Description

Technical Field

[0001] The present application relates to the technical field of automated PCB processing, and in particular to a temporary storage device and a control method thereof. Background Art

[0002] The main function of the temporary storage machine is to temporarily store PCB boards in the SMT production line, thereby acting as a buffer, helping to alleviate the speed mismatch problem between different processes, avoiding stagnation and waste of the production line, and thus ensuring the stable and efficient operation of the production line.

[0003] In the actual production process, the PCB boards processed in the previous process are sequentially sent to the temporary storage machine for storage. After the storage is completed, the PCB boards stored in the temporary storage machine are sequentially sent out to the next process. Since the temporary storage machine usually uses a fixedly connected power source, the order of sending in and out the PCB boards is usually first in, last out. However, when there are some special circumstances, it may be necessary to change the order in which the PCB boards are sent out. For example, when a chemical reaction is involved, the PCB board that was first sent to the temporary storage machine for storage needs to be sent out first for the next process to avoid excessive reaction of the PCB board and affect the quality of the finished product. In addition, some emergencies may require that one of the PCB boards be selected to proceed to the next process first. However, the temporary storage machine of the prior art can only maintain the first in, last out order and cannot cope with the above special circumstances. It can only be adjusted manually, resulting in poor flexibility of the temporary storage machine, which leads to low efficiency in PCB board processing. Summary of the Invention

[0004] The purpose of this application is to provide a temporary storage device and a control method thereof, which can improve the flexibility of the temporary storage machine and the processing efficiency of PCB boards.

[0005] In the first aspect, the present application provides a temporary storage device that adopts the following technical solution:

[0006] A temporary storage device includes a protective cover, a controller installed outside the protective cover, a frame installed inside the protective cover, and a storage mechanism, a driving mechanism, and a lifting mechanism installed on the frame, wherein the driving mechanism and the lifting mechanism are in communication with the controller;

[0007] The storage mechanism includes a lifting platform, a fixing frame mounted on the lifting platform, and a plurality of storage components placed on the fixing frame. The lifting mechanism is connected to the lifting platform and is used to drive the storage mechanism to move in a vertical direction.

[0008] A drive shaft is provided on one side of each storage assembly, and the drive shaft is used to connect to the drive mechanism through a magnetic coupling when the position of the storage assembly that needs to be loaded or unloaded is flush with the drive mechanism;

[0009] The driving mechanism is used to move away from the storage component when the lifting mechanism drives the storage mechanism to move in the vertical direction, and when the position of the storage component that needs to be loaded or unloaded is flush with the driving mechanism, move close to the storage component and drive the storage component to load or unload through the magnetic coupling.

[0010] By adopting the above technical solution, the present application connects the drive mechanism and the storage mechanism through a magnetic coupling. When a storage component needs to be loaded or unloaded, it is only necessary to move the storage component to a position flush with the drive mechanism through the lifting mechanism, and then connect it through the magnetic coupling so that the drive mechanism can drive the storage component to load or unload. Because the magnetic connection is not a fixed connection, the required storage components can be selected in any order for loading or unloading without manual adjustment, thereby improving the flexibility of the temporary storage device and the processing efficiency of the PCB board.

[0011] Furthermore, the storage assembly includes several transmission rollers, one of which serves as a driving roller, and the driving shaft is arranged on the side of the driving roller close to the driving mechanism. The driving shaft is connected to the driving mechanism through a magnetic coupling, and the driving shaft is used to drive the transmission roller to rotate under the drive of the driving mechanism.

[0012] By adopting the above technical solution, the present application controls the driving roller through the driving mechanism to drive several rotating rollers to rotate, so that the PCB boards processed in the previous process are driven by the rotation of the rollers to be sent into the storage component for storage in sequence, or after the storage is completed, the PCB boards stored in the storage component are sent out to the next process in sequence, so that different storage components can be freely selected for loading or unloading without having to follow a specific order, thereby improving the flexibility of the temporary storage device.

