Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to an FCT testing device with protective function. Background Technology

[0002] FCT testing equipment is a functional testing device for printed circuit board assemblies after power-on. It is mainly used to verify whether the various performance parameters of the circuit board in a simulated operating environment meet the design requirements. It can accurately measure various parameters of electronic equipment, such as voltage, current, resistance, frequency, phase, etc., and analyze and process the measurement data to determine whether the equipment meets the specified technical indicators. It is widely used in online testing and final inspection of products to ensure that the quality and performance of products meet the requirements.

[0003] Existing patent (publication number: CN221650510U) discloses that "this utility model relates to the field of FCT test data acquisition technology, and discloses an FCT test data acquisition device, including an acquisition device body, a device base at the bottom of the acquisition device body, a device top cover at the top of the acquisition device body, four No. 1 fixing holes on the four sides of the upper half of the outer side of the acquisition device body, four No. 2 fixing holes on the four sides of the lower half of the outer side of the acquisition device body, and multiple spring structures on the four sides of the top of the device base. This FCT test data acquisition device exposes the important material feeding part of the upper half of the acquisition device body for operation by lowering the protective plate and fixing it with fixing screws passing through the No. 2 and No. 3 fixing holes. The protective plate is then raised by the spring structures and fixed with fixing screws passing through the No. 1 and No. 3 fixing holes, thus protecting the important material feeding part of the upper half of the acquisition device body."

[0004] In the process of developing this application, the inventors discovered the following problems with the prior art:

[0005] The FCT testing device protects the device by raising four protective plates and then fixing them with screws through fixing holes one and three, thus protecting the important upper part of the data collection device. However, installing and removing the protective plates requires a lot of time to tighten the screws, which seriously affects work efficiency. Furthermore, the existing device can only test one side of the test plate. After completing the test on one side, the worker must manually flip the test plate to test the other side, which increases the labor intensity of the workers.

[0006] Therefore, those skilled in the art have provided an FCT testing device with protective functions to solve the problems mentioned in the background art. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing an FCT testing device with protective functions. The flipping mechanism facilitates the flipping of the placement frame, thereby facilitating testing on both sides of the test plate. The protective mechanism protects the main body of the device from damage during transportation.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An FCT testing device with protective function includes a device body. The device body is provided with a flipping mechanism. The flipping mechanism includes a first motor. A placement frame is fixedly provided at the output end of the first motor. A second motor is fixedly provided at the front end of the placement frame. A bidirectional lead screw is fixedly provided at the output end of the second motor. Two sliders are externally threaded to the bidirectional lead screw. Multiple compression springs are fixedly provided at the lower ends of the two sliders. Two pressure plates are fixedly provided between the lower ends of the multiple compression springs.

[0010] The device body is provided with a protective mechanism, which includes a protective frame. A trapezoidal block is slidably arranged on one side of the protective frame. A second spring is fixedly arranged at the lower end of the trapezoidal block. A connecting rod is fixedly arranged at the lower end of the trapezoidal block. A handle is fixedly arranged on one side of the connecting rod. Inclined blocks are slidably arranged at both the front and rear ends of the trapezoidal block. A first spring is fixedly arranged between the two inclined blocks.

[0011] Furthermore, two support blocks are fixedly installed inside the main body of the device, and the first motor is externally fixedly installed inside one of the two support blocks.

[0012] Furthermore, the two sides of the placement frame are rotatably disposed on opposite sides of the two support blocks, and the two sliders are slidably disposed inside the placement frame.

[0013] Furthermore, a fixing rod is fixedly installed at the rear end of the placement frame, and the rear ends of both sliders are slidably installed outside the fixing rod.

[0014] Furthermore, multiple guide rods are fixedly installed at the lower outer end of the main body of the device, and the protective frame is slidably installed on the outside of the multiple guide rods. The two inclined blocks are slidably installed on the upper inner end of the protective frame, and two movable doors are hinged at the front end of the protective frame.

[0015] Furthermore, a slot is provided on the upper part of the main body of the device, the lower end of the second spring is fixedly installed inside the upper part of the protective frame, and the handle is slidably installed on one side of the protective frame.

[0016] Furthermore, safety light curtains are fixedly installed on opposite sides inside the main body of the device, and multiple casters are fixedly installed at the lower end of the main body of the device.

[0017] This utility model has the following beneficial effects:

[0018] 1. The present invention proposes an FCT testing device with protective function. When it is necessary to remove the protection of the device body by the protective frame, pull the handle to drive the connecting rod and the trapezoidal block to slide downward inside the protective frame, so that the contact between the inclined side and the inclined block is gradually released, causing the inclined block to retract into the protective frame, thereby releasing the connection between the inclined block and the slot. Subsequently, the protective frame will slide downward along the outside of the device body and the guide rod, thereby releasing the protection of the upper end of the device body. The installation and disassembly of the protective frame is relatively simple, without complicated tools or steps, thus improving work efficiency.

