Description

Technical Field

[0001] This utility model relates to a padlock polishing device, and more particularly to an automatic padlock polishing device. Background Technology

[0002] During padlock manufacturing, polishing is required on all surfaces of the padlock body. With technological advancements, existing padlock surface polishing equipment primarily employs two methods: manual movement of the padlock or mechanical clamping. While manual movement allows polishing with the key in hand, the entire process requires manual movement of the padlock, and polishing the sides involves manually holding the lock, which can lead to uneven polishing and poor overall efficiency and polishing results. While mechanical clamping is more efficient than manual operation, it still provides a more refined and effective polishing process. While this method can reduce labor intensity to some extent, the clamping space of this mechanical clamping method is limited. When the padlock has a key, the shape and position of the key will interfere with the clamping stability of the clamping device. Furthermore, existing padlock polishing equipment sets the polishing head and clamping device according to padlocks without keys, influencing the position, movement path, and timing of each action. Once a key is on the padlock, not only will the lock shift during polishing, but it may also affect the normal operation of the polishing head. Consequently, manual removal of the key from the padlock is required before polishing, and manual replacement of the key after polishing, resulting in low overall work efficiency. Therefore, existing padlock polishing equipment suffers from low work efficiency when polishing locks with keys. Utility Model Content

[0003] The purpose of this invention is to provide an automatic padlock polishing device. This invention has the advantage of high working efficiency.

[0004] The technical solution of this utility model is as follows: An automatic padlock polishing device includes a frame, a controller mounted on the frame, a material transfer device, and a material feeding channel. A first pushing device and a lock flipping device are respectively arranged on both sides of the material transfer device. A guide seat fixedly mounted on the frame is provided between the lock flipping device and the material transfer device. The guide seat has a through hole for the vertical passage of the lock key. A feeding seat for placing the lock is provided between the guide seat and the lock flipping device. A stroke-adjustable cylinder mounted vertically on the frame is connected to the bottom surface of the feeding seat. A first polishing device is arranged directly above the feeding seat. A middle channel fixedly mounted on the frame is provided on one side of the feeding seat, and a second pushing device for pushing the lock from the feeding seat onto the middle channel is provided on the other side. A gap for the lock key to pass through is provided between the middle channel and the material transfer device. The material transfer device, the first pushing device, and the lock flipping device are all present. The device, the second pushing device, the stroke-adjustable cylinder, and the first polishing device are all electrically connected to the controller. When the first pushing device is working, it pushes the lock out of the transfer device, through the guide seat, and finally moves it to the discharge seat. The guide seat not only supports and guides the movement of the lock as it is pushed from the transfer device to the discharge seat by the first pushing device, ensuring the stability of the operation, but also provides a channel for the key to fall through the guide seat, preventing the lock from becoming uneven or shifting due to the key being blocked. This ensures the overall polishing effect and improves the polishing efficiency. In addition, the space between the middle channel and the transfer device for the key to pass through allows the second pushing device to push the lock stably and smoothly from the discharge seat to the middle channel without the lock getting stuck, ensuring the stability of the operation.

[0005] In the aforementioned automatic padlock polishing equipment, the first polishing device includes a first polishing frame, on which a first polishing drive wheel and a first polishing driven wheel are mounted.

A drive shaft is mounted on the first polishing drive wheel. A first polishing motor is positioned on the drive shaft away from the end of the first polishing drive wheel, and a drive belt is installed between the first polishing motor and the drive shaft. An adjusting seat is rotatably mounted on the first polishing frame, and the top surface of the adjusting seat is connected to the first alignment wheel via a hinge. The rotation axis of the hinge is perpendicular to the axis of the first alignment wheel. A first shock absorber is installed between the adjusting seat and the first polishing frame. The first shock absorber can counteract the vibration generated by the abrasive belt during the polishing process, preventing the vibration from being transmitted to the feeding seat, causing fluctuations in the lock body position, and thus affecting the contact stability between the lock body and the first polishing abrasive belt, thereby ensuring the polishing effect.

[0006] In the aforementioned automatic padlock polishing device, the first straightening wheel has an upwardly convex arc surface, and a retaining ring is provided on the first straightening wheel to prevent the first polishing abrasive belt from detaching from it. A connecting seat is provided on the first straightening wheel at the position corresponding to its connection with the hinge, and a first U-shaped groove is provided on the connecting seat at the position corresponding to its connection with the first straightening wheel. An adjusting bolt is rotatably installed on the adjusting seat, and the end of the adjusting bolt is connected to the bottom end of the side of the connecting seat.

By installing the first straightening wheel on the adjusting seat through a hinge connection, and considering that the entire surface of the top of the first straightening wheel is an upwardly convex arc surface, the first polishing abrasive belt can be kept taut during the polishing process, thereby ensuring the polishing effect of the first polishing abrasive belt on the lock. The first dust suction hood can centrally process the debris generated and carried by the first polishing abrasive belt during the polishing process, avoiding the phenomenon of debris flying everywhere, facilitating cleaning, and ensuring a comfortable working environment.

