[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figures 1 to 9As shown, this utility model provides a feed assembly suitable for wire EDM equipment. The feed assembly includes: a lifting sliding member 142, which is movably and vertically arranged; a feed lifting drive member 143, the output end of which is drivenly connected to the lifting sliding member 142 to drive the lifting sliding member 142 to perform lifting and lowering movements; and a feed component 144, which is arranged above the lifting sliding member 142 to carry the material plate assembly 25 from the loading and unloading device 2 of the wire EDM equipment and drive the material plate assembly 25 to perform lifting and lowering movements with the lifting sliding member 142; at least a portion of the feed component 144 is movably arranged along at least one horizontal direction to adjust the position of the material plate assembly 25.

[0037] Thus, the feed assembly of this utility model, by setting a feed component that is at least partially movable along at least one horizontal direction, provides a larger material adjustment range, better visibility and operability, and quickly and accurately adjusts the position of the material automatically before feed, bringing revolutionary improvements to the operation of wire EDM equipment. It solves the problem that the feed assembly of wire EDM equipment in the prior art leads to poor cutting effect of wire EDM equipment, thereby significantly improving the production efficiency and material cutting accuracy of wire EDM equipment.

[0038] like Figures 4 to 6 As shown, the feed component 144 includes: an adjusting base 1441, which is mounted above the lifting sliding member 142 to move up and down with the lifting sliding member 142; a bearing adjusting member 1442, which is movably disposed on the adjusting base 1441 along a second direction and is used to support the material plate assembly 25; and an adjusting lifting member 1443, which is movably disposed on the bearing adjusting member 1442 and located between the bearing adjusting member 1442 and the material plate assembly 25 to drive the material plate assembly 25 to move up and down relative to the bearing adjusting member 1442, so that the material plate assembly 25 moves downward to contact and press against the bearing adjusting member 1442, or moves upward to release the material plate assembly 25, so that the material plate assembly 25 can smoothly enter and exit the cutting device 1. This type of equipment can adapt to materials of different sizes, improving its versatility and cutting efficiency. It is especially suitable for production lines that require frequent changes of materials to be cut, ensuring that each specification of material can be cut in the optimal position, thereby improving cutting efficiency and product quality and reducing production costs.

[0039] like Figure 5 and Figure 6As shown, the adjustment base 1441 includes: an adjustment support plate 14411, which is connected to and located above the lifting sliding member 142; an adjustment drive component 14412, the main body of which is disposed on the adjustment support plate 14411, and the output end of which is drivenly connected to the bearing adjustment member 1442 to drive the bearing adjustment member 1442 to move along a second direction; an adjustment guide component 14413, which is disposed on the adjustment support plate 14411 and connected to the bearing adjustment member 1442 to guide the movement of the bearing adjustment member 1442 along the second direction; and a first limiting component 14414, which is disposed on the adjustment support plate 14411 to limit the movement of the bearing adjustment member 1442 along the second direction. In this way, precise guidance and limiting can ensure the positional accuracy of the material during the cutting process, reduce material deviation during cutting, and make it suitable for cutting scenarios with extremely high requirements for material positional accuracy, thus ensuring cutting precision and improving product quality.

[0040] like Figure 5 and Figure 6 As shown, the load-bearing adjustment component 1442 includes: a load-bearing adjustment plate 14421, which is disposed above the adjustment base 1441; the output end of the adjustment drive component 14412 is drivenly connected to the load-bearing adjustment plate 14421; the load-bearing adjustment plate 14421 is slidably connected to the adjustment support plate 14411 via the adjustment guide component 14413; and an adjustment lifting component 1443 is slidably disposed above the load-bearing adjustment plate 14421. Two positioning components 14422 extend along a first direction and are spaced apart along a second direction on opposite sides of the load-bearing adjustment plate 14421 for contacting or separating from the material plate assembly 25. This design provides stable horizontal support, ensuring material stability, reducing material swaying during cutting, ensuring the material's position is fixed during cutting, reducing damage rate, and improving cutting accuracy.

[0041] like Figure 5 and Figure 6As shown, the bearing adjustment component 1442 includes: a horizontal guide component 14423, which is mounted above the bearing adjustment plate 14421 and extends along a first direction to guide the horizontal movement of the material plate assembly 25 along the first direction; and a horizontal limiting component 14424, which is mounted on the bearing adjustment plate 14421 and located at one end of the positioning component 14422 to limit the horizontal movement of the material plate assembly 25 along the first direction, thereby further improving the positional accuracy of the material during the cutting process. For the material plate assembly 25, it can ensure the positional accuracy of the material during the cutting process, improve the cutting quality, and reduce the defect rate.

