Description

Technical Field

[0001] This invention relates to the field of ignition coil technology, and in particular to an ignition coil assembly device. Background Technology

[0002] The ignition coil is a key component of the engine. It includes a housing, an electromagnetic assembly, a circuit board, and other parts. The housing has cylindrical terminals. The high-voltage output of the secondary coil assembly of the electromagnetic assembly is electrically connected to the terminals via contacts. During ignition coil manufacturing, the contacts are typically bent first, and then the electromagnetic assembly is placed in the mounting cavity of the housing, with the contacts resting against the end face of the terminals. To save material and improve the reliability of the electrical connection between the contacts and terminals, the design length of the contacts is readjusted. Currently, ignition coils are typically produced using a combination of equipment and manual labor. This can easily result in the bending angle θ of the contacts being too large or too small. If the bending angle θ is too small, the end of the contact will be suspended above the end face of the terminal; if the bending angle θ is too large, the end of the contact will rest against the outer surface of the terminal. Both situations are abnormal and unqualified, resulting in a low yield rate for ignition coils, low production efficiency, and low automation. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an ignition coil assembly device that can ensure normal contact between the contacts and the terminals, thereby improving the yield and assembly efficiency of the ignition coil.

[0004] An ignition coil assembly apparatus according to an embodiment of the present invention includes: a frame with a first conveying mechanism; a resistance testing device including a tester and a first clamping fixture disposed on the frame, the first clamping fixture being used to clamp a secondary coil assembly having two secondary pins, one of the secondary pins being electrically connected to a contact piece, the tester including two sets of probes, the two sets of probes being respectively configured to electrically connect the other secondary pin of the secondary coil assembly and the contact piece; and a bending device including a second clamping fixture, a first linear drive mechanism, and an actuator, the second clamping fixture and the first linear drive mechanism being... All linear drive mechanisms are mounted on the frame. The first transport mechanism is configured to transport the secondary coil assembly from the first clamping fixture to the second clamping fixture, with the axis of the secondary coil assembly parallel to the horizontal direction and the contact piece in a vertical state. The output end of the first linear drive mechanism is connected to the actuator. The first linear drive mechanism is configured to drive the actuator to move along the axis of the secondary coil assembly, so that the actuator bends the vertical contact piece to an inclined state, and the angle θ between the contact piece and the axis of the secondary coil assembly is a preset angle.

[0005] It has at least the following beneficial effects: The first linear drive mechanism drives the actuator to move along the axis of the secondary coil assembly, bending the vertical contact to an inclined state. This ensures a high degree of consistency and uniformity of the angle θ between the contact and the axis of the secondary coil assembly in ignition coils produced in the same or different batches. This effectively eliminates the angle dispersion problems caused by manual bending or outdated equipment, stably controlling the angle θ within the tolerance range required by the process, significantly improving the first-pass yield of the ignition coil in this critical assembly dimension. A uniform and qualified angle θ is a key prerequisite for ensuring stable and reliable elastic contact between the contact and the terminal after assembly, avoiding problems such as increased resistance, insufficient discharge energy, or signal transmission failure due to poor contact. The ignition coil assembly equipment fundamentally solves the control problem of the critical quality attribute of the 20° contact angle, significantly improving the overall yield of the final ignition coil product. Simultaneously, the ignition coil assembly equipment integrates resistance testing, bending forming, and appearance inspection into an automated process, replacing traditional multi-station, manual, or semi-automatic operations, greatly improving production efficiency and process stability.

[0006] According to some embodiments of the present invention, a first imaging module is further included, the first imaging module being configured to acquire images of the periphery of the secondary coil assembly transported onto the second clamping fixture, and to capture images of the secondary coil assembly and the contact piece in a direction parallel to the plane where the contact piece is located.

The shooting directions of the first camera and the second camera are both horizontal and perpendicular to each other. The shooting direction of the first camera is perpendicular to the driving direction of the first linear drive mechanism. The second clamping fixture is rotatably connected to the frame. The second clamping fixture is configured to rotate 180° around the vertical axis each time, so that the first camera and the second camera can capture images of the periphery of the secondary coil assembly, and the first camera can capture images of the secondary coil assembly and the contact piece in a direction parallel to the plane where the contact piece is located.

