Description

Technical Field

[0001] This application relates to the field of transfer technology, specifically to a drawer transfer mechanism and a drawer conveying device. Background Technology

[0002] Testing technology for packaged chips has also become a crucial technology in the electronics industry for ensuring product quality and accelerating production processes.

[0003] The existing announcement number CN217497795U, entitled "Feeding and Receiving Equipment for Trays," relates to the technical field of electronic device manufacturing. This feeding and receiving equipment for trays includes a tray, a lifting mechanism, a tray conveying mechanism, and a first pushing mechanism. The tray includes multiple storage positions spaced at intervals and capable of sliding with the tray. The lifting mechanism is drivenly connected to the tray. The tray conveying mechanism is located on one side of the tray and has at least one feeding and receiving position along its conveying path, adjacent to a storage position at a preset height. The first pushing mechanism is located on one side of the tray conveying mechanism. This alleviates the technical problem in existing technologies where receiving stations are generally arranged parallel to the rear end of the equipment. Adding more receiving stations inevitably increases the space occupied by the equipment, resulting in an excessively large size. This achieves the technical effect of meeting multiple batching requirements in a small space, relatively reducing the space occupied by the equipment, and thus reducing its size.

[0004] Although existing tray feeding and receiving equipment has solved the problem of transferring trays between the tray conveying mechanism and the cassette, in order to improve the level of automation, the inspected trays or the trays to be inspected also need to be automatically sent out of or into the cassette.

[0049] The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0050] In some embodiments of this application, reference is made to Figure 1 , 2 As shown, this application provides a drawer transfer line, including: at least two gripping mechanisms, a drawer transfer mechanism, and a drawer 12. The drawer transfer mechanism includes: a drawer box 10, a platform 20, and a drive unit 30. The drawer box 10 is used to house the drawer 12; that is, the drawer box 10 is mounted on the platform 20, and the drawer 12 is loaded inside the drawer box 10. The drawer 12 is used to carry workpieces; in this embodiment, the workpiece is a fixture for loading chips. The platform 20 is provided with a rotary driver 22, and the drawer box 10 is connected to the rotary driver 22. Driven by the rotary driver 22, the drawer box 10 rotates relative to the platform 20 around its own central axis. At least two gripping mechanisms are distributed on the circumferential outer side of the drawer box 10. The drawer 12 inside the drawer box 10 can be rotated to gripping mechanisms in different directions, so that gripping mechanisms in different directions can remove the drawer 12 from the drawer box 10 or send the drawer 12 into the drawer box 10. The stage 20 cooperates with the drive unit 30. Specifically, the stage 20 includes a base plate 21, a rotary driver 22 mounted on the base plate 21, and the base plate 21 also supports the drawer box 10. The base plate 21 is mounted on the power output end of the drive unit 30. Driven by the drive unit 30, the stage 20 and the drawer box 10 move along a vertical straight line (i.e., the Z-axis shown in the figure).

[0051] Combination Figure 4-6 As shown, the drawer box 10 includes a box body 11, which has a receiving cavity 111 for accommodating a plurality of drawers 12. A plurality of sliding frames 13 for storing the drawers 12 are slidably connected inside the box body 11, and the sliding frames 13 are arranged vertically within the box body 11, extending from one side of the box body 11. Specifically, the sliding frame 13 accommodates the drawers 12 by including a side panel 131. One side of the side panel 131 is connected to the inner wall of the box body 11 via a guide unit, allowing the sliding frame 13 to move relative to the box body 11. The guide unit can be a matching slider and a slide rail, with the slider and slide rail cooperating to allow the sliding frame 13 to slide relative to the box body 11. The other side of the side panel 131 is provided with a slide rail 134 that cooperates with the drawers 12. The drawers 12 are provided with a sliding block 123, and the slide rail 134 and sliding block 123 cooperate to achieve a slidable connection between the drawers 12 and the sliding frame 13. The sliding frame 13 is surrounded by the side panel 131 and the top panel to form a accommodating space. The drawer 12 is placed in the accommodating space, and the slide rail 134 is set in the accommodating space. The drawer 12 is supported in the accommodating space by the slide rail 134 and the slide block 123.

