[0068] The linkage type pull-out bin provided in this embodiment, at the beginning, the linkage type positioning fixture 3 is located outside the workpiece suction and placement assembly 1, when the workpiece needs to be stored:

[0069] First, place the workpiece on the linkage positioning fixture 3, and the linkage positioning fixture 3 clamps and positions the workpiece;

[0070] Next, the fixture linear drive mechanism 4 transports the linkage positioning fixture 3 together with the workpiece to the bottom of the workpiece suction and placement assembly 1;

[0071] Then, the workpiece suction and placement assembly 1 sucks up the workpiece;

[0072] Subsequently, the fixture linear drive mechanism 4 drives the linkage positioning fixture 3 back to the outside of the workpiece suction and placement assembly 1; on the one hand, it avoids the workpiece storage, and on the other hand, it can continue to clamp and position the next workpiece;

[0073] Finally, the workpiece suction and placement assembly 1 places the workpiece on the lifting storage platform 2, and the lifting storage platform 2 descends one layer to wait for the next storage.

[0074] Therefore, the linkage-type drawer silo provided by the present invention can effectively solve the problem of low vertical alignment accuracy of workpieces in existing lifting silos.

[0075] See also Figure 3 In this embodiment, the linkage positioning fixture 3 includes a positioning base plate 301 , two positioning clamping plates 302 , and two driving slides 303 .

[0076] The two positioning clamps 302 are slidably arranged relative to the positioning base plate 301 along the X direction, and the ends of the two positioning clamps 302 close to each other are provided with clamp rollers 3021; ​​the ends of the two positioning clamps 302 away from each other are provided with U-shaped clamping parts 3022 for clamping and positioning the workpiece.

[0077] The two driving slides 303 are slidably arranged relative to the positioning base plate 301 along the Y direction, and the ends of the two driving slides 303 close to each other are provided with a guiding inclined groove 3031 for the clamping roller 3021 to extend into; wherein the X direction and the Y direction are perpendicular to each other, and each of the driving slides 303 is correspondingly provided with a slide spring for driving the corresponding driving slide 303 to slide away from the other driving slide 303.

[0078] The distance between the two guide inclined grooves 3031 on each driving slide 303 gradually increases in a direction away from the other driving slide 303, so that:

[0079] When the two driving slides 303 approach each other, the two U-shaped clamping portions 3022 move away from each other to release the workpiece;

[0080] When the two driving slides 303 move away from each other, the two U-shaped clamping portions 3022 move closer to each other to clamp and position the workpiece.

[0081] See also Figure 5 and Figure 6 The linkage positioning fixture 3 also includes a hook plate limiting member 304 , a rotating hook plate 305 , and a hook plate torsion spring 306 .

One end of the rotating hook plate 305 is rotatably connected to the driving slide 303, and the other end is provided with a hook portion for engaging with the hook plate stopper 304. The hook plate torsion spring 306 is used to drive the rotating hook plate 305 to rotate upward until it engages with the hook plate stopper 304, so as to limit the two driving slides 303 from sliding in a direction away from each other and maintain the clamping state of the workpiece.

[0083] See also Figure 4~Figure 6 The linkage pull-out silo also includes a discharge mechanism 6, which includes a lifting discharge frame 601, a discharge linear drive mechanism 602, and an unlocking pressure plate 603.

A positioning column 503 is provided at the top corner of the U-shaped storage rack 501; the driving end of the drawer linear drive mechanism 502 is connected to the U-shaped storage rack 501, and is used to drive the U-shaped storage rack 501 in and out from directly below the storage plate 201.

[0089] At the beginning, the position of the L-shaped discharge plate 6011 is higher than the positioning bottom plate 301, and the hook plate torsion spring 306 drives the rotating hook plate 305 to engage with the hook plate limiter 304, so that there is a large space between the two U-shaped clamping parts 3022 to facilitate the subsequent placement of workpieces; the linkage pull-out bin provided in this embodiment has the following working process:

[0090] (1) Workpiece placement and preliminary positioning:

[0091] The robot places the workpiece on the L-shaped unloading plate 6011;

[0092] Next, the discharge linear drive mechanism 602 drives the lifting discharge frame 601 to descend, and then places the workpiece on the positioning base plate 301;

[0093] The material discharge linear drive mechanism 602 drives the lifting material discharge frame 601 to continue to descend until the unlocking pressing plate 603 presses the hook portion downward to release the clamping state between the rotating hook plate 305 and the hook plate limiter 304;

[0094] Next, under the elastic force of the slide plate spring, the two driving slide plates 303 are driven to slide away from each other, and the clamping plate roller 3021 is guided by the guide inclined groove 3031, so that the two U-shaped clamping parts 3022 are brought close to each other to clamp and position the workpiece.

[0095] (2) Workpiece transportation and absorption:

[0096] The unloading mechanism 6 moves upward, on the one hand to avoid the lateral movement of the subsequent linkage positioning fixture 3, and on the other hand to receive the next workpiece;

[0101] (3) Workpiece release and fixture reset:

[0102] The suction and placement linear drive mechanism 103 is started, and the suction and placement frame 101 of the workpiece suction and placement assembly 1 rises to suck up the workpiece from the linkage positioning fixture 3 .

[0103] At the same time, the linkage positioning fixture 3 returns to the outside of the workpiece suction and placement assembly 1, ready to receive the next workpiece.

[0104] (4) Workpiece storage:

[0105] The workpiece suction and placement assembly 1 places the workpiece on the material storage plate 201 of the lifting material storage platform 2 .

[0106] The material storage linear drive mechanism 202 is started, and the material storage plate 201 descends one layer to complete the storage of the workpiece.

[0107] (5) Workpiece removal:

[0108] As the number of workpieces on the material storage plate 201 increases, the material storage plate 201 gradually descends. When the material storage plate 201 descends below the U-shaped material storage rack 501, the workpieces on the material storage plate 201 are transferred to the U-shaped material storage rack 501.

[0109] The drawer linear drive mechanism 502 is started to drive the U-shaped storage rack 501 to move outward, so that the workpiece can be sent outward, and the operator or the automated equipment can take the workpiece out of the U-shaped storage rack 501.
