Description

Technical Field

[0001] The present invention relates to the technical field of pin insertion equipment products, and in particular to an automatic pin insertion device based on incoming material induction. Background Art

[0002] During the PCB production process, a large number of pins (pins), small metal needles, sometimes need to be assembled onto the PCB. The traditional method involves purchasing the pins from the market and manually inserting them one by one into the pinholes of the PCB. These pins are then compressed using a clamp, or the PCB, after being inserted with the pins, is placed on a small stamping machine to compress the pins. This method, on the one hand, results in high raw metal pin prices and labor costs, which increases production costs; on the other hand, manual labor efficiency is low, failing to keep up with the demands of modern society, resulting in low production efficiency. Furthermore, manual determination of the placement and compression of the pins raises concerns about whether the pins are correctly positioned in the pinholes, whether they are inserted to the required depth, and whether they are securely fastened to the PCB. This results in low reliability of the entire process, poor product quality, and consequently, low production precision.

[0003] In recent years, with the rapid development of industry and commerce, the automation industry has grown rapidly. To improve production efficiency, reduce costs, save time, and meet the shortage of human resources, especially in the electronics-related industries, a large number of human resources are needed to solve the production problems of enterprises. However, the lack of human resources and the continuous increase in labor costs have made it increasingly difficult for enterprises to solve production problems. Therefore, in order to survive and develop, enterprises have to adopt automation in the production process to improve the market competitiveness of their products.

[0004] Therefore, automated pin insertion equipment has emerged. This automated pin insertion equipment works by placing commercially available metal pins into the machine, which then automatically inserts the pins one by one into the pinholes of the PCB board. Once inserted, the pins securely bond to the PCB board. However, there are still some drawbacks: Due to the small size of the metal pins, they often overlap during transport, making it difficult for the automated pin insertion equipment to eject the pins, resulting in insertion difficulties. The pins can even become stuck during transport, causing significant trouble for manufacturers. Summary of the Invention

[0017] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific examples, but the following examples are only preferred embodiments of the present invention, not all. Based on the examples in the embodiments, other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention. The experimental methods in the following examples, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following examples, unless otherwise specified, can be obtained from commercial channels.

[0018] Example: Figure 1-11 As shown, an automatic pin insertion device based on incoming material sensing includes a frame 2, four groups of supporting legs arranged in a rectangular array are fixedly installed at the bottom of the frame 2, a material receiving box 3 is placed at the bottom of the frame 2, and a storage bin 5 is opened on the side of the material receiving box 3 on the frame 2. A safety door 4 is hingedly installed on the front side of the frame 2, and an operation panel 1 is provided on the safety door 4. A pin insertion mechanism 6, a needle loading mechanism 7, a pin insertion base 8, a grabbing mechanism 9 and a plastic part feeding channel 10 are sequentially arranged on the rear side of the safety door 4 in the frame 2. The pin insertion mechanism 6 is located at the inner wall of the rear side of the frame 2, the needle loading mechanism 7 is located in front of the pin insertion mechanism 6, the pin insertion base 8 and the plastic part feeding channel 10 are located in front of the needle loading mechanism 7, the pin insertion base 8 and the plastic part feeding channel 10 are arranged horizontally, and the grabbing mechanism 9 is located in the middle of the interval between the pin insertion base 8 and the plastic part feeding channel 10.

[0019] In actual use, when it is necessary to insert pins into plastic parts, the plastic parts are preferably fed into the plastic part feeding channel 10 through the external vibrating feeding tray. At this time, the grabbing mechanism 9 grabs the plastic parts on the plastic part feeding channel 10 and places them on the pin insertion base 8. At the same time, the user places the pins into the needle feeding mechanism 7. At this time, the needle feeding mechanism 7 feeds the individual pins in sequence. When the pins move to the insertion position, the pin insertion mechanism 6 is driven, causing the pins to be inserted into the pin insertion position of the plastic part. After the pin insertion is completed, the pin insertion base 8 rotates to push the finished product to the unloading position. Then the pin insertion operation of the next group of plastic parts continues.

[0020] like Figure 9 and Figure 10As shown, the pin insertion mechanism 6 includes an adjustment frame 42, a second dual-axis motor 40, a first gear 41, a third slide 45, a third threaded rod 46, a second gear 47, a mounting seat 43, a positioning seat 44, a fourth electric push rod 48, a push knife 50 and a fifth electric push rod 49. The adjustment frame 42 is arranged in an inverted U-shaped structure. The second dual-axis motor 40 is fixedly installed on the top inner side of the adjustment frame 42. The first gear 41 is fixedly installed on the output end of the second dual-axis motor 40. The inner walls of both sides of the adjustment frame 42 are provided with third slides 45. The inner top and bottom of the third slide 45 are rotatably installed with a third threaded rod 46. The third The top of the threaded rod 46 is fixedly installed with a second gear 47 that is meshed with the first gear 41. The third slide groove 45 has a built-in third slider. The third slider is sleeved on the third threaded rod 46 and threadedly connected to the third threaded rod 46. The corresponding side wall of the third slider is fixedly installed with a fourth electric push rod 48. The telescopic end of the fourth electric push rod 48 is fixedly installed with a mounting seat 43. The bottom of the mounting seat 43 is fixedly installed with a C-shaped bracket. The C-shaped bracket is fixedly installed with a fifth electric push rod 49. The telescopic end of the fifth electric push rod 49 is fixedly installed with a push knife 50. The bottom of the C-shaped bracket is fixedly installed with a positioning seat 44.

