Description

Technical Field

[0001] This invention relates to the field of laparoscopic protective sleeve production technology, specifically to a laparoscopic protective sleeve production equipment with material breakage detection. Background Technology

[0002] Medical endoscope protective sleeves are key protective consumables in the medical field to ensure the hygiene of robot operation and prevent cross-infection. They are widely used in clinical applications of medical equipment such as endoscopic surgical robots and thoracic and laparoscopic surgical robots. Their production process must meet the strict requirements of the pharmaceutical industry for cleanliness, continuity and product consistency.

[0003] Currently, the automated production of endoscopic protective sleeves mainly relies on continuous production lines of "film unwinding - thermal bonding - fixed-length sealing and cutting". Among them, the feeding module, as the core unit of film conveying, directly determines the overall production efficiency and product qualification rate through its operational stability. However, sleeve production equipment still has unresolved technical defects in practical applications in the pharmaceutical industry:

[0004] Firstly, the material loading process involves too much manual operation. The film rolls used in the production of medical endoscope protective sleeves are usually large in volume and heavy in weight. The entire loading and unloading process requires manual handling and placement, which is not only labor-intensive but also has low material replenishment efficiency.

[0005] Secondly, the material shortage monitoring lacks an automated feedback mechanism, requiring operators to monitor the film conveying status in real time. If the material shortage is not detected in time, it will cause the subsequent processing modules to run idle, which will not only delay the production progress but also generate ineffective processing losses, further reducing production efficiency.

[0006] Third, there are prominent safety hazards in operation. The material feeding area of ​​the existing equipment is adjacent to the operating conveyor system and processing module. When replenishing materials, operators need to work in a narrow space inside the equipment, which is not only inconvenient to operate, but also very easy to accidentally touch the high-speed rotating parts, causing human injury accidents and seriously threatening the personal safety of operators.

[0007] Fourth, fault tolerance capability: the feeding module of existing equipment is mostly equipped with a single motor. When the motor fails, the entire production line needs to be completely stopped for maintenance, which cannot achieve uninterrupted production, resulting in production plan delays and making it difficult to meet the stringent requirements of the pharmaceutical industry for production continuity.

[0008] Therefore, this invention proposes a production equipment for endoscope protective sleeves with material breakage detection. Summary of the Invention

[0009] The purpose of this invention is to provide a production equipment for endoscope protective sleeves with material breakage detection, so as to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a production equipment for endoscopic protective sleeves with material breakage detection, comprising a frame, a feeding module configured at the front end of the frame, and a sleeve forming and processing module configured at the rear end of the frame. A conveying system for conveying film is mounted on the frame. The feeding module includes two feeding rollers distributed vertically, each equipped with an independent drive assembly for independent rotation. The feeding module is equipped with a station switching mechanism, which drives the two feeding rollers to alternately switch to a feeding station adapted to the conveying system. Film is fed into the conveying system, and the feeding rollers not in the feeding station are in the waiting station. Each feeding roller is equipped with a deflection component, which drives the feeding roller to deflect horizontally away from the frame only when the corresponding feeding roller is in the waiting station, and performs a material replenishment operation on the feeding roller in the waiting station. When the corresponding feeding roller is in the feeding station, the deflection component is locked to maintain the adaptation state of the feeding roller with the conveying system. A detection module is set on the film conveying path of the conveying system, which is used to detect the material breakage state of the film conveying path.

[0011] Preferably, the workstation switching mechanism includes an arc-shaped guide positioning ring fixedly connected to the frame, an axe bar slidably connected inside the arc-shaped guide positioning ring, a drive motor for driving the axe bar to rotate is installed outside the frame, roller shaft steering positioning seats are rotatably assembled at both ends of the axe bar, and the feeding roller is rotatably connected inside the roller shaft steering positioning seats.

[0012] Preferably, a second drive motor is mounted on both sides of the axe bar. The second drive motor transmits power to the corresponding feeding roller through a gear structure. The gear structure can move with the switching of work positions to achieve selective engagement and disengagement of power.

