Description

Technical Field

[0001] The present invention belongs to the technical field of curved glass forming, and in particular relates to a detachable arc-changing device and curved glass forming equipment. Background Art

[0002] Currently, in the field of curved glass forming technology, the radius of curvature of curved glass is constrained by the arc length of the curved glass production equipment's arc-changing mechanism, influenced by various objective factors and production processes. For example, the curvature radius performance achieved by conventional large-arc-length curved glass forming equipment is limited by the equipment's arc center angle being less than 180 degrees. For curved glass forming equipment with an arc length L, the minimum curvature radius R is R ≥ λ•L / π (λ is the safety factor, L is the arc length, typically 0.75-0.9, and π is pi, typically 3.14). If the curvature radius R is less than λ•L / π, the typical approach is to purchase a new curved glass forming unit with a smaller arc length, increasing production costs and the investment in space, personnel, and other aspects.

[0030] Furthermore, the terms "first," "second," and the like are primarily used to distinguish different devices, elements, or components (which may or may not be the same in type and configuration) and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated.

[0031] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0032] Example 1 See Figures 1 to 8 The present invention discloses a detachable arc-changing device, comprising: a frame 10; x arc-changing sub-units 20, wherein the x arc-changing sub-units 20 are sequentially arranged along the glass conveying direction, where x is a natural number and x≥2; the x arc-changing sub-units 20 can be detachably connected to form a total arc-changing unit 30, or the total arc-changing unit 30 can be disassembled to obtain y arc-changing sub-units 20, where y is a natural number and y≥2; x and y are equal or unequal.

[0033] In the detachable arc-changing device of the present invention, x arc-changing sub-units 20 can be detachably connected to form a total arc-changing unit 30, or the total arc-changing unit 30 can be disassembled to obtain y arc-changing sub-units 20, so that the arc-changing sub-units 20 of the target length can be disassembled according to actual needs, and the arc-changing sub-units 20 of smaller length can be used to produce curved glass with a smaller curvature radius, and the arc-changing sub-units 20 or the total arc-changing unit 30 of larger length can also be used to produce curved glass with a larger curvature radius, realizing "one machine with multiple functions".

[0034] It should be noted that the length of the arc-changing sub-unit 20 refers to the length of the arc-changing sub-unit 20 when it is in a flattened state, and the length of the arc-changing total unit 30 refers to the length of the arc-changing total unit 30 when it is in a flattened state.

[0035] The smaller the length of the arc-changing sub-unit 20 in the flattened state, the smaller the arc length of the arc-changing sub-unit 20 in the arc-changing state, the smaller the length of the arc-changing total unit 30 in the flattened state, and the smaller the arc length of the arc-changing total unit 30 in the arc-changing state; according to the curvature radius R≥λ•L / π, since the curvature radius R is positively correlated with the arc length L, the smaller the arc length L, the smaller the corresponding curvature radius R that can be achieved.

[0036] Since the curved glass is pressed and formed in the arc-changing sub-unit 20, the smaller the curvature radius of the arc-changing sub-unit 20, the smaller the curvature radius of the formed curved glass; or the curved glass is pressed and formed in the arc-changing total unit 30, the smaller the curvature radius of the arc-changing total unit 30, the smaller the curvature radius of the formed curved glass.

[0037] Since x and y are equal or unequal, for example, when x=4 and y=2, the total arc changing unit 30 formed by detachably connecting x arc changing sub-units 20 can be disassembled into 2 arc changing sub-units 20 to flexibly adapt to different size requirements.

[0038] In an embodiment of the present invention, the detachable arc-changing device also includes a driving unit 40, which includes an upper driving structure 401 and a lower driving structure 402; when x arc-changing sub-units 20 are detachably connected to form a total arc-changing unit 30, the total arc-changing unit 30 is correspondingly provided with a driving unit 40; when the total arc-changing unit 30 is disassembled to obtain y arc-changing sub-units 20, each arc-changing sub-unit 20 is correspondingly provided with a driving unit 40.

[0039] In an embodiment of the present invention, when x arc-changing sub-units 20 are detachably connected to form a total arc-changing unit 30, the total arc-changing unit 30 includes a corresponding upper arc-changing total mechanism 301 and a lower arc-changing total mechanism 302; the upper arc-changing total mechanism 301 is formed by detachably connecting x upper arc-changing sub-mechanisms 201, and the upper arc-changing total mechanism 301 is detachably connected to the corresponding upper driving structure 401, and the upper driving structure 401 drives the upper arc-changing total mechanism 301 to change the arc; the lower arc-changing total mechanism 302 is formed by detachably connecting x lower arc-changing sub-mechanisms 202, and the lower arc-changing total mechanism 302 is detachably connected to the corresponding lower driving structure 402, and the lower driving structure 402 drives the lower arc-changing total mechanism 302 to change the arc.

