Description

Technical Field

[0001] This utility model relates to the field of LCD screen production, and specifically refers to a fully automatic film peeling machine for LCD screen reflectors. Background Technology

[0002] The main function of the reflector in an LCD screen is to enhance the uniformity of light, and it usually works in conjunction with components such as the filter layer and the refractive plate.

[0003] Currently, after production, reflectors are coated with protective films on both sides to prevent scratches or the accumulation of dust and other debris. Before installation, these protective films must be removed to facilitate installation and use.

[0004] To improve the efficiency of automated production, many factories currently use film-peeling machines to remove the protective film. For example, the fully automatic liquid crystal display light guide plate film-peeling equipment disclosed in existing technology 202022378671.5 can simultaneously peel off the upper and lower protective films of the light guide plate through a double-sided film-peeling mechanism, but it has the following problems:

[0005] (1) In the prior art, the double-sided film-tearing mechanism only uses two sets of upper and lower adhesive rollers to peel the two protective films of the light guide plate. Due to the limited adhesion of the adhesive rollers, especially the longer the usage time, the lower the adhesion. In addition, for some protective films with adhesives, the reflector and the film have strong adhesion, which can easily lead to the protective film not being able to be peeled off from the reflector.

[0006] (2) In the prior art, the upper and lower adhesive rollers detach the protective films on the upper and lower surfaces of the light guide plate from the light guide plate during the horizontal movement of the light guide plate. The film tearing path is simple and difficult to deal with complex adhesion scenarios.

[0007] (3) In the prior art, after the double-sided film tearing mechanism tears the film, the torn protective film will be wrapped around the upper and lower sets of adhesive rollers. It is difficult to remove the protective film wrapped around the upper and lower sets of adhesive rollers during the reset by only using the two pneumatic grippers on the clamping mechanism. This can easily lead to the protective film being pulled tighter and tighter on the adhesive rollers and breaking, eventually requiring the machine to be stopped for manual handling.

[0008] (4) Although the existing separation and picking mechanism can hold the center of the light guide plate against the suction bracket and use the separation cylinder to drive the swing bracket to flip the four corners of the light guide plate upward, thus breaking the vacuum condition between two adjacent light guide plates; however, since the reflector is made of plastic and the reflector is stacked, it is easy to generate static electricity and stick together tightly. In addition, the reflector is relatively thin and soft overall. Even if the separation cylinder drives the swing bracket to flip the four corners of the light guide plate upward, it may not be possible to separate the reflector that is sticking together tightly under static electricity, resulting in the problem of multiple pieces being picked up by mistake.

[0009] (5) The existing technology has adopted a three-axis moving suspension and the separation material picking mechanism is equipped with a lifting material picking cylinder. However, the material bin also needs to be equipped with a lifting plate, push rod and lifting motor, which makes the overall structure more complicated and greatly increases the production cost. Utility Model Content

[0010] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fully automatic film peeling machine for LCD screen reflectors.

[0011] To achieve the above objectives, the technical solution adopted by this utility model is: a fully automatic film-removing machine for LCD screen reflectors, comprising a frame, a feeding bin, a feeding mechanism, a correction mechanism, a transfer robot, a film-removing mechanism, and a film-removing mechanism respectively arranged on the frame;

[0012] The feeding hopper is used to store stacked reflectors;

[0013] The feeding mechanism is used to take reflectors from the feeding bin. The feeding mechanism can separate multiple reflectors that are attracted together by electrostatics, ensuring that only one reflector is taken and placed in the calibration mechanism.

[0014] The correction mechanism is used to correct the position of the reflector;

[0015] The transfer robot is used to first send the corrected reflector from the correction mechanism to the film removal mechanism to remove the lower film, and then to the film removal mechanism to remove the upper film. It includes a robot arm and a suction cup assembly set at the drive end of the robot arm. The suction cup assembly includes a suction cup bracket and multiple vacuum suction cups evenly distributed at the bottom of the suction cup bracket.

