Description

Technical Field

[0001] This application relates to the technical field of die casting production, and in particular to a rapid surface treatment device and method for die castings. Background Technology

[0002] Die casting technology is widely used in the casting of non-ferrous metals in aerospace, automotive, and high-speed rail industries to produce metal parts with complex shapes and precise dimensions. With industrial development, the requirements for the surface quality of die castings are becoming increasingly stringent. However, defects such as porosity, cracks, and burrs often appear on the surface of die castings due to mold wear, mold release agent residue, and other reasons. These defects not only result in insufficient surface roughness but also reduce the mechanical properties and service life of the parts.

[0003] Common surface treatment methods for die-cast parts include manual grinding, mechanical polishing, chemical polishing, and laser treatment. These methods achieve the required surface roughness, improving the mechanical properties and lifespan of the parts. Manual grinding offers high flexibility but is inefficient; mechanical polishing is highly efficient but may cause secondary deformation; chemical polishing provides uniform treatment but pollutes the environment; and laser treatment offers high precision but requires expensive equipment. Each method has its advantages and disadvantages, making it difficult to simultaneously balance efficiency, cost, and environmental requirements.

[0004] Existing technologies suffer from problems such as low processing efficiency, high cost, and significant environmental pollution, failing to meet the requirements of modern manufacturing for efficient, high-quality, environmentally friendly, and low-cost surface treatment of die-cast parts. Summary of the Invention

[0005] To meet the requirements of modern manufacturing for efficient, shift-based, and low-cost surface treatment of die-cast parts, this application provides a rapid surface treatment device and method for die-cast parts.

[0006] Firstly, this application provides a rapid surface treatment device for die-cast parts, which adopts the following technical solution: A rapid surface treatment device for die-cast parts includes a machine body, a conveyor belt, and a sandblasting mechanism. The conveyor belt is used to transport multiple die-cast parts and to create a certain distance between adjacent die-cast parts. The sandblasting mechanism includes: The movable block is slidably mounted on the machine body and positioned above the conveyor belt along the direction of conveyor belt movement; The push component is used to drive the movement of the moving block; Cover body one and cover body two are spaced apart along the sliding direction of the moving block and are vertically slidable on the moving block. The conveyor belt drives the die-casting part to pass through cover body one and cover body two in sequence. The lifting assembly is used to drive the vertical movement of the first and second housings; The cleaning and sandblasting components are connected to the interior of cover one and cover two, respectively; The detection component is installed on the second cover and is used to detect the surface roughness of the die-casting parts and is electrically connected to the sandblasting component. The lifting assembly drives the first and second covers to move downwards and press against the conveyor belt, causing two adjacent die-cast parts to move into the first and second covers. The first and second covers move simultaneously with multiple die-cast parts. The cleaning assembly starts to clean the surface of the die-cast parts and collects the impurities after cleaning. The sandblasting assembly performs sandblasting treatment on the surface of the die-cast parts according to the detection data of the detection assembly and collects the sand after treatment. The detection assembly is used to detect the surface roughness of the die-cast parts after sandblasting. After the cleaning and sandblasting assemblies complete their processing, the first and second covers move upwards and then back to their original positions.

[0007] By adopting the above technical solution, a conveyor belt drives multiple die-cast parts to move, with a certain distance between adjacent die-cast parts. When two die-cast parts move to below cover one and cover two, the lifting assembly is activated to drive cover one and cover two to move down and press against the conveyor belt, so that the two adjacent die-cast parts move into cover one and cover two respectively. The die-cast parts, cover one, and cover two move simultaneously. The cleaning assembly is activated to clean the die-cast parts in cover one and collect the impurities after cleaning. The detection assembly first detects the surface roughness of the die-cast parts. Based on the measured values, the sandblasting assembly performs sandblasting and polishing on the surface of the die-cast part located inside the second housing. During the process, the sand that escapes into the second housing is collected. The cleaning assembly stops after cleaning is completed. The sandblasting assembly pauses after running for a period of time, and the testing assembly continues to test the surface roughness of the die-cast part. If the surface roughness of the die-cast part meets the standard, the sandblasting assembly stops. If the surface quality of the die-cast part does not meet the standard, the sandblasting assembly continues to run until the surface quality of the die-cast part meets the standard. The first and second housings then move upwards and then back to their original positions.

