[0031] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0032] See also Figure 1 and Figure 2The present application discloses a tray 100, which includes a tray body 10, on which a plurality of first accommodating grooves 11 are arranged at intervals, and the first accommodating grooves 11 are used to accommodate products. The bottom wall 111 of the first accommodating groove 11 is provided with a first through hole 111a and a second through hole 111b, which are arranged through the thickness direction of the tray body 10, and the first through hole 111a and the first accommodating groove 11 are used to accommodate products together, and the second through hole 111b is located at the periphery of the first through hole 111a, and the second through hole 111b is configured to expose at least part of the product.

[0033] The tray 100 of the present application is provided with a plurality of first receiving grooves 11 on the tray body 10, and a first through hole 111a is provided on the groove bottom wall 111 to be used together with the first receiving groove 11 to receive the product, thereby achieving full fixation of the product, and a second through hole 111b is provided on the periphery of the first through hole 111a, so that at least part of the product can be exposed. In this way, when the product is placed in the first receiving groove 11, the appearance of the product can be inspected not only from one side of the tray 100, but also from the other side through the second through hole 111b by turning over the tray 100. In other words, by using the tray 100 of the present application, a comprehensive inspection of the product can be achieved by turning over the tray 100, avoiding the situation where the product needs to be turned over because one side of the product is completely blocked, thereby reducing the probability of damage to the appearance of the product, which is conducive to improving the inspection efficiency of the product, and further conducive to improving the production efficiency of the product.

[0034] Among them, multiple first receiving grooves 11 can be arranged at intervals along the length direction and width direction of the tray body 10, for example, there are 5, 6 or 7 first receiving grooves 11 arranged in the length direction of the tray body 10, and there are 2, 3 or 4 first receiving grooves 11 arranged in the width direction of the tray body 10. The specific number can be adjusted according to the actual load-bearing capacity of the pallet and inspection requirements, and is not limited in this embodiment.

[0035] It is understandable that the above-mentioned products may include but are not limited to camera products such as camera modules, lens barrels, motors, or components of electronic products such as circuit boards and batteries.

[0036] Taking the above-mentioned product as a camera module as an example, since the shapes of the two opposite surfaces of the camera module along the optical axis direction may be different, such as one side is a lens for transmitting light, and the other side is a circuit board structure for receiving images, when the camera module is placed in the first accommodating groove 11, the lens part can be extended into the first through hole 111a, and the first through hole 111a and the first accommodating groove 11 are used to accommodate the camera module together. Since the groove bottom wall 111 is also provided with a second through hole 111b for exposing part of the camera module, the side with the lens can also be observed through the second through hole 111b. In this way, when it is necessary to inspect the two opposite surfaces of the camera module along the optical axis direction, there is no need to take the camera module out of the tray 100 and then turn it over. The inspection of the two opposite surfaces of the camera module can be achieved by automatically or semi-automatically flipping the tray 100.

[0037] Furthermore, the second through hole 111b is arranged around the outer circumference of the first through hole 111a. That is, the second through hole 111b is arranged around the outer circumference of the first through hole 111a, so that the second through hole 111b can be arranged more compactly relative to the first through hole 111a. Exemplarily, the second through hole 111b can be in the shape of a long strip, and the length direction of the long strip second through hole 111b can extend around the outer circumference of the first through hole 111a, relative to the arrangement in which the length direction of the second through hole 111b extends along the radial direction of the first through hole 111a, such an arrangement can appropriately increase the exposed area of ​​the product, making it easier to inspect the product.

[0038] It can be understood that a camera product such as a camera module may have multiple steps along the optical axis and present an irregular state. In order to facilitate more stable accommodating of products, in some embodiments, the bottom wall 111 of the groove may also be provided with a sink 112, and the sink 112 is configured to accommodate at least part of the product. The sink 112 has a first surface 112a opposite to the bottom wall 111, and the first surface 112a is provided with a first through hole 111a. Since the sink 112 is provided on the bottom wall 111 of the groove, the sink 112 can be used to accommodate part of the product, so that the side wall of the sink 112 can play a certain restraining role on the product, thereby facilitating the stability of the product placed in the first accommodating groove 11. In addition, since the sink 112 is formed by the bottom wall 111 of the first accommodating groove 11 being recessed downward and used to accommodate part of the product, it is beneficial to reduce the space occupied by the product in the first accommodating groove 11, and avoid the situation that the first accommodating groove 11 is too deep in order to accommodate the product as much as possible, thereby increasing the thickness of the tray 100.

