Description

Technical Field

[0001] This invention belongs to the field of assembly equipment, and specifically relates to an automatic assembly equipment for electric bicycles. Background Technology

[0002] In electric bicycle production, assembly is generally divided into assembly line and single-station assembly. Assembly lines excel at producing large quantities of standard products efficiently, but when faced with small-batch orders, mixed production of multiple models, or highly customized orders, the cost and downtime associated with frequent tooling changes make them uneconomical. Single-station assembly, on the other hand, allows for rapid response to changes and flexible adjustments to assembly plans. During new product development and trial production, or when reworking defective vehicles, single-station assembly facilitates process verification or fine-tuning. Therefore, single-station assembly is a supplementary solution for non-standard, trial, or special needs, its core being the sacrifice of economies of scale for high flexibility in production organization.

[0003] For example, Chinese patent application CN201720029339.3 discloses an integrated bicycle assembly machine. This machine fixes the bicycle frame and controls the lifting mechanism based on the assembly of parts and the operator's own conditions. The frame angle is adjusted according to the assembly position and ease of adjustment of the parts. The machine's multi-faceted adjustability satisfies the convenience and operability of manual assembly. While highly flexible, this device lacks sufficient stability for the entire bicycle frame, easily causing wobbling and shifting during assembly, affecting assembly quality. Another example is Chinese patent application CN202610738617.6, which discloses a multi-directional adjustment device for electric bicycle assembly. This device suspends the frame using a fixing plate and abutment blocks. Hang the device, then rotate screw two to control the engagement of the trapezoidal locking block and the wedge-shaped locking groove, adjust the extension and retraction of the sliding plate, and cooperate with the rotation of the abutment ring. Through the engagement of the internal thread three and the external thread, the arc-shaped locking block is pushed into the telescopic groove two, causing the arc-shaped locking block to disengage from the moving cavity, driving the connecting plate one and the fixing plate two to move. In conjunction with the telescopic movement of the wedge-shaped locking groove, the upper abutment block conforms to the shape of the frame to be assembled, driving the connecting plate and the fixing block to move up and down, realizing the rapid support and abutment of the frame. While quickly matching various types of electric bicycles, it clamps and fixes the frame to prevent the frame from shaking during assembly. The device has good stability and the vehicle body is stable during assembly, but its flexibility is slightly insufficient. It is inconvenient to adjust the angle of the frame during assembly, which affects the assembly efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an automated assembly equipment for electric bicycles. This equipment can not only securely clamp various frames but also conveniently adjust the assembly angle and position of the frames, effectively improving the overall assembly efficiency of electric bicycles.

[0005] To achieve the above objectives, the specific technical solution of the present invention is as follows: An automated assembly device for electric bicycles includes a mounting base, a fixed support mechanism, an adjusting bracket mechanism, a main support frame, and an auxiliary support device. The mounting base has a rotating platform, on which a workbench is fixedly mounted. A horizontally positioned, right-protruding fixed cylinder is fixedly connected to the upper end of the workbench. A driving device is located at the left end of the fixed cylinder. The fixed support mechanism includes a fixed suspension fixedly mounted on the right side of the workbench and directly below the fixed cylinder. The fixed suspension is parallel to the fixed cylinder. A first rotating disk and a second rotating disk are axially positioned and rotatably connected at both ends of the fixed suspension. The first and second rotating disks are linked by a fixed rod. The auxiliary support device includes an auxiliary support tube hinged to the first rotating disk. A sliding square tube is slidably connected to the auxiliary support tube. An auxiliary support platform is rotatably connected to the outer end of the sliding square tube. A second telescopic gas spring device is fixedly mounted on the auxiliary support tube. The telescopic rod of the second telescopic gas spring device is fixedly connected to the sliding square tube. A support tube perpendicular to the fixed suspension is fixedly connected to the second rotating disk. The auxiliary support tube can only swing within the plane containing the support tube and the fixed rod.

[0006] As a further feature of the above scheme, the adjusting support mechanism includes a driving square rod rotatably connected to the fixed cylinder via a rotating flange. The left end of the driving square rod is connected to the driving device, and the right end of the driving square rod is fixedly connected to a connecting platform. An adjusting support tube parallel to the support tube is fixedly connected to the connecting platform. The connecting platform and the second rotating disk are linked together through a fixed plate. A first telescopic pneumatic rod device parallel to the adjusting support tube is installed on the fixed plate.

[0007] As a further provision of the above scheme, the main support frame device includes a sliding bracket, which includes an upper sliding tube and a lower sliding tube arranged parallel to each other. The upper sliding tube and the lower sliding tube are linked together by a reinforcing tube, which is fixedly connected to the telescopic rod of the first telescopic air rod device. An upper clamping device is detachably installed at the outer end of the upper sliding tube, and a lower clamping device corresponding to the upper clamping device is fixedly installed at the outer end of the lower sliding tube.

