DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 4 As shown, a filter aluminum can base strength detection device according to an embodiment of the present invention comprises a workbench 1, a conveyor belt 11 is arranged at the top of the workbench 1, and a plurality of support bars are evenly arranged on the surface of the conveyor belt 11; a first hydraulic cylinder 12 is arranged at the top of the workbench 1 and on one side of the conveyor belt 11, a connecting piece 13 is arranged at the end of the output end of the first hydraulic cylinder 12, a first suction cup 14 is arranged on the side of the connecting piece 13 away from the first hydraulic cylinder 12, and the first suction cup 14 is used to adsorb the bottom surface of the base of the aluminum can to be detected; a first hose 15 is arranged on the side of the first suction cup 14, and the first hose 15 is externally connected to a first pump body;

[0032] A fixing assembly for clamping and fixing the side of the aluminum can to be inspected is provided at the top of the workbench 1;

[0033] At present, it is necessary to test the strength of the die-cast base of the aluminum can of the filter during production. An ultrasonic detector is generally used for the specific test. The staff needs to operate independently during the test and install the ultrasonic probe to the monitoring position on the aluminum can. The operation is complicated and generally only sampling detection can be performed. It is not applicable to the strength test of the die-cast base of a large number of aluminum cans. The embodiment of the present invention provides a conveyor belt 11. During the test, the aluminum can to be tested is placed horizontally between the support bars on the conveyor belt 11, and then the conveyor belt 11 is controlled to rotate to convey the aluminum can to the test position; then the side of the aluminum can to be tested is clamped and fixed by a fixing component; then the first hydraulic cylinder 12 is started, and the first hydraulic cylinder 12 drives the first suction cup 14 to move to the base position of the aluminum can to be tested through the connecting piece 13, and stops when the opening of the first suction cup 14 is blocked by the base of the aluminum can, and then the first air pump connected to the first hose 15 is started, and the first air pump exhausts the first suction cup 14 through the first hose 15, so that the first suction cup 14 is adsorbed to the aluminum can. The surface of the base forms a vacuum adsorption on the surface of the aluminum can base, and then the first hydraulic cylinder 12 is controlled to contract, and the first suction cup 14 is used to pull the base of the aluminum can through force conduction, and the pulling force is controlled by controlling the output of the first hydraulic cylinder 12. When the strength of the die-casting of the aluminum can base reaches the standard, it is difficult for the first suction cup 14 to pull the aluminum can base off, and when the strength of the die-casting of the aluminum can base does not reach the standard, the first suction cup 14 will pull part of the aluminum can base off. It should be pointed out that the first suction cup 14 itself can be deformed, so that buffering is performed during the pulling process to avoid the base of the aluminum can with qualified die-casting quality from being forcibly pulled and damaged. After the inspection is completed, the adsorption and fixation of the aluminum can are released, and the conveyor belt 11 continues to drive the next aluminum can for inspection. The entire inspection process drives the aluminum can to move through the conveyor belt 11, and detects the strength of the die-casting of the aluminum can base through the first suction cup 14. Compared with the inspection through an ultrasonic detector, it has a high degree of automation and is suitable for large-scale inspection operations.

[0034] The connecting piece 13 is specifically a tension sensor; when the first suction cup 14 is working, it is adsorbed to the base of the aluminum can and pulls the base of the aluminum can. The tension sensor can detect the magnitude of the pulling force exerted by the first suction cup 14 on the base of the aluminum can; when the first suction cup 14 pulls the base of the aluminum can, the tension sensor detects the magnitude of the pulling force exerted by the first suction cup 14 on the base of the aluminum can. When the tension value reaches a specified value, it is determined that the strength of the die-casting of the aluminum can base is qualified, otherwise it is unqualified; and the specific value is transmitted to an external computer for retaining the detection data.

