Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a welding workbench. Background Technology

[0002] The fuel tank is an important component of vehicles such as automobiles that use gasoline as their power source. Fuel tanks typically require welding of components such as fuel nozzles, hose clamps, carbon canister brackets, support blocks, and isolation valve brackets to facilitate the assembly of surrounding parts and the operation of the fuel tank.

[0003] Fuel tanks typically have protruding components such as screws on their surface, and the surface often has many protrusions. Existing welding workbenches have poor versatility and cannot meet the fixing requirements of various fuel tanks, resulting in excessively high processing costs and low processing efficiency.

[0007] In the welding workbench, multiple template components are detachably mounted on the base, allowing for the installation of appropriate template components according to the size and shape of the oil tank to limit its position. Simultaneously, the mounting bracket can drive the flipping drive and the clamping component to slide relative to the base to a first preset position, and the mounting bracket is restricted to the first preset position by a locking structure. This allows the clamping component to avoid parts and protrusions on the top surface of the oil tank and apply pressure to a suitable position on the top surface of the oil tank, thus fixing the oil tank to the base. Therefore, the welding workbench can meet the fixing requirements of different oil tanks, has strong versatility, effectively reduces processing costs, and improves processing efficiency.

One end of the connecting rod is accommodated in the insertion hole, and the other end of the connecting rod has a strip-shaped hole. The pressure rod can move along the strip-shaped hole to a second preset position. The fixing member connects the connecting rod and the pressure rod to restrict the pressure rod to the second preset position.

[0010] In one embodiment of this implementation, the locking mechanism includes a fixing plate and a locking member. The fixing plate is fixed on the base and has multiple connecting holes. When the mounting bracket slides relative to the base to the first preset position, the locking member can pass through the corresponding connecting hole and connect with the mounting bracket.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0047] Please see Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 , Figure 1 This is a schematic diagram of the structure of a general feeding device according to one embodiment of the present utility model; Figure 2 yes Figure 1 A schematic diagram of the welding workbench 500 in the general feeding device; Figure 4 yes Figure 2 A schematic diagram of the clamping mechanism 52 in the welding workbench 500; Figure 7 yes Figure 2 A schematic diagram of the template assembly 54 in the welding workbench 500; This embodiment of the invention provides a universal feeding device, which includes a frame 100, a welding workbench 500, and a transition table 600. Both the welding workbench 500 and the transition table 600 are mounted on the frame 100.

[0048] The welding workbench 500 in the general feeding device is described in detail below.

[0049] The welding workbench 500 includes a base 51, a clamping mechanism 52, a locking mechanism 53, and multiple template assemblies 54. The clamping mechanism 52 includes a mounting bracket 521, a tilting drive 522, and a clamping assembly 523. The mounting bracket 521 is slidably engaged with the base 51 and can slide relative to it to a first preset position. The tilting drive 522 is mounted on the mounting bracket 521 and connected to the clamping assembly 523. The tilting drive 522 drives the clamping assembly 523 to clamp the top surface of the oil tank. The locking mechanism 53 is located on the base 51 and connected to the mounting bracket 521 to restrict the mounting bracket 521 to the first preset position. The multiple template assemblies 54 are detachably mounted on the base 51. The multiple template assemblies 54 are used to jointly support the bottom surface of the oil tank and all abut against the sides of the oil tank to restrict the horizontal movement of the oil tank relative to the base 51.

[0050] Understandably, because different fuel tanks have different sizes and shapes, the template components 54 used to fix the fuel tanks also differ. By setting multiple template components 54 to be detachably mounted on the base 51, it is possible to replace the template components 54 according to the fuel tank to adapt to the fixing of the fuel tank. In this embodiment, the number of template components 54 is three to ensure sufficient contact with the fuel tank, restrict the horizontal movement of the fuel tank, and improve the welding quality.

[0051] It is understood that the flipping drive 522 is also used to drive the clamping assembly 523 away from the top surface of the oil tank after the oil tank is welded, so that the oil tank can leave the base 51. In this embodiment, there are two sets of clamping mechanisms 52, which are arranged side by side and have the same structure.

