Description

Technical Field

[0001] This utility model relates to the field of sandblasting technology, specifically to a production line for automated loading and unloading of sandblasting materials. Background Technology

[0002] With the continued prosperity and development of the building decoration and bathroom industries, consumers' demands for product aesthetics, quality, and personalization are constantly rising. Corrugated panels, with their unique wave-like shapes, can add rich visual effects to architectural spaces and are widely used in interior and exterior wall decoration, ceilings, and other fields; shower platforms are key components in modern bathroom spaces for enhancing comfort and aesthetics. The market demand for these two types of products is showing a rapid growth trend.

[0003] To meet the ever-growing market demand and stand out in fierce market competition, enterprises need to continuously improve production efficiency and product quality stability. Traditional manual production methods, when faced with large-scale production tasks, have gradually revealed numerous problems such as low efficiency and inconsistent quality, making them difficult to adapt to the rapid pace of modern industrial development. Automated production, as a key means to improve production efficiency and quality control, has become an inevitable trend in industry development. In the production process of corrugated sheet materials and shower platforms, sandblasting is an important process that gives the product surface a unique texture and protective properties. However, if the closely related loading and unloading process still relies on manual operation, it will severely restrict the automation level and efficiency improvement of the entire production process. Therefore, the development of a production line specifically designed for automated sandblasting loading and unloading of corrugated sheet materials and shower platforms is urgently needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a production line for automated loading and unloading of sandblasting materials. Through the coordinated action of a clamping mechanism, a vacuum adsorption mechanism, and an anti-drop mechanism, automated loading and unloading of corrugated sheets and shower platforms can be achieved, meeting production needs.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A production line for automated loading and unloading of sandblasting components includes a loading device, an input device, an output device, a unloading device, a feeding trolley, a first limiting guide assembly, an output trolley, a second limiting guide assembly, and a control mechanism. The loading device, input device, output device, and unloading device are electrically connected to the control mechanism. The feeding trolley moves within the first limiting guide assembly, and the output trolley moves within the second limiting guide assembly. A sandblasting device is disposed between the input device and the output device. The first limiting guide assembly is perpendicular to the input device and adjacent to the inlet of the input device. The second limiting guide assembly is perpendicular to the output device and adjacent to the outlet of the output device. The loading device is rotatably disposed between the input device and the first limiting guide assembly, and the unloading device is rotatably disposed between the output device and the second limiting guide assembly. The loading device and the unloading device have the same structure, and each includes at least two sets of clamping mechanisms, at least two sets of vacuum adsorption mechanisms, and at least two sets of anti-drop mechanisms.

[0007] Preferably, the feeding device includes a first robotic arm and a first moving device connected to the first robotic arm, and the unloading device includes a second robotic arm and a second moving device connected to the second robotic arm.

[0008] Preferably, the first mobile device includes a connecting base, a connecting member, and a bracket. The connecting member is disposed on the connecting base, and the connecting plate at the top of the connecting member is rotatably connected to the output end of the first robot. The connecting base is connected to the bracket, and the bracket is provided with at least two sets of gripping mechanisms, two sets of vacuum adsorption mechanisms, and two sets of anti-drop mechanisms.

[0009] Preferably, there are four sets of the clamping mechanism, the vacuum adsorption mechanism, and the anti-drop mechanism.

[0010] Preferably, the bracket includes a first support frame, a second support frame, and an even number of support columns. The first support frame and the second support frame are symmetrically arranged on both sides of the connecting seat, and the even number of support columns are evenly distributed on the first support frame and the second support frame. A set of clamping mechanisms is provided on the two symmetrical support columns with the transverse center line of the bracket as the axis of symmetry.

[0011] Preferably, the gripping mechanism includes a first gripper, a second gripper, and a gripper cylinder. The first gripper and the second gripper are respectively fixed on two support columns, and the first gripper and the second gripper are respectively connected to the gripper cylinder.

[0012] Preferably, the anti-fall mechanism includes a first anti-fall component, a second anti-fall component, and an anti-fall cylinder. The first anti-fall component and the second anti-fall component are respectively fixed on two symmetrical support columns with the transverse center line of the bracket as the axis of symmetry. The first anti-fall component and the second anti-fall component are respectively connected to the anti-fall cylinder. The first gripper and the first anti-fall component are respectively fixed on both sides of one support column, and the second gripper and the second anti-fall component are respectively fixed on both sides of the other support column.

