[0061] The embodiment of the present application provides a sand blasting equipment, which comprises:

[0062] a machine body 200;

[0063] a conveying mechanism 210 arranged on the machine body 200 and used for conveying a workpiece to be blasted;

[0064] a turnover mechanism 220 connected with the conveying mechanism 210, the turnover mechanism 220 being used for supporting and overturning the workpiece to be blasted, and the conveying mechanism 210 being used for driving the turnover mechanism 220 to move the workpiece to be blasted;

[0065] a sand blasting mechanism 300 arranged on the machine body 200, and the sand blasting mechanism 300 having at least one sand blasting head;

[0066] The turnover mechanism 220 is used for overturning the workpiece to be blasted, so that at least two surfaces of the workpiece to be blasted are respectively directed towards the at least one sand blasting head.

[0067] The at least one sand blasting head is used for respectively blasting the at least two surfaces of the workpiece to be blasted.

[0068] The sandblasting apparatus in this embodiment includes a body 200, a conveyor mechanism 210, a tilting mechanism 220, and a sandblasting mechanism 300. The body 200 provides structural support and a stable base for the entire apparatus. The conveyor mechanism 210, typically a conveyor belt or roller system, is mounted on the body 200 and is used to continuously or step-by-step transport the workpiece to be sandblasted to the sandblasting area.

[0069] The flip mechanism 220, such as a rotating bracket 400 or a movable tray, is connected to the conveying mechanism 210 and is used to hold and flip the workpiece to be sandblasted so that different surfaces of the workpiece can face the sandblasting head.

[0070] The sandblasting mechanism 300 is equipped with at least one sandblasting head, which can be of a fixed or adjustable design to achieve uniform sandblasting treatment on the surface of the workpiece.

[0071] During operation, the workpiece is first placed on the conveying mechanism 210 and then conveyed to the position of the flipping mechanism 220. In the first case, a sandblasting head sandblasts the four sides of the workpiece from multiple angles, and the flipping of the workpiece is completed by the flipping mechanism 220. In the second case, the conveying mechanism 210 drives the flipping mechanism 220 and the workpiece to move to a preset position, and the flipping mechanism 220 flips the workpiece at this position. During this period, multiple sandblasting heads can be set to sandblast different surfaces of the workpiece at the same time, increasing efficiency and uniformity of effect. This system design allows for continuous flow processing of workpieces, thereby greatly reducing downtime and manual intervention and improving production efficiency. The sandblasting equipment of the utility model can realize automatic conveying and flipping of workpieces, as well as automatic sandblasting of multiple sides, thereby significantly improving production efficiency and product quality. In addition, the equipment reduces manual handling and positioning errors of workpieces during processing, reduces labor intensity and production costs, and increases the stability and reliability of the work process.

[0072] In the technical solution of this embodiment, the sandblasting equipment includes a body 200, a conveying mechanism 210, a flipping mechanism 220 and a sandblasting mechanism 300. The conveying mechanism 210 is installed on the body 200 and is responsible for transporting the workpiece to be sandblasted to a designated position. The flipping mechanism 220 is connected to the conveying mechanism 210 and is used to carry and flip the workpiece so that the workpiece can automatically adjust its posture during transportation. The sandblasting mechanism 300 is also provided on the body 200 and is equipped with at least one sandblasting head. During operation, the flipping mechanism 220 flips the workpiece to ensure that at least two surfaces of the workpiece can be aligned with the sandblasting head respectively. In this way, each sandblasting head can effectively sandblast different surfaces of the workpiece. This design realizes automatic conveying, automatic flipping and automatic sandblasting of multiple surfaces of the workpiece, greatly improving production efficiency and product quality.

[0073] Referring to Figure 3 In this embodiment, the sandblasting mechanism 300 includes at least two sandblasting heads, which are arranged in sequence along the conveying direction of the conveying mechanism 210;

[0074] The turnover mechanism 220 is used to turn the workpiece to be sandblasted, so that at least two surfaces of the workpiece to be sandblasted face the at least two sandblasting heads respectively;

[0075] Each sandblasting head is used to sandblast a surface of the workpiece to be sandblasted respectively.

