Description

[0001] This application is a divisional application. The application number of the original application is CN202311526173.2, the application date is 2023.11.14, and the subject of the invention is a high-efficiency water drill automatic processing device. Technical Field

[0002] The present application relates to the field of water drill processing and production, and in particular to a high-efficiency water drill automatic processing device. Background Art

[0003] Rhinestones are also known as crystal diamonds and rhinestones. The main component of rhinestones is crystal glass, which is a kind of jewelry accessory obtained by cutting artificial crystal glass into diamond facets. This material is very popular because it is relatively economical and has a dazzling diamond-like visual effect. It is widely used in low- and medium-end jewelry design, so rhinestones are mainly processed in batches.

[0004] Authorized patent CN104551915B discloses a fully automatic water drill grinding and polishing machine, which discloses a first grinding and polishing production line and a second grinding and polishing production line that are arranged opposite to each other. The two sides of the two grinding and polishing production lines are connected by a rotating device, and the two glue powder application stations are arranged at the starting end of the production line. During the water drill processing, the circulation of the water drills in the production line on either side is driven by a common driving device, and the needle row (called a clamp in the patent) circulates between multiple stations in turn to complete the grinding and polishing of the water drill. Although the common time for the needle row to circulate is the same, the time spent between different processes is different due to different execution operations and quality requirements. This also leads to differences in the time the needle row stays at different stations. In order to ensure the normal circulation of the entire production line, only the station with the longest station stay time can be used as the benchmark as the production rhythm of the entire production line, which leads to a longer processing time for the water drill due to the existence of bottleneck processes, thereby restricting the production efficiency and output of the water drill. In addition, the grinding and polishing processes have requirements on the processing time of water rhinestones, especially the polishing process. When the grinding or polishing time is not enough, it will directly affect the quality of water rhinestones.

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

[0006] The present application aims to solve the technical problem that in a water rhinestone production line with a dual-line circulation processing structure, the water rhinestone production efficiency is low and it is difficult to balance the production efficiency and output quality due to the long production cycle. An efficient water rhinestone automatic processing device is provided, which has at least the advantages of high processing efficiency, sufficient output, and controllable yield rate.

[0007] The present application provides a high-efficiency automatic processing device for water diamonds, which is configured as a double-line circulation processing structure, including a turntable, gluing, loading, grinding, polishing, high-frequency heating and unloading machine positions, including:

[0008] The loading machine position is set before the turntable machine position. After the needle row completes the bead embryo clamping at the loading machine position, it is driven by the driving mechanism to enter the turntable machine position;

[0009] The turret position includes rotation operation and rotation operation; the rotation operation means that after the needle row enters the turret position, its turntable rotates 180°, driving the needle row from the end of one running line to the beginning of another running line; the rotation operation means that after the needle row entering the beginning is driven by the driving structure of the running line to enter the grinding process, its turntable rotates 180° to recover and wait for the next needle row to enter the turret position;

[0010] The flushing process is integrated into the turntable machine position, including a water outlet structure, and the water outlet of the water outlet structure is arranged at the beginning of another rotary line, before entering the grinding process.

[0011] Specifically, one of the concepts of the present application is to continue to use various processing coordination structures of the existing water diamond production line, and through the optimization of the process position and machine layout, eliminate the bottleneck process in the automatic processing device, reduce the production cycle, and improve the water diamond processing efficiency, thereby achieving the purpose of increasing the output of water diamonds.

[0012] First, the present application separates the gluing process from the turntable position, so that the turntable position only performs rotation or rotation operations, and no longer performs gluing operations, thereby reducing the complexity of the turntable position's operation execution, so that its station time is only related to the basic needle row drive and rotation operations, and balances the production rhythm of the entire production line, reduces the production rhythm time, and improves production efficiency. At the same time, the present application also integrates the flushing process that does not require station time into the turntable position, fills the station vacancy caused by the separation of the gluing process, and eliminates the need to add additional positions for the entire double-line circulation processing structure, avoiding unreasonable cost increases.

