[0037] The pole-mounted switch production line provided in an embodiment of the present invention includes a conveyor line 700, an assembly station, a running-in station, a testing station and a unloading station. The conveyor line 700 is used to convey the pole-mounted switch 900. The conveyor line 700 includes a conveying positioning unit 710, a lifting unit 720 and a first transfer unit 730. The first transfer unit 730 is used to transfer the pole-mounted switch 900. The assembly station includes an assembly workstation 100 and a fastening workstation 200. The running-in station is located downstream of the assembly station. The running-in station includes a running-in workstation 300. The testing station is located downstream of the running-in station. The testing station includes a testing workstation 400. The unloading station is located downstream of the testing station.

[0038] The assembly station, running-in station, testing station and unloading station are arranged in sequence. During the production process of the pole switch 900, the material passes through the assembly station, running-in station, testing station and unloading station in sequence along the conveyor line 700. The material is assembled into the pole switch 900 at the assembly station, the pole switch 900 is subjected to a running-in test at the running-in station, the pole switch 900 is subjected to a performance test at the testing station, and the pole switch 900 is unloaded at the unloading station, thereby completing the production process of the pole switch 900.

[0039] The pole switch production line provided in the embodiment of the present invention can realize the assembly, running-in and testing processes of the pole switches by setting an assembly station, a running-in station, a testing station and a unloading station, thereby improving the automation level of the pole switch production. The conveying and positioning unit 710 and the lifting unit 720 can stop the movement of the pole switch 900, and the first transfer unit 730 can transfer the pole switch 900 outside the conveyor line, thereby improving the automation level of the positioning and transportation of the pole switch 900. The pole switch production line can improve the automation level of the pole switch production process.

[0040] According to some embodiments of the present invention, the pole switch production line includes a tooling pallet 800, and the tooling pallet 800 is used to carry the pole switch 900. The pole switch 900 moves on the pole switch production line through the tooling pallet 800.

[0041] It can be understood that the pole switch 900 includes components such as a pole 910 and a box body 920. The pole switch 900 is gradually assembled on the tooling tray 800 as the production process progresses. Therefore, the pole switch 900 referred to in the present invention refers to both a finished pole switch 900 and a pole switch 900 in a semi-finished state.

[0042] There are two ways to place the pole switch 900 on the tooling tray 800, one is that the pole 910 is located at the bottom, and the other is that the box 920 is located at the bottom. The tooling tray 800 includes a first positioning block 830 and a second positioning block. The first positioning block 830 and the second positioning block are used to position the pole switch 900 when the box 920 is located at the bottom. The tooling tray 800 includes a third positioning block 850. The third positioning block 850 is formed in a shape that matches the pole 910. The third positioning block 850 is used to position the pole switch 900 when the pole 910 is located at the bottom. For example, Figure 4 As shown, the first positioning block 830 and the second positioning block can contact the side wall of the box body 920 to locate the position of the box body 920, and the third positioning block 850 has a groove, and the pole 910 can be embedded in the groove to locate the pole 910.

[0043] The tooling pallet 800 is provided with a positioning groove 810 , which includes a guide surface which is inclined. The positioning groove 810 is adapted to the conveying positioning unit 710 . The tooling pallet 800 includes a pallet pressure rod 820 which is used to fix the switch 900 on the column.

[0044] The conveying and positioning unit 710 limits the movement of the pole switch 900 so as to facilitate the operation of the pole switch 900 on the conveying line 700. According to some embodiments of the present invention, the conveying and positioning unit 710 limits the pole switch 900 by limiting the tooling tray 800.

[0045] In some embodiments, the conveying and positioning unit 710 includes a blocking block 711 and a blocking block mounting seat 712, and the blocking block 711 is movably disposed on the blocking block mounting seat 712. The blocking block 711 can move by moving or swinging, for example Figure 7 , Figure 8 As shown in the embodiment, the blocking block 711 is hinged on the blocking block mounting seat 712, and the blocking block mounting seat 712 is also provided with a blocking block driver 713 and a torsion spring. The blocking block driver 713 pushes the blocking block 711 to rotate to disengage from the tooling pallet 800, and the torsion spring resets the blocking block 711.

