Technical Field

[0002] With the improvement of people's living standards, insulating glass has been widely used, especially in the home decoration industry, which has grown rapidly. At present, insulating glass has been widely used in various buildings to improve the thermal insulation and sound insulation performance of the building. The spacers sandwiched in the insulating glass are required to be able to absorb moisture, which requires the spacers to be filled with molecular sieves. Molecular sieves are used to absorb moisture and residual organic matter in the interlayer of the insulating glass, so that the insulating glass can still remain smooth and transparent at a lower temperature and have good thermal insulation performance.

[0003] In the production process of insulating glass, the molecular sieve filling device can be used to fill the spacer with molecular sieve, thereby improving the filling efficiency. When the molecular sieve filling device fills the spacer with molecular sieve, it is necessary to use a split clamp to clamp and lock the spacer. The guide of the translational motion of the split clamp generally adopts the form of optical axis + shaft sleeve, which has low precision, poor synchronization, and even has the problem of jamming.

[0060] The details of the present invention can be more clearly understood by combining the accompanying drawings with the description of the specific embodiments of the present invention. However, the specific embodiments of the present invention described herein are only used for the purpose of explaining the present invention and cannot be understood as limiting the present invention in any way. Under the guidance of the present invention, technicians can conceive of any possible variations based on the present invention, which should be considered to belong to the scope of the present invention.

[0061] In order to solve the problems of low precision and poor synchronization of split clamps, a molecular sieve filling device for hollow glass spacers is proposed in this application. Figure 3 This is a schematic diagram of the structure of the filling machine head in the embodiment of the utility model. Fig. 9 This is a schematic diagram of the structure of the split clamp assembly in the embodiment of the utility model. Fig.10 FIG. 1 is a partial exploded schematic diagram of a split clamp assembly in an embodiment of the utility model. Figure 3 , Fig. 9 and Fig.10As shown, the molecular sieve filling device for hollow glass spacers may include: a filling head 1. The filling head 1 may include a component mounting base 11, a drilling component 111 mounted on the component mounting base 11, a filling component 112 and a glue injection component 12.

[0062] The component mounting base 11 is used to be fixedly connected with other components, so as to fix the entire filling machine head 1. The component mounting base 11 may include component mounting seats 113 of different shapes, such as right-angled component mounting seats 113. The drilling assembly 111 is used to drill holes in the spacer to obtain injection holes; the filling assembly 112 is used to inject molecular sieves into the spacer through the injection holes; and the glue injection assembly 12 is used to inject glue to seal the injection holes of the spacer after the molecular sieves are injected.

[0063] As feasible, Figure 4 Schematic diagram of the structure of the component installation base, the drilling component 111 and the filling component 112 in the embodiment of the utility model, as shown Figure 4 As shown, the right-angled component mounting seat 113 can be respectively installed with the drilling component 111 and the filling component 112 on both sides, so as to realize the simultaneous drilling and filling of the molecular sieve on both sides of the spacer bar with the folded angle. The spacer bar can correspond to the component mounting seat 113, such as being close together, and the drilling component 111 drills the spacer bar to obtain the filling hole; then, the component mounting seat 113 is moved to align the filling component 112 with the filling hole, and the filling component 112 fills the spacer bar with the molecular sieve through the filling hole, and then the component mounting seat 26 is moved to align the glue injection component 12 with the filling hole, and the glue injection component 12 then injects glue to seal the filling hole of the spacer bar after the molecular sieve is filled.

[0064] The split clamp assembly 2 and the assembly mounting base 11 can be relatively displaced, so that the assembly mounting seat 26 and the split clamp assembly 2 can be relatively displaced to achieve the above-mentioned drilling, injection of molecular sieves and injection of glue plugging operations. The relative displacement can be a linear movement. In this case, the corresponding through holes of the drilling assembly 111, the injection assembly 112 and the glue injection assembly 12 are in a straight line.

[0065] like Figure 4 As shown, the filling component 112 can have a three-way structure, the first end of the three-way structure is a feed port for inputting molecular sieve, which can be connected to the storage tank 4; the second end of the three-way structure is a feed port, and the feed port is connected to the corresponding through hole of the filling component 112; the second end of the three-way structure is an air inlet for inputting gas, and the airflow can increase the flow speed of the molecular sieve, thereby improving the efficiency of filling the molecular sieve into the spacer strip.

