Description

Technical Field

[0001] This utility model relates to the field of automotive solenoid valve technology, and in particular to a solenoid valve coil frame and connector crimping tool. Background Technology

[0002] Automotive solenoid valves are actuators in automotive electronic control systems and are indispensable key components. Through electromagnetic force, solenoid valves achieve accurate control of liquids, gases, or gas-liquid mixtures. Automotive solenoid valves play a crucial role in fuel injection systems, hydraulic transmission systems, emission control systems, and air conditioning systems, contributing to high efficiency, environmental friendliness, and comfort in automobiles. The connector and coil frame are important components of solenoid valve products. During the production of solenoid valves, the connector and coil frame need to be positioned and installed using tooling. Before this, the coil frame must be positioned and installed within a shield. After positioning the connector and coil frame, the copper busbars on both sides of the connector must be bent at 90°. The assembly process for the connector and coil frame is complex, resulting in low production efficiency. Furthermore, manual inspection is required after positioning and crimping to ensure proper positioning, necessitating additional manpower for inspection. Additionally, existing tooling lacks protective features, posing a risk of injury during the crimping process. Summary of the Invention

[0003] This utility model provides a crimping fixture for a solenoid valve coil frame and connector. This crimping fixture can automatically perform crimping and positioning of the connector, coil frame, and shielding cover, as well as 90° bending of the pins on both sides of the connector, greatly improving production efficiency and saving labor costs. Moreover, the fixture is equipped with a displacement monitoring sensor to monitor the crimping and bending strokes, ensuring the stability of the product crimping and bending quality, improving the product's functional stability and service life.

Detailed Implementation

[0033] The present invention will now be described in detail with reference to the accompanying drawings.

[0034] The structure of the solenoid valve coil frame and connector crimping fixture provided in this embodiment is as follows: Figures 1-3As shown. The crimping fixture includes a base plate 1, an upper crimping assembly 2, a left crimping assembly 3, a right crimping assembly 4, an upper displacement monitoring sensor 801, and a left displacement monitoring sensor 802. Figure 1 (Not shown in the image), right displacement monitoring sensor 803 ( Figure 1 (Not shown in the drawing), outer casing 9 ( Figure 1 (Not shown in the diagram) Infrared sensing module 10 and controller 11. The crimping fixture can press the connector 7 into the coil frame 6, and at the same time press the coil frame into the shielding cover 5, and can achieve a 90° bend of the pins 701 on both sides of the connector.

[0035] In this embodiment, the structures of the shielding cover, coil frame, and connector are as follows: Figure 4 and Figure 6 As shown, the shielding cover is shaped like an inverted U-shape, including a bottom cover and side covers vertically connected to both sides of the bottom cover. Two coil frames are pressed into the shielding cover, and the coil of the solenoid valve is wound around the coil frames. Specifically, protrusions 601 are provided on the upper part of both sides of the two coil frames, and grooves 501 are provided at corresponding positions on the side covers of the shielding cover. When the two coil frames are vertically pressed into the shielding cover, the protrusions are pressed into the grooves. Specifically, slots 6011 are provided on the protrusions, and pins are provided on both sides of the connector. The pins include a first connecting piece 7011, a second connecting piece 7012, a vertical insert 7013, and a bent insert 7014. The first connecting piece is connected to the outside of the connector, the second connecting piece is connected to the first connecting piece and is parallel to the connector, the vertical insert is connected to the bottom of the second connecting piece, and the bent insert is connected to the end of the second connecting piece away from the first connecting piece and is perpendicular to the connector. When the connector is pressed onto the coil frame, the vertical prongs of the connector are inserted into the slots on the protrusions.

[0036] In this embodiment, the base plate is provided with a shielding cover limiting groove 101 and a connector limiting groove 102, and the base plate structure is as follows: Figure 5 As shown, the shielding cover, coil frame, and connector are placed sequentially from bottom to top on the shielding cover's positioning groove. Specifically, the structure of the shielding cover's positioning groove matches the bottom structure of the shielding cover, ensuring that the shielding cover can be snapped into the groove. Specifically, before crimping, the protrusions on the coil frame are manually positioned precisely into the grooves of the shielding cover, and the vertical inserts on the connector are precisely positioned into the slots on the coil frame, as shown. Figure 6 As shown, the shield, coil frame, and connector are then placed together on the shield's limiting groove. During the vertical pressing process, this ensures that the shield, coil frame, and connector do not shift. After pressing, the bottom protrusions of the connector are all within the connector's limiting groove, preventing contact between the bottom protrusions and the base plate. This avoids collisions between the bottom protrusions and the base plate, thus preventing damage to the connector's structure.

