[0037] To make the above - mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0038] This embodiment provides a tray transfer device, as shown in Figures 1 to 3As shown in the figure, the tray transfer device includes a base frame 100 and a conveying frame 200. The conveying frame 200 is reciprocally movable along the conveying direction and is arranged on the base frame 100. The conveying frame 200 includes two mounting plates 230 arranged at intervals along the conveying direction, and both of the two mounting plates 230 extend along a first horizontal direction perpendicular to the conveying direction; clamping mechanisms are arranged on both of the two mounting plates 230. The clamping mechanism includes a clamping driving member 310. The output end of the clamping driving member 310 is fixedly provided with a movable plate 320. The movable plate 320 is provided with clamping jaws 330 and a tray separating driving member 410. The output end of the tray separating driving member 410 is fixedly provided with a tray separating claw 420. The clamping driving member 310 is used to drive the movable plate 320 so that the clamping jaws 330 clamp the tray 800; the tray separating driving member 410 is used to drive the tray separating claw 420 to move downward after the clamping jaws 330 clamp the tray 800, so as to separate the clamped tray 800 and the adjacent tray below it.

[0039] For the tray transfer device provided in this embodiment, the transfer of the tray 800 and the feeding components 900 thereon is realized by moving the conveying frame 200 along the conveying direction. Moreover, a clamping mechanism for clamping the tray 800 and a tray separating mechanism for separating the clamped tray 800 and the tray below it are arranged on the conveying frame 200. During the working process, the clamping driving member 310 first drives the movable plate 320 so that the clamping jaws 330 clamp the uppermost tray 800 from the opposite sides. Then, the tray separating driving member 410 drives the tray separating claw 420 to move downward. At this time, if the clamped tray 800 has a problem of tray stacking, the tray separating claw 420 will apply a downward pressure to the tray located below the clamped tray 800, so as to separate it from the clamped tray 800. That is, for the tray transfer device provided in this embodiment, by arranging the tray separating mechanism, the problem of tray stacking during the feeding of the tray 800 can be effectively solved.

[0040] Moreover, in this embodiment, since the clamping driving member 310 can drive the movable plate 320 to move along the conveying direction, within the moving range of the clamping jaws 330, the tray transfer device provided in this embodiment can clamp, separate and transfer trays 800 with different sizes along the conveying direction, and has good compatibility with trays 800 with different size specifications along the conveying direction, so the applicable range is relatively large.

[0041] Specifically, in this embodiment, the clamping driving member 310 is a clamping cylinder, and the tray separating driving member 410 is a tray separating cylinder, and both are three-axis cylinders. Of course, in other embodiments of the present application, both of them can also be hydraulic cylinders or linear motors, etc.

[0042] Specifically, in this embodiment, there is a gap between two adjacent trays 800 above and below, and the end of the tray separating claw 420 can be inserted into the gap. In this setting, after the end of the tray separating claw 420 is inserted into the gap between two adjacent trays 800 above and below, the upper and lower trays 800 are separated in space. As long as a downward pressure greater than the adsorption force between them is applied, the two can be reliably separated. Of course, in other embodiments of the present application, the tray separating claw 420 may not be inserted into the gap between two adjacent trays 800 above and below. For example, the tray separating claw 420 can also drive the lower tray to move downward by adsorbing the tray below the clamped tray 800 to separate it from the clamped tray 800.

[0043] Specifically, in this embodiment, as Figure 4 and Figure 5 shown, a clamping surface 331 is provided at the end of the chuck claw 330, and at least one boss 332 is provided at the lower part of the clamping surface 331, and the boss 332 can also be inserted into the gap. In this setting, after the boss 332 on the chuck claw 330 is inserted into the gap between two adjacent trays 800 above and below, whether in the subsequent tray separation process or the transfer process, even if the clamping force applied by the clamping surface 331 to the clamped tray 800 is insufficient, the boss 332 can still support the tray 800, that is, the chuck claw 330 fixes the tray 800 in a way of clamping and supporting the bottom, which can ensure the fixation of the chuck mechanism to the tray 800 and the smoothness of the tray 800 and the feeding components 900 thereon during the transfer process.

[0044] It should be noted here that in other embodiments of the present application, the uppermost tray 800 can also be adsorbed and then tray separation and transfer are performed, but it is necessary to ensure that the adsorption force is sufficient and there must also be sufficient space above the tray 800.

