[0041] 2000、Optical Components DETAILED DESCRIPTION

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention are described in detail.

[0043] The embodiment of the present invention provides a packaging box 1000, which is used for packaging an optical element 2000. Figure 1 - Figure 5 As shown, the packaging box 1000 includes a tray 10 and a stopper 20. The top surface of the tray 10 is formed with a plurality of placement grooves 11, which are used to place the optical element 2000. The placement grooves 11 are gradually narrowed in the depth direction. The stopper 20 is installed at the top surface of the tray 10. The side of the stopper 20 facing away from the tray 10 is provided with a plurality of stopper holes 21. The plurality of stopper holes 21 correspond to the positions of the plurality of placement grooves 11 one by one, and are connected to the corresponding placement grooves 11. The stopper holes 21 are used to stop the optical element 2000 from being away from the side of the bottom of the placement groove 11. The present application can solve the problem that the optical element 2000 is difficult to pick up in the automated production process due to the structural problems of the waffle box in the prior art. The packaging box 1000 of the present application can not only store multiple optical elements 2000 at one time, provide protection for the optical elements 2000, and facilitate their transfer and handling, but also ensure that each optical element 2000 is in a suitable relative position, so that it is convenient for the material picker to perform the picking operation in the automated patch process.

[0044] Specifically, in order to facilitate demolding, each placement groove 11 formed on the tray 10 is gradually narrowed in its depth direction, that is, the groove wall of the placement groove 11 is inclined at a certain angle to its groove bottom. When a plurality of optical elements 2000 are respectively stored in a plurality of placement grooves 11 of the tray 10, the optical elements 2000 cannot maintain a relatively upright state in the placement grooves 11. In the present application, since a limiting member 20 is installed on the top of the tray 10, the limiting member 20 is provided with a plurality of limiting holes 21 corresponding to the positions of the placement grooves 11 and connected to the corresponding placement grooves 11. When the optical element 2000 is placed in the placement groove 11, each limiting hole 21 will limit the side of the optical element 2000 away from the bottom of the placement groove 11, ensuring that each optical element 2000 can be maintained in a preset relative position, that is, the optical element 2000 is in a relatively upright state. In this way, each optical component 2000 can be easily picked up by the picker accurately and quickly, and in the automated placement process, each optical component 2000 is ensured to be easy to access, thereby improving the accuracy and efficiency of picking.

[0045] It is worth mentioning that in the prior art, when storing optical components 2000 with a large height, the depth of the groove of the waffle box needs to be set deeper. As the depth of the groove increases, in order to smoothly pull out the mold during the injection molding process, the inclination of the groove wall of the groove becomes more obvious. For optical components 2000 with a large height, due to their high center of gravity, it is ultimately difficult for the entire optical component 2000 to remain relatively upright in the groove. The packaging box 1000 of the present application can solve this problem, and it can meet the transportation and production of such optical components 2000 with a large height, and has good adaptability.

[0046] It should be noted that the optical element 2000 is in a relatively upright state, which means that the optical element 2000 is perpendicular to the bottom of the placement groove 11. It can be understood that the optical element 2000 is in a relatively upright state, which can reduce the inclination angle between the optical element 2000 and the bottom of the placement groove 11, so that the optical element 2000 is kept at a preset position to facilitate the material picking by the material picking robot. The preset position can be freely adjusted according to the material picking robot in automated production, and is not limited here. For example, in the present application, the limit member 20 can limit the angle formed by the optical element 2000 and the line connecting the depth direction of the placement groove 11 (such as Figure 7 θ (as shown in FIG. 1 ) is controlled within a range of 0° to 3° to facilitate the material picking robot to pick up the optical element 2000, for example, to ensure that the suction nozzle on the material picking robot can stably adsorb the optical element 2000.

[0047] The shape of the tray 10 can be adjusted according to the requirements, and is not limited here. For example, in the present application, the tray 10 is square, which is convenient to take and is conducive to stacking and transporting multiple packaging boxes 1000.

[0048] The arrangement of the plurality of placement slots 11 of the tray 10 can be freely adjusted according to the shape of the tray 10, and is not limited here. For example, when the tray 10 is square, the plurality of placement slots 11 can be arranged in an array along the length and width of the tray 10; for another example, when the tray 10 is round, the plurality of placement slots 11 can be arranged in a circumferential array around the tray 10.

[0049] Reference Figure 5 In one embodiment, the limiting hole 21 has a tendency to gradually narrow in the direction from the limiting member 20 to the tray 10. That is, the entrance of the limiting hole 21 is larger than the exit of the limiting hole 21. In this way, on the one hand, the limiting hole 21 can limit the optical element 2000 and prevent the optical element 2000 from being offset; on the other hand, the limiting hole 21 has a guiding function. When placing the optical element 2000, since the entrance of the limiting hole 21 is larger than the exit of the limiting hole 21, the optical element 2000 is easier to be placed in the limiting hole 21, and the optical element 2000 can also slide smoothly through the hole wall of the limiting hole 21 to the bottom of the placement slot 11 under the action of its own gravity. The storage process does not require the operator to accurately align, which improves the convenience of storage.

