[0032] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0033] Examples, such as Figures 2 to 5 As shown, the present embodiment provides a bonding machine with a precise feeding mechanism, comprising: a workbench 4, a transfer tray 41, a material picking mechanism 1 and a bonding mechanism, etc. The workbench 4 is the mounting base of the bonding machine shown in the present embodiment, and the transfer tray 41, the material picking mechanism 1 and the bonding mechanism are all directly or indirectly mounted on the workbench 4, wherein the transfer tray 41 is placed in the center, and the material picking mechanism 1 and the bonding mechanism are mounted around the transfer tray 41. The transfer tray 41 is rotatably connected to the workbench 4, and a plurality of placement seats 42 are circumferentially provided on the transfer tray 41, and the placement seats 42 are suitable for placing workpieces. The bonding machine is used to bond two chips together through processes such as pressurization and heating. In the above process, the two chips need to be stacked together, and in the present embodiment, the material picking mechanism 1 is used to take and place the chip located on the upper side of the two stacked chips, and place the chip on the placement seat 42 where the lower chip has been placed.

[0034] In order to achieve the effect of transporting the chip from the loading position to the placement seat 42, in this embodiment, as a preference, the material picking mechanism 1 also includes a support seat 17, a translation plate 16, a lifting plate 11 and a material picking chuck 2. The support seat 17 is installed on the workbench 4, the translation plate 16 is slidably set on the support seat 17, the lifting plate 11 is slidably set on the translation plate 16, and the material picking chuck 2 is installed on the lifting plate 11. The translation plate 16 can slide back and forth in the horizontal direction on the support seat 17, and the lifting plate 11 can be lifted up and down in the vertical direction on the translation plate 16. The translation plate 16 and the lifting plate 11 form a composite motion to drive the material picking chuck 2 to move to the loading position, clamp the workpiece, and then move it to the top of the placement seat 42 for unloading. In this way, the automatic feeding of the entire bonding machine can be achieved.

[0035] In order to achieve the effect of horizontal sliding of the translation plate 16 along the support base 17, in this embodiment, as a preference, a translation rail 171 is provided on the support base 17, and the translation plate 16 is slidably provided on the translation rail 171. At the same time, as an option, a power motor is installed on the support base 17, and the movable end of the power motor can be coaxially connected to a screw rod, and the screw rod is threadedly connected to the translation plate 16. Through the above arrangement, when the power motor is started, the screw rod drives the translation plate 16 to slide horizontally along the translation rail 171.

[0036] In order to achieve the effect of vertically lifting the lifting plate 11 along the translation plate 16, in this embodiment, as a preference, a vertical slide rail 161 is provided on the translation plate 16, and the lifting plate 11 is slidably provided on the vertical slide rail 161. At the same time, a lifting motor 162 is also installed on the translation plate 16, and a linkage block 111 is installed on one side of the lifting plate 11, and the lifting motor 162 is transmission-connected to the linkage block 111. Optionally, a driving wheel is provided at the movable end of the lifting motor 162, and a driven wheel is also rotatably provided on the upper portion of the lifting plate 11. The driven wheel is located below the roller, and the driven wheel and the driving wheel are connected by a belt. The linkage block 111 is therefore installed on the belt away from the lifting plate 11. With the above arrangement, when the lifting motor 162 is started, the drive belt slides between the driving wheel and the driven wheel, thereby driving the linkage block 111 to slide synchronously, thereby causing the lifting plate 11 to rise and fall along the translation plate 16.

[0037] It should be noted that in the prior art, when placing the upper and lower chips, the manipulator places them directly. This will result in a trace amount of air being locked between the two chips during placement. This will cause defects in the internal bonding part of the chip during subsequent bonding. In order to solve the above problem, in this embodiment, an adjustment member 3 is provided on one side of the material picking chuck 2, and the adjustment member 3 is elastically connected to the material picking chuck 2. The end of the adjustment member 3 extends to the bottom of the material picking chuck 2 so that the material picking chuck 2 is tilted to one side. Through the above arrangement, when the material picking chuck 2 clamps the workpiece, the workpiece is tilted, and when placing the workpiece, the workpiece is kept in an inclined state and fits with another chip. Then the material picking chuck 2 drives the workpiece to rotate gradually until it is leveled. In this way, it can be avoided that when the two workpieces are in contact, there is air inside that is not discharged in time, resulting in a reduction in the subsequent bonding quality.

[0038] To achieve the above effects, in this embodiment, the material handling chuck 2 preferably includes a fixed base 21 and an extension tube 22. The bottom of the extension tube 22 is suitable for mounting a block 23. The block 23 is suitable for engaging with a workpiece to carry the workpiece. One end of the block 23 is hinged to the extension tube 22, and the other end is freely disposed. At the same time, one end of the adjusting member 3 is connected to the fixed base 21, and the other end is connected to the block 23. The adjusting member 3 extends below the extension tube 22 to tilt the block 23. Through the above arrangement, the adjusting member 3 can push the block 23 downward, so that under normal conditions, one side of the block 23 is in contact with the extension tube 22 and the other side is tilted downward. When clamping a workpiece, the tilted side of the block 23 first contacts the workpiece, at which point the block 23 cannot clamp the workpiece. The workpiece pushes the tilted side of the block 23 upward, causing it to swing upward until the block 23 returns to a horizontal position. At this time, the workpiece and the block 23 correspond to each other, thereby clamping the workpiece. In this embodiment, preferably, the adjusting member 3 is a telescopic spring.

[0039] In order to assist the clamping block 23 in clamping the workpiece and prevent the workpiece from falling off the clamping block 23 during transportation, in this embodiment, as a preference, the material-retrieving mechanism 1 further includes a clamping cylinder 14 and two clamping jaws 15. The clamping cylinder 14 is mounted on the lifting plate 11, and the two clamping jaws 15 are mounted on the movable end of the clamping cylinder 14, and the two clamping jaws 15 are respectively located on both sides of the clamping block 23. With the above arrangement, after the clamping block 23 is engaged with the workpiece, the clamping cylinder 14 can drive the two clamping jaws 15 to clamp the workpiece from both sides, thereby ensuring that the workpiece will not fall off the clamping block 23 during transportation.

[0040] In order to prevent the material chuck 2 from crushing the workpiece when taking and placing the material, in this embodiment, as an option, a limit seat 12 and a matching spring 13 are provided on the lifting plate 11. The limit seat 12 is installed on the lifting plate 11, and the fixed seat 21 is sleeved on the bottom of the limit seat 12, and the two ends of the matching spring 13 are respectively connected to the limit seat 12 and the fixed seat 21. Through the above arrangement, the clamping block 23 is in contact with the workpiece, and after rotating to a horizontal position, the clamping block 23 pushes the extension tube 22 and the fixed seat 21 to contract the matching spring 13. Through the above arrangement, after the clamping block 23 abuts the workpiece, it will not make hard contact with the workpiece. Instead, the clamping block 23 and the material chuck 2 will contract through the matching spring 13, thereby protecting the workpiece from being crushed.

The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional means in the field and should not be regarded as the inventive point of this utility model patent.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
