Description

Technical Field

[0001] This utility model relates to the field of power supply board testing technology, specifically a quality testing device for power supply board production. Background Technology

[0002] A power supply board is a circuit board used to provide power support. It is commonly found in electronic devices. A power supply board can convert the input AC power into the DC power required by the device and provide stable voltage and current output to meet the power supply needs of different electronic components.

[0003] A search revealed that the announcement number is CN221811837U, and the name is "PCB Board Inspection Device". It includes a base, a bracket, a transmission mechanism, a connecting plate, and an inspection mechanism. Through research and analysis, it was found that this device effectively avoids the problem of PCB board damage caused by excessive manual pressure by setting a sensor on one side of the inspection board and controlling the pushing force of the push rod by a hydraulic cylinder. However, it still has the following disadvantages to a certain extent.

[0004] For example, if the device does not have an automatic feeding function and only requires manual feeding, and only one product can be tested at a time, the entire operation requires frequent manual loading and unloading, which is very inconvenient. Manual placement can easily lead to uneven product placement, which can cause deviations in the test results. In order to solve the above technical problems, we have designed a quality inspection device for power board production. Utility Model Content

[0005] The purpose of this utility model is to provide a quality inspection device for power supply board production, which has the advantages of convenient material loading and rejection of unqualified products. It solves the problems of manual material loading, which can only be inspected one product at a time, and the overall operation requires frequent manual loading and unloading, which is very inconvenient. Manual placement can easily lead to uneven product placement and deviations in the inspection results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quality inspection device for power supply board production, comprising a mounting plate, with conveyor rollers rotatably mounted on both the left and right sides of the front side of the mounting plate via bearings, a conveyor belt drivingly connected to the surface of the conveyor rollers, a motor fixedly mounted on the left side of the back surface of the mounting plate, the output shaft of the motor fixedly connected to the left conveyor roller, a support plate fixedly connected to the left side of the top of the mounting plate, a feeding assembly fixedly connected to the front side of the support plate, the feeding assembly comprising a material shell, the material shell fixedly mounted on the front side of the support plate, a board body disposed at the bottom of the inner cavity of the material shell, an electric push rod fixedly connected to the bottom of both the front and rear sides of the material shell, a pusher plate fixedly connected to the telescopic end of the electric push rod, and a rubber ball fixedly connected to the right side of the bottom of the material shell. A time controller is fixedly installed on the front surface of the material shell. A detection component is fixedly installed on the rear side of the top of the mounting plate.

A detection contact is fixedly installed at the bottom of the detection pressure plate. A mounting frame two is fixedly installed on the left side of the top of the detection pressure plate. An infrared detector one is fixedly installed at the bottom of the mounting frame two. A material pushing component is fixedly installed on the top of the mounting plate. The material pushing component includes an electric push rod three, which is installed through the right side of the mounting plate. A material pushing frame is fixedly connected to the telescopic end of the electric push rod three. An infrared detector two is embedded in the rear side of the inner cavity of the material pushing frame.

[0007] Preferably, the distance between the bottom of the material shell and the conveyor belt is equal to the thickness of the main body of the plate, and both the top and bottom of the material shell are open.

[0008] Preferably, the material shell has movable grooves on both the left and right sides, and a foam cover plate is provided on the top of the inner cavity of the material shell. The two ends of the foam cover plate extend to the movable grooves on both sides and slide in contact with their inner walls.

[0012] Preferably, a guide frame is fixedly installed on the right side of the top of the mounting plate and in front of the pusher, with the top of the guide frame close to the conveyor belt and flush with its top.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses a material shell to place the product, and a foam cover to shield the product and prevent dust from falling onto the product surface. The product at the bottom of the material shell is blocked by rubber balls, preventing it from being pushed by the conveyor belt. An electric push rod drives a pusher plate to push the product at regular intervals, allowing it to pass through the rubber balls and be conveyed. This effectively ensures that the product is discharged in an orderly manner, achieving a uniform automatic feeding effect. In conjunction with a detection component, the product is detected. When a product fails the test, an electric push rod drives a pusher frame to push the defective product into the guide frame for discharge and collection, achieving the effect of automatically rejecting defective products and saving manual operation time.