[0052] The rotary actuator 22 drives the drawer box 10 to rotate to either the first or second working position, that is, the drawer box 10 switches between the first and second working positions. Specifically, refer to... Figure 1 As shown, when the drawer box 10 is in the first working position, the sliding frame 13 extends towards the front of the platform 20. (Reference) Figure 2 As shown, when the drawer box 10 is in the second working position, the sliding frame 13 extends towards the opposite side of the platform 20. The drawer box 10 rotates 180° from the first working position to the second working position, that is, the sliding frame 13 extends towards the back side of the platform 20. Specifically, the front and back sides of the platform 20 are the opposite sides of the platform 20 and are adjacent to the sides of the connecting drive unit 30. In this solution, the rotary driver 22 drives the drawer box 10 to rotate 180°, enabling the drawer box 10 to retrieve and place the drawer 12 in at least two working positions.

[0053] The two gripping mechanisms correspond to the first and second workstations, respectively. Specifically, one gripping mechanism is set up for the first workstation, and the other gripping mechanism is set up for the second workstation. (Refer to...) Figure 3 As shown, drawer 12 is equipped with a gripping block 122 that cooperates with the gripping mechanism. Taking the gripping of drawer 12 inside drawer box 10 as an example, when drawer box 10 rotates to the first working position, the gripping block 122 of drawer 12 inside drawer box 10 faces one of the gripping mechanisms. This gripping mechanism, by cooperating with the gripping block 122, pulls drawer 12 out of drawer box 10. When drawer box 10 rotates to the second working position, the gripping block 122 of drawer 12 inside drawer box 10 faces another gripping mechanism. This gripping mechanism, by cooperating with the gripping block 122, pulls drawer 12 out of drawer box 10. Similar to gripping drawer 12 inside drawer box 10, to store drawer 12 into drawer box 10, drawer box 10 first rotates to face the corresponding gripping mechanism. After the gripping mechanism grabs drawer box 10 and delivers it into drawer box 10, the gripping mechanism separates from the gripping block 122 to complete the storage of drawer 12.

[0054] Furthermore, the sliding frame 13 is connected to the housing 11 via a cylinder 14. The cylinder 14 automatically drives the sliding frame 13 to slide relative to the housing 11, allowing the sliding frame 13 to extend or retract from one side of the housing 11 into the housing 11. Driven by the cylinder 14, the sliding frame 13 approaches the corresponding gripping mechanism. The sliding frame 13 can then move the drawer 12 closer to the gripping mechanism. After the gripping mechanism engages with the gripping block 122, the sliding frame 13 retracts into the housing 11, causing the housing 11 to move relative to the drawer 12, thus separating the drawer 12 from the sliding frame 13 and allowing the drawer 12 to be removed from the housing 11. Similar to grabbing the drawer 12 inside the drawer box 10, the empty sliding frame 13 approaches the corresponding grabbing mechanism. The sliding frame 13 moves relative to the drawer 12 on the grabbing mechanism, and the drawer 12 extends into the sliding frame 13. After the drawer 12 is inserted into the sliding frame 13, the grabbing mechanism separates from the grabbing block 122. Driven by the cylinder 14, the sliding frame 13 drives the drawer 12 to retract into the box 11.

[0055] Meanwhile, since the sliding frame 13 is arranged in the box 11 along the vertical Z-axis, in order to ensure that the gripping mechanism can pick up and put down the drawers 12 at different heights in the box 11, the drive unit 30 drives the box 11 to reciprocate along the Z-axis, so that the sliding frame 13 at different heights corresponds to the gripping mechanism, that is, the sliding frame 13 at different heights is flush with the gripping mechanism.

[0056] In some embodiments of this application, such as Figure 4 As shown, the receiving cavity 111 extends to the two opposite sides of the housing 11 to form openings. The sliding frame 13 extends from one side of the housing 11, specifically, the sliding frame 13 can extend outward from the opening on one side of the housing 11. A stop block 114 is provided on the other side of the housing 11 opposite to the sliding frame 13, and the stop block 114 extends into the corresponding opening. The stop block 114 prevents the sliding frame 13 from coming out of the opening, so that the sliding frame 13 can only extend from one side of the opening, thereby limiting the extension direction of the sliding frame 13. More specifically, a positioning detector can also be installed on the stop block 114. When the sliding frame 13 approaches the positioning detector or directly contacts the positioning detector, it is determined that the sliding frame 13 has been properly housed in the housing 11.

[0057] Furthermore, such as Figure 5 , 6As shown, the side panel 131 is also provided with an outwardly extending bracket 132, which is specifically a protrusion extending outward toward the box body 11. To avoid interference, a clearance groove 115 is provided on the box body 11 at the position corresponding to the bracket 132. The bracket 132 extends out of the clearance groove 115 and can move within the clearance groove 115. The guide unit and the bracket 132 support the weight of the sliding frame 13 and the drawer 12 housed in the sliding frame 13. At the same time, the terminating end of the clearance groove 115 can also block the movement of the bracket 132, thereby limiting the sliding distance of the sliding frame 13.