[0013] Preferably, the gear structure includes two meshing driven bevel gears mounted on the surface of the roller shaft steering positioning seat, and a driving bevel gear fixedly connected to the second output end of the drive motor; one of the driven bevel gears is fixedly connected to the feeding roller, and the driving bevel gear and the driven bevel gear are normally meshed to transmit power. When the roller shaft steering positioning seat rotates with the work position switching action, the driven bevel gear on the corresponding side can separate from the driving bevel gear with the rotation of the roller shaft steering positioning seat, thereby releasing the meshing state between the two.

[0014] Preferably, both ends of the axe bar are provided with pivoting grooves, and the bottom of the roller shaft steering positioning seat is fixedly connected with a pivoting column. The pivoting column is rotatably adapted to the pivoting groove to realize the rotational connection between the axe bar and the roller shaft steering positioning seat.

[0015] Preferably, the pivoting mating column and the pivoting mating groove are respectively located on the outer region of the gear structure. When the corresponding feeding roller is in the waiting position, the pivoting mating column is located on the side away from the sleeve forming processing module, so as to drive the feeding roller to deflect horizontally away from the frame in conjunction with the deflection component.

[0016] Preferably, both the roller shaft steering positioning seat and the axe bar are equipped with locking components, which are used to selectively lock the rotational relationship between the roller shaft steering positioning seat and the axe bar.

[0017] Preferably, both the axe bar and the roller shaft steering positioning seat are provided with matching threaded holes, and the locking member is a bolt adapted to the threaded hole. By screwing the bolt into the corresponding threaded hole, the relative rotation between the roller shaft steering positioning seat and the axe bar can be locked.

[0018] Preferably, the rotation logic of the drive motor driving the axe blade is as follows: first, the axe blade is driven to rotate 180 degrees clockwise to complete one workstation switch, and then the axe blade is driven to rotate 180 degrees counterclockwise, thus achieving the alternating switching of the two feeding rollers in a cycle.

[0019] Preferably, the detection module is used to monitor the continuous conveying status of the film in real time and provide feedback on the material interruption signal. The detection module is connected to the station switching mechanism and the sleeve forming processing module respectively. When the detection module detects the material interruption, it triggers the station switching mechanism to start and switch the feeding roller, and at the same time triggers the sleeve forming processing module to pause operation. When the new feeding roller is switched into place, it triggers the sleeve forming processing module to resume operation. The sleeve forming processing module is used to process the film conveyed by the conveying system into a cavity mirror protective sleeve, and the operating status of the sleeve forming processing module is adapted to the conveying status of the conveying system.

[0020] Preferably, the detection module is a through-beam photoelectric sensor, with its transmitter and receiver located on opposite sides of the film conveying path to monitor the continuous passage of the film in real time.

[0021] Preferably, the sleeve forming processing module is a continuous forming mechanism including a heat sealing component and a sealing and cutting component. The sleeve forming processing module is arranged sequentially along the conveying direction of the conveying system and is used to heat press the film into a cylindrical structure and then seal and cut it to a fixed length to form a finished endoscope protective sleeve.

[0022] Preferably, the surface of the roller turning positioning seat is equipped with a limiting strip, the limiting strip and the surface of the axe bar are in contact, the limiting strip avoids the return angle deviation after the work station is switched, and ensures the matching accuracy between the feeding roller and the conveying system.

[0023] Preferably, the end of the feeding roller away from the roller shaft steering positioning seat is provided with a support platform driven by an external electric slide. The external electric slide drives the support platform to approach / move away from the feeding roller. When feeding or switching work positions, the support platform retracts and separates from the feeding roller. After the feeding roller stabilizes, the support platform extends and forms a rotatable connection with the end of the feeding roller.

[0024] Preferably, the wiring of the second drive motor is arranged through an external flexible chain. The external flexible chain is adapted to the 180-degree forward and reverse rotation trajectory of the axe bar and is used to store and protect the wiring to prevent the wiring from getting tangled or worn.

[0025] Preferably, the arc-shaped guide positioning ring is a split structure, which is divided into at least two parts, and the parts are detachably connected by fasteners so that the axe blade can be assembled into the internal sliding path of the arc-shaped guide positioning ring.

[0026] Preferably, the frame has a boss on its exterior, and the drive motor is fixedly mounted on the boss.

