Description

Technical Field

[0001] This utility model relates to the field of mechanical automation technology, specifically to a graphite boat gripping device and a fully automatic graphite boat calibration machine. Background Technology

[0002] A graphite boat is a carrier used to support photovoltaic cells. Its structure consists of several graphite boat sheets fixed together by bolts. During use, the graphite boat operates in various environments, and different graphite boat sheets experience different internal stresses. These internal stresses cause varying degrees of loosening and deformation. Therefore, after a period of use, the graphite boat needs to be reassembled using a calibration machine to align the sheets. During the calibration process, the configuration of the gripping device determines the accuracy and efficiency of the calibration.

[0003] Existing graphite boat calibration machines typically use pneumatic cylinders to open and close the grippers. Pneumatic cylinders, as common linear motion actuators, offer advantages such as simple structure and fast response. However, this method has limitations, especially in applications requiring large stroke adjustments. Due to the limited stroke of the cylinder, it's difficult to meet the gripping needs of graphite boats of various sizes, particularly when the boat dimensions vary significantly; pneumatic grippers often cannot accommodate different sizes. Furthermore, the limited adjustment range of the cylinder makes precise gripping position control difficult, resulting in insufficient stability and accuracy during the gripping process.

[0067] The specific embodiments of this utility model will be further described below with reference to Figures 1 to 16. The following embodiments are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0068] In semiconductor manufacturing, photovoltaic industry, and other fields, graphite boats serve as an important support tool, widely used in crystal growth, heat treatment, and other processes. Graphite boats come in various sizes, and different sizes may be required at different stages of the process. Therefore, the gripping device of a graphite boat calibration machine needs to have good compatibility and flexibility to accommodate the gripping needs of graphite boats of various sizes.

[0069] As shown in Figure 1(b), the existing gripping assembly 157 grips the graphite boat by being driven by a cylinder. The cylinder's stroke is limited, making it difficult to meet the gripping requirements of graphite boats of various sizes. Especially when the size of the graphite boat varies significantly, the cylinder-driven gripping device often cannot be compatible with graphite boats of different sizes. Therefore, Embodiment 1 below proposes a technical solution that can solve the above-mentioned technical problems.

[0070] Example 1

[0071] As shown in Figure 1(a), this utility model proposes a gripping device for a graphite boat, specifically including a support arm 1, a first clamping member 2, a second clamping member 3, and a belt drive assembly 7. The support arm 1 is provided with a first slide rail 101 along its length. Both the first clamping member 2 and the second clamping member 3 have a locking portion 4, a supporting portion 5, and a hooking portion 6. The first clamping member 2 and the second clamping member 3 are located at both ends of the support arm 1, and the locking portions 4 of the first clamping member 2 and the second clamping member 3 are slidably mounted on the first slide rail 101. The supporting portions 5 of the first clamping member 2 and the second clamping member 3 are used to support the boat's feet. The belt drive assembly 7 is deployed along the length of the support arm 1. The hooking portion 6 of the first clamping member 2 is connected to a first side of the belt, and the hooking portion 6 of the second clamping member 3 is connected to a second side of the belt. The belt drive assembly is used to drive the hooking portions of the first clamping member 2 and the second clamping member 3 to move relative to each other along the length direction. The first side of the belt is the upper belt, and the second side of the belt is the lower belt. The first clamping member 2 and the second clamping member 3 are slidably disposed at both ends of the first slide rail 101 of the support arm 1 via their locking parts 4, and are in their initial positions. At this time, the supporting parts 5 of the first clamping member 2 and the second clamping member 3 are both in an idle state, ready to support the hull of the graphite boat.

[0072] Belt drive assembly start-up: Start the belt drive assembly, and the belt drives the coupling part 6 of the first clamping member 2 and the second clamping member 3 to move along the length of the support arm 1. During this process, the belt acts as the transmission medium, ensuring that the first clamping member 2 and the second clamping member 3 can move smoothly and accurately to both sides of the graphite boat.

[0073] Supporting the graphite boat: When the first clamping member 2 and the second clamping member 3 move to the foot position of the graphite boat, the supporting part 5 contacts and supports the two feet of the graphite boat respectively. At this time, the first clamping member 2 and the second clamping member 3 firmly hold the graphite boat through the supporting part 5, preparing for subsequent handling or transfer work.

