Description

Technical Field

[0001] This application relates to the field of FPC transport equipment, and in particular to an FPC lifting platform. Background Technology

[0002] Flexible printed circuit boards (FPCs) are an important part of the electronics industry, and after their production, they need to be protected through efficient packaging processes.

[0003] In flexible circuit board production lines, the lifting and handling of materials mainly rely on manual labor or traditional conveying equipment. Manual labor lifts the flexible circuit boards and places them on the processing equipment, but manual handling is inefficient and the force is not accurately controlled, which can easily damage the flexible circuit boards. When traditional conveying equipment lifts the flexible circuit boards, it is difficult to meet the needs of height adjustment and precise positioning in the production of flexible circuit boards. This affects the lifting and transportation efficiency and the flexible circuit boards are also prone to falling off the traditional conveying equipment. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an FPC lifting platform.

[0005] The FPC lifting platform provided in this application adopts the following technical solution:

[0006] An FPC lifting trolley includes a trolley body, a lifting frame, a lifting assembly, a receiving assembly, and a negative pressure assembly. The lifting frame is installed at one end of the trolley body, which provides transportation. The lifting assembly is installed on the lifting frame, and its lifting end moves along the lifting frame. The receiving assembly is connected to the lifting end, and the lifting end synchronously provides lifting and lowering of the receiving assembly, with the product placed on the receiving assembly. The negative pressure assembly is installed on the lifting frame or the trolley body, and its negative pressure end is connected to the receiving assembly, providing negative pressure adsorption for the product.

[0007] By adopting the above technical solution, the flexible circuit board is placed on the receiving component, and the negative pressure end of the negative pressure component is used to adsorb the flexible circuit board onto the receiving component, which prevents the flexible circuit board from falling off the receiving component during the movement of the vehicle body or the lifting component. At the same time, there is no need for rigid clamping or pressing, which provides protection for the flexible circuit board and prevents damage to the flexible circuit board during transportation.

[0008] Optionally, the lifting assembly includes a drive unit, a gear unit, a first rack, and a first limiting block; the drive unit is mounted on the lifting frame, and the drive end is connected to the gear unit; the lifting frame is provided with a limiting port, the first limiting block is embedded in the limiting port, and is slidably connected to the limiting port; the first rack is connected to the first limiting block and meshes with the gear unit; the receiving assembly is located outside the lifting frame and is connected to the limiting block.

[0009] By adopting the above technical solution, when the drive unit provides the gear unit to rotate, it can drive the first rack to move up and down along the limiting port through the first limiting block. The receiving component is located outside the lifting frame and is connected to the side of the first limiting block located outside the lifting frame, so that when the limiting block moves up and down along the limiting port, it can synchronously drive the receiving component and the flexible circuit board placed on the receiving component to move up and down synchronously.

[0010] Optionally, the lifting assembly further includes a second rack; the lifting frame has limiting ports on both sides in opposite directions, one limiting port has a first limiting block and the other limiting port has a second limiting block; the second rack is connected to the second limiting block and meshes with the gear part, and when the gear part rotates, the first rack and the second rack move in opposite directions.

[0011] By adopting the above technical solution, when the drive unit drives the gear unit to rotate, the first rack and the second rack move up and down in opposite directions, so that the first limit block and the second limit block move in opposite directions. Simultaneously, the receiving component connected to the first limit block and the second limit block moves in opposite directions. The rising receiving component can send the flexible circuit board into the raised equipment, while the falling receiving component can put in the flexible circuit board. The filling and feeding are alternated in sequence, which speeds up the conveying efficiency.

[0012] Optionally, the receiving component includes a receiving platform; the receiving platform is provided with a plurality of adsorption grooves, and the adsorption grooves are connected to the negative pressure component.

[0013] By adopting the above technical solution, the receiving platform has sufficient area to place the flexible circuit board, and multiple adsorption tanks can work with the negative pressure component to provide multiple negative pressure adsorption points, so that the flexible circuit board is adsorbed by multiple adsorption points, thus ensuring the stability of the transport.

[0014] Optionally, ventilation channels are provided between adjacent adsorption tanks.

[0015] By adopting the above technical solution, after the ventilation channels of adjacent adsorption tanks are connected, the negative pressure component only needs to provide negative pressure to one of the adsorption tanks to generate negative pressure in all adsorption tanks, thereby improving the flexibility of negative pressure supply.

[0016] Optionally, a protective pad is provided on the receiving platform.

[0017] By adopting the above technical solution, the protective pad can increase the friction between the pad and the flexible circuit board. At the same time, the soft material of the protective pad can prevent the flexible circuit board from being scratched or damaged, thus ensuring the stable transport of the flexible circuit board.

[0018] Optionally, the negative pressure assembly includes an exhaust fan and a negative pressure hose; the exhaust fan is installed on the vehicle body or the lifting frame, and one end of the negative pressure hose is connected to the exhaust fan, while the other end is connected to the adsorption tank.

