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, these electrical components need to be concentrated on the same substrate. The substrate can be a metal plate or a PCB circuit board.

[0003] Unlike general electronic components, power components are larger and heavier, so they use thicker terminal wires. When assembled onto a substrate, the components rest against the substrate. When energized, power components perform significant work, generating high temperatures. If the components rest against the substrate, heat is lost and dissipated slowly, shortening their lifespan. Summary of the Invention

The cam is a member of a group of members that is connected to the base frame by a pair of fixed links. The cam is a member of a group of members that is connected to the base frame by a pair of fixed links. The cam is a member of a group of members that is connected to the base frame by a pair of fixed links.

[0005] The packaging device also includes a secondary correction mechanism. When the positioning tube is wound on the reel, it loses the restriction of the secondary correction mechanism and becomes flat. When the positioning tube is released outward from the reel, it becomes tubular through the secondary correction mechanism.

[0006] Further preferably, a notch is opened on the pipeline of the positioning tube along its length direction, and closing parts are left at both ends of the positioning tube, and 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, and the correction block extends downward into the first positioning hole. A reducing portion is provided at the connection between the correction block and the positioning plate. When the positioning tube enters the carrier through the first positioning hole, the front and rear sides of the notch of the positioning tube pass through the front and rear sides of the reducing portion, the lumen of the positioning tube passes through the correction block, and the edge of the correction block is provided with rounded corners.

[0008] Further preferably, the carrier is made of plastic, the driving wheel, the driven wheel, the driving wheel 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 horizontal portion bent to the left, the second positioning hole is opened on the horizontal portion of the second bracket, and the second positioning hole is close to between the driving wheel and the winding wheel.

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

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

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

[0013] The beneficial effects of the present invention compared to 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 on a corner of the substrate as shown in the figure. Press the button on the pull-out switch to start the motor, so that the positioning tube is released to the front of the substrate, which is equivalent to setting a forward-protruding support on the front of the substrate. Before installing the power component on the substrate, the back of the component is placed on the positioning tube, and then the pins of the component are connected to the substrate. When the component is installed on the substrate, the back is supported by the positioning tube. Therefore, when the positioning tube is retracted, it is equivalent to forming a space between the back of the component and the front of the substrate. The space formed between the installed component and the substrate by the positioning tube fully reflects that when the component is energized, the back has good air permeability and high heat dissipation efficiency, which improves their service life.

[0015] 2. A slot is provided on the positioning tube, and the slot is provided along the length direction of the positioning tube, so that the positioning tube can be radially contracted in the radial direction. In this way, when the positioning tube passes through the second positioning hole and the first positioning hole in turn to release the length, it is avoided from being tightly fixed in the second positioning hole and the first positioning hole, which would cause obstacles to the release length of the positioning tube.

[0016] The opening of the notch also makes the positioning tube become flat when it is rolled onto the reel, thereby reducing the space, and when the positioning tube is released outward, it returns to the tubular shape again. Considering that the length of the positioning tube to be released when it is restored from flat to tubular is longer, a secondary correction mechanism is set in the first positioning hole. As the positioning tube is released into the first positioning hole, the tube cavity of the positioning tube passes through the correction block and is quickly corrected into a round tube by the correction block. The notch of the positioning tube passes through the reducing part and is quickly corrected into a wide groove by the reducing part to ensure that the part of the positioning tube released to the front of the substrate is a round tube, and there are 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.

DETAILED DESCRIPTION

[0025] The above and other embodiments and advantages of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0026] In one embodiment, Figure 1-Figure 7 As 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. It is provided with mounting holes, or mounting holes are opened on site with an electric screwdriver when installing power components. The packaging device 2 plays an auxiliary role when installing power components 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. 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 by 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 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. 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 transmission-connected to the driving wheel 13. A second positioning hole 18 is opened on the second bracket 15, 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 outward from the reel 17, it becomes tubular through the secondary correction mechanism 20.

