Abstract

This application provides an integrated system for bonding plastic parts, relating to the field of automotive parts manufacturing and processing technology. It includes a gluing robot, a gluing and pressing structure, and a material handling auxiliary structure. The gluing and pressing structure includes a first positioning mold and a second positioning mold, both equipped with multiple vacuum suction cups. The material handling auxiliary structure includes clamping air rods, with an external rod connected to the movable end of each air rod. One end of the external rod is fitted with a rubber head.

Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing and processing technology, specifically a plastic parts bonding and integration system. Background Technology

[0002] The basic structure of a car includes an engine, chassis, body, and electrical system. The body is mounted on the chassis frame and is used for the driver and passengers to ride in or for carrying goods. The bodies of cars and buses are generally of a single piece, while the bodies of trucks are generally composed of a cab and a cargo box.

[0003] A car rear wing is a ducktail-like protrusion mounted on the rear of a car's trunk lid. It's part of the car's aerodynamic kit and its main function is to reduce lift at the rear of the vehicle, thus saving fuel and improving stability. A car rear wing typically consists of a spoiler and a wingplate, both of which are composed of inner and outer panels. During production, the inner and outer panels are glued together and cured at a heat source to ensure structural strength and connection stability.

[0004] A fully automatic adhesive bonding spoiler assembly structure, disclosed in Chinese patent document CN113184067B, features a continuous annular adhesive application frame area along the outer edge of the lower plate. After the robot applies adhesive within this frame area, the positioning posts on the inner surface of the upper plate are inserted one-to-one into the corresponding positioning holes in the lower plate, preventing misalignment of the upper plate. The adhesive then bonds the lower and upper plates together, resulting in a continuous bonding area and excellent bonding effect. The upper and lower plates are bonded solely with adhesive, eliminating the need for clips and screws.

[0005] An existing Chinese patent document, CN209776621 U, describes an automated assembly line for the adhesive bonding of a three-piece automotive spoiler. This line uses robots to pick up parts, perform flame treatment, adhesive application, and positioning and pressing. The number of employees at the two assembly stations has been reduced from six to two, significantly reducing labor costs. Furthermore, it improves the efficiency of workpiece assembly and increases the product qualification rate, while also demonstrating good consistency in assembly and auxiliary pressing.

[0006] However, in the process of implementing the above technical solution, the following technical problems were found:

[0007] Existing spoilers can improve gluing efficiency by using glue-applying robots, and can ensure the bonding effect after bonding the upper and lower plates. However, during the bonding process, the matching bonding structure requires manual positioning of the upper and lower plates to be bonded and disassembly of the bonded spoiler. This cannot keep the loading and unloading process smooth, resulting in low production efficiency for automated production lines and hindering the increase of product output. Summary of the Invention

[0008] To overcome the shortcomings of existing automated adhesive bonding systems and production lines where the bonding structure for upper and lower plates cannot ensure a smooth loading and unloading process, resulting in low production efficiency and hindering increased product output, this application provides an integrated plastic part bonding system. This system utilizes multiple vacuum suction cups on a contour-designed first and second positioning mold. When the inner plate is placed on the second positioning mold and the outer plate on the first positioning mold, the suction force generated by the vacuum suction cups secures the inner and outer plates. Upon removal of the bonded inner and outer plates, two clamping air rods control an external connecting rod to clamp the plates with rubber heads, facilitating rapid detachment of the first and second positioning molds from the inner and outer plates. Only manual handling is required, and the entire bonding process can be automated by a robotic arm, ensuring a fast, orderly, and smooth bonding operation.

[0009] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0010] A plastic parts bonding integration system includes an adhesive application robot, an adhesive application and pressing structure, and a material handling auxiliary structure. The adhesive application robot is used for automatic adhesive application.

[0011] Multiple adhesive coating and pressing structures are provided, and the multiple adhesive coating and pressing structures surround one side of the adhesive coating robot;

[0012] There are two material handling auxiliary structures, which are located on both sides of the adhesive coating and pressing structure.

[0013] The adhesive pressing structure includes a flipping part and a lifting part. The flipping part is assembled with an outer plate and movably connected to the top of the lifting part. The lifting part is assembled with an inner plate.