[0008] As a further provision of the above scheme, the driving device includes two drive motors fixedly mounted on the workbench, a transmission gear fixedly mounted on the output shaft of the drive motor, and a drive gear plate and a locking gear plate fixedly mounted on the left end of the drive rod, the drive gear plate and the locking gear plate being meshed with the transmission gear.

[0009] As a further feature of the above solution, an upper mounting bracket is provided at the outer end of the upper sliding tube. The upper mounting bracket has two vertically penetrating upper mounting holes, and mounting shafts are inserted into the upper mounting holes. The upper clamping device includes a semi-circular semi-disc. An electric telescopic device is provided at the center of the upper surface of the semi-disc. A limiting block capable of vertical movement is installed on the telescopic end of the electric telescopic device. Symmetrically arranged vertically penetrating arc grooves are provided on the semi-disc. A fixed ear plate is provided at one end of the axial section of the semi-disc. A rotating hole corresponding to the upper mounting hole is provided on the fixed ear plate. When two mounting shafts are simultaneously inserted into the upper mounting hole and the rotating hole, the upper clamping device is fixedly installed on the upper sliding tube. When one mounting shaft is inserted into one upper mounting hole and one rotating hole, the upper clamping device is rotatably installed on the upper sliding tube.

[0010] As a further provision of the above solution, the lower clamping device includes a lower support platform fixedly installed at the outer end of the sliding tube, and a support bushing with an upward opening and coaxial with the semi-circular disk is installed on the lower support platform.

[0011] As a further provision of the above scheme, the auxiliary support platform is rotatably mounted on the sliding square tube via a rotating platform. The auxiliary support platform is provided with an auxiliary positioning shaft device, which includes an auxiliary positioning shaft that is vertically slidably inserted into the auxiliary support platform. A positioning shaft sleeve is sleeved on the auxiliary positioning shaft, and a locking nut is screwed onto the upper end of the auxiliary positioning shaft.

[0012] The beneficial effects of this invention are: This device uses an upper clamping device and a lower clamping device to clamp and fix the vertical tube and positioning groove on the front fork of the frame body. The second telescopic gas spring device drives the sliding square tube to slide on the auxiliary support tube through the telescopic rod, adjusting the position of the auxiliary support platform. The angle of the auxiliary support platform is adjusted by the rotating table, so that the auxiliary positioning shaft is aligned with the central axis of the semi-circular disk. The auxiliary positioning shaft is pushed upward and inserted into the middle tube of the frame body. The locking nut is screwed onto the auxiliary positioning shaft, fixing the middle tube to the auxiliary support device. The auxiliary support device, together with the upper clamping device and the lower clamping device, provides three-point fixation for the frame body, preventing the frame body from shaking during assembly, ensuring the stability of the frame body during assembly, and achieving stable clamping of frame bodies of various specifications, effectively improving the assembly quality.

[0013] After the frame body is securely clamped, the first and second telescopic air rod devices work together to extend and retract synchronously, flexibly adjusting the angle of the frame body during assembly; the first and second telescopic air rod devices also work together to extend or retract synchronously, flexibly adjusting the position of the frame body during assembly; the drive motor drives the drive gear to rotate through the transmission gear, which in turn drives the drive square rod to rotate, causing the adjusting bracket tube to swing, which in turn causes the support tube and auxiliary bracket tube to swing synchronously, causing the entire frame body to rotate in a revolution motion, adjusting the height of the frame body while further improving the flexibility of angle adjustment during frame body assembly. This device can easily and efficiently adjust the assembly angle and position of the frame, effectively improving the overall assembly efficiency of the electric bicycle. Attached Figure Description

[0021] The main support frame device 7 includes a sliding bracket 701, which includes an upper sliding tube 7011 and a lower sliding tube 7012 arranged parallel to each other. The upper sliding tube 7011 and the lower sliding tube 7012 are linked together by a reinforcing tube 7013. The reinforcing tube 7013 is fixedly connected to the telescopic rod 1101 of the first telescopic air rod device 10. An upper clamping device 702 is detachably installed at the outer end of the upper sliding tube 7011, and a lower clamping device 703 corresponding to the upper clamping device 702 is fixedly installed at the outer end of the lower sliding tube 7012.

[0022] like Figure 4As shown, the drive device 301 includes two drive motors 302 fixedly mounted on the workbench 3. A transmission gear 303 is fixedly mounted on the output shaft of the drive motor 302. A drive gear 304 and a locking gear 305 are fixedly mounted on the left end of the drive rod 601. The drive gear 304 and the locking gear 305 are meshed with the transmission gear 303.

