After the adhesive product is affixed with adhesive backing, the bubbles between the adhesive product and the adhesive backing need to be discharged so that the adhesive backing and the surface of the adhesive product are firmly attached to each other to prevent the adhesive product from being firmly positioned during assembly through the adhesive backing. Currently, the adhesive backing of adhesive products is manually affixed using a simple adhesive jig. When the adhesive product is affixed with adhesive backing, the worker first positions the adhesive product on the jig, and then the worker sticks the adhesive backing product on the surface of the adhesive product, presses the adhesive backing by hand to make it flat with the adhesive product, and then takes the adhesive product out of the jig.

[0025] Embodiment: A back glue rolling mechanism, including a rolling module, a product positioning device and a controller, wherein the rolling module includes a rolling bracket 1, a rolling lifting slider 2, a rolling horizontal slider, a pressure roller 3, a pressure roller mounting seat 4, an elastic member 5, a rolling lifting drive device 6 and a rolling horizontal drive device, the product positioning device is provided with a product positioning groove 7, and the product 8 to be rolled can be placed in the product positioning groove 7 to be stopped, the rolling bracket 1 is fixedly arranged on one side of the product positioning device, the rolling lifting slider 2 can be installed on the rolling bracket 1 in a vertical direction, and the rolling horizontal slider can be moved in a straight line in the front-rear direction on a horizontal plane. The pressure roller 3 is installed on the pressure roller mounting seat 4 so as to rotate around a rotating shaft extending in the horizontal direction. The elastic member 5 provides a vertical downward elastic force to the pressure roller mounting seat 4. The pressure roller 3 can roll back and forth in the front and rear directions on the surface of the product 8 to be rolled in the product positioning groove 7. The rolling lifting drive device 6 and the rolling horizontal drive device respectively drive the rolling lifting slide block 2 and the rolling horizontal slide block to move. The controller controls the start and stop of the rolling lifting drive device 6 and the rolling horizontal drive device.

[0026] When in use, the glued product that has undergone preliminary gluing is placed in the product positioning device for stop positioning, and the rolling lifting slider 2 is lowered to a certain height. At this time, the pressure roller 3 is tightly pressed on one end of the back glue on the surface of the glued product under the elastic force of the elastic member 5, and due to the presence of the elastic member 5, when the pressure roller 3 descends to contact the back glue on the surface of the glued product, it will not cause damage to the glued product and the back glue on it. Then, the rolling horizontal slider slides horizontally for a distance in the front and rear directions, and the pressure roller 3 on the rolling horizontal slider rolls and squeezes back and forth on the back glue surface of the glued product, so that The bubbles between the back glue and the adhesive product are squeezed out, and the back glue is firmly adhered to the surface of the adhesive product. The mechanism realizes the fully automatic rolling and bonding of the back glue of the adhesive product. The rolling process avoids manual operation and saves labor. There are no bubbles between the back glue and the surface of the adhesive product. The back glue is firmly and stably bonded. After the back glue is bonded to the surface of the adhesive product, the adhesive surface of the adhesive product can remain flat. When it is assembled in the mobile phone later, precise assembly can be achieved. After long-term use, the adhesive product will not loosen or fall off in the mobile phone, thereby ensuring the quality of the mobile phone.

[0027] The rolling lifting slider 2 is provided with a horizontal slide 9 extending horizontally in the front-to-back direction. The rolling horizontal slider can be installed on the horizontal slide 9 in a linear sliding manner. The horizontal slide 9 is also provided with a first spur rack 10 extending in the front-to-back direction on the horizontal plane. The rolling horizontal drive device includes a motor and a gear. The motor is fixedly installed on the rolling horizontal slider. The motor power output shaft is coaxially connected to the gear, and the gear is meshed with the first spur rack 10 for transmission. The motor drives the gear to rotate, thereby realizing the front-to-back movement of the horizontal slider 9 in a linear direction. After seeing the technical solution of this application, other equivalent replacement structures that can be thought of by those skilled in the art based on this application also fall within the scope of protection of this patent, such as realizing the linear reciprocating motion of the rolling horizontal slider by driving the screw nut mechanism by a motor.

