[0002] In the modern electronics manufacturing industry, the production scale of PCBA (Printed Circuit Board Assembly) is constantly expanding, and the requirements for production efficiency and quality are also increasing.
[0003] When PCBAs are packaged using SMT (Surface Mount Technology), they undergo a manufacturing process involving Deflux (flux removal), Baking, Plasma treatment, and UF (ultrasonic cleaning). Currently, various sizes of trays and fixtures are used for loading and unloading in these processes. These different sized material handling tools are difficult to adapt to the equipment in each production stage, lacking versatility and hindering automated, serial production. Switching between equipment in different production stages requires manual changing of different trays or fixtures, which not only increases production time and costs but also easily causes PCBA deformation, affecting product quality. Summary of the Invention
[0004] The purpose of this application is to provide a PCBA processing carrier that can solve the technical problems of existing PCBA trays or fixtures lacking versatility, failing to achieve serial automated production, and requiring manual switching of different trays or fixtures when switching between equipment in different production and processing stages. This not only increases production time and costs but also easily causes PCBA deformation, affecting product quality.
[0005] This application provides a PCBA processing carrier, including:
[0006] A hollow frame, wherein multiple placement areas are provided from top to bottom within the hollow frame;
[0007] A clamping tray, which is used to clamp PCBA and can be inserted into the placement area;
[0008] A limiting component is provided on the hollow frame to limit the clamping tray and prevent the clamping tray from falling off the hollow frame.
[0009] Furthermore, the hollow frame includes an upper frame and a lower frame arranged vertically, and a left frame and a right frame fixedly arranged between the upper frame and the lower frame. The inner side of the left frame has a plurality of first support protrusions from top to bottom, and the inner side of the right frame has a plurality of second support protrusions from top to bottom. The first support protrusions and the second support protrusions are arranged in parallel, and two adjacent first support protrusions and second support protrusions from top to bottom form the placement area.
[0010] Furthermore, the height of the clamping tray is equal to the distance between two adjacent first support protrusions.
[0011] Furthermore, the clamping tray includes a bracket and a cover plate. Multiple magnets are embedded around the cover plate, and the cover plate is attracted to the top of the bracket by the magnets. The PCBA can be placed between the bracket and the cover plate.
[0012] Furthermore, there are two limiting components, which are respectively located at one end of the left frame and the right frame, and the two limiting components are staggered.
[0013] Furthermore, the limiting assembly includes a rotating shaft, a connecting piece, a limiting rod, and a spring. The ends of the left frame and the right frame are provided with an upper hole and a lower hole. The lower end of the rotating shaft is inserted into the upper hole. The upper end of the rotating shaft and the upper end of the limiting rod are respectively fixedly connected to the bottom of the connecting piece. The lower end of the limiting rod is bent up and inserted into the lower hole. The spring is sleeved on the rotating shaft and located between the rotating shaft and the upper hole. Under the action of the spring, the lower end of the limiting rod abuts against the bottom of the left frame or the right frame. The upper frame and the lower frame are both provided with limiting grooves that are adapted to the limiting rod.
[0014] Furthermore, both the left frame and the right frame are provided with a storage groove for accommodating the limiting rod.
[0015] The beneficial effects of this utility model are:

[0032] like Figure 1 and Figure 5 As shown, this application provides a PCBA processing carrier, including a hollow frame 1, a clamping tray 3, and a limiting component 4. The hollow frame 1 has multiple placement areas 2 arranged from top to bottom. The clamping tray 3 is used to clamp PCBAs and can be inserted into the placement areas 2. The limiting component 4 is disposed on the hollow frame 1 to limit the clamping tray 3, preventing it from falling off. Different types and sizes of PCBAs can be clamped by the clamping tray 3 and then inserted into the placement areas 2 of the hollow frame 1. The limiting component 4 ensures the stability of the clamping tray 3 during use, preventing it from falling off and ensuring the continuity of the processing. When switching between equipment in different production processing stages, there is no need to manually switch between different trays or clamps, resulting in strong versatility, effectively shortening production time and reducing production costs. It also avoids PCBA deformation caused by frequent switching between different trays or clamps, ensuring product quality.
