Description

Technical Field

[0001] The invention relates to a non-contact smart card processing device, in particular to a semi-automatic sheet material stacking and binding device. Background Art

[0002] In the contactless smart card manufacturing process, it is necessary to perform double-sided packaging and compounding of the smart card sheet that has completed winding, chip welding, ultrasonic compounding and cutting processing, that is, the upper covering sheet and the lower covering sheet are compound welded on the upper and lower surfaces of the smart card sheet, and the upper film tape is welded on the outer packaging of the upper covering sheet and the lower covering sheet to form a smart card board. The utility model patent "A composite processing production line for sheet materials" with the authorization announcement number CN 208256627U specifically discloses the use of three sets of conveying mechanisms to clamp and convey the corresponding sheet materials and complete the superposition. This undoubtedly increases the length of the entire equipment and has a complex structure. The debugging and installation accuracy of the three sets of conveying mechanisms are difficult to guarantee, which easily affects the final sheet material superposition accuracy. In addition, during the sheet material superposition process, the already superimposed upper cover sheet material and smart card sheet material need to be conveyed forward to the lower cover sheet material to complete the entire superposition process. This will cause the position of the already aligned superpositioned upper cover sheet material and smart card sheet material to be offset, thereby reducing the final superposition accuracy of the three sheets and affecting the quality of the finished product. At the same time, although the above-mentioned comparative document uses a fully automated method to complete the entire sheet material composite process, it requires the configuration of three corresponding feeding devices, resulting in a very large structure of the entire production line and high requirements for installation and debugging, which is not conducive to high-precision superposition processing of sheets. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a semi-automatic sheet stacking and binding device, which has high sheet stacking accuracy, occupies a small space, has low installation and debugging difficulty, and is conducive to improving the quality of subsequent smart card products.

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

[0005] A semi-automatic sheet material stacking and binding device, characterized in that it comprises a manual feeding module, a high-precision stacking module, a composite packaging welding module, a cutting module and a collecting module which are sequentially arranged along the moving direction of the sheet material; wherein,

[0007] The high-precision superposition module includes a superposition receiving platform, a clamping and conveying mechanism for conveying sheet materials, a middle pressing mechanism and a tail positioning mechanism; the tail positioning mechanism is arranged at the rear end of the superposition receiving platform along the moving direction of the sheet materials, and the middle pressing mechanism is arranged above the middle part of the superposition receiving platform; the middle pressing mechanism includes a pressing plate and a pressing driving mechanism for driving the pressing plate to move vertically; the tail positioning mechanism includes a moving part, a clamping part, a transverse driving mechanism for driving the moving part to move back and forth along the moving direction of the sheet materials, and a tail clamping driving mechanism for driving the clamping part to move vertically, and the clamping part is arranged on the moving part; when the clamping part is in a working state, the clamping part presses the rear end of the sheet materials located on the superposition receiving platform onto the superposition receiving platform;

[0008] The composite packaging welding module includes a film tape conveying device and an ultrasonic welding device for conveying the upper film tape and the lower film tape to the composite station;

[0009] The cutting module includes a cutter and a cutting drive mechanism for driving the cutter to cut the composite film strip;

[0010] The collecting module comprises a sheet material traction mechanism and a lifting and collecting mechanism, and the lifting and collecting mechanism is arranged below the sheet material traction mechanism.

[0011] The working principle of the above-mentioned semi-automatic sheet stacking and binding equipment is:

[0012] During work, the worker responsible for loading the materials places the lower covering sheet, smart card sheet and upper covering sheet on the loading belt in turn. Driven by the loading drive mechanism, the three sheets are transported to the rear of the overlapping receiving table in turn, waiting for the transportation by the clamping conveying mechanism and performing high-precision overlapping processing.

