Referring now to fig. 1 to 8, various embodiments of the wire cutting machine of the present utility model will be described with reference to three specific examples.

Example 1

First, embodiment 1 of the present utility model will be described with reference to fig. 1 to 4.

As shown in fig. 1 and 2, in the present embodiment, the wire cutting machine includes a cutting assembly 1, a take-up and pay-off assembly 2, and a feed assembly 3. The cutting assembly 1 includes a cutting frame 11 and a plurality of wire roller mechanisms 12, each of the plurality of wire roller mechanisms 12 being disposed on the cutting frame 11. Each wire roller mechanism 12 comprises a plurality of main roller assemblies 121 arranged on the cutting frame 11, and the cutting wires 4 are wound on the main roller assemblies 121 to form a wire net with a cutting station. Preferably, the wire roller mechanisms 12 are provided in two in this embodiment, with the two wire roller mechanisms 12 being disposed side by side in the space formed by the cutting frame. Each wire roller mechanism 12 further comprises two main roller assemblies 121, and the two main roller assemblies 121 are arranged side by side in the horizontal direction. After the arrangement, four main roller assemblies 121 of the two wire roller mechanisms 12 are horizontally arranged on the cutting frame 11 in a straight line, the cutting wires 4 are respectively wound on the two wire roller mechanisms 12, namely, after the cutting wires 4 are wound on the two main roller assemblies 121 of the first wire roller mechanism 12 in a reciprocating manner to form a wire net of the first wire roller mechanism 12, the wire net enters the two main roller assemblies 121 of the second wire roller mechanism 12 in a reciprocating manner, and then the wire net of the second wire roller mechanism 12 is formed, namely, two wire nets with cutting stations are formed. Each main roller assembly 121 specifically includes a main roller motor, two bearing housings, a wire roller positioned between the two bearing housings, and the like. The two bearing boxes are connected to the cutting frame 11, the wire roller is rotatably arranged between the two bearing boxes, the main roller motor is in transmission connection with one of the bearings, and the specific connection and arrangement modes of the components are conventional means in the field and are not repeated.

Thus, the two wire roller mechanisms 12 respectively form a cutting station, so that two pieces 5 to be cut can be cut simultaneously in one machining process, the cutting efficiency is improved, and the production cost is reduced.

Of course, the arrangement of the cutting assembly 1 is not limited thereto, and a person skilled in the art can adjust it without departing from the principles of the present utility model, so that the present utility model can be applied to more specific application scenarios. For example, the number and arrangement of the wire roller mechanisms 12 are not constant, but three, four or more may be provided instead of two, and the two wire roller mechanisms 12 may be arranged in a vertical direction, or may be arranged obliquely or the like in addition to the horizontal arrangement. As another example, the number and arrangement of the main roller assemblies 121 in each wire roller mechanism 12 is not exclusive, and although two are illustrated in the drawings, it is obvious that one skilled in the art can adjust them, for example, to three, four or more. Taking three main roller assemblies 121 as an example, the three main roller assemblies 121 may be arranged in an inverted triangle. In addition to the above-described horizontal arrangement of the two main roller assemblies 121, the arrangement may be inclined or vertical, and the feeding direction of the feeding assembly 3 will be changed accordingly in the vertical arrangement.

With continued reference to fig. 1 and 2, the feed assembly 3 includes a feed mechanism 31 and a clamping mechanism 32, the feed mechanism 31 being movably disposed on the cutting frame 11, the clamping mechanism 32 being disposed at one end of the feed mechanism 31, the clamping mechanism 32 being provided with a plurality of mounting locations. Specifically, in this embodiment, the feeding mechanism 31 includes a feeding box and a driving assembly, the driving assembly further includes a driving motor and a transmission component, the driving motor is fixedly connected to the cutting frame 11 and is connected to the feeding box through the transmission component, the feeding box is configured to be liftable, and the specific configuration of the feeding mechanism 31 is common in the art, which is not repeated in the present utility model. The clamping mechanism 32 is arranged at one end of the feeding mechanism 31 close to the wire roller mechanism 12, and a plurality of mounting positions are arranged on the clamping mechanism 32 and are used for mounting the piece 5 to be cut. Preferably, the clamping mechanism 32 is provided with two mounting positions, each of which can mount one piece 5 to be cut, and each piece 5 to be cut can correspond to one wire roller mechanism 12. When mounted, the feeding direction of the feeding mechanism 31 is the vertical direction. The specific form of the mounting position is not limited in the present utility model, as long as it can effectively mount the workpiece 5 to be cut. For example, the mounting position can be a chute, a limit lacing wire, a plane with a through hole or a threaded hole, a clamping assembly with a lifting chuck, and the like. Accordingly, the workpiece 5 to be cut may be directly adhered to the mounting position, or may be mounted on the mounting position by a mounting member such as the wafer carrier 34. The wafer support 34 is usually provided with a workpiece plate, on which a backing plate (resin plate, plastic plate, glass plate, etc.) is bonded, and the workpiece 5 to be cut is bonded on the backing plate.

