Description

Technical Field

[0001] The utility model relates to a viscosity inspection device, in particular to a viscosity inspection device for an alkaline degreasing agent. Background Technique

[0002] Alkaline degreasing is the most commonly used process in electroplating pretreatment degreasing. Its main characteristics are that the degreasing agent is non-toxic, inexpensive, has a relatively good degreasing effect, is easy to manage, and the equipment is simple. It can be said that using alkaline degreasing is both cheap and easy to manage, so it is widely used. Its degreasing principle is to achieve the purpose of removing two types of oil stains by means of the saponification and emulsification of the solution. Saponification means the process in which grease reacts with the alkali in the degreasing agent to form soap. Common viscosity detection methods include methods such as using a rotational viscometer and a hydrometer for detection.

[0003] When using the method of detecting with a hydrometer, since there is a certain correlation between the viscosity of the degreasing agent and its specific gravity, therefore, the viscosity of the degreasing agent can be indirectly understood by measuring its specific gravity. The specific detection method is as follows: Specific gravity detection: Use a Baume hydrometer to measure the specific gravity of the original degreasing agent solution. A hydrometer is a tool used to measure the density of a liquid. By putting it into the liquid, according to the buoyancy of the liquid on the hydrometer, the specific gravity value of the liquid can be directly read out. The size of the specific gravity can reflect the viscosity of the liquid. The larger the specific gravity, the thicker the liquid and the relatively greater the viscosity; conversely, the smaller the specific gravity, the thinner the liquid and the relatively smaller the viscosity.

[0004] However, the common method of detecting with a hydrometer is that it is manually put into the degreasing agent to be detected for detection, so the detection efficiency is low, and it is impossible to ensure that the hydrometer is always located in the central area of the degreasing agent to be detected during the input process, so there will be a certain error in the detection result.

[0043] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0044] Please refer to Figures 1 to 8 , as an embodiment of the present utility model, the viscosity inspection device for the alkaline degreasing agent includes an inspection rack 1 and two columns 11 fixedly installed on the inspection rack 1, and the two columns 11 are symmetrically arranged on both sides of the inspection rack 1 in the horizontal direction; a lifting column 12 is slidably installed on the column 11, and the two lifting columns 12 are fixedly connected by a cross bar 13, and a connecting plate 14 is fixedly installed on the cross bar 13;

[0045] A conveying mechanism for intermittently conveying the material to be inspected is provided on the inspection rack 1;

[0046] A lifting mechanism connected to the lifting column 12 is further provided on the inspection rack 1; a hydrometer 15 is connected to the connecting plate 14;

[0047] The lifting mechanism can drive the lifting column 12 to slide inwards or outwards within the column 11, so as to drive the connecting plate 14 closer to or farther away from the inspection rack 1; and during the process of the connecting plate 14 approaching the inspection rack 1, the viscosity of the material to be inspected is inspected by the hydrometer 15, and during this process, the conveying mechanism does not operate; when the connecting plate 14 moves to the end of the stroke of moving away from the inspection rack 1, the conveying mechanism will operate to convey the next material to be inspected.

[0048] In this embodiment, when the conveying mechanism works, it will convey the alkaline degreasing agent to be detected directly below the hydrometer 15; then the conveying mechanism will pause working, and the lifting mechanism will take over the work. When the lifting mechanism operates, it will first drive the lifting column 12 to slide inwards within the column 11, so as to drive the connecting plate 14 closer to the alkaline degreasing agent to be detected on the conveying mechanism through the cross bar 13; during the approaching process, the hydrometer 15 will first contact the alkaline degreasing agent, and the connecting plate 14 will continue to approach the alkaline degreasing agent (never contacting the alkaline degreasing agent) until the end is formed; then, through the interaction between the buoyancy of the hydrometer 15 in the alkaline degreasing agent and its own gravity, part of the hydrometer 15 will be immersed in the alkaline degreasing agent, and when the forces of the two are balanced, the reading on the hydrometer 15 corresponding to the liquid level of the alkaline degreasing agent is the viscosity reading of the alkaline degreasing agent to be detected.

[0049] After recording the reading of the hydrometer 15, the lifting mechanism will drive the lifting column 12 to slide outwards within the column 11, so as to drive the connecting plate 14 away from the alkaline degreasing agent through the cross bar 13. During the process of the connecting plate 14 moving away, it will first drive the hydrometer 15 to separate from the alkaline degreasing agent, and then reset together with the hydrometer 15;

[0050] When the lifting mechanism drives the connecting plate 14 to move away from the alkaline degreasing agent to form the end, the lifting mechanism will keep the distance between the connecting plate 14 and the conveying mechanism unchanged, and the conveying mechanism will continue to work during this process to convey the inspected alkaline degreasing agent to the next position and convey the next untested alkaline degreasing agent directly below the hydrometer 15 for testing.

[0051] Through the mutual cooperation of the conveying mechanism and the lifting mechanism, the viscosity of the alkaline degreasing agent can be inspected orderly. By adopting the way of alternating cooperation of mechanical structures, the detection frequency is stabilized, the cooperation between detection and conveying is made more stable, and thus the detection efficiency is stabilized.

