Description

Technical Field

[0001] The invention relates to the technical field of ignition coil processing, in particular to terminal assembly equipment for processing automobile ignition coils. Background Art

[0002] In the production process of automobile ignition coils, terminal assembly is a key link, and its assembly quality directly affects the performance and reliability of the ignition coil. Traditional terminal assembly methods rely on manual operation and have many problems. On the one hand, it is difficult to accurately control the position and fit of the terminals through manual operation, which can easily cause the terminals to fall or shift during the assembly process, thereby affecting the accuracy and stability of the assembly, reducing product quality, and increasing the defective rate. On the other hand, due to individual differences among operators, the efficiency of manual operation is difficult to guarantee and cannot meet the needs of large-scale production. In addition, long-term manual operation will increase labor intensity and labor costs. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] In view of the shortcomings of the prior art, the present invention provides a terminal assembly device for processing automobile ignition coils. Through the coordinated work of components such as a spinning cylinder, a double-acting cylinder and an exhaust pump, the terminals can be effectively adsorbed, thereby avoiding the problems of falling and shifting that may occur during assembly and ensuring the accuracy and stability of assembly. The adjustment device can adjust the adsorption requirements according to different usage scenarios, and realize state switching through components such as insertion blocks, so as to facilitate the adjustment of the terminal fit. The upper pressure device uses a single-acting cylinder to drive a lifting device to push the ignition coil close to the terminal position and press it together. The double-acting cylinder can assist in adjusting the pressure to make the pressing process more stable and protect the terminal adsorption port. The rotating ring, protrusion and other components of the rotating device cooperate with the clamping block to clamp the ignition coil at three points to ensure the accuracy of its axial position. The limiting device uses a pen-shaped cylinder to limit and clamp the ignition coil, and cooperates with the rotating device to further optimize the positioning effect.

The adsorption device 2 is used to adsorb the terminal to be installed. The spinning cylinder 21 drives the rotating rod 22 to rotate, and the double-acting cylinder 24 drives the piston 25 to move in the metal tube 23. At the same time, the vacuum pump 26 performs vacuum operation through the rubber tube 27 and the fixed tube 281, the connecting tube 283, the fitting tube 284 and other components of the ventilation device 28. The rotating circle 291 and the magnetic block 294 in the adjustment device 29 can be adjusted according to the adsorption requirements of different usage scenarios.

[0035] The outer wall of the support plate 5 is slidably connected to the side wall of the base 1, the output end of the servo motor 6 is rotatably connected to the inner wall of the limit frame 8, the outer wall of the limit frame 8 is slidably connected to the outer wall of the transmission belt 7, the outer wall of the spinning cylinder 21 and the outer wall of the air pump 26 are fixedly connected to the outer wall of the base 1, the side wall inside the metal tube 23 is slidably connected to the outer wall of the piston 25, the inner wall of the metal tube 23 is fixedly connected to the outer wall of the rubber tube 27, the spinning cylinder 21 drives the rotating rod 22 to rotate at a right angle, thereby controlling the position of the metal tube 23, when the rotating metal tube 23 rotates ninety degrees to reach above the transmission belt 7, the hydraulic cylinder at this time 4 is started, driving the support plate 5 to lift upward, so that the terminal is close to the position of the adsorption device 2. At this time, the vacuum pump 26 of the adsorption device 2 is started. Due to the connection of the rubber tube 27, the internal pipeline of the ventilation device 28 is ventilated, so that the adsorption terminal is attached to the bottom end of the fitting tube 284. At the same time, during use, the adjustment device 29 can be used to make the fitting of the terminal and the fitting tube 284 more stable, and the fitting degree is adjusted without manual direct contact with the terminal. The insertion block 210 is moved, so that the insertion block 210 drives the magnetic block 294 to move through the plug hole 295, wherein the two ends of the magnetic block 294 are The side of the metal tube 23 has strong magnetism and can be fixed to the side wall of the opening of the metal tube 23, so that the magnetic block 294 can be stably fixed at both ends of the opening of the metal tube 23. Due to the movement of the magnetic block 294, the rotating circle 291 drives the limiting ring 292 to rotate, thereby moving the blocking block 293, wherein the blocking block 293 is used to block the position of the vent hole 285. The characteristic that the magnetic block 294 can be fixed at both ends makes the adjustment device 29 have two states, namely, blocking the vent hole 285 and blocking the vent hole 285. When the ventilation device 28 and the adjustment device 29 need to work together, When the terminal is fitted stably, first set the blocking block 293 to block the position of the vent hole 285. At this time, start the double-acting cylinder 24, which drives the piston 25 to rise. As the piston 25 rises, the space in the closed structure formed by the blocking block 293 and the ventilation device 28 increases, thereby reducing the pressure. At this time, move the metal tube 23 to the top of the terminal and start the vacuum pump 26. The air flow in the rubber tube 27 is continuously extracted through the hole in the middle of the fitting tube 284, the connecting tube 283 and the fixed tube 281 fixed by the fixing block 282, thereby forming air pressure, thereby adsorbing the terminal.

