Abstract
Description
Technical Field
[0001] This utility model relates to the field of lead-acid battery cover installation technology, and in particular to a cover clamping device for lead-acid batteries. Background Technology
[0002] A lead-acid battery is a type of rechargeable battery whose electrodes are primarily made of lead and its oxides, and whose electrolyte is a sulfuric acid solution. In the discharged state, the positive electrode is mainly composed of lead dioxide, and the negative electrode is mainly composed of lead; in the charged state, both the positive and negative electrodes are mainly composed of lead sulfate.
[0003] In the production process of lead-acid batteries, the cover is a crucial component. During installation, the cover needs to be tightened to ensure a good seal between it and the battery casing and top cover, preventing electrolyte leakage. When tightening the cover, it is typically installed in the corresponding position on the top cover to seal the positive or negative terminal of the battery. During the tightening process, firstly, it is necessary to ensure a tight, gapless fit between the cover and the top cover. Secondly, a suitable amount of sealant or a sealing gasket is usually applied between the cover and the top cover. After tightening, these sealing materials fill the tiny gaps between the cover and the top cover, forming an effective sealing layer to prevent electrolyte leakage.
[0004] However, existing technologies have some problems: during the manual application of sealant and pressing of the sealing cap, the varying skill levels of construction workers and prolonged mechanical work can lead to a loss of concentration, resulting in uneven distribution of the sealant during application, or even some areas being completely uncovered, thus failing to form an effective sealing layer. Furthermore, uneven pressing of the sealing cap can also cause seal deformation, affecting the sealing effect. Therefore, we propose a cover pressing device for lead-acid batteries. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a cover pressing device for lead-acid batteries. By cooperating with a metering component and a roller, it ensures a consistent amount of adhesive is dispensed each time the adhesive is applied, and the roller spreads the sealant evenly. Multiple damping rods are set below the lower template to achieve uniform pressure distribution when the upper pressure plate presses down, and to help prevent excessive pressure.
[0006] The purpose of this utility model is achieved as follows: A cover pressing device for lead-acid batteries includes a base, a support frame fixedly connected to the base, a pressing cavity formed on the base, a guide rod fixedly connected inside the pressing cavity, a lower template slidably connected inside the pressing cavity, an adhesive application assembly slidably connected to the base, an clearance groove provided on the support frame, the adhesive application assembly corresponding to the clearance groove, a metering component provided on the adhesive application assembly for controlling the amount of adhesive dispensed, a hydraulic rod provided on the support frame, and an upper pressing mold provided on the hydraulic rod.
[0007] Optionally, the lower template has a placement groove and a sliding hole, which is inserted into a guide rod. The lower template is correspondingly arranged with the upper pressure plate. Multiple damping rods are fixedly connected in the pressing cavity, and the damping rods are in contact with the lower template.
[0008] Optionally, the adhesive application assembly includes a mounting plate, a locking block is provided at the lower end of the mounting plate, an arc-shaped groove is provided on the locking block, a sliding groove is provided on the base, the locking block is slidably connected to the sliding groove, and the arc-shaped groove is correspondingly provided with the guide rod.
[0009] Optionally, the mounting plate is provided with a lead screw, which is driven to rotate by a motor. There are two lead screws, which are symmetrically distributed. A sliding plate is threaded onto the lead screw, and a roller is rotatably connected to the lower end of the sliding plate. The roller is correspondingly arranged with the lower template.
[0010] Optionally, the metering component includes a glue storage tank, a slider slidably connected to the slide plate, a fastening screw on the slider, the fastening screw being threadedly connected to the slide plate, a metering cylinder on the slider, a connecting pipe on the metering cylinder, the connecting pipe being fixedly connected to the glue storage tank, and a glue dispensing pipe on the slider, the metering cylinder being connected to the glue dispensing pipe.
[0011] Optionally, a cylinder is provided on the metering cylinder, a piston is fixedly connected to the output end of the cylinder, the piston is slidably connected to the metering cylinder, and a one-way valve is provided in the connecting pipe.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. By incorporating a roller and metering assembly, during operation, the piston moves upward, allowing sealant to enter the metering cylinder through a one-way valve in the connecting pipe. When the piston moves downward, the one-way valve closes, preventing sealant backflow and ensuring a consistent dispensing volume each time, thus improving the accuracy and efficiency of sealant application. The sealant is squeezed onto the roller and cover plate through the dispensing tube, and then rolled evenly by the roller, achieving uniform application of the sealant. This ensures a good sealing effect while reducing material waste.
[0014] 2. By setting damping rods and guide rods, after aligning the upper cover with the cover plate, the hydraulic rod is activated. The output end of the hydraulic rod drives the upper die to press downwards. The upper die moves downwards along the guide rods to prevent pressure deviation and ensure the accuracy and stability of pressing. When pressure is continuously applied, the damping rod below the lower die plate can contract evenly under force. The damping rod can deform under the pressure applied by the upper die, thereby absorbing and dispersing this pressure, ensuring a more uniform pressure distribution on the cover plate and avoiding situations where the local pressure is too high or too low.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 6 The lead-acid battery cover clamping device shown includes a base 1, a support frame 11 fixedly connected to the base 1, a pressing cavity 12 formed on the base 1, a guide rod 13 fixedly connected inside the pressing cavity 12, a lower template 2 slidably connected inside the pressing cavity 12, an adhesive application assembly 3 slidably connected to the base 1, an avoidance groove 15 provided on the support frame 11, the adhesive application assembly 3 being correspondingly arranged with the avoidance groove 15, a metering component 4 provided on the adhesive application assembly 3 for controlling the amount of adhesive dispensed, a hydraulic rod 16 provided on the support frame 11, and an upper pressing mold 17 provided on the hydraulic rod 16.
