the zigzag grid.

[0049] Four clamping and positioning sensing mechanisms are symmetrically installed on the outside of the die 4 on the grid pattern, enabling effective clamping and placement. These mechanisms are fixed to the sensing mounting frame for stable clamping. Each clamping and positioning mechanism includes a positioning sleeve 2, the lower end of which is fixed to the concave frame 1 for stable placement. A metal screw 24 is threaded onto the inner side of the positioning sleeve 2. When the metal screw 24 rotates forward, it moves within the threaded section of the positioning sleeve 2. An I-shaped rotating post 23 is fixed to the inner end of the metal screw 24. The screw 24 can drive the I-shaped rotating column 23 to rotate during rotation. The I-shaped rotating column 23 is rotatably mounted on the periphery of the rotating column 23. The I-shaped rotating column 23 can rotate in the rotating column 22. When the metal screw 24 moves inward, it can drive the rotating column 22 to move inward. An infrared receiving sensor 21 is fixedly connected to the upper end of the rotating column 22. The rotating column 22 can abut against the outside of the mold 4 on the grid and change the position of the infrared receiving sensor 21. The bottom ends of the rotating column 22 and the positioning sleeve 2 are aligned, which facilitates installation and placement.

[0050] The infrared receiving sensor 21 and the infrared emitting sensor 71 are combined to form a through-beam sensor, which can effectively sense through beams. When the beams disappear, a false touch will occur on the surface. The infrared receiving sensor 21 and the infrared emitting sensor 71 are electrically connected to the control box through a connecting cable, and the data can be effectively transmitted to the control box for easy viewing by personnel.

[0051] Working principle: During use, the positioning and moving mechanism is movably installed at the upper middle of the induction mounting frame. The positioning and moving mechanism can be driven to rise and fall at the upper middle of the induction mounting frame. The upper infrared sensor 12 and the lower infrared sensor 13 of the positioning and moving mechanism are located directly behind the upper mold 4 and the lower mold 3 of the zigzag grid, which can effectively perform infrared distance sensing, thereby identifying whether there is a positioning deviation by the distance difference.

[0052] The first hydraulic telescopic cylinder 6 of the positioning and moving mechanism can change the position of the telescopic cylinder mounting plate 61 when it extends or retracts. The shaft screw plate 51 and the telescopic cylinder mounting plate 61 are installed on the zigzag grid mold 4 by screws. When the telescopic cylinder mounting plate 61 rises or falls, it can drive the zigzag grid mold 4 to rise or fall. When the zigzag grid mold 4 rises or falls, it can drive the shaft screw plate 51 to rise or fall. When the shaft screw plate 51 rises or falls, it can drive the positioning shaft 5 to rise or fall. The connecting end plate 7 of the upper sensing mechanism is installed and connected to the zigzag grid mold 4 by assembly screws 72, which can be stably installed and placed. After the connecting end plate 7 is fixed, it can drive the mounting end block 73 to be stably placed. The infrared emitting sensor 71 can stably emit infrared rays on the mounting end block 73 to determine the positioning position. When the metal screw 24 of the clamping positioning sensing mechanism moves inward, it can drive the movable end block 22 to move inward. The upper end of the movable end block 22 is fixedly connected to the infrared receiving sensor 21. The movable end block 22 can abut against the outside of the zigzag grid mold 4 and change the position of the infrared receiving sensor 21. The infrared receiving sensor 21 and the infrared emitting sensor 71 are combined to form a through-beam sensor, which can effectively sense through beams. When the beams disappear, a false touch will occur on the surface. The infrared receiving sensor 21 and the infrared emitting sensor 71 are electrically connected to the control box through a connecting cable, and the data can be effectively transmitted to the control box for easy viewing by personnel.

[0053] The wiring diagrams of the first hydraulic telescopic cylinder 6, upper infrared sensor 12, lower infrared sensor 13, infrared receiving sensor 21, and infrared emitting sensor 71 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the first hydraulic telescopic cylinder 6, upper infrared sensor 12, lower infrared sensor 13, infrared receiving sensor 21, and infrared emitting sensor 71 will not be explained in detail.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
