Technical Field

[0002] During the manufacturing process for aluminum cases for mobile phones and computers, the raw aluminum alloy undergoes CNC machine processing, including cutting, milling, and drilling, to achieve precise shapes and specifications. However, after these processing steps, rigorous inspection of the aluminum case's dimensions and appearance is crucial. Dimensional inaccuracies can lead to mismatches during subsequent processing and assembly, compromising the product's overall aesthetics and practicality.

[0014] The above-mentioned aluminum shell detection device is used, and the method of use includes the following steps: S1. Start the feeding component: Start the third motor, and drive the sliding sleeve in the sliding rail frame through the first driving rod and the second driving rod. The lifting block in the sliding sleeve, under the action of the second spring, pushes the aluminum shell on the placement rack along the inclined plate to the detection plate; When the aluminum shell is pushed onto the detection plate, the first motor and the second motor are started, the first threaded screw and the second threaded screw rotate, driving the first slider and the second slider to move in the slide groove, and the first positioning block and the second positioning block on the first slider and the second slider perform preliminary positioning on the aluminum shell. The first positioning block pushes the second clamping block to move toward the first clamping block through the first spring, further clamping the aluminum shell to ensure its stability during the detection process; S2: Weight detection: After the aluminum shell is placed on the detection plate, the weight is transferred to the first connecting rod and the second connecting rod through the weighing plate. The first connecting rod and the second connecting rod act through the lever action of the first cross bar, the second cross bar, the third cross bar, the first vertical rod and the second vertical rod, so that the first pointer indicates the weight of the aluminum shell on the first measuring disk; S3: Dimension detection: After the aluminum shell is stably positioned, the dimension detection component starts working. The first moving block above the second clamping block drives the third and fourth transmission rods to move through the transmission of the first and second transmission rods. The movement of the third and fourth transmission rods causes the second moving block to move on the amplification mechanism. S4: Reading dimensional data: The second moving block slides in the moving grooves on the first measuring block and the second measuring block of the amplifying mechanism and points out the data through the second pointer. Through the amplification effect of the amplifying mechanism, the dimensional data of the aluminum shell can be read, and the data detected by the weight detection component and the size detection component are recorded to determine whether the aluminum shell is qualified or to perform further processing on the aluminum shell according to the data; S5: After the inspection is completed, the aluminum shell is taken out. Under the action of the counterweight, the first pointer moves downward and touches the metal iron sheet to close the circuit. The third motor is energized and started, and the steps in S are repeated. That is, the sliding sleeve slides in the sliding rail frame through the transmission of the first driving rod and the second driving rod. The ejecting block in the sliding sleeve pushes the next aluminum shell on the placement rack along the inclined plate to the inspection plate under the action of the second spring, and the inspection work is continued. At this time, the weight of the aluminum shell will cause the first pointer to move upward, thereby separating from the metal iron sheet, disconnecting the closed circuit and stopping the third motor, avoiding unnecessary feeding actions, and ensuring that only one aluminum shell is pushed to the inspection plate in each inspection cycle.
[0015] The beneficial effects of the present invention are: 1. The present invention realizes the automatic pushing of the aluminum shell from the placement rack to the detection plate through the coordinated action of the third motor, the first driving rod and the second driving rod in the feeding component. This design reduces the tedious steps of manual feeding and improves the detection efficiency. The start and stop of the third motor are controlled by the closing / disconnection of the metal iron sheet and the circuit, thereby realizing the precise control of the feeding action. This design not only improves the detection efficiency, but also avoids the confusion and errors caused by excessive feeding.
[0016] 2. The detection process of the weight detection component and the size detection component in the present invention is coherent. Once the aluminum shell is pushed onto the detection plate, the weight and size dual detection can be carried out simultaneously without the need for intermediate transfer, further improving the detection speed; The weight detection component utilizes the principle of leverage and a mechanical transmission structure to maintain stability while weighing. This mechanical transmission structure accurately measures the weight of the aluminum shell, providing reliable data for quality control. The size detection component achieves precise measurement of the aluminum shell's dimensions through the combination of a transmission rod and an amplification mechanism. The design of the amplification mechanism makes reading data more intuitive.
