[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1 to 3 As shown, this utility model provides a mechanical gripper for a palletizing robot, including: a base 1, a support plate 2, a first driving component, and an adapter plate 3.

[0023] In this embodiment, the base 1 is detachably mounted on the palletizing robot. The base is mounted on the robotic arm of the palletizing robot.

[0024] There are two support plates 2. The two support plates are arranged opposite each other. The two support plates 2 are respectively vertically arranged at opposite ends of the base 1. A connecting arm 21 is formed on the upper side of the support plate 2. The support plates are arranged along the width direction of the base. Each support plate has two connecting arms. The two connecting arms are respectively arranged at opposite ends of the support plate. The connecting arm 21 is hinged to the base 1. One end of the connecting arm is connected to the upper side of the support plate. The other end of the connecting arm is hinged to the base. A row of gripping teeth 22 extends oppositely from the lower side of the two support plates 2. The row of gripping teeth includes multiple gripping teeth, which are spaced apart along the length direction of the support plate.

[0025] The first driving component is mounted on the base 1. The first driving component is used to drive the support plate 2.

[0026] In a preferred embodiment, the first driving component is an electro-hydraulic actuator. The electro-hydraulic actuator has a fixed end and a telescopic end. The fixed end is hinged to one end of the base 1. The telescopic end is hinged to the support plate 2.

[0027] In this embodiment, vertically arranged first sliding grooves are formed on opposite sides of the two support plates 2. A second sliding groove is formed on the inner side of the gripping teeth 22. The second sliding groove is arranged along the length direction of the gripping teeth 22. Slider blocks 31 are respectively hinged to opposite sides of the adapter plate 3. The slider 31 on one side of the adapter plate 3 slides in the first sliding groove. The slider 31 on the other side of the adapter plate 3 slides in the second sliding groove. A second driving member 32 for driving the slider 31 on one side of the adapter plate 3 is installed in the first sliding groove.

[0028] In a preferred embodiment, the second driving component 32 is a lead screw. The lead screw is rotatably mounted in the first slide groove. The lead screw is arranged along the length direction of the first slide groove. A motor is mounted on the support plate 2. The motor is driven by the lead screw.

[0029] In this embodiment, a pressure plate 5 is mounted on the bottom of the base 1 in a height-adjustable manner via a cylinder 51. The pressure plate 5 is positioned between two support plates 2. In this embodiment, the cylinder is vertically oriented.

[0030] In a preferred embodiment, there are two pressure plates 5. The two pressure plates 5 are spaced apart along the length of the base 1.

[0031] See Figure 3 As shown, when the mechanical gripper of this invention for a palletizing robot grasps a wider item 4, the two support plates open to a large angle under the drive of the first drive member. Simultaneously, the second drive member drives the slider in the first groove to move towards the lower side of the support plates, causing the adapter plate to flip and fit against the opposite sides of the wider item. After the adapter plate fits against the opposite sides of the item, the first drive member drives the two support plates to close, clamping the item between the adapter plate and a row of gripping teeth.

[0032] In addition, when the width of the goods (such as sheet metal parts) is narrow, the pressure plate descends under the drive of the cylinder and presses against the top of the goods, so that the goods are clamped between the gripper teeth and the pressure plate.

[0033] The mechanical gripper of this invention for palletizing robots uses an adapter plate installed between the support plate and the gripper teeth to rotate and adapt to the side angle of wider goods. This allows the adapter plate on the two support plates to clamp wider goods, thereby enabling the mechanical gripper of this invention for palletizing robots to be suitable for gripping wider goods, improving the gripping stability of wider goods, and also expanding the applicability of the equipment.
