Description

Technical Field

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

[0002] With the continuous development of automation technology, in the semiconductor field, when transferring electronic products, a nozzle is usually used for picking and placing. When multiple electronic products need to be picked and placed at the same time, multiple nozzle devices are usually arranged to pick and place multiple products at the same time to improve production efficiency.

[0003] In the field of modern manufacturing, especially in operations involving frequent changes of nozzle types, the traditional nozzle change method usually relies on manual adjustment. Since it is completely dependent on manual operation, it is difficult to ensure the accuracy of the adjustment. Operators often need to rely on experience and visual inspection to adjust the position, which leads to large errors in the adjustment results and cannot meet the high-precision production requirements. Summary of the invention

[0004] The object of the present invention is to provide a nozzle adjustment device to solve the technical problem of high error in manually adjusting the spacing of the nozzles in the prior art.

[0010] The driving assembly can be selectively connected to any of the suction nozzle assemblies. The driving assembly includes a first driving mechanism and a second driving mechanism. The first driving mechanism can drive the adsorption component to rise or lower; the second driving mechanism can drive the suction nozzle assembly to move in a horizontal direction.

[0012] Preferably, a compression spring is arranged between the sliding sleeve and the adsorption part. When the sliding sleeve moves in a direction approaching the adsorption part, the compression spring contracts and deforms, thereby driving the adsorption part to rise; when the sliding sleeve moves in a direction away from the adsorption part, the compression spring recovers and stretches, thereby driving the adsorption part to be lowered.

[0013] Preferably, a movable stopper is provided on the sliding sleeve, and the movable stopper can extend or retract along the second straight line direction. The first limiting member is a limit stopper, and the limit stopper is opposite to the movable stopper. When the movable stopper is extended, the bottom of the movable stopper abuts against the top of the limit stopper, thereby limiting the movement of the sliding sleeve along the support member.

[0014] Preferably, the first unlocking member can face the movable stopper and move along the second straight line direction to push the movable stopper to retract, thereby unlocking the limit stopper.

[0015] Preferably, a return spring is provided on the movable stopper, and when the first unlocking member pushes the movable stopper to retract, the return spring is compressed and deformed, and when the first unlocking member moves away from the movable stopper, the return spring recovers the deformation and extends, thereby driving the movable stopper to extend.

[0016] Preferably, a limit rod extending along the first straight line direction is provided on the main body, and the second limit member is a rotating stopper, which is rotatably connected to the support member and can rotate along the height direction of the support member so that the rotating stopper contacts or moves away from the limit rod, thereby locking or unlocking the support member.

[0018] Preferably, a pushing surface is formed on the rotating block, and the second unlocking member can face the pushing surface and move along the second straight line direction to push the rotating block to rotate, so that the bottom surface of the rotating block is away from the top surface of the limiting rod, thereby unlocking the rotating block.

[0019] Preferably, a guide rod extending along a first straight line direction is provided on the main body, and the support member is sleeved on the guide rod and slidably connected to the guide rod.

[0020] Beneficial effects of the present invention:

[0021] The nozzle adjustment device proposed in the present invention can simultaneously adsorb multiple objects to be adsorbed by setting a plurality of nozzle assemblies arranged at intervals along the first straight line direction, thereby improving work efficiency. The setting of the first limiter and the second limiter can effectively limit the movement of the adsorbent in the vertical and horizontal directions, ensuring the stability of the position of the adsorbent under normal working conditions, thereby improving the accuracy and reliability of adsorption. The first unlocking member and the second unlocking member of the unlocking assembly can respectively release the first limiter and the second limiter, so that the adsorbent can be released from the restriction when adjustment is required and the position can be adjusted flexibly. The first driving mechanism can realize the lifting or lowering of the adsorbent, and the second driving mechanism can drive the nozzle assembly to move in the horizontal direction, thereby adjusting the spacing between the nozzle assemblies.

[0037] See also Figures 1 to 6The nozzle adjustment device provided by the embodiment of the present invention includes a main body 1, a nozzle assembly 2, an unlocking assembly 3 and a driving assembly 4. Among them, a plurality of nozzle assemblies 2 are connected to the main body 1 and arranged at intervals along the first straight line direction. The nozzle assembly 2 includes a support 21 and an adsorbent 22, a first limiter and a second limiter arranged on the support 21. The first limiter can limit the adsorbent 22 to move in the vertical direction; the second limiter can limit the adsorbent 22 to move in the horizontal direction, and the adsorbent 22 can adsorb the object to be adsorbed; the unlocking assembly 3 can be selectively connected to any nozzle assembly 2, the unlocking assembly 3 includes a first unlocking member and a second unlocking member, the first unlocking member can release the first limiter; the second unlocking member can release the second limiter; the driving assembly 4 can be selectively connected to any nozzle assembly 2, the driving assembly 4 includes a first driving mechanism and a second driving mechanism, the first driving mechanism can drive the adsorbent 22 to rise or lower; the second driving mechanism can drive the nozzle assembly 2 to move in the horizontal direction.

