Description

Technical Field

[0001] This invention belongs to the field of rotor glue injection technology, and specifically relates to a glue injection mechanism for motor rotor processing. Background Technology

[0002] Due to its comprehensive advantages such as high efficiency, high power density, and low noise, permanent magnet synchronous motors (PMSMs) have become the mainstream drive motor type for new energy passenger vehicles. During the production of PMSM rotors, after the rotor and bearings are assembled, an anaerobic adhesive is applied to the outer surface of the rotor bearing using an adhesive injection device. This allows the anaerobic adhesive to completely fill the microscopic gaps between the bearing and bearing housing mating surfaces during assembly with the PMSM housing, eliminating fretting wear caused by vibration, ensuring long-term stability and accuracy of the bearing position, providing sealing and corrosion protection, and facilitating future maintenance and disassembly.

[0003] However, existing glue injection equipment typically injects a layer of anaerobic adhesive directly onto the outer ring of the bearing. During the production of permanent magnet synchronous motor rotors, oil and other impurities adhere to the outer surface of the bearing. The presence of oil will affect the performance of the anaerobic adhesive, preventing it from effectively filling the mating surfaces between the bearing and the bearing housing. This results in fretting wear between the bearing and the bearing housing during the operation of the permanent magnet synchronous motor, thus shortening the service life of the motor. Based on this, a glue injection mechanism for motor rotor processing is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a glue injection mechanism for machining motor rotors in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

The oil removal assembly includes an electric telescopic rod fixedly connected to the glue-applying assembly. A lifting block is fixedly connected to the top of the electric telescopic rod. Two wiping blocks are installed inside the lifting block. A pump body is fixedly connected to one end of the lifting block. A liquid-drawing pipe is fixedly connected to the liquid-drawing end of the pump body. A liquid-draining pipe is fixedly connected to the liquid-draining end of the pump body. A groove adapted to the liquid-draining pipe is opened at the bottom of one of the wiping blocks. A spray chamber is fixedly connected inside the lifting block. The liquid-draining pipe is fixedly connected to the spray chamber. A spray hole is opened at the top of the spray chamber.

[0007] As a further optimization of the present invention, the glue injection assembly includes an electric lead screw, a slider is threadedly connected to the electric lead screw, a mounting base is fixedly connected to the slider, a glue cylinder is mounted on the mounting base, a connecting frame is fixedly connected to the back of the mounting base, and a connecting plate is slidably connected inside the connecting frame.

[0008] As a further optimization of the present invention, the spray chamber is located between the two wiping blocks, the upper surface of the spray chamber is lower than the upper surface of the two wiping blocks, and a through groove is provided on the connecting plate for the liquid extraction pipe to pass through.

[0009] As a further optimization of the present invention, the drying assembly includes a piston cylinder fixedly connected to the top of the connecting plate, a piston plate slidably connected inside the piston cylinder, the piston plate being fixedly connected to the bottom of the lifting block, an air extraction pipe being fixedly connected to one side of the piston cylinder, a dustproof net being fixedly connected to the air inlet end of the air extraction pipe, and an air blowing pipe being fixedly connected to one side of the piston cylinder located on the air extraction pipe, with multiple air blowing holes provided on the air blowing pipe, the multiple air blowing holes being positioned directly opposite the bearings mounted on the rotor.

[0010] As a further optimization of the present invention, the top of the rubber tube is fixedly connected to a second air pipe by a thread, a through groove is provided on the connecting plate, the through groove is slidably connected to the connecting frame, a limit rod is fixedly connected to the top of the control seat, and the connecting plate is slidably connected to the limit rod.

[0011] As a further optimization of the present invention, the drive assembly includes an electric slide fixedly connected to the top of the control seat, a slide block is mounted on the electric slide block, the slide block is slidably connected to the top of the control seat, a drive motor is fixedly connected to the slide block, a pneumatic block is fixedly connected to the output end of the drive motor, and a pneumatic clamp is fixedly connected to the end of the pneumatic block.

