Description

Technical Field

[0001] The invention relates to the technical field of patch lead feeding, in particular to a feeding device for patch lead production. Background Art

[0002] The patch lead is a commonly used electronic component. It is composed of a sheet material with a circuit board. It can connect the printed circuit board with the external circuit. It is used to connect multiple electronic components and is an important part of the electronic component to complete its function. The production of patch leads requires a series of strict processes such as printing, welding, and inspection. In order to improve production efficiency, a conveying mechanism is used to convey the lead patch frame as a carrier so that each process point can be connected in series. The existing conveying mechanism such as a crawler structure is used. When the conveyor belt moves, it will rotate to the bottom of the conveyor roller for a cycle feeding. On the current patch lead production line, the patch frame sheet can be connected in series with each process through the crawler conveyor mechanism, including loading, marking, brushing solder paste, soldering patch, reflow soldering and other processes. During production, the entire process is transported by the conveying mechanism, and a series of processes are completed on the conveying mechanism.

[0003] At present, due to the numerous production processes of patch leads, the overall production line is too large. Due to different user needs or different products, the required patch leads and circuit board sizes and models are also different. Therefore, the following problems may exist in production:

[0004] 1. When transporting circuit boards of different sizes and models, it is necessary to use a driving device such as a cylinder to adjust the distance between the conveying mechanisms. However, the coordination between the equipment is relatively precise, and the fixtures installed on the conveying mechanism are also interrelated, so the progress in debugging the equipment is slow, which easily affects the production process;

[0005] Second, the existing chip lead production line processes directly after the chip frame is loaded, and then inspects it at the end. Although the efficiency is improved, the defective products will also increase. Even if the inspection is carried out after loading, the chip frame is guided by the tight fit between the conveying mechanism, so the chip frame cannot be taken out directly for repair in time, which finally leads to the waste of materials and also increases the overall defective rate of the product.

[0006] In view of this situation, the present invention provides a feeding device for patch lead production, the purpose of which is to be able to inspect the patch frame after it is loaded, and to remove it in time after problems are found, thereby avoiding material waste and reducing the defective rate. In addition, the designed fixture can support patch frames of different specifications, thereby reducing the number of equipment that needs to be debugged on the production line, speeding up the debugging speed while also improving the production progress.

A motor 2 909 is fixedly connected to one side of the gantry 901. One end of the output shaft of the motor 2 909 is connected to the screw rod 902 is fixedly connected, the outer walls of the screw rod 902 and the driven shaft 906 are respectively fixedly connected with a driving gear 912 and a driven gear 911, the driving gear 912 and the driven gear 911 are meshed with each other, the outer wall of the driven shaft 906 is provided with a synchronous belt 914, the rotating shaft 917 is transmission-connected with the driven shaft 906 through the synchronous belt 914, the outer wall of the screw rod 902 is threadedly connected with a moving seat 913, the bottom of the moving seat 913 is fixedly connected with an electric telescopic rod 904, the telescopic end of the electric telescopic rod 904 is fixedly connected with an extraction component 905, the interior of the gantry 901 is fixedly connected with a guide rod 910, the moving seat 913 is slidably connected with the guide rod 910, the number of the driven shaft 906 and the moving seat 913 are both two, and the clamping mechanism 6 includes a base 61, the base 61 is slidably connected to the conveyor belt placement frame of the conveying component 1 4, the conveying component 3 8 and the conveying component 2 5, a limit sensor is provided inside the base 61, the base 61 is internally slidably connected with a sliding shell 64, one side of the sliding shell 64 is movably clamped with a clamping seat 65, one side of the clamping seat 65 is fixedly connected with a fixed clamping plate 66, the extraction component 905 is located above the fixed clamping plate 66, the extraction component 905 includes a base block, an electric cylinder, a slider and an electromagnet, the base block is fixedly connected to the telescopic end of the electric telescopic rod 2 904, the electric cylinder is fixedly connected to the inside of the base block, the base block is internally slidably connected with a slider, the telescopic end of the electric cylinder is fixedly connected to the slider, the bottom of the slider is fixedly connected to the electromagnet, and the electromagnet can be magnetically connected to the fixed clamping plate 66.

