Description

Technical Field

[0001] This application relates to the field of sandblasting technology, specifically to a flipping device and a sandblasting system. Background Technology

[0002] Sandblasting is a process that typically uses compressed air to create a high-speed jet that propels abrasive materials (such as copper ore sand, quartz sand, corundum, iron sand, and Hainan sand) onto the surface of the workpiece, causing changes to the surface or shape of the workpiece.

[0003] In related technologies, when sandblasting a workpiece, the workpiece to be sandblasted can be clamped onto a sandblasting fixture, and then the sandblasting fixture can be directly fed into a sandblasting machine to complete the sandblasting process of the product. If both sides of the workpiece need to be sandblasted, the sandblasting fixture needs to be flipped so that both sides of the workpiece can be sandblasted separately. The specific flipping process is as follows: the sandblasting fixture is transported to the flipping position by rollers, then the sandblasting fixture is stopped by a blocking cylinder, then the sandblasting fixture is positioned by a lifting cylinder, and then the sandblasting fixture is flipped 180 degrees by a rotating cylinder and a clamping cylinder.

[0004] However, the above-mentioned method requires stopping the sandblasting fixture before flipping it, which is inefficient. Furthermore, the flipping device is complex in structure, expensive, and prone to obstruction in the environment, resulting in a high failure rate. Utility Model Content

For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0040] When sandblasting a workpiece, the workpiece can be clamped and fixed by a sandblasting fixture, and then the sandblasting fixture can be directly fed into the sandblasting machine to complete the sandblasting process.

[0041] Reference Figure 1As shown, a sandblasting fixture 200 typically includes a fixture base 201, a connector 202, a fixture body 203, a rotating shaft 204, a magnet 206, and a handle 205. The connector 202 is connected to the fixture base 201. The middle part of the rotating shaft 204 is rotatably connected to the connector 202. Two fixture bodies 203 are provided, each connected to one end of the rotating shaft 204. The magnet 206 is located on the connector 202. The handle 205 is connected to the rotating shaft 204, and the handle 205 is made of metal or has a magnet, allowing the handle 205 to be attracted and fixed to the magnet 206. When flipping the sandblasting fixture 200, the handle 205 can be rotated to drive the rotating shaft 204 to rotate, thereby flipping the fixture body 203. When the fixture body 203 is flipped into position, the magnet 206 can be used to attract and fix the handle 205, thus fixing the fixture body 203 horizontally.

[0042] Reference Figure 2 As shown in the figure, an embodiment of this application discloses a flipping device 100, which includes a mounting base 1, a conveying mechanism 2, a position detection component 4, and a flipping mechanism 3. The mounting base 1 has a flipping position, and the conveying mechanism 2 is mounted on the mounting base 1 for conveying a sandblasting fixture 200. The position detection component 4 is disposed on the mounting base 1 for detecting whether the sandblasting fixture 200 has been conveyed to the flipping position. The flipping mechanism 3 is mounted on the mounting base 1 for flipping the sandblasting fixture 200 180 degrees when it is conveyed to the flipping position.

[0043] When flipping the sandblasting fixture 200, the sandblasting fixture 200 is placed on the conveying mechanism 2 so that the sandblasting fixture 200 can be driven to run by the conveying mechanism 2. During the operation of the sandblasting fixture 200, when the position detection component 4 detects that the sandblasting fixture 200 has run to the flip position, the flipping mechanism 3 cooperates with the sandblasting fixture 200 to limit the movement, so as to flip the sandblasting fixture 200 180 degrees.

[0044] Reference Figure 3 and Figure 4 As shown, the mounting base 1 includes a body 11, a mounting frame 12, and a sand collecting component 13. The top surface of the body 11 is open, and the mounting frame 12 is connected to the body 11 and located above the body 11. The conveying mechanism 2 and the position detection component 4 are respectively installed on the top surface of the body 11, and the flipping mechanism 3 is installed on the mounting frame 12 and located above the conveying mechanism 2. The sand collecting component 13 is connected to the body 11 and located below the conveying mechanism 2. During the operation of the sandblasting fixture 200 driven by the conveying mechanism 2, the abrasive material falling from the sandblasting fixture 200 can fall into the sand collecting component 13 for collection.

