Description

Technical Field

[0001] This invention relates to the field of warehouse automation technology, and more specifically, to a wire saw mold library. Background Technology

[0002] Diamond wire saw molds are the core components in the production of diamond wire saws. They are mostly cylindrical disc-shaped structures with uniform specifications. The end face of the mold is usually engraved with a QR code to realize identification and information traceability. The accuracy of the inner hole size of the mold directly determines the quality of the finished diamond wire saw.

[0003] In the large-scale production of diamond wire saws, centralized warehousing and intelligent inbound / outbound management of a large number of wire saw dies are required. Current technologies often use stacked bins or layered shelving for warehousing, which has the following drawbacks: 1. The reliance on manual sorting or traditional conveyor belt transfer for mold entry and exit can easily lead to problems such as mold collisions and disordered stacking, resulting in wear and tear on the mold's QR code and deformation of the inner hole, which affects subsequent identification and use; 2. Some warehousing solutions use vertical tube storage molds. When the molds are placed from the top of the tube, they fall freely. Due to the impact of gravity, the 304 stainless steel molds will collide with the bottom of the tube or the lower molds, causing damage to the mold end face, blurring of the QR code, and reducing the service life and recognition accuracy of the molds. 3. Traditional storage devices lack flexible slow-descent adjustment mechanisms. If a slow-descent component is configured separately for each storage cylinder, it will result in high equipment costs and complex structures, which is not conducive to large-scale deployment. 4. The lack of an efficient identification and sorting mechanism during the mold feeding process makes it impossible to quickly remove defective products without QR codes, affecting the efficiency of inbound and outbound operations.

[0004] Therefore, developing a wire saw mold storage system that enables stable mold storage, intelligent identification and sorting, and efficient inbound and outbound operations has become a key requirement for solving current industry pain points. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wire saw mold library, which realizes intelligent and refined warehouse management of wire saw molds.

[0006] To solve the above-mentioned technical problems, the purpose of this invention is achieved as follows: The present invention relates to a wire saw mold library, including a frame, on which a mold feeding device, a mold unloading device and a mold storage bin are provided. The mold storage bin includes several vertically extending non-metallic tubes. Two vertically extending and oppositely arranged permanent magnets are provided on the inner or outer side of the non-metallic tubes. The magnetic poles of the permanent magnets can be opposite polarity or same polarity.

[0007] The present invention is further configured such that at least one of the non-metallic tubes is provided with two permanent magnets.

[0008] The invention is further configured to include a transfer mechanism for controlling the position switching of two relatively arranged permanent magnets between different non-metallic tubes. The transfer mechanism includes a first pneumatic gripper and a first gantry robot for controlling the first pneumatic gripper to move freely in three-dimensional space. Each permanent magnet is connected to one gripper of the first pneumatic gripper.

[0009] The present invention is further configured such that each of the non-metallic tubes is provided with two permanent magnets.

[0010] The present invention is further configured such that: the permanent magnet is disposed on the outside of the non-metallic tube; and the magnetic poles of the permanent magnet are arranged in a manner of opposite polarity.

[0011] The present invention is further configured such that: the mold feeding device includes a low-level feeding conveyor belt near the bottom of the non-metallic tube and a high-level feeding conveyor belt near the top of the non-metallic tube, and a slope feeding conveyor belt is provided as a transition between the high-level feeding conveyor belt and the low-level feeding conveyor belt; Above the low-position feeding conveyor belt is a first conveying rail extending along the conveying direction of the conveyor belt. One end of the first conveying rail is flared and the other end is provided with a first baffle plate. The first baffle plate is provided with a first linear reciprocating motion mechanism that controls horizontal movement. The movement direction of the first baffle plate is perpendicular to the extension direction of the first conveying rail. Above the low-position feeding conveyor belt is also a second pneumatic gripper and a rotary cylinder that controls the second pneumatic gripper to rotate 180°. An industrial camera is mounted above the second pneumatic gripper. Above the low-position feeding conveyor belt is an anti-stacking railing near the feeding end. Above the high-level feeding conveyor belt, a second conveying rail is erected that extends along the conveying direction of the conveyor belt. One end of the second conveying rail is flared and the other end is equipped with a second baffle plate. The mold feeding device also includes a third pneumatic gripper located above the high-level feeding conveyor belt, and a second gantry robot that can move freely in three-dimensional space is mounted on the third pneumatic gripper.

[0012] The present invention is further configured such that: a third baffle plate is mounted above the low-position feeding conveyor belt near the unloading end, and a second linear reciprocating motion mechanism for controlling lifting and lowering is provided on the third baffle plate; and a defective product storage frame is connected to the unloading end of the low-position feeding conveyor belt. When the third barrier plate is in the descending position, it can be used as a guide plate to guide the material to the conveyor belt on the slope.

