During this process, the clamping mechanism keeps clamping the battery; S4, matching and plugging: the plugging mechanism presses the acid pot downward in two stages so that its spout structure is aligned and plugged with the acid filling port of the battery below. During this process, the clamping mechanism keeps clamping the battery; S5, finished product flows out and the mechanism is reset.

[0007] Preferably, in step S3, during the pressing down process of the acid pot, the guide part on the spout structure thereof is guided and inserted into the positioning hole of the positioning mechanism for calibration and alignment.

[0008] Preferably, before the second stage pressing in step S4, the positioning mechanism is moved away to make way for the plug-in matching action of the acid pot and the battery.

[0009] Preferably, in step S2, the plug-in mechanism, the positioning mechanism and the second conveying module are arranged in sequence from top to bottom, the first conveying module and the feeding module are arranged in sequence from top to bottom and are located on one side of the plug-in mechanism, the second conveying module conveys the battery to the bottom of the positioning mechanism to wait for the plug-in operation, and the feeding mechanism feeds the acid pot horizontally to just above the battery.

[0010] Preferably, in step S2, when the acid pot is pushed sideways between the feeding and the plug-in mechanism and the positioning mechanism, there is a height difference between the acid pot and the bottom of the plug-in mechanism.

[0011] Preferably, the clamping mechanism is arranged to move with the plug-in mechanism, and the lifting and lowering action of the plug-in mechanism drives the clamping mechanism to lift and lower synchronously. In steps S3-S4, the clamping mechanism always keeps clamping the acid pot; the plug-in mechanism is arranged as a double-cylinder structure, each performing one-stage and two-stage pressing operations.

[0012] Preferably, the clamping mechanism is vertically slidably installed on the feeding mechanism, and the plug-in mechanism and the clamping mechanism are dynamically connected via a transverse slide.

[0020] Embodiment 1 like Figure 1 As shown, a high-efficiency and high-precision assembly process for a battery acid filling pot comprises: S1, synchronous loading at the top and bottom: the acid pot 10 is continuously fed and loaded by the first conveying module at the top and turned over to an inverted state, and at the same time, the battery 20 is continuously fed and loaded by the second conveying module at the bottom to the plug-in matching station with the acid pot 10; S2, acid pot feeding: the acid pot 10 in an inverted state is clamped by the clamping mechanism 3 of the feeding module, and then pushed sideways by the feeding mechanism 4 to feed the acid pot between the plug-in mechanism 1 and the positioning mechanism 2; S3, acid pot positioning and calibration: the plug-in mechanism 1 presses the acid pot 10 downward for a period of time, and cooperates with the positioning mechanism 2 to calibrate the pot spout structure 101. During step S3, the clamping mechanism 3 keeps clamping the battery 20; S4, matching and plugging: the plugging mechanism 1 presses the acid pot 10 downward in two stages, so that the pot spout structure 101 is aligned and plugged with the acid filling port 201 of the battery 20 below. During step S4, the clamping mechanism 3 keeps clamping the battery 20; S5, finished product flows out and the mechanism is reset.

[0021] Fig.12 The flow path of the clamping mechanism 3 in this embodiment is shown, including clamping operation and resetting, wherein the solid line portion is the flow path of the clamping operation, and the dotted line portion is the flow path of the resetting operation.

[0022] Preferably, in step S2, the plug-in mechanism 1, the positioning mechanism 2 and the second conveying module are sequentially arranged from top to bottom, the first conveying module and the feeding module are distributed up and down and are located on one side of the plug-in mechanism 1, the second conveying module conveys the battery 20 to the bottom of the positioning mechanism 2 to wait for the plug-in operation, and the feeding mechanism 4 feeds the acid pot 10 horizontally to just above the battery 20.

[0023] In this embodiment, the acid pot 10 and the battery 20 are loaded by synchronously conveying them up and down, and then the acid pot 10 is moved down so that its spout structure 101 is matched and plugged with the acid filling port 201 of the battery 20 below. The acid pot 10 is pressed down in multiple stages, wherein the spout structure 101 is calibrated and aligned with the positioning mechanism 2 in the first stage of pressing down, and the spout structure 101 is quickly aligned and plugged with the acid filling port 201 below in the second stage of pressing down. The whole process of pressing down the acid pot 10 is realized by the follow-up action of the clamping mechanism 3 of the feeding module and the plugging mechanism 1, so that the acid pot always keeps the positioning and clamping state, the overall process is compactly coordinated, and the plugging work efficiency is high.

