[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] A porous plate picking and placing mechanism, comprising a U-shaped plate 1. Translation components 2 are arranged on the inner walls of both sides of the U-shaped plate 1. An L-shaped mounting plate 3 is arranged at the moving end of the translation component 2. An electric push rod 4 is fixedly installed at the inner top of the L-shaped mounting plate 3. One end of the telescopic end of the electric push rod 4 penetrates through the L-shaped mounting plate 3 and is fixedly connected to a lifting plate 5. A suction cup component 6 for adsorbing and picking and placing the porous plate is arranged at the bottom of the lifting plate 5. Buffer components 7 for absorbing the impact force generated by the moving end of the translation component 2 are respectively arranged on the inner walls of both sides of the U-shaped plate 1. By setting the buffer component 7 in the present utility model, the impact force generated during the movement of the translation block 203 can be buffered, avoiding damage to the mechanical structure caused by the impact of the translation block 203, which is beneficial to extending the service life of the device. At the same time, when the buffer component 7 buffers the translation block 203, the translation block 203 runs more stably, avoiding the situation that the adsorbed porous plate falls off and is damaged due to the generated impact force;

[0027] The buffer component 7 includes two groups of positioning sleeves 701. Both groups of positioning sleeves 701 are fixedly installed on the inner wall of one side of the U-shaped plate 1. Adjusting rods 702 are slidably inserted into the interiors of both groups of positioning sleeves 701. One end of both groups of adjusting rods 702 is fixedly connected to a butting plate 703. The other ends of both groups of adjusting rods 702 are respectively fixedly connected to buffer springs 704. One ends of both groups of buffer springs 704 are respectively fixedly connected to the inner wall of one side of both groups of positioning sleeves 701. The buffer spring 704 mainly absorbs and disperses the impact energy through its elastic characteristics. When subjected to impact or vibration, the buffer spring 704 will undergo elastic deformation, thereby absorbing and dispersing these energies. This way of elastic deformation enables the buffer spring 704 to release energy by restoring the deformation after absorbing the vibration energy, thereby achieving the buffering effect;

[0028] It further includes a damper 8. One end of the damper 8 is fixedly connected to the inner wall of one side of the U-shaped plate 1. The other end of the damper 8 is fixedly connected to one side of the butting plate 703. The damper 8 mainly absorbs the impact energy by generating damping and further damps the vibration. The damper 8 converts the impact and vibration energies into heat energy or other forms of energy through its internal structure and material characteristics, thereby effectively reducing mechanical vibration and impact. The damper 8 and the buffer spring 704 are complementary in absorbing impact and vibration;

[0029] A rubber pad 9 is fixedly adhered to one side side wall of the butting plate 703. Rubber rings 10 are respectively fixedly adhered to one ends of both groups of positioning sleeves 701. By setting the rubber pad 9 and the rubber rings 10, it is used to provide further buffering;

[0030] The translation component 2 includes a lead screw 201. The two ends of the lead screw 201 are respectively rotatably installed on the inner walls of both sides of the U-shaped plate 1. One end of the lead screw 201 penetrates through the U-shaped plate 1 and is connected to a driving motor 202. A translation block 203 is threadedly connected to the outer wall of the lead screw 201. The translation block 203 serves as the moving end of the translation component 2. An L-shaped mounting plate 3 is fixedly installed on one side wall of the translation block 203, and one side of the translation block 203 abuts against one side of the rubber pad 9. The output shaft of the driving motor 202 drives the lead screw 201 to rotate, so as to drive the translation block 203 to make a reciprocating motion along the axial direction of the lead screw 201;

[0031] It should be noted that the abutment described here refers to the situation where the translation block 203 abuts immediately after moving to one side of the rubber pad 9;

[0032] It further includes two groups of guide rods 11. The two groups of guide rods 11 are respectively slidably inserted into the interior of the translation block 203, and the two ends of the two groups of guide rods 11 are respectively fixedly connected to the inner walls of both sides of the U-shaped plate 1. By providing the guide rods 11, the function of limiting the translation block 203 is achieved, making the translation block 203 more stable during operation;

[0033] The driving motor 202 is fixedly installed on one side wall of the U-shaped plate 1. One end of the output shaft of the driving motor 202 is fixedly connected to one end of the lead screw 201. The driving motor 202 is set as a forward and reverse stepping motor;

[0034] The suction cup assembly 6 includes two groups of cavity boxes 601. The two groups of cavity boxes 601 are both fixedly installed on the top of the lifting plate 5. A plurality of logic valves 602 are fixedly connected to the bottom of the lifting plate 5. The tops of the plurality of logic valves 602 all penetrate through the lifting plate 5 and communicate with the interior of the cavity boxes 601. The bottoms of the plurality of logic valves 602 are all fixedly communicated with suction cups 603. A vacuum pump connecting pipe 604 is fixedly communicated with one side wall of each of the two groups of cavity boxes 601;

[0035] It is worth noting that through the logic valve 602, it is possible to avoid air leakage when adsorbing to the hole area of the product, resulting in the product being unable to be adsorbed, so as to effectively adsorb the perforated plate, and it can be applied to the picking and placing of perforated plates of different specifications and shapes, with strong versatility.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
