Description

Technical Field

[0001] This invention relates to the field of glass scribing technology, and more particularly to a glass scribing tool assembly, equipment, and method. Background Technology

[0002] Currently, cover glass requires multiple scribing and cutting processes during production to obtain the finished product of the required size. The glass cutting method usually involves first scribing the glass surface with a scribing knife, and then breaking the glass to achieve the cutting.

[0003] However, when existing scribing blades are used to scribing thicker glass, the blades may break off due to the greater resistance they encounter, resulting in low scribing efficiency. Furthermore, the blades that fly off during the breakage pose a significant safety hazard. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention proposes a glass scribing tool assembly, device, and method.

[0005] This invention proposes a glass scribing tool assembly, comprising a first plate, a first tool unit, a second tool unit, and a third tool unit. The first tool unit, the second tool unit, and the third tool unit are mounted on the first plate and arranged sequentially along a first direction. Specifically, the first tool unit includes a first tool head and a first tool holder; the first tool head is fixed to the first tool holder, and the first tool holder is fixed to the first plate. The second tool unit specifically includes a second tool head, a second tool holder, and a first adjustment mechanism; the second tool head is fixedly mounted on the second tool holder, and the second tool holder is mounted on the first plate via the first adjustment mechanism. The first adjustment mechanism operates to move the scribing end of the second tool head closer to or further away from the first plate along a second direction. The third tool unit specifically includes a third tool head, a third tool holder, and a second adjustment mechanism; the third tool head is fixedly mounted on the third tool holder, and the third tool holder is mounted on the first plate via the second adjustment mechanism. The second adjustment mechanism operates to move the scribing end of the third tool head closer to or further away from the first plate along a second direction, where the first direction is perpendicular to the second direction.

[0006] Preferably, the first adjustment mechanism includes a first mounting block, a first screw, a first limiting member, and a first washer. The first screw is helically connected to a threaded hole on the first mounting block along a second direction, and the bottom end of the first screw is also fixed with a first limiting member extending radially therefrom. The first washer is sleeved on the first screw and located between the first mounting block and the first limiting member, and the first washer is fixedly connected to the second tool holder by fastening bolts. A first rectangular through hole is opened on the first plate body along the second direction. The first mounting block and the second tool holder are slidably inserted into the first rectangular through hole, and the first mounting block and the first plate body are fixedly connected by fastening bolts.

[0007] Preferably, the second adjustment mechanism includes a second mounting block, a second screw, a second limiting member, and a second washer. The second screw is helically connected to a threaded hole on the second mounting block along a second direction, and the bottom end of the second screw is also fixed with a second limiting member extending radially therefrom. The second washer is sleeved on the second screw and located between the second mounting block and the second limiting member, and the second washer is fixedly connected to the second tool holder by fastening bolts. The first plate has a second rectangular through hole arranged along the second direction. The second mounting block and the second tool holder are slidably inserted into the second rectangular through hole, and the second mounting block is fixedly connected to the first plate by fastening bolts.

[0008] The present invention proposes a glass scribing device, including the above-mentioned blade assembly, and further including: a second plate, a first driving mechanism, and a second driving mechanism. The second driving mechanism drives the second plate to move along a first direction, and the second plate is fixedly connected to the first plate to drive the first plate to move closer to or away from the second plate along a second direction.

[0009] The present invention also proposes a scribing method for scribing glass using the above-mentioned scribing equipment, comprising the following steps:

[0010] S1. Adjust the positions of the second cutter head and the third cutter head in the second direction using the first adjustment mechanism and the second adjustment mechanism respectively;

[0011] S2, The second drive mechanism drives the first plate to move along the second direction;

[0012] S3. The first drive mechanism drives the second plate to move along the first direction, and the first cutter head, the second cutter head, and the third cutter head move together with the second plate along the first direction to scribing the glass.

[0013] Preferably, the first adjusting mechanism drives the second cutter head to move so that the scribing end of the second cutter head is coplanar with the scribing end of the first cutter head, and the second adjusting mechanism drives the third cutter head to move so that the scribing end of the third cutter head is coplanar with the scribing end of the first cutter head.

[0014] Preferably, the first adjusting mechanism drives the second cutter head to move so that the scribing end of the second cutter head is above the scribing end of the first cutter head, and the second adjusting mechanism drives the third cutter head to move so that the scribing end of the third cutter head is above the scribing end of the first cutter head, and the scribing ends of the second cutter head and the third cutter head are coplanar.

[0015] Preferably, the first adjustment mechanism drives the second cutter head located at the front end of the movement to move such that the scribing end of the second cutter head is below the scribing end of the first cutter head, and the second adjustment mechanism drives the third cutter head located at the rear end of the movement to move such that the scribing end of the third cutter head is above the scribing end of the first cutter head.

