A three-dimensional warehouse with anti-falling mechanism for processing piston heads

Abstract

This invention discloses a three-dimensional warehouse with an anti-fall mechanism for piston head processing, comprising a storage rack with several sets of receiving slots for accommodating piston heads on one side. The storage rack is equipped with a storage and retrieval mechanism for storing and retrieving piston heads at target receiving slots. Each receiving slot is equipped with an anti-fall mechanism. The anti-fall mechanism includes a roller that is elastically rotatably mounted on the top wall of the receiving slot opening. The outer wall of the roller is equipped with a flexible sealing curtain for closing the slot opening. A counterweight is connected to the end of the flexible sealing curtain, and a transmission component is provided on the shaft of the roller. This invention achieves independent protection for each receiving slot by independently setting anti-fall mechanisms in each receiving slot and ensuring that the transmission component is driven by a drive component only when corresponding to the storage and retrieval mechanism to open the corresponding slot opening. The flexible sealing curtains of the remaining receiving slots remain closed, improving the anti-fall reliability of piston heads in non-receiving receiving slots during storage and retrieval operations.

Description

Technical Field

[0001] This invention relates to the field of piston head processing, and more specifically to an automated warehouse with a fall prevention mechanism for piston head processing. Background Technology

[0002] The piston head machining process involves multiple steps such as turning, grinding, polishing and surface treatment. Each step requires the use of an automated warehouse to temporarily store, rotate and buffer semi-finished piston heads in order to balance the production line cycle and improve the utilization of workshop space.

[0003] For example, the automated warehouse rack with a fall protection structure proposed in publication number CN121134214A can prevent goods from falling and achieve a fall protection effect by setting up scissor-type telescopic frames, but it still has the following defects in use: When the retrieval mechanism moves to the target layer, the entire scissor lift of that layer must be fully retracted and extended, exposing all goods placed on that layer. Goods in other locations that do not require retrieval lose lateral protection after the scissor lift retracts. At this point, the rack swaying caused by the retrieval operation is most severe, easily leading to goods in other locations falling due to lack of protection. The fall protection effect needs improvement. Furthermore, if the target location is at the limit of the scissor lift's retraction after the retrieval mechanism moves to the target layer, it is necessary to wait for the scissor lift to fully extend before exposing the target location, resulting in slow retrieval efficiency. Therefore, we propose an automated warehouse with a fall protection mechanism for piston head processing. Summary of the Invention

[0004] The purpose of this invention is to provide an automated warehouse with a fall prevention mechanism for piston head processing, which solves the technical problems mentioned in the background art.

[0005] The present invention achieves the above objectives through the following technical solutions: A three-dimensional warehouse with a fall protection mechanism for piston head processing includes a storage rack. A plurality of receiving slots for accommodating piston heads are provided on one side of the storage rack. The storage rack is provided with a storage and retrieval mechanism for storing and retrieving piston heads at the target receiving slot. Each receiving slot is provided with a fall protection mechanism. The anti-fall mechanism includes a roller that is rotatably mounted on the top wall of the accommodating slot. The outer wall of the roller is provided with a flexible sealing curtain for closing the slot. The end of the flexible sealing curtain is connected to a counterweight, which is vertically slidably mounted on the inner wall of the slot. The roller shaft is provided with a transmission component, which is used to drive the roller to rewind the flexible sealing curtain and open the slot when the storage and retrieval mechanism moves to the corresponding position.

[0006] A further improvement is that the storage and retrieval mechanism includes a placement seat for carrying the piston head, the placement seat is disposed on a position adjustment device, the position adjustment device is disposed on a storage shelf for driving the placement seat to the target receiving slot, and the placement seat is provided with a pick-and-place component and a drive component for driving the transmission component. The loading and unloading device includes slides symmetrically slidably mounted on both sides of the top of the placement seat, a mounting bracket mounted on the slides, a telescopic device 1 mounted on the placement seat for driving the slides to move, a telescopic device 2 mounted inside the mounting bracket, and a clamping plate mounted at the output end of the telescopic device 2 for contacting the outer wall of the piston head. The placement seat has a sliding groove 1 for the slides to slide, and the bottom wall of each receiving groove has a sliding groove 2 that cooperates with the sliding groove 1. The sliding groove 2 is used to communicate with the sliding groove 1 when the placement seat moves to the target receiving groove so that the slides can enter and exit the receiving groove.