[0007] In the aforementioned automatic padlock polishing equipment, the adjustable stroke cylinder is equipped with a first positioning magnetic induction switch for detecting whether the adjustable stroke cylinder pushes the lock upward and makes contact with the first polishing device, and a first origin magnetic induction switch for detecting whether the adjustable stroke cylinder drives the feeding seat downward and moves it to a position flush with the guide seat. Both the first positioning magnetic induction switch and the first origin magnetic induction switch are electrically connected to the controller. The first positioning magnetic induction switch and the second origin magnetic induction switch can be used to detect whether the adjustable stroke cylinder has pushed out and returned to its original position, thereby enabling the controller to more accurately control the start and stop of the lock flipping device, the second feeding device, and other devices, avoiding the occurrence of action conflicts between the lock flipping device or the second feeding device, and ensuring the stability of the operation.

The first proximity sensor can detect whether the lock is being pushed into the feeding seat, so as to ensure the accuracy of the first pusher and the stroke adjustable cylinder, and further ensure the stability of the operation. The stop on one side of the feeding seat is set in the rotation direction of the first polishing device, so that the stop can block the lock on one side and prevent the lock from falling off during the polishing process. The top surface of the stop is set directly below the second pusher, so that the stop will not affect the normal pushing operation of the second pusher.

[0009] In the aforementioned automatic padlock polishing equipment, a pusher support is provided between the feeding channel and the intermediate channel, and a third pusher seat is slidably mounted on the top surface of the pusher support.

A positioning element is provided at the bottom of the side of the third pusher seat. A front positioning block and a rear positioning block, located on the moving path of the positioning element, are provided on the top surface of the pusher support seat. The positioning cylinder works synchronously with the second pusher device. A U-shaped connecting seat is provided at the end of the piston rod of the third pusher cylinder, and the U-shaped connecting seat is slidably mounted on the top surface of the clamping support seat. A first rotating shaft is rotatably mounted on the U-shaped connecting seat. A clamping base is provided on the top surface of the third pusher seat.

[0011] In the aforementioned automatic padlock polishing equipment, the second polishing device includes a second polishing frame, on which a second polishing drive wheel is mounted. Two second polishing driven wheels, symmetrically arranged vertically, are mounted on the upper side of the second polishing drive wheel near the third pusher seat. A second polishing motor is connected to the second polishing drive wheel. A second alignment wheel is mounted above the second polishing drive wheel. A second shock absorber, with one end mounted on the second polishing frame, is connected to the second alignment wheel. A second polishing abrasive belt is positioned between the second alignment wheel, the second polishing drive wheel, and the second polishing driven wheels. An auxiliary push cylinder is positioned between the two second polishing driven wheels, and a push shaft is mounted on the auxiliary push cylinder. An auxiliary clamping seat is connected to the end of the push shaft, and a spring is sleeved on the push shaft. One end of the spring is fixedly mounted on the auxiliary clamping seat, and the other end is fixedly mounted on the end face of the auxiliary push cylinder. A second dust suction hood is positioned between the bottom surfaces of the two second polishing abrasive belts. The second polishing motor and the auxiliary push cylinder are both electrically connected to a controller.

[0012] In the aforementioned automatic padlock polishing equipment, the first pushing device includes a first pushing cylinder, on which a first pushing component is connected; the end face of the first pushing component is provided with a groove for the lock key to pass through, and both sides of the first pushing component are provided with pushing guides; the first pushing cylinder is provided with a third positioning magnetic induction switch for detecting whether the first pushing cylinder has pushed out to the correct position and a third origin magnetic induction switch for detecting whether the first pushing cylinder has returned to the correct position; the lock flipping device includes a flipping base slidably mounted on the frame, and a flipping component is connected to the side of the flipping base away from the feeding seat. The platform is equipped with a translation cylinder; a tilting platform lifting cylinder is installed on the top surface of the tilting base, and a tilting translation seat is connected to the tilting platform lifting cylinder; a rotary motor is installed on the top surface of the tilting translation seat, and a rotary seat is installed on the rotary motor; a tilting platform clamping cylinder is installed on the rotary seat, and two clamping parts for clamping the locking beam are provided on the tilting platform clamping cylinder; a limit component is provided on the top surface of the frame, and the limit component is located on the path of the tilting base moving towards the feeding seat; four lifting guide rails are provided on the outer circumference of the tilting platform lifting cylinder, and the tilting translation seat is slidably connected to each lifting guide rail.

