Description

Technical Field

[0001] This application relates to the technical field of processing and manufacturing, and in particular to a processing support device. Background Technology

[0002] In existing technologies, traditional operations require personnel to place the glass panel and bottom cover into separate carriers. Users must first attach the ribbon cable, then apply adhesive. After adhesive application, the assembly is transferred to a UV curing chamber for curing, then to assembly equipment for assembly, followed by pressure holding in a pressure-holding device, and finally to AOI (Automated Optical Inspection) equipment for height difference and gap detection. This cumbersome process reduces quality and efficiency. By implementing a universal assembly carrier, all actions can be completed within the carrier, reducing unnecessary transfers and minimizing operator contact with the product.

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 and Figure 2 , Figure 1 This is a perspective view of the processing support device of this application and Figure 2 This is an exploded perspective view. As shown in the figure, this embodiment provides a processing support device 1, including: a base 11, a cover plate carrier 13, and a panel carrier 15. The cover plate carrier 13 is disposed on the base 11 and has a fixed area 130. The panel carrier 15 includes two moving components 151, which are respectively located on both sides of the fixed area 130. The two moving components 151 are slidably disposed on the base 11 and slide relative to the fixed area 130 to form a support area 150, wherein the fixed area 130 located outside the vertical projection range of the support area 150 is the processing range 1301.

[0032] Please refer to the following: Figure 3 This is a schematic diagram of the processing support device of this application in use. In this embodiment, the user slides the two movable components 151 away from the fixed area 130, that is, slides the two movable components 151 outward, so that the cover plate 21 can be fixedly assembled from above the panel carrier 15 toward the fixed area 130 of the cover plate carrier 13. Furthermore, the two movable components 151 are slid toward the fixed area 130, and the structure of the two movable components 151 forms the support area 150 for placing the panel, that is, the two movable components 151 can be used to support the four corners of the panel 23, and the panel 23 is fixedly assembled in the support area 150, so that the panel 23 is located above the cover plate 21. Among them, the cover plate 21 located outside the vertical projection range of the panel 23 provides a processing range 1301 for the user to perform processing, in other words, the processing range 1301 provides the user with processing between the panel 23 and the cover plate 21. Furthermore, the processing support device 1 of this embodiment can be assembled on a processing machine, and the processing machine will perform processing through the processing range 1301 to process the cover plate 21 and the panel 23, so that the panel 23 is assembled on the cover plate 21.

[0033] Please refer to the following: Figures 4 to 6 , Figure 4 This is an exploded perspective view of the cover plate carrier of the processing bearing device of this application. Figure 5 This is a schematic diagram of the operation of the cover plate carrier. Figure 1 as well as Figure 6 This is a schematic diagram of the operation of the cover plate carrier. Figure 2 As shown in the figure, in this embodiment, the cover plate carrier 13 includes a body 131, a first pushing component 132, and a second pushing component 133. The body 131 has a first pushing groove 1311 and a second pushing groove 1312, which are interconnected. The first pushing groove 1311 extends on the body 131 in a first direction A, and the second pushing groove 1312 extends on the body 131 in a second direction B. The first direction A and the second direction B are perpendicular to each other. Furthermore, the first pushing component 132 is slidably disposed in the first pushing groove 1311, and the second pushing component 133 is slidably disposed in the second pushing groove 1312. The first pushing component 132 is linked to the second pushing component 133, and one end of the first pushing component 132 and one end of the second pushing component 133 move inward or outward from the fixed area 130 of the body 131.

[0034] Additionally, the main body 131 has an upper outer shell 1314 and a lower outer shell 1315. The upper outer shell 1314 is assembled onto the lower outer shell 1315. A first pushing groove 1311 and a second pushing groove 1312 are disposed on the lower outer shell 1315. The outer surface of the upper outer shell 1314 has a bearing area 150. The upper outer shell 1314 has a plurality of through holes 13140 located around the periphery of the fixed area 130. One end of the first pushing component 132 and one end of the second pushing component 133 move inward or outward within the fixed area 130 through the plurality of through holes 13140 in the upper outer shell 1314.

