Description

Technical Field

[0001] This invention relates to the field of insulated glass manufacturing for doors and windows, and more particularly to an automatic glue application production line for TPSS thermoplastic warm edge spacers for insulated glass in doors and windows. Background Technology

[0002] Insulating glass is a new type of building material that offers excellent heat insulation, sound insulation, aesthetic appeal, and reduces building weight. Most commercially available insulating glass consists of two or more panes of glass with a metal spacer between them to form a hollow layer, sealed with two layers of sealant. While the metal spacer provides a reasonable hollow layer thickness and lifespan, its rapid heat conduction creates thermal bridges during indoor-outdoor temperature convection, significantly reducing the glass's insulation performance. Therefore, with technological advancements and considerations such as energy consumption, TPSS thermoplastic warm-edge spacers have emerged.

[0003] Currently, the TPSS thermoplastic warm-edge spacer strip glue application production line mainly includes glue application, trimming, and heating processes. While the glue application can be completed through these processes, the following problems still exist:

[0004] Firstly, during glass conveying, in order to accommodate glass of different sizes, at least seven or eight rows of rollers are set on the support frame to support and guide the glass using a bottom-dense, top-combing method. However, dust easily accumulates on the rollers, causing large areas of the glass in contact with the rollers to be stuck with the dust. If it is not cleaned, it will easily affect the sales quality. Cleaning is quite troublesome.

[0005] Secondly, since thermoplastic spacers have been used instead of metal spacers, higher requirements have been placed on the continuity of glue supply and the accuracy of glue application during production. However, existing insulating glass glue application production lines cannot meet these requirements well, which makes it easy for the produced insulating glass to have problems such as poor sealing and air leakage. In addition, existing glue application mechanisms also have defects such as low glue application efficiency.

[0006] Third, the existing heating section has a relatively complex structure and cannot effectively support and heat glass of different sizes, which limits its application. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, the present invention provides an automatic glue application production line for TPSS thermoplastic warm edge spacer strips for insulated glass in doors and windows, which at least solves or alleviates a problem existing in the prior art, or at least provides a beneficial alternative.

[0008] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0009] An automatic glue application production line for TPSS thermoplastic warm edge spacer strips for insulated glass in doors and windows includes a front conveying section, a glue application section, a rear conveying section, a trimming section, and a heating section arranged sequentially along the production direction.

[0010] The front conveying section, glue application section, rear conveying section and trimming section each include a conveyor frame. An air guide plate is fixedly inclined on the front side of the conveyor frame. The air guide plate is provided with multiple rows of air slits running through it from top to bottom. The air slits are set from back to front and inclined upward. An air supply pipe is provided on the rear side of the air guide plate corresponding to the air slits and connected to it. The air supply pipe is connected to the air flotation fan.

[0011] The front conveying section, rear conveying section, and trimming section each have a first conveying mechanism below their air guide plates that cooperate with them to convey glass. The glue-applying section has a second conveying mechanism below its air guide plate that cooperates with it to convey glass. The second conveying mechanism includes a conveying beam fixed to the conveyor frame. The front side of the conveying beam has two synchronous conveyor belt mechanisms along the conveying direction. A glue-scraping device is installed between the two synchronous belt conveyor mechanisms. The top of the conveying beam has a suction cup conveyor belt mechanism with the conveying surface of the suction cup conveyor belt mechanism facing forward and the conveying surface of the synchronous belt conveyor mechanism facing upward. Several first backrest wheels for supporting the glass are also provided on the conveying beam below the suction cup conveyor belt mechanism to prevent the glass from sticking tightly to the conveying surface of the suction cup conveyor belt mechanism.

[0012] In one example, the suction cup conveyor belt mechanism includes a suction cup conveyor belt driven by a first driving member and supported by a first tensioning support member located behind its conveying surface, the suction cup conveyor belt being drawn by an adsorption fan; the synchronous conveyor belt mechanism includes a synchronous conveyor belt driven by a second driving member and supported by a second tensioning support member located below its conveying surface.

