Description

Technical Field

[0001] The invention relates to the field of return spring assemblies, in particular to fully automatic assembly and loading equipment for return spring assemblies of automatic transmissions. Background Art

[0002] The return spring assembly of an automatic transmission is a key component of its internal actuator, responsible for driving the relevant components to precisely return to their original position after actuation. This assembly typically consists of a riveted plate, a plug-in plate, and several return springs sandwiched between them and evenly distributed along a circular path. To ensure uniform circumferential force during operation and to avoid uneven wear, sticking, or abnormal noise, the spiral direction of all return springs in the same assembly must be strictly consistent. Mixed spiral directions can cause the torque generated by spring compression and release to interfere with each other, disrupting force balance, seriously affecting return performance and reliability, and even causing transmission failure.

[0003] On automated assembly lines, achieving efficient and accurate loading and sorting of return springs is a core challenge. Springs are inherently flexible, easy to wind, and have varying postures and directions of rotation. Traditional vibrating plate loading technology is difficult to meet usage requirements, primarily due to the following issues: 1. Existing screening structures struggle to effectively handle all the complex postures presented during spring delivery, especially radially distributed springs, which are prone to getting stuck or causing confusion. 2. Existing technology is completely unable to distinguish the internal spiral direction, resulting in mixed rotational directions in the output springs, which cannot meet the core consistency requirements for component assembly. 3. Springs with unqualified postures that are screened out are usually simply discarded and fall directly back to the bottom of the vibrating plate, requiring them to re-participate in the entire, lengthy loading cycle, increasing the burden and uncertainty of the cycle. Summary of the Invention

[0004] In order to solve the aforementioned technical problems, the present invention provides a fully automatic assembly and loading equipment for automatic transmission return spring assemblies.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present invention by illustrating examples of the present invention.

[0022] The directional terms used in the following description refer to the directions shown in the drawings and do not limit the specific structure of the present invention. It should also be noted that, in the description of the present invention, unless otherwise specified or limited, the terms "installation" and "connection" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0023] The embodiment of the present invention provides a fully automatic assembly and loading device for an automatic transmission return spring assembly, see Figure 1 、 Figure 5 、 Figure 7The feeding equipment includes a driving mechanism 200 installed on the upper surface of the vibration-damping base plate 101 and a vibration plate 102 installed above the driving mechanism 200. The vibration-damping base plate 101 facilitates the installation of the driving mechanism 200 and has a certain shock-absorbing effect. An annular guide plate 105 with a threaded track is fixed to the inner wall of the vibration plate 102 for guiding the springs contained in the vibration plate 102. The driving mechanism 200 provides power for the vibration plate 102 and is used to transport the springs in the vibration plate 102 outward along the annular guide plate 105, and complete the orderly arrangement of the springs during the transportation process, and finally transport the orderly arranged springs to a number of output guide rails 103 for completing the installation of the subsequent workstation reset spring assembly. The bottom of the output guide rail 103 is installed on the vibration-damping base plate 101 through a number of support blocks 104. The support blocks 104 are used to flexibly adjust the heights of the several output guide rails 103 to adapt to the transportation requirements of the springs.

[0024] The first correction part 300, the screening part 400 and the second correction part 500 are installed on the vibration disk 102 in order from high to low. The first correction part 300 is used to initially straighten the springs contained in the vibration disk 102 so that the springs continue to flow to the screening part 400 in a predetermined posture, and the screening part 400 is used to preliminarily screen the springs that are not distributed in a predetermined posture, so that they flow back to the vibration disk 102 for reuse.

[0025] The remaining springs whose movement posture meets the use requirements continue to flow to the second correction part 500. The second correction part 500 classifies the springs according to the spiral direction of the springs, so that springs with different spiral directions are output outward through different output guide rails 103 to meet the installation and use requirements of the reset spring assembly.

[0026] like Figure 2 As shown, the return spring assembly of the automatic transmission consists of a rivet plate and a plug-in plate, as well as several return springs sandwiched between the two and evenly distributed along a ring. In order to ensure the force balance of the rivet plate and the plug-in plate at various positions along the ring, the springs in the same return spring assembly must maintain the same spiral direction.

[0027] Through the above-mentioned structure, the present invention processes the springs in a messy state placed inside the vibration disk 102 through the first correction part 300, the screening part 400 and the second correction part 500 in sequence, so that the springs are output outward along the output guide rail 103 in a uniform posture, and ensures that the spiral direction of the springs output by each output guide rail 103 remains consistent, so as to meet the installation requirements of the reset spring assembly.

[0028] As a further explanation of the above embodiments, see Figure 3 、 Figure 4The driving mechanism 200 includes a fixed disk 201, which is coaxially fixedly mounted on the bottom of the vibration disk 102. A magnet 202 is fixedly mounted on the bottom of the fixed disk 201. An electromagnet 203 is arranged directly below the magnet 202. A gap is provided between the magnet 202 and the electromagnet 203. The bottom of the electromagnet 203 is fixedly mounted on a mounting base 204. The mounting base 204 is fixedly mounted on the vibration damping base plate 101. The mounting base 204 is fixed to the fixed disk 201 through a number of inclined spring plates 205.