[0035] In this embodiment, the first pushing assembly 132 includes a first pushing member 1321 and a first elastic member 1322. The first pushing member 1321 is slidably disposed in the first pushing groove 1311, and the first elastic member 1322 is disposed between the groove wall of the first pushing groove 1311 and one end side of the first pushing member 1321. The elastic force direction of the first elastic member 1322 is the same as the pushing direction of the first pushing member 1321 within the first pushing groove 1311. The second pushing assembly 133 includes a second pushing member 1331 and a second elastic member 1332. The second pushing member 1331 is slidably disposed in the second pushing groove 1312, and the second elastic member 1332 is disposed between the groove wall of the second pushing groove 1312 and one end side of the second pushing member 1331. The elastic force direction of the second elastic member 1332 is the same as the pushing direction of the second pushing member 1331 within the second pushing groove 1312.

[0036] Furthermore, the first pushing member 1321 has a pushing rod 13211 and a pushing block 13212. The pushing rod 13211 and the pushing block 13212 are slidably disposed in the first pushing groove 1311. The user drives the pushing rod 13211 to move the pushing block 13212, causing one end of the pushing block 13212 to move inward or outward within the fixed area 130 of the body 131. The pushing rod 13211 has a concave wall 13213 on one side, and the concave surface of the concave wall 13213 is oriented in the same direction as the pushing direction of the second pushing member 1331. The other end of the second pusher 1331 abuts against the concave wall 13213 of the push rod 13211. The other end of the second pusher 1331 moves against the concave surface of the concave wall 13213. Thus, the second pusher 1331 moves with the concave wall 13213 within the second push groove 1312. In other words, the first pusher 1321 moves in conjunction with the second pusher 1331.

[0037] As described above, the top surface of one end of the pushing block 13212 of the first pushing member 1321 has a first moving post 1323, which protrudes from the surface of the body 131. The first moving post 1323 moves inward or outward within the fixed area 130. On the other side of the first moving post 1323 relative to the fixed area 130, there is a first fixed post 1324. Thus, the first moving post 1323 pushes the first side 211 of the cover plate 21, fixing the opposite side of the first side 211 of the cover plate 21 to the first fixed post 1324. Furthermore, one end of the top surface of the second pusher 1331 has a second moving post 1333, which protrudes from the surface of the body 131. The second moving post 1333 moves inward or outward in the fixed area 130. The other side of the second moving post 1333 relative to the fixed area 130 has a second fixed post 1334. Thus, the second moving post 1333 pushes the second side 212 of the cover plate 21, so that the opposite side of the second side 212 of the cover plate 21 is fixed to the second fixed post 1334.

[0038] In addition, the first push groove 1311 extends out of the body 131 in the first direction A, and the side of the body 131 forms a push port 1310. The push rod 13211 of the first push member 1321 is located in the push port 1310. The side of the push rod 13211 of the first push member 1321 has a limiting protrusion 1325. The body 131 has a limiting groove 1313 corresponding to the limiting protrusion 1325. The limiting groove 1313 is connected to the first push groove 1311. The limiting groove 1313 restricts the movement of the limiting protrusion 1325 of the push rod 13211 of the first push member 1321.

[0039] Please refer to the following: Figure 5 and Figure 6When the user wants to fix the cover plate 21 using the cover plate carrier 13, the user first drives the push rod 13211 through the push port 1310. The push rod 13211 pushes the push block 13212, and the push block 13212 moves the first moving column 1323 outwards from the fixed area 130. The concave wall 13213 of the push rod 13211 moves the second push member 1331, and the second push member 1331 moves the second moving column 1333 outwards from the fixed area 130. After the cover plate 21 is placed in the fixed area 130, the user no longer applies force to the push rod 13211. The push block 13212 of the first push member 1321 is pushed back by the elastic force of the first elastic member 1322, causing the first push member 1321 to slide back to the original position of the first push groove 1311, and causing the first moving column 1323 of the first push member 1321 to push the cover plate 21 against the first fixed column 1324. In addition, the second pushing member 1331 is also pushed back by the elastic force of the second elastic member 1332, causing the second pushing member 1331 to slide back to the original position of the second pushing groove 1312, so that the second moving column 1333 of the second pushing member 1331 pushes the cover plate 21 against the second fixed column 1334. In this way, the cover plate 21 is fixed between the first moving column 1323, the second moving column 1333, the first fixed column 1324, and the second fixed column 1334.