[0045] Reference Figure 5As shown, the flipping mechanism 3 includes a drive component 31, a gear transmission assembly 32, a rocker arm 33, and a hook 34. The drive component 31 and the gear transmission assembly 32 are respectively mounted on the mounting bracket 12, and the drive component 31 is connected to the gear transmission assembly 32, enabling the drive component 31 to drive the gear transmission assembly 32 to rotate. One end of the rocker arm 33 is connected to the gear transmission assembly 32, and the other end of the rocker arm 33 is connected to the hook 34, which is used to engage with the handle 205. When the drive component 31 drives the gear transmission assembly 32 to rotate, the gear transmission assembly 32 can drive the rocker arm 33 to swing, thereby achieving the purpose of flipping the sandblasting fixture 200.

[0046] In some embodiments, the drive unit 31 can be a rotary cylinder or a motor 21.

[0047] Reference Figure 6 As shown, the gear transmission assembly 32 includes a first gear 321, a second gear 322, and a third gear 323. The first gear 321, second gear 322, and third gear 323 are respectively mounted on the mounting bracket 12, with the second gear 322 and third gear 323 located on opposite sides of the first gear 321, and meshing with the first gear 321. A driving member 31 is connected to the first gear 321; when the driving member 31 drives the first gear 321 to rotate, it can drive the second gear 322 and third gear 323 to rotate respectively. One end of the rocker arm 33 is connected to the second gear 322 and the third gear 323 respectively via a connecting rod 35, and the other end of the rocker arm 33 extends towards the transmission mechanism 2 and is connected to the hook 34. When the drive unit 31 drives the first gear 321 to rotate, it can drive the second gear 322 and the third gear 323 to rotate respectively. Then, the second gear 322 and the third gear 323 drive the rocker arm 33 to swing, so that the hook 34 can push the handle 206 to rotate.

[0048] In this embodiment, a rotary cylinder can be used to drive three gear linkage mechanisms to rotate, so as to achieve smooth rotation of the swing arm 33. Then, the hook 34 is used to quickly rotate the handle 205 of the sandblasting fixture 200 counterclockwise by 180 degrees and then quickly return to its original position, so as to achieve dynamic flipping of the sandblasting fixture 200 on the V-shaped belt of the conveying mechanism 2.

[0049] Reference Figure 7 and Figure 8As shown, the conveying mechanism 2 includes a motor 21, a rotating shaft 22, a conveyor belt 23, and limiting members 24. Two rotating shafts 22 are provided, each rotatably connected to the machine body 11, and are spaced apart along the length of the machine body 11 at both ends. The conveyor belt 23 is wound around the two rotating shafts 22. The motor 21 is mounted on the machine body 11 and connected to one of the rotating shafts 22. The limiting members 24 are provided on the machine body 11, extending along the length of the machine body 11, and are used to guide and limit the conveying path of the sandblasting fixture 200. Multiple conveyor belts 23 and limiting members 24 are provided, forming two sets of conveying paths. When conveying the sandblasting fixture 200, the motor 21 drives the rotating shaft 22 to rotate, which in turn drives the conveyor belt 23 to rotate, thereby moving the sandblasting fixture placed on the conveyor belt 23.

[0050] In this embodiment, the conveyor belt 23 can be set as a V-shaped belt, so that under the action of the motor 21, the surface friction of the V-shaped belt can be used to transport the sandblasting fixture 200, and the V-shaped belt can avoid jamming caused by sand accumulation.

