Description

Technical Field

[0001] The present invention relates to the technical field of film tearing machines, in particular to a film tearing and waste discharging machine. Background Art

[0002] With the continuous development of technology and the improvement of people's living standards, mobile phones and tablets have become indispensable electronic devices in our daily lives. During the assembly process of mobile phones and tablets, many auxiliary materials of varying sizes need to be attached. After the auxiliary materials are attached, the release film attached to these auxiliary materials needs to be removed for subsequent assembly operations. Currently, this process of removing the auxiliary film is handled manually, which has the following drawbacks:

[0003] 1) Inefficiency: The current manual process of removing excipients from the film consumes significant time and manpower. Each worker requires training and management, which increases production costs. Furthermore, due to labor limitations, this process is inefficient and cannot meet the needs of large-scale, efficient production. In today's increasingly competitive market, improving production efficiency is key to a company's survival and development.

[0004] 2) Unstable quality: Human operation can be affected by various factors such as fatigue and mood, resulting in inconsistent film tearing quality. Sometimes, the film may not be torn cleanly or the auxiliary materials may be torn, which will affect product quality. These quality issues may affect the performance and appearance of the product and even cause product failure.

[0005] 3) High cost: Manual processing requires consideration of worker wages, training, and management, all of which increase product costs. In a highly competitive market, reducing costs is key to improving competitiveness. Improving efficiency and stability through technological means can potentially reduce costs.

[0079] See also Figure 1 、 Figure 2, this embodiment provides a film tearing and waste discharge machine, including a frame 1, a feed guide and limiting mechanism 2, a loading mechanism 3, a clamp transfer and positioning mechanism 4, a film tearing mechanism 5, a discharge mechanism 6 and a discharge turning mechanism 7. The feed guide and limiting mechanism 2 is installed on the frame 1 and is located above the existing external material conveying line. The feed guide and limiting mechanism 2 is used to guide the material conveyed from the material conveying line to the loading station. The loading mechanism 3 is installed on the frame 1 and is located above the loading station. The loading mechanism 3 is used to grab the material conveyed to the loading station and place the material on the clamp transfer and positioning mechanism 4. The clamp transfer and positioning mechanism 4 is installed on the frame 1. The clamp transfer and positioning mechanism 4 is used to receive the material grabbed by the loading mechanism 3 and convey the material to the film tearing station and the discharge station in sequence, wherein the discharge station is located above the external material conveying line. A film-tearing mechanism 5 is mounted on the frame 1 and located above the film-tearing station. It is used to tear off the auxiliary material on the material delivered to the film-tearing station, thereby removing the release film attached to the auxiliary material. A material-discharging mechanism 6 is mounted on the frame 1 and located above the material-discharging station. It is used to grab the material delivered to the material-discharging station and return it to the material conveyor line. A material-discharging flipping mechanism 7 is mounted on the frame 1 and located below the material-discharging flipping mechanism 6. This flipping mechanism is used to flip the material that the material-discharging mechanism 6 returns to the material conveyor line according to user needs. This function is optional and can be used by the user.

[0080] The film tearing and waste discharge machine provided by the present invention realizes the fully automatic completion of a series of actions such as loading, positioning, film tearing (multi-film cycle tearing), unloading, and flipping (optional) of materials such as mobile phones and tablet computers through the coordinated cooperation among the feed guide limiting mechanism 2, the loading mechanism 3, the clamp transfer and positioning mechanism 4, the film tearing mechanism 5, the unloading mechanism 6 and the discharge flipping mechanism 7, and efficiently realizes the automatic tearing off of at least one waste film sheet (i.e., release film) on the material, with high production efficiency, small error, high product yield, low labor cost, and can realize flipping and unloading as needed.

[0081] See also Figure 3 In one embodiment, the feed guide and limit mechanism 2 includes two oppositely disposed guide and limit bars 21 and a stop plate 22 disposed at the end between the two guide and limit bars 21. Width adjustment components 23 are disposed on the outside of each guide and limit bar 21. The width adjustment components 23 drive the corresponding guide and limit bar 21 away from or toward the other guide and limit bar 21, thereby adjusting the spacing between the two guide and limit bars 21 according to the width of the material, thereby improving the versatility of the equipment. In addition, a feed position detection component is disposed at the end of each guide and limit bar 21. The feed position detection component can sense whether the material has arrived at the loading station. When the feed position detection component senses that the material has arrived at the loading station, it notifies the loading mechanism 3 to come and pick up the material.

