Description

Technical Field

[0001] The present invention relates to the technical field of glass quality inspection, and specifically to a flipping device for glass processing and inspection. Background Art

[0002] During the glass processing and inspection process, it is usually necessary to flip the glass to complete processes such as double-sided inspection, cleaning, coating, or surface treatment. The flipping devices on the market are often set on the conveying device, adsorb the glass surface through suction cups, and use the rotating mechanism to drive the suction cups to flip the glass. Such devices achieve flipping by adsorbing and fixing the glass and rotating around an axis, meeting the basic requirements.

[0003] However, the functions of such devices are relatively single and cannot meet the diverse needs of glass position adjustment in complex processing scenarios. The currently common flipping devices have obvious deficiencies. First of all, they lack an effective clamping and protection function for the glass. Only relying on suction cup adsorption and fixation, when flipping at high speed or when the glass surface has oil stains or is uneven, it is easy for the glass to slip due to insufficient adsorption force, resulting in potential safety hazards and a decrease in the yield rate.

[0004] Secondly, the existing devices cannot adjust the direction of the glass during the flipping process, resulting in the need for manual secondary adjustment when the glass reaches the next process, reducing the automation efficiency. In addition, the linkage between the lifting and flipping mechanisms of the existing devices is poor, making it difficult to achieve precise control of first vertically lifting the glass and then flipping it, and it is easy for the glass to collide with the conveying device, resulting in the glass being skewed or even falling off. Summary of the Invention

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a flipping device for glass processing and inspection, including a lifting mechanism arranged on the conveying device, and a flipping frame rotatably arranged inside the lifting mechanism. A suction cup is arranged at one end of the flipping frame far away from the U-shaped frame. The device also includes a direction adjustment mechanism for rotating the glass when flipping the glass, and a protection mechanism for clamping and protecting the glass.

[0006] The lifting mechanism includes a U-shaped frame that slides up and down in the middle of the conveying device.

[0007] The direction adjustment mechanism includes a C-shaped ring frame fixedly installed at one end of the flipping frame far away from the U-shaped frame. A support plate is fixedly installed on the C-shaped ring frame. A transmission shaft is rotatably arranged between the support plate and the flipping frame. The transmission shaft drives the suction cup to rotate when the glass is flipped through a gear transmission method.

[0008] The protection mechanism includes a linkage plate rotatably arranged at the lower end outside the suction cup. Telescopic arms are hinged on both the left and right sides of the linkage plate. A clamping frame is hinged at one end of the telescopic arm far away from the suction cup. A cylinder is arranged between the clamping frame and the corresponding telescopic arm.

[0009] The lifting mechanism drives the suction cup to adsorb on the glass through the flipping frame. Subsequently, the lifting mechanism vertically lifts the glass, and the cylinder drives the clamping frame to clamp and protect the glass. Then, the flipping frame is rotated, and the glass is rotated according to requirements. Finally, it vertically descends and places the glass.

[0010] As a preferred technical solution of the present invention, the lifting mechanism further includes a driven gear fixedly installed on the front side of the rotating shaft of the flipping frame. A rack meshing with the driven gear is slidably arranged up and down inside the U-shaped frame. A hydraulic cylinder is arranged between the lower end of the rack and the conveying device, and a spiral spring is arranged between the telescopic section of the hydraulic cylinder and the U-shaped frame.

[0011] As a preferred technical solution of the present invention, locking blocks are slidably arranged left and right on the upper side of the horizontal section of the U-shaped frame. A pushing spring is arranged between the locking blocks and the U-shaped frame. Locking grooves for the locking blocks to insert are arranged on the rack. A T-shaped plate fixedly connected to the conveying device is arranged on the left part of the U-shaped frame.

[0012] As a preferred technical solution of the present invention, a round rod is rotatably arranged on the locking block. A right ring part and a left ring part for automatically locking the round rod are fixedly installed on the upper side of the horizontal section of the U-shaped frame. The round rod is jointly and movably inserted into the coaxial positions inside the right ring part and the left ring part.