[0013] To ensure precise synchronization, the two drive wheels of the two second drive components are connected by a belt, and one of the drive wheels is connected to a servo motor. The first tensioning support includes a first support beam fixed to the top of the conveyor beam, and a first guide plate is fixed to the front side of the first support beam to limit the upper and lower sides of the suction cup conveyor belt; the second tensioning support includes a second support beam fixed to the front side of the conveyor beam, and a second guide plate is fixed to the top of the second support beam to limit the front and rear sides of the synchronous conveyor belt.

[0014] In one example, the first backrest wheel is fixed by an adjustable mounting base. Specifically, the adjustable mounting base includes an L-shaped fixing plate. The outer side of the vertical plate of the L-shaped fixing plate is connected to a wheel seat for mounting the first backrest wheel. A strip-shaped adjustment hole is provided on the horizontal plate of the L-shaped fixing plate. The L-shaped fixing plate is positioned and fixed on the conveyor beam by bolts that cooperate with the strip-shaped adjustment hole.

[0015] Furthermore, when the suction cup conveyor belt is in operation, the front side of the first backing wheel protrudes from the conveying surface of the suction cup conveyor belt to provide support.

[0016] In one example, the first conveying mechanism includes a first conveyor belt, and a plurality of second backrest wheels are provided above the rear side of the first conveyor belt and below the air guide plate. The front side of the second backrest wheels protrudes forward from the front side of the air guide plate. A plurality of third backrest wheels are provided above the front side of the first conveyor belt. The third backrest wheels are moved back and forth by a front push plate cylinder, thereby achieving the front and rear limit of the lower part of the glass and the guiding function along the conveying direction.

[0017] In one example, the glue dispensing section further includes a glue dispensing mechanism and a glue supply mechanism. The glue supply mechanism includes a base, on which two glue supply units with the same glue supply speed are provided. Each glue supply unit includes a glue barrel detachably connected to the base. Each glue barrel is equipped with a glue supply pressure plate and a glue pump. The glue supply pressure plate and the glue pump can be driven to rise and fall by a third driving component. In the two glue supply units, the glue outlet of the glue pump of one glue supply unit is connected to the glue dispensing mechanism through a first glue supply pipe, and the glue supply pressure plate of this glue supply unit is provided with a glue inlet. The glue outlet of the glue pump of the other glue supply unit is connected to the glue inlet through a second glue supply pipe, so as to realize the glue supply of the two glue barrels in series.

[0018] In one example, the glue bucket is fixed to the base by a positioning assembly, which includes a first glue bucket clamping housing and a second glue bucket clamping housing. One side of the first glue bucket clamping housing and the second glue bucket clamping housing are connected by a welded hinge, and the other side is connected by a latch-type quick clamp to facilitate clamping and releasing the glue bucket. The outer side of the first glue bucket clamping housing or the outer side of the second glue bucket clamping housing is fixed to the base by multiple clamping ribs.

[0019] In one example, the glue supply platen is also provided with a vent hole and a glue tank venting mechanism that cooperates with the vent hole. The glue tank venting mechanism includes a first cylinder that is inverted and mounted on the top of the glue supply platen via a first bracket. The lower end of the piston rod of the first cylinder is connected to an venting rod, which can drive the venting rod to cooperate with the vent hole to expose or close the vent hole. Specifically, the first bracket includes a base plate, a top plate, and a fixing column connecting the two. The cylinder body of the first cylinder is fixed to the top plate, and the base plate is fixed to the glue supply platen outside the vent hole. The base plate is provided with a corresponding through-hole, and a groove is provided in the through-hole. A sealing ring is installed in the groove to seal with the venting rod.

[0020] In one example, a glue supply channel is formed between the glue supply platen and the glue pump outlet. An exhaust port is provided near the end of the glue supply channel. An exhaust channel exhaust mechanism is provided outside the exhaust port, which includes a fixed block fixed to the outside of the exhaust port. An exhaust channel connecting the glue supply channel to the outside is provided inside the fixed block. A valve column is installed in the exhaust channel. The valve column can be driven to rotate by a fourth driving member so that the exhaust port can be cut off or connected to the outside.

