Description

Technical Field

[0001] This utility model relates to the technical field of circuit board cutting devices, specifically to a cutting device for circuit board production. Background Technology

[0002] In the production and processing of printed circuit boards (PCBs), cutting is a crucial step, as its precision and efficiency directly affect the quality of subsequent processing and the overall production schedule. With the rapid development of the electronics industry, PCBs are constantly evolving towards higher precision, miniaturization, and integration, placing more stringent demands on cutting processes.

[0003] Currently, traditional circuit board cutting devices face numerous problems in practical applications. In terms of positioning, most devices employ unidirectional clamping or simple support structures, making it difficult to achieve precise and stable fixation of the circuit board template. During cutting operations, the circuit board is prone to shifting or shaking due to stress, leading to deviations in cutting dimensions, severely impacting product quality, and even causing a large number of scraps, thus increasing production costs. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: A cutting device for circuit board production, see attached diagram. Figure 1 - Appendix Figure 4 The device includes two sets of side frames 1. A truss 2 is fixed to the top of each side frame 1. A crossbar is fixed between the side frames 1 on one side. A cylinder 14 and two sets of sliding rods 12 are fixed on the crossbar. A horizontal plate 11 is fitted on each set of sliding rods 12. A template positioning structure 4 is fixed on the left and right sides of the horizontal plate 11. A cutting device 3 is fitted at the middle of the top of each set of sliding rods 12. The cutting device 3 includes a pressing plate 31, a top cylinder 32 fixed to the middle of the pressing plate 31, and a connecting plate 34 fixed to the bottom of the pressing plate 31. The bottom of the pressing plate 31 is fixedly connected to a cutting blade 33. The middle of the connecting plate 34 is fixedly connected to a pressing rod 35. The template positioning structure 4 includes two vertical plates 41 on both sides, a pneumatic rod 42 fixed to the middle of the outer side of the vertical plate 41, and a fixing plate 44 fixed to the output end of the pneumatic rod 42. A locking plate 45 is fixed to the inner side of the fixing plate 44 on both sides. A base platform 5 is provided at the bottom of the locking plate 45.

[0024] The pressing plate 31 is fitted onto the sliding rods 12 at the four corners on both sides, and the inner walls of the vertical plate 41 at both ends are fixedly connected to the side plate 13. This structure ensures that when the top cylinder 32 drives the pressing plate 31 to move up and down, it always runs smoothly along a predetermined trajectory, preventing the cutting blade 33 from tilting or wobbling during the cutting process and ensuring the perpendicularity of the cut. More importantly, the top ends of the pressing rods 35 on both sides of the connecting plate 34 are fixed to the connecting plate 34 by threaded grooves and nuts. This detachable connection method allows for flexible adjustment of the height of the pressing rods 35 according to the thickness of the circuit board. Before the cutting action is started, the crimping rod 35 will contact and press the circuit board before the cutting blade 33. With the coordinated action of multiple crimping rods 35, the circuit board is firmly fixed on the base 5, which effectively prevents the circuit board from lifting or deforming due to the impact force of the cutting blade 33, making the cutting edge neater and smoother, and significantly improving the cutting quality of the circuit board.

[0025] The top of the connecting plate 34 is fixedly connected to the bottom of the pressing plate 31 via multiple sets of connecting cylinders 36, and the connecting plate 34 is located on both sides of the cutting blade 33. The top of the pressing rod 35 has a threaded groove structure, and multiple sets of holes are pre-drilled in the middle of the connecting plate 34. The top of the pressing rod 35 is fixed to the top of the connecting plate 34 with a nut. The top of the connecting plate 34 is fixed to the bottom of the pressing plate 31 via multiple sets of connecting cylinders 36. This multi-point connection method makes the connection between the two more robust and reliable, disperses the impact force generated during cutting, and extends the service life of the components. The detachable connection design between the pressing rod 35 and the connecting plate 34 allows operators to quickly replace the pressing rod 35 by removing the nut when it is worn or needs to be replaced to adapt to different specifications of circuit boards, without the need for large-scale disassembly of the entire device, greatly reducing maintenance difficulty and time costs. At the same time, the inner walls of both ends of the vertical plate 41 are fixedly connected to the side plate 13, further enhancing the overall rigidity of the template positioning structure 4, allowing the device to maintain stable performance even under long-term, high-frequency operation.

[0026] An auxiliary rod 43 is fixed to the outside of the fixed plate 44, and the auxiliary rod 43 passes through the vertical plate 41. A mating groove is opened inward in the middle of the clamping plate 45. A specified template can be clamped between the structures of the clamping plates 45. When the top cutting blade 33 cuts, it can be cut according to the template.

[0027] When the pneumatic rod 42 on the outer middle of the two vertical plates 41 drives the fixed plate 44 and the clamping plate 45 to move, the auxiliary rod 43 on the outer side passes through the vertical plate 41, providing stable guiding support for the movement of the fixed plate 44. This effectively avoids the shaking or deviation that may occur if the pneumatic rod 42 is driven alone, making the movement trajectory of the clamping plate 45 more precise. The mating groove opened inward in the middle of the clamping plate 45 can perfectly fit the edge of the circuit board template. Together with the stable support of the bottom of the circuit board by the base 5, a three-dimensional positioning system of "upper and lower clamping, left and right limiting" is formed. This design can not only quickly and firmly clamp the circuit board template, but also minimize the slight displacement of the template caused by force during the cutting process, ensuring the accuracy of the cutting position from the source. For products such as circuit boards that have extremely high precision requirements, this greatly reduces the scrap rate caused by inaccurate positioning.

[0028] The base platform 5 is fixed to the side frames 1 on both sides, and a slot 51 is provided through the center of the base platform 5. The slot 51 not only provides clearance for the cutting blade 33, preventing collision and damage, but also facilitates the removal of waste materials from the cutting process, reducing the impact of waste accumulation on production. The mating slot of the clamping plate 45 and the supporting structure of the base platform 5 work together to accommodate circuit board templates of different sizes and shapes, improving the versatility of the device. The lightweight design, such as the hollow structure of the pressing plate 31, reduces its own weight while maintaining structural strength, lowering the load on the top cylinder 32, saving energy consumption, and reducing the inertial force during device operation, making the overall operation more stable and efficient.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
