Description

Technical Field

[0001] The utility model belongs to the technical field of hollow glass processing and inflation, and particularly relates to hollow glass processing and inflation equipment. Background Art

[0002] Insulating glass is a glass product made by bonding multiple sheets of glass to a metal frame using a high-strength, highly airtight composite adhesive. Due to its heat and sound insulation, aesthetics, practicality, and lightweight properties, it is widely used in buildings such as residences, hotels, and office buildings, as well as in equipment such as trains, automobiles, and ships. During the processing of insulating glass, inert gases such as argon and nitrogen are often injected into the glass to improve its sound and heat insulation properties and reduce the risk of deformation due to temperature and air pressure.

[0003] Insulating glass processing and filling equipment is a type of equipment used to fill insulating glass with inert gas. The Chinese utility model patent No. CN218062047U discloses an inert gas filling device for insulating glass processing. The application discloses an inert gas filling device for insulating glass processing, including a hollow glass body, an inflator for inflating the hollow glass body, an air supply device provided on the inflator, and an inflating mechanism provided on the inflator. The inflating mechanism includes a plurality of air pipes provided on the inflator, a metal tube provided at the end of the air pipe, and a gas supply device provided on the gas supply device. The utility model is an air guide head. By arranging an inflator, an air pipe, a metal air guide head, a fixed disc, a connecting plate, an elastic part, a clamping plate, a spring, an aluminum frame, an air hole, a sealing plug and an air supply device, the utility model solves the problem that the air pipe of the existing inflating device is directly inserted into the hole of the aluminum frame without fixing the air pipe, resulting in the air pipe being easily affected by external force and falling off from the air hole during the inflation and exhaust process, thereby reducing the inflation efficiency. At the same time, the sealing between the air pipe and the air hole is poor, resulting in reduced inflation and exhaust efficiency and low inert gas content inside the insulating glass.

[0004] However, in combination with the contents recorded in the specification and the drawings of the specification, it can be seen that the inert gas filling equipment for hollow glass processing disclosed in the application sets the elastic part, clamping plate, spring and other clamping components together with the metal air guide head. When in use, it is necessary to manually push the hollow glass body from one side of the groove, limit the hollow glass body by the limiting plate, insert the metal air guide head into the air hole, and at the same time, clamp the aluminum frame through the interaction of the two clamping plates and the spring.

[0005] The inert gas filling equipment for hollow glass processing disclosed in this application does not have the function of automatic clamping and loading and unloading, and cannot automatically clamp and load and unload the hollow glass to be inflated, which makes the loading and unloading strength of the hollow glass during the inflation process relatively large. At the same time, the hollow glass is easily shaken due to the small clamping force and the influence of the inflation airflow during the inflation process, which makes the inflation processing stability of the hollow glass poor.

[0006] Therefore, in view of the above technical problems, it is necessary to provide a hollow glass processing and inflation device.

[0007] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0008] The purpose of the utility model is to provide a hollow glass processing and inflating device, which can automatically clamp and load the hollow glass to be inflated.

[0009] In order to achieve the above-mentioned purpose, a specific embodiment of the present invention provides an insulated glass processing device, comprising: an inflator, a gas storage tank, a clamping guide mechanism, and an automatic clamping loading and unloading mechanism.

A plurality of groups of evenly distributed limiting side plates are integrally formed above the clamping base plate, and a plurality of groups of the limiting side plates cooperate to form a plurality of groups of grooves, and hollow glass bodies are slidably assembled in the plurality of groups of grooves. A support frame is fixedly assembled on one side of the clamping base plate close to the inflator, and a plurality of groups of evenly distributed metal air guide heads are slidably assembled on the support frame, and the metal air guide heads are arranged in coordination with the support frame.

[0012] The automatic clamping and loading and unloading mechanism is fixedly assembled on the outer side of the insulating glass body, and the automatic clamping and loading and unloading mechanism includes a pair of assembly base plates, and the pair of assembly base plates are fixedly connected to the side walls of the clamping base plates. A sliding fixing frame is slidably assembled on the top of the pair of assembly base plates, and a pair of clamping threaded rods are rotatably connected between the pair of sliding fixing frames. The outer sides of the pair of clamping threaded rods are threadedly connected to multiple groups of clamping fixing plates, and the multiple groups of clamping fixing plates are symmetrically arranged on both sides of the insulating glass body.

