Description

Technical Field

[0001] The invention relates to the technical field of bar conveying, in particular to an active feeding system based on visual screening of entire columns. Background Art

[0002] Screw assembly has evolved from traditional manual tightening to today's automatic screw machines, increasing efficiency hundreds or even thousands of times. Automatic screw machines include screw aligners, screw alignment machines, and screw feeders, and their primary function is to deliver screws to designated locations.

[0003] CN111099318A discloses a rod feeding system with active loading and a hanging head, which includes a base, a hopper, a conveying part and a controller, wherein the hopper and the conveying part are arranged on the base; the hopper part includes a hopper, a collecting wheel and a first driving mechanism; the hopper includes a dropping area, a collecting area and an inclined surface, wherein the dropping area is higher than the collecting area, and the inclined surface connects the dropping area and the collecting area; the collecting wheel is connected to the hopper at a vertical or inclined angle, and the collecting wheel is connected to the first driving mechanism; the lower edge of the circumferential wall of the collecting wheel is arranged in the collecting area and is connected to the lowest edge of the inclined surface; a plurality of blades are arranged on the inner circumferential wall of the collecting wheel; the conveying part includes a turntable, a mounting seat and a second driving mechanism, and the turntable is arranged in the dropping area and is arranged on the mounting seat at a horizontal to inclined angle. The beneficial effects of the present invention are modular design, compact and coordinated structure, stable operation and high work efficiency, which meet the diverse needs of customers for feeding systems.

[0004] In this solution, during the rotation of the turntable of this system, the material is passively sucked into the turntable support holes. The flow rate and suction force of each suction hole through the vacuum are related to the aperture of the support hole. Materials that are too large or too heavy are not easily attracted, which can easily lead to discontinuous feeding on the turntable. This invention fails to disclose this problem.

[0005] CN213922953U discloses a posture adjustment unit and active feeding system for large nail cap short rods with hanging heads, comprising a linear track, a third drive mechanism, and a track adjustment mechanism. The third drive mechanism is connected to a transmission seat, and the first and third transmission support plates are arranged vertically or at a predetermined angle, while the second transmission support plate is arranged horizontally. The lower end of the first transmission support plate is connected to the transmission seat, and the upper end is provided with a first long waist-shaped hole, the first long waist-shaped hole being parallel to the contact portion, and the first adjustment screw passing through the first long waist-shaped hole is connected to the second transmission support plate. The second transmission support plate is provided with a second long waist-shaped hole in a direction perpendicular to the contact portion, and the second adjustment screw passing through the second long waist-shaped hole is connected to the upper end of the third transmission support plate. The third transmission support plate is provided with a third long waist-shaped hole, and the third adjustment screw passing through the third long waist-shaped hole is connected to the linear track. Advantageously, the modular design is adopted, resulting in a compact and coordinated structure, stable operation, and high work efficiency.

[0006] In this solution, the structure of the support plate is only suitable for feeding large-cap short-rod bar materials with hanging heads, and its compatibility is poor. This technology cannot be used to achieve stable feeding for special forms of long-rod bar materials with hanging heads.

[0007] In the above-mentioned prior art, there are some problems with the continuity and compatibility of material feeding: the probability of empty material feeding may increase, and the special long rod-shaped material with a hanging head cannot ensure continuous feeding.

[0023] Optionally, a vacuum adsorption device is also included, which is pre-tightened and fitted on the turntable by a spring and is located on the extension line of the material movement direction, and the vacuum adsorption device can intermittently dock with the support hole to provide vacuum adsorption force to adsorb the material.

[0025] The beneficial effects of the present invention are as follows:

[0026] The present invention has a compact and reasonable structure and is easy to operate. By adopting a modular design, the structure is compact and coordinated, the operation is stable and the work efficiency is high. The size ratio restrictions on the bars with hanging heads are relaxed. The posture of the bars with hanging heads in the linear track is judged by vision to see whether it is correct. Those that do not meet the requirements for picking up the support holes will be blown off from the linear track. This ensures with a high probability that the bars with hanging heads enter the support holes in a posture that meets the requirements for picking up the support holes, further stabilizing the feeding rhythm and meeting the diverse needs of customers for the feeding system.

[0027] At the same time, the present invention also has the following advantages:

[0028] 1. The linear track is designed in a V shape and can realize vibration feeding, and a blowing mechanism for blowing out the material is provided on the side wall of the linear track.