[0052] Understandably, the locking mechanism 53 is also used to disengage from the mounting bracket 521, thereby releasing the restriction on the mounting bracket 521 and allowing it to continue moving relative to the base 51 to be adjusted to a suitable position. For example, when another type of oil tank requires welding, the locking mechanism 53 can release the restriction on the mounting bracket 521, allowing the mounting bracket 521 to move relative to the base 51 to a first preset position. This allows the clamping assembly 523 to avoid screws and other components, as well as protrusions, on the top surface of the oil tank being processed, and to apply clamping force to a suitable position, so that the oil tank is firmly fixed to the base 51 under the action of clamping force.

[0053] It should be noted that the relatively protruding structure on the bottom surface of the fuel tank can be a component such as a screw, or it can be a protruding structure of the fuel tank itself. The first preset position refers to the position of the mounting bracket 521 relative to the base 51 when it can provide a good clamping force for the clamping assembly 523. The first preset position may be different when facing different fuel tank fixing situations, and it does not refer to a fixed position.

[0054] In the welding workbench 500, multiple template components 54 are detachably mounted on the base so that the corresponding template components 54 can be installed according to the size and shape of the oil tank to limit the oil tank. At the same time, the mounting bracket 521 can drive the flipping drive component 522 and the clamping component 523 to slide relative to the base 51 to the first preset position, and the mounting bracket 521 is restricted to the first preset position by the locking structure, so that the clamping component 523 can avoid the parts and protrusions on the top surface of the oil tank and apply pressure to the appropriate position on the top surface of the oil tank, so that the oil tank is fixed to the base 51. Therefore, the welding workbench 500 can meet the fixing requirements of different oil tanks, has strong versatility, effectively reduces processing costs, and improves processing efficiency.

[0055] In one embodiment of this implementation, please refer to Figure 2 , Figure 4 and Figure 5 , Figure 5 yes Figure 4 This is a schematic diagram of the clamping assembly 523 in the disassembled state of the clamping mechanism 52. The clamping assembly 523 includes a connecting structure 5231, a clamping structure 5232, and a first locking member 5233. The connecting structure 5231 has an insertion hole 5201 and a first locking hole 5202 communicating with the insertion hole 5201. One end of the clamping structure 5232 is accommodated in the insertion hole 5201. The first locking member 5233 is relatively movable and engages with the first locking hole 5202, and can abut against the clamping structure 5232 to prevent the clamping structure 5232 from leaving the insertion hole 5201. Specifically, the connecting structure 5231 is connected to the flipping drive member 522, and the clamping structure 5232 is used to clamp the top surface of the oil tank.

[0056] By configuring the first locking member 5233 to be relatively movable and engaged with the first locking hole 5202, when the clamping structure 5232 needs to be installed, the clamping structure 5232 can be inserted into the insertion hole 5201, and then the first locking member 5233 can be moved relative to it to abut against the clamping structure 5232, thereby restricting the clamping structure 5232 from leaving the insertion hole 5201, thus completing the installation of the clamping structure 5232. When the clamping structure 5232 needs to be disassembled, the first locking member 5233 can be moved to separate from the clamping structure 5232, thereby releasing the restriction on the clamping structure 5232, allowing the clamping structure 5232 to leave the insertion hole 5201, thus completing the disassembly of the clamping structure 5232. This configuration makes the installation and disassembly of the clamping structure 5232 on the connecting structure 5231 more convenient, facilitating the replacement of a dedicated clamping structure 5232 to meet the fixing requirements of different oil tanks, and further improving versatility.

[0057] It is understandable that some fuel tanks have a special structure, and the position of applying pressure may not be adjusted to the correct position by sliding the mounting bracket 521 relative to the base 51. In this case, the pressure position can be adjusted to the appropriate position by replacing the clamping structure 5232 in conjunction with the relative sliding of the mounting bracket 521, so that the fuel tank can be better fixed on the base 51.

[0058] In this embodiment, the first locking member 5233 is constructed as a hand-tightening screw so that the worker can manually tighten the locking member 532 to achieve installation or removal.

