Description

Technical Field

[0001] This utility model relates to the field of vibratory feeder technology, and in particular to a charger PIN guide device for vibratory feeders. Background Technology

[0002] In the charger manufacturing industry, especially for Indian-standard chargers targeting the Indian market, the PIN pin structure has specific design characteristics. The PIN pin is cylindrical in shape, with a rounded end for insertion into a socket; the other end has a contact terminal, the radius of which is smaller than the radius of the cylinder, primarily for connecting to the charger's internal circuitry. To ensure a secure installation of the PIN pin within the charger housing, a horizontal notch is provided near the contact terminal, forming a locking mechanism that reliably secures the PIN pin. With the continuous development and maturation of automation technology in manufacturing, automated production has become a trend in the in-mold injection molding of charger housings and PIN pins. However, in current production practices, there is still significant room for improvement in the positioning and feeding process of the PIN pin during in-mold injection molding.

[0003] In existing technologies, when PIN guide pins are in-mold molded with the charger housing, they are mainly positioned manually into pre-set fixtures. A robotic arm then clamps the positioned PIN guide pins into the mold to complete the in-mold molding process. This manual positioning method is not only inefficient but also makes it difficult to guarantee positioning accuracy, severely impacting production quality and schedule, and failing to meet the demands of large-scale automated production. To achieve automatic PIN guide pin feeding, the industry typically uses vibratory feeders for directional feeding. As a common automatic feeding device, the vibratory feeder uses vibration to move materials along a specific trajectory, thereby achieving directional material output. During the PIN guide pin feeding process, a simple guiding structure allows the vibratory feeder to guide the PIN guide pins out with the rounded end facing forward or the contact end facing forward.

[0004] However, for the PIN guides of Indian standard chargers, due to their special structure, after simply achieving the orientation of the guides with the round head facing forward or the power receiving end facing forward, subsequent mechanisms such as robotic arms are still needed to correct the PIN guides that are in the wrong orientation. This undoubtedly increases the complexity of the automation device. At the same time, due to the lack of an effective screening mechanism, even if a correction mechanism is set up later, the frequent handling of PIN guides in the wrong orientation will lead to a significant reduction in the operating efficiency of the entire feeding system and an increase in the equipment failure rate.

[0005] Therefore, how to design a directional feeding structure that can perform high-precision screening of the two different directions of the PIN pins of Indian standard chargers, so as to realize the automated and precise feeding of the PIN pins, has become a technical problem that urgently needs to be solved in the current charger manufacturing field. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] A PIN guide device for a charger used in a vibratory feeder includes an aligning device installed inside the vibratory feeder and connected to the feeder's discharge position. The aligning device includes a feeding channel, a defective product discharge channel, a good product discharge channel, and a good product discharge track. One end of the feeding channel receives a cylindrical workpiece and guides it to the other end through vibration. The other end of the feeding channel has a dropping area extending along its side. A flat opening is provided in the dropping area, and two ends of the flat opening are respectively provided with electrical terminal clearance openings. Two guide ramps are provided below the flat opening, with their upper ends connected and corresponding to the middle position of the flat opening. The defective product discharge channel and the good product discharge channel are respectively connected to the lower ends of the two guide ramps. The good product discharge track is connected to the lower end of the good product discharge channel. The defective product discharge channel is inclined so that its lower end is within the vertical projection area of ​​the good product discharge track.

[0008] Preferably, the two ends of the flat opening are arc-shaped structures, and the power connection end extends along the middle position of the end of the flat opening.

[0009] Preferably, the feeding channel has a supporting bottom surface and a blocking side surface that are angled together. The supporting bottom surface has an inclination so that the columnar workpiece abuts against the supporting bottom surface and the blocking side surface after entering the feeding channel. The unloading area has an extended bottom surface that extends to the side along the end of the supporting bottom surface and a bent side surface that bends the end of the blocking side surface to form a bent side surface around the edge of the extended bottom surface. A flat opening is opened on the extended bottom surface.

[0010] Preferably, the cross-sections of the defective product unloading chute, the good product unloading chute, and the good product discharge track are all arc-shaped structures capable of supporting the cylindrical workpiece.

[0011] Preferably, a first crossbar is fixed at the lower end of the feeding trough. The first crossbar is connected to the flat opening. The first crossbar has a cube or prismatic structure. The two guide slopes are the two adjacent sides of the upper part of the first crossbar. The defective product feeding trough and the good product feeding trough are connected to the two sides of the lower part of the first crossbar.