[0013] In the aforementioned automatic padlock polishing equipment, the material transfer device includes a feeding drive shaft and a feeding driven shaft, with a feeding motor connected to the feeding drive shaft; a feeding conveyor belt is installed between the feeding drive shaft and the feeding driven shaft, with feeding baffles on both sides of the feeding conveyor belt, one end of which is aligned with the end of the second pushing device; a feeding limit stop is provided on the feeding conveyor belt at a position corresponding to one side of the middle channel, and a second proximity sensor for detecting whether a lock is in contact with the feeding limit stop is installed on the feeding limit stop, the second proximity sensor being electrically connected to a controller; a support plate is vertically installed on the frame at a position corresponding to one side of the material feeding seat, and a slide rail is provided on the side of the support plate facing the material feeding seat, with a sliding seat slidably installed on the slide rail; one side of the material feeding seat is fixedly installed on the sliding seat; an elastic clip is installed on the top surface of the middle channel near the end of the third pushing seat, and a rubber pad is attached to the bottom surface of the elastic clip; a protective cover is installed on the frame.

[0014] Compared with existing technologies, this utility model improves upon existing padlock polishing equipment. By installing a guide seat between the material transfer device and the material dispensing seat, the guide seat supports and guides the movement of the lock as it is pushed from the material transfer device to the material dispensing seat by the first material pushing device, preventing the lock from falling and ensuring operational stability. Furthermore, the through-hole on the guide seat provides a passage for the key after pushing and flipping the lock, preventing unevenness or misalignment of the lock due to the key being blocked. This ensures an overall polishing effect and allows the device to polish the lock while carrying the key. Compared to previous lock polishing devices that required removing the key before polishing and then reinserting it afterward, this utility model... This system enables direct polishing of locks with keys attached. Combined with a controller that manages the actions and coordination of various electrical components, it achieves automated polishing. This significantly increases the efficiency, from 4,000-5,000 locks polished by three workers per day to approximately 20,000 locks polished by one worker per day. Furthermore, the space between the central channel and the material transfer device allows the key to pass smoothly and stably, preventing locks from getting stuck. This ensures stability and avoids uneven placement of locks due to the key during subsequent flipping, preventing polishing position misalignment during the second polishing process after flipping and guaranteeing optimal polishing results.

[0015] Furthermore, this invention also connects a first magnetic induction switch to the adjustable stroke cylinder. The first position magnetic induction switch and the second origin magnetic induction switch can respectively detect whether the adjustable stroke cylinder has reached its extended and returned positions. This allows the controller to more accurately control the start and stop of the lock flipping device, the second pushing device, and other devices, avoiding any conflict between the lock flipping device or the second pushing device and ensuring operational stability. Additionally, a first proximity sensor is installed on the feeding seat to detect whether a lock has been pushed into the feeding seat, ensuring the proper functioning of the first pushing device and the adjustable stroke cylinder. Precision further ensures operational stability. An adjusting seat is installed on the polishing frame, and a first shock absorber is placed between the adjusting seat and the first polishing frame. This first shock absorber effectively counteracts the vibrations generated by the abrasive belt during polishing, preventing vibrations from being transmitted to the feeding seat and causing fluctuations in the lock body's position. This, in turn, affects the contact stability between the lock body and the first polishing abrasive belt, ensuring the polishing effect. The first alignment wheel is mounted on the adjusting seat via a hinge, and its top surface is an upward-convex arc, ensuring the first polishing abrasive belt remains taut throughout the polishing process, thus guaranteeing the proper contact between the first polishing abrasive belt and the lock. The polishing effect is achieved by providing a first dust suction hood on one side of the first polishing belt. This hood collects and collects the debris generated and carried during the polishing process, preventing debris from scattering and facilitating cleaning while ensuring a comfortable working environment. A limiting component on one side of the tilting base restricts the distance the tilting base moves towards the feeding seat, preventing over-movement and ensuring operational stability. A clamping top seat is rotatably mounted on the mounting component, and the clamping moving seat is rotatably mounted together with the clamping top seat. This allows the clamping moving seat to move smoothly when the third pushing cylinder pushes the clamping moving seat. When the moving seat moves, it simultaneously pushes the clamping top seat to rotate, causing the clamping top seat located above the clamping base to automatically flip downwards and cooperate with the clamping base to fix the lock. This allows the clamping and translation of the lock to be achieved using only one third pusher cylinder, making the overall structure simpler. A storage platform rotatably mounted on the frame is set on one side of the third pusher seat, and a positioning cylinder is set on one side of the storage platform. The positioning cylinder and the storage platform cooperate to position the lock brought in by the pusher, ensuring that the position of the lock pushed onto the clamping base is fixed and only one each time, thus ensuring the stability of the operation.The rotating installation of the storage platform, in conjunction with the support block on the third pusher seat, allows the support block to move from the suspended end of the storage platform to the end mounted on the frame as the third pusher is pushed towards the second polishing device. This reduces the supporting force on the suspended end of the storage platform, enabling the platform to automatically flip downwards and guide the locks onto the platform into the unloading channel for automatic unloading, thus simplifying operation. Furthermore, a second shock absorber is installed between the second alignment wheel and the second polishing frame to counteract the vibrations generated by the second polishing belt during polishing, preventing the vibrations from being transmitted to the third pusher seat and causing lock body position fluctuations, which would affect the contact between the lock body and the second polishing belt. Stability is further ensured, guaranteeing the polishing effect. An auxiliary pushing cylinder and an auxiliary clamping seat are installed between the second and first polishing driving wheels, improving the fit between the second polishing belt and the side of the lock body, thus ensuring a good polishing effect. The spring between the auxiliary pushing cylinder and the auxiliary clamping seat reduces the pushing force of the auxiliary pushing cylinder, preventing the two auxiliary clamping seats from clamping the lock too tightly, which could prevent the second polishing belt from polishing the lock, ensuring operational stability. A second dust suction hood is installed directly below the second polishing belt. This hood not only collects and treats debris generated during polishing but also effectively prevents metal dust from flying and being inhaled by the operator. This design further ensures work comfort and facilitates subsequent cleaning. A stop is installed on the top surface of the feeding seat near the end of the second pushing device, blocking the lock from one side and preventing it from slipping and falling off due to friction during polishing with the first polishing belt, thus ensuring work stability. A second proximity sensor is installed on the feeding conveyor belt to determine whether the lock has been moved between the first pushing device and the guide seat, allowing the controller to precisely control the start and stop of the first pushing device, ensuring work stability. The feeding baffles on both sides of the feeding conveyor belt limit the movement of the lock body. This design avoids positional shifts in the lock body during material feeding, ensuring operational stability. A slide rail and sliding seat on one side of the feeding platform not only support the platform but also guide its movement, guaranteeing structural and operational stability. Elastic catches at the ends of the central channel provide resistance on the top surface of the locks, allowing them to be pushed steadily one by one to the next station, further ensuring operational stability. A protective cover installed on the entire frame, housing all devices within it, effectively prevents operators from coming into contact with the first and second polishing devices, ensuring safety during use.Furthermore, the protective cover can, to a certain extent, prevent the debris generated during polishing from flying everywhere, further ensuring user comfort. By installing second origin magnetic induction switches, second position magnetic induction switches, third origin magnetic induction switches, third position magnetic induction switches, fourth origin magnetic induction switches, and fourth position magnetic induction switches on the first, second, and third pusher cylinders respectively, the movement of the first, second, and third pusher cylinders can be detected to ensure they are in position. This facilitates the controller's control of each station of the entire device, making it convenient to use. By connecting the first polishing motor and the first polishing drive wheel with two single shafts, two bearing seats, and a transmission belt, the installation position of the first polishing motor can be more flexible and installation is more convenient. Therefore, this utility model not only improves work efficiency but also has the advantages of high work stability, good polishing effect, easy cleaning, high user comfort, and high safety.

