Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and more specifically, to a pin flipping mechanism. Background Technology

[0002] Chargers are ubiquitous in people's daily lives, becoming an indispensable consumer product. Chargers are manufactured using injection molding. Specifically, a robotic arm first inserts the charger's prongs into an injection mold, and then the mold performs injection molding to cover the prongs with a casing, thus forming the charger.

[0003] In current injection molding production, randomly stacked pins are typically vibrated and sorted before being fed horizontally. They are then picked up manually or by a robot and loaded into the injection molding machine. However, the pin positioning slots in injection molds are vertical, while the incoming material is horizontal. This necessitates additional manual labor or an additional pin-flipping module on the robot. When using manual labor, the operator must bend over every 2-3 seconds to stand up each horizontal pin and align it with the mold positioning slot, resulting in slow efficiency and hindering production. Using a four-axis robot is costly and rarely used in small-scale production. Furthermore, when pins are deformed, have burrs, or are slightly reversed, the robot cannot adapt, requiring manual intervention, thus increasing labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide a pin flipping mechanism that is compact, saves a lot of costs, and effectively improves production efficiency.

[0005] The technical solution adopted by the pin flipping mechanism disclosed in this utility model is:

[0006] A pin flipping mechanism includes a direct vibration feeding assembly, a conveying assembly, and a reversing assembly. The direct vibration feeding assembly includes a direct vibration body and a feeding channel. The feeding channel is used to receive pins and feed them out in a single row in a horizontal position. The reversing assembly is located at the output end of the feeding channel and has a clamping head that can rotate around its own axis. The clamping head is used to receive the pins and flip them from a horizontal position to a vertical position after the pins are in place. The conveying assembly is located on one side of the direct vibration feeding assembly and is used to clamp the pins in the vertical position and transfer them to the downstream receiving position.

[0007] As a preferred embodiment, the reversing assembly further includes a first rotary motor, the output shaft of which is connected to a clamping head. The clamping head is provided with a stepped platform, which is coplanar with one side of the feeding channel before flipping. After being flipped by the first rotary motor, the stepped platform is used to support the bottom of the insert.

[0008] As a preferred embodiment, the stepped platform is provided with a convex key, which is in clearance fit with the anti-reverse groove on the bottom surface of the pin.

[0009] As a preferred embodiment, the conveying assembly includes a linear drive module and a rotary clamping module. The linear drive module has a slider that reciprocates along the feeding direction of the linear vibration feeding assembly, and the rotary clamping module is fixedly installed on the slider.

[0010] As a preferred embodiment, the rotary clamping module includes a telescopic cylinder, a second rotary motor, and a gripper cylinder. The cylinder body of the telescopic cylinder is fixed to the slider, the output end of the telescopic cylinder is connected to the housing of the second rotary motor, the output shaft of the second rotary motor is fixedly connected to the gripper cylinder, and the output end of the gripper cylinder is provided with a gripper.

[0011] As a preferred embodiment, a clamping block is connected to one side of the pneumatic gripper, and an installation groove is provided on the inner side of the clamping block. When the gripper cylinder drives the pneumatic gripper to clamp, the clamping block engages the pin with the installation groove.

[0012] As a preferred embodiment, the feeding channel is formed by screwing a fixed base and a mounting plate together. The fixed base has a groove extending through the feeding direction on the side facing the mounting plate. The bottom surface of the groove is lower than the bottom surface of the feeding channel to accommodate the insulating part of the pin.

[0013] As a preferred embodiment, a viewing window is provided between the fixed base and the mounting plate to allow real-time observation of the posture and flow direction of the pins within the feeding channel.

[0014] As a preferred embodiment, the fixed base is provided with elongated holes symmetrically on both sides perpendicular to the feeding direction, and the mounting plate is adjustablely locked to the elongated holes by bolts.

[0015] As a preferred embodiment, a detection unit is also included, which is located at the end where the feeding channel connects to the reversing component.

