Description

Technical Field

[0001] The utility model is mainly used in the field of automatic identification and placement of wafer boxes in the semiconductor industry, and is particularly an automatic identification and placement mechanism. Background Art

[0002] At present, in the integrated circuit manufacturing process, a robot is required to grab the wafer box and transport the wafer box to different locations through a transmission system. However, the pick-and-place mechanism in the existing technology cannot distinguish different types of wafer boxes. The gripper does not alarm when it is empty and continues to run without load. The existing pick-and-place mechanism has only one set of cylinder clamps. When grabbing, the wafer box is not centered, and the wafer box is easy to touch the edge of the box when placed. Therefore, it is urgent to improve the existing pick-and-place mechanism. Summary of the invention

[0003] The utility model aims at the above-mentioned problems existing in the prior art and provides an automatic identification pick-and-place mechanism. The utility model designs an automatic identification pick-and-place mechanism, comprising a connecting flange and a pick-and-place mechanism substrate, characterized in that the connecting flange is installed at the center of the upper surface of the pick-and-place mechanism substrate, an electromagnetic valve is installed on the pick-and-place mechanism substrate, a code reader is installed on one side of the bottom plate of the pick-and-place mechanism substrate, a baffle assembly is installed on each of the four sides of the bottom surface of the pick-and-place mechanism substrate, the baffle assemblies on the four sides face each other, one baffle assembly in a pair of face-to-face baffle assemblies is installed with a photoelectric sensor generating end, and the other baffle assembly is installed with a photoelectric sensor receiving end. The baffle assembly is composed of a side baffle, a side baffle pad and a cylinder with a guide rod, the cylinder with a guide rod is installed on the bottom surface of the pick-and-place mechanism substrate, the guide rod of the cylinder with a guide rod is connected to the side baffle, the cylinder with a guide rod is connected to the electromagnetic valve installed on the pick-and-place mechanism substrate through a speed control valve through a connecting pipe, and the side baffle pad is installed on the inner side of the lower end of the side baffle. The axes of the face-to-face cylinders with guide rods are coaxial, and the axes of the two pairs of face-to-face cylinders with guide rods are perpendicular to each other. Compared with the existing technology, the advantages of the utility model are: 1. Compared with only one set of cylinders in the front and back, the two sets of cylinders in the front, back, left and right can correct the position of the wafer box when it is taken and placed, so that it is convenient to place it in the center of the material box on the conveyor line, avoiding wear or collision with the edge of the material box when the wafer box is placed, thereby damaging the wafer box. 2. The photoelectric sensor detects the wafer box to prevent the robot from malfunctioning due to the empty placement mechanism, avoiding time loss and reducing corporate cost losses. 3. The barcode reader scans the code to realize the flow of different wafer boxes to different conveyor lines, reducing manual identification. 4. The side guard plate is made of high-strength rubber, which effectively prevents scratches on the outer packaging of the wafer box. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0009] It should be noted that the fully described utility model may also have a variety of modified and improved implementation schemes, and is not limited to the specific examples of the above-mentioned implementation schemes. The above-mentioned examples are only used as an illustration of the utility model, not as a limitation of the utility model. In short, the protection scope of the utility model should include those obvious changes or substitutions and modifications to those of ordinary skill in the art, and shall be subject to the attached claims.

[0010] The figure shows an automatic identification pick-and-place mechanism, including a connecting flange 1 and a pick-and-place mechanism substrate 2, characterized in that the connecting flange is installed at the center of the top of the pick-and-place mechanism substrate, a solenoid valve 3 is installed on the pick-and-place mechanism substrate, a code reader 4 is installed on one side of the bottom plate of the pick-and-place mechanism substrate, and a baffle assembly 5 is installed on each of the four sides of the bottom surface of the pick-and-place mechanism substrate. The baffle assemblies on the four sides face each other, and a photoelectric sensor generating end 6 is installed on one of the baffle assemblies in a pair of facing baffle assemblies, and a photoelectric sensor receiving end 7 is installed on the other baffle assembly. The baffle assembly is composed of a side baffle 8, a side baffle pad 9 and a cylinder with a guide rod 10. The cylinder with a guide rod is installed on the bottom surface of the pick-and-place mechanism substrate, and the guide rod 11 of the guide rod cylinder connects the side baffle.

[0011] The guide rod cylinder is connected to the electromagnetic valve installed on the pick-and-place mechanism base plate by the speed control valve 12 through a connecting pipe (not shown in the figure), and the side baffle plate is installed on the inner side of the lower end of the side baffle plate. The axes of the face-to-face guide rod cylinders are coaxial, and the axes of the two pairs of face-to-face guide rod cylinders are perpendicular to each other.

[0012] When in use, the automatic identification pick-and-place mechanism of the utility model is connected by a manipulator 13 through a connecting flange. The photoelectric sensor adopts a counter-radiation type (a group), and the photoelectric sensor transmitting end 6 emits red light or infrared, and the photoelectric sensor receiving end 7 receives it. If an object passes through the light and cuts off, a signal is output. That is, if the pick-and-place mechanism grabs the wafer box 14, the light is cut off, and a signal is output. The front and rear groups of guide rod cylinders in the face-to-face are controlled by the same solenoid valve at the same time, and extend or retract at the same time. When the robot grabs the wafer box, the wafer box may be slightly skewed, and the distance between the front and rear sides and the side block is inconsistent. When the front and rear groups of cylinders are retracted at the same time, the side block will fit with the front and back of the wafer box, and the skew of the wafer box can be corrected. Similarly: the left and right groups of guide rod cylinders in the face-to-face are controlled by another solenoid valve. When the guide rods are retracted at the same time, the side block fits with the two sides of the wafer box, and the wafer box is located at the center of this pick-and-place mechanism. At this time, the wafer box can be grabbed by the robot. Since the position of the wafer box can be corrected at this time, it can be placed in the center of the material box on the conveyor line to avoid wear or collision with the edge of the material box when the wafer box is placed, thereby damaging the wafer box. The photoelectric sensor detects the wafer box, mainly to prevent the robot from malfunctioning due to the empty pick-and-place mechanism. The barcode reader can scan the code to realize the flow of different wafer boxes to different conveyor lines, reducing manual identification. The side guard pad is made of high-strength rubber, which effectively prevents scratches on the outer packaging of the wafer box.
