Description

Technical Field

[0001] This invention relates to the field of chemical fiber cake production and manufacturing, and in particular to a device for transferring the cake. Background Technology

[0002] A winding machine is a device used to wind chemical fibers into filament cakes, which are hollow discs. A filament cake receiving box is a carrier for receiving filament cakes in batches, comprising a base and several filament cake tubes horizontally mounted above the base. In use, an AGV transports the filament cake receiving box to the output end of the winding machine, aligning the filament cake tubes with the output end. The output end then sequentially strings the produced filament cakes onto the filament cake tubes. When the filament cake tubes are full, the AGV transfers the filament cake receiving box to a filament transport vehicle, whereby the filament cakes on the tubes are manually transferred to the racks of the filament transport vehicle. Utility model patents with publication numbers CN202809083U and CN204210508U disclose a similar filament cake receiving box and filament transport vehicle.

[0003] To address the problems of time-consuming and labor-intensive manual handling of yarn cakes and the health risks associated with the workshop environment, a device for transferring yarn cakes has been introduced to the market. The device includes a frame with a placement platform for holding the yarn storage box and a pusher block above the platform. A multi-axis motion platform drives the pusher block. A robotic arm and an unloaded yarn transport cart are located on one side of the frame. In operation, the AGV places the yarn storage box on the placement platform. The multi-axis motion platform then drives the pusher block to abut against the rear end of the last yarn cake on the yarn cake tube, pushing the entire string of yarn cakes forward. After each unit distance, the robotic arm uses its grippers to remove the yarn cake at the front of the yarn cake tube and hangs it on the rack of the yarn transport cart. By repeating these steps, all the yarn cakes on the yarn cake tube can be transferred to the yarn transport cart, eliminating the need for manual handling.

[0004] To ensure the precise alignment between the pusher block, the wire cake tube, and the wire cake itself, the aforementioned equipment for transferring wire cakes requires increased positioning accuracy between the wire cake storage box and the placement platform. Therefore, several positioning seats are typically installed on the placement platform. These seats surround the wire cake storage box and abut against its bottom sidewalls. The upper surface of each positioning seat has a guide ramp. When the AGV places the wire cake storage box on the placement platform, if there is a horizontal deviation, its bottom side will abut against the guide ramp of one row of positioning seats. As the wire cake storage box is lowered, the guide ramp corrects its horizontal deviation until it lands precisely in the designated placement area on the platform. During this process, the bottom side of the wire storage box will scrape against the guide slope. Since both the positioning seat and the bottom of the wire storage box are made of metal and have similar hardness, rigid collisions and scraping will occur when they come into contact. Over time, this can easily cause wear on the bottom of the wire storage box, affecting subsequent placement and accurate positioning, and increasing the maintenance cost of the wire storage box. Therefore, it still needs to be improved. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for transferring yarn cakes. By reducing the hardness of the guide pad, the wear during the mating of the yarn cake storage box and the guide ramp can be effectively reduced, thereby increasing the accuracy of the yarn cake storage box and extending its service life.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A device for transferring yarn cakes includes a placement platform for placing a yarn cake storage box, a positioning seat on the upper surface of the placement platform, and a guide slope on the upper end of the positioning seat. A guide pad is attached to the guide slope, and the hardness of the guide pad is less than that of the bottom of the yarn cake storage box. A shock absorber is provided on the lower surface of the guide pad, which floats in a direction perpendicular to the guide slope. An elastic drive mechanism is provided on the positioning seat to make the shock absorber tend to pop out in its own floating direction. The guide pad has a plurality of oil outlet holes, and the shock absorber has a plurality of oil guide holes for the plurality of oil outlet holes to be connected one by one. An extrusion plate is provided on the positioning seat below the shock absorber. An oil storage buffer is clamped between the extrusion plate and the shock absorber for storing lubricating oil and forming an elastic support force between the extrusion plate and the shock absorber. An oil storage buffer is provided with an oil supply mechanism and an oil supply mechanism, and the oil supply mechanism is connected to the oil guide holes.

