[0015] This invention provides multi-directional support by using at least two supporting cylinders to drive the support plate through a linkage rod, which significantly improves the stability of electronic components during transfer.

[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.

[0022] The specific embodiments of this utility model will be described in further 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 its scope.

[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, an electronic component transfer testing device according to this embodiment includes a working platform 1, on which a feeding tray 2, a loading / 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 installed.

[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 picking / placing robotic arm 5 in the prior art have a gripping component mounted on the bottom via a mounting bracket 8. This gripping component is a vacuum suction cup 9, which is used to grip and process electronic 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] A support cylinder mounting groove 18 is provided on the side of the lower mounting base 17 to accommodate the support cylinder 19. The support cylinder 19 drives the outer linkage rod 20 to move in the inward and outward directions. A support plate 21 is installed on the inner side of the bottom of the linkage rod 20. There are at least two support cylinders 19.

[0036] At least two supporting cylinders 19 synchronously drive the support plate 21 via a linkage 20, forming a symmetrical support structure. For example, when gripping a square component, the support plate 21 applies force evenly from both sides to prevent the component from tilting or slipping due to force on one side.

[0037] In addition, pads 23 are installed on the lower mounting base 17 on the outer side of the bottom of the nozzle mounting groove 22 and on the tray 21. The pads 23 are rubber pads or silicone pads. The pads 23 on the bottom of the nozzle mounting groove and the surface of the tray 21 can buffer the direct contact between the component and the metal parts and avoid scratching the surface of the component. For example, for glass-encapsulated electronic components, the rubber pads can reduce the contact stress to below 0.1 MPa.

[0038] 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 24 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.

[0039] Spring 24 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.

[0040] The upper and lower mounting bases are movably connected by spring 24, 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 suction nozzle from directly colliding with the components.

[0041] A suction nozzle 13 is installed at the bottom center of the upper mounting base 12. A vacuum connector 14, which communicates with the adsorption chamber inside the suction nozzle 13, is installed on the top of the upper mounting base 12 above the suction nozzle 13. The vacuum connector 14 is detachably installed on the upper mounting base 12, and an air pipe 15 with a connecting hose structure is installed on the vacuum connector 14.

[0042] The vacuum connector 14 and the upper mounting base 12 are connected by threads (M5×0.8 specification), and an O-ring is provided at the thread to prevent air leakage. Disassembly can be performed simply by rotating the connector, without tools.

[0043] 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.

[0044] A support cylinder mounting groove 18 is provided on the side of the lower mounting base 17 to accommodate the support cylinder 19. The support cylinder 19 drives the outer linkage rod 20 to move in the inward and outward directions. A support plate 21 is installed on the inner side of the bottom of the linkage rod 20. There are at least two support cylinders 19. The stroke of the support cylinder 19 is 5-10mm to cover the thickness range of common electronic components.

[0045] A sealing ring (such as made of fluororubber) is installed between the nozzle 13 and the nozzle mounting groove 22 to effectively isolate the vacuum chamber from the external environment and ensure stable adsorption force. The sealing ring is embedded in the annular groove of the nozzle mounting groove 22, with a groove depth of 80% of the sealing ring thickness, ensuring that the sealing ring retains its elasticity under compression and preventing failure due to excessive compression. The fluororubber sealing ring has better corrosion resistance and high temperature resistance than ordinary rubber, and can adapt to working environments from -20℃ to 200℃, meeting the high-temperature requirements of electronic component testing.

[0046] In addition, pads 23 are installed on the lower mounting base 17 on the outer side of the bottom of the nozzle mounting groove 22 and on the tray 21. The pads 23 are rubber pads or silicone pads.

[0047] The spacers are secured to the lower mounting base and tray surface using adhesive backing or countersunk screws, ensuring they do not detach during long-term use. Spacers 23 can be designed in a corrugated or mesh pattern to increase the contact area with the component and further distribute stress. For example, a corrugated spacer can increase the contact area by 30%, reducing localized pressure.

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.

[0049] 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.
