According to the technical scheme provided by the invention, after the thimble springs with upward thimbles at the feeding station are picked up by the material taking part 21 and then conveyed to the turnover mechanism 3 of the material taking station, the turnover part 31 turns over the conveyed thimble springs so that the thimbles of the thimble springs face downwards, and then the thimble springs are subjected to angle adjustment by the adjusting mechanism 4, so that the thimbles can be adjusted to a proper position for subsequent assembly, the pick-up part 51 is used for adjusting the angle, and the thimble springs with downward thimbles are picked up and then conveyed to the assembly station, and the thimbles of the thimble springs are inserted into the jacks of products at the assembly station in a downward movable stroke, so that the assembly equipment 100 capable of accurately and efficiently realizing automatic assembly of the Pin springs and the products is provided, and the problems of low manual operation efficiency, poor quality and the like in the feeding and assembly process of the Pin springs are solved.

The thimble spring is of an integrally formed structure, the head end of the thimble spring is in the form of a spring ring, the tail end of the thimble spring is a thimble extending from the tail end of the spring ring, the thimble is arranged in parallel with the axis of the spring ring, and the thimble spring is eccentrically arranged with the center of the section of the spring ring. When the thimble is inserted, the thimble needs to be adjusted to a preset position, so that the accurate matching between the thimble spring and the product Rubber can be ensured.

Specifically, in order to be convenient for centre gripping thimble spring, can make the thimble spring just can be initially positioned when being overturned, in this embodiment, upset portion 31 is including keeping away from each other and being close to two arm clamps 311 that set up, one side that two arm clamps 311 are close to each other all is provided with the arc concave surface, two arc concave surfaces enclose and form the clamping space that is used for the centre gripping spring coil. It can be understood that the two arc concave surfaces are matched with the spring ring of the thimble spring, when the turnover part 31 picks up the spring ring, the spring ring can be limited in the clamping space so as to be positioned, so that after the turnover part 31 turns 180 degrees, the thimble spring can be positioned in a set position in the x direction and the y direction on the plane where the thimble spring is positioned, and after the different positions of the thimble spring are prevented from being turned, the position of the thimble spring cannot be determined.

Further, in the present embodiment, the adjusting mechanism 4 includes an adjusting portion 41, where the adjusting portion 41 includes a base 411, and a positioning pin 412 protruding from the base 411 and extending upward, and an annular end surface 4111 is formed on the top of the base 411, the positioning pin 412 is used for passing through a spring coil, and the annular end surface 4111 is used for supporting a thimble; the adjusting part 41 is rotatably disposed around the axis thereof to drive the thimble spring to rotate.

It will be appreciated that, because the positioning pin 412 is fixed in position and fixed in the x-direction and y-direction, in order to ensure that the spring ring can be accurately sleeved on the positioning pin 412 when the two clamping arms 311 are released after the turnover part 31 turns over, it is also necessary to ensure that the turnover part 31 clamps the spring ring each time and simultaneously can primarily adjust the position of the spring ring.

It will be appreciated that, in order to enable the spring ring to be sleeved on the circumferential side of the positioning pin 412, the positioning pin 412 is in clearance fit with the spring ring, and because the thimble and the spring ring are eccentrically arranged, when the spring ring is sleeved on the positioning pin 412, the thimble is located at the side of the positioning pin 412, and the thimble spring is supported on the annular end surface 4111 through the thimble. In this way, when the adjusting portion 41 is rotated, a friction force exists between the thimble spring and the annular end surface 4111, and the thimble spring rotates by an angle along with the rotation of the adjusting portion 41, so as to adjust the angle of the thimble, so that the thimble can be adjusted to the clamping angle required by the pick-up portion 51.

Further, in order to facilitate better adjusting the thimble to a desired angle, in this embodiment, the adjusting mechanism 4 further includes a stop portion 42, where when the adjusting portion 41 drives the thimble spring to rotate, the stop portion 42 is used to stop the thimble, so that the thimble spring can be limited at a preset position. Because the positioning pin 412 is in clearance fit with the spring ring, when the spring ring is subjected to an external force along the circumferential direction of the spring ring, the spring ring has a degree of freedom of rotating relative to the positioning pin 412, so when the adjusting part 41 drives the thimble spring to rotate, the thimble is limited after the thimble abuts against the stop part 42, and then when the adjusting part 41 rotates further, the thimble spring overcomes a friction force with the annular end surface 4111 and slides relative to the annular end surface 4111. Therefore, when the spring ring is driven to rotate only through the stop part 42, the ejector pin is stopped, the position of the ejector pin spring is established according to the position of the stop part 42, the initial position of the ejector pin is not required to be identified and detected through other position detection devices (such as a position sensor and the like), the displacement amount required to be adjusted by the adjusting part 41 is not required to be calculated through a control device, and the device is simple in structure and accurate in positioning.

Because the clamping jaw 511 clamps the spring coil when clamping the spring coil, the two first clamping arm segments 5111 clamp the spring coil, the two second clamping arm segments 5112 clamp the thimble, and the part connected between the thimble and the spring coil is located at the lower end of the stop block 512, that is, the upper end of the thimble abuts against the stop block 512. When the thimble spring is inserted, the thimble will have an upward moving trend when being inserted downwards due to the elastic force of the spring ring, and the stop block 512 abuts against the upper end of the thimble, so that the spring and the Rubber are effectively prevented from being ejected out after the spring is assembled.

Further, in order to facilitate the clamping of the ejector pins by the clamping jaw 511, a more stable clamping effect is achieved, concave-convex structures 51121 are provided on the opposite side portions of the two second clamping arm sections 5112, and the concave-convex structures 51121 can be provided as V-shaped grooves, so that the friction of the ejector pins is increased by the V-shaped groove structures, and the horizontal upward swing is avoided.
