Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of circuit board testing devices, specifically a circuit board testing device. Background Technology
[0002] A circuit board, also known as a printed circuit board, is an important basic component in electronic devices. It mainly consists of pads, vias, mounting holes, wires, components, connectors, fillers, and electrical boundaries. A circuit board testing device is a device used to test the performance and function of a circuit board. It can test various components on the circuit board to determine whether the circuit board meets the design requirements. A test bench is a very common member of circuit board testing devices.
[0003] In the circuit board manufacturing process, when a circuit board testing device is needed for assistance, the circuit board to be tested is first placed on the test bench. Then, the electric push column on the mounting bracket is activated, causing the test seat to move downwards until the metal probes on the test seat are in contact with the circuit board. At this point, specific signals and voltages are applied to the circuit board, and the output response and performance parameters of the circuit board are detected to determine whether the circuit board meets the requirements and whether there are any faults or defects. However, during the use of the test bench, the testing personnel need to frequently change the circuit boards on the test bench for testing. After a circuit board is tested, the testing personnel need to wait for the electric push column to retract and move the test seat upwards to a designated height before they can reach under the test seat to remove the tested circuit board. Then, they can place the untested circuit board on the test bench for testing. However, this method of removing the circuit board requires waiting for the test seat to move each time, which leads to a long testing time and affects the testing efficiency, thus affecting the use of the circuit board testing device.
[0004] To address the aforementioned problems, this application proposes a circuit board testing device. Utility Model Content
[0005] The purpose of this invention is to provide a circuit board testing device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a circuit board testing device, including a test platform, a mounting frame, and a testing seat. The mounting frame is welded to one side of the top of the test platform, and an electric push column is installed in the middle of the top of the mounting frame. The output end of the electric push column is connected to the testing seat. An auxiliary mechanism is provided on the outer wall of the testing seat. The auxiliary mechanism includes a bidirectional electric push rod, a slide rail, a transmission rod, a fixing pin, a guide rod, a shelf, a guide cavity, a storage box, a pulley, and a rubber pad. The bottom of the test platform is connected to the bidirectional electric push rod through the mounting seat. The output end of the bidirectional electric push rod is slidably connected to the slide rail, and a transmission rod is welded to the outer wall of the slide rail.
[0007] Preferably, a fixing pin is rotatably connected to the middle of the transmission rod, and a guide rod is rotatably connected to the top of the transmission rod.
[0008] Preferably, the side of the guide rod away from the transmission rod is connected to a placement plate via a rotating seat, and a guide cavity is provided in the center of the top of the test platform.
[0009] Preferably, the test platform is connected to a storage box via a storage cavity, and the bottom two sides of the storage box are fitted with pulleys, and the inner wall of the storage box is connected with a rubber pad.
[0010] Preferably, the outer wall of the test bench is provided with an adjustment mechanism, and the adjustment mechanism includes a fixed motor, gears, racks, guide seats, worktables, limit posts and limit seats, and the outer wall of the test bench is connected to the fixed motor through a support platform.
[0011] Preferably, the output end of the fixed motor is connected to a gear, and the outer wall of the gear is meshed with a rack.
[0012] Preferably, a guide seat is slidably connected to the outer wall of the rack, and a worktable is welded to the top of the rack.
[0013] Preferably, a limiting post is welded to the side of the bottom of the workbench away from the rack, and a limiting seat is slidably connected to the outer wall of the limiting post, and the outer wall of the limiting seat is welded to the test bench.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this circuit board testing device, the tested circuit board can be removed during the upward movement of the test seat through the auxiliary mechanism, thus eliminating the need to wait for the test seat to move to the designated height before removing the circuit board, thereby saving time and improving work efficiency. The adjustable mechanism makes the height of the workbench correspond to the height of the tester, making it convenient for the tester to pick up the circuit board for testing. Thus, when using the circuit board testing device, the height of the workbench can be easily adjusted.
