Description

Technical Field

[0001] The invention relates to the technical field of deburring and cleaning equipment, in particular to a high-pressure water-sand automatic deburring equipment. Background Art

[0002] In the production of electronic product casings, especially 3C products like mobile phone cases, the combination of metal casings and injection molding is widely used. To ensure the product's signal transmission performance and insulation, glass fiber is often added to the plastic material used in the injection molding process to enhance its strength. However, during processing, the high hardness of glass fiber can easily cause tool wear and material tear during cutting. Furthermore, carbide cutting tools wear quickly, blunting their edges, and improper geometric parameters can affect cutting performance. Furthermore, improper cutting speeds, feed rates, and cutting depths can cause material deformation or tearing. These combined factors can easily lead to numerous burrs on the finished workpiece surface.

[0003] For products such as mobile phone cases and tablet cases, their internal structures are complex, and there are some parts with relatively narrow angles and positions. These special structures make it extremely difficult to remove burrs, resulting in a low yield rate for burr removal. In order to ensure product quality, companies often need to invest a lot of manpower in manual deburring operations. In the existing technology, tunnel, rotary and dry ice deburring technologies are usually used to deal with it. However, tunnel deburring equipment is bulky and energy-intensive, and is not effective in removing burrs from complex-shaped shells; rotary deburring causes great damage to the workpiece surface and can easily lead to product appearance defects; dry ice deburring is costly and has a certain impact on the environment. Therefore, how to effectively solve the generation of burrs during the processing process and improve the efficiency and yield of burr removal has become a technical problem that needs to be urgently solved in the current field of electronic product shell production. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a high-pressure water sand automatic deburring device that can remove burrs efficiently.

[0005] In order to solve the above technical problems, the present invention adopts a technical solution: providing a high-pressure water-sand automatic deburring device, comprising a transmission line, a high-pressure water deburring mechanism, a water-sand deburring mechanism and a cleaning mechanism arranged in sequence along the conveying direction of the transmission line; the transmission line is used to sequentially transmit the workpiece to be cleaned to the high-pressure water deburring mechanism, the water-sand deburring mechanism and the cleaning mechanism, so that the high-pressure water deburring mechanism performs rough deburring on the workpiece, the water-sand deburring mechanism performs fine deburring on the workpiece, and the cleaning mechanism removes the water-sand remaining on the surface of the workpiece.

[0006] Furthermore, the high-pressure water deburring mechanism and the water-sand deburring mechanism are both arranged outside the lateral side of the transmission line; the high-pressure water deburring mechanism and the water-sand deburring mechanism are both arranged on a three-axis module. The high-pressure water deburring mechanism and the water-sand deburring mechanism both include a spray head assembly and a picking assembly connected to the three-axis module. When the transmission line transports the workpiece to the high-pressure water deburring mechanism or the water-sand deburring mechanism, the corresponding picking assembly picks up the workpiece to the high-pressure water deburring mechanism or transports it to the water-sand deburring mechanism, and the corresponding spray head assembly performs rough deburring or fine deburring on the workpiece.

[0007] Furthermore, the three-axis module includes an X-axis moving unit, a Y-axis moving unit, a first Z-axis moving unit and a second Z-axis moving unit connected to the X-axis moving unit or the Y-axis moving unit. The spray head assembly is arranged at the output end of the first Z-axis moving unit, and the picking assembly is arranged at the output end of the second Z-axis moving unit.

[0008] Furthermore, the first Z-axis moving unit and the second Z-axis moving unit are connected to the X-axis moving unit or the Y-axis moving unit through a first fixing seat.

[0009] Furthermore, the second Z-axis moving unit is arranged on the first Z-axis moving unit through a second fixing seat.

[0010] Furthermore, multi-angle control mechanisms are arranged at both the high-pressure water deburring mechanism and the water-sand deburring mechanism. The workpiece is fixed at the multi-angle control mechanism so that each burr area of the workpiece can face the spray head assembly under the control of the multi-angle control mechanism.

[0011] Furthermore, it further includes a workpiece carrier. The multi-angle control mechanism is provided with a fixing component for fixing the workpiece carrier. The workpiece is fixed on the workpiece carrier, and the transmission line is used to sequentially transport the workpiece carrier loaded with the workpiece to the high-pressure water deburring mechanism, the water-sand deburring mechanism, and the cleaning mechanism.

