[0041] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] In the related art, for the collection of waste film after the protective film is torn off, a discharge bin and a collection box that are connected to each other are used. After the waste film is thrown into the discharge bin, the protective film in the discharge bin will be transferred from the discharge bin to the collection box to realize the collection of the waste film. However, in the early stage of attaching the protective film, in order to ensure the attachment effect of the protective film to the display screen, glue is usually set on the attachment surface of the protective film, and the protective film is bonded and fixed to the display screen by glue. This results in the torn waste film also being provided with glue, and the waste film thrown into the discharge bin will be easily bonded and fixed to the inner wall of the discharge bin under the action of glue, which will lead to difficulties in discharging the waste film. Moreover, when a large amount of waste film accumulates in the discharge bin, it will also cause discharge blockage, affecting the normal discharge and collection of the waste film.

[0043] In order to solve the above problems, Figure 1 to Figure 4 As shown, this embodiment provides a waste film discharge collection device 100. The waste film discharge collection device 100 includes a discharge bin 110, a collection box 120, and a blowing mechanism, wherein a receiving chamber for collecting waste films is provided in the collection box 120, a discharge chamber 111 is provided in the discharge bin 110, and a feed inlet 112 and a discharge outlet 113 are provided on the discharge bin 110, which are respectively communicated with the discharge chamber 111, and the discharge outlet 113 is communicated with the receiving chamber in the collection box 120, and a blowing port 114 is provided on the outer wall of the discharge bin 110, which is communicated with the discharge chamber 111, and the blowing port 114 extends from the outside of the discharge bin 110 toward the direction close to the discharge chamber 111 and is inclined toward the direction close to the discharge outlet 113, and the blowing mechanism can blow air toward the discharge chamber 111 along the blowing port 114.

[0044] The waste film discharge and collection device 100 is provided with a discharge chamber 111, a feed port 112 and a discharge port 113 respectively connected to the discharge chamber 111 on the discharge chamber 110, and the discharge port 113 is connected to the accommodating chamber in the collection box 120 for collecting waste films. When the waste film enters the discharge chamber 110 along the feed port 112, the waste film can be transferred to the accommodating chamber of the collection box 120 along the discharge port 113, so as to realize the discharge and collection of the waste film. By providing an air blowing port 114 connected to the discharge chamber 111 on the outer peripheral wall of the discharge chamber 110, The blowing port 114 extends from the outside of the discharge bin 110 toward the discharge chamber 111 and is inclined toward the discharge port 113, and the blowing mechanism blows air toward the discharge chamber 111 along the blowing port 114. The gas blown into the discharge chamber 111 by the blowing mechanism can generate a negative pressure toward the discharge port 113, and the negative pressure is used to drive the waste film in the discharge chamber 111 to be discharged from the discharge port 113. Compared with the prior art, the problem that the waste film is adhered to the discharge chamber 111 and cannot be discharged normally is solved, thereby improving the discharge and collection efficiency and effect of the waste film.

[0045] Specifically, the angle of inclination of the blowing port 114 toward the direction close to the discharge port 113 is within 20° to 30°, so that the waste film in the discharge cavity 111 can be blown away from the inner cavity wall of the discharge bin 110 while generating negative pressure toward the discharge port 113. It should be noted that in this embodiment, the angle of inclination of the blowing port 114 toward the direction close to the discharge port 113 is preferably 25°. In other embodiments, the angle of inclination of the blowing port 114 toward the direction close to the discharge port 113 can also be adjusted within the range of 20° to 30° according to actual needs, and this embodiment does not make a specific limitation.