[0014] In one possible implementation, the outer panel coated with adhesive is rotated by a flipping mechanism, and the lifting mechanism moves from bottom to top to provide the necessary pressure for bonding the inner and outer panels, thereby bonding the inner panel coated with adhesive to the outer panel coated with adhesive.

[0015] In one possible implementation, the two material-retrieving auxiliary structures move from both sides toward the center to provide clamping force for the outer and inner panels to be bonded, thereby disengaging the flipping and lifting parts from them.

[0016] In one possible implementation, the bottom of the flipping section and the lifting section are provided with the same fixed bracket. Both ends of the fixed bracket are provided with safety light curtains, and both safety light curtains are located on the side away from the glue-applying robot. The flipping section includes a second mold frame, and flipping shafts are assembled and connected to both sides of the second mold frame. Two support frames are assembled and connected to the top of one side of the fixed bracket. The lifting section includes a first mold frame, and lifting cylinders are assembled and connected to the four corners of the bottom of the first mold frame. One end of the lifting cylinder is assembled and connected to the bottom of the fixed bracket. Slide rails are provided on both sides of the fixed bracket, and the slide rails support the first mold frame to move up and down inside the fixed bracket. The two support frames are respectively located at both ends of the fixed bracket. The two flipping shafts pass through the interior of the two support frames respectively. A motor is assembled and connected to one side of one flipping shaft, and the motor controls the second mold frame to flip between the two support frames through the flipping shaft.

[0017] In one possible implementation, the surface of the second mold frame is assembled with a first base, the surface of the first base is assembled with a first positioning mold, the top of the first mold frame is assembled with a second base, the surface of the second base is assembled with a second positioning mold, multiple vacuum suction cups are assembled with both the first and second positioning molds, the surfaces of the first and second positioning molds are both designed with contouring, the outer surface of the outer plate is fitted with the surface of the first positioning mold, and the inner surface of the inner plate is fitted with the surface of the second positioning mold.

[0018] In one possible implementation, both of the material handling auxiliary structures include a clamping air rod, the movable end of which is connected to an external rod, one end of which is sleeved with a rubber head, and the fixed end of which is assembled with a support plate. The two support plates are arranged symmetrically on the left and right, and the movable end of the clamping air rod protrudes from one side of the support plate.

[0019] In one possible implementation, a guide structure is provided between the two sides of the second base and the first base. The guide structure includes four support legs, which are divided into two groups and respectively assembled and connected to the surfaces of the two sides of the second base. The two support legs are externally movably sleeved with the same gantry. A spring is provided between the top of the support leg and the gantry. A seat frame is assembled and connected to the surfaces of both sides of the first base. An insert plate is assembled and connected to the bottom of the seat frame. A positioning slot is machined on the top of the gantry. Bevels are machined on the four sides of the bottom of the insert plate. The bevels are adapted to the inner wall of the positioning slot. The two ends of the first positioning mold are located inside the seat frame and supported by the inner wall of the seat frame.

[0020] In one possible implementation, the support leg has a groove machined inside, and the bottom of both ends of the gantry are pin-connected with limit pins, which are slidably connected inside the groove.

[0021] In one possible implementation, the support plate is Z-shaped, and two sub-frames are assembled and connected to the bottom of both sides of the fixed bracket. The two sub-frames on the same side are assembled and arranged vertically. The first mold frame is movably connected between the sub-frames on both sides, and one side of the support plate is assembled and connected to one sub-frame.

[0022] In one possible implementation, the bottom of the insert plate is machined with a storage slot, and the external rod is movably connected inside the storage slot. The external rod can also be movably connected to the inside of the gantry.

[0023] The beneficial effects of this application are as follows:

[0024] First, in this solution, by setting multiple vacuum suction cups on the first and second positioning molds of the contour design, when the inner plate is placed on the second positioning mold and the outer plate is placed on the first positioning mold, the suction force generated by the vacuum suction cups can be used to fix the inner plate and the outer plate, without the need for staff to control the clamps.

