Description

Technical Field

[0001] This utility model relates to the field of laminated glass production technology, and in particular to a laminating tooling for laminated glass. Background Technology

[0002] Laminated glass is a composite glass product made by sandwiching one or more layers of organic polymer interlayer between two or more pieces of glass. After high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure processes, the glass and interlayer are permanently bonded together.

[0003] Chinese utility model patent CN215704871U discloses a laminar glass bonding fixture, including an upper bonding fixture and a lower bonding fixture. The upper surface of the lower bonding fixture has a cavity for placing functional glass. At least two cooperating positioning pins and positioning holes are provided on the edges of both the upper and lower bonding fixtures. The upper bonding fixture has a bonding window for applying adhesive at the corresponding position of the cavity. This laminar glass bonding fixture improves positioning accuracy, increases product yield and production efficiency, and reduces production costs through the cooperation of the upper and lower bonding fixtures.

[0004] In the process of using the laminated glass bonding fixture disclosed in the above-mentioned utility model patent, glue is applied to the glass in the cavity of the lower fixture from the bonding window. Then, another piece of glass is placed on the glass in the cavity of the lower fixture for bonding. Since air bubbles will form in the glue during the bonding process of the two pieces of glass, it is necessary to squeeze out the air bubbles between the two pieces of glass and clamp them after bonding. Therefore, after bonding the glass with the above-mentioned laminated glass bonding fixture, it is still necessary to use other tools to squeeze out the air bubbles and clamp the glass, which makes the operation steps cumbersome. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a laminating glass tooling that solves the problem of cumbersome operation steps in the existing technology of using fixtures to laminate glass.

[0006] According to an embodiment of this utility model, a laminated glass bonding fixture includes a base and a cover plate that cooperate with each other. The base has a cavity, and the cover plate has an opening that communicates with the cavity. The base also has a rotatable rotating frame located on the side of the cover plate away from the base. The rotating frame has at least one clamping component, which includes a clamping seat, a lifting plate, and a clamping knob. The clamping seat has a vertical clamping screw, and the lifting plate has a through hole for the clamping screw to pass through. The clamping knob cooperates with the clamping screw and abuts against the side of the lifting plate away from the cover plate. The lifting plate also has a vertical clamping rod, and the side of the clamping rod away from the lifting plate is covered with a flexible gasket. The rotating frame has a slot for the clamping rod to pass through, and the end of the clamping rod with the flexible gasket passes through the slot and extends into the opening.

[0007] Furthermore, the base is provided with a plurality of vertical positioning pins spaced apart, and the positioning pins are respectively located near the edge of the base, and the cover plate is provided with positioning holes that correspond to the positioning pins one by one.

[0008] Furthermore, the base is provided with a plurality of vent holes at intervals, and the vent holes are respectively connected to the cavity and penetrate the base.

[0009] Furthermore, the base is provided with a plurality of grooves at intervals, the grooves being respectively located near the edge of the cavity and communicating with the cavity.

[0010] Furthermore, the cover plate is provided with two vertical plates spaced apart, and the two vertical plates are respectively located near two opposite sides of the cover plate.

[0011] Furthermore, the base has vertical mounting rods and first locking screws at opposite ends, and the rotating frame has mounting holes that cooperate with the mounting rods and receiving grooves that accommodate the first locking screws at opposite ends. The first locking screw has a locking knob that cooperates with the first locking screw, and the locking knob abuts against the rotating frame and presses the rotating frame onto the base.

[0012] Furthermore, the clamping assembly also includes a spring sleeved on the clamping screw, the spring abutting against the end of the lifting plate away from the clamping knob and driving the lifting plate to move away from the cover plate.

[0013] Furthermore, the clamping seat is also provided with a vertical guide rod, the guide rod is spaced apart from the clamping screw, and the lifting plate is provided with a guide hole that cooperates with the guide rod.

[0014] Furthermore, the rotating frame is also provided with a sliding groove, the length direction of which is consistent with the length direction of the slot and communicates with the slot, and the pressing seat is movably disposed in the sliding groove.

[0015] Furthermore, the clamping seat is also provided with a vertical second locking screw and a locking nut that cooperates with the second locking screw. The second locking screw passes through the slide groove and the slot, and the locking nut abuts against the side of the rotating frame away from the clamping seat.

[0016] Compared with existing technologies, this utility model has the following advantages: By using a base with a cavity to accommodate the glass to be bonded and to limit its position, and after the glass is placed in the cavity, the cover plate is installed on the base. At this point, adhesive can be applied to the glass through the opening, and another piece of glass can be bonded to it. After the two pieces of glass are bonded, rotating the rotating frame moves the clamping assembly above the cover plate. Then, rotating the clamping knob moves it axially along the clamping screw and pushes the lifting plate towards the cover plate, causing the clamping rod to pass through the slot and extend into the opening to engage with the mold. After the glass is bonded together inside the cavity, the flexible gasket presses the glass firmly onto the base. At this point, the pressure generated by the flexible gasket on the glass can squeeze out air bubbles in the adhesive and clamp the glass between the base and the flexible gasket. This facilitates subsequent UV irradiation treatment of the bonded glass to cure the adhesive. This solves the technical problem of cumbersome operation steps when using existing jigs to bond glass. It has the technical effect of making it easier to squeeze out air bubbles in the bonded glass and clamp and fix it, simplifying the production steps and improving the production efficiency of laminated glass products.

