Description

Technical Field

[0001] This application relates to the field of PCBA board technology, and in particular to a PCBA loading tray. Background Technology

[0002] In the PCBA assembly process, the PCBA is usually first mounted on a mounting plate, and then multiple mounting plates containing PCBA boards are fixed on a loading tray to achieve batch mounting of multiple PCBA boards and increase the mounting density of PCBA boards.

[0003] In the prior art, the front and back sides of the loading tray are usually used to assemble multiple mounting plates, and screw holes need to be opened on both sides of the loading tray to fix the mounting plates with screws.

[0004] However, because the screw holes on both sides of the loading tray are prone to overlap or proximity during installation, once a mounting plate on one side is secured with screws, the screw holes on the opposite side will be blocked by the already installed mounting plate. This prevents the mounting plate on the opposite side from being installed smoothly, necessitating a reduction in the number of mounting plates in the corresponding area. Consequently, the actual loading capacity of the loading tray for mounting plates is reduced, resulting in a significant deficiency. Utility Model Content

[0005] To increase the loading capacity of the loading disk, this application provides a PCBA loading disk.

[0006] The PCB loading tray provided in this application adopts the following technical solution:

[0007] A PCBA loading tray includes a tray body. Multiple mounting plates are disposed on opposite ends of the tray body. The mounting plate on one end is designated as mounting plate one, and the mounting plate on the other end is designated as mounting plate two. Mounting plate one and its corresponding mounting plate two are staggered on the tray body. The contact surfaces of mounting plate one and its corresponding mounting plate two with the tray body have non-overlapping areas. Each mounting plate one and mounting plate two has a first screw hole in its non-overlapping area for screws to pass through, thereby fixing mounting plate one and mounting plate two to the tray body respectively.

[0008] By adopting the above technical solution, during installation, the worker places mounting plate one and mounting plate two alternately on the disk body. Then, the worker can fix the mounting plate to the disk body through the first screw hole in the non-overlapping area. This avoids the screws not being able to be driven in smoothly due to the overlap of mounting plate one and mounting plate two, ensuring that the mounting plates on both sides can be installed smoothly and increasing the loading capacity of the loading disk.

[0009] Optionally, the contact surfaces of the first mounting plate and the corresponding second mounting plate with the disc body have overlapping areas, and both the first mounting plate and the second mounting plate have second screw holes for screws to pass through in the overlapping areas, and both the first mounting plate and the second mounting plate have clearance notches that communicate with the screw holes in the overlapping areas.

[0010] By adopting the above technical solution, after mounting plate one and mounting plate two are placed alternately, the second screw hole in the overlapping area can be exposed through the notch on the opposite mounting plate, so that the screw can be installed smoothly in the overlapping area of ​​the mounting plate.

[0011] Optionally, the second mounting plate is symmetrically distributed along the central axis of the disk body relative to the corresponding first mounting plate.

[0012] By adopting the above technical solution, mounting plate two and mounting plate one are symmetrically distributed along the central axis of the disk body, which enables the staggered layout of mounting plates on the opposite surface of the disk body, so that the mounting plates are neatly arranged on the disk body, reducing the possibility of the first screw hole or the second screw hole being blocked due to the messy layout.

[0013] Optionally, the edges of the notch are rounded.

[0014] By adopting the above technical solution, the rounded notch can reduce stress concentration at the notch, reduce the possibility of cracking and damage caused by sharp edges during long-term use or stress, and extend the service life of the mounting plate.

[0015] Optionally, each of the two opposite end faces of the disk body is provided with a positioning frame, and the positioning frame is provided with a positioning groove corresponding to each of the multiple mounting plates.

[0016] By adopting the above technical solution, when installing the mounting plate, the worker places the mounting plate in the positioning groove for initial positioning, which reduces the alignment adjustment time during the installation process and improves the assembly efficiency of the mounting plate.

[0017] Optionally, the positioning frame can be detachably connected to the disk body via a connecting component.

[0018] By adopting the above technical solution, when the positioning frame is worn, deformed, or the indicator marks are blurred, the worker only needs to remove the damaged positioning frame from the disk body through the connecting component, without replacing the entire loading disk, which improves the convenience of worker maintenance and reduces maintenance costs.

[0019] Optionally, the connecting assembly includes a plurality of plug-in posts disposed on the positioning frame. The disk body has plug-in slots that engage with the plurality of plug-in posts. A plurality of elastic strips are evenly disposed circumferentially on the end face of the plug-in post away from the positioning frame. Each elastic strip has a hook portion at its end and a transition slope on each hook portion. When the elastic strip is inserted into the plug-in post and is in its natural state, the elastic strip abuts against the inner wall of the plug-in slot, and the hook portion extends out of the plug-in slot and abuts against the surface of the disk body.