[0082] See also Figure 3In one embodiment, the loading mechanism 3 includes a loading suction cup assembly 31 for grabbing materials and a loading lifting assembly 32 for driving the loading suction cup assembly 31 to move up and down. The loading lifting assembly 32 is fixed to the frame 1, and the lifting end of the loading lifting assembly 32 is fixed to the loading suction cup assembly 31. The unloading mechanism 6 includes a unloading suction cup assembly 61 for grabbing materials and a unloading lifting assembly 62 for driving the unloading suction cup assembly 61 to move up and down. The unloading lifting assembly 62 is fixed to the frame 1, and the lifting end of the unloading lifting assembly 62 is fixed to the unloading suction cup assembly 61. When the material arrives at the loading station, the loading lifting assembly 32 drives the loading suction cup assembly 31 to move down to pick up the material, and then the loading lifting assembly 32 drives the loading suction cup assembly 31 to move up and back to its original position. When the clamp assembly 41 of the clamp transfer and positioning mechanism 4 moves to the bottom of the loading suction cup assembly 31, the loading lifting assembly 32 drives the loading suction cup assembly 31 to move down and the loading suction cup assembly 31 releases the material, thereby placing the material on the clamp assembly 41 of the clamp transfer and positioning mechanism 4. When the clamp assembly 41 of the clamp transfer and positioning mechanism 4 transports the film-torn material to the unloading station, the unloading lifting assembly 62 drives the unloading suction cup assembly 61 to move down to pick up the material, and then the unloading lifting assembly 62 drives the unloading suction cup assembly 61 to move up and back to its original position. After the clamp assembly 41 of the clamp transfer and positioning mechanism 4 is removed from the unloading station, the unloading suction cup assembly 61 directly releases the film-torn material, allowing the material to fall back to the material conveying line under the action of gravity. Among them, the loading lifting component 32 and the unloading lifting component 62 both use stepper brake motors to drive the loading suction cup component 31 and the unloading suction cup component 61 to move up and down to realize CNC material picking, unloading, and unloading positioning control, and have a simple structure, small space occupation, and low production cost.

[0083] See also Figure 3 In one embodiment, the discharge flipping mechanism 7 includes a discharge collision rod 71 and a collision rod telescopic assembly 72 for extending or retracting the discharge collision rod 71. The collision rod telescopic assembly 72 is fixed to the frame 1, and the telescopic end of the collision rod telescopic assembly 72 is fixed to the discharge collision rod 71. Since the discharge mechanism 6 uses a loosening and direct dropping method to put the torn film material back onto the material conveying line, if the user needs to flip the material, the discharge collision rod 71 is extended into the material dropping path through the collision rod telescopic assembly 72. One side of the material hits the discharge collision rod 71 during the falling process and will flip and fall onto the material conveying line. At the same time, a buffer sleeve can be put on the discharge collision rod 71 to reduce the collision between the material and the discharge collision rod 71. The above-mentioned discharge flipping mechanism 7 has a simple structure and can realize material flipping during the material falling process without affecting the material discharge speed.

[0084] See also Figure 2 、 Figure 4In one embodiment, the fixture transfer and positioning mechanism 4 includes a fixture assembly 41 for clamping the material, an X-axis moving assembly 42 for driving the fixture assembly 41 along the X-axis, and a Y-axis moving assembly 43 for driving the fixture assembly 41 along the Y-axis. The Y-axis moving assembly 43 is fixed to the frame 1, and the movable end of the Y-axis moving assembly 43 is fixed to the X-axis moving assembly 42, while the movable end of the X-axis moving assembly 42 is fixed to the fixture assembly 41. The fixture transfer and positioning mechanism 4 receives the material grasped by the loading mechanism 3 through the fixture assembly 41, the X-axis moving assembly 42, and the Y-axis moving assembly 43, and sequentially transports the material to the film tearing station and the unloading station. After the feeding mechanism 3 grabs the material, the X-axis moving component 42 cooperates with the Y-axis moving component 43 to move the clamp component 41 to the bottom of the feeding mechanism 3. After the feeding mechanism 3 places the material on the clamp component 41, the clamp component 41 clamps the material, and then the X-axis moving component 42 cooperates with the Y-axis moving component 43 to move the clamp component 41 to the film tearing station, so that the auxiliary material on the material is positioned just below the mucous membrane end of the film tearing mechanism 5, and then wait for the film tearing mechanism 5 to tear off the release film on the auxiliary material; if there are multiple auxiliary materials that need to be torn off on the material, each auxiliary material needs to be positioned once, and each time the film tearing mechanism 5 is positioned, the release film on the corresponding auxiliary material will be torn off, thereby realizing multi-film cycle tearing; after the auxiliary material on the material is torn off, the X-axis moving component 42 cooperates with the Y-axis moving component 43 to move the clamp component 41 to the unloading station, waiting for the unloading mechanism 6 to grab it.

