Description

Technical Field

[0001] This invention relates to the field of steering wheel wrapping processing apparatus, and more particularly to processing equipment and processing methods for steering wheel wrapping. Background Technology

[0002] Currently, the covering of the flexible outer surface of the car steering wheel, such as the steering wheel ring or heating pad, is often done manually. Workers usually first pre-attach the flexible surface to the outside of the steering wheel frame with glue, and then manually apply pressure and heat to the steering wheel frame with glue, so that the flexible surface stretches, fits and is pressed tightly to cover the outside of the steering wheel frame. After the glue cures, the steering wheel with the ring or heating pad is produced.

[0003] During manual pressure application, it is difficult to ensure that the adhesive is evenly distributed and errors are prone to occur. As the flexible skin gradually adheres to the steering wheel frame, bulges and wrinkles are likely to appear, resulting in poor coverage of the flexible skin and low efficiency of manual application.

[0004] More importantly, after manual processing, existing technologies typically involve allowing the pre-finished product to stand for a predetermined time, allowing the adhesive on the pre-finished product to air dry naturally or be artificially heated. However, due to the predetermined fluidity of the adhesive, prolonged standing time or uneven and inefficient artificial heating may cause partial adhesive leakage in certain areas of the steering wheel frame, thereby exacerbating the occurrence of bulges and wrinkles. Summary of the Invention

[0005] One advantage of this invention is that it provides processing equipment and processing methods for steering wheel wrapping, which have a good wrapping effect on the steering wheel frame, are not prone to bulges and wrinkles, and have high wrapping efficiency.

[0006] Another advantage of this invention is that it provides processing equipment and methods for steering wheel wrapping, which heats the steering wheel frame and flexible skin evenly and efficiently, which helps to accelerate the uniform curing of the adhesive and improve the wrapping efficiency and effect.

[0007] To achieve at least one of the advantages of the present invention, the present invention provides a processing apparatus for steering wheel wrapping, comprising: an apparatus body; a support plate; the support plate being liftably disposed on the apparatus body for supporting a steering wheel frame pre-adheded with a flexible skin; a plurality of clamping members disposed on the support plate and arranged around the outer periphery of the steering wheel frame, each clamping member having a clamping mold, the plurality of clamping molds being movable radially along the steering wheel frame to clamp the steering wheel frame and press the flexible skin radially; an upper clamping assembly disposed on the apparatus body and located above the clamping members; a lower clamping assembly disposed on the support plate and located below the clamping members, the lower clamping assembly being used to press the flexible skin upward, and the lower clamping assembly and the clamping members being adapted to move closer to the upper clamping assembly as the support plate rises, so that the upper clamping assembly presses the flexible skin downward; and a lifting drive member connected to the support plate for driving the support plate to rise and fall.

[0008] According to one embodiment of the present invention, each of the clamping members further includes a clamping base disposed on the bearing plate; a clamping slide rail disposed on the clamping base and extending radially, the clamping mold being slidably disposed on the clamping slide rail for radial movement; and a clamping cylinder connected to the clamping mold for driving the clamping mold to slide.

[0009] According to one embodiment of the present invention, a heating cavity suitable for accommodating hot fluid is formed within the clamping mold.

[0010] According to one embodiment of the present invention, the upper clamping assembly includes a locking member disposed on the device body; and an upper clamping member located above the locking member. The upper clamping member is rotatably disposed on the device body to switch between a clamping position and an open position. When in the clamping position, the upper clamping member covers the area between the plurality of clamping members and cooperates with the locking member to be locked. When in the open position, the upper clamping member no longer covers the area between the plurality of clamping members and is no longer locked.

[0011] According to one embodiment of the present invention, the upper clamping member is provided with a locking rod, the locking rod having an annular locking groove formed on its circumferential surface. The locking member includes: a locking base disposed on the device body; a locking slide rail disposed on the locking base; a locking member slidably disposed on the locking slide rail, the locking member having a locking port with a side opening, the locking member being adapted to be installed in the locking groove through the locking port when sliding, so as to lock the locking rod; and a locking cylinder connected to the locking member for driving the locking member to slide.

[0012] According to one embodiment of the present invention, when the plurality of clamping molds are close to each other, they form clamping holes suitable for fitting onto the outer periphery of the steering wheel frame. The upper clamping member includes a flip cover, which is flip-open and disposed on the device body; and an upper clamping mold, which forms a downwardly opening upper clamping groove, which is adapted to align with the clamping hole as the flip cover flips.

