Description

Technical Field

[0001] This invention relates to the field of optical component packaging technology, and in particular to a packaging box. Background Technology

[0002] Optical components are typically packaged in waffle boxes, which offer excellent protection and convenience, and meet the needs of automated assembly production.

[0003] In existing technologies, wok boxes are typically manufactured using injection molding, and to facilitate demolding, the inner wall of the box cavity is not perfectly perpendicular to the bottom (e.g., Figure 14 As shown in the figure, the optical components are not upright in the slot, but at a certain angle. For optical components with a smaller height, they can stand upright in the slot because their center of gravity is relatively low. However, for optical components with a larger height, they are difficult to keep upright in the slot because their center of gravity is relatively high. This causes the optical components to tilt in the slot, and the tilted optical components make it difficult for the picker to pick them up during the automated placement process. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of the present invention is to provide a packaging box to solve the problem of difficulty in picking up tall optical component packaging boxes during automated mounting in the prior art.

[0005] The packaging box provided in this embodiment of the invention includes:

[0006] A tray with several placement slots formed on its top surface for placing optical components, the placement slots being gradually narrowed in its depth direction;

[0007] A limiting member is installed on the top surface of the tray. The limiting member has a plurality of limiting holes on the side facing away from the tray. The positions of the plurality of limiting holes correspond one-to-one with the positions of the plurality of placement slots and are connected to the corresponding placement slots. The limiting holes are used to limit the optical element to the side away from the bottom of the placement slot.

[0008] In one embodiment, the limiting hole has a gradually narrowing tendency in the direction of the limiting member toward the tray.

[0009] In one embodiment, the tray is provided with a card slot, a plurality of placement slots are disposed at the bottom of the card slot, and the limiting member is embedded in the card slot.

[0010] In one embodiment, the depth of the slot is greater than the thickness of the limiting member, so that the portion of the optical element protruding from the limiting member can be located in the slot.

[0011] In one embodiment, the limiting member is made of an antistatic material; and / or, the tray is made of an antistatic material.

[0012] In one embodiment, a lid is also included, which is disposed on the side of the limiting member facing away from the tray, and the lid is used to cover a plurality of the limiting holes.

[0013] In one embodiment, the tray is provided with a first protrusion, the limiting member is installed on the first protrusion, and the box cover is provided with a receiving groove on the side facing the tray. The shape of the receiving groove is adapted to the outer contour shape of the first protrusion, and the first protrusion is accommodated in the receiving groove.

[0014] In one embodiment, a latching member is further included. The latching member includes a base plate and two hooks. The two hooks are connected to the base plate and located on both sides of the base plate. The hooks include clamping plates. In the thickness direction of the base plate, the clamping plates are spaced apart from the base plate so that the box cover and the tray can be clamped between the clamping plates and the base plate.

[0015] In one embodiment, the lid has a second protrusion, which is disposed opposite to the receiving groove in the thickness direction of the lid.

[0016] In one embodiment, the substrate includes a main body and two elastic abutments, the two elastic abutments being respectively connected to the other two sides of the main body, the elastic abutments being used to support the tray so that the box lid abuts against the clamp.

[0017] Compared with the prior art, the beneficial effects of the packaging box provided in the embodiments of the present invention are as follows:

[0018] The packaging box of this application can not only store optical components, but also limit the position of each optical component during the automated placement process so that the picker can perform the picking operation.

[0019] Specifically, a limiting component is installed on the top of the tray, with several limiting holes that correspond one-to-one with the positions of the placement slots and communicate with them. When an optical component is placed in a slot, each limiting hole limits the side of the optical component away from the bottom of the slot, ensuring that each optical component remains in a preset relative position, i.e., in a relatively upright state. This allows the operator to easily and quickly pick up each optical component, ensuring easy access during automated placement and improving the accuracy and efficiency of component handling.