At this time, the double-acting cylinder 24 is started again, so that the piston 25 is started and pushed downward. Since the terminals are tightly fitted before and a closed space is formed inside the metal tube 23 again, pushing the piston 25 at this time will increase the pressure in the closed space. The internal air seeks pressure balance, thereby pushing and pressing the fitted terminals onto the ignition coil. Cooperating with the pushing action of the single-acting cylinder 31, the pressing process is more stable.

[0037] Third embodiment: Please refer to Figure 1-9 The present invention provides a technical solution: the upper pressing device 3 includes a single-acting cylinder 31, the output end of the single-acting cylinder 31 is fixedly connected to a lifting device 32, the side wall of the lifting device 32 is fixedly connected to a fixed shell 33, the outer wall of the fixed shell 33 is fixedly connected to a limiting device 37, the outer wall of the lifting device 32 is rotatably connected to a rotating device 34, the inner wall of the bottom of the lifting device 32 is fixedly connected to a damping rod 35, and the outer sleeve of the damping rod 35 is provided with a reset spring 36.

The rotating ring 341, protrusion 342 and other components of the rotating device 34 can be rotated according to the clamping needs. The rotating ring 341 and the connecting ring 343 can move stably on the slide rail 322 through the slider 344. At this time, the rotating rotating ring 341 will drive the protrusion 342 to move, and then the protrusion 342 will push the clamping block 323 to move. Since the clamping block 323 is limited by the limit block 324, the telescopic rod 325 and the tension spring 326, the clamping block 323 can be stably withdrawn. The arrangement of the three groups of clamping blocks 323 and their accessories allows the ignition coil to be clamped at three points, thereby ensuring stable clamping and determining that the ignition coil is located at the axial center position.

[0044] When in use, the base 1 serves as the foundation of the entire device, providing a stable support for each component. The adsorption device 2 is used to adsorb the terminal to be installed. The spinning cylinder 21 drives the rotating rod 22 to rotate, and the double-acting cylinder 24 drives the piston 25 to move in the metal tube 23. At the same time, the air pump 26 performs an air extraction operation through the rubber tube 27 and the fixed tube 281, the connecting tube 283, the fitting tube 284 and other components of the ventilation device 28. The rotating circle 291 and the magnetic block 294 in the adjustment device 29 can be adjusted according to the adsorption requirements of different usage scenarios.

[0045] In actual operation, the terminals are arranged on the transmission belt 7 in sequence, and the movement of the terminals is controlled by the limiting effect of the limiting frame 8 and the driving effect of the servo motor 6. The ignition coil is inserted into the bottom end of the single-acting cylinder 31, and when it is completely placed in the lifting device 32, the ignition coil is clamped and positioned by the rotating device 34, and the spinning cylinder 21 drives the rotating rod 22 to rotate at a right angle, thereby controlling the position of the metal tube 23. When the rotating metal tube 23 rotates ninety degrees to reach above the transmission belt 7, the oil hydraulic cylinder 4 is started at this time, driving the support plate 5 to lift upward, thereby making the terminal close to the position of the adsorption device 2. At this time, the vacuum pump 26 of the adsorption device 2 is started. Due to the connection of the rubber tube 27, the internal pipeline of the ventilation device 28 is ventilated at this time, and then the adsorption terminal is attached to the bottom end of the fitting tube 284. At the same time, during use, the adjustment device 29 can be used to make the fitting of the terminal and the fitting tube 284 more stable, and the fitting degree can be adjusted without manual direct contact with the terminal.

