Description

Technical Field

[0001] The present invention relates to the technical field of aerogel processing, and specifically to a single / double-sided grinding device for aerogel sheets in coordination with transportation and an aerogel sheet processing method. Background Art

[0002] Aerogel sheets are usually composed of a composite of aerogel and a substrate. Specifically, it may include an upper substrate, an aerogel thermal insulation coating, and a lower substrate that are bonded in sequence from top to bottom.

[0003] The appearance of the upper and lower surfaces of aerogel products is inconsistent, or there are defects such as foreign objects and wrinkles. In order to improve the appearance consistency and aesthetic degree of the products, it is most important to improve the surface roughness of the products to increase the firmness of the surface film. Usually, the products need to be ground. The ground products can significantly improve the appearance consistency and aesthetic degree and enhance the firmness of the surface film.

[0004] Existing sheet grinding usually synchronously grinds both sides of the sheet through a grinding device. Since the thickness and the required grinding amount of each sheet grinding are different, it is necessary to adjust the distance between the two grinding rollers. When the grinding rollers are adjusted, the central horizontal reference plane of their grinding may change, and the sheet cannot enter between the two grinding rollers perpendicular to the grinding plane.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] This application can use a grinding device to position and clamp the aerogel sheet before grinding through this aerogel sheet processing method to ensure the best accuracy of the two sides of the sheet to be ground. Specifically, when the conveyor belt transports the sheet to the position where it cooperates with the clamping plate, under the action of the spacing adjustment component, the translation clamping mechanism controls the movement of the clamping plate to clamp the sheet. At the same time, the translation clamping mechanism controls the clamping plate to move in the horizontal direction, and under the action of the lifting guiding mechanism, the clamping plate controls the sheet to rise to the position where it cooperates with the first grinding roller and the second grinding roller. The central horizontal reference plane between the two clamping plates at the front end is located on the same horizontal plane as the central horizontal reference plane between the first grinding roller and the second grinding roller, so as to ensure that the distances between the two sides of the sheet to be ground from the first grinding roller and the second grinding roller are the same, ensuring that the grinding amounts on both sides of the sheet are the same, and preventing the problem of uneven grinding on both sides caused by the inclination of the sheet edge. When the sheet is inserted between the first grinding roller and the second grinding roller, under the action of the grinding adjustment mechanism, the first grinding roller and the second grinding roller are controlled to rotate to synchronously grind the two sides of the sheet. By clamping and positioning the aerogel sheet before grinding, the uniformity and consistency of grinding on both sides of the sheet can be ensured, and ultimately the purpose of increasing the surface roughness can be achieved.

[0030] Through the grinding adjustment mechanism, when adjusting the grinding amount, the central horizontal reference plane between the first grinding roller and the second grinding roller will never change, thus avoiding the problem of uneven grinding of the sheet caused by the change of the grinding reference plane due to the adjustment of the positions of the first grinding roller and the second grinding roller.

[0031] The double-headed cylinder can be used to synchronously control the two clamping plates to move towards each other or away from each other to clamp sheets of different sizes. At the same time, it can also ensure that the central horizontal reference plane between the two clamping plates remains unchanged during the adjustment process to ensure the best accuracy of subsequent grinding.

When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0045] Please refer to Figures 1 to 10 , in the embodiment of the present invention, a single / double-sided grinding device for aerogel sheets in cooperation with conveying includes:

[0046] A processing machine table 1, and supporting plates 2 which are symmetrically arranged and installed in the processing machine table 1. Conveying rollers 3 which are symmetrically arranged are rotatably installed on the supporting plates 2. A conveyor belt 4 is sleeved on the conveying rollers 3. A fixing plate 13 is also arranged on the supporting plate 2;

[0047] It further includes:

[0048] A grinding adjustment mechanism is arranged on the supporting plate 2. A first grinding roller 8 and a second grinding roller 9 are connected to the grinding adjustment mechanism. The grinding adjustment mechanism can adjust the distance between the first grinding roller 8 and the second grinding roller 9 and drive the first grinding roller 8 and the second grinding roller 9 to rotate;

