Description

Technical Field

[0001] This utility model relates to the field of ignition coil manufacturing technology, specifically a performance testing device for electronic fuel injection ignition coils. Background Technology

[0002] The core function of an ignition coil for electronic fuel injection is to convert low voltage into high voltage, providing sufficient energy to the spark plug to ignite the air-fuel mixture. During the production process of the ignition coil, in order to ensure that the ignition coil can work properly, a testing device is needed to conduct an electrical test on it.

[0003] However, the existing testing devices typically expose their testing components to the inside of the testing workshop, where there is usually floating dust. Once this dust comes into contact with the testing components, it will affect the operating accuracy of the testing device. Therefore, in order to address the above problem, a performance testing device for ignition coils used in electronic fuel injection is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The utility model provides a performance testing device for an electronically controlled ignition coil, comprising a workbench, a pulley rotatably connected to the inner side of the workbench, a belt rotatably connected to the outer side of the pulley, a first motor fixedly connected to the outer side of the workbench, a pulley on one side fixedly connected to the output end of the first motor, a movable frame fixedly connected to the outer side of the belt, a lifting frame slidably connected to the inner side of the movable frame, a positioning groove formed on the surface of the lifting frame, a hydraulic cylinder fixedly connected to the inner side of the workbench, a push plate fixedly connected to the output end of the hydraulic cylinder, a glass cover fixedly connected to the outer side of the workbench, an electrical detection component fixedly connected to the inner side of the glass cover, an air filter connected to one side of the glass cover, and a fan connected to the other side of the glass cover. The process involves setting up a push plate, glass cover, air filter, and fan. A positioning groove is created based on the shape of the ignition coil to hold it in place. The ignition coil is inserted into the positioning groove for positioning and limiting, ensuring that the energized end of the ignition coil faces upwards after positioning. A belt moves to move the moving frame, lifting frame, and the ignition coil inside to align with the energization detection component. The push plate rises, moving the lifting frame and the ignition coil inside to the inside of the glass cover. Air is then drawn out by the fan and filtered through the air filter to remove dust. The ignition coil is then raised further, aligning with the energization detection component for energization testing. After testing, the ignition coil is pulled out, and qualified and unqualified ignition coils are placed separately, ensuring that dust does not easily affect the device's detection accuracy.

[0006] Preferably, the workbench surface has a discharge groove, a support plate is slidably connected to the inner side of the discharge groove, and a cylinder is fixedly connected to the outer side of the workbench. The output end of the cylinder is fixedly connected to the support plate. This step, by setting up the discharge groove, support plate, and cylinder, allows the lifting frame and the ignition coil inside it to move to the upper side of the support plate after the ignition coil is tested, driven by a belt. The cylinder then moves the support plate away from the ignition coil, allowing the ignition coil to fall through the positioning groove and discharge groove under the influence of gravity. This eliminates the need for the user to manually remove the tested ignition coil. After the tested coil is discharged, the support plate can be moved back to its original position, allowing untested ignition coils to be placed back into the positioning groove. This prevents untested ignition coils from falling when moving through the upper side of the discharge groove to align with the glass cover. Furthermore, this eliminates the need to manually remove the tested ignition coils after testing and prevents untested ignition coils from falling from the discharge groove, making the unloading of the device after testing more convenient and improving its practicality.

[0007] Preferably, a discharge pipe is connected to the lower side of the workbench, and a second motor is fixedly connected to the outer side of the discharge pipe. A guide plate is fixedly connected to the output end of the second motor. A sorting groove is opened on one side surface of the discharge pipe, and the guide plate and the sorting groove are used in conjunction. In this step, by setting up a discharge pipe, a second motor, a guide plate, and a sorting groove, when a defective ignition coil falls through the discharge groove, the guide plate is rotated to enter the inner side of the sorting groove, so that the defective ignition coil falls on the upper side of the guide plate and is discharged through the sorting groove. When a qualified ignition coil falls, the guide plate is rotated to move away from the inner side of the discharge pipe, and the ignition coil is discharged from the lower opening of the discharge pipe. This achieves the sorting and discharge of defective and qualified ignition coils, making it less likely for them to mix during discharge and improving the convenience of material sorting of the device.

[0008] Preferably, a limiting frame is fixedly connected to the outer side of the workbench, and one end of the movable frame is slidably connected to the limiting frame. This step, by setting the limiting frame, allows the upper and lower sides of one end of the movable frame to be tightly limited by the groove on the surface of the limiting frame when the movable frame moves, thereby making the movement of the movable frame more stable and improving the stability of the device.

