Description

A film fixing device for photovoltaic module processing

Technical Field

The invention relates to the technical field of adhesive film laying, and in particular to an adhesive film fixing device used for photovoltaic module processing.

Background technique

Laying adhesive film for double-glass modules is an important process of photovoltaic modules. Currently, there are three methods for laying adhesive film in the industry: direct laying, middle spot welding laying, and two-end spot welding laying. Although direct laying does not damage the adhesive film, it is easy to cause the adhesive film to shift on the glass surface; middle spot welding and two-end spot welding laying will damage the adhesive film so as to fix the adhesive film on the glass surface. Therefore, a film fixing device for photovoltaic module processing is proposed, which uses infrared heating technology to fix the position of the adhesive film so that the laid film can be well adsorbed on the glass surface without causing shifting or bulging.

Summary of the invention

In view of the problems in the prior art, the present invention provides a film fixing device for photovoltaic module processing, so that the laid film can be well adsorbed on the glass surface without causing deviation or bulging.

The technical solution adopted by the present invention to solve its technical problem is a film fixing device for photovoltaic module processing, comprising a fixing frame, a conveyor belt for conveying glass and film is provided above the fixing frame, the film is laid on the upper surface of the glass, the conveyor belt is driven by a conveyor roller, a support frame fixedly installed on the fixing frame is provided below the conveyor belt, a plurality of groups of electric hydraulic telescopic rods are provided above the support frame, the output ends of the plurality of groups of the electric hydraulic telescopic rods are fixedly connected to a support plate, an infrared heater is provided on the upper part of the support plate, and the infrared heater is used to heat the film.

By adopting the above technical solution, the glass is transported by the conveyor belt. After the glass is transported to a certain position, the infrared heater switch is started, and the infrared heater heats the film through the glass. The heating is stopped and the infrared heater is automatically turned off at the set temperature and time. At this time, the heated film is not melted, and can be firmly adsorbed on the glass surface under natural cooling, playing the role of fixing the film, and the film is not damaged;

The height of the infrared heater can be adjusted by the electric hydraulic telescopic rod, so that the height of the infrared heater can be adjusted according to the actual use situation;

Compared with traditional soldering iron spot welding and electronic spot welding, the present invention destroys the adhesive film under high temperature conditions and causes damage to the adhesive film; secondly, compared with traditional soldering iron spot welding and electronic spot welding, no spot welding smoke is generated; and compared with traditional soldering iron spot welding, no burns or scalds are caused to the operating staff; the present invention also does not affect the reliability of the components; and the deviation of the adhesive film when it flows on the assembly line can be reduced, thereby reducing the rework of the adhesive film.

Specifically, sliding support structures are connected to both sides of the fixed frame, and a preheating structure is slidably connected between the two groups of sliding support structures. The sliding support structures include a first fixed block and a second fixed block. A horizontally arranged moving rod is provided between the first fixed block and the second fixed block. The moving rod is magnetic-friendly. A preheating structure is slidably connected between the two groups of moving rods. The preheating structure is located above the conveyor belt. The first fixed block and the second fixed block are fixedly connected to the outer side of the fixed frame through a connecting rod. Extrusion rods are evenly distributed on the outer surface of the conveyor belt, and an inclined surface is provided at the upper end of the extrusion rod.

By adopting the above technical solution, the adhesive film is laid on the upper surface of the glass, and the conveyor belt drives the glass to move when it rotates. After the conveyor belt rotates to a certain position, the extrusion rod installed on the conveyor belt squeezes the structure on one side of the preheating structure and drives the preheating structure to move. At this time, the preheating structure is located above the glass. The adhesive film laid on the upper surface of the glass is preheated in advance by relying on the preheating structure, which is convenient for subsequent infrared heaters to heat it, thereby improving processing efficiency.

When the extrusion rod drives the preheating structure to move, the moving rod facilitates the preheating structure to slide between the first fixed block and the second fixed block; when the preheating structure is squeezed and contacted with one side of the second fixed block through the moving rod, the preheating of the film is completed.

