Description

Technical Field

[0001] The utility model relates to the technical field of handling equipment, in particular to a clamp and a palletizing system. Background Art

[0002] When the air conditioner outdoor units are off the production line after being packed and sealed, they will be stacked into specific stacks by palletizing robots and then transported to the warehouse for temporary storage. In order to save space, the general stacks are three rows and two columns with two layers, three rows and two columns with three layers, or three rows and a single column with two layers. The outdoor units of household air conditioners to be transported are generally of moderate size and weight, and multi-layer palletizing can be achieved by robots in conjunction with side clamping fixtures to achieve automatic handling and palletizing of air conditioners. However, the weight of some commercial air conditioner outdoor units to be transported can reach more than 100kg. Although the side clamping fixture is flexible to operate, its clamping force is often insufficient when facing heavy air conditioning equipment, which can easily cause the equipment to slip or be damaged. Therefore, the solution mostly adopted by the industry for transporting heavy air conditioners is to use a lifting mechanism to first lift the bottom of the air conditioner to a certain gap, and then use a clamp with a supporting part (such as Figure 1 ) to lift the air conditioner and move it to a specific platform with clearance. However, the fixture support is fixed, which means that the air conditioner can only be placed in a single layer during transportation, and multi-layer stacking of the air conditioner cannot be achieved. It is still necessary to manually drive a plywood forklift to stack the single-layer air conditioner into a double layer, which greatly reduces the transportation efficiency of the air conditioner.

[0003] Therefore, it is necessary to improve the existing air conditioning fixture to overcome the defects of the prior art. Utility Model Content

[0004] In order to overcome the problems existing in the related art, one of the purposes of the utility model is to provide a clamp, which can clamp the items to be transported through the clamping plate, and can support the items from the bottom through the supporting member. The clamp has a wide range of applications, and is particularly suitable for the transfer and stacking of heavy weight products, which can improve logistics efficiency and reduce product handling costs.

[0005] A clamp comprises a base, on which two clamps capable of relative movement are arranged; a supporting member is arranged at the bottom of each clamp, and the supporting member is hinged to the clamp;

[0006] The supporting members of the two clamping plates are arranged opposite to each other, and a bearing space is formed between the two clamping plates and the supporting members.

[0007] The base can be designed as a stable rectangular frame to ensure the overall stability and load-bearing capacity of the fixture. The supporting member can rotate freely within a certain range. The supporting members of the two clamps are arranged relative to each other. When the two clamps move toward each other, the supporting member also rotates and gradually approaches, and together with the two clamps, forms a bearing space.

[0008] The clamp can not only clamp the items to be transported through the clamping plate, but also support the items from the bottom through the supporting member, thereby ensuring the stability and safety of heavy-weight products during the transport process.

[0009] In a preferred technical solution of the utility model, the opposite sides of the two clamping plates respectively form clamping surfaces, and each of the clamping surfaces is provided with a first anti-slip structure.

[0010] The first anti-skid structure can be a series of evenly distributed anti-skid lines, convex points or a special material coating with increased friction coefficient. In practical applications, when the two clamps move towards each other to clamp an object, the first anti-skid structure contacts the surface of the object, effectively increasing the friction between the clamping surface and the object.

[0011] In a preferred technical solution of the utility model, a mounting surface is provided on the side of the clamping plate away from the clamping surface, a mounting seat is provided on the mounting surface, and the supporting member is hinged to the mounting seat via a mounting shaft.

[0012] In a preferred technical solution of the utility model, a first driving mechanism is arranged on the mounting surface, a first connecting seat is arranged on the supporting member, and a connecting shaft is arranged on the first connecting seat; the output end of the first driving mechanism is rotatably matched with the connecting shaft;

[0013] The output end of the first driving mechanism is extended and retracted to drive the supporting member to rotate along the axis of the installation shaft.

[0014] The output end of the first driving mechanism is in rotational cooperation with the connecting shaft. When the output end of the first driving mechanism performs a telescopic action, it drives the supporting member to rotate along the axis of the installation shaft.

[0015] In actual application, when the angle of the supporting member needs to be adjusted to accommodate objects of different sizes and shapes, the first driving mechanism will perform corresponding telescopic actions according to the instructions of the control system. This design not only allows the angle of the supporting member to be flexibly adjusted, but also ensures the automation and accuracy of the supporting process.