[0045] Specifically, in this embodiment, as Figures 4 to 7 shown, two bosses 332 are provided on the clamping surface 331 of each chuck claw 330, and the end of the tray separating claw 420 corresponding to the chuck claw 330 is located between the two bosses 332. In this setting, when the tray separating claw 420 applies a downward acting force, the two chuck claws 330 on both sides can stably clamp the tray 800, so that the clamped tray 800 is not easily deflected. Of course, in other embodiments of the present application, the number of bosses 332 provided on the clamping surface 331 of each chuck claw 330 is not limited to two. For example, only one boss 332 can be provided on the clamping surface 331 of each chuck claw 330. At this time, in order to ensure the stability of the clamped tray 800 during tray separation, the two tray separating claws 420 can be arranged between the two bosses 332 provided on the two chuck claws 330 on the same side.

[0046] Specifically, in this embodiment, on one side of the two movable plates 320 facing each other, two sub-disk driving members 410 and two chuck jaws 330 are provided. The two chuck jaws 330 are arranged in one-to-one correspondence with the two sub-disk driving members 410, and at least one chuck jaw 330 and its corresponding sub-disk driving member 410 are adjustable in position along the first horizontal direction. In this setting form, by adjusting the positions of the chuck jaw 330 and its corresponding sub-disk driving member 410 along the first horizontal direction, the chuck jaw 330 and the sub-disk jaw 420 can apply a clamping or peeling force to different positions of the tray 800 along the first horizontal direction; it is also possible to make the tray transfer device provided in this embodiment clamp, separate, and transfer trays 800 with different dimensions along the first horizontal direction. Moreover, at this time, the tray transfer device provided in this embodiment can transfer rectangular trays 800 with different lengths and widths, with better compatibility and a larger applicable range.

[0047] Preferably, in this embodiment, along the first horizontal direction, the four chuck jaws 330 and the four sub-disk driving members 410 are all adjustable in position. With this setting, the flexibility of the tray transfer device provided in this embodiment is better.

[0048] Specifically, in this embodiment, as Figure 3 and Figure 4 shown, the conveying frame 200 is further provided with a positioning mechanism. The positioning mechanism includes a positioning driving member 510. The output end of the positioning driving member 510 is provided with a movable positioning member 520. The positioning driving member 510 is used to drive the movable positioning member 520 to move along the first horizontal direction. In this setting form, within its movable range, the movable positioning member 520 can position and limit trays 800 with different dimensions along the first horizontal direction, with relatively good compatibility and a relatively large applicable range.

[0049] Specifically, in this embodiment, continuing as Figure 3 and Figure 4 shown, the positioning driving member 510 is fixedly connected with a fixing plate 530. The fixing plate 530 is installed on the mounting plate 230 in a position-adjustable manner along the first horizontal direction. In this setting form, by adjusting the position of the fixing plate 530, and then adjusting the positions of the positioning driving member 510 and the movable positioning member 520, and in cooperation with the stroke range of the movable positioning member 520, the movable positioning member 520 can position and limit trays 800 within a larger dimension range along the first horizontal direction, with better compatibility and a larger applicable range. Of course, in other embodiments of the present application, the positioning driving member 510 can also be directly installed on the mounting plate 230 and be adjustable in position along the first horizontal direction.

[0050] Specifically, in this embodiment, as Figure 3As shown, the positioning mechanism further includes a fixed positioning member 540 which is fixedly arranged on the conveying rack 200. The fixed positioning member 540 and the movable positioning member 520 respectively position opposite sides of the clamped tray 800. More specifically, the fixed positioning member 540 and the movable positioning member 520 respectively position opposite sides of the clamped tray 800 along the first horizontal direction. With such an arrangement, each clamping jaw 330, the fixed positioning member 540 and the movable positioning member 520 can over-press and clamp each side of the tray 800, thereby ensuring the stability of the tray 800 during the transfer process.

[0051] Moreover, the fixed positioning member 540 and the movable positioning member 520 cooperate with each other, and the cost of the positioning mechanism is relatively low. And due to the setting of the fixed positioning member 540, the positioning error will be relatively small. Of course, in other embodiments of the present application, the fixed positioning member 540 may not be provided, but positioning driving members 510 may be provided at both ends of the tray 800 along the first horizontal direction, and the movable positioning member 520 positions and limits opposite sides of the tray 800 along the first horizontal direction.

