[0010] As an option, the picking boxes can be stacked on a shelf.

[0011] A method for controlling a screw feeding mechanism comprises the following steps:

[0012] S1. When picking up materials, the card reader reads the information in the identification card. After the control mechanism confirms that the information is correct, the first barcode scanner obtains the picking information on the picking list. The picking information includes the screw model and quantity. The control mechanism drives the corresponding feeder to move the internal screws out of the discharge port according to the quantity on the picking list and drop them into the picking box below. When the pressure sensor detects that a screw has fallen into the picking box, the control mechanism drives the corresponding first indicator light to be always on, and the picking personnel takes out the picking box with screws inside. When the pressure sensor detects that the picking box is taken out, the control mechanism drives the corresponding first indicator light to flash, and the picking personnel returns the picking box to its place. When the pressure sensor detects that the picking box is put back, the first indicator light goes out.

[0013] S2. When refilling, the card reader reads the information in the identification card. After the control mechanism confirms that the information is correct, the second barcode scanner obtains the refilling information on the refilling list, which includes the screw model and quantity. The control mechanism turns off the electromagnet on the corresponding feeder to open the lid and drives the second indicator light corresponding to the feeder to be constantly on. After the refilling personnel pours the screws into the hopper, they press the confirmation button corresponding to the feeder. The control mechanism starts the electromagnet to close the lid of the feeder that has completed refilling, and the second indicator light goes out.

[0014] S3. When refilling a material box, the card reader reads the information in the identification card. After the control mechanism confirms that the information is correct, the pressure sensor inputs the position where the material box is not detected into the control mechanism. The control mechanism drives the first indicator light at the corresponding position to flash. After the refilling personnel places the material box at the corresponding position, the pressure sensor detects the material box and the first indicator light goes out.

[0015] The beneficial technical effect of the present invention is as follows: the screw feeding mechanism includes: a box, a feeder, a material collection box, a card reader, a first barcode scanner, a second barcode scanner and a control mechanism. When in use, the user's identity is identified by the card reader, and then the information on the material collection list is identified by the first barcode scanner. The control mechanism controls the feeder to automatically discharge the material for the material collection personnel to pick up the material, thereby avoiding the situation where the wrong material is picked up due to manual material selection. The first indicator light reminds the material collection personnel of the material collection position. At the same time, due to the provision of a pressure sensor, it is possible to detect whether the feeder is discharging the material normally and whether the material collection box is returned to its position. In addition, when replenishing the material, the second barcode scanner obtains the information on the replenishment list. The feeder's hopper is automatically opened by the electromagnet, and the second indicator light reminds the replenishment personnel of the replenishment position, thereby avoiding the situation where the wrong material is placed. The confirmation button is pressed to drive the electromagnet to close the hopper. Not only is it not easy to pick up the wrong screw, but the degree of automation of material collection and replenishment is also higher. It has the advantages of not being easy to pick up the wrong screw and a high degree of automation. The screw feeding mechanism control method not only prevents screws from being picked up incorrectly, but also increases the degree of automation in both picking and refilling. The method has the advantages of preventing screws from being picked up incorrectly and achieving a high degree of automation.

[0030] like Figure 1-Figure 3 As shown, the present application also discloses a screw feeding mechanism control method, which is characterized by comprising the following steps:

[0031] S1. When picking up materials, the card reader 4 reads the information in the identification card. After the control mechanism confirms that the information is correct, the first barcode scanner 5 obtains the picking information on the picking list. The picking information includes the screw model and quantity. The control mechanism drives the corresponding feeder 2 to move the internal screws out of the discharge port according to the quantity on the picking list and drop them into the picking box 3 below. When the pressure sensor detects that a screw has fallen into the picking box 3, the control mechanism drives the corresponding first indicator light 7 to be always on, and the material picking personnel takes out the picking box 3 with screws inside. When the pressure sensor detects that the picking box 3 is taken out, the control mechanism drives the corresponding first indicator light 7 to flash, and the material picking personnel returns the picking box 3 to its place. When the pressure sensor detects that the picking box 3 is put back, the first indicator light 7 goes out.

[0032] S2. When refilling, the card reader 4 reads the information in the identification card. After the control mechanism confirms that the information is correct, the second barcode scanner 6 obtains the refilling information on the refilling list, which includes the screw model and quantity. The control mechanism turns off the electromagnet on the corresponding feeder 2 so that the lid can be opened and drives the second indicator light 8 corresponding to the feeder 2 to be always on. After the refilling personnel pours the screws into the hopper, they press the confirmation button 9 corresponding to the feeder 2. The control mechanism starts the electromagnet so that the lid of the feeder 2 that has completed the refilling is closed, and the second indicator light 8 goes out.

[0033] S3, when retrieving the material box 3, the card reader 4 reads the information in the identification card. After the control mechanism confirms that the information is correct, the pressure sensor inputs the position of the material box 3 that has not been detected into the control mechanism. The control mechanism drives the first indicator light 7 at the corresponding position to flash. After the retrieving personnel places the material box 3 at the corresponding position, the pressure sensor detects the material box 3 and the first indicator light 7 goes out. Since the feeder 2 automatically discharges the material according to the information on the material retrieving list and assists in positioning through the first indicator light 7 during the material retrieving process, and the corresponding material bin is opened by the electromagnet according to the information on the material retrieving list during the material retrieving process, and the second indicator light 8 assists in positioning, it is not only difficult to take the wrong screw, but also the degree of automation of material retrieving and retrieving is higher. It has the advantages of being difficult to take the wrong screw and having a high degree of automation.

[0034] The screw feeding mechanism control method of this embodiment has the advantages of being difficult to misplace screws and having a high degree of automation.
