Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crystal processing, in particular to a method for connecting broken steel cutting wire of multi-wire cutting equipment. BACKGROUND

[0002] The third generation semiconductor silicon carbide (SiC) has excellent physical and electrical properties (such as high band gap, high thermal conductivity, high breakdown field strength, etc.), and has become an ideal material for high temperature, high pressure and high frequency power devices. However, due to its extremely high hardness (Mohs hardness 9.2-9.3) and brittleness, it faces the risk of wire breakage during multi-wire cutting processing, especially when using thinner steel wire, the problem of wire breakage is particularly prominent. In the process of dealing with multi-wire cutting wire breakage, due to the small diameter of the steel wire and a certain degree of wear, repeated wire breakage often occurs during the wire head connection process, making it difficult to connect the wire, thereby prolonging the equipment downtime and product circulation period, and greatly reducing personnel efficiency.

[0003] Among them, the existing broken wire connection method has the following problems:

[0004] ① Insufficient joint strength: the traditional knotting method is easy to cause secondary breakage due to the inertia force of the guide roller swing arm or the tension fluctuation;

[0005] ② Low connection efficiency: the worn diamond wire is fragile, and repeated wire breakage occurs during connection, with a single connection time of 120-180 minutes;

[0006] ③ High wire walking failure rate: in the existing technology, the scheme of fixing the joint by using cloth-based adhesive tape is prone to cause wire parallel and wire skipping when the connection point is walking in the wire net, and repeated wire cutting and wiring is required, affecting the cutting reference. SUMMARY

[0007] Therefore, the present application provides a method for connecting broken steel cutting wire of multi-wire cutting equipment, which can reduce the probability of wire breakage, improve the reliability of the joint, and shorten the connection time.

DETAILED DESCRIPTION

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The method for splicing broken steel cutting wires in a multi-wire cutting device provided in this embodiment of the invention, such as... Figure 1 As shown, it includes the following steps:

[0040] S1. Connect the wire end of the infeed groove wheel 9 of the multi-wire cutting equipment to the wire end of the wire feeding wheel 7 and leave the joint loose;

[0041] S2. Introduce the connected cutting wire 8 into the third guide wheel 3 and the fourth guide wheel 4 of the multi-wire cutting equipment; wherein, the third guide wheel 3 is located upstream of the inlet groove wheel 9, and the fourth guide wheel 4 is located downstream of the outlet groove wheel 11.

[0042] S3. Introduce the connector of the cutting wire 8 into the infeed groove wheel 9, and bond the connector of the cutting wire 8 with tape.

[0043] S4. The cutting wire 8 is sequentially introduced into the multi-wire cutting equipment between the wire feeding wheel 7 and the third guide wheel 3. The cutting wire 8 is tensioned on the wire feeding side. After tensioning is completed, the cutting wire 8 is fed. When the joint of the cutting wire 8 walks out of the wire exit groove wheel 11, the tape is removed.

[0044] S5. When the joint of the cutting wire 8 reaches the take-up side reel 12, the joint of the cutting wire 8 is glued together with tape. Then, the cutting wire 8 is sequentially introduced into the multi-wire cutting equipment between the fourth guide wheel 4 and the take-up side reel 12, and the cutting wire 8 is stretched on the take-up side.

[0045] It should be noted that, as Figure 2 As shown, the multi-wire cutting equipment includes components such as a first guide roller 1, a second guide roller 2, a third guide roller 3, a fourth guide roller 4, a fifth guide roller 5, a sixth guide roller 6, a wire feeding side roller 7, a cutting wire 8, an infeed groove roller 9, a silicon carbide crystal rod 10, an outfeed groove roller 11, and a wire take-up side roller 12. The upstream and downstream relationships of these components can be referenced... Figure 2 As shown;

[0046] In step S1, the thread of the inlet slot wheel 9 is not completely tensioned when it is knotted with the thread of the wire release side wire wheel 7, and a small amount of slack is reserved. That is, the joint formed by the connection of the thread of the inlet slot wheel 9 and the thread of the wire release side wire wheel 7 is kept in a relaxed state, that is, the thread of the inlet slot wheel 9 and the thread of the wire release side wire wheel 7 are loosely connected, reducing the breakage caused by tension;