[0059] In one embodiment of this implementation, please refer to Figure 2 , Figure 4 and Figure 5 The clamping structure 5232 includes a connecting rod 52321, a pressure rod 52322, and a fixing member 52323. One end of the connecting rod 52321 is accommodated in the insertion hole 5201, and the other end of the connecting rod 52321 has a slotted hole 5203. The pressure rod 52322 can move along the slotted hole 5203 to a second preset position. The fixing member 52323 connects the connecting rod 52321 and the pressure rod 52322 to limit the pressure rod 52322 to the second preset position. With this configuration, the relative position of the pressure rod 52322 and the connecting rod 52321 can be adjusted through the slotted hole 5203 and the fixing member 52323, so that the pressure rod 52322 can apply the clamping force to a reasonable position on the top surface of the oil tank.

[0060] It should be noted that the second preset position refers to the position of the mounting bracket 521 relative to the base 51 when it can provide a better clamping force for the clamping component 523. The second preset position may be different when facing different oil tank fixing, and it does not refer to a fixed position.

[0061] In this embodiment, the fixing member 52323 is constructed as two nuts, both of which are threaded into the pressure rod 52322 and located on opposite sides of the connecting rod 52321. On one hand, by rotating the two nuts, the two nuts can clamp the connecting rod 52321, thereby fixing the relative position of the pressure rod 52322 and the connecting rod 52321. On the other hand, by rotating the two nuts, the position of the pressure rod 52322 relative to the connecting rod 52321 in the z-axis direction can be adjusted to adjust the clamping force.

[0062] In one embodiment of this implementation, please refer to Figure 3 , Figure 4 and Figure 6 , Figure 3 yes Figure 2 A schematic diagram of the welding workbench 500 from another perspective; Figure 6 yes Figure 2A schematic diagram of the locking mechanism 53 in the welding workbench 500 is shown. The locking mechanism 53 includes a fixing plate 531 and a locking member 532. The fixing plate 531 is fixed on the base 51 and has multiple connecting holes 5301. When the mounting bracket 521 slides relative to the base 51 to a first preset position, the locking member 532 can pass through the corresponding connecting hole 5301 and connect with the mounting bracket 521. With this configuration, the mounting bracket 521 can be restricted by the locking member 532 and the fixing plate 531. The structure is relatively simple and the cost is low.

[0063] Specifically, the locking element 532 can be connected to the mounting bracket 521 by means of snap-fit, abutment, threaded connection, etc., thereby restricting movement. In this embodiment, the locking mechanisms 53 of the two clamping structures 5232 share a fixed plate 531, and each mounting bracket 521 is fixed in position by two locking elements 532.

[0064] In one embodiment of this implementation, please refer to Figure 3 , Figure 4 and Figure 6 The mounting bracket 521 has locking holes 5204 for threaded engagement with the locking element 532. Specifically, the number of locking holes 5204 corresponds to the number of locking elements 532, with two in each case. This design allows the mounting bracket 521 to be restricted by rotating the locking element 532; the locking method is relatively simple and the operation is easy.

[0065] In this embodiment, the locking member 532 is constructed as a hand-tightening screw so that a worker can manually tighten the locking member 532 to restrict or release the restriction.

[0066] In one embodiment of this implementation, please refer to Figure 3 , Figure 4 and Figure 6 The base 51 is provided with a sliding rail 511 that slidably engages with the mounting bracket 521, and the arrangement direction of the plurality of connecting holes 5301 is parallel to the extension direction of the sliding rail 511. Specifically, in order to improve guiding accuracy, two sliding rails 511 are provided, and the two sliding rails 511 jointly engage with the mounting bracket 521. By aligning the arrangement direction of the plurality of connecting holes 5301 with the extension direction of the sliding rail 511, the locking member 532 can pass through the corresponding connecting hole 5301 and connect to the mounting bracket 521.

[0067] In one embodiment of this implementation, please refer to Figure 2 and Figure 7The template assembly 54 includes a mounting plate 541 and multiple templates 542. The multiple templates 542 are fixed on the mounting plate 541, and the mounting plate 541 is detachably connected to the base 51. With this configuration, multiple templates 542 can be replaced simultaneously by removing and installing the mounting plate 541 on the base 51, resulting in higher replacement efficiency.

[0068] In this embodiment, multiple mounting modules 542 are fixed to the mounting plate 541 by screw installation.

