For a product which needs to be subjected to die cutting on the material belt and then subjected to slitting, the advancing direction of the product material belt needs to be strictly controlled, otherwise, the distance between products obtained by die cutting is inconsistent, and the precision processing requirement is not met. In order to position the material belt, in the prior art, positioning holes with the same distance are usually machined in the material belt, and the positioning holes are used for positioning the material belt and a product die-cutting rule, so that the machined product is positioned accurately. For example, chinese patent CN 109794990 a discloses a die cutting process with die cutting positioning holes reserved, which is to set the die cutting positioning holes at the beginning of die cutting and always reserve the die cutting positioning holes by cutting during the die cutting process, so as to ensure that the product is always positioned during the processing process and ensure the processing precision of the product.
Generally, the processing flow of the product is punching and waste discharge, some asymmetric products have requirements on punching directions, the punching directions do not cause waste discharge difficulty, and as for the double-sided adhesive tape product in fig. 1, it cannot be judged from which direction punching is beneficial to subsequent waste discharge before punching; after the cutting die has been made, the cutting die can only be punched along one direction, if the specific work effect of the waste discharge process is found, the waste discharge is not easy to occur in the punching direction of the current cutting die, because the positioning mechanism on the cutter and the product cutting die are made and cannot be changed, the material belt after punching is finished can only be firstly rolled and then discharged, but the method not only increases the rolling process, the material is easy to be sticky back, the outer frame waste material and the product can be sticky back after rolling, the waste discharge is difficult, and the sheets are easy to fall.
Disclosure of Invention
The present invention is directed to overcoming the above-mentioned drawbacks of the prior art and providing a bi-directional positioning etching cutting die.
The purpose of the invention can be realized by the following technical scheme:
a bidirectional positioning etching cutting die comprises a cutting die upper plate and a cutting die lower plate, wherein a product die cutter is arranged on the cutting die upper plate, a material belt to be punched is arranged between the cutting die upper plate and the cutting die lower plate, a positioning mechanism is further arranged on the cutting die upper plate, and the positioning mechanism comprises a first punching die cutter, a positioning guide pillar and a second punching die cutter which are sequentially arranged at the same interval along the feeding direction of the material belt to be punched; the lower plate of the cutting die is provided with a positioning opening matched with the positioning guide pillar; the lower plate of the cutting die is provided with an avoidance step at the position corresponding to the first punching die cutter; the first punching die-cutting knife or the second punching die-cutting knife punches a hole structure on the material belt to be punched; in the positioning and punching processes of the material belt to be punched, a punched hole structure is used as a positioning hole to align to a positioning opening on the lower plate of the cutting die, and a positioning guide pillar of the upper plate of the cutting die penetrates through the positioning hole to enter the positioning opening; and the second punching die-cutting rule punches and cuts the material belt to be punched to obtain a new hole structure.
The positioning process is completed through the positioning guide post and the punching die-cutting knife, the punching die-cutting knife and the positioning guide post are additionally arranged on the upper plate of the cutting die, the punching die-cutting knife is used for punching a material belt to be punched to obtain a hole structure, the hole structure is used as a positioning hole to position the next punching position of the material belt, the newly punched hole structure is aligned to the positioning opening of the lower plate of the cutting die, and the positioning guide post of the upper plate of the cutting die corresponds to the positioning opening, so that the punching position spacing of the product die-cutting knife on the material belt in the two adjacent punching processes is kept consistent, and the spacing is actually the spacing between the punching die-cutting knife and the positioning guide post.
On the basis of completing the positioning function, the invention can realize that the etching cutting die can die cut products in two directions by arranging two punching die-cutting cutters, namely the first punching die-cutting cutter and the second punching die-cutting cutter, and matching with the avoidance step of the cutting die lower plate, and in the using process, if the existing punching direction is not easy to discharge waste, the upper plate of the cutting die can be rotated by 180 degrees to change the positions of the first punching die-cutting cutter and the second punching die-cutting cutter, thereby realizing the change of the direction of the products punched on the material belt to be punched and facilitating the waste discharge.
Two positioning guide columns in the positioning mechanism are respectively a first positioning guide column and a second positioning guide column; the first punching die-cutting rule, the first positioning guide pillar, the second positioning guide pillar and the second punching die-cutting rule are arranged at equal intervals.
