[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] like Figure 1-Figure 6 As shown, the intelligent clamp of the embodiment of the present invention, which is suitable for grasping round bars of various specifications and can identify material information, is composed of a code reading sensor, a V-shaped roller, a lever, a roller motor, a lever cylinder or oil cylinder, a driving sprocket, a clamp frame, and two pairs of opposing switches. Specifically, a roller conveyor is formed by a plurality of V-shaped rollers 6 spaced apart and horizontally arranged on the same horizontal plane at the bottom of a frame 1, and the roller conveyor is transmission-connected to a reduction motor 5. A lever driven to move linearly is horizontally arranged above the roller conveyor, and a bar plate 2 is arranged at one end of the lever, and the bar plate is connected to the lever in an L shape. The free end of the bar plate is vertically downward and located on the feed side of the clamp, and a code reader 8 is arranged on the feed side of the clamp for identifying the identification code of the end face of the bar 100; a bar entry and exit channel space is formed between the lever and the roller conveyor.

[0025] The code reading sensor implemented in the present invention can recognize identification codes such as two-dimensional codes, bar codes, or other types of identification codes, such as code readers or code reading modules or devices.

[0026] The V-shaped roller implemented in the present invention should be compatible with round bars within a certain diameter range and can ensure that the bars are reliably positioned during the conveying process.

[0027] In an embodiment of the present invention, a pair of front facing switches 7 may be provided on the feeding side of the clamp, which is used to start the roller conveyor device to convey the bar material after detecting the front end of the bar material during the clamp picking process, and stop the roller conveyor device after detecting the rear end of the bar material leaving.

[0028] In an embodiment of the present invention, a pair of rear-facing switches 9 may also be provided on the discharge side of the clamp, which are used to start the roller conveyor device to convey the bar material after detecting the front end of the bar material during the feeding process of the clamp, and stop the roller conveyor device after detecting the rear end of the bar material leaving.

[0029] The upper surface of the top support plate of the frame in the embodiment of the present invention is provided with a linear reciprocating drive mechanism for driving the lever to move, and the lower surface of the top support plate of the frame is provided with two parallel and spaced linear guide rails 3 for the linear movement of the lever.

[0030] The linear reciprocating drive mechanism of the embodiment of the present invention is a cylinder 4 or an oil cylinder, the front end of the driving rod of which is connected to a connecting plate vertically fixed to the upper end of the lever, and the connecting plate and the bar material lever plate are respectively located at the upper end and the lower end of the lever, and are connected in a T shape. The stroke of the lever driven by the lever cylinder or oil cylinder implemented in the present invention should be compatible with round bars within a certain length range.

[0031] The load capacity of the roller reduction motor, V-shaped roller, lever cylinder or oil cylinder and frame implemented in the present invention should be designed to be compatible with round bar materials within a certain weight.

[0032] The roller conveying device of the embodiment of the present invention is connected to the reduction motor through a sprocket chain transmission mechanism. A driving sprocket 51 is provided on the driving shaft of the reduction motor. A matching double-layer sprocket 61 is installed on one axial end of the V-shaped roller. The V-shaped roller is connected by a chain (not shown) through one layer of the double-layer sprocket, and is connected to the driving sprocket through another chain (not shown) through the sprocket of the other layer of the V-shaped roller, thereby realizing transmission.

[0033] In the embodiment of the present invention, preferably, the free end of the bar stock shifting plate is higher than the V-shaped roller by a predetermined distance, and preferably, the free end thereof should be lower than the center of the cylindrical bar stock, such as Figure 6 As shown, and extends downwardly toward the surface where the bar contacts the V-shaped roller.

[0034] The V-shaped roller of the embodiment of the present invention includes a V-shaped positioning part in the middle and cylindrical parts located at both ends of the V-shaped positioning part. The V-shaped positioning part in the middle is used to position the bar material to prevent it from shifting to both ends, thereby ensuring the positioning and linear transportation of the bar material.

[0035] In an embodiment of the present invention, the arrangement of the bar stock shifting plate can preferably be arranged so that when the cylindrical bar stock is supported by the V-shaped positioning portion in the middle of the V-shaped roller, the central axis of the bar stock shifting plate can coincide with a diameter line of the cylindrical bar stock, so as to ensure that the bar stock shifting plate shifts the stock in the middle and applies a uniform shifting force to the bar stock.

[0036] In an embodiment of the present invention, lifting rings are installed near the four corners of the top surface of the frame for lifting and transporting the clamp. The clamp is lifted and transported horizontally by a lifting device or an overhead crane, and is transported horizontally or by lifting from one place to another, so that the bar material can be taken and then transported horizontally or by lifting to the destination to realize material delivery.

[0037] The intelligent fixture material taking process implemented by the present invention is as follows:

[0038] The code reading sensor recognizes the QR code, barcode and other identification codes on the end face of the bar to obtain material information. After the material is verified to be correct, the lever cylinder drives the lever to extend, and the roller motor drives the V-shaped roller to rotate by driving the sprocket. The clamp moves as a whole to the position where the bar is centered for material collection. The lever cylinder drives the lever to retract and push the bar onto the V-shaped roller. The front end of the bar is detected by the shooting switch. At this time, the rotation direction of the V-shaped roller is required to be consistent with the direction of retraction of the lever. As the lever is retracted and the V-shaped roller rotates, until the shooting switch on the bar entry side detects that the rear end of the bar has left, it means that the entire bar has been transferred to the V-shaped roller, and the roller motor stops to stop the V-shaped roller from rotating. At this point, the intelligent clamp completes the material collection process.

[0039] The feeding process of the intelligent clamp implemented by the present invention is as follows:

[0040] The rear end of the clamp is aligned with the material receiving device, and the roller motor drives the V-shaped roller to rotate by driving the sprocket. The bar moves forward with the V-shaped roller, and the front end of the bar is first detected by the shooting switch until the shooting switch on the bar output side detects that the rear end of the bar has left, indicating that the entire bar has been transferred to the material receiving device. The roller motor stops and the V-shaped roller stops rotating; at this point, the intelligent clamp completes the feeding process.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