[0016] The film-peeling mechanism includes a film-peeling suction cup with its suction port facing upwards to hold one corner of the reflector's lower film, a lower film gripper cylinder located next to the film-peeling suction cup, and a pressure block located at one corner of the suction cup support. The pressure block is used to press against one corner of the reflector film, making it easier for the film-peeling suction cup to hold the lower film at one corner. The film-peeling suction cup, with the assistance of a transfer robot, is used to tear open one corner of the reflector's lower film. The lower film gripper cylinder is used to clamp one corner of the lower film opening and, with the assistance of the transfer robot, completes the tearing of the lower film.

[0019] Preferably, the feeding mechanism includes an XYZ axis linear module mounted on the frame and located above the feeding bin and the calibration mechanism, a material picking component mounted on the drive end of the XYZ axis linear module, and a detection component mounted on the frame.

[0020] The material handling assembly includes a support plate, separation cylinders vertically arranged at the four corners of the support plate, a suction cup located below the support plate and on the drive end of the separation cylinders, a top rod vertically arranged at the bottom center of the support plate, and an antistatic ion fan arranged on one side of the support plate; a sensor is provided at the bottom of the top rod, which can feed back the position information of the reflector in the feeding bin to the control system;

[0021] The detection component is used to detect whether the material picking component has only picked up one reflector. If multiple reflectors are picked up, two sets of separation cylinders placed diagonally alternately extend and twist the reflectors, and an antistatic ion fan blows ion air to separate the reflectors that are adsorbed together, ensuring that the material picking component can only pick up one reflector at a time.

[0022] Preferably, the feeding bin is provided at least once, including a storage base and multiple limiting rods respectively vertically arranged around the storage base; the multiple limiting rods form a receiving cavity for placing the reflector; the top of the multiple limiting rods is provided with a brush for initially peeling off the reflectors that are adsorbed together.

[0023] Preferably, the multiple limiting rods can be adjusted in both length and width directions.

[0024] Preferably, the feeding bin further includes L-shaped support seats located on both sides of the storage seat, two horizontally placed slide rails for connecting the L-shaped support seats and the sides of the storage seat, a cover plate located at the outer end of the storage seat, and a handle located on the outer side of the cover plate.

[0025] Preferably, the calibration mechanism includes a calibration frame, an X-axis lead screw double nut assembly and a Y-axis lead screw double nut assembly arranged vertically and alternately within the calibration frame; each of the X-axis and Y-axis lead screw double nut assemblies includes a horizontally placed lead screw with opposite directions of rotation at both ends, nuts respectively disposed at both ends of the lead screw, a servo motor for driving the lead screw to rotate so that the two threads move closer or further apart, and an extension frame disposed on the nuts; the extension frame has a calibration column extending out from the top of the calibration frame for calibrating the position of the reflector; the plurality of calibration columns form a calibration area for accommodating the reflector.

[0026] Preferably, the frame is further provided with a moving platform for driving the correction mechanism to move in the direction of the transfer robot.

[0027] Preferably, it also includes a waste collection device; the waste collection device includes a lower membrane vacuum feeder and an upper membrane vacuum feeder;

[0028] The lower film vacuum feeder is installed inside the frame and located next to the lower film gripper cylinder; the film tearing mechanism also includes a film tearing bracket, a rotary cylinder installed on the film tearing bracket, and an extension cylinder installed at the drive end of the rotary cylinder; the lower film gripper cylinder is installed at the drive end of the extension cylinder.

[0029] The upper film vacuum feeder is installed inside the frame and located below the upper film gripper cylinder.

[0030] Preferably, an inspection mechanism and an online robotic arm are provided on the frame at the discharge end of the film-tearing mechanism;

[0031] The online robotic arm is used to take the reflector from the adsorption assembly, place it on the inspection mechanism for inspection, and send the qualified reflector to the assembly equipment of the next process.

[0032] The inspection agency is used to inspect whether the upper and lower films on both sides of the reflective film have been completely removed.

[0033] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0034] 1. This utility model adopts a step-by-step method of peeling off the lower and upper films. By using a cylinder in conjunction with a transfer robot, it can effectively peel off the highly adhesive film from the reflector. It has the advantages of high automation, high precision, and high reliability.

[0035] 2. In this utility model, the film-peeling mechanism first uses a pressure block to hold down one corner of the lower film, then the film-peeling suction cup pulls it open at an angle, and then the gripper cylinder gradually peels it off, avoiding the tearing problem caused by direct pulling; while in the film-peeling mechanism, the adsorption component rotates 30-45° and then moves horizontally to peel the film, optimizing the film-peeling angle and path, which can cope with complex adhesion scenarios and greatly improve the success rate of film peeling.

