Description

Technical Field

[0001] The invention relates to the field of clamping equipment, and in particular to a clamping device and a clamping method thereof for convenient detection of arts and crafts. Background Art

[0002] In the process of detecting arts and crafts, the clamping device plays a vital role. However, the clamping device under the existing technology still has many limitations in design and function. Most of the existing clamping devices are made of hard materials, such as metal or hard plastic. Although these materials have high strength and durability, they are easy to cause scratches or indentations on the surface of arts and crafts during the clamping process. Especially for those arts and crafts with delicate surfaces and fragile materials, such as ceramics, glass or finely carved works, this damage is particularly obvious; secondly, most of the existing clamping devices can only achieve basic clamping functions and lack adaptability and flexibility. Due to the different shapes, sizes and materials of arts and crafts, traditional clamping devices are often difficult to meet the needs of different works. In addition, the clamping device often cannot provide the necessary adjustments and functions during the clamping process, making it difficult for users to obtain the best observation angle and position when conducting inspections, which to a certain extent limits the efficiency and accuracy of the inspection work, increases the labor intensity of operators, and may also lead to human errors.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the invention

[0027] Furthermore, the clamping method of the first clamping arm and the second clamping arm comprises the following specific steps:

[0028] S1: The user inputs the size and weight of the arts and crafts into the console, and the console opens the control valve to inflate the airbag, and automatically sets the clamping pressure range of the airbag to M5-M6. Then the arts and crafts are placed flat on the placement table. The user turns on the first camera through the console, and the first camera detects the placement status of the arts and crafts and transmits it to the console, and then enters step S2;

[0029] S2: The user sets the size error range to L3-L4 through the console, and then measures the actual length of the arts and crafts to L10 and the actual width to L20 through the first camera. Then the console automatically sets the standard gas output of the gas cylinder to N according to the standard weight G of the arts and crafts, and opens Q electric valves, so that Q cylinders lift Q support rods to lift the arts and crafts. Then the first clamping arm and the second clamping arm move down to clamp the arts and crafts. The sub-control board records the air pressure of the airbag as M7, and the sub-control board records the air pressure of the airbag as M7. The control panel records the total air pressure of Q cylinders as Q1 and automatically calculates the total weight of the arts and crafts as G1; if L4>L10-L1>L3, L4>L20-L2>L3, and G2>G1-G>G3, M5<M7<M6, the control console automatically controls the first clamping arm and the second clamping arm to move down to clamp the arts and crafts through the position data detected by the first camera, and enters step S3; if any of the above conditions is not met, it is proved that the quality is unqualified, and the control console issues an alarm;

[0030] S3: The console automatically determines that the rotatable height is L21 according to the width of the arts and crafts. When the first linear module and the second linear module rise to L21 at the same time, the first clamping arm and the second clamping arm rotate at the same time, so that the arts and crafts are perpendicular to the base plane. At this time, the console displays that it is clamping, reminding the user to perform manual inspection.

[0031] Furthermore, step S2 includes the following specific operation steps:

[0032] The specific judgment method is as follows:

[0033] S21: Obtain detection information of the arts and crafts through the control console. If L20-L2 or L10-L1 is not between L4 and L3, and G2>G1-G>G3, M5<M7<M6, it is proved that the size of the arts and crafts is unqualified. The control console displays that the arts and crafts are too long or too wide, and reminds the user to take down the arts and crafts; if L4>L10-L1>L3, L4>L20-L2>L3, M5<M7<M6, and G1-G is not between G2 and G3, then enter step S22;

[0034] S22: The user turns on the second camera through the console. Based on the position data detected by the first camera, the console automatically controls the first clamping arm and the second clamping arm to clamp the arts and crafts and to rise and rotate until the arts and crafts are parallel to the base. The first clamping arm and the second clamping arm clamp the arts and crafts and to descend so that the upper end surface of the arts and crafts and the second camera are in the same plane, so that the second camera and the first camera detect the upper end surface. Then the first clamping arm and the second clamping arm flip the arts and crafts so that the second camera detects the bottom end surface of the arts and crafts. If the second camera detects that the upper end surface or the lower end surface is uneven, the first camera locates the uneven area on the surface of the arts and crafts and displays it on the console. If the second camera does not detect that the upper end surface or the lower end surface is uneven, if G1-G<G2, the console displays that the density of the arts and crafts is too low and the hardness is poor. If G1-G>G2, the console displays that the density of the arts and crafts is too high or contains impurities.