[0038] In the above technical scheme, the patch frame is detected when passing through the camera 903, and the existing camera recording comparison technology is used to detect the patch frame. When the technical features of the photographed photo are consistent with the technical features of the qualified photo, the patch frame is passed, and the production and processing of the patch lead of the patch frame is continued. If there is an abnormality, the patch frame will be extracted. The surface of the patch frame will have dust due to storage, processing, and transportation, resulting in abnormal detection. There are also abnormalities in incoming material defects. At this time, the electric telescopic rod 904 can be operated to make the extraction component 905 descend, wherein the electric After the magnet contacts the fixed clamping plate 66, the electromagnet opens to adsorb the fixed clamping plate 66. After the electromagnet adsorbs the fixed clamping plate 66, the electric telescopic rod 904 rises to make the card seat 65 separate from the sliding shell 64. The patch frame is located between the moving clamping plate 67 and the fixed clamping plate 66, so the patch frame will also rise with the rise of the card seat 65. After that, the motor 909 drives the screw rod 902 to rotate, so that the threaded moving seat 913 slides along the guide rod 910. At the same time, the rotation of the screw rod 902 makes the driving gear 912 and the driven gear 913 move. The wheels 911 are meshed with each other, thereby driving the driven shaft 906 to rotate, and then the synchronous belt 914 is used to make the rotating shaft 917 rotate synchronously, so that the turntable 916 and the boss 918 rotate, and the boss 918 is slidably connected with the slide bar 919. Therefore, when the slide bar 919 moves, the slide table 920 and the fixed plate 915 slide back and forth inside the mounting frame 907, so that the cleaning wheel 908 can move back and forth to meet the cleaning of patch frames of different sizes, and the cleaning wheel 908 moves back and forth, and cooperates with the extension and retraction of the electric telescopic rod 904 to improve the cleaning quality. The small holes and concave surfaces inside the patch frame are effectively cleaned. After the cleaning is completed, a manual inspection is performed on one side of the conveying component three 8. If it is a dust problem and there is no incoming material defect, the patch frame will be sent back, and specifically, the card holder 65 will be snap-connected with the sliding shell 64 again, and then production and processing will continue. If there is an incoming material defect, the patch frame and the card holder 65 will stay above the conveying component three 8, and the other half of the clamping mechanism 6 (the part of the base 61) will continue to run. After running to the bottom of the card holder 65, the card holder 65 will be snap-connected with the sliding shell 64.

[0039] In this embodiment, the synchronous belt 914 is connected to the driven shaft 906 and the rotating shaft 917 through a pulley, which is the prior art and will not be described in detail.

