[0002] The painting and gluing process for vehicles is to improve their rust and water resistance. Currently, due to the irregular shape of the vehicle body welds and the high precision requirements for gluing, the painting and gluing production line is equipped with sealant robots for spraying. However, due to visual deviations of the sealant robots and deviations in the position of the vehicle body entering the conveyor belt, the sealant robots will experience deviations in their gluing process. To solve this problem, operators need to perform autonomous teaching to adjust the gluing path of the sealant robots.

However, the human eye cannot accurately confirm the position of the application gun, which leads to a low teaching success rate.

[0004] Therefore, it is necessary to provide a new laser teaching aid to solve the above-mentioned technical problems. Utility Model Content

[0009] In one embodiment, the power supply assembly further includes a compression spring, one end of which is connected to the conductive unit, and the other end of which abuts against the negative terminal of the battery.

[0010] In one embodiment, the laser is a miniature laser head, and the laser beam emitted by the laser coincides with the spraying center axis of the sealant robot's applicator gun.

[0011] In one embodiment, the laser teaching aid further includes a fastening bolt, and the mounting base has a locking hole through which the fastening bolt passes for mounting to the sealant robot.

[0015] In the above scheme, the laser teaching aid includes a mounting base, a housing, a laser, a power supply assembly, and a toggle switch. The mounting base is used to install on the sealant robot. The housing is mounted on the mounting base and has a mounting hole.

[0029] To achieve the above objectives, please refer to Figures 1 to 6This utility model proposes a laser teaching aid 100, including a mounting base 1, a housing 2, a laser 3, a power supply assembly 4, and a toggle switch 5. The mounting base 1 is used to install on a sealant robot 101. The housing 2 is installed on the mounting base 1 and has a mounting hole 21. The laser 3 is disposed inside the housing 2 and extends into the mounting hole 21. The power supply assembly 4 is disposed inside the housing 2 and is electrically connected to the positive terminal of the laser 3. The housing 2 has a mounting groove 22 and the toggle switch 5 is installed in the mounting groove 22. The toggle switch 5 includes a first terminal 51, a second terminal 52, and a third terminal 53. The first terminal 51 is electrically connected to the laser 3, and the second terminal 52 is electrically connected to the negative terminal of the power supply assembly 4. The second terminal 52 is used to connect the first terminal 51 or the third terminal 53. Specifically, the housing 2 is 3D printed and then mounted on the mounting base 1. A mounting hole 21 is made in the mounting base 1. The power supply assembly 4 and the laser 3 are both placed inside the housing 2, with the laser 3 extending out of the mounting hole 21, allowing the light emitted by the laser 3 to exit the housing 2. To power the laser 3, the positive terminal of the power supply assembly 4 is electrically connected to the laser 3. A mounting groove 22 is made in the housing 2, and a toggle switch 5 is mounted in the mounting groove 22. The toggle switch 5 includes a first terminal 51, a second terminal 52, and a third terminal 53. The first terminal 51 is electrically connected to the laser 3, and the second terminal 52 is electrically connected to the negative terminal of the power supply assembly 4. The second terminal 52 is used to connect either the first terminal 51 or the third terminal 53. By switching the connection state of the toggle switch 5, the laser 3 can be powered. Power supply component 4 supplies or de-energizes laser 3, thus completing the entire laser teaching aid 100. During teaching, mounting base 1 is installed on sealant robot 101, synchronizing the laser projection path with the robot's movement trajectory in real time. By switching the terminal connection state of toggle switch 5, power supply component 4 supplies power to laser 3. The toggle switch 5 enables rapid on / off switching of laser 3, ensuring operational continuity during teaching. When operators modify the path, the visible light spot projected by laser 3 forms a physical reference. When operators move sealant robot 101 along the adhesive application path, laser 3 directly provides visual reference for the adhesive application path, solving the problem that operators cannot accurately confirm the path of the coating gun with their eyes, thereby improving the success rate of teaching. Housing 2 simultaneously supports core components such as laser 3 and power supply component 4, forming a closed protective structure to prevent dust in the coating workshop from contaminating the optical components. Independent power supply component 4 is directly connected to laser 3 for power supply, preventing workshop voltage fluctuations from affecting laser stability.

