Description

Technical Field

[0001] The present invention relates to the technical field of power component installation, and in particular to a power component substrate packaging device. Background Art

[0002] Electrical equipment often has a large number of electrical components installed, which enable the circuit to have multiple states. A complex circuit has a large number of electrical components. In order to make the circuit and various electrical components neatly installed and easy to manage, it is necessary to concentrate these electrical components on the same substrate, which can be a metal plate or a PCB circuit board.

[0003] Unlike general electronic components, power components are larger in size and heavier in weight, so the terminal wires used are thicker. When power components are assembled on the substrate, the components themselves will be attached to the substrate. When power components are powered on, they do more work and generate higher heat. If the components themselves are attached to the substrate, the heat will not be released quickly, which will affect the service life. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a power component substrate packaging device, including a substrate and a packaging device, the packaging device including a carrier, a bracket assembly, a drive assembly and a positioning tube, the carrier is a rectangular block, a magnet is provided on the back of the carrier, a positioning plate is provided on the left side of the carrier, the carrier is adsorbed on the substrate by the magnet on the back, and the positioning plate is abutted against the left side of the substrate, and under the positioning of the positioning plate, the carrier is horizontally on the front of the substrate, a first positioning hole is opened on the left side of the positioning plate and passes through the right side of the carrier, the bracket assembly includes a first bracket fixed on the front of the carrier, the first bracket is vertically downward, the drive assembly includes a driving wheel transferred to the bottom end of the first bracket, and also includes The invention relates to a motor mounted on the carrier, a driving wheel mounted on the motor, the bracket assembly further comprising a second bracket mounted on the bottom surface of the carrier and bent downward and to the vicinity of the lower side of the driving wheel, and a third bracket mounted on the second bracket, a reel mounted on the third bracket, the driving assembly further comprising a driven wheel mounted on the reel and transmission-connected to the driving wheel, a second positioning hole is provided on the second bracket, the positioning tube is wound on the reel, a release end of the positioning tube passes through the second positioning hole and reaches the driving wheel, enters the first positioning hole after being transported by the driving wheel, and is finally transported to the front of the substrate after being guided by the first positioning hole, and an external pull switch is connected to the motor through a flexible power cord;

[0005] The encapsulation device further includes a secondary correction mechanism. When the positioning tube is wound around the reel, it loses the restriction of the secondary correction mechanism and becomes flat. When the positioning tube releases length outward from the reel, it becomes tubular through the secondary correction mechanism.

[0006] Further preferably, a notch is provided along the length direction on the pipeline of the positioning tube, and closing parts are left at both ends of the positioning tube. The closing parts at both ends close both ends of the notch.

[0007] Further preferably, the secondary correction mechanism includes a correction block fixed on the positioning plate. The correction block is circular. The correction block extends downward into the first positioning hole. A diameter-changing part is provided at the connection between the correction block and the positioning plate. When the positioning tube enters the carrier from the first positioning hole, the front and rear sides of the notch of the positioning tube pass through the front and rear surfaces of the diameter-changing part. The lumen of the positioning tube communicates with the correction block, and the edge of the correction block is provided with a fillet.

[0008] Further preferably, the carrier is made of plastic, the driving wheel, the driven wheel, the driving pulley and the reel are all plastic wheels, and the first bracket, the second bracket and the third bracket are all plastic brackets.

[0009] Further preferably, the bottom end of the second bracket is provided with a horizontally bent part that bends to the left. The second positioning hole is provided on the horizontal part of the second bracket, and the second positioning hole is close to the position between the driving wheel and the reel.

[0010] Further preferably, a driving groove is provided on the driving wheel. The left side of the driving groove and the left side surface of the positioning plate are on the same vertical plane, so that the release end of the positioning tube vertically penetrates upward from the second positioning hole, then horizontally enters the first positioning hole, and penetrates out from the right end of the carrier.

[0011] Further preferably, the motor is fixed to the bottom of the carrier through a bracket, and the motor is located between the second bracket and the first bracket.

[0012] Further preferably, a charging seat is provided on the carrier, and the motor and the external pull switch are electrically connected to the charging seat.

[0013] The beneficial effects of the present invention compared with the prior art are:

[0014] 1. Use a magnet to adsorb the carrier on the substrate, and use the carrier to install the entire packaging device at a corner of the substrate as shown in the figure. Press the button on the pull switch to start the motor, so that the positioning tube is released onto the front of the substrate, which is equivalent to setting a forward-protruding support on the front of the substrate. Before installing the power components on the substrate, lean the back of the component against the positioning tube, and then connect the pins of the component to the substrate. When the component is installed on the substrate, the back is supported by the positioning tube. Therefore, when the positioning tube retracts, it is equivalent to forming a space between the back of the component and the front of the substrate. Utilizing this space formed between the installed component and the substrate by the positioning tube fully demonstrates that when the component is energized, the back has better air permeability and higher heat dissipation efficiency, thus improving their service life.

