Description

Technical Field

[0001] This application relates to the field of fiber optic panel splicing technology, and in particular to a splicing device and splicing method. Background Technology

[0002] Fiber optic panels (also known as fiber panels) possess characteristics such as high light transmission efficiency, low interstage coupling loss, realistic and clear image transmission, and optically zero thickness, making them crucial for improving image quality. Fiber optic panels are widely used in various cathode ray tubes, camera tubes, CCD couplings, and other small instruments and equipment requiring image transmission.

[0003] Currently, the size of fiber optic panels is limited by the size of the vacuum furnace used to manufacture them. To further increase the size of fiber optic panels, there are two main methods: first, to enlarge the size of the vacuum furnace; second, to glue multiple small fiber optic panels together using adhesive.

[0004] However, increasing the size of the vacuum furnace will lead to increased costs, while the method of splicing by adhesive will result in low overall strength of the fiber optic panel and reduced transmittance of the bonded parts, which will seriously affect the quality of the panel. Summary of the Invention

[0037] First aspect

[0038] This application provides a splicing device 100, see [link to relevant documentation] Figures 1 to 8 As shown, the splicing device 100 includes a housing 10 and a welding assembly 20. The housing 10 includes a first structural member 11, a second structural member 12, a third structural member 13, and a fourth structural member 14. The first structural member 11, the second structural member 12, the third structural member 13, and the fourth structural member 14 are arranged to enclose and define a splicing space extending in the vertical direction. The first structural member 11 and the third structural member 13 are opposite each other and have a first channel 111 and a second channel 131 that are opposite each other. The second structural member 12 is opposite to the fourth structural member 14. The welding assembly 20 includes a first welding assembly 21 and a second welding assembly 22. The first welding assembly 21 and the second welding assembly 22 are respectively arranged on opposite sides of the second structural member 12 and the fourth structural member 14. The first weld joint 211 of the first welding assembly 21 and the second weld joint 221 of the second welding assembly 22 are opposite each other and have a gap distance. The first weld joint 211 and the second weld joint 221 can move synchronously in the vertical direction.

[0039] Specifically, the splicing device 100 described above is used to connect one end of the first splicing board 201 and one end of the second splicing board 202 to splice them together to form a larger board. For example, if both the first splicing board 201 and the second splicing board 202 are fiber optic panels, then connecting them using the splicing device 100 can form a larger fiber optic panel, thereby meeting the market demand for large-size fiber optic panels.

[0040] The aforementioned box 10 includes: a first structural member 11, a second structural member 12, a third structural member 13, and a fourth structural member 14. The first structural member 11, the second structural member 12, the third structural member 13, and the fourth structural member 14 are arranged to enclose and define a splicing space extending in the vertical direction. The first structural member 11 and the third structural member 13 are opposite each other, and the second structural member 12 and the fourth structural member 14 are opposite each other. Thus, the first structural member 11, the second structural member 12, the third structural member 13, and the fourth structural member 14 can be a frame structure with ends connected to form a rectangle, a circle, or other shapes. Alternatively, the first structural member 11, the second structural member 12, the third structural member 13, and the fourth structural member 14 can be aligned end to end, and adjacent structural members can be connected by other structural members to form a frame structure that is close to a rectangle, a circle, or other shapes.

[0041] For example: the first structural component 11, the second structural component 12, the third structural component 13, and the fourth structural component 14 are all flat plates, and the first structural component 11, the second structural component 12, the third structural component 13, and the fourth structural component 14 are connected end to end to form a rectangular frame structure; for another example: the first structural component 11, the second structural component 12, the third structural component 13, and the fourth structural component 14 are all curved plates, and the first structural component 11, the second structural component 12, the third structural component 13, and the fourth structural component 14 are connected end to end to form a circular frame structure; for yet another example: the first structural component 11, the second structural component 12, the third structural component 13, and the fourth structural component 14 are all flat plates, the first structural component 11, the second structural component 12, the third structural component 13, and the fourth structural component 14 are aligned end to end, and adjacent structural components are connected by flat plates inclined to the adjacent two structural components to form a cross surface between the adjacent two structural components. Here, the first structural component 11, the second structural component 12, the third structural component 13, and the fourth structural component 14 forming the box 10 can be selected as planar or curved surfaces, and can be directly or indirectly connected according to actual needs, so as to provide a flexible setting method. For example, in order to reduce the space occupation, the four structural components can be directly connected end to end to form a circular frame.