[0027] Preferably, in the two feeding rollers that are distributed vertically, the upper feeding roller corresponds to the feeding station, and the lower feeding roller corresponds to the waiting station. The layout of the lower waiting station facilitates manual replenishment of the feeding roller.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. This equipment adopts a dual-station layout with a deflection design for the waiting station. The dual feeding rollers can alternate feeding, while the waiting station is located below the equipment. When waiting for material, the feeding rollers can deflect outwards from the frame, allowing operators to change heavy film rolls in an open area. This reduces the labor load of handling heavy objects and makes the replenishment operation more convenient and efficient. At the same time, the replenishment area after deflection is completely isolated from the production operation area, avoiding the risk of contact with high-speed rotating parts during operation, ensuring the safety of personnel, and simultaneously meeting the pharmaceutical industry's dual requirements for ease of operation and safety.

[0030] 2. This equipment is equipped with two independent drive motors for each of the two feeding rollers, significantly enhancing the equipment's fault tolerance. If one drive motor malfunctions, the system can immediately switch to the other feeding roller to continue feeding material without stopping the entire production line, ensuring uninterrupted production. This design avoids production plan delays caused by single motor failures and reduces capacity losses due to downtime for maintenance, fully meeting the core requirements of the pharmaceutical industry for continuous production.

[0031] 3. The dual-station alternating feeding and synchronous replenishment design of this equipment enables continuous production of medical sleeves. The dual feeding rollers can switch between forward and reverse rotation by 180 degrees to complete alternating feeding. The deflection function of the waiting station allows the replenishment operation to be carried out synchronously during production, and the film roll can be changed without stopping the machine. After the material runs out, it can quickly switch to the standby station to continue film production, ensuring the continuous operation of the production line. This design greatly reduces the ineffective time spent on replenishment, significantly improves the overall production efficiency, and helps to stabilize and increase production capacity.

[0032] 4. The design of this equipment fully meets the requirements of the pharmaceutical industry for cleanliness and standardized operation in the production environment. The configuration of automated switching and deflection feeding reduces the frequency of contact between operators and the core production area, and reduces the risk of contamination from personnel entering and exiting. This layout ensures the cleanliness of the sleeve production process and meets the hygiene standards for the production of medical protective consumables. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0045] It should be noted that the detection module 3 in this equipment only provides film breakage detection and signal feedback functions (implemented through the structure of an existing through-beam photoelectric sensor, with the transmitter and receiver located on opposite sides of the film conveying path, monitoring the film occlusion status in real time, and immediately feeding back a signal to the station switching mechanism and sleeve forming module 4 when a breakage is detected, triggering switching and start / stop actions); the sleeve forming module 4 only provides film thermal bonding and fixed-length sealing and cutting functions (implemented through an existing continuous forming mechanism of thermal bonding component + sealing and cutting component, arranged sequentially along the conveying direction of the conveying system, first hot-pressing the film into a cylindrical structure, and then sealing and cutting to a preset length to form the finished cavity protective sleeve, and the operating status is adapted to the conveying speed of the conveying system); the external electric slide only provides the telescopic drive function of the support platform (implemented through the structure of an existing linear electric slide, receiving station switching and loading status). The status signal drives the support platform to move closer to or away from the feeding roller 21. During switching, it retracts to avoid collisions, and extends its support after the feeding roller 21 stabilizes. The support platform only provides the function of rotating support at the end of the feeding roller 21 (achieved through the existing support seat structure with bearings, forming a rotational fit with the end of the feeding roller 21, and cooperating with the roller shaft steering positioning seat 24 to achieve bidirectional support, preventing the feeding roller 21 from shaking during operation). The external flexible chain only provides the function of storing and protecting the circuit of the drive motor 231 (achieved through the structure of the existing engineering plastic flexible chain, adapting to the 180-degree forward and reverse trajectory of the axe strip 23, wrapping and storing the circuit, preventing the circuit from tangling, wearing or pulling during operation). The conveying system only provides the function of continuous film conveying (achieved through the existing guide roller group + conveying drive structure, connecting the feeding roller 21 and the sleeve forming processing module 4, achieving uniform and stable film conveying, and ensuring processing continuity).

