[0013] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.
[0014] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component 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.
[0015] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
[0016] To solve the above technical problems, such as Figure 1-3 As shown, this utility model designs a conveying device for chip testing, including a first conveying line 1, a second conveying line 2, and a clamping and transferring mechanism. The first conveying line 1 and the second conveying line 2 are arranged side by side but in opposite directions. The height of the first conveying line 1 is higher than that of the second conveying line 2. The first conveying line is used to feed the cassette containing the chip to be tested, while the second conveying line is used to reverse the output to achieve a reversal. The clamping and transferring mechanism is used to transfer the cassette from the first conveying line 1 to the second conveying line 2. The clamping and transferring mechanism is fixed on the base 17 by a support mechanism and is located at the transmission end of the first conveying line 1 and the transmission beginning of the second conveying line 2.
[0017] The clamping and transfer mechanism includes a support plate 3, positioning rods 4, and a linear displacement assembly. The rear side of the support plate 3 is connected to a support mechanism. Positioning rods 4 are respectively located at the four corners of the front side of the support plate 3. The positioning rods 4 are perpendicular to the support plate 3 and their ends are connected to a guide plate 5. The guide plate 5 has a guide groove 6, the rear section of which is inclined downwards. The linear displacement assembly is installed on the front side of the support plate 3 and has a movable plate 7 that can move laterally. The front side of the movable plate 7 is fixedly connected to a mounting plate 8. The front side of the mounting plate 8 has a vertically arranged first guide rail 9, which is connected to a first slider 10. The front side of the first slider 10 is connected to a support plate 11. A limiting seat 12 is located above the support plate 11, and a roller 13 is located on the front side of the limiting seat 12. The roller 13 cooperates with the guide groove 6 of the guide plate 5 and can roll inside it. A clamping cylinder 14 is located below the support plate 11. The clamping cylinder 14 has two clamping blocks that can move closer or further apart simultaneously.
[0018] The linear displacement component first drives the moving plate 7 to move laterally. The roller 13 maintains a constant height while rolling in the front horizontal groove. After entering the rear inclined groove, the roller 13 is pressed down by the groove wall, which drives the support plate 11 to move vertically downward along the first guide rail 9. The clamping cylinder 14 clamps the material box simultaneously to complete the translation and height conversion. After reaching the position, it reverses and resets, realizing continuous transfer between two reverse conveying lines. This clamping and transfer mechanism completes the horizontal conveying and height difference adjustment of the material box in one go through the compound motion principle of lateral movement and guide groove 6. It eliminates the independent lifting link required by traditional devices. The overall structure is compact, the action is smooth, and the operation is stable without impact. At the same time, the rigid cooperation and synchronous clamping of the roller 13 and guide groove 6 ensure that the material box is accurately positioned and does not shake during the entire transfer process, which significantly improves the safety and cycle efficiency of chip detection and transfer.
[0019] In this embodiment, it is further preferred that the support mechanism includes a support rod 15 and a positioning seat 16. The two positioning seats 16 are symmetrically arranged on the base 17. The bottom end of the support rod 15 is inserted into the inner hole of the positioning seat 16, and the top end of the support rod 15 is fixedly connected to the support plate 3 through a connecting block to form a rigid column that can be quickly inserted and removed, ensuring the overall stability of the clamping and transfer mechanism during high-speed operation.
[0020] In this embodiment, it is further preferred that the support mechanism also includes a pipe clamp 18 and a baffle 19. The baffle 19 is U-shaped, and its two ends are respectively fixedly connected to a pipe clamp 18. The pipe clamp 18 is sleeved on the support rod 15. The baffle 19 is used to limit the material box in the front and back upward. The height of the pipe clamp 18 can be steplessly adjusted on the rod, so that the position of the baffle 19 can be easily adjusted up and down to adapt to different conveyor line positions.
[0021] In this embodiment, it is further preferred that the first conveyor line 1 and the second conveyor line 2 are both belt conveyors. Side plates 20 are symmetrically arranged on the left and right sides of the conveying path of each belt conveyor. The top of the side plate 20 is provided with a limiting pressure plate 21, which covers and closes the guide channel. When the material box is conveyed forward by the belt, the left and right side plates prevent lateral deviation, and the top pressure plate suppresses jumping and edge warping.
[0022] In a further preferred embodiment, the linear displacement assembly includes a lead screw 22, a movable block 23, a second guide rail 24, and a second slider 25. The lead screw 22 is arranged laterally and located on the front side of the support plate 3. One end of the lead screw 22 is used to connect with a motor. The movable block 23 is connected to the lead screw 22 via a lead screw nut, and one side of the movable block 23 is fixedly connected to the moving plate 7. The second guide rail 24 is arranged parallel to the lead screw 22 and fixed on the front side of the support plate 3. The second slider 25 is slidably connected to the second guide rail 24. The two sliders 25 are fixedly connected to the moving plate 7. The lead screw 22, the movable block 23, the second guide rail 24 and the second slider 25 together form a high-precision linear module. When the motor drives the lead screw 22 to rotate, the lead screw 22 nut directly converts the rotational motion into the high-rigidity linear displacement of the movable block 23. Combined with the synchronous sliding of the second slider 25 on the second guide rail 24, the entire moving plate 7 performs a high-precision and high-stability lateral reciprocating motion, which provides a reliable guarantee for the clamping and transfer mechanism to achieve fast, accurate and backlash-free material box transfer between two reverse conveyor lines.
[0023] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
