Description

Technical Field

[0001] This utility model belongs to the field of scooter assembly technology, and in particular relates to a safety scooter assembly device. Background Technology

[0002] A scooter is a device whose main structure includes a frame and wheels mounted at the bottom of the frame. Based on their working principle, they can be divided into electric and non-electric scooters. Electric scooters are equipped with a battery module to enable automatic rolling during use.

[0003] The production and manufacturing process of electric scooters requires the assembly of numerous components, including the power supply, handlebars, wheels, wiring, and brake levers. The current assembly method involves suspending the frame on a U-shaped work stand and then assembling each component sequentially according to the assembly process.

[0004] However, the drawback of the above assembly method is that the operator needs to be extremely familiar with each assembly step, such as power supply assembly, handle assembly, wiring assembly, brake lever assembly, etc. Therefore, it requires a high level of skill and experience from the operator.

[0005] Therefore, in actual work, a separate assembly method is often adopted. This involves several operators working together to assemble the parts according to a specific assembly sequence. Each operator is only responsible for a few steps in the assembly. This method not only has high assembly efficiency but also requires less skill and experience from the operators and has a relatively low error rate. Therefore, this method is frequently used in actual work.

[0006] However, the drawback of this method is that after an operator assembles the product, it is difficult to transfer the unfinished semi-finished product to the operator in the next assembly process. In other words, how to transfer the semi-finished product during the assembly process becomes a technical problem. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a safe scooter assembly device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A safety scooter assembly device includes a track, on which several scooter assembly mechanisms are rolled, and each assembly mechanism includes a vehicle structure that rolls autonomously on the track.

[0010] The traveling vehicle structure is equipped with an assembly structure, which includes a rotatable turntable structure and a support structure for a material unloading trolley frame mounted on the turntable structure.

[0011] The support structure includes several height-adjustable brackets, and the scooter frame is positioned between the adjustable brackets.

[0012] The adjusting bracket has a fixed internal support structure that supports the scooter frame from the bottom.

[0013] Preferably, the vehicle structure includes a turntable mounting base at the bottom of the turntable structure;

[0014] The bottom of the turntable mounting base is fixedly installed with a trolley frame structure;

[0015] The trolley frame structure includes a frame, and a pair of traveling rollers that roll on a track are respectively installed on both sides of the frame.

[0016] Preferably, the walking roller structure includes a roller bracket, and rotating rollers are respectively installed on both sides of the roller bracket;

[0017] The roller bracket is rotatably connected to an active roller that rolls at the top of the track, and the roller bracket is equipped with a motor that drives the active roller to rotate.

[0018] Preferably, a long roller groove for limiting the rotation of the roller is formed on the side wall of the track;

[0019] The top of the track has a long roller groove that mates with the drive roller.

[0020] Preferably, the turntable structure includes a fixed platform that is fixedly installed at the top of the turntable mounting base;

[0021] It also includes a turntable that is rotatably connected to a fixed platform;

[0022] A pair of spaced-apart adjustment brackets are installed on the top of the turntable.

[0023] Preferably, a central rotating shaft is fixedly installed at the center of the turntable, and a bearing rotatably connected to the central rotating shaft is fixedly installed at the center of the top of the fixed platform;

[0024] Several circumferentially distributed support rollers are installed on the outer wall of the turntable, and the support rollers roll on the top edge of the fixed platform.

[0025] The top edge of the fixed platform is provided with an annular groove that cooperates with the rotating support roller, and the rotating support roller is limited to rolling within the annular groove.

[0026] Preferably, the adjusting bracket includes a U-shaped part, with horizontal parts integrally formed on both sides of the U-shaped part, and a pair of adjusting screws that are slidably connected to the horizontal parts are fixedly connected to the top two sides of the turntable;

[0027] The upper end of the fixed adjusting screw is threaded with a pair of nuts that are locked on both sides of the horizontal part.

