Description

Technical Field

[0001] The utility model belongs to the technical field of chip loading, and more specifically, relates to a material pushing mechanism and marking equipment. Background Art

[0002] IC chip packages are often loaded from a magazine. The package must be ejected from the magazine without damaging it before proceeding to the next stage. Currently, common ejection mechanisms in the market often use a pneumatic cylinder as the power source, supplemented by springs or magnets for overload protection. This mechanical structure requires significant space, and the cylinder can only move back and forth between its initial and final positions, unable to stop midway. Therefore, if the package becomes stuck, the cylinder cannot be stopped immediately, potentially damaging the package. Utility Model Content

[0038] The utility model provides a pushing mechanism for pushing a workpiece to move. For example, when the pushing mechanism is used in a marking device, the pushing mechanism can push the workpiece out of a material box so as to facilitate subsequent marking on the workpiece.

[0039] In some embodiments, the workpiece may be an IC chip package, and the pushing mechanism may push the package out of the magazine to facilitate subsequent marking of the package.

[0040] Combine Figure 1 and Figure 2 A pushing mechanism includes a base 100, a connecting rod structure 200, a driving motor 300, a pushing structure 400 and a pressure sensor 500.

[0041] The connecting rod structure 200 has a first end and a second end. The first end of the connecting rod structure is connected to the rotating shaft of the drive motor 300. The second end of the connecting rod structure 200 is slidably arranged on the base 100 along the first direction. The connecting rod structure 200 is used to convert the rotational motion of the drive motor 300 into linear motion.

[0042] Specifically, when the rotating shaft of the driving motor 300 rotates, the first end of the connecting rod structure 200 rotates along with the rotating shaft. At this time, the connecting structure can convert the rotational motion of the first end into linear motion of the second end of the connecting rod structure 200, even if the second end can slide on the base 100 to push the workpiece.

[0043] The pushing structure 400 is disposed at the second end of the connecting rod structure 200 through the pressure sensor 500 and can move along the first direction along with the second end.

[0044] Specifically, when the second end of the connecting rod structure 200 moves in the first direction, the pressure sensor 500 and the pushing structure 400 connected with the pressure sensor 500 can be driven to move in the first direction, and the pushing structure 400 can push the workpiece in the first direction.

[0045] It can be understood that, according to the principle that forces act on each other, when the pushing structure 400 pushes the workpiece, the workpiece can simultaneously generate a reaction force on the pushing structure 400, and the pressure sensor 500 can detect the size of the reaction force of the workpiece on the pushing structure 400. When the reaction force exceeds a preset value, it can be judged that the workpiece is stuck.

[0046] Further, the pressure sensor 500 is connected with the driving motor 300 through a control device (not shown in the figure) to feed back the size of the reaction force on the pushing structure 400 in real time, and the control device can control whether the driving motor 300 needs to stop working, that is, whether the pushing structure 400 continues to push the workpiece in real time.

[0047] It can be understood that, in the present application, the driving power source of the pushing structure 400 is the driving motor 300, so the driving motor 300 can be controlled in real time according to the detection data of the pressure sensor 500 to continue to rotate, and the pushing structure 400 can be controlled in real time whether to continue to push the workpiece.

[0048] That is, in the pushing mechanism of the present application, the driving motor 300 cooperates with the connecting rod structure 200 to drive the pushing structure 400 to move in the first direction to push the workpiece, and the pressure sensor 500 is arranged between the pushing structure 400 and the connecting rod structure 200. The size of the reaction force of the workpiece on the pushing structure 400 detected by the pressure sensor 500 in real time can control whether the driving motor 300 works in real time, and the pushing structure 400 can be controlled in real time whether to continue to push the workpiece to avoid damaging the workpiece. In addition, the driving motor 300 and the connecting rod structure 200 form a driving device, which can be arranged on the side of the pushing structure 400, avoiding the driving device and the pushing structure 400 arranged on the same straight line to cause the pushing mechanism to have a large volume and occupy a large space. Therefore, the pushing mechanism of the present application has a small volume and occupies a small space.

[0049] Referring to Figure 2The connecting rod structure 200 may include a connecting rod 210, a follower wheel 220, and a rocker arm 230. The connecting rod 210 is disposed on the base 100 and is slidable in a first direction. The pressure sensor 500 is disposed on the connecting rod 210 and is movable along the first direction with the connecting rod 210. A sliding groove 211 is provided on the connecting rod 210 along a second direction, which is perpendicular to the first direction. The follower wheel 220 is slidably disposed within the sliding groove 211 and is connected to the rotating shaft of the drive motor 300 via the rocker arm 230. In the above structure, the position of the connecting rod 210 corresponds to the first end of the connecting rod structure 200, and the position of the rocker arm 230 corresponds to the second end of the connecting rod structure 200.

[0050] Specifically, when the rotating shaft of the driving motor 300 rotates, it drives the rocker arm 230 to rotate. When the rocker arm 230 rotates, the follower wheel 220 set on the rocker arm 230 moves along the second direction in the slide groove 211 of the connecting rod 210 and simultaneously drives the connecting rod 210 to move along the first direction. When the connecting rod 210 moves along the first direction, it drives the pressure sensor 500 and the pushing structure 400 connected to the pressure sensor 500 to move.

