Description

Technical Field

[0001] This invention relates to the field of sandblasting technology, and in particular to a sandblasting device with a simpler structure. Background Technology

[0002] Sandblasting is a surface treatment process that uses high-speed sand jets to impact the surface of a workpiece to achieve cleaning, strengthening, or finishing purposes. It is widely used in the processing of metal, glass, ceramic, and other products. On automated production lines, sandblasting equipment usually requires specialized fixtures to fix and protect the workpieces. Among these fixtures, the cover plate is a key component, used to cover non-processed areas of the workpiece during the sandblasting process or to provide positioning and protection.

[0003] Traditional automated sandblasting equipment, in order to achieve continuous production, typically includes separate loading, sandblasting, and unloading stations, equipped with corresponding loading and unloading robots. In processes involving the use of cover plates, existing solutions generally employ a separate loading mechanism for installing the cover plates and a separate unloading mechanism for removing them, requiring an additional storage mechanism for handling and temporarily storing these cover plates. For example, after completing a sandblasting cycle, the unloading mechanism moves the fixture with the workpiece to the unloading position and removes the cover plate, then sends the cover plate to the storage mechanism; subsequently, the loading mechanism retrieves the cover plate from the storage mechanism and installs it onto the fixture at the loading position, which is already loaded with a new workpiece, for the next round of sandblasting. However, the aforementioned existing solutions result in a complex mechanical layout and a large footprint for the entire sandblasting equipment. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a sandblasting device with a simpler structure.

[0005] According to an embodiment of the present invention, a sandblasting device with a simpler structure includes a first sandblasting circulation line, a first sandblasting module, a first robotic arm, and a first conveying module. The first sandblasting circulation line is provided with a first loading position, a first unloading position, and a first sandblasting position. The first sandblasting circulation line can drive a sandblasting fixture to pass sequentially through the first loading position, the first sandblasting position, and the first unloading position. The first sandblasting module is located on one side of the first sandblasting circulation line and is used to sandblast the workpiece on the sandblasting fixture at the first sandblasting position. The first robotic arm is located on one side of the first sandblasting circulation line and is used to load the workpiece to be sandblasted onto the sandblasting fixture at the first unloading position, or to unload the sandblasted workpiece from the sandblasting fixture at the first unloading position. The first conveying module is located on one side of the first sandblasting circulation line and is used to convey the cover plate of the sandblasting fixture located at the first unloading position onto the sandblasting fixture located at the first loading position.

[0006] A sandblasting device with a simpler structure according to an embodiment of the present invention has at least the following technical advantages: In the sandblasting equipment of this application, the basic architecture is constructed around a closed-loop first sandblasting circulation line. This first sandblasting circulation line, for example, can be a ring guide rail, belt conveyor, or chain conveyor, with a first loading position, a first sandblasting position, and a first unloading position sequentially arranged along its circulation path. The sandblasting fixture is placed on this circulation line and driven by the circulation line's own drive system, passing through the first loading position, the first sandblasting position, and the first unloading position sequentially according to a preset rhythm, completing a complete sandblasting cycle. When a sandblasting process is completed, the sandblasting fixture, carrying the sandblasted workpiece and its cover plate, arrives at the first unloading position, where a first robotic arm removes the workpiece. First, the first transport module removes the cover plate from the sandblasting fixture. Then, the first transport module moves to the first loading position and places the cover plate on the sandblasting fixture that has already loaded new workpieces to be sandblasted but does not yet have a cover plate. After the cover plate on the sandblasting fixture at the first unloading position is removed by the first transport module, the first robotic arm removes the sandblasted workpiece from the sandblasting fixture at the first unloading position, and then places the workpiece to be sandblasted on the sandblasting fixture at the first unloading position that does not have a workpiece loaded. The sandblasting fixture is then transported to the first loading position by the first sandblasting circulation line. This application achieves the recycling of the cover plate by transporting it between adjacent first unloading and first loading positions using the first transport module. This eliminates all intermediate buffers and transfer mechanisms, making the overall layout of the sandblasting equipment more compact, greatly simplifying the equipment structure, significantly reducing the floor space, and simultaneously reducing equipment manufacturing costs and maintenance complexity.

[0012] According to some embodiments of the present invention, a sandblasting device with a simpler structure includes a second flipping module comprising a third driving component, a second adsorption component, and a transfer component. The second adsorption component is used to adsorb sandblasting fixtures. The third driving component is connected to the second adsorption component and is used to drive the second adsorption component to flip 180°. A first robotic arm can unload workpieces onto the second adsorption component before flipping. The transfer component is used to carry the workpieces adsorbed by the second adsorption component after flipping.

