Description

Technical Field

[0001] This invention belongs to the field of vacuum packaging technology, and particularly relates to a vacuum packaging machine for precision devices. Background Technology

[0002] Vacuum sealing can effectively isolate the external environment and prevent harmful substances such as moisture and dust from entering the packaging, thereby avoiding contamination and damage to precision components.

[0003] Traditional vacuum sealing machines use a carrier tray to transport materials into the vacuum chamber, which provides a vacuum environment for sealing. However, these machines have several drawbacks. Before entering the vacuum chamber, the material is directly exposed to the external environment, allowing dust and dirt to settle and adhere to it. This contamination before processing can negatively impact quality, especially for precision components. Dust can hinder the tight adhesion between the sealing material and the device surface, leading to incomplete sealing or gaps, thus affecting the quality and seal. Furthermore, dust may contain harmful substances or conductive particles that can penetrate the seal and come into contact with sensitive parts of the device, causing performance degradation or failure. Therefore, preventing dust from settling on the material before processing and thus avoiding contamination is a crucial design challenge for vacuum sealing machines. Summary of the Invention

[0004] This invention provides a vacuum sealing machine for precision devices to solve the technical problem of dust easily adhering due to lack of shielding and protection before and after processing, and before material processing.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions:

[0006] This invention provides a vacuum packaging machine for precision devices, comprising a vacuum packaging machine body having a vacuum chamber; further comprising: a translation mechanism extending through an inlet / outlet on one side of the vacuum chamber and extending to a side wall of the vacuum chamber away from the inlet / outlet; a material tray for holding materials, the material tray being detachably mounted on a movable part of the translation mechanism, and an openable / closable shielding mechanism being provided above the material tray; and a pressing and sealing mechanism disposed on the movable part of the translation mechanism, the pressing and sealing mechanism having a pressing and locking mechanism that provides driving force by pressing the side wall of the vacuum chamber, the pressing and locking mechanism being connected to the shielding mechanism via an opening mechanism.

[0007] In this technical solution, a translation mechanism is used for moving and conveying the material tray, facilitating the entry and exit of the material tray into or out of the vacuum chamber, thus simplifying material handling during processing. Furthermore, the detachable installation of the material tray and the inclusion of a compression locking mechanism ensure that the material tray, located outside the vacuum chamber, remains unlocked before and after processing. The tray can be easily removed or placed on the translation mechanism. Driven by the translation mechanism, the tray enters the vacuum chamber, where a compression sealing mechanism seals the inlet and outlet, providing a seal. Simultaneously, the compression action provides driving force, locking the material tray to ensure stability during processing. After processing, the translation mechanism moves the tray out of the vacuum chamber, releasing the compression force and automatically resetting to the unlocked state. Further... A shielding mechanism is incorporated into the first step. Before and after material processing, the shielding mechanism protects the material from dust, making it suitable for processing precision components and preventing dust from settling on the material and affecting its quality. An opening mechanism is also included. During processing, the shielding mechanism opens, releasing it from obstruction and ensuring smooth processing. The opening mechanism is driven by a compression locking mechanism, eliminating the need for an additional power source. After processing, once the material leaves the vacuum chamber and the compression force is released, the shielding mechanism automatically resets to protect the material again. The locking of the material tray during processing, its unlocking before and after processing, and the shielding mechanism's protection of the material before and after processing, as well as its release from obstruction during processing, are all driven by compression against the vacuum chamber wall. The entire system requires only a power source on the translation mechanism, eliminating the need for other power sources.

[0013] In this technical solution, the pressing and sealing mechanism moves together with the material tray driven by the translation mechanism. After the material tray enters the vacuum chamber, the pressing and sealing mechanism seals the inlet and outlet to form a sealed environment. After processing, the material tray leaves the vacuum chamber and the inlet and outlet are opened.

[0014] Preferably, a positioning socket is fixedly connected to the bottom of the material tray, and the positioning socket is connected to a positioning insertion hole opened on the top of the movable block.

[0020] Preferably, a plurality of second helical springs are provided on one side of the connecting strip, one end of the second helical springs is fixedly connected to the connecting strip, and the other end of the second helical springs is fixedly connected to the inner wall of the positioning socket.

[0021] In this technical solution, the second helical spring is used to provide the reset driving force for the blocking mechanism to close.

[0022] Preferably, the shielding mechanism includes two movable covers and a pressing connecting frame. The two movable covers are symmetrically arranged on the top of the material tray.

