[0024] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] like Figures 1 to 5 As shown, an automated crucible mixer in one embodiment of this application includes a frame 100, on which a mixing mechanism 200 is rotatably connected. The mixing mechanism 200 is driven by a drive motor 110 for mixing. The mixing mechanism 200 includes a conveying device 210 and a pressing and sealing mechanism. The conveying device 210 is used to convey a tray 320 carrying a crucible 310 to the mixing mechanism 200. The pressing and sealing mechanism is used to press and seal the crucible 310. A protective cover 120 is provided on the frame 100, and the protective cover 120 has an opening 121 for the tray 320 to enter and exit.

[0026] Through this embodiment, the conveying device 210 can be connected to the existing production line and directly convey the tray 320 to the mixing mechanism 200, where it is pressed and sealed by the pressing and sealing mechanism to prevent the contents from spilling out during the mixing process; the drive motor 110 drives the entire mixing mechanism 200 to work together to complete the mixing operation.

[0027] The protective cover 120 is a frame made of profiles and shielded with transparent materials such as plexiglass to facilitate observation of the internal operating status. The plexiglass is used to form a door / window structure, which can be opened for easy maintenance.

[0028] In one embodiment of this application, the two sides of the mixing mechanism 200 are rotatably connected to the frame 100 via rotating shafts 202, and the drive motor 110 drives the mixing mechanism 200 to rotate via the rotating shafts 202. The drive motor 110 drives the mixing mechanism 200 to rotate as a whole, eliminating the need for the tray 320 to be moved again, making the structure of the entire mixing mechanism 200 simpler and easier to operate; it also avoids problems such as the crucible 310 spilling due to excessive movements or frequent transfers.

[0029] In one embodiment of this application, the conveying device 210 is fixed to the frame 201 of the mixing mechanism, and the conveying device 210 is a roller conveyor. The roller conveyor can provide good support for the tray 320, making it convenient for the pressing and sealing mechanism to fix the crucible 310 and the tray 320 together to the conveying device 210, avoiding them being thrown out during the rotation and mixing process; moreover, the roller conveyor provides stable conveying and is suitable for high-precision operations.

[0030] In one embodiment of this application, a positioning mechanism 211 is provided on the roller conveyor. The positioning mechanism 211 includes a positioning cylinder, which is fixed to the frame 201 and can extend through the gap of the roller conveyor. When the tray 320 runs into the mixing mechanism 200, the positioning cylinder at the front extends to stop it from continuing to be conveyed. A positioning cylinder can also be provided at the rear of the tray 320, which together extend to fix the tray 320 and prevent it from being thrown out during rotation. Moreover, this method can fix the tray 320 to the middle part of the mixing mechanism 200, avoid vibration caused by the center of gravity shifting during rotation, and improve the stability of the device operation.

[0031] In one embodiment of this application, the pressing and sealing mechanism includes a pressing cover 220 and a film covering mechanism 230. The film covering mechanism 230 is used to cover the crucible 310 with a film 234. Under the action of the pressing cylinder 222, the pressing cover 220 presses the film 234 onto the crucible 310, thereby sealing the opening of the crucible 310. The bottom surface of the pressing cover 220 is flat, and the film 234 is a sealing film used in traditional mixing operations, which can fit into the opening of the crucible 310 to achieve a seal.

[0032] In one embodiment of this application, the coating mechanism 230 includes a drive roller 231 and a driven roller 232. The drive roller 231 and the driven roller 232 are respectively located on both sides of the conveying device 210. The drive roller 231 is controlled to rotate by a servo motor 233. The film 234 is mounted on the driven roller and tightened by the drive roller 231. A roll of film 234 is mounted on the driven roller 232, and one end of the film 234 is wound around the drive roller 231. The rotation of the drive roller 231 can pull out the film 234, ensuring that the film 234 in the sealed crucible 310 is clean and free of foreign matter each time, thereby improving the test accuracy.

[0033] The drive roller 231 can also help to tighten the film 234, prevent it from curling and folding and causing gaps, ensure the reliability of the seal, and prevent the contents from falling out of the gaps during the rotation and shaking process.

[0034] The servo motor 233 can control the number of rotations of the drive roller 231, thereby ensuring that the film 234 can move a sufficient distance so that the new film 234 can cover the surface of the crucible 310.

[0035] In one embodiment of this application, a brake is provided on the driven roller 232, and an encoder is installed at the shaft 202 of the drive roller 231. The encoder is used to detect the number of rotations of the drive roller 231. The brake is, for example, a magnetic powder brake or an electromagnetic brake, which can control the driven roller 232 to stop rotating, thereby providing a certain tension force to ensure that the film 234 is laid flat on the surface of the crucible 310 and sealed and pressed by the pressing cover 220.

[0036] The encoder is connected to the shaft of the driven roller. During rotation, the encoder collects pulses and determines the number of rotations based on the number of pulses.

[0037] In one embodiment of this application, the driven roller 232 and the drive roller 231 are connected to the frame 201 at both ends via quick-release bearings. For example, quick-release bearings are provided at the upper and lower ends of the bearing, and the base 2341 is connected to the top fixed seat 2342 via quick-release bolts 2343, pressing the bearing into the cavity formed by the base 2341 and the fixed seat 2342, facilitating the replacement of the film roll.

[0038] In one embodiment of this application, the clamping cover 220 includes a cover body 221 and a clamping cylinder 222. The cover body 221 is located above the conveying device 210 and the film 234. The clamping cylinder 222 drives the cover body 221 to press the film 234 onto the crucible 310. The clamping cylinder 222 is a pneumatic cylinder or a servo electric cylinder, capable of driving the clamping cover 220 to move toward or away from the tray 320 to achieve clamping or releasing. When the clamping cover 220 is lifted, the crucible 310 and the tray 320 can move freely in and out, and the film 234, located above the crucible 310, can also be freely conveyed. When the tray 320 reaches the designated position, the film 234 is replaced with a brand new film 234 by rotation, and the clamping cover 220 presses down to press the film 234 onto the crucible 310.

[0039] In one embodiment of this application, a light rod 223 is provided at the bottom of each of the four corners of the cover 221. The light rod 223 is slidably connected to the frame 201. The pressing cylinder 222 is fixed to the bottom surface of the frame 201. The pressing cylinder 222 is fixedly connected to the four light rods 223 through a drive frame 224. The four corners of the drive frame 224 are fixed to the light rods 223, and the middle position of the drive frame 224 is fixed to the cylinder body of the pressing cylinder 222. The piston rod of the pressing cylinder 222 is connected to the bottom surface of the frame 201. When the pressing cylinder 222 is activated, the piston rod pulls the cylinder body up and down, thereby driving the drive frame 224 and the light rods 223 to move up and down, realizing the pressing and upward movement of the cover 221.

[0040] The position of the clamping cylinder 222 can lower the center of gravity of the entire mixing mechanism 200, making it more stable during rotation and reducing the damage of vibration to the whole.

[0041] Furthermore, the pressure cylinder 222's position at the bottom reduces the space protruding from the top, preventing interference and collision with the frame 100 during rotation. It also avoids excessive centrifugal force caused by being too far from the rotating shaft 202, which could affect the normal operation and service life of the pressure cylinder 222.

[0042] According to one embodiment of this application, the beneficial effect of using this automated crucible mixer is that it can directly receive the tray containing the crucible that is conveyed, and after automated coating and pressing, the mixing mechanism is started to mix it. This device has a high degree of automation and can be arranged in existing automated production lines to effectively improve production efficiency.