[0024] Preferably, in step S3, when the acid pot 10 is pressed down, the guide portion 104 on the spout structure 101 thereof is guided and inserted into the positioning hole 21 of the positioning mechanism 2 for calibration and alignment.

[0025] Preferably, before the second-stage pressing in step S4, the positioning mechanism 2 is moved away to make way for the plug-in matching action of the acid pot 10 and the battery 20.

[0026] Preferably, in step S2 , when the acid pot 10 is pushed sideways to feed between the plug-in mechanism 1 and the positioning mechanism 2 , there is a height difference between the acid pot 10 and the bottom of the plug-in mechanism 1 .

[0027] In the present embodiment, during the process of the acid pot 10 being pushed sideways to the feeding position between the plug-in mechanism 1 and the positioning mechanism 2, there is a slight height difference between the acid pot 10 and the bottom of the plug-in mechanism 1. One of the functions is that after being pushed sideways into place, when the plug-in mechanism 1 presses down the acid pot 10, due to the slight height difference between the acid pot 10 and the plug-in mechanism 1, that is, the two are not rigidly abutted, but there is a certain downward pressure buffer and elastic rebound, so that the guide part 104 of the spout structure 101 itself can automatically correct the slight skew that may occur. If the acid pot 10 and the plug-in mechanism 1 are rigidly abutted at the beginning, then if the guide part 104 is skewed, it will be more and more stuck in the skewed state when pressed down, and it is difficult to achieve the correction effect or even cause the guide part 104 to be crushed. The second function is to make way for the side pushing operation to avoid friction between the two and affect the side pushing and damage the acid pot 10.

[0028] As a supplementary explanation, a slight height difference is set between the acid pot 10 and the bottom of the plug-in mechanism 1 , and the height difference is sufficient to allow the acid pot 10 to be smoothly pushed sideways to the bottom of the plug-in mechanism 1 without causing friction with the plug-in mechanism 1 .

[0029] Preferably, the clamping mechanism 3 is arranged to move with the plug-in mechanism 1, and the lifting and lowering action of the plug-in mechanism 1 drives the clamping mechanism 3 to lift and lower synchronously, so that in steps S3-S4, the clamping mechanism 3 always keeps clamping the acid pot 10; the plug-in mechanism 1 is arranged as a double-cylinder structure, so that each performs the first-stage and second-stage pressing operations.

[0030] In this embodiment, the plugging operation is realized by a single drive of the plugging mechanism 1 to realize a multi-stroke action, thereby completing the positioning and calibration of the spout structure 101 of the acid pot 10, the alignment and plugging with the battery 20, and the self-resetting actions in sequence.

[0031] In addition, the clamping mechanism 3 and the plug-in mechanism 1 can be vertically followed and independently moved laterally, thereby realizing independent lateral movement and feeding of the clamping mechanism 3 and the clamping mechanism 3 moving downward with the plug-in mechanism 1, so that during the plug-in process, the acid pot 10 can always maintain a clamped state.

[0032] Preferably, the clamping mechanism 3 is vertically slidably installed on the feeding mechanism 4, and the plug-in mechanism 1 and the clamping mechanism 3 are dynamically connected via a transverse slide 30, so that the clamping mechanism 3 can be synchronously lifted and lowered with the plug-in mechanism 1 and can be driven by the feeding mechanism 4 alone to move laterally.

[0033] Preferably, in step S1, the first conveying module and the second conveying module are vertically distributed, and the storage battery 20 and the acid pot 10 are synchronously fed to the plug-in matching stations of the two.

[0034] Preferably, in step S1, the first conveying module includes a first conveying line 5, a first conveying mechanism 6 and a loading mechanism 7. The first conveying line 5 continuously transmits the upright acid pot 10. The first conveying mechanism 6 pushes the acid pots 10 to the side one by one to distribute the materials. The next acid pot 10 that receives the side-pushing distribution further pushes the previous acid pot 10 to the loading mechanism 7. The loading mechanism 7 flips the acid pot 10 to an inverted state.

