[0030] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0031] See also Figures 1 to 4 , Figure 1 is a schematic diagram of the structure of a sheet base film peeling device provided in an embodiment of the present application, Figure 2 yes Figure 1 The schematic diagram of the stripping assembly shown in FIG. Figure 3 yes Figure 2 The enlarged structural diagram of the A area is shown. Figure 4 yes Figure 1 The schematic diagram of the relative position structure of the stripping component and the sheet material is shown.

[0032] The sheet base film stripping device 100 includes a stripping guide 11, a stripping assembly 12, an unwinding assembly 13 and a traction assembly 14. The stripping guide 11 includes an inlet end A and an outlet end B. The stripping assembly 12 is arranged at the outlet end B of the stripping guide 11. The stripping assembly 12 has a gap 120. The unwinding assembly 13 is used to install the tape roll 20. The tape roll 20 is used to release the tape 21, and the tape 21 is used to carry and transmit the sheet 30. The sheet 30 includes a base film 31 and a material 32 arranged on the base film. The traction assembly 14 is used to stretch the tape 21 so that the sheet 30 carried by the tape 21 passes through the inlet end A, the outlet end B and the gap 120 in sequence, and the base film 31 and the material 32 are separated at the gap 120. Among them, the stripping guide 11 plays a supporting role, supporting the tape 21 and the sheet 30 attached to the tape 21.

[0033] Compared with manual peeling of the bottom film, the bottom film peeling device 100 uses the adhesive force of the adhesive tape 21 to peel off the bottom film 31 of the sheet 30, which significantly improves the peeling speed and efficiency of the bottom film 31. In addition, by continuously pulling the adhesive tape 21, the bottom film 31 can be peeled off continuously and for a long time, which is low in cost, fast in speed and high in efficiency. It can be understood that the adhesive tape 21 not only has the function of pulling the sheet 30 for transmission, but also has the function of taking away the bottom film 31.

[0034] In one embodiment, the adhesive tape 21 is a disposable adhesive tape, that is, an adhesive tape that is discarded after use.

[0035] In one embodiment, the adhesive tape 21 is a non-disposable adhesive tape, that is, an adhesive tape that can be used again after peeling off the base film 31, and the adhesiveness of the adhesive tape is not significantly reduced.

[0036] In this embodiment, the stripping assembly 12 includes a stripping plate 121 and a guide plate 122, and the stripping plate 121 is located on a side of the guide plate 122 close to the stripping guide rail. The stripping plate 121 cooperates with the guide plate 122 to form a gap 120. It should be noted that the way in which the stripping assembly 12 forms the gap 120 is not limited to the above-mentioned way, and is specifically designed according to needs; for example, the side of the stripping plate is provided with an opening, and the opening forms the gap 120.

[0037] In one embodiment, the width of the slit 120 is greater than the thickness of the bottom film 31 and less than the thickness of the material 32, so that the bottom film 31 can pass through the slit 120 along with the tape 21, and the material 32 cannot pass through the slit 120, so that the bottom film 31 and the material 32 of the sheet 30 can be peeled off, while reducing the probability of material jamming. It should be noted that the width of the slit 120 is greater than the sum of the thickness of the tape 21 and the thickness of the bottom film 31, so that the bottom film 31 can pass through the slit 120 along with the tape 21.

[0038] In one embodiment, the stripping plate 121 and the guide plate 122 are spaced apart; the spacing between the stripping plate 121 and the guide plate 122 is the same at all locations, so that the width of the slit 120 is the same at all locations along the length direction of the slit 120. It should be noted that the length direction of the slit 120 is perpendicular to the transmission direction of the tape 21, and the width of the slit 120 refers to the size of the slit 120 along the transmission direction of the tape 21.

[0039] In one embodiment, the stripping plate 121 and the guide plate 122 are spaced apart from each other; the spacing between the stripping plate 121 and the guide plate 122 is different, and the width of the gap 120 can be gradually increased from one end to the other end, or can be gradually decreased, or can be gradually increased and then gradually decreased, etc., so that the stripping plate 121 and the guide plate 122 can cooperate to separate the base film 31 and the material 32.

[0040] In one embodiment, the top of the stripping plate 121 is located above the guide plate 122. By making the top of the stripping plate 121 located above the guide plate 122, that is, the top of the stripping plate 121 is higher than the guide plate 122, the angle between the bottom film 31 attached to the tape 21 and the material 32 at the gap 120 of the sheet 30 is less than 90 degrees, which promotes the separation of the material 32 from the bottom film 31.

