Description

Technical Field

[0001] The present invention belongs to the technical field of feeding devices, and specifically relates to a fiber feeding device for circuit board processing. Background Art

[0002] A circuit board is an indispensable component in electronic devices. During the processing and production of circuit boards, fiber materials are required. Fiber materials are an important reinforcing material, which can significantly improve the bending, tensile, and compressive strengths of circuit boards, enabling the circuit boards to withstand greater external forces and pressures. In order to accurately add fiber materials to the circuit board substrate, a feeding device is needed to transport the fiber materials from one area to the inlet of the circuit board processing equipment.

[0003] The patent with the publication number CN212798288U discloses a feeding device for the production of sodium carboxymethylcellulose, including a protective cover. Both ends and both sides of the protective cover are provided with side guard plates. A driving roller is installed between the side guard plates, and a feeding conveyor belt is installed between the driving rollers. One end of the feeding conveyor belt is provided with a feeding hopper. The two sides of the protective cover of this patent are provided with connecting frames, and a support frame is installed at the bottom end of the connecting frame, which facilitates the installation and disassembly of the device. Moreover, both ends and both sides of the protective cover are installed with side guard plates through bolts, and a driving roller is installed between the side guard plates, which facilitates the automatic control of the feeding conveyor belt and convenient automatic feeding control. In addition, a feeding hopper is installed on one side of the top of the protective cover through a connecting seat, which facilitates automatic feeding. The use is convenient. A feeding hopper is installed at one end of the protective cover, and a feeding pipe is installed at the bottom of the feeding hopper, which facilitates automatic feeding control.

[0004] However, the above technical solution still has the following deficiencies in actual application:

[0005] The fiber materials to be fed are placed on the conveyor belt, and the fiber materials enter the inlet as the conveyor belt runs. Generally speaking, the fiber feeding in circuit board processing may involve various different types of fiber materials, such as glass fiber, synthetic fiber, etc. These materials may have different physical and chemical properties. Therefore, in order to meet such processing requirements and improve the feeding efficiency, it is necessary to make the conveyor belt transport multiple fiber materials at one time, and each type of fiber material is placed separately, and multiple material inlets are provided at the end of the conveyor belt, and these inlets are aligned with the multiple fiber materials placed on the conveyor belt to receive different types of materials respectively. However, when multiple fiber materials are placed on the conveyor belt, since the fiber materials may be in a stacked state, when the fiber materials are placed, they may collapse or slide due to the fall, resulting in mixing with the other fiber materials, and thus the materials received by each inlet deviate, affecting the subsequent processing effect of the circuit board.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. A fiber feeding device for circuit board processing according to the present invention uses a feeding auxiliary mechanism to sequentially add different types of fiber materials into a hexagonal enclosure composed of multiple elastic cloths. The fiber materials will only be concentrated in the enclosure. Even if they collapse or slide, it will only be within the enclosure range. Then, according to the position of the input port, the elastic cloth is driven to move. When the elastic cloth moves, it can push the fiber materials in the enclosure so that the fiber materials can be aligned with the input port. When the fiber materials tend to be stable, then the elastic cloth is driven to rise, and the fiber materials move along with the conveyor belt, thus avoiding the situation that when multiple fiber materials are sequentially added to the conveyor belt, the fiber materials are mixed with each other, resulting in deviation of the materials received by each input port and affecting the subsequent processing effect of the circuit board. Moreover, when the fiber materials are added to the hexagonal enclosure composed of elastic cloth and the distribution area is larger than the area of the corresponding input port, the hexagonal enclosure composed of elastic cloth can be driven to become smaller to gather the fiber materials until the distribution area of the fiber materials is smaller than the area of the input port. At this time, the fiber materials are transported again, which can avoid the situation that some fiber materials fall to the ground or into other input ports because the distribution area of the fiber materials on the conveyor belt is larger than the area of the input port, ensuring the smooth addition of the fiber materials. And after the fiber materials are gathered, the fiber materials can be compacted by the first plate and the second plate, and then the elastic cloth is driven to rise away from the fiber materials, which can avoid the situation that after the fiber materials are gathered and the elastic cloth moves away from the fiber materials, the fiber materials collapse again, further ensuring the accurate input of the fiber materials and also avoiding mixing with other fiber materials. And when the elastic cloth moves upward away from the fiber materials, multiple first clamping plates and second clamping plates are driven to descend simultaneously and scrape the surface of the elastic cloth, so that the fiber materials attached to the surface of the elastic cloth can be scraped off, thus ensuring the input amount of the fiber materials and also avoiding the situation that when the elastic cloth is used subsequently, the fiber materials attached to it fall into other fiber materials and are mixed with each other.

