Description

Technical Field

[0001] The invention belongs to the technical field of adhesive tape production, in particular to a Teflon adhesive tape coating curing device. Background Art

[0002] After back sealing, the wafer needs to be edged. In order to prevent the SiO2 film from being corroded by HF, an acid-proof tape is attached to the back of the wafer to protect the rest of the SiO2 film except for the excess SiO2 film on the chamfered edge from being corroded. During the attachment process, due to the pressure of about 2 kg, if there are hard particles or silicon slag on the attachment platform, pits or dark scratches will be formed on the front side of the wafer (i.e., the ML side), and crystal fracturing can be seen under a microscope. In order to improve this situation, a whole piece of Teflon tape is attached to the attachment platform for improvement. When there are hard particles such as silicon slag, they will be embedded in the softer Teflon tape, which has a certain protective effect on the wafer.

[0003] At present, when producing Teflon tape, curing of its coating is a key process step, which ensures the strong bond between the adhesive and the substrate of the tape and the final performance of the tape.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 4As shown, a Teflon tape coating curing device according to an embodiment of the present invention comprises a coater 1, wherein the coater 1 is formed of a plurality of support frames in an integrated manner, a storage chamber 2 is fixedly installed inside the coater 1, glue is stored inside the storage chamber 2, and the glue is made of raw materials such as adhesives, solvents, additives and thickeners mixed in proportion, a gluing cylinder 3 is rotatably arranged above the storage chamber 2, a winding cylinder 4 is rotatably arranged above the coater 1 and located on the side of the gluing cylinder 3, an ultraviolet curing cylinder 401 is arranged above the winding cylinder 4, a retention plate 5 is fixedly connected to the upper side wall of the storage chamber 2, a tensioning roller 101 is rotatably installed inside the coater 1; a Teflon tape substrate 103 is arranged inside the coater 1;

[0034] The Teflon tape substrate 103 passes around the surface of the tension roller 101 and passes between the glue-applying cylinder 3 and the winding cylinder 4, and finally surrounds the surface of the winding cylinder 4; a scraper 501 is slidably provided above the retention plate 5, and the scraper 501 can slide above the retention plate 5 and scrape the glue overflowing above the retention plate 5 into the storage chamber 2;

[0035] When working, the Teflon tape is generally coated with a backing material, that is, a Teflon tape substrate 103, by a coating machine during the production process. The coating machine evenly coats the glue on the backing material to form a layer of glue film. Specifically, the Teflon tape substrate 103 is passed around the outer surface of all the tensioning rollers 101 and passes between the glue cylinder 3 and the winding cylinder 4. At this time, the winding cylinder 4 and the glue cylinder 3 are controlled by an external controller, and the winding cylinder 4 and the glue cylinder 3 are rotated. Since the glue cylinder 3 is located above the storage chamber 2, the glue cylinder 3 will store the storage chamber 2 during the rotation process. The glue inside the chamber 2 is brought out and coated on the surface of the Teflon tape substrate 103 on the outer peripheral surface of the winding tube 4. Then, the Teflon tape coating can be cured by irradiating the ultraviolet curing tube 401 above the winding tube 4, which is convenient for the subsequent use of the Teflon tape. Due to the mutual pressure between the winding tube 4 and the glue cylinder 3, part of the glue will drip on the top of the retention plate 5. Under the movement of the scraper 501, the glue retained on the top of the retention plate 5 can be scraped to the inside of the storage chamber 2, thereby realizing the automatic processing function of the overflowed glue and avoiding the problem of glue overflowing and being difficult to handle outside.

[0036] It should be noted that the ultraviolet curing tube 401 utilizes ultraviolet rays (UV) to produce photochemical reactions such as radiation polymerization and radiation cross-linking in a very short time, which rapidly converts low molecular weight substances into high molecular weight products, and can quickly cure the glue.

[0037] It should also be noted that, in the embodiment of the present invention, the Teflon tape includes a Teflon tape substrate 103, a glue coating on its surface, and a release paper on the surface of the Teflon tape substrate 103. In the present invention, the cured glue coating is located on the outer side of the rolled Teflon tape substrate 103 to facilitate the subsequent process of rewinding the adhesive paper. Specifically, the release paper is adhered to the outer side of the Teflon tape substrate 103 with glue, and the rolled Teflon tape substrate 103 is reversely wound to obtain a rolled finished Teflon tape; the purpose of adhering the release paper is to utilize the feature that the material of the release paper is easy to cut, so that when the Teflon tape is used later, Teflon tapes of different sizes can be cut according to the size of the wafer attachment platform, so that Teflon tapes of different sizes can be attached to platforms of different sizes, thereby improving the wafer attachment platform.

