Description

Technical Field

[0001] The invention relates to the technical field of processing equipment, and in particular to a built-in coil material taking, soldering and detection equipment for an ignition coil. Background Art

[0002] As automobile gasoline engines develop towards high speed, high compression ratio, high power, low fuel consumption and low emissions, traditional ignition devices are no longer suitable for use. The core components of the ignition device are the ignition coil and the switch device. By increasing the energy of the ignition coil, the spark plug can generate sparks with sufficient energy, which is the basic condition for the ignition device to adapt to the operation of modern engines.

[0003] The ignition coil needs to go through multiple steps during the processing: dust removal, soldering, assembly, conduction test and high and low voltage test. Dust removal is to remove dust on the winding to prevent breakdown. Rosin is needed to assist soldering, and then tin is dipped for soldering. During the assembly process, the high-voltage nozzle needs to be installed at the front end of the built-in coil, which is also called a high-voltage wire package. The built-in coil is then assembled in the outer shell to form an ignition coil. After the above assembly process is completed manually, the ignition coil is tested for conduction and high and low voltage. During the processing, workers need to have rich experience, otherwise the consistency between different ignition coils is low, the quality is poor, and higher labor costs are required. In addition, long-term manual processing is prone to fatigue, and false detection and missed detection are prone to occur during the detection process. Summary of the invention

[0004] The object of the present invention is to provide a built-in coil material taking, soldering and testing equipment for an ignition coil, which has the effects of high automation, low labor cost, and good quality and consistency.

[0008] The assembly detection device includes a chain assembly, an assembly mechanism and a high and low voltage detection mechanism. A plurality of bases are arranged on the chain assembly, and the bases are driven to move when the chain assembly is driven.

[0009] By adopting the above technical scheme, during the processing of the ignition coil, the manipulator grabs the built-in coil that has been wound from the unwinding rack, and then extends it into the sleeve to remove dust through a suction pump; the manipulator solders the built-in coil after dust removal on the soldering device, first dips rosin in the rosin adding mechanism, and then solders the two ends of the coil through the tinning mechanism, and then cools and irons the two ends of the coil on the cooling column respectively; when the high-voltage nozzle is installed at the front end of the built-in coil, the feeding mechanism sends out the high-voltage nozzle for installation in turn, and the manipulator cooperates with the installation structure to install the high-voltage nozzle at the front end of the built-in coil. During the installation, the conduction detection module can be used to detect whether the built-in coil and the high-voltage nozzle are conductive; finally, the built-in coil is assembled on the shell, the shell is placed on the base, the chain assembly conveys the base to the assembly mechanism, and the manipulator cooperates with the assembly mechanism to assemble it into an ignition coil, and then the chain assembly moves the base with the ignition coil to the high and low voltage detection mechanism for high and low voltage detection, so that the processing process has a high degree of automation, good quality and consistency, and low labor cost.

When the pushing cylinder pushes the lifting frame to rise, the feeding barrel is filled with rosin and the rosin is sent out of the rosin storage box for dipping.

[0013] By adopting the above technical solution, the tin coil is placed on the tin coil placement rack, and the driving cylinder drives the sliding platform to move towards or away from the high-temperature tin coating table. When the driving cylinder makes the sliding platform close to the high-temperature tin coating table, the front end of the tin bar is transmitted to the high-temperature tin coating table through the tin coil transmission structure, and the tin bar is melted on the high-temperature tin coating table. The driving cylinder drives the sliding platform away from the high-temperature tin coating table and drives the push-flattening block to move at the same time, so that the push-flattening block spreads the molten liquid tin through the inclined surface during the movement, which can avoid a large amount of liquid tin from being dipped on the coil at both ends when dipping tin to a certain extent, thereby improving the quality of solder.

When the driving shaft rotates driven by the output shaft of the driving motor, the driving wheel is driven to rotate. The rotation of the driving wheel can drive the first guide wheel and the second guide wheel to rotate synchronously, thereby transferring the tin bar to the high-temperature tin coating table for melting.

At the same time, conduction is achieved between the first electrode 324 and the second electrode 325, and the conduction detection module 33 can detect the conduction between the high-voltage nozzle and the coil.

[0054] like Figure 1 and Figure 8 As shown, the assembly detection device 4 includes a chain assembly 41, an assembly mechanism 42 and a high and low voltage detection mechanism 43. The chain assembly 41 is provided with a plurality of bases 411, and the bases 411 are driven to move when the chain of the chain assembly 41 is driven. The assembly mechanism 42 includes a first support 421, a cylinder assembly and a blanking block 423. The first support 421 is fixedly arranged on the workbench 1. The cylinder assembly includes a connecting block 424, a horizontal thrust cylinder 422 and a first downward pressure cylinder 425. The horizontal thrust cylinder 422 drives the connecting block 424 to move. The first downward pressure cylinder 425 is fixedly installed on the upper end of the connecting block 424. The blanking block 423 is fixedly connected to the piston rod of the first downward pressure cylinder 425. A limiting portion 4231 is provided on the blanking block 423. The limiting portion 4231 is provided with a vertical U-shaped groove 4232. The U-shaped groove 4232 is adapted to the built-in coil.

