Description

Technical Field

[0001] This invention relates to the field of return spring assemblies, and more particularly to a fully automated assembly and feeding device for return spring assemblies of automatic transmissions. Background Technology

[0002] The return spring assembly of an automatic transmission is a key component of its internal actuators, responsible for driving related parts to accurately return to their original position after action. The return spring assembly typically consists of riveted plates, insert plates, and several return springs evenly distributed in a ring between them. To ensure uniform circumferential force during operation and avoid uneven wear, jamming, or abnormal noise, the helix direction of all return springs in the same assembly must be strictly consistent. Mixed helix directions will cause the torque generated by spring compression and release to interfere with each other, disrupting the force balance, severely affecting return performance and reliability, and even causing transmission failure.

[0003] On automated assembly lines, achieving efficient and accurate feeding and sorting of return springs is a core challenge. Springs themselves are characterized by flexibility, easy winding, and varying postures and directions of rotation. Traditional vibratory feeder feeding technology is insufficient to meet the requirements, mainly in the following aspects: 1. Existing screening structures cannot effectively handle all the complex postures presented during spring transport, especially radially distributed springs, which are prone to jamming or causing confusion; 2. Existing technology cannot distinguish the internal helical direction, resulting in mixed rotation directions of output springs, failing to meet the core consistency requirements of component assembly; 3. Unqualified posture springs are usually simply rejected and allowed to fall directly back to the bottom of the vibratory feeder, requiring them to re-participate in the entire lengthy feeding cycle, increasing the cycle burden and uncertainty. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a fully automated assembly and feeding device for automatic transmission reset spring assemblies. By setting up a multi-stage sorting and adjustment structure, it solves the problem of efficient and high-precision posture sorting and spiral direction sorting of scattered springs.

[0016] Preferably, the first corrective part further includes:

The first material channel includes a bottom plate and a side plate. The bottom plate is arranged outward and downward along the radial section of the vibratory feeder, and the side plate is perpendicular to the bottom plate.

[0018] The transition channel is used to connect the first channel and the output guide rail, and a guide rod is provided on its inner side.

[0019] Preferably, the material leakage hole is arranged along the circumference of the first material channel in the length direction, and the side wall of the second material channel is provided with a baffle that is vertically aligned with the material leakage hole.

[0020] Preferably, the second corrective part further includes:

[0021] The mounting platform is fixed to the outside of the second material channel and is used to mount the camera and the jet pipe;

[0022] The camera is located upstream of the jet pipe, and the jet pipe nozzle is aligned with the top of the spring.

[0023] Preferably, a third material channel is provided directly below the flip-out port, and the end of the third material channel is connected to another output guide rail.

[0024] Preferably, the output guide rail is mounted on the vibration damping base plate via a support block, and the height of the support block is adjustable to suit installation requirements.

[0025] Preferably, the gap channel of the first correction part is configured as follows:

[0026] Springs with tangential and axial distributions are allowed to pass through, while radially distributed springs are corrected to be tangentially or axially distributed, or rejected.

[0027] Preferably, the second corrective part is configured as follows:

[0028] The jet pipe sprays springs with different directions of rotation and axial distribution into radially distributed springs, and the flipping port flips the radially distributed springs 90° before they fall into the third material channel.

[0050] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the invention.

[0051] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the invention. It should also be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0052] Embodiments of the present invention provide a fully automated assembly and feeding device for automatic transmission return spring assemblies, see [link to documentation]. Figure 1 , Figure 5 , Figure 7 The feeding equipment includes a drive mechanism 200 mounted on the upper surface of a vibration damping base plate 101 and a vibratory feeder 102 mounted above the drive mechanism 200. The vibration damping base plate 101 facilitates the installation of the drive mechanism 200 and provides a certain vibration damping effect. The inner wall of the vibratory feeder 102 is fixed with an annular guide plate 105 with a threaded track, which is used to guide the springs placed inside the vibratory feeder 102. The drive mechanism 200 provides power to the vibratory feeder 102 to transport the springs inside the vibratory feeder 102 outward along the annular guide plate 105, and completes the orderly arrangement of the springs during the transportation process. Finally, the orderly arranged springs are transported to several output guide rails 103 for the installation of subsequent station reset spring assemblies. The bottom of the output guide rails 103 is mounted on the vibration damping base plate 101 by several support blocks 104. The support blocks 104 are used to flexibly adjust the height of the output guide rails 103 to adapt to the spring transportation requirements.

[0053] The vibratory plate 102 is equipped with a first correction section 300, a screening section 400, and a second correction section 500 in descending order. The first correction section 300 is used to initially straighten the springs inside the vibratory plate 102, so that the springs continue to flow to the screening section 400 in a predetermined posture. The screening section 400 is used to initially screen the springs that are not distributed in a predetermined posture, so that they flow back into the vibratory plate 102 for reuse.

