Description

Technical Field

[0001] The present application relates to the technical field of electronic product packaging, and in particular to a packaging assembly. Background Art

[0002] Laser radar products usually include components such as laser emitters, optical elements, receivers, scanning mechanisms, interface circuits, and data processing units. Among them, laser emitters usually use laser diodes or solid-state lasers to generate laser beams by exciting media such as semiconductors or solid crystals. Optical elements include lenses, reflectors and other optical elements, which are used to focus, control the propagation direction of the laser beam and form the required optical system. Receivers usually use photoelectric conversion elements such as photodiodes, photomultiplier tubes or photodetectors to convert the received optical signals into electrical signals. The scanning mechanism can be a rotating mirror, a galvanometer or an electronic scanner, etc., which scans the target area by changing the direction of the laser beam. The interface circuit is responsible for the timing control of laser emission and reception, data transmission and communication interface management. The data processing unit usually includes processing chips, algorithms and software for functions such as extracting target information, distance measurement, and point cloud generation.

[0003] Since the components used in LiDAR products are easy to break when hit or collided, and are relatively small in size. At present, the general packaging method for LiDAR products is to place them directly in the packaging component, or to separate the LiDAR products from the packaging component with a thin gasket. Therefore, when LiDAR products are in direct contact with the packaging component, the components of LiDAR products may be crushed.

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0030] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0031] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0032] In order to solve the technical problem that the parts of laser radar products may be crushed, smashed, etc. when laser radar products are in direct contact with packaging components or during transportation, thereby easily damaging the products. An embodiment of the present application provides a packaging component, including a lower tray and an upper cover, wherein the lower tray includes a receiving groove and a supporting portion, and the supporting portion is used to support the packaged items so that a gap is maintained between the packaged items placed in the receiving groove and the bottom surface of the receiving groove. When the packaged items are placed in the lower tray, the bottom surface of the packaged items can be prevented from directly contacting the bottom surface of the receiving groove, thereby preventing the parts of the packaged items from being crushed by their own gravity, thereby improving the yield of the packaged items. The upper cover is provided with a pressing portion, and in the depth direction of the receiving groove, the pressing portion and the supporting portion are arranged relative to each other to clamp the packaged items, limit the packaged items to the preset position of the packaging component, thereby preventing the packaged items from being damaged due to vibration, collision, etc. during transportation, and further improving the yield of the packaged items. A detailed description will be given below.

[0033] In one embodiment, if Figure 1As shown, a packaging assembly is provided, including an upper cover and a lower tray. The lower tray 100 includes a supporting surface 101, a receiving groove 10 and a supporting portion 13. The receiving groove 10 is recessed in the supporting surface 101 to receive the item 200 to be packaged. The receiving groove includes a bottom surface 10a and a side wall 10b. The supporting portion 13 is located in the receiving groove 10 and convexly disposed on the bottom surface 10a of the receiving groove 10. The supporting portion 13 is used to support the item 200 to be packaged, so that a gap is maintained between the item 200 to be packaged placed in the receiving groove 10 and the bottom surface 10a of the receiving groove 10, so as to avoid direct contact between the bottom surface 10a of the item to be packaged and the bottom surface 10a of the receiving groove, thereby preventing the components of the item to be packaged from being crushed by their own gravity, thereby improving the yield of the item to be packaged.

[0034] like Figures 1 to 3 As shown, the upper cover 300 includes a main body portion 31 and a pressing portion 32. The main body portion 31 covers the supporting surface 101 of the lower tray 100 to close the notch of the accommodating groove 10. The pressing portion 32 is protruded on the side of the main body portion 31 facing the lower tray 100. The pressing portion 32 is arranged opposite to the supporting portion 13 to clamp the packaged item 200 to prevent the components of the packaged item from being crushed by their own gravity, thereby improving the yield of the packaged item.

[0035] like Figure 5 As shown, in the depth direction Z of the accommodating groove 10, the pressing portion 32 and the supporting portion 13 are arranged opposite to each other, and the first part of the to-be-packaged item 200 is clamped by the pressing portion 32 and the supporting portion 13, so as to support and fix the to-be-packaged item 200. The shape of the covering surface of the pressing portion 32 is matched with the shape of the covering surface of the supporting portion 13, so that the first part of the to-be-packaged item 200 can be better clamped.

[0036] The pressing part 32 and the supporting part 13 clamp the first part of the package 200 to limit the package 200 to the preset position of the packaging assembly, thereby effectively ensuring that the package 200 is not damaged when a fault such as vibration or collision occurs. The preset position is the clamping position of the pressing part 32 and the supporting part 13 for the package 200.

