Description

Technical Field

[0001] This invention relates to the field of circuit board technology, specifically to a circuit board fixture and a circuit board production system. Background Technology

[0002] With the rapid development of electronic technology, circuit boards (PCBs), as an important carrier of electronic products, are widely used in fields such as computers, communication equipment, automotive electronics, and semiconductor manufacturing. PCB production typically involves multiple processes including copper plating, etching, drilling, electroplating, soldering, and testing. During processing and testing, PCB fixtures are needed to fix and position the PCBs to ensure processing accuracy and assembly quality. Especially in the semiconductor device or integrated circuit assembly stage, PCB fixtures effectively prevent PCB displacement and improve the stability of soldering and packaging, making them an indispensable auxiliary device in the production process.

[0003] However, most common circuit board fixtures currently use mechanical grippers to hold and fix the circuit boards. When it is necessary to replace or remove the circuit board, it is usually necessary to manually loosen or remove the grippers distributed at the edge of the circuit board one by one. This operation is not only time-consuming and labor-intensive, but also prone to deformation or scratches on the edge of the circuit board during repeated disassembly and assembly, which is not conducive to the assembly and testing of precision electronic components and affects production efficiency. In addition, the gripping part of the existing fixture is usually located at the edge of the circuit board, but during the fixing process, part of the gripping part often covers the surface of the circuit board, which makes it impossible to perform processing operations such as drilling, etching or soldering in that area, thus limiting the overall processing range and flexibility of the circuit board. If the circuit board is fixed by adhesive, although the problem of the gripping part obstructing the processing area can be avoided, the adhesive layer must be removed manually after processing, which is not only cumbersome, but also prone to leaving adhesive residue on the surface of the circuit board or damaging the circuit board, further affecting product quality and production efficiency.

The first elastic element is sleeved on the cavity.

[0015] An air passage is provided inside the pusher, and the air passage gradually diffuses at the end away from the cavity.

[0016] It also includes a locking assembly disposed within the base body, the locking assembly being used to lock the pusher.

[0017] Preferably, the locking assembly includes a locking block and a second elastic element. The pushing member has a groove for the locking block to extend into. The locking block has a guide protrusion with an inclined surface on the side near the cavity. The cavity has a driving portion matching the inclined surface on the side near the locking block. The base has a mounting groove, and the locking block is slidably mounted in the mounting groove. The second elastic element is disposed in the mounting groove, providing elastic force for the locking block to extend into the groove.

[0018] In a second aspect of the invention, a circuit board manufacturing system is provided, including the circuit board fixture and drive mechanism described above.

[0019] The driving mechanism includes a lifting plate, a cylinder, a support base, a guide rod, a first suction cup, and a second suction cup. The cylinder is mounted on the lifting plate, and its output end is fixedly connected to the lifting plate. The guide rod is fixedly connected to the lifting plate, passes through the support base, and is slidably connected to the support base.

The surface of the fixing part is provided with an adhesive layer. When the adhesive layer is under pressure, it forms a firm adhesion to the surface of the circuit board, so that the circuit board is kept in a stable state on the fixture. It can effectively prevent displacement caused by vibration, airflow or mechanical impact, thereby ensuring the accuracy and reliability of processes such as drilling, etching or installing semiconductor devices on the circuit board.

[0024] The board release assembly is used to separate the circuit board from the substrate after processing. The pusher can slide within the substrate along its axial direction. After the circuit board processing is complete, the operator can apply external force to the substrate, causing displacement of the substrate relative to the pusher, prompting the front end of the pusher to extend beyond the first surface, thereby lifting the circuit board adhered to the fixing part. Because the pusher is elastically pre-tightened by the first elastic element, its tip can apply a uniform pushing force to the circuit board after it extends, gradually detaching the circuit board from the adhesive layer and avoiding bending or damage to the circuit board due to sudden peeling.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0030] In the manufacturing and processing of integrated circuits and semiconductor devices, as the integration level of semiconductor devices continues to increase, the component layout on circuit boards becomes increasingly dense, and the requirements for processing accuracy and cleanliness become increasingly stringent. Traditional fixtures that rely on manual disassembly or fixation can no longer meet the demands of high-precision processes. This invention enables the stable fixation and automatic detachment of circuit boards without damaging the circuit boards and their integrated components. This system can be used in multiple processes such as semiconductor packaging, chip mounting, soldering, testing, and finished product inspection, and is particularly suitable for the automated operation of easily deformable circuit substrates such as flexible circuit boards and high-density interconnect boards. This invention effectively avoids electrostatic interference, localized stress concentration, and surface contamination problems caused by manual disassembly, thereby ensuring the structural integrity and electrical performance reliability of integrated circuits and semiconductor devices throughout the entire production process, and achieving automated, precise, and safe control of the microelectronics manufacturing process.

