Description

Technical Field

[0001] The present invention belongs to the field of material processing, and particularly relates to a brittle material substrate fracture device. Background Art

[0002] Brittle materials refer to materials that, under the action of external forces (such as tension, impact, etc.), only produce very small deformations before fracture and destruction. Contrary to toughness, only very small elastic deformations occur until fracture, without plastic deformation, that is, brittle materials have very poor resistance to dynamic loads or impacts.

[0003] At present, brittle materials are widely used in the field of electronic devices. During the manufacturing process of electronic devices, to meet the requirements of industrial design, various shaped workpieces need to be cut from substrates made of brittle materials. Among them, "cutting" directly affects the accuracy and quality of the workpieces, and there are defects at the positions where the substrate fractures after cutting, making it not only unsightly but also potentially injuring the operators. At the same time, during cutting, the operators may repeat the operation because they do not know whether the substrate has fractured, resulting in waste of labor. Therefore, the present invention proposes a brittle material substrate fracture device, which first pushes and presses it downward and then performs stretching, so as to ensure the completion of substrate fracture. Summary of the Invention

[0028] The following further describes in detail the implementation mode of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0029] As Figures 1-6 described, this embodiment provides a brittle material substrate fracture device, including a housing 1 and a substrate 9. A support platform 2 is arranged inside the housing 1. One end of the support platform 2 is fixedly connected to a fixed block 1. The bottom end of the fixed block 1 is fixedly connected to a fixed panel 4. The bottom end of the fixed panel 4 is fixedly connected to a cutting blade 5. Telescopic tubes 39 are fixedly arranged at both ends of the cutting blade 5 at the bottom end of the fixed panel 4. One end of the telescopic tube 39 away from the fixed panel 4 is fixedly connected to a pushing device 6.

[0030] The pushing device 6 is arranged at both ends of the cutting blade 5 to deepen the cracks on the substrate 9 more evenly by pushing after the cutting blade 5 cuts the substrate 9, so as to enhance the fracture effect of the substrate 9.

[0031] A base 7 is arranged in the inner cavity of the housing 1. One end of the base 7 is rotatably connected to a rotating disc 8. The top end of the rotating disc 8 is detachably connected to a substrate 9. Limiting blocks 10 are arranged at the four corners of the substrate 9. The bottom end of the limiting block 10 is fixedly connected to a support column 11, and the end of the support column 11 away from the rotating disc 8 is fixedly connected to the base 7. A panel 12 is arranged on one side of the rotating disc 8. An electric telescopic tube 15 is fixedly arranged at one end of the panel 12 close to the support column 11. A polishing and cleaning rod 14 is arranged around one end of the electric telescopic tube 15 away from the panel 12. A tensile device 13 is arranged on the side of the base 7 away from the panel 12.

[0032] The rotating disk 8 is provided because during cutting, different usage requirements impose demands on the shape of the cutting substrate 9. Therefore, by rotating the rotating disk 8, the angle can be adjusted to meet the requirements for cutting substrates 9 of various shapes. The reasonable combination of the electric telescopic tube 15 and the grinding and cleaning rod 14 achieves the effect of removing the barbs at the fracture of the substrate 9 and making it as smooth as possible. First, the length is adjusted by the telescopic movement of the electric telescopic tube 15, that is, the position of the grinding and cleaning rod 14 is adjusted. Then, the grinding and cleaning rod 14 is used to grind and clean the disconnected position of the substrate 9 to achieve a smooth effect at the disconnected position, avoiding the possibility of workers' hands being injured by the defects when picking up the substrate 9. At the same time, if the cutting part of the substrate 9 is not neat, it can also prevent damage to other materials or the operation of the device when used with other materials, thus affecting the implementation effect.

[0033] The pushing device 6 is internally provided with a second housing 16. There are three grooves in the second housing 16, which are groove one 17, groove two 18, and groove three 19 in sequence from the top to the bottom, and the three grooves are interconnected. An active block one 20 is arranged inside the groove one 17. One end of the active block one 20 is fixedly connected with a first spring 22, and the first spring 22 extends to the top end of the inner cavity of the groove one 17. A pushing column 23 is arranged inside the groove two 18. The pushing column 23 has an irregular shape, that is, it is narrower at the top and wider at the bottom. A groove four 21 is formed on the active block one 20, and the width of the groove four 21 is equal to the width of the end of the pushing column 23 close to the active block one 20. The active block one 20 is slidably connected with the pushing column 23. The pushing column 23 is penetrated by a second spring 24, and the width of the end of the pushing column 23 away from the active block one 20 is greater than the diameter of the second spring 24. The bottom end of the pushing column 23 is fixedly connected with a breaking column 25, and the breaking column 25 extends outside the second housing 16.

