[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] A wall thickness detection mechanism is provided, comprising:

Each gripper assembly is connected to the turntable and can clamp and release materials. The turntable is connected to the output end of the lifting and rotating drive, which can drive the turntable to rotate around its own axis and move in the vertical direction, so that the three gripper assemblies correspond to the material picking position, the wall thickness detection position, and the material releasing position, respectively.
[0007] A detection unit is used to detect the wall thickness of the material located at the wall thickness detection position.
[0008] Optionally, the detection unit includes a first sensor and a second sensor. When the material is located at the wall thickness detection position, the first sensor and the second sensor are located on the inner and outer sides of the material, respectively, to jointly detect the wall thickness of the material.
[0009] Optionally, the detection unit further includes a first protective shell, which is fitted onto the first sensor.

[0019] This invention provides a wall thickness detection mechanism, including a transport unit and a detection unit. The transport unit includes a turntable, a lifting and rotating drive, and at least three gripper assemblies. Each gripper assembly is connected to the turntable and can clamp and release material.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the drawings, not all of them.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0029] like Figures 1-3 As shown, the wall thickness detection mechanism in this embodiment includes a transport unit and a detection unit. The transport unit includes a turntable 1, a lifting and rotating drive 2, and at least three gripper assemblies 3. Each gripper assembly 3 is connected to the turntable 1 and can clamp and release material. The turntable 1 is connected to the output end of the lifting and rotating drive 2, which drives the turntable 1 to rotate around its own axis and move vertically, so that the three gripper assemblies 3 correspond to the material picking position, the wall thickness detection position, and the material placement position, respectively. The detection unit is used to detect the wall thickness of the material located at the wall thickness detection position.
[0030] Simultaneously, the first gripper group 3 of the three gripper groups 3 picks up the material from the upstream material pick-up position, the second gripper group 3 places the picked-up material at the wall thickness detection position to detect the wall thickness, and the third gripper group 3 places the detected material at the downstream material placement position. The unused gripper group 3 can also rotate to the material pick-up position to pick up material again. Compared to linear reciprocating transport, this wall thickness detection mechanism can achieve rotary transport, greatly improving transport efficiency and thus improving overall detection efficiency. Furthermore, this wall thickness detection mechanism uses only one lifting and rotating drive unit 2 to simultaneously control the operation of the three groups of materials, preventing inconsistent operating rhythms and ensuring stable detection.
[0031] Optionally, each gripper group 3 includes N pairs of grippers, and the detection unit has N wall thickness detection positions. The N pairs of grippers can move N materials to the N wall thickness detection positions respectively, where N is a positive integer greater than 1. That is, one gripper group 3 can hold N materials, and the wall thickness of N materials can be detected simultaneously, further improving detection efficiency. In this embodiment, N is 4, meaning each gripper group 3 has four pairs of grippers, each holding four materials, and the four materials are simultaneously transported to the four wall thickness detection positions for detection. Of course, in other embodiments, N can also be set to 2, 3, 5, 6, or a larger positive integer, which is not limited here.
[0032] Optionally, the transport unit also includes at least three gripping drive groups, each gripping drive group being connected to the turntable 1, and each gripper group 3 being configured with a gripping drive group, which is used to drive the grippers of the gripper group 3 to clamp and release the material.
[0033] Optionally, the transport unit also includes at least three connecting frames 8, each connecting frame 8 is distributed at intervals along the circumference of the turntable 1, and each connecting frame 8 is connected to the outer ring of the turntable 1, and at least three clamping drive units are connected to the at least three connecting frames 8 in a one-to-one correspondence.
[0034] In this embodiment, a total of four gripper assemblies 3 are provided, corresponding to four gripping drive assemblies and four connecting frames 8. The gripper assemblies 3, gripping drive assemblies, and connecting frames 8 are arranged in a one-to-one correspondence. Optionally, in this embodiment, the four connecting frames 8 are evenly spaced along the circumference of the turntable 1. That is, when the turntable 1 rotates 90°, the gripper assemblies 3 are transported to the next workstation. Along the rotation direction of the turntable 1, four workstations are arranged in sequence, namely the material pick-up position, the wall thickness detection position, and the material placement position. One of the workstations can be set as an empty workstation or as a workstation for placing materials that fail the inspection.
[0035] Optionally, in this embodiment, the gripper assemblies 3 are all located on the outside of the turntable 1, so that the gripper assemblies 3 can grip or put down materials when they descend.