[0008] The conveyor belt drives the next two die-cast parts to continue the above processing steps inside housing one and housing two. The cleaned die-cast parts are then moved to housing two for sandblasting. After the die-cast parts are cleaned, they are inspected by the detection component, which improves the accuracy of the inspection. This allows the sandblasting component to accurately calculate parameters such as the amount and intensity of sandblasting, improving the sandblasting and polishing effect and efficiency. Furthermore, since the cleaning and sandblasting are carried out inside housing one and housing two, the risk of impurities and sand escaping into the external environment is reduced, thus achieving the requirements of high efficiency, high quality, environmental protection, and low cost.

[0009] Optionally, the first and second covers are provided with sealing elements that press against the conveyor belt for sealing and allow the first and second covers to move simultaneously with the conveyor belt. The pushing assembly includes: The pushing component is mounted on the machine body; The push block is set on the piston rod of the pusher. In the initial state, the push block is detached from the moving block. When the first cover and the second cover need to be moved back, the push block pushes the moving block, the first cover and the second cover back to their original positions. The push block moves away from the moving block and remains detached.

[0010] By adopting the above technical solution, after the first and second covers move down, the sealing element presses against the conveyor belt. The movement of the conveyor belt causes the first and second covers to move simultaneously. The sealing element can achieve better sealing effect and better environmental protection effect, and also reduces the risk of the first and second covers not moving in sync with the die-cast parts, thus further realizing high efficiency and high quality.

[0011] The moving block, cover one, and cover two move simultaneously, causing the moving block to abut against the pushing block for positioning. The cleaning component and sandblasting component stop, and the pushing component starts to drive the pushing block to push the moving block, cover one, and cover two back to their original positions. Then, the pushing component drives the pushing block to move away from the moving block, thereby further achieving high efficiency and high quality.

[0012] Optionally, the lifting assembly includes: The lifting component is mounted on the machine body and connected to both cover body one and cover body two; A sensor is installed on the machine body and connected to the lifting component and the pushing component; after the lifting component drives the first and second covers to move upward and contact the sensor, the pushing component activates to drive the pushing block to approach and push the moving block back to its original position.

[0013] By adopting the above technical solution, the lifting component starts to drive the first and second covers to move downward, so that the sealing component is pressed against the conveyor belt for positioning. The cleaning component and the sandblasting component are started to process. After the processing is completed, the lifting component starts to drive the first and second covers to move upward and abut against the sensor. Then, the pushing component starts to drive the pushing block to push the moving block back.

[0014] Optionally, the cleaning component includes: A cleaning plate is installed inside the cover and has multiple cleaning holes facing the surface of the die-cast part; An air inlet pipe is installed on the cleaning plate and communicates with the cleaning hole, allowing gas to pass through the cleaning hole to clean the surface of the die casting. The output tube is installed on the first cover and is used to output the cleaned impurities.

[0015] By adopting the above technical solution, gas is sprayed onto the surface of the die-casting part through the air inlet pipe and multiple cleaning holes, causing impurities on the surface of the die-casting part to fall off. As the gas inside the shroud increases, the gas pushes the impurities out through the output pipe for collection, thereby cleaning the surface of the die-casting part and collecting the cleaned impurities.

[0016] Optionally, the second cover is provided with a discharge pipe for outputting sand. Both the discharge pipe and the outlet pipe are provided with a collection component, which is used to collect the impurities output from the discharge pipe and the sand output from the outlet pipe.