[0047] In step S2, a certain length of redundant wire is released, and the connected cutting wire 8 is introduced (wound) into the third guide wheel 3 and the fourth guide wheel 4, which are non-swinging arm guide wheels, to avoid the inertial force caused by the swinging of the arm from causing the wire to break; of course, the third guide wheel 3 and the fourth guide wheel 4 also serve to transmit and guide the wire; that is, this step optimizes the introduction path of the cutting wire 8, and the connected cutting wire 8 is directly introduced into the non-swinging arm guide wheel to avoid the inertial force fluctuation caused by the swinging of the guide wheel arm from causing the wire to break;

[0048] In step S3, the joint of the cutting wire 8 is bonded by a thin adhesive tape, so that after bonding, the adhesive tape is easily pressed into the groove 9.1 of the inlet slot wheel 9, that is, the wire joint is easily pressed into the groove 9.1 of the inlet slot wheel 9, which can prevent the joint from jumping and merging when the wire is running in the wire net, ensure the cutting reference, and reduce the failure rate of the wire running; wherein the thin adhesive tape is located between the wire joint and the groove 9.1; of course, the slot pitch of the inlet slot wheel 9 is small;

[0049] In step S4, the cutting wire 8 is sequentially introduced (wound) into the remaining guide wheels on the wire release side of the multi-wire cutting equipment, and the cutting wire 8 is tensioned on the wire release side. After tensioning is completed, the cutting wire 8 is run, and the adhesive tape is removed when the joint of the cutting wire 8 runs out of the outlet slot wheel 11;

[0050] In step S5, when the joint of the cutting wire 8 reaches the wire collection side wire wheel 12, the joint of the cutting wire 8 is bonded by an adhesive tape, and then the cutting wire 8 is sequentially introduced into the remaining guide wheels on the wire collection side of the multi-wire cutting equipment, and the cutting wire 8 is tensioned on the wire collection side; wherein, when the joint (thread) of the cutting wire 8 reaches the wire collection side wire wheel 12, it is bonded by an adhesive tape, one is because the joint is just at the wire wheel, and the subsequent tension needs to be applied to prevent the joint from opening, and the other is to prevent the joint from being loose and tangled, affecting the flatness of the wire wheel; that is, the cutting wire 8 is tensioned step by step on the wire release side and the wire collection side of the multi-wire cutting equipment, that is, the cutting wire 8 on the wire release side is tensioned first, and then the cutting wire 8 on the wire collection side is tensioned; wherein, the distributed tensioning is to tension the right side wire release side first, and the tension is small; unilateral tensioning can greatly reduce the probability of thread opening during wire running by applying tension on one side under the condition that the cutting wire can run; after the thread reaches the left side wire release side wire wheel, the cutting wire is sequentially introduced into each guide wheel, and tension is also applied to the left side wire collection side. Since the thread is already in the left side wire wheel, the wire net will not open and break under the condition that there is tension on both sides.

[0051] That is, the scheme can greatly reduce the probability of line breakage and improve the reliability of the joint by optimizing the guide wheel path (guide wheel obstacle avoidance) when the joint is relaxed and the wire is routed, and the joint time can also help to shorten the joint time, that is, to ensure the joint efficiency; of course, the scheme can be applied to the joint of the cutting wire with a wire diameter of 50-100 μm, that is, the scheme provides a method for jointing the broken steel cutting wire with a wire diameter of 50-100 μm.

[0052] In addition, it also needs to be explained that the scheme provides a method for efficiently and stably jointing the steel cutting wire with a wire diameter of 50-100 μm in the multi-wire cutting equipment, and the steps S1 to S5 above are the detailed steps of the jointing wire head step in the method, and before the jointing wire head step, it can also include:

[0053] (1) Record the cutting information: when the machine detects the broken wire and stops, record the current cutting position depth, cutting reciprocating direction and remaining wire length in the current cutting cycle;

[0054] (2) Clean the cutting cabin mortar: after the information is recorded and confirmed, use gauze to wipe off the mortar on the surface of the groove wheel, the residual wire mesh and the silicon carbide crystal;

[0055] (3) Raise the crystal: after the mortar cleaning is completed, in order to avoid further breakage and disorder of the wire mesh, press the remaining wire mesh on both sides of the silicon carbide crystal, operate on the control panel to raise the silicon carbide crystal to the loading and unloading position;

[0056] (4) Clean the wire mesh and wind the broken wire: after the silicon carbide crystal is raised to the loading and unloading position, the wire head is temporarily fixed with adhesive tape, the scattered wire mesh is cut off with scissors, and the broken wire wound on the groove wheel is cleaned out by reversing the wire on the control panel. If there is also a broken wire wound on the guide wheel, the broken wire can be manually wound out.

