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.

[0015] (2) The assembly process incorporates elements of lean manufacturing, automation, and information technology to reduce the labor intensity of workers and improve production efficiency.

[0018] Preferably, the cylinder block assembly unit mainly consists of a cleaning and pre-assembly area, throttle-plug-taper pin installation, primary assembly tray area, parts distribution warehouse, automated assembly line, offline finishing area, safety protection system, electronic control system, and information management system. The cleaning and pre-assembly area and primary assembly tray area are mainly operated manually, and the products are pre-assembled and prepared in sequence. The parts distribution warehouse, automated assembly line, and offline finishing area are mainly operated automatically, with manual assistance for the cylinder block assembly operation.

[0019] Example 1 The automated assembly equipment has two fixed plates. Vertical blocks are fixedly connected to the upper ends of each fixed plate. Horizontal blocks are fixedly connected to the upper ends of each of the two sets of vertical blocks. Guide mechanisms are installed at the lower ends of each of the two sets of horizontal blocks. Moving plates are installed inside each of the guide mechanisms. Two connecting rods are fixedly connected to the lower ends of each of the two sets of moving plates. V-blocks are rotatably mounted on the lower ends of each of the two connecting rods. Stop rods are fixedly connected to the lower ends of each of the two moving plates, and these stop rods abut against the V-blocks. A vertical rod is installed on the upper end of the V-block away from the stop block. A spring is fixedly connected to one side of the vertical rod, and the spring is fixedly connected to the stop rod on the side away from the vertical rod. An infrared lamp is fixedly connected to the lower end of one of the horizontal blocks. A pulling mechanism for pulling the moving plate is installed at the lower end of the horizontal block. An assembly mechanism is installed at the upper end of each fixed plate. A conveying mechanism for conveying cylinder seats is installed between the two fixed plates. The guide mechanism includes two sets of sliding... The system comprises two sets of slide rails fixedly connected to a horizontal block. A slider is slidably mounted on the outer wall of each slide rail. The two sets of sliders are fixedly connected to a moving plate. The pulling mechanism includes two sets of connecting blocks, each fixedly mounted to the lower end of the middle of the horizontal block. An electric push rod is fixedly connected to the lower end of each connecting block. The two sets of electric push rods are installed in opposite directions, and their telescopic ends are fixedly connected to the sliders. The conveying mechanism includes two conveying rollers, each rotatably mounted to a fixed plate. A conveyor belt is driven onto the outer wall of each conveying roller. A drive motor is mounted on one side of one of the fixed plates, and the output shaft of the drive motor is fixedly connected to the rotating shaft of the conveying roller. Support legs are fixedly connected to the lower ends of both fixed plates, and multiple sets of support legs are arranged in a rectangular array. The assembly mechanism includes a mounting platform, fixedly connected to one of the fixed plates. A robotic arm body is mounted on the upper end of the mounting platform.

[0020] In the technical solution of this invention, the conveying mechanism can transport the cylinder seat. When the cylinder seat is transported to the infrared lamp, the conveying mechanism can stop transporting. The pulling mechanism can pull the moving plate to move with the cooperation of the guiding mechanism. Then, when the V-block under the moving plate contacts the cylinder seat, it can center the cylinder seat, thereby cooperating with the assembly mechanism for assembly. After the cylinder seat is assembled, the pulling mechanism can drive the moving plate to move, and the V-block releases its limit on the cylinder seat. Then, the spring drives the V-block to reset, and the stop rod can limit the stop block, so that the conveying mechanism can transport the cylinder seat, thus speeding up the assembly efficiency of the cylinder seat.

[0021] In addition, the horizontal block can fix the slider, and the slider can slide on the slide rail, which in turn facilitates the slide rail to guide the moving plate. The horizontal block can fix the connecting block, and the connecting block can fix the electric push rod, which can drive the slider to move.

[0022] In the technical solution of the present invention, the assembly mechanism includes a mounting platform, which is fixedly connected to one of the fixing plates. The upper end of the mounting platform is equipped with a robotic arm body. The fixing plate can fix the mounting platform, and the mounting platform can install the robotic arm body. The robotic arm body can perform assembly operations on the cylinder seat.

[0023] In the technical solution of the present invention, the conveying mechanism includes two conveying rollers, which are rotatably mounted on a fixed plate. Conveyor belts are driven and mounted on the outer walls of the two conveying rollers. The fixed plate can provide rotational support for the conveying rollers. The cooperation between the conveying rollers and the conveyor belts can convey the cylinder seat. A drive motor is mounted on one side of one of the fixed plates. The output shaft of the drive motor is fixedly connected to the rotating shaft of the conveying roller. The drive motor can drive the conveying roller to rotate. Support legs are fixedly connected to the lower ends of the two fixed plates. Multiple sets of support legs are arranged in a rectangular array. The support legs can provide support for the fixed plates.

