[0043] In combination Figure 1 As shown, the present embodiment provides an electromagnetic valve gas circuit board automatic production line, which comprises a transmission roller 100 and an electromagnetic valve gas circuit board auxiliary clamping tool 200. The transmission roller 100 is arranged in a rectangular annular structure. Opposite sides of the transmission roller 100 are provided with a ladder that spans the transmission roller 100 (not labeled in the figure). The ladder facilitates the operator to enter the inner area of the transmission roller 100 from the outer area of the transmission roller 100, so as not to affect the transmission operation of the transmission roller 100. The inner area is provided with a robot 300 and a clamp library (not shown in the figure). The robot 300 is used for material turnover. The middle of one side of the other opposite sides of the transmission roller 100 is provided with a plurality of loading and unloading stations.

[0045] Further, the peripheral area of the conveying roller 100 is provided with several processing devices, and each processing device is provided with a machine tool clamp loading and unloading mechanism (not shown in the figure) at the connection with the conveying roller 100 for mounting the accompanying sub-clamp 2 on the conveying roller 100 to the machine tool clamp in the processing device. Specifically, the processing device is a processing machine tool, and the machine tool clamp (not shown in the figure) is provided in the processing machine tool and matched with the accompanying sub-clamp 2 clamping the workpiece to be processed and conveying on the conveying roller 100. When loading, the accompanying sub-clamp 2 is conveyed to the front end of the processing machine tool, and a blocking cylinder is provided on the conveying roller 100 to limit the forward movement of the accompanying sub-clamp 2 to keep it at the loading point. A clamp lifting cylinder (not shown in the figure) is provided below the loading point of the conveying roller 100, and the output end of the clamp lifting cylinder is connected to a clamp lifting plate to lift the accompanying sub-clamp 2 off the conveying roller 100. The accompanying sub-clamp 2 is transferred to the machine tool clamp by the gripper located above the machine tool clamp and the loading point. The degree of automation is high, and no manual operation is required. Since the machine tool clamp loading and unloading mechanism is prior art, it will not be described in detail here.

[0046] The existing method is to manually clamp the workpiece to be processed on the accompanying sub-clamp, convey the accompanying sub-clamp on the roller to make the workpiece to be processed reach the processing station of each device, and clamp the sub-clamp connected to the mother clamp of each device for processing. Among them, manual clamping needs to ensure the position accuracy of the workpiece, which requires high technical requirements for personnel and takes a lot of time. In addition, only the length direction of the same type of workpiece has differences, and the length difference is only 10 mm, which leads to the possibility of clamping the wrong workpiece during manual loading.

The accompanying sub-clamp 2 comprises a fixed chuck 21 and a movable chuck 22 oppositely arranged along a second direction, and a workpiece to be processed is clamped between the fixed chuck 21 and the movable chuck 22. The baffle 3 is slidably arranged on the base plate 1 along a first direction perpendicular to the second direction, and one side of the workpiece to be processed abuts against the side wall of the baffle 3. The laser range finder 4 is arranged on the base plate 1 in a sliding manner along the second direction and is spaced apart from the baffle 3.

[0049] In addition, the laser range finder 4 measures two fixed points on the end face of each workpiece to be processed, and judges whether the workpiece to be processed is incorrectly assembled according to the distance data of the two measured points. When the measured distance deviates from the data recorded in the system, the laser range finder 4 sends a signal to the controller, and the controller controls the alarm device to issue a warning to inform the operator of the mistake, and the laser range finder 4 with two points can judge the type of the workpiece to be processed and the correctness of the placement state of the workpiece to be processed, reducing the possibility of incorrectly assembling the workpiece to be processed by manual feeding.

The movable part 222 with a corresponding length is installed on the fixed part 221 according to different types of workpieces to be machined, so that the distance between the movable part 222 and the fixed chuck 21 can be adjusted adaptively, and the universality is good. The protrusion 2221 is arranged on the movable part 222 in the embodiment, and the groove 2211 is formed in the fixed chuck 21, and the protrusion 2221 of the movable part 222 is inserted into the groove 2211, so that the structure is simple and convenient to assemble and disassemble.