[0085] See also Figure 5 、 Figure 6 In one embodiment, the clamp assembly 41 has a flat structure and includes a clamp fixing plate 411, a front clamping block 412 slidably disposed on the clamp fixing plate 411, a rear clamping block 413 slidably disposed on the clamp fixing plate 411, and a clamping block driving assembly. The clamping block driving assembly is used to drive the front clamping block 412 and the rear clamping block 413 to slide toward or away from each other on the clamp fixing plate 411 to clamp or release the material. Specifically, when the front clamping block 412 and the rear clamping block 413 clamp the material, they respectively clamp the front and rear sides of the material. The clamp assembly 41 adopts a flat structural design, which is light and thin, reduces invalid travel, and effectively improves the operating efficiency of the equipment.

[0086] See also Figure 5 、 Figure 6Specifically, the clamping block driving assembly includes a clamping cylinder 414, a bearing push rod 415, a front push plate 416 and a rear push plate 417. The clamping cylinder 414 is fixed to one side of the clamp fixing plate 411 along the X-axis. One end of the bearing push rod 415 is fixed to the telescopic end of the clamping cylinder 414. The bottom of the other end of the bearing push rod 415 corresponds to the position of the front push plate 416 and the rear push plate 417. A front push roller 4151 and a rear push roller 4152 are respectively provided. The front push plate 416 and the rear push plate 417 are both slidably arranged on the clamp fixing plate 411 along the Y-axis direction. The front clamping block 412 and the rear clamping block 413 are respectively fixed to the front push plate 416 And on the rear push plate 417, the end of the front push plate 416 close to the bearing push rod 415 is provided with an inclined front roller groove 4161, the front push roller 4151 is located in the front roller groove 4161 and can slide along the front roller groove 4161, and the end of the rear push plate 417 close to the bearing push rod 415 is provided with an inclined rear roller groove 4171, the rear push roller 4152 is located in the rear roller groove 4171 and can slide along the rear roller groove 4171, and the inclination direction of the front roller groove 4161 is opposite to the inclination direction of the rear roller groove 4171, such as the front roller groove 4161 is inclined forward and the rear roller groove 4171 is inclined backward. When the clamping cylinder 414 extends the bearing push rod 415, the bearing push rod 415 drives the front push roller 4151 and the rear push roller 4152 to slide along the front roller slot 4161 and the rear roller slot 4171, respectively. Since the inclination direction of the front roller slot 4161 is opposite to the inclination direction of the rear roller slot 4171, the front push plate 416 slides forward and the rear push plate 417 slides backward. At this time, the front clamping block 412 and the rear clamping block 413 move away from each other, releasing the material on the clamp fixing plate 411. Conversely, when the clamping cylinder 414 retracts the bearing push rod 415, the front clamping block 412 and the rear clamping block 413 move toward each other, clamping the material on the clamp fixing plate 411. The above-mentioned clamping block drive assembly adopts an ultra-thin bidirectional synchronous roller push plate design, which has a unique structure, is compact and simple, is universal in size, clamps quickly and stably, and is easy to change.

[0087] See also Figure 5 Furthermore, the clamp fixing plate 411 is provided with a front push plate slot 4111 for the front push plate 416 to slide along the Y-axis direction and a rear push plate slot 4112 for the rear push plate 417 to slide along the Y-axis direction. The top surfaces of the front push plate 416 and the rear push plate 417 are flush with the top surface of the clamp fixing plate 411, thereby ensuring that the material can be placed stably on the clamp fixing plate 411, and also making the clamping of the front clamp block 412 and the rear clamp block 413 more stable.

[0088] See also Figure 5Furthermore, multiple sets of horizontal auxiliary rollers 4113 are provided on the left and right inner walls of the front push plate slide 4111 and the rear push plate slide 4112 to reduce the friction between the front push plate 416 and the front push plate slide 4111, and between the rear push plate 417 and the rear push plate slide 4112, so that the front push plate 416 and the rear push plate slide 4117 can slide smoothly back and forth along the front push plate slide 4111 and the rear push plate slide 4112.