Thus, two pieces 5 to be cut can be simultaneously installed on one clamping mechanism 32, the two pieces 5 to be cut can be simultaneously cut through one feeding action of the feeding mechanism 31 in one machining process, the cutting efficiency is improved, and the equipment structure is simplified.

Of course, the manner in which the feed assembly 3 is provided is not exclusive and can be adjusted as desired by those skilled in the art without departing from the principles of the present utility model. For example, the feeding mechanism 31 and the clamping mechanism 32 may be integrally formed, thereby forming a plurality of mounting positions at the bottom of the feeding mechanism 31. For another example, the number of mounting positions on the holding mechanism 32 is not fixed, but may be three, four or more, as long as the number corresponds to the number of wire roller mechanisms 12.

Referring to fig. 1-4, the take-up and pay-off assembly 2 includes a take-up and pay-off assembly 21 and a transition assembly 22. The winding and unwinding line assemblies 21 are provided with two in the embodiment, and each winding and unwinding line assembly 21 includes a winding and unwinding line roller 211, a first guide wheel 212 and a first tension mechanism 213, and the winding and unwinding line roller 211, the first guide wheel 212 and the first tension mechanism 213 are all disposed on the cutting frame 11. Wherein two first guide wheels 212 are provided, and the two first guide wheels 212 are located upstream and downstream of the first tension mechanism 213, respectively. Preferably, the first tension mechanism 213 selects a linear tension mechanism, the tension wheel of which is moved linearly to achieve tension adjustment of the cutting line 4. Of the two first guide wheels 212, the first guide wheel 212 located between the first tension mechanism 213 and the wire roller mechanism 12 is movably arranged, by means of which movement the wire length of the cutting wire 4 on the wire roller mechanism 12, i.e. the wire web size, can be adjusted.

The transition assembly 22 is arranged on the cutting frame 11 and between two adjacent wire roller mechanisms 12, and the cutting wire 4 is wound around one wire roller mechanism 12 and then wound around the other wire roller mechanism 12 after passing through the transition assembly 22. Specifically, the transition assembly 22 includes a second guide wheel 221 and a second tension mechanism 222, and the second guide wheel 221 and the second tension mechanism 222 are both disposed on the cutting frame 11. Wherein, the second guiding wheels 221 are provided with two, and the two second guiding wheels 221 are respectively positioned at the upstream and downstream of the second tension mechanism 222. Referring to fig. 3 and 4, preferably, the two second guide wheels 221 are disposed side by side in a radial direction of the main roller assembly 121 (i.e., the second guide wheel 221 on the left side in fig. 3 is located on the upper left side of the second guide wheel 221 on the right side), and the two second guide wheels 221 are movably disposed in an axial direction of the main roller assembly 121 (the two second guide wheels 221 are movable left and right by guide rails in fig. 4), and the second tension mechanism 222 is a linear tension mechanism located on one side of the two second guide wheels 221 in the axial direction of the main roller assembly 121 (the left side of the two second guide wheels 221 in fig. 4) and movable in the axial direction of the main roller assembly 121. In this way, the winding length of the cutting line 4 can be adjusted by adjusting the positions of the two second guide wheels 221, and the tension can be adjusted by adjusting the positions of the tension wheels of the linear tension mechanism.

As can be seen from fig. 3 and 4, after winding one wire roller mechanism 12, the cutting wire 4 passes through one second guide wheel 221 and then enters the second tension mechanism 222, then enters the other second guide wheel 221 through the second tension mechanism 222, and finally is discharged to the other wire roller mechanism 12 for winding through the second guide wheel 221.