[0037] Furthermore, in the depth direction Z of the accommodating groove 10, there are gaps between the main body 31 and the first part of the item to be packaged 200, as well as the second part of the item to be packaged 200. In this way, when the item to be packaged 200 encounters faults such as vibration or collision during transportation, excessive shaking of the item to be packaged 200 that affects its yield is avoided.

[0038] Therefore, the packaging assembly provided in the present application can restrict the item to be packaged 200 to a preset position of the packaging assembly by cooperating with the lower tray 100 and the upper cover 300, so that the top surface and the bottom surface of the item to be packaged 200 are not directly in contact with the lower tray 100 and the upper cover 300, thereby achieving packaging protection for the item to be packaged 200 and further improving the yield of the item to be packaged 200 during transportation.

[0039] It should be noted that the item to be packaged 200 described above can be a laser radar product, a display product or other electronic product. In this embodiment, taking the packaging of a laser radar product as an example, the item to be packaged 200 can include a first part and a second part that are connected to each other. For example, the first part can be a plate body of the item to be packaged 200, and the plate body can be provided with components such as laser diodes, solid-state lasers, optical elements, and photoelectric conversion elements. The second part can be a connector of the item to be packaged 200, and the two are connected through a flexible circuit board, a cable, etc. The specific structure of the item to be packaged 200 can be set according to the actual structure of the product, and will not be repeated here.

[0040] In one embodiment, if Figure 2 and Figure 3 As shown, the above-mentioned receiving groove 10 includes a first receiving groove 11 and a second receiving groove 12. The first receiving groove 11 is used to receive the first part of the item to be packaged 200, and the second receiving groove 12 is used to receive the second part of the item to be packaged 200. The second receiving groove 12 is located on one side of the first receiving groove 11, and the second receiving groove 12 is connected to the first receiving groove 11.

[0041] In some embodiments, the lower tray 100 has a plurality of receiving grooves 10, and the upper cover 300 has a plurality of pressing parts 32, and the plurality of pressing parts 32 respectively correspond to the receiving grooves 10. The first receiving groove 11 and the second receiving groove 12 are arranged along the length direction X of the receiving groove 10, and the plurality of receiving grooves are arranged in parallel along the width direction Y of the receiving groove 10. Among them, there is a loading and unloading area 15 connecting the two first receiving grooves between two adjacent first receiving grooves 11, so that when the clamping part of the manipulator clamps the package 200, the clamping part can extend into the first receiving groove 11, avoiding interference between the clamping part and the lower tray 100, thereby improving the loading and unloading efficiency of the package 200.

[0042] In some embodiments, the shape of the receiving groove 10 is designed according to the shape of the item to be packaged. The shape of the first receiving groove 11 can be square, circular, elliptical, polygonal or other special shapes, which is not particularly limited here. Similarly, the shape of the second receiving groove 12 can be square, circular, elliptical, polygonal or other special shapes, which is not particularly limited here. It should be noted that the shape of the first receiving groove 11 can be the same as or different from the shape of the second receiving groove 12, which is not particularly limited here. Among them, the depth of the second receiving groove 12 can be less than or equal to the depth of the first receiving groove 11, as long as it can provide sufficient accommodation space for the second part of the item to be packaged 200.

[0043] like Figures 2 to 5 As shown, the number of the supporting parts 13 is at least two, for example Figure 1 and Figure 2 It is shown that the first receiving groove 11 is provided with four supporting parts 13. Each supporting part 13 is protruding from the bottom surface 10a of the first receiving groove 11, and is used to support the first part of the to-be-packaged item 200, so that the first part is suspended in the first receiving groove 11, so as to maintain a gap between the bottom surface 10a of the first receiving groove 11, and can avoid direct contact between the to-be-packaged item 200 and the bottom surface 10a of the first receiving groove 11. That is, there is a gap between the to-be-packaged item 200 and the lower tray 100 in the depth direction Z of the first receiving groove 11. In this way, the problem of the to-be-packaged item 200 being damaged due to the pressure of its own gravity when placed in the first receiving groove 11 can be avoided, thereby improving the yield rate of the to-be-packaged item 200.