[0013] Preferably, the vacuum adsorption mechanism is disposed between the first anti-drop component and the anti-drop component. Multiple support rods are provided on both the first support frame and the second support frame. A fixing member is connected to the bottom of each support rod. The lower end of the fixing member is fixedly connected to the vacuum suction cup of the vacuum adsorption mechanism. The height of the vacuum suction cup is higher than the height of the clamping mechanism by the thickness of the product to be sandblasted.

[0014] Preferably, both the input device and the output device are hydraulic lifting conveyor roller tables.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] (1) Since corrugated sheets and shower platforms typically have irregular shapes and surfaces, the automated loading and unloading production line for sandblasting provided by this utility model can be adaptively adjusted according to the specific shape of the product by setting two sets of clamping mechanisms with adjustable grippers and other components. For corrugated sheets, the grippers can conform to the undulating surface of the sheet, find a suitable point of force for clamping, and ensure that the sheet will not slip due to shaking during the transfer process. For larger products such as shower platforms that may have edges of different shapes, the clamping mechanism can clamp relatively stable parts, such as the edge of the platform or the supporting structure, to achieve reliable gripping.

[0017] Furthermore, the surface of corrugated panels may be quite smooth, and a clamping mechanism alone may not provide sufficient holding force. The vacuum adsorption mechanism creates a vacuum environment upon contact with the panel surface, using atmospheric pressure to firmly adhere the panel to the adsorption surface, further enhancing the fixation effect and making it more stable during gripping and transfer. For shower platforms, if the surface has a smooth decorative surface, vacuum adsorption can also assist the clamping mechanism to prevent displacement of the platform during movement.

[0018] During the grabbing and transfer of corrugated panels and shower platforms, there is a certain risk of them falling due to their irregular shape and potentially uneven weight distribution. An anti-fall mechanism provides additional protection while the gripping and vacuum suction mechanisms are operating. For example, if the gripping mechanism momentarily loosens or the vacuum suction fails unexpectedly, the anti-fall mechanism can quickly activate, using its designed blocking components to prevent the corrugated panels or shower platforms from falling, effectively protecting the product and avoiding damage and production interruptions caused by falls.

[0019] (2) The production line for automated loading and unloading of sandblasting provided by this utility model can realize automated loading and unloading of wave boards and shower platforms through the synergistic effect of the clamping mechanism, vacuum adsorption and anti-drop mechanism, thus meeting production needs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] See Figures 1 to 4 This utility model discloses a production line for automated loading and unloading of sandblasting components, including a loading device 1, an input device 2, an output device 3, a unloading device 4, a feeding trolley 6, a first limiting guide assembly 7, an unloading trolley 8, a second limiting guide assembly 9, and a control mechanism 10. The loading device 1, input device 2, output device 3, and unloading device 4 are electrically connected to the control mechanism 10. The feeding trolley 6 moves within the first limiting guide assembly 7, thereby guiding the feeding trolley 6 to a specific position for convenient feeding. The unloading trolley 8 moves within the second limiting guide assembly 9, thereby guiding the unloading trolley to a specific position for convenient unloading. A sandblasting device 5 is installed between the input device 2 and the output device 3. The sandblasting device 5 is used to sandblast the product. The first limiting guide component 7 is perpendicular to the input device 2 and is adjacent to the inlet of the input device 2. The second limiting guide component 9 is perpendicular to the output device 3 and is adjacent to the outlet of the output device 3. The loading device 1 is rotatably installed between the input device 2 and the first limiting guide component 7, so that the product can be transferred from the feeding trolley 6 to the input device 2. The unloading device 4 is rotatably installed between the output device 3 and the second limiting guide component 9, so that the sandblasted product can be transferred from the output device 3 to the unloading trolley 8. The loading device 1 and the unloading device 4 have the same structure. Both the loading device 1 and the unloading device 4 include at least two sets of clamping mechanisms 124, at least two sets of vacuum adsorption mechanisms 126, and at least two sets of anti-drop mechanisms 125.

[0042] The production line for automated loading and unloading of sandblasting provided by this utility model can achieve automated loading and unloading of product 16 (wave board or shower platform) by setting up a clamping mechanism 124, a vacuum adsorption mechanism 126 and an anti-drop mechanism 125 working together to meet production needs.

[0043] Specifically, the feeding device 1 includes a first robotic arm 11 and a first moving device 12 connected to the first robotic arm 11, and the unloading device 4 includes a second robotic arm 41 and a first moving device 12 connected to the second robotic arm 41.