[0039] In some possible implementations, there are multiple second through holes 111b, and the multiple second through holes 111b are arranged around the center of the first through hole 111a at intervals. When the number of second through holes 111b is multiple, the first through hole 111a and the second through hole 111b are connected at multiple locations while the product can have a larger exposed area, so that the first receiving groove 11 has sufficient structural strength as a whole.

[0040] Optionally, the number of the second through holes 111 b may be two, three, four, etc. In order to maintain the force balance of the first receiving groove 11 , the plurality of second through holes 111 b may be evenly distributed around the first through hole 111 a .

[0041] Furthermore, the first receiving groove 11 may be a square groove, and the second through holes 111b are arranged corresponding to the four corners of the first receiving groove 11. By setting the first receiving groove 11 as a square groove, it can be more adapted to the requirements of the product as a camera module, making the tray 100 more specialized. Of course, in some other embodiments, the first receiving groove 11 may be a circle or other irregular shapes, which can be adjusted according to product requirements.

[0042] Taking the first accommodating groove 11 as a square groove as an example, at this time, when the number of the second through holes 111b is multiple, the second through holes 111b can be set according to the corners of the square groove. For example, when there are two second through holes 111b, the two second through holes 111b can be set in the form of diagonal lines at the corners of the square groove; for example, when there are four second through holes 111b, the four second through holes 111b are respectively set corresponding to the four corners of the square groove, so that the structural design of the first accommodating groove 11 is more balanced.

[0043] Optionally, the shape of the second through hole 111b can be square, circular, long or L-shaped, etc., as long as it can expose the part of the product that needs to be inspected. The specific size and shape can be adjusted according to the type of product and the inspection requirements, and are not specifically limited in this embodiment. Preferably, the shape of the second through hole 111b can be L-shaped. The L-shaped second through hole 111b design can make the opening area of ​​the second through hole 111b large enough, so that a larger area of ​​the product can be exposed, thereby facilitating the inspection of the product. In particular, when the first accommodating groove 11 is a square groove, the L-shaped second through hole 111b can better adapt to the corners of the square-shaped first accommodating groove 11, so as to fully utilize the space of the groove bottom wall 111.

[0044] See also Figure 2 and Figure 3In some embodiments, the bottom wall 111 of the groove may also be provided with a plurality of limiting portions 113, each limiting portion 113 extending along the depth direction of the first through hole 111a to the first surface 112a, each limiting portion 113 being located at the periphery of the first through hole 111a, and each limiting portion 113 blocking two adjacent second through holes 111b, and the limiting portion 113 is configured to limit the position of the product in the sink 112. By providing the limiting portion 113 extending to the first surface 112a on the bottom wall 111 of the groove, on the one hand, the position of the product in the sink 112 can be limited to achieve the stability of product placement; on the other hand, the limiting portion 113 is located between two adjacent through holes, which can strengthen the connection between the bottom wall 111 of the groove and the first surface 112a, thereby improving the overall structural strength of the first accommodating groove 11.

[0045] Optionally, the limiting portion 113 may be a limiting protrusion, a limiting rib or other structure arranged on the groove bottom wall 111, as long as the limiting portion 113 can both limit the product and strengthen the structural strength of the connection between the groove bottom wall 111 and the first surface 112a.

[0046] In some possible implementations, in order to facilitate placing the product in the first accommodating groove 11, the limiting portion 113 has a guide surface 113a, the guide surface 113a is inclined from the groove bottom wall 111 toward the first surface 112a, and the guide surface 113a is configured to guide the product into the sink 112. By providing the guide surface 113a on the limiting portion 113, a guiding effect is provided when the product is placed in the sink 112, so as to facilitate the smoothness of placing the product in the sink 112.

[0047] In addition, in addition to the guide surface 113 a of the limiting portion 113 , the edge of the sink 112 may also be provided with a guide surface 113 a , so as to prevent the product from hitting a sharp edge during placement and affecting the appearance of the product.

[0048] It can be understood that the bottom wall 111 of the first receiving groove 11 is provided with a first through hole 111a and a plurality of second through holes 111b. If the distance between the first hole and the second through hole 111b is too close, the solid part between the two will be too thin, thereby affecting the structural strength of the first receiving groove 11. Therefore, in order to strengthen the connection strength of the solid part between the first through hole 111a and the second through hole 111b, in some embodiments, refer to Figure 2The outer peripheral wall of the first through hole 111a is provided with a thickened portion 114, and the thickened portion 114 is configured to protrude toward the second through hole 111b. In this way, the thickness of the solid part between the first through hole 111a and the second through hole 111b can be thickened, which is conducive to improving the structural strength of the first receiving groove 11, thereby improving the stability of the first receiving groove 11 carrying the product. In addition, the thickened portion 114 is configured to protrude toward the second through hole 111b, which can avoid the phenomenon of collision with the product placed in the first through hole 111a.