[0031] Example 1 like Figures 1 to 14 As shown, in a first aspect of the present invention, a circuit board fixture is provided. The circuit board fixture includes a base 1 and a stripping assembly 2; the base 1 includes a first surface 11 and a second surface 12 disposed opposite to each other, the first surface 11 being provided with a fixing portion 13 for fixing the circuit board; the stripping assembly 2 includes a pushing member 21 and a first elastic element 22, the pushing member 21 passing through the base 1 and slidably connected to the base 1, the first elastic element 22 being connected to the pushing member 21 and located on the side where the second surface 12 is located.

[0032] When the circuit board is fixed to the fixing part 13 of the base 1, the pusher 21 is flush with or embedded in the base 1. When the pusher 21 is subjected to a force from the second surface 12 toward the first surface 11, the pusher 21 performs the action of detaching the circuit board from the base 1. At least a portion of the pusher 21 protrudes from the first surface 11 of the base 1.

[0033] In this embodiment, the substrate 1 is used to support the circuit board and provide a stable support platform. The first surface 11 is a processing surface that directly contacts the circuit board. The fixing part 13 provided on it can be used to precisely define the placement position of the circuit board, thereby ensuring that the circuit board is in a consistent position during processing and assembly, and avoiding welding errors or device misalignment caused by offset. The surface of the fixing part 13 is provided with an adhesive layer, which forms a firm adhesion to the surface of the circuit board when under pressure, keeping the circuit board in a stable state on the fixture. This effectively prevents displacement caused by vibration, airflow, or mechanical impact, thereby ensuring the accuracy and reliability of processes such as drilling, etching, or mounting semiconductor devices on the circuit board.

[0034] The board removal assembly 2 is used to separate the circuit board from the substrate 1 after processing. The pusher 21 can slide within the substrate 1 along its axial direction. After the circuit board processing is completed, the operator can apply external force to the substrate 1, causing the substrate 1 to displace relative to the pusher 21, causing the front end of the pusher 21 to extend out of the first surface 11, thereby lifting the circuit board adhered to the fixing part 13. Because the pusher 21 is kept elastically pre-tightened by the first elastic element 22, when the pusher 21 extends, its top end can apply a uniform pushing force to the circuit board, causing the circuit board to gradually detach from the adhesive layer, avoiding bending or damage to the circuit board due to sudden peeling.

[0035] During the pushing process, the first elastic element 22 acts as a buffer and reset mechanism. When the external force is released, the first elastic element 22 automatically returns to its original state, driving the pushing component 21 back to its initial position, completing one board removal cycle. In this embodiment, the circuit board disassembly process does not require manual removal of the circuit board, which reduces operational intensity and prevents warping or cracking caused by uneven force on the circuit board surface, ensuring the integrity of the product's appearance and performance. Simultaneously, the absence of clamping components on the circuit board surface keeps the surface intact, facilitating circuit board processing and the assembly of integrated circuits and semiconductor devices.

[0036] In this embodiment, the base 1 has a mounting notch 15 for mounting the adjusting member 14 and providing it with adjustable movement space. The side of the adjusting member 14 facing away from the second surface 12 is on the same plane as the first surface 11. The adjusting member 14 not only participates in forming the support surface for the circuit board, but also has the characteristic of being position-adjustable, so that the fixture can flexibly adjust the size of the circuit board accommodating space according to circuit boards of different sizes or shapes, thereby realizing the compatible use of the integrated fixture for circuit boards of multiple specifications.

