[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0034] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0035] like Figures 1 to 11As shown, the present invention provides an electronic component inspection device based on visual recognition, comprising: a machine base 1, on which a rotating disk 2 is rotatably mounted, and on which a power assembly 3 is mounted to drive its rotation. The power assembly 3 is preferably a pneumatic slip ring assembly, which has high precision and is easy to control. Along the rotating disk 2, there are sequentially arranged a loading station, a laser station, a visual inspection station, and a unloading station. The loading station is used for loading, the laser station is used for laser engraving, the visual inspection station is used for visual inspection, and the unloading station is used for unloading.

[0036] This utility model has two loading and unloading methods: one is manual loading and unloading, and the other is automatic loading and unloading. The manual loading and unloading will not be described in detail. In the automatic loading and unloading, the loading and unloading are carried out by a robot arm 4. The robot arm 4 is a four-axis robot arm. The robot arm 4 transports the material to the conveyor line 5. The conveyor line 5 is a bidirectional belt conveyor, that is, loading is carried out on one side and unloading is carried out on the other side.

[0037] The rotating disk 2 is equipped with a fixture 6, which includes a fixed plate 7, a movable pusher 8, and a fixing pin 9 fixedly installed on the fixed plate 7. It should be noted that the fixing pin 9 is fixedly installed on side a and side b, and the movable pusher 8 is located on side c and side d. In particular, there are two movable pushers 8 on side d.

[0038] It should be noted here that when fixing the electronic component, the electronic component is first brought into contact with the fixing pin 9, then the movable pusher 8 on side c is brought into contact with the electronic component, and then the two movable pushers 8 on side d are brought into contact with the electronic component.

[0039] The activity promotion 8 includes a fixed base 10 fixedly installed on the fixed plate 7, a spring 11 fixedly connected to the fixed base 10 at one end, and a movable block 12. The movable block 12 abuts against the spring 11. The movable block 12 is equipped with an adjusting rod 13, which is detachably connected to the movable block 12 and adjusts the compression degree of the spring 11.

[0040] It should be explained here that the adjusting rod 13 is a set screw, which is threadedly connected to the movable block 12. By adjusting the depth to which the set screw is screwed into the movable block 12, the compression degree of the spring 11 is adjusted, thereby changing the elastic force of the spring 11. The elastic force of the spring 11 can be adjusted within the range of 0.28N to 2.23N.

[0041] Magnetic components are fixedly installed on the fixing plate 7. There are four magnetic components. It is important to emphasize that the magnetic components are columnar magnets, which are fixedly installed in the external threaded fastener. The external threaded fastener can be a bolt with a hole drilled in the middle. The electronic product is fixed from below by the magnet.

[0042] At the loading station and the unloading station, a fixture opening mechanism is provided. The fixture opening mechanism includes a push cylinder 15 and a push rod 16 connected to the piston rod of the push cylinder 15. The push cylinder 15 drives the push rod 16 to move the movable pusher 8 along the axial direction of the spring 11.

[0043] It should be added here that the opening mechanism of the fixture 6 is provided in two sets, one set opens the movable pusher 8 at side c, and the other set opens the movable pusher 8 at side d. Since their basic principles are the same, only the specific shape of the push rod 16 is adapted, and this application describes them together.

[0044] At the laser station, a first linear module 17 is installed on the machine base 1, and a laser head 18 is installed on the moving part of the first linear module 17.

[0045] At the visual inspection station, a first camera 19 is installed on the machine 1, and a lens can be installed on the first camera 19 as needed.

[0046] The transport line 5 is provided with a second linear module 20 on its side. The second linear module 20 is equipped with a second camera 21 and a scanning dock 22, which is used to scan QR codes.

[0047] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
