Description

Technical Field

[0001] The invention belongs to the technical field of lead-acid batteries, and in particular relates to an efficient and durable automatic installation device for a double-rotating disk lead-acid battery safety valve. Background Art

[0002] Lead-acid batteries have a positive electrode made of lead dioxide, a negative electrode made of sponge-like lead, and an electrolyte made of aqueous sulfuric acid. The separator (diaphragm) is made of microporous rubber separators, microporous plastic separators, or other materials depending on the type of lead-acid battery. The battery casing is made of hard rubber, engineering plastics, fiberglass, and other materials. During operation, the battery generates gas, which increases the internal pressure of the battery and poses a safety hazard. Therefore, a safety valve needs to be installed on the battery to form a valve-regulated battery.

[0003] In the prior art, the Chinese utility model with application number: CN202021594916.1 discloses a lead-acid battery safety valve, comprising: a valve seat, a cylindrical column is provided in the middle of the valve seat; a first air filter is fixed to the bottom of the cylindrical column by hot pressing; a rubber cap is provided on top of the cylindrical column; a positioning member is provided above the rubber cap; a second air filter is provided above the positioning member; and a valve cover is provided on the top of the valve seat. The utility model is provided with two air filters. When the internal pressure of the battery is too high and exhaust is required, the gas pushes open the four sides of the rubber cap. The second air filter can ensure that the gas is discharged in time, and the first air filter can prevent the acidic electrolyte from flowing out. The coordinated use of the first air filter and the second air filter can prevent the rubber cap from being corroded by acid mist, thereby improving the service life of the safety valve.

[0004] However, during the installation process of the safety valve, the safety valve needs to be transferred to the designated position. These actions are mostly completed manually, which requires a lot of labor, resulting in slow installation efficiency, uneven quality, and high labor costs.

[0005] To this end, we propose an efficient and durable double-turntable lead-acid battery safety valve automatic installation equipment to solve the problems existing in the existing technology. It is convenient and fast to transport the lead-acid battery and the installation valve so that the lead-acid battery and the installation valve arrive at the designated installation position synchronously. The installation valve is further pressed onto the lead-acid battery through a pre-pressing device, which reduces manual operation, improves the installation efficiency of the lead-acid battery, and ensures the installation quality of the safety valve on the lead-acid battery.

[0033] The present invention provides Figure 1-6 The invention discloses an efficient and durable double-rotating disk lead-acid battery safety valve automatic installation device, comprising:

[0039] The arrangement mechanism 8 includes a right-angle plate 81, and a third cylinder 82 and a first guide rail 87 are provided on the upper surface of the right-angle plate 81.

Two groups of first guide rods 66 passing through the movable seat 64 are fixedly connected to the upper surface of the base plate 67. The safety valve can be grabbed through the suction cup 72, which improves the convenience of moving the safety valve.

[0043] The pressing mechanism 10 includes a pressing cylinder 101, and a claw clamp 102 is provided at the telescopic end of the pressing cylinder 101. A second photoelectric sensor 103 is provided on one side of the claw clamp 102. The second photoelectric sensor 103 is used to detect the safety valve on the carrier 11, so that the second adjustment mechanism 9 can adjust the position of the pressing mechanism 10, making it convenient for the pressing mechanism 10 to press the safety valve onto the lead-acid battery.

[0044] The second positioning mechanism 9 includes a fourth cylinder 91 and a second guide rail 92 arranged on one side of the mounting plate 5. The telescopic end of the fourth cylinder 91 is provided with a sliding seat 93 sliding on the second guide rail 92. A horizontal guide frame 94 is provided on one side of the sliding seat 93. A fixed plate 95 for installing the press-fitting cylinder 101 is slidably provided on the horizontal guide frame 94.

According to the different positions of the safety valve on the carrier, the position of the press-fitting mechanism 10 can be fine-tuned to ensure the accuracy of the installation position of the safety valve.

[0045] The battery positioning mechanism 13 includes a vertical plate 131 installed on the conveying device 12, and a positioning cylinder 132 is provided on one side of the vertical plate 131. The telescopic end of the positioning cylinder 132 is provided with a positioning clamping plate 133 for fixing the lead-acid battery. One side of the positioning clamping plate 133 is connected to two groups of third guide rods 134 that pass through the vertical plate 131. The lead-acid battery can be quickly positioned through the battery positioning mechanism 13, thereby ensuring the stability of the lead-acid battery during the installation of the safety valve and improving the quality of the safety valve installation. Through the automated and modular design, efficient and high-precision installation of the lead-acid battery safety valve is achieved.

[0046] Step 1: During use, the two sets of vibrating plates 3 are driven to operate synchronously by the deceleration drive mechanism 2, and the two sets of vibrating plates 3 convey the safety valves to the arrangement mechanism 8 via the linear guide rail 4. The arrangement mechanism 8 arranges and arranges the safety valves in multiple sets of valve slots 84 through the third cylinder 82 and the pre-stored plate 83, and uses the first photoelectric sensor 86 to detect whether the valve slots 84 are loaded with safety valves to ensure accurate arrangement of the safety valves.

[0047] Step 2: The first positioning mechanism 6 drives the movable base 64 via the screw 62 and the first motor 63, driving the grabbing mechanism 7 to move above the safety valve. The third cylinder 82 moves the pre-stored plate 83 to the bottom of the grabbing mechanism 7. The grabbing mechanism 7 grabs the safety valve via the suction cup 72. The first positioning mechanism 6 is reset to position the grabbing mechanism 7 above the carrier 11. The second cylinder 71 moves the suction cup 72 onto the carrier 11, and the multiple safety valves are placed in the placement slots of the carrier 11.

[0048] Step 3: The second positioning mechanism 9 adjusts the position of the press-fitting mechanism 10 via the fourth cylinder 91 and the fifth cylinder 96 to ensure that the press-fitting cylinder 101 can drive the claw clamp 102 to clamp the safety valve. The conveying device 12 positions the lead-acid battery via the battery positioning mechanism 13 and aligns the installation position of the safety valve of the lead-acid battery under the detection of the third photoelectric sensor 14 to ensure that the press-fitting position of the safety valve is accurate.

[0049] After a set of safety valves are press-fitted, repeat the above step 3 to complete the installation of all the safety valves on the carrier 11, then repeat the steps 1 to 3 to complete the cyclic installation of the safety valves on the battery, and use the inspection camera 16 to inspect the installation quality of the safety valves after press-fitting.
