[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] This application provides a component delivery and detection system, such as Figures 1-9As shown, it includes a conveying mechanism 7 and a positioning polarity adjustment mechanism 8. The conveying mechanism 7 includes a suction nozzle assembly 71 for conveying components. The positioning polarity adjustment mechanism 8 includes a positioning module 81 and a polarity testing module 83. The positioning module 81 is used to position the components, and the polarity testing module 83 tests the polarity of the positioned components by conducting current through the electrode plates.

[0021] The component conveying and testing system provided in this embodiment, through the coordinated operation of the conveying mechanism 7 and the positioning polarity adjustment mechanism 8, ensures the consistency of component positions through mechanical calibration by the positioning module 81. The polarity testing module 83 forms a circuit by contacting the component terminals with the electrode plate, applies a low-voltage current to detect the conduction state, and judges the polarity performance through the current response, effectively screening out defective products, improving the yield rate of output components, ensuring continuous and stable operation of the equipment, and realizing fully automatic conveying and testing from bulk materials to qualified components. There is no need for manual intervention in packaging or sorting processes, replacing the traditional tape or pallet packaging method, reducing the consumption of packaging materials and labor costs. It can also be compatible with the feeding of equipment such as chip mounters and die bonders, and supports the direct processing of bulk materials of various components (such as discrete devices, chips and components, etc.), saving the consumption of packaging materials and manual sorting, reducing waste generation and energy waste, and reducing the cost of tape, auxiliary materials and labor.

[0022] The component conveying and detection system provided in this embodiment, in one possible implementation, is as follows: Figure 5 As shown, the positioning polarity adjustment mechanism 8 also includes a positioning drive motor 82, which is connected to the positioning module 81 and is used to drive the positioning module 81 to clamp and release the element.

[0023] The positioning drive motor 82 drives the positioning module 81 to perform clamping or releasing actions on the component, ensuring that the component is stably fixed in the preset positioning position before testing. The mechanical positioning process is fully automated, avoiding uneven clamping force or position error caused by manual intervention, ensuring the consistency of batch operations, eliminating the interference of position deviation on polarity detection, avoiding misjudgment caused by component offset, and reducing the invalid operation of subsequent testing modules.

[0024] In one possible implementation, such as Figure 5 As shown, the positioning module 81 includes two symmetrical right-angle modules. The positioning drive motor 82 drives the two right-angle modules to move away from each other to form a receiving cavity for the component to be placed in. The positioning drive motor 82 drives the two right-angle modules to move closer to each other to clamp and position the component located in the receiving cavity.

[0025] The system utilizes a positioning drive motor 82 to drive the synchronous opening and closing of two symmetrical right-angle modules, dynamically forming an adjustable accommodating cavity space to meet the precise positioning requirements of components of different sizes. After the component is placed inside, the right-angle modules close to form a mechanical clamping surface, eliminating any positional deviation of the component before polarity testing. The symmetrical design of the right-angle modules provides bidirectional clamping force, ensuring that the component maintains a fixed posture during polarity testing and avoiding misjudgments or poor contact caused by displacement during the test.

[0026] Understandably, the right-angle module adopts a standardized interface design, which makes it easy to replace according to the component size and adapt to the positioning needs of various components such as discrete devices, chips and parts.

[0027] In one possible implementation, such as Figure 6 As shown, after the components are tested by the polarity test module 83, they are divided into good components and defective components. The positioning polarity adjustment mechanism 8 also includes an angle rotation module 84 and a rotary drive motor 85. The angle rotation module 84 can rotate to adjust the position of the components. The rotary drive motor 85 is connected to the angle rotation module 84 and is used to drive the angle rotation module 84 to rotate. A defective product discharge port 86 is provided on the movement path of the angle rotation module 84. When the defective component is moved to the defective product discharge port 86 with the angle rotation module 84, it is disengaged from the angle rotation module 84.

[0028] The angle rotation module 84 is linked with the polarity test module 83. After the components complete the electrode performance test, they are classified. Good components are kept at the original angle and enter the next process, while defective components are rotated by a certain angle through the angle rotation module 84 and precisely guided to the defective product discharge port 86, thus achieving a seamless connection from detection to sorting.

[0029] In one possible implementation, such as Figure 4 and Figure 7 As shown, the conveying mechanism 7 includes a suction nozzle assembly 71 and a rotary cam 72. The suction nozzle assembly 71 is mounted on the rotary cam 72 and includes a first suction nozzle 711, a second suction nozzle 712, and a third suction nozzle 713. The first suction nozzle 711 is used to convey components from the sorting and feeding channel 62 of the sorting and feeding mechanism 6 to the positioning module 81. The second suction nozzle 712 is used to convey components from the positioning module 81 to the angle rotation module 84. The third suction nozzle 713 is used to convey components from the polarity testing module 83 to the linear vibration feeding channel 91 of the linear feeding mechanism 9. The rotary cam 72 drives the first suction nozzle 711, the second suction nozzle 712, and the third suction nozzle 713 to move back and forth synchronously.

[0030] The three sets of suction nozzles move synchronously through the rotating cam 72, forming a closed-loop transport route for sorting, positioning, polarity testing and discharge. The first suction nozzle 711 transports the component from the sorting and feeding mechanism 6 to the positioning station. After the component is clamped and positioned at the positioning station, its polarity is tested. The second suction nozzle 712 is used to transport the defective component that fails the test from the positioning station to the angle rotation module 84. The defective component is rotated to the defective discharge port 86 by the angle rotation module 84. The third suction nozzle 713 transports the good component that passes the test from the positioning station to the linear feeding channel 91 of the linear feeding mechanism 9.

