Description

Technical Field

[0001] The present invention relates to the technical field of water drill, and more particularly to a water drill feeding device and a feeding method. Background Art

[0002] Jewelry rhinestones, also known as crystal diamonds, simulated diamonds or zircon, are a type of imitation diamond material widely used in jewelry and decorations. They are usually made of materials such as glass, plastic or cubic zirconia (CZ), and look similar to natural diamonds, but at a lower cost.

[0003] In the prior art, the rhinestone feeding equipment includes an ejector pin, a corresponding clamp pin located above the ejector pin, and a material frame, wherein the ejector pin is located below the material frame. When working, the ejector pin pushes up to send the rhinestone in the material frame directly to the clamp pin, and then replaces the clamp pin with a new clamp pin after the ejector pin is removed. The ejector pin moves down and pushes up to send the rhinestone in the material frame to the new clamp pin, and the process is repeated. Since the rhinestone is directly pushed up by the ejector pin during feeding, the rhinestone falls on the ejector pin randomly, and it cannot be guaranteed that there will be a rhinestone on each ejector pin, which affects the processing efficiency. In addition, the position of the rhinestone on the ejector pin is also random and cannot be kept consistent, which affects the subsequent grinding accuracy.

[0004] In the prior art, the feeding device of the grinding and polishing machine with the publication number CN215201420U, compared with the above structure, has an additional horizontal driving cylinder for shaking the hopper and a material plate with material storage holes. During operation, the horizontal driving cylinder drives the hopper to move above the material plate, so that the rhinestones fall into the material storage holes and are supported by the embedded rhinestone thimbles, and then the thimbles are driven up by the transmission mechanism to connect with the fixture needle, and this is repeated. In this way, by shaking the hopper driven by the material plate with material storage holes and the horizontal driving cylinder, it can be effectively ensured that each thimble has a rhinestone, but the material holes are generally large, and after the rhinestones fall from the material mouth onto the thimbles, the consistency of the rhinestone position and the accuracy of the correct position cannot be guaranteed, which affects the subsequent grinding accuracy.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] refer to Figure 1-3A water drill feeding device comprises: a frame 1; a storage mechanism 2, which is installed on the top of the frame 1 and has a storage hopper 21 for storing water drills 5, and a blanking slot 221 is provided at the bottom of the storage hopper 21; a positioning transfer mechanism 3, which has a rotating shaft 31 installed on the frame 1 and located below the storage hopper 21, and a rotating driver 32 for driving the rotating shaft 31 to rotate, and a plurality of transfer strips 33 that can be rotated to correspond to the blanking slot 221 are installed around the outer wall of the rotating shaft 31 at intervals, and a plurality of receiving holes 331 for first positioning the water drill 5 are provided at one end of the transfer strip 33 away from the rotating shaft 31; a positioning feeding mechanism 4, which has a plurality of loading strips 41 located below the positioning transfer mechanism 3 and used for second positioning the water drill 5, and a loading drive assembly 42 that drives the plurality of loading strips 41 to move one by one to the right below the transfer strip 33 to receive the water drill 5 in the receiving hole 331 and then leave for loading.

[0044] It can be understood that the frame 1 is a supporting part 11 of the entire device. The storage hopper 21 is a component for storing the water drill 5, and can be, for example, a square frame structure or a circular frame structure with an opening at the top, but is not limited thereto. The blanking slot 221 is a component for centrally discharging the water drill 5, and can be, for example, a straight slot or a curved slot, but is not limited thereto. The material transfer strip 33 is a component installed on the rotating shaft 31 for extending the material receiving hole 331 to the blanking slot 221 and the loading strip 41, and can be, for example, a square strip structure or a long raised structure, but is not limited thereto. The material receiving hole 331 is a component for accommodating and positioning the water drill 5, and here, the material receiving hole 331 can be just a hole-shaped structure, or a hole-shaped structure combined with electromagnetic suction, a hole-shaped structure combined with air suction, etc., but is not limited thereto. The arrangement shape of the plurality of receiving holes 331 is adapted to the shape of the blanking slot 221. For example, if the blanking slot 221 is a straight slot, the plurality of receiving holes 331 are arranged in a straight line; if the blanking slot 221 is a curved slot, the plurality of receiving holes 331 are arranged in a curved line, etc. The rotary driver 32 may be a stepper motor or a servo motor, etc. The loading bar 41 is a component for receiving the diamond 5 in the receiving hole 331 and performing secondary positioning on the diamond 5. For example, it may be a long strip structure with a positioning hole 411 or a positioning slot 431, etc., but is not limited thereto. The loading drive assembly 42 is a component that drives the loading bar 41 to move to the loading area. For example, it may be a horizontal linear drive module that drives the loading bar 41 to move horizontally, or it may be a horizontal linear module that cooperates with a vertical linear module to realize the combined horizontal and vertical movement of the loading bar 41, etc., but is not limited thereto. Here, the horizontal linear module can be used to move the loading strip 41 unidirectionally or cyclically; it can also be located on both sides of the bottom of the rotating shaft 31 and perform a double-station operation with bidirectional movement.