[0016] The beneficial effects of the plug flipping mechanism disclosed in this utility model are as follows: the horizontal plug is accurately delivered to the flipping station through the straight vibration flow channel, the clamping head flips the plug from a horizontal posture to a vertical posture, and then the transport module directly picks up the vertical plug on the same baseline. The plug can automatically complete the entire process from horizontal feeding to 90-degree flipping and then to vertical transport without manual intervention or additional robotic arms. This significantly improves the automation level and production cycle of plug feeding and effectively enhances production efficiency. Attached Figure Description

[0022] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0023] Please refer to Figure 1 and Figure 2 A pin flipping mechanism includes a direct vibration feeding assembly 10, a conveying assembly 20, and a reversing assembly 30. The input end of the direct vibration feeding assembly 10 is connected to the output port of an external feeding vibratory feeder, and is used to convey the pins in a horizontal orientation to the reversing assembly 30. The reversing assembly 30 is used to rotate the pins conveyed by the direct vibration feeding assembly 10 by 90 degrees around its axis, so that they are flipped from a horizontal orientation to a vertical orientation. The conveying assembly 20 is disposed above the direct vibration feeding assembly 10, and is used to clamp the pins that have been turned by the reversing assembly 30, and to movably dock with an external product receiving mechanism.

[0024] In this embodiment, the pins transported by the pin flipping mechanism are conductive pins of electrical components, which have a metal part and an insulating part.

[0025] Please refer to Figure 3 The linear vibration feeding assembly 10 includes a base plate 11, a linear vibration body 12, and a feeding channel 13. The linear vibration body 12 is fixed to the base plate 11 by a shock-absorbing pad, and its output amplitude is adjustable. The feeding channel 13 is fixed above the linear vibration body 12. The inlet end of the feeding channel 13 is smoothly connected to the output port of the feeding vibratory plate, and the outlet end of the feeding channel 13 is precisely connected to the receiving position of the reversing assembly 30, forming a continuous conveying channel without breaks or steps, ensuring that the pins always maintain a horizontal posture and move in a single row under high-speed micro-vibration.

[0026] Please refer to Figure 4The feeding channel 13 consists of a fixed base 131 and a mounting plate 132. The fixed base 131 is fastened to one side of the mounting plate 132 by screws. The fixed base 131 is fixedly installed on the direct vibration body 12. The through cavity gap of the feeding channel 13 is slightly larger than the thickness of the horizontally placed plug, which can ensure that the plugs slide smoothly in sequence under the action of direct vibration, and also limit their vertical jumping to avoid flipping or jamming. The fixed base 131 is provided with a groove 1311. The bottom surface of the groove 1311 is lower than the bottom surface of the feeding channel 13 to accommodate the insulating part of the plug. When the plug is conveyed in the feeding channel 13, the insulating part of the plug is placed in the groove 1311 and moves, thereby ensuring that the plugs maintain a horizontal posture and consistent direction during the conveying process.

[0027] Preferably, a viewing window is provided between the fixed base 131 and the mounting plate 132. In operation, the posture and flow direction of the pins in the feeding channel 13 can be observed in real time through this window to realize visual defect early warning.

[0028] In another embodiment, the fixed base 131 and the mounting plate 132 adopt an adjustable mounting structure. The fixed base 131 is provided with elongated holes or waist-shaped holes on both sides perpendicular to the feeding direction. The mounting plate 132 is engaged with the elongated holes by bolts to change the gap size of the receiving cavity, thereby adapting to different specifications of pins.

[0029] Please refer to Figure 5 The reversing assembly 30 includes a clamping head 31 and a first rotary motor 32. The output shaft of the first rotary motor 32 is connected to the clamping head 31 to achieve controllable rotation. The free end of the clamping head 31 is provided with a clamping port 311. In this embodiment, the clamping port 311 is U-shaped, and its opening direction is directly opposite to the discharge direction of the feeding channel 13. It is used to receive the pins sent out by the output end of the feeding channel 13. When the pins are fully inserted into the clamping port 311, the first rotary motor 32 drives the clamping head 31 to rotate 90 degrees around its axis, so that the pins instantly flip from a horizontal posture to a vertical posture, providing a unified orientation reference for the precise material picking in the next step.

[0030] In this embodiment, the inner side of the clamping port 311 is provided with a stepped platform 312, the top surface of which forms a horizontal supporting surface. When the clamping head 31 is not rotated, this supporting surface is coplanar with the side of the groove 1311, ensuring that the pin slides smoothly into the clamping port 311 in a horizontal state without interference or obstruction. The stepped platform 312 is provided with a protruding key, which forms a clearance fit with the anti-reverse groove 1311 preset at the corresponding position of the pin insulation part, realizing the uniqueness of the pin insertion direction, preventing reverse insertion, and improving assembly reliability.