[0031] In one possible implementation, such as Figure 2 As shown, the component conveying and detection system also includes a filter funnel mechanism 5, which includes a funnel 51 and a filter screen 52. The funnel 51 is used to gather and convey several components to the filter screen 52. The filter screen 52 is set at the output end of the funnel 51 to separate components and impurities, and convey the components to the sorting and feeding mechanism 6.

[0032] Among them, the funnel 51 adopts a top-to-bottom tapering flow channel design, which allows the bulk components to naturally converge to the filter screen 52 under the action of gravity. The screen aperture is precisely matched with the component size, and the components can move along the filter screen 52 to the sorting and feeding mechanism 6. The filter screen 52 can effectively filter dust, debris and other impurities.

[0033] In one possible implementation, such as Figure 3 As shown, the component conveying and detection system also includes a sorting and feeding mechanism 6 connected to the output end of the filter funnel mechanism 5. The sorting and feeding mechanism 6 includes a vibrating sorting plate 61 and a sorting and feeding channel 62. The sorting and feeding channel 62 is located at the output end of the vibrating sorting plate 61. The vibrating sorting plate 61 vibrates to send the components one by one to the sorting and feeding channel 62.

[0034] Among them, the filter funnel mechanism 5 has a filter and switch control structure. When the sorting and feeding mechanism 6 senses that there are not enough components, it sends an instruction to the host to open the feeding mode. After opening, the components can separate impurities and foreign objects through the filter screen 52 and flow into the vibrating distribution plate 61. The sorting and feeding mechanism 6 generates a vibration frequency to gradually send the components to the sorting and feeding channel 62, realizing the first stage of feeding.

[0035] In one possible implementation, such as Figure 7 As shown, the component conveying and detection system also includes a linear feeding mechanism 9, which includes a linear vibration feeding channel 91 and a linear vibration drive motor 92. The conveying mechanism 7 transports the good components to the linear vibration feeding channel 91. The linear vibration drive motor 92 is connected to the linear vibration feeding channel 91. The plasma air supply module 4 blows air toward the components to transport the components along the vibrating linear vibration feeding channel 91 to the picking part 103 of the picking and identification mechanism 10.

[0036] Among them, the direct vibration drive motor 92 generates high-frequency micro-amplitude vibration, which causes the direct vibration feeding channel 91 to form a directional mechanical wave, and the component achieves unidirectional forward movement under the action of the difference in friction coefficient.

[0037] The plasma air supply module 4 can be set to deliver plasma air to the components, which can eliminate the electrostatic adsorption of the components and make the thin components stably attached to the direct vibration feeding channel 91, thereby improving the stability of the conveying.

[0038] In one possible implementation, such as Figure 9 As shown, the component conveying and detection system also includes a picking and identification mechanism 10 connected to the output end of the linear feeding mechanism 9. The picking and identification mechanism 10 includes a picking section 103, a component presence / absence fiber optic detection sensor 102, and a nozzle detection fiber optic sensor 101. The picking section 103 includes a first picking position 1031 and a second picking position 1032. The component presence / absence fiber optic detection sensor 102 is used to detect the presence or absence of components in the picking section 103. After the nozzle detection fiber optic sensor 101 detects that the picking nozzle is in place, the negative pressure module releases the component, and the picking nozzle transports the component to the next station. When the component presence / absence fiber optic detection sensor 102 detects that there is a component on the picking section 103, the negative pressure module adsorbs and positions the component located at the first picking position 1031 and the second picking position 1032. When the component presence / absence fiber optic detection sensor 102 detects that there is no component on the picking section 103, a feeding command is sent for cyclical operation.

[0039] When the fiber optic component detection sensor 102 simultaneously scans the dual-station status of the first pick-up position 1031 and the second pick-up position 1032, the vacuum path of the negative pressure module is activated. That is, a vacuum is generated at the bottom of the first pick-up position 1031 and the second pick-up position 1032 to attract the first and second components, realizing the adsorption and continuous feeding of components in the dual-station system. At the same time, an instruction is sent to the pick-up machine to indicate that the material is ready. When the pick-up machine receives the instruction, the pick-up nozzle arrival signal triggers the equipment to send an instruction to release the vacuum adsorption state of the first component. The pick-up nozzle then moves the component to the next station. When the fiber optic component detection sensor 102 detects that there is no material at the first pick-up position 1031, an instruction is sent to the equipment to feed the component forward. This cycle is repeated to achieve continuous feeding.

[0040] The component conveying and detection system provided in this embodiment includes a filter funnel mechanism 5, a sorting and feeding mechanism 6, a conveying mechanism 7, a positioning polarity adjustment mechanism 8, a linear feeding mechanism 9, and a material picking and identification mechanism 10 connected in sequence. Through the coordinated operation of the above multiple functional modules, the equipment is ensured to operate continuously and stably, realizing fully automatic conveying and detection from bulk materials to qualified components. No manual intervention is required in the packaging or sorting process, replacing the traditional tape or pallet packaging method, reducing the consumption of packaging materials and labor costs.

[0041] In one possible implementation, such as Figure 1 As shown, the component conveying and detection system includes a support frame 1, a support platform 3, and an operation interface 2. The support platform 3 is mounted on the support frame 1, and the operation interface 2 is mounted on the support platform 3.
