Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The automatic grinding and dust removal integrated machine includes a cabinet 1, a grinding chamber 2 at the front end of the cabinet 1, a multi-axis grinding robot 3 inside the grinding chamber 2, and a workpiece placement rack 4 inside the grinding chamber 2. The multi-axis grinding robot 3 can realize the automatic grinding of the workpiece.

[0028] In some embodiments, the workpiece placement rack 4 is rotatable. For example, a motor mounting chamber 5 is provided below the grinding chamber 2, a rotary motor 6 is installed in the motor mounting chamber 5, and a bushing 7 extends upward to the grinding chamber 2 in the motor mounting chamber 5. A rotary shaft 8 is rotatably connected to the bushing 7. The upper end of the rotary shaft 8 is located in the grinding chamber 2 and is connected to the workpiece placement rack 4. The lower end of the rotary shaft 8 is located in the motor mounting chamber 5 and is powered to the rotary output shaft of the rotary motor 6 through a pulley and a drive belt, so that the rotary motor 6 can drive the workpiece placement rack 4 to rotate, so that the workpiece to be ground placed on the workpiece placement rack 4 can be better adapted to the multi-axis grinding robot 3 for grinding operations.

[0029] In some embodiments, the multi-axis grinding robot 3 is, for example, a five-axis robot, with a grinding head connected to the end axis.

[0030] In this embodiment, a first filter chamber 9 is provided behind the grinding chamber 2, and a second filter chamber 10 is provided to the right of the first filter chamber 9.

[0031] The grinding chamber 2 is provided with a gas inlet 11. The bottom of the grinding chamber 2 is connected to the bottom of the first filter chamber 9, and the top of the first filter chamber 9 is connected to the top of the second filter chamber 10. The second filter chamber 10 is provided with a gas outlet 12, thus forming a gas flow path from the gas inlet 11 to the grinding chamber 2, the first filter chamber 9, the second filter chamber 10, and the gas outlet 12.

[0032] In this embodiment, a negative pressure device is provided on the cabinet 1. The negative pressure device includes an exhaust fan 13 installed on the cabinet 1 and corresponding to the gas outlet 12. The exhaust port of the exhaust fan 13 corresponds to the gas outlet 12. When the exhaust fan 13 is drawing air, the second filter chamber 10 is formed with negative pressure, so that the above-mentioned gas flow path is formed into a forced gas flow path driven by negative pressure, so that the exhaust gas generated by grinding can be driven by negative pressure to the first filter chamber 9 and the second filter chamber 10, and discharged from the gas outlet 12 after passing through the first filter chamber 9 and the second filter chamber 10.

[0033] In some embodiments, the outlet gas of the exhaust fan 13 is connected to a three-way connector 14 (such as a three-way pipe), and one of the ports of the three-way connector 14 is connected to the grinding chamber 2 through a gas circulation pipe 15. After the exhaust fan 13 draws gas out of the second filter chamber 10, a portion of the gas can be discharged through the other port of the three-way connector 14, while the other portion of the gas can continue to flow back to the grinding chamber 2 through the gas circulation pipe 15 for recycling and filtration.

[0034] In this embodiment, a first water curtain generator 16 is installed inside the first filter chamber 9. The water curtain generated by the first water curtain generator 16 is located inside the first filter chamber 9 and at the point along which the gas flows through the first filter chamber along the forced gas flow path. That is, the water curtain generated by the first water curtain generator 16 is positioned in the forced gas flow path, and the gas needs to pass through the water curtain generated by the first water curtain generator 16 to pass through the first filter chamber 9. During this process, the water curtain generated by the first water curtain generator 16 filters the grinding dust from the grinding exhaust gas, making the gas entering the second filter chamber 10 cleaner.

[0035] In some embodiments, a plurality of first guide plates 17 are further provided in the first filter chamber 9, and the plurality of first guide plates 17 are configured to cause at least one forward and backward reversal during the flow of gas from the bottom to the top of the first filter chamber 9.

[0036] like Figure 4 , 5 As shown, the multiple first guide plates 17 are arranged vertically spaced and staggered front to back.

[0037] In some embodiments, the first water curtain generating device 16 includes a first water injection container 161 installed in the first filter chamber 9, and a first water supply pipe 162 for supplying water to the first water injection container 161. The first water injection container 161 has a first overflow port 163, and the water in the first water injection container 161 overflows from the first overflow port 163 and flows down to form a water curtain.

[0038] In some embodiments, the first water injection container 161 extends to the left and right, and the first overflow outlet extends to the left and right or has a plurality of first overflow outlets spaced apart to the left and right.

