Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, and particularly relates to a coating performance detection device. Background Art

[0002] Adhesion tests need to be performed on coatings such as powders and metals to detect the adhesion performance of the coatings. The pull-off method is a commonly used adhesion test method. During the test, glue is first evenly applied to the lower end of the stator, and then the lower end of the stator is vertically pressed onto the upper surface of the coating. After the glue is cured, the excess glue and the coating are manually scraped off circumferentially around the lower end of the stator using a scraper to prevent the excess glue and the coating around the stator from affecting the test results, and an adhesion test is performed using a detection device. Existing detection devices include a connection mechanism, a driving cylinder, and a tensile force sensor. The connection mechanism is installed at the lower end of the driving cylinder. The driving cylinder is connected to the upper end of the stator through the connection mechanism. The driving cylinder pulls up the stator through the connection mechanism, and the tensile force sensor detects the tensile force in real time. After the tensile force reaches the preset value, if the stator is not pulled up, it indicates that the adhesion of the coating is qualified. If the stator is pulled up before the tensile force reaches the preset value, it indicates that the adhesion of the coating is unqualified.

[0003] Existing detection devices do not have the function of scraping the coating and excess glue, and manual scraping is required. Manual scraping has unstable force and incomplete scraping, and is also time-consuming and laborious. Content of the Utility Model

[0004] In order to solve the shortcoming that existing detection devices do not have the function of scraping the coating and excess glue, the utility model proposes a detection device with the function of scraping the coating and excess glue.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] A coating performance detection device includes a bottom plate, a locking mechanism, and a detection head. The locking mechanism is used to lock a coating sample plate on the bottom plate. The detection head includes a cylinder body, a driving cylinder, a tensile force sensor, a connection head, and a stator. The cylinder body is arranged vertically. The driving cylinder is coaxially and fixedly connected to the upper end of the cylinder body. The driving cylinder includes a downward output shaft. The tensile force sensor is arranged on the output shaft. A receiving groove is arranged at the lower end of the output shaft. The upper end of the connection head is rotatably connected in the receiving groove and can move up and down. A limiting portion is arranged at the lower end of the output shaft to prevent the connection head from being pulled out of the receiving groove. The lower end of the connection head is threadedly connected to the upper end of the stator. The outer diameter of the lower end of the stator is adapted to the inner diameter of the cylinder body. An operation window is arranged on the side surface of the cylinder body. Scraper teeth are arranged along the circumference at the lower end of the cylinder body. The detection device further includes a rotation mechanism for driving the cylinder body to rotate coaxially, and a lifting mechanism for driving the cylinder body to move up and down.

[0007] Through the above arrangement, the rotation mechanism can drive the cylinder body to rotate, and the scraper teeth at the lower end of the cylinder body can scrape off the coating and excess glue on the outer periphery of the lower end of the stator. The scraping effect is better than manual scraping, and it is also more time-saving and labor-saving.

[0008] Furthermore, the detection head also includes a support base, a first guide rod, and a spring. The support base is coaxially arranged above the cylinder, and a vertically extending guide groove is provided on the lower side of the support base. The upper end of the first guide rod is slidably connected in the guide groove, and the lower end of the first guide rod is fixedly connected to the upper end of the cylinder. The spring is sleeved on the first guide rod, with its upper end fixedly connected to the support base and its lower end fixedly connected to the cylinder. The lifting mechanism drives the cylinder to move up and down through the support base.

[0009] With the above settings, the pressure of the lower end of the cylinder on the coating sample is gentler, preventing the scraping teeth at the lower end of the cylinder from excessively grinding the coating sample.

[0010] Furthermore, the lifting mechanism includes a second guide rod, a fixed plate, a lifting plate, and a lifting cylinder. The second guide rod is vertically fixedly connected to the upper side of the base plate, the fixed plate is horizontally fixedly connected to the upper end of the second guide rod, the lifting plate is located below the fixed plate and is slidably connected to the second guide rod, the lifting cylinder is vertically mounted on the fixed plate and connected to the lifting plate, the support seat is rotatably connected to the lower side of the lifting plate, and the rotating mechanism is mounted on the lifting plate and connected to the support seat.

[0011] With the above settings, the lifting cylinder extends and retracts to drive the lifting plate and the detection head to move up and down.

[0012] Furthermore, the rotating mechanism includes a drive gear, a driven gear, and a motor. The motor is fixedly connected to the lifting plate and connected to the drive gear. The driven gear has a ring structure and is fixedly connected to the outer circumference of the support base. The driven gear meshes with the drive gear.

[0013] With the above setup, the motor drives the cylinder to rotate via the drive gear and the driven gear.

[0014] Furthermore, an annular protrusion is fixedly connected to the upper side of the connector. The outer periphery of the annular protrusion fits against the wall of the receiving groove. The limiting part is a limiting flange fixedly connected to the lower end of the receiving groove. The limiting flange is located below the annular protrusion.

