Description

Technical Field

[0001] This utility model specifically relates to the field of mobile phone manufacturing technology, and specifically to a film-peeling machine with suction clamping function. Background Technology

[0002] To protect the surface from scratches, phone back covers are typically covered with a protective film at the factory. This film has a certain thickness, and to ensure a tight seal between the back cover and the phone body, it needs to be removed before installation to prevent tiny gaps. Some phone back covers also have a dedicated protective film covering the inner side, around areas such as the wireless charging coil and NFC antenna. These films also need to be removed before installation. Therefore, a special film-removing device is usually installed before assembly, using a mechanical mechanism to automatically remove the film and ensure assembly efficiency.

[0003] However, standard film-peeling machines only have the function of blowing and clamping to peel the film. When the protective film material is very close to the edge of the workpiece, the clamps are prone to scratching the back cover of the mobile phone when they hold the edge of the film material. This will cause scratches on the back cover of the mobile phone. Moreover, the auxiliary materials for mobile phone back covers are diverse, and standard film-peeling machines cannot meet all production needs. Utility Model Content

[0004] The purpose of this invention is to provide a film-peeling machine with a suction clamping function. There is a gap between the clamping claws and the back cover of the mobile phone to prevent scratching the back cover when the film is being removed. A suction cylinder pushes a hollow suction tube to adhere to the surface of the film, and negative pressure moves the film to the inside of the clamping claws for gripping, improving the protective effect on the back cover when the film is removed. This solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A film-tearing machine with suction clamping function includes a frame housing, a loading and unloading assembly is installed on the top of the frame housing, and a film-tearing mechanism is also provided above the loading and unloading assembly. The film-tearing mechanism is fixedly connected to the side of the film-tearing linear module, and the film-tearing linear module is fixedly connected to the frame housing through a mounting bracket on the other side.

[0006] As a further technical solution of this utility model, the side of the film-tearing linear module is also fixedly connected to an extension bracket, and the side of the extension bracket is slidably fitted with a lifting mounting frame. The film-tearing mechanism includes a lifting mounting frame, and the bottom of the lifting mounting frame is integrally provided with an extension mounting plate. The clamping cylinder and the film suction cylinder are respectively fixedly connected to the extension mounting plate.

[0007] As a further technical solution of this utility model, the film tearing mechanism also includes a film material clamping assembly for clamping the film material. The film material clamping assembly is arranged in a rectangular array. The film material clamping assembly includes a clamping cylinder. The bottom of the clamping cylinder is symmetrically fixedly connected with clamping claws. The clamping claws are arranged in an L-shape. Furthermore, the two clamping claws are integrally provided with anti-slip serrations on the side that is close to each other.

[0008] As a further technical solution of this utility model, a film suction cylinder is also provided on one side of the clamping cylinder, and a lifting connecting frame is fixedly connected to the bottom of the output rod of the film suction cylinder, and a hollow adsorption tube located on the side of the film suction cylinder is fixedly connected to the lifting connecting frame.

[0009] As a further technical solution of this utility model, the hollow adsorption tube is located above two symmetrically arranged clamping claws, and a sealing rubber head is fixedly connected to the bottom of the hollow adsorption tube. The center of the hollow adsorption tube is hollow, and the sealing rubber head is also provided with a hole communicating with the inside of the hollow adsorption tube.

[0010] As a further technical solution of this utility model, the loading and unloading assembly includes a rear cover support fixedly connected to the frame housing. The rear cover support includes a U-shaped bracket, and a material changing linear module is fixedly connected to the inner side of the U-shaped bracket. A rear cover moving frame is provided above the material changing linear module.

[0011] As a further technical solution of this utility model, the rear cover moving frame includes a transverse moving frame inserted into the inner side of the U-shaped bracket. Two sets of support rods are fixedly connected in a rectangular array above the transverse moving frame. Each set of support rods has two rods, and a rear cover adsorption pad is fixedly connected above each support rod.