[0008] According to some embodiments of the present invention, a positioning device is further included, the positioning device comprising a second linear drive mechanism, a limiting member and a positioning member, the positioning member being disposed on the second clamping fixture, the second linear drive mechanism being connected to the limiting member to drive the limiting member to move so that the limiting member engages with the positioning member, the contact piece on the second clamping fixture having a surface, the normal of the surface being coplanar with the driving direction of the first linear drive mechanism.

[0009] According to some embodiments of the present invention, the limiting member is provided with a U-shaped groove, and the positioning member is four limiting posts provided on the second clamping fixture. The four limiting posts are distributed at the four corners and form a limiting groove for limiting the secondary coil assembly. The limiting member is engaged with two adjacent limiting posts through the U-shaped groove so that the normal of the surface is coplanar with the driving direction of the first linear drive mechanism.

[0010] According to some embodiments of the present invention, the actuator is a rotating wheel.

The inner surfaces of the two C-shaped irons near the first end face abut against the end face of the magnetic core away from the T-shaped iron. The second end faces of the two C-shaped irons abut against the two opposing sides of one end of the T-shaped iron. One end of the T-shaped iron and the two C-shaped irons form a loop structure to obtain an electromagnetic assembly.

[0018] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0019] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0020] like Figure 1 and Figure 2 As shown, the present invention discloses an ignition coil, including a secondary coil assembly 10, a contact piece 20, a T-shaped iron 30, a primary coil assembly 40, a magnetic core 50, a housing 70, a control circuit board 80, and two C-shaped irons 60. The primary coil assembly 40 has a first central hole 41 extending along its axis. The first central hole 41 is a stepped through hole. The T-shaped iron 30 passes through the first central hole 41. One end of the T-shaped iron 30 passes through the first central hole 41 and extends to the outside of the primary coil assembly 40. The other end of the T-shaped iron 30 abuts against the stepped surface of the stepped through hole. The magnetic core 50 passes through the first central hole 41. The magnetic core 50 has two opposite end faces. The end face of the magnetic core 50 near the T-shaped iron 30 abuts against the end face of the T-shaped iron 30 (the end face of the other end of the T-shaped iron 30). The T-shaped iron 30, the primary coil assembly 40, and the magnetic core 50 form a primary assembly. The secondary coil assembly 10 has a second central hole 11 extending along its axis. The secondary coil assembly 10 has two secondary pins, one of which (high-voltage output terminal) is electrically connected to a contact 20, which is fixed to the secondary coil assembly 10. The primary assembly passes through the second central hole 11, and one end of the T-shaped iron 30 extends outside the secondary coil assembly 10. The first end faces of the two C-shaped irons 60 abut against each other. The inner surfaces of the two C-shaped irons 60 near their first end faces abut against the end face of the magnetic core 50 away from the T-shaped iron 30. The second end faces of the two C-shaped irons 60 abut against the two ends of one end of the T-shaped iron 30. On opposite sides, two C-shaped iron pieces 60 are secured to the secondary coil assembly 10. One end of the T-shaped iron piece 30 and the two C-shaped iron pieces 60 form a loop structure. The secondary coil assembly 10, the primary assembly, and the two C-shaped iron pieces 60 form an electromagnetic assembly. The axis of the secondary coil assembly 10 and the two C-shaped iron pieces 60 are coplanar. The housing 70 has a mounting position and a terminal 71. The electromagnetic assembly is assembled in the mounting position of the housing 70, and the contact piece 20 abuts against the end face of the terminal 71 of the housing 70. The control circuit board 80 is mounted in the housing 70, and the pins of the control circuit board 80 are electrically connected to the primary pins of the primary coil assembly 40. The secondary coil assembly 10 includes a secondary frame and a secondary coil. A second central hole 11 is opened in the middle of the secondary frame. Multiple positioning slots are opened on the secondary frame, and the secondary coil is wound in the multiple positioning slots. The structure of the primary coil assembly 40 is similar to that of the secondary coil assembly 10. The other structures and working principles of the ignition coil are known and will not be described redundantly here.