[0052] More specifically, in this embodiment, the number of the fixed positioning members 540 is two, and the number of the positioning driving members 510 is also two. The two positioning driving members 510 are symmetrically arranged on the two mounting plates 230. In this way, there are four positioning members to position and limit opposite sides of the tray 800, and the stability of the tray 800 will be better, and the position consistency of different trays 800 will also be better.

[0053] Specifically, in this embodiment, as Figure 2 shown, the base frame 100 is provided with two guide rails 140 extending along the conveying direction; the conveying rack 200 further includes two conveying plates 210. Both of the two conveying plates 210 are provided with sliders (not shown in the figure) and are slidably arranged on the two guide rails 140 through the sliders. The guide rails 140 play a guiding role for the conveying rack 200.

[0054] Specifically, in this embodiment, both ends of the mounting plate 230 are respectively connected to the two conveying plates 210. More specifically, each end of each mounting plate 230 is fixedly connected to the corresponding conveying plate 210 through a "Z"-shaped connecting plate 220, and the mounting plate 230 is located below the conveying plate 210. In this way, it is convenient to make reasonable use of the space above and below the mounting plate 230.

[0055] In this embodiment, at least one mounting plate 230 is connected to the two conveying plates 210 in a position-adjustable manner along the conveying direction. In this setting form, the distance between the two mounting plates 230 is adjustable. Combining with the stroke range of the clamping jaws 330, the tray transfer device provided in this embodiment will be able to clamp, divide and transfer trays 800 within a larger size range along the conveying direction, with better compatibility and a larger applicable range.

[0056] Preferably, in this embodiment, along the conveying direction, the positions of the two mounting plates 230 are adjustable. With such a setting, the flexibility of the pallet transfer device provided in this embodiment is further improved.

[0057] Regarding the structure and form of adjusting the position of the components in this embodiment, as Figure 3 shown, a plurality of adjustment holes can be provided along the adjustment direction, and the component to be adjusted can be fixed to different adjustment holes through fasteners. For example, the conveying plate 210 is provided with a plurality of first adjustment holes 211 along the conveying direction, and the mounting plate 230 can be fixed to different first adjustment holes 211 along the conveying direction, and the fixing positioning member 540 can also be fixed to different first adjustment holes 211 along the conveying direction; for another example, the mounting plate 230 is provided with a plurality of second adjustment holes 232 along the first horizontal direction, and the fixing plate 530 can be fixed to different second adjustment holes 232 along the first horizontal direction, so as to be able to adjust the positions of the positioning driving member 510 and the movable positioning member 520 along the first horizontal direction; furthermore, the movable plate 320 is provided with a plurality of third adjustment holes 321 along the first horizontal direction, and the chuck jaws 330 can be fixed to different third adjustment holes 321 along the first horizontal direction.

[0058] Regarding the structure and form of adjusting the position of the components in this embodiment, one or more adjustment slots can also be provided along the adjustment direction, and the component to be adjusted can be fixed to different adjustment slots or different positions of the same adjustment slot through fixing members. For example, the movable plate 320 is provided with a plurality of adjustment slots 322, and the plurality of adjustment slots 322 are arranged at intervals along the first horizontal direction and all extend along the first horizontal direction, and the disk separating driving member 410 can be fixed to different positions of different adjustment slots 322.

[0059] In this embodiment, the mounting plate 230 is further provided with a guiding slot 231 extending along the first horizontal direction. The fixing plate 530 has a width matching that of the guiding slot 231, is arranged in the guiding slot 231, and can slide along the guiding slot 231.

[0060] Specifically, in this embodiment, as Figure 2 shown, the base frame 100 is further provided with a conveying mechanism 600. The conveying mechanism 600 includes a conveying driving member 610 and a transmission assembly. The conveying driving member 610 is in transmission connection with the conveying frame 200, and the conveying driving member 610 transfers the conveying frame 200 along the conveying direction through the transmission assembly. When the chuck mechanism and the positioning mechanism on the conveying frame 200 complete the clamping of the pallet 800 or the pallet 800 and the feeding components 900 thereon, and the disk separating mechanism has also completed the peeling of the clamped pallet 800 and the pallet below it, the conveying mechanism 600 can move the conveying frame 200 to the target position.