[0017] By adopting the above technical solution, the sandblasting component polishes the surface of the die-casting part by sandblasting. The sand is removed after impact polishing the surface of the die-casting part. Then the sand is output through the discharge pipe and collected by the collection component. At the same time, the output impurities and sand are collected separately, thereby further realizing the requirements of high efficiency, high quality and environmental protection.

[0018] Optionally, the sandblasting assembly includes: A sandblasting plate is installed on the second cover and has multiple sandblasting holes that spray sand towards the surface of the die-casting part. An input pipe is installed on the sandblasting plate and communicates with the sandblasting holes; The sand outlet pipe and the air outlet pipe are connected to the input pipe via a three-way valve; The sand outlet and the air outlet are connected to the sand outlet pipe and the air outlet pipe, respectively. The three-way valve connects the input pipe to the sand outlet and performs sandblasting and polishing on the surface of the die casting through the sandblasting hole. Alternatively, the three-way valve connects the input pipe to the air outlet pipe and performs air jet cleaning on the surface of the die casting through the sandblasting hole.

[0019] By adopting the above technical solution, during sandblasting, the three-way valve connects the output pipe to the sand outlet, and the sand outlet is activated, allowing sand to be sprayed through the sandblasting hole onto the surface of the die casting for polishing. The sand is collected through the discharge pipe. After polishing, the three-way valve is activated to connect the output pipe to the air outlet pipe, and gas is sprayed out through the sandblasting hole to clean the surface of the die casting. After cleaning, the sand is collected through the discharge pipe. Then, the detection component detects the surface of the die casting. If the surface quality of the die casting meets the standard, the process stops. If the surface quality of the die casting does not meet the standard, sandblasting and air cleaning continue, and the detection component is used for further detection. This achieves the requirements of high efficiency, high quality, environmental protection, and low cost.

[0020] Optionally, two collection components are provided, each connected to an output pipe and a discharge pipe respectively. The collection components include: A collection bag, fitted over the output pipe, is used to collect impurities or sand and to allow gas to pass through; The fastener secures the opening of the collection bag to the output pipe.

[0021] By adopting the above technical solution, impurities or sand can be collected through the collection bag, and the fixing component can fix or unlock the collection bag.

[0022] Optionally, the detection component includes; A vision inspection unit is located above the die casting and is used for visual inspection of the surface roughness of the die casting; The physical inspection unit contacts the surface of the die-cast part and inspects its roughness.

[0023] By adopting the above technical solution, the visual inspection unit performs visual inspection, which facilitates the detection of roughness at multiple locations on the surface of the die-casting. However, the accuracy of visual inspection is relatively poor. The physical inspection unit directly contacts the surface of the die-casting to detect roughness, which has better accuracy, but is not as convenient. Therefore, the surface roughness of the die-casting is first detected by the visual inspection unit. If the surface roughness of the die-casting meets the standard, the sandblasting component continues to perform sandblasting treatment, and then the visual inspection unit is used for inspection again, and then the process is repeated. If the surface quality of the die-casting meets the standard, the physical inspection unit then detects the surface roughness of the die-casting to verify the accuracy of the visual inspection unit.

[0024] If the visual inspection unit has errors, it is necessary to repair or replace it. Therefore, the combination of visual and physical inspection units can improve inspection efficiency and accuracy, and further achieve the requirements of high efficiency, high quality, environmental protection and low cost.

[0025] Optionally, the physical detection unit includes: The detection block is slidably mounted on the second cover along the sliding direction of the moving block; The driving component is used to drive the movement of the detection block; The detection element is set on the detection block and in contact with the surface of the die-casting part. The detection element is used to detect roughness and is electrically connected to the sandblasting assembly. In the initial state, the detection element is located outside the surface of the die-casting part. During detection, the detection element moves after contacting the surface of the die-casting part under the action of the detection block and is used to detect the surface roughness of the die-casting part.

