Description

Technical Field

[0001] This application belongs to the technical field of material transportation, and particularly relates to a tray. Background Art

[0002] A printed circuit board (PCB) includes a substrate and electronic devices soldered on both the front and back sides of the substrate. When inspecting the product quality of a PCB, it is necessary to inspect both sides separately to ensure that the required electronic devices are correctly soldered to the substrate. Thus, during the inspection process, the PCB needs to be flipped.

[0003] Currently, to inspect the front and back sides of a PCB, a positive-placement tray and a reverse-placement tray are usually used to respectively support the back side and the front side of the PCB. Setting up two types is not convenient for management, and during inspection, it is necessary to transfer the PCB between different types of trays, resulting in low inspection efficiency. Summary of the Utility Model

[0004] In view of the above situation, it is necessary to provide a tray that can facilitate management and improve the inspection efficiency of PCBs.

[0005] An embodiment of this application provides a tray. The tray includes a first surface and a second surface that are oppositely arranged in the thickness direction. The first surface is provided with a first groove, and the second surface is provided with a second groove. The first groove is adapted to the outer shape of the workpiece when the workpiece is placed with its back side facing the tray, and the second groove is adapted to the outer shape of the workpiece when the workpiece is placed with its front side facing the tray.

[0006] In this tray, both the first groove and the second groove can be used to accommodate the workpiece. On the one hand, only one type of tray is required during the inspection process of the workpiece, which is convenient for management. On the other hand, during the inspection process of the workpiece, there is no need to transfer the workpiece between different types of trays, which is beneficial to improving the inspection efficiency of the workpiece.

[0007] In an optional embodiment of this application, the first groove and the second groove are correspondingly arranged. When multiple trays are stacked, the first grooves and the second grooves of any two adjacent trays communicate with each other, so that multiple trays can be stacked and used. This is beneficial to improving the inspection efficiency of the front and back sides of the workpiece.

[0008] In an optional embodiment of this application, the tray includes a main body part and a convex part. The main body part includes a first surface and a second surface, and the convex part protrudes from the second surface. The second groove is arranged on the convex part. Arranging the convex part on the second surface of the main body part and arranging the second groove on the convex part enables the tray to maintain a smaller thickness at positions where the second groove does not need to be opened, which is beneficial to saving the materials required for producing the tray, reducing the weight of the tray, saving costs on the one hand, and facilitating the flipping operation on the other hand.

[0009] In an alternative embodiment of the present application, the first surface is provided with a positioning groove, and the convex portion includes a positioning portion, the size of the positioning portion being adapted to the size of the positioning groove. In the state where a plurality of trays are stacked, for any two adjacent trays, the positioning portion of one tray extends into the positioning groove of the other tray, which is beneficial to reducing the possibility of mutual displacement between two adjacent trays and improving the stability of the stacked trays.

[0010] In an alternative embodiment of the present application, the tray includes a surrounding portion, the surrounding portion being connected to the edge of the main body portion in a surrounding manner and surrounding the second surface. The surrounding portion is provided with a concave portion, the concave portion being recessed in a direction approaching the convex portion. The concave portion includes a first dimension portion and a second dimension portion, the size of the first dimension portion being larger than that of the second dimension portion, and the second dimension portion being located on the side of the first dimension portion away from the second surface. The first dimension portion encloses a first receiving groove, the second dimension portion encloses a second receiving groove, and there is a stepped surface between the first receiving groove and the second receiving groove. In the state where a plurality of trays are stacked, for any two adjacent trays, the second dimension portion of one tray is disposed in the first receiving groove of the other tray, and the second dimension portion abuts against the stepped surface. When the trays are stacked, the cooperation between the second dimension portion and the first receiving groove can play a positioning role, which is beneficial to aligning the first groove and the second groove. Moreover, after the trays are stacked, the cooperation between the second dimension portion and the first receiving groove is beneficial to reducing the possibility of mutual displacement between two adjacent trays and improving the stability of the stacked trays.

[0011] In an alternative embodiment of the present application, the first groove includes a first part and a second part. Along the thickness direction of the tray, the depth of the first part is less than that of the second part. The second part can be used to avoid interfering with some structures on the workpiece, improve the stability of the workpiece when disposed in the first groove, and also be beneficial to reducing the possibility of damage to some structures on the workpiece caused by collision with the surrounding wall of the first groove during the flipping process.