[0032] Working principle: Before polishing, the entire device is placed on a horizontal surface and connected to an external safe mains power supply, which powers and starts the controller 2, the first proximity sensor 9, the second proximity sensor 52, the first polishing motor 13, and the second polishing motor 35. (The controller 2 used in this application can specifically be a model such as XINJE-XC5-32T-E; the first proximity sensor 9 and the second proximity sensor 52 can specifically be models such as LMB-3002LA; the stroke adjustable cylinder 6 can be a model such as SDAJ25X100.) -50 (with magnet) and other models; the third pusher cylinder 27 used can be of model KMAL25X225SCA, etc.; when the first polishing motor 13 starts, it will drive the transmission shaft. After the transmission shaft rotates, it will drive the transmission belt to move through the bearing seat on the transmission shaft. After the transmission belt rotates, it will drive the single shaft and the first polishing drive wheel 11 to rotate through the bearing seat on the single shaft of the first polishing drive wheel 11. After the first polishing drive wheel 11 rotates, it will drive the first polishing sand belt 16 to move. After the first polishing sand belt 16 moves, it will drive the first polishing driven wheel 12 and the first correction wheel 14. The first polishing belt 16 rotates, causing it to move in a cycle. When the second polishing motor 35 is powered on, it drives the second polishing drive wheel 33 to rotate. The rotation of the second polishing drive wheel 33 drives the second polishing belt 38 to move. During the movement of the second polishing belt 38, it drives the second polishing driven wheel 34 and the second correction wheel 36 to rotate, thus enabling the second polishing belt 38 to move in a cycle. At the same time, the controller 2 controls the second pushing cylinder 45 to start forward for a certain period of time, so that the second pushing cylinder 45 drives the second pushing component 46 towards the feeding seat 7. The second pusher cylinder 45 moves the second pusher component 46 to its maximum displacement position. When this position is reached, the fourth position magnetic induction switch is activated and generates an electrical signal to the controller 2, which stores the signal as signal A. Then, the controller 2 controls the second pusher cylinder 45 to start in reverse, causing the second pusher cylinder 45 to move the second pusher component 46 back to its initial position. When the second pusher component 46 returns to its initial position, the fourth origin magnetic induction switch is activated and generates an electrical signal to the controller 2, which stores the signal as signal B.