[0015] 2. The positioning tube is provided with a notch, which is opened along the length direction of the positioning tube. Therefore, the positioning tube can radially contract in the radial direction, so that when the positioning tube releases its length successively through the second positioning hole and the first positioning hole, it can avoid being tightly fixed in the second positioning hole and the first positioning hole, resulting in obstacles to the release of the length of the positioning tube.

[0016] The opening of the notch also makes the positioning tube become flat when it is wound onto the reel, thus reducing the space. When the positioning tube releases its length outward, it returns to the tubular shape again. Considering that the positioning tube needs to release a longer length when recovering from the flat shape to the tubular shape, a secondary correction mechanism is also provided in the first positioning hole. As the positioning tube releases its length into the first positioning hole, the lumen of the positioning tube passes through the correction block and is quickly corrected into a circular tube by the correction block. The notch of the positioning tube passes through the diameter-changing part and is quickly corrected into a wide notch by the diameter-changing part, so as to ensure that the part of the positioning tube released onto the front of the substrate is a circular tube, with sufficient support conditions to support enough space between the back of the component and the front of the substrate for the component to dissipate heat.

Specific embodiments

[0025] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments.

[0026] In one embodiment, as Figures 1 - 7 shown:

[0027] This embodiment provides a power component substrate packaging device, including a substrate 1 and a packaging device 2. In the power industry, the substrate 1 is fixed in an electrical cabinet as a mounting plate for various power components, and is provided with mounting holes, or the mounting holes are opened on site by an electric screwdriver when installing power components. The packaging device 2 plays an auxiliary role when the power components are installed on the substrate 1. The packaging device 2 includes a carrier 3, a bracket assembly 4, a drive assembly 5, and a positioning tube 6. The carrier 3 is a rectangular block, and a magnet 7 is provided on the back of the carrier 3. A positioning plate 8 is provided on the left side of the carrier 3. The carrier 3 is adsorbed on the substrate 1 through the magnet 7 on the back, and the positioning plate 8 is placed against the left side of the substrate 1. Under the positioning of the positioning plate 8, the carrier 3 is horizontally placed on the front of the substrate 1. A first positioning hole 9 is opened on the left side of the positioning plate 8 and passes through the right side of the carrier 3. The bracket assembly 4 includes a first bracket 10 fixed on the front of the carrier 3, and the first bracket 10 is vertically downward. The drive assembly 5 includes a drive wheel 11 connected to the bottom end of the first bracket 10, and also includes a motor 12 installed on the carrier 3, and also includes a motor 12 installed on the motor 12. The driving wheel 13, the bracket assembly 4 also includes a second bracket 15 installed on the bottom surface of the carrier 3 and bent downward and near the bottom of the driving wheel 11, and also includes a third bracket 16 installed on the second bracket 15, and a reel 17 is installed on the third bracket 16. The driving assembly 5 also includes a driven wheel 14 installed on the reel 17 and drivingly connected to the driving wheel 13. The second bracket 15 is provided with a second positioning hole 18, and the positioning tube 6 is wound on the reel 17. The release end of the positioning tube 6 passes through the second positioning hole 18 and reaches the driving wheel 11. After being transported by the driving wheel 11, it enters the first positioning hole 9, and finally is guided by the first positioning hole 9 and transported to the front of the substrate 1. The motor 12 is connected to an external pull switch 19 through a flexible power cord;

[0028] The packaging device 2 also includes a secondary correction mechanism 20. When the positioning tube 6 is wound on the reel 17, it loses the restriction of the secondary correction mechanism 20 and becomes flat. When the positioning tube 6 is released from the reel 17, it becomes a tube through the secondary correction mechanism 20.

[0029] Further preferably, a notch 23 is opened along the length direction of the pipeline of the positioning tube 6 , and closing parts 24 are left at both ends of the positioning tube 6 , and the closing parts 24 at both ends close both ends of the notch 23 .

[0030] Further preferably, the secondary correction mechanism 20 includes a correction block 25 fixed on the positioning plate 8, the correction block 25 is circular, and the correction block 25 extends downward into the first positioning hole 9. A reducing portion 26 is provided at the connection between the correction block 25 and the positioning plate 8. When the positioning tube 6 enters the carrier 3 from the first positioning hole 9, the front and rear sides of the notch 23 of the positioning tube 6 pass through the front and rear sides of the reducing portion 26, and the lumen of the positioning tube 6 passes through the correction block 25. The edges of the correction block 25 are provided with rounded corners.

[0031] Further preferably, the carrier 3 is made of plastic, and the driving wheel 11, the driven wheel 14, the driving wheel 13 and the winding wheel 17 are all plastic wheels, and the first bracket 10, the second bracket 15 and the third bracket 16 are all plastic brackets.

[0032] Further preferably, the bottom end of the second bracket 15 is provided with a horizontally bent portion 22 that bends to the left, and the second positioning hole 18 is opened on the horizontally bent portion 22 of the second bracket 15, and the second positioning hole 18 is close to the space between the driving wheel 11 and the winding wheel 17.