[0044] It should be noted that the feeding device 1 and the unloading device 4 have the same structure, and the first moving device 12 and the second moving device 42 also have the same structure. The following uses the first moving device 12 as an example to explain the specific structure of the first moving device 12. The specific structure of the second moving device 42 will not be described in detail.

[0045] Specifically, the first moving device 12 includes a connecting seat 121, a connecting member 122, and a bracket. The connecting member 122 is disposed on the connecting seat 121, and a connecting plate 1221 is disposed on the top of the connecting member 122. The connecting plate 1221 is rotatably connected to the first robotic arm 11, so that the first robotic arm 11 can drive the feeding device 1 to rotate. This allows the feeding device 1 to rotate within a suitable angle range so as to accurately pick up products from the feeding trolley 6 and transfer them to the input device 2, realizing the function of flexibly adjusting position and posture during the feeding process. The connecting seat 121 is connected to the bracket. At least two sets of clamping mechanisms 124, two sets of vacuum adsorption mechanisms 126, and two sets of anti-drop mechanisms 125 are provided on the bracket. In this embodiment, there are four sets of clamping mechanisms 124, vacuum adsorption mechanisms 126, and anti-drop mechanisms 125. The four sets of clamping mechanisms 124 are symmetrically arranged on the first support frame 1231 and the second support frame 1232 with the longitudinal center line of the connecting seat 121 as the axis of symmetry. The four sets of vacuum adsorption mechanisms 125 and the four sets of anti-drop mechanisms 126 are symmetrically arranged on the first support frame 1231 and the second support frame 1232 with the longitudinal center line of the connecting seat as the axis of symmetry. The four sets of anti-drop mechanisms 126 are symmetrically arranged on the first support frame 1231 and the second support frame 1232 with the longitudinal center line of the connecting seat as the axis of symmetry.

[0046] Specifically, the support includes a first support frame 1231, a second support frame 1232, and an even number of support columns 1233. In this embodiment, there are eight support columns 1233. The first support frame 1231 and the second support frame 1232 are symmetrically arranged on both sides of the connecting seat 121. The eight support columns 1233 are evenly distributed on the first support frame 1231 and the second support frame 1232. A set of clamping mechanisms 124 are provided on the two symmetrical support columns with the transverse center line of the support as the axis of symmetry.

[0047] Specifically, four support columns 1233 are vertically connected to the outer edges of both sides of the first support frame 1231, and four support columns 1233 are vertically connected to the outer edges of both sides of the second support frame 1232. A set of clamping mechanisms 124 are fixed on the two support columns 1233 near the first end 12311 of the first support frame 1231, a set of clamping mechanisms 124 are fixed on the two support columns 1233 near the second end of the first support frame 1231, a set of clamping mechanisms 124 are fixed on the two support columns 1233 near the first end 12321 of the second support frame 1232, and a set of clamping mechanisms 124 are fixed on the two support columns 1233 near the second end of the second support frame 1232.

[0048] Specifically, each set of gripping mechanisms 124 includes a first gripper 1241, a second gripper (not shown in the figure), and a gripper cylinder 1243. The first gripper 1241 and the second gripper are respectively mounted on two support columns 1233. The first gripper 1241 and the second gripper are respectively connected to the gripper cylinder 1243, thereby activating the gripper cylinder 1243. The first gripper 1241 and the second gripper can move closer or further away. When the first gripper 1241 and the second gripper of multiple sets of gripping mechanisms 124 approach each other, the product 16 can be clamped.

[0049] Specifically, each set of anti-fall mechanisms 125 includes a first anti-fall component 1251, a second anti-fall component 1252, and an anti-fall cylinder 1253. The first anti-fall component 1251 and the second anti-fall component 1252 are respectively fixedly mounted on two support columns 1233. The first anti-fall component 1251 and the second anti-fall component 1252 are respectively connected to the anti-fall cylinder 1253, so that the anti-fall cylinder 1253 can drive the first anti-fall component 1251 and the second anti-fall component 1252 to move up and down. The first gripper 1241 and the first anti-fall component 1251 are respectively fixed on both sides of one support column 1233, and the second gripper and the second anti-fall component 1252 are respectively fixed on both sides of the other support column 1233.

[0050] Specifically, the vacuum adsorption mechanism 126 is disposed between the first anti-drop component 1251 and the second anti-drop component 1252. Multiple support rods 1234 are provided on both the first support frame 1231 and the second support frame 1232. In this embodiment, there are a total of four support rods. Each support rod 1234 is connected to a fixing member 1235. The lower end of the fixing member 1235 is fixedly connected to the vacuum suction cup 1261 of the vacuum adsorption mechanism 126. The height of the vacuum suction cup 1261 is higher than the height of the clamping mechanism 124 by the thickness of the product. Thus, when the clamping mechanism 124 clamps the product, the vacuum adsorption mechanism 126 is activated, and the vacuum suction cup 1261 can pick up the product, ensuring that the product 16 will not fall.

