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, the electromagnetic coil usually includes a coil frame a and two coil pins b. In traditional production of electromagnetic coils, the coil pins b with special shapes 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 now automated production equipment to realize the assembly process of the coil pins b. Figure 2 As shown, the materials fed to the automated production equipment include a coil bobbin a and two strips c, one on each side of the coil bobbin a. Strips c have been preliminarily cut to form the shaped coil pins b, but some connections remain to facilitate continuous conveying. To achieve the final formation of the coil bobbin a and the two strips c into the assembled coil bobbin a with two coil pins b, two sets of strip conveying assemblies, one set of coil bobbin conveying assemblies, one set of stamping assemblies, and two sets of pin pushing assemblies are required. The stamping assemblies are used to stamp the strips c to separate the coil pins b from the strips c. Each of the two strip conveying assemblies, one set of coil bobbin conveying assemblies, one set of stamping assemblies, and two sets of pin pushing assemblies has a corresponding drive mechanism. A control system independently controls each drive mechanism to achieve sequential completion of each action. Each action must be separated by sufficient time intervals to ensure that the others can complete. Consequently, production efficiency is difficult to improve. Furthermore, the large number of drive mechanisms increases the cost of the equipment. Summary of the Invention

[0059] In order to make the objects, technical solutions and advantages of the present application clearer, the following further describes the present application with reference to the accompanying drawings.

[0060] It should be noted that all the expressions of "first" and "second" in the embodiments of the present application are used to distinguish two same-named different entities or different parameters. It can be seen that "first" and "second" are only used for the convenience of description and should not be understood as a limitation on the embodiments of the present application. The subsequent embodiments will not be described one by one.

[0061] The direction and position terms mentioned in the present application, such as up, down, front, back, left, right, inner, outer, top, bottom, side, etc., are only the directions or positions of the drawings. Therefore, the direction and position terms used are used to illustrate and understand the present application, and are not a limitation on the scope of protection of the present application.

[0062] A coil pin assembly device, as shown in Figure 3 , comprises a rack, a coil skeleton conveying assembly 100, a material belt conveying assembly 200, a stamping assembly 300 and a pin pushing assembly 400. The coil skeleton conveying assembly 100 is used to convey a coil skeleton a. The material belt conveying assembly 200 is used to convey two material belts c located on both sides of the conveyed coil skeleton a. The stamping assembly 300 is used to stamp the two material belts c to obtain two coil pins b. The pin pushing assembly 400 is used to push the two coil pins b from the left and right sides of the coil skeleton a into the coil skeleton a, thereby completing the coil pin assembly device.

[0063] Further comprising a driving assembly 500, as shown in Figure 4 , the driving assembly 500 comprises a driving mechanism 510 and a transmission assembly. The transmission assembly comprises an input part 501 connected with the output shaft of the driving mechanism 510, a first output part connected with the coil skeleton conveying assembly 100 in transmission cooperation, a second output part connected with the material belt conveying assembly 200 in transmission cooperation, a third output part connected with the stamping assembly 300 in transmission cooperation, and a fourth output part connected with the pin pushing assembly 400. That is, when the driving mechanism 510 drives the input part 501, the first output part, the second output part, the third output part and the fourth output part synchronously output driving force, thereby driving the coil skeleton conveying assembly 100, the material belt conveying assembly 200, the stamping assembly 300 and the pin pushing assembly 400 to synchronously act, realizing that one driving mechanism 510 outputs driving force to synchronously drive the coil skeleton conveying assembly 100, the material belt conveying assembly 200, the stamping assembly 300 and the pin pushing assembly 400 to act at the same time. In this way, the cost is saved, and at the same time, it is not necessary to consider whether the time interval of each action is sufficient to meet the reaction time of other actions, thereby greatly improving the production efficiency.

[0064] Specifically, the driving mechanism 510 is a rotary driving mechanism, which can be a motor, a hydraulic cylinder, etc. In this embodiment, a rotary motor is specifically used. Figure 4 As shown, the transmission assembly includes a rotating shaft 520, on which a first rotating part 521, a second rotating part 522, a third rotating part 523, and a fourth rotating part 524 that rotate synchronously are provided. The first rotating part 521, the second rotating part 522, the third rotating part 523, and the fourth rotating part 524 are respectively matched with the first output part, the second output part, the third output part, and the fourth output part for transmission.

