Description

Technical Field

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

[0002] Cold spraying is an advanced surface treatment process that involves spraying metallic or non-metallic powders at supersonic speeds onto a substrate surface at room temperature or low temperature to form a dense, uniform coating. This technology is widely used in electronics, aerospace, and automotive industries, and is particularly effective in the surface treatment of wiring terminals, significantly improving their conductivity, corrosion resistance, and abrasion resistance.

[0003] In existing technical solutions, traditional spraying equipment generally consists of a spray gun, a fixed bracket, and a material placement platform. When using this equipment to spray coatings on wire terminals, operators must manually place the wire terminals on the material placement platform and fix them in position using the fixed bracket, then operate the spray gun to spray the surface of the wire terminals. However, this traditional production process has many drawbacks. Because the wire terminals are placed manually and there is no material changing mechanism, the machine needs to be stopped for a long time to change materials after the wire terminals are sprayed. This results in low production efficiency and high production costs for wire terminals. Therefore, a cold spraying processing device is needed to improve the production efficiency and reduce the production cost of wire terminals. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a cold spraying processing device, which solves the technical problems of low production efficiency and high production cost of wire terminals.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A cold spray coating apparatus is used to spray a coating onto the surface of a wiring terminal. The apparatus has a spraying station and a material changing station at both ends, and includes:

[0007] A cold spray assembly, wherein the cold spray assembly is disposed at the spraying station;

[0008] A pair of stacking fixtures, the stacking fixtures being used to store connecting terminals;

[0009] A material conveying assembly for alternately transferring a pair of material handling fixtures between a spraying station and a material changing station;

[0010] A movable baffle is provided between the spraying station and the material changing station;

[0011] A dust collection assembly for collecting dust generated during the cold spraying process.

[0012] Based on the above structure, the principle of the cold spraying processing device is as follows: the cold spraying component is located at the spraying station, which can accurately spray the coating material onto the surface of the wiring terminals, ensuring uniform coating thickness and stable quality, and meeting the performance requirements of the wiring terminals in terms of electrical connection, etc.; through paired material handling fixtures and conveying components, the pair of material handling fixtures can be alternately switched between the spraying station and the material changing station. When one material handling fixture is performing spraying operations at the spraying station, the other can prepare the next batch of wiring terminals to be sprayed in advance at the material changing station, greatly shortening the overall processing time and improving production efficiency; The baffle is installed between the spraying station and the material changing station, effectively isolating the two work areas. On the one hand, it prevents dust from spreading from the spraying process to the material changing station, avoiding dust contamination of new terminals to be processed; on the other hand, it blocks external impurities from entering the spraying station during material changing, ensuring the purity of the spraying environment and reducing the defect rate. The dust collection component collects the dust that is inevitably generated during the cold spraying process, maintaining the cleanliness of the work area and preventing dust accumulation from damaging the equipment, such as blocking ventilation openings or affecting the movement of mechanical parts. It also prevents dust from being inhaled by operators, ensuring the air quality of the working environment.

[0013] Furthermore, in this application, a cold spraying processing apparatus includes a cold spraying component comprising a cold spray head and a robotic arm, wherein the actuator of the robotic arm is connected to the cold spray head. As a preferred embodiment of this application, in this cold spraying processing apparatus, the robotic arm serves as a key component connecting the cold spray head to the main body of the apparatus, and its actuator is connected to the cold spray head, providing the cold spray head with multi-degree-of-freedom movement capabilities.

[0014] Furthermore, in a cold spray coating apparatus of this application, the material placement fixture includes a base plate, on which a set of support components are provided. These support components are spaced apart along the X-direction. Each support component includes a first support platform and a second support platform, the upper surfaces of which respectively abut against the connecting terminals in the Z-direction. As a preferred embodiment of this application, in the cold spray coating apparatus, the base plate of the material placement fixture serves as a basic load-bearing component, providing a stable platform for the entire support structure. A set of support components spaced apart along the X-direction are distributed on it, wherein the upper surfaces of the first and second support platforms respectively abut against the connecting terminals in the Z-direction. This precisely supports the connecting terminals from multiple points, effectively preventing the terminals from shaking or shifting during placement, transportation, and spraying. This ensures that the cold spray coating operation can accurately act on the predetermined surface of the terminals, avoiding spraying deviations or defective products caused by terminal displacement.

