Description

Technical Field

[0001] The present invention relates to the technical field of suction nozzle equipment, and in particular to a suction nozzle device. Background Art

[0002] In the field of industrial production, nozzle devices are often used for operations such as product grabbing, handling and assembly. When multiple electronic products need to be picked up and placed at the same time, multiple nozzles are usually arranged to pick up and place multiple products at the same time to improve production efficiency.

[0003] The prior art (202410929940.2) discloses a chip picking and placing device. After the chip is sucked by the suction part, when the chip needs to be put down, the chip can be ejected by moving the ejector toward the chip, so that the chip can be placed on the tray more quickly and stably. However, the suction nozzle spacing of the chip picking and placing device in the prior art is fixed, which makes it only suitable for a type of product with specific specifications. Since the types and sizes of products are not fixed in actual production, when the product type changes, the existing suction nozzle device cannot flexibly adjust the spacing and is difficult to adapt to new production needs. In order to meet the processing requirements of products of different specifications, it is often necessary to replace the entire set of suction nozzle groups, which is not only complicated to operate and affects production efficiency, but also increases production costs. Summary of the invention

[0004] The object of the present invention is to provide a suction nozzle device to solve the technical problem in the prior art that the spacing between multiple suction nozzles in the suction nozzle device cannot be adjusted, resulting in poor adaptability of the suction nozzle device.

The horizontal moving mechanism can drive the supporting body to move in a horizontal direction, and the vertical moving mechanism can drive the supporting body to move in a vertical direction.

[0010] Preferably, the horizontal moving mechanism includes a first motor, a synchronous pulley and a transmission belt, the synchronous pulley is connected to the first motor, the transmission belt is sleeved on the synchronous pulley, the transmission belt extends along a first straight line direction, and the supporting body is connected to the transmission belt.

[0013] Preferably, the sliding sleeve and the adsorption portion are connected by a compression spring. When the sliding sleeve moves in a direction approaching the adsorption portion, the compression spring contracts and deforms, thereby driving the adsorption portion to retract; when the sliding sleeve moves in a direction away from the adsorption portion, the compression spring recovers and stretches, thereby driving the adsorption portion to be lowered.

[0014] Preferably, a movable stopper is provided on the sliding sleeve, and the movable stopper can be extended or retracted along the second straight line direction. A limit stopper is provided on the main body opposite to the movable stopper.

In the retracted state, it can protect the adsorption part and effectively prevent the idle adsorption part from interfering with the adsorption process, thereby improving the adaptability and flexibility of the nozzle unit. The elastic characteristics of the compression spring make the retracting and lowering process of the adsorption part have a certain buffering effect. When retracting, it can reduce the impact and protect the adsorption part and related components from being damaged by excessive force; when lowering, it can smoothly push out the adsorption part to avoid rapid impact and cause unstable adsorption.

[0039] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0040] The embodiment of the present invention provides a suction nozzle device, which can adjust the distance between different suction nozzles and has high adaptability.

[0041] See also Figures 1 to 10 The suction nozzle device provided by the embodiment of the present invention includes a support body 1, a suction nozzle unit 2 and a moving component 3. Among them, a plurality of suction nozzle units 2 are arranged on the support body 1 and arranged along a first straight line direction, the suction nozzle unit 2 is movably connected to the support body 1, the suction nozzle unit 2 can move along the first straight line direction, the suction nozzle unit 2 includes a suction portion 21 and a locking portion, the suction portion 21 can suction the object to be suctioned, and the locking portion can limit the suction nozzle unit 2 from moving relative to the support body 1; the suction nozzle unit 2 also includes a body 23 and a sliding sleeve 24, the sliding sleeve 24 is sleeved on the body 23 and is slidably connected to the body 23, the suction portion 21 is connected to the sliding sleeve 24, the sliding sleeve 24 slides along the body 23, thereby driving the suction portion 21 to be retracted or Lowering; the sliding sleeve 24 and the adsorption part 21 are connected by a compression spring 27. When the sliding sleeve 24 moves in a direction close to the adsorption part 21, the compression spring 27 contracts and deforms, thereby driving the adsorption part 21 to retract; when the sliding sleeve 24 moves in a direction away from the adsorption part 21, the compression spring 27 recovers and stretches, thereby driving the adsorption part 21 to be lowered; the moving component 3 is connected to the supporting body 1, and the moving component 3 includes a horizontal moving mechanism 31 and a vertical moving mechanism 32. The horizontal moving mechanism 31 can drive the supporting body 1 to move in the horizontal direction, and the vertical moving mechanism 32 can drive the supporting body 1 to move in the vertical direction.