[0012] As a further optimization of the present invention, the lifting assembly includes a fixed plate fixedly connected to the positioning block, a lifting cylinder fixedly connected to the fixed plate, a lifting plate fixedly connected to the output end of the lifting cylinder, a limit groove formed on the fixed plate, and the lifting plate slidably connected to the limit groove.

[0013] As a further optimization of the present invention, the electric lead screw is installed inside the lifting plate, and the slider is slidably connected to the inner surface of the lifting plate, and the two are in close contact.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention, through the setting of the degreasing component, sprays the degreasing agent onto the outer surface of the bearing through the spray nozzle. Simultaneously, due to the rotation of the rotor, the degreasing agent is evenly sprayed onto the outer surface of the bearing. At the same time, the wiping block wipes the outer surface of the bearing, allowing the degreasing agent to better dissolve oil stains, ensuring the cleanliness of the bearing outer ring. This prevents the presence of oil stains from hindering the adhesion of the anaerobic adhesive to the outer surface of the bearing outer ring, reduces the probability of oil stains affecting the physical properties of the anaerobic adhesive, and ensures the viscosity of the anaerobic adhesive. This allows the anaerobic adhesive to effectively fill the mating surface between the bearing and the bearing housing, ensuring the quality of the produced motor.

[0016] 2. This invention, through the setting of the electric slide, ensures that the anaerobic adhesive injected by the glue cylinder onto the outer surface of the bearing is distributed in an "S" shape. This "S"-shaped distribution of the anaerobic adhesive ensures that the anaerobic adhesive covers the bearing in a 360° circumferential direction. When the bearing is pressed in, the anaerobic adhesive is evenly squeezed towards the "crests" and "troughs" of the "S" shape. In addition, the anaerobic adhesive can also be squeezed in a direction perpendicular to the connection direction of the "crests" and "troughs," which can better fill the gaps between the bearing and the bearing housing mating surfaces, greatly reducing the risk of local missing adhesive. This forms a complete barrier between the outer ring of the bearing and the bearing housing, with better sealing and more consistent locking force. It ensures the formation of a complete, uniform, and bubble-free adhesive film, thereby providing the best anti-loosening, anti-fretting corrosion, and sealing performance, ultimately extending the service life of the motor and bearing.

[0017] 3. By using an air-blowing component, the present invention dries the residual degreasing agent on the outer surface of the bearing outer ring during the downward movement of the lifting block. This ensures the dryness of the bearing outer ring and prevents residual degreasing agent from affecting the adhesion between the anaerobic adhesive and the bearing outer ring. This ensures that the anaerobic adhesive can be firmly bonded to the outer surface of the bearing outer ring, thereby ensuring the quality of the motor produced subsequently.

[0018] 4. By using the connecting frame, through groove, and connecting plate in combination, the present invention allows the connecting plate to slide inward or outward through the connecting frame and through groove when the mounting base moves, thereby enabling the oil removal component to be positioned directly below the bearing. This achieves synchronous adjustment of the position of the oil removal component and the oil injection position, ensuring that the oil removal component can be positioned directly below rotor bearings of different sizes. This expands the application range of the mechanism and facilitates the gluing operation for rotor bearings of different sizes. Attached Figure Description

[0029] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Example: Figure 1 , Figure 2 and Figure 3As shown, a glue-injection mechanism for motor rotor processing includes a control base 1, a control module installed inside the control base 1, and the control module for controlling the operation of the glue-injection mechanism. A support plate 2 is fixedly connected to the top of the control base 1, and a support block 3 is fixedly connected to the top of the control base 1. A ball bearing 4 is rolled on the top of the support block 3. The ball bearing 4 can roll in all directions, which facilitates the rotation of the rotor and its left and right movement during rotation. A support column 5 is fixedly connected to the top of the control base 1. A locking block 6 is fixedly connected to the outer surface of the support column 5 by bolts. A support rod 7 is fixedly connected to the locking block 6 by bolts. A positioning block 8 is fixedly connected to the support rod 7 by bolts. A useful... The drive assembly 9, which clamps and rotates the rotor, includes an electric slide 91 fixedly connected to the top of the control base 1. A slide block 92 is mounted on the electric slide 91 and is slidably connected to the top of the control base 1. A drive motor 93 is fixedly connected to the slide block 92. A pneumatic block 94 is fixedly connected to the output end of the drive motor 93. A pneumatic clamping plate 95 is fixedly connected to the end of the pneumatic block 94. An annular air chamber (the annular air chamber is prior art) is fixedly connected to the outer surface of the drive motor 93. A first air pipe 96 is fixedly connected to the outer surface of the annular air chamber. The pneumatic block 94 is rotatably connected to the air chamber in a sealed manner, and the two are internally connected. The first air pipe 96 is fixedly connected to an external air pump (the air pump is prior art and is not shown in the figure, so it will not be described in detail).

