Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automation technology, specifically relating to a numerical control transfer mechanism. Background Technology
[0002] There is a lightweight product that is easy to clamp and place stably. During the production process, it needs to be transferred in opposite directions, that is, first picked up from one side, then rotated 180° and fed to the opposite side. Currently, the commonly used transfer tool is an integrated robotic arm. However, if there are many production lines, using robotic arms for all of them would be relatively expensive. Therefore, a CNC transfer mechanism was designed to solve the above problems.
[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content
[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a CNC transfer mechanism.
[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a CNC transfer mechanism, including a mounting frame, a transfer unit disposed in the middle of the mounting frame, and a lifting and flipping storage unit disposed on both sides of the transfer unit, both storage units being disposed on the mounting frame; the transfer unit includes a crossbeam fixed to the mounting frame, and a transport handle disposed below the crossbeam that can reciprocate along its length direction, the transport handle being rotatable around the vertical direction; the storage unit includes a storage box with an opening on one side and a drive unit that drives the storage box to flip and move up and down, a clamping unit disposed at the opening of the storage box, and the transport handle being disposed below the lowest position of the storage box. In this solution, the transfer unit, through the cooperation of the two storage units, can pick up material from one side and transfer it to the other side via the transport handle for feeding, which is relatively low-cost compared to purchasing an integrated robotic arm for picking and feeding.
[0006] Furthermore, the drive unit includes two rotating bases respectively disposed on both sides of the storage bin. The lower end of the rotating base is rotatably connected to the outer wall of the storage bin, and the upper end of the rotating base is provided with a guide post. A lifting and fixing plate is disposed above the rotating base and is fixed on the mounting frame. The upper end of the guide post passes through the lifting and fixing plate. The outer side of the middle part of the rotating base is rotatably connected to the cylinder body of a tilting cylinder. The piston rod of the tilting cylinder is rotatably connected to one end of a lifting lug, and the other end of the lifting lug is fixedly connected to the storage bin. A ball screw jack is disposed on the lifting and fixing plate. The lower end of the ball screw jack passes through the lifting and fixing plate and is connected to the rotating base. A lifting motor is disposed on the mounting frame, and the ball screw jack is connected to the lifting motor through a combination of a synchronous chain and a sprocket. In this solution, the lifting motor is connected to the control system, and the rotation of the base is realized through the transmission of the synchronous chain and sprocket, thereby realizing the lifting of the storage box. The rotating base is kept stationary by the limit of the lifting fixed plate. The tilting cylinder is also connected to the control system. The extension and retraction of the tilting cylinder can make its body rotate around the rotating base, and rotate the storage box together to realize the tilting movement.
[0007] Furthermore, the rotating base has two guide columns, located on both sides of the ball screw jack, and each guide column is equipped with a linear bearing. In this design, the two guide columns make the operation more stable, and the linear bearings make the linear motion more accurate.
[0008] Furthermore, the clamping unit includes four clamping plates disposed along the four perimeters of the opening side of the storage bin. Each clamping plate is movable back and forth toward the center of the opening side of the storage bin. Each clamping plate is connected to a clamping cylinder via a transmission, and each clamping cylinder is fixed to the storage bin. In this solution, the clamping unit is connected to a control system, which controls the movement of the clamping cylinders. The movement of the four clamping plates enables the clamping and unloading of the product. The product can have corresponding clamping positions. This mechanism is only applicable to products that can be clamped. The shape, weight, and other influencing factors of the product are not considered here and will not be elaborated further.
[0009] Furthermore, a material transfer guide rail is provided on the crossbeam, and a movable frame is provided below the crossbeam. The movable frame is movably mounted on the material transfer guide rail. A material transfer motor is provided on the crossbeam, and the movable frame is connected to the material transfer motor via a synchronous belt. The handling arm is connected to a worm gear rotary reducer via a handling bracket. The worm gear rotary reducer is fixed to the lower end of the movable frame and drives the handling arm to rotate through a driving component. In this design, the worm gear rotary reducer is connected to the control system. The worm gear rotary reducer is mainly used to transmit and convert the power of the driving component into low-speed, high-torque rotary motion.
[0010] Furthermore, the transport handle consists of a first moving rod, a second moving rod, and a third moving rod. The first and second moving rods are arranged in parallel, and the same side ends of the first and second moving rods are respectively fixed to the two ends of the third moving rod. The middle part of the third moving rod is fixed to the transport bracket. In this solution, the product can be placed stably on the transport handle, and the lower end face of the product can have a corresponding locking position. This mechanism is only applicable to products that can be placed stably; the shape, weight, and other influencing factors of the product are not considered here and will not be elaborated further.
