Description

Technical Field

[0001] The utility model relates to the technical field of coating, in particular to an automatic coating device. Background Art

[0002] The existing experimental coating machine, on the one hand, fixes the substrate through vacuum adsorption technology to ensure the stability and flatness of the substrate during the coating process; on the other hand, the coating liquid is directly coated on the substrate to be coated.

[0003] When vacuum adsorption is used, if the substrate is too large, the adsorption area is too large, or the substrate is initially unevenly placed and does not fit neatly against the adsorption table, wrinkles may easily form on the substrate after vacuum adsorption is activated, preventing it from being flattened in one go and requiring manual smoothing a second time, which is a cumbersome operation. When the coating liquid is applied directly, the amount of coating liquid is difficult to control, especially when the coating thickness varies. Specifically, if too much coating liquid is applied, it can easily overflow from the substrate to be coated onto the adsorption table, contaminating the adsorption table and hindering subsequent coating, as well as making cleanup difficult. If too little coating liquid is applied, coating cannot be completed, resulting in uneven coating and poor results. Utility Model Content

[0032] like Figure 1-7 As shown, an embodiment of an automatic coating device is characterized by comprising:

[0033] The adsorption platform 1 is provided with a plurality of first adsorption holes 11;

[0034] The adsorption mechanism is connected to the adsorption platform 1 and vacuumizes the first adsorption hole 11;

[0035] The base 3 is connected to the adsorption platform 1 and supports the adsorption platform 1;

[0036] The guide channel 4 is provided on the base 3 and is provided on both sides of the adsorption platform 1 along the width direction of the adsorption platform 1;

[0037] The push rod assembly 5 includes a push rod 51 and two support columns 52. The push rod 51 is mounted on the two support columns 52. The support columns 52 are arranged in the guide channel 4 and move along the guide channel 4. The push rod 51 is arranged above the adsorption platform 1 and moves synchronously with the support columns 52.

[0038] The scraper plate 6 is connected to the push rod 51 and is arranged above the substrate to be coated;

[0039] The coating preparation mold 7 is a "mouth"-shaped structure, comprising two first side walls 71 and two second side walls 72 disposed opposite each other. The outer surface of one of the two first side walls 71 abuts against the push rod 51. The lower surface of the second side wall 72 abuts against the substrate to be coated, and a gap is left between the lower surface of the first side wall 71 and the substrate to be coated. The coating preparation mold 7 moves synchronously with the push rod 51.

[0040] The driving mechanism 8 is fixedly disposed on the base 3 , connected to the support column 52 and drives the support column 52 to reciprocate along the guide channel 4 .

[0041] The adsorption platform 1 and the adsorption mechanism cooperate to adsorb the substrate to be coated onto the surface of the adsorption platform 1 to fix the substrate to be coated, thereby ensuring the stability of the substrate to be coated during the coating process and preventing displacement.

[0042] The design of the coating preparation mold 7 is as follows: first, it is pressed onto the substrate to be coated by its own gravity; second, it is set in a "mouth" shape to form a hollow inner cavity. After being pressed onto the substrate to be coated, the coating liquid is injected into the hollow inner cavity to store the coating liquid, ensuring that the coating liquid is sufficient while preventing the coating liquid from overflowing and contaminating areas such as the adsorption platform 1; third, a gap is left between the lower surface of the first side wall 71 of the coating preparation mold 7 and the substrate to be coated, and the gap realizes slit coating (specifically, during the movement of the coating preparation mold 7, the coating liquid stored in the hollow inner cavity is left on the surface of the substrate to be coated through the gap).

[0043] The push rod 51 cooperates with the coating preparation mold 7. When the substrate to be coated is fixed, the push rod 51 pushes the coating preparation mold 7 to move on the substrate to be coated to achieve coating. The high precision of the coating preparation mold 7 leads to high coating accuracy, uniform coating, and good coating effect. Furthermore, the drive mechanism 8 drives the push rod 51 along the guide channel 4 to achieve coating.

[0044] In this embodiment, the length direction of the guide channel 4 is the same as the length direction of the adsorption platform 1 .

