Description

Technical Field

[0001] The utility model relates to the technical field of functional circuit testing, in particular to a jig mechanism for vertically placing boards on an automated line. Background Technique

[0002] There are relatively deficiencies in the self-monitoring and self-detection within domestic enterprises in our country, which makes it difficult to detect product quality problems in a timely manner during the production process. Usually, by the time the third-party inspection agency finally discovers the problems, large-scale production has already been completed, resulting in serious waste of manpower, material resources, and financial resources. The root cause of this problem lies not only in the imperfect production quality supervision system within the enterprise. At the same time, it is also related to the current detection technology level in our country. In order to narrow this gap, our country needs to increase investment in scientific and technological research and development, improve the technical level, and at the same time strengthen the quality management system within the enterprise to ensure the improvement of product quality and production efficiency. This will help our country make more remarkable progress in the field of inspection and testing and better adapt to the competition in the global market. Currently, when testing PCB boards, basically a single-channel is used to burn the PCB circuit board, with a relatively long testing time and high labor costs, resulting in a low testing efficiency of the PCB circuit board, which in turn affects the production efficiency of the PCB circuit board. Moreover, it is not convenient to replace or adjust the PCB circuit board, making the adaptability of the PCB circuit board relatively low, with poor flexibility and few uses.

Two vertically upward detection seats 10 are provided at the top end of the base 1. Two rows of sensors 11 for detecting the arrival of the PCB are provided on the side of the detection seat 10 facing the PCB board.

[0023] Among them, a reinforcing pillar 12 is provided at the top of the base 1 between two opposite moving plates 5. A connection hole for the guiding link 4 to pass through is formed in the reinforcing pillar 12. Two reset springs 9 are provided between the two opposite moving plates 5. Installation grooves 13 matching the ends of the reset springs 9 are formed in both the moving plates 5 and the reinforcing pillar 12. A positioning post 14 is provided on the inner wall of the installation groove 13. The detection seat 10 and the reinforcing pillar 12 are connected by bolts. A limiting support plate 15 for limiting and supporting the PCB board is connected to the bottom end of the detection seat 10 by bolts. The reinforcing pillar 12 can improve the stability of the detection seat 10, also improve the stability of the guiding link 4, and further improve the stability of the movement of the moving plates 5, thus improving the clamping stability of the fixture 6 for the PCB circuit board, and facilitating the programming.

[0027] During operation, for the fixture 6 mechanism suitable for the vertical plate placement on the automated production line, when clamping the PCB board, the multiple mechanical grippers 7 on the clamping mechanism 2 are loosened. Under the action of the elastic potential energy of the reset spring 9, the two moving plates 5 move away from each other.
