Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the invention and therefore show only the structures which are relevant to the invention.
In a first embodiment, as shown in fig. 1 to 6, the present embodiment provides a substrate feeding mechanism, including: the feeding table top 1 is provided with a plurality of supporting feet below the feeding table top 1, so that the feeding table top 1 is supported up to lift the feeding table top 1 to a height convenient for operators to operate. The feeding table top 1 is provided with a feeding station, and the wafer box can be prevented from being arranged on the feeding station so as to realize subsequent automatic feeding. The magazine is whole rectangular magazine, has a plurality of slot that sets gradually along the direction of height in the magazine inside to the both sides of magazine all are uncovered to set up, in order to make things convenient for the operator to insert inside the magazine with the base plate from one side level, and finally realize a plurality of magazine and laminate the state in proper order.
It should be noted that in the prior art, after the wafer box is usually placed at the loading station, the wafer box is automatically pushed away by other devices, then after the wafer box reaches the plastic packaging station of the specified plastic packaging machine, the corresponding mechanism sequentially takes down the substrate on the wafer box for plastic packaging, after the wafer box is unloaded, an operator can take the wafer box away, and a new fully loaded wafer box is placed at the loading station again for the next working cycle. In the above-mentioned process of placing to plastic packaging, because the base plate needs to be pushed out from the inside of the wafer box in proper order, therefore the circumference of wafer box needs to be in the both sides opening of length direction in order to realize above-mentioned process. However, under the above conditions, the device itself inevitably vibrates during operation, so that the device vibrates to drive the wafer box to vibrate, and the wafer box drives the substrate to vibrate, and the substrate is relatively light, and the two sides of the wafer box are open, so that the substrate may gradually deviate from the wafer box or even slide out of the wafer box during vibration, and as a result, flaws or damages to the substrate may be caused. On the other hand, in the case of producing a substrate, the substrate is subjected to heat treatment in the preceding step, and the substrate subjected to heat treatment is likely to be slightly bent, and the bent substrate can be repaired by the extrusion process, but in this step, the bent substrate may still exist. Therefore, the distance between the slots of the cassette is slightly greater than the thickness of the substrate, so that the substrates can be inserted conveniently, the possibility of vibration falling of the substrates can be increased due to the non-uniform sizes of the slots and the substrates, and meanwhile, if the substrates reach the pick-up position, the curved substrates shift to one side of the pick-up mechanism, the mechanism can be blocked at the parts of the substrate bulge and the cassette, and the substrates cannot be correctly inserted into the corresponding slots, so that the substrates cannot be removed.
In order to solve the above-described problem, in the present embodiment, the positioning mechanism and the sheet-integrating mechanism 3 are designed. Specifically, the whole piece mechanism 3 and the positioning mechanism are respectively arranged at two sides of the feeding station, the back plate is arranged at the outer side of the positioning mechanism, meanwhile, the whole piece mechanism 3 is hinged with the feeding tread, and the opening side of the wafer box faces to the positioning mechanism and the whole piece mechanism 3 respectively. In this embodiment, as a preference, when the operator can operate, the whole sheet mechanism 3 rotates to topple over on the feeding table top 1, at this time, the feeding station is opened, the operator can place the fully loaded sheet box on the feeding station, then the operator rotates the whole sheet mechanism 3 to be vertical, at this time, the whole sheet mechanism 3 can cooperate the backboard to shield the feeding station from two sides, and meanwhile, the movable space in the opening direction of the sheet box is also shielded, at this time, even if equipment vibration exists, the substrate can be effectively protected from falling out of the sheet box. In addition, in order to further ensure that the base plate can not deviate to the whole piece mechanism 3 one side to prevent the condition that follow-up unable piece of getting from appearing, in this embodiment, design positioning mechanism for with the bottom butt of magazine, the top butt with the magazine when whole piece mechanism 3 is vertical put simultaneously, through above-mentioned design, positioning mechanism and whole piece mechanism 3 in both sides respectively with the top and the bottom butt of magazine, and then whole piece mechanism 3 can push the magazine to the backplate one side to the perk. The whole piece mechanism 3 also can be telescopically arranged, after the whole piece mechanism 3 pushes the wafer box to the perk, an operator can further drive the whole piece mechanism 3 to shrink along the height direction, at the moment, the whole piece mechanism 3 intermittently pushes the wafer box to enable the wafer box to shake, and under the state that the wafer box is inclined towards the back plate direction at the moment, the substrate inside the wafer box is continuously close to the back plate direction along with shaking until the substrate is attached to the back plate. Through the mode, the offset direction of the substrate can be controlled, so that the substrate is prevented from being offset towards the direction of the whole sheet mechanism 3, further, each substrate can be smoothly taken down in the follow-up sheet taking process, meanwhile, the substrate and the backboard are in inclined contact, and the substrate and the backboard are in line contact, so that the damage of the backboard to the substrate is small during vibration.