[0015] 1. When a circuit board testing device is needed to assist in the circuit board production process, the bidirectional electric push rod is first activated to make the transmission rod rotate along the fixed pin. At this time, the angle between the guide rod and the transmission rod changes, which causes the placement plate to move away from each other until the circuit board on the placement plate falls into the storage box through the guide cavity. Then, there is no need to wait for the test seat to move up to the specified height before taking away the tested circuit board, thus saving time and improving work efficiency. Therefore, when using the circuit board testing device, it plays a role in improving work efficiency.
[0016] 2. When a circuit board testing device is needed to assist in the circuit board production process, the fixed motor is first started to drive the gear to rotate. Then, the rotation of the gear causes the rack to move the worktable until the worktable moves to the specified height, so that the height of the worktable corresponds to the height of the tester. This makes it convenient for the tester to pick up the circuit board for testing. Thus, when using the circuit board testing device, it plays a role in facilitating the adjustment of the worktable height. Attached Figure Description

[0024] 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.
[0025] Please see Figures 1-4This utility model provides a technical solution: a circuit board testing device, including a test bench 1, a mounting frame 2, and a testing seat 4. The mounting frame 2 is welded to one side of the top of the test bench 1, and an electric push column 3 is installed in the middle of the top of the mounting frame 2. The output end of the electric push column 3 is connected to the testing seat 4. An auxiliary mechanism 5 is provided on the outer wall of the testing seat 4. The auxiliary mechanism 5 includes a bidirectional electric push rod 501, a slide rail 502, a transmission rod 503, a fixing pin 504, a guide rod 505, a shelf 506, a guide cavity 507, a storage box 508, a pulley 509, and a rubber pad 510. The bidirectional electric push rod 501 is connected to the bottom of the test bench 1 through the mounting seat, and the output end of the bidirectional electric push rod 501 is slidably connected to the slide rail 502. A transmission rod is welded to the outer wall of the slide rail 502. 503; A fixing pin 504 is rotatably connected to the middle of the transmission rod 503, and a guide rod 505 is rotatably connected to the top of the transmission rod 503; A shelf 506 is connected to the side of the guide rod 505 away from the transmission rod 503 through a rotating seat; A guide cavity 507 is opened in the middle of the top of the test platform 1; A storage box 508 is connected to the test platform 1 through a storage cavity, and pulleys 509 are connected to both sides of the bottom of the storage box 508, and a rubber pad 510 is connected to the inner wall of the storage box 508; Limiting cavities corresponding to the shelf 506 are opened on both sides of the top of the test platform 1; The fixing pin 504 is fixedly connected to the test platform 1, and the shelf 506 is slidably connected to the test platform 1; The shelf 506 is symmetrically distributed about the vertical center line of the test platform 1; A metal probe is provided at the bottom of the detection seat 4.
[0026] In practical implementation, when a circuit board testing device is needed to assist in the circuit board production process, in order to improve work efficiency and allow the testing personnel to quickly remove the tested circuit boards, the bidirectional electric push rod 501 is activated first. Since the output end of the bidirectional electric push rod 501 is slidably connected to the slide rail 502, when the bidirectional electric push rod 501 retracts, its output end moves along the slide rail 502, thereby generating a pulling force on the transmission rod 503, causing the transmission rod 503 to rotate along the fixed pin 504. Furthermore, since the top end of the transmission rod 503 is rotatably connected to the guide rod 505, the rotation of the transmission rod 503 drives the guide rod 505 to rotate.
[0027] At this time, the angle between the guide rod 505 and the transmission rod 503 changes, causing the placement plate 506 to move away from each other until the circuit board on the placement plate 506 falls into the storage box 508 through the guide cavity 507. At this time, the rubber pad 510 reduces the impact between the circuit board and the storage box 508, preventing damage to the circuit board. Then, as the electric push column 3 retracts and drives the detection seat 4 to move upward, the tested circuit board can be removed without waiting for the detection seat 4 to move to the designated height before removing the tested circuit board. This saves the time required to test a single circuit board and improves work efficiency. Therefore, when using the circuit board testing device, it plays a role in improving work efficiency.
