Detailed Description
The following description provides many different embodiments, or examples, for implementing different features of the invention. The elements and arrangements described in the following specific examples are presented for purposes of brevity and are provided only as examples and are not intended to limit the invention.
In the related art, the positioning piece is inserted onto the bottom plate first, then the material is placed on the bottom plate, and the positioning piece penetrates through the material on the bottom plate to position the material. After the material is placed, place the apron of folding board platform on the material surface, the locating part passes the apron simultaneously to link together bottom plate, material and apron, be convenient for carry out pressfitting to the material and handle.
However, in the actual stacking process, it is found that part of the positioning members cannot pass through the material to be matched with the cover plate, especially the top layer material close to the cover plate, so that the position of the part of the material may deviate, and the subsequent treatment effect on the material is affected.
The inventor researches that, because the positioning piece is knocked by an operator to be inserted into the bottom plate, the length of the positioning piece inserted into the bottom plate is determined by the knocking force of the operator, and a plurality of positioning pieces are generally required to be inserted into one bottom plate to position materials, so that the knocking force of the plurality of positioning pieces is difficult to be always kept, the lengths of the plurality of positioning pieces inserted into the bottom plate are difficult to be consistent, and the lengths of the plurality of positioning pieces exposed out of the bottom plate are also difficult to be identical. In the process of stacking materials, the material stacking thickness of the positioning piece with the shorter length exposed to the bottom plate is thinner, and under the condition that other positioning pieces penetrate through the materials, the positioning piece with the shorter length exposed to the bottom plate cannot penetrate through the top layer materials, so that the positioning effect of the positioning piece on the materials is poor.
Especially, in the process of stacking and pressing kraft paper involved in the manufacturing process of circuit boards, because the surface of the kraft paper is smoother, when one of the positioning pieces cannot pass through the kraft paper, the kraft paper is more likely to shift.
In view of the above, an embodiment of the present application provides a stacking board for a circuit board, as shown in fig. 1 to 10, by matching the lifting shaft 520 with the power structure 510, the positioning member is driven to move towards the outside of the bottom plate 100, so that the length of the positioning member exposed out of the bottom plate 100 is increased, so as to position a portion of the top material.
The stacking table provided by the embodiment of the application comprises a bottom plate 100, a cover plate 200, a driving assembly 300, a jacking assembly 500 and at least one positioning piece, and is shown with reference to fig. 1. The base plate 100 serves as a platform for placing materials, which are directly placed on the base plate 100 for processing, and the base plate 100 has a plurality of first positioning holes 110. The first positioning holes 110 are positioned at different positions on the bottom plate 100 and are suitable for materials with different specifications and sizes. The cover plate 200 is used for being placed on the surface of a material, and is clamped on two sides of the material with the bottom plate 100 respectively, and the cover plate 200 can press the material. The cover plate 200 is provided with a second positioning hole 210 corresponding to the first positioning hole 110 to position the cover plate 200. The driving assembly 300 is used for connecting the cover plate 200, and driving the cover plate 200 to move. The driving assembly 300 is capable of driving the cover plate 200 to the first position. With the cover plate 200 in the first position, the cover plate 200 is disposed parallel to the base plate 100, and the second positioning holes 210 located at the cover plate 200 are aligned with the corresponding first positioning holes 110, so that the positioning members are simultaneously inserted into the first positioning holes 110 and the second positioning holes 210 to position the cover plate 200 and the base plate 100.
The number of the positioning pieces is at least one, and the specific required number is set according to actual requirements. The positioning piece is inserted into any first positioning hole 110, and the selection of the first positioning hole 110 is determined according to the size specification of the material. In actual operation, the positioning holes are also formed in the material, and the first positioning holes 110 aligned with the positioning holes in the material are selected to be inserted with the positioning pieces, so that the positioning pieces can penetrate through the material to position the material under the condition that the material is placed on the bottom plate 100.