[0040] The top of the base 61 is fixedly connected to a motor 62, one end of the output shaft of the motor 62 is fixedly connected to a screw 69, the screw 69 is rotatably connected to the inside of the base 61, the outer wall of the screw 69 is threadedly connected to a slide plate 610, the slide plate 610 is slidably connected to the base 61, the bottom of the slide plate 610 is fixedly connected to two synchronization pins 611, the two synchronization pins 611 are slidably connected to the base 61, the synchronization pins 611 penetrate the bottom of the base 61 and are located inside the conveyor belt, the inside of the base 61 is fixedly connected to an electric telescopic rod 3 616, the telescopic end of the electric telescopic rod 3 616 is fixedly connected to the sliding shell 64, the inside of the base 61 is rotatably connected to a plurality of pulleys 63, the pulleys 63 are slidably connected to the placement rack of the conveyor belt, the inside of the card seat 65 is fixedly connected to an electric telescopic rod 1 613, the telescopic end of the electric telescopic rod 1 613 is fixedly connected to a shell 68, the inside of the shell 68 is rotatably connected to a camshaft 612, the shell 68 A spring 614 is fixedly connected to the inside of the housing 68, a moving splint 67 is fixedly connected to the top of the spring 614, a pin 615 is fixedly connected to the bottom of the moving splint 67, the pin 615 is slidably connected to the housing 68, the camshaft 612 is in contact with the moving splint 67, a motor is arranged inside the housing 68, one end of the motor output shaft is fixedly connected to the camshaft 612, a translation machine 2 3 is arranged on one side of the conveying component 3 8, a conveying component 2 5 is arranged on the translation track of the translation machine 2 3, a blanking machine 10 is installed on one side of the translation machine 2 3, there are two conveying components 3 8, the clamping mechanism 6 can be recycled through the conveying component 1 4 and the conveying component 3 8 and the conveying component 2 5, the conveying component 1 4 and the conveying component 2 5 can be respectively parallel to the two conveying components 3 8, the conveying components 1 4, the conveying components 2 5 and the conveying belts of the conveying components 3 8 are provided with a plurality of positioning holes, and the synchronization pin 611 can be inserted into the inside of the positioning hole.

[0041] In the above technical solution, the clamping mechanism 6 can be adjusted according to the size of the patch frame, mainly by driving the sliding shell 64 to move through the electric telescopic rod 3 616, so that the distance between the two clamping mechanisms 6 is adjusted to meet the width of the patch frame, and the shell 68 is driven to move through the electric telescopic rod 1 613, so as to adjust the distance between the moving clamp 67 and the fixed clamp 66 to meet the thickness of the patch frame. When the patch frame enters the clamping mechanism 6, the moving clamp 67 is moved upward by the rotation of the cam shaft 612, and the patch frame is clamped between the fixed clamp 66 and the moving clamp 67. The patch frame is fixed, wherein a plurality of positioning holes are opened on the conveyor belt, and the clamping mechanism 6 is fixed to the conveyor belt through these positioning holes, and is positioned in cooperation with the limit sensor set up inside the base 61, wherein the motor 1 62 is used to drive the screw 69 to rotate, so that the threaded slide plate 610 drives the synchronous pin 611 to move, so that the synchronous pin 611 is inserted into the positioning hole, thereby achieving the fixation of the conveyor belt and the clamping mechanism 6, and the pulley 63 can slide in the placement frame of the conveyor belt to play a guiding role, so that the clamping mechanism 6 can be docked between the conveyor component 1 4, the conveyor component 2 5, and the conveyor component 3 8.

[0042] A collecting box 11 is fixedly connected to one side of the translation machine 2, and a frame limit assembly 13 is provided inside the conveying assembly 4; the frame limit assembly 13 includes a first electric cylinder, a second electric cylinder, a slide seat and an L-shaped baffle plate, the first electric cylinder is fixedly connected to the inside of the conveying assembly 4, the second electric cylinder is fixedly connected to the inside of the slide seat, the slide seat is slidably connected to the conveying assembly 4, the telescopic end of the first electric cylinder is fixedly connected to the slide seat, and the L-shaped baffle plate is fixedly connected to the telescopic end of the second electric cylinder.

[0043] In the above technical solution, the frame limit component 13 is used to limit the position of the patch frame according to its length, so that the clamping mechanism 6 can support the middle part of both sides of the patch frame, so as to better fix the patch frame. The first electric cylinder is operated to push the slide seat inside the conveying component 4 to slide, and the distance to be limited is determined. Then, the second electric cylinder is operated to extend the L-shaped baffle to block the patch frame from continuing to move, thereby limiting the patch frame. After the clamping mechanism 6 fixes the patch frame, the L-shaped baffle descends to release the restriction on the patch frame and will not interfere with the patch frame.