[0021] Understandably, the ignition coil is installed on the engine. The engine control unit (ECU) sends an ignition command to the control circuit board 80, which turns on the power switch inside the control circuit board 80, allowing the low-voltage current (usually 12V) of the battery to flow through the primary coil of the primary coil assembly 40. That is, a primary current is formed in the primary coil. The primary current generates an enhanced magnetic field that is mainly distributed along the path of the T-shaped iron 30, the magnetic core 50, the C-shaped iron 60 and the T-shaped iron 30. Energy is stored in the form of the magnetic field. When ignition is required, the power switch in the ECU command control circuit board 80 is suddenly cut off, the primary current is quickly interrupted, causing the enhanced magnetic field it establishes to decay instantaneously. The rapidly changing magnetic field passes through the secondary coil assembly 10, and according to the law of electromagnetic induction (Faraday's law), an extremely high pulse voltage (up to tens of thousands of volts) is induced at both ends of the secondary coil of the secondary coil assembly 10. This pulse voltage is conducted to the terminal 71 through the contact 20, and the high voltage is output from the terminal 71, directly or through a very short high voltage wire to the center electrode of the spark plug. The extremely high pulse voltage breaks down the gap between the spark plug electrodes, generating a strong electric spark, igniting the combustible mixture in the engine cylinder.

[0022] The high-permeability closed magnetic circuit formed by the T-shaped iron 30, the magnetic core 50, and the two C-shaped irons 60 greatly constrains and concentrates the magnetic field lines, enabling the magnetic field generated by the primary coil to be coupled to the secondary coil more effectively, thereby improving the energy conversion efficiency and ensuring that a sufficiently high ignition voltage is generated.

[0023] like Figures 3 to 6 As shown, this invention discloses an ignition coil assembly device, including a frame 100, a resistance testing device 200, a bending device 300, and a first photographing module 400. A first transport mechanism 110 is provided on the frame 100. Figure 4 As shown, the resistance testing device 200 includes a tester and a first clamping fixture 210 mounted on a frame 100. The first clamping fixture 210 is used to clamp the secondary coil assembly 10, such as... Figure 2 As shown, the secondary coil assembly 10 has two secondary pins, one of which is connected to a contact 20, as shown. Figure 4 As shown, the tester includes two sets of probes 220, which are respectively configured to electrically connect to another secondary pin and contact 20 of the secondary coil assembly 10; as Figure 5 and Figure 6As shown, the bending device 300 includes a second clamping fixture 310, a first linear drive mechanism 320, and an actuator 330. The second clamping fixture 310 and the first linear drive mechanism 320 are both mounted on the frame 100. The first transport mechanism 110 is configured to transport the secondary coil assembly 10 on the first clamping fixture 310 to the second clamping fixture 310, and to make the axis of the secondary coil assembly 10 parallel to the horizontal direction and the contact piece 20 in a vertical state. The output end of the first linear drive mechanism 320 is connected to the actuator 330. The first linear drive mechanism 320 is configured to drive the actuator 330 to move along the axial direction of the secondary coil assembly 10, so that the actuator 330 bends the vertical contact piece 20 to an inclined state, and makes the angle θ between the contact piece 20 and the axis of the secondary coil assembly 10 a preset angle.

[0024] like Figure 3 As shown, the first imaging module 400 is configured to acquire images of the periphery of the secondary coil assembly 10 transported onto the second clamping fixture 310, and to capture images of the secondary coil assembly 10 and the contact 20 in a direction parallel to the plane where the contact piece 20 is located.

[0025] Initially, the two sets of probes 220 avoid the first clamping fixture 210, and the actuator 330 is positioned to avoid the second clamping fixture 310. The secondary coil assembly 10 is placed on the first clamping fixture 210, which clamps the secondary coil assembly 10. Both sets of probes 220 move towards the first clamping fixture 210, so that the two sets of probes 220 respectively abut against another secondary pin and contact 20 of the secondary coil assembly 10. The two sets of probes 220 achieve electrical connection to the other secondary pin and contact 20 of the secondary coil assembly 10, and the tester can test the electrical characteristics of the secondary coil assembly 10, such as resistance, thereby determining whether the secondary coil assembly 10 is qualified.

[0026] When the secondary coil assembly 10 is determined to be a qualified product, the first conveying mechanism 110 conveys the qualified secondary coil assembly 10 from the first clamping fixture 210 to the second clamping fixture 310. The second clamping fixture 310 clamps the secondary coil assembly 10 such that the axis of the secondary coil assembly 10 is parallel to the horizontal direction and the contact piece 20 is in a vertical state. Then, the actuator 330 bends the vertical contact piece 20 to an inclined state. In the inclined state, the contact piece 20 forms an angle θ with the axis of the secondary coil assembly 10 (e.g., ...). Figure 2 As shown), the corner forming of the contact piece 20 is completed.

