[0001] This utility model relates to the technical field of electronic component processing, and in particular to a testing and conveying mechanism suitable for electronic components. Background Technology

[0002] During the production and processing of electronic components, testing is required to ensure that the functions of the electronic components meet the factory requirements.

[0003] like Figure 2 As shown, gripping components, which are vacuum suction cups, are mounted on the bottom of both the loading / unloading robotic arm and the pick-and-place robotic arm via mounting brackets. These vacuum suction cups directly grip the electronic components. However, using only vacuum suction cups cannot achieve automatic unloading or positioning correction of the components.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a testing and conveying mechanism for electronic components, making it more valuable for industrial applications. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a testing and conveying mechanism suitable for electronic components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A testing and conveying mechanism for electronic components includes a work platform on which a feeding tray, a loading and unloading robotic arm, a slide rail platform, a pick-and-place robotic arm, a testing module, and a receiving tray are mounted. A feeding tray and a receiving tray are installed on the front left and front right sides of the working platform, respectively. Loading and unloading robotic arms are installed on the working platform on the side of the feeding tray and the receiving tray, and a test module is installed on the working platform behind the feeding tray and the receiving tray. A slide rail platform and a picking and placing robotic arm are installed on the working platform on the side of the test module. Both the loading / unloading robotic arm and the pick-and-place robotic arm are equipped with gripping components mounted on the bottom via mounting brackets. The gripping components, from top to bottom, include an upper mounting base and a lower mounting base. The upper and lower mounting bases are connected together by several connecting rods. A suction nozzle is mounted at the bottom of the upper mounting base, and a vacuum connector connected to the suction nozzle is mounted at the top of the upper mounting base. An air pipe is mounted on the vacuum connector. A suction nozzle mounting groove for accommodating the suction nozzle is opened in the lower mounting base directly below the suction nozzle. A pusher cylinder mounting slot is provided at the bottom of the lower mounting base outside the nozzle mounting slot. A pusher cylinder is installed in the pusher cylinder mounting slot. The pusher cylinder drives the pusher block to move up and down and freely pass through the pusher through hole below.

[0007] As a further improvement of this utility model, both the nozzle and the nozzle mounting groove are annular structures. A partition is provided in the middle of the inner side of the nozzle mounting groove, and a detection sensor is installed in the detection sensor mounting groove at the bottom of the partition.

[0008] As a further improvement of this utility model, the upper mounting base and the lower mounting base are fixedly connected together by a connecting rod.

[0009] As a further improvement of this utility model, the upper mounting base and the lower mounting base are movably connected together by a connecting rod, and a spring is installed on the connecting rod between the upper mounting base and the lower mounting base.

[0010] As a further improvement of this utility model, pads are installed at the bottom of the lower mounting base outside the pusher hole and at the bottom of the pusher block.

[0011] As a further improvement of this utility model, the pad is a rubber pad or a silicone pad.

[0012] As a further improvement of this utility model, the vacuum connector is detachably mounted on the upper mounting base, and the air pipe is a connecting hose structure.

[0013] As a further improvement of this utility model, the number of pusher cylinders is at least two.

[0014] By means of the above solution, this utility model has at least the following advantages: This invention uses a suction nozzle to adsorb electronic components while simultaneously using a pusher cylinder to precisely unload the electronic components after testing, ensuring the positional accuracy of the electronic components.

[0015] The nozzle and nozzle mounting groove of this invention both adopt a ring structure. The partition block in the middle of the inner side integrates a detection sensor, which can monitor the adsorption status of the component in real time and avoid misjudgment caused by component position deviation during the test.

[0016] The vacuum connector of this invention is detachable, making maintenance and replacement convenient; the flexible tubing enhances the flexibility of the robotic arm's movement and avoids fatigue rupture of the tubing caused by rigid connections.

[0017] The above description is only an overview of the technical solution of this utility model.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] The first embodiment of this utility model: like Figure 1 As shown, a testing and conveying mechanism for electronic components in this embodiment includes a work platform 1, on which a feeding tray 2, a loading and unloading robotic arm 3, a slide rail platform 4, a pick-and-place robotic arm 5, a testing module 6, and a receiving tray 7 are mounted.