[0016] In a preferred technical solution of the utility model, the clamping plate includes a first substrate and a second substrate, the second substrate is fixed to the middle of the first substrate, and the second substrate and the first substrate are perpendicular to each other;

[0017] A plurality of ribs are arranged between the first substrate and the second substrate.

[0018] A plurality of ribs are also arranged between the first substrate and the second substrate. Specifically, the ribs are evenly distributed and tightly combined with the two substrates to form a solid support structure. The presence of the ribs not only increases the overall strength of the splint, but also effectively prevents the substrate from being deformed when subjected to the pressure of heavy objects.

[0019] In practical applications, when the clamp clamps a heavy commercial air conditioner or other items, the combined structure of the first substrate, the second substrate and the ribs can withstand greater pressure and torque, ensuring the safety and stability of the clamping process.

[0020] In a preferred technical solution of the utility model, a second anti-slip structure is arranged on the top of the supporting member, and a weight sensor is arranged on the bottom of the supporting member.

[0021] The second anti-slip structure can increase the friction between the supporting member and the object to prevent the object from sliding or shifting during transportation.

[0022] A weight sensor is also integrated at the bottom of the support. This sensor can monitor the weight of the items placed on the support in real time and transmit the data to the control system. Through the feedback of the weight sensor, the operator can accurately understand the weight of the current transported items, thereby ensuring the safety and efficiency of the transport process. In addition, the weight sensor can also be connected to the control system of the fixture to achieve automatic control and weight monitoring during the transport process.

[0023] In a preferred technical solution of the utility model, a guide rail is provided on the base, the guide rail is provided along the length direction of the base, a slider is provided on the guide rail, the clamping plate is fixed on the slider, and the clamping plate slides on the guide rail along with the slider;

[0024] The base is provided with a second driving mechanism, and the second driving mechanism drives the sliding block to move on the guide rail.

[0025] In a preferred technical solution of the utility model, the second driving mechanism includes a motor and a screw rod, a connecting block is provided on the clamping plate, and second connecting seats are provided on opposite sides of the base;

[0026] The screw rod has a first end and a second end that are arranged opposite to each other. The first end of the screw rod passes through the connecting block and is rotatably connected to the second connecting seat. The screw rod is threadedly connected to the connecting block. The second end of the screw rod is fixedly connected to an output end of the motor.

[0027] When the screw rotates, the connecting block (and the clamping plate fixed thereon) will move along the guide rail. The second end of the screw is fixedly connected to the output end of the motor, and the motor drives the screw to rotate. In actual operation, when the position of the clamping plate needs to be adjusted, the motor is started to drive the screw to rotate. Due to the threaded connection between the screw and the connecting block, the connecting block (and the clamping plate) will move precisely along the guide rail until it reaches the desired position. This design not only improves the flexibility of the clamp, but also ensures the accuracy of the clamping position.

[0028] In a preferred technical solution of the utility model, a distance sensor is provided on each of the clamps, and the distance sensors on the two clamps are arranged opposite to each other. The distance sensor can measure the distance between the two clamps in real time, so as to accurately control the opening and closing degree of the clamps and ensure accurate clamping of objects of different sizes. In addition, the distance sensor can also be connected to the control system of the clamp to provide real-time distance data to help operators or automation systems make more accurate control decisions. This design not only improves the clamping accuracy of the clamp, but also greatly reduces the possibility of operating errors.

[0029] A second objective of the present utility model is to provide a palletizing system, comprising a palletizing robot and a lifting mechanism, wherein the palletizing robot is arranged on one side of the lifting mechanism, and the palletizing robot is provided with the clamp as described above.