[0008] When the bottom of the wire storage box is pressed against the guide pad to make the shock absorber overcome the elastic force of the elastic drive mechanism, the oil storage buffer is squeezed to drive the oil supply mechanism to inject lubricating oil into the oil outlet, thereby causing the oil outlet to leak oil; when the wire storage box is disengaged from the guide pad to make the shock absorber reset, the oil storage buffer rebounds to absorb the lubricating oil in the oil supply mechanism.

[0009] By adopting the above solution, a guide pad with low hardness is installed on the guide slope, which can effectively reduce wear caused by rigid collision and scraping between the bottom of the wire storage box and the metal positioning seat, thereby extending the service life of the wire storage box and reducing maintenance costs. Further, a floating shock-absorbing seat and elastic drive mechanism are installed, allowing the guide pad to retract appropriately when compressed, thus buffering and absorbing vibrations and further reducing impact and damage to the wire storage box. The cooperation between the oil outlet, oil guide hole, oil storage buffer, oil supply mechanism, and oil supply mechanism automatically provides lubricating oil to the contact surface during the compression of the guide pad by the wire storage box, forming a lubricating layer and further reducing sliding friction and frictional damage between the bottom of the wire storage box and the guide pad. When the compression is released, the shock-absorbing seat and oil storage buffer rebound to draw lubricating oil from the oil supply mechanism, thereby achieving automatic oil supply.

[0010] Preferably, the oil storage buffer is an elastic porous body with continuous through pores, in which lubricating oil is adsorbed, and the surface of the oil storage buffer is covered with an impermeable membrane to prevent lubricating oil leakage.

[0011] By adopting the above scheme, the oil storage buffer is designed as an elastic porous body with continuous through-pores, which enables it to have good elastic buffering capacity and efficient lubricating oil adsorption and storage capacity. The anti-permeability membrane covering the surface can effectively prevent lubricating oil from leaking from the non-working surface of the oil storage buffer, ensuring that the lubricating oil can seep out according to the preset path (i.e., the oil guide hole and the oil outlet hole) when under pressure, thereby improving lubrication efficiency and keeping the equipment clean.

[0012] Preferably, the oil supply mechanism includes a plurality of oil guide columns disposed on the upper surface of the oil storage buffer and inserted into a plurality of oil guide holes. Each oil guide column is an elastic porous body with continuous through-holes and an oil guide tube is sleeved on its outer side.

[0013] By adopting the above scheme, an oil guide column with the same material and principle as the oil storage buffer is selected as the oil supply mechanism, and its outer circumference is covered by an oil guide pipe. This ensures that the lubricating oil is efficiently and directionally transported from the oil storage buffer to the oil guide hole, while preventing the lubricating oil from leaking from the side wall of the oil guide column during the transportation process, thus ensuring the sealing and accuracy of the oil supply path.

[0014] Preferably, a silicone cross valve is installed inside the oil guide hole, and the silicone cross valve abuts against one end of the oil guide column near the oil outlet.

[0015] By adopting the above solution, a silicone cross valve is installed inside the oil guide hole. When the silicone cross valve is normally closed, it effectively prevents dust and impurities from entering the oil supply system through the oil outlet and causing contamination or blockage. When the oil reservoir is compressed, lubricating oil can be forced open by the oil guide column to supply oil to the oil outlet. When the compression is released, the valve automatically closes again. Supported by the oil guide column, the silicone cross valve cannot open in reverse, thus acting as a one-way valve. This effectively prevents the suction force of the oil reservoir during oil intake from causing reverse air intake by the oil guide column, thereby improving oil replenishment efficiency and enhancing the long-term reliability of the system.

[0016] Preferably, the oil supply mechanism includes an oil guide column 2 disposed on the oil storage buffer, an oil guide pipe 2 sleeved on the oil guide column 2, an oil storage box disposed on the extrusion plate, and a connecting oil pipe connecting the oil guide pipe 2 and the oil storage box to realize the oil passage connection between the two.

[0017] Using the above scheme, the second oil guide column, the second oil guide pipe, the oil reservoir, and the connecting oil pipe constitute an external lubricating oil replenishment channel. When the internal oil volume of the oil reservoir buffer decreases due to continuous oil supply, it can automatically draw lubricating oil from the oil reservoir through capillary action and pressure difference to replenish it, thereby achieving long-term self-sustaining oil supply of the oil supply system and reducing the frequency of manual oiling and maintenance burden.

