Description

Technical Field

[0001] This invention relates to the field of optoelectronic product testing technology, specifically to a feeding device and feeding method. Background Technology

[0002] In the manufacturing process of optoelectronic products, testing is a crucial step in ensuring product quality and performance. Optoelectronic product testing typically includes two main aspects: visual inspection and electrical performance testing, aiming to comprehensively evaluate whether the product's various indicators meet design requirements. In the testing process, the loading stage, as the starting point of the testing procedure, has a vital impact on the overall testing results in terms of efficiency and accuracy. Existing technologies mainly employ two loading methods: vibratory feeder loading and tray loading.

[0003] Vibratory feeder loading is a device that uses vibration to arrange and transport products to a loading station in a specific direction and order. While this method offers advantages in automation, it presents significant drawbacks for optoelectronic products. Specifically, optoelectronic products typically have high requirements for surface quality, especially those with two optical filters, whose cleanliness directly affects their optical performance. However, during vibratory feeder loading, products collide and rub against each other, easily causing scratches and even contaminating the optical filters. This severely impacts the product's appearance and optical performance, reducing yield.

[0004] Tray loading involves placing pre-cut individual products from the previous process into a tray manually or using specialized equipment, which then transports the product to the loading station. While this method helps prevent collisions between products to some extent, it is relatively cumbersome and requires additional manpower or equipment. Specifically, accurately placing individual products into the tray is not only time-consuming and labor-intensive but also increases production costs. Furthermore, as production scales up, the management and cleaning of the trays become crucial tasks, further increasing the complexity and cost of production management. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a feeding device and feeding method that can feed materials one by one in sequence, avoid material collision and friction, improve the yield of material appearance, reduce production costs, and improve feeding efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides a feeding device, comprising at least: The mounting assembly includes at least a base for supporting a UV film frame and a first drive mechanism. The output end of the first drive mechanism is connected to the base for adjusting the position of the base. The base is provided with a through clearance channel. The ejector assembly includes at least an ejector pin located below the base, and a second driving mechanism for driving the ejector pin through the clearance channel to lift the material located on the UV film; The extraction mechanism includes at least a suction nozzle corresponding to the top pin for sucking up material, and a third driving mechanism for driving the suction nozzle to move, thereby feeding material.

[0007] In a preferred embodiment, the system further includes a data acquisition unit and a control unit; The data acquisition unit is used to acquire material position data on the UV film located on the base, and transmit the position data to the control unit; The control unit is used to control the first driving mechanism to adjust the position of the base so that the material on the UV film moves above the ejector pin based on the position data, control the second driving mechanism to drive the ejector pin to lift the material away from the UV film, and control the third driving mechanism to drive the suction nozzle to move above the material on the UV film to pick up the material for feeding.

[0008] In a preferred embodiment, the data acquisition unit includes at least an industrial camera located above the base, a support frame for mounting the industrial camera, and a light source adapted to the lens of the industrial camera.

[0009] In a preferred embodiment, the first driving mechanism includes a first driving unit, which includes a driven pulley mounted below the base, a first driving element, a driving pulley mounted at the output end of the first driving element, and a transmission belt for connecting the driving pulley and the driven pulley. The first driving element drives the base to rotate through the driving pulley, the transmission belt, and the driven pulley. The rotation center axis of the base is parallel to the direction of movement of the ejector pin.

[0010] In a preferred embodiment, the mounting assembly further includes a base plate located below the driven pulley, the base plate being provided with a clearance groove matching the clearance channel, an annular positioning member matching the driven pulley being installed between the base plate and the driven pulley, the annular positioning member having a positioning groove on its outer peripheral surface, the base plate being provided with at least one positioning roller adapted to the positioning groove, and at least one omnidirectional ball adapted to the lower end surface of the annular positioning member.