[0013] Furthermore, any processing line is arranged in sequence as a gluing machine position, a loading machine position, a turntable machine position, a coarse grinding machine position, a fine grinding machine position, a first polishing machine position, a second polishing machine position, a high-frequency heating machine position and a unloading machine position; the unloading machine position of one processing line is connected with the gluing machine position of another processing line to form a double-line circulation.

[0014] Specifically, the present application belongs to a dual-line circulation 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 an efficient water drill automatic processing device provided by the present application.

[0015] Furthermore, the installation position of the turntable machine is moved away from the rough grinding machine, and the length of the needle row is extended on the basis of the original size of the needle row to reach the maximum allowable length of the rough grinding machine.

[0016] Specifically, another concept of the present application is that, based on the adjustment of the production line structure, the gluing process is no longer restricted by the turntable position, so that the drive time of the needle row can be adjusted when the dwell time of the turntable position only includes the rotation operation or rotation operation time plus the needle row drive time. By lengthening the needle row, the moving distance of the needle row is balanced and the capacity of one bead embryo processing is increased.

[0017] It is worth noting that the output of rhinestones is not only related to the production cycle, but also to the number of rhinestones clamped at one time. The more rhinestones the needle row clamps at one time, the higher the output of rhinestones. Therefore, based on the adjustment and optimization of the structure of the automatic processing device for rhinestones in this application, the length of the needle row is maximized, thereby achieving the purpose of increasing the output of rhinestone processing.

[0018] In some embodiments, the operating time of the rotary table is used as the beat reference of the processing line, and the preset benchmark beat R X =S Z +S A According to the reference beat and the processing length L of any facet of the diamond, the grinding wheel diameter D1 of the rough grinding machine is obtained, so that the production time Ry of the rough grinding machine is Ry = S Z +y+t a ≤R X ;

[0019]

[0020] N is the number of facets of the rhinestone, L is the processing length of any facet of the rhinestone, n1 is the grinding wheel speed, t a The minimum feed time allowed for the needle row, R X is the base beat, S Z S is the shortest time for the needle row to move from one position to the next. A It is the time required for the rotary table machine to complete one rotation operation / swivel operation, and y is the preset processing time of the rough grinding machine.

[0021] Specifically, after the present application adjusts and optimizes the layout of the entire automatic processing device, the turntable station becomes the optimal production rhythm reference station among all the stations of the present application. Since it only needs to perform rotation operation or rotation operation in addition to the common needle row driving operation, and the time of rotation operation or rotation operation cannot be further optimized, the operation time of the turntable station becomes the preset reference rhythm R X. At this time, in order to further reduce the production cycle, it is necessary to reduce the operation time of the gluing machine, loading machine, coarse grinding machine, fine grinding machine, first polishing machine, second polishing machine and unloading machine. Therefore, another concept of the present application is to reduce the grinding operation time of the coarse grinding machine by increasing the size of the grinding wheel of the coarse grinding machine, and based on the consideration of the grinding wheel speed and the grinding quality, obtain the minimum grinding wheel diameter size so that the grinding wheel diameter meets the demand of the balanced cycle.

[0022] It is worth noting that t a To allow the minimum feed time for the needle row means that the grinding surface of the grinding wheel of the rough grinding machine is set close enough to the needle row so that the needle row feed distance is the shortest, and thus the needle row feed time is the shortest.

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

[0024] S1, according to the preset reference beat R X , preset the feed speed of each machine position, so that the actual processing time of the gluing machine position, loading 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, S7 respectively;

[0025] S2, real-time collection of actual processing time and actual yield rate of each machine position, respectively S 1′ , S 2′ , S 3′ , S 4′ , S 5′ , S 6′ , S 7′ , and y1, y2, y3, y4, y5, y6, y7;

[0026] S3. Use the ratio of the inverse of the actual yield rate as the adjustment weight to obtain the actual benchmark beat R X′ ,

[0027]

[0028] S4. According to the actual benchmark beat R X′ , and adjust the feed speed of each machine position in real time.

