Description

Technical Field

[0001] The present application relates to the technical field of circuit boards, specifically to a measuring fixture for the forming size of circuit boards. Background Art

[0002] A circuit board is a fixed design board that connects electronic components, connectors, conducting wires, etc. It is made of conductive materials, usually an insulating base material covered with copper foil. Circuit boards can be classified in various ways. For example, they can be divided into single-sided boards, double-sided boards, and multi-layer circuit boards according to the number of layers.

[0003] After the circuit board is formed, it needs to be measured for its size to ensure that the product meets the design specifications and quality standards.

[0004] Currently, when measuring a formed circuit board, it is placed in a groove on the fixture for fixation. Subsequently, the length and width dimensions of the circuit board are measured by cooperating a scale and a reading ruler, and the measured data is recorded and compared with the design requirements to analyze whether the circuit board is qualified.

[0005] However, there will be errors in the thickness of the formed circuit board, but the error range is usually small. At the same time, since the length of the reading ruler is fixed, when facing a circuit board with a thickness error, such as a thinner circuit board, the circuit board is slightly lower than the depth of the groove. At this time, the reading ruler may not be able to directly contact the upper surface of the circuit board, resulting in inaccurate readings or difficult to read. When a thicker circuit board is higher than the depth of the groove, due to the blockage of the reading ruler, it cannot be placed in the groove for measurement, and only the fixture can be replaced for measurement, reducing the work efficiency.

[0006] Therefore, it is necessary to provide a measuring fixture for the forming size of circuit boards to solve the above problems.

[0007] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0023] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art of this technology to better understand the solution of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] As Figure 1 and Figure 3 shown, the present application provides a fixture for measuring the forming size of a circuit board, including a base 1. At the same time, an adsorption assembly 3 is provided on the base 1, and the adsorption assembly 3 is used for adsorbing the circuit board. At the same time, a measuring assembly 2 is provided on the base 1, and the measuring assembly 2 is used for measuring the size of the circuit board. And a limiting assembly 4 is provided on the measuring assembly 2, and the limiting assembly 4 is used for restricting the measuring assembly 2. Specifically:

[0026] As Figure 1 shown, the adsorption assembly 3 includes a placing groove 33 opened on the base 1 to facilitate placing the circuit board. At the same time, a plurality of groups of adsorption holes 32 are opened on the base 1, and the adsorption holes 32 are located in the placing groove 33. At the same time, two groups of ventilation ports 31 are provided on the base 1, and the two groups of ventilation ports 31 are respectively communicated with the plurality of groups of adsorption holes 32. It should be noted that the ventilation ports 31 are connected to an external adsorption device to adsorb and fix the circuit board through the adsorption holes 32;

[0027] During measurement, place the circuit board into the placing groove 33, start the adsorption device, and adsorb and fix the circuit board in the placing groove 33 through the ventilation ports 31 and the adsorption holes 32;

[0028] As Figures 1 - 3As shown in the figure, the measuring component 2 includes two sets of scales 21 arranged on the base 1 to facilitate the measurement of the length and width dimensions of the circuit board. At the same time, two sets of sliding grooves 27 are formed on the base 1. A cylinder 26 is slidably arranged inside the sliding groove 27. A connecting column 22 is fixedly installed on the cylinder 26. A first reading scale 23 is fixedly installed at one end of the connecting column 22 away from the cylinder 26. The first reading scale 23 is located above the scale 21.

[0029] At the same time, a rotating part 24 is fixedly installed on the first reading scale 23. A second reading scale 25 is fixedly installed at one end of the rotating part 24 away from the first reading scale 23. It should be noted that the rotating part 24 is an existing rotary damper. The specific structure and principle will not be elaborated in detail here. And the rotation center of the rotating part 24 is away from the first reading scale 23 and does not exceed the placement groove 33 to facilitate the rotation of the second reading scale 25.

[0030] When measuring a conventional circuit board, the second reading scale 25 and the first reading scale 23 are in a horizontal state and are attached to the side wall of the circuit board. At this time, move the connecting column 22 to drive the first reading scale 23 to move, thereby synchronously driving the rotating part 24 and the second reading scale 25 to move on the scale 21 to facilitate the measurement of the size of the circuit board.

[0031] Since there will be errors in the thickness of the circuit board after forming, but the error range is usually small. Therefore, when measuring a slightly thinner circuit board, the circuit board is slightly lower than the depth of the placement groove 33. Rotate the second reading scale 25 downward to make it inclined until it is attached to the side wall of the circuit board. And due to the function of the rotating part 24, it can be fixed at the rotated position, and then measure the size of the circuit board.

[0032] When facing a slightly thicker circuit board, the circuit board is slightly higher than the depth of the placement groove 33. Rotate the second reading scale 25 upward until it is perpendicular to the first reading scale 23. And since the rotation center of the rotating part 24 does not exceed the placement groove 33, it is convenient to retract it so as not to block the placement of the slightly thicker circuit board. Therefore, the circuit board can be placed in the placement groove 33. Then rotate the second reading scale 25 to be attached to the side wall of the circuit board and then measure.

[0033] As Figures 2 - 3 shown, the limiting component 4 includes a nut 41 threadedly arranged on the connecting column 22. It should be noted that a threaded part is provided on the connecting column 22 to cooperate with the nut 41.

[0034] In the initial state, there is a certain gap between the nut 41 and the base 1. When it is necessary to lock the measuring component 2, rotate the nut 41 downward until the nut 41 abuts against the base 1 to fix the connecting column 22, thereby synchronously fixing the measuring component 2 to facilitate reading data. And when measuring the next set of circuit boards, they can be directly placed in the placement groove 33, and it is only necessary to check whether they are in contact with the second reading scale 25;

[0035] In summary, when measuring a circuit board, place the circuit board in the placement groove 33, fix it through the adsorption component 3, then the measuring component 2 measures it, and the measuring component 2 can be fixed through the limiting component 4. When facing circuit boards with different thicknesses, rotate the second reading scale 25 until it is in contact with the side wall of the circuit board, and continue the measurement to prevent only a single circuit board from being measured.

[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
