Description

Technical Field

[0001] The present application relates to the field of industrial automation technology, and in particular to a film screen printing and tearing loading and unloading device. Background Art

[0002] In traditional production processes, operators are required to perform repetitive film-tearing movements for extended periods of time. This intense physical labor not only easily leads to fatigue but can also cause long-term health problems such as musculoskeletal injuries. Furthermore, new employees, lacking experience, often need time to familiarize themselves with the operating procedures, making it difficult to guarantee production efficiency and product quality during this period. In some cases, improper operation can even cause accidental injury to operators, increasing safety management risks for the company.

[0003] Film screen printing plates are a crucial component in the display manufacturing industry. However, due to the unique nature of these materials, they require a protective film to protect their surface. Before silkscreen printing, the protective film must be removed and the plates placed in other processing equipment. This product is designed to address the challenges associated with periodic manual film removal, such as operator fatigue and new employee inexperience. These issues often lead to low production efficiency, inconsistent product quality, significant material loss during production, and potential harm to operators. Utility Model Content

[0004] In view of this, the purpose of the embodiments of the present application is to provide a film screen printing tearing loading and unloading equipment to improve the problems existing in the prior art such as low manual operation efficiency, unstable production yield, large material loss and physical harm to operators.

[0005] The film screen printing tearing and loading and unloading equipment includes: a tearing mechanism, a conveying mechanism and a collecting mechanism; the tearing mechanism is used to remove the protective film attached to the items, and place the removed protective film on the protective film collecting component; the conveying mechanism is used to place the items with the protective film not removed on the tearing mechanism, and place the items that have undergone at least one protective film removal process on the collecting mechanism; the collecting mechanism includes: a qualified product collection component and an unqualified product collection component; wherein, the qualified product collection component is used to collect items with the protective film successfully removed; the unqualified product collection component is used to collect items with the protective film not successfully removed.

[0006] In the above implementation process, the film-tearing mechanism, the transport mechanism, and the collection mechanism work together. The film-tearing mechanism automatically removes the protective film, and the transport mechanism places the unteared items onto the film-tearing mechanism. The unteared items are then transported to the collection mechanism. The collection mechanism is divided into two parts: a qualified product collection component and a rejected product collection component, which collect successfully and unsuccessfully torn products, respectively. This achieves the automatic removal of the protective film from items and the transport and classified collection of items, reducing manual operations and improving production efficiency and operational safety.

[0007] Optionally, the film tearing mechanism includes: a first servo module and a film tearing assembly; a guide rail is provided on the first servo module, and the film tearing assembly is fixed on the guide rail; the film tearing assembly includes: a rubber-coated wheel and a lifting cylinder; the rubber-coated wheel is provided with glue, and the lifting cylinder drives the film tearing assembly to move toward the direction where the object is located until the glue on the rubber-coated wheel contacts the protective film of the object; when the protective film contacts the rubber-coated wheel, the lifting cylinder moves the rubber-coated wheel in a direction away from the object to separate the object and the protective film.

[0008] In the above implementation process, a film tearing assembly is fixed on the guide rail of the first servo module. The assembly has a rubber-coated wheel with adhesive that can be raised and lowered, which is used to pick up and tear off the protective film. The coordinated action of the rubber-coated wheel and the lifting cylinder realizes the separation of the protective film from the object. The rubber-coated wheel in the film tearing assembly is designed with adhesive that can adhere firmly to the protective film. When the lifting cylinder drives the film tearing assembly to move, the adhesive on the rubber-coated wheel contacts and adheres to the protective film. Then the cylinder drives the rubber-coated wheel to move in a direction away from the object, realizing the separation of the protective film from the object. This process reduces physical damage to the object while improving the efficiency of film tearing.

[0009] Optionally, the protective film collecting assembly includes a first clamping cylinder, a second clamping cylinder and a protective film collecting bin; wherein, in the direction of gravity, the second clamping cylinder is arranged opposite to the protective film collecting bin; the first clamping cylinder is configured to move along the guide rail direction on the first servo module to above the second clamping cylinder while clamping the separated protective film; the second clamping cylinder is configured to clamp the protective film when the first clamping cylinder moves to the second clamping cylinder; the second clamping cylinder is also configured to continue clamping the protective film until the first clamping cylinder releases the protective film; and release the clamping of the protective film after the first clamping cylinder releases the protective film; the protective film collecting bin is configured to receive the protective film released by the second clamping cylinder.

