[0027] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of the sheet material bottom film peeling device provided in the embodiments of this application. Figure 2 yes Figure 1The diagram shown illustrates the structure of the material stripping assembly. Figure 3 yes Figure 2 The diagram shows an enlarged view of region A. Figure 4 yes Figure 1 The diagram shows the relative positions of the stripping assembly and the sheet material.

[0029] The sheet material bottom film peeling device 100 includes a peeling guide rail 11, a peeling assembly 12, an unwinding assembly 13, and a traction assembly 14. The peeling guide rail 11 includes an inlet end A and an outlet end B. The peeling assembly 12 is located at the outlet end B of the peeling guide rail 11. The peeling assembly 12 has a slit 120. The unwinding assembly 13 is used to mount the tape roll 20. The tape roll 20 is used to release the tape 21, which carries and transports the sheet material 30. The sheet material 30 includes a bottom film 31 and a material 32 disposed on the bottom film. The traction assembly 14 is used to stretch the tape 21 so that the sheet material 30 carried by the tape 21 passes sequentially through the inlet end A, the outlet end B, and the slit 120, achieving separation of the bottom film 31 and the material 32 at the slit 120. The peeling guide rail 11 provides support, supporting the tape 21 and the sheet material 30 attached to it.

[0030] Compared to manual peeling of the bottom film, the sheet bottom film peeling device 100 utilizes the adhesive force of the tape 21 to peel the bottom film 31 from the sheet 30, significantly improving the peeling speed and efficiency. Furthermore, by continuously pulling the tape 21, continuous and prolonged peeling of the bottom film 31 is achieved, resulting in low cost, high speed, and high efficiency. It can be understood that the tape 21, in addition to its function of transporting the sheet 30, also serves to remove the bottom film 31.

[0031] In one embodiment, tape 21 is disposable tape, that is, tape that is discarded after use.

[0032] In one embodiment, the tape 21 is a non-disposable tape, that is, a tape that can be reused after the peeling backing film 31 has been used, and the tape's adhesiveness is not significantly reduced.

[0033] In this embodiment, the stripping assembly 12 includes a stripping plate 121 and a guide plate 122, with the stripping plate 121 located on the side of the guide plate 122 near the stripping guide rail. The stripping plate 121 and the guide plate 122 cooperate to form a gap 120. It should be noted that the way the stripping assembly 12 forms the gap 120 is not limited to the above-described manner, and can be designed according to specific needs; for example, the side of the stripping plate may have an opening, which forms the gap 120.

[0034] 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 with the tape 21, while 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 jamming. It should be noted that the width of the gap 120 is greater than the sum of the thickness of the tape 21 and the thickness of the base film 31, just enough to allow the base film 31 to pass through the gap 120 with the tape 21.

[0035] In one embodiment, the stripper plate 121 and the guide plate 122 are spaced apart; the spacing between the stripper plate 121 and the guide plate 122 is the same at all points, so that the width of the gap 120 is the same at all points along the length direction of the gap 120. It should be noted that the length direction of the gap 120 is perpendicular to the conveying direction of the tape 21, and the width of the gap 120 refers to the size of the gap 120 along the conveying direction of the tape 21.

[0036] In one embodiment, the peeling plate 121 and the guide plate 122 are spaced apart; the spacing between the peeling plate 121 and the guide plate 122 is different at various points. From one end of the gap 120 to the other end, the width of the gap 120 can gradually increase, gradually decrease, or gradually increase and then gradually decrease, etc., so that the peeling plate 121 and the guide plate 122 can cooperate to separate the bottom film 31 and the material 32.

[0037] In one embodiment, the top of the peeling plate 121 is located above the guide plate 122. By positioning the top of the peeling plate 121 above the guide plate 122, i.e., with the top of the peeling plate 121 higher than the guide plate 122, the angle between the sheet material 30 and the bottom film 31 attached to the adhesive tape 21 at the gap 120 is less than 90 degrees, thus promoting the separation between the sheet material 32 and the bottom film 31.

[0038] In one embodiment, the stripping plate 121 is inclined relative to the stripping guide rail 11, and the top end of the stripping plate 121 cooperates with the guide plate 122 to form a gap 120. The stripping plate 121 is inclined downward relative to the stripping guide rail 11; specifically, the distance between the top end of the stripping plate 121 and the stripping guide rail 11 is greater than the distance between the bottom end of the stripping plate 121 and the stripping guide rail 11.

[0039] Optionally, when the stripping plate 121 is inclined 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 the guide plate 122 is equipped with a conveyor belt or a conveyor belt as the guide plate 122 to convey the stripped material 32 away.