[0026] By adopting the above technical solution, before inspection, the inspection piece is located on the outer side of the die-cast part surface. When inspection is required, the driving component is activated to drive the inspection piece to press against the die-cast part surface and move on the die-cast part surface to inspect the surface roughness of the die-cast part. After inspection, the driving component drives the inspection piece to move to the outer side of the die-cast part surface to verify the accuracy of the vision inspection unit during inspection, which further improves the inspection situation and makes the process more efficient, high-quality, environmentally friendly and low-cost.

[0027] Secondly, this application provides a rapid surface treatment method for die-cast parts, which adopts the following technical solution: A rapid surface treatment method for die-cast parts includes the following steps: Conveying: The conveyor belt transports multiple die-cast parts while maintaining a certain distance between adjacent die-cast parts; The cleaning and sandblasting process begins. Covers 1 and 2 move downwards, positioning the seals against the conveyor belt. The conveyor belt drives multiple die-cast parts, covers 1 and 2, to move simultaneously. The cleaning component initiates air-blast cleaning of the die-cast parts within cover 1. The inspection component checks the surface roughness of the die-cast parts within cover 2. Based on the inspection data, the sandblasting component performs sandblasting and polishing on the die-cast parts within cover 2, and air-blast cleaning on the surface. The inspection component continues to check the surface roughness of the die-cast parts. If the surface roughness is not up to standard, polishing and air-blast cleaning continue. If the surface roughness is up to standard, the cleaning and sandblasting components stop, covers 1 and 2 move upwards and then back, and the process is repeated.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. The die-cast parts are pressed against the conveyor belt by cover body one and cover body two, respectively. Two adjacent die-cast parts are moved into cover body one and cover body two. The die-cast parts, cover body one, and cover body two move simultaneously. The cleaning component cleans the die-cast parts, and the detection component first detects the surface roughness of the die-cast parts. Based on the detected values, the sandblasting component performs sandblasting and polishing treatment on the surface of the die-cast parts. The detection component detects the surface roughness of the die-cast parts. If the surface roughness of the die-cast parts meets the standard, the sandblasting component stops, cover body one and cover body two move upwards and then back to their original positions, allowing the cleaned die-cast parts to move into cover body two for sandblasting treatment. After the surface of the die-cast parts is cleaned, it is then detected by the detection component, thereby improving the accuracy of the detection. This allows the sandblasting component to accurately calculate parameters such as the amount and intensity of sandblasting, improving the sandblasting and polishing effect and efficiency. Furthermore, since the cleaning and sandblasting are carried out within cover body one and cover body two, the risk of impurities and sand escaping into the external environment is reduced, thus achieving the requirements of high efficiency, high quality, environmental protection, and low cost.

[0029] 2. After the first and second covers move downwards, the seals press against the conveyor belt. The movement of the conveyor belt causes the first and second covers to move simultaneously. The seals can achieve better sealing effect and better environmental protection effect. It also reduces the risk of the first and second covers not moving in sync with the die-cast parts, thus further realizing high efficiency and high quality. Attached Figure Description

[0032] The following provides a further detailed description of this application.

[0033] This application discloses a rapid surface treatment device and method for die-cast parts.

[0034] Reference Figure 1 A rapid surface treatment device for die castings includes a machine body 1, a conveyor belt 11, and a sandblasting mechanism 2. The conveyor belt 11 is horizontally arranged on the machine body 1 and is used to horizontally transport multiple die castings 12, so that a certain distance is maintained between two adjacent die castings 12. The sandblasting mechanism 2 is used to sandblast the surface of the die castings 12 to achieve polishing and cleaning treatment.