[0050] There are many ways to install the limiting member 20 on the tray 10, such as bonding, snap connection or integral molding, which is not limited here.

[0051] Reference Figure 6 For example, in one embodiment, a slot 12 is provided on the tray 10, a plurality of placement slots 11 are provided at the bottom of the slot 12, and the stopper 20 is embedded in the slot 12. In this way, the stopper 20 is embedded in the slot 12, which can ensure the reliability of the connection between the stopper 20 and the tray 10, and the slot 12 can limit the stopper 20, ensuring that each stopper hole 21 can be connected with each placement slot 11, thereby improving the stability of the overall structure.

[0052] It is worth mentioning that, by implementing the above embodiment, the limit member 20 and the tray 10 are manufactured separately and connected by embedding, which can reduce the difficulty of manufacturing the limit member 20 and the tray 10, thereby effectively reducing the mold opening cost and being more suitable for mass production.

[0053] Preferably, the limiting member 20 and the card slot 12 are tightly fitted to further improve the connection stability and make the overall structural strength better, thereby improving the stability and reliability of the packaging box 1000.

[0054] Reference Figure 6In one embodiment, the stopper 20 is formed by injection molding. A first process groove 22 is provided on the stopper 20. Thus, the first process groove 22 can provide a more stable support during the injection molding process of the stopper 20, so that the molten plastic can fill the mold cavity more evenly, reducing the overall deformation or surface unevenness caused by uneven injection molding.

[0055] Similarly, in one embodiment, a second process tank 14 is provided on the tray 10. The effect thereof is consistent with that of the above embodiment, and will not be repeated here.

[0056] Reference Figure 7 In one embodiment, the depth of the slot 12 (eg Figure 7 ) is greater than the thickness of the stopper 20 (as shown in H5 in FIG. Figure 7 ), so that the portion of the optical element 20000 that passes through the limiting member 20 can be located in the card slot 12. In this way, one side of the optical element 2000 is located in the placement groove 11, and the other side passes through the limiting hole 21 and is also located in the card slot 12. Since the optical element 2000 is in the card slot 12, the card slot 12 can reduce the probability of the optical element 2000 being hit by external components, thereby improving the protection of the optical element 2000. Specifically, the sum of the depth of the card slot 12 and the depth of the placement groove 11 is greater than the height of the optical element 2000, and the sum of the thickness of the limiting member 20 and the depth of the placement groove 11 is less than the height of the optical element 2000.

[0057] The thickness of the stopper 20, the depth of the slot 12 and the placement slot 11 can be freely adjusted according to the height of the optical element 2000, and are not limited here. For example, in the present application, the height of the optical element 2000 is 4.1 mm, the thickness of the stopper 20 is 1.2 mm, the depth of the placement slot 11 is 2.7 mm, and the depth of the slot 12 is 1.5 mm.

[0058] Preferably, the height of the optical element 2000 (eg Figure 7 ), and the thickness of the stopper 20 (as shown in H1 in FIG. Figure 7 H3 in FIG. 1 ) and the depth of the placement groove 11 (as shown in FIG. Figure 7 The height difference of the sum of the height of the optical element 2000 and the thickness of the stopper 20 and the depth of the placement groove 11 is greater than or equal to 0.1 mm and less than or equal to 0.3 mm. For example, the height difference of the sum of the height of the optical element 2000 and the thickness of the stopper 20 and the depth of the placement groove 11 is 0.2 mm.

[0059] The depth of the slot 12 (eg Figure 7 H5 in FIG. 1 ) and the depth of the placement groove 11 (as shown in FIG. Figure 7 shown in H4) and (such as Figure 7 ) and the height of the optical element 2000 (as shown in H2 in Figure 7The height difference between the depth of the card slot 12 and the placement slot 11 and the height of the optical element 2000 is greater than or equal to 0.05 mm and less than or equal to 0.15 mm. For example, the height difference between the sum of the depths of the card slot 12 and the placement slot 11 and the height of the optical element 2000 is 0.1 mm. In this way, the size of the packaging box 1000 can be effectively reduced while the optical element 2000 is limited, and the external space occupied can be reduced, making the packaging box 1000 more compact and convenient for storage, transfer and transportation.

[0060] In one embodiment, the stopper 20 is made of antistatic material; and / or, the tray 10 is made of antistatic material. In this way, the stopper 20 and the tray 10 made of antistatic material can effectively reduce the accumulation and release of static electricity, reduce the impact of static electricity on the optical element 2000, and protect the safety of the optical element 2000.

[0061] Reference Figure 1 and Figure 2 In one embodiment, the packaging box 1000 further includes a box cover 30, which is disposed on the side of the limiting member 20 facing away from the tray 10, and is used to cover the plurality of limiting holes 21. With such a configuration, the box cover 30 can further improve the protection of the optical element 2000 on the one hand, and on the other hand, the box cover 30 can limit the optical element 2000 to prevent the optical element 2000 from being separated from the placement slot 11, which is beneficial for transportation and transfer.

