Description

TECHNICAL FIELD

[0001] The present application relates to the field of assembling mechanical equipment, in particular to a material distributing mechanism. BACKGROUND

[0002] Most products need to use fasteners in the process of processing and assembling. From separating fasteners to installing fasteners, if the process is completed by manual work, the cost is high, the efficiency is low, and it is difficult to adapt to the rhythm of batch production. If at least part of the above actions is completed by mechanical equipment, the work efficiency can be improved.

[0003] Taking a screw as an example, the prior art mentions a beak type locking mechanism scheme, which supplies the screw to a fixed position through a screw supply pipe, and then lowers the electric screwdriver to lock. However, in actual application, the screw is easy to be inclined, which makes it difficult for the electric screwdriver to align the hole, thereby causing the electric screwdriver to be severely worn.

[0004] The prior art also mentions a scheme, in which the screw feeder is placed in a fixed position, the electric screwdriver moves to take the material, then moves to the locking position, and finally screws the screw on the product. However, this scheme causes the electric screwdriver to move a long distance, which also reduces the work efficiency. SUMMARY

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] The following refers to Figures 1-5 The material distribution mechanism 100 according to the embodiments of the present application is described.

[0035] As Figures 1-2As shown, the material distributing mechanism 100 according to the embodiment of the present application comprises a base 10, a conduit 30, a feeding member 40 and a driving member 50.

[0036] As shown, the conduit 30 has a discharging end 31 for outputting the fastener 20, the discharging end 31 is fixed relative to the base 10, and the air pressure value of the conduit 30 is 0.2-0.6 Mpa. Figure 3 As shown, the feeding member 40 is movably arranged on the base 10, and the feeding member 40 has a first position and a second position on the base 10. Figures 2-3 As shown, the feeding member 40 is movably arranged on the base 10, and the feeding member 40 has a first position and a second position on the base 10.

[0037] Wherein, when the feeding member 40 is at the first position, the distance m between the positioning hole 41 and the discharging end 31 is between 1-6 mm.

[0038] That is, the material distributing mechanism 100 according to the embodiment of the present application is supplied by the conduit 30, the feeding member 40 receives the material, and the driving member 50 drives the feeding member 40 to move to complete the transfer of the fastener 20.

[0039] Here, the conduit 30 is used for supplying the material, and the fastener 20 can slide along the conduit 30 under the driving of the acting force (such as gravity, wind force, etc.). The conduit 30 can save the complex transmission mechanical device for conveying the fastener 20. For example, when the fastener 20 needs to be reversed during conveying, the conduit 30 can be only arranged as an elbow pipe to achieve the reversing, while the general transmission mechanical device can need two or even more degrees of freedom. The conduit 30 has a relatively simple conveying structure and occupies less space compared with the general transmission mechanical device. Moreover, the general transmission mechanical device is limited in conveying distance and conveying direction due to the structure, and is easy to interfere with the surrounding parts. After the general transmission mechanical device is replaced by the conduit 30, the selection space of the conveying distance and the conveying direction is large, and it is relatively easy to adjust according to the actual needs, which is conducive to the simplification and compact layout of the material distributing mechanism 100.

[0040] Optionally, the air pressure inside the conduit 30 is 0.2-0.6 MPa. Preferably, the air pressure inside the conduit 30 is 0.4-0.5 MPa. When the conduit 30 drives the fastener 20 by positive pressure blowing air, the air pressure inside the conduit 30 should not be too high or too low, preferably 0.2-0.6 MPa. When the air pressure inside the conduit 30 is greater than 0.6 MPa, it will result in excessive air pressure blowing the fastener 20, thereby damaging the surface plating and external threads of the fastener 20. When the air pressure inside the conduit 30 is less than 0.2 MPa, it will result in insufficient air pressure blowing the fastener 20, thereby preventing the fastener 20 from reaching the designated position or causing backflow within the conduit 30.