[0035] Preferably, the second conveying module includes a second conveying line 8 and a second conveying mechanism 9. The second conveying line 8 continuously transmits the batteries 20. The second conveying mechanism 9 pushes the batteries 20 to the side one by one. The next battery 20 receiving the side push pushes the previous battery 20 further to the bottom of the positioning mechanism 2.

[0036] In this embodiment, the acid pot 10 and the battery 20 are loaded synchronously from top to bottom, and a double-station feeding method is used with an intermediate waiting position to improve the continuous feeding efficiency and avoid the long pushing stroke and long loading time of a single-station, which affects the efficiency.

[0037] Embodiment 2 This embodiment provides a high-efficiency and high-precision assembly device for a battery acid filling pot, which adopts a high-efficiency and high-precision assembly process for a battery acid filling pot in the above embodiment, such as Figure 2-Figure 3 As shown, including: A first conveying module and a second conveying module, wherein the first conveying module continuously conveys the acid pot 10 for loading, and the second conveying module continuously conveys the storage battery 20 for synchronous loading; like Figure 3 As shown, the plug-in mechanism 1 and the positioning mechanism 2 are arranged vertically and horizontally, and the battery 20 is transported by the second transport module to the bottom of the positioning mechanism 2 to wait for the plug-in operation; and A feeding module clamps the acid pot 10 in an inverted state and feeds the acid pot between the plug-in mechanism 1 and the positioning mechanism 2. The plug-in mechanism 1 first presses the acid pot 10 downward in one stage to cooperate with the positioning mechanism 2 to calibrate the spout structure 101, and then presses the acid pot 10 downward in a second stage to align the spout structure 101 with the acid filling port 201 of the battery 20 below for plugging.

[0038] As a supplementary explanation, the acid pot 10 in an inverted state refers to a state in which the spout structure 101 of the acid pot 10 faces downward.

[0039] Preferably, the plug-in mechanism 1, the positioning mechanism 2 and the second conveying module are arranged in sequence from top to bottom, and laterally in parallel, the first conveying module and the feeding module are arranged up and down, the second conveying module conveys the battery 20 to the bottom of the positioning mechanism 2, and the feeding module feeds the acid pot 10 laterally to just above the battery 20.

[0040] In this embodiment, the plug-in mechanism 1, the positioning mechanism 2 and the second conveying module are sequentially arranged from top to bottom, and the first conveying module and the feeding module are sequentially arranged in parallel from top to bottom. The first conveying module and the second conveying module respectively synchronously convey the acid pot 10 and the battery 20 for loading, and then the plug-in mechanism 1 drives the acid pot 10 to move downward so that its spout structure 101 is matched and plugged with the acid filling port 201 of the battery 20 below. The acid pot is pressed down in multiple stages by the plug-in mechanism 1. In the first stage of pressing down, the spout structure 101 is calibrated and aligned with the positioning mechanism 2 to ensure that the acid pot 10 can be quickly and accurately matched and effectively plugged with the battery 20 later. In the second stage of pressing down, the spout structure 101 is quickly aligned and plugged with the acid filling port 201. The structural design is compact and ingenious, the coordination between the mechanisms is compact, and the plugging work efficiency is high.

[0041] As a preference, Fig. 9 As shown, the plug-in mechanism 1 includes: a plug-in drive part 11, which is vertically installed on a frame and provides a segmented vertical driving force; and a pressing part 12, which is installed on the bottom driving end of the plug-in drive part 11 to be driven by the plug-in drive part 11 to move up and down.

[0042] In this embodiment, a multi-stroke action is realized by a single drive of the plug-in mechanism 1, thereby completing the positioning calibration of the acid kettle spout structure, the alignment plugging with the battery, and the self-resetting and other actions in sequence.

[0043] As a preference, Figure 7-Figure 8 As shown, the positioning mechanism 2 includes: a positioning component 22, and a positioning hole 21 is provided on the positioning component 22. Fig. 9 As shown, during a stage of downward pressing of the acid pot 10, the spout structure 101 thereof is guided and inserted into the positioning hole 21 of the positioning mechanism 2 to calibrate the possible skewness; and a positioning drive unit 23, wherein the positioning drive unit 23 drives the positioning assembly 22 to move so as to make way for the plug-in cooperation between the acid pot 10 and the battery 20.