[0033] like Figure 1As shown, the hollow frame 1 includes an upper frame 11 and a lower frame 12 arranged vertically, and a left frame 13 and a right frame 14 fixedly arranged between the upper frame 11 and the lower frame 12. The inner side of the left frame 13 has multiple first support protrusions 131 from top to bottom, and the inner side of the right frame 14 has multiple second support protrusions 141 from top to bottom. The first support protrusions 131 and the second support protrusions 141 are arranged parallel to each other. Two adjacent first support protrusions 131 and second support protrusions 141 from top to bottom form a placement area 2. The structure of the hollow frame 1 is similar to a cuboid frame, and the various frames are... The interconnected structure provides a stable support for the entire frame. During PCBA processing, the carrier is affected by external forces such as handling and equipment vibration. The stable frame structure can ensure the shape and integrity of the carrier and prevent deformation or damage due to external forces, thereby ensuring the safety of the PCBA placed inside. Multiple first support protrusions 131 and second support protrusions 141 divide the internal space of the hollow frame 1 into multiple placement areas 2, realizing the layered utilization of space, improving space utilization, enabling the carrier to accommodate more PCBAs, and helping to improve production efficiency.
[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the height of the clamping tray 3 is equal to the distance between the two adjacent first support protrusions 131. The clamping tray 3 can be tightly inserted into the placement area 2, effectively preventing the clamping tray 3 from shaking up and down in the hollow frame 1 and improving the processing quality.
[0035] like Figure 5 As shown, the clamping tray 3 includes a bracket 31 and a cover plate 32. Multiple magnets 321 are embedded around the cover plate 32. The cover plate 32 is attracted to the top of the bracket 31 by the magnets 321. The PCBA can be placed between the bracket 31 and the cover plate 32, making the operation of placing and removing the PCBA very convenient. The operator only needs to gently remove or place the cover plate 32 to carry out the loading and unloading operation of the PCBA. There is no need to use complicated tools or perform cumbersome mechanical fixing operations. In the process of large-scale production, it can greatly improve production efficiency and reduce the loading and unloading time of each PCBA. PCBAs of different types and sizes can be placed in the bracket 31 and then clamped by the cover plate 32, which has strong versatility.
[0036] like Figure 1-3 As shown, there are two limiting components 4, which are respectively located at one end of the left frame 13 and the right frame 14. The two limiting components 4 are staggered and limit the clamping tray 3 placed in the placement area 2 to prevent it from falling out of the hollow frame 1.
[0037] like Figure 1-4As shown, the limiting assembly 4 includes a rotating shaft 41, a connecting piece 42, a limiting rod 43, and a spring 44. The ends of the left frame 13 and the right frame 14 are provided with an upper hole 5 and a lower hole 6. The lower end of the rotating shaft 41 is inserted into the upper hole 5. The upper ends of the rotating shaft 41 and the upper ends of the limiting rod 43 are respectively fixedly connected to the bottom of the connecting piece 42. The lower end of the limiting rod 43 is bent up and inserted into the lower hole 6. The spring 44 is sleeved on the rotating shaft 41 and located between the rotating shaft 41 and the upper hole 5. Under the force of the spring 44, the lower end of the limiting rod 43 abuts against the bottom of the left frame 13 or the right frame 14. Next, both the upper frame 11 and the lower frame 12 are provided with limiting grooves 7 that are adapted to the limiting rod 43. The setting of the spring 44 ensures that the limiting rod 43 always maintains the abutting pressure on the bottom of the frame, ensuring that even if the carrier is affected by external forces such as vibration and shaking during normal use, the limiting rod 43 will not easily leave its limiting position, thereby effectively preventing the clamping tray 3 from falling off the hollow frame 1. When the limiting rod 43 is in normal working condition, the limiting rod 43 and the limiting groove 7 cooperate with each other to limit the clamping tray 3 from both the front and rear directions.
[0038] like Figure 4 As shown, both the left frame 13 and the right frame 14 are provided with storage slots 8 for accommodating the limiting rod 43. The limiting rod 43 can be stored away when not in use, without taking up extra space around the vehicle. Specifically, in the initial state, the limiting rod 43 is located in the storage slot 8, and the lower end of the limiting rod 43 abuts against the bottom of the corresponding left frame 13 or right frame 14 under the action of the spring 44. When the limiting rod 43 needs to be in the working state, the connecting piece 42 is pressed down and bent. The limiting rod 43 is disengaged from the storage groove 8 and locked in the limiting groove 7, releasing the pressure on the connecting piece 42. Under the action of the spring 44, the lower end of the limiting rod 43 returns to its original position and abuts against the bottom of the corresponding left frame 13 or right frame 14. The lower end of the limiting rod 43 returns to the storage groove 8, locking the limiting rod 43. The clamping tray 3 inserted in the hollow frame 1 abuts against the limiting rod 43, effectively limiting the clamping tray 3.
[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