[0041] 2000, Optical Components Detailed Implementation

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0043] This invention provides a packaging box 1000 for packaging optical components 2000. For example... Figure 1 - Figure 5 As shown, the packaging box 1000 includes a tray 10 and a limiting member 20. The top surface of the tray 10 has several placement slots 11 for placing optical components 2000. The placement slots 11 gradually narrow in their depth direction. The limiting member 20 is installed on the top surface of the tray 10. A plurality of limiting holes 21 are provided on the side of the limiting member 20 facing away from the tray 10. The positions of the limiting holes 21 correspond one-to-one with the positions of the placement slots 11 and are connected to the corresponding placement slots 11. The limiting holes 21 are used to limit the side of the optical component 2000 away from the bottom of the placement slot 11. This application solves the problem in the prior art where the optical component 2000 is difficult to pick up during automated production due to its own structural problems in waffle boxes. The packaging box 1000 of this application can not only store multiple optical components 2000 at once, providing protection for the optical components 2000 and facilitating their transfer and handling, but also ensures that each optical component 2000 is in a suitable relative position, so as to facilitate the picking operation of the material handler during automated placement.

[0044] Specifically, to facilitate demolding, each placement slot 11 formed by the tray 10 is gradually narrowed in its depth direction, meaning the slot wall and bottom of the placement slot 11 are at a certain angle. When several optical elements 2000 are stored in the multiple placement slots 11 of the tray 10, the optical elements 2000 cannot maintain a relatively upright state within the placement slots 11. In this application, a limiting member 20 is installed on the top of the tray 10, and the limiting member 20 has several limiting holes 21 that correspond one-to-one with the positions of the placement slots 11 and are connected to the corresponding placement slots 11. When an optical element 2000 is placed in a placement slot 11, each limiting hole 21 limits the side of the optical element 2000 away from the bottom of the placement slot 11, ensuring that each optical element 2000 can maintain a preset relative position, that is, the optical element 2000 is in a relatively upright state. In this way, each optical element 2000 can be easily and quickly picked up by the picker, ensuring that each optical element 2000 is easy to use during the automated placement process, thus improving the accuracy and efficiency of picking.

[0045] It is worth mentioning that in the prior art, when storing optical components 2000 with a relatively large height, the depth of the waffle box cavity needs to be set deeper. However, with the increase in cavity depth, in order to smoothly remove the mold during the injection molding process, the inclination of the cavity wall becomes more obvious. Moreover, for optical components 2000 with a relatively 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 cavity. The packaging box 1000 of this application can solve this problem, and it can meet the transportation and production needs of such optical components 2000 with a large height, with good adaptability.

[0046] It should be noted that the optical element 2000 is in a relatively upright state, which can mean that the optical element 2000 is perpendicular to the bottom of the placement groove 11. It is understood that the relatively upright state of the optical element 2000 can also reduce the tilt angle between the optical element 2000 and the bottom of the placement groove 11, keeping the optical element 2000 in a preset position to facilitate material handling by the robotic arm. This preset position can be freely adjusted according to the robotic arm in automated production and is not limited here. For example, in this application, the limiting member 20 can limit the angle formed by the line connecting the optical element 2000 and the line connecting them in the depth direction of the placement groove 11 (e.g., ...). Figure 7 The angle θ (as shown in the figure) is controlled between 0° and 3° to facilitate the picking robot to pick up the optical element 2000. For example, it satisfies the requirement that the upper suction nozzle of the picking robot stably adsorbs the optical element 2000.

[0047] The shape of the tray 10 can be adjusted as needed and is not limited herein. For example, in this application, the tray 10 is square, which is convenient to handle and facilitates the stacking and transportation of multiple packaging boxes 1000.

[0048] The arrangement of the plurality of placement slots 11 on 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 circular, the plurality of placement slots 11 can be arranged in a circular array around the circumference of the tray 10.

[0049] Reference Figure 5 In one embodiment, the limiting hole 21 gradually narrows in the direction of the limiting member 20 toward 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, it can ensure that the limiting hole 21 limits the optical element 2000 and prevent the optical element 2000 from being misaligned; 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 place into the limiting hole 21, and the optical element 2000 can also slide smoothly down the hole wall of the limiting hole 21 to the bottom of the placement slot 11 under its own gravity. The storage process does not require precise alignment by the operator, which improves the convenience of storage.

