[0004] In the prior art, to avoid collisions between curved glass surfaces, a placement fixture similar to that disclosed in Chinese Utility Model Patent Publication No. CN221679271U is used to store the curved glass surfaces.
[0005] However, the existing handling devices mentioned above are not suitable for high-speed automated feeding and stacking of photovoltaic curved glass on automated production lines. Utility Model Content
[0006] To address the problems that existing handling devices are unsuitable for high-speed automated feeding and stacking of photovoltaic curved glass, and that photovoltaic curved glass is easily damaged, the purpose of this utility model is to provide a photovoltaic curved glass handling device.
[0007] The technical solution provided by this utility model is as follows:
[0008] In a first aspect, a photovoltaic curved glass handling device includes a placement fixture and a feeding mechanism;
[0009] The placement fixture has an upper end face and a lower end face;
[0010] Take a spatial rectangular coordinate system O-XYZ. The upper end face of the fixture has upper curved surfaces on both sides along the X direction, and the lower end face of the fixture has lower curved surfaces on both sides along the X direction. The upper curved surfaces and the lower curved surfaces have the same orientation.
[0011] The feeding mechanism is used to transport photovoltaic curved glass and placement fixtures along the Y and Z directions, and to feed / stack the photovoltaic curved glass and placement fixtures in sequence;
[0012] When the photovoltaic curved glass and the placement fixture are stacked in sequence, the upper curved surface is used to fit with the rolled outer curved surface of the photovoltaic curved glass, and the lower curved surface is used to fit with the rolled inner curved surface of the photovoltaic curved glass.
[0013] As an optional technical solution in the first aspect, the dimension of the placement fixture in the Z direction is H1, and the dimension of the rolled edge in the Z direction is H2, wherein H1 > H2.
[0014] Alternatively, H2 = (1 / 2 to 2 / 3)H1.
[0015] As an optional technical solution in the first aspect, the upper end face of the tooling is parallel to the lower end face of the tooling and parallel to the OXY plane; the upper end face of the tooling is used to fit with the lower end face of the photovoltaic curved glass; the lower end face of the tooling is used to fit with the upper end face of the photovoltaic curved glass.
[0016] Optionally, the fixture is provided with fixture sides on both sides along the X direction, which are used to fit with the inner side of the photovoltaic curved glass; the fixture sides are parallel to the OZY plane.
[0017] As an optional technical solution in the first aspect, the size of the placement fixture in the Y direction is not less than the size of the photovoltaic curved glass in the Y direction.
[0018] As an optional technical solution of the first aspect, the feeding mechanism includes a Y-guide rail, on which at least one pair of Z-guide rails are installed, and the pair of Z-guide rails includes a first Z-guide rail and a second Z-guide rail; a first picking-up component is installed on the first Z-guide rail, and a second picking-up component is installed on the second Z-guide rail.
[0019] It also includes a first Y-axis driving component, a second Y-axis driving component, a first Z-axis driving component, and a second Z-axis driving component; the first Y-axis driving component and the second Y-axis driving component are respectively used to drive the first Z-axis guide rail and the second Z-axis guide rail to move along the Y-axis guide rail; the first Z-axis driving component and the second Z-axis driving component are respectively used to drive the first material picking component and the second material picking component to move along the first Z-axis guide rail and the second Z-axis guide rail.
[0020] Optionally, the first material handling component includes a first bracket on which a plurality of tooling suction cups are mounted; the second material handling component includes a second bracket on which a plurality of photovoltaic curved glass suction cups are mounted.
[0021] Compared with the prior art, the technical solution provided by this utility model has the following advantages:
[0022] The placement fixture proposed in this utility model has an upper curved surface and a lower curved surface, which can protect the outer and inner curved surfaces of the rolled edges of the photovoltaic curved glass, preventing the rolled edges from breaking at the bends. Simultaneously, the placement fixture only has upper and lower curved surfaces on both sides along the X-direction, with no obstructions in the Z and Y directions. In this case, the feeding mechanism only needs to transport the photovoltaic curved glass and place the fixture along the Y and Z directions to achieve the simultaneous transport of the photovoltaic curved glass, feeding, and stacking. This not only reduces the movement of the feeding mechanism, improving the feeding and stacking speed, but also prevents damage to the rolled edges of the photovoltaic curved glass due to X-direction movement.
[0023] In addition, since the dimensions of the placement fixture in the Z-direction are larger than those of the rolled edge in the Z-direction, and the rolled edge can be used to achieve X-direction limiting, it is beneficial for the batch feeding and stacking of photovoltaic curved glass and placement fixtures.

[0038] like Figure 4 As shown, the photovoltaic curved glass 200 has an upper surface 201 and a lower surface 202, which are approximately parallel. The photovoltaic curved glass 200 has rolled edges on both sides along the X-direction, with the rolled edges curving upwards towards the upper surface 201. The inner side of the rolled edge is adjacent to the upper surface 201, and an inner curved surface 204 is provided on the inner side of the rolled edge. The inner curved surface 204 smoothly transitions tangentially to the upper surface 201 of the photovoltaic curved glass. An inner edge 203 is also provided on the inner side of the rolled edge, which also smoothly transitions tangentially to the inner curved surface 204. The inner edge 203 is approximately perpendicular to the upper surface 201 of the photovoltaic curved glass.
