Description

Technical Field

[0001] This invention relates to the field of magazine fixing technology, and in particular to a magazine fixing mechanism. Background Technology

[0002] In the electronics manufacturing industry, as the application scenarios of electronic products continue to expand, their manufacturing precision and process requirements are also constantly increasing, placing higher standards on the stability and compactness of various auxiliary mechanisms in the production process. As a key component used to hold, carry, and transport material trays in the electronics manufacturing process, the rationality of the magazine's fixing method directly affects the feeding stability, production efficiency, product quality, and overall operational stability of automated equipment. The core function of the magazine fixing mechanism is to reliably fix the magazine, ensuring that it maintains a precise position during automated feeding, thereby achieving stable and continuous feeding of automated equipment. Therefore, the optimized design of the magazine fixing mechanism has become a crucial aspect of improving the level of electronics manufacturing.

[0003] Currently, the magazine fixing structure used in electronic product manufacturing is mainly based on the cylinder gripper mechanism. While this type of mechanism can achieve the magazine fixing function, it has obvious technical drawbacks: First, the structural characteristics of the cylinder gripper mechanism determine that it occupies a large space, which is not conducive to the compact design of the overall structure of automated equipment and makes it difficult to adapt to the needs of miniaturized and integrated production equipment; Second, this mechanism requires the supporting pneumatic circuits, wiring, and other control components, resulting in a complex overall control structure. This not only increases the manufacturing cost of the equipment but also increases the difficulty and cost of maintenance. In addition, long-term operation of the pneumatic circuits and wiring may lead to leakage and malfunctions, affecting the stability of equipment operation.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide a magazine fixing mechanism that ensures reliable magazine fixing while being simple, compact, space-saving, and cost-effective.

[0006] The objective of this invention is achieved through the following technical solution: a magazine fixing mechanism, comprising: A base frame on which a base plate is provided, and at least one roller assembly is provided on the base plate; A drawer assembly, disposed on the base frame, includes a drawer plate for holding a magazine, the drawer plate being movable along the X-axis between a first position for picking up and placing the magazine and a second position for fixing the magazine; At least one clamping assembly corresponds to each of the roller assemblies. Each clamping assembly includes a mounting base and a clamping member. The mounting base is fixed to the drawer plate, and the clamping member is rotatably connected to the mounting base about the Y-axis. The clamping member has an open state and a clamped state. A first magnetic element is provided on the mounting base, and a second magnetic element is provided on the clamping member. The first magnetic element and the second magnetic element repel each other. The magazine has a clearance hole at its bottom along the Z-axis that corresponds to the clamping member. When the drawer plate moves from the first position to the second position, the roller assembly pushes against the clamping member to make it rotate to the clamping state, and the clamping member presses the magazine against the drawer plate through the clearance hole. When the drawer plate moves from the second position to the first position, the roller assembly disengages from the clamping member, and the clamping member rotates back to the released state to release the magazine under magnetic repulsion.

[0007] Furthermore, the clamping member is provided with a third magnetic element, and when the clamping member is rotated to the released state, the third magnetic element and the first magnetic element magnetically engage.

[0008] Furthermore, the clamping member is rotatably connected to the mounting base via a rotating shaft, one end of the clamping member is a pushing end for the roller assembly to push against, and the other end is formed with a hook; The magazine has an upper surface and a lower surface at its bottom. The clearance hole extends from the upper surface to the lower surface. When the clamping member switches from the loose state to the clamping state, the hook gradually turns and abuts against the upper surface to clamp the bottom of the magazine between the drawer plate and the hook.

[0009] Furthermore, the drawer panel is arranged parallel above the base plate, the roller assembly is located between the base plate and the drawer panel, the drawer panel includes a mounting hole extending from its top to its bottom, the mounting hole corresponds one-to-one with the clamping assembly, the clamping assembly is received in the mounting hole, the pushing end is adapted to extend out of the bottom of the mounting hole for abutting against the roller assembly, and the hook is adapted to extend out of the top of the mounting hole to pass through the clearance hole and abut against the upper surface.

[0010] Furthermore, the mounting base is fixed in the mounting hole and does not protrude relative to the top of the drawer panel. When the clamping member is in the released state, the hook protrudes relative to the top of the drawer panel to allow the clip to be placed behind the drawer panel, and the hook is embedded in the clearance hole.

