Description

Technical Field

[0001] The utility model relates to a spring screw feeding device. Background Art

[0002] In the existing design of the spring screw feeding device, when the feeding mechanism receives the spring screw, the spring screw is in an upright position, that is, the spring screw is carried on the feeding mechanism with the bottom end of its spring away from the nut. In this way, due to the height error of the spring (for example, up to about 10%), the centers of the circles of the spring are not on the same central axis, that is, the axis of the spring is curved, which makes it easy for the spring screw to step on empty space when it is fed to the feeding mechanism. Furthermore, in the existing design, when the spring screw is fed to the electric screwdriver (also known as an electric screwdriver), there is a lack of a spring screw posture correction mechanism, and the adsorbed surface of the spring screw (for example, the end face of the nut end of the spring screw) cannot be horizontal, resulting in the electric screwdriver taking the material incorrectly during adsorption, affecting the use of the spring screw.

It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and drawings therein are essentially for illustrative purposes rather than for limiting the present invention.

[0050] like Figure 1 As shown, in one embodiment of the present invention, the spring screw feeding device provided by the present invention includes a feeding mechanism 100, a material dividing mechanism 200, a conveying mechanism 300 and a material receiving mechanism 400.

The structure, connection mode and functional relationship of each main component of the spring screw feeding device proposed by the utility model will be described in detail below in conjunction with the above drawings.

[0051] like Figures 1 to 9As shown, in one embodiment of the present invention, the feeding mechanism 100 is used to convey the spring screw A in the horizontal direction and to carry the nut end a1 of the spring screw A, so that the spring screw A is placed in the feeding mechanism 100 in an inverted state. The so-called inverted state can be understood as the nut end a1 of the spring screw A facing downward and the stud end a2 facing upward. Since the spring a3 of the spring screw A is connected to the nut and is located on the side of the nut facing the stud, when the spring screw A is in an inverted state, it is placed with the end face of the stud end a2, which is conducive to maintaining a stable placement state. The dividing mechanism 200 is arranged at the dividing place 101 of the feeding mechanism 100, and the dividing mechanism 200 is used to receive the spring screw A removed from the dividing place 101. The conveying mechanism 300 is arranged between the material distributing mechanism 200 and the material receiving mechanism 400. The conveying mechanism 300 is used to transmit the spring screw A of the material distributing mechanism 200 to the material receiving mechanism 400, and the conveying mechanism 300 can flip the spring screw A during the conveying process, so that the spring screw A is placed in the material receiving mechanism 400 in an upright state. The so-called upright state can be understood as the nut end a1 of the spring screw A facing upward and the stud end a2 facing downward, thereby facilitating the downstream equipment such as the electric screwdriver to take the material. Through the above structural design, the utility model can realize the spring screw A to be fed to the material distributing mechanism 200 in an inverted state, avoiding the spring screw A from stepping into the air in the material distributing mechanism 200, which is conducive to improving the posture stability of the spring screw A in the material distributing mechanism 200. At the same time, the utility model uses the conveying mechanism 300 to realize the flipping of the spring screw A, thereby ensuring that the material receiving mechanism 400 can receive the spring screw A in an upright state, which is convenient for taking components such as the electric screwdriver.

[0052] like Figure 2 As shown, in one embodiment of the present invention, the feeding mechanism 100 may include a circular vibrating screen 110 and a linear vibrating screen 120. The circular vibrating screen 110 and the linear vibrating screen 120 are respectively used to carry and convey the spring screws A in the horizontal direction. The feeding end of the linear vibrating screen 120 is connected to the discharge of the circular vibrating screen 110, and the discharge end of the linear vibrating screen 120 is the material separation point 101 of the feeding mechanism 100. Through the above structural design, the present invention can use the circular vibrating screen 110 to sort the spring screws A, and can use the linear vibrating screen 120 to align the spring screws A, thereby making the spring screws A after sorting and aligning stably move to the discharge point, so as to facilitate the separation of single particles from the entire column and convey them to the dividing mechanism 200.