[0007] A further improvement is that the transmission component includes a cavity 1 formed in the bottom wall thickness of the receiving groove, a positioning magnetic block is provided on the storage rack below the opening of the receiving groove, the positioning magnetic block is connected to the shaft of the roller component through a pull rope 2, and a guide component is provided on the side of the positioning magnetic block near the storage rack that can move through the storage rack and extend into the cavity 1. The driving component includes an opening on the side of the placement seat facing the storage shelf for the positioning magnetic block to pass through, an electromagnetic plate slidably disposed in the placement seat for energizing and attracting the positioning magnetic block, a winding device disposed in the placement seat, a pull rope connecting the winding device and the electromagnetic plate, and an elastic element connecting the electromagnetic plate and the inner wall of the placement seat to drive the electromagnetic plate to reset when the winding device unwinds the pull rope. When the winding device rewinds the pull rope, it drives the positioning magnetic block to move away from the storage shelf through the electromagnetic plate, thereby causing the pull rope to drive the roller to rewind the flexible closed curtain.

[0008] A further improvement is that the guide is a toothed plate, and the automated warehouse also includes an auxiliary mechanism. The auxiliary mechanism includes a rotatable roller located in the cavity. The outer wall of the roller is fitted with a gear that meshes with the toothed plate. A pull rope is also wound around the outer wall of the roller. A sleeve is provided on the top wall of the receiving groove. A connecting rod is movably inserted into the bottom of the sleeve. An elastic element is provided at the connection between the connecting rod and the sleeve. A pressure plate is provided at the bottom of the connecting rod for contacting the piston head. The end of the pull rope passes through the bottom wall of the receiving groove and the outer wall of the sleeve and is connected to the connecting rod. When the positioning magnetic block moves away from the storage shelf, the roller is driven by the toothed plate to rotate and wind up the pull rope, so that the connecting rod drives the pressure plate upward to a preset position.

[0009] A further improvement is that the automated warehouse also includes an auxiliary mechanism two, which includes a cleaning plate slidably disposed in the receiving slot and in contact with the bottom wall of the receiving slot, a limiting plate fixedly disposed on the bottom wall of the receiving slot and located on the side of the pressure plate away from the slot opening, an elastic element three connecting the bottom of the receiving slot and the cleaning plate, and a collection cavity opened on the bottom wall of the receiving slot and located between the limiting plate and the cavity one. The bottom wall of the receiving slot and the side of the limiting plate facing the slot opening has a feed port communicating with the collection cavity. A pull rope four is wound around the outer wall of the reel. The end of the pull rope four passes through the bottom wall of the receiving slot and the limiting plate and is connected to the cleaning plate. When the positioning magnetic block moves away from the storage shelf, the reel is driven by the toothed plate to rotate and rewind the pull rope four, so that the cleaning plate moves from the slot opening to contact the limiting plate.

[0010] A further improvement is that a detection sensor for detecting the piston head is embedded in the bottom wall of the receiving groove at a position corresponding to the pressure plate, an electromagnetic component is provided on the limiting plate, and a permanent magnet block that cooperates with the electromagnetic component is provided on the cleaning plate. When the detection sensor detects the piston head, the electromagnetic component is energized to attract the permanent magnet block.

[0011] A further improvement is that the collection chamber is connected to an external material collection device via a pipe fitting.

[0012] A further improvement is that the position adjustment device includes a Z-axis moving structure on the storage shelf, an X-axis moving mechanism on the Z-axis moving mechanism, and a Y-axis moving mechanism on the X-axis moving mechanism, with the placement seat located on the Y-axis moving mechanism.