[0057] In the scheme, in the step S1, the wire head of the wire inlet groove wheel 9 of the multi-wire cutting equipment is jointed with the wire head of the wire releasing side wire wheel 7 and the joint is relaxed.

[0058] The wire head of the wire inlet groove wheel 9 of the multi-wire cutting equipment is knotted with the wire head of the wire releasing side wire wheel 7 and the joint is relaxed by 5-10 mm. When the wire head of the wire inlet groove wheel 9 is knotted with the wire head of the wire releasing side wire wheel 7, it is not completely tightened, and the joint is relaxed by 5-10 mm (a small amount of relaxation), that is, the two wire heads of the cutting wire 8 are jointed with a small amount of joint relaxation (5-10 mm), which facilitates the reduction of breakage caused by tensile stress.

[0059] Specifically, in the step S2, the jointed cutting wire 8 is introduced into the third guide wheel 3 of the multi-wire cutting equipment.

[0060] The spliced cutting line 8 is put out for 10 m of redundant line length, and then the cutting line 8 is introduced into the third wire guide wheel 3 of the multi-wire cutting equipment. Among them, the spliced cutting line 8 is put out for 10 m of redundant line length, so that the cutting line 8 can be directly introduced into the third wire guide wheel 3 and the fourth wire guide wheel 4, respectively. Of course, the cutting line 8 is preferentially introduced into the third wire guide wheel 3 and the fourth wire guide wheel 4, which can avoid the inertial force caused by the tilting of the swing arm from causing the cutting line to collapse.

[0061] Further, after the step S2, further comprising:

[0062] The cutting line 8 of the third wire guide wheel 3 is manually fixed and tensioned. Among them, the manual fixing of the cutting line 8 of the third wire guide wheel 3 is to prevent the cutting line from detaching from the wire guide wheel during tensioning. Because the line has tension and is in a relaxed state before tensioning, after tensioning is completed, the line naturally enters the groove of the wire guide wheel 9.

[0063] Further, in the step S3, introducing the joint of the cutting line 8 into the wire guide wheel 9 includes:

[0064] The joint of the cutting line 8 is manually introduced into the groove 9.1 of the wire guide wheel 9, so as to avoid the impact of tension fluctuation.

[0065] In the present scheme, in the step S3, the joint of the cutting line 8 is adhered by the adhesive tape, which includes:

[0066] The joint of the cutting line 8 is adhered by the adhesive tape.

[0067] It should be noted that the existing cloth-based adhesive tape is very thick, and in the case of small groove distance of the groove wheel, the line joint is difficult to enter the groove or the depth of the groove is shallow, and the wire process will cause the line joint to run to other grooves, and the situation of line jumping and parallel line occurs. Among them, the decorative paper adhesive tape is thinner than the cloth-based adhesive tape, and after being adhered, the decorative paper adhesive tape is easy to be pressed into the groove when the line is walked, that is, the line joint is easy to be pressed into the groove, which can prevent line jumping and parallel line. That is, the decorative paper adhesive tape can ensure that the line joint enters the groove because of its thinness, and will not be misaligned during the wire process, reducing the probability of line jumping and parallel line. Of course, the decorative paper adhesive tape adhered to the line joint can also ensure the strength of the line joint when tension is applied during the wire process. Of course, during the wire process, the decorative paper adhesive tape and the line joint will move together.

[0068] Specifically, the thickness of the decorative paper adhesive tape is ≤0.05 mm. That is, the decorative paper adhesive tape with a thickness of ≤0.05 mm is used to adhere the joint of the cutting line 8, and the line joint is more easily pressed into the groove, which can better prevent line jumping and parallel line.

[0069] Further, in the step S4, the cutting line 8 is introduced into the wire guide wheel between the wire guide wheel 7 on the pay-off side and the third wire guide wheel 3 of the multi-wire cutting equipment in sequence.

