[0030] Please also read Figures 1 to 9 , the lightweight edge computing device provided by an embodiment of the present invention is now described.

[0031] Reference Figures 1 to 3 The lightweight edge computing device of an embodiment of the present invention includes: a work box 100, a placing table 200 arranged in the work box 100, two clamping plates 300, and a detection device 400; the two clamping plates 300 are arranged on both sides of the placing table 200, and the bottom center of the placing table 200 has a vertically arranged first rotating shaft 210, and a first driving mechanism 500 for driving the first rotating shaft 210 to rotate is arranged in the work box 100, and a second driving mechanism 600 for driving the two clamping plates 300 to move toward and away from each other is arranged in the work box 100; both of the two clamping plates 300 are provided with a head 310 to be detected facing the detection device 400; a third driving mechanism 700 for driving the detection device 400 to move along a first straight line direction is arranged in the work box 100, and the first straight line direction is parallel to the moving direction of the clamping plate 300.

[0032] The placing table 200 is used to place the physical object to be measured. The two clamping plates 300 have the same height and are located above both sides of the placing table 200. The distance between the two heads 310 to be detected is parallel to the first straight line direction. The second driving mechanism 600 is used to drive the two clamping plates 300 to move toward or away from the physical object on the placing table 200. When the second driving mechanism 600 drives the two clamping plates 300 to move toward each other, the clamping plates 300 can clamp the physical object on the placing table 200, and cooperate with the placing table 200 to clamp and position the physical object to prevent the physical object from moving during the measurement process. At this time, the distance between the two heads 310 to be detected on the two clamping plates 300 is the length of the physical object in the first straight line direction at this time; then the third driving mechanism 700 drives the detection device 400 to move along the first straight line direction, so that the detection device 400 detects the two heads 310 to be detected during the movement, and obtains the distance between the two heads 310 to be detected, so as to obtain the length of the physical object in the first straight line direction at this time. After one inspection is completed, the clamping plate 300 moves in opposite directions to release the object, and the inspection device 400 is reset. Then the first driving mechanism 500 drives the placing table 200 to rotate to detect the size of the object in another direction. By repeating the above steps, the size of the object in multiple directions can be obtained, so as to facilitate the collection of the size information of the object and to establish a geometric entity on the computer. In the measurement process, no human assistance is required for clamping and positioning, which can reduce human labor, reduce the labor intensity of the measurement steps, and reduce the situation of clamping and positioning errors, so as to improve the measurement accuracy and efficiency. In addition, the size information of the measured object can be compared with the size information of the standard part to determine whether the current size of the object is qualified or defective, so as to facilitate the removal of defective products.

[0033] The clamping plate 300 of the lightweight edge computing device of this embodiment can move toward each other under the drive of the second driving mechanism 600 to clamp the physical object placed on the placing table 200 to clamp and position the physical object to be measured. Then, the detection device 400 detects the head to be detected 310 on the clamping plate 300 under the drive of the third driving mechanism 700 to detect the length of the current physical object in the first straight line direction; then the clamping plate 300 moves away from each other to release the physical object, and the detection device 400 is reset. Then, the first driving mechanism 500 drives the placing table 200 to rotate to detect the size of the physical object in another direction. By repeating the above steps, the sizes of the physical object in multiple directions can be obtained, so as to establish geometric entities on the computer or perform defective product detection. This lightweight edge computing device does not require human assistance for clamping and positioning during the measurement process, which can reduce manual labor, reduce the labor intensity of the measurement steps, and reduce clamping and positioning errors, so as to improve measurement accuracy and efficiency. In addition, the size information of the measured object can be compared with the size information of the standard part to determine whether the current size of the object is qualified or whether it is a defective product, so as to facilitate the removal of defective products.

[0034] It should be noted that the direction of the first straight line is perpendicular to the length direction of the vertically arranged first rotating shaft 210 .

[0035] In a preferred embodiment of the present invention, referring to Figure 2 and Figure 3 , the two clamping plates 300 are each provided with a sliding section 320, and the sliding section 320 is slidably connected to the working box 100; the second driving mechanism 600 includes a lifting platform 610 and a first screw driving assembly 620 for driving the lifting platform 610 to lift; both sides of the lifting platform 610 are hinged with hinge rods 611, and the ends of the two hinge rods 611 away from the lifting platform 610 are respectively hinged to the two clamping plates 300. The working box 100 is provided with a slide rail slidably connected to the sliding section 320, so as to facilitate the movement of the clamping plate 300 in the first straight line direction. The initial position of the lifting platform 610 is located below the clamping plate 300. The two sides of the lifting platform 610 are respectively hinged to the two clamping plates 300 through two hinge rods 611. When the lifting platform 610 is away from the clamping plate 300 in the first screw drive assembly 620, that is, when the lifting platform is driven by the first screw 621, the lifting platform drives the clamping plates 300 to move toward each other through the hinge rod 611. At this time, the clamping plates 300 can clamp the objects on the placing table 200 to clamp and position the objects and prevent the objects from shaking or shifting during the measurement process. Similarly, when the lifting platform 610 rises to gradually approach the clamping plates 300, the lifting platform 610 drives the clamping plates 300 to move away from each other through the hinge rod 611, so that the clamping plates 300 release the objects, which is convenient for the placing table 200 to rotate, so as to adjust the clamping angle of the objects and change the measurement angle of the objects.

