[0002] In the automated production process of a painting workshop, after vehicle painting is completed, color difference detection is a key quality control link. A traditional color difference detection system usually consists of a robot body and a color difference meter. The color difference meter needs to be perpendicular to the vehicle surface to accurately identify the color difference. However, during the actual working process, the color difference meter is directly connected to the robot manipulator. When the color difference meter contacts the vehicle body surface, it is very difficult for the manipulator to keep the color difference meter perpendicular to the vehicle body surface, thus affecting the accuracy of color difference identification.

[0003] In view of this, it is necessary to propose an adaptive auxiliary bracket to solve or at least alleviate the above technical problems. Summary of the Utility Model

[0039] In the painting process of the painting workshop, color difference detection is a crucial link. After the vehicle is painted, a color difference robot is required to conduct detailed color difference detection to ensure the consistency and aesthetics of the spraying effect. The color difference robot mainly consists of a robot body and a color difference meter. The color difference meter is a high-precision optical detection device that determines color consistency by measuring the chromaticity of the reflected light. Since the vehicle appearance will let consumers intuitively feel the texture of the vehicle, the accuracy of the color difference detection results must be guaranteed.

[0040] However, according to the applicant's observation and research, in the actual operation of the painting workshop, since the color difference meter is directly connected to the robotic arm of the robot, this design makes it difficult for the lens axis of the color difference meter to be perpendicular to the vehicle body surface during the actual detection process. When the color difference meter touches the vehicle body surface, due to the poor adaptability of the robotic arm and the irregularity of the vehicle body surface, the color difference meter often has an angular deviation, resulting in inaccurate color difference detection results. This error not only affects the evaluation of the painting quality but also may bring unnecessary trouble to the subsequent repair and adjustment work.

[0041] In view of this, the present utility model proposes an adaptive auxiliary bracket to solve the above technical problems.

[0042] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the adaptive auxiliary bracket 100 includes a first fixing plate 1, a second fixing plate 2, at least two pneumatic rods 3, a first connecting member 4 and a second connecting member 5. Among them, the first fixing plate 1 is provided with a receiving position 11 for installing the color difference meter 200; the pneumatic rod 3 includes a cylinder barrel 32 and a telescopic rod 31, and the cylinder barrels 32 communicate with each other; the first connecting member 4 is installed between the first fixing plate 1 and the telescopic rod 31, so that the telescopic rod 31 is rotatably connected to the first fixing plate 1; the second connecting member 5 is installed between the second fixing plate 2 and the cylinder barrel 32, so that the cylinder barrel 32 is rotatably connected to the second fixing plate 2.

[0043] The adaptive auxiliary bracket 100 is used to automatically correct the angle between the color difference meter 200 and the vehicle body surface, so that the lens of the color difference meter 200 can be combined with the vehicle body surface. Specifically, a first fixing plate 1, a first connecting member 4, a pneumatic rod 3, a second connecting member 5 and a second fixing plate 2 are sequentially arranged from the direction of the first fixing plate 1 to the second fixing plate 2. Among them, there are at least two pneumatic rods 3. When only two pneumatic rods 3 are provided, the two pneumatic rods 3 need to be symmetrically arranged along the horizontal axis of the accommodating hole for installing the color difference meter 200, and the two pneumatic rods 3 are not parallel to each other. The telescopic rod 31 can telescopically move in the cylinder 32. When the volume of the gas in the cylinder 32 decreases, the telescopic rod 31 retracts into the cylinder 32. When the volume of the gas in the cylinder 32 increases, the telescopic rod 31 extends out of the cylinder 32. By connecting the cylinders 32 of each pneumatic rod 3, the cylinders 32 can exchange gas. When one of the telescopic rods 31 retracts into its corresponding cylinder 32 under the action of an external force, the gas in this cylinder 32 is transported to the remaining cylinders 32, so that the telescopic rods 31 corresponding to the remaining cylinders 32 extend out of the cylinders 32. The first connecting member 4 and the second connecting member 5 can rotatably connect the two ends of the pneumatic rod 3 to the first fixing plate 1 and the second fixing plate 2 respectively, which is more convenient for adjusting the angle between the first fixing plate 1 and the second fixing plate 2. In this embodiment, six pneumatic rods 3 are provided, and the six pneumatic rods 3 are all obliquely arranged between the first fixing plate 1 and the second fixing plate 2. The first connecting member 4 and the second connecting member 5 have a damping effect in their own structures and are arranged corresponding to the pneumatic rods 3. By using multiple pneumatic rods 3, the stability of the adaptive auxiliary bracket 100 can be effectively improved.