[0036] 3. The present invention solves the problem of electrostatic adsorption by the dual design of initial separation by the feeding bin brush and dynamic separation by the picking component. It can effectively separate multiple reflectors that are adsorbed together by electrostatics, greatly reduce the mis-picking rate and significantly improve reliability.

[0037] 4. In this utility model, waste film is automatically collected by a vacuum feeder. Specifically, the lower film vacuum feeder, combined with a rotary cylinder and an extension cylinder, collects the torn lower film, while the upper film vacuum feeder directly uses gravity and suction to collect the upper film. The waste film recycling rate is high, reducing manual intervention and environmental pollution.

[0038] 5. In this utility model, high-precision correction can be achieved before film tearing through the X / Y bidirectional lead screw double nut assembly in the correction mechanism, resulting in high positioning accuracy and significantly improved consistency of the film tearing edge. Furthermore, by setting up a moving platform, interference between the robotic arm and the feeding mechanism during material handling can be avoided.

[0039] 6. The feeding hopper in this utility model adopts a pull-out structure, which not only facilitates manual replenishment, but also keeps it away from the feeding mechanism to avoid danger. Attached Figure Description

[0057] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0058] Appendix Figure 1-8 The fully automatic film-removing machine for LCD screen reflectors described in this utility model includes a frame 1, a feeding bin 2, a feeding mechanism 3, a correction mechanism 4, a transfer robot 5, a film-removing mechanism 6, and a film-removing mechanism 7, all respectively disposed on the frame 1.

[0059] The feeding bin 2 is used to store stacked reflectors A;

[0060] The feeding mechanism 3 is used to take reflector A from the feeding bin 2. The feeding mechanism 3 can separate multiple reflectors A that are attracted together by electrostatics, ensuring that only one reflector A is taken out and placed in the correction mechanism 4.

[0061] The correction mechanism 4 is used to correct the position of the reflector A;

[0062] The transfer robot 5 is used to first send the corrected reflector A from the correction mechanism 4 to the film removal mechanism 6 to remove the lower film, and then to the film removal mechanism 7 to remove the upper film. It includes a robot arm 51 and a suction cup assembly 52 set at the drive end of the robot arm 51. The suction cup assembly 52 includes a suction cup bracket 521 and a plurality of vacuum suction cups 522 evenly distributed at the bottom of the suction cup bracket 521.

[0063] The film-peeling mechanism 6 includes a film-peeling suction cup 61 with its suction port facing upwards for holding a corner of the lower film of reflector A, a lower film gripper cylinder 62 disposed next to the film-peeling suction cup 61, and a pressure block 63 disposed at a corner of the suction cup bracket 521; the pressure block 63 is used to press against a corner of the film of reflector A, so that the film-peeling suction cup 61 can hold the corner of the lower film; the film-peeling suction cup 61 is used to tear a corner of the lower film of reflector A with the cooperation of the transfer robot 5; the lower film gripper cylinder 62 is used to clamp a corner of the opening of the lower film, and the lower film is completely peeled off with the cooperation of the transfer robot 5.

[0064] The film-peeling mechanism 7 includes a linear film assembly 71, a support plate 72 horizontally arranged on the driving end of the linear film assembly 71, an adsorption component 73 arranged on the support plate 72, a motor 74 vertically arranged on the support plate 72 for driving the adsorption component 73 to rotate horizontally, a crossbeam 75 arranged above the linear film assembly 71 and perpendicular to the linear film assembly 71, a lifting cylinder 76 vertically arranged on the crossbeam 75, and a film-peeling gripper cylinder 77 inclinedly arranged on the driving end of the lifting cylinder 76.