[0027] Next, the first imaging module 400 acquires a panoramic image of the periphery of the secondary coil assembly 10, and acquires a side view image of the secondary coil assembly 10 and the contact 20 along a direction parallel to the plane where the contact piece 20 is located. By comparing the panoramic image and the side view image with the qualified sample image, the appearance inspection and the included angle θ inspection are completed to determine whether the following items are qualified: appearance of the contact piece 20: including the surface condition, shape, length, and overall morphology of the contact piece 20; appearance of the connection point between the secondary pin and the contact piece 20: including solder joint fullness, cold solder joint defects, and cold solder joint defects; and the value of the included angle θ between the contact piece 20 and the axis of the secondary coil assembly 10.

[0028] Based on the above judgment results, a comprehensive assessment is made: whether the electrical connection quality between the secondary pin and the contact 20 is qualified; whether the bending angle (angle θ) and shape of the contact 20 are qualified; and whether there are any defects such as slot crossing defects in the secondary coil winding on the secondary coil assembly 10. Thus, an integrated inspection of the component's appearance, key dimensions, and assembly quality is completed simultaneously.

[0029] The actuator 330 of the ignition coil assembly equipment bends the vertical contact 20 to an inclined state, ensuring a high degree of consistency and uniformity in the angle θ between the contact 20 and the axis of the secondary coil assembly 10 in ignition coils produced in the same batch or even different batches. This effectively eliminates the angle dispersion problems caused by manual bending or old equipment, stably controlling the angle θ within the tolerance range required by the process, and significantly improving the first-pass yield of the ignition coil in this critical assembly dimension. A uniform and qualified angle θ is a key prerequisite for ensuring a stable and reliable elastic contact between the contact 20 and the terminal 71 after assembly. This directly avoids problems such as increased resistance, insufficient discharge energy, or signal transmission failure caused by poor contact. The ignition coil assembly equipment fundamentally solves the control problem of the key quality attribute of the contact 20 angle, significantly improving the overall yield of the final ignition coil product. At the same time, the automated process of the ignition coil assembly equipment, which integrates resistance testing, bending forming, and appearance inspection, replaces traditional multi-station, manual, or semi-automatic operations, greatly improving production efficiency and process stability.

[0030] Understandably, the ignition coil assembly equipment also includes a control system. The control system processes the images acquired by the first imaging module 400, compares the detected images with images of qualified samples, and thus obtains the detection results. The ignition coil assembly equipment also includes a first defective product unloading device and a second defective product unloading device. The first defective product unloading device is located next to the first clamping fixture 210. After the tester completes the inspection of the secondary coil assembly 10, the first defective product unloading device unloads the secondary coil assembly 10 that failed the test from the first clamping fixture 210. The second defective product unloading device is located next to the second clamping fixture 310. After the appearance inspection of the secondary coil assembly 10 is completed, the second defective product unloading device unloads the secondary coil assembly 10 that fails the appearance inspection from the second clamping fixture 310.

[0031] like Figure 2 As shown, the contact piece 20 has a surface 21 parallel to the plane in which the contact piece 20 is located, and the normal of the surface 21 is coplanar with the axis of the secondary coil assembly 10. When the contact piece 20 is in a vertical state, the surface 21 of the contact piece 20 is perpendicular to the axis of the secondary coil assembly 10; when the contact piece 20 is in an inclined state, the surface 21 of the contact piece 20 forms an angle θ with the axis of the secondary coil assembly 10.

[0032] like Figure 5 or Figure 6 As shown, the output end of the first linear drive mechanism 320 is connected to the actuator 330. The first linear drive mechanism 320 is configured to drive the actuator 330 to move along the axial direction of the secondary coil assembly 10 and pass above the second clamping fixture 310. Initially, the first linear drive mechanism 320 drives the actuator 330 to move to avoid the position of the second clamping fixture 310. After the second clamping fixture 310 clamps the secondary coil assembly 10, the first linear drive mechanism 320 drives the actuator 330 to move. The actuator 330 moves along the axial direction of the secondary coil assembly 10 and passes above the second clamping fixture 310. The actuator 330 pushes the surface 21 of the contact piece 20, bending the vertical contact piece 20 to an inclined state.

[0033] The first linear drive mechanism 320 is connected to the frame 100. The output end of the first linear drive mechanism 320 is connected to the actuator 330. The height of the actuator 330 is higher than that of the secondary coil assembly 10, and the actuator 330 is directly opposite the contact piece 20.