[0038] The nozzle adjustment device proposed in the present invention can simultaneously absorb multiple objects to be sucked by setting a plurality of nozzle assemblies 2 arranged at intervals along the first straight line direction, thereby improving work efficiency. The setting of the first limiter and the second limiter can effectively limit the movement of the adsorption member 22 in the vertical and horizontal directions, ensuring the stability of the position of the adsorption member 22 under normal working conditions, thereby improving the accuracy and reliability of adsorption. The first unlocking member and the second unlocking member of the unlocking assembly 3 can respectively release the first limiter and the second limiter, so that the adsorption member 22 can be released when adjustment is required and the position can be adjusted flexibly. The first driving mechanism can realize the lifting or lowering of the adsorption member 22, and the second driving mechanism can drive the nozzle assembly 2 to move in the horizontal direction, thereby adjusting the spacing between the nozzle assemblies 2. In summary, compared with the prior art that completely relies on manual adjustment of the nozzle spacing and has a high error, the present invention can realize automatic and high-precision nozzle position adjustment through the coordinated cooperation of the nozzle assembly 2, the unlocking assembly 3 and the driving assembly 4, improve the efficiency and quality of production, meet the needs of modern high-precision production, and reduce the errors and uncertainties caused by manual operation.

[0039] The specific structure of the nozzle adjustment device is described below.

[0040] In this embodiment, the suction member 22 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 drawn out from the tip of the suction nozzle, thereby generating negative pressure at the tip of the suction nozzle to achieve the adsorption 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.

[0041] In order to make the adsorption member 22 move in the vertical direction to realize the process of raising or lowering the adsorption member 22, the first driving mechanism includes a power member and a sleeve 41. The sleeve 41 is sleeved on the support member 21 and is slidably connected to the support member 21. The adsorption member 22 is connected to the sleeve 41. The power member can drive the sleeve 41 to slide along the support member 21, thereby driving the adsorption member 22 to rise or lower in the vertical direction. The support member 21 extends in the vertical direction, so that the support member 21 can provide a stable and reliable guide for the vertical movement of the sleeve 41, ensuring that the sleeve 41 always moves along the predetermined vertical path during the process of raising or lowering, thereby improving the accuracy and stability of the position adjustment of the adsorption member 22.

[0042] Among them, the power parts can be selected from existing motors, hydraulic pumps and other equipment, which will not be described in detail here.

[0043] Specifically, a compression spring 42 is provided between the sliding sleeve 41 and the adsorbent 22. When the sliding sleeve 41 moves in a direction close to the adsorbent 22, the compression spring 42 contracts and deforms, thereby driving the adsorbent 22 to rise; when the sliding sleeve 41 moves in a direction away from the adsorbent 22, the compression spring 42 recovers and stretches, thereby driving the adsorbent 22 to descend. The setting of the compression spring 42 provides a buffering effect for the raising and lowering of the adsorbent 22. When the sliding sleeve 41 moves in a direction close to the adsorbent 22, the compression spring 42 contracts and deforms, driving the adsorbent 22 to rise. The contracted compression spring 42 can slow down the speed of the rise, avoiding the impact of too fast rise on the device or the object to be adsorbed. Similarly, when the sliding sleeve 41 moves in a direction away from the adsorbent 22, the compression spring 42 recovers and stretches, driving the adsorption to descend, and its elongation process can also play a buffering effect, making the lowering process smoother. In addition, the elastic deformation of the compression spring 42 can compensate for the unstable driving force of the driving mechanism to a certain extent, ensuring that the raising and lowering actions of the adsorption member 22 are more uniform and continuous.

[0044] More specifically, a movable stopper 43 is provided on the sliding sleeve 41, and the movable stopper 43 can be extended or retracted along the second straight line direction. The first limiting member is the limiting stopper 23, and the limiting stopper 23 is opposite to the movable stopper 43. When the movable stopper 43 is extended, the bottom of the movable stopper 43 abuts against the top of the limiting stopper 23, thereby limiting the movement of the sliding sleeve 41 along the support member 21.