[0089] See also Figure 5 Furthermore, the end of the front push plate 416 away from the bearing push rod 415 is provided with at least two long first adjustment grooves 4162 distributed side by side along the X-axis, and the bottom of the front clamping block 412 is provided with at least two first fixing holes 4121 that cooperate with the first adjustment grooves 4162. The first adjustment grooves 4162 and the corresponding first fixing holes 4121 cooperate with the fixing parts to fix the front clamping block 412 on the front push plate 416. By loosening the fixing parts, the position of the front clamping block 412 on the front push plate 416 can be adjusted, thereby adjusting the distance between the front clamping block 412 and the rear clamping block 413. The adjustment range is the length of the first adjustment groove 4162. At least two second, elongated adjustment slots 4172 are disposed at one end of the rear push plate 417, distal from the bearing push rod 415, and arranged side by side along the X-axis. The bottom of the rear clamping block 413 is provided with at least two second fixing holes 4131 that mate with the second adjustment slots 4172. The second adjustment slots 4172 and corresponding second fixing holes 4131 cooperate with fixings to secure the rear clamping block 413 to the rear push plate 417. By loosening the fixings, the position of the rear clamping block 413 on the rear push plate 417 can be adjusted, thereby adjusting the spacing between the front and rear clamping blocks 412 and 413 within the length of the second adjustment slots 4172. The arrangement of the first adjustment slots 4162, the second adjustment slots 4172, the first fixing holes 4121, and the second fixing holes 4131 allows for rapid adjustment of the spacing between the front and rear clamping blocks 412 and 413 according to the width of the material, thereby accommodating materials of various sizes and facilitating the replacement of the front and rear clamping blocks 412 and 413.

[0090] See also Figure 6 Furthermore, a front buffer bar 4122 is provided on the side of the front clamping block 412 near the rear clamping block 413, and a rear buffer bar 4132 is provided on the side of the rear clamping block 413 near the front clamping block 412, to prevent the front clamping block 412 and the rear clamping block 413 from damaging the material. At the same time, a first inclined surface 4123 is provided on the side of the front buffer bar 4122 near the rear clamping block 413, and the angle between the first inclined surface 4123 and the bottom surface of the front buffer bar 4122 is obtuse. A second downwardly inclined surface 4133 is provided on the side of the rear buffer bar 4132 near the front clamping block 412, and the angle between the second inclined surface 4133 and the bottom surface of the rear buffer bar 4132 is obtuse. This ensures that when the front clamping block 412 and the rear clamping block 413 clamp the material, the material is pressed against the fixture fixing plate 411, making the clamping more stable.

[0091] See also Figure 6 Furthermore, a push rod fixing seat 418 is provided on the fixture fixing plate 411. The push rod fixing seat 418 surrounds the bearing push rod 415. The top of the end of the bearing push rod 415 away from the clamping cylinder 414 is provided with a first limiting guide rod 4153 and a second limiting guide rod 4154 at positions corresponding to the front pushing roller 4151 and the rear pushing roller 4152, respectively. The first limiting guide rod 4153 and the second limiting guide rod 4154 are both perpendicular to the bearing push rod 415. A first guide rod slot 4181 and a second guide rod slot 4182 are provided at the top of the push rod holder 418, corresponding to the first limiting guide rod 4153 and the second limiting guide rod 4154, respectively. The top of the first limiting guide rod 4153 is located in the first guide rod slot 4181 and can slide left and right along the first guide rod slot 4181. The top of the second limiting guide rod 4154 is located in the second guide rod slot 4182 and can slide left and right along the second guide rod slot 4182. The arrangement of the push rod holder 418, the first limiting guide rod 4153, and the second limiting guide rod 4154 can make the extension and retraction of the bearing push rod 415 more stable.

[0092] See also Figure 6 Furthermore, a connector 4114 is provided at the rear end of the fixture fixing plate 411, through which the fixture fixing plate 411 is fixed to the movable end of the X-axis moving assembly 42. At the same time, an X-axis slider 4115 is provided at the rear end of the fixture fixing plate 411, and an X-axis slide rail is provided on the X-axis moving assembly 42 to be slidably connected to the X-axis slider 4115. The X-axis slider 4115 and the X-axis slide rail enable the X-axis moving assembly 42 to smoothly drive the fixture fixing plate 411 to move along the X-axis direction.