[0045] With such a configuration, the rotating shaft 31 rotates to align the loading strip 41 with the blanking slot 221, and the diamonds 5 in the storage tank pass through the blanking slot 221 and enter the receiving hole 331 at the top of the loading strip 41 for the first positioning. The rotating shaft 31 rotates again to convert the transfer strip 33 with the diamonds 5 to face downward and correspond to the loading strip 41, and the diamonds 5 are placed on the loading strip 41 for the second positioning. While the rotating shaft 31 rotates, the other transfer strip 33 without diamonds 5 will be rotated to correspond to the blanking slot 221 for the first positioning of the diamonds 5. The loading drive assembly 42 will drive the loading strip 41 with diamonds 5 to move to the loading area, and move the loading strip 41 without diamonds 5 to the bottom of the rotating shaft 31. The rotating shaft 31 rotates again to convert the transfer strip 33 with diamonds 5 to correspond to the loading strip 41, and then the diamonds 5 are placed for the second positioning. By repeating this process, not only can the diamond drill 5 be positioned twice to improve the positioning accuracy, but the diamond drill 5 can also be changed to position the grinding surface of the diamond drill 5. At the same time, the rotation and rotation of multiple material transfer strips 33 on the rotating shaft 31, combined with the movement and rotation of multiple material transfer strips 41 by the material transfer drive assembly 42, can greatly improve the overall material transfer efficiency.

[0046] In some embodiments, the storage mechanism 2 further includes: a push hopper 22, which is horizontally guided and installed in the storage hopper 21 and is opened up and down; a push driver 23, which is installed on the storage hopper 21, and the output end is connected to the push hopper 22, thereby driving the push hopper 22 to sieve the water diamonds 5 inside and drop them into the blanking slot 221. It can be understood that the push hopper 22 is a component that repeatedly pushes the water diamonds 5, for example, it can be a square frame structure or a round frame structure, etc., and the horizontal guide installation of the push hopper 22 can adopt an axial hole guide structure or a slide rail guide structure, etc., but not limited to this. The push driver 23 is a component that drives the push hopper 22 to move horizontally, for example, it can be a cylinder, an electric push rod or a motor with a cam, etc., but not limited to this. In this way, when unloading, the push driver 23 repeatedly pushes the push hopper 22 to make the water diamonds 5 enter the blanking slot 221 and position them in the receiving hole 331, ensuring that each receiving hole 331 can receive the water diamonds 5. After the material is unloaded, the push drive 23 drives the push hopper 22 to move to one side of the material unloading slot 221. Since the diamonds 5 are all located in the push hopper 22, the diamonds 5 will no longer fall from the material unloading slot 221. Here, the distance between the bottom of the push hopper 22 and the bottom of the storage hopper 21 needs to be smaller than the height of the diamonds 5, thereby preventing the diamonds 5 from entering the gap between the push hopper 22 and the storage hopper 21.

[0047] In some embodiments, reference Figure 2-6, the storage hopper 21 is vertically guided and installed on the top of the frame 1; the storage mechanism 2 also includes a telescopic driver 24 that drives the storage hopper 21 to move up and down, thereby realizing that the transfer strip 33 is embedded in the blanking slot 221 and separated from the blanking slot 221. It can be understood that the vertical guide installation of the storage hopper 21 and the frame 1 can adopt an axial hole guide structure or a slide rail guide structure on both sides of the storage hopper 21, but is not limited to this. The telescopic driver 24 can be installed on the frame 1 to move the storage hopper 21 up and down, or it can be installed on the storage hopper 21 to drive itself and the storage hopper 21 to move up and down. Here, the telescopic driver 24 can be a cylinder or an electric push rod. In this way, the telescopic driver 24 drives the storage hopper 21 to move up, the rotating shaft 31 drives the receiving strip to rotate to the bottom of the blanking slot 221, and the telescopic driver 24 drives the storage hopper 21 to move down, so that the blanking slot 221 is sleeved on the transfer strip 33. At this time, the push hopper 22 is used to screen the water rhinestones 5, so that the water rhinestones 5 enter the receiving hole 331, and the push hopper 22 pushes the excess water rhinestones 5 to the side of the blanking slot 221. Then the telescopic driver 24 drives the storage hopper 21 to move upward, so that the blanking slot 221 is separated from the transfer strip 33, and the rotating shaft 31 drives the transfer strip 33 to be converted to correspond to the loading strip 41. During the rotation of the rotating shaft 31, another transfer strip 33 is rotated to the bottom of the blanking slot 221, and the telescopic driver 24 drives the storage hopper 21 to move downward and cover the transfer strip 33, and the operation is repeated. Here, after the material transfer strip 33 is embedded in the blanking groove 221, the top of the material transfer strip 33 is flush with or slightly lower than the bottom of the storage hopper 21. In this way, when excess diamonds 5 fall on the top of the material transfer strip 33, they will exceed the bottom surface of the storage hopper 21 and will eventually be pushed out by the material pushing frame. Therefore, except for the diamonds 5 in the receiving hole 331, no excess diamonds 5 will leak out of the blanking groove 221.

