[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides an embodiment of an automatic quality inspection device for adhesive used in steel plant dust removal pellets. It includes a workbench 1 with support legs 11 at its bottom. Two upward-protruding limiting plates 14 are welded to the top of the workbench 1. A pressing assembly is rotatably connected between the two limiting plates 14. The pressing assembly includes a rotating rod 21. A pressure head 63 for applying pressure to the pellets is rotatably connected to one end of the rotating rod 21. A crack detection assembly is located above one end of the rotating rod 21. A placement basin 13 for placing the pellets is located below the pressure head 63 at the top of the workbench 1. A balance adjustment assembly 6 is also provided on the rotating rod 21. Pressure transmission and amplification are achieved through the lever principle. The limiting plates 14 ensure the stability of the pressing assembly's rotation. The workbench 1 integrates support, installation, and positioning functions, providing a stable and reliable foundation platform for the entire quality inspection process.

[0019] Please see Figure 1-5 A further solution based on this embodiment is as follows: The balance adjustment component 6 includes a mounting plate 22 protruding from the rotating rod 21. An electric cylinder 4 is mounted on the mounting plate 22. The output end of the electric cylinder 4 is engaged with a counterweight 61. The electric cylinder 4 includes a servo motor 41 that drives the output end to move. By precisely driving the counterweight 61 along the rotating rod 21 through the electric cylinder 4, the automatic and precise adjustment of the loading force is realized. The servo motor 41 ensures the smoothness and controllability of the movement, significantly improving the efficiency and repeatability of the test and avoiding errors caused by manual operation.

[0020] Please see Figure 1-5A further solution based on this embodiment is as follows: the counterweight 61 can move toward the side where the pressure head 63 is provided. The counterweight 61 is provided with a second vertical rod 611, and a counterweight ring block 25 is sleeved on the outer diameter of the second vertical rod 611. Through the cooperative design of the second vertical rod 611 and the counterweight ring block 25, the total mass of the counterweight 61 can be finely adjusted, thereby realizing the fine calibration of the applied pressure, enhancing the flexibility and testing accuracy of the device, and adapting to the testing needs of pellets of different strengths.

[0021] Please see Figure 1-4 A further solution based on this embodiment is as follows: a vertical rod 211 protruding upward is provided on the side of the rotating rod 21 away from the pressure head 63, and a counterweight ring 25 is sleeved on the outer diameter of the vertical rod 211. By setting the vertical rod 211 and sleeved with the counterweight ring 25 on the rotating rod 21, the initial balance adjustment of the rotating rod 21 can be performed before the test, eliminating the deviation caused by the weight of the rotating rod 21 and other factors, and ensuring the accuracy of pressure measurement.

[0022] Please see Figure 1-4 A further solution based on this embodiment is as follows: the bottom of the rotating rod 21 is provided with a downwardly protruding fixing block 24, and the pressure head 63 includes two upwardly protruding protrusions 631. The fixing block 24 is rotatably connected between the two protrusions 631. Through the rotatable connection structure, the pressure head 63 can ensure that the bottom of the pressure head 63 is parallel to the top of the workbench 1, ensuring that the pressure is applied vertically downward, avoiding measurement errors or abnormal breakage of the ball due to off-center loading. At the same time, the connection structure is simple and reliable, and easy to maintain.

[0023] Please see Figure 2-5 A further solution based on this embodiment is as follows: The rupture detection component includes a transmitter 32 fixedly mounted on the rotating rod 21 and a receiver 31 corresponding to the position of the transmitter 32. The receiver 31 is connected to the rotating rod 21 through an elastic element. By adopting a non-contact photoelectric detection method, the receiver 31 is connected to the elastic element. The rupture point is determined by the interruption of the light path caused by the slight vibration or displacement of the rotating rod 21 at the moment of pellet rupture. The response speed is fast and the detection sensitivity is high.

[0024] Please see Figure 2-5A further embodiment of this solution is as follows: the elastic element includes a spring 53, the breakage detection assembly includes a column 52 that passes through the rotating rod 21, a baffle 51 is integrally formed at the bottom of the column 52 corresponding to the bottom of the rotating rod 21, an L-shaped plate 54 is installed at the top of the column 52 corresponding to the top of the rotating rod 21, a receiver 31 is attached to the L-shaped plate 54, a shim 23 is provided on the rotating rod 21, a transmitter 32 is installed on the shim 23, the spring 53 is sleeved on the column 52 in the area between the rotating rod 21 and the L-shaped plate 54, the receiver 31 is indirectly connected to the rotating rod 21 through the column 52, the spring 53 provides elasticity, the baffle 51 acts as a limit, which can limit the spring 53 from driving the L-shaped plate 54 to move excessively upward, and the shim 23 ensures that the transmitter 32 and the receiver 31 are precisely aligned.

[0025] Please see Figure 2-5 A further solution based on this embodiment is as follows: a temporary storage box 12 is provided on the workbench 1, which can temporarily store the spheres to be inspected. A robotic arm that automatically grabs the spheres in the temporary storage box 12 is provided on one side of the workbench 1. The temporary storage box 12 facilitates the orderly storage of the spheres to be tested. With the help of the robotic arm, the feeding can be automated, greatly reducing manual intervention and improving the automation level of the entire quality inspection process.

[0026] Working principle: First, the system is initialized. The initial balance of the rotating rod 21 is adjusted by placing a counterweight ring 25 on the vertical rod 211 at the end of the rotating rod 21 furthest from the pressure head 63, ensuring precise alignment between the transmitter 32 and receiver 31. Then, the robotic arm picks up the sphere to be tested from the temporary storage box 12 and places it directly below the pressure head 63 in the placement basin 13. The control system activates the electric cylinder 4, whose servo motor 41 drives the counterweight 61 to move along the rotating rod 21 to apply increasing pressure. The vertical rod 611 on the counterweight 61 can be adjusted by adding or removing the counterweight ring 25 to achieve fine adjustment of the loading mass. During loading, the light beam emitted by the transmitter 32, fixed on the raised block 23, is received by the receiver 31 elastically connected to the rotating rod 21, maintaining optical continuity. When the sphere breaks instantaneously at its pressure limit, the rotating rod 21 experiences a rapid, minute displacement due to force imbalance. This causes the elastically connected receiver 31 to lag behind the movement of the rotating rod 21 due to inertia, resulting in a relative displacement and interruption of the optical path. The control system then uses this signal... The critical point of rupture is accurately captured, and the compressive strength value is calculated by combining the position and mass of the counterweight 61 and the lever principle. After the test is completed, the electric cylinder 4 controls the counterweight 61 to reset. There is also a robotic arm that can grab the vacuum cleaner bellows and clean and suck away the crushed ball residue from the placement basin 13. Then the robotic arm grabs the next ball for cyclic testing, thereby realizing fully automatic continuous operation of feeding, detection and cleaning. The electric cylinder 4, servo motor 41, receiver 31, transmitter 32, robotic arm grabbing the ball and robotic arm grabbing the bellows are existing technologies. The wiring method, electrical control principle and control method are also known to those skilled in the art. The column 52 can be a thin metal rod with elasticity. The control system includes a PLC, which can determine the extension distance of the output end of the electric cylinder 4 by the number of rotations of the servo motor 41. The rotating connection is existing technology. The rotating connection can be a rotating shaft passing through the rotating hole. The rotating shaft has a groove and a retaining spring is sleeved in the groove. The rotating rod 21 is equivalent to a lever.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
