Description

Technical Field

[0001] The present invention relates to the field of liquid crystal display panel production, and in particular to a multi-size common turnover pallet. Background Art

[0002] There are display panels of various sizes in the existing technology, so there are many corresponding pallet models; and the requirements of each model product at each stage are different, which leads to stagnation of factory turnover pallets and occupies storage costs; when the production capacity of a certain model is temporarily increased, the number of existing pallets cannot meet the turnover demand, and corresponding pallets need to be purchased urgently. The subsequent decline in production capacity will cause a large number of pallets to be on hold; and due to long-term stagnation, when the anti-static capacity cannot be met, the pallets can only be scrapped directly, which leads to increased production costs. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a turnover pallet that can be shared by multiple sizes. By pre-setting a sink groove on the main pallet and matching it with foam limiters, it is suitable for the production of panels of different sizes. There is no need to purchase pallets of different models, which reduces mold opening costs and saves production costs. The foam position can also be switched according to production needs to correspond to production of different sizes, thereby improving the utilization rate of turnover pallets.

[0009] In one embodiment, the first preset grooves are symmetrically arranged at least along the width direction of the product carrying surface, and second preset grooves are symmetrically provided on both sides of the protruding portion of the convex PCB component avoidance area.

[0010] In one embodiment, the sub-preset sinks have the same depth and the same size.

[0011] In one embodiment, the limiting foam is EVA foam with a foaming rate of 10 times, and is fixed in the sub-preset sink by a high-temperature resistant adhesive.

[0012] In one embodiment, the tray body is made of ABS material with a thickness of 1.0 to 2.0 mm.

[0013] In one embodiment, a tray inner groove limiter is provided around the product carrying surface, and the preset sink is provided in an area formed by the tray inner groove limiter.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, as long as no conflict exists, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the resulting technical solutions are all within the scope of protection of the present invention.

[0033] Parts not described in the present invention can be implemented by adopting or drawing on existing technologies.

[0034] like Figure 1 As shown, the multi-size common turnover pallet of the present invention includes a pallet body 1 and a frame 7 arranged on the edge of the pallet body. The pallet body 1 includes a product carrying surface 2, and at least one group of preset grooves 3 are symmetrically arranged on the outer side of the product carrying surface 2. Each group of preset grooves 3 includes at least two sub-preset grooves 31, and the adjacent sub-preset grooves 31 are connected to each other. A limiting foam 4 is arranged in the preset groove 3.

[0035] The multi-size shared turnover pallet of the present invention is suitable for the production of panels of different sizes by pre-setting the sink groove 3 on the pallet body 1 and matching it with foam limiters. There is no need to purchase pallets of different models, which reduces mold opening costs and saves production costs. The foam position can also be switched according to production needs to correspond to production of different sizes, thereby improving the utilization rate of the turnover pallet.

[0036] In a specific embodiment, the preset sink 3 includes a first preset sink, and each group of the first preset sink includes at least three sub-preset sinks 31. The sub-preset sinks 31 are rectangular, and the rectangular symmetry axes of adjacent sub-preset sinks 31 intersect with each other. Figure 1 As mentioned above, the three sub-preset sinks 31 whose rectangular symmetry axes intersect with each other can be arranged in a shape similar to an inverted T.

[0037] The interconnected design between adjacent sub-preset sinks is conducive to the blister forming of turnover trays made of ABS material, preventing the gaps between the preset sinks from being too small, which would cause the blister forming process to fail; it also provides working space for removing excess foam when switching between machine models.

[0038] Continue to refer Figure 1 In an optional embodiment, the preset sink 3 also includes a second preset sink, and each group of second preset sinks includes at least four sub-preset sinks 31. The sub-preset sinks 31 are rectangular and arranged in a tree-like manner. Adjacent sub-preset sinks 31 are connected at the diagonals.

[0039] The vertex of the first preset groove of the inverted T-shaped shape is close to the midpoint of the width direction of the turnover pallet or the pallet body 1. Compared with the vertex of the first preset groove, the vertex of the second preset groove is closer to the midpoint of the width direction of the turnover pallet or the pallet body 1 (i.e., at the midpoint of the width direction of the turnover pallet or the pallet body 1). Figure 1The apex of the second preset sink groove is lower than the apex of the first preset sink groove). The width direction of the turnover pallet or the pallet body refers to Figure 1 The vertical direction in the turnover pallet or the length direction of the pallet body refers to Figure 1 Horizontal direction in .

[0040] In an optional embodiment, the depth of the preset groove 3 is 1.5 to 2 mm. Preferably, the preset depth of the groove 3 is 2 mm, which can effectively prevent the panel from being stuck to glue when moving in the tray, causing the panel to become dirty; it can also effectively prevent the residual glue after switching foams for different models from affecting the normal use of the tray.