[0023] As shown in the figure Figure 4 , Figure 5 As shown, the upper sliding tube 7011 has an upper mounting bracket 7014 at its outer end. The upper mounting bracket 7014 has two vertically penetrating upper mounting holes 7015, and a mounting shaft 7016 is inserted into the upper mounting holes 7015. The upper clamping device 702 includes a semi-circular semi-disc 7021. An electric telescopic device 7023 is provided at the center of the upper end face of the semi-disc 7021. A vertically movable limiting block 7024 is installed on the telescopic end of the electric telescopic device 7023. Symmetrically arranged vertically penetrating arcs are provided on the semi-disc 7021. The groove 7022 and the semi-circular disk 7021 have a fixed ear plate 7025 at one end of their axial section. The fixed ear plate 7025 has a rotating hole 7026 that corresponds to the upper mounting hole 7015. When two mounting shafts 7016 are simultaneously inserted into the upper mounting hole 7015 and the rotating hole 7026, the upper clamping device 702 is fixedly installed on the upper slide tube 7011. When one mounting shaft 7016 is inserted into one upper mounting hole 7015 and the rotating hole 7026, the upper clamping device 702 is rotatably installed on the upper slide tube 7011.

[0024] like Figure 5 As shown, the lower clamping device 703 includes a lower support platform 7031 fixedly installed at the outer end of the sliding tube 7012, and a support bushing 7032 with an upward opening and co-axial with the semi-circular disk 7021 is installed on the lower support platform 7031.

[0025] like Figure 7 , Figure 8 As shown, the auxiliary support platform 803 is rotatably mounted on the sliding square tube 802 via the rotating platform 8031. The auxiliary support platform 803 is provided with an auxiliary positioning shaft device 804. The positioning shaft device 804 includes an auxiliary positioning shaft 8042 that is vertically slidably inserted into the auxiliary support platform 803. A positioning shaft sleeve 8042 is sleeved on the auxiliary positioning shaft 8041. A locking nut 8043 is screwed onto the upper end of the auxiliary positioning shaft 8041.

[0026] The working process of this equipment is as follows: First, remove one mounting shaft 7016, swing the upper clamping device 702 outward to offset the upper clamping device 702 from the lower clamping device 703, invert the frame body 9, insert the vertical tube into the support bushing 7032, rotate the upper clamping device 702 inward, and re-insert the removed mounting shaft 7016 into the upper mounting hole 7015 and the rotating hole 7026. The side arm of the front fork 902 is engaged in the arc groove 7022. Activate the electric telescopic device 7023 to drive the limit block 7024 to abut against the positioning groove 903, and perform preliminary clamping and fixing of the frame body 9.

[0027] The second telescopic pneumatic rod device 11 drives the sliding square tube 802 to slide on the auxiliary support tube 801 via the telescopic rod 1101, adjusting the position of the auxiliary support platform 803. The angle of the auxiliary support platform 803 is adjusted by the rotating table 8031, so that the auxiliary positioning shaft 8041 is on the same central axis as the semi-circular disk 7021. The auxiliary positioning shaft 8041 is pushed upward, and the auxiliary positioning shaft 8041 is inserted into the middle tube 901 of the frame body 9. The locking nut 8043 is screwed onto the auxiliary positioning shaft 8041, fixing the middle tube 901 onto the auxiliary support device 8. The auxiliary support device 8, together with the upper clamping device 702 and the lower clamping device 703, performs three-point fixation on the frame body 9 to prevent the frame body 9 from shaking during assembly.

[0028] After the frame body 9 is securely clamped, the first telescopic air rod device 10 and the second telescopic air rod device 11 work together to extend and retract synchronously, flexibly adjusting the angle of the frame body 9 during assembly. The first telescopic air rod device 10 and the second telescopic air rod device 11 work together to extend or retract synchronously, flexibly adjusting the position of the frame body 9 during assembly. The rotary table device 2 drives the workbench to rotate, adjusting the position of the frame body 9. The drive motor 302 drives the drive gear 304 to rotate through the transmission gear 303, which in turn drives the drive square rod 601 to rotate, causing the adjusting bracket tube 6021 to swing. Through the fixing plate 603 and the fixing rod 5021, the support tube 504 and the auxiliary bracket tube 801 swing synchronously, causing the frame body 9 to rotate as a whole. While adjusting the height of the frame body 9, the angle adjustment flexibility during frame body assembly is further improved. The drive motor 302 locks the drive square rod 601 through the locking gear 305 to ensure stability.

[0029] When assembling the front wheel of the electric bicycle, pull out another mounting shaft 7016 and swing the upper clamping device 702 outward so that the upper clamping device 702 is completely misaligned with the lower clamping device 703. The upper clamping device 702 is away from the front fork 901 and does not affect the assembly of the front wheel and the front fork.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
