[0028] The up and down direction in the present invention refers to Figure 1 The up and down direction in the present invention refers to the outer side Figure 3 On the right side of the .

[0029] like Figure 1-3 As shown, the present invention provides a defective product control warehouse, including: a box body 1, a box door 2, and a control center 3, wherein the box body 1 is a frame structure, and rollers 16 and feet 15 are arranged at the bottom of the box body 1. Under the push of external force, the box body 1 moves along the production line through the rollers 16. After moving into place, the feet 15 are raised to fix the box body 1 on the ground; the box door 2 is rotatably connected to the box body 1, and the box door 2 has an open state and a closed state. Generally, the box door 2 is locked on the box body 1 by an electronic lock 13 and is in a normally closed state; the control center 3 is arranged on the upper surface of the top plate of the box body 1, and the control center 3 is composed of a computer 31, a keyboard 32, and a mouse 33. The computer 31 is an all-in-one machine with a display. The control center 3 is also connected to a signal light 34 and a barcode scanner 35. The signal light 34 is a three-color light, and a buzzer 36 is connected to the upper end of the signal light 34.

[0030] like Figure 1-3 As shown, a plurality of partitions 11 are arranged in the box body 1, dividing the space in the box body 1 into a plurality of compartments 12, the compartments 12 are used to place defective printed circuit boards, each compartment 12 is used to place a type of defective printed circuit board, the upper surface of the partition 11 constitutes the bottom surface of the compartment 12, the lower surface of the partition 11 constitutes the top surface of the compartment 12, and the top surface of the uppermost compartment is constituted by the lower surface of the top plate of the box body 1; an electronic lock 13 is arranged on the frame in the box body 1, and is used to lock the box door 2; when the box door 2 is opened, the electronic lock 13 is first unlocked, and then the box door 2 is rotated until the compartment 12 is connected to the outside, as shown in FIG. Figure 1 As shown, at this time, the defective printed circuit board placed in the compartment 12 can be taken out, the door 2 is rotated to the closed state, the electronic lock 13 is locked, and the door 2 is closed. Figure 2As shown, at this time, the defective printed circuit board placed in the compartment 12 cannot be taken out; the box door 2 corresponding to the compartment 12 is provided with an opening 21 for the defective printed circuit board to pass through. When the box door 2 is in a closed state, the defective printed circuit board can be pushed into the compartment 12 through the opening 21. A sensor 14 for detecting the presence or absence of the printed circuit board is provided in the compartment 12. The sensor 14 is electrically connected to the control center 3 and transmits the detection signal to the control center 3; a guide plate 22 extending outward and upward is provided at the outer side of the box door 2 corresponding to the opening 21. When the defective printed circuit board is pushed into the compartment 12 through the opening 21, the guide plate 22 plays a supporting and guiding role. In order to prevent defective printed circuit boards from being stuck in the opening 21 due to tilting, an LED light strip electrically connected to the control center 3 is provided at the upper end of the guide plate 22, and the upper end of the guide plate 22 is higher than the opening 21. After the defective printed circuit board is placed into the compartment 12 through the opening 21 via the guide plate 22, the defective printed circuit board cannot be taken out through the opening 21 due to the obstruction of the upper end of the guide plate 22, thereby preventing the defective printed circuit board placed in the compartment 12 from being taken out at will; the plane where the partition 11 is located is parallel to the plane where the guide plate 22 is located, so that the defective printed circuit board can pass through the guide plate 22 into the compartment 12 and fall on the partition 11 more smoothly.

[0031] Different types of defective printed circuit boards enter different compartments 12. In the actual production process, the proportion of one or several types of defective printed circuit boards may exceed that of other types of defective printed circuit boards. If the size of each compartment 12 is the same, it is easy for one or several compartments 12 to be full, while the number of defective printed circuit boards placed in other compartments 12 is very small. When any compartment 12 is full, the box door 2 needs to be opened to clean the compartment 12. In order to reduce the frequency of opening the box door 2 and reduce the probability of defective printed circuit boards placed in the compartment 12 being taken out at will, the position of the partition 11 inside the box body 1 can be adjusted, that is, the size of each compartment 12 can be adjusted as needed to reduce the frequency of opening the box door 2.

[0032] Different types of defective printed circuit boards are placed in different compartments 12 to prevent them from being mixed. A door 2 that is usually in a closed state is provided, and an opening 21 is provided on the door 2 through which defective printed circuit boards can only be placed into the compartments 12 but not taken out, thereby preventing the defective printed circuit boards placed in the compartments 12 from being taken out at will.

[0033] The specific steps of using the defective product control warehouse provided by the present invention are described below. The steps of use are as follows:

[0034] A. The employee activates the control center 3 with primary authority, uses the barcode scanner 35 to scan the barcode on the defective printed circuit board, and inputs the defective type of the defective printed circuit board into the computer 31 through the keyboard 32 and mouse 33;

[0035] B. The control center 3 controls the corresponding LED light strip 23 to light up according to the type of defective product received, and the employee pushes the printed circuit board into the compartment 12 corresponding to the lit LED light strip 23;

[0036] C. When the sensor 14 in the compartment 12 detects that a printed circuit board has entered the compartment 12, a detection signal is sent to the control center 3, and the control center 3 returns to the state before step A.

[0037] When the detection signal received by the control center 3 in step C. comes from the sensor 14 in other compartments 12, the control center 3 controls the signal light 34 to send out an alarm signal.

[0038] Preferably, when the control center 3 sends out an alarm signal, it is necessary to activate the control center 3 through advanced authority to open the door 2 for processing.

[0039] In the actual production process, employees are prone to misplacing products, and they need to be reminded and checked. In actual operation, the control center 3 controls the corresponding LED light strip to light up according to the type of defective products received, and controls other LED light strips to turn off. Through strong visual contrast, employees are guided to put defective printed circuit boards into the correct compartment to avoid misplacing them. When the light is sufficient, the visual contrast effect produced by the lighting and extinguishing of the white LED light strip is not good. At this time, colored LED light strips can be used for distinction, such as setting the LED light strip to green, or flashing when it is lit, to further enhance the visual contrast and prompt employees to put defective printed circuit boards into the correct compartment.

[0040] In the actual production process, it is not enough to only give employees visual reminders. It is also necessary to check whether the employees have placed the printed circuit boards in the correct compartments. The sensor 14 is used to detect whether any defective printed circuit boards have entered the compartment 12. The sensor 14 is arranged on the upper surface of the partition 11 near the opening 21. When the defective printed circuit boards are placed in the compartment 12, if the detection signal received by the control center 3 comes from the sensor 14 in other compartments 12, the control center 3 controls the signal light 34 to send out an alarm signal; when the signal light 34 sends out an alarm signal, the red light in the three-color light lights up, and the buzzer 36 sounds a buzzer alarm to remind the line leader or team leader to handle it; during processing, the line leader or team leader and other employees with advanced permissions activate the control center 3 through the advanced permissions to open the box door 2 and take out the mixed defective printed circuit boards.

[0041] The above-mentioned implementation modes are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