[0050] There are many ways in which the limiting member 20 is installed on the tray 10. For example, it can be glued, snap-fitted, or integrally molded, and no limitation is made here.

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

[0052] It is worth mentioning that by implementing the above embodiments, the limiting component 20 and the tray 10 are manufactured separately and connected by embedding, which can reduce the manufacturing difficulty of the limiting component 20 and the tray 10, effectively reduce the mold opening cost, and is 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 the overall structural strength, thereby improving the stability and reliability of the packaging box 1000.

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

[0055] Similarly, in one embodiment, the tray 10 is provided with a second process groove 14. Its effect is consistent with the above embodiment, and will not be repeated here.

[0056] Reference Figure 7 In one embodiment, the depth of the slot 12 (e.g. Figure 7 (As shown in H5) is greater than the thickness of the limiting member 20 (e.g.) Figure 7 As shown in H3, the optical element 20000 protruding from the limiting member 21 is positioned within the slot 12. With this arrangement, one side of the optical element 2000 is located in the placement slot 11, while the other side protrudes from the limiting hole 21 and remains within the slot 12. Because the optical element 2000 is within the slot 12, the slot 12 reduces the probability of the optical element 2000 being struck by external components, thus improving the protection of the optical element 2000. Specifically, the sum of the depth of the slot 12 and the depth of the placement slot 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 slot 11 is less than the height of the optical element 2000.

[0057] The thickness of the limiting member 20 and the depths 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 this application, the height of the optical element 2000 is 4.1 mm, the thickness of the limiting member 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 is 2000 (e.g. Figure 7 (as shown in H1), and the thickness of the limiting member 20 (as shown in H1). Figure 7 (as shown in H3) and the depth of the placement groove 11 (as shown in H3) Figure 7 The height difference between the sum of the height of the optical element 2000 and the thickness of the limiting member 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 between the sum of the height of the optical element 2000 and the thickness of the limiting member 20 and the depth of the placement groove 11 is 0.2 mm.

[0059] The depth of slot 12 (e.g.) Figure 7 (as shown in H5) and the depth of the placement groove 11 (as shown in H5) Figure 7 shown in H4) and (such as Figure 7 (as shown in H2) and the optical element 2000 height (as shown in H2) Figure 7The height difference (as shown in H1) 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, while satisfying the need to limit the optical element 2000, the size of the packaging box 1000 can be effectively reduced, minimizing the occupation of external space, making the packaging box 1000 more compact, and facilitating storage, transfer, and transportation.

[0060] In one embodiment, the limiting member 20 is made of an anti-static material; and / or, the tray 10 is made of an anti-static material. This arrangement effectively reduces the accumulation and release of static electricity by using anti-static materials for the limiting member 20 and the tray 10, thereby reducing the impact of static electricity on the optical element 2000 and protecting the safety of the optical element 2000.

[0061] Reference Figure 1 and Figure 2 In one embodiment, the packaging box 1000 further includes a lid 30, which covers the side of the limiting member 20 facing away from the tray 10. The lid 30 is used to cover a plurality of limiting holes 21. With this arrangement, the lid 30 can further improve the protection of the optical element 2000, and on the other hand, the lid 30 can limit the optical element 2000 to prevent it from falling out of 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 protrusion 13, and a limiting member 20 is installed on the first protrusion 13. The lid 30 has a receiving groove 31 on the side facing the tray 10. The shape of the receiving groove 31 matches the outer contour of the first protrusion 13, and the first protrusion 13 is accommodated in the receiving groove 31. This arrangement, with the receiving groove 31 and the first protrusion 13 engaging, increases the contact area between the lid 30 and the tray 10, improving the stability of the connection. Furthermore, the first protrusion 13 positions the receiving groove 31, allowing the operator to more quickly fasten the lid 30 onto the tray 10, improving assembly efficiency. Specifically, the outer contour of the first protrusion 13 matches the groove wall of the receiving groove 31.