[0013] As a preferred technical solution of the present invention, four circular plates rotatably connected to it are arranged at equal intervals in the vertical direction inside the C-shaped ring frame. The circular plates are jointly fixedly connected to the suction cup. Semi-circular grooves spaced 90 degrees apart are sequentially opened on the outer sides of the circular plates from bottom to top. A moving block is slidably arranged up and down inside the opening of the C-shaped ring frame. A limiting post is slidably arranged in the radial direction of the circular plate inside the moving block.

[0014] As a preferred technical solution of the present invention, a compression spring is arranged between the limiting post and the moving block. Rectangular grooves corresponding to the circular plates one by one are opened at the opening position of the C-shaped ring frame. A locking member is slidably arranged back and forth on the moving block. A return spring is arranged between the locking member and the moving block.

[0015] As a preferred technical solution of the present invention, a transmission bevel gear is fixedly installed at one end of the transmission shaft close to the U-shaped frame. Three bevel gear segments arranged at equal intervals in the circumferential direction of the rotation of the flipping frame are slidably arranged back and forth through a guiding square rod on the vertical section at the rear of the U-shaped frame.

[0016] As a preferred technical solution of the present invention, two arc-shaped slots arranged front and back are opened on the guiding square rod. An arc-shaped inserting rod for inserting into the arc-shaped slots is rotatably arranged inside the vertical section at the rear of the U-shaped frame. The arc-shaped inserting rod is locked together with the U-shaped frame through a fastening screw.

[0017] As a preferred technical solution of the present invention, the telescopic arm includes a hinged section hinged to the linkage plate and a sliding section slidably connected to the hinged section along the length direction thereof. A screw rod is fixedly installed on the hinged section and slides inside the sliding section, and a knob threadedly connected to the screw rod is rotatably provided on the sliding section.

[0018] As a preferred technical solution of the present invention, rollers are rotatably provided on both the sliding section and the side of the clamping frame away from the cylinder. A fixed ring member is fixedly installed on the support plate, the fixed ring member is rotatably connected to the linkage plate, and an arc-shaped spring is provided between the fixed ring member and the linkage plate.

[0019] The beneficial effects of the present invention are as follows: First, the present invention adopts a protection mechanism. Through the coordinated action of the linkage plate, the telescopic arm and the cylinder, after the suction cup adsorbs and lifts the glass, the edge of the glass is automatically clamped, effectively preventing the adsorption failure caused by high-speed flipping or oil stains and unevenness on the glass surface, significantly improving the operation safety and the yield rate. Moreover, by pre-adjusting the length of the telescopic arm, it can also adapt to glasses of different sizes.

[0020] Second, the present invention adopts an orientation adjustment mechanism. Through the gear transmission design of the transmission shaft, the suction cup is synchronously driven to drive the glass to rotate and adjust the orientation during the flipping process, realizing the precise adjustment of the glass angle, avoiding secondary manual intervention, greatly improving the automation efficiency. Moreover, by adjusting the number of meshing of the transmission bevel gear and the bevel gear section, the glass can also be rotated by different angles to adapt to different detection and processing requirements.

[0021] Third, the present invention adopts the linkage design of the lifting mechanism and the flipping frame. After the hydraulic cylinder drives the U-shaped frame to vertically lift the glass and then perform the flipping action, and then vertically place the glass on the conveying device, ensuring that there is no collision between the glass and the conveying device during the flipping, avoiding the glass from being skewed or falling, and improving the processing accuracy.

[0022] Fourth, the present invention adopts a multi-stage locking structure, such as the locking cooperation between the locking block and the locking groove of the rack, and the limiting mechanism of the limiting column and the semi-circular groove of the circular plate, enhancing the operation stability of each mechanism, preventing accidental displacement caused by vibration during the flipping or lifting process, and ensuring the long-term reliability of the equipment.

Specific Embodiments

[0033] The embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention. For those not specified in the embodiments regarding specific techniques or conditions, they shall be carried out according to the techniques or conditions described in the literature in this field or according to the product specifications.

[0034] Refer to Figure 1 and Figure 2 , a flipping device for glass processing and detection, including a lifting mechanism 1 arranged on a conveying device, and a flipping frame 2 rotatably arranged inside the lifting mechanism 1. One end of the flipping frame 2 away from the U-shaped frame 11 is provided with a suction cup 3. The device further includes an orientation mechanism 4 for rotating the glass when flipping the glass, and a protection mechanism 5 for clamping and protecting the glass.