[0076] In this embodiment, the conveying mechanism 210 is installed on the machine body 200 and is responsible for stably conveying the workpiece to be sandblasted to the sandblasting area. The turnover mechanism 220 is closely connected with the conveying mechanism 210 and can be driven by a motor with controllable turning angle, which allows the workpiece to be adjusted to a specific angle as needed during transmission, ensuring that each surface can be accurately aligned with the sandblasting head.

[0077] The sandblasting mechanism 300 includes at least two sandblasting heads, which are arranged in sequence along the conveying direction of the conveying mechanism 210 to adapt to the continuous production process. Each sandblasting head is responsible for a specific surface of the workpiece.

[0078] For example, in this embodiment, the first sandblasting head is responsible for the first and second surfaces 102 of the workpiece, and the second sandblasting head is responsible for the third and fourth surfaces 104.

[0079] At the beginning of the operation, the workpiece to be sandblasted is placed on the conveying mechanism 210 and starts to move. The workpiece first reaches the position of the first sandblasting head, at which time the turnover mechanism 220 adjusts the workpiece to an angle suitable for sandblasting the first surface 101 according to the preset program. After completion, the workpiece continues to move forward and is timely turned to the second surface 102, which is also processed by the first sandblasting head. Subsequently, the workpiece continues to move forward to the position of the second sandblasting head and is again adjusted by the turnover mechanism 220 so that the third and fourth surfaces 104 are aligned with the sandblasting heads respectively, and the sandblasting operation of the remaining surfaces is completed.

[0080] The beneficial effect of this design is that by precisely controlling the turning angle and optimizing the layout of the sandblasting heads, the uniformity and efficiency of sandblasting are improved, and the handling and repositioning of the workpiece during processing are reduced, significantly reducing production cost and time.

[0081] Further improve the design of the sandblasting equipment to improve the precision and efficiency of the sandblasting process. By configuring a double-sandblasting head system, each sandblasting head individually processes a specific surface of the workpiece to be sandblasted, thereby achieving higher quality surface treatment.

[0082] Referring to Figure 3In this embodiment, the sandblasting mechanism 300 includes a first sandblasting head 301 and a second sandblasting head 302, which are arranged along the conveying direction of the conveying mechanism 210;

[0083] The turnover mechanism 220 is used to turn the workpiece to be sandblasted during the movement driven by the conveying mechanism 210, so that the first surface 101 of the workpiece to be sandblasted faces the first sandblasting head 301, and the second surface 102 adjacent to the first surface 101 on the workpiece to be sandblasted faces the second sandblasting head 302;

[0084] The first sandblasting head 301 is used to sandblast the first surface 101 of the workpiece to be sandblasted;

[0085] The second sandblasting head 302 is used to sandblast the second surface 102 of the workpiece to be sandblasted.

[0086] In this embodiment, the sandblasting mechanism 300 includes two sandblasting heads, the first sandblasting head 301 and the second sandblasting head 302, which are arranged along the conveying direction of the conveying mechanism 210. Such a layout allows each sandblasting head to focus on a single surface, ensuring maximum sandblasting quality.

[0087] The design of the turnover mechanism 220 allows precise control of the turning action of the workpiece. When the workpiece is moved to the position of the first sandblasting head 301 by the conveying mechanism 210, the turnover mechanism 220 adjusts the workpiece so that the first surface 101 faces the first sandblasting head 301. Then, the workpiece continues to move forward, and the turnover mechanism 220 adjusts again so that the second surface 102 faces the second sandblasting head 302, preparing for subsequent sandblasting operations.

[0088] At the beginning of the work, the workpiece to be sandblasted is placed on the conveying mechanism 210 and starts to move along the predetermined path. First, the workpiece is conveyed to the working area of the first sandblasting head 301, at which time the turnover mechanism 220 adjusts the workpiece so that the first surface 101 faces upwards, and the first sandblasting head 301 then starts to sandblast this surface. After completion, the workpiece continues to move to the working area of the second sandblasting head 302. Here, the turnover mechanism 220 again turns the workpiece so that the second surface 102 faces upwards, and the second sandblasting head 302 performs precise sandblasting.

[0089] The main advantage of this design is that it can achieve higher efficiency and better sandblasting effect. Since each sandblasting head is responsible for sandblasting a single surface, the sandblasting pressure and coverage can be more precisely controlled, thereby improving the uniformity of sandblasting and the surface quality. In addition, the independent sandblasting head arrangement also reduces cross-contamination during sandblasting, ensuring cleaner and more precise surface treatment. Overall, the use of this equipment not only improves the degree of automation of the production line, but also significantly improves production efficiency and product consistency.