[0028] Next, the bidirectional electric push rod 501 is activated to extend, causing the shelves 506 to move closer together until they are in contact. The circuit board to be tested is then placed on the shelf 506. Then, the electric push column 3 is activated to extend and move the test seat 4 downward. The pulley 509 assists the staff in moving the storage box 508, thereby removing the tested circuit board from the storage box 508. The tested circuit board is then removed during the process of the test seat 4 moving downward to test the circuit board, thus saving time and making it easier for subsequent circuit boards to enter the storage box 508.
[0029] See Figure 1 , Figure 2 and Figure 5 It is known that the outer wall of the test bench 1 is provided with an adjustment mechanism 6, and the adjustment mechanism 6 includes a fixed motor 601, a gear 602, a rack 603, a guide seat 604, a workbench 605, a limiting post 606, and a limiting seat 607. The outer wall of the test bench 1 is connected to the fixed motor 601 through a support platform; the output end of the fixed motor 601 is connected to the gear 602, and the outer wall of the gear 602 is meshed with the rack 603; the outer wall of the rack 603 is slidably connected to the guide seat 604, and the top of the rack 603 is welded to the workbench 605; the bottom end of the workbench 605 is welded to the side away from the rack 603, and the outer wall of the limiting post 606 is slidably connected to the limiting seat 607, and the outer wall of the limiting seat 607 is welded to the test bench 1; the outer wall of the guide seat 604 is welded to the test bench 1, and the rack 603 and the limiting post 606 are parallel to each other.
[0030] In practice, when a circuit board testing device is needed to assist in the circuit board production process, in order to facilitate the testers to easily pick up untested circuit boards, the height of the workbench 605 needs to be adjusted so that the height of the circuit boards on the workbench 605 corresponds to the testers' usage habits and height. First, the fixed motor 601 is started. Since the output end of the fixed motor 601 is connected to the gear 602, the start of the fixed motor 601 drives the gear 602 to rotate. Since the gear 602 and the rack 603 are meshed, the rotation of the gear 602 causes the rack 603 to move up and down along the guide seat 604. Since the top of the rack 603 is welded to the workbench 605, the movement of the rack 603 drives the workbench 605 to move together.
[0031] Because the bottom side of the workbench 605 is welded to the limiting post 606, the limiting post 606 moves along the limiting seat 607, thereby guiding the movement of the workbench 605 until the workbench 605 moves to the specified height. Then, the height of the workbench 605 is automatically adjusted so that the height of the workbench 605 corresponds to the height of the tester, making it convenient for the tester to pick up the circuit board for testing. Thus, when the circuit board testing device is used, it plays the role of facilitating the adjustment of the height of the workbench 605.
[0032] In summary, when using this circuit board testing device, the circuit board to be tested is first placed on the test bench 1. Then, the electric push column 3 on the mounting bracket 2 is activated, causing the test seat 4 to move downwards until the metal probe on the test seat 4 contacts the circuit board. At this time, a specific signal and voltage are applied to the circuit board, and the output response and performance parameters of the circuit board are detected to determine whether the circuit board meets the requirements for faults or defects. This is existing technology and will not be elaborated on here. The circuit board can be removed during the upward movement of the test seat 4 by the auxiliary mechanism 5, thus eliminating the need to wait for the test seat 4 to move to the specified height before removing the circuit board, thereby saving time and improving work efficiency. The height of the workbench 605 is adjusted by the adjustment mechanism 6 to correspond to the height of the tester, making it convenient for the tester to pick up the circuit board for testing. The contents not described in detail in this description are existing technologies known to those skilled in the art.
[0033] Although the present invention 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 invention should be included within the protection scope of the present invention.