[0052] As a further solution of the present utility model, a motor 2 is fixedly installed on the inspection rack 1. A driving wheel 3 is fixedly connected to the output end of the motor 2. A driven wheel 4 cooperating with the driving wheel 3 is rotatably installed on the inspection rack 1. A first large pulley 401 is fixedly installed on the driven wheel 4. A first rotating shaft 5 is rotatably installed on the inspection rack 1. A first small pulley 501 is fixedly installed on the first rotating shaft 5. The first large pulley 401 and the first small pulley 501 are connected by a belt; a first bevel gear 6 is fixedly installed on the driving wheel 3. A second bevel gear 7 meshing with the first bevel gear 6 is rotatably installed on the inspection rack 1.

[0053] In this embodiment, the Maltese cross movement structure composed of the driving wheel 3 and the driven wheel 4 is adopted. Therefore, the motor 2 drives the driving wheel 3 to rotate, thereby driving the first bevel gear 6 to rotate, and driving the second bevel gear 7 to rotate through the meshing action; during one rotation of the driving wheel 3, the driven wheel 4 rotates a quarter of a turn, thereby driving the first large pulley 401 to rotate, and driving the first small pulley 501 to rotate through the belt, so as to drive the first rotating shaft 5 to rotate; the first rotating shaft 5 is connected to the conveying mechanism. When the first rotating shaft 5 rotates, the conveying mechanism can convey the alkaline degreasing agent; the second bevel gear 7 is connected to the lifting mechanism. When the second bevel gear 7 rotates one circle, the lifting mechanism will perform a complete set of actions.

[0054] As a further solution of the present utility model, the conveying mechanism includes a first belt roller 8 and a second belt roller 9 rotatably installed at both ends of the inspection rack 1. The first belt roller 8 and the second belt roller 9 are connected by a conveyor belt 10; a second small pulley 801 is fixedly installed on the first belt roller 8. A second large pulley 502 is fixedly installed on the first rotating shaft 5. The second small pulley 801 and the second large pulley 502 are connected by a belt.

[0055] In this embodiment, when the first rotating shaft 5 rotates, the second large pulley 502 also rotates synchronously, and drives the second small pulley 801 to rotate through the belt, thereby driving the first belt roller 8 to rotate; the rotating first belt roller 8 drives the second belt roller 9 and the conveyor belt 10 to rotate, so as to realize the conveying of the alkaline degreasing agent; by means of the conveyor belt 10, the alkaline degreasing agent can be moved smoothly through the conveyor belt 10, effectively reducing the deviation of the detection result caused by the shaking of the alkaline degreasing agent due to movement, and improving the accuracy of the inspection.

[0056] As a further solution of the present utility model, the size of the first large pulley 401 is larger than the size of the first small pulley 501; the size of the second large pulley 502 is larger than the size of the second small pulley 801.

[0057] In this embodiment, since the driving wheel 3 rotates one full circle while the driven wheel 4 rotates a quarter of a circle, a first-stage speed increase is achieved through the first large pulley 401 and the first small pulley 501, and a second-stage speed increase is achieved through the second large pulley 502 and the second small pulley 801, so as to control the stroke of one action of the conveying mechanism, thereby ensuring that the conveying mechanism can always move the alkaline degreasing agent directly below the hydrometer 15 each time, improving the accuracy of the inspection and avoiding damage to the hydrometer 15.

[0058] As a further solution of the present invention, the lifting mechanism includes a second rotating shaft 16 rotatably installed on the inspection rack 1. The second rotating shaft 16 is connected to the second bevel gear 7 by a belt. A chute 1601 is provided on the second rotating shaft 16. A slider 17 is sleeved on the second rotating shaft 16. A protruding column 1701 fixedly installed on the slider 17 is slidably engaged with the chute 1601. A connecting column 1201 fixedly installed on the slider 17 is fixedly connected to the lifting column 12.

[0059] In this embodiment, when the second bevel gear 7 rotates, it drives the second rotating shaft 16 to rotate through the belt, so that the chute 1601 also rotates synchronously. Through the sliding fit between the chute 1601 and the protruding column 1701, the slider 17 can be driven to slide in the length direction of the second rotating shaft 16, and the lifting column 12 can be driven to slide in or out of the vertical column 11 through the connecting column 1201. The cross bar 13 drives the connecting plate 14 to approach or move away from the alkaline degreasing agent, so that the hydrometer 15 can test the viscosity of the degreasing agent. During the test, the conveying mechanism does not work to prevent the contact time between the hydrometer 15 and the alkaline degreasing agent from being too short, resulting in errors in the test results, and also avoiding damage to the hydrometer 15. Through the mutual cooperation of the conveying mechanism and the lifting mechanism, the viscosity of the alkaline degreasing agent can be tested orderly. By adopting the alternating cooperation mode of the mechanical structure, the detection frequency is stabilized, and the cooperation between detection and conveying is more stable, thus stabilizing the detection efficiency.

