Description

Technical Field

[0001] This invention relates to an ultra-thin aluminum cutting device for electronic products, and more particularly to an ultra-thin aluminum cutting device for electronic products applied in the field of aluminum cutting equipment. Background Technology

[0002] Wire EDM machines are high-precision, high-efficiency processing equipment that utilizes the principle of electric spark discharge to process metal materials. Wire EDM machines offer the following advantages for cutting ultra-thin aluminum materials:

[0003] High-precision cutting: Wire EDM machines use the principle of electric spark discharge for cutting, enabling high-precision cutting and processing on ultra-thin aluminum materials. Because the cutting wire diameter is extremely fine, typically 0.1mm to 0.3mm, higher cutting accuracy and smaller cutting errors can be achieved.

[0004] Deformation-free cutting: Traditional mechanical cutting methods may cause deformation or damage to ultra-thin materials, while EDM wire cutting can avoid these problems. Since electrical discharge is a non-contact cutting method, it does not exert any pressure or deformation on the material, thus ensuring the integrity of the cut ultra-thin aluminum material.

[0005] High cutability: Ultra-thin aluminum materials are generally soft and easily deformed, but when cut by wire EDM, they are not limited by the hardness and toughness of the material and can be applied to the cutting of various types of ultra-thin aluminum materials.

[0006] High production efficiency: Wire EDM machines are characterized by high automation and easy operation, and can achieve continuous cutting, which can greatly improve production efficiency and work efficiency.

[0007] However, current wire EDM machines, because the processing of wire EDM requires the discharge between the cutting wire and the workpiece, are prone to wire wear, which requires frequent replacement or repair. Summary of the Invention

[0008] The technical problem that this invention aims to solve in light of the prior art is that existing cutting wires are prone to wear and require frequent replacement or repair.

[0009] To address the aforementioned problems, this invention provides an ultra-thin aluminum material cutting device for electronic products, comprising a cutting machine body, a protective box mounted on the cutting machine body, an electrical discharge cutting mechanism housed within the protective box, the electrical discharge cutting mechanism comprising an upper guide part and a lower wire guide device, the lower end of the lower wire guide device being connected to a lower housing, a rear guide housing being connected to the lower housing, a cutting wire being connected between the upper guide part and the lower wire guide device, and a traction mechanism matching the cutting wire being mounted on the upper end of the cutting machine body;

[0010] The lower wire guide device is equipped with a self-testing device that matches the cutting wire. The self-testing device includes an outer protective shell, inside which a guide tube is installed. The input end of the guide tube is connected to the output end of the lower wire guide device. A pair of X-ray sensors are installed inside the guide tube. A guide wheel is installed inside the lower housing. The input end of the guide wheel is connected to the output end of the self-testing device, and the output end of the guide wheel is connected to the input end of the rear guide housing.

[0011] The aforementioned aluminum cutting equipment enables the use of integral metal wires for cutting ultra-thin aluminum materials, thereby reducing wire wear, and allowing for rapid detection of the wires after cutting.

[0012] As a further improvement of this application, the length of the segmented cutting wire between the upper guide part and the lower wire guide device is less than the length of the segmented cutting wire inside the lower housing, which makes it easier to ensure that the cutting wire segment used for cutting can completely enter the lower housing for cooling each time.

[0013] As a further improvement of this application, an aluminum clamp is installed inside the protective box, and a clamping drive device matching the aluminum clamp is installed inside the protective box. The clamping drive device drives the aluminum clamp to clamp and move.

[0014] As a further improvement of this application, the output end of the upper guide is equipped with an upper wire guide device that matches the lower wire guide device, and a wire binding device that matches the cutting wire is installed inside the upper guide. The wire binding device limits the cutting wire, so that the cutting wire can be guided to the upper wire guide device.

[0015] As another improvement of this application, the cutting wire includes multiple metal wire segments connected by heat insulation rings, and the length of each metal wire segment is less than the length of the guide tube.

