[0013] Figure 3 yes Figure 1 Schematic diagram of the enlarged structure at N. DETAILED DESCRIPTION

[0014] The utility model is described in detail below in conjunction with specific implementation methods:

[0015] like Figures 1 to 3 The photoelectric coupler performance quick detection device shown in the figure includes a bearing seat 1, a suspension rod 2, a support plate 3, a quick clamp 4, a guide sleeve 5, a guide shaft 6, a spring 7, a connecting rod 71, an L-shaped carrier 8 and a pressure plate 9. The four suspension rods 2 are fixedly installed at the four corners of the bearing seat 1, the support plate 3 is fixedly sleeved and installed on the four suspension rods 2, the quick clamp 4 is fixedly installed on the support plate 3, the guide sleeve 5 is fixedly installed on the bearing seat 1, the pressure rod 41 and the guide shaft 6 of the quick clamp 4 are slidably installed in the guide sleeve 5, the upper end of the connecting rod 71 is screwed and installed in the pressure rod 41, the lower part of the connecting rod 71 is set as a T-shaped structure, the top of the guide shaft 6 is set as a T-shaped slot matching the bottom of the connecting rod 71, and the The lower part of the connecting rod 71 is clamped and installed in the T-shaped groove at the top of the guide shaft 6, and the spring 7 is sleeved and installed on the connecting rod 71. The upper and lower ends of the spring 7 act on the pressure rod 41 and the guide shaft 6 respectively. The pressure plate 9 is fixedly connected to the L-shaped platform 8 by the first bolt 90. A positioning area 81 is formed between the pressure plate 9 and the L-shaped platform 8. The pressure plate 9 is fixedly connected to the bottom of the guide shaft 6. An adjusting sleeve is rotatably installed at the lower part of the pressure rod 41. The upper end of the connecting rod 71 is screwed and installed in the adjusting sleeve. The upper end of the spring 7 acts on the adjusting sleeve. By rotating the adjusting sleeve, the stroke of the guide shaft 6 can be adjusted, that is, the downward movement stroke of the optocoupler 10 in the positioning area 81 is changed to avoid extrusion damage.

[0016] The outer end of the positioning area 81 is configured as a wide-mouth structure, that is, the outer top surface of the L-shaped carrier 8 and the outer bottom surface of the pressure plate 9 are configured as an angled structure, so that the photoelectric coupler 10 can easily enter the positioning area 81.

[0017] Four ball elastic pins 80 are arranged in a rectangular shape on the L-shaped carrier 8. When the photoelectric coupler 10 enters the positioning area 81, the photoelectric coupler 10 presses the ball elastic pin 80 downward. The rotation of the ball can reduce scratches on the bottom surface of the photoelectric coupler 10. After the photoelectric coupler 10 is placed in place, the ball elastic pin 80 bounces upward, pushing the top surface of the photoelectric coupler 10 to contact the pressure plate 9. Under the upward pressure of the ball elastic pin 80, the photoelectric coupler 10 can be prevented from moving after positioning.

[0018] The L-shaped carrier 8 is threadedly installed with a limit bolt 82. Rotating the limit bolt 81 can limit the extreme position of the photoelectric coupler 10 moving into the positioning area 81. When the photoelectric coupler 10 contacts the limit bolt 81, the positioning of the photoelectric coupler 10 is completed. It has the advantages of fast positioning speed and accurate positioning, and can meet the positioning requirements of photoelectric couplers 10 of different lengths.

[0019] A rubber pad 91 is fixedly attached to the bottom surface of the pressing plate 9 , and the thickness of the rubber pad 91 is set to 1-2 mm to prevent the pressing plate 9 from causing wear and scratches on the surface of the photoelectric coupler 10 .

[0020] According to the length and height of the photoelectric coupler 10, the position of the limit bolt 81 and the installation height of the pressure plate 9 are adjusted respectively to realize the rapid positioning of the photoelectric coupler 10 in the left and right directions. At the same time, the photoelectric coupler 10 can be pressed and fitted on the pressure plate 9 under the elastic force of the ball elastic pin 80. At the same time, the adjustment sleeve is rotated to adjust the downward movement stroke of the guide shaft 6 and the elastic force of the spring 7 to avoid extrusion damage to the photoelectric coupler 10. At the same time, under the elastic force of the spring 7, the pins of the photoelectric coupler 10 can be pressed and contacted with the contacts of the matching test circuit board. After the photoelectric coupler 10 is placed in the positioning area 81, the quick clamp 4 is pressed down to move its pressure rod 41 downward, so that the pins of the photoelectric coupler 10 are pressed and contacted with the contacts of the matching test circuit board, and then the detection operation can be carried out.