[0017] 3. The present invention ensures the stability of the aluminum shell during testing by initially positioning the first and second positioning blocks in the positioning mechanism, and further clamping the first and second clamping blocks via springs, thereby avoiding measurement errors caused by movement or vibration. The design of the positioning mechanism takes into account the testing requirements of aluminum shells of different sizes. By adjusting the rotation of the threaded screw and the weight of the counterweight, it can adapt to aluminum shells of different specifications, improving the versatility of the device. Compared with high-end automated testing systems, the device of the present invention has a relatively simple structure and low manufacturing cost, making it more suitable for widespread application in small and medium-sized enterprises or production lines.

[0029] The above-mentioned aluminum shell detection device is used, and the method of use includes the following steps: S1. Start the feeding component: Start the third motor 60, which drives the sliding sleeve 55 within the sliding rail 54 through the first driving rod 58 and the second driving rod 59. The lifting block 56 in the sliding sleeve 55, under the action of the second spring 57, pushes the aluminum shell on the placement rack 51 along the inclined plate 52 onto the detection plate 23; When the aluminum shell is pushed onto the detection plate 23, the first motor 226 and the second motor 227 are started, and the first threaded screw 222 and the second threaded screw 223 rotate, driving the first slider 224 and the second slider 225 to move in the slide groove. The first positioning block 228 and the second positioning block 229 on the first slider 224 and the second slider 225 perform preliminary positioning on the aluminum shell. The first positioning block 228 pushes the second clamping block 231 to move toward the first clamping block 230 via the first spring 232, further clamping the aluminum shell to ensure its stability during the detection process. S2: Weight detection: After the aluminum shell is placed on the detection plate 23, the weight is transferred to the first connecting rod 29 and the second connecting rod 30 through the weighing plate 21. The first connecting rod 29 and the second connecting rod 30 act as a lever through the first cross bar 24, the second cross bar 25, the third cross bar 26, the first vertical rod 27 and the second vertical rod 28, so that the first pointer 31 indicates the weight of the aluminum shell on the first measuring disk 33; S3: Size detection: After the aluminum shell is stably positioned, the size detection component 4 starts to work. The first moving block 41 above the second clamping block 231 drives the third transmission rod 45 and the fourth transmission rod 46 to move through the transmission of the first transmission rod 43 and the second transmission rod 44. The movement of the third transmission rod 45 and the fourth transmission rod 46 causes the second moving block 42 to move on the amplification mechanism 47. S4: Reading dimensional data: The second moving block 42 slides in the moving grooves of the first measuring block 474 and the second measuring block 475 of the amplifying mechanism 47 and points out the data through the second pointer. Through the amplification effect of the amplifying mechanism 47, the dimensional data of the aluminum shell can be read, and the data detected by the weight detection component 2 and the size detection component 4 are recorded to determine whether the aluminum shell is qualified or to perform further processing on the aluminum shell according to the data; S5: After the inspection is completed, the aluminum shell is taken out. Under the action of the counterweight block 32, the first pointer 31 moves downward and touches the metal iron sheet to close the circuit. The third motor 60 is energized and started, and the steps in S1 are repeated. That is, through the transmission of the first driving rod 58 and the second driving rod 59, the sliding sleeve 55 slides in the sliding rail frame 54. The ejecting block 56 in the sliding sleeve 55 is pushed to the detection plate 23 along the inclined plate 52 under the action of the second spring 57, and the detection work is continued. At this time, the weight of the aluminum shell will cause the first pointer 31 to move upward, thereby separating from the metal iron sheet, disconnecting the closed circuit and stopping the third motor 60, ensuring that only one aluminum shell is pushed to the detection plate 23 in each detection cycle.
[0030] In summary, the present invention realizes the automatic pushing of the aluminum shell from the placement rack to the detection plate through the coordinated action of the third motor, the first driving rod and the second driving rod in the feeding component. This design reduces the tedious steps of manual feeding and improves the detection efficiency; the start and stop of the third motor are controlled by the closing / disconnection of the metal iron sheet and the circuit, thereby realizing the precise control of the feeding action. This design not only improves the detection efficiency, but also avoids the confusion and errors caused by excessive feeding. The detection process of the weight detection component and the size detection component in the present invention is consistent. Once the aluminum shell is pushed onto the detection plate, the weight and size can be simultaneously detected without the need for intermediate transportation, further improving the detection speed; the weight detection component utilizes the lever principle and the mechanical transmission structure to maintain stability while weighing. The mechanical transmission structure can accurately measure the weight of the aluminum shell and provide reliable data for quality control. The size detection component realizes the precise measurement of the size of the aluminum shell through the combination of the transmission rod and the amplification mechanism. The design of the amplification mechanism makes the reading of data more intuitive.
