Description

Technical Field

[0001] The utility model relates to a transfer device, in particular to a transfer device suitable for transporting OLED protective film sheets. Background Art

[0002] The OLED protective film can effectively prevent the OLED screen from being scratched and worn, extend its service life, and also improve the wear resistance and anti-fingerprint ability of the OLED screen, keeping the screen clean. During the production process of the OLED protective film, it is necessary to cut the continuous strip-shaped OLED protective film into sheets of a certain specification. These sheets are stacked on top of each other and transported to the inner and outer packaging workstations in a fixed stacking quantity.

[0003] There is no automated production line between the existing protective film cutting and stacking equipment and the inner and outer packaging equipment to realize the transfer of sheets, and the cost of such an automated production line is relatively high. Currently, OLED protective film manufacturers often use flat transfer carts (turnover carts) to transfer the sheets. However, manual handling cannot be avoided during the transfer process. When the stacked sheets come into contact with the hands, it is very easy to cause sliding or wrinkling at the contact parts, which will not only affect the flatness of the sheets but also the neatness of the sheet stacking, thereby affecting the subsequent inner and outer packaging effects and resulting in a decrease in the product yield. Summary of the Invention

[0004] The utility model provides a transfer device suitable for transporting OLED protective film sheets, which solves the problem in the prior art that manual handling is required during the transfer of OLED protective film sheets, resulting in a decrease in the subsequent product yield.

[0005] The above technical problems of the present utility model are mainly solved by the following technical solutions: A transfer device suitable for transporting OLED protective film sheets, including a turnover rack and universal rollers provided at the bottom thereof, characterized in that: a horizontal bearing platform is provided on the upper side of the turnover rack, and a number of universal ball modules arranged in a matrix are provided on the horizontal bearing platform. The matrix is divided into a number of horizontal arrays and a number of vertical arrays. The universal ball module is composed of a ball seat and balls fixed on the horizontal bearing platform. A longitudinal slide rail distributed horizontally in the longitudinal direction is further provided on the turnover rack. A first sliding seat is slidably fitted on the longitudinal slide rail. An installation frame horizontally distributed in the transverse direction and extending above the horizontal bearing platform is fixed on the first sliding seat. A horizontally arranged transverse baffle is fixed on the installation frame. The bottom of the transverse baffle is lower than the highest point of the balls. A number of first avoidance grooves for avoiding the balls are opened on the transverse baffle. A transverse slide rail distributed horizontally in the transverse direction is provided on the installation frame. A second sliding seat is slidably fitted on the transverse slide rail. A longitudinally arranged longitudinal baffle is fixed on the second sliding seat. The bottom of the longitudinal baffle is lower than the highest point of the balls. A number of second avoidance grooves for avoiding the balls are opened on the longitudinal baffle. A magnetic stop block is further provided on the horizontal bearing platform. A magnetic switch is provided on the magnetic stop block. The contour of the magnetic stop block is "L" shaped.

[0006] The utility model uses a number of evenly distributed universal ball modules to form a supporting surface for supporting a protective film sheet. The protective film sheet can freely slide on the supporting surface without mechanical friction marks such as scratches on the surface of the protective film. Therefore, the utility model is docked at the discharging end of a cutting and stacking device, and the cut and stacked plates can be directly pushed onto the supporting surface. The pushing action can be completed manually or mechanically, and the pushing part is located on the side of the plate, which will not cause the problem of plate wrinkling. Similarly, when the utility model is docked at the feeding end of an internal and external packaging device, the plates can be pushed and transferred away. To facilitate loading and unloading, the height of the turnover rack of the utility model matches the height of the loading and unloading stations, so that the supporting surface is flush with the height of the loading and unloading stations. To prevent the plates from shifting or stacking unevenly due to jitter during the transfer process, the utility model positions the sheet material through a transverse baffle, a longitudinal baffle, and a magnetic stop block. The specific operation method is as follows: First, the positions of the transverse baffle and the longitudinal baffle are positioned by sliding and adjusting the positions of the first sliding seat and the second sliding seat. To ensure that all stacked plates can be positioned, the bottom of the baffle is set lower than the supporting surface, and at the same time, an avoidance groove is set to avoid the universal ball module. Then, the magnetic stop block is removed, and the stacked plates are pushed until they are in contact with both the transverse baffle and the longitudinal baffle. Finally, the magnetic stop block is placed at the other end of the plate, and by turning on the magnetic switch, the magnetic stop block is attracted and fixed on the horizontal carrier table. At this time, the stacked plates are positioned. When discharging, only the magnetic stop block needs to be removed, and the plate can be horizontally pushed for discharging.

[0007] Further, the longitudinal baffle is provided with a connecting piece fixedly connected to the second sliding seat. The connecting piece is provided with a slot distributed longitudinally, and at least two fastening bolts screwed to the second sliding seat are arranged in the slot. By adjusting the fastening bolts, the relative fixation or relative movement between the connecting piece and the second sliding seat can be achieved. Since the position adjustment of the first sliding seat will affect the relative position between the second avoidance groove and the universal ball module, if the adjusted position causes interference between the longitudinal baffle and the universal ball module, the interference can be avoided by adjusting the position of the connecting piece.