Specifically, the preheating structure includes a blowing plate, a cavity is provided inside the blowing plate, a heating wire is provided in the cavity, a plurality of groups of air outlet holes are provided on the lower surface of the blowing plate, the air outlet holes face the conveyor belt, sliding grooves are provided through both ends of the blowing plate, the moving rod passes through the sliding groove and is slidably connected to the sliding groove, an air inlet joint is provided on one side of the blowing plate, and the air inlet joint is communicated with the inside of the cavity;

A reset movement structure is arranged in the sliding groove, and the reset movement structure facilitates driving the blowing plate to reset and move. A driving structure is arranged on the outer side of the blowing plate, and the driving structure is used to drive the blowing plate to reset and move.

By adopting the above technical solution, the air inlet joint is connected to the air source; after the conveyor belt rotates to a certain position, the blowing plate is located above a group of glass, and the extrusion rod is pressed and contacted with one side of the blowing plate, and the blowing plate is driven to slide on the moving rod, and the movement stability and convenience of the blowing plate can be improved by the action of the sliding groove;

When the blowing plate moves, the gas enters the cavity through the air inlet joint, and heats the inside of the cavity by the heating wire. The gas is finally discharged through the air outlet and blown to the upper surface of a group of glass, preheating the film laid on the upper surface of the glass, making it easier for the subsequent infrared heater to heat it and improve the processing efficiency; and, by blowing air vertically to the film through the air outlet, the stability of the film laid on the glass can be improved, avoiding the misalignment when the glass and the film move synchronously, thereby further ensuring the effect of film fixation;

When the blowing plate moves to a certain position, one side of the blowing plate is squeezed and contacted with the second fixed block, and the second fixed block prevents the blowing plate from moving further. At the same time, the blowing plate is squeezed by the inclined surface on the upper end of the squeezing rod, so that the blowing plate moves upward. After the blowing plate moves up, the reset moving structure in the sliding groove makes it convenient for the driving structure to drive the blowing plate to reset, and facilitates the preheating of the next group of adhesive films, thereby improving ease of use and production efficiency.

Specifically, the reset moving structure includes two groups of first slots and second slots arranged in the sliding slot, the two groups of the first slots are located above the inner wall of the sliding slot, a first magnetic roller is rotatably connected in the first slot, the first magnetic roller is magnetically adsorbed to the upper surface of the moving rod, the moving rod is rollingly connected to the first magnetic roller, a press switch is provided on the upper part of the inner wall of the sliding slot, the press switch is used to control the operation of the heating wire and the air intake joint, and in the initial state, the upper surface of the moving rod is squeezed and contacted with the press switch to turn on the air intake of the heating wire and the air intake joint;

The two groups of the second slots are located below the inner wall of the sliding slot. A second magnetic roller is rotatably connected in the second slot. The second magnetic roller is magnetically adsorbed to the lower surface of the moving rod. The moving rod is rollingly connected to the second magnetic roller. An inclined extrusion plate is provided above the first fixed block.

By adopting the above technical scheme, after the driving structure drives the blowing plate to reset, the blowing plate is squeezed by the squeezing plate to drive the blowing plate to move down again. When the blowing plate moves down, the lower surface of the moving rod is separated from the second magnetic roller, and the upper surface of the moving rod is magnetically adsorbed to the first magnetic roller. When the moving rod is magnetically adsorbed to the first magnetic roller, the blowing plate returns to its initial state, and the upper surface of the moving rod is squeezed and contacted with the push switch, and the air intake of the heating wire and the air intake joint is turned on. Subsequently, the blowing plate is driven to move by the squeezing rod on the conveyor belt again. When the blowing plate moves, the first magnetic roller rolls and contacts with the upper surface of the moving rod, and improves the movement stability of the blowing plate, and at the same time, the adhesive film is preheated by the synchronous movement of the blowing plate and the glass.

When the blowing plate moves to a certain position, one side of the blowing plate is pressed and contacted with the second fixed block, and the blowing plate is pressed by the pressing rod to move the blowing plate upward. When the blowing plate moves upward, the moving rod is separated from the first magnetic roller and no longer presses the pressing switch. At this time, the heating wire and the air inlet joint are turned off, which can effectively reduce energy consumption.