[0041] By providing a positioning hole 41 on the feeding component 40, when the feeding component 40 is in the first position, the positioning hole 41 is aligned with the discharge end 31 of the guide tube 30. This allows the feeding component 40 to automatically position the fastener 20 during the material receiving process. If a conventional conveying mechanism were used, inserting the fastener 20 into the positioning hole 41 would require higher control precision. However, by providing a positioning hole 41 on the feeding component 40, the guide tube 30 automatically positions the fastener 20 when it is conveyed to the positioning hole 41, saving time and reducing the requirement for control precision.

[0042] Among them, such as Figure 3 As shown, when the feeding part 40 is in the first position, the distance m between the positioning hole 41 and the discharge end 31 is 1-6 mm. Optionally, the distance between the positioning hole 41 and the discharge end 31 can also be 1.5-5.5 mm or 2-4 mm. During the process of the fastener 20 falling into the positioning hole 41, if the distance m between the positioning hole 41 and the discharge end 31 is greater than 6 mm, the fastener 20 will not be able to fall accurately into the positioning hole 41 and may get stuck between the positioning hole 41 and the discharge end 31, which will cause damage to the material distribution mechanism 100. When the distance m is less than 1.5 mm, the distance between the positioning hole 41 and the discharge end 31 will be too small, which is not conducive to the subsequent maintenance of the material distribution mechanism 100. Furthermore, after the material distribution mechanism 100 has been running for a long time, some metal shavings and debris may accumulate in the positioning hole 41, and a distance m that is too small is not conducive to cleaning the positioning hole.

[0043] The loading component 40 is moved from the first position to the second position by the driving component 50, and the fastener 20, which is positioned at the positioning hole 41, moves accordingly. Since the fastener 20 fits into the positioning hole 41, it moves smoothly with the loading component 40 and is less likely to fall off. Furthermore, when the loading component 40 reaches the second position and the fastener 20 is also delivered into place, the fastener 20 remains in its positioned state and is less prone to tilting. This reduces the risk of wear and tear on installation tools when the fastener 20 is subsequently removed or installed.

[0044] In the scheme of the present application, the arrangement of the driving member 50 and the feeding member 40 not only positions the fastener 20 before installation, but also moves the position of the fastener 20. Thus, when the installation tool takes the fastener 20, the positioning difficulty of the installation tool is greatly reduced, and the installation tool does not need to move to the position of the fastener 20. After the movement time of the installation tool is reduced, the installation efficiency of the installation tool can be greatly improved.

[0045] Even when the installation tool takes out the fastener 20, the driving member 50 can drive the feeding member 40 to return to the first position. Thus, after the feeding member 40 avoids the position, the product to be installed can be placed at the position, and the installation tool directly installs at the position. Thus, the movement time of the installation tool is less, and the installation efficiency is higher.

[0046] In the scheme of the present application, the fastener 20 is not limited to a screw, a nut, or even a rivet.

[0047] In some specific embodiments, when the fastener 20 is a screw, the installation tool can be an electric screwdriver. After the electric screwdriver takes out the screw, the electric screwdriver can move to a specified position to complete the locking action of the screw. When the fastener 20 is a nut, the installation tool can be an automatic nut locking machine. After the automatic nut locking machine takes out the nut, the automatic nut locking machine automatically tightens the nut on the product.

[0048] In some specific embodiments, when the fastener 20 is a rivet, the installation tool can be a rivet gun. After the rivet gun takes out the rivet, the rivet gun can move to a specified position to shoot the rivet on the product.

[0049] When the positioning hole 41 of the feeding member 40 positions the fastener 20, the fastener 20 can all fall into the positioning hole 41, or only part of the fastener 20 can fall into the positioning hole 41, which is not limited here.

[0050] In some embodiments, the guide pipe 20 can use gravity to transport the fastener 20. The guide pipe 20 extends in the up-down direction, and the feeding member 40 is located below the guide pipe 20. Since the gravity is derived from the fastener 20 itself, the transportation cost is low. In this transportation mode, the guide pipe 20 can be a straight pipe or a pipe with a certain curvature, but the feeding end of the guide pipe 20 is higher than the discharging end 31.