[0036] Optionally, the clamping drive assembly is an air pump assembly 10, that is, one clamping drive assembly includes four air pumps, and the output ends of the four air pumps are respectively connected to four pairs of grippers to control the clamping and releasing actions of the grippers. The transport unit also includes a pneumatic slip ring 9, the rotating end of which is connected to the center of the turntable 1 so that the rotating end can rotate around its own axis with the turntable 1. The air pump assembly 10 is connected to the connector on the rotating end through an air pipe 11 to realize the air supply of the air pump during the rotation of the turntable 1.
[0037] Optionally, the transport unit also includes a support frame 12, the fixed end of the pneumatic slip ring 9 is connected to the support frame 12, the pneumatic slip ring 9 is located above the turntable 1, and the support frame 12 can support and fix the pneumatic slip ring 9.
[0038] Optionally, the lifting and rotating drive 2 is a cam lifting divider to ensure transportation accuracy and further improve detection efficiency.
[0039] like Figures 2-3 As shown, optionally, the detection unit includes a first sensor and a second sensor 4. When the material is located at the wall thickness detection position, the first sensor and the second sensor 4 are located on the inner and outer sides of the material, respectively, to jointly detect the wall thickness of the material. Optionally, the first sensor and the second sensor 4 measure the wall thickness of the material by laser ranging.
[0040] Optionally, in order to protect the first sensor, the detection unit further includes a first protective shell 5, which is fitted onto the first sensor. The material can be fitted onto the first protective shell 5, and the laser emitted by the first sensor can be emitted from the through hole of the first protective shell 5 onto the inner wall of the material.
[0041] Optionally, to protect the second sensor 4, the detection unit further includes a second protective shell 6, which is fitted onto the second sensor 4. The laser emitted by the second sensor 4 can be projected through the through-hole of the second protective shell 6 onto the outer wall of the material. Optionally, both the first protective shell 5 and the second protective shell 6 are cylindrical aluminum shells.
[0042] Optionally, the detection unit further includes a mounting bracket 7 for supporting the first protective shell 5 and the second protective shell 6. The first sensor is connected to the inner wall of the first protective shell 5, and the second sensor 4 is connected to the inner wall of the second protective shell 6.
[0043] Optionally, the detection unit also includes a standard distance block 13, which is only used when not in use. The standard distance block 13 is placed at the end of the first protective shell 5 and the second protective shell 6 that is not connected to the fixing bracket 7 to ensure that the distance between the first protective shell 5 and the second protective shell 6 meets the preset requirement. The standard distance block 13 needs to be removed when the detection begins.
[0044] Optionally, the wall thickness detection mechanism also includes a position sensor (not shown in the figure), which is used to detect whether there is material at the material pick-up location. Optionally, since the material pick-up location is located on a production line, the position sensor can be installed on the production line.
[0045] The following describes the working process of the wall thickness detection mechanism, using the steel shell 100 wall thickness detection as an example: When the position sensor on the production line senses that the steel shell 100 has reached the material picking position, the cam lifting divider is activated, driving the turntable 1 to rotate 90° counterclockwise to directly above the four steel shells 100. Then, when the cam lifting divider drives the turntable 1 to descend to a certain distance from the steel shell 100, the cylinder group on the first gripper group 3 is activated, and when the four grippers descend to the steel shell 100, they clamp the four steel shells 100 respectively. Then, the cam lifting divider drives the turntable 1 to rise and reset, rotating 90° counterclockwise so that the first gripper group 3 reaches directly above the detection unit. The turntable 1 descends until the four steel shells 100 are respectively inserted into the four first protective shells 5. At this time, the first sensor and the second sensor 4 measure the wall thickness of the steel shell 100 through laser ranging between them. After the test is completed, the cam lifting divider drives the turntable 1 to rise and reset, and continues to rotate counterclockwise by 90°. Then, the turntable 1 descends, the cylinder closes, and all four grippers release the steel shell 100, placing the steel shell 100 at the downstream material feeding position. It can be seen that the above only describes the working process of one gripper group 3; the other three gripper groups 3 can also perform the above working process simultaneously and alternately.
[0046] This wall thickness detection mechanism uses a cam-lifting divider as the power component, replacing the unidirectional paired motor, ensuring the synchronization of the machine. It has functions such as material feeding and automatic wall thickness detection. While saving design and assembly costs, it also greatly improves the detection efficiency and linkage of the machine.
[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