When the blowing plate moves up, the moving rod is magnetically attracted to the second magnetic roller in the second slot, and the driving structure drives the blowing plate to reset and move. After the blowing plate is reset and moved to a certain position, the blowing plate is squeezed by the squeezing plate to move the blowing plate downward. After the blowing plate moves downward, the moving rod is separated from the second magnetic roller and magnetically attracted to the first magnetic roller in the first slot. At the same time, the pressing switch is squeezed to turn on the air intake of the heating wire and the air intake joint. At this time, the next group of adhesive films can be preheated again.

It should be pointed out that the blowing plate of the present invention is in compression contact with one side of the first fixing block in an initial state.

Specifically, the driving structure includes two groups of gas springs, the fixed ends of the two groups of gas springs are fixedly connected to the outer side of the fixed frame through fixed rods, the output ends of the two groups of gas springs are fixedly connected to skateboards, and two groups of support wheels corresponding to the skateboards are provided on the side of the blowing plate close to the second fixed block, and the support wheels are in extrusion contact with one side of the skateboard.

By adopting the above technical scheme, when the extrusion rod on the conveyor belt moves with the blowing plate, the supporting wheel provided on one side of the blowing plate is in squeezing contact with the slide plate and squeezes the slide plate. When the slide plate is squeezed, the gas spring is driven to squeeze and accumulate force. When the blowing plate moves to the limit, the blowing plate is driven to move up by relying on the extrusion rod. When the blowing plate moves up, it relies on the supporting wheel to squeeze and contact with one side of the slide plate, thereby improving the upward stability of the blowing plate. When the blowing plate is completed to move up, the extrusion rod no longer squeezes the blowing plate, and at the same time relies on the reset effect of the gas spring to drive the slide plate to reset and move. When the slide plate moves, it squeezes the supporting wheel, thereby driving the blowing plate to reset and move. When the blowing plate is reset to a certain position, the extrusion plate provided on the first fixed block is used to squeeze the blowing plate, so that the blowing plate moves down, and it is convenient to preheat the next group of adhesive films, thereby completing the reciprocating movement effect of the blowing plate.

Specifically, several groups of air outlet holes include a first air outlet hole and a second air outlet hole, an adjustable blowing structure is provided in the blowing plate, the adjustable blowing structure includes an adjustment plate arranged inside the blowing plate, the adjustment plate is located below the heating wire, the adjustment plate is slidably connected to the lower surface of the inner wall of the cavity, a first through hole and a second through hole are provided on the adjustment plate, and in the initial state of the adjustment plate, the first through hole corresponds to the first air outlet hole, and the second through hole is staggered with the second air outlet hole.

By adopting the above technical solution, when the blowing plate and the glass move synchronously, the adhesive film laid on the upper surface of the glass is preheated, and the preheating position of the adhesive film can be adjusted by the adjustment plate; when the blowing plate moves, the first through hole on the adjustment plate corresponds to the first air outlet, so that the gas passes through the first through hole and the first air outlet to preheat the designated area of the adhesive film, further improving the preheating effect, and because the second through hole and the second air outlet are staggered, the gas will not be discharged through the second air outlet;

After the adjustment plate moves, the first through hole intersects with the first air outlet, thereby closing the air outlet of the first air outlet. As the adjustment plate moves, the second through hole corresponds to the second air outlet, and the gas is discharged through the second air outlet, thereby preheating the designated area on the other side of the film, improving the preheating effect, and facilitating preheating the designated area of the film according to actual use conditions.

It should be pointed out that the adjustment plate described in the present invention needs to be used in conjunction with two groups of infrared heaters when in use; when preheating of one group of designated areas is completed, one group of infrared heaters is used to heat the adhesive film in the designated area, and at the same time, the preheating work of another group of designated areas is also switched. After preheating of the other group of designated areas is completed, another group of infrared heaters is used to heat the designated areas of the adhesive film, thereby improving convenience of use.

