[0030] like Figure 1 and Figure 2As shown, this embodiment provides a door lock system that can lock the door panel of a protective door to the door frame. The system includes an electromagnet 1, a magnetic plate 2, a mounting plate 7, and a control unit 3. One of the mounting plate 7 and the magnetic plate 2 is located on the door frame, and the other is located on the door panel. During the production of the door panel or door frame, the mounting plate 7 can be directly installed on the door panel or door frame. The mounting plate 7 has a mounting cavity, providing installation space for the electromagnet 1. Simultaneously, the mounting plate 7 also protects the electromagnet 1. The electromagnet 1 is located in the mounting cavity and faces the magnetic plate 2. The mounting plate 7 fixes the electromagnet 1 to the door panel or door frame. When installing or replacing the electromagnet 1, no secondary processing of the door panel or door frame is required, thus ensuring that the installation and disassembly process does not damage the door panel or door frame and guarantees the strength of the door panel or door frame. When electromagnet 1 is electrically connected to the power source, it can attract and lock the magnetic plate 2. When electromagnet 1 is powered on, it can attract and lock the magnetic plate 2, thus fixing electromagnet 1 and magnetic plate 2, thereby fixing the door frame and door panel, locking the protective door, preventing the protective door from shaking and triggering an alarm, causing equipment shutdown, reducing the failure rate of the production line, and improving production efficiency.

[0031] The control unit 3 includes a switch 31, which is electrically connected to an electromagnet 1. The switch 31 has a locked state and an unlocked state. In the locked state, the electromagnet 1 is connected to the power supply; in the unlocked state, the electromagnet 1 is disconnected from the power supply. During production, the switch 31 is in the locked state. In this state, the electromagnet 1 is connected to the power supply and attracts the locking magnet 2, thus locking the protective door. Rotating the switch 31 to the unlocked state disconnects the electromagnet 1 from the power supply, releasing the lock on the protective door. This allows the operator to easily open the door during production to inspect the equipment.

[0032] Specifically, mounting plate 7 is disposed on the door frame, and magnet plate 2 is disposed on the door panel. Magnet plate 2 has a first through hole, and the door panel has a first threaded hole. A first screw passes through the first through hole and is threaded into the threaded hole. Mounting plate 7 has an L-shaped structure, forming a mounting cavity. The size of the mounting cavity can be adapted to the electromagnet 1, so that the two adjacent sides of the electromagnet 1 fit precisely against the two sides of mounting plate 7.

[0033] Optionally, the electromagnet 1 and the mounting plate 7 are detachably connected, facilitating the installation, removal, and replacement of the electromagnet 1. Specifically, the electromagnet 1 has two second through holes 71 spaced apart, and the mounting plate 7 has two second threaded holes.

[0037] Specifically, circuit board 32 is mounted on the door frame. Switch 31 is an automatic reset switch. During production, switch 31 is in the unlocked state, circuit board 32 is de-energized and delayed for a period of time. At this time, electromagnet 1 is disconnected from the power supply, the door panel and door frame are not locked, and the protective door can be opened. After a period of time, switch 31 automatically resets and enters the locked state. Circuit board 32 is energized again, electromagnet 1 is connected to the power supply, and when the magnetic plate 2 approaches electromagnet 1, it is attracted to it, locking the door panel and door frame. By setting circuit board 32, the door can be opened or closed quickly. Switch 31 can be a rotary switch or a push-button switch. In other embodiments, switch 31 can also be a manual reset switch. During production, manually opening switch 31 disconnects electromagnet 1 from the power supply, and electromagnet 1 is not energized; manually closing switch 31 connects electromagnet 1 to the power supply, and electromagnet 1 is energized.

[0038] Optionally, the door lock system also includes a latch 5, which is connected to the door panel or door frame. The electromagnet 1 is connected to the circuit board 32 via a cable 4, and the circuit board 32 is connected to the power supply via a cable 4. The cable 4 is latched to the latch 5 to fix the cable 4 to the door panel or door frame, preventing the cable 4 from becoming tangled and making the door lock system neat and aesthetically pleasing.

[0039] Specifically, the buckle 5 has a plate-like structure with a groove protruding outward in the middle, through which the cable 4 passes. Both ends of the buckle 5 have a fourth through hole, and the door frame has two third threaded holes. A third screw passes through the fourth through hole and is threaded into the third threaded hole to fix the buckle 5 to the door frame. In other embodiments, the buckle 5 can also be fixed to the door frame by snap-fitting or adhesive bonding.

[0040] Optionally, the door lock system also includes a protective box 6, which is connected to the door panel or door frame. The circuit board 32 is installed inside the protective box 6 to protect the circuit board 32 and prevent external objects from damaging the circuit board 32.

[0041] Furthermore, the protective box 6 includes a box body 61 and a box cover 62. The box body 61 is connected to a door panel or door frame, and the circuit board 32 is installed inside the box body 61. The box cover 62 is detachably connected to the box body 61 to facilitate the inspection and maintenance of the circuit board 32. The box cover 62 is provided with mounting holes, and the switch 31 passes through the mounting holes and is electrically connected to the circuit board 32 to fix the switch 31.

[0042] Specifically, the box body 61 has a cubic structure with an opening on one side. The box body 61 is connected to a door frame. The side of the box body 61 opposite the opening can be installed on the door frame by means of snap-fit, adhesive, fastener connection, or welding; this embodiment does not limit this method. The box cover 62 is plate-shaped. The box cover 62 is installed at the opening of the box body 61. The box cover 62 can be snap-fitted to the box body 61 or connected to the box body 61 via a connector; this embodiment does not limit this method.

[0043] Optionally, the door lock system also includes an indicator light 8, which is electrically connected to the electromagnet 1. In the locked state, the indicator light 8 is lit, and in the unlocked state, the indicator light 8 is turned off. The working status of the electromagnet 1 can be displayed through the indicator light 8.

[0044] Specifically, the indicator light 8 is installed on the top of the housing 61. The indicator light 8 can be connected to the housing 61 by means of snap-fit ​​or adhesive, and the indicator light 8 is connected to the circuit board 32 by wires.

[0045] Optionally, the door lock system also includes a control module 9, which is connected in series with the electromagnet 1, the switch 31 and the power supply. The control module 9 can control the electromagnet 1 to be turned on or off with the power supply.

[0046] Specifically, control module 9 is a D0 module (Digital Output module) connected in series between switch 31 and the power supply. The door lock system has working and non-working states. When the door lock system is in the working state, the D0 module outputs voltage, switch 31 is in the locked state, electromagnet 1 is connected to the power supply and energized, switch 31 is in the unlocked state, and electromagnet 1 is disconnected from the power supply. When the door lock system is in the non-working state, the D0 module does not output voltage, and electromagnet 1 is never energized, that is, the door lock system does not work.

[0047] This embodiment also provides an unpacking station, which includes a housing, an unpacking mechanism, and the aforementioned door lock system. The unpacking mechanism is disposed inside the housing. The housing includes a door frame and a door panel. The door panel is connected to the door frame. One of the mounting plate 7 and the magnetic plate 2 is connected to the door frame, and the other is connected to the door panel, which enables the unpacking station to be opened or closed quickly, preventing the door panel from shaking when the unpacking station is working.