[0036] In a preferred embodiment of the present invention, referring to Figure 3 Both clamping plates 300 are provided with abutting portions 330 for abutting against the workpiece, and the detection head 310 is arranged on the abutting portions 330; the sliding section 320 is provided with a first sliding groove 340 slidably connected with the abutting portions 330, and the sliding section 320 is provided with a compression spring 350 for driving the abutting portions 330 to return to the original position along the first straight line direction. The sliding section 320 is provided with a receiving groove for receiving the abutting part 330, and the abutting part 330 is provided with an extending end extending into the receiving groove, and a compression spring 350 is provided in the receiving groove to push the abutting part 330 to the outside; the first slide groove 340 is used to limit the sliding stroke of the abutting part 330 to prevent the abutting part 330 from falling off from the receiving groove, and ensure that the abutting part 330 can slide in the first slide groove 340; by providing a movable abutting part 330 with an elastic reset function, the clamping plate 300 can better fit various physical objects of different sizes when clamping the physical object, so as to facilitate the measurement of the size of the physical object. It should be noted that the head to be detected 310 is set at the top of the abutting part 330, so that the size of the physical object can be reflected through the two heads to be detected 310.

[0037] In a preferred embodiment of the present invention, referring to Figure 2 , Figure 4 , Figure 5 , Figure 8 , Fig. 9The first screw drive assembly 620 has a vertically arranged first screw 621, a first gear 622 coaxially arranged with the first screw 621, and a fixed vertical plate 623 slidably connected to the lifting platform 610; the first screw 621 is threadedly connected to the lifting platform 610; the first driving mechanism 500 has a second gear 510, and a gear mounting plate 110 and a second screw drive assembly 120 for driving the gear mounting plate 110 to reciprocate along the first straight line direction are arranged in the working box 100; one-way teeth 111 and fixed teeth 112 are respectively arranged on both sides of the gear mounting plate 110, the one-way teeth 111 are meshed with the second gear 510, and the fixed teeth 112 are meshed with the first gear 622. The tooth mounting plate 110 moves back and forth under the drive of the second screw drive assembly 120, and the multiple one-way teeth 111 and the multiple fixed teeth 112 are arranged in sequence along the first straight line direction; when the tooth mounting plate 110 moves forward under the drive of the second screw drive assembly 120, the one-way teeth 111 drive the second gear 510 to rotate, so as to drive the placing table 200 to rotate a certain angle, and the rotation angle is proportional to the length of the one-way teeth 111; at the same time, the fixed teeth 112 drive the first gear 622 to rotate, driving the lifting platform 610 to descend along the fixed vertical plate 623 and away from the clamping plate 300, so that the two clamping plates 300 move toward each other. It should be noted that the clamping plate 300 will clamp the object on the placing table 200 only after the placing table 200 stops rotating. The movement here can be achieved by setting the length of the one-way teeth 111 and the fixed teeth 112. Optimally, the physical object to be measured is generally square, and the angle at which the holding platform 200 rotates each time driven by the one-way teeth 111 can be set to ninety degrees. The measurement process is repeated four times to measure the size of each edge of the physical object. In order to prevent excessive clamping of the physical object and interference, the first gear 622 is connected to the first screw 621 through a safety coupling. After the clamping plate 300 clamps the physical object, the first gear 622 will not continue to transmit torque to the first screw 621, thereby avoiding jamming or overloading, and protecting the first screw drive assembly 620 from damage. Similarly, when the lifting platform 610 is in the highest position, it is the initial state. When the lifting platform 610 is driven to the highest position by the first gear 622, the first gear 622 will not continue to transmit torque to the first screw 621 to prevent offside.

[0038] It is worth mentioning that, refer to Figure 8 and Fig. 9When the tooth mounting plate 110 moves backward under the drive of the second screw drive assembly 120, the one-way tooth 111 moves backward, but no power is transmitted between the one-way tooth 111 and the second gear 510, so that the fixed tooth 112 can move backward and reset, and the lifting platform 610 moves up and resets to drive the clamping plate 300 to reset, but the placing platform 200 does not reset, so that the one-way tooth 111 can rotate in the same direction again when the tooth mounting plate 110 moves forward, so as to measure the size of the edge of the object at multiple angles. It can be understood that the one-way tooth 111 and the second gear 510 can be driven by a ratchet and a pawl, that is, the second gear 510 is a ratchet; the one-way tooth 111 is a pawl, as shown in the figure, then the one-way tooth 111 can transmit power to the second gear 510 when the tooth mounting plate 110 moves forward, and does not transmit power when the tooth mounting plate 110 moves backward. Among them, the pawl is reset by a torsion spring.