[0090] With reference to the drawings Figure 3 In this embodiment, the conveying mechanism 210 is used to drive the turnover mechanism 220 to move the workpiece to be blasted along a first horizontal direction;

[0091] The sandblasting mechanism 300 further comprises:

[0092] A first moving assembly 311 is arranged above the conveying mechanism 210, and the first moving assembly 311 is used to drive the first sandblasting head 301 to move along a second horizontal direction, so that the first sandblasting head 301 dynamically sandblasts the first surface of the workpiece to be blasted along the second horizontal direction;

[0093] A second moving assembly 312 is arranged above the conveying mechanism 210 and is spaced apart from the first moving assembly 311, and the second moving assembly 312 is used to drive the second sandblasting head 302 to move transversely relative to the conveying direction of the conveying mechanism 210, and the second moving assembly 312 is used to drive the second sandblasting head 302 along the second horizontal direction, so that the second sandblasting head 302 sandblasts the second surface of the workpiece to be blasted along the second horizontal direction;

[0094] The first horizontal direction and the second horizontal direction intersect each other.

[0095] The sandblasting device in this embodiment is suitable for large-sized workpieces, such as the middle frame 100 of a mobile phone or a tablet computer, which may have a width exceeding the sandblasting coverage of a single sandblasting head. Therefore, the device comprises ingeniously designed moving assemblies to achieve the dynamic transverse movement of the sandblasting heads, ensuring that the entire surface can be uniformly and effectively sandblasted. Specifically, the first moving assembly 311 and the second moving assembly 312 are arranged above the conveying mechanism 210, and both assemblies are designed as sliding modules. These sliding modules can adopt a combination of precise linear guides and servo motors, allowing the sandblasting heads to dynamically move along the width direction (i.e., transversely) of the conveying mechanism 210. This design allows the sandblasting heads to cover a wider workpiece surface, especially for workpieces with a larger width.

[0096] During the sandblasting process, the first sandblasting head 301 is driven by the first moving assembly 311 to dynamically move transversely along the first surface 101 of the workpiece, ensuring that the surface can receive uniform sandblasting treatment from one end to the other. Similarly, the second sandblasting head 302 is driven by the second moving assembly 312 to perform the same dynamic sandblasting treatment on the second surface 102 of the workpiece.

[0097] This embodiment allows each sandblasting head to accurately cover the surface area it is responsible for through dynamic transverse movement, thereby ensuring the uniformity and efficiency of sandblasting. This is particularly important for precision components that require high-quality surface treatment, such as the middle frame 100 of a mobile phone or a tablet computer.

[0098] With reference to the drawings Figure 3 In this embodiment, the sandblasting mechanism 300 further comprises:

[0099] A first lifting assembly 321 is arranged at the execution end of the first moving assembly 311, for driving the first sandblasting head 301 to move up and down;

[0100] A second lifting assembly 322 is arranged at the execution end of the second moving assembly 312, for driving the second sandblasting head 302 to move up and down.

[0101] In this embodiment, the first lifting assembly 321 and the second lifting assembly 322 are both arranged at the execution end of the corresponding moving assembly. These lifting assemblies can adopt hydraulic or electric lifting systems, enabling the sandblasting heads to dynamically adjust their positions in the vertical direction (relative to the conveying direction of the conveying mechanism 210) to adapt to different heights or shapes of the workpiece surface. This vertical movement allows the sandblasting heads to approach or move away from the surface of the workpiece as needed, thereby achieving precise control of the intensity and coverage of sandblasting.

[0102] At the beginning of the sandblasting operation, the workpiece is placed on the conveying mechanism 210 and starts to move along the predetermined route. As the workpiece enters, the first sandblasting head 301 is controlled by the first lifting assembly 321 to adjust its height according to the specific needs of the first surface 101 of the workpiece, ensuring the uniformity and effectiveness of the sandblasting operation. The second sandblasting head 302 is also controlled by the second lifting assembly 322 to perform similar height adjustments and sandblasting processes on the second surface 102.