[0042] The first structural member 11 and the third structural member 13 described above are respectively provided with a first channel 111 and a second channel 131 facing each other. The first channel 111 and the second channel 131 can extend horizontally, thus facilitating the facing of the first splicing plate 201 passing through the first channel 111 and the second splicing plate 202 passing through the second channel 131. This reduces the need for relative facing operations on the first and second splicing plates 201 and 202 passing through the first channel 111, thereby improving splicing efficiency. The radial dimension of the first channel 111 is large enough to accommodate first splicing plates 201 of different sizes, and the radial dimension of the second channel 131 is large enough to accommodate second splicing plates 202 of different sizes. This enhances the versatility of the splicing equipment 100 and reduces the cost of splicing first and second splicing plates 201 and 202 of different sizes.

[0043] The aforementioned welding assembly 20 includes a first welding assembly 21 and a second welding assembly 22. The first welding assembly 21 and the second welding assembly 22 are respectively disposed on opposite sides of the second structural member 12 and the fourth structural member 14. The first weld joint 211 of the first welding assembly 21 and the second weld joint 221 of the second welding assembly 22 are opposite to each other and have a gap. The first weld joint 211 and the second weld joint 221 can move synchronously in the vertical direction, thus allowing for welding of the first plate to be spliced ​​201 and the second plate to be spliced ​​202. After being respectively installed in the first channel 111 and the second channel 131, the seam where the first splicing plate 201 and the second splicing plate 202 come into contact with each other is located between the first fusion joint 211 and the second fusion joint 221. The first fusion joint 211 and the second fusion joint 221 can move along one end of the seam to the other end of the seam. During the movement, the first fusion joint 211 and the second fusion joint 221 provide high temperature so that the position where the first splicing plate 201 and the second splicing plate 202 come into contact with each other melts so that they can be connected together.

[0044] In one embodiment, see Figures 1 to 8As shown, the splicing device 100 includes a housing 10 and a welding assembly 20. The housing 10 includes a first structural member 11, a second structural member 12, a third structural member 13, and a fourth structural member 14 connected end-to-end to form a rectangular frame extending vertically. The first structural member 11 and the third structural member 13 are opposite each other and each has a first channel 111 and a second channel 131 that are opposite each other and extend horizontally. The second structural member 12 is opposite to the fourth structural member 14. The welding assembly 20 includes a first welding assembly 21 and a second welding assembly 22. The first welding assembly 21 and the second welding assembly 22 are respectively disposed on opposite sides of the second structural member 12 and the fourth structural member 14. The first weld joint 211 of the first welding assembly 21 and the second weld joint 221 of the second welding assembly 22 are opposite each other and have a gap, and the first weld joint 211 and the second weld joint 221 can move synchronously in the vertical direction.

[0045] One splicing method corresponding to this embodiment is as follows:

[0046] S101: The first panel to be spliced ​​201 is horizontally inserted through the first channel 111;

[0047] S102: The second panel to be spliced ​​202 is horizontally inserted into the second channel 131;

[0048] S103: Connect the first splicing plate 201 and the second splicing plate 202 in the splicing space, and align the joint between the two between the first fusion joint 211 and the second fusion joint 221.

[0049] S104: Control the first fusion joint 211 and the second fusion joint 221 to move synchronously from one end of the joint to the other end of the joint with a working power less than the preset power. The first fusion joint 211 and the second fusion joint 221 generate an electric arc to release high temperature, thereby preheating the joint.

[0050] S105: Control the first fusion joint 211 and the second fusion joint 221 to move synchronously from one end of the joint to the other end of the joint with a working power greater than the preset power. The first fusion joint 211 and the second fusion joint 221 generate an electric arc to release higher temperatures, so that the position where the first plate to be spliced ​​201 and the second plate to be spliced ​​202, which are located at the center of the electric arc between the first fusion joint 211 and the second fusion joint 221, can be heated to about 1500°C to melt and then connect them together.

[0051] Here, the preset power is less than the rated power of the first fusion joint 211 / the second fusion joint 221, for example: the preset power is 1 / 2 of the power of the first fusion joint 211 / the second fusion joint 221.

[0052] In this embodiment, the housing 10 of the splicing device 100 forms a splicing space extending in a vertical direction. One end of the first splicing plate 201 and one end of the second splicing plate 202 can extend into the splicing space inside the housing 10 from the first channel 111 and the second channel 131 that are opposite to each other on the housing 10, respectively. Then, the first welding joint 211 of the first welding assembly 21 and the second welding joint 221 of the second welding assembly 22 can move synchronously from the end of the first splicing plate 201 and the second splicing plate 202 that are in contact with each other in the splicing space to the other end, so that the parts of the first splicing plate 201 and the second splicing plate 202 that are in contact with each other can be melted and connected together. When the first splicing board 201 and the second splicing board 202 are fiber optic panels, the size of the vacuum furnace does not need to be adjusted in order to obtain a large-size fiber optic panel, which can reduce the increase in cost. Compared with adhesive bonding, fusion splicing results in higher overall strength and transmittance after splicing, which can improve the quality of the large-size fiber optic panel after fusion splicing. At the same time, fusion splicing has significant advantages such as reducing boundary image transmission, distortion, and image shift, thus laying a good foundation for the fabrication of ultra-large fiber optic panels.

