[0051] Fastener assembly is one of the important links in the product production process. The automated assembly of fasteners can improve the assembly efficiency of fasteners. In the automated assembly process of fasteners, the fasteners need to be transported to the power tool in an orderly manner so that the fasteners can be connected to the power tool, and then the power tool assembles the fasteners to the product. For larger fasteners, such as those with longer lengths or larger heads, they are easy to get stuck in the limited conveying space, making it difficult to convey the fasteners to the power tool, thereby affecting the assembly efficiency of the fasteners.

[0052] Based on the above considerations, the present application provides a fastener assembly device, equipment and system, wherein the fastener assembly device comprises: a feeding component, a fastening component, a feeding component and a switching component. The feeding component comprises a first channel for conveying fasteners, the fastening component comprises a sleeve and a second channel, one end of the sleeve is used to adsorb the fasteners, and the sleeve is configured to be able to reciprocate along the extension direction of the second channel. The feeding component comprises a feed port, a discharge port and a feeding channel connecting the feed port and the discharge port. The switching component is used to drive the feeding component to move between a first position and a second position, and when the feeding component is in the first position, the feed port is docked with the first channel to allow the fasteners to enter the feeding channel from the first channel via the feed port. When the feeding component is in the second position, the feed port is docked with the second channel to allow the sleeve to enter the feeding channel via the feed port to adsorb the fasteners and send the fasteners out of the discharge port.

[0053] By switching the position of the feeding assembly, the feeding channel is connected to the first channel or to the second channel. When the feeding channel is connected to the first channel, the feeding channel and the first channel together form a channel for fastener delivery, so that the fastener can smoothly move from the first channel to the feeding channel, reducing the phenomenon of fasteners getting stuck during delivery, and meeting the delivery needs of fasteners with longer lengths or larger heads. When the feeding channel is connected to the second channel, the feeding channel and the second channel together form a channel for the sleeve to move, so that the sleeve can smoothly move from the second channel to the feeding channel and absorb the fastener, and then the sleeve carries the fastener out of the feeding channel from the outlet for assembly. Among them, the first channel and the second channel are independent of each other, and the transportation of fasteners in the first channel and the movement of the sleeve in the second channel do not interfere with each other. By switching the position of the feeding channel, it is possible to smoothly transport the fasteners to the feeding channel and to move the sleeve to the feeding channel to adsorb the fasteners, thereby realizing a quick connection between the fasteners and the sleeve, and then facilitating the sleeve to carry the fasteners to a predetermined position for assembly, reducing the phenomenon of fasteners getting stuck during transportation and sleeves getting stuck during movement, improving the efficiency of fastener transportation, sleeve movement, and connection between fasteners and sleeves, and thus improving the efficiency of fastener assembly.

[0054] The fastener assembly device disclosed in the embodiment of the present application can be used for, but not limited to, the assembly of bolts or screws. A fastener assembly system can be formed using the fastener assembly device, fastener assembly equipment, etc. disclosed in the present application, which is conducive to reliable delivery of fasteners to improve the assembly efficiency of fasteners.

[0055] Combination Figure 1 and Figure 2 As shown, Figure 1 This is one of the structural schematic diagrams of the fastener assembly device in some embodiments of the present application. Figure 2 This is the second structural schematic diagram of the fastener assembly device of some embodiments of the present application.

[0056] The embodiment of the present application provides a fastener assembly device 10 , including: a feeding component 11 , a fastening component 12 , a feeding component 13 and a switching component 14 .

[0057] The feeding assembly 11 includes a first channel 111 for conveying fasteners, and the fastening assembly 12 includes a sleeve 121 and a second channel 122. One end of the sleeve 121 is used to absorb the fasteners, and the sleeve 121 is configured to be able to reciprocate along the extension direction of the second channel 122. The feeding assembly 13 includes a feed port, a discharge port, and a feeding channel 131 connecting the feed port and the discharge port. The switching assembly 14 is used to drive the feeding assembly 13 to move between a first position and a second position. When the feeding assembly 13 is in the first position, the feed port is docked with the first channel 111 to allow the fasteners to enter the feeding channel 131 from the first channel 111 through the feed port. When the feeding assembly 13 is in the second position, the feed port is docked with the second channel 122 to allow the sleeve 121 to enter the feeding channel 131 through the feed port to absorb the fasteners and send the fasteners out of the discharge port.