[0013] In one or more embodiments of the present invention, the bottoms of multiple groups of the grooves are each provided with an assembly avoidance groove. The assembly avoidance grooves provide space for the assembly and operation of multiple groups of support pulleys. Multiple groups of evenly distributed support pulleys are rotatably mounted within the assembly avoidance grooves. The multiple groups of support pulleys provide rolling support for the insulating glass body, thereby improving the smoothness of the sliding assembly of the insulating glass body. A limit block is fixedly mounted on the side of the groove proximal to the inflator. The limit block serves as a sliding limit for the insulating glass body.

[0014] In one or more embodiments of the present invention, a plurality of groups of metal gas guide heads are connected to the inflator via a connecting air pipe, through which gas is delivered to the metal gas guide heads.

[0015] In one or more embodiments of the present invention, a linear slide rail is fixedly mounted above the assembly base. The linear slide rail supports and guides the linear slider. A linear slider is slidably mounted above the linear slide rail and is fixedly connected to the bottom of the sliding bracket. The linear slider supports and limits the sliding bracket. Furthermore, the interaction between the linear slider and the linear slide rail provides sliding guidance for the sliding bracket.

[0016] In one or more embodiments of the present invention, a pair of sliding fixing frames are each fixedly connected to opposing sides of a sliding thread block. By guiding the sliding thread block, the movement of the sliding fixing frame is controlled, thereby facilitating the automatic loading and unloading of multiple sets of insulating glass bodies. The sliding thread block is internally threadedly connected to a sliding screw. This facilitates the sliding thread block to drive the sliding fixing frame to slide as the sliding screw rotates, driven by the internal and external threads.

[0017] In one or more embodiments of the present invention, both ends of the sliding screw are rotatably connected to a screw holder, the bottom of which is fixedly connected to the side wall of the assembly base. The screw holder serves as an assembly limiter for the sliding screw. A sliding drive motor is fixedly mounted on one side of the screw holder, and the output shaft of the sliding drive motor is in driving connection with the screw holder. The sliding drive motor provides power, and the sliding screw is rotationally driven by controlling the operation of the sliding drive motor.

[0018] In one or more embodiments of the present invention, a pair of clamping drive motors are fixedly mounted on one side of the sliding fixing frame. The output shafts of the clamping drive motors are drivingly connected to a pair of clamping threaded rods. The clamping drive motors provide power and, by controlling the operation of the clamping drive motors, rotate the clamping threaded rods, thereby enabling multiple clamping plates to clamp and secure the insulating glass body.

[0019] In one or more embodiments of the present invention, the clamping plates on both sides of the multiple sets of support frames are bored with internal threads in the same direction, and the clamping threaded rods on both sides of the multiple sets of support frames are bored with external threads in opposite directions. This facilitates the multiple sets of clamping plates to move in opposite directions as the clamping threaded rods rotate, under the action of the internal and external threads, thereby facilitating the clamping and fixing of the insulating glass body through the interaction of the multiple sets of clamping plates.

[0020] In one or more embodiments of the present invention, multiple sets of clamping plates are fixedly connected to a clamping pad on one side of the support frame. The provision of the clamping pad allows the multiple sets of clamping plates to flexibly clamp the insulating glass body, thereby reducing the risk of damage to the insulating glass body caused by external forces from the clamping plates.

[0021] In one or more embodiments of the present invention, a pair of threaded clamping rods are provided with position-limiting optical rods on both sides thereof. The position-limiting optical rods extend through the plurality of clamping plates, and both ends of the position-limiting optical rods are fixedly connected to the sliding fixing frame. The position-limiting optical rods serve as sliding guides for the plurality of clamping plates, thereby reducing the possibility that the plurality of clamping plates will rotate with the rotation of the threaded clamping rods due to the action of the threads.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0034] like Figures 1 to 7 As shown, an insulated glass processing and inflating device in one embodiment of the present invention includes: an inflator 1, a gas storage tank 101, a clamping guide mechanism 2, and an automatic clamping loading and unloading mechanism 3.

[0035] like Figure 1 As shown, one side of the inflator 1 is connected to a gas storage tank 101. The gas storage tank 101 plays the role of storing the gas to be filled.