[0018] Preferably, the second oil guide pipe is equipped with a one-way valve assembly that allows lubricating oil to enter the second oil guide pipe in one direction.

[0019] By adopting the above solution, a one-way valve assembly is installed in the second oil guide pipe to ensure that the lubricating oil flows only from the oil storage box to the oil storage buffer, effectively preventing the lubricating oil from flowing back during the extrusion or static conditions of the oil storage buffer. This maintains a stable oil reserve in the oil storage buffer and the internal oil pressure of the oil supply system, thereby ensuring reliable oil supply for each extrusion.

[0020] Preferably, the oil reservoir has an oil filling port on the upper side, and a filter screen is installed on the oil filling port.

[0021] By adopting the above solution, a filler port is provided on the oil reservoir, facilitating the periodic addition of lubricating oil. The filter installed at the filler port effectively prevents dust and fiber debris from entering the oil reservoir during refueling or daily operation, thus ensuring the cleanliness of the lubricating oil and protecting the entire oil supply and lubrication system.

[0022] Preferably, an oil receiving box is provided on the inner side of the positioning seat, with the upper opening of the oil receiving box facing the downstream end of the guide slope to receive lubricating oil. A pad for receiving the wick storage box is provided on the upper surface of the placement platform and inside the oil receiving box. The upper surface of the pad is higher than the upper opening of the oil receiving box and lower than the downstream end of the guide slope.

[0023] Using the above solution, when the wire storage box scrapes against the guide pad, the excess oil scraped off can flow along the side wall of the positioning seat into the oil receiving box, preventing lubricating oil from dripping and contaminating the placement platform and the ground. By raising the wire storage box with a pad, it is possible to prevent the wire storage box from squeezing the oil receiving box when it falls, thus avoiding damage to the oil receiving box.

[0024] Preferably, a movable groove for the shock absorber seat to float is provided on the guide slope, and a limit block is provided on the inner side wall of the movable groove; when the shock absorber seat abuts against the limit block, the lower edge of the upper surface of the guide pad is flush with the lower edge of the opening of the movable groove.

[0025] Using the above scheme, the movable groove can provide precise guidance for the floating of the shock absorber seat and limit its maximum downward pressure distance through the limiting block. When the shock absorber seat abuts the limiting block, the upper edge of the guide pad is flush with the edge of the movable groove opening. This design ensures that the guide pad can smoothly connect with the side wall of the positioning seat in the downward pressure state, avoiding the formation of protrusions or pits that would interfere with the normal sliding of the wire storage box, and ensuring the smoothness of the positioning and guiding process.

[0026] Preferably, the elastic drive mechanism is provided in four sets and is located at the four corners of the shock absorber. Each set of elastic drive mechanism includes a guide rod located on the side of the shock absorber away from the guide pad, a connecting seat located on the inner side wall of the movable groove for the guide rod to slide along the floating direction of the shock absorber, a compression spring sleeved on the guide rod and generating elastic support between the shock absorber and the connecting seat, and an anti-detachment component located at the end of the guide rod to prevent the guide rod from detaching from the connecting seat.

[0027] Using the above scheme, the elastic drive mechanisms located at the four corners of the shock absorber ensure the uniformity of force distribution on the shock absorber and enhance its elastic support. The guide sliding fit between the guide rod and the connecting seat ensures the floating accuracy of the shock absorber; even under eccentric pressure from the wicking box, it maintains stable vertical floating and quickly and accurately resets after the guide pad releases pressure. The anti-detachment component prevents the guide rod from dislodging from the connecting seat, thus ensuring the stability of the elastic drive mechanism.

[0028] Preferably, the guide shim is fixed to the shock absorber seat by screws.

[0029] Using the above solution, the guide shim is fixed to the shock absorber base with screws, making the connection simple, reliable, and easy to disassemble. When the guide shim wears out due to long-term use, the old shim can be easily removed and replaced, greatly reducing the difficulty and cost of maintaining and replacing this vulnerable component, and further improving the maintainability of the equipment.

