Description

Technical Field

[0001] The utility model relates to the technical field of nozzle rod equipment, in particular to a nozzle rod of a placement machine. Background Art

[0002] The placement machine is also known as the "mounting machine" or "surface mount system". In the production line, it is configured after the dispensing machine or screen printing machine. It is a device that accurately places surface mount components on the PCB pads by moving the suction nozzle rod. It is divided into manual and fully automatic types.

[0003] However, in the prior art, the nozzle rods of some existing placement machines are relatively long. In order to reduce the bending and deviation of the nozzle rods after being installed on the placement machine, the nozzle rods are generally equipped with nozzle rod sleeves and installed on the placement machine together with the nozzle rods. In order to provide good support for the longer nozzle rods, the nozzle rod sleeves themselves are also relatively long. Since the nozzle rod sleeves are generally in an integrated state and lack measures for self-separation, when a certain part of the nozzle rod sleeve is worn out after long-term use, it is necessary to replace the entire nozzle rod sleeve, resulting in a waste of resources. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art: since the nozzle rod sleeve is generally in an integrated state and lacks self-separation measures, when it is worn in a certain place after long-term use, it needs to be replaced as a whole, resulting in a waste of resources.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the suction nozzle rod of the placement machine includes a lower suction nozzle rod sleeve, the inner surface of the lower suction nozzle rod sleeve is provided with a longitudinal groove, and the surface of the lower suction nozzle rod sleeve is provided with a transverse groove at one end of the longitudinal groove, the lower suction nozzle rod sleeve is inserted and connected with an upper suction nozzle rod sleeve, one end of the upper suction nozzle rod sleeve is fixedly connected with a clamping block, and the clamping block is respectively slidably connected and clamped with the longitudinal groove and the transverse groove, the upper suction nozzle rod sleeve is connected with a suction nozzle rod body, and one end of the suction nozzle rod body is threadedly connected to the lower suction nozzle rod sleeve.

[0006] As a preferred embodiment, an anti-slip bump is fixedly connected to the outer surface of the upper nozzle rod sleeve.

[0007] As a preferred embodiment, the outer surface of the upper nozzle rod sleeve is slidably connected to a movable disk, and one end of the movable disk is fixedly connected to a penetration rod, which is penetrated and engaged with the lower nozzle rod sleeve and the block.

[0008] As a preferred embodiment, a lifting block is fixedly connected to the outer surface of the movable disk.

[0009] As a preferred embodiment, a positioning post is fixedly connected to the outer surface of the upper nozzle rod sleeve, and the positioning post is engaged with the movable disk.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are:

[0011] The utility model can disengage the clamping block from the horizontal groove by rotating the upper suction nozzle rod sleeve, and then the clamping block can slide on the vertical groove, so that the upper suction nozzle rod sleeve can be pulled out from the lower suction nozzle rod sleeve, thereby realizing the rapid separation of the lower suction nozzle rod sleeve and the upper suction nozzle rod sleeve. When the lower suction nozzle rod sleeve or the upper suction nozzle rod sleeve is worn, they can be disassembled and separated for targeted replacement, thereby reducing waste of resources.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1

[0019] like Figure 1-3As shown, the utility model provides a technical solution: the nozzle rod of the placement machine includes a lower nozzle rod sleeve 1, the lower nozzle rod sleeve 1 and the upper nozzle rod sleeve 4 play a supporting role on the nozzle rod body 7, reducing the bending and deviation of the nozzle rod body 7 during use. A longitudinal groove 2 is provided on the inner surface of the lower nozzle rod sleeve 1, and a transverse groove 3 is provided on the surface of the lower nozzle rod sleeve 1 at one end of the longitudinal groove 2. The upper nozzle rod sleeve 4 is inserted and connected on the lower nozzle rod sleeve 1, and a clamping block 5 is fixedly connected to one end of the upper nozzle rod sleeve 4, and the clamping block 5 is respectively slidably connected and clamped with the longitudinal groove 2 and the transverse groove 3. Through the cooperation of the longitudinal groove 2 and the transverse groove 3, the clamping block 5 is allowed to move along When the longitudinal groove 2 slides to its bottom and engages with the transverse groove 3, the lower nozzle rod sleeve 1 and the upper nozzle rod sleeve 4 can be quickly and stably docked, which is convenient for the rapid disassembly and assembly of the lower nozzle rod sleeve 1 and the upper nozzle rod sleeve 4. The upper nozzle rod sleeve 4 is connected with a nozzle rod body 7, and one end of the nozzle rod body 7 is threadedly connected to the lower nozzle rod sleeve 1. When the nozzle rod body 7 is installed on the placement machine for normal use, the nozzle rod body 7 is evacuated by the vacuum pump on the placement machine to generate negative pressure at the nozzle rod body 7, thereby adsorbing and fixing the component to one end of the nozzle rod body 7, so that the placement machine can accurately place the component on the PCB pad by controlling the movement of the nozzle rod body 7.

[0020] Example 2

[0021] like Figure 1-3 As shown, the outer surface of the upper suction nozzle rod sleeve 4 is fixedly connected with an anti-skid protrusion 6. The setting of the anti-skid protrusion 6 increases the friction of the outer surface of the upper suction nozzle rod sleeve 4, and reduces the slipping when the upper suction nozzle rod sleeve 4 is rotated. The outer surface of the upper suction nozzle rod sleeve 4 is slidably connected with a movable disk 8, and one end of the movable disk 8 is fixedly connected with an insertion rod 9, which is connected to the lower suction nozzle rod sleeve 1 and the block 5 through the insertion rod 9. By sliding the movable disk 8 downward, the insertion rod 9 is inserted and engaged with the lower suction nozzle rod sleeve 1 and the block 5, which effectively improves the suction nozzle rod sleeve 4. The high block 5 is engaged with the transverse groove 3 to ensure stability. The outer surface of the movable disk 8 is fixedly connected with a lifting block 10. With the help of the lifting block 10, the movable disk 8 can be moved up and down manually. The outer surface of the upper suction nozzle rod sleeve 4 is fixedly connected with a positioning column 11, and the positioning column 11 is engaged with the movable disk 8. The engagement of the positioning column 11 with the movable disk 8 allows the movable disk 8 to be suspended in the air, effectively preventing the movable disk 8 from accidentally sliding down and affecting the operation when the lower suction nozzle rod sleeve 1 and the upper suction nozzle rod sleeve 4 are disassembled and assembled.

[0022] Working principle:

[0023] like Figure 1-3As shown, when the present invention is in use, when the lower nozzle rod sleeve 1 or the upper nozzle rod sleeve 4 is worn and needs to be replaced, the user first manually rotates the nozzle rod body 7 to remove it from the lower nozzle rod sleeve 1, and pulls it out from the lower nozzle rod sleeve 1 and the upper nozzle rod sleeve 4, and then pulls the lifting block 10 to move the movable disk 8 upward as a whole, so that the insertion rod 9 is disengaged from the connection between the lower nozzle rod sleeve 1 and the clamping block 5, and the movable disk 8 is engaged with the positioning clamping column 11, so that it is suspended in the air, and then the upper nozzle rod sleeve 4 is twisted and rotated by pinching the anti-slip protrusion 6 by hand, driving the clamping block 5 to move it out of the engagement at the horizontal groove 3, and allowing the clamping block 5 to move to the longitudinal groove 2, and then the upper nozzle rod sleeve 4 can be pulled out from the lower nozzle rod sleeve 1, separating them, which is convenient for users to carry out targeted replacement.

[0024] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
