[0056] In the process of automated assembly of electronic products, there is a process of attaching foam or adhesive to product parts. The collection and attachment of adhesive or foam requires a nozzle. In the known related technologies, in order to prevent the nozzle from rigidly contacting the material, the assembly equipment connects the nozzle with a spring. After long-term use, the nozzle is prone to shaking relative to the assembly equipment, and the nozzle connection is unstable, resulting in low operating accuracy of the nozzle.

[0057] In view of the above situation, it is necessary to provide a suction nozzle with a stable structure and high operating accuracy.

[0058] The embodiment of the present application provides a suction nozzle, including a base, a connecting member, a suction head and an elastic member. The base includes an outer ring and an inner ring arranged coaxially, the outer ring is arranged around the inner ring, a receiving groove is formed between the inner ring and the outer ring, the inner ring is provided with a first slot, and the first slot axially penetrates the inner ring and the outer ring; the connecting member has a first channel axially penetrating through both ends of the connecting member, the connecting member includes a sliding portion, the sliding portion extends axially, and is at least partially located in the first slot, and the sliding portion can move axially relative to the inner ring; the suction head is connected to one end of the connecting member away from the inner ring, and a second channel is provided through the suction head, and the first slot, the first channel and the second channel are connected; the elastic member is sleeved on the inner ring and the sliding portion, one end of the elastic member is located in the receiving groove and connected to the base, and the other end of the elastic member is connected to the suction head.

[0059] In the above-mentioned nozzle, the base and the suction head are connected by an elastic member. During the relative movement between the base and the suction head, the base applies force to the suction head through the elastic member, thereby buffering and reducing the force applied by the suction head to the material to prevent the material from being crushed; the suction head and the base are connected by a connecting member, so that the first through groove, the first channel and the second channel can be connected, and the sliding part is limited by the first slot to only move axially relative to the inner ring, so that only relative movement in the axial direction occurs between the suction head and the base, that is, the suction head will not shake relative to the base, and the elastic member is sleeved on the inner ring and the sliding part, so that the first slot limits the elastic member by limiting the sliding part, so that the direction in which the elastic member undergoes elastic deformation can only be axial, and the elastic member cannot undergo elastic deformation other than the axial direction. When the suction head contacts the material and presses down the material, the base moves axially toward the suction head through the inner ring, and the elastic member is elastically compressed in the axial direction, the suction head is tightly fitted to the material, one end of the inner ring provides negative pressure and adsorbs the material to the suction head through the first slot, the first channel and the second channel. In this way, the suction head and the base will not shake relative to each other during the operation of the suction nozzle, the structure of the suction nozzle is stable, and the operation accuracy is high.

[0060] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0061] The embodiment of the present application provides an assembly device, including a transfer mechanism, a vacuum generator and a suction nozzle 100. Figures 1 to 3 , the vacuum generator is connected to one end of the inner ring 12 away from the connecting piece 20 to provide negative pressure to the first slot 101. The transfer mechanism connects the vacuum generator and the suction nozzle 100 to drive the suction nozzle 100 to move, so that the suction nozzle 100 can approach the material 200, move away from the material 200, or drive the material 200 to move. In detail, the vacuum generator provides negative pressure for the suction nozzle 100, and the transfer mechanism drives the suction nozzle 100 to absorb the material 200, and moves the material 200 to the product, so that the material 200 is mounted on the product. Among them, the assembly equipment is used to realize the automated assembly of electronic products. The product is an electronic product. The material 200 is mounting foam or mounting adhesive.

[0062] In some embodiments, see Figures 1 to 4 The suction nozzle 100 includes a base 10, a connecting member 20, a suction head 30 and an elastic member 40. The two ends of the elastic member 40 are respectively connected to the base 10 and the suction head 30, so that the base 10 and the suction head 30 can move relative to each other through the elastic deformation of the elastic member 40, and the base 10 and the suction head 30 can transmit force through the elastic member 40. Compared with the force transmitted by the rigid connection, the force transmitted through the elastic member 40 can play a role of buffering and shock absorption, and can prevent the suction head 30 from crushing the material 200 when pressing down the material 200. The suction head 30 is connected to the connecting member 20, and the base 10 can move relative to the connecting member 20 in the axial direction, which can limit the direction of relative movement between the base 10 and the suction head 30 to always be the axial direction, and prevent the suction head 30 from shaking relative to the base 10. In this way, when the transfer mechanism drives the suction head 30 to act on the material 200 through the base 10, the suction head 30 will not shake relative to the transfer mechanism. Driven by the transfer mechanism, the suction head 30 can accurately act on the material 200. Such a suction nozzle 100 is not easy to crush the material 200 during operation, has a stable structure and high operating accuracy.

