Description

Technical Field

[0001] The present invention relates to the field of electronic component processing, and in particular to a punching device for electronic component processing. Background Art

[0002] During the circuit board drilling process, cover plates and backing plates play a crucial role. The cover plate is primarily placed on the upper surface of the copper-clad laminate being processed, directly contacting the drill bit and positioning the drill bit, dissipating heat, reducing burrs, and preventing pressure damage. The backing plate, placed on the lower surface of the copper-clad laminate being processed and in direct contact with the drilling equipment, protects the drill surface, prevents burrs at the exit, reduces drill bit temperature, and cleans the drill bit groove.

[0003] Specifically, the detailed functions of the cover plate and pad are as follows:

[0004] Cover Plate: Primarily made of aluminum, it serves as a drill bit positioning, dissipating heat, reducing burrs, and preventing pressure damage during the manufacturing process. It reduces the pressure on the drill bit when it contacts the material, preventing direct damage to the circuit board. It also helps the drill bit precisely align with the drilling location, ensuring drilling accuracy.

[0005] Pad: Primarily a composite board, it protects the drill rig surface, prevents burrs at the drill tip, reduces drill bit temperature, and cleans the drill bit groove. The pad material must have a certain degree of hardness and elasticity to prevent the drill bit from getting stuck or wearing out due to uneven material during drilling.

[0006] During the overall installation of the cover plate, circuit board, and pad, workers are required to always keep the cover plate, circuit board, and pad aligned as a whole, and after installation on the punching table, they need to be positioned with tape. The operation is cumbersome, and it is difficult to control the overall alignment of the cover plate, circuit board, and pad. Summary of the Invention

[0007] The purpose of the present invention is to solve the shortcomings of the prior art that during the installation of the cover plate, circuit board and pad as a whole, the staff needs to always keep the cover plate, circuit board and pad as a whole aligned, and after installation on the punching table, they need to be positioned with tape, which is cumbersome to operate and difficult to control the overall alignment of the cover plate, circuit board and pad. A punching device for electronic component processing is proposed.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is: a punching device for processing electronic components, comprising a punching table and a punching assembly; further comprising: a mounting groove, the mounting groove being provided on the top surface of the punching table; a flip table, the flip table being rotatably arranged in the mounting groove, and a positioning groove being provided on the top surface; a positioning assembly, the positioning assembly being arranged in the positioning groove, the positioning assembly comprising two first positioning plates and one second positioning plate; a first driving assembly, the first driving assembly being used to drive the two first positioning plates to clamp and position the two sides of the electronic component, and synchronously drive the second positioning plate to press against the end of the electronic component.

[0009] It should be noted that the punching assembly includes: a second motor, a drill bit is fixedly installed at the output end of the second motor; an adjustment platform, the adjustment platform is used to adjust the position of the second motor above the circuit board. Specifically, the adjustment platform includes a support platform, the support platform is fixedly installed on the top of the punching platform, a first sliding platform is provided on the surface of the support platform for horizontal sliding, and a first threaded drive component is connected between the first sliding platform and the support platform; a second sliding platform is provided on the surface of the first sliding platform for longitudinal sliding, a second threaded drive component is connected between the second sliding platform and the first sliding platform, a third sliding platform is provided on the surface of the second sliding platform for sliding, a third threaded drive component is connected between the third sliding platform and the second sliding platform, and the second motor is fixedly installed on the bottom surface of the third sliding platform;

[0010] It should be understood that when the cover plate, circuit board and backing plate need to be installed as a whole, the first threaded driving assembly is started, and the first threaded driving assembly thread-drives the first sliding table to move, thereby driving the second motor, the second sliding table and the third sliding table to move to a position away from above the flip table, thereby providing space for the flipping of the flip table; during processing, the first sliding table is moved to above the flip table by the first threaded driving assembly, and the second sliding table is driven to move by the second threaded driving assembly to adjust the longitudinal height of the second motor and the drill bit, and the third sliding table is driven to move by the third threaded driving assembly, thereby adjusting the movement of the second motor and the drill bit in the front-rear direction, thereby facilitating drilling holes at different positions on the top surface of the circuit board by adjusting the position of the drill bit;