The jacking assemblies 500 and the cover plates 200 at the first position are respectively located at two sides of the bottom plate 100, so that stacking materials of the bottom plate 100 are not affected, and the jacking assemblies are shown in fig. 2. The jacking assembly 500 includes a power structure 510 and a jacking shaft 520 in one-to-one correspondence with the first positioning holes 110, as shown with reference to fig. 3. The power structure 510 is used for driving the plurality of jacking shafts 520 to move along the axial direction thereof, so that the jacking shafts 520 can push the positioning piece inserted in the first positioning hole 110 to move towards the outside of the first positioning hole 110. The jacking assembly 500 and the cover plate 200 at the first position are respectively located at two sides of the bottom plate 100, so that the power structure 510 drives the jacking shaft 520 to push the positioning member to move towards the cover plate 200, and the length of the positioning member exposed to the bottom plate 100 can be increased.
The length of the spacer exposed to the base plate 100 increases and the thickness of the material through which the spacer can pass correspondingly increases. In actual use, even though the material covers the positioning member, by activating the power structure 510, the lifting shaft 520 is driven by the power structure 510 to push the positioning member towards the outside of the first positioning hole 110, so that the positioning member passes through the material covered on the end portion thereof, thereby positioning the material. In the process of stacking and pressing materials by the stacking table, particularly in the case that a plurality of positioning pieces are inserted on the bottom plate 100, the lengths of the positioning pieces exposed on the bottom plate 100 are different in a large probability, and the positions of the positioning pieces can be adjusted through the jacking assembly 500, so that each positioning piece can penetrate through the materials on the top layer and be matched with the cover plate 200, the overall structure of the bottom plate 100, the materials and the cover plate 200 is stable, and the follow-up processing of the materials is facilitated.
In the use process of the stacking platform, firstly, the positioning piece is inserted onto the bottom plate 100, then the materials are stacked on the bottom plate 100, and in the process of stacking the materials, the positioning holes in the materials need to be aligned with the positioning piece, so that the positioning piece penetrates through the materials, after the materials are placed on the bottom plate 100, operators need to observe whether the positioning piece penetrates through all the stacked materials, if the situation that the positioning piece is covered by the materials exists, the power structure 510 needs to be started, and the positioning piece is driven to move towards the outside of the bottom plate 100, so that the positioning piece covered by the materials can penetrate through the materials. Or the power structure 510 is started in advance, so that the situation that the positioning piece is covered by the material is prevented. Then, the driving assembly 300 is started to drive the cover plate 200 to the upper part of the material, and the material is pressed tightly, and the positioning piece passing through the material also passes through the second positioning hole 210 on the cover plate 200 while the cover plate 200 abuts against the material. And then the connection of the driving assembly 300 to the cover plate 200 is released, and the cover plate 200 is knocked to press the materials again. After the lamination is completed, the whole structure of the base plate 100, the material, the cover plate 200 and the positioning member is pushed together towards a conveying belt connected with the lamination table, and then conveyed to the next process. Then, the base plate 100 is replaced, the conveyor belt conveys a new cover plate 200, the driving assembly 300 is connected with the cover plate 200, and then the positioning piece can be inserted onto the base plate 100 to start the processing of a new round of materials.
In particular embodiments, the driving assembly 300 generally includes a magnetic attachment structure 310, a rotating arm 320, and a linkage transmission structure 330, as shown with reference to fig. 1. One end of the rotating arm 320 is connected with the magnetic attraction connecting structure 310, and the other end is connected with the connecting rod transmission structure 330. The magnetic connection structure 310 is connected with the cover plate 200, and the connecting rod transmission structure 330 drives the rotating arm 320 to rotate, so that the cover plate 200 connected with the rotating arm 320 moves in position relative to the bottom plate 100. The magnetic connection structure 310 can be quickly connected with the cover plate 200 or disconnected from the cover plate 200, and the operation is quick and convenient. The link transmission structure 330 has high structural strength and can bear large acting force, and even if the weight of the cover plate 200 is too heavy, the cover plate 200 can still be driven to smoothly rotate.
