[0002] The battery of an electronic product is usually fixed on the electronic product by means of battery back adhesive and pasting. When the electronic product is repaired or the battery is replaced, the back adhesive needs to be removed to dismount the battery from the electronic product. Generally, the back adhesive is manually dismounted, which is inconvenient for fixing the electronic product and removing the back adhesive, resulting in low dismounting efficiency of the back adhesive. CONTENT

[0003] Therefore, the present application provides a dismounting device to solve the problem of inconvenience in fixing the electronic product and removing the back adhesive when the back adhesive is manually dismounted, thereby improving the dismounting efficiency of the back adhesive.

[0004] The present application provides a dismounting device, which comprises a carrier plate, a positioning assembly and a winding member. The carrier plate is used for carrying an electronic product. The positioning assembly is arranged on the carrier plate and is used for positioning the electronic product. The winding member is arranged on one side of the carrier plate and is used for winding the back adhesive of the electronic product.

[0005] In the above embodiment, the electronic product on the carrier plate is fixed by the positioning assembly, and the back adhesive on the electronic product is wound by the winding member to remove the back adhesive, thereby improving the dismounting efficiency of the back adhesive.

[0006] In some embodiments, the winding member has a winding surface for contacting the back adhesive, and the winding surface is provided with a fixing structure for fixing the end of the back adhesive.

[0007] The fixing structure is used to fix the back adhesive to reduce the risk of sliding of the back adhesive relative to the winding member, thereby realizing the winding of the back adhesive by the winding member.

[0008] In some embodiments, the fixing structure comprises a groove for accommodating the back adhesive. The end of the back adhesive is inserted into the groove to achieve the effect of fixing the back adhesive.

[0009] In some embodiments, the groove penetrates the winding member in a direction perpendicular to the rotation axis of the winding member. The penetrating groove is provided to facilitate the poking of the back adhesive out of the groove, thereby improving the efficiency of taking the back adhesive off the winding member.

[0010] In some embodiments, the dismounting device further comprises a cutting assembly movably arranged on one side of the winding member, and the cutting assembly is used for cutting the back adhesive on the winding member. The back adhesive is cut to facilitate the taking of the back adhesive off the winding member.

The sliding rail is arranged on one side of the winding piece, and the extending direction of the sliding rail is parallel to the rotating axis of the winding piece. The cutter body is slidingly connected to the sliding rail through the sliding block. The cutter body extends towards the winding piece from the sliding rail, and the side of the cutter body facing the winding piece is provided with a blade. The blade is moved synchronously by sliding the cutter body along the sliding rail to cut the back adhesive.

[0012] In some embodiments, the cutter body is slidingly connected to the sliding block, and the cutter body is configured to move relative to the sliding block in a direction perpendicular to the rotating axis of the winding piece under the action of an external force, and the blade is moved synchronously by the cutter body.

[0013] The cutter body is slidingly connected to the sliding block to enable the cutter body to move close to the winding piece, thereby cutting the back adhesive on the winding piece after winding is completed, and the risk of the cutting assembly hindering the rotation of the winding piece during winding of the back adhesive is reduced.

[0014] In some embodiments, the blade can be accommodated in the cutter body. The cutter body is provided with a connecting rod assembly connected to the blade. The connecting rod assembly is used to move the blade under the action of an external force, and the blade is protruded from the cutter body to the outside of the cutter body.

[0015] The blade is arranged to be extended and retracted in the cutter body to achieve the function of accommodating the blade without cutting, thereby reducing the risk of the blade scratching the human body.

[0016] In some embodiments, the dismounting device further comprises a support arranged to rotate relative to the carrier plate. The winding piece is rotatably connected to the support. The support is used to rotate the winding piece relative to the carrier plate and move the winding piece away from the positioning assembly.

The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0032] The application provides a dismounting device, comprising a carrier plate, a positioning assembly and a winding member. The carrier plate is used for carrying electronic products. The positioning assembly is arranged on the carrier plate and is used for positioning the electronic products. The winding member is located on one side of the carrier plate and is used for winding the adhesive on the electronic products.

