[0002] To improve the thermal insulation effect of insulated glass, there is a technology that applies a thermoplastic spacer strip between the insulated glass panes to reduce the thermal conductivity coefficient and achieve a complete seal. The formation of the thermoplastic spacer strip requires an adhesive applicator to apply adhesive onto the glass. After completing one application process, it is necessary to control the nozzle to close to prevent leakage of the fluid adhesive. However, the nozzle in the relevant technology has the problem of adhesive leakage outside the application process. Summary of the Invention

The sealing strip is disposed at the first opening and is movably connected to the main body along the second direction. The sealing strip includes a second sealing surface, and the first and second sealing surfaces face each other along the second direction. The adjusting mechanism is connected to the sealing strip and is used to drive the sealing strip to reciprocate along the second direction to open or block the first opening.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] refer to Figures 1 to 7 According to a first aspect embodiment of the present invention, a glue applicator head 100 includes a main body 101, a sealing strip 102, and an adjusting mechanism 103. A glue channel 401 is provided within the main body 101. The glue channel 401 includes a glue outlet 402. The glue outlet 402 has a first opening 403 on one side along a first direction and a second opening 404 on one side along a second direction. The first and second directions intersect. The inner wall of the glue channel 401 along the second direction includes a first sealing surface 405. The sealing strip 102 is disposed at the first opening 403 and is movably connected to the main body 101 along the second direction. The sealing strip 102 includes a second sealing surface 406. Along the second direction, the first sealing surface 405 and the second sealing surface 406 are arranged facing each other. Adjustment mechanism 103 is connected to sealing strip 102. Adjustment mechanism 103 is used to drive sealing strip 102 to reciprocate along the second direction to open or block the first opening 403. When sealing strip 102 opens the first opening 403, sealing strip 102 opens the second opening 404 (e.g., Figure 4 and Figure 5 As shown), the movement of the sealing strip 102 in the second direction can adjust the opening height of the glue outlet 402 in the second direction. When the sealing strip 102 blocks the first opening 403, the sealing strip 102 also blocks the second opening 404 (as shown). Figure 6 and Figure 7As shown in the figure, the first sealing surface 405 and the second sealing surface 406 are in contact. In this embodiment of the glue applicator head 100, a second sealing surface 406 is also provided on one side of the sealing strip 102 along the second direction, and a first sealing surface 405 is provided on the inner wall of the glue channel 401 along the second direction. When the sealing strip 102 moves along the second direction to block the glue outlet 402, the first sealing surface 405 and the second sealing surface 406 located in the glue channel 401 are in contact, preventing gaps between the sealing strip 102 and the main body 101 where the second opening 404 is located, thereby reducing the leakage of glue from the gap in the second opening 404 and effectively solving the glue leakage problem at the glue outlet 402. This facilitates the continuous operation of the glue applicator process and helps improve work efficiency.

[0031] Specifically, refer to Figure 7 If the sealing strip 102 only includes the sealing part 407, then when the sealing strip 102 is in Figure 7 When the position is shown, the sealing of the adhesive in the second opening 404 is achieved by the upper end face of the sealing part 407 adhering to the lower end face of the second wall 202. However, since the sealing part 407 moves along the second direction, the two end faces cannot be interference-fitted. To avoid damage caused by the end of the sealing part 407 directly hitting the inner wall of the adhesive channel 401 when sealing the first opening 403, the degree of adhesion at this point is not high, and there are often gaps. These gaps can easily lead to adhesive leakage. In this application, a raised sealing part 408 is provided on the sealing part 407, and a second sealing surface 406 is provided on one side of the sealing part 408 along the second direction. A first sealing surface 405 is also additionally machined on the inner wall of the adhesive channel 401. When the sealing strip 102 seals the first opening 403, the position of the sealing strip 102 is as follows: Figure 7 As shown, the first sealing surface 405 and the second sealing surface 406 are bonded together within the glue channel 401, thereby increasing the bonding area between the sealing strip 102 and the glue outlet 402 at the second opening 404, thus improving the anti-leakage effect and reducing the glue leakage problem at the glue outlet 402.