[0031] When the first rotary motor 32 drives the clamping head 31 to rotate 90 degrees, the stepped platform 312 synchronously rotates to the underside of the plug insulation part, and its supporting surface forms a rigid contact with the bottom surface of the insulation part, forming a stable fulcrum. This structure effectively suppresses the drooping or swaying of the plug due to its own weight, significantly enhances the positioning stability of the plug in the vertical posture, and provides a reliable position guarantee for the precise clamping of the subsequent handling component 20.

[0032] The fixed base 131 has a connecting block 14 on the side facing the reversing component 30. The upper surface of the connecting block 14 has a guide groove 141. The side and bottom surfaces of the guide groove 141 are coplanar with the side and bottom surfaces of the groove 1311 of the fixed base 131, respectively. Thus, when the pin slides out of the feeding channel 13, the metal part of the pin can continue to slide horizontally along the guide groove 141 until the insulating part of the pin is engaged in the clamping port 311 of the clamping head 31. When the first rotary motor 32 drives the clamping head 31 to rotate 90 degrees, the metal part of the pin can be disengaged from the connecting block 14 through the guide groove 141. The rotation process is smooth and without jamming, so that the subsequent handling component 20 can repeatedly and accurately grasp the pin, meeting the high positioning accuracy insertion process requirements.

[0033] A detection unit is provided at the end where the feeding channel 13 connects to the reversing assembly 30. This detection unit can be a photoelectric sensor, a proximity switch, or a vision recognition module, and the specific type can be selected according to the actual working conditions. Its output signal is used to control the start-up timing of the reversing assembly 30, preventing empty clamping or misoperation and improving system reliability.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 The conveying assembly 20 includes a linear drive module 21 and a rotary clamping module 22. The linear drive module 21 includes a drive motor 211, a slider 212, and a fixing plate 213. The output end of the drive motor 211 is connected to the slider 212. One side of the fixing plate 213 is fixed to the slider 212, and the other side of the fixing plate 213 is provided with a mounting hole 2131. The rotary clamping module 22 is fixedly installed on the surface of the slider 212 through the mounting hole 2131. The drive motor 211 is a servo motor or a stepper motor, which is linked to the linear guide rail via a synchronous belt or ball screw to drive the slider 212 to reciprocate along the feeding direction.

[0035] The rotary clamping module 22 includes a telescopic cylinder 221, a second rotary motor 222, and a gripper cylinder 223. The output end of the telescopic cylinder 221 is fixedly connected to the second rotary motor 222, and the output end of the rotary motor is fixedly connected to the gripper cylinder 223. The output end of the gripper cylinder 223 is equipped with a gripper 2231. During operation, the telescopic cylinder 221 drives the gripper cylinder 223 to move up and down. The gripper cylinder 223 drives the gripper 2231 to clamp or release the pin. The second rotary motor 222 drives the gripper cylinder 223 to rotate around its own axis, thereby driving the pin to rotate around its own central axis to match the directional requirements of different workstations on the material handling mechanism. Then, it is transported to the top of the product receiving mechanism by the linear drive module 21. The telescopic cylinder 221 descends again, accurately placing the pin that has been rotated into position into the corresponding workstation of the material handling mechanism. The gripper cylinder 223 releases, and then returns to its original position to pick up the next pin, completing one cycle.

[0036] In this embodiment, the pneumatic gripper 2231 is connected to clamping blocks 2232. Each of the two clamping blocks 2232 has a mounting groove milled on its opposite surface that complements the shape of the insert. The mounting groove can be V-shaped, rectangular, or other shapes. When the gripper cylinder 223 is vented and clamps, the two clamping blocks 2232 close synchronously, and the insert is precisely engaged in the mounting grooves on both sides, achieving self-centering positioning and preventing rotation or slippage.

[0037] The operator pours a batch of plugs into the external feeding mechanism, which arranges the bulk plugs into a horizontal position and feeds them into the feeding channel 13. The direct vibration body 12 drives the feeding channel 13 to vibrate continuously. The plugs move one by one in the feeding channel 13 to the clamping port 311 of the clamping head 31. When the first rotary motor 32 drives the clamping head 31 to rotate 90 degrees, the plug can be flipped from a horizontal position to a vertical position. The stepped platform 312 supports the lower end of the plug to prevent it from sagging or falling. The linear drive module 21 moves the rotary clamping module 22 above the clamping head 31 to clamp the plug. After clamping, the telescopic cylinder 221 is raised, and the linear drive module 21 transfers the plug to the downstream receiving position. The second rotary motor 222 can further adjust the plug angle to adapt to different receiving tooling. The overall production efficiency and automation level are high.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
