Looped vertical lift continuous electroplating nickel-gold wire

Abstract

This utility model relates to a circular vertical lifting continuous electroplating nickel-gold wire, comprising several clamps for holding PCB boards, a symmetrically arranged rotating mechanism one and a rotating mechanism two, with vertically lifting electroplating tweezers and vertically lifting electroplating gold wires arranged facing each other between rotating mechanism one and rotating mechanism two. The clamps move cyclically along the vertically lifting electroplating tweezers, rotating mechanism two, vertically lifting electroplating gold wires, and rotating mechanism one in a circular trajectory. The advantages are: the cyclic movement of the clamps along the circular trajectory ensures a consistent electroplating path for each OCB board, avoiding differences in electroplating paths affecting electroplating quality; the cyclic movement of the clamps reduces the need for transfer equipment and channels, reducing the footprint of the electroplating equipment; and the vertical lifting method allows the PCB board to be directly inserted into the lower gold bath, eliminating the need for the upper gold bath in traditional vertical continuous electroplating lines, reducing the volume of the gold bath and the initial one-time investment cost for the enterprise.

Description

Technical Field

[0001] This utility model relates to the field of nickel-gold electroplating equipment, and in particular to a ring-shaped vertical lifting continuous nickel-gold electroplating line. Background Technology

[0002] The common process for electroplating nickel-gold plating consists of 16 steps, including pre- and post-treatment, nickel plating, and gold plating. Due to the numerous steps and speed limitations of gantry electroplating, it can only produce two flybars every 5 minutes. Assuming each flybar produces 3 plates, a total of 6 plates are produced, meaning it takes 50 seconds to produce one plate. Furthermore, the different processing paths for each product affect the plating quality.

[0003] When using existing vertical continuous electroplating lines to produce nickel-gold plating, an upper gold plating tank and a lower gold plating tank are required, and inlet and outlet ports at both ends are needed for tank solution circulation. This results in excessively large gold plating tank volumes and a large initial investment that is difficult for companies to bear. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems in the existing technology and to provide a ring-shaped vertical lifting continuous electroplating nickel-gold wire.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0021] Among them, lifting mechanism one, lifting mechanism two, lifting mechanism three, lifting mechanism four, and lifting mechanism five are all belt lifting mechanisms. Each belt lifting mechanism includes a lifting motor, a rotating shaft, two bearing seats, and a lifting frame. The power output shaft of the lifting motor is connected to one end of the rotating shaft through a coupling. The two ends of the rotating shaft are respectively installed in the bearing seats.

A fixed square tube two is installed on one side of the lifting frame. A clamp rail two is installed on the side of the fixed square tube two away from the lifting frame. Two sets of guide wheel groups are installed on the other side of the lifting frame. Each set of guide wheel groups includes four guide wheels one arranged in a rectangular array.

The push transmission chain meshes with the driving sprocket and the driven sprocket. Both ends of the push transmission chain are connected to the push frame. A transition plate is installed on one side of the lower part of the push frame. A push block is hinged to the lower part of the transition plate. When the push block is in a natural hanging state due to its own weight, the push block is tilted at 45° and the top of the push block abuts against the bottom of the push frame. Two parallel guide wheels are installed on the T-shaped rod. The upper part of the push frame is sandwiched between the two guide wheels.

[0059] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0060] like Figure 1 , Figure 2 , Figure 18As shown, a ring-shaped vertical lifting continuous electroplating nickel-gold wire includes several clamps 200 for holding a PCB board 100, a symmetrically arranged rotating mechanism 300 and a rotating mechanism 400, and vertical lifting electroplating tweezers 500 and vertical lifting electroplating gold wire 600 arranged opposite to each other between the rotating mechanism 300 and the rotating mechanism 400. The clamps 200 move cyclically along the vertical lifting electroplating tweezers 500, the rotating mechanism 400, the vertical lifting electroplating gold wire 600, and the rotating mechanism 300 according to a ring trajectory.

