Description

Technical Field

[0001] This utility model relates to the field of sensor processing technology, and in particular to a welding device for sensor processing. Background Technology

[0002] A sensor is a detection device that can sense the information being measured and transform that information into an electrical signal or other required form of information output according to a certain rule, in order to meet the requirements of information transmission, processing, storage, display, recording, and control. In the manufacturing process of sensors, welding is one of the key steps. The quality of the welding directly affects the performance and reliability of the sensor.

[0003] Currently, existing welding equipment for sensor processing has several problems: Firstly, before welding, dust, debris, and other impurities often adhere to the surface of the sensor substrate. These impurities affect the weld's strength and conductivity, leading to issues such as incomplete welds and detachment, thus reducing product yield. Secondly, the welding process generates a large amount of heat. If the substrate cannot be cooled promptly after welding, excessively high temperatures may cause deformation or even damage to the sensitive components and circuit structures on the substrate, affecting the sensor's performance and lifespan. Therefore, there is an urgent need for welding equipment for sensor processing that can effectively clean the substrate before welding and achieve rapid cooling after welding. Utility Model Content

[0027] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0028] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Please see Figure 1-6 This utility model provides a welding device for sensor processing, comprising:

[0031] Base 1;

[0032] Four brackets 2 are fixedly installed at the four corners of the upper outer wall of the base 1.

[0033] The three-axis moving module 3 is mounted on the bracket 2 and has a welding head 31.

[0034] Fixing base 4 is fixedly installed on the upper outer wall of base 1;

[0035] Dust removal mechanism 5 is installed in the fixed base 4 and is used to clean and remove dust from the sensor substrate.

[0036] Cooling mechanism 6 is located on top of the fixed base 4 and is used to quickly cool the sensor substrate after welding.

[0037] The above structure enables the welding of sensor components to the substrate and improves the welding quality.

[0038] It should be noted that the three-axis moving module 3 is used to drive the welding head 31 to move precisely in three axes and perform fine position control. Both the three-axis moving module 3 and the welding head 31 are mature existing technologies and are common knowledge in the field. The structure and principle will not be described in detail here.

[0039] The dust removal mechanism 5 includes a motor 51, which is mounted on one outer wall of the fixed base 4. The output shaft of the motor 51 extends into the fixed base 4 and is fixedly connected to a reciprocating screw 52. Two symmetrically distributed guide rods are fixedly connected between the inner walls of the two sides of the fixed base 4. A movable seat 53 that cooperates with the reciprocating screw 52 is slidably sleeved on the guide rod. A hollow plate 54 is fixedly connected to one side wall of the movable seat 53. Several bristles 55 and through holes 57 are evenly arranged on the lower outer wall of the hollow plate 54. An air extraction pipe 56 is connected to the hollow plate 54, and the other end of the air extraction pipe 56 is connected to an external vacuum cleaner.

[0040] With the above-mentioned structure, the sensor substrate can be cleaned before welding, and impurities can be removed during the cleaning process. This effectively removes impurities from the substrate surface, improves welding quality, reduces the occurrence of problems such as poor welding and desoldering, and increases the product qualification rate.

[0041] The cooling mechanism 6 includes a support column 61, which is fixedly mounted on the upper outer wall of the fixed base 4. The upper end of the support column 61 is fixedly connected to a housing 62. An electric cooling chip 63 is embedded on one side wall of the housing 62. A heat exchanger 64 is provided on the cold side of the electric cooling chip 63. Two symmetrically distributed fans 65 are installed on one side inner wall of the housing 62. Several serpentine temperature conduction grooves 66 are opened in the heat exchanger 64.

[0042] The above-described structure enables the sensor substrate to cool down rapidly after welding, preventing deformation or damage to the sensitive elements and circuit structure on the substrate due to high temperature, thus ensuring the performance and service life of the sensor.

[0043] The base 1 has a suction cup 11 at the center of the upper side wall, a vacuum generator 12 inside the base 1, and a connecting pipe 13 connecting the suction cup 11 and the suction port of the vacuum generator 12.

[0044] The above structure enables the sensor substrate to be positioned, ensuring stability during welding.

[0045] The hot surface of the electric cooling chip 63 is provided with heat dissipation fins 621, and a cooling fan is installed on the heat dissipation fins 621. When the electric cooling chip 63 is working, the heat generated is conducted to the heat dissipation fins 621 through the hot surface, and the cooling fan dissipates heat from the heat dissipation fins 621.

[0046] A filter screen 622 is embedded on one side wall of the housing 62 at the position corresponding to the fan 65 to prevent dust from being blown onto the sensor substrate.

[0047] It should be noted that this utility model is a welding device for sensor processing. In use, the sensor substrate to be welded is placed on the suction cup 11, and then the vacuum generator 12 is started. A vacuum is created between the suction cup 11 and the substrate using the connecting pipe 13, thus fixing the substrate in place. Then, the motor 51 and the vacuum cleaner are started. The output shaft of the motor 51 drives the reciprocating screw 52 to rotate. The reciprocating screw 52 has two threaded grooves with the same pitch but opposite directions. The moving seat 53 is equipped with a slider that matches the threaded grooves. The rotation of the reciprocating screw 52 causes the side of the spiral groove to push the slider placed in the spiral groove to perform axial reciprocating motion. This allows the reciprocating screw 52 to continuously reciprocate without changing its direction of rotation, enabling the moving seat 53 to move continuously. The movement of the moving seat 53 drives the hollow plate 54 to move, and the brush 55 reciprocates by cleaning the substrate. Under the action of the vacuum cleaner, a vacuum is generated inside the hollow plate 54. Under negative pressure, the cleaned impurities enter the hollow plate 54 through the through hole 57, and then enter the dust bag of the vacuum cleaner through the suction pipe 56. After cleaning, the sensor element and the substrate are welded using the welding head 31. After welding, the fan 65 draws air into the housing 62. Under the action of the electric cooling chip 63, the temperature of the heat exchanger 64 decreases, and the air enters the serpentine temperature conduction groove 66 to exchange heat with the heat exchanger 64 and become cold air. The serpentine temperature conduction groove 66 increases the contact time between the air and the heat exchanger 64, ensuring that the temperature of the air entering the housing 62 can be reduced to cold air. The air after heat exchange is blown onto the welded sensor substrate by the fan 65 to cool the substrate quickly, preventing the sensor substrate from deforming or damaging the sensitive elements and circuit structure on the substrate due to high temperature. After cooling, the vacuum generator 12 is turned off, and the substrate can be removed.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
