[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0044] Example 1

[0045] like Figure 1 , Figure 2 As shown, the automatic film laminating device for automobile plates comprises

[0046] The plate conveying mechanism 10 includes a plurality of support members 14 that move synchronously and intermittently, and a same plate 11 is placed on two adjacent support members 14;

[0047] The film material conveying mechanism 20 conveys the film material 21 intermittently. The film material 21 and the plate 11 are intermittently synchronously set, that is, the plate 11 moves, the film material 21 is conveyed, the plate 11 stops moving, and the film material 21 stops conveying. The moving speed of the plate 11 is consistent with the conveying speed of the film material 21.

[0048] The laminating mechanism 30 includes a rotatable pressure roller 32 and an electric push rod 33. The output end of the electric push rod 33 is connected to a middle plate 34. Two cutters 35 are arranged on the middle plate 34. The distance between the two cutters 35 is the same as the distance between two adjacent plates 11. The overall length of the electric push rod 33 is extended to drive the cutter 35 to move downward, and the overall length of the electric push rod 33 is shortened to drive the cutter 35 to move upward.

[0049] The sheet 11 has a loading station, a laminating station, a film cutting station and an unloading station in the sheet conveying mechanism 10. The sheet 11 is loaded at the loading station and moved to the laminating station. The film material 21 is located between the sheet 11 and the pressure roller 32, and is pressed on the surface of the sheet 11 by the pressure roller 32. It moves to the unloading station, and the electric push rod 33 of the film cutting station drives the cutter 35 to move downward to complete the film cutting operation.

[0050] The laminating method of the automatic laminating device for automobile sheet materials comprises the following steps:

[0051] S1. Material preparation, S11. Plate conveying: The plate 11 is placed on the plate conveying mechanism 10 from the loading station, and the plate conveying mechanism 10 conveys the plate 11; at the same time,

[0052] S12. Film material transport: The film material transport mechanism 20 transports the film material 21, and the transport speeds of the plate 11 and the film material 21 are consistent;

[0053] S2, sheet coating: the sheet 11 and the film material 21 are both conveyed to the coating station, wherein the film material 21 passes between the sheet 11 and the pressing roller 32, and is pressed and coated on the surface of the sheet 11 by the pressing roller 32, thus completing the coating work;

[0054] At the same time, the loading station is carrying out the loading of the plate 11;

[0055] S3, film material cutting: the plate 11 that has completed the film coating work is transported to the unloading station through the film cutting station. At this time, the conveying action of the plate 11 and the film material 21 is stopped, and the electric push rod 33 located at the film cutting station drives the cutter 35 to move downward to complete the film cutting work;

[0056] At the same time, the laminating station is performing laminating work on the plate 11; the loading station is performing loading work on the plate 11;

[0057] S4, unloading: the sheet 11 after film cutting is unloaded at the unloading station;

[0058] At the same time, the film material 21 is cut at the film cutting station; the plate 11 is coated at the film coating station; and the plate 11 is loaded at the loading station.

[0059] In the technical solution of the automatic film coating device for automobile sheets, after the sheet 11 is loaded at the loading station, the support member 14 drives the sheet 11 to move to the right side and moves to the film coating station. The film material 21 located between the sheet 11 and the pressure roller 32 is pressed on the surface of the sheet 11 by the pressure roller 32 and moves to the unloading station, that is, between the tail end of the sheet 11 after the film coating and the head end of the sheet 11 to be coated, and moves to the film cutting station. The conveying of the sheet 11 and the film material 21 stops, and the electric push rod 33 drives the cutter 35 to move downward to complete the film cutting operation. The sheet 11 after the film coating is completed is unloaded from the unloading station.

[0060] In the present technical solution, the plate material conveying mechanism 10 conveys the plate material 11, and the film material conveying mechanism 20 conveys the film material 21, and the two are carried out synchronously. The film material 21 is pressed onto the surface of the plate material 11 by a pressure roller 32. After the coating is completed, the cutter 35 moves downward to complete the film cutting operation. The operation is simple and the continuous automatic coating process of the plate material 11 is completed.

[0061] At the same time, because the film material 21 is first pressed by the pressing roller 32 and then cut by the cutter 35, that is, it is first passed by the roller 32 and then by the cutter 35, when the film cutting operation is completed, the pressing roller 32 has pressed the film material 21 on the head of the next plate material 11 to be coated, thereby avoiding the problem that the film material 21 deviates from the conveying path when being cut and the film material 21 cannot be conveyed continuously.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the support member 14 includes a shell 141, the shell 141 has a longitudinally distributed through hole 142, a U-shaped plate 143 is arranged inside the through hole 142 to move in the up and down direction, a pressing plate 145 and a servo motor 144 that drives the pressing plate 145 to rotate are arranged in the U-shaped plate 143, the servo motor 144 can drive the pressing plate 145 to rotate in the forward and reverse directions, and the length of the front movable section of the pressing plate 145 is greater than the length of the rear movable section;

[0063] After the film cutting operation is completed, the U-shaped plate 143 at the film cutting station moves upward, and the servo motor 144 drives the pressing plate 145 to rotate counterclockwise until the front movable section of the pressing plate 145 presses the end surface of the film coated on the sheet 11; the sheet 11 coated with the head is pressed, and the film material 21 coated on the sheet 11 is squeezed and positioned to avoid the problem of loose film coating on the head of the sheet 11 at the beginning of the coating. After the support member 14 moves to the unloading station, the servo motor 144 drives the pressing plate 145 to rotate in the opposite direction until the pressing plate 145 is reset.

