Description

Technical Field

[0001] The utility model relates to the technical field of chip transportation tooling, and particularly relates to a chip loading and unloading bin. Background Art

[0002] A chip includes a substrate, a semi-finished chip, and a finished chip welded by the two. Among them, the loading and unloading bin is used to store a tray, and the tray can store a substrate or a finished chip. The loading and unloading bin includes two storage areas, namely a to-be-mounted substrate loading area and an empty substrate tray unloading area, so as to realize the loading of the substrate and the unloading of the substrate tray. The two storage areas can also be set as an empty finished chip tray loading area and a full finished chip unloading area, so as to realize the loading of the finished chip tray and the unloading of the finished chip. The same applies to the two storage areas of the semi-finished chip.

[0003] The patent with the publication number of CN218260741U discloses a loading and unloading mechanism for a chip cartridge. The loading and unloading mechanism includes a support frame, a pair of clamping mechanisms, and a transfer mechanism. The clamping mechanisms are arranged on the support frame; the pair of clamping mechanisms can clamp a plurality of chip cartridges stacked vertically; the transfer mechanism includes a horizontal transfer mechanism and a secondary lifting mechanism; the secondary lifting mechanism is arranged on the horizontal transfer mechanism; the first lifting of the secondary lifting mechanism can support the chip cartridges in the chip cartridge storage area; the second lifting can drive the chip cartridges in the chip cartridge storage area to lift synchronously. Through the cooperation drive of the clamping mechanism and the transfer mechanism, this patent can load and unload the stacked chip cartridges. The transfer mechanism transfers inside the support frame, occupying less space, so that it can be applicable to small-space places and has a wide range of application places.

[0004] However, the secondary lifting mechanism of this patent needs to be driven by two corresponding lifting cylinders, and the equipment structure is relatively complex, and the setting cost is relatively high. Secondly, the secondary lifting mechanism is fixed on the side of the horizontal transfer mechanism, generally fixed by screws. Since the vibration driven by the cylinder is relatively large, the screws are prone to loosen or break under long-term operation, and the installation structure stability of the secondary lifting mechanism is relatively poor, resulting in a reduction in the installation accuracy of the cylinder on the horizontal transfer mechanism, and further reducing the picking accuracy and welding accuracy of the workpiece, affecting the quality of the finished chip.

[0045] See Figures 1 to 4, the present utility model provides a chip loading and unloading bin, and the chip loading and unloading bin includes a rack 1, a transfer mechanism 2 and a lifting mechanism 3; the transfer mechanism 2 passes through the inside of the rack 1; the transfer mechanism 2 includes a linear guide rail 21 and a slide plate 22; the slide plate 22 is slidably connected to the linear guide rail 21 longitudinally; the slide plate 22 is provided with an extension plate 221 extending transversely out of the linear guide rail 21; the lifting mechanism 3 includes a lifting driver 31, a guiding component 32 and a supporting frame 33; the lifting driver 31 is installed at the bottom end of the extension plate 221; the guiding component 32 is installed at the top end of the extension plate 221; the transmission shaft of the lifting driver 31 penetrates through the extension plate 221 and is vertically connected to the supporting frame 33 in a transmission manner; the supporting frame 33 is slidably connected to the guiding component 32.

[0046] Taking Figure 3 the shown orientation as an example, the left - right direction is the transverse direction, the up - down direction is the vertical direction, and the direction perpendicular to the transverse and vertical directions is the longitudinal direction. The extension plate 221 and the slide plate 22 are preferably integrally arranged. As for the loading and unloading method of the chip loading and unloading bin, reference can be made to the technical solution disclosed in the patent CN218260741U, and the present utility model will not elaborate further.

[0047] The slide plate 22 is provided with an extension plate 221 extending transversely out of the linear guide rail 21, and then the lifting driver 31 is installed at the bottom end of the extension plate 221, realizing the installation of the lifting mechanism 3 on the side of the slide plate 22. This effectively avoids the situation where the lifting driver 31 is directly installed at the top end of the slide plate 22, causing the acting force to directly act on the transmission shaft. Thus, forces such as the pressure of multiple trays and the reaction force received by the lifting driver 31 can be concentrated on the linear guide rail 21, which not only extends the service life of the equipment but also improves the positioning accuracy of the supporting frame 33 during long - term operation, and further improves the welding quality of the finished chips.