[0046] In some embodiments, the positioning groove 810 is adapted to the blocking block 711, and the blocking block 711 is inserted into the positioning groove 810, thereby improving the positioning effect of the tooling pallet 800. The interaction between the guide surface and the blocking block 711 can adjust the position of the tooling pallet 800 to ensure accurate positioning.

[0047] In some embodiments, the blocking block 711 includes a roller. The roller can reduce the friction between the blocking block 711 and the tooling tray 800, and reduce the damage of the blocking block 711 to the tooling tray 800. For example, when the torsion spring resets the blocking block 711, the blocking block 711 contacts the bottom of the tooling tray 800, and the use of the roller can convert the sliding friction during the contact into rolling friction, thereby avoiding obstruction of the normal transportation of the tooling tray 800 and avoiding damage to the tooling tray.

[0048] The lifting unit 720 can further limit the column switch 900 on the conveyor line 700. According to some embodiments of the present invention, the lifting unit 720 limits the column switch 900 by limiting the tooling pallet 800. It can be understood that the tooling pallet 800 blocked by the conveying positioning unit 710 still has a tendency to move forward due to the force of the conveyor line 700, which may cause the tooling pallet 800 to shake and affect the accuracy of positioning. The lifting unit 720 lifts the tooling pallet 800 to separate the tooling pallet 800 from the conveying part of the conveyor line 700, thereby ensuring the stability of the positioning of the tooling pallet 800 and further improving the accuracy of positioning.

[0049] In some embodiments, the lifting unit 720 includes a lifting pallet 721, a lifting mounting plate 722 and a lifting driver 723. The lifting driver 723 is disposed on the lifting mounting plate 722. The lifting pallet 721 is disposed on the lifting driver 723. The lifting pallet 721 lifts the tooling pallet 800.

[0050] In some embodiments, the lifting unit 720 further includes a lifting guide shaft 724, and the lifting guide shaft 724 guides the lifting support plate 721. Figure 7 , Figure 8 As shown in the embodiment, the lifting installation plate 722 is installed on the conveyor line 700, and two lifting drivers 723 are respectively arranged on the front and rear sides of the lifting installation plate 722. The lifting unit 720 also includes a lifting guide seat 725, which is arranged on the left and right sides of the lifting installation plate 722. The lifting guide shaft 724 is arranged on the lifting support plate 721, and the lifting guide shaft 724 is inserted in the lifting guide seat 725. The lifting guide seat 725 and the lifting guide shaft 724 guide the movement of the lifting support plate 721. The two lifting drivers 723 make the lifting support plate 721 more stressed.

[0051] In some embodiments, a pallet positioning portion 726 is provided on the lifting support plate 721, and the pallet positioning portion 726 is adapted to the tooling pallet 800, and the pallet positioning portion 726 positions the tooling pallet 800. Figure 8In the embodiment, the tray positioning portion 726 uses multiple positioning pins, and the tooling pallet 800 is provided with pin holes that are compatible with the positioning pins. The positioning pins are inserted into the pin holes to accurately position the tooling pallet 800. The head of the positioning pin has a chamfer to facilitate the matching of the positioning pin and the pin hole.

[0052] Of course, the lifting guide shaft 724 and the pallet positioning portion 726 may also adopt other specific designs. For example, the lifting guide shaft 724 may be set on the lifting mounting plate 722, and the lifting guide shaft 724 may be inserted on the lifting support plate 721. For example, the pallet positioning portion 726 may adopt a pin hole.

[0053] The first transfer unit 730 transfers the column switch 900 outside the conveyor line 700. According to some embodiments of the present invention, the first transfer unit 730 transfers the column switch 900 by conveying the tooling tray 800. It is understandable that the number of the first transfer unit 730 can be one or more. In some embodiments, the conveyor line 700 has a plurality of first transfer units 730, one of which is located on the conveyor line 700 and matches the running-in station, one of which is located on the conveyor line 700 and matches the detection station, and the first transfer unit 730 transfers the column switch 900 to the running-in station and the detection station.