[0031] In use, the permanent magnet synchronous motor rotor equipped with bearings is placed on top of the support plate 2 and support block 3, so that the permanent magnet synchronous motor rotor is located on the outer surface of the ball 4. Then the rotor is pushed into the pneumatic chuck 95, and the pneumatic chuck 95 clamps and fixes the permanent magnet synchronous motor rotor by injecting air into the first air pipe 96.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the lifting assembly 10 is equipped with a glue injection assembly 11 for injecting glue onto the outer surface of the bearing mounted on the rotor. The glue injection assembly 11 includes an electric lead screw 111, a slider 112 connected to the electric lead screw 111 by a thread, a mounting base 113 fixedly connected to the slider 112, a glue cylinder 114 installed on the mounting base 113, the glue cylinder 114 being filled with anaerobic glue, a second air pipe 115 fixedly connected to the top of the glue cylinder 114 by a thread, the second air pipe 115 being fixedly connected to an air pump (the air pump is prior art and is not shown in the figure, so it will not be described in detail), a connecting frame 116 fixedly connected to the back of the mounting base 113, a connecting plate 117 slidably connected inside the connecting frame 116, a through groove 118 opened on the connecting plate 117, the through groove 118 being slidably connected to the connecting frame 116, a limit rod 119 fixedly connected to the top of the control base 1, and the connecting plate 117 being slidably connected to the limit rod 119.

[0033] After the rotor is installed, start the electric lead screw 111 to make the slider 112 slide inward or outward, thereby adjusting the distance between the mounting seats 113 so that the distance between the rubber tubes 114 is equal to the distance between the bearings mounted on the rotor. At this time, start the electric slide table 91 to make the slide 92 slide on the top of the control seat 1 until the rubber discharge end of the rubber tube 114 is directly opposite the bearing.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a lifting assembly 10 is fixedly connected to the positioning block 8. The lifting assembly 10 includes a fixed plate 101 fixedly connected to the positioning block 8, a lifting cylinder 102 fixedly connected to the fixed plate 101, a lifting plate 103 fixedly connected to the output end of the lifting cylinder 102, an electric lead screw 111 installed inside the lifting plate 103, a slider 112 slidably connected to the inner surface of the lifting plate 103 and the two are in contact, a limit groove 104 is provided on the fixed plate 101, and the lifting plate 103 is slidably connected to the limit groove 104.

[0035] After the discharge end of the glue cartridge 114 is aligned with the bearing, the lifting cylinder 102 can be activated to slide the lifting plate 103 downwards, thereby moving the discharge end of the glue cartridge 114 toward the bearing of the rotor. Once the appropriate height is reached, the lifting cylinder 102 is closed. At this time, the air pump injects air into the glue cartridge 114 through the second air pipe 115, causing the discharge end of the glue cartridge 114 to inject glue onto the outer surface of the bearing. Simultaneously, the drive motor 93 is activated, causing the pneumatic block 94 to drive the rotor to rotate through the pneumatic clamp 95, allowing the glue cartridge 114 to inject glue onto the outer surface of the bearing. During the glue injection process, the electric slide table 91 is activated, causing the slide block 92 to move back and forth left and right, thereby causing the anaerobic glue injected by the glue cartridge 114 onto the outer surface of the bearing to be distributed in an "S" shape on the outer surface of the bearing. The anaerobic adhesive, distributed in an "S" shape, ensures that the anaerobic adhesive covers the bearing's 360° circumference. When the bearing is pressed in, the anaerobic adhesive is evenly squeezed towards the "crests" and "troughs" of the "S" shape. In addition, the anaerobic adhesive can also be squeezed perpendicular to the connection direction of the "crests" and "troughs," which can better fill the gaps between the bearing and the bearing housing's entire mating surface, greatly reducing the risk of localized adhesive shortage. This forms a complete barrier between the bearing outer ring and the bearing housing, with better sealing and more consistent locking force, ensuring the formation of a complete, uniform, and bubble-free adhesive film. This provides superior anti-loosening, anti-fretting corrosion, and sealing performance, ultimately extending the service life of the permanent magnet synchronous motor and bearing.