[0025] Secondly, in this solution, the second mold frame is controlled by a motor connected to the flipping shaft frame, thereby driving the first positioning mold on the first base to flip. When the first mold frame is controlled by a lifting cylinder to drive the second positioning mold on the second base to move to the top, the positioning slot on the gantry and the inclined surface on the insert plate are used to correct the relative position of the first positioning mold and the second positioning mold. This facilitates the bonding of the inner and outer panels with adhesive, thereby ensuring bonding accuracy. During the bonding process, there is no need to stop the equipment for maintenance, which helps to ensure product quality and production efficiency.

[0026] Thirdly, in this solution, when the inner and outer panels that have been bonded are removed, the two clamping air rods control the external connecting rods to drive the rubber heads to clamp them, which can help the first positioning mold and the second positioning mold to quickly detach from the inner and outer panels. Only the staff needs to pick them up. The stage in the bonding process where the staff participates can be replaced by a robotic arm, which helps to ensure that the entire bonding work is carried out quickly, orderly and smoothly.

[0045] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0046] Example 1:

[0047] This embodiment describes the specific structure of a plastic part bonding integration system, which can be referred to in detail below. Figures 1-8 , Figure 10 As shown, it includes a glue-applying robot 1, multiple glue-applying and pressing structures 2 (surrounding one side of the glue-applying robot 1) and two material-picking auxiliary structures 4. The two material-picking auxiliary structures 4 are located on both sides of the glue-applying and pressing structure 2. The glue-applying and pressing structure 2 includes a flipping part and a lifting part. An outer plate is assembled and connected to the flipping part and is movably connected to the top of the lifting part. An inner plate is assembled and connected to the lifting part.

[0048] The inner surface of the outer panel is coated with adhesive, which can control the top-facing adhesive side to face the bottom when the outer panel is installed on the flip-up part.

[0049] Meanwhile, the outer surface of the inner panel is coated with adhesive. When the inner panel is installed on the lifting part, it can be directly opposite the adhesive surface of the outer panel facing the bottom. When the lifting part moves from the bottom to the top, it can bond the adhesive-coated surface of the inner panel with the adhesive-coated surface of the outer panel, and provide the necessary pressure for bonding the inner and outer panels, ensuring that the adhesive areas of the inner and outer panels are tightly fitted.

[0050] Secondly, the two material picking auxiliary structures 4 are located between the two sides of the inner and outer plates after the bonding is completed. When the two material picking auxiliary structures 4 move from the sides to the center to apply pressure to the inner and outer plates, they can be demolded at the bottom of the lifting part and the inner plate connection area, and disengage from the outer plate connection area when the flipping part flips, thereby completing the demolding work.

[0051] like Figure 3 , 4 As shown, the bottom of the flipping part and the lifting part are provided with the same fixed bracket 211. The flipping part includes a second mold frame 209. Both sides of the second mold frame 209 are assembled and connected with flipping shaft frames 206. Two support frames 205 are assembled and connected to the top of one side of the fixed bracket 211. The lifting part includes a first mold frame 208. Lifting cylinders 210 are assembled and connected to the four corners at the bottom of the first mold frame 208.

[0052] One end of the lifting cylinder 210 is assembled and connected to the bottom of the fixed bracket 211, as shown in the figure. By setting slide rails on both sides of the fixed bracket 211, the slide rails are located at both ends of the first mold frame 208. During the up and down movement of the first mold frame 208, support can be formed on both sides of the first mold frame 208 to ensure that the first mold frame 208 moves vertically up and down.

[0053] At the same time, such as Figure 3 As shown, two support frames 205 are respectively set at both ends of the fixed bracket 211. When two flipping shaft frames 206 are respectively passed through the interior of the two support frames 205, and a motor is assembled and connected to one side of one flipping shaft frame 206, the motor can control one flipping shaft frame 206 to rotate. When the flipping shaft frame 206 rotates inside the support frame 205, the second mold frame 209 can be controlled to flip between the two support frames 205 through the flipping shaft frame 206.

[0054] Secondly, such as Figure 1 As shown, safety light curtains 3 are provided at both ends of the fixed bracket 211, and both safety light curtains 3 are located on the side away from the glue-applying robot 1. By assembling the electrical switch that controls the operation of the glue-applying robot 1 and the glue-applying pressing structure 2 on the safety light curtains 3, it is possible to prevent workers from approaching the first mold frame 208, and effectively avoid injury to workers during the opening and closing of the second mold frame 209 and the first mold frame 208.