[0012] In an alternative embodiment of the present application, the second groove includes a first region and a second region. Along the thickness direction of the tray, the depth of the first region is less than that of the second region. The second region can be used to avoid interfering with some structures on the workpiece, improve the stability of the workpiece when disposed in the second groove, and also be beneficial to reducing the possibility of damage to some structures on the workpiece caused by collision with the surrounding wall of the second groove during the flipping process.

[0013] In an alternative embodiment of the present application, for each tray, a plurality of first grooves and second grooves are provided. This is beneficial to placing a plurality of workpieces on the same tray and improving the inspection efficiency of the workpieces.

[0014] In an alternative embodiment of the present application, a plurality of first grooves are arranged side by side, and the first surface is further provided with a third groove, the third groove communicating with the plurality of side-by-side first grooves. This facilitates inserting or removing the workpiece into or from the first groove at the third groove.

[0015] In an alternative embodiment of the present application, a plurality of second slots are arranged side by side, and a fourth slot is further provided on the second surface. The fourth slot communicates with the plurality of second slots arranged side by side. This facilitates placing or removing the workpiece into or from the second slots at the fourth slot.

For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to specific circumstances.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0053] In the description of the embodiments of the present application, technical terms such as "first" and "second" are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity, specific order or primary-secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "a plurality" is more than two, unless otherwise specifically limited.

[0054] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Without conflict, the various embodiments in the present application can be combined with each other.

[0055] An embodiment of the present application provides a tray. The tray includes a first surface and a second surface oppositely arranged in the thickness direction. The first surface is provided with a first groove, and the second surface is provided with a second groove. The first groove is adapted to the outer shape of the workpiece when the workpiece is placed with its reverse side facing the tray, and the second groove is adapted to the outer shape of the workpiece when the workpiece is placed with its front side facing the tray.

[0056] In this tray, both the first groove and the second groove can be used to accommodate the workpiece. On the one hand, only one type of tray is required during the inspection process of the workpiece, which is convenient for management. On the other hand, during the inspection process of the workpiece, there is no need to transfer the workpiece between different types of trays, which is beneficial to improving the efficiency of inspecting the workpiece.

[0057] The following further describes the embodiments of the present application with reference to the accompanying drawings.

[0058] As Figure 1 and Figure 2 shown, an embodiment of the present application provides a tray 100. The tray 100 includes a first surface 111 and a second surface 112 oppositely arranged in the thickness direction. The first surface 111 is provided with a first groove 1111, and the second surface 112 is provided with a second groove 121. The first groove 1111 is adapted to the outer shape of the workpiece 200 when the workpiece 200 is placed with its reverse side facing the tray 100, and the second groove 121 is adapted to the outer shape of the workpiece 200 when the workpiece 200 is placed with its front side facing the tray 100.

[0059] In this tray 100, both the first groove 1111 and the second groove 121 can be used to accommodate the workpiece 200. On the one hand, only one type of tray is required during the inspection process of the workpiece 200, which is convenient for management. On the other hand, during the inspection process of the workpiece 200, there is no need to transfer the workpiece 200 between different types of trays 100, which is beneficial to improving the efficiency of inspecting the workpiece 200.

[0060] It should be noted that the front and back sides of the workpiece 200 are two opposite sides of the workpiece 200. In addition, the tray 100 provided in the embodiments of the present application is applicable to workpieces 200 including but not limited to PCBs 210.

[0061] In some embodiments, the first groove 1111 and the second groove 121 are correspondingly arranged. Thus, when multiple trays 100 are stacked, the first groove 1111 of any two adjacent trays 100 communicates with the second groove 121, so that multiple trays 100 can be stacked and used. Specifically, multiple trays 100 can be prepared according to the number of workpieces 200 to be detected. Each tray 100 is placed with the first surface 111 facing upward, and the workpiece 200 is placed in the first groove 1111 with the front side facing upward to facilitate the inspection of the front side of the workpiece 200. After the front side of the workpiece 200 is inspected, the multiple trays 100 are stacked so that the first groove 1111 of two adjacent trays 100 communicates with the second groove 121, and an empty tray 100 without a workpiece 200 is covered on the top of the stacked trays 100. Subsequently, the stacked trays 100 are flipped so that the trays 100 are placed with the second surface 112 facing upward. As the trays 100 are flipped, the workpiece 200 falls from the first groove 1111 into the second groove 121. At this time, the back side of the workpiece 200 faces upward, and the back sides of the workpieces 200 in each tray 100 can be inspected one by one.