[0051] Continue to refer to Figure 8 As shown, the position detection component 4 includes a light-emitting device 41 and a light-receiving device 42, which are respectively disposed on the body 11 and located on both sides of the conveying mechanism 2. Exemplarily, when the sandblasting fixture 200 is not in the flip position, the light path between the light-emitting device 41 and the light-receiving device 42 is not blocked, and the light-receiving device 42 can receive the light emitted by the light-emitting device 41. When the sandblasting fixture 200 is in the flip position, the light path between the light-emitting device 41 and the light-receiving device 42 is blocked by the connector 202 of the sandblasting fixture 200, and the light-receiving device 42 cannot receive the light emitted by the light-emitting device 41. Therefore, whether the sandblasting fixture has reached the flip position can be confirmed based on whether the light-receiving device 42 receives the light emitted by the light-emitting device 41. Of course, in some embodiments, multiple sets of position detection components can also be provided, and each set of position detection components can be used to detect the operating position of the sandblasting fixture.

[0052] To prevent impurities from falling into the flipping mechanism 3 and motor 21 and affecting their normal operation, the flipping device 100 also includes a first housing 5 and a second housing 6. The first housing 5 covers the flipping mechanism 3, and the second housing 6 covers the motor 21. This allows the first housing 5 and the second housing 6 to prevent external impurities from falling into the flipping mechanism 3 and motor 21, ensuring their normal operation. (Refer to...) Figure 5 As shown.

[0053] In practical applications, the motor 21 is started, which drives the rotating shaft 22 to rotate. The rotating shaft 22 then drives the conveyor belt 23 to rotate, thereby moving the sandblasting fixture 200 placed on the conveyor belt 23. During the operation of the sandblasting fixture, when the position detection component 4 detects that the sandblasting fixture 200 has reached the flip position, the drive component 31 drives the first gear 321 to rotate. The first gear 321 then drives the second gear 322 and the third gear 323 to rotate respectively. The second gear 322 and the third gear 323 drive the swing arm 33 to swing, causing the hook 34 to engage with the handle 205 and push the handle 205 to rotate. The handle 205 then drives the rotating shaft 204 to rotate, thereby causing the fixture body 203 to flip. When the fixture body 203 is flipped into place, the handle 205 can be fixed by the magnet 206 to keep the fixture body 203 horizontal. Then, the drive component 31 drives the swing arm 33 to move back to the initial position.

[0054] Driven by a V-shaped belt, the sandblasting fixture 200 does not need to be stopped. Through a simple gear power mechanism and the speed difference between the front and rear belts, the sandblasting fixture 200 can automatically rotate 180 degrees during movement and then be attracted and fixed by magnet 206, thus realizing the automatic flipping function of the sandblasting fixture 200. It has high flipping efficiency, simple flipping mechanism, low cost, and low equipment failure rate.

[0055] Reference Figure 9 Accordingly, this application also discloses a sandblasting system, which includes a first sandblasting machine 300, a second sandblasting machine 400, and a tilting device 100 as described in any of the above embodiments. The first sandblasting machine 300 is disposed at one end of the tilting device 100 and includes a first conveying section. The second sandblasting machine 400 is disposed at the other end of the tilting device 100 and includes a second conveying section.

[0056] When the product is sandblasted, the product is fixed on the sandblasting fixture 200 and the sandblasting fixture 200 is conveyed by the first conveying part of the first sandblasting machine 300. During the conveying process of the sandblasting fixture 200, the first surface of the product can be sandblasted by the sandblasting part of the first sandblasting machine 300. After that, the sandblasting fixture 200 runs to the flipping mechanism 3 and is flipped 180 degrees by the flipping mechanism 3. Then, the sandblasting fixture 200 is conveyed by the second conveying part of the second sandblasting machine 400. During the conveying process of the sandblasting fixture 200, the second surface of the product can be sandblasted by the sandblasting part of the second sandblasting machine 400.

[0057] Compared to the conventional static positioning of the fixture in related technologies, followed by flipping by a simple gear power mechanism, this application effectively utilizes the speed difference and hook width between the conveying parts of the first and second sandblasting machines and the conveying mechanism of the flipping device to simultaneously flip the fixture handle 205 180 degrees during horizontal movement, thereby achieving automatic flipping of the sandblasting fixture 200. This saves equipment design costs and improves equipment stability. Furthermore, the use of a simple gear power mechanism and the speed difference between the front and rear belts enables the sandblasting fixture 200 to automatically flip during movement, resulting in a fast flipping speed and improved production efficiency.

[0058] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
