Description

Technical Field

[0001] The utility model relates to the technical field of integrated circuit FPC, in particular to an FPC board lifting and storing device. Background Art

[0002] In the manufacturing process of Flexible Printed Circuit (FPC), the solder mask exposure process is one of the key processes. The process first involves printing solder mask ink on the FPC, followed by pre-baking to cure the ink; after pre-baking, the FPC board is discharged, which means placing the board in an appropriate position for subsequent steps; next, the ink is irradiated with a solder mask light source system, with the aim of polymerizing and hardening the ink in a specific area through photocuring technology; then, the unpolymerized ink is removed through a development step, leaving a precise ink pattern, thus completing the entire solder mask process.

[0003] Since the FPC board may warp after pre-baking, this warping phenomenon will cause deviation in the position of the board when unloading. This deviation will affect the positioning accuracy of the suction cup material picking mechanism. The position of the suction cup may be inconsistent each time the material is picked up, which not only affects the accuracy of the subsequent solder mask exposure, but may also lead to reduced production efficiency and product quality problems. Summary of the invention

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the problem in the prior art that the FPC board is warped after pre-baking, which causes the position of the board to deviate during material discharge and affects the positioning accuracy of the material.

[0011] In one embodiment of the present invention, the frame includes a bottom plate and a vertical plate installed on the bottom plate, and the vertical guide assembly includes a guide sleeve installed on the bottom plate and a guide column slidably connected to the guide sleeve.

[0015] In one embodiment of the present utility model, the lifting drive device includes a motor.

[0016] The above technical solution of the utility model has the following advantages compared with the prior art:

[0017] The utility model discloses an FPC board lifting and storing device, which can dynamically adjust the position according to the surface height of the FPC board stored on the material pallet by setting a lifting adjustment component and a detection component, thereby ensuring that the suction cup can operate at the optimal height each time the material is taken, thereby solving the problem of placement deviation caused by FPC that may be warped after pre-baking, and can significantly reduce the material taking error caused by the warping of the board, thereby improving the automation level of the production line and the accuracy of repeated operations.

[0034] Reference Figure 1 , Figure 2 As shown, the utility model is an FPC board lifting and storing device, comprising:

[0035] Frame 1;

[0036] The material support plate 2 is installed on the frame 1 in a liftable manner and is stacked with FPC boards;

[0037] A vertical guide assembly 3 is installed at the bottom end of the material support plate 2 and extends to the bottom end of the frame 1, and the vertical guide assembly 3 is installed with a movable plate;

[0038] The lifting adjustment assembly 4 includes a lifting drive device 41 installed at the bottom end of the frame 1, a lead screw 42 connected to the lifting drive device 41 and extending away from the bottom end of the frame 1, and a nut 43 slidably connected to the lead screw 42 and connected to the movable plate;

[0039] The detection component 5 is used to detect the surface height of the FPC boards stacked on the material pallet 2.

[0040] Since the FPC board may warp after pre-baking, this warping phenomenon will cause deviation in the board position when unloading, and this deviation will affect the positioning accuracy of the suction cup picking mechanism. Through the above settings, the surface height of the FPC board can be automatically adjusted according to the material after picking, without manual adjustment, ensuring that the suction cup can operate at the optimal height each time the material is picked up, which is very important for FPC boards that may warp after pre-baking. It can significantly reduce the picking errors caused by board warping and improve the automation level of the production line and the accuracy of repeated operations.

[0041] In one embodiment, the frame 1 includes a bottom plate 11 and a vertical plate 12 mounted on the bottom plate 11, and the vertical guide assembly 3 includes a guide sleeve 31 mounted on the bottom plate 11 and a guide column 32 slidably connected to the guide sleeve 31. The lifting drive device 41 includes a motor.

[0042] The height of the material support plate 2 is adjusted by the automatic lifting system, which reduces the need for manual intervention, thereby reducing the labor intensity of the operator and improving the convenience and safety of the operation. The lifting adjustment component 4 composed of the motor, the lead screw 42, etc. can achieve fast and accurate adjustment to adapt to the height of different FPC boards, making the production process smoother.

[0043] In one embodiment, the material support plate 2 is of a rectangular structure, and four guide pillars 32 are symmetrically distributed along the center of the material support plate 2 .

[0044] In one embodiment, the detection assembly 5 includes a group of laser emitting sensors 51 and laser receiving sensors 52 mounted on the vertical plate 12 and arranged opposite to each other. The laser emitting sensor 51 and the laser receiving sensor 52 can monitor the surface height of the FPC board on the material pallet 2 in real time, ensure the accuracy of the material position, help maintain the consistency of product quality, and improve overall production efficiency.

[0045] It should be understood that the laser emitting sensor 51 emits a beam of laser in the direction of the laser receiving sensor 52, ensuring that the laser can be transmitted directly from the emitting sensor to the receiving sensor in the absence of any medium blocking it. When the material pallet 2 carrying the FPC board gradually rises, the FPC board stacked on it gradually approaches the laser path, and the FPC board rises to a height sufficient to block the laser path. The light beam emitted by the laser emitting sensor 51 will be blocked by the surface of the FPC board. At this time, the laser receiving sensor 52 will not be able to receive the laser signal, and a signal interruption will occur. After the receiving sensor detects the laser signal interruption, it will send a signal to the control system, indicating that the material pallet 2 has reached the correct height. At this time, the control system will control the lifting drive device 41 to stop rising and fix it in the current position.

[0046] In one embodiment, a rectangular material placement area 21 is formed on the material pallet 2, and the frame 1 is also equipped with a first positioning laser transceiver sensor group 6 arranged along the length direction of the material placement area 21 and a second positioning laser transceiver sensor group 7 arranged along the diagonal direction of the material placement area 21, which can ensure that the material picking position of the plate picking mechanism 8 is consistent each time.

[0047] The laser transmitter in the first positioning laser transceiver sensor group 6 or the second positioning laser transceiver sensor group 7 sends a laser beam, and the laser receiver receives the laser at the corresponding position on the opposite side or diagonal line. When the FPC board on the material pallet 2 is located in the laser path, the laser is blocked or reflected by the material, and the sensor determines the exact position of the FPC board by the change in the received laser signal; using two groups of laser transceiver sensors, respectively along the length direction and the diagonal direction, can greatly improve the positioning accuracy, monitor the position of the FPC board from two different directions, thereby reducing the error that may occur in a single direction and improving the overall measurement accuracy.

[0048] Working principle: Before production begins, the FPC board to be exposed and the spacer paper are first placed on the material placement area 21 of the material tray 2. At this time, the lifting drive device 41 (motor) and the entire system are reset to zero;

[0049] The lifting drive device 41 is started, and the material support plate 2 starts to rise. During the rising process, when the laser emission sensor 51 and the laser receiving sensor 52 detect the surface height position of the FPC board stacked on the material support plate 2, the lifting drive device 41 stops, and the board taking mechanism 8 descends and sucks up the material. After that, the board taking mechanism 8 (including one or more suction cups) descends to the upper end position of the material, and then sucks up the top FPC board for subsequent processing;

[0050] As production continues, the number of FPC boards on the material pallet 2 gradually decreases. In order to maintain the material picking mechanism to be able to pick up materials at a high height every time, the lifting drive device 41 continuously drives the material pallet 2 to rise to a predetermined height based on feedback from the laser emission and receiving sensors.

[0051] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
