Description

Technical Field

[0001] The utility model relates to the technical field of battery cover plate processing equipment, in particular to a battery cover plate laser engraving tool. Background Art

[0002] The working principle of laser coding equipment is to focus the laser at extremely high energy density on the surface of the object to be marked, vaporize the surface material through burning and etching, and accurately burn out the desired pattern or text by controlling the effective displacement of the laser beam.

[0003] During the processing of battery cover, laser coding equipment is needed for coding. The currently used battery cover laser coding tooling, such as Figure 1 As shown, the main structure includes a base plate 01, a vertical plate 02, a support plate 03, a positioning column 04, and a dust suction nozzle 05. Among them, the base plate 01 is used to fix it as a whole on the table of the coding machine through screws and reserved screw holes. The support plate 03 is fixed to the vertical plate 02 by screws through the support of the vertical plate 02, so that there is a certain height difference between the support plate 03 and the base plate 01, which is convenient for the installation of the dust removal mechanism. When in use, the cover plate 06 is manually placed on the support plate 03, and the four positioning columns 04 on the upper, lower, left and right sides are used to fix the accurate position of the coding to prevent the coding position from shifting. The coding switch is turned on. After the coding is completed, the cover plate 06 is manually removed to complete the laser coding process. During the process, the dust suction nozzle 05 will continue to suction dust.

[0004] However, the vacuum nozzle of the existing battery cover laser engraving tooling is in a flat oval shape, the vacuum range of the vacuum nozzle is small, and the vacuum nozzle is positioned on the side of the battery cover to absorb dust. The wind resistance is large during vacuuming, and the dust removal effect is poor. Moreover, since the cover is directly placed in, the position of the dust removal device is limited. If the position is too close to the cover, it will affect the placement of the cover, and there is a possibility of the battery cover being bumped. Therefore, the dust removal position is too far from the welding position, and there is a height difference with the surface of the battery cover, and the dust removal effect is poor. In addition, the cover is located directly below the laser, and manual operation is required to pick up the battery cover, which poses a risk of accidental injury due to machine failure. Utility Model Content

[0005] In view of the current technology, the dust suction nozzle is positioned on the side of the battery cover to suck dust. The wind resistance is large during dust suction and the dust removal position is too far from the welding position. There is a height difference with the surface of the battery cover, and the dust removal effect is poor. In addition, the cover is positioned directly below the laser, and manual operation is required to pick up the battery cover. There is a technical problem that there is a risk of accidental injury due to machine failure. The purpose of this utility model is to provide a battery cover laser engraving tool.

[0006] To achieve the above purpose, the technical solutions provided by the present invention are as follows:

[0007] A battery cover laser coding tool includes a transition plate installed on the upper end of a coding machine table, a cover plate support plate installed on the upper end of the transition plate and capable of horizontal movement for placing the battery cover, and a dust removal cover vertically arranged directly above the battery cover and fixedly connected to the dust removal pipe. The dust removal cover is a cylindrical structure with upper and lower openings.

[0008] Wherein, a transparent protective lens is provided at the upper opening of the dust removal cover.

[0009] Wherein, an annular groove is provided on the inner side of the opening at the upper end of the dust removal cover, and the transparent protective lens can be detachably installed in the annular groove.

[0010] Wherein, the dust removal cover is a cylindrical structure.

[0011] Among them, the transition plate and the cover plate support plate are connected through a moving mechanism, and the moving mechanism includes a cylinder installed on the upper end surface of the transition plate and two sliding rail slider mechanisms connected between the transition plate and the cover plate support plate. The moving part of the cylinder is connected to the cover plate support plate and can drive the cover plate support plate to move.

[0012] Wherein, the transition plate and the cover plate support plate are provided with a magnetic attraction mechanism for fixing the positions of the two.

[0013] Among them, the magnetic attraction mechanism includes two magnet seats installed on both sides of the upper end surface of the transition plate, each of the magnet seats is installed with a first magnet block, and a second magnet block used in conjunction with the first magnet block is respectively arranged on the cover plate support plate at the corresponding position.