[0021] The fourth driving component includes a second cylinder and a lever arm. One end of the lever arm is fixed relative to the valve stem, and the other end is hinged to the output end of the second cylinder via a first hinge shaft. The cylinder body of the second cylinder is hinged to a mounting base fixed relative to the glue supply plate via a second hinge shaft. The first hinge shaft and the second hinge shaft are arranged in the same direction so that the valve stem can be rotated under the drive of the second cylinder.

[0022] Furthermore, the piston rod end of the second cylinder is connected to the first hinge shaft via a fisheye connector.

[0023] In one example, the heating section includes a heating frame. A feeding mechanism is located at the lower front of the heating frame. A glass detection switch is located near the end of the feeding mechanism. From bottom to top, a lower crossbeam, a middle crossbeam, and an upper crossbeam are sequentially arranged on the heating frame behind the feeding mechanism to support and guide the glass. A left vertical beam and a right vertical beam are located on the heating frame in front of the feeding mechanism. Vertical heating elements are respectively provided on the left and right vertical beams. A horizontal upper heating element is provided on the upper crossbeam. A horizontal lower heating element is located on the heating frame in front of the feeding mechanism, away from... The left vertical beam of the glass detection switch can move left and right through the fifth driving component. The heating frame is provided with vertical guide rails for the upper and middle crossbeams to slide up and down. The upper crossbeam can be driven to move up and down through the sixth driving component. The middle crossbeam can move with the upper crossbeam through several sets of transmission mechanisms. The transmission mechanism includes a transmission chain and a transmission gear. The transmission gear is fixed to the rear side of the middle crossbeam. One end of the transmission chain is fixed to the upper part of the heating frame, and the other end passes around the transmission gear and is fixed to the upper crossbeam, so that the moving distance of the middle crossbeam is half the moving distance of the upper crossbeam.

[0024] In one example, the upper crossbeam, middle crossbeam, and lower crossbeam are each provided with a plurality of fourth backrest wheels at intervals along the feeding direction.

[0025] In one example, the rear side of the heating frame is provided with a protective plate.

[0026] The present invention employs the above-described structure and has the following advantages:

[0027] 1. The first four sections of the sealant application production line are set up with a conveyor frame, air guide plate, air supply pipe, etc., in conjunction with the first or second conveyor mechanism. This enables the glass to move by air flotation. The non-contact support movement of the upper part of the glass effectively avoids the problem of large-area adhesion caused by roller support. This ensures the cleanliness of the insulating glass production without the need for special cleaning in the later stages. In particular, the air gaps are set from back to front and tilted upwards. This angle makes it easier to control the glass to be transported safely and stably. Moreover, the use of fewer rows of air gaps can achieve a larger blowing area to accommodate glass of different sizes. In addition, the fewer rows of air gaps and the greater spacing make it less likely for adjacent air gaps to interfere with each other, which is conducive to stable glass transport. However, this air gap setting will give the glass an upward thrust. The reduced friction between the glass and the conveyor belt can easily lead to slippage, which will affect the accuracy of sealant application. Based on this, this application can effectively stabilize the glass and avoid slippage by using a synchronous conveyor belt mechanism, a suction cup conveyor belt mechanism, and a first backing wheel. This will facilitate the accurate application of sealant to the glass.

[0028] 2. For the heating section of the glue application production line, it is necessary not only to avoid or reduce the adhesion of the glue, but also to consider the support and heating of the glass (because the glass is easy to soften when heated). This application uses the middle crossbeam, upper crossbeam, sixth drive component and transmission mechanism to provide stable support and targeted heating for glass of different sizes through the cooperation of the left vertical beam, fifth drive component and other structures. The overall structure of the heating section is reasonably arranged, the adjustment steps are simple and the adjustment speed is fast. At the same time, the contact area between the glass and the roller is also small, and subsequent cleaning is basically unnecessary.

