[0017] Please see Figure 1-6 A positioning and cutting mechanism for LCD display module processing includes a cutting box 1. Support feet 2 are connected to both sides of the bottom of the cutting box 1. Doors 4 are connected to both sides of the front end of the cutting box 1 via hinges 3. A base 5 is connected to the bottom of the interior of the cutting box 1. A worktable 6 is connected to the top of the base 5. A notch 7 is formed on the top of the worktable 6. A groove 22 is formed on the top of the worktable 6 to the left of the notch 7. Multiple positioning threaded holes 8 are formed at the bottom of the groove 22. A positioning block 9 is placed in the groove 22. Fastening bolts 11 pass through the positioning block 9 and are threadedly connected to the positioning threaded holes 8 at both ends of the positioning block 9. A limit plate 10 is connected to the top of the positioning block 9. The groove 22, positioning threaded holes 8, positioning block 9, and fastening bolts 11 are used to... The interaction between the two parts allows for left and right adjustment of the position of the limiting plate 10, thereby meeting the needs of different usage positions and enabling the cutting and processing of LCD display modules of different sizes, thus expanding the processing range. A telescopic cylinder 12 is installed at the upper right end of the worktable 6, and a clamping plate 13 is connected to the right end of the telescopic cylinder 12. Two guide rails 14 are symmetrically arranged at the top inside the cutting box 1, and a slider 16 is arranged between the two guide rails 14. A power cylinder 15 is connected to the front end of the slider 16, and a lifting cylinder 17 is connected to the bottom of the slider 16. A lifting block 18 is connected to the bottom of the lifting cylinder 17, and a support frame 19 is connected to the bottom of the lifting block 18. A cutting motor 20 is installed on the support frame 19, and a cutting blade 21 is installed on the output shaft of the cutting motor 20.

[0018] One side of the power cylinder 15 is connected to the top of the inner side of the cutting box 1.

[0019] The support frame 19 has an L-shaped structure.

[0020] The slider 16 can slide horizontally between the two guide rails 14.

[0021] The cutting blade 21 is located directly above the notch 7.

[0022] The number of support feet 2 is set to four, and the four support feet 2 are arranged in pairs facing each other about the bottom of the cutting box 1.

[0023] The number of hinges 3 is set to four, and the four hinges 3 are arranged in pairs opposite each other about the bottom of the cutting box 1.

[0024] The length of the limiting plate 10 is greater than the width of the groove 22.

[0025] The working principle and usage process of this utility model are as follows: Before cutting, the operator first needs to adjust the positioning reference according to the size of the LCD display module to be processed. The operator first loosens the fastening bolts 11 at both ends so that the positioning block 9 is no longer fixed in the groove 22. Then, according to the required size of the module, the entire assembly of positioning block 9 and limiting plate 10 is slid along the direction of groove 22. When the limiting plate 10 moves to the predetermined position, the fastening bolts 11 are tightened again so that its lower end is screwed into the corresponding positioning threaded hole 8, thereby firmly fixing the positioning block 9 on the worktable 6. At this time, the limiting plate 10 becomes a vertical and immovable reference surface. This design is an important innovation of this application. It breaks through the limitations of the traditional fixed positioning mechanism, so that a set of fixtures can adapt to the processing of products of various specifications, greatly expanding the processing range of the equipment and improving the versatility and utilization of the equipment. After the positioning settings are completed, the workpiece is clamped. The operator places the LCD display module on the worktable 6, with one side of the module pressed against the vertical surface of the fixed limiting plate 10. This ensures that all workpieces have a consistent and accurate positional reference each time they are clamped. The telescopic cylinder 12 is activated, and its piston rod extends, pushing the clamping plate 13 to the left. This presses the workpiece against the limiting plate 10 from the other side. Through the combined action of the limiting plate 10 and the clamping plate 13, the workpiece is firmly clamped on the worktable 6, preventing movement during the cutting process and ensuring cutting accuracy. After the workpiece is fixed, the cutting motor 20 starts, driving the cutting blade 21 on its output shaft to rotate at high speed. This is the direct power source for cutting. The lifting cylinder 17 is activated, pushing the lifting block 18, support frame 19, cutting motor 20 and cutting blade 21 to move downward as a whole until the cutting blade 21 descends to the predetermined cutting depth. The power cylinder 15, as the driving source for horizontal movement, pushes the slider 16 to move smoothly and precisely in a straight line along the two guide rails 14. The movement of the slider 16 drives the entire cutting head connected below it, including the lifting cylinder 17, lifting block 18, support frame 19, cutting motor 20 and cutting blade 21, to move horizontally together. The cutting blade 21, which is rotating at high speed, then slashes across the workpiece fixed on the worktable. Since there is a notch 7 directly below the workpiece, the cutting blade can pass through completely without cutting the worktable 6 body, which protects the blade and completes the complete separation and cutting of the workpiece. After the cutting blade 21 completes one stroke, the power cylinder 15 stops or reverses its movement, causing the cutting head to return to its initial position. The lifting cylinder 17 raises the cutting head, causing the cutting blade 21 to leave the workpiece area. The telescopic cylinder 12 retracts, and the clamping plate 13 releases the workpiece. The operator can then remove the LCD display module that has been cut and place the next workpiece to be processed, repeating the above process. Any content not described in detail in this instruction belongs to the prior art known to those skilled in the art.

[0026] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
