Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating technology, specifically to a drying device for electrophoretic processing. Background Technology

[0002] During electrophoretic processing, a large amount of water stains remain on the surface of the workpiece after electrophoresis. If these water stains are not removed in time, they will not only affect the appearance quality of the workpiece, causing defects such as watermarks and spots, but may also adversely affect subsequent processing steps, reducing the product yield. Furthermore, prolonged water stain residue can also cause corrosion on the workpiece surface, shortening its service life.

[0003] Traditional electrophoretic coating drying methods mainly involve natural air drying or simple air drying. Natural air drying is extremely inefficient, requiring a long time to completely dry water stains on the workpiece surface, which greatly affects production efficiency and cannot meet the needs of large-scale industrial production. While simple air drying improves the drying speed to some extent, its uncontrollable airflow pressure and temperature make it difficult to ensure that water stains are effectively removed from all parts of the workpiece, especially for some complex-shaped workpieces, where water stains in crevices and other areas are often difficult to remove completely.

[0004] Therefore, the market urgently needs a drying device that can efficiently and thoroughly remove water stains from the surface of workpieces after electrophoresis. Utility Model Content

[0005] In view of this, the present invention provides a drying device for electrophoretic processing. The workpiece can be moved during the drying process by the workpiece moving component, which avoids incomplete drying in some areas. Moreover, the workpiece can be dried from different directions by two sets of high-pressure airflow components, which improves the efficiency and effect of drying.

[0006] To solve the above-mentioned technical problems, this utility model provides a drying device for electrophoresis processing, including a fixed base, a fixed bracket installed on the fixed base, and a cleaning mechanism for removing water stains from the workpiece on the fixed bracket. The cleaning mechanism consists of a high-pressure airflow assembly and a workpiece moving assembly. The high-pressure airflow assembly is set in two groups, and each group of high-pressure airflow assemblies includes a mounting frame. The mounting frame is slidably set between the fixed base and the fixed bracket through a lifting module, and each mounting frame is equipped with an air box. Several high-pressure air nozzles are connected to one side of each air box.

[0007] That is, the connecting column slides on the fixed bracket through the sliding part, which drives the workpiece suspended on the hook to move, so that the workpiece can be blown by high-pressure airflow at different positions. Then, two sets of high-pressure airflow components can be used to air dry the workpiece from different directions, which improves the efficiency and effect of air drying. In addition, the lifting module allows the high-pressure air nozzle to be adjusted according to the height of the workpiece, which enhances the adaptability of the equipment. Furthermore, the workpiece moving component can move the workpiece during the air drying process to avoid incomplete local air drying and ensure the overall air drying quality of the workpiece.

[0008] One of the high-pressure airflow components is connected to a heating module for heating air. The heating module includes a heating element installed on one side of the air box and a heat dissipation copper pipe surrounding the inside of the air box. The two ends of the heat dissipation copper pipe are connected to the output end and the input end of the heating element, respectively.

[0009] That is, by heating the air in a set of high-pressure airflow components through the heating module, the heated air can accelerate the evaporation of water stains on the surface of the workpiece, further improving the drying efficiency. When dealing with some workpieces with high drying requirements, heated air can better meet their drying needs.

[0010] The top of the fixed bracket is connected to four sets of air intake modules, each of which provides an air source for a bellows.

[0011] That is, each set of air intake modules provides an air source for a single air box, ensuring that each air box can obtain a stable and sufficient air volume, thereby enabling the high-pressure nozzle to continuously generate high-pressure airflow and improving the stability of the drying effect.

[0012] Each air intake module includes a high-pressure blower mounted on top of a fixed bracket and an air duct located behind the air box. The output end of the high-pressure blower is connected to an air collection port, and a corrugated air duct is connected between the air collection port and the air duct.

[0013] In other words, the corrugated duct has a certain degree of flexibility, which can adapt to the lifting and lowering movement of the mounting frame, ensuring a stable air supply during the movement of the mounting frame. The high-pressure blower can provide a powerful air source, so that the airflow blown out by the high-pressure nozzle has high pressure and speed, which enhances the ability to remove water stains.

