Description

Technical Field

[0001] The present invention relates to the technical field of laser detection, and in particular, to a laser detection device and a detection method for the size of an alcohol recovery device. Background Art

[0002] With the continuous improvement of the level of industrial automation and intelligence, the requirements for the performance and safety of alcohol recovery devices are also getting higher and higher. As an advanced measurement method, laser detection technology will play an increasingly important role in the production, installation, and maintenance of alcohol recovery devices.

[0003] Laser detection technology is a high-precision and non-contact measurement method, which is widely used in various industrial fields. In an alcohol recovery device, laser detection technology can be used to accurately measure the key dimensions of the device, such as the diameter, length, and other parameters of components such as distillation tanks, condensers, and buffer tanks. Through laser measurement, the manufacturing accuracy and assembly quality of these components can be ensured, thereby improving the overall performance and safety of the alcohol recovery device.

[0004] In the process of existing products performing size detection by laser, the fixing effect on the products is poor, resulting in low detection efficiency.

[0005] For example, a laser measurement device for measuring cylindrical products provided by the authorized announcement number CN114509007B. After the product collar is placed on the fixing column, the air cylinder is started. The air cylinder pushes the abutting block towards the abutting section through air pressure. The abutting block will abut against the spring piece to squeeze the inner wall of the product. When the operator needs to remove the product, as long as the air pressure of the air cylinder is withdrawn, the abutting block will slide towards the pneumatic section under the action of the spring, and the spring piece will contract. The product can be easily removed without the abutting of the spring piece; a positioning disk, a fixing table, a fixing column, a spring piece, and an abutting block are adopted, so as to achieve the effect of fixing the product on the placement table, and thus achieve the effect of quickly detecting the size of the rotary body product.

[0006] It has great drawbacks: When the existing device places a cylindrical product on the clamping device, the abutting block is cylindrical. When the lower end of the cylindrical product is sleeved on the abutting block, it is easy to hit the abutting block, resulting in a reduction in the placement efficiency, and during the impact process, the product will be damaged. Summary of the Invention

[0007] The embodiment of the present application provides a laser detection device and a detection method for the size of an alcohol recovery device, which solves the problem that in the prior art, when a cylindrical product is placed on a clamping device, the contact block is cylindrical. When the lower end of the cylindrical product is sleeved on the contact block, it is easy to hit the contact block, resulting in a decrease in the placing efficiency. Moreover, during the impact process, the product will be damaged. By changing the overall shape of the contact block into a conical shape, the contact area between the cylindrical product and the upper end of the contact block when entering is reduced, which can improve the placing efficiency of the cylindrical product. And the conical shape can provide a guiding effect on the cylindrical product, further improving the efficiency of placing the product, thereby improving the detection efficiency; reducing product damage. The conical contact block can guide the product into the fixed position more smoothly, reducing collisions and friction, thereby reducing the risk of product damage.

