The correction mechanism 50 is used to correct the position of the lower cavity body 22. The correction mechanism 50 includes a point spectrum component 51 and a camera component 52. The correction mechanism 50 and the lower driving member 21 are respectively connected to the controller. In some specific embodiments, the controller connects various mechanisms in the dispensing glue bonding device.

[0054] The above-mentioned glue dispensing and bonding device places the upper glass sheet and the lower glass sheet in the lower cavity body 22, and the upper glass sheet and the lower glass sheet are placed separately without overlapping each other. The lower driving member 21 is controlled by the correction mechanism 50 to drive the lower cavity body 22 so that the upper glass sheet and the material taking fixture 421 are aligned and corrected, and the upper cavity driving member drives the upper cavity body 42 to move, and the upper glass sheet is taken out by the material taking fixture 421; the correction mechanism 50 corrects the lower glass sheet until it reaches the accuracy required by the glue dispensing mechanism 30 for glue dispensing on its upper surface, and the lower cavity body 22 moves to the glue dispensing mechanism 30, and the glue dispensing driving member drives the glue dispensing needle 31 to dispense glue to the lower glass sheet, thereby realizing high-precision glue dispensing.

[0055] See also Figure 2 , Figure 2 A schematic structural diagram of the lower chamber mechanism 20 of some embodiments of the present application is shown.

[0056] The lower cavity mechanism 20 includes a lower driving member 21 and a lower cavity body 22. The lower driving member 21 drives the lower cavity body 22 to move. The lower cavity body 22 is used to place the lower glass sheet and the upper glass sheet. The upper glass sheet and the lower glass sheet are placed separately and do not overlap each other. The lower cavity body 22 is arranged at the upper end of the lower driving member 21. The lower cavity body 22 is a three-dimensional hollow structure with an upper opening. Preferably, the lower cavity body 22 is a rectangular structure. Preferably, the bottom surface of the lower cavity body 22 is parallel to the ground where the frame 10 is located, so that the lower glass sheet and the upper glass sheet can maintain a relatively stable position after being placed.

[0057] In some specific embodiments, a lower cavity fixture 221 is provided in the lower cavity body 22 for placing the lower glass sheet. The upper surface of the lower cavity fixture 221 fits the lower surface of the lower glass sheet, and the lower glass sheet can be stably placed. In some specific embodiments, the lower cavity fixture 221 is provided with a fixing element, which can fix the lower glass sheet on the lower cavity fixture 221 to prevent the lower glass sheet from being displaced during the movement of the lower cavity body 22, thereby affecting the accuracy of the correction. Preferably, the fixing element is a vacuum adsorption component, which can fix the glass sheet while preventing the glass sheet from moving during the fixing process.

[0058] In some specific embodiments, the upper glass sheet can be placed inside the lower cavity body 22 or outside the lower cavity body 22. Preferably, a loading jig 222 is provided outside the lower cavity body 22 for placing the upper glass sheet, and the upper surface of the loading jig 222 fits the lower surface of the upper glass sheet, so that the upper glass sheet can be stably placed. Furthermore, the loading jig 222 is provided with a fixing element, which can fix the upper glass sheet on the loading jig 222 to prevent it from being displaced during the movement of the lower cavity body 22, thereby affecting the accuracy of the calibration.

[0059] In some specific embodiments, the loading fixture 222 is connected to a lifting assembly. Specifically, the lifting assembly is a cylinder, which can make the loading fixture 222 rise and fall along the vertical direction of the Z axis, so as to facilitate the subsequent operation of taking up the upper glass sheet.

[0060] In some specific embodiments, the lower cavity mechanism 20 includes a correction piece, which can adjust the position of the lower cavity fixture 221. Specifically, the correction piece can move in six degrees of freedom in space to correct the spatial angle position. Specifically, the correction piece uses a six-degree-of-freedom correction platform 23.

