Description

Technical Field

[0001] This utility model belongs to the field of robot equipment technology, and specifically relates to a positioning device that facilitates the grasping of a tray. Background Technology

[0002] In robotic applications, there are scenarios where robots need to grasp stacked materials, such as stacked foam pallets. When a robot grasps stacked pallets, the pallets may stick together; that is, when grasping an upper pallet, the lower pallet may be grasped along with it because it is stuck too tightly to the upper pallet.

[0003] Therefore, a positioning device is needed to facilitate pallet gripping, separate the upper and lower pallets, and prevent them from sticking together. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a positioning device that facilitates the gripping of a tray.

[0005] To solve the above-mentioned technical problems, this utility model provides a positioning device for easy pallet gripping. Its main features include a base with a receiving area for accommodating stacked pallets. At least one side of the receiving area is provided with a positioning mechanism, which includes a first limiting post and a second limiting post. The first limiting post has several spaced-apart first limiting blocks arranged from top to bottom, and the second limiting post has several spaced-apart second limiting blocks arranged from top to bottom. The first and second limiting blocks are used to alternately restrict pallets at different levels in the stacked pallets. The first and second limiting posts are movable relative to the receiving area so that when gripping a pallet, the first and second limiting posts alternately enter a restricted state and a disrestricted state.

[0006] Preferably, a first positioning mechanism and a second positioning mechanism are respectively provided on opposite sides of the accommodating area, and the first limiting post in the first positioning mechanism and the first limiting post in the second positioning mechanism are diagonally distributed, as are the second limiting post in the first positioning mechanism and the second limiting post in the second positioning mechanism.

[0007] Preferably, the positioning mechanism includes a support frame, which is mounted on the base, and the first and second limiting posts are movable relative to the support frame via a drive cylinder.

[0008] Preferably, the first limiting post and the second limiting post are arranged alternately on the support frame.

[0009] Preferably, the first limiting block corresponds to the trays of odd-numbered layers, and the second limiting block corresponds to the trays of even-numbered layers.

[0010] The positioning device of this utility model facilitates pallet gripping. It uses a first limiting post and a second limiting post to alternately limit the pallet during gripping. That is, when the robot grips the upper pallet, the corresponding limiting post is released from the restriction, thereby achieving the purpose of preventing adhesion. Attached Figure Description

[0014] To make the technical problem solved by this utility model clearer, the present utility model is further described below with reference to embodiments and accompanying drawings. The specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0015] like Figures 1 to 3 The image shows an embodiment of the positioning device for facilitating pallet gripping according to the present invention. The positioning device includes a base 1, which has a receiving area 2 for accommodating stacked pallets 8. In this embodiment, positioning mechanisms are respectively provided on opposite sides of the receiving area 2.

[0016] The positioning mechanism includes a first limiting post 3 and a second limiting post 4. The first limiting post 3 has four spaced first limiting blocks 6 arranged from top to bottom, and the second limiting post 4 has four spaced second limiting blocks 5 arranged from top to bottom. The first limiting blocks 6 and the second limiting blocks 5 are used to alternately restrict the pallets at different levels in the corresponding stacked pallets 8. The first limiting post 3 and the second limiting post 4 are movable relative to the accommodating area 2 so that when the pallet is grasped, the first limiting post 3 and the second limiting post 4 are alternately in a limiting state and an unrestricted state.

[0017] The first limiting post 3 in the left positioning mechanism and the first limiting post 3 in the right positioning mechanism, as well as the second limiting post 4 in the left first positioning mechanism and the second limiting post 4 in the right positioning mechanism, are diagonally distributed.

[0018] The positioning mechanism includes a support frame, which is mounted on the base 1. The first limiting post 3 and the second limiting post 4 are movable relative to the support frame via a drive cylinder.

[0019] The first limiting post 3 and the second limiting post 4 are arranged alternately on the support frame.

[0020] The first limiting block 6 corresponds to the trays of odd-numbered layers, and the second limiting block 5 corresponds to the trays of even-numbered layers.

[0021] Specifically, such as Figure 3 As shown, when the robot comes to grab the trays of the 1st, 3rd, 5th and 7th layers, the cylinder drives the first limit block 6 to extend. When the robot comes to grab the trays of the 2nd, 4th and 6th layers, the cylinder drives the second limit block 5 to extend, thereby achieving the purpose of preventing adhesion.

[0022] The positioning device of this utility model facilitates pallet gripping. It uses a first limiting post and a second limiting post to alternately limit the pallet during gripping. That is, when the robot grips the upper pallet, the corresponding limiting post is released from the restriction, thereby achieving the purpose of preventing adhesion.

[0023] The above descriptions are specific embodiments of this utility model and do not constitute a limitation on the scope of protection of this utility model. Any modifications and variations made to the technical concept of this utility model should be included within the scope of protection of this utility model.
