Description

Technical Field

[0001] This utility model relates to the technical field of car door edging equipment, specifically to a multi-roller mechanism and edging equipment for concealed water cutting of car doors. Background Technology

[0002] Concealed water deflectors are a solution that "embeds" the traditionally exposed window sill sealing strips into the interior of the car door sheet metal through structural reconstruction and process innovation. While improving aesthetics, they also achieve better sealing and noise reduction performance, and have become a standard design feature in mid-to-high-end models.

[0003] In the manufacturing process of car doors, the inner window frame edging section is located within a closed cavity structure formed by the window frame, the inner door panel, and the outer door panel. This area has limited height and complex geometry, placing stringent requirements on the motion path and structural dimensions of the edging mechanism. Currently, the edging mechanisms used in this area primarily employ a linkage drive system. While this achieves some edging functionality, it reveals several inherent drawbacks in practical applications: existing edging mechanisms occupy a large amount of space. To achieve complex edging trajectories, the linkage system requires a large stroke and rotation space, which contradicts the confined installation environment of the inner window frame, leading to difficulties in mechanism layout and even necessitating compromises in product design, such as shortening the edging length or altering the window frame structure. Utility Model Content

[0004] This utility model addresses the spatial conflict issue that arises when existing edge-sealing mechanisms are used in the concealed water-cutting edge-sealing process of car door inner window frames. It provides a multi-roller mechanism and edge-sealing equipment for concealed water-cutting of car doors. The specific technical solution is as follows: A multi-roller mechanism for concealed water cutting in car doors includes: a mounting bracket connected to the moving end of a multi-axis robotic arm, the mounting bracket extending outward to form several sets of support legs; and several sets of rollers connected to the ends of the support legs, the axes of each set of rollers being parallel to form the same motion trajectory.

[0005] Furthermore, it also includes a mounting base connected to the motion end of the multi-axis robotic arm at the top, the bottom end of the mounting base being connected to a mounting bracket, the mounting bracket forming two sets of symmetrically distributed legs, and the legs being detachably connected to the rollers.

[0006] Preferably, the rollers include large rollers and small rollers, with the diameter of the large rollers being larger than that of the small rollers. The multi-axis robotic arm sequentially drives the large rollers and small rollers to perform edge-wrapping operations on the car door.

[0007] An edge-sealing device includes: a multi-roller mechanism; a door liner that matches the shape of a car door, the door liner being placed laterally on a fixed base; when the fixed base is locked to the door liner, a multi-axis robotic arm drives the outriggers to move in multiple directions relative to the edge-sealing of the car door, so that the rollers are tangent to the edge-sealing of the car door respectively.

[0008] Preferably, it also includes several integrated self-locking clamping cylinders connected to a fixed base. The integrated self-locking clamping cylinders are arranged around the door liner. The rotating end of the integrated self-locking clamping cylinder is connected to the rotating clamping block. The rotation trajectory of the rotating clamping block driven by the integrated self-locking clamping cylinder intersects with the door liner and the door.

[0009] Preferably, it also includes a horizontal clamping block connected to a fixed base, the horizontal clamping block moving horizontally relative to the door liner until it contacts the side of the door liner.

[0010] As can be seen from the above technical solution, this utility model has the following beneficial effects: This invention utilizes outward-extending support legs to drive rollers to perform edge-wrapping treatment relative to the water-cutting mechanism of the car door. This allows a multi-axis robotic arm to guide the rollers into the closed cavity structure of the car door for edge-wrapping. Simultaneously, the outward-extending support legs prevent interference between the rollers and the closed cavity, enabling the rollers to contact the concealed water-cutting mechanism of the car door without interference. This adapts to the narrow and confined installation environment of the inner window frame, thereby improving the flexibility of this invention. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] Example 1 As is known from common knowledge in the field, the door mold 25 is a special tooling mold used in automobile manufacturing to support, position and shape door panels. In this embodiment, the door mold 25 is attached to the outer side of the door 3 so that it applies support force to each point of the door 3; "water cutter" is short for "water cutter strip", and its formal name is "window sill trim strip" or "window frame sealing strip".

[0016] like Figure 1 and Figure 2 As shown, this embodiment is a multi-roller mechanism for a hidden water cutter in a car door, which includes: a mounting bracket 12 connected to the moving end 151 of a multi-axis robotic arm 15, the mounting bracket 12 extending outward to form several sets of support legs 13; and several sets of rollers 14 connected to the ends of the support legs 13, the axes of each set of rollers 14 being parallel to form the same motion trajectory.

