The spring loading mechanism 5 includes a spring feed vibration plate 51, a spring handling assembly 52, a spring steering positioning assembly 53, a spring loading assembly 54, and a ram drive assembly 55.
The spring feed vibration plate 51 provides the spring element 15, the spring carrying assembly 52 carries the spring element 15 to the spring steering positioning assembly 53 for steering positioning, then carries the spring element 15 to the spring loading assembly 54, the spring loading assembly 54 loads the spring element 15 into the spring mounting position 16 in the jig assembly 22, and the ejector rod driving assembly 55 is matched with the assembly position in the loading process to realize accurate control of the assembly position.
Wherein, the spring assembly 54 is used for realizing the spring installation position 16 for installing the compression spring 16 in the jig assembly 22, and specifically comprises: a drive connection plate 5405, a spring jig plate 5409, and a push-push drive structure 5419 (specifically, a cylinder, a motor, or other driving members, etc.); the driving connection plate 5405 and the spring fixture plate 5409 are arranged in parallel at intervals up and down and are connected in a relative motion. Two groups of spring channels which are symmetrically arranged left and right are arranged on the spring jig plate 5409; each set of spring channels includes a transverse spring channel 5416 and a longitudinal spring channel 5417, with a spring slot 5418 disposed within the transverse spring channel 5416 and with one side end of the transverse spring channel 5416 communicating with the top end of the longitudinal spring channel 5417.

It will be appreciated that since the embodiment of the invention is described by way of example only with respect to the product 1 shown in fig. 2, the product 1 requires the assembly of two spring elements 15, and therefore, for efficiency, the spring assembly 54 is provided with two sets of spring channels to achieve automatic assembly of the two spring elements 15 simultaneously. In fact, matching to the current product can be achieved by simple channel number adjustment when the number of spring elements 15 to be assembled varies. The invention is not limited in this regard.

When the two positioning blocks 5308 are opened, the longitudinal finger clamping cylinder 525 can smoothly put the spring piece 15 into the longitudinal groove of the positioning support plate 5310; after the positioning block 5308 is clamped, the longitudinal position of the spring element 15 in the longitudinal groove of the supporting plate 5310 can be ensured to be consistent, and the space of the longitudinal groove after the positioning block 5308 is clamped is approximately equal to the initial length of the spring element 15, so that larger errors of the longitudinal position after the spring element 15 is discharged and turned can be avoided.
A ram drive assembly 55 comprising: the device comprises a bracket 551, a traversing cylinder 552, an ejector rod cylinder 553 and a pushing block 554; the pushing block 554 is mounted on the bracket 551 through the traversing cylinder 552 and the ejector rod cylinder 553, and can move to the side of the product 1 in the jig assembly 22 under the driving of the traversing cylinder 552 and the ejector rod cylinder 553 until the left slider 13 or the right slider 14 of the product 1 moves to a specified position.
The detailed workflow of the spring loading mechanism 5 is as follows:
1) The spring member 15 is conveyed to the right and left straight vibrating channels 513 and 514 through circular vibrating rail screening orientation, then the longitudinal finger clamping cylinder 525 is moved to the discharge port of the right straight vibrating channel 514 through the traversing cylinder 522 and the lifting cylinder 524, and the synchronous, mirror-image arranged spring handling assembly 52 moves the other longitudinal finger clamping cylinder 525 to the discharge port of the left straight vibrating channel 513 while simultaneously picking and placing the two longitudinal spring members 15 onto the positioning support plate 5310 of the spring steering positioning assembly 53.