[0037] like Figure 2 As shown, in actual use, by changing the position of the adjusting member 14 in the mounting notch 15, the size of the space defined by the first surface 11 of the substrate 1 can be matched with the external dimensions of the circuit board to be processed. When the circuit board size is large, the adjusting member 14 slides outward to increase the accommodating space; when the circuit board size is small, the adjusting member 14 moves inward to reduce the space, thus achieving reliable positioning of the circuit board. Since the mounting notch 15 has fully considered the arrangement area of ​​semiconductor devices on the circuit board during design, the movement path of the adjusting member 14 can effectively avoid the semiconductor devices on the circuit board body, thereby preventing the precision components from being squeezed, crushed, or scratched during adjustment or clamping, ensuring the safety and integrity of the circuit board in the fixed state.

[0038] In this embodiment, to make the movement of the adjusting member 14 more stable and precise, a guide member 16 is provided on the base 1, and the adjusting member 14 and the guide member 16 are slidably connected. A groove 161 is provided on the guide member 16, which provides a clear guiding path for the movement of the adjusting member 14, restricting the adjusting member 14 to move smoothly in a predetermined direction and preventing it from deviating or tilting during adjustment. An adjusting bolt 141 is threadedly connected to the adjusting member 14, passing through the groove 161 and threadedly engaging with the adjusting member 14, thereby forming an adjustable and lockable connection structure.

[0039] During adjustment, the operator can first loosen the adjusting bolt 141, allowing the adjusting component 14 to slide within the groove 161 of the guide component 16. Then, by manually moving the adjusting component 14 along the groove 161, it is moved to a position matching the target circuit board size. Once the adjusting component 14 is in the appropriate position, the adjusting bolt 141 is tightened to secure it to the guide component 16, thus locking and fixing the adjusting component 14. This structural design makes the adjustment process simple and intuitive, enabling rapid adaptation to different circuit board specifications without changing the main fixture body. This improves the versatility and reusability of the fixture, while ensuring consistent fixing accuracy during the processing of circuit boards of different sizes.

[0040] In this embodiment, the circuit board fixture further includes a support member 17, which forms part of the first surface 11 with the side facing away from the second surface 12 within the circuit board receiving space; a board release assembly 2 is provided on the support member 17. When the circuit board is placed on the fixture, the support member 17 can provide support for the circuit board, especially the central area of ​​the flexible circuit board, so that the circuit board remains flat during processing or assembly, thereby effectively preventing collapse or deformation caused by its own weight or uneven force.

[0041] like Figure 2 and Figure 3 As shown, the support member 17 is used to support the circuit board. Since the circuit board also includes a flexible circuit board, the support member 17 is designed to prevent the circuit board from collapsing during transportation or processing. It provides a certain load-bearing capacity for the circuit board, ensuring easy processing and facilitating the assembly of integrated circuits and semiconductor devices. A stripping assembly 2 is provided on the support member 17. By placing the stripping assembly 2 on the support member 17, the pushing force can be directly applied to the central area of ​​the circuit board, enabling uniform and stable stripping after processing. Compared to stripping only from the edge, this structure effectively prevents the flexible circuit board from bending or stretching due to localized force concentration during stripping, thereby improving the safety and reliability of the stripping process. The position adjustment method of the support member 17 is the same as that of the adjustment member 14, and will not be described in detail here.

[0042] In this embodiment, the substrate 1 further includes a support plate 18; the support plate 18 is detachably installed within the mounting notch 15, and the side of the support plate 18 facing away from the second surface 12 forms a portion of the first surface 11. This support plate 18 is mainly used to support the flexible circuit board. During the processing of the flexible circuit board, due to its thin structure and weak rigidity, if it is placed directly on an ordinary substrate, it is very easy to affect the processing accuracy due to localized sinking or deformation. By providing a detachable support plate 18 within the mounting notch 15, additional support can be provided when the flexible circuit board is placed, ensuring that the overall force on the flexible circuit board is uniform and that it remains flat, thereby guaranteeing the processing and assembly quality.

[0043] The detachable design of the support plate 18 provides high flexibility for different applications. When the fixture is used for rigid circuit board processing, the support plate 18 can be removed to make room for more space; when the fixture is used for flexible circuit boards, the support plate 18 can be quickly installed to enhance the support effect. In addition, the support plate 18 can be replaced according to different circuit board specifications, facilitating maintenance and cleaning.

