In specific implementation, the feeding station is adaptively arranged according to the specific situation of the production line. The specific position of the stacker platform 31 is set according to the site layout. The support 30 is provided according to the position of the stacker platform 31. Other structures are mounted in corresponding positions by brackets 30. The technical scheme of the application can be more flexibly applied to various scenes.

The stirring synchronous belt 24 is fixedly connected with a stirring push plate 19; the material pushing plate 19 is vertical to the stacking platform 31 from top to bottom, and the distance between the lowest end of the material pushing plate 19 and the stacking platform 31 is smaller than the thickness of one chip 29 to be processed, so that all the chips to be processed can be pushed; the output shaft of the material stirring driving motor 20 is connected with a material stirring main synchronous wheel 23-1.
The stirring synchronous belt 24 is in a shape of a Chinese character kou, and one edge is positioned above the feeding station and the material taking station at the same time; chips 29 to be processed are stacked and placed on the stacker platform 31 between the loading station and the unloading station. As shown in fig. 6 to 7, the rotation direction of the notch-shaped stirring synchronous belt 24 includes two paths: chip loading path 19-1 and kick-out push plate return path 19-2.

The weight sensor 13 is provided on the elevating platform 10. After each group of chips to be processed is pushed onto the lifting platform 10, the material stirring driving motor 20 stops rotating and waits for a next starting signal. After all the stacks are fed, the workers manually feed the space of the chip stacks. Therefore, one-time feeding of a plurality of groups of stockpiles is realized, the number of manual material changing times, namely the material changing time, is reduced, and the feeding efficiency is greatly improved.

Wherein, the elevation structure includes: a weight sensor 13, a conveying motor 7, a guide rod 8, a lifting screw 16 and a horizontal synchronizing wheel 14; through holes are formed in the lifting platform 10 along the periphery, and the number of the through holes is greater than or equal to 4, so that the lifting platform can be stably lifted. The through holes are respectively provided with a nut structure 15 which is in threaded connection with the lifting screw rod 16 and is connected with the guide rod 8 through the linear bearing 9; the guide rod 8 and the lifting screw rod 16 are arranged at intervals. Each lifting screw rod 16 is provided with a horizontal synchronizing wheel 14 respectively, and all the horizontal synchronizing wheels 14 are connected with each other through a horizontal synchronizing belt 12; the output shaft of the transmission motor 7 is coaxially connected with one of the lifting screw rods 16.

The three lifting screw rods 16 are mutually connected through the horizontal synchronizing wheel 14 and the horizontal synchronizing belt 12.
After the weight sensor 13 arranged on the lifting platform 10 detects that the chip is pushed onto the lifting platform, the conveying motor 7 is started to drive the lifting screw rods 16 connected with the output shafts of the conveying motor to rotate, and the three lifting screw rods 16 synchronously rotate based on the horizontal synchronous wheels 14 and the horizontal synchronous belt 12 to drive the lifting platform 10 to lift upwards until the preset sucker structure is stopped after the material is taken to the height.
Since the initial working position of the lift platform 10 is fixed, its distance from the pick-up location of the top suction cup structure is also fixed. Before the conveying motor 7 is started, the lifting height distance H of the lifting platform needs to be calculated, and the specific calculation method comprises the following steps:

During the lifting process, the top contact sensor 25 is arranged at the topmost position allowed to be formed on the lifting platform 10, so that the lifting platform is prevented from exceeding the allowed travel due to misjudgment of a program or manual no operation. When all chips on the lifting platform 10 are sucked away, the lifting platform 10 starts to descend until the lifting platform 10 contacts the contact sensor 25, a signal is generated to indicate that the lifting platform 10 is positioned at the loading position, the material shifting driving motor 20 receives a starting signal, and the material shifting pushing plate 19 is driven to advance forward by one chip storage position for one time according to a preset distance for loading.

When the chip to be processed is sucked up, the sucking disc driving motor 1 is reversed and carries the sucking disc fixing plate 5 to do rising motion, so that the whole chip is sucked up.