[0033] In the above embodiment, the electronic products on the carrier plate are fixed by the positioning assembly, and the adhesive on the electronic products is wound by the winding member to remove the adhesive, thereby improving the dismounting efficiency of the adhesive.

[0034] Some embodiments of the application will be described in detail with reference to the drawings. The following embodiments and features of the embodiments can be combined with each other without conflict.

[0035] In some embodiments, referring to Figure 1 The dismounting device 10 comprises a base 20, a carrier plate 11, a positioning assembly 12 and a winding member 13. The carrier plate 11 is arranged on the base 20 and is used for carrying electronic products (not shown). The positioning assembly 12 is arranged on the carrier plate 11. The winding member 13 is arranged on the base 20 and is located on one side of the carrier plate 11. In use, the electronic products are placed on the carrier plate 11, and then the electronic products on the carrier plate 11 are fixed by the positioning assembly 12, thereby improving the fixity of the electronic products relative to handheld fixing. When the electronic products are fixed, one end of the adhesive (not shown) is pulled from the electronic products to the winding member 13, and the adhesive on the electronic products is wound by the winding member 13, thereby removing the adhesive, which improves the dismounting efficiency of the adhesive relative to handheld stretching of the adhesive. After the adhesive on the electronic products is removed, the electronic products are unloaded from the carrier plate 11, and the next electronic products are placed, and the process is repeated in sequence, thereby realizing continuous dismounting of the adhesive.

[0036] Meanwhile, the winding member 13 can be rotated at a specified position to keep the position of the winding member 13 acting on the adhesive unchanged, which can reduce the risk of the adhesive being broken due to overstretching relative to handheld adhesive and reciprocating pulling of the adhesive, thereby improving the stability of dismounting the adhesive.

[0037] In some embodiments, the surface of the carrier plate 11 is parallel to the X-axis direction, and the winding member 13 is located on one side of the carrier plate 11 along the X-axis direction.

[0038] In some embodiments, the X-axis is parallel to the horizontal plane.

[0039] In other embodiments, the X-axis is arranged at an angle to the horizontal plane.

[0040] In some embodiments, the plate surface of the carrier plate 11 is parallel to the plate surface of the battery of the electronic product.

[0041] Further, the rotation axis of the winding member 13 is parallel to the Y-axis direction, the Y-axis is perpendicular to the X-axis, and the Y-axis and the X-axis are both parallel to the horizontal plane, that is, the rotation axis of the winding member 13 is parallel to the plate surface of the carrier plate 11. When the end of the adhesive tape is pulled out on the electronic product and fixed on the winding member 13, the thickness direction of the end of the adhesive tape is perpendicular to the Z-axis, wherein the Z-axis, the Y-axis and the X-axis are all perpendicular to each other, and the Z-axis is parallel to the direction of gravity.

[0042] By parallelizing the rotation axis of the winding member 13 and the Y-axis direction, after the end of the adhesive tape is pulled out on the electronic product on the carrier plate 11 and fixed on the winding member 13, the strip-shaped adhesive tape can be wound on the winding member 13 in a flat state (even if the thickness direction of the adhesive tape is perpendicular to the rotation axis of the winding member 13), thereby facilitating the winding of the winding member 13 on the adhesive tape. Compared with the setting mode in which the rotation axis of the winding member 13 is parallel to the Z-axis direction (that is, the thickness direction of the adhesive tape is perpendicular to the Y-axis), the risk of creasing of the adhesive tape during winding can be reduced (at this time, the thickness direction of the adhesive tape is parallel to the Y-axis).

[0043] In other embodiments, the rotation axis of the winding member 13 is parallel to the Z-axis.

[0044] In some embodiments, referring to Figure 2 , the winding member 13 comprises a winding surface 131, and the winding member 13 is a cylindrical member, and the winding surface 131 is an arc surface. Compared with the setting mode in which the winding member 13 has an edge, the setting mode is advantageous in reducing the risk of stress concentration and fracture of the adhesive tape on the winding member 13.

[0045] In other embodiments, the winding member 13 is a columnar member with a polygonal cross section.