[0029] 2. The visual camera unit is another highlight of this application. It is located above the track screening unit and electrically cooperates with the blowing mechanism to monitor the direction of materials in the area in real time, and activates the blowing mechanism to blow out materials after detecting materials with abnormal directions.

[0030] 3. The material distribution part is the biggest highlight of this implementation. Through the improvement of its structure, the overall structure is more compact and the material distribution effect is better. The material distribution part includes a turntable that can rotate intermittently. The turntable and the linear track are on the same plane. The turntable is provided with a plurality of support holes along the circumference that can dock with the linear track and be used to accommodate materials.

[0031] 4. By adopting vibration reduction measures to reduce the vibration of the visual camera, the service life is prolonged and the camera is more stable, reducing the reduction in detection stability caused by camera shake.

[0032] 5. There is an inclination angle of 0-45 degrees between the linear track and the horizontal plane. Based on the material conveying power, the optimal angle in actual use is 0-5 degrees. Too large an inclination angle will cause the material to move too fast under the action of gravity, which is not conducive to screening, and it is also prone to pile-up.

[0033] 6. If the rod of the bar with a hanging head cannot be parallel to the moving direction, that is, the rod head (the head end of the rod) will hang on the linear track, then the support hole is connected to the rod of the bar with a hanging head in a manner inclined to the lower left, and the bar with a hanging head can also be inserted into the support hole under the action of gravity. At this time, the loading of the bar with a hanging head can be achieved even in the absence of a vacuum adsorption device.

[0034] 7. The vacuum adsorption device is used to cooperate with the turntable to achieve vacuum adsorption of the material. The vacuum adsorption device is pre-tightened on the turntable by a spring and is located on the extension line of the material movement direction. The vacuum adsorption device can intermittently dock with the support hole to provide vacuum adsorption force to adsorb the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0050] like Figure 1 As shown, the active feeding system based on visual screening of the whole column in this embodiment includes a hopper part 2, a track screening part 3, a visual camera part 4, a material dividing part 5 and a vacuum adsorption device, which can realize the effects of automatic discharging, one-by-one conveying, screening and removal, and vacuum adsorption loading of materials, thereby improving work efficiency.

[0051] It also includes a base plate 1 , on which a hopper portion 2 , a track screening portion 3 and a material distribution portion 5 are arranged. The material in this embodiment is a rod 50 with a hanging head.

[0052] The following is a detailed description of each device.

[0053] like Figure 11As shown, in this embodiment, the hopper part 2 is used to transport materials. The hopper part 2 includes a hopper 6, a collecting drum 7 and a first driving mechanism 8. The hopper 6 is arranged on the collecting drum 7 at an inclined predetermined angle. A number of blades are arranged in the collecting drum 7 and connected to the first driving mechanism 8, so that the rods with hanging heads 50 flow into the inside of the collecting drum 7. After the collecting drum 7 rotates, the rods with hanging heads 50 are sent out from low to high, thereby achieving the feeding effect.

[0054] like Figure 3-Figure 4 as well as Figure 13 As shown, in this embodiment, the track screening part 3 is arranged downstream of the hopper part 2 and is used to sort the materials; the track screening part 3 includes a linear track 11, which is designed in a V-shape and can realize vibration feeding, and a blowing mechanism for blowing out the materials is provided on the side wall of the linear track 11;

[0055] The linear track 11 is driven by the second driving mechanism 9 to realize vibratory feeding. The linear track 11 and the second driving mechanism 9 are connected to each other through the support frame 10. The second driving mechanism 9 includes a base 13, a base 18, an armature 16 and an electromagnet 12. Several groups of springs 17 are provided between the base 13 and the base 18. A certain gap is provided between the springs 17. The armature 16 and the electromagnet 12 are opposite and spaced apart. The electromagnet 12 and the base 13 are fixed by screws 14, and then the bottom of the electromagnet 12 is supported by screws 15 to adjust the gap between the electromagnet 12 and the armature 16. The armature 16 is fixed on the base 18.

[0056] The linear track 11 includes a slide plate 19, a first supporting surface 20, a second supporting surface 21, and an air blowing slot 22. The slide plate 19 overlaps the first supporting surface 20 for material entry. A retaining edge 23 is provided on one side of the slide plate 19 to prevent the forward inertial movement of the hanging head rod 50. The slide plate 19 is provided with a first supporting surface 20, which is connected to the second supporting surface 21 in a V-shaped structure. The second supporting surface 21 is connected to the support frame 10.

