[0002] In the field of electronic component manufacturing, pins are widely used in various connectors, electronic packaging, and circuit board assembly processes. S-bend pins, due to their unique geometry, offer significant advantages in improving solder joint strength, enhancing mechanical connection performance, and adapting to diverse circuit layouts. However, S-bend pins present numerous challenges during the loading process, impacting automated production efficiency and product consistency. Therefore, maintaining the quality of the pins during loading is crucial to avoid impacting subsequent processing.

[0003] After searching, a Chinese patent (publication number: CN212531106U) discloses a PIN needle feeding device, which includes a body frame and a vibration feeding device. The vibration feeding device is arranged on the body frame and also includes a material placement piece and a pushing assembly; the pushing assembly is provided with a pushing plate and a pushing power device, the pushing plate and the discharge port of the vibration feeding device are arranged to slide relative to each other, the pushing power device is used to drive the pushing plate and the discharge port of the vibration feeding device to move relative to each other, the pushing plate is provided with a pushing hole position for receiving the PIN needle from the discharge port of the vibration feeding device; the material placement piece is provided with a material placement hole position; and it also includes a mechanical material picking device for moving the PIN needle from the pushing hole position to the material placement hole position.

[0004] In the prior art, due to the unstable arrangement of PIN needles, poor consistency is likely to occur during loading, and the PIN needles may be slightly bent or have length deviations during loading, which can easily affect subsequent processing links and affect the quality of the final product. Therefore, the present invention proposes an automatic loading device for S-bend PIN needles. Summary of the Invention

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

[0006] The present invention can be implemented by the following technical solution: an S-bend PIN needle automatic feeding device includes a base, a vibration disk assembly and a fixing frame are installed on the upper side of the base, and a transfer assembly is installed on the upper side of the base between the vibration disk assembly and the fixing frame;

[0007] A circulating conveying assembly is installed inside the fixing frame, and a winding assembly is installed on one side of the fixing frame on the upper side of the base. A feed belt moving along the circulating conveying assembly is wound inside the winding assembly, and a plurality of PIN needle raw material fixing areas are equidistantly arranged on the upper side of the feed belt;

[0008] The discharge port of the vibration plate assembly is equipped with a feeding assembly, which 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;

[0009] 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.

[0010] The transfer assembly moves each PIN along the notch of the feed trough to the corresponding PIN raw material fixing area on the feed belt;

[0011] The fixed frame is sequentially installed with a flatness detection component, an image recognition component and a correction component on the outer side along the moving direction of the circulating conveying component;

[0012] Among them, the flatness detection component is located on the upper side of the feed belt where the PIN needle raw material is not installed, and the image recognition component and the correction component are installed on the upper side of the feed belt where the PIN needle raw material is installed;

[0013] The flatness detection component contacts the feeder belt as it moves and generates a corresponding detection signal based on the flatness of the feeder belt. By converting and monitoring the detection signal, the staff can monitor the flatness of the feeder belt to avoid problems with the flatness of the feeder belt that may affect the subsequent loading of PIN needle raw materials;

[0014] When the feed belt carries the PIN needle raw 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;

[0015] The image recognition component first identifies the integrity of the PIN material. By comparing the lengths of both ends of the PIN material with a preset material length threshold, it determines whether the PIN material is bent or has length deviations caused by other factors. After the image recognition component successfully identifies the length of the PIN material, it then identifies whether the position data between the first identification boundary and the second identification boundary conforms to the preset position data. If so, the position deviation between the PIN material and the second identification boundary is calculated to determine adjustment data, and the image recognition component transmits the adjustment data to the correction component.

[0016] 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.

[0017] A further technical improvement of the present invention is that: the feed belt includes a belt body, and a plurality of unit fixing members are installed on the upper side of the belt body as a PIN needle raw material fixing area;

[0018] A groove is provided inside the unit fixing part, and the end of the groove facing away from the vibration plate assembly is a closed structure, which is used to support the PIN needle material and limit it;

[0019] A communication port is provided on the lower side of the unit fixing slot to facilitate the correction component to contact the PIN needle material and move it;

[0020] At the same time, recessed openings are provided on both sides of the unit fixing member along the moving direction of the circulating conveying component to facilitate the flatness detection component to extend into the unit fixing member, thereby improving the monitoring accuracy.