[0074] Moving the graphite boat: After supporting the graphite boat, the belt drive assembly 7 is activated again, driving the first clamping member 2 and the second clamping member 3 to move the graphite boat together to the target position. Throughout the process, the graphite boat remains stable and will not slip or tilt.

[0075] like Figure 2-3As shown, in one embodiment, the snap-fit ​​portion 4 located at the upper end of the first clamping member 2 and the second clamping member 3 includes: two fixed plates 401 spaced apart, and two first sliders 402 respectively provided on the inner sides of the two fixed plates 401 facing each other. When the first sliders 402 are provided on the inner sides of the fixed plates 401, the first slide rail 101 can be provided on the side of the support arm 1.

[0076] As a preferred embodiment, the first slide rail 101 can be disposed on the top surface of the support arm 1, and the first slider 402 in the corresponding snap-fit ​​part 4 can be disposed on the top of the fixing plate 401.

[0077] As a preferred embodiment, the first slide rail 101 can be disposed below the support arm 1, and the first slider 402 in the corresponding snap-fit ​​part 4 can be disposed at the bottom of the fixing plate 401.

[0078] In one embodiment, the support portion 5 located at the lower ends of the first clamping member 2 and the second clamping member 3 respectively includes: a clamping surface 501, and a support plate 502 disposed at the bottom end of the clamping surface 501. The support plate 502 is used to support the corners of the graphite boat during clamping; the support plates 502 of the first clamping member 2 and the second clamping member 3 are disposed opposite to each other. The provided support plate 502 enables the first clamping member 2 and the second clamping member 3 to be more stable during the clamping and gripping of the graphite boat.

[0079] like Figure 2-4 As shown, in one embodiment, in order to make the sliding transport process more stable and prevent deviation after the belt drive assembly drives the first clamping member and the second clamping member to grasp the graphite boat, two sections of first slide rail 101 are provided in the length direction of the support arm 1; the first clamping member 2 and the second clamping member 3 are respectively slidably mounted on the first slide rail 101 located at both ends of the support arm 1, and two stops are respectively provided at the two ends of the two sections of first slide rail that are close to each other.

[0080] In one embodiment, the first slide rail 101 is located on the side of the support arm 1 along its length.

[0081] In one embodiment, the mounting portion 6 located on the fixed plate 401 includes: a connecting plate 601, and a fastener 604 disposed on the connecting plate 603; the fastener 604 includes an upper pressure plate 6041 and a lower pressure plate 6042, the upper pressure plate 6041 and the lower pressure plate 6042 are fixed by nuts, and the upper pressure plate 6041 and the lower pressure plate 6042 cooperate with each other to clamp the belt.

[0082] As a preferred embodiment, the connecting part can overlap the two ends of the single belt, so that the first clamping member and the second clamping member can be synchronously aligned and slidably clamped.

[0083] As a preferred embodiment, the connecting part can be sleeved on both ends of the single belt, so that the first clamping member and the second clamping member can be synchronously aligned and slidably clamped.

[0084] As a preferred embodiment, the attachment can be mounted on two belts, and the first clamping member and the second clamping member can be controlled by the two belts to perform synchronous centering and sliding clamping.

[0085] like Figure 4 As shown, in one embodiment, the belt drive assembly 7 includes: a first motor 701, a drive pulley 702, and a driven pulley 703; the drive shaft of the first motor 701 is horizontally arranged, the first side of the belt is the upper belt, and the second side of the belt is the lower belt; the first motor 701 is disposed on one side of the support arm 1; the drive pulley 702 is drively connected to the drive shaft of the first motor 701; the driven pulley 703 is disposed on the other side of the support arm 1, and the driven pulley 703 is drively connected to the drive pulley 702 via the belt. The first motor and the belt cooperate with each other, featuring smooth transmission, low noise, high positioning accuracy, and a large stroke range. Through precise control of the motor, the positions of the first and second clamping members can be precisely adjusted, while the belt drive can meet the requirements of a large stroke, thus being compatible with the gripping of graphite boats of various specifications.

[0086] In one embodiment, the first motor 701 is mounted on one side of the support arm 1 via a motor fixing plate 8; the driven wheel 703 is mounted on the other side of the support arm 1 via a bearing fixing plate 9, and the driven wheel 703 is rotatably connected to the bearing fixing plate 9.