[0039] In a preferred embodiment of the present invention, referring to Figure 1 and Figure 6 , the lightweight edge computing device also includes: a main driving gear 800, a main driving device 810 for driving the main driving gear 800 to rotate; the second screw driving assembly 120 includes a second screw 121 whose length direction is parallel to the first straight line direction, and a third gear 122 coaxially arranged with the second screw 121; the second screw 121 is threadedly connected to the tooth mounting plate 110, and the third gear 122 is meshed with the main driving gear 800. The main driving device 810 is a driving motor, and the driving motor can drive the main driving gear 800 to rotate forward or reverse, that is, the third gear 122 is driven to rotate forward or reverse through the main driving gear 800, so as to drive the tooth mounting plate 110 to move back and forth along the first straight line direction, so as to drive the lifting platform 610 to move up and down, so as to drive the clamping plate 300 to move toward or away from each other, and drive the placing platform 200 to rotate in the same direction.

[0040] In a preferred embodiment of the present invention, referring to Figure 2 The working box 100 is provided with a second slide groove 130 whose length direction is parallel to the first straight line direction, and the tooth mounting plate 110 is slidably connected to the second slide groove 130 through the limit plate 113. The second slide groove 130 can ensure that the tooth mounting plate 110 moves back and forth along the first straight line direction, making the movement of the tooth mounting plate 110 more stable.

[0041] In a preferred embodiment of the present invention, referring to Figure 1 and Figure 6The third driving mechanism 700 includes a third screw rod 710 whose length direction is parallel to the first straight line direction, a movable column 720 threadedly connected to the third screw rod 710, and a fourth gear 730 coaxially arranged with the third screw rod 710; the detection device 400 is arranged on the movable column 720, and the main driving gear 800 is an incomplete gear; the main driving gear 800 is driven by the main driving device 810 and meshes with one of the third gear 122 or the fourth gear 730. When the main driving gear 800 rotates forward, it first drives the third gear 122 to rotate so that the gear mounting plate moves forward, so as to drive the physical object on the placing table 200 to rotate to the position to be tested, drive the lifting platform 610 to descend, and the two clamping plates 300 clamp and position the physical object on the placing table 200; then the incomplete gear disengages from the third gear 122 and engages with the fourth gear 730, which can drive the fourth gear 730 to rotate forward and drive the moving column 720 to move along the first straight line direction, so that the detection device 400 detects the two heads 310 to be detected on the two clamping plates 300 to calculate the distance between the two heads 310 to be detected, and obtain the length dimension of the physical object in the first straight line direction at this time. Then the incomplete gear is reversed, driving the fourth gear 730 to reverse, and the movable column 720 can be driven to reset along the first straight line direction to wait for the next measurement; then the incomplete gear is disengaged from the fourth gear 730, meshed with the third gear 122, and the third gear 122 is driven to reverse; the tooth mounting plate 110, the lifting platform 610, and the clamping plate 300 are reset to wait for the next measurement. Repeating the above steps, the edge size of the real object on the placing table 200 can be automatically measured multiple times, and multiple edge size data of the real object can be obtained, which is convenient for finding defective products or establishing a three-dimensional data model.

[0042] In a preferred embodiment of the present invention, referring to Figure 1 In order to make the moving column 720 more stable, the working box 100 is provided with a third slide groove 150 whose length direction is parallel to the first straight line direction, and the third slide groove 150 is slidably connected with the moving column 720. The third slide groove 150 can limit the moving direction of the moving column 720, and stipulate that the moving column 720 can only move along the first straight line direction, thereby ensuring the accuracy of the detection data.

[0043] In a preferred embodiment of the present invention, the lightweight edge computing device also includes: a controller; the detection device 400 has a detection sensor; the third screw rod 710 is provided with an encoder; the controller is electrically connected to the detection sensor, the encoder, and the main drive device 810. The detection sensor and the head to be detected 310 are both infrared sensors to cooperate with the controller for calculation; during the detection process of the moving column 720, when the detection sensor of the detection device 400 is opposite to one of the heads to be detected 310, the controller records the linear displacement parameters on the encoder at this time; when the detection sensor of the detection device 400 is opposite to another head to be detected 310, the controller records the linear displacement parameters on the encoder at this time, and after comparing and calculating the two linear displacement parameters, the distance between the two heads to be detected 310 can be obtained, and the length of the physical object in the first straight line direction at this time can be obtained. It should be noted that the controller can be a commonly used single-chip microcomputer or MCU control chip on the market, which has calculation control and logic operation functions to control the forward and reverse rotation of the main drive device 810 to calculate the distance between the two heads to be detected 310.

[0044] In a preferred embodiment of the present invention, referring to Figure 7 , the work box 100 is provided with a printing device 140 electrically connected to the controller just above the placing table 200. It should be noted that the controller can store the qualified size parameters of the physical object to be measured. After the size detection of the physical object to be measured is completed, the controller can compare the detected size data with the qualified size parameters. If the detected size data is unqualified, the controller controls the printing device 140 to print a mark on the upper surface of the physical object to mark the current physical object as a defective product, so as to facilitate the quality inspectors to screen out the defective products.

[0045] It is understandable that the printing device 140 can be a common printer such as an inkjet printer or a laser printer commonly used in the market, which can print marks on physical objects.

[0046] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