[0011] In a preferred embodiment, the first driving mechanism further includes a second driving unit and a third driving unit mounted on the output end of the second driving unit; The output terminal of the third driving unit is connected to the substrate and is used to drive the substrate to move the base along the rotation center axis of the base. The second drive unit is used to drive the third drive unit to move the base along a direction perpendicular to the rotation center axis of the base.

[0012] In a preferred embodiment, the ejector pin assembly further includes a mounting plate, a movable plate, a connecting shaft of the ejector pin being fixedly connected to the movable plate at one end and mounted on the other end; The second drive mechanism includes a second drive element and a crank-slider mechanism for connecting the output end of the second drive element to the moving plate; The extension direction of the connecting shaft is parallel to the movement direction of the moving plate. The second driving element drives the moving plate to move relative to the mounting plate through the crank-slider mechanism, thereby driving the pin mounted on the connecting shaft to move.

[0013] In a preferred embodiment, the ejector pin assembly further includes a fourth driving mechanism, the output end of which is connected to the mounting plate and is used to drive the mounting plate to move along the direction of the ejector pin movement.

[0014] In a preferred embodiment, the extraction mechanism further includes a robotic arm and a pneumatic unit for providing suction to the nozzle, the nozzle being mounted on the free end of the robotic arm, and the output end of the pneumatic unit being connected to the nozzle.

[0015] The present invention also provides a feeding method for the feeding device as described above, comprising at least the following steps: Step S01: After cutting and molding, the UV film frame is installed on the base of the mounting assembly. Multiple materials are attached to the UV film in an array. Step S02: Adjust the position of the base using the first driving mechanism so that the material is directly above the ejector pin; Step S03: The second driving mechanism drives the ejector pin to pass through the clearance channel and lift the material, causing the material to partially detach from the UV film. At the same time, the third driving mechanism drives the suction nozzle to move above the material, working together with the ejector pin to complete the material suction. Step S04: The suction nozzle is driven by the third drive mechanism to move and feed the material. Step S05: Repeat steps S02-S04 above to complete the feeding of all materials adhering to the UV film.

[0016] The feeding device and feeding method of the present invention have the following advantages compared with the prior art: (1) The feeding device of the present invention includes at least a mounting assembly, a pin assembly, and an extraction mechanism. The mounting assembly includes at least a base for supporting the UV film frame and a first driving mechanism. With this structural design, the base supports the UV film frame, and the material is supported by the UV film, avoiding mutual collision and friction of the material during the conveying process. This eliminates the risks of scratches, abrasions, and filter hole contamination caused by physical contact between materials in the prior art feeding method. This is crucial for optoelectronic product materials (especially products with filter holes) that have high requirements for surface cleanliness and appearance quality, and can significantly improve the yield of product materials. The output end of the first drive mechanism is connected to the base and is used to adjust the position of the base. After cutting, molding, and degumming, the material on the UV film becomes multiple independent individual materials. By adjusting the position of the base, the position of each individual material is adjusted. In conjunction with the ejector assembly and the extraction mechanism, the material on the UV film is fed continuously, one by one. This eliminates the tedious steps of manually or using special equipment to place each individual material into the tray, greatly simplifying the operation process, improving feeding efficiency, reducing reliance on manual labor and related labor costs, and avoiding the investment in expensive tray placement equipment. The base is equipped with a through clearance channel, which provides a path for the ejector pins in the ejector assembly to pass through, allowing the ejector pins to smoothly pass under the base and lift the material on the UV film, achieving separation of the material from the UV film. This provides convenient conditions for the subsequent extraction mechanism to pick up the material and ensures a smooth feeding process.

[0017] The ejector assembly includes at least an ejector pin located below the base and a second drive mechanism. The extraction mechanism includes at least a suction nozzle corresponding to the ejector pin for picking up material. The ejector pin smoothly lifts the material from the UV film from bottom to top, and the suction nozzle picks it up from above. The material remains in a controlled and independent state throughout the entire separation and transfer process. The coordinated non-contact material handling of the ejector assembly and extraction mechanism enables sequential and continuous separation and feeding of materials, avoiding the risks associated with contact, collision, and friction between materials during feeding. It also eliminates the uncertainty, inefficiency, and potential damage caused by manual operation, ensuring the stability and consistency of the production rhythm, making it particularly suitable for large-scale continuous production.