[0026] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0027] The positive and progressive effects of this invention are as follows:

[0028] The aforementioned vacuum sealing machine for precision devices utilizes a shielding mechanism to protect materials before and after processing, preventing dust from entering. During processing, the shielding is removed to ensure smooth operation. A compression locking mechanism locks the material tray during processing, ensuring its stability, while keeping it unlocked before and after processing for easy loading, unloading, and replacement on the translation mechanism. Furthermore, the shielding mechanism is driven by an opening mechanism connected to the compression locking mechanism. The compression locking mechanism moves through the movable part of the translation mechanism, making close contact with the vacuum chamber wall for propulsion.

[0049] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0050] like Figure 1-10 As shown, a vacuum sealing machine for precision devices includes a vacuum sealing machine body 1, which has a vacuum chamber 101; it also includes: a translation mechanism 3, which passes through an inlet / outlet 1011 on one side of the vacuum chamber 101 and extends to the side wall of the vacuum chamber 101 away from the inlet / outlet 1011; a material tray 4 for holding materials, which is detachably mounted on the movable part of the translation mechanism 3, and an openable / closable shielding mechanism 5 is provided above the material tray 4; and a pressing and sealing mechanism 6, which is provided on the movable part of the translation mechanism 3, and has a pressing and sealing mechanism 7 that provides driving force by pressing the side wall of the vacuum chamber 101, which is connected to the shielding mechanism 5 through an opening mechanism 9.

[0051] In practical implementation, the translation mechanism 3 is used for the movement and conveying of the material tray 4, facilitating the entry and exit of the material tray 4 into or from the vacuum chamber 101, thus simplifying material handling during processing. Furthermore, the detachable installation of the material tray 4 and the setting of the compression locking mechanism 7 ensure that the material tray 4 is located outside the vacuum chamber 101. Before and after processing, the compression locking mechanism 7 does not lock the material tray 4, keeping it in an unlocked state. The material tray 4 can be easily removed or placed on the translation mechanism 3. Driven by the translation mechanism 3, after entering the vacuum chamber 101, the compression sealing mechanism 6 compresses and seals the entrance and exit of the vacuum chamber 101, providing a seal. Simultaneously, during the compression process, the compression action provides driving force, causing the compression locking mechanism 7 to lock the material tray 4, ensuring its stability during processing. After processing, driven by the translation mechanism 3, the material tray 4 leaves the vacuum chamber 101, losing the compression force and automatically returning to its original position. The system is further equipped with a shielding mechanism 5, which shields the material before and after processing, providing protection and dust prevention. This is suitable for processing precision components, preventing dust from falling onto the material and affecting its quality. An opening mechanism 9 is also included. During processing, the shielding mechanism 5 is opened, removing its shielding effect and ensuring the smooth progress of processing. The opening mechanism 9 is driven by the compression locking mechanism 7, eliminating the need for an additional power source. After processing, the shielding mechanism automatically resets after leaving the vacuum chamber 101, losing its compressive force and re-shielding the material. The locking of the material tray 4 during processing, its unlocking before and after processing, and the shielding mechanism 5's shielding before and after processing, as well as its removal of shielding during processing, are all driven by compression against the wall of the vacuum chamber 101. The entire system requires only a power source on the translation mechanism 3, eliminating the need for other power sources.

[0052] like Figure 2 As shown, as a specific technical solution, the vacuum sealing machine body 1 is equipped with a vacuum pump 102, which is connected to the vacuum chamber 101 through a vacuum tube 103.

[0053] The vacuum pump 102 can evacuate the vacuum tube 103 through the vacuum tube 103, providing a vacuum processing environment for the vacuum sealing machine body 1.

[0054] like Figure 1As shown, as a specific technical solution, the translation mechanism 3 includes a fixed end plate 301, a screw 302, a servo motor 303, a guide rod 304, and a movable block 305; a support frame 2 is fixedly connected to the bottom of the fixed end plate 301, the servo motor 303 is fixedly installed on one side wall of the fixed end plate 301, and the output shaft end of the servo motor 303 is fixedly connected to one end of the screw 302, the side wall of the fixed end plate 301 is fixedly connected to one end of the guide rod 304, and the guide rod 304... Both the guide rod 304 and the screw 302 pass through the inlet and outlet 1011 of the vacuum chamber 101. One end of the guide rod 304 is fixedly connected to the inner wall of the vacuum chamber 101 away from the inlet and outlet 1011. One end of the screw 302 is rotatably connected to the inner wall of the vacuum chamber 101 away from the inlet and outlet 1011. The movable block 305 is provided with a guide hole 3052 and a screw hole 3053. The guide hole 3052 is clearance-fitted with the guide rod 304, and the screw hole 3053 is threadedly connected to the screw 302.

[0055] The servo motor 303 drives the screw 302 to rotate, and the screw 302 is screwed into the screw hole 3053. With the guidance of the guide hole 3052 and the guide rod 304, the movable block 305 can be translated and moved, so that the movable block 305 and the structure on the movable block 305 can enter or leave the vacuum chamber 101.