[0065] The first rotating part 521 is a guide groove opened on the rotating shaft 520, and the first output part is a first sliding block 532 equipped with a first guide rail member 531. The first guide rail member 531 is fixed on the frame. Under the action of the first guide rail member 531, the first sliding block 532 only moves along the axial direction of the rotating shaft 520. The first sliding block 532 is plugged into the guide groove. During the rotation of the rotating shaft 520, the first sliding block 532 moves back and forth along the axial direction of the rotating shaft 520 under the guidance of the guide groove.

[0066] The coil frame conveying assembly 100 includes a coil positioning fixture 110, a fixture passage 120, a fixture push rod 130, a fixture guide rail 140, and a fixture stepping push assembly 150. The coil positioning fixture 110 is used to fix a plurality of coil frames a arranged in sequence along the conveying direction. Its structure is as follows: Figure 5 As shown, it includes a clamp base body 111, the upper end of the clamp base body 111 is provided with a plurality of coil fixing positions 112 and the lower end is provided with a push groove 113 corresponding to the number and position of the coil fixing positions 112.

The fixture aisle 120 is arranged at the front end of the conveying track 141 formed by the fixture guide rail part 140. The fixture push rod 130 is used to push the coil positioning fixture 110 in the fixture aisle 120 onto the conveying track 141 formed by the fixture guide rail part 140. The fixture stepping pushing assembly 150 is arranged at the lower end of the conveying track formed by the fixture guide rail part 140, and cooperates with the pushing groove 113 at the lower end of the coil positioning fixture 110 to realize the stepping movement of the coil positioning fixture 110 along the conveying track.

[0067] The corresponding rotating shaft 520 is provided with a rotation detection sensor 570 for detecting its rotation, specifically a proximity sensor provided corresponding to the first rotating part 521. Since the first rotating part 521 is a guide groove, the rotation detection sensor 570 corresponds to the first rotating part 521 for detection in the area where the radial position changes. After the rotating shaft 520 rotates one circle, the rotation detection sensor 570 can accurately identify and count. When the number of rotations of the rotating shaft 520 is the same as the fixed number of coil skeletons a installed by the coil positioning fixture 110, all coil skeletons a on a coil positioning fixture 110 are assembled, and the next coil positioning fixture 110 needs to be transported, that is, the coil positioning fixture 110 is loaded into the fixture aisle 120, and then pushed to the conveying track 141 formed by the fixture guide rail 140 through the fixture push rod 130.

When the first sliding block 532 moves back and forth along the axial direction of the rotating shaft 520, the compression spring acts to make the second sliding block 152 slide back and forth along the conveying direction. The first one-way push block 154 is hingedly connected to the second sliding block 152 and its upper end protrudes relative to the upper end of the second sliding block 152 so that it is inserted into the pushing groove 113. The two sides of the upper end of the first one-way push block 154 are respectively a vertical surface 1541 and an action inclined surface 1542. The second sliding block 152 is provided with a limit pin 1522 located on one side of the vertical surface 1541 to form a limit on the vertical surface 1541. The first one-way push block 154 can rotate to a first position with the vertical surface 1541 abutting the limit pin 1522 and a second position with the vertical surface 1541 leaving the limit pin 1522. When the second sliding block 152 slides back and forth along the conveying direction, the vertical surface 1541 and the action inclined surface 1542 interact alternately with the clamp base body 111. When the vertical surface 1541 acts When the clamp base body 111 is in the state of rotation, the torsion spring 155 acts on the first one-way push block 154 to keep the first one-way push block 154 in the first position. The vertical surface 1541 pushes the coil positioning clamp 110 to step one position along the conveying track. When the action inclined surface 1542 acts on the clamp base body 111, the clamp base body 111 pushes the first one-way push block 154 to turn to the second position and leave one push groove 113. Under the action of the torsion spring 155, it returns to the next push groove 113, so that the rotating shaft 520 rotates one circle, the first pull wire 153 is pulled and reset, the second sliding block 152 completes a reciprocating slide, and the first one-way push block 154 pushes the coil positioning clamp 110 to step one position along the conveying track and reset into the next push groove 113.

In this embodiment, a compression spring (not shown in the accompanying drawings) is specifically used between the frame and the fourth sliding block 260; a second wire pull fixing plate 290 is hinged on the fixed frame 240, one end of the second wire pull fixing plate 290 is hingedly connected to the fourth sliding block 260 and the other end is fixedly connected to one end of the second wire pull 270, the second wire pull 270 passes through the second wire pull limit plate 241 and the other end is fixedly connected to the third sliding block 542, when the third sliding block 542 moves back and forth along the axial direction of the rotating shaft 520, the compression spring acts to make the fourth sliding block 260 slide back and forth along the conveying direction.