[0015] Furthermore, in a cold spray coating apparatus of this application, both the first and second support platforms are provided with positioning protrusions. These positioning protrusions are used to limit the connecting terminals to the support assembly in the X and Y directions. As a preferred embodiment of this application, in a cold spray coating apparatus, the positioning protrusions on the first and second support platforms limit the connecting terminals in the X and Y directions. Working in conjunction with the bearing surface of the support platform itself, they form a precise two-dimensional constraint system for the connecting terminals. When the connecting terminals are placed on the support assembly, the positioning protrusions can quickly engage the corresponding edges or preset positioning positions of the terminals, ensuring that the terminals are fixed in position on the horizontal plane and preventing translation and rotation in the X and Y directions, thus providing a guarantee for subsequent precise spraying.

[0016] Furthermore, in a cold spray coating apparatus of this application, the material handling fixture further includes a pressure plate, which is detachably mounted on a set of first support platforms. The pressure plate has a set of spray nozzles, each corresponding to a set of terminal blocks to be coated. As a preferred embodiment of this application, in this cold spray coating apparatus, the pressure plate is detachably mounted on a set of first support platforms, forming an upper and lower clamping structure with the lower support platform, further securing the terminal blocks and ensuring each terminal is accurately maintained in the preset coating position. The set of spray nozzles on the pressure plate corresponds one-to-one with the terminal blocks to be coated, exposing only the areas requiring coating, preventing accidental spraying of cold spray paint onto other untreated areas of the terminal. This saves paint consumption and prevents excess paint from accumulating on the terminal surface, affecting electrical performance or subsequent assembly, thus improving the precision of the spray coating process.

[0017] Furthermore, in a cold spraying processing apparatus of this application, the material conveying component includes: a track, a slider, and a driving device. The track connects the spraying station and the material changing station. The slider is slidably mounted on the track. The driving device is used to drive the slider to slide and adjust on the track. The base plate is mounted on the slider. As a preferred embodiment of this application, in a cold spraying processing apparatus, the track connecting the spraying station and the material changing station provides a precise and stable guiding path for the movement of the slider. The slider, slidably mounted on the track, can smoothly slide along a predetermined route. With the assistance of the driving device to adjust the slider's sliding motion, the slider with the base plate mounted can be precisely conveyed to the designated station.

[0018] Furthermore, the cold spray coating apparatus of this application further includes: a protective cover, which is installed on the material changing station. A linear drive device is installed inside the protective cover, with its fixed end mounted on the inner wall of the protective cover and its telescopic end connected to a movable baffle. As a preferred embodiment of this application, the protective cover installed on the material changing station in the cold spray coating apparatus of this application can form a relatively independent enclosed area in space, effectively isolating the material changing operation from the external environment. On the one hand, it can prevent dust, impurities, and other foreign objects from entering the material changing station, avoiding contamination of the terminals to be sprayed and ensuring the cleanliness of the processed materials; on the other hand, it can also prevent small amounts of debris and particles that may be generated during the material changing process from spreading to other areas of the workshop, maintaining the cleanliness of the entire production environment.

[0019] Furthermore, in a cold spray coating apparatus of this application, the dust collection component includes: an open-top trough, a set of connecting pipes, and a dust collection box. The trough is disposed at the spraying station, and the set of connecting pipes connects the trough and the dust collection box. The bottom of the trough has through holes corresponding to a set of spraying ports. When the material handling fixture is located at the spraying station, the through holes and the spraying ports are axially connected. As a preferred embodiment of this application, in a cold spray coating apparatus, the trough in the dust collection component is disposed at the spraying station, and its bottom has through holes corresponding to the spraying ports. When the material handling fixture is located at the spraying station, the two are axially connected. When the terminal is sprayed through the through holes and the spraying ports, residual paint will accumulate in the trough and enter the dust collection box through the connecting pipes, preventing dust from spreading around the spraying station, keeping the entire work area clean and tidy, creating a good working environment for operators, and reducing the respiratory hazards of dust to operators.

[0020] Furthermore, in this application, a cold spraying processing apparatus includes a set of rollers and an adjusting seat at its lower end. As a preferred embodiment of this application, the set of rollers enables the cold spraying processing apparatus to move. The adjusting seat cooperates with the rollers; after the equipment is pushed to the desired position by the rollers, the adjusting seat can be used for fine-tuning of the position and leveling.