[0028] Preferably, the bracket structure includes a pair of height-adjustable limiting columns;

[0029] The lower ends of the limiting columns are fixedly connected to a support rod bracket that supports the bottom of the scooter frame.

[0030] Preferably, each of the limiting columns is slidably connected to an adjustment screw, and the bottom of the adjustment screw is fixedly installed at the top position of the U-shaped part;

[0031] The upper and lower ends of the high-adjustment screw are respectively threaded with a pair of high-adjustment nuts that are locked and positioned at the top and bottom of the limiting column.

[0032] This utility model has the following beneficial effects:

[0033] 1. During the operation, the four motors and active rollers on the trolley frame structure synchronously drive the trolley frame structure to move on the track, thus transferring the loaded trolley frame between different assembly personnel (assembly station).

[0034] The assembly line assembly method described above breaks down the complex assembly steps according to the assembly process, with each operator responsible for several steps. This not only greatly reduces the error rate of assembly operations, but also lowers the skill and experience requirements for assembly personnel, thereby reducing production costs and significantly improving assembly efficiency.

[0035] 2. The adjustable bracket and support structure allows for dual height adjustment from the outside, inside, and both overall and partial levels, facilitating the assembly of the scooter frame. For example, raising the frame for power supply assembly and lowering the frame for control lever assembly increases assembly efficiency. The flexible height adjustment enhances assembly efficiency. The bracket structure supports the scooter frame while simultaneously positioning it in a non-locking manner, ensuring high stability and facilitating frame rotation during operation for easy installation of components such as the bottom wheels.

[0036] 3. By using the rotating rollers for support, the assembly process can be facilitated when the scooter frame needs to be rotated to face the operator. Attached Figure Description

[0048] Example 1

[0049] like Figure 1-6 As shown, a safety scooter assembly device includes a track 1 (the track 1 includes track sections 11 spaced apart on the front and rear sides, and track supports 12 are fixedly installed between the bottoms of the track sections 11). Several scooter assembly mechanisms 2 (only two are shown in the figure, but in actual operation, multiple are often designed according to the complexity of the assembly process) roll on the track 1. The assembly mechanism 2 includes a walking vehicle structure that rolls autonomously on the track 1.

[0050] The mobile trolley structure allows an operator to assemble the scooter in several steps, and then the entire device moves to the next assembler's position to continue assembling. This process is repeated, allowing multiple assemblers on the production line to complete the assembly of the entire scooter in stages.

[0051] At this point, the idle trolley structure on track 1 will move back to the position of the first assembly step. This process is repeated until all the trolley structures on track 1 have been used. The assembled trolley structures are then concentrated at the right end of track 1, and all the trolley structures return to the left end (starting section) of track 1.

[0052] Specifically, the vehicle structure includes a turntable mounting base 21 at the bottom of the turntable structure; a trolley frame structure is fixedly mounted on the bottom of the turntable mounting base 21; the bottom of the turntable mounting base 21 and the top of the trolley frame structure are fixedly mounted by a number of support columns 211, which are distributed at the four corners of the trolley frame structure.

[0053] The aforementioned trolley frame structure includes a frame 22 (in the shape of a frame structure), and a pair of traveling roller structures 23 that roll on the track 1 are respectively installed on the front and rear sides of the frame 22. The traveling roller structures 23 are spaced apart on the left and right sides.

[0054] Specifically, the walking roller structure 23 includes a roller bracket (fixedly installed at the corner of the frame), and a rotating roller 232 is installed on the front and rear sides of the roller bracket (the rotating roller 232 is rotatably connected to the roller bracket in the same way as in the existing method, such as through a wheel axle installed on the roller bracket).

[0055] Meanwhile, a drive roller 231 that rolls at the top of track 1 is rotatably connected to the roller bracket, and a motor 233 that drives the drive roller 231 to rotate is mounted on the roller bracket. The motor 233 is fixedly mounted on the roller bracket in the same way as existing motors 233 drive roller rotation, and the output shaft of the motor 233 is fixedly mounted on the drive roller 231.

