As shown in fig. 1 and 2, the electronic product 10 includes a housing 11 and a display 12 mounted on the housing 11, and a protective film 13 is attached to a surface of the display 12. In a production workshop, if a quality inspector finds that electronic products have defects such as quality and the like in the process of detecting the electronic products, particularly when batch electronic products have the same quality problem, the quality inspector needs to perform rework treatment on the electronic products so as to solve the quality problem found in the detection process. During the rework process of the electronic product, the protective film 13 is firstly torn off from the display 12 to facilitate the removal of the display 12 from the housing 11 or the maintenance of the display 12.
For this purpose, an electronic product rework apparatus is particularly provided for performing a rework process on the electronic product 10, specifically, tearing off the protective film from the display screen. In particular, as long as the protective film is attached to the display screen of the electronic product, the protective film can be torn off from the display screen by using the electronic product reworking equipment.
The electronic product reworking apparatus includes: a transfer mechanism 20 (shown in fig. 4), an adhesive applying mechanism 30 (shown in fig. 6), and a film tearing mechanism 40 (shown in fig. 11).
The gluing mechanism 30 and the film tearing mechanism 40 are sequentially arranged along the conveying direction of the conveying mechanism 20.
The conveying mechanism 20 is used for conveying the electronic product 10 to the gluing mechanism 30 and the film tearing mechanism 40 in sequence.
The adhesive sticking mechanism 30 is used for sticking the adhesive tape on the protective film 13 of the display screen 12, and the film tearing mechanism 40 is used for tearing the adhesive tape and the protective film from the display screen.
It should be noted that, as shown in fig. 3, one half of the adhesive paper 31 (attached to the protective film 13) is adhered to the protective film 13, and the other half is exposed outside the protective film 13, so that the film tearing mechanism 40 can easily grip the adhesive paper, and tear the adhesive paper and the protective film from the display screen. Obviously, because the edge of the protective film is not exposed outside the display screen, the related manipulator cannot well find the stress point for tearing off the protective film, which brings difficulty to the tearing off work of the protective film. Therefore, in order to more conveniently tear the protective film from the display screen, a layer of gummed paper needs to be pasted on the protective film, half of the gummed paper is adhered to the protective film, and the other half of the gummed paper is exposed out of the protective film.

The left conveying device 120 comprises a left conveying frame 121 and a left conveyor belt 122 arranged on the left conveying frame 121; the right transfer device 130 includes a right transfer frame 131 and a right transfer belt (not shown) disposed on the right transfer frame 131, and the transfer driving unit 140 is drivingly connected to the left transfer belt 122 and the right transfer belt.
In this embodiment, the left transmission frame 121 is an elongated frame structure, the right transmission frame 131 is an elongated frame structure, the left conveyor belt 122 is a belt structure, the right conveyor belt is a belt structure, and the transmission driving part 140 is a motor. Further, the motor is a servo motor.
The operation principle of the transmission mechanism 20 will be explained below:
placing the electronic product to be reworked on the transmission mechanism 20, and sequentially transmitting the electronic product 10 to the adhesive sticking mechanism 30 and the film tearing mechanism 40 by the transmission mechanism 20;
specifically, one side of the electronic product 10 is pressed on the left conveyor belt 122 of the left transport rack 121, and the other side of the electronic product 10 is pressed on the right conveyor belt of the right transport rack 131;
the transmission driving portion 140 drives the left conveyor belt 122 and the right conveyor belt to perform a transmission motion, so that the left conveyor belt 122 and the right conveyor belt can drive the electronic product 10 thereon to move along one side of the horizontal direction, and thus reach the adhesive applying mechanism 30 and the film tearing mechanism 40 in sequence.