[0046] By moving the insertion block 210, the insertion block 210 can drive the magnetic block 294 to move through the plug hole 295, wherein the two sides of the magnetic block 294 have strong magnetism and can be fitted and fixed with the side walls of the opening of the metal tube 23, so that the magnetic block 294 can be stably fixed at both ends of the opening of the metal tube 23. Due to the movement of the magnetic block 294, the rotating circle 291 drives the limiting ring 292 to rotate, thereby moving the blocking block 293, wherein the blocking block 293 is used to block the position of the vent hole 285. The characteristic that the magnetic block 294 can be fixed at both ends makes the adjustment device 29 have two states, namely, blocking the vent hole 285 and blocking the vent hole 285. When the joint action of the ventilation device 28 and the adjustment device 29 is required to make the terminal fit stably, the blocking block 293 is first set to block the position of the vent hole 285, and then the double-acting cylinder 24 is started. , and then drive the piston 25 to rise. As the piston 25 rises, the space in the closed structure formed by the blocking block 293 and the venting device 28 increases, thereby reducing the pressure. At this time, the metal tube 23 is moved to the top of the terminal, and the vacuum pump 26 is started. The air flow in the rubber tube 27 is continuously extracted through the middle hole of the fitting tube 284, the connecting tube 283 and the fixed tube 281 fixed by the fixing block 282, thereby forming air pressure, thereby adsorbing the terminal. At this time, the terminal is prone to tilt due to the impact due to the instantaneous adsorption force. At this time, the insertion block 210 is moved again, so that the blocking block 293 withdraws from the blocking of the vent 285. At this time, due to the reduction of pressure in the closed space, air will be sucked from the vent 285 in order to balance the air pressure. At this time, the vent 285 generates adsorption force, thereby adsorbing the terminal on the adsorption device 2, thereby adjusting the fitting state of the terminal;

[0047] When the spinning cylinder 21 is started again, the metal tube 23 on the rotating rod 22 reaches the upper part of the pressing device 3, and the pressing device 3 is started to push the ignition coil close to the terminal position and press it. At this time, the double-acting cylinder 24 is started again, so that the piston 25 is started and pushed downward. Since the terminals are tightly fitted before and a closed space is formed inside the metal tube 23 again, pushing the piston 25 at this time will increase the pressure in the closed space. The internal air seeks pressure balance, and then the fitted terminals are pushed and pressed on the ignition coil. With the pushing effect of the single-acting cylinder 31, the pressing process is more stable and the terminal adsorption port is protected.

[0048] The single-acting cylinder 31 of the upper pressure device 3 drives the lifting device 32 to move. The lifting shell 321 and the slide rail 322, the limit block 324, the clamping block 323 and other structures thereon can lift and position the ignition coil components. The rotating ring 341, the protrusion 342 and other components of the rotating device 34 can be rotated according to the clamping needs. The rotating ring 341 and the connecting ring 343 are stably moved on the slide rail 322 through the slider 344. At this time, the rotating rotating ring 341 will drive the protrusion 342 to move, and then the protrusion 342 will push the clamping block 323 to move. Since the clamping block 323 is limited by the limit block 324, the telescopic rod 325 and the tension spring 326, the clamping block 323 can be stably withdrawn. The three groups of clamping blocks The arrangement of 323 and its accessories enables the ignition coil to be clamped at three points, thereby ensuring stable clamping and determining that the ignition coil is located at the axial center position. At the same time, a limiting device 37 is arranged to fix the clamping block 323. The pen-shaped cylinder 372 on the fixing bar 371 pushes the positioning shaft 373. Through the cooperation of the limiting tube 374 and the pressure relief groove 375, the positioning shaft 373 is stably pushed out through the fixing shell 33 and enters the positioning hole 345 of the slider 344, thereby fixing the clamping position of the ignition coil. At this time, the single-acting cylinder 31 lifts the ignition coil upward, and the damping rod 35 and the reset spring 36 provide buffering and reset functions, ensuring stability during operation, and accurately limiting and positioning the ignition coil components.

[0049] The servo motor 6 drives the limit frame 8 to rotate through the transmission belt 7, and transfers the component carrying the ignition coil component to the appropriate position. The hydraulic cylinder 4 pushes the support plate 5 to move up and down, so that the adsorption device 2 and the upper pressure device 3 move relative to each other, and the adsorbed terminal is accurately assembled on the ignition coil component;

[0050] Through the adsorption function of the adsorption device 2 and the adjustment function of the adjustment device 29, the tilted state of the terminal can be handled; the upper pressing device 3 can position and limit the ignition coil components; the risk of human operating errors is reduced, automated terminal assembly is realized, and production costs and labor intensity are reduced.
