Detailed Description

The present utility model will be further described with reference to the following specific embodiments, and it should be noted that, on the premise of no conflict, new embodiments may be formed by any combination of the embodiments or technical features described below.

In the description of the present utility model, it should be noted that, for the azimuth words such as terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the azimuth and positional relationships are based on the azimuth or positional relationships shown in the drawings, it is merely for convenience of describing the present utility model and simplifying the description, and it is not to be construed as limiting the specific scope of protection of the present utility model that the device or element referred to must have a specific azimuth configuration and operation.

It should be noted that the terms "first," "second," and the like in the description and in the claims are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

One aspect of the present utility model provides a spot pressure testing system, as shown in fig. 1, wherein a preferred embodiment includes a lamination tooling, a first detection device 200, a second detection device, and a control apparatus 700. Wherein the component 300 to be laminated can be placed in a lamination tool for lamination; the first detection device 200 is arranged in the lamination tool, and the first detection device 200 can detect the air pressure state in the lamination tool in the lamination process; the second detecting means may be provided on the upper surface of the component 300 to be laminated, so as to detect the pressure applied to the surface of the component 300 to be laminated during the lamination process; the control device 700 is disposed outside the lamination tool, and the control device 700 may be in signal connection with the second detection device to receive a pressure signal of the second detection device, so as to control a lamination state of the lamination tool according to a pressure condition of the surface of the component 300.

It should be noted that the first detecting device 200 is a detecting element in a conventional lamination tool, and the specific structure and working principle thereof are well known to those skilled in the art, and the first detecting device 200 is usually an air pressure sensor. The control device 700 may include a mobile device such as a computer or a cellular phone in which a driving program is installed.

It will be appreciated that the first detecting device 200 detects the air pressure value in Pa in the lamination tool that is the same as the air pressure value for laminating the component 300 during the lamination process; and the second sensing means senses the pressure applied to the surface of the assembly 300 during lamination in N.

When the assembly 300 is laminated using the conventional lamination method, the air pressure value P at which lamination is performed can be detected by the first detecting means 200; the average pressure received at the surface of the component 300 is calculated as P/S by the ratio of the air pressure value P to the surface area S of the component 300. Therefore, in the traditional lamination process, the lamination requirement can be met only by ensuring that the P/S is smaller than or equal to the set threshold J.

However, in the actual lamination process, the air pressure value at which lamination is performed is not uniform; if the first detecting device 200 is installed at a position with a low air pressure value, the detected value of the surface pressure of the component 300 is smaller than the actual value, and thus the component 300 may be subjected to a high pressure to generate hidden cracks; if the first detecting device 200 is installed at a position with a high air pressure value, the detected value of the surface pressure of the component 300 is greater than the actual value, and thus the pressure applied to the component 300 may not meet the lamination requirement.

Therefore, in this embodiment, the second detection device is disposed at a specific position on the surface of the component 300 based on the conventional lamination manner, and the stress conditions at different positions on the surface of the component 300 are detected by the second detection device, so that when the stress is over-limited at part of the positions of the component 300, the lamination state can be timely adjusted by the control device 700, and the lamination safety of the component 300 is further ensured, so that the occurrence of batch defective products of the component 300 is prevented.

In this embodiment, as shown in fig. 1 and 2, the second detecting device is disposed at the side and middle of the assembly 300. The quality of the laminate of the assembly 300 is improved by monitoring the stress conditions at the edges and the middle of the assembly 300.

It should be appreciated that the locations where the hidden cracks of the assembly 300 occur during the actual lamination operation are located substantially at the sides and middle of the assembly 300. Therefore, when the second detecting means is provided, it can be provided at positions where the assembly 300 is easily subjected to the hidden crack, that is, at the side and middle positions of the assembly 300.

Specifically, as shown in fig. 1 and 2, the second detection device includes a plurality of pressure sensors 400; wherein, part of the pressure sensors 400 may be disposed at intervals along the profile direction of the assembly 300, and the rest of the pressure sensors 400 may be disposed at intervals along the length direction in the middle of the assembly 300.

It should be appreciated that the specific number of pressure sensors 400 may be set according to actual needs during the actual design process. For example, as shown in fig. 1, in the present embodiment, the number of the pressure sensors 400 is twelve; wherein ten pressure sensors 400 may be disposed at intervals along the profile direction of the assembly 300, and the remaining two pressure sensors 400 may be disposed at intervals along the length direction in the middle of the assembly 300. The specific structure and operation of the pressure sensor 400 is well known to those skilled in the art and will not be described in detail herein.