[0042] It is defined here that the first straight line direction and the second straight line direction are both horizontal directions, and the two are perpendicular to each other. For the convenience of description in conjunction with the drawings, the directions below are described based on the directions shown in the drawings, but are not limited thereto.

[0043] The suction nozzle device proposed by the present invention is provided on the support body 1 through a plurality of suction nozzle units 2 and arranged along the first straight line direction, and the suction nozzle unit 2 is movably connected with the support body 1 and can move along the first straight line direction, and the spacing between the suction nozzle units 2 can be flexibly adjusted according to the size and shape of different products, without replacing the entire suction nozzle device, thereby reducing the production cost. The suction portion 21 of the suction nozzle unit 2 can effectively adsorb the object to be adsorbed, and the locking portion can limit the movement of the suction nozzle unit 2 relative to the support body 1, ensuring that the position of the suction nozzle unit 2 is stable after the spacing is adjusted, thereby ensuring the accuracy and reliability of the adsorption operation. The horizontal moving mechanism 31 in the moving assembly 3 can drive the support body 1 to move in the horizontal direction, and the vertical moving mechanism 32 can drive the support body 1 to move in the vertical direction, so that the suction nozzle unit 2 can move freely in the three-dimensional space, adapt to different working scenes and position requirements, and improve the versatility and applicability of the suction nozzle device. In addition, in the suction nozzle device of the present application, the locking portion can limit the movement of the suction nozzle unit 2 relative to the support body 1, ensuring that the position of the suction nozzle unit 2 is stable after the spacing is adjusted, thereby ensuring the accuracy and reliability of the adsorption operation. The body 23, the sliding sleeve 24, the compression spring 27 and the adsorption part 21 in the suction nozzle unit 2 form an organic whole structure. The sliding of the sliding sleeve 24 and the body 23 drives the compression spring 27 to extend and contract, so that the retracted and lowered positions of the adsorption part 21 can be accurately controlled, so that the suction nozzle unit 2 can switch accurately in different working states. In the retracted state, it can protect the adsorption part 21 and effectively prevent the idle adsorption part 21 from interfering with the adsorption process, thereby improving the adaptability and flexibility of the suction nozzle unit 2. The elastic characteristics of the compression spring 27 make the retracted and lowered processes of the adsorption part 21 have a certain buffering effect. When retracting, it can reduce the impact and protect the adsorption part 21 and related components from being damaged by excessive force; when lowering, the adsorption part 21 can be pushed out smoothly to avoid rapid impact and unstable adsorption.

[0044] The specific structure of the suction nozzle device is described below.

[0045] In this embodiment, the suction part 21 is a suction nozzle, and a channel connected to an external vacuum source is provided inside the suction nozzle. When the vacuum source is activated, air is extracted from the tip of the suction nozzle, thereby generating negative pressure at the tip of the suction nozzle to achieve the suction of the object to be sucked. In order to better adapt to objects to be sucked of different sizes and shapes, the diameter and length of the suction nozzle have multiple optional specifications, which are not limited here. The suction nozzle is an existing device in the field, and its working principle and specific structure are not described in detail here.

[0046] During use, the position of the suction nozzle unit 2 needs to be adjusted in time by the moving component 3 according to objects to be sucked of different shapes, sizes and positions, so as to achieve the best suction effect.

[0047] In order to facilitate fixing the horizontal moving mechanism 31 and the vertical moving mechanism 32 , the moving assembly 3 includes a longitudinal support 33 and a transverse support 34 . The transverse support 34 extends along the first straight line direction, and the longitudinal support 33 is arranged on both sides of the bottom of the transverse support 34 .