[0053] like Figures 2 to 6As shown, in one embodiment of the utility model, the material distribution mechanism 200 may include a material distribution block 210 and a transverse driving mechanism 220. The material distribution block 210 is arranged at the material distribution location 101 of the feeding mechanism 100, and the material distribution block 210 is provided with a material slot 211, and the material distribution block 210 is used to receive and accommodate the spring screw A removed from the material distribution location 101 through the material slot 211. The notch of the material slot 211 is located on the top surface of the material distribution block 210, and one side of the material slot 211 is opened on the side of the material distribution block 210 facing the material distribution location 101 to form a feeding port. The transverse driving mechanism 220 is used to drive the material distribution block 210 to move in the horizontal direction, so that the material distribution block 210 moves between the first position and the second position. On this basis, when the dividing block 210 is located at the first position, the feed port of the dividing block 210 corresponds to the position of the dividing position 101 of the feeding mechanism 100, and when the dividing block 210 is located at the second position, the slot of the material slot 211 corresponds to the position of the conveying mechanism 300 (for example Figure 6 Through the above structural design, the utility model utilizes the translation of the material dividing block 210 to realize the movement of materials between different workstations, and is beneficial to the arrangement of the feeding mechanism 100 and the conveying mechanism 300, avoiding the problem of multiple components being concentrated in a small space.

[0054] like Figure 5 and Figure 6 As shown, based on the structural design that the material distribution mechanism 200 includes a material distribution block 210 and the material distribution block 210 is provided with a material slot 211, in one embodiment of the present utility model, a chamfer structure 212 may be provided at the connection between the feed port of the material slot 211 and the side of the material distribution block 210, such as but not limited to an inclined chamfer, an arc chamfer, etc. Through the above structural design, the present utility model can use the chamfer structure 212 to provide a guiding function, so that the spring screw A can enter the material slot 211 more smoothly, and can alleviate the transmission jam caused by the position error.

[0055] like Figure 3 and Figure 4As shown, based on the structural design that the material distribution mechanism 200 includes a material distribution block 210 and the material distribution block 210 is provided with a material trough 211, in one embodiment of the utility model, the material distribution mechanism 200 may also include a feeding in place detection unit 230, and the feeding in place detection unit 230 is used to detect whether the spring screw A in the material trough 211 is in place. Among them, the feeding in place detection unit 230 can be connected to a control system, such as a whole machine control system of a spring screw feeding device, and the control system can control the transverse drive mechanism 220 to drive the material distribution block 210 from the first position to the second position when receiving the in place signal of the feeding in place detection unit 230. In addition, the control system can also perform linkage control on the conveying mechanism 300 and the material receiving mechanism 400. Through the above-mentioned structural design, the utility model can realize the in place detection of the material distribution position and avoid the phenomenon of empty material transverse movement of the material distribution block 210.

[0056] Furthermore, in one embodiment of the present invention, the control system can delay a preset time before issuing a control instruction to the transverse drive mechanism 220 when receiving the arrival signal, thereby realizing the function of delaying transverse movement after the material is in place, thereby further avoiding the phenomenon of empty material transverse movement.

[0057] like Figure 3 and Figure 4 As shown, based on the structural design of the material distribution mechanism 200 including the material feeding detection unit 230, in one embodiment of the present utility model, the material feeding detection unit 230 can be a fiber optic detector. For example, the fiber optic detector can include two detection units, and the two detection units can be arranged above and below the material distribution block 210, respectively.

[0058] Based on the structural design that the material distribution mechanism 200 includes the transverse driving mechanism 220, in one embodiment of the present utility model, the transverse driving mechanism 220 can be a linear cylinder. In some embodiments, the transverse driving mechanism 220 can use other driving components, such as but not limited to a linear motor, etc., and is not limited to this embodiment.