[0033] At this point, the keyed locks that need polishing can be placed flat on the loading conveyor belt 50 with the lock beam facing the loading seat 7 (the locks can be placed on the loading conveyor belt 50 manually or by a robotic arm). Then, the loading motor 49 is started. After starting, the loading motor 49 drives the loading drive shaft 47 to rotate. The rotation of the loading drive shaft 47 then moves the loading conveyor belt 50 towards the loading seat 7. During the movement of the loading conveyor belt 50, the keyed locks move along with it, and the loading driven shaft 48 also rotates. The loading drive shaft 47 and the loading driven shaft 48... When the rotating shaft 48 rotates simultaneously, the feeding conveyor belt 50 will move in a cycle. When the feeding conveyor belt 50 moves the keyed lock to the opposite side of the unloading seat 7, the side of the lock will be in contact with the side of the feeding limit stop 51, so that the feeding limit stop 51 can block and limit the lock from the side. At the same time, the second proximity sensor 52 will generate an electrical signal and send it to the controller 2. After receiving the electrical signal sent by the second proximity sensor 52, the controller 2 will first store it as signal C and control the feeding motor 49 to stop, so that the keyed lock and the feeding conveyor belt 50 stop moving. The controller 2 then determines whether signals A and B were previously stored. If signals A, B, and C are not stored simultaneously in the controller 2, the controller 2 will not control the first pusher cylinder 43 to start. If signals A, B, and C are stored simultaneously in the controller 2, the controller 2 will control the first pusher cylinder 43 to start and clear the previously stored signals A, B, and C. The first pusher cylinder 43 pushes the first pusher component 44 towards the discharge seat 7. As the first pusher component 44 moves, it will push the key located on the feeding conveyor belt 50 opposite the discharge seat 7. The lock with the key moves together towards the feeding seat 7 (the end face of the first pusher 44 is provided with a groove for the key to pass through, so that the first pusher 44 can stably push the lock to move), and finally the lock with the key is stably pushed onto the feeding seat 7 through the guide seat 4; when the lock with the key is pushed onto the feeding seat 7, because the guide seat 4 is provided with a through hole 5 for the key to pass through, the lock body part of the lock is stably stopped on the feeding seat 7, and the key on the lock will be perpendicular to the through hole 5; at the same time, the first proximity sensor 9 on the feeding seat 7 will send a signal to the controller 2, and the controller 2 will be within 0.2~0.Three milliseconds later, the first pushing cylinder 43 is controlled to move the first pushing component 44 away from the dispensing seat 7 and return to the initial position. (After the first pushing cylinder 43 returns to the initial position, the third origin magnetic induction switch will send an electrical signal to the controller 2, which will store it as signal D and control the transfer device to start, so that the transfer device continues to push the subsequent lock forward. When the subsequent lock moves to the opposite side of the dispensing seat 7, the second proximity sensor 52 will generate an electrical signal and send it to the controller 2, which will store it as signal C. However, since the controller 2 does not store signals A and B at this time, the controller 2...) (The controller does not control the start of the first pushing cylinder 43); after 0.2 to 0.3 milliseconds, the controller 2 controls the start of the adjustable stroke cylinder 6, causing the adjustable stroke cylinder 6 to move the feeding seat 7 upward. During this upward movement, the adjustable stroke cylinder 6 simultaneously moves the lock upward, ultimately causing the top surface of the lock to form an arc-shaped contact with the first polishing sand belt 16. (At this time, the first positioning magnetic induction switch on the adjustable stroke cylinder 6 sends a signal E to the controller 2, which then controls the adjustable stroke cylinder 6 to pause for a certain period of time). This allows the rotating first polishing sand belt 16 to perform the first polishing operation on the lock.

