Description

Technical Field

[0001] This invention relates to the field of electronic component retail technology, specifically to a quality inspection device for electronic component retail. Background Technology

[0002] With the continuous development of the electronics industry, the market circulation of various electronic components is constantly increasing. The retail sector has put forward higher requirements for the quality control of components. Electronic component quality testing equipment has become a key device for screening defective products and ensuring the quality of goods in the retail scenario. Therefore, a dedicated electronic component retail quality testing device is needed to complete the batch testing work.

[0003] However, existing quality inspection devices only use simple single-sided or two-way clamping structures during use, which makes it difficult to achieve multi-directional wrap-around limiting. The clamping stability of electronic components is poor, and they are prone to displacement and shaking during inspection, which seriously reduces the stability of the inspection process. Summary of the Invention

[0006] The multi-directional wrapping and fixing method ensures that the components are firmly clamped, making it less likely for them to shift or shake during processing and testing, thus improving the stability of the testing.

[0007] Preferably, the drive unit includes a guide assembly and a power assembly; The guide assembly is located on top of the base, and the power assembly is located on the guide assembly.

[0008] Preferably, the guide assembly includes two grooved plates and a guide rod; Both of the aforementioned grooved plates are disposed on the top of the base, and the guide rod is fixedly connected between the two grooved plates. The guide rod passes through the two support plates and is slidably connected to the two support plates.

[0009] Preferably, the power assembly includes a bidirectional threaded rod, a motor, and protective components; The bidirectional threaded rod passes through two slotted plates and is rotatably connected to the two slotted plates. The bidirectional threaded rod passes through two support plates and is threadedly connected to the two support plates. The first motor is fixedly connected to the slotted plate on the left side, and the output shaft of the first motor is fixedly connected to the bidirectional threaded rod through a coupling. The protective component includes several telescopic protective sleeves; Several of the telescopic protective sleeves are fitted onto a bidirectional threaded rod. The two telescopic protective sleeves located on the left and right sides, with their sides far apart from each other, are fixedly connected to two grooved plates, respectively. The two telescopic protective sleeves located on the left and right sides, with their sides close to each other, are fixedly connected to two support plates, respectively. The telescopic protective sleeve located in the middle is fixedly connected to two support plates on its left and right sides, respectively.

[0010] The telescopic protective sleeve can extend and deform synchronously with the clamping action, covering the threaded rod throughout the process and preventing dust, debris, and oil from adhering to the surface of the bidirectional threaded rod. The synchronous drive improves the fixing efficiency and stability.

[0011] Preferably, the rotating part includes a rotating component and a supporting component; The rotating component is mounted on the base, and the supporting component is mounted on the rotating component.

[0012] Preferably, the rotating assembly includes two trapezoidal support plates, two rotating shafts, and a second motor; Both trapezoidal support plates are fixedly connected to the top of the base. The two rotating shafts pass through the two trapezoidal support plates respectively and are rotatably connected to the two trapezoidal support plates respectively.

[0014] The inspection orientation can be adjusted directly without disassembling the workpiece, simplifying the inspection process and improving inspection efficiency.

[0015] Preferably, the detection head in this device uses a Panasonic SV-035C image sensor. Its working principle is to acquire the surface image of electronic components through an optical lens, convert the light signal into an electrical signal and transmit it to the processing unit. The internal algorithm analyzes and compares the image features to identify component appearance defects, size deviations and marking abnormalities, and completes quality inspection.