[0053] In some embodiments, the first structural component 11, the second structural component 12, the third structural component 13, and the fourth structural component 14 are all opaque structural components. This can be achieved by spraying or pasting an opaque layer onto the surfaces of the first structural component 11, the second structural component 12, the third structural component 13, and the fourth structural component 14, or by using opaque materials to manufacture the first structural component 11, the second structural component 12, the third structural component 13, and the fourth structural component 14, or by other methods. When the first structural component 11, the second structural component 12, the third structural component 13, and the fourth structural component 14 are opaque structural components, the probability of glare generated during the welding process entering the eyes of workers can be reduced, thereby improving operational safety.

[0054] In some embodiments, see Figure 3 , Figure 6 and Figure 8 As shown, the second structural component 12 is provided with a first slide rail 122 extending in the vertical direction, and the first welding assembly 21 includes: a first slider 212, which is connected to the first slide rail 122 and can slide back and forth in the vertical direction along the first slide rail 122, and the first slider 212 is connected to a first welding head 211; the fourth structural component 14 is provided with a second slide rail 141 extending in the vertical direction, and the second welding assembly 22 includes: a second slider 222, which is connected to the second slide rail 141 and can slide back and forth in the vertical direction along the second slide rail 141, and the second slider 222 is connected to a second welding head 221; wherein, both the first slider 212 and the second slider 222 are connected to the first servo motor.

[0055] Specifically, the second structural component 12 mentioned above is provided with a first slide rail 122 extending in the vertical direction. The first welding assembly 21 includes a first slider 212, which is connected to the first slide rail 122 and can slide back and forth in the vertical direction along the first slide rail 122. The first slider 212 is connected to a first welding joint 211. In other words, the first welding joint 211 is slidably connected to the first slide rail 122 extending in the vertical direction on the second structural component 12 through the first slider 212. In this way, under the cooperation of the first slide rail 122 and the first slider 212, the probability of the first welding joint 211 deviating from the splicing position of the first splicing plate 201 and the second splicing plate 202 can be reduced. At the same time, welding along the preset trajectory can improve the welding qualification rate.

[0056] The fourth structural component 14 described above is provided with a second slide rail 141 extending in the vertical direction. The second welding assembly 22 includes a second slider 222, which is connected to the second slide rail 141 and can slide back and forth in the vertical direction along the second slide rail 141. The second slider 222 is connected to a second welding head 221. Thus, with the cooperation of the second slide rail 141 and the second slider 222, the probability of the second welding head 221 deviating from the splicing position of the first splicing plate 201 and the second splicing plate 202 can be reduced. At the same time, welding along a preset trajectory can improve the welding qualification rate.

[0057] The first slider 212 and the second slider 222 mentioned above are both connected to the first servo motor, so that the first servo motor can provide a driving force for synchronous movement to the first slider 212 and the second slider 222, thereby realizing the synchronous movement of the first weld joint 211 and the second weld joint 221; of course, other methods can also be used to realize the synchronous movement of the first weld joint 211 and the second weld joint 221.

[0058] In one embodiment, the first slide rail 122 on the second structural member 12 is a first slide groove extending vertically. The slide groove space in the horizontal direction has a convex cross-section. The first slider 212 has an I-shaped cross-section in the horizontal direction. One end of the first slider 212 is located in the first slide groove so that the first slider 212 can slide up and down along the first slide groove, thereby realizing the up and down sliding of the first weld joint 211 connected to the first slider 212. The second slide rail 141 on the fourth structural member 14 is a second slide groove extending vertically. The second slide groove has a convex cross-section in the horizontal direction. The second slider 222 has an I-shaped cross-section in the horizontal direction. One end of the second slider 222 is located in the second slide groove so that the second slider 222 can slide up and down along the second slide groove, thereby realizing the up and down sliding of the second weld joint 221 connected to the second slider 222. Here, the first slider 212 located in the first slide groove can contact the inner surface of the first slide groove to reduce the situation where the first slider 212 gets stuck when sliding relative to the first slide groove; the second slider 222 located in the second slide groove can contact the inner surface of the second slide groove to reduce the situation where the second slider 222 gets stuck when sliding relative to the second slide groove.