[0029] The pulse power supply of the electromagnet 203 is electrically connected, so that the electromagnet 203 generates a periodic magnetic field after being energized, thereby intermittently generating an attractive force on the electromagnet 203 .

[0030] The plurality of spring plates 205 are evenly distributed along the circumference of the mounting base 204 . The plurality of spring plates 205 are all tilted and tilted along the same rotation direction.

[0031] A housing 206 is fixedly installed in an annular shape on the outer side of the structure to protect the structure and maintain the normal working state of the driving mechanism 200.

[0032] The above structure of this embodiment enables the electromagnet 203 to generate periodic attraction with the magnet 202 after being energized. When the electromagnet 203 attracts the magnet 202, the gap between the magnet 202 and the electromagnet 203 becomes smaller, driving the horizontal height of the vibration disk 102 and the fixed disk 201 to decrease, and under the action of several inclined spring plates 205, the fixed disk 201 and the vibration disk 102 rotate at a certain angle relative to the mounting base 204. When the electromagnet 203 no longer attracts the magnet 202, the fixed disk 201 and the vibration disk 102 return to their original positions under the elastic force of the spring plates 205.

[0033] The spring material contained in the vibration disk 102 has its own inertia. Under the premise of the periodic motion of the vibration disk 102 bouncing up and down and rotating at a certain angle, the spring in the vibration disk 102 will spiral up along the annular guide plate 105 with a threaded track, thereby completing the outward transportation of the spring material.

[0034] Among them, the annular guide plate 105 is tilted along the radial cross-section of the vibration disk 102, and the tilt direction is from top to bottom, from the axis close to the vibration disk 102 to the direction away from the axis of the vibration disk 102. This setting method makes it easier for the annular guide plate 105 to receive materials, avoiding frequent falling of materials due to vibration, which affects the material transmission efficiency.

[0035] As a further explanation of the above embodiments, see Figure 5 、 Figure 7The first correction part 300 includes a correction block 302, a first end of the correction block 302 is fixed and tangent to the inner edge of the top of the annular guide plate 105, a second end of the correction block 302 is fixed and tangent to the top of the vibration disk 102, and the height of the correction block 302 gradually increases from the first end to the second end.

[0036] The first correction part 300 also includes a transition plate 303, the first end of the transition plate 303 is fixed to the top of the vibration disk 102 and is arranged tangently, the second end of the correction block 302 is fixed to the highest end of the first material channel 304, and a gap channel is formed between the correction block 302 and the transition plate 303, and the width of the gap channel is 1.1 times the outer diameter of the spring.

[0037] The first material channel 304 is arranged along a spiral track from high to low on the outer surface of the vibration disk 102. The first material channel 304 includes a bottom plate and a side plate. The bottom plate of the first material channel 304 is inclined along the radial cross-section of the vibration disk 102, and the inclination direction is from top to bottom from close to the axis of the vibration disk 102 to away from the axis of the vibration disk 102; the side plates of the first material channel 304 are perpendicular to the bottom plate of the first material channel 304.

[0038] The second end of the first material channel 304 is aligned with one of the output guide rails 103 through the transition material channel 305. A guide rod 306 is fixed to the inner edge of the transition material channel 305. The guide rod 306 is used to guide the spring during the movement.

[0039] The spring material in the vibration plate 102 is guided by the annular guide plate 105 and moves to the top of the annular guide plate 105. Its movement posture can be basically divided into three categories, such as Figure 5 As shown, for the convenience of observation and description, the spring is replaced by a cylindrical tubular structure in the accompanying drawings. The spring of the first type of motion posture is as follows Figure 5 The length direction of a is distributed along the tangent direction of the intersection line of the vibration disk 102 and the annular guide plate 105; the spring of the second type of motion posture is as follows Figure 5 b in the figure has its length direction coincident with the radial direction of the vibration disk 102, and its end is in contact with the inner wall of the vibration disk 102; the spring of the third type of motion posture is as follows Figure 5 In the figure, c has a length direction that is substantially consistent with the axial direction of the vibration disk 102, and an outer circumferential surface that is in contact with the inner wall of the vibration disk 102; for the convenience of subsequent representation, the springs in the above three postures are defined as type a spring, type b spring, and type c spring, respectively.