[0038] like Figures 2 to 6 As shown, the two ends of the winding drum 4 are fixedly installed with a rotating shaft 6, one end of which is connected to the output end of the external driving motor, and the two ends of the tensioning roller 101 are installed with a rotating shaft 2 102, and the rotating shaft 1 6 and the rotating shaft 2 102 are connected by a belt 1 7; during operation, when the external driving motor drives the rotating shaft 1 6 and the winding drum 4 to rotate, the rotating shaft 1 6 will simultaneously drive the rotating shaft 2 102 to rotate through the belt 1 7, and the rotating shaft 2 102 will drive the tensioning roller 101 to rotate, so that under the rotation of the tensioning roller 101, the Teflon tape substrate 103 wrapped around its outer surface can be transported, and sufficient tensioning force of the Teflon tape substrate 103 can be ensured, and the operation is more convenient.

[0039] The outer surface of the second rotating shaft 102 is fixedly mounted with an arc-shaped push block 8, and both ends of the scraper 501 are mounted with extension frames 9. When the arc-shaped push block 8 rotates following the second rotating shaft 102, the arc-shaped end of the arc-shaped push block 8 will contact the side wall of the extension frame 9, and the side wall of the extension frame 9 is mounted with an elastic telescopic rod 10, and the end of the elastic telescopic rod 10 away from the extension frame 9 is connected to the inner wall of the applicator 1;

[0040] During operation, when the rotating shaft 1 6 drives the rotating shaft 2 102 to rotate through the belt 1 7, the rotating shaft 2 102 will simultaneously drive the arc-shaped push block 8 on its outer surface to rotate, and the arc-shaped push block 8 will contact the side wall of the extension frame 9 during the rotation process, so that the extension frame 9 is pressed by the arc-shaped push block 8 and moves a certain distance, and the extension frame 9 will drive the scraper 501 to move on the upper end surface of the retention plate 5, and then the scraper 501 will automatically scrape the fallen glue into the interior of the storage chamber 2, so as to achieve the effect of automatically processing the excess fallen glue and avoid manual cleaning by the staff;

[0041] It should be noted that the arc-shaped end of the arc-shaped push block 8 pushes the extension frame 9 and makes the extension frame 9 drive the scraper 501 to move a distance that matches the width of the retention plate 5, so as to ensure that the scraper 501 can completely scrape the glue on the top of the retention plate 5 into the interior of the storage chamber 2;

[0042] It should also be noted that the surface of the scraper 501 is covered with a polyethylene film. The polyethylene film has a small surface tension and poor wetting ability, and is not easy to adhere to the glue. This can prevent the glue from sticking to the surface of the scraper 501.

[0043] Baffles 11 are installed on both sides of the upper edge of the retention plate 5, the end of the extension frame 9 passes through the inside of the baffle 11, and the outer peripheral surface of the elastic telescopic rod 10 is sleeved with a telescopic spring 12;

[0044] During operation, when the extension frame 9 is moved by the pressure of the arc-shaped push block 8, the extension frame 9 will simultaneously squeeze the elastic telescopic rod 10 on the other side, so that the elastic telescopic rod 10 drives the telescopic spring 12 on its surface to contract. When the rotating shaft 2 102 drives the arc-shaped push block 8 away from the extension frame 9, the telescopic spring 12 in the contracted state recovers and drives the elastic telescopic rod 10, the extension frame 9 and the scraper 501 to return to their initial positions. This makes it convenient for the subsequent scraper 501 to move again along the upper direction of the retention plate 5 close to the storage chamber 2 and scrape the glue retained on it into the storage chamber 2.

[0045] A rectangular groove 111 adapted to the extension frame 9 is opened inside the baffle 11, and a ball is rotatably arranged at the contact position between the outer peripheral surface of the extension frame 9 and the groove wall of the rectangular groove 111. During operation, when the extension frame 9 moves, it will move under the limit of the rectangular groove 111 inside the baffle 11, and under the action of the baffles 11 on both sides, the glue can be prevented from overflowing from the surface of the retention plate 5. At the same time, under the action of the rectangular groove 111 and the ball on the surface of the extension frame 9, the scraper 501 can be moved along the same axis, thereby facilitating the removal of the glue on the surface of the retention plate 5.

