Description

Technical Field

[0001] The invention relates to the technical field of sandblasting, and in particular to an automatic sandblasting production line. Background Art

[0002] Sandblasting is a common surface treatment process. Its working principle is to use the impact of high-speed sand flow. Sandblasting is to accelerate the sand to a high-speed state through compressed air, and then let the high-speed sand flow impact the surface of the workpiece. According to Newton's second law, the sand has a large momentum when it moves at high speed. When they hit the surface of the workpiece, they will produce a strong impact force on the surface of the workpiece. This impact force can remove various pollutants, oxide layers, rust, etc. on the surface of the workpiece, and can also make the surface of the workpiece have a certain degree of roughness. For example, in mechanical processing, a layer of oxide scale will form on the surface of some metal parts after forging or heat treatment. Sandblasting can quickly and effectively remove this layer of oxide scale, so that the surface of the part can be restored to the original luster of the metal. It mainly has the functions of surface cleaning, surface roughening, and stress removal.

[0003] At present, most of the sandblasting processes are carried out on the workpiece through an automated sandblasting production line. During sandblasting, the workpiece is placed on a conveyor belt, which transports the workpiece into a sandblasting chamber for sandblasting. However, the current sandblasting production line cannot adjust the sandblasting range and sandblasting angle of the sandblasting port according to the size of the workpiece, resulting in a large amount of sand material being unable to be sprayed onto the surface of the workpiece during the sandblasting process, causing a certain amount of waste. At the same time, a single process cannot sandblast both sides of the workpiece, resulting in a long time for sandblasting. For this reason, an automated sandblasting production line is proposed.

[0040] Example 3

[0041] like Figure 1-14 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the clamping mechanism 6 includes a second cylinder 61, one end of the second cylinder 61 is fixedly connected to the inner wall of the sandblasting chamber 11, the output end of the second cylinder 61 is fixedly connected to a fixed plate 62, the surface of the middle part of the fixed plate 62 is fixedly connected to a flip assembly 63, the flip assembly 63 includes a second motor 631, the surface of the second motor 631 is fixedly connected to the surface of the fixed plate 62, one end of the rotating shaft of the second motor 631 is fixedly connected to a flip plate 632, both ends of the flip plate 632 are fixedly connected to a limiting block 633, the surface of the limiting block 633 is overlapped with a support plate 634, and the support plate The two ends of 634 are fixedly connected with a flip rack 635, and the surface of the flip rack 635 is meshed with a first gear 636.

A visual positioning camera 94 is fixedly connected to the surface of one end of the six-axis robot arm 92, and an air blowing nozzle 95 for cleaning the camera is fixedly connected to the surface of the support frame 91.

[0042] In this embodiment, when sandblasting the workpiece, the workpiece is stacked on the top of the material discharge cart 8, and the cart is pushed to move to a predetermined position. The six-axis robot arm 92 controls the movement of the second suction cup 93, and the visual positioning camera 94 is used to locate the position of the second suction cup 93. The workpiece is picked up by the second suction cup 93 and placed on the conveyor belt 21 for sandblasting. At the same time, the visual positioning camera 94 can also be cleaned by blowing air to avoid dust on the surface of the visual positioning camera 94 causing positioning deviation. After the workpiece is moved into the sandblasting chamber 11 by the conveyor belt 21, the first motor 32 drives the rotating plate 33 to move the first suction cup 36 above the workpiece, and the first cylinder 34 drives the first suction cup 36 to move downward, and after contacting the workpiece, the workpiece is picked up. After the second cylinder 61 drives the flip plate 632 to contact the workpiece, the first suction cup 36 puts the workpiece down, and the workpiece is supported by the support plate 634 below. 32, the rotating plate 33 rotates again, and the first suction cup 36 is reset to avoid blocking the sandblasting.