[0046] In some embodiments, referring to Figure 2 , the winding surface 131 is provided with a fixing structure 132, and the end of the adhesive tape is fixed by the fixing structure 132, thereby improving the fixing between the winding member 13 and the adhesive tape, so as to reduce the risk of sliding of the adhesive tape relative to the winding member 13 when the winding member 13 just starts to wind the adhesive tape, and to facilitate the winding of the winding member 13 on the adhesive tape.

[0047] In some embodiments, referring to Figure 3 , the fixing structure 132 is a groove 133, and after one end of the adhesive tape is pulled out on the electronic product, the adhesive tape is inserted into the groove 133, so as to fix the adhesive tape by increasing the static friction, thereby reducing the risk of relative sliding between the adhesive tape and the winding member 13.

[0048] In other embodiments, the fixing structure 132 is a plurality of protrusions or spikes (not shown) arranged on the winding surface 131, so that the winding piece 13 is arranged in a club shape, and the protrusions or spikes are in contact with the back adhesive, thereby increasing the friction between the back adhesive and the winding surface 131, and achieving the effect of avoiding relative sliding between the back adhesive and the winding piece 13.

[0049] In some embodiments, one end of the winding piece 13 is provided with a driving assembly 134, which is a rotating handle. In use, the rotating handle is operated to drive the winding piece 13 to rotate, thereby achieving the function of winding the back adhesive by the winding piece 13.

[0050] In other embodiments, the driving assembly 134 is a motor, and one end of the winding piece 13 is connected to the output end of the motor.

[0051] In some embodiments, referring to Figure 1 and Figure 2 , the dismounting device 10 further comprises a bracket 15, which is rotatably connected to the base 20, and the bracket 15 is provided with a lug 151, and the winding piece 13 is rotatably connected to the bracket 15 through the lug 151. When the winding is completed, the bracket 15 is operated to rotate relative to the base 20, so that the bracket 15 drives the winding piece 13 to move away from the carrier plate 11, thereby reducing the hindrance of the carrier plate 11 or the electronic product on the carrier plate 11 to the winding piece 13, and achieving the effect of facilitating the dismounting of the back adhesive on the winding piece 13.

[0052] It can be understood that when the electronic product needs to be placed on the carrier plate 11, the bracket 15 drives the winding piece 13 to move away from the carrier plate 11, which can also reduce the risk of hindering the carrier plate 11 and the positioning assembly 12 by the winding piece 13, thereby facilitating the fixation of the electronic product.

[0053] In some embodiments, the rotation axis of the bracket 15 is parallel to the X-axis or the Y-axis.

[0054] In some embodiments, the driving assembly 134 is arranged on the bracket 15.

[0055] In some embodiments, referring to Figure 2 , the base 20 is further provided with a first limiting block 16, which supports and positions the bracket 15, so that the winding piece 13 maintains a certain distance from the base 20, thereby facilitating the winding of the back adhesive by the winding piece 13.

[0056] In some embodiments, referring to Figure 1 and Figure 2The base 20 is further provided with a first lock 17. When the first limiting block 16 supports the support 15, the support 15 is locked by the first lock 17, so as to reduce the risk of relative movement between the support 15 and the first limiting block 16, and the relative position between the winding piece 13 and the base 20 remains unchanged, thereby improving the stability of winding of the winding piece 13.

[0057] In some embodiments, referring to Figure 1 The dismounting device 10 further comprises a cutting assembly 14 arranged on one side of the winding piece 13. After the winding piece 13 completes winding of the back adhesive, the back adhesive is cut by the cutting assembly 14, and the back adhesive is unwound again relative to the winding piece 13, which helps to improve the efficiency of separation of the back adhesive from the winding piece 13, so as to facilitate the winding piece 13 to wind the back adhesive of the next electronic product.

[0058] In some embodiments, referring to Figure 4 The cutting assembly 14 comprises a sliding rail 141, a sliding block 142 and a cutter body 143. The sliding rail 141 is arranged on one side of the winding piece 13, and the cutter body 143 is slidably connected to the sliding rail 141 through the sliding block 142. The cutter body 143 extends upwards from the sliding rail 141 towards the winding piece 13, so as to facilitate the cutter body 143 to approach the winding piece 13. The side of the cutter body 143 facing the winding piece 13 is provided with a blade 144. The extension direction of the sliding rail 141 is parallel to the rotation axis of the winding piece 13. After the winding piece 13 completes winding of the back adhesive, the cutter body 143 is operated to move along the sliding rail 141 and synchronously drive the blade 144 to cut across the back adhesive on the winding piece 13, thereby achieving the effect of cutting the back adhesive.