[0103] The main advantage of this design is to provide fine control over the position of the sandblasting heads, enabling the device to adapt to various workpieces of different heights and shapes. By precisely adjusting the distance of the sandblasting heads, the intensity and range of sandblasting can be optimized, ensuring the uniformity and quality of sandblasting. This is particularly important for workpieces with complex shapes or varying sizes, such as the middle frame 100 of a mobile phone or tablet.

[0104] Taking the middle frame 100 of a mobile phone as an example, it generally has four surfaces. In this embodiment, four sandblasting heads are used to handle the four surfaces respectively, with reference to Figure 9 In this embodiment, the sandblasting mechanism 300 includes a third sandblasting head 303 and a fourth sandblasting head 304, which are arranged in a spaced manner along the conveying direction of the conveying mechanism 210;

[0105] The turnover mechanism 220 is used to turn over the workpiece to be sandblasted during the movement of the conveying mechanism 210, so that the third surface adjacent to the first surface and the second surface on the workpiece to be sandblasted faces the first sandblasting head 301, and the fourth surface arranged adjacent to the second surface on the workpiece to be sandblasted faces the fourth sandblasting head;

[0106] The third sandblasting head 303 is used for sandblasting the third surface 103 of the workpiece to be sandblasted;

[0107] The fourth sandblasting head 304 is used for sandblasting the fourth surface 104 of the workpiece to be sandblasted.

[0108] In this embodiment, the sandblasting mechanism 300 now includes four sandblasting heads: the first sandblasting head 301, the second sandblasting head 302, the third sandblasting head 303, and the fourth sandblasting head 304. These sandblasting heads are sequentially and spaced apart along the conveying direction of the conveying mechanism 210 to accommodate the positioning needs of the workpiece during conveying.

[0109] The turnover mechanism 220 plays a key role in this embodiment, not only supporting the precise turnover of the workpiece, but also ensuring that each surface can be accurately aligned with its corresponding sandblasting head. When the workpiece enters the sandblasting area, the turnover mechanism 220 adjusts the workpiece so that the first surface 101 faces the first sandblasting head 301, the second surface 102 faces the second sandblasting head 302, and so on, until the fourth surface 104 is aligned with the fourth sandblasting head 304.

[0110] At the beginning of the sandblasting operation, the mobile phone frame 100 workpiece to be sandblasted is placed on the conveying mechanism 210. As the workpiece moves, it first reaches the working area of the first and second sandblasting heads 302. At this time, the turnover mechanism 220 precisely adjusts the workpiece to ensure that the first surface 101 and the second surface 102 are respectively aligned with the respective sandblasting heads. The workpiece continues to move forward, and then is further adjusted by the turnover mechanism 220, so that the third surface 103 and the fourth surface 104 respectively reach directly below the third and fourth sandblasting heads 304 for subsequent sandblasting treatment.

[0111] This embodiment realizes the separate processing of each surface of the mobile phone frame 100 by configuring four sandblasting heads respectively, optimizing the coverage efficiency and quality of sandblasting. In addition, the precise control of the turnover mechanism 220 not only improves the processing speed, but also ensures the uniformity of sandblasting and the consistency of surface treatment.

[0112] Referring to Figure 3 In this embodiment, the third moving assembly 313 is arranged above the conveying mechanism 210 to drive the third sandblasting head 303 to move transversely relative to the conveying direction of the conveying mechanism 210, and the third moving assembly 313 is used to drive the third sandblasting head 303 to dynamically sandblast the third surface 103 of the workpiece to be sandblasted;

[0113] The fourth moving assembly 314 is arranged above the conveying mechanism 210 and is spaced apart from the fourth moving assembly 314, and is used to drive the fourth sandblasting head 304 to move transversely relative to the conveying direction of the conveying mechanism 210, and the fourth moving assembly 314 is used to drive the fourth sandblasting head 304 to dynamically sandblast the fourth surface 104 of the workpiece to be sandblasted.

[0114] In this embodiment, the third and fourth mobile assemblies 313 and 314 are designed as modules capable of dynamic movement in the transverse direction above the conveying mechanism 210. These assemblies can employ linear drive systems, such as linear motors or rail systems, allowing precise control of the movement of the blasting heads across the width of the workpiece. This arrangement enables the blasting heads to dynamically perform blasting from one end to the other according to the needs of the workpiece surface, ensuring uniform treatment of each part.