[0012] Furthermore, the cleaning mechanism includes a third spray head and a centrifugal pump. The third spray head is arranged on the conveyor belt to clean the workpiece transported by the conveyor belt. The water inlet end of the centrifugal pump is connected to a water source, and the water outlet end is communicated with the third spray head.

[0013] Further, the nozzle assembly includes a plurality of nozzles. Each nozzle includes a cavity and a nozzle. An inlet channel, an outlet channel communicating with the nozzle, and a passage are formed on the cavity. The inner end of the passage communicates with the outlet channel, and the outer end penetrates the nozzle outward; the passage of the nozzle belonging to the high-pressure water deburring mechanism is used for air to enter the cavity to form cavitation bubble water with the water source, and the passage of the nozzle belonging to the water-sand deburring mechanism is used for sand grains to enter the cavity to form a water-sand mixture with the high-pressure water.

[0014] Further, it further includes a water-sand recovery mechanism disposed below the high-pressure water deburring mechanism and the water-sand deburring mechanism. The water-sand recovery mechanism is used to filter burrs and sand grains in sequence, convey the filtered water to the high-pressure water deburring mechanism, and convey the filtered sand grains to the water-sand deburring mechanism.

[0015] The high-pressure water-sand automatic deburring equipment of the present invention has at least the following beneficial effects: First, the equipment uses the high-pressure water deburring mechanism to perform rough deburring, and then uses the water-sand deburring mechanism to perform fine deburring. Combined with the multi-angle control mechanism, it can comprehensively and without dead angles remove the burrs on the surface of the workpiece, effectively improving the quality and efficiency of deburring. Second, the equipment realizes automated production. The transmission line sequentially conveys the workpieces to each deburring and cleaning mechanism, reducing manual intervention and improving production efficiency. At the same time, the equipment adopts the high-precision positioning and modular design of the three-axis module, which not only enhances the flexibility and accuracy of operation, but also facilitates maintenance and upgrade, further improving the stability and reliability of the equipment. In addition, the equipment is equipped with a water-sand recovery mechanism, which can filter and recycle burrs, water and sand grains, realize the recycling of resources, reduce production costs, and reduce the impact on the environment. The high-pressure water flushing and high-pressure air drying functions of the cleaning mechanism ensure the cleanliness of the workpiece surface and further improve the product quality. The equipment is applicable to workpieces of various shapes and sizes, especially parts with complex internal structures, narrow angles and positions, and has wide applicability. In summary, the high-pressure water-sand automatic deburring equipment significantly improves the efficiency and quality of deburring, reduces production costs, improves production efficiency, and has high practicability and market competitiveness through its characteristics of high efficiency, automation, resource recycling and high-precision control.

[0042] The present invention will be further described below with reference to the accompanying drawings.

[0043] Please refer to Figure 1 and Figure 2 As shown in and, the high-pressure water and sand automatic deburring equipment of the present invention includes a transmission line 2, a high-pressure water deburring mechanism 3, a water and sand deburring mechanism 4, and a cleaning mechanism 5 that are sequentially arranged along the conveying direction of the transmission line 2. The transmission line 2 is used to sequentially convey the workpiece to be cleaned to the high-pressure water deburring mechanism 3, the water and sand deburring mechanism 4, and the cleaning mechanism 5, so that the high-pressure water deburring mechanism 3 performs rough deburring on the workpiece, the water and sand deburring mechanism 4 performs fine deburring on the workpiece, and the cleaning mechanism 5 removes the water and sand remaining on the surface of the workpiece.

[0044] The high-pressure water and sand automatic deburring equipment further includes a cabinet 1. The transmission line 2 is a conveyor belt, and the transmission line 2 horizontally passes through the cabinet 1, and both ends of the transmission line 2 are exposed outside the cabinet 1 for the user to load and unload materials. Adjacent first working area 11 and second working area 12 are arranged on the cabinet 1 along the conveying direction of the transmission line 2, and both the first working area 11 and the second working area 12 are located outside the lateral side of the transmission line 2. The high-pressure water deburring mechanism 3 is arranged in the first working area 11, and the water and sand deburring mechanism 4 is arranged in the second working area 12.

