Description

Technical Field

[0001] This invention relates to the field of surface mount technology, and in particular to an automatic orientation correction lead feeder for Hall effect sensor devices used in surface mount technology (SMT) processes and its operating method. Background Technology

[0002] Hall effect devices are solid-state magnetoelectric conversion electronic components that operate based on the Hall effect. They convert magnetic field signals into electrical signals and are widely used in industrial inspection, automotive electronics, and smart devices. Because Hall effect through-hole devices are small and essentially symmetrical, they require polarity during insertion. The polarity direction is confirmed by markings on the device itself. Currently, Hall effect through-hole devices are primarily manufactured by cutting the leads to the required length using a lead-cutting machine, and then manually identifying the device's polarity before inserting it into the hole of a special fixture for precise insertion into the PCB hole. Since they are through-hole devices, during insertion or placement, the nozzle clamps the device, preventing the bottom or side cameras of the placement machine from recognizing it.

[0003] Manual polarity verification is inefficient and prone to errors, and cannot guarantee 100% accuracy. If the polarity of a Hall effect sensor is reversed, it will not only pose a serious risk to the quality of subsequent products, but also require a large amount of manpower to find the cause of the fault.

[0004] Existing solutions all require manual intervention for orientation correction and lack online automatic polarity identification and orientation correction mechanisms, making it impossible to achieve a fully closed-loop material supply, resulting in low efficiency and the inability to achieve automatic placement. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic orientation correction lead-cutting feeder for Hall effect sensor components used in surface mount technology (SMT) processes, and its operating method, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical measures: an automatic orientation correction and lead-cutting feeder for Hall effect insertion devices used in surface mount technology (SMT) processes, characterized in that: it includes a cabinet for supporting the equipment, a vibratory feeder module is provided on the cabinet, a first linear vibratory feeding module is provided behind the vibratory feeder module, a first imaging station, a first flipping module, a second imaging station, a second flipping module and a lead-cutting station are sequentially provided behind the first linear vibratory feeding module, and a second linear vibratory feeding module is provided behind the lead-cutting station; The first linear vibrating feeding module includes a blocking device for blocking Hall devices. The blocking device includes an upper stop bar and a lower stop bar, wherein the upper stop bar blocks the element body of the Hall device and the lower stop bar blocks the pins of the Hall device. The first photo-taking station includes a first clamping cylinder assembly, which includes a cylinder chuck with a protruding clamping part integrally provided on the cylinder chuck. The first photo-taking station also includes a first CCD camera. The first flipping module includes a second clamping cylinder assembly and a flipping device that works in conjunction with the second clamping cylinder assembly and is located directly below it. The flipping device includes a rotary cylinder, an angle sensor is provided on the rotating rod of the rotary cylinder, and a gripper for gripping the Hall device is also provided on the rotating rod. The second cylinder clamping assembly includes a cylinder chuck. The second photo station includes the third clamping cylinder assembly; The second flipping module includes the fourth clamping cylinder assembly; The lead-cutting station includes a fifth cylinder clamping assembly, a sixth cylinder clamping assembly, and a seventh clamping assembly. A lead-cutting device for cutting off the paper tape of the Hall device is provided directly below the sixth cylinder clamping assembly. The second linear vibration feeding module includes a second vertical double rail, which includes an upper guide rail and a lower guide rail. The lower guide rail is used to block the lateral tilt of the Hall device, and the upper guide rail is used to press down on the upper end face of the element body of the Hall device.

[0007] Compared with the prior art, the advantages of this invention are: this novel structure does not require manual intervention for direction correction, can automatically identify polarity online, can ensure 100% correct polarity of Hall devices, and due to the use of automated operation, the quality consistency of finished products is better, which will not cause hidden dangers to product quality. It can realize automatic placement and improve production efficiency.

