The first controller controls the refractive liquid titration mechanism and the stress detector to operate in sequence according to the received incoming material information, so as to titrate the refractive liquid on the upper surface of the detection stage and perform stress detection on the surface of the glass.

[0011] Furthermore, the refractive liquid titration mechanism includes:

[0015] The rotary cylinder can drive the connecting rod to move from the first position to the second position, so that the outlet of the burette moves above the detection stage, so as to drip the refractive liquid onto the upper surface of the detection stage.

[0016] Furthermore, the glass surface stress testing equipment also includes a sorting and discharging device, which includes a qualified product discharging line, an NG product discharging line, and a transfer mechanism.

[0030] The second sensor is used to sense the glass information above the material tray and transmit the sensed glass information to the second controller.

[0031] Furthermore, the second control module also includes a third sensor, which and the first lifting drive assembly are electrically connected to the second controller.

[0032] The third sensor is used to sense the position information of the material support plate and transmit the sensed position information to the second controller. The second controller controls the first lifting drive component to start according to the received position information.

[0035] A plurality of correction mechanisms, including cylinders, support frames and grippers, wherein the cylinders are fixedly arranged circumferentially along the edge of the correction platform, the support frame is fixedly connected to the output end of the cylinders, and the grippers are fixedly arranged on the support frame; the cylinders are capable of driving the support frame and the grippers to move radially along the correction platform.

[0036] Furthermore, both the feeding device and the correction feeding device include a moving module and a robotic arm, and the feeding device and the correction feeding device share one moving module.

[0037] Furthermore, the glass surface stress testing equipment also includes a correction table moving mechanism.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0045] This invention provides a glass surface stress detection device, the structure of which is as follows: Figure 1 and Figure 2 As shown, the device includes a stress detection device 1, a loading device 2, a unloading device 3, and a first control module. The stress detection device 1 includes a testing platform 11, a stress detector 12, and a refractive liquid titration mechanism 13. The loading device 2 is used to transfer the glass slide to be tested to the testing station of the testing platform 11. The unloading device 3 is used to remove the tested glass slide from the testing platform 11. The first control module includes a first sensor 20 and a first controller. The first sensor 20 and the refractive liquid titration mechanism 13 are electrically connected to the first controller.

[0046] The first sensor 20 is used to sense the incoming material information of the feeding device 2 and transmit the sensed incoming material information to the first controller. The first controller controls the refractive liquid titration mechanism 13 and the stress detector 12 to operate sequentially according to the received incoming material information, so as to titrate the refractive liquid on the upper surface of the detection stage 11 and perform stress detection on the surface of the glass.

[0047] In the glass surface stress detection equipment, the first control module can control the refractive liquid titration mechanism 13 and the stress detector 12 to operate sequentially according to the material information of the feeding device 2, so as to titrate the refractive liquid on the upper surface of the detection table 11 and perform stress detection on the glass surface, thereby realizing the automated operation of glass surface stress detection and enabling batch glass surface stress detection.

[0048] For details, please refer to Figure 2 The refractive liquid titration mechanism 13 includes a rotary cylinder 131, a connecting rod 132, and a burette 133. The rotary cylinder 131 is fixedly disposed on the outside of the detection stage 11. One end of the connecting rod 132 is fixedly connected to the output end of the rotary cylinder 131. The burette 133 is fixedly disposed on the other end of the connecting rod 132 and is connected to an external refractive liquid supply device.

[0049] The rotary cylinder 131 can drive the connecting rod 132 from a first position to a second position, so that the outlet of the burette 133 moves above the detection stage 11 to drip the refractive liquid onto the upper surface of the detection stage 11. Specifically, when the connecting rod 132 is in the first position, it is located on the outer side above the detection stage 11; when the connecting rod 132 is in the second position, it is located directly above the detection station of the detection stage 11.

[0050] Understandably, after the refractive liquid titration is completed, the rotary cylinder 131 can drive the connecting rod 132 to move from the second position to the first position, so that the burette 133 located directly above the detection station of the detection platform 11 is moved to the outside of the detection platform 11, so as to avoid the connecting rod 132 and the burette 133 interfering with the operation of the stress detector 12.