[0013] The present invention is further configured such that: both the first linear reciprocating motion mechanism and the second linear reciprocating motion mechanism are push rod cylinders.

[0014] The present invention is further configured such that: the mold unloading device includes an unloading conveyor belt located below all non-metallic tubes, all non-metallic tubes are arranged in a rectangular array, each row of non-metallic tubes is arranged at equal intervals along the conveying direction of the unloading conveyor belt, and each non-metallic tube is provided with a discharge component at its bottom. The discharge assembly includes a discharge pipe extending radially along the non-metallic tube, with an opening on the side of the discharge pipe communicating with the bottom of the non-metallic tube, a discharge column slidably connected inside the discharge pipe, a discharge push plate at one end of the discharge column, and a mold unit storage compartment that runs vertically through the discharge column. The mold unloading device further includes a linear module, a push rod cylinder, and an actuator block. The linear module is arranged along the conveying direction of the unloading conveyor belt. The push rod cylinder is located on the slide table of the linear module. The actuator block is located on the telescopic rod of the push rod cylinder. The telescopic direction of the push rod cylinder is perpendicular to the conveying direction of the unloading conveyor belt. The actuator block has a clearance groove that runs through the front and back along the conveying direction of the unloading conveyor belt and is open to the outside at its lower end. One of the discharge push plates is located in the clearance groove.

[0015] The present invention is further configured such that the permanent magnet is a neodymium iron boron permanent magnet.

[0016] In summary, the present invention has the following beneficial effects: 1. Utilizing Lenz's law, neodymium iron boron permanent magnets are arranged opposite each other on the outside of the non-metallic tube. This causes the falling 304 stainless steel mold to generate eddy current damping force by cutting through the transverse magnetic field, transforming free fall into a smooth, gradual descent. This completely avoids end-face wear, QR code blurring, and internal hole deformation caused by gravitational impact, extending the mold's service life. Two permanent magnet configuration options are also provided, balancing flexibility and stability to adapt to different warehousing needs.

[0017] 2. The feeding device is equipped with an industrial camera, pneumatic grippers and rotary cylinders to perform secondary photo recognition on both ends of the mold. With the help of the baffle plate and linear reciprocating motion mechanism, it can accurately screen out defective products without QR codes and guide them to the defective product storage box, effectively improving the pass rate of the molds entering the warehouse. The design of anti-stack railings and conveyor rails ensures orderly conveying of molds and avoids blockage and jamming.

[0018] 3. By relying on the linkage between the gantry robot and the pneumatic gripper, the automated grasping, transfer and storage of molds are realized; the material discharge component completes the molds out of the warehouse one by one through the cooperation of linear modules, push rod cylinders and execution blocks. The whole process does not require manual intervention, which greatly improves the efficiency of warehouse management and reduces the intensity of manual labor.

[0019] 4. Non-metallic tubes are arranged in a rectangular array to make full use of vertical space and increase storage density; the feeding device adopts a three-stage conveyor belt transition structure, and the straight module of the unloading device can serve multiple rows of tubes. The overall structure is compact and easy to connect seamlessly with diamond wire saw production lines. Attached Figure Description

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions of the present invention, preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are merely for further illustrating the features and advantages of the present invention, and not for limiting the scope of the patent claims of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0023] Example 1 See Figures 1 to 10 As shown, the wire saw mold library involved in this embodiment includes a frame 1. The frame is equipped with a mold feeding device, a mold unloading device and a mold storage bin. The mold storage bin includes several non-metallic tubes 2 extending vertically. Two permanent magnets 3 extending vertically and arranged opposite to each other are provided on the outer side of the non-metallic tubes 2.

[0024] Furthermore, one of the non-metallic tubes 2 is equipped with two permanent magnets 3, and the system also includes a transfer mechanism that controls the relative arrangement of the two permanent magnets 3 to switch positions between different non-metallic tubes 2. The transfer mechanism includes a first pneumatic gripper 4 and a first gantry robot 5 that controls the first pneumatic gripper to move freely in three-dimensional space.

Above the high-level feeding conveyor belt 7, a second conveying rail 16 extending along the conveying direction of the conveyor belt is erected. One end of the second conveying rail 16 is flared and the other end is provided with a second baffle plate 17. The mold feeding device also includes a third pneumatic gripper 18 located above the high-level feeding conveyor belt 7, and a second gantry robot 19 that is controlled to move freely in three-dimensional space is mounted on the third pneumatic gripper 18.