In order to achieve the above effect that the whole wafer mechanism 3 abuts against the wafer cassette and drives the substrate to shake, in this embodiment, as an option, the whole wafer mechanism 3 includes a whole wafer inclined plane 31 disposed toward the wafer cassette, and the whole wafer inclined plane 31 is disposed obliquely in a direction away from the positioning mechanism along a vertically downward direction. Through the arrangement, after the wafer box is placed to the feeding station, the whole wafer inclined plane 31 and the positioning mechanism can be abutted with the wafer box from two sides, and meanwhile, the whole wafer inclined plane 31 can push the wafer box to tilt towards the back plate direction by taking the positioning mechanism as a fulcrum. Meanwhile, a plurality of whole-piece units 32 are arranged on the whole-piece inclined plane 31, the head ends and the tail ends of two adjacent whole-piece units 32 are connected, and the head ends and the tail ends of two adjacent whole-piece units 32 form a folding angle. Through the arrangement, when the whole sheet mechanism 3 contracts along the height direction, the sheet box slides along the whole sheet inclined plane 31 to form a first folding angle position, at this time, along with the continuous descending of the whole sheet mechanism 3, the second whole sheet unit 32 continuously tilts the sheet box along the folding angle direction, the sheet box drives the substrate inside to synchronously move, when the sheet box reaches the second folding angle position, the movement direction of the sheet box suddenly changes, the substrate moves along the original movement direction under the action of inertia, at this time, the condition that the movement of the first substrate and the sheet box is not uniform occurs, namely, the substrate shakes, along with the continuous descending of the whole sheet mechanism 3, the sheet box passes through the plurality of whole sheet units 32 and circulates the process, and the effect that the substrate gradually approaches to the back plate direction can be realized.
The structure of the whole sheet unit 32 is specifically described below, the whole sheet unit 32 includes a straight section 321 and an inclined section, the straight section 321 is consistent with the height direction of the whole sheet mechanism 3, and the intersection of the inclined section and the straight section 321 forms an obtuse included angle, thus forming a bevel. When the wafer box slides to the folding angle along the straight surface section 321, the movement direction of the wafer box is changed because the wafer box can only slide along the inclined surface section, and the substrate in the wafer box can not change the movement direction immediately under the inertia effect, so that the movement direction of the wafer box and the substrate are inconsistent, and the wafer box drives the substrate to shake.
In order to avoid the excessive tilting angle of the cassette along the inclined plane section, in this embodiment, the inclined plane section includes a guiding surface 322 and a transition surface 323, where the guiding surface 322 is connected to the transition surface 323, and the guiding surface 322 and the transition surface 323 are respectively connected to the straight surface sections 321 of two adjacent integral units 32. The angle between the guiding surface 322 and the straight surface section 321 is smaller than the angle between the transition surface 323 and the straight surface section 321, so that a break angle is formed between said guiding surface 322 and said transition surface 323. That is, the connection between the transition surface 323 and the straight surface section 321 is smoother, the guiding surface 322 is used for guiding the wafer box to incline, and the transition surface 323 is used for guiding the wafer box to gradually approach the straight surface section 321, so as to avoid the collision between the substrate and the wafer box caused by overlarge tilting angle of the wafer box.