[0059] like Figure 7 and Figure 8 As shown, in one embodiment of the present invention, the conveying mechanism 300 may include two extraction units. The two extraction units are arranged in a horizontal direction and are located above the material dispensing mechanism 200 and the material receiving mechanism 400, respectively. The extraction unit may include a rotating block 310 and an extraction member. The rotating block 310 is rotatably disposed on a bracket (e.g. Figure 7The first state and the second state are respectively provided on the third bracket 350 shown in the figure, and the corresponding rotation axis of the rotation action is in the horizontal direction, and the rotating block 310 is driven by the rotating driving mechanism 330. The extracting member is arranged on the rotating block 310 in a translational manner and is driven by the translation driving mechanism 340. Accordingly, the rotating block 310 can be switched between the first state and the second state through rotation. When the rotating block 310 is in the first state, the translation direction of the extracting member is in the vertical direction, and the extracting member is used to extract or place the spring screw A. When the rotating block 310 is in the second state, the translation direction of the extracting member is in the horizontal direction. When the rotating blocks 310 of the two extracting units are both in the second state, the spring screw A can be transferred between the extracting members of the two extracting units. Among them, during the transfer process between the two extracting members, one of the extracting members can perform a translational action, or the two extracting members can perform a coordinated translational action at the same time.

[0060] It should be noted that in Figure 1 In the illustrated embodiment, the spacing arrangement direction of the two extraction units (i.e., the relative arrangement direction of the material distribution mechanism 200 and the material receiving mechanism 400) and the lateral movement direction of the material distribution block 210 have an angle that is not 0 and 180°, and can further be 90°. Through the above structural design, the utility model is conducive to reducing the overall size of the equipment and reducing space occupation. In some embodiments, the spacing arrangement direction of the two extraction units and the lateral movement direction of the material distribution block 210 can also be parallel to each other, which is not limited to this embodiment.

[0061] like Figure 8 As shown, based on the structural design that the conveying mechanism 300 includes an extraction unit and the extraction unit includes an extraction member, in one embodiment of the present invention, the extraction member can be a vacuum nozzle. In some embodiments, the extraction member can also adopt other extraction structures, such as but not limited to a magnetic suction cup, etc., and is not limited to this embodiment.

[0062] like Figure 8As shown, based on the structural design that the extraction member of the conveying mechanism 300 is a vacuum suction nozzle, in one embodiment of the present utility model, for the convenience of description and understanding, the following defines two extraction units as a first unit 301 and a second unit 302, the first unit 301 is the extraction unit located above the material distribution mechanism 200, and the vacuum suction nozzle of the first unit 301 is the first suction nozzle 321, the second unit 302 is the extraction unit located above the material receiving mechanism 400, and its vacuum suction nozzle is the second suction nozzle 322. On this basis, the suction port 3211 at the end of the first suction nozzle 321 matches the shape of the stud end a2 of the spring screw A. The end of the second suction nozzle 322 is provided with a receiving groove 3221, the receiving groove 3221 matches the shape of the nut end a1 of the spring screw A, the receiving groove 3221 is used to accommodate the nut end a1 of the spring screw A, and the suction port 3222 of the second suction nozzle 322 is arranged at the bottom of the receiving groove 3221. Through the above structural design, the utility model utilizes the differentiated design of the air inlets of the two vacuum suction nozzles to adapt to the adsorption and extraction of different positions of the spring screw A, which is beneficial to the stability of the posture of the spring screw A during the transmission process.

[0063] Based on the structural design of the transmission mechanism 300 including the rotation drive mechanism 330, in one embodiment of the present utility model, the rotation drive mechanism 330 can be a rotation cylinder. In some embodiments, the transverse rotation drive mechanism 330 can use other driving components, such as but not limited to a rotation motor, etc., and is not limited to this embodiment.

[0064] Based on the structural design of the transmission mechanism 300 including the translation drive mechanism 340, in one embodiment of the present invention, the translation drive mechanism 340 can be a linear cylinder. In some embodiments, the translation drive mechanism 340 can use other drive components, such as but not limited to a linear motor, etc., and is not limited to this embodiment.