[0056] To increase the stability of walking, long roller grooves A for limiting the rotation roller 232 are opened on the front and rear side walls of the track 1; a long roller groove A that cooperates with the drive roller 231 is opened on the top of the track 1.

[0057] During operation, the four motors 233 and the active rollers 231 on the trolley frame structure are synchronously driven to move on track 1 in the existing manner. During the movement, the loaded trolley frame is transferred between different assembly personnel (assembly station).

[0058] The assembly line assembly method described above breaks down the complex assembly steps according to the assembly process, with each operator responsible for several steps. This not only greatly reduces the error rate of assembly operations, but also lowers the skill and experience requirements for assembly personnel, thereby reducing production costs and significantly improving assembly efficiency.

[0059] Example 2

[0060] like Figure 1-6 As shown, based on the structure of Embodiment 1, this embodiment further improves the assembly structure to enhance assembly efficiency and ease of operation during the assembly process:

[0061] Specifically, the traveling vehicle structure is equipped with an assembly structure 24, which includes a rotating turntable structure and a support structure for the material unloading trolley frame 3.

[0062] Specifically, the support structure includes a pair of symmetrically arranged, height-adjustable adjustable supports 243, with the scooter frame 3 positioned between the adjustable supports 243. Simultaneously, a bracket structure supporting the scooter frame 3 from the bottom is fixedly connected within each adjustable support 243.

[0063] The purpose of height adjustment is to adjust the height of the scooter frame 3 during the assembly process by adjusting the height of the bracket 243 and the bracket structure described below. For example, increasing the height makes it easier to install the power module at the bottom of the scooter frame 3, while lowering the height makes it easier for the operator to install the control lever on the scooter.

[0064] Specifically, the adjusting bracket 243 includes a U-shaped part, with horizontal parts integrally formed on both sides of the U-shaped part. A pair of fixed adjusting screws 2431 that are slidably connected to the horizontal parts are fixedly connected to the top two sides of the turntable. A pair of nuts 24311 that are locked to the horizontal parts are threaded to the upper end of the fixed adjusting screws 2431.

[0065] The adjustment method is as follows: loosen the nut to achieve overall adjustment. For example, after the height of the scooter frame 3 is greatly increased, it is convenient to install the power supply at the bottom of the scooter frame 3.

[0066] Meanwhile, during the assembly process, in order to further increase the flexibility of height adjustment, the scooter frame 3 can be further adjusted within a small range, such as to facilitate the installation of the handlebars.

[0067] Specifically, the height of the scooter frame 3 is further adjusted through a bracket structure. The specific structure of the bracket structure is as follows:

[0068] The bracket structure includes a pair of height-adjustable limiting columns 25 (the side wall of the scooter frame abuts against the limiting columns 25, and the two pairs of limiting columns 25 on the left and right sides are used to press the front and rear side walls of the scooter frame 3 together at four points to maintain the stability of the frame).

[0069] Meanwhile, a support rod bracket 251, which supports the bottom of the scooter frame 3, is fixedly connected to the lower end of the limiting column 25. An adjustable screw 252 (with a matching sliding cavity) is slidably connected to the limiting column 25, and the bottom of the adjustable screw 252 is fixedly installed at the top of the U-shaped part. Similarly, a pair of adjustable nuts 2521, locking and positioning themselves at the top and bottom of the limiting column 25, are threaded to the upper and lower ends of the adjustable screw 252, respectively.

[0070] During the adjustment process, the operator also loosens the high-adjustment nut 2521 and adjusts the scooter frame 3, which is supported by the limit column 25 and the support rod bracket structure, in a synchronous lifting and lowering manner. Then, the high-adjustment nut is tightened again to lock the position.

