Description

Technical Field

[0001] This invention belongs to the field of automotive parts manufacturing technology, specifically relating to a roller pressing device for producing automotive sunroof guide rails. Background Technology

[0002] The sunroof guide rail is a key guiding component in the automotive sunroof system. Its cross-sectional shape is usually quite complex, requiring multiple roll forming processes. When producing the guide rail using a roll forming device, the formed guide rail bodies need to be collected, stacked, and transported for subsequent processing or assembly.

[0003] In existing technology, a common rolling device for producing automotive sunroof guide rails includes a rolling mechanism and a transport track for outputting the formed guide rails. However, the structural design of the guide rail body often has specific shape characteristics. For example, some guide rail bodies have a rectangular cross-section, with a small contact area between the upper and lower end faces, and both end faces have process notches. This structure causes the formed guide rail bodies to tilt easily due to external disturbances or slight shaking of the guide rail body itself when stacked, because there is a lack of sufficient stable contact surface between the upper and lower end faces. Once the lower layer of guide rail body tilts, the guide rail body above it will also tilt, resulting in the entire stack of guide rails scattering in batches, seriously affecting production efficiency and product yield.

[0004] To avoid the aforementioned stacking instability issues, the guide rail body is typically placed vertically with its side end face as the support surface. However, in the roll forming process, the guide rail body is usually laid flat (i.e., its upper and lower end faces are horizontal) for continuous processing. Therefore, after roll forming is completed, the guide rail body needs to be rotated 90 degrees from its flat position to a side-standing position to facilitate subsequent vertical stacking and transport.

[0005] In existing technologies, manual assistance is typically used to adjust the posture of the guide rail body. However, manual methods are labor-intensive and inefficient. The guide rail body produced by roll forming has not undergone deburring and chamfering processes, and it has some sharp edges or burrs that can easily cut hands. Therefore, this application proposes a roll forming device for the production of automotive sunroof guide rails. Summary of the Invention

[0006] The purpose of this invention is to provide a rolling device for producing automotive sunroof guide rails, to solve the problem of manually adjusting the posture of the guide rail body as mentioned in the background art. However, manual methods are labor-intensive and inefficient, and the guide rail body produced by rolling does not undergo deburring, chamfering, or other processes, resulting in sharp edges or burrs that can easily cut hands.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a roller pressing device for producing automotive sunroof guide rails, comprising a roller pressing mechanism and a transport track, wherein the transport track is used to transport the guide rail body; The transport track is equipped with a track positioning mechanism for clamping and releasing the guide rail body; The transport track is equipped with a rotating plate connected to the track positioning mechanism, a flip drive motor connected to the rotating plate, a movable frame for mounting the flip drive motor, and a movable mechanism connected to the movable frame. The flip drive motor is used to drive the guide rail body fixed by the track positioning mechanism to rotate. The transport track is provided with vertically distributed lower support plates, lifting plates for mounting on the lower support plates, lifting units connected to the lifting plates, and support frames for mounting the lifting units. Multiple lower support plates are provided, and the transport track includes rollers, with the lower support plates located between two adjacent rollers.

[0008] Preferably, the track positioning mechanism includes a lower pressure plate, an upper pressure plate, a positioning frame fixedly connected to the lower pressure plate and slidably engaged with the upper pressure plate, and a positioning drive unit mounted on the positioning frame.

[0009] Preferably, the upper pressure plate is provided with an insert plate on the side near the lower pressure plate, and the lower pressure plate is provided with a slot that mates with the insert plate.

[0010] Preferably, when the upper pressure plate and the lower pressure plate abut against each other, they form a storage groove for storing the guide rail body.

[0011] Preferably, a push-pull plate is provided at the upper pressure plate, the positioning drive unit is connected to the push-pull plate, the push-pull plate is set in a Z-shape, a lifting groove is provided in the positioning frame, the push-pull plate cooperates with the lifting groove, and the positioning drive unit is set at the side of the positioning frame.

[0012] Preferably, a support plate and a support rod are provided between the rotating plate and the track positioning mechanism, and the support plate is fixedly installed inside the track positioning mechanism.

[0013] Preferably, there are two support plates, which are symmetrically distributed about the center line of the rotating plate.

[0014] Preferably, each of the support plates is provided with three parallel support rods, which are fixedly connected to the rotating plate.

[0015] Preferably, the moving mechanism includes a threaded slider fixedly connected to the moving frame, a threaded rod threadedly connected to the threaded slider, a guide box rotatably engaged with the threaded rod and slidably engaged with the threaded slider, and a moving drive motor mounted on the guide box for driving the threaded rod to rotate.

[0016] Preferably, the moving mechanism is used to drive the track positioning mechanism to move forward or backward. Moving forward allows the track positioning mechanism to engage with the guide rail body, while moving backward allows the track positioning mechanism to separate from the guide rail body, and the separated guide rail body can fall onto the transport track.