[0042] like Figure 5 and Figure 6 As shown, the load-bearing adjustment component 1442 includes an adjustment lifting drive component 14425. The main body of the adjustment lifting drive component 14425 is disposed on the load-bearing adjustment plate 14421. The output end of the adjustment lifting drive component 14425 is drivenly connected to the adjustment lifting component 1443 to drive the adjustment lifting component 1443 to perform lifting and lowering movements.

[0043] like Figure 5 and Figure 6 As shown, the load-bearing adjustment component 1442 includes: a vertical guide assembly 14426, which is installed above the load-bearing adjustment plate 14421 and slidably connected to the adjustment lifting component 1443 to guide the lifting movement of the adjustment lifting component 1443; and a vertical limiting assembly 14427, which is installed above the load-bearing adjustment plate 14421 to limit the lifting movement of the adjustment lifting component 1443. This ensures the stability of the material in the vertical direction, reduces the vertical deviation of the material during the cutting process, guarantees the stability of the material cutting process, effectively reduces vibration, and improves cutting quality and efficiency.

[0044] like Figure 5 and Figure 6As shown, the adjusting lifting component 1443 includes: a lifting plate 14431, which is disposed above the bearing adjusting plate 14421 and between two positioning components 14422, and the output end of the adjusting lifting drive component 14425 is drivenly connected to the lifting plate 14431; a load-bearing component 14432, which is disposed on and above the lifting plate 14431 for contacting or separating from the material plate assembly 25; and a clamping component 14433, which is disposed on the lifting plate 14431 and is used to contact or separate from the material plate assembly 25. The bottom plate limiting groove 255 is inserted to limit the lifting movement of the material plate assembly 25 relative to the lifting plate 14431. After the clamping member 14433 clamps the material plate assembly 25, it can also limit the movement of the material plate assembly 25 in the first and second directions, thereby ensuring that the entire material plate assembly 25 will not move during cutting. The adjusting lifting member 1443 is used to make the material plate assembly 25 contact the two positioning members 14422 and separate it from the load-bearing member 14432, or to make the material plate assembly 25 separate from the two positioning members 14422 and contact the load-bearing member 14432. In this way, the material plate assembly 25 can be pressed against the two positioning members 14422 of the bearing adjusting plate 14421 during cutting, so as to ensure the stability of the material feeding process, achieve precise control of the material feeding process, and improve the cutting accuracy.

[0045] Specifically, the thickness of the clamping member 14433 is less than the height of the bottom plate limiting groove 255, and the upper surface of the load-bearing member 14432 is higher than the upper surface of the clamping member 14433.

[0046] like Figure 1 As shown, the feed assembly includes a flexible bellows assembly 145, which is sleeved on at least a portion of the feed member 144 to prevent cutting fluid from entering the interior of the feed member 144. The flexible bellows assembly 145 can move up and down during the feed and retraction operations.

[0047] like Figure 10 As shown, this utility model provides a cutting device, including a base 10 and a central assembly 11, a winding assembly 12, a cutting chamber assembly 13, and a feed assembly 14 spaced apart on the base 10; wherein, the feed assembly 14 is the aforementioned feed assembly; the feed assembly 14 is located below the cutting chamber assembly 13 of the wire cutting device 1; the various components work in coordination, improving the cutting efficiency and stability of the cutting device, while simplifying the operation process and reducing maintenance costs, making it suitable for large-scale industrial production. Its efficient and stable working performance and low maintenance costs can greatly improve production efficiency and economic benefits.

[0048] In this way, by placing the feed assembly below the cutting chamber assembly 13 and cooperating with the loading and unloading device 2 of the wire EDM equipment, the present invention achieves automatic loading and unloading of materials, which improves the automation and intelligence of the loading and unloading process of the wire EDM equipment, improves the feed stability and slicing quality of the feed assembly, improves the stability and accuracy of the material during the cutting process, reduces material shaking and positional deviation during the cutting process, thereby improving the cutting accuracy. It solves the problem that the feed assembly of the wire EDM equipment in the prior art is inconvenient for loading and unloading and daily maintenance because it is located above the main roller of the cutting chamber, and is also conducive to daily maintenance and inspection.

[0049] like Figure 10 As shown, the base 10 also includes a first base body 101 and a second base body 102 connected to each other; wherein, the winding assembly 12 is disposed in the first base body 101, and the central assembly 11 is installed above the first base body 101; in the second base body 102, the feed assembly 14 is disposed in the second base body 102, the lifting sliding member 142 is movably disposed on the base 10, the main body of the feed lifting drive member 143 is connected to the base 10, and the cutting chamber assembly 13 is installed above the second base body 102. This not only optimizes the space utilization of the equipment, but also makes the maintenance and adjustment of the cutting device more convenient, and improves the operating efficiency and safety of the cutting device.

[0050] like Figure 10 As shown, the first base 101 is provided with an intermediate cavity 1011 and two mounting cavities 1012, which are located on opposite sides of the intermediate cavity 1011. There are two winding assemblies 12, which are respectively arranged in the two mounting cavities 1012. Each winding assembly 12 includes a tension detection assembly, a wire laying assembly, and a wire take-up and unwinding assembly.

