Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent storage technology for tools and equipment, and in particular to a movable stencil light-activated storage cabinet for the SMT industry. Background Technology
[0002] Stencils are essential tools in the solder paste printing process of circuit board manufacturing. Traditional stencils have thick borders that cannot be reused. Therefore, movable stencils with separate mesh and borders and their matching frames have emerged. The frames can be reused, and the movable stencils are thinner, enabling higher-density storage and saving storage space. However, when storing movable stencils at high density, their similar appearance and thin borders make them unsuitable for attaching visual labels. This leads to time-consuming and laborious manual searching for the target movable stencil, and can result in discrepancies between the actual storage location and the manually registered location, further leading to the wrong model of movable stencil being retrieved. Summary of the Invention
[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides an SMT industry movable stencil lighting induction storage cabinet that provides an independent storage space for each movable stencil, an independent LED storage space light at the front end of each storage space, an independent induction switch and Hall sensor at the rear end of each storage space, and the induction switches and Hall sensors of adjacent storage spaces are staggered in height.
[0004] To achieve the above objectives, the present invention provides the following technical solution: A mobile stencil lighting sensor storage cabinet for the SMT industry includes a cabinet frame, LED light strips, storage slots, a sensor component, a sensor switch, and sheet metal for fixing the storage slots. The LED light strips are fixed to the front of the crossbeam of the cabinet frame. The storage slots are installed on the top and bottom of the cabinet frame via the sheet metal for fixing the storage slots. The sensor component is installed on the back column of the cabinet frame via screws. The sensor component has a rotating base for the switch, and the rotating base has a rotating hole for the switch. The sensor switch is engaged in the rotating hole for the switch.
[0005] Preferably, the LED light strip has a plurality of LED lights distributed on it, and the storage slot has a plurality of slots. Each light on the LED light strip corresponds to one slot in the storage slot, and each slot in the storage slot can store a movable steel mesh.
[0006] Preferably, the storage slot has several flat cavities, and the storage slot fixing sheet metal has several serrated protrusions. The serrated protrusions are inserted into the flat cavities to fix the storage slot to the cabinet frame.
[0007] Preferably, the inductive stop is equipped with an inductive magnet, and the inductive assembly is equipped with a Hall sensor. When the movable steel mesh is pushed in along the storage slot, the inductive stop rotates clockwise along the stop rotation hole, and the inductive magnet moves away from the Hall sensor. When the movable steel mesh is moved out along the storage slot, the inductive stop rotates counterclockwise along the stop rotation hole, and the inductive magnet moves closer to the Hall sensor. When the inductive magnet moves closer to and away from the Hall sensor, the Hall sensor determines the storage and retrieval of the movable steel mesh by monitoring the change in magnetic field strength.
[0008] Preferably, the back of the cabinet frame is equipped with two parallel sensing components, and the sensing levers installed on the upper sensing component and the sensing levers installed on the lower sensing component are misaligned in the vertical direction. That is, two adjacent slots on the storage slot correspond to one sensing lever installed on the upper sensing component and another sensing lever installed on the lower sensing component, respectively.
[0009] Preferably, the LED light strip is fixed to the front of the front beam of the cabinet frame by the first screw, and the storage slot fixing sheet metal is fixed to the cabinet frame by the second screw.
