Description

Technical Field

[0001] This application relates to the technical field of sorting equipment, and particularly to a fastener sorting equipment. Background Art

[0002] Fasteners, as mechanical parts for connection and fixation, are widely used in mechanical equipment, transportation vehicles, buildings, etc. During the process of conveying fasteners to the assembly position, there may be some fasteners with specification errors that do not meet the specification requirements among a large number of fasteners. Therefore, a device that can efficiently and accurately detect and divert fasteners is needed. Summary of the Utility Model

[0003] An embodiment of this application provides a fastener sorting equipment, which includes a conveying device, a detection device arranged on the conveying device, and a diversion device electrically connected to the detection device. The diversion device is communicated with one end of the conveying structure of the conveying device, and can realize efficient and accurate detection and diversion of fasteners.

[0004] Another embodiment of this application provides a fastener sorting equipment. The conveying structure is arranged on the conveying member and is set in a structural form including a conveying chute and a supporting surface. It can provide support for a part of the fastener through the supporting surface to facilitate the movement of the fastener along the conveying structure, and can also accommodate another part of the fastener through the conveying chute to limit the movement path and supporting position of the fastener on the conveying structure. Thus, at least a part of each fastener can be in a determined position relative to the conveying member, which is beneficial to improving the accuracy of detecting fasteners by the detection device.

[0005] Another embodiment of this application provides a fastener sorting equipment. Since the conveying and pushing structure cooperates with the conveying chute on the conveying member to form a semi-closed conveying channel, the fasteners can be completely in the conveying channel to shield the fasteners through the conveying channel, which is beneficial to reducing the influence of the external environment on the fasteners.

[0006] Another embodiment of this application provides a fastener sorting equipment. A force towards the feed port can be applied to the fasteners through the conveying and pushing structure, so that the fasteners can enter the feed port in sequence, and further, the fastener sorting equipment can continuously detect and convey the fasteners.

[0007] Another embodiment of the present application provides a fastener sorting device. Since the first detection member is arranged on the conveying device and the distance between the first detection member and the support surface is greater than the length of the part of the required fastener located in the conveying chute, when an over-length fastener passes through the first detection member, the first detection member can be triggered, so that the first detection member can generate a corresponding detection signal, and then the over-length fasteners that exceed the specified length requirements can be detected and identified.

[0008] Another embodiment of the present application provides a fastener sorting device. Since the second detection member and the third detection member are arranged on the conveying device, the second detection member can detect the part of the fastener supported on the support surface, and the third detection member has a first distance from the support surface. All the fasteners conveyed through the conveying channel can be detected by the second detection member, and the ultra-short fasteners with a length shorter than the length of the required fastener can be detected according to whether the third detection member is triggered, so that the application scenarios of the fastener sorting device can be increased.

[0009] Another embodiment of the present application provides a fastener sorting device. Since the detection device includes a weighing scale, it can be determined whether the fastener is the required specification fastener according to the weight of the fastener detected by the weighing scale, which can be applicable to the situation where there are various fasteners that do not meet the specification length requirements, and is beneficial to improving the applicability of the fastener sorting device.

[0010] Another embodiment of the present application provides a fastener sorting device. Since a detection signal is associated with a fastener of a certain structural type, the detection and diversion of fasteners of different specifications can be realized.

[0011] Another embodiment of the present application provides a fastener sorting device. Since the diversion component is movably arranged on the diversion base body and a diversion channel is arranged on the diversion component, the diversion component can be driven by a driving member to move relative to the diversion base body, so that the diversion channel can be communicated with the feed inlet on the diversion base body. At this time, the fastener can enter the diversion channel through the feed inlet; the diversion channel can also be communicated with an outlet on the diversion base body. At this time, the fastener can be conveyed from the corresponding outlet to the corresponding position, so that the diversion of the fastener can be realized.

[0012] Another embodiment of the present application provides a fastener sorting device. Since a feeding member is arranged at the outlet, the feeding member can be extended to the material using position to facilitate the conveyance of the fasteners diverted from the outlet to the material using position; at the same time, a second blowing channel is arranged on the feeding member, and gas can be blown into the feeding member through the second blowing channel, so that the fasteners can be driven by the air flow to move quickly in the feeding member, which is beneficial to improving the conveyance efficiency of the fasteners.

[0013] To achieve one or more of the above objects, the fastener sorting device provided by the embodiments of the present application includes: a conveying device having a conveying structure matching the fasteners, and the conveying structure can provide support for a part of the fasteners; a detection device arranged at a position adjacent to the conveying structure on the conveying device for detecting the fasteners conveyed through the conveying structure; a shunting device having a feeding port and at least two discharging ports, the feeding port is communicated with one end of the conveying structure, and the shunting device is electrically connected to the detection device and can shunt the fasteners from the feeding port to one of the discharging ports according to the detection signal of the detection device.

[0014] In the technical solution of the embodiments of the present application, since a conveying structure is arranged on the conveying device, the fasteners can be supported by the conveying structure and conveyed to the shunting device. And a detection device is arranged at a position adjacent to the conveying structure. During the process of the fasteners being conveyed through the conveying structure, the fasteners can be detected, so as to determine whether the specifications of the fasteners meet the requirements. At the same time, the detection device is electrically connected to the shunting device, and the movement of the shunting device can be controlled according to the detection signal generated by the detection device, so that fasteners of different specifications can be shunted from the corresponding discharging ports to the corresponding positions. Therefore, the fastener sorting device provided by the embodiments of the present application can detect and shunt the fasteners efficiently and accurately. BRIEF DESCRIPTION OF THE DRAWINGS

It is necessary to sort the fasteners to remove the fasteners of wrong specifications. It is necessary to sort the fasteners to transport fasteners of different specifications to the correct assembly position, or to remove the fasteners of wrong specifications.