[0035] When it is necessary to flip the glass on the conveying device, the lifting mechanism 1 drives the flipping frame 2 to move the suction cup 3 to the upper side of the glass. Subsequently, the glass is adsorbed by the suction cup 3, and then the lifting mechanism 1 drives the suction cup 3 to vertically lift the glass. At the same time, the glass is clamped and protected by the protection mechanism 5. Then, the lifting mechanism 1 drives the suction cup 3 to flip half a circle, so that the suction cup 3 drives the glass to turn over.

[0036] During the flipping process of the glass, the orientation adjustment mechanism 4 rotates the suction cup 3 according to a preset rotation angle, so that the suction cup 3 and the protection mechanism 5 rotate the glass together. Then, the lifting mechanism 1 drives the flipped glass to vertically descend until the glass is placed on the conveying device. During the vertical descent of the glass, the protection mechanism 5 automatically unlocks the glass and rotates back to its original position.

[0037] After that, the lifting mechanism 1 drives the flipping frame 2 to reset. During the rotation and reset of the flipping frame 2, the orientation adjustment mechanism 4 can automatically reverse the suction cup 3, so that the suction cup 3 returns to the initial angle, facilitating the rotation and orientation adjustment of the glass again.

[0038] It should be noted that when detecting the surface quality of both sides of the glass, the glass needs to be flipped. The image sensor automatically identifies scratches and cracks on the glass surface, and the infrared sensor can identify dirt or foreign objects on the glass surface.

[0039] The principle of the image sensor to identify scratches and cracks is as follows: The light source illuminates the glass surface, the camera captures the image of the glass surface through the lens, converts it into an electrical signal, and then the image acquisition card converts the electrical signal into a digital image signal and transmits it to the computer. The image processing software analyzes and processes the acquired image, and identifies abnormal features in the image through algorithms, thereby identifying the surface defects of the glass.

[0040] Continue to refer to Figure 1 and Figure 2 As shown, the lifting mechanism 1 includes a U-shaped frame 11 that slides up and down in the middle of the conveying device. A driven gear 12 is fixedly installed on the front side of the rotating shaft of the flipping frame 2. A rack 13 that meshes with the driven gear 12 is slidably arranged up and down inside the U-shaped frame 11. A hydraulic cylinder 14 is arranged between the lower end of the rack 13 and the conveying device. A spiral spring is arranged between the telescopic section of the hydraulic cylinder 14 and the U-shaped frame 11.

[0041] Refer to Figure 2 、 Figure 3 and Figure 4 As shown, locking blocks 15 are slidably arranged left and right on the upper side of the horizontal section of the U-shaped frame 11. A pushing spring is arranged between the locking blocks 15 and the U-shaped frame 11. Locking grooves for the locking blocks 15 to insert are arranged on the rack 13. A T-shaped plate 16 fixedly connected to the conveying device is arranged on the left part of the U-shaped frame 11.

[0042] Refer to Figure 3 、 Figure 4 and Figure 5 As shown in FIGS.

[0043] In the initial state, the suction cup 3 is located at the left part of the hydraulic cylinder 14, and the spiral spring is in an extended state, so that the spiral spring pushes the U-shaped frame 11 upward away from the hydraulic cylinder 14 by its own elastic force. It should be noted that a sector member is fixedly installed at the rear side of the rotating shaft of the turning frame 2, and a limiting member is fixedly installed at the front side of the rear horizontal section of the U-shaped frame 11 and corresponding to the position of the sector member. In the initial state, the turning frame 2 drives the sector member to rotate above the right part of its rotating shaft, and makes the sector member abut against the limiting member, which makes the turning frame 2 unable to deflect to the left at this time.

