[0031] Example 1

[0032] Reference Figure 1 and Figure 2 , which is the first embodiment of the utility model, and this embodiment provides a fixing mechanism, which includes a limiting assembly 100. The limiting assembly 100 can be used to fix the shell of the tire pressure sensor that needs to be welded, and prevent the shell from being displaced during subsequent welding and fixing.

[0033] Specifically, the limiting assembly 100 includes a platform 101, a dividing plate 102 disposed on the end surface of the platform 101, a fixing table 103 disposed on the end surface of the dividing plate 102, a cylinder 104 disposed on the outer wall of the fixing table 103, and a motor 105 disposed on the end of the dividing plate 102.

[0034] Among them, the bottom of the platform 101 is provided with universal wheels, which can drive the platform to move, and a dividing plate 102 is arranged on the surface of the platform 101 directly above the platform 101. The dividing plate 102 can be driven to rotate on the surface of the platform 101 by the motor 105 below. The rotation of the dividing plate 102 drives the fixed table 103 around the upper surface of the dividing plate 102 to rotate. A product is fixed on the top of each fixed table 103. First, the housing of the tire pressure sensor is placed in the fixture 103c above the mounting plate 103b, and the housing is first placed and simply fixed. Then, the placement plate 104a above the fixed table 103 is driven to move downward by the cylinder 104 on the side of the fixed table 103, so that the placement plate 104a is downward and attached to the top of the mounting plate 103b, and attached to the mounting plate 103b through the transparent glass 104b, and the housing is fixed in the fixture 103c, ensuring that in the subsequent welding process, the housing remains firmly inside the fixture 103c until the welding is completed.

[0035] Example 2

[0036] Reference Figure 1 and Figure 2 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0038] Among them, the fixed platform 103 array is arranged around the dividing plate 102, the support plate 103a is fixed on both sides of the fixed platform 103, the top surface of the two support plates 103a is fixed with a mounting plate 103b, and the upper surface of the mounting plate 103b is fixed with a clamp 103c, and the clamp 103c is detachable and replaceable. Different clamps 103c can be selected and replaced according to different sensor shapes. In addition, when the tire pressure sensor housing is placed inside the clamp 103c, the housing is still some distance away from the top of the clamp 103c, so that when the transparent glass 104b above is attached to the top of the clamp 103c, the housing will not be tightly attached to the transparent glass 104b, so as to prevent the housing shell from melting and sticking to the transparent glass 104b during subsequent welding.

[0039] Preferably, a cylinder 104 is disposed on the outer wall of the support plate 103a, a placement plate 104a is disposed at the end of the cylinder 104, and a transparent glass 104b is disposed on the end surface of the placement plate 104a.

[0040] Among them, a cylinder 104 is fixed on the outer surface of the support plates 103a on both sides, and the push column inside the cylinder 104 pushes the placement plate 104a to rise and fall. When the placement plate 104a is raised, it is convenient for the staff to replace the product inside the fixture 103c. When welding is required, the cylinder 104 drives the placement plate 104a to descend. During the descent of the placement plate 104a, the buffer columns 103d on both sides of the mounting plate 103b will buffer the placement plate 104a to prevent the placement plate 104a from directly pressing on the fixture 103c and affecting the product on the fixture 103c. At the same time, the transparent glass 104b above the placement plate 104a is attached to the top of the product, and the light transmittance of the glass is used to enable the laser welding head 201d to weld the product.

[0041] Preferably, a cam divider 105a is provided at the end of the motor 105, a fixing seat 105b is provided at the end of the cam divider 105a, and a mounting seat 105c is provided at the end of the fixing seat 105b.

The dividing plate 102 is driven to rotate by the cam divider 105a, and the fixed platform 103 above is driven to rotate to the bottom of the laser welding head 201d. At the same time, a fixed seat 105b is also arranged below the cam divider 105a. The fixed seat 105b is below the dividing plate 102 and is not fixedly connected to the dividing plate 102. At the same time, a mounting seat 105c is fixed to the lower surface of the fixed seat 105b. The middle of the mounting seat 105c is the support column 202c at the bottom of the air path interactor 202, which supports the air path interactor 202.

[0043] In summary, when in use, the indexing plate 102 is driven to rotate by the cam divider 105a above the motor 105. When the indexing plate 102 rotates, the fixed platform 103 above rotates together. The sensor housing to be welded is first placed inside the fixture 103c, and the sensor housing is fixed in the first step through the groove of the fixture 103c. Then, the fixed platform 103 with the housing placed is rotated away by the cam divider 105a, and a new tire pressure sensor is placed in the fixture 103c above the next fixed platform 103. The sensor shell, for the fixed table 103 that is about to rotate under the laser welding head 201d, the cylinder 104 is used in advance to make the upper placement plate 104a drop down, and the transparent glass 104b stops above the fixture 103c, close to the product, and the product is further confined inside the fixture 103c. Then the fixed table 103 is rotated to under the laser welding head 201d to weld the product. The welded product is rotated with the fixed table 103 and is taken away by the staff, and the new shell is placed inside the empty fixture 103c.
