Background

The multi-wire cutting machine has high automation degree and low cost, is mainly applied to cutting the material on the material plate into sheet-shaped elements, and mainly cuts the same material. If the sheet-like elements are to be processed into square-shaped elements, a second cut with angular assurance is required, i.e. gluing a plurality of sheet-like elements into a cuboid array sheet package and performing a precise cut of a second knife on the array sheet package.

Currently, cutting is mainly performed by typing using an inner circle slicer. If a multi-wire cutting process is used for the array sheet assembly, a tooling fixture is required to ensure the angles in the other two directions. For example, patent document CN216634951U discloses a crystal array multi-wire cutting jig comprising a base plate, a resin plate fixed above the base plate; a cutting slit, a jig and the like are provided above the resin plate, and a crystal to be cut is placed above the jig perpendicularly to the cutting slit, and is cut along the cutting slit.

Although the position of the crystal is limited, when the crystal is cut to an element array of the crystal, metal, glass, ceramic material and the like, the edge skin (material slag) of the cuboid object is extremely easy to fall off and brought into the grooved wheel under the huge flushing of cutting fluid, so that the breakage rate is greatly improved, and the wire cutting efficiency is greatly influenced.

Referring to fig. 1 to 4, according to an embodiment of the present application, an array tile assembly 500 is a multi-wire cutting jig, including a cutting deck 100, a positioning fence 200, and a baffle 300. The dicing sheet 100 is used to carry the array sheet assembly 500; the number of the positioning backup plates 200 is two, and the positioning backup plates 200 are respectively positioned at two sides of the cutting material plate 100 in the width direction and extend along the length direction of the cutting material plate 100. And the supporting surface 110 of the cutting material plate 100 is perpendicular to the side surfaces of the two positioning backup plates 200, which are close to each other. Meanwhile, the positioning backup plate 200 is located at the end face of the side where the supporting surface 110 of the cutting material plate 100 is located, and a plurality of cutting grooves 210 are sequentially arranged along the length direction of the positioning backup plate 200, and the groove depth direction of the cutting grooves 210 is the cutting direction of the cutting lines. At this time, the plurality of sequentially arranged cutting grooves 210 are in a comb-tooth structure, and the space between every two adjacent cutting grooves 210 is adapted to the groove distance of the roller groove. The supporting surface 110 of the cut material plate 100 is an end surface of the cut material plate 100 that contacts the array sheet assembly 500 when the array sheet assembly 500 is carried. In addition, in the present embodiment, the number of the baffles 300 is two, and the baffles 300 are respectively disposed on the sides of the two positioning backup plates 200 away from each other, and the dimension of the baffles 300 in the height direction of the positioning backup plates 200 is greater than the depth of the cutting groove 210.

In this embodiment, the supporting surface 110 of the cutting plate 100 is perpendicular to the side surfaces of the two positioning plates 200, so that the array sheet assembly 500 is tightly adhered to the positioning plates 200 and glued to the supporting surface 110 of the cutting plate 100, so that the processing verticality of the array sheet assembly 500 can be ensured, and the cutting line is perpendicular to the sheet elements in the array sheet assembly 500, thereby precisely cutting out the required square elements and improving the product yield.

In addition, this embodiment has still set up baffle 300 in the side that two location backup plates 200 kept away from each other, and this baffle 300 is greater than the groove depth size of cutting groove 210 in the size of location backup plate 200 in the direction of height, can cover and shelter from cutting groove 210 completely to stop impurity such as the material skin that drops in the cutting process, material sediment, prevent impurity and get into the roller sheave with rivers and damage the cutting line, can reduce the breakage rate of cutting line, need not the line of changing more than once, effectively solved broken string difficult problem, and then reduce cost consumption and improve cutting efficiency.

It should be noted that, in this embodiment, the improvement is based on the tooling fixture for cutting the rectangular parallelepiped array sheet assembly 500 to form a plurality of square elements, so that the supporting surface 110 of the cutting plate 100 is perpendicular to the side surfaces of the two positioning plates 200 that are close to each other. In actual production, the included angle between the supporting surface 110 of the cutting material plate 100 and the side surfaces of the two positioning backup plates 200, which are close to each other, is not necessarily 90 ° included angle, and can be flexibly set according to the actual processing conditions of the elements, so as to ensure that the elements with other angle sections can also realize accurate cutting, which is not limited herein, and is within the scope of the application.

Specifically, referring to fig. 1 to 3, the cutting board 100, the positioning backup board 200 and the baffle 300 are all rectangular plate structures, and at this time, if the supporting surface 110 of the cutting board 100 is perpendicular to the side surfaces of the two positioning backup boards 200, the cutting board 100 and the positioning backup boards 200 are placed and fixed vertically.

In particular, referring to fig. 1 and 2, the array tile assembly 500 multi-wire cutting jig further includes a base plate 400 to which the cutting deck 100 is directly secured. Meanwhile, the bottom plate 400 is further provided with a positioning slot 410 for installing the positioning back plate 200.