[0045] Please refer to Figure 3, the high-pressure water deburring mechanism 3 includes a first nozzle assembly 31, a first picking assembly 32, and a first multi-angle control mechanism 33 for driving the workpiece to rotate so that each burr area of the workpiece can face the first nozzle assembly 31. It also includes a workpiece carrier 34 used in cooperation with the first multi-angle control mechanism 33. The first picking assembly 32 is used to pick up the workpiece on the transfer line 2 and place it on the first multi-angle control mechanism 33, and the first nozzle assembly 31 is used to spray high-pressure water on the workpiece to remove burrs.

[0046] Please refer to Figure 4 , specifically, the workpiece carrier 34 includes a first plate 341 and a second plate 342. The first plate 341 is hinged to one side of the second plate 342 so that they can flip relative to each other. The first plate 341 and the second plate 342 can clamp the workpiece between them. A plurality of through windows 343 are provided on both the first plate 341 and the second plate 342, so that high-pressure water and water-sand mixture can pass through the windows 343 and shoot at the workpiece to remove the burrs on the workpiece. The first multi-angle control mechanism 33 is a motor, and the output shaft of the motor is connected to a fixing component 35 for fixing the workpiece carrier 34. The fixing component 35 includes a support plate 351 for placing the workpiece carrier 34. The fixing component 35 also includes a first cylinder 352, a first pushing block 353, and a resisting block 354. The resisting block 354 is arranged at the edge of the upper end surface of the support plate 351 along the length direction of the support plate 351. The first cylinder 352 is fixedly arranged at the edge of the support plate 351 away from the resisting block 354, and the output shaft of the first cylinder 352 extends towards the middle of the support plate 351. The first pushing block 353 is fixedly connected to the output shaft of the first cylinder 352. When the workpiece carrier 34 is placed on the support plate 351, one side of the workpiece carrier 34 contacts the resisting block 354, and the other side is tightened by the cooperation of the first cylinder 352 and the first pushing block 353. With the cooperation of the first pushing block 353 and the resisting block 354, the workpiece carrier 34 is fixed.

[0047] The first picking assembly 32 includes a U-shaped plate 321, and second cylinders 322 and second pushing blocks 323 provided at two end feet of the U-shaped plate 321. The second cylinders 322 are fixedly arranged on each end foot of the U-shaped plate 321, and the output shafts of the second cylinders 322 extend towards the other second cylinder 322. The second pushing blocks 323 are fixedly arranged on the output shafts of the corresponding second cylinders 322. When the two second cylinders 322 work, the two second pushing blocks 323 move towards or away from each other to clamp or release the workpiece carrier 34.

[0048] Please refer to Figure 5 andFigure 6 The first nozzle assembly 31 includes a first high-pressure pump, a first plate 311, and a plurality of first nozzles 312 disposed on the first plate 311. The first high-pressure pump is capable of pumping water to the plurality of first nozzles 312 through the first plate 311. Each of the first nozzles 312 includes a first cavity 3121 and a first nozzle 3122. The first cavity 3121 is formed with a first water inlet channel 3123, a first water outlet channel 3124 communicating with the first nozzle 3122, and an air inlet channel 3125 communicating with the first water outlet channel 3124. When deburring, the first nozzle 3122 is positioned 25 mm from the workpiece. Pressurized water at 20-30 MPA enters the first cavity 3121 through the first water inlet channel 3123, which has an inner diameter of 1 mm. This creates a strong negative pressure within the first cavity 3121. Under the influence of this negative pressure, air enters the first cavity 3121 through the air inlet channel 3125. The air dissolves in the water, forming bubbles, which then enter the first nozzle 3122 along with the pressurized water to form cavitation bubble water. The cavitation bubble water contracts and squeezes again as it passes through the first nozzle 3122, gaining greater kinetic energy. When contacting a large burr, the cavitation bubbles collapse, releasing a shock wave that shatters the burr. The entire process lasts 20 seconds, achieving highly efficient burr removal.

