[0015] Working principle: Place the various parts of the electric wheelchair on the left and right sides of the work platform. Then, start the electric slide to drive the robotic arm to pick up the workpiece and place it on the processing table. At this time, the cross slide will adjust and switch the components to weld or screw the workpiece on the processing table. After welding is completed, the robotic arm will pick up the welded workpiece and place it on the unloading box for unloading. At the same time, after all the workpieces on the work platform are welded, the operator can put the whole workpieces on both sides of the unloading box back on the work platform for screw splicing. This facilitates the welding and splicing of workpieces.

[0016] This invention provides a welding, assembly, and positioning platform for an electric wheelchair frame. It offers the following advantages: 1. This invention allows for the placement of workpieces on a work platform, where an electric slide controls a robotic arm to clamp the workpieces onto a processing table for processing. At this point, the cross slide controls a switching component to move to the appropriate position for welding. After welding, the workpieces are unloaded through a feeding box and then placed back onto the work platform for assembly by the switching component. This facilitates the welding and assembly of electric wheelchair frames, thereby improving work efficiency.

[0017] 2. In this invention, the first electric push rod pushes the control console to fit against the work platform. At this time, the base will enter the positioning hole, and the first elastic element will push the positioning column out. When the workpiece is placed on the work platform, it will press down some of the positioning columns. The positioning columns that are not pressed down will detect the workpiece data through the first infrared sensor and transmit it to the terminal through the control console. Moreover, the positioning columns that are not pressed down will position the workpiece. It can detect the values ​​of each workpiece in real time, so as to facilitate the precise picking up of the robotic arm.

[0018] 3. This invention uses a servo motor to drive the hollow column to rotate, thereby welding and clamping workpieces at different angles. The second electric push rod is activated to drive the guide column to connect with the first adjusting ring, so that the first adjusting ring drives the connecting rod and the arc plate to slide synchronously. This allows the welding head and the laser sensor to adjust synchronously, ensuring that the welding head is always in contact with the workpiece, thereby improving the welding accuracy. The laser sensor can monitor the welding and docking accuracy of the equipment.

[0019] 4. In this invention, the guide post drives the second adjusting ring to slide, which causes the right-angle rod to drive the second clamping plate and the first clamping plate to slide synchronously. At this time, the second clamping plate and the first clamping plate are connected, and the second adjusting ring is attracted by the second magnetic ring, which can achieve a stable clamping effect. The drive motor drives the cross block to rotate, which can achieve a stable splicing effect. The second infrared sensor can control the equipment to switch between welding mode and splicing mode.

Detailed Implementation

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: Please refer to the appendix. Figure 1 and attached Figure 4 This invention provides an electric wheelchair frame welding assembly positioning platform, including a work platform 1. Multiple sets of positioning holes 2 are symmetrically opened on the upper inner wall of the work platform 1. Material boxes 4 are fixed to both outer walls of the work platform 1. An electric slide table 5 is detachably installed on the upper inner wall of the work platform 1. A processing table 6 is detachably installed on the middle side of the electric slide table 5. A robotic arm 8 is detachably installed on the slider portion of the electric slide table 5. A support frame 7 is fixed to the outer wall of the work platform 1. A cross slide table 9 is fixed to the upper outer wall of the support frame 7. A switching component 10 is provided on the slider portion of the cross slide table 9.

[0025] Specifically, when using this platform, the various parts of the electric wheelchair can be placed on the upper side of the positioning holes 2 on the left and right sides of the work platform 1. At this time, the electric slide table 5 is started, and the slider inside the electric slide table 5 is controlled to slide to the appropriate position. Then, the robotic arm 8 inside the slider picks up the workpiece and places it on the processing table 6 for docking. At this time, the cross slide table 9 installed on the outer wall of the support frame 7 will be adjusted. At this time, the slider part of the cross slide table 9 will control the switching component 10 to weld or screw the workpiece on the processing table 6. After the electric slide table 5 controls the robotic arm 8 to dock with each workpiece, the switching component 10 performs welding. After welding is completed, the robotic arm 8 will pick up the welded workpiece and place it on the unloading box 4. At this time, the whole workpiece will be unloaded through the unloading box 4. At the same time, after all the workpieces on the work platform 1 are welded, the operator can place the whole workpieces on both sides of the unloading box 4 back onto the work platform 1. At this time, the robotic arm 8 clamps the whole workpiece and the switching component 10 performs screw splicing, which can facilitate the welding and splicing of workpieces. Furthermore, the cross slide 9, the electric slide 5, and the robotic arm 8 all use existing technology, which will not be described in detail here. The first section of the robotic arm 8, which is mounted on the inner wall of the electric slide 5, is a rotating connection, and the second section of the robotic arm 8, which is away from the inner wall of the electric slide 5, is a swing connection. A gripper is installed at the top of the second section of the robotic arm 8.

