Description

Technical Field

[0001] The utility model relates to the technical field of handling equipment, in particular to a suction nozzle device. Background Art

[0002] During the chip packaging test, the chip needs to be moved, such as moving the chip from the tray to the tape to make a reel, or removing the chip from the tape and putting it into the tray for retesting or re-burning the bottom-layer driver.

[0003] Generally, a nozzle device is used to pick up chips to carry them. The nozzle device has a variable distance mechanism and a lifting mechanism. The variable distance mechanism is used to adjust the distance between each nozzle, and the lifting mechanism can lift the nozzle to a suitable height. In this way, the nozzle device completes the chip transportation through the cooperation of the variable distance mechanism and the lifting mechanism.

[0004] However, the lifting mechanism of the nozzle device of the traditional technology often drives the nozzle to rise and fall by the cooperation of the synchronous belt and the pulley. The cooperation between the synchronous belt and the pulley causes the lifting speed of the nozzle to be slow, which cannot meet the high production rhythm. Utility Model Content

[0005] Based on this, it is necessary to provide a suction nozzle device that can increase the suction nozzle lifting speed to meet a higher production rhythm in order to address the problem that the traditional suction nozzle device setting method causes the suction nozzle to lift and lower speed to be slow and cannot meet a higher production rhythm.

[0042] See also Figure 1 In one embodiment of the present application, a nozzle device 100 is provided for sucking a product, thereby facilitating the handling of the product. In some specific embodiments, the product sucked by the nozzle device 100 may be a chip. It should be understood that in other specific embodiments, the type of product sucked by the nozzle device 100 is not limited, such as other types of electronic components.

[0043] The following is a more detailed description of the present application by taking the nozzle device 100 used to suck a chip as an example. It should be noted that this description is only an example and does not limit the protection scope of the present application.

[0044] The nozzle device 100 includes a mounting seat 10, a pitch-changing mechanism 20, a lifting mechanism 30 and a nozzle mechanism 40. The lifting mechanism 30 and the nozzle mechanism 40 each include at least two. The pitch-changing mechanism 20 is mounted on the mounting seat 10, at least one of the lifting mechanisms 30 is connected to the pitch-changing mechanism 20, and the remaining lifting mechanisms 30 are mounted on the mounting seat 10. The pitch-changing mechanism 20 is used to drive at least one lifting mechanism 30 connected thereto to move relative to the mounting seat 10 along a first direction (i.e., the X direction) to adjust the spacing of each lifting mechanism 30 along the first direction. Each nozzle mechanism 40 is mounted on each lifting mechanism 30 in a one-to-one correspondence, and the lifting mechanism 30 is used to drive the nozzle mechanism 40 to reciprocate along a second direction (i.e., the Y direction). The nozzle mechanism 40 is used to suck chips. The first direction intersects with the second direction. Specifically, the first direction is perpendicular to the second direction.

[0045] It should be noted that at least one of the lifting mechanisms 30 is connected to the pitch-changing mechanism 20, and the remaining lifting mechanisms 30 are installed on the mounting seat 10, which can be understood as: there are at least two lifting mechanisms 30, at least one of the lifting mechanisms 30 is connected to the pitch-changing mechanism 20, and the remaining lifting mechanisms 30 are fixedly installed on the mounting seat 10 and have no direct connection relationship with the pitch-changing mechanism 20. For example, in some embodiments, there are three lifting mechanisms 30, two of which are connected to the pitch-changing mechanism 20, and the remaining one is fixedly installed on the mounting seat 10. Of course, in some other embodiments, when there are three lifting mechanisms 30, it can also be arranged that all three lifting mechanisms 30 are connected to the pitch-changing mechanism 20, and there is no lifting mechanism 30 that has no direct connection relationship with the pitch-changing mechanism 20.

[0046] It should also be noted that the variable pitch mechanism 20 is used to drive at least one lifting mechanism 30 connected thereto to move relative to the mounting seat 10 along the first direction. Adjusting the spacing of each lifting mechanism 30 along the first direction can be understood as: the variable pitch mechanism 20 can change the position of at least one lifting mechanism 30 connected thereto relative to the mounting seat 10 along the first direction, thereby adjusting the spacing between the lifting mechanism 30 and other lifting mechanisms 30, and then adjusting the spacing of each lifting mechanism 30 along the first direction. For example, in some embodiments, there are three lifting mechanisms 30, two of which are connected to the variable pitch mechanism 20, and the remaining lifting mechanism 30 is fixedly mounted on the mounting seat 10. The variable pitch mechanism 20 can change the position of one lifting mechanism 30 connected thereto relative to the mounting seat 10 along the first direction, or change the position of two lifting mechanisms 30 connected thereto relative to the mounting seat along the first direction, thereby adjusting the spacing of each lifting mechanism 30 along the first direction.