[0012] As a further technical solution of this utility model, the bottom of the horizontal moving frame is symmetrically provided with dovetail-shaped sliding grooves, and each dovetail-shaped sliding groove is slidably fitted with a dovetail-shaped slider, and a lifting cylinder is fixedly connected below the dovetail-shaped slider. Multiple lifting cylinders are provided, and the lifting cylinders are arranged in a rectangular array below the transverse moving frame. Above the material changing linear module, there is a sliding sleeve and a fixed column, and the sleeve and the fixed column are fixedly connected to the material changing linear module and the transverse moving frame, respectively.

[0013] As a further technical solution of this utility model, the top of the U-shaped bracket is symmetrically fixedly connected with a support plate, and each support plate has a unidirectional air pipe connection hole opened horizontally, and a positioning adsorption hole is also opened in a rectangular array above the air pipe connection hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the output rod of the suction cylinder pushes the hollow suction tube downward through the lifting connecting frame, so that the sealing head at the bottom of the hollow suction tube adheres to the surface of the film material. The negative pressure suction component inside the frame shell extracts air from the inside of the hollow suction tube through the pipe, so that a negative pressure is formed inside the hollow suction tube. The negative pressure is used to adsorb the film material below. Then, the suction cylinder drives the hollow suction tube upward, so that the film material is moved between the two clamping claws. When the film material is sucked up, it can prevent scratching the back cover of the mobile phone, thereby improving the protection effect of the back cover of the mobile phone during the film removal process. In this invention, the film-peeling linear module moves the film clamping component below the lifting mounting frame to above the phone back cover via an extension bracket. Then, the lifting mounting frame moves the film clamping component downward, and the clamping claws stop above the phone back cover. The film is moved between the clamping claws through a hollow suction tube. There is a certain gap between the clamping claws and the phone back cover, which ensures that the film will not poke the phone back cover when it is clamped, thereby preventing the clamping claws from scratching the phone back cover and further improving the protection effect of the phone back cover. In this invention, the output rod of the lifting cylinder pushes the horizontal moving frame upward, thereby moving the support rod on the horizontal moving frame upward. Using the top of the support rod, the back cover of the phone is lifted by the back cover suction pad. Then, the material changing linear module drives the horizontal moving frame to move laterally, moving the back cover of the phone above the back cover support seat to the other side. At the same time, another set of support rods can perform the loading operation of the phone back cover while it is being unloaded, improving the efficiency of film removal.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-8 This utility model embodiment provides a film-tearing machine with suction clamping function, including a frame housing 1, a loading and unloading assembly installed on the top of the frame housing 1, and a film-tearing mechanism provided above the loading and unloading assembly. The film-tearing mechanism is fixedly connected to the side of the film-tearing straight module 3, and the film-tearing straight module 3 is fixedly connected to the frame housing 1 through the mounting bracket 2 on the other side. The film-tearing mechanism includes a film-clamping assembly 6 for holding the film material. The film-clamping assembly 6 is arranged in a rectangular array. The film-clamping assembly 6 includes a clamping cylinder 61. The bottom of the clamping cylinder 61 is symmetrically and fixedly connected with clamping claws 62. The clamping claws 62 are generally L-shaped. Furthermore, the two clamping claws 62 are integrally provided with anti-slip serrations on the side that is close to each other.

[0026] Furthermore, a film suction cylinder 63 is also provided on one side of the clamping cylinder 61, and a lifting connecting frame 64 is fixedly connected to the bottom of the output rod of the film suction cylinder 63. A hollow adsorption tube 65 located on the side of the film suction cylinder 63 is fixedly connected to the lifting connecting frame 64.

[0027] More specifically, the hollow adsorption tube 65 is located above two symmetrically arranged clamping claws 62, and a sealing head 66 is fixedly connected to the bottom of the hollow adsorption tube 65. The center of the hollow adsorption tube 65 is hollow, and the sealing head 66 also has a hole that communicates with the inside of the hollow adsorption tube 65.

[0028] By adopting the above technical solution, the output rod of the suction cylinder 63 pushes the hollow adsorption tube 65 downward through the lifting connecting frame 64, so that the sealing head 66 at the bottom of the hollow adsorption tube 65 adheres to the surface of the film material. The negative pressure adsorption component inside the frame housing 1 extracts air from the inside of the hollow adsorption tube 65 through the pipe, so that a negative pressure is formed inside the hollow adsorption tube 65. The negative pressure is used to adsorb the film material below. Then the suction cylinder 63 drives the hollow adsorption tube 65 upward, so that the film material is moved between the two clamping claws 62. There is also a certain gap between the clamping claws 62 and the back cover of the mobile phone, which can ensure that the film material will not be poked into the back cover of the mobile phone when it is clamped, thereby preventing the clamping claws 62 from scratching the back cover of the mobile phone when clamping, and further improving the protection effect of the back cover of the mobile phone.