[0049] The water-sand deburring mechanism 4 includes a second nozzle assembly 41, a second pickup assembly 42, and a second multi-angle control mechanism for rotating the workpiece so that each burred area of the workpiece is directed toward the second nozzle assembly 41. The second pickup assembly 42 has the same structure as the first pickup assembly 32, and the second multi-angle control mechanism has the same structure as the first multi-angle control mechanism 33. Both utilize the same workpiece carrier 34 as described above, so detailed descriptions are omitted here.

[0050] Please refer to Figure 7 and Figure 8, different from the high-pressure water deburring mechanism 3, the second nozzle assembly 41 includes a second high-pressure pump, a second flat plate 411, and a plurality of second nozzles 412 disposed on the second flat plate 411. The second high-pressure pump can pump the water-sand mixture to the plurality of second nozzles 412 through the second flat plate 411. Each of the second nozzles 412 includes a second cavity 4121 and a second nozzle 4122. A second water inlet channel 4123, a second water outlet channel 4124 communicating with the second nozzle 4122, and a sand inlet channel 4125 communicating with the second water outlet channel 4124 are formed on the second cavity 4121. The other end of the sand inlet channel 4125 is communicated with the conveying pipe 77. When deburring, the second nozzle 4122 is 25 millimeters away from the workpiece. The pressurized water source of 20-30 MPA enters the second cavity 4121 through the second water inlet channel 4123 with an inner diameter of 1 millimeter and forms a strong negative pressure inside the second cavity 4121. Under the influence of the negative pressure, the plastic sand grains with a diameter of 0.2 millimeters enter the second cavity 4121 through the sand inlet channel 4125 and enter the second nozzle 4122 together with the pressurized water source to form a water-sand mixture. When the water-sand mixture passes through the second nozzle 4122, it is further contracted and extruded to obtain greater kinetic energy. After the large burrs are processed by the first nozzle assembly 31, only fluff burrs remain. When the water-sand mixture contacts the fluff burrs, the fibrous and fluffy small fluff is cut off through the micro-cutting and fatigue fracture mechanism of the burrs, achieving the effect of precise deburring. The whole process lasts for 20 seconds.

[0051] The high-pressure water deburring mechanism 3 and the water-sand deburring mechanism 4 are both arranged on the three-axis module 6. The three-axis module 6 includes an X-axis moving unit, a Y-axis moving unit, a first Z-axis moving unit and a second Z-axis moving unit connected to the X-axis moving unit or the Y-axis moving unit. The Y-axis moving unit is the first electric slide rail 61, and there are two first electric slide rails 61 corresponding to the high-pressure water deburring mechanism 3 and the water-sand deburring mechanism 4 respectively. The two first electric slide rails 61 are respectively arranged on the two opposite wall surfaces of the first working area 11 and the second working area 12. The X-axis moving unit is the second electric slide rail 62, and the two ends of the second electric slide rail 62 are respectively slidably connected to the two first electric slide rails 61. The first Z-axis moving unit is the third electric slide rail 63 and the number of the third electric slide rails 63 is two. The two third electric slide rails 63 are respectively slidably connected to the second electric slide rail 62 through a first fixing seat 64. The two third electric slide rails 63 are respectively located in the first working area 11 and the second working area 12. Second fixing seats 65 are slidably arranged on the two third electric slide rails 63. The second Z-axis moving unit is the fourth electric slide rail 66 and the number of the fourth electric slide rails 66 is two. The two fourth electric slide rails 66 are respectively installed on the two second fixing seats 65. The first spray head assembly 31 and the second spray head assembly 41 are respectively arranged on the two second fixing seats 65, and the first picking-up assembly 32 and the second picking-up assembly 42 are respectively slidably arranged on the two fourth electric slide rails 66. Taking the high-pressure water deburring mechanism 3 as an example, when the second fixing seat 65 vertically slides on the third electric slide rail 63, the fourth slide rail and the first spray head assembly 31 both move vertically. At this time, the first spray head assembly 31 and the first picking-up assembly 32 move synchronously; on this basis, the first picking-up assembly 32 can also move vertically independently on the fourth electric slide rail 66. The advantage of such a setting is that the device can achieve high-precision three-dimensional positioning, ensuring that the spray head assembly and the picking-up assembly can accurately reach the required positions, thereby improving the precision and quality of deburring. In addition, the design of independent movement enables the first picking-up assembly 32 and the second picking-up assembly 42 to move vertically independently on the fourth electric slide rail 66, further enhancing the flexibility of the device. At the same time, this design also improves the stability and reliability of the device, reduces mechanical errors, and ensures the stable performance of the device during long-term operation. The modular design makes the maintenance and adjustment of the device more convenient, and is easy to upgrade and expand functions. To sum up, the structural design of this three-axis module 6 significantly improves the production efficiency and product quality through the advantages of high-precision positioning, flexibility, versatility, high efficiency, stability and reliability, etc.

