Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating device technology, and in particular to a coating device for PI resin substrate. Background Technology
[0002] The PI resin substrate coating device is an automated equipment specifically designed to uniformly coat the surface of various substrates with PI resin coatings. Its core function is to form a PI coating that meets the requirements of thickness, flatness, adhesion, etc., by precisely controlling the coating process, so as to endow the substrate with specific functions.
[0003] When coating a substrate surface with PI resin using a coating device, some PI resin particles will contain air, which will form tiny bubbles on the substrate surface. These bubbles will cause the PI resin coating to be incomplete, increase the defect rate of the coating, and thus reduce the functionality of the coating. Utility Model Content
[0004] This invention provides a PI resin substrate coating device to address the problem that some PI resin particles contain air, which can form tiny bubbles on the surface of the substrate. These bubbles can lead to incomplete PI resin coating and reduce the functionality of the coating.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a PI resin substrate coating device, comprising an operating table, with supports installed at both ends of the operating table, and a roll rotatably mounted on the inner wall of the supports. A driving component is provided on one side of one of the supports, which can drive the roll to rotate. Movable frames are slidably mounted on both sides of the operating table, and coating nozzles are slidably mounted on the inner wall of the movable frames. The top of the two supports is provided with the same auxiliary device, which, by setting two auxiliary plates that can tap the top of the supports, causes the substrate on the two rolls to vibrate and eliminate air bubbles.
[0006] The effect achieved by the above components is as follows: by setting two auxiliary plates and adjusting the auxiliary plates, the two auxiliary plates will strike the top of the two supports respectively. Since the substrate is in a taut state on the two rolls, the vibration generated by the auxiliary plates striking the supports will be transmitted to the substrate, causing the substrate to vibrate, which is conducive to the elimination of micro bubbles, reducing the defect rate of the coating, and ensuring the functionality of the coating.
[0007] Preferably, the auxiliary device includes two auxiliary plates, which are disposed on the top of the support. A round rod is symmetrically and slidably installed on one side of each auxiliary plate. The outer surface of the round rod is slidably installed on one side of the support. The same connecting plate is fixedly installed on one side of both auxiliary plates. A rope is installed in the middle of the bottom of the connecting plate and is slidably inserted into one side of the operating table.
[0008] The effect achieved by the above components is as follows: pulling the rope causes the connecting plate to move downwards, and the connecting plate causes the auxiliary plate to move synchronously until the auxiliary plate hits the top of the bracket. This causes the substrate on the two drums to vibrate, thereby achieving the purpose of defoaming.
[0009] Preferably, a spring is fitted on the outer surface of the round rod, one end of the spring is fixedly installed on one side of the bottom of the auxiliary plate, and the other end of the spring is fixedly installed on one side of the bracket.
[0010] The effect achieved by the above components is as follows: by setting a spring, when the auxiliary plate moves downward under the action of the rope, the auxiliary plate will squeeze the spring, causing the spring to deform. At the same time, when the force applied to the rope is removed, the spring will reset and drive the auxiliary plate away from the support, causing the rope to slide upward, thus facilitating the repeated operation of the auxiliary plate.
[0011] Preferably, a circular block is fixedly installed at one end of the circular rod, and the outer diameter of the circular block is larger than the outer diameter of the circular rod.
[0012] The effect achieved by the above components is that by setting up a circular block, one end of the circular rod can be blocked, which helps to prevent the circular rod from detaching from the inner wall of the auxiliary plate due to misoperation.
[0013] Preferably, a silicone plate is installed on the side of the auxiliary plate near the bracket.
[0014] The effect achieved by the above components is as follows: by setting a silicone plate to replace the auxiliary plate on one side and abutting against the top of the bracket, the top of the bracket can be protected to a certain extent, which helps to prevent damage to the bracket when the auxiliary plate is repeatedly hit.
[0015] Preferably, rectangular rods are symmetrically installed on the bottom of the connecting plate, and auxiliary blocks are symmetrically installed on one side of the operating table. The rectangular rods are slidably installed on the inner wall of the auxiliary blocks, and bolts are threaded into the inner wall of the auxiliary blocks.
