Description

[0001] This application is a divisional application. The original application has the application number CN202311526173.2 and the application date is November 14, 2023. The subject matter of the invention is an efficient automatic water drill processing device. Technical Field

[0002] This application relates to the field of water drill processing and production, specifically to a high-efficiency automatic water drill processing device. Background Technology

[0003] Rhinestones, also known as crystal diamonds or rhinestones, are primarily made of crystal glass. They are jewelry accessories obtained by cutting artificial crystal glass into diamond facets. This material is popular because it is relatively inexpensive and has a dazzling diamond-like visual effect. It is widely used in low- to mid-range jewelry designs, hence rhinestones are mainly produced in batches.

[0004] Authorized patent CN104551915B discloses a fully automatic water drill grinding and polishing machine. It discloses a first grinding and polishing production line and a second grinding and polishing production line arranged opposite each other. The two production lines are connected by a rotating device on both sides, and both powder application stations are located at the beginning of the production lines. During the water drill processing, the flow of water drills in either production line is driven by a common drive device, while the needle bar (referred to as a clamp in the patent) flows sequentially between multiple stations to complete the grinding and polishing process. Although the common time for the needle bar to flow is the same, the time spent in different processes varies due to differences in operation and quality requirements. This results in differences in the dwell time of the needle bar at different stations. To ensure the normal operation of the entire production line, only the station with the longest dwell time can be used as the benchmark for the entire production line's production cycle. This leads to a longer processing time for a single water drill due to the bottleneck process, thus restricting the production efficiency and output of water drills. In addition, the grinding and polishing processes have time requirements for water rhinestone processing, especially the polishing process. If the grinding or polishing time is insufficient, it will directly affect the quality of the water rhinestone.

[0005] It is worth noting that for fully automated water drill production lines, since the entire production line is in a non-stop production state, the production cycle time (the processing time of the longest processing station in a single operation) means money. The longer the production cycle time, the lower the water drill processing efficiency and the lower the output. Conversely, the longer the production cycle time, the higher the water drill processing efficiency and the higher the output. Summary of the Invention

[0006] This application addresses the technical problem of low production efficiency and difficulty in balancing production efficiency and output quality in water rhinestone production lines with a dual-line circulating processing structure due to excessively long production cycles. It provides a high-efficiency automatic water rhinestone processing device, which has advantages such as high processing efficiency, sufficient output, and controllable yield.

[0007] This application provides a high-efficiency automatic water drill processing device, configured with a dual-line circulating processing structure, including a turntable, adhesive application, feeding, grinding, polishing, high-frequency heating, and unloading station, comprising:

[0008] The feeding station is set before the turntable station. After the pin pack completes the bead clamping at the feeding station, it enters the turntable station through the drive mechanism.

[0009] The rotary table position includes rotation operation and slewing operation; the rotation operation is that after the needle row enters the rotary table position, its turntable rotates 180°, driving the needle row from the end of one operating line to the beginning of another operating line; the slewing operation is that after the needle row that has entered the beginning of the operating line is driven by the drive structure of that operating line to enter the grinding process, its turntable rotates 180° to return to its original position, waiting for the next needle row to enter the rotary table position.

[0010] The rinsing process is integrated into the rotary table position, including a water outlet structure. The water outlet of the water outlet structure is located at the beginning of another rotary line, before entering the grinding process.

[0011] Specifically, one of the concepts in this application is to utilize the various processing and coordination structures of existing water drill production lines, and by optimizing the process positions and machine layout, eliminate bottleneck processes in the automatic processing equipment, reduce the production cycle time, and improve water drill processing efficiency, thereby achieving the goal of increasing water drill output.

[0012] First, this application separates the adhesive application process from the rotary table station, allowing the rotary table station to perform only rotational or slewing operations without additional adhesive application. This reduces the operational complexity of the rotary table station, ensuring its station time is only related to basic needle drive and slewing operations. This balances the overall production line's cycle time, reducing cycle time and improving production efficiency. Simultaneously, this application integrates the rinsing process, which does not require station time, into the rotary table station, filling the station gap left by the adhesive application separation. This eliminates the need for additional stations in the dual-line cycle processing structure, preventing unreasonable cost increases.