[0060] As a further solution of the present invention, the chute 1601 consists of a first straight section, a second straight section, an inclined upward end and an inclined downward end; both ends of the first straight section are respectively communicated with the inclined upward end and the inclined downward section, both ends of the second straight section are respectively communicated with the other ends of the inclined upward end and the inclined downward section, the first straight section is located above the second straight section, and the two are mutually offset.

[0061] In this embodiment, when the protruding column 1701 slides in the first straight section and the second straight section of the sliding groove 1601, the slider 17 will not move. However, when the protruding column 1701 slides in the upwardly inclined section and the downwardly inclined section of the sliding groove 1601, the slider 17 will slide upward or downward in the length direction of the second rotating shaft 16, thereby driving the lifting column 12 to slide outward or inward in the column 11, so as to drive the connecting plate 14 to move away from or close to the alkaline degreasing agent.

[0062] In the initial position, the protruding column 1701 is located in the first straight section and at the connecting end point of the first straight section and the upwardly inclined section. During the cooperation between the driving wheel 3 and the driven wheel 4, the conveying mechanism will act to move the alkaline degreasing agent to directly below the hydrometer 15. At this time, the protruding column 1701 will slide in the first straight section, and the sliding direction is towards the downwardly inclined section. The position of the slider 17 will remain unchanged, so that the distance between the connecting plate 14 and the conveying mechanism remains unchanged. When the driving wheel 3 is disengaged from the driven wheel 4, the protruding column 1701 enters the downwardly inclined section. At this time, the conveying mechanism will stop acting to keep the position of the alkaline degreasing agent unchanged.

[0063] After that, the driving wheel 3 will continue to rotate, so that the protruding column 1701 slides in the downwardly inclined section of the sliding groove 1601, and the slider 17 will slide downward, thereby driving the connecting plate 14 to approach the alkaline degreasing agent. During the approaching process, the hydrometer 15 will first contact the alkaline degreasing agent, and the connecting plate 14 will continue to approach the alkaline degreasing agent (always not contacting the alkaline degreasing agent) until the end is formed.

[0064] As the driving wheel 3 rotates, the protruding column 1701 will enter the second straight section from the downwardly inclined section, so that the position of the connecting plate 14 will not change. Then, through the interaction between the buoyancy of the hydrometer 15 in the alkaline degreasing agent and its own gravity, part of the hydrometer 15 will be immersed in the alkaline degreasing agent. When the forces of the two are balanced, the reading on the hydrometer 15 corresponding to the liquid level of the alkaline degreasing agent is the viscosity reading of the alkaline degreasing agent to be detected.

[0065] After that, the protruding column 1701 will enter the upwardly inclined section from the second straight section and slide, so that the slider 17 slides upward, thereby driving the connecting plate 14 to move away from the alkaline degreasing agent. During the process of moving away, the connecting plate 14 will first drive the hydrometer 15 to separate from the alkaline degreasing agent, and then move away from the alkaline degreasing agent together with the hydrometer 15. When the protruding column 1701 enters the first straight section from the upwardly inclined section, the connecting plate 14 and the hydrometer 15 are reset. At this time, the driving wheel 3 and the driven wheel 4 start to cooperate to drive the conveying mechanism to convey the next alkaline degreasing agent to directly below the hydrometer 15.

[0066] Through the mutual cooperation of the conveying mechanism and the lifting mechanism, the viscosity of the alkaline degreasing agent can be inspected orderly. By adopting the alternating cooperation mode of the mechanical structure, the detection frequency is stabilized, the cooperation between detection and conveying is made more stable, and thus the detection efficiency is stabilized.

[0067] As a further solution of the present utility model, the support mechanism includes a sleeve 1401 fixedly installed on the connecting plate 14, and the sleeve 1401 surrounds the hydrometer 15; the inner diameter of the sleeve 1401 is larger than the outer diameter of the hydrometer 15, and a boss 1501 is fixedly installed on the hydrometer 15, and the diameter of the boss 1501 is larger than the inner diameter of the sleeve 1401.

[0068] In this embodiment, the connecting plate 14 will drive the hydrometer 15 to move synchronously through the mutual abutting cooperation of the sleeve 1401 and the boss 1501; after the hydrometer 15 contacts the alkaline degreasing agent, it will gradually sink into the alkaline degreasing agent, and due to the increase in buoyancy, the descending speed of the hydrometer 15 will be lower than that of the connecting plate 14, so the boss 1501 will be separated from the sleeve 1401. When the hydrometer 15 is in force balance, the position of the hydrometer 15 will no longer change, and the sleeve 1401 can ensure that the hydrometer 15 is always located in the central area of the alkaline degreasing agent. The reading on the hydrometer 15 corresponding to the liquid level of the alkaline degreasing agent is the viscosity reading of the alkaline degreasing agent to be detected.

[0069] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present utility model, all technical solutions that can implement the present utility model in other specific forms are included in the present utility model.