Detailed Implementation

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a laminated glass bonding fixture, which is used to assist in the bonding of glass during the production of angled glass, squeeze out air bubbles in the adhesive of the bonding glass, and clamp the bonded glass to facilitate further processing.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3The laminated glass bonding fixture includes a base 100 and a cover plate 200. The base 100 has a cavity 101 for accommodating the glass to be bonded. The cover plate 200 has a window 201 that communicates with the cavity 101. After the glass is placed into the cavity 101, adhesive can be applied at the window 201 and the other piece of glass can be bonded to it. The base 100 also has a rotatable rotating frame 300 located on the side of the cover plate 200 away from the base 100. At least one clamping assembly 400 is provided on the cover plate 200. By rotating the rotating frame 300, the clamping assembly 400 can be moved above or away from the cover plate 200. The clamping assembly 400 includes a clamping seat 401, a lifting plate 402, and a clamping knob 403. The clamping seat 401 is provided with a vertical clamping screw 404, and the lifting plate 402 is provided with a through hole 405 for the clamping screw 404 to pass through. The clamping knob 403 cooperates with the clamping screw 404 and is located away from the lifting plate 402. One side of the cover plate 200 abuts against the cover plate 200. When the clamping knob 403 is rotated, the clamping knob 403 can move along the axial direction of the clamping screw 404 and push the lifting plate 402 closer to the cover plate 200. The lifting plate 402 is also provided with a vertical clamping rod 406. The side of the clamping rod 406 away from the lifting plate 402 is covered with a flexible gasket 407. The rotating frame 300 is provided with a slot 301 for the clamping rod 406 to pass through, and the end of the clamping rod 406 with the flexible gasket 407 passes through the slot 301. 1. The lifting plate 402 extends into the opening 201. When the lifting plate 402 approaches the cover plate 200 under the push of the pressing knob 403, the pressing rod 406 moves to the position where the flexible pad 407 contacts the glass in the cavity 101. As the lifting plate 402 continues to descend, the pressure generated by the flexible pad 407 on the glass can squeeze out the air bubbles in the glue. After the pressing knob 403 stops rotating, the position of the pressing rod 406 can be locked to clamp the glass between the base 100 and the flexible pad 407.

[0025] Specifically, the operation steps for bonding laminated glass using the laminar glass bonding fixture provided in this embodiment are as follows: First, place one piece of glass into the cavity 101 to position the glass. Then, install the cover plate 200 onto the base 100. At this time, apply glue to the glass from the opening 201 and place another piece of glass in so that the two pieces of glass are bonded together under the action of the glue. After the two pieces of glass are bonded, rotate the rotating frame 300 to move the pressing assembly 400 above the cover plate 200. Then, rotate the pressing knob 403 to push the lifting plate 402 towards the cover plate 200, so that the pressing rod 406 passes through the slot 301 and extends into the opening 201 until the flexible pad 407 closes the cavity. The laminated glass, after being bonded within cavity 101, is pressed firmly onto the base 100. The pressure exerted on the glass by the flexible gasket 407 squeezes out air bubbles in the adhesive. Stopping the rotation of the locking knob 107 locks the position of the clamping rod 406, clamping the glass between the base 100 and the flexible gasket 407. This facilitates subsequent UV irradiation treatment of the bonded glass to cure the adhesive. After bonding, the locking knob 107 is rotated in the opposite direction to release the lock on the clamping rod 406. Then, the rotating frame 300 is rotated to move the clamping assembly 400 away from the cover plate 200, removing the cover plate 200 from the base 100. At this point, the laminated glass can be removed from the cavity 101. The laminated glass bonding fixture provided in this embodiment can easily squeeze out air bubbles from the bonded glass and clamp and fix the glass, simplifying the production steps of laminated glass and improving the production efficiency of laminated glass products.

[0026] like Figure 1 and Figure 3 As shown, the base 100 is provided with a plurality of vertical positioning pins 102 spaced apart, and the positioning pins 102 are respectively located near the edge of the base 100. The cover plate 200 is provided with positioning holes 202 that correspond one-to-one with the positioning pins 102. The base 100 and the cover plate 200 are positioned by the cooperation of the positioning pins 102 and the positioning holes 202, so as to facilitate the installation of the cover plate 200 onto the base 100 and ensure that the opening 201 is aligned with the cavity 101 after the cover plate 200 is installed onto the base 100.