[0018] (2) The feeding device of the present invention further includes a data acquisition unit and a control unit. The data acquisition unit is used to acquire the position data of the material on the UV film located on the base and transmit the position data to the control unit; the control unit is used to control the first driving mechanism to adjust the position of the base so that the material on the UV film moves above the ejector pin, control the second driving mechanism to drive the ejector pin to lift the material off the UV film, and control the third driving mechanism to drive the suction nozzle to move above the material on the UV film to pick up the material for feeding. The data acquisition unit accurately acquires the position data of the material on the UV film located on the base, providing accurate information to the control unit. Based on this position data, the control unit controls the first driving mechanism to adjust the position of the base so that the material moves accurately above the ejector pin, avoiding feeding failure or repeated operation due to inaccurate positioning, and improving the accuracy of feeding. This structural design unifies and coordinates the actions of the first, second, and third drive mechanisms, automating the feeding process. The entire process is fast and continuous, reducing manual operation time and errors, greatly improving feeding efficiency, and meeting the feeding speed requirements of large-scale production. On the other hand, because the data acquisition unit can accurately collect the position data of materials of different specifications, the control unit can flexibly adjust the action parameters of each drive mechanism based on this data, enabling the feeding device to adapt to the feeding needs of optoelectronic products of different sizes, shapes, and arrangements, thus enhancing the versatility and adaptability of the device.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element 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 invention.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] Example One type of feeding device in this embodiment, such as Figure 1As shown, it includes at least a mounting assembly 1, a pin assembly 2, and an extraction mechanism 3. The mounting assembly includes at least a base 11 for supporting the UV film frame and a first drive mechanism 12. With this structural design, the base supports the UV film frame, and the UV film carries the material, avoiding mutual collision and friction between materials during the conveying process. This eliminates the risks of scratches, abrasions, and filter hole contamination caused by physical contact between materials in existing feeding methods. This is crucial for optoelectronic product materials (especially products with filter holes) that have high requirements for surface cleanliness and appearance quality, and can significantly improve the yield of product materials.

[0025] The output end of the first drive mechanism is connected to the base for adjusting the base position. The base is equipped with a through clearance channel 111. After cutting, molding, and degumming, the material on the UV film becomes multiple independent individual materials. By adjusting the base position, the position of each individual material is adjusted. In conjunction with the ejector assembly and the extraction mechanism, the material on the UV film is fed sequentially and continuously, eliminating the tedious steps of manually or using specialized equipment to place each individual material into the tray. This greatly simplifies the operation process, improves feeding efficiency, reduces reliance on manual labor and related labor costs, and avoids the investment in expensive tray placement equipment. The through clearance channel in the base provides a path for the ejector pins in the ejector assembly to pass through, allowing them to smoothly pass under the base and lift the material on the UV film, achieving separation of the material from the UV film. This facilitates the subsequent extraction mechanism's material feeding and ensures a smooth feeding process.

[0026] like Figure 2 and Figure 3 As shown, the first drive mechanism 12 includes a first drive unit 121, which includes a driven pulley 1211 mounted below the base 11, a drive element 1212, a drive pulley 1213 mounted at the output end of the drive element 1, and a transmission belt 1214 connecting the drive pulley and the driven pulley. The drive element 1 drives the base 11 to rotate via the drive pulley, transmission belt, and driven pulley. By controlling parameters such as the number of rotations, speed, and acceleration of the drive element 1, precise control of the base rotation can be achieved, ensuring that the base can rotate according to a preset trajectory and angle, so that the material on the UV film on the base can be accurately moved to the designated position, providing precise positional assurance for subsequent ejector pin lifting and nozzle suction of material.

