The present invention relates to an electronic part pickup device.

A tape-and-reel device for electronic part packaging or an electronic part test handler includes a step of picking up an electronic component element loaded on a tray. A device used for picking up an electronic component in such processes is often used as a pickup device or a pick-up tool.

BACKGROUND ART [0002] When an electronic component such as a semiconductor chip is moved to a tray, is taken out of a tray, or is mounted at another place, the pickup device basically includes an adsorption unit formed at the lower part thereof. This adsorption unit is for picking up electronic components and has a cavity through which a vacuum is applied in the direction of the electronic component through the drilled hole. When the electronic component is sucked by the suction unit, the electronic component is transported by the movement of the pickup device along the rail, for example.

Most of the recent pickup apparatuses employ a linear motor driving method. When a plurality of pickup apparatuses are formed as one set, a linear motor is directly mounted on the pickup apparatus. Each of these pickup devices can perform mutually independent operations.

On the other hand, in the case of the conventional pick-up devices, in order to move to the electronic component mounting position and rotate according to the mounting direction of the electronic component, each pickup tool is provided with a plurality of motors and a plurality of the accompanying devices. The space occupied by the tool was too large to increase the number of pickup tools installed so that the improvement of the work speed (UPH) was restricted.

1 to 7, an electronic part pickup apparatus according to one example includes elevation power unit 10, uppower transmission unit 20, rotational power unit 30, torque transmission unit 50, 60). 1 to 7, in another example, the electronic part pick-up apparatus may further include a connecting unit 70. Fig. In another example, the electronic part pickup device may further include a support frame unit 40. [

Although one electronic component pickup apparatus is described in the present specification and drawings, in one example, a plurality of electronic component pickup apparatuses can form one set. For example, at this time, each electronic component pickup apparatus forming one set can operate integrally or independently.

Hereinafter, each configuration will be described in detail.

Referring to Figs. 1 to 7, the elevation power unit 10 provides power for raising and lowering the electronic part pickup device. For example, the lifting power unit 10 can be provided with a rotation pulley 11 on its side to provide the lifting power of the electronic part pickup device through the timing belt 21, for example.

1, 2, 4, 5, 6 and / or 7, the elevation power unit 10 is mounted on the support frame unit 40, for example, the frame bracket 48 of the support frame unit 40 Can be connected. At this time, the elevation power unit 10 can be supported by the support frame unit 40.

For example, in Figs. 1 to 7, the elevation power unit 10 may include a stepping motor as the elevation power providing device. The stepping motor rotates the rotating pulley 11 on the side of the up / down power unit 10 and provides power necessary for raising and lowering the electronic part pickup device through the up / down force transmitting unit 20, for example, the timing belt 21 can do. Alternatively, a rotary cylinder may be used instead of the step motor as the elevating power providing device to provide the power required for the elevating and lowering. Alternatively, although not shown, a generic cylinder may be used as a lifting power providing device to provide lifting power through a rod connected to the end of the piston. In this case, the rod connected to the piston end may be the booster transmission unit 20.

Next, referring to Figs. 1 to 7, the electronic part pickup apparatus is provided with a booster transmission unit 20. Fig. The upward / downward force transmission unit 20 receives the upward / downward force from the up / down power unit 10 and transmits the upward / downward movement. For example, the boom-tight transmission unit 20 receives the power required for the elevation provided from the elevation power unit 10 such as a step motor (not shown) or a cylinder (not shown) or the like to transmit the elevation movement. At this time, the rotation power unit 30 to be described later can be raised and lowered by the lift-up movement transmitted from the boom-height transmission unit 20. [

For example, referring to Figs. 1, 2, 4, 5 and / or 6, the booster transmission unit 20 may be installed to be supported on the support frame unit 40. At this time, the connecting unit (70) supported by the support frame unit (40) can be raised and lowered in accordance with the upward / downward movement transmitted from the booster transmission unit (20).

For example, referring to Figs. 1-7, in one example, the lift transmission unit 20 may include a timing belt 21 and an idler pulley 23. For example, when the lifting power unit 10 is a device that provides a rotational force such as a step motor or a rotary cylinder, the lifting transmission unit 20 is provided with a timing belt 21 to move up and down through the timing belt 21 . At this time, the timing belt 21 can connect the rotating pulley 11 of the up / down power unit 10 and the idle pulley 23 disposed immediately below the rotating pulley 11. [ At this time, the timing belt 21 can be partially lifted and lowered in the positive and negative rotations in accordance with the positive and negative rotations of the elevation power unit 10. That is, a part of the timing belt 21 between the rotary pulley 11 and the idle pulley 23 is raised or lowered or lifted or lowered according to the positive rotation and the anti-rotation of the lifting power unit 10, can do. For example, when the timing belt 21 is partly lifted and lowered, the connecting unit 70 for connecting between the up-and-down transmission unit 20 and the rotary power unit 30 is lifted and lowered and the rotary power unit 30 And can be lifted and lowered.

