Description

Technical Field

[0001] The utility model relates to the technical field of protective film production, in particular to an OLED protective film punching device. Background Art

[0002] With the rapid development of OLED display technology, OLED displays are widely used in various electronic products. In order to protect the OLED screen from damage during the production process, a protective film is usually attached to its surface. Now there are functional protective films such as AR anti-reflective film, AG frosted anti-reflective film, mobile phone mirror film, anti-peep film and high-definition anti-scratch film on the market. When the main screen backlight is off, the protective film acts as a mirror.

[0003] In the prior art, when the punch in the punching device moves up and resets after completing the punching work, the protective film will move up with the punch due to the friction force, resulting in bending and damage of the protective film. Utility Model Content

[0004] The present application provides an OLED protective film punching device, which can prevent the protective film from moving up with the punch after punching, thereby reducing the possibility of bending and damage to the protective film.

[0005] The present application provides an OLED protective film punching device, which adopts the following technical solution:

[0006] An OLED protective film punching device comprises a base; a placement groove is arranged on the top surface of the base; a blanking hole is arranged on the inner side wall of the bottom end of the placement groove; a bracket is fixedly connected to the top surface of the base; a cylinder is arranged on the bracket; a fixing plate located at the top of the base is fixedly connected to the output end of the cylinder; a punch is fixedly connected to the bottom surface of the fixing plate at a position corresponding to the blanking hole; the punch can be slidably matched with the inner side wall of the blanking hole; a pair of extrusion components are also arranged on the fixing plate; the pair of extrusion components can extrude the protective film to prevent the protective film from moving up with the punch.

[0007] By adopting the above technical solution, when punching the protective film, the protective film is placed in the placement groove, the cylinder is started to drive the fixed plate, the punch and the extrusion assembly to move downward, the extrusion assembly presses the protective film, the punch punches the protective film, and the punched waste is discharged through the blanking hole; when the protective film is completed after the punching, the cylinder drives the fixed plate, the punch and the extrusion assembly to move up and reset, and in the process of separation of the punch and the protective film, the extrusion assembly limits the protective film to prevent the protective film from bending and being damaged when it moves up with the punch.

[0008] Preferably, the extrusion assembly includes a shell, a slide plate and a pressure plate; the shell is fixedly connected to the top surface of the fixed plate near the side wall; the slide plate is slidably connected to the inner wall of the shell, the top surface of the slide plate is connected to the inner wall of the top end of the shell through a spring, and the bottom surface of the slide plate is fixedly connected to a sliding rod that passes through the bottom wall of the shell and extends to the bottom of the fixed plate; the pressure plate is fixedly connected to the bottom end of the sliding rod, and the bottom surface of the pressure plate is located lower than the bottom surface of the punch.

[0009] By adopting the above technical scheme, when the cylinder drives the fixed plate to move downward to prompt the punch to perform punching, the bottom surface of the pressure plate first contacts the protective film. When the punch contacts the protective film to perform punching, the pressure plate presses the protective film to maintain the stability of the protective film, and pushes the slide plate upward to compress the spring through the slide plate. When the punch completes the punching and moves up to reset, the pressure plate is always pressed on the protective film under the elastic force of the spring to limit the protective film during the separation of the punch and the protective film, thereby preventing the protective film from moving up with the punch and causing bending damage. As the punch continues to move upward, the pressure plate gradually separates from the protective film to facilitate the staff to take out the product.

[0010] Preferably, a rubber pad is fixedly connected to the bottom surface of the pressing plate.

[0011] By adopting the above technical solution, the rubber pad arranged on the bottom surface of the pressing plate protects the protective film, thereby reducing the possibility of the pressing plate causing damage to the protective film when pressing the protective film.

[0012] Preferably, the pressure plate is fixed with a ventilation pipe on the top surface close to the placement groove; the ventilation pipe side wall is fixed with an air nozzle inclined toward the placement groove; the air nozzle is connected to the inside of the ventilation pipe; and the base is provided with a blowing assembly that can supply air to the inside of the ventilation pipe.