[0045] Before coating, the scraper plate 6 is placed in contact with the substrate to be coated and, driven by the drive mechanism 8, moves synchronously with the push rod 51 along the length of the adsorption platform 1 to eliminate wrinkles on the substrate surface. Specifically, the substrate to be coated is placed on the surface of the adsorption platform 1, and the adsorption mechanism is activated to attract the substrate to the surface of the adsorption platform 1. If wrinkles are formed during adsorption, the drive assembly is activated to move the scraper plate 6 to smooth the substrate surface.

[0046] like Figure 1-6 As shown, in another preferred embodiment, along the length direction of the adsorption platform 1, the adsorption platform 1 includes a low vacuum adsorption area 12 and a high vacuum adsorption area 13; the adsorption mechanism includes a first adsorption mechanism 21 and a second adsorption mechanism 22; the first adsorption mechanism 21 is connected to the high vacuum adsorption area 13 to fix the substrate to be coated on the adsorption platform 1; the second adsorption mechanism 22 is connected to the low vacuum adsorption area 12 to cooperate with the scraper plate 6 for scraping.

[0047] The adsorption platform 1 includes two adsorption areas that are partitioned. The two adsorption areas are activated successively, and the substrate to be coated is gradually partitioned to fit the adsorption platform 1. The small single adsorption area facilitates adjustment of the substrate to be coated to eliminate wrinkles on the surface of the substrate to be coated.

[0048] Furthermore, the adsorption platform 1 cooperates with the scraper plate 6 to keep the substrate to be coated on the adsorption platform 1 in an adsorption state. When the scraper plate 6 is started, the substrate to be coated is not easily displaced; further, the adsorption force of the high vacuum adsorption area 13 is strong, and the fixing effect of the substrate to be coated is better.

[0049] Furthermore, when in use, the high vacuum adsorption area 13 can be fixed first to preliminarily fix the substrate to be coated; keep the high vacuum adsorption area 13 working, and then start the scraping plate 6 to ensure that the substrate to be coated is flat on the surface of the adsorption table 1, and the substrate to be coated fits the surface of the adsorption table 1 without a gap, eliminates some air, and closes the scraping plate 6 after completion; finally, start the low vacuum adsorption area 12. At this time, since the scraping operation has been performed before, there are fewer wrinkles during adsorption. If there are still wrinkles, start the scraping plate 6 again to perform the scraping operation.

[0050] like Figure 1 and Figure 7 As shown, in another preferred embodiment, the scraping plate 6 is fixedly connected to the push rod 51 and moves synchronously with the push rod 51; a medium vacuum adsorption area 61 is provided on the side of the scraping plate 6 facing the adsorption platform 1, and a plurality of second adsorption holes 62 are provided in the medium vacuum adsorption area 61; the scraping plate 6 is connected to the third adsorption mechanism 23 and the second adsorption holes 62 are vacuumed through the third adsorption mechanism 23.

[0051] By providing the vacuum adsorption area 61 on the scraping plate 6, wrinkles on the substrate to be coated are eliminated.

[0052] Specifically, the scraper plate 6 moves along the guide channel 4 under the action of the driving mechanism 8, and also moves above the substrate to be coated. The opposite sides of the substrate to be coated are simultaneously subjected to the suction of the adsorption platform 1 and the suction of the scraper plate 6; when the scraper plate 6 passes through the high vacuum adsorption area 13, since the adsorption force of the medium vacuum adsorption area 61 of the scraper plate 6 is less than the adsorption force of the high vacuum adsorption area 13, the substrate to be coated in the high vacuum adsorption area 13 does not shift; when the scraper plate 6 passes through the low vacuum adsorption area 12, since the adsorption force of the medium vacuum adsorption area 61 of the scraper plate 6 is greater than the adsorption force of the low vacuum adsorption area 12, the scraper plate 6 adsorbs the substrate to be coated and stretches the substrate to be coated during the movement. After the scraper plate 6 passes, the low vacuum adsorption area 12 adsorbs the stretched substrate to be coated on the table surface of the adsorption platform 1, thereby completing the scraping operation of the substrate to be coated.

[0053] The scraper plate 6 and the push rod 51 are fixedly connected by bolts.

