Description

Technical Field

[0001] The utility model relates to the technical field of automobile part production, in particular to a heating pad laminating machine. Background Art

[0002] With the improvement of people's living standards, the driving safety and comfort of automobiles have received increasing attention. To improve driving safety, many automobiles are equipped with a hands-off detection system (HOD for short). The hands-off detection technology of the steering wheel is to detect whether the driver's hand leaves the steering wheel and give a reminder and warning, so as to ensure driving safety. With the development of technology, people are no longer satisfied with the HOD function, and also have a heating requirement for the steering wheel, that is, the steering wheel needs to have both heating and HOD functions.

[0003] The current steering wheel heating pad generally includes a hands-off detection HOD function sensing layer, a first double-sided adhesive layer, a shielding layer, a second double-sided adhesive layer, and a heating layer; the first double-sided adhesive layer and the second double-sided adhesive layer are arranged oppositely; the hands-off detection HOD function sensing layer is located on the first side of the first double-sided adhesive layer and is used to detect whether the driver's hand leaves the steering wheel; the heating layer is located on the second side of the second double-sided adhesive layer and is used to heat the steering wheel; the shielding layer is made of conductive cloth and is located between the two double-sided adhesive layers, and the shielding layer is grounded to isolate the hands-off detection HOD function sensing layer and the heating layer. In the production and manufacturing of the steering wheel heating pad, the lamination between layers is a very crucial process. A laminating machine is a machine that heats two or more layers of the same or different materials, such as various plastic films, to a molten or semi-molten state and then bonds them together, or composites two films into one with an adhesive. However, most of the existing laminating machines place two films completely aligned and then press them with a laminating roller. This pressing method may have more bubbles, resulting in poor lamination effect of the two films, and there is only one working station, so the working efficiency is low.

[0004] Patent CN201645953U discloses a reverse-side laminating machine, which includes a rotating shaft bracket, a guide rod cylinder, and a composite material plate. The guide rod cylinder pulls one end of the composite material plate to rotate around the rotating shaft bracket, which can realize the inclination of the composite material plate and make the film gradually adhere from one end to the other end. However, its substrate turnover plate also has only one working station. After each film lamination, the substrate turnover plate needs to rotate back once, which is time-consuming and has low working efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a heating pad laminating machine to solve the problems existing in the above-mentioned prior art, so that the film laminating effect is good and the film laminating efficiency is high.

[0006] To achieve the above purpose, the utility model provides the following scheme:

[0007] The utility model provides a heating pad laminating machine, comprising

[0009] a second adsorption platform which is oppositely arranged to the first adsorption platform. The second adsorption platform includes a sliding platform and an inclinable platform.

When the telescopic frame drives the inclinable platform to incline, the support shaft abuts against the inclinable platform.

[0012] Preferably, a friction block is arranged at the lower end of the inclinable platform and is arranged along the length direction of the inclinable platform for contacting with the support shaft.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] The purpose of the present utility model is to provide a heating pad laminating machine to solve the problems existing in the prior art, so that the film laminating effect is good and the film laminating efficiency is high.

[0029] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] As Figures 1 - 4As shown in the figure, the present utility model provides a heating pad laminating machine, which includes a first adsorption platform 3 and a second adsorption platform. The first adsorption platform 3 is used for adsorbing the first layer of material 101. The first adsorption platform 3 includes a first working station 1011 and a second working station 1012 which are oppositely arranged, and the first adsorption platform 3 can be flipped. The second adsorption platform is arranged opposite to the first adsorption platform 3. The second adsorption platform includes a sliding platform 1 and an inclined platform 2. The inclined platform 2 is used for adsorbing the second layer of material 102. The sliding platform 1 is fixedly connected to the inclined platform 2 through an inclination mechanism. The inclination mechanism is used to incline the inclined platform 2. The sliding platform 1 can drive the inclined platform 2 to slide relative to the first adsorption platform 3. The inclination mechanism inclines the inclined platform 2 so that one end is high and the other end is low. The high end jacks up the second layer of material 102 to contact the first layer of material 101 on the first adsorption platform 3. During the sliding process of the sliding platform 1 (sliding in the direction from the high end to the low end), the high end gradually moves, so that the second layer of material 102 gradually adheres to the first layer of material 101, gradually reducing the generation of bubbles during pasting, improving the film laminating effect. Moreover, the first adsorption platform 3 can be flipped, and two working stations can be used alternately, so the film laminating efficiency is relatively high.