[0034] As an implementation manner of the present invention, the pushing device 9 is started, and then the first spring 22 is relaxed, that is, the active block one 20 is pushed to move towards the groove two 18. As the active block one 20 moves, the pushing column 23 will enter the groove four 21 formed on the active block one 20. Since the depth of the groove four 21 is less than the length of the pushing column 23, the active block one 20 will move along the pushing column 23 towards the direction of the breaking column 25, thereby squeezing the second spring 24. At the same time, the breaking column 25 will also move in the same direction to press the substrate 9 so as to deepen the crack on the substrate 9.

[0035] The stretching device 13 includes a rack block 26, a gear 27, a second fixing block 28, a first column 29, a third fixing block 30, a movable plate 31, a fifth groove 32, a support frame 33, a second column 34, and a second movable block 35; the second fixing block 28 is fixedly installed on the base 7, the first column 29 is fixedly connected to one side of the second fixing block 28 and they do not contact each other, the first column 29 extends onto the base 7, the rack block 26 is slidably connected to the second fixing block 28, a side of the rack block 26 close to the rotating disc 8 is fixedly connected to the fifth groove 32, support frames 33 are arranged on both sides of the fifth groove 32, a second movable block 35 is arranged between the support frames 33, the second movable block 35 is penetrated by a rolling shaft 36 and the rolling shaft 36 extends onto the support frames 33, a second column 34 is fixedly arranged at the top of the second movable block 35, the second column 34 extends into the fifth groove 32, the fourth fixing block the gear 27 is fixedly connected to the second fixing block 28, and the rack block 26 is meshed with the gear 27, one end of the gear 27 away from the base 7 is fixedly connected to a third fixing block 30, and the third fixing block 30 is also fixedly installed on the rack block 26, the third fixing block 30 penetrates through the first column 29, and a movable plate 31 is rotatably connected to a side of the third fixing block 30 close to the fifth groove 32.

[0036] As an implementation manner of the present invention, when the stretching device 13 is started, since the gear 27 is meshed with the rack block 26 and the gear 27 does not move, during movement, the rack block 26 moves towards the rotating disc 5, that is, the fifth groove 32 also moves towards its direction. And because the third fixing block 30 is located on the rack block 26, the third fixing block 30 is driven by the rack block 26 to move around the first column 29, and the movable plate 31 is fixedly connected to the third fixing block 30, so the movable plate 31 also moves around the first column 29. The two end movable plates 31 are symmetrical, so the movement directions are opposite, thus achieving the stretching effect. The second column 34 is fixedly installed inside the fifth groove 32, so the second column 34 makes a 90-degree rotational movement with the rolling shaft 36 as the center, and this can fix the movement track of the fifth groove 32, thereby defining the movement track of the rack block 26.

[0037] The bottom end of the first groove 17 is in an inverted trapezoidal shape, the width of the first movable block 20 is greater than the width of the short end of the inverted trapezoid, the width of the short end of the inverted trapezoid is less than the width of the second groove 18, the width of the second groove 18 is less than the width of the long end of the inverted trapezoid, and the width of the second groove 18 is less than the width of the third groove 19.

[0038] As an embodiment of the present invention, if the width of the first movable block 20 is smaller than the width of the short end of the inverted trapezoid, the first movable block 20 will slide into the second groove 18 and fail to achieve the limiting effect. Similarly, if the width of the short end of the inverted trapezoid is larger than the width of the second groove 18, the device cannot operate; if the width of the second groove 18 is larger than the width of the third groove 19, the pushing column 24 will directly pass through the second groove 18 until it reaches the first groove 17, and thus cannot play a role in limiting the pushing column 24, and the device cannot play a role in pushing the substrate 9.

[0039] Both sides of the support table 2 are fixedly installed with guide tubes 37, and the guide tubes 37 penetrate through the support table 2 and extend to both ends of the inner cavity of the first housing 1. One end of the support table 2 far from the rotating disc 8 is fixedly installed with a cylinder 38, and the cylinder 38 is located in the middle of the two guide tubes 37.

[0040] As an embodiment of the present invention, the function of the cylinder 38 is to adjust the height of the cutting blade 5 so as to better cut the substrate 9, and the function of the guide tube 37 is to guide the movement direction of the cylinder 38, so as to meet the requirement of adjusting the height of the cutting blade 5.

[0041] A rubber sleeve is sleeved on one end of the breaking column 25 far from the support table 2.

[0042] As an embodiment of the present invention, since the function of the breaking column 25 is to push the substrate 9, the breaking column 25 is in direct contact with the substrate 9, which may damage the surface of the substrate 9. If a rubber sleeve is sleeved, the pushing force of the breaking column 25 on the substrate 9 is relieved, and the possibility of damaging the substrate 9 is reduced.

[0043] The limiting block 10 is telescopic.