[0066] like Fig. 9 and Fig.10As shown, the molecular sieve filling device for hollow glass spacers may include: a split clamp assembly 2 for clamping and fixing the spacers. The split clamp assembly 2 may include: a first split clamp 21 and a second split clamp 22 arranged in parallel; a plurality of support rods 23 for supporting the spacers passing through the first split clamp 21 and the second split clamp 22; a first linear sliding assembly 24 having a matching first linear guide and a first linear slider; a second linear sliding assembly 25 having a matching second linear guide and a second linear slider, the sliding direction of the first linear sliding assembly 24 being parallel to the sliding direction of the second linear sliding assembly 25; a mounting seat 26, one of the first linear sliding assemblies 24 being fixedly connected to the mounting seat 26, another of the first linear sliding assemblies 24 being fixedly connected to the first split clamp 21, one of the second linear sliding assemblies 25 being fixedly connected to the mounting seat 26, and another of the second linear sliding assemblies 25 being fixedly connected to the second split clamp 22; a linkage assembly; and a first driving mechanism 28.

[0067] The shape of the arrangement of the plurality of support rods 23 may correspond to the spacer bar. If the bend of the spacer bar needs to be supported, the shape of the arrangement of the plurality of support rods 23 is the same as the angle of the bend. For example, when the bend is 90 degrees, the shape of the arrangement of the plurality of support rods 23 may be a right angle, so that both sides of the spacer bar can be supported.

[0068] Among them, Fig.10 As shown, the linkage assembly may include a swing member 271; a rod body 272 passing through the swing member 271, and the swing member 271 can rotate around the rod body 272; a first driving rod 273 passing through one end of the swing member 271, and the first driving rod 273 is connected to another one of the first linear sliding components 24; a second driving rod passing through the other end of the swing member 271, and the second driving rod is connected to another one of the second linear sliding components 25, so that the other one of the first linear sliding components 24 generates reverse motion with the other one of the second linear sliding components 25 through the linkage assembly.

[0069] The first driving mechanism 28 is used to drive one of the first split clamping member 21 and the second split clamping member 22 to move along the sliding direction of the first linear sliding assembly 24 .

[0070] When the split clamp assembly 2 needs to clamp the spacer bar, the spacer bar is first placed on multiple support rods 23, and then the first driving mechanism 28 drives one of the first split clamping members 21 and the second split clamping members 22 to move along the sliding direction of the first linear sliding assembly 24, and one of the first split clamping members 21 and the second split clamping members 22 drives one end of the swing member 271 to rotate around the rod body 272 through one of the first linear sliding assemblies 24 fixedly connected to the first split clamping member 21. At this time, the other end of the swing member 271 drives the other of the first split clamping member 21 and the second split clamping member 22 to move along the sliding direction of the second linear sliding assembly 25 through one of the second linear sliding assemblies 25 fixedly connected to the second split clamping member 22. Driven by the linkage assembly in the above manner, the first split clamping member 21 and the second split clamping member 22 can both move towards each other under the action of the first driving mechanism 28, and the force on each component is reasonable. Coupled with the cooperation of the first linear sliding assembly 24 and the second linear sliding assembly 25, the moving directions of the first split clamping member 21 and the second split clamping member 22 will not be offset, thereby effectively improving the synchronization and accuracy of clamping and releasing of the first split clamping member 21 and the second split clamping member 22.

[0071] In the above embodiment, the rod 272 is connected to the mounting seat 26 or one of the second linear sliding components 25 or one of the first linear sliding components 24 .

[0072] In order to enable the swing member 271 to flexibly and accurately drive one of the linear sliding components to move along the sliding direction of the linear sliding component, such as Fig.10 As shown, a first opening and a second opening are respectively provided at both ends of the swing member 271, the first driving rod 273 passes through the first opening, and the second driving rod passes through the second opening. The length of the first opening in the extension direction of the swing member 271 is greater than the diameter of the first driving rod 273, and the length of the second opening in the extension direction of the swing member 271 is greater than the diameter of the second driving rod.

[0073] In the above embodiment, the first driving mechanism 28 can be installed on the first split clamping member 21, and the retractable driving rod of the first driving mechanism 28 passes through the first split clamping member 21 and is connected to the second split clamping member 22. The driving rod is connected to a joint 210, and the joint 210 passes through the second split clamping member 22 and is connected to the push-pull plate 29, and the push-pull plate 29 is connected to the side of the second split clamping member 22 facing away from the first split clamping member 21, so that the driving rod can directly drive the second split clamping member 22 to move along the sliding direction of the first linear sliding assembly 24.