[0069] In one embodiment of this implementation, please refer to Figure 2 and Figure 7 The template assembly 54 includes a second locking member 543. One end of the second locking member 543 abuts against the mounting plate 541, and the other end of the second locking member 543 passes through the mounting plate 541 and engages with the base 51. This configuration allows for the assembly and disassembly of the mounting plate 541 and the base 51 through the second locking member 543. The structure is relatively simple and helps to reduce costs.

[0070] In this embodiment, the mounting plate 541 has a strip-shaped hole 5401, and the second locking member 543 is constructed as a hand-tightening screw. The head of the hand-tightening screw abuts against the side of the mounting plate 541 facing away from the base 51, and the shank of the hand-tightening screw passes through the strip-shaped hole 5401 and engages with the threaded part of the base 51, thereby realizing the installation of the mounting plate 541 and the base 51. Since the second locking member 543 is constructed as a hand-tightening screw, the worker can manually tighten the second locking member 543 to assemble and disassemble the mounting plate 541. Moreover, the presence of the strip-shaped hole 5401 ensures that the hand-tightening screw can engage with the threaded part of the base 51 after passing through, resulting in higher reliability.

[0071] In this embodiment, in order to improve the relative positional accuracy between the mounting plate 541 and the base 51, the base 51 is also provided with a positioning pin that can be positioned and cooperate with the mounting plate 541.

[0072] In this embodiment, there are two second locking members 543 to increase the connection strength between the mounting plate 541 and the base 51.

[0073] In one embodiment of this implementation, please refer to Figure 2 and Figure 7 The template assembly 54 includes a guide plate 545, which is mounted on the mounting plate 541 and used to guide the oil tank. It is understood that because different oil tanks have different sizes and shapes, the position and shape of the guide plate 545 will also differ. By setting the guide plate 545 on the mounting plate 541, when replacing an oil tank that needs to be fixed, the matching guide plate 545 can be replaced simultaneously by replacing the mounting plate 541, resulting in higher replacement efficiency and improved processing efficiency.

[0074] In one embodiment of this implementation, please refer to Figure 2 and Figure 7 The template assembly 54 includes a limiting rod 544, which is mounted on the mounting plate 541 and equipped with a photoelectric sensor 5441. The limiting rod 544 is used to abut against the side of the oil tank, and the photoelectric sensor 5441 is used to sense the distance to the oil tank. On the one hand, the presence of the limiting rod 544 ensures that the worker can push the oil tank into position, and the presence of the photoelectric sensor 5441 facilitates the automation of subsequent operations such as clamping by the clamping mechanism 52 after the oil tank is detected to be in position. On the other hand, since different oil tanks have different sizes and shapes, the positions of the limiting rod 544 for limiting the oil tank and the photoelectric sensor 5441 for detecting the position of the oil tank are also different. Therefore, setting the limiting rod 544 on the mounting plate 541 allows for synchronous replacement with multiple templates 542 and guide plates 545, further improving replacement efficiency and processing efficiency.

[0075] In this embodiment, there are two limiting rods 544, and each of the two limiting rods 544 is equipped with a photoelectric sensor 5441.

[0076] In one embodiment of this implementation, the welding workbench 500 further includes a lifting mechanism 57, which is mounted on the base 51. The lifting mechanism 57 supports the oil tank after it is loaded and lowers it after it is pushed into place, so that the oil tank is supported by multiple support modules 542. The lifting mechanism 57 is also used to raise the oil tank after welding is completed to facilitate unloading.

[0077] In one embodiment of this implementation, the welding workbench 500 further includes a transition rod 55 and a transition plate 56. Both the transition rod 55 and the transition plate 56 are mounted on the base 51. The transition rod 55 is used to load the oil tank from the transition table 600 to the lifting mechanism 57. The transition plate 56 is used to guide the oil tank during the loading process to prevent the oil tank from falling out during the loading process.

[0078] In one embodiment of this implementation, the welding workbench 500 further includes a plurality of material frames 58 for accommodating weldments to be welded onto the oil tank.

[0079] The following is a detailed description of the transition table 600 in the general feeding device.