[0065] like Fig. 9As shown, in one embodiment of the utility model, the material receiving mechanism 400 may include a dividing plate 410 and a driving motor 420. A plurality of positioning hollow shafts 411 are arranged on the dividing plate 410. The plurality of positioning hollow shafts 411 are arranged at intervals along a circular path. The internal cavity of the positioning hollow shaft 411 opens at its top to form an orifice, and the positioning hollow shaft 411 can pass through the orifice for the stud end a2 of the spring screw A to pass through and be accommodated in the internal cavity. The driving motor 420 is used to drive the dividing plate 410 to rotate, and the driving motor 420 drives the dividing plate 410 to rotate a preset angle each time, thereby making the plurality of positioning hollow shafts 411 successively located below the conveying mechanism 300 (for example, the second suction nozzle 322). Through the above-mentioned structural design, the utility model can utilize the positioning hollow shaft 411 to realize that the spring screw A maintains a stable posture (for example, the vertical posture of the stud) in the upright state, avoid the problem of the spring screw A standing in an incorrect posture, and thereby maintain the horizontal state of the end face of the nut end a1, thereby facilitating the suction of the electric screw. In addition, the utility model utilizes the positioning hollow shaft 411 to place and position the spring screw A, which can facilitate observation of whether the material is defective and whether the material has been taken away.

[0066] like Figure 1 As shown, in one embodiment of the present invention, the various components of the spring screw feeding device can be arranged together on a base 500, thereby improving the integrity of the device and facilitating overall transportation and installation.

[0067] like Figure 1 and Figure 2 As shown, based on the structural design of the spring screw feeding device including a base 500, in one embodiment of the utility model, the circular vibrating screen 110 can be set on the base 500 through the mounting seat 130, the linear vibrating screen 120 can be set on the base 500 through the first bracket 140, the dividing mechanism 200 can be set on the base 500 through the second bracket 240, the conveying mechanism 300 can be set on the base 500 through the third bracket 350, and the receiving mechanism 400 can be set on the base 500 through the fourth bracket 430.

[0068] Based on the above detailed description of the spring screw feeding device proposed in the utility model, the following Figures 10 to 15 , the working process of the spring screw feeding device proposed in the utility model is described. Among them, Figures 10 to 15 The partially enlarged schematic diagrams of the spring screw feeding device in several different action steps are representatively shown.

[0069] After being sorted by the circular vibrating screen 110 and aligned by the linear vibrating screen 120, the spring screws A are transferred to the material slot 211 of the material dividing block 210 via the material dividing portion 101 of the material receiving mechanism 400 (eg, Fig.10The feeding in-place detection unit 230 detects the in-place position, and the control system controls the transverse driving mechanism 220 to move according to the in-place signal, driving the material dividing block 210 to transversely move from the first position to the second position (as shown in FIG. Fig.11 The control system controls the rotation drive mechanism 330 of the first unit 301 to drive the rotating block 310 to rotate to the first state, at which time the first suction nozzle 321 is located directly above the material slot 211. The control system controls the translation drive mechanism 340 of the first unit 301 to drive the first suction nozzle 321 to descend and suck the spring screw A in the material slot 211 (as shown). Fig.12 As shown in FIG. 1 , since the spring screw A is in an inverted state, the first suction nozzle 321 specifically sucks the stud end a2 of the spring screw A. The control system controls the translation drive mechanism 340 of the first unit 301 to move, driving the first suction nozzle 321 to rise and return to its original position (as shown in FIG. 1 ). Fig.13 The control system controls the rotation drive mechanism 330 of the two extraction units to drive the two rotating blocks 310 to rotate to the second state, at which time the first suction nozzle 321 is opposite to the second suction nozzle 322 (as shown in FIG. Fig.14 As shown), that is, the second suction nozzle 322 corresponds to the nut end a1 of the spring screw A. The control system controls the translation drive mechanism 340 of at least one of the two extraction units to move, so that the second suction nozzle 322 moves toward the spring screw A and sucks, and the first suction nozzle 321 stops sucking, thereby completing the transfer of the spring screw A between the two extraction units. The control system controls the rotation drive mechanism 330 of the second unit 302 to drive the rotating block 310 to rotate to the first state, thereby completing the posture rotation of the spring screw A (from inverted rotation to upright rotation). At this time, the second suction nozzle 322 and the spring screw A sucked by it are located directly above a positioning hollow shaft 411 of the dividing plate 410 (as shown in FIG. 1 ). Fig.15 As shown). The control system controls the translation drive mechanism 340 of the second unit 302 to move, driving the second suction nozzle 322 to descend so that the stud end a2 of the spring screw A enters the positioning hollow shaft 411, and the second suction nozzle 322 stops sucking, and the spring screw A in the upright state is carried and positioned by the positioning hollow shaft 411.