[0017] Beneficial effects: This invention provides a roller pressing device for producing automotive sunroof guide rails. A flipping drive motor drives a rotating plate, a track positioning mechanism fixedly connected to the rotating plate, and a guide rail body fixed by the track positioning mechanism to rotate 90 degrees. A moving mechanism drives the track positioning mechanism to move forward or backward. Moving forward allows the track positioning mechanism to engage with the guide rail body, while moving backward allows the track positioning mechanism to separate from the guide rail body. A lifting unit can move a lower support plate up and down. After the track positioning mechanism drives the guide rail body to rotate, it drives the lower support plate to move upward, thus moving the lower support plate below the guide rail body. At this point, the track positioning mechanism separates from the guide rail body and can also support the transport track. Then, the lifting unit drives the lower support plate to fall, moving the guide rail body onto the transport track. This avoids the guide rail body falling directly from a height, and eliminates the need for direct human contact with the guide rail body, preventing injury from the guide rail body.

[0018] The present invention provides a roller pressing device for the production of automotive sunroof guide rails. By using support rods and support plates, a certain distance is maintained between the rotating plate and the track positioning mechanism. In this way, the fixed point of the track positioning mechanism can be located near the midpoint of the guide rail body. Compared with fixing only one end of the guide rail body, the entire guide rail body is supported more stably. Attached Figure Description

Detailed Implementation

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figures 1-8 As shown in the figure, an embodiment of the present invention provides a roller pressing device for producing automotive sunroof guide rails, including a roller pressing mechanism 1 and a transport track 2. The transport track 2 is used to transport the guide rail body 3, as can be seen from the figure. Figure 3 The guide rail body 3 is rectangular in shape. Its upper and lower surfaces have small contact areas and notches. When stacked, it is easy to tilt due to insufficient contact area or shaking of the guide rail body 3. Once the lower guide rail body 3 tilts, the guide rail body 3 above it will also tilt, which will cause the stacked guide rail bodies 3 to fall apart.

[0023] Because the upper and lower ends are not convenient to stack, the guide rail body 3 needs to be erected during transportation and placement, that is, its side end faces vertically downwards. This makes the stacked guide rail body 3 more stable. The upper and lower ends need to be formed by the roller pressing mechanism 1. Therefore, after the roller pressing mechanism 1 completes the forming of the guide rail body 3, its angle needs to be rotated by 90 degrees so that it can move vertically along the transport track 2. This facilitates the subsequent placement work. In order to allow the guide rail body 3 to rotate, a track positioning mechanism 4 is provided at the transport track 2. The track positioning mechanism 4 is used to clamp and release the guide rail body 3.

[0024] Specifically, the track positioning mechanism 4 includes a lower pressure plate 401, an upper pressure plate 402, a positioning frame 404 fixedly connected to the lower pressure plate 401 and slidably engaged with the upper pressure plate 402, and a positioning drive unit 407 mounted on the positioning frame 404. The positioning drive unit 407 may be a cylinder.

[0025] The positioning drive unit 407 can drive the positioning frame 404 to move up and down, thereby driving the upper pressure plate 402 to move up and down. The upper pressure plate 402 moves down and gets close to the lower pressure plate 401, which can press down the guide rail body 3 located between the upper pressure plate 402 and the lower pressure plate 401. When the upper pressure plate 402 is lifted up, the guide rail body 3 can be released.

[0026] More specifically, an insert plate 403 is provided on the side of the upper pressure plate 402 near the lower pressure plate 401, and a slot that mates with the insert plate 403 is provided in the lower pressure plate 401. When the upper pressure plate 402 abuts against the lower pressure plate 401, a storage groove for storing the guide rail body 3 is formed. It should be noted that a push-pull plate 405 is provided at the upper pressure plate 402, and the positioning drive unit 407 is connected to the push-pull plate 405. The push-pull plate 405 is Z-shaped, and a lifting groove 406 is provided in the positioning frame 404. The push-pull plate 405 mates with the lifting groove 406. The positioning drive unit 407 is located on the side of the positioning frame 404, not on the top of the positioning frame 404. This is to reduce the overall height of the positioning frame 404. In this way, when the entire guide rail body 3 is rotated, the distance between it and the transport rail 2 does not need to be too large. (During the rotation of the positioning frame 404 and the guide rail body 3, a certain distance needs to be left to avoid the positioning frame 404 colliding with the transport rail 2. The shortening of the overall height of the positioning frame 404 can reduce the distance between the two.)

[0027] It should be noted that the positioning drive unit 407 can be composed of a lead screw, a nut, and a motor. The lead screw and the nut rotate together, and the nut is connected to the upper pressure plate 402. The upper pressure plate 402 and the positioning frame 404 can only slide relative to each other up and down. The motor drives the lead screw to rotate, which in turn drives the nut and the upper pressure plate 402 to move up and down, thus realizing the fixing and loosening of the guide rail body 3.