[0016] The effect achieved by the above components is as follows: when the auxiliary plate and the connecting plate move in the vertical direction, they will drive the rectangular rod to slide synchronously on the inner wall of the auxiliary block. Then, by rotating the bolt, one end of the bolt abuts against one side of the rectangular rod, and the bolt can fix the position of the auxiliary plate. This helps to prevent the auxiliary plate from hitting the support under the action of external force during the coating of PI resin, which would have an adverse effect on the coating process of the substrate.
[0017] Preferably, a rubber strip is adhered to the inner wall of one side of the rectangular rod, and the bolt is located on one side of the rubber strip.
[0018] The effect achieved by the above components is that by setting the rubber strip, one side of the rectangular rod can be replaced to abut against one end of the bolt, and the friction between the bolt and the rectangular rod can be increased, making the bolt more securely fixed to the rectangular rod.
[0019] Preferably, a handle is fixedly installed at one end of the rope, and the outer surface of the handle is uniformly provided with grooves.
[0020] The effect achieved by the above components is as follows: by setting up the grip, pulling the grip can drive the rope to move synchronously, and the groove on the outer surface of the grip can increase the friction of the grip, so as to have an anti-slip effect when adjusting the rope by holding the grip.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, two auxiliary plates are set and adjusted so that they strike the tops of the two supports respectively. Since the substrate is taut on the two rolls, the vibration generated by the auxiliary plates striking the supports is transmitted to the substrate, causing the substrate to vibrate. This helps to eliminate micro-bubbles, reduce the defect rate of the coating, and ensure the functionality of the coating. Attached Figure Description

[0028] Example 1, referring to Figures 1-3As shown, this embodiment discloses a PI resin substrate coating device, including an operating table 1. Supports 2 are mounted at both ends of the operating table 1. A roll 3 is rotatably mounted on the inner wall of each support 2. A drive assembly 4 is provided on one side of one of the supports 2, which can drive the roll 3 to rotate (the drive assembly 4 can be a motor mounted on the support 2, connected to one of the rolls 3 via a reducer, and powered by a power supply module to drive the roll 3 to rotate; since the motor drive module is a conventional technology, it will not be described in detail here). Movable frames 5 are slidably mounted on both sides of the operating table 1, and coating materials are slidably mounted on the inner wall of the movable frames 5. The nozzle 6 (the model of the coating nozzle 6 can be MSK-AFA-SD300) has the same auxiliary device 7 on the top of the two supports 2. The auxiliary device 7 has two auxiliary plates 71 that can tap the top of the support 2, causing the substrate on the two rolls 3 to vibrate and eliminate air bubbles. By setting the two auxiliary plates 71 and adjusting the auxiliary plates 71, the two auxiliary plates 71 tap the top of the two supports 2 respectively. Since the substrate is in a taut state on the two rolls 3, the vibration generated by the tapping of the support 2 by the auxiliary plates 71 will be transmitted to the substrate, causing the substrate to vibrate, which is conducive to the elimination of micro air bubbles, reducing the defect rate of the coating, and ensuring the functionality of the coating.
[0029] Reference Figure 2 and Figure 3 As shown, the auxiliary device 7 includes two auxiliary plates 71, which are mounted on the top of the support 2. A round rod 75 is symmetrically slidably mounted on one side of each auxiliary plate 71, and the outer surface of the round rod 75 is slidably mounted on one side of the support 2. A common connecting plate 72 is fixedly mounted on one side of each of the two auxiliary plates 71. A rope 73 is mounted in the middle of the bottom of the connecting plate 72 and is slidably inserted into one side of the operating table 1. Pulling the rope 73 causes the connecting plate 72 to move downwards, which in turn causes the auxiliary plates 71 to move synchronously until the auxiliary plates 71 strike the top of the support 2. This causes the bases on the two drums 3 to... The material vibrates, thus achieving the purpose of defoaming; a spring 74 is sleeved on the outer surface of the round rod 75. One end of the spring 74 is fixedly installed on one side of the bottom of the auxiliary plate 71, and the other end of the spring 74 is fixedly installed on one side of the bracket 2. By setting the spring 74, when the auxiliary plate 71 moves downward under the action of the rope 73, the auxiliary plate 71 will squeeze the spring 74, causing the spring 74 to deform. At the same time, when the force applied to the rope 73 is removed, the spring 74 will reset and drive the auxiliary plate 71 away from the bracket 2, and drive the rope 73 to slide upward, thus facilitating the repeated operation of the auxiliary plate 71.