[0049] In some possible implementations, the tray body 10 is further provided with a weight-reducing hole 12, which is located at the periphery of the second through hole 111b. By providing the weight-reducing hole 12 on the tray body 10, the tray body 10 can be made lighter, thereby making the tray 100 lighter as a whole. In addition, during the molding process of the tray 100, materials can be saved, thereby helping to reduce material costs.

[0050] Optionally, the number of the weight-reducing holes 12 can be consistent with the number of the second through holes 111b and can be arranged corresponding to the second through holes 111b. In order to facilitate the description of the arrangement position of the weight-reducing holes 12, the first accommodating groove 11 is a square groove and the plurality of second through holes 111b are respectively arranged at the four corners of the square groove.

[0051] As can be seen from the above, a limiting portion 113 is provided between two adjacent second through holes 111b, and the limiting portion 113 extends from the groove bottom wall 111 to the first surface 112a. Similarly, a solid portion corresponding to the limiting portion 113 is also provided between two adjacent weight-reducing holes 12. In one example, the solid portion is flush with the surface of the disk body 10. In another example, the solid portion can be flush with the groove bottom wall 111, that is, in this embodiment, the weight-reducing hole 12 can be connected with the first accommodating groove 11. In this way, on the basis of being able to play a weight-reducing role, it can be applied to products of larger sizes. At this time, the product can also cover at least part of the weight-reducing hole 12, so that the weight-reducing hole 12 can also be used to expose at least part of the product, which is more convenient for product inspection.

[0052] As can be seen from the foregoing, the shape of the second through hole 111b can be preferably L-shaped. In this case, the shape of the weight-reducing holes 12 can also be all L-shaped, so that the weight-reducing holes 12 also have a larger opening area, which is more conducive to the lightweight design of the tray 100. Of course, the shape of the weight-reducing holes 12 can be partially L-shaped and partially square, for example, two adjacent weight-reducing holes 12 are square, so that less material can be removed from the tray body 10, so that the retained solid part can carry the product more stably.

[0053] It can be understood that the product of this embodiment can be a camera product such as a camera module or a motor. Such products usually have leads for electrical connection. In order to accommodate the lead structure, in some possible implementations, the disk body 10 is also provided with a plurality of second accommodating grooves 13. The plurality of second accommodating grooves 13 are arranged one-to-one with the plurality of first accommodating grooves 11, and the second accommodating grooves 13 and the first accommodating grooves 11 are arranged adjacent to each other along the first direction. The second accommodating grooves 13 are connected to the first accommodating grooves 11 to accommodate the product together. In this way, the product can be accommodated more completely, and the situation where the partial structure of the product has nowhere to be placed and affects the inspection of the product will not be caused. Moreover, the product can be placed better, thereby playing a certain protective role for the product.

[0054] It can be understood that the pallet 100 has a plurality of first receiving grooves 11 arranged along different directions, so the second receiving grooves 13 are also arranged along different directions, and the plurality of second receiving grooves 13 arranged at intervals along a certain direction can be interconnected. On the one hand, part of the material between the second receiving grooves 13 can be removed to reduce the weight of the pallet 100; on the other hand, it can also facilitate the processing continuity of the second receiving grooves 13.

[0055] In order to further reduce the weight of the tray 100, in some embodiments, refer to Figure 4 A weight-reducing groove 14 is provided on the side of the tray body 10 away from the second receiving groove 13. The weight-reducing groove 14 is provided corresponding to the second receiving groove 13, and the depth of the weight-reducing groove 14 along the thickness direction of the tray body 10 is greater than the depth of the second receiving groove 13. By providing the weight-reducing groove 14 on the side of the tray body 10 away from the second receiving groove 13, the weight of the tray 100 can be further reduced, thereby making the tray 100 lighter.

[0056] As can be seen from the foregoing, the tray 100 provided in the embodiment of the present application inspects the products carried therein by flipping the tray 100. In order to prevent the products from falling out of the first receiving groove 11, the tray 100 further includes a cover (not shown), which is configured to cover and connect to the tray body 10 to limit the position of the products on the tray body 10. That is, the cover is connected with the tray 100 to fix the products on the tray 100. In this way, after inspecting one side of the product, when the other side of the product is inspected by flipping the tray 100, the product will not fall off due to the effect of the cover, so that the product can be effectively fixed, the smoothness of the product inspection process is guaranteed, and the inspection efficiency of the product is improved.

[0057] The pallet disclosed in the embodiment of the present application is introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the pallet of the present application and its core idea; at the same time, for general technicians in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
