Description

Technical Field

[0001] The invention relates to the technical field of electrical component detection equipment, in particular to a fast-plugging electrical female connector tightness detection device. Background Art

[0002] Electrical female connectors are components used to connect electrical equipment or electrical systems, and are commonly used in industries such as industry, aerospace, shipping, railways, and automobiles. They provide a fast, safe, and reliable way to connect, making it easier to connect and disconnect electrical equipment. Female plugs are usually fixedly mounted on one side of the equipment or system, and male plugs are inserted into the female plugs for connection. The plugs usually have metal leads or pins that correspond to the sockets in the connector to achieve electrical connection. Electrical female connectors have a variety of forms and specifications that can be selected according to specific application requirements. They may have different sizes, connection methods, electrical characteristics, and environmental adaptability. Some plugs may also have waterproof, dustproof, corrosion-resistant, and other characteristics to meet the needs of different environments. Existing electrical female connectors need to undergo tightness testing before leaving the factory to ensure the stability of the connection, but this process often requires a lot of manual operation, and the detection efficiency is very low. Summary of the invention

[0003] The object of the present invention is to provide a fast plug-in and pull-out electrical female connector tightness detection device to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a fast-plug electrical female connector tightness detection device comprises a chassis, a conveyor, a rocker adapter, a detection mechanism and a blanking assembly, the conveyor is provided with a plurality of loading tools, each of the loading tools positions the female connector to be detected, the chassis is installed above the conveyor through a bracket, a power assembly is provided inside the chassis, a fixed rotation pin is provided above the chassis, the detection mechanism is installed between the rocker adapter and the fixed rotation pin, the power assembly drives the detection mechanism to move, the blanking assembly is provided on one side of the chassis, the blanking assembly comprises a material stripping tool, the material stripping tool strips the female connector Before testing the female connector, the operator puts the female connector to be tested into the loading jig. Since the first card block is provided with a slope on top, the operator presses the female connector into the upper jig, and the female connector pushes the first card block to the edge until the female connector is pressed into the loading jig. The bottom slope of the first card block contacts the female connector. Since the four first card blocks apply the same thrust to the four edges of the female connector, the female connector is positioned in the middle of the loading jig. The control system controls the conveyor to drive the loading jig to move. After the female connector moves to the bottom of the detection mechanism, the conveyor stops, thereby realizing the positioning of the detection position of the female connector. The power component drives the detection mechanism to operate, thereby realizing the detection of the female connector.

[0005] Furthermore, a servo motor, a worm, a worm wheel, an incomplete gear and a driven gear are installed in the chassis, the worm is connected to the motor shaft of the servo motor, the worm wheel is coaxially connected to the incomplete gear, the worm and the worm wheel are meshingly transmitted, and the driven gear cooperates with the incomplete gear. The servo motor drives the worm to rotate, the worm drives the worm wheel to reduce the speed, and the worm wheel drives the incomplete gear to rotate. When the teeth of the incomplete gear contact the teeth of the driven gear, the driven gear rotates. When the blank section of the incomplete gear rotates to one side of the driven gear, the driven gear stops. The incomplete gear drives the driven gear to rotate half a circle for every rotation of the incomplete gear.

[0006] Furthermore, the detection mechanism includes a crank, a connecting rod and a main rocker, a hollow circular groove is opened on one side of the chassis corresponding to the driven gear, the crank is arranged on the side of the driven gear close to the hollow circular groove, a crank pin is arranged on the end of the crank close to the edge of the driven gear, one end of the main rocker is rotatably connected to the rocker adapter frame, one end of the connecting rod is connected to the crank pin, and the other end of the connecting rod is rotatably connected to one end of the main rocker.

[0007] Furthermore, the detection mechanism includes a slave rocker and a detection rod, the slave rocker is installed on the main rocker, one end of the slave rocker coincides with the end of the transfer section of the main rocker at the rocker adapter, there is an angle between the slave rocker and the main rocker, the length of the slave rocker is greater than the length of the main rocker, the swing angle of the main rocker is 90°, the driven gear rotates half a circle, drives the crank to rotate 180°, the crank drives the connecting rod to move through the crank pin, and drives the main rocker to move from one extreme position to another extreme position through the connecting rod, that is, the main rocker swings 90°, because the slave rocker is fixedly connected to the main rocker Therefore, the driven rocker also swings 90°. With the rotation of the crank, the driven rocker swings back and forth. When the driven rocker swings to the horizontal position, it drives the detection rod to move to the vertical state. When the driven rocker swings to the vertical position, it drives the detection rod to move to the horizontal state, so that the detection rod repeatedly switches between the vertical and horizontal states. Because there is a rest time for the driven gear, the detection rod pauses after reaching the vertical and horizontal states. The detection rod pauses in the vertical state for detecting the female connector, and pauses in the horizontal state for cutting the female connector.

