Description

Technical Field

[0001] The utility model relates to the field of chip placement machine equipment, in particular to a split type suction nozzle. Background Art

[0002] The placement machine is a core equipment on the production line of the SMT industry. It is mainly used to assemble electronic components onto circuit boards. The placement machine is a product of the combination of computer control technology and electromechanical optics. It is a precision working robot. It gives full play to the high-tech achievements of modern precision machinery, mechatronics, optoelectronics, and computer control technology to achieve high-speed, high-precision, and intelligent electronic assembly manufacturing equipment. It can quickly and accurately place various electronic components on the specified pad position on the circuit board through functions such as picking, displacement, alignment, and placement. The placement machine is generally located behind the solder paste printer of the entire SMT production line.

[0003] Among them, the existing nozzles of the placement machine are usually one-piece, and the nozzle head part and the mounting position are integrally processed and formed. On the one hand, the nozzle head and the machine body are integrally processed and formed, which is difficult to process and has high processing costs. On the other hand, the nozzle head of the placement machine is a consumable material, and the nozzle head part is prone to wear, breakage and deformation after long-term use. When the nozzle head part or the connection between the nozzle head and the machine body is damaged, the entire nozzle must be replaced because the existing nozzle of the placement machine is a one-piece structure, which causes the entire nozzle to be scrapped. In addition, after the nozzle head is damaged, the entire operation of replacing the nozzle is cumbersome, which reduces work efficiency.

[0004] Therefore, how to design a split suction nozzle that is easy to replace and reduces the cost of nozzle replacement is a technical problem that needs to be solved. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a split suction nozzle, which solves the problem that the nozzle head of the existing one-piece suction nozzle is easily damaged and the entire suction nozzle must be replaced after damage, which has high use costs and cumbersome replacement procedures.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a nozzle and a seat magnetically connected to the nozzle; a limit assembly is provided at the end of the nozzle connection end, and the limit assembly includes a limit block in the shape of a letter "I" and a connecting block connecting the limit block and the nozzle; a connecting groove is provided in the connection end of the seat, and a through hole matching the shape and size of the limit block is provided on the surface of the end, and the through hole is connected to the connecting groove; a mounting groove matching the shape and size of the limit block is also provided on the inner wall of the bottom surface of the connecting groove, and the setting direction of the mounting groove is perpendicular to the setting direction of the through hole; a magnetic attraction component 1 is also provided in the mounting groove, and magnetic attraction components 2 magnetically connected to the magnetic attraction components are provided at the positions of the two ends of the limit block corresponding to the magnetic attraction component 1.

[0007] Furthermore, the width of the through hole is greater than the outer diameter of the connecting block.

[0008] Furthermore, the height of the connecting groove is greater than the height of the limit stopper.

[0009] Furthermore, arc-shaped clamping blocks that match each other are symmetrically arranged on both sides of the corresponding through holes on the end surface of the seat connection end, and a hole matching the outer diameter of the connection block is formed in the middle after the two arc-shaped clamping blocks are connected.

[0010] Furthermore, a buckle is provided at one end of the arc-shaped clamping block, and a clamping slot matched with the buckle is provided at the other end; the buckles and the clamping slots of the two arc-shaped clamping blocks are clamped and connected to each other.

[0011] Furthermore, the two arc-shaped clamping blocks are slidably arranged on the end surface of the seat connection end.

[0012] The utility model has the following beneficial effects:

[0013] 1- The utility model divides the suction nozzle into a nozzle head and a seat, and the nozzle head and the seat are detachably connected. When the nozzle head is damaged, the connection between the nozzle head limit block and the connecting groove is released by rotating the nozzle head, and the nozzle head is pulled out downward, thereby greatly reducing the processing cost and replacement cost of the iron sheet machine suction nozzle and simplifying the nozzle replacement steps.

[0022] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0023] See also Figure 1-5 As shown, the solution includes a nozzle head 1 and a seat 2 magnetically connected to the nozzle head 1;

[0024] A limit assembly 11 is provided at the end of the connection end of the nozzle head 1, and the limit assembly 11 includes a limit block 111 in the shape of a letter "I" and a connecting block 112 connecting the limit block 111 and the nozzle head 1. A connecting groove 21 is provided in the connection end of the seat 2, and a through hole 22 matching the shape and size of the limit block 111 is provided on the surface of the end, and the through hole 22 is communicated with the connecting groove 21. A mounting groove 23 matching the shape and size of the limit block 111 is also provided on the inner wall of the bottom surface of the connecting groove 21, and the setting direction of the mounting groove 23 is perpendicular to the setting direction of the through hole 22; a magnetic suction piece 231 is also provided in the mounting groove 23, and a magnetic suction piece 2 1111 connected to the magnetic suction piece 231 is provided at the positions of the two ends of the limit block 111 corresponding to the magnetic suction piece 231.

[0025] The width of the through hole 22 is greater than the outer diameter of the connecting block 112 , so that the connecting block 112 can rotate in the through hole 22 easily.

[0026] The height of the connecting groove 21 is greater than the height of the limiting block 111 , so that the limiting block 111 can be easily rotated in the connecting groove 21 after being moved out of the installation groove 23 .

[0027] On the connecting end surface of the seat 2, arc-shaped clamping blocks 24 are symmetrically arranged on both sides of the corresponding through hole 22, and a hole matching the outer diameter of the connecting block 112 is formed in the middle after the two arc-shaped clamping blocks 24 are connected. When the nozzle 1 and the seat 2 are connected, the arc-shaped clamping blocks 24 are pushed to connect the two arc-shaped clamping blocks 24 to each other, and the two arc-shaped clamping blocks 24 embrace the connecting block 112 to prevent the nozzle 1 from shaking left and right, thereby strengthening the connection between the suction head and the seat 2.

[0028] A buckle 241 is provided at one end of the arc-shaped clamping block 24 , and a clamping slot 242 matching with the buckle 241 is provided at the other end; the buckles 241 and the clamping slots 242 of the two arc-shaped clamping blocks 24 are clamped and connected to each other.

[0029] The two arc-shaped clamping blocks 24 are slidably disposed on the end surface of the connecting end of the seat 2 .

[0030] The working principle is roughly as follows:

[0031] During installation, align the limit stop 111 with the through hole 22, and insert the limit stop 111 into the connecting groove 21 through the through hole 22 until the limit stop 111 and the connecting block 112 are inserted into the seat 2. At this time, rotate the nozzle head 1 to the left or right, and the limit stop 111 rotates 90° in the connecting groove 21 so that the limit stop 111 moves to a position corresponding to the mounting groove 23. At this time, let go, and the limit stop 111 is stuck in the mounting groove 23. Under the action of magnetic suction component 1 231 and magnetic suction component 2 (magnetic suction component 1 231 and magnetic suction component 2 also assist the connection between the limit stop 111 and the mounting groove 23), the limit stop 111 is tightly connected to the mounting groove 23, so that the nozzle head 1 and the seat 2 are connected as a whole.

[0032] When disassembling, push the nozzle head 1 toward the seat 2 to move the limit stopper 111 upward to release the connection between the limit stopper 111 and the mounting groove 23, rotate 90° to the left or right to align the limit stopper 111 with the through hole 22, and pull the nozzle head 1 downward to complete the disassembly.

[0033] The above description is only a specific implementation method of the utility model, and does not limit the patent scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the utility model.