Specifically, a connecting groove is provided inside the blowing plate, one end of the connecting groove is connected to the cavity, and the other end of the connecting groove is connected to a group of sliding grooves. The upper surface of the adjusting plate is fixedly connected to one end of the sliding rod, and a trapezoidal groove is provided on the side of the moving rod away from the gas spring, and the trapezoidal groove is located on the side of the moving rod close to the first fixed block, and one end of the sliding rod away from the adjusting plate passes through the connecting groove and is slidably connected to the trapezoidal groove, and one end of the sliding rod away from the adjusting plate is provided with a guide slope inclined downward, one end of the return spring is fixedly connected to the connecting groove, and the other end of the return spring is fixedly connected to the outer side of the sliding rod.

By adopting the above technical solution, when the blowing plate moves, one end of the sliding rod passes through the connecting groove and is slidably connected with the trapezoidal groove of the moving rod, and at this time the first through hole corresponds to the first air outlet; when the blowing plate moves to the middle of the moving rod, at this time one end of the sliding rod is pressed and contacted with one side of the trapezoidal groove, and the sliding rod is pressed to move the sliding rod in the connecting groove, and the reset spring is pressed when the sliding rod moves, and at the same time the adjustment plate is driven to move, and after the adjustment plate moves, the first through hole is staggered with the first air outlet, and the second through hole corresponds to the second air outlet, so as to switch the heating area of the film;

When the blowing plate moves to a certain position, the extrusion rod on the conveyor belt drives the blowing plate to move up, and the sliding rod relies on the reset effect of the reset spring to restore the sliding rod to the initial state. At this time, the sliding rod is located above the moving rod;

When the blowing plate is reset, the extrusion plate on the first fixed block is used to squeeze the blowing plate downward. When the blowing plate moves downward, the upper surface of the moving rod is used to squeeze the inclined surface of the sliding rod, so that the sliding rod enters the connecting groove again, and the reset spring is squeezed and accumulated. When the blowing plate moves down to the initial state, the reset effect of the reset spring drives the sliding rod to reset. At this time, the sliding rod is reset and moved to the trapezoidal groove of the moving rod, thereby restoring the adjustment plate to its initial state. At this time, the next group of adhesive films can be preheated, further improving the convenience of use.

The adhesive film is laid on the upper surface of the glass, and the conveyor belt 2 is driven by a conveyor roller. A support frame 3 fixedly installed on the fixing frame 1 is provided below the conveyor belt 2, and a plurality of groups of electric hydraulic telescopic rods 4 are provided above the support frame 3. The output ends of the plurality of groups of the electric hydraulic telescopic rods 4 are fixedly connected to a support plate 5. An infrared heater 6 is provided on the upper part of the support plate 5, and the infrared heater 6 is used to heat the adhesive film.

When in use, the glass is transported by the conveyor belt 2. After the glass is transported to a certain position, the infrared heater 6 is turned on. The infrared heater 6 heats the adhesive film through the glass. The heating stops at the set temperature and time and the infrared heater 6 is automatically turned off. At this time, the heated adhesive film is not melted. Under the condition of natural cooling, it can be firmly adsorbed on the glass surface to fix the adhesive film without being damaged.

The height of the infrared heater 6 can be adjusted by the electric hydraulic telescopic rod 4, so as to facilitate the height adjustment of the infrared heater 6 according to the actual use situation;

Compared with traditional soldering iron spot welding and electronic spot welding, the present invention destroys the adhesive film under high temperature conditions and causes damage to the adhesive film; secondly, compared with traditional soldering iron spot welding and electronic spot welding, no spot welding smoke is generated; and compared with traditional soldering iron spot welding, no burns or scalds are caused to the operating staff; the present invention also does not affect the reliability of the components; and the deviation of the adhesive film when it flows on the assembly line can be reduced, thereby reducing the rework of the adhesive film.

In order to facilitate the preheating of the adhesive film, exemplarily, as shown in Figures 2, 3 and 4, the present invention also includes that sliding support structures are connected to both sides of the fixed frame 1, and a preheating structure is slidably connected between the two groups of sliding support structures. The sliding support structures include a first fixed block 7 and a second fixed block 8, and a horizontally arranged moving rod 9 is provided between the first fixed block 7 and the second fixed block 8. The moving rod 9 is magnetic-friendly, and a preheating structure is slidably connected between the two groups of the moving rods 9. The preheating structure is located above the conveyor belt 2, and the first fixed block 7 and the second fixed block 8 are fixedly connected to the outer side of the fixed frame 1 through a connecting rod, and extrusion rods 10 are evenly distributed on the outer surface of the conveyor belt 2, and the upper end of the extrusion rod 10 is provided with an inclined surface.