[0008] Furthermore, the detection mechanism also includes a detection rod, a long slide groove is provided on one side of the detection rod, and the long slide groove is slidably connected with the fixed rotating pin, and the end of the driven rocker arm away from the main rocker arm is rotatably connected with the middle part of the detection rod, and the end of the detection rod away from the long slide groove is provided with a cavity, and a pull-out plug is slidably provided inside the cavity, and one end of the pull-out plug extends out of the detection rod, and a spring is provided between one end inside the pull-out plug and the cavity, and the outer sleeve of the spring is provided with a dust cover, and an electromagnet is also provided inside the detection rod, and the electromagnet is connected to a control system through a circuit. Whenever the blank section of the incomplete gear rotates to one side of the driven gear, the slot disk is synchronously rotated to the position of the block, and under the action of the spring top thrust, the block keeps in contact with the slot disk all the time, and the block is pushed into the groove to prevent the slot disk from rotating, thereby preventing the driven gear from rotating uncertainly in the rest state, and when the teeth of the incomplete gear are meshed with the teeth of the driven gear again, the arc contour surface of the groove pushes the block out, so as to achieve the purpose of stopping the driven gear but not locking it.

[0009] Furthermore, a card slot disk is coaxially mounted on one end of the driven gear away from the hollow circular groove, and two grooves are symmetrically arranged at 180° on the card slot disk. A card block is slidably arranged in the chassis, and a spring is connected between the card block and the chassis. A dust cover is arranged on the outer side of the spring, and a push rod is also arranged on one end of the card block connected to the spring. A pressure sensor is arranged at a position corresponding to the push rod in the chassis, and the pressure sensor is connected to the control system circuit. In the initial state, the electromagnet in the detection rod is always powered on, and the electromagnet generates suction to adsorb the unplug plug. The pull-out plug is partially retracted into the cavity. When the card block slides along the surface contour of the card slot disk, the push rod squeezes the pressure sensor. When the card block is embedded in the groove, the push rod is away from the pressure sensor. The pressure sensor sends a signal to the control system. The control system then controls the electromagnet to cut off power once. The electromagnet loses its adsorption force on the pull-out plug, causing the pull-out plug to completely extend out of the cavity under the action of the spring push force. The control system immediately re-energizes the electromagnet after the power is cut off, causing a part of the pull-out plug to retract into the cavity again. That is, each time the pressure sensor sends a signal, the pull-out plug pops out once.

[0010] Furthermore, each of the feeding tools is annular, and each of the feeding tools has four sliding cavities evenly distributed in an annular shape on its inner ring, and a first clamping block is slidably arranged in each of the sliding cavities, and a spring is arranged between each of the first clamping block and the feeding tool, and the upper and lower surfaces of the exposed end of each first clamping block are provided with slopes. When the detection rod is in a vertical state, the pull-out plug will be embedded in the female connector in the feeding tool after it pops out. Because the bottom surface of the first clamping block is also arranged in a slope shape, the female connector is used to tighten the pull-out plug to bring it out. If the female connector cannot be brought out when the pull-out plug is retracted, it means that the tightening force of the female connector on the pull-out plug cannot overcome the squeezing force applied by the first clamping block, which further means that the tightening performance of the female connector does not meet the use requirements. The female connector that cannot meet the use requirements flows out backward along the conveyor, and the operator re-repairs the female connector that has not been brought out.

