Bending equipment

Abstract

The present invention relates to a bending device, including a carrying plate, a clamping mechanism, a first bending mechanism and a second bending mechanism. By setting the above-mentioned bending device, a metal sheet is placed on the carrying plate and clamped by the clamping mechanism, and then the metal sheet is bent for the first time by the first telescopic end of the first bending mechanism, and then the bent metal sheet is bent for the second time by the second telescopic end of the second bending mechanism, and the bending angle of the metal sheet is set to a preset angle during the second bending. The preset angle can be determined according to the material of the metal sheet, and specifically according to the rebound of the metal sheet. For example, if the metal sheet is required to be bent 90°, the preset angle is the required bending angle plus the rebound angle. In this way, it is ensured that the bending angle of the metal sheet after the second bending reaches the required angle, and the accuracy of the bending angle can be effectively ensured, thereby ensuring the safety of the adapter formed by the bending in the battery.

Description

Technical Field

[0001] The invention relates to the technical field of metal sheet processing equipment, in particular to a bending equipment. Background Art

[0002] Nowadays, with the advent of the information and high-tech era, the form of energy application is changing, and the demand for renewable, pollution-free, small and discrete portable high-performance power sources is growing rapidly. All countries are vigorously developing green and efficient secondary batteries. As a new type of secondary battery, lithium-ion batteries have the advantages of high energy density and power density, high operating voltage, light weight, small size, long cycle life, good safety, and green environmental protection. They have broad application prospects in portable appliances, power tools, large energy storage, and electric transportation power sources.

[0003] The important components of lithium batteries include adapters, top covers and battery cells. The adapter is arranged between the top cover and the battery cell. The adapter needs to be bent during its production process. Specifically, two parts of a metal sheet that were originally in a horizontal state are rotated around the center line with the bending line as the center line to a required angle with the horizontal plane. However, the existing metal sheet bending is usually carried out by moving the bending block up and down to drive the bent part to rotate and bend. Since the metal sheet will rebound, the accuracy of the bending angle cannot be guaranteed. The low accuracy of the bending angle will affect the subsequent use of the adapter in the battery and affect the performance of the battery. Summary of the invention

[0004] Based on this, it is necessary to provide a bending device that can ensure the bending angle of the metal sheet to address the problem that the existing metal sheet bending angle has low accuracy and affects its use.

The second telescopic end can press the bent metal sheet to continue bending toward the clamping mechanism during the reciprocating movement along the second direction.

[0010] By setting up the above-mentioned bending equipment, the metal sheet is placed on the supporting plate and pressed by the clamping mechanism, and then the metal sheet is bent for the first time by the first telescopic end of the first bending mechanism, and then the bent metal sheet is bent for the second time by the second telescopic end of the second bending mechanism, and the bending angle of the metal sheet during the second bending is made to be a preset angle.

[0011] The preset angle can be determined according to the material of the metal sheet, and specifically according to the rebound of the metal sheet. For example, if the metal sheet is required to be bent 90°, the preset angle is the required bending angle plus the rebound angle. In this way, the bending angle of the metal sheet after the secondary bending is ensured to reach the required angle, which can effectively ensure the accuracy of the bending angle, thereby ensuring the safety of the adapter formed by the bending in the battery.

[0015] The bracket is reciprocatably disposed on the mounting frame along a third direction perpendicular to the first direction, and is used to adjust the position of the bearing plate relative to the clamping mechanism.

[0016] In one embodiment, the clamping mechanism includes a second driving member and a pressure block assembly, and the second driving member is transmission-connected to the pressure block assembly to drive the pressure block assembly to reciprocate along the first direction. The pressure block assembly can be pressed against the metal sheet during the reciprocating movement along the first direction.

[0017] In one embodiment, the pressure block assembly includes a mounting structure and a protrusion structure, wherein the mounting structure is transmission-connected to the second driving member, and the mounting structure can be pressed against the metal sheet during the reciprocating movement along the first direction. The protrusion structure is arranged on the side of the mounting structure along the second direction toward the second bending mechanism, and is used to provide support for the metal sheet when the second telescopic end presses against the metal sheet and continues to bend toward the clamping mechanism.

[0018] In one of the embodiments, the pressing block assembly further includes a flexible pad, which is disposed at one end of the mounting structure along the first direction and is used to press against the metal sheet during the reciprocating movement of the mounting structure along the first direction.