[0055] During the assembly process, the shell is manually placed on each base 411 so that the opening of the shell faces upward, and the manipulator 11 places the built-in coil processed in the previous step above the shell opening. The horizontal thrust cylinder 422 pushes the connecting block 424 to move closer to the base 411, and then the first downward pressure cylinder 425 drives the material block 423 to move downward, so that the built-in coil can be pushed away from the manipulator 11 and pressed into the shell to assemble into an ignition coil. In this way, the pressure during press-fitting is more uniform, and the different ignition coils after assembly have higher consistency.

[0056] like Figure 8 and Fig. 9As shown, the high and low voltage detection mechanism 43 includes a second support 431, a third electrode 432, a fourth electrode 433 and a high and low voltage detection module (not shown in the figure), and the high and low voltage detection module is electrically connected to the third electrode 432 and the fourth electrode 433; a second downward pressing cylinder 434 is arranged vertically downward on the second support 431, and a pressing block 435 is arranged on the piston rod of the second downward pressing cylinder 434, the third electrode 432 is fixedly connected to the pressing block 435, and the second downward pressing cylinder 434 drives the pressing block 435 to move toward the base 411; a vertical downward lifting cylinder 436 is also arranged on the second support 431, and a moving block 437 is arranged on the piston rod of the lifting cylinder 436, and a pushing cylinder 438 is fixedly connected to the moving block 437, and the pushing cylinder 438 is arranged horizontally, and a second mounting sleeve 439 is arranged on the piston rod of the pushing cylinder 438, and the fourth electrode 433 is arranged on the second mounting sleeve 439.

[0057] During high and low voltage detection, the second downward pressure cylinder 434 drives the downward pressure block 435 to press down, so that the third electrode 432 presses against the low-pressure end of the upper end of the ignition coil, and the pushing cylinder 438 drives the fourth electrode 433 on the mounting sleeve to move to the bottom of the ignition coil, and then the lifting cylinder 436 drives the moving block 437 to move upward, so that the fourth electrode 433 presses against the high-pressure end of the lower end of the ignition coil, so that conduction can be achieved.

[0058] like Figure 8 and Fig.10 As shown, the assembly detection device 4 also includes a positioning structure 8, which includes a lifting cylinder 81 and a clamping cylinder 82. A base plate 412 is provided at the bottom of the chain assembly 41. The lifting cylinder 81 is fixedly connected to the base plate 412. A lifting block 83 is fixedly connected to the piston rod of the lifting cylinder 81. A stopper 84 and a mounting block 85 are provided on the lifting block 83. The clamping cylinder 82 is fixedly connected to the mounting block 85. A clamping block 86 is fixedly connected to the piston rod of the clamping cylinder 82. A hook 861 is provided on the upper end of the clamping block 86. The clamping cylinder 82 drives the clamping block 86 to move toward the stopper 84, so that the clamping block 86 and the stopper 84 clamp and fix the base 411. When assembling or testing, the base 411 can be positioned by the positioning structure 8, and the lifting cylinder 81 pushes the lifting block 83 to rise, so that the stop block 84 and the clamping block 86 extend into the track of the chain assembly 41, and one side of the base 411 abuts against the stop block 84, and the clamping cylinder 82 pushes the clamping block 86 to move horizontally toward the stop block 84 until the clamping block 86 abuts against the other side of the base 411. In this way, the base 411 can be positioned by the clamping block 86 and the stop block 84.

[0059] The basic working principle of the present invention is as follows: the manipulator 11 solders the dust-removed built-in coil on the soldering device 2, firstly dips rosin in the rosin adding mechanism 21, then solders the two ends of the coil through the tinning mechanism 22, and then cools and irons the two ends of the coil on the cooling column 23 respectively; when the built-in coil is installed with a high-voltage nozzle, firstly bend the two ends of the winding on the bending wheel 73, the feeding mechanism 31 sequentially feeds out the high-voltage nozzle for installation, and pre-installs the high-voltage nozzle, the manipulator 11 cooperates with the installation structure 32 to install the high-voltage nozzle at the front end of the built-in coil, and then installs the high-voltage nozzle. During the assembly, the conduction detection module 33 can be used to detect whether the built-in coil and the high-voltage nozzle are conductive; finally, the built-in coil is assembled on the outer shell, the outer shell is placed on the base 411, and the chain assembly 41 transfers the base 411 to the assembly mechanism 42. The manipulator 11 cooperates with the assembly mechanism 42 to assemble the ignition coil. Subsequently, the chain assembly 41 moves the base 411 with the ignition coil to the high and low voltage detection mechanism 43 for high and low voltage detection. In this way, the processing process has a high degree of automation, good quality and consistency, and low labor costs.