[0051] In order to classify and output the qualified and NG products, such as Figure 3As shown, in a preferred embodiment, the glass surface stress testing equipment further includes a sorting and discharging device 4, which includes a qualified product discharging line 41, an NG product discharging line 42, and a transfer mechanism 43. The transfer mechanism 43 is used to transfer the glass sheet to the qualified product discharging line 41 or the NG product discharging line 42 according to the detection result of the stress detector 12.

[0052] In a specific embodiment, the qualified product discharge line 41 and the NG product discharge line 42 are arranged side by side. The transfer mechanism 43 includes a third lifting drive assembly 431, a transverse movement assembly 432, and a bracket 433. The third lifting drive assembly 431 is fixedly arranged below the NG product discharge line 42. The transverse movement assembly 432 is fixedly arranged at the output end of the third lifting drive assembly 431. The bracket 433 is fixedly arranged at the output end of the transverse movement assembly 432.

[0053] Specifically, in this embodiment, the initial position of the bracket 433 is above the NG product discharge line 42. When the stress detector 12 shows an NG result, the feeding device 3 transfers the tested glass sheet to the bracket 433. The third lifting drive assembly 431 drives the lateral movement assembly 432 and the bracket 433 to descend until the glass sheet on the bracket 433 falls onto the NG product discharge line 42. When the stress detector 12 shows a qualified result, the feeding device 3 transfers the tested glass sheet to the bracket 433. The lateral movement assembly 432 drives the bracket 433 to move laterally above the qualified product discharge line 41. Then, the third lifting drive assembly 431 operates to drive the bracket 433 to descend until the glass sheet on the bracket 433 falls onto the qualified product discharge line 41.

[0054] For a batch of glass sheets, since the number of NG (non-quality) items is small, the NG items can be buffered. In a preferred embodiment, the sorting and discharging device 4 further includes an NG item buffering mechanism 44. The NG item buffering mechanism 44 includes a support plate 441, two sets of comb-shaped grids 442, and a first lifting drive assembly 443. The support plate 441 is movably disposed below the discharge side of the NG item discharge line 42. The two sets of comb-shaped grids 442 are disposed opposite to each other on the upper surface of the support plate 441. The spacing between the two sets of comb-shaped grids 442 matches the width of the glass sheet, and there are at least two comb-shaped grids 442 in each set. Each comb-shaped grid 442 has several grid slots arranged from top to bottom, and the thickness of the grid slots is not less than the thickness of the glass sheet. The glass sheet can be placed across the grid slots of the two sets of comb-shaped grids 442. The first lifting drive assembly 443 is fixedly disposed below the support plate 441, and the output end of the first lifting drive assembly 443 is fixedly connected to the support plate 441.

[0055] For each NG (no good) item detected by the stress detector 12, the first lifting drive assembly 443 drives the support plate 441 to rise by the thickness of one grid slot, thereby switching the grid slot containing the glass sheet. Specifically, the initial position of the comb-shaped grid 442 is such that its top is flush with the NG item discharge line 42.

[0056] It is understandable that by setting up the NG product buffer mechanism 44, the NG products that appear can be stored one by one in the grid slot, replacing manual material collection and improving the efficiency of NG product collection.

[0057] It should be noted that in some embodiments, the NG (Not Found) product buffer mechanism 44 is only used as an emergency storage mechanism. Normally, NG products are output along the NG product discharge line 42 and collected at the end of the NG product discharge line 42. In order to successfully collect NG products at the end of the NG product discharge line 42, as a preferred embodiment, the sorting and discharging device 4 further includes a material blocking mechanism 45. The material blocking mechanism 45 includes a material support plate 451, a second lifting drive assembly 452, and a second control module 453. The material support plate 451 is movably disposed below the discharge end of the NG product discharge line 42. The second lifting drive assembly 452 is fixedly disposed below the material support plate 451, and the output end of the second lifting drive assembly 452 is fixedly connected to the material support plate 451. The second control module 453 includes a second sensor and a second controller. The second sensor and the second lifting drive assembly 452 are electrically connected to the second controller.

