Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery repair technology, specifically to a battery repair auxiliary device. Background Technology

[0002] The structure of a lead-acid battery includes a casing, plates, separators, and a middle cover. The middle cover usually has a busbar groove and a glue groove. For example, patent application number 200620170736.4 discloses a new type of valve-regulated sealed lead-acid battery casing, including an upper cover and a lower cover. The upper cover has ventilation holes and a glue groove on its inner wall. The lower cover contains a group of terminals and separators. The upper cover of this lead-acid battery is fixed to the lower cover by glue in the glue groove.

[0003] During the manufacturing and installation of lead-acid batteries, especially in the sealing process, manual sealing can easily lead to defective products, such as gaps in the middle cover, air leakage, and internal cell misalignment. Such lead-acid batteries need to be resealed and repaired.

[0004] The current method of opening the cover involves manually using an electric heat gun to heat-melt the middle cover and each glue seal point. The temperature usually needs to reach above 140 degrees Celsius to melt the glue, so that the middle cover can be peeled off. This is time-consuming and laborious. If the heat-melting time is too short, the temperature is too low, or a glue seal point is missed or the heat-melting of the glue seal point is uneven, it is easy to cause damage to the battery case and busbar when opening the cover.

[0005] To address the aforementioned technical problems, patent document CN212136627U discloses an auxiliary cover-opening device for battery repair. The device includes a hot air box with an open bottom and a wind distribution plate located on the bottom of the hot air box. The wind distribution plate has ventilation holes corresponding to the positions of the adhesive grooves on the battery cover during use. The hot air box has mounting holes for installing a hot air system. The hot air generated by the hot air system can rapidly and precisely heat the adhesive in the adhesive groove through the ventilation holes in the hot air box and the wind distribution plate, thereby accelerating the thermal melting of the adhesive in the groove.

[0006] To ensure the connection strength and sealing performance between the battery cover and the battery compartment, some existing batteries have adhesive grooves at the joint between the battery cover and the battery compartment. During use, when hot air flows through the exhaust gaps, it can only melt the adhesive in the groove corresponding to the exhaust interval. The adhesive in the groove corresponding to the positioning boss has a low degree of melting, resulting in high resistance when opening the battery cover. If the hot air heating time is increased to completely melt the adhesive in the groove between the battery cover and the battery compartment, the temperature at the top of the battery cover will be too high, which can easily damage the battery cover and the busbar. In some batteries, the battery cover portion above the adhesive groove that accommodates the upper part of the battery compartment is relatively thick, and the efficiency of melting the adhesive in the groove bonded to the battery compartment when hot air blows directly from top to bottom is low. Utility Model Content

[0007] The main purpose of this utility model is to provide a battery repair auxiliary device that enables the adhesive in the groove between the battery cover and the battery compartment to melt quickly, making it easier to open the battery cover and thus improving the repair efficiency.

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0009] A battery repair auxiliary device is provided. The battery includes a battery case and a battery cover that cover each other. The battery case is divided into multiple cells by a partition plate. Each cell contains a group of electrodes. Adjacent groups of electrodes are connected in series by a busbar. The back of the battery cover is provided with a glue groove. The glue groove includes three types that correspond to the top surface of the side wall of the battery case, the partition plate and the busbar respectively.

[0010] The repair auxiliary device includes a housing with an opening at the lower end and a wind distribution plate located inside the lower end of the housing. The wind distribution plate has ventilation holes corresponding to the positions of the rubber grooves on the battery cover. The housing has mounting holes for installing a hot air system. A rectangular frame-shaped inner ring is fixed inside the lower end of the housing. The inner edge of the inner ring has a groove. The upper end of the inner ring has an upper hole communicating with the groove. The outer side of the inner ring has an outlet hole communicating with the groove. The housing has a side hole communicating with the outlet hole. The joint between the battery cover and the battery compartment corresponds to the middle of the groove. The inner edge of the inner ring above the groove is in sealed contact with the outer edge of the battery cover. The inner edge of the inner ring below the groove is in sealed contact with the outer edge of the battery compartment.