[0062] In this embodiment, when at least two trays 100 are stacked, the first groove 1111 of two adjacent trays 100 communicates with the second groove 121, and the workpiece 200 is received in the first groove 1111 or the second groove 121. After the tray 100 is flipped, the workpiece 200 can be driven to flip, which is beneficial to improving the inspection efficiency of the front and back sides of the workpiece 200.

[0063] In some embodiments, as Figure 2 shown, the tray 100 includes a main body portion 11 and a convex portion 12. The main body portion 11 includes a first surface 111 and a second surface 112. The convex portion 12 protrudes from the second surface 112, and the second groove 121 is provided in the convex portion 12. To receive the workpiece 200, both the first groove 1111 and the second groove 121 need to have a certain depth, which poses a certain requirement for the thickness of the tray 100. By providing the convex portion 12 on the second surface 112 of the main body portion 11 and arranging the second groove 121 in the convex portion 12, the tray 100 can maintain a smaller thickness at the position where the second groove 121 does not need to be opened, which is beneficial to saving the materials required for producing the tray 100, reducing the weight of the tray 100, saving costs on the one hand and facilitating the flipping operation on the other hand.

[0064] In some embodiments, as Figures 1 to 3As shown, the first surface 111 is provided with a positioning groove 1112, and the convex portion 12 includes a positioning portion (not shown in the figure). The size of the positioning portion is adapted to the size of the positioning groove 1112. In the state where a plurality of trays 100 are stacked, for any two adjacent trays 100, the positioning portion of one tray 100 extends into the positioning groove 1112 of the other tray 100, which is beneficial to reducing the possibility of mutual displacement between the two adjacent trays 100 and improving the stability of the stacked trays 100.

[0065] In some embodiments, the positioning portion is columnar, including a square column and a cylindrical column. One end of the positioning portion away from the main body portion 11 is used to cooperate with the positioning groove 1112, and one end of the positioning portion close to the main body portion 11 is used to limit the workpiece 200. The cooperation between the positioning portion and the positioning groove 1112 may be that the height value of the positioning portion is slightly greater than the depth value of the positioning groove 1112.

[0066] In some embodiments, the positioning portion is a stepped boss. One end of the positioning portion away from the main body portion 11 is the upper step, which is used to cooperate with the positioning groove 1112, and one end of the positioning portion close to the main body portion 11 is the lower step, which is used to limit the workpiece 200. The cooperation between the positioning portion and the positioning groove 1112 may be that the width value of the lower step of the positioning portion is slightly greater than the width value of the positioning groove 1112.

[0067] In some embodiments, the positioning portion is frustum-shaped. One end of the positioning portion away from the main body portion 11 is the upper frustum, which is used to cooperate with the positioning groove 1112, and one end of the positioning portion close to the main body portion 11 is the lower frustum, which is used to limit the workpiece 200. The cooperation between the positioning portion and the positioning groove 1112 may be that the cross-sectional diameter value of the lower frustum of the positioning portion is slightly greater than the width value of the positioning groove 1112.

[0068] In some embodiments, the first surface 111 is provided with a positioning hole, and the second surface 112 is provided with a positioning post. In the state where the trays 10 are stacked, the positioning post is inserted into the positioning hole.

[0069] In some embodiments, in the state where the trays 100 are stacked, for any two adjacent trays 100, the convex portion 12 of one tray 100 is in contact connection with the first surface 111 of the other tray 100, which is beneficial to reducing the possibility that the workpiece 200 falls out of the first groove 1111 or the second groove 121 from the gap between the two trays 100 during the flipping process.

[0070] In some embodiments, as Figure 3 shown, the positioning groove 1112 communicates with the first groove 1111.

[0071] In some embodiments, as Figure 2 shown, the tray 100 includes a surrounding portion 13. The surrounding portion 13 is enclosed and connected to the edge of the main body portion 11, and the surrounding portion 13 surrounds the second surface 112.

