[0002] In industries such as electronic components, semiconductor packaging, and precision manufacturing, the quality and consistency of lead wires are crucial to overall product performance and reliability. Traditionally, the screening and identification of these leads relies primarily on manual visual inspection or simple mechanical devices.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0054] A lead screening and identification unit, comprising an identification mechanism 3, a correction mechanism 4 and a feeding mechanism 5;

[0055] The identification mechanism 3 includes a first identification component 31 and a second identification component 32;

[0056] The correction mechanism 4 includes a placement component 41 and a correction component 42;

[0057] There are two groups of placement components 41, which are arranged facing each other and form a placement space for the lead to be identified.

[0058] The first recognition component 31 is located in front of the placement space, and is used to recognize and determine whether the placement position of the current lead to be recognized is the target placement position;

[0059] The second identification component 32 is located above the placement space, and the second identification component 32 is used to identify the model of the lead to be identified;

[0060] The correction component 42 is located at the rear of the placement space, and the correction component 42 corrects and adjusts the lead wire after identification according to the information fed back by the first identification component 31 and the second identification component 32;

[0061] The feeding mechanism 5 is located below the placement space, and is used to transport the lead wires corrected by the correction component 42 to subsequent processing units.

[0062] like Figure 1As shown, the correction mechanism 4 comprises a placement component 41 and a correction component 42. The placement component 41 provides space for the lead to be processed, facilitating subsequent identification and processing by the recognition mechanism 3 and correction by the correction component 42. The recognition mechanism 3 then comprises a first recognition component 31 and a second recognition component 32, which work together to improve the efficiency and accuracy of lead processing. Specifically, the second recognition component 32 is located above the correction mechanism 4 and uses image recognition technology to determine the lead model, providing accurate information for subsequent processing by the first recognition component 31. The first recognition component 31 is located in front of the correction mechanism 4. Based on the model information provided by the second recognition component 32, it quickly captures the lead position and, using an image processing algorithm, identifies and determines whether the current placement position of the lead to be identified is the target placement position. If it deviates from the target placement position, a signal is sent to the correction component 42 for adjustment. Finally, the feeding mechanism 5 is responsible for accurately delivering qualified or unqualified leads, which have been corrected by the correction mechanism 4, to subsequent welding or other processing units.

[0063] In summary, the utility model comprises a collaborative workflow of the identification mechanism 3, the correction mechanism 4 and the feeding mechanism 5, and the entire screening and identification process is fully automated, which can efficiently process a large number of leads without manual intervention, ensuring their quality and consistency, greatly improving production efficiency and accuracy, thereby improving overall production efficiency and product quality.

[0064] To further illustrate, the first recognition component 31 includes a first recognition camera 311 , a first recognition base 312 , a first mounting plate 313 , a first transmission screw 314 , a first mounting base 315 , a first moving motor 316 and a viewfinder 317 ;

[0065] The first mounting plate 313 is mounted above the first identification base 312, the first mounting seat 315 is mounted on one end of the first mounting plate 313, the first transmission screw 314 is mounted along the length direction of the first mounting plate 313, and first limiting blocks 318 are mounted on both sides of the first transmission screw 314. A first sliding block 319 is slidably mounted on the rod of the first transmission screw 314, and both sides of the first sliding block 319 are slidably mounted with the first limiting blocks 318 respectively. One end of the first transmission screw 314 passes through the first mounting seat 315 and is mounted with a first identification driven wheel 3110;

[0066] A first sliding plate 3111 is installed on the upper surface of the first sliding block 319 , and the viewfinder 317 and the first recognition camera 311 are installed on the first sliding plate 3111 . The viewfinder 317 is located in front of the first recognition camera 311 .

[0067] The first mobile motor 316 is installed on the first mounting seat 315, and the motor shaft of the first mobile motor 316 passes through the first mounting seat 315 and is installed with an identification first driving wheel 3112. The outer wheel surface of the identification first driving wheel 3112 and the outer wheel surface of the identification first driven wheel 3110 are provided with a first transmission belt 3113.