[0025] Furthermore, the guide rod 13 guides the lower template 2 and the upper die 17, ensuring stable movement of the upper die 17 during the pressing process, preventing deviation, and improving pressing accuracy. The metering component 4 precisely controls the amount of adhesive dispensed, avoiding waste. The hydraulic rod 16 provides stable and powerful pressing force, and the upper die 17, in conjunction with the lower template 2, achieves high-quality product pressing.
[0026] Specifically, the lower template 2 has a placement groove 21 and a sliding hole 22. The sliding hole 22 is inserted into the guide rod 13. The lower template 2 is correspondingly set with the upper pressure plate. Multiple damping rods 23 are fixedly connected in the pressing cavity 12 and the damping rods 23 are in contact with the lower template 2.
[0027] Furthermore, the damping rods 23 are evenly distributed within the pressing chamber 12, providing more uniform support for the lower template 2 and ensuring stable support. The insertion design of the sliding hole 22 and the guide rod 13 ensures the stability of the lower template 2 during the pressing process and prevents deviation. Simultaneously, the lower template 2 is correspondingly positioned with the upper pressure plate, guaranteeing the accuracy of the pressing. The multiple damping rods 23 fixed within the pressing chamber 12 contact the lower template 2, providing not only additional support but also absorbing impact during the pressing process, protecting the mold, and further improving the pressing quality and mold lifespan.
[0028] Specifically, the adhesive application assembly 3 includes a mounting plate 31, a locking block 32 at the lower end of the mounting plate 31, an arc-shaped groove 33 on the locking block 32, a sliding groove 14 on the base 1, the locking block 32 and the sliding groove 14 are slidably connected, the arc-shaped groove 33 is correspondingly set with the guide rod 13, a lead screw 34 is set on the mounting plate 31, the lead screw 34 is driven to rotate by a motor, there are two lead screws 34, the two lead screws 34 are symmetrically distributed, a sliding plate 35 is threadedly connected to the lead screw 34, a roller 36 is rotatably connected to the lower end of the sliding plate 35, and the roller 36 is correspondingly set with the lower template 2.
[0029] Furthermore, the sliding connection between the locking block 32 and the slide groove 14 allows the adhesive application assembly 3 to move smoothly along the base 1. The corresponding arrangement of the arc-shaped groove 33 and the guide rod 13 ensures accuracy during the adhesive application process. Two symmetrically distributed lead screws 34 are driven to rotate by a motor, which in turn moves the slide plate 35 back and forth, thereby controlling the contact between the roller 36 and the lower template 2 to achieve uniform adhesive application. This not only improves the adhesive application efficiency but also ensures the uniformity and quality of the adhesive application.
[0030] Specifically, the metering component 4 includes a glue storage tank 41, a slider 42 slidably connected to the slide plate 35, a fastening screw 43 on the slider 42, the fastening screw 43 being threadedly connected to the slide plate 35, a metering cylinder 44 on the slider 42, a connecting pipe 47 on the metering cylinder 44, the connecting pipe 47 being fixedly connected to the glue storage tank 41, a glue dispensing pipe 49 on the slider 42, and the metering cylinder 44 communicating with the glue dispensing pipe 49; a cylinder 45 on the metering cylinder 44, a piston 46 fixedly connected to the output end of the cylinder 45, the piston 46 being slidably connected to the metering cylinder 44, and a one-way valve 48 inside the connecting pipe 47.
[0031] Furthermore, by configuring the roller 36 and the metering component 4, during operation, the piston 46 moves upward, and the sealant enters the metering cylinder 44 through the one-way valve 48 of the connecting pipe 47. When the piston 46 moves downward, the one-way valve 48 closes to prevent the sealant from flowing back, ensuring a consistent amount of sealant dispensed each time and improving the accuracy and efficiency of sealant application. The sealant is squeezed onto the roller 36 and the cover plate through the dispensing pipe 49, and then rolled evenly by the roller 36, achieving uniform application of the sealant, which not only ensures the sealing effect but also reduces material waste.
[0032] Working principle: During operation, the cover plate is placed in the placement groove 21 of the lower template 2. Then, the mounting plate 31 is pulled until the arc groove 33 on the locking block 32 engages with the guide rod 13, and the locking block 32 supports the lower end of the lower template 2. The piston 46 is then activated, moving upwards. The sealant enters the metering cylinder 44 through the one-way valve 48 of the connecting pipe 47. When the piston 46 moves downwards, the one-way valve 48 closes, and the sealant is squeezed onto the roller 36 and the cover plate through the dispensing pipe 49. It is then rolled evenly by the roller 36. Align the top cover with the cover plate, activate the hydraulic rod 16, and the output end of the hydraulic rod 16 drives the upper pressure mold 17 to press downward. The upper pressure mold 17 moves down along the guide rod 13 to prevent pressure deviation. When the pressure is continuously applied, at the same time, the damping rod 23 below the lower template 2 can contract evenly when under force. The damping rod 23 can deform under the pressure applied by the upper pressure mold 17, thereby absorbing and dispersing this part of the pressure, ensuring that the pressure distribution on the cover plate is more uniform, and avoiding the situation of excessive or insufficient local pressure.
[0033] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