[0034] After the first polishing is completed (the time of the first polishing is controlled by adjusting the pause time of the adjustable stroke cylinder 6), the controller 2 controls the adjustable stroke cylinder 6 to move the unloading seat 7 and the lock that has completed the first polishing work downwards, so that the lock separates from the first polishing sand belt 16; after the adjustable stroke cylinder 6 returns to the initial position, the first origin magnetic induction switch on the adjustable stroke cylinder 6 will send a signal F to the controller 2, and the controller 2 will determine that the adjustable stroke cylinder 6 has returned to the initial position; at this time, the controller 2 will first control the tilting platform to translate the air After cylinder 19 is activated for a certain period of time, it causes the tilting platform translation cylinder 19 to push the tilting base 18 towards the unloading seat 7. Because there are limiters on the movement path of the tilting base 18, when the tilting base 18 contacts the limiters, it will stop moving forward. At this time, the locking beam of the lock on the unloading seat 7 just enters between the two locking beam clamping members 24. Then, the controller 2 controls the tilting platform clamping cylinder 23 to start. After the tilting platform clamping cylinder 23 starts, it will drive the two locking beam clamping members 24 to move closer together, thereby causing the two locking beam clamping members 24 to move closer together. The locking beams of the lock are clamped. After the two locking beam clamping parts 24 clamp the locking beams, the controller 2 controls the tilting platform lifting cylinder 20 to start, causing the tilting platform lifting cylinder 20 to drive the tilting translation seat 21 to move upward. The upward movement of the tilting translation seat 21 will drive the tilting platform clamping cylinder 23, the rotary motor 22, and the clamped lock to move upward together. After the lock is completely separated from the unloading seat 7 and there is enough space between the lock and the unloading seat 7 for the lock to tilt, the controller 2 then controls the rotary motor 22 to start for a certain period of time, so that the rotary motor 22 restarts. Within a certain time, the rotating seat, the tilting platform clamping cylinder 23 fixedly installed on the rotating seat, and the clamped lock rotate together and rotate 180 degrees. After the starting time of the rotating motor 22 is up, the controller 2 controls the rotating motor 22 to stop, and then controls the tilting platform lifting cylinder 20 to start again, so that the tilting platform lifting cylinder 20 can drive the tilting translation seat 21 to move downward. The tilting translation seat 21 moving downward will drive the tilting platform clamping cylinder 23, the rotating motor 22, and the clamped lock to move downward together, and finally make the lock return to the feeding seat 7.

[0035] At this point, the first proximity sensor 9 on the unloading platform 7 will send another electrical signal to the controller 2. The controller 2 will first stop the tilting platform lifting cylinder 20 and the tilting platform clamping cylinder 23, causing the locking beam clamping member 24 to release the locking beam. Then, the controller 2 will start the tilting platform translation cylinder 19, causing the tilting platform translation cylinder 19 to move the tilting base 18 away from the unloading platform 7, thereby causing the tilting base 18 to separate the locking beam clamping member 24 from the lock and finally return to the initial position. After the tilting platform translation cylinder 19 returns to the initial position, the controller 2 will then control the stroke adjustable cylinder 6. The adjustable-stroke cylinder 6 moves the material feeding seat 7 upwards, simultaneously moving the lock upwards as well. This causes the top surface of the lock to align with the arc surface of the first polishing belt 16, repeating the first polishing operation. After the second polishing, the controller 2 again controls the adjustable-stroke cylinder 6 to move the material feeding seat 7 and the lock (which has completed the second polishing) downwards, separating the lock from the first polishing belt 16 and returning it to its initial position. Once the lock and material feeding seat 7 have returned to their initial positions, the controller 2 will receive... Upon receiving signal F, controller 2 first stops the adjustable stroke cylinder 6, then synchronously starts the second pusher cylinder 45 and the positioning cylinder 30. After starting, the second pusher cylinder 45 drives the second pusher component 46 towards the middle channel 8, allowing it to push the lock that has completed two polishing operations from the feeding seat 7 into the middle channel 8. When the second pusher cylinder 45 reaches its maximum forward position, the fourth positioning magnetic induction switch on the second pusher cylinder 45 sends a signal A to controller 2. Controller 2 then stops the second pusher cylinder 45, causing it to drive the second pusher cylinder 45 to move towards the middle channel 8. The pusher 46 returns to its initial position. After the second pusher 46 returns to its initial position, the controller 2 will receive signal B again. Combined with the signal C sent from the first pusher cylinder 43, the controller 2 will control the first pusher cylinder 43 to start again and clear the stored signals A, B and C, so that the first pusher cylinder 43 can perform the loading of the next lock. Based on the first polishing process of the previous lock, the controller 2 will control the transfer device, the first pusher device, etc. to start and stop in sequence to perform the previous loading, first polishing, flipping and second polishing.