[0047] With the above arrangement, when it is necessary to pick up and place the chip, the variable distance mechanism 20 is controlled to adjust the spacing of the lifting mechanism 30 along the first direction, so that each suction nozzle mechanism 40 is at the target position along the first direction, and the lifting mechanism 30 is controlled to drive the suction nozzle mechanism 40 to move along the second direction, so that each suction nozzle mechanism 40 is at the target position along the second direction, so as to facilitate the picking up and placing of the chip.

[0048] In some embodiments, see Figure 1 , each lifting mechanism 30 is directly opposite in the first direction, each suction nozzle mechanism 40 is directly opposite in the first direction, and at the same time, each lifting mechanism 30 drives the suction nozzle mechanism 40 to move in the second direction by the same stroke. In this way, each suction nozzle mechanism 40 can move between the first preset position and the second preset position in the second direction, which helps each suction nozzle mechanism 40 to absorb chips located on the same working surface or place chips on the same working surface.

[0049] In some embodiments, the mounting base 10 includes a mounting plate 11, and the pitch-changing mechanism 20 and the lifting mechanism 30 are both mounted on the mounting plate 11. Specifically, the pitch-changing mechanism 20 is mounted on one side of the mounting plate 11 in the thickness direction (third direction, Z direction) of the mounting plate 11, and the lifting mechanism 30 and the suction nozzle mechanism 40 are both located on the other side of the mounting plate 11. The lifting mechanism 30 is connected to the pitch-changing mechanism 20 through a connecting plate (not shown) that is penetrated through the mounting plate 11. The first direction, the second direction, and the third direction intersect each other. Specifically, the first direction, the second direction, and the third direction are perpendicular to each other.

[0050] It should be understood that in some other embodiments, the structure of the mounting base 10 is not limited, and the relative installation relationship of the variable distance mechanism 20, the lifting mechanism 30 and the suction nozzle mechanism 40 on the mounting base 10 is not limited.

[0051] In some specific implementations, please refer to Figure 1 The nozzle device 100 includes three lifting mechanisms 30, and the lifting mechanism 30 located in the middle along the first direction is fixedly connected to the mounting plate 11. Figure 2 The pitch-changing mechanism 20 includes a pitch-changing drive member 21, a screw rod 22 and a nut 23. The screw rod 22 is connected to the pitch-changing drive member 21. The screw rod 22 has a threaded section with opposite rotation directions. Two nuts 23 are respectively screwed to the two threaded sections. The remaining two lifting mechanisms 30 are respectively connected to the two nuts 23 through a connecting plate. Among them, the pitch-changing drive member 21, the screw rod 22 and the nut 23 are all arranged on the mounting seat 10. Specifically, the pitch-changing drive member 21 is installed on the mounting plate 11. One end of the screw rod 22 is connected to the pitch-changing drive member 21 through a coupling, and the other end is arranged on the mounting plate through a support seat. The two nuts 23 are screwed to the two threaded sections of the screw rod 22 and are screwed thereto. In this way, the pitch-changing drive member 21 drives the screw rod 22 to rotate. The rotation of the screw rod 22 can drive the two nuts 23 to move toward or away from each other, so that the two lifting mechanisms 30 located at the edge are close to or away from each other, thereby adjusting the spacing of the three lifting mechanisms 30 along the first direction. The screw rod 22 and the nut 23 cooperate to realize stepless pitch change and high-precision positioning after the pitch change.