[0051] In other embodiments, the guide pipe 20 can use fluid pressure to transport the fastener 20, such as a wind pipe or a water pipe connected to the guide pipe 20, to drive the fastener 20 to flow by wind pressure or water flow pressure. When fluid pressure is used, the guide pipe 20 can be a straight pipe or a curved pipe.

[0052] Specifically, when the fastener 20 is in the conduit 30, the two are generally consistent in axial extension direction. More specifically, the conduit 30 can be a circular tube, and the inner diameter of the circular tube is greater than the maximum circular diameter of the fastener 20, so as to ensure the smoothness of conveying the fastener 20. Of course, the present application is not limited thereto, for example, the conduit 30 can also be a square tube or a tube with other cross-sectional shapes.

[0053] In some embodiments, as shown in Figure 1 The discharge end 31 is located above the positioning hole 41, and when the fastener 20 slides out of the conduit 30, it directly slides into the positioning hole 41 by gravity, thereby achieving positioning of the fastener 20. In this way, the fastener 20 can be smoothly retained on the feeding member 40 by gravity. When the feeding member 40 is movable, the feeding member 40 can be translated, so that the fastener 20 is still smoothly retained at the positioning hole 41 during movement.

[0054] Specifically, the discharge end 31 of the conduit 30 is vertically downwardly extended, and the axis of the positioning hole 41 is vertically arranged, so that the fastener 20 is vertically downwardly guided by the conduit 30, which is consistent with the direction of gravity, thereby reducing the shaking of the fastener 20 when it is discharged.

[0055] In other examples, the axis of the positioning hole 41 on the feeding member 40 can also have a certain angle relative to the vertical line, and the discharge end 31 has a certain angle relative to the vertical line.

[0056] In some schemes, the feeding member 40 can be provided with a magnetic member (such as a magnet), and when the fastener 20 is guided or shot by the conduit 30 to the positioning hole 41, the fastener 20 is also attracted to the positioning hole 41 by the magnetic force until it is taken out by the installation tool.

[0057] Optionally, the installation tool can use suction force (such as magnetic suction or negative pressure suction) to suck the fastener 20 out of the positioning hole 41 when taking out the fastener 20 from the feeding member 40. In some schemes, the installation tool is provided with a clamp to clamp the fastener 20 and then move to take out the fastener 20.

[0058] As shown in Figure 1 and Figure 3 In some embodiments, the base 10 includes a base plate 11, a tube fixing plate 12, and a connecting plate 13, and the driving member 50 and the feeding member 40 are both mounted on the base plate 11. The tube fixing plate 12 is arranged on one side of the base plate 11 in a spaced manner, the conduit 30 is mounted on the tube fixing plate 12, and the connecting plate 13 connects the base plate 11 and the tube fixing plate 12.

[0059] The driving member 50 and the feeding member 40 are installed on the base plate 11, and the pipe fixing plate 12 is also connected to the base plate 11 through the connecting plate 13, so that the relative positions of the above-mentioned components are fixed with the base 10, and the stability of the whole distribution mechanism 100 can be improved. Moreover, the plate body is connected, the contact area is large, the connection is stable and reliable. After the pipe fixing plate 12 is connected to the pipe 30, the shaking of the outlet end 31 of the pipe 30 is reduced, and the position accuracy of the fastener 20 on the feeding plate 40 is improved.

[0060] The pipe fixing plate 12 is arranged on one side of the base plate 11 and is spaced apart from the base plate 11, so that the gap between the base plate 11 and the pipe fixing plate 12 can provide accommodation space for the feeding member 40, and the positioning hole 41 of the outlet end 31 of the pipe 30 and the feeding member 40 are correspondingly arranged.

[0061] Here, the connection mode of the driving member 50, the feeding member 40 and the connecting plate 13 with the base plate 11 is not limited, and the connection of any one of the above-mentioned with the base plate 11 can be screwed, buckled, or even welded.