[0044] Example 2 like Figures 5 to 11As shown, the difference between this embodiment and Embodiment 1 is that the ejector assembly 2 further includes a cavity 23 and a guide sleeve 24. The cavity 23 is sleeved on the pusher 21, and the pusher 21 is slidably connected to the cavity 23. The guide sleeve 24 is fixedly connected to the base 1 and is located on the side where the second surface 12 is located. The cavity 23 extends into the guide sleeve 24 and is slidably connected to the guide sleeve 24. Through the setting of this guide structure, the cavity 23 maintains a stable axial direction when moving up and down, avoiding the problem of uneven pushing due to skewing or friction, thereby ensuring that the pusher 21 moves smoothly in the vertical direction during the ejection process.

[0045] The first elastic element 22 is a spring, sleeved on the cavity 23. One end of the first elastic element 22 is connected to the guide sleeve 24, and the other end is connected to the cavity 23, providing elastic force to the cavity 23 away from the second surface 12. Elastic support for the cavity 23 is achieved through the compression and release of the first elastic element 22. When the cavity 23 is subjected to external force, the first elastic element 22 is compressed and stores elastic potential energy; when the external force is released, the first elastic element 22 returns to its original shape and releases the elastic force, driving the cavity 23 and the pusher 21 back to their initial position. This structural design enables the release plate action to have an automatic reset function, ensuring the device is stable and reliable during continuous operation.

[0046] The pusher 21 has an air passage 211 inside, which gradually diffuses at the end away from the cavity 23. This diffused air passage design can create a pressure buffer during airflow, making the airflow more uniform and gentle when ejected. Air can be blown upward along the internal channel of the pusher 21, pre-blowing and separating the adhesive layer between the circuit board and the fixing part 13 before the push operation. Due to the permeability of the airflow, it can penetrate and diffuse through the tiny gap between the circuit board and the adhesive layer, thereby achieving smooth pneumatic debonding, allowing the circuit board to gradually separate from the substrate 1, reducing the risk of impact and deformation caused by direct mechanical push.

[0047] The circuit board fixture also includes a locking component 3 disposed within the base 1, the locking component 3 being used to lock the pusher 21.

[0048] In the initial state, the locking assembly 3 locks the push rod 21, with the upper end of the push rod 21 flush with or lower than the first surface 11. When the circuit board needs to be removed from the fixture, the cavity 23 is brought into contact with the plane first, and downward pressure is applied to the base 1, causing the base 1 to move downward. At this time, the cavity 23 moves upward relative to the base 1, and the first elastic element 22 is compressed. Since the push rod 21 is locked, the air in the cavity 23 is compressed and enters the air passage 211. The compressed air is ejected upward through the air passage 211, thereby applying a uniform airflow to the bottom of the circuit board. By blowing air onto the circuit board, the circuit board gradually detaches from the fixing part 13, achieving initial detachment. Since air has a certain penetrating ability, it can achieve a smooth debonding effect. As the cavity 23 continues to move upward, the cavity 23 drives the locking assembly 3 to release the locking of the push rod 21. Subsequently, the cavity 23 drives the push rod 21 to move upward, and the push rod 21 will extend out of the first surface 11, applying an upward pushing force to the circuit board, thereby pushing the entire circuit board away from the base 1, achieving complete board removal.

[0049] After the board removal process is completed, the pusher 21, under the elastic recovery action of the first elastic element 22, drives the cavity 23 to gradually reset. As the external force is released, the first elastic element 22 releases its elastic potential energy, pushing the cavity 23 back to its initial position, so that the board removal assembly 2 returns to the standby state. During the reset process of the cavity 23, since the circuit board has detached from the upper surface of the pusher 21, the upper end of the air passage 211 is in an open state. Therefore, outside air can smoothly enter the interior of the cavity 23 through the air passage 211 to replenish the air pressure change in the cavity during reset, thereby preventing the formation of negative pressure in the cavity 23.