[0033] Further preferably, a driving groove 21 is formed on the driving wheel 11, and the left side of the driving groove 21 and the left side surface of the positioning plate 8 are located on the same vertical plane, so that the release end of the positioning tube 6 vertically penetrates upward from the second positioning hole 18, then horizontally enters the first positioning hole 9, and penetrates out from the right end of the carrier 3.

[0034] Further preferably, the motor 12 is fixed to the bottom of the carrier 3 through a bracket, and the motor 12 is located between the second bracket 15 and the first bracket 10.

[0035] Further preferably, the carrier 3 is provided with a charging seat, and the motor 12 and the external pull switch 19 are electrically connected to the charging seat.

[0036] Working principle and effect: When installing electrical components on the substrate 1, the carrier 3 is adsorbed on the substrate 1 by using the magnet 7, and the entire packaging device 2 is pressed by the carrier 3. Figure 1It is installed at a corner of the substrate 1 in the shown manner. At this time, the right side of the positioning plate 8 is closely attached to the left side of the substrate 1. Under the positioning of the positioning plate 8, the carrier 3 is horizontal on the front of the substrate 1. Press the button on the external pull switch 19 (prior art) to start the motor 12. The motor 12 drives the driving wheel 13 to rotate. The driving wheel 13 drives the driven wheel 14 to rotate through a belt drive relationship. The driven wheel 14 drives the winding wheel 17 to rotate, so that the positioning tube 6 wound on the winding wheel 17 releases length upward. When the positioning tube 6 releases length upward, it is guided upward through the second positioning hole 18. When the positioning tube 6 releases length upward, it is also conveyed upward through the driving wheel 11. The top section of the positioning tube 6 releases length to the right under the guidance of the first positioning hole 9 in the carrier 3 to ensure that the top section of the positioning tube 6 releases horizontally to the right along the front of the substrate 1. Considering that when electrical components are installed on the substrate 1, the back often closely adheres to the front of the substrate 1, which affects the heat dissipation efficiency when powered on. Therefore, the positioning tube 6 is released onto the front of the substrate 1, which is equivalent to setting a forward convex support on the front of the substrate 1. Before installing the electrical component (hereinafter simply referred to as the component for convenience) on the substrate 1, lean the back of the component against the positioning tube 6, and then connect the pins (or terminal wires) of the component to the substrate 1 (generally, the component has at least two or two rows of pins up and down). When the component is installed on the substrate 1, the back is supported by the positioning tube 6. Therefore, when the positioning tube 6 retracts, it is equivalent to forming a space between the back of the component and the front of the substrate 1. Utilizing the space formed between the installed component and the substrate 1 by the positioning tube 6 fully reflects that when the component is powered on, the back has better air permeability and higher heat dissipation efficiency, thus improving their service life.

[0037] Continuing from the above, since the winding wheel 17 can continue to release the positioning tube 6, the top section of the positioning tube 6 will also release length to the right along the front of the substrate 1 to adapt to the installation of multiple components on the substrate 1. Through the above installation method, it is also possible to form a breathable space on the backs of multiple installed components.

[0038] As described above, since the positioning tube 6 is provided with a notch 23 which is opened along the length direction of the positioning tube 6, the positioning tube 6 can radially contract in the radial direction. In this way, when the positioning tube 6 sequentially passes through the second positioning hole 18 and the first positioning hole 9 to release its length, it can avoid being tightly fixed in the second positioning hole 18 and the first positioning hole 9, resulting in an obstacle to the release of the length of the positioning tube 6. In addition, the opening of the notch 23 also makes the positioning tube 6 become flat (crushed) when it is wound onto the reel 17, thus reducing the space. When the positioning tube 6 releases its length outwards, it returns to the tubular shape again. However, considering that the positioning tube 6 needs to release a longer length when it returns from the flat shape to the tubular shape, a secondary correction mechanism 20 is provided in the first positioning hole 9. As the positioning tube 6 releases its length into the first positioning hole 9, the lumen of the positioning tube 6 passes through the correction block 25 and is quickly corrected into a circular tube by the correction block 25. The notch 23 of the positioning tube 6 passes through the diameter-changing part 26 and is quickly corrected into a wide notch by the diameter-changing part 26, so as to ensure that the part of the positioning tube 6 released onto the front surface of the substrate 1 is a circular tube, and there is sufficient support condition to support enough space between the back of the component and the front surface of the substrate 1 for the component to dissipate heat.

[0039] As described above, since the entire packaging device 2 is adsorbed on the front surface of the substrate 1 by the magnet 7 and the positioning plate 8 is positioned on the left side of the substrate 1, in this way, after installing a row of components on the front surface of the substrate 1, the packaging device 2 is lowered by one position along the left side of the substrate 1, and then another row of components is installed on the front surface of the substrate 1 by the above installation method.

This embodiment is only for the convenience of describing the solution and is set with relative descriptions with reference to the orientations in the figure. In fact, the specific orientations of the components are based on their actual installation, actual use, and the habitual orientation descriptions of those skilled in the art. This is hereby stated.

It should be understood that the above are only the specific embodiments of the present invention and are not used to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