[0045] The first unlocking member is used to unlock the movable block 43, thereby releasing the limit on the sliding sleeve 41. Specifically, the first unlocking member can face the movable block 43 and move along the second straight line direction to push the movable block 43 to retract, thereby unlocking the limit block 23. In this embodiment, the first unlocking member is the first fork 31, and the head end of the first fork 31 has a first fork plate and a second fork plate arranged at an interval, and a connecting plate is arranged between the first fork plate and the second fork plate, and the first fork plate, the second fork plate and the connecting plate are arranged in a U-shape. After the first fork 31 moves a certain distance toward the movable stopper 43 along the second straight line direction, at least a part of the movable stopper 43 is suitable for entering between the first fork plate and the second fork plate, and the end of the movable stopper 43 abuts against the connecting plate. When the first fork 31 continues and moves along the second straight line direction, the connecting plate can push the movable stopper 43 to move in the direction away from the limit stopper 23 until the bottom of the movable stopper 43 is away from the top of the limit stopper 23, thereby releasing the limit on the sliding sleeve 41, so that the sliding sleeve 41 can slide along the support member 21, thereby compressing or releasing the compression spring 42, and realizing the raising or lowering process of the adsorption member 22.

[0046] When the nozzle assembly 2 needs to be locked, the first shift fork 31 is moved in a direction away from the movable stopper 43 until the movable stopper 43 exits between the first fork plate and the second fork plate, so that the movable stopper 43 is extended to achieve the limiting effect on the limit stopper 23. Specifically, a return spring is provided on the movable stopper 43. When the first unlocking member pushes the movable stopper 43 to retract, the return spring is compressed and deformed. When the first unlocking member is away from the movable stopper 43, the return spring recovers the deformation and stretches, thereby driving the movable stopper 43 to extend. The return spring ensures the automatic reset of the movable stopper 43 after the unlocking operation. When the first unlocking member pushes the movable stopper 43 to retract, the return spring is compressed and deformed; when the first unlocking member is away from the movable stopper 43, the return spring recovers the deformation and stretches, thereby driving the movable stopper 43 to extend, thereby achieving automatic limiting, reducing the need for manual intervention, and improving the convenience and efficiency of operation.

[0047] In other embodiments, the movable stopper 43 may be actively driven to extend through a telescopic motor, a hydraulic cylinder or other equipment, which will not be described in detail here.

[0048] Regarding the driving process of the first unlocking member, in this embodiment, the unlocking assembly 3 includes a driving motor, a guide rail, a slider and a belt. The driving motor serves as a source of power, and the first unlocking member is fixedly mounted on the slider. When the driving motor is started, its output shaft drives the belt to move. Since the first unlocking member is fixed on the slider that can slide along the guide rail, the movement of the belt can drive the slider to move accurately in a straight line along the guide rail, thereby pushing the first unlocking member to move in a predetermined direction.

[0049] For example, when the movable stopper 43 needs to be unlocked, the drive motor rotates forward, and the belt drives the guide rail slider and the first fork 31 to move toward the movable stopper 43 until the first fork 31 contacts the movable stopper 43 and pushes it to retract, completing the unlocking action. After the unlocking is completed, the drive motor rotates in the reverse direction, and the belt drives the slider and the first fork 31 away from the movable stopper 43, and the movable stopper 43 loses its force, causing the return spring to recover its deformation and extend, thereby driving the movable stopper 43 to extend.

[0050] In addition, positioning grooves are provided on both sides of the movable stopper 43, and positioning protrusions are provided through the positioning grooves and fixedly connected to the sliding sleeve 41. The positioning grooves are extended 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 oblong extending positioning grooves and the two ends being able to abut against the positioning protrusions limits the moving range of the movable stopper 43, prevents it from being excessively extended or retracted, and ensures that the movable stopper 43 works normally within the effective stroke.

[0051] In order to make the nozzle assembly 2 move in the horizontal direction to achieve the spacing adjustment process of the nozzle assembly 2, the second driving mechanism is connected to the nozzle assembly 2 and drives the nozzle assembly 2 connected thereto to move in the horizontal direction, and the second limiter is used to lock or unlock the horizontal movement process of the nozzle assembly 2. Specifically, a limiter rod extending along the first straight line direction is provided on the main body 1, and the second limiter is a rotating block 24, which is rotatably connected to the support member 21, and the rotating block 24 can rotate along the height direction of the support member 21, so that the rotating block 24 contacts or moves away from the limiter rod, thereby locking or unlocking the support member 21.

[0052] The second driving mechanism may be selected from existing equipment such as a screw nut pair, a cylinder or a hydraulic pump, which will not be elaborated here. It only needs to ensure that it can drive the suction nozzle assembly 2 to move in the horizontal direction.