[0019] By adopting the above technical solution, the exhaust fan uses a negative pressure hose to draw air, so that the negative pressure hose is located at the adsorption tank and generates negative pressure suction, which allows the adsorption tank to stably adsorb the flexible circuit board onto the surface of the receiving platform.

[0020] Optionally, the lifting frame is provided with an observation window above the gear section.

[0021] By adopting the above technical solution, the observation window allows the vehicle to observe road conditions from above while it is moving, thus improving the safety of transportation.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The flexible circuit board is placed on the receiving component, and the negative pressure end of the negative pressure component is used to adsorb the flexible circuit board onto the receiving component, so as to prevent the flexible circuit board from falling off the receiving component during the movement of the vehicle body or the lifting component. At the same time, there is no need for rigid clamping or pressing, which provides protection for the flexible circuit board and prevents damage to the flexible circuit board during the transportation process.

[0024] 2. When the drive unit provides the gear unit to rotate, it can drive the first rack to move up and down along the limiting port through the first limiting block. The receiving component is located outside the lifting frame and is connected to the side of the first limiting block located outside the lifting frame, so that when the limiting block moves up and down along the limiting port, it can synchronously drive the receiving component and the flexible circuit board placed on the receiving component to move up and down synchronously.

[0025] 3. When the drive unit drives the gear unit to rotate, the first rack and the second rack move up and down in opposite directions, so that the first limit block and the second limit block move in opposite directions. Simultaneously, the receiving component connected to the first limit block and the second limit block moves in opposite directions. The rising receiving component can send the flexible circuit board into the raised equipment, while the falling receiving component can put in the flexible circuit board. The filling and feeding are alternated in sequence to speed up the conveying efficiency.

[0026] 4. The receiving platform has sufficient area to place flexible circuit boards, and multiple adsorption tanks can work with the negative pressure component to provide multiple negative pressure adsorption points, allowing the flexible circuit boards to be adsorbed by multiple adsorption points, thus ensuring stable transport.

[0036] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0037] This application discloses an FPC lifting platform.

[0038] An FPC lifting trolley is used to transport and lift FPC boards, which become flexible circuit boards or products.

[0039] refer to Figure 1 As shown, it includes a vehicle body 1, a lifting frame 2, a lifting assembly 3, a receiving assembly 4, and a negative pressure assembly 5. The vehicle body 1 can adopt different volumes or styles according to requirements. In this embodiment, a hand-pushed two-wheeled vehicle body 1 is used as an example. The lifting frame 2 is installed at one end of the vehicle body 1. It can be set at the front or rear of the vehicle body 1 as required, so as to facilitate the transportation of flexible circuit boards by the vehicle body 1.

[0040] The lifting frame 2 has a rectangular frame structure, which has a certain load-bearing capacity and structural stability. The lifting component 3 is installed on the lifting frame 2, and the lifting end moves along the lifting frame 2. The lifting component 3 can provide lifting drive for the flexible circuit board, so that the flexible circuit board is lifted along the lifting frame 2.

[0041] The receiving component 4 is connected to the lifting end, and the lifting end synchronously provides lifting and lowering of the receiving component 4. The receiving component 4 is used to receive and place the product. At the same time, when the lifting end moves up and down along the lifting frame 2, it synchronously drives the receiving component 4 to move up and down, thereby achieving the function of lifting the product.

[0042] The negative pressure component 5 is installed on the lifting frame 2 or the vehicle body 1, and the negative pressure end is connected to the receiving component 4, providing negative pressure adsorption to the product. After the negative pressure component 5 generates negative pressure, it can make the receiving component 4 have negative pressure adsorption force, so that the flexible circuit board can be adsorbed on the receiving component 4 during the lifting process, preventing the flexible circuit board from falling off the receiving component 4.

[0043] Specifically, the flexible circuit board is placed on the receiving component 4, and the negative pressure end of the negative pressure component 5 is used to adsorb the flexible circuit board onto the receiving component 4, so as to prevent the flexible circuit board from falling off the receiving component 4 during the movement of the vehicle body 1 or the lifting component 3. At the same time, there is no need for rigid clamping or pressing, which provides protection for the flexible circuit board and prevents damage to the flexible circuit board during the transportation process.

[0044] Further reference Figure 2 As shown, the lifting assembly 3 includes a drive unit 31, a gear unit 32, a first rack 33, and a first limit block 34. The drive unit 31 is installed on the lifting frame 2, and the drive end is connected to the gear unit 32. The drive unit 31 can be a servo motor for driving. The drive unit 31 can be provided with a connecting frame, which is connected to the inner wall of the lifting frame. The drive unit 31 can drive the gear unit 32 to rotate.

[0045] The lifting frame 2 is provided with a limiting port 21. The first limiting block 34 is embedded in the limiting port 21 and is slidably connected to the limiting port 21. The limiting port 21 provides a limit for the first limiting block 34 to prevent the first limiting block 34 from falling out of the limiting port 21. The first limiting block 34 can be an I-shaped block. The width of the middle part of the I-shaped block is smaller and matches the width of the limiting port 21, so that it can be embedded in the limiting port 21 and slide along the limiting port 21. The width of the two sides of the I-shaped block is greater than the width of the limiting port 21, so that it cannot be removed from the limiting port 21.