[0013] The beneficial effects of this invention are as follows: 1) This invention achieves independent protection for a single receiving slot by independently setting up an anti-fall mechanism consisting of a roller, a flexible sealing curtain and a counterweight in each receiving slot, and by having the transmission component be driven by the drive component to open the corresponding slot only when it corresponds to the storage and retrieval mechanism. When the storage and retrieval mechanism moves to the target receiving slot, only the flexible sealing curtain of that receiving slot is rolled up and opened, while the flexible sealing curtains of the other receiving slots remain closed, preventing the piston heads in other receiving slots from losing protection and improving the anti-fall reliability of the piston heads in non-receiving receiving slots during storage and retrieval operations. 2) After the placement seat in the storage and retrieval mechanism moves to the target receiving slot, the positioning magnetic block and the electromagnetic plate are magnetically attracted, and then the winding equipment pull rope directly pulls the positioning magnetic block. Then, the pull rope drives the winding roller to wind up the flexible closed curtain to open the slot. This can realize rapid storage and retrieval at any position of the receiving slot, and automatically closes to prevent falling after storage and retrieval, ensuring the fall prevention effect while improving storage and retrieval efficiency. 3) The present invention uses auxiliary mechanism one to lift the pressure plate upwards to make room while the positioning magnetic block moves to open the flexible closed curtain. When the flexible closed curtain is reset, the pressure plate falls down to press the piston head, which further improves the protection against falling of the piston head in the receiving groove. At the same time, the cleaning plate of auxiliary mechanism two cleans the bottom wall of the receiving groove, which avoids foreign objects remaining in the receiving groove from damaging the piston head or causing it to tilt, further improving the anti-fall performance.

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1

[0018] Please see the appendix Figure 1-4 A three-dimensional warehouse with an anti-fall mechanism for piston head processing includes a storage rack 1. A plurality of receiving slots 101 for accommodating piston heads are provided on one side of the storage rack 1. The storage rack 1 is provided with a storage and retrieval mechanism 2 for storing and retrieving piston heads at the target receiving slot 101. Each receiving slot 101 is provided with an anti-fall mechanism 3. The fall arrestor 3 includes a roller 31 that is rotatably mounted on the top wall of the accommodating groove 101. In this embodiment, the roller 31 includes a housing fixed to the accommodating groove 101, a roller body rotatably mounted within the housing via a rotating shaft, an extension recess on the inner wall of the accommodating groove 101, an end of the rotating shaft extending into the extension recess and rotatably connected to the inner wall of the extension recess, and a torsion spring at the connection between the rotating shaft and the extension recess. The outer wall of the roller 31 is provided with a flexible sealing curtain 32 (which can be made of stainless steel woven mesh, high-strength industrial polyester fiber cloth, etc.) for sealing the groove. A counterweight 33 (such as a counterweight plate) is connected to the end of the flexible sealing curtain 32. The counterweight 33 is vertically slidably mounted on the inner wall of the groove. In this embodiment, the counterweight 33 has two... Each side is equipped with a slider, and the inner wall of the slot is provided with a vertical groove that cooperates with the slider. Through the sliding cooperation between the slider and the vertical groove, the smoothness of the counterweight 33 during vertical movement is ensured, and the counterweight 33 can be effectively prevented from shifting or jamming during lifting. When the roller 31 unwinds the flexible closed curtain 32, the counterweight 33 moves downward under its own weight, thereby relying on the weight of the counterweight 33 to stretch the flexible closed curtain 32 and close the slot, ensuring that the piston head in the receiving slot 101 will not fall accidentally due to shaking or other unexpected factors. The roller 31 shaft is provided with a transmission component, which is used to drive the roller 31 to rewind the flexible closed curtain 32 and open the slot when the storage mechanism 2 moves to the corresponding position. The working principle is as follows: When the storage and retrieval mechanism 2 moves to the target receiving slot 101, the storage and retrieval mechanism 2 and the transmission component work together. The transmission component drives the roller component 31 to rotate, thereby gradually rolling up the flexible closed curtain 32, so that the slot opening is fully opened for the storage and retrieval mechanism 2 to perform the piston head picking and placing operation; after the storage and retrieval mechanism 2 completes the operation and disengages from the transmission component, the torsion spring drives the roller component 31 to rotate in the opposite direction. The counterweight 33 slides down under its own weight and simultaneously pulls up the flexible closed curtain 32, so that the slot opening is restored to the closed state, thereby forming a continuous and reliable anti-fall protection for the piston head in the receiving slot 101 during non-storage and retrieval periods.

