This invention uses the first conveyor belt to convey the acid-adding kettle, the second conveyor belt to convey the storage battery, then the clamp picks up the acid-adding kettle and places it on the storage battery, and finally the pressure plate presses the acid-adding kettle down to insert the acid-adding nozzle into the storage battery's acid-adding hole, thus automatically assembling the acid-adding kettle onto the storage battery.

[0004] However, in existing technical solutions, if there is a misalignment in the fit between the acid reservoir and the battery, it will lead to difficulties in insertion and failure to insert effectively. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a battery acid injection device. This device achieves multi-stroke action through a single drive of the insertion mechanism, thereby completing actions such as positioning and calibration of the acid reservoir spout structure, alignment and insertion with the battery, and self-reset. This solves the technical problems in existing technologies, such as difficulty in insertion and inability to effectively insert the acid reservoir into place if there is a deviation in the matching position between the acid reservoir and the battery.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A battery acid filling device includes: a clamping mechanism for holding an inverted acid reservoir; a positioning mechanism located below the clamping mechanism for positioning and calibrating the spout structure of the acid reservoir; a battery located below the positioning mechanism, wherein the spout structure, after calibration, is aligned and inserted into the acid filling port on the battery; and an insertion mechanism for pressing the acid reservoir down in sections from above the clamping mechanism, thereby first cooperating with the positioning mechanism to calibrate the spout structure and then inserting the acid reservoir into the battery.

[0008] Preferably, there is a height difference between the plug-in mechanism and the acid pot.

[0009] Preferably, the insertion mechanism includes: an insertion drive portion, which is vertically mounted on the frame and provides segmented vertical driving force; and a pressing portion, which is mounted on the bottom drive end of the insertion drive portion to be driven by the insertion drive portion to move up and down.

[0010] Preferably, the plug-in drive part includes: an upper cylinder and a lower cylinder arranged vertically. The upper cylinder is arranged vertically and its drive end faces upward and is connected to the frame. The lower cylinder is arranged vertically and its drive end faces downward and is connected to the pressing part. The other ends of the upper cylinder and the lower cylinder are connected to each other relative to their respective drive ends.

[0011] Preferably, the upper cylinder and the lower cylinder are connected to each other at the other end of their respective drive ends, thereby forming a back-to-back structure.

[0012] Preferably, the clamping mechanism is vertically adjustable to move the acid pot down in stages in sync with the acid pot, thereby maintaining the holding and positioning of the acid pot during calibration and insertion.

[0013] Preferably, the clamping mechanism is vertically slidably installed and is poweredly connected to the drive end of the plug-in mechanism, so that it is driven by the plug-in mechanism to move synchronously.

[0014] As an alternative embodiment, an additional lifting drive mechanism may be included, which drives the clamping mechanism to move vertically up and down.

[0015] Preferably, the positioning mechanism is located directly below the insertion mechanism, and includes: a positioning component with positioning holes, the positioning holes being configured one-to-one with the spout structure, the positioning holes being configured as an inverted cone shape with a larger upper part and a smaller lower part, thereby gradually guiding the spout structure to the correct position if it may become misaligned; and a positioning drive unit, the positioning drive unit driving the positioning component to move, thereby making way for the insertion operation.

[0016] Preferably, the positioning component includes a left positioning part and a right positioning part with a mirror-symmetrical structure, which are arranged to move relative to each other and are joined together to form the positioning hole when they are closed. The positioning driving part is driven to be connected to the left and right positioning parts to drive the left and right positioning parts to close or open.

[0017] Preferably, the device further includes: a feeding mechanism, which is arranged horizontally side by side with the insertion mechanism and is located above the clamping mechanism, and feeds acid jugs to the clamping mechanism; and a pushing mechanism, which is mounted on the frame and drives the clamping mechanism to move laterally to push the clamping mechanism directly below the insertion mechanism or reset the clamping mechanism directly below the feeding mechanism.

[0018] As a supplementary explanation, the clamping mechanism is vertically slidably mounted on the horizontal slide of the pushing mechanism, so that the clamping mechanism is driven by the horizontal slide to move laterally. At the same time, the clamping mechanism can also move vertically with the insertion mechanism.

[0019] Preferably, the clamping mechanism and the insertion mechanism are connected by a slide table. The slide table is fixedly installed on the drive seat of the clamping mechanism. A long groove is opened laterally on the slide table. One end of the pressing part of the insertion mechanism is slidably installed in the long groove by a roller.

[0020] Thus, the clamping mechanism can be driven to move laterally by the pushing mechanism, and at the same time, the clamping mechanism can also move vertically with the insertion mechanism.

[0021] Preferably, the clamping mechanism includes: a left clamp and a right clamp, which are arranged to move relative to each other to perform clamping actions; and a clamping drive unit, which is driven to connect with the left and right clamps to drive the left and right clamps to close or open.