[0014] Wherein, a limit block for limiting the movement of the cover plate support plate is provided on the position of the transition plate on the opposite side of the magnet seat.

[0015] Wherein, a plurality of cover plate positioning columns with adjustable positions are provided on the cover plate support plate, and the battery cover plate is limited and fixed by the structure surrounded by the cover plate positioning columns.

[0016] Wherein, both sides of the lower end of the transition plate are respectively connected to a longitudinal vertical plate, and the outer ends of the longitudinal vertical plates are respectively connected to a support block, and the upper ends of the support blocks are in contact with the lower end of the transition plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The technical solution provided by this utility model adds a dust removal cover directly above the battery cover. This can cover the area where the dust is generated as much as possible without affecting the laser. Compared with the side-mounted flat-mouth dust suction port, it increases the dust removal area and surrounds or is close to the area where the dust is generated as much as possible to limit the spread of the dust, confining it to a smaller local space. It can also reduce the inhalation of external polluted air, while ensuring uniform negative pressure inside the cover, effectively controlling the dust-laden airflow, preventing dust from escaping from the cover, and optimizing the dust removal effect.

[0019] In addition, the dust collection effect is better when changing from side dust collection to vertical dust collection, mainly because the vertical dust collection method has the following advantages: Airflow direction: The airflow direction of vertical dust collection is upward. The air flows in from the opening at the lower end of the dust collector hood, passes through the area inside the dust collector hood, and is sucked away through the dust collection pipe, which is more effective in removing metal powder. In contrast, the airflow direction of side dust collection is horizontal, that is, the air flows in from the side, and the powder has to pass through the cover area. The dust collection trajectory is longer and the resistance is greater. If the dust is not removed in place, the powder falls on the cover and may be introduced into the battery, causing risks such as battery short circuit. Noise and energy consumption: The noise and energy consumption of the vertical dust collection method are relatively low because its airflow speed is slower. In contrast, the side dust collection method requires a higher airflow speed to maintain air flow, resulting in relatively high noise and energy consumption.

[0020] 2. In addition, the technical solution provided by this utility model adds a transparent protective lens to the upper end of the dust hood, which blocks the upper part of the dust hood and reduces the amount of air lost from the upper part of the dust hood during dust collection, thereby improving the dust collection effect. In addition, because the transparent protective lens is transparent, the laser can engrave the code through the protective lens without affecting the coding effect. The transparent protective lens isolates the dust collection environment from the external workshop environment, reducing air pollution in the workshop environment and optimizing the existing dust collection wind speed, which has been increased from 2.3m / s to 30m / s.

[0021] 3. In addition, the technical solution provided by the present invention adds a moving mechanism, which includes a cylinder and a slide rail slider mechanism. The cylinder is used as a power source, and the movement of the moving part of the cylinder generates thrust or pulling force, which drives the cover plate support plate and battery cover plate and other components on the slide rail slider mechanism to move linearly. Due to the coordinated use of the cylinder and the slide rail slider mechanism, high-precision position control can be achieved, and the battery cover plate can be driven to the exact position of the engraved code, which overcomes the situation where the dust cover is set directly above the battery cover plate to affect the placement of the battery cover plate, and enables the dust collection device to be adjusted to the position closest to the dust source as much as possible, thereby optimizing the existing dust removal effect. In addition, manual operation is changed to automatic operation, which simplifies the operating steps of employees and avoids employees operating directly under the laser, which may cause the risk of accidental injury due to machine failure.

[0022] 4. In addition, the technical solution provided by this utility model adds a magnet fixing structure to the existing laser coding machine tooling. To prevent the cover plate support from being pushed into place or shaking, which may cause inconsistent coding positions and garbled codes, magnets are added to the magnet base and cover plate support. When the magnet base and cover plate support reach a preset distance, they automatically adsorb together, ensuring the accuracy of coding during operation. The overall structure of the device is simple and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