[0013] According to one embodiment of the present invention, the lower pressing assembly includes a lower pressing mold disposed below the pressing mold; and a pressing cylinder connected to the lower pressing mold for driving the lower pressing mold to press the flexible skin upward.

[0014] According to one embodiment of the present invention, a positioning seat is further included, the positioning seat being disposed on the support plate, and the positioning seat having a positioning post adapted to be inserted into the inner hole of the steering wheel frame.

[0015] According to one embodiment of the present invention, the positioning seat is provided with a sensing sensor for sensing whether the steering wheel frame is installed on the positioning seat.

[0016] The present invention also provides a processing method for processing a steering wheel frame pre-attached with the flexible skin using the processing equipment described above. The processing method includes the following steps: placing the steering wheel frame pre-attached with the flexible skin on the support plate; moving a plurality of clamping molds radially toward each other along the radial direction of the steering wheel frame to press the flexible skin radially, so that the flexible skin is pressed tightly to cover the outer peripheral surface of the steering wheel frame; pressing the flexible skin upward by the lower clamping assembly, so that the flexible skin is pressed tightly to cover the upper surface of the steering wheel frame; and driving the support plate upward by the lifting drive member to move the clamping molds and the lower clamping assembly upward toward the upper clamping assembly, thereby causing the upper clamping assembly to press the flexible skin downward, thereby pressing the flexible skin tightly to cover the lower surface of the steering wheel frame.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Figure 1 This is a schematic diagram of the structure of a processing device 100 for steering wheel wrapping according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of some components according to an embodiment of the present invention. (See attached diagram.) Figures 1 to 2 The processing equipment 100 for steering wheel wrapping according to the present invention includes a main body 10, a support plate 20, multiple clamping components 30, an upper clamping assembly 40, a lower clamping assembly 50, and a lifting drive component 60.

[0036] The support plate 20 is vertically and flexibly mounted on the main body 10 of the equipment and is used to support the steering wheel frame pre-attached with a flexible skin. That is, before the processing equipment 100 for steering wheel wrapping presses the flexible skin onto the steering wheel frame, the steering wheel frame pre-attached with the flexible skin can be placed on the support plate 20. For example, when the steering wheel frame is an aluminum alloy frame and the flexible skin is a heating pad or rubber ring for the steering wheel, the aluminum alloy frame pre-attached with the heating pad or rubber ring can be placed on the support plate 20 first.

[0037] Multiple clamping members 30 are disposed on the support plate 20 and arranged around the outer periphery of the steering wheel frame. Each clamping member 30 has a clamping mold 31, and the multiple clamping molds 31 can move radially along the steering wheel frame to clamp the steering wheel frame and press the flexible skin radially. That is, after the steering wheel frame with the pre-adheded flexible skin is placed on the support plate 20, the multiple clamping members 30 can move radially along the steering wheel frame to approach each other, thereby pressing the flexible skin radially to cover the steering wheel frame, so that the flexible skin can be pressed tightly to cover the outer peripheral surface of the steering wheel frame and the steering wheel frame is clamped.

[0038] The upper clamping assembly 40 is disposed on the device body 10 and located above the clamping member 30. The lower clamping assembly 50 is disposed on the support plate 20 and located below the clamping mold 31. The lower clamping assembly 50 is used to press the flexible skin upward, and the lower clamping assembly 50 and the clamping member 30 are adapted to move closer to the upper clamping assembly 40 as the support plate 20 rises, so that the upper clamping assembly 40 presses the flexible skin downward. The lifting drive 60 is connected to the support plate 20 and is used to drive the support plate 20 to rise and fall.

[0039] Thus, after the flexible skin is pressed tightly over the outer periphery of the steering wheel frame, the flexible skin can be further pressed downwards by the upper pressing component 40 and upwards by the lower pressing component 50, thereby pressing the flexible skin tightly over both the upper and lower surfaces of the steering wheel frame. Therefore, the flexible skin achieves a tight, secure coverage of the steering wheel frame with good coverage, reducing the likelihood of bulges and wrinkles, and resulting in high coverage efficiency.

[0040] In other words, when the present invention is processed using the processing equipment 100 for steering wheel covering as described above, the processing method includes the following steps:

[0041] S10: The steering wheel frame with the pre-adheded flexible skin is placed on the support plate 20.