[0044] In this embodiment, if there is a defect in the incoming material, the patch frame and the holder 65 stay above the conveying component three 8, and the other half of the clamping mechanism 6 (the part of the base 61) continues to run. After running to the bottom of the holder 65, the holder 65 is clamped with the sliding shell 64, and then the conveying component 4 on the translation machine 2 docks the clamping mechanism 6, and then the frame limiting component 13 pushes the patch frame to the collection box 11 for collection, which is convenient for subsequent unified repair. Among them, the limiting principle of the patch frame is the same as that when loading the material, except that this time the L-shaped baffle pushes the patch frame into the collection box 11. In order to improve production efficiency, manual inspection can be cancelled. When the camera 903 detects an abnormality, the patch frame is extracted, regardless of whether it is due to Due to dust, it does not return, and the rotation of the cleaning wheel 908 can also be stopped during this period, and the extension and retraction of the electric telescopic rod 2 904 are coordinated to adjust the height of the patch frame. The patch frame is no longer cleaned, and the patch frame is directly sent to the top of the conveying component 3 8, while the other half of the clamping mechanism 6 continues to run. After running to the bottom of the card seat 65, the card seat 65 is clamped with the sliding shell 64, and then the clamping mechanism 6 is docked by the conveying component 4 on the translation machine 2, and then the patch frame is pushed to the collection box 11 for collection through the frame limit component 13. In addition, according to the actual designed production process, multiple extraction mechanisms 9 can be set up on the patch lead production line to improve production efficiency while detecting the patch frame.

[0045] Several clamp limit assemblies 12 are arranged inside the conveying assembly 1 4, the conveying assembly 3 8 and the conveying assembly 2 5; each clamp limit assemblies 12 includes an electric push rod, a fixed block and a baffle, and the conveying assembly 1 4, the conveying assembly 2 5 and the conveying assembly 3 8 are respectively fixedly connected to the corresponding electric push rods, the fixed block is fixedly connected to the placement frame of the conveyor belt, the telescopic end of the electric push rod is fixedly connected to the baffle, and the baffle is slidably connected to the inside of the fixed block.

[0046] In the above technical scheme, the clamping mechanism 6 is docked from the conveying component 1 4 to the conveying component 3 8: first, the synchronization pin 611 is disengaged from the positioning hole, and then the friction force generated by the contact between the conveyor belt and the base 61 is used to move, that is, the clamping mechanism 6 is still running through the conveyor belt. When the clamping mechanism 6 in the conveying component 1 4 moves close to the conveying component 3 8, it continues to move and enters the conveying component 3 8. This is because the base 61 can slide in the conveying component 1 4, the conveying component 3 8 and the conveying belt placement rack of the conveying component 2 5, and the presence of the pulley 63 provides a guide for the transfer of the base 61, so that it can smoothly enter the placement rack to complete the docking. The clamping mechanism 6 is moved from the conveying component 3 8 to the conveying component 2 5 is the same as the docking principle. It should be noted that after the clamping mechanism 6 is docked, it should continue to be fixed with the conveyor belt to ensure that the clamping mechanism 6 can continue to run at high speed. The clamp limit assembly 12 is required to assist in positioning. The clamp limit assembly 12 can limit the position of the clamping mechanism 6, that is, the conveyor belt continues to run, but the clamping mechanism 6 remains stationary (when the synchronization pin 611 is not inserted into the positioning hole). The baffle is pushed out by the electric push rod to block the base 61, so that the clamping mechanism 6 is immobile. When the positioning hole on the conveyor belt moves to the position of the synchronization pin 611 (cooperating with the limit sensor set inside the base 61 for positioning), the synchronization pin 611 is inserted into the positioning hole.

