Description

Technical Field

[0001] The invention belongs to the technical field of electromagnetic coil assembly equipment, and in particular relates to a coil pin assembly device. Background Art

[0002] like Figure 1 As shown in the figure, the electromagnetic coil usually includes a coil frame a and two coil pins b. In the traditional production of electromagnetic coils, the coil pins b of the special-shaped structure are usually assembled manually to the coil frame a, and then the coils are wound to form the electromagnetic coil. With the improvement of the level of automated production, there are also automated production equipment to realize the assembly process of the coil pins b. Figure 2 As shown, the materials conveyed to the automated production equipment include a coil frame a and two material strips c located on both sides of the coil frame a. The material strip c has been preliminarily cut to form a coil pin b with a special-shaped structure, but some connecting parts are retained for better continuous conveying. To realize that the coil frame a and the two material strips c are finally formed into an assembled coil frame a with two coil pins b, two groups of material strip conveying components, one group of coil frame conveying components, one group of stamping components, and two groups of pin pushing components are required. The stamping components are used to stamp the material strip c to separate the coil pin b from the material strip c. The two groups of material strip conveying components, one group of coil frame conveying components, one group of stamping components, and two groups of pin pushing components have corresponding driving mechanisms respectively, and then cooperate with the control system to control each driving mechanism separately to realize that each action is completed in sequence, and each action must leave a sufficient time interval to ensure that other actions can be completed. Therefore, it is difficult to improve production efficiency, and the number of driving mechanisms is large, and the cost of the equipment is also high. Summary of the invention

[0060] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters.

When the fourth sliding block 260 moves toward the one-way ratchet 220, the push tooth 261 pushes the one-way ratchet 220 to rotate, thereby rotating the two material belt conveying wheels 210. When the fourth sliding block 260 is away from the one-way ratchet 220, the one-way ratchet 220 does not rotate. In this embodiment, the elastic member is a compression spring (not shown in the drawings) arranged between the second one-way push block 280 and the fourth sliding block 260.

An elastic member is provided between the first roller 242 and the fixing frame 240 so that the first roller 242 fits the outer periphery of the gear 230. The first roller 242 forms a stepping limit effect on the gear 230 by cooperating with the tooth grooves between the adjacent convex teeth of the gear 230, thereby forming a stepping limit effect on the material belt conveying wheel 210, that is, the material belt conveying wheel 210 can be stepped and rotated at a preset angle as much as possible, so that the material belt c is stepped and conveyed at a preset conveying interval. In this embodiment, the elastic member that acts on the first roller 242 is specifically configured as a compression spring (not shown in the drawings) provided between the first roller 242 and the fixing frame 240.

When the rotary wheel stop driving mechanism 640 is in motion, the pushing tooth 261 of the second one-way push block 280 moves away from the one-way ratchet 220. When the fourth sliding block 260 moves toward the one-way ratchet 220, the pushing tooth 261 cannot normally push the one-way ratchet 220 to rotate. In this embodiment, the rotary wheel stop driving mechanism 640 is specifically a cylinder.

The lower end of the fifth sliding block 552 is fixedly connected to the stamping assembly 300 to realize the reciprocating stamping operation of the stamping assembly 300. In this embodiment, the elastic member is a compression spring (not shown in the drawings) arranged between the fifth sliding block 552 and the fifth guide rail 551.

[0080] like Fig.13As shown, the stamping assembly 300 includes an upper die assembly and a lower die assembly.

Under the action of the sixth guide member 562, the third roller 561 fits the outer peripheral surface of the fourth rotating part 524, and an elastic member is provided to form a force for the sixth sliding block 563 to tend to the rotating shaft 520. During the rotation of the rotating shaft 520, the cam acts on the sixth sliding block 563, and cooperates with the force of the elastic member to make the sixth sliding block 563 reciprocate up and down. There is a connecting plate 564, and two groups of transmission pairs are connected to the connecting plate 564. One group of transmission pairs includes a transverse swing arm 565 and a longitudinal swing arm 566.

Specifically, the transverse swing arm 565 is rotatably connected to one end close to each other and is equipped with a fifth roller 569. The elastic member is a tension spring connected to the frame and the transverse swing arm 565 at one end close to each other. When the sixth sliding block 563 moves downward under the action of the cam thrust, it acts on the fifth roller 569 to press it downward, and the transverse swing arm 565 rotates around the hinge shaft 567, driving the longitudinal swing arm 566 to swing the lower end of the longitudinal swing arm 566 outward. When the sixth sliding block 563 loses the thrust of the cam, the tension spring resets and pulls the transverse swing arm 565 to move the sixth sliding block 563 upward, and at the same time, the lower end of the longitudinal swing arm 566 swings inward.
