Description

Technical Field

[0001] This utility model relates to the field of suction nozzle technology, specifically to a high-efficiency protective suction nozzle assembly. Background Technology

[0002] With the integration of surface mount components, most circuit boards use surface mount components. Because surface mount components are simple and easy to use, but small in size and numerous, they are usually mounted by pick-and-place machines. The pick-and-place machine uses negative pressure to attract the components to the nozzle, and then sprays air to place the components in the correct position.

[0003] However, current nozzles have a simple structure and are generally one-piece designs. During adsorption, they are in prolonged contact with the mounted components, which can easily cause wear on the bottom of the nozzle. If the surface becomes rough or uneven, it will affect the adsorption quality. In addition, to provide a cushioning effect, current nozzles are equipped with compression springs. However, these compression springs are inconvenient to remove, and after prolonged use, their elasticity will decrease, thus affecting the subsequent cushioning effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-efficiency protective nozzle assembly with a quick-release sealing ring, which increases the protective effect and avoids damage to the mounting components. The compression spring can also be disassembled, thus solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a high-efficiency protective suction nozzle assembly, including a suction nozzle rod, a suction nozzle head, and a sealing ring. The suction nozzle head is sleeved on one end of the suction nozzle rod, and the end of the suction nozzle head away from the suction nozzle rod is recessed to form a positioning channel. The center of the sealing ring protrudes to form a positioning part, which is inserted into the positioning channel. The center of the positioning part is provided with an air suction hole communicating with the positioning channel. The outer ring surface of the sealing ring is provided with an annular limiting groove. Clamping plates are provided on both sides of the sealing ring. The inner side of the clamping plate protrudes to form a limiting part, which is inserted into the annular limiting groove. Spring pieces are installed on the outer side of the clamping plates. An elastic mechanism is installed between the suction nozzle head and the suction nozzle rod.

[0006] As a preferred technical solution, the elastic mechanism includes a first connecting ring, a second connecting ring, a first connecting sleeve, a second connecting sleeve, and a compression spring. The middle part of the suction rod protrudes to form an annular connecting part. The first connecting ring is installed on the annular connecting part, and the second connecting ring is installed at one end of the suction head.

[0007] The first connecting sleeve is threaded onto the first connecting ring, the second connecting sleeve is threaded onto the second connecting ring, the compression spring is sleeved on the suction rod, one end of the compression spring is installed on the first connecting sleeve, the other end is installed on the second connecting sleeve, and the other end of the spring is bent and fixed on the second connecting sleeve.

[0008] As a preferred technical solution, the sealing ring is made of rubber material, and both the clamping plate and the limiting part are arranged in an arc shape. The degree of arc of the clamping plate and the limiting part matches the degree of arc of the sealing ring. The inner side of the clamping plate is in contact with the outer ring surface of the sealing ring, and the inner side of the limiting part is in contact with the inner ring surface of the annular limiting groove.

[0009] As a preferred technical solution, the diameter of the positioning part matches the inner diameter of the positioning channel, and multiple annular grooves are provided on the inner ring surface of the positioning channel.

[0010] As a preferred technical solution, the first connecting ring, the second connecting ring, the first connecting sleeve, and the second connecting sleeve are all made of engineering plastic materials.

[0011] As a preferred technical solution, the spring is a metal spring.

[0012] The beneficial effects of this utility model are: the utility model has a simple structure and is equipped with a sealing ring. The sealing ring contacts the mounting element, which prevents the mounting element from being crushed. After the spring is opened outward, the sealing ring can be quickly replaced. The sealing ring and the nozzle head are matched by the protruding positioning part and the recessed positioning channel, which increases the sealing between the two. The compression spring is installed on the first connecting sleeve and the second connecting sleeve, so that the compression spring can be removed from the nozzle rod and replaced to ensure the subsequent buffering effect.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a high-efficiency protective suction nozzle assembly, including a suction nozzle rod 1, a suction nozzle head 2, and a sealing ring 3. The suction nozzle head 2 is sleeved on one end of the suction nozzle rod 1, and the end of the suction nozzle head 2 away from the suction nozzle rod 1 is recessed to form a positioning channel 13. A positioning part 14 is protruding from the center of the sealing ring 3 and is inserted into the positioning channel 13. An air suction hole communicating with the positioning channel 13 is provided at the center of the positioning part 14. An annular limiting groove 4 is provided on the outer ring surface of the sealing ring 3. Clamping plates 6 are provided on both sides of the sealing ring 3. A limiting part 5 is protruding from the inner side of the clamping plate 6 and is inserted into the annular limiting groove 4. Spring pieces 7 are installed on the outer side of the clamping plate 6. An elastic mechanism is installed between the suction nozzle head 2 and the suction nozzle rod 1.