The idle pulley 23 may be formed on the support frame unit 40 directly under the rotary pulley 11. [ Reference numeral 23 in Fig. 7 denotes the opposite side of the idle pulley. The idle pulley 23 is rotated by the timing belt 21. The idle pulley 23 is rotated by the positive rotation and the counterclockwise rotation of the lifting power unit 10, (Anti-rotation) so that some sections can be raised and lowered. At this time, the timing belt 21 is partially raised and lowered in accordance with the positive rotation and the negative rotation of the lifting power unit 10, so that the timing belt 21 is supported by the connecting unit 70 and the connecting unit 70 The rotary power unit 30 can be raised and lowered. For example, the connecting unit 70 includes a belt clamp 73 fixedly coupled to the timing belt 21, and can be moved up and down integrally with the timing belt 21. [

1 to 7, a step-up transmission unit 20 including a timing belt 21 and an idle pulley 23 is shown, but in another example not shown, for example, a reciprocating piston of a lifting power unit And a rod (not shown) connected to the load transmission unit (not shown).

Next, with reference to Figs. 1 to 7, the rotational power unit 30 will be described. The rotary power unit (30) is provided with a small-sized motor and moves up and down according to an up-and-down movement in the up-and-down transmission unit. The small motor provided in the rotary power unit 30 is for rotating the suction unit 60 to be described later from side to side and is composed of a rotary force transmitting unit 50, (Not shown). In addition, the small motor can be operated by connecting the cable 80 shown in Figs. 1, 3, 4, 5 and / or 7, specifically, for example, the motor cable 80a and the encoder cable 80b. For example, the motor cable 80a and the encoder cable 80b may be connected through a cap 30a at the upper end of the rotational power unit 30 to transmit driving and control signals to the small motor.

1 to 7, in one example, the rotational power unit 30 is supported by the connecting unit 70 and is moved up and down by the connecting unit 70 And can be lifted and lowered. The connecting unit 70 will be described in detail below.

Next, the rotational force transmitting unit 50 will be described with reference to Figs. The rotational force transmitting unit (50) is connected to the lower portion of the rotational power unit (30) and ascends and descends integrally with the rotational power unit (30). At this time, the rotational force transmitting unit 50 connected to the lower portion of the rotational power unit 30 can transmit the rotational force of the small motor to the adsorbing unit 60.

For example, in one example, the rotational force transmitting unit 50 is supported by the support frame unit 40, and the support frame unit 40 is rotatably supported by the rotational power unit 30 according to the lifting / It is possible to guide and support the lifting and lowering of the rotational force transmitting unit 50, which is integrated with the lifting and lowering of the lifting unit.

Referring to Figs. 1 to 7, in one example, the rotational force transmitting unit 50 may include a coupling portion 51, a spline shaft 53, and a bearing block 55. Fig. The coupling portion 51 is connected to the lower portion of the rotary power unit 30 and transmits the rotational force of the small motor to the spline shaft 53. The spline shaft 53 rotates in accordance with the rotational force transmitted from the coupling portion 51 and the lower end is connected to the adsorption unit 60. The suction unit 60 connected to the lower end of the spline shaft 53 can rotate left and right. In addition, the bearing block 55 supports the rotation of the spline shaft 53. The bearing block 55 is installed in the spline housing 54 supported by the support frame unit 40 and supports the spline shaft 53 on the support frame unit 40 via the spline housing 54 , And the spline shaft 53 can be rotated smoothly.

1 to 7, in another example, the rotational force transmitting unit 50 may further include a fitting block 52 and a spline housing 54. In this case, At this time, the fitting block (52) connects the coupling portion (51) and the spline shaft (53). The spline housing 54 is supported by the support frame unit 40 and covers the spline shaft 53 and the bearing block 55. The spline housing 54 is supported by the support frame unit 40 so that the spline shaft 53 can be eventually supported by the support frame unit 40 by the inner bearing block 55. [ For example, at this time, the support frame unit 40 may be provided with stoppers 47a and 47b to support the upper and lower portions of the spline housing 54.