[0014] The lifting module includes guide rails symmetrically arranged between the fixed base and the fixed bracket. Each guide rail has a screw rotatably installed inside it. A drive block is threadedly connected to the screw. The mounting bracket is fixedly installed on the top of the drive block. In addition, a geared motor for driving the screw to rotate is installed at the bottom of the guide rail.

[0015] In other words, the lifting module can precisely control the height of the high-pressure air nozzle, making it adaptable to workpieces of different heights and improving the versatility of the equipment. Then, the screw is driven by a geared motor to achieve smooth and accurate lifting movements, ensuring the positional accuracy of the high-pressure air nozzle.

[0016] The workpiece moving assembly includes a connecting column that is slidably mounted on a fixed bracket via a sliding member, and a number of hooks for suspending the workpiece are connected to the connecting column.

[0017] That is, by using a workpiece moving component, the workpiece can be moved during the air drying process, avoiding the high-pressure airflow acting only on the fixed part of the workpiece, so that all parts of the workpiece can be dried evenly, thus improving the air drying quality.

[0018] The sliding component includes a slide groove set on the top of the fixed bracket, a lead screw rotatably installed inside the slide groove, a slider connected to the lead screw by threads, and a flange connected to the bottom of the slider. The bottom of the flange has a threaded through hole that matches the thread on the top of the connecting column.

[0019] That is, the movement of the workpiece can be flexibly controlled by the sliding parts, making it easy to adjust the position of the workpiece during the drying process. The use of threaded connection makes the installation and disassembly of the connecting column more convenient, facilitating the replacement of different workpiece suspension devices or the maintenance of the equipment.

[0020] The slider includes a drive motor for driving the lead screw to rotate.

[0021] That is, by driving the lead screw to rotate through the drive motor, the movement of the workpiece can be flexibly controlled, making it easy to adjust the position of the workpiece during the drying process.

[0022] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0023] 1. A cleaning mechanism consisting of a high-pressure airflow assembly and a workpiece moving assembly removes water stains from the electrophoretic workpiece. Each air box in the high-pressure airflow assembly is connected to several high-pressure nozzles on one side, generating a high-pressure airflow to dry the workpiece and quickly remove water stains from its surface. Simultaneously, the workpiece moving assembly allows the workpiece to move, ensuring that different parts of the workpiece are fully exposed to the high-pressure airflow, further improving the effectiveness and efficiency of water stain removal.

[0024] 2. The high-pressure airflow assembly is slidably mounted between the fixed base and the fixed bracket via a lifting module. The lifting module includes a guide rail, a screw, a drive block, and a geared motor. The geared motor drives the screw to rotate, causing the drive block to move on the screw, thereby raising and lowering the mounting frame and the air box. This allows for flexible adjustment of the distance between the high-pressure air nozzle and the workpiece according to its size and actual drying requirements, achieving the best drying effect.

[0025] 3. One set of high-pressure airflow components is connected to a heating module, including a heating element and a heat dissipation copper pipe surrounding the inside of the air box. The heat generated by the heating element is transferred to the air inside the air box through the heat dissipation copper pipe, turning the blown airflow into hot air. This allows for the selection of hot or cold air for drying depending on the material and process requirements of the workpiece, increasing the equipment's applicability and flexibility.

[0026] 4. The top of the fixed bracket is connected to four sets of air intake modules, each dedicated to providing airflow for one air box. Each air intake module includes a high-pressure blower, air duct, air inlet, and corrugated air duct. The air generated by the high-pressure blower is delivered to the air box through the air inlet and corrugated air duct, ensuring a stable and sufficient airflow for each air box. This guarantees that the airflow from the high-pressure nozzle has sufficient pressure and flow, thereby improving the drying effect. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0033] like Figures 1-4 As shown: This embodiment provides a drying device for electrophoresis processing. On the electrophoresis production line, a fixed base 1 is stably placed on the ground, and a fixed bracket 2 is installed on the fixed base 1. A cleaning mechanism 3 is used to remove water stains from the workpiece. The high-pressure airflow assembly 31 is configured in two sets, and the mounting frame 311 can slide between the fixed base 1 and the fixed bracket 2 via a lifting module 312. An air box 3125 is installed on the mounting frame 311, and several high-pressure air nozzles 3126 are connected to one side of the air box 3125. The workpiece moving assembly 32 can move the workpiece to a suitable position to receive the action of the high-pressure airflow.