A clamping plate 24 is provided at the end of the output end of the third hydraulic cylinder 23; the clamping plate 24 is used to clamp and fix the side of the aluminum can to be tested; an inkjet gun 4 is provided at the end of the fixing frame 2, and the controller of the inkjet gun 4 communicates with the tension sensor through an electrical signal The controller of the inkjet gun 4 is used to control the opening and closing of the inkjet gun 4; the inkjet gun 4 sprays marking ink downward when working; when fixing the aluminum can to be tested, the second hydraulic cylinder 21 is started, and the second hydraulic cylinder 21 drives the fixing plate 22 to move to both sides of the aluminum can to be tested, and then the third hydraulic cylinder 23 is started, and the output end of the third hydraulic cylinder 23 drives the clamping plate 24 to clamp and fix the aluminum can to be tested; during the test, when the tension sensor determines that the strength of the die-casting of the aluminum can base is unqualified, it will send a start signal to the controller of the inkjet gun 4, so that the inkjet gun 4 sprays ink to the unqualified aluminum can, and marks the unqualified aluminum can, which is convenient for the staff to identify later.

[0036] like Figures 1 to 8As shown, a fourth hydraulic cylinder 3 is installed on the side of the vertical part of the fixing frame 2, and the output end of the fourth hydraulic cylinder 3 points to the top center position of the aluminum can located at the detection station; a receiving block 31 is provided at the output end of the fourth hydraulic cylinder 3, and a pair of cylinders 34 are symmetrically provided on both sides of the receiving block 31, and a piston 33 is slidably connected inside the cylinder 34; a push rod 32 is provided on the side of the piston 33 and passes through the outside of the cylinder 34, and the end of the push rod 32 located outside the cylinder 34 is connected to the receiving block 31; a pressure block 33 is provided on the side of the cylinder 34 away from the receiving block 31 7; A second hose 36 is connected to the side of the cylinder 34 facing the receiving block 31, and the second hose 36 is externally connected to a second pump body; a pressure relief valve 35 is connected to the side of the cylinder 34 and located on the side of the piston 33 facing the push rod 32; when the aluminum can moves to the inspection station, the third hydraulic cylinder 3 is started, and the third hydraulic cylinder 3 drives the receiving block 31 to move toward the inside of the aluminum can, and stops when it moves to the position aligned with the clamping plate 24, and then the second pump body connected to the second hose 36 is started, and the cylinder 34 is inflated through the second hose 36 in the second pump body, Since the piston 33 in the cylinder 34 is fixed to one side of the receiving block 31 by the push rod 32; therefore, under the action of the gas pressure, the cylinder 34 moves relative to the piston 33, and when the cylinder 34 moves, it drives the pressing block 37 to press against the inner wall of the aluminum can, and cooperates with the clamping plate 24 to clamp and squeeze the inner and outer parts of the same position of the aluminum can. In addition, a pressure relief valve 35 is provided on the side of the cylinder 34, and the pressure relief valve 35 can limit the gas pressure in the cylinder 34, and the squeezing force of the pressing block 37 on the inner wall of the aluminum can is provided by the gas pressure of the cylinder 34, so the gas pressure in the cylinder 34 is In order to prevent the pressing block 37 from squeezing the inner wall of the aluminum can, the pressure relief valve 34 can limit the squeezing force between the pressing block 37 and the inner wall of the aluminum can by limiting the air pressure in the cylinder 34, and fix the aluminum can in cooperation with the clamping of the clamping plate 24 on the outside of the aluminum can, that is, the inside of the aluminum can is supported by the pressing block 37 to prevent the aluminum can from being deformed by the clamping plate 24; at the same time, the same part of the aluminum can is synchronously clamped and fixed inside and outside, which effectively improves the fixing effect of the aluminum can; and the pressure relief valve 35 limits the squeezing force of the pressing block 37 on the inner wall of the aluminum can to prevent the inner wall of the aluminum can from being excessively squeezed and locally deformed and damaged.

[0037] A layer of rubber pad is arranged on the surface of the pressing block 37; the rubber pad buffers the process of the pressing block 37 squeezing the inner wall of the aluminum can, thereby protecting the inner wall of the aluminum can.