[0009] Preferably, a limiting plate is fixedly connected to one end of the movable frame, and the limiting plate and the limiting frame are slidably connected. This step, by setting the limiting plate, ensures that when the movable frame moves, one side of the limiting plate is in close contact with one side of the limiting frame, thereby making the movable frame less prone to shaking due to friction with the limiting frame, making the movement of the movable frame more stable and improving the stability of the device.

[0010] Preferably, a mounting plate is fixedly connected to the outer side of the workbench, and a mounting groove is formed on the surface of the mounting plate. This step, by setting up the mounting plate and the mounting groove, allows the device to be installed and fixed by screwing screws into the mounting groove and the mounting location, thereby improving the convenience of device installation.

[0011] The advantages of this utility model are:

[0012] 1. This utility model uses a push plate, a glass cover, an air filter, and a fan. A positioning groove is created based on the shape of the ignition coil to hold it in place. The ignition coil is inserted into the positioning groove and limited, ensuring that the energized end of the ignition coil faces upwards after being positioned. A belt moves to move the moving frame, lifting frame, and the ignition coil inside to align with the energization detection component. The push plate rises, causing the lifting frame and the ignition coil inside to move inside the glass cover. Air is then drawn out by the fan and filtered through the air filter to remove dust. The ignition coil is then raised to align with the energization detection component for energization testing. After testing, the ignition coil is pulled out, and qualified and unqualified ignition coils are placed separately, ensuring that dust does not easily affect the device's detection accuracy.

[0013] 2. This utility model, by setting up a discharge groove, a support plate, and a cylinder, allows the ignition coil to be moved to the upper part of the support plate after testing by a belt-driven lifting frame and the ignition coil inside it. The cylinder then moves the support plate away from the ignition coil, allowing the ignition coil to fall through the positioning groove and discharge groove under the influence of gravity. This eliminates the need for the user to manually remove the tested ignition coil. After the tested coil is discharged, the support plate can be moved back to its original position, allowing untested ignition coils to be placed back into the positioning groove. This prevents untested ignition coils from falling off when moving through the discharge groove to align with the glass cover. Furthermore, this design eliminates the need for manual removal of tested ignition coils and prevents untested ignition coils from falling from the discharge groove, making post-test unloading more convenient and improving the device's practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5As shown, a performance testing device for an electronic fuel injection ignition coil includes a workbench 1. A pulley 2 is rotatably connected to the inner side of the workbench 1, and a belt 3 is rotatably connected to the outer side of the pulley 2. A first motor 4 is fixedly connected to the outer side of the workbench 1. One side of the pulley 2 and the output end of the first motor 4 are fixedly connected. A movable frame 5 is fixedly connected to the outer side of the belt 3. A lifting frame 6 is slidably connected to the inner side of the movable frame 5. A positioning groove 7 is formed on the surface of the lifting frame 6. A hydraulic cylinder 8 is fixedly connected to the inner side of the workbench 1. A push plate 9 is fixedly connected to the output end of the hydraulic cylinder 8. A glass cover 10 is fixedly connected to the outer side of the workbench 1. An electrical detection component 11 is fixedly connected to the inner side of the glass cover 10. An air filter 12 is connected to one side of the glass cover 10, and a fan 13 is connected to the other side of the glass cover 10. This step involves setting the push plate 9... The device consists of a glass cover 10, an air filter 12, and a fan 13. A positioning groove 7 is provided to hold the ignition coil in place. The ignition coil is inserted into the positioning groove 7 and positioned to ensure that the energized end of the ignition coil faces upwards. The belt 3 moves to move the moving frame 5, the lifting frame 6, and the ignition coil inside it to align with the energization detection component 11. The push plate 9 is raised, causing the lifting frame 6 and the ignition coil inside it to move inside the glass cover 10. The fan 13 then draws out air, which is filtered through the air filter 12 to remove dust. The ignition coil is then raised to align with the energization detection component 11 for energization testing. After testing, the ignition coil is pulled out, and qualified and unqualified ignition coils are placed separately, ensuring that dust does not easily affect the device's testing accuracy.

[0024] Furthermore, such as Figure 1 and Figure 2As shown, the workbench 1 has a discharge groove 101 on its surface. A support plate 14 is slidably connected to the inner side of the discharge groove 101, and a cylinder 15 is fixedly connected to the outer side of the workbench 1. The output end of the cylinder 15 is fixedly connected to the support plate 14. This step, by setting up the discharge groove 101, the support plate 14, and the cylinder 15, ensures that after the ignition coil is tested, the belt 3 drives the lifting frame 6 and the ignition coil inside it to move to the upper side of the support plate 14. The cylinder 15 then drives the support plate 14 to move away from the ignition coil, allowing the ignition coil to pass through the positioning groove 7 and be discharged under the influence of gravity. The slot 101 is lowered, eliminating the need for the user to manually remove the tested ignition coil. After the tested coil is discharged, the support plate 14 can be moved back into place, allowing the untested ignition coil to be placed back into the positioning slot 7. This prevents the untested ignition coil from falling off when it moves over the discharge slot 101 and aligns with the glass cover 10. Consequently, the tested ignition coil does not need to be manually removed after testing, and the untested ignition coil will not fall off the discharge slot 101. This makes the unloading of the device after testing more convenient and improves the practicality of the device.