[0037] The present application embodiment provides a fastener sorting device, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 The schematic diagram of the structure of the fastener sorting device provided in the embodiment of the present application is shown. Figure 2 The structure diagram of the conveying device in the fastener sorting device provided in the embodiment of the present application is shown. Figure 3 The embodiment of the present application provides Figure 2 Schematic diagram of the cross-section in the AA direction, Figure 4 A cross-sectional schematic diagram of a flow diversion device in a fastener sorting device provided in an embodiment of the present application is shown.

[0038] The fastener sorting device provided by the embodiment of the present application includes: a conveying device 1, a detection device 2, and a diversion device 3. Among them, the conveying device 1 has a conveying structure 11 that matches the fastener 6, and the conveying structure 11 can provide support for a part of the fastener 6; the detection device 2 is arranged at a position adjacent to the conveying structure 11 on the conveying device 1 for detecting the fastener 6 conveyed through the conveying structure 11; the diversion device 3 has a feed inlet 311 and at least two discharge outlets 312, the feed inlet 311 is communicated with one end of the conveying structure 11, and the diversion device 3 is electrically connected to the detection device 2 and can divert the fastener 6 from the feed inlet 311 to one of the discharge outlets 312 according to the detection signal of the detection device 2.

[0039] In the embodiment of the present application, the fastener 6 can be a standard part or a non-standard part such as a screw, a bolt, a stud, a nut, etc. For the convenience of description and explanation, the following takes the fastener 6 as a bolt as an example for illustration. The bolt includes a head 61 and a shank 62, the diameter of the head 61 is larger than that of the shank 62. After passing the shank 62 through the hole in the mechanical part, the head 61 can abut against the edge of the hole in the mechanical part, and at least a part of the shank 62 has an external thread, and the shank 62 can be connected to the internal thread on the mechanical part or connected to a nut.

[0040] In the embodiment of the present application, as Figure 2 shown, the fastener 6 can be sequentially transferred in the fastener sorting device through the conveying device 1 to move the fastener 6 from the accommodating position to the diversion device 3.

[0041] Exemplarily, a conveying structure 11 can be arranged in the conveying device 1 to transfer the fastener 6 through the conveying structure 11. For example, according to the structural characteristics of the fastener 6, a conveying structure 11 that can provide support for at least a part of the fastener 6 can be set. In this way, by placing the fastener 6 in the conveying structure 11, the fastener 6 can move along the conveying structure 11.

[0042] In the embodiment of the present application, as Figure 3 shown, the detection device 2 can be arranged on the conveying device 1 or other parts of the fastener sorting device, and the detection device 2 is adjacent to the conveying structure 11. For example, the detection device 2 is fixed on the conveying device 1, and the trigger member in the detection device 2 extends into the conveying structure 11, or the probe in the detection device 2 is located at a position on the conveying device 1 close to the conveying structure 11, and the light beam, sound wave, etc. emitted by the probe can be transmitted into the conveying structure 11. In this way, during the process of the fastener 6 being conveyed through the conveying structure 11, the fastener 6 may trigger the detection device 2, so that the fastener 6 can be detected by the detection device 2.

[0043] In the embodiment of the present application, as Figure 1 and Figure 4As shown, a feed inlet 311 and a plurality of discharge outlets 312 can be provided on the shunt device 3. For example, by setting the feed inlet 311 at a position on the shunt device 3 corresponding to the conveying device 1, the fastener 6 can enter the feed inlet 311 through the conveying structure 11 and thus enter the shunt device 3. The number of discharge outlets 312 in the shunt device 3 can be set according to the application scenario of the fastener sorting device. For example, when it is necessary to sort fasteners 6 of two specifications, two discharge outlets 312 can be set; when it is necessary to sort fasteners 6 of three specifications, three discharge outlets 312 can be set. The embodiment of the present application does not limit the number of discharge outlets 312 in the shunt device 3.

[0044] Exemplarily, the shunt device 3 can be electrically connected to the detection device 2, such as by electrically connecting the shunt device 3 and the detection device 2 through a wire, or by wireless network, so that electrical signals can be transmitted between the shunt device 3 and the detection device 2. Then, after the fastener 6 triggers the detection device 2, the shunt device 3 can be controlled according to the detection signal generated by the detection device 2, and the shunt device 3 can thus move between at least two discharge outlets 312, so as to convey different fasteners 6 from different discharge outlets 312 to corresponding positions.

[0045] In the fastener sorting device provided by the embodiment of the present application, since the conveying structure 11 is provided on the conveying device 1, the fastener 6 can be supported by the conveying structure 11 and the fastener 6 can be conveyed to the shunt device 3. And a detection device 2 is provided at a position adjacent to the conveying structure 11. During the process of the fastener 6 being conveyed by the conveying structure 11, the fastener 6 can be detected, so as to determine whether the specification of the fastener 6 meets the requirements. At the same time, by electrically connecting the detection device 2 and the shunt device 3, the movement of the shunt device 3 can be controlled according to the detection signal generated by the detection device 2, so that different specifications of fasteners 6 can be shunted from the corresponding discharge outlets 312 to the corresponding positions, thereby improving the efficiency and accuracy of detecting and shunting the fasteners 6.

