Description

Technical Field

[0001] The present disclosure relates to carriers and applications thereof, and in particular to carrier trays and carrier tray stacking assemblies. Background Art

[0002] The carrier tray is mainly used to carry electronic items such as backlight modules or screens, and the carrier trays can be stacked on each other to save space and facilitate transportation.

[0003] Generally speaking, electronic items are covered with a protective film. When the electronic items are installed in the carrier tray, the protective film is usually pressed by the carrier surface of the upper carrier tray. However, this method has a small clamping area, so the vertical pressing force is also low, so the protective film cannot be effectively fixed, resulting in poor overall packaging reliability. On the other hand, the conventional carrier tray design mainly uses the upper and lower adjacent carrier trays to flip 180 degrees based on the vertical axis to stack to form a space for accommodating electronic items. This method requires more assembly time and cost. Summary of the invention

[0004] Therefore, the purpose of the embodiments of the present disclosure is to provide a carrier tray, which has the function of clamping and pressing the protective film of the carrier, and can improve the stability of the overall packaging and the assembly or packaging efficiency of the production line.

[0027] Please refer to Figure 1 , Figure 1 FIG. 2 is a schematic diagram showing the structure of a carrier tray stacking assembly according to an embodiment of the present disclosure. The present embodiment mainly provides a carrier tray 200, which is mainly used to carry objects (e.g. Figure 4 The carrier B1 shown in the figure) and the carrier plates 200 can be stacked together to form a carrier plate stacking assembly 100. In this embodiment, in addition to the functions of carrying and being stackable, the carrier plates 200 also have the functions of clamping and limiting the protective film B2 coated on the outside of the carrier B1 (such as Figure 4 shown).

[0028] Please also refer to Figures 2A to 4,in Figure 2A is a schematic cross-sectional view of a carrier plate according to an embodiment of the present disclosure. Figure 2B It is shown Figure 2A An enlarged schematic diagram of part A of Figure 3 It is drawn along Figure 1 The cross-section diagram cut by the AA section line, Figure 4 It is a schematic diagram illustrating the structural use status of a carrier tray according to an embodiment of the present disclosure. The carrier tray 200 of this embodiment includes a carrier portion 210, a surrounding wall portion 220 and at least one recessed structure 230. Among them, the surrounding wall portion 220 is arranged in a ring around the carrier portion 210. In one embodiment, a plurality of alignment portions 222 may be arranged on the surrounding wall portion 220 to ensure the structural strength of the surrounding wall portion 220. In another embodiment, a plurality of alignment portions 222 may be symmetrically arranged on the surrounding wall portions 220 on opposite sides. Therefore, when the operator packs up the empty carrier tray, there is no need to worry about the direction of the anti-foolproof alignment, thereby improving the assembly or packaging efficiency of the production line. The recessed structure 230 is recessed in the carrier portion 210, such as Figure 3 and Figure 4 As shown, when two carriers 200 are stacked on each other, the carrying portion 210 of the upper carrier 200 and the carrying portion 210 of the lower adjacent carrier 200 jointly form a carrying space A1, and the recessed structure 230 of the upper carrier 200 overlaps with the recessed structure 230 of the lower carrier 200. In this way, the carrier B1 can be arranged on the carrying portion 210 of the lower carrier 200 and located in the carrying space A1, and the protective film B2 coated on the outside of the carrier B1 can be limited by being pressed by the recessed structure 230 of the upper carrier 200.

[0029] like Figure 2A and Figure 2BAs shown, the supporting portion 210 has a top surface 211 and a bottom surface 212 opposite to the top surface 211. The recessed structure 230 has a recessed space 230a and an opening 230b, wherein the recessed space 230a is connected to the outside through the opening 230b. Specifically, the recessed structure 230 has an inner wall 231, an outer wall 232 and a bottom 233, wherein the inner wall 231, the outer wall 232 and the bottom 233 together define the recessed space 230a. In addition, the outer wall 232 is closer to the surrounding wall 220 than the inner wall 231, and the inner wall 231 and the outer wall 232 extend from the supporting portion 210 in a direction away from the bottom surface 212, and the bottom 233 is connected between the inner wall 231 and the outer wall 232. In this embodiment, the recessed space 230a has a first distance D1 along the direction C1, and the opening 230b has a second distance D2 along the direction C1, wherein the first distance D1 is greater than the second distance D2. In one embodiment, a limiting structure 234 is disposed on the bottom surface of the recessed structure 230 of the carrier plate 200, and the limiting structure 234 is a protruding structure extending away from the carrier portion 210. Figure 3 and Figure 4 As shown, the bottom 233 of the recessed structure 230 of the upper carrier plate 200 can completely cover the opening 230b of the recessed structure 230 of the adjacent carrier plate 200 below, and is attached to and carried on the carrying portion 210 of the lower carrier plate 200, so the limiting structure 234 of the upper carrier plate 200 can extend into the recessed space 230a of the lower carrier plate 200, thereby pressing the protective film B2 wrapped around the outside of the carrier B1 into the recessed space 230a. Since the recessed structure 230 of the upper carrier plate 200 is attached downward to the carrying portion 210 of the lower carrier plate 200 due to the vertical pressure, the protective film B2 can be firmly clamped to achieve the purpose of limiting the protective film B2.