[0054] The remaining springs whose motion posture meets the usage requirements continue to flow to the second correction section 500. The second correction section 500 classifies the springs according to their helix direction, so that springs with different helix directions are output outward through different output guides 103 to meet the installation and usage requirements of the reset spring assembly.

[0055] like Figure 2 As shown, the return spring assembly of an automatic transmission consists of riveted plates and insert plates, as well as several return springs evenly distributed in a ring between the two. In order to ensure the force balance of the riveted plates and insert plates at various positions in the ring direction, the springs in the same return spring assembly must keep the helical direction consistent.

[0056] Through the above structure, the springs that are in a disordered state inside the vibratory plate 102 are processed by 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 the spiral direction of the springs output from each output guide rail 103 is kept consistent, so as to meet the installation requirements of the reset spring assembly.

[0057] For a further explanation of the above embodiments, see Figure 3 , Figure 4 The drive mechanism 200 includes a fixed plate 201, which is coaxially fixedly installed on the bottom of the vibratory plate 102. A magnet 202 is fixedly installed on the bottom of the fixed plate 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 installed on the mounting base 204. The mounting base 204 is fixedly installed on the vibration damping base plate 101. The mounting base 204 is fixed to the fixed plate 201 by a number of inclined spring plates 205.

[0058] The electromagnet 203 is electrically connected to a pulse power supply, which causes the electromagnet 203 to generate a periodic magnetic field after being energized, thereby intermittently attracting the electromagnet 203.

[0059] Among them, a number of spring plates 205 are evenly distributed along the circumference of the mounting base 204, and the spring plates 205 are all inclined and inclined in the same direction of rotation.

[0060] The outer side of the above structure is fixedly fitted with a housing 206 in an annular shape to protect the structure and maintain the normal operation of the drive mechanism 200.

[0061] The above-described structure of this embodiment enables the electromagnet 203 to generate a periodically spaced attractive force 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, causing the horizontal height of the vibrating plate 102 and the fixed plate 201 to decrease. Under the action of several inclined spring plates 205, the fixed plate 201 and the vibrating plate 102 rotate at a certain angle relative to the mounting base 204. When the electromagnet 203 no longer attracts the magnet 202, the fixed plate 201 and the vibrating plate 102 return to their original positions under the elastic force of the spring plates 205.

[0062] Based on its own inertia, the spring material contained in the vibratory plate 102 will spiral upward along the annular guide plate 105 with a spiral trajectory under the condition of the vibratory plate 102 oscillating up and down and rotating at a certain angle, thereby completing the outward conveying of the spring material.

[0063] The annular guide plate 105 is inclined along the radial section of the vibratory plate 102, with the inclination direction from top to bottom and from the axis closer to the axis of the vibratory plate 102 to the direction away from the axis of the vibratory plate 102. This arrangement makes it easier for the material to be received above the annular guide plate 105, avoiding the material from falling off frequently due to vibration and affecting the material transfer efficiency.

[0064] For a further explanation of the above embodiments, see Figure 5 , Figure 7 The first correction part 300 includes a correction block 302. The first end of the correction block 302 is fixed and tangentially disposed to the inner edge of the top of the annular guide plate 105. The second end of the correction block 302 is fixed and tangentially disposed to the top of the vibrating plate 102. The height of the correction block 302 gradually increases from the first end to the second end.

[0065] The first correction section 300 also includes a transition plate 303. The first end of the transition plate 303 is fixed and tangentially disposed to the top of the vibrating plate 102. The second end of the correction block 302 is fixed to the highest end of the first material channel 304. A gap channel is formed between the correction block 302 and the transition plate 303. The width of the gap channel is 1.1 times the outer diameter of the spring.

[0066] The first material channel 304 is arranged along a spiral trajectory from high to low on the outer surface of the vibratory plate 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 section of the vibratory plate 102, and the inclination direction is from top to bottom from the direction close to the axis of the vibratory plate 102 to the direction away from the axis of the vibratory plate 102. The side plate of the first material channel 304 is arranged perpendicular to the bottom plate of the first material channel 304.

[0067] The second end of the first feed channel 304 is aligned with one of the output guide rails 103 via the transition feed channel 305. A guide rod 306 is fixed to the inner edge of the transition feed channel 305. The guide rod 306 is used to guide the spring during the movement process.

[0068] The spring material inside the vibratory feeder 102, guided by the annular guide plate 105, moves to the top of the annular guide plate 105. Its motion can be broadly categorized into three types, such as... Figure 5 As shown, for ease of observation and description, a cylindrical tubular structure is used to represent the spring in the attached diagram. The spring for the first type of motion posture is as follows: Figure 5 In the figure, 'a' has its length direction distributed along the tangent direction of the intersection line of the vibrating disk 102 and the annular guide plate 105; the spring of the second type of motion posture is as follows: Figure 5 In the figure, b, its length direction coincides with the radial direction of the vibrating plate 102, and its end is in contact with the inner wall of the vibrating plate 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 basically consistent with the axis of the vibrating plate 102, and its outer circumferential surface is in contact with the inner wall of the vibrating plate 102. For ease of subsequent representation, the springs in the above three postures are defined as type a spring, type b spring, and type c spring, respectively.

