Description

Technical Field

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

[0002] Circuit boards are indispensable components of electronic devices. Fiber materials are needed in the processing and production of circuit boards. Fiber materials are an important reinforcing material that can significantly improve the bending, tensile and compressive strength of circuit boards, allowing 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 feed port of the circuit board processing equipment.

[0003] The patent with announcement number CN212798288U discloses a feeding device for sodium carboxymethyl cellulose production, including a protective cover, side guard plates are installed on both sides of both ends of the protective cover, a transmission roller is installed between the side guard plates, a feeding conveyor belt is installed between the transmission rollers, and a feeding hopper is installed at one end of the feeding conveyor belt. The protective cover of the patent is installed with a connecting frame on both sides, and a support frame is installed at the bottom of the connecting frame, through which the installation and disassembly of the control device is convenient, and side guard plates are installed on both sides of both ends of the protective cover by bolts, and a transmission roller is installed between the side guard plates. The feeding conveyor belt is conveniently controlled by the transmission roller, and automatic feeding control is convenient. A feeding hopper is installed on one side of the top of the protective cover through a connecting seat, and automatic feeding is convenient through the feeding hopper. It is easy to use, 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, and automatic feeding control is convenient through the feeding pipe.

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

[0005] The fiber material to be fed is placed on the conveyor belt, and the fiber material enters the feed port as the conveyor belt runs. Generally speaking, the fiber feeding in circuit board processing may involve a variety of 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 needs and improve the feeding efficiency, it is necessary to make the conveyor belt convey a variety of fiber materials at a time, and each fiber material is placed separately, and a plurality of material feed ports are set at the end of the conveyor belt, and these feed ports are aligned with the various fiber materials placed on the conveyor belt to receive different types of materials respectively. However, when a variety of fiber materials are placed on the conveyor belt, since the fiber materials may be in a stacked state, the fiber materials may collapse or slide when they are placed, resulting in mixing with other fiber materials, which in turn causes deviations in the materials received by each feed port, 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 processing a circuit board according to the present invention uses a feeding auxiliary mechanism to sequentially add different kinds of fiber materials into a hexagonal enclosure composed of multiple elastic cloths. The fiber materials will only be concentrated in the enclosure. Even if collapse or sliding occurs, it will only be within the enclosure. Then, according to the position of the feed port, the elastic cloth is driven to move. When the elastic cloth moves, the fiber materials in the enclosure can be pushed so that the fiber materials can be aligned with the feed port. When the fiber materials tend to be stable, the elastic cloth is driven to rise, and the fiber materials move with the conveyor belt, thereby avoiding the situation where the fiber materials are mixed with each other when multiple fiber materials are sequentially added to the conveyor belt, resulting in deviations in the materials received at each feed port, which affects the subsequent processing effect of the circuit board. Moreover, when the fiber materials are added to the hexagonal enclosure composed of the elastic cloth and the distribution area is larger than the corresponding feed port area, the hexagonal enclosure composed of the elastic cloth can be driven to become smaller to gather the fiber materials until the fiber materials are gathered to their distribution points. The area of ​​the cloth is smaller than the area of ​​the input port. At this time, the fiber material can be transported again to avoid the situation where part of the fiber material falls to the ground or other input ports due to the distribution area of ​​the fiber material on the conveyor belt being larger than the area of ​​the input port, thereby ensuring the smooth addition of the fiber material. Moreover, after the fiber material is gathered, the plate body 1 and the plate body 2 can be used to compact the fiber material, and then the elastic cloth can be driven up to move away from the fiber material, thereby avoiding the situation where the elastic cloth moves away from the fiber material after the fiber material is gathered and the fiber material collapses again, further ensuring the accurate input of the fiber material and avoiding mixing with other fiber materials. Moreover, when the elastic cloth moves upward away from the fiber material, multiple clamping plates 1 and 2 are driven to descend at the same time and scrape with the surface of the elastic cloth, so that the fiber material attached to the surface of the elastic cloth can be scraped off, thereby ensuring the input amount of the fiber material. At the same time, it also avoids the situation where the fiber material attached to the elastic cloth falls into other fiber materials and mixes with each other when the elastic cloth is used later.

