[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0032] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-4 A collision-resistant quick-change gripper for an online PCB depaneling machine includes a hollow rotating platform 1, a collision sensor 2, an electric gripper 3, and a quick-release mounting mechanism 4; the collision sensor 2 is fixedly installed on the movable end of the hollow rotating platform 1.

[0033] The collision sensor 2 adopts mature technology in the industry and is model ATI robot collision sensor.

[0034] The ATI robot collision sensor can automatically reset the connection points based on changes in angle, axis, and torsion type.

[0035] An electric gripper 3 is fixedly installed on the movable end of the collision sensor 2;

[0036] The electric gripper 3 is equipped with a quick-release mounting mechanism 4 on both movable ends;

[0037] like Figure 3 As shown, the quick-release mounting mechanism 4 includes a split-type end clamping assembly 42 for clamping and fixing the PCB board and a quick-install docking assembly for limiting and fixing the split-type end clamping assembly 42; the quick-install docking assembly is installed below the movable end of the electric gripper 3; the split-type end clamping assembly 42 is connected to the quick-install docking assembly.

[0038] In this invention, the electric gripper 3 drives the split-type end clamping assembly 42 and the quick-install docking assembly to move towards each other, thus clamping and fixing the PCB board. Subsequently, the hollow rotating platform 1 drives the electric gripper 3 to move, realizing the transfer of the PCB board. During the transfer, if the split-type end clamping assembly 42 collides, the electric gripper 3 will be displaced and deflected. After the split-type end clamping assembly 42 separates from the colliding object, the collision sensor 2 can detect the displacement of the electric gripper 3. Then, the collision sensor 2 will drive the electric gripper 3 to automatically reset, ensuring the normal progress of the PCB board transfer operation.

[0039] If it is necessary to replace the split end clamping assembly 42 with a different type, the split end clamping assembly 42 can be released by using the quick-install docking assembly, and then the new split end clamping assembly 42 can be fixed by using the quick-install docking assembly.

[0040] like Figure 3 As shown, the quick-install docking assembly includes a pneumatic locking device 41 and a positioning pin 412; the upper end of the pneumatic locking device 41 is fixedly installed below the movable end of the electric gripper 3; a locking hole 411 for connecting to the split end clamping assembly 42 is opened in the middle of the lower end of the pneumatic locking device 41; positioning pins 412 are symmetrically fixedly installed on the front and rear sides of the lower end of the pneumatic locking device 41.

[0041] The pneumatic locking device 41 is connected to an air pump via an air pipe.

[0042] like Figure 3As shown, the split-type end clamping assembly 42 includes a clamping plate mounting block 421, a locking pin 422, a clamping plate 424, a mounting hole 429, and a self-locking assembly; a locking pin 422 that mates with the locking hole 411 is fixedly installed in the middle of the upper end of the clamping plate mounting block 421; positioning holes 423 that mate with the positioning pin 412 are symmetrically opened on the front and rear sides of the upper end of the clamping plate mounting block 421; mounting holes 429 are symmetrically opened on the front and rear sides of the lower end of the clamping plate mounting block 421; the clamping plate 424 is inserted into the mounting hole 429;

[0043] The lower end of the clip mounting block 421 and the clip 424 are equipped with a self-locking component for fixing the clip 424;

[0044] like Figure 4 As shown, the self-locking assembly includes a pin 426 and a return spring 428; the outer ends of the clip mounting block 421 and the outer ends of the clip 424 are provided with insertion holes 425;

[0045] The pin 426 is slidably connected to the insertion hole 425 on the clamp mounting block 421; one end of the return spring 428 is fixedly connected to the outer end of the clamp mounting block 421; the other end of the return spring 428 is fixedly connected to the pin 426.

[0046] The inner end of the pin 426 is provided with a sliding inclined surface 427; and the sliding inclined surface 427 faces downward.

[0047] The inner end of the clip 424 is provided with a rubber anti-slip pad;

[0048] In this utility model, the electric gripper 3 drives the left and right pneumatic locking devices 41, clamping plate mounting blocks 421 and clamping plates 424 to move towards each other until the clamping plates 424 abut against the side end of the PCB board, thus achieving the clamping and fixing of the PCB board.

[0049] Subsequently, the hollow rotating platform 1 operates, driving the electric gripper 3 to move and transfer the PCB board. During the transfer, if the clamping plate mounting block 421 or the clamping plate 424 collides, the electric gripper 3 will be displaced and deflected. At this time, the collision sensor 2 can detect the displacement of the electric gripper 3. When the clamping plate mounting block 421 or the clamping plate 424 separates from the colliding object, the collision sensor 2 will automatically reset the electric gripper 3, ensuring the normal operation of the PCB board transfer.

[0050] If it is necessary to replace the clamping plate mounting block 421 with a different type, the pneumatic locking device 41 will work to release the suction and fixation of the clamping plate mounting block 421, and then pull the clamping plate mounting block 421 down; so that the locking pin 422 installed at the upper end of the clamping plate mounting block 421 is separated from the locking hole 411 opened at the lower end of the pneumatic locking device 41; and the positioning pin 412 installed at the lower end of the pneumatic locking device 41 is separated from the positioning hole 423 opened at the upper end of the clamping plate mounting block 421. Then, the new clamping plate mounting block 421 is inserted into the pneumatic locking device 41, and then the air pump works and the pneumatic locking device 41 suctions and fixes the clamping plate mounting block 421, thus completing the quick replacement of the clamping plate mounting block 421.

[0051] If the clip 424 installed below the clip mounting block 421 is worn or malfunctions, pull the pin 426 outward; at this time, the pin 426 will move outward along the insertion hole 425 provided at the outer end of the clip mounting block 421. During the movement, the return spring 428 will be continuously compressed until the pin 426 separates from the insertion hole 425 on the clip 424. Then, the clip 424 that needs to be replaced is pulled out downward along the mounting hole 429.

[0052] Next, insert the new clip 424 upward along the mounting hole 429. When the upper end of the clip 424 touches the sliding inclined surface 427 opened at the inner end of the pin 426, it will drive the pin 426 to move outward along the insertion hole 425. During the movement, the return spring 428 will be continuously compressed until the pin 426 is aligned with the insertion hole 425 opened on the clip 424. The return spring 428 will reset and drive the pin 426 to move inward. At this time, the pin 426 will be inserted into the insertion hole 425 of the clip 424, thus fixing the clip 424.

[0053] The collision sensor 2 enables the device to automatically reset after a collision, providing reliable collision protection for PCB board clamping and transfer, and ensuring efficient operation of the transfer operation. Through the cooperation of the pneumatic locking device 41, the clamp mounting block 421 and the pin 426, the device can not only quickly replace different types of clamp mounting blocks 421, but also replace the clamps 424 that have worn out, reducing the standby time of the equipment and lowering maintenance costs.

[0054] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