[0008] As an improvement of the present invention, the first clamping cylinder assembly, the second clamping cylinder assembly, the third clamping cylinder assembly, the fourth clamping cylinder assembly, the fifth clamping cylinder assembly, the sixth clamping cylinder assembly, and the seventh clamping cylinder assembly are mounted on the same main base plate, which is driven by a main drive cylinder through a main slider. The purpose of this design is that when the main drive cylinder is activated, the first, second, third, fourth, fifth, sixth, and seventh clamping cylinder assemblies form a complete clamping system (equivalent to seven workstations). Each clamping cylinder assembly reciprocates between two workstations, that is, it synchronously moves back and forth periodically along the same path between two workstations, so that the Hall effect device clamped on the clamping cylinder assembly is automatically clamped from the previous process to the next process.

[0009] As an improvement of the present invention, the shearing device includes an I-shaped cutter, a shearing seat that cooperates with the I-shaped cutter for shearing, and a shearing cylinder that drives the I-shaped cutter to perform the shearing action. The purpose of this design is that the cutter adopts an "I-shaped" shape, and this symmetrical shape ensures balanced force during shearing.

[0010] As an improvement to the present invention, the shearing device further includes a cutter limiting seat, wherein the I-shaped cutter and the cutter limiting seat are in clearance fit. The purpose of this design is that the clearance fit between the I-shaped cutter and the cutter limiting seat allows the cutter to remain in the same position, thereby improving shearing accuracy.

[0011] As an improvement of the present invention, a ring light source is provided in front of the first CCD camera. The purpose of this design is mainly to improve the illumination conditions of the object surface, ensure image clarity, and its core function is to provide uniform illumination, eliminate shadows, and improve the visibility of details.

[0012] As an improvement to the present invention, a paper tape sensor for detecting the presence or absence of paper tape in the Hall device is provided next to the seventh clamping assembly. The purpose of this design is to prevent Hall devices with residual paper tape that have not been completely cut from entering the next process.

[0013] As an improvement of the present invention, a material detection sensor is provided on the first linear vibrating feeding module. The purpose of this design is that the material detection sensor, through its through-beam structure, can detect whether there is a shortage of material. Once a shortage of material is detected, the alarm system sounds to remind the user to handle the situation on-site.

[0014] As an improvement of the present invention, a cylinder buffer rod is provided next to the main slider. The purpose of this design is that the cylinder buffer rod can slow down the movement speed of the main slider, thereby reducing collisions between mechanical parts and reducing noise and vibration.

[0015] This application also provides an operation method for an automatic orientation correction lead-cutting feeder for Hall effect devices used in surface mount technology (SMT) processes, characterized by the following working steps: 1. Vibratory feeder module feeding: Automatically arranges scattered Hall effect devices into a neat and oriented configuration, accurately conveying them to the next process; 2. The first linear vibrating feeding module feeds the material: it serves as a connector, transports the Hall effect device into position, and maintains it in a clampable state; 3. First imaging station detects polarity: Identifies side A of the Hall effect device; 4. The first flip module operates: it flips the Hall device 180 degrees; 5. Second imaging station detects polarity: Identifies the B-side of the Hall effect device; 6. Second flip module operation: Based on the above identification results, determine whether to perform the final flip channel flip, that is, based on the identification results of the previous step and the patch requirements, decide whether to flip again to ensure 100% omnidirectional output consistency; 7. Cutting station operation: Cuts off the paper tape and excess pin length from the Hall effect device; 8. The second inline vibrating feeder module is used for feeding: it serves as a connector and delivers the Hall effect device to the designated position, while maintaining the pick-and-place machine's ability to pick it up.

[0034] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0035] Please refer to Figure 1 -17.

[0036] This embodiment provides an automatic orientation correction feeder for Hall effect sensor components in a surface mount technology (SMT) process. It includes a cabinet 1 for supporting the equipment, on which a vibratory feeder module 2 is mounted on a base platform 43. The vibratory feeder module 2 includes a vibratory feeder body 44 with a pulse electromagnet underneath, which causes the hopper to vibrate vertically. An inclined spring plate drives the hopper to oscillate around its vertical axis. The Hall effect sensors 10 inside the hopper rise along a spiral track due to this vibration. During this ascent, the sensors undergo a series of track selections and attitude adjustments, automatically arranging the Hall effect sensors 10 into an orderly and oriented configuration, accurately conveying them to the next process step.