[0054] In some embodiments, the first transfer unit 730 includes a first active roller 731, and a switch 900 is placed on a conveying column through the rotation of the first active roller 731. In some embodiments, the first transfer unit 730 includes a first mounting platform 732 and a first lifting platform 733, wherein the first lifting platform 733 is disposed on the first mounting platform 732, and the first active roller 731 is disposed on the first lifting platform 733. When transfer is required, the first lifting platform 733 rises to make the tooling pallet 800 separate from the conveying route of the conveyor line 700, and the first active roller 731 moves to transfer the tooling pallet 800. When transfer is not required, the first lifting platform 733 descends to make the height of the first active roller 731 lower than the tooling pallet 800 moving along the conveying route of the conveyor line 700, and the tooling pallet 800 can pass through the first transfer unit 730 normally.

[0055] In some embodiments, the first mounting platform 732 is provided with a first driver 734 and a first guide seat 735, the first lifting platform 733 is provided on the first driver 734, and the first lifting platform 733 is provided with a first guide shaft 736, and the first guide shaft 736 is adapted to the first guide seat 735. The first guide shaft 736 can guide the lifting of the first lifting platform 733, ensuring the smooth lifting and the stable posture of the first lifting platform 733. The first guide shaft 736 can also be provided in other ways, such as exchanging the installation positions of the first guide shaft 736 and the first guide seat 735.

[0056] According to some embodiments of the present invention, the assembly workstation 100 includes a first assembly module, a first feeding module and a pre-processing module, the first assembly module includes a first assembly robot 110, the first feeding module is used to provide a pole 910 and a box 920, the pre-processing module is used to provide a sealing ring 930, the pre-processing module includes a feeding unit, a gluing unit and a pull rod guiding unit, the feeding unit includes a loading component and a suction component. The gluing unit includes a gluing head 138.

[0057] When in use, the first assembly robot 110 obtains the pole 910 from the first feeding module, the first assembly robot 110 moves to the pre-processing module, the feeding unit installs the sealing ring 930 on the pole 910, the gluing unit applies glue on the pole 910, the first assembly robot 110 loads the pole 910, and the first assembly robot 110 obtains the box 920 and installs the box 920 on the pole 910. In the installation link of the sealing ring 930, the suction component sucks the sealing ring 930 from the loading component, and then transfers the sealing ring 930 to the pole 910. By setting the first assembly robot 110, the feeding unit and the gluing unit, the assembly workstation 100 can easily complete the installation process of the pole 910, the box 920 and the sealing ring 930, thereby improving the automation level and assembly efficiency of the pole switch assembly process. At this time, the positioning of the tooling tray 800 is achieved by the cooperation of the conveying and positioning unit 710 and the lifting unit 720.

[0058] According to some embodiments of the present invention, the loading assembly includes a barrel 132 and a feeding structure 133, the barrel 132 is adapted to the feeding structure 133, the sealing ring 930 is stacked and placed on the barrel 132 along the axis direction of the barrel 132, and the feeding structure 133 can move along the axis direction of the barrel 132 to push the sealing ring 930. The feeding structure 133 can continuously push out the sealing ring 930 placed on the barrel 132 so that the suction assembly can suck. For example, Figure 3 As shown in the embodiment, the feeding structure 133 is sleeved on the barrel 132, and the feeding structure 133 is connected to the screw for transmission. The screw can drive the feeding structure to move along the axis of the barrel 132. The sealing ring 930 is sleeved on the barrel 132, and the feeding structure 133 supports the sealing ring 930. The feeding structure 133 continuously lifts the sealing ring 930 so that the suction component can be sucked.

[0059] In some embodiments, the loading assembly includes a carrier 131, which can rotate along its own rotation axis. The carrier 131 is provided with a plurality of barrels 132 and a plurality of feeding structures 133 arranged in an array with the rotation axis as the center. After the sealing ring 930 on the current barrel 132 is supplied, the carrier 131 can be rotated to switch between different barrels 132, so that the fully loaded barrel 132 is transferred to the position corresponding to the suction assembly to continue to supply the sealing ring 930, eliminating the step of stopping the machine for loading, and improving the automation level and assembly efficiency of the column switch assembly. The empty barrel 132 is in a non-working state at this time, and the sealing ring 930 can be reloaded on the barrel 132 at this time, and the loading will not affect the normal operation of the assembly workstation 100.

[0060] In some embodiments, the loading assembly includes a positioning post 134, and the carrier 131 is provided with a positioning hole adapted to the positioning post 134, and the positioning post 134 positions the carrier 131. The positioning of the carrier 131 by the matching relationship between the positioning hole and the positioning post 134 can ensure that the stop position of the barrel 132 does not deviate, and ensure the normal absorption of the absorption assembly.

