Description

Technical Field

[0001] The present application relates to the field of automation technology, and in particular to an automatic waste film tearing device and a waste film tearing equipment. Background Art

[0002] For precision workpieces such as screens and casings used to assemble mobile phones, computers and other products, it is often necessary to cover the surface of the workpiece with a protective film in order to reduce the probability of scratches and other poor appearance caused by collisions during transportation; therefore, before assembling the product, it is necessary to remove the protective film covering the surface of the workpiece.

[0003] An existing technical means for removing the protective film on the surface of a workpiece includes the following steps:

[0004] First, the double-sided adhesive tape is bonded to a cotton swab; then, the cotton swab is manually held to contact the double-sided adhesive tape on the cotton swab with the protective film covering the surface of the workpiece, so that the double-sided adhesive tape and the protective film are bonded; finally, the cotton swab is moved away from the workpiece to separate the protective film from the workpiece, thereby achieving the effect of removing the protective film. However, the above manual operation is inefficient and needs to be improved. Utility Model Content

[0005] The present application provides an automatic waste film tearing device and a waste film tearing equipment to improve the efficiency of removing the protective film covering the surface of a workpiece.

[0006] The first aspect of an embodiment of the present application provides an automatic waste film tearing device, comprising a laminating module, a clamping module and a driving mechanism; the laminating module is configured to engage a tape with a handle portion with a protective film to be removed on a workpiece; the clamping module comprises a clamping drive and two clamping blocks, the clamping drive is connected to the driving structure, and is configured to drive at least one of the two clamping blocks to move so that the two clamping blocks are clamped on opposite sides of the tape; the driving mechanism is connected to the clamping drive, and is configured to drive the clamping drive to move, so as to drive the tape together with the protective film to move in a direction away from the workpiece.

[0007] The above-mentioned automatic waste film tearing device sticks the adhesive label on the protective film to be removed through the bonding module, and separates the adhesive label together with the protective film to be removed from the workpiece through the cooperation of the clamping module and the driving mechanism, which is conducive to achieving the effect of automatically removing the protective film covering the surface of the workpiece, thereby helping to improve the removal efficiency of the protective film.

[0008] In a possible implementation, the laminating module includes a negative pressure suction head and a laminating driving component, the negative pressure suction head is configured to adsorb the adhesive sticker, and the laminating driving component is configured to drive the negative pressure suction head to move.

[0009] In this implementation, the laminating driving member drives the negative pressure suction head to move, so that the adhesive sticker adsorbed by the negative pressure suction head can be moved synchronously.

[0010] In a possible implementation, the bonding module further includes a pressure-maintaining block and a pressure-maintaining driving component, and the pressure-maintaining driving component is configured to drive the pressure-maintaining block to move so that the pressure-maintaining block presses the bonding portion of the adhesive tape toward the protective film.

[0011] In this implementation, the pressure-maintaining block can press the adhesive portion of the adhesive tape, which is beneficial for fully engaging the adhesive portion of the adhesive tape with the protective film, thereby facilitating ensuring that the adhesive tape drives the protective film to separate from the workpiece.

[0012] In a possible implementation, the automatic waste film tearing device also includes a waste bucket; the driving mechanism is also configured to drive the clamping driving member to move toward the waste bucket, and the waste bucket is used to receive the protective film and adhesive label released by the clamping block.

[0013] In this implementation, the waste bucket is used to collect the protective film and adhesive sticker removed from the workpiece, thereby achieving unified collection and processing of the removed protective film.

[0014] In one possible implementation, the waste bucket is provided with an opening and a limit piece; the opening is configured to allow the protective film and the adhesive tape to enter the waste bucket; the limit piece is located at the opening and is configured to stop the adhesive tape when the driving mechanism drives the clamping driving piece to move away from the waste bucket.

[0015] In this implementation, after the two clamping blocks release the adhesive tape, the adhesive tape may abut against the limiting member during the process of the clamping drive member moving away from the waste bin, so that the adhesive tape is separated from the clamping blocks after being acted upon by the limiting member.

[0016] In a possible implementation, the automatic waste film tearing device further includes an air blowing pipe, which is disposed on the waste barrel or the driving mechanism, and is configured to blow air toward the handle of the adhesive label so as to move the adhesive label in a direction away from the clamping block.

[0017] In this implementation, when the clamping module releases the adhesive label, the gas blown out of the air blowing tube can exert force on the adhesive label and further promote the adhesive label to separate from the clamping block.