[0035] Reference Figures 1-4 The sandblasting mechanism 2 includes a moving block 21, a pushing component 3, a first cover 22 and a second cover 23, a lifting component 4, a cleaning component 5, a sandblasting component 6, and a detection component 8. Mounting frames 13 located on both sides of the conveyor belt 11 are fixedly installed on the machine body 1. The moving block 21 is slidably installed on the opposite side walls of the mounting frame 13 along the moving direction of the die-casting part 12. The sliding direction of the moving block 21 is parallel to the moving direction of the die-casting part 12, and the moving block 21 is located above the conveyor belt 11. The pushing component 3 is set on the mounting frame 13 and is used to drive the moving block 21 to move. The conveyor belt 11 starts to drive the die-casting part 12 to move from the moving block 21 toward the pushing component 3.

[0036] Cover body 1 22 and cover body 23 are vertically slidable along the sliding direction of moving block 21 and mounted on the side walls at both ends of moving block 21. Lifting component 4 is mounted on mounting frame 13 and is used to drive cover body 1 22 and cover body 23 to move vertically upward or downward. Cleaning component 5 and sandblasting component 6 are respectively connected to the inside of cover body 1 22 and cover body 23. Conveyor belt 11 drives multiple die-cast parts 12 to pass through cover body 1 22 and cover body 23 in sequence. Detection component 8 is mounted on cover body 23 and is used to detect the surface roughness of die-cast parts 12. Detection component 8 is electrically connected to sandblasting component 6.

[0037] Both the first cover 22 and the second cover 23 are fixedly installed with elastic sealing elements 14. The sealing elements 14 are made of elastic sealing material, such as rubber. After the first cover 22 and the second cover 23 move down, the two sealing elements 14 press against the conveyor belt 11 to perform positioning and sealing, reducing the risk of substances inside the first cover 22 and the second cover 23 escaping into the external environment, and enabling the conveyor belt 11 to synchronize the movement of the die-cast part 12 with the first cover 22 and the second cover 23.

[0038] The lifting assembly 4 drives the first cover 22 and the second cover 23 to move downwards, causing the seals 14 located on the first cover 22 and the second cover 23 to press against the conveyor belt 11 for positioning and sealing. This also moves two adjacent die-cast parts 12 into the first cover 22 and the second cover 23. The conveyor belt 11 drives multiple die-cast parts 12, the first cover 22, and the second cover 23 to move simultaneously. The cleaning assembly 5 starts cleaning the surface of the die-cast parts 12 and collects the impurities after cleaning. The detection assembly 8 is used to detect the impurities inside the second cover 23 after cleaning. The surface quality of the die-cast part 12 is inspected. The sandblasting component 6 performs sandblasting on the surface of the die-cast part 12 according to the surface roughness of the die-cast part 12 detected by the detection component 8, and collects the sand after treatment. Then the detection component 8 is used to detect the surface roughness of the die-cast part 12 after sandblasting. If the detection value does not meet the standard, the sandblasting treatment is continued, and the roughness is detected again, thereby completing the surface treatment of the die-cast part 12. Then the cover body 1 22 and cover body 23 move upward and then move back to their original positions.

[0039] The pushing assembly 3 includes a pushing member 31 and a pushing block 32. The pushing member 31 can be an electric actuator or a cylinder, etc. The pushing member 31 is fixedly mounted on the side wall of the mounting bracket 13. The pushing member 31 is in a horizontal state and the piston rod extends horizontally to the side close to the moving block 21. The pushing block 32 is fixedly mounted on the piston rod of the pushing member 31. In the initial state, the pushing block 32 is detached from the moving block 21. When the first cover 22 and the second cover 23 need to be moved back, the pushing block 32 pushes the moving block 21, the first cover 22 and the second cover 23 back to their original positions, and the pushing block 32 moves away from the moving block 21 and remains detached. The pushing assembly 3 can also be an electric actuator connected to the moving block 21. The electric actuator drives the moving block 21, the first cover 22 and the second cover 23 and multiple die-cast parts 12 to move simultaneously.