As shown in fig. 5, further, the transferring mechanism 20 further includes a spacing adjusting device 150. The spacing adjustment device 150 includes: an adjusting handwheel 151, an adjusting screw rod 152, an adjusting guide rod 153, a left adjusting slide block 154 and a right adjusting slide block 155. The adjusting screw 152 is rotatably arranged on the transmission base 110, the adjusting guide rod 153 is fixedly arranged on the transmission base 110, the axis of the adjusting screw 152 is parallel to the axis of the adjusting guide rod 153, and the adjusting hand wheel 151 is arranged at one end of the adjusting screw 152. Screw holes and guide holes are formed in the left-side adjusting sliding block 154, the adjusting screw 152 is screwed with the screw holes of the left-side adjusting sliding block 154, and the adjusting guide rod 153 penetrates through the guide holes of the left-side adjusting sliding block 154. Screw holes and guide holes are formed in the right adjusting sliding block 155, the adjusting screw 152 is screwed with the screw holes of the right adjusting sliding block 155, and the adjusting guide rod 153 penetrates through the guide holes of the right adjusting sliding block 155. The left transmission frame 121 is disposed on the left adjustment slider 154, and the right transmission frame 131 is disposed on the right adjustment slider 155.
Next, the operation principle of the pitch adjustment device 150 will be explained:
rotatory adjusting hand wheel 151, adjusting hand wheel 151 and then drive adjusting screw 152 and rotate, because adjusting screw 152 threads with the screw of left side adjusting sliding block 154 and the screw of right side adjusting sliding block 155, and under the cooperation of adjusting guide rod 153, then, left side adjusting sliding block 154 and right side adjusting sliding block 155 alright be close to each other or keep away from, and then drive left side transmission frame 121 and right side transmission frame 131 on it respectively and be close to each other or keep away from, the regulation of distance has been realized, thereby can transmit the electronic product of different size of a dimension, compatibility has been improved.
As can be seen from the above, in order to improve the compatibility of transmitting electronic products with different sizes, the distances between the left transmission rack 121 and the right transmission rack 131 need to be adjusted adaptively. However, as described above, the left side conveyor belt 122 and the right side conveyor belt can be driven simultaneously by providing one transfer driving unit 140. Therefore, how to further optimize the structure of the transfer driving part 140 is to adjust the distance between the transfer racks so that the transfer driving part 140 does not affect the simultaneous driving of the left side transfer belt 122 and the right side transfer belt. The following modifications are made, and the transfer mechanism 20 further includes: a power transmission shaft 161, a left follower slider 162, and a right follower slider 163. Driven slider 162 in left side is fixed in on the transmission frame 121 in left side, driven slider 163 in right side is fixed in on the transmission frame 131 in right side, be equipped with left side drive roller 164 on the driven slider 162 in left side, be equipped with right side drive roller 165 on the driven slider 163 in right side, power transmission axle 161 wears to locate left side driven slider 162 and right side driven slider 163, left side drive roller 164 and right side drive roller 165 cup joint on power transmission axle 161, the one end of power transmission axle 161 is connected with the output that transmits drive portion 140. The left conveyor belt 122 is wound around a left drive roller 164 and the right conveyor belt is wound around a right drive roller 165.
It can be seen that, through such a structural improvement, a transmission driving portion 140 drives the power transmission shaft 161 to rotate, the power transmission shaft 161 further drives the left driving roller 164 and the right driving roller 165 to rotate, and the left driving roller 164 and the right driving roller 165 respectively drive the left conveyor belt 122 and the right conveyor belt to perform transmission motion, thereby realizing the transmission of the electronic product. Further, because the power transmission shaft 161 penetrates through the left driven slider 162 and the right driven slider 163, even if the left transmission frame 121 and the right transmission frame 131 perform distance adjustment, the left driven slider 162 and the right driven slider 163 can slide along the power transmission shaft 161, so that the problem that the transmission driving part 140 is influenced to simultaneously drive the left conveyor belt 122 and the right conveyor belt by adjusting the distance between the transmission frames is solved.
The following explains the structure of the taping mechanism 30 and the connection relationship between the respective members:

The cutter mounting frame 520 is slidably disposed on the rubberizing base 200, the mounting frame driving portion 510 is drivingly connected to the cutter mounting frame 520, and the mounting frame driving portion 510 drives the cutter mounting frame 520 to reciprocate in the horizontal direction. The cutting knife 530 includes an upper cutting knife 531 and a lower cutting knife 532, the lower cutting knife 532 is fixed on the knife mounting frame 520, one end of the upper cutting knife 531 is hinged to one end of the lower cutting knife 532, the output end of the knife shearing driving part is connected to or separated from the upper cutting knife 531, so that the cutting edge of the upper cutting knife 531 and the cutting edge of the lower cutting knife 532 are close to or far away from each other.