[0080] This utility model provides a transition platform 600. Please refer to [link / reference]. Figure 1 and Figure 8 , Figure 8 yes Figure 1A schematic diagram of the transition platform 600 in the general feeding device is shown. The transition platform 600 includes a base 61 and two guide rods 62. The two guide rods 62 are parallel and adjustable in relative distance on the base 61. The two guide rods 62 jointly support the bottom surface of the oil tank, allowing the oil tank to slide along the guide rods 62. Each guide rod 62 has a clearance groove 6201, which is used to avoid relatively protruding structures on the bottom surface, so that the oil tank can enter or leave the base 51 along the arrangement direction of the two guide rods 62.

[0081] In this embodiment, there are two transition platforms 600, which are arranged opposite each other in the x-axis direction and have a gap between them, which is the loading / unloading area. The welding worktable 500 is located adjacent to the loading / unloading area in the y-axis direction. One of the two transition platforms 600 is used for loading the oil tank, and the other is used for unloading the oil tank. In this embodiment, the general feeding device also includes a feeding platform 700, which is located on one side of the unloading transition platform 600 in the y-axis direction.

[0082] In other embodiments, the transition table 600 may be provided in a single manner to perform one of the functions of loading and unloading, or to perform both functions of loading and unloading simultaneously.

[0083] Specifically, both the base 51 and the base 61 are fixed on the frame 100 to ensure that the base 51 and the base 61 have good relative positional accuracy, which is beneficial to improving the reliability of feeding.

[0084] In this embodiment, the extension direction of the guide rod 62 is parallel to the x-axis direction, and the arrangement direction of the two guide rods 62 is the y-axis direction, that is, the two guide rods 62 are spaced apart and arranged parallel to each other in the y-axis direction. During the feeding process, the worker first places the oil tank at the initial end of the guide rod 62 and pushes the oil tank to the end along the x-axis direction. At this time, the relatively protruding structure on the bottom surface of the oil tank corresponds to the position of the clearance groove 6201 (relative to each other in the y-axis direction), so that when the worker pushes the oil tank along the y-axis direction, the protruding structure can pass through the clearance groove 6201, so that the oil tank can leave the guide rod 62 and enter the base 51 of the welding workbench 500. During the unloading process, after the oil tank is welded on the welding workbench 500, the worker pushes the oil tank to move along the y-axis. At this time, the relatively protruding structure on the bottom surface of the oil tank corresponds to the position of the clearance groove 6201 (relative in the y-axis direction), so that the oil tank can move smoothly onto the two guide rods 62 and make the protruding structure and the guide rods 62 misaligned. The worker pushes the oil tank to move along the x-axis, so that the oil tank can slide along the guide rods 62 and leave.

[0085] In the transition table 600, the distance between the two guide rods 62 can be adjusted to ensure that the guide rods 62 can avoid the relatively protruding structures on the bottom surface of the oil tank during the sliding process of the oil tank along the guide rods 62, and that the clearance grooves 6201 on the guide rods 62 can allow the relatively protruding structures on the bottom surface of the oil tank to pass through after the oil tank moves along the guide rods 62. This allows the oil tank to leave the guide rods 62 along the arrangement direction of the two guide rods 62 and enter or leave the base 51. Therefore, the transition table 600 can meet the feeding requirements of different oil tanks, has strong versatility, effectively reduces processing costs, and improves processing efficiency.

[0086] In one embodiment of this implementation, please refer to Figure 1 , Figure 8 and Figure 9 , Figure 9 yes Figure 8 A schematic diagram of the guide structure 611 and guide rod 62 in the transition platform 600 is shown. The base 61 is provided with the guide structure 611, and at least one guide rod 62 is slidably engaged with the guide structure 611. The guide rod 62 is provided with a limiting structure 621, which can be connected to the guide structure 611 to limit the sliding of the guide rod 62. With this configuration, the guide rod 62 and the base 61 can be relatively fixed through the limiting structure 621.

[0087] Understandably, during the process of adjusting the relative distance between the two guide rods 62, the worker can first release the restriction on the guide rod 62 to slide along the guide structure 611 by connecting the limiting structure 621 to the guide structure 611, and then slide the guide rod 62 along the guide structure 611 to the appropriate position. By connecting the limiting structure 621 to the guide structure 611, the sliding of the guide rod 62 is restricted, so that the guide rod 62 and the base 61 are relatively fixed.

[0088] In this embodiment, both guide rods 62 are slidably engaged with the guide structure 611 and are each provided with a limiting structure 621 so that the positions of the two guide rods 62 on the base 61 are adjustable, thereby improving versatility.

