Description

Technical Field

[0001] The utility model belongs to the field of detection technology, and specifically relates to a mechanical detection mechanism and a sagger detection device. Background Art

[0002] On the lithium battery production line, it is necessary to detect whether there are saggers in the roller kiln. There are two existing detection methods, namely photoelectric detection and ultrasonic detection.

[0003] Photoelectric cross-beam detection is when the sagger passes between the transmitter and the receiver and blocks the light, the photoelectric switch generates a switch signal. However, in the actual production process, the materials in the sagger will react at high temperatures to produce a large amount of tiny dust particles. Photoelectric cross-beam detection is easily affected by dust, causing the photoelectric switch to generate false signals.

[0004] Ultrasonic testing uses sound waves as a medium to perform non-contact, non-wear testing on the object being tested. The performance of ultrasonic testing is almost unaffected by any environmental conditions. However, since ultrasonic waves are arc-shaped sound waves, they are limited in some structures, and because they are electronic components, their temperature resistance cannot reach the temperature required by the roller kiln.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0044] Ginseng Figure 1 to Figure 4 As shown, the mechanical detection mechanism in a specific embodiment of the utility model includes:

[0045] Bottom plate 11;

[0046] The connecting rod 21 penetrates and is rotatably mounted on the bottom plate 11, and includes a first rod body located above the bottom plate 11, and a second rod body located below the bottom plate;

[0047] The roller 31 is rotatably mounted on the first rod;

[0048] The fixing plate 13 is fixedly installed below the bottom plate 11, and the fixing plate 13 is spaced apart from the second rod body;

[0049] One of the proximity switch 41 and the induction sheet 42 is fixedly mounted on the second rod, and the other is fixedly mounted on the fixing plate 13 .

[0050] In this embodiment, the first rod body of the connecting rod includes a first rod portion connected to the second rod body and a second rod portion away from the second rod body. The angle between the first rod portion and the second rod portion is an obtuse angle. The roller 31 is rotatably mounted on the end of the second rod portion.

[0051] Combination Figure 5 , Figure 6 As shown, a sealing flange 34 is sleeved on the second rod portion, a second mounting seat 33 is fixedly mounted on the sealing flange 34, a rotating shaft hole is opened on the second mounting seat 33, a second rotating shaft 35 passes through the rotating shaft hole and is mounted on the second mounting seat 33, and the roller 31 is rotatably mounted on the second rotating shaft 35.

[0053] Specifically, through the cooperation of the ceramic ring 32, the roller 31 and the second rotating shaft 35, when the object to be detected moves on the surface of the ceramic ring 32 of the mechanical detection mechanism, the roller 31 will rotate around the second rotating shaft 35, which can avoid the hard friction between the object to be detected and the ceramic ring 32 and damage to the ceramic ring 32 or the object to be detected. The second rotating shaft 35 converts sliding friction into rolling friction, which can increase the service life of the ceramic ring 32.

[0054] Furthermore, one end of the second rotating shaft 35 is fixed by a third retaining ring 38 .

[0055] Combination Figure 6 , Figure 7 As shown, a protective cover 71 is provided on the outside of the first rod body. The protective cover 71 can withstand high temperatures. The installation of the protective cover 71 can ensure that the mechanical detection mechanism in this embodiment can work in a high temperature environment.

[0056] Specifically, the protective cover 71 can prevent the components in the mechanical detection mechanism from being deformed due to high temperature. At the same time, the protective cover 71 can isolate the gas in the high temperature environment to avoid gas leakage. In addition, the protective cover 71 can also prevent dust from dripping and gathering in the mechanical detection mechanism and causing the mechanism to get stuck.

[0057] Combination Figure 7 , Figure 8 As shown, in this embodiment, a flange 12 is further installed on the bottom plate 11, and a sealing gasket 14 is installed on the flange 12. During actual use, the mechanical detection mechanism can be disassembled as a whole for maintenance or replacement.

[0058] Furthermore, in this embodiment, a first mounting seat 22 is fixedly mounted on the bottom plate 11 , and the second rod body of the connecting rod 21 is rotatably mounted on the first mounting seat 22 .

[0059] Specifically, a shaft hole is formed on the second rod body and the first mounting seat 22 , and the first shaft 23 passes through the shaft hole and is fixedly mounted on the first mounting seat 22 through a cotter pin 24 .

[0061] Furthermore, a fixing plate 13 is fixedly installed below the bottom plate 11 , and the fixing plate 13 is spaced apart from the second rod body.

[0062] Specifically, in this embodiment, the fixing plate 13 is fixedly mounted on the flange 12 .