[0046] like Figures 3 to 8As shown, two fixing frames 13 are installed inside the applicator 1 and outside the upper glue cylinder 3, the upper glue cylinder 3 is located between the two fixing frames 13, and a horizontal axis 131 is installed on the side wall of each fixing frame 13. A deflection frame 14 is rotatably arranged at the end of the horizontal axis 131. The upper glue cylinder 3 is rotatably arranged between the two deflection frames 14 through a rotating column. The rotating column at the end of the upper glue cylinder 3 is connected to the output end of the external motor, and a pressing unit is arranged on the side wall of the deflection frame 14, which is used to control the deflection frame 14; when working, when the Teflon tape When the substrate 103 is transferred from the surface of the tensioning roller 101 to between the glue coating cylinder 3 and the winding cylinder 4, since the glue coating cylinder 3 and the winding cylinder 4 are in contact, the glue on the surface of the glue coating cylinder 3 will be on the back of the Teflon tape substrate 103, and the coated Teflon tape will slowly be wound on the winding cylinder 4. Since the glue coating cylinder 3 is rotatably arranged between the two deflection frames 14, when the external driving motor drives the rotating column and the glue coating cylinder 3 to rotate, the glue inside the storage chamber 2 will be brought out, thereby facilitating the application of glue on the Teflon tape substrate 103 and facilitating the subsequent curing effect of the glue coating.

[0047] like Figures 4 to 8 As shown, the pressing unit includes a telescopic pressure rod 15 installed above the fixed frame 13, the top of the telescopic pressure rod 15 contacts the side wall of the deflection frame 14, and the outer surface of the telescopic pressure rod 15 is sleeved with a limit spring 16; during operation, when the winding cylinder 4 contacts the glue cylinder 3, the telescopic pressure rod 15 will press against the side wall of the deflection frame 14, and under the elastic force of the telescopic pressure rod 15 and the limit spring 16, the glue cylinder 3 can be tightly contacted with the winding cylinder 4, and as the amount of tape on the surface of the winding cylinder 4 increases, the pressure on the glue cylinder 3 by the winding cylinder 4 increases, and the glue cylinder 3 and the deflection frame 14 are subjected to pressure and rotate toward the side close to the telescopic pressure rod 15 with the horizontal axis 131 as the center. Afterwards, under the support of the compressed elastic force of the telescopic pressure rod 15 and the limit spring 16, the close contact between the glue cylinder 3 and the winding cylinder 4 can be ensured, which is convenient for gluing the Teflon tape substrate 103 and is also beneficial to the curing of the Teflon tape coating.

[0048] like Figures 5 to 9 As shown, a rotating shaft 17 is rotatably provided on the inner wall of the storage chamber 2, and a stirring blade 18 is fixedly installed on the outer circumference of the rotating shaft 17. The stirring blades 18 are provided in multiple groups and are equidistantly arranged on the outer circumference of the rotating shaft 17. A linkage unit is provided on the outer circumference of the rotating shaft 17, and the linkage unit is used to drive the rotating shaft 17 to rotate; during operation, when the rotating shaft 6 rotates, the rotating shaft 6 will simultaneously drive the rotating shaft 17 to rotate through the linkage unit, so that the rotating shaft 17 drives the stirring blades 18 to rotate, and the stirring blades 18 will stir the glue inside the storage chamber 2, thereby facilitating the coating of the glue.

[0049] like Figures 6 to 9As shown, the linkage unit includes a belt 19 wrapped around the outer circumference of the rotating shaft 6, and the other end of the belt 19 away from the rotating shaft 6 is wrapped around the outer circumference of the rotating shaft 17; through the rotation of the rotating shaft 6, the rotating shaft 6 will drive the rotating shaft 17 to rotate through the belt 19, thereby driving the stirring blade 18 to rotate at a certain speed, which is convenient for the coating of glue and the curing of the glue coating.

[0050] The side wall of the storage chamber 2 is provided with an opening cover, and the outer wall of the storage chamber 2 is installed with a heating wire. Such a design can facilitate the addition and molding of raw materials inside the storage chamber 2.

