Description

Technical Field

[0001] This application relates to the field of glass sheet processing technology, specifically to a fixture for fixing glass sheets in the later processing stage. Background Technology

[0002] Glass slides can be categorized into various types based on their application, such as slides, cover plates, filters, or optical lenses used in optics or laboratories, and flat glass, tempered glass, or laminated glass used in industry or construction. Common glass slide shapes include circular, square, and rectangular. During post-processing, glass slides require fixing fixtures. In existing technologies, these fixtures typically employ circular suction cup structures to adhere and fix the glass slides. In practice, the glass slide is placed on the circular suction cup structure, and manual adjustment is required to keep the glass slide and the suction cup structure centered. This method is not only cumbersome but also prone to errors, as the glass slide is easily misaligned, affecting subsequent processing. Therefore, a new fixing fixture for post-processing of glass slides is proposed. Utility Model Content

[0003] The purpose of this application is to solve the technical problem that relying on manual adjustment to keep the glass sheet and the circular suction cup structure centered is not only cumbersome to operate, but also has a large error, and the glass sheet is prone to positional displacement, which affects the subsequent processing. This application provides a glass sheet post-processing fixing fixture.

[0004] To achieve the above objectives, this application specifically adopts the following technical solution:

[0005] A fixture for post-processing glass sheets includes a frame, on which a fixed frame, a main suction cup, and a vacuum pump are mounted. The main suction cup has a main suction groove and a through groove that are connected. The vacuum pump and the through groove are connected by a pipe. Four positioning rods are slidably mounted on the fixed frame. The fixed frame is equipped with a driving component for driving the four positioning rods to slide synchronously. Two of the positioning rods are oppositely distributed and are adjusting rods. An inner rod is slidably mounted on the adjusting rod, and a return spring is provided between the inner rod and the inner rod. The adjusting rod is equipped with a locking component for locking or unlocking the inner rod.

[0006] Furthermore, the main suction cup has multiple cavities that are all connected to the through groove. A slide rod is slidably arranged in each cavity. A secondary suction cup is arranged on the slide rod. A secondary suction groove is constructed on the secondary suction cup. A channel is constructed on the slide rod that is connected to both the secondary suction groove and the cavity.

[0007] Furthermore, the frame is provided with a drive unit for driving multiple slide bars to slide synchronously.

[0008] Furthermore, the drive unit includes a bevel gear ring and a plurality of lead screws rotatably mounted on the frame. A fixed motor is mounted on the frame. Both the lead screws and the output shaft of the fixed motor are provided with bevel gears that mesh with the bevel gear ring. A drive block that threadedly engages with the lead screw is mounted on the slide rod.

[0009] Furthermore, both the main adsorption tank and the secondary adsorption tank include grooves, multiple perforations, and adsorption cavities connected in sequence. The perforations and channels are respectively connected to the two adsorption cavities. The grooves include multiple annular grooves and strip grooves. The multiple annular grooves form a concentric circle structure, and the multiple strip grooves are distributed in a ring array.

[0010] Furthermore, the fixed frame is slidably mounted on the machine frame, and the machine frame is provided with a cylinder push rod whose movable end is connected to the fixed frame.

[0011] Furthermore, the driving component includes four sprockets rotatably mounted on a fixed frame. The fixed frame is equipped with a drive motor whose output shaft is connected to one of the sprockets. A chain is wound around the four sprockets. Four drive plates are mounted on the chain. The drive plates are provided with inclined grooves. The positioning rod is provided with a protrusion that slides with the inclined groove.

[0012] Furthermore, the locking element includes a through hole on the adjusting rod, and the inner rod is provided with a locking hole communicating with the through hole. A locking pin is movably inserted into the through hole and the locking hole.