[0044] Optionally, the support portion 13 is disposed at the edge of the first receiving groove 11. Specifically, the support portion 13 can be disposed at the corner of the edge of the first receiving groove 11, that is, at the edge. The edge of the first receiving groove 11 is the intersection of the length direction X and the width direction Y of the first receiving groove 11. Since the shape of the first receiving groove 11 is generally rectangular, and in order to ensure the supporting effect of the support portion 13 on the package 200, the support portion 13 can be respectively disposed at the four corners of the rectangle, that is, the number of the support portions 13 can be set to four.

[0045] like Figures 2 to 5As shown, the size of the first receiving groove 11 is greater than or equal to the size of the package 200 to be packaged, so that the first part of the package 200 can be accommodated in the first receiving groove 11. The edge of the first receiving groove 11 is adapted to the edge of the package 200. Specifically, the edge of the package 200 has a plurality of corners, and the corners of the package 200 are the intersections of the length direction X and the width direction Y of the package 200. Generally speaking, the upper and lower surfaces of the first part of the package 200 may be provided with many fragile parts, while the corners have fewer components, usually a flat plate surface. In order to avoid direct contact between the bottom surface of the package 200 and the bottom surface 10a of the first receiving groove 11, when the support portion 13 is provided at the corners of the first receiving groove 11, the protection effect of the package 200 is better.

[0046] like Figures 1 to 3 As shown, in some embodiments, the support portion 13 can be disposed at any position of the first receiving groove 11, for example, the support portion 13 can be disposed at the middle of the bottom surface 10a of the first receiving groove 11, or can be disposed at a position where the bottom surface 10a of the first receiving groove 11 is close to the side wall 10b of the first receiving groove 11. The number of the support portions 13 can be two, three, four or more, which can be set according to the actual situation of the package to be packaged, so that the support portion 13 can be supported at the board surface of the package 200 with fewer components, and no special limitation is made here.

[0047] like Figure 2 and Figure 3 As shown, the first receiving groove 1 is provided with an avoidance groove 121 recessed in the side wall 10b thereof, and the avoidance groove 121 extends from the supporting surface 101 of the lower tray 100 along the depth of the first receiving groove 11. The avoidance groove 121 can be in an arc shape, a nearly square shape, etc. The avoidance groove 121 avoids components, sharp corners, etc. on the package 200.

[0048] like Figures 1 to 3 As shown, the avoidance groove includes a first avoidance groove 1211 and a second avoidance groove 1212. A first avoidance groove 1211 is respectively arranged at the four corners of the first receiving groove 11, and the second avoidance groove 1212 is recessed in the side wall opposite to the second receiving groove and is located between the two first avoidance grooves. Figure 1 and Figure 2 It is shown that the second avoidance groove 1212 is only provided on one side of the first receiving groove 11. When the package 200 can be accommodated by the first receiving groove 11 only, the second avoidance groove 1212 can also be provided on other sides of the first receiving groove 11, which will not be further explained here.

[0049] In some embodiments, the shapes of the first avoidance groove 1211 and the second avoidance groove 1212 can be arc-shaped, approximately square-shaped, etc. The first avoidance groove 1211 avoids components, sharp corners, etc. on the package 200, and the second avoidance groove 1212 can prevent the first part of the package 200 from interfering with the side wall 10b of the first accommodating groove 11 when the package 200 is placed in the first accommodating groove 11, thereby affecting the packaging efficiency.

[0050] In some embodiments, the bottom surface 10a of the first receiving groove 11 is provided with a recessed portion 14, and the recessed portion 14 is arranged at the connection between the second receiving groove 12 and the first receiving groove 11. Since there may be other extended parts at the connection between the first part and the second part of the package 200, when the package 200 is placed on the lower tray 100, the recessed portion 14 can be used to avoid the package 200 to prevent it from interfering with the lower tray 100 and affecting the packaging efficiency of the package 200 and reducing the protective effect of the packaging assembly. The recessed portion 14 is arranged at the connection between the second receiving groove 12 and the first receiving groove 11. On the one hand, it is adapted to the product structure, and on the other hand, it increases the mechanical strength of the lower tray 100 in this area. The depth of the recessed portion 14 can be set according to the extended parts of the package 200, and is not particularly limited here.

[0051] like Figure 4 As shown, the main body 31 includes a plate 311 , a first limiting portion 312 and a second limiting portion 313 .

[0052] The plate body 311 is stacked on the side of the lower tray 100 having the receiving groove, that is, the plate body 311 is stacked on the top surface of the lower tray 100. The plate body 311 has a covering surface 301 facing the lower tray 100.