[0044] In the present embodiment, during the process of the acid pot 10 being moved downward for insertion, the spout structure 101 thereof is first inserted into the positioning hole 21 of the positioning mechanism 2 to obtain a positioning and calibration operation before insertion. The positioning hole 21 is set to an inverted cone shape, which can mainly compensate for the possible skewness of the spout structure 101, especially the guide part 104, and guide the spout structure 101 to correct the skewness, thereby ensuring that the guide part 104 can be quickly and smoothly aligned with the acid adding port 201 when it is subsequently inserted.

[0045] Preferably, the positioning holes 21 are arranged in one-to-one correspondence with the spout structure 101, and the positioning holes 21 are arranged in an inverted cone shape that is larger at the top and smaller at the bottom, so as to gradually guide the spout structure 101 to the correct position.

[0046] As a preference, Figure 8 As shown, the positioning assembly 22 includes: a left positioning portion 221 and a right positioning portion 222 in a mirror-symmetrical structure, which are arranged to move relative to each other left and right and cooperate and splice to form the positioning hole 21 when the two are closed. The positioning drive portion 23 is drivingly connected to the left positioning portion 221 and the right positioning portion 222 to drive the left positioning portion 221 and the right positioning portion 222 to close or open.

[0047] In this embodiment, after the positioning before plugging is completed, the left positioning portion 221 and the right positioning portion 222 are opened to make way to avoid interference, so that the spout structure 101 is further moved downward to align with the acid filling port 201 of the battery 20 for plugging.

[0048] As a preference, Figure 4 As shown, the feeding module includes: a clamping mechanism 3, which clamps the acid pot 10 fed by the first conveying module; and a feeding mechanism 4, which is installed on a frame and drives the clamping mechanism 3 to move laterally to push the clamping mechanism 3 to the bottom of the plug-in mechanism 1 or to reset the clamping mechanism 3; wherein the clamping mechanism 3 is arranged to move with the plug-in mechanism 1, and the lifting and lowering action of the plug-in mechanism 1 drives the clamping mechanism 3 to lift and lower synchronously, so that during the calibration and plug-in process, the clamping mechanism 3 always keeps clamping the acid pot 10.

[0049] In this embodiment, the clamping mechanism 3 is arranged to move vertically with the plug-in mechanism 1 , so that the clamping mechanism 3 always positions and holds the acid pot 10 in an inverted state during the entire plug-in process.

[0050] As a preference, Figure 6 As shown, the clamping mechanism 3 is vertically slidably installed on the feeding mechanism 4, and the plug-in mechanism 1 and the clamping mechanism 3 are dynamically connected via a transverse slide 30. The transverse slide 30 is fixedly installed on the clamping mechanism 3 and has a long groove 301 transversely opened thereon. One end of the pressing portion 12 of the plug-in mechanism 1 is slidably installed in the long groove 301 via a roller, so that the clamping mechanism 3 can be synchronously lifted and lowered with the plug-in mechanism 1 and can be driven by the feeding mechanism 4 alone to move transversely.

[0051] In this embodiment, the pressing part 12 of the plug-in mechanism 1 is dynamically connected to the clamping mechanism 3 through the slide 30, so that the clamping mechanism 3 can be driven to rise and fall together. Therefore, when the plug-in is working, the clamping mechanism 3 can always hold the acid pot 10 and move downward. When the pressing part 12 moves up and resets, it drives the clamping mechanism 3 to move up and reset synchronously. The structural design of the synchronous vertical linkage of the clamping mechanism 3 driven by the pressing part 12 avoids the need to set up an additional driving part to drive the clamping mechanism 3 to cooperate with the plug-in action for synchronous action, and the method of setting up an additional driving part will also affect the battery feeding and cause feeding interference.

[0052] Embodiment 3 The same or corresponding components in this embodiment as those in the above-mentioned second embodiment are marked with the same reference numerals as those in the above-mentioned second embodiment. For the sake of simplicity, only the differences from the above-mentioned second embodiment are described below. The differences between this embodiment and the above-mentioned second embodiment are: As a preference, Figure 4 , 6 As shown, the plug-in drive part 11 includes: an upper cylinder 111 and a lower cylinder 112 which are distributed vertically, the upper cylinder 111 is vertically arranged and its driving end is connected to the frame upward, the lower cylinder 112 is vertically arranged and its driving end is connected to the pressing part 12 downward, and the other ends of the upper cylinder 111 and the lower cylinder 112 relative to their respective driving ends are connected to each other.