[0013] Furthermore, the storage assembly is also provided with a plurality of first pulley groups, and the sides of two adjacent transmission rollers away from the driving mechanism are connected through the first pulley group, and the first pulley group is used to drive all transmission rollers to rotate.

[0014] By adopting the above technical solution, the present application connects several transmission rollers through a pulley group, so that when the driving roller rotates under the drive of the driving mechanism, it can drive the transmission roller to rotate together, ensuring that the PCB board can be stably loaded or unloaded.

[0015] Furthermore, the fixing frame is provided with a plurality of fixing slots at fixed intervals perpendicular to the connection direction of the driving mechanism, and the plurality of storage components are respectively placed on the plurality of fixing slots.

[0016] By adopting the above technical solution, the storage component of the present application is fixed by being placed on the fixing groove, which facilitates the disassembly and replacement of the storage component.

[0017] Furthermore, the plurality of storage assemblies are provided with snap-fit ​​buckles at both ends of the plurality of first pulley groups, and the snap-fit ​​buckles are used to snap-fit ​​with the fixing frame to fix the storage assemblies on the fixing frame;

[0018] A plurality of pulleys are provided on both sides of the plurality of storage components in contact with the fixed groove, and the pulleys are used to make the storage components in sliding contact with the fixed groove.

[0019] By adopting the above technical solution, the present application fixes the storage component to the fixed frame through a snap buckle, and makes the storage component contact with the fixed slot through a pulley, so that when a PCB board needs to be used urgently, the snap buckle of the corresponding storage component can be loosened, and the storage component can be smoothly pulled out of the fixed frame through the pulley, which is convenient for dealing with emergencies and improving the flexibility of the temporary storage device.

[0020] Furthermore, the driving mechanism includes a driving component and a moving component, the driving component is mounted on the moving component, and the moving component is used to drive the driving component to move toward or away from the storage mechanism.

[0021] By adopting the above-mentioned technical solution, the present application drives the driving component to move toward or away from the storage mechanism through the moving component, and moves away from the storage mechanism when the storage mechanism is raised or lowered to avoid hindering the raising or lowering. When the storage mechanism is raised or lowered to the required position, the driving component moves close to the storage mechanism so that the driving component can drive the corresponding storage component, thereby ensuring the stability of the operation of the temporary storage device.

[0022] Furthermore, the drive assembly includes a drive motor, and the output shaft of the drive motor is connected to the drive shaft of the storage assembly through a magnetic coupling;

[0023] The moving assembly includes a cylinder, a slider and a slide rail. The cylinder output shaft is connected to the slider. The drive motor is installed on the slider. The slider is slidably connected to the slide rail.

[0024] By adopting the above technical solution, the present application realizes the movement of the driving mechanism toward or away from the storage mechanism through the cylinder, slide rail and slider, and drives the storage assembly to rotate through the driving motor, thereby realizing loading or unloading and ensuring the stability of the storage device.

[0025] Furthermore, the lifting mechanism includes a power assembly and a transmission assembly, and the power assembly is used to drive the transmission assembly to move the lifting mechanism in a vertical direction;

[0026] The power assembly includes a lifting motor, a first screw rod, a second pulley set and a first lifting block. The output shaft of the lifting motor is connected to the top of the first screw rod through the second pulley set. The first lifting block is fixedly connected to the lifting platform and threadedly connected to the first screw rod.

[0027] By adopting the above technical solution, this application realizes the lifting and lowering of the storage mechanism through the cooperation of the power component and the transmission component, drives the lifting motor, and converts the rotation of the motor output shaft into up and down movement through the threaded connection between the screw rod and the lifting block, thereby ensuring the stability of the lifting and lowering of the storage device.

[0028] Furthermore, the transmission assembly includes a third pulley group, a second screw rod and a second lifting block, the bottom of the second screw rod is connected to the bottom of the first screw rod through the third pulley group, and the second lifting block is fixedly connected to the lifting platform and threadedly connected to the second screw rod.

