Description

Technical Field

[0001] This invention relates to the field of temperature sensor welding, specifically to a welding apparatus for temperature sensor production. Background Technology

[0002] A temperature sensor is a sensor that senses temperature and converts it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments, and there are many types. Based on the measurement method, they can be divided into two main categories: contact and non-contact. Based on the sensor material and electronic component characteristics, they are divided into resistance temperature detectors (RTDs) and thermocouples. A temperature sensor mainly consists of components and a housing. The housing prevents physical damage, dust, moisture, and other contaminants from entering, ensuring the normal operation of the sensor's internal circuitry. The housing also shields against electromagnetic interference, reducing the interference of external electromagnetic fields on the sensor signal and improving measurement accuracy. Therefore, the temperature sensor housing plays a crucial role in protecting internal components and ensuring measurement accuracy and stability. A cylindrical housing is one of the most common shapes. This shape offers good symmetry and stability, facilitates installation and fixation, and is suitable for most applications.

[0003] In the production process of temperature sensors, the housings of temperature sensors are usually connected by welding. This is because temperature sensor housings connected by welding have better sealing performance, which can effectively prevent dust and moisture from entering and damaging the internal components. In addition, welding enhances the structural strength of temperature sensor housings, making them more resistant to mechanical stresses such as vibration and impact. Welding also reduces seams and gaps, making them suitable for different usage environments. However, welding temperature sensors requires the use of welding equipment.

[0004] The welding device for the temperature sensor housing typically consists of a clamp, a drive mechanism, and a welding mechanism. The clamp fixes the temperature sensor housing, the welding mechanism welds the temperature sensor housing, and the drive mechanism rotates the clamp so that the welding torch welds different positions on the temperature sensor housing.

[0005] During use, the radius of temperature sensors varied depending on their application requirements. Therefore, when welding the housings of temperature sensors with different radii, it was necessary to adjust the distance between the welding torch and the housing to maintain the optimal welding distance. This method was particularly time-consuming when the production line frequently changed housing specifications. Furthermore, the housings could become contaminated with dust during processing, transportation, or storage, and dust in the welding environment could also settle on the workpiece surface. Dust and impurities could scatter and absorb laser energy, resulting in insufficient laser energy in the welding area, which would prevent the material from melting sufficiently, leading to weak welds and incomplete welds. Based on these issues, this application proposes a welding device for temperature sensor production. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a welding device for temperature sensor production, which has advantages such as adaptive adjustment of the distance between the welding torch and the housing, cleaning of dust on the housing, and continuous welding of the housing.

[0021] Compared with the prior art, the present invention provides a welding apparatus for the production of temperature sensors, which has the following advantages:

[0022] 1. This welding device for temperature sensor production allows for adjustment of the laser welding gun position via an adaptive welding component. The adaptive welding component adjusts the position based on the radius of the temperature sensor housing, avoiding the need to adjust the distance between the laser welding gun and the temperature sensor housing when welding different housings. This maintains an optimal welding distance between the laser welding gun and the temperature sensor housing, preventing a decrease in welding quality due to excessively close or far distances. It also avoids the need for significant time-consuming laser welding gun adjustments when frequent housing specification changes are required on the production line.

[0023] 2. This welding device for producing temperature sensors can clean the dust on the temperature sensor housing through an adaptive dust removal component and collect the cleaned dust. At the same time, the adaptive dust removal component can adjust the position of the dust suction hood and the cleaning brush according to the radius of the temperature sensor housing, so that the dust suction hood maintains a suitable distance from the temperature sensor housing and the cleaning brush is always in contact with the temperature sensor housing. This facilitates the cleaning of dust on the temperature sensor housing and avoids the problem of dust and impurities scattering and absorbing laser energy, which would lead to weak welding and poor solder joints.

[0024] 3. This welding device for producing temperature sensors, through connecting components and transmission components, enables a servo motor to rotate forward, driving a rotating shaft to rotate, which in turn moves a fixed frame. The fixed frame moves the housing through a housing positioning component. However, the servo motor cannot drive the rotating cylinder and connecting cylinder to rotate through the transmission component. When the servo motor rotates in reverse, it drives the rotating cylinder and connecting cylinder to rotate through the transmission component, but the servo motor cannot drive the rotating shaft to rotate through the connecting component. Thus, a single servo motor can move the temperature sensor housing to the dust removal and welding position and enable the temperature sensor housing to rotate on its own.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a welding apparatus for the production of temperature sensors.

