In one embodiment of the present application, a film uncovering device includes a part of or all of the structures of the following embodiments; namely, the film uncovering device comprises part of or all of the following technical features. In one embodiment, a film uncovering device comprises a driving structure, a transmission structure, a rotating structure and a film uncovering structure; the driving structure is connected with the transmission structure, the transmission structure is connected with the rotating structure, and the film uncovering structure is fixed on the rotating structure; the driving structure drives the transmission structure to reciprocate so as to drive the rotating structure to reciprocate and synchronously drive the film uncovering structure to reciprocate; the film uncovering structure is in contact with the material covering film in a rotating state, and the material covering film is uncovered from the loading area through the film uncovering structure in the contact state of the film uncovering structure and the material covering film. According to the film uncovering device, the film uncovering structure is rotated in a reciprocating mode, so that the material covering film uncovering from the loading area is realized, and on one hand, the material receiving failure caused by the fact that the material covering film is not stripped is avoided; on the other hand, the film uncovering effect is guaranteed, and the material covering film which is uncovered can not be accumulated because the film uncovering structure rotates reciprocally; on the other hand, the device has the advantages of simple structure, small size, energy consumption saving and low cost, and is suitable for continuous production of large-scale material belts.
In one embodiment, as shown in fig. 2, a film uncovering device comprises a driving structure 210, a transmission structure 220, a rotating structure 230 and a film uncovering structure 240; the driving structure 210 is connected with the transmission structure 220. In this embodiment, the transmission structure 220 is engaged with the rotation structure 230. The transmission structure 220 is a rack, and the driving structure 210 drives the rack to linearly reciprocate; and/or, the rotating structure 230 is a gear, and the driving structure 220 drives the gear to reciprocally rotate. When the driving structure 210 drives the rack to linearly move downwards, the rack drives the gear to rotate anticlockwise, and the gear drives the film uncovering structure 240 to rotate anticlockwise; when the driving structure 210 drives the rack to linearly move upwards, the rack drives the gear to rotate clockwise, and the gear drives the film uncovering structure 240 to rotate clockwise. It will be appreciated that clockwise rotation and counter-clockwise rotation are relative terms, such as the point of view of the reader reading this specification and the drawings, as a frame of reference for both clockwise rotation and counter-clockwise rotation. In this embodiment, the driving structure 210 drives the transmission structure 220 to linearly reciprocate; in other embodiments, the driving structure 210 drives the transmission structure 220 to reciprocate.
Referring to fig. 3 and 4, the transmission structure 220 is connected to the rotating structure 230, and the film uncovering structure 240 is fixed on the rotating structure 230; the driving structure 210 drives the transmission structure 220 to reciprocate, so as to drive the rotating structure 230 to reciprocate, and synchronously drive the film uncovering structure 240 to reciprocate. In this embodiment, the rotating structure 230 and the film uncovering structure 240 rotate coaxially, i.e. the rotational angular speeds of the two are the same. The design is beneficial to accurately controlling the rotation state and the rotation position of the film uncovering structure 240 by controlling the movement state and the position of the transmission structure 220, so as to ensure that the film uncovering structure 240 uncovers the material covering film 120 from the loading area 110, so as to avoid film uncovering errors.
In one embodiment, as shown in fig. 5, the film uncovering structure 240 has a state of contacting with the material cover film 120 in a rotating state, and the material cover film 120 is uncovered from the loading area 110 by the film uncovering structure 240 in a state that the film uncovering structure 240 contacts with the material cover film 120. In one embodiment, the release film structure 240 releases the material cover film 120 from the loading zone 110 by adhesive, vacuum suction, or flexible pushing. Further, another idea may be adopted, the film uncovering structure 240 is only in contact with the material covering film 120, and in a state that the film uncovering structure 240 is in contact with the material covering film 120, the interaction pressure between the film uncovering structure 240 and the material covering film 120 is zero, that is, no additional acting force is applied, and the film uncovering structure 240 only has a guiding effect on the material covering film 120. In combination with the embodiment having a hot end, the portion of the material covering film 120 is actively wound around the film uncovering structure 240, and at this time, under the effect of the reciprocating rotation of the film uncovering structure 240, the film uncovering structure 240 can generate a traction force on the material covering film 120 in the circumferential direction of rotation. By means of the design, the material covering film is lifted off from the loading area by the reciprocating rotation of the film lifting structure.
