[0034] Example

[0035] The present invention provides a palletizing device, such as a robot or a gantry, comprising a main body and a palletizing fixture 10 connected to the main body. The palletizing fixture 10 can be provided in one or more configurations to facilitate palletizing loads 30 of different sizes or quantities.

[0036] Furthermore, it should be noted that the palletizing fixture 10 provided by this application, when used independently, can also adapt to different load 30 specifications or achieve simultaneous palletizing of multiple loads 30, and reduce the possibility of damage to the load 30 during the clamping process, thereby improving palletizing efficiency, increasing versatility, reducing labor costs, and meeting the market demand for palletizing diverse loads 30. The specific structures of the various components of the palletizing fixture 10 provided in this embodiment and the corresponding relationships between them will be explained in detail below.

[0037] See also Figure 1 , Figure 1 Schematic diagram of a palletizing fixture 10 provided in an embodiment of the present invention. The present invention provides a palletizing fixture 10 comprising a positioning panel 100, a pickup mechanism 300, and a clamping mechanism 500. The pickup mechanism 300 is connected to the positioning panel 100 and is configured to move in a first direction 910 to pick up a load 30. The clamping mechanism 500 is connected to the positioning panel 100 and is configured to move in a second direction 930 to clamp the load 30. The first direction 910 is perpendicular to the second direction 930.

[0038] like Figure 2 As shown, taking the first direction 910 as the horizontal direction and the second direction 930 as the vertical direction as an example, when it is necessary to pick up the load 30, the picking mechanism 300 moves along the first direction 910 to pick up and horizontally lift the load 30. At this time, to prevent the load 30 from shaking or swaying as the palletizing fixture 10 moves, the clamping mechanism 500 moves in the second direction 930 to vertically limit the load 30, thereby facilitating the transfer or transportation of the load 30 to a suitable location.

[0039] It is understood that during the process of picking up the load 30, the picking mechanism 300 and the clamping mechanism 500 work together in the vertical direction to achieve clamping or loosening. Based on this, the palletizing clamp 10 provided by the present application can more easily accommodate loads 30 of different sizes by adjusting the position of the clamping mechanism 500. Furthermore, unlike traditional clamps that use clamping arms to clamp the load 30 on both sides, the supporting arrangement of the picking mechanism 300 reduces the mutual compression between the clamping mechanism 500 and the load 30, making it easier to protect the load 30 from damage.

[0040] It should also be noted that the palletizing fixture 10 may include multiple picking mechanisms 300 or pressing mechanisms 500 to simultaneously achieve palletizing of multiple loads 30. It is understandable that, since the positioning panel 100 has good load-bearing performance and load-bearing area, in some embodiments, multiple picking mechanisms 300 or pressing mechanisms 500 can be configured to be connected to one positioning panel 100, and the specific number of the above mechanisms depends on the size of the positioning panel 100. In other embodiments, such as Figure 3 As shown, the number of the picking mechanism 300, the pressing mechanism 500, and the positioning panel 100 can correspond to each other, and integration is achieved by connecting the positioning panel 100. In addition, it should be noted that when the palletizing fixture 10 is configured in a palletizing device, and the palletizing device is a robot, the positioning panel 100 can be connected to the robot body.

[0041] Figure 4 This is a schematic diagram of a pressing mechanism 500 provided in an embodiment of the present utility model. Figure 5 This is another schematic diagram of the clamping mechanism 500 provided in the embodiment of the present utility model. Figure 1 See Figure 4 and Figure 5 Next, the clamping mechanism 500 will be described in detail. Specifically, to facilitate the clamping or releasing action, the clamping mechanism 500 includes a second drive assembly 510 connected to the positioning panel 100, and a pressure plate 530 drivingly connected to the second drive assembly 510. The second drive assembly 510 is used to drive the pressure plate 530 to move along the second direction 930 to compress the load 30.