[0012] Preferably, the feeding trough, the defective product unloading trough, and the good product unloading trough are all welded and fixed to the first crossbar, so that the feeding trough, the defective product unloading trough, and the good product unloading trough are fixed inside the vibratory feeder by the first crossbar; multiple second crossbars are also welded to the lower end of the good product discharge track, and the good product discharge track is fixed inside the vibratory feeder by the second crossbars.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By utilizing the difference in the center of gravity between the PIN pin's electrical terminal and its rounded head, combined with the matching design of the clearance openings at both ends of the flat opening, PIN pins of different orientations fall in different directions due to gravity. This achieves high-precision screening without a complex drive structure, cleverly solving the problem of traditional vibratory feeders' inability to distinguish between PIN pins of two different orientations. Simultaneously, the guide ramp guides the separated PIN pins into their corresponding feeding slots, ensuring the orderly separation of PIN pins of the correct and incorrect orientations. This improves the accuracy and efficiency of directional feeding, providing a reliable guarantee for subsequent automated in-mold injection molding production.

Detailed Implementation

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figure 1-4 In this embodiment of the present invention, a charger PIN guiding device for a vibratory feeder includes an aligning device installed inside the vibratory feeder 10 and connected to the discharge position of the vibratory feeder 10. The aligning device includes a feeding channel 20, a defective product discharge channel 30, a good product discharge channel 40, and a good product discharge track 50. One end of the feeding channel 20 receives a cylindrical workpiece and guides the cylindrical workpiece to the other end of the feeding channel 20 by vibration. The other end of the feeding channel 20 has a discharge area 60 extending along the side, and the discharge area 60 is provided with... It has a flat opening 61, and two ends of the flat opening 61 are respectively provided with electrical terminal clearance openings 62. Two guide slopes 71 are provided below the flat opening 61. The upper ends of the two guide slopes 71 are connected and correspond to the middle position of the flat opening 61. The defective product discharge trough 30 and the good product discharge trough 40 are respectively connected to the lower ends of the two guide slopes 71. The good product discharge track 50 is connected to the lower end of the good product discharge trough 40. The defective product discharge trough 30 is inclined so that the lower end of the defective product discharge trough 30 is located in the vertical projection area of ​​the good product discharge track 50.

[0025] When the vibratory feeder 10 is working, it transports the PIN needles to the feeding channel 20, which guides them to the dropping area 60 through vibration. The flat opening 61 of the dropping area 60 matches the cylindrical shape of the PIN needle. When the PIN needle moves forward with its rounded end towards the flat opening 61, its electrical terminal connects to the electrical terminal clearance opening 62 at the rear of the flat opening 61. Due to the larger center of gravity on one side of the electrical terminal, the PIN needle falls backward onto the corresponding guide slope 71 under the influence of gravity. When the PIN needle moves backward with its rounded end towards the flat opening 61, its electrical terminal connects to the electrical terminal clearance opening 62 at the front of the flat opening 61. Similarly, due to the larger center of gravity on one side of the electrical terminal, the PIN needle falls forward onto the other guide slope 71. The upper ends of the two guide ramps 71 are connected to the middle of the flat opening 61, guiding the PIN pins falling in different directions to the corresponding defective product discharge trough 30 and good product discharge trough 40 at the lower end, respectively, to achieve precise separation between the two. The PIN pins falling into the good product discharge trough 40 will eventually fall into the good product discharge track 50 and be sent out of the vibratory feeder 10 along with the good product discharge track 50, while the PIN pins falling into the defective product discharge trough 30 will eventually fall back into the vibratory feeder 10.

[0026] This device utilizes the difference in center of gravity between the PIN pin's electrical contact end and the round head, combined with the matching design of the electrical contact ends of the flat opening 61 and the clearance opening 62, to allow PIN pins of different orientations to fall in different directions through gravity. This achieves high-precision screening without a complex drive structure, cleverly solving the problem of traditional vibratory feeders 10's inability to distinguish between PIN pins of two different orientations. Simultaneously, the guide ramp 71 guides the separated PIN pins into their corresponding feeding slots, ensuring the orderly separation of PIN pins of the correct and incorrect orientations. This improves the accuracy and efficiency of directional feeding, providing a reliable guarantee for the subsequent automated production of in-mold injection molding.

[0027] Please see Figure 3-4 Based on the above technical solution, it is further proposed that the two ends of the flat opening 61 are arc-shaped structures, and the power receiving end clearance opening 62 extends along the middle position of the end of the flat opening 61. The arc-shaped structure can make the PIN needle enter the flat opening 61 more smoothly, reduce the jamming or sticking caused by the collision of sharp corners, improve the smoothness of the movement of the PIN needle in the material dropping area 60, and reduce the risk of material supply interruption caused by material jamming. The power receiving end clearance opening 62 extends along the middle position of the end of the flat opening 61, which can more accurately match the power receiving end of the PIN needle, ensuring that the power receiving end of the PIN needle can be accurately embedded in the clearance opening, whether the round head is facing forward or backward. This avoids abnormal PIN needle posture caused by the position deviation of the clearance opening, further improves the recognition and screening accuracy of PIN needles in both directions, ensures the stability and consistency of subsequent good product output, and thus better meets the needs of directional PIN needle feeding.