[0059] In this embodiment, the first weld joint 211, through the cooperation of the first slider 212 and the first slide rail 122, can move more precisely in the vertical direction relative to the second structural member 12. The second weld joint 221, through the cooperation of the second slider 222 and the second slide rail 141, can move more precisely in the vertical direction relative to the fourth structural member 14. This reduces the bending of the splicing seam after the first splicing plate 201 and the second splicing plate 202 are spliced, thereby improving the aesthetics of the splicing position of the first splicing plate 201 and the second splicing plate 202.

[0060] In some embodiments, see Figure 1 , Figure 2 and Figures 6 to 8As shown, the housing 10 also includes a fifth structural member 15, which is located above the first structural member 11, the second structural member 12, the third structural member 13 and the fourth structural member 14, and is connected to the first structural member 11, the second structural member 12, the third structural member 13 and the fourth structural member 14 respectively. The fifth structural member 15 is provided with an opening 151 that connects to the splicing space or a viewing window corresponding to the splicing space. Alternatively, the fifth structural component 15 forms the top cover of the box 10. The opening 151 on the fifth structural component 15 that connects to the splicing space or the corresponding viewing window of the splicing space allows the staff to observe whether the first splicing plate 201 and the second splicing plate 202 in the splicing space are in contact, whether the contact position corresponds between the first weld joint 211 and the second weld joint 221, and whether there are foreign objects in the splicing space. The staff can also perform maintenance, replacement and other operations on the structure of the splicing space through the opening 151. The setting of the viewing window can reduce the probability of foreign objects entering the splicing space.

[0061] The fifth structural component 15 can be an opaque structural component. This can be achieved by applying an opaque layer to the surface of the fifth structural component 15 through spraying, pasting, or other methods, or by using an opaque material to manufacture the fifth structural component 15, or by other methods. When the fifth structural component 15 is an opaque structural component, the probability of glare generated during the welding process entering the eyes of workers can be reduced, thereby improving work safety.

[0062] The enclosure 10 may further include a sixth structural member, which is located below the first structural member 11, the second structural member 12, the third structural member 13, and the fourth structural member 14, and is connected to the first structural member 11, the second structural member 12, the third structural member 13, and the fourth structural member 14 respectively, and the sixth structural member is opposite to the fifth structural member 15. For example, the enclosure 10 is enclosed and connected by the first structural member 11, the second structural member 12, the third structural member 13, the fourth structural member 14, the fifth structural member 15, and the sixth structural member to form a closed structure with splicing space, so as to better protect the structure of the splicing space.

[0063] In some embodiments, see Figure 1 , Figure 2 and Figures 6 to 8As shown, the first structural component 11, the second structural component 12, the third structural component 13, the fourth structural component 14, and the fifth structural component 15 are all opaque components. The housing 10 also includes a hinge seat 16 and a cover plate 17. The hinge seat 16 is connected to the side of the fifth structural component 15 away from the splicing space. One end of the cover plate 17 is hinged to the hinge seat 16, so that the cover plate 17 can rotate relative to the fifth structural component 15 and cover the opening 151 or the viewing window. The cover plate 17 is opaque. In this way, the cover plate 17, which is rotatably connected to the outside of the fifth structural component 15, can cover the opening 151 or the viewing window, thereby further reducing the probability of glare generated during the welding process entering the eyes of the workers and improving work safety.

[0064] In some embodiments, the length of the first channel 111 is greater than the thickness of either the second structural member 12 or the fourth structural member 14; the length of the second channel 131 is greater than the thickness of either the second structural member 12 or the fourth structural member 14.

[0065] The length of the first channel 111 is greater than the thickness of either the second structural member 12 or the fourth structural member 14. This can be achieved by increasing the overall thickness of the first structural member 11, increasing the thickness of the portion of the first structural member 11 corresponding to the first channel 111, or by providing an extension of the first channel 111 on one side of the first structural member 11 corresponding to the splicing space and / or on the side away from the splicing space. The length of the second channel 131 is greater than the thickness of either the second structural member 12 or the fourth structural member 14. This can be achieved by increasing the overall thickness of the third structural member 13, increasing the thickness of the portion of the third structural member 13 corresponding to the second channel 131, or by providing an extension of the second channel 131 on one side of the third structural member 13 corresponding to the splicing space and / or on the side away from the splicing space.

[0066] When the length of the first channel 111 is large, the first plate to be spliced ​​201 passes through the first channel 111, and the support force of the first channel 111 on the first plate to be spliced ​​201 is greater, so as to reduce the situation where the first plate to be spliced ​​201 shakes during the welding process and thus affects the welding quality; when the length of the second channel 131 is large, the second plate to be spliced ​​202 passes through the second channel 131, and the support force of the second channel 131 on the second plate to be spliced ​​202 is greater, so as to reduce the situation where the second plate to be spliced ​​202 shakes during the welding process and thus affects the welding quality.

