Examples

As shown in fig. 1 to 6, the optocoupler support turnover plate comprises a rectangular plate 10 and a positioning component 20.

Specifically, rectangular plate 10 has two parallel main air ducts 11 along length direction processing, main air duct 11 all links to each other with the aspirator pump, rectangular plate 10 top surface corresponds every main air duct 11 and has respectively processed at least one counter bore 12, the coaxial processing in counter bore 12 bottom has guiding hole 13 and exhaust hole 14, guiding hole 13 is coaxial with counter bore 12, and run through rectangular plate 10, exhaust hole 14 and main air duct 11 intercommunication, a plurality of suction holes 15 of rectangular plate 10 bottom surface processing, suction hole 15 all communicates with main air duct 11, counter bore 12 top is equipped with sealed lid 16, for reinforcing sealed effect, prevent the air leakage in the counter bore 12, be equipped with sealing washer 17 between sealed lid 16 and the rectangular plate 10, rectangular plate 10 corresponds the mounted position processing of sealing washer 17 and has the annular groove, sealing washer 17 inlays and locates in the annular groove.

Specifically, the positioning component 20 includes a piston column 21 and a positioning pin 22, the piston column 21 is slidably disposed in the counterbore 12, the positioning pin 22 passes through the guide hole 13, the length of the positioning pin 22 is greater than the depth of the guide hole 13, and the positioning pin 13 protrudes out of the bottom surface of the rectangular plate 10 when the optical coupler bracket is stacked and is inserted into a process hole a of the optical coupler bracket shown in fig. 7 to position the optical coupler bracket. The piston column 21 and the positioning pin 22 are integrally formed, and are formed by machining the same bar stock. The main air passage 11, the exhaust hole 14 and the air suction hole 15 are all round holes, and the diameter of the main air passage 11 is larger than the diameters of the exhaust hole 14 and the air suction hole 15.

More specifically, a layer of oil film is coated between the piston post 21 and the counterbore 12, the upper and lower chambers of the piston post 21 are isolated by the oil film, when the optical coupler bracket is sucked, the air pump sucks the lower part of the piston post 21 into a negative pressure or even a vacuum state through the main air duct 11 and the exhaust hole 14, the chamber above the piston post 21 is also formed with a negative pressure due to the downward movement of the piston post 21, but the negative pressure of the upper chamber is higher than that of the lower chamber, the oil film can prevent the upper chamber from being decompressed between the piston post 21 and the side wall of the counterbore 12, the negative pressure of the upper chamber is characterized in that when the optical coupler bracket on the rectangular plate 10 is overlapped with the fixed lower optical coupler bracket, the air pump stops working, the pressure between the main air duct 11 and the communicated pipelines is gradually increased, and the piston post 21 drives the positioning pin 22 to move upwards under the negative pressure of the upper chamber, so that the positioning pin 22 is smoothly separated from the optocoupler support. Therefore, to ensure the sealing between the piston post 21 and the counterbore 12, the tolerance level of the piston post 21 and the counterbore 12 is higher than IT 6. It should be noted that when installing the piston post 21, the piston post 21 is pressed into the bottom of the counterbore 12, and the seal cap 16 is installed to seal the counterbore 12.

Preferably, in order to prevent the positioning pin 22 from being unable to smoothly separate from the optocoupler support due to insufficient negative pressure above the piston column 21, a pressure spring is additionally arranged between the bottom surface of the piston column 21 and the bottom surface of the counter bore 12, the pressure spring is sleeved on the positioning pin 22, and when the air suction pump stops air suction, the positioning pin 22 can be more quickly retracted depending on the elastic force of the pressure spring. However, the compressive resistance of the pressure spring is smaller than the negative pressure formed when the air pump pumps air, so that the pressure spring can be compressed when the optocoupler support is sucked, and the positioning pin 22 extends out.

More specifically, as the pin that the opto-coupler support is used for installing the chip is used for the broken line frame C position shown in fig. 7, this part can be higher than the base plate of opto-coupler support usually, for preventing to cause the pin to warp among the closed assembly process, rectangular plate 10 bottom surface corresponds broken line frame C position and all processes rectangular groove 101 for dodge the pin. Every two air suction holes 15 are in a group and distributed along the axis of the main air duct 11, and the air suction holes 15 are arranged at the combination position on the optical coupler bracket, as shown in the range of a dotted line frame a and a dotted line frame b shown in fig. 7, because the structure of the optical coupler bracket is in array layout with regular distance, the air suction holes 15 are also arranged in array along the main air duct 11.

Preferably, because main air duct 11 length dimension is great, and the diameter is little moreover, for the processing of main air duct 11, consequently from the both ends processing main air duct 11 of rectangular plate 10, make main air duct 11 link up the both ends of rectangular plate 10, one end adopts end cap 18 to seal, and the trachea joint 19 is installed to the other end, utilizes trachea joint 19 to link to each other with the aspiration pump, and trachea joint 19 is for inserting the structure soon, is convenient for install and change the trachea.

Preferably, in order to further increase the positioning precision of the optocoupler support, four counter bores 12 are provided, two counter bores are provided for each main air passage 11, the four counter bores 12 are distributed in a rectangular shape, and the counter bores 12 are provided with positioning components 20.

Preferably, the piston post 21 is formed with a blind hole 211 at the top thereof to reduce the overall weight of the positioning member 20, thereby allowing the positioning pin 22 to move more flexibly.

The specific implementation process comprises the following steps: the optocoupler support turnover plate is arranged on a rotating device, and a hose connector 19 is connected with an air suction pump through a hose air pipe to perform air suction; then the optical coupler bracket is arranged in an optical coupler bracket in an active grabbing or other device placing mode, negative pressure is formed in the main air passage 11 and a pipeline connected with the main air passage 11 through an air pump, the rectangular plate 10 is contacted with the optical coupler bracket through the bottom surface, then the air suction hole 15 acts on the surface of the whole part of the optical coupler bracket to firmly suck the optical coupler bracket, and at the moment, because the negative pressure at the bottom of the piston column 21 is larger than the negative pressure at the top, the positioning pin 22 extends out, and the optical coupler bracket is inserted into the technical hole a of the optical coupler bracket to complete the fixation; then rotate the returning face plate through rotary device, make the opto-coupler support on the rectangular plate 10 align with the fixed opto-coupler support in below, after the opto-coupler support on the rectangular plate 10 overlaps with fixed lower piece opto-coupler support, the aspiration pump stop work, the pressure between main trachea 11 and each pipeline of intercommunication increases gradually, and piston post 21 will drive locating pin 22 to shift up under the negative pressure effect of cavity in the top this moment, makes locating pin 22 break away from the opto-coupler support smoothly.

The foregoing is only a preferred embodiment of the invention and is not intended to be the only or limiting embodiment of the invention. It should be understood by those skilled in the art that various changes and equivalent substitutions made herein may be made without departing from the scope of the invention as defined by the appended claims.