[0048] The guiding component 32 is installed at the top end of the extension plate 221 to guide the vertical lifting of the supporting frame 33, improving the stability and accuracy of the supporting frame 33 during vertical lifting. The lifting driver 31, the guiding component 32 and the supporting frame 33 are arranged vertically, enabling the acting force to be stably applied to the extension plate 221, and then transferring the acting force to the linear guide rail 21, improving the reliability of the loading and unloading accuracy of the equipment. The extension plate 221 can effectively support the lifting mechanism 3. Therefore, only one lifting mechanism can be used to realize the loading and unloading of the tray 6, that is, there is no need to add an additional lifting mechanism to support the loading and unloading process of the lifting mechanism 3, simplifying the equipment structure and reducing the equipment cost.

[0049] Furthermore, the guiding component 32 includes a top plate 321 and guiding columns 322; one end of each guiding column 322 is connected to the extension plate 221, and the other end is connected to the top plate 321; the top support frame 33 is slidably connected to the guiding columns 322 in the vertical direction; a sleeve 331 is provided on the top support frame 33; internal threads are provided inside the sleeve 331; the transmission shaft of the lifting driver 31 is a lead screw; the lead screw is threadedly connected to the sleeve 331. In this embodiment, the lifting mechanism 3 is a motor lead screw slider module, adopting a transmission method of threaded connection. The vertical lifting of the top support frame 33 is guided by the guiding columns 322, and the top plate 321 and the extension plate 221 can limit the vertical lifting stroke of the top support frame 33 to prevent the top support frame 33 from disengaging from the guiding columns 322. Specifically, the lifting driver 31 is a motor or a motor, and the transmission shaft of the lifting driver 31 can rotate forward and backward. When the transmission shaft rotates, the sleeve 331 rises or falls in the vertical direction, thereby driving the top support frame 33 to rise or fall, and cooperating with the clamping mechanism 5 installed on the rack 1 to load or unload the tray 6. The transmission structure is simple, practical, has strong transmission stability, and a long service life.

[0050] Secondly, the lead screw is rotatably connected to the top plate 321 to improve the positioning accuracy of the transmission shaft and further improve the transmission stability of the equipment. Optionally, a linear bearing 34 is provided on the top support frame 33; the linear bearing 34 is slidably connected to the guiding columns 322 in the vertical direction. Crossed roller bearings are provided inside the top plate 321 and the extension plate 221, and the crossed roller bearings are sleeved on the transmission shaft to further improve the transmission stability and accuracy of the equipment.

[0051] In other embodiments, the lifting driver 31 is a cylinder, a hydraulic cylinder or an electric push rod; the guiding columns 322 are slidably connected to the extension plate 221 in the vertical direction; the top plate 321 is fixedly connected to the guiding columns 322, and the top plate 321 abuts against the transmission shaft; the top support frame 33 is fixedly connected to the guiding columns 322. Specifically, when the transmission shaft expands and contracts, the top plate 321 and the guiding columns 322 are synchronously lifted or lowered, thereby driving the top support frame 33 to be synchronously lifted or lowered. This embodiment can also achieve stable transmission and high-precision positioning during the loading and unloading process of the lifting mechanism.

[0052] In addition, the linear bearing 34 and / or the sleeve 331 can abut against the top plate 321 or the extension plate 221 to limit the vertical lifting stroke of the top support frame 33 through the linear bearing 34 and / or the sleeve 331. Optionally, buffer pads are provided on the top plate 321 and the extension plate 221 to buffer the collision force between the linear bearing 34 and the sleeve 331 and the top plate 321 and the extension plate 221 respectively, thereby reducing the vibration received by the workpieces in the tray 6 and ensuring the placement accuracy of the workpieces in the tray 6 during transportation.

[0053] Furthermore, the chip loading and unloading bin further includes a drag chain 4; the drag chain 4 is connected to the bottom end of the expansion board 221; and the lifting driver 31 is arranged between the linear guide rail 21 and the drag chain 4. The drag chain 4 can improve the force balance of the equipment, the linear guide rail 21 and the drag chain 4 form a supporting structure on both sides of the lifting driver 31, and the drag chain 4 can effectively share the force on the linear guide rail 21, further extending the service life of the equipment and the transmission stability.