[0031] In some embodiments, a negative pressure mechanism is provided on both the first working station 1011 and the second working station 1012. The negative pressure mechanism includes a vacuum pump. The vacuum pump is used for pumping air to achieve the negative pressure of the first working station 1011 and the second working station 1012 to adsorb the first layer of material 101. The negative pressure mechanism can generate a reliable adsorption force, and can firmly adsorb the first layer of material 101 and the second layer of material 102 at the set positions. Compared with the traditional mechanical clamping or gluing methods, the negative pressure mechanism will not cause any damage to the surface of the adsorbed object. Adsorption is achieved through air pressure, avoiding surface scratches, deformation or contamination caused by excessive clamping force.

[0032] In some embodiments, the tilting mechanism includes a plurality of telescopic frames 21, which are respectively arranged at the lower edge positions of the tiltable platform 2. Both ends of the telescopic frame 21 are fixedly connected to the edges of the sliding platform 1 and the tiltable platform 2. The second adsorption platform further includes a support shaft 5, and the support shaft 5 is arranged between the sliding platform 1 and the tiltable platform 2 through a shaft support frame 51, which can support the tiltable platform 2. When the telescopic frame 21 drives the tiltable platform 2 to tilt, the support shaft 5 abuts against the tiltable platform 2. As a feasible implementation manner, both the first adsorption platform 3 and the second adsorption platform are rectangular structures. Four telescopic frames 21 are provided, which are respectively located at the four corners under the tiltable platform 2. The two telescopic frames 21 at one short side of the rectangle are raised, and the two telescopic frames 21 at the other short side are lowered, so that the support shaft 5 abuts against the middle position of the tiltable platform 2, improving the support effect. It should be noted that other types of tilting mechanisms or support brackets can also be used. For example, two telescopic frames 21 are provided at one short side of the rectangle, and the tilting mechanism at the other short side is rotatably connected to the tiltable platform 2. The shaft support frame 51 is set as a lifting frame, and the telescopic frame 21 can be raised by adjusting the lifting frame so that the support shaft 5 supports the tiltable platform 2.

[0033] In some embodiments, a friction block 6 is provided at the lower end of the tiltable platform 2. The friction block 6 is arranged along the length direction of the tiltable platform 2 and is used to contact the support shaft 5. The contact between the friction block 6 and the support shaft 5 can effectively reduce the shaking of the tiltable platform 2 during operation. The support shaft 5 provides a stable support point for the tiltable platform 2 through the friction block 6, making the movement of the tiltable platform 2 smoother, thus ensuring the overall stability. Moreover, the setting of the friction block 6 prevents the tiltable platform 2 from shaking, keeping the tiltable platform 2 in a set position, thereby ensuring the bonding accuracy of the first layer of material 101 and the second layer of material 102.