[0024] Example 1: As Figures 1 - 6 shown, a laser detection device for the size of an alcohol recovery device of the present application includes a support component 100 and a fixing component 200; The support component 100 includes a bottom plate 110; The fixing component 200 includes a fixing cylinder 210, a spring piece 220 and a contact block 230; The fixing cylinder 210 is fixed on the upper side of the bottom plate 110, the spring piece 220 is fixed on the upper side of the fixing cylinder 210, and the contact block 230 is fixed on the upper side of the spring piece 220; The contact block 230 is conical, the vertex of the contact block 230 is located at the upper end, and the axis of the contact block 230 is perpendicular to the ground; The spring piece 220 is used to contact the inner wall of the product to fix the position of the product. There are multiple spring pieces 220, and they are evenly spaced in a ring shape; The fixing cylinder 210 is a cylindrical shape that is penetrated up and down, and the axis of the fixing cylinder 210 is on the same straight line as the axis of the contact block 230; The spring piece 220 is located at the upper edge of the fixing cylinder 210 and the lower edge of the contact block 230; The support assembly 100 further includes a bracket 120, a motor 130, a rotating plate 140, a vertical laser profiler 150, an electric slide 160, a slider 170, a connecting plate 180, and an outer diameter measuring instrument 190; The bracket 120 is fixed on the upper side of the bottom plate 110, the motor 130 is fixed on the upper side of the bracket 120, the rotating plate 140 is fixed on the output end of the motor 130, and the vertical laser profiler 150 is fixed on the lower side of the rotating plate 140; When the motor 130 operates, it drives the entire rotating plate 140 to rotate and adjusts the irradiation position of the vertical laser profiler 150; The vertical laser profiler 150 is used to detect the vertical profile of the product; The rotation axis of the output end of the motor 130 is perpendicular to the ground, and the output end of the vertical laser profiler 150 faces the bottom plate 110; The electric slide 160 is fixed on one side of the bracket 120 close to the fixed cylinder 210. The slider 170 is slidably arranged on the electric slide 160. The connecting plate 180 is fixed on the slider 170. There are two outer diameter measuring instruments 190, which are symmetrically arranged on one side of the connecting plate 180; The electric slide 160 is used to adjust the irradiation position of the outer diameter measuring instrument 190. When the electric slide 160 operates, it drives the outer diameter measuring instrument 190 to rise or fall in height. The outer diameter measuring instrument 190 is used to detect the outer diameter of the product; The output ends of the two outer diameter measuring instruments 190 are arranged oppositely, and the fixed cylinder 210 is located between the two outer diameter measuring instruments 190; The length direction of the electric slide 160 is perpendicular to the ground, and the length direction of the electric slide 160 is the sliding direction of the slider 170; The fixing assembly 200 further includes a telescopic rod 240; The telescopic rod 240 is located inside the fixed cylinder 210. The lower end of the telescopic rod 240 is fixed on the bottom plate 110, and the upper end of the telescopic rod 240 is fixed on the lower side of the abutting block 230; The telescopic rod 240 is an electric telescopic rod; When the telescopic rod 240 retracts and drives the abutting block 230 to descend, the abutting block 230 presses the spring piece 220, causing the spring piece 220 to expand outwards and abut against the inner wall of the cylindrical product to be detected; The vertical laser profiler 150, the electric slide 160, the outer diameter measuring instrument 190, and the telescopic rod 240 are all prior arts and will not be elaborated here.

[0025] A detection method for a size laser detection device of an alcohol recovery device, using the above device, includes the following steps: S1: Set the cylindrical products to be dimensionally inspected on the fixed cylinder 210 and the abutting block 230; S2: Drive the abutting block 230 to descend by the retraction of the telescopic rod 240, so that the spring piece 220 expands outwards, abuts against the inner wall of the cylindrical product, and fixes the position of the cylindrical product; S3: During the process of expanding outwards by the spring piece 220 to abut against the cylindrical product, the cylindrical product not located at the detection center can be moved to the central position; S4: Drive the rotating plate 140 to rotate by the motor 130. Move the vertical laser profiler 150 to the upper end of the cylindrical product. Detect the cylindrical product through the vertical laser profiler 150, and detect whether the outer diameter of the cylindrical product meets the requirements through two outer diameter measuring instruments 190; S5: The outer diameter measuring instrument 190 can be driven to rise or fall by the electric slide table 160 to completely detect the surface of the cylindrical product; S6: After the detection is completed, the rotating plate 140 resets, and the abutting block 230 resets to cancel the limit on the cylindrical product. Then the cylindrical product can be taken down.

[0026] Compared with the prior art, by changing the whole of the abutting block 230 into a conical shape, the contact area between the cylindrical product and the upper end of the abutting block 230 when the cylindrical product enters is reduced, the feeding efficiency of the cylindrical product can be improved, and the conical shape can provide a guiding effect on the cylindrical product, further improving the feeding efficiency of the product, thereby improving the detection efficiency; reducing product damage, the conical abutting block 230 can guide the product into the fixed position more smoothly, reducing collision and friction, thereby reducing the risk of product damage.