[0036] like Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, an oil removal assembly 12 and a drying assembly 13 are fixedly connected to the top of the connecting plate 117. The oil removal assembly 12 includes an electric telescopic rod 121 fixedly connected to the top of the connecting plate 117. A lifting block 122 is fixedly connected to the top of the electric telescopic rod 121. Two wiping blocks 123 (which can be sponges or non-woven fabrics, etc.) are installed inside the lifting block 122. After a period of use, the wiping blocks 123 can be directly removed from the lifting block 122 for replacement. A pump body 124 is fixedly connected to one end of the lifting block 122. A liquid suction pipe 125 is fixedly connected to the liquid suction end of the pump body 124. The liquid suction pipe 125 is fixedly connected to the oil removal agent tank (the oil removal agent tank is prior art and is not shown in the figure). (Details omitted) The degreasing agent can be a multi-functional cleaner or an electronic contact cleaner, etc. A through groove is provided on the connecting plate 117 for the liquid suction pipe 125 to pass through. The discharge end of the pump body 124 is fixedly connected to the discharge pipe 126. The bottom of one of the wiping blocks 123 is provided with a groove 1231 that is adapted to the discharge pipe 126. A spray chamber 127 is fixedly connected inside the lifting block 122. The spray chamber 127 is located between the two wiping blocks 123. The upper end surface of the spray chamber 127 is lower than the upper end surface of the two wiping blocks 123. The discharge pipe 126 is fixedly connected to the spray chamber 127. A spray hole 128 is provided on the top of the spray chamber 127. The spray hole 128 is set directly opposite the bearing on the rotor.

[0037] After the rotor is installed but before adhesive is applied, when the mounting base 113 moves, it will cause the connecting plate 117 to slide inward or outward through the connecting frame 116 and the through slot 118. This allows the oil removal assembly 12 to be positioned directly below the bearing, achieving synchronous adjustment of the position of the oil removal assembly 12 and the oiling position. This ensures that the oil removal assembly 12 can be positioned directly below rotor bearings of different sizes, expanding the application range of the mechanism and facilitating adhesive application to rotor bearings of different sizes. Then, the electric telescopic rod 121 is activated, causing the lifting block 122 to move upward until both wiping blocks 123 are in contact with the bearing. The drive motor 93 is then activated, causing the rotor to rotate. Simultaneously, the pump body 124 is activated, causing the pump body 124 to pump liquid through the suction pipe 1... 25. Extract the degreasing agent from the degreasing agent tank and discharge it into the spray chamber 127 through the drain pipe 126. Finally, spray it onto the outer surface of the bearing through the spray hole 128. Due to the rotation of the rotor, the degreasing agent can be evenly sprayed onto the outer surface of the bearing. At the same time, the wiping block 123 will wipe the outer surface of the bearing, so that the degreasing agent can better dissolve the oil stains, ensuring the cleanliness of the bearing outer ring. This avoids the presence of oil stains, which may prevent the anaerobic adhesive from bonding well to the outer surface of the bearing outer ring. It also reduces the probability that oil stains will affect the physical properties of the anaerobic adhesive, ensuring the viscosity of the anaerobic adhesive. This allows the anaerobic adhesive to effectively fill the mating surface between the bearing and the bearing housing, ensuring the quality of the permanent magnet synchronous motor produced.

[0038] In addition, to improve the degreasing efficiency, the electric slide table 91 can be activated during the degreasing process to make the bearing slide left and right on the outer surface of the wiping block 123, thereby increasing the friction between the wiping block 123 and the bearing, so that the degreasing agent can better remove the oil stains on the outer surface of the bearing.