[0030] Furthermore, the convex surface of the limiting structure 234 can contact the protective film B2 and increase the friction between the limiting structure 234 and the protective film B2, especially the friction in the horizontal direction, so as to further enhance the fixing effect of the protective film B2.

[0031] Please also refer to Figures 2A to 5 ,in Figure 52 is a partial cross-sectional view of a carrier plate stacking assembly according to an embodiment of the present disclosure. In one embodiment, the inner wall 231 has a first plate portion 231a, a connecting portion 231b and a second plate portion 231c, wherein the connecting portion 231b connects the first plate portion 231a and the second plate portion 231c. The first plate portion 231a of the inner wall 231 is connected to the bottom 233. One end of the connecting portion 231b is connected to the first plate portion 231a, and the other end extends toward the recessed space 230a. The second plate portion 231c of the inner wall 231 extends from the carrier portion 210 and is connected to the other end of the connecting portion 231b. It can be seen that the inner wall 231 is generally designed in an S-shaped stepped structure, and the connecting portion 231b, the second plate portion 231c of the inner wall 231 and the bottom surface 212 of the carrier portion 210 together form a first support space S1. Similarly, the outer wall 232 has a first plate portion 232a, a connecting portion 232b and a second plate portion 232c, wherein the connecting portion 232b connects the first plate portion 232a and the second plate portion 232c. The first plate portion 232a of the outer wall 232 is connected to the bottom 233. One end of the connecting portion 232b is connected to the first plate portion 232a, and the other end extends toward the recessed space 230a. The second plate portion 232c of the outer wall 232 extends from the supporting portion 210 and is connected to the other end of the connecting portion 232b. In other words, the outer wall 232 is generally designed in an S-shaped stepped structure, and the connecting portion 232b, the second plate portion 232c of the outer wall 232 and the bottom surface 212 of the supporting portion 210 together form a second support space S2.

[0032] In this embodiment, the outer wall 232 and the inner wall 231 are symmetrical structures, and the second plate portion 231c of the inner wall 231 and the second plate portion 232c of the outer wall 232 are both connected to the bottom surface 212 of the supporting portion 210. Among them, at least a portion of the recessed space 230a is surrounded by the first plate portion 231a of the inner wall 231 and the first plate portion 232a of the outer wall 232, and the first plate portion 231a of the inner wall 231 and the first plate portion 232a of the outer wall 232 jointly define the aforementioned first distance D1. The opening 230b is surrounded by at least a portion of the second plate portion 231c of the inner wall 231 and at least a portion of the second plate portion 232c of the outer wall 232, and the second plate portion 231c of the inner wall 231 and the second plate portion 232c of the outer wall 232 jointly define the aforementioned second distance D2. Thus, by virtue of the design that the second distance D2 of the opening 230b is smaller than the first distance D1 of the recessed space 230a, the bottom 233 of the recessed structure 230 of the upper carrier plate 200 can be supported on the supporting portion 210 of the lower carrier plate 200, and the portion where the bottom 233 of the upper recessed structure 230 and the supporting portion 210 of the lower carrier plate 200 fit together is located above the first supporting space S1 and the second supporting space S2. It should be noted that the design of the inner wall 231 and the outer wall 232 to be substantially S-shaped stepped structures can not only increase the structural strength and supporting strength of the inner wall 231 and the outer wall 232 themselves, but also utilize the first supporting space S1 and the second supporting space S2 generated by the S-shaped stepped structure to further provide the function of load-bearing buffering and shock absorption.