[0011] After the cover plate and the pad have clamped the circuit board in the middle, the cover plate, the circuit board and the pad are placed as a whole into the positioning groove of the flipped flip table, and then the flip table is reset so that the staff can maintain a comfortable standing position to install the circuit board. After the flip table is reset, the first driving component drives the two first positioning plates to clamp and position the two sides of the electronic component, and the second positioning plate is synchronously driven to press the end of the electronic component, so that the two sides of the cover plate, the circuit board and the pad are clamped by the first positioning plate, and the rear end is pressed by the second positioning plate, so that the cover plate, the circuit board and the pad are positioned as a whole, and under the positioning action of the first positioning plate and the second positioning plate, the edges of the cover plate, the circuit board and the pad are aligned to prevent deviation during the punching process, which is beneficial to maintain the overall stability of the cover plate, the circuit board and the pad during the punching process of the punching component on the circuit board.

[0012] As an optional technical solution in the present invention, the first driving component includes:

[0013] A pushing frame, the pushing frame is slidably plugged into the top surface of the punching table, and both ends are fixedly connected with a push block, and the two push blocks are respectively fixedly connected to the two ends of the second positioning plate;

[0014] Two inclined surfaces, the two inclined surfaces are respectively provided at the ends of the two first positioning plates and are respectively in contact with the two push blocks;

[0015] A cylinder is fixedly installed between the pushing frame and the punching table.

[0016] Specifically, there are two cylinders, which are fixedly installed on both sides of the punching platform, and the ends of the piston rods are fixedly connected to the pushing frame.

[0017] It should be understood that after the flip table with the cover plate, circuit board and pad is placed and flipped back into the installation groove, the two cylinders are started synchronously, and the two cylinders pull the pushing frame synchronously. The pushing frame drives the two ejecting blocks and the second positioning plate to move, and contacts the two inclined surfaces until the second positioning plate presses the rear end of the cover plate, circuit board and pad together. The two first positioning plates are pushed to clamp the cover plate, circuit board and pad together, and press both sides of the cover plate, circuit board and pad together, so that the cover plate, circuit board and pad together are positioned while the edges of the cover plate, circuit board and pad together are aligned.

[0018] As a further preferred technical solution of the present invention, the first positioning plate includes a limiting end and a plug-in section, and the positioning assembly further includes:

[0019] Two pairs of elastic members, the two pairs of elastic members are respectively located between the two first positioning plates and the positioning grooves, and the two ends of the elastic members are respectively connected to the first positioning plates and the positioning grooves at corresponding positions;

[0020] Two third positioning plates, the two third positioning plates are respectively plugged into the plug-in sections of the two first positioning plates, and the surfaces of the two third positioning plates are fixedly connected with guide rails;

[0021] Two pairs of linkage pins, two linkage pins in the same pair are respectively inserted into the tracks at both ends of the guide rail on the same third positioning plate, and the two pairs of linkage pins are symmetrically fixedly connected to the top surfaces on both sides of the top surface of the turning table.

[0022] It should be understood that in the process of the two first positioning plates being driven by the driving assembly and approaching each other, the elastic member is pulled, and the guide rail moves toward the overall direction of the cover plate, circuit board and pad under the action of the linkage pin. When the limiting end of the first positioning plate is pressed against the overall side of the cover plate, circuit board and pad, the third positioning plate is driven by the guide rail to press the overall top surface of the cover plate, circuit board and pad, so that the stacking state of the cover plate, circuit board and pad is maintained, which is beneficial to make the cover plate, circuit board and pad stick together, and is beneficial to maintaining the clamping, support and protection of the cover plate and pad for the circuit board, and is beneficial to the pad and cover plate to absorb the heat generated by punching the circuit board in time and then dissipate the heat.

[0023] As a further preferred technical solution of the present invention, the second positioning plate has a ventilation cavity and an air outlet connected to the ventilation cavity, and a heat dissipation component is provided in the mounting groove, and the heat dissipation component includes:

[0024] A heat absorbing plate is arranged in the mounting groove, and the top surface of the heat absorbing plate contacts the bottom surface of the turning table, and a plurality of ventilation and heat dissipation pipes are provided through the heat absorbing plate;

[0025] A ventilation box is fixedly installed in the installation groove, and a ventilation valve is connected between the ventilation box and the ventilation cavity. The ventilation valve is used to cancel the connection between the ventilation box and the ventilation cavity when the second positioning plate moves to the positioning position, and the ventilation box is connected to the ends of multiple ventilation and heat dissipation pipes. After the second positioning plate moves away from the positioning position, the ventilation box is connected to the ventilation cavity, and the connection between the ventilation box and the ends of multiple ventilation and heat dissipation pipes is canceled.

