Description

Technical Field

[0001] This utility model belongs to the field of FPC flexible board testing and design, and particularly relates to a multi-station testing component and a production line testing device. Background Technology

[0002] Flexible printed circuit boards (FPCs) are printed circuit boards made using flexible substrates. Unlike traditional rigid printed circuit boards, FPCs are bendable, foldable, and wrappable, allowing them to be freely shaped in three-dimensional space, making them suitable for products with complex shapes or space constraints. FPCs are widely used in various electronic products, such as mobile phones, laptops, digital cameras, medical devices, and automotive electronic systems. Due to their thinness and flexibility, they are particularly suitable for applications requiring space and weight savings, and are also a key technology for achieving miniaturization and high-density assembly.

[0003] In FPC testing with microphones, to accommodate multi-station testing, the equipment is often a multi-unit interconnected production line, including a loading machine, a film peeling inspection machine, a film applying machine, a post-film applying inspection machine, and a unloading machine, with a total length exceeding 5 meters. This results in significant wasted space. Currently, most equipment on the market for testing 3C-related FPC flexible boards automatically handles the transfer and placement between multiple testing stations. The main drawback of this type of testing production line is its length and large space requirement. Summary of the Invention

[0004] The purpose of this utility model embodiment is to provide a multi-station testing component, which aims to solve the problems of large space occupation and low production efficiency caused by the lengthy production line of multiple testing stations.

[0005] This utility model embodiment is implemented as follows: a multi-station testing component, the multi-station testing component comprising: frame; A turntable is rotatably mounted on the frame. At least four stations are arranged in a ring on the turntable for placing workpieces, including one loading station and one unloading station, with the rest being testing stations. The loading station is adjacent to the unloading station. A central axis is located at the center of the turntable, and the turntable rotates around the central axis. The top plate assembly is mounted on the frame and located above the test station, for testing the workpiece at the test station.

[0006] Furthermore, a carrier plate is provided on the loading station, unloading station and the testing station. The carrier plate is connected to a vacuum adsorption module for fixing the workpiece on the station. A slip ring is fitted on the central shaft, and several sets of air passages are provided on the slip ring, which are correspondingly connected to the vacuum adsorption module.

[0007] Furthermore, the number of workstations on the turntable is four, and the turntable rotates 90° each time.

[0008] Furthermore, a loading robot is provided on one side of the loading station, and a unloading robot is provided on one side of the unloading station.

[0009] Furthermore, a top plate is provided on the frame, the top plate is located above the testing station, and the top plate assembly is provided below the top plate. The top plate assembly includes: The ceiling panel is slidably connected to the top panel in a longitudinal position via a guide rod; The drive module, connected to the top plate, is used to drive the ceiling plate to press down; A testing module, installed on the top plate, is used to test the workpiece at the testing station.

[0010] Another objective of this utility model embodiment is to provide a production line testing device, which includes the aforementioned multi-station testing component. The multi-station testing component is disposed in a corner of the production line testing device, the testing station is located in the corner position, and the loading station and the unloading station are located in non-corner positions.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0014] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0015] In the first embodiment, such as Figure 1-4 As shown, a multi-station testing component 900 is proposed, the multi-station testing component 900 comprising: 100 racks; A turntable 200 is rotatably mounted on the frame 100. At least four workstations are arranged in a ring on the turntable 200 for placing workpieces, including a loading workstation 210 and a unloading workstation 220, and the rest are testing workstations 230. The loading workstation 210 and the unloading workstation 220 are adjacent to each other. A central axis 300 is disposed at the center of the turntable 200, and the turntable 200 rotates about the central axis 300. The top plate assembly 400 is mounted on the frame 100 and located above the test station 230 for testing the workpieces on the test station 230.

[0016] In this embodiment, the design concept of the multi-station testing component 900 is to integrate two or more adjacent testing stations with similar cycle times into one, thereby improving space utilization and reducing the cycle time (CT time) between testing stations.

[0017] In this embodiment, as Figure 1 and3 As shown, each station is equipped with a carrier plate. The number of carrier plates is variable and can be selected according to the actual production situation. In this embodiment, as an example, two carrier plates are provided at each station, and each carrier plate can hold one FPC workpiece. This embodiment integrates two adjacent test workpieces together, so there must be at least two test stations 230. Each test station 230 performs electrical testing through a needle die, mainly testing the electrical connectivity, insulation, and basic functions of the FPC. In this embodiment, the stations on the turntable 200 can be arranged clockwise, such as loading station 210 - testing station 230 - unloading station 220, or counterclockwise, such as unloading station 220 - testing station 230 - loading station 210. The key is to integrate multiple test stations on the same turntable 200 structure. In this embodiment, since robotic arms are often used to handle materials on assembly line equipment, there is a top plate assembly 400 for testing above the test carrier plate (i.e. above the test station 230). The robotic arm and the top plate assembly 400 are prone to mechanical interference. Therefore, adjacent loading stations 210 and unloading stations 220 are reserved on the turntable 200 in this embodiment.