[0062] For example, the driving member 50, the feeding member 40 and the connecting plate 13 can be fixed on the base 10 by using screws, so that the components can be disassembled, the components can be replaced conveniently, and the expansibility of the distribution mechanism 100 is improved.

[0063] For another example, a plurality of inverted trapezoidal grooves can be arranged on the base 10, and trapezoidal protrusions corresponding to the grooves of the base 10 are arranged on the bottom of the driving member 50, the feeding member 40 and the connecting plate 13. The components are inserted and pulled out to realize the replacement of the components, so that the expansibility of the distribution mechanism 100 is improved.

[0064] In some specific embodiments, as shown in Figure 1 The pipe fixing plate 12 is arranged on one side of the base plate 11 and is spaced apart from the base plate 11, so that the gap between the base plate 11 and the pipe fixing plate 12 can provide accommodation space for the feeding member 40, and the positioning hole 41 of the outlet end 31 of the pipe 30 and the feeding member 40 are correspondingly arranged.

[0065] Optionally, as shown in Figure 3 The outlet end 31 passes through the pipe fixing hole 121 and extends to the side of the pipe fixing plate 12 close to the base plate 11. In this way, the outlet end 31 and the positioning hole 41 of the feeding member 40 are closer, so that the fastener 20 is more accurately dropped into the positioning hole 41 when it is output from the outlet end 31, the accuracy of the distribution of the distribution mechanism 100 is improved, and the working efficiency of the distribution mechanism 100 is improved.

[0066] Further optionally, as shown in Figure 3As shown, the discharge end 31 of the conduit 30 is not a flat end, meaning the opening of the conduit 30 facing the positioning hole 41 is not flat. Optionally, the cross-section of the discharge end 31 of the conduit 30 is an oblique elliptical arc or an oblique circular arc. It is understandable that if the discharge end 31 of the conduit 30 is a flat end, the surrounding air pressure of the fastener 20 changes drastically the instant it is discharged from the discharge end 31, affecting the state of the fastener 20. By setting the discharge end 31 of the conduit 30 to be a non-flat end, when the fastener 20 leaves the conduit 30, there is a buffer time for the change in air pressure around the fastener 20, which helps the fastener 20 remain stable at the moment of discharge.

[0067] Optionally, the conduit 30 has an angled opening at the discharge end 31, and the angle between the conduit 30 at the discharge end 31 and the horizontal plane is between 5 and 35 degrees. Preferably, the angle between the conduit 30 at the discharge end 31 and the horizontal plane is between 15 and 25 degrees. When the conduit 30 blows the fastener 20 into the positioning hole 41, it allows the gas inside the conduit 30 to be discharged more quickly, preventing any impact on the fit between the fastener 20 and the positioning hole 41.

[0068] Optionally, the discharge end 31 is inserted into the tube fixing hole 121 by an interference fit. This makes the discharge end 31 more securely fixed in the tube fixing hole 121, eliminating the need for other connecting parts.

[0069] like Figures 2-4 As shown, the tube fixing plate 12 is further arranged parallel above the substrate 11, and the feeding component 40 is located above the substrate 11 and below the tube fixing plate 12. That is, the tube fixing plate 12 is parallel to the substrate 11, the feeding component 40 is sandwiched between the substrate 11 and the tube fixing plate 12, and the tube fixing plate 12, the feeding component 40 and the substrate 11 are parallel to each other. In this way, the discharge end 31 fixed on the tube fixing plate 12 is perpendicular to the feeding component 40, which can ensure that the fastener 20 output from the discharge end 31 falls vertically into the positioning hole 41, preventing the fastener 20 from being skewed.

[0070] Optionally, the feeding component 40 has multiple positioning holes 41 and multiple tube fixing holes 121. Correspondingly, there are also multiple guide tubes 30. The three are set in a one-to-one correspondence. In this way, the feeding hole 40 can hold multiple fasteners 20.

