Description

Technical Field

[0001] The utility model relates to the technical field of LCM production and processing, in particular to a glue-sealing device for LCM. Background Technique

[0002] LCM refers to a component assembled by liquid crystal display devices, connectors, peripheral circuits such as control and drive, PCB circuit boards, backlights and structural parts. Such modules are widely used in various electronic devices, such as smart phones, tablet computers and televisions. When LCM is produced and processed, glue-sealing is required, so glue-sealing equipment for LCM is needed.

[0003] When the existing LCM glue-sealing device is used for glue-sealing, the front opening area of the device is relatively large and there is no corresponding shielding structure. Therefore, when glue-sealing, external substances are likely to adhere to the upper part, which will affect the overall glue-sealing quality.

[0004] Therefore, a glue-sealing device for LCM is proposed to solve the above technical problems. Content of the Utility Model

[0005] The utility model discloses a glue-sealing device for LCM, aiming to solve the technical problem that when the existing LCM glue-sealing device is used for glue-sealing, the front opening area of the device is relatively large and there is no corresponding shielding structure. Therefore, when glue-sealing, external substances are likely to adhere to the upper part, which will affect the overall glue-sealing quality.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0031] Refer to Figures 1 - 5, A potting device for an LCM, comprising a potting belt conveyor 1 and a potting machine case 6. The potting belt conveyor 1 is installed and connected to the middle position at the upper end of the potting machine case 6. An LCM workpiece 8 is placed on the conveyor belt of the potting belt conveyor 1. Thus, the potting belt conveyor 1 can drive the LCM workpiece 8 for conveying and potting. A protective shielding frame 4 is installed on the potting machine case 6 outside the potting belt conveyor 1. Through the protective shielding frame 4, effective shielding and protection can be achieved to prevent external substances from entering the inside. During maintenance, the protective shielding frame 4 can be opened for maintenance. A conveying slot hole 7 is provided between the protective shielding frame 4 and the potting machine case 6 to enable corresponding conveying for use. A coating conveying mechanism 3 is installed at the inner top end of the potting machine case 6. A glue coating mechanism 5 is installed at the lower end of the coating conveying mechanism 3. A potting glue storage mechanism 2 is installed on the potting machine case 6 at the upper end of the coating conveying mechanism 3. Thus, the coating conveying mechanism 3 can extract the glue from the potting glue storage mechanism 2 and convey it to the glue coating mechanism 5. In this way, the glue coating mechanism 5 can pot the LCM workpiece 8 below;

[0032] The protective shielding frame 4 includes a transparent viewing plate 41, a lead screw body 42, a lead screw motor 43, a lead screw slider 44, a movable partition 45, and a concave frame 46. The concave frame 46 is fixedly connected to the potting machine case 6, so that the concave frame 46 can be installed and placed. The movable partition 45 is sleeved in the front groove of the concave frame 46, so that the movable partition 45 can be positioned and moved. The transparent viewing plate 41 is installed inside the movable partition 45. In this way, through the movable partition 45 and the transparent viewing plate 41, blocking and protection can be achieved. During viewing, viewing can be carried out correspondingly through the transparent viewing plate 41. The lead screw slider 44 is installed at the upper end of the movable partition 45. The lead screw slider 44 is installed and connected to the internal lead screw of the lead screw body 42.

Thus, when the output end of the lead screw motor 43 drives the coupling to rotate forward and backward, the internal lead screw of the lead screw body 42 can be driven to rotate forward and backward. When the internal lead screw of the lead screw body 42 rotates forward and backward, the lead screw slider 44 on the periphery can move left and right. Then, the lead screw slider 44 can drive the movable partition 45 to move left and right, enabling it to be opened and closed for use. The lead screw body 42 is installed and connected to the potting machine case 6, so that it can be correspondingly installed and placed.

The lifting telescopic cylinder 32 is installed at the lower end of the concave seat housing 33, and the lower end of the telescopic rod of the lifting telescopic cylinder 32 is installed with a coating mechanism 5. Thus, when the telescopic rod of the lifting telescopic cylinder 32 expands and contracts, it can drive the coating mechanism 5 to perform lifting and sealing. The concave seat housing 33 is fixedly connected to the inner top end of the sealing glue box 6, so that it can be stably installed and placed.

[0034] Refer to Figure 1 , Figure 2 and Figure 4 , in a preferred embodiment, the coating mechanism 5 includes a sealing glue nozzle 51 and a sealing glue corrugated delivery pipe 52. The sealing glue corrugated delivery pipe 52 is installed at the outer end of the sealing glue nozzle 51. The sealing glue corrugated delivery pipe 52 is connected to the suction pump 31. The suction pump 31 can then deliver the extracted sealing glue into the sealing glue corrugated delivery pipe 52, and then into the sealing glue nozzle 51 for sealing the lower part. The sealing glue nozzle 51 is installed and connected to the lifting telescopic cylinder 32. Thus, the lifting telescopic cylinder 32 can drive the sealing glue nozzle 51 to lift, so that the sealing height position can be changed;

[0035] The sealing glue corrugated delivery pipe 52 and the suction pump 31 are installed and connected by screws, so that they can be correspondingly installed and fixed, and a rubber pad is placed at the connection, making the fixation more tight and firm.

[0036] Refer to Figure 1 , Figure 2 and Figure 5 , in a preferred embodiment, the sealing glue storage mechanism 2 includes a bottom discharge pipe 21, a glue storage sleeve cavity 22, a box cover 23, and a box body shell 24. The box cover 23 is installed at the upper end of the box body shell 24. When the operator opens the box cover 23, sealing glue can be added into the box body shell 24. The glue storage sleeve cavity 22 is provided inside the box body shell 24, so that the sealing glue can be stored. The bottom discharge pipe 21 is installed at the lowest position at the lower end of the box body shell 24. The bottom discharge pipe 21 is connected to the coating delivery mechanism 3, so that the coating delivery mechanism 3 can extract and deliver. The box body shell 24 is installed and connected to the sealing glue box 6, so that it can be stably placed and used.

[0037] Refer to Figures 1 - 3 , in a preferred embodiment, two protective shielding frames 4 are installed, and the protective shielding frames 4 are symmetrically installed on the sealing glue box 6, so that the protective shielding frames 4 can perform shielding protection on both sides of the sealing glue box 6.

[0038] Refer to Figure 1 and Figure 2, in a preferred embodiment, a center marking line 11 is drawn in the middle of the output belt of the sealant belt conveyor 1, so that the placement position can be determined for conveying the sealant.

[0039] Working principle: When in use, the operator places the LCM workpiece 8 on the sealant belt conveyor 1 at the upper end of the sealant machine case 6. Thus, the sealant belt conveyor 1 conveys the LCM workpiece 8 at the input end to below the gluing mechanism 5. The coating conveying mechanism 3 can extract the glue from the sealant glue storage mechanism 2 and convey it to the gluing mechanism 5. In this way, the gluing mechanism 5 can seal the LCM workpiece 8 below. During the sealing, the two protective shielding frames 4 can effectively shield the outside of the gluing mechanism 5, thus effectively isolating the entry of external substances and playing a good protective role. During maintenance, the protective shielding frame 4 can also be opened to facilitate the repair of the gluing mechanism 5.