[0028] The horizontal slide 9 is provided with a linear guide rail 11 extending linearly in the front-rear direction and in the parallel direction, and the rolling horizontal slider can be installed on the linear guide rail 11 in a linearly sliding manner.

[0029] Assuming that the left and right directions on the horizontal plane are perpendicular to the front and back directions, a vertical rolling position adjustment plate 12 and a horizontal rolling position adjustment plate 13 are also provided. The vertical rolling position adjustment plate 12 is provided with at least two first long holes 14 extending in the vertical direction, and the horizontal rolling position adjustment plate 13 is provided with at least two second long holes 15 extending horizontally in the left and right directions. The vertical rolling position adjustment plate 12 is fixedly connected to the rolling horizontal slider via a connecting screw passing through the first long hole 14 so that the height can be adjusted, and the horizontal rolling position adjustment plate 13 is fixedly connected to the vertical rolling position adjustment plate 12 via a connecting screw passing through the second long hole 15 so that the left and right positions can be adjusted. By placing the first long hole 14 and the second long hole 15 on the vertical rolling position adjustment plate 12 and the horizontal rolling position adjustment plate 13, the horizontal rolling slider is made to correspond to the product positioning device at the initial up and down position and the initial left and right position, ensuring that the pressing roller 3 is aligned with the rolling position of the adhesive backing on the surface of the adhesive product, and the rolling force meets the requirements.

[0030] A first rolling horizontal slider 16 and a second rolling horizontal slider 17 are provided on one side wall of the horizontal slide 9. The first rolling horizontal slider 16 and the second rolling horizontal slider 17 are spaced apart in the front-to-back direction. A first motor 18 is fixedly mounted on the first rolling horizontal slider 16, and a second motor 19 is fixedly mounted on the second rolling horizontal slider 17. A first gear 20 and a second gear 21 are coaxially fixedly connected to the power output shafts of the first motor 18 and the second motor 19, respectively. The first gear 20 and the second gear 21 are meshed with the same straight rack for transmission, and the length of the pressure roller 3 installed on the first rolling horizontal slider 16 and the second rolling horizontal slider 17 matches the width of the front and rear ends of the product 8 to be rolled. The two pressing rollers 3 are used to roll the front and rear sections of the rolled product 8 synchronously, one in front and one behind. The rolling efficiency is high, and the back glue on the surface of the adhesive product can be prevented from being pushed and misaligned due to the slipping of one pressing roller 3. The two pressing rollers 3 of the present application press two positions of the back glue at the same time. Even if one pressing roller 3 slips, the back glue will not be driven by the slipping pressing roller 3 to shift horizontally because it is pressed by the other pressing roller 3. The two pressing rollers 3 can also move alternately, such as one pressing and rolling the other, to push the air in the middle part of the back glue to the edge, so that the air between the back glue and the surface of the adhesive product is quickly discharged.

[0031] A limit stop block 22 is fixedly disposed on one end of the horizontal slide 9 away from the side wall of the rolling lifting slide 2, and the first rolling horizontal slide 16 is stopped on the limit stop block 22 in the front of its sliding direction. The limit stop block 22 can limit the sliding distance of the first rolling horizontal slide 16 to prevent it from falling off the horizontal slide 9.

[0032] A limiting seat 23 is also fixedly installed on the other side wall of the horizontal slide 9, and a second spur rack 24 parallel to the first spur rack 10 is provided on the limiting seat 23. A third gear 25 and a fourth gear 26 can be rotatably provided on the second rolling horizontal slider 17, wherein the third gear 25 is coaxially fixedly connected to the pressure roller 3 on the second rolling horizontal slider 17, and the fourth gear 26 is meshed with the third gear 25 for transmission. A radially protruding stop rod 27 is fixedly installed on the rotating shaft of the fourth gear 26. A protruding stop block 28 is also fixedly provided on the end of the limiting seat 23 located in front of the second rack sliding along the second rolling horizontal slider 17. The radially protruding stop rod 27 on the rotating shaft of the fourth gear 26 can stop at the rear surface of the protruding stop block 28 to limit the sliding distance of the second rolling horizontal slider 17. When rolling, the pressure roller 3 on the second rolling horizontal slider 17 will drive the third gear 25 to rotate synchronously, and then transmit the fourth gear 26 to rotate. When the fourth gear 26 rolls forward along the second spur rack 24, the radially protruding baffle rod 27 thereon also rotates synchronously. When the second rolling horizontal slider 17 moves to the set front position, the radially protruding baffle rod 27 just contacts the protruding baffle block 28 on the limit seat 23, so that the fourth gear 26 cannot continue to rotate, thereby limiting the forward movement distance of the second rolling horizontal slider 17, avoiding its collision with the first rolling horizontal slider 16, and preventing its movement distance from being too large to affect the rolling efficiency.