[0072] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the enclosing part 13 is provided with a concave part 131. The concave part 131 is recessed in the direction close to the convex part 12. The concave part 131 includes a first dimension part 1311 and a second dimension part 1312. The dimension of the first dimension part 1311 is larger than that of the second dimension part 1312. The second dimension part 1312 is located on the side of the first dimension part 1311 away from the second surface 112. The first dimension part 1311 encloses a first receiving groove 131a, and the second dimension part 1312 encloses a second receiving groove 131b. There is a stepped surface 1313 between the first receiving groove 131a and the second receiving groove 131b. In the state where a plurality of trays 100 are stacked, for any two adjacent trays 100, the second dimension part 1312 of one tray 100 is arranged in the first receiving groove 131a of the other tray 100, and the second dimension part 1312 abuts against the stepped surface 1313. The cooperation between the second dimension part 1312 and the first receiving groove 131a can play a positioning role, which is beneficial to align the first groove 1111 and the second groove 121. And after the trays 100 are stacked, the cooperation between the second dimension part 1312 and the first receiving groove 131a is beneficial to reduce the possibility of mutual displacement between two adjacent trays 100 and improve the stability of the stacked trays 100.

[0073] In some embodiments, the main body part 11, the convex part 12 and the enclosing part 13 are integrally formed.

[0074] In some embodiments, such as Figure 3 shown, the first groove 1111 includes a first part 1111a and a second part 1111b. Along the thickness direction of the tray 100, the depth of the first part 1111a is less than that of the second part 1111b. The second part 1111b can be used to avoid some structures on the workpiece 200, improve the stability when the workpiece 200 is arranged in the first groove 1111, and is also beneficial to reduce the possibility that some structures on the workpiece 200 collide with the surrounding wall of the first groove 1111 and are damaged during the flipping process. Combining Figure 7 shown, taking the workpiece 200 as the PCB 210 as an example, the PCB 210 includes a substrate 211 and electronic devices 212 arranged on the substrate 211. The first part 1111a receives the substrate 211, and the second part 1111b avoids the electronic devices 212, thereby improving the stability when the PCB 210 is placed in the first groove 1111, and is also beneficial to reduce the possibility that the electronic devices 212 are damaged due to collision with the surrounding wall of the first groove 1111 during the flipping process.

[0075] In some embodiments, such as Figure 6As shown in the figure, the second slot 121 includes a first area 121a and a second area 121b. Along the thickness direction of the tray 100, the depth of the first area 121a is less than that of the second area 121b. The second area 121b can be used to avoid interfering with some structures on the workpiece 200, improving the stability of the workpiece 200 when it is placed in the second slot 121, and also reducing the possibility of damage to some structures on the workpiece 200 due to collision with the surrounding wall of the second slot 121 during the flipping process. Combined with Figure 7 As shown in the figure, taking the workpiece 200 as the PCB 210 as an example, the first area 121a houses the substrate 211, and the second area 121b avoids interfering with the electronic device 212, thereby improving the stability of the PCB 210 when it is placed in the second slot 121, and also reducing the possibility of damage to the electronic device 212 due to collision with the surrounding wall of the second slot 121 during the flipping process.

[0076] In some embodiments, such as Figure 1 and Figure 2 As shown in the figure, there are multiple first slots 1111 and second slots 121. This is beneficial for placing multiple workpieces 200 on the same tray 100 and improving the inspection efficiency of the workpieces 200.

[0077] In some embodiments, such as Figure 1 As shown in the figure, multiple first slots 1111 are arranged side by side. The first surface 111 is also provided with a third slot 1113, and the third slot 1113 communicates with the multiple first slots 1111 arranged side by side, facilitating the insertion or removal of the workpiece 200 into or from the first slots 1111 at the third slot 1113.

[0078] In some embodiments, such as Figure 2 As shown in the figure, multiple second slots 121 are arranged side by side. The second surface 112 is also provided with a fourth slot 122, and the fourth slot 122 communicates with the multiple second slots 121 arranged side by side, facilitating the insertion or removal of the workpiece 200 into or from the second slots 121 at the fourth slot 122.

[0079] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered within the disclosure scope of the present application.