[0040] When the spring in the vibration disk 102 moves to the highest point along the annular guide plate 105, that is, when the spring begins to contact the correction block 302, the type A spring and the type C spring will basically not be hindered by the correction block 302, so that they can maintain their original movement posture through the gap channel formed by the correction block 302 and the transition plate 303, enter the first material channel 304 and continue to maintain their original movement posture and flow downward. The type B spring will tilt under the action of the correction block 302. If the end away from the axis of the vibration disk 102 tilts upward, the type B spring will fall back to the bottom of the vibration disk 102 under the action of the correction block 302. Conversely, if the end close to the axis of the vibration disk 102 tilts upward, the type B spring will gradually increase its tilt angle under the action of the correction block 302 until it turns into a type C spring. However, if the type B spring falls after entering the gap channel between the correction block 302 and the transition plate 303, the type B spring will turn into a type A spring.

[0041] Therefore, through the above structure, the posture of the type B spring is corrected or eliminated, so that the spring passing through the gap channel between the correction block 302 and the transition plate 303 can only maintain the posture of the type A spring and the type C spring, realizing the preliminary integration of the springs.

[0042] As a further explanation of the above embodiments, see Figure 5 、 Figure 6 、 Figure 10 The screening part 400 includes a leakage hole 401, which is opened on the side plate of the first material channel 304, and the length direction of the leakage hole 401 is arranged along the circumference of the first material channel 304. This method allows the Class A spring to pass through the leakage hole 401 and fall downward under the action of gravity when passing through the position of the leakage hole 401.

[0043] A second material channel 402 is arranged directly below the first material channel 304. The structure of the second material channel 402 is the same as that of the first material channel 304. A baffle 403 is fixed on the side panel of the second material channel 402. The baffle 403 is aligned with the leakage hole 401 up and down. The bottom end of the second material channel 402 is connected to the interior of the vibration disk 102 through a return hole 404 opened on the side wall of the vibration disk 102.

[0044] Through the above-mentioned structure, this embodiment allows the Class A spring to fall downward through the leakage hole 401, and under the obstruction of the baffle 403, it falls smoothly into the second material channel 402, and the vibration of the vibration plate 102 drives the spring in the second material channel 402 to flow downward along the second material channel 402 to the bottom of the second material channel 402, and then return to the inside of the vibration plate 102 through the return hole 404 for the next recycling.

[0045] After screening by the screening unit 400 , the Class A springs in the first material channel 304 are removed, and the remaining Class C springs continue to flow backward along the first material channel 304 , while the removed Class A springs are transported back to the inside of the vibration plate 102 through the second material channel 402 for continued recycling.

[0046] As a further explanation of the above embodiments, see Figure 7 、 Figure 9 The second correction part 500 includes a mounting platform 501 fixedly mounted on the outer side of the bottom end of the second material channel 402. A camera 502 and an air jet 503 are fixedly mounted on the mounting platform 501. The camera 502 is located upstream of the first material channel 304 relative to the air jet 503. The camera 502 is used to observe the spring moving in the first material channel 304 and determine the spiral direction of the spring. The nozzle of the air jet 503 is aligned with the top of the spring and is used to selectively spray gas to the top of the spring to drive the spring to tip over.

[0047] The first material channel 304 is provided with a flipping opening 504 on the bottom plate located at the downstream position of the mounting platform 501. When the tilted spring passes through the flipping opening 504, it can flip under the action of gravity and pass through the flipping opening 504, and fall onto the third material channel 505 installed directly below the flipping opening 504, and continue to be transported downward along the third material channel 505. The structure of the third material channel 505 is the same as that of the first material channel 304, and the bottom end of the third material channel 505 is aligned with another output guide rail 103.

[0048] In this embodiment, after screening by the screening unit 400, only Class C springs remain on the first material channel 304, but the spiral direction of the Class C springs is different. In order to further distinguish them, the camera 502 is used to collect signals and determine the spiral direction of the springs. Taking the right spiral spring as an example, when the camera 502 observes the right spiral spring, the jet tube 503 is immediately started, so that under the action of external force, the top end of the right spiral spring tilts inward, thereby converting it into a Class B spring.

[0049] The minimum distance between the flip opening 504 and the first material channel 304 is 1.2 times the outer diameter of the spring. This structure can ensure that the type C spring can stick to the inner side of the side plate of the first material channel 304 and then pass through the flip opening 504 smoothly, while the type B spring will fall downward through the flip opening 504, thereby realizing the distinction between springs with different spiral directions.

[0050] Due to the structural characteristics of the flip port 504, the type C spring on the first material channel 304 can smoothly pass through the flip port 504 and continue to flow downward, and when the type B spring moves to the position of the flip port 504, its inner end begins to tilt downward and flip, so that the entire spring flips 90 degrees after passing through the flip port 504, and falls back onto the third material channel 505 in the posture of a type C spring, and continues to flow downward along the third material channel 505 to another output guide rail 103, which is convenient for the subsequent assembly and use of the reset spring assembly.

[0051] While the embodiments of the present invention are described above, these embodiments do not exhaustively describe all details, nor do they limit the present invention to only specific embodiments. Clearly, many modifications and variations can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to make good use of the present invention and its modifications and uses. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