[0030] This invention, by employing the above technical solutions, achieves significant technical effects: The low-hardness guide pads on the guide slope effectively reduce wear caused by rigid collisions and scraping between the bottom of the wire storage box and the metal positioning seat, thereby extending the service life of the wire storage box and reducing maintenance costs. Furthermore, the floating shock-absorbing seat and elastic drive mechanism allow the guide pads to retract appropriately under pressure, providing cushioning and vibration absorption, further reducing impact and damage to the wire storage box. The coordination between the oil outlet, oil guide hole, oil storage buffer, oil supply mechanism, and oil supply mechanism automatically provides lubricating oil to the contact surface during the compression of the guide pads by the wire storage box, forming a lubricating layer and further reducing sliding friction and frictional damage between the bottom of the wire storage box and the guide pads. When the compression is released, the shock-absorbing seat and oil storage buffer rebound to draw lubricating oil from the oil supply mechanism, thus achieving automatic oil supply.

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0049] like Figures 1 to 16As shown in the figure, this embodiment discloses a device for transferring yarn cakes, including a frame 33 and a placement platform 2 disposed on the frame 33 for placing a yarn cake 1. Multiple positioning seats 3 are fixed on the upper surface of the placement platform 2, and the multiple positioning seats 3 are evenly arranged around the bottom of the yarn cake 1, so that they can evenly cover the four sides of the bottom of the yarn cake 1. The inner side of each positioning seat 3 abuts against the bottom side of the yarn cake 1, thereby achieving precise positioning and preventing positional deviation. The upper end of the positioning seat 3 has a guide slope 4 facing the yarn cake 1, thereby guiding the yarn cake 1 to fall precisely into the designated area of ​​the placement platform 2.

[0050] A horizontal yarn cake tube 32 is fixedly mounted on the upper side of the yarn storage box 1, and multiple yarn cakes 34 are strung on the yarn cake tube 32. A multi-axis motion platform 35 is provided on the top of the frame 33, and a push block 37 is fixed to the execution end 36 of the multi-axis motion platform 35. The lower surface of the push block 37 has an arc groove 38 adapted to the curvature of the upper surface of the yarn cake tube 32. A robotic arm 39 fixed to the ground is provided on one side of the frame 33, and an internal support gripper 40 is provided at the execution end of the robotic arm 39. A yarn transport carriage 41 is provided on the side of the robotic arm 39 away from the frame 33, and a hanging bracket 42 for hanging the yarn cakes 34 is fixed on the side of the yarn transport carriage 41.

[0051] To ensure sufficient space for the AGV to pick up and put down the wire storage box 1, a rigid chain lift 43 is fixed to the bottom of the frame 33. The lifting end of the lift is fixed to the bottom of the placement platform 2 to achieve smooth lifting and lowering of the placement platform 2.

[0052] During operation, the placement platform 2 is first lowered via a rigid chain lift 43 to ensure sufficient space above it. Then, an AGV transports the spool storage box 1, loaded with yarn cakes 34, to the placement platform 2 and lowers it. During lowering, the guide ramp 4 on the positioning seat 3 corrects the deviation, ensuring the bottom of the spool storage box 1 falls precisely into the designated area of ​​the placement platform 2. After placement, the multi-axis motion platform 35 drives the pusher block 37 to move behind the last yarn cake 34 on the yarn cake tube 32, and after coaxially aligning with the yarn cake tube 32 in the arc groove 38, it abuts against the rear end face of the yarn cake 34. Next, the multi-axis motion platform 35 drives the pusher block 37 forward, pushing the entire string of yarn cakes 34 by half the thickness of a yarn cake 34 in a single push. With each unit push, the yarn cake 34 at the very front of the yarn cake tube 32 is partially suspended in the air. At this point, the robotic arm 39 can extend the inner support gripper 40 into the suspended central hole 44 of the yarn cake 34 and press against the side wall of the central hole 44, thereby grasping the yarn cake 34. Finally, the robotic arm 39 removes the grasped yarn cake 34 from the yarn cake tube 32 and hangs it on the hanger 42 of the yarn transport vehicle 41. Repeating the above steps completes the transfer of the yarn cake 34. After the yarn cake 34 is transferred, the placement platform 2 is lowered again, and the empty yarn storage box 1 is unloaded from the placement platform 2 by the AGV.

