DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1-3 As shown, a pneumatic grab-type clamp includes a mounting frame, a connecting seat, a mounting seat, a clamping mechanism, an air circuit system, a pressure plate mechanism, a sensor assembly, and a controller; the connecting seat is mounted on the top of the mounting frame, and the mounting seat is mounted on the bottom of the connecting seat; the clamping mechanism includes a mounting plate, a grab assembly, and a telescopic cylinder, the mounting plate is fixed to the bottom of the mounting seat, the grab assembly is hinged on both sides of the mounting plate, the telescopic cylinder is mounted on both sides of the top of the mounting plate, and the piston rod of the telescopic cylinder is connected to the grab assembly; the air circuit system is connected to the telescopic cylinder; the pressure plate mechanism includes a pressure plate and a spring assembly, and the pressure plate is mounted below the mounting plate through the spring assembly; the sensor assembly includes a posture sensor, a pressure sensor and an air pressure sensor, the posture sensor is mounted on the grab assembly, the pressure sensor is mounted on the bottom of the pressure plate, and the air pressure sensor is mounted on the air circuit system; the controller is mounted on the mounting frame, the controller is electrically connected to the air circuit system, a detection module is provided in the controller, and the detection module is electrically connected to the posture sensor, the pressure sensor and the air pressure sensor.

[0022] like Figure 2As shown, the clamping mechanism also includes a cylinder support seat, which is installed on the front and rear sides of the top of the mounting plate, and the left and right ends of the cylinder support seat are respectively connected to the telescopic cylinder. That is, the telescopic cylinder is fixed to the left and right sides of the top of the mounting plate through the cylinder support seat, and two telescopic cylinders are respectively fixed on the left and right sides of the top of the mounting plate. Through this arrangement, the grab assembly can be better pushed to open and close for grabbing and clamping.

[0023] like Figure 2 As shown, the grab assembly includes a connecting plate, a support rod, a connecting block, a supporting claw, and a connecting shaft. The lower end of the support rod is connected to the connecting plate by bolts, the top of the support rod is hinged on the connecting block, the connecting block is fixedly connected to the piston rod of the telescopic cylinder, the supporting claw is fixedly connected to the bottom of the connecting plate, two supports are respectively arranged on the left and right sides of the mounting plate, and the top of the connecting plate is hinged to the two supports on one side of the mounting plate through the connecting shaft. When working, the piston rod of the telescopic cylinder moves outward, driving the connecting block to move outward, thereby driving the support rod to rotate inward, and pushing the connecting plate to rotate inward, so that the two supporting claws are close to each other, that is, the two grab assemblies form a clamping state to grab and clamp the material.

[0024] like Figure 2 As shown, the air circuit system includes an external air pump, a first pneumatic connection port, a second pneumatic connection port, a first air pipe, and a second air pipe. The first pneumatic connection port and the second pneumatic connection port are respectively arranged on a mounting seat. The first pneumatic connection port and the second pneumatic connection port are both connected to the external air pump. The first air pipe is connected to the first pneumatic connection port, and the second air pipe is connected to the second pneumatic connection port. The first air pipe and the second air pipe are also connected to a branch air pipe, which is arranged in a mounting plate and is respectively connected to a corresponding interface of the telescopic cylinder. The controller is electrically connected to the external air pump. The controller controls the air circuit system by controlling the external air pump, and then controls the operation of the telescopic cylinder.

[0025] like Figure 3 As shown, the spring assembly includes a fixed cylinder, a slide bar, and a spring. The fixed cylinder passes through the mounting plate and is fixedly connected to the four corners of the mounting plate by bolts. One end of the slide bar is fixedly connected to the pressure plate, and the other end of the slide bar is slidably connected in the fixed cylinder. The spring is sleeved on the outside of the slide bar, and the spring is located below the fixed cylinder. When the grab assembly grabs and clamps the material, the material will press upward against the pressure plate, causing the pressure plate to move upward. The upward movement of the pressure plate will compress the spring, and the spring will squeeze the pressure plate downward under the action of the rebound force, thereby causing the pressure plate to press the material on the grab assembly to prevent the material from falling, thereby improving the stability of the grab assembly clamping.

[0026] In this embodiment, the air pressure sensor is arranged at the first pneumatic connection port, the second pneumatic connection port and the interface of the telescopic cylinder; the posture sensor is installed on the connecting plate; and the pressure sensor is installed at the bottom of the pressure plate.

[0027] Specifically, the air pressure sensor is arranged at the interface of the first pneumatic connection port, the second pneumatic connection port and the telescopic cylinder, with the purpose of detecting the air pressure values ​​and air pressure changes at different positions of the air circuit system. After the air pressure sensor feeds back the data to the detection module, the detection module determines whether the telescopic cylinder is working normally and whether there is a fault in the air circuit system through the air pressure value; the posture sensor is installed on the connecting plate, and can feed back the data of the movement state of the connecting plate to the detection module, and judge whether the grab assembly is working normally through the detection module; the pressure sensor is arranged at the bottom of the pressure plate, and can feed back the pressure data between the material and the pressure plate to the detection module, and judge through the detection module whether the pressure plate effectively presses and fixes the material grabbed and clamped by the grab assembly.

[0028] The above-mentioned sensors can effectively detect and monitor the air system, grab assembly and pressure plate mechanism, and feed back the data to the detection module in a timely manner. The detection module can judge the working status of the clamp through the data fed back by the sensor. When encountering abnormal conditions, the detection module can feed back the abnormal situation to the controller in a timely manner and promptly remind and respond through the controller, thereby improving the safety of the operation, avoiding material loss and improving work efficiency.

[0029] The working principle of the utility model is as follows:

[0030] The operation of the air circuit system is controlled by the controller, and then the operation of the telescopic cylinder is controlled. The piston rod of the telescopic cylinder moves outward, driving the two grab assemblies to move closer to each other to form a clamping state to grab and clamp the material. At the same time, the pressure plate presses the material downward under the action of the spring assembly, thereby improving the stability of the clamping. In this process, through the cooperation of the air pressure sensor, posture sensor and pressure sensor with the detection module, it can detect and determine whether the telescopic cylinder is working normally, whether the clamp is opened and closed normally for effective grabbing, and whether the pressure plate has pressed and fixed the material. The working state of the clamp can be effectively detected and monitored to improve work efficiency.

[0031] In general, the utility model can effectively grasp and clamp materials by setting up a clamping mechanism, an air circuit system and a pressure plate mechanism. The pressure plate mechanism can press and fix the materials, improve the stability of the clamping, and prevent the materials from falling during the handling process, which not only improves the work efficiency but also reduces the safety hazards. By setting up a sensor component and a detection module, it can detect and judge whether the telescopic cylinder is working normally, whether the clamp is opened and closed normally for effective grasping, whether the pressure plate has pressed and fixed the materials, and effectively detect and monitor the working status of the clamp, and provide timely feedback and reminders to improve work efficiency.

[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