[0074] As feasible, Fig. 9 and Fig.10As shown, the split clamp assembly 2 may include: a fixed seat 211, the fixed seat 211 and the mounting seat 26 are connected via a third linear sliding assembly 213; a second driving mechanism 212, which is used to drive the fixed seat 211 and the mounting seat 26 to produce relative motion in the vertical direction via the third linear sliding assembly 213. The third linear sliding assembly 213 may include a matching third linear guide rail and a third linear slider, one of which is connected to the mounting seat 26 and the other is installed on the fixed seat 211. The second driving mechanism 212 may be a cylinder, which may be fixedly mounted on the mounting seat 26. The end of the driving rod of the cylinder is connected to the fixed seat 211. The above structure can make the first split clamping member 21 and the second split clamping member 22 rise and fall, so as to adjust the height of the clamped spacer bar. When rising, the upward surface of the spacer bar can be in close contact with the downward surface of the component mounting base 11. When descending, the upward surface of the spacer bar can be separated from the downward surface of the component mounting base 11. Therefore, when the component mounting base 11 is translated, the spacer bar will not be scratched against the component mounting base 11, and the component mounting base 11 can smoothly enter the next working position.

[0075] As feasible, Figure 3 As shown, the component mounting base 11 and the split clamp assembly 2 can generate relative movement through the third driving mechanism 13, so that the first working position, the second working position and the third working position are formed between the component mounting base 11 and the split clamp assembly 2. In the first working position, the drilling assembly 111 can correspond to the spacer bar clamped by the split clamp assembly 2, so that the spacer bar can be drilled to obtain the injection hole. In the second working position, the filling assembly 112 can correspond to the spacer bar clamped by the split clamp assembly 2, so that the spacer bar can be injected with molecular sieve through the injection hole. In the third working position, the glue injection assembly 12 can correspond to the spacer bar clamped by the split clamp assembly 2, so that the injection hole of the spacer bar injected with the molecular sieve can be sealed with glue.

[0076] In order to effectively improve the accuracy of relative movement between the component mounting base 11 and the split clamp assembly 2 and the accuracy of position adjustment, the third driving mechanism 13 may include a motor 133 and a screw rod 131 connected to the motor 133; a driving member 132 with a threaded hole, the driving member 132 is connected to the component mounting base 11, and the screw rod 131 is screwed into the threaded hole to drive the component mounting base 11 to move.

[0077] In order to effectively ensure that the assembly mounting base 11 and the split fixture assembly 2 move relative to each other along a straight line, such as Figure 3As shown, the molecular sieve filling device for hollow glass spacers may include: a support seat 14, the support seat 14 is connected to the component mounting base 11 through a fourth linear sliding assembly 15 having a matching fourth linear guide rail and a fourth linear slider, the support seat 14 is connected to one of the fourth linear sliding assemblies 15, and the component mounting base 11 is connected to the other one of the fourth linear sliding assemblies 15.

[0078] Figure 6 FIG. 1 is a partial cross-sectional diagram of the glue injection assembly in the embodiment of the utility model. Figure 6 As shown, the glue injection assembly 12 may include: a glue injection valve 121. The glue injection valve 121 may include: a glue injection nozzle 1212 having a glue outlet; a glue injection valve stem 1213; a glue injection drive unit 1216 for driving the glue injection valve stem 1213 to move, so that the glue injection valve stem 1213 can open and close the glue outlet of the glue injection nozzle 1212; wherein, the inner side wall of the glue outlet has a first conical surface, and the outer side wall of the glue injection valve stem 1213 has a second conical surface that can be abutted and sealed with the first conical surface. Through the above structure, on the one hand, the guiding property of the glue injection valve stem 1213 when moving toward the glue injection nozzle 1212 and cooperating with the glue outlet to close can be increased, and on the other hand, when the second conical surface of the glue injection valve stem 1213 abuts against the first conical surface so that the glue outlet is closed, the problem of glue leakage from the glue injection nozzle 1212 can be effectively avoided.