[0029] 3. In the glue supply mechanism, connecting two glue buckets in series increases the continuous glue supply time. Specifically, the glue bucket directly connected to the dispensing mechanism only consumes its spacer glue when the other bucket is replaced. Therefore, the time it takes to consume one bucket is several times the bucket replacement time, allowing n+1 buckets to be replaced without affecting the glue supply. Since each bucket replacement takes 30-40 minutes or more, the series connection significantly improves production efficiency. The use of a first bucket clamping shell, a second bucket clamping shell, a latch-type quick clamp, and welded hinges to limit the glue bucket movement results in faster replacement speeds, further extending the continuous glue supply time.

[0030] 4. In the glue supply mechanism, the automated glue tank venting mechanism and flow channel venting mechanism can fully exhaust air before glue application, and the venting is quick and convenient, ensuring the continuity of glue application and thus helping to ensure the quality of glue application.

[0051] Sealing Process: During the sealing process, the glass undergoes a U-shaped sealing step. Specifically, the glass is conveyed from the front conveyor section through the sealing section to the rear conveyor section. As the glass is conveyed, the sealing section applies sealant to the lower edge of the glass (or first the upper edge). After the lower edge is sealed, the glass stops moving, and then the left edge is sealed. After the upper edge is sealed, the glass is conveyed from the rear conveyor section through the sealing section to the front conveyor section. During this conveying process, the sealing section applies sealant to the upper edge. When the upper edge is sealed, the glass stops conveying, and then the right edge is sealed, thus completing one glass sealing process. The glass is then conveyed to the trimming section for subsequent repairs. The automatic sealing production line of this application will be explained below through some embodiments.

[0052] like Figure 1-5As shown in this embodiment, the automatic glue-applying production line for TPSS thermoplastic warm edge spacer strips for insulated glass in doors and windows includes a front conveying section a, a glue-applying section b, a rear conveying section c, a trimming section d, and a heating section e arranged sequentially along the production direction. Each of the front conveying section a, glue-applying section b, rear conveying section c, and trimming section d includes a conveyor frame a1. A guide plate a2 is obliquely fixed to the front side of the conveyor frame a1. The guide plate a2 has multiple rows of air slits a21 spaced from top to bottom, running through its front and rear. These air slits a21 are obliquely upwards from back to front; in practical applications, two rows of air slits are sufficient. A supply pipe a3 is provided on the rear side of the guide plate a2 corresponding to the air slits, and the supply pipe a3 is connected to an air flotation fan a4. Below the guide plates of the front conveying section a, rear conveying section c, and trimming section d... Each component is equipped with a first conveying mechanism a5 for conveying glass G. Below the air guide plate of the glue application section b, there is a second conveying mechanism b1 for conveying glass. The second conveying mechanism b1 includes a conveying beam b11 fixed to the conveyor frame. Two synchronous conveyor belt mechanisms b12 are provided on the front side of the conveying beam b11 along the conveying direction. A glue nozzle scraping device b2 is installed between the two synchronous belt conveyor mechanisms b12. A suction cup conveyor belt mechanism b13 is provided on the top of the conveying beam b11. The conveying surface of the suction cup conveyor belt mechanism b13 faces forward, and the conveying surface of the synchronous belt conveyor mechanism b12 faces upward. Several first backrest wheels b14 are also provided on the conveying beam b11 below the suction cup conveyor belt mechanism b13 to support the glass, so as to prevent the glass from sticking to the conveying surface of the suction cup conveyor belt mechanism.

[0053] In practical applications, a trimming machine d1 will be set in front of the conveyor frame of the trimming section d according to the trimming needs. Since the trimming machine is a relatively mature technology, it can be directly adopted from the market. Therefore, the trimming machine will not be elaborated on here.

[0054] Working Principle: When conveying glass through the above structure, glass G is conveyed by the first conveying mechanism a5. Stable glass conveying is achieved by providing air flotation support to the upper part of the glass, avoiding large-area adhesion. The air slits a21 are angled upwards from back to front, which not only makes it easy to control the glass tilt angle but also allows for a larger blowing area with fewer rows of air slits, thus accommodating glass of different sizes. The fewer rows of air slits and the greater spacing between them minimize interference between adjacent slits, further facilitating stable glass conveying. However, this air slit configuration provides an upward thrust to the glass during air blowing, reducing friction between the glass and the conveyor belt and making slippage more likely, thus affecting the accuracy of the sealant application. Therefore, a second conveying mechanism b1 is used in the sealant application section to ensure stable glass conveying without slippage, guaranteeing accurate sealant application.