[0013] First, the lower covering sheet is conveyed to the overlapping receiving table under the conveyance of the clamping conveying mechanism, and then the clamping driving mechanism drives the pressing plate to move downward to press the lower covering sheet on the overlapping receiving table to ensure the positioning accuracy of the lower covering sheet; then, the tail positioning mechanism clamps and positions the rear end of the lower covering sheet, and the transverse driving mechanism drives the moving part to move backward, thereby driving the clamping part to move backward and leave the overlapping receiving table, and then the tail clamping driving mechanism drives the clamping part to rise, and the transverse driving mechanism drives the moving part to move forward again, and when the clamping part set on the moving part is above the rear end of the lower covering sheet, the tail clamping driving mechanism drives the clamping part to descend, thereby pressing the lower covering sheet on the overlapping receiving table (the movement process of the clamping part is: retreat-rise-forward-fall); The driving pressure plate rises and leaves the lower covering sheet. At this time, the clamping and conveying mechanism conveys the smart card sheet on the feeding belt to the top of the lower covering sheet and aligns it to complete the overlapping. After the clamping driving mechanism drives the pressure plate down again to clamp the middle of the smart card sheet and the lower covering sheet, the clamping and conveying mechanism releases the smart card sheet again to complete the overlapping of the smart card sheet and the lower covering sheet. Since the clamping part has clamped the rear end of the lower covering sheet at this time, the clamping part performs a rising-backward-rising-forward-falling movement process driven by the transverse driving mechanism and the tail clamping driving mechanism, thereby clamping the rear ends of the smart card sheet and the lower covering sheet. Finally, the clamping driving mechanism drives the pressure plate to rise, the clamping and conveying mechanism conveys the upper covering sheet to the top of the smart card sheet and aligns it, and the clamping driving mechanism drives the pressure plate to descend to complete the overlapping of the three sheets. After the three sheets are stacked, the clamping part first performs an upward and backward movement, and no longer clamps the rear end of the sheet. The pressure plate then rises and leaves the stacking receiving platform, and no longer presses the middle part of the sheet. Finally, the three stacked sheets are transported forward to the composite station through the clamping and conveying mechanism.

[0014] Under the action of the film tape conveying device, the upper film tape and the lower film tape are respectively conveyed to the top and bottom of the stacked sheet materials; at this time, the upper film tape, the smart card board (the stacked upper covering sheet material, the smart card board material and the lower covering sheet material) and the lower film tape are packaged and welded by the ultrasonic welding device, so that the film tape is compositely welded on the smart card board.

[0015] Subsequently, driven by the film tape conveying device, the smart card board that has completed the film tape composite welding will continue to be conveyed forward, and the smart card board will be handed over to the sheet material traction mechanism, and driven by the sheet material traction mechanism, the smart card board will continue to move forward to the top of the lifting and receiving mechanism; at this time, the cutting position of the film tape corresponds to the cutting station, and the cutting of the film tape is completed through the cutting module to form a separate smart card board; finally, the sheet material traction mechanism releases the smart card board, allowing the separate smart card board to fall into the lifting and receiving mechanism, completing the entire sheet material stacking and binding process.

[0020] A preferred embodiment of the present invention further includes a magnetic film tearing device, which is arranged at a corresponding position of the upper film tape roll; wherein the magnetic film tearing device includes a waste film winding mechanism and a broken film detection mechanism; the waste film winding mechanism includes a winding wheel and a winding driving mechanism for driving the winding wheel to rotate, and the waste film torn from the upper film tape is uniformly collected on the winding wheel; the broken film detection mechanism includes a plurality of sensing members and detection sensors, the plurality of sensing members are arranged along the width direction of the upper film tape, and the plurality of sensing members are arranged in a one-to-one correspondence with the plurality of waste films; wherein the connecting end of each sensing member is rotatably connected to the frame, the swinging end of the sensing member is placed on the waste film between the upper film tape and the winding wheel, and the waste film between the upper film tape and the winding wheel lifts the swinging end; the detection sensor is used to detect whether the swinging ends of the plurality of sensing members fall off.