When in use, the adhesive film is laid on the upper surface of the glass, and the conveyor belt 2 drives the glass to move when it rotates. After the conveyor belt 2 rotates to a certain position, the extrusion rod 10 installed on the conveyor belt 2 squeezes the structure on one side of the preheating structure and drives the preheating structure to move. At this time, the preheating structure is located above the glass. The adhesive film laid on the upper surface of the glass is preheated in advance by relying on the preheating structure, which is convenient for the subsequent infrared heater 6 to heat it, thereby improving the processing efficiency;

When the extrusion rod 10 drives the preheating structure to move, the moving rod 9 facilitates the preheating structure to slide between the first fixed block 7 and the second fixed block 8; when the preheating structure is squeezed and contacted with one side of the second fixed block 8 through the moving rod 9, the preheating of the film is completed.

In order to further ensure the effect of fixing the adhesive film, exemplarily, as shown in Figures 2, 3, 7 and 10, the present invention also includes that the preheating structure includes a blowing plate 11, a cavity is provided inside the blowing plate 11, a heating wire 12 is provided in the cavity, a plurality of groups of air outlet holes 13 are provided on the lower surface of the blowing plate 11, the air outlet holes 13 face the conveyor belt 2, sliding grooves 14 are provided through both ends of the blowing plate 11, the moving rod 9 passes through the sliding groove 14 and is slidably connected to the sliding groove 14, an air inlet joint 15 is provided on one side of the blowing plate 11, and the air inlet joint 15 is communicated with the inside of the cavity;

When the blowing plate 11 moves, the gas enters the cavity through the air inlet joint 15, and heats the inside of the cavity by relying on the heating wire 12. The gas is finally discharged through the air outlet 13 and blown to the upper surface of a group of glass, preheating the adhesive film laid on the upper surface of the glass, which is convenient for the subsequent infrared heater 6 to heat it, thereby improving the processing efficiency; and, by relying on the air outlet 13 to blow air vertically to the adhesive film, the stability of the adhesive film laid on the glass can also be improved, and the misalignment of the glass and the adhesive film when they move synchronously can be avoided, thereby further ensuring the effect of fixing the adhesive film;

When the blowing plate 11 moves to a certain position, one side of the blowing plate 11 is squeezed and contacted with the second fixed block 8, and the second fixed block 8 prevents the blowing plate 11 from moving further. At the same time, the blowing plate 11 is squeezed by the inclined surface at the upper end of the squeezing rod 10, so that the blowing plate 11 moves upward. After the blowing plate 11 moves upward, the resetting moving structure provided in the sliding groove 14 facilitates the driving structure to drive the blowing plate 11 to reset, and facilitates the preheating of the next group of adhesive films, thereby improving ease of use and production efficiency.

In order to further improve the movement stability and use convenience of the blowing plate 11, exemplarily, as shown in Figures 3, 6, 7, 8, 9 and 10, the present invention also includes that the reset movement structure includes two groups of first slots 16 and second slots 17 arranged in the sliding slot 14, the two groups of the first slots 16 are located above the inner wall of the sliding slot 14, a first magnetic roller 18 is rotatably connected in the first slot 16, the first magnetic roller 18 is magnetically adsorbed to the upper surface of the moving rod 9, the moving rod 9 is rollingly connected to the first magnetic roller 18, a press switch 19 is provided on the upper part of the inner wall of the sliding slot 14, the press switch 19 is used to control the operation of the heating wire 12 and the air intake joint 15, and in the initial state, the upper surface of the moving rod 9 is squeezed and contacted with the press switch 19 to turn on the air intake of the heating wire 12 and the air intake joint 15;

The two groups of the second slots 17 are located below the inner wall of the sliding slot 14. The second magnetic roller 20 is rotatably connected in the second slot 17. The second magnetic roller 20 is magnetically adsorbed to the lower surface of the moving rod 9. The moving rod 9 is rollingly connected to the second magnetic roller 20.

