Description

Technical Field

[0001] The present invention belongs to the technical field of semiconductor pressing devices, and more specifically, relates to a pressing device, a carrier unit provided with the pressing device, and a corresponding carrier plate. Background Art

[0002] In an automated production line, if the workpiece to be processed needs to be limited or fixed to ensure that the workpiece maintains the correct position during processing, a limiting structure will inevitably be used to guarantee the processing position of the workpiece.

[0003] In actual design, to limit the degrees of freedom of the movement of the workpiece, methods such as clamping and pressing the workpiece can be adopted. However, when it comes to automated limiting and rapid picking and loading of workpieces, mechanisms must be used to complete these tasks. These mechanisms often adopt linear motion, rotational motion, and linear + rotational compound motion methods to achieve the functions of limiting or fixing the workpiece, opening when picking up the workpiece, and closing after loading the workpiece. And in the case of fragile workpieces, small limiting and fixing devices are mostly used.

[0004] However, in existing solutions, small components that perform reciprocating linear motion or horizontal rotational motion are often used to ensure workpiece limiting, workpiece loading, and workpiece unloading. But such a structure has the following defects: First, the structure is complex, the precision of the mating parts is high, and for such a small device, its parts are not easy to manufacture; second, the consistency is poor, the device is prone to jamming, resulting in a phenomenon where some parts cannot be opened; third, the components are prone to scratching the workpiece, causing cost losses to the workpiece. At the same time, it is difficult for a device using a flipping structure to achieve immediate opening and dropping.

[0005] Therefore, there is an urgent need to design a pressing device that can overcome the above defects. Summary of the Invention

[0036] In order to more clearly understand the above objects, features and advantages of the present invention, the embodiments of the present invention will be further described below. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0037] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0038] As Figures 1-5 shown, in the embodiment of the present invention, a tablet pressing device 8 is provided, including: a rotating element 2, a pressing needle assembly 4, an elastic element 3, a magnetic element 6, a pressing element 5 and a connecting element 7. The pressing needle assembly 4 is fixedly connected to the rotating element 2, and a needle tip 9 is provided on the pressing needle assembly 4, and the needle tip 9 is used for limiting or fixing the workpiece; the elastic element 3 is connected to the pressing needle assembly 4 and drives the pressing needle assembly 4 to open and reset; the magnetic element 6 is fixedly connected to the pressing needle assembly 4 and flips and opens the pressing needle assembly 4 in response to an external force; the pressing element 5 is fixedly connected to the rotating element 2 and presses the rotating element 2; the connecting element 7 fixedly connects the magnetic element 6 and the pressing needle assembly 4.

[0039] The tablet pressing device of the present invention has a compact overall structure, with a maximum range not exceeding 30 mm, and mostly uses standard parts, reducing the design cost. The linear force of the elastic element of the present invention has been playing a role in the tablet pressing device, not only ensuring the reset pre-tightening state of the pressing needle assembly, but also accurately limiting the angle when the pressing needle assembly flips, and providing a stable downward acting force when the pressing needle assembly falls or resets, thus effectively ensuring the reliable and stable fall of the tablet pressing device. The present invention also uses the principle of repulsion between like poles of magnets to apply an external force to the tablet pressing device, and this method is not easily failed and has high reliability. The tablet pressing device of the present invention can effectively limit or fix the workpiece and prevent the workpiece from falling during the flipping process; the tablet pressing device of the present invention can be opened and dropped immediately, meeting the production rhythm, with a simple structure, a long service life and cost savings.

[0040] In the structure shown in the above embodiment of the present invention, as Figure 3As shown, the rotating element 2 is preferably, for example, a cylindrical pin, and the pressing element 5 is preferably, for example, a flat head screw. Thus, the body of the cylindrical pin is fixedly connected to the pressing needle assembly 4, and both ends of the cylindrical pin are respectively fixedly connected to the flat head screws and are pressed by the flat head screws. The cylindrical pin acts as a rotating shaft, facilitating the opening and falling (resetting) of the pressing needle assembly 4 as the cylindrical pin rotates. The flat head screws can press the rotating element 2, that is, press the cylindrical pin, thereby ensuring the trajectory when the entire tablet pressing device 8 flips. Of course, in alternative embodiments, the rotating element 2 and the pressing element 5 can both adopt other similar related components.

[0041] In the structure shown in the above embodiment of the present invention, as Figures 4-5 shown, the magnetic element 6 is preferably, for example, a high-temperature magnet, and the connecting element 7 is preferably, for example, a hollow rivet. The magnetic element 6 is a high-temperature magnet and is fixedly connected to the pressing needle assembly 4 through the connecting element 7. Its function is to receive the applied external force and achieve the flipping of the pressing needle assembly 4, that is, the open state. Of course, in alternative embodiments, the magnetic element 6 and the connecting element 7 can adopt other similar related components.