[0033] A plurality of U-shaped first sensing devices 29 are also provided on the side wall of the horizontal slide 9 at intervals along the front-to-back direction. The first rolling horizontal slider 16 and the second rolling horizontal slider 17 are respectively fixed with L-shaped first trigger arms 30 and second trigger arms 31. One side wall of the first trigger arm 30 and the second trigger arm 31 can pass through the U-shaped space of each first sensing device 29 as the first rolling horizontal slider 16 and the second rolling horizontal slider 17 slide forward and backward. Each first sensing device 29 can sense the first trigger arm 30 and the second trigger arm 31 and transmit a signal to the controller. Through the sensing of each first sensing device 29 and the first trigger arm 30 on the first rolling horizontal slider 16 and the second trigger arm 31 on the second rolling horizontal slider 17, the controller can control the positions of the first rolling horizontal slider 16 and the second rolling horizontal slider 17, as well as the relative distance between them, so as to realize intelligent control of the movement of the two and effectively prevent the two from colliding.

[0034] The rolling support 1 is provided with a vertical guide rail 32 extending in the up-down direction, a plurality of U-shaped second sensing devices 33 arranged at intervals in the up-down direction, and a height limit stopper 34. The rolling lifting slider 2 can be slid up and down and sleeved on the vertical guide rail 32. A height trigger arm 38 is also provided on the side wall of the rolling lifting slider 2. The height trigger arm 38 can sequentially pass through the U-shaped space of each second sensing device 33 as the rolling lifting slider 2 moves up and down. Each second sensing device 33 can sense the second trigger arm 31 and transmit a signal to the controller. The lower end of the rolling lifting slider 2 stops at the height limit stopper 34 to achieve hard limit of the descending height. Through sensing by each second sensing device 33 and the height trigger arm 38 on the rolling lifting slider 2, the controller can control the lifting height of the rolling lifting slider 2 conveniently, and the height limit stopper 34 is used to hard limit the height of the rolling lifting slider 2, so as to avoid damage to the rolling product 8 when the rolling lifting slider 2 descends too high.

[0035] The product positioning device includes a turntable 35, a product positioning carrier 36 and a rotation drive device 37. The rotation drive device 37 drives the turntable 35 to intermittently rotate at a set angle. A plurality of product positioning carriers 36 are fixed on the turntable 35 at uniform intervals along the circumferential direction of the turntable 35. Each product positioning carrier 36 is provided with at least one product positioning slot 7. The controller controls the rotation drive device 37 to intermittently rotate at a set angle.

[0036] The product positioning carrier 36 can position one, two or more products to be rolled at a time, and a plurality of groups of rolling horizontal sliders can be arranged at intervals on the corresponding rolling lifting slider 2. The pressure rollers 3 on each group of rolling horizontal sliders roll different surfaces of the products 8 to be rolled respectively. When the rolling of a product 8 to be rolled on a product positioning carrier 36 is completed, the rolling lifting slider 2 rises to avoid it, and then the turntable 35 rotates a certain angle, and the group of products that have completed rolling leave the rolling position, which is convenient for their transportation and unloading. At the same time, the turntable 35 sends the next product positioning carrier 36 to the rolling position. This product positioning device can position the product while facilitating the rapid loading and unloading of the product 8 to be rolled, which is conducive to improving the rolling efficiency.
