[0001] The invention relates to a smart card sheet material processing device, in particular to a magnetic stripe film tearing device of a sheet material laminating device. Background Art

[0002] In the manufacturing process of contactless smart cards, it is necessary to perform double-sided packaging and compounding of the smart card sheets that have completed winding, chip welding, ultrasonic compounding and cutting, that is, to compound weld the upper covering sheet and the lower covering sheet on the upper and lower surfaces of the smart card sheets, and to weld the upper covering sheet and the lower covering sheet on the outer packaging of the upper covering sheet and the lower covering sheet, so as to form a smart card board. Among them, the film strip is provided with a plurality of magnetic strips arranged at equal intervals. In order to protect the magnetic strips on the film strip during production, a protective film will be packaged and welded on the magnetic strip position of the film strip to prevent the magnetic strip from being damaged during transportation; however, in the process of packaging the film strip after the sheets are stacked, it is necessary to tear off the protective film and then package it so that the magnetic strip can contact the smart card board. There is still no device in the prior art that can tear the film for the film strip, so it is necessary to propose a magnetic stripe tearing device for sheet stacking equipment. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide a magnetic stripe film tearing device for a sheet material stacking device, which can smoothly tear off multiple protective films on the film strip, ensuring that the sheet material after stacking is packaged with the film strip, and can promptly detect whether the waste film is broken so as to adjust the equipment, thereby ensuring that the packaged sheet material can effectively contact the magnetic stripe on the film strip.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0006] The working principle of the magnetic strip film tearing device of the above-mentioned sheet material lamination equipment is:

[0007] Before the film strip is packaged and welded with the sheet material, the protective film is torn off from the film strip to form waste film, and multiple separate waste films are fixed on the winding wheel; at the same time, the swing end support of each sensor is placed on the corresponding waste film. When the film strip needs to move forward to overlap and package with the sheet material, the winding drive mechanism drives the winding wheel to rotate to pull and collect the waste film, so that the protective film can be torn off while the film strip moves forward. When all the protective films are torn off smoothly, the waste film between the film strip and the winding wheel is in a taut state, so the swing end of the sensor can be kept lifted; when a certain waste film is disconnected, the waste film between the film strip and the winding wheel cannot support the swing end of the corresponding sensor, so the swing end of the sensor will fall under the action of gravity, and then be detected by the detection sensor, so as to remind the workers to stop the machine for maintenance, avoid welding the protective film on the film strip with the sheet material package, thereby ensuring that the packaged film strip magnetic strip can contact the sheet material and ensure the quality of the smart card finished product.

[0008] In a preferred embodiment of the present invention, the broken film detection mechanism also includes a plurality of steering support wheels arranged below the film tearing position of the film strip, the plurality of steering support wheels are arranged along the width direction of the film strip, and the plurality of steering support wheels are arranged in one-to-one correspondence with the plurality of sensing elements; after the waste film is torn off from the film strip, it bypasses the steering support wheel and is collected on the winding wheel; the swinging end of the sensing element is placed on the waste film between the steering support wheel and the winding wheel.

[0009] Preferably, the multiple steering support wheels are arranged in sequence from high to low along the moving direction of the waste film, and the circumferential direction of the steering support wheel is perpendicular to the moving direction of the film strip; the rotating end of the sensor is arranged on the rotating shaft of the steering support wheel.

[0011] Preferably, a transition overlapping wheel is provided in front of the steering support wheel along the moving direction of the waste film; after multiple waste films are torn off from the film strip, they pass around the corresponding steering support wheels, and are overlapped and passed around the transition overlapping wheel in sequence, and finally collected on the winding wheel.

[0012] Preferably, a reversing wheel is correspondingly provided below the multiple steering support wheels, and the circumferential direction of the reversing wheel is arranged parallel to the moving direction of the film strip; the waste film torn off from the film strip passes through the reversing wheel and the steering support wheel in sequence and is collected on the winding wheel.

[0013] A preferred embodiment of the present invention further includes a film pressing mechanism, which includes a support plate and multiple groups of clamping assemblies, and the multiple groups of clamping assemblies are arranged on the support plate; wherein each group of clamping assemblies includes a clamping plate and a film pressing driving mechanism for driving the clamping plate to move vertically, and the clamping plate is arranged above the support plate; and a film passing groove for waste film to pass through is provided on the support plate.

[0019] 2. When a piece of waste film is broken, the waste film between the film belt and the winding wheel cannot support the swinging end of the corresponding sensing element.

[0025] The present invention is further described below in conjunction with examples and drawings, but the embodiments of the present invention are not limited thereto.