[0068] Specifically, such as Figure 2 As shown, the first recognition component 31 includes a viewfinder 317, an auxiliary tool for observing photo composition, and an adjustable mechanical transmission structure to ensure that the camera can accurately align and capture the lead position. When the first movable motor 316 is activated, the motor shaft of the first movable motor 316 drives the first recognition driving wheel 3112 to rotate, which in turn drives the first transmission belt 3113 to circulate along the outer surfaces of the first recognition driving wheel 3112 and the first recognition driven wheel 3110. The first transmission screw 314 connected to the first recognition driven wheel 3110 also rotates accordingly. The first sliding block 319 on the first transmission screw 314 drives the viewfinder 317 and the first recognition camera 311 to slide along the first transmission screw 314, enabling fine-tuning of the shooting position. This helps users preview the range and composition of the photo, allowing users to better control the image. It also reduces recognition errors caused by improper positioning of the first recognition camera 311, thereby improving recognition accuracy.

[0069] To further illustrate, the second recognition component 32 includes a second recognition camera 321 , a second mounting plate 322 , a second guide rod 323 , a second sliding block 324 , a third sliding block 325 , a second fixing plate 326 and a third fixing plate 327 ;

[0070] Two second guide rods 323 are arranged side by side on the upper surface of the second mounting plate 322. The second sliding block 324 and the third sliding block 325 are slidably mounted on the two second guide rods 323. The second sliding block 324 is located above the third sliding block 325.

[0071] One end of the second fixing plate 326 is fixedly mounted to the second sliding block 324 , and the other end of the second fixing plate 326 is mounted with the second recognition camera 321 ;

[0072] The middle portion of the third fixing plate 327 is fixedly mounted to the third sliding block 325 , and lighting lamps 328 are mounted on both ends of the third fixing plate 327 .

The second and third sliding blocks 324 and 325 slide on the second guide rod 323, respectively driving the second fixing plate 326, on which the second recognition camera 321 is mounted, and the third fixing plate 327, on which the lighting fixture 328 is mounted, to move to accommodate wires of varying sizes. Furthermore, the lighting fixtures 328 are located on either side of the second recognition camera 321, providing uniform illumination and enhancing the stability and accuracy of image recognition.

[0074] To further illustrate, the placement assembly 41 includes a placement base 411 , a placement motor 412 , a placement plate 413 and at least two receiving columns 414 ;

[0075] One end of the motor shaft of the placing motor 412 away from the placing motor 412 is fixedly installed on the upper end of the placing base 411, and the motor shaft of the placing motor 412 is fixedly connected to one plate surface of the placing plate 413. The placing plate 413 is provided with a correction adjustment strip hole 4130 along its length direction, and one end of the two receiving columns 414 is detachably installed on the correction adjustment strip hole 4130 on the placing plate 413, and the other end of the two receiving columns 414 is provided with a placing arc groove 415. The distance between the two receiving columns 414 in the length direction of the placing plate 413 forms a placement length space for placing the lead.

[0076] Specifically, such as Figure 3 As shown, first, placement motor 412 drives placement plate 413 via its motor shaft, enabling fine-tuning of the position between the two sets of placement assemblies 41 to accommodate leads of varying widths. Second, the position of receiving posts 414 within the corrective adjustment slots 4130 is adjustable to accommodate leads of varying lengths and ensure stable placement. The design of placement assembly 41 enhances adaptability and flexibility in lead placement, enabling it to handle leads of varying sizes.

[0077] To further illustrate, the number of the receiving columns 414 is three groups, one of which is fixedly mounted on one end of the placement plate 413, and the other two receiving columns 414 are detachably mounted on the correction adjustment strip holes 4130 on the placement plate 413. Figure 3 As shown, the fixed support posts 414 serve as reference points to ensure stability during placement. The other two sets of adjustable support posts 414 are precisely adjusted via the adjustment bars 4130 based on the actual lead length and requirements, achieving a wider placement range and higher efficiency.

[0078] To further illustrate, the correction assembly 42 includes a correction base 421 , a correction moving motor 422 , a correction rotating motor 423 , and a correction clamping motor 424 ;

[0079] The corrective movable motor 422 is installed on the upper end of the corrective base 421, and the side of the corrective movable motor 422 is protruding along the direction of extension and contraction of the motor shaft of the corrective movable motor 422 and is provided with a corrective guide block 425.

