[0028] Please see Figures 1-9This utility model provides a technical solution for a glass surface stress detector, including a detector body 1, which is the instrument for actually detecting the glass surface. A detection area 8 is installed on the upper surface of the detector body 1, which is the placement area for the glass to be tested and requires the application of developing solution. A pushing component 5 and a liquid supply component 3 are respectively provided on the front and rear sides inside the detector body 1. The pushing component 5 moves the lifting component 7 (described below) a certain distance. The liquid supply component 3 provides developing solution for glass surface stress detection. The liquid supply component 3 includes a storage tank 31, a delivery pipe 33, and a peristaltic pump 32. The storage tank 31 contains developing solution. After the peristaltic pump 32 operates, it drives the delivery pipe 33 to transmit the developing solution from the storage tank 31. The pushing component 5 includes a first electric telescopic rod 51, and the output end of the first electric telescopic rod 51 is provided with a lifting component 7. The lifting component 7 controls the lifting of the dripping component 4, allowing the dripping component 4 to enter and exit the detector body 1. The lifting component 7 includes a third electric telescopic rod 71. The telescopic mechanism drives the dropper assembly 4 to rise and fall. The output end of the third electric telescopic rod 71 is equipped with the dropper assembly 4, which drips the developing solution onto the detection area 8. The dropper assembly 4 includes a mounting frame 43, on which a dropper tank 41 is movably mounted. The dropper tank 41 temporarily stores the developing solution. The dropper tank 41 is connected to the storage tank 31 through an infusion tube 33. A flipping assembly 6 is installed on the side wall of the mounting frame 43. The flipping assembly 6 rotates the dropper tank 41 from a horizontal state to a vertical state. The vertical dropper tank 41... 1. A developing solution can be dripped onto the surface of the detection area 8. The flipping assembly 6 includes a second electric telescopic rod 61 and a flipping frame 62 movably connected thereto. The flipping frame 62 is connected to the dripping tank 41. The extension and retraction of the second electric telescopic rod 61 drives the flipping frame 62 to rotate. The flipping frame 62 drives the dripping tank 41 to rotate. When the flipping frame 62 rotates, it drives the dripping tank 41 to flip. The lifting assembly 7 pushes the dripping assembly 4 to rise, and the pushing assembly 5 pushes the dripping assembly 4 above the detection area 8. The flipping assembly 6 flips the dripping assembly 4 to drip the solution.

[0029] The entire dripping assembly 4 is pushed out of the detector body 1 by the third electric telescopic rod 71 in the lifting assembly 7. The pushing assembly 5 pushes the lifting assembly 7 and other components, so that the dripping assembly 4 moves above the detection area 8. After the flipping frame 62 in the flipping assembly 6 flips the dripping tank 41, the dripping tank 41 is adjusted to a vertical position. For the specific state, refer to [reference needed]. Figure 2 and Figure 4 After the peristaltic pump 32 in the liquid supply assembly 3 starts working, it transfers the developer in the storage tank 31 through the liquid delivery pipe 33. The amount of developer pumped by the peristaltic pump 32 each time is set according to the actual type of glass being tested. The developer is transferred to the inside of the dripping tank 41, and the dripping tank 41 drips the developer onto the surface of the test 8 to complete the quantitative dripping of the developer in the test area.

[0030] In use, the third electric telescopic rod 71 extends to push the various components of the dripping device to the outside, completing the longitudinal position adjustment of the dripping device 4. The first electric telescopic rod 51 in the push assembly 5 extends to push the dripping device 4 above the detection area 8. When the second electric telescopic rod 61 retracts, it drives the flipping frame 62 to rotate. When the flipping frame 62 rotates, it drives the dripping tank 41 to flip vertically. After the peristaltic pump 32 works, it delivers the developing solution into the interior of the dripping tank 41 through the infusion tube 33 and drips it onto the surface of the detection area 8.