[0065] During operation: The operator stacks reflectors A in the feeding hopper 2, then starts the equipment. The feeding mechanism 3 removes reflectors A one by one from the feeding hopper 2 and places them into the calibration mechanism 4 for position calibration. The feeding mechanism 3 can separate multiple reflectors A that are electrostatically attracted together, ensuring that only one reflector A is placed into the calibration mechanism 4. Next, the transfer robot 5 uses the calibrated reflector A to first send it from the calibration mechanism 4 to the film removal mechanism 6 to remove the lower film, and then to the film removal mechanism 7 to remove the upper film. The specific film removal process is as follows:

[0066] Although both the upper and lower films protrude from one corner of the reflector A, the presence of the upper film prevents the lower film gripper cylinder 62 from directly gripping it. Instead, a small opening must first be made using the film-tearing suction cup 61, followed by gripping with the lower film gripper cylinder 62. The specific working principle is as follows: The robotic arm 51 drives the suction cup assembly 52 to position one corner of the reflector A film at the suction port of the film-tearing suction cup 61. Since a pressure block 63 is provided at one corner of the suction cup bracket 521, it can hold against one corner of the reflector A film, allowing the film-tearing suction cup 61 to grip one corner of the lower film. Then, the robotic arm 51 drives the suction cup assembly 52 to move the reflector A diagonally upwards, tearing a small opening in the lower film of the reflector A using the film-tearing suction cup 61. Finally, the lower film gripper cylinder 62 grips the torn opening in the lower film. At the corner, the robotic arm 51 continues to drive the suction cup assembly 52 to move the reflector A diagonally upward until the lower film is completely peeled off. Then, the robotic arm 51 drives the suction cup assembly 52 to send the reflector A with the lower film peeled off to the adsorption assembly 73, where it is adsorbed and fixed. Then, the motor 74 drives the adsorption assembly 73 to rotate horizontally by about 30-45 degrees, so that one corner of the reflector A is facing the upper film clamping cylinder 77. Then, the linear module drives the carrier plate 72 to move the reflector A to below the upper film clamping cylinder 77. The lifting cylinder 76 drives the upper film clamping cylinder 77 to descend, clamping one corner of the upper film of the reflector A. Then, the linear module continues to drive the carrier plate 72 to move the reflector A horizontally until the upper film is completely peeled off.

[0067] Furthermore, such as Figure 4 As shown, the pressure block 63 is mounted on one corner of the suction cup bracket 521 via an adjustment frame 64, which can adjust the height of the pressure block 63 and the distance between the pressure block 63 and the suction cup bracket 521, and is compatible with multiple sizes of reflectors A; specifically, the horizontal and vertical parts of the adjustment frame 64 are provided with elongated grooves 65, and the height of the pressure block 63 and the distance between the pressure block 63 and the suction cup bracket 521 can be adjusted by tightening and loosening the locking parts.

[0068] Furthermore, such as Figure 4 As shown, the adjustment frame 64 and the pressure block 63 are connected by a spring 66. When the thin film B of the reflector A comes into contact with the peeling film suction cup 61, it can play a buffering role to avoid damaging the peeling film suction cup 61.

[0069] Furthermore, such as Figure 9-10 As shown, the feeding mechanism 3 includes an XYZ axis linear module 31 mounted on the frame 1 and located above the feeding bin 2 and the calibration mechanism 4, a material picking component 32 mounted on the drive end of the XYZ axis linear module 31, and a detection component mounted on the frame 1 (not labeled in the figure).

[0070] The material handling assembly 32 includes a support plate 321, separation cylinders 322 vertically arranged at the four corners of the support plate 321, a suction cup 323 located below the support plate 321 and arranged on the driving end of the separation cylinders 322, a top rod 324 vertically arranged at the bottom center of the support plate 321, and an antistatic ion fan 325 arranged on one side of the support plate 321; a pressure sensor is provided at the bottom of the top rod 324, which can feed back the position information of the reflector A in the feeding bin 2 to the control system.

[0071] The detection component uses optical fiber to detect whether only one reflector A has been picked up by the material picking component 32. If multiple reflectors A have been picked up, two sets of separation cylinders 322 placed diagonally alternately extend, retract, and twist the reflectors A, while the antistatic ion fan 325 blows ion air to separate the reflectors A that are adsorbed together, ensuring that the material picking component 32 can only pick up one reflector A at a time.

