[0021] In order to make the technical solutions and advantages of the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0022] Embodiment 1 The present embodiment provides an aerogel paste release paper equipment, comprising a first feeding device, a second feeding device, a mechanical arm 1, a vacuum generator.

[0023] The first feeding device comprises a sliding rail 2, a sliding table 3 and a first driving mechanism. The sliding table 3 is in sliding cooperation with the sliding rail 2, and the first driving mechanism is used to drive the sliding table 3 to slide. The sliding table 3 is provided with a negative pressure hole 4, and the negative pressure hole 4 is connected with the vacuum generator. The sliding table 3 is used to place the gel material 8. For example, referring to Figure 1 The equipment comprises a box structure 17 with a front opening. The sliding rail 2 is arranged in the front-rear direction, and the rear end part of the sliding rail 2 extends into the box structure 17. The sliding table 3 is slidingly arranged on the sliding rail 2. The first driving mechanism can drive the sliding table 3 to slide forward and backward, that is, the sliding table 3 can automatically slide forward and backward and in and out of the box structure 17. The first driving mechanism is a prior art, such as a pneumatic cylinder or other moving device. Referring to Figure 2 The sliding table 3 is provided with an array of millimeter-level negative pressure holes 4 (the aperture of the negative pressure hole 4 can be 1 mm). The negative pressure holes 4 are connected with the vacuum generator through a pipeline. The vacuum generator is used to create a vacuum effect, so that the negative pressure holes 4 have a negative pressure adsorption effect, and the adsorption pressure is adjustable (0.1-0.5 kPa). The wrapped gel material 8 is placed on the sliding table 3, and then the vacuum generator is used to create a vacuum, so that the gel material 8 is stably adsorbed on the sliding table 3. The size of the gel material 8 is 300x200 mm, and the pressing force is 2 N.

[0024] The second feeding device comprises a conveyor belt 5, which is used to transport the release paper 6. For example, referring to Figure 1 The conveyor belt 5 is drivingly arranged inside the box structure 17, and the conveyor belt 5 is located on the right side of the sliding rail 2. The surface of the conveyor belt 5 is coated with a silicone oil layer, and the release paper 6 is pasted on the silicone oil layer. Due to the arrangement of the silicone oil layer, the adhesion of the release paper 6 on the conveyor belt 5 is weak, and it is easy to separate from the conveyor belt 5 when an external force is applied. At the same time, the conveyor belt 5 can also transport the release paper 6 when it is driven.

[0025] The moving end of the mechanical arm 1 is provided with a suction cup 7, and the suction cup 7 is connected with the vacuum generator. For example, referring to Figure 1The mechanical arm 1 is arranged inside the box structure 17, and the movable end of the mechanical arm 1 is detachably provided with an array suction cup 7. The suction cup 7 is connected with a vacuum generator through a pipeline. The suction cup 7 is used for adsorption under the action of negative pressure generated by the vacuum generator. The array suction cup 7 is adapted to the size of the release paper 6, and the array suction cup 7 is distributed in a size of 200*150mm. The release paper 6 can be adsorbed on the suction cup 7 by the vacuum generator.

[0026] In summary, the aerogel and release paper equipment provided by the embodiment can realize automatic operation of aerogel and release paper bonding, greatly improve production efficiency, reduce labor intensity, meet the needs of large-scale production, and significantly improve efficiency compared with traditional manual bonding.

[0027] Therefore, the device can realize the automatic operation of aerogel and release paper bonding, greatly improve production efficiency, reduce labor intensity, meet the needs of large-scale production, and significantly improve efficiency compared with traditional manual bonding.

[0028] The negative pressure hole 4 can effectively prevent the gel material 8 from moving during transportation on the sliding table 3, ensure the bonding accuracy, and have better stability and higher accuracy than traditional manual or simple clamp fixing methods. Moreover, the adsorption force can be adjusted to adapt to different production rhythms.

[0029] The mechanical arm 1 drives the suction cup 7 to adsorb and move the release paper 6, and the adsorption force is uniform and stable, so that the release paper 6 can be quickly and accurately taken and bonded, avoiding problems such as bonding deviation and blistering that may occur in manual operation, and effectively improving product quality.

[0030] The mechanical arm 1 is a prior art, and the mechanical arm 1 can include a moving mechanism in left-right direction and a lifting mechanism. The lifting mechanism is installed on the moving end of the moving mechanism, and the suction cup 7 is installed on the lifting end of the lifting mechanism. The moving mechanism can drive the lifting mechanism to move left and right, and then the lifting mechanism can realize the up-down movement of the suction cup 7, and further realize the up-down and left-right movement of the suction cup 7.

