Description

Technical Field

[0002] At present, the existing die bonding machines usually adopt the traditional XYZ three-axis motion structure in conjunction with the material picking mechanism to realize the movement of the chip, that is, the X-axis drives the YZ-axis to move, the Y-axis drives the Z-axis to move, and finally the Z-axis drives the material picking mechanism to move, so as to realize the movement of the material picking mechanism in space. Although this traditional XYZ three-axis motion structure has a simple structure, when it is applied to the die bonding machine, it will take up a lot of space after the XYZ three-axis superimposed material picking mechanism, especially for the space in the height direction of the die bonding machine, which will lead to insufficient installation space for structures such as vision modules and transfer platforms. In addition, when the die bonding machine is working, the Y-axis with the highest movement frequency and the fastest speed will generate huge Y-axis inertia during movement due to the weight of the Z-axis and the material picking mechanism, thereby reducing the positioning accuracy, response speed and service life, and further reducing the overall working accuracy of the die bonding machine.

[0035] like Figure 1-Figure 4 As shown, a mobile material-retrieving platform according to an embodiment of the present invention has a first direction X, a second direction Y and a third direction Z intersecting in pairs, and includes: a mounting seat 1, a driving mechanism 2 and a material-retrieving mechanism 3; the mounting seat 1 can slide along the first direction X; the driving mechanism 2 includes a base 21, a sliding portion 22 and a driving plate 23, the base 21 and the driving plate 23 are arranged at intervals on one side of the mounting seat 1 in the first direction X along the second direction Y, the base 21 can slide on the mounting seat 1 along the second direction Y, the driving plate 23 can slide on the mounting seat 1 along the third direction Z, and the base 21 A receiving groove 211 is provided on the side facing the driving plate 23, a connecting groove 212 is provided on the side of the base 21 away from the mounting seat 1, the connecting groove 212 extends along the third direction Z and is connected to the receiving groove 211, the sliding portion 22 is located inside the receiving groove 211 and is slidably connected to the connecting groove 212, and the driving plate 23 has an extension portion 231 on the side facing the receiving groove 211, the extension portion 231 extends along the second direction Y and is slidably connected to the sliding portion 22; the material picking mechanism 3 is located on the side of the base 21 away from the mounting seat 1 and is connected to the sliding portion 22 through the connecting groove 212.

[0036] Based on the above scheme, the present application sets a base 21, a sliding part 22 and a driving plate 23, and the base 21 and the driving plate 23 are set separately, so that when the base 21 slides along the second direction Y, the extension part 231 of the driving plate 23 can also drive the sliding part 22 to move in the third direction Z, so that the base 21 and the driving plate 23 are set on a mounting seat 1 to complete the movement of the material picking mechanism 3 in the space, reducing the space occupied by the stacking of various mechanisms, especially the space occupied by the crystal bonding machine in the third direction Z, leaving sufficient installation space for other mechanisms. In addition, after the base 21 and the driving plate 23 are set separately, the weight borne by the base 21 can also be reduced, thereby reducing the moving inertia of the base 21 in the second direction Y, improving the positioning accuracy, response speed and service life of the base 21, and thereby improving the overall working accuracy of the crystal bonding machine. The driving plate 23 and the base 21 can also move simultaneously during use, further improving the working efficiency of the crystal bonding machine.

[0037] like Figure 5As shown, in order to ensure the movement accuracy of the base 21 and the driving plate 23, the mounting base 1 includes a base 11, a first track 12 and a second track 13. The first track 12 and the second track 13 are arranged at intervals along the second direction Y on one side of the base 11 in the first direction X. The first track 12 extends along the second direction Y, and the second track 13 extends along the third direction Z. The base 21 is slidably connected to the first track 12, and the driving plate 23 is slidably connected to the second track 13. The movement routes of the base 21 and the driving plate 23 are ensured by setting the first track 12 and the second track 13.

[0038] like Figure 5 As shown, in order to ensure that the base 21 can move more stably, the first track 12 includes a first base 121 and a first guide rod 122. The first base 121 has a first limiting groove 1211 on the side away from the mounting base 1, and the first guide rod 122 is arranged in the first limiting groove 1211 and extends along the second direction Y. The base 21 has a first sleeve portion 213 on the side away from the material picking mechanism 3. The first sleeve portion 213 is sleeved on the first guide rod 122 and can slide in the first limiting groove 1211 along the first guide rod 122.

[0039] like Figure 5 As shown, in order to ensure that the sliding part 22 can move stably along the third direction Z, the second track 13 is connected to the mounting seat 1 at one end in the third direction Z, and the other end protrudes from the mounting seat 1. The driving plate 23 also includes a driving part 232, and the driving part 232 is slidably connected to the second track 13. The extension part 231 is arranged on the side of the driving part 232 facing the base 21. By extending the second track 13 and setting the driving part 232, the driving plate 23 can drive the sliding part 22 to move more stably and will not occupy more space in the third direction Z.

