[0019] To make the purpose, technical solutions, and advantages of the present application clearer, the following will clearly and completely describe the technical solutions of the present application in combination with specific embodiments and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0020] As Figure 1 shown, the flux automatic filling machine in an embodiment of the present application includes a discharging mechanism 100 and a filling mechanism 200, where: The discharging mechanism 100 is arranged above the filling mechanism 200 and includes a hanging rack 120 for hanging the material bag 101 and a discharging hopper 110, and the discharging hopper 110 is located on one side of the top of the filling mechanism 200; The dispensing mechanism 200 includes an installation flat plate 210, a dispensing funnel 220, and a number of cartridges 310. The cartridges 310 are installed at the bottom of the installation flat plate 210 and flush with the surface of the installation flat plate 210. The distribution of the cartridges 310 is consistent with the material level of the crucible tray. A switching mechanism 330 is provided on the cartridge 310 to close or open the bottom opening of the cartridge 310. The dispensing funnel 220 can slide back and forth on the installation flat plate 210 under the drive of the drive mechanism 230 to add materials to the cartridges 310. A guiding frame 400 is provided below the dispensing mechanism 200. The guiding frame 400 is used to guide the crucible tray transfer rack.

[0021] The dispensing mechanism 200 is installed in a dust-proof cover. A dust suction fan is provided on the dust-proof cover. The dust suction fan can suck away the smoke and dust during the discharging process, avoid dust explosion, and improve safety.

[0022] Through the solution of this embodiment, when in use, place the crucible tray at the bottom of the installation flat plate 210 and make the crucibles correspond to the cartridges 310 one by one. The crucible tray is placed on the crucible tray transfer rack. When the transfer rack moves into the guiding frame 400, it reaches the designated position under the guiding action of the guiding frame, locks the transfer rack, and supports the crucible tray against the bottom of the cartridge 310.

[0023] After the flux in the sachet 101 is added to the discharging hopper 110, it falls from the discharging hopper 110 into the dispensing funnel 220 at the bottom. The dispensing funnel 220 moves to the top of each cartridge 310 under the drive of the drive mechanism 230, drops the flux into the cartridge 310, and moves back and forth to ensure that the flux in each cartridge 310 is filled; the volume of the cartridge 310 can be set to the volume of the required flux. After the cartridge 310 is filled with the flux, open the switching mechanism 330 to make the flux fall into the crucible below to complete the dispensing.

[0024] The installation flat plate 210 in this embodiment is a smooth iron plate. The bottom discharge port of the dispensing funnel 220 abuts against the iron plate and will not leak at the place without the cartridge 310, and can only leak at the place of the cartridge 310.

[0025] In an embodiment of the present application, the installation flat plate 210 is fixed to the installation frame 10, the drive mechanism 230 is fixed to the installation frame 10. The drive mechanism 230 includes a servo motor and a drive chain. The dispensing funnel 220 is slidably connected to the installation frame 10 and connected to the drive chain. The servo motor drives the drive chain to move back and forth. Slide rails are provided on both sides of the installation frame 10. The two ends of the dispensing funnel 220 are slidably connected to the slide rails. Sprockets are respectively provided at the front and rear ends of the slide rails. The two ends of the chain are respectively wound around the sprockets and then connected to the dispensing funnel 220. The servo motor drives one of the sprockets to rotate, thereby realizing the forward and backward movement of the dispensing funnel 220.

[0026] When in use, the dispensing funnel 220 is controlled to move back and forth several times to ensure that all barrels 310 are filled and scraped flat.

[0027] In one embodiment of the present application, the width of the filling funnel 220 is consistent with the width of the mounting plate 210, and an auger is provided in the filling funnel 220. The auger can stir the flux in the filling funnel 220 to avoid blockage during the material leakage process; and the flux can be evenly distributed during the forward and reverse rotation of the auger to ensure that each barrel 310 can be filled.

[0028] In one embodiment of the present application, an adjustment mechanism 300 is also included, and the adjustment mechanism 300 includes an adjustment disk 320, and the four corners of the adjustment disk 320 are supported on the mounting frame 10 through a servo electric cylinder 340. The barrel 310 is a telescopic barrel, and the bottom of the barrel 310 is connected to the adjustment disk 320, and the top of the barrel 310 is fixed to the mounting plate 210. After the adjustment disk 320 rises, the telescopic barrel is squeezed to reduce its volume, and the adjustment disk 320 descends to open the telescopic barrel to increase its volume. In this way, different volumes can be adjusted for crucibles of different specifications, thereby improving the scope of application of the device.

[0029] During adjustment, the four servo electric cylinders 340 act synchronously to adjust the rising or falling distance as needed to improve accuracy.

[0030] In one embodiment of the present application, the switch mechanism 330 is fixed to the adjustment disk 320, and the switch mechanism 330 includes a switch plate 332 and a switch cylinder 331. The switch plate 332 is provided with a material leakage port corresponding to the barrel 310, and the switch cylinder 331 drives the switch plate 332 to move so that the material leakage port overlaps or staggers with the barrel 310. During the process of filling the barrel 310, the switch cylinder 331 moves to completely stagger the material leakage port on the switch plate 332 with the barrel 310, so as to complete the blocking of the bottom opening of the barrel 310. When the filling is completed and needs to be transferred to the crucible, the switch cylinder 331 moves to completely overlap the material leakage port with the bottom opening of the barrel 310, thereby opening the barrel 310 to allow the flux to leak into the crucible.

