[0001] The present invention relates to the technical field of PIN pin processing, and specifically relates to an automatic feeding device for S-shaped PIN pins. Background Technique

[0002] In the field of electronic component manufacturing, PIN pins are widely used in various connectors, electronic packaging, and circuit board assembly processes. Among them, S-shaped PIN pins have significant advantages in improving welding strength, enhancing mechanical connection performance, and adapting to different circuit layouts due to their special geometric shape. However, there are many challenges in the feeding process of S-shaped PIN pins, which affect the automation production efficiency and product consistency. Therefore, when feeding PIN pins, it is necessary to maintain the feeding quality of PIN pins to avoid affecting subsequent processing.

[0003] After retrieval, the Chinese patent (Publication No.: CN212531106U) discloses a PIN pin feeding device, which includes a machine body frame and a vibrating feeding device. The vibrating feeding device is arranged on the machine body frame, and further includes a material placing member and a pushing component; the pushing component is provided with a pushing plate and a pushing power device. The pushing plate is slidably arranged opposite to the discharge port of the vibrating feeding device. The pushing power device is used to drive the pushing plate to perform relative translation with the discharge port of the vibrating feeding device. The pushing plate is provided with a pushing hole position for receiving PIN pins from the discharge port of the vibrating feeding device; the material placing member is provided with a material placing hole position; and further includes a mechanical picking device for moving the PIN pins from the pushing hole position to the material placing hole position.

[0004] In the prior art, due to the unstable arrangement of PIN pins, problems with poor consistency are likely to occur during feeding. Moreover, when feeding PIN pins, problems such as slight bending or length deviation may occur, which easily affect subsequent processing steps and the quality of the final product. Therefore, the present invention proposes an automatic feeding device for S-shaped PIN pins. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic feeding device for S-shaped PIN pins to solve the problems mentioned in the above background technique.

[0006] The present invention can be realized through the following technical solutions: An automatic feeding device for S-shaped PIN pins includes a base. A vibrating disk assembly and a fixing frame are adjacently arranged on the upper side of the base, and a transfer assembly is installed between the vibrating disk assembly and the fixing frame on the upper side of the base. A circulating conveying assembly is installed inside the fixing frame. A winding assembly is installed on one side of the fixing frame on the upper side of the base. A feeding belt that moves along the circulating conveying assembly is wound inside the winding assembly. A plurality of PIN pin raw material fixing areas are equidistantly arranged on the upper side of the feeding belt. The discharge port of the vibration plate assembly is equipped with a feeding assembly, the feeding assembly extends to one side of the fixed frame, and the feeding assembly is arranged perpendicular to the moving direction of the circulating conveying assembly, and the transfer assembly is arranged on one side of the feeding assembly; A feeding trough is provided inside the feeding assembly. When feeding, the PIN needle raw materials move along the feeding trough to one side of the fixed frame in sequence, and a notch is provided on the upper side of one end of the feeding trough facing the fixed frame.

The staff can monitor the flatness of the feeder belt by converting and monitoring the detection signal to avoid problems with the flatness of the feeder belt that affect the subsequent loading of PIN needle raw materials; When the feed belt carries the PIN needle material, the image recognition component establishes a first recognition boundary based on the edge of the belt body in the feed belt, and establishes a second recognition boundary based on the edge of the unit fixing part; The image recognition component first identifies the integrity of the PIN needle material, and compares the length of both ends of the PIN needle material with the preset material length threshold to determine whether the PIN needle material is bent or other factors cause the length deviation. After the image recognition component recognizes the length of the PIN needle material, it then identifies whether the position data between the first recognition boundary and the second recognition boundary conforms to the preset position data. If so, the position deviation between the PIN needle material and the second recognition boundary is calculated to obtain adjustment data, and the image recognition component transmits the adjustment data to the correction component. When the PIN needle material that needs to be adjusted passes by, the correction component adjusts the corresponding PIN needle material position in the feeding belt based on the adjustment data when the transfer component moves the PIN needle material to load.