[0037] In one typical implementation of this application, such as Figure 1-3 As shown, a welding apparatus for manufacturing temperature sensors includes:

[0038] Mounting base 1, U-shaped plate 2 is fixedly installed at the bottom of mounting base 1, servo motor 3 is fixedly installed at the bottom of U-shaped plate 2, rotating shaft 4 is rotatable inside mounting base 1, connecting component 13 is provided between the bottom end of rotating shaft 4 and the top of the output end of servo motor 3, fixing bracket 6 is fixedly installed at the top of rotating shaft 4, rotating cylinder 8 and connecting cylinder 9 are rotatable inside mounting base 1, and driving gear 5 is fixedly installed at the top of rotating cylinder 8 and connecting cylinder 9.

[0039] The housing positioning component 7 is disposed inside the fixing frame 6 and is used to fix the housing of the temperature sensor.

[0040] Transmission component 10 is disposed inside the mounting base 1 and is used by servo motor 3 to drive rotating cylinder 8 and connecting cylinder 9 to rotate.

[0041] An adaptive dust removal component 11 is disposed on the left side of the mounting base 1 and is used to clean the dust on the housing of the temperature sensor.

[0042] Adaptive welding component 12 is disposed on the rear side of mounting base 1 and is used to weld the temperature sensor housing.

[0043] As a preferred embodiment in this example, refer to Figure 5As shown, the connecting component 13 includes a rotating shaft 131, which is fixedly mounted on the output end of the servo motor 3. A rotating disk 132 is fixedly mounted on the top of the rotating shaft 131, and a one-way push block 133 is fixedly mounted on the top of the rotating disk 132. A connecting housing 134 is overlapped on the surface of the rotating disk 132 and is fixedly mounted on the bottom end of the rotating shaft 4. A sealing plate 135 is fixedly mounted on the bottom of the connecting housing 134, and the sealing plate 135 is rotatably connected to the rotating shaft 131. A vertical spring 136 is fixedly installed on the upper side wall of the 4th wall. A movable disc 137 is fixedly installed at the bottom of the vertical spring 136. A rectangular groove is provided through the top of the movable disc 137. A rectangular column is slidably installed inside the rectangular groove. The rectangular column is fixedly installed on the upper side wall of the connecting housing 134. A connecting block 138 is fixedly installed at the bottom of the movable disc 137. There are several unidirectional pushing blocks 133 and several connecting blocks 138, and the several unidirectional pushing blocks 133 and several connecting blocks 138 are distributed in a circular array. One side of the connecting housing 134 is a sloping surface, and the other side of the connecting block 138 is an arc-shaped surface. The connecting block 138 overlaps with the one-way pushing block 133. The servo motor 3 drives the rotating disk 132 to rotate through the rotating shaft 131, causing the one-way pushing block 133 to push the moving disk 137 to rotate through the connecting block 138. This causes the connecting block 138 to drive the connecting housing 134 to rotate through the rectangular groove and rectangular column, and causes the rotating shaft 4 to drive the fixing frame 6 to rotate. The fixing frame 6 drives the temperature sensor housing to move through the housing positioning component 7, thereby making the temperature sensor housing move. When the sensor housing moves to the dust removal and welding position, and the servo motor 3 drives the rotating cylinder 8 and the connecting cylinder 9 to rotate through the transmission component 10, the rotating shaft 131 drives the one-way push block 133 to move in the opposite direction through the rotating disk 132, so that the one-way push block 133 pushes the moving disk 137 to compress the vertical spring 136 through the connecting block 138. Then the connecting housing 134 will not drive the rotating shaft 4 to rotate, so that the forward and reverse rotation of the servo motor 3 can drive the rotating shaft 4, the rotating cylinder 8 and the connecting cylinder 9 to rotate respectively.