[0039] After thoroughly degreasing the outer ring of the bearing, turn off the pump body 124, start the electric telescopic rod 121 to reset the lifting block 122, and then proceed with the subsequent glue injection operation.

[0040] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the drying assembly 13 includes a piston cylinder 131 fixedly connected to the top of the connecting plate 117. A piston plate 132 is slidably connected inside the piston cylinder 131. The piston plate 132 is fixedly connected to the bottom of the lifting block 122. A suction pipe 133 is fixedly connected to one side of the piston cylinder 131. A one-way valve is installed inside the suction pipe 133, so that the piston cylinder 131 can only draw in external gas through the suction pipe 133. A dustproof net is fixedly connected to the air inlet end of the suction pipe 133. The dustproof net is used to block particulate impurities in the air and ensure the cleanliness of the air entering the piston cylinder 131. A blowing pipe 134 is fixedly connected to one side of the piston cylinder 131 located in the suction pipe 133. A one-way valve is installed inside the blowing pipe 134, so that the gas in the piston cylinder 131 can only be discharged through the blowing pipe 134. Multiple blowing holes 135 are opened on the blowing pipe 134, and the multiple blowing holes 135 are set directly opposite the bearings mounted on the rotor.

[0041] When the lifting block 122 moves upward, it pulls the piston plate 132 to slide upward along the inner surface of the piston cylinder 131, allowing the piston cylinder 131 to draw in outside air through the suction pipe 133. When the lifting block 122 moves downward, the piston plate 132 slides downward along the inner surface of the piston cylinder 131, forcing the air in the piston cylinder 131 into the blowing pipe 134, which then blows the air through the blowing hole 135 onto the outer surface of the bearing outer ring. At this time, the bearing outer ring is still rotating, so the degreasing agent remaining on the outer surface of the bearing outer ring can be dried during the downward movement of the lifting block 122, ensuring the dryness of the bearing outer ring and preventing residual degreasing agent from affecting the subsequent adhesion between the anaerobic adhesive and the bearing outer ring. This ensures that the anaerobic adhesive can be firmly bonded to the outer surface of the bearing outer ring, thereby ensuring the quality of the permanent magnet synchronous motor produced later.

[0042] A glue injection mechanism for machining motor rotors, in use, places the permanent magnet synchronous motor rotor equipped with bearings on top of the support plate 2 and support block 3, so that the permanent magnet synchronous motor rotor is located on the outer surface of the ball 4, and then pushes the rotor into the pneumatic chuck 95. By injecting air into the first air pipe 96, the pneumatic chuck 95 clamps and fixes the permanent magnet synchronous motor rotor.

[0043] After the rotor is installed, the electric screw 111 is activated to make the slider 112 slide inward or outward, thereby adjusting the distance between the mounting seats 113 so that the distance between the glue cylinders 114 is equal to the distance between the bearings mounted on the rotor. At this time, the electric slide table 91 is activated to make the slide seat 92 slide on the top of the control seat 1 until the glue discharge end of the glue cylinder 114 is directly opposite the bearing. At the same time, when the mounting seat 113 moves, the connecting plate 117 will be driven to slide inward or outward through the connecting frame 116 and the through groove 118, so that the oil removal component 12 can be positioned directly below the bearing. This realizes the synchronous adjustment of the position of the oil removal component 12 and the oil injection position, ensuring that the oil removal component 12 can be positioned directly below rotor bearings of different sizes, expanding the application range of the mechanism and facilitating glue injection operations for rotor bearings of different sizes.

