[0022] In the current printed circuit board production process, as one of the key materials, the management of the transfer, temporary storage, and transportation of the film is crucial. However, traditional methods mostly rely on manual handling and random stacking, resulting in the film being placed in a messy manner and lacking effective protection during transportation, which is extremely likely to cause the film to be damaged and scrapped. This not only increases the production cost but also seriously reduces the work efficiency and deteriorates the working environment. Therefore, it is particularly important to develop a device that can standardize the film transfer, reduce damage, and improve work efficiency.

[0023] For this reason, referring to Figure 1 , the present utility model proposes a printed circuit board film transfer device, which includes a rectangular frame body 100 formed by a plurality of cross bars 110 and a plurality of vertical bars 120. The rectangular frame body 100 is used to accommodate the film. Among them, three adjacent sides of the rectangular frame body 100 have three vertical bars 120, and one side has two vertical bars 120 to form an opening 102 for the film to pass through. A plurality of cross bars 110 are arranged vertically and horizontally in the middle of the vertical bars 120 to form two cavities 101 separated up and down. Rollers are provided at the four corners of the bottom of the rectangular frame body 100.

[0024] Specifically, the rectangular frame body 100 is formed by connecting a plurality of cross bars 110 and a plurality of vertical bars 120 to form a stable rectangular structure. Each of the three adjacent sides of the rectangular frame body 100 is provided with three vertical bars 120 to provide sufficient support strength; while one side is specially designed with two vertical bars 120, with an appropriate gap left between them to form an opening 102 for the film to pass through, facilitating the loading and unloading of the film. Further, inside the rectangular frame body 100, a plurality of cross bars 110 and vertical bars 120 are arranged vertically and horizontally to form two independent cavities 101 separated up and down in the middle. Such a design not only effectively utilizes the space but also can store films of different specifications or batches according to actual needs to avoid confusion. Further, rollers are installed at the four corners of the bottom of the rectangular frame body 100, enabling the entire device to move easily, greatly reducing the labor intensity of manual handling and improving the transfer efficiency. At the same time, the design of the rollers also facilitates rapid shuttling between production lines to meet the requirements of different working environments.

[0025] In a specific embodiment, first, according to the size and weight of the film, appropriate materials for the cross bar 110 and the vertical bar 120 are selected, preferably stainless steel in the present utility model. And they are cut and processed according to requirements. Then, the cross bar 110 and the vertical bar 120 are assembled into a rectangular frame 100 by welding or bolt connection to ensure a stable and reliable structure. On one side of the rectangular frame 100, an opening 102 for the film to pass through is reserved, and two vertical bars 120 are installed as the frame of the opening 102. Next, in the middle of the rectangular frame 100, the cross bar 110 and the vertical bar 120 are welded or fixed vertically and horizontally according to the preset spacing and layout to form two cavities 101 separated up and down. The size and number of the cavities 101 can be adjusted according to actual needs to meet the storage requirements of films with different specifications and quantities. Rollers are installed at the four bottom corners of the rectangular frame 100, and it is ensured that the rollers rotate flexibly and have a strong load-bearing capacity. After completing the above steps, the film can be loaded into the rectangular frame 100 through the opening 102 and easily moved to the designated position by using the rollers for the next operation. In some embodiments, referring to Figure 1 , the cross bar 110 includes 18 pieces, the vertical bar 120 includes 7 pieces, and they are connected by welding. All weld points are polished. The entire rectangular frame 100 has a height of 1500 mm, the cavity 101 is partitioned at a height of 730 mm, the total length is 810 mm, and the width is 660 mm.

[0026] It can be understood that through the cavities 101 separated in the rectangular frame 100, the standardized stacking and placement of the films are realized, avoiding the problem of messy placement of films in the traditional way and improving the cleanliness of the production site.

[0027] Referring to Figure 1 , a pressing plate 200 is arranged inside the cavity 101. The pressing plate 200 is fixed to the top or a specific position of the rectangular frame 100 by detachable means such as bolts or buckles, so that its position can be easily adjusted to abut against the upper surface of the uppermost film. It is ensured that the films will not rub against each other or stack unstably due to shaking during transportation, further reducing the risk of film damage.

[0028] Furthermore, a collar 210 is connected to the pressing plate 200. The collar 210 is designed to match the sliding groove on the vertical bar 120, so that the collar 210 can slide up and down along the vertical bar 120. The sliding groove is located on the side away from the opening 102 to ensure that the collar 210 and the pressing plate 200 will not interfere with the normal loading and unloading of the films when moving. By adjusting the position of the collar 210, the pressing degree of the pressing plate 200 on the films can be conveniently controlled to adapt to films with different thicknesses and quantities.

[0029] In order to limit the lateral movement of the film in the cavity 101, a limiting convex strip 300 is provided on different vertical rods 120 on the same side. The limiting convex strip 300 and the collar 210 are respectively located at different positions of the vertical rod 120, but both face the inside of the cavity 101. When the film is placed in the cavity 101, its end will naturally abut against the limiting convex strip 300, thereby limiting the horizontal movement of the film. Such a design not only enhances the stability of the film during transportation, but also avoids deformation of the film due to mutual squeezing.

[0030] Furthermore, the limiting convex strip 300 is directly connected to the side wall of the vertical rod 120 facing the opening 102 to ensure its stability. At the same time, we ensure that the thickness of the limiting convex strip 300 is not less than the thickness of the collar 210 to prevent the collar 210 from interfering with the limiting convex strip 300 during the sliding process. This ensures both the compactness of the structure and the smooth coordination between the various components.

[0031] In order to reduce the friction and damage to the edge of the film, the limiting convex strip 300 is preferably made of a soft elastic material, such as rubber or silica gel. This material has good elasticity and wear resistance, and can effectively limit the movement of the film while protecting the edge of the film from damage.

[0032] In order to facilitate the operator to carry and move the entire transfer device, a handle 400 is provided in the middle of the rectangular frame 100. The handle 400 is fixed to one of the cross bars 110 by welding or bolting, and is located on one side of the opening 102.

[0033] In order to improve the flexibility and stability of the transfer device, two universal wheels 30 and two fixed wheels 140 are provided. The universal wheels 30 are located on the side close to the handle 400, so that the operator can easily control the device when changing the direction; while the fixed wheels 140 are located on the side away from the handle 400, so as to provide the transfer device with stable straight-line driving ability. Such a combined design ensures both the flexibility of the transfer device and its stability during transportation.

[0034] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