[0013] Furthermore, any processing line is arranged in the following order: adhesive gluing station, feeding station, turntable station, coarse grinding station, fine grinding station, first polishing station, second polishing station, high-frequency heating station, and unloading station; the unloading station of one processing line is connected to the adhesive gluing station of another processing line to form a double-line cycle.

[0014] Specifically, this application belongs to a dual-line circulating processing structure. When the machine position meets the process requirements, the two processing lines are connected end to end to achieve a closed processing cycle, thereby improving the space utilization rate of the efficient water drill automatic processing device provided in this application.

[0015] Furthermore, the installation position of the rotary table is moved away from the rough grinding machine position, and the length of the needle plate is extended based on the original size of the needle plate to reach the maximum allowable length for processing at the rough grinding machine position.

[0016] Specifically, another concept of this application lies in adjusting the production line structure so that the gluing process is no longer constrained by the turntable position. Therefore, when the dwell time at the turntable position only includes the rotation or return operation time plus the needle drive time, the drive time of the needle array can be adjusted. By lengthening the needle array, the distance the needle array moves is balanced, and the capacity of a single bead blank processing cycle is increased.

[0017] It is worth noting that the output of water drills is related not only to the production cycle time but also to the number of water drills clamped at one time. The more water drills the pin bar can hold at one time, the higher the output. Therefore, based on the adjustment and optimization of the structure of the automatic water drill processing device in this application, the length of the pin bar is maximized, thereby achieving the goal of increasing the output of water drill processing.

[0018] In some embodiments, the operation time of the rotary table position is used as the cycle time reference for the processing line, and a preset reference cycle time R is used. X =S Z +S A Based on the reference cycle time and the machining length L of any facet of the water drill, obtain the grinding wheel diameter D1 of the rough grinding station, so that the production time of the rough grinding station Ry = S. Z +y+ ≤R X ;

[0019] ;

[0020] N is the number of facets in the water drill, L is the machining length of any facet in the water drill, n1 is the grinding wheel speed, and t a R is the minimum allowable feed time for the needle bar. X As the baseline beat, S Z To minimize the time required for the needle bar to move from one position to the next, S A The time required for the rotary table to complete one rotation / spin-out operation is y, where y is the preset processing time for the rough grinding machine.

[0021] Specifically, through the adjustment and optimization of the layout of the entire automated processing device in this application, the rotary table station becomes the optimal production cycle reference station among all the machine positions in this application. Since it only needs to perform rotation or return operations in addition to the common needle plate drive operation, and the time of rotation or return operations cannot be further optimized, the operation time of the rotary table station becomes the preset reference cycle time R. XAt this point, in order to further reduce the production cycle time, it is necessary to reduce the operating time of the adhesive bonding station, the feeding station, the rough grinding station, the fine grinding station, the first polishing station, the second polishing station, and the unloading station. Therefore, another concept of this application is to reduce the grinding operation time of the rough grinding station by increasing the size of the grinding wheel, and to obtain the minimum grinding wheel diameter based on considerations of grinding wheel speed and grinding quality, so that the grinding wheel diameter meets the requirements of balanced cycle time.

[0022] It is worth noting that t a The minimum allowable feed time for the pin array refers to setting the grinding surface of the grinding wheel in the rough grinding mill position close enough to the pin array to minimize the pin array feed distance and thus the pin array feed time.

[0023] Furthermore, this application provides a high-efficiency automatic water drill processing device, comprising the following steps:

[0024] S1, according to the preset baseline rhythm R X The feed speed of each machine position is preset so that the actual processing time of the adhesive gluing machine position, feeding machine position, coarse grinding machine position, fine grinding machine position, first polishing machine position, second polishing machine position and unloading machine position are S1, S2, S3, S4, S5, S6 and S7 respectively.