[0017] Specifically, Figure 1 There are revolute joints at points E, D, and C, which gives the multi-axis robotic arm 15 three degrees of freedom. Its top end is connected to the free end of the six-axis robot by bolts, giving its moving end 151 six degrees of freedom. This allows the moving end 151 of the multi-axis robotic arm 15 to move freely in space, thereby driving the mounting bracket 12, the support leg 13, and the roller 14 to move freely in space. This ensures that the axial side of the roller 14 is always tangent to the water cut of the door 3, thus improving its edge-sealing effect.

[0018] Secondly, the center line of the mounting bracket 12 coincides with the axis of the moving end 151, forming several sets of support legs 13 outwards. This ensures that when the multi-axis robotic arm 15 moves the support legs 13 relative to the car door 3, the support legs 13 do not interfere with the car door 3. The length of the support legs 13 is determined according to the size of the car door 3 being produced. Furthermore, the ends of the support legs 13 and the rollers 14 are connected by bolts to form a rotatable and detachable connection. This allows the rollers 14 to rotate relative to the support legs 13 and to quickly separate from or connect with the support legs 13. This enables the multi-axis robotic arm 15 to drive the rollers 14 to make contact and tangent with the water-cutting surfaces of the car door 3, thereby ensuring that the rollers 14 do not interfere with the car door 3 during the water-cutting process, thus improving the protection of the car door 3 during the edging process.

[0019] Secondly, the outriggers 13 extending in the same direction are grouped together, and the axis of the rollers 14 connected to the end of the outriggers 13 in the same group is parallel. This allows the rollers 14 in the same group to perform bending and edge-wrapping treatment on the same water cutter at the same time when the multi-axis robotic arm 15 drives the rollers 14 to perform edge-wrapping treatment. This reduces the number of rollers 14 that do not contact the water cutter during the edge-wrapping process, thereby simplifying the movement trajectory of the multi-axis robotic arm 15 driving the rollers 14 to move. It also reduces the possibility of interference between the rollers 14 that do not contact the water cutter and the door 3. At the same time, it can also improve the edge-wrapping effect by improving the space utilization of the rollers 14.

[0020] Furthermore, this embodiment also includes a mounting base 11 connected to the top end of the multi-axis robotic arm 15's motion end 151. The bottom end of the mounting base 11 is connected to a mounting bracket 12. The mounting bracket 12 forms two sets of symmetrically distributed support legs 13, and the support legs 13 are detachably connected to the rollers 14.

[0021] Specifically, the top of the mounting base 11 forms a mounting hole for the moving end 151 of the multi-axis robotic arm 15, so that the axis of the mounting base 11 coincides with the axis of the moving end 151. This ensures that when the moving end 151 drives the mounting base 11 to rotate, the mounting base 11 does not undergo eccentric movement. The bottom end of the mounting base 11 is fixedly connected to the center position of the mounting bracket 12 by bolts, ensuring that when the mounting base 11 drives the mounting bracket 12 to rotate, the mounting bracket 12 does not undergo eccentric rotation, thus avoiding increasing the complexity of the movement trajectory of the roller 14. Secondly, a single set of outriggers 13 is symmetrical about the vertical plane passing through the center line of the mounting bracket 12, and different sets of outriggers 13 are symmetrical about another vertical plane passing through the center line of the mounting bracket 12. This ensures that when the mounting bracket 12 drives the outriggers 13 and the rollers 14 to rotate, the rotation radius of all rollers 14 is equal, thereby reducing the complexity of the movement trajectory of the rollers 14 and reducing the possibility of interference with the door 3.

[0022] Secondly, the support leg 13 and the roller 14 are detachably connected by bolts, which allows the roller 14 to be quickly separated from or connected to the support leg 13, improving its replacement efficiency and thus expanding the applicability of this embodiment to the doors 3 of different car models.

[0023] Furthermore, the roller 14 includes a large roller 141 and a small roller 142. The diameter of the large roller 141 is larger than the diameter of the small roller 142. The multi-axis robotic arm 15 drives the large roller 141 and the small roller 142 in sequence to perform edge-wrapping work on the car door 3.

[0024] Specifically, when performing edge binding on the car door 3, the large roller 141 is rotatably connected to the support leg 13, and the multi-axis robotic arm 15 drives the large roller 141 to perform initial bending of the water cutter of the car door 3; next, the large roller 141 separates from the support leg 13, and the small roller 142 forms a rotatable connection with the support leg 13. The multi-axis robotic arm 15 drives the small roller 142 to perform extrusion edge binding on the water cutter of the car door 3 after initial bending. The small roller 142 has a small contact area with the water cutter, which allows it to perform edge binding more accurately and improve the edge binding quality.