[0025] The positions of the aforementioned components on work platform 1 are as follows: Feeding tray 2 and receiving tray 7 are installed on the front left and front right sides of the working platform 1, respectively. Initially, the electronic components to be processed are placed in the feeding tray 2, and then the tested electronic components are placed in the receiving tray 7.

[0026] Loading and unloading robotic arms 3 are respectively installed on the work platform 1 on one side of the feeding tray 2 and the receiving tray 7. The gripping component on the loading and unloading robotic arm 3 on the feeding tray 2 side removes the electronic components from the feeding tray 2, moves them to the rear, and places them on the slide rail platform 4. The gripping component on the loading and unloading robotic arm 3 on the receiving tray 7 side removes the detected electronic components located on the slide rail platform 4, moves them again, and places them in the receiving tray 7. The aforementioned loading and unloading robotic arms 3 have operating modes in the left-right direction, the front-back direction, and the vertical direction, and the aforementioned operating modes can be realized by conventional motion modules in the prior art.

[0027] A test module 6 is installed on the working platform 1 behind the feeding tray 2 and the receiving tray 7. A slide rail platform 4 and a picking and placing robotic arm 5 are installed on the working platform 1 on one side of the test module 6.

[0028] Test module 6 is a conventional structure for testing electronic components in the prior art, namely test machine 10. The electronic component to be tested is placed in the test slot 11 on the test machine 10 for testing.

[0029] The slide rail platform 4 serves as a transfer mechanism for electronic components before and after testing. The slide rail platform 4 can move in the left and right directions. The pick-and-place robotic arm 5 serves as a transport mechanism for electronic components before and after testing. The pick-and-place robotic arm 5 can move in the front-back direction and the vertical direction. The above-mentioned operation mode can be achieved by conventional motion modules in the prior art.

[0030] like Figure 2 As shown, both the loading / unloading robotic arm 3 and the pick-and-place robotic arm 5 in the prior art have gripping components mounted on their bottoms via mounting brackets 8. These gripping components are vacuum suction cups 9, which are used to grip and process electronic components. However, using only vacuum suction cups for gripping cannot achieve automatic unloading or positioning correction of components.

[0031] like Figure 3 As shown, in this embodiment, the bottom of both the loading / unloading robotic arm 3 and the picking / placing robotic arm 5 are equipped with gripping components via mounting brackets 8. The gripping components include an upper mounting base 12 and a lower mounting base 17 from top to bottom, and the upper mounting base 12 and the lower mounting base 17 are fixedly connected together via connecting rods 16.

[0032] A suction nozzle 13 is installed at the bottom center of the upper mounting base 12. Above the suction nozzle 13, on the top of the upper mounting base 12, a vacuum connector 14 is installed, communicating with the adsorption chamber inside the suction nozzle 13. The vacuum connector 14 is detachably installed on the upper mounting base 12, and an air tube 15 with a connecting hose structure is installed on the vacuum connector 14. The use of a flexible air tube 15 to connect the vacuum connector to an external vacuum source allows the robotic arm to move freely in three-dimensional space, avoids rigid air tubes from bending fatigue fracture, and extends service life by more than 2 times.

[0033] The vacuum connector 14 is connected to the upper mounting base 12 by thread or quick-connect method. When the nozzle or air tube is blocked, it can be quickly disassembled for maintenance. Compared with traditional welding or adhesive connection, the maintenance efficiency is improved by more than 3 times.

[0034] A nozzle mounting groove 22 for accommodating the nozzle 13 is provided in the lower mounting base 17 directly below the nozzle 13. The bottom of the nozzle 13 is close to the bottom of the nozzle mounting groove 22, which does not affect the adsorption effect.

[0035] The nozzle 13 has an outer diameter of 8-12mm, an inner diameter of 4-6mm, and an annular width of 2-3mm to accommodate common electronic components (such as 0402 packaged resistors, QFN packaged chips, etc.).

[0036] The spacer 23 is made of polyoxymethylene (POM) or nylon and has a height of 3-5mm. The depth of the sensor mounting groove 24 at the bottom is 1.5-2mm, ensuring that the sensor 25 maintains a distance of 0.5-1mm from the component surface to avoid damage to the component caused by contact detection.