[0011] Furthermore, the blanking assembly also includes a slide, and the material return tool is installed on one side of the slide, each of the material return tools is annular, and each material return tool has four sliding cavities evenly distributed in an annular shape on its inner ring, and a second clamping block is slidably arranged in each of the sliding cavities, and a spring is arranged between each second clamping block and the material return tool, and only one side of the exposed end of each second clamping block is provided with a slope. When the detection rod is in a horizontal state, the pull-out plug will be embedded in the material return tool after it pops out, and if a female connector is brought out by the pull-out plug, the female connector will pass into the material return tool along the slope surface of the second clamping block, but when the pull-out plug bounces back, the straight surface of the other side of the second clamping block will block the female connector, forcibly separating the female connector from the pull-out plug, and the female connector falls onto the slide and slides out. The reciprocating motion of the detection mechanism is used to detect the tightness of the female connector, and at the same time, the screening of the female connector is completed, thereby improving the working efficiency of the equipment.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] The four first clamping blocks apply the same thrust to the four edges of the female connector, and the female connector is positioned in the middle of the loading tool. The control system controls the conveyor to drive the loading tool to move. After the female connector moves to the bottom of the detection mechanism, the conveyor stops to realize the positioning of the detection position of the female connector. The control system controls the ejection and retraction of the pull-out plug, and the female connector uses the tightening force of the pull-out plug to bring it out. If the female connector cannot be brought out when the pull-out plug is retracted, it means that the tightening force of the female connector on the pull-out plug cannot overcome the squeezing force applied by the first clamping block, further indicating that the tightening performance of the female connector does not meet the use requirements. The reciprocating motion of the detection mechanism is used to detect the tightness of the female connector, and at the same time, the screening of the female connector is completed to improve the working efficiency of the equipment.

Before testing the female connector, the operator puts the female connector to be tested into the loading tool 3. Since the first clamping block 6 is provided with a slope on the top, the operator presses the female connector into the upper material tool 3, and the female connector pushes the first clamping block 6 to the edge until the female connector is pressed into the loading tool 3, and the bottom slope of the first clamping block 6 contacts the female connector. Since the four first clamping blocks 6 apply the same thrust to the four edges of the female connector, the female connector is positioned to the middle of the loading tool 3, and the control system controls the conveyor 2 to drive the loading tool 3 to move. After the female connector moves to the bottom of the detection mechanism, the conveyor 2 stops, so as to realize the positioning of the detection position of the female connector, and the power component drives the detection mechanism to operate, so as to realize the detection of the female connector.

[0027] A servo motor 8, a worm 9, a worm wheel 10, an incomplete gear 11 and a driven gear 12 are installed in the chassis 1. The worm 9 is connected to the motor shaft of the servo motor 8, the worm wheel 10 is coaxially connected to the incomplete gear 11, the worm 9 is meshed with the worm wheel 10 for transmission, the driven gear 12 cooperates with the incomplete gear 11, the detection mechanism includes a crank 18, a connecting rod 20 and a main rocker 21, a hollow circular groove is opened on one side of the chassis 1 corresponding to the driven gear 12, the crank 18 is arranged on the side of the driven gear 12 close to the hollow circular groove, and the end of the crank 18 close to the edge of the driven gear 12 is provided with a A crank pin 19 is provided, one end of the main rocker 21 is rotatably connected to the rocker adapter frame 27, one end of the connecting rod 20 is transferred to the crank pin 19, and the other end of the connecting rod 20 is rotatably connected to one end of the main rocker 21. The detection mechanism includes a slave rocker 22 and a detection rod 23. The slave rocker 22 is installed on the main rocker 21, one end of the slave rocker 22 coincides with the transfer section end of the main rocker 21 on the rocker adapter frame 27, there is an angle between the slave rocker 22 and the main rocker 21, the length of the slave rocker 22 is greater than the length of the main rocker 21, and the swing angle of the main rocker 21 is 90°.

[0028] The servo motor 8 drives the worm 9 to rotate, and the worm 9 drives the worm wheel 10 to decelerate, and the worm wheel 10 drives the incomplete gear 11 to rotate. When the teeth of the incomplete gear 11 contact the teeth of the driven gear 12, the driven gear 12 rotates. When the blank section of the incomplete gear 11 rotates to one side of the driven gear 12, the driven gear 12 stops. The incomplete gear 11 drives the driven gear 12 to rotate half a circle for each rotation. The driven gear 12 drives the crank 18 to rotate 180° for each half rotation. The crank 18 drives the connecting rod 20 to move through the crank pin 19, and drives the main rocker 21 to move from one extreme position to another extreme position through the connecting rod 20, that is, the main rocker 21 swings 90°. Since the driven rocker 2 2 is fixedly connected to the main rocker 21, so the slave rocker 22 also swings 90°. With the rotation of the crank 18, the slave rocker 22 swings back and forth. When the slave rocker 22 swings to the horizontal position, it drives the detection rod 23 to move to the vertical state. When the slave rocker 22 swings to the vertical position, it drives the detection rod 23 to move to the horizontal state, so that the detection rod 23 repeatedly switches between the vertical and horizontal states. Because the driven gear 12 has a rest time, the detection rod 23 pauses after reaching the vertical and horizontal states. The detection rod 23 detects the female connector during the pause time in the vertical state, and cuts the female connector during the pause time in the horizontal state.