[0087] In this embodiment, the precise control of the first motor in the belt drive assembly enables precise adjustment of the positions of the first and second clamping components. At the same time, the synchronous belt drive in the belt drive assembly can meet the requirements of large stroke, thereby being compatible with the gripping of graphite boats of various specifications, significantly improving production efficiency and equipment versatility.

[0088] Example 2

[0089] like Figure 5 As shown in Figure 16, this utility model proposes a graphite boat calibration machine, including a chassis 10. Inside the chassis 10, from right to left, a loading and unloading device 11, a first buffer device 12, a tension correction device 13, and a detection device 14 are arranged sequentially. A conveying device 15 is arranged across the loading and unloading device 11, the first buffer device 12, the tension correction device 13, and the detection device 14. The conveying device 15 uses the gripping device in Embodiment 1.

[0090] To elaborate further, the loading and unloading device 11 loads the graphite boat into the first buffer device 12. Then, the conveying device 15 removes the graphite boat from the first buffer device 12 and places it into the tension correction device 13. The tension correction device 13 loosens the bolts of the graphite boat to loosen the sheet inside the graphite boat, then corrects and aligns the sheet, and then tightens the screws to complete the calibration. The conveying device 15 then conveys the graphite boat to the detection device 14 for detection. After the detection is completed, the conveying device 15 conveys the graphite boat to the second buffer device 16 for temporary storage, then conveys it to the first buffer device 12, and then sends it out by the loading and unloading device 11, completing the automated calibration of the graphite boat.

[0091] In one embodiment, the loading and unloading device 11 includes two symmetrical support seats 1101. A guide slide plate 1102 is fixedly installed on the opposite side of the two support seats 1101. A first servo motor 1103 and a first pulley assembly 1105 are arranged on the side of the guide slide plate 1102. The first servo motor 1103 drives and connects to the first pulley assembly 1105. A slide block 1104 is slidably installed on the guide slide plate 1102. The slide block 1104 is fixedly connected to the belt of the first pulley assembly 1105. The slide block 1104 is used to support the graphite boat. After sliding, the slide block 1104 docks with the buffer bracket of the first buffer device 12. The first servo motor 1103 drives the first pulley assembly 1105 to move the slide block 1104, sending the graphite boat to the first buffer device 12 or removing the calibrated graphite boat from the first buffer device 12.

[0092] The first buffer device 12 is mainly composed of several support frames set on the lifting structure. The support frames are lifted and lowered by the lifting structure, and the graphite boats are stacked up and down to achieve buffering.

[0093] like Figure 9-12 As shown, the tension adjustment device 13 includes an X-axis dual-rail servo moving module 131, an adjustment component 132 is arranged between the X-axis dual-rail servo moving modules 131, the X-axis dual-rail servo moving modules 131 drive and connect two first gantry moving trusses 133, a fourth Z-axis servo module 134 is symmetrically arranged on each first gantry moving truss 133, a first Y-axis servo module 135 is driven and arranged on the fourth Z-axis servo module 134, and the first Y-axis servo module 135 drives and connects to a bolt tensioning mechanism 136;

[0094] The graphite boat is transported to the adjustment assembly 132 by the handling device 15. The X-axis dual-rail servo moving module 131 drives the first gantry moving truss 133 to move along the X-axis. The fourth Z-axis servo module 134 drives the bolt tightening mechanism 136 to move along the Z-axis. The first Y-axis servo module 135 drives the bolt tightening mechanism 136 to move along the Y-axis. The bolt tightening mechanism 136 is mainly composed of a servo motor driving a screwdriver, so that the range of the bolt tightening mechanism 136 can cover the entire side of the graphite boat. The bolt tightening mechanism 136 loosens the bolts on the graphite boat, so that the sheets of the graphite boat are loosened.

[0095] After the adjustment component 132 is calibrated and adjusted, the bolt tightening mechanism 136 tightens and fixes all the bolts on the graphite boat.

[0096] The adjustment assembly 132 includes a Z-axis correction mechanism 1321, which is mounted on the first gantry moving truss 133. The Z-axis correction mechanism 1321 includes a lifting cylinder 13211, which drives the connecting pressure bar 13212 to descend, thereby flattening and aligning the graphite boat sheet in the Z-axis.