[0115] When the workpiece to be blasted enters the blasting area, the first and second blasting heads 302 first perform blasting treatment on the first and second surfaces 102 of the workpiece. As the workpiece continues to move, the third blasting head 303 begins to blast the third surface 103, a process controlled by the third mobile assembly 313. The third mobile assembly 313 drives the third blasting head 303 to move transversely along the width of the workpiece, ensuring that each part of the third surface 103 receives uniform blasting.

[0116] Similarly, the treatment of the fourth surface 104 is completed by the fourth mobile assembly 314 and the fourth blasting head 304. The fourth mobile assembly 314 ensures that the fourth blasting head 304 can move transversely along the width of the workpiece, thereby providing comprehensive and uniform blasting treatment to the fourth surface 104.

[0117] This embodiment makes the blasting process more efficient by providing dynamic transverse movement, increasing the flexibility of the production line, and improving the quality and consistency of workpiece surface treatment. In addition, by reducing the number of manual adjustments or repeated blasting, production costs and time are greatly reduced, making the equipment suitable for mass production needs.

[0118] Referring to Figure 3 In this embodiment, the third lifting assembly 323 is provided at the execution end of the third mobile assembly 313, used to drive the third blasting head 303 to move vertically relative to the conveying direction of the conveying mechanism 210, so as to approach or move away from the third surface 103 of the workpiece to be blasted.

[0119] The fourth lifting assembly 324 is provided at the execution end of the fourth mobile assembly 314, used to drive the fourth blasting head 304 to move vertically relative to the conveying direction of the conveying mechanism 210, so as to approach or move away from the fourth surface 104 of the workpiece to be blasted.

[0120] In this embodiment, the third and fourth lifting assemblies 323 and 324 are respectively installed at the execution ends of the third and fourth mobile assemblies 314. These lifting assemblies can be achieved through hydraulic, pneumatic or electric mechanical systems, allowing the blasting heads to dynamically adjust their positions in the vertical direction. In this way, the blasting heads can be closer to or farther away from the surface of the workpiece, adjusting the intensity and range of blasting according to the processing needs.

[0121] During the dynamic sandblasting process, when the workpiece enters the sandblasting area through the conveying mechanism 210, the third and fourth sandblasting heads 304 start their work according to the specific needs of the workpiece. For example, if the third surface 103 is relatively uneven or has special height requirements, the third lifting assembly 323 will adjust the height of the third sandblasting head 303 accordingly to ensure uniform sandblasting coverage and prevent damage to the workpiece. Similarly, the fourth sandblasting head 304 will also adjust the height according to the specific circumstances of the fourth surface 104 to achieve the best sandblasting effect.

[0122] In this embodiment, by precisely adjusting the height of the sandblasting head, the impact force and coverage range of the sandblasting medium can be controlled, thereby improving the uniformity and quality of the sandblasting process. The addition of the lifting assembly enables the device to handle workpieces of different heights and shapes, increasing the applicability and flexibility of the device.

[0123] Referring to Figure 5 In this embodiment, the conveying mechanism 210 includes a support 400 and two parallel and spaced conveying chains 500 arranged on the support 400;

[0124] The turnover mechanism 220 includes a clamping component 224 and a bearing shaft 225. The clamping component 224 is used to clamp the workpiece to be sandblasted, and the bearing shaft 225 is connected to the clamping component 224, with both ends of the bearing shaft 225 rotatably connected to the two conveying chains 500 to drive the clamping component 224 and the workpiece to be sandblasted to move under the drive of the two conveying chains 500;

[0125] The sandblasting device also includes a turnover triggering assembly arranged between the two conveying chains 500, and the turnover triggering assembly is used to drive the clamping component 224 and the workpiece to be sandblasted to turn over while moving.

[0126] In this embodiment, the conveying mechanism 210 includes a support 400 and two parallel conveying chains 500 arranged on the support 400. This design enables the conveying mechanism 210 to stably support and transport the workpiece, while providing the necessary motion support for the turnover mechanism 220.

[0127] The turnover mechanism 220 is composed of a clamping component 224 and a bearing shaft 225. The clamping component 224 is used to firmly clamp the workpiece to be sandblasted, and the bearing shaft 225 is connected to the clamping component 224, with both ends of the bearing shaft 225 rotatably connected to the two conveying chains 500. This design allows the clamping component 224 to drive the workpiece to be sandblasted to move along the conveying line under the drive of the two conveying chains 500, while achieving the turnover of the workpiece.