[0058] The second sensor is used to sense the glass information above the material tray 451 and transmit the sensed glass information to the second controller. The second controller controls the second lifting drive assembly 452 to start according to the received glass information, so that the material tray 451 rises to lift the glass sheet above it from the NG product discharge line 42, making it easier to collect the material from the material tray 451. Specifically, the second sensor is fixedly installed on the upper surface of the material tray 451.

[0059] Understandably, when a glass sheet passes above the material support plate 451, the second lifting drive assembly 452 can drive the material support plate 451 to rise and lift the glass sheet above it from the NG product discharge line 42, so as to prevent the glass sheet from continuing to move on the NG product discharge line 42, and facilitate the removal of the glass sheet from the NG product discharge line 42.

[0060] In order to achieve linkage between the material blocking mechanism 45 and the NG product buffer mechanism 44, in a preferred embodiment, the second control module 453 further includes a third sensor, and the third sensor and the first lifting drive assembly 443 are electrically connected to the second controller respectively;

[0061] The third sensor is used to sense the position information of the material support plate 451 and transmit the sensed position information to the second controller. The second controller controls the first lifting drive component 443 to start according to the received position information.

[0062] It is understood that when the material tray 451 is in the lifted state (the material tray 451 contains NG products), the second controller can control the first lifting drive assembly 443 to start, thereby causing the comb grid 442 to rise by the thickness of one grid slot, thereby collecting the NG products.

[0063] Since the stress detector 12 has high accuracy requirements for the position of the glass piece to be tested, in order to improve the positional accuracy of the glass piece to be tested, such as... Figure 1 and Figure 4 As shown, in a preferred embodiment, the glass surface stress detection equipment further includes a correction device 5 and a correction unloading device 6. The correction device 5 is used to correct and center the glass sheet picked up by the loading device 2 to facilitate stress monitoring. The correction unloading device 6 is used to pick up the corrected and centered glass sheet and transfer it to the detection station of the detection table 11.

[0064] The correction device 5 includes a correction platform 51 and several correction mechanisms 52. The correction platform 51 is fixedly disposed between the detection platform 11 and the feeding device 2. The glass sheet gripped by the feeding device 2 is placed on the upper surface of the correction platform 51. The correction mechanism 52 includes a cylinder 521, a support frame 522, and a gripper 523. Several cylinders 521 are fixedly disposed along the circumference of the correction platform 51 at the edge of the correction platform 51. The support frame 522 is fixedly connected to the output end of the cylinder. The gripper 523 is fixedly disposed on the support frame 522. The cylinder 521 can drive the support frame 522 and the gripper 523 to move radially along the correction platform 51.

[0065] It is understood that the cylinder 521 can drive the corresponding support frame 522 and the gripper 523 to move, so that the grippers 523 move closer and further apart. After the grippers 523 move closer together, the position and angle of the glass piece located in the middle of the grippers 523 can be adjusted to complete the correction operation of the glass piece.

[0066] It should be noted that the extension and retraction of the piston rod of the cylinder 521 to move the support frame 522 and the gripper 523 is only a preferred embodiment of this scheme. In other embodiments, the cylinder 521 can also be replaced by a hydraulic cylinder or an electric push rod.

[0067] In a preferred embodiment, the upper surface of the alignment table 51 is provided with a mounting groove, and the first sensor 20 is fixedly installed in the mounting groove. When the first sensor 20 senses the glass information on the alignment table 51, the first sensor 20 transmits a signal to the first controller. The first controller controls the rotary cylinder 131 to move according to the received glass information, so as to move the connecting rod 132 from the first position to the second position, so that the outlet of the burette 133 moves above the detection table 11, and the refractive liquid is dripped on the upper surface of the detection table 11.

[0068] Please continue to refer to Figure 1 As a specific embodiment, both the feeding device 3 and the correction feeding device 6 include a moving module and a robotic arm. In order to reduce the size of the equipment, the feeding device 3 and the correction feeding device 6 share a single moving module.