[0021] 2. A fiber feeding device for circuit board processing according to the present invention, when the fiber materials are added to the feed hopper, the motor two can be used to drive the stirring rod to rotate to flip the fiber materials by the blades on its surface, thus avoiding the situation that the fiber materials are blocked in the feed hopper and affecting the normal feeding.

[0049] Specifically, when the existing feeding device is in use, the material inlet of the circuit board processing equipment is arranged at the end of the conveyor belt 2. Then, the fiber material to be fed is placed on the conveyor belt 2, and the fiber material enters the inlet as the conveyor belt 2 runs. Generally speaking, the fiber feeding in circuit board processing may involve various types of fiber materials, such as glass fiber, synthetic fiber, etc. These materials may have different physical and chemical properties. Therefore, in order to meet such processing requirements and improve the feeding efficiency, it is necessary to make the conveyor belt 2 transport multiple fiber materials at one time, and each type of fiber material is placed separately. And multiple material inlets are arranged at the end of the conveyor belt 2, and these inlets are aligned with the multiple fiber materials placed on the conveyor belt 2 to receive different types of materials respectively. However, when multiple fiber materials are placed on the conveyor belt 2, since the fiber materials may be in a stacked state, when the fiber materials are placed, they may collapse or slide, resulting in mixing with the other fiber materials, and then the materials received by each inlet deviate, affecting the subsequent processing effect of the circuit board;

[0050] Therefore, to solve the above problems, according to the number of inlets arranged at the end of the conveyor belt 2, different types of fiber materials are sequentially added to the feed hopper 7. The fiber materials are discharged along the discharge pipe 10 at the bottom of the feed hopper 7. And when the fiber materials are discharged, the bottom of the adjusting column 39 is attached to the upper surface of the conveyor belt 2. The fiber materials enter the hexagonal enclosure composed of multiple elastic cloths 18. The fiber materials will only be concentrated in the enclosure. Even if they collapse or slide, it is only within the enclosure range. Then, according to the position of the inlet, the motor seven 34 drives the first threaded rod 3 to rotate, so that the chute plate 4 moves horizontally. With the movement of the elastic cloth 18, when the elastic cloth 18 moves, it can push the fiber materials in the enclosure, so that the fiber materials can be aligned with the inlet. When the fiber materials tend to be stable, then the elastic cloth 18 is driven to rise, and then the position of the elastic cloth 18 is adjusted. Repeating the above operations, another type of fiber material can fall onto the conveyor belt 2. And when each type of fiber material is placed on the upper surface of the conveyor belt 2, it will be intercepted by the elastic cloth 18. And when the fiber materials no longer collapse or slide and tend to be stable, then the elastic cloth 18 is moved away. The conveyor belt 2 drives the fiber materials to move, so that the fiber materials move into the inlet, thus avoiding the situation that when multiple fiber materials are sequentially added to the conveyor belt 2, the fiber materials are mixed with each other, resulting in the deviation of the materials received by each inlet and affecting the subsequent processing effect of the circuit board;

[0051] Since the specifications of the fiber material inlet are fixed, and when the quantity of a certain fiber material is large, its distribution area may be larger than the area of the inlet. Therefore, when the fiber material enters the inlet, some of the fiber material may fall to the ground or into other inlets, causing trouble. So, to avoid this situation, when the fiber material is added to the hexagonal enclosure formed by the elastic cloth 18 and its distribution area is larger than the area of the corresponding inlet, the motor three 16 can be used to drive the rotation of the threaded rod two 17, causing the lifting ring 15 to move upward. The multiple connecting rods 19 rotate simultaneously, causing the multiple adjusting rods 35 to move radially. The multiple adjusting columns 39 also move radially. Since the elastic cloth 18 has a certain elasticity, the hexagonal enclosure formed by the elastic cloth 18 also becomes smaller. When the hexagonal enclosure becomes smaller, it will gather the fiber material until the distribution area of the fiber material is smaller than the area of the inlet. At this time, transporting the fiber material can avoid the situation where some fiber material falls to the ground or into other inlets due to the distribution area of the fiber material on the conveyor belt 2 being larger than the area of the inlet, ensuring the smooth addition of the fiber material;