[0064] At the same time, the U-shaped plate 143 drives the pressure plate 145 to move upward, so that the film material 21 covered on the support member 14 after cutting is lifted up and adheres to the pressure plate 145, so as to avoid the cut film material 21 adhering to the support member 14 after multiple coating operations, so that the surface height of the support member 14 is higher than the plate 11, which affects the coating effect.

[0065] like Figure 5 , Figure 6 As shown, a groove 146 is provided on the shell 141, and a block 147 that slides with the groove 146 is connected to the outer wall of the U-shaped plate 143, the upper end of the block 147 is against the inner top wall of the groove 146, and a spring 148 is connected between the lower end of the block 147 and the inner bottom wall of the groove 146.

[0066] The U-shaped plate 143 is slidably matched with the groove body 146 through the block body 147, and the spring 148 supports the block body 147, so that the U-shaped plate 143 protrudes from the through hole 142. During the laminating operation, the pressure roller 132 first passes through the housing 141, and the U-shaped plate 143 moves downward under pressure. After the pressure roller 132 passes over the housing 141, the U-shaped plate 143 moves upward and resets under the action of the spring 148.

[0067] To prevent the U-shaped plate 143 from moving upwards and lifting the film before cutting, thereby affecting the laminating effect, Figure 1 , Figure 2 , Figure 6 As shown, the laminating mechanism 30 further includes a second pressing roller 36, and the second pressing roller 36 is connected to the middle plate 34 through an elastic member 37;

[0068] The pressure roller 1 32 first passes through the shell 141 to press the U-shaped plate 143 downward, and then the pressure roller 2 36 passes through the shell 141 to press the U-shaped plate 143 downward. The distance between the lowest point of the pressure roller 1 32 and the lowest point of the pressure roller 2 36 is greater than the width of the shell 141, so that before the film cutting operation is performed, the U-shaped plate 143 is always maintained at a position inside the through hole 142 to prevent the U-shaped plate 143 from moving upward to lift up the film and affect the coating effect.

[0069] like Figure 2 , Figure 6 As shown, the elastic member 37 includes a rod body 371 rotatably matched with the pressure roller 36, and a sleeve 372 connected to the middle plate 34. The movable end of the rod body 371 is inserted into the interior of the sleeve 372, and a spring 2 373 is arranged between the movable end of the rod body 371 and the middle plate 34. When the rod body 371 or the sleeve 372 is squeezed by external force, the spring 2 373 is compressed and the overall length of the elastic member 37 is shortened.

[0070] The setting of the elastic member 37 allows the pressure roller 36 to have a margin for moving in the up and down directions. When the cutter 35 is in the initial position, the pressure roller 36 is in contact with the shell 141. When the cutter 35 moves downward, the overall length of the elastic member 37 is shortened, and the pressure roller 36 is still in contact with the shell 141.

[0071] To realize the installation of the pressure roller 32, as Figure 2 As shown, the laminating mechanism 30 further includes an upper plate 31 , and a pressure roller 32 is connected to the upper plate 31 via an elastic member 37 .

[0072] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the front and rear ends of the shell 141 are both provided with positioning grooves 149 , and the plate 11 is located inside the positioning grooves 149 to ensure the stability of the position of the plate 11 during the lamination process.

[0073] The upper end surface of the plate 11 and the upper end surface of the shell 141 are at the same height line, which ensures the flatness of the film material 21 during the lamination process and ensures the lamination effect.

[0074] To achieve the requirement of synchronous intermittent movement of multiple support members 14, such as Figure 1 As shown, the plate conveying mechanism 10 includes at least two conveying rollers 12 and a conveying belt 13 rotatably cooperated with the conveying rollers 12, wherein a driving member is provided on one of the conveying rollers 12, and the driving member can be set as a motor; a plurality of supporting members 14 are equidistantly distributed on the conveying belt 13.

[0075] The driving member starts to drive the multiple supporting members 14 to move synchronously through the conveying rollers 12 and the conveying belt 13. The moving direction is as follows: Figure 1 At the same time, the driving member can be turned off to control the movement of the support member 14 to stop, thereby realizing the setting requirement of synchronous intermittent movement of multiple support members 14.

[0076] In order to realize the setting requirements of intermittent delivery of the film material 21, Figure 1 As shown, the film material conveying mechanism 20 includes a reel 22, a tension adjustment roller 23 and a clamping conveying member 24. The film material roll of the released film material 21 is arranged on the reel 22. The reel 22 is provided with a driving member, which can be set as a motor; the clamping conveying member 24 is two clamping rollers distributed up and down, and the two clamping rollers are arranged to rotate relative to each other.

[0077] The drive unit is powered on and started, and the unwinding roller 22 rotates to release the film 21 on the film roll. The film 21 passes under the tension adjustment roller 23, the middle of the clamping conveyor 24, and reaches between the plate 11 and the pressure roller 32. The moving direction is Figure 1At the same time, the unwinding roller 22 can be controlled to stop rotating by turning off the driving member, thereby realizing the setting requirement of intermittent conveying of the film material 21.

[0078] The tension adjustment roller 23 is provided to adjust the tension of the film material 21 during the conveying process to avoid uneven tension and affect the coating quality; the clamping conveying member 24 is provided so that the film material 21 passes through two clamping rollers distributed above and below, and the two clamping rollers clamp and convey the film material 21 to avoid the head end of the film material 21 from escaping from the conveying path after the cutting operation, which affects the integrity of the conveying of the film material 21; the film material conveying mechanism 20 is provided to convey the film material 21 stably.

[0079] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