[0040] In an embodiment of the present invention, when the total arc-changing unit 30 is disassembled to obtain y arc-changing sub-units 20, the arc-changing sub-unit 20 includes a corresponding upper arc-changing sub-mechanism 201 and a lower arc-changing sub-mechanism 202; the upper arc-changing sub-mechanism 201 is detachably connected to the corresponding upper driving structure 401, and the upper driving structure 401 drives the upper arc-changing sub-mechanism 201 to change the arc; the lower arc-changing sub-mechanism 202 is detachably connected to the corresponding lower driving structure 402, and the lower driving structure 402 drives the lower arc-changing sub-mechanism 202 to change the arc.

[0041] In an embodiment of the present invention, when the upper arc-changing main mechanism 301 and the lower arc-changing main mechanism 302 are both in a flattened state, the length of the upper arc-changing main mechanism 301 is N, and the length of the lower arc-changing main mechanism 302 is M; when y upper arc-changing sub-mechanisms 201 and y lower arc-changing sub-mechanisms 202 are both in a flattened state, the length of the first upper arc-changing sub-mechanism 201 is N1, and the length of the first lower arc-changing sub-mechanism 202 is M1...the length of the y-th upper arc-changing sub-mechanism 201 is Ny, and the length of the y-th lower arc-changing sub-mechanism 202 is My; N1<N, Ny<N, N1+……Ny≤N; M1<M, My<M, M1+……My≤M.

[0042] It should be noted that when y=2, the length of the first upper arc-changing sub-mechanism 201 is N1, the length of the first lower arc-changing sub-mechanism 202 is M1, the length of the second upper arc-changing sub-mechanism 201 is N2, and the length of the second lower arc-changing sub-mechanism 202 is M2; N1<N, N2<N, N1+N2≤N; M1<M, M2<M, M1+M2≤M.

[0043] When y=3, the length of the first upward arc-changing sub-mechanism 201 is N1, the length of the first downward arc-changing sub-mechanism 202 is M1, the length of the second upward arc-changing sub-mechanism 201 is N2, the length of the second downward arc-changing sub-mechanism 202 is M2, the length of the third upward arc-changing sub-mechanism 201 is N3, and the length of the third downward arc-changing sub-mechanism 202 is M3; N1<N, N2<N, N3<N, N1+N2+N3≤N; M1<M, M2<M, M3<M, M1+M2+M3≤M.

[0044] See Figure 3 as well as Figure 4 , y=4, wherein the length of the first upward arc-changing sub-mechanism 201 is N1, wherein the length of the first downward arc-changing sub-mechanism 202 is M1, wherein the length of the second upward arc-changing sub-mechanism 201 is N2, wherein the length of the second downward arc-changing sub-mechanism 202 is M2, wherein the length of the third upward arc-changing sub-mechanism 201 is N3, wherein the length of the third downward arc-changing sub-mechanism 202 is M3, wherein the length of the fourth upward arc-changing sub-mechanism 201 is N4, wherein the length of the fourth downward arc-changing sub-mechanism 202 is M4; N1<N, N2<N, N3<N, N4<N, N1+ N2+N3+N4≤N; M1<M, M2<M, M3<M, M4<M, M1+M2+M3+M4≤M.

[0045] In an embodiment of the present invention, the upper arc-changing sub-mechanism 201 includes a first upper connecting member 2011 and a second upper connecting member 2012, and multiple first upper connecting members 2011 are sequentially arranged along the glass conveying direction. Two adjacent first upper connecting members 2011 are rotatably connected, and two adjacent first upper connecting members 2011 are also rotatably connected and slidably connected with at least one second upper connecting member 2012, and the two adjacent first upper connecting members 2011 and the first upper connecting member 2011 and the second upper connecting member 2012 are both detachably connected; the lower arc-changing sub-mechanism 202 includes a first lower connecting member 2021 and a second lower connecting member 2022, and multiple first lower connecting members 2021 are sequentially arranged along the glass conveying direction, and two adjacent first lower connecting members 2021 are rotatably connected, and two adjacent first lower connecting members 2021 are also rotatably connected and slidably connected with at least one second lower connecting member 2022, and the two adjacent first lower connecting members 2021 and the first lower connecting member 2021 and the second lower connecting member 2022 are both detachably connected.

[0046] Since the distance N0 between the two rotation centers of the first upper connecting member 2011 remains unchanged when the upper arc-changing mechanism 301 is in the flattened state or the arc-changing state, Figure 6 Therefore, when the upper arc-changing mechanism 301 is in the arc-changing state, the value of the arc length L of the upper arc-changing mechanism 301 is also N; when the lower arc-changing mechanism 302 is in the flattened state or the arc-changing state, the distance M0 between the two rotation centers of the first lower connecting member 2021 remains unchanged, see Figure 8 Therefore, when the lower arc-changing total mechanism 302 is in the arc-changing state, the value of the arc length L of the lower arc-changing total mechanism 302 is also M.