[0053] The above control process can be implemented using the PLC's built-in program, which is common knowledge in this field and will not be elaborated here.

[0054] To prevent the wire storage box 1 from scraping against the guide slope 4 of the positioning seat 3 during lateral correction, a guide pad 5 is fitted onto the guide slope 4. The guide pad 5 is preferably made of nylon 6 or nylon 66, which has a lower hardness than the bottom of the wire storage box 1 and strong wear resistance, thus improving the service life of the guide pad 5. A shock-absorbing seat 6 that floats perpendicular to the guide slope 4 is provided on the lower surface of the guide pad 5. The guide pad 5 is fixed to the shock-absorbing seat 6 by countersunk screws 31. Four screws 31 are provided and located at the four corners of the guide pad 5. A movable groove 25 for the shock-absorbing seat 6 to float is provided on the guide slope 4. Limiting blocks 26 are fixed to the inner wall of the movable groove 25. Two sets of limiting blocks 26 are provided and located on both sides of the shock-absorbing seat 6. When the shock absorber 6 abuts against the limiting block 26, the lower edge 45 of the upper surface of the guide pad 5 is flush with the lower edge 46 of the opening of the movable groove 25, thereby ensuring that the guide pad 5 can smoothly connect with the inner wall of the positioning seat 3 after being fully pressed down, and avoiding obstruction when the wicking box 1 falls.

[0055] To achieve the cushioning effect of the shock absorber 6, the positioning seat 3 is provided with an elastic drive mechanism 7 to give the shock absorber 6 a tendency to pop out along its own floating direction. Specifically, the elastic drive mechanism 7 is provided in four sets and is located at the four corners of the shock absorber 6. Each set of elastic drive mechanism 7 includes a guide rod 27 fixed to the side of the shock absorber 6 away from the guide pad 5, a connecting seat 28 fixed to the inner wall of the movable groove 25 for the guide rod 27 to slide along the floating direction of the shock absorber 6, a compression spring 29 sleeved on the guide rod 27 and generating elastic support force between the shock absorber 6 and the connecting seat 28, and an anti-detachment component 30 fixed to the end of the guide rod 27 to prevent the guide rod 27 from detaching from the connecting seat 28.

[0056] To achieve self-lubrication of the guide gasket 5 surface, the guide gasket 5 is provided with several oil outlet holes 8, and the shock absorber 6 is provided with several oil guide holes 9 for one-to-one connection of the oil outlet holes 8. An extrusion plate 10 located below the shock absorber 6 is fixedly connected between the two inner sidewalls of the movable groove 25. An oil storage buffer 11 for storing lubricating oil and forming elastic support between the extrusion plate 10 and the shock absorber 6 is clamped between the extrusion plate 10 and the shock absorber 6. The oil storage buffer 11 and the extrusion plate 10 each have clearance grooves 47 at their four corners for accommodating the elastic drive mechanism 7. The oil storage buffer 11 is equipped with an oil supply mechanism and an oil supply system, with the oil supply mechanism connected to the oil guide holes 9.

[0057] In this embodiment, when the bottom of the wire storage box 1 presses against the guide pad 5 to cause the shock absorber 6 to overcome the elastic force of the elastic drive mechanism 7 and press down, the oil storage buffer 11 is compressed to drive the oil supply mechanism to inject lubricating oil into the oil outlet 9, thereby causing oil to seep out of the oil outlet 8 to lubricate the surface of the guide pad 5. When the wire storage box 1 disengages from the guide pad 5 to reset the shock absorber 6, the oil storage buffer 11 rebounds to absorb the lubricating oil in the oil supply mechanism, thereby achieving automatic oil replenishment.

[0058] Specifically, the oil reservoir buffer 11 is an elastic porous body with continuous through pores. Lubricating oil is adsorbed in the pores and is evenly diffused throughout the oil reservoir buffer 11 by means of capillary effect. The surface of the oil reservoir buffer 11 is covered with an anti-permeability membrane 12 to prevent lubricating oil leakage. The anti-permeability membrane 12 is preferably a polytetrafluoroethylene (PTFE) membrane, which has good oil permeability resistance, chemical inertness and flexibility, and can both seal the oil and facilitate the compression of the oil reservoir buffer 11.