[0022] Preferably, the spout structure includes: a spout connected to the body of the acid pot; and a flow guide, which is needle-shaped and inserted into the spout, with one end extending into the pot body and the other end extending out of the spout, for guiding the output of acid.

[0023] Preferably, the acid dispenser is provided with a spout structure for dispensing acid, and the battery has an acid filling port. The spout structure corresponds one-to-one with the acid filling port, and the spout structure is inserted into the acid filling port. The two work together to perform acid filling.

[0024] The beneficial effects of this utility model are as follows:

[0025] (1) This utility model achieves multi-stroke action through single drive of the plug-in mechanism, thereby completing the positioning and calibration of the acid pot spout structure, alignment and plugging with the storage battery, and self-reset. Through the plug-in mechanism, clamping mechanism, positioning mechanism and storage battery arranged from top to bottom, the plug-in mechanism drives the acid pot to move down to plug with the storage battery. During the plugging process, the clamping mechanism always positions and holds the inverted acid pot. Before plugging, the positioning mechanism guides the spout structure to the correct position if it may be skewed. This ensures that the acid pot can quickly and accurately cooperate with the storage battery and effectively plug in. The cooperation efficiency is high, the structure design is compact and ingenious and the working efficiency is high.

[0026] (2) In this utility model, a small height difference is set between the acid pot and the plug-in mechanism. The function is that when the plug-in mechanism presses down on the acid pot, due to the height difference, that is, the two are not rigidly abutting, but there is a certain pressure buffer and elastic rebound, so that the guide part of the spout structure can automatically correct the slight skew that may occur.

[0027] (3) In this utility model, the drive part of the plug-in mechanism is provided by two cylinders arranged vertically, one above the other, with the two cylinders arranged back to back, forming a structure of "two cylinders and three strokes". The first stroke is to press down the acid pot through the pressing part, so that the spout structure is guided to be inserted into the funnel-shaped positioning hole for proper positioning. The second stroke is after the left and right positioning parts open to make room, the pressing part further presses down the positioned acid pot to complete the complete plug-in of the acid pot and the storage battery. The third stroke is for the mechanism to move up and reset.

[0028] (4) The present invention connects the pressing part to the acid pot clamping mechanism via the slide table, thereby enabling the clamping mechanism to move up and down together. When the insertion is performed, the clamping mechanism can always hold the acid pot and move down. When the pressing part moves up and resets, it drives the clamping mechanism to move up and reset synchronously. Thus, the structure design of the pressing part driving the clamping mechanism to move up and reset synchronously avoids the need to set up a separate drive part to drive the clamping mechanism to move synchronously with the insertion action. In addition, the method of setting up a separate drive part will affect the battery feeding and cause feeding interference.

[0029] (5) In the process of inserting the acid pot by moving it down, the spout structure of the present invention first inserts into the positioning hole of the positioning mechanism to obtain the positioning calibration operation before insertion. The positioning hole is set as an inverted cone shape, which can provide main compensation for the possible skewness of the guide part and guide it to the correct position, thereby ensuring that the guide part can be quickly and smoothly aligned when it is subsequently inserted into the acid port.

[0030] (6) This utility model improves the design of the spout structure of the acid adding pot by inserting a needle-shaped guide part into the spout to guide the flow, making the acid flow out more smoothly and avoiding problems of poor liquid flow or leakage. Attached Figure Description

[0040] Example 1

[0041] like Figure 1-3 As shown, a battery acid filling device includes: a clamping mechanism 1, which holds an inverted acid reservoir 2; a positioning mechanism 3, located below the clamping mechanism 1, which positions and calibrates the spout structure 20 of the acid reservoir 2; a battery 4, located below the positioning mechanism 3, which aligns and inserts the calibrated spout structure 20 with the acid filling port 40 on the battery 4; and a connection mechanism 5, which presses down the acid reservoir 2 in sections from above the clamping mechanism 1, thereby first cooperating with the positioning mechanism 3 to complete the calibration of the spout structure 20, and then completing the connection between the acid reservoir 2 and the battery 4.

[0042] In this embodiment, the single drive of the insertion mechanism 5 realizes multi-stroke action, thereby completing the positioning and calibration of the spout structure 20 of the acid pot 2, the alignment and insertion with the battery 4, and the self-reset. Through the insertion mechanism 5, clamping mechanism 1, positioning mechanism 3 and battery 4 arranged sequentially from top to bottom, the insertion mechanism 5 drives the acid pot 2 to move down to insert with the battery 4. During the insertion process, the clamping mechanism 1 always positions and holds the inverted acid pot 2, and before insertion, the positioning mechanism 3 guides the spout structure 20 to correct any possible misalignment, thereby ensuring that the acid pot 2 can quickly and accurately cooperate and effectively insert with the battery 4. The cooperation efficiency is high, the structural design is compact and ingenious, and the working efficiency is high.