[0011] Furthermore, the clamping member is Z-shaped in general, and includes a first rod and a second rod. The first rod and the hook extend from both ends of the second rod in a direction away from each other. The pushing end is located at the end of the first rod away from the second rod. The length directions of the first rod, the second rod, and the hook are all perpendicular to the axis of the rotating shaft.

[0012] Furthermore, the clamping member includes a first rod portion and a second rod portion connected at one end to each other, the pushing end is disposed at the other end of the first rod portion, the hook portion is disposed at the other end of the second rod portion, the second magnetic element is fixed to the first rod portion, and the third magnetic element is fixed to the second rod portion; The first magnetic component includes a first magnetic pole near the bottom of the mounting base and a second magnetic pole near the top of the mounting base. When the clamping component is in the clamping state, the first rod abuts against the bottom of the mounting base, and the second magnetic component is in repulsive engagement with the first magnetic pole. When the clamping component is in the loosened state, the second rod abuts against the top of the mounting base, and the third magnetic component is in magnetic attraction engagement with the second magnetic pole.

[0013] Furthermore, the roller assembly includes a roller seat fixed to the base plate and a roller rotatably connected to the roller seat about the Y-axis. When the drawer plate moves from the first position to the second position, the roller is adapted to push against the clamping member.

[0014] Furthermore, the drawer panel is provided with a positioning structure suitable for positioning the magazine in the X and Y axis directions.

[0015] Furthermore, the base frame is provided with at least one base plate at intervals along the Z-axis direction, and each base plate is provided with a corresponding drawer assembly above it. The drawer plate of each drawer assembly is provided with at least one storage area for accommodating the magazine along the Y-axis direction.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the drawer plate moves from the first position to the second position, the roller assembly pushes the clamping member to rotate around the Y-axis. The clamping member passes through the clearance hole at the bottom of the cartridge and directly presses the cartridge against the drawer plate, thereby fixing the cartridge and effectively preventing the cartridge from shifting position when feeding material in the second position. This ensures the continuity and stability of automated feeding, thereby improving the production efficiency and product quality of electronic products. Through the repulsive force design of the first and second magnetic components in the clamping assembly, when the drawer plate returns from the second position to the first position, the roller assembly disengages from the clamping member and the magnetic repulsive force enables the automatic clamping of the cartridge. The reset mechanism eliminates the need for an additional reset drive structure, further simplifying the mechanism and improving operational reliability. Therefore, the drawer plate can simultaneously clamp or release the magazine via linear displacement along the X-axis, eliminating the need for additional cylinders, air circuits, and complex electrical control systems. This fundamentally eliminates the problems of large space occupation and complex control structures associated with traditional cylinder gripper mechanisms due to pneumatic components. It significantly improves the overall compactness of the equipment, making it more adaptable to the miniaturization and integration trends in electronic product manufacturing equipment. It also substantially reduces manufacturing costs, maintenance difficulty, and operational risks caused by air circuit leaks or line faults. Attached Figure Description

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0026] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] Please see Figures 1 to 7As shown, a magazine fixing mechanism corresponding to a preferred embodiment of the present invention includes: a base frame 100 on which a base plate 110 is disposed, and at least one roller assembly 120 is disposed on the base plate 110; a drawer assembly 200 disposed on the base frame 100, which includes a drawer plate 210 for placing a magazine 400, the drawer plate 210 being movable along the X-axis between a first position for picking up and placing the magazine 400 and a second position for fixing the magazine 400; and at least one clamping assembly 300 corresponding to the roller assembly 120, each clamping assembly 300 including a mounting base 310 and a clamping member 320, the mounting base 310 being fixed to the drawer plate 210, and the clamping member 320 being rotatably connected to the mounting base 310 about the Y-axis, the clamping member 320 having... The device has two states: a loose state and a clamped state. The mounting base 310 is provided with a first magnetic element 340, and the clamping element 320 is provided with a second magnetic element 350. The first magnetic element 340 and the second magnetic element 350 repel each other. The bottom of the cartridge 400 is provided with a clearance hole 410 corresponding to the clamping element 320 along the Z-axis. When the drawer plate 210 moves from the first position to the second position, the roller assembly 120 pushes the clamping element 320 to make it rotate to the clamped state. The clamping element 320 presses the cartridge 400 against the drawer plate 210 through the clearance hole 410. When the drawer plate 210 moves from the second position to the first position, the roller assembly 120 disengages from the clamping element 320, and the clamping element 320 rotates back to the loose state of releasing the cartridge 400 under the magnetic repulsion.

