[0034] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0035] The present invention will now be described in detail with reference to the accompanying drawings.
[0036] like Figures 1 to 3 As shown, this utility model discloses a wire injection molding inspection line, comprising a body 1. The body 1 is equipped with a feeding mechanism 2, an injection molding machine 3, an inspection machine 4, a screening mechanism 5, and a fixture return mechanism 6. The feeding mechanism 2 and the fixture return mechanism 6 work together to form a transmission loop for transporting the fixture. The feeding mechanism 2 is used to transfer the fixture loaded with wire to the injection molding machine 3. The injection molding machine 3 is used to inject the wire loaded in the fixture. The inspection machine 4 is used to inspect the injected wire. The screening mechanism 5 is used to remove the inspected wire from the fixture and screen it to distinguish between good and defective products. The fixture return mechanism 6 is used to transfer the fixture loaded with wire to the feeding mechanism 2, and to transfer the fixture after removing the wire from the feeding mechanism 2 to the fixture return mechanism 6.
[0037] During operation, the feeding mechanism 2 transfers the jig loaded with wire to the injection molding machine 3. Two injection molding machines 3 are arranged side by side, allowing them to simultaneously inject wire into two jigs, improving injection efficiency. Next, the inspection machine 4 inspects the injected wire, and the screening mechanism 5 removes the inspected wire from the jig and screens it to distinguish between good and defective products. Finally, the empty jig after removing the wire is transferred from the feeding mechanism 2 to the jig return mechanism 6. Simultaneously, an external feeding robot loads the empty jig placed in the jig return mechanism 6, causing the jig return mechanism 6 to transfer the wire-loaded jig back to the feeding mechanism 2 for a new round of production. This utility model has a compact and reasonable structure, forming an efficient material conveying loop between the various mechanisms, which is beneficial for overall control and management, and improves production efficiency.
[0038] The screening mechanism 5 in this embodiment includes a first robotic arm 51, a second robotic arm 52 spaced apart from the first robotic arm 51, an NG (non-compliant) collection device 53 used in conjunction with the second robotic arm 52, and a first driver 54 drivenly connected to the first robotic arm 51 and the second robotic arm 52. The first driver 54 drives the first robotic arm 51 and the second robotic arm 52 to move back and forth between the feeding mechanism 2 and the fixture return mechanism 6, so that the first robotic arm 51 takes the wire from the fixture and transfers the wire to the inspection machine 4, and the second robotic arm 52 takes the wire from the inspection machine 4 and transfers the wire to the NG collection device 53. Specifically, the first driver 54 is a conventional linear module, specifically a synchronous belt type linear module. Its working principle is that the belt is installed on the drive shafts on both sides of the linear module, and a slider for adding equipment or workpiece is fixed on the belt. The slider moves by driving the belt. The synchronous belt type linear module can select the number of loads according to actual work requirements, and can also add rigid guide rails to improve the rigidity of the linear module. Thus, the first robot 51, the second robot 52, and the third robot are equipped with three sliders on the belt for synchronous movement. The first driver 54 drives the first robot 51 and the second robot 52 to move back and forth between the feeding mechanism 2 and the fixture return mechanism 6, so that the first robot 51 takes the wire from the fixture and moves the wire to the inspection machine 4, and the second robot 52 takes the wire from the inspection machine 4 and moves the wire to the NG product collection device 53.
[0039] The first robotic arm 51 and the second robotic arm 52 in this embodiment have the same structure. The first robotic arm 51 includes a base 511, a support frame 512 movably disposed on the base 511, a clamping cylinder 513 disposed on the support frame 512, a clamping arm 514 driven and connected to the clamping cylinder 513, and a first lifting cylinder 515 driven and connected to the support frame 512. The first driver 54 is driven and connected to the base 511. Multiple clamping cylinders 513 are provided, and the multiple clamping cylinders 513 are arranged in a rectangular array. Specifically, the first actuator 54 drives the first robotic arm 51 to move closer to the feeding mechanism 2, and the first lifting cylinder 515 drives the carrier frame 512 to move downward, causing the clamping cylinder 513 mounted on the carrier frame 512 to move closer to the fixture. The clamping cylinder 513 drives the clamping arm 514 to close and pick up the wire. Then, the first lifting cylinder 515 drives the carrier frame 512 to move upward, and the first actuator 54 drives the first robotic arm 51 to move to the testing machine 4, and places the wire in the testing machine 4 for a series of electrical performance tests, including but not limited to contact resistance testing, insulation resistance testing, withstand voltage testing, DC resistance testing, etc. The second robotic arm 52 refers to the above operating steps of the first robotic arm 51 to remove the wire from the testing machine 4 and transfer the wire to the NG product collection device 53.
