Description of the Invention: [Technical Field] The present invention relates to a gluing device and a gluing device use and maintenance method, and more particularly to a gluing device having a needle protection mechanism and the use of the gluing device and Maintenance method. a ' 【Previous technology】 At present, the 'coating machine has been widely used in various electronic devices such as batteries, PCB boards, Ic or liquid crystal displays (LCD), such as sealing, dispensing or gluing, and the coating of knee-coating machines The quality of the glue has a great influence on the packaging quality of the electronic φ device, especially as the sealing technology is gradually improved in the electronic manufacturing industry, and the performance requirements for the coating machine are also very high. 'Please refer to the conventional applicator 9 shown in the first figure, which has a valve 90 for controlling the flow rate of the glue, and a glue needle 91 for outputting the glue, such as coating the blue glue (Tu£fy glue) 92 The exposed circuit of the liquid crystal display module 8 can protect the exposed circuit from dust, moisture and the like. Since the surface drying time of the blue glue 92 in the natural state is about 3 to 5 minutes, when the glue application of the glue needle 91 is completed or suspended, the glue needle 91 needs to be immersed in the anti-dry liquid to avoid the glue application. The dry knot phenomenon of the needle 91 affects the subsequent glue application and even affects the service life of the glue needle 91. However, regardless of whether the rubberized needle 91 is immersed in the anti-drying liquid intermittently or continuously for a long period of time, the final elimination of the rubber needle 91 causes the rubberized needle 91 to expand and soften. When the expanded and softened rubberized needle 91 is in operation, 'because the rubberizing needle 91 expands slightly, the rubbering parameter must be adjusted first, that is, the bottom end 910 of the coating needle 91 and the liquid crystal display are adjusted. The glue distance between the predetermined glue zones of the module 8 'otherwise the glued needle 91 after expansion is likely to directly contact and scratch the predetermined glue zone. However, after the coating distance is adjusted, the rubberized needle 91 which has been expanded and softened may still exhibit poor rubber coating during the coating process. For example, the coating machine 9 applies the blue glue 92 to the liquid crystal display module 8 by moving the glue needle 91, but since the blue glue will have a certain flow resistance to the bottom end 91 of the glue needle 91, Adhesive force, so the rubberized needle 91 after softening is extremely prone to bending deformation, resulting in poor coating. At this point, the glue application must be suspended, and the glue parameters should be adjusted again, or the glue needle 91 can be directly replaced to continue the glue application or re-applied. 201004716 (4) Referring to the second applicator 9 shown in the second A circle and the second B, it can be found that the pin 1 is fixed to the knee 9 by the rotation setting mechanism 93. In detail, 'the careful turn σ, #_卿狮93 = the top 912 is fixed on the 〇9〇, but the bottom end 91 of the glue needle 91 is not fixed' can not solve the flexible needle 91 problem. Therefore, it is necessary to provide a new type of glue applicator to solve the problems in the test.

The tapered cylinder 51 (e.g., a member) has a top end 51 and a bottom end 512, and the cross-sectional area of the miscible 51 gradually decreases from the top end 51 to the bottom end S12. The top end 510 of the conical cylinder η is attached to the needle holder 20. The output end 32 of the coating needle 30 extends outwardly from the bottom end of the miscellaneous cylinder 51 for a distance to facilitate the application of the glue. For example, when the coating device i is applied to the panel manufacturing process or the module process of the liquid crystal display panel, the output end of the coating 3Q only needs to extend the cone 51 by about 1 mm. By means of the needle protection mechanism %, the glue pin 3 can be used to enhance the strength of the paint 3 ,, to avoid the deformation of the paint 3 〇 during the transfer process, thereby reducing the occurrence of poor glue and improving the glue application. In addition, the distance between the fixing mechanism 40 and the needle protecting mechanism 50 can be adjusted according to actual needs by the fixing mechanism 40 moving above and below the Z drawing direction on the guide rail 11, so that the needle protecting mechanism 50 The rubber needle 3 can be moved away from or held by the needle. For example, when the needle is removed, the slider 41 of the box fixing mechanism 40 moves upward along the guide U of the base 10 to drive the needle holder and the coating. The plastic needle 30 is raised and the conical cylinder 51 of the needle protection mechanism 5 is kept fixed to the movable position of the machine base, so that the distance between the two becomes larger, and the glue needle 3〇 is separated from the miscellaneous cylinder 51. In addition, it is convenient for the operator to easily change the glue needle 30. After the glue needle 30 is replaced, the slider 41 of the fixing mechanism 40 is driven to move downward again, so that the needle holder 2〇 and the glue needle 3〇 are lowered together until the needle holder 2 is lowered. The glue needle 