[0037] In the embodiments of this invention application, please refer to Figure 1 and Figure 11 The vibratory feeder module 2 is followed by a first linear vibratory feeding module 3. The first linear vibratory feeding module 3 is followed by a first photo-taking station 4, a first flipping module 5, a second photo-taking station 6, a second flipping module 7, and a foot-cutting station 8. The foot-cutting station 8 is followed by a second linear vibratory feeding module 9.

[0038] In the embodiments of this invention application, please refer to Figure 3 and Figure 16 The first linear vibrating feed module 3 includes a blocking device for blocking the Hall effect device 10. The blocking device includes an upper stop bar 11 and a lower stop bar 12. The upper stop bar 11 blocks the side of the lower half of the Hall effect device 10's component body 13, and the lower stop bar 12 blocks the pins 14 of the Hall effect device 10. This upper and lower blocking structure allows the Hall effect device 10 to be securely fixed in the clamping position. Simultaneously, the upper half of the Hall effect device 10's component body 13 can be exposed for clamping by the protruding clamping portion 17 of the cylinder chuck 16 of the first clamping cylinder assembly 15. The first linear vibrating feed module 3 includes a first vertical double rail 45, whose structure is the same as the second vertical double rail 30.

[0039] In the embodiments of this invention application, please refer to Figure 4 and Figure 14 The first photo-taking station 4 includes a first clamping cylinder assembly 15, which includes a cylinder chuck 16. The cylinder chuck 16 is integrally provided with a forward-protruding clamping part 17. The first photo-taking station 4 also includes a first CCD camera 18.

[0040] In an embodiment of this invention, the first flipping module 5 includes a second clamping cylinder assembly 19, please refer to... Figure 9 The second cylinder clamping assembly includes a cylinder chuck 16. Furthermore, the first tilting module 5 also includes a tilting device that works in conjunction with the second clamping cylinder assembly 19 and is located directly below it; please refer to [reference needed]. Figure 5The flipping device includes a rotary cylinder 20, an angle sensor 22 is provided on the rotating rod 21 of the rotary cylinder 20, and a gripper 23 for gripping the Hall device 10 is also provided on the rotating rod 21.

[0041] The second imaging station 6 includes a third clamping cylinder assembly 24, whose structure is the same as that of the first clamping cylinder assembly 15. Other components of the second imaging station 6, such as the second CCD camera 49, are the same as those of the first imaging station 4.

[0042] The second flipping module 7 includes a fourth clamping cylinder assembly 25, which has the same structure as the second clamping cylinder assembly 19. The other structures of the second flipping module 7 are the same as those of the first flipping module 5.

[0043] In the embodiments of this invention application, please refer to Figure 6 The lead-cutting station 8 includes a fifth cylinder clamping assembly, a sixth cylinder clamping assembly, and a seventh clamping assembly. A lead-cutting device for cutting off the paper tape 48 of the Hall device 10 is located directly below the sixth cylinder clamping assembly. Its function is to remove the leads and paper tape 48 from the Hall device 10. The lead-cutting station 8 also includes a paper tape waste bin 46.

[0044] Further, please refer to Figure 17 The shearing device includes an I-shaped cutter 36, a shearing seat 37 that cooperates with the I-shaped cutter 36 for shearing, and a shearing cylinder 38 that drives the I-shaped cutter 36 to perform the shearing action. The cutter adopts an "I-shaped" shape, and this symmetrical shape ensures balanced force during shearing.

[0045] Furthermore, the shearing device also includes a cutter limiting seat 39, with the I-shaped cutter 36 and the cutter limiting seat 39 in a clearance fit. This clearance fit between the I-shaped cutter 36 and the cutter limiting seat 39 allows the cutter to remain in the same position, improving cutting accuracy.