[0067] In some embodiments, see Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the two inner walls of the first channel 111, which are opposite to each other, are respectively provided with a third slide rail 1111 and a fourth slide rail 1112. The extension direction of the third slide rail 1111 and the extension direction of the fourth slide rail 1112 are both parallel to the extension direction of the first channel 111. The splicing device 100 also includes: a first connecting component 31 and a second connecting component 32. The first connecting component 31 is slidably connected to the third slide rail 1111, and the second connecting component 32 is slidably connected to the fourth slide rail 1112. The first connecting component 31 and the second connecting component 32 are opposite to each other.

[0068] The first connecting component 31 and the second connecting component 32 are opposite to each other, so that the first connecting component 31 and the second connecting component 32 can be located on opposite sides of the first panel to be spliced ​​201. In this way, the first connecting component 31 and the second connecting component 32 can respectively connect the opposite sides of the first panel to be spliced ​​201 to fix the first panel to be spliced ​​201, or the first connecting component 31 and the second connecting component 32 can cooperate to press the opposite sides of the first panel to be spliced ​​201 to fix the first panel to be spliced ​​201. The first connecting component 31 is slidably connected to the third slide rail 1111, and the second connecting component 32 is slidably connected to the fourth slide rail 1112. Thus, after the first connecting component 31 and the second connecting component 32 fix the first panel to be spliced ​​201, they can slide the first panel to be spliced ​​201 along the third slide rail 1111 and the fourth slide rail 1112 towards the inside or outside of the box 10, so that the sliding process of the first panel to be spliced ​​201 within the first channel 111 is more stable.

[0069] In one embodiment, the first connecting component 31 and the second connecting component 32 may be respectively provided with suction cups so that they can be attached to the opposite sides of the first splicing plate 201. Since the suction cups are made of flexible material, the probability of scratching the first splicing plate 201 can be reduced.

[0070] In some embodiments, see Figure 4 and Figure 5As shown, the first connecting assembly 31 includes a third slider 311 and a first clamping part 312, wherein the third slider 311 is slidably connected to the third slide rail 1111 and connected to the first clamping part 312; the second connecting assembly 32 includes a fourth slider 321 and a second clamping part 322, wherein the fourth slider 321 is slidably connected to the fourth slide rail 1112 and connected to the second clamping part 322; wherein the first clamping part 312 and the third slider 311 are movably connected, and / or the second clamping part 322 and the fourth slider 321 are movably connected, so that the distance between the first clamping part 312 and the second clamping part 322 changes. Alternatively, the movable connection between the first clamping part 312 and the third slider 311 allows the first clamping part 312 to move closer to or further away from the second clamping part 322, and the movable connection between the second clamping part 322 and the fourth slider 321 allows the second clamping part 322 to move closer to or further away from the first clamping part 312. Thus, after the first splicing plate 201 is located between the first clamping part 312 and the second clamping part 322, the first splicing plate 201 can be clamped on opposite sides by the movement of one or both of the first clamping part 312 and the second clamping part 322.

[0071] The third slider 311 and the fourth slider 321 corresponding to the first clamping part 312 and the second clamping part 322, which are opposite to each other, can both be connected to the second servo motor to achieve synchronous sliding of the third slider 311 and the fourth slider 321. The surfaces of the first clamping part 312 and the second clamping part 322 that release the first splicing plate 201 can both be elastic to reduce the probability of scratching the first splicing plate 201. For example, the first clamping part 312 and the second clamping part 322 can both be elastic pads.

[0072] In some embodiments, see Figure 4 and Figure 5 As shown, a first telescopic rod 313 is connected to the third slider 311, and the first telescopic rod 313 is connected to the first clamping part 312. The extension and retraction of the first telescopic rod 313 causes the first clamping part 312 to move closer to or further away from the second clamping part 322. A second telescopic rod 323 is connected to the fourth slider 321, and the second telescopic rod 323 is connected to the second clamping part 322. The extension and retraction of the second telescopic rod 323 causes the second clamping part 322 to move closer to or further away from the first clamping part 312. Thus, by extending and retracting the first telescopic rod 313, the first clamping part 312 connected to the first telescopic rod 313 can move closer to or further away from the second clamping part 322. By extending and retracting the second telescopic rod 323, the second clamping part 322 connected to the second telescopic rod 323 can move closer to or further away from the first clamping part 312, thereby adjusting the distance between the first clamping part 312 and the second clamping part 322.

[0073] The first telescopic rod 313 can be formed by two pipe fittings connected together, and the pipe fittings can be round pipes, flat pipes, or pipe fittings of other shapes; the first telescopic rod 313 can also be other configurations, which are not specifically limited here.