[0023] In this embodiment, the elastic mechanism includes a first connecting ring 12, a second connecting ring 11, a first connecting sleeve 10, a second connecting sleeve 8, and a compression spring 9. The middle part of the suction rod 1 protrudes to form an annular connecting part. The first connecting ring 12 is installed on the annular connecting part, and the second connecting ring 11 is installed on one end of the suction head 2.

[0024] The first connecting sleeve 10 is threaded to the first connecting ring 12, the second connecting sleeve 8 is threaded to the second connecting ring 11, the compression spring 9 is sleeved on the suction rod 1, one end of the compression spring 9 is installed on the first connecting sleeve 10, and the other end is installed on the second connecting sleeve 8, and the other end of the spring piece 7 is bent and fixed on the second connecting sleeve 8.

[0025] The compression spring is installed on the first connecting sleeve and the second connecting sleeve. The first connecting sleeve is threaded to the first connecting ring, and the second connecting sleeve is threaded to the second connecting ring. The threaded connection facilitates disassembly and assembly.

[0026] In this embodiment, the sealing ring 3 is made of rubber material, and both the clamping plate 6 and the limiting part 5 are arc-shaped. The degree of arc of the clamping plate 6 and the limiting part 5 matches the degree of arc of the sealing ring 3. The inner surface of the clamping plate 6 is in contact with the outer surface of the sealing ring 3, and the inner surface of the limiting part 5 is in contact with the inner surface of the annular limiting groove 4. This ensures that the limiting part and the clamping plate can match the sealing ring, increasing the stability after clamping. The bottom surface of the clamping plate is higher than the bottom surface of the sealing ring, which avoids contact between the clamping plate and the mounting component during adsorption.

[0027] In this embodiment, the diameter of the positioning part 14 matches the inner diameter of the positioning channel 13, and the inner ring surface of the positioning channel 13 is provided with multiple annular grooves. The annular grooves increase the sealing effect between the positioning part and the positioning channel, which can better intercept gas.

[0028] In this embodiment, the first connecting ring 12, the second connecting ring 11, the first connecting sleeve 10, and the second connecting sleeve 8 are all made of engineering plastic materials, which reduces weight and cost.

[0029] In this embodiment, the spring is a metal spring, which allows for better positioning of the sealing ring.

[0030] During installation, pry the spring tab outwards. The movement of the spring tab moves the clamping plate and the limiting part. Then, insert the positioning part on the sealing ring into the positioning channel. After one end of the sealing ring contacts the nozzle head, release the spring tab. The spring tab's rebound will insert the limiting part into the annular limiting groove, thereby fixing the sealing ring. During the nozzle's descent, the sealing ring contacts the component below. The flexibility of the sealing ring prevents damage to the mounted component and increases safety.

[0031] During the descent of the nozzle head, once it comes into contact with the component being mounted, the nozzle head has an upward function and compresses the spring. The spring's rebound provides a buffering effect.

[0032] After prolonged use, the compression spring can be rotated to remove the first and second connecting sleeves from the first and second connecting rings. After the first connecting sleeve is detached from the first connecting ring, it moves downward along the nozzle rod. During the downward movement, it can push the nozzle head, allowing the compression spring and nozzle head to be replaced synchronously. If the nozzle head can be reused, it can be reattached to the nozzle rod, increasing the efficiency of disassembly and assembly.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