[0027] 2. The high-precision stacking module of the present invention clamps the sheet material already on the stacking receiving table at the rear end through the tail positioning mechanism, so that the subsequent sheet material will not deviate from the sheet material already on the stacking receiving table when moving forward, thereby improving the positioning accuracy and stacking accuracy of the sheet material.

[0028] 3. In the traditional sheet stacking device, when the sheets are stacked, the middle clamping mechanism needs to rise away from the sheet on the stacking receiving table and no longer clamp, so that the subsequent sheets can move forward smoothly. At this time, no part of the sheet is fixed, and it is very easy to deviate, resulting in the inability to align the sheets when stacking, and poor stacking accuracy. The tail positioning mechanism of the present invention does not affect the normal transportation of subsequent sheets, and can effectively clamp and position the sheet, and cooperate with the middle clamping mechanism, so that the sheet is always clamped during the stacking process (middle clamping or rear end clamping), effectively improving the position accuracy of the sheet and achieving high-precision stacking of the sheet.

[0065] See also Fig.12, the pre-positioning device 2c also includes a slapping mechanism, which is arranged on the side opposite to the roller side-pull mechanism 2; the slapping mechanism includes a slapping plate 16 and a slapping driving mechanism 3 that drives the slapping plate 16 to move horizontally. During loading, when the edge of the sheet material is not accurately located between the upper pressing wheel 4 and the power wheel 5, the slapping driving mechanism 3 drives the slapping plate 16 to move inward, thereby pushing the sheet material to move to one side of the roller side-pull mechanism 2, ensuring that the edge of the sheet material is located between the upper pressing wheel 4 and the power wheel 5, and then positioning it through the roller side-pull mechanism 2. By setting up the slapping mechanism, the adaptability of the device is improved, and the inability to position the sheet material is avoided, thereby avoiding affecting the subsequent overlapping processing; at the same time, the slapping mechanism can also perform initial positioning of the sheet material, first perform preliminary positioning of the sheet material, adjust the sheet material to a relatively accurate position, and then accurately position it through the roller side-pull mechanism 2, which is conducive to improving the positioning accuracy.

[0066] See also Figure 12-14 In this embodiment, the vertical drive mechanism 13 is a needle-type cylinder, the positioning drive mechanism 6 is a motor, and the alignment drive mechanism 3 is a cylinder; the vertical drive mechanism 13 and the alignment drive mechanism 3 can be composed of other linear drive mechanisms.

[0067] See also Figure 7-Figure 14 The working principle of the high-precision superposition module 3c of this embodiment is:

[0068] First, under the action of the loading belt, the sheet to be overlapped is transported to the pre-positioning station 10c, which is arranged behind the overlapping receiving platform 2a. At this time, the edge of the sheet is located between the upper pressing wheel 4 and the power wheel 5; then, the vertical drive mechanism 13 drives the upper pressing wheel 4 to move downward, clamping the edge of the sheet between the upper pressing wheel 4 and the power wheel 5; then, the positioning drive mechanism 6 drives the power wheel 5 to rotate, driving the sheet to move to one side of the positioning plate 14, and under the action of the positioning plate 14, the side edge of the sheet is flush with the positioning surface of the positioning plate 14, thereby completing the positioning of the sheet. After the positioning is completed, the sheet material continues to move forward driven by the clamping and conveying mechanism and overlaps on the upper surface of other sheets. Since the edge of the positioned sheet material is aligned with the side edge of the sheet material in front, the neatness of the two sheets in the width direction can be ensured when overlapping. At this time, you only need to ensure the accuracy of the moving distance of the sheet material by the clamping and conveying mechanism to ensure the overlapping accuracy of the two sheets in the width and length directions.

