DETAILED DESCRIPTION

[0020] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0021] Please refer to Figures 1 to 3 , a nut automatic directional feeding mechanism, including a nut feeding assembly and a nut ejecting assembly, the discharge port of the nut feeding assembly is connected to the ejecting position 122 of the nut ejecting assembly; the nut ejecting assembly includes an ejection cylinder 1, an ejection sleeve 2, an ejection rod 3 and a positioning claw 4 arranged on the lower side of the ejecting position 122, the driving end of the ejection cylinder 1 is connected to the ejection rod 3, the ejection sleeve 2 is movably arranged on the ejecting position 122, and the ejection sleeve 2 is sleeved with the ejection rod 3; the positioning claw 4 is connected to the ejection sleeve 2, and the clamping end of the positioning claw 4 is against the ejecting position 122.

[0022] As can be seen from the above description, the beneficial effects of the present invention are as follows: the nut is conveyed to the ejection position 122 of the nut ejection assembly by the nut feeding assembly, the nut is limitedly clamped by the clamping end of the positioning air claw 4, and then the ejection cylinder 1 drives the ejection rod 3 to make it protrude from the ejection sleeve 2 and penetrate into the center hole of the nut to further position the nut, after which the driving end of the ejection cylinder 1 continues to push and drive the ejection sleeve 2, the positioning air claw 4, and the nut clamped by the positioning air claw 4 to move upward to the locking nut electric screwdriver head, and the locking nut electric screwdriver head performs the nut picking operation. This design can position the outer diameter and center hole of the nut respectively by the positioning air claw 4 and the ejection rod 3 during the ejection process, without the need for the locking nut electric screwdriver head to rotate to match the nut, thereby ensuring the accuracy of the relative position of the nut and the locking nut electric screwdriver head and improving the picking efficiency of the locking nut electric screwdriver head.

[0023] Furthermore, the nut ejecting assembly further includes an ejection spring 5 , which is sleeved on the ejection sleeve 2 , and two ends of the ejection spring 5 respectively abut against the ejection position 122 and the ejection sleeve 2 .

[0024] From the above description, it can be seen that when the driving end of the ejector cylinder 1 is ejected, the ejector sleeve 2 and the ejector rod 3 move upward, and the ejector spring 5 is compressed; when the screw-locking electric screwdriver head completes the material picking, the driving end of the ejector cylinder 1 retracts, and the ejector spring 5 releases the elastic force to ensure that the ejector sleeve 2 returns to its initial position to prevent it from getting stuck when it retracts.

[0025] Furthermore, the nut ejecting assembly also includes a clamping sleeve 6 and a moving block 7. The lower end of the ejection sleeve 2 is connected to the clamping sleeve 6, and the lower end of the ejection rod 3 is connected to the moving block 7. The moving block 7 is movably arranged in the clamping sleeve 6.

[0026] From the above description, it can be seen that through the design of the clamping sleeve 6 and the moving block 7, when the ejection cylinder 1 is ejected, the ejection rod 3 can be driven to protrude from the ejection position 122 to position the center hole of the nut, and then the ejection rod 3 is driven to move under the drive of the ejection cylinder 1, and the moving block 7 of the ejection rod 3 moves to the end of the clamping sleeve 6 in the clamping sleeve 6 of the ejection sleeve 2, thereby driving the positioning claw 4 of the ejection sleeve 2 to move upward, so that the positioned nut can be moved to the electric screwdriver head of the lock nut located above for material removal.

[0027] Furthermore, the nut ejecting assembly also includes a connecting spring 8, which is connected between the lower end of the ejection rod 3 and the driving end of the ejection cylinder 1.

[0028] From the above description, it can be seen that when the driving end of the ejection cylinder 1 is ejected, the connecting spring 8 transmits the force, so that the ejection rod 3 and the ejection sleeve 2 are both ejected to the ejection position 122, and the connecting spring 8 is compressed at the same time; when the driving ring of the ejection cylinder 1 retracts, the connecting spring 8 releases the elastic force to make the ejection rod 3 quickly return to its initial state.

[0029] Furthermore, a slide rail 9 is connected to one side of the ejection cylinder 1 , and a slider 10 is connected to one side of the positioning claw 4 , and the slider 10 is movably matched with the slide rail 9 .

[0030] As can be seen from the above description, the slide rail 9 of the ejection cylinder 1 cooperates with the slider 10 of the positioning claw 4 to ensure accurate upward movement of the positioning claw 4 during the ejection process.

[0031] Furthermore, it also includes an optical fiber 11, which is arranged on the upper side of the top material position 122.

[0032] As can be seen from the above description, the optical fiber 11 is used to determine whether there is a nut on the ejection position 122 to determine whether to start the ejection cylinder 1 to perform the material removal operation.

[0033] Furthermore, the nut pushing assembly also includes a nut feed plate 12, which is provided with a nut feed trough 121. The nut feed trough 121 is connected to the discharge port of the nut feeding assembly, and the pushing position 122 is provided at the end of the nut feed trough 121.

[0034] From the above description, it can be seen that the nut feed plate 12 is provided with a nut feed trough 121 which is connected to the discharge port of the nut feeding assembly. The nuts are guided by the nut feed trough 121 to move to the top feeding position 122 for the top feeding operation.

[0035] Furthermore, the nut pushing assembly also includes a nut limiting plate 13 , and a nut limiting plate 13 is provided on both sides of the nut feeding groove 121 .

[0036] It can be seen from the above description that the nut moving in the nut feeding trough 121 is limited by the nut limiting plate 13 to ensure directional movement.