Subsequently, the blowing plate 11 is driven to move by the squeezing rod 10 on the conveyor belt 2 again; when the blowing plate 11 moves, the first magnetic roller 18 rolls and contacts with the upper surface of the moving rod 9, and improves the moving stability of the blowing plate 11, and at the same time relies on the synchronous movement of the blowing plate 11 and the glass to preheat the adhesive film;

When the blowing plate 11 moves to a certain position, one side of the blowing plate 11 is pressed and contacted with the second fixed block 8, and the blowing plate 11 is pressed by the pressing rod 10 to move the blowing plate 11 upward. When the blowing plate 11 moves upward, the moving rod 9 is separated from the first magnetic roller 18 and no longer presses the pressing switch 19. At this time, the heating wire 12 and the air inlet joint 15 are turned off, which can effectively reduce energy consumption.

When the blowing plate 11 moves upward, the moving rod 9 is magnetically attracted to the second magnetic roller 20 in the second slot 17, and the driving structure drives the blowing plate 11 to reset and move. After the blowing plate 11 resets and moves to a certain position, the squeezing plate 21 is used to squeeze the blowing plate 11 to move the blowing plate 11 downward. After the blowing plate 11 moves downward, the moving rod 9 is separated from the second magnetic roller 20, and is magnetically attracted to the first magnetic roller 18 in the first slot 16. At the same time, the pressing switch 19 is squeezed to turn on the air intake of the heating wire 12 and the air intake connector 15. At this time, the next group of adhesive films can be preheated again.

It should be pointed out that the blowing plate 11 of the present invention is in compression contact with one side of the first fixing block 7 in an initial state.

In order to facilitate the reset movement of the blowing plate 11, exemplarily, as shown in Figures 2, 3 and 4, the present invention also includes that the driving structure includes two groups of gas springs 22, and the fixed ends of the two groups of gas springs 22 are fixedly connected to the outer side of the fixed frame 1 through fixed rods, and the output ends of the two groups of gas springs 22 are fixedly connected to a slide plate 23, and the side of the blowing plate 11 close to the second fixed block 8 is provided with two groups of support wheels 24 corresponding to the slide plate 23, and the support wheels 24 are in extrusion contact with one side of the slide plate 23.

When the blowing plate 11 is reset to a certain position, the blowing plate 11 is squeezed by the squeezing plate 21 provided on the first fixed block 7, so that the blowing plate 11 moves downward, and it is convenient to preheat the next group of adhesive films, thereby completing the reciprocating movement effect of the blowing plate 11.

In order to facilitate preheating of the designated area of the film according to actual usage conditions, exemplarily, as shown in Figures 11, 12 and 13, the present invention also includes that several groups of air outlet holes 13 include a first air outlet hole 25 and a second air outlet hole 26, and an adjustable blowing structure is provided in the blowing plate 11, and the adjustable blowing structure includes an adjustment plate 27 arranged inside the blowing plate 11, and the adjustment plate 27 is located below the heating wire 12, and the adjustment plate 27 is slidably connected to the lower surface of the inner wall of the cavity, and the adjustment plate 27 is provided with a first through hole 28 and a second through hole 29 that are penetrated, and in the initial state of the adjustment plate 27, the first through hole 28 corresponds to the first air outlet hole 25, and the second through hole 29 is staggered with the second air outlet hole 26.

When in use, when the blowing plate 11 and the glass move synchronously, the adhesive film laid on the upper surface of the glass is preheated, and the preheating position of the adhesive film can be adjusted by the adjusting plate 27; when the blowing plate 11 moves, the first through hole 28 on the adjusting plate 27 corresponds to the first air outlet 25, so that the gas passes through the first through hole 28 and the first air outlet 25 to preheat the designated area of the adhesive film, further improving the preheating effect, and because the second through hole 29 is staggered with the second air outlet 26, the gas will not be discharged through the second air outlet 26;

After the adjustment plate 27 moves, the first through hole 28 intersects with the first air outlet 25, thereby closing the air outlet of the first air outlet 25, and as the adjustment plate 27 moves, the second through hole 29 corresponds to the second air outlet 26, and the gas is discharged through the second air outlet 26, thereby preheating the designated area on the other side of the film, improving the preheating effect, and facilitating the preheating of the designated area of the film according to actual use conditions;

It should be pointed out that the adjustment plate 27 described in the present invention needs to be used in conjunction with two groups of infrared heaters 6 when in use; when preheating of a group of designated areas is completed, one group of infrared heaters 6 is used to heat the adhesive film in the designated area, and at the same time, the preheating work of another group of designated areas is also switched. After preheating of another group of designated areas is completed, another group of infrared heaters 6 is used to heat the designated area of the adhesive film, thereby improving convenience of use.