[0018] As an optional solution in this embodiment, such as Figure 1 As shown, a four-station turntable mechanism with equal spacing is suitable. The four evenly distributed turntables 200 are intermittently rotated by servo motors in conjunction with a hollow rotary platform to complete testing and material handling. During the brief period after each rotation of the four-station turntable 200, the loading robot from the previous station places the FPC product onto the carrier plate at the loading station 210, while the unloading robot removes the tested product from the carrier plate at the unloading station 220 and places it into the shipping tray. The two adjacent testing top plate assemblies 400 in the middle stations press down to test the products on their respective carrier plates. After testing, the top plate 410 retracts, and the turntable 200 rotates 90° to enter the next cycle.

[0019] In one optional embodiment, such as Figure 5 As shown, the carrier plate is connected to the vacuum adsorption module and is used to fix the workpiece on the workstation. A slip ring 310 is sleeved on the central shaft 300, and several sets of air passages 320 are provided on the slip ring 310. The air passages 320 are correspondingly connected to the vacuum adsorption module. In this embodiment, considering that each carrier plate can be compatible with vacuum adsorption and its own cylinder, in order to ensure that the air pipes can move orderly with the carrier plate without interfering with each other during rotation, a slip ring 310 is added on the axis of the turntable 200. The slip ring 310 drives the air passages 320 to rotate synchronously with the turntable 200, ensuring the order and neatness of the overall air passages 320. For a turntable 200 with four workstations and two carrier plates at each workstation, an eight-in-eight-out air passage 320 can be set on the slip ring 310.

[0020] In this embodiment, a top plate 110 is provided on the frame 100, the top plate 110 is located above the test station 230, and the top plate assembly 400 is provided below the top plate 110. The top plate assembly 400 includes: The ceiling panel 410 is slidably connected to the top plate 110 in a longitudinal position via a guide rod; The drive module 420 is connected to the top plate 110 and is used to drive the ceiling plate 410 to press down. The test module 430 is mounted on the top plate 410 and is used to test the workpiece at the test station 230.

[0021] In this embodiment, the top plate 110 is mounted on the frame 100, serving to support the top plate assembly 400. The top plate 110 is positioned directly opposite the testing station 230, avoiding interference with the loading station 210 and unloading station 220, thus preventing collisions between the robot arm and the top plate assembly 400. The drive module 420, typically a pneumatic or electric cylinder, is positioned above the top plate 110 and is used to drive the top plate 410 downwards, causing the testing module 430 to press against the carrier plate, allowing the probe of the needle die to contact the test contacts of the FPC workpiece, thereby achieving electrical testing. This type of testing module 430 is an existing structure, generally including a probe, a spring structure, and a guide post. The spring structure extends and retracts to allow the probe to extend and contact the test contacts, while the guide post provides positioning and guidance, ensuring the accuracy of the needle puncture test.

[0022] In the second embodiment, as Figure 6 As shown, a production line testing device is proposed. The production line testing device includes the multi-station testing component 900. The multi-station testing component 900 is disposed in a corner of the production line testing device. The testing station 230 is located in the corner position, while the loading station 210 and the unloading station 220 are located in non-corner positions.

[0023] In this embodiment, as Figure 6 As shown, the assembly line testing equipment includes assembly line 500, film peeling station 600, internal hole inspection station 700, film application station 800, and multi-station testing assembly 900. The material flow direction of the workpieces is sequentially from the loading section of assembly line 500 (…). Figure 6 The assembly line consists of: 500 (left side), film peeling station 600, internal hole inspection station 700, film application station 800, multi-station testing assembly 900, and the assembly line loading section. Figure 6(Right side of assembly line 500). The film-removing station 600 is used to remove the film layer from the workpiece surface; the internal hole inspection station 700 is used to check for foreign objects and scratches in the internal holes; the film-applying station 800 is used to apply film to the FPC workpiece; and the multi-station testing component 900 is used for electrical testing. In this embodiment, the multi-station testing component 900 integrates multiple testing stations and is located in the upper right corner of the assembly line testing equipment. This reduces the equipment size and improves upon the cumbersome drawbacks of current long assembly line testing equipment, using a more reasonable multi-process testing layout to improve space occupancy. It is understood that the upper right corner mentioned in this embodiment is only relative and can be placed in other corners of the square assembly line testing equipment according to actual conditions.

[0024] Working principle: Taking the four-station turntable 200 as an example, the loading robot places the FPC workpiece into the carrier plate of the loading station 210. The turntable 200 rotates 90°, and the top plate assembly 400 above the two test stations 230 presses down to complete the test. The turntable 200 then rotates 90° again, and the unloading robot takes away the FPC workpiece from the unloading station 220.

[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