[0044] As an embodiment of the present invention, since the sizes of the substrates 9 are inconsistent, in order to better limit the position of the substrate 9, the position of the limiting block 10 is adjusted according to the size of the substrate 9 to determine the position of the substrate 9.

[0045] The pushing column 23 has an irregular shape, that is, it is in the shape of being narrower at the top and wider at the bottom. The diameter of one end of the pushing column 23 far from the first movable block 20 is larger than the diameter of the second spring 24.

[0046] As an embodiment of the present invention, the diameter of one end of the pushing column 23 far from the first movable block 20 is larger than the diameter of the second spring 24 to prevent the second spring 24 from falling into the pushing column 23, that is, to affect the effect generated during the operation of the device.

[0047] Specific working principle:

[0048] Before starting the device, place the substrate 9 on the rolling disc 5, then input the shape to be cut on the computer, and then start the device. The cylinder 38 controls the cutting blade 5 to move towards the rotating disc 8. While the cutting blade 5 is moving, the limit block 10 moves towards the corner of the substrate 9 until it coincides with the corner of the substrate 9 to limit the position of the substrate 9. After the position of the substrate 9 is determined, the cutting blade 5 cuts the substrate 9, and the rotating disc 8 starts to rotate counterclockwise evenly.

[0049] After cutting, the cylinder 38 controls the cutting blade to move towards the fixed panel 4. Then the telescopic tube 39 moves towards the rotating disc 5 until the pressing device 6 contacts the substrate 9. After that, the pressing device 9 is started, and then the first spring 22 is relaxed, which pushes the first movable block 20 towards the second groove 18. As the first movable block 20 moves, the pressing column 23 will enter the fourth groove 21 opened on the first movable block 20. Since the depth of the fourth groove 21 is less than the length of the pressing column 23, the first movable block 20 will move along the pressing column 23 towards the breaking column 25, thus squeezing the second spring 24. At the same time, the breaking column 25 will also move in the same direction to press the substrate 9 so as to deepen the crack on the substrate 9 to achieve the effect of breaking the substrate 9. When the breaking column 25 finishes pressing the substrate 9, a "Duang" sound will be heard. At this time, the stretching device 13 starts to operate, and the telescopic tube 39 starts to move towards the fixed panel 4, so that the pressing device 6 moves in the same direction until the telescopic tube 39 returns to the initial state. At this time, the pressing device 6 is also in the initial position.

[0050] When the stretching device 13 starts to operate, since the gear 27 is meshed with the rack block 26 and the gear 27 remains stationary, during movement, the rack block 26 moves towards the rotating disc 5, that is, the groove five 32 also moves in its direction. And because the fixed block three 30 is located on the rack block 26, the fixed block three 30 is driven by the rack block 26 to move around the column one 29, and the movable plate 31 is fixedly connected to the fixed block three 30, so the movable plate 31 also moves around the column one 29. The two movable plates 31 are symmetrical, so the movement directions are opposite, thus achieving the stretching effect. The column two 34 is fixedly installed inside the groove five 32, then the column two 34 rotates 90 degrees with the rolling shaft 36 as the center, and this can fix the movement trajectory of the groove five 32, thereby defining the movement trajectory of the rack block 26. Then the movable plates 31 pick up one end of the substrate 9 respectively, and then the rack block 26 moves in the direction away from the rotating disc 5, then the two movable plates 31 start to move counterclockwise around the column one 29, and the distance between the two movable plates 31 gradually increases. When the gear 28 reaches the end of the rack block 26, it starts to move in the direction close to the rotating disc 5, then the two movable plates 31 start to move clockwise around the column one 29, and at this time the distance between the two movable plates 31 gradually decreases until it returns to the initial state. Since the shapes of the substrate 9 to be cut are different, the rotating disc 5 needs to rotate counterclockwise to adjust the angle, and then the above operations are repeated until all the parts of the substrate 9 to be cut are completely separated.

[0051] When the stretching device 13 returns to the initial state, the electric telescopic tube 15 starts to move towards the rotating disc 5, then the grinding and cleaning rod 14 starts to move along the same path. While the grinding and cleaning rod 14 is moving, it starts to grind and clean the fracture parts of the substrate 9 on both sides. Since the substrate 9 may be cut into several small parts, it is necessary to start the rotating disc 5 to adjust the angle so that each fracture part of the substrate 9 can be ground and cleaned.

[0052] When all the fracture parts of the substrate 9 have been ground and cleaned, the limit block 10 starts to move in the direction away from the rotating disc 9 to return to the initial state. When the limit block 10 returns to the initial state, the whole device will make a "beep" sound, then at this time the staff can take the substrate 9, and this operation is to prevent the staff from being accidentally injured by the blade when taking the substrate 9.
