[0025] By adopting the above technical solution, when conveying the retaining spring, the retaining spring is placed in the tooling at the first supporting platform 301, and the first clamping member 201 grabs the tooling equipped with the retaining spring and conveys it to the second supporting platform 302. The tooling equipped with the retaining spring is on standby at the second supporting platform 302, waiting for the subsequent action component to take away the tooling equipped with the retaining spring. The first supporting platform 301 can move close to the second clamping assembly, and the second clamping member 202 grabs the empty tooling from the second supporting platform 302 and moves toward the first supporting platform 301, and sends the empty tooling to the first supporting platform 301, waiting for the next retaining spring to be placed in the empty tooling. In this way, the first clamping member 201 is used to convey the tooling equipped with the retaining spring, and the second clamping member 202 is used to send the empty tooling back. The first clamping member 201 and the second clamping member 202 act simultaneously, which saves the time for loading the retaining spring, improves the loading efficiency, and shortens the loading cycle.

The first bearing platform 301 has a first bearing position 10, and the third bearing platform 303 has a third bearing position 11. When the line between the center of the first bearing position 10 and the center of the third bearing position 11 is parallel to the moving path of the first clamping member 201, the first bearing platform 301 is in a loading state. When the first bearing platform 301 is in the loading state, the distance between the center of the first bearing position 10 and the center of the third bearing position 11 is equal to the distance between the center of the clamping position of the No. 1 clamping jaw 2011 and the center of the clamping position of the No. 2 clamping jaw 2012. When loading, the No. 1 clamping jaw 2011 first grabs the first bearing position 1 0 is sent to the third carrying position 11, and then pre-pressed, and the next tool is placed on the first carrying position 10.

Movement. When conveying the retaining spring, the No. 1 driving member 601 drives the first clamping member 201 to slide horizontally to the first supporting platform 301 through the No. 2 driving member 602, and places the first clamping member 201 above the first supporting platform 301. At this time, the No. 2 driving member 602 is started to drive the first clamping member 201 to descend and clamp the tooling. The No. 2 driving member 602 is then started to lift the first clamping member 201, and then the No. 1 driving member 601 is started to move the first clamping member 201 to above the third supporting platform 303. The first clamping member 201 is moved by the first driving mechanism 6. The moving process reduces manual participation, making the movement of the first clamping member 201 efficient and convenient.

The cylinder body of the No. 3 driving member 701 is fixedly connected to the frame 1, and the cylinder body of the No. 4 driving member 702 is fixedly connected to the slider part of the No. 3 driving member 701. The second clamping member 202 is fixedly connected to the slider part of the No. 4 driving member 702. The No. 3 driving member 701 can drive the No. 4 driving member 702 to move in the horizontal direction, and the No. 4 driving member 702 can drive the second clamping member 202 to move in the vertical direction. When conveying the spring, the No. 3 driving member 701 drives the second clamping member 202 to slide horizontally through the No. 4 driving member 702. When the first platform 301 is moved to the bottom of the second clamping member 202, the No. 4 driving member 702 is started to lower the second clamping member 202 and place the empty tooling on the first platform 301. The second driving member 702 is started to lower the second clamping member 202 and place the empty tooling on the first platform 301. The second driving member 702 is started to lower the second clamping member 202 and place the empty tooling on the first platform 301. The second driving mechanism 7 is used to move the second clamping member 202. The movement process does not require manual intervention, making the movement of the second clamping member 202 efficient and convenient.

[0032] As another embodiment, the No. 1 driving member 601 includes a mounting member 6011, a servo motor 6012, a screw rod 6013, a slide rail 6014 and a slide seat 6015.

The cylinder body of the lifting cylinder 801 is fixedly connected to the frame 1, and the lifting plate 802 is fixedly connected to the piston rod of the lifting cylinder 801. The second load platform 302 is fixedly connected to the end of the lifting plate 802 facing away from the lifting cylinder 801. When the grabbing height of the next process is insufficient, the lifting cylinder 801 is started to lift the second load platform 302 to facilitate grabbing in the next process. At the same time, when the clamping mechanism 2 moves to the second load platform 302, the second load platform 302 is lowered to adapt to the height of the clamping mechanism 2, thereby reducing the probability of interference between the next process and the clamping mechanism 2.

[0034] Alternatively, the second carrying platform 302 is fixedly connected to the frame 1 with a constant height, and the lifting stroke of the clamping mechanism 2 is lengthened to reduce interference.

The No. 5 driving member 12 can drive the first supporting platform 301 to move. Using the cylinder to move the first supporting platform 301 is more efficient and convenient to coordinate with the rhythm of the No. 1 driving member 601 and the No. 3 driving member 701, thereby reducing the waiting time of the device.

[0036] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