[0015] Furthermore, the locking mechanism includes a pressure plate and a locking cylinder. The pressure plate is arranged parallel above the base plate, and the locking cylinder is vertically fixed to the base plate and connected to the pressure plate. Attached Figure Description

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] like Figures 1 to 6 As shown, a coating performance testing device includes a base plate 3, a locking mechanism 4, and a testing head. The locking mechanism 4 is used to lock a coating sample 16 onto the base plate 3. The testing head includes a cylinder 5, a drive cylinder 6, a tension sensor 7, a connector 8, and a stator 9. The cylinder 5 is vertically arranged, and the drive cylinder 6 is coaxially fixedly connected to the upper end of the cylinder 5. The drive cylinder 6 includes a downward-facing output shaft, and the tension sensor 7 is mounted on the output shaft. A receiving groove 10 is provided at the lower end of the output shaft, and the upper end of the connector 8 rotates. The connector 8 is connected in the receiving groove 10 and can move up and down. The lower end of the output shaft is provided with a limit part 11 to prevent the connector 8 from being pulled out of the receiving groove 10. The lower end of the connector 8 is threaded to the upper end of the stator 9. The outer diameter of the lower end of the stator 9 is adapted to the inner diameter of the cylinder 5. The side of the cylinder 5 is provided with an operation window 12. The lower end of the cylinder 5 is provided with scraping teeth 13 along the circumference. The detection device also includes a rotating mechanism 14 that can drive the cylinder 5 to rotate coaxially, and a lifting mechanism 15 that can drive the cylinder 5 to move up and down.

[0024] With the above settings, the rotating mechanism 14 can drive the cylinder 5 to rotate, and the scraping teeth 13 at the lower end of the cylinder 5 can scrape off the coating 162 and excess adhesive 17 on the outer periphery of the lower end of the stator 9. The scraping effect is better than manual scraping, and it is also more time-saving and labor-saving.

[0025] Specifically, the base plate 3 is horizontally set, and multiple support legs are fixedly installed on the lower side of the base plate 3 to support it on the ground. The locking mechanism 4 horizontally locks the coating sample 16, on which the coating 162 to be tested is set on the upper side, onto the base plate 3. The coating sample 16 specifically includes the substrate 161 and the coating 162 applied to the upper side of the substrate 161. The cylinder 5 is basically a cylindrical structure, vertically set, open at the lower end and closed at the upper end. The rotating mechanism 14 can drive the cylinder 5 to rotate around its own axis, and the lifting mechanism 15 can drive the cylinder 5 to move up and down. The drive cylinder 6 is coaxial. The output shaft of the drive cylinder 6 is coaxially arranged in the cylinder 5 and fixedly connected to the upper end of the cylinder 5. The cross-section of the receiving groove 10 is circular and is coaxially arranged in the output shaft of the drive cylinder 6. The upper end of the connector 8 extends into the receiving groove 10 and can rotate freely around the axis of the receiving groove 10, and can also slide up and down along the axis of the receiving groove 10. The limiting part 11 limits the up and down movement range of the connector 8 to prevent the upper end of the connector 8 from leaving the receiving groove 10. The lower end of the stator 9 is circular and the lower end face of the stator 9 is glued to the upper side of the coating 162.

[0026] When using the testing device of this application, the coated sample 16 with the stator 9 bonded to it is horizontally locked onto the base plate 3 by the locking mechanism 4. The lifting mechanism 15 drives the testing head to move downward, and the lower end of the cylinder 5 is fastened to the lower end of the stator 9. The inner wall of the cylinder 5 is in contact with the outer periphery of the lower end of the cylinder 5. Figure 4 The finger is inserted into the cylinder 5 through the operating window 12, and the connector 8 is rotated. The connector 8 is rotated downwards, and the lower end of the connector 8 is tightened onto the upper end of the stator 9, as shown. Figure 5 The rotating mechanism 14 drives the cylinder 5 to rotate, and the lifting mechanism 15 drives the cylinder 5 to move downward. The scraping teeth 13 at the lower end of the cylinder 5 scrape off the excess glue 17 and coating 162 on the outer periphery of the lower end of the stator 9. The lifting mechanism 15 and the rotating mechanism 14 stop, and then the driving cylinder 6 runs, and the output shaft moves upward. The limiting part 11 applies an upward pulling force to the stator 9. The tension sensor 7 outputs the tension of the output shaft to the back end in real time. When the tension reaches the preset value, the stator 9 is still stuck to the coating sample 16, indicating that the adhesion performance of the coating 162 is qualified. Conversely, when the tension is not reached before the preset value, the stator 9 is pulled upward, indicating that the adhesion performance of the coating 162 is unqualified.

[0027] As one implementation, the detection head also includes a support base 18, a first guide rod 19, and a spring 20. The support base 18 is coaxially disposed above the cylinder 5. A vertically extending guide groove 21 is provided on the lower side of the support base 18. The upper end of the first guide rod 19 is slidably connected in the guide groove 21, and the lower end of the first guide rod 19 is fixedly connected to the upper end of the cylinder 5. The spring 20 is sleeved on the first guide rod 19. The upper end of the spring 20 is fixedly connected to the support base 18, and the lower end is fixedly connected to the cylinder 5. The lifting mechanism 15 drives the cylinder 5 to move up and down through the support base 18.