[0032] It should be noted that, Figure 3 The exploded view is mainly an exploded schematic diagram of the main body 101 and its internal and surrounding structures. In order to better show the specific structure of the first guide block 301, the second guide block 410 in the glue channel 401 and the movable part 108 in the adjustment mechanism 103 below the main body 101.

[0033] refer to Figures 4 to 7In some embodiments of the present invention, the sealing strip 102 includes a plugging portion 407 and a sealing portion 408 connected to each other. The sealing portion 408 protrudes into the adhesive channel 401 relative to the plugging portion 407. A second sealing surface 406 is provided at one end of the sealing portion 408 along the second direction. The plugging portion 407 extends along the second direction and is connected to the adjustment mechanism 103. The sealing strip 102 in the prior art is equivalent to having only a smooth plugging portion 407. The embodiments of this application add a plugging portion 407 protruding into the adhesive channel 401, which allows for better processing of the second sealing surface 406 to fit against the first sealing surface 405 inside the adhesive channel 401. Furthermore, the addition of the sealing portion 408 does not affect the sliding of the original plugging portion 407 in the second direction. Further, refer to... Figure 5 and Figure 7 In some embodiments, the sealing part 408 and the blocking part 407 are spaced apart at their ends in the second direction. When the sealing strip 102 blocks the first opening 403, the end of the blocking part 407 in the second direction protrudes slightly relative to the second wall 202. At this time, the first sealing surface 405 and the second sealing surface 406 are in contact. This ensures that the sealing strip 102 blocks the first opening 403 and also blocks the second opening 404 (through the contact between the first sealing surface 405 and the second sealing surface 406, and the contact between the upper surface of the blocking part 407 and the lower surface of the second opening 404). The blocking effects of the two will not interfere with each other, thus improving the blocking effect.

[0034] It should be noted that, Figure 4 and Figure 6 The hollow arrow in the middle indicates the direction of glue discharge in glue channel 401.

[0035] refer to Figure 2 , Figure 5 and Figure 7 In some embodiments of the present invention, one end of the sealing portion 407 along the second direction is used to seal the second opening 404, and a relief surface 601 is provided, which is recessed in the opposite direction to the second direction. During the dispensing process, the adhesive outlet 402 will flow out from the first opening 403 and the second opening 404 respectively. When the adhesive flows out from the first opening 403 along the first direction, it may adhere to... Figure 5 The sealing strip 102 shown is positioned at one end along the second direction, and therefore a clearance surface 601 is provided at that location. The three-dimensional structure of the clearance surface 601 is as follows: Figure 2 As shown, the cross-sectional structure is as follows Figure 5 As shown, the recessed design of the avoidance surface 601 can, to a certain extent, prevent adhesive from adhering to the sealing strip 102, thereby reducing the frequency of adhesive leakage and cleaning, and improving work efficiency.

[0036] refer to Figure 1 , Figure 2, Figure 5 , Figure 7 In some embodiments of the present invention, the main body 101 includes a first wall 201 and a second wall 202, the first wall 201 and the second wall 202 together form an adhesive outlet 402, a first opening 403 is disposed on the first wall 201, and a second opening 404 is disposed on the second wall 202. Figure 1 and Figure 2 The structure of the first wall 201 and the second wall 202 can be seen. The first wall 201 and the second wall 202 are machined separately on the main body 101, which facilitates the manufacturing of the first opening 403 and the second opening 404. Furthermore, in some embodiments, the first wall 201 and the second wall 202 are perpendicular to each other, thereby ensuring that the first opening 403 and the second opening 404 are also perpendicular to each other. (Reference) Figure 2 It can be seen that the second wall 202 is not on the same straight line as its adjacent wall, and the area of ​​the second wall 202 is relatively small. This is because during the process of applying adhesive to the glass, the surface of the second wall 202 faces the glass directly. The length and width of the second opening 404 determine the width of the adhesive strip when applying adhesive to the glass, while the size of the first opening 403 determines the height of the adhesive strip. Therefore, the second wall 202, which is not on the same straight line as its adjacent wall, can be surface-treated separately to achieve a higher degree of flatness and ensure that the adhesive strip is in a regular shape.