[0019] In one of the embodiments, the bending device further includes a positioning mechanism, which is disposed on the supporting plate and is used to form a fixing position on the supporting plate for fixing the metal sheet.

[0020] In one embodiment, the positioning mechanism includes a first positioning component and a second positioning component both disposed on the carrier plate;

[0038] like Figure 1 and Figure 2 As shown, a bending device 100 provided in an embodiment of the present invention includes a carrying plate 30 , a clamping mechanism 40 , a first bending mechanism 50 and a second bending mechanism 60 .

[0039] The pressing mechanism 40 is used to press the metal sheet 200 onto the carrying plate 30 .

[0040] The first bending mechanism 50 has a first telescopic end 51 that can reciprocate along a first direction. The first telescopic end 51 can pass through the through hole 34 and bend the metal sheet 200 toward the pressing mechanism 40 during the reciprocating movement along the first direction.

[0041] The second bending mechanism 60 has a second telescopic end 61 , which can reciprocate along a second direction that is angled with the first direction. During the reciprocating movement along the second direction, the second telescopic end 61 can press the bent metal sheet 200 to continue bending toward the clamping mechanism 40 .

[0042] Specifically, the first direction is perpendicular to the second direction. Figure 1 The up and down directions shown, the second direction is Figure 1 Meanwhile, in practical applications, for the convenience of operation, the first direction is the vertical direction and the second direction is the horizontal direction.

[0043] By setting up the above-mentioned bending equipment 100, the metal sheet 200 is placed on the supporting plate 30 and clamped by the clamping mechanism 40, and then the metal sheet 200 is bent for the first time by the first telescopic end 51 of the first bending mechanism 50, and then the bent metal sheet 200 is bent for the second time by the second telescopic end 61 of the second bending mechanism 60, and the bending angle of the metal sheet 200 during the second bending is made to be a preset angle.

[0044] The preset angle can be determined according to the material of the metal sheet 200, and more specifically, according to the rebound of the metal sheet 200. For example, if the metal sheet 200 is required to be bent 90°, the preset angle is the required bending angle plus the rebound angle. In this way, the bending angle of the metal sheet 200 after the secondary bending is ensured to reach the required angle, which can effectively ensure the accuracy of the bending angle, thereby ensuring the safety of the adapter formed by the bending in the battery.

[0045] See also Figure 3 and Figure 4 The metal sheet 200 in the present invention generally includes a first sheet 201 and a second sheet 202 connected to each other. Before bending, the first sheet 201 and the second sheet 202 are in the same plane. After the bending process, it is necessary to ensure that the angle between the first sheet 201 and the second sheet 202 is the required angle.

[0046] It should be explained that the bending angle of the metal sheet 200 is the angle at which the second sheet 202 rotates (or bends) relative to the first sheet 201, and the angle between the first sheet 201 and the second sheet 202 is the internal angle of the metal sheet 200, that is, the supplementary angle of the bending angle. At the same time, the bending device in the above embodiment is used to bend the metal sheet 200 that requires a larger bending angle, and is actually applied to the metal sheet 200 with a bending angle of at least 90°.

[0047] at the same time, Figure 2 FIG. 2 is a schematic diagram of a bending process of a metal sheet 200 in an embodiment. Specifically, Figure 2 Figure A in the middle is a schematic diagram of the metal sheet 200 being pressed by the pressing end 41. Figure 2 Figure B is a schematic diagram of the second sheet 202 being bent for the first time by the first telescopic end 51. Figure 2 Figure C is a schematic diagram of the second telescopic end 61 moving toward the second piece 202 that has been bent at a certain angle.

[0048] and Figure 3 and Figure 4 Figures A to B in the figure are schematic diagrams of the structures of the first sheet 201 and the second sheet 202 of the metal sheet 200 before and after bending in one embodiment.

[0049] In some embodiments, the bending equipment also includes a mounting frame 10 and a bracket 20, the clamping mechanism 40 is arranged on the mounting frame 10, and the bracket 20 is reciprocatingly arranged on the mounting frame 10 along a third direction perpendicular to the first direction. The supporting plate 30, the first bending mechanism 50 and the second bending mechanism 60 are all arranged on the bracket 20, and the bracket 20 reciprocates along the third direction to adjust the position of the supporting plate 30 relative to the clamping mechanism 40, that is, to adjust the position of the metal sheet 200 on the supporting plate 30 relative to the clamping mechanism 40.