The gummed paper cutter scissors 530 are positioned between the gumming roller 420 and the gummed paper pasting wheel 350.
In the present embodiment, the swing driving part 330 is a cylinder driving structure; the glue pressing driving part 410 is a cylinder driving structure; the mount driving part 510 is a cylinder driving structure; the cutter shearing driving part is of a cylinder driving structure.
The operation of the taping mechanism 30 will be explained as follows:
firstly, a roll of adhesive tape 31 is placed on an adhesive tape unwinding wheel 310 of the gluing device 300, and the adhesive tape unwinding wheel 310 is used for unwinding the roll of adhesive tape;
the continuous and uninterrupted adhesive tape from the adhesive tape unwinding wheel 310 is wound on the adhesive tape guide wheel 340, passes through the adhesive tape anti-retraction structure 360 and then reaches the adhesive tape pasting wheel 350;
it should be noted that the adhesive tape guide wheel 340 has a guiding function for the continuous and uninterrupted adhesive tape, and can guide the continuous and uninterrupted adhesive tape to the adhesive tape anti-retraction structure 360, and the continuous and uninterrupted adhesive tape passes through the adhesive tape anti-retraction structure 360 and then reaches the adhesive tape sticking wheel 350;
it is further noted that the anti-shrinking structure 360 is used for temporarily fixing the adhesive tape, and when the adhesive tape needs to be adhered to the protective film of the electronic product, the anti-shrinking structure 360 loosens the fixation of the adhesive tape, so that one end of the adhesive tape can be adhered to the protective film, and the continuous and uninterrupted adhesive tape is pulled out from the adhesive tape unwinding wheel 310; after the adhesive tape is adhered to the protective film and cut off, the adhesive tape shrinkage-preventing structure 360 temporarily fixes the adhesive tape to prevent the adhesive tape at the adhesive tape adhering wheel 350 from shrinking due to the pulling force of the adhesive tape unwinding wheel 310, and it can be known that once the adhesive tape shrinks, the adhesive tape does not exist at the adhesive tape adhering wheel 350 any more, so that the adhesive tape cannot be smoothly adhered to the protective film of the next electronic product;
when the gummed paper is arranged at the gummed paper pasting wheel 350, the output end of the swinging driving part 330 extends out to further drive the gummed paper large swing arm 320 to rotate for an angle around the gummed base 200, at this time, the electronic product 10 is positioned below the gummed paper pasting wheel 350, the gummed paper pasting wheel 350 positioned at the swinging end 322 of the gummed paper large swing arm 320 can be pressed on the protective film of the electronic product, and then the gummed paper at the gummed paper pasting wheel 350 can be pasted on the protective film;
the electronic product continues to move forward under the action of the transmission mechanism 20, and then the movement of the electronic product pulls the adhesive tape unwinding wheel 310 to unwind the adhesive tape;
after one end of the gummed paper is pasted on the protective film, the swing driving part 330 drives the big gummed paper swing arm 320 to rotate around the gummed base 200 in the opposite direction for an angle, so that the subsequent gummed paper which is not pasted on the protective film is slightly lifted for an angle, and thus the gummed paper which is not pasted forms an included angle with the protective film of the electronic product, and the gummed paper is conveniently cut by the gumming device 500;
meanwhile, the glue pressing device 400 works, specifically, the output end of the glue pressing driving part 410 extends out, so that the glue pressing roller 420 can press the gummed paper of the protective film on the electronic product, and the electronic product can continuously move forward under the action of the transmission mechanism 20, so that the glue pressing roller 420 can roll to press the gummed paper on the protective film;
as the electronic product moves forward, part of the adhesive tape will be adhered to the protective film, and part of the adhesive tape will extend out of the protective film, and at this time, the adhesive tape extending out of the protective film needs to be cut by the adhesive cutting device 500;
the adhesive tape shearing device 500 works, the mounting frame driving part 510 pushes the cutter mounting frame 520, so that the adhesive tape cutter shears 530 on the cutter mounting frame 520 reach the adhesive tape to be sheared, specifically, the adhesive tape to be sheared is positioned between the cutting edge of the upper adhesive tape cutter 531 and the cutting edge of the lower adhesive tape cutter 532, and then, the output end of the cutter shearing driving part extends out and is pressed on the upper adhesive tape cutter 531, so that the cutting edge of the upper adhesive tape cutter 531 and the cutting edge of the lower adhesive tape cutter 532 are close to each other, and the adhesive tape positioned between the cutting edges can be sheared;
after the adhesive tape is cut, the electronic product will continue to move forward under the action of the conveying mechanism 20, and then reach the film tearing mechanism 40, and the adhesive tape and the protective film are torn off from the display screen of the electronic product by the film tearing mechanism 40.