[0029] Specifically, another concept of the present application is to adjust the feed speed of each machine position in real time according to the actual yield rate and the actual processing time, balance the yield rate and production rhythm of each machine position, and ensure the yield rate of water drill processing while meeting the production efficiency.

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

[0031] Specifically, since the polishing process takes longer, generally 1.5 times longer than the grinding process, in order to solve the time bottleneck problem in the polishing process, the polishing process of the rhinestone facets is divided into two machine positions, that is, the first polishing machine position completes the processing of half of the rhinestone facets, and then the second polishing machine position completes the processing of the other half of the rhinestone facets, so as to achieve the purpose of balancing the processing time of the polishing machine position.

[0032] Furthermore, a polishing wheel of a polishing machine is provided with an outer diameter of D3 and an inner diameter of D2, wherein D3>D2>D1;

[0033]

[0034] n2 is the speed of the throwing wheel.

[0035] Specifically, another concept of the present application is to further balance the processing time of the polishing machine through the design of the polishing wheel diameter.

[0036] Furthermore, the present application provides a high-efficiency automatic water drill processing device, comprising: adjusting the grinding wheel speed according to the consumption i of the grinding abrasive,

[0037] 0≤i<D3-D2.

[0038] Specifically, the polishing wheel of the polishing machine is different from the grinding wheel of the grinding machine. The grinding wheel surface of the grinding wheel is prepared by doping with diamond fragments, and there is basically no loss. In order to achieve better polishing effect, the polishing wheel is polished with abrasives. The abrasives will be lost as the polishing time goes by. In order to make the polishing contact area meet the polishing requirements, the polishing wheel speed is adjusted to compensate for the water diamond contact area after the abrasive is worn, thereby improving the water diamond polishing quality.

[0039] Furthermore,

[0040] Specifically, the polishing surface of the polishing wheel of a polishing machine is also set at the shortest feed distance from the needle row, so that the needle row feeding distance is the shortest, thereby reducing the needle row feeding time. However, with the continuous consumption of the abrasive, the distance between the needle row and the polishing surface is getting farther and farther, and the needle row feeding time will gradually increase. In order to ensure that the processing time of the polishing machine still meets the requirements of the preset benchmark beat, the inner diameter of the abrasive is limited by a formula.

[0041] Furthermore, the number of machine positions required for the polishing process is related to the polishing time required to complete all facets N of the rhinestone;

[0042] when When the aircraft is launched, three more landing positions will be added.

[0043] Specifically, as the number of polishing facets increases, such as from 8 facets to 12 facets, 18 facets, 24 facets, etc., in order to still achieve the goal of balancing the polishing processing time, new polishing machine positions can still be added.

[0044] Furthermore, according to the preset reference beat, when the facet is raised, the grinding machine position is increased.

[0045] In some embodiments, the polishing wheel speed n2 is determined according to the diamond polishing yield rate y5, where y5≥50%.

[0046] Specifically, when the rotation speed of the polishing wheel is too fast, the polishing yield rate of the rhinestone will be affected. Therefore, the rotation speed of the polishing wheel is adjusted according to the polishing yield rate of the rhinestone.

[0047] It is worth mentioning that in order to explain the operating procedures of each machine position, please refer to the following:

[0048] Gluing process: the glue powder in the powder box is flattened, and after the needle row is transferred to the gluing machine position through the driving mechanism, the needle row is controlled to feed toward the powder box, and the heated needle row is brought into contact with the flattened glue powder, so that the glue powder adheres to the needle row;

[0049] Loading process: the material box contains the pearl embryos to be loaded. After the needle row is transferred to the loading position through the driving mechanism, the matching mechanism under the material box is controlled to feed toward the needle row. Through the cooperation between the matching mechanism and the needle row, the pearl embryos are loaded onto the needle row.