[0069] When the spring inside the vibratory feeder 102 moves along the annular guide plate 105 to its highest point, that is, when the spring begins to contact the straightening block 302, the type A and type C springs are basically not hindered by the straightening block 302, thus maintaining their original motion posture through the gap channel formed by the straightening block 302 and the transition plate 303, entering the first material channel 304 and continuing to maintain their original motion posture as they flow downwards. The type B spring will tilt under the action of the straightening block 302. If the end away from the axis of the vibratory feeder 102 tilts upwards, the type B spring will fall back to the bottom of the vibratory feeder 102 under the action of the straightening block 302. Conversely, if the end close to the axis of the vibratory feeder 102 tilts upwards, the tilt angle of the type B spring will gradually increase under the action of the straightening block 302 until it transforms into a type C spring. However, if the type B spring tilts after entering the gap channel between the straightening block 302 and the transition plate 303, it will transform into a type A spring.

[0070] Therefore, through the above structure, the attitude of type b springs is corrected or eliminated, so that the springs passing through the gap channel between the correction block 302 and the transition plate 303 can only maintain the attitude of type a springs and type c springs, thus achieving the initial integration of springs.

[0071] For a further explanation of the above embodiments, see Figure 5 , Figure 6 , Figure 10The screening unit 400 includes a material leakage hole 401, which is opened on the side plate of the first material channel 304. The length direction of the material leakage hole 401 is arranged along the circumference of the first material channel 304. This arrangement allows the type A spring to pass through the material leakage hole 401 and fall downward under the action of gravity when it passes the position of the material leakage hole 401.

[0072] A second material channel 402 is provided 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 plate of the second material channel 402. The baffle 403 is aligned vertically with the material leakage hole 401. The bottom end of the second material channel 402 is connected to the inside of the vibrating plate 102 through the return hole 404 opened on the side wall of the vibrating plate 102.

[0073] In this embodiment, the above structure allows the type A spring to fall downward through the discharge hole 401. Under the obstruction of the baffle 403, it falls smoothly into the second material channel 402. The vibration of the vibrating 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. Then, it returns to the vibrating plate 102 through the return hole 404 for the next cycle.

[0074] After being screened by the screening section 400, type A springs in the first material channel 304 are rejected, while the remaining type C springs continue to flow backward along the first material channel 304. The rejected type A springs are then transported back to the vibratory feeder 102 through the second material channel 402 for continued recycling.

[0075] For a further explanation of the above embodiments, see Figure 7 , Figure 9 The second correction unit 500 includes a mounting platform 501 fixedly installed on the outer side of the bottom end of the second material channel 402. A camera 502 and a jet pipe 503 are fixedly installed on the mounting platform 501. The camera 502 is located upstream of the first material channel 304 relative to the jet pipe 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 jet pipe 503 is aligned with the top of the spring and is used to selectively spray gas onto the top of the spring to drive the spring to tilt.

[0076] The first material channel 304 has a flip-out opening 504 on its base plate located downstream of the mounting platform 501. When the tilting spring passes through the flip-out opening 504, it can flip under the action of gravity and pass through the flip-out opening 504, falling onto the third material channel 505 installed directly below the flip-out opening 504, and continuing to be conveyed 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.

[0077] In this embodiment, after screening by the screening unit 400, only type C springs remain on the first material channel 304. However, the spiral direction of type C springs is different. In order to further distinguish them, the camera 502 collects signals and determines the spiral direction of the springs. Taking a right-hand spiral spring as an example, when the camera 502 observes a right-hand spiral spring, it immediately activates the jet pipe 503, causing the top of the right-hand spiral spring to tilt inward under the action of external force, thereby transforming it into a type B spring.

[0078] The minimum distance between the flip-out port 504 and the first material channel 304 is 1.2 times the outer diameter of the spring. This structure ensures that the C-type spring can adhere to the inner side of the side plate of the first material channel 304 and pass smoothly through the flip-out port 504, while the B-type spring will fall downward through the flip-out port 504, thus realizing the distinction between springs with different helical directions.

[0079] Due to the structural characteristics of the flip-out port 504, the type C spring on the first feed channel 304 can smoothly pass through the position of the flip-out port 504 and continue to flow downwards. When the type B spring moves to the position of the flip-out port 504, its inner end begins to tilt downwards and flip, so that the entire spring flips 90 degrees after passing through the flip-out port 504 and falls back to the position of the type C spring onto the third feed channel 505. It then continues to flow downwards along the third feed channel 505 into another output guide rail 103, which facilitates the subsequent assembly and use of the reset spring assembly.

[0080] The embodiments described above are not exhaustive, nor do they limit the invention to any specific embodiments. Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to effectively utilize the invention and its modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the invention should be included within the scope of protection of the invention.
