[0002] The chip mounter, also known as the "mounting machine" or "surface mount system", is a device that is placed after the dispensing machine or screen printer in the production line. It is a device that accurately places surface mount components on the PCB pads by moving the mounting head. It is divided into manual and fully automatic types. It is a device used to place components at high speed and high precision. It is the most critical and complex equipment in the entire SMI production. The chip mounter is a chip mounter used in the production of SMT. Now, the chip mounter has developed from the early low-speed mechanical chip mounter to the high-speed optical centering chip mounter, and has developed towards multi-functional, flexible connection modularization. The chip mounter nozzle is an indispensable device in the work of the chip mounter.

[0003] In the prior art, Chinese utility model disclosure specification CN218587564U discloses a nozzle for a placement machine, and designs a nozzle installation structure for the placement machine. When the nozzle is inserted into the connecting rod, the positioning column is inserted into the interior of the positioning groove, and the spring pushes the limit block to be inserted into the interior of the limit groove to fix the positioning column, thereby completing the installation of the nozzle.

[0004] However, the existing device needs to move the connection plate to drive the limit block to move during installation and removal. Because the connection plate is too close to the nozzle and the connection plate itself is small, it is not convenient to move it, which makes removal inconvenient. Therefore, a fixing structure that is easier to install and remove the nozzle is designed to solve the above problems. Utility Model Content

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

[0025] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0026] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0028] When chip packaging, it is necessary to use a chip mounter to mount the chip on the substrate. There are two main ways to combine the chip and the substrate: gluing and welding. When using the eutectic chip mounting process with solder welding, the surface of the chip and the substrate must first be metallized. After the chip is mounted, a metal connection layer is formed between the chip and the substrate, which has high bonding strength and high thermal conductivity. It has been widely promoted in the field of semiconductor packaging. The nozzle of the chip mounter is an indispensable device in the work of the chip mounter.

[0029] In the related art, when installing the nozzle in the existing device, the positioning rod needs to be inserted into the positioning hole, and when the limiting groove is aligned with the limiting block, the connecting plate spring is released to push the limiting block into the limiting groove to fix the positioning rod, thereby completing the installation of the nozzle. However, when disassembling the existing device, the connecting plate is small in size and is not convenient to move.

[0030] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a new type of nozzle for a placement machine. When the nozzle 13 needs to be installed, first insert the bottom of the nozzle 13 into the interior of the connecting tube 12. When moving downward, the bottom of the clamping ring 21 contacts the top of the vertical rod 23 and squeezes the vertical rod 23 to rotate. When the vertical rod 23 rotates, the torsion spring 24 is squeezed and compressed. After the top of the vertical rod 23 is offset from the clamping ring 21, the torsion spring 24 rebounds and pushes the vertical rod 23 to rotate and reset, and is fixed with the clamping ring 21. When disassembly is required, only the push plate 25 needs to be pressed to rotate the vertical rod 23 to release the fixation of the clamping ring 21, and the nozzle 13 can be pulled out from the interior of the connecting tube 12.

[0031] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Combination Figure 1-Figure 3 The embodiment of the present application provides a new type of placement machine nozzle, including: a box body 11, a connecting tube 12 is arranged on the top of the box body 11; the bottom of the nozzle 13 is inserted into the interior of the connecting tube 12; a fixing component 2 is arranged on the top of the connecting tube 12, and the fixing component 2 includes: a clamping ring 21 fixedly sleeved on the outer wall of the nozzle 13; a ring body 22 is arranged on the top of the connecting tube 12; a vertical rod 23 is arranged on the top of the connecting tube 12, and the vertical rod 23 is rotatably connected to the top of the connecting tube 12; a torsion spring 24 is arranged at the connection between the vertical rod 23 and the connecting tube 12, and is used to push the vertical rod 23 to rotate.

[0033] Specifically, the bottom of the ring body 22 is welded and fixed to the top of the connecting tube 12, the clamping ring 21 and the outer wall of the suction nozzle 13 are also connected by the clamping ring, and the bottom of the vertical rod 23 is hinged to the connecting tube 12 and can rotate. The torsion spring 24 is fixed to the connecting tube 12 and the vertical rod 23 by means of the clamping ring. The fixing method of the clamping ring belongs to the existing well-known technology and will not be described in detail here.

[0034] When the nozzle is used, it is necessary to install the nozzle. First, insert the bottom of the nozzle 13 into the connecting tube 12. When moving downward, the bottom of the clamp ring 21 contacts the top of the vertical rod 23 and squeezes the vertical rod 23 to rotate. When the vertical rod 23 rotates, the torsion spring 24 is compressed until the top of the vertical rod 23 is offset from the clamp ring 21. The torsion spring 24 rebounds and pushes the vertical rod 23 to rotate and reset, and is fixed with the clamp ring 21.

[0035] In some embodiments, the bottom of the clamping ring 21 is designed to be inclined, and the inclination angle is consistent with the inclination angle of the top of the vertical rod 23.

[0036] When in use, the inclined design of the bottom of the clamping ring 21 can reduce the friction force when it contacts the top of the vertical rod 23.

[0037] In some embodiments, the fixing assembly 2 further includes: a push plate 25 disposed on an outer side wall of the vertical rod 23 .

[0038] When in use, the push plate 25 can easily push the upright pole 23 to rotate, making disassembly more convenient.

[0039] In some embodiments, the top of the push plate 25 is designed as an arc-shaped groove.

[0040] When in use, the groove design prevents fingers from sliding easily when placed on the push plate.

[0041] In some embodiments, the fixing assembly 2 further includes: a sponge pad 26 disposed in the top arc groove of the push plate 25 .

[0042] During use, the provision of the sponge pad 26 can provide a higher sense of comfort when pressing the push plate 25 .

[0043] In some embodiments, the fixing assembly 2 further includes: a ball 27 rotatably disposed on the top inclined surface of the vertical rod 23 .

[0044] When in use, the provision of the ball 27 can reduce the friction force when the clamping ring 21 contacts the top of the vertical rod 23.

[0045] In some embodiments, the fixing assembly 2 further includes: a rubber pad 28 disposed on the top of the clamping ring 21 .

[0046] When in use, the design of the rubber pad 28 can increase the friction force after the vertical rod 23 and the clamping ring 21 are engaged, thereby preventing them from falling off easily.

[0047] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.