[0063] In some embodiments, see Figures 1 to 5 The base 10 includes an outer ring 11 and an inner ring 12 which are coaxially arranged. The outer ring 11 is arranged around the inner ring 12, and a receiving groove 13 is formed between the inner ring 12 and the outer ring 11. The receiving groove 13 can receive the elastic member 40 sleeved on the inner ring 12 to protect the elastic member 40. Figure 3 and Figure 4 The inner ring 12 is provided with a first slot 101. The connecting member 20 includes a sliding portion 21. The sliding portion 21 extends in the axial direction. The sliding portion 21 is at least partially located in the first slot 101. The sliding portion 21 can move relative to the inner ring 12 in the axial direction. The suction head 30 is connected to the end of the connecting member 20 away from the inner ring 12, so that the connecting member 20 moves relative to the inner ring 12 through the sliding portion 21, thereby driving the suction head 30 to move relative to the base 10 in the axial direction. Please refer to Figure 4 The first slot 101 axially penetrates the inner ring 12 and the outer ring 11. The connecting member 20 has a first channel 201 axially penetrating both ends of the connecting member 20. Figure 7 The suction head 30 is provided with a second channel 301. The first slot 101, the first channel 201 and the second channel 301 are connected. Figure 1 and Figure 4, one end of the elastic member 40 is located in the receiving groove 13 and connected to the base 10, and the other end of the elastic member 40 is connected to the suction head 30. When the suction nozzle 100 is assembled, the base 10 and the suction head 30 are connected by the connecting member 20, and the elastic member 40 is sleeved on the inner ring 12 and the sliding part 21, so that the elastic expansion and contraction direction of the elastic member 40 is the same as the extension direction of the inner ring 12 and the sliding part 21, that is, the elastic member 40 is guided to expand and contract along the axial direction, and the elastic member 40 does not affect the connection between the first slot 101, the first channel 201 and the second channel 301. In addition, the elastic member 40 can be connected to the suction head 30 and the base 10 without being sleeved on the inner ring 12 and the sliding part 21.

[0064] When in use, the transfer mechanism drives the suction nozzle 100 and the vacuum generator to move toward the material 200. When the lower end of the suction head 30 contacts the material 200, the transfer mechanism drives the suction nozzle 100 to press down the material 200, so that the base 10 presses down the elastic member 40 axially, and the suction head 30 is in close contact with the material 200. At the same time, the vacuum generator provides negative pressure to the suction nozzle 100 through the end of the first slot 101 away from the suction head 30 until the suction head 30 absorbs the material 200. The transfer mechanism drives the suction nozzle 100 and the vacuum generator to drive the material 200 to rise, thereby completing the material 200 removal. In addition, the transfer mechanism can also drive the suction nozzle 100 and the vacuum generator to move the material 200 toward the product. When the material 200 at the lower end of the suction head 30 contacts the product, the transfer mechanism drives the suction nozzle 100 and the material 200 to press the product downward, so that the base 10 presses the elastic part 40 axially downward, and the material 200 is in close contact with the product. At the same time, the vacuum generator stops working, and the transfer mechanism drives the suction nozzle 100 and the vacuum generator to rise, and the material 200 is attached to the product.

[0065] In the above-mentioned assembly equipment, the transfer mechanism drives the vacuum generator and the base 10 to move, so that the suction head 30 can move toward the material 200 and adsorb the material 200 under the action of negative pressure. The suction head 30 and the base 10 in the above-mentioned suction nozzle 100 will not shake relative to each other. In this way, the suction head 30 and the transfer mechanism will not shake relative to each other. Driven by the above-mentioned transfer mechanism, the suction nozzle 100 can accurately act on the material 200, and the structure is stable and the operation accuracy is high.

