[0032] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] The nail feeder of the present utility model is described below with reference to the accompanying drawings.

[0034] The utility model provides a nail feeding device, such as Figure 1 and Figure 2 As shown, the nail feeder includes:

[0035] The box body 1 is provided with a switch door 11 and a door lock 12 for locking the switch door 11, and the door lock 12 is controlled by a driving assembly 13;

[0036] A memory, used to store model information of screws added into the box 1;

[0037] A scanner for scanning the model information on the packaging bag of the screws to be added; and

[0038] The controller is used to compare the model information stored in the memory with the model information obtained by scanning the scanner, and control the drive component 13 to operate to unlock the switch door 11 when the comparison results are consistent.

[0039] The switch door 11 is normally in a locked state, and the memory stores the model information of the screws previously added to the box body 1. When the nail feeder needs to add materials, the operator needs to use a scanner to scan the model information on the packaging bag of the screws to be added. Only when the model information on the screw packaging bag is consistent with the model information stored in the memory, the door lock 12 will be unlocked, and the operator can open the switch door 11 to add screws to the box body 1. In summary, the nail feeder in the utility model can reduce the probability of mistakenly adding screws and improve the accuracy of screw addition by adding an operation of scanning the code to open the door in the step of adding materials.

[0040] like Figure 1 As shown, in an embodiment of the utility model, the box body 1 may be provided with a matching hole for locking with the door lock 12, the driving assembly 13 includes a telescopic driving member for driving the door lock 12 to enter and exit the matching hole, and the controller is used to control the telescopic driving member to move when the comparison result is consistent, so as to drive the door lock 12 to extend from the matching hole. Specifically, the door lock 12 may be a shaft or a rod connected to the telescopic shaft of the telescopic driving member, or the door lock 12 may directly be a part of the telescopic shaft of the telescopic driving member, and the locking and opening of the switch door 11 can be achieved by controlling the telescopic driving member to drive the door lock 12 to extend into and out of the matching hole.

[0041] In the embodiment of the utility model, a matching groove may be further provided on the box body 1 to lock and cooperate with the door lock member 12 .

[0042] like Figure 3 As shown, in an embodiment of the utility model, the telescopic driving member can be a driving cylinder 131, and the driving component 13 also includes an electromagnetic control valve 132 for controlling the telescopic direction of the driving cylinder 131. The electromagnetic control valve 132 has a first valve position for guiding high-pressure gas to the rod chamber of the driving cylinder 131 and a first electromagnetic control end for controlling the electromagnetic control valve 132 to switch to the first valve position. The first electromagnetic control end is controlled by a first relay 133, and the controller is also used to control the on and off of the first relay 133.

[0043] Specifically, when the model information on the screw packaging bag is consistent with the model information stored in the memory, the controller will generate a pulse signal and send it to the first relay 133. After receiving the signal, the first relay 133 will switch to the on state. At this time, the first electromagnetic control end is energized and works. The electromagnetic control valve 132 switches to the first valve position under the action of the electromagnet, driving the rod chamber of the cylinder 131 to intake air and the rodless chamber to exhaust air, driving the cylinder 131 to retract, and unlocking the switch door 11.

[0044] In the embodiment of the utility model, the telescopic driving member can also be an electric cylinder, an oil cylinder or other components.

[0045] like Figure 3 As shown, in the embodiment of the utility model, the electromagnetic control valve 132 also has a middle stop valve position, and the electromagnetic control valve 132 is in the middle stop valve position when the power is off, and the first relay 133 is a normally open contact relay with a delayed disconnection function. By setting a normally open contact relay with a delayed disconnection function, the driving cylinder 131 can be automatically controlled to switch to a pressure-maintaining state after the cylinder retracts to the position, thereby avoiding the driving cylinder 131 from working for a long time and affecting the service life.

[0046] It should be noted that the pressure-maintaining state of the cylinder refers to the cylinder being disconnected from the air source.

[0047] like Figure 3 and Figure 4 As shown, in an embodiment of the utility model, the electromagnetic control valve 132 also has a second valve position for directing high-pressure gas to the rodless chamber of the driving cylinder 131 and a second electromagnetic control end for controlling the electromagnetic control valve 132 to switch to the second valve position. The second valve position is used to control the extension of the driving cylinder 131. The second electromagnetic control end is controlled by the second relay 134. A touch component 2 is also provided between the box body 1 and the switch door 11. The touch component 2 is used to trigger a closing signal when the switch door 11 is in a closed state to connect the second relay 134.

[0048] like Figure 3 As shown, in the embodiment of the present utility model, the second relay 134 is a normally open contact relay with a delayed disconnection function.

[0049] Specifically, Figure 1 and Figure 4As shown, the touch assembly 2 includes a touch seat 21 arranged on the inner side wall of the box body 1 and a trigger 22 arranged on the switch door 11 and used to cooperate with the touch sheet 215 on the touch seat 21. The touch seat 21 is provided with a V-shaped groove 211, and an avoidance channel 212 is provided on one of the inclined surfaces of the V-shaped groove 211. The avoidance channel 212 is provided with a movable metal ball 213 and an elastic pushing member 214 for pushing toward the other inclined surface of the V-shaped groove 211. The touch sheet 215 is arranged on the V-shaped groove 211. The groove 211 is arranged on the inclined surface away from the avoidance channel 212 and aligned with the avoidance channel 212. When the switch door 11 is open, the elastic push member 214 will push the movable metal ball 213 to make the movable metal ball 213 contact with the touch sheet 215. When the switch door 11 is closed, the trigger member 22 on the switch door 11 will first contact with the movable metal ball 213. At this time, a conduction circuit is formed between the trigger member 22, the movable metal ball 213, and the touch sheet 215 to generate a closing signal. When the second relay 134 receives the closing signal, it will be turned on to energize the second electromagnetic control terminal. At this time, the driving cylinder 131 will switch to the second valve position, and the driving cylinder 131 will perform an extension action, so that the switch door 11 is automatically locked. When the switch door 11 is in the process of closing, the movable metal ball 213 will be pushed toward the avoidance channel 212 by the trigger member 22. At this time, the movable metal ball 213 will lose contact with the touch-sensitive sheet 215. Through the above-mentioned setting, it can be ensured that the closing signal is a pulse signal. By setting the closing signal to a pulse signal and setting the second relay 134 to a normally open contact relay with a delayed disconnection function, the driving cylinder 131 can be automatically controlled to switch to the pressure-maintaining state after the cylinder is extended into place, thereby avoiding the driving cylinder 131 working for a long time and affecting its service life.

[0050] It should be noted that when the switch door is completely closed, the trigger member 22 and the touch-sensitive sheet 215 are in a spaced state.

[0051] In an embodiment of the utility model, the nail feeder further comprises an alarm, which is electrically connected to the controller. When the model information stored in the memory is inconsistent with the model information obtained by scanning with the scanner, the alarm will be triggered to remind the operator that the model of the current screw is wrong and needs to be corrected.

[0052] In an embodiment of the utility model, the nail feeder further comprises a data entry unit, which is communicatively connected to the memory and can enter data into the memory, thereby realizing the change of the model information of the screws stored in the memory.

[0053] In an embodiment of the present utility model, the scanning gun is a barcode scanning gun, and the model information is QR code information.

[0054] In summary, the nail feeder in the utility model can improve the accuracy and efficiency of screw adding by adding a code scanning error prevention step during the material adding process, and can also issue an alarm when the screw model is wrong to remind the operator to correct it. Furthermore, by establishing QR code information of the screws, the management of the screws can be facilitated.