[0044] In this embodiment, the usage process of the adaptive auxiliary bracket 100 is as follows: First, install the color difference meter 200 in the accommodation position 11, and fill the cylinder 32 with gas so that the telescopic rod 31 can support the first fixing plate 1 and the color difference meter 200. After filling the cylinder 32 with a preset amount of gas, bring the adaptive auxiliary bracket 100 with the color difference meter 200 installed close to the vehicle body surface. As the color difference meter 200 gradually approaches the vehicle body surface, the vehicle body surface gradually exerts pressure on the color difference meter 200. The color difference meter 200 transmits the pressure to the first fixing plate 1 through the accommodation position 11. The first fixing plate 1 transmits the pressure to the telescopic rod 31 through the first connecting member 4, causing the telescopic rod 31 under the action of the pressure to retract into the cylinder 32. Since the cylinders 32 are interconnected, the gas in the cylinder 32 under the action of the pressure flows into the other cylinders 32, causing the corresponding telescopic rods 31 to extend and driving the first fixing plate 1 to move. And due to the action of force, the first connecting member 4 and the second connecting member 5 rotate. Under the combined action of the pneumatic rod 3, the first connecting member 4, and the second connecting member 5, the angle of the first fixing plate 1 changes, thereby driving the color difference meter 200 to rotate or move, so that the lens of the color difference meter 200 gradually fits the vehicle body surface, and finally the central axis of the lens of the color difference meter 200 is perpendicular to the vehicle body surface. In this process, the adaptive auxiliary bracket 100 does not need to be equipped with any control devices, sensors, or other electronic devices, and completely adjusts the angle of the color difference meter 200 adaptively according to the force received by the color difference meter 200.

[0045] In the embodiment provided by the present utility model, the adaptive auxiliary bracket 100 includes a first fixing plate 1, a second fixing plate 2, at least two pneumatic rods 3, a first connecting member 4, and a second connecting member 5. Among them, the first fixing plate 1 is provided with an accommodation position 11 for installing the color difference meter 200; the pneumatic rod 3 includes a cylinder 32 and a telescopic rod 31, and the cylinders 32 are interconnected with each other; the first connecting member 4 is installed between the first fixing plate 1 and the telescopic rod 31, so that the telescopic rod 31 is rotatably connected to the first fixing plate 1; the second connecting member 5 is installed between the second fixing plate 2 and the cylinder 32, so that the cylinder 32 is rotatably connected to the second fixing plate 2. Through this setting, when the adaptive auxiliary bracket 100 with the color difference meter 200 installed gradually approaches the vehicle body surface, since the vehicle body surface exerts a reaction force on the color difference meter 200 and the cylinders 32 are interconnected, the telescopic rod 31 under the action of the reaction force retracts into the cylinder 32, while the other telescopic rods 31 extend out of the cylinder 32. At the same time, in cooperation with the first connecting member 4 and the second connecting member 5, the angle of the first fixing plate 1 can be adjusted adaptively, so that the lens of the color difference meter 200 can be closely attached to the vehicle body surface, thereby improving the accuracy of color difference recognition.

[0046] More specifically, the first fixing plate 1 includes at least two front mounting positions 12, and the second fixing plate 2 includes at least two rear mounting positions 21. At the same time, the projection of the front mounting position 12 vertically projected onto the second fixing plate 2 is defined as the front projection; the rear mounting position 21 corresponding to the front projection does not coincide with the front mounting position 12; both ends of the pneumatic rod 3 are respectively installed between the front mounting position 12 and the rear mounting position 21. For details, please refer to Figures 1 to 3 , in an embodiment of the present utility model, the first fixing plate 1 includes three front mounting positions 12, namely the first front mounting position 12a, the second front mounting position 12b, and the third front mounting position 12c. Correspondingly, the second fixing plate 2 includes three rear mounting positions 21, namely the first rear mounting position 21a, the second rear mounting position 21b, and the third rear mounting position 21c. As Figure 3 shown, the projection of the front mounting position 12 vertically projected onto the plane of the second fixing plate 2 is the front projection, and the rear mounting position 21 corresponding to the front projection does not coincide with the front mounting position 12. For example, the first front mounting position 12a is correspondingly connected to the first rear mounting position 21a and the third rear mounting position 21c, then the first front projection of the first front mounting position 12a on the plane of the second fixing plate 2 does not coincide with both the first rear mounting position 21a and the third rear mounting position 21c. Through this setting, it can be ensured that the pneumatic rod 3 is inclinedly installed between the front mounting position 12 and the rear mounting position 21, forming a triangular support structure, thereby improving the stability of the adaptive auxiliary bracket 100 provided by the embodiment of the present utility model.