[0035] Compared with the prior art, the present invention has the following beneficial effects: the present invention can avoid manual positioning operation during clamping, avoid inconvenience in clamping when the clamping device clamps arts and crafts of different sizes, thereby reducing the difficulty of clamping, and reduce the damage of the clamping parts to the arts and crafts through the airbag; at the same time, during the clamping process, the first camera and the second camera form a binocular vision system to measure whether the quality and size of the artwork are qualified, thereby reducing the inspection time of the arts and crafts, and reducing the labor intensity of the operator and the generation of human errors.

[0050] An assembly cavity 22 for placing a rotating motor 21 is provided inside the base 110, a placement cavity 24 with a plurality of cylinders 23 is provided inside the placement table 111, and a rotating shaft 112 is provided between the placement table 111 and the base 110, so that the placement table 111 can rotate on the base 110 through the rotating shaft 112, and the plurality of cylinders 23 are all connected to the gas cylinder 19, wherein a support rod 25 is inserted into any one of the cylinders 23, and a plurality of openings 26 for the support rods 25 to pass through are provided on the top outer surface of the placement table 111, and an air pressure sensor 27 is also provided on the cylinder 23. It is worth noting that any one of the cylinders 23 is independently connected to the gas cylinder 19 through an air pipe, and an electric valve 29 connected to the control console 2 electric wire is provided at the air inlet end of any one of the cylinders 23, and the electric valve 29 is used to control the air intake amount of the cylinder 23.

[0051] A first electric telescopic rod 121 is provided between the first clamping arm 12 and the first linear module 14, a second electric telescopic rod 131 is provided between the second clamping arm 13 and the second linear module 15, one end of the first electric telescopic rod 121 is provided with a first electric rotating part 122 for rotating the first clamping arm 12, and one end of the second electric telescopic rod 131 is provided with a second electric rotating part 132 for rotating the second clamping arm 13, wherein the first electric telescopic rod 121, the second electric telescopic rod 131, the first electric rotating part 122, and the second electric rotating part 132 are all connected to the sub-control board 17 with electric wires.

[0052] The first clamping arm 12 and the second clamping arm 13 have the same shape and structure. The first clamping arm 12 includes an assembly shell 127, a main clamping plate 120 arranged at one end of the assembly shell 127, a sub-clamping plate 123 movably connected to the main clamping plate 120, and an air bag 124 arranged on the main clamping plate 120 and the sub-clamping plate 123; wherein the air bag 124 is connected to the gas cylinder 19 through a hose, and a control valve 126 for controlling the air intake of the air bag 124 is provided at one end of the gas cylinder 19. In the initial state, a clamping port is formed between the main clamping plate 120 and the sub-clamping plate 123.

[0053] The control console 2 is provided with a detection system, which includes a detection module and a processing module. The detection module includes a length detection submodule, a width detection submodule, a thickness detection submodule, a weight detection submodule, an identification detection submodule and a distance detection submodule. The operation module includes a telescopic submodule, a rotation submodule and an early warning submodule.

[0054] In this embodiment, the base 110 is used to facilitate the user to operate the first clamping arm 12 and the second clamping arm 13 to clamp the arts and crafts; in the initial state, no gas enters the cylinder 23, and the support rod 25 is located inside the base 110;

[0055] The specific clamping method is:

[0056] S1: The user inputs the standard length L1, standard width L2 and standard weight G of the arts and crafts into the console 2, and the console 2 opens the control valve 126 to inflate the airbag 124, and automatically sets the clamping air pressure range of the airbag 124 to M5-M6 according to the thickness of the arts and crafts, and then places the arts and crafts flat on the placement table 111. The user turns on the first camera 11 through the console 2, and the first camera 11 detects the placement state of the arts and crafts and transmits it to the console 2. The console 2 controls the placement table 111 to rotate, so that the arts and crafts are automatically centered on the placement table 111, and then enters step S2;

