Description

Technical Field

[0001] This application belongs to the technical field of FPC board processing, and relates to an FPC board loading device. Background Technology

[0002] FPC boards, also known as flexible printed circuit boards or flexible circuit boards, are characterized by high wiring density, light weight, and thinness. Because they can be freely bent, folded, and rolled, and can move and stretch freely in three-dimensional space, they achieve lightweighting, miniaturization, and thinness, thus integrating components and wire connections. They play a pivotal role in electronic components and are mainly used in many products such as mobile phones, laptops, PDAs, digital cameras, and aerospace.

[0003] After the FPC board is processed in the production line, the processed FPC board needs to be placed on a conveyor belt and transported to the inspection station for quality inspection. Usually, workers place the processed FPC boards on the conveyor belt one by one. The above-mentioned technology has the disadvantages of low manual efficiency and high cost. Summary of the Invention

[0004] In order to improve the efficiency of FPC board loading and reduce the labor cost of FPC board loading, this application provides an FPC board loading device.

[0005] The FPC plate loading device provided in this application adopts the following technical solution:

[0006] An FPC board loading device includes a mounting platform, a conveyor belt adjacent to the mounting platform, a receiving platform mounted on the mounting platform, a lifting drive, a transfer drive mechanism, and a gripping mechanism connected to the output end of the transfer drive mechanism. The conveyor belt is used to transport FPC boards. The receiving platform is slidably mounted on the mounting platform in a vertical direction and is used to support the FPC boards. The lifting drive is used to drive the receiving platform to slide in a vertical direction. The transfer drive mechanism is located above the receiving platform and is used to drive the gripping mechanism to reciprocate between the receiving platform and the conveyor belt. The gripping mechanism is used to horizontally grip the FPC boards.

[0007] By adopting the above technical solution, several FPC boards are stacked sequentially on the receiving platform. The transfer drive mechanism drives the gripping mechanism to move above the receiving platform. After the gripping mechanism grabs the stacked FPC boards on the receiving platform, it is driven by the transfer drive mechanism to move to the conveyor belt. The gripping mechanism places the FPC boards on the conveyor belt, thereby completing the loading of FPC boards and reducing labor costs. During the loading process, as the number of FPC boards on the receiving platform decreases, the lifting drive component drives the receiving platform to gradually move upward, so that the distance between the topmost FPC board and the gripping mechanism remains consistent, which facilitates subsequent gripping and improves the loading efficiency of FPC boards.

[0008] Optionally, the mounting platform is provided with a plurality of limiting rods, which pass through the material receiving platform. The plurality of limiting rods form a limiting space for accommodating the FPC board. When the FPC board is placed on the material receiving platform, the FPC board contacts the plurality of limiting rods simultaneously.

[0009] By adopting the above technical solution, during the vertical movement of the receiving platform, several limiting rods restrict the FPC board within the limiting space, minimizing the change in the position of the FPC board due to the vibration of the receiving platform during the movement of the receiving platform and the gripping of the FPC board, thereby improving the accuracy of gripping the FPC board and placing it on the conveyor belt.

[0010] Optionally, the mounting platform is provided with a guide rod, which passes through the material receiving platform and is slidably connected to it. The length direction of the guide rod is parallel to the sliding direction of the material receiving platform.

[0011] By adopting the above technical solution, the guide rod plays a guiding role in the movement of the material receiving platform, making the material receiving platform more stable during the sliding process.

[0012] Optionally, a distance measuring device is provided on the mounting platform, the distance measuring device is located above the material receiving platform, and the distance measuring device is used to measure the distance between itself and the material receiving platform.

[0013] By adopting the above technical solution, the remaining number of FPC boards stacked on the platform can be easily determined by measuring the distance between the measuring device and the platform, thus facilitating timely replenishment of FPC boards and further improving the loading efficiency of FPC boards.

[0014] Optionally, the gripping mechanism includes a connecting frame, a mounting frame, a gripping drive, and a gripping assembly. One end of the connecting frame is connected to the output end of the transfer drive mechanism. The mounting frame is slidably connected to the other end of the connecting frame in the vertical direction. The gripping drive is disposed on the connecting frame and is used to drive the mounting frame to move in the vertical direction. The gripping assembly is disposed on the mounting frame and is used to grip the FPC board horizontally.

[0015] By adopting the above technical solution, the gripping component can move vertically, which facilitates the gripping of FPC boards on the support platform and the smooth placement of FPC boards on the conveyor belt.