[0047] How it works:

[0048] When in use, the prior art puts the patch frame into the material storage box, and then pushes the patch frame in the material storage box through the loading machine 1, and pushes the patch frame into the clamping mechanism 6 in the conveying component 4 for fixing, wherein the clamping mechanism 6 is adjusted according to the size of the patch frame, mainly by driving the sliding shell 64 to move through the electric telescopic rod 3 616, so that the distance between the two clamping mechanisms 6 is adjusted to meet the width of the patch frame, and the shell 68 is driven to move through the electric telescopic rod 1 613, so as to adjust the distance between the moving clamp 67 and the fixed clamp 66 to meet the thickness of the patch frame. When the patch frame enters the clamping mechanism 6, the moving clamp 67 is moved upward by the rotation of the cam shaft 612, and the patch frame is clamped between the fixed clamp 66 and the moving clamp 67, so that the patch frame can be fixed;

[0049] Among them, the frame limit component 13 can be used to limit the position of the patch frame according to its length, so that the clamping mechanism 6 can support the middle part of both sides of the patch frame, so that the patch frame can be better fixed. Among them, through the operation of the first electric cylinder, the slide is pushed to slide inside the conveying component 4, and the distance to be limited is determined. Then, the second electric cylinder is operated to extend the L-shaped baffle to block the patch frame from continuing to move, thereby limiting the patch frame. After the clamping mechanism 6 fixes the patch frame, the L-shaped baffle descends to release the restriction on the patch frame and will not interfere with the patch frame.

[0050] Among them, a plurality of positioning holes are opened on the conveyor belt, and the clamping mechanism 6 is fixed on the conveyor belt through these positioning holes, and is positioned in cooperation with the limit sensor set up inside the base 61, wherein the motor 1 62 is used to drive the screw 69 to rotate, so that the threaded slide plate 610 drives the synchronous pin 611 to move, so that the synchronous pin 611 is inserted into the positioning hole, so that the conveyor belt and the clamping mechanism 6 are fixed, and the pulley 63 slides in the placement frame of the conveyor belt to play a guiding role, so that the clamping mechanism 6 can be docked between the conveyor component 1 4, the conveyor component 2 5, and the conveyor component 3 8;

[0051] The clamping mechanism 6 is docked from the conveying component 1 4 to the conveying component 3 8: first, the synchronization pin 611 is disengaged from the positioning hole, and then the friction force generated by the contact between the conveyor belt and the base 61 is used to move, that is, the clamping mechanism 6 is still running through the conveyor belt. When the clamping mechanism 6 in the conveying component 1 4 moves close to the conveying component 3 8, it continues to move and enters the conveying component 3 8. This is because the base 61 can slide in the conveying component 1 4, the conveying component 3 8 and the conveying belt placement rack of the conveying component 2 5, and the presence of the pulley 63 provides a guide for the transfer of the base 61, so that it can smoothly enter the placement rack to complete the docking. The principle of the clamping mechanism 6 docking from the conveying component 3 8 to the conveying component 2 5 is the same. It should be noted that after the clamping mechanism 6 is docked, it must continue to be fixed to the conveyor belt to ensure that the clamping mechanism 6 can continue to run at high speed, and the clamp limit assembly 12 is required to assist in positioning;

[0052] The clamp limit assembly 12 can limit the position of the clamping mechanism 6, that is, the conveyor belt continues to run, but the clamping mechanism 6 remains stationary (when the synchronization pin 611 is not inserted into the positioning hole), wherein the baffle is pushed out by the electric push rod to block the base 61, so that the clamping mechanism 6 is immobile, and when the positioning hole on the conveyor belt moves to the position of the synchronization pin 611, the synchronization pin 611 is inserted into the positioning hole;

[0053] Detection of the patch frame: The patch frame is detected when passing through the camera 903. The patch frame is detected by using the existing camera recording comparison technology. When the technical features of the photographed photo are consistent with the technical features of the qualified photo, the patch frame is passed and the patch lead production and processing is continued. If it is abnormal, the patch frame will be extracted and transported;

[0054] The surface of the patch frame may be dusty during storage, processing and transportation, which may lead to abnormal detection and abnormal material defects. At this time, the extraction component 905 is lowered by the operation of the electric telescopic rod 2 904. After the electromagnet contacts the fixed clamping plate 66, the electromagnet opens to adsorb the fixed clamping plate 66. In addition, it should be pointed out that the electric telescopic rod 3 616 drives the sliding shell 64 to adjust the distance, and the electric cylinder in the base block will also move the slider and the electromagnet, so that the fixed clamping plate 66 can always cooperate with the electromagnet.