[0042] In the structure shown in the above embodiment of the present invention, as Figure 3 shown, the elastic element 3 is preferably, for example, a torsion spring. The angle of this torsion spring is 165 - 170° in the initial state before installation and 180° in the installed state after installation. The torsion spring provides a preload of 10 - 15° after installation, ensuring that the pressing needle assembly 4 reliably limits the position of the workpiece at any angle without applying other external forces. The elastic element 3 being a torsion spring ensures that the pressing needle assembly 4 can be quickly opened and fall when loading and unloading the workpiece. Of course, in alternative embodiments, the elastic element 3 can adopt other similar related components.

[0043] In the structure shown in the above embodiment of the present invention, as Figure 5 shown, the opening and closing angle of the pressing needle assembly 4 relative to the axis of the rotating element 2 (cylindrical pin) is 0 - 90°, and the workpiece is grabbed when the opening and closing angle is above 60°. Additionally, the external force can be applied through an external permanent magnet or electromagnet to repel the magnetic element 6 and cause the pressing needle assembly 4 to flip upward and open. When an external magnetic force is applied, based on the principle of repulsion of the magnetic element 6, a force for flipping the pressing needle assembly 4 upward and opening is provided. The elastic element 3 (torsion spring) can accurately ensure the flipping angle of the pressing needle assembly 4. At the same time, when the external force is withdrawn, the elastic element 3 will apply a force perpendicular to the pressing needle assembly 4 downward, causing the pressing needle assembly 4 to quickly fall or reset.

[0044] In the structure shown in the above embodiment of the present invention, as Figure 3 and 5As shown, the diameter of the needle 9 is preferably 0.1 mm. The structural design of the 0.1 mm fine needle 9 at the front end of the needle pressing assembly 4 ensures that the workpiece processing is not blocked.

[0045] In addition, an embodiment of the present invention further provides a carrier plate unit 1, as Figures 1-3 shown, the carrier plate unit 1 includes the above-mentioned pressing device 8 provided on the carrier plate unit 1, wherein the rotating element 2 of the pressing device 8 is fixed on the carrier plate unit 1.

[0046] Furthermore, an embodiment of the present invention also provides a carrier plate, which includes a plurality of the above-mentioned carrier plate units 1 arranged adjacent to each other.

[0047] In the structure shown in the above embodiment of the present invention, as Figure 1 shown, each carrier plate unit 1 is provided with a pressing device 8 with the needle facing inside the carrier plate unit and a pressing device 8 with the needle facing outside the carrier plate unit. Among them, the pressing device 8 with the needle facing inside the carrier plate unit positions or fixes the workpiece on the carrier plate unit 1, and the pressing device 8 with the needle facing outside the carrier plate unit faces the adjacent carrier plate unit and positions or fixes the workpiece on the adjacent carrier plate unit. In this structural design, the number of the pressing devices 8 with the needle facing inside the carrier plate unit can be 6 - 8, and the number of the pressing devices 8 with the needle facing outside the carrier plate unit can also be 6 - 8. The number of the pressing devices 8 with the needle facing inside the carrier plate unit and the number of the pressing devices 8 with the needle facing outside the carrier plate unit can be equal or unequal.

[0048] In the structure shown in the above embodiment of the present invention, the carrier plate can be composed of dozens of the above-mentioned carrier plate units 1, and the carrier plate is designed with mounting grooves and avoidance grooves with different depths.

[0049] The above technical solutions of the present invention will be described in detail below through the description of specific embodiments.

[0050] Again, as Figure 1 shown, Figure 1 shows a schematic structural diagram of a carrier plate unit provided in an embodiment of the present invention. Twelve pressing devices 8 are provided on the carrier plate unit 1, and six of the pressing devices 8 with the needle facing inside the carrier plate unit position or fix the workpiece on the carrier plate unit 1, and the remaining six pressing devices 8 with the needle facing outside the carrier plate unit face the adjacent carrier plate unit and position or fix the workpiece on the adjacent carrier plate unit.

[0051] As Figure 2 shown, Figure 2 shows Figure 1 a side view structural diagram. In this structural diagram, a structure in which a part of the pressing device 8 is turned up 90° to open is shown.

