Description

Technical Field

[0001] The utility model belongs to the technical field of chip mounters, and particularly relates to an integrated new suction nozzle rod. Background Art

[0002] A chip mounter, also known as a "chip placer" or "surface mount system" (Surface Mount System), is a key device in a production line. The chip mounter is configured after a dispensing machine or a screen printer. It mainly places surface mount components accurately on the pads of a PCB (printed circuit board) by moving a placement head. It usually consists of a mechanical system, a PCB transmission and positioning system, a robotic arm (i.e., the placement head), a vision positioning system, and a micro control system. When working, the PCB transmission and positioning system transports the PCB to the placement area and fixes it. The placement head sucks the components through a suction nozzle and accurately places them at the designated positions on the PCB with the assistance of the vision system.

[0003] During the production process of the suction nozzle rods used in traditional chip mounters, most of them are produced separately by different manufacturers, and then the produced parts are transported to the factories that need to use them for assembly. In this process, the cost consumed by users is relatively high. Moreover, during the assembly process, the working time of the staff will be increased, reducing the working efficiency of the staff. In view of this, we propose an integrated new suction nozzle rod. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an integrated new suction nozzle rod to solve the problems raised in the above background art.

[0005] In view of this, the utility model provides an integrated new suction nozzle rod, including:

[0006] A first suction nozzle rod and a threaded rod. The top end of the first suction nozzle rod is fixedly connected with the threaded rod, the top end of the threaded rod is fixedly connected with a second suction nozzle rod, and a flange is fixedly connected to the peripheral side of the first suction nozzle rod;

[0007] A chute. The chute is opened in the second suction nozzle rod and communicates with the outside. Two symmetrically arranged limiting grooves are opened on the inner wall of the chute. A third suction nozzle rod is slidably connected in the chute, and the top end of the third suction nozzle rod extends to the outside. Two symmetrically arranged first limiting blocks are fixedly connected to the peripheral side of the third suction nozzle rod, and one ends of the two first limiting blocks respectively extend into the two limiting grooves and are slidably connected with the two limiting grooves. A return spring fixed to the bottom surface of the inner wall of the chute is fixedly connected to the bottom end of the third suction nozzle rod. A fixing block is fixedly connected to the peripheral side of the third suction nozzle rod, and the fixing block is located outside;

[0008] A through groove. The through groove is opened in the first suction nozzle rod, the threaded rod, and the second suction nozzle rod and communicates with the inner cavity of the third suction nozzle rod;

[0009] An air extraction hole is provided on the peripheral side of the first suction nozzle rod and is communicated with the through groove;

[0010] A second limiting block is fixedly connected to the peripheral side of the fixed block and is located above the fixed block. A suction nozzle head that is inserted and matched with the fixed block is provided on the second limiting block;

[0011] A limiting assembly is located on the fixed block and is used to limit the suction nozzle head.

[0012] Based on the above structure, by setting the first suction nozzle rod, the threaded rod, the second suction nozzle rod and the flange, it is ensured that when the factory assembles the overall device normally, it is not necessary to produce separately, nor to consume a lot of economy for transportation, reducing the economic expenditure of users. By setting the chute, the third suction nozzle rod and the suction nozzle head, it is ensured that the suction nozzle head can be inserted into the top end of the third suction nozzle rod, and when the top end of the suction nozzle head abuts against the patch, the third suction nozzle rod can slide in the chute, reducing the impact force generated by the contact between the top end of the suction nozzle head and the patch and preventing the patch from being damaged. By setting the third suction nozzle rod and the suction nozzle head, and by setting the limiting assembly and the second limiting block, it is ensured that the limiting assembly can limit the suction nozzle head on the second limiting block, preventing the suction nozzle head from falling off the fixed block when the overall device is in use. By setting the limiting groove, the first limiting block and the fixed block, it is ensured that when the third suction nozzle rod slides in the chute, the two first limiting blocks can slide in the two limiting grooves respectively. When the two first limiting blocks slide, the two first limiting blocks and the fixed block will play a role in limiting the third suction nozzle rod, preventing the third suction nozzle rod from moving from the chute to the outside. By setting the return spring, it is ensured that when the overall device is not working, the third suction nozzle rod will be reset under the action of the rebounding force of the return spring. By setting the through groove and the air extraction hole, it is ensured that the air extraction assembly on the mounter can extract air from the through groove through the air extraction hole, and the through groove can extract air through the third suction nozzle rod and the suction nozzle head.