[0050] Flushing process: Use water flow to clean the bead embryos on the driven needle row to avoid the adhesion of excess rubber powder, which will affect the subsequent grinding or polishing effect of the bead embryos;

[0051] Grinding process: After the needle row is transferred to the rough grinding or fine grinding position through the driving mechanism, the needle row is controlled to feed to the rotating grinding wheel, and the multiple arranged pearl embryos are ground as a whole through the moving grinding wheel surface;

[0052] Polishing process: After the needle row is transferred to the first or second polishing machine position through the driving mechanism, the needle row is controlled to feed to the rotating polishing wheel, and the multiple arranged pearl embryos are polished as a whole through the moving polishing wheel surface;

[0053] High-frequency heating process: The needle row in the driving process is heated by high frequency to make the rubber powder active;

[0054] Unloading process: After the needle row is transferred to the unloading machine position through the driving mechanism, the bead embryo brush set at the unloading machine position feeds toward the needle row, and the bead embryo on the needle row is brushed by the rotating bead embryo brush, so that it falls into the receiving box.

[0055] In summary, the present application provides an efficient automatic processing device for water drills. By adjusting the sequence of each process and the layout structure of each machine position in the prior art, the gluing process is separated from the turntable machine position, so that the turntable machine position only performs rotation operation or rotation operation, and no gluing operation is performed in addition, the complexity of the operation execution of the turntable machine position is reduced, and its station time is only related to the basic needle row drive and rotation operation, and the production rhythm of the entire production line is balanced, the production rhythm time is reduced, and the production efficiency is improved. At the same time, the present application also integrates the flushing process that does not need to occupy the station time into the turntable machine position, fills the station vacancy caused by the stripping of the gluing process, so that the entire double-line circulation processing structure does not need to add additional machine positions, avoiding unreasonable cost increases. In addition, the present application also designs the wheel diameters of the rough grinding machine position, the fine grinding machine position, the first polishing machine position and the second polishing machine position, so that the processing time of the grinding and polishing process is controlled, and the processing time of the grinding and polishing process is aligned with the preset reference rhythm without affecting the processing quality of the water drill, thereby improving the processing efficiency of the water drill production line and increasing the output of water drills. The present application also adjusts the preset reference beat according to the actual processing time and the actual yield rate, thereby achieving a balance between the water rhinestone processing efficiency, production output, and water rhinestone processing quality. While ensuring production efficiency, the yield rate in the water rhinestone production process is also guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The following is combined with Figures 1 to 5 , a detailed description of this application is given.

[0063] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0064] The present 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 rate.

[0065] See also Figure 1 As shown, Figure 1 Schematic diagram of the automatic processing production line of water rhinestones provided by the prior art.

[0066] Specifically, water drill processing production lines often adopt a dual-line circulation processing structure to achieve fully automatic processing cycles and improve site utilization. The general structure of the dual-line circulation is to separate the dual production lines with a symmetry line. That is, one side of the production line starts from the gluing process and ends at the unloading process, and the other production line also adopts such a layout, starting from the gluing process and ending at the unloading process. This kind of dual-line circulation has basically become a common structure in the industry. You can refer to the structural layout of the authorized patent CN104551915B, which also integrates the gluing station into the turntable position (the patent is called a rotating device). Although its dual-line circulation structure uses a transfer matching station for circulation matching, the overall structural pattern is basically similar, and you can refer to its station structure to understand the mechanical structure of the device provided in this application.

[0067] See also Figure 2 As shown, Figure 2 A schematic structural diagram of a high-efficiency automatic water drill processing device provided in an embodiment of the present application.

[0068] Specifically, based on the analysis of the processing time occupied by the process, the present application abandons the idea of ​​integrating the turntable machine position with the gluing process in the prior art, and instead separates the gluing process from the turntable machine position, thereby reducing the operating time of the turntable machine position. At the same time, the flushing process that does not occupy the operating time is integrated into the turntable machine position, thereby achieving the purpose of not adding new machines, increasing equipment costs, and reasonably adjusting the production rhythm.