[0044] As a preferred embodiment in this example, refer to Figure 4As shown, the outer casing positioning component 7 includes a rotating shaft 71 and an electric push rod 72. The rotating shaft 71 is rotatably mounted inside the fixed frame 6, and the electric push rod 72 is fixedly mounted on the top of the fixed frame 6. A connecting gear 73 is fixedly mounted on the surface of the rotating shaft 71. A supporting ball bearing 74 is overlapped inside the rotating shaft 71, and a limiting plate 75 is overlapped on the surface of the supporting ball bearing 74. The limiting plate 75 is fixedly mounted on the bottom end of the rotating shaft 71. A mounting housing 76 is fixedly mounted on the top of the rotating shaft 71. A rotating screw 77 is rotatably mounted inside the mounting housing 76. A threaded sleeve 78 is threaded on the surface of the rotating screw 77. Connecting posts 79 are fixedly mounted on both sides of the threaded sleeve 78. A clamping block 710 is fixedly mounted on the top of the connecting post 79. A fixed seat 711 is mounted on the output end of the electric push rod 72 via a bearing. A top block 712 is fixedly mounted on the bottom of the fixed seat 711. The metal to be welded is then placed on the fixed seat 711. The outer casing is placed on top of the mounting housing 76. By rotating the screw 77, the screw sleeve 78 drives the clamping block 710 through the connecting column 79 to fix the temperature sensor outer casing. The other end of the outer casing that needs to be welded is connected to the fixed outer casing. The electric push rod 72 pushes the top block 712 to contact the outer casing through the bearing and the fixing seat 711, thereby fixing the outer casing. When the drive gear 5 rotates, the connecting gear 73 rotates through the rotating shaft 71. The rotating shaft 71 drives the clamping block 710 through the mounting housing 76 and the connecting column 79, causing the clamping block 710 to drive the temperature sensor outer casing to rotate. The temperature sensor outer casing drives the fixing seat 711 to rotate through the bearing via the top block 712. The rotation of the temperature sensor outer casing facilitates the thorough dust removal and welding of the temperature sensor outer casing, avoiding the situation where the temperature sensor outer casing is not thoroughly dusted and the welding is incomplete.

[0045] As a preferred embodiment in this example, refer to Figures 6 to 7As shown, the transmission component 10 includes a drive transmission wheel 101, which is fixedly mounted on the output end of the servo motor 3. A transmission belt 102 is meshed inside the drive transmission wheel 101, and a driven transmission wheel 103 is meshed inside the transmission belt 102. Two circular columns 1012 are overlapped inside the driven transmission wheel 103. The two circular columns 1012 are fixedly mounted on the bottom end of the rotating column 8 and the bottom end of the connecting column 9, respectively. A mounting sleeve 104 is fixedly mounted on the top of the driven transmission wheel 103. The mounting sleeve 104 is connected to the circular column 1012. 12. The mounting sleeve 104 has a rotatable limiting ring 105 inside, which is fixedly installed on the surface of the circular column 1012. A pushing column 106 is fixedly installed on the outer surface of the mounting sleeve 104. A pushing sleeve 107 is overlapped on the outer surface of the mounting sleeve 104. A movable sleeve 108 is fixedly installed on the top of the pushing sleeve 107. A limiting protrusion 109 is slidably installed inside the movable sleeve 108, which is fixedly installed on the surface of the circular column 1012. A movable plate 1010 is rotatably installed on the surface of the movable sleeve 108. A hydraulic push rod 1 is installed on the top of the movable plate 1010. 011, the hydraulic push rod 1011 is fixedly installed on the top of the mounting base 1, and the output end of the hydraulic push rod 1011 is fixedly connected to the moving plate 1010. The hydraulic push rod 1011 drives the pushing sleeve 107 to move downward through the moving plate 1010 and the moving sleeve 108, so that the pushing column 106 is inserted into the pushing sleeve 107. At this time, the servo motor 3 drives the mounting sleeve 104 to rotate through the active transmission wheel 101, the transmission belt 102 and the driven transmission wheel 103. The mounting sleeve 104 drives the pushing sleeve 107 to rotate inside the moving plate 1010 through the pushing column 106. 7. The limiting protrusion 109 and the circular column 1012 drive the rotating cylinder 8 and the connecting cylinder 9 to rotate, thereby causing the drive gear 5 to drive the connecting gear 73 to rotate, and causing the housing positioning component 7 to drive the temperature sensor housing to rotate. During the rotation of the drive rotating shaft 4, the push sleeve 107 separates from the push column 106, so the driven transmission wheel 103 cannot drive the push sleeve 107 to rotate through the mounting sleeve 104 and the push column 106, thereby causing the rotating cylinder 8 and the connecting cylinder 9 to not rotate. The rotation or non-rotation of the rotating cylinder 8 and the connecting cylinder 9 can be controlled by the forward and reverse rotation of the servo motor 3.