[0019] 2. The FCT testing device with protective function proposed in this utility model, when testing the test plate, is placed in the placement frame. Then, the second motor is started, causing the bidirectional lead screw to drive the slider to slide towards each other. When the slider moves to the appropriate position, the pressure plate will approach and contact the test plate. The pressure plate will slide upward and squeeze the compression spring, so that the pressure plate presses the test plate tightly. After the upper end face is tested, the first motor is started, driving the placement frame to rotate, so that the test plate is flipped. Then the testing device will test the other side of the test plate. The whole operation process is very convenient, and no manual flipping is required, which improves the convenience of operation and reduces the labor intensity of operators.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-5 One embodiment provided by this utility model:

[0031] An FCT testing device with protective function includes a device body 1. The device body 1 is equipped with a flipping mechanism 3. The flipping mechanism 3 includes a first motor 305. A placement frame 304 is fixedly installed at the output end of the first motor 305. A second motor 309 is fixedly installed at the front end of the placement frame 304. A bidirectional lead screw 308 is fixedly installed at the output end of the second motor 309. Two sliders 302 are externally threaded to the bidirectional lead screw 308. Multiple compression springs 307 are fixedly installed at the lower ends of the two sliders 302. Two pressure plates 306 are fixedly installed between the lower ends of the multiple compression springs 307. Two support blocks 301 are fixedly installed inside the device body 1. The first motor 305 is externally fixedly installed inside one of the two support blocks 301. The two sides of the placement frame 304 are rotatably installed on opposite sides of the two support blocks 301. The two sliders 302 are externally slidably installed inside the placement frame 304. A fixing rod 303 is fixedly installed at the rear end of the placement frame 304. The rear ends of the two sliders 302 are internally slidably installed outside the fixing rod 303.

[0032] Specifically, when testing the test board, the test board is first placed on the upper end of the placement frame 304. Then, the second motor 309 inside the placement frame 304 is started. The output end of the second motor 309 drives the bidirectional lead screw 308 to rotate inside the placement frame 304. Since both sliders 302 are threadedly connected to the bidirectional lead screw 308, when the bidirectional lead screw 308 rotates, it drives the sliders 302 to slide towards each other inside the placement frame 304. During this process, the sliders 302 slide outside the fixed rod 303, which plays a precise guiding role. The movement of the sliders 302 synchronously drives the pressure block at its lower end to move. When the sliders 302 slide to the appropriate position, the pressure block approaches and contacts the test board. At this time, the pressure plate 306 moves upward, causing the compression spring 307 to contract, thus releasing the pressure plate. The placement frame 304 can adapt to test plates of different thicknesses, and the lower end of the pressure plate 306 is made of a softer material, which can ensure the fixing effect while avoiding excessive pressure on the test plate and causing damage. Subsequently, the test plate can be firmly pressed, and the upper surface of the test plate can be tested. After the test of this surface is completed, the first motor 305 inside the support block 301 starts, driving the placement frame 304 to rotate between the support blocks 301. The placement frame 304 drives the test plate to flip over, and the testing device then unfolds to test the other side of the test plate. The whole process is convenient to operate, without the need for manual flipping, which improves the testing efficiency and reduces the cost of manual operation. The first motor 305 and the second motor 309 are both existing mature and publicly available technologies, and their specific structures and working principles will not be described in detail in this article.

[0033] Reference Figures 1-7 The main body 1 of the device is provided with a protective mechanism 4. The protective mechanism 4 includes a protective frame 401. A trapezoidal block 408 is slidably arranged on one side of the inner side of the protective frame 401. A second spring 409 is fixedly arranged at the lower end of the trapezoidal block 408. A connecting rod 410 is fixedly arranged at the lower end of the trapezoidal block 408. A handle 404 is fixedly arranged on one side of the connecting rod 410. Inclined blocks 402 are slidably arranged at both ends of the trapezoidal block 408. A first spring 407 is fixedly arranged between the two inclined blocks 402. Multiple guide rods 40 are fixedly arranged at the lower part of the outer side of the main body 1. 6. The protective frame 401 is slidably mounted on the outside of multiple guide rods 406. The two inclined blocks 402 are slidably mounted on the upper part of the protective frame 401. The front end of the protective frame 401 is hinged with two movable doors 403. The upper part of the device body 1 is provided with a slot 405. The lower end of the second spring 409 is fixedly mounted on the upper part of the protective frame 401. The handle 404 is slidably mounted on one side of the protective frame 401. The inside of the device body 1 is fixedly mounted on opposite sides with safety light curtains 2. The lower end of the device body 1 is fixedly mounted with multiple casters 5.