[0021] When the second dual-axis motor 40 is driven, the push knife 50 can be carried to move longitudinally, but the push knife 50 is moved to a position with a wider space, so that the push knife 50 can be replaced. When performing the pin insertion operation, when the pin moves to the front side of the push knife 50, since the position of the pin corresponds to the position of the push knife 50, the fifth electric push rod 49 is driven, causing the push knife 50 to move horizontally, directly pushing the push knife 50 to move horizontally and insert the plastic part.

[0022] like Figure 3 As shown, the needle loading mechanism 7 includes a conveying roller 11, a feeding belt 12, a mounting frame 13, a needle bin 14, a support rod 15, a first motor 16 and a needle groove 17. The conveying roller 11 is rotatably installed on the front and rear inner walls of the mounting frame 13, and the feeding belt 12 is sleeved on the conveying roller 11. The outer wall of the feeding belt 12 is provided with several groups of needle grooves 17 arranged at equal distances, and the needle groove 17 matches a single needle. The first motor 16 is fixedly installed on the rear side of the mounting frame 13, and the output end of the first motor 16 transversely passes through the mounting frame 13 and is fixedly connected to the rotating shaft of the conveying roller 11. The needle bin 14 is fixedly installed on the top of the mounting frame 13, and the needle bin 14 is placed at an angle. The bottom of the needle bin 14 is horizontally arranged with the outer wall of the feeding belt 12, and the outer wall of the needle bin 14 is fixedly installed with a support rod 15 for stable support.

[0023] First of all, it should be noted that the width of the needle bin 14 is the same as the length of the pin. When a pin is added to the needle bin 14, the first motor 16 drives the conveyor roller 11 to rotate, causing the needle groove 17 on the feed belt 12 to carry the pin to the outside of the needle bin 14, thereby achieving the effect of feeding a single pin.

[0024] like Figure 11 As shown, the plastic part feeding channel 10 includes a channel 51, a base 52, a plastic part feeding trough 53 and a clamping groove 54. The channel 51 is fixedly installed on the top of the base 52. One end of the channel 51 is externally connected to an automatic feeding vibration plate. The other end of the channel 51 is a closed structure. A plastic part feeding trough 53 is provided on the channel 51. The width of the plastic part feeding trough 53 matches the plastic part. A clamping groove 54 is provided at the closed end of the channel 51. The clamping groove 54 is used to cooperate with the grabbing mechanism 9 to grab the plastic part.

[0025] When the external vibrating loading tray feeds the plastic parts into the flow channel 51, the other end of the flow channel 51 is a closed structure, causing the plastic parts to stagnate in the flow channel 51. At this time, due to the presence of the clamping groove 54, the grabbing mechanism 9 can effectively clamp a single plastic part for operation.

[0026] like Figure 4 、 Figure 5 and Figure 6As shown, the grabbing mechanism 9 includes a mounting plate 18, a first electric push rod 19, a fixed block 21, a first slide 20, a first dual-axis motor 25, a first threaded rod 22, a first slider 23, a claw clamp 24, a connecting plate 26, a second motor 27, a third motor 28 and a mounting slot 29. The telescopic end of the first electric push rod 19 is fixedly mounted with a connecting plate 26, and the free end of the connecting plate 26 is rotatably mounted with the mounting plate 18. The top of the connecting plate 26 is fixedly mounted with a second motor 27, and the output end of the second motor 27 longitudinally passes through the connecting plate 26 and is fixedly connected to the rotating shaft of the mounting plate 18. Fixed blocks 21 are rotatably mounted on both ends of the mounting plate 18. The top of the mounting plate 18 is located above the fixed block 21 and is provided with a mounting slot 29. The third motor 28 is fixedly mounted in the mounting slot 29. The third motor 2 The output end of 8 longitudinally passes through the mounting groove 29 and is fixedly connected to the rotating shaft of the fixed block 21. A first slide groove 20 is provided at the bottom of the fixed block 21. A first dual-axis motor 25 is fixedly installed at the center of the inner top of the first slide groove 20. The output end of the first dual-axis motor 25 is fixedly installed with a first threaded rod 22. The free end of the first threaded rod 22 is rotatably connected to the inner walls on both sides of the first slide groove 20. The first slide groove 20 has a first slider 23 built in. The number of first sliders 23 is two groups and they are located at the inner walls on both sides of the first slide groove 20 in sequence. The two groups of first sliders 23 are sleeved on the first threaded rod 22 and threadedly connected to the first threaded rod 22. The built-in threads of the two groups of first sliders 23 are oppositely arranged. A claw clamp 24 is fixedly installed at the bottom of the first slider 23, and the claw clamp 24 matches the clamping groove 54.