[0052] The cleaning mechanism 5 includes a third spray head 51, a high-pressure blower, and a centrifugal pump. A vertical frame 52 is spanned across the conveyor belt in the width direction. The number of the vertical frames 52 is two, and the two vertical frames 52 are arranged at intervals along the conveying direction of the conveyor belt. The two third spray heads 51 are respectively arranged on the two vertical frames 52, and the spray nozzles of the third spray heads 51 face the direction of the conveyor belt. The third spray head 51 closer to the starting point of the conveyor belt is connected to the centrifugal pump to spray water on the workpiece, and the third spray head 51 closer to the end point of the conveyor belt is connected to the high-pressure blower to spray high-pressure air on the workpiece.

[0053] Please refer to Figures 9 to 15 , the high-pressure water and sand automatic deburring device further includes a water and sand recovery mechanism 7 disposed below the high-pressure water deburring mechanism 3 and the water and sand deburring mechanism 4. The water and sand recovery mechanism 7 is used to filter burrs and sand grains in sequence, and convey the filtered water to the high-pressure water deburring mechanism 3, and convey the filtered sand grains to the water and sand deburring mechanism 4. Specifically, the water and sand recovery mechanism 7 includes a water tank 71 and a water and sand mixing tank 72 that are interconnected. The burrs, water, and sand grain mixture flowing down from the high-pressure water deburring mechanism 3, the water and sand deburring mechanism 4, and the cleaning mechanism 5 are separated from each other after flowing into the water and sand recovery mechanism 7. The water enters the water tank 71 and is supplied to the high-pressure water deburring mechanism 3 and the water and sand deburring mechanism 4, and the sand grains are supplied to the water and sand deburring mechanism 4.

A ring groove 7434 is formed on one side of the top frame 7432 facing the bottom frame 7431. A plurality of through holes are formed through the drum 741. The drum 741 is clamped on the outer periphery of the frame 743, and the inner diameter of the ring groove 7434 matches the outer diameter of the drum 741 for the drum 741 to be clamped therein. The second filter screen 742 is clamped at a position between the drum 741 and the frame 743. Screw holes are formed on both the top frame 7432 and the bottom frame 7431, and a bolt 7435 is screwed into each screw hole. Rotating the bolt 7435 can make it press against the drum 741, making the connection between the drum 741 and the frame 743 more stable.

[0056] A support 75 and a driving mechanism 76 for driving the rotation of the drum 741 are further arranged in the water-sand mixing tank 72. The support 75 includes a bottom plate 751, a first side plate 752, and a second side plate 753. The bottom plate 751 is horizontally arranged at the bottom of the water tank 71, and the first side plate 752 and the second side plate 753 are vertically arranged at both ends of the bottom plate 751 respectively. The driving mechanism 76 is arranged on the first side plate 752, the filter hopper 731 is arranged on the second side plate 753, and the drum 741 is inclined from top to bottom from near the filter hopper 731 to far from the filter hopper 731.

[0060] The automatic deburring equipment of high-pressure water and sand of the present invention further includes a control panel 8, and the control panel 8 is in signal connection with the transmission line 2, the first multi-angle control mechanism 33, the first cylinder 352, the second cylinder 322, the first high-pressure pump, the second multi-angle control mechanism, the second high-pressure pump, the first electric slide rail 61, the second electric slide rail 62, the third electric slide rail 63, the fourth electric slide rail 66, the centrifugal pump, the high-pressure blower, the third cylinder 761 and the water pump. Thus, the user can control the working states of the above equipment through the control panel 8.

