Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, specifically to an easily adjustable circuit board dispensing machine. Background Technology

[0002] Utility model patent CN222132427U discloses a circuit board dispensing device, including two support plates; each support plate has an L-shaped plate fixedly attached to it, and the two L-shaped plates are fitted with a fixing plate. A pneumatic cylinder is mounted on the fixing plate, and a pneumatic rod is fitted to the actuating end of the pneumatic cylinder. A dispensing head is fixedly attached to the bottom end of the pneumatic rod, and a push plate is fixedly attached to the dispensing head. A vertical plate is fixedly attached to one side of the bottom of the fixing plate, and a fixing seat is mounted on the vertical plate. A swing scraper is rotatably mounted in the fixing seat through a pin shaft, and a spring is fixedly connected between the swing scraper and the vertical plate. A collection box is fixedly attached to the other side of the bottom of the fixing plate, and a rectangular inlet is opened on one side of the collection box. When in use, this device can prevent the dispensing head from clogging, and can also avoid glue leakage and overflow, thus preventing excessive glue residue on the surface of the circuit board and ensuring the conductivity of the circuit board.

[0003] However, the device still has some shortcomings in use: the lack of left and right limiters during the movement of the circuit board causes positional deviation during the conveying process, making it difficult to accurately align the dispensing head with the dispensing position during the dispensing process. At the same time, the friction between the circuit board and the conveyor belt is small at the moment the conveyor belt starts and stops, which makes it easy for relative sliding to occur between the circuit board and the conveyor belt, thus affecting the stability of the circuit board movement. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable circuit board dispensing machine, which solves the problem of the lack of left and right limiters during the movement of the circuit board, which causes positional deviation during the conveying process and makes it difficult to accurately align the dispensing head with the dispensing position. At the same time, the friction between the circuit board and the conveyor belt is small at the moment of starting and stopping the conveyor belt, which makes it easy for relative sliding to occur between the circuit board and the conveyor belt, thus affecting the stability of the circuit board movement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable circuit board dispensing machine, comprising a frame, a conveyor roller rotatably connected inside the frame, a conveyor belt rotatably connected outside the conveyor roller, a guide mechanism provided on the frame, a bracket fixedly connected to the upper end of the frame, a conveying mechanism provided on the bracket, a dispensing head provided on the conveying mechanism, a conveying pump provided on the conveying mechanism, and a conveying telescopic hose of the conveying pump fixedly connected to the dispensing head.

[0006] Preferably, the guiding mechanism includes a side plate, which is fixedly connected to the lower end of the frame. A motor is fixedly mounted on the surface of the side plate, and the motor's shaft passes through the side plate and is rotatably connected to it. A bidirectional screw is fixedly connected to the end of the motor's shaft, and the bidirectional screw is rotatably connected to the side plate. A sliding plate is threadedly connected to the outer side of the bidirectional screw, and a guide plate is fixedly connected to the upper end of the sliding plate. By driving the bidirectional screw to rotate and the sliding plate to perform threaded movement, the sliding plate moves the guide plate, thereby changing the distance between the two guide plates. This guides the circuit board during its movement, preventing the circuit board from shifting position and affecting the dispensing process.

[0007] Preferably, the slide plate and the frame are slidably connected, and the guide plate and the frame are slidably connected. The guide plate guides the movement of the circuit board.

A cylinder is fixedly mounted to the lower end of the slide block, and an mounting plate is fixedly connected to the lower end of the cylinder rod. A pressure plate is slidably connected to the outer side of the mounting plate, and the pressure plate is slidably connected to the support. The pressure plate is fixedly mounted to a conveying pump, and the conveying pump's telescopic hose passes through the pressure plate and is fixedly connected to it. The mounting plate is fixedly connected to a dispensing head, and a hanging rod is slidably connected inside the pressure plate. A hanging plate is fixedly connected to the lower end of the hanging rod, and a spring is provided on the outer side of the hanging rod. The motor drives the screw to rotate and the adjusting plate to make a spiral motion, which in turn causes the slide to move the cylinder, which in turn causes the mounting plate to move the dispensing head to move its position, making the dispensing position easy to adjust. At the same time, the cylinder drives the mounting plate to move, which in turn causes the pressure plate to move and compress the spring, which in turn causes the hanging plate to move the pressure roller, which in turn causes the pressure belt to elastically squeeze the circuit board onto the conveyor belt for transport, making the circuit board transport more stable.

[0009] Preferably, the screw and the support plate are rotatably connected, and the screw and the adjusting plate are threadedly connected. The movement of the adjusting plate is controlled by the screw.

[0010] Preferably, one end of the spring is fixedly connected to the pressure plate, and the other end of the spring is fixedly connected to the hanging plate. By setting the spring, the hanging plate is elastically pressed down.

[0011] Preferably, a pressure roller is provided inside the hanging plate, and a pressure belt is provided outside the pressure roller. By providing the pressure roller and pressure belt, the circuit board is elastically compressed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses an electric motor to drive a bidirectional screw to rotate and a sliding plate to make a threaded motion, which in turn causes the sliding plate to move the guide plate, thereby changing the distance between the two guide plates. This guides the circuit board during its movement, preventing the circuit board from shifting position and affecting the dispensing of the device.

[0014] 2. This utility model uses a motor to drive a screw to rotate and an adjusting plate to make a threaded movement, which in turn causes the slide to move the cylinder, which in turn causes the mounting plate to move the dispensing head to move its position, making the dispensing position easy to adjust. At the same time, the cylinder drives the mounting plate to move, which in turn causes the pressure plate to move and compress the spring, which in turn causes the hanging plate to move the pressure roller, which in turn causes the pressure belt to elastically squeeze the circuit board onto the conveyor belt for transport, making the circuit board transport more stable.