[0061] Of course, in addition to rotating the carrier 131 to switch the barrel 132, other specific methods can also be used to switch the barrel 132. For example, different barrels 132 can be switched by moving the carrier 131, or after detecting that the current barrel 132 is fully supplied, the suction component is controlled to move to the fully loaded barrel 132 to take in air and take out materials.

[0062] According to some embodiments of the present invention, the suction assembly includes a suction head 135, and the suction head 135 is provided with at least one air hole, and the suction head 135 is used to suck the sealing ring 930. Figure 5 As shown, the suction head 135 is cylindrical in shape, and a plurality of air holes are arranged in an array below the suction head 135. The positions of the air holes are adapted to the specifications of the sealing ring 930, and the air holes are connected to the external negative pressure generating device. The suction head 135 is moved so that the air holes are attached to the sealing ring 930, and the sealing ring 930 is sucked by the negative pressure. The suction head 135 is moved to a position corresponding to the first assembly robot 110, and the sealing ring 930 is released so that the sealing ring 930 is transferred to the pole 910.

[0063] It is understandable that the movement of the suction head 135 can be driven by a common driving structure, such as a conveyor belt, a driving cylinder, a linear guide rail, etc.

[0064] According to some embodiments of the present invention, the preprocessing module includes a rod alignment unit, which includes a first alignment structure and a second alignment structure. The first alignment structure and the second alignment structure can be relatively close to locate the position of the rod 911 of the pole 910.

[0065] It is understandable that the pole 910 includes a pull rod 911, and the pull rod 911 needs to be inserted into the box body 920 when the pole 910 is combined with the box body 920. If the position of the pull rod 911 is skewed, the assembly may fail. The position of the pull rod 911 is adjusted by the pull rod guiding unit to ensure smooth assembly. In some embodiments, the first guiding structure and the second guiding structure are symmetrically arranged on the driving cylinder, and the driving cylinder can drive the first guiding structure and the second guiding structure to move toward each other to clamp and guide the pull rod 911. The first guiding structure and the second guiding structure are provided with V-shaped grooves so that the pull rod can be positioned. The first guiding structure and the second guiding structure are also provided with reinforcing ribs.

[0066] According to some embodiments of the present invention, the first assembly robot 110 includes a robot arm 111, a pole clamp 112 and a box clamp 113, wherein the pole clamp 112 is detachably mounted on the robot arm 111, and the box clamp 113 is detachably mounted on the robot arm 111. The first assembly robot 110 can switch between the pole clamp 112 and the box clamp 113. The first assembly robot 110 first uses the pole clamp 112 to carry and operate the pole 910, and then switches to the box clamp 113 to grab the box 920 and assemble the box 920 onto the pole 910. By setting the switchable pole clamp 112 and the box clamp 113, the first assembly robot 110 can be fully utilized, avoiding setting too many first assembly robots 110, and reducing the cost and complexity of the assembly workstation 100. In some embodiments, the pole clamp 112 and the box clamp 113 can be mounted on the robot arm 111 through a quick-change disk.

[0067] According to some embodiments of the present invention, the first feeding module includes a first track 122 and a first trolley 121. The first trolley 121 is disposed on the first track 122. The first trolley 121 can move along the first track 122. The first trolley 121 is used to carry the pole 910 and the box 920. Figure 2 As shown, the first feeding module is provided with a plurality of first carts 121, and the first carts 121 are provided with material trays, wherein a part of the first carts 121 carry poles 910, and another part of the first carts 121 carry boxes 920, and the fully loaded first carts 121 approach the first assembly module to feed materials to the first assembly robot 110, and the unloaded first carts 121 are away from the first assembly module for reloading. In some embodiments, guardrails are also provided to protect the assembly workstation 100.

[0068] In some embodiments, the first track 122 is installed with a leveling pad to ensure smooth operation of the first trolley 121. Specifically, the first track 122 is installed on the ground, and a number of leveling pads are placed between the first track 122 and the ground to adjust the level of the first track 122. The edge of the first trolley 121 is designed with a positioning edge, which is used to position the material tray, thereby ensuring the position accuracy of the material tray.
