[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Example 1

[0026] An integrated suction clamping mechanism for ZR components in a clamping device, such as Figures 1-5 As shown, it includes ZR shaft 1, which is the core support component of the entire mechanism. A vent 4 is provided at the center of its interior. The vent 4 is used to transmit gas and realize the negative pressure adsorption function of the suction nozzle 606.

[0027] The top of the ZR shaft 1 has an internal ventilation connection thread 3, which is threaded to the external ventilation component. Through this connection method, the external air source can be connected to the ventilation hole 4 to provide a stable negative pressure air source for the suction nozzle 606.

[0028] ZR shaft 1 outer side is provided with two groups of ball spline 12 connected, ZR shaft 1 outer side both ends are provided with reciprocating ball way 2, and two groups of ball spline 12 inside are movably connected with multiple groups and reciprocating ball way 2 matched ball, reciprocating ball way 2 section is arc-shaped, and the radian of arc-shaped is consistent with the roundness of ball of ball spline 12, the cooperation of ball spline 12 and reciprocating ball way 2 makes that ZR shaft 1 moves in axial direction, ball can roll in reciprocating ball way 2, so as to ensure the smoothness of ZR shaft 1 movement, can also bear certain radial force, improve the stability of mechanism;

[0029] ZR shaft 1 outer side is fixed with bearing 11 located at the top and bottom of ball spline 12, and bearing 11 is movably connected with external support frame, and bearing 11 can rotate radially and move axially relative to ZR shaft 1, the function of bearing 11 is to support ZR shaft 1, so that it can stably rotate and move on the external support frame, during the working process of the mechanism, ZR shaft 1 needs to reciprocate axially and possibly rotate, bearing 11 can effectively reduce friction resistance, improve the motion efficiency of the mechanism, and prolong the service life of the mechanism;

[0030] ZR shaft 1 outer side is provided with a belt pulley 10 fixed on the top of a group of bearings 11, and the outer thread 9 matched with the belt pulley 10 is arranged on the outer side of the ZR shaft 1, the belt pulley 10 is connected with the power source through the belt, when the power source drives the belt pulley 10 to rotate, the radial rotation of ZR shaft 1 can be driven, so as to realize the rotation of the jaw suction nozzle mechanism 6, meet the position requirement of clamping and inserting operation;

[0031] The jaw suction nozzle mechanism 6 includes a connecting cylinder 601, a jaw 602, a suction nozzle 606, a rotating hole 603, a driving groove 604 and a driving piston rod 605. The connecting cylinder 601 is located at the bottom of the quick connecting assembly 5 and serves to connect the jaw 602 and the suction nozzle 606. An internal cavity is provided in the connecting cylinder 601 to connect the air vent hole 4 and the suction nozzle 606, so that the negative pressure can be smoothly transmitted from the air vent hole 4 to the suction nozzle 606, realizing the adsorption of electronic components.

[0032] The suction nozzle 606 is located at the bottom center of the connecting cylinder 601, and its shape and size are designed according to the electronic components to be clamped, which can be well fitted with the surface of the electronic components and stably adsorb the electronic components under the action of negative pressure.

[0033] Two groups of clamping jaws 602 are located at the bottom of the connecting cylinder 601 and are rotationally connected thereto. The clamping jaws 602 and the connecting cylinder 601 are rotationally connected through the rotating shaft in the rotating hole 603. The driving grooves 604 opened at the ends of the two groups of clamping jaws 602 are located inside the connecting cylinder 601. The driving piston rod 605 is slidingly connected inside the connecting cylinder 601. The driving head provided at the bottom of the driving piston rod 605 is located inside the two groups of driving grooves 604. The piston provided at the top of the driving piston rod 605 is sealingly and slidingly connected to the connecting cylinder 601.

[0034] When the driving piston rod 605 moves upward, the driving head at the bottom thereof drives the clamping jaws 602 to rotate around the rotating hole 603 through the driving grooves 604, so as to open the clamping jaws 602. When the driving piston rod 605 moves downward, the clamping jaws 602 are closed.

[0035] This design enables the clamping jaws 602 and the suction nozzle 606 to work cooperatively. For electronic components of different shapes and sizes, the suction nozzle 606 can be used to adsorb and position the electronic components, and then the clamping jaws 602 can be used to firmly clamp the electronic components, so as to effectively solve the problems existing in pure mechanical clamping or single negative pressure adsorption.

[0036] The connecting cylinder 601 is provided with a buffer spring 7. The two ends of the buffer spring 7 are fixedly connected to the connecting cylinder 601 and the top of the driving piston rod 605, respectively. The buffer spring 7 provides buffering during the movement of the driving piston rod 605, so as to prevent the driving piston rod 605 from moving too fast and causing impact on the clamping jaws 602 and the electronic components. For example, when the clamping jaws 602 contact the surface of the electronic components during clamping, the buffer spring 7 can absorb part of the impact force, so that the clamping jaws 602 can clamp the electronic components more gently, thereby avoiding damage to the electronic components.

[0037] The quick connection assembly 5 is connected between the bottom of the ZR shaft 1 and the clamping jaw suction nozzle mechanism 6. The main function of the quick connection assembly 5 is to quickly and conveniently connect and disassemble the ZR shaft 1 and the clamping jaw suction nozzle mechanism 6. In actual production, different specifications of the clamping jaw suction nozzle mechanism 6 may need to be replaced according to different clamping requirements of the electronic components. The quick connection assembly 5 can be conveniently replaced, thereby improving the production efficiency and reducing the equipment maintenance cost.

[0038] The overall working process is as follows:

[0039] The clamping jaws 602 are in an open state, the driving piston rod 605 is in a higher position, and the buffer spring 7 is in a stretched state.

[0040] The external air passage is in communication with the air hole 4 of the ZR shaft 1 through the air passage connecting thread 3, so as to generate negative pressure. The negative pressure is transmitted to the suction nozzle 606 through the internal cavity of the connecting cylinder 601, and the suction nozzle 606 adsorbs the electronic components.

[0041] When the suction nozzle 606 adsorbs the electronic component, the driving piston rod 605 moves downward, the bottom driving head drives the clamping jaw 602 to rotate around the rotating hole 603 through the driving groove 604, the clamping jaw 602 is closed, and the electronic component is firmly clamped.

[0042] After the clamping jaw 602 and the suction nozzle 606 firmly clamp the electronic component, the ZR shaft 1 accurately inserts the electronic component into the corresponding position according to the plug-in position requirement through the cooperation of the belt pulley 10, the external thread 9, the ball spline 12 and the reciprocating ball way 2.

[0043] After the plug-in is completed, the air hole 4 stops the negative pressure supply, the suction nozzle 606 releases the electronic component, the clamping jaw 602 is opened, the ZR shaft 1 moves upward, and the next clamping operation is prepared.

[0044] In the whole working process, the components work cooperatively, the suction nozzle 606 and the clamping jaw 602 are combined through the negative pressure adsorption and the mechanical clamping, the clamping and plug-in operation of the special-shaped electronic component with different shapes, sizes and materials can be adapted, the damage to the electronic component is effectively avoided, and the production efficiency and the product quality are improved.

[0045] Although the embodiments of the utility model have been shown and described, the specific embodiments are only the explanation of the utility model, and are not the limitation of the utility model, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way, the person skilled in the art can make the modification, replacement and change without the creative contribution after reading the specification without departing from the principles and purposes of the utility model, but as long as in the claim range of the utility model, it is protected by the patent law.