[0037] refer to Figures 3 to 7 In some embodiments of the present invention, the glue channel 401 includes a third wall 409, and a first sealing surface 405 is disposed on the third wall 409. The glue applicator head 100 includes at least one of the following: a. with the plane containing the second wall 202 as a reference plane, the slope of the first sealing surface 405 is greater than the slope of the third wall 409 (e.g., ...). Figure 5 (as shown); b. The surface roughness of the first sealing surface 405 is less than the surface roughness of the remaining inner walls of the sealant channel 401; c. The second sealing surface 406 is parallel to the first sealing surface 405 (as shown). Figure 7 (As shown). Solution a can increase the size of the second opening 404 along the first direction. As mentioned earlier, the second wall 202 and the second opening 404 face the glass directly. Therefore, the size of the second opening 404 determines the size of the adhesive strip. Increasing the size of the second opening 404 along the first direction can effectively improve the adhesive dispensing efficiency and the dispensing length within the same time. (Refer to...) Figure 5 It can be seen that if the slope of the first sealing surface 405 is equal to the slope of the third wall 409, then without changing the wall thickness of the glue channel 401, the first sealing surface 405 extending to the second opening 404 will necessarily make the second opening 404 smaller than... Figure 5The dimensions shown are smaller. Option b aims to further improve the fit between the first sealing surface 405 and the second sealing surface 406, thereby enhancing their sealing effect on the adhesive. Furthermore, the second sealing surface 406 can also be designed to have a smaller surface roughness than other walls of the sealing portion 408. Since the areas of the first sealing surface 405 and the second sealing surface 406 are not large, processing will not require excessive effort. Option c also improves the sealing effect between the first sealing surface 405 and the second sealing surface 406; their parallel alignment allows for a smoother seal upon contact. Figure 7 The diagram shows a surface seal. If the two lines are not parallel, it is a line seal (i.e., intersecting lines). Although it can still achieve sealing, the sealing effect is relatively low.

[0038] refer to Figures 3 to 4 In some embodiments of the present invention, the glue applicator head 100 further includes a first glue guide block 301, which is disposed within the glue channel 401 and forms a glue guiding channel. Along the second direction, the width of the glue guiding channel gradually increases at the end near the glue outlet 402. And / or, the glue applicator head 100 further includes a second glue guide block 410. The inner wall of the glue channel 401 includes a third wall 409 and a fourth wall 411 connected to each other. The third wall 409 and the fourth wall 411 form a corner section 412. The second glue guide block 410 is disposed at the corner section 412. A bending surface 413 is provided on the side of the second glue guide block 410 facing away from the third wall 409 and the fourth wall 411. The bending surface 413 is inclined from the fourth wall 411 towards the third wall 409. The glue guiding channel formed by the first glue guide block 301 refers to... Figure 3 The space formed by the spaced arrangement of two identical components of the first adhesive guide block 301 shown. Figure 3 As can be seen, the adhesive channel gradually widens along the direction near the adhesive outlet 402, corresponding to Figure 4 The second adhesive guide block 301 is positioned within the adhesive channel 401 corresponding to the third wall 409, gradually widening along the second direction. This design allows the channel for adhesive flow to the outlet 402 to gradually increase, reducing flow pressure and preventing excessive or rapid adhesive outflow from the outlet 402. This improves the controllability of adhesive flow rate and volume, thereby enhancing adhesive quality. During the sealing process, as the sealing strip 102 approaches the outlet 402, the flow rate and pressure of the adhesive on its surface decrease, better sealing the outlet 402 and preventing leakage. The three-dimensional shape of the second adhesive guide block 410 is as follows... Figure 3 As shown, the setting location is as follows Figure 4The adhesive channel 401 is formed at the corner segment 412 where the third wall 409 and the fourth wall 411 meet. A second adhesive guide block 410 is used to shape the adhesive channel 401, preventing adhesive from accumulating in the corner segment 412. The bent surface 413 of the second adhesive guide block 410 provides excellent guidance, allowing the adhesive to flow as far as possible towards the outlet 402. It should be noted that in some embodiments, the bent surface 413 can be... Figure 4 The curved surface shown can also be a slope. The slope still has a good guiding and anti-accumulation function relative to the vertical corner segment 412.