[0031] In one embodiment of the present application, the adjustment disk 320 includes an upper adjustment disk 321 and a lower adjustment disk 322, and the upper adjustment disk 321 and the lower adjustment disk 322 are fixedly connected by a fixing block 323 with a gap left therebetween. The barrel 310 includes an adjustment barrel 311 and a loading barrel 312 which is mounted on the bottom of the adjustment barrel 311. The loading barrel 312 is fixed to the upper adjustment disk 321, and the top of the adjustment barrel 311 is fixed to the mounting plate 210. The switch plate 332 is slidably connected between the upper adjustment disk 321 and the lower adjustment disk 322.

[0032] During the up and down movement of the adjustment disc 320, it can drive the loading cylinder 312 at the bottom to move upward, thereby compressing the space enclosed by the loading cylinder 312 and the adjustment cylinder 311, realizing the adjustment of the volume of the cylinder 310.

[0033] The fixing blocks 323 are located around the adjustment disc 320 and can fix the upper adjustment disc 321 and the lower adjustment disc 322, leaving a gap in the middle to facilitate the sliding of the switch plate 332 therein. The lower adjustment disc 322 serves as a support to ensure that the switch plate 332 closely adheres to the upper adjustment disc 321, which helps improve the sealing effect of the bottom opening of the cylinder 310 and avoid material leakage caused by the natural drooping of the switch plate 332. Moreover, this solution can also guide the movement of the switch plate 332 to ensure accurate closing and opening.

[0034] The switch cylinder 331 is fixed to the lower adjustment disc 322, and the end of the switch plate 332 extends out of the gap and is fixedly connected to the piston rod of the switch cylinder 331.

[0035] In an embodiment of the present application, guiding cylinders 324 corresponding to the cylinders 310 one by one are provided on the lower adjustment disc 322, and the guiding cylinders 324 are used to dock with the crucibles. When the crucible tray reaches the bottom of the dispensing mechanism 200, it is convenient to observe, so that the crucible can be accurately aligned with the guiding cylinders 324, and the guiding cylinders 324 can enter the crucibles to ensure the accuracy of material discharging and avoid material leakage caused by misalignment.

[0036] In an embodiment of the present application, a plurality of vibration motors 350 are provided on the adjustment disc 320; during the material discharging process, the vibration motors 350 are started to completely shake the flux into the crucibles to avoid affecting the material discharging effect due to blockage. In order to avoid the vibration motors 350 affecting the servo electric cylinder 340, a rubber pad is provided between the servo electric cylinder 340 and the adjustment disc 320.

[0037] A pointer 325 is provided on one side of the adjustment disc 320, and a scale matching the pointer 325 is provided on the mounting bracket 10. The up and down movement of the adjustment disc 320 drives the pointer 325 to move up and down, and the position pointed by the pointer 325 can represent the current volume of the cylinder 310.

[0038] In an embodiment of the present application, extrusion devices are provided on both sides of the hanging bracket 120. The extrusion devices include an extrusion plate 132 and an extrusion cylinder 131. The bottom of the extrusion plate 132 is hinged to the bottom of the hanging bracket 120, and the extrusion cylinder 131 is connected to the middle of the extrusion plate 132 to push the extrusion plate 132 to extrude the material bag 101. During the material discharging process of the material bag 101, it may be blocked due to too small an opening at the bottom. The extrusion cylinder 131 is used to extrude the material bag 101 to facilitate the material to leak into the dispensing funnel 220.

[0039] In an embodiment of the present application, a blocking frame 111 is rotatably connected to the feeding hopper 110. A spring 113 is connected between the blocking frame 111 and the feeding hopper 110. The spring 113 always applies an elastic force to drive the blocking frame 111 to rotate to block the discharging opening at the bottom of the feeding hopper 110. A dial block 112 is provided at the bottom of the blocking frame 111. The movement of the sub-packaging hopper can push the dial block 112 to open the discharging opening.

[0040] A level gauge is provided in the sub-packaging funnel 220. When there is no material left, it will move to the feeding hopper 110. The sub-packaging funnel 220 can abut against the dial block 112 to push the blocking frame 111, causing the blocking frame 111 to rotate and expose the discharging opening to add material to the sub-packaging funnel 220. After the feeding is completed, when the sub-packaging funnel 220 is moved away, the blocking frame 111 will re-block the discharging opening under the action of the spring 113 to prevent the flux from falling.

[0041] In an embodiment of the present application, a brush is installed below the sub-packaging funnel 220. During movement, the brush can sweep the excess flux on the tabletop into the residue buckets at the front and rear bottoms.

[0042] According to an embodiment of the present application, the beneficial effect of adopting this automatic flux dispenser is that it can complete the automatic filling of all crucibles on the crucible tray at one time, and the filling accuracy is high. It can be finely adjusted according to different crucibles, greatly improving the degree of automation.