[0041] In an optional embodiment, a PCB component avoidance area 5 is provided along the length of the product loading area. The PCB component avoidance area 5 is convex-shaped, with both its shorter and longer sides extending along the width of the tray body (i.e., the length of the product loading surface), with the shorter side being closer to the center of the product loading area than the longer side. The first pre-set recesses are symmetrically arranged at least along the width of the product loading surface, and second pre-set recesses are symmetrically provided on either side of the protruding portion of the convex-shaped PCB component avoidance area.

[0042] In an optional embodiment, the sub-preset recesses 31 have the same depth, with the depth error between different sub-preset recesses 31 not exceeding ±0.2 mm. The sub-preset recesses 31 have the same size, with the size error between different sub-preset recesses 31 not exceeding ±0.2 mm. The same size means that the length-to-width ratio of different sub-preset recesses 31 is the same.

[0043] The interconnected rectangular limit trough design corresponding to different sizes of machines is conducive to the ABS turnover tray vacuum forming, preventing the gap between the troughs from being too small, which would cause the vacuum forming process to fail; it also provides working space for removing excess foam when switching between machine models.

[0044] In an alternative embodiment, Figure 3 As shown, the limiting foam 4 is an EVA foam 41 with a foaming rate of 10 times, which is fixed in the sub-preset groove 31 by a high-temperature resistant adhesive 42. Specifically, the specifications of the EVA foam can be selected as 20*9*9mm (length*width*height), and the allowable errors of length, width and height are not more than 0.2mm each, and the product limit height is 7mm. The adhesive is selected to be resistant to high temperatures of 90°C and meet the requirements of the baking process, and the thickness of the adhesive is not more than 0.15mm. In a preferred embodiment, the tray body is made of ABS material with a thickness of 1.0 to 2.0mm. In an optional embodiment, a tray inner groove limit 6 is provided around the product bearing surface, and the preset groove 3 is provided in the area formed by the tray inner groove limit 6.

[0045] In a specific embodiment, the tray body 1 is further provided with suction cups 10 , which are arranged at the four corners of the product carrying surface 2 for adsorbing products.

[0046] In an optional embodiment, the position of the sub-preset sink 31 is set according to the product size and the number of common models. Figure 1 and Figure 4 As shown in FIG, in this specific embodiment, five types of machines can be shared, and the sub-preset sinks 31 are arranged in a V-shape, and adjacent sub-preset sinks 31 are connected to each other.

[0047] Among them, such as Figure 4 As shown, the groove with the text 14-2 is the limit groove corresponding to the first model; the groove with the text 14-1 is the limit groove corresponding to the second model; the groove with the text 13.3 is the limit groove corresponding to the third model; the groove with the text 15.6 is the limit groove corresponding to the fourth model, and its side is the tray inner groove limit 6; the tray inner groove limit 6 corresponds to the fifth model.

[0048] Specifically, the first model may be a 14-inch 16:10 model, the second model may be a 13.3-inch model, the third model may be a 14-inch 16:9 model, the fourth model may be a 15.6-inch model, and the fifth model may be a 16-inch model.

[0049] In all models, the non-terminal side is limited by the non-terminal side tray inner groove limiter 61.

[0050] like Figure 2 As shown, in an optional embodiment, a plurality of grooves 8 are provided at intervals on the frame 7, and protrusions 9 are provided on the side walls of the grooves 8 for limiting positioning and ensuring the gaps between stacked trays.

[0051] like Figure 2 As shown, a groove 8 extending along the length of the tray body 1 is connected to the adjacent frame 7 to provide ventilation and act as a handle. For example, ventilation is required during the gluing process during product operation, and it can also serve as a handle during manual operation. The opening of the frame 7 is smaller than the opening of the groove 8.

[0052] Reference again Figure 2 In an optional embodiment, a T-shaped boss 11 is provided on the frame 7. The T-shaped boss 11 does not overlap with the groove 8 on the frame in the width direction. A rectangular boss 12 is provided on at least one side of the T-shaped boss 11. The T-shaped boss 11 and the rectangular boss 12 are used to limit the position and ensure the stacking gap between stacked trays.

[0053] In a specific embodiment, the number of rectangular bosses 12 on both sides of at least one T-shaped boss 11 in a multi-size common turnover pallet is less than the number of rectangular bosses 12 on both sides of other T-shaped bosses 11. Figure 1 As shown in Figure 1 The embodiment in FIG shows four T-shaped bosses, wherein the number of the T-shaped boss 11 with one rectangular boss 12 provided on one side is one, and the number of the T-shaped bosses with rectangular bosses 12 provided on both sides is three.