[0025] Furthermore, such as Figure 1 and Figure 4 As shown, a discharge pipe 16 is connected to the lower side of the workbench 1. A second motor 17 is fixedly connected to the outer side of the discharge pipe 16. A guide plate 18 is fixedly connected to the output end of the second motor 17. A sorting groove 19 is opened on one side surface of the discharge pipe 16. The guide plate 18 and the sorting groove 19 are used in conjunction. In this step, by setting up the discharge pipe 16, the second motor 17, the guide plate 18, and the sorting groove 19, when a defective ignition coil falls through the discharge groove 101, the guide plate 18 is rotated to enter the inner side of the sorting groove 19, so that the defective ignition coil falls on the upper side of the guide plate 18 and is discharged through the sorting groove 19. When a qualified ignition coil falls, the guide plate 18 is rotated to move away from the inner side of the discharge pipe 16, and the ignition coil is discharged from the lower opening of the discharge pipe 16. This achieves the sorting and discharge of defective and qualified ignition coils, making it less likely for them to mix during discharge and improving the convenience of material sorting of the device.

[0026] Furthermore, such as Figure 1 and Figure 5 As shown, a limiting frame 20 is fixedly connected to the outer side of the workbench 1, and one end of the movable frame 5 is slidably connected to the limiting frame 20. This step, by setting the limiting frame 20, ensures that when the movable frame 5 moves, the groove on the surface of the limiting frame 20 tightly limits the upper and lower sides of one end of the movable frame 5, thereby making the movement of the movable frame 5 more stable and improving the stability of the device.

[0027] Furthermore, such as Figure 1 and Figure 5As shown, a limiting plate 21 is fixedly connected to one end of the movable frame 5, and the limiting plate 21 and the limiting frame 20 are slidably connected. This step, by setting the limiting plate 21, ensures that when the movable frame 5 moves, one side of the limiting plate 21 is in close contact with the side of the limiting frame 20, thereby making the movable frame 5 less prone to shaking due to friction with the limiting frame 20, making the movement of the movable frame 5 more stable and improving the stability of the device.

[0028] Furthermore, such as Figure 1 As shown, a mounting plate 22 is fixedly connected to the outer side of the workbench 1, and a mounting groove 23 is provided on the surface of the mounting plate 22. This step, by setting the mounting plate 22 and the mounting groove 23, allows the device to be installed and fixed by screwing the screws into the mounting groove 23 and the mounting location, thereby improving the convenience of device installation.

[0029] The working principle is as follows: A positioning groove 7 is created based on the shape of the ignition coil to hold it in place. The ignition coil is inserted into the positioning groove 7 and limited, ensuring that the energized end of the ignition coil faces upwards after being positioned. The first motor 4 drives the pulley 2 to rotate, which in turn drives the belt 3 to move. The movement of the belt 3 moves the moving frame 5, the lifting frame 6, and the ignition coil inside it until they are aligned with the energization detection component 11. The hydraulic cylinder 8 drives the push plate 9 to rise, which moves the lifting frame 6 and the ignition coil inside it to the inside of the glass cover 10. Air is then drawn out by the fan 13 and filtered through the air filter 12 to remove dust. The ignition coil is then raised further, allowing it to connect with the energization detection component 11 for energization detection. After testing, the ignition coil is pulled out. Then, the movement of belt 3 drives the moving frame 5, lifting frame 6, and the ignition coil inside to the upper side of support plate 14. Cylinder 15 drives support plate 14 to move away from ignition coil, so that ignition coil falls through positioning groove 7 and discharge groove 101 under the influence of gravity, and enters the inner side of discharge pipe 16. When the ignition coil is unqualified, the second motor 17 drives guide plate 18 to rotate, so that guide plate 18 enters the inner side of sorting groove 19, so that unqualified ignition coil falls on the upper side of guide plate 18 and is discharged through sorting groove 19. When the ignition coil is qualified, guide plate 18 is rotated away from the inside of discharge pipe 16, so that ignition coil is discharged from the lower opening of discharge pipe 16, so that qualified ignition coil and unqualified ignition coil can be placed separately.