[0052] In some other embodiments, the number of lifting mechanisms 30 included in the suction nozzle device 100 is not limited, and there is no limitation on which lifting mechanism 30 moves relative to the mounting seat 10 along the first direction. In some specific embodiments, the suction nozzle device 100 can also be configured to include two lifting mechanisms 30, one of the two lifting mechanisms 30 is connected to the variable distance mechanism 20, and the other is fixedly connected to the mounting seat 10, and the variable distance mechanism 20 drives the lifting mechanism 30 connected thereto to move along the first direction; or, both lifting mechanisms 30 are connected to the variable distance mechanism 20, and the variable distance mechanism 20 drives the two lifting mechanisms 30 to move closer or farther along the first direction. In some further specific embodiments, the suction nozzle device 100 includes three lifting mechanisms 30, the lifting mechanism 30 located in the middle along the first direction is connected to the variable distance mechanism 20, and the lifting mechanisms 30 located on both sides are fixedly connected to the mounting seat 10, and the variable distance mechanism 20 drives the lifting mechanism 30 connected thereto to move along the first direction, thereby adjusting the distance between it and the lifting mechanisms 30 on both sides along the first direction. In some other specific embodiments, the suction nozzle device 100 includes more than three lifting mechanisms 30, such as four or five, and there is no limitation on which lifting mechanism 30 is connected to the variable distance mechanism 20 and which lifting mechanism 30 is fixedly connected to the mounting base 10, as long as the setting method can achieve adjustment of the spacing between the lifting mechanisms 30 along the first direction.

[0053] There is no limitation on the structural arrangement of the pitch-changing mechanism 20. For example, the pitch-changing mechanism 20 may include only the pitch-changing driving member 21. The number of the pitch-changing driving members 21 is equal to the number of the lifting mechanisms 30 connected thereto. Each pitch-changing driving member 21 is used to drive the lifting mechanism 30 to move along the first direction relative to the mounting plate 11. Specifically, the pitch-changing driving member 21 is a motor.

[0054] See also Figure 3-Figure 5 The nozzle device 100 further includes a first guide mechanism 50, which includes a first slider 51 and a first guide rail 52 extending along a first direction. The first slider 51 is provided on one of the lifting mechanism 30 and the mounting plate 11, and the first guide rail 52 extends along the first direction and is provided on the other of the lifting mechanism 30 and the mounting plate 11. The first slider 51 and the first guide rail 52 are slidably matched along the first direction to enable the lifting mechanism 30 to move along the first direction. That is, when the lifting mechanism 30 moves along the first direction, the first slider 51 and the first guide rail 52 cooperate to enable the lifting mechanism 30 to move along the first direction, thereby preventing the lifting mechanism 30 from deviating.

[0055] In some specific embodiments, the first guide rail 52 is disposed on the mounting plate 11, and the first guide rails 52 corresponding to all the lifting mechanisms 30 connected to the pitch-changing mechanism 20 are connected and integrated into one body. It is conceivable that in some other embodiments, each first guide rail 52 may also be disposed separately.

[0056] In some embodiments, see Figure 3 , Figure 4 and Figure 6 At least one lifting mechanism 30 includes a lifting drive member 31 and a connecting rod assembly 32. The connecting rod assembly 32 is hinged to the lifting drive member 31 and the nozzle mechanism 40, and the lifting drive member 31 drives the nozzle mechanism 40 to reciprocate along the second direction through the connecting rod assembly 32. Specifically, when the lifting drive member 31 drives the connecting rod assembly 32, the connecting rod assembly 32 rotates relative to the lifting drive member 31 and the nozzle mechanism 40, thereby driving the nozzle mechanism 40 to move along the second direction.

[0057] With the above arrangement, when it is necessary to adjust the position of the nozzle mechanism 40 along the second direction, the lifting drive 31 drives the connecting rod assembly 32 to move, and the connecting rod assembly 32 drives the nozzle mechanism 40 to move along the second direction. Compared with the prior art method of driving the nozzle to rise and fall by the cooperation of the synchronous belt and the pulley (the method of driving the nozzle to rise and fall by the cooperation of the synchronous belt and the pulley, the motor needs to rotate a large angle to drive the nozzle to rise and fall within the preset stroke, and the response speed is slow), the connecting rod assembly 32 can respond quickly under the drive of the lifting drive 31 (for example, when the lifting drive 31 drives the connecting rod assembly 32 by rotating, the lifting drive 31 can drive the nozzle mechanism 40 to rise and fall within the preset stroke by rotating a small angle), which can increase the lifting speed of the nozzle mechanism 40 along the second direction and meet the needs of a higher production cycle.

[0058] Optionally, each lifting mechanism 30 includes a lifting drive member 31 and a connecting rod assembly 32. It is conceivable that in some other embodiments, some lifting mechanisms 30 may include a lifting drive member 31 and a connecting rod assembly 32, which is not limited here.

[0059] In some specific embodiments, the connecting rod assembly 32 includes only one connecting rod 321, one end of which is hinged to the lifting drive member 31, and the other end is hinged to the suction nozzle mechanism 40. In other specific embodiments, the connecting rod assembly 32 includes at least two connecting rods 321 hinged to each other, in which case the suspended end of the connecting rod 321 at one end of the connecting rod assembly 32 is hinged to the lifting drive member 31, and the suspended end of the connecting rod 321 at the other end of the connecting rod assembly 32 is hinged to the suction nozzle mechanism 40.

