When the storage groove aligns with the discharge end of the feed pipe, the storage groove receives the screws from the feed pipe. When the storage groove aligns with the clamp, the blanking component pushes the screws in the storage groove towards the clamp. It can be understood that when the lifting plate is at a high position, the storage groove aligns with the discharge end of the feed pipe, and a screw in the feed pipe can enter the storage groove from the discharge end. Then, the lifting plate drives the storage seat to descend. When the storage seat descends, the storage groove no longer aligns with the discharge end of the feed pipe, and at the same time, the side of the discharge seat can block the discharge end of the feed pipe to prevent the screws in the feed pipe from falling from the discharge end.

[0041] The following describes a feeding device and a screw grooving machine according to an embodiment of the present utility model with reference to the drawings.

[0042] Refer to Figure 1 and Figure 2 A screw grooving machine according to an embodiment of the present utility model includes a feeding device, and the feeding device includes a frame 100, a material transferring mechanism, and a driving mechanism.

[0043] For the frame 100, a feeding pipe 110 and a fixture 120 are provided on the frame 100. The feeding pipe 110 extends downward from top to bottom. The discharging end of the feeding pipe 110 is located at the bottom end of the feeding pipe 110. The discharging end of the feeding pipe 110 and the fixture 120 are arranged vertically. The feeding pipe 110 is used for conveying screws, and the fixture 120 is used for clamping screws.

[0044] In this embodiment, by providing the feeding pipe 110 on the frame 100, the feeding pipe 110 extends downward from top to bottom, and the discharging end of the feeding pipe 110 is located at the bottom end of the feeding pipe 110. The feeding pipe 110 is used for conveying screws. Thus, when the screws are fed through the feeding pipe 110, the screws can slide from the top to the discharging end at the bottom along the feeding pipe 110 by their own gravity. Furthermore, automatic feeding is achieved.

[0045] In this embodiment, a fixture 120 is provided on the frame 100. The discharge end of the feed pipe 110 is arranged vertically with the fixture 120. The fixture 120 is used to clamp the screws. Thus, the fixture 120 can clamp and rotate the screws so that the slotting machine can slot the screws. At the same time, the discharge end of the feed pipe 110 is arranged vertically with the fixture 120, which is convenient for the screws to be transferred from the discharge end of the feed pipe 110 to the fixture 120.

[0046] In some specific embodiments, a vibrating bowl is further provided on the frame 100, and the discharge port of the vibrating bowl is connected to the feed port of the feed pipe 110.

[0047] Refer to Figure 3 、 Figure 4 and Figure 5 For the material transfer mechanism, the material transfer mechanism includes a lifting plate 130 slidably arranged up and down on the frame 100, a storage seat 140 arranged on the lifting plate 130, and a pusher assembly 150. The side of the storage seat 140 is used to block the discharge end of the feed pipe 110. A storage groove 160 is arranged at the bottom of the side of the storage seat 140. The lifting plate 130 drives the storage seat 140 to lift and lower so that the storage groove 160 is aligned with the discharge end of the feed pipe 110 or the fixture 120. When the storage groove 160 is aligned with the discharge end of the feed pipe 110, the storage groove 160 receives the screws from the feed pipe 110. When the storage groove 160 is aligned with the fixture 120, the pusher assembly 150 pushes the screws in the storage groove 160 towards the fixture 120.

[0048] It can be understood that when the lifting plate 130 is at the high position, the storage groove 160 is aligned with the discharge end of the feed pipe 110, and a screw in the feed pipe 110 can enter the storage groove 160 from the discharge end. Then, the lifting plate 130 drives the storage seat 140 to descend. When the storage seat 140 descends, the storage groove 160 is no longer aligned with the discharge end of the feed pipe 110, and at the same time, the side of the discharge seat can block the discharge end of the feed pipe 110 to prevent the screws in the feed pipe 110 from falling from the discharge end. When the lifting plate 130 descends to the low position, the storage groove 160 is aligned with the fixture 120. Thus, it is convenient for the pusher assembly 150 to push the screws in the storage groove 160 towards the fixture 120.

[0049] In some specific embodiments, a limiting wall is provided on one side of the storage groove 160 away from the discharge end of the feed pipe 110. The limiting wall is used to limit the screws. Thus, the storage groove 160 can only store one screw, and further, the material transfer mechanism can transfer one screw each time.

[0050] In some specific embodiments, the storage base 140 includes a first base body 210, a clamping block 220, and a second spring 230. The clamping block 220 is hinged to the bottom of the first base body 210. An upper half groove 240 is provided at the bottom of the first base body 210, and a lower half groove 250 is provided at the top of the clamping block 220. The upper half groove 240 and the lower half groove 250 cooperate to form a storage groove 160. The second spring 230 is disposed between the first base body 210 and the clamping block 220, and the second spring 230 is used to drive the clamping block 220 to approach the first base body 210 so that the clamping block 220 and the first base body 210 cooperate to clamp the screw.

[0051] It can be understood that by hinging the clamping block 220 to the bottom of the first base body 210, the clamping block 220 can swing, thereby facilitating the cooperation between the clamping block 220 and the first base body 210 to clamp the screw, and further avoiding the screw falling off from the storage groove 160 when the storage base 140 moves the screw.