[0041] In one embodiment, the stripping plate 121 is tilted relative to the stripping guide rail 11, and the top of the stripping plate 121 cooperates with the guide plate 122 to form a gap 120. The stripping plate 121 is tilted downward relative to the stripping guide rail 11; specifically, the distance between the top of the stripping plate 121 and the stripping guide rail 11 is greater than the distance between the bottom of the stripping plate 121 and the stripping guide rail 11.

[0042] Optionally, when the stripping plate 121 is tilted relative to the stripping guide rail 11, the guide plate 122 can be arranged parallel to the stripping guide rail 11. When the stripping guide rail 11 is arranged parallel to the ground, the guide plate 122 is arranged parallel to the ground, and a conveyor belt is arranged on the guide plate 122 or a conveyor belt is used as the guide plate 122 to convey the stripped material 32 away.

[0043] Optionally, when the stripping plate 121 is tilted relative to the stripping guide rail 11, the guide plate 122 can be tilted relative to the stripping guide rail 11, and the top of the guide plate 122 is close to the top of the stripping plate 121, and the bottom of the guide plate 122 is away from the bottom of the stripping plate 121. By tilting the guide plate 122, the gravity of the material 32 is utilized to promote the separation of the material 32 from the bottom film 31. The material 32 can be transported along the guide plate 122 by itself under the action of gravity; or a conveyor belt or a conveyor belt as the guide plate 122 can be provided on the guide plate 122 to transport the material 32. Exemplarily, the distance between the top of the stripping plate 121 and the stripping guide rail 11 is greater than the distance between the bottom of the stripping plate 121 and the stripping guide rail 11; the distance between the top of the guide plate 122 and the stripping guide rail 11 is less than the distance between the bottom of the guide plate 122 and the stripping guide rail 11. By setting the material guide plate 122 at an angle, after the material 32 is mostly separated from the bottom film 31, it can be further separated from the bottom film 31 completely by gravity, and can be transported to the next level.

[0044] In one embodiment, the sheet material 30 further includes a scoring ring 33. The scoring ring 33 is disposed on the surface of the base film 31, and the scoring ring 33 is disposed around the material 32. The stripping assembly 12 further includes a guide plate 123, and the guide plate 123 is disposed on a side of the guide plate 122 away from the stripping plate 121. The guide plate 123 is spaced apart from the stripping plate 121, so as to separate the scoring ring 33 from the material 32 while stripping the base film 31.

[0045] Optionally, the cutting ring 33 is a steel ring. The steel ring has high structural rigidity. The rigidity of the cutting ring 33 is much greater than the rigidity of the base film 31 and / or the material 32, so as to achieve separation of the material 32, the base film 31 and the cutting ring 33.

[0046] Optionally, the top of the guide plate 122 is higher than the guide plate 123 , that is, the top of the guide plate 122 is located above the guide plate 123 , and the gravity of the cutting circle 33 is used to promote the separation of the cutting circle 33 and the material 32 .

[0047] Optionally, the guide plate 122 is tilted relative to the stripping guide rail 11 (the specific arrangement of the guide plate 122 can be referred to the above description), and the guide plate 123 is tilted relative to the stripping guide rail 11, and the distance between the bottom end of the guide plate 123 and the stripping guide rail 11 is greater than the distance between the top end of the guide plate 123 and the stripping guide rail 11. By tilting the guide plate 123, after the cutting circle 33 is mostly separated from the bottom film 31, it can be further separated from the bottom film 31 by gravity, and can be transported to the next level.

[0048] The distance between the top of the guide plate 122 and the top of the guide plate 123 is greater than the cross-sectional dimension of the material 32, so that the material 32 can be conveyed through the gap between the guide plate 122 and the guide plate 123; the distance between the top of the guide plate 122 and the top of the guide plate 123 is less than the cross-sectional dimension of the cutting circle 33, so that the cutting circle 33 cannot pass through the gap between the guide plate 122 and the guide plate 123, so as to separate the cutting circle 33 from the material 32. It should be noted that the cross-sectional dimension in the present application refers to the dimension of the cross section perpendicular to the material conveying direction; for example: in some embodiments, the cross section of the material 32 perpendicular to its conveying direction includes thickness and width, so the spacing parameter needs to satisfy the requirement of being greater than thickness and width. Since the width is much greater than the material width, the spacing parameter is actually greater than its thickness. Similarly, the spacing of the gap 120 is between the thickness of the material 32 and the thickness of the superposition of the bottom film 31 and the tape 21. The cross-sectional dimension of the cutting circle 33 mainly refers to its length dimension.