[0029] Furthermore, the side of the film-tearing linear module 3 is also fixedly connected to an extension bracket 4, and the side of the extension bracket 4 is slidably fitted with a lifting mounting frame 5. The bottom of the lifting mounting frame 5 is integrally provided with an extension mounting plate 51, and the clamping cylinder 61 and the film suction cylinder 63 are respectively fixedly connected to the extension mounting plate 51.

[0030] More specifically, the loading and unloading assembly includes a rear cover support 7 fixedly connected to the frame housing 1. The rear cover support 7 includes a U-shaped bracket 71. A material changing linear module 9 is also fixedly connected to the inner side of the U-shaped bracket 71, and a rear cover moving frame 8 is provided above the material changing linear module 9.

[0031] Furthermore, the top of the U-shaped bracket 71 is symmetrically fixedly connected with a support plate 72. Each support plate 72 has a unidirectional air pipe connection hole 74 opened laterally, and above the air pipe connection hole 74, a positioning adsorption hole 73 is also opened in a rectangular array.

[0032] By adopting the above technical solution, the material is placed above the support plate 72 by the back cover moving frame 8, and the back cover of the mobile phone completely covers the positioning adsorption hole 73. At this time, the negative pressure adsorption component will extract the air inside the air pipe connection hole 74, so that the air pipe connection hole 74 forms a negative pressure. Since the air pipe connection hole 74 and the positioning adsorption hole 73 are connected, and the back cover of the mobile phone completely covers the positioning adsorption hole 73, the negative pressure can stably adsorb the back cover of the mobile phone above the support plate 72.

[0033] Furthermore, the rear cover moving frame 8 includes a transverse moving frame 81 inserted into the inner side of the U-shaped bracket 71. Two sets of support rods 82 are fixedly connected in a rectangular array above the transverse moving frame 81. One set of support rods 82 is located between symmetrically arranged support plates 72, and the other set is located at one end of the support plate 72. Each set of support rods 82 has two, and each support rod 82 is fixedly connected to a rear cover adsorption pad 83.

[0034] More specifically, the bottom of the horizontal moving frame 81 is symmetrically provided with dovetail-shaped grooves 85, and each dovetail-shaped groove 85 is slidably fitted with a dovetail-shaped slider 86, and a lifting cylinder 84 is fixedly connected below the dovetail-shaped slider 86. Multiple lifting cylinders 84 are provided, and the lifting cylinders 84 are arranged in a rectangular array below the transverse moving frame 81. The material changing linear module 9 is also provided with a sliding sleeve and a fixed column above it, and the sleeve and the fixed column are fixedly connected to the material changing linear module 9 and the transverse moving frame 81, respectively.

[0035] By adopting the above technical solution, the output rod of the lifting cylinder 84 pushes the horizontal moving frame 81 to move upward, thereby causing the support rod 82 on the horizontal moving frame 81 to move upward. Using the top of the support rod 82, the back cover of the mobile phone is lifted by the back cover suction pad 83. Then, the material changing linear module 9 drives the horizontal moving frame 81 to move laterally, moving the back cover of the mobile phone above the back cover support seat 7 to the other side. At the same time, another set of support rods 82 can perform the loading operation of the back cover of the mobile phone while it is being unloaded, improving the efficiency of film removal.

[0036] Furthermore, a collection funnel 10 is embedded above the frame housing 1, and the collection funnel 10 is located behind the loading and unloading assembly. After the clamping claw 62 clamps the film material, the film tearing linear module 3 drives the film material clamping assembly 6 to move backward as a whole through the extension bracket 4 and the lifting mounting bracket 5, tearing off the film material on the back cover of the mobile phone and moving it above the collection funnel 10. After the clamping claw 62 releases, the film material will fall downward into the collection funnel 10.