[0025] S2. Real-time collection of actual processing time and actual yield rate for each machine station, respectively. , , , , , , , and y1, y2, y3, y4, y5, y6, y7;

[0026] S3. Using the ratio of the reciprocal of the actual yield rate as the adjustment weight, obtain the actual baseline cycle time. ,

[0027] =S Z ) / ( + + + + + + );

[0028] S4. Based on the actual benchmark beat The feed speed of each machine position is adjusted in real time.

[0029] Specifically, another concept of this application is to adjust the feed speed of each machine station in real time by adjusting the actual yield rate and the actual processing time, so as to balance the yield rate and production cycle of each machine station, and ensure the yield rate of water drilling while meeting production efficiency.

[0030] Furthermore, the first and second polishing stations each complete the polishing operation of the N / 2 facets.

[0031] Specifically, polishing takes much longer, generally exceeding grinding time by 1.5 times. Therefore, to address the time bottleneck in polishing, the polishing process for rhinestone facets is divided into two machine positions: one polishing machine completes half of the rhinestone facets, and a second polishing machine completes the other half, thus balancing the processing time across the polishing machine positions.

[0032] Furthermore, the outer diameter of the polishing sleeve of the polishing wheel at one polishing position is set to D3, and the inner diameter of the polishing sleeve of the polishing wheel at one polishing position is set to D2, where D3 > D2 > D1;

[0033] ;

[0034] n2 is the rotational speed of the blast wheel.

[0035] Specifically, another concept of this application is to further balance the processing time of the polishing machine position by designing the diameter of the polishing wheel.

[0036] Furthermore, this application provides a high-efficiency automatic water drilling device, comprising: adjusting the rotational speed of the polishing wheel according to the consumption i of the polishing abrasive. ;

[0037] 0 ≤ i < D3 - D2.

[0038] Specifically, the polishing wheel in the polishing wheel position is different from the grinding wheel in the grinding wheel position. The grinding wheel surface is prepared by diamond fragment doping, which has virtually no wear. However, the polishing wheel uses polishing abrasive to achieve better polishing results. The polishing abrasive will wear down over time. In order to ensure that the polishing contact area meets the polishing requirements, the speed of the polishing wheel is adjusted to compensate for the wear of the polishing abrasive and improve the polishing quality of the water rhinestone.

[0039] Furthermore, .

[0040] Specifically, the polishing surface of the polishing wheel in the first polishing position is also set at the shortest feed distance from the pin row, so that the pin row feed distance is minimized, thereby reducing the pin row feed time. However, as the polishing abrasive is continuously consumed, the distance between the pin row and the polishing surface becomes farther and farther, and the pin row feed time will gradually increase. In order to ensure that the processing time of the polishing position still meets the requirements of the preset reference cycle, the inner diameter of the polishing sleeve is limited by a formula.

[0041] Furthermore, the number of polishing stations required for the polishing process is related to the polishing time required to complete all facets N of the water drill;

[0042] when >S A -t a At that time, three additional launch positions were added.

[0043] Specifically, as the number of polishing facets increases, such as from 8 facets to 12, 18, or 24 facets, additional polishing stations can still be added in order to maintain a balanced polishing time.

[0044] Furthermore, based on the preset benchmark cycle, when the facet is raised, the number of grinding positions is increased.

[0045] In some embodiments, the polishing wheel speed n2 is determined based on the water-drill polishing yield y5, where y5 ≥ 50%.

[0046] Specifically, if the polishing wheel speed is too fast, it will affect the yield rate of rhinestone polishing. Therefore, the polishing wheel speed is adjusted according to the rhinestone polishing yield rate.

[0047] It is worth noting that, for the purpose of explaining the operating procedures for each machine station, please refer to the following:

[0048] Adhesive bonding process: The adhesive powder in the powder box is spread evenly. After the needle bar is transferred to the adhesive bonding position by the drive mechanism, the needle bar is controlled to feed into the powder box. The heated needle bar comes into contact with the spread adhesive powder, so that the adhesive powder adheres to the needle bar.

[0049] Feeding process: The material box contains bead blanks to be fed. After the needle array is transferred to the feeding position by the drive mechanism, the mating mechanism below the material box is controlled to feed towards the needle array. Through the cooperation between the mating mechanism and the needle array, the bead blanks are fed to the needle array.