In order to further improve the ease of use of the adjustment plate 27, exemplarily, as shown in Figures 11, 12 and 13, the present invention also includes that a connecting groove 30 is provided inside the blowing plate 11, one end of the connecting groove 30 is connected to the cavity, and the other end of the connecting groove 30 is connected to a group of sliding grooves 14, the upper surface of the adjustment plate 27 is fixedly connected to one end of a sliding rod 31, a group of the moving rods 9 are provided with a trapezoidal groove 32 on one side away from the gas spring 22, the trapezoidal groove 32 is located on the side of the moving rod 9 close to the first fixed block 7, the end of the sliding rod 31 away from the adjusting plate 27 passes through the connecting groove 30 and is slidably connected to the trapezoidal groove 32, the end of the sliding rod 31 away from the adjusting plate 27 is provided with a guide slope inclined downward, one end of a reset spring 33 is fixedly connected in the connecting groove 30, and the other end of the reset spring 33 is fixedly connected to the outer side of the sliding rod 31.

When in use, when the blowing plate 11 moves, one end of the sliding rod 31 passes through the connecting groove 30 and is slidably connected to the trapezoidal groove 32 of the moving rod 9, and at this time, the first through hole 28 corresponds to the first air outlet 25; when the blowing plate 11 moves to the middle of the moving rod 9, at this time, one end of the sliding rod 31 is pressed and contacted with one side of the trapezoidal groove 32, and the sliding rod 31 is pressed to move the sliding rod 31 in the connecting groove 30, and the sliding rod 31 squeezes the return spring 33 when it moves, and at the same time drives the adjustment plate 27 to move, and after the adjustment plate 27 moves, the first through hole 28 is staggered with the first air outlet 25, and the second through hole 29 corresponds to the second air outlet 26, so as to switch the heating area of the film;

When the blowing plate 11 moves to a certain position, the squeezing rod 10 on the conveyor belt 2 drives the blowing plate 11 to move upward, and the sliding rod 31 relies on the reset effect of the reset spring 33 to restore the sliding rod 31 to the initial state. At this time, the sliding rod 31 is located above the moving rod 9;

When the blowing plate 11 is reset, the extrusion plate 21 on the first fixed block 7 is used to squeeze the blowing plate 11 downward. When the blowing plate 11 moves downward, the upper surface of the moving rod 9 is used to squeeze the inclined surface of the sliding rod 31, so that the sliding rod 31 enters the connecting groove 30 again, and the reset spring 33 is squeezed and accumulated. When the blowing plate 11 moves down to the initial state, the reset effect of the reset spring 33 drives the sliding rod 31 to reset. At this time, the sliding rod 31 is reset and moved to the trapezoidal groove 32 of the moving rod 9, so that the adjustment plate 27 is restored to the initial state. At this time, the next group of adhesive films can be preheated, further improving the convenience of use.

When an embodiment of the present invention is used, the adhesive film is laid on the upper surface of the glass, and the conveyor belt 2 drives the glass to move when it rotates. After the conveyor belt 2 rotates to a certain position, the extrusion rod 10 is pressed and contacted with one side of the blowing plate 11, and the blowing plate 11 is driven to slide on the moving rod 9. The sliding groove 14 can improve the movement stability and convenience of the blowing plate 11.