[0026] Please see the appendix Figure 1 - Appendix Figure 3 The lower surface of the work platform 1 is provided with a control component 3, which includes a mounting box 31. The upper surface of the mounting box 31 is detachably mounted on the lower surface of the work platform 1. The inner wall of the mounting box 31 is fixedly connected to a first electric push rod 32. The output end of the first electric push rod 32 is fixedly provided with a control console 33. The outer wall of the control console 33 is slidably connected to the inner wall of the work platform 1. The outer wall of the control console 33 is fixedly connected to multiple sets of limit blocks 34. The outer walls of the limit blocks 34 are slidably connected to the inner wall of the work platform 1. The upper surface of the control console 33 is provided with multiple sets of bases 35. The outer wall of the base 35 is slidably connected to the inner wall of the positioning hole 2 opened in the work platform 1. The inner wall of the base 35 is slidably connected to a positioning post 36. The lower surface of the positioning post 36 and the inner wall of the base 35 are fixedly connected to a first elastic element 38. The inner wall of the positioning post 36 is detachably mounted with a protective screen 37 and a first infrared sensor 39.

[0027] Specifically, by placing a mounting box 31 on the lower surface of the work platform 1, the mounting box 31 can prevent the control console 33 from falling off. Before the workpiece is placed on the left and right sides of the work platform 1, the first electric push rod 32 is activated to push the control console 33 to slide on the inner wall of the work platform 1. At the same time, the control console 33 will drive the limit block 34 to slide synchronously, so the limit block 34 can prevent the control console 33 from deviating during the sliding process. When the upper surface of the console 33 is in contact with the inner wall of the work platform 1, the outer walls of the multiple sets of bases 35 will be in contact with the multiple sets of positioning holes 2 on the inner wall of the work platform 1. At this time, the workpiece is placed on the left and right sides of the work platform 1, so that the workpiece will press down the positioning column 36 and slide on the inner wall of the base 35. At the same time, the positioning column 36 compresses the first elastic element 38, while the other positioning columns 36 that are not pressed down will position the workpiece. At this time, the positioning columns 36 that are not pressed down will detect the length and width of the tool through the first infrared sensor 39, and the protective screen 37 installed on the inner wall of the positioning column 36 will protect the first infrared sensor 39, which can prevent the workpiece from damaging the first infrared sensor 39. When the first infrared sensor 39 detects various values ​​of the workpiece, it sends them to the terminal via the control console 33. At this time, the terminal controls the electric slide table 5 and the robotic arm 8 to pick up the corresponding workpiece and place it on the processing table 6 for welding and splicing. When resetting, the first electric push rod 32 pulls the control console 33 to slide, and at this time the first elastic element 38 pushes the pressed positioning column 36 to reset.