[0049] A translation clamping mechanism is arranged on the fixing plate 13. Clamping plates 23 which are symmetrically arranged are connected to the translation clamping mechanism. A lifting guiding mechanism connected to the translation clamping mechanism is arranged on the supporting plate 2. The translation clamping mechanism can drive the lifting guiding mechanism to move so as to control the clamping plates 23 to move along the length direction of the supporting plate 2 and move in the vertical direction at the same time;

[0050] A distance adjustment component is arranged on the translation clamping mechanism and is used to adjust the distance between the clamping plates 23 through the translation clamping mechanism.

[0051] Specifically, when grinding one or both sides of the aerogel sheet, in order to ensure more uniform grinding on both sides, it is necessary to center-position and push the aerogel sheet to prevent uneven grinding on both sides caused by the inclination of the sheet edge. Therefore, according to the required grinding amount of the aerogel sheet, the distance between the first grinding roller 8 and the second grinding roller 9 can be adjusted through the grinding control mechanism. At the same time, the aerogel sheet is placed on the conveyor belt 4, and under the action of the conveyor roller 3, the conveyor belt 4 is driven to move so that the aerogel is transported to the position where it cooperates with the clamping plate 23. At this time, under the action of the distance control assembly, the two clamping plates 23 are controlled to move towards each other through the translation clamping mechanism until the two clamping plates 23 are in contact with both sides of the aerogel sheet and the sheet is separated from the conveyor belt 4. At the same time, under the action of the translation clamping mechanism and the lifting and guiding mechanism, while controlling the aerogel sheet to move towards the first grinding roller 8 and the second grinding roller 9 through the clamping plate 23, it is moved vertically to the central position between the first grinding roller 8 and the second grinding roller 9 to ensure that both sides of the aerogel sheet are synchronously in contact with the first grinding roller 8 and the second grinding roller 9, and to ensure that the grinding areas and grinding pressures on both sides of the sheet are consistent until the sheet grinding is completed. Through the clamping and positioning of the aerogel sheet before grinding, the uniformity and consistency of grinding on both sides of the sheet can be ensured, and the expected surface roughness can be achieved.

[0052] Please refer to Figure 3 、 Figure 4 、 Figure 6 、 Figure 10 The grinding control mechanism includes support plates 5 symmetrically installed on the support plate 2. Symmetrically arranged first chutes 501 are provided on the support plates 5. First sliding blocks 6 are slidably installed in the first chutes 501. The two first sliding blocks 6 are respectively rotatably connected to the first grinding roller 8 and the second grinding roller 9. A bidirectional pushing assembly connected to the first sliding blocks 6 is provided on the support plates 5. Among them, the bidirectional pushing assembly includes a bidirectional screw rod 10 rotatably installed on the support plates 5. Symmetrically arranged first threaded sleeves 11 are threadedly connected to the bidirectional screw rod 10. Fixed blocks 12 fixedly connected to the first sliding blocks 6 are provided on the side walls of the first threaded sleeves 11. It also includes motors 7 installed on the first sliding blocks 6. The output shafts of the two motors 7 are respectively connected to the first grinding roller 8 and the second grinding roller 9.

[0053] Specifically, when grinding the aerogel sheet, it is necessary to adjust the distance between the first grinding roller 8 and the second grinding roller 9 to adapt to sheets of different thicknesses and the required grinding amount. In the initial state, the distance between the first grinding roller 8 and the second grinding roller 9 is relatively large, and the distance between the two first sliding blocks 6 is the largest. When it is necessary to adjust the grinding amount, at this time, the bidirectional lead screw 10 rotates and drives the two first threaded sleeves 11 to move, so as to drive the two first sliding blocks 6 to move along the length direction of the first chute 501 through the fixed block 12. The first sliding block 6 and the first chute 501 play a guiding role, which can ensure that the first threaded sleeve 11 moves along the length direction of the bidirectional lead screw 10 and does not rotate following the bidirectional lead screw 10. The two first sliding blocks 6 will move towards each other to reduce the distance between the first grinding roller 8 and the second grinding roller 9. When the distance adjustment is completed, the bidirectional lead screw 10 stops rotating.