[0029] The detection mechanism also includes a detection rod 23, a long slide groove is provided on one side of the detection rod 23, the long slide groove is slidably connected to the fixed rotating pin 24, the end of the slave rocker 22 away from the main rocker 21 is rotatably connected to the middle part of the detection rod 23, the end of the detection rod 23 away from the long slide groove is provided with a cavity, a plug 26 is slidably provided inside the cavity, one end of the plug 26 extends out of the detection rod 23, a spring is provided between one end inside the plug 26 and the cavity, the outer sleeve of the spring is provided with a dust cover 15, and an electromagnet 25 is also provided inside the detection rod 23, and the electromagnet 25 is electrically The road is connected with a control system. Whenever the blank section of the incomplete gear 11 rotates to one side of the driven gear 12, the slot disk 13 is synchronously rotated to the position of the block 14. Under the action of the spring top thrust, the block 14 always keeps in contact with the slot disk 13. The block 14 pushes into the groove to prevent the slot disk 13 from rotating, thereby preventing the driven gear 12 from rotating uncertainly in a rest state. When the teeth of the incomplete gear 11 mesh with the teeth of the driven gear 12 again, the arc contour surface of the groove pushes the block 14 out, so that the driven gear 12 is stopped but not locked.

[0030] A slot disk 13 is coaxially mounted on one end of the driven gear 12 away from the hollow circular groove, and two grooves are symmetrically provided on the slot disk 13 at 180 degrees. A card block 14 is slidably arranged in the chassis 1, and a spring is connected between the card block 14 and the chassis 1. A dust cover 15 is provided on the outer sleeve of the spring. A push rod 16 is also provided at one end of the card block 14 connected to the spring. A pressure sensor 17 is provided at a position corresponding to the push rod 16 in the chassis 1. The pressure sensor 17 is connected to the control system circuit. In the initial state, the electromagnet 25 in the detection rod 23 is always powered on, and the electromagnet 25 generates suction to absorb the pull-out plug 26, so that a part of the pull-out plug 26 is pulled out. When the card block 14 slides along the surface contour of the card slot disk 13, the push rod 16 squeezes the pressure sensor 17. When the card block 14 is embedded in the groove, the push rod 16 is away from the pressure sensor 17. The pressure sensor 17 sends a signal to the control system, and the control system immediately controls the electromagnet 25 to cut off the power once. The electromagnet 25 loses its adsorption force on the pull-out plug 26, so that the pull-out plug 26 is completely extended out of the cavity under the action of the spring top thrust. The control system immediately re-energizes the electromagnet 25 after the power is cut off, so that a part of the pull-out plug 26 is retracted into the cavity again, that is, each time the pressure sensor 17 sends a signal, the pull-out plug 26 pops out once.

[0031] When the detection rod 23 is in a vertical state, the pull-out plug 26 pops out and is embedded in the female connector in the loading tool 3. Because the bottom surface of the first clamping block 6 is also arranged in a slope shape, the female connector is used to tighten the pull-out plug 26 to bring it out. If the female connector cannot be brought out when the pull-out plug 26 is retracted, it means that the tightening force of the female connector on the pull-out plug 26 cannot overcome the squeezing force applied by the first clamping block 6, which further means that the tightening performance of the female connector does not meet the use requirements. The female connector that cannot meet the use requirements flows out backward along the conveyor 2, and the operator rechecks the female connector that has not been brought out. The female connector is repaired, and when the detection rod 23 is in a horizontal state, the plug 26 pops out and embeds into the material return tool 4. If the plug 26 brings out a female connector, the female connector will pass into the material return tool 4 along the slope surface of the second clamping block 7. However, when the plug 26 bounces back, the straight surface of the other side of the second clamping block 7 will block the female connector, forcibly separating the female connector from the plug 26, and the female connector falls onto the slide 5 and slides out. Through the reciprocating motion of the detection mechanism, the tightness of the female connector is detected, and the screening of the female connector is completed at the same time, thereby improving the working efficiency of the equipment.

[0032] The working principle of the present invention is as follows: before testing the female connector, the operator places the female connector to be tested into the loading jig 3. Since a slope is provided on the top of the first clamping block 6, the operator presses the female connector into the upper jig 3, and the female connector pushes the first clamping block 6 to the edge until the female connector is pressed into the loading jig 3, and the bottom slope of the first clamping block 6 contacts the female connector. Since the four first clamping blocks 6 apply the same thrust to the four edges of the female connector, the female connector is positioned in the middle of the loading jig 3, and the control system controls the conveyor 2 to drive the loading jig 3 to move. After the female connector moves to the bottom of the detection mechanism, the conveyor 2 stops, thereby realizing the positioning of the detection position of the female connector, and the power component drives the detection mechanism to operate, thereby realizing the detection of the female connector.