[0050] In this embodiment, the locking assembly 3 includes a locking block 31, a second elastic element 32, and a rod 33. The pusher 21 is provided with a slot 212 for the locking block 31 to extend into. The locking block 31 is provided with a guide protrusion 311. The guide protrusion 311 has an inclined surface on the side near the cavity 23. The cavity 23 has a driving part 231 that matches the inclined surface on the side near the locking block 31. The base 1 has a mounting groove 19. The locking block 31 is slidably installed in the mounting groove 19. The rod 33 is fixedly installed in the mounting groove 19. The rod 33 is inserted into the locking block 31 and slidably connected to the locking block 31. The second elastic element 32 is provided in the mounting groove 19 to provide elastic force for the locking block 31 to extend into the slot 212.

[0051] In the initial state, such as Figure 9As shown, the locking block 31 extends into the slot 212, thus restricting the pusher 21 to a predetermined position and preventing it from moving upwards. At this time, the ejector assembly 2 is in a locked state, ensuring that the circuit board remains stable during the processing stage and will not be lifted due to accidental contact or external force. When the ejection operation begins, the cavity 23 moves upwards under the action of external force, and the drive part 231 of the cavity 23 gradually contacts the inclined surface of the guide protrusion 311 and applies a pushing force along the inclined surface, causing the locking block 31 to slide along the mounting groove 19 and gradually exit the slot 212. As the locking block 31 exits, the second elastic element 32 is compressed and stores elastic potential energy, and the insertion rod 33 simultaneously slides into the interior of the locking block 31, constraining and guiding its movement trajectory, thereby making the locking action release process smooth and without jamming.

[0052] When the locking block 31 is fully retracted into the mounting slot 19, the locking assembly 3 completes the unlocking action. At this time, the pusher 21 is released from its restriction and begins to move upward under the continuous upward drive of the cavity 23. The upper end of the pusher 21 gradually extends out of the first surface 11 and applies a uniform pushing force to the circuit board, so that the circuit board is completely separated from the fixing part 13, and complete board removal is achieved.

[0053] Example 3 like Figures 12 to 14 As shown, in a second aspect of the present invention, a circuit board manufacturing system is provided, including the circuit board fixture and drive mechanism 4 described above; The driving mechanism 4 includes a lifting plate 41, a cylinder 42, a support base 43, a guide rod 44, a first suction cup 45, and a second suction cup 46. The cylinder 42 is mounted on the lifting plate 41, and its output end is fixedly connected to the lifting plate 41. The guide rod 44 is fixedly connected to the lifting plate 41 and passes through the support base 43, and is slidably connected to the support base 43. The first suction cup 45 is fixedly connected to the lifting plate 41 and is used to adsorb the substrate 1. The second suction cup 46 is slidably connected to the lifting plate 41 and is used to adsorb the circuit board. The height of the suction nozzle of the second suction cup 46 is higher than the height of the suction nozzle of the first suction cup 45. When the lifting plate 41 moves downward under the drive of the cylinder 42, due to the height difference, the second suction cup 46 can contact the circuit board in time after the push rod 21 lifts it up, forming a reliable adsorption effect and realizing the automatic transfer of the circuit board from the substrate 1.

[0054] In use, the first suction cup 45 adsorbs the substrate 1. By controlling the movement of the first suction cup 45, the substrate 1 is driven to move. When it moves to the detachment position, the output end of the control cylinder 42 extends, and the output end of the cylinder 42 drives the lifting plate 41 to move down. The lifting plate 41 drives the first suction cup 45 and the second suction cup 46 to move down. When the push rod 21 contacts the contact surface, as the output end of the cylinder 42 continues to extend and the lifting plate 41 continues to move down, the push rod 21 will lift the circuit board. With the height difference between the suction nozzles of the first suction cup 45 and the second suction cup 46, the circuit board will contact the second suction cup 46. Then the second suction cup 46 will adsorb the circuit board. Then the first suction cup 45 will release its adsorption on the substrate 1. Next, the carrying base 43 is driven to move, carrying the circuit board to move for the next production process.

[0055] The lifting plate 41 has a strip-shaped notch 411 for the second suction cup 46 to slide. The second suction cup 46 passes through the strip-shaped notch 411 and can slide within the strip-shaped notch 411. Two locking nuts 461 are fitted on the second suction cup 46 and are threadedly connected to the second suction cup 46. The two locking nuts 461 are located on the upper and lower surfaces of the lifting plate 41, respectively.