[0057] S2: The user opens the first camera 11 through the console 2 and sets the error range to L3-L4. Then, the actual length of the arts and crafts is measured by the first camera 11 as L10 and the actual width is measured as L20. Then, the console 2 automatically sets the standard gas output of the gas cylinder to N according to the standard weight G of the arts and crafts. The console 2 opens Q electric valves 29 according to the size data and position information detected by the first camera 11, so that the gas in the gas cylinder 19 enters the Q cylinders 23. The Q cylinders 23 lift up the Q support rods 25 to lift up the arts and crafts. At the same time, the console automatically controls the console 2 according to the position data detected by the first camera 11. The first clamping arm 12 and the second clamping arm 13 are controlled to move downward to clamp the arts and crafts, and the sub-control board 17 records the air pressure of the airbag 124 as M7. At the same time, the sub-control board 17 records the total air pressure of the Q cylinders 23 as Q1 and automatically calculates the total weight of the arts and crafts as G1; if L4>L10-L1>L3, L4>L20-L2>L3, and G2>G1-G>G3, M5<M7<M6, then the console uses the position data detected by the first camera 11, and the console 2 automatically controls the first clamping arm 12 and the second clamping arm 13 to move downward to clamp the arts and crafts, and enters step S3; if any of the above conditions is not met, it is proved that the quality is unqualified, and the console 2 issues an alarm;

[0058] It should be further explained that when the control console 2 receives the position data detected by the first camera 11, the control console 2 will automatically locate and open the several electric valves 29 at the position of the arts and crafts according to the position of the arts and crafts, so that the several support rods 25 lift up the arts and crafts, and then the control console 2 automatically controls the first electric telescopic rod 121 to extend or shorten the distance, and controls the second electric telescopic rod 131 to extend or shorten the distance, and then the control console automatically controls the first clamping arm 12 and the second clamping arm 13 to move downward, so that the main clamping plate 120 contacts the surface of one end of the arts and crafts. After that, the sub-control board 17 controls the auxiliary clamping plate 123 to move so that the auxiliary clamping plate 123 cooperates with the main clamping plate 120 to clamp the arts and crafts. When M5<M7<M6, it is proved that the first clamping arm 12 or the second clamping arm 13 clamps the arts and crafts and proves that the thickness of the arts and crafts is qualified. The control console 2 automatically controls the first clamping arm 12 and the second clamping arm 13 to clamp the arts and crafts and make the arts and crafts centered. Then, the first linear module 14 and the second linear module 15 control the arts and crafts to rise. If M7 is not between M5 and M6, it is proved that the thickness of the arts and crafts is unqualified.

[0059] S3: The control console 2 automatically determines that the rotatable height is L21 according to the width of the arts and crafts. When the first linear module 14 and the second linear module 15 rise to L21 at the same time, the first clamping arm 12 and the second clamping arm 13 rotate at the same time, so that the arts and crafts are perpendicular to the base plane. At this time, the control console 2 displays that it is clamping, reminding the user to perform a manual inspection.

[0060] Through the above steps, manual positioning operation can be avoided during clamping, and the clamping device can avoid clamping inconvenience when clamping arts and crafts of different sizes, thereby reducing the clamping difficulty, and the airbag can reduce the damage of the clamping member to the arts and crafts;

[0061] Specifically, step S2 also includes a method for determining the reasons for the failure of the arts and crafts;

[0062] The specific judgment method is as follows:

[0063] S21: Obtain detection information of the arts and crafts through the control console 2. If L20-L2 or L10-L1 is not between L4 and L3, and G2>G1-G>G3, M5<M7<M6, it is proved that the size of the arts and crafts is unqualified. The control console 2 displays that the arts and crafts is too long or too wide, and reminds the user to take down the arts and crafts; if L4>L10-L1>L3, L4>L20-L2>L3, M5<M7<M6, and G1-G is not between G2 and G3, then enter step S22;

[0064] S22: The user turns on the second camera 10 through the console 2. Based on the position data detected by the first camera 11, the console 2 automatically controls the first clamping arm 12 and the second clamping arm 13 to hold the arts and crafts and to raise and rotate until the arts and crafts are parallel to the base 110. The first clamping arm 12 and the second clamping arm 13 hold the arts and crafts and lower them so that the upper end surface of the arts and crafts and the second camera 10 are in the same plane. The second camera 10 and the first camera 11 detect the upper end surface. Then, the first clamping arm 1 2 and the second clamping arm 13 flip the arts and crafts, so that the second camera 10 detects the bottom end surface of the arts and crafts; if the second camera 10 detects that the upper end surface or the lower end surface is uneven, the first camera 11 locates the uneven area on the surface of the arts and crafts and displays it on the console 2; if the second camera 10 does not detect that the upper end surface or the lower end surface is uneven, if G1-G<G2, the console 2 displays that the density of the arts and crafts is too low and the hardness is poor; if G1-G>G2, the console 2 displays that the density of the arts and crafts is too high or contains impurities;

[0065] It is worth noting that, since the base 110 is rotatable, during the detection process of step S22 , the user can rotate the base 110 so that the second camera 10 and the first camera 11 can detect the plane of the completed arts and crafts.