[0027] In this embodiment, the rotation center axis of the base 11 is parallel to the direction of movement of the ejector pin. This arrangement allows the material's horizontal position adjustment after the base rotates to better coordinate with the vertical lifting action of the ejector pin. By rotating the base, the material can be accurately adjusted to be directly above the ejector pin, ensuring that the ejector pin can lift the material vertically and stably. This avoids problems such as lifting failure or material damage caused by material position deviation, thus improving the success rate and reliability of feeding.

[0028] like Figure 4 As shown, in this embodiment, the base 11 is provided with a clamping device 112. The clamping device 112 includes a locking block 1121 that is spaced apart on the upper surface of the base around the clearance channel, a rotating block 1122 that is correspondingly provided with the locking block and rotatably connected to the upper surface of the base, and a driving element 1123. The driving element 1123 is used to drive the rotating block to rotate and cooperate with the locking block to clamp the UV film outer frame onto the base.

[0029] like Figure 3 As shown, the mounting assembly 1 also includes a base plate 13 located below the driven pulley. The base plate is provided with a clearance groove 131 that matches the clearance channel 111, ensuring that the ejector pin can pass smoothly through the clearance channel and clearance groove without being blocked by the base plate. On the one hand, this ensures the normal rotational movement of the base; on the other hand, it realizes a compact layout of the internal structure of the device, saves space, and improves the overall integration of the device.

[0030] An annular positioning member 132, matching the driven pulley, is installed between the base plate 13 and the driven pulley. For example... Figure 4 As shown, a positioning groove 1321 is provided on the outer circumferential surface of the annular positioning member. At least one positioning roller 133 adapted to the positioning groove is mounted on the base plate, effectively restricting the radial movement of the driven pulley, preventing eccentricity or wobbling during operation, ensuring transmission accuracy between the driven and driving pulleys, and enabling the base to rotate along a predetermined trajectory. At least one universal ball 134 adapted to the lower end face of the annular positioning member is mounted on the base plate, providing stable support for the annular positioning member. During the rotation of the driven pulley, the universal ball can rotate freely, converting the sliding friction between the annular positioning member and the base plate into rolling friction, greatly reducing axial friction, making the axial movement of the driven pulley more flexible, and simultaneously reducing heat and wear generated by friction, thus improving the operational reliability and service life of the device.

[0031] In this embodiment, the substrate 13 is provided with three positioning rollers 133 spaced apart along the circumferential direction of the annular positioning member 132, and three universal balls 134 spaced apart along the circumferential direction of the annular positioning member 132.

[0032] like Figure 3As shown, the first driving mechanism 12 also includes a second driving unit 122 and a third driving unit 123 mounted on the output end of the second driving unit. The output end of the third driving unit is connected to the substrate 13 and is used to drive the substrate to move the base 11 along the direction of the base rotation center axis. The second driving unit is used to drive the third driving unit to move the base 11 along the direction perpendicular to the base rotation center axis. This structural design allows the base to move flexibly in multiple directions in three-dimensional space, meeting the material feeding requirements of optoelectronic products with different shapes, sizes, and placement positions, and improving the flexibility and adaptability of the feeding device.

[0033] like Figure 5 As shown, the ejector assembly 2 includes at least an ejector pin 21 located below the base, and a second drive mechanism 22, which drives the ejector pin to pass through the clearance channel 111 and lift the material located on the UV film. Figure 6 As shown, the extraction mechanism 3 includes at least a suction nozzle 31 corresponding to the ejector pin 21 for picking up material, and a third drive mechanism 32. The third drive mechanism drives the suction nozzle to move, thereby feeding the material. The ejector pin smoothly lifts the material from the UV film from bottom to top, and the suction nozzle picks it up from above. The material remains in a controlled and independent state throughout the entire separation and transfer process. By adopting a cooperative non-contact material handling method between the ejector pin assembly and the extraction mechanism, the material is continuously separated and fed sequentially, avoiding the risks caused by contact, collision, and friction between materials during the feeding process. At the same time, it eliminates the uncertainty, inefficiency, and potential damage caused by human operation, ensuring the stability and consistency of the production rhythm, and is particularly suitable for large-scale continuous production.