[0048] The horizontal moving mechanism 31 is used to realize the movement process of the suction nozzle unit 2 in the horizontal direction. Specifically, the horizontal moving mechanism 31 includes a first motor 311, a synchronous pulley 312 and a transmission belt 313. The synchronous pulley 312 is connected to the first motor 311, and the transmission belt 313 is sleeved on the synchronous pulley 312. The transmission belt 313 extends along the first straight line direction, and the support body 1 is connected to the transmission belt 313. The motor drive is combined with the belt transmission method, and the transmission is smooth, which can ensure the speed uniformity and position accuracy of the support body 1 during horizontal movement, reduce the jitter and deviation during the movement process, and help to improve the accuracy and reliability of the suction nozzle device in the horizontal direction. At the same time, the belt drive has a certain buffering effect, which can reduce the damage to the equipment caused by instantaneous impact force to a certain extent.

[0049] See also Figure 4 A reducer 314 and a transmission rod 315 are also provided between the motor shaft of the first motor 311 and the pulley 316. The motor shaft of the first motor 311 is connected to the reducer 314. The output end of the reducer 314 is coaxially connected to one end of the transmission rod 315, and the other end of the transmission rod 315 is coaxially connected to the synchronous pulley 312. The reducer 314 can effectively reduce the output speed of the first motor 311, increase the output torque, and enable the nozzle unit 2 to obtain a smoother and more powerful drive when moving horizontally. The transmission rod 315 optimizes the path of power transmission. Through the synergistic effect of the reducer 314 and the transmission rod 315, the power output by the first motor 311 can be more accurately adjusted and controlled, thereby improving the accuracy and repeatability of the horizontal movement of the nozzle unit 2, and better meeting the requirements for nozzle position accuracy under different working conditions.

[0050] More specifically, the horizontal moving mechanism 31 also includes a pulley 316, which can ensure that the transmission belt 313 stably maintains its proper shape during operation, effectively preventing the transmission belt 313 from twisting, deforming or dislocating due to various factors, so that power transmission is always accurate and stable.

[0051] See also Figure 6In addition, fasteners 35 are provided on both sides of the transverse support 34, and the fasteners 35 can fix the conveyor belt 313. In this embodiment, the fasteners 35 are press plates. One end of each fastener 35 is connected to the transverse support 34 through an adjustable screw, and the other end extends to the edge of the conveyor belt 313. When the conveyor belt 313 needs to be fixed, the screws are tightened to press the press plates on both sides of the conveyor belt 313, thereby firmly fixing the conveyor belt 313 to prevent it from being offset or deformed during operation.

[0052] It is understandable that, in other embodiments, the horizontal moving mechanism 31 may also use a screw nut pair, a hydraulic cylinder and other equipment to achieve horizontal movement of the nozzle unit 2, which will not be elaborated here.

[0053] The vertical moving mechanism 32 is used to realize the movement process of the suction nozzle unit 2 in the vertical direction. Specifically, the vertical moving mechanism 32 includes a second motor 321 and a screw rod 322. The screw rod 322 extends in the vertical direction. The screw rod 322 is coaxially connected to the motor shaft of the second motor 321, and the support body 1 is threadedly connected to the screw rod 322. The screw rod 322 is driven by the second motor 321, which can provide accurate and stable power for the movement of the support body 1 in the vertical direction. The transmission of the screw rod 322 has high precision and self-locking characteristics, which can ensure that the support body 1 accurately reaches the specified position when moving vertically, and remains stable when stopping, avoiding position deviation or slipping, thereby improving the accuracy and reliability of the suction nozzle device in the vertical direction.

[0054] It is understandable that, in other embodiments, the vertical moving mechanism 32 may also be connected to the supporting body 1 by the telescopic end of the telescopic motor, so as to realize the vertical movement of the nozzle unit 2, which will not be elaborated here.

[0055] In actual use, for certain objects to be adsorbed, sometimes only part of the adsorption part 21 needs to be used, and there is no need to use the entire adsorption part 21. At this time, in order to prevent the idle adsorption part 21 from causing obstruction and interference to the operation process, part of the adsorption part 21 needs to be folded up, and when this part of the adsorption part 21 is needed, this part of the adsorption part 21 is lowered.