[0079] Furthermore, the glue injection valve 121 may include: a glue injection valve body 1215 sleeved outside the glue injection valve stem 1213; a guide sleeve 1214 arranged between the glue injection valve body 1215 and the glue injection valve stem 1213; and a glue injection valve mounting base 1211, wherein the glue injection valve mounting base 1211 has a conveying channel connected to the glue outlet of the glue injection nozzle 1212, and the conveying channel is used to convey the sealant. The glue injection nozzle 1212, the glue injection valve stem 1213, the glue injection drive unit 1216, the glue injection valve body 1215, and the guide sleeve 1214 are all mounted on the glue injection valve mounting base 1211.

The interior of the cylinder 123 is connected to the delivery channel of the glue injection valve mounting base 1211.

[0082] The piston body 1223 can only move forward or backward inside the cylinder barrel 123 relative to the cylinder barrel 123. The piston joint 1224 can be screwed on the cylinder rod 1225. In order to ensure that it will not be separated in the later stage, a nut 1226 can also be screwed on the cylinder rod 1225, and the nut 1226 is tightly against the piston joint 1224. The piston joint 1224 can move forward or backward relative to the cylinder barrel 123, and can also produce a small amount of unique movement in the diameter direction of the cylinder barrel 123. The thrust and pull of the cylinder rod 1225 are transmitted between the piston body 1223 and the piston joint 1224 through the bayonet 1228. The piston body 1223 and the cylinder rod 1225 are not fixed in the diameter direction of the cylinder barrel 123, and a small amount of floating can be relatively generated, so that the eccentricity caused by the error of the parts and the error of the installation can be compensated.

[0083] As a feasible method, the outer wall of the cylinder 123 may have an annular groove, in which a wear-resistant ring 1227 is disposed, and the outer wall of the wear-resistant ring 1227 protrudes from the outer wall of the cylinder 123. The wear-resistant ring 1227 may be made of a wear-resistant and low-resistance material, thereby increasing the life of the cylinder 123. In order to improve the sealing performance, a sealing ring 1222 may be disposed at the edge of the end of the piston body 1223, and the sealing ring 1222 may be pressed by a pressure cap 1221 disposed at the end of the piston body 1223. The pressure cap 1221 may be directly connected and fixed to the piston body 1223 using bolts or the like.

[0084] As feasible, Figure 1 The structure of the molecular sieve filling device for hollow glass spacer in the embodiment of the utility model is shown in FIG. Figure 1 , Figure 2 The structure of the molecular sieve filling device for hollow glass spacer in the embodiment of the utility model is shown in FIG. Figure 2 , Fig.11 Schematic diagram of the structure of the frame assembly in the embodiment of the utility model, as shown in Figure 1 , Figure 2 and Fig.11As shown, the molecular sieve filling device for hollow glass spacers may include: a frame assembly 3. The frame assembly 3 can be raised and lowered in the vertical direction, and the filling head 1 can be installed on the frame assembly 3, so that the filling head 1 can be raised and lowered in the vertical direction to change the height of the filling head 1, so as to adapt to the size of different spacer frames.

[0085] Further, such as Fig.11 As shown, the rack assembly 3 may include: two parallel and spaced lifting mechanisms 31 and a rack drive unit 32. Fig.12 Schematic diagram of the structure of the connection base in the embodiment of the utility model, as shown in Fig.11 and Fig.12 As shown, at least one lifting mechanism 31 may include: an outer guide rail 311; an inner guide rail 312 matched with the outer guide rail 311, and the inner guide rail 312 can be lifted and slid relative to the outer guide rail 311; a connecting base 313 matched with the outer guide rail 311, and the connecting base 313 can be lifted and slid relative to the inner guide rail 312. The filling head 1 can be installed on the connecting base 313. Through the above structure, the filling head 1 can be displaced to a large extent in the vertical direction.

[0086] In order to drive the inner guide rail 312 to move up and down relative to the outer guide rail 311, and the connection base 313 to move up and down relative to the inner guide rail 312, it is feasible to drive the inner guide rail 312 to move up and down relative to the outer guide rail 311. Fig.11 As shown, the lifting mechanism 31 may further include: a driving sprocket 314 installed on the inner guide rail 312, the frame driving unit 32 drives the driving sprocket 314 to rotate; a chain 315 installed on the outer guide rail 311 and extending along the extension direction of the outer guide rail 311, and the driving sprocket 314 is meshed with the chain 315. When the frame driving unit 32 drives the driving sprocket 314 to rotate, the driving sprocket 314 can drive the inner guide rail 312 to move up and down under the action of the chain 315.