[0059] The oil supply mechanism includes several oil guide columns 13 disposed on the upper surface of the oil storage buffer 11 and inserted into several oil guide holes 9. Each oil guide column 13 is an elastic porous body with continuous through-holes and an oil guide tube 58 is sleeved on its outer side. The oil supply mechanism includes a second oil guide column 15 disposed on the oil storage buffer 11, a second oil guide tube 16 sleeved on the second oil guide column 15, an oil storage box 17 fixed to the back of the extrusion plate 10, and a connecting oil pipe 18 connecting the second oil guide tube 16 and the oil storage box 17 to realize the oil passage between the two. Among them, the oil storage buffer 11, the first oil guide column 13 and the second oil guide column 15 are all made of oil-absorbing sponge and are integrally set, and the lubricating oil can be evenly diffused to all parts of the three through capillary effect. The first oil guide tube 58 and the second oil guide tube 16 are both made of polytetrafluoroethylene (PTFE) and are integrally set with the anti-permeation membrane 12, thereby playing a better role in preventing oil penetration. An oil nozzle 48, which communicates with the inner cavity of the oil reservoir 17, is fixed to the side wall of the oil reservoir 17 near the bottom. The connecting oil pipe 18 is preferably made of PU hose, which has better oil resistance, wear resistance and flexibility. Its two ends are respectively interference-fitted to the oil guide pipe 16 and the oil nozzle 48, thereby completing the oil circuit connection between the oil reservoir 17 and the oil storage buffer 11.

[0060] To achieve unidirectional flow of the oil supply mechanism, a silicone cross valve 14 is installed inside the oil guide hole 9. The outer wall of the silicone cross valve 14 is thickened to facilitate its fixation to the inner wall of the oil guide hole 9 with adhesive. The silicone cross valve 14 abuts against the end of the oil guide column 13 near the oil outlet hole 8, thereby preventing it from opening in the reverse direction and thus playing a backflow prevention role.

[0061] To achieve unidirectional flow of the oil supply mechanism, a one-way valve assembly 19 is installed inside the second oil guide pipe 16 to allow lubricating oil to enter the second oil guide pipe 16 in one direction. The one-way valve assembly 19 includes a connecting ring 49 with a fixing ring disposed on the inner wall of the second oil guide pipe 16, an elastic sealing sheet 51 covering the inner end face of the connecting ring 49 to seal the inner hole 50 of the connecting ring 49, and a connecting piece 52 integrally disposed on the elastic sealing sheet 51 and fixed to the connecting ring 49. Among them, the connecting ring 49 and the second oil guide pipe 16 are made of the same material and are integrally disposed. The elastic sealing sheet 51 and the connecting piece 52 are both made of fluororubber, thus having good oil resistance. At the same time, fluororubber and polytetrafluoroethylene have material affinity, so the fixed connection between the connecting piece 52 and the connecting ring 49 can be achieved by using a fluorinated special adhesive.

[0062] To facilitate the addition of lubricating oil to the oil reservoir 17, an oil filling port 20 is provided on the upper side of the oil reservoir 17, and a filter screen 21 is installed on the oil filling port 20. The outer edge of the filter screen 21 is covered with a metal edging 53 that can be attracted by a magnet. The upper surface of the oil filling port 20 is provided with multiple magnetic elements 54 for the metal edging 53 to be attracted by the magnet. The magnetic elements 54 are preferably permanent magnets. The magnetic attraction between the magnetic elements 54 and the metal edging 53 allows for quick installation and removal of the filter screen 21 from the oil filling port 20. When the lubricating oil in the oil reservoir 17 is exhausted, lubricating oil can be added directly to the filter screen 21. The filtered lubricating oil can directly enter the oil reservoir 17 for replenishment, while the filtered impurities remain on the filter screen 21. When there are too many impurities, the filter screen 21 can be removed by overcoming the magnetic force of the magnetic elements 54, cleaned, dried, and then reinstalled magnetically.