[0062] Reference Figure 8 In one embodiment, the tray 10 is provided with a first boss 13, the stopper 20 is installed at the first boss 13, and the side of the box cover 30 facing the tray 10 is provided with a receiving groove 31, the shape of the receiving groove 31 is adapted to the outer contour of the first boss 13, and the first boss 13 is accommodated in the receiving groove 31. In this way, the receiving groove 31 cooperates with the first boss 13, which can increase the contact area between the box cover 30 and the tray 10 and improve the stability of the connection. In addition, the first boss 13 positions the receiving groove 31, so that the operator can snap the box cover 30 onto the tray 10 more quickly, thereby improving the assembly efficiency. Specifically, the outer contour of the first boss 13 is adapted to the groove wall of the receiving groove 31.

[0063] Refer again Figure 8In one embodiment, the tray 10 includes a first peripheral surface arranged around the top surface, and a first chamfer 15 is arranged at the first peripheral surface. The box cover 30 includes a second peripheral surface arranged around the first peripheral surface, and a second chamfer 33 is arranged at the second peripheral surface. When the box cover 30 is placed on the tray 10, the positions of the first chamfer 15 and the second chamfer 33 correspond. In this way, the first chamfer 15 cooperates with the second chamfer 33 to play a foolproof role, avoiding the operator from making a mistake when fastening the cover. The operator can judge whether the box cover 30 is correctly fastened on the tray 10 by the relative position of the first chamfer 15 and the second chamfer 33, thereby improving the correctness of the operation.

[0064] Reference Figure 1 and Fig. 9 In one embodiment, the packaging box 1000 further includes a fastener 40, which includes a base plate 41 and two hooks 42, the two hooks 42 are connected to the base plate 41 and are located on both sides of the base plate 41, and the hooks 42 include a clamping plate 421, and the clamping plate 421 is spaced apart from the base plate 41 in the thickness direction of the base plate 41, so that the box cover 30 and the tray 10 can be clamped between the clamping plate 421 and the base plate 41. In this way, the box cover 30 and the tray 10 can be clamped between the clamping plate 421 and the base plate 41 by the clamping plate 421, which can limit the movement of the box cover 30, and the setting of the fastener 40 can prevent the box cover 30 from being separated from the tray 10, ensuring that the optical element 2000 will not be scattered from the inside of the packaging box 1000 to the outside during the transfer and transportation process.

[0065] In one embodiment, the buckle 40 is made of plastic material. For example, the buckle 40 can be made of PP material. In this way, the buckle 40 made of PP material has good tensile and fatigue resistance, can withstand long-term use without being easily damaged, and has better durability.

[0066] Reference Fig.10 In one embodiment, the box cover 30 is provided with a second boss 32, and in the thickness direction of the box cover 30, the second boss 32 and the receiving groove 31 are arranged opposite to each other. In this way, the box cover 30 is provided with the receiving groove 31, and the structural strength in the area of ​​the receiving groove 31 is reduced. The provision of the second boss 32 can increase the overall structural strength of the box cover 30, making the box cover 30 less likely to be deformed and damaged.

[0067] Specifically, the second boss 32 is located between the two clamping plates 421 to limit the box cover 30. In this way, the two clamping plates 421 can guide and limit the second boss 32, so that the box cover 30 can be in the correct position preset by the buckle 40, making assembly more convenient and efficient.

[0068] Reference Fig. 9 - Fig.11In one embodiment, the base plate 41 includes a main body 411 and two elastic abutting members 412. The two hooks 42 are respectively connected to two sides of the main body 411, and the two elastic abutting members 412 are respectively connected to the other two sides of the main body 411. The elastic abutting members 412 are used to support the tray 10 so that the box cover 30 abuts against the clamping plate 421. The elastic abutting members 412 can be elastically deformed, and the bottom of the tray 10 abuts against the elastic abutting members 412. The elastic abutting members 412 are compressed, so that the tray 10 and the box cover 30 can be smoothly placed between the clamping plate 421 and the base plate 41. Then the elastic abutting members 412 return to their original state, and the tray 10 moves toward the clamping plate 421 through its own elastic force, so that the box cover 30 is firmly abutted against the clamping plate 421, ensuring that the box cover 30 is firmly connected to the tray 10, and avoiding the box cover 30 and the tray 10 from being separated during transportation and transfer.

[0069] Specifically, one end of the elastic supporting member 412 is connected to the main body 411 , and the other end extends toward the clamping plate 421 and is bent. The other end of the elastic supporting member 412 is located between the clamping plate 421 and the base plate 41 .

[0070] Reference Fig.12 and Fig.13 In one embodiment, a limit block 4121 is provided on one side of the elastic supporting member 412 toward the bottom of the tray 10 , and the limit block 4121 abuts against the bottom of the tray 10 to limit the movement of the tray 10 in the horizontal plane direction and prevent the box cover 30 and the tray 10 from being separated from the latch 40 .

[0071] Specifically, a limiting groove 16 is provided at the bottom of the tray 10 , and the limiting block 4121 is accommodated in the limiting groove 16 . The limiting groove 16 can limit the movement of the limiting block 4121 , so that the box cover 30 and the tray 10 maintain a relative position.
