A bending type board function test fixture and device

Abstract

The invention discloses a function testing fixture and device of a bending type board card, comprising: a clamping module and a carrier module; the clamping module is placed on the upper surface of the carrier module; the clamping module comprises a flip-up mould group and board seat; the shape of the upper surface of the board seat is consistent with the shape of the bending board; the flip module is provided with a needle block module, and one end is hinged with the board seat; the carrier module includes a carrier; the carrier A needle board is floatingly connected below, and a carrier board probe is arranged on the needle board; the formed device also includes a pressing plate module, a support module, an action control module, a vertical drive module, a horizontal drive module, and a bottom plate; the advantages of the present invention The balance pressing action is realized by the clamping module transfer, which simplifies the structure; the double-layer transfer signal structure can prevent the probe from being pulled; at the same time, the overall frame of the testing machine can be designed as a standard frame, which is convenient for different boards to be tested. Between upgrades, the tester standardized framework helps reduce design and maintenance costs.

Description

technical field [0001] The invention relates to the technical field of board card testing devices, in particular to a bending type board card function testing fixture and device. Background technique [0002] With the rapid development of electronic product technology and the increasing requirements for process efficiency and yield, the electronic industry has gradually begun to strengthen the development and optimization of product functional testing equipment while improving the process efficiency of electronic products. Among them, the demand for functional test (FCT) of electronic product motherboard is the most urgent. [0003] Common FCT testing machines are mainly used to test flat boards, while the research and development of FCT testing machines for curved boards is lagging behind. For the FCT testing machine for curved boards, the traditional structure is to install the needle board module on the platen module, and use multiple cylinders to drive the platen module...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the use of multiple push-down drive structures at different angles, the structure of this type of curved board testing machine is very complicated, which increases the design cost and maintenance cost;

[0005] 2. Due to the use of multiple push-down drive structures at different angles, it is difficult to realize that the probes of different push-down drive structures contact the board under test at the same time, causing local force synchronization, pulling the board under test, and damaging the board under test Card;

[0006] 3. Due to the use of multiple push-down drive structures at different angles, the overall structure will vary greatly due to different tested boards, which is not conducive to standardized structural design, and is not conducive to the reuse of old parts and modules. Group control cost

The above technical solution provides a middle board clamping structure. If it is applied to the bending board test, it can be used to clamp the unilateral structure of the bending side, but this does not solve the problem of signal transfer. At the same time, in the whole testing machine It is not convenient to place, nor is it convenient for the pressing device to press down, so further improvement is needed
