Tin wave height measuring system and method thereof

Abstract

The invention discloses a tin wave height measuring system and method thereof. The method comprises the steps: arranging a pedestal on a bearing chain claw disposed on a transmission mechanism of wave soldering equipment, enabling a part of the bottom surface of the pedestal to be tightly attached to the bottom bearing surface of the bearing chain claw, and enabling a first metal contact unit disposed on the pedestal to be in contact with tin liquid in a tin furnace; when a measurement controller receives a measurement instruction, controlling an electric sliding table, so that a second metal contact unit arranged at a terminal of a fixed rod fixedly connected with the electric sliding table moves from a preset position to the tin furnace until the second metal contact unit is in contact with the peak top of tin wave in the tin furnace, and a conduction signal is received; and obtaining the height value of the tin wave according to the distance from the second metal contact unit moving from the preset position to the peak top of the tin wave; and a display device being configured to display the height value of the tin wave. Therefore, the tin wave height can be quantitatively and accurately measured.

Description

technical field [0001] The invention relates to a height measuring system and its method, in particular to a tin wave height measuring system and its method. Background technique [0002] At present, when it is desired to use wave soldering equipment to solder electronic components to the circuit board, the wave soldering equipment will clamp and transport the carrier plate carrying the circuit board, so that the circuit board exposed to the soldering surface passes through the surface of the solder wave, and the electronic components on the soldering surface are completed. Soldering of the pins. There are two types of tin waves in wave soldering equipment: advection waves and turbulent waves. The height of these two tin waves is a very important parameter, which will affect the quality of circuit board soldering due to the size and duration of the contact soldering surface. Improper tin wave height will cause continuous soldering or missing soldering of electronic componen...

Problems solved by technology

[0003] However, since there is currently no dedicated tin wave height measurement equipment available, operators of wave soldering equipment usually use simple equipment, such as a steel ruler, to measure by visually observing the readings, but such measurement methods are prone to artificial Influenced by factors, for example: different operators have different operation methods, which will lead to different measurement results, different observation angles will give different results, large errors in visual readings, making the measurement results inaccurate, and the error range may be 1 mm to 3 mm , does not meet the accuracy required by general equipment (that is, 0.1 mm), so that when customers audit production equipment and processes, they often cause audit points to be lost. In severe cases, it may even affect the customer's determination to place an order, which has a huge impact

[0004] To sum up, it can be seen that there is a problem that the quantification of tin wave height is not accurate enough in the existing technology, so it is necessary to propose improved technical means to solve this problem