[0033] The servo motor 8 drives the worm 9 to rotate, and the worm 9 drives the worm wheel 10 to decelerate, and the worm wheel 10 drives the incomplete gear 11 to rotate. When the teeth of the incomplete gear 11 contact the teeth of the driven gear 12, the driven gear 12 rotates. When the blank section of the incomplete gear 11 rotates to one side of the driven gear 12, the driven gear 12 stops. The incomplete gear 11 drives the driven gear 12 to rotate half a circle for each rotation. The driven gear 12 drives the crank 18 to rotate 180° for each half rotation. The crank 18 drives the connecting rod 20 to move through the crank pin 19, and drives the main rocker 21 to move from one extreme position to another extreme position through the connecting rod 20, that is, the main rocker 21 swings 90°. Since the driven rocker 2 2 is fixedly connected to the main rocker 21, so the slave rocker 22 also swings 90°. With the rotation of the crank 18, the slave rocker 22 swings back and forth. When the slave rocker 22 swings to the horizontal position, it drives the detection rod 23 to move to the vertical state. When the slave rocker 22 swings to the vertical position, it drives the detection rod 23 to move to the horizontal state, so that the detection rod 23 repeatedly switches between the vertical and horizontal states. Because the driven gear 12 has a rest time, the detection rod 23 pauses after reaching the vertical and horizontal states. The detection rod 23 detects the female connector during the pause time in the vertical state, and cuts the female connector during the pause time in the horizontal state.

[0034] Whenever the blank section of the incomplete gear 11 rotates to one side of the driven gear 12, the slot disk 13 is synchronously rotated to the position of the block 14. Under the action of the spring push force, the block 14 always keeps in contact with the slot disk 13, and the block 14 is pushed into the groove to prevent the slot disk 13 from rotating, thereby preventing the driven gear 12 from rotating in an uncertain manner in a rest state. When the teeth of the incomplete gear 11 mesh with the teeth of the driven gear 12 again, the arc contour surface of the groove pushes the block 14 out, so that the driven gear 12 is stopped but not locked.

[0035] In the initial state, the electromagnet 25 in the detection rod 23 always remains energized, and the electromagnet 25 generates suction to adsorb the plug 26, so that a part of the plug 26 is retracted into the cavity. When the block 14 slides along the surface contour of the card slot disk 13, the push rod 16 squeezes the pressure sensor 17. When the block 14 is embedded in the groove, the push rod 16 is away from the pressure sensor 17, and the pressure sensor 17 sends a signal to the control system. The control system then controls the electromagnet 25 to cut off power once, and the electromagnet 25 loses its adsorption force on the plug 26, so that the plug 26 is completely extended out of the cavity under the action of the spring push force. The control system immediately re-energizes after the electromagnet 25 is powered off, so that a part of the plug 26 is retracted into the cavity again, that is, each time the pressure sensor 17 sends a signal, the plug 26 pops out once.

[0036] When the detection rod 23 is in a vertical state, the pull-out plug 26 pops out and is embedded in the female connector in the loading tool 3. Because the bottom surface of the first clamping block 6 is also arranged in a slope shape, the female connector is used to tighten the pull-out plug 26 to bring it out. If the female connector cannot be brought out when the pull-out plug 26 is retracted, it means that the tightening force of the female connector on the pull-out plug 26 cannot overcome the squeezing force applied by the first clamping block 6, which further means that the tightening performance of the female connector does not meet the use requirements. The female connector that cannot meet the use requirements flows out backward along the conveyor 2, and the operator rechecks the female connector that has not been brought out. The female connector is repaired, and when the detection rod 23 is in a horizontal state, the plug 26 pops out and embeds into the material return tool 4. If the plug 26 brings out a female connector, the female connector will pass into the material return tool 4 along the slope surface of the second clamping block 7. However, when the plug 26 bounces back, the straight surface of the other side of the second clamping block 7 will block the female connector, forcibly separating the female connector from the plug 26, and the female connector falls onto the slide 5 and slides out. Through the reciprocating motion of the detection mechanism, the tightness of the female connector is detected, and the screening of the female connector is completed at the same time, thereby improving the working efficiency of the equipment.