[0050] Rinsing process: The water flow cleans the bead blanks on the pin array in the drive to prevent excess glue powder from adhering and affecting the subsequent grinding or polishing effect of the bead blanks.

[0051] Grinding process: After the needle plate is transferred to the rough grinding or fine grinding position by the drive mechanism, the needle plate is controlled to feed towards the rotating grinding wheel, and the multiple arranged bead blanks are ground as a whole by the moving grinding wheel surface.

[0052] Polishing process: After the needle array is transferred to the first or second polishing position by the drive mechanism, the needle array is controlled to feed towards the rotating polishing wheel, and the multiple arranged bead blanks are polished as a whole by the moving polishing wheel surface.

[0053] High-frequency heating process: The needle array in the drive is heated by high frequency to make the adhesive powder in an active state;

[0054] Material feeding process: After the needle array is transferred to the feeding machine position by the drive mechanism, the bead blank brush set at the feeding machine position feeds the needle array. The rotating bead blank brush brushes the bead blanks on the needle array, causing them to fall into the receiving box.

[0055] In summary, this application provides a high-efficiency automatic water drill processing device. By adjusting the sequence of processes and the layout of machine positions in existing technologies, the adhesive bonding process is separated from the turntable machine position. This allows the turntable machine position to perform only rotational or slewing operations, eliminating the adhesive bonding operation and reducing the operational complexity of the turntable machine position. Its station time is now only related to the basic needle drive and slewing operations, thus balancing the production cycle of the entire production line, reducing cycle time, and improving production efficiency. Simultaneously, this application integrates the rinsing process, which does not require station time, into the turntable machine position, filling the station gap left by the removal of the adhesive bonding process. This eliminates the need for additional machine positions in the dual-line cycle processing structure, avoiding unreasonable cost increases. Furthermore, this application designs the wheel diameters for the rough grinding machine position, fine grinding machine position, first polishing machine position, and second polishing machine position, controlling the processing time of the grinding and polishing processes. Without affecting the water drill processing quality, the processing time of the grinding and polishing processes is aligned with a preset benchmark cycle time, thereby improving the processing efficiency of the water drill production line and increasing water drill output. This application also adjusts the preset benchmark cycle time based on the actual processing time and actual yield rate, thereby achieving a balance between water drill processing efficiency, production output, and water drill processing quality. This ensures both production efficiency and a high yield rate during the water drill production process. Attached Figure Description

[0062] The following is in conjunction with the appendix Figures 1 to 5 This application will be described in detail.

[0063] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0064] This application provides a high-efficiency automatic water drill processing device, which has at least the advantages of high processing efficiency, sufficient output, and controllable yield.

[0065] Please see Figure 1 As shown, Figure 1 A schematic diagram of an automated water drill production line provided by existing technology.

[0066] Specifically, water-drilling production lines often employ a dual-line circulating processing structure to achieve fully automated processing cycles and improve space utilization. The common structure of a dual-line circulating system involves separating the two production lines symmetrically. One line starts with the gluing process and ends with the unloading process, while the other line uses the same layout, also starting with the gluing process and ending with the unloading process. This dual-line circulating system has become the industry standard. Refer to the structure of authorized patent CN104551915B, which also integrates the gluing station into a turntable (referred to as a rotating device in this patent). Although its dual-line circulating structure uses transition stations for cyclical coordination, the overall structural pattern is basically similar. The mechanical structure of the device provided in this application can be understood by referring to its station structure.

[0067] Please see Figure 2 As shown, Figure 2 This application provides a schematic diagram of the structure of a high-efficiency water drill automatic processing device.

[0068] Specifically, based on the analysis of the processing time occupied by the process, this application abandons the concept of integrating the turntable position with the gluing process in the prior art. Instead, it separates the gluing process from the turntable position, reducing the working time of the turntable position. At the same time, it integrates the rinsing process, which does not occupy the working time, into the turntable position, so as to achieve the goal of neither adding a new position nor increasing equipment costs, but also reasonably adjusting the production cycle.

