[0020] This solution aims to solve the problem that traditional relays usually have three sets of armatures, each set of armatures has different functions, shapes, and contact press-fitting positions. Therefore, during the production process, it is often necessary to configure multiple press-fitting equipment to press-fit armatures of different shapes for relays of different specifications, which is costly. If a single machine is used for press-fitting, it is necessary to repeatedly position the armature according to its shape, which affects production efficiency.

[0021] In this embodiment: Reference Figure 1-Figure 3 as well as Figure 6 As shown, a preferred embodiment of the present invention is provided.

[0022] The relay armature automatic press-fitting device of this embodiment comprises: A press-fitting platform 1 is provided with a positioning member 3, wherein the positioning member 3 comprises: a press-fitting plate 33, one end of which is a horizontal portion, and the other end of which is an inclined portion, wherein the angle between the inclined portion and the horizontal portion is 45°; The guide plate 34 can slide along the X direction and the Y direction, and can also rotate along the Z direction, and slide back and forth on the horizontal part and the inclined part of the pressing plate 33; Three groups of guide grooves 341 are equidistantly distributed along the X direction of the guide plate 34 to facilitate positioning. The ends of the guide grooves 341 are provided with adaptively sliding pads 344 to meet the positioning requirements of armatures 7 of different shapes; The feeding rail 4, whose end extends to the upper side of the pad 344 of the inclined part of the pressing plate 33, comprises: a positioning piece 41, on which a positioning groove 42 is opened, corresponding to the coordinates of the contact piece 8 of different specifications, so as to avoid the displacement of the pressing position of the contact piece 8 and the armature 7; a paddle 43, which is hinged to the side wall of the feeding rail 4 away from the positioning groove 42 through a spring shaft, and driven by an electromagnetic element to perform a 0°-60° fan-shaped expansion movement around the axis, so as to guide the contact piece 8 to fall into the preset position of the armature 7 on the pad 344; The press-fitting telescopic machine 5 is inclined and installed at the end of the inclined part of the positioning member 3. The movement direction of its telescopic part is parallel to the inclined part of the press-fitting plate 33. A press head is provided at the end of the telescopic part for press-fitting the contact piece 8 onto the armature 7 of the spacer 344.

[0023] Among them, the positioning member 3 further includes a slide table 31, which is slidably arranged on the press-fitting platform 1 along the Y direction. The guide plate 34 slides along the X direction on the slide table 31. A slide frame 32 is slidably installed on the slide table 31 along the X-axis direction. The slide frame 32 is arranged in a "冂" shape. The guide plate 34 is rotationally connected to the ends of the vertical parts on both sides of the slide frame 32. The guide plate 34 completes the functions of sliding in the Y direction and rotating in the Z direction through the slide frame 32.

[0024] Furthermore, the device further includes a vibrating hopper 2, which is docked with the inlet of the guide groove 341 when the guide plate 34 is in a horizontal state for conveying the armature 7 into the guide groove 341. The armature 7 slides along the guide groove 341 and is limited by the spacer 344. Between the vibrating hopper 2 and the positioning member 3, the press-fitting platform 1 is provided with guide rails 21 and feeding rails 22 that are staggeredly and parallelly distributed. One side of the end of the guide rail 21 is installed with a stop telescopic machine 24. The telescopic part of the stop telescopic machine 24 is used to stop the armature 7 and transfer it onto the feeding rail 22, so that the armatures 7 can enter the guide groove 341 of the guide plate 34 one by one, avoiding mutual interference.

[0025] Above the feeding rail 22 close to the guide rail 21, a feeding telescopic machine 25 is installed. The telescopic part of the feeding telescopic machine 25 is installed with a push rod 26 that is consistent with the conveying direction of the feeding rail 22. The length of the push rod 26 is the same as that of the feeding rail 22. Through the push rod 26, the armature 7 transferred onto the feeding rail 22 can be pushed into the guide groove 341 of the guide plate 34; It should be noted that a recognition sensor 23 is also installed below the feeding rail 22 close to the guide rail 21. The recognition sensor 23 is one or more of a vision sensor or a photoelectric sensor, etc., for recognizing the edge projection of the armature 7 (according to the contour matching or dimension measurement mapping of the matching database), and realizing the recognition of the armature 7 in cooperation with the external PLC programming, so as to judge the specification of the armature 7, and allocate and introduce it into the corresponding guide groove 341 according to the specification of the armature 7, and drive the position of one group of paddles 43 to guide the contact piece 8 according to the specification of the armature 7.

