[0003] The rapid development of the semiconductor industry over the years has resulted in the emergence of diverse equipment, often with similar mechanisms. For example, processing equipment such as wafer saws and splitters all feature a retrieving mechanism for retrieving material from a magazine. The gripper of a retrieving mechanism is typically driven in a variety of ways, such as using a pneumatic cylinder to push out and clamp, then retract and release; or using a slide cylinder to extend and raise, then retract and lower. However, current retrieving mechanisms rely on a drive unit to directly actuate the gripper. Therefore, the gripper's clamping and release positions are susceptible to the accuracy of the drive unit itself. This can be particularly noticeable after long-term operation, when wear and tear of the drive unit can lead to significant discrepancies. Summary of the Invention

[0020] In a possible implementation, the material taking mechanism further includes a sensing component, and the sensing component includes:

[0021] A sensor sheet is provided on the sliding member

[0022] A detection device is provided on the support member, and the sensing sheet is used to trigger the detection device when the driving assembly drives the first locking member to put the clamping jaw assembly in a released position.

[0023] In one possible implementation, the clamping jaw assembly includes a movable jaw portion and a fixed jaw portion, the movable jaw portion is transmission-connected to the second locking member, the second locking member is used to drive the movable jaw portion to reciprocate along a second direction relative to the fixed jaw portion to clamp or release the clamping jaw assembly, and the material picking mechanism includes a limiting mechanism arranged on the movable jaw portion along the second direction, the limiting mechanism adjusts the clamping space between the movable jaw portion and the fixed jaw portion when the clamping jaw assembly is in a state of releasing the workpiece, and the clamping space is used to clamp the workpiece.

[0024] In one possible implementation, the limiting mechanism includes a limiting block that is adjustably arranged on the movable claw portion along the second direction, and the limiting block controls the gap between the movable claw portion and the fixed claw portion by contacting and cooperating with the fixed claw portion when the clamping jaw assembly is in a released position.

DETAILED DESCRIPTION

[0035] One aspect of the present application is to provide a material picking mechanism, the structural design of which makes the clamping and releasing positions of its jaws less susceptible to the accuracy of the driving device itself, thereby improving the clamping accuracy of the jaws and the stability of long-term operation.

[0036] Another aspect of the present application is to provide a processing device including the above-mentioned material taking mechanism.

[0037] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] Please refer to Figures 1 and 2. Figure 1 is a structural schematic diagram of the material taking mechanism provided in an embodiment of the present application, and Figure 2 is a cross-sectional view of the material taking mechanism provided in an embodiment of the present application.

[0039] The embodiment of the present application discloses a material taking mechanism, which includes a first locking member 6, a second locking member 7, a clamping jaw assembly 5 and a direction-changing transmission structure.

[0040] Among them, the first locking member 6 can reciprocate along the first direction, and the second locking member 7 can reciprocate along the second direction. The first direction intersects with the second direction. In the embodiment of the present application, the first direction is perpendicular to the second direction. Of course, it should be noted that in other embodiments, the first direction and the second direction can also adopt other angles. The clamping jaw assembly 5 is transmission-connected to the second locking member 7, and the second locking member 7 reciprocates along the second direction to drive the clamping jaw assembly 5 to clamp or release.

[0041] The first locking member 6 and the second locking member 7 cooperate through a direction-changing transmission structure to convert the reciprocating motion of the first locking member 6 in a first direction into the reciprocating motion of the second locking member 7 in a second direction. The direction-changing transmission structure converts the motion of the first locking member 6 in the first direction into the motion of the second locking member 7 in the second direction. For example, the direction-changing transmission structure can be implemented by the cooperation of a roller and an inclined surface, or other structures capable of converting motion in different directions.