[0057] like Figure 13 As shown, in this embodiment, the blowing mechanism is one of the improved highlights of the present application. The blowing mechanism includes a blowing gap gasket 49, which is clamped between the first support surface 20 and the second support surface 21 and is connected and fixed by a screw fixing plate 48. The spacing between the first support surface 20 and the second support surface 21 can be adjusted. The blowing gap gasket 49 is provided with at least one blowing slot 22 extending to the linear rail 11, and a plug-in hole is provided on the first support surface 20 or the second support surface 21, and a quick plug-in unit 24 that docks with the blowing gap gasket 49 is connected to the plug-in hole, and the rod 50 with a hanging head that needs to be blown out is blown back from the first support surface 20 to the hopper 6 by inflating the blowing gap gasket 49.

[0058] In this embodiment, Figure 5 As shown, the visual camera unit 4 is another highlight of the present application. It is located above the track screening unit 3 and electrically cooperates with the blowing mechanism to monitor the direction of the materials in the area in real time and activate the blowing mechanism to blow out the materials after detecting materials with abnormal directions.

[0059] Specifically, the visual camera unit 4 includes a camera bracket 25, a shock absorber 26, a camera 27, a light source panel 28, a diffuser panel 29, and a mounting base 30. The camera bracket 25 is connected to the shock absorber 26 to absorb the vibration generated when the second drive mechanism 9 is working. Since the linear track 11 uses vibration for feeding, the vibration here will affect the use effect of the visual camera unit 4. Therefore, by adopting vibration reduction measures, the service life is improved, and the detection stability is reduced due to the shaking of the camera 27.

[0060] At the same time, the camera 27 is connected to the mounting base 30, the light source board 28 is connected to the mounting base 30, and the diffusion plate 29 is covered on the outside with screws. The camera 27 emits light through the light source board 28, and the diffusion plate 29 diffuses the light to achieve the purpose of fill light for the camera. The lens of the camera 27 is aimed at the blowing slot 22 of the track screening part 3 and takes pictures along the upper rear of the material forward direction.

[0061] The camera 27 detects the direction of the material and identifies the material that does not meet the requirements. At the same time, the visual camera part 4 is used in conjunction with the blowing mechanism to accurately blow out the material in the wrong position, thereby facilitating subsequent loading.

[0062] In this embodiment, Figure 7-10 as well as Figure 12 As shown, the material distribution part 5 is the biggest highlight of this embodiment. Through its structural improvement, the overall structure is more compact and the material distribution effect is better. The material distribution part 5 includes a turntable 37 that can rotate intermittently. The turntable 37 and the linear track 11 are on the same plane. The turntable 37 is provided with a plurality of support holes 41 along the circumference that can dock with the linear track 11 and be used to accommodate materials.

[0063] In this embodiment, an inclination angle of 0 degrees to 45 degrees is set between the straight track 11 and the horizontal plane. Based on the material conveying power, the optimal angle in actual use is 0 degrees to 5 degrees. If the inclination angle is too large, the material will move too fast under the action of gravity, which is not conducive to screening, and it is also easy to pile up. When the inclination angle is 5 degrees, it can not only realize the movement of materials, but also ensure that other equipment can have reaction time, thereby better improving the feeding effect.

[0064] In addition, in this embodiment, when the support hole 41 is docked with the linear track 11, the center of the support hole 41 and the axis of the material rod are on the same straight line, which is mainly divided into the following two situations:

[0065] Case 1: In this embodiment, if Figure 12 As shown, the support hole 41 is toward the center of the turntable 37. The rod 50 with a hanging head in this embodiment has a short rod portion, and its rod portion direction is parallel to the moving direction, so the support hole 41 of this shape can facilitate the insertion of materials.

[0066] Case 2: In another embodiment, if the rod portion of the rod 50 with a head cannot be parallel to the moving direction, that is, the rod head (the head end of the rod portion) will hang on the linear track 11, when docking, the support hole 41 is inclined to the lower left (that is, lower than the center of the turntable 37) to dock with the rod portion of the rod 50 with a head. The rod 50 with a head can also be inserted into the support hole 41 under the action of gravity. At this time, the loading of the rod 50 with a head can be achieved even in the absence of a vacuum adsorption device. In addition, it should be noted that the distance between the first support surface 20 and the second support surface 21 cannot be greater than the diameter of the rod portion of the rod 50 with a head, otherwise the rod 50 with a head cannot be docked into the support hole 41.