[0053] In this embodiment, the plug-in drive part 11 is vertically arranged by an upper cylinder 111 and a lower cylinder 112, and the two cylinders are arranged back to back to form a "two cylinders and three strokes" structure. The first stroke is to press the acid pot 10 downward through the pressing part 12, so that the spout structure 101 is guided to be inserted into the funnel-shaped positioning hole 21 for alignment. The second stroke is that after the left positioning part 221 and the right positioning part 222 are opened to make way, the pressing part 12 further presses down the positioned acid pot 10 to complete the complete connection between the acid pot 10 and the battery 20. The third stroke is for the mechanism to move up and reset.

[0054] Embodiment 4 The same or corresponding components in this embodiment as those in the above-mentioned second embodiment are marked with the same reference numerals as those in the above-mentioned second embodiment. For the sake of simplicity, only the differences from the above-mentioned second embodiment are described below. The differences between this embodiment and the above-mentioned second embodiment are: As a preference, Figure 6 As shown, the clamping mechanism 3 includes: a left clamping jaw 31 and a right clamping jaw 32, which are arranged to move relative to each other to perform a clamping action; and a clamping drive unit 33, which is drivingly connected to the left clamping jaw 31 and the right clamping jaw 32 to drive the left clamping jaw 31 and the right clamping jaw 32 to slide horizontally toward or away from each other.

[0055] Preferably, as Fig.10 shown, the clamping part of the left clamping jaw 31 is arranged in an "L" shape or a "冖" shape, so as to limit and clamp at least two sides of the acid pot 10, and the right clamping jaw 32 is arranged in a mirror image structure with the left clamping jaw 31.

[0056] In this embodiment, the acid pot 10 is positioned and clamped by being wrapped on four sides by the clamping mechanism 3, so that the acid pot 10 can be corrected and positioned, and guided and positioned, so that the acid pot 10 can be quickly and accurately inserted and matched with the storage battery 20 subsequently, and the matching efficiency is high.

[0057] Embodiment Five In this embodiment, the same or corresponding components as those in the second embodiment above adopt the corresponding reference numerals in the second embodiment above. For the sake of simplicity, only the differences from the second embodiment above will be described below. The difference between this embodiment and the second embodiment above is that: Preferably, as Figure 1 , 3 shown, the first conveying module includes: a first conveying line 5, a first conveying mechanism 6 and a feeding mechanism 7. The upright acid pots 10 are continuously conveyed on the first conveying line 5. The first conveying mechanism 6 pushes and distributes the acid pots 10 one by one to the side. The next acid pot 10 receiving the side push and distribution further pushes the previously distributed acid pot 10 onto the feeding mechanism 7, and the feeding mechanism 7 flips the acid pot 10 to an inverted state.

[0058] Preferably, as Figure 2-Figure 3 shown, the second conveying module includes: a second conveying line 8 and a second conveying mechanism 9. The storage batteries 20 are continuously conveyed on the second conveying line 8. The second conveying mechanism 9 pushes and distributes the storage batteries 20 one by one to the side. The next storage battery 20 receiving the side push and distribution further pushes the previously distributed storage battery 20 under the positioning mechanism 2.

[0059] In this embodiment, the feeding of the acid pot 10 and the storage battery 20 realizes double-station feeding, improves the continuous feeding efficiency, and avoids the long pushing stroke, long feeding time and low efficiency of single-station feeding.

[0060] Preferably, the clamping mechanism 3 is arranged to move up and down to cooperate with receiving the acid pot 10 fed by the feeding mechanism 7.

[0061] Preferably, as Figure 5 shown, the first conveying mechanism 6 includes: a pushing driving part 61, and the pushing driving part 61 is installed on the rack; and a buffer loading table 62. The push plate 610 of the pushing driving part 61 pushes the continuously conveyed acid pots 10 one by one onto the buffer loading table 62 for feeding, and the next acid pot 10 to be fed further pushes the acid pot 10 on the buffer loading table 62 onto the feeding mechanism 7.