[0044] In this embodiment, the inclined surface structures on the sides of the right ring member 152 and the left ring member 153 close to each other are arranged at equal intervals along the circumferential direction of the round rod member 151. The inclined surface structures on the right ring member 152 and the left ring member 153 are symmetrically arranged. There are four inclined surface structures on the right ring member 152 and the left ring member 153, and the inclined surfaces on the right ring member 152 and the left ring member 153 are staggered by 45 degrees. A linear waist-shaped groove penetrating up and down and horizontally is formed on the left ring member 153. Two symmetrically arranged convex columns are fixedly installed on the outer side of the right end of the round rod member 151, and the right end of the linear waist-shaped groove communicates with the leftmost point of the inclined surface structure at the corresponding position on the left ring member 153.

[0045] In the initial state, the two convex columns are respectively located at the leftmost positions inside the corresponding linear waist-shaped grooves, so that at this time, the pushing spring pushes the locking block 15 to the left part of the rack 13 by its own elastic force. And in the initial state, the locking groove on the rack 13 is located below the locking block 15. Since the turning frame 2 cannot deflect to the left anymore, the rack 13 cannot move downward relative to the driven gear 12.

[0046] When the conveying device moves the glass to directly below the suction cup 3, the telescopic section of the hydraulic cylinder 14 is contracted, so that the hydraulic cylinder 14 drives the rack 13 to move downward. The rack 13 drives the turning frame 2 and the U-shaped frame 11 to move downward synchronously through the driven gear 12. The turning frame 2 drives the suction cup 3 to move downward until it abuts against the upper side of the glass, and adsorbs the glass through the suction cup 3.

[0047] Refer to Figure 2 and Figure 7, the protection mechanism 5 includes a linkage plate 51 rotatably arranged at the lower end outside the suction cup 3. Telescopic arms 52 are hinged on both the left and right sides of the linkage plate 51. A clamping bracket 53 is hinged at the end of the telescopic arm 52 away from the suction cup 3. A cylinder 54 is arranged between the clamping bracket 53 and the corresponding telescopic arm 52.

[0048] Refer to Figure 7 , the telescopic arm 52 includes a hinged section 521 hinged on the linkage plate 51, and a sliding section 522 slidably connected to the hinged section 521 along the length direction of the hinged section 521. A screw 523 sliding inside the sliding section 522 is fixedly installed on the hinged section 521. A knob 524 threadedly connected to the screw 523 is rotatably arranged on the sliding section 522.

[0049] Continue to refer to Figure 7 , rollers 55 are rotatably arranged on both the sliding section 522 and the side of the clamping bracket 53 away from the cylinder 54. A fixed ring member 56 is fixedly installed on the support plate 43. The fixed ring member 56 is rotatably connected to the linkage plate 51. An arc spring is arranged between the fixed ring member 56 and the linkage plate 51.

[0050] In the initial state, the arc spring pushes the linkage plate 51 through its own elastic force, so that the linkage plate 51 drives the two telescopic arms 52 to be arranged left and right, and the two telescopic arms 52 naturally droop under the action of gravity. It should be noted that a limit block is fixedly installed at the connection between the hinged section 521 and the linkage plate 51, and the limit block is not shown in the figure. By blocking the hinged section 521 with the limit block, the two telescopic arms 52 are arranged in an inverted V shape in the naturally drooping state.

[0051] When the suction cup 3 moves vertically downward, the suction cup 3 drives the roller 55 on the clamping bracket 53 to abut against the upper side of the glass through the linkage plate 51 and the telescopic arm 52. Subsequently, the suction cup 3 continues to move downward, so that the reaction force of the glass on the roller 55 on the clamping bracket 53 pushes the clamping bracket 53 upward, thereby making the clamping bracket 53 drive the angle between the two telescopic arms 52 to gradually increase, and at the same time, the clamping bracket 53 moves towards the edge position of the glass.

[0052] When the clamping bracket 53 drives the roller 55 thereon to move beyond the edge position of the glass, the telescopic arm 52 swings downward under the action of gravity and drives the roller 55 thereon to move to the outside of the glass through the clamping bracket 53. When it is necessary to flip glasses of different sizes, the operator can manually rotate the knob 524 in advance to make the knob 524 drive the sliding section 522 to slide along the length direction of the hinged section 521, thereby changing the overall length of the telescopic arm 52 and further adapting to glasses of different sizes.