[0052] Further, the frame 100 is provided with a limiting block 260. The limiting block 260 is located on one side of the discharge end of the feed pipe 110. The bottom of the limiting block 260 abuts against the clamping block 220 to drive the clamping block 220 away from the first base body 210 so that the clamping block 220 is loosened.

[0053] It can be understood that when the lifting plate 130 rises to the high position, the clamping block 220 abuts against the limiting block 260, and the limiting block 260 drives the clamping block 220 away from the first base body 210. Thus, the clamping block 220 is loosened, the space of the storage groove 160 is increased, and further, it is convenient for the screw of the feed pipe 110 to enter the storage groove 160.

[0054] In some specific embodiments, the ejecting assembly 150 includes an ejecting pin 270, a swing arm 280, and a transmission rod 290. The ejecting pin 270 is horizontally slidably disposed on the storage base 140, and the ejecting pin 270 can penetrate the storage groove 160. The swing arm 280 is hinged to the storage base 140, and the transmission rod 290 drives the swing arm 280 to swing so that the swing arm 280 drives the ejecting pin 270 to eject the screw in the storage groove 160. Thus, through the transmission of the swing arm 280 and the transmission rod 290 to the ejecting pin 270, further, it is convenient for the arrangement of the ejecting assembly 150.

[0055] Further, one of the ejecting pin 270 and the swing arm 280 is provided with a first transmission pin 300, and the other of the ejecting pin 270 and the swing arm 280 is provided with a first transmission chute 310. The first transmission pin 300 and the first transmission chute 310 cooperate for transmission, thereby avoiding jamming between the swing arm 280 and the ejecting pin 270 when the swing arm 280 swings.

[0056] In some specific embodiments, one of the transmission rod 290 and the swing arm 280 is provided with a second transmission pin 320, and the other of the transmission rod 290 and the swing arm 280 is provided with a second transmission chute 330. The second transmission pin 320 and the second transmission chute 330 are engaged for transmission, thereby preventing jamming between the swing arm 280 and the transmission rod 290 when the swing arm 280 swings.

[0057] Referring to Figure 6 and Figure 7 For the driving mechanism, the driving mechanism includes a cam 170 and a first motor 180 that drives the cam 170 to rotate in a direction perpendicular to the lifting plate 130. The lifting plate 130 is provided with a first abutting member 190, and the first abutting member 190 is used to abut against the top of the cam 170. The cam 170 and the first abutting member 190 cooperate to drive the lifting plate 130 to lift and lower.

[0058] It can be understood that the motor drives the cam 170 to rotate. The top of the outer peripheral surface of the cam 170 abuts against the first abutting member 190. When the cam 170 rotates, the first abutting member 190 can lift and lower along the outer peripheral contour of the cam 170. Thus, the cam 170 and the first abutting member 190 cooperate to drive the lifting member to lift and lower. Furthermore, hydraulic power transmission is eliminated, the feeding device is prevented from being affected by the environment, and the stability of the product precision is improved.

[0059] In some specific embodiments, the first abutting member 190 is set as a roller, and the roller is rotatably arranged on the lifting plate 130, thereby reducing the frictional resistance between the first abutting member 190 and the cam 170, and further making the rotation of the cam 170 more labor-saving.

[0060] In some specific embodiments, a first spring 200 is further arranged between the lifting plate 130 and the frame 100. The first spring 200 is used to drive the lifting plate 130 to descend. Thus, under the action of the first spring 200, the first abutting member 190 can always be in contact with the cam 170, so that the first abutting member 190 can follow the trajectory of the cam 170, and further, the movement of the first abutting member 190 is made more stable.

[0061] In some specific embodiments, a third spring 340 is disposed between the swing arm 280 and the lifting plate 130. The third spring 340 is configured to drive one end of the swing arm 280 close to the top pin 270 away from the storage base 140. Thus, the third spring 340 can drive the top pin 270 away from the screw, preventing the top pin 270 from pushing the screw out of the storage groove 160 during the process of the material transfer mechanism moving the screw. Meanwhile, the transmission rod 290 is horizontally slidably connected to the lifting plate 130. A second abutting member 350 is disposed at one end of the transmission rod 290 away from the swing arm 280. A guiding block 360 is disposed on one side of the cam 170. The rotation of the cam 170 drives the guiding block 360 to abut against the second abutting member 350, so that the transmission rod 290 drives one end of the swing arm 280 close to the top pin 270 to approach the storage base 140. Thus, the rotation of the cam 170 can drive the top pin 270 to push the screw out of the storage groove 160. Furthermore, the first motor 180 can drive the lifting of the lifting plate 130 and the ejecting action of the ejecting mechanism simultaneously, reducing the setting of power components and lowering the manufacturing cost.

[0062] In some specific embodiments, a limit pin is disposed at one end of the swing arm 280 away from the top pin 270. The limit pin abuts against and limits the lifting seat. Thus, the cooperation and limitation between the limit pin and the lifting seat can limit the swinging angle of the swing arm 280 driven by the third spring 340, preventing the swing arm 280 from driving the top pin 270 away from the storage base 140.

[0063] In some specific embodiments, a protective cover is further disposed on the frame 100. The protective cover is configured to cover the feeding device. Thus, the protective cover can isolate the feeding device from the operator, and further effectively avoid potential safety hazards.

[0064] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention.
