Description

Technical Field

[0001] The utility model relates to the technical field of PCB carriers, in particular to a carrier for PCB board printing through the furnace. Background Technique

[0002] The PCB circuit board, also known as the printed circuit board, is a provider of electrical connections for electronic components. Its development has a history of more than one hundred years. Its design is mainly layout design. The main advantages of using the circuit board are to greatly reduce wiring and assembly errors, and improve the automation level and production labor rate.

[0003] When performing SMT patch through the furnace on a PCB board without a board edge structure, it is difficult to position the PCB board. To solve this problem, usually a patch through-furnace carrier is used to carry the PCB board for patch through-furnace. By placing the PCB board on the placement position provided on the carrier, and then using a positioning pin and tape to attach to one corner or one side of the placement position to ensure that the printing does not shift. However, attaching the tape will cause the board to be unable to cooperate with the board-taking carrier after the furnace, and the tape needs to be torn off on the track before taking the board; secondly, during the production process, there is no good positioning for the bare PCB board, which affects the printing effect. Content of the Utility Model

[0004] The purpose of the utility model is to provide a carrier for PCB board printing through the furnace to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A carrier for PCB board printing through the furnace, including vertical plates and a base.

An adjustment chamber is arranged on the side of the positioning groove, and a pull rod is arranged inside the adjustment chamber. One end of the pull rod is fixed with a push block, and the push block is clamped with the positioning post. A spring is connected between the side of the push block and one end of the inner wall of the adjustment chamber. A first relief groove is arranged on the side of the adjustment chamber, and a pull block is arranged at one end of the first relief groove, and the pull block is fixedly connected with the other end of the pull rod.

[0006] Preferably, a carrier plate is arranged at the upper end of the positioning post, and limiting grooves are arranged at both ends of the carrier plate.

[0007] Preferably, limiting blocks are arranged on the inner wall of the vertical plate corresponding to the limiting grooves, and the limiting blocks are fixedly connected with the vertical plate.

[0008] Preferably, an upper cover is arranged on the upper part of the carrier plate, and pressing strips are arranged at both ends of the upper end of the upper cover.

[0009] Preferably, guide posts are arranged at the front end and the rear end of the upper cover, and magnetic blocks II are arranged at the lower ends of the guide posts.

[0011] Preferably, a first magnetic block is provided at the lower end of the inner wall of the second relief groove corresponding to the second magnetic block, and the first magnetic block is magnetically connected to the second magnetic block.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: it is convenient to ensure that the shaking amplitude of the PCB bare board placed in the carrier is reduced, and it is easy to improve the printing offset phenomenon;

[0013] (1) The pull block can be pulled towards the middle in the first relief groove, driving the pull rod to move and the spring to compress, and then driving the push block to move to make way for the positioning post, so that the positioning post can be inserted into the positioning groove. After releasing the pull block, under the push of the spring, the push block is driven to reset through the pull rod, so that the push block is inserted into the positioning post. Thus, the position of the carrier plate is fixed well, avoiding shaking and facilitating disassembly and maintenance. The PCB bare board can be placed on the carrier plate, which is beneficial to improving the stability of the PCB bare board placed on the carrier plate. At the same time, the vertical plate limits the limit groove through the limit block, avoiding shaking of the PCB bare board, and facilitating ensuring that the shaking amplitude of the PCB bare board placed in the carrier is reduced.

[0014] (2) After adjusting the position of the PCB bare board, the upper cover can be covered on the upper part of the PCB bare board, and the pressing strip can fit and press the non-soldering area of the PCB bare board. When the guide post moves to the lowest position in the second relief groove, the first magnetic block and the second magnetic block touch and fit each other. Due to the mutual attraction of opposite magnetic poles, the upper cover is stably located at the upper end of the PCB bare board and limits the edge of the PCB bare board. Moreover, the second relief groove limits the guide post through the guide ring, which is beneficial to the stable lifting of the upper cover. BRIEF DESCRIPTION OF THE DRAWINGS
