When it is necessary to take out the PP board in one of the storage slots 112, the first sensor 135 will remind the staff to take out the PP board from the storage slot 112; when the staff takes out the PP board from the remaining storage slots 112, the first sensor 135 will send a signal to the alarm 137, and the alarm 137 will issue an alarm prompt to prevent the staff from taking the wrong board or missing the board; the weighing sensor 131 will identify the weight of each PP board. When the number of layers of the taken out PP board is greater than or less than the specified number, the weighing system 13 will prompt that the taken out quantity is wrong. At this time, the weighing sensor 131 will send a signal to the alarm 137, and the alarm 137 will issue an alarm prompt to prevent the staff from taking more or less.

[0050] Preferably, the first sensor 135 may be a distance sensor, and when the distance sensor senses that the staff has taken out the PP board from the corresponding storage slot 112, it can be identified as correct.

One first sensor 135 corresponds to a PP board of a storage slot 112. When laminating the PCB, it is necessary to take out the corresponding PP board from one of the storage slots 112. The hot melt machine outputs a signal to the first sensor 135 of the corresponding storage slot 112 through the computer, and the first sensor 135 outputs a signal to the LED light 136. The LED light 136 of the corresponding storage slot 112 lights up, prompting the staff to take out the corresponding PP board from the storage slot 112. When the staff takes out the PP board from the remaining storage slots 112, the first sensor 135 will send a signal to the alarm 137, and the alarm 137 will send an alarm prompt to prevent the staff from taking the wrong board or missing it.

[0059] Different types of core boards are classified and placed on the support plate 213 to reduce the space occupied. Before hot-melting the PCB boards, different core boards are taken out from the support frame 211 and placed on the stacking platform 22. Each time a board is placed, the identification of the core board can be photographed and inspected by the visual inspection camera 226 to prevent wrong taking and ensure the quality of PCB board stacking. The horizontal position or vertical position of the visual inspection camera 226 can also be adjusted according to the size of the core board to facilitate better photographic inspection of the identification of the core board.

[0060] The support frame 211 includes a plurality of longitudinally arranged aluminum profiles 212, and a support plate 213 is transversely installed between the plurality of aluminum profiles 212.

The support plate 213 can adjust its height along the length direction of the aluminum profile 212 through the snap-fitting grooves 214. After loosening the bolts, the height of the support plate 213 can be adjusted so that the distance between two adjacent support plates 213 can be adjusted, and the number of board cores that can be stored can be changed. In addition, the spacing can be shortened to insert more support plates 213 to classify and stack more types of board cores.

[0062] The support frame 211 is also provided with a second sensing system, which includes a second sensor respectively installed on each support plate 213 and an alarm 137 that cooperates with the second sensor for sensing, and the alarm 137 is also connected to the weighing sensor 131 signal; each support plate 213 is equipped with a second sensor, and when it is necessary to take out the core of one of the support plates 213, the second sensor will remind the staff to take out the core from the support plate 213; when the staff takes out the core from the remaining support plates 213, the second sensor will send a signal to the alarm 137, and the alarm 137 will send an alarm prompt to prevent the staff from taking the wrong or missing the core.

[0065] Preferably, in addition, the second sensing system also includes an LED light 136 connected to the second sensor signal. The second sensor, LED light 136 and alarm 137 are all existing hardware systems. Engineers program the second sensor, LED light 136 and alarm 137 accordingly. One second sensor corresponds to a core of a support plate 213. When laminating the PCB, it is necessary to take out the core of the corresponding model from one of the support plates 213. The hot melt machine outputs a signal to the second sensor of the corresponding support plate 213 through the computer, and outputs a signal to the LED light 136 through the second sensor. The LED light 136 of the corresponding support plate 213 lights up, prompting the staff to take out the core of the corresponding model from the support plate 213. When the staff takes out the core from the remaining support plates 213, the second sensor will send a signal to the alarm 137, and the alarm 137 will send an alarm prompt to prevent the staff from taking the wrong or missing the core.

The control panel and the computer can be wirelessly connected via a wifi protocol, a bluetooth protocol or a WLAN protocol. When it is necessary to take out one of the models of PP boards, the computer sends a signal to the control panel, which is connected to the first sensor 135 of the corresponding storage slot 112. After the first sensor 135 receives the signal, the model of the PP board to be taken and the quantity taken are displayed on the display screen 133; the staff is reminded to take the corresponding model of PP board from the corresponding storage slot 112 to the stacking platform 22. At this time, the first sensor 135 senses that the staff has taken the board correctly, and the signal of the first sensor 135 matches the signal sent by the computer, and the green light for passing is turned on.

[0072] If the staff takes out the PP board from the remaining storage slots 112, the signal instruction of the first sensor 135 corresponding to the storage slot 112 does not match the trigger signal of the computer, and the first alarm 137 issues an alarm prompting wrong taking.

[0073] When the staff takes out two first PP boards from the remaining storage slots 112, the stacking platform 22 triggers a signal to the corresponding weighing sensor 131 through the computer. When the staff takes out more than two first PP boards from the corresponding storage slots 112, the corresponding weighing sensor 131 recognizes that the weight of the stacked first PP boards decreases and deviates from the set value. The weighing sensor 131 will send a signal to the first alarm 137, issuing an alarm prompt for taking too much, taking too little or missing something.