[0069] Next, the clamping and conveying mechanism transports the pre-positioned sheets to the overlapping receiving platform 2a in sequence, thereby completing the overlapping of the sheets; wherein, the pre-positioned lower covering sheet is first transported to the overlapping receiving platform 2a, and then the clamping drive mechanism 18a drives the pressing plate to move downward, pressing the lower covering sheet on the overlapping receiving platform 2a, to ensure the positioning accuracy of the lower covering sheet. Next, the tail positioning mechanism 1a clamps and positions the rear end of the lower covering sheet; the transverse driving mechanism 20a drives the movable member 19a to move backward, thereby driving the clamping member 9a to move backward and away from the overlapping receiving platform 2a, and then the tail clamping driving mechanism 23a drives the clamping member 9a to rise, and the transverse driving mechanism 20a drives the movable member 19a to move forward again. When the clamping member 9a set on the movable member 19a is located above the rear end of the lower covering sheet, the tail clamping driving mechanism 23a drives the clamping member 9a to descend, thereby pressing the lower covering sheet onto the overlapping receiving platform 2a (the movement process of the clamping member 9A is: backward-upward-forward-downward). Next, the clamping drive mechanism 18a drives the pressing plate to rise and leave the lower covering sheet, and the clamping conveying mechanism conveys the smart card sheet to the top of the lower covering sheet and aligns it to complete the superposition. After the clamping drive mechanism 18a drives the pressing plate to descend again to compress the middle of the smart card sheet and the lower covering sheet, the clamping conveying mechanism releases the smart card sheet to complete the superposition of the smart card sheet and the lower covering sheet. Since the clamping member 9a has already pressed the rear end of the lower covering sheet at this time, the clamping member 9a performs the movement process of rising-backward-rising-forward-falling under the drive of the transverse driving mechanism 20a and the tail clamping driving mechanism 23a, thereby clamping the rear ends of the smart card sheet and the lower covering sheet. Finally, the clamping drive mechanism 18a drives the pressing plate to rise, the clamping conveying mechanism conveys the upper covering sheet to the top of the smart card sheet and aligns it, and the clamping drive mechanism 18a drives the pressing plate to descend to complete the superposition of the three sheets.

[0070] See also Figure 15-Figure 22 The magnetic stripe film tearing device of this embodiment includes a waste film winding mechanism and a broken film detection mechanism 4b; the waste film winding mechanism includes a winding wheel 1b and a winding driving mechanism 2b for driving the winding wheel 1b to rotate, and the waste film 19b torn from the upper film belt is uniformly collected on the winding wheel 1b; the broken film detection mechanism 4b includes a plurality of sensing members and a detection sensor, the plurality of sensing members are arranged along the width direction of the upper film belt, and the plurality of sensing members are arranged in a one-to-one correspondence with the plurality of waste films 19b; 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 19b located between the upper film belt and the winding wheel 1, and the waste film 19b located between the upper film belt and the winding wheel 1b lifts the swinging end; the detection sensor is used to detect whether the swinging ends of the plurality of sensing members fall off.

[0071] See also Figure 15-19The film break detection mechanism 4b also includes a plurality of steering support wheels 12b arranged below the tearing position of the upper film belt, the plurality of steering support wheels 12b are arranged in an array along the width direction of the upper film belt, and the plurality of steering support wheels 12b are arranged one by one with the plurality of sensing elements; the plurality of steering support wheels 12b are arranged in sequence from high to low along the moving direction of the waste film 19b, and the circumferential direction of the steering support wheel 12b is perpendicular to the moving direction of the upper film belt; the rotating end of the sensing element is arranged on the rotating shaft of the steering support wheel 12b; after the waste film 19b is torn off from the upper film belt, it bypasses the steering support wheel 12b and is collected on the winding wheel 1; the swing end of the sensing element is placed on the waste film 19b between the steering support wheel 12b and the winding wheel 1b. By setting the steering support wheel 12b, the collection of the waste film 19b is more convenient, and the waste film 19b can be further tightened so as to lift the swing end of the sensing element, thereby improving the accuracy of film break detection. The waste film 19b torn off from the upper film belt rotates ninety degrees and then winds around the steering support wheel 12b. After the multiple waste films 19b bypass the corresponding steering support wheels 12b, they extend to the same side and are finally collected on the winding wheel 1b. Since the multiple steering support wheels 12b are arranged in sequence from high to low, the multiple waste materials can avoid each other after bypassing the steering support wheels 12b, and are stacked and collected on the winding wheel 1b in sequence. At the same time, there is enough space in the height direction to provide for the swing end of the sensor to be placed. The design is ingenious, which can make the entire structure more compact and closer to the upper film belt, so that when the waste film 19b is broken, the swing end of the sensor can fall in time, thereby improving the accuracy of the broken film detection. In addition, the rotating end of the sensor is arranged on the rotating shaft of the steering support wheel 12b, which is convenient for installation and can save space.

