Description

Technical Field

[0002] The skewed pins of plug-in electronic components may cause the product to fail to be inserted into the board when it is mounted on the whole machine, affecting the production efficiency of the whole machine mounting. Therefore, it is necessary to use a detection machine to detect the pins of the plug-in electronic components to ensure that their pins can be inserted into the PCB board.

[0003] For example, the utility model: "Direct-insertion electronic component pin detection machine", with the announcement number "CN203364760U", uses an optical path system to take images to analyze and measure the position of each pin, and makes comparative judgments based on preset quality indicators. It has a high detection accuracy and completely avoids template errors and human misjudgment. However, during the implementation of this patent, the camera shooting angle is fixed, and it is not easy to capture multiple groups of pins of direct-insertion electronic components at the same time, and it is not convenient to directly find crooked pins. Therefore, the research and development of new direct-insertion electronic component pin detection machines has received more and more attention from researchers. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides an embodiment: a plug-in type electronic component pin detection machine, comprising a base 1, a mounting sleeve 3, a lifting plate 9 and a mounting plate 26, a mounting plate 26 is installed at one end of the top of the base 1, and a top plate 11 is installed on the top of the mounting plate 26, a first sliding component 8 is installed on the inner side of the mounting plate 26, and the lifting plate 9 is slidably installed at one end of the first sliding component 8 away from the mounting plate 26, a first clamping plate 15 is installed at one end of the bottom of the lifting plate 9 close to the first sliding component 8, and a fixing plate 20 is installed at one end of the bottom of the lifting plate 9 away from the first sliding component 8 The top of the base 1 is evenly installed with a mounting sleeve 3, and the bottom of the mounting sleeve 3 close to the mounting plate 26 is installed with an LED lamp 2, both ends of the mounting sleeve 3 are provided with guide grooves 21, and the inside of the mounting sleeve 3 is installed with a connecting block 5, the top of the connecting block 5 is installed with a pin contact pin 6, and the bottom of the connecting block 5 is installed with a connecting rod 16, the bottom of the connecting rod 16 is installed with a second conductive sheet 24, and the bottom of the mounting sleeve 3 is installed with a first conductive sheet 23, and the output end of the first conductive sheet 23 is electrically connected to the input end of the LED lamp 2 through a wire.

[0022] In this implementation:

[0023] Furthermore, a mounting hole 14 is provided inside the top plate 11, and a pushing rod 10 is installed inside the mounting hole 14. A pushing plate 13 is installed on the top of the pushing rod 10. The pushing plate 13 pushes the pushing rod 10 to move, so that the pushing rod 10 can push the lifting plate 9 to move.

[0024] Furthermore, a second return spring 12 is installed at the bottom of the pushing plate 13, and the end of the second return spring 12 away from the top plate 11 is connected to the pushing plate 13. When the pushing plate 13 is no longer pushed, the elastic action of the second return spring 12 pushes the pushing plate 13 to move upward and reset, thereby driving the lifting plate 9 to move upward and reset.

[0025] Furthermore, a second sliding assembly 17 is installed at one end of the bottom of the lifting plate 9 away from the first clamping plate 15, and a second clamping plate 18 is slidably installed at the bottom of the second sliding assembly 17, and a fixing spring 19 is installed at one end of the second clamping plate 18 away from the first clamping plate 15, and one end of the fixing spring 19 away from the second clamping plate 18 is connected to the fixing plate 20. When in use, the plug-in type electronic components are placed between the first clamping plate 15 and the second clamping plate 18, and the elastic action of the fixing spring 19 causes it to push the second clamping plate 18 to move, so that the second clamping plate 18 is tightly fitted with the outside of the electronic components, and the electronic components can be clamped by the first clamping plate 15 and the second clamping plate 18 for detection.

[0026] Furthermore, a baffle 7 is installed on the top of the mounting plate 26 near one end of the first sliding assembly 8 . When the first clamping plate 15 contacts the baffle 7 , the lifting plate 9 cannot continue to move downward. At this time, the first conductive sheet 23 contacts the second conductive sheet 24 .

[0027] Furthermore, guide blocks 22 are installed at both ends of the connecting block 5. When in use, the guide blocks 22 move inside the guide grooves 21. The connecting block 5 is limited by the guide blocks 22 so that the connecting block 5 can only move in a straight line in the vertical direction.

[0028] Furthermore, a fixing block 25 is installed at the bottom of both ends of the mounting sleeve 3, and a first return spring 4 is installed at the top of the fixing block 25. The end of the first return spring 4 away from the fixing block 25 is connected to the connecting block 5. When the pin contact pin 6 stops pushing, the elastic action of the first return spring 4 pushes the connecting block 5 to move upward and reset.

[0029] Working principle:

[0030] When in use, the device is connected to a power source, at which time, the second conductive sheet 24 is energized;

[0031] The staff can place the plug-in type electronic components between the first clamping plate 15 and the second clamping plate 18, and make the pins face the pin contact pins 6 below. The elastic action of the fixing spring 19 pushes the second clamping plate 18 to move, so that the second clamping plate 18 is closely attached to the outer side of the electronic components, and the electronic components can be clamped by the first clamping plate 15 and the second clamping plate 18 for testing;

[0032] During the inspection, the staff can push the push plate 13 to move downward, and the push plate 13 drives the lifting plate 9 to move downward through the push rod 10. At this time, the normal pin can directly contact the pin contact pin 6, and the crooked pin cannot contact the pin contact pin 6;

[0033] The staff continues to push the push plate 13, so that the lifting plate 9 continues to move downward. When the first clamping plate 15 contacts the baffle plate 7, the push plate 13 is stopped. At this time, the pin contact pin 6 drives the connecting block 5 to move downward. The connecting block 5 drives the second conductive sheet 24 to move through the connecting rod 16, so that the second conductive sheet 24 contacts the first conductive sheet 23, so that the first conductive sheet 23 can be energized, that is, the LED lamp 2 can be energized through the first conductive sheet 23, and the LED lamp 2 can emit light;

[0034] The crooked pins never contact the pin contact pins 6 during the movement of the lifting plate 9, so that the corresponding pin contact pins 6 cannot move downward, so that the first conductive sheet 23 and the second conductive sheet 24 cannot contact each other, and the corresponding LED lamps 2 below will not be powered on and emit light;

[0035] Therefore, during the detection process, the staff can judge whether the pins are skewed by the light emission of the multiple groups of LED lights 2, so as to quickly find the skewed pins on the direct-insert electronic components.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