[0024] In operation, the drive motor first rotates the conveyor rollers, which, in conjunction with the conveyor belt, transport the cylinder seat. When the cylinder seat is below the infrared lamp, the drive motor stops, and the electric push rod pulls the slider, which in turn moves the moving plate. The slider slides outside the slide rail, which guides the moving plate, allowing the V-block to contact the cylinder seat. Upon contact, the V-block pulls the spring, facilitating the adjustment of the V-block's angle for center positioning of the cylinder seat. This allows the robotic arm to assemble the cylinder seat. After assembly, the pulling mechanism moves the moving plate, releasing the V-block from its limit position on the cylinder seat. The spring then resets the V-block, and the stop bar limits the stop block, allowing the conveyor mechanism to transport the cylinder seat, thus accelerating the assembly process.

[0025] Example 2 The automatic assembly table includes a worktable, a positioning plate fixedly connected to the upper end of the worktable, side plates fixedly connected to both sides of the positioning plate, a first cylinder fixedly mounted on the upper end of the worktable, a moving plate fixedly connected to the telescopic end of the first cylinder, the moving plate corresponding to the position of the positioning plate, an assembly mechanism rotatably mounted on the upper end of the worktable, and a rotating mechanism for rotating the assembly mechanism provided at the lower end of the worktable, a linkage mechanism provided between the rotating mechanism and the first cylinder; a rotating table is provided inside the assembly mechanism, and a gear is provided inside the rotating mechanism, the gear being fixedly connected to the rotating table; the linkage mechanism includes a gas cylinder, the gas cylinder being fixed to the worktable. The gas cylinder is installed with a first connecting pipe and a second connecting pipe fixedly installed at its two output ends. The side of the first connecting pipe away from the gas cylinder is fixedly installed with a first cylinder, and the side of the second connecting pipe away from the gas cylinder is fixedly installed with a second cylinder. The second cylinder is fixedly connected to a gear plate, which meshes with a gear. The lower end of the worktable is fixedly connected with multiple sets of legs arranged in a rectangular array. The rotating table is rotatably installed on the worktable. The upper end of the rotating table is fixedly installed with a rotating bracket, and a robotic arm is installed on one side of the rotating bracket. The gear is rotatably installed on the lower end of the worktable and is fixedly connected to the rotating table. The lower end of the worktable is fixedly installed with a second cylinder.

[0026] In the technical solution of the present invention, the rotating mechanism can drive the assembly mechanism to rotate. Then, when the rotating mechanism rotates, it can drive the first cylinder to move the moving plate with the cooperation of the linkage mechanism. The moving plate can position the cylinder seat with the cooperation of the positioning plate and the side. The assembly mechanism can perform operations on the cylinder seat, thereby achieving the function of semi-automatic assembly of the cylinder seat and speeding up the assembly efficiency of the cylinder seat assembly.

[0027] In addition, the worktable can provide rotational support for the rotary table, which in turn can rotate the rotating bracket, thereby facilitating the rotation of the robotic arm and enabling the robotic arm to perform assembly operations on the cylinder seat.

[0028] In the technical solution of the present invention, the rotating mechanism includes a gear, which is fixedly connected to the rotating shaft of the rotating table and slidably connected to the lower end of the worktable. The rotating shaft of the rotating table can connect the gear. A second cylinder is fixedly connected to the lower end of the worktable.

The worktable can fix the second cylinder, and the second cylinder can drive the gear to move, while the toothed plate can drive the gear to rotate.

[0029] In the technical solution of this invention, the linkage mechanism includes a gas cylinder, which is fixedly installed on a worktable. The worktable can fix the gas cylinder. A first connecting pipe is installed on one side of the gas cylinder. The side of the first connecting pipe away from the gas cylinder is fixedly installed on a first cylinder. The gas cylinder can fix the first connecting pipe, and the first connecting pipe can connect the first cylinder and the gas cylinder, thereby facilitating the gas cylinder to ventilate the first cylinder. A second connecting pipe is fixedly installed on the side of the gas cylinder away from the first connecting pipe. The second connecting pipe is fixedly installed on a second gas cylinder, and the second connecting pipe can connect the second cylinder and the gas cylinder, and ventilate both the gas cylinder and the second cylinder.

[0030] In the technical solution of the present invention, the lower end of the workbench is fixedly connected to multiple sets of legs, which are arranged in a rectangular array to support the workbench.

[0031] In operation, the second cylinder first moves the gear plate, which in turn rotates the gears. The gears then rotate the rotating platform, which in turn rotates the rotating bracket and the robotic arm. When the robotic arm rotates above the positioning plate, the second cylinder retracts, which, in conjunction with the second connecting pipe, inflates the gas cylinder. The gas from the gas cylinder fills the first connecting pipe and the first gas cylinder, causing the first gas cylinder to move the moving plate. This allows the moving plate, positioning plate, and side plate to position the cylinder seat, facilitating the robotic arm's assembly of the cylinder seat. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