[0058] The feeding assembly 11 is a component for conveying fasteners, and compressed air may be used as a power for conveying the fasteners along the first channel 111 .

[0059] The fastening assembly 12 is a component used to connect with the fastener and provide a tightening torque for the fastener, wherein the second channel 122 is used to guide the sleeve 121 to move along its axial direction, so that the sleeve 121 can move to a specified position and adsorb the fastener, thereby achieving the connection between the sleeve 121 and the fastener, so that the sleeve 121 can carry the fastener to move and transmit the torque to the fastener. The way in which one end of the sleeve 121 adsorbs the fastener can be negative pressure adsorption.

[0060] The first channel 111 of the feeding assembly 11 and the second channel 122 of the fastening assembly 12 are independent of each other, that is, the conveying of the fastener in the first channel 111 and the movement of the sleeve 121 in the second channel 122 do not interfere with each other.

[0061] The feeding assembly 13 is a component for receiving the fasteners conveyed by the first channel 111 and enabling the sleeve 121 to move into the feeding assembly 13 to adsorb the fasteners. The feeding channel 131 of the feeding assembly 13 is independent of the first channel 111 and the second channel 122. Under the drive of the switching assembly 14, the feeding channel 131 can be connected to and communicated with the first channel 111 or with the second channel 122.

[0062] like Figure 1 As shown, when the feeding channel 131 is connected to the first channel 111, the fasteners conveyed by the first channel 111 enter the feeding channel 131 through the feeding port. Figure 2 As shown, when the feeding channel 131 is docked with the second channel 122, the sleeve 121 in the second channel 122 can be extended from the feed port, and the fasteners in the feeding channel 131 are adsorbed by one end of the sleeve 121, and the fasteners are carried out from the discharge port to the outside of the feeding channel 131 under the movement of the sleeve 121, so that the fasteners can fully contact with the workpiece to be assembled, and sufficient assembly space is provided for the assembly of the fasteners, which can meet the assembly requirements of some fasteners such as countersunk screws.

[0063] In some embodiments, the switching assembly 14 can be configured as a cylinder assembly. The axis of the first channel 111 can be arranged parallel to the axis of the second channel 122, and the cylinder assembly drives the feeding assembly 13 to switch between the first position and the second position in a direction perpendicular to the axis of the first channel 111. Alternatively, the axis of the first channel 111 can be arranged at an angle to the axis of the second channel 122, and the cylinder assembly drives the feeding assembly 13 to rotate to switch between the first position and the second position.

[0064] By switching the position of the feeding assembly 13, the feeding channel 131 is connected to the first channel 111 or to the second channel 122. When the feeding channel 131 is connected to the first channel 111, the feeding channel 131 and the first channel 111 jointly form a channel for fastener delivery, so that the fastener can smoothly move from the first channel 111 to the feeding channel 131, reducing the phenomenon of fasteners getting stuck during the delivery process, and meeting the delivery requirements of fasteners with longer lengths or larger heads. When the feeding channel 131 is connected to the second channel 122, the feeding channel 131 and the second channel 122 jointly form a channel for the sleeve to move, so that the sleeve 121 can smoothly move from the second channel 122 to the feeding channel 131 and absorb the fastener, and then the sleeve 121 carries the fastener and moves out of the feeding channel 131 from the discharge port for assembly. Among them, the first channel 111 and the second channel 122 are independent of each other, and the transportation of fasteners in the first channel 111 and the movement of the sleeve 121 in the second channel 122 do not interfere with each other. By switching the position of the feeding channel 131, it is convenient to smoothly transport the fasteners to the feeding channel 131, and it is also convenient for the sleeve 121 to move into the feeding channel 131 to adsorb the fasteners, thereby realizing a quick connection between the fasteners and the sleeve 121, and then facilitating the sleeve 121 to carry the fasteners to a predetermined position for assembly, reducing the phenomenon of fasteners getting stuck during transportation and the sleeve 121 getting stuck during movement, improving the efficiency of fastener transportation, sleeve 121 movement, and fastener and sleeve 121 connection, thereby improving the efficiency of fastener assembly.