[0059] In some embodiments, the sliding rail 141 is arranged on the side of the winding piece 13 away from the carrier plate 11, so as to reduce the risk of hindering the winding piece 13 from winding the back adhesive.

[0060] In some embodiments, the cutter body 143 is slidably connected to the sliding block 142. When cutting is not needed, the cutter body 143 is slid relative to the sliding block 142 and away from the winding piece 13, so as to reduce the hindrance of the cutter body 143 to the winding piece 13 or the support 15, thereby facilitating the support 15 to drive the winding piece 13 to rotate or fix one end of the back adhesive to the winding piece 13.

[0061] In some embodiments, referring to Figure 1 and Figure 4 One end of the sliding rail 141 extends to the outside of the winding piece 13 along the Y-axis direction, so that the sliding block 142 can drive the cutter body 143 to move away from the upper side of the winding piece 13 when cutting is not needed.

[0062] In some embodiments, the cutter body 143 is also rotatably connected with the sliding block 142, and the cutter body 143 is rotatable relative to the sliding block 142 along a direction parallel to the Z-axis as the axis, so as to realize the function of moving the cutter body 143 away from the winding element 13.

[0063] In some embodiments, when the cutter body 143 extends above the winding element 13 along the Z-axis direction, the cutter body 143 is slidably connected with the sliding block 142 and is movable relative to the sliding block 142 along the Z-axis direction, so as to realize the function of moving the cutter body 143 close to the winding element 13.

[0064] In other embodiments, when the cutter body 143 is located on the side of the winding element 13 in other directions, the cutter body 143 is slidably connected with the sliding block 142 and is movable relative to the sliding block 142 close to the winding element 13.

[0065] In some embodiments, referring to Figure 4 , a first spring 145 is arranged between the cutter body 143 and the sliding block 142, and when the cutter body 143 is moved relative to the sliding block 142 by an external force and close to the winding element 13, the cutter body 143 compresses the first spring 145. After the adhesive cutting is completed, the external force on the cutter body 143 is removed, and the first spring 145 pushes the cutter body 143 to reset, which helps to improve the automation function of the cutting assembly 14.

[0066] In some embodiments, referring to Figure 4 and Figure 5 , the blade 144 is arranged on the cutter body 143 in an extendable and retractable manner, so that when cutting is not needed, the blade 144 can be accommodated in the cutter body 143, so as to reduce the risk of the blade 144 scratching the human body and improve the safety of the cutting assembly 14.

[0067] For example, the cutter body 143 is provided with a driving structure (not identified), and when the blade 144 needs to be extended, the driving structure on the cutter body 143 is operated, the driving structure drives the blade 144 to move, so that the blade 144 is extended in the cutter body 143.

[0068] In some embodiments, referring to Figure 5 , the driving structure includes a button 148 and a connecting rod assembly 147, two ends of the connecting rod assembly 147 are respectively in contact with the button 148 and the blade 144, and the middle part of the connecting rod assembly 147 is rotatably connected with the cutter body 143. By pressing the button 148, the connecting rod assembly 147 is rotated, and the connecting rod assembly 147 drives the blade 144 to move through the lever principle, so as to realize the function of driving the blade 144 to extend out of the cutter body 143.

[0069] Further, referring to Figure 5The second spring 146 is arranged on the cutter body 143. When the connecting rod assembly 147 drives the cutter blade 144 to extend out of the cutter body 143, the second spring 146 is in a compressed state. When the action force of the button 148 is removed, the second spring 146 is elastically reset and drives the cutter blade 144, the connecting rod assembly 147 and the button 148 to reset, so as to realize the function of automatic contraction of the cutter blade 144.

[0070] It can be understood that the two ends of the second spring 146 are connected with the cutter blade 144 and the cutter body 143 respectively.

