Description

Technical Field

[0001] The present invention relates to the technical field of storage batteries, and in particular to a surface heating device for a storage battery. Background Art

[0002] The outer shell of battery products is made of plastic products such as ABS. It is easy for the outer shell surface to be scratched by friction on the production line, resulting in a poor appearance of the battery. Therefore, an electrostatic film is affixed to the surface of the plastic shell for protection. Maintenance-free batteries need to be acidified and charged before leaving the factory. During this process, the battery generates a lot of heat and needs to be placed in a water bath to cool down. The electrostatic film affixed to the surface of the plastic shell cannot be completely flat and fit well. There are bubbles in some places. The places with bubbles have a heat-insulating effect, resulting in a high temperature on the surface of the battery shell in the places with bubbles, causing the color of the shell surface to change. After the battery is off the production line, patterns appear on the battery surface, affecting the appearance of the battery. Currently, when the product appearance is inspected in the factory, workers are usually required to use a hot air gun to heat the defective shell to remove the pattern. When baking is required, manual observation and identification are required. Otherwise, the location of the pattern is easy to miss, resulting in low work efficiency.

[0003] Therefore, a battery surface heating device is needed to facilitate re-baking the surface of the battery shell with patterns so that the patterns disappear. Summary of the Invention

[0004] The main purpose of the present invention is to provide a battery surface heating device, which is equipped with a hot air device on a lifting device, and then uses the hot air device to heat and bake the surface of the battery shell with problems to remove the patterns on the battery surface, so that the product appearance meets the use requirements.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A battery surface heating device comprising:

[0007] base plate;

[0008] A lifting device, the lifting device is arranged on the base plate;

[0009] A hot air device, the hot air device is fixed on the lifting device, and the air outlet of the hot air device is arranged toward the battery to be heated;

[0010] A limiting device is fixed to the base plate and is arranged in front of the lifting device to limit the position of the battery to be heated.

[0011] Furthermore, the lifting device includes a top plate, a guide rod A, a screw rod, a slider, and a drive motor. The two ends of the guide rod A are fixedly connected to the bottom plate and the top plate respectively. The bottom of the screw rod is rotatably connected to the bottom plate, the top is rotatably connected to the top plate and is transmission-connected to the drive end of the drive motor. The slider is movably connected to the screw rod, and both ends are slidably connected to the guide rod A. The hot air device is fixedly connected to the slider.

[0012] Furthermore, the hot air device includes a fan, a heater, and an air outlet which are sequentially connected from top to bottom, and the air outlet is fixedly connected to the slider.

[0013] Furthermore, the air outlet is provided with a accommodating cavity, the air inlet of the accommodating cavity is connected to the heater, and the air outlet is arranged in a flat shape, and the length is greater than the length of the battery to be heated.

[0014] Furthermore, the limiting device includes two L-shaped blocks arranged opposite to each other, and the positions of the L-shaped blocks are adjustable and fixedly connected to the base plate.

[0015] Furthermore, a stepped strip groove is provided on the bottom plate, and the L-shaped stopper is fixedly connected to the bottom plate by bolts passing through the strip groove, and a relatively arranged photoelectric switch is installed on the L-shaped stopper.

[0016] Furthermore, a pushing device is provided on the bottom plate, and the cylinder is provided on the rear side of the lifting device for pushing the battery to be heated to a specified position, and a rubber pad is provided on the end of the guide rod of the cylinder.

[0017] Furthermore, a guide device is also provided on the base plate, and the guide device includes a fixed plate and a guide bar. The fixed plate is fixedly connected to the base plate, and the guide bar is rotatably connected to a screw rod close to the side of the fixed plate. The screw rod is threadedly connected to the fixed plate, and the guide bar is provided with guide rods B on both sides of the screw rod, and the guide rods B are connected to the guide holes provided in the fixed plate.

[0018] Furthermore, the end of the guide bar away from the lifting device is bent toward the outside.

[0019] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0020] First, this patent heats the battery shell from top to bottom by fixing a hot air device on a lifting device. By setting a lifting device, the heating time of the shell by the hot air device is controlled, which can effectively avoid the problem of excessive local heating time. At the same time, by setting a limit device, it can ensure that the distance between the air outlet of the hot air device and the battery shell is the same each time, ensuring the consistency of the heating effect and facilitating adjustment as needed.

[0021] Second, by setting the lifting device as a lifting slider driven by a driving motor, a stepping motor can be used to control the transmission speed, thereby controlling the movement speed of the slider installed with the hot air device. By setting the guide rod A, the slider movement is made more stable.

[0022] Third, in order to ensure the stability of the hot air device, the hot air device is arranged from top to bottom into three parts: a fan, a heater, and an air outlet. The fan sucks air to blow the air heated by the resistance wire in the heater into the air outlet and is sprayed toward the battery shell for heating, thereby removing the pattern on the surface of the shell. This makes it easy to replace the heating wire in the heater and the upper fan, and the structure is simple.

[0023] Fourth, by providing a receiving cavity in the air outlet, the hot air can be conveniently mixed and then blown out from the flat air outlet, so that the shell is heated more evenly.

[0024] Fifth, by setting the limiting device as an L-shaped block, the position where the battery is manually lowered can be unified.