[0069] Since the loading device 2 and the correction and unloading device 6 need to transfer the glass sheet to the correction table 51 and move the corrected glass sheet from the correction table 51 to the testing table 11, in order to ensure that the loading device 2 and the correction and unloading device 6 avoid each other, in a preferred embodiment, the glass surface stress testing equipment further includes a correction table moving mechanism 7. The correction table 51 is movably disposed between the testing table 11 and the loading device 2. The output end of the correction table moving mechanism 7 is fixedly connected to the correction table 51 and is used to drive the correction table 51 from a first position to a second position, so that the robotic arms of the loading device 2 and the correction and unloading device 6 avoid each other.

[0070] To facilitate understanding of the present invention, the following is combined with... Figures 1-4 The working principle of this solution will be explained in detail:

[0071] During operation, the feeding device 2 places the glass slides to be tested one by one on the upper surface of the alignment table 51. Several cylinders 521 are activated simultaneously, driving the corresponding support frame 522 and the gripper 523 to move towards the center of the upper surface of the alignment table 51. The several converging grippers 523 can correct and align the glass slides. When the first sensor 20 senses the glass slide information on the upper surface of the alignment table 51, the first controller controls the rotary cylinder 131 to move. Through the connecting rod 132, the burette 133 is moved to move its outlet to directly above the detection station of the detection table 11. The burette 133 then drips refractive liquid at the detection station.

[0072] After the correction is completed, the correction feeding device 6 is activated to grab the corrected glass sheet and transfer it to the testing station on the upper surface of the testing table 11. The stress detector 12 is activated to detect the surface stress of the glass sheet in the testing station. There are two types of detection structures: qualified and NG.

[0073] After the inspection is completed, the unloading device 3 starts to grab the inspected glass sheet and transfer it to the bracket 433. Then, according to the inspection result, the glass sheet will be moved to the qualified product discharge line 41 or the NG product discharge line 42. Specifically, when the inspection result of the stress detector 12 shows NG, the unloading device 3 transfers the inspected glass sheet to the bracket 433, and the third lifting drive component 431 drives the transverse component 432 and the bracket 433 to descend. The glass sheet on the bracket 433 falls onto the NG (Not Good) product discharge line 42. When the stress detector 12 shows a qualified result, the unloading device 3 transfers the tested glass sheet onto the bracket 433. The lateral movement component 432 moves the bracket 433 laterally above the qualified product discharge line 41. Then, the third lifting drive component 431 lowers the bracket 433 until the glass sheet on the bracket 433 falls onto the qualified product discharge line 41. The qualified product discharge line 41 and the NG product discharge line 42 will output qualified and NG glass sheets to the next process respectively.

[0074] When NG glass sheets are conveyed on the NG product discharge line 42, when the second sensor senses the glass information above the material support plate 451, the second sensor transmits the sensed glass information to the second controller. The second controller controls the second lifting drive assembly 452 to start according to the received glass information, so that the material support plate 451 rises to lift the glass sheet above it from the NG product discharge line 42, and the worker or robot will collect the material from the material support plate 451.

[0075] When the material support plate 451 is in the raised state (when the glass sheet on the upper surface of the material support plate 451 is not retracted), the second controller controls the first lifting drive assembly 443 to start, thereby causing the comb-shaped grid 442 to rise by the thickness of one grid slot, thereby buffering and collecting NG products.

[0076] The glass surface stress detection device provided by this invention has the following beneficial effects:

[0077] (1) The first control module can control the refractive liquid titration mechanism 13 and the stress detector 12 to operate sequentially according to the material information of the feeding device 2, so as to titrate the refractive liquid on the upper surface of the detection table 11 and perform stress detection on the surface of the glass, thereby realizing the automated work of glass surface stress detection and enabling batch glass surface stress detection work.

[0078] (2) After the refractive liquid titration is completed, the rotary cylinder 131 can drive the connecting rod 132 to move from the second position to the first position, so that the burette 133 located directly above the detection station of the detection table 11 can be moved to the outside of the detection table 11, so as to avoid the connecting rod 132 and the burette 133 interfering with the operation of the stress detector 12.

[0079] (3) By setting the NG product buffer mechanism 44, the NG products can be stored layer by layer in the grid groove, replacing manual material collection and improving the efficiency of NG product glass sheet collection.

[0080] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