The number and positions of the jacking shafts 520 are required to be set in one-to-one correspondence with the first positioning holes 110, so that the jacking shafts 520 can drive the positioning members to move no matter which of the first positioning holes 110 the positioning members are inserted into. The second positioning holes 210 on the cover plate 200 do not necessarily correspond to the first positioning holes 110 one by one. The cover plate 200 may be different according to the materials to be processed, and thus, the second positioning holes 210 on the cover plate 200 need only be aligned with one of the first positioning holes 110, and the number of the second positioning holes 210 may be smaller than the number of the first positioning holes 110.
The jacking assembly 500 according to the embodiment of the present application further includes a carrier 530, the jacking shafts 520 are all fixed on the carrier 530, and the power structure 510 is connected to the carrier 530 for driving the carrier 530 and the jacking shafts 520 fixed on the carrier 530 to move, as shown in fig. 3, 4 and 7. All jacking shafts 520 all move with carrier 530 synchronization, therefore, in the in-process of jacking locating pieces of jacking shafts 520, peg graft in the condition that all locating pieces of bottom plate 100 all contacted with jacking shafts 520, jacking shafts 520 can jack locating pieces to same height to unify the high position of a plurality of locating pieces, make a plurality of locating pieces all can stablely peg graft in bottom plate 100, material and apron 200, improve the position stability of material, be convenient for follow-up handling to the material.
The surface of the carrier 530 is slidably provided with a stopper 540, and the stopper 540 can slide toward the jacking shaft 520 to be connected with the jacking shaft 520. In the case that the limiting member 540 is connected to the jacking shaft 520, the limiting member 540 is in limiting fit with the jacking shaft 520 in the axial direction of the jacking shaft 520, so that the position of the jacking shaft 520 is fixed, and in the process that the jacking shaft 520 exits from the first positioning hole 110, the jacking shaft 520 can descend along with the carrier 530 instead of being clamped in the first positioning hole 110, so that the jacking shaft cannot exit.
After the limiting member 540 is connected with the jacking shaft 520, the relative position of the jacking shaft 520 and the carrier 530 is fixed, so that the jacking shaft 520 can move synchronously along with the carrier 530. The limiting member 540 is slidably disposed on the carrier 530, and the connection relationship between the limiting member 540 and the jacking shaft 520 is controlled by the sliding limiting member 540, so as to facilitate operation.
The jacking shaft 520 has a limiting groove 521, and the limiting member 540 can slide into the limiting groove 521 to be in limiting fit with the jacking shaft 520. The limiting groove 521 has various structures. For example, the limiting groove 521 is a groove formed on the circumferential sidewall of the jacking shaft 520, and the limiting member 540 slides toward the jacking shaft 520 to be clamped in the limiting groove 521, so as to complete the limiting fit between the limiting member 540 and the jacking shaft 520. In some preferred embodiments, the limiting groove 521 may be an annular groove disposed on a side wall of the jacking shaft 520, the limiting member 540 has a U-shaped structure, and the limiting member 540 slides to be inserted into the limiting groove 521. In other preferred embodiments, the limiting groove 521 may be an annular groove formed on the side wall of the jacking shaft 520, and the limiting member 540 is provided with a long hole 541 so as to be sleeved outside the jacking shaft 520, and the long hole 541 has a large end and a small end, as shown in fig. 5, by sliding the limiting member 540, the large end of the long hole 541 slides into the limiting groove 521, so that the jacking shaft 520 cannot be limited, the jacking shaft 520 can be replaced or detached, and the small end of the long hole 541 slides into the limiting groove 521, so that the jacking shaft 520 can be limited, and the jacking shaft 520 is prevented from moving axially relative to the stage 530.
