The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Combination Figure 1-6 This embodiment discloses a semi-automatic lock body assembly machine, which aims to solve the problems of manual operation, low production efficiency and unstable product quality in the production of general lock bodies in the prior art.

[0030] The lock assembly machine includes a frame 1, which is assembled from aluminum alloy profiles and metal panels in a box-like structure. The frame 1 has adjustable height feet at the bottom for stable support. It also has wheels at the bottom for easy transport or relocation. The frame 1 primarily serves a load-bearing and supporting function.

[0031] The top of the frame 1 is equipped with a large horizontal plate, on which is a "U"-shaped return mechanism 2. The return mechanism 2 is used to support several tooling trays 21 through four horizontal linear tracks. The tooling trays 21 are used to tool the parts to be assembled. The initial position is placed on the tooling tray 21 by the manual locking body base plate, and the tooling tray 21 is held and fixed by the pressure bar on one side of the tooling tray 21. Then the tooling tray 21 moves step by step to perform the assembly process one by one.

[0032] Specifically, along the transport direction of the return mechanism 2, the following are sequentially arranged: a knob feeding mechanism 3, a knob plate feeding mechanism 4, a knob flipping mechanism 6, a knob transporting mechanism 7, a torsion spring feeding mechanism 5, a torsion spring detection mechanism 8, an oiling mechanism 9, a cover feeding mechanism 10, a screw locking mechanism 11, a detection mechanism 12, and a discharge mechanism. The knob feeding mechanism 3 is used to supply knobs. It should be noted that in this embodiment, the knob feeding mechanism 3 can simultaneously supply two knobs to the two knob posts 23 on the worktable. At this time, the two knobs are in the same direction, and then the outer knob is flipped and transported. The knob plate feeding mechanism 4 is used to supply knob plates. The knob plates are transferred to the top of the knob located on the inner knob post 23 on the tooling tray 21. Then, the outer knob is flipped and transported and pressed onto the knob plate. The torsion spring feeding mechanism 5 is used to supply torsion springs and transfer them to the threshold assembly position. The torsion spring detection mechanism 8 is used to detect whether the assembly state of the torsion spring is qualified. The oiling mechanism 9 is connected to an external oil supply system and is used to add lubricating oil to the lock body threshold position. The cover feeding mechanism 10 includes a stacking tray and a transfer device for supplying the cover. The screw locking mechanism 11 is used to fasten and lock the cover and the lock body base plate. The testing mechanism 12 is used to perform functional testing on the product. In this embodiment, the testing mechanism 12 includes a turntable, and the outer circumference of the turntable is provided with a functional testing module and a latch detection module. The functional testing module includes a pressing testing mechanism for pressing the cover plate and a latch detection structure for testing the latch. In this embodiment, the lock body process is produced in one go, and multiple performance tests are completed simultaneously. The finished product is also inspected for quality, resulting in a high degree of automation in the entire production line, significantly improving production efficiency, facilitating mass production and full inspection of lock bodies, and ensuring product quality. The testing mechanism 12 is existing technology. Its specific structure and working principle can be found in relevant content in patents such as CN115179037B, and will not be repeated here. Those skilled in the art can select and implement it from existing technologies based on actual operational conditions. The output end of the turntable is equipped with a feeding mechanism, which includes a good product discharge mechanism 13 and a defective product discharge mechanism 14. The knob feeding mechanism 3, knob plate feeding mechanism 4, and torsion spring feeding mechanism 5 are respectively equipped with a vibratory feeder, a linear vibration track, and a transfer robot. The specific mechanical structures of the above mechanisms are all existing technologies. Their specific structures and working principles can be found in relevant content and details in patents such as CN117733549A and CN115179037B, and will not be repeated here. Those skilled in the art can select and implement it from existing technologies based on actual operational conditions.

[0033] In this embodiment, a plurality of tooling discs 21 are movably connected to the reflux mechanism 2, and the reflux mechanism 2 is provided with a stepping drive structure (stepping belt and cylinder push rod at the corner) to control the movement of the tooling discs 21.

[0034] Furthermore, in combination Figure 3 The tooling tray 21 is provided with two knob posts 23 for positioning knobs. The output end of the knob feeding mechanism 3 can simultaneously transfer two knobs to the two knob posts 23. The knob flipping mechanism 6 is used to flip the right knob at the original knob post 23. The knob transport mechanism 7 is used to transport the flipped knob to the left knob post 23.

[0035] The tooling tray 21 has a "V"-shaped positioning groove 22 on its side; the return mechanism 2 has a positioning member 24 adapted to the positioning groove 22 on its side, and the positioning member 24 has a movable insert structure that can move closer to or further away from the positioning groove 22. Correspondingly, the side of the insert structure away from the positioning groove 22 is connected to a linear drive (cylinder), which allows the tooling tray 21 to be kept in a stable position when it moves to the threshold position by using the cooperation of the positioning member 24 and the positioning groove 22, thereby ensuring the stability and accuracy of the automated assembly operation.

[0036] Additionally, the reflux mechanism 2 is provided with a feeding platform on one side, with an opening at the top and a side baffle at the edge, which is beneficial for temporary feeding during manual operation.

[0037] like Figure 5 As shown, the knob flipping mechanism 6 includes a first support 61 connected to the frame 1. A first slider 62 is mounted on the first support 61. A linear module is connected to the first slider 62, which controls the slider 62 to slide up and down. A first rotary cylinder 63 is connected to the outside of the first slider 62. The rotation axis of the first rotary cylinder 63 is horizontally positioned. The output of the first rotary cylinder 63 is connected to a pneumatically controlled first gripper 64, which is used to grip the knob to be flipped. During operation, the first gripper 64 rotates and grips the knob, causing the first slider 62 to move upwards, thus freeing the knob from the constraint of the knob post 23. The first rotary cylinder 63 drives the gripper to rotate and flip the knob 180 degrees, thus flipping the knob. Subsequently, the first slider 62 moves downwards, cooperating with the first gripper 64 to return the flipped knob to its original position.

[0038] like Figure 6As shown, the knob handling mechanism 7 includes a second bracket 71 connected to the frame 1. A second slider 72 is provided on the second bracket 71. The second slider 72 is driven by a transverse cylinder, which can drive the second slider 72 to slide laterally back and forth. A third slider 73 is connected to the outside of the second slider 72. The third slider 73 is driven by a lifting cylinder, which can drive the third slider 73 to slide up and down back and forth. A second rotary cylinder 75 is provided on the third slider 73. The rotation axis of the second rotary cylinder 75 is vertical. The output end of the second rotary cylinder 75 is connected to a pneumatically controlled second gripper 76, which is used to hold the knob to be handled. During operation, the third slider 73 moves downward, and the second gripper 76 clamps the flipped knob. The third slider 73 moves upward, causing the knob to break free from the constraint of the knob post 23. The second slider 72 moves laterally closer to the inner knob post 23. During this process, the second rotary cylinder 75 adjusts the angle of the gripper and the knob appropriately. The third slider 73 moves downward, and the second gripper 76 places the knob on top of the knob piece, completing the stacking assembly.

[0039] This invention significantly improves the efficiency of lock body assembly and reduces labor costs through automated and intelligent design. It reduces manual operation steps, effectively improving product quality consistency and stability. The rational structural design and tight fit between components ensure smooth assembly. By using a single-pass, double-feed knob feeding method, this invention eliminates one feeding mechanism compared to traditional equipment, resulting in a highly refined device structure. Combined with the knob flipping mechanism 6, the knob conveying mechanism 7, and the matching double knob posts 23, it further enhances assembly efficiency.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