[0033] Please also refer to Figure 1 , Figure 6 and Figure 7 ,in Figure 6 FIG. 2 is a schematic structural diagram showing another perspective of a carrier tray stacking assembly according to an embodiment of the present disclosure. Figure 7 It is drawn along Figure 1 In one embodiment, the surrounding wall portion 220 is a bending structure erected on the periphery of the supporting portion 210, wherein the bottom of the surrounding wall portion 220 has a bending space 221. Figure 7 As shown, when two carrier plates 200 are stacked on each other, the surrounding wall portion 220 of the upper carrier plate 200 is sleeved outside the surrounding wall portion 220 of the lower adjacent carrier plate 200, thereby preventing the surrounding wall portion 220 of the lower carrier plate 200 from expanding outward due to the weight of the object. Figure 6As shown, when viewed from the bottom of the carrier plate 200, there is an exhaust channel 240 located on the bottom surface of the carrier portion 210 between at least two adjacent recessed structures 230, and the exhaust channel 240 is connected to the bending space 221 surrounding the wall portion 220. The design purpose of the exhaust channel 240 is mainly to allow the air in the bearing space A1 to be discharged to the outside through the exhaust channel 240 via the bending space 221 when multiple carrier plates 200 are stacked on each other, so as to avoid the problem of vacuum adsorption caused by the recessed structure 230 of the upper carrier plate 200 completely closing the bearing space A1 between it and the lower carrier plate 200. In addition, in the present disclosure, since the upper limiting structure 234 extends into the lower recessed space 230a, this can ensure that the upper and lower carrier plates have the function of limiting each other. Compared with the conventional carrier plates, when the upper and lower carrier plates 200 of the present disclosure are stacked, the operator does not need to make a 180-degree flip based on the vertical axis, thereby improving the assembly or packaging efficiency of the production line.

[0034] In the present disclosure, the recessed structure may also have different structural designs. Figure 8 As shown, Figure 8 FIG. 2 is a partial cross-sectional view of another embodiment of a carrier tray stacking assembly according to the present disclosure. The carrier tray stacking assembly 300 of this embodiment is formed by stacking at least two carrier trays 400. The structure of the carrier tray 400 is substantially the same as that of the aforementioned carrier tray 200, except that the recessed structure 430 of the carrier tray 400 has a different shape.

[0035] like Figure 8As shown, the recessed structure 430 has a recessed space 430a and an opening 430b, wherein the recessed space 430a is connected to the outside through the opening 430b. Specifically, the recessed structure 430 has an inner wall 431, an outer wall 432 and a bottom 433, wherein the inner wall 431, the outer wall 432 and the bottom 433 together define the recessed space 430a. In this embodiment, the inner wall 431 is generally designed in an S-shaped stepped structure, the outer wall 432 is a vertical design, and the inner wall 431 includes a first plate portion 431a, a connecting portion 431b and a second plate portion 431c, wherein the first plate 431a is connected to the bottom 433. One end of the connecting portion 431b is connected to the first plate portion 431a, and the other end extends toward the recessed space 430a, and the second plate portion 431c is connected to the other end of the connecting portion 431b. In this embodiment, at least a portion of the recessed space 430a is surrounded by the first plate portion 431a, and at least a portion of the opening 430b is formed by being surrounded by the outer wall 432 and the second plate portion 431c. In this embodiment, the recessed space 430a has a first distance D3 along the direction C2, and the opening 430b has a second distance D4 along the direction C2, wherein the first distance D3 is greater than the second distance D4. Thus, when two carrier trays 400 are stacked on each other, the recessed structure 430 of the upper carrier tray 400 overlaps with the recessed structure 430 of the lower carrier tray 400, thereby achieving the purpose of limiting the protective film of the carrier in the lower carrier tray 400. In other embodiments, a limiting structure 434 is provided at the bottom of the recessed structure 430, so that when two supporting plates 400 are stacked on each other, the limiting structure 434 of the upper supporting plate 400 can extend into the recessed space 430a of the lower supporting plate 400, thereby further pressing the protective film of the supporting component in the lower supporting plate 400 into the recessed space 230a, so as to achieve the purpose of clamping and limiting the protective film.

[0036] It can be known from the above-mentioned embodiments of the present disclosure that the carrier plate of the present disclosure has a recessed structure, and by virtue of the design that the second distance of the opening of the recessed structure is smaller than the first distance of the recessed space, the bottom of the recessed structure of the upper carrier plate can be supported on the supporting portion of the lower carrier plate. Therefore, in addition to providing a support function when the carrier plates are stacked on each other, the recessed structure can also further clamp the protective film of the carrier, so that the clamping area is greatly increased, so that the vertical pressing force can be relatively improved, the fixing effect of the protective film is strengthened, and the assembly or packaging efficiency of the production line is further improved. In addition, the design of the limiting structure can also be matched so that the limiting structure can contact with the protective film to increase the friction between it and the protective film, especially the friction in the horizontal direction, so as to further strengthen the fixing effect of the protective film.

[0037] Although the embodiments of the present disclosure have been disclosed as above, they are not intended to limit the present disclosure. Any technician in the relevant technical field should be able to make some changes and modifications without departing from the spirit and scope of the embodiments of the present disclosure. Therefore, the protection scope of the embodiments of the present disclosure should be based on the scope defined by the attached claims.
