Description

Technical Field

[0001] This invention relates to the field of electronic hardware testing technology, and in particular to a hardware testing device for electronic information engineering. Background Technology

[0002] In the development of electronic devices, circuit boards, as core components, directly affect the performance of the entire system due to their reliability and stability. The complex wiring and precise connections of various electronic components on circuit boards make them susceptible to environmental factors and wear and tear during operation, leading to circuit board failures. For example, poor connections or component damage can cause the circuit board to lose its function or the overall performance of the device to decline, thus affecting the normal use of the device. Therefore, a hardware testing device for electronic information engineering is needed to test circuit boards and ensure the quality of circuit board products.

[0003] A hardware testing device for electronic information engineering, with announcement number CN222212601U, has solved the technical drawback of the lack of dust removal on the circuit board surface before using a camera to detect whether there are burnt areas on the circuit board surface. This dust may affect the camera's ability to detect burnt areas on the circuit board surface. However, similar structures still have many defects in actual use. For example, traditional testing devices mostly use continuous conveying methods. The circuit board is in a continuous state of motion during the transmission process. Vibration or displacement can easily cause the testing mechanism to fail to accurately capture the detection area, resulting in missed detections or false detections. At the same time, testing devices that cannot be continuously conveyed require manual adjustment, which is inefficient and difficult to adapt to the needs of automated production.

[0004] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention proposes a hardware testing device for electronic information engineering. This device addresses the problem that circuit boards are in continuous motion during transmission, and vibration or offset can cause the testing mechanism to fail to accurately capture the testing area, resulting in missed or false detections. Furthermore, testing devices that cannot be continuously transported require manual adjustment, leading to low efficiency and difficulty in adapting to the needs of automated production.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows:

[0007] A hardware testing device for electronic information engineering includes a housing, a transmission mechanism, and a positioning mechanism. It also includes a testing mechanism fixedly installed on the top wall of the housing and an intermittent feeding mechanism fixedly installed on one side of the transmission mechanism. A temporary storage box is fixedly installed on one side of the top of the transmission mechanism. The transmission mechanism is installed through the inside of the housing. An installation plate is fixedly installed inside the housing. The positioning mechanism is installed through the installation plate. The transmission mechanism is connected to the intermittent feeding mechanism and the positioning mechanism respectively.

[0008] The intermittent feeding mechanism and the positioning mechanism are driven to operate synchronously by the transmission mechanism. The intermittent feeding mechanism separates the circuit boards stored in the temporary storage box in an intermittent manner and transports the separated circuit boards to the component transmission mechanism. The transmission mechanism then smoothly transports the circuit boards to the positioning mechanism, which intermittently positions the transported circuit boards to ensure their stability during inspection. The positioning mechanism, in conjunction with the transmission mechanism, releases the inspected circuit boards one by one. The process of intermittent material distribution, equidistant conveying, intermittent positioning, and release of circuit boards is completed through the linkage of the transmission mechanism with the intermittent feeding mechanism and the positioning mechanism.

[0009] Preferably, the transmission mechanism comprises two side plates, tension rollers, a conveyor belt, a drive motor, a synchronous pulley, driven conveyor rollers, a driving conveyor roller, a supplementary light, and a guide assembly. The two side plates are fixedly installed inside the housing, with an opening at the top of one side plate and a through guide assembly installed on one side of the other side plate.

[0010] Preferably, the guiding assembly consists of an electric push rod and a guiding plate. The electric push rod is fixedly installed on one side of the side plate, and the guiding plate is movably installed on the other side of the side plate. The output end of the electric push rod passes through the side plate and is fixedly connected to the guiding plate. The position of the guiding plate is adjusted by the electric push rod.

[0011] Preferably, the positioning mechanism comprises an intermittent limiting component, a locking claw, an intermittent unlocking component, and a transmission bevel gear set. The intermittent limiting component is mounted through the mounting plate, the locking claw is rotatably mounted on the bottom of the mounting plate, and the intermittent unlocking component is rotatably mounted on the bottom of the mounting plate. The locking claw is dynamically engaged with the intermittent limiting component, and the intermittent unlocking component is dynamically abutting against the locking claw. The output end of the transmission bevel gear set is fixed to the bottom of the intermittent unlocking component, and the input end of the transmission bevel gear set is fixedly connected to one end of the active transmission toothed roller.