[0013] By adopting the above technical solution, when the pressure plate moves up and down to reset, air is supplied to the ventilation pipe through the blowing component, and the gas entering the ventilation pipe is then ejected through the air nozzle. The gas ejected from the air nozzle can not only clean the surface of the protective film, but also has a downward thrust on the protective film, thereby causing the protective film to separate from the pressure plate, and reducing the possibility of the protective film adhering to the rubber pad and moving up with the pressure plate.

[0014] Preferably, the blowing assembly comprises an air pump; the air pump is mounted on the top surface of the base, an air inlet pipe connected to the external environment is fixedly connected to the input end of the air pump, and an air outlet pipe connected to the ventilation pipe is fixedly connected to the output end of the air pump.

[0015] By adopting the above technical solution, starting the air pump causes negative pressure to be generated at the end of the air inlet pipe, and the gas from the external environment is transported into the ventilation pipe through the air inlet pipe and the air outlet pipe, thereby conveniently realizing gas supply into the ventilation pipe.

[0016] Preferably, a filter is installed on the inner wall of the end of the air inlet pipe away from the pump body.

[0017] By adopting the above technical solution, the filter screen can filter the gas sucked by the air pump, reducing the possibility of dust and impurities in the external environment entering the air nozzle and causing clogging of the air nozzle.

[0018] Preferably, a material receiving box located at the bottom of the material drop hole is fixedly connected to the bottom surface of the base; one side of the material receiving box is open.

[0019] By adopting the above technical solution, the material receiving box arranged on the base is used to collect the waste dropped by punching, which is convenient for the staff to uniformly handle the waste and reduces the trouble of manual cleaning when the punching waste falls directly on the ground.

[0020] Preferably, a through hole is provided on the inner wall of the bottom end of the placement groove; an electric push rod is provided at a position on the bottom surface of the base corresponding to the through hole; a push rod is coaxially fixed to the output end of the electric push rod with a push rod extending into the through hole; the push rod is slidably fitted with the inner wall of the through hole, and the top end of the push rod is flush with the inner wall of the bottom end of the placement groove.

[0021] By adopting the above technical solution, when the protective film is punched, the electric push rod is started to drive the push rod to move up and lift the protective film, so that the protective film is moved out of the placement groove, making it convenient for the staff to take out the product.

[0022] In summary, this application has the following beneficial effects:

[0023] 1. When the cylinder drives the fixed plate and the punch to move downward for punching, the bottom surface of the pressing plate contacts the protective film first. When the punch punches the protective film, the pressing plate pushes the sliding plate through the sliding rod to deform the spring, causing the pressing plate to press the protective film. When the punch completes the punching and moves upward to reset, the pressing plate is always pressed on the protective film under the elastic force of the spring during the separation of the punch and the protective film, limiting the protective film, thereby preventing the protective film from bending and damage due to upward movement with the punch.

[0024] 2. When the pressing plate moves up and separates from the protective film, the air pump is started to suck in the gas from the external environment and transport it into the ventilation pipe. The gas is then ejected through the air nozzle to clean the surface of the protective film, so that the surface of the protective film remains clean. When the air nozzle ejects gas, it also applies a downward thrust to the surface of the protective film, so that the protective film is not easily adhered to the bottom surface of the rubber pad and moves up with the rubber pad to bend and deform, reducing the possibility of damage to the protective film.