[0030] The beneficial effects of the utility model are:

[0031] The utility model provides a clamp, which includes a base, on which two clamps that can move relatively are arranged; a supporting member is arranged at the bottom of each clamp, and the supporting member is hinged to the clamp so that the supporting member can rotate freely within a certain range. The supporting members of the two clamps are arranged relative to each other, and a bearing space is formed between the two clamps and the supporting member. In practical applications, when it is necessary to carry a heavy commercial air conditioner or other product, the clamp is first moved to the vicinity of the product, and then the positions of the two clamps are adjusted to align with the two sides of the product. Subsequently, the clamps are driven to move toward each other until the clamps tightly clamp the two sides of the product. At the same time, the supporting member rotates during the movement of the clamp, and supports the product from the bottom of the product to provide a stable supporting force. When the product is transported to the target position, the supporting member slowly rotates until it no longer supports the product, and then the two clamps move away from each other to place the product at the target position. The clamp can not only clamp the items to be transported through the clamping plate, but also support the items from the bottom through the supporting member, thereby ensuring the stability and safety of heavy-weight products during transportation, improving logistics efficiency and reducing product transportation costs.

[0032] The present application also provides a palletizing system including the above-mentioned clamp, which can realize the automation of the transfer and palletizing of heavy-weight products through the cooperation of a palletizing robot, a clamp and a lifting mechanism, thereby saving manpower and material resources for product handling and reducing production costs.

[0043] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0044] Some commercial air conditioners to be transported have an external unit that weighs up to 100kg. Although the side clamps are flexible to operate, they are often insufficient in clamping force when facing heavy air conditioners, which can easily cause the equipment to slip or be damaged. Therefore, the solution used by the industry to transport heavy air conditioners is to first use a lifting mechanism to lift the bottom of the air conditioner to a certain gap, and then use a clamp with a supporting part (such as Figure 1) to lift the air conditioner and move it to a specific platform with clearance. However, the fixture support is fixed, which means that the air conditioner can only be placed in a single layer during transportation, and multi-layer stacking of the air conditioner cannot be achieved. It is still necessary to manually drive a plywood forklift to stack the single-layer air conditioner into a double layer, which greatly reduces the transportation efficiency of the air conditioner.

[0045] Based on this, the present application provides a clamp.

[0046] Example 1

[0047] like Figure 1-Figure 8 As shown, the clamp provided in this embodiment includes a base 1, on which two clamping plates 2 that can move relatively are arranged; a supporting member 3 is arranged at the bottom of each clamping plate 2, and the supporting member 3 is hinged to the clamping plate 2 so that the supporting member 3 can rotate freely within a certain range. The supporting members 3 of the two clamping plates 2 are arranged opposite to each other, and a bearing space 6 is formed between the two clamping plates 2 and the supporting members 3.

[0048] Specifically, the base 1 can be designed as a stable rectangular frame to ensure the overall stability and load-bearing capacity of the fixture. In practical applications, when it is necessary to carry heavy commercial air conditioners or other products, the fixture is first moved to the vicinity of the product, and then the positions of the two clamps 2 are adjusted to align with the two sides of the product. Subsequently, the clamps 2 are driven to move toward each other until the clamps 2 tightly clamp the two sides of the product. At the same time, the supporting member 3 rotates during the movement of the clamps 2, providing support for the product from the bottom of the product and providing a stable supporting force. When the product is transported to the target position, the supporting member 3 slowly rotates until it no longer supports the product, and then the two clamps 2 move away from each other to place the product at the target position. The fixture can not only clamp the items to be transported through the clamps 2, but also support the items from the bottom through the supporting member 3, thereby ensuring the stability and safety of heavy products during transportation, improving logistics efficiency, and reducing product transportation costs.

[0049] The supporting member 3 can rotate freely within a certain range. The supporting members 3 of the two clamping plates 2 are arranged relative to each other. When the two clamping plates 2 move toward each other, the supporting member 3 also rotates and gradually approaches, and forms a bearing space 6 together with the two clamping plates 2.

[0050] The clamp can not only clamp the items to be transported through the clamping plate 2, but also support the items from the bottom through the supporting member 3, thereby ensuring the stability and safety of heavy-weight products during transportation.

[0051] In a better implementation of this embodiment, a distance sensor 5 is provided on each of the clamps 2, and the distance sensors 5 on the two clamps 2 are arranged opposite to each other. The distance sensor 5 can measure the distance between the two clamps 2 in real time, so as to accurately control the opening and closing degree of the clamps 2, and ensure accurate clamping of objects of different sizes. In addition, the distance sensor 5 can also be connected to the control system of the clamp to provide real-time distance data to help operators or automation systems make more accurate control decisions. This design not only improves the clamping accuracy of the clamp, but also greatly reduces the possibility of operating errors.