[0012] Preferably, the intermittent limiting component consists of a rotating disk, a slotted disk, and four limiting rubber rods. The rotating disk is rotatably mounted on the top of the mounting plate, the slotted disk is rotatably mounted on the bottom of the mounting plate, and the bottom of the rotating disk is fixedly connected to the slotted disk through a connecting seat. The four limiting rubber rods are arranged in a ring array on the outer side of the rotating disk.

[0013] Preferably, the intermittent unlocking assembly consists of a lifting base, a spring element, and a rotating cam. The lifting base is fixedly installed at the bottom of the mounting plate, the rotating cam is rotatably installed at the bottom of the lifting base, one end of the spring element is installed on one side of the lifting base via a shaft bolt, and the other end of the spring element is connected to the locking claw via a shaft bolt.

[0014] Preferably, the intermittent feeding mechanism consists of a transmission component and a distribution component. The transmission component is fixedly installed on one side of the transmission mechanism, and the distribution component is rotatably installed on top of the transmission component, extending into the interior of the temporary storage box. The transmission component comprises a mounting base, a worm gear, and a worm wheel. The mounting base is fixedly installed on one side of the side plate, and the worm gear is rotatably installed inside the mounting base. One end of the worm gear is connected to a synchronous pulley via a transmission rod, and a worm wheel is meshed on one side of the worm gear. The distribution component comprises a threaded seat, a threaded sleeve, an adjusting plate, and a receiving plate. The bottom end of the threaded seat is fixedly connected to the top of the worm wheel. The adjusting plate is sleeved on the outside of the threaded seat via a threaded sleeve, and the receiving plate is clamped to the top of the threaded seat via a spline structure.

[0015] Preferably, a lifting door is movably installed on the front of the box, and ropes are suspended on both sides of the lifting door.

The lifting door is moved up and down by the lifting drive mechanism winding the rope.

[0016] Preferably, the detection mechanism consists of a servo motor, a horizontal linear mechanism, a vertical adjustment mechanism, and a camera.

[0017] The beneficial effects of this invention are:

[0018] The technical solution of this invention achieves a fully automated process of intermittent conveying, precise positioning, automatic detection, and release of circuit boards by coordinating the operation of a conveying mechanism with an intermittent feeding mechanism and a positioning mechanism, significantly improving detection efficiency and accuracy. The conveying mechanism synchronously drives the intermittent feeding mechanism to achieve intermittent conveying of circuit boards, transporting them intermittently from the temporary storage box into the main body of the box and smoothly delivering them to the positioning mechanism. The positioning mechanism pauses upon receiving each circuit board to ensure accurate positioning below the detection mechanism, keeping the circuit board in a fixed state during detection and ensuring precise detection. The pause of the positioning mechanism... The function ensures stability during testing, avoiding testing errors caused by circuit board movement, thereby improving testing reliability. After the circuit board is tested, the positioning mechanism releases the circuit board again, and the transmission mechanism releases the tested circuit boards one by one, realizing a fully automated process from temporary storage to testing and release. Through the coordinated work of the transmission mechanism, intermittent feeding mechanism, and positioning mechanism, a fully automated process from intermittent feeding to release is realized. The fully automated process can adapt to the testing needs of circuit boards of different specifications. Moreover, by using the combination of intermittent conveying and intermittent positioning, circuit boards are positioned one by one and released one by one, solving the problems of testing omissions or low efficiency that may be caused by traditional continuous conveying.

Detailed Implementation

[0033] The following will be combined with the appendix Figure 1 To be continued Figure 12 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] A hardware testing device for electronic information engineering includes a housing 1, a transmission mechanism 2, and a positioning mechanism 5. It also includes a testing mechanism 6 fixedly installed on the top wall of the housing 1, and an intermittent feeding mechanism 4 fixedly installed on one side of the transmission mechanism 2. A temporary storage box 3 is fixedly installed on one side of the top of the transmission mechanism 2. The transmission mechanism 2 is installed through the interior of the housing 1. An installation plate 103 is fixedly installed inside the housing 1. The positioning mechanism 5 is installed through the installation plate 103. The transmission mechanism 2 is connected to the intermittent feeding mechanism 4 and the positioning mechanism 5 respectively.