[0072] See also Figure 17-Figure 19 , along the moving direction of the waste film 19b, a transition overlapping wheel 16b is provided in front of the steering support wheel 12b; after multiple waste films 19b are torn off from the upper film belt, they bypass the corresponding steering support wheel 12b, and are sequentially overlapped and bypassed by the transition overlapping wheel 16b, and finally collected on the winding wheel 1b. Through the setting of the transition overlapping wheel 16b, it is convenient to uniformly overlap and collect multiple waste films 19b to form a multi-layer waste film 19b, and finally collect it on the winding wheel 1b for recycling. In this embodiment, the transition overlapping wheel 16b is higher than the steering support wheel 12b, so that multiple waste films 19b can be better overlapped together, so as to facilitate recycling.

[0073] See also Figure 17-Figure 19, the sensing element includes a swing arm 13b and a pressure rod 23b, one end of the swing arm 13b is connected to the rotating shaft of the steering support wheel 12b, and the other end is connected to the pressure rod 23b; the pressure rod 23b and the swing arm 13b are arranged perpendicular to each other, and the pressure rod 23b is placed on the waste film 19b located between the steering support wheel 12b and the winding wheel 1b; the end of the swing arm 13b connected to the rotating shaft constitutes the rotating end, and the swing arm 13b constitutes the swinging end. By setting such a sensing element, the structure is simple and easy to install. The pressure rod 23b is placed on the waste film 19b, which can increase the pressure on the waste film 19b and increase the falling speed of the waste film 19 when it is broken, thereby facilitating the detection speed.

[0074] See also Figure 17-Figure 19 , a reversing wheel 14b is correspondingly arranged below each of the multiple steering support wheels 12b, and the circumferential direction of the reversing wheel 14b is arranged parallel to the moving direction of the upper film belt; the waste film 19b torn off from the upper film belt passes through the reversing wheel 14b and the steering support wheel 12b in sequence, and is collected on the winding wheel 1b. The arrangement of the reversing wheel 14b facilitates the waste film 19b to rotate ninety degrees and bypass the steering support wheel 12b, making the movement of the waste film 19b smoother and reducing the probability of disconnection. In this embodiment, the multiple reversing wheels 14b are all arranged on the same connecting rod 15b, and the two ends of the connecting rod 15b are respectively connected to the frame.

[0075] See also Fig.15 , Fig.16 and Fig. 20 , and also includes a film pressing mechanism 5b, which includes a support plate 8b and multiple groups of clamping components, and the multiple groups of clamping components are arranged on the support plate 8b; wherein each group of clamping components includes a clamping plate 10b and a film pressing driving mechanism 11b that drives the clamping plate 10b to move vertically, and the clamping plate 10b is arranged above the support plate 8b; the support plate 8b is provided with a film passing groove 9b for the waste film 19b to pass through. There are four groups of clamping components in this embodiment, which are respectively arranged at the four corners of the support plate 8b. The upper film belt starts from the upper film belt roll, passes through the support plate 8b and enters the conveying roller 7b. When the upper film belt stops conveying forward, the film pressing driving mechanism 11b drives the clamping plate 10b to move downward, thereby pressing the upper film belt on the support plate 8b to prevent the upper film belt from retreating and affecting the overlapping accuracy with the sheet material. In addition, during the movement of the upper film belt, the upper film belt passes through the upper surface of the support plate 8b, and the waste film 19b torn off from the upper film belt passes through the film passing groove 9b, then bypasses the reversing wheel 14b, the steering support wheel 12b and the transition overlapping wheel 16b, and is finally collected on the winding wheel 1b. In this embodiment, a mounting frame 22b is provided on the support plate 8b, and the clamping drive mechanism is composed of a cylinder, the cylinder body of which is fixedly connected to the mounting frame 22b, and the telescopic member of the cylinder is connected to the clamping plate 10b.