[0046] The first rack 33 is connected to the first limiting block 34 and meshes with the gear part 32. The first rack 33 and the first limiting block 34 are connected on one side inside the lifting frame 2. After the first rack 33 meshes with the gear part 32, when the drive part 31 provides the gear part 32 to rotate, it can drive the first rack 33 to move up and down along the limiting port 21 through the first limiting block 34. The receiving component 4 is located outside the lifting frame 2 and is connected to the side of the first limiting block 34 outside the lifting frame 2, so that when the limiting block moves up and down along the limiting port 21, it can synchronously drive the receiving component 4 and the flexible circuit board placed on the receiving component 4 to move up and down synchronously.

[0047] Furthermore, refer to Figure 2 As shown, the lifting assembly 3 also includes a second rack 35; the lifting frame 2 has a limiting port 21 on both sides in the opposite direction, a first limiting block 34 is provided in one limiting port 21, and a second limiting block 36 is provided in the other limiting port 21, so that the first limiting block 34 and the second limiting block 36 on both sides can move up and down along their respective limiting ports 21.

[0048] The second rack 35 is connected to the second limiting block 36 and meshes with the gear part 32, so that the first rack 33 and the second rack 35 are respectively meshed on both sides of the gear part 32. Therefore, when the gear part 32 rotates, the first rack 33 and the second rack 35 move in opposite directions. That is, when the first rack 33 rises through the first limiting block 34, the second rack 35 falls through the second limiting block 36, and vice versa.

[0049] Specifically, when the drive unit 31 drives the gear unit 32 to rotate, the first rack 33 and the second rack 35 move up and down in opposite directions, causing the first limit block 34 and the second limit block 36 to move in opposite directions. Simultaneously, the receiving component 4 connected to the first limit block 34 and the second limit block 36 moves in opposite directions. This allows the first limit block 34 to drive the corresponding receiving component 4 to rise, while the second limit block 36 drives the corresponding receiving component 4 to fall. This enables the rising receiving component 4 to feed the flexible circuit board into the raised equipment, while the falling receiving component 4 can place the flexible circuit board inside. This alternating filling and feeding process accelerates the conveying efficiency.

[0050] In some embodiments, reference Figure 2 and Figure 3 As shown, the receiving component 4 includes a receiving platform 41, on which a plurality of adsorption grooves 411 are provided. The adsorption grooves 411 are connected to the negative pressure component 5. The receiving platform 41 has sufficient area to provide a place for the flexible circuit board. The multiple adsorption grooves 411 can cooperate with the negative pressure component 5 to provide multiple negative pressure adsorption points, so that the flexible circuit board is adsorbed by multiple adsorption points, thus ensuring the stability of the transport.

[0051] Furthermore, ventilation channels 412 are provided between adjacent adsorption tanks 411. After the ventilation channels 412 are connected between adjacent adsorption tanks 411, the negative pressure component 5 only needs to provide negative pressure to one of the adsorption tanks 411 to generate negative pressure in all adsorption tanks 411, thereby improving the flexibility of negative pressure supply.

[0052] Furthermore, refer to Figure 2 and Figure 3 As shown, a protective pad 42 is provided on the receiving platform 41. The protective pad 42 can increase the friction between the flexible circuit board and the receiving platform. At the same time, the soft material of the protective pad 42 can prevent the flexible circuit board from being scratched or damaged, and ensure the stable transport of the flexible circuit board. The protective pad 42 can be made of rubber.

[0053] The protective pad 42 can also be replaced with a plastic pad or a silicone pad.

[0054] In some embodiments, reference Figure 2 As shown, the negative pressure component 5 includes an exhaust fan 51 and a negative pressure hose 52. The exhaust fan 51 is installed on the vehicle body 1 or the lifting frame 2. The figure shows the lifting frame 2 as an example. One end of the negative pressure hose 52 is connected to the exhaust fan 51, and the other end is connected to the adsorption tank 411. The exhaust fan 51 uses the negative pressure hose 52 to draw air, so that the negative pressure hose 52 is located at the adsorption tank 411 and generates negative pressure suction. The adsorption tank 411 can then stably adsorb the flexible circuit board onto the surface of the receiving platform 41.

[0055] The negative pressure hose 52 used in the negative pressure component 5 can be a rubber hose or a plastic hose, allowing the pipe to expand and contract freely to adapt to the lifting effect of the lifting component 3.

[0056] Furthermore, the outer wall of the lifting frame 2 is provided with a limiting ring 23, and the negative pressure hose 52 passes through the limiting ring 23 and connects to the receiving platform 41. The limiting ring 23 can prevent the negative pressure hose 52 from swinging randomly.

[0057] In some embodiments, reference Figure 2 As shown, the lifting frame 2 is provided with an observation window 22 above the gear part 32, so that when the vehicle body 1 is moving, the field of vision can go over the observation window 22 to observe the road conditions when moving.

[0058] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