[0074] In some embodiments, see Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, there are multiple sets of first connecting components 31, distributed vertically; there are also multiple sets of second connecting components 32, distributed vertically and corresponding one-to-one with the sets of first connecting components 31. Thus, multiple first connecting components 31 are located on one side of the first plate to be spliced ​​201, and multiple second connecting components 32 are located on the other side of the first plate to be spliced ​​201, allowing for simultaneous fixation of the first plate to be spliced ​​201 during the welding process, thereby improving the fixation effect and ensuring the welding effect.

[0075] During the splicing operation, the first plate to be spliced ​​201 can be pre-fixed by a set of first connecting components 31 and a set of second connecting components 32 corresponding to each other. Then, after aligning the splicing seams of the first plate to be spliced ​​201 and the second plate to be spliced ​​202 located in the splicing space between the first weld joint 211 and the second weld joint 221, the remaining first connecting components 31 and the second connecting components 32 are used to fix the first plate to be spliced ​​201. In this way, the remaining first connecting components 31 and the second connecting components 32 can be located at the end of the first channel 111 away from the splicing space, so that the first plate to be spliced ​​201 is fixed by the first connecting components 31 and the second connecting components 32 at both ends of the first channel 111, thereby improving the fixing effect and ensuring the welding effect.

[0076] In some embodiments, see Figure 3 As shown, the two inner walls of the second channel 131 opposite to each other are respectively provided with a fifth slide rail 1311 and a sixth slide rail 1312. The extension direction of the fifth slide rail 1311 and the extension direction of the sixth slide rail 1312 are both parallel to the extension direction of the second channel 131. The fifth slide rail 1311 is slidably connected to a third connecting component (not shown in the figure), and the sixth slide rail 1312 is slidably connected to a fourth connecting component (not shown in the figure), and the third connecting component and the fourth connecting component are opposite to each other. The splicing device 100 may also include a display touch screen 41, which is disposed on the outside of the housing 10 and is electrically connected to the welding component 20, the first connecting component 31, the second connecting component 32, the third connecting component and the fourth connecting component respectively.

[0077] The fifth slide rail 1311 can be set with reference to the third slide rail 1111, the sixth slide rail 1312 can be set with reference to the fourth slide rail 1112, the third connecting component can be set with reference to the first connecting component 31, and the fourth connecting component can be set with reference to the second connecting component 32; or, the fifth slide rail 1311 can be set with reference to the fourth slide rail 1112, the sixth slide rail 1312 can be set with reference to the third slide rail 1111, the third connecting component can be set with reference to the second connecting component 32, and the fourth connecting component can be set with reference to the first connecting component 31. When the first panel to be spliced ​​201 slides smoothly towards or away from the splicing space under the fixing action of the first connecting component 31 and the second connecting component 32, the second panel to be spliced ​​202 slides smoothly towards or away from the splicing space under the fixing action of the third connecting component and the fourth connecting component, the second panel to be spliced ​​202 slides smoothly towards or away from the splicing space under the fixing action of the fifth slide rail 1311 and the sixth slide rail 1312.

[0078] The display touch screen 41 can display information and also be touched. The display and touch can be the same information on the same structure, or the information on different structures can be displayed and touched separately.

[0079] When the touch screen 41 is electrically connected to the welding assembly 20, the touch screen 41 can display the synchronous welding progress of the first weld joint 211 of the first welding assembly 21 and the second weld joint 221 of the second welding assembly 22. For example, the touch screen 41 can be connected to the first slider 212 and the second slider 222 to display the welding progress as 1 / 3 complete, 1 / 2 complete, or welding complete after obtaining the moving distance of the first slider 212 and the second slider 222. The touch screen 41 can also control the working state of the first weld joint 211 of the first welding assembly 21 and the second weld joint 221 of the second welding assembly 22. For example, the touch screen 41 can be connected to the first servo motor to control the working state of the first servo motor, thereby controlling the working state of the first weld joint 211 and the second weld joint 221 to start working, pause working, stop working, increase power, decrease power, etc.

[0080] When the touch screen 41 is electrically connected to the first connecting component 31, the second connecting component 32, the third connecting component, and the fourth connecting component, the touch screen 41 can display the sliding progress of the first connecting component 31, the second connecting component 32, the third connecting component, and the fourth connecting component relative to the corresponding slide rails. The sliding progress includes 1 / 3 completed, 1 / 2 completed, sliding complete, etc. The touch screen 41 can also control the working status of the first connecting component 31, the second connecting component 32, the third connecting component, and the fourth connecting component. For example, the touch screen 41 can be connected to the servo motor that drives the first connecting component 31, the second connecting component 32, the third connecting component, and the fourth connecting component to control the working status of the first connecting component 31, the second connecting component 32, the third connecting component, and the fourth connecting component. The working status includes: start working, pause working, stop working, etc.