[0061] like Figure 1 , Figure 14 , Figure 17 As shown, the vertical lifting electroplating tweezers line 500 includes a row of mounting frames 501. On the mounting frames 501, a storage fixture 502, a lifting mechanism 503, a nickel bath 504, and a second lifting mechanism 505 are sequentially mounted from the rotating mechanism 300 towards the rotating mechanism 400. Above the storage fixture 502, a pushing mechanism 506 is mounted on the mounting frame 501 for moving the clamp 200 from the rotating mechanism 300 onto the storage fixture 502. Below the storage fixture 502, an opening mechanism 507 for opening the clamp and a robot 514 for loading PCB boards are mounted on the mounting frame 501. Below the lifting mechanism 503, a... Multiple micro-etching tanks 508 and multiple pickling tanks 509 are provided. A second pushing mechanism 510 for pushing the clamps on the storage rack 502 to the lifting mechanism 503 is installed on the mounting frame 501 below the lifting mechanism 503. A third pushing mechanism 511 for pushing the clamps 200 on the lifting mechanism 503 to the clamp chain conveying mechanism 7 of the nickel tank 504, a fourth pushing mechanism 512 for pushing the clamps 200 on the clamp chain conveying mechanism 7 of the nickel tank 504 to the lifting mechanism 505, and a fifth pushing mechanism 513 for pushing the clamps 200 on the lifting mechanism 505 to the rotating mechanism 400 are provided on the mounting frame 501 above the nickel tank 504.

[0062] like Figure 2 , Figure 15 , Figure 16 , Figure 17As shown, the vertical lifting electroplating gold wire 600 includes a row of mounting brackets 2 601. On the mounting brackets 2 601, a lifting mechanism 3 602, a storage fixture 2 603, a lifting mechanism 4 604, a gold tank lower slot 605, a lifting mechanism 5 606, and a storage fixture 3 607 are sequentially mounted from the rotating mechanism 2 400 towards the rotating mechanism 1 300. The mounting brackets 2 601 below the lifting mechanism 3 602 are equipped with clamps 200 for pushing the rotating mechanism 2 400 onto the lifting mechanism 3 602 and for pushing the clamps 200 on the lifting mechanism 3 602. The storage rack 2603 is equipped with a pushing mechanism 608, and the mounting frame 2601 below the lifting mechanism 3 is also equipped with multiple water washing tanks 609. The mounting frame 2601 below the storage rack 2603 is equipped with an opening mechanism 2610 for opening the clamp 200 and a robot 2611 for loading and unloading PCB boards. The mounting frame 2601 below the lifting mechanism 4 is equipped with a pushing mechanism 7 612 for pushing the clamp 200 on the storage rack 2603 onto the lifting mechanism 4 604. The mounting frame 2601 below the lifting mechanism 4 604 is equipped with a mounting mechanism 7 612 for pushing the clamp 200 on the storage rack 2603 onto the lifting mechanism 4 604. Multiple prepreg tanks 613 are installed on mounting frame 2 601. Above the lower gold tank 605, mounting frame 2 601 is equipped with a pushing mechanism 8 614 for moving the clamp 200 from lifting mechanism 4 604 to the lower gold tank 605, and a pushing mechanism 9 615 for moving the clamp 200 from the clamp chain conveying mechanism 7 to lifting mechanism 5 606. Below lifting mechanism 5 606, mounting frame 2 601 is equipped with a mechanism for moving the clamp 200 from lifting mechanism 5 606 to... The storage rack 3 607 has a pushing mechanism 10 616, and the mounting frame 2 601 below the lifting mechanism 5 606 is also equipped with multiple recycling tanks 617 and a hot water washing tank 618. The mounting frame 2 601 above the storage rack 3 607 is equipped with a pushing mechanism 11 619 for pushing the clamp 200 on the storage rack 3 607 to the rotating mechanism 1 300. The mounting frame 2 601 below the storage rack 3 607 is equipped with a drying tank 620, an opening mechanism 3 621 for opening the clamp, and a robot 3 622 for unloading PCB boards.