[0016] The present invention has the following beneficial effects: (1) By setting a fixing part, the two support plates are driven by the slide rod to move the L-shaped silicone fixing plate towards each other and fit the left and right sides of the electronic component. When the support plates continue to approach, they slide along the slide rod to compress the spring and store energy. The bidirectional hinge block moves away from the support plate. Relying on the hinge transmission of the bidirectional hinge block, hinge rod and slider, the slider is pulled to slide towards each other in the limiting groove. The slider drives the silicone fixing plate to approach the front and back sides of the component to complete the clamping. With the help of the L-shaped silicone fixing plates on both sides, the component is wrapped and limited in all directions. The multi-directional wrapping and fixing method makes the component firmly clamped and it is not easy to shift or shake during the processing and testing process, thus improving the stability of the test. (2) By setting up a driving unit, the electronic components are placed between two sets of L-shaped silicone fixing plates during use. The motor is started to drive the bidirectional threaded rod to rotate. Relying on the parallel guiding cooperation between the bidirectional threaded rod and the guide rod, the two support plates are driven to move towards each other to clamp the workpiece. The three sets of telescopic protective sleeves that are matched at the same time adapt to the displacement of the support plates and continuously wrap and protect the bidirectional threaded rod. The telescopic protective sleeves can expand and contract synchronously with the clamping action, covering the threaded rod throughout the process and preventing dust, debris and oil stains from adhering to the surface of the bidirectional threaded rod. The synchronous drive improves the fixing efficiency and stability. (3) By setting up a rotating part, if it is necessary to switch the detection surface of electronic components, the motor is started to drive the rotating shaft to rotate the slotted plate. The slotted plate is linked with the guide rod and the bidirectional threaded rod to rotate synchronously with the other slotted plate and the matching rotating shaft. The two slotted plates drive the support ring to slide around the annular groove in a circumferential limit, thereby stabilizing the overall rotation of the slotted plate. The guide rod and the bidirectional threaded rod synchronously drive the support plate together with the clamped and fixed electronic components to rotate in a circumferential manner, thereby completing the switching and adjustment of the detection position of the components. The detection orientation can be directly adjusted without disassembling the workpiece, simplifying the detection process and improving the efficiency of the detection operation.

The output shaft of motor 413 is fixedly connected to the trapezoidal support plate 411 on the left side and the output shaft of motor 413 is fixedly connected to the rotating shaft 412 on the left side through a coupling. The support assembly 42 includes two support rings 421 and two annular grooves 422. The two support rings 421 are respectively sleeved on the two rotating shafts 412.

[0024] It should be noted that the detection head 113, motor 1 322 and motor 2 413 in this application can all be automatically controlled by using a program set in the control panel and inputting relevant parameters as needed. This control method can be achieved using existing technologies, such as PLC.

[0025] One specific application of this embodiment is as follows: When in use, electronic components are placed between two L-shaped silicone fixing plates 221, and motor 322 is started. Motor 322 drives the bidirectional threaded rod 321 to rotate. Under the action of the bidirectional threaded rod 321 and the guide rod 312 in parallel cooperation, the bidirectional threaded rod 321 drives the two support plates 211 to move closer to each other. During this process, the three telescopic protective sleeves 323 deform as the two support plates 211 move, thereby protecting the bidirectional threaded rod 321. Two support plates 211, via two sliding rods 212, drive two L-shaped silicone fixing plates 221 closer together, contacting the left and right sides of the electronic components. Then, the two support plates 211 continue to move closer together, sliding on the two sliding rods 212 and compressing the two springs 217, causing them to deform and generate elastic force. During this process, two bidirectional hinge blocks 215 move away from the two support plates 211. Since the bidirectional hinge blocks 215 are hinged to the two hinge rods 216, and the two... Each hinge rod 216 is hinged to two sliders 214 respectively. Therefore, the two bidirectional hinge blocks 215 pull the corresponding sliders 214 in the corresponding limiting grooves 213 through the corresponding two hinge rods 216 and move closer to each other. The four sliders 214 respectively drive the corresponding silicone fixing plates 222 to move closer to the front and rear of the electronic components and fix the electronic components on the front and rear. By fixing and cooperating with the left and right sides of the two L-shaped silicone fixing plates 221, the electronic components are fixed in a multi-directional wrapping manner. After fixing, the detection head 113 is activated. The detection head 113 acquires the surface image of the electronic component through the optical lens, converts the light signal into an electrical signal and transmits it to the processing unit. The internal algorithm analyzes and compares the image features to identify the component's appearance defects, size deviations and marking abnormalities, and completes the quality inspection. When it is necessary to adjust the detection surface of the electronic component, start motor 413. Motor 413 drives the corresponding rotating shaft 412 to rotate. The rotating shaft 412 drives the corresponding slotted plate 311 to rotate. The slotted plate 311 drives the other slotted plate 311 to rotate through the guide rod 312 and the bidirectional threaded rod 321. The other slotted plate 311 drives the corresponding rotating shaft 412 to rotate. At this time, the two slotted plates 311 respectively drive the two support rings 421 to move in the corresponding annular groove 422 and perform circular motion with the trajectory of the annular groove 422, thereby smoothly driving the two slotted plates 311 to rotate. The guide rod 312 and the bidirectional threaded rod 321 drive the two support plates 211 to perform circular motion, thereby driving the fixed electronic component to perform circular motion, thereby adjusting the detection surface of the electronic component.