[0046] In some possible embodiments of the present application, the conveying device 1 includes a conveying member 12, the conveying structure 11 includes a conveying chute 111 provided on the conveying member 12, the conveying chute 111 penetrates the conveying member 12 along the length direction of the conveying member 12, the conveying structure 11 further includes a support surface 112 on the opening side of the conveying chute 111 on the conveying member 12, the support surface 112 can support a part of the fastener 6, and the conveying chute 111 can accommodate another part of the fastener 6.

[0047] In the embodiment of the present application, such as Figure 1 、 Figure 2 and Figure 3As shown, a conveying member 12 can be provided in the conveying device 1, and a conveying structure 11 can be provided on the conveying member 12.

[0048] Exemplarily, the conveying member 12 can be a long strip structure with an overall structure approximately rectangular parallelepiped-shaped. Then, grooves can be provided on the long strip-shaped rectangular parallelepiped, and the grooves can be used as the conveying chute 111. As Figure 3 shown, the conveying chute 111 penetrates through the conveying member 12 along the long strip-shaped conveying member 12. For example, the width of the conveying chute 111 is set to be greater than the diameter of the rod portion 62 of the fastener 6 and less than the diameter of the head portion 61 of the fastener 6. In this way, the rod portion 62 of the fastener 6 can be accommodated in the conveying chute 111. As Figure 2 and Figure 3 shown, the surface on the opening side of the conveying chute 111 on the conveying member 12 can also be used as a part of the conveying structure 11, that is, the surfaces on both sides of the opening side of the conveying chute 111 are used as the supporting surfaces 112. In this way, the surface of the head portion 61 of the fastener 6 connected to the rod portion 62 can be abutted and supported on the two supporting surfaces 112, so that the fastener 6 is in an approximately suspended posture in the conveying structure 11.

[0049] Alternatively, referring to Figure 5 , Figure 5 which shows the structural schematic of the conveying device in the fastener sorting equipment provided by the embodiment of the present application Figure 2 。It is also possible to set the conveying chute 111 on the conveying member 12 to match the head portion 61 of the fastener 6, and one surface on one side of the opening side of the conveying chute 111 can be used as the supporting surface 112. In this way, the fastener 6 can be horizontally placed horizontally on the conveying member 12 along its axis direction, that is, the head portion 61 of the fastener 6 is located in the conveying chute 111, and the rod portion 62 of the fastener 6 is located on one supporting surface 112, so that the fastener 6 can move in a rolling manner on the conveying member 12.

[0050] In another example, the conveying member 12 can also be a structure of two long strip rods. The two long strip rods are arranged in parallel, and the space between the two long strip rods forms a cavity for accommodating the rod portion 62 of the fastener 6. The surface of the head portion 61 of the fastener 6 connected to the rod portion 62 is abutted and supported on the two long strip rods, so that the fastener 6 is vertically suspended between the two long strip rods along its axis direction.

[0051] In the above embodiments, since the conveying structure 11 is arranged on the conveying member 12 and the conveying structure 11 is arranged in a structural form including a conveying chute 111 and a supporting surface 112, a part of the fastener 6 can be supported by the supporting surface 112 to facilitate the movement of the fastener 6 along the conveying structure 11. Another part of the fastener 6 can also be accommodated in the conveying chute 111 to limit the movement path and the supporting position of the fastener 6 on the conveying structure 11. Thus, at least a part of each fastener 6 can be in a determined position relative to the conveying member 12, which is beneficial to improving the accuracy of detecting the fastener 6 by the detecting device 2.

[0052] In some possible embodiments of the present application, as Figure 1 , Figure 2 and Figure 3 shown, the conveying device 1 further includes a conveying propulsion structure 13. The conveying propulsion structure 13 is arranged on the conveying member 12 and cooperates with the conveying chute 111 to form a conveying channel. The conveying propulsion structure 13 is used to apply a force towards the feed port 311 to the fastener 6 in the conveying channel.

[0053] In the embodiments of the present application, a conveying propulsion structure 13 can be arranged in the conveying device 1 to apply a force to the fastener 6 located on the conveying structure 11 through the conveying propulsion structure 13, so that a plurality of fasteners 6 sequentially move along the conveying structure 11 to the feed port 311.

[0054] Exemplarily, the conveying propulsion structure 13 can be arranged on the opening side of the conveying chute 111 on the conveying member 12, that is, the conveying propulsion structure 13 covers one side of the supporting surface 112 on the conveying member 12. For example, a part of the conveying propulsion structure 13 can be abutted against the edge of the supporting surface 112, or there is a gap with a certain distance between the conveying propulsion structure 13 and the supporting surface 112. Thus, a conveying channel is formed by enclosing the conveying propulsion structure 13 and the conveying structure 11, and the fastener 6 can move towards the feed port 311 from this conveying channel.

[0055] In another example, a part capable of applying a force towards the feed port 311 to the fastener 6 can be arranged in the conveying propulsion structure 13 to apply a force to the fastener 6, so that the fastener 6 moves towards the feed port 311 along the conveying channel in sequence under this force. For example, a motor with a lever can be arranged in the conveying propulsion structure 13, and the lever can be parallel to the supporting surface 112. The motor drives the lever to rotate at a preset frequency. Each time the lever rotates one circle, the fastener 6 can be advanced a certain distance along the conveying channel towards the feed port 311.

