[0022] See also Figures 1 to 3 , the utility model discloses a visual AI inspection station based on a collaborative robot, comprising: a bracket 1, a driving member 2, a platform 3 and a collaborative robot 4;

[0023] The driving member 2 is arranged on the bracket 1, and both ends of the platform 3 are respectively connected to the driving member 2. The collaborative robot 4 is arranged on one side of the platform 3, and a clamp 6 for installing the detection tool is provided at the end of the collaborative robot 4.

[0024] Specifically, the bracket 1 includes a base 101 and two vertical plates 102 arranged on the base 101 . Each vertical plate 102 is provided with a driving member 2 , and the platform 3 is sandwiched between the two vertical plates 102 .

[0025] Optionally, in this embodiment, the platform 3 and the driving member 2 are connected via a connecting plate 7 .

[0026] Optionally, the driving member 2 is a servo motor.

[0027] Optionally, in this embodiment, a connecting plate 7 is provided at each end of the platform 3, and the servo motor is connected to the connecting plate 7 at the corresponding end. Specifically, the connecting plate 7 is provided with a plurality of mounting holes, and the output end of the servo motor is provided with a plurality of structural holes. The servo motor and the connecting plate 7 are connected together by screws, bolts, or rivets. The servo motor can drive the connecting plate 7 and the platform 3 to rotate. Under the control of the controller, the servo motor can rotate to a variety of preset angles, for example, 30 degrees, 45 degrees, or 60 degrees, to facilitate the detection. Among them, the platform 3 is used to place the product 200 to be tested. The product 200 to be tested can be a seat frame but is not limited to a seat frame. It can also be other products, etc. Optionally, in this embodiment, the product 200 to be tested is placed on a jig, which is used to install and position the product 200 to be tested. The structure of the jig can refer to the existing technology and will not be described in detail here. Optionally, in this embodiment, the bracket 1, the drive member 2, and the platform 3 can be implemented using an existing positioner, which itself includes the bracket 1, the drive member 2, and the platform 3.

[0028] Optionally, the inspection tool is a go / no-go gauge head 51 or a laser rangefinder. For example, in this embodiment, the inspection tool is a go / no-go gauge head 51 (go / no-go fixed gauge). A go / no-go fixed gauge (GO-NO-GO FIXED GAUGES) is a type of gauge. It serves as a measurement standard and is used to inspect large quantities of products. In actual production, it is very tedious to measure large quantities of products one by one using measuring instruments (such as vernier calipers, micrometers, and other graduated measuring instruments). Qualified products have a measurement range, and products within this range are qualified. Therefore, people use go / no-go gauges for measurement. Go / no-go gauges are two measuring tools, one for the go gauge and the other for the no-go gauge. For example, an M6-7h thread go / no-go gauge has one end, a go gauge (T). If it can be smoothly screwed into the threaded hole being tested, it is qualified; otherwise, it is unqualified and requires rework (i.e., the hole is too small). Then, a no-go gauge (Z) is used. If it can be smoothly screwed into the threaded hole being tested 2.5 turns or more, it is unqualified; otherwise, it is qualified. At this time, the unqualified threaded holes should be scrapped and cannot be reworked. 2.5 turns is the national standard, and for export parts, only 1.5 turns (international standard) can be allowed. In short, if the go gauge passes the stop gauge but not the stop gauge, it is qualified. If neither the go gauge nor the stop gauge passes, or both the go gauge and the stop gauge pass, it is unqualified. For example, when inspecting the size of the hole, the stop end is made according to the upper limit of the allowable deviation of the aperture diameter, and the through end is made according to the lower limit of the allowable deviation of the aperture diameter. During the inspection, if the stop end can pass, it means that the aperture is too large, unqualified, and cannot be reprocessed; if the through end cannot pass, it means that the aperture is too small, also unqualified, but it can be made qualified through reprocessing.

