Description

Technical Field

[0001] The present invention relates to the technical field of microcrystalline glass detection, and in particular to a microcrystalline glass surface uniformity detection system. Background Art

[0002] In microcrystalline glass products, the surface uniformity is directly related to the overall quality of the product, especially in some special application scenarios, where the surface uniformity of microcrystalline glass is required to be high, such as the uniformity of the bonding surface of microcrystalline glass in certain scenarios. However, it is difficult to accurately detect the surface uniformity of microcrystalline glass with existing detection methods. Even if some equipment can complete the detection work, it is difficult to accurately mark the defect position (the position where the uniformity is unqualified) on the surface of microcrystalline glass, making the detection of microcrystalline glass surface uniformity difficult to perform.

[0003] In view of this, this application is hereby filed. Summary of the invention

[0004] The purpose of the present invention is to provide a microcrystalline glass surface uniformity detection system, which can accurately detect the surface uniformity of the microcrystalline glass and accurately mark the defect position during the detection, thereby greatly improving the efficiency and accuracy of defect detection and further ensuring the fineness of the microcrystalline glass products.

[0005] The embodiment of the present invention is achieved as follows:

[0006] A microcrystalline glass surface uniformity detection system comprises: a control core, a control cylinder, an ink supply component, an ink outlet tube and a positioning arm.

[0007] The control core includes a first core body and a second core body that are coaxially fixedly connected. The end of the first core body away from the second core body has a contact end for contacting the surface of the microcrystalline glass, and the contact end is smoothed. The first core body is provided with a connecting hole, which is arranged along the radial direction of the first core body and passes through the first core body. The outer wall of the second core body is provided with a groove, which extends along the axial direction of the second core body, and a pad is arranged in the groove.

[0008] The control core is slidably fitted in the control cylinder, one end of the control cylinder away from the contact end is closed by a sealing block, and a first elastic member is abutted between the control core and the sealing block.

[0009] The control cylinder is mounted on the positioning arm. A first matching groove and a second matching groove are provided on the inner side wall of one end of the control cylinder away from the sealing block. The first matching groove and the second matching groove are both arranged along the axial direction of the control cylinder and are arranged on opposite sides of the inner side wall of the control cylinder. The first matching groove and the second matching groove are of equal length, and are flush with each other in the axial direction of the control cylinder.

[0010] The side wall of the control cylinder is also provided with a control tube, which is arranged radially along the control cylinder, passes through the outer wall of the control cylinder to the inner wall thereof, and is located on the side of the second matching groove close to the sealing block.

[0011] The outer wall of the control cylinder is provided with an input tube penetrating into and communicating with the first matching groove, and the input tube is communicated with the ink supply assembly. The control cylinder is also provided with a connecting tube, one end of which is communicated with the control tube, and the other end of which is penetrating from the outer wall of the control cylinder to the second matching groove and communicated with the second matching groove.

[0012] The inlet end of the ink outlet tube is connected to the second matching groove, and the outlet end of the ink outlet tube is arranged close to the contact end. When the contact end contacts the surface of the microcrystalline glass, the outlet end of the ink outlet tube is close to the surface of the microcrystalline glass.

[0013] An annular groove is provided on the inner wall of the control tube, the annular groove is coaxially arranged with the control tube, and the annular groove extends along the axial direction of the control tube and penetrates to the end face of the control tube close to the control core. A control column is slidably fitted in the control tube, and a sliding seal is formed between the control column and the control tube. The control column has an annular flange, and a second elastic member is abutted between the annular flange and the end of the annular groove away from the control core.

[0014] The control core can slide relative to the control cylinder. When the connecting hole connects the first matching groove and the second matching groove, the end of the control column away from the connecting pipe abuts against the cushion block. When the first matching groove and the second matching groove are disconnected, the end of the control column away from the connecting pipe abuts against the bottom of the groove.

[0015] Before testing, adjust the distance between the positioning arm and the glass-ceramic to be tested so that the contact end abuts against the surface of the glass-ceramic to be tested, and the connecting hole can connect the first matching groove and the second matching groove. After the test starts, keep the distance between the positioning arm and the glass-ceramic to be tested unchanged, move the contact end along the surface of the glass-ceramic to be tested, and the ink outlet tube leaves an indicator line on the surface of the glass-ceramic to be tested. The position where the indicator line is interrupted is the defect position.

[0016] Furthermore, before testing, the distance between the positioning arm and the micro-ceramic glass to be tested is adjusted so that the connecting hole is located in the middle of the first matching groove and the second matching groove in the axial direction of the control core. The lengths of the first matching groove and the second matching groove are twice the maximum allowable error.