[0054] Preferably, due to the self-locking function of the bidirectional lead screw 10, it can ensure that when the motor 7 controls the rotation of the first grinding roller 8 and the second grinding roller 9, the first sliding block 6 will not be displaced due to the reaction force generated during grinding, thus ensuring the stability and accuracy of grinding. At the same time, since the first grinding roller 8 and the second grinding roller 9 move towards or away from each other synchronously and at the same movement speed, therefore, the central horizontal reference plane between the first grinding roller 8 and the second grinding roller 9 will never change, thus avoiding the problem that the reference plane for grinding changes due to the adjustment of the positions of the first grinding roller 8 and the second grinding roller 9, resulting in uneven grinding of the sheet.

[0055] Please refer to Figures 1 - 6 、 Figure 8 、 Figure 9 As shown in, the translation clamping mechanism includes a unidirectional lead screw 14 rotatably installed on the fixed plate 13. Symmetrically arranged second threaded sleeves 15 are threadedly connected to the unidirectional lead screw 14. A support sleeve 16 is arranged on the second threaded sleeve 15. A support rod 18 is slidably installed in the support sleeve 16. A sliding component is arranged on the support rod 18. Among them, the sliding component includes a receiving plate 20 installed at the end of the support rod 18. A movable plate 21 is arranged on the receiving plate 20. Second chutes 2101 are symmetrically arranged on the movable plate 21. Second sliding blocks 22 are slidably installed in the second chutes 2101. The second sliding blocks 22 are fixedly connected to the clamping plates 23.

[0056] It should be noted that there are four one-way lead screws 14 in total. Two of the one-way lead screws 14 are located at the front end of the first grinding roller 8, and the other two one-way lead screws 14 are located at the rear end of the first grinding roller 8. Therefore, two sets of clamping plates 23 are provided at the front end position of the first grinding roller 8, and two sets of clamping plates 23 are also provided at the rear end position of the first grinding roller 8. Each set of clamping plates 23 is symmetrically distributed on the movable plate 21. In the initial state, the second threaded sleeve 15 at the front end position is at the end of the stroke in the direction away from the first grinding roller 8, and the second threaded sleeve 15 at the rear end position is at the end of the stroke in the direction towards the first grinding roller 8. Under the action of the lifting and guiding mechanism, the support rod 18 at the front end position is at the end of the stroke in the support sleeve 16, and the support rod 18 at the rear end position is at the end of the stroke in the direction away from the support sleeve 16. Therefore, the distance between the two sets of clamping plates 23 at the front end position and the conveyor belt 4 is the smallest, and the distance between the two sets of clamping plates 23 at the rear end position and the conveyor belt 4 is the largest. Moreover, the central horizontal reference plane between the two clamping plates 23 at the rear end is on the same horizontal plane as the central horizontal reference plane between the first grinding roller 8 and the second grinding roller 9. Under the action of the distance adjustment component, the distances between the four sets of clamping plates 23 are all in the maximum state, so that the distance between the two second sliding blocks 22 is the largest.