[0075] like Figure 10 As shown, the second one-way push block 280 is hingedly connected to the fourth sliding block 260 and is provided with a pushing tooth 261. An elastic member acts on the second one-way push block 280 to cause the pushing tooth 261 to engage with the outer periphery of the one-way ratchet 220. When the fourth sliding block 260 moves toward the one-way ratchet 220, the pushing tooth 261 pushes the one-way ratchet 220 to rotate, thereby rotating the two material conveying wheels 210. When the fourth sliding block 260 moves 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) disposed between the second one-way push block 280 and the fourth sliding block 260.

[0076] like Figure 11 As shown, the fixed frame 240 is further provided with a first roller 242 that can move up and down relative to the fixed frame 240. An elastic member is provided between the first roller 242 and the fixed frame 240, allowing the first roller 242 to fit the outer circumference of the gear 230. The first roller 242 cooperates with the tooth grooves between adjacent protruding teeth of the gear 230 to form a step-by-step limit for the gear 230, thereby forming a step-by-step limit for the material conveying wheel 210. This allows the material conveying wheel 210 to rotate stepwise according to a preset angle, thereby achieving step-by-step conveyance of the material c according to 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) disposed between the first roller 242 and the fixed frame 240.

Figure 10 As shown, the wheel stop drive mechanism 640 is disposed on the fourth sliding block 260 and cooperates with the second one-way push block 280. When the wheel stop drive mechanism 640 is actuated, the push teeth 261 of the second one-way push block 280 move away from the one-way ratchet 220. When the fourth sliding block 260 moves toward the one-way ratchet 220, the push teeth 261 are unable to properly rotate the one-way ratchet 220. In this embodiment, the wheel stop drive mechanism 640 is specifically implemented as a pneumatic cylinder.

[0079] The third rotating portion 523 is a cam that rotates synchronously on the rotating shaft 520. The third output portion is a fifth sliding block 552 that is coupled with a fifth guide member 551. The fifth guide member 551 is fixed to the frame. Under the action of the fifth guide member 551, the fifth sliding block 552 only slides upward along the rotating shaft 520. The fifth sliding block 552 is rotatably connected to a second roller 553. The second roller 553 is in contact with the outer circumference of the third rotating portion 523. An elastic member is provided to force the fifth sliding block 552 toward the rotating shaft 520. During the rotation of the rotating shaft 520, the cam acts on the fifth sliding block 552, and the force of the elastic member causes the fifth sliding block 552 to slide back and forth up and down. The lower end of the fifth sliding block 552 is fixedly connected to the stamping assembly 300, thereby realizing the reciprocating stamping operation of the stamping assembly 300. In this embodiment, the elastic member is a compression spring (not shown in the drawings) disposed between the fifth sliding block 552 and the fifth guide member 551.

[0080] like Figure 13As shown, the stamping assembly 300 includes an upper die assembly and a lower die assembly. The specific structure of the upper die assembly and the lower die assembly is the structure of the existing conventional blanking device and will not be elaborated here. The upper die assembly cooperates with the fifth sliding block 552. The upper die assembly includes a pin punch 310, a strip punch 320, and a strip positioning needle 330. The strip positioning needle 330 is used to cooperate with the positioning hole c1 of the strip c to prevent the strip c from moving. The lower die assembly is fixed on the frame and includes a blade plate 350 fixed above the fixture guide rail 140 and a blade pressure plate 340 fixed above the blade plate 350.

The fourth rotating part 524 is matched with a sixth sliding block 563 that is rotatably connected to the third roller 561 and is matched with a sixth guide member 562. Under the action of the sixth guide member 562, the third roller 561 is attached to 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 with the force of the elastic member, the sixth sliding block 563 slides back and forth 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. The two transverse swing arms 565 are located in the same horizontal direction and one end is close to each other and located below the sixth sliding block 563. The other end of the transverse swing arm 565 is connected to a hinge shaft 567 that forms a circumferential linkage. The hinge shaft 567 can be rotated through the connecting plate 564 to connect to the longitudinal swing arm 566, and the hinge shaft 567 and the longitudinal swing arm 566 form a circumferential linkage. The longitudinal swing arm 566 is set close to the longitudinal direction, and its lower end constitutes the fourth output part. Specifically, the transverse swing arm 565 is connected to the fifth roller 569 by rotating at one end close to each other. 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, causing the sixth sliding block 563 to move upward, and at the same time the lower end of the longitudinal swing arm 566 swings inward.

[0082] The pin pushing assembly 400 includes a seventh guide rail 410, a seventh sliding block 420, a push rod 430, and a push block 440.