[0055] After the electromagnet adsorbs the fixed clamping plate 66, the electric telescopic rod 904 rises, so that the card seat 65 is separated from the sliding shell 64, and the patch frame is located between the moving clamping plate 67 and the fixed clamping plate 66, so the patch frame will also rise with the rise of the card seat 65. Afterwards, the motor 909 drives the screw rod 902 to rotate, so that the threaded moving seat 913 slides along the guide rod 910. At the same time, the rotation of the screw rod 902 makes the driving gear 912 mesh with the driven gear 911, thereby driving the driven shaft 906 to rotate, and then the synchronous belt 914 is used to make the rotating shaft 917 rotate synchronously, thereby making the turntable 916 and the boss 918 rotate, and the boss 918 is slidably connected with the slide bar 919, so when the slide bar 919 moves, the slide table 920 and the fixed plate 915 can slide back and forth inside the mounting frame 907, so that the cleaning wheel 908 can move back and forth to meet the cleaning of patch frames of different sizes, and the cleaning wheel 908 moves back and forth, and the extension and retraction of the electric telescopic rod 2 904 can improve the cleaning quality, and effectively clean the small holes and concave surfaces inside the patch frame. After the cleaning is completed, a manual inspection is performed on one side of the conveying component 3 8. If it is a dust problem, the patch frame is sent back, and specifically, the card holder 65 is clamped with the sliding shell 64 again, and then the production and processing are continued;

[0056] If there is a defect in the incoming material, the patch frame and the holder 65 stay above the conveying component three 8, and the other half of the clamping mechanism 6 (the part of the base 61) continues to run. After running to the bottom of the holder 65, the holder 65 is clamped with the sliding shell 64, and then the conveying component one 4 on the translation machine one 2 docks the clamping mechanism 6, and then the patch frame is pushed to the collection box 11 for collection through the frame limiting component 13, which is convenient for subsequent unified repair. Among them, the limiting principle of the patch frame is the same as that of the material loading, except that this time the L-shaped baffle pushes the patch frame into the collection box 11;

[0057] In order to improve production efficiency, manual inspection can be cancelled. When the camera 903 detects an abnormality, the patch frame will be extracted and will not be returned regardless of whether it is due to dust. During this period, the rotation of the cleaning wheel 908 can be stopped, and the extension and retraction of the electric telescopic rod 2 904 can be coordinated to adjust the height of the patch frame. The patch frame will no longer be cleaned, and the patch frame will be directly sent to the top of the conveying component 3 8, while the other half of the clamping mechanism 6 continues to run. After running to the bottom of the card seat 65, the card seat 65 is then clamped with the sliding shell 64, and then the conveying component 4 on the translation machine 2 docks the clamping mechanism 6, and then the patch frame is pushed to the collection box 11 for collection through the frame limit component 13. In addition, according to the actual designed production process, multiple extraction mechanisms 9 can be set up on the patch lead production line to improve production efficiency while detecting the patch frame;

[0058] The patch frame that has undergone processing techniques such as patch and reflow soldering is finally collected by the unloading machine 10 of the prior art. It is explained again that the clamping mechanism 6 is cyclically used after repeated docking with the conveying component 1 4, the conveying component 3 8 and the conveying component 2 5. It should be specially explained that: when the holder 65 is separated from the sliding shell 64, the base 61 can continue to operate, and the position of the holder 65 is the position for clamping the patch frame. After the base 61 is circulated and located above the holder 65, it can be clamped together again.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