[0042] Alternatively, the second drive assembly 510 can be configured as a cylinder equipped with a solenoid valve. By adjusting the magnetic switch element on the cylinder to control the cylinder's stroke, the operator can adjust the distance between the pressure plate 530 and the load 30 to achieve the optimal compression effect on the load 30. In other embodiments, the second drive assembly 510 can also be configured as a telescopic arm, a servo motor, or a stepper motor.

[0043] Furthermore, to facilitate ensuring that the pressure plate 530 moves along a preset direction and operates smoothly, the stacking fixture 10 also includes a bearing 550, and the positioning panel 100 is provided with a plate hole that cooperates with the bearing 550; the clamping mechanism 500 also includes a guide rod 570 extending along the second direction 930, one end of the guide rod 570 is connected to the pressure plate 530, and the other end cooperates with the bearing 550. It can be understood that the provision of the above-mentioned guide rod 570 can provide additional support and guidance, ensuring that the pressure plate 530 moves along the preset path, reducing deviation, and improving positioning accuracy. Optionally, the number of guide rods 570 and bearings 550 is four, respectively provided at the four corners of the pressure plate 530, to improve the smoothness of the movement of the pressure plate 530 and improve the stacking efficiency.

[0044] See also Figure 1 、 Figure 6 and Figure 7 Next, the picking mechanism 300 will be described in detail. In some embodiments, to facilitate the realization of both movement and support functions, the picking mechanism 300 includes a first drive assembly 310 connected to the positioning panel 100, and a bearing assembly 330 drivingly connected to the first drive assembly 310. Based on the above connection relationship, the first drive assembly 310 is used to drive the bearing assembly 330 to move along the first direction 910 to pick up the load 30. Based on the above, the bearing assembly 330 can automatically pick up the load 30 under the action of the first drive assembly 310, reducing labor costs.

[0045] See also Figure 6 and Figure 7 To further standardize the movement path, the palletizing fixture 10 also includes a guide rail 210 connected to the positioning panel 100 and extending along the first direction 910. The supporting assembly 330 includes a fixing plate 331 connected to the first driving assembly 310. The fixing plate 331 defines a retaining groove 3311 that cooperates with the guide rail 210. The cooperation between the retaining groove 3311 and the guide rail 210 effectively reduces vibration and swing of the fixing plate 331, ensuring smooth operation.

[0046] In addition, the bearing assembly 330 further includes a bearing member 333 connected to the fixing plate 331 at an angle to support the load 30. In some embodiments, the bearing member 333 can be a single plate structure; in other embodiments, such as Figure 6 As shown, the supporting member 333 may also be a plurality of bottom supporting straight rods spaced apart along the third direction 950. Optionally, the supporting member 333 is perpendicular to the fixing plate 331 along the first direction 910.

[0047] Furthermore, to prevent the guide rail 210 from being damaged by impact, the palletizing fixture 10 also includes a first cover 231 and a second cover 233, both connected to the positioning panel 100, and the first cover 231 and the second cover 233 are spaced apart at opposite ends of the guide rail 210 along the first direction 910. It is understood that the first cover 231 and the second cover 233 are respectively provided at the two ends of the guide rail 210, which can effectively prevent the bearing assembly 330 and the load 30 from causing impact or collision with the guide rail 210 when moving along the first direction 910. Optionally, the first cover 231 and the second cover 233 are both electric organ covers, rubber covers, air cushion covers, or other covers with shock absorption functions.

[0048] In addition, it should be noted that to facilitate automatic alignment or placement of the load 30, the palletizing fixture 10 further includes a baffle 250 connected to the positioning panel 100, and the baffle 250 is located between the fixed plate 331 and the clamping mechanism 500. In actual use, the first drive assembly 310 adjusts the position of the fixed plate 331, thereby adjusting the distance between the fixed plate 331 and the baffle 250, thereby supporting the load 30 for automatic alignment or pushing the load 30 off the carrier 333, thereby achieving automated placement.