[0046] As a preferred embodiment in this example, refer to Figures 8 to 9As shown, the adaptive dust removal component 11 includes a mounting vertical plate 111, which is fixedly mounted on the left side of the mounting base 1. An adjusting rod 112 is slidably disposed inside the mounting vertical plate 111. A connecting circular plate 113 is fixedly disposed at the left end of the adjusting rod 112. A spring 114 connects the right side of the connecting circular plate 113 to the left side of the mounting vertical plate 111. An arc-shaped plate 115 is fixedly disposed at the right end of the adjusting rod 112. An adjusting ball 116 is overlapped inside the arc-shaped plate 115. Both the arc-shaped plate 115 and the arc-shaped plate 116 are arc-shaped metal plates. There are several adjusting balls 116 and 126, both of which are metal balls. The surface of the adjusting ball 116 overlaps... A limiting arc plate 117 is fixedly installed on the side of the arc plate 115 away from the adjusting rod 112. A mounting plate 118 is fixedly installed on the surface of the adjusting rod 112. A dust suction pipe 119 is fixedly installed inside the mounting plate 118. The dust suction pipe 119 is slidably installed inside the mounting vertical plate 111. A dust suction hood 1110 is fixedly installed at the right end of the dust suction pipe 119. A cleaning brush 1111 is fixedly installed inside the dust suction hood 1110. The adaptive welding component 12 includes a fixed vertical plate 121, which is fixedly installed on the rear side of the mounting base 1. A moving rod 122 is slidably installed inside the fixed vertical plate 121. A moving circular plate 123 is fixedly installed at the rear end of the moving rod 122. The front side of the moving circular plate 123 is connected to the rear side of the fixed vertical plate 121. A spring 124 connects the two sides. An arc-shaped plate 125 is fixedly installed at the front end of the moving rod 122. An adjusting ball 126 is overlapped inside the arc-shaped plate 125. A limiting arc plate 127 is overlapped on the surface of the adjusting ball 126. The limiting arc plate 127 is fixedly installed on the side of the arc-shaped plate 125 away from the moving rod 122. A connecting plate 128 is fixedly installed on the surface of the moving rod 122. A smoke extraction tube 129 and a laser welding gun 1210 are fixedly installed inside the connecting plate 128. The smoke extraction tube 129 is slidably installed inside the fixed vertical plate 121. The temperature sensor housing can push the arc-shaped plate 115 and the arc-shaped plate 125 to move through the adjusting ball 116 and the adjusting ball 126, so that the arc-shaped plate 115 and the arc-shaped plate 125 can move. 125 uses adjusting rod 112 and moving rod 122 to drive connecting circular plate 113 and moving circular plate 123 to stretch spring 114 and spring 124. Adjusting rod 112 moves suction pipe 119 via mounting plate 118, causing suction hood 1110 to move cleaning brush 1111. Moving rod 122 moves smoke extraction pipe 129 and laser welding gun 1210 via connecting plate 128, allowing the positions of smoke extraction pipe 129 and laser welding gun 1210 to be adjusted according to the radius of the temperature sensor housing. This also allows suction hood 1110 and cleaning brush 1111 to be adjusted according to the radius of the temperature sensor housing, thus eliminating the need for manual adjustment and enabling adaptive adjustment based on the radius of the temperature sensor housing.This avoids the adjustment process taking too much time.