[0063] like Figure 1 , Figure 2 , Figure 18 The workflow shown is as follows:

[0064] The clamp is suspended from position one on the storage rack. The clamping mechanism one opens the clamp, and the robot picks up the PCB board and places it in the opened clamp. The clamping mechanism one then releases the opened clamp, allowing the movable clamping plate to engage with the fixed clamping plate to clamp the PCB board. The pushing mechanism two moves the clamp from storage rack one to lifting mechanism one. Lifting mechanism one inserts the clamp and the clamped PCB board into the first micro-etching groove for the first micro-etching, then lifts it up. The pushing mechanism two moves the clamp forward one groove position. Lifting mechanism one again inserts the clamp and the clamped PCB board into the second micro-etching groove for the second micro-etching, then lifts it up. This cycle continues until the clamp and the clamped PCB board have completed three micro-etching processes and two acid pickling processes. Lifting mechanism one moves the clamp and the PCB board into the tweezers cylinder inlet position. The pushing mechanism three moves the clamp from lifting mechanism one onto the clamp chain conveyor mechanism of the tweezers cylinder. Driven by the clamp chain conveyor mechanism of the tweezers cylinder, the clamp... The clamp and the PCB board being clamped move along the length of the clamp cylinder for electroplating. When the clamp and the PCB board reach the outlet of the clamp cylinder, the second lifting mechanism lowers to the outlet of the clamp cylinder. The fourth pushing mechanism pushes the clamp on the clamp chain conveyor mechanism of the clamp cylinder onto the second lifting mechanism. The second lifting mechanism raises the clamp. The fifth pushing mechanism pushes the clamp on the second lifting mechanism onto the second rotating mechanism. The second rotating mechanism rotates and conveys the clamp and the PCB board to the position connected with the third lifting mechanism. The sixth pushing mechanism pushes the clamp on the second rotating mechanism onto the third lifting mechanism. The third lifting mechanism and the sixth pushing mechanism work together to make the clamp and the PCB board undergo three water washes in sequence. Then the sixth pushing mechanism pushes the clamp on the third lifting mechanism onto the second storage rack. The seventh pushing mechanism pushes the clamp on the second storage rack onto the fourth lifting mechanism. The seventh pushing mechanism and the fourth lifting mechanism work together to make the clamp and the PCB board undergo three pre-immersion treatments in sequence.Then, lifting mechanism four lowers the clamp and the clamped PCB board to the gold plating tank inlet. Pushing mechanism eight moves the clamp on lifting mechanism four onto the clamp chain conveyor mechanism in the lower gold plating tank. Driven by the clamp chain conveyor mechanism in the lower gold plating tank, the clamp and the clamped PCB board move along the length of the lower gold plating tank for electroplating. When the clamp and the clamped PCB board reach the gold plating tank outlet, lifting mechanism five lowers it to the outlet. Pushing mechanism nine moves the clamp on the clamp chain conveyor mechanism in the lower gold plating tank onto lifting mechanism five. Lifting mechanism five and pushing mechanism ten work together to allow the clamp and the clamped PCB board to undergo three recycling processes and one hot water wash process sequentially. Then, pushing mechanism... The lifting mechanism 5 pushes the clamp onto the storage holder 3. A blower installed in the drying trough dries the PCB board, causing water droplets to fall into the drying trough. After drying, the clamp and the clamped PCB board are pushed above the robot 3. The robot 3 then picks up the PCB board. The clamping mechanism 3 opens the clamp, and the robot 3 removes the PCB board from the clamp. The clamping mechanism 3 releases the clamp, and the lower part of the movable clamping plate fits tightly against the lower part of the fixed clamping plate. The pushing mechanism 11 pushes the clamp onto the storage holder 3 onto the rotating mechanism 1. The rotating mechanism 1 drives the clamp to rotate to the position where it engages with the storage holder 1. The pushing mechanism then pushes the clamp onto the storage holder 1.

[0065] When this circular vertical lifting continuous nickel-gold plating wire is only used for nickel plating, the fixture holding the PCB board moves to the storage fixture two after completing the nickel plating. Robot two and the clamping mechanism two cooperate to remove the nickel-plated PCB board, and the empty fixture continues to move to the storage fixture one in a cycle.

[0066] When this circular vertical lifting continuous nickel-gold plating line is only used for gold plating, robot two and clamping mechanism two work together to load the PCB board onto the clamp suspended on storage fixture two, and then perform the gold plating operation until the clamp holding the PCB board moves to storage fixture three. Robot three and clamping mechanism three work together to remove the gold-plated PCB board, and the empty clamp continues to move cyclically to storage fixture two.