[0093] See also Figure 2 、 Figure 3 Furthermore, a clamp support roller assembly 44 is provided at the film tearing station. The clamp support roller assembly 44 includes a clamp support platform 441 fixed to the frame 1. A plurality of support rollers 442 are provided on the surface of the clamp support platform 441. When the clamp assembly 41 moves to the film tearing station, the support rollers 442 can effectively support the clamp assembly 41, preventing the clamp assembly 41 from deforming during the film tearing process. At the same time, since the friction between the support rollers 442 and the clamp assembly 41 is very small, it will not affect the movement of the clamp assembly 41.

[0094] See also Figure 7 、 Figure 8In one embodiment, the film tearing mechanism 5 includes a tape material tray assembly 51, a tape tensioning assembly 52, a pneumatic film tearing assembly 53, a tape winding assembly 54, a tape taking-up assembly 55 and a Z-axis moving assembly 56. The tape material tray assembly 51, the tape tensioning assembly 52, the pneumatic film tearing assembly 53, the tape winding assembly 54, and the tape taking-up assembly 55 are all fixed to the movable end of the Z-axis moving assembly 56. The tape tray assembly 51 stores adhesive tape 57 for film application. Adhesive tape 57 is common, transparent tape. The tape tensioning assembly 52 controls the tension of tape 57. The pneumatic film application assembly 53 applies the film application. The tape reel assembly 54 provides the power for the tape travel. The tape take-up assembly 55 recovers waste film. The Z-axis movement assembly 56 primarily drives the pneumatic film application assembly 53 up and down to facilitate film application and tearing operations. Adhesive tape 57 is pulled from the tape tray assembly 51, passes sequentially through the tape tensioning assembly 52, the pneumatic film application assembly 53, and the tape reel assembly 54, before being reeled into the tape take-up assembly 55. The pneumatic film application assembly 53 is positioned below the tape 57 tensioner and the tape reel assembly 54. The bottom of the pneumatic film application assembly 53 forms the film application end, where the tape 57 passes. During film tearing, the Z-axis moving assembly 56 drives the film end of the pneumatic film sticking assembly 53 downward to press against the auxiliary material being delivered to the film tearing station, causing the tape 57 to adhere to the release film of the auxiliary material on the material. The Z-axis moving assembly 56 then drives the film end of the pneumatic film sticking assembly 53 upward, thereby tearing off the release film from the auxiliary material via the tape 57. The film tearing mechanism 5, through the coordination of the tape tray assembly 51, the tape tensioning assembly 52, the pneumatic film sticking assembly 53, the tape winding assembly 54, the tape take-up assembly 55, and the Z-axis moving assembly 56, fully automatically completes a series of operations including tape feeding, film sticking, film tearing, and waste film recycling. Using common transparent tape to adhere the release film to the auxiliary material, it has the advantages of low cost, stable and efficient film tearing, and high product yield.

[0095] See also Figure 8 、 Figure 9In one embodiment, the pneumatic membrane assembly 53 includes a main body 531 and a membrane pressing block assembly 532 detachably mounted at the bottom of the main body 531. The membrane pressing block assembly 532 is adapted to accommodate smaller release films. Specifically, the membrane pressing block assembly 532 includes a plurality of membrane pressing blocks 5321 arranged side by side at the bottom of the main body 531, and two guide plates 5322 positioned on either side of the membrane pressing blocks 5321. A downward-facing guide cylinder 5323 is positioned above the two guide plates 5322. The guide cylinder 5323 is fixed to the main body 531, and the telescopic end of the guide cylinder 5323 is connected to the top of the two guide plates 5322. During tape running, the tape guide cylinder 5323 extends the two tape guide plates 5322 so that the bottom surfaces of the two tape guide plates 5322 are lower than the bottom surfaces of the mucosal pressure block 5321, thereby preventing the adhesive tape 57 from contacting the bottom surfaces of the mucosal pressure block 5321 during tape running. Since the bottom of the mucosal pressure block 5321 is a pressing end, and its material is generally silicone, if the adhesive tape 57 contacts it during tape running, it will affect the running of the adhesive tape 57 and easily cause damage to the pressing end of the mucosal pressure block 5321; when tearing the film, the tape guide cylinder 5323 retracts the two tape guide plates 5322 so that the bottom surfaces of the two tape guide plates 5322 are higher than the bottom surfaces of the mucosal pressure block 5321, so that the mucosal pressure block 5321 can drive the adhesive tape 57 to press against the release film on the material.