[0089] In one embodiment of this implementation, please refer to Figure 1 , Figure 8 and Figure 9The limiting structure 621 includes a connecting block 6211, a clamping block 6212, and a driving member 6213. The connecting block 6211 is connected to the guide rod 62. One end of the clamping block 6212 is connected to the connecting block 6211 and surrounds the guide structure 611 with the connecting block 6211. The other end of the clamping block 6212 is connected to the connecting block 6211 via the driving member 6213. The driving member 6213 is used to drive the other end closer to the connecting block 6211, so that the connecting block 6211 and the clamping block 6212 cooperate to clamp the guide structure 611. With this configuration, the driving member 6213 can drive the connecting block 6211 and the clamping block 6212 to clamp the guide structure 611, thereby limiting the sliding of the guide rod 62 on the guide structure 611. At the same time, the driving member 6213 can also drive the connecting block 6211 and the clamping block 6212 to release the guide structure 611, thereby releasing the sliding restriction on the guide rod 62. The structure is relatively simple and helps to reduce costs.

[0090] In one embodiment of this implementation, please refer to Figure 1 , Figure 8 and Figure 9 One end of the driving component 6213 abuts against the clamping block 6212, and the other end of the driving component 6213 passes through the clamping block 6212 and is threaded into the connecting block 6211. With this configuration, the restriction or release can be achieved by rotating the driving component 6213, which is relatively simple to operate and highly efficient.

[0091] In this embodiment, the drive component 6213 is constructed as a hand-tightening screw so that a worker can manually tighten the drive component 6213 to achieve or remove the restriction.

[0092] In one embodiment of this implementation, please refer to Figure 1 , Figure 8 and Figure 9 To improve guiding accuracy, the guide structure 611 includes two parallel and spaced-apart slide rods 6111, and the guide rod 62 is provided with two sliders 622 that slide in cooperation with the corresponding slide rods 6111. Specifically, the connecting block 6211 is fixed on the slider 622, so that the limiting structure 621 can slide synchronously with the guide rod 62.

[0093] In one embodiment of this implementation, please refer to Figure 1 , Figure 8 and Figure 10 , Figure 10 yes Figure 8 The diagram shows the structure of the two guide rods 62 in the transition platform 600. Each guide rod 62 includes a detachably connected guide portion 613 and a clearance portion 614, which together form a clearance groove 6201. This configuration allows the shape of the clearance groove 6201 to be adjusted by replacing the clearance portion 614, thus helping the clearance groove 6201 to avoid protruding structures on the bottom surface of the fuel tank.

[0094] In one embodiment of this implementation, please refer to Figure 1 , Figure 8 and Figure 10 To improve the overall structural strength of the two guide rods 62, the clearance portions 614 of the two guide rods 62 are connected and fixed through the connecting portion 615. It is understandable that, since the two clearance portions 614 are connected and fixed through the connecting portion 615, when adjusting the distance between the two guide rods 62, the clearance portion 614 needs to be removed first. After adjustment, the other suitable clearance portion 614 is installed. This design facilitates adjustment of the clearance groove 6201 while ensuring the overall structural strength of the two guide rods 62.

[0095] In one embodiment of this implementation, please refer to Figure 1 , Figure 8 and Figure 10 In order for the guide part 613 and the air-shielding part 614 to jointly support the bottom of the oil tank, the top sides of the guide part 613 and the air-shielding part 614 are flush.

[0096] In one embodiment of this implementation, please refer to Figure 1 , Figure 8 and Figure 10 The transition platform 600 includes a stop bar 63, which is connected to the guide bar 62 and abuts against the side of the oil tank to prevent the oil tank from leaving the guide bar 62. This design prevents the oil tank from falling off the side of the stop bar 63, improving the safety of loading.

[0097] In one embodiment of this implementation, please refer to Figure 1 , Figure 8 and Figure 10 To accommodate the anti-fall requirements of different fuel tanks, the distance between the stop lever 63 and the guide rod 62 is adjustable in the arrangement direction.

[0098] In this embodiment, the stop lever 63 is provided with an adjustment structure 631, and the distance between the stop lever 63 and the guide rod 62 is adjusted through the adjustment structure 631.

[0099] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