[0049] See also Figure 8 In some embodiments, the first drive assembly 310 includes a drive motor 311, a screw rod 313 and a nut 315. The drive motor 311 is connected to the positioning panel 100 and is driven by the screw rod 313. The end of the screw rod 313 away from the drive motor 311 is connected to the bearing assembly 330 through the nut 315. It should be noted that the drive motor 311 can accurately control the speed and position, the screw rod 313 has high lead accuracy and repeatability, and the nut 315 can convert the rotational motion of the screw rod 313 into linear motion. The combination of the three can provide high-efficiency movement and reduce energy loss. Optionally, the drive motor 311 is a servo motor, which can realize adaptive adjustment of loads 30 of different identified specifications (such as pre-identification by scanning the code at the front end of the feed, visual or manual identification of specifications), thereby being compatible with the stacking of multiple loads 30.

[0050] Furthermore, the first drive assembly 310 also includes a coupling 317 and a push block 319. The drive motor 311 is driven and connected to the screw rod 313 via the coupling 317, and the nut 315 is connected to the bearing assembly 330 via the push block 319. It should be noted that the coupling 317 ensures precise alignment between the output shaft of the servo motor and the input shaft of the screw rod 313, avoiding additional wear caused by inaccurate alignment. The design of the push block 319 increases the connection area with the bearing assembly 330, improving operational stability.

[0051] Furthermore, to improve the operational stability of the first drive assembly 310, the pickup mechanism 300 further includes a first fixing seat 351 and a second fixing seat 353, both of which are connected to the positioning panel 100. The coupling 317 cooperates with the first fixing seat 351, and the push block 319 is slidably disposed in the second fixing seat 353. It is understood that the first fixing seat 351 and the second fixing seat 353 can provide a certain support effect for the components of the first drive assembly 310, such as the coupling 317, the push block 319, and the screw rod 313, to prevent the first drive assembly 310 from falling off due to its own weight and causing the device to fail.

[0052] Taking this embodiment as an example, the working process and working principle of the palletizing fixture 10 are as follows:

[0053] When it is necessary to pick up the load 30, the first drive assembly 310 moves along the first direction 910 so that the carrier 333 is inserted into the bottom of the load 30 and horizontally lifts the load 30 to stabilize it. At this time, if the load 30 needs to be aligned and adjusted, the first drive assembly 310 moves in the opposite direction so that the baffle 250 can resist and act on the load 30. Thereafter, in order to prevent the load 30 from shaking or swinging as the palletizing fixture 10 moves, the second drive assembly 510 moves downward along the second direction 930, and the pressure plate 530 presses the load 30, thereby achieving vertical limitation of the load 30, so as to facilitate the transfer or transportation of the load 30 to a suitable position. At this time, the clamping mechanism 500 is released, the pressure plate 530 is disengaged from the load 30, the first drive assembly 310 continues to move in the opposite direction, and the baffle 250 pushes the load 30 away from the carrier 333, thereby achieving directional placement of the load 30, thereby achieving stacking.

[0054] In summary, the present application provides a palletizing fixture 10 and a palletizing device, which include a positioning panel 100, a picking mechanism 300, and a clamping mechanism 500. The picking mechanism 300 is connected to the positioning panel 100, and the picking mechanism 300 is used to move in a first direction 910 to pick up a load 30; the clamping mechanism 500 is connected to the positioning panel 100, and the clamping mechanism 500 is used to move in a second direction 930 to clamp the load 30; and the first direction 910 is perpendicular to the second direction 930. Specifically, the picking mechanism 300 and the clamping mechanism 500 work together in the second direction 930 to achieve clamping or loosening. Based on this, the palletizing fixture 10 provided by the present application can more easily adapt to loads 30 of different sizes by adjusting the position of the clamping mechanism 500. Furthermore, unlike conventional clamps that use clamping arms to clamp the load 30 on both sides, the supporting arrangement of the pickup mechanism 300 reduces the mutual compression between the pickup mechanism 300 and the load 30 , making it easier to protect the load 30 from damage.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