[0046] The working principles (such as the photoelectric sensing and signal transmission principle of the detection module 3, the hot-press sealing and mechanical sealing principle of the sleeve forming processing module 4, the linear drive principle of the external electric slide, the rotational support principle of the support platform, the follow-up protection principle of the external flexible chain, and the friction conveying and tension adjustment principle of the conveying system, etc.) and specific structures (such as the sensing distance and response sensitivity of the detection module 3, the heat sealing temperature and sealing blade type of the sleeve forming processing module 4, the stroke and drive power of the external electric slide, the support diameter and bearing type of the support platform, the link specifications and bending radius of the external flexible chain, and the number of roller groups and guiding angle of the conveying system, etc.) of the above-mentioned components are all existing technologies. Given the universality of these structures, their specific principles will not be elaborated further.

[0047] Example 1, as Figure 1 , Figure 2 as well as Figure 9 As shown, a production equipment for endoscopic protective sleeves with material breakage detection includes a frame 1. A feeding module 2 is configured at the front end of the frame 1, and a sleeve forming and processing module 4 is configured at the rear end of the frame 1. A conveying system for conveying film is mounted on the frame 1. The feeding module 2 includes two feeding rollers 21 distributed vertically, each equipped with an independent drive assembly for independent rotation. The feeding module 2 is equipped with a station switching mechanism, which drives the two feeding rollers 21 to alternately switch to feeding stations adapted to the conveying system to convey film to the system. The feeding roller 21 at the feeding station is in the waiting position; each feeding roller 21 is equipped with a deflection component. The deflection component drives the feeding roller 21 to deflect horizontally away from the frame 1 only when the corresponding feeding roller 21 is in the waiting position, and performs a material replenishment operation on the feeding roller 21 in the waiting position; when the corresponding feeding roller 21 is in the feeding station, the deflection component is locked to maintain the adaptation state of the feeding roller 21 with the conveying system; a detection module 3 is set on the film conveying path of the conveying system. The detection module 3 is used to detect the material breakage state of the film conveying path.

[0048] like Figure 3 As shown, the workstation switching mechanism includes an arc-shaped guide positioning ring 22 fixedly connected to the frame 1. An axe bar 23 is slidably connected inside the arc-shaped guide positioning ring 22. A drive motor 25 for driving the axe bar 23 to rotate is installed outside the frame 1. Roller shaft steering positioning seats 24 are rotatably assembled at both ends of the axe bar 23. The feeding roller 21 is rotatably connected inside the roller shaft steering positioning seat 24.

[0049] like Figure 4 and Figure 6 As shown, drive motors 231 are mounted on both sides of the axe bar 23. The drive motors 231 and the corresponding feeding rollers 21 transmit power through a gear structure. The gear structure can switch with the work station to achieve selective engagement and disengagement of power.

[0050] like Figure 5 , Figure 6 as well as Figure 8 As shown, the gear structure includes two meshing driven bevel gears 243 mounted on the surface of the roller shaft steering positioning seat 24, and a driving bevel gear 242 fixedly connected to the output end of the drive motor 231; one of the driven bevel gears 243 is fixedly connected to the feeding roller 21, and the driving bevel gear 242 and the driven bevel gear 243 are normally meshed to transmit power. When the roller shaft steering positioning seat 24 rotates with the work position switching action, the driven bevel gear 243 on the corresponding side can separate from the driving bevel gear 242 with the rotation of the roller shaft steering positioning seat 24, thereby releasing the meshing state of the two.

[0051] like Figure 4 , Figure 5 , Figure 6 as well as Figure 8 As shown, both ends of the axe bar 23 are provided with pivoting grooves 232. The bottom of the roller shaft steering positioning seat 24 is fixedly connected with a pivoting column 241. The pivoting column 241 is rotatably adapted to the pivoting groove 232 to realize the rotatable connection between the axe bar 23 and the roller shaft steering positioning seat 24. The assembly positions of the pivoting column 241 and the pivoting groove 232 are respectively set in the outer area of ​​the gear structure. When the corresponding feeding roller 21 is in the waiting position, the pivoting column 241 is located on the side away from the sleeve forming processing module 4 to cooperate with the deflection component to drive the feeding roller 21 to deflect horizontally away from the frame 1.

[0052] like Figures 5 to 8 As shown, both the roller shaft steering positioning seat 24 and the axe bar 23 are equipped with locking components 244. The locking components 244 are used to selectively lock the rotational relationship between the roller shaft steering positioning seat 24 and the axe bar 23. Both the axe bar 23 and the roller shaft steering positioning seat 24 are provided with matching threaded holes. The locking component 244 is a bolt adapted to the threaded hole. By screwing the bolt into the corresponding threaded hole, the relative rotation between the roller shaft steering positioning seat 24 and the axe bar 23 can be locked.