[0047] Furthermore, one front mounting position 12 is respectively connected to two pneumatic rods 3 through two first connecting members 4, and the two pneumatic rods 3 are respectively connected to two adjacent rear mounting positions 21 through two second connecting members 5. Please refer to Figure 3 , first, it is defined that: a first connecting member 4, a pneumatic rod 3, and a second connecting member 5 are sequentially connected to form a movable mechanism. The first front mounting position 12a is connected to the first rear mounting position 21a and the third rear mounting position 21c respectively through two movable mechanisms. Similarly, the second front mounting position 12b is connected to the first rear mounting position 21a and the second rear mounting position 21b respectively through two movable mechanisms, and the third rear mounting position 21c is connected to the second rear mounting position 21b and the third rear mounting position 21c respectively through two movable mechanisms, that is, each front mounting position 12 is connected to two adjacent rear mounting positions 21 closest to this front mounting position 12 through two movable mechanisms. This setting can, on the basis of ensuring the stability of the adaptive auxiliary bracket 100, prevent the pneumatic rods 3 from crossing each other, ensure the flexibility of the structure of the adaptive auxiliary bracket 100, and facilitate flexibly adjusting the inclination angle of the first fixing plate 1 according to the external force received.

[0048] In an embodiment of the present utility model, the first connecting member 4 includes a first ball head rod 41 and a first ball seat 42. The ball head end of the first ball head rod 41 can rotate within the first ball seat 42. The other end of the first ball head rod 41 is hinged to the first fixing plate 1, and the first ball seat 42 is connected to the telescopic rod 31. The second connecting member 5 includes a second ball head rod 51 and a second ball seat 52. The ball head end of the second ball head rod 51 can rotate within the second ball seat 52. The other end of the second ball head rod 51 is fixedly connected to the second fixing plate 2, and the second ball head rod 51 is installed in the cylinder barrel 32. Specifically, please refer to Figure 1 , Figure 5 and Figure 6 , in the direction from the front mounting position 12 to the rear mounting position 21, the first fixing plate 1, the first ball head rod 41, the first ball seat 42, the telescopic rod 31, the cylinder barrel 32, the second ball head rod 51, the second ball seat 52 and the second fixing plate 2 are respectively arranged. The first ball head rod 41 has a ball head end and a hinged end. The overall shape of the ball head end is spherical. The first ball seat 42 is provided with a groove matching the ball head at the ball head end. The ball head can rotate in all directions within the groove, so that the telescopic rod 31 can rotate around a certain range of the front mounting position 12. The hinged end is hinged to the first fixing plate 1, enabling the first ball head rod 41 to rotate around the hinged direction, increasing the degree of freedom of the telescopic rod 31 and improving the flexibility of the rotation of the telescopic rod 31. The structure of the second connecting member 5 is generally the same as that of the first connecting member 4. The second ball seat 52 of the second connecting member 5 is fixedly installed on the second fixing plate 2. The connection method can be welding, threaded connection or plug-in connection. The ball head end of the second ball head rod 51 is installed in the second ball seat 52, and the other end is threadedly connected to the cylinder barrel 32. If the second ball seat 52 is hinged on the second fixing plate 2, the degree of freedom of the pneumatic rod 3 is too much and it cannot support the first fixing plate 1. Through this setting, the pneumatic rod 3 can not only support the first fixing plate 1, but also ensure the flexibility of the operation of the first fixing plate 1 and improve the efficiency of color difference recognition. The first connecting member 4 and the second connecting member 5 include one of a universal ball damping rotating shaft and a ball cage universal rotating shaft.

[0049] Furthermore, in an embodiment of the present utility model, a first covering member 43 for covering the ball head end of the first ball head rod 41 is provided on the first ball seat 42, and a second covering member 53 for covering the ball head end of the second ball head rod 51 is provided on the second ball seat 52. Specifically, please refer to Figure 5 and Figure 6, after the ball head end of the first ball head rod 41 is installed on the first ball socket 42, the first cover 43 is covered on the opening of the first ball socket 42; similarly, after the ball head end of the second ball head rod 51 is installed on the second ball socket 52, the second cover 53 is covered on the opening of the second ball socket 52. Through this setting, the ball head ends of the first ball head rod 41 and the second ball head rod 51 can be protected from the erosion of dust, moisture and other pollutants, extending their service life; at the same time, small particles or other foreign objects are prevented from entering between the ball head rod and the ball socket, avoiding affecting their rotational performance.