[0065] Combination Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the switching assembly 14 includes a pivot 141 and a first driving member 142. The feeding assembly 13 is movably connected to the pivot 141, and the first driving member 142 is used to drive the feeding assembly 13 to rotate around the pivot 141, so that when the feeding assembly 13 is in the first position, the feeding channel 131 is connected to the first channel 111 in a center-aligned manner, and when the feeding assembly 13 is in the second position, the feeding channel 131 is connected to the second channel 122 in a center-aligned manner.

[0066] The pivot 141 is a component around which the feeding assembly 13 rotates. In some embodiments, a through hole is provided on the feeding assembly 13, and the pivot 141 is inserted into the through hole. During the rotation of the feeding assembly 13 around the pivot 141, the feeding channel 131 can also rotate around the pivot 141, that is, the feeding assembly 13 switches its position by rotating. Accordingly, the axis of the first channel 111 and the axis of the second channel 122 are arranged at an angle, so that the first channel 111 or the second channel 122 can dock with the feeding channel 131.

[0067] Center alignment means that the axes of the two adjacent channels coincide with each other. When the axes of the first channel 111 and the feeding channel 131 coincide with each other, the first channel 111 and the feeding channel 131 can jointly form a continuous channel for fastener delivery, so that the fasteners can enter the feeding channel 131 more smoothly when being delivered along the axis of the first channel 111, thereby reducing the phenomenon of fasteners getting stuck at the joint between the first channel 111 and the feeding channel 131, and improving the efficiency of fastener delivery. Similarly, when the axes of the second channel 122 and the feeding channel 131 coincide with each other, the second channel 122 and the feeding channel 131 can jointly form a continuous channel for the sleeve 121 to move, so that the sleeve 121 can enter the feeding channel 131 more smoothly when being delivered along the axis of the second channel 122, thereby reducing the phenomenon of sleeve 121 getting stuck at the joint between the second channel 122 and the feeding channel 131, and reducing the wear of the sleeve 121.

[0068] In some embodiments, the first driving member 142 may be configured as a cylinder.

[0069] The position of the feeding assembly 13 is switched by rotation, thereby achieving communication between the feeding channel 131 and the first channel 111 or the second channel 122, which can reduce the phenomenon of fasteners getting stuck during transportation and the sleeve 121 getting stuck during movement.

[0070] Combination Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the switching assembly 14 further includes a stopper 143 and a second driving member 144. The second driving member 144 is used to drive the stopper 143 to move to block or open the discharge port.

[0071] When the feeding channel 131 is connected with the first channel 111, the discharging port is blocked by the stopper 143, and the fasteners input through the first channel 111 can be stopped at the discharging port by the stopper 143, so as to be temporarily stored in the feeding channel 131. When the feeding channel 131 is connected with the second channel 122, after the sleeve 121 absorbs the fasteners in the feeding channel 131, the stopper 143 opens the discharging port, so that one end of the sleeve 121 can carry the fasteners and extend out of the discharging port. Compared with the method of setting an elastic block at the discharging port and squeezing the elastic block open by one end of the sleeve 121 to deliver the fasteners out of the discharging port, the active movement of the stopper 143 can fully open the discharging port, which can meet the needs of fasteners with larger heads such as countersunk screws to extend out of the discharging port, and reduce the wear of the sleeve 121 due to extrusion and the phenomenon of fasteners falling off.

[0072] In some embodiments, the second driving member 144 may be configured as a cylinder.

[0073] The second driving member 144 drives the stopper 143 to move so that the stopper 143 actively blocks or opens the discharge port, which can stop the fastener at the discharge port and facilitate the fastener and one end of the sleeve 121 to extend from the discharge port, thereby meeting the needs of fasteners with larger heads such as countersunk screws to extend from the discharge port.

[0074] Combination Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the switching assembly 14 further includes a clamping member 145 and a third driving member 146. The third driving member 146 is used to drive the clamping member 145 to clamp the fastener located in the feeding channel 131.

[0075] After the fasteners in the first channel 111 are transported to the feeding channel 131, the fasteners are clamped in the feeding channel 131 by the clamping member 145, thereby fixing the fasteners to reduce the shaking of the fasteners when the feeding assembly 13 rotates to the second position, thereby facilitating one end of the sleeve 121 to accurately absorb the fasteners in the feeding channel 131.

