Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of lead-acid battery acid adding technical field, specifically to a kind of acid adding head. BACKGROUND

[0002] The application field of storage battery is very extensive. In the manufacturing process of storage battery, especially in the acid adding process, it is necessary to add acid to the storage battery in a rich liquid manner to ensure sufficient electrochemical reaction. Usually, an acid adding kettle is first sleeved on the acid adding hole of the middle cover, and then machine acid adding is performed.

[0003] The patent document with the authorized announcement number CN105244469B discloses a kind of storage battery acid adding device. When used, acid liquid enters the acid adding kettle from acid adding hose and acid adding pipe, and then enters the storage battery from the acid adding hole. The acid adding pressure plate presses the sealing gasket, so that the conical boss on the upper end edge of the kettle body of the acid adding kettle is tightly matched with the sealing gasket, and the rubber nozzle is matched with the groove around the acid adding hole on the middle cover. The sealing property is good during acid adding, so that the acid liquid can enter the bottom of the battery. When cleaning is needed, the acid adding pressure plate is removed, and the tool can be inserted into the kettle body of the acid adding kettle for cleaning, so that the deteriorated colloid can be easily washed out. During the acid adding process of lead-acid battery, the acid adding kettle is inserted into the acid adding hole of the lead-acid battery in advance. In order to add acid to the acid kettle, the upper end opening of the acid kettle is relatively large, and the acid liquid in the acid kettle is easy to spill during the subsequent movement of the battery.

[0004] The patent document with the publication number CN211455830U discloses an automatic acid adding machine feeding device. When feeding, the battery shell to be added with acid is manually placed on the limiting device, and the automatic acid adding head corresponds to the battery shell below it. The upper telescopic cylinder is started, the automatic acid adding head is lowered and buckled on the battery shell below it, and then the acid adding operation is performed. After the acid adding is completed, the automatic acid adding head is restored, and the battery shell to be added with acid is placed one by one on the first conveying belt. The blocking device on the first conveying belt intercepts the battery shell on the first conveying belt in turn. At this time, the battery shell on the first conveying belt corresponds to the battery shell with acid added in the limiting device. The telescopic rod of the rear telescopic cylinder extends to the first conveying belt direction, and the stop rod moves. Then the telescopic rod of the front telescopic cylinder extends and moves to the second conveying belt direction. The push rod pushes the battery shell on the first conveying belt to the limiting device. After the battery shell on the first conveying belt is pushed into the limiting device, the battery with acid added in the limiting device is pushed to the second conveying belt and contacts the stop rod. At this time, the battery shell in the limiting device below the automatic acid adding head corresponds to the automatic acid adding head. Under the blocking action of the stop rod, when the push rod pushes the battery shell on the first conveying belt, the battery shell moves too far due to its own inertia, so that the automatic acid adding head does not correspond to the battery shell below it, which causes the acid to run during the acid adding process. After the battery shell on the first conveying belt is pushed to the limiting device, the telescopic rod of the front telescopic cylinder and the push rod are restored. Because the opening of the existing acid pot for storage battery is small, in order to effectively add acid to the battery and prevent acid running, the device sets a mechanism for clamping and positioning the battery so that the battery corresponds to the acid adding head. When the mechanism for clamping and positioning the battery fails, acid running may still occur. Therefore, the structure of the acid adding head needs to be improved to ensure that acid running does not occur when the mechanism for clamping and positioning the battery fails.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0020] Embodiment one: refer to Figures 1-3 As shown in the figure, an acid adding head, comprising an upper shell 1, the upper shell 1 upper end is fixed with ear plate 8 and inlet pipe 7, ear plate 8 is connected with lifting assembly, inlet pipe 7 is communicated with quantitative pump through hose.

[0021] The upper shell 1 lower end is fixed with fixed ring 3, the fixed ring 3 lower end is 90 degrees bent to its axial direction and forms a bent part, the fixed ring 3 part above the bent part is vertical part.

[0022] The fixed ring 3 is provided with lower shell 2, the lower shell 2 upper end is slidingly and sealingly connected with the lower end of the upper shell 1, the lower shell 2 upper end is provided with lower hole 11, the lower end of the upper shell 1 is provided with upper hole 10 concentric with lower hole 11, and upper hole 10 is communicated with lower hole 11.

[0023] The lower shell 2 outer edge and the bent part of the fixed ring 3 are provided with a gap, the lower shell 2 outer edge inside the fixed ring 3 is fixed with ring plate 4, and the lower end of the ring plate 4 is in sliding contact with the upper end of the bent part of the fixed ring 3. The ring plate 4 and the vertical part of the fixed ring 3 are connected by a plurality of springs 9, and the plurality of springs 9 are arranged according to the circumference of the axis of the lower shell 2.

[0024] The lower shell 2 lower end is fixedly communicated with a plurality of acid pipes 6.

[0025] The lower shell 2 lower end is fixed with guide plate 5, the lower part of the guide plate 5 is bent to the outside of the lower shell 2, and the upper part of the guide plate 5 is vertically arranged.

[0026] The lower shell 2 upper end is fixed with sealing gasket 12, the lower shell 2 upper end and the lower end of the upper shell 1 are slidingly and sealingly connected through sealing gasket 12, the sealing gasket 12 is provided with through hole 13, and the through hole 13 communicates upper hole 10 and lower hole 11. The diameter of the upper hole 10 is greater than the diameter of the lower hole 11.

[0027] After the battery is clamped and positioned by the clamping and positioning mechanism, the lifting assembly drives the acid filling head downwards. When the battery is accurately clamped and positioned by the clamping and positioning mechanism, the lower shell 2 and the upper shell 1 do not move relative to each other during the downward movement of the acid filling head. After the acid tube 6 is inserted into the acid filling port at the top of the acid reservoir, the upper part of the guide plate 5 contacts the outside of the battery. The metering pump is started, and the metering pump adds a metered amount of acid into the acid reservoir through the upper shell 1, the lower shell 2, and the acid tube 6, thus completing the acid filling process for the battery.

[0028] When the battery is not accurately positioned by the clamping and positioning mechanism, during the downward movement of the acid filling head, after the lower part of the guide plate 5 contacts the battery, the lower shell 2 and the ring plate 4 move within the fixed ring 3 under the guidance of the lower part of the guide plate 5. The spring 9 deforms. When the upper part of the guide plate 5 contacts the outside of the battery, the lower shell 2 and the ring plate 4 stop moving within the fixed ring 3. At this time, the acid tube 6 corresponds to the acid filling port at the upper end of the acid reservoir on the battery. Subsequently, during the continued downward movement of the acid filling head, the acid tube 6 can be accurately inserted into the acid filling port of the acid reservoir, thereby avoiding acid leakage during the acid filling process. Since the diameter of the upper hole 10 is larger than the diameter of the lower hole 11, when the lower shell 2 and the ring plate 4 move within the fixed ring 3, the upper shell 1 and the lower shell 2 can remain in communication.

[0029] After adding acid to batteries that were not accurately clamped and positioned, the acid-adding head moves upward and returns to its original position. Under the elastic force of spring 9, the lower shell 2 can return to its original position, making it convenient to add acid to batteries that are accurately positioned later.

[0030] Example 2: Based on Example 1, referring to... Figure 1 As shown, the lower end of the acid tube 6 is a pointed tip, which facilitates the insertion of the acid tube 6 into the acid filling port at the upper end of the acid pot.

[0031] 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.