[0034] like Figure 5As shown, in some embodiments, the first camera module 400 includes a first camera 410 and a second camera 420 both mounted on the frame 100. The shooting directions of the first camera 410 and the second camera 420 are both horizontal and perpendicular to each other. The shooting direction of the first camera 410 is perpendicular to the driving direction of the first linear drive mechanism 320. The second clamping fixture 310 is rotatably connected to the frame 100 and is configured to rotate 180° around the vertical axis each time. When the second clamping fixture 310, carrying the secondary coil assembly 10, is positioned on the frame 100, the first camera 410 and the second camera 420 can capture images of the two sides of the secondary coil assembly 10. The first and second images are captured, and then the second clamping fixture 310 rotates 180° around the vertical axis. The first camera 410 and the second camera 420 can capture the third and fourth images of the secondary coil assembly 10 in the other two directions. The first image, the second image, the third image and the fourth image constitute the appearance of the secondary coil assembly 10 and the contact 20. That is, the first camera 410 and the second camera 420, together with the second clamping fixture 310, rotate 180° around the vertical axis once, and can capture a panoramic image of the periphery of the secondary coil assembly 10 and the contact 20. Along the direction parallel to the plane where the contact 20 is located, a side view image of the secondary coil assembly 10 and the contact 20 is obtained.

[0035] The first camera module 400 also includes multiple fill lights 430, which are all connected to the frame 100 and distributed around the second clamping fixture 310. The multiple fill lights 430 provide supplementary lighting to the secondary coil assembly 10 on the second clamping fixture 310, thereby improving the image acquisition effect of the first camera 410 and the second camera 420.

[0036] like Figure 3 As shown, in some embodiments, the ignition coil assembly apparatus further includes a positioning device 500, such as... Figure 5 and Figure 6 As shown, the positioning device 500 is used to fix the second clamping fixture 310, prevent the second clamping fixture 310 from rotating unexpectedly, ensure that when the first linear drive mechanism 320 drives the actuator 330 to move, the actuator 330 can move along the axial direction of the secondary coil assembly 10 and pass above the second clamping fixture 310, and ensure that the first camera 410 and the second camera 420 can capture the first image, the second image, the third image and the fourth image.

[0037] The positioning device 500 includes a second linear drive mechanism 510, a limiting member 520, and a positioning member 530. The positioning member 530 is disposed on the second clamping fixture 310. The second linear drive mechanism 510 is connected to the frame 100. The output end of the second linear drive mechanism 510 is connected to the limiting member 520. The second linear drive mechanism 510 drives the limiting member 520 to move on the horizontal plane so that the limiting member 520 cooperates with the positioning member 530. When the second clamping fixture 310 is fixed on the frame 100, the normal of the surface 21 is coplanar with the driving direction of the first linear drive mechanism 320, so that the actuator 330 can push the surface 21 and bend the vertical contact piece 20 to an inclined state.

[0038] When the second linear drive mechanism 510 drives the limiting member 520 away from the positioning member 530, the second clamping fixture 310 can rotate. When the second linear drive mechanism 510 drives the limiting member 520 closer to the positioning member 530, the limiting member 520 cooperates with the positioning member 530, and the positioning device 500 fixes the second clamping fixture 310 on the frame 100.

[0039] like Figure 6 As shown, in some embodiments, the limiting member 520 is provided with a U-shaped groove, and the positioning member 530 consists of four limiting posts provided on the second clamping fixture 310. The four limiting posts are distributed at the four corners and form a limiting groove for limiting the secondary coil assembly 10. The limiting member 520 is locked outside two adjacent limiting posts through the U-shaped groove so that the normal of the surface 21 is coplanar with the driving direction of the first linear drive mechanism 320.

[0040] When the second linear drive mechanism 510 drives the limiting member 520 away from the four limiting posts, the four limiting posts exit the U-shaped groove of the limiting member 520, and the second clamping fixture 310 can rotate around the vertical axis. When the second linear drive mechanism 510 drives the limiting member 520 closer to the four limiting posts, the limiting member 520 is locked outside two of the limiting posts through the U-shaped groove. The limiting member 520 restricts the two limiting posts, preventing the second clamping fixture 310 from rotating. Then, the second linear drive mechanism 510 drives the limiting member 520 away from the four limiting posts again. The two adjacent limiting posts exit the U-shaped groove of the limiting member 520, and the second clamping fixture 310 can rotate 180° around the vertical axis. Then, the second linear drive mechanism 510 drives the limiting member 520 closer to the four limiting posts again. The limiting member 520 is locked outside the other two limiting posts through the U-shaped groove. The limiting member 520 restricts the other two limiting posts, preventing the second clamping fixture 310 from rotating again. This achieves precise 180° rotation of the second clamping fixture 310 around the vertical axis each time.