[0042] It can be seen that compared with the prior art, the material-retrieving mechanism provided in the embodiment of the present application does not directly act on the clamping jaw assembly 5 through an external force (such as the driving assembly in the prior art) when it is used, but utilizes the first locking member 6, the second locking member 7 and the direction-changing transmission structure between the first locking member 6 and the second locking member 7 for transmission cooperation, that is, when the first locking member 6 moves in the first direction toward the direction of the clamping jaw assembly, the first locking member 6 can drive the second locking member 7 to move along one side of the second direction through the direction-changing transmission structure to drive the clamping jaw assembly 5 to clamp; when the first locking member 6 moves away from the clamping jaw assembly in the first direction, the first locking member 6 can drive the second locking member 7 to move along the other side of the second direction through the direction-changing transmission structure ( One side is opposite to the other direction), thereby loosening the clamping jaw assembly 5. The first locking member 6, the second locking member 7 and the direction-changing transmission structure adopt a stable and reliable pure mechanical structure, and do not directly drive the clamping jaw assembly, but transmit power through the direction-changing transmission structure. Compared with the more complex driving assembly that directly drives the clamping jaw assembly, its accuracy and consistency are easier to guarantee. Therefore, the above-mentioned transmission structure is simple and easy to process, and can avoid the driving assembly from directly acting on the clamping jaw assembly 5, thereby avoiding the accuracy of the relatively complex driving assembly from having an adverse effect on the accuracy of the clamping jaw assembly 5, and improving the consistency of the clamping and releasing positions of the clamping jaw assembly 5 each time, thereby improving the clamping accuracy of the clamping jaw and the stability of long-term operation.

[0043] The above-mentioned material picking mechanism also includes a driving component 1, which is transmission-connected to the first locking member 6. The driving component 1 is used to drive the first locking member 6 to move back and forth along the first direction. The first locking member 6 and the second locking member 7 are transmission-coordinated through a changing transmission structure to convert the reciprocating motion of the first locking member 6 along the first direction into the reciprocating motion of the second locking member 7 along the second direction.

[0044] As shown in Figure 2, in an embodiment of the present application, the direction-changing transmission structure includes a transmission surface 601 and a transmission roller 8, wherein the transmission surface 601 is arranged on one of the first locking member 6 and the second locking member 7, and the transmission surface 601 is inclined. The transmission surface 601 can be a plane or a smooth curved surface. If the transmission surface 601 is a smooth curved surface, the inclined setting of the smooth curved surface means that the two ends of the smooth curved surface are not in the same plane parallel to the first direction, and the connecting line of the two ends of the transmission surface 601 is set at an angle to the first direction and the second direction respectively. The transmission roller 8 is arranged on the other of the first locking member 6 and the second locking member 7, and the transmission inclined surface cooperates with the transmission roller 8 to convert the reciprocating movement of the first locking member 6 along the first direction into the reciprocating movement of the second locking member 7 along the second direction.

[0045] Specifically, as shown in the embodiment of Figure 2, the transmission surface 601 is provided on the first locking member 6, and the transmission roller 8 is provided on the second locking member 7. At the same time, in order to ensure that the target object is subjected to uniform and consistent force, the transmission surface 601 is an inclined plane. In this way, as long as the driving component 1 drives the first locking member 6 to move in the first direction at a certain speed, the speed of movement of the second locking member 7 in the second direction is also certain, which can ensure that the clamping jaw assembly 5 is clamped or released at a uniform speed.

[0046] To further optimize the above technical solution, in an embodiment of the present application, as shown in Figure 2, the above-mentioned direction-changing transmission structure also includes a locking surface 602, which is arranged at an end of the transmission surface 601 away from the clamping jaw assembly and connected to the transmission surface 601. The locking surface 602 is parallel to the first direction. When the transmission roller 8 rolls along the transmission surface 601, the transmission surface 601 can convert the movement of the first locking member 6 along the first direction into the movement of the second locking member 7 along the second direction. When the transmission roller 8 rolls along the transmission surface 601 to the locking surface 602, that is, because the locking surface 602 is parallel to the first direction, even if the driving assembly 1 continues to move along the first direction, as long as the transmission roller 8 is still cooperated with the locking surface 602, the clamping jaw assembly 5 can be kept in the clamping position. At this time, the first locking member 6 and the second locking member 7 are in a dead point position, thereby avoiding the problem of material falling during the transportation of the sheet.

[0047] As shown in Figures 1 and 2, in an embodiment of the present application, the material picking mechanism also includes a support member 2, a sliding member 3 and an elastic reset member, wherein the support member 2 is used to provide an installation position and support for the fixed claw portion 502 of the clamping jaw assembly 5, the driving assembly 1 and the sliding member 3. Of course, the support member 2 can adopt an integrated structure or a split structure. The sliding member 3 can be arranged on the support member 2 to slide back and forth along the second direction. In this case, the sliding member 3 is installed on the support member 2 through a linear guide rail 9, the second locking member 7 is arranged on the sliding member 3, the movable claw portion 501 of the clamping jaw assembly 5 is arranged on the sliding member 3, and the elastic reset member is arranged between the support member 2 and the sliding member 3. The elastic reset member is used to drive the sliding member 3 to reset relative to the support member 2 when the driving assembly 1 drives the first locking member 6 to reset.

