[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0023] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0026] Combined with Figure 1-3 A heavy-duty clamp for a pallet in this embodiment is applied to a robotic arm, and includes a connecting seat 1, an upper clamping jaw 2, a lower clamping jaw 3 and a rubber pad disk 4. The connecting seat 1 is connected to the robotic arm and moves in space under the control of the robotic arm. The upper clamping jaw 2, the lower clamping jaw 3 and the rubber pad disk 4 are all connected to the connecting seat 1. The upper clamping jaw 2 and the lower clamping jaw 3 are arranged at the same side of the connecting seat 1 with an interval between the upper and lower jaws. The connecting seat 1 is provided with a first control mechanism 13 for controlling the relative movement of the upper clamping jaw 2 and the lower clamping jaw 3. The upper clamping jaw 2 and the lower clamping jaw 3 are close to each other to achieve the clamping and fixing of the pallet. The rubber pad disk 4 is arranged at the bottom of the connecting seat 1, and the center of the rubber pad disk 4 is rotatably connected to the connecting seat 1. The rubber pad disk 4 is evenly distributed along its circumference. A second control mechanism 14 for controlling the rotation of the rubber pad disk 4 and a third control mechanism 15 for installing the rubber pad on the rubber pad disk 4 to the pallet are provided on the connecting seat 1.

[0027] The heavy-duty fixture for the pallet can realize both the automated transportation of the pallet and the automated installation of the rubber pad, which saves time and effort and is highly efficient. Moreover, the two steps are completed by the same mechanism, which has a simple structure, low cost and is easy to control.

[0028] As a preferred solution of the utility model, the lower jaw 3 is fixedly connected to the connecting base 1, and the upper jaw 2 is slidably connected to the connecting base 1 up and down. The first control mechanism 13 is a cylinder or an oil cylinder for controlling the up and down movement of the upper jaw 2. Since the lower jaw 3 is fixed, the load-bearing capacity of the lower jaw 3 can be increased to ensure the stability of the pallet during transportation.

[0029] As a preferred solution of the present utility model, the second control mechanism 14 is a motor installed on the connecting seat 1 and the output shaft is fixedly connected to the center of the rubber pad 4.

[0030] As a preferred solution of the utility model, a slide rail 5 is provided on the connecting seat 1 along the sliding direction of the upper clamping jaw 2. Multiple slide rails 5 can be provided on the connecting seat 1 at the same time. The upper clamping jaw 2 is slidably connected to the slide rail 5 through a slider 12. The cooperation between the slide rail 5 and the slider 12 is used to improve the stability of the upper clamping jaw 2 fixing the pallet.

[0031] As a preferred embodiment of the utility model, a guide tube 7 is provided on the connecting seat 1 below the rubber pad disc 4, and the third control mechanism 15 is located above the connecting seat 1 and is used to push the rubber pad in the rubber pad fixing hole 6 downward. The inner diameter of the guide tube 7 is consistent with the aperture of the rubber pad fixing hole 6. When the rubber pad disc 4 rotates, several rubber pad fixing holes 6 pass directly above the guide tube 7 one by one. The third control mechanism 15 is an air cylinder or an oil cylinder, and the output shaft of the third control mechanism 15 is arranged directly opposite to the guide tube 7, so that when the rubber pad fixing hole 6 is aligned with the guide tube 7, the rubber pad in the rubber pad fixing hole 6 is pushed downward, and pushed to the corresponding hole on the tray through the guide tube 7 for fixation.

[0032] As a preferred solution of the utility model, a positioning block 11 is provided in the rubber pad fixing hole 6. The positioning block 11 is arranged at one end of the rubber pad fixing hole 6 away from the guide tube 7. A positioning protrusion 8 is provided on the side of the positioning block 11 close to the guide tube 7. The positioning protrusion 8 cooperates with the hole in the center of the rubber pad to realize the positioning of the rubber pad. A push rod hole 9 is opened through the positioning block 11. The third control mechanism 15 includes a push rod 10 that cooperates with the push rod hole 9. The third control mechanism 15 pushes the rubber pad in the rubber pad fixing hole 6 out through the push rod 10.

[0033] As a preferred solution of the utility model, multiple push rod holes 9 are arranged around the center of the positioning block 11, and multiple push rods 10 are also arranged. Multiple push rods 10 push the rubber pad at the same time to avoid one side of the rubber pad being pushed out tilted due to force, thereby ensuring the installation effect of the rubber pad.

[0034] As a preferred solution of the utility model, in order to prevent the push rod 10 from crushing the rubber pad and affecting its aesthetics and anti-slip effect when installed on the pallet, a flexible head is provided on the end of the push rod 10 that contacts the rubber pad. The flexible head can be a rubber head or other flexible material.

[0035] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
