DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-6 An automated high-energy vertical vibration ball mill mixing system comprises a workbench 1, on which a mechanical arm 2, an array plate 3, a vibration ball mill 4, a ball adding mechanism 5 and a capping mechanism 7 are arranged, the mechanical arm 2 is provided with a clamping claw 21, and a grinding jar is placed on the array plate 3; the array plate 3 can select an eight-station array plate to facilitate the positioning and taking of the mechanical arm 2.

[0032] The ball adding mechanism 5 includes a fixed positioning plate 51, a ball outlet assembly arranged above the positioning plate 51, and a material guide tube 55 on the positioning plate 51 connected to the ball outlet assembly. A ball receiving mechanism 6 for placing a grinding jar is provided at the material outlet end of the material guide tube 55; the grinding balls are stored and released by the ball outlet assembly, and the released grinding balls are sent into the grinding jar placed at the ball receiving mechanism 6 through the material guide tube 55.

[0033] The capping mechanism 7 includes a fixing frame 71, a storage frame 72 for placing sealing covers arranged on the fixing frame 71, a cantilever 73 arranged below the fixing frame 71 corresponding to the storage frame 72, and a pushing assembly arranged on the cantilever 73; the sealing covers are stacked in the storage frame 72, the lowest sealing cover falls on the cantilever 73, the sealing cover on the cantilever 73 is pushed out by the pushing assembly, and the lower end of the storage frame 72 is blocked at the same time, after the pushing is completed, the pushing assembly is reset, and the lowest sealing cover of the storage frame 72 falls on the cantilever 73 again to prepare for the next pushing.

[0034] Based on the above technical solution, when the ball milling and mixing system is used, the robot arm 2 is started, and the grinding jar placed on the array plate 3 is moved to the ball receiving mechanism 6 using the clamping claw 21, and then the ball adding mechanism 5 is started to send the grinding balls into the grinding jar through the material guide tube 55. Subsequently, the robot arm 2 cooperates with the clamping claw 21 to place the sealing cover pushed out by the capping mechanism 7 on the grinding jar for sealing. Finally, the robot arm moves the grinding jar to the vibration ball mill 4 for ball milling and mixing. The ball milling is completed and the grinding jar is taken out by the robot arm to complete the discharge. Through the automatic feeding design of the ball adding mechanism 5 and the capping mechanism 7, the materials are combined in cooperation with the robot arm 2 to realize the automatic ball adding and grinding of the grinding and mixing, and improve the automation process of the ball milling and mixing system.

[0035] In this technical solution, if Figure 1-6 As shown, the ball outlet assembly includes a storage tray 52 fixedly mounted on the positioning tray 51, a protective frame 53 arranged outside the storage tray 52, a turntable 54 rotatably mounted on the storage tray 52, and a discharge pipe 521 embedded in the storage tray 52 corresponding to the guide pipe 55, the turntable 54 is provided with a through hole matching the grinding balls, the positioning tray 51 is provided with a stepping motor 541 for driving the turntable 54 to rotate, and the protective frame 53 is fixedly provided with a blocking block 531 corresponding to the discharge pipe 521.

[0036] The grinding balls are collected by the receiving tray 52, and the protective frame 53 is used to prevent the grinding balls from flying out. When the balls need to be discharged, the stepper motor 541 drives the turntable 54 to rotate a certain angle, and one or more grinding balls enter the drop hole for temporary storage. After the grinding balls are collected, the turntable 54 is rotated to reset, so that the drop hole and the discharge pipe 521 are aligned so that the grinding balls are sent into the guide pipe 55 through the discharge pipe 521 to achieve the discharge of the balls. At the same time, the drop hole is also rotated to the stopper block 531, and the abnormal discharge of the grinding balls is prevented by the blocking of the stopper block 531. At the junction of the discharge pipe 521 and the guide pipe 55, a sensor device such as a position sensor can also be set to detect the discharge of the grinding balls, to ensure that the grinding balls can be stably fed into the grinding tank, and to ensure the ball milling effect.