[0069] That is, the first production line of the present application is no longer located at the turntable position as in the prior art, but is located at the tail end of the operating line on the other side (see the dotted line guide, the two production lines are separated by the dotted line). After passing through the gluing machine position and the loading machine position in sequence, it enters the turntable position through the matching station. It can be understood that the matching station does not perform any operation on the needle row, and the flushing station only flushes the moving needle row through the outlet that continuously discharges water. Both stations do not occupy the working time of the turntable position. Therefore, the working time of the turntable position is improved. After the needle row passes through the turntable position, the needle row enters the beginning of the operating line on this side through the rotation operation, and then passes through the coarse grinding machine position, fine grinding machine position, first polishing machine position, second polishing machine position, high-frequency heating machine position, and unloading machine position in sequence, completing the single-line processing of the water drill in a high-efficiency water drill automatic processing device provided in the present application. The needle row then enters the gluing machine position of another production line and starts the processing operation of another line, forming a double-line cycle. By splitting and re-arranging the processes and machine positions in this application, each machine position, in addition to the common needle row driving operation, is only responsible for the operation of its own position, thereby improving the working time of each machine position, reducing the production rhythm in the fully automatic production process of water drills, and increasing the output of water drills.

[0070] Further, please refer to Table 1 below, which is a comparison table of the production rhythm of the present application and the prior art.

[0071] Table 1 Comparison of working time between this application and prior art

[0072]

[0073] As can be seen from Table 1, the efficient water drill automatic processing device provided by the present application can effectively reduce the production cycle from 2.38s to 1.92s compared to the water drill processing device provided by the prior art. That is, through a set of processing devices provided by the present application, the output can be increased by 1.24 times in terms of days.

[0074] Obviously, the efficient automatic water drill processing device provided by the present application effectively balances the processing time of each machine position in the production process of the processing production line, thereby reducing the overall production rhythm and greatly improving the water drill output.

[0075] Furthermore, the present application provides a dual-line circulation processing structure, in which any processing line includes a gluing machine position, a loading machine position, a turntable machine position, a coarse grinding machine position, a fine grinding machine position, a first polishing machine position, a second polishing machine position, a high-frequency heating machine position and a unloading machine position in sequence; the unloading machine position of one processing line is connected with the gluing machine position of another processing line to form a dual-line circulation.

[0076] Furthermore, the needle row drive is used as a common transmission time, and the reduction of its driving time or the increase of the number of needle row clamps can improve the water drill processing output. Therefore, the present application moves the installation position of the turntable machine position away from the rough grinding machine position, and extends the length of the needle row based on the original size of the needle row to reach the maximum allowable length of the rough grinding machine position.

[0077] It is worth noting that due to the limitation of the structure of the water rhinestone processing production line provided by the prior art, the needle row cannot be extended to the maximum allowable length, which is usually 900mm. This application moves the position of the turntable, thereby extending the needle row length to the maximum allowable length of 950mm without affecting the needle row driving time, and increasing the water rhinestone output by 1.06 times.

[0078] See also Figure 3 As shown, Figure 3 A schematic cross-sectional view of a gluing machine station (A), a powder applying machine station (B) and a material unloading machine station (C) provided in an embodiment of the present application.

[0079] Specifically, the gluing process refers to flattening the glue powder in the powder box, and after the needle bar is transferred to the gluing machine through the driving mechanism, the needle bar is controlled to feed toward the powder box, and the heated needle bar is brought into contact with the flattened glue powder, so that the glue powder adheres to the needle bar. Figure 3 A shows a cross-sectional schematic diagram of the gluing machine, which includes a frame, a powder box, a powder box flattening mechanism, a needle row driving mechanism, and a needle row track. The needle row track is shared by the running line on one side, and the needle row circulates on the needle row track. The powder box flattening mechanism is used to flatten the glue powder in the powder box, and the powder box flattening mechanism and the powder box are arranged on the frame. The needle row driving mechanism is arranged on the frame, and is used to drive the needle row that flows to the gluing machine to feed to the powder box, thereby completing the powdering operation.