[0067] like Figure 1 , Figure 2 , Figure 3 As shown, storage fixture 1 (502), storage fixture 2 (603), and storage fixture 3 (607) are all fixed-height clamp storage fixtures 1. Each clamp storage fixture 1 includes a fixed square tube 11 and a long strip-shaped clamp rail 12, with the clamp rail 12 installed on one side of the fixed square tube 11. The sliding groove of the clamp 200 slides in conjunction with the clamp rail 12, allowing the clamp 200 to move along the clamp rail 12 under external force.

[0068] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, lifting mechanisms 1 (503), 2 (505), 3 (602), 4 (604), and 5 (606) are all belt-driven lifting mechanisms 2. Each belt-driven lifting mechanism 2 includes a lifting motor 21, a rotating shaft 22, two bearing seats 23, and a lifting frame 24. The power output shaft of the lifting motor 21 is connected to one end of the rotating shaft 22 via a coupling. Both ends of the rotating shaft 22 are respectively installed in the bearing seats 23. The bearing seats 23 are bolted to the top of the mounting bracket 1 (501) or the top of the mounting bracket 2 (601). Two pulleys 25 are installed on the rotating shaft 22, and a belt 26 is wound around each pulley 25. The bottom ends of the two belts 26 are installed on the lifting frame 24. A fixed square tube 27 is installed on one side of the lifting frame 24. A clamp rail 28 is installed on the side of the fixed square tube 27 away from the lifting frame 24. Two sets of guide wheel sets are installed on the other side of the lifting frame 24. Each set of guide wheel sets includes four guide wheels 29 arranged in a rectangular array. The groove of the clamp 200 slides into the clamp track 28, allowing the clamp 200 to move along the clamp track 28 under the action of external force.

[0069] When the lifting motor 21 rotates forward, it causes the pulley 25 to unwind the belt 26 wound around it, and the lifting frame 24 descends; when the lifting motor 21 rotates in reverse, it causes the pulley 25 to wind up the belt 26, and the lifting frame 24 rises.

[0070] like Figure 1 , Figure 2 , Figure 6 , Figure 7As shown, the following mechanisms are chain-type moving mechanisms 3: moving mechanism 1 (506), moving mechanism 2 (510), moving mechanism 3 (511), moving mechanism 4 (512), moving mechanism 5 (513), moving mechanism 6 (608), moving mechanism 7 (612), moving mechanism 8 (614), moving mechanism 9 (615), moving mechanism 10 (616), and moving mechanism 11 (619). Each chain-type moving mechanism 3 includes a moving motor 31, a driving sprocket 1 (32), a driven sprocket 1 (33), a moving transmission chain 34, a moving frame 35, and a T-shaped lifting rod 38. The driving sprocket 1 (32) is mounted on the power output of the moving motor 31. On the shaft, the pushing transmission chain 34 meshes with both the driving sprocket 32 ​​and the driven sprocket 33. Both ends of the pushing transmission chain 34 are connected to the pushing frame 35. A transition plate 36 is installed on one side of the lower part of the pushing frame 35. A pushing block 37 is hinged to the lower part of the transition plate 36. When the pushing block 37 is in a naturally drooping state due to its own weight, the pushing block 37 tilts at 45°, and its top end abuts against the bottom end of the pushing frame 35. Two parallel guide wheels 39 are installed on the T-shaped rod 38, and the upper part of the pushing frame 35 is sandwiched between the two guide wheels 39. Each set of chain-type pushing mechanisms 3 has at least two T-shaped rods 38, ensuring that the upper part of the pushing frame 35 is sandwiched between at least two pairs of guide wheels 39, thus guaranteeing that the pushing frame 35 can reciprocate in a straight line.

[0071] The moving frame 35 is a rectangular frame. The length of the moving frame 35 is adapted to the number of fixtures to be moved and the front and rear installation space. The number of moving blocks 37 set at the bottom of the moving frame 35 is adapted to the number of fixtures to be moved at the same time.