[0040] The NG (Not Found) item collection device 53 of this embodiment includes a movable base 531, a pickup cylinder 532 disposed on the movable base 531, a pickup arm 533 driven and connected to the pickup cylinder 532, and a second driver 534 driven and connected to the movable base 531. The pickup cylinder 532 picks up NG items from the second robotic arm 52 via the pickup arm 533, so that the second driver 534 moves the NG items out to an external NG item bin. Specifically, the second driver 534 is a prior art linear module. The second driver 534 drives the pickup cylinder 532 to move closer to the second robotic arm 52, the pickup cylinder 532 drives the pickup arm 533 to close and pick up the NG items from the second robotic arm 52, and then the second driver 534 moves the NG items out to an external NG item bin, where the NG items are collected and stored, improving the NG item pickup efficiency.
[0041] The fixture return mechanism 6 of this embodiment includes a first conveyor belt 61 and a first transfer device 62 and a second transfer device 63 respectively disposed at both ends of the first conveyor belt 61. The first transfer device 62 is used to transfer the fixture loaded with wire from the fixture return mechanism 6 to the feeding mechanism 2. The second transfer device 63 is used to transfer the unloaded fixture from the feeding mechanism 2 to the fixture return mechanism 6. The first transfer device 62 and the second transfer device 63 have the same structure. The first transfer device 62 includes a frame 621, a third driver 622 disposed on the frame 621, a lifting seat 623 movably disposed on the frame 621, a pneumatic finger 624 disposed on the lifting seat 623, a gripper 625 driven and connected to the pneumatic finger 624, and a second lifting cylinder 626 driven and connected to the lifting seat 623. The third driver 622 is driven and connected to the second lifting cylinder 626. Specifically, the first transfer device 62 is used to transfer the fixture loaded with wire from the fixture return mechanism 6 to the feeding mechanism 2, and the second transfer device 63 is used to transfer the unloaded fixture from the feeding mechanism 2 to the fixture return mechanism 6. Since the first transfer device 62 and the second transfer device 63 have the same structure and the same working principle, the second lifting cylinder 626 drives the pneumatic finger 624 to move downward through the lifting seat 623. The pneumatic finger 624 drives the gripper 625 to close to accurately clamp both sides of the fixture, thereby raising or lowering the fixture and effectively transferring the fixture back and forth between the fixture return mechanism 6 and the feeding mechanism 2.
[0042] The feeding mechanism 2 in this embodiment includes a second conveyor belt 21 and a material sensor 22 disposed on the second conveyor belt 21. The material sensor 22 is located above the second conveyor belt 21, which is spaced apart from and parallel to the first conveyor belt 61. Specifically, since the material sensor 22 is located above the second conveyor belt 21, when the second conveyor belt 21 moves the fixture forward, the material sensor 22 senses and detects the presence of the fixture, thereby sending a detection signal to the control system. The control system then controls the injection molding machine 3 and the inspection machine 4 to perform subsequent injection molding and inspection operations, resulting in high detection accuracy.
[0043] In this embodiment, the machine body 1 is equipped with a control system and a control panel 7 electrically connected to the control system. The feeding mechanism 2, injection molding machine 3, inspection machine 4, screening mechanism 5, and fixture return mechanism 6 are all electrically connected to the control system. Specifically, the feeding mechanism 2, injection molding machine 3, inspection machine 4, screening mechanism 5, and fixture return mechanism 6 are all electrically connected to the control system. The operator can trigger the control panel 7 to enable the control system to efficiently regulate the operating parameters of each mechanism, enhancing the ease of operation.