[0071] This method, along with the height adjustment bracket 243 mentioned above, allows for height adjustment of the scooter frame 3 from both the inner and outer sides. However, during assembly, since the power supply of the scooter frame 3 is installed at the bottom of the frame, and the operating control lever (including the handle, brake, and other components on the operating control lever) is higher than the top of the scooter frame 3, the height of the scooter frame 3 needs to be adjusted multiple times during assembly to facilitate installation.

[0072] Example 3

[0073] like Figure 1-6 As shown, this embodiment, based on the structure of embodiment 2, aims to increase assembly flexibility during operation and facilitate the adjustment of the scooter frame 3's posture. For example, after one handlebar is installed, rotating the scooter frame 3 facilitates the installation of the other handlebar. Additionally, for installations such as bolts on both sides of the scooter frame 3, it is necessary to rotate the scooter frame 3 so that the mounting parts face the operator, such as for the installation of lights on the control lever.

[0074] Therefore, the present invention also makes the following improvements: the turntable structure includes a fixed platform 242 fixedly installed at the top of the turntable fixed base 21; and also includes a turntable rotatably connected to the fixed platform 242.

[0075] Specifically, according to the existing rotating connection method, a central rotating shaft is fixedly installed at the center of the turntable, and correspondingly, a bearing for rotating the central rotating shaft is fixedly installed at the top center of the fixed platform 242.

[0076] Meanwhile, a number of circumferentially distributed support rollers 241 are installed on the outer side wall of the turntable, and the support rollers 241 roll on the top edge of the fixed platform 242; the top edge of the fixed platform 242 is provided with an annular groove 2421 that cooperates with the support rollers 241, and the support rollers 241 are limited to roll within the annular groove 2421.

[0077] During assembly, when it is necessary to rotate and adjust the position of the scooter frame 3, the operator rotates the turntable. During the rotation, the rotating rollers 241, which are circumferentially distributed on the outer wall of the turntable, roll on the fixed platform 242-annular groove structure. The advantage of this method is:

[0078] When the power supply is installed on the scooter frame 3, the frame is relatively heavy. If the center of gravity of the frame does not coincide with the center of the turntable (i.e., the scooter frame 3 is not placed in a precise position), the rotation and rolling stability is high due to the support of the rotating rollers 241. This means that even if the center of gravity of the scooter frame 3 is unstable, the turntable can still rotate smoothly when the scooter frame 3 is slightly heavy under the load of the turntable, without the turntable shaking or wobbling due to the instability of rotation (unstable rotation on the plane). This would prevent the scooter frame 3, with its unstable center of gravity, from easily tipping over from the end or end.

[0079] The reason why scooter frame 3 is designed to be freely placed is that it does not employ a positioning structure. This is because during operation, adjustments to the scooter's posture are often needed, such as installing wheels. This requires flipping the scooter over, installing the wheels, and then flipping it back over. Therefore, completely locking the scooter would increase the cumbersomeness of operation. Scooter frame 3, with its four 25mm side-bracing posts, already offers high stability. Therefore, to improve ease of operation, positioning and locking mechanisms were omitted.

[0080] Example 4

[0081] like Figure 1-6 As shown, this embodiment, based on the structure of embodiment 3, allows for the installation of sensors (not shown in the figure) on track 1 using existing methods during actual operation. The sensors are specifically positioned at each workstation location (along the length of track 1). When the traveling vehicle structure moves to the sensor location, the sensor detects the vehicle, at which point motor 233 on the traveling vehicle structure stops, and the operator assembles the vehicle. After assembly, the operator pushes the traveling vehicle structure forward, repeating this process until the final assembly step is completed.

[0082] Using sensors to sense the trolley on track 1 and feeding the sensing signal back to the backend, which then controls the motor 233 on the trolley to stop, is a conventional method disclosed in existing technology.

[0083] Alternatively, in actual work, manual control can be used directly. For example, when the trolley reaches its workstation, the operator at the workstation turns off the switch on the trolley. After assembly, the switch is turned back on, and motor 233 drives the trolley to continue moving forward.

[0084] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
