Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to a tailgate lock cover assembly machine. Background Technology

[0002] Tailgate locks are key components that ensure the safe and reliable closing and opening of the rear doors of a vehicle (such as the trunk door, hatchback door, or liftgate). Existing tailgate locks can be found in Chinese patent documents with publication numbers CN214035181U or CN216949928U. With the development of the automotive industry and the increasing demand for convenience and security from users, tailgate lock technology is also constantly evolving.

[0003] In traditional manufacturing processes, car door locks are mostly assembled manually, which is not only inefficient but also makes it difficult to control the quality of the finished product. To address this, automated door lock assembly equipment has been emerging on the market. For example, the "Automatic Door Lock Assembly and Testing Machine" disclosed in Chinese patent document CN103586689A can achieve fully automated riveting of the riveting points on the door lock, thereby improving production efficiency and quality to a certain extent. However, this automated door lock assembly and testing machine cannot achieve automated assembly of the door lock outer cover (i.e., bottom cover and top cover), so the assembly efficiency of the door lock still cannot be maximized.

[0004] Therefore, it is necessary to provide a technical solution to address the above problems. Utility Model Content

[0005] This utility model provides a tailgate lock cover assembly machine, which aims to solve the problem that existing door lock assembly equipment cannot achieve automatic assembly of the door lock cover, resulting in the tailgate lock production efficiency not being maximized.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] In the description of the embodiments of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the embodiments of this utility model and simplifying the description, and does 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, it should not be construed as a limitation of this utility model.

[0035] To more clearly illustrate the technical solution of this utility model, a preferred embodiment is provided below for reference. Figures 1-5 A tailgate lock cover assembly machine, comprising:

[0036] The conveying device 1 and a plurality of clamping fixtures 100 disposed on the conveying device 1 are provided. The conveying device 1 is used to drive the plurality of clamping fixtures 100 to move along a specific path. The conveying device 1 may have a top cover loading station and a screw fastening station.

[0037] The upper cover feeding device 2 is used to assemble the upper cover onto the bottom cover placed on the clamping fixture 100;

[0038] The top cover screw-locking device 3 is used to lock screws at specific points on the top cover and bottom cover placed on the clamping fixture 100 to fix the top cover and bottom cover.

[0039] Unlike the traditional process where the bottom cover and top cover are assembled manually and then riveted together by a riveting machine, the tailgate lock top cover assembly machine described in this embodiment can achieve fully automatic assembly of the tailgate lock top cover without manual intervention. The working process of the tailgate lock top cover assembly machine of this utility model is as follows: a cavity adapted to the bottom cover is formed on the clamping fixture 100. The bottom cover can be easily placed into the cavity by a feeding mechanism or manually. Then, the conveying device 1 moves the clamping fixture 100 to the top cover feeding station. The top cover feeding device 2 can transport the top cover to the clamping fixture 100 at the top cover feeding station and precisely assemble the top cover and bottom cover. Next, the conveying device 1 moves the clamping fixture 100 to the screw-locking station. At this time, the top cover screw-locking device 3 can automatically lock the screws to the corresponding points to achieve the locking of the top cover and bottom cover to form the cover body. Compared with existing technologies, this tailgate lock cover assembly machine can automatically feed the cover and automatically tighten the screws, which not only improves the assembly efficiency of the tailgate lock, but also ensures the assembly quality of the tailgate lock.

[0040] In some embodiments, the conveying device 1 includes two conveyor lines arranged vertically and in opposite directions. Lifting and connecting mechanisms are provided at the ends of the two conveyor lines to transport the clamping fixture 100 from one conveyor line to the other, thereby enabling the cyclical movement of the clamping fixture 100. After the cover with screws on the clamping fixture 100 is removed, the conveying device 1 transports the clamping fixture 100 back to its initial position to clamp a new bottom cover and top cover for assembly. Alternatively, the conveying device 1 can also be circular, elliptical, racetrack-shaped, etc., as long as the clamping fixture 100 can move cyclically along a specific path.

