[0042] Embodiment 1

[0043] See also Figures 1 to 5 As shown, the fastener assembly equipment provided in the present application includes a loading mechanism, a transfer mechanism 101 and a unloading mechanism 102 .

[0044] The loading mechanism includes a plurality of loading components, and the number of the loading components corresponds to the type of parts to be assembled (hereinafter referred to as parts). According to the assembly order of the parts to be assembled, a plurality of loading stations are sequentially arranged along the transportation path of the transfer mechanism 101, and the loading components are correspondingly installed at the loading stations, and are used to sequentially load the parts to the transfer mechanism 101 for assembly. The transfer mechanism 101 is used to sequentially transport the parts to be assembled at the first loading station to the remaining loading stations; the unloading mechanism 102 is located at the unloading station at the end of the transportation path of the transfer mechanism 101.

[0045] Specifically, if Figure 1 As shown, the fastener assembly equipment in the figure is used to assemble screws, spring washers and flat washers. The fastener assembly equipment needs to be provided with three corresponding loading assemblies to load screws, spring washers and flat washers respectively. Because when assembling screws, spring washers and flat washers, the spring washers need to be put on the rod of the screw first, and then the flat washers need to be put on the rod of the screw. Therefore, when the three loading assemblies load the parts loaded by each of them to the transfer mechanism 101, the loading assembly for loading screws is located at the head end of the transportation path of the transfer mechanism 101, so that the screws are first loaded onto the transfer mechanism 101; along the transportation direction of the transfer mechanism 101, the loading assembly for loading spring washers and the loading assembly for loading flat washers are sequentially arranged on the transportation path of the transfer mechanism 101, so that the spring washers and flat washers are sequentially loaded onto the transfer mechanism 101.

[0046] The loading assembly for loading screws is located at the first loading station, the loading assembly for loading spring washers is located at the second loading station, and the loading assembly for loading flat washers is located at the third loading station. The assembly process of the parts is as follows: first, at the first loading station, the loading assembly first loads the screws to the transfer mechanism 101; then, the transfer mechanism 101 first transports the screws to the second loading station, and the loading assembly at the second loading station loads the spring washers to the transfer mechanism 101, so that the spring washers can be sleeved on the screws of the transfer mechanism 101; finally, the transfer mechanism 101 transports the screws sleeved with spring washers to the third loading station, and the loading assembly at the third loading station loads the flat washers to the transfer mechanism 101, so that the flat washers can also be sleeved on the screws of the transfer mechanism 101.

[0047] When the assembly process of the parts is completed, the parts are assembled into a finished assembly product, and the transfer mechanism 101 needs to continue to transport the finished assembly product to the unloading station so that the finished assembly product can be collected and used for related equipment.

[0048] In an optional solution of this embodiment, the feeding assembly includes a vibration plate 103, a feeding screening device 104 and a feeding track 105. The vibration plate 103 can orderly arrange the multiple parts to be assembled corresponding to the feeding, and one end of the feeding track 105 is connected to the discharge port of the vibration plate 103, so that the parts arranged in a row enter the feeding track 105 in sequence. The other end of the feeding track 105 is connected to the transfer mechanism 101, and the parts to be assembled can be moved to the transfer mechanism 101 in sequence along the feeding track 105. The feeding screening device 104 is located on the transportation path of the feeding track 105 to screen the parts to be assembled so that the parts that do not meet the specifications are eliminated, and only the parts that meet the specifications can be fed to the transfer mechanism 101.

[0049] Specifically, Figure 2 and Figure 3 As shown, the feeding screening device 104 includes a screening component 106 and a material detection camera 107; the screening component 106 includes a material blocking member and a material pushing member; the material blocking member can be extended and retracted to block or release the parts to be assembled; the material detection camera 107 is specifically a visual inspection camera, the material inspection camera 107 is located above the feeding track 105 and is supported by a bracket, the material inspection camera 107 is used to detect whether the blocked parts to be assembled are qualified; the material pushing member can be extended and retracted to push unqualified parts to be assembled out of the feeding track 105.

[0050] In this embodiment, when the parts move along the feeding track 105, the parts can pass through the material detection camera 107 in sequence. When the parts move to the detection station, the screening component 106 arranged at the detection station can screen the parts. Specifically, the screening component 106 includes a material blocking member and a material pushing member, the material blocking member includes a material blocking cylinder and a baffle, and the material pushing member includes a material pushing cylinder and a push plate. The material blocking cylinder can drive the baffle to extend to block the parts moving to the detection station, and the parts stop moving at the detection station, so that the material detection camera 107 can shoot and identify the parts, thereby judging whether the parts are qualified; and the material blocking member can control the stepping speed of the parts, especially at the second and third feeding stations, the spring washers and flat washers must wait until the screws are moved into place before the materials can be loaded. If the parts are qualified, the material blocking cylinder drives the baffle to retract so that the parts continue to move forward. Only when the parts are unqualified, the push cylinder can drive the push plate to extend to push the unqualified parts out of the feeding track 105. In other cases, the push cylinder is in the state of driving the baffle to retract.