[0052] The distance measuring sensor of the present application can be any one of an infrared distance measuring sensor, a laser distance measuring sensor or an ultrasonic distance measuring sensor; for example, an infrared distance measuring sensor is installed on each clamping plate 2 to measure the distance between the two clamping plates 2 in real time.

[0053] In actual applications, in the control system of the clamp, the size of the object to be clamped is first input. Such as the width of products such as air conditioners, refrigerators, and televisions. During the clamping process, the infrared distance sensor 5 on each clamping plate 2 continuously emits infrared rays and receives the signal reflected by the other clamping plate 2, thereby measuring the distance between the two clamping plates 2 in real time. These distance data are transmitted to the control system in real time. After receiving the data from the infrared distance sensor 5, the control system processes it according to the preset algorithm. The system compares the distance between the two clamping plates 2 with the preset target clamping distance to determine whether the relative position of the clamping plates 2 needs to be adjusted. If the measured distance is greater than the target clamping distance, the control system will decide to reduce the distance between the two clamping plates 2; otherwise, it will increase the distance. According to the results of data processing and decision-making, the control system sends control instructions to the two clamping plates 2 respectively, and the control system can accurately control the relative movement of the two clamping plates 2 to achieve appropriate clamping force and stability. During the clamping process, the control system can also continuously monitor the distance between the two clamping plates 2 and adjust it in real time as needed to ensure the safety and stability of the clamping.

[0054] It should be noted that the algorithm preset in this application is a prior art, and this application does not protect the algorithm. Therefore, the working logic of the algorithm will not be described in detail.

[0055] Example 2

[0056] This embodiment is improved on the basis of embodiment 1.

[0057] like Figure 1-Figure 8 As shown, in this embodiment, two opposite side surfaces of the two clamping plates 2 respectively form clamping surfaces, and a first anti-slip structure 24 is provided on the clamping surfaces.

[0058] The first anti-skid structure 24 can be a series of evenly distributed anti-skid lines, convex points or a special material coating with increased friction coefficient. In practical applications, when the two clamping plates 2 move towards each other to clamp an object, the first anti-skid structure 24 contacts the surface of the object, effectively increasing the friction between the clamping surface and the object.

[0059] In this embodiment, a second anti-slip structure is disposed on the top of the supporting member 3, and a weight sensor is disposed on the bottom of the supporting member 3 in the bearing space 6. Specifically, the first anti-slip structure 24 and the second anti-slip structure may be the same.

[0060] The first anti-skid structure 24 and the second anti-skid structure significantly increase the friction between the clamping plate 2 and the object, thereby enhancing the stability of the clamping. During the transportation process, even if there is a bump or tilt, the object can be effectively prevented from slipping, ensuring the safety of transportation.

[0061] A weight sensor is also integrated at the bottom of the support. This sensor can monitor the weight of the items placed on the support 3 in real time and transmit the data to the control system. Through the feedback of the weight sensor, the operator can accurately understand the weight of the current transported items, thereby ensuring the safety and efficiency of the transport process. In addition, the weight sensor can also be connected to the control system of the fixture to achieve automatic control and weight monitoring during the transport process. The weight sensor can monitor the weight of the items in real time, provide accurate data support for the operator, and ensure the safety of the transport process. By monitoring the weight in real time, the operator can adjust the transport strategy more efficiently, reduce unnecessary pauses and inspection time, and improve work efficiency.

[0062] In a more preferred embodiment, the weight sensor can be used in conjunction with an alarm device such as a buzzer. When the weight supported by the supporting member 3 exceeds a threshold, the buzzer alarm alerts the staff to pay attention, thereby preventing the supporting member 3 from being used for a long time in an environment where the weight exceeds its own supporting weight, thereby extending the service life of the supporting member 3.

[0063] Example 3

[0064] This embodiment is improved on the basis of embodiment 1.

[0065] like Figure 1-Figure 8 As shown, in this embodiment, a mounting surface is provided on the side of the clamping plate 2 facing away from the clamping surface, a mounting seat 31 is provided on the mounting surface, and the supporting member 3 is hinged to the mounting seat 31 via a mounting shaft 32 .