[0061] More specifically, the conveying driving member 610 may be a rotary driving member or a linear driving member.

[0062] When the conveying driving member 610 is a rotating driving member such as a servo motor, the transmission assembly may include a driving pulley 620, a driven pulley 640 and a conveyor belt 630, the driving pulley 620 is in transmission connection with the rotating driving member, the driven pulley 640 and the driving pulley 620 are spaced apart along the conveying direction, the conveyor belt 630 is wound around the driving pulley 620 and the driven pulley 640, and the conveyor belt 630 is fixedly connected to the conveying plate 210, for example, by a linkage member 650. Figure 2 As shown, the conveying mechanism 600 and the conveying belt 630 used in this embodiment have a wide travel range and a relatively large application range.

[0063] When the conveying drive member 610 is a rotating drive member such as a servo motor, the transmission assembly may further include a meshingly connected driving gear and a driven rack, the driving gear is transmission-connected to the rotating drive member, and the driven rack is fixedly connected to the conveying frame 200; alternatively, the transmission assembly includes a lead screw and a matching nut, the lead screw is extended along the conveying direction and is transmission-connected to the rotating drive member, the nut is sleeved outside the lead screw and is fixedly connected to the conveying frame 200; alternatively, the transmission assembly includes a driving sprocket, a driven sprocket and a conveying chain, the driving sprocket is transmission-connected to the rotating drive member, the driven sprocket is spaced apart from the driving sprocket along the conveying direction, the conveying chain is wound around the driving sprocket and the driven sprocket, and the conveying chain is fixedly connected to the conveying frame 200.

[0064] When the conveying drive member 610 is a linear drive member, it can be a cylinder or a hydraulic cylinder, etc. In this case, the conveying mechanism 600 is suitable for application scenarios with a relatively short conveying distance.

[0065] Specifically, in this embodiment, Figure 1 As shown, the base frame 100 includes a plurality of bottom plates 110 extending along a first horizontal direction and spaced apart along a conveying direction, vertical plates 120 are provided at both ends of the bottom plate 110, two support plates 130 extending along the conveying direction are respectively fixedly provided on the plurality of vertical plates 120 at the same end, and a guide rail 140 is provided on the support plate 130, and a limit member 150 is further provided on the support plate 130, and the limit member 150 is located at the end of the guide rail 140, for blocking the conveying frame 200 to prevent it from detaching from the guide rail 140.

[0066] In addition, the support plate 130 is further provided with a travel switch 160. A baffle is provided on the linkage member 650 connecting the conveyor belt 630 and the conveyor frame 200. When the baffle moves to the sensing cavity of the travel switch 160, the conveyor driving member 610 can be controlled to stop operating. The conveyor driving member 610 and the driving pulley 620 of the conveying mechanism 600 are arranged on a vertical plate 120, and the driven pulley 640 is arranged on another vertical plate. The vertical plate can also be provided with a tension adjusting member 170 to adjust the position of the driven pulley 640 relative to the driving pulley 620, thereby adjusting the tension of the conveyor belt 630.

[0067] Using the pallet transfer device provided in this embodiment, as Figure 8 shown, the feeding process is roughly as follows: S1, the pallet 800 is lifted from the bottom to the in-place position; S2, the chuck cylinder extends to clamp the uppermost pallet 800; S3, the remaining pallets 800 descend and the tray separation cylinder pushes downward; S4, after the positioning cylinder completes the positioning, the conveying mechanism 600 drives the conveyor frame 200 and the pallet 800, etc. to move along the guide rail 140.

[0068] In summary, for the pallet transfer device provided in this embodiment, since the mounting plate 230 of the conveyor frame 200, the chuck jaws 330 of the chuck mechanism, the tray separation driving member 410, the movable positioning member 520 and the fixed positioning member 540 of the positioning mechanism, etc. can all be adjusted in position, and the length of the conveyor belt 630 and the position of the travel switch 160 can also be designed or set as needed. Therefore, the pallet transfer device provided in this embodiment has good compatibility and a wide range of applications. When the size and model of the pallet 800 change, there is no need to replace the components of the conveyor frame 200, and only relevant adjustments are required. It has high efficiency, high equipment utilization rate, and can also save labor costs.
