[0036] Reference Figure 1, an automatic loading and unloading injection molding machine, comprising: a machine platform 100, a storage bin 200, a feeding mechanism 300, a discharging mechanism 400 and a conveying mechanism 500; the storage bin 200 is arranged on the machine platform 100, the storage bin 200 is used to store terminals, and the storage bin 200 is provided with a discharge port; the feeding mechanism 300 is arranged on the machine platform 100, and the feeding mechanism 300 can drive at least one terminal in the storage bin 200 to move through the discharge port; the feeding mechanism 300 can drive the terminal to move to the discharging mechanism 400; the discharging mechanism 400 includes a detection component 350 and an arrangement component 330, the detection component 350 is used to detect the terminal, and the arrangement component 330 is used to arrange and place the terminal; the conveying mechanism 500 is arranged on the machine platform 100, and the conveying mechanism 500 is used to drive the terminal at the arrangement component 330 to move to the injection mold. The terminals are stored in the storage bin 200. Therefore, when the terminals need to be loaded, the loading mechanism 300 can be directly moved to the discharge port of the storage bin 200 to drive the terminals to move, which can effectively achieve the effect of obtaining the terminals. After the loading mechanism 300 drives the terminals to leave the storage bin 200, the terminals can be driven to the arrangement component 330 first. Repeat this action, and multiple terminals can be arranged outside the storage bin 200 in a predetermined arrangement. In this process, the detection component 350 can detect the terminal's own state or arrangement state, thereby improving the quality of the finished product. Subsequently, the arranged terminals can be transported together through the conveying mechanism 500, thereby achieving the effect of orderly loading of the terminals. Since the loading of the terminals before injection molding is achieved by the cooperation of the loading mechanism 300, the discharge mechanism 400 and the conveying mechanism 500, and the storage effect of the storage bin 200 on the terminals also makes the terminal retrieval process more convenient and faster, the loading operation speed can be effectively improved, and then the efficiency of the injection molding of the terminals can be effectively improved.

[0037] In certain embodiments, reference Figure 4 The storage bin 200 is tubular, and the discharge port is arranged at the end of the storage bin 200; the feeding mechanism 300 includes a material shifting assembly 310 arranged in the storage bin 200, and at least part of the material shifting assembly 310 extends into the storage bin 200 and can drive each terminal to the discharge port one by one. The tubular storage bin 200 can not only effectively store multiple terminals, but also make the terminals stored in the storage bin 200 distributed and arranged along the length direction of the storage bin 200, so that it is convenient for the material shifting assembly 310 to drive each terminal to the discharge port one by one, thereby facilitating the subsequent components to take the terminal.

[0038] Specifically, the storage bin 200 is a magazine-like straight tube. Of course, the storage bin 200 can also be in other shapes, such as a box shape. The specific implementation method is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

[0039] In certain embodiments, reference Figure 3 The material-digging assembly 310 includes a material-digging seat 315 and a linear drive module 317. The storage bin 200 is provided with a passage 210. Part of the material-digging seat 315 passes through the passage 210 and extends into the storage bin 200. The linear drive module 317 is connected to the material-digging seat 315 and can drive it to reciprocate in the passage 210. The linear drive module 317 can drive the material-digging seat 315 to reciprocate in the storage bin 200. Therefore, the part of the material-digging seat 315 that passes through the passage 210 and extends into the storage bin 200 can move in the storage bin 200, thereby driving the terminal to move to the discharge port, thereby facilitating the subsequent components to take the terminal at the discharge port.

[0040] In certain embodiments, reference Figure 6 The feeding mechanism 300 includes a flip assembly 320 disposed at the discharge port, and the flip assembly 320 can drive the terminal to rotate to the arrangement assembly 330 and adjust the relative orientation of the terminal and the arrangement assembly 330. The flip assembly 320 can drive the terminal at the discharge port to flip, and the flipping action not only allows the terminal to move to the arrangement assembly 330, but also can adjust the orientation angle of the terminal, thereby ensuring that the terminal can adapt to the change in the orientation angle between the discharge port and the arrangement assembly 330, thereby making the terminal feeding operation more smoothly.