[0061] The working mode of one embodiment of the automatic deburring equipment of high-pressure water and sand of the present invention is as follows: During use, the workpiece is fixed in the workpiece carrier 34, and the workpiece carrier 34 with the workpiece fixed is placed on the transmission line 2. When the workpiece carrier 34 passes through the first working area 11, the first picking component 32 picks up the workpiece carrier 34 and places it on the pallet 351, and the fixing component 35 fixes the workpiece carrier 34. At this time, several first nozzles 312 spray high-pressure water on the workpiece carrier 34 to roughly remove burrs. During the deburring process, the first multi-angle control mechanism 33 drives the pallet 351 to rotate to adjust the angle of the workpiece carrier 34, so as to make the deburring more thorough without dead angles. After the rough deburring is completed, the first picking component 32 places the workpiece carrier 34 on the transmission line 2 again, and the transmission line 2 continues to transport the workpiece carrier 34 to the second working area 12.

[0062] When the workpiece carrier 34 passes through the second working area 12, the working modes of the second picking component 42 and the second multi-angle control mechanism and other components are the same as those of the first picking component 32 and the first multi-angle control mechanism 33. Several second nozzles 412 spray a water-sand mixture on the workpiece carrier 34 to finely remove burrs. After the fine deburring is completed, the second picking component 42 places the workpiece carrier 34 on the transmission line 2 again, and the transmission line 2 continues to transport the workpiece carrier 34 to the cleaning mechanism.

[0063] Two third nozzles 51 in the cleaning mechanism spray high-pressure water and high-pressure air respectively. First, the workpiece carrier 34 and the workpiece clamped in the workpiece carrier 34 are rinsed with high-pressure water, and then they are further cleaned with high-pressure air to remove all the residual debris or water on their surfaces. Thus, one-time burr removal is completed.

[0064] During the burr removal process, the mixture of burrs, water, and sand grains generated falls downward into the filter hopper 731. The burrs are filtered by the first filter screen 732 and remain in the filter hopper 731, while the water-sand mixture flows into the drum 741 through the lower port of the filter hopper 731. The water flows out through the second filter screen 742 and several through-holes into the water-sand mixing box 72, and the sand grains remain in the drum 741. The water remaining in the water-sand mixing box 72 enters the water tank 71. After being filtered layer by layer through the third filter screen 712, the water is transported to the first water inlet channel 3123, the second water inlet channel 4123, and the third spray head 51. The sand grains remaining in the drum 741 enter the sand inlet channel 4125 through the delivery pipe 77 for recycling.

[0065] Compared with the prior art, the high-pressure water-sand automatic burr removal equipment of the present invention has the following advantages. Firstly, the equipment performs rough burr removal through the high-pressure water burr removal mechanism and then fine burr removal through the water-sand burr removal mechanism. Combined with the multi-angle control mechanism, it can comprehensively and without dead angles remove the burrs on the surface of the workpiece, effectively improving the quality and efficiency of burr removal. Secondly, the equipment realizes automated production. The transmission line sequentially transports the workpieces to each burr removal and cleaning mechanism, reducing manual intervention and improving production efficiency. At the same time, the equipment adopts the high-precision positioning and modular design of the three-axis module, which not only enhances the flexibility and accuracy of operation but also facilitates maintenance and upgrading, further improving the stability and reliability of the equipment. In addition, the equipment is equipped with a water-sand recycling mechanism, which can filter and recycle burrs, water, and sand grains, realizing the recycling of resources, reducing production costs, and minimizing the impact on the environment. The high-pressure water flushing and high-pressure air drying functions of the cleaning mechanism ensure the cleanliness of the workpiece surface and further improve the product quality. The equipment is applicable to workpieces of various shapes and sizes, especially for parts with complex internal structures, narrow angles, and positions, and has wide applicability. In summary, the high-pressure water-sand automatic burr removal equipment significantly improves the efficiency and quality of burr removal, reduces production costs, and increases production efficiency through its characteristics of high efficiency, automation, resource recycling, and high-precision control, and has high practicality and market competitiveness.