[0081] The welding progress and sliding progress can be set by having a signal receiver on the slider and a signal transmitter on the corresponding slide rail. When the slider slides to different positions on the slide rail, the signal receiver receives different signals to confirm the position of the slider, and thus confirm the corresponding welding progress and sliding progress.

[0082] The housing 10 can be equipped with a high-voltage power supply that provides power to the display touch screen 41, the welding assembly 20, the first connecting assembly 31, the second connecting assembly 32, the third connecting assembly, and the fourth connecting assembly, so that the power supply settings can be integrated on the splicing equipment 100; the housing 10 can also be equipped with control buttons that control the working status of the welding assembly 20, the first connecting assembly 31, the second connecting assembly 32, the third connecting assembly, and the fourth connecting assembly, so that the welding assembly 20, the first connecting assembly 31, the second connecting assembly 32, the third connecting assembly, and the fourth connecting assembly can be controlled when the display touch screen 41 fails.

[0083] Second aspect

[0084] This application provides a splicing method, which is applied to the splicing device 100 described above. See also... Figure 9 As shown, the splicing methods include:

[0085] S101: The first panel to be spliced ​​201 is inserted through the first channel 111;

[0086] S102: Insert the second splicing plate 202 through the second channel 131;

[0087] S103: Connect the first splicing plate 201 and the second splicing plate 202 in the splicing space, and align the joint between the two between the first fusion joint 211 and the second fusion joint 221.

[0088] S104: Control the first fusion joint 211 and the second fusion joint 221 to move synchronously from one end of the joint to the other end of the joint at a working power less than the preset power.

[0089] S105: Control the first welding joint 211 and the second welding joint 221 to move synchronously from one end of the joint to the other end of the joint at a working power greater than the preset power.

[0090] The preset power can be 1 / 3 or 1 / 2 of the power of the first welding joint 211 / second welding joint 221, etc. When the first welding joint 211 and the second welding joint 221 are controlled to move synchronously from one end of the joint to the other end of the joint at a working power less than the preset power, the joint of the first plate to be spliced ​​201 and the second plate to be spliced ​​202 can be preheated. When the first welding joint 211 and the second welding joint 221 are controlled to move synchronously from the other end of the joint to one end of the joint at a working power greater than the preset power, the joint of the first plate to be spliced ​​201 and the second plate to be spliced ​​202 can be heated at high temperature to achieve the connection between the two. Here, S101 can be performed once or multiple times, followed by S105, to present a slow heating, so that the amount of melting at different positions tends to be consistent after heating, thereby reducing the situation where the amount of melting is inconsistent due to the thickness of different positions, and thus improving the connection firmness after welding.

[0091] It should be noted that the splicing device in the splicing method provided in this application is similar to the splicing device embodiments described above, and has similar beneficial effects.

The first structural member 11, the second structural member 12, the third structural member 13, and the fourth structural member 14 are connected end to end to form a cuboid-shaped splicing space extending in the vertical direction. The first structural member 11 and the third structural member 13 are opposite each other, the second structural member 12 and the fourth structural member 14 are opposite each other, and the fifth structural member 15 and the sixth structural member are respectively connected to the upper and lower ends of the rectangular frame formed by the first structural member 11, the second structural member 12, the third structural member 13, and the fourth structural member 14, so that the box 10 forms a closed structure, and the box 10 is an opaque box 10. The first structural member 11 and the third structural member 13 are respectively provided with a first channel 111 and a second channel 131 that are opposite to each other; the second structural member 12 and the fourth structural member 14 are respectively provided with a first slide rail 122 extending in the vertical direction and a second slide rail 141 extending in the vertical direction on opposite sides; the fifth structural member 15 is provided with an opening 151 that connects to the splicing space, the hinge seat 16 is connected to the side of the fifth structural member 15 away from the splicing space, and one end of the cover plate 17 is hinged to the hinge seat 16 so that the cover plate 17 can rotate relative to the fifth structural member 15 and cover the opening 151. The cover plate 17 is an opaque part.

[0094] The welding assembly 20 includes a first welding assembly 21 and a second welding assembly 22. The first welding assembly 21 includes a first welding head 211 and a first slider 212. The first slider 212 is connected to a first slide rail 122 and can slide back and forth vertically along the first slide rail 122. The first slider 212 is connected to the first welding head 211. The second welding assembly 22 includes a second welding head 221 and a second slider 222. The second slider 222 is connected to a second slide rail 141 and can slide back and forth vertically along the second slide rail 141. The second slider 222 is connected to the second welding head 221, and the second welding head 221 and the first welding head 211 are opposite to each other and have a gap between them. Both the first slider 212 and the second slider 222 are connected to a first servo motor so that they can move up and down synchronously.