Further, the adhesive tape unwinding wheel 310 is provided with an adhesive tape positioning structure. The adhesive tape positioning structure comprises a plurality of positioning blades 312 (as shown in fig. 7), the plurality of positioning blades 312 are disposed on the wheel surface of the adhesive tape unwinding wheel 310, and the plurality of positioning blades 312 are distributed in an annular array with the rotation shaft of the adhesive tape unwinding wheel 310 as the center. In the present embodiment, the number of the positioning blades 312 is three. Due to the structural design, one side surface of the rolled adhesive tape is tightly attached to the positioning blade 312 through the positioning effect of the adhesive tape positioning structure, so that the rolled adhesive tape can be accurately and quickly placed on the adhesive tape unwinding wheel 310.
It should be particularly noted that the glue pressing roller 420 can press the glue paper on the protective film, so as to make provision for the subsequent protective film to be able to be stably torn off from the display screen; the glue pressing roller 420 is also effectively matched with the gummed paper shrinkage-proof structure 360, when the gummed paper needs to be cut off, the gummed paper shrinkage-proof structure 360 can fix the gummed paper at one end, the gummed paper at the other end is compacted by the glue pressing roller 420, and then the gummed paper is in a tight state, so that the gummed paper can be cut off more stably.
As shown in fig. 9, further, the adhesive paper shrinkage prevention structure 360 includes: the adhesive tape adsorption device comprises an adhesive tape supporting plate 361 and an adhesive tape adsorption cover 362, wherein the adhesive tape supporting plate 361 is of a flat plate structure, and the adhesive tape adsorption cover 362 is of a flat plate structure.
Referring to fig. 10, the surface of the adhesive tape adsorbing cover 362 is provided with an adhesive tape left guide strip 363 and an adhesive tape right guide strip 364, and the adhesive tape left guide strip 363 and the adhesive tape right guide strip 364 are parallel to each other and are spaced apart from each other. The surface of the adhesive tape adsorbing cover 362 is provided with a vacuum suction hole 365, and the vacuum suction hole 365 is located between the adhesive tape left guide strip 363 and the adhesive tape right guide strip 364. The adhesive tape suction cover 362 is further provided with a vacuum suction pipe 366, and the vacuum suction pipe 366 is communicated with the vacuum suction hole 365.
The adhesive tape adsorbing cover 362 is mounted on the adhesive tape supporting plate 361, the left adhesive tape guiding strip 363 and the right adhesive tape guiding strip 364 are pressed on the surface of the adhesive tape supporting plate 361, and an adhesive tape unwinding channel 367 (as shown in fig. 9) is formed between the adhesive tape adsorbing cover 362 and the adhesive tape supporting plate 361.
The surface of the adhesive paper supporting plate 361 is provided with an adhesive paper anti-sticking bump 368 (as shown in fig. 9), and the adhesive paper anti-sticking bump 368 is located at the opening of the adhesive paper unwinding channel 367.