[0027] Please refer to Figure 3The base 100 is provided with a plurality of vent holes 103 at intervals. The vent holes 103 are respectively connected to the cavity 101 and penetrate the base 100. The vent holes 103 allow the gas in the air bubbles in the adhesive to be discharged to the external environment when the air bubbles in the adhesive are squeezed out, so as to ensure that the air bubbles in the adhesive can be smoothly eliminated when the glass in the cavity 101 is subjected to the pressure generated by the flexible gasket 407, thereby improving the reliability of the laminated glass bonding fixture.

[0028] In detail, the base 100 is provided with a plurality of grooves 104 at intervals. The grooves 104 are respectively located near the edge of the cavity 101 and communicate with the cavity 101. The grooves 104 are used to expose the glass portion inside the cavity 101 so that the glass can be removed from the cavity 101 after the glass is bonded.

[0029] like Figure 1 and Figure 3 As shown, two vertical plates 203 are spaced apart on the cover plate 200, and the two vertical plates 203 are respectively arranged near two opposite sides of the cover plate 200. The vertical plates 203 arranged on the cover plate 200 facilitate the removal of the cover plate 200, thereby making it easy to place the cover plate 200 on the base 100 or remove the cover plate 200 from the base 100.

[0030] Please combine Figure 1 , Figure 2 and Figure 3The base 100 has vertical mounting rods 105 and first locking screws 106 at opposite ends. The rotating frame 300 has mounting holes that cooperate with the mounting rods 105 and receiving grooves 302 that accommodate the first locking screws 106 at opposite ends. The first locking screws 106 have locking knobs 107 that cooperate with the first locking screws 106 and the locking knobs 107 abut against the rotating frame 300 and press the rotating frame 300 onto the base 100. The rotating frame 300 and the base 100 are rotatably connected through the mating of the mounting holes. When the rotating frame 300 rotates until the first locking screw 106 enters the receiving groove 302, the clamping assembly 400 is moved above the cover plate 200. At this time, rotating the locking knob 107 to abut against the rotating frame 300 locks the position of the rotating frame 300, preventing the rotating frame 300 from moving unexpectedly after the clamping assembly 400 clamps the glass, which would cause the clamping assembly 400 to loosen. After the glass is bonded, rotating the locking knob 107 in the opposite direction to move the locking knob 107 away from the rotating frame 300 releases the lock on the rotating frame 300, allowing the rotating frame 300 to rotate freely relative to the base 100. The operation is simple.

[0031] Please refer to Figure 2 and Figure 4 The clamping assembly 400 further includes a spring 408 sleeved on the clamping screw 404. The spring 408 abuts against the end of the lifting plate 402 away from the clamping knob 403 and drives the lifting plate 402 to move away from the cover plate 200. As the lifting plate 402 approaches the cover plate 200 under the drive of the clamping knob 403, the spring 408 is further compressed. After the glass is bonded, when the locking knob 107 is rotated in the opposite direction, the spring 408 gradually returns to its original length and pushes the lifting plate 402 to rise vertically, so that the clamping rod 406 automatically exits the window opening 201, preventing the clamping rod 406 from colliding with the cover plate 200 when the rotating frame 300 moves. The elastic force provided by the spring 408 keeps the lifting plate 402 abutting against the locking knob 107, which helps to improve the reliability of the clamping assembly 400.

[0032] Specifically, the clamping seat 401 is further provided with a vertical guide rod 409, which is spaced apart from the clamping screw 404, and the lifting plate 402 is provided with a guide hole 410 that cooperates with the guide rod 409. By providing the guide rod 409 on the clamping seat 401 and the guide hole 410 on the lifting plate 402 that cooperates with the guide rod 409, the movement direction of the lifting plate 402 on the clamping seat 401 is restricted, preventing the lifting plate 402 from tilting or deviating from the preset direction when moving, thus making the movement of the lifting plate 402 more stable.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, the rotating frame 300 is also provided with a sliding groove 303. The length direction of the sliding groove 303 is consistent with the length direction of the slot 301 and communicates with the slot 301. The pressing seat 401 is movably disposed in the sliding groove 303. The pressing seat 401 is configured to slide within the sliding groove 303 to adjust the position of the pressing assembly 400 on the rotating frame 300 and change the contact position between the flexible gasket 407 and the glass in the cavity 101, so that the contact position between the flexible gasket 407 and the glass is close to the air bubbles in the adhesive, ensuring that the air bubbles in the adhesive are squeezed out.

[0034] In this embodiment, the clamping seat 401 is further provided with a vertical second locking screw 411 and a locking nut 412 that cooperates with the second locking screw 411. The second locking screw 411 passes through the slide groove 303 and the slot 301. The locking nut 412 abuts against the side of the rotating frame 300 away from the clamping seat 401. By rotating the locking nut 412 to abut against the rotating frame 300, the position of the locking seat in the slide groove 303 can be locked, preventing the locking seat from moving unexpectedly in the slide groove 303. When it is necessary to adjust the position of the locking seat, simply rotate the locking nut 412 to move it away from the rotating frame 300, so that the position of the locking assembly on the rotating frame 300 can be easily adjusted.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