[0053] The first limiting portion 312 is convexly disposed on the side of the plate body 311 facing the lower tray 100, that is, the first limiting portion 312 is convexly disposed on the bottom surface of the plate body 311. The first limiting portion 312 is accommodated in the first receiving groove 11, and the pressing portion 32 is convexly disposed on the side of the first limiting portion 312 facing the bottom surface of the first receiving groove 11. The first limiting portion 312 cooperates with the first receiving groove 11 to improve the stability of the buckling of the lower tray 100 and the upper cover 300.

[0054] The second limiting portion 313 is protruded from the side of the plate 311 facing the lower tray 100, and is received in the second receiving groove 12. The second limiting portion 313 cooperates with the second receiving groove 12 to further improve the stability of the buckling of the lower tray 100 and the upper cover 300.

[0055] like Figures 2 to 5As shown, in the depth direction Z of the accommodating groove 10, the first limiting portion 312 cooperates with the first accommodating groove 11 to limit the accommodating space for accommodating the first part of the item to be packaged 200, and the second limiting portion 313 cooperates with the second accommodating groove 12 to limit the accommodating space for accommodating the second part of the item to be packaged 200, and the first limiting portion 312 and the second limiting portion 313 can enhance the mechanical strength of the upper cover 300. In this way, when the item to be packaged 200 is subjected to accidents such as vibration and collision during transportation, the item to be packaged 200 is prevented from being damaged by excessive shaking.

[0056] like Figures 1 to 3 As shown, the lower tray 100 also includes a support wall 102, which is connected to the outer periphery of the supporting surface 101 to support the supporting surface 101 and the accommodating groove 10 in the depth direction Z of the accommodating groove 10. It can also be said that the surroundings of the supporting surface 101 are folded to form the support wall 102, and the end of the support wall 102 extends outward (i.e., toward the surroundings) to form a first extension portion 102a. The upper cover also includes a rim 302 arranged around the edge of the covering surface 301, and the end of the rim 302 extends outward (i.e., toward the surroundings) to form a second extension portion 302a. When the upper cover 300 and the lower tray 100 cooperate with each other, the covering surface 301 and the supporting surface 101 are arranged opposite to each other, and the rim 302 and the support wall 102 are in contact with each other.

[0057] like Figures 2 to 4 As shown, the packaging assembly further includes a first clamping portion 41 and a second clamping portion 42. Specifically, the supporting wall 102 is provided with the first clamping portion 41, and the edge 302 is provided with the second clamping portion 42. When the upper cover 300 and the lower tray 100 are covered, the first clamping portion 41 and the second clamping portion 42 are mutually engaged and matched to fix the upper cover 300 and the lower tray 100, thereby improving the stability of the packaging assembly.

[0058] In some embodiments, one of the first clamping portion 41 and the second clamping portion 42 is a protrusion and the other is a groove to achieve the fixation of the two trays. That is, the first clamping portion 41 is a protrusion and extends toward the edge 302, and the second clamping portion 42 is a groove and is recessed away from the support wall 102. Alternatively, the first clamping portion 41 is a groove and is recessed away from the edge 302, and the second clamping portion 42 is a protrusion and extends toward the support wall 102. Among them, the protrusion can be elastically snapped into the groove. It should be noted that in addition to the above-mentioned fixing method of the packaging assembly, other clamping structures can also be used to fix the two trays, which will not be repeated here.

[0059] In one embodiment, the packaging assembly may include a plurality of packaging units 50 stacked on top of each other, each packaging unit 50 including a lower tray 100 and an upper cover 300, so that the occupied space of the packaging assembly can be reduced.

[0060] Therefore, the packaging assembly provided in the embodiment of the present application includes an upper cover and a lower tray, wherein the lower tray includes a receiving groove and a supporting portion, and the supporting portion is used to support the items to be packaged, so that a gap is maintained between the items to be packaged placed in the receiving groove and the bottom surface of the receiving groove, so as to avoid direct contact between the bottom surface of the items to be packaged and the bottom surface of the receiving groove, thereby avoiding the parts of the items to be packaged from being crushed by their own gravity, thereby improving the yield of the items to be packaged. The packaging assembly also includes an upper cover, which includes a main body and a pressing portion protruding from the main body, and in the depth direction of the receiving groove, the pressing portion and the supporting portion are arranged relative to each other to clamp the items to be packaged and limit the items to be packaged in the preset position of the packaging assembly, thereby avoiding damage to the items to be packaged due to vibration, collision, etc. during transportation, and further improving the yield of the items to be packaged.