[0029] In this invention, when the drawer plate 210 moves from the first position to the second position, the roller assembly 120 pushes the clamping member 320 to rotate around the Y-axis. The clamping member 320 passes through the clearance hole 410 at the bottom of the cartridge 400 and directly presses the cartridge 400 against the drawer plate 210, thus fixing the cartridge 400. This effectively prevents the cartridge 400 from shifting position when feeding material in the second position, ensuring the continuity and stability of automated feeding, thereby improving the production efficiency and product quality of electronic products. Through the repulsive force design of the first magnetic member 340 and the second magnetic member 350 in the clamping assembly 300, when the drawer plate 210 returns from the second position to the first position, the roller assembly 120 disengages from the clamping member 320 and can pass through the magnetic... The repulsive force enables the clamping component 320 to automatically reset without the need for an additional reset drive structure, further simplifying the mechanism and improving operational reliability. Therefore, the drawer plate 210 can simultaneously complete the automatic clamping or releasing of the magazine 400 by linear displacement along the X-axis, eliminating the need for additional cylinders, air circuits, and complex electrical control systems. This fundamentally eliminates the problems of large space occupation and complex control structure caused by pneumatic components in traditional cylinder gripper mechanisms, significantly improving the overall compactness of the equipment structure and making it more adaptable to the trend of miniaturization and integration in electronic product manufacturing equipment. At the same time, it also greatly reduces the manufacturing cost, the difficulty of later maintenance, and the operational risks caused by air circuit leakage and circuit failure.

[0030] Furthermore, the drawer panel 210 is arranged parallel above the base plate 110, and the roller assembly 120 is located between the base plate 110 and the drawer panel 210. The roller assembly 120 includes a roller seat 121 and a roller 122. The roller seat 121 is fixed to the base plate 110, and the roller 122 is rotatably connected to the roller seat 121 around the Y-axis. When the drawer panel 210 moves from the first position to the second position, the roller 122 is adapted to block the clamping member 320, thereby pushing the clamping member 320 and causing the clamping member 320 to turn into a clamping state. With the above structure, there is rolling friction between the roller 122 and the clamping member 320, making the drawer panel 210 push and pull more smoothly, and the clamping member 320 can reliably rotate without being easily damaged.

[0031] Furthermore, the drawer assembly 200 includes a slide rail structure 220 disposed on the base frame 100. The slide rail structure 220 is arranged along the X-axis direction, and the drawer panel 210 is connected to the slide rail structure 220, allowing the drawer panel 210 to slide relative to the base frame 100. A handle 230 is provided on the side of the drawer panel 210 away from the second position, allowing the operator to push the drawer panel 210 to the second position or pull the drawer panel 210 back to the first position by holding the handle 230.

[0032] The drawer panel 210 is provided with a positioning structure, which is suitable for positioning the cartridge 400 in the X and Y axis directions. The positioning structure includes several positioning blocks 240 disposed on the top surface of the drawer panel 210. When the bottom of the cartridge 400 is placed on the top surface of the drawer panel 210, the positioning blocks 240 surround the bottom of the cartridge 400, thereby restricting the position of the cartridge 400 in the X and Y axis directions and ensuring that the clearance hole 410 at the bottom of the cartridge 400 is accurately aligned with the clamping assembly 300.

[0033] Furthermore, the drawer panel 210 includes mounting holes 211 extending from its top to its bottom, each corresponding to a clamping assembly 300, which is received within the mounting hole 211. The clamping assembly 300 includes a pivot 330, and a clamping member 320 is rotatably connected to the mounting base 310 via the pivot 330. One end of the clamping member 320 is a pushing end 3211 for the roller assembly 120 to push against, and the other end has a hook 323. The cartridge 400 has a hollow shell structure with an upper surface 420 and a lower surface 430 at its bottom, and a clearance hole 410 extending from the upper surface 420 to the lower surface 430. When the clamping member 320 switches from a released state to a clamped state, the hook 323 gradually rotates and abuts against the upper surface 420, clamping the bottom of the cartridge 400 between the drawer panel 210 and the hook 323.