[0016] Preferably, the distance between the second cutting head scribing end and the top wall of the glass to be cribing in the second direction is L1, the height difference between the first cutting head scribing end and the second cutting head scribing end in the second direction is L2, and the height difference between the third cutting head scribing end and the first cutting head scribing end in the second direction is L3, where L1 = L2 = L3.

[0017] The positions of the second and third cutting heads in the glass scribing head assembly proposed in this invention can be adjusted according to specific usage requirements. Specifically, the scribing ends of the second and third cutting heads can be coplanar with the scribing end of the first cutting head to jointly scribing the glass. The scribing ends of the second and third cutting heads can be adjusted to be above the first cutting head. The second or third cutting head is at the front end of the scribing process to perform the first scribing process on the glass, and the first cutting head is at the rear end of the scribing process to perform the second scribing process on the glass. This distributes the external force originally borne by one cutting head to multiple cutting heads, thereby reducing the possibility of chipping when scribing thicker glass.

[0022] Figure 5 This is a flowchart of a glass scribing method proposed in this invention. Detailed Implementation

[0023] Reference Figure 1The present invention proposes a glass scribing blade assembly, comprising a first plate 1, a first blade unit 2, a second blade unit 3, and a third blade unit 4. The first blade unit 2, second blade unit 3, and third blade unit 4 are mounted on the first plate 1 and arranged sequentially along a first direction. Specifically, the first blade unit 2 includes a first blade head 21 and a first blade holder 22, with the first blade head 21 fixed to the first blade holder 22, which in turn is fixed to the first plate 1. The second blade unit 3 specifically includes a second blade head 31, a second blade holder 32, and a first adjusting mechanism 33. The second blade head 31 is fixedly mounted on the first plate 1. The second tool holder 32 is mounted on the first plate 1 via the first adjustment mechanism 33. The first adjustment mechanism 33 is activated to drive the scribing end of the second tool head 31 to move closer to or away from the first plate 1 along the second direction. The third tool unit 4 specifically includes: a third tool head 41, a third tool holder 42, and a second adjustment mechanism 43. The third tool head 41 is fixedly mounted on the third tool holder 42. The third tool holder 42 is mounted on the first plate 1 via the second adjustment mechanism 43. The second adjustment mechanism 43 is activated to drive the scribing end of the third tool head 41 to move closer to or away from the first plate 1 along the second direction. The first direction is perpendicular to the second direction.

[0024] When the glass 5 to be scribed is relatively thin, the second cutting head 31 and the third cutting head 41 are adjusted to state one by the first adjusting mechanism 33 and the second adjusting mechanism 43 respectively, so that the scribing ends of the second cutting head 31 and the third cutting head 41 are coplanar with the scribing end of the first cutting head 21. See [reference needed] for details. Figure 2 At this time, the first cutter head 21, the second cutter head 31 and the third cutter head 41 work together to scribing the glass 5 to be scribed. Even if one of the cutter heads is damaged, the other two cutter heads can still perform scribing without affecting the scribing process.

[0025] When the glass 5 to be scribed is relatively thick, if only one cutter head is used for cutting, the cutting depth will be relatively deep, and the cutter head will experience greater resistance during the scribing process, making it easy for the glass to break. In this case, the cutter assembly proposed in this invention can adjust the scribing ends of the second cutter head 31 and the third cutter head 41 to be above the scribing end of the first cutter head 21.

[0026] For details, please refer to Figure 3The second cutter head 31 and the third cutter head 41 are adjusted to state two by the first adjustment mechanism 33 and the second adjustment mechanism 43 respectively. When the cutter assembly moves from right to left to scribble on the glass 5 to be scribbled, the second cutter head 31 is located at the moving front end of the first cutter head 21. The second cutter head 31 first scribbles on the glass 5 to be scribbled for the first time, and the scribing depth is half of the preset scribing depth of the glass 5 to be scribbled. Then the first cutter head 21 scribbles on the scratches after the first scribble. The distance between the scribing end of the first cutter head 21 and the top wall of the glass 5 to be scribbled is the same as the preset scribing depth of the glass 5 to be scribbled. The scribbles are performed in batches in the second direction to reduce the risk of chipping and can be scribbled repeatedly. When moving from left to right, the third cutter head 41 is located at the moving front end and performs the first scribble.

[0027] You can also refer to Figure 4 The second cutter head 31 and the third cutter head 41 are adjusted to state three by the first adjustment mechanism 33 and the second adjustment mechanism 43 respectively. When drawing lines from left to right, the drawing end of the second cutter head 31 at the front end of the movement is above the drawing end of the first cutter head 21, and the drawing end of the third cutter head 41 at the rear end of the movement is below the drawing end of the first cutter head 21. The second cutter head 31 performs the first drawing on the glass 5 to be drawn, the first cutter head 21 performs the second drawing on the slit after the second cutter head 31, and finally the third cutter head 41 performs the third drawing on the glass 5 to be drawn. The distance between the drawing end of the second cutter head 31 and the top wall of the glass 5 to be drawn in the second direction is L1, the height difference between the drawing end of the first cutter head 21 and the drawing end of the second cutter head 31 in the second direction is L2, and the height difference between the drawing end of the third cutter head 41 and the drawing end of the first cutter head 21 in the second direction is L3. L1 = L2 = L3.