[0026] It should be understood that during the drilling process, the ventilation box continuously injects air into the multiple ventilation and heat dissipation pipes. When the air flows through the ventilation and heat dissipation pipes, the heat absorbing plate absorbs the heat on the turning table, and the turning table absorbs the heat on the pad, and further absorbs and dissipates the heat through the ventilation and heat dissipation pipes, thereby achieving the heat dissipation effect;

[0027] It should be further explained that after the second positioning plate is away from the positioning station, the ventilation box is connected to the ventilation cavity, and the ventilation box is connected to the ends of multiple ventilation and heat dissipation pipes. The wind will blow above the heat absorbing plate through the air outlet to clean the top surface of the heat absorbing plate and avoid being blocked by debris falling on the heat absorbing plate when the flip table is flipped and reset.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] In the present invention, after the cover plate and the backing plate sandwich the circuit board, the cover plate, the circuit board and the backing plate are placed in the positioning groove of the flip table, and then the flip table is reset, so that the worker can maintain a comfortable standing position to install the circuit board.

[0030] After the flip table is reset, the driving assembly drives the two first positioning plates to clamp and position the two sides of the electronic component, and the second positioning plate is synchronously driven to press the end of the electronic component, so that the cover plate, circuit board and pad are positioned as a whole. At the same time, the edges of the cover plate, circuit board and pad are aligned to prevent displacement during the punching process, which is beneficial to maintain the overall stability of the cover plate, circuit board and pad during the punching process of the circuit board by the punching assembly. The entire positioning process is automatically realized, and the alignment adjustment is automatically realized, which is convenient and fast, and reduces the difficulty of keeping the circuit board aligned with the cover plate and pad.

[0031] Driven by the guide rail, the third positioning plate presses the overall top surface of the cover plate, circuit board and pad, so that the stacking state of the cover plate, circuit board and pad is maintained, which is beneficial to make the cover plate, circuit board and pad stick together, and is beneficial to maintaining the clamping, supporting and protecting effect of the cover plate and pad on the circuit board, and is beneficial to the pad and cover plate to absorb the heat generated by punching the circuit board in time and then dissipate the heat.

[0032] During the drilling process, the ventilation box continuously injects air into multiple ventilation and heat dissipation pipes. As the air flows through the ventilation and heat dissipation pipes, the heat absorbing plate absorbs the heat on the turning table. The turning table absorbs the heat on the pad and further absorbs and dissipates the heat through the ventilation and heat dissipation pipes, thereby achieving the heat dissipation effect.

[0033] After the second positioning plate is away from the positioning station, the ventilation box is connected to the ventilation cavity, and the ventilation box is connected to the ends of multiple ventilation and heat dissipation pipes. The wind will blow above the heat absorbing plate through the air blowing port to clean the top surface of the heat absorbing plate and avoid being blocked by debris falling on the heat absorbing plate when the turning table is turned over and reset.

DETAILED DESCRIPTION

[0046] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0047] In order to better understand the present invention, the following explanations are given:

[0048] like Figure 11 As shown, the electronic component is specifically a circuit board 24. Before drilling, the top of the circuit board 24 will be covered with a cover plate 23 and the bottom will be padded with a pad 25. The requirements for the cover plate 23 and the pad 25 are mainly as follows: they have a certain elasticity, and they will deform immediately when the drill bit 21 makes contact with the drill, so that the drill bit 21 is accurately aligned with the position to be drilled, ensuring the accuracy of the drilling position; they have a certain surface hardness to prevent burrs from forming on the upper and lower surfaces of the material during drilling, but they cannot be too hard to avoid serious wear of the drill bit 21; the resin component of the material itself is not easy to form drill stains; the thermal conductivity is large, which can quickly take away the heat generated during drilling and reduce the temperature of the drill needle; and they must have a certain rigidity to prevent the plate from shaking when the drill bit 21 is lifted.

