Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing agent casting, in particular to a handheld lead-acid battery sealing agent casting device. Background Art
[0002] Domestic underwater power lead-acid batteries use a sealant between the tank and cover. The sealant is made of modified asphalt, heated to a liquid state and then manually poured between the tank and cover using a ladle. The sealant connects the tank and cover to form a sealed battery, preventing the escape of acid mist generated during charging and discharging. It also prevents sulfuric acid electrolyte from escaping between the tank and cover if the battery tilts, ensuring battery safety during use.
[0003] Due to the large size (650mm long, 370mm wide, 1200mm high) and heavy weight (≥600kg) of underwater power batteries, automatic casting of sealants is difficult to achieve during production. Currently, manual casting with a spoon is still used. Due to structural reasons, the casting speed of the sealant cannot be adjusted using an ordinary spoon. During the casting process, local excessive speed may cause defects such as cracks and bubbles to appear on the surface of the sealant after cooling. At the same time, when using an ordinary spoon, it needs to be tilted at a certain angle during casting to ensure that the sealant flows out from the side wall of the spoon. This operation increases the labor intensity of the operator. Ordinary spoons do not have dedicated measuring scales. The amount of battery sealant can only be controlled by the operator's experience, which will lead to inconsistent sealant dosage and inconsistent battery sealant height, affecting the appearance quality. Utility Model Content
[0004] In response to the shortcomings of the prior art, the present invention aims to provide a handheld sealant casting tool. By adjusting the spring pressure on the pressure rod device to control the stroke of the lifting rod, the speed of the sealant casting can be controlled. A through-hole is provided at the bottom of the pouring spoon to allow the sealant to flow out from the bottom of the spoon, eliminating the need to tilt the spoon during pouring, thereby reducing the operator's labor intensity. The required sealant volume is calculated based on the amount used for each battery, and graduated lines are provided on the inner wall of the pouring spoon, allowing the operator to easily control the amount of sealant used for each battery, ensuring consistent casting of the sealant for each battery.
[0005] The utility model is realized by adopting the following technical solutions:
[0006] The handheld lead-acid battery sealing agent casting device includes a pouring spoon, a pouring hole is provided at the bottom of the pouring spoon, a lifting rod is provided inside the pouring spoon, the diameter of the lifting rod is larger than the diameter of the casting hole, the lifting rod abuts against the casting hole, and a handle is connected to the pouring spoon.
[0007] The pouring spoon is provided with through holes and casting scale lines, and each row of scale lines represents the amount of sealing agent used for one battery.
[0008] The pouring spoon is composed of two parts, the upper part is a cylinder and the lower part is an inverted cone. The tip of the inverted cone is provided with a casting hole.
[0009] Scale lines are provided on the vertical wall of the pouring spoon.
[0010] The handle is provided with a spring positioning column B and a positioning block, and the positioning block is located on a side close to the pouring spoon.
[0011] The handle, the spring positioning column and the positioning block constitute the handle device.
[0012] The lifting rod is connected to the pressure rod handle through a pin shaft, and a spring positioning column A is provided on the pressure rod handle.
[0013] The spring, the spring positioning column, the pin shaft and the lifting rod form a pressure rod device, and the pressure rod and the lifting rod are connected by a pin.
[0014] The positioning block is provided with a rotating shaft, the pressure rod handle passes through the rotating shaft and is connected with the lifting rod, and the pressure rod handle can rotate around the rotating shaft.
[0015] A spring is provided between the spring positioning column B and the pin shaft.
[0016] The working principle of this utility model is:
[0017] Before adding material, the lifting rod abuts against the casting hole, sealing the bottom of the ladle with the lifting rod and the casting hole. Liquid material is then added to the ladle. The ladle is then moved above the object to be cast, and the pressure rod handle is pressed, causing the lifting rod to move upward. The liquid material flows out through the casting hole, and the liquid level in the ladle is observed by the scale line. The spring is now in a compressed state. After casting is complete, the pressure rod handle is released, and the pressure rod handle moves upward on the spring, causing the lifting rod to move downward and abut against the casting hole again. The pressure rod assembly comprises the spring, spring locating column A, pin, and lifting rod, which are connected by a pin.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] (1) Use a handheld casting tool to control the lifting rod stroke by adjusting the spring pressure on the pressure rod device, thereby controlling the casting speed of the sealing agent and reducing defects such as cracks and bubbles on the sealing agent surface caused by uneven casting speed;
[0020] (2) Use a handheld casting tool to allow the sealant to flow out from the bottom of the pouring spoon. There is no need to tilt the pouring spoon during pouring, which reduces the labor intensity of the operator;
[0021] (3) The use of handheld casting tooling allows the operator to easily control the amount of battery sealing agent used, so that the casting amount of each battery sealing agent is basically the same and the battery sealing agent is highly consistent. BRIEF DESCRIPTION OF THE DRAWINGS