[0070] The cutting line 8 is introduced into the first wire guide wheel 1 and the second wire guide wheel 2 of the multi-wire cutting equipment in sequence; wherein, as shown in the figure, the wire release side wire wheel 7 is located upstream of the first wire guide wheel 1, the first wire guide wheel 1 is located upstream of the second wire guide wheel 2, and the second wire guide wheel 2 is located upstream of the third wire guide wheel 3. Figure 2

[0071] Further, in the step S5, introducing the cutting line 8 into the wire guide wheels of the multi-wire cutting equipment between the fourth wire guide wheel 4 and the wire winding side wheel 12 in sequence comprises:

[0072] The cutting line 8 is introduced into the fifth wire guide wheel 5 and the sixth wire guide wheel 6 of the multi-wire cutting equipment in sequence; wherein, as shown in the figure, the fourth wire guide wheel 4 is located upstream of the fifth wire guide wheel 5, the fifth wire guide wheel 5 is located upstream of the sixth wire guide wheel 6, and the sixth wire guide wheel 6 is located upstream of the wire winding side wheel 12. Figure 2

[0073] Meanwhile, before the step S1, further comprising:

[0074] S0, after the wire breakage, clean the wire net in the cutting cabin and restore the wire net to the original width.

[0075] It should be noted that after the wire breakage, the wire net in the cutting cabin will be missing a part of the wire, which will be either drawn out by the left and right wire rooms or wound on the groove wheel. At this time, it is necessary to clean up the messy wire and complete the wire net. If the wire net near the right wire room is missing, the wire from the right wire room will be released to supplement it. Conversely, the wire from the left wire room will be released to supplement it. The number of wires on the groove wheel during cutting (measured by a ruler) will be supplemented (supplemented to the original width), ensuring that the cutting piece seam and the wire are one-to-one corresponding.

[0076] Embodiment 1:

[0077] The method for connecting the broken steel cutting wire of the multi-wire cutting equipment provided by the scheme comprises the following steps:

[0078] ①After the wire breakage, clean the wire net in the cutting cabin and restore the wire net to the original width.

[0079] ②When knotting the wire head at the wire inlet groove wheel and the wire head of the wire release side wheel, 8mm slack is reserved, and 10m redundant wire length is released.

[0080] ③The connected cutting wire is introduced into the third wire guide wheel and the fourth wire guide wheel respectively, and then the wire joint is introduced into the groove of the wire inlet groove wheel step by step after manual fixation.

[0081] ④0.03mm masking tape is used to bond the wire joint, and after bonding, the right side is first stretched to 2N.

[0082] ​​⑤ Once the connection point reaches the recovery wheel (the cable take-up side), hook in the 5-6# guide wheels in sequence, then stretch the left side to 2N to complete the connection;

[0083] The right side is the pay-off side, and the left side is the take-up side. The step-by-step tensioning involves first tensioning the right pay-off side, and then tensioning the left side once the end of the thread reaches the take-up side.

[0084] In other words, this solution provides an efficient and stable method for connecting 50-100μm diameter steel cutting wires. After the connection is completed, it can avoid wire breakage during the tensioning process and significantly reduce the probability of wire jumps and merging, thus solving the defects of existing connection technologies.

[0085] This solution solves the industry problem of splicing fine steel wires (50-100μm) in silicon carbide cutting through a triple innovation of relaxed splicing, guide wheel obstacle avoidance, and thin adhesive tape, which can improve production efficiency and wafer yield.

[0086] Of course, the beneficial effects of this plan are:

[0087] ① Connection time reduced by 70-75%: from the traditional 120-180 minutes to 30-50 minutes; Specifically, if the wire is sequentially hung on the guide wheel from the right end and tension is applied during the wiring process, the wire end is extremely prone to breaking due to the tension (because the wire diameter is small, its tensile strength is very low); even if the wire end reaches the middle of the network, it is prone to breaking again under the combined tension from both sides; similarly, when the wire end reaches the left side, it is prone to breaking at the wire end due to tension; based on existing wiring statistics, the improvement, i.e., the time reduction, is as described above.

[0088] ② Improved connector reliability: By relaxing the connection and optimizing the guide wheel path during cable routing, the probability of cable breakage is significantly reduced;

[0089] ③Ensuring the integrity of the wiring network: The thin tape and step-by-step wiring design can avoid the situation of skipped or parallel wiring, while the cutting reference before the wire breaks is preserved.

[0090] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0091] The foregoing description of the disclosed embodiments enables a person skilled in the art to make or use the application. Modifications of these embodiments will occur to persons of skill in the art, and that the appended claims are intended to cover all such modifications that do not depart from the true spirit and scope of the application. Therefore, the application is not limited to the embodiments shown but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