Next, the adsorption unit 60 will be described with reference to Figs. The adsorption unit 60 is connected to the lower portion of the rotation force transmission unit 50 and moves up and down according to the upward and downward movement of the rotation force transmission unit 50 and rotates left and right according to the rotation force of the rotation force transmission unit 50. For example, the adsorption unit 60 can be operated in accordance with the rotational force of the rotational power unit 30, for example, immediately after the pickup of the object, for example, the electronic component or during the movement along the feed rail (not shown) And can be rotated to the left or right by a predetermined range. For example, in one example, during the transportation of the object to be adsorbed to the electronic part pickup device to the pick-up state, the object can be rotated in a desired direction in a desired direction according to the left or right rotation of the absorption unit 60. Accordingly, when the electronic part pickup apparatus according to one example of the present invention is used, for example, in an electronic part test handler or a tape-and-reel unit for packaging electronic parts, the working efficiency can be improved and the processing time can be shortened.

For example, in one example, the adsorption unit 60 may rotate in the range of approximately 90 degrees to the left and approximately 90 degrees to the right by the rotational force transmitted by the miniature motor. Or in another example, the direction of rotation of the adsorption unit 60 may be different from that in the direction of rotation.

1 to 7, in one example, the suction unit 60 is provided with an air hole 61 at a lower portion thereof. At this time, the air hole 61 forms, for example, a vacuum or low-pressure space between the surface of the electronic component and the surface of the object to be adsorbed. Further, the suction unit (60) may be provided with a vent hole at the side portion thereof. At this time, a vent hole 63 is provided in the vent hole and can be connected to an external air pump or a vacuum pump (not shown) through an air duct (not shown). Accordingly, the vent hole can suck air from the air hole 61 or supply air to the air hole 61. [

1 to 7, another example of the electronic part pickup device will be described. According to one example, the electronic part pickup apparatus may further include a connecting unit 70. [ At this time, the connecting unit 70 can connect and support the rotary power unit 30 and the booster transmission unit 20 so that the rotary power unit 30 is lifted and lowered in accordance with the upward / downward movement of the booster transmission unit 20 have.

For example, the connecting unit 70 is supported by the support frame unit 40, and is supported by the lifting support frame unit 40 of the connecting unit 70 according to the lifting and lowering motion of the lifting / And can be guided by the LM guide 43.

For example, referring to Figures 1-7, in one example, the connecting unit 70 may include a support bracket 71 and a belt clamp 73. The support bracket (71) can support the rotation power unit (30). For example, a housing support portion 71a connected to the bracket main body 71b of the support bracket 71 supports the rotation power unit 30, for example, the rotation power unit housing. The support bracket 71 can be raised and lowered by the support frame unit 40 along the guide of the LM guide 43, for example. At this time, the bracket body 71b of the support bracket 71 is fitted with the partner guide 71c engaged with the LM guide 43 so that the support bracket 71 can be moved up and down according to the guide of the LM guide 43. [

On the other hand, the belt clamp 73 of the connecting unit 70 is supported by the support bracket 71 and is fixedly fastened to the timing belt 21. Thus, the belt clamp 73 can be raised and lowered integrally with the timing belt 21 of the up / down transmission unit 20. [ At this time, since the belt clamp 73 is supported by the support bracket 71, for example, the bracket main body 71b and the rotation power unit 30 is fixed by the support bracket 71, for example, the housing support portion 71a, The rotary power unit 30 can be raised and lowered together with the belt clamp 73 raised and lowered integrally with the rotary shaft 21.

4, 5 and / or 7, a part of the section of the timing belt 21, for example, a section between the rotary pulley 11 and the idle pulley 23, And the belt clamp 73 is fixedly engaged in this section so that the rotational power unit 10 can be raised and lowered integrally with the timing belt 21. [ That is, as the belt clamp 73 is fixedly fastened to the belt section that rises and falls between a specific section of the timing belt 21, that is, between the rotary pulley 11 and the idle pulley 23, The timing belt 21 is moved up and down integrally. At this time, the rotational power unit 30 can move up and down by a distance that the timing belt 21 moves up and down.