[0034] In this embodiment, as Figure 5 As shown, the ejector pin assembly 2 also includes a mounting plate 23, a movable plate 24, and a connecting shaft 25 with one end fixedly connected to the movable plate and the other end mounted with an ejector pin 21. The second drive mechanism 22 includes a second drive element 221 and a crank-slider mechanism 222 for the output end of the second drive element and the movable plate. The extending direction of the connecting shaft is parallel to the moving direction of the movable plate. The second drive element drives the movable plate to move relative to the mounting plate through the crank-slider mechanism, thereby moving the ejector pin mounted on the connecting shaft.

[0035] In this embodiment, the ejector pin assembly also includes a fourth driving mechanism 26. The output end of the fourth driving mechanism is connected to the mounting plate 23 and is used to drive the mounting plate to move along the direction of ejector pin movement.

[0036] like Figure 6 As shown, the extraction mechanism 3 also includes a robotic arm 33 and a pneumatic unit 34 for providing suction to the nozzle. The nozzle is mounted on the free end of the robotic arm, and the output end of the pneumatic unit is connected to the nozzle.

[0037] like Figure 7 and Figure 8 As shown, the feeding device also includes a data acquisition unit 4 and a control unit. The data acquisition unit is used to collect the position data of the material on the UV film located on the base and transmit the position data to the control unit. Based on the position data, the control unit controls the first drive mechanism 12 to adjust the position of the base so that the material on the UV film moves above the ejector pin 21, controls the second drive mechanism 22 to drive the ejector pin to lift the material out of the UV film, and controls the third drive mechanism 32 to drive the suction nozzle to move above the material on the UV film to pick up the material for feeding. The data acquisition unit accurately collects the position data of the material on the UV film on the base, providing accurate information to the control unit. Based on this position data, the control unit controls the first drive mechanism to adjust the position of the base so that the material moves accurately above the ejector pin, avoiding feeding failures or repeated operations due to inaccurate positioning, and improving the accuracy of feeding. This structural design unifies and coordinates the actions of the first, second, and third drive mechanisms, automating the feeding process. The entire process is fast and continuous, reducing manual operation time and errors, greatly improving feeding efficiency, and meeting the feeding speed requirements of large-scale production. On the other hand, because the data acquisition unit can accurately collect the position data of materials of different specifications, the control unit can flexibly adjust the action parameters of each drive mechanism based on this data, enabling the feeding device to adapt to the feeding needs of optoelectronic products of different sizes, shapes, and arrangements, thus enhancing the versatility and adaptability of the device.

[0038] In this embodiment, the data acquisition unit 4 includes at least an industrial camera 41 located above the base 11, a support frame 42 for mounting the industrial camera, and a light source 43 adapted to the lens of the industrial camera.

[0039] This embodiment also provides a feeding method for any of the feeding devices described above, which includes at least the following steps: Step S01: After cutting and molding, the UV film frame is installed on the base of the mounting component 1. Multiple materials are attached to the UV film in an array. Step S02: Adjust the position of the base 11 through the first drive mechanism 12 so that the material is directly above the ejector pin 21; In step S03, the second driving mechanism 22 drives the ejector pin to pass through the clearance channel 111 and lift the material, causing the material to partially detach from the UV film. At the same time, the third driving mechanism 32 drives the suction nozzle 31 to move above the material and work with the ejector pin to complete the material suction. Step S04: The third drive mechanism 32 drives the suction nozzle to move and drive the material to complete the feeding process. Step S05: Repeat steps S02-S04 to complete the feeding of all materials adhering to the UV film.

[0040] In summary, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