[0055] Example 2:

[0056] Based on Example 1, this example describes the specific structure of the second mold frame 209 and the first base 201, as follows: Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the surface of the second mold frame 209 is assembled with the first base 201, the surface of the first base 201 is assembled with the first positioning mold 203, the top of the first mold frame 208 is assembled with the second base 202, and the surface of the second base 202 is assembled with the second positioning mold 204.

[0057] Among them, such as Figure 6 and Figure 7 As shown, the surfaces of the first positioning mold 203 and the second positioning mold 204 are both designed with contouring. After the outer surface of the outer plate is made to fit with the surface of the first positioning mold 203 and the inner surface of the inner plate is made to fit with the surface of the second positioning mold 204, the gap in the installation area can be eliminated, and the second mold frame 209 is prevented from flipping to the top of the first mold frame 208. During the process of the first mold frame 208 moving to the top, the pressure generated by the first mold frame 208 and the second mold frame 209 approaching each other will cause local deformation of the inner and outer plates.

[0058] Secondly, such as Figure 6 and Figure 7As shown, multiple vacuum suction cups 212 are assembled and connected to both the first positioning mold 203 and the second positioning mold 204. When the surface of the second positioning mold 204 is attached to the inner surface of the inner plate and the surface of the first positioning mold 203 is attached to the outer surface of the outer plate, the suction force of the multiple vacuum suction cups 212 can be used to fix the outer plate to the first positioning mold 203 and fix the inner plate to the second positioning mold 204.

[0059] Example 3:

[0060] Based on Examples 1 and 2, this example describes the specific structure of the material handling auxiliary structure 4, such as... Figure 2 and 4 As shown, both material handling auxiliary structures 4 include a clamping air rod 403. The movable end of the clamping air rod 403 is connected to an external rod 401. One end of the external rod 401 is connected to a rubber head 402 in a sleeve-type manner. The fixed end of the clamping air rod 403 is assembled with a support plate 404.

[0061] The two support plates 404 are symmetrically arranged on the left and right. When the movable end of the clamping air rod 403 passes through one side of the support plate 404, the clamping air rod 403 can be activated to push the external rod 401 with its movable end to drive the rubber head 402 to move closer to one side of the inner and outer plates, so as to facilitate the clamping of the inner and outer plates that have been glued.

[0062] At this time, when the first mold frame 208 moves to the bottom under the control of four lifting cylinders 210 and the support frame 205 connected to one side of the second mold frame 209 rotates under the control of the motor, the inner plate and the second positioning mold 204 can be disconnected and the outer plate and the first positioning mold 203 can be disconnected when the multiple vacuum suction cups 212 release the suction state.

[0063] Secondly, such as Figure 4 As shown, the support plate 404 is Z-shaped, and two sub-frames 207 are assembled and connected to the bottom of both sides of the fixed bracket 211. One side of the support plate 404 is assembled and connected to one sub-frame 207, and the two sub-frames 207 on the same side are assembled and set up vertically. Since the first mold frame 208 is movably connected between the sub-frames 207 on both sides, when the first mold frame 208 is controlled by four lifting cylinders 210 to move to the bottom, it can push the second positioning mold 204 assembled on the top of the second base 202 to move to the bottom.

[0064] Example 4:

[0065] Based on embodiments 1, 2, and 3, this embodiment describes the specific structure of the guide structure 5 disposed between the two sides of the second base 202 and the first base 201, such as... Figures 8-11As shown, the guide structure 5 includes four support legs 504, which are divided into two groups and respectively assembled and connected to the surfaces on both sides of the second base 202. The two support legs 504 are externally movably sleeved with the same gantry 503. A spring 509 is provided between the top of the support leg 504 and the gantry 503. A seat frame 502 is assembled and connected to both sides of the first base 201. A plug plate 501 is assembled and connected to the bottom of the seat frame 502. A positioning slot 505 is machined on the top of the gantry 503.

