Description

Technical Field

[0001] This utility model relates to the field of electronic component manufacturing equipment technology, specifically to a cutting machine with a high-rigidity gantry frame. Background Technology

[0002] Electronic products are becoming increasingly diverse, powerful, and compact. This necessitates that key electronic components such as capacitors, resistors, inductors, and sensors be as small as possible while maintaining the highest possible reliability. Currently, surface-mount ceramic electronic components meet these requirements, exhibiting excellent performance in insulation, heat resistance, durability, and other aspects.

[0003] The manufacturing process of chip ceramic electronic components is as follows:

[0004] 1. Add electronic ceramic powder to binder and solvent, and disperse it into a flowable ceramic slurry;

[0005] 2. The ceramic slurry is cast and dried into ceramic films with a thickness of 5-30μm using a steel belt casting machine or a PET film casting machine.

[0006] 3. The bottom protective layer, composed of several ceramic films, is fixed to the carrier plate, i.e., stainless steel plate, by pressure. The inner electrode is printed, and then the second ceramic film is manually pressed on. The electrode is printed again until the required number of layers is reached. Finally, the top protective layer composed of several ceramic films is pressed on.

[0007] 4. After being laminated under high pressure hydrostatic pressure, it becomes a solid block, which is then cut with a cutting machine, and finally the electronic component blank is separated from the stainless steel plate.

[0008] 5. After the electronic component blanks are sintered at a high temperature of over 1000℃, they are polished, top electrodes are applied, and electroplating is performed to become finished products.

[0009] The cutting machine mentioned in step 4 above mainly operates as follows: the cutting blade moves up and down repeatedly, the platform advances gradually, the block is positioned on the platform, and the cutting blade cuts the block into microstructures. For example, the invention patent document with authorization announcement number CN105856437B discloses a high-speed intelligent cutting machine for chip electronic components, including a machine body structure, a platform, a detection and positioning mechanism, a cutting mechanism, and a control system; the cutting mechanism includes a blade holder mechanism and a cutting motor. The blade holder mechanism adopts an integrated structure consisting of a blade holder, a cutting blade, a guide column, a guide column bearing, a clamping block, a guard block, and a spring mechanism. The guard block is movable relative to the clamping block. During cutting, the guard block descends to press down on the block, then the cutting blade cuts down and rises, and finally the guard block rises. The platform and the support plate move forward a certain distance and stop. The guard block then descends again to press down on the block, the cutting blade cuts down and rises, and finally the guard block rises, entering the next cutting cycle.

[0010] like Figure 1 As shown, a traditional crossbeam 31 has a first support plate 11 and a second support plate 12 fixedly mounted on its left and right sides to form a gantry frame. The bottom ends of the first support plate 11 and the second support plate 12 are fixedly connected to the machine body structure 1, and the cutting mechanism 2 is fixedly mounted on the front side of the crossbeam 31. Because the cutting motor drives the cutting blade to move up and down repeatedly, a force is applied to the front side of the crossbeam. This results in low structural rigidity of the gantry frame, making the crossbeam prone to twisting and deformation, which in turn causes the cutting blade to be inaccurate in its cutting position on the block, leading to a decrease in product quality. Therefore, there is an urgent need in this technical field for a cutting machine with a high-rigidity gantry frame. Utility Model Content

Detailed Implementation

[0031] This utility model embodiment provides a cutting machine with a high-rigidity gantry frame. The overall technical concept is as follows:

[0032] Because the cutting mechanism applies dragging force to the front side of the crossbeam during operation, this invention chooses to set the first and second uprights on the rear side of the crossbeam. The front sides of both the first and second uprights are width-height dimensions, meaning they are surfaces composed of width and height. The left sides of both the first and second uprights are length-height dimensions, meaning they are surfaces composed of length and height. Regarding the specifications of item dimensions, the length of an item is greater than its width. Therefore, the first and second uprights connect to the rear side of the crossbeam using their own width-height dimensions, giving the gantry frame high rigidity. The structure of both the first and second uprights includes a U-shaped plate, a lower web plate, an L-shaped plate, and an upper web plate, referencing the structural characteristics of I-beams and applying them to the gantry frame of the cutting machine. The I-beam's cross-sectional shape is reasonable, and the web plate between the two flanges provides good torsional stiffness, while also possessing high bending and compressive strength; this further contributes to the high rigidity of the gantry frame of this invention.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] See Figures 1 to 6 The preferred embodiment of this utility model.