[0046] As an optional solution, the discharge bin 110 is also provided with a gas nozzle 115, wherein one end of the gas nozzle 115 is sealed and connected with the air blowing port 114, and the other end of the gas nozzle 115 is sealed and connected with the output end of the air blowing mechanism, and the gas enters the discharge chamber 111 along the gas nozzle 115 and the air blowing port 114. By providing the gas nozzle 115, one end of the gas nozzle 115 is sealed and connected with the air blowing port 114, and the other end of the gas nozzle 115 is sealed and connected with the output end of the air blowing mechanism, it can be ensured that the gas blown out by the air blowing mechanism is input into the discharge chamber 111, thereby improving the discharge effect of the waste film in the discharge chamber 111. It should be noted that, in the present embodiment, the air blowing mechanism includes a gas storage bottle and a gas transmission pipeline, and the gas in the gas storage bottle flows through the gas transmission pipeline, the gas nozzle 115 and the air blowing port 114 and then enters the discharge chamber 111. In other embodiments, the air blowing mechanism can also be a pressurized blower or other structure with a blowing function, which is not specifically limited in the present embodiment.

[0047] In an optional embodiment, a plurality of blowing ports 114 are arranged at intervals on the outer peripheral wall of the discharge bin 110, each of which extends from the outside of the discharge bin 110 toward the discharge chamber 111 and is inclined toward the discharge port 113, and each of which is connected to the blowing mechanism. By arranging a plurality of blowing ports 114 at intervals on the outer peripheral wall of the discharge bin 110, so that each of which extends from the outside of the discharge bin 110 toward the discharge chamber 111 and is inclined toward the discharge port 113, and each of which is connected to the blowing mechanism, the negative pressure generated by the gas in the discharge chamber 111 blown by the blowing mechanism can be further increased, thereby further improving the discharge effect of the waste film in the discharge chamber 111.

[0048] To further ensure the negative pressure state formed by the gas blown into the discharge chamber 111 by the blowing mechanism, as shown in FIG. Figure 3 As shown, the discharge cavity 111 includes a first cavity 1111 and a second cavity 1112, the feed port 112 is arranged at one end of the first cavity 1111 away from the second cavity 1112, and the discharge port 113 is arranged at one end of the second cavity 1112 away from the first cavity 1111, the cross-sectional area of ​​the first cavity 1111 gradually decreases as it extends toward the second cavity 1112, and the cross-sectional area of ​​the second cavity 1112 remains unchanged as it extends away from the first cavity 1111, the position with the smallest cross-sectional area in the first cavity 1111 is connected to the second cavity 1112, and the cross-sectional area of ​​the second cavity 1112 is the same as the minimum cross-sectional area of ​​the first cavity 1111.

[0049] By splitting the discharge chamber 111 into a first chamber 1111 and a second chamber 1112, the feed port 112 is set at an end of the first chamber 1111 away from the second chamber 1112, and the discharge port 113 is set at an end of the second chamber 1112 away from the first chamber 1111, the cross-sectional area of ​​the first chamber 1111 is gradually reduced as it extends toward the second chamber 1112, so that the second chamber 1112 is connected to the part with the smallest cross-sectional area in the first chamber 1111, and the cross-sectional area of ​​the second chamber 1112 remains unchanged during the extension of the second chamber 1112 away from the first chamber 1111, so that the cross-sectional area of ​​the second chamber 1112 is the same as the minimum cross-sectional area in the first chamber 1111, the effect of gradually reducing the volume of the discharge chamber 111 as the discharge chamber 111 extends toward the discharge port 113 can be achieved.

[0050] Since the blowing power of the blowing mechanism remains unchanged, the volume of the discharge chamber 111 gradually decreases towards the discharge port 113, which causes the flow rate of the gas blown toward the discharge port 113 to become faster and faster, thereby increasing the negative pressure toward the discharge port 113, ensuring the negative pressure state formed by the gas blown into the discharge chamber 111 by the blowing mechanism.

