Description

Technical Field

[0001] This utility model relates to the field of injection molded part assembly technology, specifically an automatic orientation assembly device. Background Technology

[0002] Injection molding, as a highly efficient and precise manufacturing technology, has been widely used in the field of medical devices. Through injection molding, complex-shaped and finely structured medical device components can be produced, meeting the high requirements of the medical industry for product quality and performance.

[0003] Currently, some medical device components require the insertion and installation of two sets of injection molded parts. To simplify the installation process, a mechanized processing mode is usually adopted to insert and install a large number of the two injection molded parts. The two injection molded parts are injection molded part A and injection molded part B. During assembly, injection molded part A is inserted into injection molded part B. Injection molded part B is clamped on the worktable using a fixture. Injection molded part A is fed by a vibrating feeding tray. Then, a gripper is used to grip injection molded part A and insert it into injection molded part B. However, due to the orientation of the assembly between injection molded part A and injection molded part B, and the randomness of the feeding, it is difficult to ensure that the installation direction of injection molded part A is consistent with the installation direction of injection molded part B after the fixture picks up the material. After injection molded part A is inserted into injection molded part B, subsequent inspection or secondary adjustment is required, which increases the assembly process and thus reduces the overall installation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic orientation assembly device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic orientation assembly device includes: a movable component disposed on a moving mechanism, the movable component being capable of picking up inserts; The moving part is provided with a material picking component, the material picking component is provided with a steering component, the steering component includes a material picking component rotatably connected to the moving part, and a steering component is fixedly provided on the material picking component; The moving part is equipped with a positioning component and a driving component. When the picking component picks up the plug-in, the positioning component is triggered. The driving component can cooperate with the steering component to drive the picking component to rotate the plug-in. During the rotation, after the plug-in rotates to a preset position, the positioning component is activated to position the plug-in.

[0006] The automatically oriented assembly equipment as described above: the material handling component includes a suction head, which is rotatably connected to the moving component.

[0007] The automatic orientation assembly equipment described above: the steering component includes a rotating component fixedly arranged coaxially with the suction head, the rotating component having multiple sets of composite grooves equidistantly formed along the circumferential direction of the suction head, the driving component cooperating with the composite grooves, and being able to drive the rotating component to rotate the suction head relative to the moving component.

[0008] The automatic orientation assembly equipment as described above: the composite groove includes a first vertical surface and a second vertical surface formed on the rotating member, and the second vertical surface is arranged along the tangential direction of the rotating member.

[0009] The automatic orientation assembly equipment as described above: the driving component includes an air nozzle, which is fixedly mounted on the moving component and is arranged along the tangential direction of the rotating component.

Detailed Implementation

[0018] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0019] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0020] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0021] Please see Figures 1-5 In this embodiment of the present invention, an automatic orientation assembly device includes: a movable component 6 disposed on a moving mechanism 3, the movable component 6 being capable of picking up the insert component 8; Specifically, please refer to Figure 1 The aforementioned moving mechanism 3 is installed inside the housing 1, which contains a turntable 4 and a feeding table 2. The turntable 4, the feeding table 2, and the moving mechanism 3 are controlled by a control system installed inside the housing 1 and perform intermittent actions.

[0022] In detail, the turntable 4 is fixedly provided with multiple sets of clamping members 5 at equal intervals along its circumference. The clamping members 5 are used to clamp and fix the injection molded part 7. The feeding table 2 can continuously feed the plug-in part 8 into the machine box 1. After the feeding table 2 feeds the plug-in part 8 once, the moving mechanism 3 will drive the moving part 6 to perform an action: first, the plug-in part 8 on the feeding table 2 is attracted to the moving part 6, and then the plug-in part 8 is inserted and installed with the injection molded part 7 on the clamping member 5.

[0023] After the insertion and installation are completed, the turntable 4 will rotate the next clamping part 5 to the installation position (i.e., the position where the insertion part 8 and the clamping part 5 are inserted and installed), and wait for the moving part 6 to perform the insertion operation of the insertion part 8.

[0024] It should be further noted that the position of the injection molded part 7 remains fixed. When rotated to the installation position, the orientation of the semi-circular structure on the injection molded part 7 remains consistent so that the subsequent connector 8 can be inserted into the injection molded part 7. When the connector 8 is inserted into the injection molded part 7, the semi-circular structure of the connector 8 and the semi-circular structure of the injection molded part 7 should be completely overlapped.

[0025] The moving part 6 is provided with a material picking component, and the material picking component is provided with a steering component. The steering component includes a material picking component that is rotatably connected to the moving part 6, and a steering component is fixedly provided on the material picking component. The moving part 6 is provided with a positioning component and a driving component. When the picking component picks up the plug 8, the positioning component is triggered. The driving component can cooperate with the steering component to drive the picking component to rotate the plug 8. During the rotation, after the plug 8 rotates to a preset position, the positioning component is activated to position the plug 8. The material handling component includes a suction head 10, which is rotatably connected to the moving component 6; Specifically, please refer to Figures 1-5 The suction head 10 is connected to the negative pressure mechanism (not shown in the figure) provided on the moving part 6. When the moving mechanism 3 drives the moving part 6 to move toward the feeding table 2, the control system drives the negative pressure mechanism to enter the working state, which can drive the suction head 10 to adsorb the plug-in part 8 on the feeding table 2 onto the moving part 6. At this time, the plug-in part 8 and the suction head 10 are fixedly connected, so that the moving mechanism 3 can drive the suction head 10 to complete the plug-in installation between the plug-in part 8 and the injection molded part 7.