[0034] In some embodiments, the second adsorption platform further includes a pressing roller 4 and a pressing roller bracket 41. One end of the pressing roller bracket 41 is fixedly connected to the sliding platform 1 and is located at the edge of the tiltable platform 2 near one end close to the first adsorption platform 3. The other end is rotatably installed with the pressing roller 4 for pressing the first layer of material 101 and the second layer of material 102. Among them, the pressing roller bracket 41 is a telescopic bracket. The pressing roller bracket 41 can be raised so that the pressing roller 4 abuts against the second layer of material 102 located above the pressing roller, and the second layer of material 102 is roll-pressed to make the bonding effect between the second layer of material 102 and the first layer of material 101 good. The pressing roller 4 is preferably set as a pressing roller made of an elastic material. On the one hand, it can protect the second layer of material 102 from being damaged. On the other hand, the elastic pressing roller can provide a relatively uniform pressure distribution during the pressing process. Compared with the traditional rigid pressing roller, it can better adapt to the surface shape change of the second layer of material 102, ensure that the pressure in the entire pressing area is consistent, can perform pressing with higher precision, and can effectively improve the quality and performance stability of the product. It should be noted that the elastic pressing roller made of an elastic material can be made of rubber, polyurethane or an elastic composite material.

[0035] In some embodiments, there are two second adsorption platforms, which are respectively arranged at both ends of the first adsorption platform 3 in the length direction. Preferably, when one second adsorption platform retracts, the other second adsorption platform advances. When one completely retracts, the other that advances is exactly below the first adsorption platform 3, which fully saves time and improves the bonding efficiency.

[0036] In some embodiments, the first adsorption platform 3 includes a first plate body 31, a second plate body 32 and a vertical plate 34. The first plate body 31 and the second plate body 32 are arranged in parallel. Multiple vertical plates 34 are vertically arranged between the first plate body 31 and the second plate body 32. Square through holes and circular through holes are arranged on multiple vertical plates 34. The square through holes are used to connect with the air extraction holes of the vacuum pump, and the circular through holes are used for the rotation shaft 35 of the first driving device 33 to pass through. The first driving device 33 is a motor, and the rotation shaft 35 of the motor passes through the circular through hole and is fixedly connected to the first adsorption platform 3. As a feasible implementation manner, a fixing block is fixedly connected to the end of the rotation shaft 35 of the motor, and both ends of the fixing block are respectively fixedly connected to the end faces of the first plate body 31 and the second plate body 32. What can also be achieved is to directly bond and fix the rotation shaft 35 of the motor to the hole wall of the circular through hole. It should be noted that the square through holes are arranged on both sides of the circular through holes, which can ensure the uniformity of air flow and ensure the negative pressure adsorption effect.

[0037] In some embodiments, the sliding platform 1 is connected with a lead screw. The lead screw is arranged along the length direction of the first adsorption platform 3, and the lead screw is connected with a second driving device. The second driving device can drive the sliding platform 1 to slide along the length direction of the first adsorption platform 3 through the lead screw.

[0038] Specifically, the working process of the heating pad laminating machine is as follows:

[0039] Place the first layer of material 101 on the first station 1011 of the flipping platform. At this time, the second adsorption platform is located on the left side of the first adsorption platform 3. Place the second layer of material 102 on the tiltable platform 2. The first driving device 33 of the flipping platform drives the flipping platform to flip, making the first layer of material 101 face down. At this time, another first layer of material 101 can be placed on the second station 1012. Start the second driving device of the second adsorption platform. Driven by the lead screw, the second driving device drives the second adsorption platform to move to directly below the flipping platform. The two telescopic frames 21 close to the first adsorption platform 3 rise until the second layer of material 102 can contact the first layer of material 101. At the same time, the two telescopic frames 21 away from the first adsorption platform 3 descend until the support shaft 5 can support the tiltable platform 2. Adjust the pressing roller bracket 41 on the right side of the tiltable platform 2 to make the pressing roller 4 fit and abut against the lower part of the second layer of material 102. Then start the second driving device of the second adsorption platform to make the second adsorption platform move to the left and return to the left side of the flipping platform. During the return process, the second layer of material 102 moves relative to the second adsorption platform, and the pressing roller 4 gradually presses the second layer of material 102 to make the second layer of material 102 adhere to the first layer of material 101. When this second adsorption platform returns, the second adsorption platform on the right side of the first adsorption platform 3 advances. This cycle continues.

[0040] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