[0056] To accommodate circuit boards of different specifications and sizes, the locking nut 461 can be loosened, and then the second suction cup 46 can be slid within the strip-shaped notch 411. After adjusting the second suction cup 46 to the position that matches the circuit board, the locking nut 461 can be tightened to adjust the position of the second suction cup 46.

[0057] In this embodiment, the circuit board production system further includes a body 5 and a conveying mechanism 6, the conveying mechanism 6 being mounted on the body 5; The conveying mechanism 6 includes a profile 61, a motor 62, a drive pulley 63, a driven pulley 64, and a transmission belt 65. The profile 61 is fixedly connected to the machine body 5. The motor 62 is mounted on the profile 61. The output end of the motor 62 is connected to the drive pulley 63. The driven pulley 64 is rotatably connected to the profile 61. The transmission belt 65 passes around the drive pulley 63 and the driven pulley 64. The bearing base 43 is slidably connected to the profile 61. The transmission belt 65 is fixedly connected to the bearing base 43.

[0058] In operation, starting motor 62 causes its output to drive drive pulley 63, which in turn drives transmission belt 65. Driven pulley 64 rotates with transmission belt 65, which in turn drives the support base 43 to slide on profile 61, thus driving the support base 43. The support base 43, via first suction cup 45, drives the base 1, which in turn transports the circuit board. This initiates the next round of circuit board processing and assembly. Through this cyclical process, the circuit board production system achieves a complete automated production process from loading, processing, unloading to return, reducing manual operations and improving the continuity and stability of production cycles, thereby significantly improving overall production efficiency and system consistency.

[0059] The body 5 is equipped with a contact platform 7 that matches the base 1, which provides reverse support during the disassembly of the circuit board. When the circuit board is disassembled, the lifting device is controlled to move the base 1 downward. After the push rod 21 contacts the upper surface of the contact platform 7, pressure is applied downward. The push rod 21 generates an upward pushing force with the cooperation of the cavity 23, thereby causing the circuit board to gradually detach from the first surface 11 of the base 1.

[0060] Example 4 like Figures 15 to 17 As shown, this embodiment provides a circuit board production system, including a board loading machine 8 and a board unloading machine 9. The board loading machine 8 includes a first equipment body 81, a first circuit board transfer mechanism 82, and a first fixture lifting mechanism 83. The first circuit board transfer mechanism 82 and the first fixture lifting mechanism 83 are disposed within the first equipment body 81. The first circuit board transfer mechanism 82 is used to transfer the circuit board to the circuit board fixture of the first fixture lifting mechanism 83. The first fixture lifting mechanism 83 is used to carry the circuit board fixture and transfer the fixture. The board loading operation is completed by transferring the circuit board to the circuit board fixture through the first circuit board transfer mechanism 82. Then, the circuit board is transferred by the circuit board fixture for subsequent processing operations. When the circuit board is processed and unloading is required, the unloading machine 9 operates the unloading action of the circuit board.

[0061] The unloading machine 9 includes a second equipment body 91, a second circuit board transfer mechanism 92, and a second fixture lifting mechanism 93. Both the second circuit board transfer mechanism 92 and the second fixture lifting mechanism 93 are installed inside the second equipment body 91. Processed circuit boards are transported to the second equipment body 91 by existing conveying equipment until they reach the second fixture lifting mechanism 93. The second fixture lifting mechanism 93 drives the circuit board fixture to move up and down. During the unloading process, the second fixture lifting mechanism 93 moves the circuit board fixture downwards, causing the base 1 of the circuit board fixture to shift relative to the pusher 21. This causes the front end of the pusher 21 to extend beyond the first surface 11, thereby lifting the circuit board adhered to the fixing part 13. After completing the unloading action, the second circuit board transfer mechanism 92 then transfers the circuit board.

[0062] like Figure 10 As shown, this embodiment also includes a processing device 10 for processing the circuit board. The processing device is disposed between the upper board machine 8 and the lower board machine 9, and processes the circuit board during the process of transferring the circuit board through the circuit board fixture.

[0063] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