[0026] Example 1

[0027] See also Figure 1-Figure 8 The magnetic film tearing device of the sheet material stacking equipment of this embodiment includes a waste film winding mechanism and a broken film detection mechanism 4; the waste film winding mechanism includes a winding wheel 1 and a winding driving mechanism 2 for driving the winding wheel 1 to rotate, and the waste film 19 torn from the film strip is uniformly collected on the winding wheel 1; the broken film detection mechanism 4 includes a plurality of sensing members and detection sensors, the plurality of sensing members are arranged along the width direction of the film strip, and the plurality of sensing members are arranged one by one corresponding to the plurality of waste films 19; wherein the connection end of each sensing member is rotatably connected to the frame, the swinging end of the sensing member is placed on the waste film 19 between the film strip and the winding wheel 1, and the waste film 19 between the film strip and the winding wheel 1 lifts the swinging end; the detection sensor is used to detect whether the swinging ends of the plurality of sensing members fall off.

[0028] See also Figure 1-Figure 5The film break detection mechanism 4 also includes a plurality of steering support wheels 12 arranged below the tearing position of the film strip, the plurality of steering support wheels 12 are arranged in an array along the width direction of the film strip, and the plurality of steering support wheels 12 are arranged one by one with the plurality of sensing elements; the plurality of steering support wheels 12 are arranged in sequence from high to low along the moving direction of the waste film 19, and the circumferential direction of the steering support wheel 12 is perpendicular to the moving direction of the film strip; the rotating end of the sensing element is arranged on the rotating shaft of the steering support wheel 12; after the waste film 19 is torn off from the film strip, it bypasses the steering support wheel 12 and is collected on the winding wheel 1; the swinging end of the sensing element is placed on the waste film 19 between the steering support wheel 12 and the winding wheel 1. The arrangement of the steering support wheel 12 makes it more convenient to collect the waste film 19, and the waste film 19 can be further tightened so as to lift the swinging end of the sensing element, thereby improving the accuracy of film break detection. The waste film 19 torn off from the film strip is rotated ninety degrees and then wound around the steering support wheel 12. After the multiple waste films 19 pass the corresponding steering support wheels 12, they extend to the same side and are finally collected on the winding wheel 1. Since the multiple steering support wheels 12 are arranged in sequence from high to low, the multiple waste materials can avoid each other after passing the steering support wheels 12, and are stacked and collected on the winding wheel 1 in sequence. At the same time, there is enough space in the height direction for the swing end of the sensor to be placed. The design is ingenious, which can make the whole structure more compact and closer to the film strip, so that when the waste film 19 is broken, the swing end of the sensor can fall in time, thereby improving the detection accuracy of broken film. In addition, the rotating end of the sensor is arranged on the rotating shaft of the steering support wheel 12, which is convenient for installation and can save space.

[0029] See also Figure 3-Figure 5 , along the moving direction of the waste film 19, a transition overlapping wheel 16 is provided in front of the steering support wheel 12; after multiple waste films 19 are torn off from the film strip, they bypass the corresponding steering support wheel 12, and are sequentially overlapped and bypassed by the transition overlapping wheel 16, and finally collected on the winding wheel 1. Through the provision of the transition overlapping wheel 16, it is convenient to uniformly overlap and collect multiple waste films 19 to form a multi-layer waste film 19, and finally collect it on the winding wheel 1 for recycling. In this embodiment, the transition overlapping wheel 16 is higher than the steering support wheel 12, so that multiple waste films 19 can be better overlapped together, so as to facilitate recycling.

[0030] See also Figure 3-Figure 5The sensing element includes a swing arm 13 and a pressure rod 23. One end of the swing arm 13 is connected to the rotating shaft of the steering support wheel 12, and the other end is connected to the pressure rod 23. The pressure rod 23 and the swing arm 13 are arranged perpendicular to each other, and the pressure rod 23 is placed on the waste film 19 between the steering support wheel 12 and the winding wheel 1. The end of the swing arm 13 connected to the rotating shaft constitutes the rotating end, and the swing arm 13 constitutes the swinging end. By setting such a sensing element, the structure is simple and easy to install. The pressure rod 23 is placed on the waste film 19, which can increase the pressure on the waste film 19 and increase the falling speed of the waste film 19 when it is broken, which is conducive to improving the detection speed.

[0031] See also Figure 3-Figure 5 , a reversing wheel 14 is correspondingly arranged below each of the plurality of steering support wheels 12, and the circumferential direction of the reversing wheel 14 is arranged parallel to the moving direction of the film strip; the waste film 19 torn off from the film strip passes through the reversing wheel 14 and the steering support wheel 12 in sequence, and is collected on the winding wheel 1. The arrangement of the reversing wheel 14 facilitates the waste film 19 to rotate ninety degrees and bypass the steering support wheel 12, so that the movement of the waste film 19 is smoother and the probability of disconnection is reduced. In this embodiment, the plurality of reversing wheels 14 are all arranged on the same connecting rod 15, and the two ends of the connecting rod 15 are respectively connected to the frame.