[0053] Specifically, the top surface of the limit rod is provided with a plurality of limit grooves, and the bottom surface of the rotating block 24 is provided with ridges corresponding to the limit grooves. When the rotating block 24 contacts the limit rod, the ridges can be engaged with the limit grooves, thereby limiting the horizontal movement of the support member 21. The engagement between the ridges and the limit grooves enhances the limiting effect on the horizontal movement of the support member 21. The engagement structure makes the locking more firm and reliable, and can effectively prevent the support member 21 from moving or shaking slightly in the horizontal direction.

[0054] In other embodiments, an electromagnet may be provided on the limiting rod. When the rotating stopper 24 contacts the limiting rod, the electromagnet is energized to attract the rotating stopper 24 , thereby achieving a limiting effect on the rotating stopper 24 .

[0055] The second unlocking member is used to unlock the rotating block 24, thereby releasing the limit on the support member 21. Specifically, a push surface 240 is formed on the rotating block 24, and the second unlocking member can face the push surface 240 and move along the second straight line direction to push the rotating block 24 to rotate, so that the bottom surface of the rotating block 24 is away from the top surface of the limit rod, thereby unlocking the rotating block 24. In this embodiment, the second unlocking member is a second shift fork 32, and the head end of the second shift fork 32 has a third fork plate and a fourth fork plate arranged at intervals, and an adapter plate is arranged between the third fork plate and the fourth fork plate, and the third fork plate, the fourth fork plate and the adapter plate are arranged in a U shape. After the second shift fork 32 moves a certain distance toward the movable block 43 along the second straight line direction, at least a part of the rotating block 24 is suitable for entering between the third fork plate and the fourth fork plate, and the push surface 240 of the movable block 43 abuts against the adapter plate, and the push surface 240 has a high end 241 adjacent to the second shift fork 32 and a low end 242 away from the second shift fork 32. When the head end of the second fork 32 moves along the pushing surface 240 from the high end portion 241 to the low end portion 242, the second fork 32 pushes the bottom surface of the rotating block 24 to rotate in a direction away from the limiting rod, so that the bottom surface of the rotating block 24 is separated from the top surface of the limiting rod, that is, the convex ridge is separated from the limiting groove, thereby releasing the locking effect on the support member 21.

[0056] It should be pointed out that, taking the contact plane when the bottom surface of the rotating stopper 24 contacts the top surface of the limiting rod as the reference plane, in the locked state, the distance between the high end 241 of the pushing surface 240 and the reference plane is greater than the distance between the low end 242 and the reference plane.

[0057] When the nozzle assembly 2 needs to be locked, the second fork 32 is moved in a direction away from the rotating block 24 until the rotating block 24 exits between the third fork plate and the fourth fork plate, so that the rotating block 24 is reset and the convex ridge is engaged with the limiting groove to achieve the limiting effect on the rotating block 24. Specifically, a telescopic spring is arranged between the top surface of the rotating block 24 and the support member 21. When the second fork 32 pushes the bottom surface of the rotating block 24 to rotate in a direction away from the limiting rod, so that the bottom surface of the rotating block 24 is separated from the top surface of the limiting rod, the top surface of the rotating block 24 moves upward, thereby compressing the telescopic spring, and when the second fork 32 is withdrawn, the rotating block 24 loses the driving force, and the telescopic spring recovers the deformation and stretches, thereby driving the bottom surface of the rotating block 24 to rotate in a direction close to the limiting rod, so that the bottom surface of the rotating block 24 contacts the top surface of the limiting rod, that is, the convex ridge is engaged with the limiting groove, thereby achieving the locking effect on the support member 21.

[0058] Regarding the driving process of the second unlocking member, it is the same as the first unlocking component 3. In this embodiment, a set of guide rails, sliders and belts are respectively provided for the first unlocking member and the second unlocking member. The two groups share the same driving motor. The driving motor can respectively drive the first unlocking member and the second unlocking member to move along the second straight line direction, which will not be repeated here.

[0059] During the horizontal movement of the nozzle assembly 2, in order to improve the stability of the nozzle assembly 2, a guide rod extending along the first straight line direction is provided on the main body 1, and the support member 21 is sleeved on the guide rod and slidably connected with the guide rod. The guide rod provides precise guidance for the horizontal movement of the support member 21. It ensures that the horizontal movement of the support member 21 follows a predetermined straight line trajectory, avoids the support member 21 from being offset or skewed during the movement, and thus improves the accuracy and precision of the position adjustment of the nozzle assembly 2.

[0060] In addition, the unlocking component 3 also includes a sensor 33, which can monitor the positions of the first unlocking member and the second unlocking member and generate a prompt message to prevent the other devices from being activated when the first unlocking member and the second unlocking member are not fully released or fully retracted, causing interference between the devices and causing damage.

[0061] It is understandable that the sensor 33 is an existing electrical device, and its working principle and specific structure are not described in detail here.

[0062] 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.