[0050] The bracket 20 has a pressing position during the reciprocating movement along the third direction. When the bracket 20 is located at the pressing position, the pressing mechanism 40 can press the metal sheet 200 against the bearing surface 32 .

[0051] Of course, the reciprocating movement of the bracket 20 along the third direction can also realize moving the carrier plate 30 from the loading station to the pressing station, and the pressing station is the position of the carrier plate 30 when the bracket 20 is in the pressing position.

[0052] Furthermore, the mounting frame 10 includes a base plate 12 and a support portion 14, the bracket 20 is reciprocally movably arranged on the base plate 12 along a third direction, the support portion 14 is connected to the same side of the base plate 12 where the bracket 20 is arranged, the clamping mechanism 40 is arranged on the support portion 14, and when the bracket 20 is in the clamping position, the clamping assembly corresponds to the supporting plate 30 in the first direction.

[0053] Specifically, a slide rail 91 extending longitudinally along the third direction is disposed on the bottom plate 12 , and a slider slidably matched with the slide rail 91 is disposed at the bottom of the bracket 20 .

[0054] In some embodiments, the bending device further includes a first driving member 92, which is disposed on the mounting frame 10 and is transmission-connected to the bracket 20 to drive the bracket 20 to reciprocate along the third direction. In practical applications, the first driving member 92 is disposed on the bottom plate 12. Specifically, the first driving member 92 is a cylinder, an electric cylinder, or a linear module.

[0055] In some embodiments, the third direction is the same as the second direction, that is, the third direction is Figure 1 In other embodiments, the third direction may also be other directions perpendicular to the first direction, which is not limited here.

[0056] In some embodiments, the carrying plate 30 has a carrying surface 32 and a connecting plate on two opposite sides in the first direction. The carrying surface 32 is used to carry the metal sheet 200 , and the pressing mechanism 40 is used to press the metal sheet 200 against the carrying surface 32 .

[0057] Furthermore, the carrying plate 30 also has a through hole 34 penetrating the carrying surface 32 and the connecting surface. The first telescopic end 51 can pass through the through hole 34 and bend the metal sheet 200 toward the pressing mechanism 40 during the reciprocating movement along the first direction.

[0058] In this way, the metal sheet 200 can be placed on the supporting surface 32, and the first sheet 201 and the second sheet 202 are arranged along the second direction, wherein the first sheet 201 is pressed by the pressing mechanism 40, and the first sheet 201 is located on the side of the through hole 34 away from the second bending mechanism 60, and the second sheet 202 at least covers part of the through hole 34, and then the first telescopic end 51 of the first bending mechanism 50 moves along the first direction and passes through the through hole 34, abuts against the second sheet 202 during the passing process, and pushes it to bend a certain angle relative to the first sheet 201 toward the pressing mechanism 40, and then the second telescopic end 61 of the second bending mechanism 60 extends. Since the second sheet 202 has been bent at a certain angle, the second telescopic end 61 presses on the second sheet 202 that has been bent at a certain angle when it extends, and presses it to continue to bend to a preset angle toward the pressing mechanism 40.

[0059] See also Figure 1 and Figure 5 In some embodiments, the pressing mechanism 40 has a pressing end 41 facing the bearing surface 32, and the pressing end 41 can reciprocate along the first direction, and the pressing end 41 can press against the metal sheet 200 during the reciprocating movement along the first direction. In practical applications, when the bracket 20 is in the pressing position, the pressing end 41 corresponds to the metal sheet 200 on the bearing surface 32 in the first direction, and corresponds to the first sheet 201, so as to press against the first sheet 201 when moving toward the bearing surface 32 along the first direction.

[0060] See also Figure 1 and Figure 5 In some embodiments, the clamping mechanism 40 includes a second driving member 42 and a pressing block assembly 44, and the second driving member 42 is transmission-connected to the pressing block assembly 44 to drive the pressing block assembly 44 to reciprocate along the first direction. The pressing block assembly 44 can be pressed against the metal sheet 200 during the reciprocating movement along the first direction.