In one embodiment, as shown in fig. 3, the film uncovering structure 240 has a body 241, and a plane portion 242 and a cambered surface portion 243 are disposed on the body 241; in the rotated state, the flat surface portion 242 or the arc surface portion 243 has a state of contact with the material cover film 120. In this embodiment, the film removing structure 240 or the body 241 thereof is mounted on the rotating structure 230, i.e. the gear, through a concentric shaft 250, so that the film removing structure 240 and the rotating structure 230 rotate coaxially, i.e. when the rotating structure 230 rotates, the film removing structure 240 also rotates, and at this time, the concentric shaft 250 is fixed relative to both the film removing structure 240 and the rotating structure 230. Further, the film uncovering structure 240 is a silica gel wheel, or the film uncovering structure 240 is a triangular wheel; further, the film uncovering structure 240 is a triangle silica gel wheel. Wherein, triangle wheel can have triangle-shaped body and fillet.
In one embodiment, the film uncovering structure 240 has a state of winding the material cover film 120 in a reciprocating rotation state and a state of releasing the wound material cover film 120. Further, the film uncovering structure 240 has a state of winding the material cover film 120 at least two times in a reciprocating rotation state, and has a state of completely releasing the wound material cover film 120 in a reciprocating rotation state. Referring to fig. 5 and 6, when the film uncovering structure 240 rotates clockwise, the film uncovering structure 240 has a state of winding the material cover film 120, and when the film uncovering structure 240 rotates counterclockwise, the film uncovering structure 240 has a state of releasing the wound material cover film 120. In this embodiment, the cambered surface portion 243 has a state of contact with the material cover film 120. The design is beneficial to realizing the uncovering of the material covering film from the loading area by reciprocally rotating the uncovering structure on one hand, and on the other hand, the uncovering structure is beneficial to realizing the separation of the material covering film from the uncovering structure by reciprocally rotating the uncovering structure, and the uncovering structure can wind at least part of the material covering film by only clockwise rotating a certain angle, and the certain angle can be more than 360 degrees or 720 degrees, etc. as can be seen from the realization principle; and vice versa, the material covering film can be completely separated from the film uncovering structure by rotating the film uncovering structure counter clockwise by the same certain angle due to the reciprocating rotation, so that the material covering film after the film uncovering is completed can not be remained and wound on the film uncovering structure, and can repeatedly run, and the problem of residual winding of the material covering film is avoided.
In one embodiment, as shown in fig. 7 and 8, the film uncovering structure 240 has a state of contacting the material cover film 120 in a rotating state, so that the material cover film 120 is uncovered from the loading area 110 of the material belt 100.
In one embodiment, as shown in fig. 9 and 10, the driving structure 210 is provided with a connecting end 211, a motor 212, a guide rail 213 and a sliding seat 214; the transmission structure 220 is fixed on the sliding seat 214; the motor 212 is connected to a power supply through the connection end 211, and the motor 212 drives the sliding seat 214 to reciprocate on the guide rail 213, so as to drive the transmission structure 220 to reciprocate. In this embodiment, the transmission structure 220 is a rack, the rotation structure 230 is a gear, and the transmission structure 220 is in meshing connection with the rotation structure 230; the motor 212 may be an electric cylinder.