[0128] The turnover triggering assembly is arranged between the two conveying chains 500, and is used to drive the clamping component 224 in movement at a critical moment to drive the workpiece to be sandblasted to turn over. This assembly can accurately control the timing and angle of the workpiece turning over, and ensure that each surface can be accurately aligned with the corresponding sandblasting head for sandblasting.

[0129] When the workpiece is placed on the conveying mechanism 210, the clamping component 224 firmly clamps the workpiece and starts to move along the conveying chain 500. As the workpiece moves, the turnover triggering assembly activates at the appropriate position to cause the clamping component 224 to initiate the turnover of the workpiece. At this time, according to the new position of the workpiece after turning over, the corresponding sandblasting head starts to sandblast the surface in the new orientation. This process is repeated as the workpiece passes through the sandblasting area until all the necessary surfaces are sandblasted.

[0130] The automatic turnover mechanism reduces the need for manual adjustment of the workpiece, significantly improving the degree of automation and work efficiency of the production process.

[0131] Reference Figures 6 to 8 In this embodiment, the turnover triggering assembly at least includes a first trigger 221, a second trigger 222, and a third trigger 223, which are arranged in sequence along the conveying direction of the conveying mechanism 210.

[0132] The first trigger 221 is arranged to abut against the fourth surface 104 of the workpiece to be sandblasted, and is used to push against the clamping component 224 to rotate, so that the second surface 102 of the workpiece to be sandblasted faces the second sandblasting head 302.

[0133] The second trigger 222 is arranged to abut against the first surface 101 of the workpiece to be sandblasted, and is used to push against the clamping component 224 to rotate, so that the third surface 103 of the workpiece to be sandblasted faces the third sandblasting head 303.

[0134] The third trigger 223 is arranged to abut against the second surface 102 of the workpiece to be sandblasted, and is used to push against the clamping component 224 to rotate, so that the fourth surface 104 of the workpiece to be sandblasted faces the fourth sandblasting head 304.

[0135] In this embodiment, the turnover triggering assembly includes three triggers: a first trigger 221, a second trigger 222, and a third trigger 223, which are arranged in sequence along the conveying direction of the conveying mechanism 210. Each trigger is specially arranged to abut against a specific surface of the workpiece to drive the clamping component 224 to rotate accurately, thereby achieving correct alignment of the surface of the workpiece.

[0136] For example, the first trigger flips the trigger assembly 221 designed to abut the fourth surface 104 of the workpiece to be sandblasted. When the fourth surface 104 reaches the first trigger flips the trigger assembly 221, the trigger pushes the clamping component 224 to rotate, turning the second surface 102 of the workpiece to face the second sandblasting head 302.

[0137] The second trigger 222 abuts the first surface 101 of the workpiece. As the workpiece continues to advance, the second trigger 222 activates and pushes the clamping component 224 to rotate, causing the third surface 103 of the workpiece to face the third sandblasting head 303.

[0138] The third trigger 223 abuts the second surface 102 of the workpiece. The function of this trigger is to push the clamping component 224 to further rotate as the workpiece passes, aligning the fourth surface 104 of the workpiece with the fourth sandblasting head 304.

[0139] When the workpiece enters the sandblasting equipment, it is first securely clamped by the clamping component 224 and moves forward along the conveyor chain 500. When the workpiece reaches the first trigger flips the trigger assembly 221, the first trigger flips the trigger assembly 221 will push the clamping component 224 according to the preset program, so that the second surface 102 of the workpiece faces the second sandblasting head 302. Then, the workpiece continues to advance to the position of the second trigger 222, which again pushes the clamping component 224 to turn the third surface 103 to face the third sandblasting head 303. Finally, the third trigger 223 activates at the right time to complete the positioning of the fourth surface 104, ensuring that it faces the fourth sandblasting head 304.

[0140] In this embodiment, multiple triggers are used to continuously and automatically adjust the direction of the workpiece, ensuring that each surface is precisely sandblasted at the appropriate time. This highly automated flipping mechanism greatly reduces manual intervention, improves production efficiency, and ensures accuracy and repeatability in the processing process.