[0018] Embodiment 1

[0019] Please refer to Figures 1-5 As shown in the figure, the present invention provides an S-shaped PIN needle automatic feeding device, including a base 1. A vibrating disk assembly 2 and a fixing frame 4 are adjacently installed on the upper side of the base 1, and a transfer assembly 6 is installed between the vibrating disk assembly 2 and the fixing frame 4 on the upper side of the base 1; A circulating conveying assembly 5 is installed inside the fixing frame 4, and a winding assembly 7 is installed on one side of the fixing frame 4 on the upper side of the base 1. A feeding belt 8 that moves along the circulating conveying assembly 5 is wound inside the winding assembly 7, and a plurality of PIN needle raw material fixing areas are equidistantly arranged on the upper side of the feeding belt 8; A feeding assembly 3 is installed at the discharge port of the vibrating disk assembly 2. The feeding assembly 3 extends to one side of the fixing frame 4, and the feeding assembly 3 is perpendicular to the moving direction of the circulating conveying assembly 5. The transfer assembly 6 is arranged on one side of the feeding assembly 3; A feeding groove is formed inside the feeding assembly 3. When feeding, the PIN needle raw materials move along the feeding groove to one side of the fixing frame 4 in sequence, and an opening is formed on the upper side of the feeding assembly 3 at the end of the feeding groove facing the fixing frame 4; The transfer assembly 6 moves each PIN needle along the opening of the feeding groove to the corresponding PIN needle raw material fixing area on the feeding belt 8 in sequence; A flatness detection assembly 11, an image recognition assembly 9 and a correction assembly 10 are sequentially installed on the outer side of the fixing frame 4 along the moving direction of the circulating conveying assembly 5; Among them, the flatness detection component 11 is located on the upper side of the area of ​​the feed belt 8 where the PIN needle raw material is not installed, and the image recognition component 9 and the correction component 10 are installed on the upper side of the area of ​​the feed belt 8 where the PIN needle raw material is installed; When the feed belt 8 moves, the flatness detection component 11 contacts the feed belt 8 and generates a corresponding detection signal based on the flatness of the feed belt 8. The staff can monitor the flatness of the feed belt 8 by converting and monitoring the detection signal, so as to avoid the problem of the flatness of the feed belt 8, which may affect the subsequent feeding of the PIN needle raw materials; When the feeding belt 8 carries the PIN needle material, the image recognition component 9 establishes a first recognition boundary based on the edge of the belt body 81 in the feeding belt 8 and establishes a second recognition boundary based on the edge of the unit fixing member 82; The image recognition component 9 first identifies the integrity of the PIN needle material, and compares the length of both ends of the PIN needle material with the preset material length threshold to determine whether the PIN needle material is bent or other factors cause the length deviation. After the image recognition component 9 recognizes the length of the PIN needle material, it then identifies whether the position data between the first recognition boundary and the second recognition boundary conforms to the preset position data. If they conform, the position deviation between the PIN needle material and the second recognition boundary is calculated to obtain adjustment data, and the image recognition component 9 transmits the adjustment data to the correction component 10. When the PIN needle material that needs to be adjusted passes by, the correction component 10 adjusts the corresponding PIN needle material position in the feeding belt 8 based on the adjustment data when the transfer component 6 moves the PIN needle material to load; In this embodiment, the base 1 is provided with a second group of transfer components 6 on one side of the fixing frame 4 located in the moving direction of the correction component 10 toward the circulating conveying component 5, for taking out the PIN needle raw materials identified as problematic by the image recognition component 9 from the feeding belt 8; The feeding belt 8 includes a belt body 81, and a plurality of unit fixing members 82 are installed on the upper side of the belt body 81 as a PIN needle raw material fixing area; A groove is provided inside the unit fixing member 82, and one end of the groove facing away from the vibration plate assembly 2 is a closed structure for supporting the PIN needle material and limiting its position; A communication port is provided on the lower side of the groove of the unit fixing member 82 to facilitate the correction component 10 to contact the PIN needle material and move it; At the same time, recessed openings are provided on both sides of the unit fixing member 82 along the moving direction of the circulating conveying component 5 to facilitate the flatness detection component 11 to extend into the unit fixing member 82 and improve the monitoring accuracy.