[0048] In some embodiments, reference Figure 6 , the rotating shaft 31 is provided with an inner cavity 311 in communication with the material receiving hole 331, and the inner cavity 311 is connected to a vacuum pump 312. It can be understood that the material receiving holes 331 on multiple material transfer strips 33 can be connected through an inner cavity 311, and a control valve 313 is installed at the connection between each material transfer strip 33 and the inner cavity 311; multiple inner cavities 311 can also be installed inside the rotating shaft 31, each inner cavity 311 is correspondingly connected to a material transfer strip 33, and a control valve 313 is installed at the connection between each inner cavity 311 and the vacuum pump 312. In this way, the material receiving hole 331 on each material transfer strip 33 can be controlled to suck and release the water drill 5.

[0049] In some embodiments, reference Figure 3 and Figure 6, the top of the feeding strip 41 is provided with a plurality of positioning holes 411 which are arranged one-to-one corresponding to the receiving hole 331 when the transfer strip 33 is facing downward, and the aperture of the positioning hole 411 is smaller than that of the receiving hole 331. It can be understood that the one-to-one correspondence means that the receiving hole 331 and the positioning hole 411 are opposite to each other up and down, and the diamond 5 in the receiving hole 331 can be positioned in the positioning hole 411 after falling. Here, it is preferred that when the receiving hole 331 is vertically facing downward, the central axis of the receiving hole 331 and the central axis of the positioning hole 411 are arranged on the same vertical line. The slightly larger aperture of the receiving hole 331 is to be able to preliminarily receive the diamond 5 in the pushing hopper 22, and to ensure the receiving rate of each receiving hole 331. If the aperture of the receiving hole 331 is directly set to be highly accurately matched with the diamond 5, it is difficult for the diamond 5 to enter the receiving hole 331. In this way, the diamond 5 can be initially positioned after falling into the receiving hole 331, and then enter the positioning hole 411 for high-precision positioning. The positioning accuracy of the diamond 5 can be greatly improved through two positionings, ensuring the subsequent grinding position accuracy and product quality.

[0050] In some embodiments, reference 2 and Figure 6-7 , one end of the diamond 5 is a flat bottom end 51, and the other end is a tapered end 52, the receiving hole 331 is fitted with the flat bottom end 51, and the positioning hole 411 is fitted with the tapered end 52. It can be understood that the thickness of the diamond 5 is smaller than its width, so that only when the diamond 5 is in a forward or reverse swing state, its height is the smallest, and it is higher than the forward or reverse swing height in a sideways state. However, when it is in a reverse swing, the tapered end 52 is facing downward, and it will fall sideways in a free state. Therefore, when designing, the distance from the bottom of the receiving hole 331 to the bottom of the storage hopper 21 is set to be equal to or slightly greater than the forward swing height of the diamond 5. In this way, only when the flat bottom end 51 of the diamond 5 is facing downward, the diamond 5 will not exceed the bottom surface of the storage hopper 21. When the diamond 5 falls sideways, the diamond 5 will exceed the top surface of the storage hopper 21, and the push hopper 22 will push the diamond 5 until the flat bottom end 51 of the diamond 5 faces downward. The side wall of the conical end 52 of the diamond 5 is a conical surface, and the side wall of the positioning hole 411 is set to a conical surface. If the side wall of the conical end 52 of the diamond 5 is a diamond-shaped conical surface, the side wall of the positioning hole 411 is set to a diamond-shaped conical surface. In this way, after the diamond 5 falls into the positioning hole 411, the consistency of the central axis of the diamond 5 and the central axis of the positioning hole 411 can be guaranteed, that is, the vertical state, to ensure the accuracy of the correct position of the diamond 5. In the overall process, the diamond 5 starts with a flat bottom facing downward, and then the flat bottom of the diamond 5 faces upward after the material connection strip and the loading strip 41 are connected. Finally, the flat bottom surface of the diamond 5 needs to be fixed by the clamp needle so that the conical end 52 faces outward, and the conical end 52 and the side wall are ground during the grinding process. Therefore, the device can also accurately fix the end face of the diamond 5 to ensure that the conical end 52 faces outward for grinding. Here, the clamp needle is a prior art and will not be described in detail here.