Two positioning guide columns are arranged in each positioning mechanism, and during positioning, the two positioning guide columns are inserted into the positioning openings, so that the positioning effect and the accuracy degree are improved.
The height of the upward convex step of the avoidance step is at least 1 mm.
The function of dodging the step is when dodging the punching die cutter of step top and being used in waiting to die-cut material area, can not die-cut material area, avoids the die-cut material area of repetition.
The width direction of the material belt to be punched is taken as a symmetry axis, and the product die-cutting rule is of an asymmetric structure.
The wafer in the hole structure on the material belt to be punched is connected with the main body of the material belt to be punched through a connecting strip; the punching die-cutting knife comprises a hole structure die-cutting knife matched with the hole structure in shape and size and a connecting strip die-cutting knife matched with the connecting strip in shape and size.
Because the hole structures obtained by punching and cutting the material belt by the punching and die-cutting tool are only used as positioning structures, the material belt materials (namely wafers) in the hole structures are not required to be discharged as waste materials, and the process is increased because the waste materials in the discharge holes are additionally provided with the process; therefore, the circular sheets punched by the punching die cutter on the material belt to be punched are not cut off from the material belt main body, but are kept connected with the material belt main body through a connecting strip, so that the circular sheets in the holes are kept connected on the material belt along with the advance of the material belt, waste materials are not generated, the waste discharge problem is not involved, and the process is simplified. In the use process, the positioning guide post moves downwards, the wafer in the hole structure on the material belt is poked into the positioning opening, and the wafer and the connecting strip are attached to the inner wall of the positioning opening because the wafer is connected with the material belt main body through the connecting strip; after die cutting is completed, the positioning guide post is withdrawn from the positioning opening, the material belt moves forwards, the wafer is pulled out from the positioning opening, and the wafer moves forwards along with the material belt.
The axial direction of the connecting strip die cutter is vertical to the feeding direction of the material strip to be punched.
The axial direction of the connecting strip die-cutting knife is parallel to the feeding direction of the material strip to be punched, and the hole structure die-cutting knives of the first punching die-cutting knife and the second punching die-cutting knife are both far away from the positioning guide pillar.
Because the thickness of the sheet material is strictly ensured in the transportation and subsequent processing processes of the sheet material, the direction of the circular sheet obtained by punching relative to the connecting strip is opposite to the feeding direction of the material belt to be punched, and the arrangement is such that when the material belt moves forwards, the circular sheet generated by punching of the punching die cutter and the connecting strip structure can just return to the hollow position on the material belt main body instead of overlapping with the material belt main body, so that the local position on the material belt is thickened, and the next processing is influenced.
The width of the connecting strip obtained by punching is smaller than that of the wafer, and the circle center of the wafer is positioned in the axial direction of the connecting strip; and punching the connecting strip and the main body joint of the material belt to be punched to obtain a widened structure.
The structure is widened in the setting, can guarantee the stable connection of connecting strip in the material area main part, can not take place to drop with the material area main part, causes the production waste material, influences processing.
The positioning mechanisms are respectively arranged at the two sides of the upper plate of the cutting die to position the two sides of the material belt to be punched; the product die-cutting rule is arranged between the two positioning mechanisms.
The positioning opening is a through hole or a cylindrical deep groove.
Compared with the prior art, the invention has the following advantages:
(1) the invention realizes the bidirectional punching of the cutting die, changes the mode that the original scheme can only punch in the same direction, and reduces the waiting time and cost of repeated die opening;
(2) in the die cutting process, the cutting die is simultaneously processed with a hole structure to position the punching of the next group of products, so that the distance between two adjacent groups of products is strictly kept consistent, and the positioning precision is high;
(3) the positioning is convenient, the waste discharge of the wafer material in the positioning hole is not needed, the working procedures are reduced, the processing efficiency is improved, and the cost is saved;
(4) the direction of the circular sheet and the connecting strip generated by the punching die-cutting rule is designed to be opposite to the feeding direction of the material belt, and when the material belt advances, the circular sheet and the connecting strip are just recombined with the hollow structure generated by punching, so that the consistency of the thickness of the material belt is ensured.