[0028] Example 2: Please refer to the appendix. Figure 5 - Appendix Figure 9The switching component 10 includes a servo motor 1001. The outer wall of the servo motor 1001 is fixedly connected to the inner wall of the slider of the cross slide table 9. A hollow column 1002 is fixedly provided at the output end of the servo motor 1001. A second electric push rod 1003 is fixedly connected to the inner wall of the hollow column 1002. A guide column 1004 is fixedly provided at the output end of the second electric push rod 1003. A locking block 1006 is slidably connected to the inner wall of the guide column 1004. The outer wall of the locking block 1006 is connected to... A second elastic element 1005 is fixedly connected between the inner walls of the guide post 1004. A first adjusting ring 1007, a first magnetic ring 1008, and a second magnetic ring 1015 are respectively attached to the outer walls of the guide post 1004. The outer walls of the first adjusting ring 1007 and the second adjusting ring 1009 are slidably connected to the inner walls of the hollow post 1002. The outer walls of the locking blocks 1006 are all locked to the inner walls of the first adjusting ring 1007 and the second adjusting ring 1009. Both the first adjusting ring 1007 and the second adjusting ring 1009 are made of iron. The outer walls of the first magnetic ring 1008 and the second magnetic ring 1015 are fixedly connected to the inner wall of the hollow column 1002. The upper and lower outer walls of the first magnetic ring 1008 are attached to the outer walls of the second adjusting ring 1009 and the first adjusting ring 1007. One outer wall of the second magnetic ring 1015 is attached to the outer wall of the second adjusting ring 1009, and the other outer wall of the second magnetic ring 1015 is attached to an iron material. The third adjusting ring 1016 is manufactured, and the outer wall of the third adjusting ring 1016 is provided with a disassembly and assembly assembly 1017. The outer wall of the third adjusting ring 1016 is slidably connected to the inner wall of the hollow column 1002. The inner wall of the hollow column 1002 is fixedly connected to a limiting post 1018. The outer wall of the limiting post 1018 is slidably connected to the inner walls of the first adjusting ring 1007, the first magnetic ring 1008, the second adjusting ring 1009, the second magnetic ring 1015 and the third adjusting ring 1016 respectively.

[0029] Specifically, the servo motor 1001 is activated to drive the hollow column 1002 to rotate, which can adjust the welding and clamping angles to adapt to different workpieces for docking. When the slider of the cross slide table 9 moves the switching component 10 above the first electric push rod 32 for welding, the second electric push rod 1003 is activated to push the guide column 1004 to slide. At this time, after the guide column 1004 slides to the appropriate position, the second elastic element 1005 will push the locking block 1006 to lock the first adjusting ring 1007. At this time, the push and pull of the second electric push rod 1003 will pass through the guide column 1004. The first adjusting ring 1007 slides synchronously on the inner wall of the hollow column 1002. At this time, the first adjusting ring 1007 will drive the welding assembly 1014 to slide synchronously, thereby achieving the effect of adjusting the welding position of the welding assembly 1014. At this time, the first adjusting ring 1007 will slide between the inner wall of the hollow column 1002 and the outer wall of the first magnetic ring 1008. When the guide column 1004 disengages from the first adjusting ring 1007, the first magnetic ring 1008 fixed on the inner wall of the hollow column 1002 will magnetically attract the first adjusting ring 1007, which can facilitate the reset of the first adjusting ring 1007. When workpieces need to be assembled or clamped, the second electric push rod 1003 pushes the guide post 1004 to disengage from the first adjusting ring 1007 and the first magnetic ring 1008, causing the guide post 1004 to contact the second adjusting ring 1009. Since the outer wall of the second adjusting ring 1009 is magnetically attracted to the outer wall of the first magnetic ring 1008, the guide post 1004 drives the locking block 1006 to lock the second adjusting ring 1009, allowing the second adjusting ring 1009 to slide between the outer wall of the first magnetic ring 1008 and the inner wall of the second magnetic ring 1015. When the guide post 1004 drives the first... When the second adjusting ring 1009 contacts the second magnetic ring 1015, the second adjusting ring 1009 will drive other contact clamping workpieces. When the guide post 1004 disengages from the second adjusting ring 1009 and contacts the disassembly assembly 1017, the second adjusting ring 1009 will be magnetically attracted to the outer wall of the second magnetic ring 1015. At the same time, the guide post 1004 will drive the disassembly assembly 1017 and the third adjusting ring 1016 to disengage from the magnetic attraction of the second magnetic ring 1015, thereby allowing the disassembly assembly 1017 and the third adjusting ring 1016 to slide between the second magnetic ring 1015 and the inner wall of the hollow post 1002. The structure of the inner wall of the hollow column 1002, arranged from bottom to top, consists of a guide post 1004, a first adjusting ring 1007, a first magnetic ring 1008, a second adjusting ring 1009, a second magnetic ring 1015, a third adjusting ring 1016, and a disassembly / assembly assembly 1017. Two sets of limiting posts 1018 are fixed to the inner wall of the hollow column 1002, and the first adjusting ring 1007, the second adjusting ring 1009, the third adjusting ring 1016, and the disassembly / assembly assembly 1017 all slide on... The outer wall of the limiting post 1018 allows the guide post 1004 to slide while driving the movement of each component. The outer wall of the limiting post 1018 has a second magnetic ring 1015 and a first magnetic ring 1008. The second magnetic ring 1015 and the first magnetic ring 1008 are fixed to the inner wall of the hollow post 1002, which can prevent the first adjusting ring 1007, the second adjusting ring 1009, the third adjusting ring 1016 and the disassembly assembly 1017 from shifting.