[0069] In this application, the production line is no longer located at the rotary table position as in the prior art, but at the end of another operating line (see the dotted line indicating the separation of the two production lines). After passing through the gluing station and the loading station, it enters the rotary table position via the coordination station. It is understood that the coordination station does not perform any operation on the needle assembly, while the rinsing station only rinsing the moving needle assembly with a continuous water outlet. Neither station occupies the working time of the rotary table position. Therefore, the working time of the rotary table position is improved. After the needle assembly passes the rotary table position, it is rotated to enter the beginning of that operating line, and then passes through the rough grinding station, fine grinding station, first polishing station, second polishing station, high-frequency heating station, and unloading station in sequence, completing the single-line processing of the water drill according to the efficient automatic water drill processing device provided in this application. The needle assembly then enters the gluing station of another production line to begin processing on that line, forming a double-line cycle. By splitting and rearranging the processes and machine positions in this application, each machine position only needs to be responsible for its own operation, except for the common needle row drive operation. This improves the working time of each machine position, reduces the production cycle time in the fully automated water drill production process, and increases the output of water drills.

[0070] Furthermore, please refer to Table 1 below, which is a comparison table of the production cycle time of this application and the prior art.

[0071] Table 1 Comparison of Working Time between This Application and Prior Art

[0072]

[0073] As shown in Table 1, the high-efficiency automatic water drill processing device provided in this application can effectively reduce the production cycle from 2.38s to 1.92s compared to the water drill processing devices provided in the prior art. That is, by using a set of processing devices provided in this application, the output can be increased by 1.24 times per day.

[0074] Clearly, the high-efficiency automatic water drill processing device provided in this application effectively balances the processing time of each machine station in the production line, thereby reducing the overall production cycle and significantly increasing the output of water drills.

[0075] Furthermore, this application provides a dual-line circulating processing structure, wherein any processing line sequentially includes an adhesive gluing station, a feeding station, a turntable station, a coarse grinding station, a fine grinding station, a first polishing station, a second polishing station, a high-frequency heating station, and a discharging station; the discharging station of one processing line is connected to the adhesive gluing station of another processing line to form a dual-line circulation.

[0076] Furthermore, since the pin array drive is a common transmission time, reducing its drive time or increasing the number of pin arrays can improve the output of water drilling. Therefore, this application moves the mounting position of the rotary table away from the rough grinding machine position, and extends the length of the pin array based on its original dimensions to reach the maximum allowable length for rough grinding machine processing.

[0077] It is worth noting that due to the limitations of the existing water drill production line structure, the pin array cannot be extended to the maximum permissible length, which is usually 900mm. This application relocates the turntable position, thereby extending the pin array length to the maximum permissible length of 950mm without affecting the pin array drive time, increasing water drill output by 1.06 times.

[0078] Please see Figure 3 As shown, Figure 3 Cross-sectional schematic diagrams of the adhesive application station (A), powder application station (B), and unloading station (C) provided in the embodiments of this application.

[0079] Specifically, the adhesive application process involves spreading the adhesive powder inside the powder box. After the needle column is driven to the adhesive application station, it is fed into the powder box, bringing the heated needle column into contact with the spread adhesive powder, causing the powder to adhere to the needle column. Figure 3 Figure A shows a cross-sectional schematic diagram of the adhesive application station, which includes a frame, a powder box, a powder box leveling mechanism, a needle row drive mechanism, and a needle row track. The needle row track is shared by a running line on one side, allowing the needle rows to flow along it. The powder box leveling mechanism is used to level the adhesive powder inside the powder box, and both the powder box leveling mechanism and the powder box are mounted on the frame. The needle row drive mechanism is mounted on the frame and drives the needle rows flowing to the adhesive application station to feed towards the powder box, thereby completing the powder application operation.

[0080] The feeding process refers to the process where the bead blanks, containing beads to be fed into the material box, are moved to the feeding position by the drive mechanism after the needle array is moved to the feeding position. The cooperating mechanism below the material box then feeds the beads onto the needle array. Figure 3 Figure B shows a cross-sectional schematic diagram of the feeding station, which includes a frame, a material box, and a mating mechanism. The material box and the mating mechanism are located on the frame. The material box contains the bead blanks to be processed, and the mating mechanism is provided with a locking slot that engages with the bead blanks on the needle array. The mating mechanism is driven to feed towards the needle array to complete the feeding of the bead blanks.