[0051] Specifically, the feed assembly 14 also includes a feed base 141 fixedly connected to the base 10, the feed base 141 being mounted on the base 10 of the cutting device 1 of the wire cutting equipment; a lifting sliding member 142, the lifting sliding member 142 being movably mounted on the feed base 141; and a feed lifting drive member 143, the main body of the feed lifting drive member 143 being connected to the base 10 through the feed base 141.

[0052] like Figure 1 As shown, the feed assembly 14 includes a sliding guide 146, and the lifting slide 142 is slidably connected to the feed base 141 through the sliding guide 146.

[0053] like Figure 10As shown, this utility model provides a wire cutting device, including: a cutting device 1, which is the cutting device described above; and a loading / unloading device 2, which is movably disposed on one side of the cutting device 1 to exchange materials with the feed assembly 14. This achieves automated loading and unloading of the wire cutting equipment, greatly improving production efficiency, reducing errors and labor intensity caused by manual operation, and is suitable for large-scale, continuous industrial production, such as the cutting of semiconductor wafers and solar panels, significantly improving the automation level and production efficiency of the production line.

[0054] The first direction and the second direction of this utility model are perpendicular to each other and both parallel to the support base surface of the cutting device 1 of the wire cutting equipment. The first direction is perpendicular to the rotation axis of the main roller in the cutting chamber assembly 13 of the cutting device 1, and the second direction is parallel to the rotation axis of the main roller in the cutting chamber assembly 13 of the cutting device 1.

[0055] Specifically, the wire cutting equipment is a slicing machine. By adopting the aforementioned feed assembly 14, it can achieve high-precision, high-efficiency, and high-safety cutting operations. It is suitable for precision cutting of hard and brittle materials in industries such as photovoltaics, semiconductors, and electronics, and has significant industrial application value.

[0056] The working process of the feed assembly of this utility model is as follows:

[0057] (1) Receiving material: Adjust the lifting component 1443 to move upward so that the upper surface of the load-bearing component 14432 in the adjusting lifting component 1443 of the feed component 144 is flush with the upper surface of the load-bearing component in the loading and unloading device for carrying the material plate assembly 25; the push-pull component in the loading and unloading device 2 pushes the material plate assembly 25 onto the feed component until the material plate assembly 25 contacts the horizontal limiting component 14424 (e.g., Figure 7 (As shown); Throughout the material receiving process, the load-bearing component 14432 remains in contact with the bottom of the material plate assembly 25 so that the material plate assembly 25 is in a high position and will not come into contact with the positioning component 14422 on the load-bearing adjustment component 1442 of the feed component 144.

[0058] (2) Unloading: The push-pull assembly of the loading and unloading device 2 is retracted.

Figure 9 (As shown).

[0060] (4) Tool setting: Based on the signal feedback from the distance detection component in the cutting chamber assembly 13, the adjustment base 1441 in the feed assembly 14 drives the bearing adjustment component 1442, the adjustment lifting component 1443 and the material plate assembly 25 located above them to move in the second direction to complete the tool setting operation of the material.

[0061] (5) Feeding: The feeding lifting drive 143 drives the lifting sliding component 142 to drive the feeding component 144 to continue to rise, so as to drive the material plate assembly 25 located on the feeding component 144 to rise, and complete the feeding of the material.

[0062] (6) Retraction: After cutting, the feed lifting drive 143 drives the lifting sliding component 142 to lower the feed component 144, thereby lowering the material plate assembly 25 located on the feed component 144 and completing the material retraction.

[0063] (7) Unloading: Adjust the lifting component 1443 to move upward so that the bottom of the material plate assembly 25 is separated from the two positioning components 14422 of the bearing adjustment component 1442 and contacts the load-bearing component 14432; adjust the lifting component 1443 to continue to move upward so that the material plate assembly 25 continues to rise until the upper surface of the load-bearing component 14432 in the adjusting lifting component 1443 of the feed component 144 is flush with the upper surface of the bearing component in the loading and unloading device for bearing the material plate assembly 25. The push-pull component of the loading and unloading device 2 drives the material plate assembly 25 to move onto the material support component of the loading and unloading device 2 to complete the unloading operation.

[0064] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0065] The feed assembly of this utility model is applicable to wire EDM equipment.

Thus, the feed assembly of this utility model, by setting a feed component that is at least partially movable along at least one horizontal direction, provides a larger material adjustment range, better visibility and operability, and quickly and accurately adjusts the position of the material automatically before feed, bringing revolutionary improvements to the operation of wire EDM equipment. It solves the problem that the feed assembly of wire EDM equipment in the prior art leads to poor cutting effect of wire EDM equipment, thereby significantly improving the production efficiency and material cutting accuracy of wire EDM equipment.