[0016] Optionally, the mounting frame is provided with a limiting mechanism and a limiting drive mechanism. The limiting mechanism is slidably disposed at the edge of the mounting frame and is located at the end of the mounting frame whose orientation is opposite to the conveyor belt's conveying direction. The limiting mechanism is disposed adjacent to the gripping component. The limiting mechanism is provided with a limiting through groove for inserting the edge of the FPC board horizontally gripped by the gripping component. The limiting drive mechanism is used to drive the limiting mechanism to move towards or away from the gripping component.

[0017] By adopting the above technical solution, since the FPC board is a flexible material, it is prone to deformation. After the FPC board is picked up, its edges naturally droop and bend downwards. When the processed FPC board is placed on the moving conveyor belt, the end of the FPC board facing the opposite direction of the conveyor belt slides and rubs against the moving conveyor belt, which can easily cause the FPC board to undergo greater bending deformation, affecting the positioning accuracy of the FPC board on the conveyor belt, and even causing damage to the FPC board. Before picking up the FPC board, the limit drive mechanism drives the limit mechanism to move to the FPC. Outside the board area range, after the gripping component picks up the FPC board, the limiting drive mechanism drives the limiting mechanism to move closer to the FPC board, so that the end of the FPC board closest to the gripping limiting mechanism is inserted into the limiting through slot; when the FPC board is placed on the conveyor belt, the end of the FPC board away from the limiting mechanism and the middle of the FPC board contact the conveyor belt in sequence. Driven by the conveyor belt, the FPC board is pulled out from the limiting through slot, thus completing the loading of the FPC board. This avoids the end of the FPC board facing the opposite direction of the conveyor belt contacting the conveyor belt first, thereby improving the above-mentioned problem.

[0018] Optionally, the limiting mechanism includes a mounting plate, a limiting plate slidably disposed on the mounting plate in a vertical direction, and an adjusting drive component disposed between the mounting plate and the limiting plate. The mounting plate is slidably connected to the mounting frame, and the output end of the limiting drive mechanism is connected to the mounting plate. The limiting plate is located between the mounting plate and the material receiving platform. The mounting plate and the limiting plate form the limiting through groove, and the adjusting drive component is used to drive the limiting plate to move in a vertical direction.

[0019] By adopting the above technical solution, the width of the limiting slot can be easily adjusted according to the different flexibility of different FPC board models, so that FPC boards with different degrees of downward bending at the edges can be inserted into the limiting slot, thereby improving the adaptability of the limiting slot to different FPC board models.

[0020] Optionally, the adjustment drive includes two racks rotatably mounted on the mounting bracket, two gears rotatably mounted on the mounting plate, two internally threaded tubes coaxially and fixedly connected to the two gears, and two screws fixedly mounted on the limiting plate. The two gears mesh with the two racks simultaneously, the rotation axes of the two internally threaded tubes are parallel to each other, and the two screws are threadedly connected to the two internally threaded tubes. When the mounting plate slides closer to the gripping assembly, the limiting plate moves closer to the mounting plate.

[0021] By adopting the above technical solution, when the adjustment mechanism is located at the position farthest from the gripping component, the distance between the limiting plate and the mounting plate is the largest. As the adjustment mechanism gradually moves closer to the gripping component, the gear and the internal threaded tube rotate, and the screw drives the limiting plate to move closer to the mounting plate through the threaded transmission. As the FPC plate gradually enters the limiting through groove, the distance between the limiting plate and the mounting plate gradually decreases. During the process of the FPC plate being inserted into the limiting through groove, the downward-bent end of the FPC plate is straightened upward, further improving the limiting effect of the limiting component.

[0022] Optionally, a guide ramp is provided on one side surface of the limiting plate near the mounting plate at the end near the gripping component.

[0023] By adopting the above technical solution, it is convenient to insert the FPC board into the limiting through groove, and during the process of the FPC board sliding out of the limiting through groove, the guide slope plays a guiding role in the sliding of the FPC board, making the FPC board slide out of the limiting through groove more smoothly.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Improved FPC board loading efficiency and reduced labor costs;

[0026] 2. The gripping and placement process of FPC boards is more stable, improving the accuracy of FPC board loading;

[0027] 3. Improved the problem that when the FPC board is placed on a moving conveyor belt, the end of the FPC board facing the opposite direction of the conveyor belt will slide and rub against the moving conveyor belt due to the natural drooping and downward bending of the FPC board edges. This can easily cause the FPC board to undergo greater bending deformation, affecting the positioning accuracy of the FPC board on the conveyor belt, and even causing damage to the FPC board.