[0032] See also Figure 1 , Figure 2 and Figure 6 , also includes a film pressing mechanism 5, which includes a support plate 8 and a plurality of clamping assemblies, and the plurality of clamping assemblies are arranged on the support plate 8; wherein each group of clamping assemblies includes a clamping plate 10 and a film pressing driving mechanism 11 for driving the clamping plate 10 to move vertically, and the clamping plate 10 is arranged above the support plate 8; the support plate 8 is provided with a film passing groove 9 for the waste film 19 to pass through. There are four groups of clamping assemblies in this embodiment, which are respectively arranged at the four corners of the support plate 8. The film tape starts from the film tape roll, passes through the support plate 8 and enters the conveying roller 7. When the film tape stops conveying forward, the film pressing driving mechanism 11 drives the clamping plate 10 to move downward, thereby pressing the film tape against the support plate 8 to prevent the film tape from retreating and affecting the overlapping accuracy with the sheet material. In addition, during the movement of the film tape, the film tape passes through the upper surface of the support plate 8, and the waste film 19 torn off the film tape passes through the film passing groove 9, then bypasses the reversing wheel 14, the steering support wheel 12 and the transition overlapping wheel 16, and is finally collected on the winding wheel 1. In this embodiment, a mounting frame 22 is provided on the support plate 8, and the clamping drive mechanism is composed of a cylinder, the cylinder body of the cylinder is fixedly connected to the mounting frame 22, and the telescopic member of the cylinder is connected to the clamping plate 10.

[0033] See also Figure 7 and Figure 8, the waste film winding mechanism also includes a shifting guide mechanism, which includes a guide member 21 and a shifting drive mechanism 20 that drives the guide member 21 to move along the axial direction of the winding wheel 1; a limiting ring is provided on the guide member 21, and the stacked waste film 19 passes through the limiting ring and is wound on the winding wheel 1; along the moving direction of the waste film 19, the guide member 21 is arranged behind the winding wheel 1. In this embodiment, the shifting drive mechanism 20 is composed of a motor and a screw transmission mechanism. By providing such a shifting guide mechanism, the stacked waste film 19 can be evenly wound on the winding wheel 1, avoiding concentrated winding at a certain position of the winding wheel 1, which is beneficial to improving the winding capacity of the winding wheel 1.

[0034] See also Figure 3-Figure 5 The detection sensor includes a laser emitter 17 and a laser receiving board 18; the laser path of the laser emitter 17 is set below the multiple steering support wheels 12, and the laser path corresponds to the position when the swing end of the sensing element falls. In this way, when the swing end of one of the sensing elements falls, it will block the light path emitted by the laser emitter 17, making it impossible for the laser receiving board 18 to receive, thereby realizing the detection of the waste film 19 being broken.

[0035] See also Figure 1 , Figure 2 and Figure 8 , a plurality of tension wheels 3 are arranged between the transition laminating wheel 16 and the guide member 21; after the plurality of waste films 19 are laminated together through the transition laminating wheel 16, they pass through the plurality of tension wheels 3 and the guide member 21 in sequence, and are finally wound up on the winding wheel 1. In this embodiment, the directions of the plurality of tension wheels 3 can be flexibly set, and along the moving direction of the waste film 19, the direction of the front tension wheel 3 is consistent with the winding wheel 1. By setting the tension wheel 3, the waste film 19 can be kept in a taut posture, which is conducive to smoothly tearing the protective film from the film belt and smoothly moving it to the winding wheel 1 for recycling.

[0036] See also Figure 1 and Figure 2 In this embodiment, a brake 6 is provided on the rotating shaft of the film strip roll. By setting the brake 6, the inertial rotation of the film strip roll can be reduced, thereby improving the movement accuracy of the film strip, which is beneficial to improving the subsequent overlapping packaging accuracy with the sheet material.

[0037] See also Figure 1-Figure 8 The working principle of the magnetic strip film tearing device of the sheet material stacking equipment of this embodiment is:

[0038] Before the film strip is packaged and welded with the sheet material, the protective film is torn off from the film strip to form waste film 19, and multiple separate waste films 19 are fixed on the winding wheel 1; at the same time, the swing end support of each induction element is placed on the corresponding waste film 19. When the film strip needs to move forward to overlap and package with the sheet material, the winding drive mechanism 2 drives the winding wheel 1 to rotate, so as to pull and collect the waste film 19, thereby tearing off the protective film while the film strip moves forward. When all the protective films are successfully torn off, the waste film 19 between the film tape and the winding wheel 1 is in a taut state, so that the swinging end of the sensing piece can be kept lifted; when a certain waste film 19 is broken, the waste film 19 between the film tape and the winding wheel 1 cannot support the swinging end of the corresponding sensing piece, so the swinging end of the sensing piece will fall under the action of gravity and be detected by the detection sensor, so as to remind the workers to stop the machine for maintenance and avoid welding the protective film on the film tape to the sheet material package, thereby ensuring that the packaged film tape magnetic strip can contact the sheet material and ensure the quality of the smart card product.

[0039] Example 2

[0040] The difference between this embodiment and embodiment 1 is that the circumferential direction of the plurality of steering support wheels 12 is arranged parallel to the moving direction of the film strip. By arranging such steering support wheels 12, the waste film 19 can be directly wound around the steering support wheels 12 after being torn off the film strip, thereby reducing torsion and making the structure simpler.

[0041] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