[0010] Compared with the prior art, the beneficial effects of the present invention are: 1. The sensor switches corresponding to adjacent slots are designed to be staggered vertically to avoid mutual interference between the sensor switches corresponding to adjacent slots during rotation. 2. The storage slots are fixed to the cabinet frame by sheet metal, and no additional screws are required for fixing. 3. By using a Hall sensor to detect the change in the magnetic field strength of the magnet during the rotation of the induction switch, the access action of the movable steel mesh is monitored. The induction magnet and the Hall sensor do not need to be in contact, so there is no contact oxidation problem. When the movable steel mesh is removed, the induction switch automatically resets without the need for a spring, so there is no spring fatigue failure problem. The Hall sensor is not affected by ambient light or dust accumulation, so it can be used in natural light and in environments with low cleanliness. 4. Each slot has an individual LED indicator light to help operators quickly locate the target moving steel mesh; 5. The sensing components and sensing switches are installed on the back. The removal of the movable steel mesh can be detected immediately, and an immediate reminder can be given if the wrong movable steel mesh is removed. Furthermore, the residual liquid after cleaning the movable steel mesh will not flow onto the sensing components and cause malfunctions. Attached Figure Description

[0013] like Figure 1 , 2As shown in Figures 3, 4, 5, and 6, an SMT industry movable stencil lighting sensor storage cabinet includes a cabinet frame 1, LED light strips 2, storage slots 3, sensing components 4, sensing levers 5, and storage slot fixing sheet metal 6. The LED light strips 2 are fixed to the front of the front crossbeam of the cabinet frame 1. The storage slots 3 are installed on the top and bottom of the cabinet frame 1 via the storage slot fixing sheet metal 6. The sensing components 4 are installed on the rear column of the cabinet frame 1 via screws 7. The sensing components 4 are provided with a lever rotating base 11, and the lever rotating base 11 is provided with a lever rotating hole 12. The sensing lever 5 is inserted into the lever rotating hole 12. The LED light strips 2 have a plurality of LEDs distributed on them. The storage slots 3 have a plurality of slots, with each LED of the LED strip 2 corresponding to one slot in the storage slot 3. Each slot in the storage slot 3 can store one movable stencil 13. The storage slot 3 has several flat cavities 15, and the storage slot fixing sheet metal 6 has several serrated protrusions 14. The serrated protrusions 14 are inserted into the flat cavities 15 to fix the storage slot 3 to the cabinet frame 1. The induction stop 5 is equipped with an induction magnet 9, and the induction component 4 is equipped with a Hall sensor 10. When the movable steel mesh 13 is pushed into the storage slot 3, the induction stop 5 rotates clockwise along the stop rotation hole 12, and the induction magnet 9 moves away from the Hall sensor 10. When the movable steel mesh 13 is moved out of the storage slot 3, the induction stop 5 rotates counterclockwise along the stop rotation hole 12, and the induction magnet 9 moves closer to the Hall sensor 10. When the induction magnet 9 moves closer to and away from the Hall sensor 10, the Hall sensor 10 determines the storage and retrieval of the movable steel mesh 13 by monitoring the change in magnetic field strength. The back of the cabinet frame 1 is equipped with two parallel layers of sensing components 4. The sensing stops 5 installed on the upper layer of the sensing components 4 are vertically misaligned with the sensing stops 5 installed on the lower layer of the sensing components 4. That is, two adjacent slots on the storage slot 3 correspond to one sensing stop 5 installed on the upper layer of the sensing components 4 and another sensing stop 5 installed on the lower layer of the sensing components 4, respectively. The LED light strip 2 is fixed to the front of the crossbeam of the cabinet frame 1 by screw 7, and the storage slot fixing sheet metal 6 is fixed to the cabinet frame 1 by screw 8.
[0014] The sensing magnet 9 and the Hall sensor 10 of the present invention are non-contact sensing, which eliminates the problems of contact oxidation and dust interference, and can work normally under natural light. The reset of the sensing switch 5 does not require the aid of a spring, thus eliminating the problem of spring fatigue.
[0015] The vertical misalignment design of the sensing stop 5 installed on the upper layer of the sensing component 4 on the back of the cabinet frame 1 of the present invention and the sensing stop 5 installed on the lower layer of the sensing component 4 can effectively avoid the interference problem of the sensing stop 5 in adjacent slots during rotation, and the residual liquid after cleaning of the movable steel mesh 13 will not remain on the sensing component 4.
[0016] The storage slot 3 of the present invention is installed on the cabinet frame 1 by fixing sheet metal 6 through the storage slot, and the storage slot 3 does not require additional screws for fixing.
[0017] When the operator places the movable steel mesh 13 into any empty slot of the storage slot 3, the sensing component 4 automatically monitors the rotation of the sensing lever 5 and records the actual slot information of the movable steel mesh 13, replacing manual recording of the slot and improving work efficiency and accuracy.
[0018] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