[0062] As a preference, Fig.11 As shown, the feeding mechanism 7 is arranged horizontally opposite to the first conveying mechanism 6, and includes: a rotating driving part 71, which is installed on the frame; and a feeding clamping part 72, which receives and clamps the acid pot 10 in an upright state for feeding, and is driven by the rotating driving part 71 to rotate so as to flip the acid pot 10 to an inverted state.

[0063] Preferably, a material guiding slope 73 is provided at the lower portion of the feeding end of the feeding clamping portion 72, and trumpet-shaped material guiding openings 74 are formed at both sides of the feeding end.

[0064] In this embodiment, a material guide slope 73 is provided at the lower part of the feeding end of the feeding clamping part 72 of the feeding mechanism 7, and trumpet-shaped material guide openings 74 are formed on both sides to guide the feeding, thereby ensuring that the acid pot 10 can be smoothly pushed to the supporting platform of the feeding clamping part 72, thereby improving the feeding stability and feeding efficiency.

[0065] Embodiment 6 The same or corresponding components in this embodiment as those in the above-mentioned second embodiment are marked with the same reference numerals as those in the above-mentioned second embodiment. For the sake of simplicity, only the differences from the above-mentioned second embodiment are described below. The differences between this embodiment and the above-mentioned second embodiment are: As a preference, Figure 4 As shown, the acid pot 10 is provided with a spout structure 101 for discharging acid liquid. Figure 7 As shown, the battery 20 has an acid filling port 201 , the spout structure 101 corresponds to the acid filling port 201 one by one, and the spout structure 101 is plugged and installed in the acid filling port 201 , and the two cooperate to perform the acid filling operation.

[0066] As a preference, Fig. 9 As shown, the spout structure 101 includes: a spout 102, which is connected to the kettle body 103 of the acid kettle 10; and a guide part 104, which is arranged in a needle shape and inserted into the spout 102, and one end of which extends into the kettle body 103 and the other end extends out of the spout 102, and guides the acid liquid output.

[0067] It should be noted that the conventional acid kettle 10 only has an open spout 102. This structure lacks guidance when the acid liquid is discharged, resulting in poor discharge or leakage. However, the present embodiment improves the design of the spout structure 101 and inserts a needle-shaped guide part 104 in the spout 102 to play a guiding role, so that the acid liquid can flow out more smoothly and avoid poor discharge or leakage.

[0068] The acid pot 10 without the guide part 104 is easier to plug into the battery 20, but it is inconvenient to plug into the acid pot 10 with the guide part 104. If the guide part 104 is skewed, it will be difficult to align with the acid filling port 201 on the battery 20, so it is more necessary to perform a guiding operation before plugging.

[0069] Working process: The first conveyor line 5 continuously transmits the upright acid pot 10 to the first conveyor mechanism 6, and the first conveyor mechanism 6 pushes the acid pot 10 to one side one by one to distribute the materials, and the next acid pot 10 that receives the side push distribution further pushes the previous acid pot 10 to the feeding mechanism 7, and the feeding mechanism 7 flips the acid pot 10 to an inverted state. After the clamping mechanism 3 clamps the acid pot 10 fed by the feeding mechanism 7, the feeding mechanism 4 drives the clamping mechanism 3 to move horizontally to push the acid pot 10 to the bottom of the plug-in mechanism 1; at the same time, the second conveyor line 8 continuously transmits the storage battery 20 to the second conveyor mechanism 9, and the second conveyor mechanism 9 pushes the storage battery 20 to one side one by one to distribute the materials, and the next storage battery 20 that receives the side push distribution further pushes the previous storage battery 20 to the bottom of the positioning mechanism 2 to wait for the plug-in work; The plug-in mechanism 1 first presses down the acid pot 10 loaded in place below it in one stage, so that its spout structure 101 is guided and inserted into the positioning hole 21 of the positioning mechanism 2 to calibrate the possible skewness, and then the positioning mechanism 2 is moved away to make way, and the plug-in mechanism 1 further presses down the acid pot 10 in a second stage, so that the acid pot 10 and the battery 20 are matched and plugged in place. In this process, the clamping mechanism 3 and the plug-in mechanism 1 move vertically, so as to maintain the positioning and clamping of the acid pot; After the plugging work is completed, the mechanism is reset and the storage battery 20 equipped with the acid pot 10 flows out.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