[0041] Understandably, the four limiting posts are designated as the first limiting post, the second limiting post, the third limiting post, and the fourth limiting post. These four limiting posts are distributed at the four corners. The lines connecting the first and second limiting posts, as well as the lines connecting the third and fourth limiting posts, are parallel to the first direction. The lines connecting the second and third limiting posts, as well as the lines connecting the first and fourth limiting posts, are parallel to the second direction. The first and second directions are perpendicular to each other. When the secondary coil assembly 10 is moved onto the second clamping fixture 310, the axis of the secondary coil assembly 10 is parallel to the second direction. The limiting member 520 is engaged with the first limiting post via a U-shaped groove. Outside the first and second limiting posts, the limiting member 520 restricts the first and second limiting posts, preventing the second clamping fixture 310 from rotating. Then, the second linear drive mechanism 510 drives the limiting member 520 away from the second clamping fixture 310 again, and the first and second limiting posts exit the U-shaped groove of the limiting member 520. The second clamping fixture 310 can rotate 180° around the vertical axis. Then, the second linear drive mechanism 510 drives the limiting member 520 closer to the second clamping fixture 310 again. The limiting member 520 is locked outside the third and fourth limiting posts through the U-shaped groove, restricting the third and fourth limiting posts, preventing the second clamping fixture 310 from rotating again.

[0042] The limiting post has a vertical right-angled surface, which is used to abut against one corner of the secondary coil assembly 10. A clearance space is formed between two adjacent limiting posts so that the first camera 410 and the second camera 420 can capture images of the secondary coil assembly 10 and the contact 20.

[0043] like Figure 5 or Figure 6 As shown, in some embodiments, the actuator 330 is a rotating wheel, and the output end of the first linear drive mechanism 320 is rotatably connected to the rotating wheel. The axis of the rotating wheel is perpendicular to the driving direction of the first linear drive mechanism 320, and the axis of the rotating wheel is parallel to the horizontal direction. The wheel surface is used to abut against the contact piece 20 and force the contact piece 20 to bend from a vertical state to an inclined state. Because the rotating wheel can rotate, the friction between the rotating wheel and the contact piece 20 is reduced, thereby reducing the risk of wear on the contact piece 20.

[0044] Understandably, the rotating wheel rests against the surface 21 of the contact piece 20.

[0045] The second clamping fixture 310 includes a rotating plate and a rotary drive mechanism. The rotary drive mechanism is fixedly connected to the frame 100. The output end of the rotary drive mechanism faces upward and is connected to the rotating plate. The rotary drive mechanism is used to drive the rotating plate to rotate in the horizontal plane. Four limiting posts are all connected to the upper surface of the rotating plate. The axis of the limiting groove formed by the four limiting posts is coaxial with the rotation axis of the rotating plate.

[0046] like Figure 4 As shown, the resistance testing device 200 also includes two third linear drive mechanisms 230, each mounted on the frame 100. The outputs of the two third linear drive mechanisms 230 are respectively connected to two sets of probes 220. The third linear drive mechanisms 230 drive the probes 220 to move closer to or further away from the first clamping fixture 210, so that the two sets of probes 220 can respectively abut against the secondary pins and contacts 20 of the secondary coil assembly 10, thereby enabling the two sets of probes 220 to be electrically connected to the secondary pins and contacts 20 of the secondary coil assembly 10.

[0047] like Figure 7 As shown, in some embodiments, the ignition coil assembly apparatus further includes an electromagnetic component assembly device 600, such as... Figure 2 As shown, the electromagnetic component assembly device 600 is used to insert a T-shaped iron 30 into the first central hole 41 of the primary coil assembly 40, with one end of the T-shaped iron 30 passing through the first central hole 41 and extending outside the primary coil assembly 40. A magnetic core 50 is inserted into the first central hole 41 and placed on the other end face of the T-shaped iron 30 to obtain a primary assembly. The primary assembly is then inserted into the second central hole 11 of the secondary coil assembly 10, with one end of the T-shaped iron 30 extending outside the secondary coil assembly 10 to obtain a secondary assembly. The sides of the first ends of two C-shaped irons 60 are placed against the end face of the magnetic core 50 away from the T-shaped iron 30, and the second end faces of the two C-shaped irons 60 are placed against two opposing sides of one end of the T-shaped iron 30. One end of the T-shaped iron 30 and the two C-shaped irons 60 form a loop shape to obtain the electromagnetic component.