By providing the transition assembly 22, the influence between adjacent cutting stations in the cutting process is reduced, and the cutting stability of each cutting station is improved. By disposing the second tension mechanism 222 on one side of the two second guide wheels 221 in the axial direction of the main roller assembly 121, the interval between two adjacent wire roller mechanisms 12 can be reduced, thereby saving space and reducing the occupation of equipment space. The two second guide wheels 221 are arranged in the axial direction of the line roller mechanism 12 in a movable way, so that the position of the cutting line 4 can be adjusted by adjusting the positions of the second guide wheels 221 when the wire is broken, and the wire connection difficulty of the wire net is reduced.

Of course, the arrangement of the take-up and pay-off assembly 2 is not limited, and in other application scenarios, one skilled in the art can adjust it based on the requirements. For example, while the above-described take-up and pay-off assembly 2 is described in connection with including the take-up and pay-off assembly 21 and the transition assembly 22, the provision of the transition assembly 22 is merely preferred and may be optionally omitted by those skilled in the art. As another example, the specific composition of the take-up and pay-off assembly 21 is not exclusive, and in other embodiments, a person skilled in the art may adjust the number of the first guide wheels 212 and the first tension mechanisms 213 in the take-up and pay-off assembly 21, such as setting the first guide wheels 212 as one, or omitting the first tension mechanisms 213, etc. Alternatively, the arrangement of the two take-up and pay-off assemblies 21 may be the same or different. As another example, the slidable arrangement of the first guide wheel 212 and the second guide wheel 221 is merely preferable, and those skilled in the art can arrange them in a fixed or adjustable gear form based on the need. For another example, the specific composition of the transition assembly 22 is not limited, and one skilled in the art may adjust the combination thereof, for example, a portion of the second guide wheel 221 or the second tension mechanism 222 may be omitted. For another example, although the first tension mechanism 213 and the second tension mechanism 222 are described as linear tension mechanisms, this is not a constant, and one or both of the first tension mechanism 213 and the second tension mechanism 222 may be replaced with a swing tension mechanism. For another example, the positional relationship between the two second guide wheels 221 and the second tension mechanism 222 is merely preferable, and those skilled in the art may set the two second guide wheels without referring to the above-mentioned scheme, which may cause an increase in the space occupied by the apparatus.

Example 2

Embodiment 2 of the present utility model will be described with reference to fig. 5 and 6.

As shown in fig. 5 and 6, the main difference between this embodiment and embodiment 1 is that the feeding assembly 3 further includes a balance mechanism 33, and the balance mechanism 33 is provided on the cutting frame 11 and connected to the holding mechanism 32 for preventing the holding mechanism 32 from descending under the dead weight. Specifically, in the present embodiment, two balance mechanisms 33 are provided, and the two balance mechanisms 33 are arranged on both sides of the feeding mechanism 31 and connected to the holding mechanisms 32 on both sides of the feeding mechanism 31. The balancing mechanism 33 is a cylinder, a hydraulic cylinder or an electric cylinder. Taking a cylinder as an example, the cylinder body of the cylinder is fixedly connected with the cutting frame 11, and the piston of the cylinder is connected with the clamping mechanism 32.

In this way, in the process of feeding the feeding mechanism 31 downwards, the cylinder can provide an upward pulling force to balance the weight of the workpiece 5 to be cut and the clamping mechanism 32, so that the stress of the feeding mechanism 31 in the feeding direction is reduced, the descending stability of the clamping mechanism 32 is improved, and the processing quality is improved.

Further, the clamping mechanism 32 in this embodiment further comprises a connecting section 321 and a plurality of clamping sections 322 detachably connected to each other, wherein the connecting section 321 is connected to the feeding mechanism 31, one mounting position is provided on each clamping section 322, and each clamping section 322 is connected to one balancing mechanism 33. Specifically, the clamping mechanism 32 in this embodiment includes a connecting section 321 and two clamping sections 322, where the two clamping sections 322 are separately arranged on two sides of the connecting section 321 and detachably connected to the connecting section 321, and each clamping section 322 is further connected to a balancing cylinder. The present utility model is not limited to the specific form of the detachable connection, and for example, the clamping section 322 and the connecting section 321 may be partially stacked and then be detachably connected by a bolt and nut assembly, or a snap claw may be provided between the clamping section 322 and the connecting section 321 to detachably connect the two, etc.

