Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a non-contact height measuring device. Background Art

[0002] During chip processing, if the height of the epoxy resin glue on the device on the chip board is too high, it will affect the module assembly and insulation performance, etc., so it is necessary to control the glue height of the device on the board. The traditional way to measure the glue height is through the height gauge contact test. First, place the board on the marble platform under the height gauge. Each time the glue height is measured, the height gauge needs to be zeroed on the surface of the device body, and then the probe moves to the highest point of the glue to measure the reading.

[0003] However, since the probe has an impact on the device when it descends during the entire measurement process, and the probe is prone to slide to other places when it moves to the highest point of glue dispensing, each board needs to measure 8 glue dispensing heights, that is, 8 times of zeroing. The risk of damage to the device cannot be ruled out during this operation, and there are disadvantages of low production efficiency and difficulty in ensuring quality.

[0004] Therefore, how to improve chip production quality is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0027] The core of the utility model is to provide a non-contact height measuring device to improve the chip production quality.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0029] Please refer to Figures 1 to 3 .

[0030] In a specific embodiment, the non-contact height measurement device provided by the specific embodiment of the utility model includes a carrier module 1, an instrument motion module 4, a laser displacement measurement module and a display module, and the carrier module 1 has a device positioning space for accommodating the device to be detected. By setting the device positioning space, the product whose device dispensing height needs to be measured is placed on the carrier module 1 and fixed to achieve stable measurement. Specifically, the product is placed on the carrier module 1, and the position remains unchanged during the process of measuring the dispensing height of the product, protecting the product from being bumped and ensuring the accuracy of the measurement.

[0031] The device positioning space may be located in a groove adapted to the edge of the device, and its specific shape is determined according to the shape of the device, or the device positioning space may be composed of a plurality of limiting pillars attached to the side wall of the device.

[0032] The instrument motion module 4 has a measuring end 6 that moves along the dimension measurement direction. For example, when measuring height, the measuring end 6 moves vertically up and down. Specifically, the measuring end 6 can be driven up and down by a telescopic rod, or by a motor driving a worm gear to achieve the lifting of the measuring end 6. The laser displacement measurement module includes a laser sensor 3 installed at the measuring end 6. When used, the laser sensor 3 is programmed according to the path to be measured and then moves for measurement.

[0033] The display module is connected to the laser position measurement module to display the measurement result. Specifically, the limit module can be a computer set at a remote end.

[0034] Alternatively, the display module has an amplifier screen connected to the laser displacement measurement module to display the measurement results. The sensor using laser technology for measurement can accurately measure the position, displacement and other changes of the measured object without contact. When in use, the measurement results of the laser displacement sensor are displayed on the amplifier screen for reading through the sensor cable, reducing the possibility of reading errors.

[0035] From the above description, it can be seen that in the non-contact height measurement device provided in the specific embodiment of the present application, the laser sensor 3 is driven to rise and fall by the instrument motion module 4 to measure the dispensing height. During the entire measurement process, no direct force is applied to the dispensing position, thereby detecting damage to the chip during the measurement process. Therefore, the non-contact height measurement device provided in the present application improves the production quality of the chip.

Specifically, the instrument motion module 4 is provided with a turntable, which is rotatably mounted on the equipment platform 2, and the measuring end 6 is mounted on the turntable through a lifting device.

[0039] In order to facilitate the disassembly of the vehicle module 1, preferably, the vehicle module 1 is detachably connected to the equipment platform 2. Specifically, the vehicle module 1 is mounted on the equipment platform 2 by means of buckles or threaded fasteners, so as to facilitate the replacement of vehicle modules 1 of different specifications.

[0040] The carrier module 1 is an insulating module. Specifically, the carrier module 1 can be a plastic part. Preferably, the carrier module 1 is made of black fiberglass. The black fiberglass material has excellent anti-static performance, and the carrier surface is smooth and flat, heat-resistant and moisture-resistant, not easy to deform, and has excellent mechanical properties; at the same time, it is not easy to scratch the product, which can protect the board and device and avoid static electricity.

[0041] In order to improve the measurement efficiency, it is preferred that a plurality of laser sensors 3 are provided, and the laser sensors 3 are connected one-to-one with the measuring end 6, wherein two, three, etc. laser sensors 3 can be provided, or the same number of laser sensors 3 can be provided according to the number of product test points. Specifically, by providing a plurality of laser sensors 3, the non-contact height measurement device can test the dimensions of multiple position points at the same time.

[0042] In a specific implementation, the laser sensor 3 includes a laser transmitter and a laser receiver which is arranged at the same height as the laser transmitter and corresponds to the laser receiver one by one. Specifically, the dimension measurement is achieved by the cooperation between the laser transmitter and the laser receiver.

[0043] The non-contact height measuring device further comprises a visual camera 5, which is used to locate the height measurement position when measuring the height. Specifically, the visual camera 5 is used to locate the height measurement position when measuring the height of glue dispensing.

[0044] During the measurement process of this application, there is no need to contact the board device. By being able to automatically measure the dispensing height of 8 locations and automatically read the height value, it can stably ensure non-contact measurement of the dispensing height of the device on the board and avoid the risk of damage to the device. At the same time, it is convenient and fast, reduces working hours, improves work efficiency, and is easy to promote and use.