[0017] Furthermore, the contact end is cone-shaped. A clearance groove is provided at the tip of the contact end, the clearance groove extends along the axial direction of the control core, and the clearance groove also extends toward the back side of the contact end and penetrates the outer side wall of the contact end. The back side of the contact end is defined as: after the detection starts, when the contact end moves along the surface of the microcrystalline glass to be tested, the side of the contact end facing away from the moving direction.

[0018] The ink outlet tube is arranged in the give way groove and is coaxially arranged with the control core, and the ink outlet tube is communicated with the second matching groove through an output tube.

[0019] Furthermore, a sliding column is slidably fitted in the outlet end of the ink outlet tube, the sliding column and the ink outlet tube are slidably sealed, and a stopper for preventing the sliding column from falling out is provided at the mouth of the ink outlet tube.

[0020] The sliding column has an ink guide tube, which is coaxially arranged with the sliding column and penetrates the sliding column. The outer end of the ink guide tube is provided with a painting mechanism.

[0021] The writing mechanism comprises an elastic pen head.

[0022] The beneficial effects of the technical solution of the embodiment of the present invention include:

[0023] During the detection process of the microcrystalline glass surface uniformity detection system provided by the embodiment of the present invention, if a certain part of the surface of the microcrystalline glass to be tested is uneven, such as there is a protrusion or a depression, when the contact end moves to the corresponding defective position, the control core will move axially relative to the control cylinder, so that the connecting hole is axially displaced relative to the first matching groove and the second matching groove, and finally the connecting hole is staggered with the first matching groove and the second matching groove, resulting in the disconnection of the first matching groove and the second matching groove, which makes it impossible for the ink supply assembly to continue to supply ink to the ink outlet tube, and the indicator line is interrupted. The position where the indicator line is interrupted is the defective position. With this design, accurate detection and marking of the defective position can be achieved.

[0024] In addition, when the contact end moves to the defective position, the first matching groove and the second matching groove are disconnected, and the control column is also separated from the pad, and the control column further withdraws from the control tube. In this way, the control column acts as a piston, which can help to absorb the ink in the ink outlet tube into the second matching groove, thereby ensuring that the ink outlet tube stops discharging ink in time and preventing ink leakage.

[0025] When the contact end leaves the defective position, the connecting hole reconnects the first matching groove and the second matching groove, the control column moves to the pad again, and the control column further extends into the control tube. At this time, the control column can push the ink in the second matching groove into the ink outlet tube, thereby facilitating the ink outlet tube to discharge ink in time and avoiding the interruption distance being too long, which leads to a larger marking length of the defective position.

[0026] In general, the microcrystalline glass surface uniformity detection system provided in the embodiment of the present invention can accurately detect the surface uniformity of the microcrystalline glass, and can also accurately mark the defect location during detection, which greatly improves the efficiency and accuracy of defect detection and further ensures the fineness of the microcrystalline glass products.

[0047] Please refer to Figure 1 to Figure 11 This embodiment provides a microcrystalline glass surface uniformity detection system, which includes: a control core 100, a control cylinder 200, an ink supply assembly (not shown in the figure), an ink outlet tube 300 and a positioning arm 400.

[0048] The control core 100 includes a first core body 110 and a second core body 120 which are coaxially fixedly connected.

[0049] An end of the first core 110 away from the second core 120 has a contact end 111 for contacting the surface of the microcrystalline glass, and the surface of the contact end 111 is smoothed.

[0050] The first core 110 has a connecting hole 113 disposed along the radial direction of the first core 110 and passing through the first core 110. The outer wall of the second core 120 has a groove 121 extending along the axial direction of the second core 120, and a cushion block 122 is disposed in the groove 121.

[0051] The inner diameter of the control cylinder 200 is matched with the outer diameter of the control core 100, and the control core 100 can be slidably fitted in the control cylinder 200, and a sliding seal is formed between the inner wall of the control cylinder 200 and the outer wall of the first core body 110. The end of the control cylinder 200 away from the contact end 111 is closed by the sealing block 210, and a first elastic member 220 is abutted between the control core 100 and the sealing block 210. An anti-slip mechanism (not shown in the figure) is provided at the end of the control cylinder 200 away from the sealing block 210 to prevent the control core 100 from completely slipping out.

[0052] The control cylinder 200 is mounted on the positioning arm 400 , and the positioning arm 400 may be a mechanical arm, but is not limited thereto.

