[0002] A welding and assembly unit for children's balance bikes is a specialized piece of equipment designed to improve assembly efficiency and welding quality. This unit utilizes advanced welding technology to ensure a secure connection between different components, thereby enhancing the structural strength and safety of the balance bike. The welding and assembly unit typically includes automated fixtures, a welding machine, and a control system to facilitate high-precision welding operations while minimizing human error. Furthermore, with the increasing market demand for safe riding products for children, the research and application of high-performance welding and assembly units is of great significance for improving the manufacturing process and quality of children's balance bikes.

[0003] However, some existing welding and assembly devices for children's balance bikes have components that are not easy to fine-tune during the assembly process. This can lead to situations where the components are not properly positioned during assembly, requiring re-fixing and reassembly, which wastes time and manpower. Therefore, this problem needs to be solved. Utility Model Content

The technical problem this utility model aims to solve is that the components are not easy to fine-tune during the assembly process, which leads to the need for re-fixing and reassembly if the position is not suitable during assembly, wasting time and human resources.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Each support seat has a moving mechanism at its bottom for moving the support seats. Two first electric push rods are symmetrically fixedly connected to the tops of the two support seats. A common support plate is fixedly connected to the tops of the two first electric push rods. Four first clamping plates are provided on the top of one of the support plates, arranged in pairs. A slot is provided on one side of each pair of first clamping plates, and a roller is rotatably connected inside each slot. Each of the two sets of first clamping plates has a rotating mechanism for rotating the roller on one side. The other support plate has two fixed blocks symmetrically fixedly connected to its top. Each of the two fixed blocks has an adjusting roller rotatably connected to one side. Each of the two adjusting rollers has a storage groove on one side. Each of the two storage grooves has a third electric push rod fixedly connected inside. Each of the two third electric push rods has a second clamping plate fixedly connected to its output end. Each of the two adjusting rollers has a rotating mechanism for rotating the second clamping plate at its end away from the second clamping plate. By setting up the rollers and adjusting rollers, it can be ensured that the parts can be adjusted during the assembly process.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model adopts a technical solution that uses rollers and adjusting rollers to drive the rotation of parts, thus ensuring that the parts can be adjusted during the assembly process. This effectively solves the problem that parts are not easy to fine-tune during assembly, which leads to the need for re-fixing and reassembly if the position is not suitable during assembly, wasting time and manpower. The clamping surface of the first clamping plate has a slot, and a roller is installed inside the slot. The roller is in close contact with the handlebar.

[0020] Preferably, the moving mechanism includes a bidirectional lead screw 104, which is rotatably connected to one side of the base 1. A first motor 106 is fixedly connected to one end of the bidirectional lead screw 104, and the first motor 106 is fixedly connected to one side of the base 1. A support seat 2 is slidably sleeved on the surface of the bidirectional lead screw 104. A lead screw nut 105 is provided inside the support seat 2 near the side of the bidirectional lead screw 104, and the lead screw nut 105 and the bidirectional lead screw 104 are mutually cooperated. A robotic arm 102 is fixedly connected to one side of the base 1, and a welding head 103 is provided at the end of the robotic arm 102 near the side of the base 1. The support seat 2 can be moved by the bidirectional lead screw 104.

[0021] Preferably, the rotating mechanism includes a second motor 308, which is fixedly connected to one side of the first clamping plate 3. The output shaft of the second motor 308 is fixedly connected to a second synchronous pulley 306. A first synchronous pulley 305 is fixedly sleeved on the surface of the roller 304 near the second synchronous pulley 306. The surfaces of the first synchronous pulley 305 and the second synchronous pulley 306 are sleeved with the same first synchronous belt 307.

[0022] Preferably, the rotating mechanism includes a rotating shaft 405, which is fixedly connected to one end of the adjusting roller 401. A third synchronous wheel 406 is fixedly sleeved on the surface of the rotating shaft 405.

The second clamping plate 404 can be rotated by the setting of the third synchronous wheel 406.

[0023] Working principle: In use, the handlebars are placed between multiple first clamping plates 3, and then the second electric push rod 302 is activated, causing the first clamping plates 3 to move closer together, thus clamping and fixing the handlebars. Then, the connecting rod to be assembled is placed between two second clamping plates 404. A third electric push rod 403 is installed on one side of each of the two second clamping plates 404. When the third electric push rod 403 is activated, the second clamping plates 404 also move closer together, thus clamping and fixing the connecting rod. Once the handlebars and connecting rod are fixed, the bicycle can be started... The first motor 106 is driven, and a double-acting lead screw 104 is installed on the output shaft of the first motor 106. Two support seats 2 are installed on the surface of the double-acting lead screw 104, and both support seats 2 are engaged with the double-acting lead screw 104 through lead screw nuts 105. So when the double-acting lead screw 104 rotates, the two support seats 2 will move closer together. The first clamping plate 3 and the second clamping plate 404 are respectively installed on the top of the two support seats 2. So when the two support seats 2 move closer together, the handlebars and connecting rods will also move closer together, thereby achieving the purpose of assembly. The bottom of each of the second clamping plates 404 is equipped with a first electric push rod 201, which allows for height adjustment of the first clamping plate 3 and the second clamping plate 404. A slot 303 is formed on the clamping surface of the first clamping plate 3, and a roller 304 is installed inside the slot 303, making close contact with the handlebars. A second motor 308 is installed on the back side of the first clamping plate 3. When the handlebars require angle adjustment, the second motor 308 can be activated. A first synchronous belt 307 is installed on the output shaft of the second motor 308. The other end of 07 is connected to roller 304, so that when the second motor 308 is started, roller 304 can drive the handlebar to rotate, thereby achieving the purpose of angle adjustment. A second synchronous belt 408 is installed on one side of each of the two second clamping plates 404, and the other end of the second synchronous belt 408 is connected to the third motor 409, so that when the third motor 409 is started, the connecting rod can be angled to ensure that the handlebar can be stably assembled with the connecting rod. After the assembly is completed, it is welded by welding head 103.