[0055] In a specific example, such as Figure 4-5As shown, the suction cup conveyor belt mechanism b13 includes a suction cup conveyor belt b131, which is driven by a first driving member b132 and supported and tensioned by a first tensioning support member b133 located on the rear side of its conveying surface. The suction cup conveyor belt b131 is evacuated by an adsorption fan b134. The synchronous conveyor belt mechanism b12 includes a synchronous conveyor belt b121, which is driven by a second driving member b122 and supported and tensioned by a second tensioning support member b123 located below its conveying surface.

[0056] To ensure accurate synchronization, the two drive wheels of the two second drive components are connected by a belt, and one of the drive wheels is connected to a servo motor. The first tensioning support b133 includes a first support beam b1331 fixed to the top of the conveyor beam. A first guide plate b1332 is fixed to the front of the first support beam b1331 to limit the upper and lower sides of the suction cup conveyor belt b131. The second tensioning support b123 includes a second support beam b1231 fixed to the front of the conveyor beam b11. A second guide plate b1232 is fixed to the top of the second support beam b1231 to limit the front and rear sides of the synchronous conveyor belt b123. This configuration ensures the conveyor belt remains stable and does not sway.

[0057] In a specific example, the installation of the first backrest wheel b14 can be achieved using either a standard wheel mount or, for ease of adjustment, a variable mounting base b15. Specifically, the variable mounting base b15 includes an L-shaped fixing plate. The wheel mount for the first backrest wheel b14 is connected to the outer side of the vertical plate of the L-shaped fixing plate. A strip-shaped adjustment hole is provided on the horizontal plate of the L-shaped fixing plate, with the length of the hole aligned with the adjustment direction. The L-shaped fixing plate is fixed to the conveyor beam b11 by bolts that mate with the strip-shaped adjustment hole. During adjustment, after loosening the bolts, the position of the first backrest wheel can be adjusted by moving the variable mounting base; after adjustment, the bolts can be tightened.

[0058] Furthermore, when the suction cup conveyor belt b131 is in operation, the front side of the first backing wheel b14 protrudes from the conveying surface of the suction cup conveyor belt b131 to provide support.

[0059] In a specific example, such as Figure 6-7 As shown, the first conveying mechanism a5 can specifically adopt the following structure, which includes a first conveyor belt a51. Several second backrest wheels a52 are provided on the rear side above the first conveyor belt a51 and below the air guide plate. The front side of the second backrest wheels a52 protrudes from the front side of the air guide plate to support the glass. Several third backrest wheels a53 are provided on the front side above the first conveyor belt a51. The third backrest wheels a53 are moved back and forth by the front push plate cylinder a54, thereby realizing the front and rear limit of the lower part of the glass and the guiding function along the conveying direction.

[0060] In a specific example, such as Figure 1 , Figure 8-9 As shown, the glue dispensing section b further includes a glue dispensing mechanism b3 and a glue supply mechanism b4. The glue supply mechanism b4 includes a base b41, on which two glue supply units with the same glue supply speed are provided. Each glue supply unit includes a glue tank b42 detachably connected to the base. Each glue tank b42 is equipped with a glue supply pressure plate b43 and a glue pump b44. The glue pump can specifically be a gear pump. The glue supply pressure plate b43 and the glue pump b44 can be driven to rise and fall by a third drive component b45. In the two glue supply units, the glue outlet of the glue pump of one glue supply unit is connected to the glue dispensing mechanism b3 through a first glue supply pipe, and the glue supply pressure plate of this glue supply unit is provided with a glue inlet. The glue outlet of the glue pump of the other glue supply unit is connected to the glue inlet through a second glue supply pipe b46, so as to realize the glue supply of the two glue tanks in series. Regarding the glue dispensing mechanism, existing ones can be directly used, and will not be described in detail here.

