Technical Field

The utility model relates to the technical field of photovoltaic production, in particular to a device for removing fragments in an empty flower basket.

Background

The basket is a carrier in the production process of the silicon wafers, the silicon wafers are firstly loaded in the basket through the inserting machine and then enter the cleaning machine for cleaning, the basket conveys the loaded silicon wafers to the sorting machine after cleaning, and the sorting machine grabs the silicon wafers from the basket and then sends the silicon wafers to the next processing link. And (5) returning the empty basket after the silicon chips are grabbed by the sorting machine to the inserting machine again, reloading the silicon chips and cleaning the silicon chips by a cleaning machine.

Specifically, in the initial state, the spring 250 between one end of the rotating rod 230 and the fixed column 240 is in an original state, i.e. in a state without tension and compression force, the other end (i.e. the extending end) of the rotating rod 230 extends into the space between the rails 120, when the hollow flower basket 400 passes over the platform 100, the U-shaped frame 411 at the inlet end of the hollow flower basket 400 contacts the extending end of the rotating rod 230 and toggles the rotating rod 230 to rotate around the positioning pin 220 in the moving process, one end of the rotating rod 230 rotates in the opposite direction, at this time, the spring between the rotating rod 230 and the fixed column 240 is stretched, when the U-shaped frame 411 at the inlet end of the hollow flower basket 400 moves a certain distance relative to the positioning pin 220, the extending end of the rotating rod 230 is separated from the U-shaped frame 411 at the inlet end of the hollow flower basket 400, at this time, the rotating rod 230 is reset under the action of the spring 250, the extending end of the rotating rod is revolved and extends into the hollow flower basket 400 (i.e. between the other group of the clamping holders 421 and the pair of the supporting rods 422), and the residual fragments on the other group of the clamping holders 421 (i.e. the bottom of the U-shaped frame 421) are removed until the other end of the hollow flower basket 400 contacts the U-shaped frame 411, the extending end of the rotating rod 230 is stretched, and the hollow flower basket 230 is reset, and the hollow flower basket 400 is completely removed after the rotary flower basket 400 is reset, and the hollow and the fragments are removed.

In some embodiments, the first culling component 200 may further include: mount pad, servo driving motor and rotary rod.

Wherein the mounting seats are attached to the outside of the rail 120.

The servo driving motor is arranged on the mounting seat.

One end of the rotating rod is connected with the driving end of the servo driving motor, and the other end of the rotating rod extends between the pair of tracks 120.

The other end of the rotating rod is driven by the servo driving motor to rotate in the horizontal plane, so that when the empty basket 400 passes through, the rotating rod stretches into the space between the other group of clamping holders 421 in the empty basket 400 and the pair of supporting rods 422 to remove residual fragments.

In the body, the difference between the present embodiment and the above embodiment is that the manner of driving the rotating rod 230 is replaced by driving by a servo driving motor, and the servo driving motor is controlled to drive the rotating rod 230 to rotate by detecting the time interval period of the passage of the empty basket (the conventional prior art is omitted here, and detailed description is omitted here), so that the automation degree is good and the control is convenient.

In some embodiments, as shown in fig. 1, the first rejecting assembly 200 may further include a blocking post 260, where the blocking post 260 is disposed on the mounting base 210 and is located on the inner side of the positioning pin 220, and the blocking post 260 abuts against the other end of the rotating rod 230 when the rotating rod 230 is reset.

That is, the retaining post 260 is disposed on the inner side of the positioning pin 220 on the mounting base 210, so as to limit the rotation rod 230 in the initial state, avoid other interference, and ensure the normal and stable removal process.

Preferably, the line of the stopper 260 and the positioning pin 220 is perpendicular to the rail 120.

In some embodiments, as shown in fig. 1, the mounting base 210 is flush with the top surface of the track 120, and the setting height of the rotating rod 230 relative to the mounting base 210 is higher than the setting height of the supporting rod 422 on the U-shaped frame 411 and lower than the setting height of the other set of clamping brackets 421 on the U-shaped frame 411.

Thus, the spin lever 230 of the first reject assembly 200 is ensured to extend reliably and accurately into the interior of the empty basket 400 for debris removal.

In some embodiments, as shown in fig. 1 and 2, the device for removing chips in an empty basket according to the embodiments of the present utility model may further include a second removing assembly 300, where the second removing assembly 300 is disposed between the pair of rails 120, and the second removing assembly 300 is configured to extend from the bottom up into the empty basket 400 passing over the platform 100 to remove chips therein.

That is, the debris removal effect is further enhanced by providing the second reject assembly 300 between the pair of rails 120 to remove debris from the basket 400 in the vertical direction. It should be noted that the second rejecting assembly 300 is disposed at different length positions on the rail 120 relative to the first rejecting assembly 200.

In some embodiments, as shown in fig. 1,2, 5, and 6, the second culling assembly 200 may include: a pair of fixing blocks 310, a connecting shaft 320, and a pair of rotating plates 330.

Wherein, when the empty basket 400 passes through, the top end of the rotating plate 330 is inserted into the space between the bottom of the other group of clamping holders 421 in the empty basket 400 and the outer sides of the pair of supporting rods 422, so as to remove the residual fragments.

Specifically, when the hollow flower basket 400 moves on the track 120, in an initial state, the U-shaped frame 411 at the inlet end of the hollow flower basket 400 is firstly abutted against the top of the rotating plate 330, the top of the rotating plate 330 is forced to rotate downwards around the connecting shaft 320, the bottom of the rotating plate 330 rotates upwards, the hollow flower basket 400 continues to move, after the U-shaped frame 411 at the inlet end of the hollow flower basket 400 passes through the position of the rotating plate 330, the top of the rotating plate 330 is forced to disappear, the rotating plate 330 is rotated downwards to an original state under the gravity action of the bottom balancing weight 340, the top of the rotating plate correspondingly rotates upwards to the original state, and then the rotating plate extends into the hollow flower basket 400 (namely, the space between the bottoms of the bottom clamping brackets 421 of the pair of the U-shaped frames 411 and the outer sides of the pair of the supporting rods 422) to perform a debris removing operation until the U-shaped frame 411 at the other end of the hollow flower basket 400 is abutted against the top of the rotating plate 330, and the top of the rotating plate 330 is forced to rotate to retreat out of the hollow flower basket 400 until the U-shaped frame 411 at the other end of the hollow flower basket 400 passes through the position of the rotating plate 330, and the rotating plate 330 is driven to reset by the balancing weight 340, thereby completing the debris removing process.

In some embodiments, as shown in fig. 1, the upper half of the swivel plate 330 is curved along the direction of travel of the empty basket 400 on the rail 120.

Therefore, the interference of the moving of the empty basket 400 when the rotating plate 330 clears the fragments can be reduced, the empty basket 400 can be conveniently pressed down to pass through the rotating plate 330, and the service life of the rotating plate 330 is prolonged.

While the foregoing is directed to the preferred embodiments of the present utility model, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present utility model, and such modifications and adaptations are intended to be comprehended within the scope of the present utility model.