[0038] A pair of guide plates 5 are symmetrically arranged on the top of the workbench 1 based on the conveyor belt 11. The guide plates 5 include a parallel portion parallel to the conveying direction of the conveyor belt 11 and an inclined portion inclined to the conveying direction of the conveyor belt 11; the inclined portion is connected to the parallel portion; the spacing between the parallel portions of a pair of guide plates 5 is the same as the length of the aluminum can to be detected; the spacing between the inclined portions of a pair of guide plates 5 is greater than the length of the aluminum can to be detected;

[0039] When the aluminum cans are conveyed by the conveyor belt 11, both ends can be guided by the inclined parts of the guide plate 5, and then the position is adjusted and determined by the parallel part of the guide plate 5; when the aluminum cans are placed on the conveyor belt 11, in order to ensure that the position of the aluminum cans meets the detection requirements when they are moved to the detection station, it is necessary to preliminarily position the aluminum cans on the conveyor belt 11; therefore, the guide plate 5 is set, and when the placement position of the aluminum cans on the conveyor belt 11 deviates, the aluminum cans can be guided by the inclined parts of the guide plate 5 at both ends during the conveyance process of the conveyor belt 11, and then the position of the aluminum cans is determined by the parallel part of the guide plate 5; thereby ensuring that the aluminum cans can be accurately detected at the designated detection position by the conveyor belt 11, which is beneficial to the detection process.

[0040] A rotating belt 51 is sleeved on the surface of the receiving plate 5, and the rotating belt 51 can slide on the surface of the receiving plate 5; when the receiving plate 5 receives the aluminum can, the end of the aluminum can contacts the rotating belt 51 on the receiving plate 5, and the aluminum can can drive the rotating belt 51 to rotate on the surface of the receiving plate 5 through the friction between the aluminum can and the rotating belt 51, thereby reducing the resistance to the aluminum can and improving the smoothness of the movement of the aluminum can.

[0041] A baffle 62 is provided at the top of the workbench 1 and on one side of the fixed frame 2, a fifth hydraulic cylinder 6 is provided at the top of the workbench 1 and on one side of the first hydraulic cylinder 12, and an extrusion plate 61 is provided at the end of the output end of the fifth hydraulic cylinder 6; the extrusion plate 61 cooperates with the baffle 62 to squeeze the base of the aluminum can located at the next station after detection; after the aluminum can is detected, the base of the aluminum can is pulled outward by the first suction cup 14, which is easy to deform, and the deformation is difficult to recover after the pulling is released; based on this, the extrusion plate 61 is set; when the aluminum can is detected and moved to the next station, the fifth hydraulic cylinder 6 is started, and the fifth hydraulic cylinder 6 drives the extrusion plate 61 to squeeze the base of the aluminum can after detection, and the top of the aluminum can is supported by the baffle 62, the base of the aluminum can is pressed, and the pressing force is the same as the pulling force applied to the aluminum can during detection, so the base of the aluminum can is subjected to the same extrusion force after being subjected to the pulling force, thereby recovering the deformation caused by the pulling of the base of the aluminum can, thereby avoiding damage to the aluminum can during detection.

[0042] A sixth hydraulic cylinder 7 is arranged at the top of the workbench 1, and the output end of the sixth hydraulic cylinder 7 points to the top of the conveyor belt 11, and the sixth hydraulic cylinder 7 is connected to the tension sensor through an electrical signal; a receiving plate 71 is arranged at the top of the workbench 1 and at a position symmetrical to the conveyor belt 11 of the sixth hydraulic cylinder 7; the aluminum cans that fall off the conveyor belt 11 are driven by the sixth hydraulic cylinder 7 to be received by the receiving plate 71; when the tension sensor determines that the aluminum can is unqualified, an electrical signal is sent to the sixth hydraulic cylinder 7, the sixth hydraulic cylinder 7 is started, and the output end of the sixth hydraulic cylinder 7 pushes the unqualified aluminum can off the conveyor belt 11, and then it is received by the receiving plate 71, thereby realizing the function of automatically separating the unqualified aluminum cans and improving the automation effect; it should be pointed out that the tension sensor can send electrical signals to the controller of the inkjet gun 4 and the sixth hydraulic cylinder 7 respectively.