[0076] See also Fig.21 and Fig. 22 , the waste film winding mechanism also includes a shifting guide mechanism, which includes a guide member 21b and a shifting drive mechanism 20b that drives the guide member 21b to move along the axial direction of the winding wheel 1b; a limiting ring is provided on the guide member 21b, and the stacked waste film 19b passes through the limiting ring and is wound on the winding wheel 1b; along the moving direction of the waste film 19b, the guide member 21b is arranged behind the winding wheel 1. In this embodiment, the shifting drive mechanism 20b is composed of a motor and a screw transmission mechanism. By setting such a shifting guide mechanism, the stacked waste film 19b can be evenly wound on the winding wheel 1b, avoiding concentrated winding at a certain position of the winding wheel 1b, which is beneficial to improving the winding capacity of the winding wheel 1b.

[0077] See also Figure 17-Figure 19 The detection sensor includes a laser emitter 17b and a laser receiving plate 18b; the laser path of the laser emitter 17b is set below the plurality of steering support wheels 12b, and the laser path corresponds to the position of the swing end of the sensing element when it 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 17b, making it impossible for the laser receiving plate 18b to receive, thereby realizing the detection of the disconnection of the waste film 19b.

[0078] See also Fig.15 , Fig.16 and Fig. 22 A plurality of tension wheels 3b are provided between the transition overlapping wheel 16b and the guide member 21b; after the plurality of waste films 19b are overlapped together by the transition overlapping wheel 16b, they pass through the plurality of tension wheels 3b and the guide member 21b in sequence, and are finally rolled up on the winding wheel 1b. In this embodiment, the directions of the plurality of tension wheels 3b can be flexibly set, and along the moving direction of the waste film 19b, the direction of the front tension wheel 3b is consistent with the winding wheel 1b. By setting the tension wheel 3b, the waste film 19b can be kept in a taut posture, which is conducive to smoothly tearing the protective film from the upper film belt and smoothly moving it to the winding wheel 1b for recycling.

[0079] See also Fig.15 and Fig.16 In this embodiment, a brake 6b is provided on the rotating shaft of the upper film tape roll. By setting the brake 6b, the inertial rotation of the upper film tape roll can be reduced, thereby improving the movement accuracy of the upper film tape, which is beneficial to improving the subsequent overlapping packaging accuracy with the sheet material.

[0080] See also Figure 15-Figure 22 The working principle of the magnetic stripe film tearing device of this embodiment is:

[0081] Before the upper film belt is welded to the sheet material, the protective film is torn off from the upper film belt to form waste film 19b, and multiple separate waste films 19b are fixed on the winding wheel 1b; at the same time, the swing end support of each induction element is placed on the corresponding waste film 19b. When the upper film belt needs to move forward to overlap and encapsulate with the sheet material, the winding drive mechanism 2b drives the winding wheel 1b to rotate, so as to pull and collect the waste film 19b, thereby tearing off the protective film while the upper film belt moves forward. When all the protective films are successfully torn off, the waste film 19b between the upper film belt and the winding wheel 1b is in a taut state, so the swinging end of the sensing element can be kept lifted; when a certain waste film 19b is broken, the waste film 19b between the upper film belt and the winding wheel 1b cannot support the swinging end of the corresponding sensing element, so the swinging end of the sensing element will fall under the action of gravity, and thus 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 upper film belt to the sheet material package, thereby ensuring that the magnetic strip of the upper film belt after packaging can contact the sheet material, thereby ensuring the quality of the smart card product.