[0026] In the appendix Figure 4 and the appendix Figure 5In the embodiment, the end bearing of the guide plate 34 is connected with a rotating rod 342, the cushion block 344 is threadedly connected through the rotating rod 342, the outer side of the end of the rotating rod 342 is sleeved with a driving gear 343, the inclined end of the pressing plate 33 is installed with an adjusting motor 35, the output shaft of the adjusting motor 35 is sleeved with a driving gear meshing with the driving gear 343, when the guide plate 34 is tilted and slid to the pressing position through the inclined portion of the pressing plate 33, the driving gear 343 at the end of the rotating rod 342 will extend into the adjusting motor 35 at the end of the pressing plate 33 The adjusting motor 35 drives the rotating rod 342 to rotate via the driving gear 343, thereby driving the pad 344 connected to its external thread to slide in the guide plate 34, so as to adjust the relative position of the pressing part of the armature 7 and the alignment piece 41 according to the different specifications of the armature 7, so that the contact piece 8 can correspond to the pressing position of the armature 7. When the armature 7 is pressed, the adjusting motor 35 drives the pad 344 to slide out of the guide plate 34, so that the armature 7 pressed on the pad 344 falls off and is collected, so that the pressing operation of the next armature 7 can be continued.

[0027] Among them, the side surface of the cushion block 344 close to the armature 7 is provided with an inclined surface matching the contour of the armature 7, so that after the armature 7 is tilted through the guide plate 34, the armature 7 slides through the guide groove 341 and directly fits on the inclined surface of the cushion block 344, completing the limit and realizing automatic physical positioning at the same time.

[0028] For further information, see Attachment Figure 6 As shown, a collecting belt 61 is provided on the end surface of the inclined portion of the press-fitting plate 33, and a collecting tray 6 is also provided at the end of the press-fitting platform 1 located at the collecting belt 61. When the armature 7 that has been press-fitted on the cushion block 344 falls off, it will be directly received by the collecting belt 61 and then pushed into the collecting tray 6 for collection; Finally, the telescopic part of the press-fitting telescopic machine 5 moves vertically along the inclined part of the press-fitting plate 33, and the movement trajectory of the press head is consistent with the normal direction of the press-fitting surface of the contact piece 8, thereby eliminating the stress concentration caused by the angle deviation and pressing the contact piece 8 into the press-fitting position of the armature 7; Among them, the pressure head is equipped with a pressure sensor for pressure signal collection and feedback to improve the pressing effect.

[0029] In the present embodiment, during the shape transformation process of the guide plate 34, the guide plate 34 can be rotated around the Z axis to a horizontal state, the slide 31 moves along the Y direction to the horizontal end of the guide plate 34 to receive the material, and the guide plate 34 is adjusted to move along the X direction to complete the feeding operation of the armature 7. After the feeding is completed, the guide plate 34 rotates 45° clockwise around the Z axis, so that the guide plate 34 is tilted and attached to the press plate 33, and the armature 7 is allowed to slide to the inclined surface of the cushion block 344 and fit with the inclined portion of the press plate 33, and the slide 31 slides along the Y direction to the press station; Furthermore, the feeding rail 4 makes the electromagnetic element at the corresponding position drive the paddle 43 to expand 0° to 60° around the axis according to the position of the armature 7, and the paddle 43 expands to push the contact piece 8 transported on the feeding rail 4 into the alignment groove 42; This embodiment also includes a relay armature automatic press-fitting method, comprising the following steps: Replace the corresponding pad 344 according to the specifications of the armature 7, and adjust the position of the pad 344 in the guide groove 341 in the guide plate 34, and vibrate and convey the armature 7 of different specifications to the entrances of the three groups of guide grooves 341 of the guide plate 34 through the vibrating material tray 2; make the guide plate 34 be located in the horizontal part of the pressing plate 33, and feed the material into the three guide grooves 341 of the guide plate 34 according to the specifications of the armature 7, and move the guide plate 34 to the inclined part of the pressing plate 33, so that the armature 7 slides along the guide groove 341 and is limited by the pad 344 in the guide groove 341; corresponding to the position of the armature 7, rotate the paddle 43 by the electromagnetic element, so that the contact piece 8 is guided to the alignment groove 42 by the paddle 43, so that the contact piece 8 can fall into the preset position of the armature 7 on the pad 344 through the alignment groove 42; press the contact piece 8 into the pressing position of the armature 7 by the pressing and telescopic machine 5.

[0030] This solution solves the limitation of the traditional relay production line that multiple devices need to be pressed in sequence by means of three sets of guide grooves 341 operating in parallel and the design of adaptive sliding pads 344, and simultaneously completes the positioning, feeding and pressing operations of three specifications of armatures, thereby reducing equipment costs and processing efficiency. On the basis of the above-mentioned embodiment, the above-mentioned pressing telescopic machine 5, the stopping telescopic machine 24 and the delivery telescopic machine 25 can adopt structures such as air cylinders, oil cylinders, motors with lifting rods, etc., which are not limited in this embodiment.