[0054] Furthermore, according to the adsorption strength from large to small, the high vacuum adsorption area 13 is larger than the medium vacuum adsorption area 61 , which is larger than the low vacuum adsorption area 12 .

[0055] like Figure 1-2As shown, in another preferred embodiment, the support column 52 includes a fixed section 521 and a guide section 522, the push rod 51 is arranged in the fixed section 521, and the push rod 51 is clamped between the locking member 53 and the guide section 522 along the vertical direction through a locking member 53 threadedly connected to the fixed section 521.

[0056] The support rod and the locking member 53 cooperate to fix the push rod 51 in the vertical direction; in this embodiment, the fixing section 521 is provided with a thread, the locking member 53 is a nut, and the locking member 53 is threadedly connected to the fixing section 521 to fix the push rod 51.

[0057] The push rod 51 is clamped between the two support columns 52, and the two support columns 52 limit the push rod 51 along the width direction of the adsorption platform 1; the push rod 51 and the support rods are matched with each other to achieve the limit of the push rod 51 along the length direction of the adsorption platform 1.

[0058] like Figure 1-2 As shown, in another preferred embodiment, the support column 52 is also connected to a height adjustment component 9, which includes a fixed seat 91 and a height adjusting member 92 connected to the fixed seat 91. The fixed seat 91 is fixedly connected to the support column 52, and a guide hole 911 is provided on the fixed seat 91. The height adjusting member 92 is threadedly connected to the support column 52 through the guide hole 911 and moves in the vertical direction; one end of the height adjusting member 92 abuts against the lower surface of the support column 52 to make the support column 52 and the height adjusting member 92 move synchronously.

[0059] The height of the push rod 51 is adjusted by the height adjusting member 92 to adapt to the scraping operation of substrates to be coated with different thicknesses.

[0060] like Figure 1 and Figure 4 As shown, in another preferred embodiment, a waste collection tray 10 is provided at at least one end of the adsorption platform 1 along the length direction of the adsorption platform 1 .

[0061] The excess coating liquid is collected by the waste collection tray 10 ; further, along the length direction of the adsorption platform 1 , the waste collection tray 10 is disposed at one end of the adsorption platform 1 away from the high vacuum adsorption area 13 .

[0062] like Figure 1-7 As shown, the operating steps of the utility model are as follows:

[0063] Step 1: Lay the substrate to be coated flat on the adsorption area of ​​the adsorption platform 1;

[0064] Step 2: Fix the scraper plate 6 to the push plate, place the push plate on the support column 52, adjust the height adjustment member 92 according to the thickness of the substrate to be coated so that the scraper plate 6 is located above the substrate to be coated, and lock the push plate with the locking member 53;

[0065] Step 3: First start the first adsorption mechanism 21, the high vacuum adsorption area 13 works, and manually scrape it flat according to the adsorption situation; then start the second adsorption mechanism 22, the low vacuum adsorption area 12 works;

[0066] Step 4: Start the driving mechanism 8, move the scraper plate 6 to the top of the substrate to be coated, and pause the movement of the driving mechanism 8;

[0067] Step 5: Start the third adsorption mechanism 23 and continue to turn on the drive mechanism 8. The scraping plate 6 moves along the length direction of the adsorption platform 1 from one end of the substrate to be coated to the other end of the substrate to be coated to complete the scraping operation. Close the third adsorption mechanism 23 and the drive mechanism 8.

[0068] Step 6: Start the driving mechanism 8 so that the push rod 51 is located directly above one end of the substrate to be coated, and then close the driving mechanism 8; place the coating preparation mold 7 on one end of the substrate to be coated so that the first side wall 71 of the coating preparation mold 7 abuts against the push rod 51;

[0069] Step seven: injecting the coating liquid into the hollow inner cavity of the coating preparation mold 7; starting the driving mechanism 8, the coating preparation mold 7 moves along the guide groove and forms a coating layer on the substrate at the same time.

[0070] Step 8: After the coating preparation mold 7 moves to the other end of the substrate, the driving mechanism 8 is turned off, and the excess coating liquid will flow into the waste collection tray 10; the above completes the entire coating process.

[0071] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