[0040] The lifting assembly 4 includes a lifting component 41 and a sensor 42. The lifting component 41 is an electric push rod or a cylinder, etc. The lifting component 41 is fixedly installed on the top of the moving block 21 with the piston rod set vertically downward. The two side walls of the first cover 22 and the second cover 23 are fixedly connected by a fixing rod 24. The piston rod of the lifting component 41 is fixedly connected to the fixing rod 24. The sensor 42 is fixedly installed on the moving block 21. A control box for controlling the start and stop of the push component 31 and the lifting component 41 is fixedly installed on the mounting frame 13. The sensor 42 is electrically connected to the control box.

[0041] After the cleaning component 5 and sandblasting component 6 are completed, the moving block 21 abuts against the pushing block 32 for positioning. The lifting component 41 drives the first cover 22, the fixing rod 24 and the second cover 23 to move upward. After the fixing rod 24 contacts the sensor 42, the lifting component 41 stops. The pushing component 31 starts to drive the pushing block 32, the moving block 21, the first cover 22 and the second cover 23 to move back to their original positions. Then the pushing component 31 drives the pushing block 32 away from the moving block 21 and moves back to its original position.

[0042] The cleaning assembly 5 includes a cleaning plate 51, an air inlet pipe 52, and an outlet pipe 53. The cleaning plate 51 is fixedly installed on the inner top wall of the cover 22, and a cleaning hole 54 facing the surface of the die-cast part 12 is opened on the lower surface of the cleaning plate 51. At the same time, the lower surface of the cleaning plate 51 can also be designed according to the different shapes of the surface of the die-cast part 12. The cleaning plate 51 that is compatible with the surface of the die-cast part 12 can be replaced, thereby further improving the cleaning effect and saving energy.

[0043] The air inlet pipe 52 is fixedly installed on the cleaning plate 51 and extends through the cover 22 to the top of the cover 22. The air inlet pipe 52 is connected to the air source and is a flexible hose to accommodate the movement of the cover 22. The gas is blown onto the surface of the die-cast part 12 through the cleaning hole 54 to make the impurities on the surface of the die-cast part 12 fall off. The output pipe 53 is fixedly installed on the outer wall of the cover 22 and located near the bottom of the cover 22. The output pipe 53 is used to output the gas and the cleaned impurities.

[0044] The sandblasting assembly 6 includes a sandblasting plate 61, an input pipe 62, a sand outlet pipe 63, and an air outlet pipe 64. The sandblasting plate 61 is fixedly installed on the inner top wall of the second housing 23, and the lower surface of the sandblasting plate 61 has sandblasting holes 66 facing the surface of the die-cast part 12. The lower surface of the sandblasting plate 61 can also be designed according to different shapes of the die-cast part 12 surface. By replacing the sandblasting plate 61 with one whose lower surface is adapted to the die-cast part 12 surface, the sandblasting and polishing effect can be further improved. The input pipe 62 is fixedly installed on the upper surface of the sandblasting plate 61. The input pipe 62 passes through the second housing 23 and extends to the outside of the second housing 23. The sand outlet pipe 63 and the air outlet pipe 64 are connected to the input pipe 62 through a three-way valve 65. Both the sand outlet pipe 63 and the air outlet pipe 64 are flexible hoses designed to accommodate the movement of the second housing 23.

[0045] The equipment includes a sand ejector and an air ejector. The sand ejector is a shot blasting machine, connected to the sand ejector pipe 63 and used to supply sand. The air ejector is an air tank or air source, connected to the air ejector pipe 64 and used to supply gas. A three-way valve 65 connects the input pipe 62 to the sand ejector, allowing sand to be ejected through the sandblasting hole 66 to sandblast and polish the surface of the die-casting part 12. Alternatively, the three-way valve 65 connects the input pipe 62 to the air ejector pipe 64, allowing gas to be ejected through the sandblasting hole 66 to perform air jet cleaning on the surface of the die-casting part 12.

[0046] A discharge pipe 25 is fixedly installed on the outer wall of the second cover 23 and near the bottom of the second cover 23. Both the input pipe 62 and the discharge pipe 25 are equipped with a collection component 7 for collecting the output material. The two collection components 7 are the same. The following explanation will take the collection component 7 located on the input pipe 62 as an example.