[0057] Specifically, when the conveyor belt 4 conveys the aerogel sheet to the position where it cooperates with the front clamping plate 23, at this time, the conveyor belt 4 stops working. Under the action of the distance adjustment component, the two second sliding blocks 22 at the front end are controlled to move towards each other, thereby driving the clamping plate 23 to move. When the two sets of clamping plates 23 both move to the position where they abut against the sheet, the end of the sheet away from the first grinding roller 8 is fixedly clamped. At this time, the two one-way lead screws 14 at the front end rotate synchronously and at the same speed, so that the two second threaded sleeves 15 move synchronously and move towards the first grinding roller 8. At the same time, under the action of the lifting and guiding mechanism, the support rod 18 moves in the direction away from the support sleeve 16, thereby controlling the movement of the sheet. When the dimension of the mutual nesting between the support rod 18 and the support sleeve 16 is the smallest, the central horizontal reference plane between the two clamping plates 23 at the front end is on the same horizontal plane as the central horizontal reference plane between the first grinding roller 8 and the second grinding roller 9, so as to ensure that the distances between the two surfaces of the sheet to be ground and the first grinding roller 8 and the second grinding roller 9 are the same. The one-way lead screw 14 continues to rotate, so that the sheet is smoothly inserted between the first grinding roller 8 and the second grinding roller 9. The motor 7 will control the first grinding roller 8 and the second grinding roller 9 to rotate, and the rotation speeds are the same and the rotation directions are opposite, so as to synchronously grind the two surfaces of the sheet.

[0058] Preferably, when the polished sheet enters the position where it cooperates with the rear clamping plate 23, the spacing control assembly controls the rear clamping plate 23 to clamp the sheet, so as to synchronously clamp both ends of the sheet, ensure that the sheet moves more stably, and make the polishing accuracy higher. When the front clamping plate 23 is about to move to the end of the stroke towards the first polishing roller 8, the spacing control assembly controls the two front clamping plates 23 to move away from each other. At the same time, the rear clamping plate 23 can control the rear part of the sheet to gradually separate from the front part, so that the sheet is completely polished. After the sheet is polished, under the action of the lifting and guiding mechanism, the supporting rod 18 at the rear end moves towards the inside of the supporting sleeve 16 until the fitting dimension between the supporting rod 18 and the supporting sleeve 16 reaches the maximum. Under the action of the spacing control assembly, the two rear clamping plates 23 move away from each other, so that the polished sheet is released onto the conveyor belt 4 again. Under the action of the conveyor belt 4, the polished sheet is conveyed out of the processing machine 1. Among them, when the fitting dimension between the supporting rod 18 and the supporting sleeve 16 is the largest, the distance between the two clamping plates 23 and the conveyor belt 4 is the smallest, and the distance between one of the clamping plates 23 below the conveyor belt 4 and the conveyor belt 4 is smaller than the distance between the other clamping plate 23 above the conveyor belt 4 and the conveyor belt 4, ensuring that when the two clamping plates 23 clamp the sheet, the sheet can be controlled to separate from the conveyor belt 4 to prevent interference between the sheet and the conveyor belt 4 when the clamping plate 23 clamps the sheet, resulting in damage to the aerogel sheet.

[0059] Through the mutual cooperation of the two groups of clamping plates 23 at the front end and the rear end, it is possible to first clamp and position one end of the sheet through the front clamping plate 23, and stably push the sheet into the space between the first polishing roller 8 and the second polishing roller 9 for double-sided polishing treatment, and then clamp the other end of the sheet through the rear clamping plate 23 to further ensure the stability of polishing and improve the polishing accuracy. At the same time, through the release of the sheet by the clamping plate 23, it is possible to control the sheet to return to the conveyor belt 4 smoothly again after the sheet is polished, so as to transfer the sheet out of the processing machine 1 through the conveyor belt 4.

[0060] Please refer to Figure 3 、 Figure 4 、 Figure 6 、 Figure 7The lifting guide mechanism includes a guide groove and a limit groove 205 provided on the support plate 2, the limit groove 205 is connected with the guide groove, a guide block 28 cooperating with the limit groove 205 is rotatably installed in the guide groove, and a limit assembly cooperating with the guide block 28 is arranged on the support sleeve 16, wherein the limit assembly includes a slot 17 provided on the side wall of the support sleeve 16, and a limit column 19 slidably connected with the slot 17 is arranged on the support rod 18, the limit column 19 can slide along the guide groove and cooperate with the guide block 28, and the limit column 19 is provided with a limit ring 1901 cooperating with the support plate 2.