[0061] Furthermore, the pressing block assembly 44 includes a mounting structure 442 and a protrusion structure 444. The mounting structure 442 is transmission-connected to the second driving member 42. The mounting structure 442 can press against the metal sheet 200 during the reciprocating movement along the first direction. The protrusion structure 444 is arranged on the side of the mounting structure 442 toward the second bending mechanism 60 along the second direction, and is used to provide support for the metal sheet 200 when the second telescopic end 61 presses the metal sheet 200 to continue bending toward the clamping mechanism 40, so as to ensure that the metal sheet 200 is pressed and bent to a preset angle during the second bending.

[0062] When placing the metal sheet 200, ensure that the second sheet 202 corresponds to the protruding structure 444 in the second direction, that is, the mounting structure 442 is pressed against the position on the first sheet 201 corresponding to the second sheet 202, and the protruding structure 444 is arranged on the side of the structure facing the second bending mechanism 60. When the second telescopic end 61 pushes the second sheet 202 to bend, the second sheet 202 can abut against the protruding structure 444.

[0063] In this way, the shape and size of the protruding structure 444 can be set according to the required bending angle of the second sheet 202. Taking the case where the second sheet 202 is required to bend 90° and the rebound angle is determined as an example, it is only necessary to ensure that when the second sheet 202 is pushed by the second telescopic end 61 and abuts against the protruding structure 444, the bending angle of the second sheet 202 is the sum of 90° and the rebound angle. After the second telescopic end 61 is withdrawn, it can be ensured that the second sheet 202 rebounds to 90°, thereby effectively ensuring the accuracy of the bending angle of the second sheet 202.

[0064] In some embodiments, the protruding structure 444 has an inclined surface 4441 on one side away from the mounting structure 442 along the second direction. The inclined surface 4441 is inclined relative to the first direction. When the second telescopic end 61 presses the bent metal sheet 200 to continue bending toward the clamping mechanism 40, the metal sheet 200 can abut and fit against the inclined surface 4441.

[0065] Furthermore, the distance between the top of the inclined surface 4441 and the mounting structure 442 is smaller than the distance between the bottom of the inclined surface 4441 and the mounting structure 442, that is, the inclined surface 4441 is Figure 5 The setting is shown tilted from top to bottom and towards the right.

[0066] When the second sheet 202 is pushed by the second telescopic end 61 to continue to bend, it can abut and fit against the inclined surface 4441. In this way, the angle of the inclined surface 4441 relative to the first direction needs to be determined according to the material of the metal sheet 200 to ensure that the second sheet 202 rebounds to the required bending angle after the second telescopic end 61 is withdrawn.

[0067] At the same time, in order to ensure that the second sheet 202 can abut and fit against the inclined surface 4441 during the continued bending process, the distance between the inclined surface 4441 and the second sheet 202 in the second direction should not be too large, that is, the size of the protruding structure 444 needs to be determined according to actual conditions to avoid the second sheet 202 being bent at too large an angle before it can abut and fit against the inclined surface 4441.

[0068] In some embodiments, the protruding structure 444 further has an arcuate surface 4442 connected to the inclined surface 4441, the arcuate surface 4442 protrudes outward from the protruding structure 444, and is located at the bottom of the protruding structure 444. Figure 2It can be seen that when the mounting structure 442 is pressed against the first sheet 201, the arc surface 4442 of the raised structure 444 is ensured to be located at the connection between the first sheet 201 and the second sheet 202, so that in the process of bending the second sheet 202, the bending part of the first sheet 201 and the second sheet 202 can be abutted against the arc surface 4442, thereby ensuring the shape of the bending part and preventing damage to the bending part.

[0069] In some embodiments, the pressing block assembly 44 further includes a flexible pad 446, which is disposed at one end of the mounting structure 442 away from the second driving member 42, and is used to press against the first sheet 201 during the reciprocating movement of the mounting structure 442 along the first direction. Specifically, the flexible pad 446 is a soft material, preferably a polyurethane material, which can avoid crushing the metal sheet 200 and also increase the strength of the pressing to prevent the metal sheet 200 from moving.

[0070] See also Figure 1 and Figure 6 In some embodiments, the first bending mechanism 50 includes a third driving member 52 and a bending assembly. The third driving member 52 is disposed on the bracket 20. The third driving member 52 is transmission-connected to the bending assembly to drive the bending assembly to reciprocate along the first direction. The bending assembly has a first telescopic end 51.