[0026] Furthermore, a third baffle plate 20 is mounted above the low-position feeding conveyor belt 6 near the unloading end. The third baffle plate 20 is equipped with a second linear reciprocating motion mechanism (not shown) for controlling lifting and lowering. The unloading end of the low-position feeding conveyor belt 6 is connected to a defective product storage frame 21. When the third barrier plate 20 (which is inclined relative to the conveying direction so as to guide the material to the incline conveyor belt) is in a descending position, it can be used as a guide plate and guide the material to the incline conveyor belt 8.

[0027] Furthermore, both the first linear reciprocating motion mechanism 11 and the second linear reciprocating motion mechanism are push rod cylinders.

[0028] Furthermore, the mold unloading device includes an unloading conveyor belt 22 located below all the non-metallic tubes 2. All the non-metallic tubes 2 are arranged in a rectangular array. Each row of the non-metallic tubes 2 is arranged at equal intervals along the conveying direction of the unloading conveyor belt 3. Each non-metallic tube 2 is provided with a discharge component at its bottom. The discharge assembly includes a discharge pipe 23 extending radially along the non-metallic cylindrical tube 2. The side of the discharge pipe 23 has an opening communicating with the bottom of the non-metallic cylindrical tube 2. A discharge column 24 is slidably connected inside the discharge pipe 23. One end of the discharge column 24 is provided with a discharge push plate 25. A mold unit storage compartment 26 that runs vertically through the discharge column 24 is provided on the discharge column 24. The mold unloading device further includes a linear module 27, a push rod cylinder 28, and an execution block 29. The linear module 27 is arranged along the conveying direction of the unloading conveyor belt 22. The push rod cylinder 28 is mounted on the slide table of the linear module 27. The execution block 29 is mounted on the telescopic rod of the push rod cylinder 28. The telescopic direction of the push rod cylinder 28 is perpendicular to the conveying direction of the unloading conveyor belt 22. The execution block 29 has a clearance groove 30 that runs through the front and back along the conveying direction of the unloading conveyor belt 22 and is connected to the outside at its lower end. One of the discharge push plates 25 is located in the clearance groove 30.

[0029] Material loading and warehousing process: 1. Scattered wire saw dies are conveyed by a low-level feeding conveyor belt, and anti-stacking railings block the stacked dies, so that the dies are arranged in a single layer and enter the first conveyor rail. 2. The industrial camera takes a picture of one end face of the mold for the first time. If the QR code is recognized, the first push rod cylinder drives the first barrier plate to retract. The mold moves along the first conveyor rail to the third barrier plate. The second push rod cylinder drives the third barrier plate to descend. The mold is guided by the third barrier plate to the slope conveyor belt and then conveyed to the second conveyor rail of the high-level conveyor belt. 3. The second gantry robot drives the third pneumatic gripper to grab the qualified mold on the high-level feeding conveyor belt, move it to the top inlet of the target non-metallic tube and release it; at the same time, the first gantry robot drives the first pneumatic gripper to move two permanent magnets to the outside of the non-metallic tube and fix them. As the mold falls along the tube, the transverse magnetic field formed by cutting the permanent magnets generates eddy current damping force, and the mold falls smoothly and slowly to the bottom of the tube, completing the storage. 4. If no QR code is found during the first identification, the rotary cylinder drives the second pneumatic gripper to grab the mold and rotate it 180°. The industrial camera performs a second identification. If no QR code is found, the product is considered defective. The third barrier plate remains raised, and the defective products are diverted to the defective product storage box.

[0030] Outbound process: 1. When molds need to be released from the warehouse, the linear module drives the push rod cylinder to move to the discharge assembly corresponding to the target non-metallic tube; 2. The mold at the bottom of the non-metallic tube falls into the mold unit storage bin of the discharge column; 3. The push rod cylinder drives the actuator block to extend. The actuator block drives the discharge push plate to move through the clearance groove, pushing the discharge column out along the discharge pipe until the mold unit storage bin moves above the discharge conveyor belt. The mold falls onto the discharge conveyor belt and is transported to the next process. 4. The push rod cylinder drives the actuator block to reset, and the discharge column returns to its initial position, waiting for the next discharge.

[0031] Example 2 See Figures 1 to 10 As shown, the wire saw mold library involved in this embodiment includes a frame 1. The frame is equipped with a mold feeding device, a mold unloading device and a mold storage bin. The mold storage bin includes several non-metallic tubes 2 extending vertically.