[0061] See also Figure 2 and Fig.11 , Fig.11 A schematic diagram showing the dispensing mechanism of some embodiments of the present application dispensing glue on the lower glass sheet is shown. For ease of viewing, Fig.11 The lower cavity body 22 is hidden. In some specific embodiments, the spatial six-degree-of-freedom correction platform 23 is disposed between the lower driving member 21 and the lower cavity body 22, and is connected to the lower cavity fixture 221. Under the control of the controller, the spatial position of the lower cavity fixture 221 in the lower cavity body 22 can be accurately adjusted, thereby adjusting the spatial position of the lower glass sheet on the lower cavity fixture 221, so that it can be accurately corrected.

[0062] Combined with reference Figure 1 and Figure 2In some specific embodiments, the lower driving member 21 may be a mechanical arm or a sliding member.

[0063] In some specific embodiments, the glue dispensing and bonding device also includes a feeding mechanism to store a plurality of upper glass sheets and lower glass sheets and transport them to the lower chamber mechanism 20, where they are loaded by a robotic arm or manually and the upper glass sheets and lower glass sheets are placed on the loading jig 222 and the lower chamber jig 221, respectively.

[0064] See also Figure 3 , Figure 3 A schematic structural diagram of a dispensing mechanism according to some embodiments of the present application is shown.

[0065] The glue dispensing mechanism 30 includes a glue dispensing needle 31 and a glue dispensing driving member. The glue dispensing driving member drives the glue dispensing needle 31 to dispense glue to the lower glass sheet. The glue dispensing needle 31 is preset with a fixed glue dispensing path. Since the present application calibrates the position of the lower glass sheet, the glue dispensing position of the lower glass sheet is located at the same position each time. The so-called glue dispensing position refers to the position of the lower glass sheet located at the glue dispensing mechanism 30 after calibration. The glue dispensing path of the glue dispensing needle 31 is fixed. Therefore, the glue dispensing needle 31 only needs to preset a fixed path for dispensing glue with a spatial angle on the curved surface, without the need to adjust it each time, which significantly improves the glue dispensing efficiency.

[0066] In some specific embodiments, the dispensing drive is configured as a six-axis dispensing robot arm 32, which can flexibly drive the dispensing needle 31 to move and dispense glue on a flat surface or a curved surface.

[0067] In some specific embodiments, the glue dispensing mechanism 30 includes a first spot curing device 33, and the glue dispensing needle 31 forms a glue dispensing layer after dispensing glue on the lower glass sheet. The glue dispensing layer includes a first area and a second area, and the first spot curing device 33 cures the first area. The glue dispensing needle 31 applies glue on the upper surface of the lower glass sheet according to a preset path, and the glue is not cured to form a glue dispensing layer. Preferably, the first area is the part close to the edge of the glue dispensing layer, and the first spot curing device 33 is used to cure the part of the glue dispensing layer close to the edge to form a dam-like dam-like solidified glue, which is very thin, but can protrude from the upper surface of the lower glass sheet to prevent the phenomenon of a large amount of glue overflowing when the upper and lower glass sheets are attached together. In some specific embodiments, the first spot curing device 33 is configured as a UV point light source curing lamp, and the glue used by the glue dispensing needle 31 is a water-based glue or other glue that is cured by UV. UV curing is a prior art and will not be described in detail here.

[0068] See also Figure 2, further, a second spot curing device 2211 is provided in the sealed space, and the second spot curing device 2211 cures the second area. Specifically, the second spot curing device 2211 is provided on the lower cavity fixture 221. In some specific embodiments, the second area is a part of the glue layer squeezed between the upper glass sheet and the lower glass sheet after the two are bonded. Specifically, the second spot curing device 2211 can be provided to cure perpendicularly to the upper glass sheet and the lower glass sheet, or it can be provided as Figure 2 As shown, curing is performed from the sides of the upper glass sheet and the lower glass sheet bonded together. The purpose of curing by the second point curing device 2211 is to cure part of the glue, i.e., the second area, so that the upper glass sheet and the lower glass sheet are adhered and fixed together, to prevent the upper glass sheet from being displaced when the material picking fixture 421 leaves the upper glass sheet, or the lower cavity body 22 moves with the upper glass sheet and the lower glass sheet bonded together, causing relative displacement between the upper glass sheet and the lower glass sheet, thereby affecting the bonding accuracy.