[0053] It should be noted that when the roller 55 outside the glass does not abut against the conveying device, the sliding section 522 drives the roller 55 thereon to abut against the upper side of the glass by its own gravity, so that the clamping frame 53 drives the roller 55 thereon to move to the lower part of the glass. When the roller 55 outside the glass abuts against the conveying device, the roller 55 on the sliding section 522 does not contact the upper side of the glass.

[0054] Subsequently, extend the telescopic section of the hydraulic cylinder 14, so that the hydraulic cylinder 14 drives the rack 13 to move upward. At the same time, the hydraulic cylinder 14 pushes the U-shaped frame 11 to move upward together with the rack 13 through the spiral spring, so that the rack 13 does not drive the driven gear 12 to rotate, thereby enabling the suction cup 3 to drive the glass to move vertically upward synchronously.

[0055] When the glass moves upward until it does not contact the conveying device, the roller 55 that originally abutted against the conveying device becomes suspended, so that the sliding section 522 drives the roller 55 thereon to abut against the upper side of the glass by its own gravity. At this time, the two clamping frames 53 drive the rollers 55 thereon to move to the lower part of the glass. Subsequently, extend the telescopic section of the air cylinder 54 to push the deflection of the clamping frame 53, so that the clamping frame 53 drives the roller 55 thereon to move to the lower right part of the glass, and the clamping frame 53 clamps the glass, thereby clamping and protecting the glass through the clamping frame 53, and protecting the lower side of the glass through the roller 55 on the clamping frame 53.

[0056] It should be noted that the lower side of the vertical section of the T-shaped plate 16 has an inclined surface structure that gradually inclines to the left from top to bottom. When the U-shaped frame 11 drives the locking block 15 to move onto the inclined surface mechanism of the T-shaped plate 16, the T-shaped plate 16 pushes the locking block 15 to the right through the inclined surface thereon, so that the locking block 15 abuts against the rack 13, and at this time the locking block 15 still contacts the inclined surface of the T-shaped plate 16, so that the locking block 15 is blocked by the T-shaped plate 16 and cannot move upward, thereby causing the locking block 15 to block the U-shaped frame 11 from continuing to move upward.

[0057] Subsequently, continue to extend the telescopic section of the hydraulic cylinder 14, so that the rack 13 drives the driven gear 12 to rotate, and at the same time compress the spiral spring, and the driven gear 12 drives the glass to rotate synchronously through the flipping frame 2.

[0058] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in

[0059] Refer to Figure 7 andFigure 8 Inside the C-shaped ring frame 41, four circular plates 411 rotatably connected thereto are equidistantly arranged in the vertical direction. The circular plates 411 are fixedly connected to the suction cup 3 together. Semi-circular grooves spaced 90 degrees apart are successively formed on the outer sides of the circular plates 411 from bottom to top. A moving block 412 is slidably arranged up and down inside the opening of the C-shaped ring frame 41, and a limiting post 413 is slidably arranged radially along the circular plate 411 inside the moving block 412.

[0060] Continue to refer to Figure 7 and Figure 8 A compression spring is arranged between the limiting post 413 and the moving block 412. Rectangular grooves corresponding to the circular plates 411 one by one are formed at the opening position of the C-shaped ring frame 41. A locking member 414 is slidably arranged back and forth on the moving block 412, and a return spring is arranged between the locking member 414 and the moving block 412.

[0061] The operator first moves the moving block 412 up and down as needed, so that the limiting post 413 on the moving block 412 corresponds to the appropriate position of the circular plate 411. Subsequently, the operator manually slides the locking member 414 into the rectangular groove at the corresponding position, and the elastic force of the return spring prevents the locking member 414 from withdrawing from the rectangular groove under external force.

[0062] Specifically, when it is not required to rotate the glass after flipping, the moving block 412 is made to correspond to the lowermost circular plate 411. At this time, the limiting post 413 on the moving block 412 corresponds to the semi-circular groove position of the lowermost circular plate 411. Thus, the compression spring pushes the limiting post 413 into the semi-circular groove through its own elastic force, fixedly connecting the lowermost circular plate 411 and the moving block 412 together. Furthermore, in the initial state, the suction cup 3 is prevented from driving the circular plate 411 to rotate.