[0040] Please refer to the following: Figures 7 to 9 , Figure 7 This is another exploded perspective view of the processing support device of this application. Figure 8 This is a diagram illustrating the operation of the panel vehicle. Figure 1 and Figure 9 This is a diagram illustrating the operation of the panel vehicle. Figure 2 As shown in the figure, in this embodiment, the base 11 has two slide rail assemblies 111, which are located on both sides of the cover plate carrier 13, and each slide rail assembly 111 has two slide rails 1111. Each moving assembly 151 has a moving body 1511 and two sliders 1512, which are disposed on the bottom sides of the moving body 1511 and are slidably disposed on the two slide rails 1111 of the slide rail assembly 111.

[0041] Furthermore, the panel carrier 15 includes two limiting components 152, which respectively restrict the movement of the two moving components 151 toward the fixed area 130 and away from the fixed area 130. More specifically, each limiting component 152 includes an inner limiting member 1521 and an outer limiting member 1522. The inner limiting member 1521 is located on the side closer to the fixed area 130, and the outer limiting member 1522 is located on the side away from the fixed area 130. The moving component 151 further includes a moving limiting member 1513, which is disposed on the moving body 1511. The inner limiting member 1521 and the outer limiting member 1522 are located on the movement path of the moving limiting member 1513.

[0042] As described above, the movable limiting member 1513 has a protrusion 15131 on one side relative to the inner limiting member 1521, and the inner limiting member 1521 has a fixing portion 15211 relative to the movable limiting member 1513. The protrusion 15131 of the movable limiting member 1513 is movably fixed to the fixing portion 15211 of the inner limiting member 1521. Furthermore, the fixing portion 15211 has a fixing groove 15212 and two fixing protrusions 15213. The two fixing protrusions 15213 are disposed on both sides of the fixing groove 15212. The protrusion 15131 of the movable limiting member 1513 is fitted into the fixing groove 15212, and the fixing protrusions 15213 are clamped to the protrusion 15131. Thus, the movable limiting member 1513 is connected and fixed to the fixing portion 15211 of the inner limiting member 1521.

[0043] Furthermore, the panel carrier 15 includes two support components 153, each with two support members 1531. The two support members 1531 are respectively disposed on the top sides of the movable body 1511, symmetrically arranged on the movable body 1511. Each support member 1531 has a support groove 15311, which is used to support the corners of the panel 23. Thus, the two support components 153 support the four corners of the panel 23. Further, the bottom of the support groove 15311 has a recess 15312, which can prevent electrostatic adsorption between the corners of the panel 23 and the groove surface of the support groove 15311.

[0044] The panel carrier 15 further includes two grips 154, which are mounted on two movable components 151. The user can operate the two grips 154 to push or pull back the two movable components 151, causing the sliders 1512 of the movable components 151 to move relative to the slide rails 111. Furthermore, the panel carrier 15 also includes two pushers 155, which are located on the outer sides of the two movable components 151. The user can also operate the two pushers 155 to push or pull back the two movable components 151, which will not be described further here.

[0045] In summary, this application provides a processing support device that uses a fixing area of ​​a cover plate carrier to fix a cover plate and a bearing area of ​​a panel carrier to fix a panel, and performs processing and assembly through the processing range of the cover plate and the panel. This processing support device can improve the assembly efficiency and manufacturing quality of the cover plate and the panel.