[0080] The loading process refers to the material box containing the pearl embryos to be loaded. After the needle row is transferred to the loading position through the driving mechanism, the matching mechanism under the material box is controlled to feed toward the needle row. Through the cooperation between the matching mechanism and the needle row, the pearl embryos are loaded onto the needle row. Figure 3 B shows a cross-sectional schematic diagram of the loading station, which includes a frame, a material box, and a matching mechanism. The material box and the matching mechanism are arranged on the frame, the material box contains the bead embryos to be processed, and the matching mechanism is provided with a bayonet for matching with the needle row to engage the bead embryos. The matching mechanism is driven to feed in the direction of the needle row to complete the loading of the bead embryos.

[0081] The unloading process refers to the process in which the needle row is transferred to the unloading machine position through the driving mechanism, and the bead embryo brush set at the unloading machine position feeds the needle row, and the rotating bead embryo brush brushes the bead embryo on the needle row, causing it to fall into the receiving box. Figure 3C shows a cross-sectional schematic diagram of the unloading machine. It includes a frame, a receiving box, and a bead embryo brush. The receiving box and the bead embryo brush are arranged on the frame, and the bead embryo brush is driven to feed the needle row, brushing the bead embryo clamped by the needle row, so that it falls off the needle row and falls into the receiving box.

[0082] Since both the flushing process and the high-frequency heating process are performed on the moving needle row, it is only necessary to align the water outlet or the heating port with the working part of the needle row. Therefore, this application does not display its structure, and its structure can be understood by referring to other machine positions.

[0083] See also Figure 4 As shown, Figure 4 A schematic cross-sectional view of a rough grinding station (D) and a polishing station (E) provided in an embodiment of the present application.

[0084] Specifically, the grinding process refers to controlling the needle row to feed the rotating grinding wheel after the needle row is transferred to the rough grinding or fine grinding position through the driving mechanism, and grinding the multiple arranged bead embryos as a whole through the moving grinding wheel surface; the polishing process refers to controlling the needle row to feed the rotating polishing wheel after the needle row is transferred to the first polishing or second polishing position through the driving mechanism, and polishing the multiple arranged bead embryos as a whole through the moving polishing wheel surface. Among them, D1 refers to the grinding wheel diameter of the rough grinding position, D2 refers to the inner diameter of the polishing sleeve of the first polishing position, and D3 refers to the outer diameter of the polishing sleeve of the first polishing position, and the polishing sleeve is sleeved on the roller in a sleeved manner.

[0085] Furthermore, it can be seen from Table 1 that, without considering the common time of the needle row drive, the working time of each machine position of gluing, loading, turntable flushing, coarse grinding, fine grinding, first polishing, second polishing, heating and unloading is different. Since the rotation operation or rotation operation of the turntable position during the turntable flushing process is limited by the motor rotation speed and the stability of the mechanism, its working time is basically determined. In addition, the operations of gluing, loading, unloading, etc. only need to control the feeding operation, and the working time is less than the turntable position, so the turntable position can be used as a benchmark to determine the production rhythm. At this time, the coarse grinding machine position, fine grinding machine position, first polishing machine position and second polishing machine position become the bottleneck processes that restrict the production rhythm, resulting in the inability to further increase the output of water drill production.

[0086] Furthermore, the operation time of the rotary table is used as the beat benchmark of the processing line, and the preset benchmark beat R X =S Z +S A ; In order to ensure the time of the rough grinding machine Ry = S Z +y+t a ≤R X , that is, processing time y≤R X -S Z -ta=S A -t a .

[0087] Furthermore, π*D1*y*n1=N*L, then When D1 is greater than When the final production time of the rough grinding station is Ry≤R X , so that the bottleneck problem of the rough grinding machine can be solved, and its final production time is less than the time spent on the turntable machine, thereby making the production cycle of the device provided by the present application smaller and the water drill output higher.

[0088] N is the number of facets of the rhinestone, L is the processing length of any facet of the rhinestone, n1 is the grinding wheel speed, t a The minimum feed time allowed for the needle row, R X is the base beat, S Z S is the shortest time for the needle row to move from one position to the next. A The time required for the turntable to complete one rotation operation / slewing operation.