[0031] like Figure 3 As shown, the liquid supply assembly 3 includes a base 34, which supports the liquid storage tank 31. The base 34 is installed inside the detector 1. The liquid storage tank 31 is installed on the base 34. The liquid storage tank 31 contains developing solution, which is used for glass surface stress detection. One end of the infusion tube 33 is installed on the liquid storage tank 31. The infusion tube 33 is used to transfer the developing solution inside the liquid storage tank 31. After the peristaltic pump 32 is working, the infusion tube 33 draws out the developing solution inside the liquid storage tank 31. The peristaltic pump 32 draws out a fixed amount of developing solution each time. The amount of developing solution drawn out by the peristaltic pump 32 each time is set according to the actual type of glass being tested. The peristaltic pump 32 is installed on the outer wall of the infusion tube 33.

[0032] When the peristaltic pump 32 is powered on, the driving force generated inside it squeezes the infusion tube 33 to draw the developer solution from the inside of the storage tank 31 for delivery. The amount of developer solution drawn by the peristaltic pump 32 each time is between 10 ml and 20 ml, thereby realizing the transfer of the developer solution.

[0033] Combination Figure 3 and Figure 5 The pushing component 5 includes a base frame 52, which mounts the first electric telescopic rod 51 and is also used to open the slide groove 56. A bracket 53 is installed on the rear of the upper surface of the base frame 52, which supports the first electric telescopic rod 51. The slide groove 56 is opened at the front of the base frame 52. The first electric telescopic rod 51 is mounted on the bracket 53. One end of a crank 55 is installed at the output end of the first electric telescopic rod 51. The crank 55 moves with the first electric telescopic rod 51. Using the crank 55 as a medium, the third electric telescopic rod 71 moves. A slide rod 54 is installed at the bottom of the crank rod 55. The slide rod 54 is slidably engaged with the slide groove 56. After the first electric telescopic rod 51 extends, the slide rod 54 slides inside the slide groove 56.

[0034] After the first electric telescopic rod 51 extends, it drives the crank rod 55 to move. The crank rod 55 drives the third electric telescopic rod 71 to move, so as to push the dripping component 4 to the top of the detection area 8. The crank rod 55 drives the slide rod 54 to slide inside the slide groove 56. Under the dynamic support effect of the slide rod 54 sliding, the stability of the first electric telescopic rod 51 in pushing the movement of each structure is increased.

[0035] likeFigures 3 to 6 As shown, the third electric telescopic rod 71 in the lifting assembly 7 is used to move the dripping assembly 4 in and out of the detector body 1, that is, it is responsible for the positioning and retraction of the dripping assembly 41. The bottom of the third electric telescopic rod 71 is connected to the other end of the crank 55. The output end of the third electric telescopic rod 71 is equipped with a lifting frame 72, which is the bearing component of the dripping assembly 4.

[0036] When the third electric telescopic rod 71 extends, it pushes out the lifting frame 72. The lifting frame 71 lifts the dripping component 4 loaded on it out of the detector body 1 for dripping. When the third electric telescopic rod 71 retracts, it allows the dripping component 4 to retract and be stored.

[0037] like Figures 3 to 6 As shown, the dripping assembly 4 includes a mounting frame 43, which is the basic structure of the dripping assembly 4. The mounting frame 43 is mounted on the support frame 72. Both ends of the front part of the mounting frame 43 are equipped with collars 44, which allow the sleeve rods 46 to be inserted. The connection between the two can rotate. A sleeve 45 is provided at the center of the mounting frame 43. The sleeve 45 contains a dripping tank 41 with a volume of 20 ml, which is used to initially store the developer. Sleeve rods 46 are fixed to both sides of the outer wall of the sleeve 45. The sleeve rods 46 are inserted into the collars 44, which allows the sleeve 45 to rotate on the mounting frame 43. The dripping tank 41 is installed inside the sleeve 45. A miniature solenoid valve 42 is installed on the dripping tank 41. The solenoid valve 42 controls the flow of the developer inside the dripping tank 41. One end of a connecting rod 47 is installed on the outer end face of the sleeve rod 46. The other end of the connecting rod 47 is connected to the flipping frame 62. The connecting rod 47 is the medium connecting the sleeve rod 46 and the flipping frame 63.