[0051] In this embodiment, the clamping mechanism 124 can be adaptively adjusted according to the specific shape of the product through its adjustable gripper components. For corrugated panels, the grippers can conform to the undulating surface of the panel, find a suitable point of force for clamping, and ensure that the panel will not slip due to shaking during transfer. For larger products such as shower platforms that may have edges of different shapes, the clamping mechanism can clamp relatively stable parts, such as the edge of the platform or the supporting structure, to achieve reliable gripping.

[0052] Furthermore, the surface of the corrugated sheet material may be relatively smooth, and the clamping mechanism 124 alone may not provide sufficient fixing force. The vacuum adsorption mechanism 126 creates a vacuum environment upon contact with the sheet material surface, using atmospheric pressure to firmly adhere the sheet material to the adsorption surface, further enhancing the fixing effect on the corrugated sheet material and making it more stable during gripping and transfer. For shower platforms, if the surface has a smooth decorative surface, vacuum adsorption can also assist the clamping mechanism to prevent displacement of the platform during movement.

[0053] During the grabbing and transfer of corrugated panels and shower platforms, there is a certain risk of them falling due to their irregular shape and potentially uneven weight distribution. The anti-fall mechanism 125 provides additional protection while the clamping mechanism 124 and vacuum adsorption mechanism 126 are operating. For example, if the clamping mechanism momentarily loosens or the vacuum adsorption fails unexpectedly, the anti-fall mechanism 125 can quickly activate, using the first and second anti-fall components to prevent the corrugated panels or shower platforms from falling, effectively protecting the products and avoiding damage and production interruptions caused by falls.

[0054] Specifically, both input device 2 and output device 3 are hydraulic lifting conveyor roller tables. Input device 2 is used to transport the product to the work station of sandblasting device 5 for sandblasting, and output device 3 is used to transport the sandblasted product to the work station of unloading device 4.

[0055] In this embodiment, both the input device 2 and the output device 3 are hydraulic lifting conveyor roller tables, which can quickly and accurately adjust the height of the conveyor roller table according to different production needs and processes. For example, when docking with the sandblasting device 5, the height can be easily matched through the hydraulic system, ensuring a smooth transition between devices and reducing problems such as material jamming or falling due to height differences.

[0056] Furthermore, during the production process, if the product needs to be sandblasted at different heights, the hydraulic lifting conveyor roller table can be adjusted to the corresponding height at any time, improving the flexibility and adaptability of production.

[0057] Specifically, the production line for automated loading and unloading of sandblasting includes a fence 13. A feeding trolley 6 feeds materials from the entrance 131 of the fence 13, and an unloading trolley 8 exits from the exit 132 of the fence 13, transporting the materials to a designated location. The control mechanism 10 is located within the fence 13.

[0058] Specifically, the production line for automated loading and unloading of sandblasting also includes a vision device 14 electrically connected to the control mechanism 10, which is set above the loading device 1, so as to identify the product type and retrieve the gripping program of the corresponding product. The vision device 14 is fixed on the fixing frame 15, which is set on the fence 13.

[0059] During operation, a worker pushes the feeding trolley 6 from the entrance 131 of the fence 13 to the end of the first limiting guide component 7. The product type is identified by the vision device 14, and then the gripping program for the corresponding product is retrieved. The feeding device 1 starts running, and the clamping mechanism 124 starts clamping the product. After clamping the product, the vacuum suction cup 1261 is activated to pick up the product. The first robotic arm is slowly raised to a certain height, and the anti-drop mechanism 125 is activated to prevent the product from falling. The first robotic arm rotates to transfer the product to the input device 2. The input device 2 then transports the received product to the location of the sandblasting device 5. The sandblasting device 5 performs sandblasting on the input product. After sandblasting, the product is received by the output device 3 from the sandblasting device 5 and continues to be transported. When the sandblasted product reaches the vicinity of the outlet of the output device 3, the unloading device 4 (the specific working steps are the same as the loading device 1) grabs the product from the output device 3 and transfers it to the unloading trolley 8. The unloading trolley 8 is manually pulled out from the second limit guide component 9 and then goes out from the outlet 132 of the fence 13. Finally, the sandblasted product is transported to the designated storage location.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