[0051] In some embodiments, reference Figure 8-10, the top of the feeding strip 41 is a plane or has a plurality of transverse grooves 412 corresponding to the receiving holes 331 and used to accommodate the diamonds 5; the positioning feeding mechanism 4 also includes: a positioning tooth plate 43, which is mounted on the frame 1 and located on one side of the positioning transfer mechanism 3, and the positioning tooth plate 43 is provided with a plurality of horizontally spaced positioning grooves 431 on the side close to the positioning transfer mechanism 3; a material ejector plate 44, which is arranged opposite to the positioning tooth plate 43, and is provided with a plurality of ejector pins 441 corresponding to the positioning grooves 431 on the side close to the positioning tooth plate 43; and an ejector driver 45, which is mounted on the frame 1 and has an output end connected to the ejector plate 44, thereby driving the ejector pins 441 on the ejector plate 44 to insert the diamonds 5 on the feeding strip 41 into the positioning grooves 431. It can be understood that when the outer wall of the diamond 5 is arc-shaped, such as a cylindrical diamond 5, a spherical diamond 5, etc., the positioning groove 431 is set to a smooth arc surface. When the outer wall of the diamond 5 is provided with a rhombus, the positioning groove 431 can also be provided in a shape that fits with the rhombus. Further, the feeding drive assembly 42 includes a horizontal driver 421 that drives the feeding strip 41 to move horizontally, and a longitudinal driver 422 that drives the feeding strip 41 to move longitudinally. The horizontal driver 421 and the longitudinal driver 422 can be a telescopic cylinder, a threaded screw drive, an electric push rod, etc., and the horizontal and vertical movement of the feeding strip 41 is achieved by combining these moving devices. In this way, after the diamond 5 falls on the feeding strip 41, the feeding drive assembly 42 drives the feeding strip 41 to move to the lower part between the positioning tooth plate 43 and the ejector plate 44, and then moves the feeding strip 41 upward so that the diamond 5 is located between the positioning tooth plate 43 and the ejector plate 44, and then drives the ejector plate 44 to move toward the positioning tooth plate 43 through the ejector driver 45, so that the ejector pin 441 pushes the diamond 5 to be stuck in the positioning groove 431, and the second positioning is completed.

[0052] In some embodiments, the frame 1 includes two support parts 11 arranged at intervals, and a fixed plate 12 and a bottom plate 13 are installed between the two support parts 11 at upper and lower intervals. The fixed plate 12 is used to install the storage mechanism 2 and has a hollow area 121 corresponding to the blanking slot 221 in the middle, and the bottom plate 13 is used to install the feeding strip 41 and the feeding drive assembly 42. It can be understood that the support part 11 is used to support the entire frame and install the rotating shaft 31. For example, it can be a plate structure or a structure composed of multiple connecting rods. The fixed plate 12 is a component connected to the storage hopper 21 for guiding. The function of the hollow area 121 is to cooperate with the water drill 5 to discharge the material, so the hollow area 121 can be partially hollowed out or completely hollowed out. A slide rail or the like can be installed on the bottom plate 13 to cooperate with the feeding strip 41 for horizontal movement.

[0053] A water drill, feeding device, the steps are as follows:

[0054] S1, putting the diamond 5 into the storage hopper 21, and the diamond 5 falls into the receiving hole 331 of the transfer bar 33 through the material dropping slot 221 for the first positioning;

[0055] S2, the rotary driver 32 drives the rotating shaft 31 to rotate, thereby driving the transfer strip 33 equipped with the rhinestone 5 to rotate to correspond to the loading strip 41 and put the rhinestone 5 on the loading strip 41 for the second positioning, and during the rotation of the rotating shaft 31, the other transfer strip 33 without the rhinestone 5 is rotated to correspond to the blanking slot 221;

[0056] S3, the loading strip 41 equipped with the rhinestones 5 is driven to move to the loading area by the loading drive assembly 42, and the other loading strip 41 not equipped with the rhinestones 5 is moved to the corresponding position of the transfer strip 33.

[0057] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