[0008] Further, locking bolts are screwed on both the first sliding seat and the second sliding seat, and the locking bolts can be screwed tightly to abut against the corresponding slide rails for fixation. By rotating and adjusting the relative positions of the locking bolts and the corresponding slide rails, the fixation or release of the two sliding seats can be achieved.

[0009] Therefore, the utility model has the following characteristics compared with the prior art: 1. The utility model is parked at the discharging end of the cutting and stacking equipment, and the cut and stacked plates can be directly pushed onto the supporting surface. The pushing action can be completed manually or mechanically. The pushing part is located on the side of the plate, which will not cause the problem of plate wrinkling; 2. The utility model positions the sheet material through the transverse baffle, longitudinal baffle and magnetic block to prevent the plate from shifting or being stacked unevenly due to the jitter generated during the transfer process.

[0016] Embodiment 1: See Figure 1 , Figure 3 and Figure 4A transfer device suitable for transporting OLED protective film sheets includes a turnover frame 100 and four universal rollers 110 arranged at the bottom thereof. A horizontal bearing platform 200 is arranged on the upper side of the turnover frame. 136 universal ball modules 300 are arranged in a matrix. The matrix is ​​divided into 17 rows of horizontal arrays and 8 rows of vertical arrays. The universal ball module is composed of a ball seat and a ball fixed on the horizontal bearing platform. The turnover frame is also provided with a longitudinal slide rail 120 distributed in the horizontal longitudinal direction. Two longitudinal slide rails are provided and are distributed on both sides of the horizontal bearing platform. A first sliding seat 130 is slidably matched on each of the two longitudinal slide rails. A horizontally distributed and spanning to the horizontal is fixed between the two first sliding seats. The mounting frame 140 above the bearing platform is fixed with two to three vertically arranged transverse baffles 150, the bottom of which is lower than the highest point of the ball, and the transverse baffle is provided with a plurality of first avoidance grooves 151 for avoiding the ball, and the mounting frame is provided with two transverse slide rails 160 distributed horizontally and transversely, and the transverse slide rail is slidably matched with a second sliding seat 170, and the second sliding seat is fixed with a longitudinal baffle 180 arranged vertically in the longitudinal direction, the bottom of which is lower than the highest point of the ball, and the longitudinal baffle is provided with a plurality of second avoidance grooves 181 for avoiding the ball, and the horizontal bearing platform is also provided with a magnetic block 400, and the magnetic block is provided with a magnetic switch 410, and the outline of the magnetic block is "L" shaped.

[0017] See Figure 2 , the longitudinal baffle is provided with a connecting piece 190 fixedly connected to the second sliding seat, and the connecting piece is provided with a slot 191 distributed along the longitudinal direction, and two fastening bolts 192 screwed to the second sliding seat are provided in the slot. By adjusting the fastening bolts, the connecting piece and the second sliding seat can be relatively fixed or relatively movable. Since the position adjustment of the first sliding seat will affect the relative position of the second avoidance groove and the universal ball module, if the adjusted position causes interference between the longitudinal baffle and the universal ball module, the interference can be avoided by adjusting the position of the connecting piece.

[0018] See Figure 4 , the first sliding seat and the second sliding seat are both screwed with a locking bolt 10, which can be tightened to abut against the corresponding slide rail and fixed. By rotating and adjusting the relative position of the locking bolt and the corresponding slide rail, the two sliding seats can be fixed or released.

[0019] In this embodiment, a supporting surface for supporting the protective film sheet is formed by a number of uniformly distributed universal ball modules. The protective film sheet can slide freely on this supporting surface without leaving mechanical friction marks such as scratches on the surface of the protective film. Therefore, when this embodiment is docked at the discharging end of the cutting and stacking equipment, the cut and stacked plates can be directly pushed onto the supporting surface. The pushing action can be completed manually or mechanically. The pushing part is located on the side of the plate, which will not cause the problem of the plate wrinkling. Similarly, when this embodiment is docked at the loading end of the inner and outer packaging equipment, the plates can be pushed and transferred away. To facilitate loading and unloading, the height of the turnover rack in this embodiment is matched with the height of the loading and unloading stations, so that the supporting surface is flush with the height of the loading and unloading stations. To prevent the plates from shifting or being stacked unevenly due to the jitter generated during the transfer process, this embodiment positions the sheet material through a transverse baffle, a longitudinal baffle, and a magnetic stop block. The specific operation method is as follows: First, the positions of the transverse baffle and the longitudinal baffle are positioned by sliding and adjusting the positions of the first sliding seat and the second sliding seat. After the position adjustment is completed, the locking bolts are tightened to fix the sliding seat. To ensure that all stacked plates can be positioned, the bottom of the baffle is set lower than the supporting surface, and at the same time, an avoidance groove is set to avoid the universal ball module. Then, the magnetic stop block is removed, and the stacked plates are pushed until they are in contact with both the transverse baffle and the longitudinal baffle. Finally, the magnetic stop block is placed at the other end of the plate, and by turning on the magnetic switch, the magnetic stop block is attracted and fixed on the horizontal carrier. At this time, the stacked plates are positioned. When discharging in this embodiment, only the magnetic stop block needs to be removed, and then the plate can be horizontally pushed for discharging.

[0020] It will be obvious to those skilled in the art that the present utility model can be changed in various ways. Such changes are not considered to depart from the scope of the present utility model. All such modifications obvious to those skilled in the art will be included within the scope of the present claims.