[0072] The principle by which the material-picking component 32 separates the reflectors A that are adsorbed together is as follows: When the XYZ axis linear module 31 drives the material-picking component 32 to pick up the reflectors A from the feeding bin 2, the bottom of the push rod 324 first contacts the top reflector A. Since the head of the push rod 324 is equipped with a pressure sensor, the position information of the reflector A can be fed back to the control system. At this time, the bottom of the push rod 324 presses against the middle of the reflector A, and the four separation cylinders 322 drive the suction cups 323 to extend and pick up the four corners of the reflector A, and then send them to the detection component for inspection. If only one reflector A is picked up, it is directly sent to the correction mechanism 4 for position correction; otherwise, if multiple reflectors A are picked up, the two sets of separation cylinders 322 placed diagonally extend and retract alternately, causing the reflectors A to bend and deform. At the same time, the antistatic ion fan will continuously blow ion air on the sides of the multiple reflectors A. Through the neutralization of the static charge on the surface of the multiple reflectors A by ions, static electricity is eliminated until the reflectors A that are adsorbed together are separated.

[0073] Furthermore, such as Figure 2 As shown, a storage box 33 is provided on the frame 1 next to the detection component. When the material taking component 32 separates the reflectors A that are adsorbed together, it is located directly above the storage box 33. The separated reflectors A fall into the storage box 33 for collection.

[0074] Furthermore, such as Figure 11-12As shown, the calibration mechanism 4 includes a calibration frame 41, an X-axis lead screw double nut assembly 42 and a Y-axis lead screw double nut assembly 43 arranged vertically and alternately within the calibration frame 41; both the X-axis lead screw double nut assembly 42 and the Y-axis lead screw double nut assembly 43 include horizontally placed lead screws with opposite directions of rotation at both ends, nuts respectively disposed at both ends of the lead screws, a servo motor that drives the lead screws to rotate so that the two threads move closer or further apart, and an extension frame disposed on the nuts; the extension frame is vertically provided with calibration columns extending out from the top of the calibration frame 41 for calibrating the position of the reflector A; the plurality of calibration columns form a calibration area for accommodating the reflector A;

[0075] When the feeding mechanism 3 takes the reflector A from the feeding bin 2 one by one and places it in the correction area, the X-axis lead screw 421 in the X-axis lead screw double nut assembly 42 is driven to rotate by the X-axis servo motor 423. Since the two ends of the X-axis lead screw 421 rotate in opposite directions, they respectively drive the two ends of the X-axis nut 422 to bring the X-axis extension frame 424 closer to each other until the X-axis correction column 425 in the length direction contacts the edge of the film B at both ends of the reflector A, thereby realizing the position correction in the length direction.

[0076] The Y-axis lead screw double nut assembly 43 drives the Y-axis lead screw 431 to rotate through the Y-axis servo motor 433. Since the two ends of the Y-axis lead screw 431 rotate in opposite directions, they respectively drive the two Y-axis nuts 432 to move closer to each other on the Y-axis extension frame 434 until the Y-axis correction column 435 in the width direction contacts the edge of the film B on both sides of the reflector A, thereby realizing the position correction in the width direction.

[0077] Furthermore, such as Figure 11 As shown, the frame 1 is also provided with a moving platform 44 for driving the correction mechanism 4 to move in the direction of the transfer robot 5, so as to avoid interference between the transfer robot 5 and the feeding mechanism 3 when it takes material from the correction mechanism 4.

[0078] Furthermore, such as Figure 13 As shown, the feeding bin 2 includes a storage base 21 and multiple limiting rods 22 vertically arranged around the storage base 21; the multiple limiting rods 22 form a receiving cavity for placing the reflector A; the top of the multiple limiting rods 22 is provided with a brush 23 for initially peeling off the reflector A that is adsorbed together.

[0079] During operation: The staff places the reflector A in the receiving cavity, and it is limited by multiple limiting rods 22 on all sides; when the feeding mechanism 3 takes the reflector A out of the receiving cavity, the brush 23 on the top of the limiting rod 22 can initially separate the reflector A that is adsorbed together.

[0080] Furthermore, such as Figure 13-14As shown, the feeding bin 2 also includes L-shaped support seats 24 located on both sides of the storage seat 21, two horizontally placed slide rails 25 for connecting the L-shaped support seats 24 and the sides of the storage seat 21, a cover plate 26 located at the outer end of the storage seat 21, and a handle 27 located on the outer side of the cover plate 26. When one of the feeding bins 2 is short of material, the equipment will sound an alarm. At this time, the staff can pull out the storage seat 21 through the handle 27 to replenish the material. Since the storage seat 21 after being pulled out is far away from the working area of ​​the feeding mechanism 3, it can effectively avoid danger during replenishment and ensure high safety.