[0072] When the lower part of the push block 37 is aligned with the moving direction of the push frame 35, the lower part of the push block 37 abuts against the top of the contacting clamp 200, pushing the clamp 200 to move along the moving direction of the push frame 35; when the lower part of the push block 37 is aligned with the moving direction of the push frame 35, the lower part of the push block 37 contacts the clamp 200 and rotates upward, allowing the push block 37 to pass smoothly through the clamp 200.

[0073] When the pusher motor 31 rotates forward, it drives the drive sprocket 32 ​​to rotate forward, causing the pusher transmission chain 34 to move forward, thereby driving the pusher frame 35 to move forward, so that the pusher block 37 at the bottom of the pusher frame 35 pushes the fixture to be pushed to the target position; when the pusher motor 31 rotates in reverse, it drives the drive sprocket 32 ​​to rotate in reverse, causing the pusher transmission chain 34 to move in reverse, thereby driving the pusher frame 35 to move in reverse, so that the pusher frame 35 moves towards the fixture 200 to be pushed.

[0074] like Figure 1 , Figure 2 , Figure 8 , Figure 9As shown, both rotating mechanism 300 and rotating mechanism 400 are reciprocating rotating mechanisms 4. The reciprocating rotating mechanism 4 includes a mounting frame 41, a rotary motor 42, and a rotating rod 43. The rotary motor 42 is mounted on the top of the mounting frame 41. The head of the rotating rod 43 is mounted on the power output shaft of the rotary motor 42, and the rotating rod 43 is perpendicular to the power output shaft of the rotary motor 42. A fixed square tube 44 is mounted at the tail end of the rotating rod 43. A clamping rail 45 is mounted on the side of the fixed square tube 44 away from the rotating rod 43. A roller 46 is mounted at the bottom end of the fixed square tube 44, and the roller 46 rolls along the semi-circular guide rail 47 at the top of the mounting frame 41. The groove of the clamp 200 slides in conjunction with the clamping rail 45, allowing the clamp 200 to move along the clamping rail 45 under external force.

[0075] When the rotary motor 42 rotates in the forward direction, it drives the rotary rod 43 to rotate from the initial position to the target position, thereby causing the clamp track 3 45 with the suspended clamp to rotate from the initial position to the target position; when the rotary motor 42 rotates in the reverse direction, it drives the rotary rod 43 to rotate from the target position to the initial position, thereby causing the clamp track 3 45 without the suspended clamp to rotate from the target position to the initial position.

[0076] like Figure 1 , Figure 2 , Figure 10 As shown, clamping mechanism 1 507, clamping mechanism 2 610, and clamping mechanism 3 621 are all pneumatic clamping mechanisms 5. The pneumatic clamping mechanism 5 includes an L-shaped bracket 51, a telescopic cylinder 52, a right-angled triangular pressure plate 53, and a pressure wheel 54. The L-shaped bracket 51 is hinged to the tail of the telescopic cylinder 52 and the acute angle of the pressure plate 53, respectively. The piston rod end of the telescopic cylinder 52 is hinged to the right angle of the pressure plate 53. The pressure wheel 54 is rotatably mounted on the acute angle of the pressure plate 53.

[0077] The extension of the telescopic cylinder 52 causes the pressure plate 53 to rotate in the forward direction, causing the pressure roller 54 to press against the upper part of the movable clamping plate 203 of the fixture 200. This causes the lower part of the movable clamping plate 203 of the fixture 200 to move away from the fixed clamping plate 204 of the fixture 200, opening the lower part of the movable clamping plate 203 of the fixture 200 with the lower part of the fixed clamping plate 204 of the fixture to release the PCB board or wait for the PCB board to be loaded. The retraction of the telescopic cylinder 52 causes the pressure plate 53 to rotate in the reverse direction, causing the pressure roller 54 to separate from the upper part of the movable clamping plate 203 of the fixture 200. This causes the lower part of the movable clamping plate 203 of the fixture 200 to move closer to the fixed clamping plate 204 of the fixture 200, thereby cooperating with the lower part of the movable clamping plate 203 of the fixture 200 to clamp the PCB board, or clamping the lower part of the movable clamping plate 203 of the fixture 200 with the lower part of the fixed clamping plate 204 of the fixture 200.