By connecting the air inlet connector 15 to the air source, when the blowing plate 11 moves, the gas enters the cavity through the air inlet connector 15, and heats the inside of the cavity by relying on the heating wire 12. The gas is finally discharged through the air outlet 13 and blown to the upper surface of a group of glass, so as to preheat the adhesive film laid on the upper surface of the glass, so as to facilitate the subsequent heating by the infrared heater 6, thereby improving the processing efficiency; and, by relying on the air outlet 13 to blow air vertically to the adhesive film, the stability of the adhesive film laid on the glass can also be improved, and the misalignment of the glass and the adhesive film when they move synchronously can be avoided, so as to further ensure the effect of fixing the adhesive film;

When the blowing plate 11 moves to a certain position, one side of the blowing plate 11 is pressed and contacted with the second fixing block 8, and the blowing plate 11 cannot move further by relying on the second fixing block 8. At the same time, relying on the inclined surface provided on the upper end of the squeezing rod 10, the blowing plate 11 is squeezed to move the blowing plate 11 upward. When the blowing plate 11 moves upward, the moving rod 9 is separated from the first magnetic roller 18 and no longer squeezes the pressing switch 19. At this time, the heating wire 12 and the air inlet joint 15 are turned off, which can effectively reduce energy consumption.

When the blowing plate 11 has finished moving up, the squeezing rod 10 no longer squeezes the blowing plate 11, and at the same time, the sliding plate 23 is driven to reset and move by relying on the reset effect of the gas spring 22. When the sliding plate 23 moves, it squeezes the supporting wheel 24, thereby driving the blowing plate 11 to reset and move. When the blowing plate 11 is reset and moved to a certain position, the squeezing plate 21 provided on the first fixed block 7 squeezes the blowing plate 11 to make the blowing plate 11 move downward. When the blowing plate 11 moves downward, the lower surface of the moving rod 9 is separated from the second magnetic roller 20, and the upper surface of the moving rod 9 is magnetically adsorbed by the first magnetic roller 18. When the moving rod 9 is magnetically adsorbed by the first magnetic roller 18, the blowing plate 11 returns to its initial state, and the upper surface of the moving rod 9 is squeezed and contacted with the pressing switch 19, and the air intake of the heating wire 12 and the air intake joint 15 is turned on. At this time, the next group of adhesive films can be preheated again.

When it is necessary to preheat the designated area of the adhesive film, the preheating position of the adhesive film can be adjusted by the adjusting plate 27. When the blowing plate 11 and the glass move synchronously, the adhesive film laid on the upper surface of the glass is preheated. When the blowing plate 11 moves, one end of the sliding rod 31 passes through the connecting groove 30 and is slidably connected with the trapezoidal groove 32 of the moving rod 9. At this time, the first through hole 28 corresponds to the first air outlet 25, so that the gas passes through the first through hole 28 and the first air outlet 25 to preheat the designated area of the adhesive film, further improving the preheating effect. Since the second through hole 29 is staggered with the second air outlet 26, the gas will not be discharged through the second air outlet 26.

When the blowing plate 11 moves to the middle of the moving rod 9, one end of the sliding rod 31 is pressed and contacted with one side of the trapezoidal groove 32, and the sliding rod 31 is pressed to move the sliding rod 31 in the connecting groove 30. When the sliding rod 31 moves, the return spring 33 is pressed, and the adjustment plate 27 is driven to move at the same time. After the adjustment plate 27 moves, the first through hole 28 is staggered with the first air outlet 25, so as to close the air outlet of the first air outlet 25. As the adjustment plate 27 moves, the second through hole 29 will correspond to the second air outlet 26. At this time, the gas will be discharged through the second air outlet 26, so as to preheat the designated area on the other side of the film, improve the preheating effect, and facilitate the preheating of the designated area of the film according to the actual use situation, so as to switch the heating area of the film.

When the blowing plate 11 is reset, the extrusion plate 21 on the first fixed block 7 is used to squeeze the blowing plate 11 downward. When the blowing plate 11 moves downward, the upper surface of the moving rod 9 is used to squeeze the inclined surface of the sliding rod 31, so that the sliding rod 31 enters the connecting groove 30 again, and the reset spring 33 is squeezed and accumulated. When the blowing plate 11 moves down to the initial state, the reset effect of the reset spring 33 drives the sliding rod 31 to reset. At this time, the sliding rod 31 is reset and moved to the trapezoidal groove 32 of the moving rod 9, so that the adjustment plate 27 is restored to the initial state. At this time, the next group of adhesive films can be preheated, further improving the convenience of use.
