Description

Technical Field

[0001] This utility model relates to the field of patch cutting technology, specifically a patch cutting device. Background Technology

[0002] The main purpose of surface mount technology (SMT) for electronic components is to achieve miniaturization, high integration, and improved production efficiency in electronic products. SMT technology is a process that involves directly mounting electronic components onto the surface of a printed circuit board (PCB). This method significantly reduces the size of electronic products, adapting to the modern trend towards lightweight and compact electronic devices. During SMT implementation, a slitting device is needed to cut the components into appropriate sizes.

[0003] Some surface mount slitting devices can only slit surface mounts of a fixed thickness or size, and cannot slit different thicknesses or sizes at the same time, which limits their use. Therefore, they do not meet the current needs. In response, we have proposed a surface mount slitting device. Utility Model Content

[0004] The purpose of this utility model is to provide a patch cutting device to solve the problem that the patch cutting device proposed in the background art can only cut patches of a fixed thickness or size, and cannot cut patches of different thicknesses or sizes at the same time, which leads to the limitation of its use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a patch cutting device, including a worktable, with support rods fixedly connected to both sides of the upper end of the worktable, a support plate fixedly connected between the top ends of the two support rods, a movable seat connected to the bottom end of the support plate by a cylinder, fixed plates fixedly connected to both sides of the bottom end of the movable seat, a roller connected to the two fixed plates by a motor, a plurality of cutting blades provided on the outer surface of the roller, and an annular seat slidably connected to the outer surface of the roller fixedly connected to both sides of the outer surface of each cutting blade.

[0006] Preferably, the outer surface of the roller is provided with grooves at both the front and back, and each annular seat is fixedly connected to a slider that is slidably connected inside the groove.

[0007] Preferably, the annular seat has movable grooves at both the top and bottom, and a limiting plate is slidably connected inside the movable groove. A spring is fixedly connected between the upper end of the limiting plate and the inner wall of the movable groove.

[0008] Preferably, a limiting block is fixedly connected to the side of the limiting plate away from the spring, and one end of the limiting block passes through the movable groove and extends to the outside of the annular seat. The outer surface of the limiting block is arc-shaped.

[0009] Preferably, a plurality of limiting holes are provided at equal intervals on the upper and lower surfaces of the outer surface of the roller, one end of the limiting block is inserted into the corresponding limiting hole, and the arc surface of the limiting block slides in contact with the outer surface of the upper end of the limiting hole.

[0010] Preferably, both ends of the movable seat are slidably connected to the outer surface of the support rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model pushes the cutting blade so that the slider inside the annular seat on both sides of the cutting blade slides into the inside of the groove. The outer arc of the limiting block slides into contact with the outer surface of the upper end of the limiting hole, thereby pushing the limiting block to compress the spring and move and retract into the inside of the movable groove. Then, when the cutting blade moves to the appropriate position, the movable groove corresponds to the limiting hole. At this time, the spring releases its elastic force, thereby pushing the limiting block to insert into the inside of the limiting hole, thereby adjusting and fixing the position of the cutting blade. It is also convenient to adjust the distance between each cutting blade according to the thickness or size of the patch to be cut.

[0013] 2. In this utility model, after adjusting the cutting blade, the patch is placed above the worktable and below the cutting blade. Then, the cylinder is activated to drive the movable seat with the cutting blade to move downward. The two ends of the movable seat are slidably connected to the outer surface of the support rod, so that the movable seat drives the cutting blade to move downward smoothly and cut the patch.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 3 An embodiment of this utility model provides a patch cutting device, including a workbench 1. Support rods 2 are fixedly connected to both sides of the upper end of the workbench 1. A support plate 3 is fixedly connected between the top ends of the two support rods 2. A movable seat 5 is driven to the bottom end of the support plate 3 by a cylinder 4. Fixed plates 6 are fixedly connected to both sides of the bottom end of the movable seat 5. A roller 8 is driven to the two fixed plates 6 by a motor 7. A plurality of cutting blades 9 are provided on the outer surface of the roller 8. An annular seat 10 that is slidably connected to the outer surface of the roller 8 is fixedly connected to both sides of the outer surface of each cutting blade 9.

[0020] The roller 8 has grooves 801 on both the front and back of its outer surface. Each annular seat 10 has a slider 11 that is fixedly connected to the inside of the groove 801. By pushing the cutting blade 9, the sliders 11 inside the annular seats 10 on both sides of the cutting blade 9 are slidably connected to the inside of the groove 801.

[0021] The annular seat 10 has movable grooves 1001 on both the upper and lower sides. A limiting plate 12 is slidably connected inside the movable groove 1001. A spring 13 is fixedly connected between the upper end of the limiting plate 12 and the inner wall of the movable groove 1001. A limiting block 14 is fixedly connected to the side of the limiting plate 12 away from the spring 13. One end of the limiting block 14 passes through the movable groove 1001 and extends to the outside of the annular seat 10. The outer surface of the limiting block 14 is arc-shaped. Several limiting holes 802 are equally spaced on the upper and lower sides of the outer surface of the roller 8. One end of the limiting block 14 is inserted into the corresponding limiting hole 802, and the arc surface of the limiting block 14 slides in contact with the outer surface of the upper end of the limiting hole 802.

[0022] The arc on the outer surface of the limiting block 14 slides into contact with the outer surface of the upper end of the limiting hole 802, thereby pushing the limiting block 14 to compress the spring 13 and move and retract into the interior of the movable groove 1001. Then, when the cutting blade 9 moves to the appropriate position, the movable groove 1001 corresponds to the limiting hole 802. At this time, the spring 13 releases its elastic force, thereby pushing the limiting block 14 to insert into the interior of the limiting hole 802, thereby adjusting and fixing the position of the cutting blade 9, and making it convenient to adjust the distance between each cutting blade 9 according to the thickness or size of the patch to be cut.

[0023] After the cutting blade 9 is adjusted, the patch is placed above the worktable 1 and below the cutting blade 9. Then, the cylinder 4 is activated to drive the movable seat 5, which is equipped with the cutting blade 9, to move downward. Since both ends of the movable seat 5 are slidably connected to the outer surface of the support rod 2, the movable seat 5 drives the cutting blade 9 to move downward smoothly and cut the patch.

[0024] When the patch slitting device is in use, by pushing the cutting blade 9, the sliders 11 inside the annular seats 10 on both sides of the cutting blade 9 are slidably connected to the inside of the groove 801. The arc of the outer surface of the limiting block 14 slides into contact with the outer surface of the upper end of the limiting hole 802, thereby pushing the limiting block 14 to compress the spring 13 and move and retract into the inside of the movable groove 1001. Then, when the cutting blade 9 moves to the appropriate position, the movable groove 1001 corresponds to the limiting hole 802. At this time, the spring 13 releases its elastic force, thereby pushing the limiting block 14 to insert into the inside of the limiting hole 802, thereby adjusting and fixing the position of the cutting blade 9, and making it convenient to adjust the distance between each cutting blade 9 according to the thickness or size of the patch to be slit.

[0025] After the cutting blade 9 is adjusted, the patch is placed above the worktable 1 and below the cutting blade 9. Then, the cylinder 4 is activated to drive the movable seat 5, which has the cutting blade 9, to move downward. The two ends of the movable seat 5 are slidably connected to the outer surface of the support rod 2, so that the movable seat 5 drives the cutting blade 9 to move downward smoothly and cut the patch.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