[0043] A sliding groove is provided at the top of the receiving plate 71; the aluminum can that falls onto the receiving plate 71 is partially embedded in the sliding groove; when the aluminum can slides on the receiving plate 71, the aluminum can is partially embedded in the sliding groove, so the moving direction of the aluminum can is restricted, and the aluminum can moves stably on the receiving plate 71.

[0044] During the inspection, the aluminum can to be inspected is placed horizontally between the support bars on the conveyor belt 11, and then the conveyor belt 11 is controlled to rotate to transport the aluminum can to be inspected to the inspection position; then the aluminum can to be inspected is clamped and fixed on the side by the fixing assembly; then the first hydraulic cylinder 12 is started, and the first hydraulic cylinder 12 drives the first suction cup 14 to move to the base position of the aluminum can to be inspected through the connecting piece 13, and stops when the opening of the first suction cup 14 is blocked by the base of the aluminum can, and then the first air pump connected to the first hose 15 is started, and the first air pump evacuates the first suction cup 14 through the first hose 15, so that the first suction cup 14 is adsorbed to the base of the aluminum can. The surface of the aluminum can base is vacuum-adsorbed, and then the first hydraulic cylinder 12 is controlled to contract, and the first suction cup 14 is used to pull the base of the aluminum can through force transmission, and the pulling force is controlled by controlling the output of the first hydraulic cylinder 12. When the strength of the die-casting of the aluminum can base reaches the standard, it is difficult for the first suction cup 14 to pull the aluminum can base off, and when the strength of the die-casting of the aluminum can base does not reach the standard, the first suction cup 14 will pull part of the aluminum can base off. It should be pointed out that the first suction cup 14 itself can be deformed, so that it can be buffered during the pulling process to avoid the base die-casting of qualified aluminum can base. The can base is damaged by forced pulling. After the inspection is completed, the adsorption and fixation of the aluminum can are released, and the conveyor belt 11 continues to drive the next aluminum can for inspection. The entire inspection process drives the aluminum can to move through the conveyor belt 11, and the first suction cup 14 is used to detect the strength of the die-casting of the aluminum can base. Compared with the inspection by the ultrasonic detector, it has a high degree of automation and is suitable for large-scale inspection operations; when the first suction cup 14 pulls the aluminum can base, the tension sensor detects the pulling force of the first suction cup 14 on the aluminum can base. When the tension value reaches the specified value, it is determined that the strength of the die-casting of the aluminum can base is qualified, otherwise it is unqualified; and the specific The numerical value is transmitted to an external computer for retaining the test data; when fixing the aluminum can to be tested, the second hydraulic cylinder 21 is started, and the second hydraulic cylinder 21 drives the fixing plate 22 to move to both sides of the aluminum can to be tested, and then the third hydraulic cylinder 23 is started, and the output end of the third hydraulic cylinder 23 drives the clamping plate 24 to clamp and fix the aluminum can to be tested; during the test, when the tension sensor determines that the strength of the die-casting of the aluminum can base is unqualified, it will send a start signal to the controller of the inkjet gun 4, so that the inkjet gun 4 sprays ink to the unqualified aluminum can, and marks the unqualified aluminum can, which is convenient for the staff to identify later.