[0024] Please see Figures 1-8A quality inspection device for power board production includes a mounting plate 1. Conveyor rollers 2 are rotatably mounted on the left and right sides of the front side of the mounting plate 1 via bearings. A conveyor belt 8 is connected to the surface of the conveyor rollers 2. A motor 3 is fixedly mounted on the left side of the back surface of the mounting plate 1, and the output shaft of the motor 3 is fixedly connected to the left side of the conveyor roller 2. A support plate 11 is fixedly connected to the top left side of the mounting plate 1. By setting the support plate 11, a material shell 51 can be installed and fixed to prevent it from shaking during operation. A feeding assembly 5 is fixedly connected to the front side of the support plate 11. The feeding assembly 5 includes a material shell 51, which is fixedly mounted on the front side of the support plate 11. A board body 55 is provided at the bottom of the inner cavity of the material shell 51. The front and rear sides of the material shell 51... Electric push rods 56 are fixedly connected to the bottom of each side. A pusher plate 52 is fixedly connected to the telescopic end of the electric push rod 56. The pusher plate 52 pushes the main body 55, allowing it to move onto the conveyor belt 8 for transport. A rubber ball 58 is fixedly connected to the right side of the bottom of the material shell 51. The rubber ball 58 blocks the main body 55, preventing it from moving to the right during conveyor belt 8 transport; it can only pass through by being pushed by the pusher plate 52. This allows the electric push rods 56 to drive the pusher plate 52 for intermittent feeding, unaffected by the conveyor belt 8. A timer 10 is fixedly installed on the front surface of the material shell 51. The timer 10 allows for regular feeding. The electric push rod 56 is controlled to work intermittently, pushing the pusher plate 52 to feed material. A detection component 6 is fixedly installed on the rear side of the top of the mounting plate 1. The detection component 6 includes a mounting bracket 61, which is fixedly installed at the center of the rear side of the top of the mounting plate 1. An electric push rod 63 is installed through the front side of the top of the mounting bracket 61. A detection pressure plate 64 is fixedly installed at the telescopic end of the electric push rod 63. A detection contact 65 is fixedly installed at the bottom of the detection pressure plate 64. A mounting bracket 62 is fixedly installed on the left side of the top of the detection pressure plate 64. An infrared detector 66 is fixedly installed at the bottom of the mounting bracket 62. By setting the infrared detector 66, the position of the main body 55 of the board can be detected and its movement can be controlled. After moving downwards, a signal can be transmitted, which causes the electric push rod 63 to push the detection plate 64 and the detection contact 65 to detect the board body 55, achieving an automatic detection effect. The top of the mounting plate 1 is fixedly installed with a pusher assembly 4, which includes an electric push rod 41. The electric push rod 41 is installed through the right side of the mounting plate 1. The telescopic end of the electric push rod 41 is fixedly connected to a pusher frame 42. An infrared detector 43 is embedded in the rear side of the inner cavity of the pusher frame 42. By setting the infrared detector 43, the position of the board body 55 can be detected, and after it moves downwards, a signal can be transmitted, which controls the electric push rod 41 to push the pusher frame 42 to move, pushing the board body 55 into the guide frame 7.

[0025] Please see Figure 1 and Figure 2 The distance between the bottom of the material shell 51 and the conveyor belt 8 is the thickness of the board body 55. This design can prevent only one board body 55 from passing under the material shell 51, so as to achieve the effect of transferring one product at a time. The top and bottom of the material shell 51 are open.

[0026] Please see Figure 4 and Figure 8 The left and right sides of the shell 51 are provided with moving grooves 53. The moving grooves 53 can limit the foam cover plate 54 so that it can move downward with the main body of the board 55. The top of the inner cavity of the shell 51 is provided with a foam cover plate 54. The two ends of the foam cover plate 54 extend to the moving grooves 53 on both sides and slide in contact with their inner walls. The foam cover plate 54 can cover the main body of the board 55 so that dust will not stick to it, thus achieving the effect of dust protection for the main body of the board 55.

[0027] Please see Figure 1 , Figure 2 and Figure 4 The surface of the electric push rod 56 is provided with a fixing sleeve 57. The electric push rod 56 is fixedly connected to the surface of the material shell 51 through the fixing sleeve 57. By setting the fixing sleeve 57, the electric push rod 56 can be installed and fixed so that it will not shake during operation.

[0028] Please see Figure 1 , Figure 2 and Figure 4 The top and bottom of the pusher plate 52 are in sliding contact with the bottom of the material shell 51 and the top of the conveyor belt 8, respectively. The thickness of the pusher plate 52 is the same as the thickness of the board body 55.

[0029] Please see Figure 1 , Figure 2 and Figure 3 Limiting baffles 9 are fixedly installed on the top of the mounting plate 1 and on both the front and rear sides of the conveyor belt 8. The distance between the bottom of the limiting baffle 9 and the conveyor belt 8 is less than the thickness of the plate body 55, and the limiting baffle 9 does not contact the conveyor belt 8.

[0030] Please see Figure 1 and Figure 2 A guide frame 7 is fixedly installed on the right side of the top of the mounting plate 1 and in front of the pusher frame 42. The top of the guide frame 7 is close to the conveyor belt 8 and is flush with its top.

[0031] In use, the main body 55 of the circuit board is placed inside the housing 51, and then a foam cover 54 is placed on top of the main body 55 to block dust. The motor 3 is started, driving the conveyor roller 2 to rotate slowly, thereby causing the conveyor belt 8 to move to the right. The main body 55 at the bottom of the housing 51 is blocked by the rubber ball 58 and will not move to the right. The time controller 10 controls the electric push rod 56 to work periodically, causing it to drive the pusher plate 52 to push the bottommost main body 55 at regular intervals. At this time, the rubber ball 58 on the right side deforms due to compression, allowing the main body 55 to pass to the right. When the pusher plate 52 returns to its original position, the rubber ball 58 returns to its original position again, until the electric push rod 56 drives the pusher plate 52 to push another main body 55, and this process is repeated. To achieve uniform material feeding, when the infrared detector 66 detects a product, it sends a signal to the time controller 10. The time controller 10 then controls the extension of the electric push rod 63, causing it to lower the detection plate 64 until the detection contact 65 contacts the top detection end of the main body 55. At this point, the electric push rod 63 quickly resets. When the detection contact 65 detects a qualified product, it is directly conveyed to the right by the conveyor belt 8 to the finished product area. When the product fails to pass the test, it sends a signal to the time controller 10, causing it to control the electric push rod 41. When the infrared detector 43 in front of the electric push rod 41 detects a product, the electric push rod 41 quickly extends, causing it to push the pusher 42 forward to the guide frame 7, where it is guided to the defective area for repair.

[0032] In summary, this quality inspection device for power board production, through the cooperation of mounting plate 1, conveyor roller 2, motor 3, pushing component 4, feeding component 5, inspection component 6, conveyor belt 8 and time controller 10, solves the problems of manual feeding alone, where only one product can be inspected at a time, the overall operation requires frequent manual loading and unloading, which is very inconvenient, and manual placement is prone to uneven product placement, which can easily lead to deviations in inspection results.