In this embodiment, the cutting board 100 is preferably made of glass, ceramic or resin, and the user needs to fixedly connect the cutting board 100 with the base plate 400, and then grind the cutting surface of the cutting board 100 to ensure that the cutting board 100 and the base plate 400 after the fixed connection meet the surface flatness requirement, thereby ensuring the vertical angle of the array sheet assembly 500 on the cutting board 100 in the height direction of the cutting board 100. If the user grinds the cut material plate 100 first, it cannot be ensured that the connected cut material plate 100 and the base plate 400 still meet the surface flatness requirement after the cut material plate 100 is fixed on the base plate 400, and the re-grinding is highly likely to be required, and the operation steps are complicated and tedious. In addition, the parallelism of the two positioning backup plates 200 should also reach more than one level of standard; meanwhile, the depth direction of the positioning groove 410 is perpendicular to the bottom plate 400 and the moving direction of the wire mesh, so that the array sheet assembly 500 can be closely attached to the positioning backup plate 200, and accurate cutting is realized.

Because the cutting material plate 100 is a consumable, the cutting scratch of the cutting line is easily left on the cutting surface after long-time use, so that the surface planeness requirement of the cutting material plate is affected to a certain extent, and the cutting accuracy is further affected, therefore, in a specific embodiment, the base plate 400 and the cutting material plate 100 are bonded together through glue, and the glue adopts glue which can be degummed, so that the user can conveniently replace the cutting material plate 100.

In addition, the baffle 300 is also a consumable material, and is made of glass, ceramic or resin plate, etc., and can be adhered to the positioning backup plate 200 by using glue capable of degumming. At this time, a gap should exist between the baffle 300 and the bottom plate 400 in the height direction of the positioning backup plate 200, so as to prevent the glue from flowing to the bottom plate 400 along the positioning backup plate 200 when the baffle 300 is fixed on the positioning backup plate 200 by the glue, fix the bottom plate 400 and the baffle 300, and increase the disassembling difficulty and disassembling time of the baffle 300.

In actual production, when a user changes the roller, the cutting plate 100 and the baffle 300 need to be changed together, so that stable operation of the multi-wire cutting fixture of the array sheet assembly 500 is ensured. Meanwhile, since the cutting groove 210 on the positioning backup plate 200 is matched with the roller groove, the positioning backup plate 200 is not required to be replaced together when the roller is replaced, and can be reused.

It should be noted that, referring to fig. 2, the distance between the end surface of the baffle 300 near the bottom plate 400 and the bottom plate 400 should be smaller than the distance between the bottom of the cutting groove 210 and the bottom plate 400, i.e., the end surface of the baffle 300 near the bottom plate 400 should be located below the bottom of the cutting groove 210 in the height direction of the positioning backup plate 200, so as to ensure that the area below the cutting groove 210 is blocked by the baffle 300. If the gap between the baffle 300 and the bottom plate 400 is too large in the height direction of the positioning backup plate 200, so that the area below the cutting groove 210 is not completely blocked by the baffle 300, slag can also enter the roller grooved pulley along with water flow to cause the cutting line to be broken; in addition, the gap between the baffle 300 and the bottom plate 400 is too large, so that the contact area between the baffle 300 and the positioning backup plate 200 can be reduced to a certain extent, the bonding strength of the baffle 300 and the positioning backup plate 200 is affected, the baffle 300 is easy to fall off from the positioning backup plate 200 under the impact of water flow, and a good slag blocking effect is difficult to play.

In contrast, referring to fig. 2, an end surface of the baffle 300 away from the bottom plate 400 should be higher than an end surface of the positioning backup plate 200 away from the bottom plate 400, and at the same time, be higher than the array sheet assembly 500 placed on the cutting material plate 100, so that impurities such as material skin and material slag splashed during cutting can be blocked, the breakage rate of the cutting line is further reduced, and the practicability is strong.

Specifically, referring to fig. 2, the dimension of the baffle 300 in the height direction of the positioning fence 200 is greater than the sum of the height dimension of the cutting fence 100 and the height dimension of the array tile assembly 500. For convenience of description, let the height of the cutting board 100 be H1, the height of the array tile assembly 500 be H2, and the height of the baffle 300 be H3, then H3> h1+h2.

In one embodiment, the dimension of the baffle 300 in the height direction of the positioning fence 200 is at least 1-5mm greater than the sum of the height dimension of the cutting fence 100 and the height dimension of the array tile assembly 500, i.e., H3+.H2+H2+1-5 mm; meanwhile, the width of the barrier 300 is 2-10mm.

In contrast, referring to fig. 1 and 2, an end surface of the positioning fence 200 away from the bottom plate 400 is spaced from the supporting surface 110 of the cutting board 100 by a distance not less than 2/3 of the height dimension of the array tile assembly 500. For convenience of description, let the depth of the positioning groove 410 be H4, and the height of the positioning backup plate 200 be H5, so that H5 is equal to or greater than h4+h1+2/3×h2s.