[0021] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0022] This invention provides a cold spray coating processing device. By setting up a spraying station and a material changing station at both ends of the device, and equipping it with a cold spray component, paired material handling fixtures, a material conveying component, a movable baffle, and a dust collection component, it solves the problems of low spraying efficiency, unstable coating quality, inconvenient material changing, and dust pollution in the existing terminal block spraying process. The robotic arm in the cold spray component works in conjunction with the cold spray head to achieve precise and flexible spraying of terminals of different shapes; the paired material handling fixture and its fine structure ensure stable placement of terminals and rapid material changing during processing; the material conveying component uses tracks, sliders, and a drive device to ensure smooth and efficient material transfer; the movable baffle, with the cooperation of a protective cover and a linear drive device, flexibly separates the workstations to avoid cross-contamination; and the dust collection component collects dust in a timely manner, creating a clean processing environment, thus comprehensively improving the quality and efficiency of cold spray coating processing of terminal blocks.

Detailed Implementation

[0029] like Figure 1 , 2As shown, a cold spray coating processing device is used to spray a coating onto the surface of a wiring terminal. The device has a spraying station and a material changing station at both ends, and includes: a cold spray assembly 1, which is disposed at the spraying station; a pair of material handling fixtures 2, which are used to receive the wiring terminals; a material conveying assembly 3, which is used to alternately transfer the pair of material handling fixtures 2 between the spraying station and the material changing station; a movable baffle 4, which is disposed between the spraying station and the material changing station; and a dust collection assembly 5, which is used to collect dust generated during the cold spraying process.

[0030] Based on the above structure, the principle of the cold spraying processing device is as follows: the cold spraying component 1 is located at the spraying station and can accurately spray the coating material onto the surface of the wiring terminal, ensuring uniform coating thickness and stable quality, and meeting the performance requirements of the wiring terminal in terms of electrical connection, etc.; through the paired material handling fixtures 2 and the material conveying component 3, the pair of material handling fixtures 2 can be switched alternately between the spraying station and the material changing station. When one material handling fixture 2 is performing spraying operation at the spraying station, the other can prepare the next batch of wiring terminals to be sprayed in advance at the material changing station, which greatly shortens the overall processing time and improves production efficiency. The movable baffle 4 is installed between the spraying station and the material changing station, effectively isolating the two working areas. On the one hand, it prevents dust from spreading to the material changing station during the spraying process, avoiding dust contamination of the new wiring terminals to be processed; on the other hand, it blocks external impurities from entering the spraying station during material changing, ensuring the purity of the spraying environment and reducing the defect rate. The dust collection component 5 collects the dust that is inevitably generated during the cold spraying process, which not only keeps the working area clean and hygienic, but also prevents dust accumulation from damaging the equipment, such as blocking the ventilation openings and affecting the movement of mechanical parts, but also prevents the dust from being inhaled by the operators, ensuring the air quality of the working environment.

[0031] In this embodiment, the cold spray assembly 1 includes a cold spray head 11 and a robotic arm 12, wherein the actuator of the robotic arm 12 is connected to the cold spray head 11. As a key component connecting the cold spray head 11 to the main body of the device, the robotic arm 12, with its actuator connected to the cold spray head 11, endows the cold spray head 11 with multi-degree-of-freedom motion capabilities.

[0032] like Figure 4As shown, in this embodiment, the material placement fixture 2 includes a base plate 21, on which a set of support components 22 are provided. The set of support components 22 are spaced apart along the X direction. The support components 22 include a first support platform 221 and a second support platform 222. The upper surfaces of the first support platform 221 and the second support platform 222 respectively abut against the connecting terminals in the Z direction. The base plate 21 of the material placement fixture 2 serves as a basic load-bearing component, providing a stable platform for the entire support structure. A set of support components 22 spaced apart along the X direction are distributed on it. The upper surfaces of the first support platform 221 and the second support platform 222 respectively abut against the connecting terminals in the Z direction, accurately supporting the connecting terminals from multiple points. This effectively prevents the terminals from shaking or shifting during placement, transportation, and spraying, ensuring that the cold spraying operation can accurately act on the predetermined surface of the terminals and avoiding spraying deviations or defective products caused by terminal displacement. There are 4 sets of support components 22. The support components 22 are spaced apart along the X direction on the base plate 21. Each base plate 21 has 2 sets of support components 22, which are arranged in the Y direction.