[0019] Please see the appendix Figure 1-4 As a preferred embodiment, the storage and retrieval mechanism 2 includes a placement seat 22 for carrying the piston head. The placement seat 22 is disposed on a position adjustment device 21, which is disposed on a storage rack 1 for driving the placement seat 22 to move to the target receiving slot 101. The placement seat 22 is provided with a pick-and-place member 23 and a drive member for driving the transmission member. The loading and unloading component 23 includes slide blocks 231 symmetrically slidably disposed on both sides of the top of the placement seat 22, a mounting bracket 232 disposed on the slide blocks 231, a telescopic device 234 (such as a hydraulic cylinder) disposed on the placement seat 22 for driving the slide blocks 231 to move, a telescopic device 234 (such as a hydraulic cylinder) disposed inside the mounting bracket 232, and a clamping plate 233 disposed at the output end of the telescopic device 2 for contacting the outer wall of the piston head. Preferably, a rubber pad layer can be adhered to the inner side of the clamping plate 233 to increase the friction with the piston head and prevent scratching. The piston head surface is damaged. The placement seat 22 is provided with a sliding groove 1 for sliding seat 231. The bottom wall of each receiving groove 101 is provided with a sliding groove 2 that cooperates with the sliding groove 1. The sliding groove 2 is used to connect with the sliding groove 1 when the placement seat 22 moves to the target receiving groove 101 so that the sliding seat 231 can enter and exit the receiving groove 101. The docking of the sliding groove 1 and the sliding groove 2 not only ensures the extension of the stroke of the sliding seat 231, but also plays a guiding role in the positioning and alignment between the placement seat 22 and the receiving groove 101, effectively improving the centering accuracy of the pick-and-place component 23 being pushed into the piston head. The working principle is as follows: When the piston head needs to be placed into the receiving slot 101, an external device (such as a robotic arm) can place the piston head on the placement seat 22 and between the two clamping plates 233. Then, the telescopic device drives the clamping plates 233 to move towards each other to clamp and contact the piston head, thereby reliably constraining the piston head on the placement seat 22 during storage and transportation, effectively preventing the piston head from accidentally falling due to shaking or other factors during storage and transportation. Subsequently, the position adjustment device 21 moves the placement seat 22 to the target receiving slot 101 and aligns it with the receiving slot 101. The drive component drives the transmission component to open the slot. After opening, the telescopic device 234 drives the slide 231 to slide along the slide groove 1 and slide groove 2 into the receiving groove 101, which pushes the piston head smoothly into the receiving groove 101. When the piston head reaches the preset placement position in the receiving groove 101, the telescopic device 2 drives the clamping plate 233 to release the piston head, and the telescopic device 234 drives the slide 231 to reset and exit the receiving groove 101. The driving component disengages from the transmission component, causing the anti-fall mechanism 3 to re-close the groove opening, thereby completing the safe and automated storage and retrieval work. This method realizes multiple protections for the piston head in the entire storage and retrieval process, which greatly reduces the risk of the piston head falling.