[0071] Furthermore, the bending assembly includes a mounting block 54 and a rolling member 56. The mounting block 54 is transmission-connected to the third driving member 52. The rolling member 56 is rotatably connected to an end of the mounting block 54 away from the third driving member 52 around a rotation axis perpendicular to the first direction and the second direction. The rolling member 56 is used to press the metal sheet 200 during the reciprocating movement of the mounting block 54 along the first direction to bend the metal sheet 200 toward the clamping mechanism 40.

[0072] In practical applications, the corresponding connection surface of the third driving member 52 is located on one side of the supporting plate 30 , and the rolling member 56 can pass through the through hole 34 during the reciprocating movement along the first direction to press the metal sheet 200 located on the supporting surface 32 .

[0073] It can be understood that during the reciprocating movement of the above-mentioned mounting block 54 along the first direction, part of the mounting block 54 and the rolling member 56 can pass through the through hole 34. Therefore, the first telescopic end 51 in the above-mentioned embodiment includes the part of the mounting block 54 that can pass through the through hole 34 and the rolling member 56.

[0074] The rolling member 56 is rotatable along the rotation axis. When the rolling member 56 moves along the first direction through the through hole 34, it abuts against the second sheet 202. At the same time, when the rolling member 56 continues to move and pushes the second sheet 202 to bend, the rolling member 56 can roll on the second sheet 202. Compared with pushing the second sheet 202 to bend by moving on the surface of the second sheet 202, the rolling of the rolling member 56 effectively reduces the friction and avoids the wear of the second sheet 202.

[0075] Specifically, the rolling member 56 is a roller, and the end of the mounting block 54 away from the third driving member 52 has a spaced mounting arm, and the roller is rotatably disposed between the two mounting arms around the rotation axis. Of course, the roller can also be connected to the mounting block 54 in other ways, as long as the roller can be pressed against the metal sheet 200 when the mounting block 54 moves along the first direction, and can roll on the metal sheet 200, so as to bend the metal sheet 200 toward the pressing mechanism 40.

[0076] In some embodiments, the size of the through hole 34 matches the orthographic projection of the first telescopic end 51 on the connection surface, that is, the size of the through hole 34 is slightly larger than the orthographic projection of the first telescopic end 51 on the connection surface to facilitate the passage of the first telescopic end 51.

[0077] When the metal sheet 200 is placed on the supporting surface 32, ensure that the connection between the first sheet 201 and the second sheet 202 is located at a side edge of the through hole 34 along the second direction. In this way, when the first telescopic end 51 passes through the through hole 34 and pushes the second sheet 202 to bend, the first telescopic end 51 can bend the second sheet 202 90°.

[0078] Of course, in other embodiments, the first telescopic end 51 can also bend the second piece 202 into other angles not exceeding 90°, as long as the bent second piece 202 can be pressed by the second telescopic end 61 that reciprocates along the second direction.

[0079] It can be understood that when the connection between the first sheet 201 and the second sheet 202 is located at the side edge of the through hole 34 along the second direction, the bracket 20 is moved to the clamping position, the clamping end 41 clamps the first sheet 201, and the arc surface 4442 of the protruding structure 444 is located at the connection between the first sheet 201 and the second sheet 202.

[0080] In addition, the bracket 20 has multiple pressing positions. When the bracket 20 is located at any pressing position, the pressing end 41 can press the metal sheet 200. Under the premise that the pressing end 41 and the protruding structure 444 do not affect the movement of the first telescopic end 51, when the bracket 20 is located at different pressing positions, the positions of the pressing end 41 and the protruding structure 444 relative to the metal sheet 200 also change, so the bending positions of the first sheet 201 and the second sheet 202 also change accordingly. In this way, the length of the two mutually perpendicular sides formed after bending can be adjusted, that is, the length of the bent side can be adjusted.

[0081] See also Figure 1 and Figure 6 In some embodiments, the second bending mechanism 60 includes a fourth driving member 62 and a push plate 64. The fourth driving member 62 is disposed on the bearing surface 32, and the fourth driving member 62 is transmission-connected to the push plate 64 to drive the push plate 64 to reciprocate along the second direction. The push plate 64 has the above-mentioned second telescopic end, that is, the push plate 64 can press the bent metal sheet 200 to continue to bend toward the clamping mechanism 40 during the movement.