Thus, in the feeding process, the two clamping sections 322 are locked with the connecting section 321, the whole clamping mechanism 32 is stably moved downwards under the action of the balance cylinder, and the bending of the two ends of the clamping mechanism 32 is avoided. When the wire is broken, the connection between the clamping section 322 and the connecting section 321 at the wire breaking side can be loosened, the balance mechanism 33 at the wire breaking side is controlled to lift the clamping section 322 together with the piece 5 to be cut, then the wire is connected to the wire breaking position, and after the wire connection is completed, the balance mechanism 33 is controlled to drive the clamping section 322 and the piece 5 to be cut to descend to the position before the wire breaking, and the clamping section 322 and the connecting section 321 are locked.

By arranging the plurality of clamping sections 322, the independent control of the balancing mechanism 33 on the clamping sections 322 is facilitated, for example, when the cutting line 4 is broken, the clamping mechanism 32 is not required to be lifted integrally, and broken line reconnection can be realized only by lifting the clamping sections 322 on the broken line side through the balancing mechanism 33, so that the processing quality of the unbroken line side is facilitated to be improved, and the maintenance difficulty is reduced.

Those skilled in the art will appreciate that the arrangement of the balancing mechanism 33 and the clamping mechanism 32 is not exclusive and that those skilled in the art can adjust the arrangement based on the specific application. For example, the balance mechanism 33 may not be provided, the number thereof may be changed, and one, three, or more may be provided. The balancing mechanism 33 may be symmetrically disposed or asymmetrically disposed, which is of course more advantageous for improving the stability of the clamping mechanism 32. For another example, although the above-described clamping mechanism 32 is described in connection with one connecting section 321 and two clamping sections 322, it is only preferable that the number of clamping sections 322 can be increased or decreased in other embodiments, and when the number of clamping sections 322 is greater, adjacent clamping sections 322 can be detachably connected. Of course, it is also possible to connect the feeding mechanism 31 with one of the clamping sections 322 instead of the connecting section 321 by connecting a plurality of clamping sections 322 side by side. Furthermore, the arrangement of the balancing mechanism 33 and the arrangement of the clamping mechanism 32 comprising multiple segments need not be simultaneously satisfied, and one of them may be omitted selectively by a person skilled in the art.

Example 3

Next, embodiment 3 of the present utility model will be described with reference to fig. 7 and 8.

As shown in fig. 7 and 8, the main difference between this embodiment and embodiment 2 is that at least one main roller assembly 121 among the plurality of main roller assemblies 121 is adjustably disposed to the cutting frame 11 in the radial direction thereof. Specifically, in the present embodiment, all of the main roller assemblies 121 are provided to be radially adjustable. Preferably, the main roller assembly 121 is radially adjustable by means of the eccentric sleeve 13. Specifically, the cutting assembly 1 further includes an eccentric sleeve 13, the eccentric sleeve 13 having an eccentric hole, the eccentric sleeve 13 being mounted on the cutting frame 11, and two bearing housings of the main roller assembly 121 being respectively mounted in the eccentric hole of one eccentric sleeve 13, thereby achieving adjustable mounting of the two bearing housings, i.e., radial adjustment of the main roller assembly 121. In this setting mode, when the position of the main roller assembly 121 needs to be adjusted, only the angle of the eccentric sleeve 13 needs to be rotated, and the position of the main roller assembly 121 along the radial direction is changed, so that the distance between the main roller assemblies 121 can be adjusted, the width of the wire mesh is further changed, and the wire mesh is suitable for pieces to be cut with different sizes. For a specific principle of adjusting the main roller assembly 121 by the eccentric sleeve 13, reference is made to patent publication CN212471990U (the adjusting principle of the eccentric bearing housing described below is similar).

So, through setting up main roll subassembly 121 along its radial adjustable, for example adjust the interval between the main roll subassembly 121 through setting up eccentric sleeve 13, can realize the processing technology of multiple different line main roll intervals, different cutting angles through adjusting the position of main roll subassembly 121 to promote the suitability of wire cut electrical discharge machining to the piece 5 of waiting of multiple specification, practice thrift equipment acquisition cost. Meanwhile, when the cutting angle is inclined, the liquid carrying capacity of the cutting liquid can be improved, so that the cooling effect of the cutting liquid and the effect of carrying out cutting scraps are better, and the slicing quality is finally improved.