[0020] The correction assembly 10 includes a suspension 101 and a support frame 102; The suspension 101 is installed outside the circulating conveying assembly 5, and the top of the suspension 101 extends to the upper side of the moving path of the feeding belt 8. A first horizontal driving structure 103 is installed at the top of the suspension 101, and a first lifting assembly 104 is installed at the output end of the first horizontal driving structure 103. The output end of the first lifting assembly 104 moves downward to contact the PIN needle raw material from the upper side thereof. The support frame 102 is installed inside the circulating conveying assembly 5 and is arranged on the lower side of the moving path of the feeding belt 8. A second horizontal driving structure 105 is installed at the top of the support frame 102, and a second lifting assembly 106 is installed at the output end of the second horizontal driving structure 105. The output end of the second lifting assembly 106 moves upward to contact the PIN needle raw material through the communication port at the bottom of the unit fixing member 82. The output ends of the first lifting assembly 104 and the second lifting assembly 106 are arranged along the same axis. Based on the preset moving path and height of the unit fixing member 82 and the PIN needle raw material, the PIN needle raw material is synchronously contacted, and through the synchronous movement of the first horizontal driving structure 103 and the second horizontal driving structure 105, the position of the PIN needle raw material in the groove of the unit fixing member 82 is corrected.

[0021] The flatness detection assembly 11 includes a first connecting frame 111. The first connecting frame 111 is arranged on one side of the circulating conveying assembly 5, and an angle sensing unit 112 is installed inside the first connecting frame 111. A circular rotating member 113 is rotatably connected to the lower side of the angle sensing unit 112 inside the first connecting frame 111. An identification area is arranged on the side of the angle sensing unit 112 facing the rotating member 113 for identifying the rotation angle of the rotating member 113. The radian of the identification area matches that of the rotating member 113, and the rotation angle information of the rotating member 113 is converted into corresponding information data. By monitoring the fluctuation of the information data, the integrity of the feeding belt 8 is monitored. A connecting rod 114 is installed on one side of the rotating member 113. The end of the connecting rod 114 facing away from the first connecting frame 111 is rotatably connected to a contact wheel 115. The contact wheel 115 extends into the moving path of the feeding belt 8 and passes through the recesses of each unit fixing member 82 when the feeding belt 8 moves.

[0022] When feeding materials, the winding component 7 cooperates with the circulating conveying component 5 to move the feeding belt 8 along one side of the feeding component 3. When the feeding belt 8 is moving, the contact wheel 115 in the flatness detection component 11 contacts each unit fixing part 82 in the feeding belt 8. When contacting the unit fixing part 82, if the contact wheel 115 shakes, it drives the rotating part 113 to rotate through the connecting rod 114. The angle sensing unit 112 monitors each unit fixing part 82 by identifying the rotation frequency and amplitude of the rotating part 113; When the angle sensing unit 112 identifies that the rotation frequency and amplitude are greater than the preset frequency threshold and amplitude threshold, it marks the unit fixing part 82 at the corresponding position. During subsequent feeding, the transfer component 6 stops feeding the unit fixing part 82 at this position. And when the unit fixing part 82 moves to the lower side of the image recognition component 9, the image recognition component 9 performs image recognition on this group of unit fixing parts 82 to determine whether there are damages or other problems with this group of unit fixing parts 82. If it is determined that there are damages or other problems with the unit fixing part 82, a warning message is issued; At the same time, the vibrating disk component 2 moves the PIN needle raw materials along the feeding groove of the feeding component 3 to the notch part of the feeding component 3 in sequence. At the same time, the transfer component 6 moves each PIN needle raw material from the feeding component 3 to the corresponding unit fixing part 82 in the feeding belt 8 in sequence. And each time a group of PIN needle raw materials are fed, the winding component 7 cooperates with the circulating conveying component 5 to move a group of workstations for the unit fixing parts 82 in the feeding belt 8, and moves the new unit fixing part 82 to one side of the feeding component 3; Subsequently, when the unit fixing part 82 carries the PIN needle raw material through the image recognition component 9, the image recognition component 9 recognizes whether the PIN needle raw material is intact and whether it is correctly assembled with the unit fixing part 82. If the PIN needle raw material is intact but the assembly position is offset, the PIN needle raw material and the unit fixing part 82 pass through the calibration component 10. And when the transfer component 6 assembles a new group of PIN needle raw materials with the unit fixing part 82, the calibration component 10 is started. The PIN needle raw material is contact-fixed through the first lifting component 104 and the second lifting component 106. Subsequently, the first horizontal driving structure 103 and the second horizontal driving structure 105 are started synchronously to translate the PIN needle raw material.

[0023] And in this embodiment, the recognition systems, control methods, and information transmission methods used by the flatness detection component 11, the image recognition component 9, and the calibration component 10 can all adopt any mature solutions in the prior art to reduce production costs.