[0034] Specifically, a support portion (not shown) protrudes from the inner wall of the mounting hole 211, and the mounting base 310 is supported on and fixedly connected to the support portion. The push end 3211 is adapted to extend out of the bottom of the mounting hole 211 for abutting against the roller assembly 120. The hook portion 323 is adapted to extend out of the top of the mounting hole 211 to pass through the clearance hole 410 and abut against the upper surface 420.

[0035] Preferably, the mounting base 310 does not protrude relative to the top of the drawer panel 210 to avoid obstructing the smooth placement of the bottom of the cartridge 400 on the top of the drawer panel 210. Preferably, when the clamping member 320 is in the released state, the hook 323 protrudes relative to the top of the drawer panel 210, allowing the cartridge 400 to be placed on the drawer panel 210, and the hook 323 to engage with the clearance hole 410. With the above structure, when the drawer panel 210 is in the first position, the hook 323 can position the cartridge 400, ensuring that the cartridge 400 is accurately placed. That is, if the cartridge 400 is not placed in place on the drawer panel 210, the hook 323 and the clearance hole 410 are not aligned, and the hook 323 will abut against the lower surface 430 of the bottom of the cartridge 400, preventing the cartridge 400 from being placed smoothly on the drawer panel 210, thus reminding the operator to reposition it.

[0036] Furthermore, the clamping member 320 includes a first rod portion 321 and a second rod portion 322 connected at one end to each other. The first rod portion 321, the second rod portion 322, and the hook portion 323 are all strip-shaped. The pushing end 3211 is disposed at one end of the first rod portion 321, and the hook portion 323 is disposed at the other end of the second rod portion 322. In this embodiment, the first rod portion 321, the second rod portion 322, and the hook portion 323 are integrally formed to improve their strength and simplify the assembly steps. The clamping member 320 is generally Z-shaped. The first rod portion 321 and the hook portion 323 extend from both ends of the second rod portion 322 in a direction away from each other. The pushing end 3211 is located at the end of the first rod portion 321 away from the second rod portion 322. The length directions of the first rod portion 321, the second rod portion 322, and the hook portion 323 are all perpendicular to the axis of the rotating shaft 330.

[0037] Furthermore, the mounting base 310 has an inward recessed mounting groove 311 on the side opposite to the first position in the Y-axis direction. The mounting groove 311 extends through the bottom and top of the mounting base 310 in the Z-axis direction. The rotating shaft 330 is rotatably mounted on the mounting base 310 and partially housed in the mounting groove 311. The first rod portion 321 is partially embedded in the mounting groove 311 to be fixedly sleeved on the outside of the rotating shaft 330.

[0038] Preferably, the length directions of the first rod 321, the second rod 322, and the hook 323 are perpendicular. When the clamping member 320 is in the released state, the length directions of the first rod 321 and the hook 323 are parallel to the Z-axis, and the length direction of the second rod 322 is parallel to the X-axis. At this time, the pressing surface of the hook 323 is parallel to the Z-axis. When the clamping member 320 is in the clamped state, the length directions of the first rod 321 and the hook 323 are parallel to the X-axis, and the length direction of the second rod 322 is parallel to the Z-axis. At this time, the pressing surface of the hook 323 is perpendicular to the Z-axis and downwards. With the above structure, it can be ensured that the roller 122 reliably pushes the first rod 321 into place, and the hook 323 reliably clamps the magazine 400.

[0039] Furthermore, in a preferred embodiment, the clamping member 320 is also provided with a third magnetic member 360. When the clamping member 320 is rotated to the released state, the third magnetic member 360 and the first magnetic member 340 are magnetically attracted to each other, so that the clamping member 320 can be reliably kept in the released state when no external force is applied, thus preventing the clamping member 320 from shaking during the movement of the drawer plate 210. The first magnetic member 340, the second magnetic member 350 and the third magnetic member 360 are all conventional magnets, which will not be described in detail here.