[0041] In some embodiments, the top cover feeding device 2 includes a top cover storage bin 21 and a top cover conveying mechanism 22, which is used to install the top cover in the top cover storage bin 21 onto the bottom cover placed on the clamping fixture 100.

[0042] Preferably, the upper cover storage bin 21 includes a bin frame 211, which has a storage area 212 and a retrieval area 213. The storage area 212 contains several boxes stacked at intervals. The bin frame 211 is equipped with a tray assembly 214 capable of vertical and horizontal movement. The tray assembly 214 can move to the gap between any two boxes or to below the bottom box, thereby retrieving any box from the storage area 212 and transporting it to the retrieval area 213. This eliminates the need to stop the tailgate lock upper cover assembly machine to replenish boxes, improving production efficiency. It is understood that the tray assembly 214 can achieve horizontal and vertical movement using existing actuators such as cylinders or electric slides, which will not be elaborated upon here.

[0043] Preferably, the cover conveying mechanism 22 includes a first XYZ axis manipulator 221 and an automatic gripper 222 connected to each other. The first XYZ axis manipulator 221 can drive the automatic gripper 222 to move along the X-axis, Y-axis and Z-axis directions so that the automatic gripper 222 can grab the cover in the cover storage bin 21 and install it onto the bottom cover placed on the clamping fixture 100.

[0044] In some embodiments, at least two top cover screw-locking devices 3 are provided, and the at least two top cover screw-locking devices 3 sequentially screw the top cover to fix the top cover and the bottom cover. It is understood that there are usually multiple screw points on the top cover, such as 8 or 10, and the cooperation of two top cover screw-locking devices 3 can improve the screw-locking efficiency, avoid the clamping fixture 100 from being stuck in a certain position for too long, and improve production efficiency.

[0045] In some embodiments, the cover screw-locking device 3 includes a second XYZ axis robot 31 and a screw-locking station 32. The second XYZ axis robot 31 can drive the screw-locking station 32 to move along the X-axis, Y-axis and Z-axis directions so that the screw-locking station 32 can lock the screws onto the cover.

[0046] In some embodiments, the cover screw-locking device 3 further includes a height detection mechanism 33. The second XYZ axis robot arm 31 can drive the height detection mechanism 33 to move along the X, Y, and Z axes. The height detection mechanism 33 is used to detect the height of the screw points on the cover. Due to the shape design of the cover, the height of each screw point is different. Through the cooperation of the height detection mechanism 33 and the screw-locking station 32, the screw-locking station 32 can smoothly lock the screws to different points on the cover.

[0047] In some embodiments, the upper cover screw-locking device 3 further includes a clamping mechanism 34, which can clamp and fix the upper cover and the bottom cover placed on the clamping fixture 100. In this way, when the screw-locking station 32 delivers the screw to the screw-locking point of the cover or when the screw-locking station 32 locks the screw into the screw-locking point, relative movement between the upper cover and the bottom cover can be avoided, so that the screw-locking points of the upper cover and the screw-locking points of the bottom cover can be kept aligned, ensuring that the upper cover and the bottom cover can be locked smoothly.

[0048] In some embodiments, the clamping mechanism 34 includes a pressure plate 341 and a telescopic actuator 342, which drives the pressure plate 341 to move up and down. In practical applications, when the clamping fixture 100 moves to the screw-locking position, the telescopic actuator 342 drives the pressure plate 341 downward to press and fix the upper cover and bottom cover placed on the clamping fixture 100. After all the screws on the cover are locked, the telescopic actuator 342 drives the pressure plate 341 upward so that the clamping fixture 100 can continue to be conveyed by the conveying device 1.

[0049] In some embodiments, the tailgate lock cover assembly machine also includes a detection device for checking whether the components inside the bottom cover on the clamping fixture 100 are complete. When the detection device detects that the components on the bottom cover (such as bearings, damping plates, reduction gears, etc.) are not installed in place, the subsequent cover feeding device 2 will not install the cover onto the bottom cover, and the cover screw-locking device 3 will not perform the screw-locking process to fix the cover and the bottom cover, thereby avoiding material waste.

[0050] The above description is only a preferred embodiment of the present utility model, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