The outer wheel surface of the correction driving wheel 428 and the outer wheel surface of the correction driven wheel 4210 are provided with a correction transmission belt 4211. Two correction clamps 4212 are installed on the motor shaft of the correction clamping motor 424. The correction clamping motor 424 is used to control the two correction clamps 4212 to move away from or closer to each other, and the approach of the two correction clamps 4212 is used to clamp the lead to be identified placed on the placement space.

[0080] Specifically, such as Figure 3 As shown, the correction movement motor 422 is connected to the correction movement slide 426 via the correction guide block 425 to achieve horizontal movement. The correction connection plate 427 is installed on the slide, on which the correction rotation motor 423 and the correction clamping motor 424 are installed. The motor shaft of the correction rotation motor 423 and the correction clamping motor 424 are connected to the correction driving pulley 428 and the correction driven pulley 4210 via the correction transmission belt 4211. The correction rotation motor 423 is used to achieve rotational adjustment of the correction clamping fixture 4212 on the correction clamping motor 424. Furthermore, the correction clamping motor 424 is used to control the opening and closing of the correction clamping fixture 4212, accurately clamping the lead wire for correction.

[0081] To further illustrate, the correction mechanism 4 also includes a correction limit assembly 43;

[0082] The correction limit assembly 43 includes a rotation limit block 431 and a rotation limit member 432. The rotation limit block 431 is provided on the correction connection plate 427 and is located between the correction rotation motor 423 and the correction clamping motor 424. A limiting groove 433 is defined on the rotation limit block 431. The rotation limit member 432 is fixedly mounted on the correction clamping motor 424.

[0083] When the correction rotation motor 423 drives the correction clamping motor 424 to rotate, the rotation limiting member 432 on the correction clamping motor 424 can movably penetrate the limiting groove 433 .

[0084] Specifically, such as Figure 4-5 As shown, the cooperation between the rotation limiter 432 and the limit groove 433 limits the rotation range of the correction clamping motor 424 through physical contact, thereby preventing excessive rotation from causing damage to the device or damage to the lead.

The vertical feed assembly utilizes a vertical feed motor 54 mounted on the horizontal feed slide block 53, coupled with a feed slide 57 and a feed guide block 56 driven by the motor shaft, enabling flexible vertical adjustment. The feed clamping assembly, mounted on a feed connection plate 59 on the feed slide 57, is driven by a feed clamping motor 55, driving two feed clamps 58 to stably clamp and release the corrected lead wire, ensuring lead stability during the feeding process.

At least two sets of the feed clamping members 583 are detachably mounted on the feed adjustment bar hole 5820. The distance between the two sets of the feed clamping members 583 along the length of the feed extension plate 582 forms a feed clamping length space for clamping the lead wire.

[0094] A feeding arc groove 584 is provided at one end of the feeding clamping member 583 away from the feeding extension plate 582; when the feeding clamping motor 55 drives a pair of the feeding extension plates 582 to approach each other, the two feeding arc grooves 584 close together to form a feeding clamping width space for clamping the outer surface of the lead.

[0095] Specifically, the feed clamp 58 utilizes a design that combines articulation and adjustment, comprising a feed hinge 581, a feed extension plate 582, and an adjustable feed clamp 583. The feed hinge 581 is connected to the feed clamp motor 55 via dual hinge points, ensuring flexible clamping. Feed adjustment slots 5820 on the feed extension plate 582 allow the user to install multiple sets of feed clamps 583 according to lead size, creating an adjustable feed clamping length. The arc-shaped feed groove 584 at the end of the feed clamp 583 creates a feed clamping width that adapts to the lead shape during clamping, further ensuring stable and reliable clamping.

[0096] To further explain, there are four feed clamps 583 , one of which is fixedly mounted on one end of the feed extension plate 582 , and the other three feed clamps 583 are detachably mounted on the feed adjustment bar holes 5820 on the feed extension plate 582 .

[0097] Specifically, the fixed feed clamp 583 serves as a reference point to ensure stability during placement. The other three sets of adjustable feed clamps 583 are precisely adjusted via feed adjustment slots 5820 based on the actual lead length and requirements, achieving a wider placement range and higher efficiency.