In this embodiment, the height h5 of the positioning backup plate 200 is equal to or greater than h4+h1+2/3×h2, so, when the array sheet assembly 500 is located on the cutting plate 100, the end of the positioning backup plate 200, which is far away from the bottom plate 400, can reach 2/3 of the position of the array sheet assembly 500 in the height direction, so that the array sheet assembly 500 is convenient to cling to the positioning backup plate 200, and simultaneously, each sheet element in the array sheet assembly 500 clinging to the positioning backup plate 200 is ensured to be parallel to the positioning backup plate 200, so that the operation is convenient, the required square element can be cut more accurately, and the product yield is improved.

In one embodiment, referring to fig. 2, the distance between the bottom of the cutting groove 210 and the bottom plate 400 is smaller than the distance between the supporting surface 110 of the cutting board 100 and the bottom plate 400, i.e., the bottom of the cutting groove 210 is located below the supporting surface 110 of the cutting board 100 in the height direction of the positioning backup board 200.

Because during the cutting process, impurities such as partially fallen material skins and material residues enter the cutting groove 210 and are deposited at the bottom of the cutting groove 210, but in general, the groove width of the cutting groove 210 in the length direction of the positioning backup plate 200 is 0.5-1mm, which is difficult to clean, and the impurities in the cutting groove 210 can take more time and effort to clean one by one, a certain space is reserved for the cutting groove 210 to accommodate the impurities such as partially fallen material skins and material residues during the cutting process. Meanwhile, since the cutting groove 210 is in a comb-tooth structure, and the two positioning backup plates 200 are only provided with the baffle 300 at the side far away from each other, after the impurities contained in the cutting groove 210 are accumulated to a certain extent, the redundant parts can be discharged from the side far away from the baffle 300 of the cutting groove 210, so that the subsequent cutting is not affected, and the cutting line is ensured to be actually cut to the bottom of the array sheet assembly 500 every time.

Specifically, the distance between the bottom of the cutting groove 210 and the supporting surface 110 of the cutting board 100 is 3-6mm, and the groove depth of the cutting groove 210 is H6, so that h6=h5-h4-h1+3-6 mm. If the bottom of the cutting groove 210 is flush with the supporting surface 110 of the cutting plate 100, or the distance between the bottom of the cutting groove 210 and the supporting surface 110 of the cutting plate 100 is relatively short, the cutting line is inevitably affected by impurities at the bottom of the cutting groove 210 when the cutting line is cut next time, so that the cutting line cannot completely cut the array sheet assembly 500, even is broken, and the working efficiency and the product yield are affected.

In one embodiment, referring to fig. 2, a gap exists between the cutting deck 100 and the positioning fence 200 in the width direction, and the dimension of the gap in the width direction may be about 0.5-2 mm.

In this embodiment, the impurities discharged from the side of the cutting groove 210 away from the baffle 300 will enter the gap and will not fall onto the supporting surface 110 of the cutting board 100 to affect the flatness of the cutting board 100. Meanwhile, foreign substances such as chips generated by cutting on the cutting board 100 may be cleaned to the gap between the cutting board 100 and the positioning fence 200. So, the user just need not cut at every turn and all clear up this array sheet subassembly 500 multi-wire cutting anchor clamps, but wait that this array sheet subassembly 500 multi-wire cutting anchor clamps use after, will cut the impurity in the clearance between flitch 100 and the location backup plate 200 again and clear up out together, clean more conveniently, swiftly, still can not influence cutting efficiency, the practicality is strong. In addition, the clearance between the cutting material plate 100 and the positioning backup plate 200 is also beneficial to the gluing of the cuboid array sheet assembly 500, and the structural arrangement is more reasonable.

In one embodiment, the slot width of the positioning slot 410 is greater than the width of the positioning fence 200, such that the positioning fence 200 has a certain distance of movement in the width direction. Specifically, the positioning groove 410 has a groove depth of 5-15mm and a groove width of 0.3-2mm.

Specifically, the bottom of the positioning groove 410 is provided with a fastening hole, and a fastening piece passes through the fastening hole from one side of the bottom plate 400 away from the cutting board 100 to fixedly connect the positioning backup plate 200 and the bottom plate 400.

Wherein, the fastening hole is preferably a countersunk screw hole, and the fastening piece is a countersunk screw. Of course, in actual production, the fastening member may be a bolt, a rivet, or the like, and the shape of the fastening hole may be flexibly set according to the actual fastening member, which is not limited herein, and is within the scope of the present application.

In the foregoing embodiments, the descriptions of the embodiments are focused on, and the parts of a certain embodiment that are not described or depicted in detail may be referred to in the related descriptions of other embodiments.

It should be noted that the above embodiments can be freely combined as needed. The foregoing is merely a preferred embodiment of the present application and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present application, which are intended to be comprehended within the scope of the present application.