[0035] The intermittent feeding mechanism 4 and the positioning mechanism 5 are driven to operate synchronously by the transmission mechanism 2. The intermittent feeding mechanism 4 separates the circuit boards stored in the temporary storage box 3 in an intermittent manner and transports the separated circuit boards to the component transmission mechanism 2. The transmission mechanism 2 then smoothly transports the circuit boards to the positioning mechanism 5. The positioning mechanism 5 intermittently positions the transported circuit boards to ensure the stability of the circuit boards during testing. It also works with the transmission mechanism 2 to release the tested circuit boards one by one. The process of intermittent material distribution, equidistant conveying, intermittent positioning, and release of circuit boards is completed through the linkage of the transmission mechanism 2 with the intermittent feeding mechanism 4 and the positioning mechanism 5.

[0036] It should be noted that a PLC controller is fixedly installed on one side of housing 1, and the PLC controller has a built-in image of a qualified circuit board. Both sides of the temporary storage box 3 are threaded with through-hole threaded rods. One end of each threaded rod is connected to a movable plate via a turntable. The two movable plates are movably installed on both sides inside the temporary storage box 3. Rotating the threaded rods adjusts the position of the movable plates, allowing for adjustment of the spacing between the two movable plates according to the specifications of the circuit board. The circuit to be tested is placed inside the temporary storage box 3 for temporary storage. The transmission mechanism 2 is then started. The running transmission mechanism 2 synchronously drives the intermittent feeding mechanism 4 and the positioning mechanism 5. The running intermittent feeding mechanism 4 intermittently transports the circuit board from inside the temporary storage box 3 to the transmission mechanism 2, and the running transmission mechanism 2 smoothly transports the circuit board into the housing 1. The circuit board is smoothly delivered to the positioning mechanism 5. Upon receiving each circuit board, the positioning mechanism 5 pauses to accurately position it below the detection mechanism 6, placing it in a fixed state for precise inspection. The detection mechanism 6 then photographs the circuit board and transmits the image information to the PLC controller. Image processing technology is used to analyze and provide feedback on the inspection results. Once the circuit board has been inspected, the positioning mechanism 5 intermittently releases the board, and the conveying mechanism 2 releases the inspected circuit boards one by one. The conveying mechanism 2, in conjunction with the intermittent feeding mechanism 4 and the positioning mechanism 5, achieves a fully automated process from intermittent feeding, conveying, positioning, inspection, and release, effectively improving inspection efficiency and accuracy.

[0037] The intermittent duration of the positioning mechanism 5 is adjusted by changing the rotation speed of the transmission mechanism 2. The dwell time of the circuit board is controlled by the intermittently rotating positioning mechanism 5, thereby adjusting the detection time and ensuring the accuracy of the detection.

[0038] like Figures 3 to 5As shown, the transmission mechanism 2 consists of two side plates 201, a tensioning roller 202, a conveyor belt 203, a drive motor 204, a synchronous pulley 205, a driven transmission toothed roller 206, a driving transmission toothed roller 207, a supplementary light 208, and a guide assembly 209. The two side plates 201 are fixedly installed inside the housing 1. One side plate 201 has an opening at its top, and the guide assembly 209 is installed through one side of the other side plate 201. Multiple driven transmission toothed rollers 206 are rotatably mounted between the two side plates 201 at equal intervals. One end of one driven transmission toothed roller 206 is fixedly mounted with a synchronous pulley 205, which drives the intermittent feeding mechanism 4. The connection is as follows: an active transmission toothed roller 207 is rotatably mounted between the two side plates 201, and the active transmission toothed roller 207 is located below the driven transmission toothed roller 206. A drive motor 204 is fixedly mounted at one end of the active transmission toothed roller 207, and the drive motor 204 is fixedly mounted on one side of the side plate 201. A conveyor belt 203 is mounted around the outside of the multiple driven transmission toothed rollers 206 and the active transmission toothed roller 207, and two tension rollers 202 are rotatably mounted between the two side plates 201, and the two tension rollers 202 are in contact with the conveyor belt 203. A supplementary light 208 is fixedly mounted between the two side plates 201, and the supplementary light 208 is located inside the conveyor belt 203.

[0039] It should be noted that the drive motor 204 is an adjustable speed motor. An adjustable speed motor is a type of motor that changes the motor speed by changing the number of magnetic pole pairs, voltage, current, frequency, etc., so as to achieve higher performance. By adjusting the transmission belt 203, the intermittent positioning time of the positioning mechanism 5, and the intermittent feeding speed of the intermittent feeding mechanism 4 through the drive motor 204, it is convenient to adjust the speed according to the required dwell time for circuit board maintenance.