[0025] 3. The material receiving box set on the base is used to collect the waste dropped by punching, which is convenient for the staff to uniformly handle the waste and reduce the trouble of manual cleaning when the punching waste falls directly on the ground. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom" and "top" used in the following description refer to directions in the accompanying drawings, and the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0033] The utility model discloses an OLED protective film punching device, such as Figure 1 and Figure 2 As shown, it includes a base 1, a bracket 2, a fixed plate 31 and a punch 32. The top surface of the base 1 is provided with a placement groove 11 for placing the protective film, and a blanking hole 12 vertically penetrating the base 1 is provided on the inner wall of the bottom end of the placement groove 11. The bracket 2 is fixedly connected to the top surface of the base 1. A pair of cylinders 3 are vertically arranged on the bracket 2. The output ends of the pair of cylinders 3 are located at the bottom of the top wall of the bracket 2. The fixed plate 31 is fixedly connected to the output ends of the pair of cylinders 3. The punch 32 is fixedly connected to the bottom surface of the fixed plate 31 at a position corresponding to the blanking hole 12. The punch 32 is slidably matched with the inner wall of the blanking hole 12. A material receiving box 13 located at the bottom of the blanking hole 12 is fixedly connected to the bottom surface of the base 1. The material receiving box 13 is connected to the blanking hole 12, and one side of the material receiving box 13 is open.

[0034] The protective film to be punched is placed in the placement groove 11, and the cylinder 3 is started to drive the fixed plate 31 and the punch 32 to move downward gradually. The protective film is punched by the punch 32, and the waste material punched out by the punch 32 falls into the collection box through the drop hole 12 for collection, so that the staff can uniformly handle the waste material and reduce the trouble of manual cleaning when the waste material falls on the ground.

[0035] like Figure 1 and Figure 2 As shown, a pair of extrusion components 4 are also provided on the fixed plate 31. The pair of extrusion components 4 are respectively located at the two side walls of the corresponding placement groove 11 on the fixed plate 31 away from each other. The extrusion components 4 can squeeze the protective film in the placement groove 11 to prevent the protective film from moving up with the punch 32. The extrusion components 4 include a shell 41, a slide plate 42, a slide bar 45 and a pressing plate 43. The shell 41 is fixedly connected to the top surface of the fixed plate 31, and the shell 41 vertically penetrates the fixed plate 31. The slide plate 42 is slidably connected to the fixed plate 31. On the inner wall of the shell 41, a spring 44 is fixedly connected to the top surface of the slide plate 42, and the end of the spring 44 away from the slide plate 42 is fixedly connected to the inner wall of the top end of the shell 41. The slide rod 45 is vertically fixedly connected to the bottom surface of the slide plate 42, and the bottom end of the slide rod 45 passes through the bottom wall of the shell 41 and extends to the bottom of the shell 41. The slide rod 45 and the bottom wall of the shell 41 are slidably matched, and the pressure plate 43 is fixedly connected to the bottom end of the slide rod 45. The bottom surface of the pressure plate 43 is lower than the bottom surface of the punch 32, and the bottom surface of the pressure plate 43 is fixedly connected to a rubber pad 46.

[0036] When the cylinder 3 drives the fixed plate 31 and the punch 32 to move downward for punching, the bottom surface of the pressure plate 43 first contacts the protective film. When the punch 32 punches the protective film, the pressure plate 43 pushes the slide plate 42 through the slide rod 45 to squeeze the spring 44 to deform and cause the pressure plate 43 to press the protective film, so that the protective film remains stable. When the punch 32 completes the punching and moves upward to reset, under the elastic force of the spring 44, the pressure plate 43 is always pressed on the protective film to limit the protective film during the separation of the punch 32 from the protective film, thereby avoiding the protective film from bending and damaging due to the upward movement of the punch 32. The setting of the rubber pad 46 protects the protective film and reduces the possibility of damage to the protective film caused by the squeezing effect of the pressure plate 43 on the protective film.

[0037] like Figure 1 , Figure 3 and Figure 4As shown, the two pressure plates 43 are fixedly connected with ventilation pipes 5 on the top surface near the placement groove 11, and a plurality of air nozzles 51 connected with the inside of the ventilation pipe 5 are fixedly connected on the outer wall of the ventilation pipe 5. The plurality of air nozzles 51 are arranged at intervals on the ventilation pipe 5, and the air nozzles 51 are arranged downwardly and tilted toward the side of the placement groove 11. A pair of blowing components 6 that can respectively transport air to the two ventilation pipes 5 are also provided on the base 1. The blowing component 6 includes an air pump 61, an air inlet pipe 62 and an air outlet pipe 63. The pump body is installed on the top surface of the base 1, one end of the air inlet pipe 62 is fixedly connected to the input end of the air pump 61, and the other end is connected to the external environment, one end of the air outlet pipe 63 is fixedly connected to the output end of the air pump 61, and the other end is fixedly connected to the side wall of the ventilation pipe 5 and connected with the inside of the ventilation pipe 5.