[0061] Furthermore, there are also four sets of guiding grooves. Two sets of guiding grooves are symmetric about the left and right, and two sets of guiding grooves are symmetric about the front and back. Each set of guiding grooves can be divided into four sections, namely the first straight groove 201, the first inclined groove 202, the second straight groove 203, and the second inclined groove 204. The two ends of the first inclined groove 202 are respectively connected to one end of the first straight groove 201 and the second straight groove 203. The two ends of the second inclined groove 204 are respectively connected to the other end of the second straight groove 203 and the first straight groove 201. The guiding block 28 is located at the connection position of the second inclined groove 204 and the first straight groove 201. The limiting groove 205 is arranged in an arc-shaped fan shape. In the initial state, under the action of gravity, the guiding block 28 is connected to one end of the limiting groove 205 to block the second inclined groove 204. The limiting post 19 at the front end is located at the connection position of the first inclined groove 202 and the second straight groove 203, and the limiting post 19 at the rear end is located at the end of the stroke of the first straight groove 201 away from the first inclined groove 202. When the front clamping plate 23 clamps the sheet material, at this time, the front one-way lead screw 14 rotates and drives the second threaded sleeve 15 to move, thereby driving the support sleeve 16 and the support rod 18 to move synchronously. The support rod 18 also drives the limiting post 19 and the limiting ring 1901 to move. The limiting ring 1901 can slide along the surface of the supporting plate 2. Therefore, it can play a guiding role for the second threaded sleeve 15 to ensure that the second threaded sleeve 15 does not rotate with the one-way lead screw 14. The limiting post 19 will slide along the second straight groove 203. When the limiting post 19 disengages from the second straight groove 203 and enters the second inclined groove 204, the support rod 18 will move in a direction away from the support sleeve 16. When the limiting post 19 abuts against one side of the guiding block 28, the guiding block 28 will give way and rotate until the guiding block 28 abuts against the other end of the limiting groove 205. At this time, the guiding block 28 no longer blocks the second inclined groove 204. At this time, the limiting post 19 will disengage from the second inclined groove 204 and enter the first straight groove 201. The guiding block 28 will reset and block the second inclined groove 204 again. The sheet material in the clamping plate 23 just moves to the position where it cooperates with the first grinding roller 8 and the second grinding roller 9. The one-way lead screw 14 continues to rotate to push the sheet material into the space between the first grinding roller 8 and the second grinding roller 9 for double-sided grinding.

[0062] When the front end of the sheet passes through the first grinding roller 8 and the second grinding roller 9, the clamping plate 23 at the rear end can clamp the sheet. At the same time, the one-way screw 14 at the rear end rotates and keeps the same speed as the one-way screw 14 at the front end to control the clamping plate 23 at the rear end to move synchronously with the clamping plate 23 at the front end. The limiting column 19 at the rear end will slide along the first straight groove 201. When the grinding is completed, the limiting column 19 is still located in the first straight groove 201, and during the movement of the limiting column 19, the guide block 28 moves the second inclined groove 204. Blocking, therefore, can ensure that the limit column 19 will not separate from the first straight groove 201. When the limit column 19 separates from the first straight groove 201 and enters the first inclined groove 202, the support rod 18 will move toward the support sleeve 16. When the limit column 19 moves to the connection position between the first inclined groove 202 and the second straight groove 203, the distance between the clamping plate 23 and the conveyor belt 4 is the smallest. At this time, the clamping plate 23 can be controlled to separate from the sheet, and the sheet will fall onto the conveyor belt 4 again. Under the action of the conveyor belt 4, the sheet is controlled to move outside the processing machine 1.

[0063] See also Figures 3 - 6 , Figure 8 The spacing control component includes a double-headed cylinder 25 installed on the receiving plate 20, and the double-headed cylinder 25 is provided with a symmetrically arranged push plate 26, and the push plate 26 is hinged with a symmetrically arranged connecting rod 27; it also includes a movable rod 24 installed on the second sliding block 22, and the movable rod 24 is hinged to the connecting rod 27.

