[0020] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate exemplary embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention.

[0022] Figure 1 The figure shows a front view of a fixture for filling glue on a folding screen steel sheet provided by an embodiment of the present invention; Figure 3 The figure shows a front view of a fixture for filling glue on a folding screen steel sheet provided by an embodiment of the present invention. Figure 1 and Figure 3 As shown, the fixture for filling glue on folding screen steel sheets provided by the present invention comprises a fixed bottom plate 1, a steel sheet placement base 2, a plurality of first support columns 3, a top glue block 4, and a top glue power structure. Among them, the fixed bottom plate 1 is used for the fixed placement of the entire fixture, and is fixedly connected to the steel sheet placement base 2 through a plurality of first support columns 3; the lower ends of the plurality of first support columns 3 are fixed to the upper surface of the fixed bottom plate 1, and the upper ends of the plurality of first support columns 3 are fixed to the lower surface of the steel sheet placement base 2. Figure 1 and Figure 3In the embodiment shown, the fixture for filling glue on the folding screen steel sheet provided by the present invention includes four first support columns. It will be understood by those skilled in the art that other numbers of first support columns may also be included, as long as good stability can be provided to prevent the steel sheet placement base from being displaced or tilted during the glue filling process, thereby ensuring the uniformity and effect of the glue filling. The present invention is not limited to this; the upper surface of the steel sheet placement base 2 is used to place the steel sheet to be filled with glue, and a glue storage tank 21 for storing glue is provided, wherein the position of the glue storage tank 21 is determined according to the position where glue needs to be filled on the steel sheet to be filled. The design ensures that after the steel sheet to be filled with glue is placed on the steel sheet placing base 2, the glue storage tank 21 corresponds to the position where glue needs to be filled on the steel sheet to be filled, thereby ensuring that the glue will not overflow to other areas during use; the top glue block 4 is movably arranged at the bottom of the glue storage tank 21, wherein the upper surface of the top glue block 4 is the bottom of the glue storage tank 21, and the shape of the top glue block 4 is adapted to the glue storage tank 4 to ensure that the top glue block 4 can move up and down along the glue storage tank 21 and ensure that the glue in the glue storage tank will not overflow during the movement; the top glue power structure is arranged below the top glue block 4 and can push the top glue block 4 to move up and down along the glue storage tank 21.

[0023] Furthermore, in one embodiment of the present invention, the top glue power structure includes a cylinder fixing base plate 5, a plurality of second support columns 6, a cylinder 7, a floating joint 8 and a speed regulating valve 13. Among them, the cylinder fixing base plate 5 is used to fix the cylinder 7, which is fixedly connected to the steel sheet placement base 2 through a plurality of second support columns 6; the lower ends of the plurality of second support columns 6 are fixed to the upper surface of the cylinder fixing base plate 5, and the upper ends of the plurality of second support columns 6 are fixed to the lower surface of the steel sheet placement base 2. Figure 1 and Figure 3 In the embodiment shown, the fixture for filling glue on the folding screen steel sheet provided by the present invention includes four second support columns. It will be understood by those skilled in the art that other numbers of second support columns may also be included, and the present invention is not limited to this; the cylinder 7 is used to provide a power source for the top glue block 4 to push the top glue block 4 to move up and down along the glue storage tank, and it is installed on the lower surface of the cylinder fixed base plate 5; the floating joint 8 is floatingly connected between the cylinder 7 and the top glue block 4, and its lower end is connected to the cylinder 7 installed on the lower surface of the cylinder fixed base plate 5 through the connection hole opened on the upper surface of the cylinder fixed base plate 5, and the upper end is connected to the lower surface of the top glue block 4. When the cylinder 7 moves, it pushes the floating joint 8 to float up and down, thereby driving the top glue block 4 to move up and down; the speed regulating valve 13 is installed on the cylinder 7 for controlling the speed of the cylinder 7 movement. It is connected to the external pneumatic valve through the air pipe, and controls the speed of the cylinder movement under the control of the pneumatic valve. The clamp of the utility model adopts an air cylinder to control the movement of the glue groove, which can maintain the position continuously after filling with glue. After the glue solidifies, the air cylinder is controlled to retract for degumming, avoiding the deformation caused by unsolidified glue.

[0024] In the present invention, by using a plurality of second support columns 6 to fix the cylinder fixing base plate 5 to the steel sheet placement base 2, the load applied to the cylinder fixing base plate can be effectively dispersed, local stress concentration is reduced, and thus the stability and durability of the structure are improved; the lower end of the second support column 6 is fixed to the upper surface of the cylinder fixing base plate 5, while the upper end is fixed to the lower surface of the steel sheet placement base 2. This fixing method can ensure the sturdiness of the entire device during operation and reduce vibration and displacement. The speed control valve 13 installed on the cylinder 7 is used to accurately control the movement speed of the cylinder. By adjusting the opening of the speed control valve, the rising and falling speeds of the top glue block 4 can be flexibly controlled, thereby achieving accurate glue filling, which is particularly important for the glue filling process that requires high precision and consistency. The automatic movement of the cylinder 7 and the control system of the speed control valve 13 simplify the operating procedures and make the glue filling process more automated. The operator only needs to set the parameters, and the fixture can automatically complete the glue filling, reducing manual intervention and operating difficulty; the automated glue filling process can significantly reduce the errors caused by human operation, ensure the consistency of the glue filling quality of each workpiece, and improve production efficiency and product quality.

