[0042] The implementation of the present application will be described in detail below in conjunction with specific embodiments.

[0043] The present scheme aims to solve the problem that the traditional relay generally has three groups of armatures, each group of armatures has different functions, different shapes, and different contact pressing positions, so in the production process, different shape armatures of different specifications of relays often need to be configured with multiple pressing equipment respectively, which is high in cost; and if pressing is performed by a single machine, repeated positioning needs to be performed according to the shape of the armature, which affects the production efficiency.

[0044] In the present embodiment:

[0045] Referring to Figure 1-Figure 3 and Figure 6 , a preferred embodiment of the present application is provided.

[0046] The relay armature automatic pressing equipment of the present embodiment comprises:

[0047] A pressing platform 1 is provided with a positioning member 3, the positioning member 3 comprises a pressing plate 33, one end of which is a horizontal part and the other end is an inclined part, and the included angle between the inclined part and the horizontal part is 45°;

[0048] The guide plate 34 can slide in the X and Y directions and can rotate in the Z direction, sliding back and forth on the horizontal portion and the inclined portion of the pressing plate 33;

[0049] Three sets of guide grooves 341 are evenly spaced 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.

[0050] The feed rail 4, whose end extends to above the pad 344 of the inclined portion of the press-fit plate 33, includes: a positioning piece 41 having a positioning groove 42 corresponding to the positioning coordinates of the contact pieces 8 of different specifications to prevent the contact pieces 8 from being offset from the press-fit position of the armature 7; a paddle 43, which is hinged to the side wall of the feed rail 4 away from the positioning groove 42 via a spring shaft and is driven by an electromagnetic element to expand in a fan-shaped manner around the axis by 0°-60°, for guiding the contact pieces 8 to fall into the preset position of the armature 7 on the pad 344;

[0051] The press-fit telescopic machine 5 is obliquely installed at the end of the inclined part of the positioning member 3, and the movement direction of its telescopic part is parallel to the inclined part of the press-fit plate 33. A pressure head is provided at the end of the telescopic part for press-fitting the contact piece 8 onto the armature 7 of the pad 344.

[0052] Among them, the positioning member 3 also includes a slide 31, which is set on the press-fitting platform 1 for sliding along the Y direction, and the guide plate 34 slides on the slide 31 along the X direction. A slide 32 is installed on the slide 31 for sliding along the X-axis direction. The slide 32 is set in a "冂" shape. The guide plate 34 shaft is connected to the ends of the vertical parts on both sides of the slide 32. The guide plate 34 completes the functions of sliding in the Y direction and rotating along the Z direction through the slide 32.

[0053] Furthermore, the device also includes a vibrating material tray 2, which is docked with the entrance of the guide groove 341 when the guide plate 34 is in a horizontal state, and is used to transport the armature 7 into the guide groove 341. The armature 7 slides along the guide groove 341 and is limited by the pad 344. The pressing platform 1 is located between the vibrating material tray 2 and the positioning member 3 and is provided with a guide rail 21 and a loading rail 22 that are staggered and distributed in parallel with each other. A stopping telescopic machine 24 is installed on one side of the end of the guide rail 21. The telescopic part of the stopping telescopic machine 24 is used to stop the armature 7 and transfer it to the loading rail 22, so that the armature 7 can enter the guide groove 341 of the guide plate 34 one by one to avoid mutual interference.

[0054] A delivery telescopic machine 25 is installed above the feeding rail 22 near the guide rail 21. The telescopic part of the delivery 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 consistent with that of the feeding rail 22. The push rod 26 can push the armature 7 transferred to the feeding rail 22 into the guide groove 341 of the guide plate 34.

[0055] It is worth noting that an identification sensor 23 is also installed below the feeding rail 22 near the guide rail 21. The identification sensor 23 is one or more visual sensors or photoelectric sensors, which are used to identify the edge projection of the armature 7 (based on contour matching or size measurement mapping of the matching database), and cooperate with external PLC programming to realize the identification of the armature 7, so as to judge the specifications of the armature 7, and introduce it into the corresponding guide groove 341 according to the specifications of the armature 7, and drive one group of paddles 43 to guide the position of the contact piece 8 according to the specifications of the armature 7.

[0056] In the attached Figure 4 and attached Figure 5 The end bearing of the guide plate 34 is connected to a rotating rod 342, and the pad 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 that meshes with the driving gear 343. When the guide plate 34 is tilted and slides 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 with its external threaded connection to slide in the guide plate 34, so as to adjust the relative position of the press-fitting part of the armature 7 and the positioning piece 41 according to different specifications of the armature 7, so that the contact piece 8 can correspond to the press-fitting position of the armature 7. When the armature 7 is press-fitted, the adjusting motor 35 drives the pad 344 to slide out of the guide plate 34, so that the armature 7 press-fitted on the pad 344 falls off and is collected, so that the press-fitting operation of the next armature 7 can continue.

[0057] Among them, the side surface of the pad 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 pad 344, completing the limit and realizing automatic physical positioning.

[0058] Further, see the attached Figure 6 As shown, a collecting belt 61 is provided on the end surface of the inclined portion of the pressing plate 33, and a collecting tray 6 is provided at the end of the pressing platform 1 located at the collecting belt 61. When the armature 7 pressed on the pad 344 falls off, it will be directly received by the collecting belt 61 and then pushed into the collecting tray 6 for collection;

[0059] Finally, the telescopic portion of the press-fitting telescopic machine 5 moves vertically along the inclined portion 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, eliminating the stress concentration caused by the angle deviation, and pressing the contact piece 8 into the press-fitting position of the armature 7;

[0060] Among them, the pressing head is equipped with a pressure sensor for pressure signal collection and feedback to improve the pressing effect.

[0061] In this 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, and the slide 31 moves along the Y direction to the horizontal end of the guide plate 34 to receive the material, and adjusts the guide plate 34 to move along the X direction to complete the loading operation of the armature 7. After the loading 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, allowing the armature 7 to slide onto the inclined surface of the pad 344 and fit into the inclined portion of the press plate 33. The slide 31 slides along the Y direction to the press station;

[0062] Furthermore, the feed rail 4 causes the electromagnetic element at the corresponding position to drive the paddle 43 to expand 0° to 60° around the axis according to the position of the armature 7. The paddle 43 expands to push the contact piece 8 transported on the feed rail 4 into the alignment slot 42.

[0063] This embodiment also includes a method for automatically pressing a relay armature, comprising the following steps:

[0064] 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 armatures 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, the electromagnetic element rotates the paddle 43, so that the contact piece 8 is guided by the paddle 43 to the alignment groove 42, 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; and the contact piece 8 is pressed into the pressing position of the armature 7 by the pressing and retracting machine 5.

[0065] This solution overcomes the limitation of traditional relay production lines requiring multiple devices to press-fit in sequence by using three sets of guide grooves 341 operating in parallel and the design of adaptive sliding pads 344. It simultaneously completes the positioning, feeding and press-fitting operations of three sizes of armatures, reducing equipment costs and processing efficiency.

[0066] On the basis of the above embodiment, the above-mentioned pressing telescopic machine 5, the stopping telescopic machine 24 and the delivery telescopic machine 25 can be made of structures such as air cylinders, oil cylinders, and motors with lifting rods, which are not limited in this embodiment.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