[0061] In the above glue supply mechanism, by connecting two glue tanks b42 in series, the continuous glue supply time can be increased. Specifically, the glue tank directly connected to the glue dispensing mechanism b3 will only consume the spacer glue inside when the other glue tank is replaced. Therefore, when the time taken to consume one glue tank is a certain multiple of the glue tank replacement time, that many glue tanks can be replaced without affecting the glue supply. Since each glue tank replacement takes thirty to forty minutes or more (including disassembly, installation, venting operations, etc.), the above series connection of two glue tanks can significantly improve production efficiency and reduce the number of downtimes.

[0062] Regarding the third drive component b45, an existing dual-cylinder drive structure can be adopted. Specifically, a hydraulic cylinder is set on each side of the glue tank, and a bracket is connected between the output ends of the two hydraulic cylinders so that the glue pressure plate b43 and the glue pump b44 can be fixed to the bracket and move up and down with the hydraulic cylinders.

[0063] Furthermore, such as Figure 8 As shown, in order to minimize the replacement time of the glue bucket, the following glue bucket fixing method can be adopted. Specifically, the glue bucket b42 is fixed to the base b41 by a positioning component b47. The positioning component b47 includes a first glue bucket clamping shell b471 and a second glue bucket clamping shell b472. One side of the first glue bucket clamping shell b471 and the second glue bucket clamping shell b472 are connected by a welded hinge b473, and the other side is connected by a latch-type quick clamp b474 to facilitate clamping and releasing the glue bucket. The outer side of the first glue bucket clamping shell b471 or the outer side of the second glue bucket clamping shell b472 is fixed to the base b41 by multiple clamping ribs b475.

[0064] In a specific example, venting is required when initially applying glue to a new glue container; otherwise, the glue supply continuity will be affected, potentially leading to air leakage and poor sealing of the insulated glass. In addition to venting the glue container, the glue flow channel formed between the glue supply pressure plate and the glue pump outlet also needs to be vented.

[0065] To achieve automatic venting of the glue tank b42, the following structure can be adopted: (e.g.) Figure 10 As shown, specifically, the glue supply plate b43 is provided with an exhaust hole and a glue tank exhaust mechanism b48 that cooperates with the exhaust hole. The glue tank exhaust mechanism b48 includes a first bracket b481 that is inverted and installed on the glue supply plate. Figure 10 As shown, the first cylinder b482 is located at the top of the glue supply plate b43. The lower end of the piston rod of the first cylinder b482 is connected to an exhaust rod b483, which drives the exhaust rod b483 to engage with the exhaust port, exposing or sealing the exhaust port. The first support specifically includes a base plate, a top plate, and a fixing column connecting the two. The cylinder body of the first cylinder b482 is fixed to the top plate, and the base plate is fixed to the glue supply plate b43 outside the exhaust port. The base plate has a corresponding through-hole with a groove inside, and a sealing ring is installed in the groove to seal with the exhaust rod b483.

[0066] To achieve automatic venting of the adhesive supply channel, the following structure can be adopted: (e.g.) Figure 11 As shown, an exhaust port is provided near the end of the glue supply channel. An exhaust mechanism b49, which cooperates with the exhaust port, is provided outside the exhaust port. The mechanism includes a fixing block b491 fixed to the outside of the exhaust port. An exhaust channel b492, connecting the glue supply channel to the outside, is provided within the fixing block b491. A valve stem b493 is installed within the exhaust channel b492. The valve stem b493 can be driven to rotate by a fourth driving member, so that the exhaust port can be disconnected from or connected to the outside. The fourth driving member includes... The second cylinder b494 and the lever b495 are connected as follows: one end of the lever b495 is fixed relative to the valve stem b493, and the other end is hinged to the output end of the second cylinder b494 via a first hinge pin b496. The cylinder body of the second cylinder b494 is hinged to a mounting base b498 fixed relative to the glue supply plate b43 via a second hinge pin b497. The first hinge pin b496 and the second hinge pin b497 are arranged in the same direction to allow the valve stem b493 to rotate under the drive of the second cylinder b494. The piston rod end of the second cylinder is connected to the first hinge pin via a fisheye connector b499. Exhausting air from the glue supply channel prevents damage to the glue pump from high-speed dry running. In actual venting, the glue pump first rotates at low speed to vent air, and then rotates at high speed to deliver glue.