[0049] like Figures 1 to 10 The punching device for processing electronic components shown includes a punching table 1 and a punching assembly;

[0050] It should be noted that the punching assembly includes: a second motor 20, with a drill bit 21 fixedly mounted on the output end of the second motor 20; an adjustment platform 22, which is used to adjust the position of the second motor 20 above the circuit board 24. Specifically, the adjustment platform 22 includes a support platform 2201, which is fixedly mounted on the top of the punching platform 1, with a first sliding platform 2202 sliding horizontally on the surface of the support platform 2201, and a first thread drive assembly 2203 connected between the first sliding platform 2202 and the support platform 2201; a second sliding platform 2204 sliding longitudinally on the surface of the first sliding platform 2202, with a second thread drive assembly 2205 connected between the second sliding platform 2204 and the first sliding platform 2202; a third sliding platform 2206 sliding on the surface of the second sliding platform 2204 slidingly, with a third thread drive assembly 2207 connected between the third sliding platform 2206 and the second sliding platform 2204, and the second motor 20 fixedly mounted on the bottom surface of the third sliding platform 2206;

[0051] It should be understood that when the cover plate 23, the circuit board 24 and the pad 25 need to be installed as a whole, the first threaded drive assembly 2203 is started, and the first threaded drive assembly 2203 threadably drives the first sliding table 2202 to move, driving the second motor 20, the second sliding table 2204 and the third sliding table 2206 to move to a position away from the top of the flip table 2, thereby providing space for the flipping of the flip table 2; during processing, the first sliding table 2202 is moved to the top of the flip table 2 by the first threaded drive assembly 2203, and the second sliding table 2204 is driven to move by the second threaded drive assembly 2205 to adjust the longitudinal height of the second motor 20 and the drill bit 21, and the third sliding table 2206 is driven to move by the third threaded drive assembly 2207, thereby adjusting the front-rear movement of the second motor 20 and the drill bit 21, which is beneficial for drilling holes at different positions on the top surface of the circuit board 24 by adjusting the position of the drill bit 21;

[0052] The punching device for electronic component processing also includes:

[0053] The mounting groove 101 is provided on the top surface of the punching table 1;

[0054] The turning table 2 is rotatably arranged in the installation groove 101, and a positioning groove 201 is opened on the top surface;

[0055] The positioning assembly is arranged in the positioning groove 201 and includes two first positioning plates 3 and a second positioning plate 4;

[0056] The first driving assembly is used to drive the two first positioning plates 3 to clamp and position the two sides of the electronic component, and synchronously drive the second positioning plate 4 to press the end of the electronic component.

[0057] The first positioning plate 3 and the second positioning plate 4 are used to hold the cover 23, circuit board 24 and pad 25 in place.

[0058] As an optional embodiment of the present invention, the first drive assembly includes:

[0059] The pushing frame 5 is slidably inserted into the top surface of the punching table 1, and the two ends are fixedly connected with the push blocks 6, and the two push blocks 6 are fixedly connected to the two ends of the second positioning plate 4 respectively;

[0060] Two inclined surfaces 601 are respectively provided at the ends of the two first positioning plates 3 and are in contact with the two push blocks 6 respectively;

[0061] Cylinder 7, cylinder 7 is fixedly installed between the pushing frame 5 and the punching table 1.

[0062] Specifically, there are two cylinders 7 , which are fixedly installed on both sides of the punching table 1 , and the ends of the piston rods are fixedly connected to the pushing frame 5 .

[0063] It should be understood that after the flip table 2 with the cover plate 23, circuit board 24 and pad 25 as a whole is flipped and reset in the installation groove 101, the two cylinders 7 are started synchronously, and the two cylinders 7 pull the pushing frame 5 synchronously. In the process of the pushing frame 5 driving the two ejecting blocks 6 and the second positioning plate 4 to move, they contact the two inclined surfaces 601 until the second positioning plate 4 presses the rear end of the cover plate 23, circuit board 24 and pad 25 as a whole. The two first positioning plates 3 are pushed to clamp the cover plate 23, circuit board 24 and pad 25 as a whole, and press the two sides of the cover plate 23, circuit board 24 and pad 25 as a whole, so that the cover plate 23, circuit board 24 and pad 25 as a whole are positioned, and the edges of the cover plate 23, circuit board 24 and pad 25 are aligned.