[0021] 2. The fiber feeding device for circuit board processing described in the present invention can use motor 2 to drive the stirring rod to rotate when the fiber material is added into the feed hopper, so as to use the blades on its surface to turn the fiber material, thereby avoiding the situation where the fiber material is blocked in the feed hopper and affects the normal feeding.

[0049] Specifically, when the existing feeding device is used, the material feeding port of the circuit board processing equipment is set at the end of the conveyor belt 2, and then the fiber material to be fed is placed on the conveyor belt 2, and the fiber material enters the feeding port as the conveyor belt 2 runs. Generally speaking, the fiber feeding in circuit board processing may involve a variety of 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 2 convey a variety of fiber materials at a time, and each fiber material is placed separately, and a plurality of material feeding ports are set at the end of the conveyor belt 2, and these feeding ports are aligned with the various fiber materials placed on the conveyor belt 2 to receive different types of materials respectively. However, when a variety of fiber materials are placed on the conveyor belt 2, since the fiber materials may be in a piled state, the fiber materials may collapse or slide when placed, resulting in mixing with other fiber materials, thereby causing deviations in the materials received by each feeding port, affecting the subsequent processing effect of the circuit board;

[0050] Therefore, in order to solve the above problems, different types of fiber materials are added into the feed hopper 7 in sequence according to the number of input ports set at the end of the conveyor belt 2, and the fiber materials are discharged along the discharge pipe 10 at the bottom of the feed hopper 7. Moreover, when the fiber materials are discharged, the bottom of the adjustment column 39 is in contact with the upper surface of the conveyor belt 2, and the fiber materials enter the hexagonal enclosure composed of multiple elastic cloths 18. The fiber materials will only be concentrated in the enclosure, and even if collapse or sliding occurs, it will only be within the range of the enclosure. Then, according to the position of the input port, the motor 7 34 is used to drive the threaded rod 1 3 to rotate, so that the slide plate 4 moves horizontally, and the elastic cloth 18 is used to move. When the elastic cloth 18 moves, the fiber material in the enclosure can be pushed. The fiber material can be aligned with the input port. When the fiber material tends to be stable, the elastic cloth 18 is driven to rise, and the position of the elastic cloth 18 is adjusted. The above operation is repeated to allow another fiber material to fall onto the conveyor belt 2. Moreover, when each fiber material is placed on the upper surface of the conveyor belt 2, it will be intercepted by the elastic cloth 18. After the fiber material no longer collapses or slides and tends to be stable, the elastic cloth 18 is removed and the fiber material is driven by the conveyor belt 2 to move. The fiber material is moved to the input port, which can avoid the mixing of fiber materials when multiple fiber materials are added to the conveyor belt 2 in sequence, resulting in deviation of the materials received at each input port, which affects 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 fiber material is large, its distribution area may be larger than the area of ​​the inlet, so when the fiber material enters the inlet, part of the fiber material falls to the ground or other inlets, causing trouble. Therefore, in order to avoid this situation, after the fiber material is added to the hexagonal enclosure formed by the elastic cloth 18, and the distribution area is larger than the corresponding inlet area, the motor 3 16 can be used to drive the threaded rod 2 17 to rotate, so that the lifting ring 15 moves upward, and the multiple connecting rods 19 rotate at the same time, so that the multiple adjustment rods 35 move radially at the same time, and the multiple adjustment columns 39 also move radially. Since the elastic cloth 18 has a certain elasticity, the hexagonal enclosure formed by the elastic cloth 18 is also getting smaller. When the hexagonal enclosure becomes smaller, the fiber material will be gathered until the fiber material is gathered to a distribution area smaller than the area of ​​the inlet. At this time, the fiber material is transported again, which can avoid the situation where part of the fiber material falls to the ground or other inlets due to the distribution area of ​​the fiber material on the conveyor belt 2 being larger than the inlet area, thereby ensuring the smooth addition of the fiber material.