[0071] like Figure 2As shown, in some embodiments, the feeding piece 40 includes a first feeding section 401 and a second feeding section 402, the first feeding section 401 is arranged along the moving direction of the feeding piece 40, the first feeding section 401 is slidingly connected to the base plate 11, the second feeding section 402 is bent from one end of the first feeding section 401 and connected to the driving piece 50, and the positioning hole 41 is arranged on the second feeding section 402. The pipe fixing plate 12 includes a first pipe fixing section 122 and a second pipe fixing section 123, the first pipe fixing section 122 is arranged in parallel with the first feeding section 401, the second pipe fixing section 123 is arranged in parallel with the second feeding section 402, and the conduit 30 is connected to the second pipe fixing section 123. The first feeding section 401 is slidingly connected to the base plate 11, so that the feeding piece 40 can move more stably on the base plate 11, and according to the arrangement of the sliding part, the feeding piece 40 can move between the first position and the second position, ensuring that the position of each movement is the same, which can increase the accuracy of the position of the fastener 20, facilitate the suction of the fastener 20 in the subsequent process, and increase the production efficiency.

[0072] Optionally, a plurality of conduits 30 can be arranged on the second pipe fixing section 123, and correspondingly, a plurality of pipe fixing holes 121 are arranged on the second pipe fixing section 123, so that different specifications of fasteners 20 can be conveyed in different conduits 30, thereby increasing the expansibility of the distribution mechanism 100.

[0073] Further, the feeding piece 40 can have a third position, when the number of conduits 30 is two, the third position of the feeding piece 40 is below the position of the discharge end 31 corresponding to the second conduit 30, so that the feeding piece 40 can realize the receiving of the fastener 20 conveyed in the second conduit 30 when the feeding piece 40 is in the third position. Then the installation tool sucks the fastener 20 again when the feeding piece 40 moves to the second position. This arrangement can increase the expansibility of the distribution mechanism 100 and increase the production efficiency.

[0074] As shown, Figure 5 Further, the base plate 11 includes a mounting section 111, a flat connecting section 112, and an extension section 113, the driving piece 50 and the feeding piece 40 are arranged side by side on the mounting section 111. One end of the flat connecting section 112 is connected to the mounting section 111 and is located on the side of the feeding piece 40 away from the driving piece 50. The extension section 113 is connected to the other end of the flat connecting section 112 and is arranged along the moving direction of the feeding piece 40. Among them, the flat connecting section 112, the mounting section 111 and the extension section 113 form an angle groove 114, and the vertical projection of the positioning hole 41 on the base plate 11 is within the angle groove 114 in the moving range of the feeding piece 40.

[0075] The mounting section 111 of the substrate 11 provides a mounting position for the driving member 50 and the feeding member 40, and the extension section 113 provides a mounting position for fixing the substrate 11 to a mounting tool. If the subsequent fastener 20 needs to be detected and positioned, the extension section 113 provides a mounting position therefor.

[0076] The angle groove 114 formed between the abutment section 112, the mounting section 111 and the extension section 113 can provide a moving space for the feeding member 40 without blocking the fastener 20 on the feeding member 40. Even the product to be mounted can be placed below the angle groove 114, and the mounting tool can directly mount the fastener on the product at the angle groove 114 after sucking the fastener, and the distance to be moved by the mounting tool is shorter.

[0077] As shown in Figure 2 some embodiments, the positioning hole 41 includes an axial large hole portion 411 and a small hole portion 412, and the large hole portion 411 is located on the side of the small hole portion 412 adjacent to the discharge end 31 of the conduit 30. The positioning hole 41 with such a structure can adapt to the positioning of various fasteners 20. For example, when the fastener 20 is a screw, bolt or rivet, the fastener 20 has a head portion and a rod portion, the head portion of the fastener 20 can be fitted in the large hole portion 411, and the rod portion of the fastener 20 can be inserted into the small hole portion 412. In this way, the fastener 20 is less likely to fall off when the feeding member 40 moves. For another example, when the fastener 20 is a nut, the nut can fall into the large hole portion 411.