[0051] When working, the Teflon tape is generally coated with a backing material, that is, a Teflon tape substrate 103, by a coating machine during the production process. The coating machine evenly coats the glue on the backing material to form a layer of glue film. Specifically, the Teflon tape substrate 103 is passed around the outer surface of all the tensioning rollers 101 and passes between the glue cylinder 3 and the winding cylinder 4. At this time, the winding cylinder 4 and the glue cylinder 3 are controlled by an external controller, and the winding cylinder 4 and the glue cylinder 3 are rotated. Since the glue cylinder 3 is located above the storage chamber 2, the glue cylinder 3 will store the storage chamber 2 during the rotation process. The glue inside the chamber 2 is brought out and coated on the surface of the Teflon tape substrate 103 on the outer peripheral surface of the winding tube 4. Then, the Teflon tape coating can be cured by irradiation of the ultraviolet curing tube 401 above the winding tube 4, which is convenient for the subsequent use of the Teflon tape. Due to the mutual pressure between the winding tube 4 and the glue-applying tube 3, part of the glue will drip onto the top of the retention plate 5. Under the movement of the scraper 501, the glue retained on the top of the retention plate 5 can be scraped into the interior of the storage chamber 2, realizing the automatic processing function of the overflowed glue, avoiding the problem that the glue overflows and is difficult to process outside;

[0052] When the rotating shaft 106 drives the rotating shaft 2 102 to rotate through the belt 107, the rotating shaft 2 102 will simultaneously drive the arc-shaped push block 8 on its outer surface to rotate. The arc-shaped push block 8 will contact the side wall of the extension frame 9 during the rotation, so that the extension frame 9 is pressed by the arc-shaped push block 8 and moves a certain distance, and the extension frame 9 will drive the scraper 501 to move on the upper end surface of the retention plate 5, and then the scraper 501 will automatically scrape the fallen glue into the interior of the storage chamber 2, so as to achieve the effect of automatically processing the excess fallen glue and avoid manual cleaning by the staff; when the extension frame 9 is pressed, the scraper 501 will automatically scrape the fallen glue into the storage chamber 2, so as to automatically process the excess fallen glue and avoid manual cleaning by the staff; when the extension frame 9 is pressed, the scraper 501 will automatically scrape the fallen glue into the storage chamber 2, so as to ... When the extension frame 9 is moved by the pressure of the arc-shaped push block 8, the extension frame 9 will squeeze the elastic telescopic rod 10 on the other side at the same time, so that the elastic telescopic rod 10 drives the telescopic spring 12 on its surface to contract. When the rotating shaft 102 drives the arc-shaped push block 8 away from the extension frame 9, the telescopic spring 12 in the contracted state recovers and drives the elastic telescopic rod 10, the extension frame 9 and the scraper 501 to recover to the initial position, so that it is convenient for the subsequent scraper 501 to move again along the upper direction of the retention plate 5 close to the storage chamber 2, and scrape the glue retained on it into the storage chamber 2;

[0053] When the Teflon tape substrate 103 is transferred from the surface of the tensioning roller 101 to between the glue-applying cylinder 3 and the winding cylinder 4, since the glue-applying cylinder 3 and the winding cylinder 4 are in contact, the glue on the surface of the glue-applying cylinder 3 will be on the back of the Teflon tape substrate 103, and the coated Teflon tape will slowly be wound on the winding cylinder 4. Since the glue-applying cylinder 3 is rotatably arranged between the two deflection frames 14, when the external driving motor drives the rotating column and the glue-applying cylinder 3 to rotate, the glue inside the storage chamber 2 will be brought out, thereby facilitating the application of the glue on the Teflon tape substrate 103 and facilitating the subsequent curing effect of the glue coating.

[0054] When the winding cylinder 4 is in contact with the glue cylinder 3, the telescopic pressure rod 15 will press against the side wall of the deflection frame 14, and under the elastic force of the telescopic pressure rod 15 and the limit spring 16, the glue cylinder 3 can be in close contact with the winding cylinder 4, and as the amount of tape on the surface of the winding cylinder 4 increases, the pressure on the glue cylinder 3 by the winding cylinder 4 increases, and the glue cylinder 3 and the deflection frame 14 will be rotated toward the side close to the telescopic pressure rod 15 with the horizontal axis 131 as the center under pressure. Then, under the support of the compressed elastic force of the telescopic pressure rod 15 and the limit spring 16, the close contact between the glue cylinder 3 and the winding cylinder 4 can be ensured, which is convenient for the coating of the Teflon tape substrate 103 and is also beneficial to the curing of the Teflon tape coating. When the rotating shaft 6 rotates, the rotating shaft 6 will simultaneously drive the rotating shaft 17 to rotate through the linkage unit, so that the rotating shaft 17 drives the stirring blade 18 to rotate, and the stirring blade 18 will stir the glue inside the storage chamber 2, thereby facilitating the coating of the glue.