[0060] The nozzle device 100 further includes a rocker 70, which is connected to the lifting drive member 31, and a connecting rod 321 is hinged to the rocker 70 and the nozzle mechanism 40. The lifting drive member 31 can drive the rocker 70 to swing, and the rocker 70 drives the connecting rod 321 to move. During the movement of the connecting rod 321, the connecting rod 321, the nozzle mechanism 40 and the rocker 70 rotate relative to each other, thereby driving the nozzle mechanism 40 to move along the second direction. Specifically, the lifting drive member 31 is a motor.

[0061] In some embodiments, see Figure 1 The nozzle device 100 further includes a second guide mechanism 60, and the number of the second guide mechanism 60 is equal to that of the nozzle mechanism 40 and they are arranged one by one. Figure 1 , and see Figure 7 The second guide mechanism 60 includes a second slider 61 and a second guide rail 62 that are slidably connected. The second slider 61 is installed on one of the lifting mechanism 30 and the nozzle mechanism 40, and the second guide rail 62 is installed on the other of the lifting mechanism 30 and the nozzle mechanism 40. The second slider 61 and the second guide rail 62 are slidably matched along the second direction, so that the nozzle mechanism 40 moves along the second direction.

[0062] In some specific implementations, please refer to Figure 7 The lifting mechanism 30 connected to the pitch changing mechanism 20 further includes a lifting plate 33, which is slidably connected to the mounting plate 11 along the first direction through the first guide mechanism 50, and the second slider 61 or the second guide rail 62 in the second guide mechanism 60 is arranged on the lifting plate 33. The lifting drive member 31 and the connecting rod assembly 32 are both installed on the lifting plate 33. The lifting mechanism 30 directly fixedly installed on the mounting plate 11 can omit the lifting plate 33, and in this case, the second slider 61 or the second guide rail 62 in the second guide mechanism 60 corresponding thereto can be directly arranged on the mounting plate 11.

[0063] With the above arrangement, when the nozzle mechanism 40 moves along the second direction relative to the lifting mechanism 30, the second guide mechanism 60 corresponding to the nozzle mechanism 40 can guide the nozzle mechanism 40 to move along the second direction to prevent the nozzle mechanism 40 from deviating when moving along the second direction.

[0064] See also Figure 8 The nozzle mechanism 40 includes a fixed plate 41, and the second slider 61 or the second guide rail 62 in the second guide mechanism 60 is arranged on the fixed plate 41. In addition, the nozzle mechanism 40 is hinged to the connecting rod assembly 32 through the fixed plate 41.

[0065] Each suction nozzle mechanism 40 also includes a rotary drive member 42, a synchronous belt 43, two pulleys 44, a rotating shaft 45 and a suction nozzle 46. The rotary drive member 42 is mounted on the fixed plate 41, and the rotating shaft 45 is supported on the fixed plate 41. The two pulleys 44 are respectively connected to the rotary drive member 42 and the rotating shaft 45, and the synchronous belt 43 is sleeved on the two pulleys 44. Among them, the rotating shaft 45 extends along the second direction, the suction nozzle 46 is mounted on the rotating shaft 45, the rotating shaft 45 is provided with an air flow channel, and the suction nozzle 46 is connected to the air flow channel. Specifically, the rotary drive member 42 is a motor.

[0066] With the above arrangement, the rotating driving member 42 can drive the pulley 44 connected thereto to rotate, and drive another pulley 44 to rotate through the synchronous belt 43, the rotating shaft 45 rotates, and the suction nozzle 46 rotates synchronously with the pulley 44, and the suction nozzle 46 can drive the chip to rotate to any angle for positioning. At the same time, the suction nozzle 46 can be connected to the air source through the air flow channel on the rotating shaft 45, such as a trachea air inlet joint is provided at the other end of the rotating shaft 45 away from the suction nozzle 46, and is connected to the air source through the trachea air inlet joint.