[0064] As a further preferred embodiment of the present invention, the first positioning plate 3 includes a limiting end and an inserting section, and the positioning assembly further includes:

[0065] Two pairs of elastic members 8, the two pairs of elastic members 8 are respectively located between the two first positioning plates 3 and the positioning grooves 201, and the two ends of the elastic members 8 are respectively connected to the first positioning plates 3 and the positioning grooves 201 at corresponding positions;

[0066] Two third positioning plates 9, which are respectively plugged into the plug-in sections of the two first positioning plates 3, and both surfaces are fixedly connected with guide rails 10;

[0067] Two pairs of linkage pins 11 are respectively inserted into the tracks at both ends of the guide rail 10 on the same third positioning plate 9, and the two pairs of linkage pins 11 are symmetrically fixedly connected to the top surfaces on both sides of the top surface of the turning table 2.

[0068] It should be understood that in the process of the two first positioning plates 3 being driven by the driving assembly and approaching each other, the elastic member 8 is pulled, and the guide rail 10 moves toward the overall direction of the cover plate 23, circuit board 24 and pad 25 under the action of the linkage pin 11. When the limiting end of the first positioning plate 3 is pressed against the overall side of the cover plate 23, circuit board 24 and pad 25, the third positioning plate 9 is driven by the guide rail 10 to press the overall top surface of the cover plate 23, circuit board 24 and pad 25, so that the stacking state of the cover plate 23, circuit board 24 and pad 25 is maintained, which is beneficial to making the cover plate 23, circuit board 24 and pad 25 stick to each other, and is beneficial to maintaining the clamping, support and protection of the cover plate 23 and pad 25 for the circuit board 24, and is beneficial to the pad 25 and cover plate 23 to absorb the heat generated by the punching of the circuit board 24 in time and then dissipate the heat.

[0069] As a further preferred embodiment of the present invention, the second positioning plate 4 has a ventilation cavity 401 and an air outlet 402 connected to the ventilation cavity 401, and a heat dissipation component is provided in the mounting groove 101, and the heat dissipation component includes:

[0070] The heat absorbing plate 12 is arranged in the mounting groove 101, and the top surface of the heat absorbing plate 12 contacts the bottom surface of the turning table 2, and a plurality of ventilation and heat dissipation pipes 13 are provided through the heat absorbing plate 12;

[0071] The ventilation box 14 is fixedly installed in the installation groove 101, and a ventilation valve 15 is connected between the ventilation box 14 and the ventilation cavity 401. The ventilation valve 15 is used to cancel the connection between the ventilation box 14 and the ventilation cavity 401 when the second positioning plate 4 moves to the positioning position, and the ventilation box 14 is connected to the ends of multiple ventilation and heat dissipation pipes 13. After the second positioning plate 4 is away from the positioning position, the ventilation box 14 is connected to the ventilation cavity 401, and the connection between the ventilation box 14 and the ends of multiple ventilation and heat dissipation pipes 13 is canceled.

[0072] It should be understood that during the drilling process, the ventilation box 14 continuously injects air into the multiple ventilation and heat dissipation pipes 13. When the air flows through the ventilation and heat dissipation pipes 13, the heat absorbing plate 12 absorbs the heat on the turning table 2, and the turning table 2 absorbs the heat on the pad 25. The heat is further absorbed and dissipated through the ventilation and heat dissipation pipes 13, thereby achieving the heat dissipation effect.

[0073] It should be further explained that after the second positioning plate 4 is away from the positioning position, the ventilation box 14 is connected to the ventilation cavity 401, and the ventilation box 14 is connected to the ends of multiple ventilation and heat dissipation pipes 13. The wind will be blown above the heat absorbing plate 12 through the blowing port 402 to clean the top surface of the heat absorbing plate 12, so as to avoid being blocked by debris falling on the heat absorbing plate 12 when the turning table 2 is turned over and reset.

[0074] Specifically, the heat dissipation component also includes:

[0075] The fan 16 is connected to the ventilation box 14 through a pipeline.

