Description

Technical Field

[0001] The utility model belongs to the technical field of chip mounters, and particularly relates to a nozzle rod with high concentricity that is convenient for installation and disassembly. Background Technique

[0002] In a production line, a chip mounter is configured after a dispensing machine or a screen printer. It is a device that accurately places surface-mounted components on PCB pads by moving a mounting head. The nozzle rod is a key component on the chip mounter, and its main function is to support and fix the nozzle to ensure that the chip mounter can normally and stably perform the operations of sucking and placing components.

[0003] Most nozzle rods have some disadvantages during use. For example, the installation process of the nozzle rod and the nozzle is relatively complex. Especially in a production environment where the nozzle or the nozzle rod needs to be frequently replaced, this complexity will significantly reduce work efficiency and increase operation time and costs. In view of this, we propose a nozzle rod with high concentricity that is convenient for installation and disassembly. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a nozzle rod with high concentricity that is convenient for installation and disassembly to solve the problems raised in the above background technique.

[0005] In view of this, the utility model provides a nozzle rod with high concentricity that is convenient for installation and disassembly, including:

[0006] A suction rod body, a sliding groove is opened at the top of the suction rod body, a connecting rod is slidably installed in the sliding groove, a spring fixed to the inner wall of the sliding groove is fixedly installed at the lower end of the connecting rod, the upper end of the connecting rod penetrates through the sliding groove and extends to the outside and is fixedly installed with a first fixing block, a second fixing block is fixedly installed on the connecting rod and above the first fixing block, and the suction rod body is communicated with the connecting rod;

[0007] Two elastic pieces, the two elastic pieces are respectively fixed to both sides of the first fixing block by two screws, limiting grooves are opened on both sides of the second fixing block, and the elastic pieces are inserted and matched with the corresponding limiting grooves;

[0008] A limiting component, which is located on the suction rod body and is used to limit the sliding of the connecting rod;

[0009] A nozzle body, the nozzle body is inserted and installed at the upper end of the second fixing block and between the two elastic pieces, the nozzle body is in close contact with the two elastic pieces, an air outlet pipe is fixedly installed at the top of the nozzle body, and the connecting rod is communicated with the nozzle body and the air outlet pipe.

[0010] In this technical solution, when it is necessary to disassemble the nozzle body, the operator pinches the air outlet pipe and pulls it upward. The air outlet pipe drives the nozzle body to move upward. Under the action of the elastic force, the nozzle body will first squeeze the two elastic pieces to move in the two limit slots respectively and move away from each other. When the nozzle body disengages from between the two elastic pieces, under the action of the elastic force, the two elastic pieces move in the two limit slots respectively and approach each other, and then the two elastic pieces return to their original positions. When it is necessary to install the nozzle body, first insert the nozzle body onto the connecting rod. Under the action of the elastic force, the nozzle body will squeeze the two elastic pieces to move in the two limit slots respectively and move away from each other. When the nozzle body is inserted to the appropriate position, under the action of the elastic force, the two elastic pieces move in the two limit slots respectively and approach each other, and then the two elastic pieces return to their original positions. The two elastic pieces can clamp both sides of the nozzle body, so that the position of the nozzle body is fixed and will not move randomly, which is convenient for disassembling and installing the nozzle body and the air outlet pipe. At the same time, no tools are required and the operation is simple;

[0011] When it is necessary to disassemble the two elastic pieces, the operator uses a screwdriver to remove the two screws, and then the two elastic pieces can be disassembled from both sides of the first fixing block. When it is necessary to install the two elastic pieces, the operator uses a screwdriver to fix the two elastic pieces to both sides of the first fixing block through the two screws, which achieves the convenience of disassembling and installing the two elastic pieces and the operation is simple;

[0012] When the connecting rod is squeezed, the connecting rod will slide towards the spring and squeeze the spring to contract. Through the set limit component, the stability of the connecting rod during sliding is ensured. When the connecting rod is no longer squeezed, under the action of the spring rebound force, the connecting rod will slide away from the spring.

[0013] In the above technical solution, further, the limit component includes:

[0014] Two grooves, both of the two grooves are opened on the suction rod body and are located on both sides of the sliding groove. Both of the two grooves are communicated with the sliding groove. A limit post fixed to the connecting rod is slidably installed in the groove.

[0015] In this technical solution, when the connecting rod slides, the two limit posts slide in the two grooves respectively, so that the connecting rod can only move up and down and cannot move in other directions.

[0016] In the above technical solution, further, the nozzle body has a polygonal structure, the width of the elastic piece is the same as the width of the limit slot, and the upper cross section of the elastic piece is V-shaped.

[0017] In this technical solution, it is ensured that the nozzle body can be clamped by two elastic pieces, and at the same time, the nozzle body will not be displaced. It is ensured that the elastic pieces cannot move left and right in the limiting grooves. When the nozzle body presses the upper ends of the two elastic pieces, the two elastic pieces will be displaced and move away from each other.

[0018] In the above technical solution, further, the outer diameter dimension of the connecting rod is the same as the diameter of the sliding groove.

[0019] In this technical solution, the sealing performance between the connecting rod and the sliding groove is ensured to prevent gas from leaking to the outside through the sliding groove.

[0020] In the above technical solution, further, the diameter of the limiting post is the same as the size of the groove.

[0021] In this technical solution, it is ensured that the limiting post can only move up and down in the groove, and further ensure that the connecting rod can only slide up and down.

[0022] The beneficial effects of the present utility model are:

[0023] 1. For this high-concentricity nozzle rod that is convenient for installation and disassembly, when a person pinches the air outlet pipe and pulls it upward, the air outlet pipe drives the nozzle body to move upward. Under the action of the elastic force, the nozzle body will first press the two elastic pieces to move in the two limiting grooves and move away from each other. When the nozzle body disengages from between the two elastic pieces, under the action of the elastic force, the two elastic pieces move in the two limiting grooves and approach each other, and then the two elastic pieces return to their original positions;

[0024] First, insert the nozzle body onto the connecting rod. Under the action of the elastic force, the nozzle body will press the two elastic pieces to move in the two limiting grooves and move away from each other. When the nozzle body is inserted to the appropriate position, under the action of the elastic force, the two elastic pieces move in the two limiting grooves and approach each other, and then the two elastic pieces return to their original positions. The two elastic pieces can clamp both sides of the nozzle body, fixing the position of the nozzle body and preventing it from being displaced randomly, facilitating the disassembly and installation of the nozzle body and the air outlet pipe. At the same time, no tools are required, and the operation is simple.

[0025] 2.
