Without more limitations, the element defined by the sentence "comprises a" does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0038] In this application, the term "and / or" is a description of the association relationship between the associated objects, which means that there can be three kinds of relationships. For example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in the application generally represents a "and / or" relationship between the front and rear associated objects.

[0039] In this application, the terms "connected", "coupled", "engage", "engagement", "mounting" can be direct connection, coupling or mounting, or indirect connection, coupling or mounting through an intermediate part. For example, direct connection refers to two parts or components connected together without an intermediate part, and indirect connection refers to two parts or components connected to at least one intermediate part, and the two parts or components are connected through the intermediate part. In addition, "connection" and "coupling" are not limited to physical or mechanical connection or coupling, and can include electrical connection or coupling.

[0040] In this application, those of ordinary skill in the art will understand that the relative terms used in connection with quantities or conditions (for example, "about", "approximately", "substantially" and the like) include the values described and have the meaning indicated by the context. For example, the relative terms at least include the degree of error related to the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. related to a specific value. Such terms should also be considered to disclose the range defined by the absolute values of the two endpoints. The relative terms can refer to the indicated value plus or minus a certain percentage (for example, 1%, 5%, 10% or more). The numerical value without the relative term should also be disclosed as a specific value with a tolerance. In addition, "substantially" when expressing the relative angular positional relationship (for example, substantially parallel, substantially perpendicular), can refer to plus or minus a certain degree (for example, 1 degree, 5 degrees, 10 degrees or more) based on the indicated angle.

[0041] In this application, those of ordinary skill in the art will understand that the functions performed by the components can be performed by one component, multiple components, one part, or multiple parts.

For example, the lower side can include the lower side, the lower left side, the lower right side, the lower front side and the lower back side, etc.

[0043] At present, most 3C production and manufacturing enterprises adopt manual quality inspection in the industrial production quality inspection link, and some production enterprises use mechanical measuring instruments, optical instruments or sensors and other automatic equipment to detect the size, weight and shape of parts. In the existing workpiece detection method, manual quality inspection has the following disadvantages: 1. Low efficiency: difficult to meet the demand of mass production; 2. Poor consistency: manual quality inspection is easily affected by fatigue, personal experience, etc., and the standards are not the same, which affects the consistency of detection; 3. Easy to make mistakes: due to vision and attention, etc., small defects are easily missed or misjudged. The automatic detection equipment has the following disadvantages: 1. Poor adaptability: traditional automatic detection equipment is mostly hardware driven, with poor adaptability, which is difficult to meet the characteristics of fast iteration of 3C products; 2. High initial investment: high equipment purchase, installation and maintenance cost, especially for high-precision equipment; 3. Lack of intelligence: difficult to handle complex detection tasks or abnormal situations, and cannot replace part of the manual detection work.

Specifically, the small assembly detection system further includes a display, which is in communication connection with the vision mechanism 300. The defect type and defect coordinates output by the intelligent detection component can be output to the display for confirmation by an operator. Specifically, the display is fixed to the machine table shell 500. It should be noted that the intelligent detection component is a relatively mature technology in the prior art, and therefore its structure and operating principle will not be listed one by one here.

[0050] In the embodiment, referring to Figure 2 、 Figure 3 and Figure 5 , the vision mechanism 300 further includes a camera fixing frame 320, which includes a first horizontal rod, a first vertical rod, and a second vertical rod.

If the workpiece 1 is a good product, the operator can control the turntable 210 to drive the workpiece 1 to rotate to the first station, and the operator manually takes down the workpiece 1 and puts it into the second storage tray.

[0053] In this embodiment, referring to Figure 6 The blanking mechanism 400 further includes a clamping piece and a mechanical arm fixing frame 430. The mechanical arm fixing frame 430 includes a second horizontal rod, a third vertical rod and a fourth vertical rod. The second horizontal rod is fixed to the end face of the machine main body 100, the third vertical rod is slidably arranged on the second horizontal rod in the horizontal direction, the fourth vertical rod is slidably arranged on the third vertical rod in the vertical direction, and the clamping piece is arranged on the fourth vertical rod. Specifically, the clamping piece is arranged as a clamping jaw. It should be noted that the clamping jaw clamping the workpiece 1 is a very mature technology in the prior art, and the structure and principle thereof will not be described here. Specifically, the second horizontal rod and the third vertical rod are both provided with sliding rails, and the third vertical rod and the fourth vertical rod are both provided with sliding blocks.

Specifically, the control mechanism comprises a light source controller to adjust the brightness of the light source assembly.

[0056] In use, the small assembly detection system provided in the embodiment, the operator places the first workpiece 1 into the fixing assembly 220 on the first station, presses the start button with both hands, and then the turntable 210 drives the first workpiece 1 to the second station. The operator presses the start button with both hands again, and then the turntable 210 randomly selects two angles on the periphery of the second station and controls the first camera module 310 to take front images of the first workpiece 1 at the two angles. After the shooting is completed, the turntable 210 drives the first workpiece 1 back to the second station. At this time, the operator places the second workpiece 1 into the fixing assembly 220 on the first station, presses the start button with both hands, and then the turntable 210 drives the first workpiece 1 to the third station and drives the second workpiece 1 to the second station. The operator presses the start button with both hands again, and then the turntable 210 randomly selects two angles on the periphery of the second station and controls the first camera module 310 to take front images of the second workpiece 1 at the two angles. The turntable 210 randomly selects two angles on the periphery of the third station and controls the second camera module to take back images of the first workpiece 1 at the two angles. The intelligent detection assembly judges whether the first workpiece 1 is defective and inputs the result to the display screen. The operator presses the button with both hands according to the display result to control the turntable 210 to drive the first workpiece 1 to be unloaded at the fourth station or the first station. After the unloading is completed, the turntable 210 drives the second workpiece 1 back to the second station. The operator places the third workpiece 1 into the fixing assembly 220 on the first station, and the cycle is repeated in this way.

[0057] Specifically, several images need to be collected at each station, which needs to be set according to the length and other information of the workpiece 1. If the entire product can be completely photographed by one imaging, then one imaging is enough. If the complete image of the workpiece 1 cannot be photographed by one imaging, then multiple imaging is needed to complete. The number of imaging and the imaging angle can be set on the PLC system.