[0052] Although the fiber material can be gathered by reducing the hexagonal enclosure, after the fiber material is gathered, the elastic cloth 18 is far 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 mixing with other fiber materials. Therefore, in order to avoid this situation, after the fiber material is gathered, according to the area of ​​the hexagonal enclosure, the motor 6 32 can be used to drive the threaded rod 5 33 to rotate, so that the plate body 2 31 slides inside the plate body 1 30, so that the end of the plate body 2 31 is close to the inner surface of the elastic cloth 18, and then Then, the electric push rod 13 is used to drive the plate body 1 30 and the plate body 2 31 to descend, and the lower end surfaces of the two are used to compact the fiber material. At the same time, the motor 5 29 can be used to rotate the plate body 1 30 and the plate body 2 31 to adjust the compaction angle, so that the fiber material in the hexagonal enclosure can be evenly compacted. At this time, the elastic cloth 18 is driven to rise and move away from the fiber material, which can avoid the situation that the fiber material is gathered and the elastic cloth 18 is away from the fiber material, and the fiber material collapses again, 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, the fiber material is easy to adhere to the surface of the elastic cloth 18. When the fiber material adheres to the surface of the elastic cloth 18, it not only affects the input amount of the fiber material, but also causes the elastic cloth 18 to fall into other fiber materials when it is used later, resulting in mutual mixing. Therefore, in order to avoid this situation, when the orientation of the adjustment column 39 is adjusted, the clamping plate 1 20 and the clamping plate 21 will also slide relatively to meet the spacing between adjacent adjustment columns 39, and under the cooperation of the sliding column 24 and the spring 41, the clamping plate 1 20, the clamping plate 21 and the elastic cloth 18 are tightly fitted, and because a plurality of clamping plates 1 20, the clamping plates 21 They are connected by connecting block one 23 and connecting block two 40. Therefore, when the elastic cloth 18 moves upward away from the fiber material, the motor four 25 and the motor eight 36 are started at the same time, and the connecting block one 23 slides on the sliding rod three 27 and the connecting block two 40 slides on the sliding rod two 26 under the action of the rotation of the threaded rod four 28 and the threaded rod three 22. The multiple splints one 20 and two splints 21 descend at the same time and form a scrape with the surface of the elastic cloth 18, so that the fiber material attached to the surface of the elastic cloth 18 can be scraped off, thereby ensuring the input amount of the fiber material. At the same time, it also avoids the situation where the fiber material attached to the elastic cloth 18 falls into other fiber materials and mixes with each other when the elastic cloth 18 is used later.