[0053] The inner side wall of the control cylinder 200 at one end away from the sealing block 210 is provided with a first matching groove 230 and a second matching groove 240, which are both arranged along the axial direction of the control cylinder 200 and are arranged on opposite sides of the inner side wall of the control cylinder 200. The first matching groove 230 and the second matching groove 240 are of equal length, and in the axial direction of the control cylinder 200, the first matching groove 230 and the second matching groove 240 are flush.

[0054] The side wall of the control cylinder 200 is also provided with a control tube 250 , which is arranged along the radial direction of the control cylinder 200 . The control tube 250 penetrates from the outer wall of the control cylinder 200 to its inner wall. The control tube 250 is located on the side of the second matching groove 240 close to the sealing block 210 .

[0055] The outer wall of the control cylinder 200 is provided with an input tube 260 penetrating into and communicating with the first matching groove 230. The input tube 260 is communicated with the ink supply assembly, and the ink supply assembly is used to deliver ink into the first matching groove 230 according to a preset pressure through the input tube 260. The ink is an easy-to-clean ink type.

[0056] The control cylinder 200 is further provided with a connecting pipe 270 , one end of which is connected to the control pipe 250 , and the other end of which passes through the outer wall of the control cylinder 200 to the second matching groove 240 and is connected to the second matching groove 240 .

[0057] The inlet end of the ink outlet tube 300 is connected to the second matching groove 240, and the outlet end of the ink outlet tube 300 is arranged close to the contact end 111. When the contact end 111 contacts the surface of the microcrystalline glass, the outlet end of the ink outlet tube 300 is close to the surface of the microcrystalline glass.

[0058] An annular groove is provided on the inner wall of the control tube 250, and the annular groove is coaxially arranged with the control tube 250, and the annular groove extends along the axial direction of the control tube 250 and penetrates to the end surface of the control tube 250 close to the control core 100. A control column 251 is slidably fitted in the control tube 250, and a sliding seal is formed between the control column 251 and the control tube 250. The control column 251 has an annular flange 252, and a second elastic member 253 is abutted between the annular flange 252 and the end of the annular groove away from the control core 100. The control column 251 is used to cooperate with the groove 121.

[0059] The control core 100 can slide relative to the control cylinder 200. Along the circumference of the control core 100, the control core 100 and the control cylinder 200 are in a fixed matching relationship. The connecting hole 113 is used to connect the first matching groove 230 and the second matching groove 240. When the control core 100 slides axially relative to the control cylinder 200, the end of the control column 251 away from the connecting tube 270 slides in the groove 121.

[0060] When the connecting hole 113 connects the first matching groove 230 and the second matching groove 240, the control column 251 slides to the cushion block 122, and the end of the control column 251 away from the connecting tube 270 abuts against the cushion block 122. At this time, the control column 251 further extends into the control tube 250. When the first matching groove 230 and the second matching groove 240 are disconnected, the control column 251 leaves the cushion block 122, and the end of the control column 251 away from the connecting tube 270 abuts against the bottom of the groove 121. At this time, the control column 251 further extends out of the control tube 250.

[0061] Before testing the glass-ceramic 500 to be tested, the spacing between the positioning arm 400 and the glass-ceramic 500 to be tested can be changed by adjusting the positioning arm 400, thereby changing the spacing between the control cylinder 200 and the glass-ceramic 500 to be tested. Optionally, during adjustment, the control cylinder 200 and the control core 100 are both perpendicular to the surface of the glass-ceramic 500 to be tested, and the positioning arm 400 is adjusted so that the contact end 111 abuts against the surface of the glass-ceramic 500 to be tested. After the contact end 111 contacts the surface of the glass-ceramic 500 to be tested, the control core 100 is pushed into the control cylinder 200, and the connecting hole 113 is able to connect the first matching groove 230 and the second matching groove 240.

[0062] After the detection starts, the distance between the positioning arm 400 and the microcrystalline glass 500 to be tested is kept unchanged, and the contact end 111 moves along the surface of the microcrystalline glass 500 to be tested. Under normal circumstances, the ink outlet tube 300 can leave an indication line on the surface of the microcrystalline glass 500 to be tested.

[0063] If a certain part of the surface of the micro-ceramic glass 500 to be tested is uneven, such as there is a bulge or depression, when the contact end 111 moves to the corresponding defective position, the control core 100 will move axially relative to the control cylinder 200, so that the connecting hole 113 is axially displaced relative to the first matching groove 230 and the second matching groove 240, and finally the connecting hole 113 is staggered with the first matching groove 230 and the second matching groove 240, resulting in the disconnection of the first matching groove 230 and the second matching groove 240, which makes it impossible for the ink supply component to continue to supply ink to the ink outlet tube 300, and the indicator line is interrupted. The position where the indicator line is interrupted is the defective position.