[0036] When four locks are pushed into the middle channel 8 in sequence, and after the fifth lock is pushed into the middle channel, the subsequently pushed locks will push the preceding locks towards the third pusher seat 25, causing the foremost lock to be pushed onto the clamping base 26. At this time, the controller 2 controls the third pusher cylinder 27 to start. After the third pusher cylinder 27 starts, it will push the clamping moving seat along the mounting part towards the second polishing device. When the clamping moving seat moves, it will push the clamping top seat 28 through the position rotatably connected to the clamping top seat 28, so that the clamping top seat 28 can rotate along the position rotatably connected to the mounting part, thereby allowing the end of the clamping top seat 28 located directly above the clamping base 26 to clamp. The base 26 moves in one direction, ultimately causing the clamping top seat 28 and the clamping base 26 to clamp the lock vertically. As the third pusher cylinder 27 continues to operate, the clamping moving seat and the mounting piece abut against each other and cease moving. This causes the third pusher cylinder 27, through the clamping moving seat, the mounting piece, and the clamping top seat 28, to push the third pusher seat 25 towards the second polishing device, ultimately moving the lock between the two second polishing sand belts 38. (A front positioning piece and a rear positioning piece are respectively provided at both ends of the path of the third pusher seat 25. When the third pusher seat 25 pushes the lock between the two second polishing sand belts 38, the third pusher seat 25 contacts the front positioning piece, utilizing the interaction between the front positioning piece and the third pusher seat 25...) The interaction prevents the third pusher cylinder 27 from pushing the third pusher seat 25 forward, allowing the lock to remain stably between the two second polishing sand belts 38. When the third pusher seat 25 returns to its initial position, directly opposite the middle channel 8, it contacts the rear positioning component, preventing it from moving backward and ensuring the clamping base 26 is positioned directly opposite the middle channel 8. When the lock is moved between the two second polishing sand belts 38, the second positioning magnetic induction switch on the third pusher cylinder 27, used to detect the upper limit of the third pusher cylinder 27's movement, sends a signal G to the controller 2. The controller 2 then controls the third pusher cylinder 27 to pause for a certain period of time and controls... The auxiliary push cylinder 39 is activated, causing it to push the auxiliary clamping seat 40 between the two second polishing sand belts 38. This allows the second polishing sand belts 38 to better fit the side of the lock for the third polishing operation. After the third polishing operation is completed, the controller 2 first controls the auxiliary push cylinder 39 to move the auxiliary clamping seat 40 away from the lock, separating it from the lock and thus separating the second polishing sand belts 38 from the lock. Then, the controller stops the auxiliary clamping cylinder 39, and the third push cylinder 27 is activated, causing it to move the lock back and ultimately return the clamping base 26 and the polished lock to their initial positions.During the retraction of the third pusher cylinder 27, it first drives the clamping moving seat to move back, applying a backward pulling force to the clamping top seat 28. This causes the clamping top seat 28 to rotate upward around the position where it is rotatably connected to the mounting component, ultimately releasing the lock between the clamping top seat 28 and the clamping base 26. As the third pusher cylinder 27 continues to pull, the rear end of the clamping moving seat abuts against the mounting component, thus enabling the third pusher cylinder 27 to stably complete the action of driving the third pusher seat 25 to move back through the mounting component, the clamping moving seat, and the clamping top seat 28. When the third pusher base 25 and the lock return to their initial positions, the second origin magnetic induction switch on the third pusher cylinder 27 sends a signal H to the controller 2. The controller 2 determines that the movement is in place and controls the third pusher cylinder 27 to stop. When the second pusher cylinder 45 restarts in the previous process, moving the lock that has completed two polishing operations towards the middle channel 8, the lock at the front of the middle channel 8 will be pushed onto the clamping base 26 by the lock behind it. At the same time, the lock that has been pushed will push the lock that has completed three polishing operations onto the storage platform 29. In addition, because the positioning cylinder 3 The second pusher cylinder 45 and the positioning cylinder 30 work synchronously. After the positioning cylinder 30 is activated, it extends a certain length towards the clamping base 26, thereby positioning the lock on the side. Finally, the lock pushed in earlier stops accurately on the clamping base 26, and the lock pushed out of the clamping base 26 is stably positioned on the storage platform 29. When the third pusher cylinder 27 pushes the third pusher seat 25 to move towards the second polishing device, the support block 32 on the side of the third pusher seat 25 also moves together. The support block 32 moves from the suspended end of the storage platform 29 towards the storage platform. As the support block 32 moves, the support below the suspended end of the storage platform 29 decreases, causing the suspended end of the storage platform 29 to automatically rotate downwards. This causes the storage platform 29 to change from a horizontal to an inclined position, allowing the lock on the storage platform 29 to automatically slide into the unloading channel 3, completing the unloading process. When the third pusher seat 25 moves back, the support block 32 pushes the storage platform 29 upwards from below, changing the storage platform 29 from an inclined position back to a horizontal position to reposition the lock, completing the entire process.