[0078] It should be noted that the shapes and sizes of the large hole portion 411 and the small hole portion 412 are not specifically limited herein, and can be determined according to the shapes and sizes of the fastener 20, or can both be round holes. When the conduit 30 is multiple and the specifications of the fasteners 20 to be conveyed are different, the sizes of the large hole portion 411 and the small hole portion 412 can be determined to be such that the larger fastener 20 can be fitted and the smaller fastener 20 can be ensured not to fall off, and can be adjusted according to the actual sizes of the fastener 20.

[0079] In some embodiments, as shown in Figure 4 the feeding member 40 is connected to the base 10 through a guide rail-sliding block structure 60. In this way, the stability of the feeding member 40 when moving on the base 10 can be increased, so as to improve the positioning accuracy of the fastener 20. Figure 4 In some examples, the guide rail 61 of the guide rail-sliding block structure 60 is arranged on the base 10, and the sliding block 62 is arranged on the feeding member 40. In some other examples, the guide rail 61 is arranged on the feeding member 40, and the sliding block 62 is arranged on the base 10.

[0080] It should be noted that the connection between the feeding member 40 and the base 10 can also be other connection modes, which are not specifically limited here. For example, a protrusion can be directly machined on the feeding member 40, and a groove is machined on the base 10, and the protrusion cooperates in the groove to also play a guiding role.

[0081] In the scheme of the present application, when the feeding member 40 moves between the first position and the second position, the feeding member 40 can move along a straight line or along an arc, which is not limited here. In some schemes, the feeding member 40 can even rotate, so that the angle of the feeding member 40 relative to the horizontal plane at the first position is not equal to the angle of the feeding member 40 relative to the horizontal plane at the second position, which has stronger adaptability.

[0082] Optionally, the driving member 50 is a pneumatic cylinder. By using the pneumatic cylinder, the working medium is air, which is relatively easy to obtain, and after use, it is directly discharged to the atmosphere, which is convenient to handle, and can reduce production cost.

[0083] In other embodiments, the driving member 50 can also be a hydraulic cylinder, or a linear motor, etc. The driving member 50 can also be a rotary motor, and the motor shaft of the rotary motor is connected to the feeding member 40 through a threaded screw structure to also drive the feeding member 40 to move directly.

[0084] Optionally, the pressure of the driving member 50 is 1-4Kgf, and the speed is 60-140mm / s. Preferably, the pressure of the driving member 50 is 2-3Kgf, and the speed is 70-130mm / s or 80-120mm / s. When the driving member 50 drives the feeding member 40 to move horizontally between the first position and the second position, if the pressure is greater than 4Kgf and the speed is greater than 140mm / s, the fastener 20 will jump or jump out of the positioning hole 41 when being transported to the second position. If the pressure is less than 1Kgf and the speed is less than 60mm / s, the working efficiency of the distributing mechanism is too low, which will increase the production cost.

[0085] In the present application, the connection mode between the driving member 50 and the feeding member 40 is not specifically limited, and the connection mode between the driving member 50 and the feeding member 40 can include threaded connection, welding, when the driving member 50 and the feeding member 40 are connected through threaded connection, the structure between them is detachable, which can be replaced when different specifications of the feeding member 40 or the driving member 50 are needed, increasing the expandability of the distributing mechanism 100.

[0086] In Figures 1-2In the specific embodiment shown, when the screw is supplied by the conduit 30, the feeding member 40 can be driven by the driving member 50 to the first position, the screw is caught by the feeding member 40 and directly falls at the positioning hole 41, so that the screw is positioned and is not easy to be inclined. Then the driving member 50 drives the feeding member 40 to the second position, the screw can be directly sucked and locked by the locking mechanism, the moving time of the locking mechanism is short, and the efficiency of the automatic locking can be improved.