[0097] The adjustment assembly 132 also includes a fixed alignment seat 1322 and a sliding alignment seat 1323. The fixed alignment seat 1322 is used to fix one end of the graphite boat sheet to align it, and the sliding alignment seat 1323 moves to press the other end of the graphite boat sheet to achieve end alignment of the graphite boat sheet.

[0098] Adjustment component 132 also includes a support platform 1324 for supporting the graphite boat. Fixed baffles and movable side baffle brackets 1325 are respectively provided on both sides of the support platform 1324 for fixing the graphite boat from both sides.

[0099] Toothed support blocks 13241 are fixedly installed on the support platform 1324 to support the graphite boat sheet in sections, so that the sheet can cooperate with the pressure strip 13212 in a loose state to make the sheet spacing equal.

[0100] The support platform 1324 is slidably mounted on the second-layer platform plate 1328, and a third telescopic module 137 is provided between the support platform 1324 and the second-layer platform plate 1328. The third telescopic module 137 drives the support platform 1324 to move along the X-axis on the second-layer platform plate 1328, so that the graphite boat sheet on it abuts against the fixed alignment seat 1322 and the sliding alignment seat 1323 respectively, thereby aligning the two ends of the graphite boat sheet. With the movement of the sliding alignment seat 1323, the efficiency and flexibility of the alignment of the two ends of the graphite boat sheet are improved.

[0101] The second-layer platform plate 1328 is slidably mounted on the bottom surface of the chassis 1 via the bottom slide rail 1327. A moving platform 1326 is also slidably mounted on the bottom slide rail 1327. A side baffle bracket 1325 is fixedly mounted on the moving platform 1326. A first telescopic module 138 is provided between the moving platform 1326 and the second-layer platform plate 1328. The first telescopic module 138 drives the moving platform 1326 to move closer to or further away from the second-layer platform plate 1328, and adjusts the position of the side baffle bracket 1325 to adapt to graphite boats of different widths.

[0102] A second telescopic module 139 is provided between the second-layer platform plate 1328 and the bottom surface of the chassis 1. The second telescopic module 139 drives the second-layer platform plate 1328 to move along the Y-axis, so that the support platform 1324 moves along the Y-axis, so that the baffles and side support brackets 1325 on both sides no longer clamp the graphite boat, allowing the graphite boat to quickly enter and exit the support platform 1324.

[0103] The toothed support block mentioned above is fixedly installed on the support platform 1324 to support the graphite boat sheet in sections, so that the sheet can cooperate with the pressure strip 13212 in a loose state to make the sheet spacing equal; however, this fixed installation method is bound to the height, spacing and support surface shape of a single-specification graphite boat and cannot be compatible with graphite boats of multiple specifications.

[0104] Therefore, as Figure 13 As shown, to ensure compatibility with graphite boats of various specifications, the support teeth are designed with a lifting mechanism, specifically including a first support platform 1310 and a second support platform 1312. The first support platform 1310 is equipped with at least one first support tooth 1311; the second support platform 1312 is equipped with at least one second support tooth 1313. A drive assembly 1314 is used to drive at least one of the first and second support platforms 1310 and 1312 to lift or lower, so that the second support tooth 1313 is higher or lower than the first support tooth 1311. The first and second support teeth 1311 and 1313 support the graphite boat sheets and have different tooth spacings, ensuring compatibility with graphite boat specifications. The first and second support teeth can be lifted and lowered independently, allowing for precise adjustment of the support height and adaptability to graphite boat specifications of different thicknesses and sizes, thus improving the equipment's versatility.

[0105] Furthermore, the second support platform 1312 is disposed below the first support platform 1310; the first support platform 1312 is fixed with multiple rows of first support teeth 1311 at equal intervals along its length direction; the second support platform 1312 is fixed with multiple rows of second support teeth 1313 at equal intervals along its length direction.

[0106] Specifically, the first support platform 1312 has at least one first through slot corresponding to at least one second support tooth 1313; the first through slot is located between two adjacent rows of first support teeth 1311; each second support tooth 1313 passes through the corresponding at least one first through slot.