[0056] In the above embodiments, since the conveying and pushing structure 13 cooperates with the conveying chute 111 on the conveying member 12 to form a semi-closed conveying channel, the fasteners 6 can be completely located inside the conveying channel to shield the fasteners 6 through the conveying channel, which is beneficial to reducing the influence of the external environment on the fasteners 6. Moreover, a force towards the feed port 311 can be applied to the fasteners 6 through the conveying and pushing structure 13, so that the fasteners 6 can enter the feed port 311 in sequence, and then the fastener sorting device can continuously detect and convey the fasteners 6.

[0057] In some possible embodiments of the present application, as Figure 2 and Figure 3 shown, the conveying and pushing structure 13 includes a pressing member 131 and a first blowing channel 132. The pressing member 131 covers the conveying chute 111 to enclose and form a conveying channel; the first blowing channel 132 is arranged at one end of the pressing member 131 and / or the conveying member 12 away from the discharge port 312 and is communicated with the conveying channel, and the first blowing channel 132 is used for connecting with a first blowing air source.

[0058] In the embodiments of the present application, the pressing member 131 can be arranged on one side of the supporting surface 112 of the conveying member 12, and the pressing member 131 can be arranged in structures such as a long strip plate shape or a long strip rod shape. For example, if one end of the pressing member 131 away from the feed port 311 is rotatably connected to the conveying member 12, the conveying channel can be opened by rotating the pressing member 131 to facilitate the inspection and maintenance of the conveying device 1.

[0059] Exemplarily, the first blowing channel 132 can be arranged at one end of the pressing member 131 or the conveying member 12 away from the feed port 311, or the first blowing channel 132 can be arranged at one end of both the pressing member 131 and the conveying member 12 away from the feed port 311. The first blowing channel 132 can be a through hole penetrating the pressing member 131 and / or the conveying member 12. The through hole is communicated with the conveying channel and can be inclined towards the direction close to the feed port 311, that is, the end of the through hole communicated with the conveying channel is closer to the feed port 311 than the other end of the through hole. In this way, if the first blowing channel 132 is connected to the first blowing air source, air can be blown into the conveying channel through the first blowing channel 132 to apply a force towards the feed port 311 to the fasteners 6 through the air flow, so that the fasteners 6 slide or roll along the supporting surface 112 into the feed port 311.

[0060] In the above embodiments, since the pressing member 131 is covered on the conveying chute 111, a conveying channel can be formed by enclosing the pressing member 131 and the conveying chute 111. And a first blowing channel 132 is provided on the pressing member 131 and / or the conveying member 12, and the first blowing channel 132 can be connected to a first blowing air source, so that an air flow towards the feeding port 311 can be blown into the conveying channel, and the fastener 6 can move towards the feeding port 311 under the action of the air flow.

[0061] In some possible embodiments of the present application, as Figure 3 shown, the detection device 2 includes a first detection member 21. The first detection member 21 is arranged on the conveying device 1, and at least a part of the first detection member 21, or the transmission path of the first detection signal generated by the first detection member 21 is located in the conveying chute 111. In the vertical direction V perpendicular to the support surface 112, the distance between the first detection member 21 and the support surface 112 is greater than the length of the part of the fastener 6 that meets the specification requirements and is located in the conveying chute 111.

[0062] In the embodiments of the present application, the first detection member 21 can be arranged in the detection device 2 to detect the overlong fastener 63 with a length greater than the required specification fastener 6 through the first detection member 21.

[0063] Exemplarily, as Figure 3 shown, when the fastener 6 is vertically suspended in the conveying chute 111 along its axial direction, the first detection member 21 can be arranged on the conveying member 12. For example, the first detection member 21 is arranged on the groove wall of the conveying chute 111, and in the vertical direction V perpendicular to the support surface 112, the distance between the first detection member 21 and the support surface 112 can be made greater than the length of the part of the fastener 6 that meets the specification requirements and is located in the conveying chute 111, that is, the distance between the first detection member 21 and the support surface 112 is greater than the length of the rod portion 62 of the fastener 6 that meets the specification requirements. In this way, when the overlong fastener 63 passes through the first detection member 21, the rod portion 62 of the overlong fastener 63 can trigger the first detection member 21.

[0064] Exemplarily, the first detection member 21 can adopt a contact switch, and a part of the contact switch extends into the conveying chute 111. When the overlong fastener 63 passes through the contact switch, the contact switch can be touched to generate a corresponding detection signal. The first detection member 21 can also adopt a laser sensor, an ultrasonic sensor, an electromagnetic sensor, etc. The first detection signals such as light beams, sound waves or magnetic fields generated by the laser sensor, the ultrasonic sensor, and the electromagnetic sensor can be transmitted towards the inside of the conveying chute 111 and correspond to the free end of the rod portion 62 of the overlong fastener 63. Then, when the overlong fastener 63 passes through these sensors, these sensors can be triggered to generate corresponding detection signals.