[0076] In some embodiments, the clamping member 145 can be configured as a pin, and the third driving member 146 can be configured as a cylinder. The axis of the pin is perpendicular to the axis of the feeding channel 131, and the cylinder drives the pin to move in the direction of its axis so that the end of the pin can abut against the side of the fastener.

[0077] The fastener is stably clamped in the feeding channel 131 by the clamping member 145 to reduce the shaking of the fastener during the rotation of the feeding assembly 13 , thereby facilitating one end of the sleeve 121 to accurately absorb the fastener in the feeding channel 131 .

[0078] Combination Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the fastening assembly 12 further includes a fourth driving member 123 and a fifth driving member 124. The fourth driving member 123 is used to drive the sleeve 121 to reciprocate along the central axis direction of the second channel 122 when the feeding assembly 13 is in the second position. The fifth driving member 124 is used to drive the sleeve 121 to rotate so as to assemble the fastener to the target mounting hole.

[0079] In some embodiments, the fourth driving member 123 may include a first cylinder 1231 and a second cylinder 1232. The fourth driving member 123 may send the fastener adsorbed by one end of the sleeve 121 out of the discharge port through a two-stage drive. In the first stage of driving, the first cylinder 1231 drives one end of the sleeve 121 to extend into the feeding channel 131 and adsorb the fastener in the feeding channel. After confirming that the fastener is adsorbed well, the second stage of driving is performed, that is, the first stage of driving plays the role of the sleeve 121 adsorbing and the fastener recognizing the cap. In the second stage of driving, the second cylinder 1232 continues to drive one end of the sleeve 121 to carry the fastener out of the discharge port. After the fastener is assembled, the first cylinder 1231 and the second cylinder 1232 drive the sleeve 121 back into the second channel 122, so that the feeding assembly 13 can rotate to the first position to receive the next fastener.

[0080] In some embodiments, the fifth driving member 124 may be a motor, which drives the sleeve 121 to rotate, thereby driving the fastener to rotate, that is, transmitting the torque to the fastener through the sleeve 121, so that the fastener can be assembled into the target mounting hole. Among them, one end of the sleeve 121 is adapted to the head of the fastener, for example, the fastener is a hexagonal head bolt, and one end of the sleeve is provided with a hexagonal groove.

[0081] In some embodiments, Figure 1 and Figure 2 As shown, an air slip ring is sleeved on the sleeve 121 to reduce the friction force during the rotation and movement of the sleeve 121.

[0082] The fourth driving member 123 drives the sleeve 121 to move, so as to achieve the connection between the sleeve 121 and the fastener and to send the fastener out of the material outlet. The fifth driving member 124 drives the sleeve 121 and the fastener to rotate, so as to apply a tightening torque to the fastener to complete the assembly of the fastener.

[0083] According to some embodiments of the present application, the fastening assembly 12 further includes a vacuum generator, which is connected to a cavity at one end of the sleeve 121 so that the one end of the sleeve 121 can absorb the fastener.

[0084] The vacuum generator is a component used to generate negative pressure. Under the action of the vacuum generator, the pressure in the cavity is reduced so that one end of the sleeve connected to the cavity can absorb the fastener. After the fastener is assembled, the vacuum generator is turned off, and one end of the sleeve 121 returns to normal pressure, thereby separating from the fastener.

[0085] The connection between the sleeve 121 and the fastener is achieved through negative pressure, which improves the convenience of connecting or separating the sleeve 121 and the fastener.

[0086] According to some embodiments of the present application, the fastening assembly 12 further includes a pressure sensor, and the pressure sensor is used to detect the pressure value of the cavity at one end of the sleeve 121 used to adsorb the fastener.

[0087] When one end of the sleeve 121 adsorbs the fastener, the pressure sensor detects the pressure value in the cavity. If the pressure value in the cavity can be maintained within a stable preset range, it indicates that one end of the sleeve 121 can provide sufficient suction to adsorb the fastener. At this time, the sleeve 121 is well connected to the fastener, thereby completing the fastener recognition. If the pressure value in the cavity cannot be maintained within a stable preset range, it indicates that the connection between the sleeve 121 and the fastener is unreliable, and the subsequent assembly has problems such as the torque cannot be effectively transmitted to the fastener and the fastener is easy to fall off. Among them, the situation of unreliable connection can include that the fastener is tilted, and one end of the sleeve 121 is difficult to fully contact with the fastener; or the size of the fastener head does not match the size of one end of the sleeve. The size mismatch includes that the size of the fastener head is large, which makes it difficult for the fastener head to extend into the sleeve 121, or the size of the fastener head is small, and there is a large gap between the fastener head and the sleeve 121 after the fastener head extends into the sleeve 121.