[0030] Please see the appendix Figure 7 and attached Figure 11 The inner wall of the second adjusting ring 1009 is rotatably connected to two sets of right-angle rods 1010. The outer walls of the two sets of right-angle rods 1010 are slidably connected to the second clamping plate 1013 and the first clamping plate 1012, respectively. The inner walls of the second clamping plate 1013 and the first clamping plate 1012 are respectively provided with guide grooves 1011. The outer walls of the right-angle rods 1010 are slidably connected to the inner walls of the guide grooves 1011. The inner wall of the second clamping plate 1013 away from the right-angle rods 1010 is provided with screw grooves. The outer wall of the second clamping plate 1013 away from the right-angle rods 1010 is attached to the inner wall of the first clamping plate 1012. The inner walls of the second clamping plate 1013 and the first clamping plate 1012 are rotatably connected to the outer wall of the hollow column 1002.

[0031] Specifically, when the screw is placed into the disassembly / reassembly assembly 1017, the guide post 1004 will enter the docking mode and dock with the second adjusting ring 1009. At this time, the reciprocating sliding of the second adjusting ring 1009 will drive the right-angle rod 1010 to slide synchronously. The right-angle rod 1010 will slide in the guide groove 1011 of the second clamping plate 1013 and the first clamping plate 1012. Since the second clamping plate 1013 and the first clamping plate 1012 both rotate on the outer wall of the hollow post 1002, the second adjusting ring 1009 drives the second clamping plate 1013 and the first clamping plate 1012 to rotate through the right-angle rod 1010. After the second clamping plate 1013 has finished rotating... It will dock with the first clamping plate 1012, and the hexagonal groove of the second clamping plate 1013 will correspond to the center of the hollow column 1002. The hexagonal groove of the second clamping plate 1013 has a magnetic attraction design, so that the nut will be attracted when placed in the hexagonal groove. At this time, the guide column 1004 will disengage from the second adjusting ring 1009 and contact the disassembly and assembly component 1017. The second adjusting ring 1009 will be attracted by the second magnetic ring 1015 to maintain the clamping state. At this time, the guide column 1004 will drive the disassembly and assembly component 1017 to slide and rotate, so that the screw in the disassembly and assembly component 1017 docks with the nut in the second clamping plate 1013, which can achieve the effect of easy splicing. When there are screws inside the assembly 1017, the guide post 1004 will contact the second adjusting ring 1009 to enter the clamping and splicing mode. When there are no screws inside the assembly 1017, the guide post 1004 will contact the first adjusting ring 1007 to enter the welding mode.

[0032] Please see the appendix Figure 6 and attached Figure 7 The outer wall of the first adjusting ring 1007 is provided with a welding assembly 1014. The welding assembly 1014 includes a connecting rod 10141. The outer wall of the connecting rod 10141 is fixedly connected to the outer wall of the first adjusting ring 1007. The outer wall of the connecting rod 10141 is slidably connected to the inner wall of the hollow column 1002. An arc plate 10142 is fixedly connected to the outer wall of the connecting rod 10141. A welding head 10143 is fixedly connected to the outer wall of the arc plate 10142. A laser sensor 10144 is provided on the outer wall of the welding head 10143.

