Description

Technical Field

[0001] The utility model relates to the technical field of AOI detection devices, in particular to an AOI detection device capable of automatically unloading materials. Background Art

[0002] AOI is the automatic optical identification system, which is the abbreviation of Auto Optical Inspection in English. The full name is automatic optical inspection. It is a device based on optical principles to detect common defects encountered in welding production. It is now widely used in the appearance inspection of circuit board assembly production lines in the electronics industry and replaces the previous manual visual inspection. AOI is a new test technology that has just emerged, but it has developed rapidly. Many manufacturers have launched AOI test equipment. During automatic inspection, the AOI inspection equipment automatically scans PCB products through a high-definition CCD camera, collects images, and compares the test points with the qualified parameters in the database. After image processing, the defects on the target product are checked, and the defects are displayed or marked through a display or automatic mark for maintenance personnel to repair or improve.

[0003] However, when the existing AOI inspection equipment is conducting inspection, the staff usually needs to manually complete the unloading of the inspection materials. During the inspection process, the staff needs to sit in front of the machine and continuously place the inspected materials into the collection box, which is time-consuming and laborious. In addition, when the inspection materials are placed on the conveyor belt on the AOI inspection equipment for transportation, they may be offset or fall from the conveyor belt, and the position of the inspection materials needs to be manually adjusted. If the adjustment is not made in time, the conveyor belt will not be able to accurately transport the inspection materials to the position of the inspection probe, thereby greatly reducing the inspection efficiency and quality of the inspection device.

[0004] Based on this, an AOI inspection device capable of automatic unloading is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] In one embodiment, Figure 1-Figure 7 As shown, an AOI inspection device capable of automatic unloading comprises two support plates 100, a plurality of support legs 101 are provided at the lower ends of the two support plates 100, a limiting assembly 200 is provided at the outer sides of the two support plates 100 for guiding and limiting the inspection material, and a transmission assembly 400 is provided on the opposite side of the two support plates 100 for conveying the inspection material, a bracket 103 is provided at the upper end of the support plate 100, a detection probe 104 is provided at the middle position of the lower end of the bracket 103 for inspecting the inspection material, the detection probe 104 is located above the transmission assembly 400, and a unloading assembly 500 is provided below one end of the support plate 100, and the inspection material after the inspection is completed is automatically unloaded through the unloading assembly 500.

[0029] like Figure 1-Figure 5As shown, the limiting assembly 200 includes two fixed plates 201, and the two fixed plates 201 are detachably arranged at the middle position of the outer side of the two support plates 100 by fixing bolts 203 respectively. An L-shaped rod 202 is inserted on the surface of the fixed plate 201 near the upper end, and a movable plate 204 is fixedly provided at the upper end of the L-shaped rod 202, and a driving assembly 300 is provided at the lower end of the L-shaped rod 202. The L-shaped rod 202 is moved by the driving assembly 300, and then the movable plate 204 is moved. A chamber 205 is opened at one end of the movable plate 204 away from the L-shaped rod 202, and a plurality of limiting rollers 207 are arranged in the chamber 205. The limiting rollers 207 are vertically rotatably arranged in the chamber 205 through the first rotating shaft 206, and the detection material is guided and limited by the plurality of limiting rollers 207 in the chamber 205.

[0030] like Figure 1-Figure 6 As shown, the driving assembly 300 includes a screw 301 and a support plate 303. The screw 301 passes through the two fixed plates 201 and is threadedly connected to the two fixed plates 201. The threads on both sides of the screw 301 turn in opposite directions, and a first bevel gear 302 is fixedly arranged in the middle of the screw 301. Both ends of the support plate 303 are respectively fixedly connected to one end of the two fixed plates 201, and the support plate 303 is located below the transmission assembly 400.

By turning on the first motor 304, the second bevel gear 306 starts to rotate, and the rotation of the second bevel gear 306 drives the first bevel gear 302 to rotate, thereby causing the screw 301 to start rotating. Since the threads on both sides of the screw 301 turn in opposite directions, the rotation of the screw 301 causes the two L-shaped rods 202 to move toward the direction of the test material, thereby causing the movable plate 204 to move toward the direction of the test material until the surface of the limiting roller 207 in the movable plate 204 abuts against the side of the test material.

