Technical Field

[0001] This utility model relates to the field of automation device technology, and in particular to a magazine self-locking mechanism and a magazine. Background Technology

[0002] With the development of modern industry, automated production is playing an increasingly important role in production. In automated production and non-standard automated processing or assembly lines, in order to facilitate the precise assembly of products and improve production efficiency, especially in the case of mass production, when high productivity is required and machine time is short, feeding is a repetitive and heavy operation. It often requires a feeding mechanism to provide parts to be processed or parts to be assembled. Among them, the clip-type feeding system is a commonly used one.

[0003] The following problems arise during the use of magazine-type feeding systems: Ordinary feeding magazines are generally open-type, allowing robotic arms or other feeding devices to directly supply parts to production assembly. However, during transportation, parts may slip out of the magazine, resulting in damage or loss. This type of feeding magazine poses certain safety hazards in automated production operations. Therefore, improvements to the safety of this type of feeding magazine are urgently needed. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example

[0025] Reference Figure 1 , 2 As shown, this utility model discloses a magazine self-locking mechanism, comprising: a movable block 1, a locking element 2, a connecting rod 3, a swing rod 4, and a pressure rod 5. The movable block 1 is capable of linear movement and is equipped with the locking element 2, which restricts the movable block 1 to a fixed position. The connecting rod 3 is hinged to the movable block 1. The swing rod 4 rotates around an axis at one end, and the other end of the connecting rod 3 away from the movable block 1 is hinged to the middle position of the swing rod 4. The other end of the swing rod 4 away from rotating around the axis is connected to the pressure rod 5. The movement of the movable block 1 is transmitted through the connecting rod 3 and the swing rod 4 to drive the pressure rod 5 to rotate around the axis. By moving the movable block 1, the connecting rod 3 and the swing rod 4 are driven to rotate, causing the pressure rod 5 to swing around the axis. When the pressure rod 5 rotates to the magazine's outlet position, it prevents parts from slipping out of the magazine's outlet.

[0026] In the above structure, the pressure rod 5 is rotated by manually moving the movable block 1. Further designed, a tension spring 6 is connected to the movable block 1, with one end connected to the movable block 1 and the other end fixed. The tension spring 6 is used to pull the movable block 1 back to its original position. With the added tension spring 6, after releasing the locking element 2, the tension spring 6, under its elastic restoring force, pulls the pressure rod 5 to rotate to the magazine's outlet position, thus automatically closing the magazine's outlet. Because of the tension spring 6, even without external force on the movable block 1, the tension spring 6 can pull the pressure rod 5 to the magazine's outlet position, achieving the closure of the magazine's outlet.

[0027] Preferably, the locking element 2 is an indexing pin. Inserting the locking element 2 into different positions of the magazine can push the pressure rod 5 to rotate to the open position.

[0028] In the above structure, the self-locking mechanism further includes a linear slide rail 7 and a slider 8. The slider 8 is connected to the movable block 1, and is mounted on the linear slide rail 7, allowing it to slide along the linear slide rail 7. The linear slide rail 7 has the same direction of elastic contraction or extension as the tension spring 6. Pushing the movable block 1 along the linear slide rail 7 enables the linear movement of the movable block 1.

[0029] In the above structure, the pressure rod 5 is a cylindrical rod, and both ends of the pressure rod 5 are connected to a rocker arm 4. By providing rocker arms 4 at both ends of the pressure rod 5, the stability of the pressure rod 5 during rotation is improved.

[0030] Additionally, the movable block 1 is provided with a tension spring fixing member 9, and one end of the tension spring 6 hooks onto the tension spring fixing member 9. The tension spring fixing member 9 is provided with a spring hole, and one end of the tension spring 6 is hooked into the hole on the tension spring fixing member 9. Example

[0031] Reference Figure 3-5 As shown, a magazine of this utility model includes: a hopper frame 10 and two symmetrically arranged opening and closing components 20. The opening and closing components 20 are mounted on the hopper frame 10. The pressure rods 5 of the two symmetrically arranged opening and closing components 20 are arranged in a double-door configuration at the outlet of the hopper frame 10, and the pressure rods 5 of the two symmetrically arranged opening and closing components 20 are used to open or close the outlet of the hopper frame 10. The opening and closing components 20 are the magazine self-locking mechanism. The hopper frame 10 is a frame as a whole, and one side of the hopper frame 10 is the outlet of the parts. The double-door structure of the two symmetrically arranged opening and closing components 20 is used to open or close the outlet of the hopper frame 10. When the outlet of the hopper frame 10 is closed, the parts can be stably confined within the hopper frame 10. When the outlet of the hopper frame 10 is open, the parts can be retrieved through the outlet of the hopper frame 10.

[0032] In the above structure, the hopper frame 10 is provided with at least one locking hole 101, which is used to lock and fix the locking element 2. Multiple locking holes 101 can be provided on the hopper frame 10 to facilitate the insertion of the locking element 2 into different locking holes 101.

[0033] In the above structure, the hopper frame 10 is provided with a tension spring fixing member 2 102, and the other end of the tension spring 6 is connected to the tension spring fixing member 2 102.

[0034] In addition, one end of the swing arm 4 is connected to the hopper frame 10 via a rotating shaft. The end of the swing arm 4 away from the pressure rod 5 is connected to the hopper frame 10 via a rotating shaft. Thus, when the movable block 1 moves, the swing arm 4 is driven to rotate around the rotating shaft via the connecting rod 3. That is, the pressure rod 5 makes a circular motion with the rotating shaft connecting the swing arm 4 and the hopper frame 10 as the center.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