[0066] In order to enable the bottom of the base 502 to smoothly cut into the interior of the positioning slot 505 after the first mold frame 208 drives the first base 201 to rotate, and to position the first base 201 so that the first base 201 is directly above the second base 202, bevels are machined on all four sides of the bottom of the insert plate 501. These bevels are adapted to the inner wall of the positioning slot 505, thereby positioning the base 502. This helps to eliminate the problem that when the first mold frame 208 rotates around the flipping shaft 206 for a long time, the movement gap between the flipping shaft 206 and the support frame 205 causes the first positioning mold 203 and the second positioning mold 204 to have low mold closing accuracy.

[0067] Meanwhile, when fixing the insert plate 501 to the first base 201, the two ends of the first positioning mold 203 can be located inside the frame 502 and supported by the inner wall of the frame 502. This allows the first positioning mold 203 to be stably assembled with the first base 201. With the help of the insert plate 501 and the frame 503 working together, the bolts connecting the first base 201 and the second mold 209 are prevented from loosening during the rotation of the first positioning mold 203 with the second mold frame 209, thus reducing the accuracy of the assembly of the first base 201 and the second mold frame 209.

[0068] In addition, after the gantry 503 corrects the position of the flipped insert 501, it can correct the position of the first positioning mold 203 relative to the second positioning mold 204. When the four lifting cylinders 210 control the second mold frame 209 to move to the top, the second base 202 drives the support leg 504 and the gantry 503 to move to the top, so that the spring 509 supported between the support leg 504 and the gantry 503 is compressed, thereby causing the inner plate fixed on the second positioning mold 204 to move closer to the outer plate on the first positioning mold 203, so as to perform the bonding work.

[0069] Secondly, after bonding the outer panel and the inner panel, clamping cylinders are used on both sides of the first positioning mold 203 and 24 to ensure that the bonding area of ​​the first positioning mold 203 and the second positioning mold 204 is tightly bonded to avoid the glue coming off during the curing process, and the bonding area is heated from all sides of the first positioning mold 203 and the second positioning mold 204.

[0070] Furthermore, to prevent the gantry 503 from detaching from the outside of the two support legs 504 when the gantry 503 and support legs 504 are assembled on the second base 202, a sliding groove 507 is machined inside the support legs 504. The bottom of both ends of the gantry 503 are connected by a pin-type limit pin 508. When the gantry 503 is not connected to the insert plate 501, the spring 509 relaxes to support the limit pin 508 on the top of the sliding groove 507. When the gantry 503 is connected to the insert plate 501 and pressure is generated, the spring 509 is compressed, and at this time, the limit pin 508 slides inside the sliding groove 507.

[0071] Furthermore, to prevent interference between the insert plate 501 and the external rod 401 during the connection process between the insert plate 501 and the gantry 503, and to allow the two material handling auxiliary structures 4 to apply pressure to the inner and outer plates that have completed the bonding work, a storage slot 506 is machined at the bottom of the insert plate 501 so that the external rod 401 can be movably connected inside the storage slot 506.

[0072] Meanwhile, depending on the different contouring second positioning mold 204 and first positioning mold 203, the support plate 404 can be assembled onto the bottom subframe 207, so that the external rod 401 can be movably connected to the inside of the gantry 503.

[0073] The specific work steps are as follows:

[0074] S1. A motor connected to a flipping shaft 206 controls the flipping shaft 206 to drive the second mold frame 209 to rotate between two support frames 205, so that the first positioning mold 203 and the second positioning mold 204 are at a 90-degree angle. Figure 12 As shown, the inner plate is placed on the second positioning mold 204 so that the inner surface of the inner plate is in contact with the surface of the second positioning mold 204, and the outer plate is placed on the first positioning mold 203 so that the outer surface of the outer plate is in contact with the surface of the first positioning mold 203. Multiple vacuum suction cups 212 are used to adsorb the inner plate and the outer plate respectively.

[0075] S2. The motor-controlled tilting shaft 206 drives the second mold frame 209 to rotate between the two support frames 205, so that when the surfaces of the second positioning mold 204 and the first positioning mold 203 face the top, as shown... Figure 1 and Figure 2 As shown, the glue-applying robot 1 applies glue to the outer surface of the inner panel and the inner surface of the outer panel successively.