Further, when the workpiece 5 to be cut is mounted in the mounting position by the crystal support 34, a workpiece plate for bonding the workpiece 5 to be cut is provided on the crystal support 34, and the bonding surface of the workpiece plate is an inclined surface.

In this way, the bonding surface of the workpiece plate is an inclined surface, the backing plate is bonded on the workpiece plate, after the workpiece 5 to be cut is bonded on the backing plate, the workpiece 5 to be cut is inclined, and the main roller assembly 121 is matched to adjust the inclination to be the same, so that the bottom surface of the workpiece 5 to be cut is kept parallel to the wire mesh under the condition that the feeding mechanism 31 is kept to feed vertically, and the cutting quality is improved. In addition, compared with the scheme of directly obliquely arranging the feeding mechanism 31, the arrangement mode does not need to change the existing feeding mechanism 31, saves equipment cost and has higher processing quality.

It will be appreciated by those skilled in the art that the foregoing arrangement is merely preferred and is not intended to limit the scope of the utility model, as modifications may be made to the above-described embodiments by those skilled in the art without departing from the principles of the utility model.

For example, in the above embodiment, the arrangement of the main roller assembly 121 that is radially adjustable and the workpiece plate bonding surface is set to be a slope is not necessarily satisfied at the same time, and one skilled in the art may selectively omit one or all of them.

For another example, the position adjustment of the main roller assembly 121 may also be achieved by means of an eccentric bearing housing. Specifically, the main roller assembly 121 includes two eccentric bearing housings, and a wire roller disposed between the two eccentric bearing housings, both ends of the wire roller being respectively connected to one eccentric bearing housing, the two eccentric bearing housings being respectively installed in one installation hole of the cutting frame 11. By rotating the bearing housing, the position between the wire rolls can be adjusted. In addition, the mounting hole on the cutting frame 11 may be a waist hole to adjust the position of the main roller assembly 121, and the adjusting manner may refer to the patent with the publication number CN207522877U, which is not described in detail herein.

In an alternative embodiment, in order to incline the workpiece 5 to be cut after being bonded, the bonding surface of the backing plate may be an inclined surface instead of modifying the wafer support 34.

In another alternative embodiment, tilting of the piece 5 to be cut can also be achieved by providing a swinging mechanism. Specifically, the feeding assembly 3 further includes a swinging mechanism connected to the mounting position, the swinging mechanism being capable of swinging with respect to the mounting position, and one end of the swinging mechanism being used for connecting the piece 5 to be cut. For example, the swing mechanism is a rack and pinion swing mechanism, a gear pulley swing mechanism, or a gear chain swing mechanism. One end of the swinging mechanism is fixedly connected with the clamping section 322, the other end of the swinging mechanism can swing relatively, when the piece 5 to be cut is fed, the swinging mechanism can be firstly made to swing to a horizontal state, then the crystal support 34 is arranged at one end of the swinging mechanism, then the swinging mechanism is controlled to swing to a position where the bottom surface of the piece 5 to be cut is parallel to the wire mesh, and then cutting is started.

Therefore, the swinging mechanism is added, so that the to-be-cut piece 5 can hover at any angle, thereby being more suitable for different wire mesh cutting angles, being beneficial to realizing different cutting modes of different cutting stations, realizing oblique cutting of an inclined wire mesh and horizontal cutting of a horizontal wire mesh simultaneously, realizing multiple purposes, and greatly reducing the processing cost. Meanwhile, the arrangement of the swinging mechanism is also beneficial to reducing the loading and unloading difficulty of the piece 5 to be cut, and horizontal loading and unloading can be realized by adjusting the swinging mechanism during loading and unloading.

Of course, it will be understood by those skilled in the art that, although embodiment 3 is modified from embodiment 2, this is not intended to limit the scope of the present utility model, and the balance mechanism 33 may be omitted and the clamping mechanism 32 may be integrally formed without being split into the connecting section 321 and the clamping section 322, while the main roller assembly 121 is used to radially adjust and the bonding surface of the workpiece plate is obliquely disposed.

Those skilled in the art will appreciate that while some embodiments described herein include some features but not others included in other embodiments, combinations of features of different embodiments are meant to be within the scope of the utility model and form different embodiments. For example, in the claims of the present utility model, any of the claimed embodiments may be used in any combination.

Thus far, the technical solution of the present utility model has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present utility model is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present utility model, and such modifications and substitutions will fall within the scope of the present utility model.