[0063] Furthermore, a proximity switch 41 is fixedly mounted on the fixing plate 13 , and the proximity switch 41 is fixed by a hexagonal nut.

[0064] Furthermore, the induction sheet 42 inductively matched with the proximity switch 41 is fixedly mounted on the second rod body.

[0065] Furthermore, the mechanical detection mechanism in this embodiment also includes a reset spring 51, and a top screw 52 is installed on the fixed plate 13, and the top screw 52 is fixed by a hexagonal nut. The first end of the reset spring 51 is connected to the lower end of the second rod body, and the second end is connected to the top screw 52. The tension of the reset spring is adjusted by the hexagonal nut to adapt to detection in different forms.

[0066] Furthermore, the mechanical detection mechanism in this embodiment further includes a limiter 61 , which is fixedly mounted on the fixing plate 13 and disposed toward the second rod body. The limiter limits the movement range of the connecting rod to avoid erroneous movement.

[0067] Furthermore, the mechanical detection mechanism in this embodiment includes:

[0068] In the first state, the horizontal height of the roller is a first height, and the distance between the proximity switch 41 and the sensor sheet 42 is a first distance;

[0069] In the second state, the horizontal height of the roller is a second height, the distance between the proximity switch 41 and the sensor sheet 42 is a second distance, the first height is greater than the second height, and the second distance is greater than the first distance.

[0070] Specifically, the working principle of the mechanical detection mechanism in this embodiment is as follows:

[0071] 1. When there is no object to be detected on the mechanical detection mechanism, the mechanical detection mechanism is in the first state, the horizontal height of the roller 31 is the first height, and the distance between the proximity switch 41 and the sensor sheet 42 is the first distance. In the first state, the sensor sheet 42 is close to the proximity switch 41 and sends a signal that there is no object to be detected;

[0072] 2. When there is an object to be detected on the mechanical detection mechanism, the mechanical detection mechanism is in the second state, the horizontal height of the roller 31 is the second height, and the distance between the proximity switch 41 and the sensor sheet 42 is the second distance. In the second state, the sensor sheet 42 is away from the proximity switch 41, and a signal indicating that there is no object to be detected is sent.

[0073] Ginseng Fig. 9As shown, a sagger detection device in another embodiment of the utility model comprises the mechanical detection mechanism in the above embodiment, a roller kiln body and a plurality of rollers, wherein the mechanical detection mechanism is located between two adjacent rollers.

[0074] Furthermore, the sagger detection device in this embodiment includes:

[0075] In the first state, the level of the roller 31 is higher than the level of the roller 81;

[0076] In the second state, the horizontal height of the roller 31 is equal to the horizontal height of the roller 81 .

[0077] Specifically, the working principle of the sagger detection device in this embodiment is as follows:

[0078] 1. When the sagger 91 has not passed through the mechanical detection mechanism, the sagger detection device is in the first state, the horizontal height of the roller 31 is higher than the horizontal height of the roller 81, and the sensor sheet 42 is close to the proximity switch 41, and a signal indicating that there is no sagger is sent;

[0079] 2. When the sagger 91 moves to the mechanical detection mechanism through the roller 81, the gravity of the sagger 91 causes the roller 31 to press down, and the sagger detection device is in the second state, and the horizontal height of the roller 31 is equal to the horizontal height of the roller 81. In this state, the downward force of the roller 31 passes through the first rotating shaft 23, causing the connecting rod to rotate in a direction away from the fixed plate 13, so that the induction sheet 42 fixedly mounted on the connecting rod moves away from the proximity switch 41, and a signal of the presence of the sagger is sent;

[0080] 3. After the sagger 91 passes through the mechanical detection mechanism, the roller 31 loses pressure, and the connecting rod rotates toward the fixed plate 13 under the action of the reset spring 51, the roller 31 rises, and the mechanical detection mechanism returns to the first state. The horizontal height of the roller 31 is higher than the horizontal height of the roller 81, and the sensor sheet 42 approaches the proximity switch 41, sending a signal that there is no sagger.

[0081] It can be seen from the above technical solution that the utility model has the following beneficial effects:

[0082] The mechanical detection mechanism of the utility model has a simple structure principle and high reliability. By adding a protective cover, it can be used in high temperature and high dust conditions, and its application field is wider. At the same time, the mechanical detection mechanism of the utility model is easy to install and disassemble as a whole, which can greatly shorten the maintenance time and improve the maintenance efficiency.

[0083] The sagger detection device of the utility model can realize the individual detection of each row of saggers in the case of multiple rows of saggers.

[0084] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
