A material error-proofing and fool-proofing device for an insertion machine and a method of using the same

Abstract

The present invention discloses a material error-proofing and fool-proofing device for an insertion machine and a method of using the device, including a conveying platform, a top cover, a conveying mechanism, a detection mechanism and a rejection mechanism, wherein the top cover is arranged on the top of the conveying platform, the conveying mechanism is arranged between the conveying platform and the top cover, and the conveying mechanism is composed of a synchronous belt, a mounting plate, a Z-shaped support plate and a positioning plate. The present invention positions the material through a positioning pile. If the material placement deviates, the positioning pile cannot firmly position the material, which is convenient for subsequent rejection. The material is photographed and identified by a CCD camera to identify whether the material is neatly placed. A high-pressure air pump is connected to an air guide pipe. When the material placement deviates, the CCD camera controls the solenoid valve to perform a switch operation, and the air nozzle sprays high-pressure gas to blow the material off, thereby fundamentally eliminating the occurrence of errors, which is beneficial to improving the insertion yield rate and avoiding damage to circuit boards and electronic components.

Description

Technical Field

[0001] The present invention relates to the technical field of plug-in machines, and in particular to a material error-proofing and fool-proofing device for an plug-in machine and a method of using the device. Background Art

[0002] Insertion machines are mechanical devices that automatically and standardly insert some regular electronic components into the conductive through holes of printed circuit boards. Before the insertion machine inserts electronic components into the circuit board, the electronic components need to be neatly arranged according to the regulations so that the insertion structure can pick them up and insert them. Deviations in the placement of electronic components will lead to insertion failures and even damage to the circuit board and electronic components.

[0003] During the operation process, operators may make operating errors due to omissions or forgetfulness, and the quality defects caused by this account for a large proportion. If error proofing can be used to prevent such errors from happening, the quality level and operating efficiency will be greatly improved.

[0004] Error proofing is also known as fool proofing, which aims to prevent errors before they occur. It is a method that uses automatic actions, alarms, labels, and classifications during the operation process to make operators pay less attention and less likely to make mistakes. This method allows operators to directly and obviously find defects during operation or prevent defects from occurring after operating errors. Its characteristics are low cost, real-time error detection, real-time feedback, and full product inspection without increasing the burden on operators.

[0005] The direct result of error proofing is the improvement of product quality. Compared with quality assurance through inspection, error proofing is a preventive measure taken from a prevention perspective. Inspection cannot prevent defects from occurring. Defects found through inspection can only be corrected, which is a waste. Error proofing eliminates this waste.

[0006] The existing plug-in machine is not equipped with a material error prevention and foolproofing device, and it is impossible to remove the materials with deviations in placement before insertion, which can easily lead to insertion failure and even damage to the circuit board and electronic components. For example, the patent discloses an anti-wrong insertion structure of the plug-in machine with application number CN202123283807.5. The patent senses pressure through a pressure sensor. The pressure sensor can effectively detect the preset pressure value when the downward pressure is accurate. If the electronic component is installed incorrectly, the pressure sensor senses the value that exceeds the preset value. When the preset value is exceeded, the pressure sensor sends a signal to let the controller control the electric push rod to stop pressing down, and at the same time control the alarm to sound an alarm to remind nearby staff to come and check. The warning component of the plug-in machine can quickly send a feedback signal when the insertion is wrong to prevent continued insertion from causing damage to the circuit board or electronic components. When the patent prevents the insertion operation, the electronic components have already come into contact with the circuit board, and the damage to the circuit board and electronic components has already occurred. The patent only plays a role in reducing damage after the error occurs, but cannot avoid the occurrence of errors.

[0007] Therefore, it is necessary to invent a material error-proofing and fool-proofing device for an insertion machine and a method of using the same to solve the above problems. Summary of the invention

[0008] The purpose of the present invention is to provide a material error-proofing and fool-proofing device for an insertion machine and a method of using the same, so as to solve the problem that the existing insertion machine is not equipped with a material error-proofing and fool-proofing device, and the material with deviation in placement cannot be removed before insertion, which easily leads to insertion failure and even damages to circuit boards and electronic components.

The rejection mechanism consists of a fixed plate, an air guide tube and an air nozzle. One end of the fixed plate is fixedly connected to the top of the top cover by screws, and the air guide tube is arranged through the other end of the fixed plate. The air nozzle is installed at the bottom of the air guide tube.

[0012] Preferably, a bolt is fixedly connected to the bottom of the positioning plate, and the bottom end of the bolt passes through the Z-shaped support plate and is threadedly connected to a nut.

[0024] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0025] 1. The positioning piles on the positioning plate can be used to limit and fix the material. If the material is placed in a deviation, the positioning piles cannot firmly position the material, making it easier for the subsequent rejection mechanism to reject the material.
