Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic engineering, and particularly relates to a device for preventing edge chipping during cutting of a circuit board substrate. Background Art
[0002] During the processing of a circuit board substrate, cutting is a key link. However, traditional circuit board substrate cutting devices have many deficiencies.
[0003] During the cutting process, the height and angle of the cutting blade of traditional devices are usually fixed and difficult to adjust according to different substrate characteristics and cutting requirements. This results in easy occurrence of edge chipping during cutting, affecting the quality of the circuit board substrate and subsequent use. At the same time, for the fixing method of the substrate, traditional devices mostly adopt rigid fixing, which is likely to cause damage to the substrate during the fixing process, especially for some substrates with brittle texture or high surface requirements. This not only increases the scrap rate but also raises the production cost. Content of the Utility Model

[0008] Preferably, one side of the connecting plate away from the lead screw is fixedly connected to the outer wall of the slider. A limiting post is fixedly connected to the bottom of the connecting plate. The outer wall of the limiting post is slidably connected to the inner wall of the fixed cylinder.

[0022] The outer wall of the inserting plate 44 is slidably connected to the inner wall of the slider 41, the outer wall of the inserting post 42 is slidably connected to the inner wall of the fixed seat 1, the inner wall of the fixed seat 1 is slidably connected to the outer wall of the slider 41, the fixing component 3 includes a connecting plate 31, a lead screw 33 is rotatably connected to the inner wall of the connecting plate 31, a fixing cylinder 32 is threadedly connected to the outer wall of the lead screw 33, a thread groove is provided in the wall of the fixing cylinder 32 and meshes with the lead screw 33, the bottom of the fixing cylinder 32 is fixedly connected to a fixing frame 35, and the bottom of the fixing frame 35 is fixedly connected to a flexible disk 36.
[0023] One side of the connecting plate 31 away from the lead screw 33 is fixedly connected to the outer wall of the slider 41. A limiting column 34 is fixedly connected to the bottom of the connecting plate 31. The outer wall of the limiting column 34 is slidably connected to the inner wall of the fixed cylinder 32. A plug block 37 is slidably connected to the inner wall of the top of the fixed frame 35. The inside of the fixed frame 35 is blocked by the plug block 37. A communication groove 38 is formed in the wall of the fixed frame 35.
[0024] Working principle:
[0025] During use, first place the circuit board substrate on the suction cup group 2, and press the substrate to fix it on the suction cup group 2. Then use the fixing component 3 to move downward, so as to clamp the substrate up and down through the fixing component 3 and the suction cup group 2, thereby fixing the position of the substrate. Then the position of the cutting blade 48 in the cutting component 4 can be adjusted. After the position of the cutting blade 48 is adjusted, the stepping motor 47 can be started. Subsequently, move the cutting component 4 along the fixed seat 1, thereby cutting the substrate into a circular substrate.
[0026] When using the fixing component 3, just grasp the handle on the lead screw 33 and drive the lead screw 33 to rotate in the fixed cylinder 32 through the handle. Since the lead screw 33 is threadedly connected to the fixed cylinder 32, when the lead screw 33 rotates in the connecting plate 31, the fixed cylinder 32 slides up and down, and the limiting column 34 beside the fixed cylinder 32 is used to limit the position of the fixed cylinder 32, thereby preventing the fixed cylinder 32 from rotating.
[0027] After the floppy disk 36 on the fixed frame 35 touches the substrate, the plug block 37 on the fixed frame 35 can be slid out, so that the floppy disk 36 fits on the substrate, and the air in the floppy disk 36 is squeezed out from the plug block 37 through the communication groove 38. After the air in the floppy disk 36 is completely exhausted, the plug block 37 can be slid back into the fixed frame 35, so as to clamp the substrate up and down through the floppy disk 36 and the suction cup group 2.
[0028] When the position of the cutting blade 48 needs to be adjusted, just slide the positioning block 45 upward to unlock the turntable 46. Then the turntable 46 can be rotated to change the position of the cutting blade 48. After the position of the cutting blade 48 is adjusted, just release the force on the positioning block 45. A spring is provided on the positioning block 45. Therefore, under the pull of the spring, the positioning block 45 slides back into the positioning hole on the turntable 46 to re-lock the position of the turntable 46. And the insertion plate 44 can be slid out of the slider 41 to unlock the sliding block 43. Then just slide the position of the sliding block 43 up and down to change the height of the cutting blade 48. After the position of the sliding block 43 is adjusted, insert the insertion plate 44 through the slider 41 again and slide it into the sliding block 43 to re-lock the position of the sliding block 43.
[0029] After the position adjustment of the cutting disc 48 is completed, simply slide the plug post 42 out of the slider 41 to release the locking of the slider 41. Then, grasp the handles on both sides of the slider 41 to drive the slider 41 to move in a circular motion along the chute on the fixed base 1, enabling the substrate to be cut into a circular substrate.