[0066] In some embodiments, the receiving groove 13 has a top wall and an opening, one end of the elastic member 40 is connected to the top wall of the receiving groove 13 , and the other end of the elastic member 40 passes through the opening and is connected to the suction head 30 .

[0067] In some embodiments, see Figures 1 to 4 The elastic member 40 is a spring. The outer periphery of the sliding portion 21 and the inner ring 12 can fill the hollow part in the middle of the spring, and while guiding the elastic member 40 to elastically deform along the axial direction, the elastic member 40 is not easily dislocated and deformed during the elastic compression process, which can protect the elastic member 40 and increase the service life of the elastic member 40.

[0068] In some embodiments, when the elastic member 40 is elastically compressed, the base 10 and the suction head 30 are relatively close to each other in the axial direction until the base 10 abuts against the suction head 30, the sliding portion 21 is inserted into the inner ring 12, the elastic member 40 is sleeved on the outer periphery of the inner ring 12, and the elastic member 40 is entirely located in the accommodating groove 13, so that the inner ring 12 supports the inner periphery of the elastic member 40, and the outer ring 11 protects the outer periphery of the elastic member 40.

[0069] In some embodiments, see Figures 3 to 5 , a slide groove 211 extending in the axial direction is provided on the sliding part 21. The base 10 is provided with a plug-in hole 14. The plug-in hole 14 is radially penetrated in the outer ring 11 and the inner ring 12. The plug-in hole 14 may penetrate the outer ring 11 and the inner ring 12, or may not completely penetrate the outer ring 11 and the inner ring 12. The suction nozzle 100 also includes a plug-in component 50. The plug-in component 50 is penetrated in the plug-in hole 14 and the slide groove 211, so that the connector 20 and the base 10 are connected through the plug-in component 50. When the sliding part 21 moves axially relative to the inner ring 12, at least part of the sliding part 21 moves axially in the first slot 101, and the slide groove 211 moves relative to the plug-in component 50 in the first slot 101. The plug-in component 50 is fixed relative to the base 10, and the plug-in component 50 can limit the slide groove 211 to move only in the axial direction, and can prevent the connector 20 from rotating relative to the base 10. Among them, the axial direction and the radial direction are two directions perpendicular to each other.

[0070] In some embodiments, see Figure 3 , the connector 50 is a pin. The inner diameter of the plug hole 14 is the same as the outer diameter of the pin. The width of the slide groove 211 is the same as the diameter of the pin. After the pin is inserted into the plug hole 14 and the slide groove 211, the base 10, the pin and the slide groove 211 are stably connected, and the pin and the slide groove 211 can only move relative to each other in the axial direction. A sealant layer is provided between the pin and the plug hole 14. The sealing between the pin and the plug hole 14 can be increased, and the leakage of negative pressure can be reduced. The plug hole 14 is provided at the end of the elastic member 40 away from the suction head 30. The connector 50 can be prevented from interfering with the movement of the elastic member 40.

[0071] In some embodiments, see Figure 3 and Figure 5 The cross section of the inner ring 12 is annular. The inner contour of the cross section is circular. The cross section of the receiving groove 13 is annular. It can better fit the shape of the elastic member 40 to guide the elastic deformation of the elastic member 40 and support the elastic member 40 to increase the service life of the elastic member 40.

[0072] In some embodiments, see Figure 3 , Figure 6 and Figure 7, the connector 20 includes a plug-in portion 22. The plug-in portion 22 is connected to one end of the sliding portion 21 away from the inner ring 12. The suction head 30 includes a matching portion 31. The matching portion 31 has a second slot 311. The plug-in portion 22 is plugged into the second slot 311, so that the suction head 30 and the connector 20 are plugged through the second slot 311 and the plug-in portion 22, and the first channel 201 is connected to the second slot 311. The plug-in portion 22 extends in the axial direction, and the second slot 311 extends in the axial direction. The base 10 and the suction head 30 are relatively close to or relatively far away from each other in the axial direction, and the plug-in portion 22 is plugged into the second slot 311 in the axial direction. The direction in which the base 10 and the suction head 30 are relatively close to or relatively away from each other is parallel to the direction in which the plug-in portion 22 is inserted into the second slot 311. This ensures that during the relative movement between the base 10 and the suction head 30, the plug-in portion 22 will not damage the second slot 311 in directions other than the axial direction, thereby preventing the gap between the second slot 311 and the plug-in portion 22 from increasing and avoiding a reduction in the connection stability between the suction head 30 and the connector 20.