[0051] In an optional solution of this embodiment, among the multiple feeding assemblies, the feeding assembly used to feed the parts to be assembled in the first assembly sequence is the first feeding assembly 108 (see Figure 2 ), the remaining loading assembly is the second loading assembly 109 (see Figure 3). The feeding track 105 of the first feeding assembly 108 is flush with the transfer mechanism 101, so that the screws can be fed to the transfer mechanism 101 in sequence. Since the spring washers and flat washers to be assembled later need to be sleeved on the rod of the screw, the feeding track 105 of the second feeding assembly 109 is tilted, and the lower end of the feeding track 105 of the second feeding assembly 109 is opposite to the transfer mechanism 101. Under the action of gravity, at the second feeding station, the spring washers can fall and sleeve on the screw rod, and at the third feeding station, the flat washers can fall and sleeve on the screw rod with the spring washers, thereby completing the assembly of the parts.

[0052] Optionally, the discharge port of the vibration plate 103 of the second feeding assembly 109 is inclined at 60°, and the feeding track 105 of the second feeding assembly 109 is placed at an angle of 60°. When the parts enter the feeding track 105 from the discharge port of the vibration plate 103, the parts slide down along the discharge port of the vibration plate 103 due to gravity inertia. The connection between the discharge port of the vibration plate 103 of the second feeding assembly 109 and the feeding track 105 is provided with a photoelectric switch. When the photoelectric switch detects incoming materials, it can transmit a signal to the feeding screening device 104 to screen the parts.

[0053] Embodiment 2

[0054] The fastener assembly device in the second embodiment is an improvement on the above embodiment, and the technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0055] In an optional scheme of this embodiment, the transfer mechanism 101 includes a shifting device and a transfer rail 110; the discharge port of the loading mechanism is opposite to the transfer rail 110; the shifting device is installed on the side of the transfer rail 110, and the shifting device can reciprocate along the length direction of the transfer rail 110 to transport the parts to be assembled that are the first in the assembly order from the first loading station to the remaining loading stations in sequence.

[0056] In this embodiment, specifically Figure 4 As shown, the feeding track 105 of the first feeding assembly 108 is flush with the transfer track 110, so that the screws can be sequentially translated to the transfer track 110, so that the shifting device can sequentially deliver the screws to the second feeding station and the third feeding station. At the second feeding station and the third feeding station, the feeding track 105 of the second feeding assembly 109 is tilted, and the lower end of the feeding track 105 of the second feeding assembly 109 is suspended above the transfer track 110, so that the spring washer and the flat washer can fall and be set on the screws on the feeding track 105, thereby completing a combination of an assembled product.

[0057] In the optional solution of this embodiment, specifically, the shifting device includes a shifting assembly, and the shifting assembly includes a first driving device 112, a mounting platform 113 and a clamp. The clamp is used to clamp the screw, and the clamp is installed on the mounting platform 113. The first driving device 112 is specifically a long-stroke cylinder, and the first driving device 112 is connected to the mounting platform 113 to drive the mounting platform 113 to reciprocate along the length direction of the transfer track 110, so as to deliver the screws to the second loading station and the third loading station in turn. Preferably, the shifting assembly includes a slide rail assembly, the guide direction of the slide rail assembly is the length direction of the transfer track 110, and the slide rail assembly is used to guide the movement of the mounting platform 113.

[0058] More specifically, the clamp includes at least one pneumatic finger 114, and the number of pneumatic fingers 114 is one less than the number of loading stations; when the number of loading stations is greater than two, multiple loading stations are equidistantly arranged, and multiple pneumatic fingers 114 are equidistantly arranged along the length direction of the transfer track 110, and the spacing between the pneumatic fingers 114 is equal to the spacing between the loading stations.

[0059] In this embodiment, Figure 4 The operation logic of the transfer mechanism 101 is described by taking the structure shown in FIG. Figure 4 As shown, the figure shows three loading stations and two pneumatic fingers 114. The pneumatic finger 114 near the head end of the transfer track 110 is the first pneumatic finger, and the other pneumatic finger 114 is the second pneumatic finger. When the first driving device 112 drives the mounting platform 113 to reciprocate, the first pneumatic finger reciprocates between the first loading station and the second loading station, and the second pneumatic finger reciprocates between the second loading station and the third loading station.

[0060] In specific operation, the first pneumatic finger first moves a screw from the first loading station to the second loading station, and at the same time, the second pneumatic finger moves from the second loading station to the third loading station; after the screw clamped by the first pneumatic finger is provided with a spring washer, the first pneumatic finger releases the screw and moves from the second loading station back to the first loading station, and at the same time, the second pneumatic finger moves from the third loading station to the second loading station, and then the second pneumatic finger clamps the screw provided with the spring washer. When the first pneumatic finger moves the next screw from the first loading station to the second loading station, the second pneumatic finger can move the screw provided with the spring washer from the second loading station to the third loading station, so that the flat washer is provided on the screw, thereby forming an assembled finished product. With such a configuration, the moving range of the mounting table 113 can be relatively smaller, the space occupied by the device can be reduced, and the assembly efficiency of the parts can be improved.