[0107] During operation, the drive assembly starts working, driving the first support tooth 101 on the first support platform and the second support tooth on the second support platform to rise and fall. In practical applications, only one support tooth needs to rise and fall, or both support teeth can rise and fall simultaneously but independently to achieve precise adjustment of the support position of the graphite boat sheet. As the support teeth rise and fall, the graphite boat sheet is supported at the appropriate height, thus meeting the requirements of a specific graphite boat specification. After adjustment, the drive assembly stops working, and the support teeth remain in the desired position. The adjustable-pitch support tooth frame design can accommodate graphite boats of different specifications without replacing the entire support system, thereby reducing production costs and replacement frequency.

[0108] The detection device 14 includes a slide rail assembly 141, which is equipped with a servo pulley structure. Two second gantry moving trusses 142 are slidably arranged on the slide rail assembly 141. The second gantry moving trusses 142 are driven by the servo pulley structure. A second Z-axis servo module 144 is fixedly installed on the two columns of each second gantry moving truss 142. A Y-axis camera assembly 145 is arranged on the second Z-axis servo module 144. The camera of the Y-axis camera assembly 145 performs Y-axis imaging detection on the graphite boat.

[0109] The upper end of the second gantry moving truss 142 is provided with a second Y-axis servo module 143, two third Z-axis servo modules 146 are provided on the second Y-axis servo module 143, and a Z-axis camera assembly 147 is provided on the third Z-axis servo module 146.

[0110] The second gantry moving truss 142 is moved along the X-axis by the slide rail assembly 141, and the Y-axis camera assembly 145 can move along the X-axis and Z-axis by the action of the second Z-axis servo module 144 to capture and detect the side of the graphite boat.

[0111] The cooperation of the second Y-axis servo module 143 and the third Z-axis servo module 146 enables the Z-axis camera assembly 1407 to move simultaneously along the X, Y, and Z axes, allowing for top-down shooting and detection of the graphite axis.

[0112] The results of the calibration of each graphite boat and each sheet were checked to see if they met the design standards.

[0113] The detection device 14 also includes an X-axis servo movement component 148, which is disposed between slide rail components 141. The X-axis servo movement component 148 includes an X-axis slide rail 1481, a second pulley assembly 1482, a support plate 1483, and a second servo motor 1484. The X-axis slide rail 1481 is fixedly disposed on the bottom surface of the housing 1. The second pulley assembly 1482 and the second servo motor 1484 are disposed on one side of the X-axis slide rail 1481. The second servo motor 1484 drives and connects to the second pulley assembly 1482. Two support plates 1483 are slidably disposed on the X-axis slide rail 1481. The two support plates 1483 are fixedly connected to the upper and lower parts of the belt of the second pulley assembly 1482, respectively. The support plates 1483 support the graphite boat.

[0114] The second pulley assembly 1482 moves the two support plates 1483 closer or further apart, adapting to graphite boats of different lengths and improving applicability.

[0115] As shown in Figures 1(b) and 16(a), the conveying device 15 includes a Y-axis belt-driven servo module 151. The Y-axis belt-driven servo module 151 includes a third servo motor 153, a third pulley assembly 154, and two tracks. The third servo motor 153 drives and connects to the third pulley assembly 154. A Y-axis moving seat 152 is slidably arranged on the track of the Y-axis belt-driven servo module 151. A Z-axis lifting rail mechanism 155 is arranged on the Y-axis moving seat 152. An X-axis support arm 156 is arranged at the lower end of the Z-axis lifting rail mechanism 155. A gripper assembly 157 is symmetrically arranged on the X-axis support arm 156.

[0116] The gripper assembly 157 is driven by a cylinder to grip the graphite boat, then lifted by the Z-axis lifting rail mechanism 155, and then moved by the Y-axis belt-driven servo module 151.

[0117] The working principle before the improvement: The external feeder sends the graphite boat to the loading and unloading device, which transports the graphite boat to the first buffer device. Then, the conveying device transports it to the tension correction device for tension correction. During the tension correction of the first graphite boat, the second graphite boat is sent to the first buffer device by the loading and unloading device for buffering. After the first graphite boat completes the correction, the conveying device transports the corrected first graphite boat to the detection device for detection. During the detection, the conveying device transports the second graphite boat buffered in the first buffer device to the tension correction device for tension correction. After the first graphite boat is detected, it is transferred by the conveying device to the second buffer device. Then, the second corrected graphite boat is transported to the detection device for detection. Then, the third graphite boat is fed to the tension correction device. Then, the conveying device puts the first graphite boat on the second buffer device into the first buffer device and then unloads it.