[0040] The side plate 201 with an opening slot is fixedly connected to the mounting plate 103 to ensure the stability of the mounting plate 103 during installation.

[0041] The tension roller 202 ensures that the conveyor belt 203 is under proper tension by contacting the conveyor belt 203, preventing it from becoming loose or slipping.

[0042] The toothed belt 203 is mounted around the driven toothed roller 206 and the driving toothed roller 207, and the driven toothed roller 206 and the driving toothed roller 207 are engaged with the toothed belt 203.

[0043] When the drive motor 204 drives the active transmission toothed roller 207 to rotate, the active transmission toothed roller 207 drives the meshing transmission toothed belt 203 to rotate, and at the same time drives the positioning mechanism 5 connected by transmission to run.

[0044] Simultaneously, the rotating conveyor belt 203 drives the meshing driven conveyor roller 206 to rotate, while the driven conveyor roller 206 located on one side inside the conveyor belt 203 drives the intermittent feeding mechanism 4 to run through the synchronous pulley 205; the intermittent feeding mechanism 4 intermittently feeds the circuit board onto the conveyor belt 203, and then uses the rotating conveyor belt 203 to uniformly feed the circuit board to the positioning mechanism 5, and the running positioning mechanism 5 receives the circuit board, performs intermittent positioning, and releases it one by one;

[0045] The conveyor belt 203 adopts a hollow design, which facilitates the operation of the supplementary light 208 to provide back illumination for the circuit board on the conveyor belt 203, thereby improving the image clarity during circuit board inspection.

[0046] The guide assembly 209 can adjust the width of the conveying channel according to the specifications of the circuit board to guide the circuit board accurately into the positioning mechanism 5, avoid deviation, and ensure the accuracy of transmission.

[0047] like Figure 4 As shown, the guide assembly 209 consists of an electric push rod and a guide plate. The electric push rod is fixedly installed on one side of the side plate 201, and the guide plate is movably installed on the other side of the side plate 201. The output end of the electric push rod passes through the side plate 201 and is fixedly connected to the guide plate. The position of the guide plate can be adjusted by the electric push rod.

[0048] It should be noted that, according to the circuit board specifications, the electric push rod is powered on and drives the guide plate to move along the direction of the side plate 201. By adjusting the distance between the guide plate and the other side plate 201, the conveying requirements of different circuit board specifications can be adapted. The guide plate is used to guide the circuit board to the positioning mechanism 5. The guide plate and the positioning mechanism 5 work together to realize the circuit board position correction, ensuring that the circuit board is accurately positioned below the detection mechanism 6. This avoids the problem of circuit board detection position deviation affecting the detection accuracy, thereby improving the accuracy and reliability of the detection.

[0049] like Figures 6 to 8 As shown, the positioning mechanism 5 consists of an intermittent limiting component 501, a locking claw 502, an intermittent unlocking component 503, and a transmission bevel gear set 504. The intermittent limiting component 501 is mounted through the mounting plate 103, the locking claw 502 is rotatably mounted on the bottom of the mounting plate 103, and the intermittent unlocking component 503 is rotatably mounted on the bottom of the mounting plate 103. The locking claw 502 is dynamically engaged with the intermittent limiting component 501, and the intermittent unlocking component 503 is dynamically abutting against the locking claw 502. The output end of the transmission bevel gear set 504 is fixed to the bottom of the intermittent unlocking component 503, and the input end of the transmission bevel gear set 504 is fixedly connected to one end of the active transmission toothed roller 207.

[0050] It should be noted that a protrusion is fixedly installed on one side of the locking claw 502; the intermittent limiting component 501 is responsible for controlling a specific position of the mechanical transmission path, causing it to stop at a specific point; the locking claw 502 is rotatably mounted on the mounting plate 103, and can dynamically engage with the intermittent limiting component 501 to achieve intermittent positioning and provide intermittent unlocking; the intermittent unlocking component 503 is also rotatably mounted on the bottom of the mounting plate 103, and it moves in dynamic contact with the locking claw 502, which can move the locking claw 502, thereby unlocking and positioning.