[0031] like Figure 1-Figure 7As shown, the transmission assembly 400 includes a second motor 401 and two first transmission rollers 402, the second motor 401 is fixedly arranged on the outside of the support plate 100, and the output end of the second motor 401 is fixedly connected to one of the first transmission rollers 402 through a third rotating shaft 404, one end of one of the first transmission rollers 402 away from the second motor 401 is rotationally connected to the support plate 100 through the third rotating shaft 404, and both ends of the other first transmission roller 402 are rotationally connected to the support plate 100 through the third rotating shaft 404, one of the first transmission rollers 402 is transmission-connected to the other first transmission roller 402 through the first conveyor belt 403, and the first transmission roller 402 starts to rotate by turning on the second motor 401, so that the first conveyor belt 403 starts to transmit under the action of the first transmission roller 402.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the unloading assembly 500 includes a bottom plate 501 and a third motor 503, the bottom plate 501 is located below the discharge end of the first conveyor belt 403, and two inclined plates 502 are provided at the upper side of the bottom plate 501, the third motor 503 is fixedly arranged on the outside of one of the inclined plates 502, and a second transmission roller 506 and a third transmission roller 509 are provided on the opposite side of the two inclined plates 502, the second transmission roller 506 and the third transmission roller 509 are both rotatably arranged on the inclined plate 502 through a fourth rotating shaft 504, one end of the second transmission roller 506 is fixedly connected to the output end of the third motor 503 through the fourth rotating shaft 504, the second transmission roller 506 is higher than the third transmission roller 509, and the second transmission roller 506 is The second conveyor belt 505 is connected to the third transmission roller 509 through transmission. The second transmission roller 506 starts to rotate by turning on the third motor 503. Under the action of the second conveyor belt 505, the second transmission roller 506 drives the third transmission roller 509 to rotate. A mounting frame 507 is provided at the upper end of the bottom plate 501. A material receiving box 508 is inserted in the mounting frame 507. The material receiving box 508 can be replaced according to its own needs. The material receiving box 508 is located below the discharge end of the second conveyor belt 505. Under the transportation of the second conveyor belt 505, the detection material moves to the discharge end of the second conveyor belt 505. Since the material receiving box 508 is located below the discharge end of the second conveyor belt 505, the detection material falls into the material receiving box 508, and finally completes automatic unloading.

[0033] like Figure 1-Figure 3 As shown, an anti-slip pad 102 is fixedly provided at the lower end of the support leg 101, so that the detection device is more stable when in use.

[0034] like Figure 4As shown, a rubber pad is provided on the surface of the limiting roller 207, and the rubber pad is used to reduce the friction on the surface of the limiting roller 207, thereby avoiding wear on the detection material and better guiding and limiting the PCB board.

[0035] like Figure 5 As shown, limit blocks 307 are fixedly provided near the ends of both ends of the screw rod 301 to prevent the L-shaped rod 202 from falling off the screw rod 301 when moving.

[0036] The above embodiment discloses an AOI detection device capable of automatic unloading, wherein, when in use, the detection material to be detected is first placed on the first conveyor belt 403, and then the second bevel gear 306 starts to rotate by turning on the first motor 304. Since the second bevel gear 306 and the first bevel gear 302 are meshed with each other, the rotation of the second bevel gear 306 drives the first bevel gear 302 to rotate, thereby causing the screw 301 to start rotating. Since the threads on both sides of the screw 301 turn in opposite directions, the rotation of the screw 301 causes the two L-shaped rods 202 to move toward the detection material, thereby causing the movable plate 204 to move toward the detection material. When the surface of the limiting roller 207 in the movable plate 204 abuts against the side of the detection material, the first motor 304 is turned off, and then the second motor 401 is turned on to cause the first transmission roller 402 to start rotating, thereby causing the first conveyor belt 403 to start transmission under the action of the first transmission roller 402, thereby realizing the transportation of the detection material. When the detection material on the first conveyor belt 403 moves to the bottom of the bracket 103, the detection probe on the bracket 103 The head 104 can detect the test material, and when the test material is conveyed, the limit roller 207 can guide and limit the test material, so that the test material is always in the middle position of the first conveyor belt 403, avoiding the test material from being offset or falling from the first conveyor belt 403 during transportation. At the same time, it can also ensure that when the test material moves to the bottom of the bracket 103, it is directly below the detection probe 104, so as to better detect the test material, thereby improving the detection efficiency and quality of the detection device. In addition, after the detection is completed, the second transmission roller 506 starts to rotate by turning on the third motor 503. Under the action of the second conveyor belt 505, the second transmission roller 506 drives the third transmission roller 509 to rotate. When the test material that has completed the inspection moves to the discharge end of the first conveyor belt 403, under the action of gravity, the test material falls onto the second conveyor belt 505, and then under the transportation of the second conveyor belt 505, the test material falls into the receiving box 508, thereby completing automatic unloading.

[0037] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