[0051] In some embodiments, one end of the connecting rod 210 is connected to the rotating shaft of the driving motor 300 , and the other end of the connecting rod 210 is connected to the follower wheel 220 .

[0052] See Figure 1 The pushing mechanism may further include a mounting base 600, and the pressure sensor 500 is disposed on the connecting rod 210 via the mounting base 600. The above structure can facilitate the installation of the pressure sensor 500 and the pushing structure 400.

[0053] Furthermore, in some embodiments, in order to facilitate the installation of the follower wheel 220 and the mounting base 600 and the connecting rod 210, and to avoid interference between the mounting base 600 and the rocker 230, the rocker 230 can be located on the side of the connecting rod 210 close to the base 100, and the mounting base 600 can be located on the side of the connecting rod 210 away from the base 100. Figure 1 As shown, the swing link 230 may be located on one side of the lower surface of the connecting rod 210 , and the mounting seat 600 may be mounted on the upper surface of the connecting rod 210 .

[0054] Furthermore, the mounting base 600 provided on the connecting rod 210 can cover the chute 211. It is understandable that the mounting base 600 covering the chute 211 can avoid affecting the movement of the follower wheel 220 in the chute 211, so as to ensure the stability of the movement of the follower wheel 220, and thus ensure the stability of the movement of the connecting rod 210.

[0055] Furthermore, an adjustment hole 610 may be provided on the mounting seat 600 , and the adjustment hole 610 extends along the second direction. The connecting rod 210 is connected to the mounting seat 600 through the fixing piece passing through the adjustment hole 610 .

[0056] Specifically, the adjustable hole 610 can conveniently adjust the position of the mounting base 600 on the connecting rod 210 in the second direction, and further adjust the position of the pushing structure 400 in the second direction to ensure that the pushing structure 400 can push materials accurately.

[0057] See Figure 1 In some embodiments, the pushing mechanism may further include a limit member 700, which is set on the base 100 corresponding to the initial position and the end position of the connecting rod 210 when it moves along the first direction, and is used to stop the connecting rod 210 to achieve a hard limit on the movement of the pushing structure 400 along the first direction.

[0058] See Figure 1 In some embodiments, in order to make the pushing mechanism more compact, a clearance groove 212 may be further provided on the connecting rod 210 , and the side wall of the clearance groove 212 is used to abut against the limiting member 700 .

[0059] It is understandable that when the limiting member 700 is used to hold the connecting rod 210 in position, the limiting member 700 can be accommodated in the air-avoiding groove 212 , which can not only not affect the movement stroke of the connecting rod 210 but also achieve the limiting function.

[0060] See Figure 1 The pusher structure 400 may include a main body 410 and a pusher portion 420. The main body 410 is connected to the pressure sensor 500. The pusher portions 420 are arranged on the main body 410 in a second direction relative to each other. The pusher portions 420 extend in the first direction to form pusher ends. The above structure can ensure the stability of the pusher portion 420 by pushing the workpiece simultaneously with the opposite pusher portions 420, ensuring that the workpiece is pushed out stably.

[0061] It can be understood that when the relatively arranged pushing parts 420 cooperate to push the workpiece, it is possible to prevent the workpiece from shifting to one side during pushing, thereby improving the stability of pushing.

[0062] Furthermore, the end surface of the pushing end may be provided with a pushing groove 430 extending along the second direction. The pushing groove 430 clamps the workpiece when the pushing portion 420 contacts the workpiece to improve the stability of the workpiece movement during the pushing process.

[0063] See Figure 1 and Figure 2 The pushing mechanism may further include a sliding structure 800 , and the connecting rod 210 is disposed on the base 100 through the sliding structure 800 and can move along the first direction on the sliding structure 800 .

[0064] For example, the sliding structure 800 can include a sliding rail 810 and a sliding block 820, the sliding rail 810 is arranged on the base 100, and the connecting rod 210 is arranged on the sliding rail 810 through the sliding block 820, so that the connecting rod 210 is stably moved along the first direction on the base 100.

[0065] Referring to Figure 1 , the sliding structure 800 can further include a displacement sensor 900, the displacement sensor 900 includes a sensing part 910 and a sensed part 920, the sensing part 910 is arranged on the base 100 and connected with the control device, and the sensed part 920 is arranged on the second end of the connecting rod structure 200 and can move along the first direction with the second end, the sensing part 910 is used for sensing the position of the sensed part 920, so as to determine the position of the pushing structure 400.

[0066] Specifically, in order to facilitate the installation of the sensed part 920, the sensed part 920 can be arranged on the mounting seat 600.

[0067] In addition, the application also provides a marking equipment, which includes a laser and a pushing mechanism, the laser is arranged on one side of the pushing mechanism and is used for marking the workpiece pushed out by the pushing structure 400.

[0068] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection range of the utility model.