[0049] By setting the guide plate 122 and the guide plate 123 to the above-mentioned inclined state, the material 32 and the cutting circle 33 that cannot pass through the gap 120 cannot be conveyed through the gap between the guide plate 123 and the material guide plate 122 due to the effect of the distance between the guide plate 123 and the material guide plate 122. The peeled cutting circle 33 is conveyed along the guide plate 123 by its own gravity or conveyed by a conveyor belt (a conveyor belt is provided on the surface of the guide plate 123 or the conveyor belt serves as the guide plate 123). The peeled material 32 is conveyed along the guide plate 122 by its own gravity or conveyed by a conveyor belt (a conveyor belt is provided on the surface of the guide plate 122 or the conveyor belt serves as the guide plate 122).

[0050] Optionally, the guide plate 122 is inclined relative to the stripping guide rail 11, and the guide plate 123 can be arranged parallel to the stripping guide rail 11. When the stripping guide rail 11 is arranged parallel to the ground, the guide plate 123 is arranged parallel to the ground, and a conveyor belt is arranged on the guide plate 123 or the conveyor belt serves as the guide plate 123 to convey the stripped cut circle 33 away.

[0051] It should be noted that the guide plate 123 is an optional structure, and whether to set the guide plate 123 is specifically designed according to needs. For example, when the sheet 30 does not include the cutting circle 33, the guide plate 123 may not be set.

[0052] In one embodiment, the traction assembly 14 includes a receiving shaft 141 and a driving member 142. The receiving shaft 141 is used to wind the stretched tape 21. The driving member 142 is connected to the receiving shaft 141, and the receiving shaft 141 is used to drive the receiving shaft 141 to rotate so that the tape 21 is wound around the receiving shaft 141. The traction assembly 14 is designed as above, the method of stretching the tape 21 is simple, and the tape 21 can be wound, which is conducive to keeping the environment clean.

[0053] Optionally, the driving member 142 is a motor to realize automatic stripping of the sheet material 30. For example, a servo motor or other motor. The motor drives the material receiving shaft 141 to rotate, which is conducive to realizing continuous and long-term stripping.

[0054] In one embodiment, the traction assembly 14 includes a receiving shaft 141, and the receiving shaft 141 is used to wind the stretch tape 21. The operator manually rotates the receiving shaft 141 to stretch the tape 21.

[0055] It should be noted that the traction component 14 includes but is not limited to the implementation methods described above, and can realize the stretching tape 21, and the tape 21 drives the sheet material 30 to pass through the stripping component 12. The setting method of the traction component 14 can be designed according to specific needs.

[0056] In one embodiment, the unwinding assembly 13 includes a support seat 131, a bearing 132, and a sliding shaft 133. The support seat 131 includes a bottom wall and two side walls arranged on the bottom wall, and the two side walls are spaced apart. The bearing 132 is fixed to the end surface of the side wall of the support seat 131. Both ends of the sliding shaft 133 are fixed to the bearing 132. The sliding shaft 133 is used to assemble the tape roll 20; in other words, the tape roll 20 is sleeved on the sliding shaft 133.

[0057] In one embodiment, the sheet base film stripping device 100 further includes a workbench 15 and a bracket 16. The unwinding assembly 13 is fixed to the workbench 15; specifically, the support seat 131 of the unwinding assembly 13 is fixed to the workbench 15. The stripping guide rail 11 is fixed to the workbench 15 through the bracket 16. The stripping assembly 12 is fixed to the bracket 16 and is located at the discharge end B of the stripping guide rail 11.

[0058] Optionally, the workbench 15 includes a table 151, support legs 152 supporting the table 151, and a support beam 153 connecting two adjacent support legs 152. The bracket 16 and the unwinding assembly 13 are fixed to the table 151. The traction assembly 14 is fixed to the support beam 153, that is, the traction assembly 14 is arranged on the lower side of the stripping guide rail 11, which is conducive to reducing the floor space occupied by the sheet base film stripping device 100.

[0059] See also Figure 5 and Figure 6 , Figure 5 is a schematic structural diagram of a sheet base film peeling mechanism provided in an embodiment of the present application, Figure 6 It is a schematic diagram of the relative position structure of the sheet and the gap.