[0044] The electric telescopic rod 121 is activated, causing the lifting block 122 to move upward until both wiping blocks 123 are in contact with the bearing. Then, the drive motor 93 is activated, causing the rotor to rotate. Simultaneously, the pump body 124 is activated, drawing degreasing agent from the degreasing agent tank through the suction pipe 125 and discharging it into the spray chamber 127 through the drain pipe 126. Finally, the degreasing agent is sprayed onto the outer surface of the bearing through the spray hole 128. Due to the rotation of the rotor, the degreasing agent is evenly sprayed onto the outer surface of the bearing. At the same time, the wiping blocks 123 wipe the outer surface of the bearing, allowing the degreasing agent to better dissolve the oil stains, ensuring the cleanliness of the bearing outer ring and preventing the presence of oil stains from hindering the effective application of the anaerobic adhesive. The adhesive adheres to the outer surface of the bearing outer ring, avoiding the probability of oil contamination affecting the physical properties of the anaerobic adhesive and ensuring the viscosity of the anaerobic adhesive. This allows the anaerobic adhesive to effectively fill the mating surfaces between the bearing and the bearing housing, ensuring the quality of the produced permanent magnet synchronous motor. In addition, to improve the degreasing efficiency, the electric slide table 91 can be activated during the degreasing process to make the bearing slide left and right on the outer surface of the wiping block 123, increasing the friction between the wiping block 123 and the bearing, so that the degreasing agent can better remove the oil contaminants from the outer surface of the bearing. Furthermore, when the lifting block 122 moves upward, it will pull the piston plate 132 to slide upward along the inner surface of the piston cylinder 131, allowing the piston cylinder 131 to draw in outside air through the air extraction pipe 133.

[0045] After thoroughly degreasing the outer ring of the bearing, the pump body 124 is turned off, and the electric telescopic rod 121 is activated to reset the lifting block 122, allowing subsequent glue injection operations to proceed. Simultaneously, as the lifting block 122 moves downward, the piston plate 132 slides downward along the inner surface of the piston cylinder 131, forcing the air inside the piston cylinder 131 into the air blowing pipe 134, which then blows the air through the air blowing hole 135 onto the outer surface of the bearing outer ring. At this time, the bearing outer ring is still rotating, thus drying the residual degreasing agent on the outer surface of the bearing outer ring during the downward movement of the lifting block 122. This ensures the dryness of the bearing outer ring and prevents residual degreasing agent from affecting the subsequent adhesion between the anaerobic adhesive and the bearing outer ring. This ensures that the anaerobic adhesive can firmly bond to the outer surface of the bearing outer ring, thereby ensuring the quality of the permanent magnet synchronous motor produced subsequently.

[0046] After degreasing, since the discharge end of the glue cartridge 114 is directly facing the bearing, the lifting cylinder 102 can be activated to slide the lifting plate 103 downwards, thereby moving the discharge end of the glue cartridge 114 toward the bearing of the rotor. Once the appropriate height is reached, the lifting cylinder 102 is closed. At this time, the air pump injects air into the glue cartridge 114 through the second air pipe 115, causing the discharge end of the glue cartridge 114 to inject glue onto the outer surface of the bearing. Simultaneously, the drive motor 93 is activated, causing the pneumatic block 94 to drive the rotor to rotate through the pneumatic chuck 95, allowing the glue cartridge 114 to inject glue onto the outer surface of the bearing. During the glue injection process, the electric slide table 91 is activated, causing the slide block 92 to move back and forth, thus causing the anaerobic glue injected by the glue cartridge 114 onto the outer surface of the bearing to be distributed in an "S" shape. The anaerobic adhesive distributed in an "S" shape on the outer surface of the bearing ensures that the anaerobic adhesive is covered in the 360° circumferential direction of the bearing. When the bearing is pressed in, the anaerobic adhesive is evenly squeezed towards the "crests" and "troughs" of the "S" shape. In addition, the anaerobic adhesive can also be squeezed in a direction perpendicular to the connection direction of the "crests" and "troughs". This can better fill the gaps between the bearing and the bearing housing and greatly reduce the risk of local missing adhesive. This forms a complete barrier between the outer ring of the bearing and the bearing housing with better sealing and more consistent locking force. It can ensure the formation of a complete, uniform, and bubble-free adhesive film, thereby providing the best anti-loosening, anti-fretting corrosion and sealing performance, and ultimately extending the service life of the permanent magnet synchronous motor and the bearing.

[0047] After the glue is applied, turn off the drive motor 93 and the electric slide table 91, and reset the glue cylinder 114. Then, the pneumatic clamp 95 will be unable to clamp and fix the rotor, and the rotor can be removed.

[0048] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