[0010] During the above implementation process, the first clamping cylinder moves along the guide rail to above the second clamping cylinder. The torn protective film is clamped by the first clamping cylinder and moved above the second clamping cylinder. The second clamping cylinder takes over the protective film and places it in the collection bin. The second clamping cylinder is set directly opposite the protective film collection bin. When the first clamping cylinder moves above it, the second clamping cylinder takes over the protective film and continues to clamp it until the first clamping cylinder releases the protective film. Subsequently, the second clamping cylinder places the protective film in the collection bin and releases its grip on the protective film. This design ensures the smooth transfer and safe placement of the protective film, allowing the protective film to be effectively collected and facilitated for subsequent processing and recycling.

[0011] Optionally, the protective film collecting assembly further includes a first sensor; the first sensor is arranged toward the inner edge of the protective film collecting assembly; the first sensor is configured to detect whether the protective film collecting assembly has collected the protective film based on scanning the inner edge of the protective film collecting assembly.

[0012] In this implementation, the first sensor scans the inner edge of the protective film collection assembly to detect whether the protective film has been collected. This sensor enables real-time monitoring of the protective film within the collection assembly, promptly notifying the operator whether the protective film has been removed from an item, improving collection efficiency and accuracy.

The positioning module ensures that the unloading and picking arm can accurately locate the position of the items after the film is torn off, thereby improving the accuracy of handling. The design of the loading and unloading arms enables the handling mechanism to flexibly handle items of different sizes and shapes, increasing the applicability of the equipment. The automated handling process ensures continuity from film tearing to collection, reduces production interruptions, and improves the overall efficiency of the production line.

[0015] Optionally, the second servo module includes a segmented slide rail; the segmented slide rail includes: a first slide rail and a second slide rail; the loading suction cup assembly is slidably connected to the first slide rail; the first slide rail is configured to guide the loading suction cup assembly to move toward the film tearing mechanism to place the item on the film tearing mechanism; the unloading suction cup assembly is slidably connected to the second slide rail; the second slide rail is configured to guide the unloading suction cup assembly to move toward the collection mechanism to place the item on the collection mechanism; wherein, the unloading suction cup assembly places qualified products on the qualified product collection assembly, and places unqualified products on the unqualified product collection assembly.

[0016] In this implementation, the second servo module's segmented slide rail design enables the loading and unloading suction cup assemblies to move along a predetermined trajectory. The first slide rail guides the items to the film removal mechanism, while the second slide rail guides the removed items to the collection mechanism.

[0018] In this implementation, the reject collection component, through its design of guide rails and collection boxes, and the counting function of a counter, automatically collects and monitors rejects, triggering an alarm when a certain number of rejects is reached. This automatic collection and counting of rejects helps quickly identify production issues, allowing for timely adjustments to production strategies and improving product quality.

[0019] Optionally, the collection mechanism also includes: a storage device transmission assembly; the storage device transmission assembly includes: a storage device guide sheet metal, a storage device, a ruler inserting cylinder and a first conveyor belt; the storage device is arranged in the middle of the storage device guide sheet metal; the ruler inserting cylinder is used to separate the storage device; the first conveyor belt moves along a first direction to transmit the storage device to the qualified product collection assembly; wherein, the first direction is parallel to the support surface of the film silk screen tearing loading and unloading equipment and perpendicular to the direction of the second servo module.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the embodiments of the present application.