The working principle of the above-mentioned structure of the anti-shrinking structure 360 is explained as follows:
firstly, it should be noted that the adhesive tape on the adhesive tape unwinding wheel 310 passes through the adhesive tape unwinding channel 367 between the adhesive tape adsorption cover 362 and the adhesive tape support plate 361 when unwinding;
when the gummed paper needs to be cut off, the gummed paper shrinkage-preventing structure 360 needs to temporarily fix the gummed paper, specifically, the external vacuum generating device vacuumizes the vacuum suction holes 365 through the vacuum suction pipe 366, so that the gummed paper in the gummed paper unreeling channel 367 is adsorbed on the plate surface of the gummed paper adsorption cover 362, and thus, the temporary fixation of the gummed paper can be realized, and favorable conditions are created for the cutting of the gummed paper;
when the adhesive tape needs to be unreeled, the adhesive tape shrinkage prevention structure 360 does not need to fix the adhesive tape, so that the adhesive tape can smoothly unreel the channel 367 through the adhesive tape, conceivably, when the adhesive tape is not adsorbed on the surface of the adhesive tape adsorption cover 362 any more, the adhesive tape can slightly sag under the action of gravity, and therefore, the adhesive tape support plate 361 is particularly arranged to support the adhesive tape and prevent the adhesive tape from sagging;
the adhesive paper is supported by the adhesive paper supporting plate 361, however, the adhesive paper has viscosity, so that the adhesive paper with viscosity can be adhered to the plate surface of the adhesive paper supporting plate 361 in a large area, and thus the smooth unwinding of the adhesive paper can be influenced, and therefore, the adhesive paper anti-sticking bump 368 is particularly arranged on the adhesive paper supporting plate 361, the adhesive paper anti-sticking bump 368 is protruded out of the plate surface of the adhesive paper supporting plate 361, and the adhesive paper anti-sticking bump 368 jacks up the adhesive paper, so that only a small part of the adhesive paper in the adhesive paper unwinding channel 367 can be adhered to the adhesive paper anti-sticking bump 368, and most of the adhesive paper can not be adhered to the plate surface of the adhesive paper supporting plate 361, and thus, the adhesive paper can be separated from the adhesive paper anti-sticking bump 368 only by applying a small external force to the adhesive paper, so that the adhesive paper can be smoothly unwound;
it should be further noted that the surface of the adhesive tape adsorption cover 362 is provided with an adhesive tape left guide strip 363 and an adhesive tape right guide strip 364, and by providing the adhesive tape left guide strip 363 and the adhesive tape right guide strip 364, on one hand, the adhesive tape in unwinding can be guided and limited to prevent the adhesive tape from deviating, and on the other hand, the adhesive tape left guide strip 363 and the adhesive tape right guide strip 364 also provide conditions for forming the adhesive tape unwinding channel 367.

The main film tearing driving part 620 is in driving connection with the horizontal moving plate 640, and the main film tearing driving part 620 drives the horizontal moving plate 640 to reciprocate along the horizontal direction.
As shown in fig. 12, the electronic product pressing means 670 includes: a press-down driving part 671, and a press-down roller 672. The pressing driving portion 671 is in driving connection with the pressing roller 672, and the pressing driving portion 671 drives the pressing roller 672 to reciprocate up and down along the vertical direction. In this embodiment, the pressing driving portion 671 is an air cylinder driving structure, and the wheel surface of the pressing roller 672 is wrapped with a rubber sleeve. Through setting up the rubber sleeve, can carry out effectual protection to the display screen of electronic product.