[0037] Furthermore, the positioning claw 4 includes a claw cylinder 41, a claw connecting block 42 and a limit block 43. The driving end of the claw cylinder 41 is connected to the claw connecting block 42. The claw connecting blocks 42 are respectively arranged on both sides of the top material position 122. The limit block 43 is connected to the end of the claw connecting block 42 away from the claw cylinder 41, and the limit block 43 is against the nut on the top material position 122.

[0038] As can be seen from the above description, the two air gripper connecting blocks 42 are driven to move toward or away from each other by the air gripper cylinder 41 , so that the limit block 43 can clamp or loosen the nut at the top material position 122 .

[0039] Furthermore, the nut ejecting assembly also includes a support plate 14, and the ejection cylinder 1 is arranged on the support plate 14; the support plate 14 includes two connecting plates and a reinforcing rib, the two connecting plates are vertically connected, and the reinforcing rib is connected between the two connecting plates.

[0040] As can be seen from the above description, the support plate 14 serves as a supporting structure for the ejection cylinder 1 . Its L-shaped structure vertically connected by two connecting plates and its reinforcing rib design ensure support stability.

[0041] Please refer to Figures 1 to 3 , the first embodiment of the present utility model is:

[0042] A nut automatic directional feeding mechanism comprises a nut feeding assembly and a nut pushing assembly, wherein the discharge port of the nut feeding assembly is connected to the pushing position 122 of the nut pushing assembly.

[0043] The nut ejecting assembly includes an ejection cylinder 1, an ejection sleeve 2, an ejection rod 3, a positioning air claw 4, an ejection spring 5, a clamping sleeve 6, a moving block 7, a connecting spring 8, a nut feed plate 12, an optical fiber 11, a nut limiting plate 13 and a support plate 14, which are arranged on the lower side of the ejection position 122.

[0044] The support plate 14 includes two connecting plates and a reinforcing rib, wherein the two connecting plates are vertically connected and the reinforcing rib is connected between the two connecting plates. One side of the support plate 14 is connected to the ejection cylinder 1, and the upper end of the support plate 14 is connected to the nut feed plate 12.

[0045] The nut feed plate 12 is provided with a nut feed trough 121, flanked by nut stop plates 13. The nut feed trough 121 is connected to the outlet of the nut feeding assembly, and a top feed position 122 is located at the end of the nut feed trough 121. The optical fiber 11 is positioned above the top feed position 122. Specifically, the nut feeding assembly includes a nut feeder vibrating plate and a nut feeder linear vibrator, through which nuts are sequentially transferred to the nut feed plate 12.

[0046] The driving end of the ejection cylinder 1 is connected to the ejection rod 3. The ejection sleeve 2 is movably mounted on the ejection position 122. The upper end of the ejection sleeve 2 has a rough surface. The ejection sleeve 2 is sleeved with the ejection rod 3. The positioning claw 4 is connected to the ejection sleeve 2, and the clamping end of the positioning claw 4 abuts against the ejection position 122.

[0047] The ejection spring 5 is sleeved on the ejection sleeve 2, with its two ends respectively abutting against the ejection level 122 and the ejection sleeve 2. A clamping sleeve 6 is connected to the lower end of the ejection sleeve 2, and a movable block 7 is connected to the lower end of the ejection rod 3. The movable block 7 is movably disposed within the clamping sleeve 6. The connecting spring 8 is connected between the lower end of the ejection rod 3 and the driving end of the ejection cylinder 1.

[0048] Specifically, a connecting spring 8 and an ejection spring 5 are arranged in a coordinated manner. The connecting spring 8 has a larger wire diameter than the ejection spring 5. When the driving end of the ejection cylinder 1 moves upward, the connecting spring 8 transmits force to move the ejection rod 3 and the ejection sleeve 2 upward to protrude above the ejection level 122. During this process, both the connecting spring 8 and the ejection spring 5 are compressed. When the driving end of the ejection cylinder 1 retracts, the connecting spring 8 and the ejection spring 5 release their elastic force, allowing the ejection rod 3 and the ejection sleeve 2 to quickly return to their original position, preventing any jamming.

[0049] One side of the ejection cylinder 1 is connected to a slide rail 9 , and one side of the positioning claw 4 is connected to a slider 10 , and the slider 10 is movably matched with the slide rail 9 .

[0050] The positioning air gripper 4 includes an air gripper cylinder 41, an air gripper connecting block 42 and a limit block 43. The driving end of the air gripper cylinder 41 is connected to the air gripper connecting block 42. The air gripper connecting blocks 42 are respectively arranged on both sides of the top material position 122. The limit block 43 is connected to the end of the air gripper connecting block 42 away from the air gripper cylinder 41. The limit block 43 is against the nut on the top material position 122.

[0051] In summary, the automatic directional feeding mechanism for nuts provided by the present invention conveys nuts to the ejection position of the nut ejection assembly through the nut feeding assembly, limits and clamps the nuts through the clamping end of the positioning air claw, and then drives the ejection rod by the ejection cylinder to protrude from the ejection sleeve and penetrate into the center hole of the nut to further position the nut. Thereafter, the driving end of the ejection cylinder continues to push and drive the ejection sleeve, the positioning air claw, and the nut clamped by the positioning air claw to move upward to the locking nut electric screwdriver head, which then performs the nut retrieving operation. This design can position the outer diameter and center hole of the nut respectively through the positioning air claw and the ejection rod during the ejection process, without the need for the locking nut electric screwdriver head to rotate to match the nut, thereby ensuring the accuracy of the relative position of the nut and the locking nut electric screwdriver head and improving the retrieving efficiency of the locking nut electric screwdriver head.