[0089] Specifically, the grinding efficiency of the bead embryo 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 embryo. Therefore, this application treats the grinding wheel speed as a constant and reduces the grinding working time by increasing the grinding wheel diameter, as shown in Table 2.

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

[0091] Grinding wheel diameter / mm 300 310 320 330 340 350 360 370 380 390 400 Working time / s 1.253 1.232 1.214 1.195 1.173 1.152 1.134 1.113 1.092 1.075 1.055

[0092] It can be seen from Table 2 that as the diameter of the grinding wheel continues to increase, the working time of the grinding wheel station continues to decrease.

[0093] Theoretically, when the diameter of the grinding wheel of the rough grinding machine is between 370-400mm, the working time of the grinding wheel can be matched with the working time of the turntable machine, thereby obtaining the best production cycle of 1.76s.

[0094] It is worth noting that the larger the diameter of the grinding wheel, the better. Although a larger grinding wheel diameter will provide a shorter working time, it will lead to a larger installation space required for the frame and increase the manufacturing cost of the mechanism. Therefore, it is appropriate to increase the grinding wheel diameter to ensure that the reduction in working time provided by the grinding wheel diameter can be aligned with the preset reference beat, and at the same time, the grinding wheel diameter is controlled within the acceptable range of the frame.

[0095] See also Figure 5 As shown, Figure 5 The embodiment of the present application provides a schematic diagram for adjusting the actual reference tempo.

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

[0097] Through step S1, according to the preset reference beat R X , preset the feeding speed of each machine position, so that the feeding time of the gluing machine position, loading 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, S7 respectively;

[0098] Then, in step S2, the actual processing time and actual yield rate of each machine position are collected in real time, which are S 1′ , S 2′ , S 3′ , S 4′ , S 5′ , S 6′ , S 7′ , and y1, y2, y3, y4, y5, y6, y7;

[0099] Then, in step S3, the actual reference beat R is obtained by taking the ratio of the inverse of the actual yield rate as the adjustment weight. X′ ,

[0100]

[0101] Finally, step S4 is performed according to the actual reference beat R X′ , and adjust the feed speed of each machine position in real time.

[0102] Furthermore, in the actual operation of the high-efficiency automatic water drill processing device provided by the present application, although the operation time of the rotary table position is used as the preset reference beat, the water drill processing output can be effectively improved. However, in actual operation, the actual processing time of each position is often different due to the error of the driving mechanism. At the same time, the working time of the position will affect the water drill yield of the position.

[0103] Therefore, the present application uses the water rhinestone yield rate of each machine position as the adjustment ratio, and adjusts the preset reference beat by measuring the actual processing time, so as to balance the water rhinestone output and the water rhinestone yield rate, which not only improves the water rhinestone output but also ensures the water rhinestone yield rate.

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

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

[0106] Furthermore, a polishing wheel of a polishing machine is provided with an outer diameter of D3 and an inner diameter of D2, wherein D3>D2>D1;

[0107]

[0108] n2 is the speed of the throwing wheel.

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

[0110] Please see Table 3 below for the relationship between the diameter of the casting wheel and the working time.

[0113] Furthermore, the present application provides a high-efficiency automatic water drill processing device, comprising: adjusting the grinding wheel speed according to the consumption i of the grinding abrasive,

[0114] 0≤i<D3-D2.

[0115] Specifically, when the abrasive is worn, the feeding time of the needle row will continue to increase. In order to compensate for the working time of the polishing machine, the rotation speed of the polishing wheel is appropriately adjusted to make the rotation speed faster.

[0116] Furthermore, the number of machine positions required for the polishing process is related to the polishing time required to complete all facets N of the rhinestone;

[0117] when When the aircraft is launched, three more landing positions will be added.

[0118] The polishing wheel speed n2 is determined according to the diamond polishing yield rate y5, y5≥50%.

[0119] Specifically, considering the polishing quality, the polishing wheel speed cannot be increased indefinitely, and should be guided by the water rhinestone polishing yield rate.

[0120] The present application is described in detail above. Specific examples are used in the present application to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
