[0014] The application provides a working method of a full-automatic injection molding component assembling machine, which comprises the following steps:

[0015] S1, the horizontal drive cylinder drives the horizontal support plate to move along two parallel straight-line guides, so that the product rotating platform moves out of the product insert press-fitting device;

[0016] S2, the injection molding components are placed on the two product insert press-fitting devices by manual or mechanical hands;

[0017] S2-1, the injection molding component is placed on the upper end face of the upper rotating disc, so that the injection molding component is sleeved on the product positioning column, and the injection molding component edge insert placing hole is placed at the positions of the three insert positioning assemblies, so that the upper end part of the product positioning insert is located in the injection molding component edge insert placing hole;

[0018] S2-2, the clamping drive cylinder is started, and the product pressing plate is pushed to rotate around the hinged support base, so that one end of the product pressing plate is pressed on the edge of the injection molded part;

[0019] S3, the horizontal drive cylinder drives the horizontal support plate to move along the two parallel straight linear guides, so that the product rotating platform moves to below the product insert pressing device;

[0020] S4, the insert vibrating disc is started, so that the inserts are orderly conveyed into the insert conveying belt;

[0036] By developing a full-automatic installation equipment, the original complex installation and cutting gate process becomes simple and clear, greatly shortens the installation time, saves the labor cost of the company, ensures the product yield and quality, greatly reduces the product scrap rate. The competitiveness of the product in the market is greatly improved.

[0037] The technical scheme can achieve the beneficial effects that the full-automatic assembling machine for injection molding parts can fully ensure accurate positioning of incoming materials by using a vibrating disc, and can place products on a jig with high precision by using a six-axis manipulator, and the work station needs the manipulator to place parts on the fixed jig. An integrated system for installing a bushing is arranged above the jig to complete conveying of the bushing to a fixed position, and a cylinder impacts the bushing into the injection molding part. Finally, a mechanical arm completes grabbing and placing on a flow line. The technical route needs to solve a series of complex program matching, thereby greatly improving production efficiency, effectively reducing cost, and making the product have obvious price advantage in fierce market competition.

8. A working method for a fully automatic injection molding assembly machine, characterized in that: Includes the following steps: S1. The horizontal drive cylinder (32) drives the horizontal support plate (34) to move along two parallel linear guide rails (33), so that the product rotating platform (4) moves out of the product insert pressing device (5); S2. Place the injection molded parts (100) on both product insert pressing devices (5) manually or by robotic arms. S2-1, The injection molded part (100) is placed on the upper end face of the upper rotating disk (472), so that the injection molded part (100) is fitted on the product positioning post (474), and at the same time, the edge insert placement hole of the injection molded part (100) is placed at the position of the three insert positioning components (475), so that the upper end of the product positioning insert (4752) is located in the edge insert placement hole of the injection molded part (100); S2-2, The clamping drive cylinder (481) is started, pushing the product pressure plate (484) to rotate around the hinge support seat (483), so that one end of the product pressure plate (484) is pressed against the edge of the injection molded part (100); S3, the horizontal drive cylinder (32) drives the horizontal support plate (34) to move along two parallel linear guide rails (33), so that the product rotating platform (4) moves to below the product insert pressing device (5); S4. The insert vibratory feeder (6) is started, so that the inserts (200) are neatly conveyed into the insert conveyor belt (7); S5. Initially, the piston rod of the conveyor block drive cylinder (86) is in the extended state, so that the U-shaped groove (841), the rectangular opening (852) and the insert conveyor belt (7) on the conveyor block (84) are connected, and the insert (200) on the insert conveyor belt (7) enters the U-shaped groove (841) through the rectangular opening (852); S6. The piston rod of the conveyor block drive cylinder (86) retracts, causing the conveyor block (84) to move on the conveyor block sliding seat (85). When the U-shaped groove (841) is aligned with the through hole (853), the insert (200) in the U-shaped groove (841) falls into the through hole (853). S7. Initially, the insert placement hole (831) and the through hole (853) are on the same straight line and are connected. Therefore, the insert (200) passes through the through hole (853) and falls into the insert placement hole (831). Since the insert placement hole (831) is tapered and the diameter of the lower end of the insert placement hole (831) is smaller than the diameter of the insert (200) in the normal state, the insert (200) is confined within the insert placement hole (831). S8. The piston rod of the push block drive cylinder (82) extends and pushes the push block (83) to move above the edge of the injection molded part (100) until the insert (200) and the product positioning insert (4752) are on the same straight line. S9. The piston rod of the gate punching drive cylinder (531) extends out, driving the gate punching insert (532) to move towards the injection molded part (100) until the gate punching insert (532) extends into the through hole of the injection molded part (100), and the punching tip (538) contacts the sprue on the inner wall of the through hole of the injection molded part (100), thereby punching off the sprue on the injection molded part (100); S10, the piston rod of the stamping drive cylinder (521) extends, driving the insert stamping rod (522) to descend, so that the lower end of the insert stamping rod (522) contacts the insert (200); S11, the positioning protrusion (523) extends into the inner hole of the insert (200), and the step four (524) contacts the upper end face of the insert (200); S12, the piston rod of the stamping drive cylinder (521) continues to extend, pushing the insert (200) in the insert placement hole (831) to move downward in the insert placement hole (831). Since there is an opening on the side wall of the annular insert (200), and since the diameter of the lower end of the insert placement hole (831) is smaller than the diameter of the insert (200) in its normal state, when the insert (200) moves to the lower end of the insert placement hole (831), the insert (200) is squeezed, which reduces the opening distance on the insert (200) and makes the diameter of the insert (200) smaller than the diameter of the lower end of the insert placement hole (831). S13. As the piston rod of the stamping drive cylinder (521) continues to extend, the insert (200) is pushed out of the insert placement hole (831), and the lower end of the insert (200) first enters the edge insert placement hole of the injection molded part (100); S14. When the insert (200) is pressed into place by the insert stamping rod (522), and the insert (200) contacts the product positioning insert (4752), the insert (200) and the product positioning insert (4752) move downward synchronously, and the positioning insert spring (4753) is compressed. When the product positioning insert (4752) touches the return signal switch (4754), the insert (200) is installed in place, and the gate punching drive cylinder (531) and the stamping drive cylinder (521) are reset to prepare for the next installation. At this time, the insert (200) is pressed into place at the first position of the injection molded part (100). S15, the motor (41) starts, and through the transmission belt (43), the driving transmission gear (44) and the driven transmission gear (45), the cam divider (46) works, driving the lower rotating disk (471) and the upper rotating disk (472) to rotate 120°; S16. Repeat steps S4 to S14 above to press the insert (200) into the second position of the injection molded part (100). S17, the motor (41) starts, and through the transmission belt (43), the driving transmission gear (44) and the driven transmission gear (45), the cam divider (46) works, driving the lower rotating disk (471) and the upper rotating disk (472) to rotate 120°; S18. Repeat steps S4 to S14 above to press the insert (200) into the third position of the injection molded part (100). S19. The horizontal drive cylinder (32) drives the horizontal support plate (34) to move along two parallel linear guide rails (33), so that the product rotating platform (4) moves out of the product insert pressing device (5). The injection molded part (100) with three inserts (200) installed is removed by manual or robotic arm, and two injection molded parts (100) to be assembled are placed on it again, and the above pressing is repeated.