[0088] By setting a pressure sensor to detect the pressure value, the reliability of the connection between one end of the sleeve 121 and the fastener can be judged by the pressure value.

[0089] Combination Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the fastener assembly device 10 also includes an adjustment component 16, which is used to adjust the alignment of the center axis of the feeding channel 131 with the center axis of the first channel 111 when the feeding component 13 is in the first position, or to adjust the alignment of the center axis of the feeding channel 131 with the center axis of the second channel 122 when the feeding component 13 is in the second position.

[0090] During the movement of the feeding assembly 13, the first position and the second position are equivalent to the two extreme positions of the feeding assembly 13, and the adjustment assembly 16 is a component for adjusting the extreme positions of the feeding assembly. When the alignment degree of the central axis of the feeding channel 131 and the central axis of the first channel 111 is good, the problem of the fastener being stuck in the connection part between the feeding channel 131 and the first channel 111 can be reduced. When the alignment degree of the central axis of the feeding channel 131 and the central axis of the second channel 122 is good, the problem of the sleeve 121 being stuck in the connection part between the feeding channel 131 and the first channel 111 can be reduced.

[0091] In some embodiments, the adjustment component 16 can be configured as an adjustment screw, which can limit the feeding component 13 by adjusting the depth of the screw, thereby adjusting the extreme position of the feeding component 13 during the rotation process.

[0092] By setting the adjustment component 16 to adjust the extreme position of the feeding component, the accuracy of the feeding component 13 in the first position and the second position is improved, and the alignment of the feeding channel 131 with the first channel 111 and the alignment of the feeding channel 131 with the second channel 122 are further improved, thereby improving the comfort of fastener delivery and the smoothness of the movement of the sleeve 121.

[0093] like Figure 3 As shown, Figure 3 This is one of the structural schematic diagrams of the fastener assembly equipment of some embodiments of the present application. The embodiment of the second aspect of the present application provides a fastener assembly equipment 100, including at least one fastener assembly device 10 and a conveying device 20 as in the above embodiment, the conveying device 20 includes a silo 21 and a conveying line 22, the silo 21 is used to accommodate fasteners, and the conveying line 22 connects the silo 21 and the first channel 111 of the feeding component 11 of the fastener assembly device 10 respectively.

[0094] In some embodiments, the fastener assembly equipment 100 may also include a barcode scanner, which is used to identify the barcode on the outer packaging of the material, thereby determining that the material in the package is the fastener required for this assembly, and can identify the model of the fastener, and pour the fasteners identified by the scan into the silo 21, and the fasteners are arranged in order by the conveyor line 22 and conveyed to the first channel 111.

[0095] In some embodiments, the conveying device 20 can be configured as a stepped automatic nail feeder to achieve functions such as orderly arrangement of fasteners and automatic loading.

[0096] The fastener assembly device 100 in this embodiment can have all the beneficial effects of the above-mentioned fastener assembly device 10 , which will not be described in detail here. At the same time, with the cooperation of the conveying device 20 , the fasteners can be conveyed to the first channel 111 in an orderly manner.

[0097] like Figure 3 As shown, according to some embodiments of the present application, the fastener assembly equipment 100 also includes a sorting device 30, which is arranged on the conveyor line 22, and the sorting device 30 is used to sort the fasteners in the conveyor line and provide fasteners of a size matching the fastener assembly device 10 to the first channel 111.

[0098] In some embodiments, the sorting device may include a fastener length detection component and a rejection component. The fastener length detection component detects the length dimensions of the fasteners arranged on the conveyor line in sequence, and the rejection component rejects the fasteners with unqualified length dimensions from the conveyor line 22, thereby conveying the fasteners with qualified length dimensions to the fastener assembly device 10.

[0099] By providing the sorting device 30, the pass rate of the fasteners used in the assembly is improved, and the quality of the assembly is further improved.

[0100] like Figure 3 As shown, according to some embodiments of the present application, the fastener assembly equipment 100 further includes a cleaning device 40 , which is disposed on the conveyor line 22 , and is used to clean the fasteners conveyed in the conveyor line 22 .