[0082] In practical applications, one end of the push plate 64 away from the fourth driving member 62 has a contact surface, and the contact surface is used to contact the second sheet 202 bent at a certain angle. Specifically, the contact surface is perpendicular to the second direction.

[0083] In some embodiments, the bending device further includes a positioning mechanism 70 , which is disposed on the bearing surface 32 and is used to form a fixed position for fixing the metal sheet 200 on the bearing surface 32 , and the through hole 34 is at least partially located at the fixed position.

[0084] It is understandable that, since the second sheet 202 needs to be bent, the above-mentioned fixing position is used to locate the position of the first sheet 201 to ensure that the first sheet 201 can be pressed onto the bearing surface 32 by the pressing end 41 .

[0085] In practical applications, the positioning mechanism 70 further includes a first positioning assembly 74 and a second positioning assembly 76, which are spaced apart in a fourth direction perpendicular to the first direction and the second direction, and the positioning block 72, the first positioning assembly 74 and the second positioning assembly 76 are used to enclose the above-mentioned fixed position on the bearing surface 32. The fourth direction is Figure 1 Left and right directions shown.

[0086] In some embodiments, the first positioning assembly 74 includes a fifth driving member and a push block. The fifth driving member is disposed on the bearing surface 32 and is transmission-connected to the push block to drive the push block to reciprocate along the fourth direction, thereby releasing or positioning the metal sheet 200 on the bearing surface 32.

[0087] In other embodiments, the second positioning assembly 76 has the same structure as the first positioning assembly 74, and the push block of the first positioning assembly 74 and the push block of the second positioning assembly 76 are arranged opposite to each other in the fourth direction. Of course, in other embodiments, one of the first positioning assembly 74 or the second positioning assembly 76 may include the fifth driving member and the push block, and the other may only be provided with a push block fixed on the bearing surface 32, which can also realize positioning and releasing the metal sheet 200 on the bearing surface 32.

[0088] In some embodiments, the bending equipment also includes a positioning block 72 arranged on the supporting plate 30, and the positioning block 72 and the second bending mechanism 60 are spaced apart in the second direction, and are used to press the metal sheet 200 against the second telescopic end 61 to limit the metal sheet 200 during the process of continuing to bend toward the clamping mechanism 40, so as to prevent the metal sheet 200 from moving during the second bending process.

[0089] Furthermore, the positioning block 72 is located on the bearing surface 32 and on the other side of the through hole 34 along the second direction opposite to the push plate 64. The push plate 64 can move closer to or farther away from the positioning block 72 during the reciprocating movement along the second direction. In this way, when the push plate 64 performs the second bending on the metal sheet 200, the positioning block 72 can limit the movement of the metal sheet 200 in the second direction.

[0090] In some embodiments, the second driving member 42, the third driving member 52, the fourth driving member 62 and the fifth driving member in the above embodiments can all be driving mechanisms such as a cylinder or an electric cylinder, which is not limited here.

[0091] In order to facilitate understanding of the technical solution of the present invention, the working process of the bending device in a specific embodiment is described here:

[0092] Initially, the bracket 20 is located at the loading station to load the metal sheet 200. After loading, the metal sheet 200 is positioned at a fixed position by the positioning mechanism 70, and then the first driving member 92 drives the bracket 20 to move along the third direction to the clamping position.

[0093] After the bracket 20 reaches the clamping position, the second driving member 42 drives the pressing block assembly 44 to move downward and press on the first sheet 201, and the protruding structure 444 of the pressing block assembly 44 is located at the bending part of the first sheet 201 and the second sheet 202, and then the third driving member 52 drives the mounting block 54 and the rolling member 56 to move upward through the through hole 34, and push the second sheet 202 to bend 90°, then the mounting block 54 and the rolling member 56 move downward to make way for the push plate 64, the fourth driving member 62 drives the push plate 64 to move toward the bent second sheet 202, and pushes the second sheet 202 to continue to bend until it abuts against the inclined surface 4441 of the protruding structure 444, after the push plate 64 is withdrawn, the second sheet 202 rebounds a certain angle, and the angle between the second sheet 202 and the first sheet 201 is 90°.

[0094] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