[0040] like Figure 5 As shown, in order to ensure that the driving plate 23 can move more stably, the second track 13 includes a second base 131 and a second guide rod 132, the second base 131 has a second limiting groove 1311 on the side away from the mounting seat 1, the second guide rod 132 is arranged in the second limiting groove 1311 and extends along the third direction Z, the driving plate 23 has a second sleeve portion 233 on the side away from the feeding mechanism 3, the second sleeve portion 233 is sleeved on the second guide rod 132, and can slide in the second limiting groove 1311 along the second guide rod 132.

The first pulley 221 and the second pulley 222 are spaced apart along the third direction Z on the side of the material taking mechanism 3 facing the connecting groove 212, and a sliding space is formed between the first pulley 221 and the second pulley 222, and the extension portion 231 is slidably connected to the sliding space.

[0042] like Figure 1 and Figure 5 As shown, in order to ensure the movement accuracy of the mounting seat 1 , a third track 4 extending along the first direction X is further included, and the mounting seat 1 is slidably connected to the third track 4 .

[0043] like Figure 4 As shown, in order to ensure the moving accuracy of the material picking mechanism 3 and avoid the misalignment of the material picking mechanism 3 due to the sliding of the extension part 231 on the sliding part 22, a plurality of fourth rails 214 are further provided on the side of the base 21 away from the mounting base 1, and the fourth rails 214 extend along the third direction Z. The plurality of fourth rails 214 are arranged at intervals on both sides of the connecting groove 212 along the second direction Y. The material picking mechanism 3 is slidably connected to the plurality of fourth rails 214. By setting a plurality of fourth rails 214, it is ensured that the material picking mechanism 3 can move along the third direction Z without deviation due to the sliding of the driving plate 23 relative to the sliding part 22.

[0044] like Figure 6 As shown, the material taking mechanism 3 further includes a plurality of third sleeve parts 31 , and the plurality of third sleeve parts 31 are sleeved on the plurality of fourth rails 214 one by one.

[0045] like Figure 6 and Figure 7 As shown, in order to reduce the occupation of the internal space of the crystal bonding machine in the third direction Z, the material picking mechanism 3 includes a support plate 32, a rotating motor 33, a transmission belt 34 and a suction nozzle 35. The support plate 32 is connected to the sliding part 22, and the rotating motor 33 and the suction nozzle 35 are arranged on the support plate 32 at intervals along the first direction X, and the suction nozzle 35 is rotatably connected to the support plate 32. The output end of the rotating motor 33 is transmission-connected to the suction nozzle 35 through the transmission belt 34, and the top surface of the suction nozzle 35 has an exhaust port 351, and the exhaust port 351 is used to extract gas. By setting the support plate 32, the rotating motor 33 and the suction nozzle 35 can be arranged at intervals along the first direction X, thereby reducing the occupation of the space in the third direction Z, and after the exhaust port 351 is set on the top surface of the suction nozzle 35, it can also provide space for gas path connection for the mechanism of the crystal bonding machine used to control adsorption.

[0046] like Figure 6-Figure 13As shown, in order to facilitate the control of the pressure applied by the suction nozzle 35 to the chip, the material picking mechanism 3 also includes a force-applying component 36, which includes a force-control spring 361, a support plate 362 and a force-bearing plate 363. The support plate 362 is arranged on the top surface of the support plate 32, and the force-bearing plate 363 is arranged on the side of the support plate 362 facing the suction nozzle 35; the suction nozzle 35 includes a sleeve 352, a shaft 353 and a cap 354, the sleeve 352 is rotatably connected to the support plate 32, and the output end of the rotating motor 33 is driven by a transmission The belt 34 is in transmission connection with the sleeve 352. The sleeve 352 has a mounting hole penetrating along the third direction Z. The shaft 353 is inserted into the mounting hole and both ends protrude from the sleeve 352. The mounting hole has a slide groove 3521 extending along the third direction Z. The outer peripheral side of the shaft 353 has a slide bar 3531 adapted to the slide groove 3521. The slide bar 3531 is slidably connected to the slide groove 3521. The cap 354 is sleeved on the top of the shaft 353, and the shaft 353 is rotatably connected to the cap 354.

[0047] One end of the force control spring 361 is connected to the bottom surface of the force plate 363, and the other end is connected to the cap body 354. By dividing the suction nozzle 35 into the sleeve body 352, the shaft body 353 and the cap body 354, the shaft body 353 of the suction nozzle 35 can rotate with the sleeve body 352 and slide along the third direction Z, thereby cooperating with the force control spring 361 to control the magnitude of the force applied to the chip.