[0020] As a preferred embodiment, the transmission component includes a cavity 36 formed within the bottom wall thickness of the receiving groove 101 (i.e., the wall thickness of the storage rack 1). A positioning magnetic block 35 (preferably a ferromagnetic block) is provided on the storage rack 1 below the opening of the receiving groove 101. The positioning magnetic block 35 is connected to the shaft of the roller component 31 via a pull rope 34 (preferably a high-strength steel wire rope or aramid fiber rope). The pull rope 34 passes through the bottom wall of the receiving groove 101 and extends into the cavity 36, and then passes through the side wall of the cavity 36 to connect with the positioning magnetic block 35. It should be noted that a guide structure, such as a guide wheel or a ceramic guide ring, can be provided on the movement path of the pull rope 34. This will not be described in detail here. A guide member is provided on the side of the positioning magnetic block 35 near the storage rack 1, which moves through the storage rack 1 and extends into the cavity 36. This guide member ensures that the positioning magnetic block 35 moves back and forth only in a direction perpendicular to the side wall of the storage rack 1 without deflection. The driving component includes a through-hole opened on the side of the placement base 22 facing the storage shelf 1, through which the positioning magnetic block 35 passes (when the placement base 22 is moved by the position adjustment device 21 to align with the target receiving slot 101, the positioning magnetic block 35 of the target receiving slot 101 passes through the through-hole and extends into the placement base 22 to achieve docking), an electromagnetic plate 24 slidably disposed in the placement base 22 for electrically adsorbing the positioning magnetic block 35 (its side facing the positioning magnetic block 35 is a magnetic adsorption surface, initially in contact with the positioning magnetic block 35 passing through the through-hole), and a placement plate 24 (the side facing the positioning magnetic block 35 is a magnetic adsorption surface, initially in contact with the positioning magnetic block 35 passing through the through-hole). The winding device 25 (including a micro servo motor and a micro reducer) inside the seat 22, the pull rope 26 (of the same material as the pull rope 34) connecting the winding device 25 and the electromagnetic plate 24, and the elastic element (such as a spring) connecting the electromagnetic plate 24 and the inner wall of the seat 22 to drive the electromagnetic plate 24 to reset when the winding device 25 unwinds the pull rope 26, the winding device 25 drives the positioning magnet 35 to move away from the storage shelf 1 through the electromagnetic plate 24 when winding the pull rope 26, thereby causing the pull rope 34 to drive the roller 31 to wind up the flexible closed curtain 32; The working principle is as follows: When the target receiving slot 101 needs to be opened, the winding device 25 starts and winds up the pull rope 26. The pull rope 26 pulls the electromagnetic plate 24 to move towards the winding device 25. Since the electromagnetic plate 24 is magnetically connected to the positioning magnetic block 35 when it is energized, the electromagnetic plate 24 synchronously drives the positioning magnetic block 35 to move away from the storage rack 1. During the movement of the positioning magnetic block 35, the pull rope 24 pulls the roller 31 to rotate, thereby forcing the roller 31 to gradually retract the flexible closed curtain 32. The slot is opened to allow the retrieval and placement device 23 to perform the piston head storage and retrieval operation. After storage and retrieval are completed, the winding device 25 unwinds the pull rope 26 in the opposite direction. The elastic element 1 drives the electromagnetic plate 24 to reset. At the same time, the positioning magnetic block 35 returns to its position with the pull rope 24 under the combined action of the torsion spring and the counterweight 33. The flexible closed curtain 32 re-closes the slot.

[0021] Preferably, the position adjustment device 21 in this embodiment includes a Z-axis moving structure on the storage rack 1, an X-axis moving mechanism on the Z-axis moving mechanism, and a Y-axis moving mechanism on the X-axis moving mechanism, with the placement seat 22 on the Y-axis moving mechanism. Optionally, in this embodiment, the Z-axis moving structure preferably adopts a linear guide pair and a lead screw and nut drive assembly arranged vertically along the storage rack 1. The lead screw is driven by a servo motor and a reducer to achieve precise positioning and self-locking of the placement seat 22 in the vertical direction. The X-axis moving mechanism preferably adopts a linear module or a gear and rack drive module that spans the width direction of the storage rack 1 to achieve rapid horizontal displacement. The Y-axis moving mechanism preferably adopts a slide module driven by a cylinder or an electric push rod. Its fixed end is installed on the sliding part of the X-axis moving mechanism, and the placement seat 22 is fixed on the output end of the Y-axis moving mechanism. Through this position adjustment device 21, the placement seat 22 can be moved to any position in the three-dimensional space in front of the storage rack 1.