[0078] like Figure 1 , Figure 2 , Figure 11 , Figure 12 , Figure 13 As shown, Robot 1 (514), Robot 2 (611), and Robot 3 (622) are all suction-type robots (6). Each suction-type robot (6) includes a six-axis robotic arm (61) and a vacuum suction cup (62). The vacuum suction cup (62) is mounted on the connecting flange of the sixth axis of the six-axis robotic arm (61). The vacuum suction cup (62) contains four cavities arranged in a rectangular array. The back of the vacuum suction cup (62) has four suction ports (63) that communicate with the four cavities respectively. The front of the vacuum suction cup (62) has four sets of suction holes (64) that communicate with the four vacuum cavities respectively. A proximity switch (65) for detecting the distance between the vacuum suction cup (62) and the PCB board (100) is installed in the center of the top of the vacuum suction cup (62). The six-axis robotic arm (61) is connected to a robotic arm controller via a cable, and the proximity switch is also connected to the robotic arm controller via a cable. In this embodiment, a FANUC Robot M-10iD / 12 six-axis robotic arm and an R-30iB Mate Plus robotic arm controller are used.

[0079] like Figure 1 , Figure 2 , Figure 17 As shown, the clamp chain conveying mechanism 7 includes a conveying motor 71, a second driving sprocket 72, a second driven sprocket 73, a third driven sprocket 74, a fourth driven sprocket 75, a drive chain 76, a conveying chain 77, a fourth fixed square tube 78, and a fourth clamp track 79. The second driving sprocket 72 is mounted on the power output shaft of the conveying motor 71. The second driven sprocket 73 and the third driven sprocket 74 are mounted on the same gear shaft. The drive chain 76 meshes with both the second driving sprocket 72 and the second driven sprocket 73. The conveying chain 77 meshes with both the third driven sprocket 74 and the fourth driven sprocket 75. The fourth fixed square tube 78 is located on one side of the conveying chain 77 and is parallel to the conveying chain 77. When the clamp 200 is pushed onto the chain conveyor mechanism 7, the slide groove 201 on the clamp 200 slides into the clamp track 79, the driven sprocket 202 of the clamp 200 meshes with the conveyor chain 77, and the conveyor motor 71 works by cooperating with the drive sprocket 72, driven sprocket 73, driven sprocket 74, driven sprocket 75, and drive chain 76 to make the conveyor chain 77 drive the clamp to move along the clamp track 79, thereby realizing the movement of the clamp.

[0080] The micro-etching tank 508, pickling tank 509, water washing tank 609, pre-immersion tank 613, recovery tank 617, and hot water washing tank 618 are all rectangular box-shaped tanks with open tops, and each tank contains a corresponding solution.

[0081] The drying tray 620 is a rectangular box-shaped tray with a hair dryer installed inside.

[0082] The width of the nickel and gold baths is 350 mm.

[0083] Mounting bracket 1 (501), mounting bracket 2 (601), and mounting bracket 3 (41) are all assembled from steel pipes and steel plates by welding or fasteners.

[0084] The lifting motor 21, the pushing motor 31, the rotating motor 42, and the conveying motor 71 are all variable frequency motors, each connected to a frequency converter via a cable. Each frequency converter controls the operation of one variable frequency motor, including controlling the rotation direction and speed of the variable frequency motor. The frequency converters are connected to the factory's industrial control computer via cables, and the factory's industrial control computer sends control commands for each variable frequency motor to each frequency converter.

[0085] The factory's industrial control computer is also connected to each robotic arm controller via cables, enabling communication between the industrial control computer and each robotic arm controller.

[0086] The fixture moves cyclically along the vertical lifting electroplating tweezers line, the second rotating mechanism, the vertical lifting gold plating line, and the first rotating mechanism, ensuring a consistent electroplating path for each OCB board and preventing differences in plating paths from affecting plating quality. The fixture's cyclical movement reduces the need for transfer equipment and channels, thus reducing the footprint of the electroplating equipment. The vertical lifting method allows the PCB board to be directly inserted into the lower gold plating tank, eliminating the need for the upper gold plating tank in traditional vertical continuous electroplating lines. Furthermore, the width of the lower gold plating tank is reduced to 350mm, decreasing the volume of the gold plating tank and the initial one-time investment cost for the enterprise.

[0087] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