[0047] Working principle of the invention: In use, the metal shell to be welded is placed on top of the mounting housing 76. The screw 77 is rotated to drive the screw sleeve 78 to move. The screw sleeve 78, through the connecting post 79, drives the clamping block 710 to contact the temperature sensor shell, connecting the other end of the shell to be welded to the fixed shell. The output end is extended by the electric push rod 72, causing the electric push rod 72 to drive the fixed seat 711 downwards via the bearing. The fixed seat 711 pushes the top block 712 to contact the shell. Then, the servo motor 3 drives the output end to rotate the rotating shaft 131, causing the rotating shaft 131 to rotate the rotating disk 132. The rotating disk 132 drives the one-way pushing block 133 to move, causing the vertical surface of the one-way pushing block 133 to push the connecting block 1. The vertical surface of 38 allows the unidirectional push block 133 to push the moving disk 137 to rotate via the connecting block 138. This causes the connecting block 138 to rotate the connecting housing 134 via the rectangular groove and rectangular column, which in turn drives the rotating shaft 4 to rotate. The rotating shaft 4 then drives the fixed frame 6 to rotate, which in turn drives the rotating shaft 71 and the electric push rod 72 to move. The rotating shaft 71 then drives the mounting housing 76 to move, which in turn drives the clamping block 710 to move via the connecting column 79. Simultaneously, the electric push rod 72 drives the fixed seat 711 to move via the bearing, which in turn drives the top block 712 to move. This, in turn, causes the top block 712 and the clamping block 710 to move the temperature sensor housing. During this process, the push sleeve 107 separates from the push column 106. If the driven transmission wheel 103 cannot drive the push sleeve 107 to rotate via the mounting sleeve 104 and the push column 106, then the push sleeve 107 cannot drive the circular column 1012 to rotate via the moving sleeve 108 and the limiting protrusion 109. This prevents the rotating column 8 and the connecting column 9 from rotating. When the temperature sensor housing contacts the adjusting ball 116, the temperature sensor housing pushes the arc plate 115 to the left via the adjusting ball 116. This causes the arc plate 115 to stretch the spring 114 via the adjusting rod 112, which in turn drives the connecting plate 113. The adjusting rod 112 then drives the suction pipe 119 to slide inside the mounting vertical plate 111 via the mounting plate 118, and through the suction pipe 119, drives the dust hood 1110 to move to the left, causing the dust hood 1110 to... 110 drives the cleaning brush 1111 to move to the left, causing the dust cover 1110 and the cleaning brush 1111 to adjust according to the radius of the temperature sensor housing. When the dust-cleaning housing moves to the rear, it pushes the arc plate 125 to the rear via the adjusting ball 126. The arc plate 125 then drives the moving circular plate 123 via the moving rod 122 to stretch the spring 124. The moving rod 122 moves the smoke pipe 129 and the laser welding gun 1210 via the connecting plate 128 to the rear, causing the positions of the smoke pipe 129 and the laser welding gun 1210 to adjust according to the radius of the temperature sensor housing. When the temperature sensor housing contacts the adjusting ball 116 and the adjusting ball 126 in the middle, the servo motor 3 stops running.At this time, the hydraulic push rod 1011 drives the output end to move the moving plate 1010 downward, causing the moving plate 1010 to drive the moving sleeve 108 downward. The moving sleeve 108 pushes the pushing sleeve 107 downward, causing the pushing column 106 to insert into the pushing sleeve 107. At this time, the servo motor 3 drives the output end to reverse, causing the active transmission wheel 101 to drive the driven transmission wheel 103 to rotate through the transmission belt 102, and the driven transmission wheel 103 to drive the mounting sleeve 104 to rotate. The mounting sleeve 104 drives the pushing sleeve 107 to rotate inside the moving plate 1010 through the pushing column 106. The pushing sleeve 107 drives the circular column 1012 to rotate through the limiting protrusion 109, causing the circular column 1012 to drive the rotating cylinder 8 and the connecting cylinder 9 to rotate. The rotating cylinder 8 and the connecting cylinder 9 simultaneously drive the drive gear 5 to rotate, and the drive gear 5 drives the connecting gear 73 to rotate, causing the connecting gear 73 to drive the rotating shaft 71 to rotate. The rotating shaft 71 drives the mounting shell. The body 76 rotates, and the mounting housing 76 drives the clamping block 710 to rotate via the connecting column 79. This causes the clamping block 710 to rotate the temperature sensor housing. The temperature sensor housing, via the top block 712, drives the fixing seat 711 to rotate via bearings. While the temperature sensor housing rotates, the cleaning brush 1111 sweeps away dust from the housing, and the dust is then removed by the suction pipe 119 and the suction hood 1110. Meanwhile, the laser welding gun 1210 welds the temperature sensor housing, and the fume generated during welding is removed by the fume extraction pipe 129. During this process, the rotating shaft 131 drives the one-way pushing block 133 to move in the opposite direction via the rotating disk 132. This causes the inclined surface of the one-way pushing block 133 to contact the arc-shaped surface of the connecting block 138, pushing the connecting block 138 upwards. This causes the connecting block 138 to push the moving disk 137 to compress the vertical spring 136, preventing the connecting housing 134 from rotating the rotating shaft 4.