[0011] Specifically, the inner ring has multiple threaded blind holes on its outer side, and the housing has through holes corresponding to the threaded blind holes. Screws pass through the through holes and are threadedly connected to the threaded blind holes.

[0012] Specifically, the outer edge of the inner ring is in sealed contact with the inner wall of the housing.

[0013] Specifically, the air distribution plate is fixed with multiple vertically arranged fixing columns, the lower end of the fixing columns is tightly abutting the upper end of the battery cover, and the upper end of the air distribution plate is fixed with multiple vertically arranged light rods, the upper end of the light rods penetrates through the upper end of the housing, and the light rods are slidably and sealingly connected to the upper end of the housing.

[0014] Specifically, an adjusting bolt is rotatably connected to the air distribution plate, the adjusting bolt passes through the upper end of the housing, and the adjusting bolt is threadedly connected to the upper end of the housing.

[0015] Specifically, there are two upper holes, located on the left and right sides of the inner ring respectively, and two outlet holes, located on the front and rear sides of the inner ring respectively.

[0016] Specifically, the hot air system is an electric heater or a hair dryer.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The device achieves dual-path flow of hot air through the ventilation holes in the air distribution plate and the annular groove structure of the inner ring. The hot air directly heats the adhesive tray of the battery cover through the ventilation holes while simultaneously circulating continuously within the annular groove. This ensures that heat evenly covers all areas of the adhesive tray, such as the reverse side of the battery cover, the top surface of the battery tray sidewalls, the adhesive trays corresponding to the partition plates and busbars, effectively and comprehensively melting the adhesive within the tray and avoiding adhesive residue problems caused by insufficient localized heating.

[0019] 2. Hot air flows within the annular groove, and the flow trajectory is as follows: Figure 4 As shown, the adhesive inside the groove at the joint between the battery cover and the battery compartment is continuously heated. This design significantly reduces the manual force required to open the battery cover, lowers the risk of damage to components such as the battery compartment, separator, or electrode group caused by prying operations, and makes the repair process easier and safer.

[0020] 3. The inner ring makes sealed contact with the outer edge of the battery cover, the outer edge of the battery slot, and the inner wall of the casing, ensuring no hot air leakage and concentrating heat in the target adhesive area. Simultaneously, the linkage mechanism of adjusting bolts, guide rods, and fixing columns allows users to flexibly adjust the height of the air distribution plate, thereby precisely controlling the alignment of the ring slot with the battery joint. This not only improves the device's adaptability to batteries of different sizes but also optimizes the sealing effect, preventing heat waste.

[0021] 4. The hot air system is compatible with electric heat guns or hair dryers, simplifying equipment configuration. The height adjustment function of the air distribution plate allows users to quickly adapt to changes in battery height, reducing repair preparation time and supporting rapid deployment in various maintenance scenarios, enhancing the practicality and user-friendliness of the device.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1: A battery repair auxiliary device, the battery includes a battery compartment 2 and a battery cover 1 that cover each other. The battery compartment 2 is divided into multiple cells by a partition plate. Each cell contains a group of electrodes. Adjacent groups of electrodes are connected in series by a busbar. The back of the battery cover 1 is provided with a glue groove 11. The glue groove 11 includes three types that correspond to the top surface of the side wall of the battery compartment 2, the partition plate and the busbar respectively.

[0029] Reference Figures 1-4 As shown, the repair auxiliary device includes a housing 5 with an opening at the lower end and a wind distribution plate 3 located inside the lower end of the housing 5. The wind distribution plate 3 has ventilation holes 31 that correspond to the positions of the glue grooves 11 on the battery cover 1.

[0030] The housing 5 has mounting holes 52 for installing a hot air system. The hot air system is an electric heater or a hair dryer.

[0031] A rectangular inner ring 4 is fixed inside the lower end of the housing 5. Specifically, multiple threaded blind holes 44 are provided on the outer side of the inner ring 4, and through holes corresponding to the threaded blind holes 44 are provided on the housing 5. Screws 42 pass through the through holes and are threadedly connected to the threaded blind holes 44.