[0056] like Figure 3 and 4 As shown, as a specific technical solution, the pressing and sealing mechanism 6 includes a first fixing tube 601, a pressure plate 602, a second sealing ring 603, a second fixing tube 604, and a third sealing ring 605. The first fixing tube 601 and the second fixing tube 604 are both fixedly connected to the movable block 305, and there are two of each. The two first fixing tubes 601 are respectively connected to both ends of the screw hole 3053, and the two second fixing tubes 604 are respectively connected to both ends of the guide hole 3052. The screw 302 and the guide rod 304 pass through the first fixing tube 601 and the second fixing tube 604 respectively. The ends of the first fixing tube 601 and the second fixing tube 604 on one side of the movable block 305 are fixedly connected to the third sealing ring 605. The ends of the first fixing tube 601 and the second fixing tube 604 on the other side of the movable block 305 are fixedly sleeved with the pressure plate 602, and the edge of the pressure plate 602 is fixedly connected to the second sealing ring 603.

[0057] When the movable block 305 moves, the pressing and sealing mechanism 6 moves along with it. During the process of the movable block 305 moving into the vacuum chamber 101, the first fixed tube 601 and the second fixed tube 604 on one side of the movable block 305 enter the vacuum chamber 101 together with the movable block 305 until the third sealing ring 605 on it is pressed against the inner wall of the vacuum chamber 101 away from the inlet and outlet 1011. At the same time, the pressure plate 602 covers the inlet and outlet 1011, and the second sealing ring 603 is pressed against the outer wall around the inlet and outlet 1011 of the vacuum chamber 101. After the above pressing, the inlet and outlet 1011 is blocked, so that the vacuum chamber 101 forms a sealed environment. When the movable block 305 leaves the vacuum chamber 101, the pressing and sealing mechanism 6 moves along with it, and the blocking of the inlet and outlet 1011 is removed. Through the above design, after the material enters the vacuum chamber 101 with the movable block 305, the vacuum chamber 101 forms a sealed environment. When the material leaves the vacuum chamber 101 with the movable block 305, the inlet and outlet 1011 are opened.

[0058] like Figure 4 and 6 As shown, as a specific technical solution, a positioning socket 8 is fixedly connected to the bottom of the material tray 4, and the positioning socket 8 is connected to the positioning insertion hole 3051 opened on the top of the movable block 305. A connecting hole 3054 communicating with the positioning insertion hole 3051 is opened on one side of the movable block 305. The compression locking mechanism 7 includes a fixed guide seat 701, a movable rod 702, and an insertion rod 703 fixedly connected to the first fixed tube 601. A guide groove 704 is opened at one end of the fixed guide seat 701. The other end of 1 has an installation hole. The movable rod 702 passes through the guide groove 704 and the installation hole, and the movable rod 702 is connected to the guide groove 704 with a clearance fit. A first helical spring 705 is provided in the installation hole. The movable rod 702 is elastically connected to the fixed guide seat 701 through the first helical spring 705. The insertion rod 703 is fixedly connected to one end of the movable rod 702, and the insertion rod 703 is connected to the connecting hole 3054 with a clearance fit. The positioning socket 8 is provided with a locking sleeve 801 that is adapted to the insertion rod 703.

[0059] The material tray 4 is inserted into the positioning socket 3051 through the positioning socket 8 for positioning. Before and after processing, the pressing locking mechanism 7 does not lock the positioning socket 8 and is in the unlocked state. The material tray 4 can be easily picked up and put on the movable block 305 for easy replacement. To change materials, the material tray 4 carrying the processed material is taken out and replaced with the material tray 4 carrying the unprocessed material.

[0060] As the movable block 305 enters the vacuum chamber 101, the material tray 4 moves along with it and enters the vacuum chamber 101. The sealing mechanism 6 seals the inlet and outlet, forming a seal. At the same time, the compression locking mechanism 7 moves together. The end of the movable rod 702 of the compression locking mechanism 7 presses against the inner wall of the vacuum chamber 101. The movable rod 702 moves about the fixed guide seat 701, and at the same time stretches the first helical spring 705, generating a restoring elastic force. When the movable rod 702 moves, the insertion rod 703 moves along with it and inserts into the locking sleeve 801 of the positioning socket 8 to lock it, limiting and locking the material tray 4, ensuring the stability of the material tray 4 during processing.

[0061] After processing, the movable block 305 leaves the vacuum chamber 101, and the movable rod 702 separates from the inner wall of the vacuum chamber 101. The movable rod 702 and the insertion rod 703 are driven to move back to their original positions by the reset force of the first helical spring 705. The insertion rod 703 is pulled out of the locking sleeve 801, and the locking is canceled. The locking and unlocking in the above process can be performed automatically, and the extrusion pressure is released.