[0063] Refer again Figure 8In one embodiment, the tray 10 includes a first outer peripheral surface surrounding its top surface, with a first chamfer 15 at the first outer peripheral surface. The lid 30 includes a second outer peripheral surface surrounding the first outer peripheral surface, with a second chamfer 33 at the second outer peripheral surface. When the lid 30 is placed on the tray 10, the first chamfer 15 and the second chamfer 33 are positioned opposite each other. Thus, the cooperation of the first chamfer 15 and the second chamfer 33 serves to prevent accidental operation, avoiding misoperation when the lid is closed. The operator can determine whether the lid 30 is correctly closed onto the tray 10 by observing the relative positions of the first chamfer 15 and the second chamfer 33, improving the accuracy of the operation.

[0064] Reference Figure 1 and Figure 9 In one embodiment, the packaging box 1000 further includes a latching member 40, which includes a base plate 41 and two hooks 42. The two hooks 42 are connected to the base plate 41 and located on both sides of the base plate 41. The hooks 42 include clamping plates 421. The clamping plates 421 are 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 plates 421 and the base plate 41. With this arrangement, the box cover 30 and the tray 10 can be clamped between the clamping plates 421 and the base plate 41, which can restrict the movement of the box cover 30. The latching member 40 can prevent the box cover 30 from detaching from the tray 10, ensuring that the optical components 2000 will not fall out of the packaging box 1000 during the transfer and transportation process.

[0065] In one embodiment, the fastener 40 is made of plastic. For example, the fastener 40 can be made of PP material. Thus, the PP material fastener 40 has good tensile and fatigue resistance, can withstand long-term use without damage, and has better durability.

[0066] Reference Figure 10 In one embodiment, the lid 30 is provided with a second protrusion 32, which is disposed opposite to the receiving groove 31 in the thickness direction of the lid 30. Thus, the structural strength of the receiving groove 31 area of ​​the lid 30 is reduced, while the second protrusion 32 can increase the overall structural strength of the lid 30, making the lid 30 less prone to deformation and damage.

[0067] Specifically, the second protrusion 32 is located between the two clamping plates 421 to limit the lid 30. With this arrangement, the two clamping plates 421 can guide and limit the second protrusion 32, so that the lid 30 can be in the correct position preset by the fastener 40, making assembly more convenient and efficient.

[0068] Reference Figure 9 - Figure 11In one embodiment, the substrate 41 includes a main body 411 and two elastic abutment members 412. Two hooks 42 are respectively connected to both sides of the main body 411, and the two elastic abutment members 412 are respectively connected to the other two sides of the main body 411. The elastic abutment members 412 are used to support the tray 10 so that the lid 30 abuts against the clamping plate 421. The elastic abutment members 412 can elastically deform. The bottom of the tray 10 abuts against the elastic abutment members 412. When the elastic abutment members 412 are compressed, the tray 10 and the lid 30 can be smoothly placed between the clamping plate 421 and the substrate 41. Then the elastic abutment members 412 return to their original shape and move the tray 10 towards the clamping plate 421 through their own elastic force, thereby making the lid 30 securely abut against the clamping plate 421, ensuring that the lid 30 and the tray 10 are securely connected and preventing the lid 30 from separating from the tray 10 during transportation and transfer.

[0069] Specifically, one end of the elastic support 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 support member 412 is located between the clamping plate 421 and the substrate 41.

[0070] Reference Figure 12 and Figure 13 In one embodiment, the elastic support member 412 is provided with a limiting block 4121 on the side facing the bottom of the tray 10. The limiting block 4121 abuts against the bottom of the tray 10 to restrict the movement of the tray 10 in the horizontal direction and prevent the lid 30 from disengaging from the tray 10 from the fastener 40.

[0071] Specifically, the bottom of the tray 10 is provided with a limiting groove 16, 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 lid 30 and the tray 10 maintain a relative position.

[0072] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of the present invention.