[0023] The following is for reference. Figures 1 to 5 A sandblasting device with a simpler structure according to an embodiment of the present invention will be described in detail.

[0024] refer to Figures 1 to 3 According to an embodiment of the present invention, a sandblasting device with a simpler structure includes a first sandblasting circulation line 100, a first sandblasting module 200, a first robotic arm 300, and a first conveying module 400. The first sandblasting circulation line 100 is provided with a first loading position, a first unloading position, and a first sandblasting position. The first sandblasting circulation line 100 can drive a sandblasting fixture to sequentially pass through the first loading position, the first sandblasting position, and the first unloading position. The first sandblasting module 200 is disposed on one side of the first sandblasting circulation line 100. It is used to sandblast the workpiece on the sandblasting fixture at the first sandblasting position; the first robot 300 is located on one side of the first sandblasting circulation line 100, and the first robot 300 can load the workpiece to be sandblasted to the sandblasting fixture at the first unloading position, or unload the sandblasted workpiece on the sandblasting fixture at the first unloading position; the first conveying module 400 is located on one side of the first sandblasting circulation line 100, and is used to convey the cover plate of the sandblasting fixture located at the first unloading position to the sandblasting fixture located at the first loading position.

[0025] In the sandblasting equipment of this application, the basic architecture is constructed around a closed-loop first sandblasting circulation line 100. This first sandblasting circulation line 100, for example, can be a ring guide rail, belt conveyor, or chain conveyor 520. A first loading position, a first sandblasting position, and a first unloading position are sequentially arranged along its circulation path. The sandblasting fixture is placed on this circulation line and driven by the circulation line's own drive system, sequentially passing through the first loading position, the first sandblasting position, and the first unloading position according to a preset rhythm, completing a complete sandblasting process cycle. When a sandblasting process is completed, after the sandblasting fixture carries the sandblasted workpiece and its cover plate to the first unloading position, before the first robotic arm 300 removes the workpiece, the first... The first transport module 400 operates by first removing the cover plate from the sandblasting fixture; then, the first transport module 400 moves to the first loading position and places the cover plate on the sandblasting fixture that has been loaded with a new workpiece to be sandblasted but does not yet have a cover plate. After the cover plate on the sandblasting fixture at the first unloading position is removed by the first transport module 400, the first robot arm 300 removes the sandblasted workpiece from the sandblasting fixture at the first unloading position, and then places the workpiece to be sandblasted on the sandblasting fixture at the first unloading position that does not have a workpiece loaded, and the first sandblasting circulation line 100 transports the sandblasting fixture to the first loading position.

[0026] It is understandable that this application uses the first handling module 400 to handle the cover plate between the adjacent first unloading position and the first loading position, thereby realizing the recycling of the cover plate, eliminating all intermediate buffers and transfer mechanisms, making the overall layout of the sandblasting equipment more compact, greatly simplifying the equipment structure, significantly reducing the floor space, and reducing the equipment manufacturing cost and maintenance complexity.

[0027] It is understandable that this application simplifies the planning of the robot's motion trajectory and the layout of the equipment by concentrating the loading and unloading operations of the first robot 300 in one physical location, the first unloading position, and avoids the difficulty of setting up multiple independent operating positions in a small space.

[0028] refer to Figure 2 and Figure 3 In some embodiments of the present invention, the first conveying module 400 includes a first driving component 410 and a clamping component 420. The first driving component 410 is used to drive the clamping component 420 to move between a first unloading position and a first loading position, and the clamping component 420 is used to clamp or release the cover plate. It can be understood that the first driving component 410 drives the clamping component 420 to move directly above the sandblasting fixture at the first unloading position, and the clamping component 420 grips the cover plate; subsequently, the first driving component 410 drives the clamping component 420 to carry the cover plate to above the sandblasting fixture at the first loading position; finally, the clamping component 420 releases the cover plate, allowing it to fall smoothly onto the target sandblasting fixture, completing one conveying cycle.