[0021] A further technical improvement of the present invention is that: the unit fixing member is provided with side blocks on the side of a group of recessed openings, an arched sliding member is slidably connected between the two groups of side blocks via an elastic member, and the sliding direction of the arched sliding member is perpendicular to the groove body of the unit fixing member;

[0022] At the same time, the arched sliding member includes an arched segment, and both sides of the arched segment are provided with connecting segments connected to the side blocks in the corresponding directions;

[0023] The two groups of connecting sections are embedded into the corresponding recessed openings on one side of the unit fixing member groove body to fix the PIN needle raw material.

[0024] A further technical improvement of the present invention is that: the correction assembly includes a suspension and a support frame;

[0025] The suspension is installed on the outside of the circulating conveying assembly, and the top of the suspension extends to the upper side of the moving path of the feed belt, and a first horizontal driving structure is installed on the top of the suspension. The output end of the first horizontal driving structure is installed with a first lifting assembly, and the output end of the first lifting assembly moves downward to contact the PIN needle raw material from the upper side thereof;

[0026] The support frame is installed inside the circulating conveyor assembly and is arranged on the lower side of the moving path of the feed belt. A second horizontal driving structure is installed on the top of the support frame. A second lifting assembly is installed at the output end of the second horizontal driving structure. The output end of the second lifting assembly moves upward to pass through the communication port at the bottom of the unit fixing member and contact the PIN needle raw material;

[0027] The output ends of the first lifting assembly and the second lifting assembly are arranged along the same axial direction. Based on the preset moving path and height of the unit fixing member and the PIN needle raw material, the PIN needle raw material is synchronously contacted, and the position of the PIN needle raw material in the groove of the unit fixing member is corrected through the synchronous movement of the first horizontal driving structure and the second horizontal driving structure.

[0028] A further technical improvement of the present invention is that: at least one set of third horizontal drive structures is installed on the upper side of the support frame on one side of the second horizontal drive structure, and the moving direction of the output end of the third horizontal drive structure is perpendicular to the moving direction of the output end of the second horizontal drive structure;

[0029] A connecting piece is installed at the output end of the third horizontal driving structure, and a third lifting assembly is installed on the upper side of the connecting piece;

[0030] After being started, the output end of the third lifting assembly moves upward to the inside of the arched section of the arched sliding member, and cooperates with the third horizontal driving structure to move the arched sliding member along the side block portion through the compression sliding member.

[0031] A further technical improvement of the present invention is that: the flatness detection assembly includes a first connecting frame, the first connecting frame is arranged on one side of the circulating conveying assembly, and an angle sensing unit is installed inside the first connecting frame, and a circular rotating member is rotatably connected to the lower side of the angle sensing unit inside the first connecting frame;

[0032] The angle sensing unit is provided with an identification area on the side facing the rotating member, for identifying the rotation angle of the rotating member, and the arc of the identification area matches the rotating member, and the rotation angle information of the rotating member is converted into corresponding information data, and the integrity of the feed belt is monitored by monitoring the fluctuation of the information data;

[0033] A connecting rod is installed on one side of the rotating part, and the end of the connecting rod facing away from the first connecting frame is rotatably connected to a contact wheel. The contact wheel extends into the moving path of the feed belt and passes through the recessed openings of each unit fixing member when the feed belt moves.

[0034] A further technical improvement of the present invention is that: the circulating conveying assembly includes driving wheels located at both ends of the fixed frame, and the outer sides of the two sets of driving wheels are provided with driving belts;

[0035] A magnetic attraction area is provided on the outer side of the driving belt;

[0036] The lower side of the belt body is provided with a plurality of magnetic attraction parts whose intervals match the intervals of the respective unit fixing members;

[0037] When the feeding belt moves along the circulating conveying assembly in the fixed frame, the belt body in the feeding belt contacts the synchronous belt, and the magnetic attraction portion on the lower side of the belt body is magnetically attracted to the magnetic attraction area of the driving belt.

[0038] A further technical improvement of the present invention is that: a flattening assembly is installed on the outside of the base located on the fixed frame, and the flattening assembly is arranged on the side of the flatness detection assembly facing away from the moving direction of the circulating conveying assembly;

[0039] The flattening assembly includes a second connecting frame, the top of which extends to the upper side of the moving path of the feeding belt, and a connecting block is installed on the top of the second connecting frame;

[0040] The connecting block is rotatably connected to the contact piece via an elastic reset piece along the moving direction of the feeding belt;

[0041] The bottom of the contact piece extends into the moving path of the feeding belt for contacting with each unit fixing piece.