[0036] like Figures 1 to 4As shown, the clamping guide mechanism 2 is fixedly assembled on one side of the inflator 1, and the clamping guide mechanism 2 includes a clamping base plate 201, which is fixedly assembled on one side of the inflator 1. The clamping base plate 201 supports and limits the positions of the multiple sets of insulating glass bodies 203.

[0037] like Figures 1 to 5 As shown, multiple sets of evenly distributed limiting side plates 202 are integrally formed above the clamping base plate 201, and multiple sets of limiting side plates 202 cooperate to form multiple sets of grooves. The multiple sets of grooves play a guiding role in the loading and unloading process of multiple sets of insulating glass bodies 203.

[0038] Specifically, the bottoms of the multiple groups of grooves are each provided with assembly avoidance grooves, which provide assembly and operation space for the multiple groups of support pulleys 206.

[0039] like Figures 6 and 7 As shown, multiple sets of evenly distributed support pulleys 206 are rotatably mounted within the assembly relief groove. These multiple sets of support pulleys 206 provide rolling support for the insulating glass body 203, improving the smoothness of the sliding assembly of the insulating glass body 203. A limit block 207 is fixedly mounted on the side of the groove closest to the inflator 1. The limit block 207 serves as a sliding limit for the insulating glass body 203.

[0040] like Figures 2 to 5 As shown, the hollow glass bodies 203 are slidably assembled in the plurality of grooves.

[0041] like Figures 2 to 5 As shown, a support frame 204 is fixedly mounted on one side of the clamping base plate 201 close to the inflator 1. The support frame 204 serves to limit the assembly of multiple sets of metal air guide heads 205.

[0042] like Figures 2 to 5 As shown, a plurality of evenly distributed metal gas guide heads 205 are slidably mounted on the support frame 204 , and the metal gas guide heads 205 are matched with the support frame 204 , so as to facilitate the inflation of the plurality of insulating glass bodies 203 through the plurality of metal gas guide heads 205 .

[0043] In addition, the gas filling ends of the multiple sets of metal gas guide heads 205 are equipped with sealing plugs to ensure the sealing between the metal gas guide heads 205 and the gas filling holes of the insulating glass body 203.

[0044] like Figures 6 and 7 As shown, a plurality of metal gas guide heads 205 are connected to the inflator 1 through a gas pipe 208. Gas is delivered to the metal gas guide heads 205 through the gas pipe 208.

[0045] like Figure 1As shown, the automatic clamping loading and unloading mechanism 3 is fixedly mounted on the outside of the insulating glass body 203. The automatic clamping loading and unloading mechanism 3 includes a pair of assembly bases 301, each of which is fixedly connected to the side walls of the clamping base 201. The assembly bases 301 serve as assembly limits and sliding guides for the sliding fixing frame 302.

[0046] like Figure 1 As shown, a pair of assembly base plates 301 are both slidably mounted with a sliding fixing frame 302. The sliding fixing frame 302 plays the role of assembly limit and horizontal sliding control for a pair of clamping threaded rods 303.

[0047] like Figure 1 As shown, a linear guide rail 305 is fixedly mounted on the top of the assembly base 301. The linear guide rail 305 supports and guides the linear slider 306.

[0048] like Figure 1 As shown, a linear slider 306 is slidably mounted above the linear guide rail 305. The linear slider 306 is fixedly connected to the bottom of the sliding bracket 302. The linear slider 306 supports and limits the sliding bracket 302. At the same time, the interaction between the linear slider 306 and the linear guide rail 305 guides the sliding of the sliding bracket 302.

[0049] like Figures 1 to 3 As shown, a pair of sliding fixing frames 302 are fixedly connected to the opposite sides with sliding screw blocks 307. By slidingly guiding the sliding screw blocks 307, the sliding fixing frames 302 are moved and controlled, thereby facilitating automatic loading and unloading of multiple sets of insulating glass bodies 203.

[0050] like Figures 1 to 3 As shown, the internal thread of the sliding thread block 307 is connected to the sliding screw 308. It is convenient for the sliding thread block 307 to drive the sliding fixing frame 302 to slide as the sliding screw 308 rotates under the action of the internal and external threads.

[0051] like Figures 1 to 3 As shown, both ends of the sliding screw 308 are rotatably connected to the screw fixing frame 309, and the bottom of the screw fixing frame 309 is fixedly connected to the side wall of the assembly base 301. The screw fixing frame 309 plays the role of assembly limit for the sliding screw 308.