[0081] Furthermore, such as Figure 15 As shown, the multiple limiting rods 22 can be adjusted in both length and width directions to accommodate reflectors A of different sizes. The spacing between the limiting rods 22 can be adjusted via a screw double nut assembly or a long hole structure. In this embodiment, the spacing between the limiting rods 22 in the length direction is adjusted via a screw double nut assembly 28, wherein the adjusting handwheel 29 of the screw double nut assembly 28 extends into the cover plate 26 and is located below the handle 27, while the spacing between the limiting rods 22 in the width direction is manually adjusted via a long hole and bolts.

[0082] Furthermore, such as Figure 2 As shown, there are two feeding bins 2, which are placed side by side; when one is feeding, the other can be manually replenished, so as to achieve non-stop operation.

[0083] Furthermore, such as Figure 2 and Figure 5 As shown, it also includes a waste collection device; the waste collection device includes a lower membrane vacuum feeder 60 and an upper membrane vacuum feeder 70;

[0084] The lower film vacuum feeder 60 is installed inside the frame 1 and located next to the lower film gripper cylinder 62. The film tearing mechanism 6 also includes a film tearing bracket 67, a rotary cylinder 68 installed on the film tearing bracket 67, and an extension cylinder 69 installed at the drive end of the rotary cylinder 68. The lower film gripper cylinder 62 is installed at the drive end of the extension cylinder 69. After the lower film gripper cylinder 62 tears off the lower film, the extension cylinder 69 extends, and at the same time, the rotary cylinder 68 drives the lower film gripper to rotate to the side of the lower film vacuum feeder 60. After rotating to the correct position, the lower film gripper cylinder 62 releases the lower film, and the lower film vacuum feeder 60 generates suction to collect the lower film.

[0085] The upper film vacuum feeder 70 is installed inside the frame 1 and located below the upper film gripper cylinder 77. When the upper film gripper cylinder 77 tears off the upper film, it directly releases the upper film, and the upper film vacuum feeder 70 generates suction to collect the upper mold.

[0086] Furthermore, such as Figure 2As shown, an inspection mechanism 8 and an online robotic arm 9 are provided on the frame 1 at the discharge end of the film-tearing mechanism 7;

[0087] The online robotic arm 9 is used to take the reflector A from the adsorption component 73, place it on the inspection mechanism 8 for inspection, and send the qualified reflector A to the assembly equipment of the next process, realizing online operation, reducing manual intervention, and achieving full automation;

[0088] The inspection mechanism 8 visually inspects whether the upper and lower films on both sides of the reflective film have been completely removed, significantly improving reliability.

[0089] Furthermore, such as Figure 11 As shown, the bottom of the receiving cavity and the correction area, as well as the adsorption assembly 73, are all equipped with sensing sensors 45 for detecting the presence or absence of reflector A. When the sensing sensor in the receiving cavity detects the absence of reflector A, it issues a material shortage alarm to remind the staff to replenish the material. When the sensing sensor 45 in the correction area detects the presence of reflector A, it initiates position correction. If the sensing sensor on the adsorption assembly 73 detects the presence of reflector A, it performs the film-peeling action.

[0090] Furthermore, such as Figure 1 As shown, a protective cover 10 is also provided on the frame 1; the feeding bin 2, the loading mechanism 3, the correction mechanism 4, the transfer robot 5, the film-peeling mechanism 6, the film-peeling mechanism 7, and the online robot 9 are all located inside the protective cover 10, wherein the feeding bin 2 and the online robot 9 are located at opposite ends of the protective cover 10, and the protective cover 10 at one end of the online robot 9 has an open structure, which facilitates docking with the assembly equipment of the next process.

[0091] Furthermore, such as Figure 1 As shown, the protective cover 10 has an openable protective window 11 on its side for easy daily maintenance and repair.

[0092] Furthermore, the protective window 11 is made of transparent acrylic sheet, which allows staff to monitor the internal working conditions in real time.

[0093] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