[0047] The collection component 7 includes a collection bag 71 and a fixing member 72. The collection bag 71 is fitted onto the inlet of the inlet pipe 62 and is used to collect impurities or sand while allowing gas to pass through. The fixing member 72 is a clamp or binding wire, etc., which fixes the inlet of the collection bag 71 onto the inlet pipe 62, thereby achieving the collection of impurities and sand and improving the collection effect. The inlet pipe 62 and the outlet pipe 25 are flexible hoses, with one end fixedly installed on the machine body 1, thereby positioning the two collection bags 71 and preventing them from moving simultaneously with the first cover 22 and the second cover 23.

[0048] The detection component 8 includes a vision detection unit 81 and a physical detection unit 9. Both the vision detection unit 81 and the physical detection unit 9 are electrically connected to the control box to control the start and stop of the sandblasting component 6 based on the detection data of the vision detection unit 81 and the physical detection unit 9. The vision detection unit 81 is fixedly installed on the inner side wall of the cover 23 and is a non-contact roughness detector, so as to quickly obtain the surface roughness of the die-cast part 12 through visual inspection. The physical detection unit 9 contacts the surface of the die-cast part 12 to detect the roughness.

[0049] After the die-cast part 12 is moved into the housing 23, the vision inspection unit 81 is used to inspect the surface roughness of the die-cast part 12 and transmits the inspection data to the control box. The control box adjusts the parameters such as the sand discharge speed and quantity of the sand discharge component according to the inspection value. The sand discharge component starts to polish the surface of the die-cast part 12. After the treatment is completed, the three-way valve 65 is activated, so that the gas passes through the sandblasting hole 66 to clean the surface of the die-cast part 12, causing the sand to fall off. The vision inspection unit 81 continues to inspect. If the inspection value of the surface of the die-cast part 12 does not meet the standard, the sandblasting and air blasting cleaning is continued, and the vision inspection unit 81 is inspected again until the inspection value meets the standard.

[0050] Once the value detected by the vision inspection unit 81 meets the standard, the physical inspection unit 9 is activated to press against the surface of the die-casting part 12 and move to detect the surface roughness of the die-casting part 12, thereby verifying the accuracy of the detection data of the vision inspection unit 81. If the roughness is greater than the specified value, sandblasting and air blasting are continued, and the roughness is then detected by the physical inspection unit 9 again, until the detection data meets the standard and then stops.

[0051] The physical testing unit 9 includes a testing block 91, a driving component 92, and a testing component 93. The testing block 91 is slidably mounted on the inner wall of the housing 23 along the surface of the die-cast part 12. The driving component 92 is an electric actuator, which is fixedly mounted on the outer wall of the housing 23, and its piston rod is connected to the testing block 91 and drives the testing block 91 to move. The testing component 93 is a contact roughness tester, which is fixedly mounted on the testing block 91. In the initial state, the testing component 93 is located outside the surface of the die-cast part 12. During testing, the testing component 93 moves and presses against the surface of the die-cast part 12 and moves on the surface of the die-cast part 12 to detect the surface roughness of the die-cast part 12.

[0052] When inspection is required, the driving component 92 drives the inspection component 93 to approach the surface of the die-cast part 12, so that the inspection component 93 moves against the surface of the die-cast part 12. The inspection component 93 is used to inspect the surface roughness of the die-cast part 12 to verify the accuracy of the inspection value of the vision inspection unit 81. If the inspection value of the vision inspection unit 81 is verified to be correct, the polishing and air cleaning are completed. Otherwise, if the inspection value of the vision inspection unit 81 is verified to be incorrect, the inspection component 93 is separated from the surface of the die-cast part 12, and polishing and air cleaning continue. Then the inspection continues until the surface roughness of the die-cast part 12 meets the standard.