[0031] The present invention ensures the stability of the aluminum shell during testing by initially positioning the first and second positioning blocks in the positioning mechanism, and further clamping the first and second clamping blocks via springs, thereby avoiding measurement errors caused by movement or vibration. The design of the positioning mechanism takes into account the testing requirements of aluminum shells of different sizes. By adjusting the rotation of the threaded screw and the weight of the counterweight, it can adapt to aluminum shells of different specifications, improving the versatility of the device. Compared with high-end automated testing systems, the device of the present invention has a relatively simple structure and low manufacturing cost, making it more suitable for widespread application in small and medium-sized enterprises or production lines.

9. A method for using the aluminum shell detection device according to claim 8, characterized in that: The following steps are involved: S1. Start the feeding component: Start the third motor (60), and drive the sliding sleeve (55) in the sliding rail frame (54) through the transmission of the first driving rod (58) and the second driving rod (59). Under the action of the second spring (57), the lifting block (56) in the sliding sleeve (55) pushes the aluminum shell on the placement frame (51) along the inclined plate (52) to the detection plate (23); When the aluminum shell is pushed onto the detection plate (23), the first motor (226) and the second motor (227) are started, the first threaded screw (222) and the second threaded screw (223) rotate, driving the first slider (224) and the second slider (225) to move in the slide groove, the first positioning block (228) and the second positioning block (229) on the first slider (224) and the second slider (225) perform preliminary positioning on the aluminum shell, the first positioning block (228) pushes the second clamping block (231) to move toward the first clamping block (230) through the first spring (232), further clamping the aluminum shell to ensure its stability during the detection process; S2: Weight detection: After the aluminum shell is placed on the detection plate (23), the weight is transferred to the first connecting rod (29) and the second connecting rod (30) through the weighing plate (21). The first connecting rod (29) and the second connecting rod (30) act through the lever action of the first cross bar (24), the second cross bar (25), the third cross bar (26), the first vertical rod (27) and the second vertical rod (28), so that the first pointer (31) indicates the weight of the aluminum shell on the first measuring disk (33); S3: Dimension detection: After the aluminum shell is stably positioned, the dimension detection component (4) starts to work. The first moving block (41) above the second clamping block (231) drives the third transmission rod (45) and the fourth transmission rod (46) to move through the transmission of the first transmission rod (43) and the second transmission rod (44). The movement of the third transmission rod (45) and the fourth transmission rod (46) causes the second moving block (42) to move on the amplification mechanism (47); S4: Reading dimensional data: The second moving block (42) slides in the moving grooves on the first measuring block (474) and the second measuring block (475) of the amplifying mechanism (47) and points out the data through the second pointer. Through the amplifying effect of the amplifying mechanism (47), the dimensional data of the aluminum shell can be read, and the data detected by the weight detection component (2) and the dimensional detection component (4) are recorded to determine whether the aluminum shell is qualified or to perform the next step of processing on the aluminum shell according to the data; S5: After the inspection is completed, the aluminum shell is taken out. Under the action of the counterweight (32), the first pointer (31) moves downward and touches the metal iron sheet to close the circuit. The third motor (60) is energized and started, and the steps in S1 are repeated. That is, through the transmission of the first driving rod (58) and the second driving rod (59), the sliding sleeve (55) slides in the sliding rail (54). Under the action of the second spring (57), the lifting block (56) in the sliding sleeve (55) pushes the next aluminum shell on the placement rack (51) along the inclined plate (52) to the inspection plate (23) to continue the inspection work. At this time, the weight of the aluminum shell will cause the first pointer (31) to move upward, thereby separating from the metal iron sheet, disconnecting the closed circuit and stopping the third motor (60), ensuring that only one aluminum shell is pushed to the inspection plate (23) in each inspection cycle.