[0038] The present application embodiment provides a film screen printing tearing film loading and unloading device, see Figure 1 , Figure 1The internal device diagram of the film screen printing tearing and loading and unloading equipment provided in the embodiment of the present application, the tearing mechanism 110 is used to remove the protective film attached to the article, and place the removed protective film on the protective film collecting component 120; the conveying mechanism 200 is used to place the articles with the protective film not removed on the tearing mechanism 110, and place the articles that have undergone the protective film removal process at least once on the collecting mechanism; the collecting mechanism includes: a qualified product collection component 330 and an unqualified product collection component 310; wherein, the qualified product collection component 330 is used to collect articles with the protective film successfully removed; the unqualified product collection component 310 is used to collect articles with the protective film not successfully removed.

[0039] After the system is powered on and the processing program is confirmed to be correct, the stacked items that need to be peeled off are manually placed on the item loading assembly 130. After the equipment is started and the automatic operation program is turned on, the conveying mechanism 200 performs the conveying operation, takes the items from the item loading assembly 130, places them on the peeling platform assembly 140 for positioning, and then the peeling mechanism 110 peels off the protective film on the surface of the product and places the protective film into the protective film collection assembly 120; the conveying mechanism 200 will place the unqualified products (items whose protective film has not been successfully removed) on the unqualified product collection assembly 310; the storage device transmission assembly 320 transfers the storage device 322 to the qualified product collection assembly 330 to receive the qualified products (items whose protective film has been successfully removed) conveyed by the conveying mechanism 200. The equipment is connected to the downstream equipment (not shown in the figure) and finally circulates the qualified products (items whose protective film has been successfully removed) to the downstream equipment; each component operates simultaneously without interfering with each other, and the above actions are repeated.

[0040] In the above implementation process, the film-tearing mechanism 110, the conveying mechanism 200, and the collection mechanism (qualified product collection component 330 and unqualified product collection component 310) work together. The film-tearing mechanism 110 removes the protective film through automatic control, and places the untorn items on the film-tearing mechanism through the conveying mechanism 200. The torn items are then transported to the collection mechanism. The collection mechanism collects successful and unsuccessful film-tearing products respectively. The automatic tearing off of the protective film on the items and the transportation and classified collection of the items are realized, which reduces manual operation and improves production efficiency and work safety. In addition, the equipment symmetrically arranges two sets of identical facilities, which can complete mechanical operations more efficiently.

[0041] In one embodiment of the present application, the article is a film silk-screen plate, and the film tearing mechanism 110 removes the protective film attached to the film silk-screen plate through automatic control, and places the film silk-screen plate that has not been torn off onto the film tearing mechanism 110 through the conveying mechanism 200. The film silk-screen plate after tearing off is conveyed to the collection mechanism (qualified product collection component 330 and unqualified product collection component 310).

[0042] Specifically, see Figure 2 , Figure 2 This is a schematic diagram of the film tearing mechanism in the film screen printing film tearing loading and unloading equipment provided in an embodiment of the present application. The film tearing mechanism 110 includes: a first servo module 116 and a film tearing assembly; a guide rail is provided on the first servo module 116, and the film tearing assembly is fixed to the guide rail; the first servo module 116 drives the various components to move forward and backward.

[0043] The film tearing assembly includes: a rubber wheel 111, a stop cylinder 112, a caliper 113, a lifting cylinder 114, and a driving assembly 115; the driving assembly 115 can control the actions of each cylinder; the rubber wheel 111 is provided with glue, and the lifting cylinder 114 drives the film tearing assembly as a whole to move toward the direction where the object is located until the glue on the rubber wheel 111 contacts the protective film of the object, so that the stickiness of the glue surface sticks to the protective film of the object, and then the stop cylinder 112 fixes the rubber wheel 111 to prevent the rubber wheel from rolling and causing the protective film to fall off; when the protective film is in contact with the rubber wheel, the lifting cylinder 114 moves the rubber wheel 111 away from the object to separate the object and the protective film. When the rubber-coated wheel rises to a predetermined position, the driving assembly 115 controls the first clamping cylinder 121 to clamp the protective film to prevent it from falling off again. Then the first servo module 116 moves toward the direction close to the protective film collecting assembly 120, so that the protective film on the surface of the object can be completely torn off; the rubber-coated wheel 111 can be quickly replaced by fixing it with a caliper 113 (preferably a quick caliper).