[0076] Specifically, the fan 16 is fixedly installed on the surface of the drilling platform 1 , and the pipeline passes through the drilling platform 1 .

[0077] It should be understood that by providing the fan 16 , air is injected into the ventilation box 14 , and external air is injected into the ventilation box 14 , providing the ventilation box 14 with a continuous supply of air.

[0078] As a further preferred embodiment of the present invention, a discharge port 17 is provided at the end of the heat absorbing plate 12 , and the bottom surface of the discharge port 17 is inclined.

[0079] It should be understood that by providing the discharge port 17 , the impurities on the top surface of the heat absorbing plate 12 can be blown away and cleaned to the tail end of the heat absorbing plate 12 for drainage and discharge through the discharge port 17 .

[0080] As an optional embodiment of the present invention, a second drive assembly is further installed on the punching table 1, and the second drive assembly is used to drive the flip table 2 to flip. The second drive assembly includes:

[0081] Two support shafts 18, the two support shafts 18 are symmetrically fixedly connected to the ends of the turning table 2, and are both rotatably connected in the mounting groove 101;

[0082] The first motor 19 is fixedly mounted on the punching table 1 , and an output end of the first motor 19 is fixedly connected to one of the support shafts 18 .

[0083] It should be understood that when the flip table 2 needs to be flipped and adjusted, the first motor 19 is started, the first motor 19 drives the support shaft 18 to rotate, and the support shaft 18 synchronously drives the flip table 2 to rotate, thereby realizing the flip adjustment of the flip table 2, and when it is flipped to an angle that is convenient for placing the cover plate 23, the circuit board 24, and the pad 25 as a whole, the first motor 19 is turned off. The first motor 19 is a self-locking motor, which can maintain the flip state of the flip table 2, making it convenient to install the cover plate 23, the circuit board 24, and the pad 25 as a whole.

[0084] Specifically, the ventilation valve 15 includes:

[0085] Sealing tube 1501, sealing tube 1501 is fixedly connected to the inner wall of ventilation box 14;

[0086] The ventilation pipe 1502 is slidably inserted into the sealing tube 1501 and has a ventilation hole 1503 on its surface. The ventilation hole 1503 is located in the sealing tube 1501. The ventilation pipe 1502 passes through the ventilation box 14 and is fixedly connected to the ventilation cavity 401.

[0087] The sealing plate 1504 is slidably arranged on the inner bottom surface of the ventilation box 14, and the top end is fixedly connected to the end of the ventilation pipe 1502 through a bracket.

[0088] It should be understood that when the second positioning plate 4 moves to the positioning position, the vent hole 1503 of the vent pipe 1502 is located in the sealing tube 1501, the connection point between the vent pipe 1502 and the ventilation box 14 is blocked, and the sealing plate 1504 is away from the connection point between the ventilation and heat dissipation pipe 13 and the ventilation box 14. The ventilation and heat dissipation pipe 13 and the ventilation box 14 remain connected, and the connection between the ventilation box 14 and the ventilation cavity 401 is cancelled, so that the heat absorption plate 12 is continuously cooled, and the air flow can only circulate through the ventilation and heat dissipation pipe 13. After the workstation is in the working position, the vent hole 1503 of the vent pipe 1502 is moved out of the sealing tube 1501, and the connection between the ventilation box 14 and the ventilation cavity 401 is blocked and sealed by the bracket, and the connection between the ventilation box 14 and the multiple ventilation and heat dissipation pipes 13 is cancelled, so that the wind can only enter the ventilation cavity 401 through the vent pipe 1502, and be blown to the top surface of the heat absorbing plate 12 through the air outlet for cleaning, which helps to prevent fallen debris from staying on the top surface of the heat absorbing plate 12.

[0089] Specifically, the elastic member 8 includes:

[0090] Support pin 801, the support pin 801 is fixedly connected to the side surface of the first positioning plate 3, and the support pin 801 is slidably inserted into the inner wall of the positioning groove 201;

[0091] The support spring 802 is sleeved on the surface of the support pin 801 , and its two ends are fixedly connected to the first positioning plate 3 and the inner wall of the positioning groove 201 respectively.

[0092] The support pin 801 and the support spring 802 are provided to elastically support the first positioning plate 3 .

[0093] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