[0066] In this embodiment, the mounting surface is provided with a first driving mechanism 4, the supporting member 3 is provided with a first connecting seat 33, and the first connecting seat 33 is provided with a connecting shaft 34; the output end of the first driving mechanism 4 is rotatably matched with the connecting shaft 34;

[0067] The output end of the first driving mechanism 4 is extended and retracted to drive the supporting member 3 to rotate along the axis of the installation shaft 32 .

[0068] The output end of the first driving mechanism 4 is rotatably matched with the connecting shaft 34. When the output end of the first driving mechanism 4 performs a telescopic action, it drives the supporting member 3 to rotate along the axis of the installation shaft 32.

[0069] In actual application, when the angle of the supporting member 3 needs to be adjusted to accommodate objects of different sizes and shapes, the first driving mechanism 4 will perform corresponding telescopic actions according to the instructions of the control system. This design not only allows the angle of the supporting member 3 to be flexibly adjusted, but also ensures the automation and accuracy of the supporting process.

[0070] The first driving mechanism 4 of the present application can be a cylinder, and one end of the piston rod of the cylinder is rotatably matched with the connecting shaft 34, so the extension and contraction of the cylinder can drive the supporting member 3 to rotate. The first driving mechanism 4 realizes the automatic adjustment of the supporting member 3, without manual operation, which simplifies the operation process. Since the angle of the supporting member 3 is adjustable, the clamp is not only suitable for heavy objects such as commercial air conditioners, but also can be applied to other objects that require flexible support, showing a wide range of applicability.

[0071] Example 4

[0072] This embodiment is improved on the basis of embodiment 1.

[0073] like Figure 1-Figure 8 As shown, in this embodiment, the clamping plate 2 includes a first substrate 21 and a second substrate 22, the second substrate 22 is fixed to the middle of the first substrate 21, and the second substrate 22 and the first substrate 21 are perpendicular to each other;

[0074] A plurality of ribs 23 are disposed between the first substrate 21 and the second substrate 22 .

[0075] Specifically, the first substrate 21 and the second substrate 22 are arranged in a T-shape, and a limiting space for the object to be clamped can be formed between the first substrate 21 and the second substrate 22 .

[0076] A plurality of ribs 23 are also arranged between the first substrate 21 and the second substrate 22. Specifically, 3 to 5 ribs 23 may be arranged. These ribs 23 are evenly distributed and tightly combined with the two substrates to form a solid support structure. The presence of the ribs 23 not only increases the overall strength of the clamp 2, but also effectively prevents the substrate from being deformed when subjected to the pressure of a heavy object. Through a reasonable layout of the substrate and the ribs 23, a lightweight design of the clamp 2 can be achieved, which reduces the overall weight of the clamp and facilitates handling and operation.

[0077] In practical applications, when the clamp clamps a heavy commercial air conditioner or other items, the combined structure of the first substrate 21, the second substrate 22 and the ribs 23 can withstand greater pressure and torque, ensuring the safety and stability of the clamping process. The stable clamping plate 2 design reduces downtime caused by loosening or damage of the clamp during handling and improves work efficiency.

[0078] Example 5

[0079] This embodiment is improved on the basis of embodiment 1.

[0080] like Figure 1-Figure 8 As shown, in this embodiment, a guide rail 11 is provided on the base 1, and the guide rail 11 is provided along the length direction of the base 1. A slider 12 is provided on the guide rail 11, and the clamping plate 2 is fixed on the slider 12. The clamping plate 2 slides on the guide rail 11 along with the slider 12;

[0081] The base 1 is provided with a second driving mechanism 13 , and the second driving mechanism 13 drives the slider 12 to move on the guide rail 11 .

[0082] The guide rail 11 of the present application can be provided as a whole or in two sections, each section of the guide rail 11 being used to carry a clamping plate 2. More preferably, two guide rails 11 can be provided in the same section, and the two guide rails 11 are parallel to each other to effectively support and guide the movement of the clamping plate 2.

[0083] In a more specific implementation of this embodiment, the second driving mechanism 13 includes a motor and a screw rod 15, a connecting block 25 is provided on the clamping plate 2, and second connecting seats 14 are provided on two opposite sides of the base 1; the motor can be a servo motor.

