Problems solved by technology

However, in the existing testing mechanism, in order to facilitate the manual or manipulator to take and unload the material after the test is completed, the indenter driving mechanism uses two sets of cylinder driving mechanisms to realize the two actions of the test indenter's translation and downward pressure. Complex mechanism, high cost, low efficiency, cumbersome control

Embodiment

[0029] Example: Combine Figure 1~Figure 3 As shown, the specific implementation of the cam type press-down test mechanism of this liquid crystal screen PCB board connector provided by the present invention is described as follows:

[0030] It consists of machine base 1, test pressure head 2, downward pressure cylinder 3, first carrier plate 4, second carrier plate 5, cam block 6, rolling element 7, elastic reset member 8, horizontal guide rod 9, translation block 10, Vertical guide rail 11, vertical guide slider 12, horizontal guide rail 13, upper buffer 14, lower buffer 15 and horizontal guide slider 16 are jointly formed.

[0031] The machine base 1 adopts an upright form, and the downward pressure cylinder 3 is fixed on the front of the machine base 1. The ejector rod of the downward pressure cylinder 3 is connected with the first carrier plate 4 to drive the first carrier plate 4 to move in the vertical direction. The test pressure head 2 Fixed on the second carrier plat...

Abstract

The invention discloses a cam type downward pressing testing mechanism for a liquid crystal screen PCB (Printed Circuit Board) connector. The cam type downward pressing testing mechanism comprises an engine base and a testing pressure head and is characterized in also comprising a downward pressing cylinder, a first support plate and a second support plate, wherein the downward pressing cylinder is fixed on the engine base; the ejector pin of the downward pressing cylinder is connected with the first support plate for driving the first support plate to move along a vertical direction; the testing pressure head is fixed on the second support plate; the second support plate is movably connected below the first support plate through a translation guidance mechanism; meanwhile, a rolling body is pivoted to the second support plate; the engine base is fixedly provided with a cam block which is cooperated with the rolling body for driving the second support plate to carry out translation relative to the first support plate; and in addition, an elastic reset element used for the second support plate to carry out translation and reset is arranged in the translation guidance mechanism. The cam type downward pressing testing mechanism has a simple structure, and can finish the translation and downward pressing action of the testing pressure head by one set of action, so that a movement locus is reduced, working efficiency is improved, and manufacture cost is lowered.

Description

technical field [0001] The invention relates to a cam type press-down testing mechanism of a liquid crystal screen PCB board connector. Background technique [0002] After the LCD screen PCB board connector is produced, it needs to be tested, and it is powered on to detect whether it can light up the LCD screen. [0003] At present, the industry uses a special press-down test mechanism to test the connector of the LCD screen PCB board. This press-down test mechanism is usually composed of a test indenter with contacts and an indenter driving mechanism that drives the action of the test indenter. The test The indenter is connected to a power source through a wire. However, in the existing testing mechanism, in order to facilitate the manual or manipulator to take and unload the material after the test is completed, the indenter driving mechanism uses two sets of cylinder driving mechanisms to realize the two actions of the test indenter's translation and downward pressure. ...