[0028] In the above embodiment, the first adjustment mechanism 33 includes a first mounting block 331, a first screw 332, a first limiting member 333, and a first washer 334. The first screw 332 is screwed to a threaded hole on the first mounting block 331 along the second direction, and the bottom end of the first screw 332 is also fixed with a first limiting member 333 extending radially therefrom. The first washer 334 is sleeved on the first screw 332 and located between the first mounting block 331 and the first limiting member 333. The first washer 334 is fixedly connected to the second tool holder 32 by fastening bolts. The first plate 1 has a first rectangular through hole 11 arranged along the second direction. The first mounting block 331 and the second tool holder 32 are slidably inserted into the first rectangular through hole 11, and the first mounting block 331 is fixedly connected to the first plate 1 by fastening bolts.

[0029] When assembling the second tool unit 3, the second tool holder 32 and the second tool head 31 are inserted into the first rectangular through hole 11 along the second direction. Then, the first mounting block 331 is fixedly connected to the first plate 1 by fastening bolts. The assembly method is simple and quick, and it is convenient to install and disassemble.

[0030] Furthermore, since the second tool holder 32 is restricted by the first rectangular through hole 11 and will not move together with the first screw 332, the second tool holder 32 is driven to move up and down in the second direction by the first limiting member 333 and the first washer 334, thereby adjusting the position of the scribing end of the second tool holder 32 in the second direction. In addition, the second tool holder 32 is adapted to be inserted into the first rectangular through hole 11. During the scribing process, the hole wall of the first rectangular through hole 11 can provide a supporting force to the second tool holder 32, thereby making the second tool unit 3 more secure during use.

[0031] The second adjustment mechanism 43 includes a second mounting block 431, a second screw 432, a second limiting member 433, and a second washer 434. The second screw 432 is helically connected to a threaded hole on the second mounting block 431 along the second direction. The bottom end of the second screw 432 is also fixed with a second limiting member 433 extending radially therefrom. The second washer 434 is sleeved on the second screw 432 and located between the second mounting block 431 and the second limiting member 433. The second washer 434 is fixedly connected to the second tool holder 32 by fastening bolts. The first plate 1 has a second rectangular through hole 12 arranged along the second direction. The second mounting block 431 and the second tool holder 32 are slidably inserted into the second rectangular through hole 12. The second mounting block 431 is fixedly connected to the first plate 1 by fastening bolts.

[0032] The adjustment process of the second adjustment mechanism 43 is the same as that of the first adjustment mechanism 33.

[0033] The present invention also proposes a glass scribing device, including the above-mentioned blade assembly, and further including: a second plate, a first driving mechanism, and a second driving mechanism. The second driving mechanism drives the second plate to move along a first direction, and the second plate is fixedly connected to the first plate 1 to drive the first plate 1 to move closer to or away from the second plate along a second direction.

[0034] Reference Figure 5 The present invention also proposes a marking method for marking glass using the above-mentioned marking equipment, comprising the following steps:

[0035] S1. The positions of the second cutter head 31 and the third cutter head 41 in the second direction are adjusted by the first adjustment mechanism 33 and the second adjustment mechanism 43, respectively.

[0037] Example 2: The first adjustment mechanism 33 drives the second cutter head 31 to move so that the scribing end of the second cutter head 31 is above the scribing end of the first cutter head 21. The second adjustment mechanism 43 drives the third cutter head 41 to move so that the scribing end of the third cutter head 41 is above the scribing end of the first cutter head 21, and the scribing ends of the second cutter head 31 and the third cutter head 41 are coplanar.

[0038] Example 3: The first adjustment mechanism 33 drives the second cutter head 31 to move so that the scribing end of the second cutter head 31 is above the scribing end of the first cutter head 21. The second adjustment mechanism 43 drives the third cutter head 41 to move so that the scribing end of the third cutter head 41 is below the scribing end of the first cutter head 21. The distance between the scribing end of the second cutter head 31 and the glass top wall in the second direction is L1. The height difference between the scribing end of the first cutter head 21 and the scribing end of the second cutter head 31 in the second direction is L2. The height difference between the scribing end of the third cutter head 41 and the scribing end of the first cutter head 21 in the second direction is L3. L1 = L2 = L3.

[0039] S2, the second drive mechanism drives the first plate 1 to move along the second direction.
