Description

Technical Field

[0001] This utility model relates to the field of automatic packaging equipment, and more specifically, it relates to a resin flipping feeding mechanism for automatic packaging equipment. Background Technology

[0002] In the semiconductor chip manufacturing process, the traditional resin feeding process has significant technical bottlenecks: First, after the conventional large press uses an independent resin arranging device to arrange the resin material, the carrier loaded with resin material needs to be manually moved to the high-temperature mold station (in the semiconductor packaging process, the vibratory feeder usually arranges the resin material horizontally and is located below the equipment, while the mold injection tank often requires the resin material to be arranged vertically and above the equipment, so manual operation is required). This process is not only inefficient (the processing time for a single batch is about 3-5 minutes), but the high-temperature environment also poses a risk of burns to the operators. Second, with the improvement of the automation level of packaging equipment, the traditional manual feeding method is incompatible with the automatic packaging production line, resulting in an imbalance in the production cycle.

[0003] Therefore, in order to solve the above-mentioned technical problems, this application proposes a resin flipping feeding mechanism for an automatic packaging device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a resin flipping feeding mechanism for automatic packaging equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a resin flipping feeding mechanism for an automatic packaging equipment, comprising a mounting plate disposed next to a vibratory feeder, a guide shaft mounted on the surface of the mounting plate, and synchronous pulleys mounted on the upper and lower sides of the mounting plate beside the guide shaft, with a synchronous belt driven by a drive motor meshing on the outer walls of the two synchronous pulleys, a feeding component disposed on the synchronous belt, and a contact flipping component disposed between the feeding component and the mounting plate, wherein when the synchronous belt drives the feeding component to move vertically along the guide shaft, and the feeding component rises to a preset height, the contact flipping component causes the feeding component to rotate 90° to a vertical state.

[0006] Preferably, the contact flipping component includes a guide block fixed to the upper part of the back of the mounting plate and a guide wheel installed on the back of the feeding component. When the feeding component rises to a preset height, the guide wheel contacts the guide block, causing the feeding component to rotate 90° around the guide shaft to a vertical state.

[0007] Preferably, the guide block is a progressive arc-shaped guide surface, the curvature of which matches the flipping angle of the feeding component, and the radius of curvature of the arc-shaped guide surface gradually decreases from the bottom to the top.

[0008] Preferably, the drive motor is a servo motor with a built-in position feedback module, which can dynamically adjust the speed according to the real-time position of the feeding component.

[0009] Preferably, the synchronous belt is a double-sided toothed synchronous belt, which is fixed to the feeding component by a rigid connector.

[0010] Preferably, the guide wheel is a polyurethane-coated roller, and the ratio of its outer diameter to the width of the contact surface of the guide block is 1:1.2-1.5.

[0011] Preferably, the surface of the guide block is coated with a layer of polytetrafluoroethylene coating with a coating thickness of 0.05 mm to 0.1 mm.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model uses a vacuum adsorption unit on the feeding component to fix the resin material output horizontally from the vibratory plate. The drive motor drives the synchronous belt to move. The synchronous belt moves along the synchronous pulley and drives the feeding component to move vertically along the guide shaft. When the feeding component rises to a preset height, the contact flipping component causes the feeding component to rotate 90° to a vertical position. The robot arm on the automatic packaging equipment grabs the vertically arranged resin material and places it into the injection mold groove. This eliminates manual intervention and the mechanically controlled feeding can be well compatible with the automatic packaging production line. This solves the problem in the prior art where the existing technology requires manual transfer of the resin material tray to the high-temperature mold station, and the traditional manual feeding method is not compatible with high-speed automatic packaging production lines.

[0014] 2. The surface of the guide block of this utility model is coated with a layer of polytetrafluoroethylene coating with a thickness of 0.05mm-0.1mm. This coating has self-lubricating properties, which can reduce the friction between the guide wheel and the guide block, making the turning process of the feeding component smoother and reducing energy loss.

[0015] 3. The synchronous belt of this utility model is a double-sided toothed synchronous belt, which is fixed to the feeding component by a rigid connector. The tooth grooves on both sides of the double-sided toothed synchronous belt can mesh with the synchronous pulley at the same time, which significantly increases the contact area.

[0016] 4. The guide block of this utility model is a progressive arc-shaped guide surface. Its curvature matches the flipping angle of the feeding component. The radius of curvature of the arc-shaped guide surface gradually decreases from the bottom to the top. The gradual curvature design makes the rotational acceleration of the guide wheel change linearly when it contacts the guide block, avoiding the instantaneous impact generated by the traditional right-angle guide surface, ensuring that the feeding component completes the 90° flipping with a smooth angular velocity, and reducing mechanical vibration and noise.

[0022] like Figure 1-3 As shown, this utility model provides a resin flipping feeding mechanism for an automatic packaging equipment, including a mounting plate 1 set next to the vibratory plate. A guide shaft 5 is mounted on the surface of the mounting plate 1, and synchronous wheels 4 are mounted on both the upper and lower sides of the surface of the mounting plate 1 next to the guide shaft 5. A synchronous belt 3 driven by a drive motor 2 is meshed on the outer walls of the two synchronous wheels 4. A feeding component 6 is provided on the synchronous belt 3, and a contact flipping component 7 is installed between the feeding component 6 and the mounting plate 1.