The structure of the sheet-integrating mechanism 3 is specifically described below, and the sheet-integrating mechanism 3 further includes a hinge plate 33 and a telescoping plate 34. The hinge plate 33 is hinged to the feeding table top 1, the expansion plate 34 is arranged at the top of the hinge plate 33, and the expansion plate 34 is elastically connected with the hinge plate 33. Through the arrangement, an operator can drive the hinged plate 33 and the telescopic plate 34 to rotate around the feeding table top 1 to be horizontal or vertical through the hinged plate 33 so as to open or close the feeding station. Meanwhile, the whole inclined plane 31 is arranged on one side of the expansion plate 34 facing the positioning mechanism, so that when the expansion plate 34 is in a vertical state, the whole inclined plane 31 can be abutted with the top of the wafer box. In addition, the expansion plate 34 is elastically connected to the hinge plate 33, so that an operator can control the effect that the expansion plate 34 is contracted toward the hinge plate 33 or the expansion plate 34 is opened.
In order to achieve the above effect, in this embodiment, optionally, a telescopic slot 331 is formed at the top of the hinge plate 33, and the telescopic plate 34 is disposed in the telescopic slot 331. A plurality of expansion springs 332 are arranged in the expansion grooves 331, and two ends of each expansion spring 332 are respectively connected with the hinge plate 33 and the expansion plate 34. Through the above arrangement, when the hinge plate 33 rotates to the vertical state, the wafer box is grounded to the bottom of the whole wafer inclined plane 31, and then an operator presses the expansion plate 34 along the vertical direction, so that the expansion plate 34 can extrude the expansion spring 332, and then the expansion plate 34 contracts inwards towards the expansion groove 331, so that the whole wafer inclined plane 31 continuously extrudes the wafer box from top to bottom, and each whole wafer unit 32 drives the wafer box and the substrate to shake.
In order to limit the hinge plate 33 and enable the expansion plate 34 to keep a vertical state when being contracted, in this embodiment, a supporting plate 11 is further installed on one side of the feeding table top 1, and the supporting plate 11 is provided with a limiting block 12 towards one side of the expansion plate 34. The top of the expansion plate 34 is provided with a fastening groove 341, and the fastening groove 341 corresponds to the limiting block 12. The limiting block 12 is provided with a magnet, and meanwhile, the corresponding position of the hinge plate 33 is also provided with a magnet, so when an operator rotates the hinge plate 33 to be vertical, the hinge plate 33 can be adsorbed by magnetic force and is tightly attached to one side of the limiting block 12, at the moment, the operator presses the telescopic plate 34, the limiting groove can be inserted into the buckling groove 341, further, the horizontal movement of the telescopic plate 34 is not limited by the limiting block 12, and only the telescopic plate can slide up and down, and through the arrangement, the reliable movement of the telescopic plate 34 can be ensured. In addition, a positioning sensor 13 is provided on the stopper 12. When the hinge plate 33 rotates to be closely attached to the limiting block 12 in a magnetic attraction mode, the positioning sensor 13 receives signals to indicate that the hinge plate 33 is reliably positioned, namely, the feeding station is in a closed state. The positioning mechanism is a positioning guide rail 2, and the positioning guide rail 2 extends along the conveying direction of the wafer box. The positioning guide rail 2 is a strip-shaped protruding block, and is arranged on one side of the backboard to separate the wafer box from the backboard, so that the backboard can tilt by taking the positioning guide rail 2 as a pivot, and meanwhile, the positioning guide rail can be used as a direction guide to ensure the wafer box to move correctly when the subsequent substrate moves.

And one side of the sheet taking mechanism 6 facing the feeding station is provided with a sheet taking station.