[0052] Although the gathering of the fiber material can be achieved by shrinking the hexagonal enclosure, after the fiber material is gathered, the elastic cloth 18 is away from the fiber material, and the fiber material may collapse again, which will still affect the accurate input of the fiber material and the situation of mixing with other fiber materials. So, to avoid this situation, after the fiber material is gathered, according to the area of the hexagonal enclosure, the motor six 32 can be used to drive the rotation of the threaded rod five 33, causing the plate two 31 to slide inside the plate one 30, making the end of the plate two 31 close to the inner surface of the elastic cloth 18. Then, the electric push rod 13 can be used to drive the plate one 30 and the plate two 31 to descend, using their lower end faces to compact the fiber material. At the same time, in cooperation with the motor five 29, the plate one 30 and the plate two 31 can be rotated to adjust the compaction angle, so that the fiber material inside the hexagonal enclosure can be evenly compacted. At this time, driving the elastic cloth 18 to rise away from the fiber material can avoid the situation where the fiber material collapses again after the elastic cloth 18 is away from the fiber material after the fiber material is gathered, further ensuring the accurate input of the fiber material and avoiding mixing with other fiber materials;

[0053] Since the elastic cloth 18 has a certain elasticity, fiber materials are likely to adhere to the surface of the elastic cloth 18. When fiber materials adhere to the surface of the elastic cloth 18, it not only affects the input amount of fiber materials but also causes the adhered fiber materials on the elastic cloth 18 to fall into other fiber materials during subsequent use, resulting in a situation of mutual mixing. Therefore, to avoid this situation, when the orientation of the adjusting column 39 is adjusted, the first clamping plate 20 and the second clamping plate 21 will also slide relative to each other to meet the distance between adjacent adjusting columns 39. Moreover, with the cooperation of the sliding column 24 and the spring 41, the first clamping plate 20, the second clamping plate 21 and the elastic cloth 18 are closely attached. Since multiple first clamping plates 20 and second clamping plates 21 are connected by the first connecting block 23 and the second connecting block 40, when the elastic cloth 18 moves upward away from the fiber materials, by simultaneously starting the fourth motor 25 and the eighth motor 36, under the action of the rotation of the fourth threaded rod 28 and the third threaded rod 22, the first connecting block 23 slides on the third sliding rod 27, and the second connecting block 40 slides on the second sliding rod 26. Multiple first clamping plates 20 and second clamping plates 21 descend simultaneously and scrape the surface of the elastic cloth 18, so that the fiber materials adhered to the surface of the elastic cloth 18 can be scraped off, thus ensuring the input amount of fiber materials. At the same time, it also avoids the situation that the fiber materials adhered to the elastic cloth 18 fall into other fiber materials during subsequent use, resulting in mutual mixing.

[0054] In this embodiment, as Figure 2 shown, a stirring rod 9 is rotatably arranged in the middle of the upper end of the feed hopper 7, and a second motor 8 is fixedly connected to the middle of the upper end surface of the feed hopper 7. The output end of the second motor 8 is fixedly connected to the end of the stirring rod 9.

[0055] Specifically, when fiber materials are added to the feed hopper 7, the second motor 8 can be used to drive the stirring rod 9 to rotate, so as to use the blades on its surface to turn the fiber materials, thereby avoiding the situation that the fiber materials are blocked in the feed hopper 7 and affecting normal feeding.