[0067] In this embodiment, the material distribution part 5 also includes a main body seat 43, a connecting bracket 31, a motor 32 and a groove wheel 34. The connecting bracket 31 is fixed on the base plate 1. The main body seat 43 is arranged on the connecting bracket 31. The output shaft of the motor 32 is connected to gear 1 33. Gear 1 33 engages gear 2 45. Gear 2 45 is coaxially connected to a dial wheel 35. The dial wheel 35 is fixed by a bracket. An origin sensor 44 is arranged below the dial wheel 35 to record the position of the turntable 37. The turntable 37 is rotatably connected to the main body seat 43. The turntable 37 is coaxially connected to the groove wheel 34 through a bearing 36. When the groove wheel 34 rotates intermittently, the turntable 37 also rotates synchronously. A plurality of ventilation holes 42 corresponding to the support holes 41 are provided on the end face of the turntable 37.

[0068] In this embodiment, the vacuum adsorption device is used to cooperate with the turntable 37 to achieve vacuum adsorption of the material. The vacuum adsorption device is pre-tightened on the turntable 37 by a spring and is located on the extension line of the material movement direction. The vacuum adsorption device can intermittently dock with the support hole 41 to provide vacuum adsorption force to adsorb the material.

[0069] The vacuum adsorption device includes a sealing block 39 and a vacuum quick plug 46. The sealing block 39 is slidably set in the through hole opened on the main body seat 43. The sealing block 39 is located on the extension line of the material movement direction and is arranged perpendicular to the vent 42. Both the sealing block 39 and the vacuum quick plug 46 are provided with air holes and are interconnected. At the same time, a telescopic sleeve is connected between the sealing block 39 and the vacuum quick plug 46, and a spring 40 is sleeved on the telescopic sleeve. Under the action of the spring 40, the sealing block 39 is pressed against the side of the vent 42. The other end of the vacuum quick plug 46 is connected to the vacuum machine.

[0070] The main seat 43 is located between the turntable 37 and the linear track 11 and has a plurality of blowing holes 47 on its side wall. The other end of the blowing hole 47 is connected to the blowing equipment. When the material is not in stable contact with the supporting hole 41, air is blown through the blowing hole 47 to make the material fall into the hopper 6.

[0071] A material detection sensor 38 is provided on the main body seat 43 and faces the highest point of the turntable 37 , for detecting whether there is material when the turntable 37 moves to the highest point.

[0072] The specific engineering process is as follows:

[0073] Figures 1-13 The active feeding system based on visual screening is characterized by comprising a base plate 1, a hopper part 2, a track screening part 3, a visual camera part 4 and a material distribution part 5; the hopper part 2, the track screening part 3 and the material distribution part 5 are arranged on the base plate 1; the hopper part 2 includes a hopper 6, a collecting roller 7 and a first driving mechanism 8; Figure 11 It can be seen that the hopper 6 is set on the collecting drum 7 at an inclined predetermined angle. Several blades are arranged in the collecting drum 7 and connected to the first driving mechanism 8, so that the rods 50 with hanging heads flow into the collecting drum 7. After the collecting drum 7 rotates, the rods 50 with hanging heads are sent out from low to high. After reaching the sliding plate 19 of the track screening part 3, the rods 50 with hanging heads slide downward into the V-shaped structural groove formed by the first supporting surface 20 and the second supporting surface 21. The vibration generated by the second driving mechanism 9 causes the material to be transported toward the turntable 37. During the transportation process, the visual camera part 4 is connected to the controller. The conveying position and current posture of the rod 50 with a head are captured in real time. After AI deep learning, when the rod 50 with a head is about to reach the vicinity of the blowing slot 22, it is judged in real time whether the current posture of the rod 50 with a head is correct, and the blowing slot 22 is controlled to blow out the rod 50 with an incorrect posture from the V-shaped structural groove, leaving only the material with the correct posture to pass through the blowing slot 22; after the rods 50 with heads are arranged in the correct posture, the posture of each rod body of the rod 50 with a head on the track can be kept consistent and conveyed to the vicinity of the screw fixing plate 48 of the turntable 37 of the material distribution part 5.