[0011] Furthermore, the transport bracket is L-shaped. In this design, the L-shaped transport bracket facilitates handling and connection with the worm gear rotary reducer.
[0012] Furthermore, the mounting frame comprises a first gantry frame, a second gantry frame, a first mounting beam, and a second mounting beam. The first and second gantry frames are arranged in parallel, and the first and second mounting beams are also arranged in parallel and fixed between the first and second gantry frames. The crossbeam of the material transfer unit is arranged parallel to the first and second mounting beams and located between them. In this design, the mounting beams and gantry frames are arranged vertically. The first and second mounting beams are shaped like a "Π", and their lower ends are fixedly connected to the upper ends of the gantry frames. The fixing methods include, but are not limited to, welding and bolt connections.
[0013] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:
[0014] The CNC transfer mechanism designed in this utility model, through the cooperation of the transfer unit and two storage units, realizes the process of picking up the product from one side, flipping it 180° and then feeding it to the other side. Compared with purchasing an integrated robotic arm to realize the picking and feeding, the cost is relatively low, the practicality is strong, and it is suitable for promotion.

Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0032] Example:
[0033] See appendix Figure 1As shown, this embodiment provides a CNC transfer mechanism, including a mounting frame 1. A transfer unit 2 is arranged in the middle of the mounting frame 1, and a lifting and flipping storage unit 3 is provided on both sides of the transfer unit 2. Both storage units 3 are mounted on the mounting frame 1; see attached figure. Figure 6 As shown, the material transfer unit 2 includes a crossbeam 21 fixed on the mounting frame 1. Below the crossbeam 21 is a transfer handle 22 that can reciprocate along its length. The transfer handle 22 is rotatable in the vertical direction and can reciprocate to pick up materials from both sides where the two storage units 3 are located. (See attached diagram) Figure 2 As shown, the storage unit 3 includes a storage box 31 with an opening on one side and a drive unit 4 that drives the storage box 31 to flip and move up and down. A material clamping unit is provided at the opening of the storage box 31, and the handling hand 22 is set below the lowest position of the storage box 31.
[0034] The initial state of the two side storage bins 31 can be one with its opening facing downwards (for retrieving or discharging materials), see Appendix. Figure 3 As shown, one opening faces outwards (for receiving or feeding materials), see attached document. Figure 2 As shown. The storage bin 31 with its opening facing outwards retrieves material from the outside via the clamping unit. At this point, the product position is set to 0°. Then, the storage bin 31, carrying the product, flips downwards, rotating the product 90°. The transport handle 22 of the transfer unit 2 moves along the length of the crossbeam 21 to one side of the storage bin 31 (inside the storage unit 3). The transport handle 22 rotates to a position below the currently downward-facing storage bin 31. The storage bin 31 descends and releases the product via the clamping unit, placing the product on the transport handle 22. The storage bin 31, having completed feeding, rises and flips back to its initial outward-facing state, retrieving material from the outside. At this time, the storage bin 31 on the other side is empty and downward-facing (it must also be reset to the downward-facing state after feeding). The storage bin 31 descends, retrieves the product from the transport handle 22 via the closing clamping unit, flips again, and repeats the outward feeding process, rotating the product 180°. The material transfer unit 2, through the cooperation of two material storage units 3, can pick up materials from one side, flip them 180°, and then feed them to the other side. Compared with purchasing an integrated robotic arm for picking and feeding, the cost is relatively low.
[0035] The storage bin 31 can provide some dust protection for the products during the product transfer and waiting process.
[0036] See appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5As shown, the drive unit 4 includes two rotating bases 41 respectively disposed on both sides of the storage bin 31 (on both sides of the rotating center axis of the storage bin 31). The lower end of the rotating base 41 is rotatably connected to the outer wall of the storage bin 31. The upper end of the rotating base 41 is provided with a guide post 42. A lifting fixing plate 43 is provided above the rotating base 41. The lifting fixing plate 43 is fixed on the mounting frame 1. The upper end of the guide post 42 passes through the lifting fixing plate 43. The outer side of the middle part of the rotating base 41 is rotatably connected to the cylinder body of a tilting cylinder 44. The piston rod of the tilting cylinder 44 is rotatably connected to one end of a lifting lug 45. The other end of the lifting lug 45 is fixedly connected to the storage bin 31. A ball screw jack 46 is provided on the lifting fixing plate 43. The lower end of the ball screw jack 46 passes through the lifting fixing plate 43 and is connected to the rotating base 41. A lifting motor 47 is provided on the mounting frame 1. The ball screw jack 46 is connected to the lifting motor 47 through a combination of a synchronous chain 48 and a sprocket 49.
