[0001] The utility model relates to the technical field of mechanical manufacturing and processing, in particular to a protective lens for a laser welding machine. Background Art

[0002] Laser welder protection lens is a key component specially designed for laser welding equipment. Its main function is to protect the optical components during the laser welding process and ensure the stability and clarity of the laser beam. Laser welder protection lens is usually made of high-transmittance and high-wear-resistant materials, such as optical glass, crystal, sapphire or special alloys. These materials have excellent light transmittance and wear resistance, which can ensure that the laser beam is not lost during transmission and maintain its original energy and focusing effect.

[0003] During the laser welding process, a large amount of high-temperature spatter will be generated, such as metal droplets, smoke, etc. If these spatters directly contact the laser focusing lens or other optical components, they will cause serious damage, affecting the focusing effect of the laser beam and the welding quality. Therefore, the laser welder protective lens can effectively block these spatters and protect the optical components from damage. The stability of the laser beam is very important to the welding quality. The laser welder protective lens can ensure that the laser beam is not disturbed by the outside world during the transmission process, maintain its original energy and focusing effect, thereby ensuring the stability and reliability of the welding process.

[0004] However, when replacing the protective lens of the laser welder in the prior art, the protective lens is removed and then the opening of the installation groove is sealed with tape to prevent dust from entering the installation groove and affecting the normal use of the protective lens. It is complicated to seal the opening with tape every time the protective lens is replaced, which is inconvenient to use. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a laser welder protective lens to solve the technical problem in the prior art that when replacing the laser welder protective lens, the protective lens must be removed and then the opening of the mounting groove must be sealed with tape to prevent dust from entering the mounting groove and affecting the normal use of the protective lens. The opening must be sealed with tape every time the protective lens is replaced, which is complicated and inconvenient to use.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laser welding machine protective lens, comprising a welding machine main body, a movable block is arranged in the welding machine main body, a supporting block is fixedly connected to the bottom of the movable block, a slot is provided in the welding machine main body for use with the movable block and the supporting block, a fixed block is fixedly connected in the welding machine main body, a telescopic rod is fixedly connected in the fixed block, a blocking block is fixedly connected to the output end of the telescopic rod, the blocking block is located above the slot, and a card slot is provided on the supporting block.

[0007] By adopting the above technical solution, when in use, the protective lens is fixed on the supporting block through the card slot, and the protective lens can be inserted into the welding machine body through the mutual cooperation between the movable block and the slot, so as to be used in conjunction with the laser welder. When the protective lens in the laser welder needs to be replaced, the movable block and the supporting block are first taken out from the slot, and then the blocking block is driven to move by the telescopic rod until the blocking block blocks the slot opening, so as to achieve a dust-proof effect. When the protective lens is pulled out of the mounting slot, the blocking block can quickly block the slot to form a barrier, which can not only prevent dust and impurities from further invading the interior of the equipment, but also protect the slot from erosion by the external environment to a certain extent, thereby extending its service life.

[0008] The utility model is further configured such that bolts are threadedly connected to the movable block in a symmetrical structure, and thread grooves for matching with the bolts are provided on the welding machine body.

At the same time, the rubber material has good elasticity and shock absorption performance. When subjected to external force impact, the protrusion can effectively absorb and disperse the impact force, play a buffering role, thereby protecting the parts in contact with it from damage.

[0014] The utility model is further configured such that a movable groove for cooperating with the blocking block is provided in the welding machine body, a sealing strip is provided on the outside of the blocking block, the blocking block is consistent in size with the slot opening, and the sealing strip is made of rubber material.

[0015] By adopting the above technical solution, the movable groove provides a clear positioning and movable space for the block, thereby ensuring that the block can be accurately inserted into the predetermined position, and the rubber sealing strip has good elasticity and sealing performance, and can fit tightly between the movable groove and the block. This structure effectively prevents external dust, moisture and other impurities from entering the main body of the welding machine, protecting the electrical components and mechanical parts inside the welding machine. The consistency of the size of the block and the slot opening ensures that the block can be tightly inserted into the slot, thereby achieving better dustproof effect.

[0016] The present invention is further configured such that a button for use with the telescopic rod is fixedly connected to the outside of the welding machine body, and the button is electrically connected to the telescopic rod.

[0017] By adopting the above technical solution, the provided button enables the staff to drive the telescopic rod so that the block blocks the slot opening when replacing the protective lens of the laser welder.

[0018] The utility model is further configured such that the welding machine body is made of stainless steel, a welding head is provided on one side of the welding machine body, and a groove is provided at the bottom of the movable block for use with the blocking block.

[0019] By adopting the above technical solution, when the welding machine body is made of stainless steel, the welding machine body can withstand greater mechanical stress and thermal stress, ensuring that the welding machine body can still maintain a stable working state under long-term, high-intensity working conditions. The mutual cooperation between the welding machine body and the welding head can enable the entire laser welder to be used normally, and through the groove at the bottom of the movable block, the blocking block can be stably set in the welding machine body and used in conjunction with the slot. The groove has a certain accommodating and limiting effect on the blocking block.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. The utility model fixes the protective lens on the supporting block through the card slot. Through the mutual cooperation between the movable block and the slot, the protective lens can be inserted into the welding machine body, so as to cooperate with the laser welding machine for use. When the protective lens in the laser welding machine needs to be replaced, the movable block and the supporting block are first taken out from the slot, and then the blocking block is driven to move by the telescopic rod until the blocking block blocks the slot opening, so as to achieve the dust-proof effect. When the protective lens is pulled out of the installation slot, the blocking block can quickly block the slot to form a barrier, which can not only prevent dust and impurities from further invading the interior of the equipment, but also protect the slot from erosion by the external environment to a certain extent, thereby extending its service life.