[0060] The embodiment of the present application also provides a sheet base film peeling mechanism, which includes a sheet base film peeling device 100 and a discharging device 200. The specific structural arrangement of the sheet base film peeling device 100 can be referred to the above introduction and will not be repeated. The discharging device 200 is used to attach the sheet 30 to the surface of the tape 21.

[0061] It should be noted that the unloading device 200 can pick up the sheet 30 and place the sheet 30 on the surface of the portion of the tape 21 located on the stripping guide 11. The specific structure of the unloading device 200 is designed as required. In some other embodiments, the sheet 30 can also be placed on the surface of the portion of the tape 21 located on the stripping guide 11 manually.

[0062] In one embodiment, the profile of the sheet 30 includes edges and corners; illustratively, the profile of the sheet 30 is a rhombus. The material discharging device 200 is used to place the edges and corners of the sheet 30 toward the conveying direction of the tape, so that the portion where the sheet 30 first enters the gap 120 is the edge and corner, and the bottom film 31 is easy to be angled, so as to keep the stripping smooth, reduce the probability of material jamming, and help to speed up the stripping speed.

[0063] Optionally, the edge of the sheet 30 placed toward the transmission direction of the tape 21 is defined as the first edge. The discharge device 200 is used to place the sheet 30 so that the angle α formed by the edge forming the first angle and the width direction of the tape 21 is greater than or equal to 30 degrees and less than or equal to 150 degrees. The bottom film 31 is easy to form an angle, which keeps the stripping smooth, reduces the probability of material jamming, and helps to speed up the stripping speed.

[0064] See also Figure 7 , Figure 7 It is a schematic flow chart of the method for peeling off the base film provided in an embodiment of the present application.

[0065] The method for peeling the bottom film provided in the embodiment of the present application can use the sheet bottom film peeling mechanism introduced in the above embodiment to peel the bottom film. The method for peeling the bottom film specifically includes:

[0066] Step S01: Install the tape roll 20 on the unwinding assembly 13, and make the tape 21 of the tape roll 20 pass through the feeding end A of the stripping guide rail 11, the discharging end B of the stripping guide rail 11, and the gap 120 in sequence, and the end of the tape 21 is fixed to the traction assembly 14.

[0067] Step S02 : using the unloading device 200 to attach a plurality of sheets 30 to the surface of the adhesive tape 21 .

[0068] Specifically, the unloading device 200 places a plurality of sheets 30 on the surface of a portion of the adhesive tape 21 located on the stripping guide track 11 .

[0069] In one embodiment, the profile of the sheet 30 includes edges and corners; illustratively, the profile of the sheet 30 is a rhombus. The unloading device 200 is used to place the sheet 30 with the edges and corners facing the conveying direction of the tape, and the angle formed by the edge of the edges and the width direction of the tape 21 is greater than or equal to 30 degrees and less than or equal to 150 degrees, so that the bottom film 31 is easy to be angled, which keeps the stripping smooth, reduces the probability of material jamming, and is conducive to accelerating the stripping speed.

[0070] Step S03 : the traction component 14 stretches the tape 21 so that the sheet material 30 carried by the tape 21 passes through the feed end A, the discharge end B and the gap 120 in sequence, and the base film 31 and the material 32 are separated at the gap 120 .

[0071] In one embodiment, the width of the gap 120 is greater than the thickness of the base film 31 and less than the thickness of the material 32, so that the base film 31 can pass through the gap 120 along with the tape 21, and the material 32 cannot pass through the gap 120, thereby achieving the peeling of the base film 31 and the material 32 of the sheet 30 and reducing the probability of material jamming.

[0072] In one embodiment, the sheet 30 further includes a scoring ring 33, which is disposed on the surface of the bottom film 31 and surrounds the material 32. The stripping assembly 12 further includes a guide plate 123, which is disposed on a side of the guide plate 122 away from the stripping plate 121; the distance between the guide plate 123 and the guide plate 122 is greater than the size of the material 32 and smaller than the size of the scoring ring 33, so that the material 32 can be transferred through the gap between the guide plate 122 and the guide plate 123, and the scoring ring 33 cannot pass through the gap between the guide plate 122 and the guide plate 123, so as to achieve the separation of the scoring ring 33 and the material 32, that is, to achieve the synchronous separation of the material 32, the bottom film 31, and the scoring ring 33 of the sheet 30.

[0073] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application.