[0042] S20: The flexible skin is pressed radially against each other by moving the plurality of clamping molds 31 toward each other along the radial direction of the steering wheel frame, so that the flexible skin is pressed and covers the outer peripheral surface of the steering wheel frame.

[0043] S30: The flexible skin is pressed upward by the lower pressing component 50 so that the flexible skin is pressed tightly and covers the upper surface of the steering wheel frame.

[0044] S40: The lifting drive 60 drives the support plate 20 to rise, causing the clamping mold 31 and the lower pressing component 50 to move upward and approach the upper pressing component 40, thereby causing the upper pressing component 40 to press the flexible skin downward, and thus causing the flexible skin to be pressed and covered on the lower surface of the steering wheel frame.

[0045] Preferably, the processing method further includes holding the flexible skin, which is pressed radially, upwards, and downwards, under pressure for a period of time, thereby allowing the flexible skin to better conform to the steering wheel frame and thus better avoid wrinkles and bulges. Further, the pressure holding time can be 30 seconds.

[0046] According to some preferred embodiments of this utility model, see [link / reference]. Figure 1 and Figure 2 Each clamping member 30 further includes a clamping base 32, a clamping slide rail 33, and a clamping cylinder 34. The clamping base 32 is disposed on the support plate 20. The clamping slide rail 33 is disposed on the clamping base 32 and extends radially, and the clamping mold 31 is slidably disposed on the clamping slide rail 33 to move radially. The clamping cylinder 34 is connected to the clamping mold 31 and is used to drive the clamping mold 31 to slide. Thus, when the clamping cylinder 34 drives the clamping mold 31 to slide along the clamping slide rail 33, the clamping mold 31 moves radially along the steering wheel frame, and the multiple clamping molds 31 can clamp the steering wheel frame and press the flexible skin radially.

[0047] Figure 3 This is a cross-sectional view of the clamping mold 31 according to an embodiment of the present invention. Figure 3 The steering wheel frame has a turntable, and the clamping mold 31 has an inner curved surface 3101 adapted to conform to the outer peripheral surface of the turntable. In this way, when the clamping mold 31 contacts the flexible skin, the inner curved surface 3101 of the clamping mold 31 can conform to the outer peripheral surface of the turntable, thereby ensuring that the flexible skin gradually conforms to the outer peripheral surface of the turntable during the wrapping process, without bulging or wrinkling.

[0048] Furthermore, the clamping mold 31 is provided with a heating source for heating the clamping mold 31. In this way, when the flexible skin is pressed radially, upward and downward, the processing equipment 100 for steering wheel wrapping can also uniformly heat each part of the flexible skin while the inner curved surface 3101 is attached to the outer peripheral surface of the flexible skin. Uniform heating is beneficial to improving the curing efficiency of the adhesive between the flexible skin and the steering wheel frame and makes it easier to ensure that the adhesive in each part cures uniformly. This avoids bulging and wrinkling of the steering wheel after the flexible skin is pressed due to prolonged static placement or uneven and inefficient heating, which may be caused by prolonged static placement or uneven heating. This is beneficial to improving both the wrapping efficiency and the wrapping quality of the steering wheel frame.

[0049] Furthermore, the heating source can be a heating cavity 3102 formed within the clamping mold 31 and adapted to accommodate hot fluid, or an electric heating wire provided in the clamping mold 31, or an infrared heater for emitting infrared rays to the clamping mold 31, etc. Specifically, the present invention uses a heating cavity 3102 for heating, which helps to ensure that the inner curved surface 3101 of the clamping mold 31 can be uniformly heated, thereby helping to ensure that the clamping mold 31 heats the steering wheel frame uniformly and efficiently.

[0050] Figure 4 This is a schematic diagram of the upper pressing component 40 according to an embodiment of the present invention. Figure 5 yes Figure 1 An enlarged view of section A. (See attached diagram) Figure 1 , Figure 4 and Figure 5 The upper clamping assembly 40 includes a locking member 41 and an upper clamping member 42. The locking member 41 is disposed on the device body 10. The upper clamping member 42 is located above the locking member 41 and is rotatably disposed on the device body 10 to switch between a clamping position and an open position. When in the clamping position, the upper clamping member 42 covers the area between the plurality of clamping members 30 and cooperates with the locking member 41 to be locked. When in the open position, the upper clamping member 42 no longer covers the area between the plurality of clamping members 30 and is no longer locked.