[0053] It should be noted that the rotation logic of the drive motor 25 driving the axe bar 23 is as follows: first, the axe bar 23 is driven to rotate 180 degrees clockwise to complete one station switch, and then the axe bar 23 is driven to rotate 180 degrees counterclockwise, thus achieving the alternating switching of the two feeding rollers 21 in a cycle.

[0054] It should be added that the detection module 3 is used to monitor the continuous conveying status of the film in real time and provide feedback on the material interruption signal. The detection module 3 is connected to the station switching mechanism and the sleeve forming processing module 4 respectively. When the detection module 3 detects a material interruption, it triggers the station switching mechanism to switch the feeding roller 21, and simultaneously triggers the sleeve forming processing module 4 to pause operation. When the new feeding roller 21 is switched into place, the sleeve forming processing module 4 is triggered to resume operation. The sleeve forming processing module 4 is used to process the film conveyed by the conveying system into a cavity lens protective sleeve. The operating status of the sleeve forming processing module 4 is adapted to the conveying status of the conveying system. The detection module 3 is a through-beam photoelectric sensor, with its transmitting end and receiving end located on both sides of the film conveying path to monitor the continuous passage status of the film in real time. The sleeve forming processing module 4 includes a heat sealing component and a sealing and cutting component. The continuous forming mechanism and the sleeve forming processing module 4 are arranged sequentially along the conveying direction of the conveying system. They are used to heat-press the film into a cylindrical structure and then cut it into a finished cavity protective sleeve of a fixed length. The circuit of the drive motor 231 is arranged through an external flexible chain. The external flexible chain is adapted to the 180-degree forward and reverse trajectory of the axe 23 and is used to store the protective circuit and avoid the circuit from getting tangled or worn. The arc-shaped guide positioning ring 22 is a split structure. The arc-shaped guide positioning ring 22 is divided into at least two parts. The parts are detachably connected by fasteners so that the axe 23 can be assembled into the internal sliding path of the arc-shaped guide positioning ring 22. The two feeding rollers 21 are distributed vertically. The upper feeding roller 21 corresponds to the feeding station, and the lower feeding roller 21 corresponds to the waiting station. The layout of the lower waiting station makes it convenient for manual replenishment of the feeding roller 21.

[0055] like Figure 3 , Figure 7 as well as Figure 9 As shown, the roller steering positioning seat 24 is equipped with a limit strip on its surface. The limit strip and the axe bar 23 are in contact. The limit strip prevents the return angle deviation after the station switch, ensuring the matching accuracy between the feeding roller 21 and the conveying system. Figure 1 , Figure 2 as well as Figure 9 As shown, an externally driven electric slide support is provided at the end of the feeding roller 21 away from the roller shaft steering positioning seat 24. The external electric slide drives the support to move closer to / away from the feeding roller 21. During feeding or station switching, the support retracts and separates from the feeding roller 21. After the feeding roller 21 stabilizes, the support extends and forms a rotatable connection with the end of the feeding roller 21. Figure 2 As shown, the frame 1 has a boss on its exterior, and the drive motor 25 is fixedly mounted on the boss.

[0056] Specifically, in the initial stage of equipment operation, both feeding rollers 21, which are distributed vertically, are wound with film. The upper feeding roller 21 is in the feeding station adapted to the conveying system, and the lower feeding roller 21 is in the waiting station. The roller shaft turning positioning seats 24 corresponding to the two feeding rollers 21 are locked to the axe bar 23 by locking member 244.

[0057] After the equipment is started, a drive motor 231 on the axe bar 23 starts, and the meshing relationship between the active bevel gear 242 and the driven bevel gear 243 at its output end drives the upper feeding roller 21 to rotate independently, releasing the film wound on it at a uniform speed.

[0058] The film is conveyed to the sleeve forming module 4 at the rear of the frame 1 via the conveying system. The sleeve forming module 4 heat-presses the film into a cylindrical structure, and then seals and cuts it to a preset length to continuously form the cavity protective sleeve. During the process, the detection module 3, which is the transmitter and receiver of the through-beam photoelectric sensor, monitors the continuous passage status of the film in real time to ensure that there is no risk of material breakage during the conveying process.