[0101] The friction between the fasteners will generate certain debris, which will adhere to the surface of the fasteners. Before the fasteners enter the first channel 111, the debris on the surface of the fasteners can be cleaned by the cleaning device 40, which can reduce the problem of debris entering the first channel 111. The cleaning method of the cleaning device 40 can be to blow away the debris on the surface of the fasteners by blowing air, or to absorb the debris on the surface of the fasteners by negative pressure adsorption.

[0102] The fasteners entering the first channel 111 are cleaned by the cleaning device 40 to reduce the debris on the fasteners from entering the first channel, thereby alleviating the influence of the debris on the adsorption effect of the sleeve on the fasteners and improving the service life of the fastener assembly device 10.

[0103] like Figure 3 As shown, according to some embodiments of the present application, the cleaning device 40 includes a positive pressure cleaning component 41 and / or a negative pressure cleaning component 42. The positive pressure cleaning component 41 is used to output gas toward the conveying line 22. The negative pressure cleaning component 42 includes a stopper 421 and a negative pressure component 422, the stopper 421 is used to stop the fastener at the cleaning position on the conveying line 22, and the negative pressure component 422 is used to form negative pressure at the cleaning position.

[0104] The positive pressure cleaning assembly 41 can output compressed air toward the conveying line 22, thereby cleaning the debris on the surface of the fastener in a blowing manner. At the same time, the positive pressure cleaning assembly 41 can also blow away the fasteners that are offset on the conveying line 22 to play a role in removing them.

[0105] The negative pressure cleaning assembly 42 stops the fastener through the stopper 421, so that the fastener can temporarily stay in the cleaning position. At this time, the negative pressure member 422 is opened, thereby forming a negative pressure in the cleaning position to absorb the debris on the surface of the fastener. After cleaning, the stopper 421 is removed, and the fastener continues to be transported by the conveyor line 22. Among them, the negative pressure member 422 can be configured as a suction fan.

[0106] By providing the positive pressure cleaning component 41 to clean the fasteners by blowing air, and the negative pressure cleaning component 42 to clean the fasteners by suction, sufficient cleaning of the fasteners can be achieved.

[0107] like Figure 4 As shown, Figure 4 This is the second structural schematic diagram of the fastener assembly device of some embodiments of the present application. According to some embodiments of the present application, the fastener assembly device 100 also includes a visual recognition device and a robotic arm 50. The visual recognition device is used to obtain the position information of the target mounting hole on the workpiece to be assembled, and the robotic arm 50 is used to drive the fastener assembly device 10 to move according to the position information.

[0108] In some embodiments, the visual recognition device can be configured as a camera, which captures an image of the workpiece to be assembled and identifies the target installation hole on the image, thereby determining the position information of the target installation hole. The robotic arm 50 moves the fastener assembly device 10 to the target installation hole according to the position information, so that the discharge port of the fastener assembly device 10 is aligned with the target installation hole, and the sleeve 121 carrying the fastener can just enter the target installation hole after extending out of the discharge port.

[0109] By cooperating with the visual recognition device and the robot arm 50, the fastener assembly device 10 can be accurately moved to the target installation hole, thereby improving the efficiency and quality of fastener assembly.

[0110] like Figure 5 and Figure 6 As shown, Figure 5 This is one of the structural schematic diagrams of the fastener assembly system in some embodiments of the present application. Figure 6 This is the second structural schematic diagram of the fastener assembly system of some embodiments of the present application.

[0111] An embodiment of the third aspect of the present application provides a fastener assembly system 1000, which includes a fastener assembly device 100 as in the above embodiment, wherein the fastener assembly device 100 is provided with multiple, a part of the multiple fastener assembly devices 100 is located on one side of the travel direction F of the workpiece to be assembled, and the rest of the multiple fastener assembly devices 100 is located on the other side of the travel direction F of the workpiece to be assembled.

[0112] In some embodiments, the fastener assembly system 1000 may include two fastener assembly devices 100, each of which includes two fastener assembly devices 10. One of the fastener assembly devices 100 is located on one side of the travel direction F of the workpiece to be assembled, and the other fastener assembly device 100 is located on the other side of the travel direction F of the workpiece to be assembled, so that fasteners can be assembled synchronously on the target mounting holes located on both sides of the workpiece to be assembled.