[0028] In order to enable the track positioning mechanism 4 and the guide rail body 3 fixed thereto to rotate together, a rotating plate 7 connected to the track positioning mechanism 4, a flipping drive motor 8 connected to the rotating plate 7, a moving frame 9 for mounting the flipping drive motor 8, and a moving mechanism 10 connected to the moving frame 9 are provided at the transport track 2. The flipping drive motor 8 is used to drive the rotating plate 7, the track positioning mechanism 4 fixedly connected to the rotating plate 7, and the guide rail body 3 fixed by the track positioning mechanism 4 to rotate 90 degrees. The moving mechanism 10 is used to drive the track positioning mechanism 4 to move forward or backward. Moving forward allows the track positioning mechanism 4 to engage with the guide rail body 3, and moving backward allows the track positioning mechanism 4 to separate from the guide rail body 3. After separation, the guide rail body 3 can fall onto the transport track 2.

[0029] Specifically, a support plate 5 and a support rod 6 are provided between the rotating plate 7 and the track positioning mechanism 4. The support plate 5 is fixedly installed inside the track positioning mechanism 4, and there are two support plates 5. The two support plates 5 are symmetrically distributed about the center line of the rotating plate 7. Each support plate 5 is provided with three parallel support rods 6. The support rods 6 are fixedly connected to the rotating plate 7. Through the support rods 6 and the support plate 5, there is a certain distance between the rotating plate 7 and the track positioning mechanism 4. In this way, the fixed point of the track positioning mechanism 4 can be located near the midpoint of the guide rail body 3. Compared with fixing only one end of the guide rail body 3, the entire guide rail body 3 is supported more stably.

[0030] Specifically, the moving mechanism 10 includes a threaded slider 1001 fixedly connected to the moving frame 9, a threaded rod 1002 threadedly connected to the threaded slider 1001, a guide box 1003 rotatably engaged with the threaded rod 1002 and slidably engaged with the threaded slider 1001, and a moving drive motor mounted on the guide box 1003 for driving the threaded rod 1002 to rotate.

[0031] More specifically, the mobile drive motor and threaded rod 1002 can be replaced with a cylinder, which drives the threaded slider 1001 to move along the guide box 1003. Naturally, there is no need to set a corresponding threaded hole in the middle position of the threaded slider 1001.

[0032] In order to support the guide rail body 3 and prevent the guide rail body 3 from falling directly onto the transport track 2 after the track positioning mechanism 4 is pulled out, a vertically distributed lower support plate 11, a lifting plate 12 for mounting the lower support plate 11, a lifting unit 13 connected to the lifting plate 12, and a support frame for mounting the lifting unit 13 are provided at the transport track 2. The lifting unit 13 can be a cylinder. Multiple lower support plates 11 are provided. The transport track 2 includes rollers. The lower support plates 11 are located between two adjacent rollers. Multiple lower support plates 11 are evenly spaced and parallel.

[0033] The lifting unit 13 can drive the lower support plate 11 to move up and down. After the track positioning mechanism 4 drives the guide rail body 3 to rotate, it drives the lower support plate 11 to move up, and then moves the lower support plate 11 to below the guide rail body 3. At this time, the track positioning mechanism 4 separates from the guide rail body 3, and can also support the transport track 2. Then the lifting unit 13 drives the lower support plate 11 to fall, and can move the guide rail body 3 to the transport track 2. In this way, the guide rail body 3 is prevented from falling directly from a height.

[0034] Meanwhile, after the track positioning mechanism 4 drives the guide rail body 3 to rotate 90 degrees, the upper pressure plate 402 in the track positioning mechanism 4 moves upward, and then the lower bearing plate 11 moves upward, pushing the guide rail body 3 upward a certain distance. In this way, the guide rail body 3 can be separated from the track positioning mechanism 4. At this time, the moving mechanism 10 drives the track positioning mechanism 4 to move, and the track positioning mechanism 4 will not move with the guide rail body 3. In this way, the track positioning mechanism 4 and the guide rail body 3 can be separated smoothly.

[0035] In summary, this invention provides a roller pressing device for producing automotive sunroof guide rails. A flipping drive motor 8 drives a rotating plate 7, a track positioning mechanism 4 fixedly connected to the rotating plate 7, and a guide rail body 3 fixed by the track positioning mechanism 4 to rotate 90 degrees. A moving mechanism 10 drives the track positioning mechanism 4 to move forward or backward. Moving forward allows the track positioning mechanism 4 to engage with the guide rail body 3, while moving backward allows the track positioning mechanism 4 to separate from the guide rail body 3. A lifting unit 13 can move the lower support plate 11 up and down. After the track positioning mechanism 4 drives the guide rail body 3 to rotate, it drives the lower support plate 11 to move upward, thus moving the lower support plate 11 below the guide rail body 3. At this time, the track positioning mechanism 4 separates from the guide rail body 3, which can also support the transport track 2. Then, the lifting unit 13 drives the lower support plate 11 to fall, moving the guide rail body 3 onto the transport track 2, thus preventing the guide rail body 3 from falling directly from a height.

[0036] By using support rod 6 and support plate 5, a certain distance is maintained between rotating plate 7 and track positioning mechanism 4. This allows the fixed point of track positioning mechanism 4 to be located near the midpoint of guide rail body 3, making the entire guide rail body 3 more stable compared to fixing only one end of the guide rail body 3.

[0037] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