[0038] like Figures 5 to 7 As shown, the flipping assembly 6 includes a support frame 64, which provides a mounting carrier for the second electric telescopic rod 61. One end of the support frame 64 is mounted on the mounting frame 43, and the other end of the support frame 64 is movably mounted with the second electric telescopic rod 61. The second electric telescopic rod 61 is the power source for the flipping of the dripping assembly 4. A connecting cylinder 63 is fixedly connected to the output end of the second electric telescopic rod 61. The connecting cylinder 63 is movably connected to the mounting rod 67, allowing the second electric telescopic rod 61 to be movably connected to the flipping frame 62, preventing jamming when the second electric telescopic rod 61 pulls the flipping frame 62. The mounting rod 67 is inserted inside the connecting cylinder 63 and is located inside the flipping frame 62. Rollers 66 are mounted at both ends of the mounting rod 67. When the second electric telescopic rod 61 extends or retracts, the rollers 66 slide inside the wheel groove 65 with the displacement of the mounting rod 67. See the reference for details. Figure 8 The inner wall of the tilting frame 62 has a wheel groove 65, and the roller 66 slides and engages with the wheel groove 65.

[0039] like Figure 6As shown, under normal conditions, the second electric telescopic rod 61 is in the extended state, the tilting frame 62 is in the vertical state, and the dripping tank 41 is also in the horizontal state. When the dripping tank 41 needs to be reversed, the second electric telescopic rod 62 retracts, pulling the connecting cylinder 63 to rotate on the outer wall of the mounting rod 67. The mounting rod 67 drives the roller 66 to slide inside the wheel groove 65, causing the tilting frame 62 to rotate to an inclined state. See the reference for details. Figure 7 The flipping frame 62 drives the sleeve rod 46 to rotate via the connecting rod 47, so that the sleeve 45 and the dripping tank 41 rotate to complete the flipping.

[0040] Combination Figure 1 , Figure 2 and Figure 9 The rear part of the detection area 8 is provided with a capping assembly 2 on the upper surface of the detector body 1. The capping assembly 2 seals the opening of the dripping assembly 4. The capping assembly 2 includes a cap 21 and a stop block 22. When the cap 21 is in the capping state, the bottom is blocked by the stop block 22. When the dripping assembly 4 is raised, the cap 21 is rotated and opened, and the dripping is exposed outside the detector body 1. The cap 21 is movably connected to the upper surface of the detector body 1. The stop block 22 is located at the bottom of the cap 21 and is installed on the detector body 1. The cap 21 is in contact with the stop block 22.

[0041] To increase the wear resistance of the infusion tubing 33 when squeezed by the peristaltic pump 32, the infusion tubing 33 is made of polyurethane rubber.

[0042] The working principle of this utility model is explained below with reference to a preferred embodiment: After the peristaltic pump 32 is energized, the driving force generated inside it squeezes the infusion tube 33 to draw the developer solution from the inside of the storage tank 31 for delivery. The amount of developer solution drawn by the peristaltic pump 32 each time is set according to the actual type of glass being tested. The infusion tube 33 initially transfers a fixed amount of developer solution into the drip tank 41. When the third electric telescopic rod 71 extends, it pushes out the lifting frame 72. After the first electric telescopic rod 51 extends, it drives the crank 55 to move. The crank 55 drives the third electric... The telescopic rod 71 is displaced to push the dripping assembly 4 to the top of the detection area 8. When the second electric telescopic rod 62 is retracted, it pulls the connecting cylinder 63 to rotate on the outer wall of the mounting rod 67. The mounting rod 67 drives the roller 66 to slide inside the wheel groove 65, causing the flipping frame 62 to rotate to an inclined state. The flipping frame 62 drives the sleeve rod 46 to rotate through the connecting rod 47, so that the sleeve 45 and the dripping tank 41 rotate to complete the flipping. The flipping assembly 6 changes the rotation of the dripping tank 41 from a straight state to a vertical state. After the solenoid valve 42 is opened, the developing solution is dripped onto the detection area 8.