[0056] Working principle: According to the number of input ports set at the end of the conveyor belt 2, different types of fiber materials are sequentially added into the feed hopper 7. The motor two 8 can be used to drive the stirring rod 9 to rotate, and the blades on its surface are used to turn over the fiber materials, thus avoiding the situation that the fiber materials are blocked in the feed hopper 7 and affecting the normal feeding. The fiber materials are discharged through the discharge pipe 10 at the bottom of the feed hopper 7. Moreover, when the fiber materials are discharged, the bottom of the adjusting column 39 fits with the upper surface of the conveyor belt 2. The fiber materials enter the hexagonal enclosure composed of multiple elastic cloths 18. The fiber materials will only be concentrated in the enclosure. Even if they collapse or slide, it is only within the enclosure range. Then, according to the position of the input port, the motor seven 34 is used to drive the first threaded rod 3 to rotate, so that the chute plate 4 moves horizontally, and the elastic cloth 18 moves. When the elastic cloth 18 moves, it can push the fiber materials in the enclosure, so that the fiber materials can be aligned with the input port. When the fiber materials tend to be stable, then the elastic cloth 18 is driven to rise, and then the position of the elastic cloth 18 is adjusted. By repeating the above operations, another type of fiber material can fall onto the conveyor belt 2. Moreover, when each type of fiber material is placed on the upper surface of the conveyor belt 2, it will be intercepted by the elastic cloth 18. And when the fiber materials stop collapsing and sliding and tend to be stable, the elastic cloth 18 is moved away, and the conveyor belt 2 is used to drive the fiber materials to move, so that the fiber materials move into the input port, which can avoid the situation that when multiple types of fiber materials are sequentially added to the conveyor belt 2, the fiber materials are mixed with each other, resulting in deviation of the materials received by each input port and affecting the subsequent processing effect of the circuit board; Since the specifications of the fiber material input ports are fixed, and when the quantity of a certain type of fiber material is large, its distribution area may be larger than the area of the input port. Therefore, when the fiber materials enter the input port, some fiber materials may fall to the ground or other input ports, causing trouble. Therefore, to avoid this situation, when the fiber materials are added to the hexagonal enclosure composed of the elastic cloth 18 and the distribution area is larger than the area of the corresponding input port, the motor three 16 can be used to drive the second threaded rod 17 to rotate, so that the lifting ring 15 moves upward, multiple connecting rods 19 rotate simultaneously, so that multiple adjusting rods 35 move radially along the same direction, and multiple adjusting columns 39 also move radially. Since the elastic cloth 18 has a certain elasticity, the hexagonal enclosure composed of the elastic cloth 18 also becomes smaller. When the hexagonal enclosure becomes smaller, it will gather the fiber materials until the distribution area of the fiber materials is smaller than the area of the input port. At this time, the fiber materials are transported again, which can avoid the situation that some fiber materials fall to the ground or other input ports due to the distribution area of the fiber materials on the conveyor belt 2 being larger than the area of the input port, ensuring the smooth addition of the fiber materials;Although the gathering of fiber materials can be achieved by shrinking the hexagonal enclosure, after the fiber materials are gathered, the elastic cloth 18 is far from the fiber materials, and the fiber materials may collapse again, which will still affect the accurate input of the fiber materials and the situation of mixing with other fiber materials. Therefore, to avoid this situation, after the fiber materials are gathered, according to the area of the hexagonal enclosure, the motor six 32 can be used to drive the rotation of the threaded rod five 33, so that the plate body two 31 slides inside the plate body one 30, and the end of the plate body two 31 approaches the inner surface of the elastic cloth 18. Then, the electric push rod 13 can be used to drive the plate body one 30 and the plate body two 31 to descend, and the lower end surfaces of the two are used to compact the fiber materials. At the same time, in cooperation with the motor five 29, the plate body one 30 and the plate body two 31 can be rotated to adjust the compaction angle, so that the fiber materials in the hexagonal enclosure can be evenly compacted. At this time, driving the elastic cloth 18 to rise away from the fiber materials can avoid the situation that after the fiber materials are gathered, the elastic cloth 18 is far from the fiber materials and the fiber materials collapse again, further ensuring the accurate input of the fiber materials and avoiding mixing with other fiber materials; because the elastic cloth 18 has a certain elasticity, the fiber materials are easily attached to the surface of the elastic cloth 18. When the fiber materials are attached to the surface of the elastic cloth 18, it not only affects the input amount of the fiber materials, but also causes the attached fiber materials on the elastic cloth 18 to fall into other fiber materials during subsequent use, resulting in a mixing situation. Therefore, to avoid this situation, when the orientation of the adjusting column 39 is adjusted, the clamping plate one 20 and the clamping plate two 21 will also slide relative to each other to meet the spacing of adjacent adjusting columns 39. And, with the cooperation of the sliding column 24 and the spring 41, the clamping plate one 20, the clamping plate two 21 and the elastic cloth 18 are closely attached. Since multiple clamping plates one 20 and clamping plates two 21 are connected by the connecting block one 23 and the connecting block two 40, when the elastic cloth 18 moves upward away from the fiber materials, starting the motor four 25 and the motor eight 36 at the same time can, under the action of the rotation of the threaded rod four 28 and the threaded rod three 22, make the connecting block one 23 slide on the slide rod three 27 and the connecting block two 40 slide on the slide rod two 26, and multiple clamping plates one 20 and clamping plates two 21 descend at the same time and scrape the surface of the elastic cloth 18, so that the fiber materials attached to the surface of the elastic cloth 18 can be scraped off, thus ensuring the input amount of the fiber materials and also avoiding the situation that during subsequent use of the elastic cloth 18, the attached fiber materials fall into other fiber materials and mix with each other.;
