Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by detailed description of the invention.
Embodiment mono-
As Figure 1-3, it is a kind of device for sensor installation joint that the present embodiment proposes, comprise for the jiont treatment cover 1 of fixing and protection sensor connector and two for controlling the glue-line control cover 2 of glue-line shape and size, described jiont treatment cover 1 and glue-line control cover 2 are hollow structure, and bottom end opening; Two described glue-line control covers 2 are symmetricly set in the both sides of described jiont treatment cover 1 and are connected with described jiont treatment cover 1.Also comprise pressing structure, described pressing structure comprises the pressure plate 4, bolt 5 and the inner glue-line pad 6 that is provided with screwed hole that on it, are provided with screwed hole.
Wherein, the inwall size and dimension of described jiont treatment cover 1 and appearance and size and the shape of sensor connector are suitable.In the present embodiment, sensor connector is that cross sectional shape is hexagonal column construction, therefore jiont treatment cover 1 is also for cross sectional shape is hexagonal column construction, the height of jiont treatment cover 1 inwall is identical with the height of sensor connector, and sensor connector just in time can touch the internal face of the upper cover of jiont treatment cover 1.Under use state, described pressure plate 4 contacts with described glue-line control cover 2, described glue-line pad is fixed on structural member, can select the mode such as vacuum cup or magnetic that glue-line pad 6 is fixed on structural member, thereby described bolt 5 screw in the screwed hole of described glue-line pad 6 described glue-line control cover 2 is fixed on structural member through described pressure plate 4.Under not use state, can place separately.
Described glue-line control cover 2 in the present embodiment is wedge structure, the side contacting with described jiont treatment cover 1 is higher than the opposite side of described glue-line control cover 2, described glue-line control cover 2 contacts with sensor layer, shape and the described sensor layer of described glue-line control cover 2 are suitable, and described jiont treatment cover 1 is mutually concordant with the bottom of glue-line control cover 2.The reason that glue-line control cover 2 in the present embodiment is designed to wedge structure is that in order to coordinate this structure, the glue-line control cover 2 in the present embodiment is designed to wedge structure because the junction of sensor connector and intelligence sensor layer film is ramp structure.
Wherein, as one preferred embodiment, described jiont treatment cover 1 and glue-line control cover 2 structure that is formed in one.Described jiont treatment cover 1 and glue-line control cover 2 are made up of hard material.Jiont treatment cover 1 and glue-line control cover 2 structure that is formed in one produces gap after can effectively preventing from being connected by connected mode between the two, produces the bad problem of homogeneity.
Further, on the wall body of described jiont treatment cover 1 and glue-line control cover 2, be provided with the excessive glue hole 3 of overflowing for colloid.If the colloid in jiont treatment cover 1 and glue-line control cover 2 is too much, in the time that colloid reaches the position in the glue hole 3 of overflowing, colloid flows out from the glue hole 3 of overflowing, and can not affect thickness and the homogeneity of glue-line.
Use the device for sensor installation joint in the present embodiment, glue-line is carried out to THICKNESS CONTROL main method be: first on the position of wanting sensor installation joint, smear colloid, the colloid amount of smearing is more a little.Then, sensor connector is bonded on colloid, the cavity alignment sensor joint of jiont treatment cover 1 is also slowly moved down, sensor connector is contained in jiont treatment cover 1, in the time that joint is positioned on structural member edge, glue-line pad 6 is structurally installed, glue-line pad 6 is made up of magnet material, extract to be installed on structure fixed position and be convenient to, and the thickness of the glue-line retaining as required, adjustment bolt 5 enters into the number of turns of glue-line pad 6 glue-line control cover 2 is exerted pressure, and bondline thickness is finely tuned.
Further, on the inwall of described jiont treatment cover 1 and glue-line control cover 2, can be coated with one deck releasing agent.Therefore while using the device for sensor installation joint in the present embodiment to carry out the installation of sensor connector, can be after adjusting the thickness and width of glue-line, wait for after glue-line solidifies completely and again device being taken off.Certainly, also can before colloid solidifies, device be unloaded down, then utilize other mode fixation of sensor joint to wait for that colloid solidifies.
Use sensor connector erecting device in the utility model sensor connector can be arranged on fast accurately on position, installation effectiveness and accuracy is installed has obtained great raising; Owing to using jiont treatment cover and glue-line control cover to control glue-line, therefore, the thickness of glue-line, width and homogeneity are well controlled, and meanwhile, can also protect not bonded dose of sensor connector to adhere to; In use, the impact that is subject to glue-line inhomogeneities is lower for the sensor connector that sensor connector erecting device in use the utility model is installed, and the measurement result of sensor is more accurate.
Embodiment bis-
The difference of the present embodiment and embodiment mono-is, in the time being not suitable on structural member installing glue-line pad additional, the pressing structure of the device for sensor installation joint in the present embodiment does not adopt pressure plate, bolt and the inner glue-line pad that is provided with screwed hole.But, on the lateral wall of jiont treatment cover, installing weightening finish plate additional, the gravity of use device itself and the weight of weighted plate are controlled thickness and the homogeneity of glue-line.The mode of controlling bondline thickness and homogeneity in the present embodiment is simpler.
Structural member described in the application is parts or the member that will paste sensor connector, can be any position of wanting sensor installation joint.
Below described in conjunction with specific embodiments know-why of the present utility model, these are described is in order to explain principle of the present utility model, can not be interpreted as by any way the restriction to the utility model protection domain.Based on explain herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, within these modes all will fall into protection domain of the present utility model.