[0073] In some embodiments, in order to make the connection between the suction head 30 and the connector 20 more stable, a sealant layer is provided between the second slot 311 and the plug-in portion 22, which can make the connection between the suction head 30 and the connector 20 more stable and improve the sealing of the connection between the suction head 30 and the connector 20. In detail, a sealant is applied to the periphery of the plug-in portion 22, and then the plug-in portion 22 is inserted into the second slot 311, and a sealant layer is formed after the sealant is air-dried. In addition, after the plug-in portion 22 is inserted into the second slot 311, a sealant can be dripped into the connection between the second slot 311 and the plug-in portion 22, and a sealant layer is formed after the sealant is air-dried.

[0074] In some embodiments, in order to make the connection between the suction head 30 and the connecting member 20 more stable, a connecting hole is provided on the second slot 311 and the matching portion 31, and a screw or a pin is used to connect the suction head 30 and the connecting member 20 through the connecting hole. This can make the connection between the suction head 30 and the connecting member 20 more stable and prevent the connecting member 20 and the suction head 30 from rotating relative to each other.

[0075] In some embodiments, see Figures 1 to 4 The suction head 30 further includes an adsorption portion 32. The adsorption portion 32 is connected to an end of the matching portion 31 away from the base 10. The cross section of the adsorption portion 32 along the radial direction is rectangular. The end of the adsorption portion 32 away from the matching portion 31 is used to contact the material 200, and the rectangular adsorption portion 32 can better adapt to the material 200.

[0076] In some embodiments, see Figure 3 , Figure 6 and Figure 7, the adsorption part 32 is provided with a plurality of adsorption holes 321. The plurality of adsorption holes 321 are arranged on opposite sides of the adsorption part 32. The plurality of adsorption holes 321 can also be arranged on the peripheral side of the adsorption part 32. It can better act on multiple areas of the material 200 to better adsorb the material 200. The plurality of adsorption holes 321 are all connected to the second slot 311, so that the adsorption holes 321 and the second slot 311 form a second channel 301. The adsorption holes 321 penetrate the adsorption part 32 along the axial direction, so that the second channel 301 penetrates the suction head 30 along the axial direction.

[0077] In some embodiments, see Figure 3 and Figure 5 The cross-sections of the first slot 101 and the second slot 311 are both circular. The inner diameter of the second slot 311 is larger than the inner diameter of the first slot 101. Negative pressure acts on the material 200 through the first slot 101, the first channel 201, and the second channel 301. The second slot 311 with a larger inner diameter can connect multiple adsorption holes 321 to adsorb the material 200.

[0078] In some embodiments, see Figure 3 and Figure 4 The connector 20 further includes a stopper 23. The stopper 23 is disposed between the sliding portion 21 and the plug-in portion 22. When the connector 20 is connected to the suction head 30 through the plug-in portion 22, the suction head 30 is connected to the other end of the elastic member 40 through the stopper 23. When the base 10 and the suction head 30 are relatively close to each other in the axial direction until the base 10 abuts against the suction head 30, the inner ring 12 abuts against the stopper 23. The outer diameter of the stopper 23 is greater than the inner diameter of the second slot 311. When the plug-in portion 22 is plugged into the second slot 311, the stopper 23 abuts against the suction head 30 to limit the depth of the plug-in portion 22 inserted into the second slot 311, thereby achieving the effect of positioning the insertion depth of the plug-in portion 22.

[0079] In some embodiments, in order to improve the stability of the connection between the suction head 30 and the base 10, the connecting member 20 and the elastic member 40 can be set as two, and the sliding portion 21 of one connecting member 20 is sleeved with an elastic member 40. The base 10 and the suction head 30 are connected through two connecting members 20, so that the connection between the suction head 30 and the base 10 is more stable, which can increase the service life of the suction nozzle 100.