[0051] The output end of the transmission bevel gear set 504 is fixed to the bottom of the intermittent unlocking component 503, receives the transmission from the active transmission toothed roller 207, and transmits power to the intermittent unlocking component 503 through the transmission bevel gear set 504, driving the intermittent unlocking component 503 to rotate. When the intermittent unlocking component 503 rotates to the protrusion on one side of the locking claw 502, it pushes the locking claw 502 to rotate away from the intermittent limiting component 501, so that it moves from the engaging state with the intermittent limiting component 501 to the disengaged state, thereby releasing the positioning restriction on the intermittent limiting component 501. When the locking claw 502 engages with the intermittent limiting component 501 again, the positioning is re-established. By intermittently locking the intermittent limiting component 501, the intermittent limiting component 501 can control the circuit board to stop moving, ensuring the stability of the circuit board during detection.

[0052] like Figures 6 to 7 As shown, the intermittent limiting assembly 501 consists of a rotating disk 5011, a slot disk 5012, and four limiting rubber rods 5013. The rotating disk 5011 is rotatably mounted on the top of the mounting plate 103, and the slot disk 5012 is rotatably mounted on the bottom of the mounting plate 103. The bottom of the rotating disk 5011 is fixedly connected to the slot disk 5012 through a connecting seat. The four limiting rubber rods 5013 are arranged in a ring array on the outside of the rotating disk 5011.

[0053] It should be noted that the intermittent limit component 501 is unlocked and locked by the dynamic engagement between the locking claw 502 and the card slot 5012, thereby achieving the purpose of locking the position of the circuit board and releasing and receiving it one by one.

[0054] When one end of the locking claw 502 is far away from the slot disk 5012, the unlocked state is achieved. The rotating conveyor belt 203 transports the circuit board to the limiting rubber rod 5013 at a constant speed. The circuit board continues to move and pushes the limiting rubber rod 5013 to rotate around the rotating disk 5011, realizing the position change of the four limiting rubber rods 5013. The four positions are alternately changed and the limiting rubber rods 5013 release the circuit board that has been inspected one by one.

[0055] When one end of the locking claw 502 engages with the slot plate 5012, a locking state is achieved, and the two limiting rubber rods 5013 are used to accurately position and limit the circuit board.

[0056] like Figures 7 to 8 As shown, the intermittent unlocking assembly 503 consists of a lifting base 5031, a spring member 5032, and a rotating cam 5033. The lifting base 5031 is fixedly installed on the bottom of the mounting plate 103, and the rotating cam 5033 is rotatably installed on the bottom of the lifting base 5031. One end of the spring member 5032 is installed on one side of the lifting base 5031 by a shaft bolt, and the other end of the spring member 5032 is connected to the locking claw 502 by a shaft bolt.

[0057] It should be noted that the transmission bevel gear set 504 receives the power from the active transmission gear roller 207 and transmits it to the rotating cam 5033, driving the rotating cam 5033 to rotate. The rotating cam 5033 and the locking pawl 502 cooperate to lock and unlock the slot plate 5012. The spring 5032 is used to reset the locking pawl 502 to ensure the locked state.

[0058] The bottom of the rotating cam 5033 is fixedly connected to the output end of the transmission bevel gear set 504. The transmission bevel gear set 504 receives the transmission from the active transmission roller 207 and transmits power to the rotating cam 5033 through the transmission bevel gear set 504, causing the rotating cam 5033 to rotate.

[0059] When the protruding end of the rotating cam 5033 rotates to the protrusion on one side of the locking claw 502, it pushes the locking claw 502 to rotate and move away from the slot disk 5012, thereby releasing the locking of the slot disk 5012. When the locking of the slot disk 5012 is released, the rotating conveyor belt 203 continues to move the circuit board and pushes the limiting rubber rod 5013 to rotate around the rotating disk 5011, so as to realize the release and reception of the circuit boards one by one.

[0060] When the protruding end of the rotating cam 5033 passes the protrusion on one side of the locking claw 502, the elastic tension of the spring 5032 resets the locking claw 502, causing the locking claw 502 to engage with the slot 5012 again, thus achieving intermittent locking of the intermittent limiting component 501. This ensures that the intermittent limiting component 501 fixes the circuit board on the conveyor belt 203 below the detection mechanism 6, ensuring the accuracy of circuit board detection.

[0061] like Figures 9 to 11 As shown, the intermittent feeding mechanism 4 consists of a transmission assembly 401 and a distribution assembly 402. The transmission assembly 401 is fixedly installed on one side of the transmission mechanism 2, and the distribution assembly 402 is rotatably installed on the top of the transmission assembly 401. The distribution assembly 402 extends into the interior of the temporary storage box 3.