[0023] In use, the vacuum adsorption unit on the feeding component (consisting of a vacuum generator and an adsorption plate; the vacuum generator generates negative pressure through compressed air to provide the adsorption power source; the adsorption plate is integrated at the bottom of the feeding component 6 and communicates with the vacuum generator, with an array of adsorption holes for adsorbing resin material) fixes the resin material output horizontally from the vibratory plate. The drive motor 2 drives the synchronous belt 3 to move, and the synchronous belt 3 moves along the synchronous wheel 4. The synchronous belt 3 drives the feeding component 6 to move vertically along the guide shaft 5. When the feeding component 6 rises to the preset height, the contact flipping component 7 causes the feeding component 6 to rotate 90° to a vertical position. The robot arm on the automatic packaging equipment grabs the vertically arranged resin material and places it into the mold injection groove. Then the feeding component 6 returns to the initial position. During this process, the contact flipping component 7 also causes the angle of the feeding component 6 to become horizontal.

[0024] Furthermore, the contact flipping component 7 includes a guide block 701 fixed to the upper part of the back of the mounting plate 1, and a guide wheel 702 installed on the back of the feeding component 6. When the feeding component 6 rises to a preset height, the guide wheel 702 contacts the guide block 701, causing the feeding component 6 to rotate 90° around the guide shaft 5 to a vertical position. The guide block 701 is a progressive arc-shaped guide surface, the curvature of which matches the flipping angle of the feeding component 6. The radius of curvature of the arc-shaped guide surface gradually decreases from the bottom to the top. The gradual curvature design makes the rotational acceleration of the guide wheel change linearly when it contacts the guide block, avoiding the instantaneous impact generated by the traditional right-angle guide surface, ensuring that the feeding component completes the 90° flipping with a smooth angular velocity, and reducing mechanical vibration and noise.

[0025] Furthermore, the surface of the guide block 701 is coated with a layer of polytetrafluoroethylene (PTFE) with a thickness of 0.05mm-0.1mm. This coating has self-lubricating properties, which can reduce the friction between the guide wheel 702 and the guide block 701, making the flipping process of the feeding component 6 smoother and reducing energy loss. The guide wheel 702 is a polyurethane-coated roller, and the ratio of its outer diameter to the contact surface width of the guide block 701 is 1:1.2-1.5. From the perspective of material properties, polyurethane coating has good elasticity and wear resistance, which can effectively buffer the impact force generated when the guide wheel 702 contacts the guide block 701, reduce vibration and noise, and extend the service life of the guide wheel 702 and the guide block 701. At the same time, its elasticity can better adapt to the progressive arc-shaped guide surface of the guide block 701, ensuring that the guide wheel 702 makes full contact with the guide block 701 during rolling, and achieving a smooth flipping action. From a dimensional perspective, a ratio of 1:1.2 to 1.5 between the outer diameter and the contact surface width provides a suitable contact area. This avoids excessive local pressure due to an insufficient contact area, which could accelerate wear and deformation, while also preventing excessive frictional resistance and reduced motion efficiency due to an excessively large contact area. This design ensures that when the feeding component 6 rises to the preset height, the guide wheel 702 smoothly engages with the guide block 701, guaranteeing that the feeding component 6 rotates accurately and stably 90° around the guide shaft 5 to a vertical position. This improves the working accuracy and reliability of the resin flipping feeding mechanism of the entire automatic packaging equipment.

[0026] In this invention, the synchronous belt 3 is a double-sided toothed synchronous belt, which is fixed to the feeding component 6 by a rigid connector. The tooth grooves on both sides of the double-sided toothed synchronous belt can simultaneously mesh with the synchronous pulley 4, significantly increasing the contact area. When the feeding component 6 is rapidly raised, lowered, or flipped, the double-sided meshing can avoid the "tooth skipping" phenomenon caused by instantaneous impact load on one side of the tooth surface, ensuring a constant transmission ratio (error ≤ 0.01 mm / stroke). The rigid connector (such as an aluminum alloy coupling block) fixes the synchronous belt 3 to the feeding component 6. Compared with traditional flexible connections (such as spring buckles), it can eliminate the displacement lag caused by the elastic deformation of the belt body, keeping the timing error of the raising and lowering actions within a reasonable range.

[0027] The drive motor 2 is a servo motor with a built-in position feedback module, which can dynamically adjust its speed according to the real-time position of the feeding component 6. This choice has many significant advantages. In terms of dynamic response, the speed can be adjusted in advance at critical positions, and the mechanical structure can reduce the impact and vibration of tipping, preventing material deviation. In the face of load changes, it can intelligently compensate for torque, stabilize the tension of the synchronous belt, and prevent transmission loss of synchronization. In terms of energy consumption control, the energy consumption per cycle can be reduced by planning the speed curve and regenerative braking technology. At the same time, the position feedback module can monitor the operating status in real time, quickly respond to anomalies and trigger protection mechanisms, reducing the risk of failure.