[0032] The inner ring 4 has an inner groove 41 on its inner edge, an upper hole 43 communicating with the groove 41 at the upper end of the inner ring 4, an outlet hole 45 communicating with the groove 41 on the outer side of the inner ring 4, and a side hole 51 communicating with the outlet hole 45 on the housing 5.

[0033] There are two upper holes 43, located on the left and right sides of the inner ring 4 respectively. There are two outlet holes 45, located on the front and rear sides of the inner ring 4 respectively.

[0034] The seam between the battery cover 1 and the battery slot 2 corresponds to the middle of the annular groove 41. The inner edge of the inner ring 4 above the annular groove 41 is in sealed contact with the outer edge of the battery cover 1. The inner edge of the inner ring 4 below the annular groove 41 is in sealed contact with the outer edge of the battery slot 2. The outer edge of the inner ring 4 is in sealed contact with the inner wall of the housing 5.

[0035] Install the outlet end of the hot air gun or hair dryer into the mounting hole 52, and then adjust the height of the housing 5 on the battery so that the seam between the battery cover 1 and the battery slot 2 aligns with the annular groove 41. Turn on the hot air gun or hair dryer; hot air enters the housing 5 and is blown towards the upper end of the battery cover 1 through the ventilation hole 31. The hot air passing through the ventilation hole 31 enters the annular groove 41 through the upper hole 43. After flowing within the annular groove 41, the hot air is discharged to the outside of the housing 5 through the outlet hole 45 and the side hole 51. The flow trajectory of the hot air within the annular groove 41 is as follows: Figure 4 As shown, Figure 4 The direction indicated by the middle shear head is the flow direction of hot air within the annular groove 41.

[0036] By continuously circulating hot air within the annular groove 41, the hot air in the annular groove 41 can effectively and comprehensively heat-melt the adhesive in the groove at the joint between the battery cover 1 and the battery compartment 2, as well as the adhesive in the groove that is bonded to the top surface of the side wall of the battery compartment 2. The hot air passing through the ventilation hole 31 can effectively heat-melt the adhesive in the groove inside the battery cover 1 that is bonded to the top surface of the side wall of the battery compartment 2, the partition plate, and the busbar. The adhesive in the groove that is bonded to the top surface of the side wall of the battery compartment 2 is heated by the hot air passing through the ventilation hole 31 and the hot air flowing within the annular groove 41, thereby ensuring that the battery cover 1 can be easily opened.

[0037] Example 2: Based on Example 1, referring to... Figure 2 As shown, multiple vertically arranged fixing posts 32 are fixed on the air distribution plate 3. The lower end of the fixing post 32 is tightly abutted against the upper end of the battery cover 1. Multiple vertically arranged light rods 34 are fixed on the upper end of the air distribution plate 3. The upper end of the light rods 34 penetrates through the upper end of the housing 5, and the light rods 34 are slidably and sealingly connected to the upper end of the housing 5. An adjusting bolt 33 is rotatably connected to the air distribution plate 3. The adjusting bolt 33 penetrates through the upper end of the housing 5 and is threadedly connected to the upper end of the housing 5.

[0038] Rotating the adjusting bolt 33 allows adjustment of the height of the air distribution plate 3 within the housing 5, thereby adjusting the corresponding position of the annular groove 41 and the battery. As the air distribution plate 3 moves upward within the housing 5, the length of the upper end of the battery inserted into the housing 5 increases, and the height of the corresponding position of the annular groove 41 and the battery decreases. Conversely, the length of the upper end of the battery inserted into the housing 5 decreases, and the height of the corresponding position of the annular groove 41 and the battery increases. This facilitates adjustment of the corresponding position of the annular groove 41 and the battery, and makes it easier to heat-melt the adhesive in the groove at the joint between the battery cover 1 and the battery slot 2.

[0039] 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.