[0037] The lifting motor 47 is connected to the control system. Through the transmission of the synchronous chain 48 and the sprocket 49, the rotating base 41 moves up and down, thereby realizing the lifting and lowering of the storage box 31. The rotating base 41 is kept stationary by the limit of the lifting fixing plate 43. The tilting cylinder 44 is also connected to the control system. The extension and retraction of the tilting cylinder 44 can make its body rotate around the rotating base 41, and rotate the storage box 31 together to realize the tilting movement.
[0038] See appendix Figure 5 As shown, the rotating base 41 has two guide columns 42, located on both sides of the ball screw jack 46, and each guide column 42 is equipped with a linear bearing. The design of two guide columns 42 makes the operation more stable, and the design of linear bearings makes the linear motion more accurate.
[0039] See appendix Figure 2 As shown, the material clamping unit includes four clamping plates 32 disposed around the four perimeters of the opening side of the storage box 31. Each clamping plate 32 is moved back and forth toward the center of the opening side of the storage box 31. Each clamping plate 32 is connected to a clamping cylinder 33, and each clamping cylinder 33 is fixed to the storage box 31. The material clamping unit is connected to the control system, which controls the movement of the clamping cylinders 33. The movement of the four clamping plates 32 realizes the clamping and unloading of products. There can be corresponding clamping positions on the products. This mechanism is only applicable to products that can be clamped. The shape, weight, and other influencing factors of the products are not considered here and will not be elaborated further.
[0040] See appendix Figure 6As shown, a material transfer guide rail 23 is installed on the crossbeam 21, and a movable frame 24 is installed below the crossbeam 21. The movable frame 24 is movably mounted on the material transfer guide rail 23. A material transfer motor 25 is installed on the crossbeam 21, and the movable frame 24 is connected to the material transfer motor 25 via a synchronous belt 26. A handling hand 22 is connected to a worm gear rotary reducer 28 via a handling bracket 27. The worm gear rotary reducer 28 is fixed to the lower end of the movable frame 24 and drives the handling hand 22 to rotate through a drive component. The worm gear rotary reducer 28 is connected to the control system. The model of the worm gear rotary reducer 28 can be SE9A-61-25H-R. The worm gear rotary reducer 28 is mainly used to transmit and convert the power of the drive component into low-speed, high-torque rotary motion. It also has a self-locking function, which can automatically lock the position when the power is off or the drive stops to prevent the load from reversing (no additional braking device is required).
[0041] See appendix Figure 6 As shown, the transport handle 22 consists of a first moving rod 221, a second moving rod 222, and a third moving rod 223. The first moving rod 221 and the second moving rod 222 are arranged in parallel. The same side end of the first moving rod 221 and the second moving rod 222 are respectively fixed to the two ends of the third moving rod 223. The middle part of the third moving rod 223 is fixed to the transport bracket 27. The product can be placed stably on the transport handle 22. The lower end face of the product can have a corresponding locking position when placed. This mechanism is only suitable for products that can be placed stably. The shape, weight, and other influencing factors of the product are not considered here and will not be elaborated on. The transport bracket 27 is L-shaped. The L-shaped structure of the transport bracket 27 makes it easier to connect the transport handle 22 and the worm gear rotary reducer 28.
[0042] See appendix Figure 7 As shown, the mounting frame 1 consists of a first gantry frame 11, a second gantry frame 12, a first mounting beam 13, and a second mounting beam 14. The first gantry frame 11 and the second gantry frame 12 are arranged in parallel, and the first mounting beam 13 and the second mounting beam 14 are arranged in parallel and fixed between the first gantry frame 11 and the second gantry frame 12. The crossbeam 21 of the material transfer unit 2 is arranged parallel to the first mounting beam 13 and the second mounting beam 14 and is located between them. The mounting beams and the gantry frames are arranged perpendicularly. The first mounting beam 13 and the second mounting beam 14 are in the shape of a "Π", and their lower ends are fixedly connected to the upper ends of the gantry frames. The fixing methods include, but are not limited to, welding and bolt connection.
[0043] In this embodiment, the control system is a numerical control system with a built-in PLC, which triggers the solenoid valve through ladder diagrams or G-code (such as M-code). For example, for pneumatic components such as cylinders, the numerical control system outputs electrical signals (such as 24V digital signals or analog signals), which are converted into pneumatic actions by the solenoid valve to control the extension and retraction of the cylinder. The numerical control system controls the solenoid valve through digital input / output (DI / DO) or bus (such as PROFIBUS, EtherCAT).
[0044] The CNC transfer mechanism designed in this utility model, through the cooperation of the transfer unit and two storage units, realizes the process of picking up the product from one side, flipping it 180° and then feeding it to the other side. Compared with purchasing an integrated robotic arm to realize the picking and feeding, the cost is relatively low, the practicality is strong, and it is suitable for promotion.
[0045] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
