DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 5 As shown, a screw conveying and positioning device according to a preferred embodiment of the present invention comprises a base 1 and a discharging module 2, a feeding module 3, a positioning module 4, and a reinforcement module 5 arranged above the base 1, and the discharging module 2, the feeding module 3, the positioning module 4, and the reinforcement module 5 are respectively connected to the control module. Specifically, the discharging module 2 comprises a vibration disk 21 for vibrating out the screws 6, and the feeding module 3, the positioning module 4, and the reinforcement module 5 are all located on one side of the vibration disk 21, and the positioning module 4 is located above the feeding module 3. The screw conveying and positioning device of the present invention can quickly and accurately convey the screws 6 to the nail mold through the interaction between the discharging module 2, the feeding module 3, the positioning module 4, and the reinforcement module 5, so that the robot with the tightening shaft can more accurately suck the nails away to complete the operation, with a novel design, cost and space saving, and improved production efficiency.

[0032] like Figure 6 As shown, the positioning module 4 includes at least two recesses 44 for placing screws 6, a second connecting assembly, and a nail blowing assembly 45 located above the second connecting assembly. Specifically, the second connecting assembly includes a support block 41, a connecting rod 42, and a concave module 43. The connecting rod 42 is arranged on one side of the support block 41, and the concave module 43 is connected to the connecting rod 42 and is located above the side of the support block 41. The recess 44 is located at the edge of the concave module 43. When the vibration disk 21 vibrates the screw 6 out, the recess 44 corresponds to the nail outlet of the vibration disk 21, and the screw 6 can fall into the recess 44. According to the actual needs of production, the number of recesses 44 can be increased or decreased accordingly. In this embodiment, the number of recesses 44 is preferably two. In order to better ensure the precise positioning of the screw 6, the concave module 43 can be designed according to the size of the screw rod of the screw 6. In this embodiment, the recess 44 is preferably designed to be triangular in shape, and the two sides of the recess 44 are in contact with the screw rod of the screw 6. In addition, the support block 41 is square with a hollow circle in the middle, and limit blocks 7 are provided on both sides of the support block 41. This design can not only be used for zero point correction of the feeding module 3, but also prevent the feeding module 3 from overtravel during operation, thus playing a limiting role.

[0033] like Figure 7As shown, in order to improve the precise positioning of the screw 6, the feeding module 3 includes a servo assembly 31, which is used to send the screw 6 in the recess 44 to the reinforcement module 5 for fixing. The servo assembly 31 includes a servo motor, a screw rod, a slider and a servo control mechanism. The repeatability of the servo assembly 31 can reach plus or minus 0.02, which greatly improves the accuracy of the screw 6 while saving cost and space. The servo assembly 31 can also correspond to the receiving screw 6 by changing the stroke, and the distance between the two screws 6 can be arbitrarily changed within the range of the feeding module 3 according to the needs. In addition, the feeding module 3 also includes a support frame 32, a first connecting assembly and a first sensor 33. The support frame 32 is fixed above the base 1, and the positioning module 4 and the reinforcement module 5 are both located above the support frame 32. The first connecting assembly includes a support column 34 and a nail receiving plate 35. The support column 34 is connected to the first sensor 33. The nail receiving plate 35 is on the same side as the vibration plate 21. The number of nail receiving plates 35 can be at least one.

[0034] In addition, in order to better improve production efficiency, a nail blowing assembly 45 is specially designed to blow the remaining screws 6 due to failed nail removal into the nail receiving tray 35. Specifically, the nail blowing assembly 45 includes a first fixing frame 451 and a second fixing frame 452 arranged up and down, the number of the first fixing frame 451 is two, the second fixing frame 451 is T-shaped, and the two first fixing frames 451 are respectively located at both ends of the horizontal direction of the second fixing frame 452. When the robot with a tightening shaft fails to remove the nail, it is possible that the screw 6 will remain on the concave module 43. If it is not handled immediately, it will affect the normal operation of the screw conveying and positioning device. At this time, the nail blowing assembly 45 can blow away the remaining screws 6 due to the failure and drop them into the nail receiving tray 35.