[0016] As a further improvement to this application, a winding device matching the cutting wire is installed inside the main body of the cutting machine tool. One end of the cutting wire is connected to the traction mechanism, and the other end of the cutting wire is connected to the winding device. The cutting wire is tightened, pulled, and adjusted by the cooperation of the traction mechanism and the winding device.

[0017] As another improvement of this application, the lower housing is filled with coolant, and an annular cavity is provided at the front end of the rear guide housing. An inlet pipe and an outlet pipe are connected between the annular cavity and the lower wire guide device. A circulating liquid pump that matches the inlet pipe and the outlet pipe is installed in the annular cavity, which can cool the cutting wire through the lower housing.

[0018] As another improvement of this application, a cutting control system is also included. The cutting control system includes a controller installed in the body of the cutting machine tool. A processor is connected to the controller. A winding device, a circulating liquid pump, an electrical discharge cutting mechanism, a guide wheel, a traction mechanism, and a clamping drive device are all connected to the controller. A data processing module, a clock module, a cutting control module, a self-test module, and an alarm module are connected to the processor. The self-test device is connected to the self-test module.

[0019] As a further improvement to this application, the cutting control module is used to control the cutting operation. The cutting control module adjusts the traction rate and traction time of the guide wheel and traction mechanism on the cutting wire according to the cutting path data.

[0020] In summary, this solution enables the traction and adjustment of the metal wire according to the cutting path during ultra-thin aluminum cutting, thereby achieving cutting using a whole metal wire, reducing metal wire wear, and allowing for rapid detection of the metal wire after cutting.

[0032] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0033] First implementation method: Figure 1-8 The present invention discloses an ultra-thin aluminum material cutting equipment for electronic products, including a cutting machine tool body 1, a protective box 2 installed on the cutting machine tool body 1, an aluminum material clamp installed inside the protective box 2, and a clamping drive device matching the aluminum material clamp installed inside the protective box 2, which drives the aluminum material clamp to clamp and move.

[0034] The protective box 2 houses an electrical discharge cutting mechanism 3, which includes an upper guide part 301 and a lower wire guide device 302. The lower end of the lower wire guide device 302 is connected to a lower housing 303, and a rear guide housing 304 is connected to the lower housing 303. A cutting wire 4 is connected between the upper guide part 301 and the lower wire guide device 302. The cutting wire 4 comprises multiple metal wire segments connected by heat insulation rings. Each metal wire segment is shorter than the length of the guide tube 502. A traction mechanism 7 matching the cutting wire 4 is installed at the upper end of the cutting machine body 1. The traction mechanism 7 is existing technology, consisting of multiple guide wheels and a traction end. It is installed by those skilled in the art using existing traction mechanisms for pulling the cutting wire 4.

[0035] The length of the segmented cutting wire 4 between the upper guide part 301 and the lower wire guide device 302 is less than the length of the segmented cutting wire 4 inside the lower housing 303, which makes it easy to ensure that the segmented cutting wire 4 used for cutting can completely enter the lower housing 303 for cooling each time.

[0036] The lower housing 303 is filled with coolant, and the front end of the rear guide housing 304 is provided with an annular cavity. An inlet pipe and an outlet pipe are connected between the annular cavity and the lower wire guide device 302. A circulating liquid pump that matches the inlet pipe and the outlet pipe is installed in the annular cavity, which can cool the cutting wire 4 through the lower housing 303.

[0037] The output end of the upper guide part 301 is equipped with an upper wire guide device that matches the lower wire guide device 302. The upper guide part 301 is equipped with a wire binding device that matches the cutting wire 4. The wire binding device limits the cutting wire 4, so that the cutting wire 4 can be guided to the upper wire guide device.

[0038] The main body 1 of the cutting machine tool is equipped with a winding device that matches the cutting wire 4. One end of the cutting wire 4 is connected to the traction mechanism 7, and the other end of the cutting wire 4 is connected to the winding device. The traction mechanism 7 and the winding device work together to tighten, pull and adjust the cutting wire 4.