In order to solve the problem that the material cover film 120 is passively stressed to be separated from the loading area 110, and that the passive stress may affect the loading area 110 or damage components therein, in one embodiment, as shown in fig. 11 and 12, the film peeling apparatus further includes a hot end 260, the hot end 260 is disposed adjacent to the film peeling structure 240, and the material cover film 120 is heated by the hot end 260 in a state that the film peeling structure 240 is in contact with the material cover film 120, so that the material cover film 120 is partially wound around the film peeling structure 240 and is peeled from the loading area 110 in a rotating state of the film peeling structure 240. In one embodiment, the hot side 260 includes a hot air output and an electrically heated side. From a safety controllable perspective, the hot end 260 may optionally use a hot air output to accurately control the thermal energy output. Wherein the material cover film 120 is partially wound around the film uncovering structure 240, and the contact part between the material cover film 120 and the film uncovering structure 240 exceeds 1 cm, or the contact part between the material cover film 120 and the film uncovering structure 240 exceeds 15% of the outer contour of the film uncovering structure 240.
In one embodiment, as shown in fig. 13 and 14, the hot end 260 is disposed adjacent to the film uncovering structure 240, and in combination with fig. 1 and 15, the hot end 260 is disposed adjacent to the peeling opening 121 of the material cover film 120 of the material belt 100, and the peeling opening 121 is a position where the material cover film 120 is separated from the loading area 110. Further, the hot air output end outputs hot air of 43±1 degree celsius to the peeling port of the material cover film 120 for 1.7±0.2 seconds, and the hot air output end is 13±2mm from the peeling port. By adopting the design, the material cover film 120 actively leaves the loading area 110, namely the material cover film 120 deforms in a heated state, and the deformation appears as curling deformation away from the loading area 110 from the stripping opening, so that the material cover film 120 does not need to be passively stressed to be separated from the loading area 110, namely the loading area 110 and components on the material cover film are not subjected to other external forces except short-time hot air in the film stripping process, and the material cover film is stripped from the loading area, so that the material failure caused by the fact that the material cover film is not stripped is avoided; on the other hand, the device is beneficial to protecting the loading area and the components thereon, thereby avoiding the possibility of damaging the loading area and the components thereon in the film uncovering process, and further ensuring the manufacturing yield of the product.
Further, in one embodiment, the hot end is disposed separately from the film uncovering structure. In one embodiment, the hot end is secured to a mounting bracket of the drive structure or to a stationary portion of the drive structure. Further, in one embodiment, the film uncovering device further comprises an electric heating device connected with the hot end, and the electric heating device is used for heating the material covering film through the hot end. In one embodiment, the electrothermal device heats the material cover film through the hot end in a manner that heats the hot end. Further, the electric heating device comprises a hot air blower, wherein the hot air blower is used for providing hot air and outputting the hot air through the hot air output end. In one embodiment, the hot air blower is used for providing hot air at the output position of the hot air output end at 43+/-1 ℃; that is, the air outlet temperature of the air heater is higher than 43+/-1 ℃ so that the output position of the hot air at the hot air output end is 43+/-1 ℃, and the output of the hot air output end is accurately controlled.
For the film uncovering device with a hot end, in one embodiment, the film uncovering structure 240 has a state of winding the material cover film 120 in a reciprocating rotation state and a state of releasing the wound material cover film 120. Further, in one embodiment, the film uncovering device further includes a controller connected with the electric heating device, the controller is further connected with the driving structure, the controller is used for controlling the driving structure and the electric heating device in a linkage mode, so that when the driving structure drives the transmission structure to drive the rotating structure and the film uncovering structure to rotate reciprocally, the film uncovering structure is controlled to output hot air through the hot air output end in a state of being contacted with the material covering film, and the material covering film is automatically curled on the film uncovering structure from the loading area, so that the material covering film is uncovered from the loading area through the film uncovering structure. The design is favorable for realizing automatic film uncovering treatment, and on one hand, the labor cost and the labor resource are reduced; on the other hand, the accuracy and the effectiveness of the film uncovering are improved, so that the automatic material receiving of a machine is realized in a matched manner; on the other hand, each structural member has small size, and the whole structure is simple and easy to operate.