[0039] In some embodiments, the water curtain generated by the first water curtain generator 16 is located at one of the front-to-back reversal positions formed by multiple first guide plates 17. On the one hand, when the first overflow outlet is arranged to extend left and right or when multiple first overflow outlets are arranged to be spaced left and right, making the water curtain extend left and right, the aforementioned front-to-back gas guidance allows the gas to be smoothly guided to pass through the water curtain, and the water curtain being located at the front-to-back reversal position allows the gas to undergo cyclonic centrifugation after passing through the water curtain, that is, the grinding dust that has increased in weight due to moisture after passing through the water curtain will be centrifuged and separated in the connecting centrifugation, so that the grinding gas can be better filtered when passing through the first filter chamber 9.

[0040] In this embodiment, a second water curtain generator 18 is also provided on the cabinet 1. The water curtain generated by the second water curtain generator 18 is located at the connection between the first filter chamber 9 and the grinding chamber 2, so that when the grinding exhaust gas enters the first filter chamber 9 from the grinding chamber 2, the grinding dust can be filtered by the water curtain generated by the second water curtain generator 18, making the gas entering the first filter chamber 9 cleaner; and the second water curtain generator 18 can form a double water curtain filtration with the first water curtain generator 16.

[0041] Preferably, the second water curtain generating device 18 is installed at the top of the rear inner wall of the polishing chamber 2, and the water flowing out of the second water curtain generating device 18 to form the water curtain flows from top to bottom along the rear inner wall of the polishing chamber 2, and finally falls at the bottom of the rear inner wall of the polishing chamber 2 (corresponding to the connection between the first filter chamber and the polishing chamber) to form the water curtain.

[0042] The second water curtain generating device 18 is designed so that in addition to the water curtain being formed at the connection between the first filter chamber 9 and the grinding chamber 2, a water film can also be formed on the rear inner wall of the grinding chamber 2. This allows for better filtration of grinding dust during the grinding operation, where dust is splashed. Specifically, when the splashed grinding dust lands on the rear inner wall of the grinding chamber 2, it comes into contact with the water film and is adsorbed and carried down, thus improving the overall adsorption and filtration capacity.

[0043] In some embodiments, the second water curtain generating device 18 includes a second water injection container 181 installed on the top of the rear inner wall of the grinding chamber 2, and a second water supply pipe 182 for supplying water to the second water injection container 181. The second water injection container 181 has a second overflow port 183. Water in the second water injection container 181 overflows from the second overflow port 183 and flows down the rear inner wall of the grinding chamber 2, eventually falling at the bottom of the rear inner wall of the grinding chamber 2 to form a water curtain.

[0044] In some embodiments, the second water inlet container 181 extends to the left and right, and the second overflow outlet extends to the left and right or has a plurality of second overflow outlets spaced apart to the left and right.

[0045] In this embodiment, a dry filtration device is provided in the second filtration chamber 10. The dry filtration device is configured to filter the gas as it passes through the second filtration chamber 10.

[0046] In this embodiment, the dry filtration device includes at least one dry filter screen 19 disposed on the forced gas flow path.

[0047] In some embodiments, the cabinet 1 is provided with a maintenance door 20 corresponding to the second filter chamber 10, through which the dry filter device can be maintained.

[0048] In this embodiment, a water collection chamber 21 is provided inside the cabinet 1, located below the first filter chamber 9. The water collection chamber 21 is connected to the first filter chamber 9 and the polishing chamber 2. The water collection chamber 21 is used to collect the water body after the first water curtain generating device 16 and the second water curtain generating device 18 generate the water curtain.

[0049] The cabinet 1 is equipped with a water guide plate 22 located at the bottom of the first filter chamber 9. The water guide plate 22 extends forward and downward from the connection between the first filter chamber 9 and the grinding chamber 2 to the bottom of the grinding chamber 2. A filter screen 23 is connected to the front end of the water guide plate 22. The water used to generate the water curtain flows down to the water guide plate 22 and flows forward along the water guide plate 22 to be filtered by the filter screen 23, and then flows to the water collection chamber 21.

[0050] In some embodiments, a circulating water supply device 24 is installed on the cabinet 1. The circulating water supply device 24 supplies water in the water collection chamber 21 to the first water supply pipe 162 of the first water curtain generator 16 and the second water supply pipe 182 of the second water curtain generator 18, so as to form a water recycling system.

[0051] In some embodiments, the circulating water supply device 24 includes, for example, a water pump and corresponding piping installed on the counter 1.

[0052] In this embodiment, the cabinet 1 is provided with an operating door 25 corresponding to the grinding chamber 2. The grinding chamber can be opened through the operating door 25 to facilitate workpiece replacement, for example.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