[0034] Specifically, when the main body 1 of the transport device is being transported, the protective frame 401 is pushed so that it slides outside the main body 1 and the guide rod 406. During this period, the inclined block 402 is squeezed and slides in the opposite direction inside the protective frame 401, and squeezes the first spring 407 connected to it, so that the first spring 407 contracts inside the protective frame 401. When the protective frame 401 moves to its final position, the first spring 407 rebounds, pushing the inclined block 402 back to its original position. The inclined block 402 is then embedded in the slot 405. At this time, the protective frame 401 is securely positioned on the upper part of the device body 1, providing good protection for the device body 1 and effectively preventing damage to the device from collisions that may occur during transportation. When it is necessary to release the protection of the upper part of the device body 1 by the protective frame 401, the handle 404 is pulled. The handle 404 drives the connecting rod 410 and the trapezoidal block 408 to slide downward inside the protective frame 401. During the descent of the trapezoidal block 408, it compresses the second spring 409 connected to it. At the same time, the contact between the inclined side of the trapezoidal block 408 and the inclined block 402 is gradually released. At this time, the first spring 407 retracts, and the two inclined blocks 402 slide towards each other inside the protective frame 401, retracting into the protective frame 401. The inclined block 402 is then disconnected from the slot 405. Subsequently, the protective frame 401 slides downward outside the device body 1 and the guide rod 406, smoothly releasing the protection of the upper part of the device body 1, making it convenient for operators to operate inside the device body 1. During the transportation process, the protective frame 401 can easily slide up to the upper part of the device body 1 for protection. By pulling the handle 404, the protective frame 401 can slide down to release the protection. The operation is simple, effectively protecting the device body 1 from collision damage during transportation, and quickly releasing the protection when it is necessary to operate inside the device, thus balancing the convenience of protection and operation.

[0035] The two hinged doors 403 at the front end of the protective frame 401 allow operators to easily access the front end of the main body 1 of the device while the protective frame 401 is closed. Meanwhile, the safety light curtain 2 located on opposite sides inside the main body 1 will immediately trigger a safety mechanism to stop the operation of the testing device when an object blocks the light in the light curtain, thus protecting the safety of the operators. The multiple casters 5 at the lower end of the main body 1 facilitate the movement and position adjustment of the entire testing device, making it convenient for use in different working scenarios.

[0036] Working principle: When testing the test board, the test board is first placed on the upper end of the placement frame 304. Then, the second motor 309 inside is started, causing the bidirectional lead screw 308 connected to its output end to rotate inside the placement frame 304. Since both sliders 302 are threadedly connected to the bidirectional lead screw 308, when the bidirectional lead screw 308 rotates, it will drive the sliders 302 to slide towards each other inside the placement frame 304. The movement of the sliders 302 will synchronously drive the pressure block at its lower end to move. When the sliders 302 move to the appropriate position, the pressure block will approach and contact the test board. At this time, the pressure plate 306 will move upward, causing the compression spring 307 to contract, thereby pressing the test board. Then, the upper end face is tested. After the test is completed, the first motor 305 inside the support block 301 is started, which will drive the placement frame 304 to rotate between the support blocks 301, thereby causing the placement frame 304 to flip the test board. At this time, the testing device will test the other side of the test board.

[0037] Secondly, when moving the main body 1 of the device, the protective frame 401 is pushed, causing it to slide outside the main body 1 and the guide rod 406. Subsequently, the inclined block 402 is squeezed, causing it to slide in the opposite direction inside the protective frame 401, and squeezing the first spring 407 connected to it, causing it to contract inside the protective frame 401. When the protective frame 401 moves to its final position, the first spring 407 rebounds, pushing the inclined block 402 back to its original position, so that it is embedded in the slot 405, making the protective frame 401 located at the upper part of the main body 1. When it is necessary to release the protection of the upper part of the main body 1 by the protective frame 401, the handle 404 is pulled. 04 will cause the connecting rod 410 and the trapezoidal block 408 to slide downward inside the protective frame 401. The descent of the trapezoidal block 408 will compress the second spring 409 connected to it, and the descent of the trapezoidal block 408 will gradually release the contact between its inclined side and the inclined block 402. At this time, the first spring 407 will retract, causing the two inclined blocks 402 to slide towards each other inside the protective frame 401, and retract into the protective frame 401, so that the inclined block 402 and the slot 405 are completely disconnected. At this time, the protective frame 401 will slide downward outside the device body 1 and the guide rod 406, thereby releasing the protection of the upper end of the device body 1.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