[0066] It should be further explained that step 21 also includes a method for detecting whether the quality of the arts and crafts is balanced;

[0067] The specific detection method is:

[0068] S211: Obtain detection information of the arts and crafts through the control console 2. If L4>L10-L1>L3, L4>L20-L2>L3, and G2>G1-G>G3, M5<M7<M6, the user divides the arts and crafts into n equal parts (the minimum value of n is 3), and the control console 2 measures the standard mass of each part of the arts and crafts as N1. The control console 2 supplies gas to n cylinders 23 respectively with the standard mass N1. The standard air pressure in the n cylinders 23 is M8. The user sets the air pressure error value to M9-M10, and then enters step S212;

[0069] S212: The user clamps the arts and crafts in the center through the first clamping arm 12 and the second clamping arm 13 of the console, and the console 2 supplies gas to n cylinders 23 respectively, so that the n cylinders 23 lift up the arts and crafts. At this time, the air pressure value of any cylinder is M11. If M9>M11-M8>M10, the console 2 displays that the quality of the arts and crafts is uniform. If any one of M11-M8>M9, it means that the density of this part is too high and the density of other parts is too low. The console 2 displays that the quality of the arts and crafts is uneven.

[0070] Furthermore, step S1 also includes a method for correcting the clamping position of the arts and crafts;

[0071] The specific correction methods are:

[0072] S11: The user turns on the first camera 11 through the console 2, and the first camera 11 detects the placement status of the arts and crafts and transmits it to the console 2. If the position of the arts and crafts is not centered, the console 2 automatically controls the placement table 111 to rotate so that the side of the arts and crafts are parallel to the first clamping arm 12 and the second clamping arm 13 respectively, and the first clamping arm 12 and the second clamping arm 13 move down to clamp the arts and crafts, and then enter step S12;

[0073] S12: The user turns on the correction clamping arm 18 through the control console 2. The control console 2 automatically measures the rising height as L9 according to the length of the longer end of the handicraft. After the first clamping arm 12 and the second clamping arm 13 rise to L9, the first clamping arm 12 and the second clamping arm 13 rotate the handicraft so that one end of the handicraft enters the correction clamping arm 18. Then the first clamping arm 12 and the second clamping arm 13 cancel the clamping of the handicraft and rise to the center line of the handicraft. The first clamping arm 12 and the second clamping arm 13 clamp the handicraft again and move it down. The first clamping arm 12 and the second clamping arm 13 are rotated to place the handicraft in parallel on the placement table 111 to complete the correction.

If L4>L10-L1>L3, L4>L20-L2>L3, M5<M7<M6, and G1-G is not between G2 and G3, then enter step S22. S22: The user turns on the second camera (10) through the control console (2). Based on the position data detected by the first camera (11), the control console (2) automatically controls the first clamping arm (12) and the second clamping arm (13) to clamp the arts and crafts and raise and rotate until the arts and crafts are parallel to the base (110). The first clamping arm (12) and the second clamping arm (13) clamp the arts and crafts and lower them so that the upper end surface of the arts and crafts and the second camera (10) are in the same plane. The second camera (10) and the first camera (11) detect the upper end surface. Then the first clamping arm (12) and the second clamping arm (13) clamp the arts and crafts and lower them so that the upper end surface of the arts and crafts and the second camera (10) are in the same plane. The holding arm (12) and the second clamping arm (13) flip the arts and crafts so that the second camera (10) detects the bottom end surface of the arts and crafts; if the second camera (10) detects that the upper end surface or the lower end surface is uneven, the first camera (11) locates the uneven area on the surface of the arts and crafts and displays it on the console (2); if the second camera (10) does not detect that the upper end surface or the lower end surface is uneven, if G1-G<G2, the console (2) displays that the density of the arts and crafts is too low and the hardness is poor; if G1-G>G2, the console (2) displays that the density of the arts and crafts is too high or contains impurities.