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] This application discloses an FPC (Flexible Printed Circuit) plate loading device. (Refer to...) Figure 1An FPC board loading device includes a mounting platform 1, a conveyor belt 2 adjacent to the mounting platform 1, a receiving platform 3 mounted on the mounting platform 1, a lifting drive 4, a transfer drive mechanism 5, and a gripping mechanism 6 connected to the output end of the transfer drive mechanism 5. The conveyor belt 2 is used to transport FPC boards. The receiving platform 3 is slidably mounted on the mounting platform 1 in a vertical direction and is used to support the FPC boards. The lifting drive 4 is used to drive the receiving platform 3 to slide vertically. The transfer drive mechanism 5 is located above the receiving platform 3 and is used to drive the gripping mechanism 6 to reciprocate between the receiving platform 3 and the conveyor belt 2. The gripping mechanism 6 is used to horizontally grip the FPC boards. Several FPC boards are stacked sequentially on the receiving platform 3. The transfer drive mechanism 5 drives the gripping mechanism 6 to move above the receiving platform 3. After the gripping mechanism 6 grabs the stacked FPC board on the receiving platform 3, the transfer drive mechanism 5 drives the gripping mechanism 6 to move to the conveyor belt 2. The gripping mechanism 6 places the FPC board on the conveyor belt 2, thus completing the loading of the FPC board and reducing labor costs. During the loading process, as the number of FPC boards on the receiving platform 3 decreases, the lifting drive component 4 drives the receiving platform 3 to gradually move upward, so that the distance between the topmost FPC board and the gripping mechanism 6 remains consistent, which facilitates subsequent gripping and improves the loading efficiency of the FPC board.

[0036] Reference Figure 1 The lifting drive component 4 drives the material receiving platform 3 to move vertically via a motor screw drive. Two vertically arranged guide rods 11 are fixedly installed on the mounting frame 62. The two guide rods 11 pass through the material receiving platform 3 and are slidably connected to the material receiving platform 3. The guide rods 11 guide the movement of the material receiving platform 3, making the material receiving platform 3 more stable during sliding. Four limiting rods 12 are fixedly installed on the mounting frame 62. The limiting rods 12 pass through the material receiving platform 3 and form a limiting space 121 for accommodating the FPC board. When the FPC board is placed on the material receiving platform 3, the FPC board contacts the four limiting rods 12 simultaneously. During the vertical movement of the material receiving platform 3, the limiting rods 12 restrict the FPC board within the limiting space 121, minimizing the change in the position of the FPC board due to the vibration of the material receiving platform 3 during the movement of the material receiving platform 3 and the grasping of the FPC board, thereby improving the accuracy of grasping the FPC board and placing it on the conveyor belt 2.

[0037] Reference Figure 1 A distance measuring element 13 is provided on the mounting frame 62. The distance measuring element 13 is a distance measuring instrument located above the material support platform 3. The distance measuring instrument is used to measure the distance between itself and the material support platform 3. By measuring the distance between the distance measuring element 13 and the material support platform 3, it is easy to know the remaining number of FPC boards stacked on the material support platform 3, so as to facilitate timely replenishment of FPC boards and further improve the loading efficiency of FPC boards.

[0038] Reference Figure 1 and Figure 2 The transfer drive mechanism 5 is a motor screw slide module. The gripping mechanism 6 includes a connecting frame 61, a mounting frame 62, a gripping drive component 63, and a gripping assembly 64. One end of the connecting frame 61 is connected to the output end of the transfer drive mechanism 5. The mounting frame 62 is slidably connected to the other end of the connecting frame 61 in the vertical direction. The gripping drive component 63 is a cylinder, which is mounted on the connecting frame 61 and drives the mounting frame 62 to move in the vertical direction. The gripping assembly 64 includes an air pump 641 and four vacuum suction cups 642 mounted on the mounting frame 62 and connected to the air pump 641. The four vacuum suction cups 642 are arranged in a rectangular shape and are used to grip FPC boards horizontally. The gripping assembly 64 can move in the vertical direction, which facilitates gripping the FPC boards on the receiving platform 3 and placing the FPC boards stably on the conveyor belt 2.