[0033] Specifically, when the guide post 1004 is connected to the first adjusting ring 1007, the reciprocating sliding of the guide post 1004 will drive the connecting rod 10141 to slide synchronously through the first adjusting ring 1007. The connecting rod 10141 slides on the inner wall of the hollow post 1002, which can prevent the connecting rod 10141 from deviating. The connecting rod 10141 drives the arc plate 10142 to slide synchronously, so that the arc plate 10142 drives the welding head 10143 to slide synchronously, which can keep the welding head 10143 in contact with the workpiece, achieving a stable welding effect. At the same time, the laser sensor 10144 installed on the outer wall of the welding head 10143 will detect the welding position of the workpiece in real time, and at the same time, it is convenient for the cross slide table 9 to control the switching component 10 to accurately find the welding and screw docking positions.

A second infrared sensor 10175 is detachably installed at the through hole of the cross block 10174. The outer walls of the sliding column 10171 and the concave ring 10173 are slidably connected to the inner wall of the hollow column 1002. The inner walls of the sliding column 10171 and the third adjusting ring 1016 are both attached to the outer wall of the guide column 1004.

[0035] Specifically, before switching between welding mode and docking mode, the second infrared sensor 10175 monitors in real time whether screws are attached to the assembly / disassembly component 1017. The cross-shaped block 10174 uses a magnetic design to facilitate screw attachment. When splicing is required, the guide post 1004 docks with the third adjusting ring 1016 and the sliding post 10171. The third adjusting ring 1016 and the sliding post 10171 are fixedly connected, allowing them to slide synchronously. When the slide column 10171 slides to the appropriate position, the position is monitored by the laser sensor 10144. At this time, the drive motor 10172 is started to drive the concave ring 10173 to rotate, and the concave ring 10173 will drive the cross block 10174 to rotate synchronously, which can facilitate the tightening of screws. When the third adjusting ring 1016 and the slide column 10171 are reset, the third adjusting ring 1016 will be attracted to the second magnetic ring 1015, which can prevent the disassembly and assembly component 1017 from falling off.

[0036] The workflow involves placing the various components of the electric wheelchair on the left and right sides of the work platform 1. The first electric push rod 32 is activated to push the control console 33 to fit against the inner wall of the work platform 1. At this time, multiple sets of bases 35 fit against multiple sets of positioning holes 2 on the inner wall of the work platform 1. The workpiece presses down on the corresponding positioning post 36, causing the positioning post 36 to compress the first elastic element 38. The positioning post 36 that is not pressed down positions the workpiece. At the same time, the positioning post 36 that is not pressed down detects the length and width of the workpiece through the first infrared sensor 39 installed on the inner wall. The detection data is sent to the terminal through the control console 33. After receiving the detection data, the terminal starts the electric slide table 5 to allow the robotic arm 8 to grab the workpiece on the work platform 1 and dock it on the processing table 6. At this time, the slider part of the cross slide table 9 drives the switching component 10 to move above the processing table 6. Then, the servo motor 1001 is started to drive the hollow column 1002 to rotate and adjust the welding angle. Then, the second electric push rod 1003 pushes the guide column 1004 to dock with the first adjusting ring 1007. At this time, the connecting rod 10141 slides on the inner wall of the hollow column 1002. At the same time, the arc plate 10142 and the welding head 10143 slide synchronously, so that the welding head 10143 is always in contact with the workpiece, which can achieve stable welding. The laser sensor 10144 can detect the welding position in real time. The second infrared sensor 10175 monitors in real time whether screws are attached to the disassembly assembly 1017. Once a screw is confirmed, the system switches to the splicing mode. At this time, the second electric push rod 1003 pushes the guide post 1004 to disengage from the first adjusting ring 1007 and the first magnetic ring 1008, and contacts the second magnetic ring 1015, causing the first clamping plate 1012 and the second clamping plate 1013 to rotate and engage, thereby clamping the workpiece. After the guide post 1004 engages with the third adjusting ring 1016, the drive motor 10172 is started to drive the concave ring 10173 and the cross block 10174 to rotate, thereby turning the screws in the disassembly assembly 1017 and engaging with the nuts in the second clamping plate 1013 to complete the splicing.