[0037] In this embodiment, the upper pressing assembly includes an upper pressing cylinder 201, an upper fixing plate 202, a support plate 203, and an upper positioning block 204. (See attached image) Figure 1 and Figure 3 The upper fixed plate is horizontally fixed to the base plate via a support plate. Specifically, the base plate is provided with a support plate limiting groove 103, and the support plate is vertically fixed to the support plate limiting groove. The upper fixed plate is horizontally fixed to the upper end of the support plate. The upper pressing cylinder is vertically mounted on the upper fixed plate. The piston rod 2011 of the upper pressing cylinder extends to the lower part of the upper fixed plate and is fixedly connected to the upper positioning pressure block, which is located above the connector. Specifically, the upper fixed plate is provided with a cylinder mounting hole, and the piston rod of the upper pressing cylinder extends from the cylinder mounting hole to the lower part of the upper fixed plate. The fixed seat of the upper pressing cylinder is fixedly connected to the upper fixed plate. The extension and retraction of the piston rod of the upper pressing cylinder drives the upper positioning pressure block to move up and down. To ensure the stability of the upper positioning block during its vertical movement, in this embodiment, upper guide rods 205 are vertically arranged and fixed between the upper fixed plate and the bottom plate. A guide plate 206 is fixedly connected to the piston rod of the upper pressing cylinder. The guide plate is sleeved on the upper guide rod. When the piston rod of the upper pressing cylinder extends or retracts, it drives the guide plate to move up and down along the upper guide rod, thereby limiting and guiding the movement and ensuring that the piston rod does not wobble during its vertical movement. Specifically, two upper guide rods are provided, and the guide plate has guide holes at corresponding positions on the upper guide rods. The upper guide rods pass through the guide holes on the guide plate and are fixed to the upper fixed plate and the bottom plate. Further, the guide plate is fixed to the bottom end of the piston rod of the upper pressing cylinder, and the upper positioning block is fixed to the bottom end of the guide plate. The upper positioning block moves up and down with the upper pressing cylinder, placing the shielding cover, coil frame, and connector onto the shielding cover's limiting groove. Then, driven by the upper pressing cylinder, the upper positioning block moves downwards, pressing the connector into the coil frame and simultaneously pressing the coil frame into the shielding cover. At this point, the protrusions on the coil frame are pressed into the grooves of the shielding cover, and the vertical inserts on the connector are pressed into the slots on the coil frame. Figure 7 As shown.

[0038] In this embodiment, connector pressing blocks 2041 and shielding cover pressing blocks 2042 are protruding from both sides of the bottom of the upper positioning block, such as... Figure 8 As shown, connector clamping blocks and shielding cover clamping blocks press down on both sides of the connector and the shielding cover, respectively, applying downward pressure to them. Specifically, four connector clamping blocks are provided, and their positions correspond to the positions of the pins on the connector. Furthermore, the connector clamping blocks are located above the first connecting piece of the pin. When pressed down, the connector clamping blocks are positioned precisely between the first and second connecting pieces, thus applying precise pressure above the protrusion and the protrusion, ensuring that the protrusion inserts into the slot of the protrusion, while the protrusion inserts into the groove below. Shielding cover clamping blocks press down on both sides of the shielding cover, ensuring that the shielding cover does not shift during the crimping process.

[0039] In this embodiment, the left and right crimping components automatically bend the bending tabs of the connector pins at a 90° angle. The connector after crimping and bending is as follows: Figure 9 As shown. The left and right crimping assemblies are symmetrically installed on the left and right sides of the base plate. The left and right crimping assemblies can move towards the center of the base plate respectively, pressing the bent tabs of the pins on both sides of the connector to a 90° bend. Specifically, the left crimping assembly includes a left crimping cylinder 301, a left fixing plate 302, and a left positioning block 303; the right crimping assembly includes a right crimping cylinder 401, a right fixing plate 402, and a right positioning block 403. See... Figure 1 The left and right fixed plates are vertically fixed to the left and right sides of the base plate, respectively. The left and right pressing cylinders are fixed to the left and right fixed plates, respectively, with the piston rods of both cylinders facing the center of the base plate. The left and right positioning blocks are fixed to the ends of the piston rods of the left and right pressing cylinders and move left and right with the piston rods. During bending operations, the left positioning block moves to the right with the left pressing cylinder, and the right positioning block moves to the left with the right pressing cylinder, bending the pins on both sides of the connector by 90°. Specifically, positioning block grooves 104 are provided on the left and right sides of the shielding cover limiting groove on the base plate. The left and right positioning blocks are located in the positioning block grooves and move along the grooves, providing support for the left and right positioning blocks.