[0061] In an optional solution of this embodiment, the shifting device also includes a slide 111; the slide 111 is installed on the side of the transfer track 110, and the mounting platform 113 is installed on the slide 111, and the slide 111 is used to drive the mounting platform 113 to approach or move away from the transfer track 110.

[0062] In this embodiment, based on the above description of the operating logic of the transfer mechanism 101, it can be known that the second loading station and the third loading station are both transfer points. At the second loading station, the screw is transferred from the first pneumatic finger to the second pneumatic finger. Before the first pneumatic finger returns to the head end of the transfer track 110 and the second pneumatic finger returns from the third loading station to the second loading station, the slide 111 needs to drive the mounting table 113 away from the transfer track 110 so that the return movement of the first pneumatic finger and the second pneumatic finger will not interfere with the parts placed on the transfer track 110. When the shifting assembly drives the workpiece to move to the subsequent loading station, the slide 111 needs to drive the mounting table 113 close to the transfer track 110 so that the pneumatic clamp can clamp the parts on the transfer track 110.

[0063] In an optional solution of this embodiment, the shifting assembly further includes a material shifting device 115; the material shifting device 115 is mounted on the mounting platform 113, and the material shifting device 115 is located on the side of the clamping jaw close to the unloading mechanism 102, so as to shift the assembled finished product to the unloading station. The distance between the material shifting portion of the material shifting device 115 and the adjacent pneumatic fingers 114 is less than the spacing between the pneumatic fingers 114.

[0064] In this embodiment, the operating principle of the material-dispensing device 115 is the same as that of the pneumatic finger 114, that is, when the first driving device 112 drives the mounting table 113 to reciprocate, the material-dispensing device 115 reciprocates between the third loading station and the unloading station. When the pneumatic finger 114 returns to the preceding loading station, the material-dispensing device 115 can return to the third loading station. Since the distance between the material-dispensing part of the material-dispensing device 115 and the adjacent pneumatic finger 114 is smaller than the spacing between the pneumatic fingers 114, the material-dispensing part of the material-dispensing device 115 is located at the retreat side of the assembled finished product (the direction of the unloading station is the forward side, and the reverse direction is the retreat side). When the pneumatic finger 114 transports the parts to the subsequent loading station, the material-dispensing part can push the assembled finished product forward from the retreat side and finally move to the unloading station. That is to say, while the pneumatic fingers 114 are loading the parts, the material shifting device 115 can shift the assembled finished products at the third loading station to the unloading station, thereby improving production efficiency.

[0065] In an optional solution of this embodiment, the transfer mechanism 101 further includes an in-position sensor 116, which is installed at the head end of the transfer track 110 to detect whether the parts to be assembled at the first loading station have moved to the position. The in-position sensor 116 is specifically a photoelectric sensor. When the screw is loaded in place, the photoelectric sensor senses that the part is in place, and the slide 111 can push the mounting table 113 to move in the direction close to the transfer track 110, so that the pneumatic clamp on the mounting table 113 clamps the screw and transports it to the subsequent loading station.

[0066] Embodiment 3

[0067] The fastener assembly device in the third embodiment is an improvement on any of the above embodiments. The technical contents disclosed in the above embodiments are not described repeatedly, and the contents disclosed in the above embodiments also belong to the contents disclosed in the third embodiment.

[0068] In an optional scheme of this embodiment, the unloading mechanism 102 includes a unloading screening device and a defective product unloading track 117; the unloading screening device includes a docking track 118, a second driving device 119 and a finished product inspection camera; the docking track 118 is located between the transfer mechanism 101 and the defective product unloading track 117, and the feed port of the docking track 118 can be docked with the transfer mechanism 101; the finished product inspection camera is installed on the docking track 118 to detect whether the assembled finished product is qualified; the second driving device 119 is specifically a pushing cylinder, which is used to drive the docking track 118 to move so that the discharge port of the docking track 118 is opposite to the defective product unloading track 117 or the collection bin 120.

[0069] In this embodiment, when the sensor detects that the assembled product is moved to the unloading station, the lifting cylinder can drive the docking track 118 to move upward so that the docking track 118 can dock with the transfer track 110 of the transfer mechanism 101, and a detection box is provided on the docking track 118, and the assembled product entering the docking track 118 can enter the detection box. The finished product inspection camera is lifted by the cylinder to inspect the assembled product in the detection box, so as to determine whether the assembled product is complete. When the assembled product is qualified, the discharge port of the docking track 118 is opposite to the collection bin 120, so that the assembled product is transported to the collection bin 120. When the assembled product is unqualified, the discharge port of the docking track 118 is opposite to the defective product unloading track 117, so that the assembled product is transported to the defective product unloading track 117, and finally transported to the defective product recovery bin.