[0031] The box structure 17 can play a protective role to avoid the interference of the external environment on the lamination process of the gel material 8 and the release paper 6. When the sliding table 3 slides to the outside of the box structure 17, the gel material 8 is conveniently manually taken or placed.

[0032] On the basis of the above technical scheme, in the technical scheme provided by the embodiment, the second feeding device further comprises a discharging roller 9, a winding roller 10, a flattening table 16 and a second driving mechanism, the discharging roller 9 and the winding roller 10 are located on the same side of the flattening table 16, one end of the conveying belt 5 is wound on the discharging roller 9, the other end of the conveying belt 5 is wound on the winding roller 10 through the flattening table 16, and the second driving mechanism is used to drive the winding roller 10 to rotate. For example, referring to Figure 3 The flattening table 16 is horizontally fixedly installed on the inner side wall of the box structure 17, the discharging roller 9 and the winding roller 10 are both rotationally arranged on the inner side wall of the box structure 17 through supports, the discharging roller 9 and the winding roller 10 are both located on the right side of the flattening table 16, and the discharging roller 9 is located above the winding roller 10. One end of the conveying belt 5 is wound on the discharging roller 9, the other end of the conveying belt 5 passes above the flattening table 16, then winds from the left end of the flattening table 16 to below the flattening table 16, and finally winds on the winding roller 10. The second driving mechanism can drive the winding roller 10 to rotate, and the second driving mechanism can be a motor, a rotary air cylinder or the like. The second driving mechanism drives the winding roller 10 to rotate, which can drive the discharging roller 9 to rotate, the conveying belt 5 is released from the discharging roller 9, then passes above the flattening table 16 from right to left and is finally wound on the winding roller 10, so that the transmission of the conveying belt 5 is realized.

[0033] The flattening table 16 is horizontally arranged, and when the mechanical arm 1 moves the suction cup 7 to adsorb the release paper 6 on the conveying belt 5, the release paper 6 above the flattening table 16 can be selected to be adsorbed, so that the flattening table 16 can play a role of receiving, so that the suction cup 7 is in full contact with the release paper 6, and the release paper 6 on the conveying belt 5 can be smoothly adsorbed by the suction cup 7.

[0034] In the technical scheme provided by the embodiment, the second feeding device further comprises a first guide roller 11, the first guide roller 11 is located between the discharging roller 9 and the flattening table 16, and the bottom end of the first guide roller 11 is flush with the top end of the flattening table 16. For example, referring to Figure 3The rotating shaft is fixedly installed on the inner side wall of the box structure 17, the first guide roller 11 is rotatably sleeved outside the rotating shaft, and the first guide roller 11 is located between the discharging roller 9 and the flattening table 16, and the bottom end of the first guide roller 11 is flush with the top end of the flattening table 16. After the conveying belt 5 is released from the discharging roller 9, it first passes under the first guide roller 11 and then passes through the flattening table 16. Since the bottom end of the first guide roller 11 is flush with the top end of the flattening table 16, the conveying belt 5 is flush with the top end of the flattening table 16 when passing through the first guide roller 11. In this way, when the conveying belt 5 passes above the flattening table 16 from right to left, the conveying belt 5 can be attached to the surface of the flattening table 16, so that the conveying belt 5 at this position can be kept horizontal, and the release paper 6 on the conveying belt 5 can be kept horizontal, so that the mechanical arm 1 can be more accurately positioned when moving the suction cup 7 to adsorb the release paper 6.

[0035] In the technical scheme provided in the embodiment, the second feeding device further comprises a second guide roller 12, the second guide roller 12 is located between the discharging roller 9 and the first guide roller 11, and a pressure sensor is arranged on the surface of the second guide roller 12, and the pressure sensor is used for detecting the pressure of the conveying belt 5. For example, referring to Figure 3 The rotating shaft is fixedly installed on the inner side wall of the box structure 17, the second guide roller 12 is rotatably sleeved outside the rotating shaft, and the second guide roller 12 is located between the discharging roller 9 and the first guide roller 11. After the conveying belt 5 is released from the discharging roller 9, it first passes under the second guide roller 12 and then passes through the first guide roller 11. The pressure sensor is arranged on the surface of the second guide roller 12 in the circumferential direction, and the pressure sensor can detect the pressure of the conveying belt 5, so that the tension state of the conveying belt 5 can be determined according to the pressure.