[0025] Sixth, by setting a photoelectric switch, it is possible to detect whether the battery housing is placed in the designated position before the lifting device works, thereby avoiding ineffective operation of the system.

[0026] Seventh, by setting a cylinder to push the battery, the battery can be pushed out of the L-shaped block range, so that the distance between the air outlet of the hot air device and the shell is guaranteed to be consistent, and at the same time, the L-shaped block will not block the position of the shell.

[0027] Eighth, by providing the strip groove, the installation position of the L-shaped stopper can be easily adjusted, which is suitable for battery surfaces of different widths.

[0028] Ninth, by providing a guide device and adjusting the distance between the guide bars, the guide position can be adapted to different types of batteries. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1-3 As shown, a battery surface heating device includes:

[0034] Bottom plate 10;

[0035] A lifting device 20, the lifting device 20 is provided on the base plate 10;

[0036] A hot air device 30 is fixed to the lifting device 20, and an air outlet of the hot air device 30 is arranged toward the battery to be heated;

[0037] The limiting device 40 is fixed on the base plate 10 and is arranged in front of the lifting device 20 to limit the position of the battery to be heated.

[0038] Specifically, the lifting device 20 controls the up and down movement of the hot air device 30, thereby controlling the time for the hot air device 30 to heat the shell, ensuring that the shell will not be deformed due to excessive heating time. At the same time, a limiting device is set to limit the placement position of the battery, so as to ensure the consistency of the position of the battery when it is placed.

[0039] Furthermore, the lifting device 20 includes a top plate 201, a guide rod A202, a screw rod 203, a slider 204, and a drive motor 205. The two ends of the guide rod A202 are respectively fixedly connected to the bottom plate 10 and the top plate 201. The bottom of the screw rod 203 is rotatably connected to the bottom plate 10 and the top is rotatably connected to the top plate 201 and is transmission-connected to the drive end of the drive motor 205. The slider 204 is movably connected to the screw rod 203 and is slidingly connected to the guide rod A202 at both ends. The hot air device 30 is fixedly connected to the slider 204.

[0040] Specifically, in order to further ensure the stability of the movement of the lifting device 20, the driving motor 205 can be a stepping motor.

[0041] Furthermore, in order to facilitate the replacement of the heating device in the hot air device 30, the hot air device 30 includes a fan 301, a heater 302, and an air outlet 303 connected in sequence from top to bottom, and the air outlet 303 is fixedly connected to the slider 204. The hot air device 30 has a simple structure and is easy to disassemble and replace vulnerable devices.

[0042] Furthermore, in order to ensure the stability of the air outlet 303, the air outlet 303 is provided with a accommodating chamber 3031, the air inlet of the accommodating chamber 3031 is connected to the heater 302, and the air outlet is flat and has a length greater than the length of the battery to be heated.

[0043] Furthermore, the limiting device 40 includes two L-shaped stoppers 401 arranged opposite to each other, and the positions of the L-shaped stoppers 401 are adjustable and fixedly connected to the bottom plate 10 .

[0044] Furthermore, a stepped strip groove 101 is provided on the base plate 10, and the L-shaped stopper 401 is fixedly connected to the base plate 10 from the bottom by bolts passing through the strip groove 101, and a relatively arranged photoelectric switch 4011 is installed on the L-shaped stopper 401.

[0045] Furthermore, a cylinder 102 is provided on the base plate 10 . The cylinder 102 is provided at the rear side of the lifting device 20 and is used to push the battery to be heated to a specified position. A rubber pad is provided at the end of the guide rod of the cylinder 102 .

[0046] Furthermore, a guide device 103 is also provided on the base plate 10, and the guide device 103 includes a fixed plate 1031 and a guide bar 1032. The fixed plate 1031 is fixedly connected to the base plate 10, and the guide bar 1032 is rotatably connected to a screw 1033 close to the side of the fixed plate 1031. The screw 1033 is threadedly connected to the fixed plate 1031. The guide bar 1032 is located on both sides of the screw 1033 and has guide rods B1034. The guide rods B1034 are connected to the guide holes provided in the fixed plate 1031.

[0047] Furthermore, the end of the guide bar 1032 away from the lifting device 20 is bent toward the outside.

[0048] The specific working process is that the worker first places the battery to be heated on the base plate 10, adjusts the fixed position of the guide bar 1032 and the L-shaped block 401 as needed, and adjusts the extension length of the guide rod of the cylinder 102 to meet the use requirements, and pushes the battery to be heated to the position of the L-shaped block 401. After the photoelectric switch 4011 detects the presence of the battery, the guide rod of the cylinder 102 pushes the battery away from the L-shaped block 401. The lifting device 20 drives the hot air device 30 to descend to heat the battery shell, where the air outlet is 3-5mm away from the battery shell for heating. By setting the time to complete a lifting process of the lifting device 20 once, the heating effect of the battery is controlled to meet the use requirements (controlling the movement time of the drive motor, controlling the extension and contraction of the cylinder and the photoelectric switch 4011 are all controlled by a controller. Since how to control the controller is a conventional technical means for those skilled in the art, this patent will not describe it in detail).