[0040] Optionally, when the peeling plate 121 is inclined relative to the peeling guide rail 11, the guide plate 122 can also be inclined relative to the peeling guide rail 11, with the top end of the guide plate 122 close to the top end of the peeling plate 121 and the bottom end of the guide plate 122 far from the bottom end of the peeling plate 121. By inclining the guide plate 122, the separation of the material 32 from the bottom film 31 is promoted by the gravity of the material 32. The material 32 can be conveyed along the guide plate 122 by gravity; alternatively, a conveyor belt can be provided on the guide plate 122 or a conveyor belt can be used as the guide plate 122 to convey the material 32. For example, the distance between the top end of the peeling plate 121 and the peeling guide rail 11 is greater than the distance between the bottom end of the peeling plate 121 and the peeling guide rail 11; the distance between the top end of the guide plate 122 and the peeling guide rail 11 is less than the distance between the bottom end of the guide plate 122 and the peeling guide rail 11. By tilting the guide plate 122, the material 32 can be completely separated from the bottom film 31 by gravity after most of it has separated, and can be conveyed to the next level.

[0041] In one embodiment, the sheet material 30 further includes a slicing ring 33. The slicing ring 33 is disposed on the surface of the base film 31 and surrounds the material 32. The peeling assembly 12 also includes a guide plate 123, which is disposed on the side of the guide plate 122 away from the peeling plate 121. The guide plate 123 and the peeling plate 121 are spaced apart to separate the slicing ring 33 from the material 32 while peeling off the base film 31.

[0042] Optionally, the dicing ring 33 is a steel ring. The steel ring has very high structural rigidity. By utilizing the fact that the rigidity of the dicing ring 33 is much greater than that of the bottom film 31 and / or the material 32, the separation of the material 32, the bottom film 31, and the dicing ring 33 can be achieved.

[0043] 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 dicing ring 33 is used to promote the separation of the dicing ring 33 from the material 32.

[0044] Optionally, the guide plate 122 is inclined relative to the stripping guide rail 11 (the specific arrangement of the guide plate 122 can be found in the above description), and the guide plate 123 is also inclined relative to the stripping guide rail 11. 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 inclining the guide plate 123, after the dicing ring 33 has mostly detached from the bottom film 31, it can further detach completely from the bottom film 31 by gravity, and can be conveyed to the next stage.

[0045] 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 dicing ring 33, so that the dicing ring 33 cannot pass through the gap between the guide plate 122 and the guide plate 123, thereby separating the dicing ring 33 from the material 32. It should be noted that the cross-sectional dimension in this 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 be greater than the thickness and width. Since the width is much greater than the width of the material, the spacing parameter only needs to be greater than its thickness. Similarly, the spacing of the gap 120 is between the thickness of the material 32 and the thickness of the bottom film 31 and the tape 21 superimposed. The cross-sectional dimension of the dicing ring 33 mainly refers to its length dimension.

[0046] By setting the guide plate 122 and guide plate 123 to the above-mentioned inclined state, the material 32 and the dicing ring 33 that cannot pass through the gap 120 are affected by the distance between the guide plate 123 and the guide plate 122. The dicing ring 33 cannot be conveyed through the gap between the guide plate 123 and the guide plate 122. The peeled dicing ring 33 is conveyed by itself along the guide plate 123 by its own gravity or by the conveyor belt (the surface of the guide plate 123 is provided with a conveyor belt or the conveyor belt is used as the guide plate 123). The peeled material 32 is conveyed by itself along the guide plate 122 by its own gravity or by the conveyor belt (the surface of the guide plate 122 is provided with a conveyor belt or the conveyor belt is used as the guide plate 122).

[0047] 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 the guide plate 123 is provided with a conveyor belt or a conveyor belt as the guide plate 123 to convey the stripped dicing ring 33 away.

[0048] It should be noted that the guide plate 123 is an optional structure, and whether or not to install the guide plate 123 depends on the specific design requirements. For example, when the sheet material 30 does not include the dicing ring 33, the guide plate 123 may not be required.

[0049] In one embodiment, the traction assembly 14 includes a take-up shaft 141 and a drive member 142. The take-up shaft 141 is used to wind the stretch tape 21. The drive member 142 is connected to the take-up shaft 141 and is used to drive the take-up shaft 141 to rotate, so that the tape 21 is wound around the take-up shaft 141. With the above design, the traction assembly 14 simplifies the way the tape 21 is stretched and can achieve the winding of the tape 21, which helps to maintain environmental cleanliness.

[0050] Optionally, the drive component 142 is a motor to automate the peeling of the sheet material 30. For example, a servo motor or other type of motor. By driving the take-up shaft 141 to rotate via the motor, continuous and long-term peeling can be achieved.

[0051] In one embodiment, the traction assembly 14 includes a take-up shaft 141 for winding the stretch tape 21. The operator manually rotates the take-up shaft 141 to stretch the tape 21.

[0052] It should be noted that the traction component 14 includes, but is not limited to, the embodiments described above, which can stretch the tape 21. The tape 21 can drive the sheet material 30 through the peeling component 12. The configuration of the traction component 14 can be designed according to specific requirements.