[0069] In some specific embodiments, the glue dispensing laminating device further includes a glue dispensing wiping mechanism, which is disposed near the glue dispensing mechanism 30 and is used to wipe the glue dispensing needle 31 .

Specifically, a connecting component, such as a right-angle plate, is further provided between the upper chamber body 42 and the upper driving member 41 to fix the upper chamber body to the upper driving member 41. There are many commonly used means, which will not be repeated here.

[0072] In some specific embodiments, the upper driving member 41 may be a mechanical arm or a sliding member, etc. Preferably, the upper driving member 41 is configured as a second motor and a second slider, and the frame 10 is correspondingly provided with a second vertically arranged slide rail 12. Driven by the second motor, the second slider can drive the upper cavity body 42 to move up and down in a vertical direction on the second slide rail 12, so that the upper cavity body 42 moves closer to or away from the lower cavity body 22 below the upper cavity body 42.

[0073] Specifically, the upper cavity body 42 is a three-dimensional hollow structure with an opening toward the bottom. Preferably, the upper cavity body 42 is a rectangular structure. Preferably, the top surface of the upper cavity body 42 is parallel to the ground where the rack 10 is located.

[0074] In some specific embodiments, the material picking jig 421 is provided with a fixing element, which can fix the upper glass sheet on the material picking jig 421 and take it away. Specifically, the fixing element can be a vacuum suction piece, which can fix the glass sheet while preventing the glass sheet from moving. In some specific embodiments, the shape of the material picking jig 421 matches the shape of the upper glass sheet. When the material picking jig 421 picks the upper glass sheet, the lower surface of the material picking jig 421 fits the upper surface of the upper glass sheet. Through the adsorption effect of the vacuum suction piece, the upper glass sheet is stably fixed on the material picking jig 421, and the material picking and movement operations are performed.

[0075] In some specific embodiments, the upper driving member 41 can drive the upper cavity body 42 to move to cover the lower cavity body 22 to form a sealed space, and the sealed space is connected to a vacuum pumping mechanism, which can pump the sealed space into a vacuum state and release the vacuum state. In some specific embodiments, the vacuum pumping mechanism is connected to the lower cavity body 22 and communicates with the internal space of the lower cavity body 22.

[0076] Specifically, when the upper cavity body 42 and the lower cavity body 22 are covered together, the calibrated upper glass sheet and the lower glass sheet are also attached together, and the glue layer is squeezed between the two. Further, after vacuuming, the air between the upper glass sheet and the lower glass sheet is squeezed out by air pressure, so that the upper glass sheet, the glue layer and the lower glass sheet are tightly attached without bubbles.

[0077] In some specific embodiments, the lower opening of the upper cavity body 42 and the upper opening of the lower cavity body 22 are both provided with sealing strips and other sealing members. When the upper cavity body 42 and the lower cavity body 22 are covered, the lower opening and the upper opening are tightly covered together and sealed, so that the internal space of the upper cavity body 42 is connected with the internal space of the lower cavity body 22 to form a sealed space.

[0078] Continue reading Figure 1 The correction mechanism 50 is used to correct the position of the lower cavity body 22. The correction mechanism 50 includes a point spectrum component 51 and a camera component 52. The correction mechanism 50 and the lower driving member 21 are respectively connected to the controller.