[0020] By adopting the above technical solution, when disassembling the damaged trigger, the worker first pinches multiple hook parts to make them detach from the disc body, then pushes the hook parts to extend them into the insertion slot, and finally pulls the positioning frame outward to drive the insertion post out of the insertion slot, thus achieving the disassembly of the damaged positioning frame.

[0021] When installing the positioning frame, the worker first aligns the plug-in post with the plug-in slot, and then uses the guiding effect of the transition slope to insert the plug-in post into the plug-in slot. At this time, the hook part is squeezed by the inner wall of the plug-in slot, causing the elastic strip to be in a state of inward contraction. When the hook part extends out of the plug-in slot, the elastic strip opens outward with its own elasticity, so that the hook part abuts against the outer surface of the disc, thus realizing the installation of the positioning frame.

[0022] Optionally, the projections of the multiple insertion posts on the two positioning frames onto the disk body are staggered, and each positioning frame is provided with an avoidance groove for the hooking part to hook onto.

[0023] By adopting the above technical solution, the staggered arrangement of the plug-in posts on the two positioning frames and the opening of the clearance groove ensure that the disassembly and assembly of the two positioning frames are not affected by each other, thus ensuring a smooth and efficient disassembly and assembly process.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. This application arranges mounting plate one and mounting plate two in an alternating manner and opens notches on the mounting plates. Multiple first screw holes are all located in non-overlapping areas, and the second screw holes located in overlapping areas are connected to the notches on the mounting plates. Therefore, there is no situation where the screw holes are blocked by the mounting plate body. During installation, the worker can smoothly screw the screws into the disc body through the first screw holes and the second screw holes, thereby realizing the smooth installation of the mounting plate on the disc body and increasing the loading capacity of the loading disc for the mounting plate.

[0026] 2. By setting a positioning frame and positioning groove, this application allows workers to place the mounting plate in the positioning groove for initial positioning during installation, reducing the alignment adjustment time during installation and improving the assembly efficiency of the mounting plate.

[0027] 3. By setting up a connecting component, when the positioning frame is worn, deformed, or the indicator marks are blurred, the worker only needs to remove the damaged positioning frame from the disk body through the connecting component, without replacing the entire loading disk, which improves the convenience of worker maintenance and reduces maintenance costs.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a PCBA loading disk.

[0035] Example 1

[0036] Reference Figure 1 and Figure 2 A PCBA loading tray includes a tray body 1. Each of the opposite ends of the tray body 1 is fitted with a plurality of mounting plates 2 by screws. In this embodiment, each end of the tray body 1 is fitted with 8 mounting plates 2. The mounting plate 2 on the front of the tray body 1 is mounting plate one 21, and the mounting plate 2 on the back of the tray body 1 is mounting plate two 22. The structures of mounting plate one 21 and mounting plate two 22 are the same. Each mounting plate has mounting holes (not shown in the figure) for mounting PCBA boards at its four edges.

[0037] Reference Figure 1 and Figure 2Mounting plate 1 21 and corresponding mounting plate 22 are staggered on the disk body 1. The contact surfaces of mounting plate 1 21 and corresponding mounting plate 22 with the disk body 1 have non-overlapping areas. Mounting plate 1 21 and mounting plate 22 are provided with first screw holes 23 for screws to pass through in the non-overlapping areas. In this embodiment, each mounting plate 2 is provided with three first screw holes 23.

[0038] Reference Figure 1 and Figure 2 The contact surfaces of mounting plate 1 21 and corresponding mounting plate 22 with the disk body 1 have overlapping areas, and both mounting plate 1 21 and mounting plate 22 have second screw holes 24 for screws to pass through in the overlapping areas. In this embodiment, each mounting plate 2 has one second screw hole 24. Both mounting plate 1 21 and mounting plate 22 have clearance notches 3 that communicate with the screw holes in the overlapping areas. The second screw hole 24 on mounting plate 1 21 communicates with the notch 3 on mounting plate 22, and the second screw hole 24 on mounting plate 22 communicates with the notch 3 on mounting plate 1 21.

[0039] During installation, since the multiple first screw holes 23 are all in non-overlapping areas, and the second screw holes 24 in overlapping areas are connected to the notch 3 on the mounting plate 2, there is no situation where the screw holes are blocked by the mounting plate 2 body. During installation, the worker can smoothly screw the screws into the disc body 1 through the first screw holes 23 and the second screw holes 24, thereby realizing the smooth installation of the mounting plate 2 on the disc body 1 and increasing the loading capacity of the loading disc on the mounting plate.