[0065] In the above embodiments, since the first detection member 21 is disposed on the conveying device 1 and the distance between the first detection member 21 and the support surface 112 is greater than the length of the portion of the fastener 6 of the required specification located in the conveying chute 111, when the extra-long fastener 63 passes by the first detection member 21, the first detection member 21 can be triggered, so that the first detection member 21 can generate a corresponding detection signal, and thus the extra-long fastener 63 can be accurately detected.

[0066] In some possible embodiments of the present application, as Figure 3 shown, the detection device 2 further includes a second detection member 22 and a third detection member 23 both disposed on the conveying device 1. In the vertical direction V perpendicular to the support surface 112, the second detection member 22 is located on the side of the support surface 112 of the conveying device 1 away from the conveying chute 111 for detecting the portion of the fastener 6 supported on the support surface 112; at least a part of the third detection member 23, or the transmission path of the third detection signal generated by the third detection member 23 is located in the conveying chute 111. In the vertical direction V perpendicular to the support surface 112, there is a first distance between the third detection member 23 and the support surface 112, and the first distance is shorter than the length of the portion of the fastener 6 located in the conveying chute 111 by a preset distance.

[0067] In the embodiments of the present application, more detection members can be provided in the detection device 2 so that the fastener sorting device can detect more specifications of fasteners 6.

[0068] Exemplarily, as Figure 3 shown, the second detection member 22 can be disposed on the side of the support surface 112 of the conveying member 12 away from the conveying chute 111, that is, the second detection member 22 is disposed at the position where the head 61 of the fastener 6 on the conveying member 12 passes. In this way, all the fasteners 6 hanging vertically on the support surface 112 can trigger the second detection member 22.

[0069] Another example, as Figure 3As shown, a third detector 23 can be provided on the side wall of the chute 111 conveyed on the conveyor 12, and along the vertical direction V perpendicular to the support surface 112, a first distance can be provided between the third detector 23 and the support surface 112. The first distance can be set according to the length of the rod portion 62 of the fastener 6 of the required specification. For example, the first distance can be set to be 2 mm, 5 mm, etc. shorter than the length of the rod portion 62 of the fastener 6 of the required specification. In this way, when the fastener 6 of the required specification passes through the second detector 22 and the third detector 23, both the second detector 22 and the third detector 23 can be triggered. When the ultra-short fastener 64 shorter than the fastener 6 of the required specification passes through the second detector 22 and the third detector 23, only the second detector 22 can be triggered by the head 61 of the ultra-short fastener 64, and the third detector 23 will not be triggered by the rod portion 62 of the ultra-short fastener 64.

[0070] Among them, both the second detector 22 and the third detector 23 can adopt devices capable of generating detection signals, such as contact switches, laser sensors, ultrasonic sensors, and electromagnetic sensors.

[0071] In the above embodiment, since the second detector 22 and the third detector 23 are provided on the conveying device 1, and the second detector 22 can detect the part of the fastener 6 supported on the support surface 112, and a first distance is provided between the third detector 23 and the support surface 112, all the fasteners 6 conveyed through the conveying channel can be detected by the second detector 22, and the ultra-short fasteners 6 with a length shorter than that of the required fastener 6 can be detected according to whether the third detector 23 is triggered, so that the application scenarios of the fastener sorting device can be increased.

[0072] In some possible embodiments of the present application, as Figure 3 shown, the detection device 2 includes a weighing scale 24. The weighing scale 24 is provided on the support surface 112. During the process of the fastener 6 moving towards the feed port 311 through the support surface 112, the weighing scale 24 is triggered by the fastener 6, and the weighing scale 24 is used to detect the weight of the fastener 6.

[0073] In the embodiments of the present application, since the weights of fasteners 6 of different specifications are different, it is possible to determine whether the fastener 6 meets the usage requirements by detecting the weight of each fastener 6.

[0074] Exemplarily, a weighing meter 24 can be provided on the support surface 112 located on the conveying member 12 to detect the weight of each fastener 6 passing through the support surface 112 by the weighing meter 24. If the difference between the weight of the currently detected fastener 6 and the weight of the required fastener 6 exceeds a preset threshold, it can be determined that the currently detected fastener 6 may be a fastener 6 with incorrect specifications. For example, the preset threshold can be values such as five percent or two percent of the weight of the required fastener 6. Among them, the weighing meter 24 can adopt a resistive weighing meter 24, a capacitive weighing meter 24, etc.

[0075] In the above embodiment, since the detection device 2 includes a weighing meter 24, it is possible to determine whether the fastener 6 is a fastener 6 of the required specification according to the weight of the fastener 6 detected by the weighing meter 24, which can increase the detection methods of the fastener sorting device and can be applicable to the situation where there are multiple fasteners 6 with lengths not meeting the specification requirements at the same time, which is beneficial to improving the applicability of the fastener sorting device.

[0076] In some possible embodiments of the present application, such as Figure 2 and Figure 3 As shown, a part of the fastener 6 includes a head 61 for abutting against the connected part, and another part of the fastener 6 includes a rod portion 62 fixedly connected to the connected part.