[0029] By adopting the above technical solution, the present application connects the first screw rod and the second screw rod through a belt group so that the second screw rod can rotate synchronously with the first screw rod, and the rotation is converted into up and down movement through the threaded connection between the screw rod and the lifting block, thereby ensuring the stability of the lifting of the storage device.

[0030] In a second aspect, the present application provides a temporary storage device control method using the following technical solutions:

[0031] A temporary storage device control method, applied to the temporary storage device described in the first aspect, comprising:

[0032] When a storage component needs to load or unload materials, the controller controls the driving mechanism to move away from the storage mechanism;

[0033] The controller controls the lifting mechanism to drive the storage mechanism to move in the vertical direction until the storage assembly is flush with the driving mechanism;

[0034] When the storage assembly is flush with the drive mechanism, the controller controls the drive mechanism to approach the storage assembly and connect with the storage assembly through a magnetic coupling;

[0035] The controller controls the driving component to drive the storage component to load or unload materials.

[0036] By adopting the above-mentioned technical solution, the present application realizes stable loading and unloading of the temporary storage device through the coordinated control of the lifting mechanism and the driving mechanism. The required storage components can be selected in any order for loading or unloading through magnetic connection without manual adjustment, thereby improving the flexibility of the temporary storage device and the processing efficiency of the PCB board.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. This application connects the drive mechanism and the storage mechanism through a magnetic coupling. When a storage component needs to be loaded or unloaded, the storage component only needs to be moved to a position flush with the drive mechanism via the lifting mechanism. Then, the magnetic coupling is connected so that the drive mechanism can drive the storage component to load or unload. Because the magnetic connection is not a fixed connection, the required storage components can be selected in any order for loading or unloading without manual adjustment, thereby improving the flexibility of the temporary storage device and the processing efficiency of PCB boards.

[0039] 2. This application uses a drive mechanism to control a driving roller to drive a plurality of rotating rollers to rotate. PCB boards processed in the previous process are sequentially fed into a storage assembly for storage through the rotation of the rollers. Alternatively, after storage is completed, the PCB boards stored in the storage assembly are sequentially fed out to the next process. This allows for free selection of different storage assemblies for loading or unloading, eliminating the need for a specific order, thereby improving the flexibility of the temporary storage device.

[0040] 3. This application fixes the storage component to the fixing frame through a snap buckle, and makes the storage component contact with the fixing slot through a pulley, so that when a PCB board needs to be used urgently, the snap buckle of the corresponding storage component can be loosened, and the storage component can be smoothly pulled out of the fixing frame through the pulley, which is convenient for dealing with emergencies and improving the flexibility of the temporary storage device.