[0040] Reference Figure 1 and Figure 2 In order to further optimize the arrangement of the mounting plate 2 on the disk body 1, the mounting plate 22 is symmetrical about 180° with respect to the corresponding mounting plate 1 21 along the central axis of the disk body 1, that is, the notch 3 on the mounting plate 1 21 and the mounting plate 22 is located on both sides of the length direction of the mounting plate 2.

[0041] Reference Figure 1 and Figure 2 Each notch 3 has an arc-shaped edge on the side closest to the central axis of the mounting plate 2, which reduces stress concentration at the notch 3 and extends the service life of the mounting plate 2.

[0042] The implementation principle of a PCBA loading tray according to an embodiment of this application is as follows: During installation, the worker places mounting plate 1 21 and mounting plate 22 alternately on the tray body 1. The second screw hole 24 in the overlapping area is exposed through the notch 3 on the opposite mounting plate 2. At the same time, multiple first screw holes 23 are in the non-overlapping area and are not blocked by the opposite mounting plate 2. The worker screws into the tray body 1 smoothly through the first screw hole 23 and the second screw hole 24, thereby realizing the smooth installation of the mounting plate 2 on the tray body 1 and increasing the loading capacity of the loading tray for the mounting plate.

[0043] Example 2

[0044] Reference Figure 2 and Figure 3 The difference between this embodiment and Embodiment 1 is that the end faces of the disc body 1 on both sides are detachably connected to positioning frames 5 via connecting components 4. Each positioning frame 5 has a positioning groove 51 that corresponds one-to-one with multiple mounting plates 2 on each end face. The positioning groove 51 has the same shape as the corresponding mounting plate 2.

[0045] When installing mounting plate 2, the worker places mounting plate 2 in positioning groove 51 for initial positioning.

[0046] Reference Figure 2 and Figure 3 The connecting component 4 includes a plurality of plug-in posts 41 fixedly connected to the bottom surface of the positioning frame 5. In this embodiment, the number of plug-in posts 41 on each positioning frame 5 is four. The four plug-in posts 41 located on the front side of the disk body 1 are respectively located at the four corners of the positioning frame 5, and the four plug-in posts 41 located on the back side of the disk body 1 are respectively located at the center of the four sides of the positioning frame 5.

[0047] Reference Figure 2 and Figure 3 The front and back sides of the disc body 1 are respectively provided with insertion slots 101 for engaging with four insertion posts 41. On the side of the insertion post 41 away from the positioning frame 5, a plurality of elastic strips 42 are evenly arranged circumferentially. In this embodiment, there are two elastic strips 42, which are respectively arranged on the radial sides of the insertion post 41. Each elastic strip 42 has a hook part 43 integrally formed at its end. When the two elastic strips 42 retract inward, the area of ​​the two hook parts 43 spliced ​​together is smaller than the cross-sectional area of ​​the insertion slot 101. When the two elastic strips 42 are in their natural state, the area of ​​the two hook parts 43 spliced ​​together is larger than the cross-sectional area of ​​the insertion slot 101.

[0048] Reference Figure 2 and Figure 3 Each hook part 43 is provided with a transition slope for easy insertion, and each positioning frame 5 is provided with a relief groove 52 for hooking onto the opposite hook part 43.

[0049] The implementation principle of Example 2 is as follows: When the positioning frame 5 is worn, deformed, or the indicator is blurred, a person first pinches the multiple hook parts 43 to make it detach from the disc body 1, then pushes the hook parts 43 to extend into the insertion groove 101, and finally pulls the positioning frame 5 outward to drive the insertion post 41 to detach from the insertion groove 101, thus realizing the disassembly of the damaged positioning frame 5.

[0050] When installing the positioning frame 5, the worker first aligns the plug post 41 with the plug groove 101, and then uses the guiding effect of the transition slope to insert the plug post 41 into the plug groove 101. At this time, the hook part 43 is squeezed by the inner wall of the plug groove 101, causing the elastic strip 42 to be in an inward contraction state. When the hook part 43 extends out of the plug groove 101, the elastic strip 42 opens outward by its own elasticity, so that the hook part 43 abuts against the outer surface of the disc body 1. In this way, the positioning frame 5 is installed. The setting of the connecting component 4 realizes the detachable installation of the positioning frame 5, so that the entire loading disc does not need to be replaced when the positioning frame 5 is damaged, which improves the convenience of worker maintenance and reduces maintenance costs.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