[0043] Preferably, there is a height difference between the plug-in mechanism 5 and the acid pot 2.

[0044] In this embodiment, by setting a height difference between the bottom of the acid pot 2 and the insertion mechanism 5, the purpose is that when the insertion mechanism 5 presses down on the acid pot 2, due to the small height difference between the acid pot 2 and the insertion mechanism 5, that is, the two are not rigidly abutting, but there is a certain pressure buffer and elastic rebound. Thus, the guide part 23 of the spout structure 20 can automatically correct any possible slight misalignment. If the acid pot 2 and the insertion mechanism 5 are rigidly abutting from the beginning, then if the guide part 23 is misaligned, it will be pressed down more and more firmly in a misaligned state, making it difficult to achieve the correction effect or even causing the guide part 23 to be damaged.

[0045] As a supplementary note, a slight height difference is provided between the bottom of the acid pot 10 and the bottom of the insertion mechanism 5.

[0046] As a preferred option, such as Figure 4As shown, the insertion mechanism 5 includes: an insertion drive portion 50, which is vertically mounted on the frame and provides segmented vertical driving force; and a pressing portion 51, which is mounted on the bottom drive end of the insertion drive portion 50 to be driven by the insertion drive portion 50 to move up and down.

[0047] Preferably, the acid pot 2 is provided with a spout structure 20 for dispensing acid, and the battery 4 is provided with an acid filling port 40. The spout structure 20 and the acid filling port 40 correspond one-to-one and the spout structure 20 is inserted into the acid filling port 40. The two work together to perform acid filling.

[0048] As a preferred option, such as Figure 3 As shown, the positioning mechanism 3 is located directly below the insertion mechanism 5, and it includes: a positioning component 31, which is combined with... Figure 5 As shown, the positioning component 31 has a positioning hole 30, which corresponds to the spout structure 20. The positioning hole 30 is set in an inverted cone shape that is larger at the top and smaller at the bottom, so as to gradually guide the spout structure 20 to be in the correct position if it may be misaligned. There is also a positioning drive unit 32, which drives the positioning component 31 to move, so as to make way for the insertion work.

[0049] In this embodiment, during the insertion process by moving the acid pot 2 downward, its spout structure 20 first inserts into the positioning hole 30 of the positioning mechanism 3 to obtain the positioning calibration operation before insertion. The positioning hole 30 is set as an inverted cone shape, which can provide main compensation and guidance to correct the possible skewness of the spout structure 20, especially the guide part 23, thereby ensuring that it can be quickly and smoothly aligned when inserted into the acid filling port 40 in the subsequent process.

[0050] Preferably, the positioning component 31 includes a left positioning part 311 and a right positioning part 312 with a mirror-symmetrical structure. The two parts are arranged to move relative to each other and are joined together to form the positioning hole 30 when they are closed. The positioning driving part 32 is drivenly connected to the left positioning part 311 and the right positioning part 312 to drive the left positioning part 311 and the right positioning part 312 to close or open.

[0051] In this embodiment, after the positioning is completed before insertion, the left positioning part 311 and the right positioning part 312 open to make room and avoid interference, so that the spout structure 20 moves further down to align with the acid filling port 40 of the battery 4 for insertion.

[0052] As a preferred option, such as Figure 4 , 7As shown, the clamping mechanism 1 includes: a left clamping jaw 11 and a right clamping jaw 12, which are arranged to move relative to each other to perform clamping actions; and a clamping drive unit 13, which is drivenly connected to the left clamping jaw 11 and the right clamping jaw 12 to drive the left clamping jaw 11 and the right clamping jaw 12 to close or open.

[0053] Preferably, the spout structure 20 includes: a spout 21, which is connected to the body 22 of the acid pot 2; and a flow guide 23, which is needle-shaped and inserted into the spout 21, with one end extending into the body 22 and the other end extending out of the spout 21, and guides the output of acid liquid.

[0054] It should be noted that conventional acid jugs 2 only have an open spout 21. This structure lacks flow guidance when acid is dispensed, resulting in poor flow or leakage. In this embodiment, the spout structure 20 is improved by inserting a needle-shaped flow guide 23 into the spout 21 to guide the flow and make the acid flow out more smoothly.

[0055] Acid dispenser without a flow guide is easier to connect to the battery, while one with a flow guide 23 is more difficult to connect. If the flow guide 23 is misaligned, it will be difficult to align with the acid filling port 40 on the battery 4. Therefore, a guiding operation is more necessary before connection. The positioning operation of the acid dispenser before connection in this embodiment is particularly applicable.