[0022] Example 2

[0023] Please see the appendix Figure 2-4 Based on Embodiment 1, the guide in this embodiment is a toothed plate 41, the length of which is parallel to the moving direction of the positioning magnetic block 35. The automated warehouse also includes an auxiliary mechanism 4, which includes a rotatable roller 42 housed within a cavity 36. The axis of the roller 42 is parallel to the length of the cavity 36, and both ends are rotatably supported on the inner wall of the cavity 36 via bearings. A gear that meshes with a toothed plate 41 is fitted on the outer wall of the roller 42. A pull rope 46 is also wound around the outer wall of the roller 42. A sleeve 43 (vertically arranged) is provided on the top wall of the receiving groove 101. A connecting rod 44 is movably inserted into the bottom of the sleeve 43. The vertical section of the connecting rod 44 is T-shaped to prevent the connecting rod 44 from coming out of the sleeve 43. An elastic element (such as a spring) is provided at the connection between the connecting rod 44 and the sleeve 43. A spring, one end of which is connected to the bottom of the connecting rod 44 and the other end of which is connected to the bottom of the sleeve 43, is used to provide a continuous downward elastic thrust for the connecting rod 44. The bottom of the connecting rod 44 is provided with a pressure plate 45 for contacting the piston head (the pressure plate 45 is preferably made of polyurethane material and its bottom surface is provided with anti-slip texture to increase the contact friction with the end face of the piston head). The end of the pull rope 3 46 passes through the bottom wall of the receiving groove 101 and the outer wall of the sleeve 43 and is connected to the connecting rod 44. When the positioning magnetic block 35 moves away from the storage rack 1, the reel 42 is driven by the toothed plate 41 to rotate and reel in the pull rope 3 46, so that the connecting rod 44 drives the pressure plate 45 upward to the preset position. Working principle: When the positioning magnetic block 35 is attracted by the electromagnetic plate 24 and moves away from the storage shelf 1, the toothed plate 41 moves outward synchronously. The toothed plate 41 drives the roller 42 to rotate through meshing with the gear. During the rotation of the roller 42, the pull rope 3 46 is wound up. The end of the pull rope 3 46 pulls the connecting rod 44 to slide upward along the sleeve 43, thereby driving the pressure plate 45 to move upward to the preset position to make room for the piston head to be pushed in. When the positioning magnetic block 35 is reset, the toothed plate 41 moves in the opposite direction to drive the roller 42 to rotate in the opposite direction to release the pull rope 3 46. The connecting rod 44 slides downward to reset under the elastic force of the elastic element 2. The pressure plate 45 is pressed back onto the piston head end face that has been placed in place. Thus, on the basis of the flexible closed curtain 32 being closed, the pressure plate 45 applies an axial pre-tightening force to the piston head end face from the piston head end face, effectively preventing the piston head from moving and falling in the receiving groove 101 due to shaking or other factors.

