The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] like Figures 1 to 7As shown, the sensor welding device of the present invention includes a workbench 1, a driving seat 2, a clamp 3, a welding head 4, a protective mechanism 5, an air suction mechanism 6 and a shielding mechanism 7. The driving seat 2 is connected to the top of the workbench 1, the clamp 3 is connected to the top of the driving seat 2, the driving seat 2 can drive the clamp 3 to rotate, the clamp 3 can clamp the sensor housing, the welding head 4 is connected to the driving arm, the driving arm is connected to the workbench 1, the driving arm can move the welding head 4 to the welding position of the sensor housing (the driving arm is a prior art, not shown in the figure, and will not be described in detail here), the protective mechanism 5 is connected to the workbench 1, and can block the spark materials generated during the welding of the sensor housing to prevent the spark materials from splashing onto the surface of the sensor housing, thereby avoiding inconvenience in the subsequent processing of the sensor. The wind suction mechanism 6 is connected to the protection mechanism 5, and the wind suction mechanism 6 includes a fan 61. The fan 61 can generate wind force to collect the splashing spark materials to prevent the splashing spark materials from falling to the outside. The shielding mechanism 7 is connected to the protection mechanism 5, and is used to block the fan 61 to prevent the splashing spark materials from affecting the normal operation of the fan 61.

[0028] like Figures 1 to 5 As shown, the protective mechanism 5 includes a mounting frame 51, a channel 52, an air pump 53, a telescopic part 54, a protective shell 55 and a transmission member 56. The mounting frame 51 is connected to the workbench 1. The channel 52 and the air pump 53 are both connected to the inner top wall of the mounting frame 51. The connecting end of the air pump 53 is connected to the channel 52. The telescopic part 54 and the protective shell 55 are both provided with two, and the two telescopic parts 54 are respectively plugged into the two ends of the channel 52. When the air pump 53 is started to transport gas or extract gas into the channel 52, the two telescopic parts 54 can be controlled to move closer to or farther away from each other. The two protective shells 55 are respectively provided on the two telescopic parts 54, and the two telescopic parts 54 are close to each other. The two protective shells 55 can be driven to approach each other and cover the outside of the sensor shell, and a notch 57 for welding the sensor shell to the welding head 4 is formed between the two protective shells 55, so as to facilitate the subsequent welding of the sensor shell by the welding head 4. The transmission parts 56 are provided in two groups, and the two groups of transmission parts 56 are respectively connected between the two protective shells 55 and the two telescopic parts 54. The two groups of transmission parts 56 can drive the two protective shells 55 to flip in the opposite direction when the two telescopic parts 54 move away from each other, so that the two protective shells 55 are arranged in a V shape, so as to facilitate the removal of the welded sensor shell and the replacement of the unwelded sensor shell.

[0029] Continue to refer Figures 1 to 5As shown, the transmission member 56 includes a rotating shaft 561, a torsion spring 562, a gear 563 and a tooth plate 564. The rotating shaft 561 is connected to the protective shell 55, and the protective shell 55 is rotatably connected to the telescopic part 54 through the rotating shaft 561. The torsion spring 562 is connected between the protective shell 55 and the telescopic part 54 to drive the protective shell 55 to reset. The gear 563 is connected to the rotating shaft 561, and the tooth plate 564 is connected to the channel 52. When the telescopic part 54 shrinks into the channel 52, the gear 563 can mesh with the tooth plate 564 for transmission, so that the rotating shaft 561 drives the protective shell 55 to flip, and the two protective shells 55 are arranged in a V shape, so as to remove the welded sensor shell and replace the unwelded sensor shell.

[0030] Start the air pump 53 to deliver gas to the channel 52, so that the two telescopic parts 54 are close to each other, and drive the two protective shells 55 to cover the outside of the sensor housing, and a gap 57 is formed between the two protective shells 55. Start the drive seat 2 to drive the clamp 3 to rotate, and the clamp 3 drives the sensor housing to rotate. The welding head 4 welds the sensor housing from the gap 57. The sparks and materials splashed during welding are blocked by the two protective shells 55 to avoid the sparks and materials splashing onto the surface of the sensor housing, which causes inconvenience to the subsequent processing of the sensor.

[0031] The air pump 53 is started to extract the gas in the channel 52 to move the two telescopic parts 54 away from each other, thereby driving the two protective shells 55 away from each other. When the gear 1 563 passes the tooth plate 1 564, the gear 1 563 and the tooth plate 1 564 are meshed and transmitted, so that the rotating shaft 561 drives the protective shell 55 to flip, and the two protective shells 55 are arranged in a V shape, so that the welded sensor shell can be removed and the unwelded sensor shell can be replaced.