The operation of the film tearing mechanism 40 will be explained below:
after the adhesive tape is adhered to the protective film of the electronic product, the transmission mechanism 20 transmits the electronic product from the adhesive tape adhering mechanism 30 to the film tearing mechanism 40, and the adhesive tape and the protective film are torn off from the display screen of the electronic product by the film tearing mechanism 40;
firstly, the gummed paper clamping device 660 works, and the gummed paper clamping device 660 clamps gummed paper outside the protective film;
then, the main driving part 620 drives the horizontal moving plate 640 to move along one side of the horizontal direction, because the horizontal transmission rack 635 is fixed on the film tearing support frame 610, and the horizontal transmission gear 631 is meshed with the tooth slot of the horizontal transmission rack 635, then the horizontal transmission gear 631 rotates to drive the middle transmission shaft 633 to rotate, and the middle transmission shaft 633 drives the vertical transmission gear 632 to rotate;
because the vertical transmission rack 636 is fixed on the vertical lifting plate 650, and the vertical transmission gear 632 is meshed with the tooth socket of the vertical transmission rack 636, then the rotating vertical transmission gear 632 drives the vertical lifting plate 650 to ascend along the vertical direction, and the vertical lifting plate 650 drives the gummed paper clamping device 660 to ascend;
therefore, after the gummed paper clamping device 660 clamps gummed paper, the film tearing main driving part 620 drives the horizontal moving plate 640 to move along one side in the horizontal direction, and under the coordination of the power transmission device 630, one side of the vertical lifting plate 650 can perform translational motion along one side in the horizontal direction, and one side of the vertical lifting plate 650 can also perform lifting motion along the vertical direction, so that the gummed paper clamping device 660 arranged on the vertical lifting plate 650 can simultaneously realize motion in two degrees of freedom, namely horizontal and vertical;
thus, when the gummed paper clamping device 660 clamps the gummed paper for tearing, the gummed paper clamping device 660 can lift the gummed paper and the protective film while stripping the gummed paper and the protective film, so that the stripped gummed paper and the stripped protective film can be delivered to a specified position, and then the relevant waste material collecting device removes the gummed paper and the protective film at the gummed paper clamping device 660;
when the gummed paper clamping device 660 peels off the gummed paper and the protective film, the electronic product pressing device 670 also cooperates with the gummed paper clamping device 660 to act, and the pressing driving part 671 drives the pressing roller 672 to descend along the vertical direction, so that the pressing roller 672 can press the protective film and simultaneously press the display screen of the electronic product; because the electronic product pressing device 670 is mounted on the horizontal moving plate 640, when the horizontal moving plate 640 moves horizontally to one side, the pressing roller 672 on the electronic product pressing device 670 also moves horizontally to one side, so that a vacancy is avoided for smooth tearing of the protective film from the display screen; it can be known that the electronic product pressing device 670 well cooperates with the adhesive tape clamping device 660, when the adhesive tape clamping device 660 is tearing off the protective film, the electronic product itself can be pressed on the transmission mechanism 20, so as to prevent the electronic product from being separated from the transmission mechanism 20.
It should be noted that, when the electronic product is placed on the transmission mechanism 20, one side of the electronic product 10 is pressed on the left conveyor belt 122 of the left transmission rack 121, and the other side of the electronic product 10 is pressed on the right conveyor belt of the right transmission rack 131, so that the transmission mechanism 20 is configured to facilitate rapid placement of the electronic product on the assembly line, and to facilitate rapid taking of the electronic product from the assembly line. However, when the electronic product is placed and taken conveniently, a problem may occur that the electronic product is subjected to an upward external force during the process of tearing the protective film by the film tearing mechanism 40, and if the electronic product is not fixed, the electronic product is separated from the production line. Therefore, the electronic product pressing device 670 is particularly arranged, and the electronic product pressing device 670 applies a pressing force to the electronic product, so that the electronic product can be pressed on the production line, and the tearing work of the adhesive tape clamping device 660 on the protective film is well matched.
As shown in fig. 12, further, the offset paper clamping device 660 includes: an overturning driving part 661, an overturning bracket 662 and a clamping manipulator 663.

In this embodiment, the number of the gripping manipulators 663 is plural, the gripping manipulators 663 are linearly arranged on the overturning bracket at intervals in sequence, and the overturning driving part 661 is of a motor-driven structure. Thus, the turnover driving part 661 drives the turnover support 662 to rotate, and further drives the clamping manipulator 663 to rotate, so that the adhesive paper and the protective film on the clamping manipulator 663 can be turned over by a certain angle, and the adhesive paper and the protective film on the clamping manipulator 663 can be conveniently removed by a related recovery device.
As shown in fig. 12, further, the film tearing mechanism 40 further includes a support frame horizontal driving portion 680, the support frame horizontal driving portion 680 is in driving connection with the film tearing support frame 610, and the support frame horizontal driving portion 680 drives the film tearing support frame 610 to reciprocate along the horizontal direction. In this embodiment, the supporting frame horizontal driving part 680 is a cylinder driving structure. Thus, after the gummed paper clamping device 660 tears off the gummed paper and the protective film, the supporting frame 610 can be horizontally moved by arranging the supporting frame horizontal driving part 680, so that the gummed paper and the protective film on the gummed paper clamping device 660 can be delivered to a specified position, and the gummed paper and the protective film are torn off from the gummed paper clamping device 660 by the related waste recovery device.