[0036] In the technical scheme provided in the embodiment, the second feeding device further comprises a third guide roller 13, a fourth guide roller 14 and a fifth guide roller 15, and the third guide roller 13, the fourth guide roller 14 and the fifth guide roller 15 are all located between the flattening table 16 and the winding roller 10. For example, referring to Figure 3The third guide roller 13, the fourth guide roller 14 and the fifth guide roller 15 are respectively rotatably sleeved outside the three rotating shafts, and the third guide roller 13, the fourth guide roller 14 and the fifth guide roller 15 are located between the flattening table 16 and the winding roller 10. The fourth guide roller 14 and the fifth guide roller 15 are located on the right side of the third guide roller 13, and the fourth guide roller 14 is located on the lower side of the fifth guide roller 15. The conveying belt 5 passes above the flattening table 16 from right to left, is wound to the lower side of the flattening table 16 from the left end of the flattening table 16, is wound from the lower side of the third guide roller 13, is wound from the right side of the fourth guide roller 14, is finally wound from the left side of the fifth guide roller 15, and is wound on the winding roller 10. The third guide roller 13, the fourth guide roller 14 and the fifth guide roller 15 can play a guiding and buffering role.

[0037] In the technical scheme provided in the embodiment, the flattening table 16 is provided with a guide slope at one end close to the discharging roller 9, and the top end of the guide slope is flush with the top end of the flattening table 16. For example, referring to Figure 3 The flattening table 16 is provided with a guide slope at the right end, the top end of the guide slope is flush with the top end of the flattening table 16, and the guide slope can play a guiding role to avoid the phenomenon of jamming of the conveying belt 5 at the right end of the flattening table 16.

[0038] In the technical scheme provided in the embodiment, the flattening table 16 is a smooth curved surface structure away from one end of the discharging roller 9. For example, referring to Figure 3 The left end of the flattening table 16 is a smooth curved surface structure, and the friction between the conveying belt 5 and the flattening table 16 is small when the conveying belt 5 passes through the left end of the flattening table 16, so that the transmission of the conveying belt 5 is more smooth.

[0039] Further, referring to Figure 4 The flattening table 16 is provided with a support 20 on the left side, the flattening table 16 is provided with two sliding holes 18 on the left end, a sliding rod 19 is slidably sleeved in the sliding hole 18, the left end of the sliding rod 19 is fixedly connected with the support 20, a buffer roller 21 is rotatably arranged on the support 20, and the right end of the sliding rod 19 is connected with the inner wall of the sliding hole 18 through a spring 22.

[0040] The buffer roller 21 is coaxial with other rollers, and the buffer roller 21 is aligned with the upper and lower ends of the flattening table 16. After the conveying belt 5 passes above the flattening table 16 from right to left, it is wound from the left side of the buffer roller 21 to below the flattening table 16. Since the buffer roller 21 can rotate freely, the friction between the conveying belt 5 and the buffer roller 21 can be reduced. At the same time, due to the action of the spring 22, the sliding rod 19, the support 20 and the buffer roller 21 can move left and right, so that the buffer roller 21 can play a buffering role. Specifically, when the winding roller 10 rotates faster, the conveying belt 5 is tightened, the buffer roller 21 moves to the right, and the spring 22 is compressed and shortened, which can prevent the conveying belt 5 above the flattening table 16 from being stretched and deformed. Conversely, when the winding roller 10 rotates slower, the conveying belt 5 becomes loose, the buffer roller 21 moves to the left, and the spring 22 is stretched and lengthened, which can prevent the conveying belt 5 above the flattening table 16 from being loose.

[0041] In the technical scheme provided by the embodiment, referring to Figure 5 The front and rear ends of the sliding table 3 are fixedly provided with limiting plates, the rear end limiting plate is provided with a clamping groove matched with the gel material 8, and the clamping groove has a larger diameter as it is closer to the front end. When the gel material 8 is placed on the sliding table 3, the rear end of the gel material 8 can be embedded in the clamping groove, and the front end of the gel material 8 abuts against the front end limiting plate, so that the stability of the gel material 8 can be effectively improved, the gel material 8 can be prevented from sliding forward and backward, and the gel material 8 can be conveniently manually taken off.

[0042] The aerogel and release paper equipment provided by the embodiment further comprises a PLC controller, and the controller is electrically connected with the first driving mechanism, the second driving mechanism, the mechanical arm 1, the vacuum generator and the pressure sensor. The controller serves as a core control unit and is pre-set with various action programs and parameters. An operator can set parameters and input operation instructions through a man-machine interface of the controller. The controller can also monitor the running states of various parts of the equipment in real time, such as the conveying speed of the conveying belt and the suction force of the suction cup, and automatically adjusts to ensure stable and efficient operation of the equipment. Moreover, when a fault occurs, the system will automatically alarm and stop, ensuring the safety of the equipment and personnel. The equipment can adapt to the bonding requirements of aerogels and release papers of different specifications and models, and has good versatility and flexibility.