[0033] In this embodiment, both the first support platform 221 and the second support platform 222 are provided with positioning protrusions 23. The positioning protrusions 23 are used to limit the connecting terminal on the support assembly 22 in the X and Y directions. The positioning protrusions 23 on the first support platform 221 and the second support platform 222 limit the connecting terminal in the X and Y directions, and work together with the bearing surface of the support platform itself to form a precise two-dimensional constraint system for the connecting terminal. When the connecting terminal is placed on the support assembly 22, the positioning protrusions 23 can quickly lock the corresponding edge or preset positioning part of the terminal, ensuring that the position of the terminal on the horizontal plane is fixed and preventing its translation and rotation in the X and Y directions, thus providing a guarantee for subsequent precise spraying. The first support platform 221 is provided with two positioning protrusions 23, and the second support platform 222 is provided with one positioning protrusion 23. The end of the connecting terminal placed on the second support platform 222 is provided with a positioning hole corresponding to the positioning protrusion 23.

The pressure plate 24 has a set of spray nozzles 240, and each set of spray nozzles 240 corresponds to a set of terminals to be sprayed. The pressure plate 24 is detachably mounted on the set of first support platforms 221, forming an upper and lower clamping structure with the support platform below, further stabilizing the terminals and ensuring that each terminal is accurately maintained in the preset spraying position. The set of spray nozzles 240 on the pressure plate 24 corresponds to a set of terminals to be sprayed, exposing only the parts that need coating, avoiding accidental spraying of cold spray paint onto other areas of the terminals that do not need treatment. This saves paint consumption and prevents excess paint from accumulating on the terminal surface, affecting electrical performance or subsequent assembly, and improves the precision of the spraying process. The material handling fixture 2 is provided with a pair of mounting columns, which are spaced apart in the X direction. The first support platform 221 is disposed between the pair of mounting columns, and the pressure plate 24 is detachably mounted on the pair of mounting columns.

[0035] like Figure 5 As shown, in this embodiment, the material conveying assembly 3 includes: a track 31, a slider 32, and a driving device 33.

The track 31 connects the spraying station and the material changing station, providing a precise and stable guide path for the movement of the slider 32. The slider 32, slidably mounted on the track 31, can slide smoothly along a predetermined route. With the cooperation of the driving device 33 in adjusting the sliding of the slider 32, the slider 32 with the base plate 21 mounted can be accurately conveyed to the designated station. There are two material conveying assemblies 3, spaced apart in the X direction.

[0036] This embodiment also includes a protective cover 6, which is installed over the material changing station. A linear drive device 61 is installed inside the protective cover 6. The fixed end of the linear drive device 61 is mounted on the inner wall of the protective cover 6, and the telescopic end of the linear drive device 61 is connected to a movable baffle 4. The protective cover 6, installed over the material changing station, forms a relatively independent enclosed area, effectively isolating the material changing operation from the external environment. On the one hand, it prevents dust, impurities, and other foreign objects from entering the material changing station, avoiding contamination of the wiring terminals to be sprayed and ensuring the cleanliness of the processed materials. On the other hand, it also prevents small amounts of debris and particles that may be generated during the material changing process from spreading to other areas of the workshop, maintaining the cleanliness of the entire production environment. Figure 3As shown, a set of sliding components 62 is provided at the sliding connection between the protective cover 6 and the movable baffle 4. The set of sliding components 62 are spaced apart in the X direction. The sliding component 62 includes: a guide rail 621 and a clamping block 622. The clamping block 622 is slidably mounted on the guide rail 621. The guide rail 621 and the clamping block 622 are respectively mounted on the movable baffle 4 and the protective cover 6.

[0037] In this embodiment, the dust collection assembly 5 includes: an upper-opening trough 51, a set of connecting pipes 52, and a dust collection box 53. The trough 51 is disposed at the spraying station, and the set of connecting pipes 52 is used to connect the trough 51 and the dust collection box 53.

The bottom is provided with a through hole 510 corresponding to the spraying port 240. When the material handling fixture 2 is located at the spraying station, the two are axially connected. When the terminal is sprayed through the through hole 510 and the spraying port 240, the residual paint will be collected in the container 51 and enter the dust collection box 53 through a set of connecting pipes 52. This prevents dust from spreading around the spraying station, keeps the entire work area clean and tidy, creates a good working environment for operators, and reduces the respiratory hazards of dust to operators.