[0076] S3. The motor-controlled flipping shaft 206 drives the second mold frame 209 to rotate between the two support frames 205, causing the first base 201 assembled on the second mold frame 209 to drive the first positioning mold 203 to flip towards the top of the first mold frame 208, so that the outer plate on the first positioning mold 203 faces the inner plate on the second positioning mold 204, as shown. Figure 8 As shown;

[0077] S4. The first base 201 drives the bracket 502 and the insert plate 501 to rotate, so that the insert plate 501 cuts into the positioning slot 505 on the bracket 503 by means of the inclined surface machined on it, thereby correcting the position of the first base 201 relative to the second base 202. Figure 9 As shown;

[0078] S5. Four lifting cylinders 210 push the second base 202 to move the second positioning mold 204 to the top. The opposing force between the insert plate 501 and the gantry 503 compresses the spring 509 between the support leg 504 and the gantry 503, thereby performing the bonding work between the inner plate of the second positioning mold 204 and the outer plate of the first positioning mold 203.

[0079] S6. Use a clamping cylinder to tightly bond the inner and outer panels on both sides, and heat and cure them from all sides of the inner and outer panels.

[0080] S7. After the bonding and curing process is completed, a single spoiler is formed. Activate the two clamping air rods 403 so that their movable ends extend from the inside of the fixed ends. The clamping air rods 403 control the external rod 401 to move the rubber head 402 towards one side of the inner and outer plates, clamping the spoiler. Figure 4 As shown, at this time, the first positioning mold 203 and the second positioning mold 204 are at a 90-degree angle;

[0081] S8. Release the suction force of multiple vacuum suction cups 212 on the spoiler, so that the lifting cylinder 210 controls the second base 202 to drive the second positioning mold 204 to move to the bottom, and the motor controls the flipping shaft frame 206 to drive the second mold frame 209 to rotate, so that the first base 201 drives the first positioning mold 203 to flip.

[0082] S9. Retract the movable ends of the two clamping air rods 403 into the interior of the fixed ends and remove the spoiler.

[0083] By adopting the above technical solution:

[0084] The above design first places the inner and outer panels with adhesive on the second positioning mold 204 and the first positioning mold 203 respectively. After the contact surfaces are brought into contact, the suction force generated by the vacuum suction cup 212 is used to fix the inner and outer panels, without the need for clamps.

[0085] Then, on the safety light curtain 3 on the side of the glue-applying and pressing structure 2 away from the glue-applying robot 1, an electrical switch is operated to prevent workers from approaching the first mold frame 208, effectively avoiding injury to workers during the opening and closing of the second mold frame 209 and the first mold frame 208;

[0086] Simultaneously, a motor connected to a flipping shaft 206 is activated to control the flipping shaft 206 to drive the second mold frame 209 to rotate between the two support frames 205. This causes the first base 201, which is assembled on the second mold frame 209, to drive the first positioning mold 203 to flip towards the top of the first mold frame 208. This allows the insert plate 501 to cut into the positioning slot 505 on the mold frame 503 using the inclined surface machined on it, thereby correcting the position of the first base 201 relative to the second base 202. This can avoid the problem of low mold closing accuracy between the first positioning mold 203 and the second positioning mold 204 when the first mold frame 208 rotates around the flipping shaft 206 for a long period of time due to the movement gap between the flipping shaft 206 and the support frame 205.

[0087] Secondly, the four lifting cylinders 210 are activated, which push the second base 202 to move the second positioning mold 204 to the top. Because the insert plate 501 and the gantry 503 are connected, the spring 509 is compressed between the support leg 504 and the gantry 503 by means of the opposing force between them. Finally, the adhesive surface of the inner plate of the second positioning mold 204 is pressed against the adhesive surface of the outer plate of the first positioning mold 203, and the bonding work of the inner plate of the second positioning mold 204 and the outer plate of the first positioning mold 203 is carried out. This can accurately position the inner plate and the outer plate without the need for staff intervention.

[0088] After the inner and outer panels are bonded together as a single spoiler, the two clamping air rods 403 are activated to control the corresponding external rods 401 to drive the rubber heads 402 to clamp the spoiler. The second base 202 is controlled by the first mold frame 208 to drive the second positioning mold 204 to move to the bottom, and the first base 201 is controlled by the second mold frame 209 to drive the first positioning mold 203 to flip over, and then the spoiler is removed between the two rubber heads 402.

[0089] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
