Description
Technical Field
[0001] This utility model relates to the field of nail feeding equipment technology, and in particular to an air-blowing screw feeder. Background Technology
[0002] In existing documents, Chinese utility model publication number CN217555102U proposes an automatic screw feeding device for battery PACK processing. By setting up a material box, a feeding tray, a feeding mechanism and a control component, screws can be stored in the material box and discharged sequentially through the feeding tray, feeding mechanism and control component. It can be directly connected to the processing equipment for material supply. The design of the control component is proposed: the control component includes a connecting seat, a movable block, and a cylinder. A docking groove is provided on the outer side of the connecting seat. The end of the feeding mechanism away from the material box extends into the docking groove, so that the screw fed by the feeding mechanism can be accurately inserted. The movable block is slidably set inside the connecting seat and has a discharge port on the outside. When the discharge port is aligned with the docking groove, the fed screw can directly enter the discharge port and be discharged to the outside. When the discharge port is not aligned with the docking groove, the movable block will block the feeding mechanism from continuing to feed. The cylinder is fixed on the connecting seat, and the telescopic end is fixed to the movable block. The cylinder pushes the movable block to perform the action, thereby completing the screw discharge control. It should be noted that the connecting seat has an opening corresponding to the discharge port for the screw to be discharged downwards.
[0003] Screws discharged downwards from the outlet fall into the screw conveying pipe. Thereafter, under the pressure of the airflow from the blowing system, the screws are blown into the screw conveying pipe to the nailing position, such as the bit of an automatic screw fastening machine. This screw feeding method is also called blow-feeding. The screw blowing structure used is, for example, "A novel screw blowing structure" disclosed in Chinese Utility Model No. CN217478510U.
[0004] However, in the aforementioned CN217555102U document, during the process of the screw moving into the control component and discharging downwards, only one screw can be fed in a single extension and retraction of the cylinder. A similar structural design is disclosed in Chinese Utility Model No. CN213196429U, "An escapement mechanism for screw feeding," where only one screw can be fed in a single extension and retraction of the cylinder, which is not conducive to rapid feeding and needs improvement.

[0062] In some embodiments, the top of the support member 6 is provided with a first guide rail 603 that cooperates with the first moving member 8, and a second guide rail 604 that cooperates with the second moving member 9.
[0063] The first moving part 8 is slidably mounted on the first guide rail 603, and the second moving part 9 is slidably mounted on the second guide rail 604.
[0064] In this embodiment, the rear end of the first moving member 8 has a first receiving bracket 801 that cooperates with the outlet 201 of the guide rail, and the first receiving bracket 801 has a first receiving translation port 802 for receiving screws.
[0065] The rear end of the second moving part 9 has a second receiving bracket 901 that mates with the outlet 201 of the guide rail. The second receiving bracket 901 has a second receiving translation port 902 for receiving screws.

[0067] Specifically, the head of the screw may be supported by a corresponding receiving bracket.
[0068] For example, the receiving brackets (first receiving bracket 801 and second receiving bracket 901) are forked in shape. The receiving brackets have upper and lower through channels corresponding to the forks, and a rear side fork (i.e., the corresponding receiving translation port) that connects the upper and lower through channels and corresponds to the outlet of the guide rail.
[0069] The screw shank moves from the rear to the fork into the vertical through-channel, and the screw head is positioned above the receiving bracket and moves to be supported by the two forks of the receiving bracket.
[0070] Driven by the left and right movement of the support member 6, the first receiving bracket 801 of the first moving member and the second receiving bracket 901 of the second moving member can alternately switch to align with the outlet 201 of the guide rail, so as to take turns receiving the screws that are arranged forward from the outlet 201 of the guide rail.
[0071] In this embodiment, the mounting base 3 is provided with a first positioning component 10 that cooperates with the first moving component 8 and a second positioning component 11 that cooperates with the second moving component 9.