[0054] Secondly, the top support frame 33 includes a frame body 332 and a material picking plate 333; the guide assembly 32 is vertically slidably connected to the middle of the bottom plate of the frame body 332; the material picking plate 333 is arranged at the top of the frame body 332. The frame body 332 and the material rack 1 are both frame structures. The advantage of the frame structure is that tooling can be installed inside it to reduce the space occupied by the chip loading and unloading bin. The guide assembly 32 can be vertically lifted and lowered in the middle of the inner side of the frame body 332. On the one hand, the center of gravity of the top support frame 33 falls on the transmission shaft, that is, the expansion plate 221, which improves the horizontality of the top surface of the material picking plate 333 during the transmission process; on the other hand, the center of gravity falls on the expansion plate 221, which is convenient for the linear guide rail 21 and the drag chain 4 to effectively support and improve the reliability of equipment transportation.

[0055] In the first embodiment, a plurality of pairs of elastic buckles 3331 are provided on the material taking plate 333; a pair of elastic buckles 3331 can move closer to or farther from each other in the horizontal or vertical direction. Specifically, a chamfer is provided at the top of the elastic buckle 3331, and when the elastic buckle 3331 abuts against the material tray, the material tray 6 can push the elastic buckle 3331 to slide toward the side away from the center of the material tray 6 until the material tray 6 is clamped into the inner side of the elastic buckle 3331, and the elastic buckle 3331 rebounds and resets to achieve the clamping of the material tray 6. When the material taking plate 333 needs to remove the material tray 6, the plurality of material trays 6 stacked on the material rack 1 are pressed against the material tray 6 that has been clamped by the material taking plate 333, and the material tray 6 at the bottom of the plurality of stacked material trays 6 can open the plurality of elastic buckles 3331, and the material tray 6 in the material taking plate 333 can be taken out by cooperating with the clamping mechanism 5. The multiple pairs of elastic buckles 3331 are purely mechanical structures, do not require external power drive, have a simple and practical structure, and effectively improve the transportation stability of the material tray 6.

[0056] In the second embodiment, a suction hole is provided at the top of the material taking plate 333. The suction hole is connected to an air pipe, and the material tray 6 is taken and placed by vacuum adsorption. The structure is simple and practical, and the material tray 6 can also be transported stably and quickly taken and placed.

[0057] Further, the transfer mechanism 2 and the lifting mechanism 3 are arranged mirror-symmetrically in the rack 1. Mirror symmetry includes symmetric arrangement and replication and translation in the horizontal direction. One transfer mechanism 2 and one lifting mechanism 3 form a set of loading and unloading tooling. In this embodiment, replication and translation in the horizontal direction are adopted, that is, two sets of loading and unloading tooling are arranged horizontally inside the rack 1. The loading and unloading structures and principles of the two are the same. The difference is that one set of loading and unloading tooling is used for loading and unloading the substrate, and the other set of loading and unloading tooling is used for loading and unloading the finished chips, realizing the high integration of the loading and unloading tooling for the substrate and the loading and unloading tooling for the finished chips. Compared with the existing integrated loading and unloading tooling, the two sets of loading and unloading tooling of the chip loading and unloading bin of the present utility model operate independently, and there is no idling of the loading and unloading tooling during the operation process, effectively shortening the loading and unloading time of the workpiece. The lifting mechanism 3 is driven by a single driver, reducing the equipment cost. The method of arranging the lifting mechanism 3 on the side of the transfer mechanism 2 effectively reduces the stress on the transmission shaft, improves the picking and placing accuracy and transportation accuracy of the lifting mechanism 3 for the tray 6, and finally improves the welding quality of the finished chips.

[0058] It should be understood that the above description of the specific embodiments of the present utility model is only for explaining the technical route and features of the present utility model, and its purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly. However, the present utility model is not limited to the above specific embodiments. Any changes or modifications made within the scope of the claims of the present utility model should be covered by the protection scope of the present utility model.