[0063] When it is required to rotate the glass after flipping by 90 degrees, the principle is the same. The moving block 412 is made to correspond to the second circular plate 411 from bottom to top. At this time, the limiting post 413 and the semi-circular groove of the second circular plate 411 from bottom to top are 90 degrees apart. So that after the suction cup 3 drives the circular plate 411 to rotate by 90 degrees, the circular plate 411 and the moving block 412 can be locked together, and so on.

[0064] Refer to Figure 2 、 Figure 3 and Figure 6 One end of the transmission shaft 42 close to the U-shaped frame 11 is fixedly installed with a transmission bevel gear 421. Three bevel gear segments 422 arranged equidistantly along the circumferential direction of the rotation of the flipping frame 2 are slidably arranged back and forth on the vertical section at the rear of the U-shaped frame 11 through a guiding square rod 423.

[0065] Refer to Figure 6, two arc-shaped slots arranged front and back are provided on the guiding square rod 423. An arc-shaped insertion rod 424 for inserting into the arc-shaped slots is rotatably arranged inside the vertical section at the rear of the U-shaped frame 11. The arc-shaped insertion rod 424 is locked to the U-shaped frame 11 through fastening screws.

[0066] The operator moves the bevel gear segment 422 back and forth in advance according to the rotation angle of the glass after flipping. When the glass after flipping does not need to rotate, there is no need to move the bevel gear segment 422 forward. When the glass after flipping needs to rotate by 90 degrees, move one bevel gear segment 422 forward. When the glass after flipping needs to rotate half a turn, move two bevel gear segments 422 forward, and so on.

[0067] Subsequently, the operator manually rotates the arc-shaped insertion rod 424 and inserts it into the arc-shaped slots at the corresponding positions of all the guiding square rods 423 at the same time, so as to lock the guiding square rod 423 and the U-shaped frame 11 together.

[0068] It should be noted that a first bevel gear is fixedly installed at one end of the transmission shaft 42 close to the suction cup 3, and a second bevel gear meshing with the first bevel gear is fixedly installed on the outside of the suction cup 3.

[0069] When the glass after flipping needs to be rotated, the rotating flipping frame 2 drives the transmission bevel gear 421 to mesh with the bevel gear segment 422 after moving forward through the transmission shaft 42. When the transmission bevel gear 421 crosses a bevel gear segment 422 meshing with it, the transmission bevel gear 421 drives the transmission shaft 42 to rotate by 90 degrees. The transmission shaft 42 drives the suction cup 3 to rotate through the first bevel gear and the second bevel gear. The suction cup 3 drives the glass to rotate, and the glass drives the linkage plate 51 to rotate through the telescopic arm 52, and at the same time compresses the arc-shaped spring.

[0070] When the transmission bevel gear 421 crosses all the bevel gear segments 422 meshing with it, the glass rotates to the required angle, and the semi-circular groove on the circular plate 411 at the corresponding position driven by the suction cup 3 is exactly aligned with the position of the limit post 413. The compression spring pushes the limit post 413 into the semi-circular groove through its own elastic force, fixedly connecting the circular plate 411 and the moving block 412 together, preventing the suction cup 3 and the glass from rotating, and the elastic force of the arc-shaped spring is not enough to push the glass to rotate.

[0071] When the glass flips half a turn, the rack 13 drives the locking groove on it to move to the position of the locking block 15. Subsequently, the elastic force of the spiral spring drives the locking block 15 to move upward through the U-shaped frame 11, so that the T-shaped plate 16 pushes the locking block 15 to insert into the locking groove through the inclined surface on it, and compresses the pushing spring, thereby fixedly connecting the rack 13 and the U-shaped frame 11 together, and further making the rack 13 unable to drive the flipping frame 2 to rotate anymore.

[0072] And during this process, the locking block 15 drives the two protruding columns on the circular rod member 151 to move from the inside of the linear waist-shaped groove of the left ring member 153 to the inclined surface structure of the right ring member 152, and causes the protruding columns to rotate 45 degrees along the inclined surface structure of the right ring member 152. Subsequently, the telescopic section of the retracting hydraulic cylinder 14 drives the glass to move vertically downward through the turning frame 2, so that the locking block 15 moves to the lower part of the T-shaped plate 16.