[0030] Reference Figure 2 and Figure 3As shown, a round block 712 is fixedly installed at one end of the round rod 75. The outer diameter of the round block 712 is larger than the outer diameter of the round rod 75. By setting the round block 712, one end of the round rod 75 can be blocked, which helps to prevent the round rod 75 from detaching from the inner wall of the auxiliary plate 71 due to misoperation. A silicone plate 76 is installed on the side of the auxiliary plate 71 near the bracket 2. By setting the silicone plate 76, it replaces one side of the auxiliary plate 71 and abuts against the top of the bracket 2, which can play a certain protective role for the top of the bracket 2 and helps to prevent the bracket 2 from being damaged when the auxiliary plate 71 repeatedly hits the bracket 2.
[0031] Reference Figure 2 and Figure 4 As shown, rectangular rods 77 are symmetrically installed on the bottom of the connecting plate 72, and auxiliary blocks 78 are symmetrically installed on one side of the operating table 1. The rectangular rods 77 are slidably installed on the inner wall of the auxiliary blocks 78. Bolts 79 are threaded into the inner wall of the auxiliary blocks 78. When the auxiliary plate 71 and the connecting plate 72 move vertically, the rectangular rods 77 will slide synchronously on the inner wall of the auxiliary blocks 78. Then, the bolts 79 are rotated so that one end of the bolts 79 abuts against one side of the rectangular rods 77. The bolts 79 can fix the position of the auxiliary plate 71, which helps to prevent the auxiliary plate 71 from hitting the bracket 2 under the action of external force during the coating of PI resin, thus avoiding adverse effects on the coating process of the substrate. A rubber strip 710 is bonded to the inner wall of one side of the rectangular rods 77. The bolts 79 are set on one side of the rubber strip 710. By setting the rubber strip 710, one side of the rectangular rods 77 can be replaced to abut against one end of the bolts 79, and the friction between the bolts 79 and the rectangular rods 77 can be increased, making the bolts 79 more firmly fixed to the rectangular rods 77.
[0032] Reference Figure 2 As shown, a handle 711 is fixedly installed at one end of the rope 73. The outer surface of the handle 711 is evenly provided with grooves. By setting the handle 711, pulling the handle 711 can drive the rope 73 to move synchronously. At the same time, the grooves on the outer surface of the handle 711 can increase the friction of the handle 711, so that the rope 73 can be adjusted by using the handle 711.
[0033] Working principle: By pulling the rope 73 with the handle 711, the rope 73 causes the connecting plate 72 to move downwards. The connecting plate 72 then causes the auxiliary plate 71 to move synchronously. During the downward movement of the auxiliary plate 71, it compresses the spring 74, causing the spring 74 to deform until the silicone plate 76 on one side of the auxiliary plate 71 hits the top of the bracket 2. At this point, the force applied to the handle 711 is gradually released. The spring 74, no longer compressed by the auxiliary plate 71, will reset and cause the auxiliary plate 71 to automatically move away from the bracket 2. This also causes the rope 73 to slide upwards. Repeating this operation multiple times will cause the support to vibrate continuously. Simultaneously, due to the substrate... The two rollers 3 are in a taut state. The vibration generated by the impact of the auxiliary plate 71 on the support 2 is transmitted to the substrate, causing the substrate to vibrate, which is beneficial to the elimination of micro-bubbles. When the auxiliary plate 71 and the connecting plate 72 move in the vertical direction, they will drive the rectangular rod 77 to slide synchronously on the inner wall of the auxiliary block 78. Then, the bolt 79 is rotated so that one end of the bolt 79 abuts against the rubber strip 710 on one side of the rectangular rod 77. The bolt 79 can fix the position of the auxiliary plate 71, which helps to prevent the auxiliary plate 71 from hitting the support 2 under the action of external force during the coating of PI resin, thus avoiding adverse effects on the coating process of the substrate.