[0038] When the pressure plate 43 moves upward and separates from the protective film, the air pump 61 is started to suck in the gas from the external environment and transport it into the ventilation pipe 5. The gas in the ventilation pipe 5 is then sprayed out through the air nozzle 51 to clean the surface of the protective film, so that the surface of the protective film remains clean. When the air nozzle 51 sprays gas, it also applies a downward thrust to the surface of the protective film, which makes it difficult for the protective film to adhere to the bottom surface of the rubber pad 46 and move upward with the rubber pad 46 to bend and deform, thereby reducing the possibility of damage to the protective film.

[0039] like Figure 3 and Figure 4 As shown, a filter screen 621 is installed on the inner wall of the end of the air inlet pipe 62 away from the air pump 61.

[0040] A filter screen 621 is provided on the inner side wall of the end of the air inlet pipe 62 for filtering the gas sucked into the air inlet pipe 62, so that dust and impurities in the external environment are not easily transported into the ventilation pipe 5 to cause clogging of the air nozzle 51, thereby ensuring the smoothness of the air injection of the air nozzle 51.

[0041] like Figure 1 and Figure 5 As shown, a group of through holes 14 vertically penetrating the base 1 are provided on the inner wall at the bottom end of the placement groove 11, and electric push rods 15 are installed at positions corresponding to the group of through holes 14 on the bottom surface of the base 1. The output end of the electric push rod 15 is coaxially fixed with a push rod 151 extending into the through hole 14, and the push rod 151 is slidably matched with the inner wall of the through hole 14, and the top surface of the push rod 151 is flush with the inner wall of the bottom end of the placement groove 11.

[0042] When the protective film needs to be taken out after punching, the electric push rod 15 is started to drive the push rod 151 to move upward, so that the push rod 151 pushes the protective film out of the placement groove 11, so that the staff can take the punched protective film out of the placement groove 11.

[0043] Working principle: the protective film to be punched is placed in the placement groove 11, and the cylinder 3 is started to drive the fixed plate 31 and the punch 32 to move downward gradually, and the punch 32 punches the protective film, and the waste material punched out by the punch 32 falls into the collection box through the drop hole 12 for collection, so that the staff can uniformly handle the waste material, reducing the trouble of manual cleaning required for the waste material to fall directly to the ground; when the cylinder 3 drives the fixed plate 31 to move downward to cause the punch 32 to punch the protective film, the bottom surface of the pressing plate 43 contacts the protective film first, and when the punch 32 punches the protective film, the pressing plate 43 presses the protective film to maintain the stability of the protective film, and pushes the slide plate 42 through the slide rod 45 to squeeze the spring 44 to deform, and when the punch 32 completes the punching and moves upward to reset, the pressing plate 43 is in the process of the punch 32 separating from the protective film. 4 is always pressed on the protective film under the elastic force of the punch 32 to limit the protective film, so as to prevent the protective film from moving up with the punch 32 and causing bending and damage. As the punch 32 continues to move up, the pressing plate 43 is gradually separated from the protective film and reset to the initial position. In the process of the pressing plate 43 moving up and resetting, the pump body is started to transport the gas from the external environment to the vent pipe 5, and the gas in the vent pipe 5 is then ejected through the air nozzle 51. The gas sprayed by the air nozzle 51 can not only spray and clean the surface of the protective film, but also apply a downward thrust to the surface of the protective film, so as to separate the protective film from the rubber pad 46 and reduce the possibility of the protective film adhering to the rubber pad 46; when it is necessary to take out the workpiece, the electric push rod 15 is started to drive the push rod 151 to move up, and the push rod 151 lifts the protective film from the placement groove 11 so that the staff can take out the product.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