[0044] In the above implementation, a film tearing assembly is fixed to the guide rail of the first servo module 116. This assembly utilizes a liftable, adhesive-coated wheel to lift and tear off the protective film. The rubber-coated wheel and the lifting cylinder work together to separate the protective film from the object. Precise control of the servo module and guide rail improves the accuracy and reliability of the film tearing process, reducing errors during the process.

[0045] Optionally, the adhesive can be rubber-based adhesive, acrylic-based adhesive, silicone adhesive, pressure-sensitive adhesive, water-based adhesive, or other adhesive suitable for different types of protective films; the driving mechanism can be a solenoid valve assembly, a servo motor controller, or other driver that can control the movement of the cylinder.

[0046] In one embodiment of the present application, the object is a film silk-screen plate, and the lifting cylinder 114 drives the film tearing assembly to move toward the direction of the film silk-screen plate until the glue on the rubber-coated wheel 111 contacts the protective film of the film silk-screen plate; when the protective film contacts the rubber-coated wheel 111, the lifting cylinder 114 moves the rubber-coated wheel 111 away from the film silk-screen plate to separate the protective film on the film silk-screen plate.

[0047] Combine Figure 2 The first clamping cylinder 121 and the first sensor 124 are shown in FIG. Figure 3 , Figure 3 Schematic diagram of the protective film collecting assembly in the film screen printing tearing loading and unloading equipment provided in an embodiment of the present application.

[0048] The protective film collecting assembly 120 includes a first clamping cylinder 121, a second clamping cylinder 122, a protective film collecting bin 123 and a first sensor 124; wherein, in the direction of gravity (i.e., the first direction), the second clamping cylinder 122 is arranged opposite to the protective film collecting bin 123; the first clamping cylinder 121 is configured to move to the top of the second clamping cylinder 122 along the guide rail direction of the first servo module 116 while clamping the separated protective film; the second clamping cylinder 122 is configured to clamp the protective film when the first clamping cylinder 121 moves onto the second clamping cylinder 122; and continue to clamp the protective film until the first clamping cylinder 121 releases the protective film; and release the clamping of the protective film after the first clamping cylinder 121 releases the protective film; at this time, the protective film will fall into the protective film collecting bin 123; the protective film collecting bin 123 is configured to receive the protective film released by the second clamping cylinder 122.

[0049] The protective film collecting assembly further includes a first sensor 124 ; the first sensor 124 is disposed toward the inner edge of the protective film collecting assembly; the first sensor 124 is configured to detect whether the protective film collecting assembly has collected the protective film based on scanning the inner edge of the protective film collecting assembly.

[0050] In the above implementation process, the first clamping cylinder 121 moves along the guide rail to above the second clamping cylinder 122. The protective film after tearing is clamped by the first clamping cylinder 121 and moved to above the second clamping cylinder 122. The second clamping cylinder 122 takes over the protective film and places the protective film into the protective film collection bin 123 to achieve effective collection of the protective film. The precise control of the cylinders (the first clamping cylinder 121 and the second clamping cylinder 122) ensures that the protective film can be accurately clamped and placed, thereby improving the success rate of collection. The first sensor 124 scans the inner edge of the protective film collection assembly 120 to detect whether the protective film is collected. The use of the sensor realizes real-time monitoring of the protective film in the collection assembly, and promptly informs the operator whether the protective film of the item has been torn off, thereby improving collection efficiency and accuracy.

[0051] Optionally, the first sensor 124 may be a photoelectric sensor, an optical fiber sensor, a visual sensor, a pressure sensor, a displacement sensor, or the like, which is capable of detecting whether the protective film is collected by the protective film collecting bin.

[0052] In addition, the items need to be pre-processed before tearing the film. For details, please refer to Figure 4 and Figure 5 ; Figure 4 This is a schematic diagram of the article loading component in the film screen printing tearing loading and unloading equipment provided in an embodiment of the present application. Figure 5 Schematic diagram of the film tearing platform assembly in the film screen printing film tearing loading and unloading equipment provided in an embodiment of the present application.