5 to 7, in one example, the connecting unit 70 may further include a buffer part 75. [ The cushioning portion 75 connects the belt clamp 73 and the support bracket 71 and can buffer the change of the ascending / descending movement in accordance with the lifting / lowering motion of the lifting / The cushioning portion 75 may be provided between the support plate 71d of the support bracket 71 and the extension plate 73a of the belt clamp 73. [ At this time, in another example, a spring portion 45 connected to the support frame unit 40 may be provided on the extension plate 73a of the belt clamp 73. [

For example, in one example, the buffer 75 may include a buffer spring 75b and a shaft 75a. For example, although not shown in Figs. 5 to 7, an additional shaft is provided inside the buffer spring 75b, so that two shafts 75a can be provided. The cushioning spring 75b connects the belt clamp 73 and the support bracket 71 so as to buffer the change of the support bracket 71 in the ascending and descending movement of the belt clamp 73. Since the belt clamp 73 is fixed to the timing belt 21, the buffer spring 75b buffers the change of the lifting and lowering of the support bracket 71 as the belt clamp 73 moves up and down. The shaft 75a is provided between the support bracket 71 and the belt clamp 73 and can prevent the belt clamp 73 from swinging to the left and right as it ascends and descends. For example, two shafts 75a are provided and it is possible to prevent the belt clamp 73 from rocking right and left when lifting the belt clamp 73. At this time, one shaft can be installed inside the buffer spring 75b. The buffer spring 75b and the shaft 75a may be provided between the support plate 71d of the support bracket 71 and the extension plate 73a of the belt clamp 73. [

Further, in one example, the support bracket 71 may have a connection portion 71d to be connected to the spring portion 45 of the support frame unit 40, which will be described later. The spring portion 45 connected to the connecting portion 71d can prevent the lowering due to the own weight of the rotary power unit 10 fixed to the timing belt 21 in the off operation of the elevation power unit 10 have. It is also possible to buffer the lifting impact without interfering with the lifting and lowering of the rotary power unit 30 by the spring portion 45 connected to the connecting portion 71d during the on operation of the lifting power unit 10. [ 1 and 2, the spring portion 45 of the support frame unit 40 may be formed of a tension spring and may be connected to the connection portion 71d of the support bracket 71.

1 to 7, another example of the electronic part pickup device will be described. According to one example, the electronic component pickup apparatus may further include a support frame unit 40. [ The support frame unit 40 supports the connecting unit 70 and / or the torque transmission unit 50 in accordance with the upward / downward movement of the up / down transmission unit 20, and connects the connecting unit 70 and / 50 can be guided up and down. For example, the idle pulley 23 of the booster transmission unit 20 is mounted on the support frame unit 40 to support the booster transmission unit 20, and the stopper 47 To support the rotational force transmitting unit 50. [

For example, in one example, the support frame unit 40 may include a linear motion (LM) guide 43 and a spring 45. The LM guide 43 guides the lifting and lowering of the connecting unit 70, for example, the lifting and lowering of the supporting bracket 71. That is, the LM guide 43 engages with the partner guide 71c of the support bracket 71 and can guide and support the lifting and lowering of the connecting unit 70. [ The spring unit 45 is connected to the connecting unit 70 and includes a connecting unit 70 fixed to the timing belt 21 by the belt clamp 73 in the off operation of the elevation power unit 10, It is possible to prevent a descent due to the self weight of the rotary power unit 30 or the like connected to the brake pedal 70. For example, the spring portion 45 may be attached to the frame bracket 48 and the connecting unit 70, such as the support bracket 71, see Figs. 1-4, And a tension spring connected between the connecting unit 70a and the connecting shaft 73a so as to prevent the falling of the connecting unit 70 and the rotary power unit 30 due to their own weight during the off operation of the elevation power unit 10. [

For example, the support frame unit 40 may be formed such that the frame body 41 is elongated along the connecting unit 70 and the rotational force transmitting unit 50. An LM guide 43 is provided on the frame body 41 of the support frame unit 40 to guide the lifting and lowering of the connecting unit 70. [ For example, the spring portion 45 may be provided on a protruding projection on the upper side of the frame body 41 and may be connected to the support bracket 71 of the connecting unit 70 or the extension plate 73a of the belt- have. 1, 2, 4, 5, 6 and / or 7, the support frame unit 40 may be provided with a frame bracket 48 to support the elevation power unit 10.

For example, in another example, the support frame unit 40 may have stoppers 47, 47a, 47b. The stopper 47 is provided so as to protrude from the frame body 41 and can support the torque transmission unit 50, for example, the spline housing 54 of the torque transmission unit 50. For example, the stopper 47 may be composed of an upper stopper 47b formed on the upper portion of the spline housing 54 and a lower stopper 47a formed on the lower portion of the spline housing 54. At this time, the lower stopper 47a can restrict the rising range of the adsorption unit 60. [ In addition, the upper stopper 47b can limit the falling range of the torque transmission unit 50, for example, the fitting block 52 of the torque transmission unit 50. As a result, the stopper 47 can restrict the range in which the rotational power unit 30, the rotational force transmitting unit 50, and / or the adsorption unit 60 are lifted or lowered.
