This not only has low production efficiency and high labor intensity, but also the plastic bags used in the process are disposable, resulting in a large amount of waste of resources and costs.

[0019] The following further describes the embodiments of the present utility model in more detail with reference to the drawings and reference numerals, so that those skilled in the art can implement it after studying this specification. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] The present utility model provides a Figures 1-5 shown automatic quantitative silicon material filling device, including a primary feeding unit and a secondary feeding unit.

[0021] Please refer to Figures 1-4, The primary feeding unit includes a frame 11, a turntable 12 rotatably connected to the frame 11, a driving device for driving the turntable 12 to rotate, and a first feeder 13 disposed on the turntable 12. The frame 11 and the turntable 12 are rotatably connected by bearings and bearing seats; the first feeder 13 can be a vibrating feeder, one end of its feeding trough protrudes from the frame 11 and is provided with a discharge port, which is convenient for installing the secondary feeding unit below the discharge port, and a sealing plate 14 is provided at the top of the feeding trough of the first feeder 13. An inlet hopper 15 is provided at one end of the sealing plate 14 away from the discharge port, and silicon material enters the feeding trough of the first feeder 13 from the inlet hopper 15; the driving device can be a motor, and the output shaft of the motor and the rotating shaft of the turntable are in gear transmission to drive the first feeder 13 installed on the turntable 12 to rotate. A plurality of secondary feeding units are sequentially distributed along the circumferential direction of the rotating shaft of the turntable 12, so that the moving trajectory of the discharge port of the first feeder 13 covers a plurality of secondary feeding units, and feeds the plurality of secondary feeding units in turn to achieve continuous operation.

[0022] Please refer to Figure 3 , 5 , The secondary feeding unit includes a lifting platform 21, a weighing module 22 disposed on the lifting platform 21, and a second feeder 23 disposed on the weighing module 22. Since the currently used refeeding cylinder 30 has a certain height, its top opening is the inlet, and the installation site limits the installation height of the primary feeding unit. Therefore, it is necessary to use the lifting platform 21 to change the height of the second feeder 23. When feeding, the lifting platform descends until the feeding trough of the second feeder 23 is lower than the discharge port of the first feeder 13, and when filling, the lifting platform rises until the discharge port of the second feeder 23 is higher than the refeeding cylinder 30. The lifting platform 21 can be a scissor-type lifting platform driven by a telescopic rod or a worm screw lifting platform. The weighing module 22 can refer to related technologies and is used to measure the feeding amount in the feeding trough of the second feeder 23 in real time. When the feeding amount meets the set weight required for filling, the first feeder 13 stops feeding. The second feeder 23 can be an electromagnetic vibrating feeder, one end of its feeding trough protrudes from the lifting platform 21 and is provided with a discharge port for convenient discharging; a plurality of second feeders 23 can be provided on the lifting platform 21 to fill the refeeding cylinder 30 simultaneously, improving production efficiency, and the feeding troughs of the plurality of second feeders are sequentially distributed along the circumferential direction of the turntable rotating shaft.

[0023] The overall working process of this embodiment is as follows: The silicon material enters the feeding trough through the feeding hopper of the first feeder. The driving device drives the turntable to rotate, so that the discharge port of the first feeder rotates above the feeding trough of a certain second feeder, and feeding starts until the feeding amount in the feeding trough of the second feeder reaches the predetermined weight. Then the first feeder stops feeding and rotates above the feeding trough of another second feeder to continue feeding. After all the second feeders of a secondary feeding unit are loaded with the silicon material of the predetermined weight, the lifting platform rises until the discharge port of the second feeder is higher than the refeeding cylinder; the trolley equipped with the refeeding cylinder is pushed under the discharge port of the second feeder. The number and position of the refeeding cylinders on the trolley correspond to the number and position of the second feeders of the secondary feeding unit. The second feeder starts to work and fills all the silicon material into the corresponding refeeding cylinders; after the filling is completed, the refeeding cylinders are pushed away, the lifting platform descends and resets, waiting for the next feeding.

[0024] The above are one or more embodiments of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