[0052] like Figures 1 to 3 As shown, a sliding drive motor 310 is fixedly mounted on one side of the screw fixing bracket 309, and the output shaft of the sliding drive motor 310 is in driving connection with the screw fixing bracket 309. The sliding drive motor 310 provides power, and the sliding screw 308 is rotationally driven by controlling the operation of the sliding drive motor 310.

[0053] like Figures 2 to 3 As shown, a pair of sliding fixing frames 302 are rotatably connected with a pair of clamping threaded rods 303. The clamping threaded rods 303 play the role of supporting, limiting and moving control for multiple sets of clamping fixing plates 304.

[0054] like Figures 2 to 5 As shown, the outer sides of a pair of clamping threaded rods 303 are both threadedly connected to multiple sets of clamping fixing plates 304, which are symmetrically arranged on both sides of the insulating glass body 203. The insulating glass body 203 is clamped and fixed by controlling the movement of the multiple sets of clamping fixing plates 304.

[0055] It is noteworthy that the clamping plates 304 on both sides of the multiple support frames 204 have internal threads cut into them in the same direction, while the clamping threaded rods 303 on both sides of the multiple support frames 204 have external threads cut into them in opposite directions. This facilitates the multiple clamping plates 304 to move in opposite directions as the clamping threaded rods 303 rotate due to the internal and external threads, thereby facilitating the clamping and fixing of the insulating glass body 203 through the interaction of the multiple clamping plates 304.

[0056] like Figure 1 As shown, a pair of clamping drive motors 311 are fixedly mounted on one side of the sliding fixing frame 302. The output shafts of the clamping drive motors 311 are respectively drivingly connected to a pair of clamping threaded rods 303. The clamping drive motors 311 provide power. By controlling the operation of the clamping drive motors 311, the clamping threaded rods 303 are rotated, thereby enabling multiple clamping plates 304 to clamp and secure the insulating glass body 203.

[0057] like Figures 2 to 5 As shown, the multiple sets of clamping plates 304 are fixedly connected to the side close to the support frame 204 with a clamping pad 312. The provision of the clamping pad 312 allows the multiple sets of clamping plates 304 to flexibly clamp the insulating glass body 203, reducing the situation where the insulating glass body 203 is damaged by the external force of the clamping plates 304.

[0058] like Figures 1 to 5 As shown, a pair of clamping threaded rods 303 are provided with limiting polished rods 313 on both sides. The limiting polished rods 313 are provided through the multiple clamping fixing plates 304, and both ends of the limiting polished rods 313 are fixedly connected to the sliding fixing frame 302. The limiting polished rods 313 serve as sliding guides for the multiple clamping fixing plates 304, thereby reducing the possibility that the multiple clamping fixing plates 304 rotate with the rotation of the clamping threaded rods 303 under the action of the threads.

[0059] During specific use, the sliding screw 308 is driven to rotate by controlling the operation of the sliding drive motor 310. The sliding fixing frame 302 slides in the groove as the sliding screw 308 rotates under the action of the sliding thread block 307. The multi-assembly clamping fixing plate 304 is moved to the loading position of the groove by sliding the sliding fixing frame 302.

[0060] Subsequently, the insulating glass to be inflated is placed in the groove, and the pair of clamping drive motors 311 are controlled to rotate the pair of clamping threaded rods 303, thereby causing the multiple sets of clamping fixing plates 304 to move under the action of the internal and external threads, and the insulating glass body 203 in the groove is clamped and fixed by the multiple sets of clamping fixing plates 304. After clamping and fixing, the multiple sets of insulating glass bodies 203 can be moved until inflation occurs by controlling the sliding drive motor 310 to rotate in the opposite direction.

[0061] During the inflation process, the operator can manually insert the metal air guide head 205 into the inflation hole of the hollow glass body 203, or fix the metal air guide head 205 on the support frame 204 and insert the metal air guide head 205 into the inflation hole of the hollow glass body 203 by moving the sliding fixing frame 302.

[0062] When the metal gas guide head 205 is inserted into the inflation hole of the hollow glass body 203 , the hollow glass body 203 can be inflated or exhausted through the cooperation of the inflator 1 and the gas storage tank 101 .

[0063] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0064] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