[0045] When the aluminum can is moved to the inspection station, the third hydraulic cylinder 3 is started, and the third hydraulic cylinder 3 drives the receiving block 31 to move toward the inside of the aluminum can, and stops when it moves to the position aligned with the clamping plate 24, and then the second pump body connected to the second hose 36 is started, and the cylinder 34 is inflated through the second hose 36 in the second pump body. Since the piston 33 in the cylinder 34 is fixed to one side of the receiving block 31 through the push rod 32; therefore, under the action of air pressure, the cylinder 34 moves relative to the piston 33, and when the cylinder 34 moves, it drives the pressing block 37 to press against the inner wall of the aluminum can, and The inner and outer parts of the same position of the aluminum can are clamped and squeezed by the clamping plate 24, and the side of the cylinder 34 is connected to a pressure relief valve 35, which can limit the air pressure in the cylinder 34, and the extrusion force of the pressing block 37 on the inner wall of the aluminum can is provided by the air pressure in the cylinder 34, so the air pressure in the cylinder 34 is the extrusion force of the pressing block 37 on the inner wall of the aluminum can. Therefore, the pressure relief valve 34 can limit the extrusion force between the pressing block 37 and the inner wall of the aluminum can by limiting the air pressure in the cylinder 34, and the clamping plate 24 outside the aluminum can fixes the aluminum can, that is, the inside of the aluminum can is The pressing block 37 supports the aluminum can to prevent it from being deformed by the clamping plate 24; at the same time, the same part of the aluminum can is clamped and fixed synchronously inside and outside, which effectively improves the fixing effect of the aluminum can; and the pressure relief valve 35 limits the extrusion force of the pressing block 37 on the inner wall of the aluminum can to prevent the inner wall of the aluminum can from being excessively squeezed and locally deformed and damaged; when the aluminum can is placed on the conveyor belt 11, in order to ensure that the position of the aluminum can meets the inspection requirements when it moves to the inspection station, it is necessary to preliminarily position the aluminum can on the conveyor belt 11; therefore, a guide plate 5 is provided, and when the aluminum can is placed on the conveyor belt 11, the guide plate 5 is provided. When the position deviates, the two ends of the aluminum can can be guided by the inclined part of the receiving plate 5 during the conveying process of the conveyor belt 11, and then the position of the aluminum can is determined by the parallel part of the receiving plate 5; thereby ensuring that the aluminum can can be accurately detected at the designated detection position by the conveyor belt 11, which is beneficial to the detection process; when the receiving plate 5 receives the aluminum can, the end of the aluminum can contacts the rotating belt 51 on the receiving plate 5, and the aluminum can can drive the rotating belt 51 to rotate on the surface of the receiving plate 5 through the friction between the rotating belt 51 and the rotating belt 51, thereby reducing the resistance to the aluminum can and improving the smoothness of the movement of the aluminum can.

[0046] After the aluminum can is inspected, the base of the aluminum can is pulled outward by the first suction cup 14, which is easy to deform, and the deformation is difficult to recover after the pulling is released; based on this, an extrusion plate 61 is set; when the aluminum can is inspected and moved to the next station, the fifth hydraulic cylinder 6 is started, and the fifth hydraulic cylinder 6 drives the extrusion plate 61 to be squeezed onto the base of the aluminum can after inspection, and the top of the aluminum can is supported by the baffle 62, and the base of the aluminum can is pressed, and the pressing force is the same as the pulling force received by the aluminum can during inspection. Therefore, the base of the aluminum can is subjected to the same extrusion force after being pulled, thereby restoring the deformation caused by the pulling of the base of the aluminum can, thereby avoiding damage to the aluminum can during inspection; when the tension sensor determines that the aluminum can is not When qualified, an electrical signal is sent to the sixth hydraulic cylinder 7, the sixth hydraulic cylinder 7 is started, and the output end of the sixth hydraulic cylinder 7 pushes the unqualified aluminum can off the conveyor belt 11, and then it is received by the receiving plate 71, thereby realizing the function of automatically separating the unqualified aluminum cans and improving the automation effect; it should be pointed out that the tension sensor can send electrical signals to the controller of the inkjet gun 4 and the sixth hydraulic cylinder 7 respectively; the top of the receiving plate 71 is provided with a sliding groove; the aluminum can that falls on the receiving plate 71 is partially embedded in the sliding groove; when the aluminum can slides on the receiving plate 71, it is partially embedded in the sliding groove, so the moving direction of the aluminum can is restricted, and the aluminum can moves stably on the receiving plate 71.