[0053] The operator places the items that need to be stripped on the support plate 133 of the item loading assembly 130, and manually adjusts the coarse positioning assembly 134 so that the items can be roughly placed at the specified position above the support plate 133; the support plate 133 is driven to move by the lead screw stepper motor 131, and the support plate 133 is fixed on the linear sleeve assembly 132 to realize vertical reciprocating movement up and down; when the support plate 133 drives the items to rise to the sensing range of the in-place detection photoelectric 136, the in-place detection photoelectric 136 sends a signal to stop the lead screw stepper motor 131 from driving the support plate 133 to rise, and control the first ion wind rod 135 to blow air. The purpose of blowing air at this stage is to eliminate static electricity and prevent product stacking; and feedback is fed back to the conveying mechanism 200 for material picking.

[0054] The film tearing mechanism also includes a film tearing platform assembly 140, which transports the preliminarily processed articles to the transport mechanism 200. Figure 5 The film tearing operation is performed on the film tearing platform assembly 140 shown. After the item reaches the vacuum adsorption platform 141, the precise positioning assembly 142 positions the item. The vacuum generator 143 then generates a vacuum, firmly adsorbing the item onto the vacuum adsorption platform 141. At this point, the second ion wind bar 144 begins blowing air to eliminate static electricity on the product surface and improve the success rate of the subsequent film tearing.

[0055] In the above implementation process, the pallet 133 is used to carry the items that need to be torn off, providing a stable platform for the operation; the coarse positioning component 134 allows the operator to manually adjust the approximate position of the item to ensure that the item can be correctly placed in the appropriate position above the pallet 133, reducing the difficulty of operation; the screw stepper motor 131 drives the pallet 133 to move vertically accurately to realize the loading process of the item; the linear sleeve component 132 supports the pallet 133 and ensures that it can move up and down smoothly; the in-position detection photoelectric 136 sends a signal to stop the motor drive when the item rises to the predetermined position, ensuring that the item is accurately positioned. The vacuum generator 143 ensures that the item is stably fixed during the tearing process, preventing the tearing failure or damage caused by the movement of the item; the automated and precise loading and positioning process reduces the preparation time before tearing off the film and improves the overall production efficiency.

[0056] In one embodiment of the present application, the operator places the film screen printing plate that needs to be peeled off on the support plate 133 of the film screen printing plate feed assembly, and manually adjusts the coarse positioning assembly 134 so that the film screen printing plate can be roughly placed at the specified position above the support plate 133; the support plate 133 is driven by the screw stepper motor 131 to move, and the support plate 133 is fixed on the linear sleeve assembly 132 to achieve vertical up and down reciprocating movement; when the support plate 133 drives the film screen printing plate to rise to the position, the induction of the detection photoelectric 136 is detected. Within the range, the in-position detection photoelectric 136 sends a signal to stop the screw stepper motor 131 from driving the support plate 133 to rise, and control the first ion wind rod 135 to blow air. The transport mechanism 200 transports the preliminarily processed items to the film tearing platform assembly 140 for film tearing operation. After the items arrive at the vacuum adsorption platform 141, the fine positioning assembly 142 positions the items, and the vacuum generator 143 will generate vacuum to firmly adsorb the items on the vacuum adsorption platform 141. At this time, the second ion wind rod 144 starts to blow air.

[0057] See Figure 6 , Figure 6 Schematic diagram of the transport mechanism in the film screen printing and tearing loading and unloading equipment provided in an embodiment of the present application.

[0058] The transport mechanism 200 includes a second servo module 210, a loading and picking arm 201 and a unloading and picking arm 202; one end of the second servo module 210 is connected to the loading and picking arm 201, and the other end of the second servo module 210 is connected to the unloading and picking arm 202; the end of the loading and picking arm 201 is connected to the loading suction cup assembly 203; the unloading and picking arm 202 is connected to the positioning module 205, and the end of the unloading and picking arm 202 is connected to the unloading suction cup assembly 204; the positioning module 205 is used to determine the moving position of the unloading and picking arm 202.