[0040] Specifically, the second magnetic element 350 is fixed to the first rod portion 321, and the third magnetic element 360 is fixed to the second rod portion 322. The first magnetic element 340 includes a first magnetic pole 341 near the bottom of the mounting base 310 and a second magnetic pole 342 near the top of the mounting base 310. When the clamping member 320 is in the clamped state, the first rod portion 321 abuts against the bottom of the mounting base 310, and the second magnetic element 350 is in a repulsive engagement with the first magnetic pole 341; when the clamping member 320 is in the loosened state, the second rod portion 322 abuts against the top of the mounting base 310, and the third magnetic element 360 is in a magnetic attraction engagement with the second magnetic pole 342. With the above structure, the clamping member 320 can be reliably held in either the loosened or clamped state.

[0041] Specifically, the mounting base 310 has a first fixing hole 312 extending along the Z-axis. A first magnetic element 340 is fixedly embedded in the first fixing hole 312, with the first magnetic pole 341 facing downwards and the second magnetic pole 342 facing upwards. The first magnetic pole 341 and the second magnetic pole 342 do not protrude relative to the bottom and top of the first fixing hole 312. A second fixing hole 3212 is formed by a recess on the side of the first rod portion 321 facing the mounting base 310, and a second magnetic element 350 is fixedly embedded in the second fixing hole 3212. A third fixing hole 3221 is formed by a recess on the side of the second rod portion 322 facing the mounting base 310, and a third magnetic element 360 is fixedly embedded in the third fixing hole 3221.

[0042] Furthermore, the base frame 100 is provided with at least one base plate 110 spaced apart along the Z-axis direction, and a drawer assembly 200 is correspondingly provided above each base plate 110. In this embodiment, two base plates 110 are specifically provided. With the above structure, both the upper and lower drawer assemblies 200 can take out and put in the magazine 400, so as to take out and put in the magazine 400 alternately, so that the second position can always have a magazine 400 for feeding, thereby improving the feeding efficiency.

[0043] Furthermore, each drawer assembly 200 has at least one storage area along the Y-axis on its drawer plate 210 to accommodate different magazines 400, thereby increasing the number of magazines 400 that the fixing mechanism can hold. In this embodiment, each drawer plate 210 has two storage areas to avoid exceeding the operator's fixed operating range due to too many storage areas.

[0044] Preferably, each storage area is provided with four clamping assemblies 300, two of which are located on a straight line parallel to the Y-axis, adjacent to one side of the magazine 400 in the X-axis direction, and the two clamping assemblies 300 are respectively located on both sides of the magazine 400 in the Y-axis direction. The other two clamping assemblies 300 are located on another straight line parallel to the Y-axis, adjacent to the other side of the magazine 400 in the X-axis direction, and the two clamping assemblies 300 are respectively located on both sides of the magazine 400 in the Y-axis direction. With this structure, the number of clamping assemblies 300 can be minimized while ensuring a stable clamping of the magazine 400 at its bottom.

[0045] The working process of the magazine fixing mechanism of the present invention is as follows: Initially, the drawer plate 210 is in the first position, the clamping member 320 is in the loose state, the pushing end 3211 of the first rod 321 extends out of the bottom of the mounting hole 211 of the drawer plate 210, and the hook 323 extends out of the top of the mounting hole 211 of the drawer plate 210; the operator places the magazine 400 on the drawer plate 210, the magazine 400 is positioned by the positioning structure in the X and Y axis directions, and the hook 323 is embedded in the clearance hole 410 at the bottom of the magazine 400; then the operator pushes the magazine 400 to the second position, the first rod 321 is blocked by the roller 122 and gradually rotates clockwise, thereby switching the clamping member 320 to the clamping state. During this process, the first rod 321 gradually rotates into the mounting hole 211, and the hook 323 is in the second rod 322 Driven by the movement, the clip 400 gradually rotates out of the clearance hole 410 and presses against the upper surface 420 of the magazine 400 around the clearance hole 410 to secure the magazine 400. After the magazine 400 finishes feeding, the operator pulls the drawer plate 210 back to the first position. The roller 122 gradually releases its obstruction to the first rod 321. Under the repulsive force of the first magnetic component 340 and the second magnetic component 350, the first rod 321 gradually rotates counterclockwise, causing the clamping component 320 to switch to the loosened state. At the same time, the attraction force of the third magnetic component 360 and the first magnetic component 340 can cooperate with the repulsive force to jointly drive the clamping component 320 to switch to the loosened state. When it is in the loosened state, the third magnetic component 360 and the first magnetic component 340 magnetically engage, allowing the operator to remove the magazine 400 and put the new magazine 400 back into the drawer plate 210.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