[0028] Please see Figure 1 Based on the above technical solution, it is further proposed that the feeding channel 20 has a support bottom surface 21 and a blocking side surface 22 that are angled together. The support bottom surface 21 has an incline so that the columnar workpiece abuts against the support bottom surface 21 and the blocking side surface 22 after entering the feeding channel 20. The unloading area 60 has an extended bottom surface 63 that extends to the side along the end of the support bottom surface 21 and a bent side surface 64 that bends the end of the blocking side surface 22 to form a side surface 64 around the edge of the extended bottom surface 63. A flat opening 61 is opened on the extended bottom surface 63. The feeding channel 20 adopts a support bottom surface 21 and a blocking side surface 22 that are angled together, and the support bottom surface 21 has an incline. This design allows the columnar PIN needle to naturally abut against the support bottom surface 21 and the blocking side surface 22 after entering the feeding channel 20. The cooperation of the two achieves the initial limiting and guiding of the PIN needle, effectively preventing the PIN needle from being blocked. During the conveying process, the needles may deviate, flip, or stack, ensuring they move stably along the feeding channel 20, laying a good foundation for subsequent screening operations. Simultaneously, the discharge area 60 is equipped with an extended bottom surface 63 extending to the side along the end of the supporting bottom surface 21, and a bent side surface 64 forming a bend around the edge of the extended bottom surface 63, created by bending the end of the blocking side surface 22. This structure allows the PIN needles conveyed from the feeding channel 20 to smoothly transition to the discharge area 60. The bent side surface 64 further restricts the range of motion of the PIN needles in the discharge area 60, preventing them from falling off the edge of the extended bottom surface 63. This ensures that the PIN needles can accurately enter the flat opening 61 on the extended bottom surface 63, significantly improving the positioning accuracy of the PIN needles in the discharge area 60. This, in turn, enhances the reliability and stability of the entire device in PIN needle direction screening, better meeting the needs of automated directional feeding.

[0029] Please see Figure 1-2 Based on the above technical solutions, it is further proposed that the cross-sections of the defective product unloading trough 30, the good product unloading trough 40, and the good product discharge track 50 are all arc-shaped structures capable of supporting the cylindrical workpiece. The arc-shaped structure can form a good fit with the outer surface of the cylindrical PIN pin, increasing the contact area between the two, thereby providing more stable support for the PIN pin during the conveying process, effectively preventing the PIN pin from shifting, flipping, or jamming when falling or sliding, and ensuring the smoothness of the conveying process. At the same time, this arc-shaped fit structure can reduce rigid collisions and friction between the PIN pin and the channel and track, reducing the risk of scratches, deformation, and other damage to the PIN pin surface, and protecting the structural integrity and appearance quality of the PIN pin. In addition, the stable conveying state further improves the reliability and continuity of the entire directional feeding process, providing higher quality PIN pin raw materials for subsequent in-mold injection molding and other processes, and better meeting the requirements of automated production for workpiece conveying accuracy and stability.

[0030] Please see Figure 1-2Based on the above technical solution, it is further proposed that a first crossbar 70 be fixed at the lower end of the feeding channel 20, the first crossbar 70 be connected to the flat opening 61, the first crossbar 70 be a cube or prismatic structure, and the two guide slopes 71 be the two adjacent sides of the upper part of the first crossbar 70. The defective product unloading channel 30 and the good product unloading channel 40 are connected to the two sides of the lower part of the first crossbar 70. The feeding channel 20, the defective product unloading channel 30 and the good product unloading channel 40 are all welded and fixed to the first crossbar 70, so that the feeding channel 20, the defective product unloading channel 30 and the good product unloading channel 40 are fixed inside the vibrating plate 10 by the first crossbar 70. At the lower end of the good product discharge track 50, multiple second crossbars 80 are also welded, and the good product discharge track 50 is fixed inside the vibrating plate 10 by the second crossbars 80. The first crossbar 70 has a cube or prismatic structure, with its two adjacent upper sides serving as guide ramps 71. This not only simplifies the forming structure of the guide ramps 71 but also ensures the angular accuracy and stability of the guide ramps 71, guaranteeing the guiding effect on the PIN pins. Simultaneously, the feeding channel 20, the defective product unloading channel 30, and the good product unloading channel 40 are welded and fixed to the first crossbar 70, forming a stable integrated structure. The first crossbar 70 reliably fixes the structure inside the vibratory feeder 10, effectively preventing vibrations during operation of the vibratory feeder 10. This causes the positions of various components to shift, ensuring the accuracy of PIN needle feeding and screening. The good product discharge track 50 is fixed inside the vibratory feeder 10 by multiple second crossbars 80 welded to its lower end, which enhances the installation stability of the good product discharge track 50 and prevents it from shaking or shifting during PIN needle feeding, further ensuring the continuity and reliability of the feeding. In addition, this method of fixing by welding crossbars simplifies the installation structure of each component inside the vibratory feeder 10, making it easier to assemble and maintain, and improving the overall structural strength and service life of the device.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