[0028] With the above settings, the pressure of the lower end of the cylinder 5 on the coating sample 16 is gentler, preventing the scraping teeth 13 at the lower end of the cylinder 5 from excessively polishing the coating sample 16.

[0029] The support base 18 of this application is basically cylindrical and is coaxially arranged above the cylinder 5. Four first guide rods 19 are specifically arranged evenly around the axis of the cylinder 5. The upper end of the first guide rod 19 is slidably connected in the guide groove 21, so that the cylinder 5 can move stably up and down below the support base 18. The support base 18 can drive the cylinder 5 to rotate synchronously through the first guide rods 19. When the lifting mechanism 15 drives the support base 18 to move up and down, the support base 18 can drive the cylinder 5 to move up and down synchronously through the spring 20. When the scraper tooth 13 at the lower end of the cylinder 5 contacts the coating sample 16 or the excess glue 17, the support base 18 continues to move downward, the spring 20 contracts, and the pressure at the lower end of the scraper tooth 13 gradually increases. The scraper tooth 13 scrapes away the excess glue 17 and coating 162 more gently, without causing excessive grinding, and it is easier to control the degree of scraping.

[0030] In one implementation, the lifting mechanism 15 includes a second guide rod 151, a fixed plate 152, a lifting plate 153, and a lifting cylinder 154. The second guide rod 151 is vertically fixedly connected to the upper side of the base plate 3. The fixed plate 152 is horizontally fixedly connected to the upper end of the second guide rod 151. The lifting plate 153 is disposed below the fixed plate 152 and is slidably connected to the second guide rod 151. The lifting cylinder 154 is vertically mounted on the fixed plate 152 and connected to the lifting plate 153. The support base 18 is rotatably connected to the lower side of the lifting plate 153. The rotating mechanism 14 is mounted on the lifting plate 153 and connected to the support base 18.

[0031] With the above settings, the lifting cylinder 154 extends and retracts to drive the lifting plate 153 and the detection head to move up and down.

[0032] Two second guide rods 151 are specifically provided, located at opposite ends on the upper side of the base plate 3. The second guide rods 151 are vertically arranged to ensure the stable up-and-down movement of the lifting plate 153. The fixed plate 152 is used to support the lifting cylinder 154. When the lifting cylinder 154 extends, the lifting plate 153 and the detection head on the lower side move downward synchronously. When the lifting cylinder 154 shortens, the lifting plate 153 and the detection head move upward synchronously.

[0033] As one implementation, the rotating mechanism 14 includes a drive gear 141, a driven gear 142 and a motor 143. The motor 143 is fixedly connected to the lifting plate 153 and connected to the drive gear 141. The driven gear 142 has a ring structure and is fixedly connected to the outer periphery of the support base 18. The driven gear 142 meshes with the drive gear 141.

[0034] With the above configuration, the motor 143 drives the cylinder 5 to rotate through the drive gear 141 and the driven gear 142.

[0035] Specifically, after the motor 143 drives the support base 18 to rotate via the drive gear 141, the support base 18 drives the cylinder 5 to rotate via the first guide rod 19.

[0036] As one implementation, an annular protrusion 22 is fixedly connected to the upper side of the connector 8. The outer periphery of the annular protrusion 22 fits against the groove wall of the receiving groove 10. The limiting part 11 is a limiting flange fixedly connected to the lower end of the receiving groove 10. The limiting flange is located below the annular protrusion 22.

[0037] The connector 8 of this application includes a connector body 81 and a connecting rod 82 vertically fixedly connected to the upper side of the connector body 81. An annular protrusion 22 is integrally formed on the outer periphery of the upper end of the connecting rod 82. The upper end of the connecting rod 82 and the annular protrusion 22 are disposed in the receiving groove 10. The outer periphery of the annular protrusion 22 of this application is circular and fits against the groove wall of the receiving groove 10. The annular protrusion 22 does not affect the rotation of the connector 8. The inner side of the limiting flange wraps around the connecting rod 82, so that the connector 8 can move up and down stably. A threaded hole is provided on the lower side of the connector body 81 for threaded connection with the upper end of the stator 9. When the drive cylinder 6 is running, the output shaft moves upward, and the limiting flange at the lower end of the output shaft pulls the stator 9 upward through the annular protrusion 22.

[0038] As one implementation, the locking mechanism 4 includes a pressure plate 41 and a locking cylinder 42. The pressure plate 41 is arranged parallel above the base plate 3, and the locking cylinder 42 is vertically fixedly connected to the base plate 3 and connected to the pressure plate 41.

[0039] Specifically, two locking cylinders 42 are provided in this application, located on the lower sides of both ends of the base plate 3. The locking cylinders 42 are connected to the pressure plates 41. When the locking cylinders 42 extend, the pressure plates 41 move upward; when the locking cylinders 42 retract, the pressure plates 41 move downward, thereby pressing the coated sample 16 firmly onto the base plate 3. A rubber pad may be provided on the lower side of the pressure plates 41 to improve the locking effect.

[0040] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