[0118] During this process, graphite boats that fail the inspection are transported again by the conveying device to the tension correction device. Graphite boats that fail the correction multiple times are marked and sent to the first buffer device for unloading. The first buffer device uses its own stacking function to buffer the graphite boats that have been inspected and those that are to be corrected.

[0119] The first buffer device, in conjunction with the second buffer device, buffers the graphite boat during the tightening and testing processes, ensuring smooth operation during these processes and keeping the tightening correction device and testing device constantly working.

[0120] The entire process is highly automated, which greatly improves the efficiency of graphite boat calibration. The overall structure is compact, and detection and calibration are carried out simultaneously, further improving the calibration efficiency.

[0121] The workflow of the aforementioned transport device is typically sequential, meaning that the transport device moves the graphite boat from the previous process to a temporary storage device. After calibration, the same transport device then moves the graphite boat to the next process. This sequential working mode has a significant bottleneck: the transport device needs to frequently travel back and forth during the transfer process, resulting in low equipment utilization.

[0122] Therefore, as shown in Figures 16(b) and 16(c), in one embodiment, to reduce equipment waiting time and improve equipment utilization, a handling device and a temporary storage device are added. Specifically, the chassis 10 is arranged from left to right as follows: a loading / unloading device 11, a first buffer device 12, a second buffer device 16, a tension correction device 13, a detection device 14, and a third buffer device 17. The handling device specifically includes: a frame, at least two second sliders 159, at least two second motors 1510, and at least two belts. The frame is provided with two slide rails spaced apart along its length. The two second sliders 159 are slidably mounted on the two slide rails, enabling... The second slider 159 is capable of moving along the length of the slide rail. Each second slider 159 has a locking assembly 1511, a lifting guide rail 158, and a gripping assembly. Two belts are spaced apart along the length of the two slide rails. The two second sliders 159 are connected to the two belts one-to-one via the locking assembly 1511. Two second motors 1510 are connected to the two belts respectively, and each second motor 1510 drives the corresponding belt. Each belt drives the corresponding slider to move on the second slide rail. The lifting guide rail 158 of each second slider 159 is set vertically, and the lifting guide rail 158 is connected to the gripping assembly located below. The gripping assembly is used to grip the graphite boat.

[0123] The improved working principle is as follows: The external feeder delivers the first and second graphite boats to the loading / unloading device. At this point, the first conveying device moves the first graphite boat to the tension adjustment position for tension adjustment, and moves the second graphite boat to the second buffer device for temporary storage. Then, the loading device delivers the third and fourth graphite boats. Subsequently, the second conveying device moves the adjusted first graphite boat from the tension adjustment position to the inspection station for inspection. The first conveying device then moves the third and fourth graphite boats from the loading / unloading device to the first and second buffer devices respectively for buffering. The second conveying device then moves the inspected first graphite boat to the third buffer device for buffering, and finally moves the tension-adjusted second graphite boat to the inspection station. The first graphite boat is inspected at the first buffer station. The second transport device moves the first graphite boat from the third buffer station to the first buffer station. At the same time, the loading and unloading device receives the fifth and sixth graphite boats. The first transport device moves the third graphite boat from the first buffer station to the tension adjustment station for tension adjustment. The second transport device moves the inspected second graphite boat to the third buffer station for temporary storage. The first transport device moves the adjusted third graphite boat to the inspection station for inspection and moves the fourth graphite boat from the second buffer station to the tension adjustment station for adjustment. The second transport device moves the second graphite boat to the first buffer station for buffering. The first transport device moves the first and second graphite boats in the first buffer station to the loading and unloading device for unloading.

[0124] As shown above, the improved solution, through the parallel operation of two sets of handling devices and a temporary storage device, can significantly improve the transfer efficiency and storage capacity of graphite boats. Specifically, the newly added handling device can work in conjunction with the original handling device, each responsible for transferring graphite boats between different processes, thereby reducing equipment waiting time and improving equipment utilization. Simultaneously, the newly added temporary storage device can store more graphite boats, providing greater buffer space for calibration and subsequent processes, increasing production capacity while also enhancing equipment stability and reliability.

Any simple changes or equivalent substitutions of the technical solutions that can be obviously obtained by those skilled in the art within the scope of the technology disclosed in this utility model shall fall within the scope of protection of this utility model.