[0056] Regarding the driving process of the sliding sleeve 24, in this embodiment, the sliding sleeve 24 is connected to the supporting body 1, and the supporting body 1 is driven to move in the vertical direction through the vertical moving mechanism 32, thereby synchronously driving the sliding sleeve 24 to move in the vertical direction. In other embodiments, a driving motor or other equipment may also be separately provided for the sliding sleeve 24 to drive the vertical movement process of the sliding sleeve 24, which is not limited here.

[0057] More specifically, in order to ensure the stability of the adsorption part 21 after it is folded or lowered and prevent the sliding sleeve 24 from slipping, a movable stopper 25 is provided on the sliding sleeve 24, and the movable stopper 25 can be extended or retracted along the second straight line direction. A limit stopper 26 is provided on the body 23 opposite to the movable stopper 25. When the movable stopper 25 is extended, the bottom of the movable stopper 25 abuts against the top of the limit stopper 26, thereby limiting the movement of the sliding sleeve 24 along the body 23. The movable stopper 25 can accurately limit the movement of the sliding sleeve 24. When the position of the sliding sleeve 24 needs to be fixed to keep the adsorption part 21 in the folded or lowered state, the movable stopper 25 is extended to abut against the limit stopper 26, so as to achieve the limiting effect.

[0058] When the adsorption part 21 needs to be folded up, the movable stopper 25 is first retracted to release the limiting process of the sliding sleeve 24, and then the support body 1 is driven to move downward in the vertical direction through the vertical moving mechanism 32, thereby synchronously driving the sliding sleeve 24 to move downward in the vertical direction, thereby compressing the compression spring 27, and the compression spring 27 shrinks and deforms, driving the adsorption part 21 to be folded up, and then the movable stopper 25 is extended to achieve the limiting process of the sliding sleeve 24, thereby achieving the stable folding process of the adsorption part 21. When the adsorption part 21 needs to be lowered, the movable stopper 25 is retracted to release the limiting process of the sliding sleeve 24, and the compression spring 27 loses pressure, recovers its deformation and extends, thereby driving the adsorption part 21 to be lowered.

[0059] It is understandable that the extension and retraction process of the movable stopper 25 can be manually operated by an operator, or the movable stopper 25 can be pushed and pulled by a device such as a telescopic rod, which is not limited here.

[0060] It is worth noting that a return spring is provided on the movable stopper 25. When the movable stopper 25 is pushed to retract, the return spring is compressed and deformed. When the thrust on the movable stopper 25 is removed, the return spring recovers its deformation and extends, thereby driving the movable stopper 25 to extend. The return spring ensures the automatic resetting of the movable stopper 25, reduces the need for manual intervention, and improves the convenience and efficiency of operation.

[0061] In addition, positioning grooves are provided on both sides of the movable stopper 25, and the positioning protrusions are inserted through the positioning grooves and fixedly connected to the sliding sleeve 24. The positioning grooves are elongated in an oblong shape, and the positioning grooves are slidably connected to the positioning protrusions, and the two ends of the positioning grooves can abut against the positioning protrusions. The design of the elongated positioning grooves and the two ends of the positioning grooves being able to abut against the positioning protrusions limits the moving range of the movable stopper 25, prevents it from being excessively extended or retracted, and ensures that the movable stopper 25 works normally within the effective stroke.

[0062] The locking part is used to limit the movement of the nozzle unit 2 relative to the support body 1. The support body 1 is provided with a limit rod 11 extending along the first straight line direction, and the locking part is a rotating block 22, which can rotate in the vertical direction so that the rotating block 22 contacts or moves away from the limit rod 11, thereby locking or unlocking the nozzle unit 2.

[0063] See also Fig.10 Specifically, the top surface of the limit rod 11 is provided with a plurality of limit grooves, and the bottom surface of the rotating block 22 is provided with ridges corresponding to the limit grooves. When the rotating block 22 contacts the limit rod 11, the ridges can be engaged with the limit grooves, thereby limiting the movement of the nozzle unit 2 along the first straight line direction. The engagement between the ridges and the limit grooves enhances the limiting effect on the horizontal movement of the nozzle unit 2. The engagement structure makes the locking more firm and reliable, and can effectively prevent the nozzle unit 2 from moving or shaking slightly in the horizontal direction.