In this embodiment, as shown in fig. 1 and 2, the lamination tool includes a housing 120 and a substrate 110, where the housing 120 and the substrate 110 are mutually covered to form a lamination cavity 100. The component 300 to be laminated may be laid on the substrate 110 within the lamination chamber 100 to be laminated; the first detecting means 200 is provided at the inner side of the housing 120 for detecting the air pressure in the lamination chamber 100.

In one embodiment of the present utility model, as shown in fig. 1 to 3, the spot pressure testing system further includes a buried wire tool 500 disposed at a side of the lamination tool; the buried wire tool 500 may cover the data wire 410 of the second inspection device.

It will be appreciated that since the laminator is internally sealed from vacuum during operation, the data from the pressure sensor 400 needs to be directed out through the data line 410. However, the number of the tested points is very large (twelve), and if the data lines 410 are randomly arranged, the use safety is affected. So that a buried wire tool 500 is designed to surround the periphery of the assembly 300, all the data wires 410 can be neatly placed in the buried wire tool 500, so that the data wires 410 are not deformed by extrusion and can be thermally insulated.

In this embodiment, as shown in fig. 3 and 4, a groove 111 is provided on a side portion of the substrate 110 along a contour direction, the wire embedding tool 500 is installed in the groove 111, and a depth of the groove 111 is greater than or equal to a height of the wire embedding tool 500; so that the buried wire tool 500 can be ensured not to interfere with the normal lamination process of the lamination tool.

It should be noted that, when the assembly 300 is laminated, the lamination tool needs to be kept sealed, and if the installation height of the wire embedding tool 500 is greater than the depth of the groove 111, sealing interference of the lamination tool may be caused, and feeding of the assembly 300 may be also interfered. Therefore, in designing the groove 111, it is necessary to ensure that the depth of the groove 111 is equal to or greater than the height of the buried line work 500.

In the present embodiment, since the four sides of the assembly 300 are provided with the pressure sensors 400; thus, the pressure sensors 400 on each side of the assembly 300 need to have data lines 410 leading out. Therefore, the wire embedding tool 500 may have an integral structure in a shape of a "mouth", or may have a sectional structure in a shape of multiple sections; to facilitate the design and installation of the buried wire tool 500, the buried wire tool 500 preferably adopts a segmented structure.

Specifically, the wire embedding tool 500 has multiple sections, each section of wire embedding tool 500 includes a pair of cover plates 510, and the inner side walls of the cover plates 510 are provided with wire embedding grooves 511; the two cover plates 510 can be symmetrically and tightly covered by the inner side walls, and then the two buried wire grooves 511 are matched with each other to form a buried wire cavity for placing the data wire 410. The cover plates 510 can be tightly covered by bonding, welding or buckling, and the specific mode can be selected by those skilled in the art according to actual needs.

In this embodiment, as shown in fig. 3, the outer profile of the cross section of the cover plate 510 is trapezoid or arc.

It should be understood that the cross section of the groove 111 is generally "U" -shaped, if the outer contour of the cross section of the cover 510 is also configured as "U" -shaped, that is, the cross section of the wire embedding tool 500 is rectangular; if the sectional size of the buried wire tool 500 is almost the same as that of the groove 111, it may be inconvenient to install and detach the buried wire tool 500. And after the outer profile of the cross section of the cover plate 510 is designed into a trapezoid or an arc shape, the size of the end of the cross section of the wire embedding tool 500 is obviously smaller than the width of the groove 111, so that the wire embedding tool 500 can be conveniently installed. And when the wire embedding tool 500 is disassembled, only one side of the wire embedding tool 500 needs to be pressed forcefully towards the bottom direction of the groove 111, so that the other side of the wire embedding tool 500 is tilted to be higher than the groove 111, and the wire embedding tool 500 can be disassembled conveniently.

In this embodiment, as shown in fig. 1, the point pressure testing system further includes an integration module 600, the data lines 410 of the plurality of pressure sensors 400 may be connected to an input terminal of the integration module 600, and the control device 700 may be connected to an output terminal of the integration module 600. So that the detection data of the plurality of pressure sensors 400 are integrated by the integration module 600 to be transmitted to the control device 700.

Specifically, in the present embodiment, the number of the pressure sensors 400 is twelve, and the input end of the integration module 600 has at least twelve connection holes so as to be connected with the signal output ends of all the pressure sensors 400. After the control device 700 is connected to the integration module 600, a driver installed in the control device 700 may be opened to acquire pressure data detected by the pressure sensor 400.

Another aspect of the utility model provides a laminator, wherein a preferred embodiment includes the point pressure test system described above.

The foregoing has outlined the basic principles, features, and advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model, which is defined by the appended claims.