[0025] Example 2 like Figure 3 As shown, this embodiment 2 is an edge-sealing device, which includes: a multi-roller mechanism; a door liner 25 that matches the shape of the door 3, the door liner 25 is placed horizontally on the fixed base 21, when the fixed base 21 and the door liner 25 are locked, the multi-axis robotic arm 15 drives the support leg 13 to move in multiple directions relative to the water cutter of the door 3, so that the roller 14 is tangent to the water cutter of the door 3 respectively.

[0026] Specifically, the door liner 25 is placed horizontally, and the fixed base 21 locks the door liner 25 with a clamping mechanism such as a cylinder or bolt, so that the two are relatively fixed. Next, the multi-axis robotic arm 15 drives the roller 14 to move within the space, and then makes tangential contact with the water-cutting surface of the upper surface of the door 3, and then performs bending and edge-wrapping treatment. Next, the multi-axis robotic arm 15 uses the outriggers 13 to push the roller 14 into the lower surface of the door 3, so that the roller 14 can make tangential contact with the water-cutting surface of the lower surface, and then perform bending and edge-wrapping treatment, while avoiding interference between the multi-roller mechanism and the door 3, and improving its flexible movement ability.

[0027] The lower surface of the door 3 refers to the side facing the fixed base 21, and its upper surface is the side away from the fixed base 21. A single door 3 has four sides that need to be edged, and adjacent sides are divided into two groups, which are processed by two multi-axis robotic arms 15 respectively.

[0028] In this second embodiment, the preferred embodiment of the edge-wrapping process for the car door 3 is as follows: the multi-axis robotic arm 15 uses a large roller 141 to perform a preliminary bending process along a single side edge, with a bending angle of 120°; next, the multi-axis robotic arm 15 uses a small roller 16 to perform a secondary bending process, with a bending angle of 30°; next, the multi-axis robotic arm 15 uses the small roller 16 to complete the water cutting and side edge-wrapping process of the car door 3.

[0029] like Figure 4 and Figure 5 As shown, this embodiment 2 also includes several integrated self-locking clamping cylinders 23 connected to the fixed base 21. The integrated self-locking clamping cylinders 23 are arranged around the door liner 25. The rotating end of the integrated self-locking clamping cylinder 23 is connected to the rotating clamping block 24. The rotation trajectory of the integrated self-locking clamping cylinder 23 driving the rotating clamping block 24 intersects with the door liner 25 and the door 3.

[0030] Specifically, the integrated self-locking clamping cylinder 23 is a commonly used product in this field. Its moving end 151 can swing, and the rotating clamping block 24 is connected to its moving end 151 by bolts, so that the rotating clamping block 24 can swing simultaneously with it. Secondly, the bottom of the integrated self-locking clamping cylinder 23 is fixedly connected to the fixed base 21 by bolts. Multiple integrated self-locking clamping cylinders 23 are arranged along the periphery of the door liner 25 and the periphery of the door 3. They are fixedly installed on the fixed base 21, so that they can drive the rotating clamping block 24 to rotate relative to the fixed base 21. The rotation trajectory intersects with the door liner 25 or the door 3, so that it can cooperate with the fixed base 21 to clamp the door liner 25 or the door 3, so that the door liner 25 and / or the door 3 does not move relative to the fixed base 21. Thus, when the multi-axis robotic arm 15 drives the roller 14 to move relative to the water-cutting of the door 3, the door 3 does not shift in position, thereby improving the positional accuracy of the roller 14 and the door 3, and thus improving its edge-sealing quality.

[0031] Furthermore, it also includes a horizontal clamping block 22 connected to the fixed base 21, which moves horizontally relative to the door liner 25 until it contacts the side of the door liner 25.

[0032] Specifically, the horizontal clamping block 22 is slidably connected to the fixed base 21 via a cylinder and a slide rail, allowing the cylinder to push the horizontal clamping block 22 to move along the slide rail, thereby moving horizontally relative to the fixed base 21 and bringing it closer to the side of the door membrane 25. This allows it to work with the fixed base 21 to apply a lateral clamping force, thus horizontally limiting the door membrane 25. After the horizontal clamping block 22 has initially positioned the door membrane 25, the integrated self-locking clamping cylinder 23 drives the rotating clamping block 24 to clamp the door membrane 25, further constraining its position. Then, the door 3 is in contact with the door membrane 25, and part of the integrated self-locking clamping cylinder 23 drives the rotating clamping block 24 to clamp the door 3, thereby locking the door 3, door membrane 25, and fixed base 21 to maintain their relative fixation. This prevents any displacement of the three components when the roller 14 performs edge banding on the door 3, which would affect the edge banding and consequently the quality of the concealed edge banding.
