Abstract
Description
Technical Field

[0002] In today's rapidly developing electronics industry, flexible printed circuit boards (FPCs), with their unique advantages of being thin, light, bendable, and foldable, are widely used in smartphones, tablets, wearable devices, automotive electronics, and many other fields, becoming an indispensable key component in modern electronic devices. During the production process, due to the influence of various factors such as material properties, process parameters, and environmental conditions, the dimensions of FPCs may shrink or expand relative to their design dimensions; that is, FPCs experience expansion and contraction. If this expansion and contraction problem is not effectively controlled, it can cause misalignment in the assembly of FPCs with related components, leading to a series of problems such as poor electrical connections and excessive mechanical stress.
[0003] Currently, the expansion and contraction detection of FPC products is carried out using traditional manual inspection methods. Manual inspection mainly relies on the operator's visual observation and simple measuring tools, such as calipers and micrometers. Manual inspection is difficult to meet the high precision requirements of expansion and contraction detection for FPC products and cannot detect minute expansion and contraction problems in time, thus affecting the quality and performance of the products.

Therefore, they should not be construed as limitations on this utility model.
[0024] like Figure 1As shown, an automatic product expansion and contraction detection device includes a support frame 1 and an adsorption platform 2. The adsorption platform 2 is slidably connected to the support frame 1 along a first direction. The top of the adsorption platform 2 is constructed as a plane to support flexible sheet-like products. The support frame 1 is provided with a pressing mechanism 3 and a detection mechanism 4, which moves vertically towards the adsorption platform 2 to flatten the product and accurately reflect its dimensions. The detection mechanism 4 has translational degrees of freedom along the first and second directions. The detection end of the detection mechanism 4 performs dimensional detection on the product located on the adsorption platform 2 and compares it with the design dimensions to automatically determine whether the product has experienced dimensional expansion or contraction.
[0025] like Figure 2 As shown, the support frame 1 is fixedly provided with a first guide rail 11 along the first direction. In this embodiment, the first guide rail 11 is an electric linear module, and the adsorption platform 2 is slidably connected to the first guide rail 11 along the first direction. The top of the adsorption platform 2 is provided with a plurality of adsorption holes, and the plurality of adsorption holes are arrayed and distributed on the adsorption platform 2 for adsorbing the product onto the top plane of the platform.
[0026] The pressing mechanism 3 includes a pressure plate 31 and a lifting cylinder 32. The cylinder body of the lifting cylinder 32 is fixedly mounted on the support frame 1. The piston rod of the lifting cylinder 32 extends and retracts vertically upwards. The pressure plate 31 is fixedly connected to the piston rod of the lifting cylinder 32. In this embodiment, a lifting cylinder 32 is provided on each of the support frames 1 on both sides of the first guide rail 11. The pressure plate 31 is horizontally positioned above the first guide rail 11. The two sides of the pressure plate 31 are fixedly connected to the piston rod of a lifting cylinder 32. The two lifting cylinders 32 synchronously drive the pressure plate 31 to move towards the first guide rail 11, so that the pressure plate 31 can close to the adsorption platform 2 to flatten the product on the adsorption platform 2. In this embodiment, the pressure plate 31 is transparent glass. After the pressure plate 31 covers the product on the adsorption platform 2, the detection mechanism 4 directly detects the product. In other embodiments, after the pressure plate 31 covers the product on the adsorption platform 2, the lifting cylinder 32 drives the pressure plate 31 to rise. After the adsorption platform 2 and the pressure plate 31 separate, the size detection is performed.
[0027] like Figure 3As shown, the detection mechanism 4 includes a first track 41 and a second track 42. The first track 41 is mounted on a first guide rail 11. Specifically, the first track 41 is fixedly connected to the support frame 1 via a frame, which elevates the first track 41 so that it is located on top of the first guide rail 11, with space between the first guide rail 11 and the first track 41 for the adsorption platform 2 to pass through. The first track 41 spans across the top of the first guide rail 11 along a second direction. The second track 42 slides along the second direction and is connected to the first track 41. The second track 42 extends along a first direction and is slidably connected to a vision inspection module 43 along the second direction. The pressure plate 31 is located within the moving area of the vision inspection module 43. Driven by the first track 41 and the second track 42, the vision inspection module 43 measures the dimensions of the product to compare with the design dimensions and determine whether the product has expanded or contracted. Preferably, both the first track 41 and the second track 42 are equipped with grating rulers to detect the actual displacement of the movement of the first track 41 and the second track 42, and transmit the position signal to the control system in real time to compensate for the error of mechanical transmission, avoid positioning deviation caused by mechanical clearance or slippage, and improve the accuracy of dimensional detection.
[0028] The support frame 1 is equipped with a feeding mechanism 5 and a feeding bin 6. The feeding mechanism 5 is used to transfer the product in the feeding bin 6 to the adsorption platform 2. The feeding bin 6 is fixed on the support frame 1. The top of the feeding bin 6 is open, and the interior of the feeding bin 6 is divided into multiple vertical cavities. In this embodiment, the feeding bin 6 is divided into four chambers.

The fourth track 522 extends in the second direction, and the stroke of the fourth track covers one end of the feeding bin 6 and the first guide rail 11. The first adsorption component 51 is slidably connected to the fourth track 522 in the second direction. The first adsorption component 51 includes a support plate 511 and a plurality of adsorption nozzles 512. The support plate 511 is horizontally arranged, and the plurality of adsorption nozzles 512 are fixedly connected to the bottom of the support plate 511. Each chamber of the feeding bin 6 corresponds to at least one adsorption nozzle 512, so that the adsorption nozzles 512 can adsorb and remove the product in the feeding bin 6. Preferably, each adsorption nozzle 512 is controlled independently, that is, each adsorption nozzle 512 will not interfere with each other when adsorbing products.
[0030] The support frame 1 is fixedly equipped with a visual correction component 53 facing the top opening of the feeding bin 6. The visual correction component 53 is electrically connected to the feeding mechanism 5. A lifting cylinder 61 is fixedly installed at the bottom of the feeding bin 6. The piston rod of the lifting cylinder 61 extends vertically upward from inside the feeding bin 6 to lift the product inside the feeding bin 6, so that the visual correction component 53 can detect the position of the product. The visual correction component 53 detects the position of the product in the feeding bin 6 and feeds it back to the feeding mechanism 5. The first drive component 52 adjusts the position of the product during the product transfer process.
[0031] The support frame 1 is fixedly equipped with a partition compartment 7. The top of the partition compartment 7 is open, and the partition compartment 7 is divided into multiple mutually isolated chambers by partitions. The chambers of the partition compartment 7 are connected to the opening along the setting direction. After the product expansion and contraction test is completed, the next station arm will retrieve the material from the partition compartment 7. That is, the partition compartment 7 is used to store products in different states, and the partition compartment categorizes and stores expanded and contracted products and non-expanded and non-expanded products. The second track 42 is fixedly equipped with a second adsorption assembly 44, which is used to transfer the products that have completed the expansion and contraction test into the partition compartment 7. Preferably, the second adsorption assembly 44 has multiple negative pressure nozzles, and more preferably, the multiple adsorption nozzles 512 are arranged in a single row. Preferably, after the product expansion and contraction test is completed,