[0064] Through this design, accurate detection and marking of defect locations can be achieved.

[0065] In addition, when the contact end 111 moves to the defective position, the first mating groove 230 and the second mating groove 240 are disconnected, and the control column 251 is also separated from the pad 122, and the control column 251 further withdraws from the control tube 250. In this way, the control column 251 acts as a piston, which can help to absorb the ink in the ink outlet tube 300 into the second mating groove 240, thereby ensuring that the ink outlet tube 300 stops discharging ink in time and preventing ink leakage.

[0066] When the contact end 111 leaves the defective position, the connecting hole 113 reconnects the first matching groove 230 and the second matching groove 240, and the control column 251 moves to the pad 122 again, and the control column 251 further extends into the control tube 250. At this time, the control column 251 can push the ink in the second matching groove 240 into the ink outlet tube 300, thereby facilitating the ink outlet tube 300 to discharge ink in time and avoiding the interruption distance being too long, which causes the marking length of the defective position to be too large.

[0067] In general, the microcrystalline glass surface uniformity detection system provided in this embodiment can accurately detect the surface uniformity of the microcrystalline glass, and can also accurately mark the defect location during detection, which greatly improves the efficiency and accuracy of defect detection and further ensures the fineness of the microcrystalline glass products.

[0068] In this embodiment, before testing the microcrystalline glass 500 to be tested, the distance between the positioning arm 400 and the microcrystalline glass 500 to be tested is adjusted so that in the axial direction of the control core 100, the connecting hole 113 is located in the middle of the first matching groove 230 and the second matching groove 240. The lengths of the first matching groove 230 and the second matching groove 240 can be set to twice the maximum allowable error. In this way, the defect position exceeding the maximum allowable error can be sensitively detected. Through this design, the maximum allowable error can be flexibly adjusted to formulate different detection rules for different application scenarios.

[0069] Furthermore, the contact end 111 is conical. A clearance groove 112 is provided at the tip of the contact end 111, and the clearance groove 112 extends along the axial direction of the control core 100, and the clearance groove 112 also extends toward the back side of the contact end 111 and penetrates the outer side wall of the contact end 111. The back side of the contact end 111 is defined as: after the detection starts, when the contact end 111 moves along the surface of the microcrystalline glass 500 to be tested in the direction K, the side of the contact end 111 facing away from the moving direction. The direction K refers to: the direction in which the control core 100 moves relative to the surface of the microcrystalline glass during the detection process.

[0070] The ink outlet tube 300 is disposed in the clearance groove 112 and is coaxially fixed with the control core 100 . The ink outlet tube 300 and the second matching groove 240 are connected by the output tube 350 .

[0071] With this design, when the ink outlet tube 300 leaves an indication line on the surface of the microcrystalline glass 500 to be tested, the contact end 111 will not damage the indication line and will not adhere to ink, thereby ensuring the integrity and accuracy of the indication line and avoiding interference lines caused by ink adhering to the contact end 111.

[0072] Furthermore, a sliding post 320 is slidably fitted in the outlet end of the ink outlet tube 300 , and a sliding seal is formed between the sliding post 320 and the ink outlet tube 300 . A stopper 310 is provided at the mouth of the ink outlet tube 300 to prevent the sliding post 320 from falling out.

[0073] The sliding column 320 has an ink guide tube 330, which is coaxially arranged with the sliding column 320 and passes through the sliding column 320. The outer end of the ink guide tube 330 is provided with a writing mechanism 340. The writing mechanism 340 can adopt an elastic pen tip, such as the pen tip of a beauty pen, but is not limited thereto.

[0074] Through this design, when the connecting hole 113 connects the first matching groove 230 and the second matching groove 240, under the joint action of the control column 251 and the ink supply assembly, the sliding column 320 can slide outward in time to extend the writing mechanism 340, making it easier for the writing mechanism 340 to leave an indication line on the surface of the microcrystalline glass 500 to be tested.

[0075] When the first matching groove 230 and the second matching groove 240 are disconnected, under the "re-sucking" effect of the control column 251, the sliding column 320 slides inward, and the writing mechanism 340 is retracted in time, while avoiding ink leakage. This not only ensures the writing quality of the indicator line, but also improves the writing accuracy of the indicator line and avoids the appearance of interference lines.

[0076] To sum up, the microcrystalline glass surface uniformity detection system provided in the embodiment of the present invention can accurately detect the surface uniformity of the microcrystalline glass, and can also accurately mark the defect location during detection, which greatly improves the efficiency and accuracy of defect detection and further ensures the fineness of the microcrystalline glass products.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