[0062] It should be noted that the power transmitted by the synchronous belt pulley 205 is converted into a vertical rotational force by the transmission component 401, which drives the material distribution component 402 to rotate. The material distribution component 402 rotates intermittently into the temporary storage box 3, thereby realizing the intermittent feeding and distribution of circuit boards inside the temporary storage box 3.

[0063] The transmission assembly 401 comprises a mounting base 4011, a worm gear 4012, and a worm wheel 4013. The mounting base 4011 is fixedly mounted on one side of the side plate 201. The worm gear 4012 is rotatably mounted inside the mounting base 4011. One end of the worm gear 4012 is connected to the synchronous pulley 205 via a transmission rod 4014. The worm wheel 4013 is meshed with one side of the worm gear 4012.

[0064] The material distribution assembly 402 consists of a threaded seat 4021, a threaded sleeve 4022, an adjusting plate 4023, and a receiving plate 4024. The bottom end of the threaded seat 4021 is fixedly connected to the top of the worm gear 4013. The adjusting plate 4023 is sleeved on the outside of the threaded seat 4021 through the threaded sleeve 4022. The receiving plate 4024 is sleeved on the top of the threaded seat 4021 through a spline structure.

[0065] It should be noted that the adjusting plate 4023 and the receiving plate 4024 are semi-circular plates, and the receiving plate 4024 is located above the adjusting plate 4023.

[0066] The rotating synchronous pulley 205 transmits power to the worm gear 4012 through the transmission rod 4014. The worm gear 4012 drives the threaded seat 4021 to rotate through the meshing worm wheel 4013. The rotating threaded seat 4021 drives the adjusting plate 4023 and the receiving plate 4024 to rotate simultaneously, so that the adjusting plate 4023 and the receiving plate 4024 rotate alternately into the temporary storage box 3. The upper and lower distributed adjusting plate 4023 and receiving plate 4024 can intermittently feed the circuit boards temporarily stored in the temporary storage box 3.

[0067] like Figure 1 , Figures 2 to 11 As shown, a lifting door 101 is movably installed on the front of the box 1, and a spiral rope 104 is suspended on both sides of the lifting door 101. A lifting drive mechanism 102 is rotatably installed on the top inside the box 1, and one end of the spiral rope 104 is wrapped around the outside of the lifting drive mechanism 102. The lifting door 101 is pulled up and down by the lifting drive mechanism 102 winding the spiral rope 104.

[0068] It should be noted that when the lifting drive mechanism 102 rotates, the winding or releasing of the rope 104 will pull the lifting door 101 up or down, realizing its function of moving up and down in front of the box 1, achieving the purpose of opening and closing; facilitating the maintenance of the internal mechanism of the box 1 by staff.

[0069] like Figure 12As shown, the detection mechanism 6 consists of a servo motor, a horizontal linear mechanism, a vertical adjustment mechanism, and a camera. The servo motor is fixedly installed on the top of the housing 1. The output end of the servo motor is fixedly connected to the horizontal linear mechanism. The output end of the horizontal linear mechanism is fixedly connected to the vertical adjustment mechanism. The camera is fixedly installed on the front of the vertical adjustment mechanism.

[0070] It should be noted that the servo motor is fixedly installed on the top of the housing 1 and provides rotational power through precise control; the horizontal linear mechanism is connected to the output end of the servo motor and can move in the horizontal direction to adjust the detection position; the vertical adjustment mechanism is connected to the output end of the horizontal linear mechanism and can adjust the position in the vertical direction; the servo motor, the horizontal linear mechanism, and the vertical adjustment mechanism are all existing mechanisms, so the specific working principle will not be described in detail.

[0071] The servo motor drives the horizontal linear mechanism to rotate and move, adjusting the camera's orientation. The horizontal linear mechanism moves horizontally, causing the camera to adjust its lateral position, while the vertical adjustment mechanism adjusts the camera vertically. Through the coordinated work of the servo motor, the horizontal linear mechanism, and the vertical adjustment mechanism, the camera's position can be easily adjusted according to the circuit board's specifications, ensuring the camera is precisely centered on the circuit board and at a suitable detection height. This allows the detection mechanism 6 to flexibly adapt to circuit boards of different specifications, achieving precise detection positioning and height adjustment.

[0072] The camera uses a high-definition CCD camera, which automatically scans the circuit board, acquires images, and compares the test points with the qualified parameters in the PLC controller database. After image processing, defects on the target product are detected and displayed on the PLC controller's screen.

[0073] Based on the explanations and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and alterations to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