[0037] The nozzle 13 and nozzle mounting groove 22 adopt an annular structure, which increases the adsorption area and divides the nozzle into multiple independent adsorption areas by the partition 23. For example, for rectangular elements, the annular nozzle can form a uniform negative pressure distribution, improving adsorption stability by more than 20%.

[0038] The sensor mounting slot 24 at the bottom of the partition 23 integrates a fiber optic sensor or a pressure sensor 25, which can monitor in real time whether the component is correctly adsorbed (such as abnormal vacuum or component tilt), and trigger the robotic arm to adjust or alarm through signal feedback to avoid interruption of the test process.

[0039] The detection sensor 25 can monitor the adsorption status of the component in real time (such as vacuum leakage or component displacement) and adjust the movement of the robotic arm through signal feedback to avoid misjudgment caused by component position deviation during the test.

[0040] A pusher cylinder mounting groove 18 is provided at the bottom of the lower mounting base 17 outside the nozzle mounting groove 22. A pusher cylinder 19 is installed in the pusher cylinder mounting groove 18. The pusher cylinder 19 drives the pusher block 21 to move up and down and freely pass through the pusher through hole 20 below.

[0041] At least two pusher cylinders 19 are symmetrically distributed on both sides of the lower mounting base 17 and move synchronously through pusher blocks 21. For example, after the test is completed, pusher blocks 21 can push the component from the test module 6 to the slide rail stage 4 with a pusher accuracy of ±0.05mm.

[0042] The pusher cylinder 19 has a stroke of 5-10mm and a speed controlled at 50-100mm / s to ensure smooth component delivery. For example, for a 0.5mm thick chip, the contact force of the pusher block 21 needs to be controlled at 0.5-1N to prevent component breakage.

[0043] At least two pusher cylinders 19 achieve precise unloading of components through pusher blocks 21. For example, after the test is completed, pusher blocks 21 can push the component from the test module 6 to the slide rail platform 4 to ensure the component position accuracy.

[0044] The second embodiment of this utility model: like Figure 4 As shown, in this embodiment, both the loading / unloading robotic arm 3 and the picking / placing robotic arm 5 have gripping components mounted on their bottoms via mounting brackets 8. These gripping components, from top to bottom, include an upper mounting base 12 and a lower mounting base 17. The upper mounting base 12 and the lower mounting base 17 are movably connected together via a connecting rod 16. A spring 27 is mounted on the connecting rod 16 between the upper mounting base 12 and the lower mounting base 17. The connecting rod 16 has a guide rod structure; its bottom is fixedly mounted on the lower mounting base 17, and its top is mounted on the upper mounting base 12 via a guide bearing.

[0045] Spring 27 is sleeved on connecting rod 16, located between upper mounting base 12 and lower mounting base 17, and fixed by limiting boss or retaining ring to ensure that the spring does not shift axially when compressed. The spring constant is 5-15 N / mm to accommodate the cushioning requirements of components of different weights. For example, a 5 N / mm spring provides sufficient cushioning for small components weighing 0.1-1g; a 15 N / mm spring is more suitable for medium-sized components weighing 1-5g.

[0046] The upper and lower mounting bases are movably connected by spring 27, which can absorb the inertial impact during the movement of the robotic arm, especially in high-speed transfer or emergency stop scenarios, significantly reducing the risk of component damage. For example, when the robotic arm quickly approaches the feed tray, the spring can offset some of the kinetic energy through its compression stroke, preventing the nozzle from directly colliding with the components.

[0047] Pads 26 and 23 are installed at the bottom of the lower mounting base 17 outside the pusher through hole 20 and at the bottom of the pusher block 21. The pads 26 are rubber pads or silicone pads. They can buffer the direct contact between the component and the metal part. For example, for glass-encapsulated electronic components, the pads can reduce the contact stress to below 0.1 MPa.

[0048] The pad 23 can be made of silicone rubber or fluororubber with a Shore hardness of 60-70 and a thickness of 2-3mm. The surface can be designed with wavy or grid patterns to increase the contact area with the component.

[0049] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
