The slicing conveying mechanism, defective material discharge mechanism, cam flipping mechanism and material collection mechanism are arranged in a straight line. The chips sliced ​​by the slicing conveying mechanism are transported to the defective material discharge mechanism for inspection through multiple suction nozzles on a straight line. The chips at the discharge mechanism are transported to the cam flipping mechanism, and the chips at the cam flipping mechanism are transported to the material collection mechanism. The material collection lifting mechanism is located directly below the material collection mechanism.

[0038] Specifically, the chip separation and transfer mechanism realizes chip separation and transfer, and its structure is as follows: Figures 5-6 As shown, it includes a backboard 21, an upper conveying assembly 22 fixed on the backboard, a lower conveying assembly 23, an upper slice assembly 24, a lower slice assembly 25, a drive motor 26 and a separation conveying assembly 27, the upper conveying assembly includes an upper driving wheel 221, an upper tensioning wheel 222, an upper belt 223, and three upper idler wheels 224.

The lower belt is sleeved on the lower driving wheel, the loading pallet and the outside of the multiple lower idler wheels. The lower tensioning wheel is fixed to the back plate by a second cylinder, and the lower tensioning wheel presses against the lower belt from the outside to ensure the tension of the lower belt, thereby ensuring that the lower driving wheel can drive the lower belt to rotate and transmit. The lower driving wheel passes through the back plate, and the end thereof is connected to the driving motor 26 installed on the back plate with a matching gear, and the driving motor controls the rotation of the lower driving wheel;

[0040] The upper belt and the lower belt are arranged opposite to each other with a certain gap between them. The mutual friction and transmission force are used to transmit the chip between the upper belt and the lower belt. When in use, the loading tray is the chip loading end. In order to ensure that the chip will not shift after being placed, feeding guide plates 236 are provided on both sides of the loading tray.

When the chip is not transmitted, the lower roller acts as an ordinary roller, and when the chip is transmitted, the lower roller serves as the bottom support during slicing, and the upper pressure roller applies downward pressure. Due to the eccentric setting of the two, the slicing can be achieved. After slicing, the upper pressure wheel is lifted, and the transmission force of the upper belt and the lower belt transmits the slicing chip backward.

[0042] The separation and conveying assembly includes a mounting bracket 271, a conveying chain 272 wrapped around the outside of the mounting bracket, a cover plate 273 fixed above the mounting bracket for covering part of the conveying chain, a separation cylinder 274 fixed on the cover plate, and a laser detector 275 fixed at the end of the mounting bracket. One end of the mounting bracket is fixed to the side of the back plate, and the end is connected to the lower belt so that the chip conveyed by the lower belt can enter the conveying chain. A baffle 276 is provided at the telescopic end of the separation cylinder. The baffle is used to block the next chip to ensure that the next chip is conveyed after the previous chip is moved. The laser detector is used to detect the quality of the chip after slicing. If it is a defective product, it will be discharged through the defective product discharge mechanism during subsequent transportation.

[0043] The structure of the defective product discharge mechanism is as follows: Figure 7 As shown, it includes a support base 31, a mounting plate 32 fixed above the support base, a slide cylinder 33 fixed above the mounting plate, a carrier mounting plate 34 fixed on the slider of the slide cylinder, and a carrier 35 fixed on the carrier mounting plate.

The rotating servo motor is installed on the flip fixing seat through a motor seat 425 and is connected to the synchronous wheel with a synchronous belt 426. The flip servo motor drives the rotating shaft to rotate, while the cam is fixed. A circle of track grooves 427 is provided on the outer wall of the cam. One section of the track groove is close to one end of the cam, and the track groove on the opposite surface is close to the other end of the cam.

[0045] The rotating bearing assembly includes a rotating plate 431 and a chip positioning bearing seat 432. One end of the chip positioning bearing seat is fixed at the center position of the rotating plate and is vertically connected to it. The other end is provided with a chip placement groove 433.

The sensing assembly includes a U-shaped frame 451 and a photoelectric sensor 452 installed on the U-shaped frame. The end of the rotating plate is installed with a sensing sheet 434. When the sensing sheet blocks the photoelectric sensor, it indicates that the rotation is in place, and the rotating motor is controlled to stop rotating.

[0046] As the rotating shaft rotates, the cam follower at the end of the linkage rod moves along the track groove, and at the same time drives the linkage rod and the L-shaped cover to move telescopically. When the L-shaped cover is located above the chip positioning support seat, it is in a retracted state, exposing the chip placement slot for placing or removing the chip. When the L-shaped cover is located below the chip positioning support seat, it is in an extended state, covering the chip placement slot from below to support the placed chip.

At the same time, a second slot 551 is also provided at the bottom of the magazine clamp, and a support plate 552 is provided inside the magazine clamp. The support plate is connected to the material receiving and lifting mechanism. When the magazine clamp initially receives materials, the support plate is located at the top of the magazine clamp. As the number of chips increases, the support plate gradually descends. When it reaches the bottom, it means that the magazine clamp is full. At this time, the conveying motor drives the conveyor belt and the multi-station magazine clamp seat to move, and moves the empty magazine clamp to the unloading position for unloading, while the full magazine clamp is manually removed.

A pin (not shown) is provided on the part so that the pin can be inserted into the end of the push rod to achieve the connection between the two. A second sensing piece 77 is provided on the side of the sliding plate corresponding to the photoelectric sensor. When the second sensing piece moves to the position corresponding to the top photoelectric sensor, it means that the support plate is at the top of the warehouse clamp. When the second sensing piece moves to the second to last photoelectric sensor below, it means that it is full and needs to be replaced. Then the push rod drops again to the second photoelectric sensor at the bottom. At this time, the upper end of the push rod is separated from the support plate and also leaves the second slot. The multi-station warehouse clamp seat can move the next empty warehouse clamp to the top of the push rod for unloading of the next warehouse clamp.