[0074] Combine Figure 13 It can be seen that one or more blowing slots 22 are provided on the blowing gap gasket 49, which are arranged between the first supporting surface 20 and the second supporting surface 21 to create a cavity airway inside. When the air source is introduced for blowing, the blowing slots 22 will spray out the gas, causing the rod 50 with the hanging head to be blown off.

[0075] Combine Figure 7-10It can be seen that the material distribution part 5 includes a connecting bracket 31, a motor 32, a gear 1 33, a groove wheel 34, a dial 35, a bearing 36, a turntable 37, a material detection sensor 38, a sealing block 39, a spring 40, a vacuum quick plug 46, a main body seat 43, an origin sensor 44, a gear 2 45, etc. The motor 32 is connected to the gear 1 33 to drive the groove wheel 34 to rotate. The groove wheel 34 is connected to the dial 35 to engage the groove wheel 34 to perform intermittent rotational motion. The groove wheel 34 is connected to the turntable 37 and also performs intermittent rotational motion.

[0076] Combine Figure 10 It can be seen that a vent hole 42 of corresponding size is opened on the side of the supporting hole 41 corresponding to the turntable 37. The side of the turntable 37 is pressed and sealed by the sealing block 39 through the spring 40. The sealing block 39 is connected to the vacuum quick plug 46. At this time, a vacuum air source is introduced to the outside of the vacuum quick plug 46, so that a vacuum is continuously generated inside the supporting hole 41, thereby sucking the rod body of the hanging head rod 50 near the supporting hole 41 of the turntable 37 into the hole.

[0077] Combine Figure 12 It can be seen that when the posture of the rods 50 with heads arranged in the track screening part 3 is incorrect, the rods 50 with heads can also be sucked up through the support holes 41 of the turntable 37. As the turntable 37 rotates, because the rod body of the rod 50 with heads has not entered the support holes 41, the rod body cannot be stuck in the hole, and the blowing holes 47 can easily blow off the rods 50 with heads on the support holes 41, thereby preventing the rods 50 with heads in the wrong posture from being transported to the position of the support holes 41.

[0078] When the support hole 41 of the turntable 37 rotates to the position of the material detection sensor 38, the material detection sensor 38 is connected to the controller to detect whether there is a rod 50 with a hanging head in the support hole 41. If there is a rod 50 with a hanging head in the support hole 41, a signal is sent to the controller to stop the motor 32 from rotating. The turntable 37 also stops rotating at the same time. After the material detection sensor 38 detects that the rod 50 with a hanging head is taken out, the controller makes the motor 32 continue to rotate and the system continues to work.

[0079] Compared with the traditional feeding method, the feeding system has poor compatibility with multiple specifications of the rods 50 with heads. Its track screening part 3 is usually a mechanical structure to screen the posture of the rods 50 with heads. The parts it consists of are numerous and complex. It is cumbersome to adjust the parts of the track screening part 3 to match the size of the rods 50 with heads. Usually, the adjustment of the track screening part 3 can only be applied to a single specification of the rods 50 with heads. For the present invention, the track screening part 3 has only a single V-shaped structure, and the posture of the rods 50 with heads is mainly judged by the camera vision camera part 4 above the track screening part 3, so that the overall mechanical structure becomes simple and has good compatibility. When changing the size of different rods 50 with heads, there is no need to adjust more parts of the track screening part 3, thereby achieving the purpose of rapid changeover.

[0080] The purpose of the present invention is to provide a feeding system for materials with hanging head rods 50, which mainly judges the real-time correct posture of the materials based on vision, and blows the materials with incorrect postures off the track by blowing, thereby improving the success rate of screening with correct postures, and ensuring that the rods 50 with hanging heads enter the support hole 41 with a posture that meets the picking requirements of the support hole 41, and are thus transported to the picking position by the turntable 37, further stabilizing the feeding rhythm and meeting the diverse needs of customers for the feeding system.

[0081] Compared with the prior art, the advantages of the present invention are: modular design, compact and coordinated structure, stable operation and high work efficiency, and relaxed size ratio restrictions on the rods 50 with heads. By visually judging whether the posture of the rods 50 with heads in the linear track 11 is correct, those that do not meet the picking requirements of the support holes 41 will be blown off the linear track 11, and there is a high probability that the rods 50 with heads enter the support holes 41 in a posture that meets the picking requirements of the support holes 41, and are thereby transported to the picking position by the turntable 37, thereby meeting customers' needs for the transportation of various rods 50 with heads.

[0082] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any modifications may be made within the scope of protection of the present invention.