[0071] In other embodiments, the cutting assembly 14 is further provided with a linkage structure (not shown) arranged on the cutter body 143 and connected with the cutter blade 144. When the cutter body 143 moves relative to the slider 142 to a specified distance, a component on the slider 142 acts on the linkage structure, and the linkage structure drives the cutter blade 144 to extend out of the cutter body 143, so as to realize the function that the cutter body 143 approaches the winding piece 13 while the cutter blade 144 extends out of the cutter body 143. The convenience of operating the cutting assembly 14 is improved.

[0072] In other embodiments, the cutting assembly 14 further comprises a rotating arm (not shown) and a circular cutter blade. One end of the rotating arm is connected with the base 20, and the circular cutter blade is rotationally connected with the other end of the rotating arm. When cutting the back adhesive, the rotating arm is operated to rotate, so as to drive the circular cutter blade in a rotating state to approach the winding piece 13 and cut the back adhesive by rotating, so as to also realize the function of the cutting assembly 14 to cut the back adhesive.

[0073] It can be understood that when the fixing structure 132 is the groove 133, the groove 133 is also used to accommodate the cutter blade 144 of the cutting assembly 14, so as to reduce the risk that the cutter blade 144 scratches the winding piece 13.

[0074] In some embodiments, please refer to Figure 3 The groove 133 is a through groove. The cutter blade 144 extends into the groove 133 and cuts the back adhesive wound on the winding piece 13 through the groove 133, so as to realize the function of cutting and pushing out the back adhesive in the groove 133, and achieve the effect of analogy.

[0075] In some embodiments, the cutting assembly 14 further comprises a driver (not shown). One driver drives the slider 142 to reciprocate, and the other driver drives the cutter body 143 to move close to or away from the winding piece 13, so as to realize the function of automatic cutting of the back adhesive.

[0076] In some embodiments, please refer to Figure 1 and Figure 6The positioning assembly 12 comprises a plurality of positioning blocks 121 arranged in a ring shape. When the electronic product is placed on the carrier plate 11, the plurality of positioning blocks 121 surround the electronic product to position the electronic product in the horizontal direction.

[0077] Further, referring to Figure 1 and Figure 6 , the positioning assembly 12 further comprises a cover plate 122 rotationally connected to the carrier plate 11. When the electronic product is placed on the carrier plate 11, the cover plate 122 is rotated to cover the electronic product, thereby positioning the electronic product in the vertical direction to reduce the risk of movement of the electronic product relative to the carrier plate 11 and improve the stability of the adhesive disassembly.

[0078] In some embodiments, referring to Figure 1 and Figure 6 , the base 20 is further provided with a second limiting block 18. When the cover plate 122 covers the electronic product, the second limiting block 18 limits the cover plate 122 to reduce the risk of damage to the electronic product and the battery caused by the cover plate 122.

[0079] In some embodiments, referring to Figure 1 and Figure 6 , the base 20 is further provided with a second locking buckle 19. When the cover plate 122 covers the electronic product, the second locking buckle 19 locks the cover plate 122 on the second limiting block 18 to reduce the risk of movement of the cover plate 122 relative to the carrier plate 11 and improve the stability of the cover plate 122 covering the electronic product.

[0080] It can be understood that when the cover plate 122 covers the electronic product, the cover plate 122 does not press the electronic product towards the carrier plate 11, so that the adhesive can be pulled out from between the electronic product and the battery under the winding effect of the winding member 13.

[0081] In some embodiments, the connection between the cover plate 122 and the base 20 is located on the side of the carrier plate 11 away from the winding member 13 to reduce the risk of obstruction of the winding member 13 by the cover plate 122.

[0082] In other embodiments, the cover plate 122 can also be slidingly connected to the base 20, and the cover plate 122 can also be slid to the top of the electronic product to cover the electronic product.

[0083] In some embodiments, the electronic product is a mobile phone, a tablet computer, or other electronic device with a battery.

[0084] In addition, those skilled in the art should understand that the above-mentioned embodiments are only used to explain the present application, and are not used as limitation to the present application, and as long as the changes and variations of the above-mentioned embodiments are within the spirit of the present application, they fall within the scope of the present application.