[0023] Please see Figures 1-3 The guiding mechanism 4 includes a side plate 41. The lower end of the frame 1 is fixedly connected to the side plate 41. A motor 42 is fixedly mounted on the surface of the side plate 41. The rotating shaft of the motor 42 passes through the side plate 41 and is rotatably connected to the side plate 41. The end of the rotating shaft of the motor 42 is fixedly connected to a bidirectional screw 43. The bidirectional screw 43 is rotatably connected to the side plate 41. The outer side of the bidirectional screw 43 is threadedly connected to a slide plate 44. The upper end of the slide plate 44 is fixedly connected to a guide plate 45. The slide plate 44 is slidably connected to the frame 1, and the guide plate 45 is slidably connected to the frame 1. By setting the guide plate 45, the movement of the circuit board is guided. The motor 42 drives the bidirectional screw 43 to rotate and the slide plate 44 to make threaded movements, thereby causing the slide plate 44 to drive the guide plate 45 to move, thereby changing the distance between the two guide plates 45, thus guiding the circuit board during movement and preventing the circuit board position from shifting and affecting the dispensing of the device.

[0024] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5The conveying mechanism 6 includes a slide 61, which is slidably connected to the outer side of the support 5. An adjusting plate 62 is fixedly connected to the upper end of the slide 61. A support plate 63 is fixedly connected to the upper end of the support 5. A motor 64 is fixedly mounted on the surface of the support plate 63. The output end of the motor 64 passes through the support plate 63 and is rotatably connected to it. A screw 65 is fixedly connected to the end of the output end of the motor 64. The screw 65 is rotatably connected to the support plate 63, and the screw 65 is threadedly connected to the adjusting plate 62. The adjusting plate 62 is moved by the screw 65. A cylinder 66 is fixedly installed at the lower end of the slide block 61. A mounting plate 67 is fixedly connected to the lower end of the cylinder rod of the cylinder 66. A pressure plate 68 is slidably connected to the outside of the mounting plate 67. The pressure plate 68 is slidably connected to the bracket 5. The pressure plate 68 is fixedly installed to the conveying pump 8. The conveying telescopic hose of the conveying pump 8 passes through the pressure plate 68 and is fixedly connected to the pressure plate 68. The mounting plate 67 is fixedly connected to the dispensing head 7. A hanging rod 69 is slidably connected inside the pressure plate 68. A hanging plate 610 is fixedly connected to the lower end of the rod 69. A spring 611 is provided on the outside of the rod 69. One end of the spring 611 is fixedly connected to the pressure plate 68, and the other end of the spring 611 is fixedly connected to the hanging plate 610. By setting the spring 611, the hanging plate 610 is elastically pressed down. A pressure roller 612 is provided inside the hanging plate 610, and a pressure belt 613 is provided on the outside of the pressure roller 612. By setting the pressure roller 612 and the pressure belt 613, the circuit board is elastically squeezed. The motor 64 drives the screw 65 to rotate and the adjusting plate 62 to make threaded movement, which in turn causes the slide 61 to drive the cylinder 66 to move, which in turn causes the mounting plate 67 to drive the dispensing head 7 to move, making the dispensing position easy to adjust. At the same time, the cylinder 66 drives the mounting plate 67 to move, which in turn causes the pressure plate 68 to move and squeeze the spring 611, which in turn causes the hanging plate 610 to drive the pressure roller 612 to move, which in turn causes the pressure belt 613 to elastically squeeze the circuit board onto the conveyor belt 3 for conveying, making the conveying of the circuit board more stable.

[0025] The specific implementation process of this utility model is as follows: In use, the circuit board is placed on the conveyor belt 3, and then the cylinder 66 is started. The cylinder 66 drives the cylinder rod to extend, which in turn moves the mounting plate 67. The mounting plate 67 moves the pressure plate 68, which in turn squeezes the spring 611. The spring 611 squeezes the hanging plate 610, which in turn moves the pressure roller 612. This causes the pressure roller 612 to move the pressure belt 613, which in turn presses the circuit board onto the conveyor belt 3. Then, the conveyor roller 2 is started to drive the conveyor belt 3 to rotate, which in turn moves the circuit board. The motor 42 is started, which drives the bidirectional screw 43 to rotate. The bidirectional screw 43 rotates and moves in a threaded motion with the slide plate 44, which in turn causes the slide plate 44 to move the guide plate 45. This causes the distance between the two guide plates 45 to change. When the circuit board moves to contact the guide plate 45, the movement of the circuit board is corrected and guided. The motor 42 drives the bidirectional screw 43 to rotate and the slide plate 44 to make a threaded motion, which in turn causes the slide plate 44 to move the guide plate 45, thereby changing the distance between the two guide plates 45. This guides the circuit board during its movement, preventing the circuit board from shifting position and affecting the dispensing of the device. Then, the motor 64 drives the screw 65 to rotate and the adjusting plate 62 to make a threaded motion, which in turn causes the slide block 61 to move the cylinder 66, which in turn causes the mounting plate 67 to move the dispensing head 7, making the dispensing position easy to adjust. At the same time, the cylinder 66 drives the mounting plate 67 to move, which in turn causes the pressure plate 68 to move and compress the spring 611, which in turn causes the hanging plate 610 to move the pressure roller 612, which in turn causes the pressure belt 613 to elastically compress the circuit board onto the conveyor belt 3 for conveying, making the conveying of the circuit board more stable. At the same time, the dispensing head 7 moves down to contact the circuit board and dispenses glue at the contact point.