[0039] refer to Figures 1 to 4 as well as Figure 6 In some embodiments of the present invention, the adjusting mechanism 103 includes a driving assembly and a movable member 108. The driving assembly is connected to the main body 101, and the movable member 108 can reciprocate relative to the main body 101 along a second direction. The glue applicator head 100 also includes a limiting block 415. The limiting block 415 and the sealing strip 102 are both connected to the movable member 108. A first limiting groove 418 is formed on the side of the main body 101 facing the movable member 108. The first limiting groove 418 extends along the second direction. At least a portion of the limiting block 415 is located within the first limiting groove 418 and can slide relative to the first limiting groove 418. When the limiting block 415 abuts against the inner wall of the first limiting groove 418 along the second direction, the first sealing surface 405 and the second sealing surface 406 are in contact (e.g., Figure 7 (As shown). The limiting block 415 prevents the sealing strip 102 from failing to stop moving in time during the sealing process, thus preventing the sealing part 408 from impacting the inside of the glue channel 401, which could cause the first sealing surface 405 and the second sealing surface 406 to collide and be damaged. During the movement of the sealing strip 102 driven by the moving part 108, the limiting block 415 also moves within the limiting groove. When the limiting block 415 abuts against the inner wall of the limiting groove, that is... Figure 6 In the case shown, the first sealing surface 405 fits perfectly against the second sealing surface 406, which increases the limiting function and improves the safety performance.

[0040] refer to Figures 1 to 4In some embodiments of the present invention, the drive assembly includes a drive member 104 and a gear 414, the movable member 108 includes a rack 416 and a guide portion 417, the sealing strip 102 is connected to the rack 416, the main body 101 is provided with a guide groove 203 along a second direction, the guide portion 417 is detachably disposed in the guide groove 203 and extends along the second direction, the guide portion 417 is used to support and guide the rack 416, the drive member 104 is connected to the main body 101, the power end of the drive member 104 is coaxially connected to the gear 414, the gear 414 meshes with the rack 416, the drive member 104 drives the gear 414 to rotate, so that the gear 414 drives the sealing strip 102 to move through the rack 416. The gear 414 and rack 416 transmission process is smoother, which is beneficial for the sealing strip 102 to block or open the glue outlet 402. It also has a long service life and does not require frequent replacement. The guide part 417 ensures that the rack 416 moves in the second direction, improving the accuracy of the movement process and enabling the sealing strip 102 to accurately block or open the glue outlet 402. In some embodiments, the gear 414 and rack 416 transmission can also be replaced by a worm gear or lead screw structure.