[0072] When the support member 6 moves to the left, the first positioning assembly 10 is configured to drive the first moving member 8 forward or to drive the first moving member 8 to slide forward on the first guide rail 603, and the second positioning assembly 11 is configured to drive the second moving member 9 backward or to drive the second moving member 9 to slide backward on the second guide rail 604, so that the first receiving bracket 801 can be driven (to the left and forward) to the outlet 201 away from the guide rail, so that the second receiving bracket 901 can be driven (to the left and backward) to be aligned with the outlet 201 of the guide rail.
[0073] When the support member 6 moves to the right, the first positioning assembly 10 is configured to drive the first moving member 8 to move backward or to drive the first moving member 8 to slide backward on the first guide rail 603, and the second positioning assembly 11 is configured to drive the second moving member 9 to move forward or to drive the second moving member 9 to slide forward on the second guide rail 604, so that the first receiving bracket 801 can be driven (to the right and backward) to align with the outlet 201 of the guide rail, and the second receiving bracket 901 can be driven (to the right and forward) to move away from the outlet 201 of the guide rail.
[0074] In some embodiments, a limiting plate 12 located above the first movable member 8 and the second movable member 9 is connected to the mounting base 3.
[0075] The first positioning component 10 includes a first inclined groove 1001 formed on the bottom side of the limiting plate 12, and the first inclined groove 1001 corresponds to the first moving member 8.
[0076] The first inclined slide 1001 is configured to be inclined from front to back and from left to right. The first guide slider 1002 is slidably mounted on the first inclined slide 1001 and extends downward to connect with the first moving member 8.
[0077] The second positioning assembly 11 includes a second inclined groove 1101 formed on the bottom side of the limiting plate 12, and the second inclined groove 1101 corresponds to the second moving member 9.
[0078] The second inclined slide 1101 is configured to be inclined from front to back and from right to left. The second guide slider 1102 is slidably mounted on the second inclined slide 1101. The second guide slider 1102 extends downward to connect with the second moving member 9.
[0079] In this embodiment, the mounting base 3 is further provided with a screw removal part 1201. The screw removal part 1201 is used to push the screw on the first moving member 8 away from the first receiving bracket 801 along the first receiving translation port 802 when the first moving member 8 moves forward, so that the screw on the first moving member 8 can fall into the first guide screw groove 601 below. The screw removal part 1201 is also used to push the screw on the second moving member 9 away from the second receiving bracket 901 along the second receiving translation port 902 when the second moving member 9 moves forward, so that the screw on the second moving member 9 can fall into the second guide screw groove 602 below.
[0080] In some embodiments, the nail release portion 1201 is configured as part of the limiting plate 12, or it can be understood that the rear end of the limiting plate has the nail release portion.
[0081] In this embodiment, each nail feeding tube (first nail feeding tube 4, second nail feeding tube) 5 is provided with an air blowing interface 13. The air blowing interface 13 is used to connect and communicate with the air blowing tube of an external air blowing system so that after the screw falls into the corresponding nail feeding tube, the external air blowing system blows air to blow the screw along the nail feeding tube to the position where the screw is needed.
[0082] An external air blowing system can blow air into a specific screw feeding tube through a corresponding air blowing pipe to deliver the screws inside the corresponding screw feeding tube.
[0083] In this embodiment, when the first receiving bracket 801 is removing screws, the second receiving bracket 901 can be simultaneously driven to the guide rail outlet 201 to continue receiving the arranged screws. Through structural improvements, the traditional reciprocating stroke for feeding one screw is decomposed into a reciprocating stroke for feeding one screw by the first receiving bracket 801 and a reciprocating stroke for feeding one screw by the second receiving bracket 901, enabling sequential feeding of two screws. This allows two screws to be sequentially conveyed in one reciprocating stroke, reducing the feeding interval time by half and greatly improving the screw feeding efficiency of the pneumatic screw feeder.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