[0052] AsFigures 3-5 As shown, a tablet pressing device 8 provided in this embodiment is shown in detail. The tablet pressing device 8 includes: a rotating element 2, a pressing needle assembly 4, an elastic element 3, a magnetic element 6, a pressing element 5, and a connecting element 7. The rotating element 2 uses a cylindrical pin as a rotating shaft and is fixed on the carrier plate unit 1. The pressing element 5 uses a flat head screw. Both ends of the cylindrical pin are fixedly connected to the flat head screw and are pressed by the flat head screw on the carrier plate unit 1. The rear end of the pressing needle assembly 4 is fixedly connected to the main body of the cylindrical pin so as to open and fall (reset) with the rotation of the cylindrical pin. The front end of the pressing needle assembly 4 is provided with a needle head 9, and the needle head 9 is used for limiting or fixing the workpiece. The elastic element 3 is a torsion spring, which is connected to the pressing needle assembly 4 and drives the pressing needle assembly 4 to open and reset. The magnetic element 6 uses a high-temperature magnet. The high-temperature magnet is fixedly connected to the pressing needle assembly 4 through a connecting element 7 (hollow rivet) and causes the pressing needle assembly 4 to flip upward and open in response to an external force (a repulsive force repelling the high-temperature magnet).

[0053] In the above structural design, the angle of the torsion spring is 165 - 170° in the initial state before installation and 180° in the installed state after installation. The torsion spring provides a preload of 10 - 15° after installation, ensuring that the pressing needle assembly 4 can reliably limit the workpiece at any angle without applying other external forces, thereby ensuring that the pressing needle assembly 4 can quickly open and fall when loading and unloading the workpiece.

[0054] In the above structural design, the flat head screw presses the cylindrical pin to ensure the trajectory of the entire tablet pressing device 8 during flipping.

[0055] In the above structural design, the high-temperature magnet is fixedly connected to the pressing needle assembly 4 through a hollow rivet. As Figures 4-5 shown, the high-temperature magnet is fixedly connected below the pressing needle assembly 4 through a hollow rivet. Its function is to receive the applied external force and realize the flipping of the pressing needle assembly 4, that is, the open state. When an external magnetic force is applied, through the principle of repulsion of the high-temperature magnet, a force for flipping the pressing needle assembly 4 upward is provided. The torsion spring can accurately ensure the flipping angle of the pressing needle assembly 4. At the same time, when the external force is withdrawn, the torsion spring applies a force perpendicular to the pressing needle assembly 4 downward, causing the pressing needle assembly 4 to quickly fall or reset. Both the high-temperature magnet and the torsion spring are made of corrosion-resistant and high-temperature-resistant materials to ensure the service life of the tablet pressing device 8.

[0056] In the above structural design, the opening and closing angle of the pressing needle assembly 4 relative to the axis of the cylindrical pin is 0 - 90°. When it is above 60°, the workpiece can be grabbed, and when it is above 90°, it will interfere with the adjacent carrier plate unit. As Figure 5 shown, the pressing needle assembly 4 flips upward 90° to open.

[0057] During the process of fixing and using the tablet pressing device 8 on the carrier plate unit 1, when it is necessary to limit or fix the workpiece, a repulsive force is generated between an external permanent magnet or electromagnet and the high-temperature magnet, pushing the pressing needle assembly 4 connected to the high-temperature magnet to rotate upward with the cylindrical pin and turn over to an appropriate angle. At this time, the workpiece is grasped and placed at an appropriate position, and then the repulsive force is removed. The torsion spring will apply a force perpendicular to the pressing needle assembly 4 downward, causing the pressing needle assembly 4 to quickly fall or reset, so as to ensure that the needle tip 9 of the pressing needle assembly 4 limits or fixes the placed workpiece. Of course, when it is necessary to remove the workpiece that has been limited or fixed, a repulsive force can be generated again between an external permanent magnet or electromagnet and the high-temperature magnet, pushing the pressing needle assembly 4 connected to the high-temperature magnet to turn over upward to an appropriate angle, so as to grasp or remove the corresponding workpiece.

[0058] It can be seen that the tablet pressing device of the present invention can effectively limit or fix the workpiece and prevent the workpiece from falling during the turnover process; the tablet pressing device of the present invention can be opened and dropped immediately, meeting the production rhythm, with a simple structure, a long service life, and cost savings. The tablet pressing device of the present invention can, for example, adopt a high-temperature magnet + pressing needle assembly + torsion spring, and use a permanent magnet or electromagnet to apply an external force to achieve the functions of workpiece loading, workpiece fixing, and workpiece unloading. Therefore, the tablet pressing device of the present invention can be used in production equipment where the workpiece needs to be fixed or limited and unloaded during the processing; the tablet pressing device of the present invention can also be used in production equipment where the workpiece needs to be turned over.

[0059] In addition, the tablet pressing device of the present invention can be used on a photovoltaic automated production line to limit or fix fragile workpieces, ensure that the workpieces do not fall during the turnover process, and at the same time facilitate the loading and unloading of the workpieces. However, the present invention is not limited to being used in photovoltaic automated production equipment, nor is it limited to being used in automated equipment that needs to limit workpieces.