[0059] The second servo module 210 includes a segmented slide rail; the segmented slide rail includes: a first slide rail 211 and a second slide rail 212; the loading and picking arm 201 and the loading suction cup assembly 203 are slidably connected to the first slide rail 211; the first slide rail 211 is configured to guide the loading suction cup assembly to move toward the film tearing mechanism 110 to place the item on the film tearing mechanism 110; the unloading and picking arm 202 and the unloading suction cup assembly 204 are slidably connected to the second slide rail 212; the second slide rail 212 is configured to guide the unloading suction cup assembly to move toward the collection mechanism to place the item on the collection mechanism; wherein, the unloading suction cup assembly places qualified products on the qualified product collection assembly 330, and places unqualified products on the unqualified product collection assembly 310.

The loading and picking arm 201 is responsible for placing the items to be torn onto the film tearing platform assembly 140, and the unloading and picking arm 202 is responsible for placing the items after the film is torn onto the collection mechanism, thereby realizing the automated transport of the items from the state to be torn to the state after the film is torn and then transferred to the collection mechanism. The positioning module 205 ensures that the unloading and picking arm 202 can accurately locate the position of the items after the film is torn, thereby improving the accuracy of the transport. The design of the loading and unloading arms enables the transport mechanism to flexibly handle items of different sizes and shapes, increasing the applicability of the equipment. The automated transport process ensures continuity from film tearing to collection, reduces production interruptions, and improves the overall efficiency of the production line. The segmented slide rail design of the second servo module 210 enables the loading and unloading suction cup assemblies to move along a predetermined trajectory. The first slide rail 211 guides the items to the film removal mechanism, while the second slide rail 212 guides the removed items to the collection mechanism. This segmented slide rail design makes the handling process more flexible and precise, improving the equipment's space utilization and handling efficiency.

[0061] Optionally, the suction cup assembly can be equipped with a pressure regulating device, allowing the suction force to be adjusted according to the weight and surface characteristics of the object to avoid damaging the object; an integrated visual recognition system can be used to assist the positioning module 205 to improve placement accuracy by identifying the shape and position of the object.

[0062] As an example, a double-motor linear motor can be used with two independent motion components. The loading and picking arm 201 is fixed on one mover, and the loading suction cup assembly 203 is fixed under the arm. The main function is to remove the items from the item loading assembly 130 via the first slide rail 211 and place them on the film tearing platform assembly 140; the other mover is fixed on the unloading and picking arm 202. Due to the inconsistency of the unloading position, a positioning module 205 is provided to facilitate the adjustment of the final unloading position; the positioning module 205 is fixed on the unloading and picking arm 202, and the unloading suction cup assembly 204 is fixed under the arm. The main function is to place the items after film tearing into the collection mechanism via the second slide rail 212, that is, to place unqualified products into the unqualified product collection assembly 310, and to place qualified products into the qualified product collection assembly 330.

[0063] See Figure 7 , Figure 7 Schematic diagram of the defective product collection component in the film screen printing tearing loading and unloading equipment provided in an embodiment of the present application.

[0064] The defective product collection assembly includes: a guide rail 311, a defective product collection box 312 and a counter (not shown); the guide rail 311 is arranged along a first direction; the defective product collection box 312 is placed on the guide rail 311; the defective product collection box 312 is used to store defective products transported by the unloading suction cup assembly; the first direction is parallel to the support surface of the film screen printing and tearing loading and unloading equipment and perpendicular to the direction of the second servo module 210; the counter is set toward the inside of the defective product collection box 312; every time the defective product collection box 312 collects a defective product, the count is increased by 1, and when the count value reaches the set value, an alarm is issued through the alarm.

[0065] In the above implementation, guide rail 311 provides stable guidance and support for reject collection box 312, ensuring its stability and accuracy as it moves along a set direction. Through the structural design of the guide rail and collection box, as well as the counting function of the counter, reject collection assembly 310 automatically collects and monitors rejects, triggering an alarm when a certain number of rejects is reached. This automatic collection and counting of rejects helps quickly identify production issues, allowing for timely adjustments to production strategies and improving product quality.

[0066] See Figure 8 , Figure 8 Schematic diagram of the storage device transmission component in the film screen printing and tearing loading and unloading equipment provided in an embodiment of the present application.