[0029] refer to Figure 1 and Figure 2 In some embodiments of the present invention, the sandblasting equipment further includes a feeding module 500 and a first flipping module 600. The feeding module 500 supplies workpieces to the first flipping module 600, which flips the workpieces 180°. A first robotic arm 300 can load the workpieces flipped by the first flipping module 600 to a first unloading position. It is understood that the feeding module 500 transports the workpieces to the receiving position of the first flipping module 600, and then the first flipping module 600 flips the workpieces 180°. After the flipping is completed, the first robotic arm 300 moves to the first flipping module 600, picks up the workpieces that have been flipped 180°, and then loads them onto the sandblasting fixture located at the first unloading position.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, the feeding module 500 includes a feeding bin 510, a conveyor line 520, and a receiving bin 530. The first and last ends of the conveyor line 520 are connected to the feeding bin 510 and the receiving bin 530, respectively. The conveyor line 520 is provided with feeding positions for supplying a full-loaded workpiece tray to the first flipping module 600. It is understood that the full-loaded workpiece tray is sequentially pushed from the feeding bin 510 to the conveyor line 520, which then conveys it stepwise to the feeding position and precisely positions it. The first flipping module 600 then picks up the workpiece from the tray located at the feeding position and flips it. The empty tray is then conveyed by the conveyor line 520 to the receiving bin 530 for centralized recycling or reuse. The feeding bin 510 provides ample workpiece reserves, supporting long-term continuous operation of the equipment; the conveyor line 520 realizes automated flow from storage to the workstation with stable cycle time; and the receiving bin 530 completes the automatic recycling of empty material trays, forming a complete material flow closed loop. This greatly reduces the frequency of manual replenishment and handling, providing a solid foundation for achieving fully unmanned operation and improving the overall automation level of the line.

[0031] like Figure 2 and Figure 4 As shown, in one embodiment, the first flipping module 600 includes a second driving component 610 and a first adsorption component 620. The first adsorption component 620 is used to adsorb the workpiece on the feeding position, and the second driving component 610 is used to drive the first adsorption component 620 to flip 180°, so that the first adsorption component 620 drives the workpiece to flip 180°. It can be understood that the first adsorption component 620 moves above the workpiece on the feeding position and grasps the workpiece through vacuum adsorption; subsequently, the second driving component 610 is activated, driving the first adsorption component 620 and the adsorbed workpiece to rotate smoothly 180°; after rotating to the correct position, the first adsorption component 620 maintains the adsorption state, waiting for the first robotic arm 300 to grasp the workpiece.

[0032] refer to Figure 1 In some embodiments of the present invention, the sandblasting equipment further includes a second sandblasting circulation line 700, a second sandblasting module 800, a second robot arm 900, and a second flipping module 1000; the second sandblasting circulation line 700 is provided with a second loading position and a second sandblasting position, and the second sandblasting circulation line 700 can drive the sandblasting fixture to pass through the second loading position and the second sandblasting position in sequence; the second sandblasting module 800 is located on one side of the second sandblasting circulation line 700 and is used to sandblast the workpiece on the sandblasting fixture at the second sandblasting position; the first robot arm 300 can unload the workpiece from the first unloading position into the second flipping module 1000; the second flipping module 1000 is used to flip the workpiece 180°; the second robot arm 900 is located on one side of the second sandblasting circulation line 700 and is used to load the flipped workpiece from the second flipping module 1000 onto the sandblasting fixture at the second loading position.

[0033] Understandably, the workpiece that has undergone front-side sandblasting is picked up from the first unloading position by the first robot arm 300 and transferred to the second flipping module 1000. The second flipping module 1000 flips the workpiece 180° so that the other side of the un-sandblasted workpiece faces upward. Then, the second robot arm 900, located on one side of the second sandblasting circulation line 700, picks up the flipped workpiece from the second flipping module 1000 and loads it onto the sandblasting fixture located at the second loading position. Subsequently, the sandblasting fixture carries the workpiece into the second sandblasting position, where the second sandblasting module 800 performs sandblasting on the other side of the workpiece.

[0034] like Figure 1 and Figure 5 As shown, in some embodiments, the second flipping module 1000 includes a third driving component 1010, a second adsorption component 1020, and a transfer component 1030. The second adsorption component 1020 is used to adsorb sandblasting fixtures. The third driving component 1010 is connected to the second adsorption component 1020 and is used to drive the second adsorption component 1020 to flip 180°. The first robot arm 300 can unload the workpiece onto the second adsorption component 1020 before flipping. The transfer component 1030 is used to carry the workpiece adsorbed by the second adsorption component 1020 after flipping. The second robot arm 900 can load the workpiece on the transfer component 1030 to the second loading position. Understandably, the first robotic arm 300 places the workpiece with the first sandblasted surface onto the second adsorption component 1020 in its initial position, and the second adsorption component 1020 adsorbs and fixes it. Then, the third drive component 1010 drives the second adsorption component 1020 to rotate 180° together with the workpiece. After rotating into position, the second adsorption component 1020 releases the workpiece, allowing it to fall onto the transfer component 1030 below. Finally, the second robotic arm 900 picks up the workpiece from the transfer component 1030 and transfers it to the second loading position.