[0056] Example 2

[0057] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0058] As a preferred option, such as Figure 7 As shown, the plug-in drive part 50 includes an upper cylinder 52 and a lower cylinder 53 arranged vertically. The upper cylinder 52 is arranged vertically and its drive end faces upward and is connected to the frame. The lower cylinder 53 is arranged vertically and its drive end faces downward and is connected to the pressing part 51. The other ends of the upper cylinder 52 and the lower cylinder 53 are connected to each other relative to their respective drive ends.

[0059] In this embodiment, the insertion drive part 50 is configured with an upper cylinder 52 and a lower cylinder 53 arranged vertically and back to back, forming a "two cylinders, three strokes" structure. The first stroke is when the pressing part 51 presses down on the acid pot 2, so that the spout structure 20 is guided to be inserted into the funnel-shaped positioning hole 30 for proper positioning. The second stroke is when the left positioning part 311 and the right positioning part 312 open to make room, and the pressing part 51 further presses down on the positioned acid pot 2 to complete the full insertion of the acid pot 2 and the battery 4. The third stroke is when the mechanism moves upward to reset.

[0060] Preferably, the upper cylinder 52 and the lower cylinder 53 are connected to each other at the other end of their respective drive ends, thereby forming a back-to-back structure.

[0061] Example 3

[0062] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0063] As a preferred option, such as Figure 7 As shown, the clamping mechanism 1 is vertically raised and lowered to coordinate with the acid pot 2 to move down in segments, thereby maintaining the holding and positioning of the acid pot 2 during calibration and insertion.

[0064] Preferably, the clamping mechanism 1 is vertically slidably installed and is poweredly connected to the drive end of the plugging mechanism 5, so that it is driven by the plugging mechanism 5 to move synchronously.

[0065] As a parallel embodiment, an additional lifting drive mechanism may be included, which drives the clamping mechanism 1 to move vertically up and down.

[0066] Example 4

[0067] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0068] As a preferred option, such as Figure 2 As shown, it also includes: a feeding mechanism 6, which is arranged horizontally side by side with the insertion mechanism 5 and is located above the clamping mechanism 1, and feeds the acid pot 2 to the clamping mechanism 1; and a pushing mechanism 7, which is mounted on the frame and drives the clamping mechanism 1 to move laterally, so as to push the clamping mechanism 1 directly below the insertion mechanism 5 or reset the clamping mechanism 1 directly below the feeding mechanism 6.

[0069] As a supplementary explanation, such as Figure 6-7 As shown, the clamping mechanism 1 is vertically slidably mounted on the horizontal slide 71 of the pushing mechanism 7, so that the clamping mechanism 1 is driven by the horizontal slide 71 to move laterally. At the same time, the clamping mechanism 1 can also move vertically with the insertion mechanism 5.

[0070] Preferably, the clamping mechanism 1 and the insertion mechanism 5 are connected by a slide table 8. The slide table 8 is fixedly installed on the drive seat of the clamping mechanism 1. A long groove 81 is opened laterally on the slide table 8. One end of the pressing part 51 of the insertion mechanism 5 is slidably installed in the long groove 81 by a roller.

[0071] Thus, the clamping mechanism 1 can be driven by the pushing mechanism 7 to move laterally, and at the same time, the clamping mechanism 1 can also move vertically with the insertion mechanism 5.

[0072] In this embodiment, the pressing part 51 is poweredly connected to the clamping mechanism 1 via the slide table 8, thereby driving the clamping mechanism 1 to move up and down together. When the insertion operation is performed, the clamping mechanism 1 can always hold the acid pot 2 and move it down. When the pressing part 51 moves up and resets, it drives the clamping mechanism 1 to move up and reset synchronously. Thus, the structural design of the pressing part 51 driving the clamping mechanism 1 in a synchronous linkage avoids the need to set up an additional drive part to drive the clamping mechanism 1 to coordinate with the insertion operation. In addition, the method of setting up an additional drive part will also affect the battery feeding and cause feeding interference.

[0073] Work process:

[0074] The feeding mechanism 6 feeds the acid pot 2 to the clamping mechanism 1. After the clamping mechanism 1 clamps the acid pot 2, the pushing mechanism 7 drives the clamping mechanism 1 to move laterally to push the clamping mechanism 1 directly below the insertion mechanism 5. The insertion mechanism 5 drives the clamping mechanism 1 and the acid pot 2 on it to move down. The spout structure 20 is guided to be inserted into the positioning hole 30 of the positioning mechanism 3 for calibration. Then the positioning component 31 makes way, and the insertion mechanism 5 drives the clamping mechanism 1 and the acid pot 2 on it to move down further so that the spout structure 20 is inserted into the acid filling port 40 of the battery 4. After the insertion is completed, the mechanism resets, and the battery 4 equipped with the acid pot 2 flows out.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