[0039] The outer side of the rolled edge is adjacent to the lower end surface 202 of the photovoltaic curved glass. The outer side of the rolled edge is provided with an outer rolled edge curved surface 205, which smoothly transitions tangentially to the lower end surface 202 of the photovoltaic curved glass.
[0040] In one embodiment, such as Figure 1 As shown, this application proposes a photovoltaic curved glass handling device, including a placement fixture 100 and a feeding mechanism. For ease of orientation indication, a spatial rectangular coordinate system O-XYZ is used.
[0041] Specifically, such as Figure 2-3 As shown, the fixture 100 has an upper end face 101 and a lower end face 102. The upper end face 101 and the lower end face 102 are parallel, that is, parallel to the OXY plane. Figure 6As shown, when the placement fixture 100 and the photovoltaic curved glass 200 are stacked sequentially on the tray 302, the bearing surface of the tray 302 is parallel to the OXY plane. At this time, the upper end face 101 and lower end face 102 of the fixture, the upper end face 201 and lower end face 202 of the photovoltaic curved glass are all parallel to the OXY plane. The placement fixture 100 is placed between two adjacent photovoltaic curved glass pieces 200. At this time, the upper end face 101 of the fixture is in contact with the lower end face 202 of the photovoltaic curved glass, and the lower end face 102 of the fixture is in contact with the upper end face 201 of the photovoltaic curved glass. It can be understood that the placement fixture 100 and the photovoltaic curved glass 200 placed on the tray 302 are horizontally placed, not tilted. Because the placement fixture 100 and the photovoltaic curved glass 200 in the tilted state tend to move towards the tilted side, this will compress the rolled edges of the photovoltaic curved glass 200, which can easily lead to edge damage. Therefore, the horizontal placement fixture 100 and photovoltaic curved glass 200 can avoid damage and edge curling.
[0042] To further protect the rolled edges of the photovoltaic curved glass 200, in this embodiment, the upper end face 101 of the fixture has upper curved surfaces 104 on both sides along the X direction, and the upper curved surfaces 104 smoothly transition tangentially to the upper end face 101 of the fixture. The lower end face 102 of the fixture also has lower curved surfaces 105 on both sides along the X direction, and the lower curved surfaces 105 smoothly transition tangentially to the lower end face 102 of the fixture.
[0043] It should be noted that the upper curved surface 104 and the lower curved surface 105 face the same direction. In this embodiment, both the upper curved surface 104 and the lower curved surface 105 face the upper end face 101 of the placement fixture. When the photovoltaic curved glass 200 and the placement fixture 100 are stacked sequentially, the placement fixture 100 separates the upper and lower adjacent photovoltaic curved glass 200s to prevent collisions and damage between the photovoltaic curved glass 200s. The upper curved surface 104 is in contact with the rolled outer curved surface 205 of the photovoltaic curved glass 200, and the lower curved surface 105 is in contact with the rolled inner curved surface 204 of the photovoltaic curved glass 200. Since the upper curved surface 104 and the lower curved surface 105 can protect the rolled outer curved surface 205 and the rolled inner curved surface 204 from damage due to impacts, they can also provide support for the rolled edges, thereby preventing the rolled edges from breaking.
[0044] like Figure 2-6 As shown, the placement fixture 100 has an upper curved surface 104 and a lower curved surface 105 in the X direction, which will form a limiting effect in the X direction, while there is no limiting effect in the Z and Y directions. The placement fixture 100 and the photovoltaic curved glass 200 can be moved directly in the Y and Z directions, and stacking and splitting in the Y and Z directions can be easily realized.
[0045] Specifically, such as Figure 1As shown, the feeding mechanism can transport the photovoltaic curved glass 200 and the placement fixture 100 along the Y and Z directions, and allow the photovoltaic curved glass 200 and the placement fixture 100 to be fed / stacked sequentially.
[0046] When stacking photovoltaic curved glass 200, first place tray 302. The feeding mechanism first transports the first photovoltaic curved glass 200 onto tray 302 along the Y and Z directions. Then, the feeding mechanism transports the first placement fixture 100 along the Y and Z directions and places it on the first photovoltaic curved glass 200. The feeding mechanism then places the second photovoltaic curved glass 200 onto the first placement fixture 100, and then places the second placement fixture 100, and so on, completing the stacking process sequentially. When disassembling, the placement fixture 100 and the photovoltaic curved glass 200 are removed sequentially from top to bottom along the Y and Z directions.
[0047] During the loading process, the stacked placement fixture 100 and photovoltaic curved glass 200 are placed in the set position, and the loading mechanism removes the placement fixture 100 and photovoltaic curved glass 200 from top to bottom in sequence.