[0030] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6In one embodiment, the housing 2 includes a top cover 23, and the power supply assembly 4 includes a battery 41, a conductive unit 42, a negative electrode spring 43, and a positive electrode conductive plate 44. The conductive unit 42 is mounted on the top cover 23. The positive electrode of the battery 41 abuts against the positive electrode conductive plate 44, the negative electrode of the battery 41 is connected to one end of the conductive unit 42, and the other end of the conductive unit 42 is connected to the negative electrode spring 43. The second terminal 52 is electrically connected to the negative electrode spring 43. The conductive unit 42 is mounted on the top cover 23, making the installation and replacement of the battery 41 simpler and faster. Since the positive electrode of the battery 41 directly abuts against the positive electrode conductive plate 44, and the negative electrode is connected to the negative electrode spring 43 through the conductive unit 42, the entire circuit connection can be automatically completed when installing or replacing the battery 41, without the need for additional manual wiring or soldering steps. By electrically connecting the second terminal 52 to the negative electrode spring 43, the power supply state of the power supply assembly 4 to the laser 3 can be conveniently controlled by the toggle switch 5. This design not only improves ease of use but also enhances the safety and reliability of the system, as operators can quickly and accurately cut off the power. This structural layout optimizes the utilization efficiency of the internal space of the housing 2, allowing the components to be arranged closely and orderly, which is conducive to reducing the overall size and facilitating maintenance and repair.

[0031] Please see Figures 3 to 6 In one embodiment, the housing 2 further includes an outer shell 24, which has a first mounting position 241, a second mounting position 242, and a third mounting position 243. Mounting holes 21 are provided on a top cover 23, which is mounted on the housing 2 to cover the first mounting position 241, the second mounting position 242, and the third mounting position 243. The laser 3 is mounted on the second mounting position 242, the negative electrode spring 43 is connected to the bottom of the groove in the third mounting position 243, and the positive electrode conductive sheet 44 is mounted on the bottom of the groove in the first mounting position 241. By setting different mounting grooves 22 to respectively house the laser 3, the negative electrode spring 43, and the positive electrode conductive sheet 44, a modular layout of the components is achieved. This design not only simplifies the manufacturing process but also improves assembly efficiency and facilitates later maintenance and component replacement. Each component is rationally allocated to a specific mounting groove 22, making the overall structure more compact and stable, preventing the components from shaking during teaching. The design of the top cover 23 covering these mounting slots 22 can provide additional physical protection for the internal components, preventing damage from impacts or vibrations during use.

[0032] Please see Figure 5 and Figure 6In one embodiment, the power supply assembly 4 further includes a compression spring 45, one end of which is connected to the conductive unit 42, and the other end of which abuts against the negative terminal of the battery 41. The compression spring 45 is designed to ensure tight contact between the negative terminal of the battery 41 and the conductive unit 42. The compression spring 45 compresses the battery 41, ensuring that the positive terminal of the battery 41 is always in contact with the positive conductive plate 44, preventing poor contact. By using the compression spring 45, batteries of different sizes and specifications can be accommodated, as long as their negative terminals can be effectively contacted by the compression spring 45. This increases the compatibility of the power supply assembly 4 with different types of batteries 41, improves the system's flexibility and adaptability, and good contact means lower resistance and lower heat generation, which helps reduce localized overheating problems caused by poor contact, thereby protecting the battery 41 and circuit components from damage and extending the overall lifespan of the device.

[0033] In one embodiment, the laser 3 is a miniature laser head, and the laser beam emitted by the laser 3 coincides with the spraying center axis of the glue application gun of the sealant robot 101. The precise alignment of the laser beam with the spraying center axis of the glue application gun ensures that the laser point can accurately indicate the glue application path, allowing the operator to further confirm and adjust the robot's walking path with greater precision, thereby improving the accuracy of the glue application operation.

[0034] Please see Figure 1 and Figure 2 In one embodiment, the laser teaching aid 100 further includes a fastening bolt 6, and the mounting base 1 has a locking hole 11. The fastening bolt 6 passes through the locking hole 11 for mounting on the sealant robot 101. First, the glue gun head on the sealant robot 101 is removed, and then the mounting base 1 is installed in the original position of the glue gun on the sealant robot 101 using the fastening bolt 6. This allows for quick removal and installation of the mounting base 1.

[0035] Please see Figure 1 and Figure 2 In one embodiment, there are multiple fastening bolts 6 and multiple locking holes 11. The number of locking holes 11 is equal to the number of fastening bolts 6, and they are arranged in a one-to-one correspondence. By setting this structure, the installation firmness of the mounting base 1 can be improved.

[0036] In one embodiment, the mounting base 1 is a magnetic mounting base, which is used to adhere to the sealant robot 101. First, the glue gun head on the sealant robot 101 is removed, and then the mounting base 1 is directly adhered to the original position of the glue gun head on the sealant robot 101. This can further improve the speed of removing and installing the mounting base 1.

[0037] In one embodiment, the laser teaching aid 100 further includes a removable transparent protective cover over the laser 3. The transparent protective cover covers the portion of the laser that extends out of the mounting hole 21, thus providing an additional physical protection layer for the laser 3, preventing damage during operation due to impacts, drops, or contact with foreign objects. The transparent protective cover effectively blocks dust, particulate matter, and other contaminants from entering the laser 3, preventing these substances from depositing on the optical components and affecting the performance of the laser 3. Simultaneously, due to its transparency, it does not obstruct the normal emission of the laser beam.

[0038] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