[0073] At this time, the pushing spring pushes the locking block 15 to move leftward through its own elastic force. The locking block 15 drives the two protruding columns to move to the inclined surface structure of the left ring member 153 through the circular rod member 151, and causes the protruding columns to rotate 45 degrees again along the inclined surface structure of the left ring member 153, so that the two protruding columns are blocked by the inclined surface structure of the left ring member 153, preventing the locking block 15 from completely withdrawing from the inside of the locking groove, and ensuring the locking of the U-shaped frame 11 and the rack 13.

[0074] When the suction cup 3 starts to move vertically downward, the telescopic section of the retracting air cylinder 54 is retracted, so that the clamping frame 53 no longer clamps the glass, causing the telescopic arms 52 to swing downward under the action of gravity, so that the two telescopic arms 52 completely move to the lower part of the glass. At the same time, the arc spring pushes the rotated linkage plate 51 to reverse to the initial angle through its own elastic force, so that the two telescopic arms 52 are arranged left and right again, preventing the telescopic arms 52 from blocking between the glass and the transmission device. Then the suction cup 3 moves to the lower part of the conveying device and places the glass on the conveying device.

[0075] Then the telescopic section of the hydraulic cylinder 14 is extended again to drive the locking block 15 to contact the inclined surface of the T-shaped plate 16. Subsequently, the telescopic section of the hydraulic cylinder 14 is retracted. Similarly, the two protruding columns rotate 90 degrees again, causing the two protruding columns to correspond to the position of the linear waist-shaped groove. Then the pushing spring pushes the locking block 15 to move leftward through its own elastic force to withdraw from the inside of the locking groove, unlocking the U-shaped frame 11 and the rack 13.

[0076] Therefore, when the rack 13 moves downward, the spiral spring pushes the U-shaped frame 11 upward through its own elastic force so as not to move downward, causing the rack 13 to drive the turning frame 2 to reverse half a turn to the initial position, and at the same time the suction cup 3 reverses to the initial angular position, so as to facilitate the flipping of the glass again.

[0077] Refer to Figures 1 to 8 When the present invention flips the glass, it further includes the following steps: First step, the conveying device moves the glass to directly below the suction cup 3. The telescopic section of the retracting hydraulic cylinder 14 drives the suction cup 3 to move downward to abut against the upper side surface of the glass, and adsorbs the glass through the suction cup 3.

[0078] In the second step, the telescopic section of the hydraulic cylinder 14 extends to drive the glass to move vertically upward through the suction cup 3. The telescopic section of the air cylinder 54 extends to push the deflection of the clamping bracket 53, so that the clamping bracket 53 clamps and protects the glass, and the lower side of the glass is protected by the rollers 55 on the clamping bracket 53.

[0079] In the third step, the T-shaped plate 16 blocks the U-shaped bracket 11 from continuing to move upward. The rack 13 drives the glass to flip through the driven gear 12. The bevel gear section 422 drives the glass to rotate to a corresponding angle through the suction cup 3. At the same time, the arc spring is compressed, and the limit post 413 is inserted into the inside of the semi-circular groove to fixedly connect the circular plate 411 and the moving block 412 together.

[0080] In the fourth step, after the glass flips half a circle, the T-shaped plate 16 pushes the locking block 15 into the inside of the locking groove. The round rod 151 locks the position of the locking block 15. The retracted hydraulic cylinder 14 drives the glass to move vertically downward. The telescopic section of the retracted air cylinder 54, and the arc spring pushes the telescopic arm 52 to reverse and reset through its own elastic force.

[0081] In the fifth step, the telescopic section of the extended hydraulic cylinder 14 drives the locking block 15 to contact the inclined surface of the T-shaped plate 16. Subsequently, the telescopic section of the retracted hydraulic cylinder 14 is used to make the two convex columns rotate ninety degrees again. The spiral spring pushes the U-shaped bracket 11 upward through its own elastic force so as not to move downward, so that the rack 13 drives the flipping frame 2 to reverse half a circle to the initial position. At the same time, the suction cup 3 reverses to the initial angular position to facilitate flipping the glass again.

[0082] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