[0048] like Figure 8 and Fig. 9 As shown, in order to facilitate the adjustment of the force control range of the material picking mechanism 3, the force-applying assembly 36 also includes a fixing member 364 and a force-bearing member 365. The fixing member 364 is detachably connected to the force-bearing plate 363. The force-bearing member 365 includes a first force-bearing portion 3651 and a second force-bearing portion 3652. The first force-bearing portion 3651 is arranged on the side of the cap body 354 facing the suction nozzle 35. One end of the second force-bearing portion 3652 is connected to the bottom end of the first force-bearing portion 3651, and the other end extends toward the support plate 362 and is arranged corresponding to the fixing member 364.

By arranging the fixing member 364 and the force-bearing member 365, it is possible to ensure that the force control spring 361 applies a stable force while also being able to conveniently replace the force control spring 361, thereby realizing the adjustment of the force control range of the material picking mechanism 3.

[0049] like Figure 6 and Fig.10As shown, in order to facilitate the control of the force transmitted to the suction nozzle 35 by the force control spring 361 so that it can be transmitted to the chip along the third direction Z, the material picking mechanism 3 also includes a holder 37, and the holder 37 is arranged on the top surface of the support plate 32. The top surface of the holder 37 has a sliding groove 371, and the sliding groove 371 runs through the side of the holder 37 facing the suction nozzle 35. The side of the cap body 354 is provided with a protrusion 3541, and the protrusion 3541 is slidably connected to the sliding groove 371. Through the setting of the protrusion 3541 and the sliding groove 371, it is ensured that in the process of the force control spring 361 applying force, the shaft body 353 and the cap body 354 can move along the third direction Z, thereby ensuring that the force applied by the suction nozzle 35 to the chip can move along the third direction Z, and because the holder 37 is provided, the shaft body 353 and the cap body 354 can be prevented from falling off from the suction nozzle 35 after the force control spring 361 is disassembled.

[0050] like Fig.10 As shown, in order to facilitate the removal of the force control spring 361, the force-bearing member 365 and the protrusion 3541 are symmetrically arranged along the axial direction of the cap body 354, and as the protrusion 3541 slides into the sliding groove 371, the second force-bearing portion 3652 can abut against the top surface of the tray. When the force control spring 361 is removed, the suction nozzle 35 can be supported by the force-bearing member 365 and the bracket 37, thereby avoiding the position of the suction nozzle 35 from being offset.

[0051] like Figure 11-13 As shown, the suction nozzle 35 further includes a suction portion 355 , which is sleeved on the bottom end of the shaft 353 and is used to suction the chip.

[0052] like Figure 1 As shown, in order to facilitate the control of the pressure applied by the suction nozzle 35 to the chip, a displacement sensor 5 is also included. The displacement sensor 5 is arranged corresponding to the shaft 353 and is used to detect the distance moved by the shaft 353 relative to the sleeve 352.

[0053] like Figure 6 As shown, the displacement sensor 5 includes a sensing part 51 and a displacement plate 52. The displacement plate 52 is arranged on the side of the support plate 32, and the sensing part 51 is arranged on the side of the cap body 354 and is arranged corresponding to the displacement plate 52. The sensing part 51 is used to detect the moving distance of the displacement plate 52 relative to the suction nozzle 35, that is, the compression amount of the force control spring 361. The pressure applied by the force control spring 361 is calculated by calculating the compression amount of the force control spring 361, and due to the location of the displacement sensor 5, the disassembly of the force control spring 361 will not be affected.

[0054] An embodiment of the present invention further provides a crystal bonding machine, comprising the mobile material taking platform as described above.

[0055] In summary, the embodiment of the present invention provides a mobile material-taking platform and a crystal bonding machine, which are provided with a base 21, a sliding part 22 and a driving plate 23, and the base 21 and the driving plate 23 are separately provided, so that when the base 21 slides along the second direction Y, the extension part 231 of the driving plate 23 can also drive the sliding part 22 to move in the third direction Z, so that the base 21 and the driving plate 23 are provided on a mounting seat 1 to complete the movement of the material-taking mechanism 3 in the space, thereby reducing the space occupied by the stacking of various mechanisms, especially the space occupied by the crystal bonding machine in the third direction Z, leaving sufficient installation space for other mechanisms. In addition, after the base 21 and the driving plate 23 are separately provided, the weight borne by the base 21 can also be reduced, thereby reducing the moving inertia of the base 21 in the second direction Y, improving the positioning accuracy, response speed and service life of the base 21, and thereby improving the overall working accuracy of the crystal bonding machine. The driving plate 23 and the base 21 can also move simultaneously during use, further improving the working efficiency of the crystal bonding machine.