For ease of viewing, Fig.10 The upper cavity body 42 is hidden, and the point spectrum component 51 measures the height values ​​of the corresponding points on the lower glass sheet and the upper glass sheet respectively. The controller calculates the difference and controls the spatial six-degree-of-freedom correction platform 23 to perform spatial angle position correction on the lower cavity fixture 221. The measurement and correction process is repeated many times until the required accuracy value is reached. The controller records the coordinate value of the spatial six-degree-of-freedom correction platform 23 at this time as the fitting coordinate.

[0093] S5. Correct the position of the lower glass sheet until the lower glass sheet reaches a spatial angle that matches the fixed path preset by the dispensing mechanism 30.

[0097] S8, the vacuum mechanism releases the vacuum state, the upper chamber mechanism 40 leaves, and the lower chamber body 22 moves to the curing piece to perform overall curing on the upper and lower glass sheets bonded together, and the processing is completed.

[0098] In some specific implementations, step S6 further includes curing the first area using the first spot curing device 33 to form a dam. Specifically, the first area is a portion close to the edge of the spot glue layer, and the first spot curing device 33 is used to cure the portion of the spot glue layer close to the edge to form a dam-like dam. The cured glue has a very thin thickness, but can protrude from the upper surface of the lower glass sheet to prevent a large amount of glue from overflowing when the upper and lower glass sheets are attached together.

[0099] See also Fig.13 In some specific embodiments, step S7 further includes that after the upper glass sheet is tightly attached to the lower glass sheet, the second spot curing device 2211 cures the second area. Specifically, the second area is a part of the glue layer squeezed between the upper glass sheet and the lower glass sheet after they are attached. Specifically, the second spot curing device 2211 can cure perpendicularly to the upper glass sheet and the lower glass sheet, or can cure from the sides of the upper glass sheet and the lower glass sheet that are attached together, with the purpose of curing part of the glue so that the upper glass sheet and the lower glass sheet are adhered and fixed together, fixing the upper glass sheet, and preventing the upper glass sheet from being displaced when the material removal jig 421 leaves the upper glass sheet, or the attached glass sheets from being offset during the movement of the lower cavity body 22 to the curing part.

The lower cavity body 22 moves to the corresponding position of the glue dispensing mechanism 30, and the glue dispensing needle 31 performs glue dispensing on the upper surface of the lower glass sheet under the drive of the six-axis glue dispensing robot arm 32. After the glue dispensing is completed, a glue dispensing layer is formed on the upper surface of the lower glass sheet, and the first spot curing device 33 cures the surrounding dam glue to prevent glue overflow during subsequent material bonding. The lower cavity body 22 moves to the position corresponding to the upper cavity body 42 under the drive of the lower driving member 21, and the controller controls the spatial six-degree-of-freedom correction platform 23 to drive the lower cavity fixture 221 to move to the previous At the recorded fitting coordinates, the positions of the lower chamber jig 221 and the material picking jig 421 correspond more accurately, and the upper chamber body 42 covers the lower chamber body 22 to form a sealed space and evacuate it, so that the upper glass sheet and the lower glass sheet are tightly fitted together with the glue layer sandwiched therebetween, and the second spot curing device 2211 performs local glue curing on the glue layer sandwiched between the upper and lower glass sheets that are bonded together to prevent the upper glass sheet from shifting during the process of the material picking jig 421 leaving and the movement of the lower chamber mechanism 20. Then the vacuum mechanism releases the vacuum state, and the upper chamber body 42 leaves the lower chamber body 22, and the lower chamber body 22 carries the upper and lower glass sheets that are bonded together to the curing part for comprehensive curing of the glue layer.

[0101] The above-mentioned curved surface gluing and bonding device can enable the lower glass sheet on the lower cavity fixture 221 to maintain the same angular position state at the same waiting position for gluing during each processing process, and the gluing mechanism 30 only needs to follow a fixed gluing path to improve the gluing efficiency; it can also make the bonding position of the upper glass sheet and the lower glass sheet more precise under the joint action of the spot spectrum component 51 and the camera component 52, so that the two surfaces fit together, and it can be applied to flat and curved glass to improve the bonding accuracy.