[0048] In one alternative implementation scheme, such as Figure 5 As shown, the placement fixture 100 has a dimension of H1 in the Z direction and a rolled edge dimension of H2 in the Z direction, where H1 > H2. At this time, two adjacent photovoltaic curved glass panels 200 in the Y direction (i.e., the up-down direction) will be separated by a distance by the placement fixture 100, thus preventing collisions between the two adjacent photovoltaic curved glass panels 200, especially preventing collisions between the rolled edges of the two adjacent photovoltaic curved glass panels 200.
[0049] Preferably, H2 = (1 / 2 to 2 / 3)H1. After the photovoltaic curved glass 200 and the placement fixture 100 are stacked layer by layer, the center of gravity is relatively high. The rolled edges can form a limiting effect in the X direction, which can reduce the risk of the stacked photovoltaic curved glass 200 and the placement fixture 100 tipping over in the X direction to a certain extent.
[0050] In one alternative implementation scheme, such as Figure 2-3 As shown, the placement fixture 100 is also provided with fixture side edges 103 on both sides along the X direction, and the lower curved surface 105 smoothly transitions tangentially to the fixture side edges 103. When the placement fixture 100 and the photovoltaic curved glass 200 are stacked in sequence, the fixture side edges 103 are in contact with the inner side edges 203 of the photovoltaic curved glass 200, that is, at this time, a support can be formed on the inner side of the rolled edge of the photovoltaic curved glass 200 to prevent the rolled edge from breaking.
[0051] Specifically, the tooling side 103 is parallel to the OZY plane, that is, perpendicular to the OXY plane. This ensures that stacking and removing the photovoltaic curved glass 200 and placing the tooling 100 along the Z-axis is unobstructed. Since the tooling side 103 is vertical, it also avoids creating oblique pressure on the rolled edge, thus preventing damage to the rolled edge.
[0052] As an optional embodiment, the size of the fixture 100 in the Y direction is not less than the size of the photovoltaic curved glass 200 in the Y direction, that is, the size of the fixture 100 in the Y direction is greater than the size of the photovoltaic curved glass 200 in the Y direction, or the size of the fixture 100 in the Y direction is equal to the size of the photovoltaic curved glass 200 in the Y direction, so as to prevent the photovoltaic curved glass 200 from bulging in the Y direction. The fixture 100 in the Y direction can protect the photovoltaic curved glass 200.
[0053] For the feeding mechanism, as an optional embodiment, such as Figure 1 As shown, the feeding mechanism includes two Y-guide rails 301, which are arranged alternately in the Z direction.
[0054] At least one pair of Z-guide rails are mounted on the Y-guide rail 301. The figure shows a pair of Z-guide rails, including a first Z-guide rail 311 and a second Z-guide rail 321. The first Z-guide rail 311 and the second Z-guide rail 321 are arranged alternately along the Y-direction. A first picking component is mounted on the first Z-guide rail 311, and a second picking component is mounted on the second Z-guide rail 321. The first picking component can carry one placement fixture 100 at a time, and the second picking component can carry one photovoltaic curved glass 200 at a time.
[0055] The feeding mechanism also includes a first Y-axis driving component 310, a second Y-axis driving component 320, a first Z-axis driving component 312, and a second Z-axis driving component 322. The first Y-axis driving component 310 and the second Y-axis driving component 320 are respectively used to drive the first Z-axis guide rail 311 and the second Z-axis guide rail 321 to move along the Y-axis guide rail 301. The first Z-axis driving component 312 and the second Z-axis driving component 322 are respectively used to drive the first picking component and the second picking component to move along the first Z-axis guide rail 311 and the second Z-axis guide rail 321. The first Y-axis driving component 310, the second Y-axis driving component 320, the first Z-axis driving component 312, and the second Z-axis driving component 322 are relatively mature in the prior art and will not be described or limited further here.
[0056] Specifically, the first material handling component includes a first support 313, on which several tooling suction cups 314 are mounted. The second material handling component includes a second support 323, on which several photovoltaic curved glass suction cups 324 are mounted. In this embodiment shown in the figure, there are four tooling suction cups 314 and four photovoltaic curved glass suction cups 324, roughly corresponding to the four corners of the upper end face 101 of the tooling and the upper end face 201 of the photovoltaic curved glass. The tooling suction cups 314 and the photovoltaic curved glass suction cups 324 can adsorb and place the tooling 100 and the photovoltaic curved glass 200, thereby allowing the adsorbed tooling 100 and photovoltaic curved glass 200 to be transported by the feeding mechanism along the Y and Z directions. After the placement fixture 100 and the photovoltaic curved glass 200 are moved to the set position, the fixture suction cup 314 and the photovoltaic curved glass suction cup 324 can also be released from the placement fixture 100 and the photovoltaic curved glass 200.
[0057] For the tooling suction cup 314 and the photovoltaic curved glass suction cup 324, the existing technologies are relatively mature, such as the use of vacuum suction cups, so they will not be elaborated or limited here.
[0058] It should be noted that the feeding mechanism is not limited to the above implementation scheme. Other existing mechanisms that can realize the Y-axis and Z-axis handling and placement of the tooling 100 and the photovoltaic curved glass 200 are also applicable to this application, and will not be described in detail here.
[0059] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