[0067] For further information, see Figure 8 and Fig. 9 , a sealing ring 47 is provided inside the suction nozzle 46 and / or outside the rotating shaft 45, the suction nozzle 46 is connected to the rotating shaft 45 by plugging, and the sealing ring 47 is sealed between the rotating shaft 45 and the suction nozzle 46. In this way, the suction nozzle 46 and the rotating shaft 45 are connected by a quick plug method, which is convenient for the replacement of the suction nozzle 46, and the structural adaptability is good, which can meet the production needs of more and more varieties of chips. At the same time, a sealing ring 47 is provided between the suction nozzle 46 and the rotating shaft 45, that is, Fig. 9 The suction nozzle 46 is installed in Figure 8 Outside the rotating shaft 45, a sealing ring 47 is arranged between the suction nozzle 46 and the rotating shaft 45, which can tighten and fix the suction nozzle 46 and the rotating shaft 45 to meet the installation accuracy requirements.

[0068] Each suction nozzle mechanism 40 also includes a first support seat 48 and a second support seat 49 arranged at intervals along the second direction, and the first support seat 48 and the second support seat 49 are both arranged on the fixed plate 41. The two ends of the rotating shaft 45 are respectively supported and rotated through the first support seat 48 and the second support seat 49, and the suction nozzle 46 is installed on one end of the rotating shaft 45 extending from the second support seat 49. Under the support of the first support seat 48 and the second support seat 49, the rotating shaft 45 is prevented from shaking too much during the rotation process to ensure stability; at the same time, by adjusting the position of the first support seat 48 and the second support seat 49 on the fixed plate 41, the verticality of the rotating shaft 45 is adjusted to avoid deviation in the first direction and the third direction when rotating at different angles, which makes it easier to ensure the rotation accuracy. Specifically, the first support seat 48 and the second support seat 49 are both provided with bearings, and the two ends of the rotating shaft 45 are respectively arranged in the first support seat 48 and the second support seat 49 through bearings, and the rotating shaft 45 can rotate relative to the first support seat 48 and the second support seat 49 through the bearings at both ends.

[0069] In some embodiments, see Fig. 9 and Fig.10The suction nozzle 46 includes a sleeve 461, a buffer 462 and a suction portion 463. One end of the suction portion 463 is installed in the sleeve 461, and the other end extends out of the sleeve 461. A first stop portion is provided in the sleeve 461, and a second stop portion is provided in the suction portion 463. The buffer 462 is provided in the sleeve 461 and is located between the first stop portion and the second stop portion in the axial direction of the sleeve 461. Among them, the suction nozzle 46 is sleeved on the outside of the rotating shaft 45 through the sleeve 461. In this way, when the suction portion 463 of the suction nozzle 46 contacts the chip, the suction portion 463 is subjected to the pressure applied by the chip, and the buffer 462 can be elastically deformed, so that the suction portion 463 and the chip are in elastic contact. That is, the suction portion 463 and the chip are in soft contact, which plays a role in protecting the chip and preventing the chip from being crushed compared to the hard contact method.

[0070] Furthermore, the suction nozzle 46 further includes an anti-rotation pin 464, and a long hole 4611 is provided on the sleeve 461, and the long hole 4611 extends along the axial direction of the sleeve 461. The anti-rotation pin 464 is connected to the suction part 463 and is movably arranged in the long hole 4611 along the axial direction of the sleeve 461. On the one hand, the anti-rotation pin 464 cooperates with the long hole 4611 to prevent the suction part 463 from rotating relative to the sleeve 461 when sucking the chip, thereby ensuring the suction accuracy; on the other hand, the anti-rotation pin cooperates with the long hole 4611 to guide the suction part 463.

[0071] The suction principle of the nozzle device 100 provided in the embodiment of the present application is as follows:

[0072] The variable pitch drive member 21 drives the screw rod 22 to rotate, and the screw rod 22 rotates to drive the two nuts 23 connected thereto to move in opposite directions or toward each other, so as to adjust the spacing between the three lifting mechanisms 30 in the first direction, thereby adjusting the spacing between the three suction nozzles 46 along the first direction. The lifting drive member 31 drives the rocker 70 to rock, and the rocker 70 drives the connecting rod 321 to move. The connecting rod 321 rotates relative to the rocker 70 and the fixed plate 41. Under the guidance and limiting action of the second guide mechanism 60, the connecting rod assembly 32 drives the suction nozzle mechanism 40 to rise and fall in the second direction to adjust the position of the suction nozzle 46 along the second direction. The rotating drive member 42 drives the rotating shaft 45 to rotate, thereby driving the suction nozzle 46 to rotate to a suitable angle. When the spacing of each suction nozzle 46 along the first direction, the position of each suction nozzle 46 along the second direction, and the rotation angle are adjusted, the chip can be taken and placed.

[0073] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