[0025] Furthermore, in an embodiment of the present invention, as Figure 3 As shown, the fixture for filling glue on folding screen steel sheets of the present invention also includes a plurality of limit adjustment blocks 11, each limit adjustment block 11 fixes the two ends of the lower surface of the top glue block 4. When in use, the position of the top glue block is adjusted by the limit adjustment block according to the required amount of glue filling. After adjustment by the limit adjustment block, its position of upward and downward movement can be fixed, so that the amount of glue filling each time remains constant, avoiding waste of raw materials.

[0026] In the present invention, each limit adjustment block 11 fixes the two ends of the lower surface of the top glue block 4. By adjusting the position of these limit adjustment blocks, the upper and lower movable range of the top glue block 4 during the glue filling process can be accurately controlled. This precise control can ensure that the amount of glue filled each time remains consistent and meets the standard requirements of different production needs. By accurately controlling the movable range of the top glue block, the waste of raw materials caused by inaccurate glue filling amount can be effectively avoided, reducing production costs and reducing the impact on the environment. After adjusting the limit adjustment block, the upper and lower movable positions of the top glue block can be fixed so that it remains constant during the glue filling process. This fixation ensures the consistency of each glue filling, thereby improving the consistency and quality of the product. The stable glue filling amount reduces production problems caused by variations in the glue filling amount, such as uneven glue, unstable product quality, etc., thereby improving production efficiency and product qualification rate. In addition, the design of the limit adjustment block enables operators to quickly and conveniently adjust the glue filling amount according to actual needs. This adjustment mechanism simplifies the operating process and improves the flexibility of the production line. Once the desired fill volume is reached, the limit adjuster maintains its position, reducing the need for frequent adjustments, saving operator time and labor costs.

[0027] Furthermore, in an embodiment of the present invention, as Figure 3 As shown, the fixture for filling glue on folding screen steel sheets of the present invention also includes a plurality of positioning pins 12, which are detachably mounted on the upper surface of the steel plate placement base. When in use, the steel sheet to be filled with glue is placed on the steel plate placement base, and then the four sides are positioned by inserting the positioning pins 12 to ensure that the steel sheet to be filled with glue does not move during the filling process. This clamping and positioning method is simple and quick.

[0028] In the present invention, by inserting positioning pins on the steel plate placement base, the position of the steel sheet can be stabilized to prevent movement or tilting during the glue filling process, thereby ensuring the accuracy and uniformity of the glue filling. Stable positioning reduces production problems caused by inaccurate positioning of the steel sheet and improves the reliability of the overall production process. The detachable design of the positioning pins allows operators to quickly place and fix the steel sheet, saving time on adjustment and clamping. In addition, the operating steps are simple, reducing dependence on complex fixing devices and improving production efficiency. The use of positioning pins provides the fixture with greater stability and ease of operation, while increasing its adaptability in different production environments.

Figure 2 As shown, the steel sheet placement base 2 is also provided with a glue drain trough 22, located at one end of the glue storage tank 21. Excess glue after application is discharged through the drain trough. Providing the drain trough 22 on the steel sheet placement base 2 allows excess glue to flow out quickly during the glue filling process, preventing glue accumulation or overflow and ensuring accurate glue filling each time. The drain trough effectively recycles excess glue, reducing material waste and production costs. Effectively draining excess glue avoids production problems caused by excessive glue, reducing equipment downtime and the need for adjustments.

Figure 4As shown, the top glue power structure also includes a plurality of guide structures, each guide structure includes a guide shaft 9 and a linear bearing 10, the guide shaft 9 is installed between the lower surface of the cylinder fixed base 5 and the first position of the upper surface of the steel sheet placement base 2, and the linear bearing 10 is installed at the second position of the lower surface of the steel sheet placement base 2, and the first position corresponds to the second position. When designing the top glue power structure, the configuration of the guide structure is crucial to ensuring the stability and accuracy of the system. By installing the guide shaft 9 at the first position between the lower surface of the cylinder fixed base 5 and the upper surface of the steel sheet placement base 2, it can be ensured that the steel sheet placement base remains stable during movement. By installing the linear bearing 10 at the second position of the lower surface of the steel sheet placement base 2, corresponding to the guide shaft 9, a smooth guide movement can be provided to reduce friction. The guide shaft and the linear bearing are used in combination to prevent the steel sheet placement base 2 from offsetting during movement, ensure the accuracy of the position, and make the top glue action more precise.