[0059] When the detection module 3 detects a break in the film material, it immediately sends a break feedback signal to the station switching mechanism and the sleeve forming processing module 4. Upon receiving the signal, the sleeve forming processing module 4 quickly suspends the heat sealing and sealing operations to avoid equipment damage or product defects caused by processing without material.

[0060] At the same time, the drive motor 25 starts, driving the axe bar 23 to rotate 180 degrees clockwise on the sliding path inside the arc-shaped guide positioning ring 22, and driving the roller shafts at both ends of the axe bar 23 to rotate synchronously with the positioning seat 24, realizing the alternation of the work positions of the upper and lower feeding rollers 21. During this process, the external electric slide table drives the support table to retract and separate from the end of the feeding roller 21 to avoid interference with the rotation switching.

[0061] After the workstation switch is completed, the feeding roller 21, which was originally in the feeding workstation and has now been switched to the waiting workstation below, stops running. The operator first unscrews the locking part 244 corresponding to the feeding roller 21 from the threaded hole of the roller shaft turning positioning seat 24 and the axe 23, and then holds the roller shaft turning positioning seat 24 to rotate it.

[0062] Since the roller shaft steering positioning seat 24 forms a hinged engagement with the pivot engagement grooves 232 at both ends of the axe bar 23 through the pivot engagement column 241 at the bottom, during the rotation, the roller shaft steering positioning seat 24 drives the feeding roller 21 to deflect towards the outside of the frame 1. At this time, the driven bevel gear 243 mounted on the surface of the roller shaft steering positioning seat 24 disengages from the active bevel gear 242 at the output end of the drive motor 231 as the roller shaft steering positioning seat 24 rotates, thus avoiding interference in power transmission.

[0063] Because the waiting station is located below, and the deflected feeding roller 21 is far away from the working area of ​​the conveying system and the sleeve forming processing module 4, the operator can easily and safely remove the old film roll from the feeding roller 21 and replace it with a new film roll.

[0064] After the film is replaced, the operator reverses the rotation of the roller shaft to the positioning seat 24, causing it to drive the feeding roller 21 back to the initial waiting position. At this time, the pivoting engagement column 241 is reset in the pivoting engagement groove 232. Then, the locking piece 244 is screwed back into the matching threaded hole of the roller shaft to the positioning seat 24 and the axe bar 23 to complete the locking, ensuring that the feeding roller 21 is stably in the waiting position, waiting for the next position switch.

[0065] It should be added that the deflection function and dual-station layout of this equipment are of core necessity: the film rolls used are large in volume and heavy in weight. If the deflection function is not designed, even with a dual-station layout, when the operator is replenishing the material next to the equipment, the feeding area is close to the running conveyor system and sleeve forming processing module 4, which can easily lead to accidental contact with high-speed rotating parts and cause safety accidents.

[0066] The deflection function moves the feeding area from the inside of the equipment to the outside of the frame 1, completely isolating the feeding operation from the equipment operating area and fundamentally avoiding the risk of accidental contact.

[0067] Meanwhile, the waiting station for materials is located at the bottom, which is in line with ergonomic principles—operators do not need to lift the heavy film rolls upwards when replenishing materials, which is less strenuous than replenishing materials at a higher position, and greatly reduces labor intensity and operational difficulty.

[0068] In addition, production needs to be resumed quickly after material shortage. The dual-station + deflection design of this equipment can realize rapid material replenishment and film splicing, avoiding long-term downtime. More importantly, the dual stations are equipped with independent drive motors 231. When the drive motor 231 of one station fails, it can be immediately switched to the other normal station to continue production, completely solving the problem of production stoppage caused by a single drive motor failure.

[0069] Although the dual drive motor configuration slightly increases the equipment cost, the failure rate of drive motor 231 itself is low, and the design of the backup workstation can ensure production continuity. The resulting increase in production efficiency and avoidance of downtime losses far outweigh the additional cost, making it of significant practical value.

[0070] When the detection module 3 detects a material breakage again, the drive motor 25 drives the axe 23 to reverse 180 degrees, restoring the initial workstation layout. This cycle repeats, achieving continuous and stable operation of the equipment, which not only ensures production efficiency but also reduces the frequency of manual intervention.
