As shown in fig. 3, an adsorption hole 7 is arranged at the bending part of the righting frame for upwards supporting the opening of the rubber ring of the condom 5. The vacuum pump 4 is communicated with the inside of the iron pipe 6 through a telescopic pipe 8, and the vacuum pump 4 is opened when the righting frame supports the rubber ring opening of the condom 5 to move upwards so as to generate downward suction to the rubber ring opening of the condom 5 through the suction holes 7, thereby ensuring that the rubber ring opening of the condom 5 smoothly falls to the bending part of the righting frame.
And two sides of the righting frame are vertically provided with a base plate 9. The two pressing mechanisms are respectively and rotatably arranged on the two base plates 9 and synchronously rotate in the process that the supporting rod 2 moves upwards so as to press the rubber ring opening of the condom 5 to the bending part of the righting frame. The method comprises the following specific steps:
the pushing mechanism comprises a rotating rod 10, a balancing weight 11, a top rod 12 and a pushing rod 13. One end of the rotating rod 10 is located above the bending part of the righting frame and at a position far away from one side of the condom 5, the other end of the rotating rod extends downwards towards the corresponding base plate 9 in an inclined mode, and the middle part of the rotating rod 10 is hinged to the base plate 9. The balancing weight 11 is fixed to the lower end of the rotating rod 10. The base plate 9 is provided with a sliding groove for the up-and-down movement of the ejector rod 12.

After the air claw 3 grabs the rubber ring opening of the condom 5, the supporting rod 2 drives the righting frame to move downwards towards the direction far away from the condom 5 so as to sleeve the grabbed condom 5 into the detection rod for electric detection.
The following describes a complete working process of the present invention:
firstly, the head of a seminal vesicle of a condom 5 is sucked into a negative pressure suction pipe 1 in a negative pressure mode, then an air cylinder driving a supporting rod 2 to move is started, an iron pipe 6 moves upwards to the position right below the negative pressure suction pipe 1 in the direction of the condom 5 under the driving of the air cylinder or a linear device along with the supporting rod 2, then the supporting rod 2 moves upwards for a small distance according to the actual situation under the continuous driving of the air cylinder or the linear device, so that the iron pipe 6 supports a rubber ring opening of the condom 5, and the rubber ring opening of the condom 5 is supported to the bending part of a righting frame by means of the self elasticity of the rubber ring opening of the condom 5 and the W-shaped iron pipe 6, so that the rubber ring opening of the condom 5 is positioned in the same horizontal plane to complete the righting of the condom 4. In addition, the condom 4 is righted, and the following actions of sucking down the opening of the rubber ring of the condom 5 and pressing down the opening of the rubber ring to the bending part of the righting frame are also carried out at the same time:
(1) the lower part of the opening of the rubber ring of the condom 5 is sucked to the bending part of the righting frame
When the supporting rod 2 moves upwards, the vacuum pump 4 is started, the inside of the iron pipe 6 is vacuumized through the telescopic pipe 8, the inside of the iron pipe 6 is vacuumized and then sucked downwards through the adsorption hole 7 to the rubber ring opening of the condom 5, and the adsorption hole 7 is arranged at the bending part of the righting frame, so that the rubber ring opening of the condom 5 can smoothly slide to the bending part of the righting frame under the action of the suction force.
(2) The opening of the rubber ring of the condom 5 is pressed down to the bending part of the righting frame
When the supporting rod 2 moves upwards, the supporting rod pushes the lower end of the rotating rod 10 upwards through the ejector rod 12, and the rotating rod 10 rotates by overcoming the gravity of the counter weight 11 through the ejector rod 12 along with the continuous upward movement of the supporting rod 2; after the rotating rod 10 rotates, the upper end of the rotating rod drives the lower end of the lower pressure rod 13 to press the rubber ring opening of the condom 5 to the bending part of the righting frame, and the rubber ring opening of the condom 5 can smoothly slide to the bending part of the righting frame under the action of the lower pressure. The lower ends of the lower pressure rods 13 in the two groups of the lower pressure mechanisms, namely the minimum distance between the two soft balls 15, are designed to correspond to the radial size of the opening of the condom ring, the radial size of the opening of the condom ring in the whole condom is the largest, and when the lower ends of the two lower pressure rods 13 move upwards, the distance between the lower ends of the two lower pressure rods is larger and larger, so that the two soft balls 15 cannot contact the side wall of the condom; similarly, when the lower ends of the two lower pressing rods 13 move downwards, the distance between the lower ends is smaller and smaller, but the distance is still larger than the radial size of the part outside the rubber ring opening on the condom, and the two soft balls 15 can not contact the side wall of the condom, so that the situation that the lower pressing mechanism only contacts the rubber ring opening of the condom in the up-and-down movement process is ensured, and the condom is damaged by the fact that the lower pressing mechanism contacts the side wall of the condom is prevented. On the other hand, even if the pressing mechanism can touch the condom, the soft ball 5 of the pressing mechanism touches the condom, and the soft ball 5 is soft and the condom has certain elasticity, so that the condom cannot be damaged even if the soft ball 5 touches the condom.
In conclusion, the actions of sucking and pressing the opening of the rubber ring of the condom 5 to the bending part of the righting frame are carried out while the condom 4 is righted, namely, the double actions of sucking and pressing the opening of the condom rubber ring by the vacuum pump 4 and pressing the opening of the condom rubber ring by the pressing mechanism are ensured, the opening of the condom rubber ring can effectively and reliably fall on the bending part of the righting frame, the opening of the condom rubber ring is positioned on the same horizontal plane, and therefore the smooth operation of grabbing the condom and performing electric detection is ensured.
After the rubber ring mouth of the condom 5 falls to the bending part of the righting frame, as shown in fig. 4, the pneumatic claw 3 stretches, advances to the position b from the position a, and returns to the position a after clamping the rubber ring mouth of the condom 5. And then the supporting rod 2 drives the righting frame to move downwards together under the driving of the cylinder or the linear device, and the negative pressure suction pipe 1 is moved away from the right lower part, so that the condom 5 is grabbed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