[0058] Furthermore, such as Figure 3 As shown, drawer 12 includes a cover plate 121, and a gripping block 122 is disposed on the cover plate 121. The area of ​​the cover plate 121 is larger than the area of ​​the entrance of the sliding frame 13. When drawer 12 is stored in the sliding frame 13, the cover plate 121 is exposed outside the sliding frame 13, and the cover plate 121 is closer to the gripping mechanism. Furthermore, the cover plate 121 can cover the sliding frame 13 to block the entrance of the sliding frame 13, effectively preventing outside air from entering the sliding frame 13 and thus avoiding the risk of impurities contaminating the chips loaded inside drawer 12.

[0059] A clamping module 135 is also installed on the side plate 131, with the clamping module 135 located on one end of the side plate 131 extending out of the housing 11. After the drawer 12 and the sliding frame 13 are installed in place, the clamping module 135 engages with the end face of the side plate 131 to clamp the cover plate 121, preventing the drawer 12 from moving relative to the sliding frame 13 due to centrifugal force during the rotation of the housing 10. Specifically, the clamping module 135 includes a drive unit 1351 and a clamping block 1352. The clamping block 1352 is connected to the power output end of the drive unit 1351, which can extend, retract, and rotate, allowing the clamping block 1352 to rotate to be positioned on or away from the sliding path of the cover plate 121 in the sliding frame 13, and the clamping block 1352 can move toward the end face of the side plate 131. When the drawer 12 is inserted into the sliding frame 13, the clamping block 1352 is moved away from the sliding path of the drawer 12 in the sliding frame 13 to prevent the clamping block 1352 from interfering with the cover plate 121. After the drawer 12 and the sliding frame 13 are installed in place, the drive unit 1351 first drives the clamping block 1352 to rotate so that it is on the sliding path of the cover plate 121 in the sliding frame 13, and then drives the clamping block 1352 to move toward the end face of the side plate 131 to clamp the cover plate 121.

[0060] In this design, the installation of drawer 12 and sliding frame 13 into place is detected by positioning detector 136, which controls the operation of drive unit 1351 and cylinder 14. More specifically, a fixing block 133 is installed at one end of side plate 131 where clamping module 135 is installed. The fixing block 133 and clamping module 135 are respectively located on both sides of side plate 131. Position detector 136 is installed on fixing block 133. When drawer 12 is inserted into sliding frame 13, cover plate 121 approaches positioning detector 136 and is eventually sensed by positioning detector 136. At this point, it is determined that drawer 12 and sliding frame 13 are installed in place.

[0061] In some embodiments of this application, the drawer box 10 is rotatably connected to the platform 20, and the drawer box 10 is drive-connected to the rotary drive 22. In this embodiment, the drawer box 10 and the rotary drive 22 are driven by gear meshing.

[0062] However, it is understood that the rotary actuator 22 can drive the drawer box 10 to rotate via gear meshing, but is not limited to this. The drawer box 10 can also be directly mounted on the rotating shaft of the rotary actuator 22. Belt drive is also an option. Therefore, common transmission methods by which the rotary actuator 22 drives the components to rotate should be considered specific embodiments of this application.

[0063] In this preferred embodiment, the drawer box 10 and the rotary drive 22 are driven by gear meshing, specifically, as follows: Figure 4 As shown, the drawer box 10 is supported on the base plate 21, and the rotary drive 22 is mounted on the base plate 21. A driven gear 113 is fixedly connected to the bottom plate 112 of the box body 11, and a bearing seat 211 adapted to the shaft hole of the driven gear 113 is provided on the platform 20. A driving gear 222 that meshes with the driven gear 113 is installed on the power output end of the rotary drive 22.

[0064] Furthermore, the pitch circle of the driving gear 222 is smaller than that of the driven gear 113. In this design, the number of teeth of the driving gear 222 is less than that of the driven gear 113. The large and small gears are used to reduce speed and increase torque. The small-power rotary drive 22 drives the heavy drawer box 10, thus reducing the size of the rotary drive 22.

[0065] It should be noted that the driven gear 113 can be a full gear or a half gear. Depending on the rotation angle of the drawer box 10, the teeth on the half gear mesh with the teeth of the driving gear 222, and the rotary drive 22 rotates back and forth, causing the drawer box 10 to rotate 180°.

[0066] The above embodiments are used to further illustrate this application, but do not limit this application to these specific implementations. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be understood as falling within the protection scope of this application.
