Description

Technical Field

[0001] The utility model relates to the technical field of plate thickness measuring equipment, in particular to a large table plate thickness measuring instrument. Background Art

[0002] Measure the thickness of super large PCB original board, resin board, copper board, etc. (the measurement size can reach 2.4*1.5 meters) (thickness less than 4mm). There are several problems at present:

[0003] 1. Due to the large thin plate, when measuring one point and needing to measure another point, the measured plate is moved, resulting in scratches;

[0004] 2. Currently, the measurement is mainly performed by fixing the lower laser measurement base point on a movable support, and the upper laser measurement base point is also fixed on a movable support. In this way, when measuring large thin plates, it is necessary to move the upper and lower base points at the same time and emit lasers for measurement. Since the upper and lower base points are not fixed on a rigid connection device, it is easy to cause the accumulation of upper and lower movement errors, resulting in low measurement accuracy.

[0005] For this reason, a large table panel thickness measuring instrument is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve the problems raised in the above background technology, and provide a large table panel thickness measuring instrument.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] A large table panel thickness measuring instrument comprises a frame assembly and a pedal control switch, wherein a measuring platform is fixedly mounted on the top surface of the frame assembly, an air pump is fixedly mounted on the rear side wall of the frame assembly, a cover plate is provided on the top surface of the frame assembly, and an opening is provided on the surface of the cover plate, a thickness measuring assembly for measuring the thickness of a plate is fixedly mounted inside the frame assembly, an air jet assembly is provided on the surface of the frame assembly, and the air jet assembly is connected to the air pump through an air pipe, and a controller is provided on the top surface of the cover plate.

[0009] Furthermore, the frame assembly includes a frame body, side panels are arranged on the left, right and rear sides of the frame body, universal wheels and support legs are fixedly installed on the bottom surface of the frame body, and an air pump is fixedly installed on the rear side wall of the rear side panel.

[0010] Furthermore, the thickness measurement assembly includes a base frame, the base frame is fixedly installed inside the frame body, the top of the base frame is movably connected to the upper frame through a driving device, the top surface of the base frame is fixedly installed with a lower test contact base point, and the bottom end of the upper frame is fixedly installed with a lower test contact base point.

[0011] Furthermore, the jet assembly includes a jet hole, the top surface of the measuring platform is provided with a jet hole, a nozzle is installed on the bottom surface of the measuring platform and opposite to the jet hole, a connection port is provided on the surface of the nozzle, and the connection port is fixedly connected to an air pipe, and the air pipe is connected to the output end of the air pump.

[0012] Furthermore, the controller includes a bracket, the bracket is fixedly mounted on the top surface of the cover plate, a mounting plate is fixedly mounted on the other end of the bracket, and the bracket is connected to a control host via the mounting plate.

[0013] Furthermore, a through hole is opened on the surface of the measuring platform, and the lower test contact base point is located inside the through hole, and during measurement, the upper test contact base point and the lower test contact base point are in contact with the surface of the plate.

[0014] The beneficial effects of the utility model are as follows:

[0015] The upward jet components are evenly arranged on the super-large measuring platform. When the plate to be tested is placed at the beginning and when one point needs to be moved to another point for measurement, the air pump is used to make the jet component spray compressed air of a certain pressure upward, so that there is a layer of gas between the plate to be tested and the measuring platform for physical spacing, so that the plate to be tested will not be scratched when it is moved. The air pressure is controlled by a foot-operated control switch. Before moving the plate, step on the foot-operated control switch to turn on the power of the air pump, then ventilate, and then move. After moving to the test point, lift the foot, then turn off the air pump, and the plate to be tested will remain still on the measuring platform.

[0016] The upper test contact base point and the lower test contact base point are set on the upper frame and the bottom frame respectively, and a large "C"-shaped rigid bracket is formed by the bottom frame and the upper frame. Before the board to be tested is placed on it, the "C"-shaped rigid bracket will be slightly tilted to ensure that the lower test contact base point is not damaged by the board. After placing it on, the "C"-shaped bracket is slightly lifted to make the lower test contact base point touch the lower plane of the board, and then the upper test contact base point is moved down by the driving device to realize the thickness test. Since the "C"-shaped bracket needs to be prevented from lateral movement during the slight downward or upward movement, it is fixed with special bearings to ensure that the upper test contact base point and the lower test contact base point are always vertical to ensure the accuracy of the test.