[0063] To facilitate the collection of excess oil scraped from the guide gasket 5, an oil collection box 22 is provided on the inner side of the positioning seat 3. The upper opening 23 of the oil collection box 22 faces the downstream end of the guide slope 4 to collect lubricating oil. To facilitate the disassembly and assembly of the oil collection box 22, a slot 55 is provided on the side of the positioning seat 3 near the bottom for the horizontal insertion of the oil collection box 22. The slot 55 and the end of the oil collection box 22 away from the wire storage box 1 both extend horizontally to the outer side of the positioning seat 3. A connecting plate 56 extends horizontally to both ends of the side of the oil collection box 22 away from the wire storage box 1. The connecting plate 56 is fixed to the outer wall of the positioning seat 3 by screw 2 57. When the waste oil in the oil collection box 22 is full, screw 2 57 is removed to release the locking of the connecting plate 56. Then, the oil collection box 22 is pulled out horizontally from the rear of the positioning seat 3 and the waste oil is poured out. Finally, the oil collection box 22 is reinserted and the connecting plate 56 is locked again by screw 2 57.

[0064] To prevent the wire collecting box 1 from hitting the oil receiving box 22 during placement, a pad 24 for supporting the wire collecting box 1 is provided on the upper surface of the placement platform 2 and inside the oil receiving box 22. The upper surface of the pad 24 is higher than the upper opening 23 of the oil receiving box 22 and lower than the downstream end of the guide slope 4. To reduce the scraping between the wire collecting box 1 and the upper surface of the pad 24 during horizontal alignment, a support roller is provided on the upper surface of the pad 24, thereby reducing wear on the wire collecting box 1.

[0065] When the AGV places the wire storage box 1 above the placement platform 2, if the wire storage box 1 has a horizontal deviation, its outer bottom edge will abut against the guide slope 4 of the positioning seat 3 during descent. This overcomes the elastic force of the elastic drive mechanism 7 and the oil storage buffer 11, causing the guide pad 5 and the shock absorber 6 to press down, thereby cooperating with the extrusion plate 10 to compress the oil storage buffer 11. After the oil storage buffer 11 is compressed, the lubricating oil stored inside it will break through the silicone cross valve 14 through the oil guide column 13 and then seep out through the oil outlet 8, thereby lubricating the surface of the guide pad 5. During this process, the one-way valve assembly 19 in the oil guide pipe 16 is closed to ensure the oil outlet effect of the oil guide column 13. The guide pad 5 can prevent the guide slope 4 from scraping the bottom of the wire storage box 1. The shock absorber 6, together with the elastic drive mechanism 7, can buffer the wire storage box 1. At the same time, the lubricating oil can reduce the friction between the wire storage box 1 and the guide pad 5, thereby effectively reducing the wear of the positioning seat 3 on the wire storage box 1.

[0066] During the downward pressing process, the guide pad 5 can guide and correct the deviation of the wire storage box 1. When the shock absorber 6 abuts against the limit block 26, the lower edge 45 and the lower edge 46 are flush, so that the bottom edge of the wire storage box 1 can smoothly slide to the side of the positioning seat 3, and finally guide the wire storage box 1 to fall into the designated area of ​​the placement platform 2.

[0067] After the wire storage box 1 has fallen, the shock absorber 6 and guide pad 5 can be reset under the drive of the elastic drive mechanism 7, thereby restoring the oil storage buffer 11. During the restoration process, the silicone cross valve 14 closes and the elastic sealing plate 51 can open inward under negative pressure, thereby driving the second oil guide pipe 16 and the connecting oil pipe 18 to draw oil into the oil storage box 17, so that the oil storage buffer 11 is replenished with lubricating oil. After the oil replenishment is completed, the pressure inside and outside the one-way valve assembly 19 reaches equilibrium, thereby causing the elastic sealing plate 51 to close, so as to re-cut off the second oil guide pipe 16.

[0068] When the wire storage box 1 slides down the side wall of the positioning seat 3, the excess lubricating oil scraped off can fall into the oil receiving box 22, thereby keeping the placement table 2 clean and tidy.
