Description

Technical Field

[0001] The utility model relates to the technical field of optical adhesive production, in particular to an OCA optical adhesive anti-adhesion feeding device. Background Art

[0002] OCA optical adhesive is one of the important raw materials for touch screens. It is a double-sided adhesive tape without a base material, made by making optical acrylic adhesive without a base material, and then laminating a layer of release film on the upper and lower base layers. It is the best adhesive for touch screens. Its advantages are clarity, high light transmittance (total light transmittance>99%), high adhesion, high weather resistance, water resistance, high temperature resistance, UV resistance, controlled thickness, uniform spacing, and no yellowing, peeling or deterioration after long-term use.

[0003] After the OCA optical glue is produced, it needs to be packaged and unloaded. Since the OCA optical glue has a certain viscosity, the inner wall of the unloading device will stick to the OCA optical glue during the unloading process. If the OCA optical glue is not cleaned in time, it will dry on the inner wall of the unloading device, making subsequent cleaning more troublesome. Secondly, the internal structure of the existing unloading device is relatively complex, and these structures are also prone to adhesion to the OCA optical glue, which is also not conducive to subsequent cleaning. Therefore, the utility model proposes an anti-sticking unloading device for OCA optical glue. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an OCA optical adhesive anti-adhesion feeding device.

[0022] like Figure 1-Figure 3 As shown, it relates to an OCA optical adhesive anti-sticking feeding device, including a barrel 1, the top of the barrel 1 is open-end design, and a feed pipe 2 is fixed to the top of the side wall of the barrel 1, and a discharge pipe 3 is fixedly connected to the bottom wall of the barrel 1. A push plate 4 that can move up and down is provided inside the barrel 1, and the side of the push plate 4 is in contact with the inner wall of the barrel 1, a bent rod 5 is provided above the push plate 4, and an internal threaded sleeve 51 is sleeved on the bottom end surface of the bent rod 5, a screw 41 for connecting the internal threaded sleeve 51 is fixed on the upper surface of the push plate 4, and a lifting component 6 for driving the bent rod 5 to move is installed on the outer wall of the barrel 1.

[0024] The device can be fixedly installed via the mounting plate 9.

[0025] A first valve 21 is fixed in the middle of the feed pipe 2 , and a second valve 31 is fixed in the middle of the discharge pipe 3 .

[0026] Among them, the first valve 21 is used to control the opening and closing of the feed pipe 2, and the optical glue can enter the barrel 1 along the feed pipe 2; the second valve 31 can control the opening and closing of the discharge pipe 3, and when the push plate 4 descends inside the barrel 1, the optical glue inside the barrel 1 can be pushed out from the discharge pipe 3.

[0027] An electric heating plate 7 is fixedly mounted on the outer wall of the barrel 1 .

[0028] The optical adhesive in the barrel 1 can be heated by the electric heating plate 7 to prevent the optical adhesive from solidifying inside the barrel 1 .

[0029] A circular hole is formed at the top of the internal threaded sleeve 51, and the bottom end of the bent rod 5 passes through the circular hole and is slidably connected to the circular hole. A baffle 52 is fixedly connected to the bottom end of the bent rod 5, and the size of the baffle 52 is larger than the circular hole. The internal threaded sleeve 51 is rotatably connected to the surface of the screw rod 41.

[0030] The internal thread sleeve 51 can slide and rotate along the bottom of the curved rod 5, so the internal thread sleeve 51 can be screwed to the surface of the screw rod 41, thereby achieving a fixed connection between the curved rod 5 and the push plate 4. The baffle 52 can prevent the internal thread sleeve 51 from being separated from the curved rod 5. By unscrewing the internal thread sleeve 51 from the surface of the screw rod 41, the push plate 4 and the curved rod 5 can be separated.

[0031] A square groove 42 is formed at the top of the screw rod 41 , and an insertion rod 53 is fixed to the lower surface of the baffle 52 , and the insertion rod 53 is clamped in the square groove 42 .

[0032] When the push plate 4 is installed at the bottom of the curved rod 5, the insert rod 53 can be inserted into the square groove 42, which can play a positioning role in the installation and prevent the push plate 4 and the bottom end of the curved rod 5 from rotating relative to each other.

A vertical strip opening 63 is opened on the side of the vertical rail 61 close to the barrel 1. The top of the bending rod 5 passes through the strip opening 63 and is fixedly connected to the slider 62. A servo motor 64 is fixed to the bottom end of the vertical rail 61, and a screw rod 65 is fixedly connected to the top output end of the servo motor 64. The top end of the screw rod 65 extends to the inside of the vertical rail 61, and the screw rod 65 passes through the slider 62 and is threadedly connected to the slider 62.

[0034] The servo motor 64 drives the screw rod 65 to rotate, and the screw rod 65 drives the slider 62 to move up or down along the inner cavity of the vertical rail 61, thereby driving the bending rod 5 to move, and the push plate 4 at the bottom of the bending rod 5 will move synchronously with the bending rod 5 to realize the lifting and lowering of the push plate 4.

[0035] Working principle: Open the first valve 21 on the feed pipe 2, and the optical glue enters the barrel 1 along the feed pipe 2. When unloading, open the second valve 31, and then start the servo motor 64 to drive the bending rod 5 and the push plate 4 to descend, and the push plate 4 pushes the optical glue in the barrel 1 out of the discharge pipe 3. When cleaning, start the servo motor 64 to drive the bending rod 5 and the push plate 4 to rise until the push plate 4 is separated from the barrel 1, and then remove the push plate 4 from the bottom of the bending rod 5, and then the inside of the barrel 1 and the push plate 4 can be cleaned.