[0081] The unloading process refers to the process where, after the needle array is transferred to the unloading station by the drive mechanism, the bead blank brush at the unloading station feeds the needle array. The rotating bead blank brush agitates the beads on the needle array, causing them to fall into the receiving box. Figure 3 Figure C shows a cross-sectional schematic diagram of the unloading station. It includes a frame, a receiving box, and a bead brush. The receiving box and the bead brush are located on the frame. The bead brush is driven to feed towards the needle bar, brushing the bead clamped on the needle bar, causing it to fall off the needle bar and into the receiving box.

[0082] Since both the flushing process and the high-frequency heating process involve operating on the moving needle array, it is only necessary to align the water outlet or heating port with the working part of the needle array. Therefore, the structure of the needle array is not shown in this application, but can be understood by referring to other machine positions.

[0083] Please see Figure 4 As shown, Figure 4 Cross-sectional schematic diagrams of the coarse grinding mill station (D) and the first polishing mill station (E) provided in the embodiments of this application.

[0084] Specifically, the grinding process refers to the process where, after the needle array is transferred to the rough or fine grinding position by the drive mechanism, it is fed towards the rotating grinding wheel, and the moving grinding wheel surface is used to grind multiple arranged bead blanks as a whole. The polishing process refers to the process where, after the needle array is transferred to the first or second polishing position by the drive mechanism, it is fed towards the rotating polishing wheel, and the moving polishing wheel surface is used to polish multiple arranged bead blanks as a whole. Here, D1 refers to the diameter of the grinding wheel in the rough grinding position, D2 refers to the inner diameter of the polishing sleeve in the first polishing position, and D3 refers to the outer diameter of the polishing sleeve in the first polishing position. The polishing sleeve is fitted onto the roller by a sleeve connection.

[0085] Furthermore, as shown in Table 1, without considering the common time of the needle drive, the working times of each machine position—adhesive bonding, material feeding, turntable water rinsing, rough grinding, fine grinding, first polishing, second polishing, heating, and unloading—are different. Since the rotation or turning operation of the turntable position during the turntable water rinsing process is limited by the motor speed and mechanism stability, its working time is basically fixed. In addition, operations such as adhesive bonding, material feeding, and unloading only require controlling the feed operation, and their working time is less than that of the turntable position. Therefore, the turntable position can be used as a benchmark to determine the production cycle. At this point, the rough grinding position, fine grinding position, first polishing position, and second polishing position become bottleneck processes restricting the production cycle, preventing further increases in the output of water drills.

[0086] Furthermore, using the operation time of the rotary table position as the cycle time benchmark for the machining line, a preset benchmark cycle time R is established. X =S Z +S A Therefore, to ensure the time Ry=S for the rough grinding station... Z +y+ ≤RX That is, processing time y≤R X -S Z -ta=S A -t a .

[0087] Furthermore, *D1*y* =N*L, then When D1 takes a value greater than When the final production time of the coarse grinding mill is Ry≤R X This solves the bottleneck problem of the rough grinding machine position, and its final production time is less than that of the rotary table position, thus making the production cycle of the device provided in this application shorter and the output of water drills higher.

[0088] N is the number of facets in the water drill, L is the machining length of any facet in the water drill, n1 is the grinding wheel speed, and t a R is the minimum allowable feed time for the needle bar. X As the baseline beat, S Z To minimize the time required for the needle bar to move from one position to the next, S A The time required for the turntable position to complete one rotation / slew operation.

[0089] Specifically, the grinding efficiency of the bead blank is mainly related to the grinding wheel diameter and the grinding wheel speed, and the grinding wheel speed will affect the grinding quality of the bead blank. Therefore, this application treats the grinding wheel speed as a constant and reduces the grinding time by increasing the grinding wheel diameter, as shown in Table 2.