[0013] The beneficial effects of this application are as follows: When using this application, the glass sheet is placed horizontally on the main suction cup. If the glass sheet is round or square, it is driven to move by four positioning rods until the glass sheet is centered with the main suction cup, and then the glass sheet is adsorbed and fixed. If the glass sheet is rectangular, it is driven to move by two inner rods and two positioning rods until the glass sheet is centered with the main suction cup. Compared with the manual adjustment method, it is more convenient to operate, reduces errors, avoids the glass sheet from shifting position, and ensures subsequent processing, thus making it more practical.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figures 1-6 As shown in one embodiment of this application, a glass sheet post-processing fixture includes a frame 1, a fixing frame 2, a main suction cup 3, and a vacuum pump 4. The main suction cup 3 and the vacuum pump 4 are both fixed on the frame 1. The main suction cup 3 has a main suction groove 5 and a through groove 6 that are connected. The main suction groove 5 and the through groove 6 are distributed vertically. The vacuum pump 4 and the through groove 6 are connected by a pipe. Four positioning rods 7 are slidably arranged on the fixing frame 2. The four positioning rods 7 are arranged in a circular array around the main suction cup 3. The positioning rods 7 slide in the horizontal direction. The fixing frame 2 is provided with a driving component for driving the four positioning rods 7 to slide synchronously. Synchronous sliding here means that the four positioning rods 7 move closer to or away from the main suction cup 3 synchronously. Two of the positioning rods 7 are oppositely distributed as adjusting rods. An inner rod 8 is slidably arranged on the adjusting rod and a return spring 9 is arranged between the two. The inner rod 8 slides in the horizontal direction. The return spring 9 is in the horizontal direction and its two ends are fixedly connected to the adjusting rod and the inner rod 8, respectively. The adjusting rod is provided with a locking component for locking or unlocking the inner rod 8.

[0023] In the initial state, all four positioning rods 7 are far from the main suction cup 3, the inner rod 8 is in the initial position, and the return spring 9 is in a stretched state. The inner rod 8 is locked by the locking device. When the glass sheet is processed later, the glass sheet is placed horizontally on the main suction cup 3. If the glass sheet is round or square, the driving device drives the four positioning rods 7 to slide synchronously until they are close to the main suction cup 3, until all four positioning rods 7 are in contact with the side of the glass sheet. The four positioning rods 7 drive the glass sheet to move together until the glass sheet is centered with the main suction cup 3. Then, the driving device drives the four positioning rods 7 to slide synchronously away from the main suction cup 3, so that the vacuum pump 4 works and the air in the main adsorption tank 5 and the through tank 6 is extracted, so that a negative pressure environment is formed in the main adsorption tank 5 and the through tank 6, thereby adsorbing and fixing the glass sheet. If the glass sheet is rectangular, the locking device unlocks the inner rod 8 and resets it. Spring 9 returns to its natural state, inner rod 8 slides to its limit position, and then the driving component drives the four positioning rods 7 to slide synchronously close to the main suction cup 3. During this process, the two inner rods 8 first contact the side of the glass sheet, forcing the inner rods 8 to slide to the initial position, and the return spring 9 is stretched. Then, the two oppositely distributed positioning rods 7 contact the side of the glass sheet, and the glass sheet is driven to move together by the two inner rods 8 and the two positioning rods 7 until the glass sheet is centered with the main suction cup 3. Then, the driving component drives the four positioning rods 7 to slide synchronously away from the main suction cup 3, so that the inner rod 8 slides to the initial position, the return spring 9 is stretched, and the inner rod 8 is locked by the locking component, so that the vacuum pump 4 works to extract the air in the main adsorption tank 5 and the through tank 6, so that a negative pressure environment is formed in the main adsorption tank 5 and the through tank 6, thereby adsorbing and fixing the glass sheet.

[0024] In summary, when using this application, the glass sheet is placed horizontally on the main suction cup 3. If the glass sheet is round or square, the glass sheet is driven to move together by the four positioning rods 7 until the glass sheet is centered with the main suction cup 3, and then the glass sheet is adsorbed and fixed. If the glass sheet is rectangular, the glass sheet is driven to move together by the two inner rods 8 and the two positioning rods 7 until the glass sheet is centered with the main suction cup 3. Compared with the manual adjustment method, the operation is convenient, while reducing errors, avoiding the glass sheet from shifting position, and ensuring subsequent processing, thus making it more practical.