[0048] like Figure 7 As shown, in some embodiments, the ignition coil assembly equipment further includes a semi-finished product assembly device 700, such as... Figure 2 As shown, the semi-finished product assembly device 700 is used to assemble the electromagnetic components into the mounting position of the housing 70, and the contact piece 20 abuts against the end face of the terminal 71 of the housing 70, the control circuit board 80 is mounted on the housing 70, and the pins of the control circuit board 80 are electrically connected to the primary pins of the primary coil assembly 40 to obtain the semi-finished product.

[0049] like Figure 7 and Figure 8As shown, the ignition coil assembly equipment also includes a welding device 120, a second photographing module 130, a performance testing device 140, and a finished product stacking device 150. The welding device 120 is used to weld the pins of the control circuit board 80 to the primary pins of the primary coil assembly 40 to obtain the finished product. The second photographing module 130 is used to take pictures of the finished product to obtain images of the finished product, thereby determining whether the welding between the pins of the control circuit board 80 and the primary pins of the primary coil assembly 40 is qualified, whether the electromagnetic components are assembled in place, and whether the finished product has defects such as wear and scratches. The performance testing device 140 is used to test whether the ignition performance of the finished product is qualified. The finished product stacking device 150 is used to stack the finished products that are determined to be qualified by the performance testing device 140, thereby completing the unloading and packaging of qualified finished products.

[0050] like Figure 9 As shown, in some embodiments, the electromagnetic component assembly device 600 includes a primary coil component conveyor belt 610, a primary coil component feeding mechanism 620, a T-shaped iron feeding mechanism 630, a magnetic core feeding mechanism 640, a first assembly fixture 651, a second transport mechanism 660, a first assembly mechanism 650, a third transport mechanism 670, a C-shaped iron feeding mechanism 680, and a second assembly mechanism 690, all mounted on the frame 100.

[0051] Multiple primary coil assembly clamps are evenly distributed on the primary coil assembly conveyor belt 610. The primary coil assembly feeding mechanism 620, the T-shaped iron feeding mechanism 630, and the magnetic core feeding mechanism 640 are all located beside the primary coil assembly conveyor belt 610, and the primary coil assembly feeding mechanism 620, the T-shaped iron feeding mechanism 630, and the magnetic core feeding mechanism 640 are distributed along the conveying direction of the primary coil assembly conveyor belt 610.

[0052] The primary coil assembly feeding mechanism 620 is used to feed the primary coil assembly 40 into the primary coil assembly fixture. The T-shaped iron feeding mechanism 630 is used to feed the T-shaped iron 30 into the first center hole 41 of the primary coil assembly 40 on the primary coil assembly fixture. That is, one end of the T-shaped iron 30 is inserted into the first center hole 41 from one end, and one end of the T-shaped iron 30 extends to the other end of the first center hole 41. The magnetic core feeding mechanism 640 is used to feed the magnetic core 50 into the first center hole 41 of the primary coil assembly 40 on the primary coil assembly fixture and place it on the other end face of the T-shaped iron 30. That is, the magnetic core 50 is inserted into the first center hole 41, so that the end face of the magnetic core 50 abuts against the other end face of the T-shaped iron 30. Under the action of magnetic force, the T-shaped iron 30 and the magnetic core 50 are connected together to obtain the primary assembly.

[0053] After the secondary coil assembly 10 undergoes visual inspection and a qualified secondary coil assembly 10 is obtained, the second transport mechanism 660 transports the qualified secondary coil assembly 10 to the first assembly fixture 651. The first assembly fixture 651 is used to limit the secondary coil assembly 10. After the primary assembly is assembled from the primary coil assembly fixture on the primary coil assembly conveyor belt 610, the first assembly mechanism 650 assembles the primary assembly into the second center hole 11 of the secondary coil assembly 10 on the first assembly fixture 651 to obtain the secondary assembly. The third transport mechanism 670 then transports the secondary assembly to the second set of... The assembly mechanism 690 and the C-shaped iron feeding mechanism 680 are used to feed two C-shaped irons 60 to the second assembly mechanism 690, so that the secondary component and the two C-shaped irons 60 are simultaneously on the second assembly mechanism 690. The second assembly mechanism 690 is used to abut the first end faces of the two C-shaped irons 60, and the inner side surfaces of the two C-shaped irons 60 near the first end faces abut the end face of the magnetic core 50 away from the T-shaped iron 30. The second end faces of the two C-shaped irons 60 abut the two opposite side surfaces of one end of the T-shaped iron 30 respectively. One end of the T-shaped iron 30 and the two C-shaped irons 60 form a loop structure to obtain the electromagnetic component.