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

[0032] Further preferably, a horizontal portion 22 bent leftward is provided at the bottom end of the second bracket 15 , and the second positioning hole 18 is opened on the horizontal portion 22 of the second bracket 15 , and the second positioning hole 18 is close to between the driving wheel 11 and the reel 17 .

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

[0034] Further preferably, the motor 12 is fixed to the bottom of the carrier 3 via 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 base, and the motor 12 and the external pull switch 19 are electrically connected to the charging base.

[0036] Working principle and effect: When the power components are mounted on the substrate 1, the magnet 7 is used to adsorb the carrier 3 on the substrate 1, and the carrier 3 is used to press the entire packaging device 2 Figure 1The shown shape is installed on a corner of the substrate 1. At this time, the right side of the positioning plate 8 is tightly attached to the left side of the substrate 1. Under the positioning plate 8, the carrier 3 is horizontally placed in front of the substrate 1. The button on the external pull-out switch 19 (existing technology) is pressed 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 the belt transmission relationship. The driven wheel 14 drives the reel 17 to rotate, so that the positioning tube 6 wound on the reel 17 releases a length upward. When the positioning tube 6 releases a length upward, it is guided upward through the second positioning hole 18. When the positioning tube 6 releases a length upward, it is transported upward through the driving wheel 11. The top section of the positioning tube 6 is released 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 is released horizontally to the right along the front of the substrate 1. Considering that the power components are installed on the substrate 1 When the power component is installed on the substrate 1, the back side is often closely attached to the front side of the substrate 1, which affects the heat dissipation efficiency when power is turned on. Therefore, the positioning tube 6 is released to the front side of the substrate 1, which is equivalent to providing a forward-protruding support on the front side of the substrate 1. Before the power component (hereinafter referred to as the component for the convenience of description) is installed on the substrate 1, the back side of the component is placed on the positioning tube 6, and then the pins (or terminal wires) of the component are connected to the substrate 1 (generally, the component has at least two or two rows of pins above and below). When the component is installed on the substrate 1, the back side is supported by the positioning tube 6. Therefore, when the positioning tube 6 is retracted, it is equivalent to forming a space between the back side of the component and the front side of the substrate 1. The space formed between the installed component and the substrate 1 by the positioning tube 6 fully demonstrates that when the component is powered on, the back side has good air permeability and high heat dissipation efficiency, thereby improving their service life.

[0037] Continuing from the above, since the reel 17 can continue to release the positioning tube 6, the top section of the positioning tube 6 will also release a length to the right along the front of the substrate 1 to accommodate the installation of multiple components on the substrate 1. Through the above installation method, a breathable space can also be formed on the back of the multiple components after installation.

[0038] Continuing from the above, since the positioning tube 6 is provided with a slot 23 and the slot 23 is provided along the length direction of the positioning tube 6, the positioning tube 6 can radially shrink in the radial direction. In this way, when the positioning tube 6 passes through the second positioning hole 18 and the first positioning hole 9 in turn to release the length, it avoids being tightly fixed in the second positioning hole 18 and the first positioning hole 9, which causes obstacles 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 (compressed) when it is rolled onto the reel 17, thereby reducing the space, and when the positioning tube 6 is released outward, it returns to the tubular shape again. However, considering that the positioning tube 6 needs to release a longer length when it recovers from flat to tubular, a secondary correction mechanism 20 is set 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 round tube by the correction block 25. The notch 23 of the positioning tube 6 passes through the reducing portion 26 and is quickly corrected into a wide groove by the reducing portion 26 to ensure that the part of the positioning tube 6 released to the front of the substrate 1 is a round tube, and there are sufficient support conditions to support enough space between the back of the component and the front of the substrate 1 for the component to dissipate heat.

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

[0040] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described based on their actual installation and actual use, as well as the customary orientations of those skilled in the art. This is hereby explained.

[0041] The specific embodiments described above further illustrate the purpose of the present invention, technical solutions, and beneficial effects. It should be understood that the above description is merely a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. In particular, it should be noted that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
