Background Art

[0002] In the photovoltaic industry, when the workshop is producing, it is necessary to position the crystal tray and then process the workpiece. However, the existing methods are generally to grab by a manipulator, move the truss into position, or grab by a robot. However, these operations are all rough positioning and cannot accurately position the crystal tray. The crystal tray and the workpiece are relatively large. When the whole is driven to move, because there is no clamping positioning, sometimes the displacement found cannot be detected, which affects the subsequent processing. If the robot gripper is used to release the crystal tray before the next step after it is in place, it is easy to bring out the crystal tray and the workpiece. As a result, the subsequent work cannot be carried out. The overall production efficiency is greatly affected. Utility Model Content

[0023] Example 1

[0024] A positioning clamping anti-separation mechanism, such as Figure 1-Figure 4 As shown, it includes a mechanism fixing plate 2; a dead stop 9 is arranged on the mechanism fixing plate 2, and a proximity switch 12 is arranged on the dead stop 9; a positioning clamp 3 for clamping and positioning the crystal holder 13 is arranged adjacent to the proximity switch 12; a joint is arranged in the middle of the positioning clamp 3, and the end of the joint is connected to the cylinder rod of the cylinder 10; the positioning clamp 3 includes two clamps, and the joint is arranged between the two clamps, each clamp and the joint are connected by a connecting rod 5, and the two connecting rods 5 are connected to the joint by a hinge pin 4.

[0025] The connecting rod 5 is connected to the clamping jaw via a hinge pin 4 .

[0026] Two proximity switches 12 are provided, and the proximity switches 12 are provided on the dead stop 9 via a switch bracket.

[0027] The end of the joint is connected to the front end of the cylinder rod of the cylinder 10 through the optical axis 6, and a supporting guide 8 is arranged on the outer periphery of the optical axis 6.

[0028] The supporting guide member 8 is arranged on the bearing seat 7 , and the bearing seat 7 is arranged on the mechanism fixing plate 2 .

[0029] The cylinder 10 is arranged on the positioning main board 1 , and the cylinder 10 is closed on the positioning main board 1 .

[0030] The supporting guide member 8 is a linear bearing or a copper sleeve.

[0031] A link seat 11 is provided at one end of the mechanism fixing plate 2 ; the link seat 11 is used to connect and fix the positioning clamping anti-separation mechanism with other equipment, including but not limited to transplanters, trusses, and robots. The link seat 11 is preferably provided at the end opposite to the positioning clamp 3 .

[0032] The mechanism is also equipped with a PLC control system, and the cylinder 10 and the proximity switch 12 are respectively connected to the PLC control system. And a certain fixed model is locally limited to achieve its specific working function.

[0033] During specific operation, take the installation of the utility model mechanism in the gripper of the existing truss as an example, connect it to the corresponding ball screw nut on the truss gripper through the link seat 11, and drive the mechanism to take and discharge materials into the slicer through the screw of the truss gripper. The above is only to illustrate a specific working method of the present application, and the present application is not limited to this method. When the positioning, clamping and anti-separation mechanism of the utility model is in place, the cylinder 10 drives the cylinder rod to contract forward and backward, and then drives the joint to clamp the crystal support 13 with two claws driven by the hinge pin 4 and the connecting rod 5. The positioning is accurate by clamping and positioning with the positioning jaws 3 and the positioning groove on the crystal support 13. A linear bearing or a copper sleeve is set on the optical axis 6 for guiding and bearing radial force, and the joint is connected to the connecting rod 5 to drive the hand gripper to clamp and position. The hand grips on both sides are symmetrical. When clamping, the clamping surface is the V-shaped surface of the positioning groove of the crystal support 13. The head end of the crystal support 13 is against the dead stop 9 to achieve clamping. At this time, the three points of the rotating parts of the two connecting rods 5 and the hinge pin parts of the joint are in the same straight line, and the dead point of the stroke. This dead point can ensure that the clamp will not open when it is not subjected to external forces other than the axial force, thereby making the clamp safer and more reliable. After processing, the crystal support 13 and the workpiece are moved to the position to be released through the truss and the gripper, and the positioning clamp 3 begins to release. The release process is the opposite of the clamping process. The connecting rod 5 dead point is destroyed by extending the cylinder 10, thereby releasing the crystal support 13 and achieving the separation of the crystal support 13. Two left and right proximity switches 12 are set at the front end of the mechanism to detect the state of the crystal support 13. When the crystal support 13 is in the clamping state, any one of the proximity switches 12 has a signal interruption, which can determine that the crystal support 13 has displacement, and feedback to the PLC control system, interrupting the processing, and resuming the processing after the fault is eliminated. When the crystal support 13 is in the released state, the two proximity switches 12 should be in the non-triggered state. If any one of the two proximity switches 12 has a trigger signal, it can be determined that the crystal support 13 is not safely released, and the processing is immediately interrupted and resumed after the fault is eliminated.

[0034] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