30 is completely inserted into the miscible cylinder 51 for the glue Therefore, the present invention can quickly change the glue application needle 30, thereby improving work efficiency. In other embodiments of the present invention, the coating device (not shown) can also adjust the fixing mechanism and the needle protection by moving the needle protection mechanism. The distance between the mechanisms to replace the glue needle. For example, the needle protection mechanism (not shown) of other embodiments may include: a sliding member and a cone, the sliding member being slidably mounted on the rail of the base; The cone is connected to the sliding member and sleeved outside the glue needle. When the glue needle needs to be replaced, the sliding member of the driving needle protection mechanism slides down along the guide rail of the base to drive the cone downward. Slide until the cone is completely out of the glue needle, and the glue needle is exposed to the outside. At this time, the operator replaces the needle and the needle. After the glue needle is replaced, the slider of the needle protection mechanism is driven to slide upward again. In order to drive the cone to slide upward until the 201004716 needle is fully inserted into the cone for the glue application. The needle protection mechanism % and the fixing mechanism 4〇 according to the embodiment are combined. The following is a detailed description of the use and maintenance methods of the rubber device, which is the best way to use the squeezing device, including the steps υ to 7). The clothing step 1) provides the needle holder 2 涂 and the glue needle 3 〇, the knee-claw 3 可 is detachably assembled on the headstock 20 'The input end 31 of the glued needle 3 连接 is connected to the needle holder 2 以 for the glue to enter the glue needle 3 针 from the needle holder 20 2, the second step is to mount the needle holder 2 on the base 1 by using the fixing mechanism 4; in the present embodiment, the fixing mechanism 40 holds the needle holder 2 by the clamp a, and by means of the clamp The 42-connected 'moon block 41 is fixed on the guide rail 11 of the base 10. Step = 3) The female needle protection mechanism 5 is placed on the base 1 and is shaped by the 'adjustable distance between the fixed mechanism'. The needle protection mechanism 5 〇 can detachably hold the coating needle. In the present embodiment, since the needle-mechanism 50 is sleeved on the outside of the glue-coated needle 30 by the cone cylinder 51, the material of the wax-proof needle 3G' is deformed; at the same time, the cylinder 51 is coated with the needle 30. In the Deng operation, it is always fixed in the same position of the cone 51, even if the operator is slightly skewed when assembling the glue needle on the needle holder 2, the cone can be forcibly corrected to Therefore, the 'cylinder 51 can effectively correct the assembly position of the coating 3, thereby improving the assembly efficiency of 1. The rounded end 32 of the coated needle 3 is extended from the bottom end of the miscible cylinder 51 to facilitate the application of the glue. Step 4) Perform a knee-swinging action. The output of the sputum needle 3 & is output to the knee fluid. Since the glued needle 30 is not easily deformed by the protection of the cone 30, the number of adjustments is increased, thereby improving the glue application efficiency and improving the service life of the glue needle 3 . Step 4) will be applied. If the coating operation is completed successfully, step 5) is performed, and step 5) is immersed in a maintenance liquid (not shown) at the output end 32 of 30. In this step 5), most of the structure of the right glue needle 30 is covered by the miscellaneous tube of the needle protection mechanism 5, and only the output end 32 of the left coffee is in contact with the maintenance liquid, so the cone 51 is To a large extent, the isolation is provided as 201004716, so that the coating needle 30 does not directly contact the maintenance liquid, so that the rubber needle 3 swells and softens, thereby prolonging the service life of the glue needle 30. In this embodiment, the maintenance liquid is anti-dry liquid to prevent the glue needle 3 from drying out. According to the above step 4), if the glue needle 30 is carried in the glue coating process, the steps 6) and 7) 'step 6) are performed to increase the distance between the fixing mechanism 4〇 and the needle protection mechanism 5〇. The damaged glue needle 30 is removed from the needle protection mechanism 50. - Step 7) Replace the damaged glue needle 3〇, continue the glue application, and after the glue is applied, perform step 5). In detail, in the embodiment, when the glue needle 3 needs to be replaced, the slider 41 of the first fixing mechanism 40 is moved upward along the guide rail u of the base 10 to drive the needle holder 20 and the glue needle. 30 will rise together until the glue needle 3〇 will be separated from the cone 5ι; then the operator replaces the glue needle 3〇; then, the slider 41 of the medium fixing mechanism 4 moves downward to drive The needle holder 2〇 is lowered together with the glue application needle 30 until the glue needle 3〇 is completely inserted into the cone/tube 51, and then the glue application operation is continued. As described in the foregoing, in other embodiments, the glue needle 3 can be separated from the cone 51 by moving the needle protection mechanism 5, and the purpose of quickly changing the glue needle 3 can also be achieved.