[0047] Similarly, since the distance N0 between the two rotation centers of the first upper connecting member 2011 remains unchanged when the first upper arc-changing sub-mechanism 201 is in the flattened state or the arc-changing state, the value of the arc length L of the first upper arc-changing sub-mechanism 201 is also N1 when the first upper arc-changing sub-mechanism 201 is in the arc-changing state; when the first lower arc-changing sub-mechanism 202 is in the flattened state or the arc-changing state, the distance M0 between the two rotation centers of the first lower connecting member 2021 remains unchanged, so when the first lower arc-changing sub-mechanism 202 is in the arc-changing state, the value of the arc length L of the first lower arc-changing sub-mechanism 202 is also M1.

[0048] Similarly, if the length of the yth upper arc-changing sub-mechanism 201 is Ny, then the value of the arc length L of the yth upper arc-changing sub-mechanism 201 is also Ny, and if the length of the yth lower arc-changing sub-mechanism 202 is My, then the value of the arc length L of the yth lower arc-changing sub-mechanism 202 is also My.

[0049] Therefore, the smaller the length of the upper arc-changing total mechanism 301 in the flattened state, that is, the smaller the arc length of the upper arc-changing total mechanism 301 in the arc-changing state, the smaller the length of the lower arc-changing total mechanism 302 in the flattened state, that is, the smaller the arc length of the lower arc-changing total mechanism 302 in the arc-changing state; the smaller the length of the upper arc-changing sub-mechanism 201 in the flattened state, that is, the smaller the arc length of the upper arc-changing sub-mechanism 201 in the arc-changing state, the smaller the length of the lower arc-changing sub-mechanism 202 in the flattened state, that is, the smaller the arc length of the lower arc-changing sub-mechanism 202 in the arc-changing state; according to the curvature radius R≥λ•L / π, since the curvature radius R is positively correlated with the arc length L, the smaller the arc length L is, the smaller the corresponding curvature radius R that can be achieved.

[0050] After determining the length of the upper arc-changing sub-mechanism 201 in the flattened state, that is, after determining the arc length of the upper arc-changing sub-mechanism 201 in the arc-changing state, the upper driving structure 401 is used to control the arc center angle of the upper arc-changing sub-mechanism 201 to obtain the upper arc-changing sub-mechanism 201 with a target curvature radius; after determining the length of the lower arc-changing sub-mechanism 202 in the flattened state, that is, after determining the arc length of the lower arc-changing sub-mechanism 202 in the arc-changing state, the lower driving structure 402 is used to control the arc center angle of the lower arc-changing sub-mechanism 202 to obtain the lower arc-changing sub-mechanism 202 with a target curvature radius.

[0051] Similarly, after determining the length of the upper arc-changing mechanism 301 in the flattened state, that is, after determining the arc length of the upper arc-changing mechanism 301 in the arc-changing state, the upper driving structure 401 is used to control the arc center angle of the upper arc-changing mechanism 301 to obtain the upper arc-changing mechanism 301 with a target curvature radius; after determining the length of the lower arc-changing mechanism 302 in the flattened state, that is, after determining the arc length of the lower arc-changing mechanism 302 in the arc-changing state, the lower driving structure 402 is used to control the arc center angle of the lower arc-changing mechanism 302 to obtain the lower arc-changing mechanism 302 with a target curvature radius.

[0052] For example, see Figures 5 to 8 The first upper connecting member 2011 and the first lower connecting member 2021 are both rigid T-shaped plates, and the second upper connecting member 2012 and the second lower connecting member 2022 are both rigid connecting rods.

[0053] A scissor-type four-bar linkage is formed by a cross-arrangement between multiple second upper connecting members 2012, and the second upper connecting members 2012 can assist the first upper connecting member 2011 in the upper arc changing area to rotate relatively stably, further improving the stability and accuracy of the arc changing; a scissor-type four-bar linkage is formed by a cross-arrangement between multiple second lower connecting members 2022, and the second lower connecting members 2022 can assist the first lower connecting member 2021 in the lower arc changing area to rotate relatively stably, further improving the stability and accuracy of the arc changing.

[0073] It should be noted that the upper driving structure 401 is detachably connected to the upper lifting frame 101 through a screw and nut structure, and the lower driving structure 402 is detachably connected to the upper fixing frame 103 through a screw and nut structure; the middle part of the upper arc changing mechanism 301 or the middle part of the upper arc changing sub-mechanism 201 can be detachably connected to the first end of the hanging plate 102 through a screw and nut structure, and the second end of the hanging plate 102 is detachably connected to the upper lifting frame 101 through a screw and nut structure.