[0067] In a specific example, since glass softens when heated, the heating section is designed with the following structure in mind, considering factors such as glass support, applicability to different glass sizes, glass printing area, structural layout rationality, and simplicity: (e.g., ...) Figure 12-15 As shown, specifically, the heating section e includes a heating frame e1. A feeding mechanism e2 is located at the lower front of the heating frame e1. A glass detection switch e3 is located near the end of the feeding mechanism e2 to detect whether the glass is in place; this switch can be a diffuse reflection photoelectric sensor. From bottom to top, the heating frame e1 behind the feeding mechanism e2 has a lower crossbeam e4, a middle crossbeam e5, and an upper crossbeam e6 that support and guide the glass. The heating frame e1 in front of the feeding mechanism e2 has a left vertical beam e7 and a right vertical beam e8. Vertical heating elements are respectively provided on the left and right vertical beams e7 and e8 to heat the spacers on the left and right edges of the glass. A horizontal upper heating element e9 is provided on the upper crossbeam e6 to heat the spacers on the upper edge of the glass. A horizontal lower heating element is located in front of the feeding mechanism e2 on the heating frame e1 to heat the spacers on the lower edge of the glass. The left vertical beam e7, away from the glass detection switch e3, can be... The fifth driving component e10 enables its left and right movement. The heating frame e1 is equipped with vertical guide rails e11 for the upper crossbeam e6 and the middle crossbeam e5 to slide up and down. The upper crossbeam e6 can be driven up and down by the sixth driving component e12. The middle crossbeam e5 can move with the upper crossbeam e6 through several sets of transmission mechanisms e13. Each transmission mechanism e13 includes a transmission chain e131 and a transmission gear e132. The transmission gear e132 is fixed to the rear side of the middle crossbeam e5. One end of the transmission chain e131 is fixed to the upper part of the heating frame e1, and the other end passes around the transmission gear e132 and is fixed to the upper crossbeam e6, so that the moving distance of the middle crossbeam e5 is half the moving distance of the upper crossbeam e6. The feeding mechanism can be referenced from the first conveying mechanism.

[0068] Furthermore, multiple fourth backrest wheels e14 are sequentially spaced along the feeding direction on the upper crossbeam e6, middle crossbeam e5, and lower crossbeam e4 to provide support and guidance. A forward-extending heating element cover e15 is connected above the fourth backrest wheels e14 on the upper crossbeam e6. A transversely positioned heating element e9 is located inside the heating element cover e15 in front of the glass. This arrangement allows for direct heating of the spacer strip in front of the glass, resulting in faster heating.

[0069] Furthermore, the rear side of the heating frame e1 is provided with a protective plate e18, which not only prevents dust but also helps to keep the heat.

[0070] Heating Section Working Process 1: After determining the glass size, heating section e begins adaptive adjustment. Specifically, the sixth drive component slides the upper crossbeam along the vertical guide rail. Under the action of the transmission mechanism, the middle crossbeam slides along the vertical guide rail until it reaches the appropriate position. The middle crossbeam's movement distance is half that of the upper crossbeam, ensuring that the middle crossbeam remains between the upper and lower crossbeams, effectively supporting the upper, middle, and lower parts of the glass. The upper and middle crossbeams are linked, allowing for a reasonable and simple arrangement of the structures without affecting the support function. During this process, the fifth drive component also moves the left vertical beam until it reaches the appropriate position. The upper crossbeam has a horizontal upper heating element, the lower crossbeam has a horizontal lower heating element near the lower crossbeam, and the left and right vertical beams have vertical heating elements. After the glass is delivered, the heating elements in all four directions can cover and heat the spacers along the glass edges. Electric heating elements can be used for these heating elements.

[0071] Heating section operation process 2: The glass is conveyed to the heating device. When the glass detection switch detects the glass, the glass will stop at that position for heating. After heating is completed, it can be conveyed to the next process.