[0077] In the embodiments of the present application, the fastener 6 can include at least one of the following: screws, bolts, rivets, etc. The fastener 6 generally includes a head 61 and a rod portion 62. For example, in the case where the fastener 6 is a screw or a bolt, the heads 61 of the screw and the bolt are generally hexagonal prisms, or cylindrical shapes with internal hexagonal holes, flat slots, cross slots, etc., so as to facilitate the connection of the screwdriver to the head 61 of the screw or the bolt. The rod portions 62 of the screw and the bolt generally have external threads. In the case where the fastener 6 is a rivet, the head 61 of the rivet is generally approximately hemispherical, and the rod portion 62 of the rivet is a smooth cylindrical shape. And the diameter of the head 61 of the fastener 6 is greater than the diameter of the rod portion 62, so that the head 61 of the fastener 6 can be abutted against the surface of the connected part, and the rod portion 62 of the fastener 6 can be located in the threaded hole or through hole on the connected part, thereby facilitating the connection of the fastener 6 to the connected part and also facilitating the fixation of the fastener 6 to the connected part. The head 61 and / or the rod portion 62 of the fastener 6 can also be placed at positions corresponding to the conveying structure 11, which is convenient for positioning the fastener 6 on the conveying structure 11, so that the fastener 6 can be placed at an accurate position on the fastener sorting device, and further each fastener 6 can move on the conveying device 1 along a determined route.

[0078] In some possible embodiments of the present application, a detection signal is associated with a fastener 6 of a structural type, and each discharge port 312 is used to convey at least one structural type of fastener 6.

[0079] In the embodiments of the present application, as Figure 3 shown, according to the application scenario of the fastener sorting device, the detection device 2 can be electrically connected to the shunting device 3 to control the movement of the shunting device 3, so as to realize the detection and shunting of the fasteners 6.

[0080] Exemplarily, the first detection member 21 and the third detection member 23 can both be associated with the same discharge port 312. In this way, when the first detection member 21 and / or the third detection member 23 is triggered to generate a detection signal, the shunting device 3 can be controlled to drive the corresponding fasteners 6 to move towards the same discharge port 312, so that the ultra-long fasteners 63 and the ultra-short fasteners 64 can both be conveyed from the same discharge port 312 to the corresponding positions. And the second detection member 22 and the third detection member 23 are both associated with another discharge port 312. When the second detection member 22 and the third detection member 23 are simultaneously triggered to generate a detection signal, the shunting device 3 can be controlled to drive the corresponding fasteners 6 to move towards another discharge port 312, so that the fasteners 6 of the required specifications can be conveyed to the corresponding positions. In this way, the detection and shunting of fasteners 6 of different specifications can be realized.

[0081] In some possible embodiments of the present application, referring to Figure 6 and Figure 7 , Figure 6 is a schematic exploded view of the shunting assembly in the fastener sorting device provided by the present application, Figure 7 is a schematic top view of the shunting device in the fastener sorting device provided by the present application Figure 1 . As Figure 4 , Figure 6 and Figure 7 shown, the shunting device 3 includes a shunting base 31, a shunting assembly 32 and a driving member 33; the shunting base 31 is provided with a feed port 311 and at least two discharge ports 312; the shunting assembly 32 is movably arranged on the shunting base 31, and the shunting assembly 32 is provided with a shunting channel 321; the driving member 33 is installed on the shunting base 31, the driving member 33 is connected to the shunting assembly 32, and the driving member 33 can drive the shunting assembly 32 to move relative to the shunting base 31, so that one end of the shunting channel 321 is communicated with the feed port 311, or the other end of the shunting channel 321 is communicated with one of the discharge ports 312.

[0082] In the embodiments of the present application, the shunting base 31 is used to carry and install other parts in the shunting device 3, and the feed port 311 and the discharge ports 312 can both be arranged on the shunting base 31. As Figure 1 and Figure 4As shown, the shunt base 31 can be set as a closed box-like structure, and some parts in the shunt device 3 can be installed inside the box-like shunt base 31. For example, a feed inlet 311 is provided on the top wall of the box-like shunt base 31, and at least two discharge outlets 312 are provided on the bottom wall of the box-like shunt base 31.

[0083] In the embodiment of the present application, a shunt component 32 can be installed in the shunt base 31 to convey the fastener 6 from the feed inlet 311 to the corresponding discharge outlet 312 through the shunt component 32. For example, the shunt component 32 can be movably installed in the shunt base 31 along the connection direction of the two discharge outlets 312. As Figure 6 shown, a shunt channel 321 can be provided on the shunt component 32, and the extending direction of the shunt channel 321 is parallel or approximately parallel to the direction from the feed inlet 311 towards the discharge outlet 312. For example, the shunt channel 321 can be an approximately U-shaped groove, and the U-shaped groove penetrates through the shunt component 32.

[0084] In the embodiment of the present application, a driving member 33 can be provided on the shunt base 31, and the output part 331 of the driving member 33 is fixedly connected to the shunt component 32 to drive the shunt component 32 to move relative to the shunt base 31 through the driving member 33. For example, the driving member 33 can adopt a three-position cylinder, that is, the piston rod of the three-position cylinder can move to three positions; the driving member 33 can also adopt a motor, a gear and a rack. The embodiment of the present application does not limit the type of the driving member 33. In this way, as Figure 7 shown, one end of the shunt channel 321 can be communicated with the feed inlet 311, or the shunt component 32 can move in the shunt base 31 so that the other end of the shunt channel 321 is communicated with a discharge outlet 312.