[0027] When performing the material grabbing operation, the first electric push rod 19 is driven first. At this time, the third motor 28 drives the adjustment of the position of the claw clamp 24 to correspond to the clamping groove 54. When the first electric push rod 19 moves, the claw clamp 24 can be inserted into the clamping groove 54 for clamping. When the first electric push rod 19 is reset, the second motor 27 is driven to move the claw clamp 24 that grabs the plastic part to the pin base 8. At this time, the operation of the first electric push rod 19 is repeated to complete the placement operation of the plastic part.

[0028] like Figure 7 and Figure 8As shown, the pin base 8 includes a plastic part fixing groove 30, a push plate 31, a second electric push rod 32, a third electric push rod 33, a fourth motor 34, a placement block 35, a second slide groove 36, a fixing plate 37, a second threaded rod 38 and a second slider 39. The third electric push rod 33 is located on one side of the plastic part feeding channel 10. A placement block 35 is provided on the telescopic end of the third electric push rod 33. The placement block 35 is provided with a plastic part fixing groove 30. The rear side of the plastic part fixing groove 30 is open, and the plastic part fixing groove 30 matches the plastic part. The inner walls on both sides of the plastic part fixing groove 30 are provided with groove bodies matching the claw clamp 24. A push plate 31 is slidably installed on the front inner wall of the plastic part fixing groove 30. The second electric push rod 32 is fixedly installed on the rear side of the plastic part fixing groove 30. The telescopic end of the second electric push rod 32 is fixedly connected to the push plate 31. The plastic part fixing groove 30 is located on the front side of the pin insertion mechanism 6 and the needle feeding mechanism 7.

[0029] When the pin insertion operation begins, the position of the plastic part is fixed, so the pins can be effectively aligned to avoid crooked insertion. When the pin insertion is completed, the second electric push rod 32 drives the push plate 31, causing the push plate 31 to push the plastic part out of the plastic part fixing groove 30 to complete the material removal.

[0030] like Figure 2 As shown, the third electric push rod 33 is rotatably connected to the frame 2, and a drive motor is fixedly installed on the frame 2. The output end of the drive motor longitudinally passes through the frame 2 and is fixedly connected to the rotating shaft of the third electric push rod 33.

[0031] The rotating third electric push rod 33 can effectively adjust the unloading position of the plastic part.

[0032] like Figure 7 and Figure 8 As shown, the telescopic end of the third electric push rod 33 is fixedly installed with a fixed plate 37, and a second slide groove 36 is opened at the top of the fixed plate 37. Second threaded rods 38 are rotatably installed on the inner walls of both sides of the second slide groove 36. A fourth motor 34 is fixedly installed on one side wall of the fixed plate 37. The output end of the fourth motor 34 passes through the fixed plate 37 horizontally and is fixedly connected to the second threaded rod 38. The second slide groove 36 has a second slider 39 built in. The second slider 39 is located in the center of the second slide groove 36. The second slider 39 is sleeved on the second threaded rod 38 and is threadedly connected to the second threaded rod 38. The top of the second slider 39 is fixedly connected to the placement block 35.

[0033] The movable placement block 35 can adapt to the pin insertion position of the plastic part during the pin insertion operation, so that the plastic part meets the pin insertion finished product requirements.

[0034] Working principle: During operation, the needle bin 14 is added with the pins first, and the plastic part feeding channel 10 is connected to the external vibrating feeding tray. When the operation is in progress, the external vibrating feeding tray feeds the plastic parts into the channel 51. Since the other end of the channel 51 is a closed structure, the plastic parts can stagnate in the channel 51. At the same time, the first motor 16 drives the conveyor roller 11 to rotate, causing the needle groove 17 on the feeding belt 12 to move with the pins to the outside of the needle bin 14. When the first electric push rod 19 is driven, the third motor 28 drives the adjustment claw clamp 24 to correspond to the clamping groove 54. When the first electric push rod 19 is driven, the third motor 28 drives the adjustment claw clamp 24 to correspond to the clamping groove 54. When it moves, the claw clamp 24 can be inserted into the clamping groove 54 for clamping. When the first electric push rod 19 is reset, the second motor 27 is driven to cause the claw clamp 24 that grabs the plastic part to move to the pin base 8. At this time, when the pin moves to the front side of the push knife 50, since the position of the pin corresponds to the position of the push knife 50, the fifth electric push rod 49 is driven to cause the push knife 50 to move horizontally, directly pushing the push knife 50 to move horizontally to insert the plastic part, completing the pin insertion operation. After the pin insertion is completed, the push plate 31 is driven by the second electric push rod 32, causing the push plate 31 to push the plastic part out of the plastic part fixing groove 30 to complete the material removal.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