[0046] In the embodiments of this invention application, please refer to Figure 7 and Figure 8 The second vertical vibration feeding module 9 includes a second vertical double rail 30, which includes an upper guide rail 31 and a lower guide rail 32. The lower guide rail 32 is used to block the lateral tilt of the Hall device 10, and the upper guide rail 31 is used to press down on the upper end face of the element body 13 of the Hall device 10.

[0047] In the embodiments of this invention application, please refer to Figure 12 and Figure 13The first clamping cylinder assembly 15, the second clamping cylinder assembly 19, the third clamping cylinder assembly 24, the fourth clamping cylinder assembly 25, the fifth clamping cylinder assembly 26, the sixth clamping cylinder assembly 27, and the seventh clamping cylinder assembly 28 all include clamping cylinders 47 and are all uniformly mounted on the same main base plate 33, which is driven by the main drive cylinder 34 through the main slider 35. When the main drive cylinder 34 actuates, the first clamping cylinder assembly 15, the second clamping cylinder assembly 19, the third clamping cylinder assembly 24, the fourth clamping cylinder assembly 25, the fifth clamping cylinder assembly 26, and the seventh clamping cylinder assembly 28 form a complete clamping system (equivalent to seven workstations). Each clamping cylinder assembly reciprocates between two workstations, that is, it moves back and forth synchronously along the same path between two workstations, causing the Hall effect devices 10 clamped on the clamping cylinder assemblies to be synchronously clamped from the previous process to the next process. Each of the seven workstations clamps one Hall effect device, and they are processed step by step at each workstation in an alternating manner. In mass production, the main drive cylinder moves back and forth seven times, and the seven Hall effect devices can complete the processing of seven processes.

[0048] In the embodiments of this invention application, please refer to Figure 4 A ring light source 40 is positioned in front of the first CCD camera 18. The purpose of this design is primarily to improve the lighting conditions on the object's surface, ensure image sharpness, and its core function is to provide uniform illumination, eliminate shadows, and improve the visibility of details.

[0049] In the embodiments of this invention application, please refer to Figure 6 Next to the seventh clamping assembly, a paper tape sensor 29 is provided to detect whether the Hall device 10 has paper tape 48. This prevents the Hall device 10 with incompletely cut paper tape 48 from entering the next process and prevents jamming.

[0050] In the embodiments of this invention application, please refer to Figure 3 The first vertical vibrating feed module 3 is equipped with a material detection sensor 41. The material detection sensor 41, with its through-beam structure, can detect whether there is a shortage of material. Once a shortage of material is detected, the alarm system sounds to remind the user to handle the situation on-site.

[0051] In the embodiments of this invention application, please refer to Figure 13 A cylinder buffer rod 42 is provided next to the main slider 35. The cylinder buffer rod 42 can slow down the movement speed of the main slider 35, thereby reducing collisions between mechanical parts and reducing noise and vibration.

[0052] This application also provides an operation method for an automatic orientation correction lead-cutting feeder for Hall effect devices used in surface mount technology (SMT) processes, the working steps of which are as follows: 1. Vibratory Feeder Module 2: Automatically arranges scattered Hall effect devices 10 into a neat and oriented arrangement, accurately conveying them to the next process. The vibratory feeder surface is made of 304 stainless steel, and the motor uses frequency and voltage regulation control to adapt to Hall effect devices 10 of different sizes, with an arrangement success rate of ≥99%.

[0053] 2. The first linear vibratory feeding module 3 feeds materials: it serves as a connector and delivers the Hall device 10 into position, maintaining it in a clampable state (i.e., exposing the component body 13). Its transmission track is the same as that of the second linear vibratory feeding module 9, adopting a double-track anti-jamming design, and its speed is synchronized with the output frequency of the vibratory feeder.

[0054] 3. First imaging station 4: Polarity detection: Identifying side A of the Hall device 10. Side A identification: The polarity mark of the device is captured by a side CCD (i.e., as shown in the image). Figure 10 (Character face in the image), 12MP high-speed camera + ring light source 40, recognition accuracy ±0.05mm (industry standard ±0.1mm).