[0027] Embodiment 2: When Embodiment 1 is used, by changing the whole of the abutting block 230 into a conical shape, the feeding efficiency is improved. However, when in use, the fixing effect of only abutting against the inner wall of the cylindrical product by the deformation of the spring piece 220 is poor, resulting in poor stability of the cylindrical product and low detection accuracy; and when moving the cylindrical product by abutting against the spring piece 220, in the case of a far offset position, the efficiency is poor, and at the same time the cylindrical product may tilt. Therefore, the solution of Embodiment 1 is improved as Figures 7 - 11 shown: The fixing assembly 200 further includes a contact ring 250; The contact ring 250 is annular, and the contact ring 250 is made of rubber; The contact ring 250 is fixed on the outer ring of the spring piece 220; When the telescopic rod 240 retracts and drives the contact block 230 to descend, the contact block 230 presses the spring piece 220, causing the spring piece 220 to expand outwards, so that the contact ring 250 contacts the inner wall of the cylindrical product to be detected; It further includes an auxiliary component 300, and the auxiliary component 300 includes a moving plate 310, a roller 320, a reset rope 330 and a winder 370; The moving plate 310 is a cylinder with a through hole in the up and down direction, and the moving plate 310 is sleeved on the outer circle of the fixed cylinder 210; In the initial state, the axis of the moving plate 310 and the axis of the fixed cylinder 210 are on the same straight line; There is a gap between the inner circle of the moving plate 310 and the outer circle of the fixed cylinder 210; There are multiple winders 370 and reset ropes 330 respectively. The number of winders 370 is the same as the number of reset ropes 330 and they correspond one by one; The winder 370 is fixed on the inner circle of the moving plate 310. The reset rope 330 is wound in the winder 370, and the end of the reset rope 330 away from the winder 370 is fixed on the outer circle of the fixed cylinder 210; The winder 370 is used to automatically wind the reset rope 330; The multiple winders 370 are evenly spaced in a ring; The roller 320 is fixed on the lower side of the moving plate 310. The roller 320 is placed on the upper side of the bottom plate 110, and the roller 320 is a universal wheel; The winder 370 is an automatic winder, which is a prior art and will not be elaborated here.

[0028] When in use, when the spring piece 220 is deformed by the retraction of the telescopic rod 240 and contacts the inner wall of the cylindrical product, the spring piece 220 contacts the external contact ring 250 and deforms together, so that the rubber contact ring 250 contacts the inner wall of the cylindrical product to fix the inner wall of the cylindrical product; when contacting a cylindrical product not located at the detection center, the cylindrical product will drive the moving plate 310 at the bottom to move together and pull the reset rope 330; after the detection is completed, and during the reset process of the spring piece 220, the deformed contact ring 250 has a certain elastic force, and the elastic force will assist the spring piece 220 to reset. When the cylindrical product is taken off the moving plate 310, the moving plate 310 will be reset by the winding force of the winder 370.

[0029] After deformation, the resistance ring 250 can fit on the inner wall of the cylindrical product, and the increased friction improves the fixing effect of the cylindrical product, thereby improving the detection efficiency and avoiding low stability during the detection process, which leads to the need for multiple detections and reduced accuracy; and the material used for contacting the inner wall of the cylindrical product is rubber, and during the contact process, it will not cause damage to the inner wall of the product, resulting in an impact on the quality of the product; and during the reset process of the deformation resistance ring 250, the elastic force will assist the spring sheet 220 in resetting, thereby improving the disassembly efficiency; and during the process of the resistance ring 250 resisting the cylindrical product, through cooperation with the movable plate 310, it can quickly make the cylindrical product that is not located at the detection center resist and move, thereby improving the fixing efficiency of the cylindrical product, thereby improving the detection efficiency of the product.

[0030] Embodiment 3: When the above embodiment is in use, the rubber-made friction ring 250 is fitted with the inner wall of the cylindrical product to improve the fixing effect. However, when in use, the deformation of the friction ring 250 and the inner wall of the cylindrical product are poorly fitted, so that the fixing effect of the device on the cylindrical product is poor; at the same time, the movement effect of the inner wall of the cylindrical product with the deformation position of the friction ring 250 and the spring sheet 220 is poor. Based on this, the solution of embodiment 2 is improved, such as Figures 12 - 14 As shown: The interior of the abutment ring 250 is hollow and has an airbag structure; The fixing assembly 200 further includes an air pump 260 and an air delivery pipe 270; The air pump 1 260 is fixed to the upper side of the bottom plate 110 , and the air pump 1 260 is located in the fixed cylinder 210 ; One end of the air delivery pipe 270 is connected to the output end of the air pump 1 260, and the end of the air delivery pipe 270 away from the air pump 1 260 is connected to the internal cavity of the abutment ring 250; When the air pump 1 260 is working, it can inflate or deflate the air to make the abutment ring 250 expand or contract.

