Description

Technical Field

[0001] This utility model relates to the field of assembly technology, specifically to a workpiece clamping and flipping mechanism. Background Technology

[0002] For assembly systems, assembly efficiency and placement accuracy are two important indicators.

[0003] In the chip manufacturing process, magnets need to be precisely connected to pins (leads), as one or more pins need to be mounted on a single mounting surface of the magnet. The traditional mounting process typically includes the following key steps: applying adhesive to the mounting position on the magnet's mounting surface, and then mounting the pins to the corresponding mounting positions after the adhesive is applied.

[0004] In existing technologies, magnets are usually flipped manually. However, manual operation makes it difficult to guarantee the accuracy and consistency of each flip, which may lead to deviations in parameters such as the position and angle of the magnet after flipping, thus affecting the subsequent mounting accuracy. In addition, compared with automated flipping equipment, manual flipping of magnets is slower, less efficient, and results in low production efficiency. Utility Model Content

Each clamping part is rotatably connected to a clamping head, which is connected to a rotary cylinder. The clamping head clamps the workpiece and is driven by the rotary cylinder to flip the workpiece around the Y-axis.

[0015] According to one embodiment of the present invention, a connecting shaft is installed at the rear of the clamping head, the connecting shaft is connected to the output end of the rotary cylinder, and the connecting shaft translates within the output end and is driven to rotate by the output end.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] like Figure 1 and Figure 2As shown, the workpiece clamping and flipping mechanism of this utility model embodiment includes: a bearing component 1 and a flipping component 2.

[0034] Specifically, the carrier component 1 moves between a first position and a second position on the Z-axis (in this embodiment, the vertical direction is defined as the Z-axis for ease of explanation, and the actual movement direction and setting direction of the carrier component 1 are not limited). The first position refers to the position where the workpiece 4 to be transported is located. The second position refers to the position where the carrier component 1 lifts the workpiece 4 to a position awaiting flipping.

[0035] Furthermore, the support assembly 1 includes a stage 11 that moves between a first position and a second position on the Z-axis, and the stage 11 is provided with a workpiece groove 111 for placing the workpiece 4.

[0036] Preferably, the shape of the workpiece groove 111 matches the workpiece 4, and the size of the workpiece groove 111 is slightly larger than that of the workpiece 4, so as to avoid interference between the workpiece 4 and the workpiece groove 111, and avoid friction and collision that could damage the workpiece 4.

[0037] Specifically, the end of the workpiece groove 111 is provided with a machining process hole to facilitate the machining and forming of the workpiece groove 111.

[0038] Specifically, the stage 11 is mounted on the Z-axis slide cylinder 12, and the Z-axis slide cylinder 12 drives the stage 11 to move between a first position and a second position on the Z-axis.

[0039] Specifically, workpiece 4 is placed on the workpiece slot 111 of the stage 11 and moves with the stage 11 between a first position and a second position. Here, workpiece 4 is a magnet.

[0040] Specifically, the flipping component 2 can move toward the workpiece 4 to clamp the workpiece 4 located in the second position. After the flipping component 2 clamps the workpiece 4, it can drive the workpiece 4 to flip around the Y-axis (in this embodiment, the left and right directions are defined as the Y-axis for ease of explanation, and the movement direction and setting direction of the flipping component 2 are not actually limited) to realize the flipping of the workpiece 4. After the flipping is completed, the flipping component 2 moves away from the workpiece 4 to release the workpiece 4.

[0041] Furthermore, the flipping assembly 2 includes two clamping parts 21 that move along the Y-axis away from or towards the workpiece 4, each clamping part 21 being rotatably connected to a clamping head 211. The clamping head 211 is connected to a rotary cylinder 22. The clamping part 21 is mounted on a Y-axis slide cylinder 23, which drives the clamping part 21 to move along the Y-axis. The clamping head 211 clamps the workpiece 4 and is driven by the rotary cylinder 22 to flip the workpiece 4 around the Y-axis. One of the two clamping heads 211 is the active action and the other is the driven action, thus ensuring accurate flipping of the workpiece 4. Generally, the workpiece is flipped according to the mounting requirements of the mounting surface of the workpiece 4. In this embodiment, the workpiece is square, and the flipping angle of the workpiece 4 is generally 90°.

[0042] Specifically, the stage 11 moves along the Z-axis to the second position, and the workpiece 4 also reaches the second position simultaneously. At this time, the Y-axis slide cylinder 23 drives the clamping part 21 to move along the Y-axis to the workpiece 4 until the clamping head 211 clamps the workpiece 4. Then, the stage 11 moves along the Z-axis away from the second position, and the workpiece 4 separates from the stage 11. At this time, the rotary cylinder 22 starts, driving the clamping head 211 to rotate. The clamping head 211 drives the workpiece 4 to rotate synchronously, and stops after rotating to the required angle. The stage 11 moves back to the second position to receive the workpiece 4, and then the Y-axis slide cylinder 23 drives the clamping part 21 to reset and release the workpiece 4, completing one rotation of the workpiece 4. The rotated workpiece 4 waits on the stage 11 for the external mounting device to pick it up and enter the next process.

[0043] Preferably, a connecting shaft 24 is installed behind the clamping head 211. The connecting shaft 24 is connected to the output end 211 of the rotary cylinder 22, and the connecting shaft 24 translates along the Y-axis within the output end 221 and is driven to rotate around the Y-axis by the output end 211. The output end 221 is provided with a connecting hole 222, within which the connecting shaft 24 can translate along the Y-axis. The connecting shaft 24 is circumferentially limited by the connecting hole 222 on the Y-axis. Through the cooperation of the connecting shaft 24 and the connecting hole 222, the circumferential limitation of the connecting shaft 24 is achieved, ensuring that the rotary cylinder 222 can drive the connecting shaft 24 to rotate. At the same time, in order to ensure that the clamping part 21 can translate on the Y-axis, the connecting shaft 24 can slide within the connecting hole 222, ensuring the freedom of movement on the Y-axis. Of course, a linear bearing can also be used between the rotary cylinder 22 and the connecting shaft 24 to achieve the same effect.

[0044] Furthermore, the carrier component 1 and the flipping component 2 are mounted on the linear motor module 3, which is positioned along the X-axis and drives the carrier component 1 and the flipping component 2 to move along the X-axis (in this embodiment, the front-to-back direction is defined as the X-axis for ease of explanation, and the actual movement direction and setting direction of the linear motor module 3 are not limited). The carrier component 1 and the flipping component 2 are mounted on the mounting base of the linear motor module 3, which is mainly used to transport the workpiece 4 from one process station to another throughout the entire mounting production line.