[0085] In the above embodiment, since the shunt component 32 is movably arranged on the shunt base 31 and the shunt channel 321 is provided on the shunt component 32, the shunt component 32 can be driven to move relative to the shunt base 31 through the driving member 33, so that the shunt channel 321 can be communicated with the feed inlet 311 on the shunt base 31. At this time, the fastener 6 can enter the shunt channel 321 through the feed inlet 311. It is also possible to communicate the shunt channel 321 with a discharge outlet 312 on the shunt base 31. At this time, the fastener 6 can be conveyed from the corresponding discharge outlet 312 to the corresponding position, so as to realize the shunt of the fastener 6.

[0086] In some possible embodiments of the present application, referring to Figure 8 and Figure 9 , Figure 8 and Figure 9 show the top view structural schematic diagrams of different states of the shunt device in the fastener sorting equipment provided by the present application. As Figure 6As shown in the figure, the flow splitting component 32 includes a flow splitting member 322 and a limiting member 323. The flow splitting member 322 is slidably arranged on the flow splitting base body 31 along the first direction F, and a flow splitting channel 321 is arranged on the flow splitting member 322. The limiting member 323 is slidably arranged on the flow splitting member 322 along the second direction S, and the limiting member 323 is located at a position adjacent to the feed inlet 311. One end of the limiting member 323 close to the feed inlet 311 has a limiting groove 3231, and the limiting groove 3231 is respectively communicated with the feed inlet 311 and the flow splitting channel 321. The limiting groove 3231 can accommodate the other part of the fastening member 6, and the limiting member 323 is used to limit the movement of the fastening member 6 into the flow splitting channel 321. The first direction F is the arrangement direction of at least two discharge ports 312, and there is a first included angle between the second direction S and the first direction F.

[0087] In the embodiment of the present application, the flow splitting member 322 may be a block-shaped structure, and the flow splitting channel 321 may be arranged on the flow splitting member 322. And the flow splitting member 322 can be slidably arranged on the flow splitting base body 31 along the first direction F. The first direction F is the arrangement direction of two discharge ports 312 on the flow splitting base body 31.

[0088] Exemplarily, as Figure 7 shown, a guide rail 314 may be arranged on the flow splitting base body 31, and the guide rail 314 extends along the first direction F. As Figure 6 shown, a flow splitting sliding groove 3222 matching the guide rail 314 may be arranged on the flow splitting member 322. In this way, the flow splitting member 322 can be slidably arranged on the flow splitting base body 31 along the first direction F through the matching guide rail 314 and flow splitting sliding groove 3222.

[0089] In the embodiment of the present application, a limiting member 323 may be arranged on the flow splitting member 322 to enable the fastening member 6 to completely move into the flow splitting channel 321 at a specific position through the limiting member 323.

[0090] Exemplarily, a limiting sliding groove 3221 may be arranged on the surface of the flow splitting member 322 perpendicular to the flow splitting channel 321, and the limiting sliding groove 3221 extends along the second direction S. For example, the first included angle between the second direction S and the first direction F may be 90 degrees, or an angle close to 90 degrees, or an included angle of other angles. The limiting member 323 may be arranged as a sheet-like structure and be matched with the limiting sliding groove 3221, that is, the limiting member 323 can be slidably accommodated in the limiting sliding groove 3221.

[0091] In another example, a limiting groove 3231 can be provided at one end of the limiting member 323 close to the diversion channel 321. The limiting groove 3231 extends along the second direction S. For example, the limiting groove 3231 can be a groove approximately in the shape of a U. Among them, the width of the limiting groove 3231 is greater than the diameter of the rod portion 62 of the fastener 6 and less than the diameter of the head portion 61 of the fastener 6. In this way, the surface of the limiting member 323 away from the diversion member 322 is in the same plane as the supporting surface 112 on the conveying member 12, as Figure 7 shown, when the diversion channel 321 of the diversion member 322 is aligned with the feed port 311 (the feed port 311 is always aligned with and communicated with the conveying chute 111), the limiting groove 3231 is communicated with the feed port 311 and is communicated with the diversion channel 321. Then, the rod portion 62 of the fastener 6 can enter the limiting groove 3231 and the diversion channel 321 from the conveying channel, and the head portion 61 of the fastener 6 is supported on the edge of the limiting groove 3231 on the limiting member 323, so as to limit the fastener 6 from completely falling into the diversion channel 321. As Figure 8 and Figure 9 shown, when the diversion member 322 moves to a position where the diversion channel 321 is communicated with one discharge port 312, the limiting member 323 moves to a position away from the diversion channel 321, and the restriction on the fastener 6 is released.

[0092] In the above embodiment, since the diversion member 322 is slidably arranged on the diversion base body 31 along the first direction F, the diversion channel 321 on the diversion member 322 can be communicated with the feed port 311 or the discharge port 312, so that the fastener 6 located in the diversion channel 321 can be driven by the diversion member 322 to the corresponding discharge port 312. And a limiting member 323 is slidably arranged on the diversion member 322, so that the limiting groove 3231 on the limiting member 323 is communicated with the feed port 311 and the diversion channel 321. During the process of the fastener 6 moving from the conveying chute 111 to the feed port 311, the limiting member 323 can limit the fastener 6 from directly falling into the diversion channel 321. At the same time, the limiting member 323 is slidably arranged on the limiting member 323 along the second direction S, so that during the process of the diversion member 322 moving along the first direction F towards the direction close to the discharge port 312, the limiting member 323 can move along the second direction S towards the direction away from the diversion channel 321, thereby releasing the restriction on the fastener 6, and enabling the fastener 6 to completely fall into the diversion channel 321 and enter the corresponding discharge port 312. And it can reduce the risk that during the process of the diversion member 322 sliding relative to the diversion base body 31, the fastener 6 falls into the diversion channel 321 and gets stuck between the diversion member 322 and the diversion base body 31, resulting in jamming when the diversion member 322 slides relative to the diversion base body 31.