DETAILED DESCRIPTION

[0048] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0049] In the actual production process, the PCB boards processed in the previous process are sequentially sent to the temporary storage machine for storage, and after the storage is completed, the PCB boards stored in the temporary storage machine are sequentially sent out to the next process. Since the temporary storage machine usually uses a fixedly connected power source, the order of sending in and sending out PCB boards is usually first in, last out. However, when there are some special circumstances, it may be necessary to change the order in which the PCB boards are sent out. For example, when a chemical reaction is involved, the PCB board that was first sent to the temporary storage machine for storage needs to be sent out first for the next process to avoid excessive reaction of the PCB board and affect the quality of the finished product, and some emergencies may require one of the PCB boards to be selected for the next process first. However, the temporary storage machine of the prior art can only maintain the first in, last out order, and cannot cope with the above special circumstances. It can only be adjusted manually, resulting in poor flexibility of the temporary storage machine, which leads to low efficiency in PCB board processing. Therefore, the embodiment of the present application provides a temporary storage device and a control method thereof, with reference to Figure 1 and Figure 2, comprising a protective cover 1, a controller 3 mounted outside the protective cover 1, and a frame 2 mounted inside the protective cover 1, as well as a storage mechanism 4, a driving mechanism 5, a lifting mechanism 6, and a feeding mechanism 7 mounted on the frame 2. The driving mechanism 5, the lifting mechanism 6, and the feeding mechanism 7 are communicatively connected to the controller 3. The driving mechanism 5 is used to drive the storage mechanism 4 to load or unload materials, the lifting mechanism 6 is used to drive the storage mechanism 4 to move in the vertical direction, and the feeding mechanism 7 is used to assist in loading or unloading materials. The storage mechanism 4 comprises a lifting platform 41, a fixed frame 42 mounted on the lifting platform 41, and a plurality of storage components 43 placed on the fixed frame 42. The lifting mechanism 6 is connected to the lifting platform 41. A drive shaft 431 is provided on one side of each storage component 43. The drive shaft 431 is used to connect to the drive mechanism 5 through a magnetic coupling 511 when the position of the storage component 43 to be loaded or unloaded is flush with the driving mechanism 5. During the specific implementation process, when the lifting mechanism 6 drives the storage mechanism 4 to move in the vertical direction, the driving mechanism 5 moves away from the storage component 43. When the position of the storage component 43 that needs to be loaded or unloaded is flush with the driving mechanism 5, the driving mechanism 5 approaches the storage component 43 and drives the storage component 43 to load or unload through the magnetic coupling 511.

[0050] The operating principle of the embodiment of the present application is as follows: the drive mechanism 5 and the storage mechanism 4 are connected via a magnetic coupling 511. When a storage assembly 43 needs to be loaded or unloaded, the lifting mechanism 6 simply moves the storage assembly 43 to a position flush with the drive mechanism 5. The magnetic coupling 511 is then used to connect the storage assembly 43, allowing the drive mechanism 5 to drive the storage assembly 43 for loading or unloading. Because the magnetic connection is not a fixed connection, the desired storage assembly 43 can be selected for loading or unloading in any order without manual adjustment, thereby improving the flexibility of the temporary storage device and the processing efficiency of PCB boards.

[0051] like Figure 2 and Figure 3As shown, the storage assembly 43 of the present embodiment includes several transmission rollers 432, one of which serves as a drive roller 433. A drive shaft 431 is located on the side of the drive roller 433 closest to the drive mechanism 5. The drive shaft 431 is connected to the drive mechanism 5 via a magnetic coupling 511. The drive shaft 431 is used to drive the transmission roller 432 to rotate under the drive mechanism 5. The storage assembly 43 also includes several first pulley sets 434. Two adjacent transmission rollers 432 are connected by the first pulley set 434 on the side away from the drive mechanism 5. The first pulley set 434 is used to drive all transmission rollers 432 to rotate. In a specific embodiment, when the drive shaft 431 of a storage assembly 43 is connected to the drive mechanism 5, the drive roller 433 rotates under the drive mechanism 5, and the other transmission rollers 432 are driven to rotate synchronously through the first pulley set 434. To ensure more uniform force, the drive roller 433 is typically one of the transmission rollers 432 located near the center.

[0052] like Figure 2 As shown, the feed mechanism 7 of the present embodiment includes feed assemblies located at both ends of the drive mechanism 5, meaning that the storage device can load or unload materials from both directions. The feed assemblies are flush with the drive mechanism 5, meaning that the storage assembly 43 needs to be moved to this position for loading or unloading. The feed assembly includes a feed motor 71 and a feed roller 72. The feed motor 71 drives the feed roller 72 to rotate in the same direction as the drive roller 432, thereby assisting the drive roller 432 in loading or unloading.