[0037] Furthermore, the inner side of the frame housing 1 is also provided with a negative pressure adsorption assembly, including a vacuum pump, a vacuum pipeline and a control valve. The air inlet of the vacuum pump is connected to the control valve through the vacuum pipeline, and the other side of the control valve is connected to the end of the hollow adsorption tube 65 and the opening of the air pipe connection hole 74 through the vacuum pipeline. The control valve is a three-way valve with two working states. When open, it connects the vacuum pump to the hollow adsorption tube 65 or the air pipe connection hole 74, drawing air from inside to create negative pressure. When closed, it connects the hollow adsorption tube 65 or the air pipe connection hole 74 to the outside, allowing outside air to enter the inside of the hollow adsorption tube 65 or the air pipe connection hole 74 through the control valve, balancing the other air inside and causing it to lose its adsorption effect.

[0038] More specifically, when the sealing head 66 below the hollow adsorption tube 65 is attached to the surface of the abrasive, the control valve is opened, and the vacuum pump will extract the air inside the hollow adsorption tube 65 to form a negative pressure, causing the film material on the surface of the phone back cover to be adsorbed under the sealing head 66. After the film material is moved between the symmetrically arranged clamping claws 62, the control valve is closed, so that it loses its adsorption effect.

[0039] Furthermore, when the phone back cover is placed above the support plate 72, the control valve in the vacuum pipe connected to the air pipe connection hole 74 is opened, using negative pressure to fix the phone back cover on the support plate 72, preventing the phone back cover from shifting when the film is peeled off. When the support rod 82 lifts the phone back cover upwards, the control valve closes, allowing external air to enter the inside of the air pipe connection hole 74, ensuring the normal movement of the phone back cover.

[0040] Furthermore, the extension bracket 4 and the lifting mounting frame 5 are slidably coupled, and an electric push rod is fixedly connected to the inner side of the lifting mounting frame 5. The other end of the electric push rod is connected to the extension bracket 4, and the lifting mounting frame 5 can be pushed to slide up and down on the side of the extension bracket 4 by the electric push rod.

[0041] The working principle of this utility model is as follows: In use, the phone back cover is first placed on the back cover adsorption pad 83 on the side away from the support plate 72. The lifting cylinder 84 pushes the horizontal moving frame 81 upwards, making the collecting back cover higher than the support plate 72. Then, the material changing linear module 9 drives the horizontal moving frame 81 to move laterally through the sleeve and fixed column, moving the support rod 82 on the side away from the support plate 72 to between the symmetrically arranged support plates 72, thereby moving the phone back cover above the support rod 82 to above the support plate 72. Then, the lifting cylinder 84 drives the horizontal moving frame 81 downwards through the dovetail-shaped slide 85, making the back cover adsorption pad 83 on the horizontal moving frame 81 lower than the support plate 72. At the same time, the material changing linear module 9 also drives the horizontal moving frame 81 to move to the end away from the U-shaped bracket 71 to reset it. Then, the phone back cover is adsorbed onto the support plate 72 by negative pressure. The film peeling linear module 3 drives the film clamping assembly 6 to move to the upper end of the phone back cover through the extension bracket 4 and the lifting mounting frame 5. Then, the lifting mounting frame 5... The extended mounting plate 51 drives the film clamping assembly 6 downwards, and a certain gap is maintained between the bottom of the clamping claw head 62 and the back cover of the mobile phone. The output rod of the suction cylinder 63 pushes the hollow suction tube 65 downwards through the lifting connecting frame 64, so that the sealing head 66 at the bottom of the hollow suction tube 65 adheres to the surface of the film. The negative pressure suction assembly inside the frame housing 1 extracts air from the inside of the hollow suction tube 65 through the pipe, so that a negative pressure is formed inside the hollow suction tube 65, and the film is adsorbed below by the negative pressure. Then, the suction cylinder 63 drives the hollow suction tube 65 to move upward, so that the film material moves between the two clamping claws 62. Then, the clamping cylinder 61 drives the symmetrically arranged clamping claws 62 to move closer together to clamp the film material. Then, the film tearing linear module 3 drives the film material clamping assembly 6 to move backward as a whole, tearing off the film material of the phone back cover and moving the film material above the collection funnel 10. The collection funnel 10 is used to collect the torn film material. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
