[0002] In the semiconductor packaging process, various types of components need to be transported and moved to different processes or workstations.

[0003] To minimize damage or contamination to the workpiece, vacuum suction nozzles are typically used for adsorption and gripping. Vacuum adsorption requires a certain area of ​​adsorption surface on the workpiece. However, for some... Figure 1 The special workpiece 10 shown is difficult to adsorb using conventional vacuum nozzles. Because the workpiece 10 is cage-shaped with multiple parallel metal prongs at the bottom, it creates planes of varying depths inside. When adsorbed using a conventional nozzle, the nozzle cannot make contact with a suitable plane, making it difficult to grasp. Utility Model Content

[0012] Preferably, the guide slope is provided with an elastic structure, which is used to abut against the upper side of the workpiece sidewall.

[0013] By adopting the above technical solution, after the bottom of the workpiece is attached to the lower side of the blade block, the elastic structure has potential energy after deformation.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1: Refer to Figure 2 Embodiment 1 of this application discloses a blade-shaped suction head, including a robotic arm 100. The robotic arm 100 is connected to a gripping block 110. The gripping block 110 has several blade-shaped blocks 111 on the side near the workpiece. In this embodiment, three blade-shaped blocks 111 are arranged to match the workpiece. The multiple blade-shaped blocks 111 are arranged at intervals and are used to embed into the protrusions of the workpiece. It is worth noting that the width of the blade-shaped blocks 111 is smaller than the gap between the protrusions inside the workpiece. In this embodiment, the robotic arm 100 is a general robotic arm structure capable of three-axis motion, which will not be described in detail here.

[0033] Reference Figure 3 , Figure 4The cutter block 111 has an air passage 112, which is vertically arranged and extends through the bottom of the cutter block 111 to form a suction hole 113. Multiple air passages 112 are spaced apart within the cutter block 111 to form multiple suction holes 113 along the length of the cutter block 111. The suction holes 113 will contact the bottom of the workpiece, thereby adsorbing it.

[0034] Each blade block 111 has a concave air cavity 120 on the side near the gripping block 110. The air cavity 120 is connected to multiple air channels 112. The gripping block 110 has an air extraction channel 121 corresponding to the blade block 111. In this embodiment, there are three air extraction channels 121.

[0035] When the gripping block 110 is moved downward by the robotic arm 100, guide ramps 122 on both sides of the gripping block 110 are provided to guide the workpiece. These ramps will abut against the upper part of the workpiece sidewall, allowing the cutting block 111 to be accurately inserted into the workpiece. In this embodiment, only the guide ramps 122 are on both sides; in other embodiments, the guide ramps 122 may be on all four sides. To prevent the cutting block 111 from damaging internal components of the workpiece, chamfers 123 are provided on both sides of the cutting block 111 along its width to provide guidance and avoidance.

[0036] The implementation principle of Embodiment 1 of this application is as follows: The robotic arm 100 moves the gripping block 110 downwards, and the cutting edge block 111 first enters the workpiece. Then, the guide ramp 122 contacts the side wall of the workpiece, thereby straightening the workpiece. Subsequently, the cutting edge block 111 is embedded into the workpiece and penetrates between the inserts inside the workpiece, finally causing the suction hole 113 to abut against the bottom of the workpiece. Then, the suction channel 121 creates a negative pressure at the suction hole 113, thereby enabling the workpiece to be gripped and moved effectively.

[0037] Example 2: Refer to Figure 5 , Figure 6 The difference from Embodiment 1 is that an elastic structure is provided on the guide slope 122, which is used to abut against the upper side of the workpiece sidewall. The elastic structure includes a spring 124 and a pressing plate 125. The guide slope 122 has a receiving groove 126 in the vertical direction. The spring 124 is disposed in the receiving groove 126. One end of the spring 124 is fixed to the bottom of the receiving groove 126, and the other end is fixed to the pressing plate 125. The pressing plate is used to abut against the sidewall of the workpiece.

[0038] After the gripping block 110 moves and the suction hole 113 is about to contact the bottom of the workpiece, the upper side of the workpiece sidewall will abut against the pressure plate 125, thereby compressing the spring 124. When the gripping block 110 needs to be released, the spring 124 will extend outward to push the workpiece away so that the two can be separated better.

[0039] To ensure greater stability of the pressing block during movement, the pressing plate 125 also has a guide tube 127, which is inserted into the receiving groove 126, and the spring 124 is embedded in the guide tube 127. In this embodiment, the spring 124 and the guide tube 127 extend out of the receiving groove 126 to obtain a range of motion. Furthermore, the side of the pressing block near the guide slope 122 is flush with the outer wall of the guide tube 127, while the other side extends outward to avoid contact with the guide slope 122 during movement.

[0040] Example 3: Reference Figure 7 , Figure 8 The difference from Embodiment 1 is that an elastic structure is provided on the guide slope 122, which is used to abut against the upper side of the workpiece sidewall. The elastic structure includes an arc-shaped spring piece 130, and the guide slope 122 has a concave relief groove 131. One end of the spring piece 130 is connected to the inner wall of the relief groove 131. The protruding portion of the spring piece 130 protrudes outward, and the free end of the spring piece 130 bends and extends into the relief groove 131.

[0041] In this embodiment, when the sidewall of the workpiece is relatively close to the spring 130, since the end of the spring 130 is located within the relief groove 131, it will move and abut against the outside of the spring 130. At this time, the spring 130 will retract and deform within the relief groove 131. When it needs to be disengaged, the outward expansion of the spring 130 will help the suction hole 113 disengage from the workpiece. In this embodiment, the spring 130 is made of elastic metal.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