[0018] In a possible implementation, the gas blown out by the blowing pipe includes ion wind.

[0019] In this implementation, after the ion wind contacts the adhesive sticker or protective film, the charge in the ion wind can neutralize the charge on the adhesive sticker or protective film to reduce the static electricity of the adhesive sticker or protective film, thereby further facilitating the adhesive sticker to detach from the clamp.

[0020] In a possible implementation, the limiting member is provided with an air outlet, the air blowing pipe is connected to the limiting member, and the interior of the air blowing pipe is communicated with the air outlet, so that the air blown from the air outlet is blown toward the handle of the adhesive tape.

[0021] In this implementation, the blowing tube is connected to the limiting member, and the blowing end of the blowing tube can be connected to the limiting member so that the gas blown out from the outlet end of the blowing tube can be blown out from the outlet hole, which is beneficial to improve the stability of the airflow blowing toward the handle of the adhesive label.

[0022] In a possible implementation, the limiting member extends obliquely from the barrel wall of the waste barrel toward the interior of the waste barrel.

[0023] In this implementation, the limiting member is arranged at an angle, and the limiting member has a limiting effect on the movement of the adhesive label to the outside of the waste bin, thereby helping to reduce the probability of the protective film flying to the outside of the waste bin.

[0024] In a possible implementation, one of the two clamping blocks is disposed on the driving mechanism, and the other is rotatably disposed on the driving mechanism and connected to a clamping driving member, and the clamping driving member is configured to drive the clamping block to rotate.

[0025] In this implementation, the clamping block is rotatably arranged on the driving mechanism, and the structure is simple and compact.

[0027] In this implementation, the film tearing drive and the transfer drive cooperate with each other to drive the clamping drive to move away from or close to the workpiece along the thickness direction of the adhesive tape and / or the first direction, thereby increasing the moving range of the clamping drive, thereby facilitating the movement of the torn protective film to a position away from the workpiece, so as to facilitate the collection and unified treatment of the waste film.

[0028] In a possible implementation, the driving mechanism also includes a fixed bracket and an adjustment driving member, and the transfer frame and the adjustment driving member are both arranged on the fixed bracket; the adjustment driving member is configured to drive the transfer frame to move along a second direction, and the second direction is parallel to the adhesive tape and perpendicular to the first direction.

[0029] In this implementation, the clamping drive member can move in three mutually perpendicular directions, which is beneficial to improving the flexibility of the movement of the clamping drive member, and at the same time is beneficial to further increase the moving range of the clamping drive member, further facilitating the collection of the torn protective film.

[0030] The second aspect of the embodiments of the present application provides a waste film tearing device, including a circulating material tray, a machine base, a transmission device, a feeding module and the above-mentioned automatic waste film tearing device; the circulating material tray is configured to place the workpiece from which the protective film is to be removed; the machine base is sequentially provided with a pasting station and a film tearing station along its own length direction; the transmission device is configured to drive the circulating material tray to move to the pasting station and the film tearing station in sequence; the feeding module is configured to convey adhesive stickers; the bonding module is configured to join the adhesive stickers located at the feeding module with the protective film of the workpiece located at the pasting station, and the clamping module is configured to clamp the adhesive stickers at the workpiece located at the film tearing station.

[0031] The above-mentioned waste film tearing equipment automatically conveys the adhesive tape through the feeding module and automatically sticks the adhesive tape through the bonding module. The transmission device then transfers the circulating material tray on the workpiece with the adhesive tape to the film tearing station. The driving mechanism and the clamping module cooperate with each other to automatically remove the protective film of the workpiece. It has a high degree of automation, which is beneficial to improving the removal efficiency of the protective film of the workpiece.

[0032] In a possible implementation, the waste film tearing device further includes a visual positioning module, and the visual positioning module is configured to detect the position of the workpiece located at the pasting station.

[0033] In this implementation, the visual positioning module can detect and locate the position of the workpiece located at the pasting station, thereby helping to improve the accuracy of the position of the adhesive sticker.

[0034] In one possible implementation, the waste film tearing equipment also includes a unloading module and a visual inspection module. The visual inspection module is configured to detect whether the protective film of the workpiece output by the film tearing station has been removed; the unloading module is configured to transfer the workpiece output by the film tearing station to sort the workpieces whose protective film has been removed.

[0035] In this implementation, the visual inspection module can detect the workpiece after the film is torn off to detect whether the protective film has been removed; in conjunction with the unloading module, the workpiece can be automatically sorted, with a high degree of automation, which is conducive to further improving work efficiency.