[0053] like Figure 2 and Figure 3 As shown, the fixed frame 42 of the embodiment of the present application is provided with a plurality of fixed grooves 421 at fixed intervals perpendicular to the connection direction of the drive mechanism 5, and a plurality of storage components 43 are respectively placed on the plurality of fixed grooves 421. The storage component 43 is provided with snap-fit ​​buckles 435 at both ends of the plurality of first pulley sets 434. The snap-fit ​​buckles 435 are used to snap-fit ​​with the fixed frame 42 to fix the storage component 43 on the fixed frame 42. A plurality of pulleys 436 are provided on both sides of the storage component 43 in contact with the fixed groove 421. The pulleys 436 are used to make the storage component 43 slide in contact with the fixed groove 421. In the specific implementation process, when placing the storage component 43 on the fixed frame 42, the storage component 43 is inserted along the corresponding fixed groove 421, and then the snap-fit ​​buckles 435 are snap-fitted to both sides of the fixed frame 42, so that the storage component 43 can be detachably mounted on the fixed frame 42. When a storage component 43 needs to be manually removed, the corresponding snap-on buckle 435 is released, and then the storage component 43 is pulled out from the fixed slot 421. The pulley 436 reduces the friction between the storage component 43 and the fixed slot 421, so that the storage component 43 can be smoothly inserted into or pulled out of the fixed slot 421.

[0054] like Figure 4 As shown, the driving mechanism 5 of the embodiment of the present application includes a driving assembly 51 and a moving assembly 52. ​​The driving assembly 51 is mounted on the moving assembly 52, and the moving assembly 52 is used to drive the driving assembly 51 to move toward or away from the storage mechanism 4. In a specific implementation, when the storage mechanism 4 is raised or lowered, the driving assembly 51 is driven by the moving assembly 52 to move away from the storage mechanism 4 to avoid obstructing the raising or lowering. When the storage mechanism 4 is raised or lowered to the desired position, the driving assembly 51 is driven by the moving assembly 52 to move toward the storage mechanism 4 so that the driving assembly 51 can drive the corresponding storage assembly 43, thereby ensuring the stability of the temporary storage device.

[0055] like Figure 4 As shown, the driving assembly 51 of the embodiment of the present application includes a driving motor 512, and the output shaft of the driving motor 512 is connected to the driving shaft 431 of the storage assembly 43 through a magnetic coupling 511. The moving assembly 52 includes a cylinder 521, a slider 522 and a slide rail 523. The output shaft of the cylinder 521 is connected to the slider 522, and the driving motor 512 is installed on the slider 522. The slider 522 is slidably connected to the slide rail 523. In the specific implementation process, the driving mechanism 5 is moved toward or away from the storage mechanism 4 by the cylinder 521, the slide rail 523 and the slider 522, and the storage assembly 43 is driven to rotate by the driving motor 512.

[0056] like Figure 5 As shown, the lifting mechanism 6 of the embodiment of the present application includes a power assembly 61 and a transmission assembly 62. The power assembly 61 is used to drive the transmission assembly 62 to move the lifting mechanism 6 in the vertical direction. The power assembly 61 includes a lifting motor 611, a first screw rod 612, a second pulley set 613 and a first lifting block 614. The output shaft of the lifting motor 611 is connected to the top of the first screw rod 612 through the second pulley set 613. The first lifting block 614 is fixedly connected to the lifting platform 41 and is threadedly connected to the first screw rod 612. The transmission assembly 62 includes a third pulley set 621, a second screw rod 622 and a second lifting block. The bottom of the second screw rod 622 is connected to the bottom of the first screw rod 612 through the third pulley set 621. The second lifting block is fixedly connected to the lifting platform 41 and is threadedly connected to the second screw rod 622. During implementation, the output shaft of the lifting motor 611 rotates, driving the first screw rod 612 to rotate via the second pulley assembly 613. The rotation of the motor output shaft is converted into vertical movement by the threaded connection between the first screw rod 612 and the first lifting block 614. The first screw rod 612 and the second screw rod 622 are connected by a third belt assembly to enable the second screw rod 622 to rotate synchronously with the first screw rod 612. The rotation is converted into vertical movement by the threaded connection between the second screw rod 622 and the second lifting block.