[0041] refer to Figures 1 to 3 In some embodiments of the present invention, the glue applicator head 100 further includes a base 105, a disassembly plate 106, and a locking component. The base 105 is detachably connected to both the main body 101 and the disassembly plate 106. At least one limiting post is provided through the base 105. Figure 3(Dotted lines on the base 105 are shown in the figure). The disassembly plate 106 is recessed with quick-installation holes 107 along the disassembly direction. When the quick-installation holes 107 slide relative to the base 105 along the installation direction until they are engaged with the outer periphery of the limiting post, the locking element (not shown in the figure) can connect the disassembly plate 106 to the base 105; and / or, the glue applicator head 100 also includes a heating element (not shown in the figure), a temperature sensor, and a heat insulation plate 302. The outer surface of the main body 101 has multiple mounting holes 303. The heating element is disposed in the mounting holes 303. The heating element is used for Heating the glue channel 401, a temperature sensor is used to detect the glue temperature at the glue outlet 402 or the glue temperature inside the glue channel 401. A heat insulation plate 302 is disposed on the outer surface of the main body 101 and covers the mounting hole 303. The temperature sensor is connected to the main body 101 to detect the temperature of the main body 101 and thus reflect the glue temperature inside the glue channel 401. It can also be connected near the first wall 201 or the second wall 202 to detect the temperature of the first wall 201 or the second wall 202 and thus reflect the glue temperature at the glue outlet 402. The function of the disassembly plate 106 is to restrict or release the connection between the glue applicator head 100 and the glue applicator. When the disassembly plate 106 is installed on the base 105, the main body 101, the base 105, and the disassembly plate 106 itself are all connected to the glue applicator. After the disassembly plate 106 is removed, the base 105 and the main body 101 can be removed from the glue applicator assembly along the limiting post. Therefore, the disassembly plate 106 is designed with a quick-installation hole 107 recessed to facilitate quick disassembly and assembly. The disassembly plate 106 moves towards the limiting post along the installation direction. When it is in place, the limiting post will naturally engage with the quick-installation hole 107. There is no need for manual positioning. Then, the locking device can be used to lock it. When disassembling, it is only necessary to remove the locking device and then move the disassembly plate 106 away from the limiting post radially. The disassembly and assembly speed is fast, which improves the work efficiency when replacing or repairing the glue applicator head 100. It should be noted that in some embodiments, the limiting post can be a screw rod, and the locking component can be a nut that can be sleeved on the limiting post. In this way, it is only necessary to snap the disassembly plate 106 into place and tighten the disassembly plate 106, the base 105 and the glue application device assembly by using the nut. The disassembly and installation process is relatively convenient. In some embodiments, additional locking mechanisms such as buckles and locking pins can also be provided to lock the disassembly plate 106.The mounting hole 303 is for placing the heating element. Because the adhesive used on the spacer of the insulating glass often has high viscosity, it needs to be kept at a certain temperature to prevent it from drying and hardening, and it needs to maintain good fluidity. Therefore, the mounting hole 303 and the heating element can heat the adhesive channel 401 more deeply, thereby heating the adhesive in the adhesive channel 401 and improving the quality of adhesive dispensing. The temperature sensor can also achieve precise temperature control of the heating process. After the sealing strip 102 seals the adhesive outlet 402, the heating element can also prevent the adhesive left in the adhesive channel 401 from solidifying and hardening. The heat insulation plate 302 is to prevent heat from spreading to the environment, thereby improving the heat utilization rate and safety performance.

[0042] According to a second aspect embodiment of the present invention, an adhesive applicator is used for applying adhesive to spacer strips in insulating glass, including an adhesive applicator head 100 as described in any of the first aspect embodiments. In related technologies, the sealing strip 102 only seals both the first opening 403 and the second opening 404 by being positioned at the first opening 403 and moving along the second direction. However, in practice, this sealing effect is only good for the first opening 403, but poor for the second opening 404. A gap exists between the sealing strip 102 and the main body 101 where the second opening 404 is located. In actual use, this gap easily leads to adhesive leakage, which is detrimental to subsequent adhesive application processes. Excessive leakage requires adhesive removal, resulting in low work efficiency. The sealing strip 102 of this application embodiment has a second sealing surface 406 on one side in the second direction, and a first sealing surface 405 is provided on the inner wall of the glue channel 401 along the second direction. When the sealing strip 102 moves along the second direction to block the glue outlet 402, the first sealing surface 405 and the second sealing surface 406 located in the glue channel 401 fit together, thereby reducing the phenomenon of glue leakage from the gap of the second opening 404 and reducing the glue leakage problem of the glue outlet 402. The glue application device using the glue applicator head 100 can also reduce glue leakage and glue removal frequency, and improve work efficiency.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