[0013] In the above technical solution, further, the limiting assembly includes:

[0014] Two first elastic pieces are respectively arranged on both sides of the fixed block, and the two first elastic pieces are respectively attached to both sides of the second limiting block. Two second elastic pieces are respectively fixedly connected to the tops of the two first elastic pieces, and the two second elastic pieces are respectively attached to both sides of the lower half of the suction nozzle head. Two bolts are threadedly connected to the two first elastic pieces, and one end of each of the two bolts penetrates through the fixed block and extends into the fixed block to be threadedly connected with the fixed block.

[0015] In this technical solution, it is ensured that the suction nozzle head can be limited on the second limiting block.

[0016] In the above technical solution, further, the second elastic piece is in a "V" shape.

[0017] In this technical solution, it is ensured that the two second elastic pieces can limit the nozzle head on the second limiting block.

[0018] In the above technical solution, further, the lower half of the nozzle head is in a polygonal structure.

[0019] In this technical solution, it is ensured that the lower half of the nozzle head can be limited by the two second elastic pieces.

[0020] In the above technical solution, further, the inner cavity of the third nozzle rod is communicated with the inner cavity of the nozzle head.

[0021] In this technical solution, it is ensured that when the user activates the air extraction component on the mounter, the air extraction component can extract air from the through groove through the air extraction hole, so that the through groove can suck the patch through the third nozzle rod and the nozzle head.

[0022] In the above technical solution, further, the first nozzle rod, the threaded rod, the second nozzle rod and the flange are in an integral structure.

[0023] In this technical solution, it is ensured that when the manufacturer produces the overall device, the production cost can be reduced.

[0024] The beneficial effects of the present utility model are:

[0025] This integrated new suction nozzle rod, through the first suction nozzle rod, threaded rod, second suction nozzle rod and flange plate set, ensures that when the factory installs the normal overall device, it does not need to be produced separately, nor does it need to consume a lot of economy for transportation, reducing the economic expenditure of users. Through the chute, third suction nozzle rod and suction nozzle head set, it ensures that the suction nozzle head can be inserted into the top of the third suction nozzle rod, and when the top of the suction nozzle head abuts against the patch, the third suction nozzle rod can slide in the chute, reducing the impact force generated by the contact between the top of the suction nozzle head and the patch and preventing the patch from being damaged. Through the third suction nozzle rod and suction nozzle head set, and through the limit component and the second limit block set, it ensures that the limit component can limit the suction nozzle head on the second limit block, preventing the suction nozzle head from falling off the fixed block when the overall device is in use. Through the limit groove, first limit block and fixed block set, it ensures that when the third suction nozzle rod slides in the chute, the two first limit blocks can slide in the two limit grooves respectively. When the two first limit blocks slide, the two first limit blocks and the fixed block will play a role in limiting the third suction nozzle rod, preventing the third suction nozzle rod from moving from the chute to the outside. Through the reset spring set, it ensures that when the overall device is not working, the third suction nozzle rod will be reset under the action of the rebound force of the reset spring. Through the through groove and air extraction hole set, it ensures that the air extraction component on the chip mounter can extract air from the through groove through the air extraction hole, and let the through groove extract air through the third suction nozzle rod and the suction nozzle head, solving the problem that most of the suction nozzle rods used in traditional chip mounters are produced separately by different manufacturers, and then the produced parts are transported to the factory where they are needed for assembly. In this process, the cost consumption of users is relatively high, and during the assembly process, the working time of the staff will be increased, reducing the working efficiency of the staff.