[0057] In a preferred embodiment, in order to further ensure the stability of the storage mechanism 4 during lifting and lowering, the transmission assembly 62 also includes four sliding rods 623 installed at the four corners of the storage mechanism 4. The four corners of the storage mechanism 4 are slidingly connected to the sliding rods 623, so that the storage mechanism 4 moves up and down along the sliding rods 623 during the lifting and lowering process of the storage mechanism 4.

[0058] The present application also provides a temporary storage device control method, which is applied to a temporary storage device. Figure 6 ,include:

[0059] S1. When a storage component 43 needs to load or unload materials, the controller 3 controls the driving mechanism 5 to move away from the storage mechanism 4.

[0060] Specifically, the storage components 43 can be loaded or unloaded according to a preset order, such as first-in-first-out or first-in-last-out, or a certain storage component 43 can be selected for loading or unloading. When loading or unloading starts, the controller 3 controls the moving component 52 to drive the driving component 51 to move away from the storage mechanism 4.

[0061] S2 , the controller 3 controls the lifting mechanism 6 to drive the storage mechanism 4 to move in the vertical direction until the storage assembly 43 is flush with the driving mechanism 5 .

[0062] Specifically, controller 3 controls the forward or reverse rotation of lift motor 611 to raise or lower storage mechanism 4. Lift motor 611 utilizes a servo motor, enabling precise control of the position of storage mechanism 4, eliminating the need for a separate position sensor. In practice, the direction and position of lift mechanism 6 can be controlled based on actual needs, thereby controlling the order in which storage assemblies 43 are loaded or unloaded.

[0063] S3. When the storage component 43 is flush with the drive mechanism 5, the controller 3 controls the drive mechanism 5 to move close to the storage component 43 and connect with the storage component 43 via the magnetic coupling 511.

[0064] Specifically, when the lifting mechanism 6 controls the storage mechanism 4 to rise and fall until the required storage component 43 is flush with the driving mechanism 5, the controller 3 controls the moving component 52 to drive the driving component 51 to move toward the direction close to the storage component 43, and connects the output shaft of the driving motor 512 and the driving shaft 431 of the storage component 43 through the magnetic coupling 511.

[0065] S4. The controller 3 controls the driving component 51 to drive the storage component 43 to load or unload materials.

[0066] Specifically, after the output shaft of the drive motor 512 is connected to the drive shaft 431 of the storage component 43, the drive motor 512 and the feeding motor 71 are controlled to rotate forward or reverse according to the required loading or unloading direction, so that the drive roller 433, the transmission roller 432, and the feeding roller 72 rotate forward or reverse, so that the PCB board processed in the previous process is sent into the storage component 43 through the transmission roller 432 and the feeding roller 72, or the PCB board stored in the storage component 43 is sent to the next process through the transmission roller 432 and the feeding roller 72.

[0067] For example, assuming that the current temporary storage device loads and unloads materials in a first-in-first-out order, the controller 3 first controls the lifting mechanism 6 to raise the storage mechanism 4 to the top or lower it to the bottom, starting from the storage component 43 on the bottom or top layer, and loading the materials in sequence from bottom to top or from top to bottom. After loading is completed, the storage mechanism 4 is usually at the bottom or top. When unloading is required, the controller 3 controls the lifting mechanism 6 to rise to the top or lower it to the bottom, and then starts from the storage component 43 on the bottom or top layer, and unloads the materials in sequence from bottom to top or from top to bottom, thereby realizing first-in-first-out loading and unloading.

[0068] The implementation principle of the embodiment of the present application is: through the coordinated control of the lifting mechanism 6 and the driving mechanism 5, stable loading and unloading of the temporary storage device is achieved, and the required storage components 43 can be selected in any order for loading or unloading through magnetic connection without manual adjustment, thereby improving the flexibility of the temporary storage device and the processing efficiency of the PCB board.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
