In the prior art, a gripper structure is usually used to grasp the pressure relief valve parts. However, the gripper gripping method is complex in structure, and the position of the positioning hole needs to be positioned during gripping, which reduces the efficiency of gripping and installation and increases the cost of use. There is a need for improvement. Utility Model Content

[0010] The present invention is further configured such that the drive component uses a servo motor.
[0011] In summary, this utility model has the following beneficial effects:
[0012] 1. By setting a rotating seat on the base and a vacuum positioning adsorption seat on the rotating seat, and a laser sensor on the base, the pressure relief valve cover is positioned and vacuum adsorbed onto the vacuum positioning adsorption seat. A laser is emitted onto the pressure relief valve cover. After the laser is emitted and reflected off the surface of the pressure relief valve cover, it is received by the laser sensor and the reflection time is calculated. The rotating seat and the vacuum positioning adsorption seat are rotated by a drive motor, which in turn drives the pressure relief valve cover adsorbed on the vacuum positioning adsorption seat to rotate. When the positioning hole rotates to the position of the laser sensor, the time interval between the laser reflection and the laser sensor increases, thereby achieving positioning of the positioning hole on the pressure relief valve cover. The structure is simple, and positioning is achieved by rotating the pressure relief valve cover after suction. The positioning efficiency is high, which increases the installation efficiency.
[0013] 2. By setting a vacuum adsorption chamber inside the vacuum adsorption positioning seat, and by setting a first vacuum adsorption groove on the inner adsorption seat and a second vacuum adsorption groove between the outer positioning seat and the inner adsorption seat, the adsorption stability of the vacuum positioning adsorption seat is increased by increasing the vacuum adsorption area. By setting a buffer component, the pressure relief valve cover is installed inside the pressure relief valve to achieve buffering and avoid damage to the pressure relief valve.

The vacuum positioning adsorption seat 5 has several vacuum adsorption chambers 6 for adsorbing the pressure relief valve cover 7. A laser sensor 9 for positioning the positioning hole 8 is connected to the base 1. By positioning the pressure relief valve cover 7 and vacuum adsorbing it onto the vacuum positioning adsorption seat 5, a laser is emitted onto the pressure relief valve cover 7. After the laser is emitted and reflected off the surface of the pressure relief valve cover 7, it is received by the laser sensor 9 and the reflection time is calculated. The rotating seat 2 and the vacuum positioning adsorption seat 5 are driven by a drive motor to rotate, thereby driving the pressure relief valve cover 7 adsorbed on the vacuum positioning adsorption seat 5 to rotate. When the positioning hole 8 rotates to the position of the laser sensor 9, the time interval between the laser reflection and the laser sensor 9 increases, thereby achieving the positioning of the positioning hole 8 on the pressure relief valve cover 7. In this embodiment, four sets of buffer components 4 are evenly arranged along the circumferential direction between the rotating seat 2 and the vacuum positioning adsorption seat 5, and the driving component 3 uses a servo motor.
[0023] refer to Figure 2 and Figure 3Specifically, the vacuum positioning adsorption seat 5 includes an outer positioning seat 51 coaxially disposed at the bottom of the rotating seat 2 and an inner adsorption seat 52 coaxially fixedly connected inside the outer positioning seat 51. A positioning groove 53 is provided on the outer side of the outer positioning seat 51 away from the rotating seat 2 for fitting against the inner wall of the pressure relief valve cover 7. A mating hole 54 is provided on the bottom of the inner adsorption seat coaxially for cooperating with the pressure relief pipe on the pressure relief valve cover 7. The pressure relief valve cover 7 is coaxially positioned on the vacuum positioning adsorption seat 5 through the cooperation of the positioning groove 53 and the positioning hole 8. An inclined positioning surface 65 is provided on the end of the positioning groove 53 and the positioning hole 8 away from the rotating seat 2 to facilitate positioning.
[0024] refer to Figure 2 and Figure 4 Specifically, the vacuum adsorption chamber 6 includes a first vacuum adsorption groove 61 vertically opened on the inner adsorption seat 52 and a second vacuum adsorption groove 62 disposed between the outer positioning seat 51 and the inner adsorption seat 52. A connecting groove 63 is opened in the inner adsorption seat 52 to connect the first vacuum adsorption groove 61 and the second vacuum adsorption groove 62. A vacuum tube 64 connected to the connecting groove 63 is fixedly connected to the top of the inner adsorption seat 52. By increasing the vacuum adsorption area, the adsorption stability of the vacuum positioning adsorption seat 5 is increased.
[0025] refer to Figure 2 and Figure 5 Specifically, the buffer assembly 4 includes a mounting sleeve 41 fixedly connected to the rotating seat 2 in the vertical direction and a buffer rod 42 fixedly connected to the vacuum positioning adsorption seat 5 in the vertical direction. A sliding groove 43 for accommodating the buffer rod 42 is coaxially opened in the mounting sleeve 41. A buffer spring 44 is fixedly connected in the sliding groove 43. When the pressure relief valve cover 7 is installed in the pressure relief valve, the buffer spring 44 is compressed to achieve buffering and avoid damage to the pressure relief valve.
[0026] Brief description of the usage process: The pressure relief valve cover 7 is positioned and vacuum-adsorbed onto the vacuum positioning adsorption seat 5. A laser is emitted onto the pressure relief valve cover 7. After the laser is emitted and reflected off the surface of the pressure relief valve cover 7, it is received by the laser sensor and the reflection time is calculated. The drive motor drives the rotating seat 2 and the vacuum positioning adsorption seat 5 to rotate, thereby driving the pressure relief valve cover 7 adsorbed on the vacuum positioning adsorption seat 5 to rotate. When the positioning hole 8 rotates to the position of the laser sensor, the time interval between the laser reflection and the laser sensor increases, thereby achieving the positioning of the positioning hole 8 on the pressure relief valve cover 7. After positioning, the pressure relief valve cover 7 is installed into the pressure relief valve.