[0039] This embodiment enables the traction and adjustment of the metal wire according to the cutting path during ultra-thin aluminum cutting, thereby achieving cutting using a whole metal wire and reducing metal wire wear.

[0040] Second implementation method:

[0041] Figure 5-7 As shown, a self-testing device 5 matching the cutting wire 4 is installed on the lower wire guide device 302. The self-testing device 5 includes an outer protective shell 501, and a guide tube 502 is installed inside the outer protective shell 501. The input end of the guide tube 502 is connected to the output end of the lower wire guide device 302. A pair of X-ray sensors 503 are installed inside the guide tube 502. A guide wheel 6 is installed inside the lower shell 303. The guide wheel 6 includes a pair of electric traction wheels. The cutting wire 4 passes between the pair of electric traction wheels. The input end of the guide wheel 6 is connected to the output end of the self-testing device 5. The output end of the guide wheel 6 is connected to the input end of the rear guide shell 304.

[0042] When this solution performs self-inspection, the cutting wire 4 entering the self-inspection device 5 is scanned by the X-ray sensor 503. By analyzing the collected signal data, the wear of the cutting wire 4 is determined. The non-destructive testing of materials by X-ray is an existing technology, and it can be installed by those skilled in the art using existing X-ray sensors 503 for non-destructive testing of materials.

[0043] The self-inspection of this solution can be carried out simultaneously during the cutting process. For example, during the intermittent adjustment of the cutting in the protective box 2, each section of the cutting wire 4 first enters the self-inspection device 5 when it is adjusted. The cutting wire 4 is self-inspected during the process of passing through the self-inspection device 5. Then the section of the cutting wire 4 can further enter the lower shell 303 for rapid cooling.

[0044] The third implementation method:

[0045] Figure 9 The diagram also includes a cutting control system, which includes a controller installed in the main body 1 of the cutting machine tool. The controller is connected to a processor. The winding device, circulating liquid pump, electric spark cutting mechanism 3, guide wheel 6, traction mechanism 7 and clamping drive device are all connected to the controller. The processor is connected to a data processing module, a clock module, a cutting control module, a self-test module and an alarm module. The self-test device 5 is connected to the self-test module.

[0046] The data processing module is used to read and write cutting path data;

[0047] The cutting control module is used to control the cutting operation. According to the cutting path data, the cutting control module adjusts the traction rate and traction time of the guide wheel 6 and the traction mechanism 7 on the cutting wire 4. The cutting control module can read and modify the cutting path data loaded into the system and work in conjunction with the controller.

[0048] Before the cutting operation, this solution loads the cutting path data and sets the speed at which the cutting wire 4 adjusts its vertical position during the cutting operation according to the flow of the cutting path.

[0049] Optionally, this application can intermittently adjust the cutting wire 4. During intermittent adjustment, the cutting wire 4 between the upper guide part 301 and the lower wire guide device 302 is divided into multiple segments. Then, multiple trigger nodes are set in the cutting path. When cutting to the trigger node, the cutting work is paused. Then, the cutting wire 4 is pulled and adjusted by the guide wheel 6 and the traction mechanism 7 to switch the cutting wire 4 to the next segment. This can reduce the local loss of the metal wire when performing long-path cutting work.

[0050] Optionally, when any segment of the cutting wire 4 enters the self-testing device 5 after adjustment, if the self-testing result of the segment of the cutting wire 4 meets the preset standard of those skilled in the art, the cutting control module can reset the segment of the cutting wire 4 to the cutting position during the next traction adjustment of the cutting wire 4.

[0051] If the preset standards are not met, intermittent adjustments will continue.

[0052] In summary, this solution enables the traction and adjustment of the metal wire according to the cutting path during ultra-thin aluminum cutting, thereby achieving cutting using a whole metal wire, reducing metal wire wear, and allowing for rapid detection of the metal wire after cutting.

[0053] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