[0051] It should be noted that, in this embodiment, the ratio of the cross-sectional area of ​​the first cavity 1111 gradually decreasing as it extends toward the second cavity 1112 is constant, which makes the cross-sections of the first cavity 1111 and the second cavity 1112 funnel-shaped. In other embodiments, the ratio of the cross-sectional area of ​​the first cavity 1111 gradually decreasing as it extends toward the second cavity 1112 may be non-constant, and it is only necessary to ensure that the cross-sectional area of ​​the first cavity 1111 gradually decreases as it extends toward the second cavity 1112, and this embodiment does not make any specific limitation.

[0052] In order to further prevent the waste film from remaining in the discharge cavity 111 of the discharge bin 110, the inner cavity wall of the discharge bin 110 is coated with a coating having an anti-sticking function; or the inner cavity wall of the discharge bin 110 is mirror-polished. It should be noted that in the present embodiment, the inner cavity wall of the discharge bin 110 is coated with a Teflon coating, which has the characteristics of non-stickiness, corrosion resistance, and high temperature resistance, and has a long service life. In other embodiments, other coatings having an anti-sticking function may also be coated on the inner cavity wall of the discharge bin 110, or the inner cavity wall of the discharge bin 110 may be mirror-polished to improve the smoothness of the inner cavity wall of the discharge bin 110, so as to achieve the effect that the waste film cannot be bonded and fixed on the inner cavity wall of the discharge bin 110, which is not specifically limited in the present embodiment.

[0053] As an alternative, Figure 1 , Figure 2 as well as Figure 4 As shown, the waste film discharge collection device 100 further includes a carrier 130, wherein the collection box 120 is supported on the carrier 130, and the carrier 130 can drive the collection box 120 to move relative to the discharge bin 110. By providing the carrier 130 for carrying the collection box 120, the carrier 130 can be moved relative to the discharge bin 110. When the waste film in the collection box 120 needs to be removed, the carrier 130 can be moved to drive the collection box 120 to move to an open position relative to the discharge bin 110, and the waste in the collection box 120 can be taken out. Then, the carrier 130 is moved and drives the collection box 120 to move to the original position, so that the waste film can be taken out from the collection box 120.

[0054] Furthermore, if Figure 4As shown, the waste film discharge collection device 100 also includes a guide slider 140, wherein the guide slider 140 is fixed on the installation base, the carrier 130 is provided with a guide rail 131, the guide rail 131 extends along the first direction, and the guide slider 140 and the guide rail 131 are slidably matched. By arranging the guide rail 131 extending along the first direction on the carrier 130 and arranging the guide slider 140 on the installation base, the sliding match between the guide rail 131 and the guide slider 140 can provide guidance for the movement of the collection box 120 relative to the discharge bin 110, thereby improving the movement accuracy of the collection box 120. It should be noted that, in this embodiment, the first direction is the front-to-back direction, the discharge bin 110 is arranged above the collection box 120, and the guide rail 131 extends along the front-to-back direction. When it is necessary to remove the waste film in the collection box 120, the carrier 130 can be pulled out backward relative to the discharge bin 110 or pushed forward relative to the discharge bin 110. In other embodiments, the first direction may also be any direction, which is not specifically limited in this embodiment. In addition, a guide slider 140 may be provided on the carrier 130, and a guide rail 131 may be provided on the mounting base, which is not specifically limited in this embodiment.

[0055] To further facilitate driving the carrier 130, a handle 132 is also provided on the carrier 130.

By arranging the detection member 150 at the feed inlet 112, using the detection member 150 to detect whether there is waste film at the feed inlet 112, and enabling the air blowing mechanism to be started and stopped according to the detection information of the detection member 150, automatic discharge collection of waste film is realized, and when there is no waste film at the feed inlet 112, the air blowing mechanism is in a stopped state, saving costs.

[0057] It should be noted that, in this embodiment, the blowing mechanism also includes a solenoid valve, which is arranged on the gas pipeline, and the solenoid valve is connected to the detection member 150 by signal, and the solenoid valve can control the conduction and blocking of the gas pipeline according to the detection information of the detection member 150.