[0062] like Figure 7 As shown, as a specific technical solution, the opening mechanism 9 includes a transmission assembly, a second cylindrical gear 914, and two second racks 915. The transmission assembly is disposed inside the positioning socket 8, and a connecting strip 903 is fixedly connected to the input end of the transmission assembly. A movable column 901 is fixedly connected to the connecting strip 903. The movable column 901 extends into the interior of the locking sleeve 801, and an end plate 902 is fixedly connected to one end of the movable column 901. The output end of the transmission assembly is connected to the second cylindrical gear 914. The two second racks 915 are respectively meshed with the front and rear sides of the second cylindrical gear 914, and each of the two second racks 915 is fixedly connected to a connecting rod 916. The transmission assembly includes a first rack 904, a first rotating shaft 907, a second rotating shaft 909, and a third rotating shaft 913 fixedly connected to the connecting strip 903. The first rotating shaft 907 and the second rotating shaft 909 are... Both 09 and the third rotating shaft 913 are rotatably installed inside the positioning socket 8. A first cylindrical gear 905 and a first bevel gear 906 are fixedly sleeved on the first rotating shaft 907. The first cylindrical gear 905 is meshed with the first rack 904. A second bevel gear 910 and a third bevel gear 911 are fixedly sleeved on the second rotating shaft 909. The third bevel gear 911 is meshed with the first bevel gear 906. The second bevel gear 910 is meshed with the fourth bevel gear 912 fixed to the bottom end of the third rotating shaft 913. The second cylindrical gear 914 is fixedly sleeved on the third rotating shaft 913. A plurality of second helical springs 908 are provided on one side of the connecting strip 903. One end of the second helical spring 908 is fixedly connected to the connecting strip 903, and the other end of the second helical spring 908 is fixedly connected to the inner wall of the positioning socket 8.

[0063] The opening mechanism 9 is used to open the blocking mechanism 5 and remove the material blocking. The specific process is as follows: the insert rod 703 is inserted into the locking sleeve 801 to press the end plate 902 and the movable column 901. The movable column 901 drives the connecting strip 903 and the first rack 904 to move together, while compressing the second helical spring 908. During the movement of the first rack 904, the first cylindrical gear 905 is driven to rotate through meshing transmission, so that the first rotating shaft 907, the first cylindrical gear 905 and the first bevel gear 906 move together. The shaft rotates, and through the meshing transmission of the first bevel gear 906 and the third bevel gear 911, the second shaft 909 rotates. Through the meshing transmission of the second bevel gear 910 and the fourth bevel gear 912, the third shaft 913 rotates. The second cylindrical gear 914 rotates together with the third shaft 913. Through the meshing transmission of the second cylindrical gear 914 and the second rack 915, the two second racks 915 drive the connecting rod 916 to move. The movement of the connecting rod 916 drives the blocking mechanism 5 to open.

[0064] During the process of the insertion rod 703 being pulled out of the locking sleeve 801, the elastic force of the second helical spring 908 drives the connecting bar 903, the movable rod 702 and the first rack 904 to reset. Through the above transmission process, the connecting rod 916 is reset, and the connecting rod 916 drives the blocking mechanism 5 to close.

[0065] The opening mechanism 9 described above is driven by the compression locking mechanism 7.

[0066] like Figure 5 , Figure 8 As shown in Figure 10, as a specific technical solution, the shielding mechanism 5 includes two movable covers 501 and a pressing connecting frame 503. The two movable covers 501 are symmetrically arranged on the top of the material tray 4. One side and the bottom of each movable cover 501 are open. A first sealing ring 502 is fixedly connected to the edge of the opening of each movable cover 501. Both movable covers 501 are connected to the connecting rod 916 through the pressing connecting frame 503. The pressing connecting frame 503 includes a first frame 5031, a second frame 5032, and a gas spring 5033. The gas spring 5033 is installed inside the second frame 5032, and the second frame 5032 is elastically connected to the first frame 5031 through the gas spring 5033. The second frame 5032 is fixedly connected to one end of the connecting rod 916, and the first frame 5031 is fixedly connected to the outer wall of the movable cover 501.

[0067] The shielding mechanism 5 opens by moving the two movable covers 501 away from each other via the connecting rod 916. The shielding mechanism 5 closes by moving the two movable covers 501 closer together via the connecting rod 916. At the same time, the first sealing ring 502 provides a seal when closed. In the closed state, the second helical spring 908 has a certain compression force, which presses the two movable covers 501 together. The gas spring 5033 has elastic pulling force, which presses the bottom of the movable cover 501 against the top surface of the material tray 4.