Above the low-position feeding conveyor belt 6, a first conveying rail 9 extending along the conveying direction of the conveyor belt is erected. One end of the first conveying rail 9 is flared and the other end is provided with a first baffle plate 10. The first baffle plate 10 is provided with a first linear reciprocating motion mechanism 11 that controls horizontal movement. The movement direction of the first baffle plate 10 is perpendicular to the extension direction of the first conveying rail 9. Above the low-position feeding conveyor belt 6, a second pneumatic gripper 12 and a rotary cylinder 13 that controls the second pneumatic gripper 12 to rotate 180° are also provided. An industrial camera 14 is erected above the second pneumatic gripper 12. Above the low-position feeding conveyor belt 6, an anti-stacking railing 15 is erected near the feeding end. Above the high-level feeding conveyor belt 7, a second conveying rail 16 extending along the conveying direction of the conveyor belt is erected.

The mold feeding device also includes a third pneumatic gripper 18 located above the high-level feeding conveyor belt 7, and a second gantry robot 19 that is controlled to move freely in three-dimensional space is mounted on the third pneumatic gripper 18.

[0034] Furthermore, a third baffle plate 20 is mounted above the low-position feeding conveyor belt 6 near the unloading end. The third baffle plate 20 is equipped with a second linear reciprocating motion mechanism (not shown) for controlling lifting and lowering. The unloading end of the low-position feeding conveyor belt 6 is connected to a defective product storage frame 21. When the third barrier plate 20 (which is inclined relative to the conveying direction so as to guide the material to the incline conveyor belt) is in a descending position, it can be used as a guide plate and guide the material to the incline conveyor belt 8.

[0035] Furthermore, both the first linear reciprocating motion mechanism 11 and the second linear reciprocating motion mechanism are push rod cylinders.

[0036] Furthermore, the mold unloading device includes an unloading conveyor belt 22 located below all the non-metallic tubes 2. All the non-metallic tubes 2 are arranged in a rectangular array. Each row of the non-metallic tubes 2 is arranged at equal intervals along the conveying direction of the unloading conveyor belt 3. Each non-metallic tube 2 is provided with a discharge component at its bottom. The discharge assembly includes a discharge pipe 23 extending radially along the non-metallic cylindrical tube 2. The side of the discharge pipe 23 has an opening communicating with the bottom of the non-metallic cylindrical tube 2. A discharge column 24 is slidably connected inside the discharge pipe 23. One end of the discharge column 24 is provided with a discharge push plate 25. A mold unit storage compartment 26 that runs vertically through the discharge column 24 is provided on the discharge column 24. The mold unloading device further includes a linear module 27, a push rod cylinder 28, and an execution block 29. The linear module 27 is arranged along the conveying direction of the unloading conveyor belt 22. The push rod cylinder 28 is mounted on the slide table of the linear module 27.

One of the discharge push plates 25 is located in the clearance groove 30.

[0037] The only difference between the material loading and warehousing process in this embodiment and that in embodiment 1 is that after the qualified mold is transferred to the top inlet of any non-metallic tube by the second gantry robot and the third pneumatic gripper and released, there is no need to deploy permanent magnets through the transfer mechanism. Instead, the mold can be directly lowered to the bottom of the tube by using the permanent magnets preset in the tube to generate a slow-descent damping force.

[0038] The outbound process in this embodiment is exactly the same as that in Embodiment 1, and will not be repeated here.

[0039] The wire saw mold library involved in this invention utilizes Lenz's law. By arranging neodymium iron boron permanent magnets on the outer side of a non-metallic tube, the falling 304 stainless steel mold generates eddy current damping force in the transverse magnetic field of the cutting process. This transforms the free fall into a smooth and gradual descent, completely avoiding end face wear, QR code blurring, and inner hole deformation caused by gravity impact, thus extending the mold's service life. Two permanent magnet configurations are offered, balancing flexibility and stability to suit different warehousing needs. The loading device is equipped with an industrial camera, pneumatic grippers, and rotary cylinders to perform secondary image recognition on both ends of the mold. Combined with baffles and a linear reciprocating motion mechanism, it can accurately screen out defective products without QR codes and guide them to the defective product storage box, effectively improving the pass rate of incoming molds. The design of anti-stacking rails and conveyor rails ensures orderly mold transportation and avoids blockage and jamming. Relying on the linkage of gantry robots and pneumatic grippers, the molds are automatically grasped, transferred, and stored. The unloading component completes the unloading of molds one by one through the cooperation of linear modules, push rod cylinders, and actuators. The entire process requires no manual intervention, greatly improving warehousing management efficiency and reducing manual labor intensity. In addition, non-metallic tubes are arranged in a rectangular array to make full use of vertical space and increase storage density. The loading device adopts a three-stage conveyor belt transition structure, and the linear module of the unloading device can serve multiple rows of tubes. The overall structure is compact and easy to seamlessly connect with diamond wire saw production lines. The overall function is complete and highly practical.