[0053] The working principle of this application embodiment is as follows: The conveyor belt 11 drives multiple die-cast parts 12 to move, and a certain distance is formed between two adjacent die-cast parts 12. When two adjacent die-cast parts 12 move to the bottom of the first cover 22 and the second cover 23, the lifting component 41 starts to drive the first cover 22 and the second cover 23 to move down, so that the sealing component 14 presses against the conveyor belt 11 for positioning and sealing. The two adjacent die-cast parts 12 move into the first cover 22 and the second cover 23 respectively. The conveyor belt 11 drives the die-cast parts 12, the first cover 22 and the second cover 23 to move simultaneously. Gas is blown onto the surface of the die-cast parts 12 through the cleaning hole 54 to clean impurities. The impurities enter the collection bag 71 through the output pipe 53 for collection, thereby cleaning the surface of the die-cast parts 12. After cleaning, the die-cast parts 12 move into the second cover 23 in the next cycle.

[0054] During cleaning inside the housing 22, the vision inspection unit 81 first inspects the surface roughness of the die-cast part 12. Based on the inspection value, the sandblasting hole 66 performs sandblasting and polishing on the surface of the die-cast part 12. The sand is also collected in the collection bag 71 through the discharge pipe 25. The sandblasting hole 66 stops blasting, and the gas cleans the surface of the die-cast part 12 through the sandblasting hole 66. When the gas output stops, the vision inspection unit 81 continues to inspect the surface roughness of the die-cast part 12. If the roughness does not meet the standard, the sandblasting hole 66 continues to blast sand for polishing and air cleaning until the surface roughness of the die-cast part 12 meets the standard.

[0055] The physical inspection unit 9 is activated and presses against the surface of the die-casting 12 and moves on the surface of the die-casting 12 to detect the surface roughness of the die-casting 12, thereby verifying the detection accuracy of the visual inspection unit 81. If the roughness does not meet the standard, sandblasting, polishing and air cleaning continue. If the roughness meets the standard, sandblasting, polishing and air cleaning are completed. The lifting component 41 is activated to drive the first cover 22 and the second cover 23 to move upward. The pushing component 31 is activated to drive the first cover 22 and the second cover 23 to move back to their original positions and continue the next cycle. This improves the sandblasting effect and efficiency. Moreover, the cleaning and sandblasting are carried out inside the first cover 22 and the second cover 23, reducing the risk of impurities and sand escaping into the external environment, thereby meeting the requirements of high efficiency, high quality, environmental protection and low cost.

[0056] This application discloses a method for rapid surface treatment of die-cast parts.

[0057] Reference Figures 1-4 A rapid surface treatment method for die-cast parts includes the following steps: Conveying: The conveyor belt 11 conveys multiple die-cast parts 12, and maintains a certain distance between two adjacent die-cast parts 12; The process involves cleaning and sandblasting / polishing. Cover 1 (22) and Cover 2 (23) move downwards, causing the seal 14 to press against the conveyor belt 11 for positioning. The conveyor belt 11 drives multiple die-cast parts 12, Cover 1 (22), and Cover 2 (23) to move simultaneously. The cleaning component 5 initiates air-blast cleaning of the die-cast parts 12 within Cover 1 (22). The detection component 8 detects the surface roughness of the die-cast parts 12 within Cover 2 (23). Based on the detection data, the sandblasting component 6 performs sandblasting and polishing on the die-cast parts 12 within Cover 2 (23), and air-blast cleaning on the surface of the die-cast parts 12. The detection component 8 continues to detect the surface roughness of the die-cast parts 12. If the surface roughness is not up to standard, polishing and air-blast cleaning continue. If the surface roughness is up to standard, the cleaning component 5 and sandblasting component 6 stop, Cover 1 (22) and Cover 2 (23) move upwards and then back, and the process is repeated to complete the surface treatment of multiple die-cast parts 12, thereby achieving the requirements of high efficiency, high quality, environmental protection, and low cost.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