[0113] On the basis that the fastener assembly device 100 improves the efficiency of fastener conveying, sleeve 121 movement, and connection between the fastener and the sleeve 121 , by arranging a plurality of fastener assembly devices 100 in the fastener assembly system 1000 , the efficiency of fastener assembly is further improved.

[0114] Combine the following Figures 1 to 7 The embodiments of the present application are described in further detail. Figure 7 This is a schematic diagram of the fastener assembly process according to some embodiments of the present application.

[0115] The fastener assembly device 10 includes: a feeding component 11, a fastening component 12, a feeding component 13, a switching component 14, an air slip ring 15 and an adjusting component 16.

An air slip ring is sleeved on the sleeve 121. The axis of the first channel 111 and the axis of the second channel 122 are set at an angle.

[0118] The feeding assembly 13 includes a feeding port, a discharging port, and a feeding channel 131 connecting the feeding port and the discharging port.

[0119] The switching assembly 14 is used to drive the feeding assembly 13 to move between the first position and the second position. When the feeding assembly 13 is in the first position, the feeding port is docked with the first channel 111 to allow the fastener to enter the feeding channel 131 from the first channel 111 through the feeding port. When the feeding assembly 13 is in the second position, the feeding port is docked with the second channel 122 to allow the sleeve 121 to enter the feeding channel 131 through the feeding port to absorb the fastener and send the fastener out of the outlet.

[0120] The switching assembly 14 includes a pivot 141, a first driving member 142, a stopper 143, a second driving member 144, a clamping member 145 and a third driving member 146. The feeding assembly 13 is rotatably arranged on the pivot 141, and the first driving member 142 configured as a cylinder is used to drive the feeding assembly 13 to rotate to achieve position switching. The second driving member 144 configured as a cylinder is used to drive the stopper 143 to move to block or open the discharge port. The third driving member 146 configured as a cylinder is used to drive the clamping member 145 configured as a ejector to move to clamp or release the fastener in the feeding channel 131.

[0121] The fastening assembly 12 also includes a fourth driving member 123, a fifth driving member 124, a vacuum generator and a pressure sensor. The fourth driving member 123 includes a first cylinder 1231 and a second cylinder 1232. The first cylinder 1231 is used to drive the sleeve 121 to extend into the feeding channel 131 to contact the fastener, and to use negative pressure to adsorb the fastener under the action of the vacuum generator. The pressure value detected by the pressure sensor is used to determine that the fastener adsorption effect is good, thereby completing the fastener cap recognition. The fifth driving member 124 is used to output torque to the sleeve 121.

[0122] The adjusting component 16 is configured as an adjusting screw, and the adjusting screw is used to adjust the extreme position of the feeding component 13 during rotation, that is, to adjust the accuracy of the feeding component 13 in the first position and the second position.

[0123] The assembly process of fasteners is explained using the assembly of screws as an example.

[0124] The screws are poured into the silo 21 of the fastener assembly equipment 100, and the feeding assembly 13 of the fastener assembly device 10 is switched to the first position, thereby preparing for the input of the screws. The conveying of the screws on the conveyor line 22 and the shooting of the camera are carried out synchronously, and the mechanical arm 50 drives the fastener assembly device 10 to move to align with the target mounting hole according to the position of the target mounting hole identified by the camera. The screws are transported on the conveyor line 22. The length detection and cleaning are completed, and the screws are blown into the first channel 111 by compressed air, and then enter the feeding channel 131, and are stopped at the discharge port by the action of the stopper 143, and the screws are clamped by the ejector. The feeding assembly 13 is switched to the second position, and the first cylinder 1231 is driven to drive the sleeve 121 to contact the screw, the vacuum generator opens the negative pressure and the pressure value is detected by the pressure sensor. If the pressure value does not meet the requirements, it means that the connection between the sleeve 121 and the screw is unreliable, and an alarm is issued and it is handled manually. When the pressure value meets the requirement, the connection between the sleeve 121 and the screw is reliable, and the cap recognition is completed, the block 143 opens the discharge port, and the second cylinder 1232 drives the sleeve 121 to carry the screw out of the discharge port, and the fifth driving member 124 drives the sleeve 121 and the screw to rotate, so as to assemble the screw in the target installation hole.