[0095] In this first channel 111, two opposing inner walls are respectively provided with a third slide rail 1111 and a fourth slide rail 1112. Multiple third slide rails 1111 are distributed vertically, and multiple fourth slide rails 1112 are also distributed vertically. The extension directions of both the third and fourth slide rails 1111 and the fourth slide rail 1112 are parallel to the extension direction of the first channel 111. The third slide rail 1111 is slidably connected to a first connecting component 31, and the fourth slide rail 1112 is slidably connected to a second connecting component 32. The first connecting component 31 includes a third slider 311.

The second connecting assembly 32 includes a fourth slider 321, a second clamping part 322 and a second telescopic rod 323. The fourth slider 321 is slidably connected to the fourth slide rail 1112 and connected to the second clamping part 322 through the second telescopic rod 323. The extension and retraction of the first telescopic rod 313 and the second telescopic rod 323 cause the first clamping part 312 and the second clamping part 322, which are opposite to each other, to move closer to each other or further away from each other. The arrangement in the second channel 131 is symmetrical with the arrangement in the first channel 111 about the splicing space. A display touch screen 41 is provided on the outside of the housing 10. The display touch screen 41 is electrically connected to the welding assembly 20, the first connecting assembly 31, the second connecting assembly 32 and the third and fourth connecting assemblies in the second channel 131.

[0096] During assembly:

[0097] First: The first plate to be spliced ​​201 is pressed relative to each other by a first connecting component 31 and a second connecting component 32 to slide into the splicing space within the first channel 111. The second plate to be spliced ​​202 is pressed relative to each other by a third connecting component and a fourth connecting component to slide into the splicing space within the second channel 131. The positions of the first plate to be spliced ​​201 and / or the second plate to be spliced ​​202 are adjusted by sliding so that the seam of the first plate to be spliced ​​201 and the second plate to be spliced ​​202 is aligned between the first weld joint 211 and the second weld joint 221. The remaining first connecting component 31 and the second connecting component 32 are used to clamp the first plate to be spliced ​​201, and the remaining third connecting component and the fourth connecting component are used to clamp the second plate to be spliced ​​202.

[0098] Then: rotate the cover plate 17 so that the cover plate 17 closes the opening 151.

[0099] Finally, the touch screen 41 is activated so that the first welding joint 211 and the second welding joint 221 preheat the joint between the first and second panels to be spliced ​​201 and 202 from top to bottom at half power. Then, the first welding joint 211 and the second welding joint 221 heat the joint between the first and second panels to be spliced ​​201 and 202 from bottom to top at full power. During this process, the clamping force of the first connecting component 31 and the second connecting component 32 on the first panel to be spliced ​​201 is increased, and the clamping force of the third connecting component and the fourth connecting component on the second panel to be spliced ​​202 is increased to maintain better clamping of the first and second panels to be spliced ​​201 and 202.

[0100] In one example: the first splicing board 201 and the second splicing board 202 are both 250mm×250mm×5mm fiber optic panels. After splicing using the above splicing method, a large-size fiber optic panel of 500mm×250mm×5mm is obtained, taking 1 hour. Further machining and polishing yields a 490mm×240mm×4mm fiber optic panel with a vacuum tightness of less than 10. -12 Pa·m 3 / s, with shear distortion of 5μm and serpentine distortion of 5μm at the splicing point, so as to connect the two fiber optic panels together without affecting the switching imaging effect.

[0101] In another example, both the first splicing board 201 and the second splicing board 202 are 400mm×400mm×5mm fiber optic panels. After splicing using the above method, a large-size fiber optic panel of 800mm×400mm×5mm is obtained, taking 1.3 hours. Further machining and polishing yield a 780mm×360mm×4mm fiber optic panel with a vacuum tightness of less than 10. -12 Pa·m 3 / s, with shear distortion of 9μm and serpentine distortion of 12μm at the splicing point, so as to connect the two fiber optic panels together without affecting the switching imaging effect.

[0102] In another example, both the first splicing board 201 and the second splicing board 202 are 800mm × 800mm × 5mm fiber optic panels. After splicing using the above method, a large-size fiber optic panel of 1600mm × 800mm × 5mm is obtained, taking 1.5 hours. Further machining and polishing yield a 1530mm × 710mm × 4mm fiber optic panel with a vacuum tightness of less than 10. -12 Pa·m 3 / s, with shear distortion of 7μm and serpentine distortion of 16μm at the splicing point, so as to connect the two fiber optic panels together without affecting the switching imaging effect.