[0055] 4. The first flipping module 5 operates by flipping the Hall effect device 10 180 degrees. After flipping the device, the next step of taking pictures of side B is performed. The rotary cylinder 20 and gripper 23 operate, and the 180° flipping time is ≤0.15 seconds (≥0.3 seconds for general equipment). The significance of this step is that the flipping action depends on the recognition result of side A. If side B recognition is performed in advance, the recognition of feature points on side A will be missed, and the material cannot be intercepted when misuse occurs.

[0056] 5. Second photo station 6: Reconfirm polarity by identifying the B-side of Hall effect device 10. The B-side of the device is identified, and the polarity mark is captured by a side CCD. The dual-camera, dual-sided photo-taking redundancy design achieves a 99.99% orientation accuracy rate, breaking through the industry's 99% bottleneck. The significance of this step is that B-side identification must be performed after flipping, and feature points are identified on both sides to ensure that the component is not used incorrectly. B-side verification must be performed after the flipper #1 is activated; otherwise, the flipping effect cannot be detected.

[0057] 6. The second flip module 7 works as follows: Based on the above identification results, it determines whether to perform the final flip channel flip, that is, based on the identification results of the previous step and the patch requirements, it decides whether to flip again to ensure 100% consistency of omnidirectional output.

[0058] 7. Cutting Station Operation: Cuts off the paper tape and excess length of pins 14 on the Hall device 10. The pin 14 length is precisely adjusted to the set value using an adjustable cutting blade with a tolerance of ±0.1mm (conventional ±0.3mm).

[0059] 8. Second vertical vibration feed module 9: Serves as a connector and delivers the Hall effect device 10 to its position, ensuring the pick-and-place machine can pick it up. It buffers the feed to the pick-and-place machine interface, with a speed adapted to the machine's cycle time to eliminate vibration transmission.

[0060] It should be noted that the control system HMI connects to the vision module via industrial Ethernet, coordinates the timing logic of vision, flipping, and lead clipping through a PLC, and achieves system feature point recognition through computer host control. The feature points can be flexibly customized using components. The control system HMI (Human-Machine Interface) is a hardware or software system used for human-machine interaction in industrial automation, allowing operators to monitor and control equipment and processes. It is commonly referred to in the industry as a human-machine interface, operated via a computer control panel. This control technology is existing and will not be elaborated upon here.

[0061] This application provides an automatic orientation correction and lead-cutting feeder for Hall effect sensor devices (HERS) in surface mount technology (SMT) processes, along with its operation method. By integrating visual recognition, a pneumatic flipping mechanism, and an automatic lead-cutting mechanism, it completely eliminates manual intervention, enabling continuous orientation feeding and lead cutting for polarity-sensitive components such as Hall effect sensors, meeting the stringent efficiency and accuracy requirements of high-speed SMT processes. It achieves integrated online processing of "recognition-flipping-lead cutting-output" in the feeding field, overcoming the final technical barrier that automated placement equipment for polarity-sensitive devices cannot recognize, making fully unmanned SMT production of high-value components such as Hall effect sensors possible. It solves the core pain points of existing technologies, such as low efficiency, interrupted continuity, and poor orientation consistency due to manual orientation. The entire process is closed-loop automated: from bulk material input to SMT-ready output, saving 4 operators; zero-defect orientation control: dual-level vision (A / B side) + dual flipper redundancy → zero reverse placement defects; improved economy: lead cutting accuracy ±0.1mm → annual reduction in rework costs of 350,000 RMB / million pieces.

[0062] The beneficial effects of this invention are as follows: This novel structure does not require manual intervention for direction correction, can automatically identify polarity online, and can ensure that the polarity of the Hall device 10 is 100% correct. Due to the use of automated operation, the quality consistency of the finished product is better, and there will be no hidden dangers to the quality of the product. Automatic placement can be achieved, which improves production efficiency.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