[0054] like Figure 10 As shown, the second assembly mechanism 690 includes a mounting plate 691, a pressing mechanism 692, and two fourth linear drive mechanisms 693. The mounting plate 691 is connected to the frame 100 and has a groove for limiting the secondary component. The third transport mechanism 670 is used to transport the secondary component to the groove, so that the axis of the secondary coil assembly 10 of the secondary component is horizontal. The pressing mechanism 692 is located on the mounting plate 691. After the secondary component is transported to the groove, the pressing mechanism 692 presses the secondary component down into the groove, thereby positioning the secondary component on the mounting plate 691.

[0055] Both fourth linear drive mechanisms 693 are connected to the mounting plate 691. The two fourth linear drive mechanisms 693 are arranged opposite each other. One fourth linear drive mechanism 693, the groove, and the other fourth linear drive mechanism 693 are distributed along a straight line. The output ends of both fourth linear drive mechanisms 693 are connected to C-shaped iron claws 694. The fourth linear drive mechanism 693 is used to drive the C-shaped iron claws 694 to move closer to or away from the groove in the horizontal direction. Initially, the C-shaped iron claws 694 are away from the groove. The C-shaped iron feeding mechanism 680 is used to feed two C-shaped irons 60 onto the mounting plate 691, with the two C-shaped irons 60 positioned next to the groove. Each of the two C-shaped irons 60 corresponds to a C-shaped iron gripper 694. After the two C-shaped irons 60 are on the mounting plate 691, the two C-shaped iron grippers 694 clamp the two C-shaped irons 60. Then, the fourth linear drive mechanism 693 drives the C-shaped iron grippers 694 to approach the groove in the horizontal direction, so that the two C-shaped irons 60 mate with the secondary component. This causes the first end faces of the two C-shaped irons 60 to abut against each other. The inner surfaces of the two C-shaped irons 60 near their first end faces abut against the end face of the magnetic core 50 away from the T-shaped iron 30. The second end faces of the two C-shaped irons 60 abut against two opposing sides of one end of the T-shaped iron 30.

[0056] like Figure 11 As shown, in some embodiments, the semi-finished product assembly device 700 includes a second assembly fixture 711, a housing feeding mechanism 720, a third assembly mechanism 710, a semi-finished product conveyor belt 730, a fourth handling mechanism 740, a control circuit board feeding mechanism 750, and a circuit testing mechanism 760, all of which are mounted on the frame 100.

[0057] The housing feeding mechanism 720 is used to feed the housing 70 to the second assembly fixture 711. The second assembly fixture 711 is used to clamp the housing 70 and position the housing 70. The housing 70 has an upward-facing mounting position. The third assembly mechanism 710 is used to assemble the electromagnetic component into the mounting position of the housing 70, and the contact piece 20 abuts against the end face of the terminal 71 to obtain a semi-finished product.

[0058] Multiple semi-finished product clamps are evenly distributed on the semi-finished product conveyor belt 730. The fourth conveying mechanism 740, the control circuit board loading mechanism 750, and the circuit testing mechanism 760 are distributed along the conveying direction of the semi-finished product conveyor belt 730. The fourth conveying mechanism 740 is used to transport the semi-finished products to the semi-finished product clamps. The semi-finished product clamps the semi-finished products and sequentially conveys them to the control circuit board loading mechanism 750 and the circuit testing mechanism 760. The control circuit board loading mechanism 750 is used to load the control circuit board 80 onto the shell 70 of the semi-finished product on the semi-finished product clamp, thus completing the installation of the control circuit board 80 on the shell 70, so that the pins of the control circuit board 80 abut against the primary pins of the primary coil assembly 40, thereby realizing the electrical connection between the pins of the control circuit board 80 and the primary pins of the primary coil assembly 40. Then, the circuit testing mechanism 760 is used to detect the continuity between the control circuit board 80 and the primary coil assembly 40, thereby realizing the detection of whether the electrical connection between the control circuit board 80 and the primary coil assembly 40 is qualified.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