[0048] In order to accurately obtain the position information of the clamping jaw assembly 5, in an embodiment of the present application, the above-mentioned material picking mechanism also includes a sensing component 4, the sensing component 4 includes a sensing sheet 401 and a detection device 402, wherein the sensing sheet 401 is arranged on the sliding member 3, and the detection device 402 is arranged on the support member 2, the sensing sheet 401 is used to trigger the detection device 402 when the driving component 1 drives the first locking member 6 to make the clamping jaw assembly 5 in a released position, and the detection device 402 includes but is not limited to a photoelectric sensor, a proximity switch, a Hall element, etc. In an embodiment of the present application, the detection device 402 is a photoelectric sensor. When the clamping jaw assembly 5 is in the released position, the distance between the sensing sheet 401 and the detection device 402 is the shortest. At this time, the detection device 402 can detect the sensing sheet 401, indicating that the clamping jaw assembly 5 is in an open state at this time. When the driving component 1 drives the first locking member 6 to cooperate with the second locking member 7 to clamp the clamping jaw assembly 5, the sensing sheet 401 is away from the detection device 402. When the detection device 402 cannot detect the sensing sheet 401, the clamping jaw assembly 5 is in a clamped position.

[0049] As shown in Figures 1 and 2, in the embodiment of the present application, the clamping jaw assembly 5 includes a movable jaw portion 501 and a fixed jaw portion 502, wherein the movable jaw portion 501 is in transmission connection with the second locking member 7, and the second locking member 7 is used to drive the movable jaw portion 501 to reciprocate relative to the fixed jaw portion 502 along the second direction to clamp or release the clamping jaw assembly 5, and a clamping gap is formed between the facing surfaces of the movable jaw portion 501 and the fixed jaw portion 502. The material picking mechanism also includes a limiting mechanism provided on the movable jaw portion 501 along the second direction. The limiting mechanism adjusts the clamping space between the movable jaw portion 501 and the fixed jaw portion 502 when the clamping jaw assembly is in a state of releasing the workpiece to accommodate materials of different specifications. The clamping space is used to clamp the workpiece.

[0050] As shown in Figures 1 and 2, in an embodiment of the present application, the limiting mechanism includes a limiting block 503 that is adjustably arranged on the movable claw portion 501 along the second direction. When the clamping jaw assembly 5 is in the released position, the limiting block 503 controls the gap between the movable claw portion 501 and the fixed claw portion 502 by contacting and cooperating with the fixed claw portion 502. When the clamping jaw assembly 5 is in the released position, the lower edge of the limiting block 503 cooperates with the side surface of the fixed claw portion 502 away from the movable claw portion 501 to limit the clamping gap between the movable claw portion 501 and the fixed claw portion 502. Therefore, by adjusting the position of the limiting block 503 on the movable claw portion 501, the clamping gap between the movable claw portion 501 and the fixed claw portion 502 can be adjusted.

[0051] Specifically, in an embodiment of the present application, the above-mentioned limit block 503 is set on the movable claw portion 501 through a threaded fastener, and one of the limit block 503 and the movable claw portion 501 is provided with a bar hole, the length direction of the bar hole is the second direction, and the other of the limit block 503 and the movable claw portion 501 is provided with a threaded hole, and the threaded fastener passes through the bar hole and cooperates with the threaded hole.

[0052] In an embodiment of the present application, the drive component 1 can adopt a variety of structures. For example, the drive component 1 can be a piston cylinder, such as a pneumatic cylinder or a hydraulic cylinder, or the drive component 1 can be a linear motor, or the drive component 1 includes a rotary motor and a transmission mechanism, which is used to convert the rotation output by the rotary motor into a linear reciprocating motion. The transmission mechanism includes but is not limited to a screw slider mechanism, a gear rack mechanism, and a cam connecting rod mechanism.

[0053] An embodiment of the present application also provides a processing device, which includes a material-taking mechanism as described in the above embodiment. Since the processing device adopts the material-taking mechanism in the above embodiment, the technical effects of the processing device please refer to the above embodiment.

[0054] Preferably, in an embodiment of the present application, the processing device is a wafer splitting machine. Of course, it should be noted that the processing device is not limited to a wafer splitting machine.