[0040] In this embodiment, the shielding cover and the coil frame are provided with communicating positioning holes on their sides, see Figure 4 When the coil frame is pressed into the shielding cover, the positioning hole 602 on the coil frame coincides with the positioning hole 502 on the shielding cover, see... Figure 9 The left and right positioning blocks are respectively provided with left guide rod 304 and right guide rod 404. When the left and right positioning blocks are close to the two sides of the connector, the left guide rod and right guide rod extend into the positioning holes on the side of the shield and the coil frame, so that the concentricity of the shield and the coil frame is kept highly consistent.

[0041] In this embodiment, the controller is connected to the upper crimping assembly, the left crimping assembly, and the right crimping assembly, and the controller controls the movement of the upper crimping assembly, the left crimping assembly, and the right crimping assembly.

[0042] In this embodiment, the upper displacement monitoring sensor, the left displacement monitoring sensor, and the right displacement monitoring sensor are respectively installed at the upper crimping component, the left crimping component, and the right crimping component to monitor the moving displacement amounts of the upper crimping component, the left crimping component, and the right crimping component. The upper displacement monitoring sensor, the left displacement monitoring sensor, and the right displacement monitoring sensor are all connected to the controller. The controller feeds back whether the crimping is qualified according to the moving displacement amounts of the upper displacement monitoring sensor before and after crimping. The controller feeds back whether the bending process is qualified according to the displacement amounts of the left crimping component and the right crimping component.

[0043] The outer cover box body is installed on the bottom plate, and the outer cover box body covers the upper crimping component and the bottom plate, as Figure 2 shown. Specifically, the outer cover box body is made of transparent acrylic material. The infrared induction module is installed on the inner wall of the outer cover box body. The infrared induction module is connected to the controller to detect the situation when a person approaches the inside of the outer cover box body during crimping. When the upper crimping component is running and the controller receives the signal of a person approaching, the controller controls the upper crimping component to stop running. Specifically, when the left crimping component and the right crimping component are running and the controller receives the signal of a person approaching, the controller controls the left crimping component and the right crimping component to stop running.

[0044] Specifically, the controller includes a power supply module, a PCB board, a push-button switch, a travel indicator light, an infrared induction indicator light, and an alarm buzzer. The power supply module supplies power to the controller. The PCB board, the push-button switch, the travel indicator light, and the alarm buzzer, as Figure 10As shown, the power supply module supplies power to the controller. The PCB board, push-button switches, and upper pressing assembly are electrically connected. Pressing the push-button switch controls the movement of the upper pressing assembly. The PCB board is connected to the upper displacement monitoring sensor, travel indicator light, and alarm buzzer. The monitored pressing displacement controls the illumination of the travel indicator light and the alarm buzzer. The push-button switch controls the movement of the upper, left, and right pressing assemblies. The travel indicator light provides feedback on whether the pressing and bending travel is within acceptable limits. The infrared sensor indicator light provides feedback on the situation when a person approaches the inside of the outer casing during the operation of the upper, left, or right pressing assembly. The alarm buzzer sounds when the pressing or bending travel is unacceptable or when a person approaches. Furthermore, the push-button switch includes two push-button switches connected in series, and the travel indicator light includes an OK green light and an NG red light. When both buttons are pressed simultaneously, the upper crimping assembly begins to move downwards for the crimping process. If the crimping stroke is within acceptable limits, the "OK" green light illuminates; if the stroke is insufficient, the "NG" red light illuminates, and an alarm buzzer sounds to alert the operator. After the crimping process is complete, without pressing any buttons, the left and right crimping assemblies automatically move to the right and left respectively for the bending process. If the bending stroke is within acceptable limits, the "OK" green light illuminates; if the bending stroke is insufficient, the "NG" red light illuminates, and an alarm buzzer sounds to alert the operator. Throughout the crimping and bending processes, if a person approaches the inside of the outer casing, the infrared sensor indicator light illuminates, the controller immediately stops the fixture, and the alarm buzzer sounds to prevent accidental injury to personnel during automatic operation and to avoid potential safety hazards.

[0045] The solenoid valve coil frame and connector crimping fixture provided by this utility model can automatically crimp the connector, coil frame, and shielding cover, as well as bend the pins on both sides of the connector at 90°, greatly improving production efficiency and saving labor costs. Furthermore, the fixture is equipped with a displacement monitoring sensor to monitor the crimping and bending strokes, ensuring the stability of the crimping and bending quality, and improving the product's functional stability and service life. Simultaneously, an infrared sensing module enables manual stopping of the fixture, improving its safety performance.