2. The magazine fixing mechanism as described in claim 1, characterized in that, The clamping member (320) is provided with a third magnetic element (360). When the clamping member (320) is rotated to the released state, the third magnetic element (360) and the first magnetic element (340) magnetically attract each other.

3. The magazine fixing mechanism as described in claim 2, characterized in that, The clamping member (320) is rotatably connected to the mounting base (310) via a rotating shaft (330). One end of the clamping member (320) is a pushing end (3211) for the roller assembly (120) to push against, and the other end is formed with a hook (323). The bottom of the magazine (400) has an upper surface (420) and a lower surface (430). The clearance hole (410) extends from the upper surface (420) to the lower surface (430). When the clamping member (320) switches from the loose state to the clamping state, the hook (323) gradually turns and abuts against the upper surface (420) to clamp the bottom of the magazine (400) between the drawer plate (210) and the hook (323).

4. The magazine fixing mechanism as described in claim 3, characterized in that, The drawer panel (210) is arranged parallel above the base plate (110). The roller assembly (120) is located between the base plate (110) and the drawer panel (210). The drawer panel (210) includes a mounting hole (211) extending from its top to its bottom. The mounting hole (211) corresponds one-to-one with the clamping assembly (300). The clamping assembly (300) is received in the mounting hole (211). The pushing end (3211) is adapted to extend out of the bottom of the mounting hole (211) for abutting against the roller assembly (120). The hook (323) is adapted to extend out of the top of the mounting hole (211) to pass through the clearance hole (410) and abut against the upper surface (420).

5. The magazine fixing mechanism as described in claim 4, characterized in that, The mounting base (310) is fixed in the mounting hole (211) and does not protrude relative to the top of the drawer plate (210). When the clamping member (320) is in the released state, the hook (323) protrudes relative to the top of the drawer plate (210) to allow the clip (400) to be placed behind the drawer plate (210). The hook (323) is embedded in the clearance hole (410).

6. The magazine fixing mechanism as described in claim 3, characterized in that, The clamping member (320) is generally Z-shaped, and includes a first rod (321) and a second rod (322). The first rod (321) and the hook (323) extend from both ends of the second rod (322) in a direction away from each other. The pushing end (3211) is located at the end of the first rod (321) away from the second rod (322). The length directions of the first rod (321), the second rod (322) and the hook (323) are all perpendicular to the axis of the rotating shaft (330).

7. The magazine fixing mechanism as described in claim 3, characterized in that, The clamping member (320) includes a first rod portion (321) and a second rod portion (322) connected at one end to each other. The pushing end (3211) is disposed at the other end of the first rod portion (321), the hook portion (323) is disposed at the other end of the second rod portion (322), the second magnetic element (350) is fixed to the first rod portion (321), and the third magnetic element (360) is fixed to the second rod portion (322). The first magnetic element (340) includes a first magnetic pole (341) near the bottom of the mounting base (310) and a second magnetic pole (342) near the top of the mounting base (310). When the clamping member (320) is in the clamping state, the first rod (321) abuts against the bottom of the mounting base (310), and the second magnetic element (350) repels the first magnetic pole (341). When the clamping member (320) is in the loosening state, the second rod (322) abuts against the top of the mounting base (310), and the third magnetic element (360) magnetically attracts the second magnetic pole (342).

8. The magazine fixing mechanism as described in claim 1, characterized in that, The roller assembly (120) includes a roller seat (121) fixed to the base plate (110) and a roller (122) rotatably connected to the roller seat (121) about the Y-axis. When the drawer plate (210) moves from the first position to the second position, the roller (122) is adapted to push against the clamping member (320).

9. The magazine fixing mechanism as described in claim 1, characterized in that, The drawer plate (210) is provided with a positioning structure suitable for positioning the magazine (400) in the X-axis and Y-axis directions.