[0042] Compared with the prior art, the present invention has the following beneficial effects:

[0043] The present invention monitors the flatness of the feed belt by using a flatness detection component before assembling the PIN pin raw material and the feed belt, thereby avoiding the problem of affecting the feeding quality of the PIN pin raw material due to deformation of the feed belt, and also avoiding the subsequent PIN pin raw material blocking the unit fixing part, which makes it difficult to distinguish whether it is the unit fixing part or the PIN pin raw material when a problem occurs.

[0044] Furthermore, after the PIN pin raw material and the unit fixing part are assembled, the present invention can monitor the assembly quality of the PIN pin raw material and the unit fixing part through the image recognition component and the correction component. The present invention can also perform subsequent position correction operations based on the integrity recognition and position deviation recognition of the PIN pin raw material by the image recognition component, thereby improving the overall loading efficiency and quality of the device.

[0045] On the other hand, when the position of the PIN needle material is corrected, the present invention can avoid damage to the PIN needle material by adjusting the contact position between the unit fixing member and the PIN needle material. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0058] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0059] Example 1

[0060] See also Figure 1-5As shown, the present invention provides an S-bend PIN automatic feeding device, comprising a base 1, a vibration disk assembly 2 and a fixing frame 4 are installed on the upper side of the base 1, and a transfer assembly 6 is installed on the upper side of the base 1 between the vibration disk assembly 2 and the fixing frame 4;

[0061] A circulating conveying assembly 5 is installed inside the fixing frame 4. A winding assembly 7 is installed on the upper side of the base 1 on one side of the fixing frame 4. A feeding belt 8 that moves along the circulating conveying assembly 5 is wound inside the winding assembly 7. A plurality of PIN needle raw material fixing areas are equidistantly arranged on the upper side of the feeding belt 8.

[0062] The discharge port of the vibration plate assembly 2 is equipped with a feeding assembly 3, which extends to one side of the fixed frame 4. The feeding assembly 3 is arranged perpendicular to the moving direction of the circulating conveying assembly 5, and the transfer assembly 6 is arranged on one side of the feeding assembly 3;

[0063] A feeding trough is provided inside the feeding assembly 3. When feeding, the PIN needle raw materials are moved along the feeding trough to one side of the fixing frame 4 in sequence. A notch is provided on the upper side of one end of the feeding trough facing the fixing frame 4.

[0064] The transfer assembly 6 moves each PIN needle along the notch of the feed trough in sequence to the corresponding PIN needle raw material fixing area on the feed belt 8;

[0065] The fixed frame 4 is provided with a flatness detection component 11, an image recognition component 9 and a correction component 10 in sequence on the outer side of the circulating conveying component 5 along the moving direction;

[0066] Among them, the flatness detection component 11 is located on the upper side of the area where the PIN needle raw material is not installed on the feeding belt 8, and the image recognition component 9 and the correction component 10 are installed on the upper side of the area where the PIN needle raw material is installed on the feeding belt 8;

[0067] The flatness detection component 11 contacts the feeder belt 8 when the feeder belt 8 moves, and generates a corresponding detection signal based on the flatness of the feeder belt 8. The staff can monitor the flatness of the feeder belt 8 by converting and monitoring the detection signal, thereby avoiding problems with the flatness of the feeder belt 8 that may affect the subsequent loading of PIN needle raw materials;

[0068] When the feed 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 feed belt 8 and establishes a second recognition boundary based on the edge of the unit fixing member 82;

[0069] The image recognition component 9 first identifies the integrity of the PIN material. By comparing the lengths of both ends of the PIN material with a preset material length threshold, it determines whether the PIN material is bent or has length deviations caused by other factors. After the image recognition component 9 has successfully identified the length of the PIN material, it then identifies whether the position data between the first identification boundary and the second identification boundary conforms to the preset position data. If so, the position deviation between the PIN material and the second identification boundary is calculated to determine adjustment data, and the image recognition component 9 transmits the adjustment data to the correction component 10.

[0070] When the PIN needle material that needs to be adjusted passes by, the correction component 10 adjusts the position of the corresponding PIN needle material in the feeding belt 8 based on the adjustment data when the transfer component 6 moves the PIN needle material to load the material;

[0071] In this embodiment, the base 1 is provided with a second set of transfer components 6 on one side of the fixing frame 4 located in the direction of movement of the correction component 10 toward the circulating conveying component 5, for removing the PIN needle raw materials identified as problematic by the image recognition component 9 from the feeding belt 8;

[0072] 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;

[0073] 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;

[0074] In addition, a communication port is provided on the lower side of the unit fixing member 82, which is used to facilitate the correction component 10 to contact the PIN needle material and move it;

[0075] 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.