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

[0055] Specifically, when the fiber material is added into the feed hopper 7, the motor 2 8 can be used to drive the stirring rod 9 to rotate, so that the blades on its surface can be used to turn the fiber material, thereby avoiding the situation where the fiber material is blocked in the feed hopper 7 and affects the 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 added to the feed hopper 7 in sequence, and the motor 8 can be used to drive the stirring rod 9 to rotate, so as to use the blades on its surface to flip the fiber materials, thereby avoiding the situation where the fiber materials are blocked in the feed hopper 7 and affect the normal material discharge. 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 adjustment column 39 is in contact with the upper surface of the conveyor belt 2, and 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 collapse or sliding occurs, it is only within the enclosure range. Then, according to the input port The motor 7 34 drives the threaded rod 1 3 to rotate, so that the slide plate 4 moves horizontally, and the elastic cloth 18 moves. When the elastic cloth 18 moves, the fiber material in the enclosure can be pushed so that the fiber material can be aligned with the input port. When the fiber material tends to be stable, the elastic cloth 18 is driven to rise, and the position of the elastic cloth 18 is adjusted. Repeating the above operation can make another fiber material fall onto the conveyor belt 2. Moreover, when each fiber material is placed on the upper surface of the conveyor belt 2, it will be intercepted by the elastic cloth 18, and after waiting for the fiber material to no longer collapse or slide and tend to be stable, the elastic cloth 18 is removed, and the conveyor belt 2 is used to drive the fiber material to move, so that the fiber material moves to In the input port, it can be avoided that when multiple fiber materials are added to the conveyor belt 2 in sequence, the fiber materials are mixed with each other, resulting in deviations in the materials received by each input port, affecting the subsequent processing effect of the circuit board; since the specifications of the fiber material input port are fixed, and when the quantity of one fiber material is large, its distribution area may be larger than the area of ​​the input port, so when the fiber material enters the input port, part of the fiber material falls to the ground or other input ports, causing trouble. Therefore, in order to avoid this situation, after the fiber material is added to the hexagonal enclosure composed of the elastic cloth 18, and the distribution area is larger than the corresponding input port area, the motor three 16 belt The movable threaded rod 17 rotates to move the lifting ring 15 upward, and the multiple connecting rods 19 rotate at the same time, so that the multiple adjustment rods 35 move radially at the same time, and the multiple adjustment columns 39 also move radially. Since the elastic cloth 18 has a certain elasticity, the hexagonal enclosure formed by the elastic cloth 18 is also getting smaller. When the hexagonal enclosure becomes smaller, the fiber material will be gathered until the fiber material is gathered to a distribution area smaller than the area of ​​the input port. At this time, the fiber material is transported again to avoid the situation where part of the fiber material falls to the ground or other input ports because the distribution area of ​​the fiber material on the conveyor belt 2 is larger than the input port area, thereby ensuring the smooth addition of the fiber material;Although the fiber material can be gathered by reducing the hexagonal enclosure, after the fiber material is gathered, the elastic cloth 18 is far 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 mixing with other fiber materials. Therefore, in order to avoid this situation, after the fiber material is gathered, according to the area of ​​the hexagonal enclosure, the motor 6 32 can be used to drive the threaded rod 5 33 to rotate, so that the plate body 2 31 slides inside the plate body 1 30, so that the end of the plate body 2 31 is close to the inner surface of the elastic cloth 18, and then the electric push rod 13 is used to drive the plate body 1 30 and the plate body 1 The plate 1 30 and the plate 2 31 are rotated by the motor 5 29 to adjust the compaction angle, so that the fiber material in the hexagonal enclosure can be evenly compacted. At this time, the elastic cloth 18 is driven to rise and move away from the fiber material, which can avoid the situation that the fiber material is gathered and the elastic cloth 18 moves away from the fiber material, and the fiber material collapses again, further ensuring the accurate input of the fiber material and avoiding mixing with other fiber materials. Since the elastic cloth 18 has a certain elasticity, the fiber material is easy to adhere to the surface of the elastic cloth 18. When the fiber material is attached to the surface of the elastic cloth 18, it not only affects the input amount of the fiber material, but also causes the fiber material attached to the elastic cloth 18 to fall into other fiber materials during subsequent use, resulting in mutual mixing. Therefore, in order to avoid this situation, when the orientation of the adjustment column 39 is adjusted, the clamping plate 1 20 and the clamping plate 2 21 will also slide relatively to meet the spacing between adjacent adjustment columns 39, and under the cooperation of the sliding column 24 and the spring 41, the clamping plate 1 20, the clamping plate 21 and the elastic cloth 18 are tightly fitted, and because the plurality of clamping plates 1 20 and the clamping plates 2 21 are connected by the connecting block 1 23 and the connecting block 2 40 Therefore, when the elastic cloth 18 moves upward away from the fiber material, the motor 4 25 and the motor 8 36 are started at the same time, and the connecting block 1 23 slides on the sliding rod 3 27 and the connecting block 2 40 slides on the sliding rod 2 26 under the action of the rotation of the threaded rod 4 28 and the threaded rod 3 22. The multiple clamping plates 1 20 and 21 are simultaneously lowered and scraped against the surface of the elastic cloth 18, so that the fiber material attached to the surface of the elastic cloth 18 can be scraped off, thereby ensuring the input amount of the fiber material. At the same time, it also prevents the fiber material attached to the elastic cloth 18 from falling into other fiber materials and mixing with each other when the elastic cloth 18 is used later. ;