[0037] When the feeding seat 7 drives the lock to contact the first polishing belt 16 for polishing, the first polishing belt 16 rotates along the middle channel 8 towards the second pushing device. A stop 10 is provided on the side of the feeding seat 7 near the second pushing device. This stop 10 blocks the movement of the lock during the polishing process, preventing the lock from slipping off the feeding seat 7 due to friction and ensuring operational stability. During the operation of the first polishing belt 16 and the second polishing belt 38, it is necessary to activate the external dust removal devices connected to the first dust suction hood 17 and the second dust suction hood 42, respectively, to ensure the smooth operation of the first polishing belt 16 and the second polishing belt 38. The debris generated during polishing of belt 38 is collected and processed by the first dust hood 17 and the second dust hood 42, preventing debris from scattering everywhere, facilitating subsequent cleaning, and ensuring a comfortable working environment. Because the end of the intermediate channel 8 is equipped with an elastic catch 54, when the foremost lock is pushed onto the clamping base 26, the subsequent locks are pushed to the front of the intermediate channel 8. The elastic catch 54 provides a certain limiting and buffering effect on the top surface of the locks, ensuring that the foremost lock can be stably pushed onto the third pusher seat 25, while the subsequent lock can be stably held at the front of the intermediate channel 8 awaiting further pushing, ensuring operational stability. Furthermore, the entire frame is equipped with... The protective cover houses the first and second polishing devices, preventing direct contact between the user and these devices and ensuring operational stability. The first shock absorber 15 counteracts the vibrations generated by the first polishing belt 16 during polishing, preventing vibration transmission to the feeding seat 7 and thus avoiding lock position misalignment, which would affect the contact stability between the lock body and the first polishing belt 16, ensuring polishing effectiveness. The first alignment wheel 14 is mounted on the adjusting seat via a hinge, and the adjusting seat and the first alignment wheel 14 are connected by a U-shaped groove. The adjusting seat also has adjusting bolts that contact the first alignment wheel 14. With these three components working together... This design allows the first alignment wheel 14 to have a certain range of vertical movement, enabling real-time adjustment of its position during polishing and preventing the first polishing belt 16 from detaching from it. Furthermore, the top surface of the first alignment wheel 14 is an upward-convex arc surface, ensuring that the first alignment wheel 14, the first polishing drive wheel 11, and the first polishing driven wheel 12 work together to maintain the first polishing belt 16 under tension. This prevents upward-convex gaps between the first polishing belt 16 and the lock body, ensuring a good polishing effect. In this application, the end of the stroke-adjustable cylinder 6 is equipped with an adjusting nut, allowing adjustment of the stroke of the cylinder.In this application, the start time of the auxiliary push cylinder 39 can be adjusted, and the time for the third polishing of the lock can be adjusted by adjusting the start time of the auxiliary push cylinder 39; in this application, multiple adjusting bolts are provided between the auxiliary clamping seat 40 and the auxiliary push cylinder 39, so that the position of the auxiliary clamping seat 40 on the X-axis and Y-axis can be adjusted by rotating the adjusting bolts, so that the auxiliary clamping seat 40 can better fit the second polishing sand belt 38 with the lock;

[0038] In this application, the controller 2 controls the start-up of the adjustable stroke cylinder 6, the tilting platform translation cylinder 19, the tilting platform lifting cylinder 20, the tilting platform clamping cylinder 23, the third pushing cylinder 27, the auxiliary pushing cylinder 39, the first pushing cylinder 43, and the second pushing cylinder 45. This is achieved by the controller 2 energizing the intermediate relays corresponding to each cylinder. When the intermediate relays are energized, the solenoid valves on the corresponding air supply pipes open, allowing the air supply pipes to energize the corresponding cylinders, thus starting the cylinders and moving the corresponding components. Conversely, the control of restarting or stopping the cylinders mentioned in this application is achieved by the controller 2 de-energizing the corresponding intermediate relays. After the intermediate relays are de-energized, the corresponding solenoid valves... The air supply pipe stops supplying air to the cylinder, causing the components on the cylinder to return to their initial position. During the initial operation, as the second pusher cylinder 45 pushes the first polished lock into the intermediate channel 8, the positioning cylinder 30 also operates synchronously but does not contact the lock. As locks continue to be pushed in, four locks are stored in the intermediate channel 8. At this time, the positioning cylinder 30 performs a total of four empty movements, including the initial sequence. When the second pusher cylinder 45 pushes the next lock into the intermediate channel, the positioning cylinder 30 contacts the lock to complete its first movement. The third pusher cylinder 27 then pushes the clamping top... During the process of clamping the lock by the clamping base 26 and the clamping seat 28, the end of the clamping top seat 28 connected to the clamping support seat 60 rotates around the second pivot. Meanwhile, the bent end of the clamping top seat 28 connected to the U-shaped connecting seat not only rotates around the first pivot but also moves the U-shaped connecting seat upwards. After the clamping top seat 28 and the clamping base 26 clamp the lock, the entire U-shaped connecting seat only moves upwards by 0.1 to 0.3 millimeters. Simultaneously, the third pusher cylinder 27 pushes the U-shaped connecting seat forward along the top surface of the clamping support seat 60 by 6 to 7 millimeters. Because the upward and forward movements are very small, they do not cause the piston rod of the third pusher cylinder 27 to tilt upwards at a large angle. Overall, the pushing direction of the third pusher cylinder 27 is still parallel to the moving direction of the third pusher seat 25. In addition, the first rotating shaft and the clamping top seat 28 are fitted with clearance, the second rotating shaft and the clamping support seat 60 are fitted with clearance, the second rotating shaft and the clamping top seat 28 are fitted with clearance, and the first rotating shaft and the U-shaped connecting seat are fitted with clearance, so there will be no movement interference. When the third pusher cylinder 27 drives the clamping top seat 28 and the clamping base 26 to release the lock and return it to the initial position, the U-shaped groove 61 on the clamping support seat 60 will limit the clamping base 28 after it flips over, so that the third pusher cylinder 27 can drive the third pusher seat 25 to move back.