[0031] A cylindrical product is placed on the movable plate 310. During the deformation of the spring sheet 220, the internal cavity of the resistance ring 250 is inflated by the air pump 260 to expand the resistance ring 250. The expanded resistance ring 250 fits the cylindrical product, and during the expansion of the resistance ring 250, it can quickly resist the cylindrical product that is not located at the center position of the device detection and move it to the center position of the detection quickly; the cylindrical product moves on the movable plate 310; and after the detection is completed and the cylindrical product is removed, the movable plate 310 is reset by pulling the reset rope 330 by the reel 370.

[0032] By expanding the contact ring 250, the contact area with the inner wall of the cylindrical product is increased, thereby improving the fixing effect of the product position; and during the expansion of the contact ring 250, through cooperation with the movable plate 310, the cylindrical product that is not located at the detection center can be quickly moved in friction, further improving the fixing efficiency of the cylindrical product, thereby improving the detection efficiency of the product; further reducing product damage, the expanded contact ring 250 can better protect the product surface and reduce damage caused by pressure and friction generated during the fixing process.

[0033] Example 4: When using Example 3, the expanded contact ring 250 contacts the cylindrical product, thereby improving its fixing effect. However, the device can also be improved to improve the fixing effect and efficiency of the cylindrical product. Moreover, when the cylindrical product is contacted by the expansion of the contact ring 250 and the deformation of the spring sheet 220 alone, the stability of the cylindrical product is poor and the contacted cylindrical product will tilt. Based on this, the solution of Example 3 is improved, such as Figures 15 - 18 As shown: The auxiliary assembly 300 further includes a fixing ring 340 , an abutting airbag 350 , and an air pump 2 360 ; The fixing ring 340 is a cylindrical body that is through from top to bottom. The fixing ring 340 is sleeved on the outer ring of the movable plate 310 and fixed to the upper side of the bottom plate 110. The axis of the fixing ring 340 and the axis of the fixing cylinder 210 are on the same straight line; A gap is left between the inner ring of the fixed ring 340 and the movable plate 310; The interference airbag 350 is annular, and the axis of the interference airbag 350 is on the same straight line as the axis of the fixing ring 340. The interference airbag 350 is fixed to the inner ring of the fixing ring 340. The second air pump 360 is fixed to the outer ring of the fixing ring 340, and the output end of the second air pump 360 is connected to the inside of the conflicting airbag 350; When the air pump 2 360 is working, the airbag 350 is expanded or retracted. The expanded airbag 350 can contact the outer wall of the product to fix the position of the product. The interference airbag 350 is located below the interference ring 250 , and after inflating, the interference airbag 350 is close to the lower end of the product to be detected.

[0034] When the cylindrical product is in use, the cylindrical product is placed between the fixed cylinder 210 and the fixed ring 340, and is placed on the movable plate 310. The spring sheet 220 is deformed and the resistance ring 250 expands to resist the inner wall of the cylindrical product to fix it and move its center position. At the same time, the air pump 260 works to deform the resistance airbag 350. The deformed resistance airbag 350 and the resistance ring 250 resist the cylindrical product together, so that it is quickly located at the center position of the test; and the position of the cylindrical product is fixed by the inner and outer double layers. When the cylindrical product is removed, the spring sheet 220 is reset, the resistance ring 250 retracts, and the resistance airbag 350 does not retract. After the cylindrical product is pulled out of the resistance airbag 350, the resistance airbag 350 continues to expand. The inflated resistance airbag 350 is located below the cylindrical product. After the cylindrical product slides down, it falls on the resistance airbag 350.

[0035] By expanding both the resistance airbag 350 and the resistance ring 250 together, the efficiency of moving cylindrical products to the detection center can be improved; and the resistance airbag 350 is located at the lower end of the resistance ring 250, which effectively avoids unstable movement and tilting due to the higher center of gravity during the process of resisting and moving cylindrical products; the fixing effect is improved, and the clamping method of the double airbag makes the product more stable, reducing the measurement error caused by product shaking or movement during the measurement process, and further improving the efficiency of detection; when taking off the cylindrical product, the resistance airbag 350 does not retract, and the resistance airbag 350 continues to expand. After the cylindrical product slides and falls, the cylindrical product can fall on the resistance airbag 350, and the resistance airbag 350 can play a buffering and protective role.

Various modifications and variations are readily apparent to those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