[0025] like Figures 1-4 As shown, in some embodiments, the main suction cup 3 is constructed with a plurality of cavities 10 that are all connected to the through groove 6. The plurality of cavities 10 are arranged in a circular array with the through groove 6 as the center. A slide rod 11 is slidably disposed in the cavity 10. The slide rod 11 slides in the horizontal direction. A secondary suction cup 12 is disposed on the slide rod 11. The secondary suction cup 12 is fixed on the slide rod 11. The top surface of the secondary suction cup 12 is located on the same horizontal plane as the top surface of the main suction cup 3. A secondary adsorption groove 13 is constructed on the secondary suction cup 12. A channel 14 is constructed on the slide rod 11 that is connected to both the secondary adsorption groove 13 and the cavity 10.

[0026] Referring to the above, in the initial state, the slide bar 11 is in the initial position, and the auxiliary suction cup 12 is in contact with the main suction cup 3. When the glass sheet is placed horizontally on the main suction cup 3, the glass sheet is in contact with multiple auxiliary suction cups 12. When the vacuum pump 4 works, the air in the auxiliary adsorption tank 13, channel 14 and cavity 10 is extracted, so that a negative pressure environment is formed in the auxiliary adsorption tank 13, channel 14 and cavity 10, which adsorbs and fixes the glass sheet, further improving the fixing effect of the glass sheet and improving the stability of use. When the glass sheet is large, the slide bar 11 can be driven to slide to the limit position, which will drive the auxiliary suction cup 12 to move away from the main suction cup 3, and then the glass sheet can be placed horizontally on the main suction cup 3 and multiple auxiliary suction cups 12, thereby improving the support stability of the glass sheet and further improving the stability of use.

[0027] like Figure 4 As shown, in some embodiments, the frame 1 is provided with a drive unit for driving multiple slide bars 11 to slide synchronously. Here, synchronous sliding means that multiple slide bars 11 move closer to or further away from the slot 6 at the same time.

[0028] Referring to the above, during use, the drive unit drives multiple sliders 11 to slide synchronously, so that multiple auxiliary suction cups 12 move away from or closer to the main suction cup 3 simultaneously, making operation more convenient.

[0029] like Figure 4 As shown, in some embodiments, the drive unit includes a bevel ring 15 and a plurality of lead screws 16 rotatably mounted on the frame 1. The bevel ring 15 and the lead screws 16 are both horizontal. The bevel ring 15 is coaxially distributed with the main suction cup 3. The plurality of lead screws 16 are arranged in a ring array around the main suction cup 3. A fixed motor 17 is mounted on the frame 1. The fixed motor 17 is fixed on the frame 1. The output shafts of the lead screws 16 and the fixed motor 17 are both provided with bevel gears 18 that mesh with the bevel ring 15. The bevel gears 18 are vertical. A drive block 19 is provided on the slide rod 11 that is threadedly engaged with the lead screw 16. The drive block 19 is fixed on the slide rod 11.

[0030] Referring to the above, when in use, the fixed motor 17 is turned on, and the output shaft rotates forward, driving the bevel gear 18 on its output shaft to rotate. The bevel gear ring 15 will rotate due to meshing, and the other bevel gears 18 will rotate synchronously due to meshing, so as to realize the synchronous rotation of multiple lead screws 16. Multiple drive blocks 19 slide synchronously due to the thread action, thereby driving multiple slide rods 11 to slide synchronously away from the through slot 6, and multiple auxiliary suction cups 12 to move synchronously away from the main suction cup 3. Conversely, when the output shaft of the fixed motor 17 is reversed, it drives multiple slide rods 11 to slide synchronously closer to the through slot 6, and multiple auxiliary suction cups 12 to move synchronously closer to the main suction cup 3.

[0031] like Figures 3-4As shown, in some embodiments, the main adsorption tank 5 and the secondary adsorption tank 13 each include grooves, multiple perforations and adsorption cavities connected in sequence. The grooves, multiple perforations and adsorption cavities are distributed from top to bottom. The multiple perforations are distributed in a ring array. The perforation 6 and the channel 14 are respectively connected to the two adsorption cavities. The grooves include multiple annular grooves and strip grooves. The multiple annular grooves form a concentric circle structure. The multiple strip grooves are distributed in a ring array.