[0084] The screw rod 15 has a first end and a second end that are arranged opposite to each other. The first end of the screw rod 15 passes through the connecting block 25 and is rotatably connected to the second connecting seat 14. The screw rod 15 is threadedly connected to the connecting block 25. The second end of the screw rod 15 is fixedly connected to the output end of the motor, and the motor drives the screw rod to rotate.

[0085] Specifically, in one embodiment, the motor of the present application is a single-axis motor, and the output end of the single-axis motor outputs power to two screw rods 15 through a transmission shaft and two couplings, and a coupling is provided at the second end of each screw rod. In another embodiment, the motor of the present application can also be a dual-axis motor, and the two output shafts of the dual-axis motor are located on the same straight line, and the two output shafts of the dual-axis motor are respectively fixedly connected to a screw rod. When the two output shafts of the dual-axis motor rotate, the two screw rods 15 are driven to rotate, and when the screw rods 15 rotate, the connecting block 25 (and the clamping plate 2 fixed on the connecting block 25) will move along the guide rail 11.

[0086] In actual operation, when the position of the clamping plate 2 needs to be adjusted, the motor is started to drive the screw rod 15 to rotate. Due to the threaded connection between the screw rod 15 and the connecting block 25, the connecting block 25 and the clamping plate 2 will move accurately along the guide rail 11 until they reach the desired position. This design not only improves the flexibility of the clamp, but also ensures the accuracy of the clamping position.

[0087] The present application realizes the automation of the movement of the clamping plate 2 by driving the screw rod 15 to rotate through a motor, thereby improving work efficiency.

[0088] Example 6

[0089] like Figure 1-Figure 8 As shown, this embodiment provides a palletizing system, including a palletizing robot 100 and a lifting mechanism. The palletizing robot 100 is arranged on one side of the lifting mechanism, and the palletizing robot 100 is provided with the clamp as described above.

[0090] The working process of the palletizing system of the present application is described in detail below.

[0091] Before clamping the product to be transferred, the two clamps 2 move away from each other (the distance between the clamps 2 can be set according to the actual size of the clamped product). At this time, the surface of the supporting member 3 is in a horizontal state, and the position is to be clamped. After the product to be transferred is positioned and lifted by the lifting mechanism, the palletizing robot 100 drives the clamp to the clamping position, and the clamps 2 on both sides are tightened to clamp the two sides of the product to be transferred. After the distance between the two clamps 2 reaches the preset value, the clamps 2 stop moving. The second driving mechanism 13 locks the position of the clamps 2 to complete the clamping action; then the palletizing machine moves the product to be transferred to the palletizing position and starts the palletizing action. When palletizing, the clamp needs to be placed 50mm above the palletizing plane. After it is in place, the first driving mechanism 4 cylinder drives the supporting member 3 to be retracted, and at the same time, the two clamps 2 move away from each other, and the product to be transferred falls to complete the single-layer stacking. When multi-layer stacking is performed, the top surface of the previous layer of the product to be transferred is regarded as the palletizing plane, and the rest of the actions are the same. The sensor equipped on the clamping plate 2 can accurately sense whether the product is in place before clamping, whether the clamping plate 2 is clamped, and whether the handling process is abnormal, ensuring the stability of the entire clamping, handling, and stacking process. In addition to air conditioners to be transported, the system and clamp of the present application are also suitable for the handling and stacking of a variety of large-volume cubic products such as refrigerators and washing machines.

[0092] The key point of the present application is that it has both a clamp 2 and a support member 3, and the support member 3 is a rotatable structure. The design of the rotating support plate enables the fixture of the present application to have the ability to support large commercial external machine products to be transported, and does not affect the flexibility of stacking multi-layer products. Compared with the traditional bottom support plate fixed type fixture that can only stack a single layer, and also requires a manual driving clamp 2 forklift to stack the single layer of products to be transported into piles, the stacking robot 100 installed with the fixture of the present application can directly realize the stacking of multi-layer products to be transported, and can achieve the beneficial effect of reducing one person and a clamp 2 forklift in actual production. For the convenience of description, space relative terms such as "above...", "above...", "on the upper surface...", "above", etc. can be used here to describe the spatial position relationship between a device or feature as shown in the figure and other devices or features. It should be understood that the space relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the figure. For example, if a device in a drawing is inverted, a device described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above" can encompass both "above" and "below." The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0093] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0094] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