[0041] In certain embodiments, reference Figure 7 The flip assembly 320 includes a support frame 321, a two-axis displacement platform 322 and a mounting seat 323. The mounting seat 323 is connected to the support frame 321 through the two-axis displacement platform 322. The mounting seat 323 is provided with a flip drive cylinder 324 and a cylinder clamp 325. The flip drive cylinder 324 is connected to the cylinder clamp 325 and can drive it to flip relative to the mounting seat 323. After the two-axis displacement platform 322 on the support frame 321 drives the mounting seat 323 to move to the discharge port, the flip drive cylinder 324 can drive the cylinder clamp 325 to dock with the discharge port, so that the cylinder clamp 325 can take out the material discharged from the discharge port. After that, the two-axis displacement platform 322 and the flip drive cylinder 324 can respectively drive the cylinder clamp 325 to displace and flip, so that the terminal can be displaced to the arrangement assembly 330 in the correct direction, so that the arrangement assembly 330 can arrange the terminals.

[0042] Specifically, the two-axis displacement platform 322 is connected to two mounting seats 323, and both mounting seats 323 are provided with a flip driving cylinder 324 and a cylinder clamp 325. The two mounting seats 323 synchronously convey terminals of different orders, thereby effectively improving the conveying efficiency.

[0043] In certain embodiments, reference Figure 2 The arrangement component 330 includes a transfer box 335 and a paddle 332 disposed on the machine 100. The feeding mechanism 300 can drive the terminal to move to the transfer box 335 or the paddle 332; the paddle 332 is connected to the arrangement cylinder 331 and can push multiple terminals to move and arrange. When the detection component 350 detects that the terminal is in an unqualified state, the flip component 320 can drive the terminal to move to the transfer box 335, otherwise, the terminal moves to the paddle 332, and the paddle 332 arranges each terminal under the drive of the arrangement cylinder 331, thereby effectively achieving the purpose of arranging each terminal.

[0044] In certain embodiments, reference Figure 7 The detection assembly 350 includes a detection probe 335 disposed beside the transfer box 335. The detection probe 335 is located between the storage bin 200 and the transfer box 335 and can detect the terminal. When the flip assembly 320 drives the terminal to move, the terminal will pass through the detection area of ​​the detection probe 335. The detection probe 335 can detect the shape of the terminal or whether it is in place at this time, so that unqualified terminals can be transported to the transfer box 335 in time for easy discharge.

[0045] In certain embodiments, reference Figure 8 and Fig. 9 The discharge mechanism 400 further includes a recursive pusher assembly 420 and a discharge chute 440. The transport mechanism 500 can drive the terminals in the transfer box 335 to move to the recursive pusher assembly 420; the recursive pusher assembly 420 can load multiple terminals and drive each terminal to enter the discharge chute 440 together. After the detection assembly 350 detects the terminal, if it is determined that the terminal is unqualified, the terminal will be driven into the transfer box 335. Afterwards, the transport mechanism 500 will move to the transfer box 335 and drive the terminals in the transfer box 335 to move to the discharge chute 440, so as to timely remove the unqualified terminals.

[0046] Specifically, there are multiple discharge chutes 440, and the machine 100 is provided with multiple recycling boxes 450, each of which is connected to a corresponding recycling box 450, so that terminals with different reasons for failure can be classified and recycled through different recycling boxes 450. A linear displacement platform 410 is provided on the machine 100, and the recursive assembly 420 is provided on the linear displacement platform 410 and moves between each discharge chute 440.

[0047] Furthermore, the reciprocating assembly 420 includes a reciprocating cylinder 423 and a supporting material box 425. The supporting material box 425 is used to load a plurality of terminals, and the supporting material box 425 has area divisions. After the conveying mechanism 500 conveys the terminals to the supporting material box 425, the reciprocating cylinder 423 can drive the supporting material box 425 to move to the discharge chute 440, so that the terminals in the supporting material box 425 can fall into the discharge chute 440.

[0048] In certain embodiments, reference Figure 1 The transport mechanism 500 includes a manipulator disposed on the machine platform 100, the manipulator is connected to a clamp and can drive the terminal to move through it. The manipulator can directly and effectively clamp the terminal through the clamp and drive the terminal to move, so as to smoothly achieve the purpose of transporting the material.

[0049] In certain embodiments, reference Figure 1 There are multiple feeding mechanisms 300, and the fixture is provided with multiple clamping stations. Each feeding mechanism 300 can convey the terminal to different clamping stations on the fixture. Each feeding mechanism 300 can convey the terminal to different clamping stations of the fixture, so that the fixture can quickly clamp multiple terminals, thereby effectively improving the conveying efficiency of the manipulator to the terminal and the injection molding efficiency of the terminal.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
