Description

Technical Field

[0001] The present invention relates to the technical field of PCB board fixing carriers, and in particular to a split type PCB board fixing carrier. Background Art

[0002] Based on the PCB board or PCBA, the further processing post series process flow mainly involves brushing solder paste, patch, reflow soldering, dispensing glue, wave soldering and other work. Before these steps are carried out, the PCB board must be fixed in advance to facilitate the brushing of solder paste, patch, reflow soldering, dispensing glue, wave soldering and other operations on the PCB board.

[0003] The existing vehicles are all special vehicles designed and manufactured one-to-one for specific products. The vehicles between different products are not universal. After the product is upgraded or modified, the vehicles can only be scrapped and cannot be recycled and reused, resulting in a waste of resources and high production costs. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a split PCB board fixing carrier, which solves the problem that the existing carriers are all special carriers designed and manufactured one-to-one for specific products, and the carriers between different products are not universal.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a split PCB board fixing carrier, comprising: an outer shell, a reserved groove is opened inside the outer shell, an inner core is arranged inside the outer shell; the outer wall of the inner core is arranged inside the reserved groove, a plurality of rotating shafts 1 are rotated inside the outer shell, and the outer wall of the rotating shaft 1 is fixed with a buckle 1, the lower surface of the buckle 1 is in contact with the upper surface of the inner core, and a plurality of loading slots are opened inside the inner core, and the loading slots are slotted or opened according to specific products.

[0006] Preferably, the inner core has a plurality of rotating shafts 2 rotating inside, and outer walls of the rotating shafts 2 are fixed with buckles 2, and the PCB board is fixed and limited by rotating the buckles 2.

[0007] Preferably, the outer wall of the inner core is designed in a reverse two-step stepped manner, which cooperates with the inner wall of the outer shell through a step-fitting shape, thereby ensuring the stable position of the inner core inside the outer shell and ensuring the sealing of the two.

[0008] Preferably, the reverse two-step stepped design is a step-fitting shape, which can be accurately matched according to the actual sizes of the inner core and the outer shell, thereby improving the stability and accuracy of the fixation and ensuring that the inner core can be more conveniently fixed and disassembled during the disassembly and assembly process.

[0009] Working principle: The outer shell provides structural support for the entire carrier, and the reserved groove inside it provides space for the installation of the inner core. The inner core cooperates closely with the reserved groove through its outer wall to ensure its stability: the internal loading groove of the inner core is designed according to the product object and fits the opening or slot of the product object, so that it can be stably placed: Buckle 1 and buckle 2 are respectively fixed on shaft 1 and shaft 2, and further limit the PCB board through rotation to ensure that no displacement occurs during operation.

[0010] The present invention provides a split PCB board fixing carrier, which has the following beneficial effects:

[0011] The present invention achieves the convenience of disassembly and assembly of the carrier through the cooperation between the outer shell, the inner core and the buckle, adapts to different products, solves the problem of the specificity of the carrier, recycles resources for reuse, and directly reduces the production cost of the enterprise.

[0017] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Please see attached Figure 1 - Attachment Figure 3 The embodiment of the present invention provides a split PCB board fixing carrier, including: an outer shell 1, a reserved groove 2 is opened inside the outer shell 1, an inner core 3 is arranged inside the outer shell 1; the outer wall of the inner core 3 is arranged inside the reserved groove 2, a plurality of rotating shafts 5 are rotated inside the outer shell 1, and the outer wall of the rotating shaft 5 is fixed with a buckle 6, the lower surface of the buckle 6 is in contact with the upper surface of the inner core 3, and a plurality of loading slots 4 are opened inside the inner core 3, and the loading slots 4 are slotted or opened according to specific products.

[0019] Specifically, the outer jacket 1 has a reserved groove 2 inside, and an inner core 3 is arranged inside the outer jacket 1. The ingeniously designed structure makes the carrier have good stability and compatibility when fixing the PCB board; the outer wall of the inner core 3 is closely matched with the inner wall of the reserved groove 2, so that the whole system can effectively resist the influence of external force when working; there are multiple rotating shafts 5 rotating inside the outer jacket 1, and the outer walls of these rotating shafts 5 are fixed with buckles 6, and the buckles 6 are fitted with the upper surface of the inner core 3 through the lower surface, so as to achieve a firm fixation of the inner core 3 and facilitate disassembly when needed; multiple loading slots 4 are opened inside the inner core 3, which are specially used to accommodate PCB boards of different sizes, providing good adaptability and meeting diverse application needs. The design of the carrier makes the assembly process more efficient and reduces resource waste. At the same time, it improves the overall quality of the product, avoids the performance degradation caused by heat accumulation, and thus prolongs the service life of the equipment. The design of the inner core 3 carrier is designed and processed according to the hollowed-out area reserved by the outer jacket 1 carrier and the needs of specific PCB products.

[0020] Please see attached Figure 3 - Attachment Figure 4 The inner core 3 has multiple rotating shafts 27 for internal rotation, and the outer walls of the rotating shafts 27 are fixed with buckles 28. The PCB board is fixed and limited by rotating the buckles 28. The outer wall of the inner core 3 is a reverse two-stage stepped design, which is matched with the inner wall of the outer sleeve 1 through the step fit to ensure the stable position of the inner core 3 inside the outer sleeve 1 and the sealing of the two. The reverse two-stage stepped design is a step fit, which can be accurately matched according to the actual sizes of the inner core 3 and the outer sleeve 1, improve the stability and accuracy of the fixation, and ensure that the inner core 3 can be fixed and disassembled more conveniently during disassembly and assembly.

[0021] Specifically, the inner core 3 has multiple rotating shafts 27, and the outer wall of the rotating shaft 27 is fixed with a buckle 28. The PCB board can be accurately limited by rotating the buckle 28 to ensure that the position of the PCB board does not shift during assembly and use, thereby improving stability and precision. The outer wall of the inner core 3 adopts a reverse two-stage stepped design, which is precisely matched with the inner wall of the outer jacket 1 through the step fit, thereby ensuring the stable position of the inner core 3 inside the outer jacket 1, while improving the sealing, effectively preventing the influence of the external environment on the internal components, and enhancing the anti-interference ability of the structure. This reverse two-stage stepped design not only ensures the precise fit between the inner core 3 and the outer jacket 1, but also improves the assembly precision, making the inner core 3 easier and more convenient during disassembly and assembly, and avoiding installation difficulties or damage caused by dimensional errors.