[0024] Example 3

[0025] Please see the appendix Figure 2-4 Based on Embodiment 2, the automated warehouse in this embodiment further includes an auxiliary mechanism 2 5. The auxiliary mechanism 2 5 includes a cleaning plate 53 (its length is adapted to the length of the receiving groove 101, and its bottom surface is preferably inlaid with felt or polyurethane scraper to enhance the cleaning effect; guide protrusions can be provided on both sides of the cleaning plate 53 to cooperate with the guide grooves on the side wall of the receiving groove 101 to ensure that it always stays in contact with the bottom wall and does not deviate when it moves back and forth), a limiting plate 52 (used to limit the limit stroke of the cleaning plate 53 and provide a mounting base) fixedly disposed on the bottom wall of the receiving groove 101 and located on the side of the pressure plate 45 away from the groove opening, and connecting the bottom of the receiving groove 101 and the cleaning plate 53. The plate 53 has an elastic element three (such as a spring), and a collection cavity 54 is opened on the bottom wall of the receiving groove 101 and located between the limiting plate 52 and the cavity 36. The bottom wall of the receiving groove 101 and the side of the limiting plate 52 facing the groove opening is provided with a feed port 56 communicating with the collection cavity 54. The feed port 56 is preferably a strip-shaped long groove extending along the length direction of the receiving groove 101. The outer wall of the reel 42 is wound with a pull rope four 51. The end of the pull rope four 51 passes through the bottom wall of the receiving groove 101 and the limiting plate 52 and is connected to the cleaning plate 53. When the positioning magnetic block 35 moves away from the storage rack 1, the reel 42 is driven by the toothed plate 41 to rotate and wind up the pull rope four 51 so that the cleaning plate 53 moves from the groove opening to contact the limiting plate 52. The working principle is as follows: When the positioning magnetic block 35 is attracted by the electromagnetic plate 24 and moves away from the storage rack 1, the toothed plate 41 drives the roller 42 to rotate. The roller 42 simultaneously winds up the pull rope 46 and pull rope 51. The pull rope 51 pulls the cleaning plate 53 from the slot towards the limiting plate 52. During the sliding process, the cleaning plate 53 pushes the foreign objects (such as metal scraps, dust, etc.) on the bottom wall of the receiving slot 101 it passes through towards the feed inlet 56. The foreign objects fall into the collection chamber 54 through the feed inlet 56 for centralized collection. When the cleaning plate 53 moves to contact the limiting plate 52, When the cleaning cycle is completed at the limit position, the pressure plate 45 is also in the preset position and the slot is fully open. When the positioning magnetic block 35 is reset, the roller 42 rotates in the opposite direction to release the pull rope 4 51. The cleaning plate 53 slides back to the vicinity of the slot under the elastic force of the elastic element 3, preparing for the next cleaning. This method realizes automatic cleaning of the bottom wall of the receiving slot 101, effectively avoiding the piston head being tilted or scratched due to foreign objects on the bottom wall when it is put into the receiving slot 101, ensuring the long-term reliability of the anti-fall mechanism 3 and the positional accuracy of the piston head.

[0026] Please see the appendix Figure 2 and attached Figure 4 Preferably, in this embodiment, a detection sensor 55 for detecting the piston head is embedded in the bottom wall of the receiving groove 101 at a position corresponding to the pressure plate 45. This detection sensor 55 is preferably an inductive proximity switch or a photoelectric reflective sensor, with its detection surface flush with the bottom wall of the receiving groove 101 to avoid interfering with the sliding of the cleaning plate 53. An electromagnetic component is provided on the limiting plate 52, and a permanent magnet block cooperating with the electromagnetic component is provided on the cleaning plate 53. This permanent magnet block is preferably a neodymium iron boron magnet and is embedded on the side of the cleaning plate 53 facing the limiting plate 52. When the detection sensor 55 detects the piston head, the control electromagnetic component is energized to attract the permanent magnet block. In this embodiment, both the detection sensor 55 and the electromagnetic component are electrically connected to an external controller. The working principle is as follows: When the detection sensor 55 detects that a piston head is placed in the receiving groove 101, it sends a signal to the controller. The controller controls the electromagnetic component to be energized to attract the cleaning plate 53, firmly holding the cleaning plate 53 in the limit position of the limiting plate 52, preventing it from moving towards the groove opening. Thus, when the positioning magnetic block 35 is reset and the reel 42 releases the pull rope 4 51, even if the elastic component 3 applies a pushing force towards the groove opening to the cleaning plate 53, the cleaning plate 53 will not slide towards the groove opening, thus preventing the piston head already placed in the receiving groove 101 from being pushed outward, ensuring the stability of the piston head's position in the receiving groove 101. When the piston head is removed, the signal from the detection sensor 55 disappears, the controller controls the electromagnetic component to be de-energized, the cleaning plate 53 is unlocked, and the cleaning plate 53 can then move or reset under the action of the pull rope 4 51 and the elastic component 3.

[0027] Preferably, in this embodiment, the collection chamber 54 is connected to an external collection device via a pipe fitting 102. The pipe fitting 102 is preferably a wear-resistant corrugated hose. One end of the pipe fitting 102 is sealed to the collection chamber 54 via a quick connector, and the other end is connected to the external collection device. The external collection device is, for example, an industrial vacuum negative pressure collection box, which is equipped with a filter bag and a negative pressure fan to provide continuous suction.