[0090] Table 2 Relationship between grinding wheel diameter and working time

[0091]

[0092] As shown in Table 2, as the diameter of the grinding wheel increases, the working time of the grinding wheel position decreases.

[0093] In theory, when the diameter of the grinding wheel in the coarse grinding mill is between 370-400mm, the working time of the grinding wheel can be matched with the working time of the turntable, thereby obtaining the optimal production cycle of 1.76s.

[0094] It's worth noting that a larger grinding wheel diameter isn't always better. While a larger diameter provides a shorter working time, it also increases the required installation space for the machine frame, raising manufacturing costs. Therefore, it's sufficient to appropriately increase the grinding wheel diameter, ensuring the reduction in working time aligns with the preset benchmark cycle time, while keeping the diameter within the acceptable range for the machine frame.

[0095] Please see Figure 5 As shown, Figure 5 This application provides an embodiment of the adjustment diagram for the actual reference beat.

[0096] Specifically, this application includes the following steps:

[0097] Through step S1, according to the preset benchmark rhythm R X The feed speed of each machine position is preset so that the feed times of the adhesive bonding machine position, the feeding machine position, the coarse grinding machine position, the fine grinding machine position, the first polishing machine position, the second polishing machine position and the unloading machine position are S1, S2, S3, S4, S5, S6 and S7 respectively.

[0098] Then, using step S2, the actual processing time and actual yield of each machine station are collected in real time, respectively. , , , , , , , and y1, y2, y3, y4, y5, y6, y7;

[0099] Then, through step S3, the actual baseline cycle time is obtained by using the ratio of the reciprocal of the actual yield rate as the adjustment weight. ,

[0100] =S Z ) / ( + + + + + + );

[0101] Finally, through step S4, based on the actual benchmark beat... The feed speed of each machine position is adjusted in real time.

[0102] Furthermore, in the actual operation of the high-efficiency automatic water drill processing device provided in this application, although the operation time of the rotary table position is used as the preset benchmark cycle time, which can effectively increase the water drill processing output, in actual operation, the actual processing time of each position is often different due to the error of the drive mechanism. At the same time, the dwell time at the working position will affect the yield rate of water drills at that position.

[0103] Therefore, this application uses the yield rate of water drills at each machine position as an adjustment ratio, and adjusts the preset benchmark cycle time by calculating the actual processing time, thereby balancing the water drill output and the water drill yield rate, which both increases the output of water drills and ensures the yield rate of water drills.

[0104] Furthermore, the actual yield rate of each machine station during the production and processing of water rhinestones can be obtained by continuously shooting and comparing images of the water rhinestone production process using a high-frequency camera, while the actual processing time can be obtained through sensors.

[0105] Furthermore, the first and second polishing stations each complete the polishing operation of the N / 2 facets.

[0106] Furthermore, the outer diameter of the polishing sleeve of the polishing wheel at one polishing position is set to D3, and the inner diameter of the polishing sleeve of the polishing wheel at one polishing position is set to D2, where D3 > D2 > D1;

[0107] ;

[0108] n2 is the rotational speed of the blast wheel.

[0109] Specifically, the diameter of the polishing wheels at the first and second polishing positions will also affect the polishing operation time.

[0113] Furthermore, this application provides a high-efficiency automatic water drilling device, comprising: adjusting the rotational speed of the polishing wheel according to the consumption i of the polishing abrasive. ;

[0114] 0 ≤ i < D3 - D2.

[0115] Specifically, as the abrasive wears out, the feed time of the pin array will continue to increase. In order to compensate for the working time of the polishing machine, the speed of the polishing wheel is adjusted appropriately to make the speed of the polishing wheel faster.

[0116] Furthermore, the number of polishing stations required for the polishing process is related to the polishing time required to complete all facets N of the water drill;

[0117] when >S A -t a At that time, three additional launch positions were added.

[0118] The polishing wheel speed n2 is determined based on the water-drill polishing yield y5, where y5≥50%.

[0119] Specifically, considering the polishing quality, the polishing wheel speed should not be increased indefinitely; the goal should be to achieve a high yield rate for water-polished diamonds.