[0051] Thus, when the upper clamping member 42 is in the open position, since the upper clamping member 42 no longer covers the area between the multiple clamping members 30, it is convenient to place the steering wheel frame between the multiple clamping members 30. When the upper clamping member 42 is flipped down from the open position to the clamping position, since the upper clamping member 42 covers the area between the multiple clamping members 30 and the upper clamping member 42 is locked and can no longer move, when the support plate 20 rises, the upper clamping member 42 can approach the gradually rising flexible skin and press the flexible skin downward.

[0052] According to some preferred embodiments of the present invention, see [reference]. Figure 1 , Figure 4 and Figure 5 The upper clamping member 42 is provided with a locking rod 421, and the locking rod 421 has an annular locking groove 42101 formed on its circumferential surface. The locking member 41 includes a locking base 411, a locking slide rail 412, a locking component 413 and a locking cylinder 414.

[0053] The locking base 411 is disposed on the device body 10. The locking slide rail 412 is disposed on the locking base 411. The locking member 413 is slidably disposed on the locking slide rail 412. The locking member 413 has a locking port 41301 with a side opening. When sliding, the locking member 413 is adapted to be installed in the locking groove 42101 through the locking port 41301 to lock the locking rod 421. The locking cylinder 414 is connected to the locking member 413 and is used to drive the locking member 413 to slide.

[0054] Thus, when the upper pressing member 42 is flipped downward to the pressing position, the locking cylinder 414 drives the locking member 413 to slide along the locking slide rail 412, thereby causing the locking port 41301 to approach the locking rod 421, and then the locking rod 421 enters the locking port 41301 through the side opening, and the locking member 413 is installed in the locking groove 42101, thereby the locking member 41 locks the upper pressing member 42.

[0055] Further, see Figures 2 to 4 When the plurality of clamping dies 31 are close together, they form clamping holes 301 suitable for fitting onto the outer periphery of the steering wheel frame. The upper clamping member 42 includes an upper clamping die 422 and a flip cover 423. The flip cover 423 is flip-mounted on the device body 10. The upper clamping die 422 is located on the flip cover 423, and the upper clamping die 422 forms a downwardly opening upper clamping groove 42201, which is adapted to align with the clamping holes 301 as the flip cover 423 flips. Thus, the upper clamping die 422 can conveniently press the steering wheel frame clamped by the plurality of clamping dies 31 downwards.

[0056] According to some preferred embodiments of the present invention, see [reference]. Figure 4The upper clamping assembly 40 further includes a drive motor 43, a tilting shaft 44, and a reducer 45. The tilting shaft 44 is rotatably mounted on the main body 10 of the device and is connected to the upper clamping member 42. The reducer 45 is connected to both the drive motor 43 and the tilting shaft 44. The drive motor 43 is adapted to drive the tilting shaft 44 to rotate via the reducer 45, thereby causing the upper clamping member 42 to tilt. Thus, when the drive motor 43 starts, the rotational motion output by the drive motor 43 is reduced by the reducer 45 and drives the tilting shaft 44 to rotate. The rotation of the tilting shaft 44 causes the upper clamping member 42 to tilt, thereby enabling the upper clamping member 42 to tilt smoothly under the drive of the drive motor 43.

[0057] According to some preferred embodiments of the present invention, see [reference]. Figure 2 The lower clamping assembly 50 includes a lower clamping mold 51 and a clamping cylinder 52. The lower clamping mold 51 is located below the clamping mold 31. The clamping cylinder 52 is connected to the lower clamping mold 51 and is used to drive the lower clamping mold 51 to press the flexible skin upward. Thus, after the multiple clamping molds 31 have radially pressed and clamped the flexible skin, the clamping cylinder 52 can drive the lower clamping mold 51 to rise, thereby bringing the lower clamping mold 51 into contact with the flexible skin, and thus enabling the lower clamping mold 51 to press the flexible skin upward.

[0058] Furthermore, the lower clamping mold 51 is formed with a through hole 5101 in the vertical direction, which is suitable for fitting onto the outside of the steering wheel frame, thereby ensuring that the lower clamping mold 51 can move smoothly in the vertical direction.

[0059] According to some preferred embodiments of the present invention, see [reference]. Figure 1 The lifting drive component 60 includes multiple lifting cylinders, which are located on the main body 10 of the equipment and connected to the support plate 20, for driving the support plate 20 to lift.

