Description

Technical Field

[0001] The present invention relates to the field of automation technology, and particularly to a front and rear pulling device for an automatic screen disassembling machine. Background Art

[0002] With the progress of technology, electronic products have developed rapidly. For example, smart phones have gradually transitioned from a relatively small size for easy carrying to full-screen phones with larger and larger screens and folding screen phones with larger thickness dimensions. Moreover, current mobile phones more often adopt designs with performance such as dust and water resistance, and the requirements for the integrity and sealing of mobile phones are getting higher and higher, which increases the difficulty of disassembly during the mobile phone repair process.

[0003] Currently, the panels and rear battery covers of smart phones mainly use a glue bonding fixation process. In the disassembly process, the panel needs to be heated to 65°C to make the adhesive ineffective, and then it is removed and replaced with a suction cup. However, conventional mobile phone heating platforms can only provide heating functions, and then manual disassembly is still required. Such heating platforms are inconvenient to use, and it is difficult to operate at high temperatures, resulting in low efficiency. Moreover, it is easy to cause damage to the surface of the mobile phone or scalding of personnel.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Refer to Figures 1 to 6As shown, the present invention provides a front and rear pulling device of an automatic screen disassembling machine. In one embodiment, it includes a pulling and fixing frame 1, a front pulling mechanism 2, and a rear pulling mechanism 3; the front pulling mechanism 2 includes a front pulling and lifting module 21, a first connecting rod, a suction cup rotating seat 22, and a suction cup module; the front pulling and lifting module 21 is installed on one side of the pulling and fixing frame 1, and the front pulling and lifting module 21 is also driven and connected to the pulling and lifting seat 23; one end of the first connecting rod is hinged to the upper part of one side of the pulling and lifting seat 23, and the other end of the first connecting rod is hinged to the top of the suction cup rotating seat 22 The suction cup module is detachably mounted on the bottom of the suction cup rotating seat 22, and an upper heating component is also installed in the suction cup rotating seat 22; the rear pulling mechanism 3 includes a rear pulling lifting module 31 installed on the other side of the pulling fixed frame 1, and the rear pulling lifting module 31 is also driven and connected to a pulling lifting plate 32; one end of one side of the pulling lifting plate 32 is respectively connected to a connecting arm 33, and one end of the two connecting arms 33 is respectively extended to one side of the suction cup rotating seat 22; the two sides of one end of the bottom of the suction cup rotating seat 22 are respectively rotatably connected to the inner side of a connecting arm 33.

[0031] Continue to refer to Figures 1 to 6 As shown, in this embodiment, both sides of the drawing and fixing frame 1 are equipped with slide rail assemblies in the vertical direction, and the front drawing and lifting module 21 includes a first motor and a first screw assembly connected to the output shaft of the first motor; the drawing and lifting seat 23 is slidably arranged on the slide rail assembly on one side of the drawing and fixing frame 1, and is connected to the first screw assembly. Under the drive of the first motor, the drawing and lifting seat 23 is driven to rise and fall through the first screw assembly; the rear drawing and lifting module 31 is similar to the front drawing and lifting module 21 in configuration, and also includes a motor and a screw assembly. The drawing and lifting plate 32 is slidably arranged on the slide rail assembly on the other side of the drawing and fixing frame 1, and is connected to the screw assembly. Under the mutual cooperation of the motor and the screw assembly, the drawing and lifting plate 32 can be driven to rise and fall; during operation, This device will be used in conjunction with the center clamping device of the screen removal machine. After the center clamping device lifts the product to be removed to the removal position and clamps it, the suction cup module is pressed down. At this time, the product will be completely fixed (the center clamping device clamps the four sides of the product, and the suction cup module presses and fixes the product). Then the center clamping device heats the four sides and the bottom of the product, and the upper heating component in the suction cup rotating seat 22 heats the top of the product, so that the product is quickly heated to the required temperature. After the heating is completed, the suction cup module is started to suck the screen or back cover of the product to be removed. If the front pulling mode is adopted, at this time, the front pulling lifting module 21 drives the pulling lifting seat 23 to rise, and drives the suction cup rotating seat 22 to rotate counterclockwise around the connecting arm 33 through the first connecting rod (such as Figure 5 As shown), the suction cup module slowly pulls the screen or back cover of the product to be removed from the front end of the product to a certain height at an angle and then releases the vacuum. Subsequently, the central clamping device cancels the clamping force on the left, right, front and back of the product and drives the product down, and the disassembly is completed.

[0032] If the post-pulling mode is adopted, after the suction cup module sucks the screen or the back cover of the product, the post-pulling lifting module 31 drives the pulling lifting plate 32 to rise, and then applies an upward jacking force to one end of the suction cup rotating seat 22 through the two connecting arms 33. Since the first connecting rod applies a downward pressure to the suction cup rotating seat 22, the suction cup rotating seat 22 will rotate clockwise relative to the connecting arm 33 (as Figure 6 shown), and then slowly form an angle through the suction cup module to pull the screen or the back cover of the product to be disassembled from the rear end of the product to a certain height and then release the vacuum. Subsequently, the centering clamping device cancels the clamping force on the left, right, front and back of the product and drives the product to descend, and the disassembly is completed.

[0033] In this embodiment, the pulling device supports the automatic disassembly function of the screens and rear battery covers of mobile phone products within 8 inches and below, and is compatible with common full-screen mobile phones on the market.