[0039] Reference Figure 1 and Figure 2 A limiting mechanism 7 and a limiting drive mechanism 8 are provided at the end of the mounting frame 62 facing in the opposite direction to the conveyor belt 2. The limiting mechanism 7 includes a mounting plate 71, a limiting plate 72 slidably mounted on the mounting plate 71 in the vertical direction, and an adjusting drive component 73 disposed between the mounting plate 71 and the limiting plate 72. The mounting plate 71 is slidably connected to the mounting frame 62, and the straight line of the sliding direction of the mounting plate 71 is parallel to the straight line of the conveyor belt 2. The output end of the limiting drive mechanism 8 is connected to the mounting plate 71 and drives the mounting plate 71 to slide through a motor screw drive. The limiting plate 72 is located below the mounting plate 71 and between two adjacent limiting rods 12, allowing the limiting plate 72 to pass between the two limiting rods 12. The mounting plate 71 and the limiting plate 72 are parallel to each other and form a limiting through groove 74 between them. The adjusting drive component 73 drives the limiting plate 72 to move in the vertical direction.

[0040] Reference Figure 2 and Figure 3Because FPC sheets are flexible materials, they are prone to deformation. After being picked up, the edges of the FPC sheet naturally droop and bend downwards. When the processed FPC sheet is placed on the moving conveyor belt 2, the end of the FPC sheet facing the opposite direction to the conveyor belt 2 experiences sliding friction with the conveyor belt 2, which can easily cause the FPC sheet to undergo greater bending deformation, affecting the accuracy of the FPC sheet's placement on the conveyor belt 2, and even causing damage to the FPC sheet. Before picking up the FPC sheet, the limiting drive mechanism 8 drives the limiting mechanism 7 to move outside the area of ​​the FPC sheet. After component 64 picks up the FPC board, the limiting drive mechanism 8 drives the limiting mechanism 7 to move closer to the FPC board, so that the end of the FPC board closest to the limiting mechanism 7 is inserted into the limiting slot 74. When the FPC board is placed on the conveyor belt 2, the end of the FPC board away from the limiting mechanism 7 and the middle part of the FPC board come into contact with the conveyor belt 2 in sequence. Driven by the conveyor belt 2, the FPC board is pulled out from the limiting slot 74, thus completing the loading of the FPC board. This avoids the end of the FPC board facing the opposite direction of the conveyor belt 2 from contacting the conveyor belt 2 first, thereby improving the above-mentioned problem.

[0041] Reference Figure 2 and Figure 3 The adjusting drive component 73 includes two racks 731 integrally fixed on the mounting bracket 62, two gears 732 rotatably mounted on the mounting plate 71, two internally threaded tubes 733 coaxially fixedly connected to the two gears 732, and two screws 734 fixedly mounted on the limiting plate 72. The length direction of the racks 731 is parallel to the sliding direction of the mounting plate 71. The two gears 732 mesh with the two racks 731 simultaneously. The rotation axes of the two gears 732 are both vertical. The two screws 734 are threadedly connected to the two internally threaded tubes 733. When the mounting plate 71 slides towards the gripping component 64, the limiting plate 72 moves towards the mounting plate 71.

[0042] Reference Figure 3 and Figure 4 When the adjustment mechanism is at its furthest position from the gripping component 64, the distance between the limiting plate 72 and the mounting plate 71 is at its maximum. As the adjustment mechanism gradually moves closer to the gripping component 64, the gear 732 and the internal threaded tube 733 rotate, and the screw 734 drives the limiting plate 72 to move closer to the mounting plate 71 through the threaded transmission. As the FPC board gradually enters the limiting through groove 74, the distance between the limiting plate 72 and the mounting plate 71 gradually decreases. During the process of the FPC board being inserted into the limiting through groove 74, the downward-bent end of the FPC board is straightened upward, further improving the limiting effect of the limiting component.

[0043] Reference Figure 3 and Figure 4The limiting plate 72 has a guide slope 721 on the side surface near the mounting plate 71, near the gripping component 64. This facilitates the insertion of the FPC board into the limiting slot 74, and the guide slope 721 guides the FPC board as it slides out of the limiting slot 74, making the FPC board slide out of the limiting slot 74 more smoothly.

[0044] The implementation principle of the FPC board loading device in this application embodiment is as follows: Several FPC boards are stacked sequentially on the receiving platform 3. The transfer drive mechanism 5 drives the gripping mechanism 6 to move above the receiving platform 3. After the gripping mechanism 6 grips the stacked FPC board on the receiving platform 3, the transfer drive mechanism 5 drives the gripping mechanism 6 to move to the conveyor belt 2. The gripping mechanism 6 places the FPC board on the conveyor belt 2, thereby completing the loading of the FPC board and reducing labor costs. During the loading process, as the number of FPC boards on the receiving platform 3 decreases, the lifting drive component 4 drives the receiving platform 3 to gradually move upward, so that the distance between the topmost FPC board and the gripping mechanism 6 remains consistent, which facilitates subsequent gripping and improves the loading efficiency of the FPC board.