[0053] In one embodiment, the unwinding assembly 13 includes a support base 131, a bearing 132, and a sliding shaft 133. The support base 131 includes a bottom wall and two side walls disposed on the bottom wall, the two side walls being spaced apart. The bearing 132 is fixed to the end face of the side wall of the support base 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.

[0054] In one embodiment, the sheet film peeling device 100 further includes a worktable 15 and a support 16. An unwinding assembly 13 is fixed to the worktable 15; specifically, the support base 131 of the unwinding assembly 13 is fixed to the worktable 15. A peeling guide rail 11 is fixed to the worktable 15 via the support 16. A peeling assembly 12 is fixed to the support 16 and located at the discharge end B of the peeling guide rail 11.

[0055] Optionally, the workbench 15 includes a table surface 151, support legs 152 supporting the table surface 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 surface 151. The traction assembly 14 is fixed to the support beam 153, that is, the traction assembly 14 is located on the lower side of the peeling guide rail 11, which helps to reduce the floor space occupied by the sheet bottom film peeling device 100.

[0056] Please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the sheet bottom film peeling mechanism provided in the embodiments of this application. Figure 6 This is a schematic diagram showing the relative positions of the sheet material and the gap.

[0057] This application embodiment also provides a sheet material bottom film peeling mechanism, which includes a sheet material bottom film peeling device 100 and a feeding device 200. The specific structural configuration of the sheet material bottom film peeling device 100 can be found in the above description and will not be repeated here. The feeding device 200 is used to attach the sheet material 30 to the surface of the adhesive tape 21.

[0058] It should be noted that the feeding device 200 is capable of picking up the sheet material 30 and placing it on the surface of a portion of the adhesive tape 21 located on the peeling guide rail 11. The specific structure of the feeding device 200 is designed according to needs. In some other embodiments, the sheet material 30 can also be placed on the surface of the portion of the adhesive tape 21 located on the peeling guide rail 11 manually.

[0059] In one embodiment, the outline of the sheet material 30 includes sharp edges; for example, the outline of the sheet material 30 is rhomboid. The feeding device 200 is used to position the sharp edges of the sheet material 30 toward the conveying direction of the tape, so that the part of the sheet material 30 that initially enters the gap 120 is the sharp edge, the bottom film 31 is easy to bend, maintaining smooth peeling, reducing the probability of jamming, and facilitating faster peeling speed.

[0060] Optionally, the corner of the sheet 30 facing the conveying direction of the tape 21 is defined as the first corner. The feeding device 200 is used to place the edge of the sheet 30 forming the first corner with the width direction of the tape 21 at an angle α greater than or equal to 30 degrees and less than or equal to 150 degrees. The bottom film 31 is easy to form a corner, which keeps the peeling smooth, reduces the probability of jamming, and helps to speed up the peeling speed.

[0061] Please see Figure 7 , Figure 7 This is a schematic flowchart of the method for peeling off the bottom film provided in the embodiments of this application.

[0062] The method for peeling off the bottom film provided in this application embodiment can be achieved by using the sheet bottom film peeling mechanism described in the above embodiments. The method for peeling off the bottom film specifically includes: 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 feed end A of the peeling guide 11, the discharge end B of the peeling guide 11, and the gap 120 in sequence, and fix the end of the tape 21 to the traction assembly 14.

[0063] Step S02: Use the feeding device 200 to attach several sheets 30 to the surface of the tape 21.

[0064] Specifically, the feeding device 200 places several sheets 30 on the surface of a portion of the tape 21 located on the peeling guide rail 11.

[0065] In one embodiment, the outline of the sheet material 30 includes sharp edges; for example, the outline of the sheet material 30 is rhomboid. The feeding device 200 is used to position the sheet material 30 with its sharp edges facing the conveying direction of the tape, and the angle formed between the edge of the sharp edge and the width direction of the tape 21 is greater than or equal to 30 degrees and less than or equal to 150 degrees. This makes it easier for the bottom film 31 to form sharp edges, maintaining smooth peeling, reducing the probability of jamming, and facilitating faster peeling speed.

[0066] 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 bottom film 31 and the material 32 are separated at the gap 120.

[0067] 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 with the tape 21, while 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 jamming.

[0068] In one embodiment, the sheet material 30 further includes a slicing ring 33, which is disposed on the surface of the bottom film 31 and surrounds the material 32. The peeling assembly 12 also includes a guide plate 123, which is disposed on the side of the guide plate 122 away from the peeling 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 slicing ring 33, so that the material 32 can be conveyed through the gap between the guide plate 122 and the guide plate 123, while the slicing ring 33 cannot pass through the gap between the guide plate 122 and the guide plate 123, thereby achieving the separation of the slicing ring 33 from the material 32, that is, achieving the synchronous separation of the material 32, the bottom film 31, and the slicing ring 33 of the sheet material 30.

[0069] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