[0064] To go further, in the initial state, under the action of the double-headed cylinder 25, the distance between the two push plates 26 is maximized, so that the distance between the two second sliding blocks 22 is maximized through the connecting rod 27 and the movable rod 24, so that the two clamping plates 23 are at the end of the stroke in the direction of moving away from each other. When the sheet needs to be clamped, under the action of the double-headed cylinder 25, the two push plates 26 are controlled to move in the direction of approaching each other, thereby driving the connecting rod 27 to move, so as to drive the two second sliding blocks 22 to slide along the second slide groove 2101 through the movable rod 24. Under the action of the second sliding block 22, the two clamping plates 23 are controlled to move in the direction of approaching each other until the clamping plates 23 abut against both sides of the sheet.

[0065] Preferably, the double-headed cylinder 25 can be used to synchronously control the two clamping plates 23 to move towards or away from each other so as to clamp sheets of different sizes. At the same time, it can also ensure that the central horizontal reference plane between the two clamping plates 23 remains unchanged during the adjustment process to ensure the optimal accuracy of subsequent grinding.

[0066] It should be noted that the grinding method in the present application is not limited to double-sided grinding. If only one of the motors 7 is started, single-sided grinding can also be achieved; that is, the device can be used for single-sided grinding and double-sided grinding.

[0067] In addition, the main purpose of polishing is to increase the surface roughness of the aerogel product, ultimately enhancing the surface peel strength of the product. Therefore, the means to achieve this are not limited to polishing, and the surface peel strength of the product can also be improved by brushing the surface of the aerogel with a brush. Therefore, the polishing roller in this application can be equivalently replaced by a brush roller.

[0068] Furthermore, this method can effectively increase the surface roughness of the aerogel sheet. Of course, the specific treatment methods are not limited to polishing. Sandpaper, brushes, non-woven fabrics, etc. can also be used to polish, brush, etc. the surface of the aerogel. Through the above treatments, the surface peel strength can be increased by about 50%.

[0069] The following is an illustration with data showing the change in the surface peel strength of the aerogel product after polishing and brushing treatment, as shown in Table 1 below:

[0070] Table 1 Surface Peel Strength of the Product Before and After Polishing or Brushing

[0071]

[0072] By comparing the peel strength before and after polishing in Table 1, it can be seen that the surface peel strength of the aerogel product treated by polishing or brushing with this processing method has been significantly improved. Thus, the product has the following advantages:

[0073] 1. Enhance the bonding strength: The treated aerogel surface is rougher, enabling better bonding with other materials and reducing the risk of delamination and detachment.

[0074] 2. Improve the surface adhesion: The improved surface adhesion makes the aerogel suitable for applications that require strong bonding with other materials, such as coatings, adhesives, or other composite materials.

[0075] 3. Increase the durability and reliability: The better bonding strength ensures that the aerogel product has higher durability and reliability under various environmental conditions.

[0076] 4. Expand the application fields with high requirements: It is applicable to fields with higher requirements for bonding performance, such as the electronics, automotive, and aerospace industries.

[0077] In addition, the present invention also proposes a method for processing an aerogel sheet using the above-described equipment, including the following steps:

[0078] Step 1: Place the aerogel sheet to be processed at the conveying device, and under the action of the conveying device, transport the aerogel sheet to the polishing device.

[0079] Step 2: Under the action of the grinding device, perform single-sided grinding or double-sided synchronous grinding on the aerogel sheet according to requirements;

[0080] Step 3: Through a vacuum adsorption device, absorb and process the impurities generated during the grinding of the aerogel sheet;

[0081] Step 4: After grinding is completed, under the action of the conveying device, convey the ground product to the on-line thickness measuring device to perform real-time detection on the size of the ground product.