[0050] In an embodiment of the present utility model, the adaptive auxiliary bracket 100 further includes a tee member 6 installed on the second fixing plate 2. The tee members 6 are arranged in one-to-one correspondence with the pneumatic rods 3. The tee member 6 is communicated with its corresponding pneumatic rod 3, and the tee members 6 are communicated with each other. As Figure 1 With Figure 2 , the number of the tee members 6 is the same as that of the pneumatic rods 3, and the tee members 6 are arranged on the second fixing plate 2 closer to the cylinder barrel 32. In this embodiment, six pneumatic rods 3 are provided, and six tee members 6 are also provided. Among them, the tee member 6 includes a first air port, a second air port and a third air port. The first air port is used to communicate with its corresponding pneumatic rod 3, and the second air port and the third air port are used to communicate with two adjacent tee members 6. With such a setting, the tee members 6 can communicate with each other. When the cylinder barrel 32 in the pneumatic rod 3 needs to intake or exhaust air, the gas exchanges between the cylinder barrels 32 through each tee member 6, achieving the purpose of connecting the cylinder barrels 32 with each other. Compared with the technical solution of directly providing two air holes on each cylinder barrel 32 and connecting the two air holes with two adjacent cylinder barrels 32 respectively, the use of the tee member 6 can avoid customizing the cylinder barrel 32 with two air holes, thereby reducing the production cost and design difficulty.

[0051] In an embodiment of the present utility model, the first fixing plate 1 includes a mounting rod 13 for mounting the color difference meter 200. Specifically, please refer to Figure 4 , the mounting rod 13 is arranged parallel to the surface of the color difference meter 200. After the lens of the color difference meter 200 passes through the accommodating position 11, the main body of the color difference meter 200 needs to be fixed to avoid shaking during use and affecting the color difference detection accuracy. Among them, the connection method between the main body of the color difference meter 200 and the mounting rod 13 is one of tie-tape connection, plug connection, chain connection, and buckle connection.

[0052] Furthermore, in an embodiment of the present utility model, a plurality of balance holes 14 are formed on the first fixing plate 1. The balance holes 14 are used to adjust the center of gravity of the first fixing plate 1, so that the first fixing plate 1 with the color difference meter 200 installed is always parallel to the second fixing plate 2 in the initial state. Specifically, please refer to Figure 3, on the basis that the accommodating position 11 is provided on the first fixing plate 1, a plurality of balance holes 14 with different sizes are further provided on the first fixing plate 1. The positions, sizes and quantities of the balance holes 14 need to be designed according to various factors such as the center of gravity position of the color difference meter 200, the weight of the first fixing plate 1, and the supporting force of the pneumatic rod 3. Through this setting, after the adaptive auxiliary bracket 100 installs the color difference meter 200 and inflates the cylinder barrel 32, the first fixing plate 1 and the second fixing plate 2 can ensure to be parallel when not under the action of external forces other than gravity. This design facilitates the color difference meter 200 to rotate at any angle, which is beneficial for the color difference meter 200 to quickly adjust to a suitable angle through the adaptive auxiliary bracket 100 to detect the color difference of the vehicle body surface, avoiding the situation that the angle between the central axis of the color difference meter 200 and the vehicle body surface is too large due to the non-parallelism of the first fixing plate 1 and the second fixing plate 2 in the initial state. In this case, the first fixing plate 1 needs to first return to a state parallel to the second fixing plate 2 under the action of the reaction force on the vehicle body surface, and then rotate to an angle that fits the vehicle body surface.

[0053] In an embodiment of the present utility model, a connection disk 7 is installed on one side of the second fixing plate 2, and the connection disk 7 is connected to the robotic arm 300. For details, please refer to Figure 1 , Figure 2 and Figure 4 . After the robotic arm 300 is connected to the connection disk 7, the robotic arm 300 can drive the entire adaptive auxiliary bracket 100 to move. The connection disk 7 provides a standardized interface, enabling the second fixing plate 2 to be conveniently connected and positioned with the robotic arm 300. At the same time, the connection disk 7 and the robotic arm 300 can be detachably connected, enabling the adaptive auxiliary bracket 100 to replace different models of robotic arms 300 according to different usage scenarios, improving the utilization rate of the adaptive auxiliary bracket 100. In addition, the connection disk 7 and the second fixing plate 2 are detachably connected, enabling different models of connection disks 7 to be installed on the second fixing plate 2, thereby also enabling the adaptive auxiliary bracket 100 to adapt to different models of robotic arms 300 and improving its applicability.

[0054] In an embodiment of the present utility model, a pressure sensor is provided between the first connecting member 4 and the pneumatic rod 3. When performing color difference detection, the color difference meter 200 applies a force to the vehicle body surface. Excessive force may cause wear on the vehicle body surface. Therefore, a pressure sensor is provided between the first connecting member 4 and the pneumatic rod 3 to indirectly monitor the magnitude of the force applied by the color difference meter 200 to the vehicle body surface. Before performing color difference detection, it is necessary to test the maximum pressure value that causes wear on the vehicle body surface monitored by the pressure sensor between the first connecting member 4 and the pneumatic rod 3, and use 0.8 times of this pressure value as the alarm preset value. When performing color difference detection, when the pressure monitored by the pressure sensor is greater than the alarm preset value, the robotic arm 300 immediately stops operating, thereby effectively reducing the possibility of damage to the vehicle body or the color difference meter caused by excessive pressure.

[0055] The above description is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