[0035] like Figure 8As shown, the reinforcement module 5 includes a first cylinder 51 and a clamping assembly 52. ​​The clamping assembly 52 is pushed toward the direction of the screw 6 and clamped under the action of the first cylinder 51. The clamping assembly 52 includes a first clamping block 521 and a second clamping block 522 that are mirror-set, and the first clamping block 521 and the second clamping block 521 are both L-shaped. The reinforcement module 5 also includes a baffle assembly 53, a clamping plate assembly 54, a third connecting assembly, a second sensor 55 and a second cylinder 56. The baffle assembly 53 is directly opposite to the clamping assembly 52. ​​The second cylinder 56 is connected to the clamping plate assembly 54. The second sensor 55 and the clamping plate assembly 54 are respectively located on both sides of the clamping assembly 52, and the second sensor 55 is directly opposite to the nail outlet of the vibration plate 21. The baffle assembly 53 includes a first baffle 531 and a second baffle 532 that are arranged up and down. The first baffle 531 is provided with a screw hole that matches the notch 44, and the second baffle 532 is fixed to the support frame 32. The baffle assembly 53 is arranged between the recessed module 43 and the clamping assembly 52 to prevent the screw 6 from falling during the transportation and positioning process, thereby protecting the screw 6. The clamping assembly 54 includes a first clamping plate 541 and a second clamping plate 542 arranged front and rear, a second cylinder 56 and a second clamping plate 542 are respectively arranged on both sides of the first clamping plate 541, and the second clamping plate 542 is fixed to the support frame 32 through the first pillar 8. When the screw 6 is in the recess 44, there is a gap, which will cause shaking, so that the tightening shaft cannot smoothly remove the screw 6. Therefore, at this time, under the action of the second cylinder 56, the clamping assembly 54 can fix the screw 6. In addition, the third connecting assembly includes an L-shaped connecting plate 57, which is fixed to the support frame 32 through the second pillar 9, and the second sensor 55 is arranged on the connecting plate 57. The second sensor 55 is directly opposite to the screw outlet of the vibration plate 21. When the screw 6 is vibrated out and falls into the notch 44, the second sensor 55 is used to determine whether the notch 44 receives the screw 6, and then feeds back the information to the control module for the next operation. The design of the reinforcement module 5 can make the screw 6 in the notch 44 more stable.

[0036] The working principle of the screw conveying and positioning device described in the present invention is as follows: first, the vibration plate 21 vibrates out the first screw 6, and the first screw 6 falls into the first recess 44 corresponding to the nail outlet; after the second sensor 55 located above the nail outlet confirms the position of the first screw 6, the servo component 31 drives the positioning module 4 to move forward a distance to ensure that the second screw 6 falls into the second recess 44 corresponding to the nail outlet; then, the servo component 31 drives the positioning module 4 to continue to move forward to ensure that the positions of the first screw 6 and the second screw 6 are just aligned with the clamping component 52 of the reinforcement module 5; then, the reinforcement module 5 works, the first cylinder 51 drives the clamping component 52 to move forward, and the clamping component 52 fixes the screw 6; at the same time, the second cylinder 56 drives the clamping plate component 54 to reinforce the screw 6; thereafter, after tightening the shaft to take out the nail, the first sensor 33 detects whether both screws 6 have been taken out; if there is a situation where the nail removal is unsuccessful, at this time the nail blowing component 45 operates to blow the remaining screws 6 in the recessed module 43 into the nail receiving plate 35.

[0037] The screw conveying and positioning device of the present invention has novel structural design, low noise and failure rate, high repetition accuracy and long service life. It can be used in an automatic assembly line to quickly and accurately convey screws to a tightening shaft, thereby improving the quality of screw conveying and production efficiency.