After the single-sided sandblasting is completed, the flip plate 632 is rotated under the action of the second motor 631 and the third motor 637. While turning the workpiece over, the first gear 636 drives the flip rack 635 to move, so that the support plate 634 slides along the limit block 633, so that the upper support plate 634 before flipping is changed to the lower support plate 634 supporting the workpiece, and the position of the upper support plate 634 before flipping is offset to avoid blocking the sandblasting, so that it can sandblast both sides of the workpiece. After the spraying is completed, the workpiece is placed back on the surface of the conveyor belt 21 by the lifting mechanism 3, and the workpiece is transported out of the sandblasting chamber by the conveyor belt 21, and the workpiece is taken down from the conveyor belt 21 by another set of six-axis manipulators 9, and placed on another material discharge cart to complete the sandblasting of a single workpiece.

[0043] The following is a detailed description of the working principle of the automated sandblasting production line.

[0044] like Figure 1-14As shown, when the workpiece is sandblasted, the workpiece is stacked on the top of the material discharge cart 8, and after the cart is pushed to the predetermined position, the second suction cup 93 is controlled to move by the six-axis robot arm 92, and the position of the second suction cup 93 is positioned by the visual positioning camera 94. The workpiece is picked up by the second suction cup 93 and placed on the conveyor belt 21 for sandblasting. At the same time, the setting of the visual positioning camera 94 can also clean the visual positioning camera 94 by blowing air to avoid dust on the surface of the visual positioning camera 94 causing positioning deviation. After the workpiece is moved into the sandblasting chamber 11 through the conveyor belt 21, the first motor 32 drives the rotating plate 33 to move the first suction cup 36 to the top of the workpiece, and the first cylinder 34 drives the first suction cup 36 to move to the top of the workpiece. 6 moves down, and after contacting the workpiece, the workpiece is picked up. After the flip plate 632 is driven by the second cylinder 61 to contact the workpiece, the first suction cup 36 puts the workpiece down, and the workpiece is supported by the support plate 634 below. Under the action of the first motor 32, the rotating plate 33 is rotated again to reset the first suction cup 36 to avoid blocking the sandblasting. Then the second cylinder 61 is started again, and the workpiece is clamped and fixed from both sides by the flip plate 632. During the operation of the second cylinder 61, the fixed plate 62 synchronously drives the second rack 72 to move, and the second rack 72 is meshed with the second gear 743, so that the second gear 743 drives the second synchronous wheel 742 to rotate, so that the second synchronous belt 75 meshing with the second synchronous wheel 742 drives the second transmission assembly 7 6 rotates, thereby causing the second gear 77 to push the first rack 55 meshing therewith to move, thereby pushing the adjustment block 52 into the diversion chamber 51, compressing the internal space of the diversion chamber 51 from both ends, and closing part of the nozzles 563, so that the sand material is concentrated and sprayed out from the nozzles 563 close to the center of the diversion chamber 51, so that more sand material can be directly sprayed onto the surface of the workpiece. At the same time, during the rotation of the second transmission component 76, the third synchronous belt 78 can also drive the third synchronous wheel 79 to rotate, so that the third synchronous wheel 79 drives the connecting rod 562 to rotate, thereby fine-tuning the direction position of the nozzle 563, and at the same time, it can also be connected through the first synchronous belt 57 to synchronously drive the multiple groups of sandblasting components 56 to deflect the angle, and adjust the sandblasting range again. The sand material is gathered to reduce the waste of sand material and improve the processing efficiency. When the sand material in the sand blasting pot 43 is sprayed out, the outside air is sucked in along the air inlet 42 through the air compressor 41, and injected into the sand blasting pot 43 after compression, so that the sand material in the sand blasting pot 43 is pressurized, so that the high-speed air flows into the diversion chamber 51 from the sand blasting tube 44, and then sprayed out from the multiple nozzles 563 along the hose 564 to sandblast the surface of the workpiece. The sprayed sand material leaks into the collection tank provided in the sand blasting chamber 11 through the through holes on the surface of the conveyor belt 21. After the single-sided sand blasting is completed, the flip plate 632 is rotated under the action of the second motor 631 and the third motor 637. While the workpiece is turned over, the first gear 636 drives the flip rack 635 to move.Thus, the support plate 634 slides along the limit block 633, so that the upper support plate 634 before flipping is changed to the lower support plate 634 supporting the workpiece, and the position of the upper support plate 634 before flipping is offset to avoid blocking the sandblasting, so that it can sandblast both sides of the workpiece.