[0093] In some possible embodiments of the present application, such as Figure 1 、 Figure 6and Figure 10 As shown in Figure 10 , one of the shunt base body 31 and the limiting member 323 is provided with a guiding groove 313, and the other is provided with a guiding post 3232 that matches the guiding groove 313. The extending direction of the guiding groove 313 forms an angle with both the first direction F and the second direction S; during the movement of the shunt member 322 along the first direction F, the limiting member 323 moves along the second direction S away from the feeding port 311 under the guidance of the guiding groove 313 and the guiding post 3232, so as to separate from the fastener 6.

[0094] In the embodiment of the present application, by providing a matching guiding groove 313 and guiding post 3232 on the shunt base body 31 and the limiting member 323, during the movement of the shunt member 322 along the first direction F, the limiting member 323 can be made to move along the second direction S.

[0095] Exemplarily, as Figure 1 shown, a guiding groove 313 can be provided on the wall body of the shunt base body 31 adjacent to the limiting member 323. For example, the guiding groove 313 can be set as a chute approximately in the shape of a V. The two ends of the V-shaped chute are far from the shunt channel 321, and the middle part of the V-shaped chute is close to the shunt channel 321. And both chute parts of the V-shaped chute form an angle with the first direction F and the second direction S. For example, this angle can be 45 degrees. Correspondingly, as Figure 1 and Figure 6 shown, a guiding post 3232 that matches the guiding groove 313 can be provided on the limiting member 323, and the guiding post 3232 is inserted into the guiding groove 313.

[0096] Another example, as Figure 9 shown, a guiding groove 313 can also be provided on the surface of the limiting member 323 close to the shunt base body 31. For example, the guiding groove 313 can be set as a chute approximately in the shape of a V. The two ends of the V-shaped chute are close to the limiting groove 3231, and the middle part of the V-shaped chute is far from the limiting groove 3231. And both chute parts of the V-shaped chute form an angle with the first direction F and the second direction S. For example, this angle can be 45 degrees. Correspondingly, a guiding post 3232 that matches the guiding groove 313 can be provided on the surface of the shunt base body 31 close to the limiting member 323, and the guiding post 3232 is inserted into the guiding groove 313.

[0097] In the above embodiments, since the diversion base 31 and the limiting member 323 are respectively provided with matching guide grooves 313 and guide posts 3232, during the movement of the diversion member 322 in the first direction F, under the restriction and guidance of the guide grooves 313 and the guide posts 3232, the limiting member 323 can move relative to the diversion member 322 in the second direction S, so that the limiting member 323 can move away from or close to the feed inlet 311, and further the restriction on the fastener 6 can be released, or it can be in a position where the fastener 6 can be restricted from falling into the diversion channel 321.

[0098] In some possible embodiments of the present application, as Figure 4 shown, the fastener sorting device further includes a feeding member 4 having a feeding channel. A feeding member 4 is connected to each discharge port 312. The feeding channel is matched with the fastener 6 and communicated with the discharge port 312. The feeding member 4 can extend to the material using position; a second blowing channel 5 is provided at a position of the feeding member 4 close to the discharge port 312. One end of the second blowing channel 5 is communicated with the feeding channel, and the other end is connected to a second blowing air source.

[0099] In the embodiments of the present application, the feeding member 4 can be provided on the diversion base 31 to convey the fastener 6 to the material using position through the feeding member 4.

[0100] Exemplarily, a feeding member 4 can be provided for each discharge port 312 on the diversion base 31. The feeding member 4 can adopt a pipe matched with the fastener 6, and the pipe is communicated with the discharge port 312. For example, the inner diameter of the feeding member 4 is slightly larger than the diameter of the head 61 of the fastener 6, which can reduce the problem that the fastener 6 is stuck in the feeding member 4.

[0101] In another example, a second blowing channel 5 can be provided on the feeding member 4. For example, a through hole can be provided on the pipe wall of the feeding member 4, and the through hole is used as the second blowing channel 5. The second blowing channel 5 can extend obliquely away from the discharge port 312, that is, the end of the second blowing channel 5 communicated with the inside of the pipe serving as the feeding member 4 is farther away from the discharge port 312 than the other end of the second blowing channel 5. In this way, the second blowing channel 5 can be connected to the second blowing air source, so as to blow air into the feeding member 4 to drive the fastener 6 to move in the feeding member 4 towards the using position by the air flow. Among them, the second blowing air source and the first blowing air source can be the same blowing air source or two independent blowing air sources, and the embodiments of the present application do not limit this.

[0102] In the above embodiments, since the feeding member 4 is provided at the discharge port 312, the feeding member 4 can be extended to the material using position, so as to convey the fasteners 6 diverted from the discharge port 312 to the material using position. At the same time, a second air blowing channel 5 is provided on the feeding member 4, and gas can be blown into the feeding member 4 through the second air blowing channel 5, so that the fasteners 6 can be driven by the air flow to move rapidly in the feeding member 4, which is beneficial to improving the conveying efficiency of the fasteners 6.

[0103] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered within the scope of the description of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
