Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, and in particular to a novel LED light strip patch carrier. Background Art

[0002] At present, the PCB materials for LED light strips are divided into two delivery modes: continuous piece delivery and single piece delivery. The PCBs delivered in continuous pieces include the corresponding process edges, the board material consumption is large, and the cost is high. At the same time, the PCBs delivered in continuous pieces need to add a splitting station during the SMT production process, which undoubtedly increases labor costs. In addition, the splitting station is also prone to generate dust, affecting the quality of the final product. Therefore, the current PCB delivery is mainly delivered in single pieces.

[0003] Single-piece PCBs delivered in SMT production lack position limits, making precise alignment impossible for SMT solder paste printing and other production operations. The current solution is to design carriers for PCBs of varying sizes to provide position limits and assist in SMT production. However, specialized carriers for LED light strips lack universality, and the large number of incompatible carriers leads to significant resource waste and management difficulties. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a novel LED light strip chip carrier with strong versatility.

[0007] A pressure strip is detachably mounted on the main body, and a plurality of limiting strips are provided on the side of the pressure strip close to the base plate, and a sheet material limiting groove corresponding to the step limiting groove is formed between two adjacent limiting strips, and the sheet material limiting groove is arranged in a one-to-one correspondence with the step limiting groove.

[0008] In one embodiment, a plurality of the stepped limiting grooves are arranged at equal intervals on the end protrusion.

[0009] In one embodiment, side ridges are respectively provided on two opposite sides of the substrate.

[0010] In one embodiment, the central axes of the sub-limiting grooves in the same stepped limiting groove are collinearly arranged.

[0011] In one embodiment, the base plate is provided with an avoidance groove for avoiding the limiting strip.
