[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] Refer to Figure 1-4 As shown, the embodiment of the utility model provides a pre-tightening seat belt piston structure assembly machine, which is installed on a corresponding frame, including a vibration plate, a mechanical clamp A1, a mechanical clamp B2, and a feeding mechanism. The vibration plate is used for feeding the piston. The feeding mechanism includes a feeding box cover 3 and a feeding box 4. The feeding box cover 3 is installed on the feeding box 4. The surface of the feeding box cover 3 is provided with a rod opening. The feeding box 4 is used to accommodate a steel ball. The bottom of the feeding box 4 is a hemispherical concave surface, and a concave portion 5 is provided at the center of the concave surface. The concave part 5 is in the shape of an inverted truncated cone, and a ball delivery rod 6 is provided at the center of the concave part 5. The ball delivery rod 6 is movably provided in the loading box 4 and the loading box cover 3. The bottom of the ball delivery rod 6 is connected to the cylinder, and the cylinder is used to adjust the height position of the ball delivery rod 6. A plurality of steel ball holes are provided on the surface of the ball delivery rod 6, and the plurality of steel ball holes are used to collect steel balls. The mechanical clamp A1 is used to clamp the piston delivered by the vibration plate, and the steel ball is pressed into the piston after the piston is placed on the ball delivery rod 6. The mechanical clamp B2 is used to grab the piston with the steel ball.
[0024] When in use, the piston is fed into the mold at the end in an orderly manner through the vibration plate, and the mechanical clamp A1 clamps the piston sent by the vibration plate and moves the piston to the top of the feeding mechanism. The ball feeding rod 6 is located at the lowest position of the recess 5, and the steel balls in the feeding box 4 are gathered to the position of the ball feeding rod 6 through the concave surface and the recess 5, and finally roll and fall on the steel ball hole of the ball feeding rod 6. At this time, the ball feeding rod 6 is raised by adjusting the cylinder, and the ball feeding rod 6 passes through the rod mouth and protrudes from the feeding box cover 3. The surface of the piston has multiple plastic strips, and a certain interval is left between each plastic strip. The plastic strip is Y-shaped. The mechanical clamp A1 places the piston on the ball feeding rod 6 and applies pressure. When pressure is applied, the plastic strip is deformed, so that the steel ball is conveniently inserted between the plastic strips. The installation operation of the steel ball and the piston is completed. After the installation is completed, the mechanical clamp A1 resets and continues to clamp the next piston. At the same time, the ball feeding rod 6 resets to the recess 5 to continue collecting steel balls, and the mechanical clamp B2 grabs the piston with the steel ball and moves it to the specified position.
[0025] Refer to Figure 5 As shown, the mechanical clamp A1 includes a slide cylinder A11, a lifting cylinder A12, a rotary cylinder A13, and a pneumatic clamp A14. The slide cylinder A11 is used to adjust the position movement of the lifting cylinder A12, the rotary cylinder A13, and the pneumatic clamp A14. The lifting cylinder A12 is used to adjust the movement of the rotary cylinder A13 and the pneumatic clamp A14. The rotary cylinder A13 is used to adjust the rotation of the pneumatic clamp A14.
[0026] When in use, the slide cylinder A11 adjusts the lifting cylinder A12, the rotary cylinder A13, and the pneumatic clamp A14 to move in the direction of the vibration plate. After reaching the specified position, the lifting cylinder A12 adjusts the pneumatic clamp A14 to descend to grab the piston. After the grabbing is completed, the pneumatic clamp A14 is reset to the initial height, and the slide cylinder A11 adjusts the lifting cylinder A12, the rotary cylinder A13, and the pneumatic clamp A14 to reset. After resetting, the pneumatic clamp A14 is above the feeding mechanism. When the ball feeding rod 6 extends out of the feeding box cover 3 with the steel ball, the lifting cylinder A12 descends with the pneumatic clamp A14 to press the steel ball into the piston.
[0027] Refer to Figure 6 As shown, the mechanical clamp B2 includes a slide cylinder B15, a lifting cylinder B16, a rotary cylinder B17, and a pneumatic clamp B18. The slide cylinder B15 is used to adjust the position movement of the lifting cylinder B16, the rotary cylinder B17, and the pneumatic clamp B18. The lifting cylinder B16 is used to adjust the position movement of the rotary cylinder B17 and the pneumatic clamp B18. The rotary cylinder B17 is used to adjust the rotation of the pneumatic clamp B18.
[0028] When in use, the slide cylinder B15 adjusts the lifting cylinder B16, the rotary cylinder B17, and the pneumatic clamp B18 to move in the direction of the upper material mechanism. The lifting cylinder B16 adjusts the rotary cylinder B17 and the pneumatic clamp B18 to descend and grab the piston with the steel ball, and then reset to the initial position. During the resetting process, the piston with the steel ball is flipped by the rotary cylinder B17. When it returns to the initial position, the flipping adjustment is completed, and then the lifting cylinder B16 is descended to put the piston with the steel ball after the flipping is completed into the corresponding mold opening below.
[0029] Refer to Figure 1 , 3 As shown in , 7 and 8, the assembly machine also includes a steel ball storage mechanism, which includes a feed box 7, a hopper 8 and a ball feeding plate 9. The hopper 8 is connected to the feed box 7, and the ball feeding plate 9 is movably arranged on the inner side of the feed box 7, and the bottom of the feed box 7 is inclined, inclined toward the position of the ball feeding plate 9, and the bottom of the ball feeding plate 9 is connected to the cylinder, and the cylinder is used to adjust the lifting of the ball feeding plate 9. The upper end of the ball feeding plate 9 is provided with a ball feeding groove 10, and the ball feeding groove 10 is inclined. Joints are provided on the steel ball storage mechanism and the feeding mechanism, and the joints are used to connect pipelines. The steel ball storage mechanism is connected to the feeding mechanism through pipelines;
[0030] During use, steel balls are manually poured into the hopper 8, and the steel balls fall into the feeding box 7. Because the bottom of the feeding box 7 is an inclined structure, the steel balls gather to one side, that is, where the ball feeding plate 9 is located, and some steel balls are located in the ball feeding groove 10 of the ball feeding plate 9. When the cylinder lifts the ball feeding plate 9, the ball feeding plate 9 is lifted together with the steel balls in the ball feeding groove 10, until the ball feeding plate 9 is lifted to the specified height, the steel balls can use the ball feeding groove 10 to tilt and fall into the joint of the steel ball storage mechanism, and then use the pipeline to enter the feeding mechanism.
[0031] Refer to Figure 5 As shown, the assembly machine also includes a vision collector. After the mechanical clamp A1 clamps the piston, it will move to the position of the vision collector through the slide cylinder A11. The vision collector is located below the piston and is used to collect actual image information of the piston clamped by the mechanical clamp A1, fit and compare the actual image information with the preset image information of the piston, and obtain correction data of the actual image information and the preset image information of the workpiece. The correction data is the rotation angle. The mechanical clamp A1 rotates the piston according to the correction data using the rotary cylinder A13 to adjust its angle, so that the piston after moving to the position of the steel ball is aligned with the position of the steel ball, and the steel ball can be accurately inserted into the piston.