[0029] Optionally, the clamp 6 is mounted on the end of the collaborative robot 4 through a mounting plate 9 . The clamp 6 includes a sleeve 61 and an elastic member 62 . The sleeve 61 is passed through the mounting plate 9 . Optionally, in this embodiment, the elastic member 62 is installed at one end of the sleeve 61, and a convex ring 63 is provided at one end of the sleeve 61. The two ends of the elastic member 62 are respectively abutted against the convex ring 63 and the plate surface of the mounting plate 9. One end of the sleeve 61 is provided with a clamping port for installing a detection tool. For example, in this embodiment, the clamping port is used to install the go / no-go gauge head 51, and a circular ring with a plum blossom-shaped opening is provided in the clamping port (not shown in the figure), and a pawl is provided on the outer side of the circular ring for realizing the installation and clamping of the go / no-go gauge head 51. For details, please refer to the ratchet wrench. A handle 64 is provided at the other end of the sleeve 61. Pressing the handle 64 downward can press the entire fixture 6 down, and the go / no-go gauge head 51 is pressed down for measurement. When the hand is released, the go / no-go gauge head 51 can be automatically separated from the product 200 under the action of the elastic member 62, such as a tension spring. Optionally, in another embodiment, the elastic member 62 is installed at the other end of the sleeve 61, and the clamping port is set at one end of the sleeve 61. In this case, the elastic member 62 is set as a compression spring to achieve the goal of pressing the handle 64 downward to press the entire clamp 6 down, and the go / no-go gauge head 51 is pressed down for measurement. When the hand is released, the go / no-go gauge head 51 can rise and automatically detach from the product 200 being measured under the action of the elastic member 62, such as a compression spring.

[0030] Optionally, a tool magazine 8 is provided on the driving member 2. The tool magazine 8 is a plate-shaped member, and a plurality of sockets 81 are provided on the plate-shaped member to place detection tools such as the go / no-go gauge head 51.

[0031] Furthermore, a PLC controller is also included, and the collaborative robot 4 and the driving element 2 are both electrically connected to the PLC controller. The PLC controller is used to realize electrical control of the inspection tool.

[0032] Optionally, in this embodiment, the platform 3 is a quadrilateral frame including a first side 31, a second side 32, a third side 33, and a fourth side 34 connected end to end. The first side 31 and the third side 33 are disposed opposite each other, and the second side 32 and the fourth side 34 are disposed opposite each other. Two mounting rods 14 are disposed on the first side 31 and the third side 33. Each mounting rod 14 is provided with a plurality of jacking drives 15, and each jacking drive 15 on the mounting rod 14 is provided with a jacking rod 16. Alternatively, in other embodiments, the platform 3 may be a plate-shaped member.

[0033] Preferably, a roller assembly 17 is provided above each lifting rod 16 to push the product 200 under test placed on the platform 3 off the platform 3. Specifically, in this embodiment, the top of the lifting rod 16 is provided with an empty slot, and the roller assembly 17 is installed in the slot. The top of the roller assembly 17 is higher than the top of the lifting rod 16, so that the product 200 under test only contacts the top of the roller assembly 17 and is smoothly pushed out.

[0034] Optionally, the lifting drive 15 may be a motor, a hydraulic cylinder or a pneumatic cylinder.

[0035] Preferably, a plurality of positioning posts 19 are provided on the platform 3 to achieve positioning of the product 200 to be tested placed on the platform 3. Specifically, in this embodiment, at least four positioning posts 19 are provided, which are respectively provided on the first side 31 and the third side 33.

[0036] Optionally, in this embodiment, a plurality of bases 20 are provided at the bottom of the base 101 for supporting the bracket 1 .

[0037] Optionally, the collaborative robot 4 adopts existing technology, such as a JAKA robot.

[0038] The flexible inspection tool with a collaborative robot provided by the present invention places the product 200 to be tested on the platform 3, which is positioned by the positioning column 19 and is located on the lifting rod 16. The lifting rod 16 can be in a low position during testing. On the one hand, the driving member 2 can drive the platform 3 to rotate to multiple different angles, so that the product 200 to be tested is rotated to the angle required for testing. The collaborative robot 4 moves with the testing tool to the target position aligned with the product 200 to be tested. When the product 200 to be tested needs to be removed after the test is completed, the lifting drive 15 drives the lifting rod 16 to rise, lifting the product 200 to exceed the height of the positioning column 19. The product 200 to be tested can be smoothly pushed out of the lifting rod 16, that is, out of the platform 3, by both hands to achieve unloading.

[0039] The present invention provides a flexible inspection fixture with a collaborative robot. The end of the collaborative robot 4 is equipped with a clamp 6 for installing a detection tool. During inspection, the corresponding detection tool is installed in the clamp 6, and then the collaborative robot 4 drives the detection tool to each position to be inspected of the product 200 to be inspected for inspection. After the inspection is completed, the detection tool is replaced to inspect other positions. The product 200 to be inspected only needs to be clamped once to complete the inspection of multiple positions and multiple items. The design of the inspection fixture can be reduced while ensuring the inspection of the product 200 to be inspected, such as the seat frame.
