Description

Technical Field

[0001] The present application relates to the technical field of lock core processing, and in particular to a feeding conveyor for lock cores. Background Art

[0002] The lock cylinder includes a shell; the lock cylinder: has structures such as pins or rotating plates inside, which are used to match the key. Pins (or rotating plates): located inside the lock cylinder. The position of the pins will vary depending on the shape of the key. When the correct key is inserted, the pins will be pushed to the correct position, allowing the lock cylinder to rotate. Spring: used to provide pressure to the pins to ensure that they remain in the proper position. Dowel pin: helps fix the lock cylinder to prevent it from rotating at will. When the lock cylinder is processed, the pins and springs need to be inserted into the channel of the shell. Usually this process requires the shell to be positioned, and then each component is placed in the shell channel in turn.

[0003] In order to adapt to the external parts delivery system, gravity is used to deliver parts, and the lock cylinder shell needs to be placed vertically. However, since the bottom structure of the lock cylinder is a cylindrical structure, it requires external structure assistance during placement. The existing method usually uses a clamp to clamp it, and uses a multi-station collaborative method to deliver parts. Clamping at the initial station, different parts are delivered and end caps are screwed on at subsequent stations, and then sent out by a robotic arm at the final station. This requires a large system organization and increases the cost investment. Therefore, to solve the above problems, the present application provides a loading conveyor for lock cylinders.

[0027] The following is combined with Figure 1 - Figure 6 This application is described in further detail.

[0028] Example 1:

[0029] A feeding conveyor for lock cylinder, referring to Figure 1 - Figure 6 , including a guide frame 1 for guiding the lock cylinder housing, and a conveyor belt 4 is provided below the guide frame 1. The guide frame 1 is covered on the outside of the lock cylinder housing to stabilize the axial position of the lock cylinder and the vertical direction of the lock cylinder. Preferably, four guide frames 1 are provided, two of which are located on both sides of the vertical section of the lock cylinder housing, and the other two are located on the outside of the cylindrical section to support the lock cylinder housing. There is no restriction on the specific position of the guide frame 1, as long as the lock cylinder can be stabilized in the axial and vertical directions, thereby ensuring that the upper opening thereof can correspond to the subsequent parts delivery device;

[0030] The guide frame 1 is a strip-shaped structure with two locked sections, and a ball 14 protruding from the guide frame 1 is movably connected between the two sections, and the ball 14 is fitted to the outer wall of the lock core shell; the guide frame 1 includes a bottom plate 11 and a top plate 12 that are fixed to each other with bolts, and a groove 111 is provided on the bottom plate 11, and a groove 2 121 is provided on the top plate 12. The ball 14 is embedded between the groove 111 and the groove 2 121 of the same group, and the ball 14 passes through the groove 111 and extends to the outside thereof. The ball 14 can also be designed to pass through the groove 2 121, but passing through the groove 111 can achieve fit with the inner lock core shell, reducing the friction during the movement of the lock core shell. The bottom plate 11 and the top plate 12 can both be plate-shaped structures, or the bottom plate 11 can be a plate-shaped structure, and the top plate 12 can be an n-shaped cover plate structure. The main purpose of the two-section structure is to stabilize the position of the ball 14 and at the same time provide convenience for subsequent adjustment.

[0031] An adjustment structure 5 for adjusting the radius of the inscribed circle is provided on the outside of the guide frame 1. The adjustment structure 5 includes a swivel 52 fixedly connected to the top plate 12, a knob 51 rotatably connected to the inside of the swivel 52, and a threaded ring 53 threadedly connected to the threaded section of the knob 51.

[0034] Conveyor belt 4 is evenly distributed with ridges 41, the horizontal sections of which cut into the inner side of the inscribed circle of guide frame 1. Ribs 41 are made of soft rubber to ensure good friction with the outer wall of the lock cylinder, thus preventing slippage during transmission. The inscribed circle of guide frame 1 is cut to ensure sufficient contact area with the outer wall of the lock cylinder, also to ensure transmission efficiency. Conveyor belt 4 is driven by a servo motor. Furthermore, the device should be equipped with a CCD camera system or other sensor to obtain more accurate information on the lock cylinder position and ensure the accuracy of part placement.