[0096] It should be noted that the number of mucosal pressing blocks 5321 is set according to the size of the release film on the material. Generally speaking, for a micro film, one mucosal pressing block 5321 is set, and for a slightly larger small film, two side-by-side mucosal pressing blocks 5321 can be set to increase the pressing area.

[0097] See also Figure 9 Furthermore, the bottom surfaces of the two guide plates 5322 are both spherical, which can make the tape 57 run more smoothly and avoid scratching the tape 57 during the extension process.

[0098] See also Figure 9 Furthermore, an adjusting rail 5311 is provided at the bottom of the main body 531, and an adjusting groove 53211 matching the adjusting rail 5311 is provided at the top of the mucosa pressure block 5321. Openings for the adjusting rail 5311 to enter are provided at the front and rear ends of the adjusting groove 53211. Through the setting of the above-mentioned adjusting rail 5311 and the adjusting groove 53211, the mucosa pressure block 5321 can be quickly disassembled and assembled, and the position of the mucosa pressure block 5321 can be adjusted.

[0099] See also Figure 10 、 Figure 11In another embodiment, the pneumatic mucosal liner assembly 53 includes a main body 531 and a mucosal liner roller assembly 533 detachably mounted at the bottom of the main body 531. The mucosal liner roller assembly 533 is adapted for larger release films and requires translational movement of the clamp assembly 41 to remove larger release films. Specifically, the mucosal liner roller assembly 533 includes a mucosal liner roller 5331 and two connecting plates 5332, respectively mounted on the front and rear sides of the mucosal liner roller 5331. Both connecting plates 5332 are secured to the front and rear sides of the bottom of the main body 531 by screws. By unscrewing the screws, the mucosal liner roller assembly 533 can be quickly removed from the main body 531, allowing the mucosal liner pressing block assembly 532 to be replaced with a smaller release film. When using the mucosal roller assembly 533 to tear off a larger release film, the Z-axis moving assembly 56 drives the mucosal roller assembly 533 to move downward, and the mucosal roller 5331 drives the tape 57 to press toward one end of the release film. After the tape 57 sticks to the release film, the X-axis moving assembly 42 of the clamp transfer and positioning mechanism 4 drives the clamp assembly 41 to move horizontally together with the material, so that the mucosal roller 5331 rolls from one end of the release film to the other end. During the rolling process, the mucosal roller 5331 gradually tears the release film from the auxiliary material.

[0100] See also Figure 10 In one embodiment, the film tearing mechanism 5 also includes a fixed side plate 58, which is fixed to the frame 1, and the Z-axis moving component 56 is fixed on the fixed side plate 58.

The Z-axis moving component 56 drives the tape material tray assembly 51, the tape tensioning assembly 52, the pneumatic mucofilm assembly 53, the tape winding assembly 54, and the tape taking-up assembly 55 to move up and down synchronously through the lifting bracket 561. Among them, the upper limit photoelectric detection sensor 581, the origin photoelectric detection sensor 582 and the lower limit photoelectric detection sensor 583 are arranged on the fixed side plate 58 in sequence from top to bottom, and the movable end of the Z-axis moving component 56 is provided with a detection component 562 that cooperates with the upper limit photoelectric detection sensor 581, the origin photoelectric detection sensor 582 and the lower limit photoelectric detection sensor 583. In the initial state, the detection component 562 is located in the detection area of ​​the origin photoelectric detection sensor 582. The upper limit photoelectric detection sensor 581 and the lower limit photoelectric detection sensor 583 are respectively used to control the highest upward position and the lowest downward position of the Z-axis moving component 56 to avoid the pneumatic mucosa component 53 from crushing the material.

[0101] See also Figure 10In one embodiment, the tape assembly 54 includes a tape roller 541 and a tape motor 542. The tape motor 542 is disposed within a lifting bracket 561. The tape roller 541 is disposed in front of the lifting bracket 561. One end of the tape roller 541 is connected to the output shaft of the tape motor 542, so that the tape motor 542 drives the tape roller 541 to rotate, providing power for the tape 57. The tape take-up assembly 55 includes a tape take-up roller 551, which is disposed in front of the lifting bracket 561. The tape take-up roller 551 is connected to the output shaft of the tape motor 542 via a synchronous belt assembly 552, so that a single power source drives the rotation of the tape roller 541 and the tape take-up roller 551, simplifying the control system.

[0102] See also Figure 7 In one embodiment, a tape shortage detection sensor 59 is provided between the tape material tray assembly 51 and the tape tensioning assembly 52. ​​The detection end of the tape shortage detection sensor 59 is directed toward the passing tape 57.