[0087] In order to prevent the chain 315 from loosening and separating from the driving sprocket 314, two idler wheels 316 can be directly or indirectly installed on the inner guide rail 312, and the idler wheels 316 are respectively located above and below the driving sprocket 314. The chain 315 first partially engages with the upper idler wheel 316 and then passes between the upper idler wheel 316 and the driving sprocket 314, then bypasses part of the driving sprocket 314 and engages with part of the driving sprocket 314, and then passes between the lower idler wheel 316 and the driving sprocket 314 and then partially engages with the lower idler wheel 316. The upper and lower ends of the chain 315 are fixed and tightened, so that the chain 315 is tightly engaged with the idler wheel 316 and the driving sprocket 314, so that the two idler wheels 316 limit the chain 315 to a certain extent, so that the chain 315 cannot be separated from the driving sprocket 314.

[0088] As feasible, Fig.11 As shown, the lifting mechanism 31 may also include: a first pulley 317 arranged on the inner track and a second pulley 318 located below the first pulley 317; a traction rope 319, which passes around the first pulley 317 and the second pulley 318 and then has its two ends respectively connected to the connecting base 313, such as the connection to the first position 320 of the connecting base 313, and one part of the traction rope 319 is fixed to the outer guide rail 311, such as the second position 321 of the outer guide rail 311.

[0089] In this embodiment, the traction rope 319 and the connection base 313 form a closed circle and can move around the first pulley 317 and the second pulley 318. The traction rope 319 generally forms two vertically extending parallel sections, the position where the traction rope 319 is connected to the connection base 313 is located on one section of the traction rope 319, and the position where the traction rope 319 is fixed to the outer guide rail 311 is located on the other section of the traction rope 319. For example, when the rack drive unit 32 drives the driving sprocket 314 to rotate, the driving sprocket 314 drives the inner guide rail 312 to rise under the action of the chain 315. At this time, a portion of the traction rope 319 is fixed to the outer guide rail 311. As the inner guide rail 312 rises, the length of the traction rope 319 between the first pulley 317 and the portion where the traction rope 319 and the outer guide rail 311 are fixed increases. The traction rope 319 pulls the connection base 313 upward again to move the connection base 313 upward. The length of the traction rope 319 between the connection base 313 and the second pulley 318 increases, and the length of the traction rope 319 between the second pulley 318 and the portion where the traction rope 319 and the outer guide rail 311 are fixed decreases. The process in which the driving sprocket 314 drives the inner guide rail 312 to descend under the action of the chain 315 is similar to the above process and will not be repeated here. Through the above structure, when the frame driving unit 32 drives the active sprocket 314 to rotate so that the inner guide rail 312 moves a distance A, the connecting base 313 can further move a distance 2A. In this way, the purpose of doubling the stroke is achieved, and the adjustment range of the filling head 1 can be further greatly increased.

[0090] As feasible, Figure 1 and Figure 2 As shown, the molecular sieve filling device for hollow glass spacers may include: a storage tank 4, which is used to store the molecular sieve and deliver the molecular sieve to the first end of the three-way structure of the filling head 1.

As feasible, the molecular sieve filling device for hollow glass spacers may include: a negative pressure generating device 7, which is used to generate negative pressure, so as to suck the molecular sieve in the barrel 6 and input it into the storage tank 4. When the molecular sieve in the storage tank 4 reaches a low level, the negative pressure generating device 7 starts to operate to input the molecular sieve into the storage tank 4.

[0092] As feasible, Figure 1 and Figure 2 As shown, the molecular sieve filling device for hollow glass spacers may include: a control box 5, which is electrically connected to the drilling component 111, the filling component 112, the glue injection component 12, each driving mechanism, each driving unit, the negative pressure generating device 7, etc., so as to realize the control and power supply of the above-mentioned components.

[0093] As feasible, Figure 1 and Figure 2 As shown, the frame assembly 3 can be connected and installed on the support base 8, so that the frame assembly 3 remains stable. The storage tank 4, the barrel 6, the negative pressure generating device 7, the control box 5 and other components can also be installed on the support base 8. In order to facilitate the movement of the support base 8, a plurality of rolling wheels can be installed at the bottom of the support base 8.