[0026] The steering component includes a rotating component 11 that is coaxially fixed to the suction head 10. The rotating component 11 has multiple sets of composite grooves equidistantly arranged along the circumferential direction of the suction head 10. The driving component cooperates with the composite grooves and can drive the rotating component 11 to drive the suction head 10 to rotate relative to the moving component 6. The composite groove includes a first vertical surface 1101 and a second vertical surface 1102 formed on the rotating member 11, and the second vertical surface 1102 is arranged along the tangential direction of the rotating member 11. The driving component includes an air nozzle 9, which is fixedly mounted on the moving component 6 and is arranged along the tangential direction of the rotating component 11. Preferably, please refer to Figure 5The composite grooves are arranged in five sets at equal intervals along the circumference of the rotating member 11, and the first vertical surface 1101 and the second vertical surface 1102 form a notch structure of a "right angle". In summary, once the suction head 10 has stabilized its adsorption on the connector 8, and the moving component 6, driven by the moving mechanism 3, moves away from the feeding table 2, the control system will drive the air nozzle 9 to eject high-pressure gas. Subsequently, the high-pressure gas acts on the first vertical surface 1101, driving the rotating component 11 to rotate the suction head 10 counterclockwise (see reference). Figure 4 , Figure 5 (Description), at the same time, the connector 8 rotates synchronously with the suction head 10 until the connector 8 rotates to the preset position. Then, the positioning component will position the connector 8 by blocking, so that the connector 8 and the injection molded part 7 are positioned. At this time, the high-pressure gas ejected by the nozzle 9 will not be able to drive the rotating part 11 to rotate. The gas ejected by the nozzle 9 will dissipate outward along the direction of the first vertical surface 1101 and the second vertical surface 1102 until the connector 8 and the injection molded part 7 are connected. Then, the control system issues a stop command to the nozzle 9 so that the nozzle 9 stops ejecting high-pressure gas outward.

[0027] For details, please refer to Figures 1-5 The positioning component includes a mounting bracket 601 fixedly mounted on the movable part 6. A plug tube 12 is fixedly mounted on the mounting bracket 601. A spring 14 is provided inside the plug tube 12. One end of the spring 14 abuts against the mounting bracket 601, and the other end abuts against the plug rod 13 provided inside the plug tube 12. Specifically, the spring 14 is in a compressed state. In the compressed state, the spring 14 pushes the plug rod 13 to move towards the outside of the plug tube 12. In the initial state, the plug rod 13 protrudes the plug tube 12 to the maximum length, and the lower end of the plug rod 13 is lower than the semi-circular structure of the plug member 8.

[0028] In summary, during the actual transport of the connector 8, the feeding platform 2 can only ensure that the semi-circular structure on the connector 8 faces the moving part 6, but cannot guarantee that the semi-circular structure of the connector 8 adsorbed by the suction head 10 completely overlaps with the semi-circular structure of the injection molded part 7 on the mounting position; therefore, during the downward insertion and suction of the suction head 10, the connector rod 13 will experience two situations: Scenario 1: The semi-circular structure of the connector 8 pushes the connector rod 13 to retract into the connector cylinder 12 (at this time, the elastic potential energy stored in the spring 14 is less than the negative pressure attraction generated by the suction head 10, so that the connector 8 can still maintain a fixed connection with the suction head 10 when the connector rod 13 is retracted). Subsequently, as the control system controls the nozzle 9 to spray high-pressure gas, driving the rotating component 11 to rotate the suction head 10 counterclockwise, the insertion rod 13 slides on the semi-circular structure of the insertion component 8 until the insertion rod 13 separates from the semi-circular structure. At this point, the spring 14 releases its elastic potential energy, pushing the insertion rod 13 back to its initial position. As the rotating component 11 and the suction head 10 continue to rotate, when the contact surface 801 of the insertion component 8 contacts the insertion rod 13, the positions of the rotating component 11 and the suction head 10 are fixed. At this time, the insertion component 8 rotates to a preset position so that the insertion component 8 can be inserted and installed with the injection molded part 7.

[0029] Scenario 2: The semi-circular structure of the connector 8 is offset from the connector rod 13. At this time, the connector rod 13 remains unchanged in its initial state. Subsequently, as the control system controls the nozzle 9 to spray high-pressure gas, driving the rotating part 11 and the suction head 10 to rotate counterclockwise, the contact surface 801 of the plug-in part 8 will gradually come into contact with the plug-in rod 13. Then, under the restriction of the plug-in rod 13, the plug-in part 8 is maintained in the preset position so that the plug-in part 8 can be plugged into and installed with the injection molded part 7.