[0032] Referring to the above, during use, the air in the groove, multiple perforations, and adsorption chamber is extracted in sequence, and a negative pressure environment is formed in both the main adsorption groove 5 and the secondary adsorption groove 13, thereby adsorbing and fixing the glass sheet. The groove is formed by multiple annular grooves and multiple strip grooves, which can increase the adsorption and fixing area of ​​the glass sheet, thereby improving the adsorption and fixing effect of the glass sheet.

[0033] like Figure 2 As shown, in some embodiments, the fixed frame 2 is slidably mounted on the frame 1, the fixed frame 2 slides in the vertical direction, and the frame 1 is provided with a cylinder push rod 20 whose movable end is connected to the fixed frame 2. The cylinder push rod 20 is in the vertical direction and fixed on the frame 1.

[0034] Referring to the above, in the initial state, the movable end of the cylinder push rod 20 retracts, and the fixed frame 2 is in the initial position and its height is lower than that of the main suction cup 3, so that the glass sheet can be placed horizontally on the main suction cup 3 and multiple auxiliary suction cups 12. Then, the movable end of the cylinder push rod 20 extends, driving the fixed frame 2 to slide upward to the limit position. The top surface of the fixed frame 2 and the top surface of the main suction cup 3 are on the same horizontal plane, and subsequent operations can be carried out. Then, the movable end of the cylinder push rod 20 retracts, and the fixed frame 2 slides downward to the initial position, without affecting the subsequent processing of the glass sheet.

[0035] like Figures 5-6 As shown, in some embodiments, the driving component includes four sprockets 21 rotatably mounted on the fixed frame 2. The four sprockets 21 are arranged in a rectangular array and their axes are all vertical. The fixed frame 2 is provided with a drive motor 22 whose output shaft is connected to one of the sprockets 21. The drive motor 22 is fixed on the fixed frame 2. A chain 23 is wound around the four sprockets 21. Four drive plates 24 are provided on the chain 23. The drive plates 24 are horizontal and fixed on the chain 23. The drive plates 24 are provided with inclined grooves 25. The positioning rod 7 is provided with protrusions 26 that slide with the inclined grooves 25. The protrusions 26 are vertical and fixed on the positioning rod 7. The inclined grooves 25 have relatively distributed initial points and limit points.

[0036] Referring to the above, in the initial state, all four positioning rods 7 are in their initial positions, and the protrusion 26 is located at the initial point of the inclined groove 25. During use, the drive motor 22 is activated, and the output shaft rotates forward, driving one of the sprockets 21 to rotate. This sprocket 21 drives the chain 23 and the other three sprockets 21 to rotate together. The chain 23 drives the four drive plates 24 to move synchronously. During this process, the protrusion 26 slides from the initial point to a point close to its limit, thereby driving the positioning rod 7 to slide closer to the main suction cup 3. Conversely, when the output shaft of the drive motor 22 rotates in reverse, the protrusion 26 slides from the limit point back to the initial point, thereby driving the positioning rod 7 to slide away from the main suction cup 3, so as to drive the four positioning rods 7 to slide synchronously.

[0037] like Figures 5-6 As shown, in some embodiments, the locking member includes a through hole 27 opened on the adjusting rod, and a locking hole 28 communicating with the through hole 27 is provided on the inner rod 8. Both the through hole 27 and the locking hole 28 are vertical, and a locking pin 29 is movably inserted into the through hole 27 and the locking hole 28.

[0038] Referring to the above, in the initial state, the through hole 27 and the locking hole 28 are connected, and the locking pin 29 is inserted into the through hole 27 and the locking hole 28. Due to the obstruction of the locking pin 29, the inner rod 8 cannot slide, thus locking the inner rod 8. When in use, pull the locking pin 29 upward, and the locking pin 29 will exit the locking hole 28. The inner rod 8 will no longer be obstructed by the locking pin 29 and can slide. The through hole 27 and the locking hole 28 are staggered, thus unlocking the inner rod 8.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