[0076] The calibration assembly 10 includes a suspension 101 and a support frame 102;

[0077] The suspension 101 is mounted on the outside of the circulating conveyor assembly 5, and the top of the suspension 101 extends to the upper side of the moving path of the feed belt 8. A first horizontal driving structure 103 is mounted on the top of the suspension 101, and a first lifting assembly 104 is mounted on 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.

[0078] The support frame 102 is installed inside the circulating conveyor assembly 5 and is arranged on the lower side of the moving path of the feed belt 8. A second horizontal driving structure 105 is installed on the top of the support frame 102. 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 pass through the communication port at the bottom of the unit fixing member 82 to contact the PIN needle raw material;

[0079] The output ends of the first lifting assembly 104 and the second lifting assembly 106 are arranged along the same axial direction. 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 the position of the PIN needle raw material in the groove of the unit fixing member 82 is corrected through the synchronous movement of the first horizontal driving structure 103 and the second horizontal driving structure 105.

[0080] The flatness detection assembly 11 includes a first connecting frame 111, which is arranged on one side of the circulating conveying assembly 5. An angle sensing unit 112 is installed inside the first connecting frame 111, and a circular rotating member 113 is rotatably connected to the lower side of the angle sensing unit 112 inside the first connecting frame 111.

[0081] The angle sensing unit 112 is provided with an identification area on one side facing the rotating member 113, for identifying the rotation angle of the rotating member 113. The arc 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 feed belt 8 is monitored.

[0082] A connecting rod 114 is installed on one side of the rotating part 113, and 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 feed belt 8 and passes through the recessed openings of each unit fixing part 82 when the feed belt 8 moves.

[0083] During loading, the winding assembly 7 cooperates with the circulating conveying assembly 5 to move the feed belt 8 along one side of the feed assembly 3. When the feed belt 8 moves, the contact wheel 115 in the flatness detection assembly 11 contacts each unit fixing part 82 in the feed belt 8. When in contact with the unit fixing part 82, if the contact wheel 115 shakes, the rotating part 113 is driven 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.

[0084] When the angle sensing unit 112 recognizes that the rotation frequency and amplitude are greater than the preset frequency threshold and amplitude threshold, the unit fixing part 82 at the corresponding position is marked. When loading the material subsequently, the transfer component 6 stops loading the unit fixing part 82. 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 the group of unit fixing parts 82 to determine whether the group of unit fixing parts 82 is damaged or has other problems. If it is determined that the unit fixing part 82 is damaged or has other problems, a warning message is issued;

[0085] At the same time, the vibrating plate assembly 2 moves the PIN needle raw materials along the feeding trough of the feeding assembly 3 to the notch of the feeding assembly 3 in sequence. At the same time, the transfer assembly 6 moves each PIN needle raw material from the feeding assembly 3 to the corresponding unit fixing part 82 in the feeding belt 8 in sequence, and loads a group of PIN needle raw materials each time. The winding assembly 7 cooperates with the circular conveying assembly 5 to move the unit fixing part 82 in the feeding belt 8 by one station and move the new unit fixing part 82 to one side of the feeding assembly 3.

[0086] Subsequently, when the unit fixing part 82 carries the PIN needle raw material through the image recognition component 9, the image recognition component 9 identifies 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 correction component 10, and when the transfer component 6 assembles a new set of PIN needle raw materials with the unit fixing part 82, the correction component 10 is started, and the PIN needle raw material is contacted and fixed by the first lifting component 104 and the second lifting component 106. Then, the first horizontal drive structure 103 and the second horizontal drive structure 105 are started synchronously to translate the PIN needle raw material.

[0087] In this embodiment, the recognition system, control method and information transmission method used by the flatness detection component 11, the image recognition component 9 and the correction component 10 can adopt any mature solution in the existing technology to reduce production costs.

An arched sliding member 83 is slidably connected between the two groups of side blocks via elastic members, and the sliding direction of the arched sliding member 83 is perpendicular to the groove body of the unit fixing member 82;

[0101] At the same time, the arched sliding member 83 includes an arched segment, and both sides of the arched segment are provided with connecting segments connected to the side blocks in the corresponding directions;