[0037] In this technical solution, if Figure 1-4 As shown, the top wall of the rotating disk 54 is in a cone shape with a high middle and low edges, so that the grinding balls can gather at the edge of the rotating disk 54, ensuring that the grinding balls can smoothly enter the drop holes for collection, and ensuring stable discharge of the grinding balls.

[0038] In this technical solution, if Figure 1-6 As shown, the pusher assembly includes a pusher plate 74 slidingly arranged on the cantilever 73, and a pusher cylinder 75 fixedly installed below the fixed frame 71 to control the sliding of the pusher plate 74. The thickness of the pusher plate 74 matches the sealing cover. The pusher cylinder 75 drives the pusher plate 74 to slide, and the sealing cover placed on the cantilever 73 is pushed out. When pushing out, the pusher plate 74 closes the lower end of the storage frame 72. After the pushing is completed, the pusher plate 74 is reset, and the sealing cover in the storage frame 72 falls again on the front side of the pusher plate 74 to prepare for the next pushing. Stable feeding of the sealing cover is achieved.

[0039] In this technical solution, if Figure 1-6 As shown, sensors 76 for detecting the position of the sealing cover are provided on both sides of the cantilever 73. Through the design of the sensor 76, the pushing position of the sealing cover is detected to ensure that the mechanical arm 2 can stably clamp the sealing cover and ensure stable sealing between the sealing cover and the grinding jar.

[0040] In this technical solution, if Figure 1-4As shown, the ball receiving mechanism 6 includes a vertical rod 61 fixedly arranged below the positioning plate 51, a fixed plate 62 fixedly arranged horizontally on the vertical rod 61, a sliding bracket 63 slidably arranged on the fixed plate 62 for limiting the grinding jar, and a support seat 64 fixedly arranged below the sliding bracket 63 for placing the grinding jar. A horizontal adjustment plate 651 and a vertical adjustment plate 652 for adjusting the position are arranged below the support seat 64. Through the design of the sliding bracket 63, it is convenient to adjust the placement position of the grinding jar. An opening matching the grinding jar can be opened on the sliding bracket 63, and the position of the grinding jar is limited on the side to ensure the stable placement and clamping of the grinding jar by the mechanical arm 2. The position of the support seat 64 is adjusted in coordination with the horizontal adjustment plate 651 and the vertical adjustment plate 652 to match the adjustment of the placement position of the grinding jar by the sliding bracket 63, so as to ensure the stable support and placement of the grinding jar by the support seat 64.

[0041] In this technical solution, if Figure 1-4 As shown, an adjustment bracket 551 for adjusting the discharge position of the guide tube 55 is provided on one side of the fixing plate 62. The curvature of the guide tube 55 is adjusted by adjusting the bracket 551 to adjust the discharge position, so as to ensure that the grinding balls sent out of the guide tube 55 can stably fall into the grinding tank, thereby ensuring a stable ball discharge effect.

[0042] In this technical solution, if Figure 1 and 2 As shown, the vibrating ball mill 4 is provided with a fixing bracket 41 for fixing the grinding jar and a clamping cylinder 42 for pressing the grinding jar. After the grinding balls are placed in the grinding jar and the sealing cover is covered, the grinding jar is sent to the fixing bracket 41 by the mechanical arm 2. The fixing bracket 41 can be provided with a placement hole corresponding to the grinding jar to ensure the stable placement of the grinding jar. After the placement is completed, the clamping cylinder 42 is started to press the sealing cover, and the fixing bracket 41 is cooperated to achieve stable fixation of the grinding jar. After the fixation is completed, the vibrating ball mill 4 is started for vibration grinding. The vibrating ball mill 4 can use a vertical vibration grinder, grind at a frequency of 2000-3000Hz for 2-3min, let it stand for 10s, release the cylinder, use the mechanical arm 2 to take out the grinding jar and put it back into the array plate 3, that is, the grinding of the material is completed, and the automated process of material ball grinding is realized.