[0064] In other embodiments, an electromagnet may be provided on the limiting rod 11 , and when the rotating stopper 22 contacts the limiting rod 11 , the electromagnet is energized to attract the rotating stopper 22 , thereby achieving a limiting effect on the rotating stopper 22 .

[0065] In addition, a telescopic spring is provided on the top surface of the rotating stopper 22. When the rotating stopper 22 is pushed to rotate in a direction away from the limiting rod 11, so that the bottom surface of the rotating stopper 22 is separated from the top surface of the limiting rod 11, the top surface of the rotating stopper 22 moves upward, thereby compressing the telescopic spring; when the thrust on the rotating stopper 22 is removed, the telescopic spring loses pressure, and the telescopic spring recovers its deformation and stretches, thereby driving the bottom surface of the rotating stopper 22 to rotate in a direction close to the limiting rod 11, so that the bottom surface of the rotating stopper 22 contacts the top surface of the limiting rod 11, that is, the convex ridge is engaged with the limiting groove, thereby achieving the locking effect of the suction nozzle unit 2.

[0066] When the spacing between the suction nozzle units 2 needs to be adjusted, first drive the rotating stop block 22 on the suction nozzle unit 2 that needs to be adjusted to rotate in the direction away from the limiting rod 11, so that the convex edge is away from the limiting groove, thereby releasing the limiting effect on the suction nozzle unit 2 in the horizontal direction, and then fix the suction nozzle unit 2 by a fixing device, and drive the support body 1 to move horizontally along the first straight line direction by the horizontal moving mechanism 31, thereby synchronously driving the suction nozzle unit 2 set on the support body 1 to move horizontally along the first straight line direction. Since the suction nozzle unit 2 is fixed and cannot move in the horizontal direction, relative movement occurs between the suction nozzle unit 2 and the other suction nozzle units 2, and then the distance between the suction nozzle unit 2 and the adjacent suction nozzle units 2 on both sides changes. When the distance is adjusted to a suitable position, the thrust on the rotating stopper 22 is removed, the telescopic spring loses pressure, and the telescopic spring recovers its deformation and stretches, thereby driving the bottom surface of the rotating stopper 22 to rotate in the direction close to the limiting rod 11, so that the bottom surface of the rotating stopper 22 contacts the top surface of the limiting rod 11, and the convex ridge is engaged with the limiting groove, thereby realizing the horizontal limitation of the suction nozzle unit 2, thereby completing the adjustment process of the distance between the suction nozzle units 2.

[0067] It is understandable that the rotation process of the rotating block 22 can be manually operated by an operator, or can be driven to rotate by a device such as a telescopic rod, which is not limited here. In addition, the above-mentioned fixing device can be selected from existing devices in the field, such as a fixing clamp, a mechanical arm, etc., which will not be described in detail here.

[0068] During the horizontal movement of the nozzle unit 2, in order to improve the stability of the nozzle unit 2, a guide rod 12 extending along the first straight line direction is provided on the support body 1, and the nozzle unit 2 is sleeved on the guide rod 12 and slidably connected with the guide rod 12. The guide rod 12 provides precise guidance for the horizontal movement of the nozzle unit 2. It ensures that the nozzle unit 2 moves in the horizontal direction along a predetermined straight line trajectory, avoids the nozzle unit 2 from being offset or skewed during the movement, and thus improves the accuracy and precision of the position adjustment of the nozzle unit 2.

[0069] Among them, one, two, etc. guide rods 12 can be provided according to actual needs, and there is no limitation on the number thereof.

[0070] In order to ensure the cleanliness of the internal pipeline of the nozzle unit 2, a filter 4 is provided for each nozzle unit 2. Specifically, the filter 4 is arranged in a cylindrical shape. The inside of the filter 4 is filled with multiple layers of fine filter mesh, and the filter 4 is installed at the air inlet of the nozzle unit 2 by threaded connection. When the gas carries impurities into the internal pipeline of the nozzle unit 2, it first passes through the filter 4. Impurities such as dust and tiny particles in the gas are intercepted and adsorbed by the filter mesh, thereby ensuring that the gas entering the internal pipeline of the nozzle unit 2 is relatively clean, reducing the possibility of pipeline blockage and pollution, and helping to maintain the normal operation and service life of the nozzle unit 2.

[0071] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