[0060] According to some preferred embodiments of the present invention, see [reference]. Figure 2 The processing equipment 100 for steering wheel wrapping also includes a positioning seat 70. The positioning seat 70 is disposed on the support plate 20, and the positioning seat 70 has a positioning post 71 adapted to be inserted into the inner hole of the steering wheel frame. Thus, when the steering wheel frame with a pre-adheded flexible skin is placed on the support plate 20, the positioning post 71 on the positioning seat 70 can be inserted into the inner hole of the steering wheel frame, thereby supporting and positioning the steering wheel frame.

[0061] Furthermore, the positioning seat 70 is equipped with a sensing sensor to detect whether the steering wheel frame is installed on the positioning seat 70. This facilitates determining whether the steering wheel frame is properly installed, helping to prevent the machine from idling.

[0062] Specifically, when the steering wheel frame is an aluminum alloy frame, the sensing sensor can be an eddy current sensor. The eddy current sensor can accurately measure the relative position between the metal conductor of the object being measured and its probe end face through the principle of eddy current effect, thereby determining whether the aluminum alloy frame is installed on the positioning seat 70.

[0063] Below, in conjunction with Figures 1 to 5 The specific working process of the processing equipment 100 for steering wheel wrapping according to a specific embodiment of the present invention is described in detail below:

[0064] 1) With the upper clamping member 42 in the open position, the steering wheel frame with the pre-adhesive flexible skin is inserted into the positioning post 71 of the positioning seat 70.

[0065] 2) The clamping cylinder 34 drives the clamping mold 31 to move along the clamping slide rail 33 toward the direction close to the steering wheel frame, thereby radially pressing the flexible skin and clamping the steering wheel frame, so that the circumferential surface of the flexible skin is pressed and covered to cover the outer circumferential surface of the steering wheel frame.

[0066] 3) The lower pressing mold 51 is driven to rise by the pressing cylinder 52, thereby pressing the flexible skin upward, and thus pressing the lower surface of the flexible skin to cover the lower surface of the steering wheel frame.

[0067] 4) The drive motor 43 drives the flip shaft 44 to rotate, thereby causing the flip cover 423 to flip downward, so that the upper pressing mold 422 on the flip cover 423 is aligned with the steering wheel frame, and during this process, the locking rod 421 flips downward accordingly.

[0068] 5) The locking member 413 is driven to slide along the locking slide rail 412 by the locking cylinder 414, thereby driving the locking member 413 to be installed in the annular locking groove 42101 through the locking port 41301, thereby locking the upper pressing mold 422 and making the upper pressing mold 422 immovable.

[0069] 6) The bearing plate 20 is driven to rise by the clamping cylinder 52, thereby causing the steering wheel frame clamped by the clamping mold 31 and the lower clamping mold 51 to rise and approach the upper clamping mold 422, thereby causing the locked upper clamping mold 422 to press down on the flexible skin, thereby causing the upper surface of the flexible skin to press and cover the upper surface of the steering wheel frame.

[0070] 7) While maintaining pressure on the steering wheel frame that is pressed radially, upward and downward, the heating chamber 3102 in the clamping mold 31 heats the steering wheel frame for 30 seconds, thereby enabling the flexible skin to complete the pressing and covering of the steering wheel frame.

[0071] Therefore, the steering wheel surface obtained through the above steps is flat, without bulges or wrinkles, and the flexible skin is firmly covered and not easy to fall off.

[0072] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments; any variations or modifications can be made to the implementation of the present invention without departing from these principles.

A processing method, characterized in that, The steering wheel frame pre-attached with the flexible skin is processed using the processing equipment described in any one of claims 1 to 7, the processing method comprising the following steps: The steering wheel frame with the pre-adheded flexible skin is placed on the support plate; The flexible skin is pressed radially against each other by moving multiple clamping molds along the radial direction of the steering wheel frame, so that the flexible skin is pressed tightly to cover the outer peripheral surface of the steering wheel frame; The flexible skin is pressed upward by the lower pressing component, so that the flexible skin is pressed tightly and covers the upper surface of the steering wheel frame; The lifting drive unit drives the support plate to rise, which in turn drives the clamping mold and the lower pressing assembly to move upward toward the upper pressing assembly, thereby causing the upper pressing assembly to press the flexible skin downward, and thus pressing the flexible skin to cover the lower surface of the steering wheel frame. Maintain the simultaneous radial, upward, and downward pressure for a certain period of time to ensure pressure retention.