[0067] The collection mechanism also includes: a storage device transmission assembly 320; the storage device transmission assembly 320 includes: a storage device guide sheet metal 321, a storage device 322, a ruler inserting cylinder 323 and a first conveyor belt 324; the storage device 322 is arranged in the middle of the storage device guide sheet metal 321; the ruler inserting cylinder 323 is used to separate the storage device 322; the first conveyor belt 324 moves along the first direction to transmit the storage device 322 to the qualified product collection assembly 330; wherein the first direction is parallel to the support surface of the film silk screen tearing loading and unloading equipment and perpendicular to the direction of the second servo module 210. The storage device transmission assembly 320 also includes: a first lifting motor 327 and a second sensor 325; the first lifting motor 327 is configured to lift the storage device 322 to a preset height; when the first lifting motor 327 lifts the storage device to the preset height, the inserting cylinder 323 separates the storage device 322 at the bottom; the second sensor 325 is fixed to the inner side of the storage device guide sheet metal; the second sensor is configured to detect whether there is a storage device above the storage device guide sheet metal based on scanning above the storage device guide sheet metal.

[0068] As an example, the operator places an empty storage device 322 in the middle of the storage device guide sheet metal 321, and the first lifting motor 327 lifts the entire stack of storage devices to a certain height. When only the height of the bottom storage device 322 is lower than the ruler cylinder 323, the ruler cylinder 323 extends to lift up all the storage devices 322 on the second to last layer and above; the first lifting motor 327 continues to descend until the bottom storage device 322 falls onto the first conveyor belt 324, and the first conveyor belt 324 is driven by the first conveyor belt speed control motor 326; the storage device transmission component is used to transfer the empty storage devices one by one to the qualified product collection component, and the second sensor 325 is used to detect whether there are more storage devices 322 above the storage device guide sheet metal 321. If there are no more storage devices 322, the equipment will alarm.

[0069] During the above implementation process, the storage device guide sheet metal 321 provides stable guidance and support for the storage device 322, ensuring that it maintains the correct position during transportation. The storage device 322 is used to store items after film removal for subsequent collection. The ruler cylinder 323 precisely controls the cylinder's movement to separate the storage devices 322 one by one, ensuring that only one storage device enters the conveyor belt at a time. The first conveyor belt 324 smoothly transports the storage devices 322 along a set direction to the qualified product collection assembly 330, realizing automated item handling. The second sensor 325 detects the storage devices 322 above the guide sheet metal, enabling real-time monitoring of the number of storage devices, improving the intelligence level of the system. The first lifting motor 327 assists in delivering the storage devices 322 one by one to the conveyor belt through lifting and lowering, realizing an automated loading process. The first lifting motor 327 and the second sensor 325 cooperate to realize the lifting and detection of the storage devices 322, ensuring the accurate positioning of the storage devices 322. At the same time, it ensures that the equipment will not operate in an unloaded state.

[0072] In the above implementation process, the second lifting motor 332 is responsible for driving the second conveyor belt 331 to perform lifting and lowering movements to realize the vertical movement of the storage device 322; the second conveyor belt 331 receives the storage device 322 from the first conveyor belt 324 and moves to a preset height under the drive of the second lifting motor 332; the positioning cylinder 333 is used to judge and control whether the storage device 322 has reached the specified upper and lower positions to ensure accurate vertical docking; the third conveyor belt 334 is responsible for moving in the horizontal direction to deliver the storage device 322 containing successfully torn film items to the downstream equipment; the third conveyor belt 334 is driven by the third conveyor belt speed control motor 337; the blocking cylinder 335 may be used to control the position of the storage device 322 on the third conveyor belt 334 or for emergency stop; the third sensor 336 is used to detect whether the storage device 322 has been completely removed from the horizontal conveyor device to ensure correct item counting and process control; the qualified product collection component realizes the automatic transportation of qualified products and docking with downstream equipment through the cooperation of the lifting transmission device and the horizontal transmission device, thereby improving the continuity and automation of the entire production process.