[0074] See Figures 1 to 4 The upper driving structure 401 and the hanging plate 102 can move up and down following the upper lifting frame 101, so that the upper arc changing mechanism 301 and the upper arc changing sub-mechanism 201 can move up and down as a whole, making it easier for the roller 2023 to transport the finished glass to the next workstation.

[0075] It should be noted that how the upper lifting frame 101 is lifted up and down is an existing technology and will not be elaborated here. For example, the upper lifting frame 101 includes a frame body and a lifting cylinder. The lifting cylinder drives the frame body to move up and down, thereby driving the upper drive structure 401 and the hanging plate 102 to move up and down, and then driving the upper arc changing mechanism 301 and the upper arc changing sub-mechanism 201 to move up and down.

[0077] Example 2 See Figures 1 to 8 The present invention discloses a curved glass forming device, including the above-mentioned detachable arc-changing device.

[0078] The curved glass forming equipment of the present invention includes the above-mentioned detachable arc-changing device, which can use a smaller length arc-changing sub-unit 20 to produce curved glass with a smaller curvature radius, and can also use a larger length arc-changing sub-unit 20 or an arc-changing total unit 30 to produce curved glass with a larger curvature radius.

[0079] The process of forming curved glass using the arc-changing sub-unit 20 is as follows: 1. The arc changing unit 30 is disassembled to obtain y arc changing sub-units 20 of target length; 2. The y upper arc-changing sub-mechanisms 201 move upward and separate from the corresponding lower arc-changing sub-mechanisms 202. At this time, the upper arc-changing sub-mechanisms 201 and the lower arc-changing sub-mechanisms 202 are both in a flattened state. Y glasses are sequentially transported from the heating furnace to the lower arc-changing sub-mechanisms 202 of the curved glass forming equipment. The roller 2023 rotates to transport the glass to the predetermined position of the lower arc-changing sub-mechanism 202 and then stops rotating. 3. In the arc-changing sub-unit 20, the upper driving structure 401 is used to control the arc center angle of the upper arc-changing sub-mechanism 201 to obtain the upper arc-changing sub-mechanism 201 with a target curvature radius, and the lower driving structure 402 is used to control the arc center angle of the lower arc-changing sub-mechanism 202 to obtain the lower curvature radius; 4. After all y arc-changing sub-units 20 have completed adjustment of the curvature radius, all y upper arc-changing sub-mechanisms 201 move downward to press the glass against the corresponding lower arc-changing sub-mechanisms 202 for shaping. After the glass is formed, the curved glass with the target curvature radius is obtained. Then, the y upper arc-changing sub-mechanisms 201 move upward and separate from the corresponding lower arc-changing sub-mechanisms 202. 5. In the arc-changing sub-unit 20, the upper driving structure 401 is used to drive the upper arc-changing sub-mechanism 201 to a flattened state, and the lower driving structure 402 is used to drive the lower arc-changing sub-mechanism 202 to a flattened state. The roller 2023 rotates to transport the curved glass with the target curvature radius to the next workstation.

[0080] The process of forming curved glass using the arc-changing unit 30 is as follows: 1. X arc-changing sub-units 20 are detachably connected to form an arc-changing main unit 30; 2. The upper arc-changing mechanism 301 moves upward and separates from the corresponding lower arc-changing mechanism 302. At this time, the upper arc-changing mechanism 301 and the lower arc-changing mechanism 302 are both in a flat state. The glass is transported from the heating furnace to the lower arc-changing mechanism 302 of the curved glass forming equipment. The roller 2023 rotates to transport the glass to a predetermined position of the lower arc-changing mechanism 302 and then stops rotating. 3. In the arc-changing unit 30, the upper driving structure 401 is used to control the arc center angle of the upper arc-changing mechanism 301 to obtain the target curvature radius of the upper arc-changing mechanism 301, and the lower driving structure 402 is used to control the arc center angle of the lower arc-changing mechanism 302 to obtain the target curvature radius of the lower arc-changing mechanism 302; 4. After the arc changing unit 30 completes the adjustment of the curvature radius, the upper arc changing mechanism 301 moves downward to press the glass against the corresponding lower arc changing mechanism 302 for forming. After the glass is formed, the curved glass with the target curvature radius is obtained. The upper arc changing mechanism 301 moves upward to separate from the corresponding lower arc changing mechanism 302. 5. In the arc changing unit 30, the upper driving structure 401 is used to drive the upper arc changing mechanism 301 to a flattened state, and the lower driving structure 402 is used to drive the lower arc changing mechanism 302 to a flattened state. The roller 2023 rotates to transport the curved glass with the target curvature radius to the next workstation.