[0032] like Figure 1 , Figure 5 and Figure 6 As shown, the two protective shells 55 are shell one 551 and shell two 552 respectively, shell one 551 is provided with cavity one 5511, shell two 552 is provided with cavity two 5521, the wind suction mechanism 6 includes a fan 61, air duct one 62 and air duct two 63, the fan 61 is connected in cavity one 5511, air duct one 62 is connected to shell one 551, air duct two 63 is connected to shell two 552, and air duct one 62 and air duct two 63 are plugged into each other.

[0033] When welding the sensor housing, start the fan 61 to generate wind force to guide the spark material, so that the spark material enters the cavity 1 5511 and is blocked by the shielding mechanism 7 to facilitate the collection of the spark material. The wind force generated by the fan 61 can enter the cavity 2 5521 through the air duct 1 62 and the air duct 2 63, and blow toward the cavity 1 5511 to enhance the guiding effect on the spark material. After welding is completed, when the shell 1 551 and the shell 2 552 move away from each other, the air duct 1 62 and the air duct 2 63 can be driven to separate.

[0034] like Figure 1 , Figures 5 to 7 As shown, the shielding mechanism 7 includes a transmission shaft 1 71, a transmission shaft 2 72, a shielding mesh belt 73, a scraper 74, a gear 2 75, a one-way bearing 76 and a tooth plate 2 77. The transmission shaft 1 71 and the transmission shaft 2 72 are both rotatably connected in the cavity 1 5511. The transmission shaft 1 71 is located below the transmission shaft 2 72, and one end of the transmission shaft 1 71 extends out of the housing 1 551. The shielding mesh belt 73 is transmission-connected between the transmission shaft 1 71 and the transmission shaft 2 72. The shielding mesh belt 73 is a steel mesh belt. The shielding mesh belt 73 is located between the fan 61 and the welding head 4 and is used to block sparks from entering the cavity 1 5511. Material is used to avoid spark materials from splashing onto the fan 61 and affecting the normal operation of the fan 61. The scraper 74 is connected in the cavity 5511. The top of the scraper 74 is in contact with the bottom of the shielding mesh belt 73. The transmission shaft 1 71, the transmission shaft 2 72 and the shielding mesh belt 73 can transmit power, and the scraper 74 scrapes the spark materials attached to the shielding mesh belt 73 into the cavity 5511 to avoid affecting the subsequent use of the shielding mesh belt 73. The gear 2 75 is connected to the end of the transmission shaft 1 71 extending out of the housing 551 through a one-way bearing 76, and the tooth plate 2 77 is connected to the tooth plate 1 564.

[0035] When the shell 1 551 and the shell 2 552 move away from each other, the gear 2 75 meshes with the tooth plate 1 564 for transmission. At this time, the transmission shaft 1 71 can be driven to rotate through the one-way bearing 76, so that the transmission shaft 1 71, the transmission shaft 2 72 and the shielding mesh belt 73 are transmitted. When the shell 1 551 and the shell 2 552 approach each other, the gear 2 75 meshes with the tooth plate 1 564 for transmission. At this time, the transmission shaft 1 71 will not be driven to rotate through the one-way bearing 76.

[0036] Working principle: Start the air pump 53 to deliver gas to the channel 52, so that the two telescopic parts 54 are close to each other, and drive the two protective shells 55 to cover the outside of the sensor housing, and a gap 57 is formed between the two protective shells 55. At this time, the gear 2 75 is meshed with the tooth plate 1 564 for transmission. At this time, the one-way bearing 76 will not drive the transmission shaft 1 71 to rotate. Start the drive seat 2 to drive the clamp 3 to rotate, and the clamp 3 drives the sensor housing to rotate. The welding head 4 welds the sensor housing from the gap 57, and the sparks and materials splashed during welding are blocked by the two protective shells 55.

[0037] Start the fan 61 to generate wind force to guide the spark material, so that the spark material enters the cavity 1 5511 and is blocked by the shielding mesh belt 73. The wind force generated by the fan 61 can enter the cavity 2 5521 through the air duct 1 62 and the air duct 2 63 and blow towards the cavity 1 5511.

[0038] Start the air pump 53 to extract the gas in the channel 52, so that the two telescopic parts 54 move away from each other, thereby driving the two protective shells 55 to move away from each other, and the gear 2 75 is meshed with the tooth plate 1 564 for transmission. At this time, the one-way bearing 76 can drive the transmission shaft 1 71 to rotate, so that the transmission shaft 1 71, the transmission shaft 2 72 and the shielding mesh belt 73 are transmitted, and the scraper 74 scrapes off the spark material attached to the shielding mesh belt 73.

[0039] When the gear 1 563 passes through the tooth plate 1 564 , the gear 1 563 and the tooth plate 1 564 mesh and transmit, so that the rotating shaft 561 drives the protective shell 55 to turn over, and the two protective shells 55 are arranged in a V shape.