[0035] like Figure 1 As shown, in some embodiments, the second sandblasting circulation line 700 is further provided with a second unloading position. The second sandblasting circulation line 700 can drive the sandblasting fixture to sequentially pass through the second loading position, the second sandblasting position, and the second unloading position. The second robot arm 900 can unload the workpiece at the second unloading position. The sandblasting equipment also includes a second transport module, which is located on one side of the second sandblasting circulation line 700 and is used to transport the cover plate of the sandblasting fixture located at the second unloading position to the sandblasting fixture located at the second loading position. It can be understood that when the fixture that has completed double-sided sandblasting reaches the second unloading position and the second robot arm 900 unloads the final workpiece, the second transport module removes the cover plate from the fixture; then it moves to the second loading position and installs the cover plate onto the sandblasting fixture on which the workpiece that has completed the first side sandblasting was just placed by the second robot arm 900. The second transport module eliminates the need for a separate cover plate buffer and turnover mechanism for the second sandblasting system, maintaining the compactness of the entire double-sided sandblasting equipment layout. It not only retains the advantages of single-line equipment in saving space and simplifying structure, but also enables the cover plate to automatically match and flow with the fixture and workpiece from the first sandblasting to the second sandblasting, which greatly improves the degree of automation and production efficiency under complex processes.

[0036] Understandably, multiple trays full of workpieces are stored in the feeding bin 510. A tray full of workpieces is sequentially conveyed to the feeding position via the conveyor line 520. When a tray reaches the feeding position, a first lifting mechanism lifts the tray off the conveyor line. Then, a first robotic arm 300 grabs the workpiece from the tray, and the first lifting mechanism descends. The empty tray continues to be conveyed to the receiving bin 530 by the conveyor line. The conveyor line 520 also has a discharging position. When an empty tray is conveyed to the discharging position by the conveyor line, a second lifting mechanism lifts the empty tray. At this time, the second robotic arm 900 can place the workpieces that have undergone double-sided sandblasting into the empty tray. Then, the second lifting mechanism drives the tray containing the workpieces to descend onto the conveyor line 520. The conveyor line 520 then drives the tray containing the workpieces to move to the receiving bin 530, where the tray is stored.

[0037] refer to Figure 1 In some embodiments of the present invention, the first sandblasting circulation line 100 is further provided with an air blowing position, and the first sandblasting circulation line 100 can drive the sandblasting fixture to pass through the first loading position, the air blowing position, the first sandblasting position and the first unloading position in sequence; the sandblasting equipment also includes an air blowing module 1100, which is located on one side of the first sandblasting circulation line 100 and is used to blow air onto the sandblasting fixture at the air blowing position.

[0038] It should be noted that before sandblasting, dust, oil, water stains, or residues from previous processes that may be attached to the surface of the workpiece and fixture should be removed. If these impurities are brought into the sandblasting station, the high-speed sand particles may press them into the surface of the workpiece, forming defects, or affect the impact effect of the sand particles, resulting in uneven sandblasting.

[0039] Understandably, after the sandblasting fixture is loaded with the workpiece and the cover plate is installed, it moves to the air blowing position and stops. The air blowing module 1100 is started and uses a strong clean airflow to blow the exposed areas of the fixture and workpiece to remove dust, oil, water stains or residues from previous processes that may be attached to the surface of the workpiece and fixture before sandblasting.

[0040] refer to Figure 1 In some embodiments of the present invention, the first sandblasting circulation line 100 is further provided with a cleaning station. The first sandblasting circulation line 100 can drive the sandblasting fixture to pass sequentially through the first loading station, the first sandblasting station, the cleaning station, and the first unloading station. The sandblasting equipment also includes a cleaning module 1200, which is located on one side of the first sandblasting circulation line 100 and is used to clean the sandblasting fixture at the cleaning station. It is understood that the cleaning module 1200, which is located on one side of the cleaning station, has a structure similar to the air blowing module 1100 but may have higher air pressure or a different nozzle layout. It is used to powerfully blow away the sandblasted fixture. When the fixture reaches the cleaning station, the cleaning module 1200 is activated, using high-speed airflow to remove a large amount of abrasive dust and machining debris adhering to the surface, gaps, and cover plate of the fixture. The Cleaning Module 1200 ensures the relative cleanliness of the cover plate before and after handling, creating favorable conditions for precise gripping and installation of the cover plate, while also extending the service life of the fixture and related mechanisms and maintaining a clean production environment.

[0041] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