[0034] Once the workpiece enters the working area of ​​the drying equipment, the lifting module 312 moves the mounting frame 311 up and down, adjusting the height of the high-pressure air nozzle 3126 to align it with the workpiece. High-pressure airflow is generated inside the air box 3125 and sprayed onto the workpiece surface through the high-pressure air nozzle 3126. The impact force of the high-pressure airflow blows away water stains from the workpiece surface, achieving the purpose of removing water stains.

[0035] like Figure 4 As shown: In a set of high-pressure airflow assemblies 31, a heating element 3131 is installed on one side of a blower box 3125, and a heat dissipation copper pipe 3132 is arranged around the inside of the blower box 3125, with both ends of the heat dissipation copper pipe 3132 connected to the output end and the input end of the heating element 3131, respectively. For example, when hot air drying of a workpiece is required, this set of high-pressure airflow assemblies 31 with heating module 313 is activated.

[0036] The heating element 3131 operates, converting electrical energy into heat energy. The heat transfer medium (such as hot air or heat transfer oil) is heated in the heating element 3131 and then circulates within the air box 3125 through the heat dissipation copper pipe 3132. The air inside the air box 3125 comes into contact with the heat dissipation copper pipe 3132, absorbing heat and thus raising the air temperature inside the air box 3125. When the high-pressure airflow passes through the air box 3125, the heated air is sprayed onto the workpiece surface through the high-pressure nozzle 3126. This not only blows away water stains but also accelerates moisture evaporation through the hot air, improving the drying effect.

[0037] like Figure 1 and Figure 3As shown: Four sets of air-expelling modules 314 are installed on the top of the fixed bracket 2, and each set of air-expelling modules 314 corresponds to one air box 3125. In actual production, when both sets of high-pressure airflow components 31 and their air boxes 3125 require an air source, the four sets of air-expelling modules 314 work simultaneously to provide sufficient air volume for the air boxes 3125.

[0038] The air intake module 314 provides airflow to the air box 3125. By equipping each air box 3125 with an air intake module 314, it can be ensured that each air box 3125 receives a stable and sufficient airflow, ensuring that the high-pressure nozzle 3126 can spray airflow with sufficient pressure and flow, thereby effectively removing water stains from the workpiece.

[0039] like Figure 1 and Figure 3 As shown: High-pressure blower 3141 is mounted on top of fixed bracket 2, and air duct is located behind air box 3125. The output end of high-pressure blower 3141 is connected to air collector 3142, and air collector 3142 is connected to air duct via corrugated air duct 3143. When the equipment is running, high-pressure blower 3141 starts to operate, drawing in and pressurizing outside air.

[0040] The high-pressure blower 3141 operates, drawing in and pressurizing outside air. The pressurized air is collected through the air inlet 3142, then transported through the corrugated duct 3143 into the ductwork, and finally enters the air box 3125. The corrugated duct 3143 has a certain degree of flexibility, which can adapt to the lifting and lowering movement of the mounting frame 311, ensuring the stability of the air source delivery.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown: Guide rails 3121 are symmetrically arranged between the fixed base 1 and the fixed bracket 2. A screw 3122 is rotatably mounted inside the guide rails 3121. A drive block 3123 is connected to the screw 3122 via threads. A mounting bracket 311 is fixed to the top of the drive block 3123. A reduction motor 3124 is mounted at the bottom of the guide rails 3121. When the height of the high-pressure nozzle 3126 needs to be adjusted, the reduction motor 3124 is activated.

[0042] The screw 3122 is driven to rotate by the geared motor 3124. Since the drive block 3123 is threadedly connected to the screw 3122, the rotation of the screw 3122 causes the drive block 3123 to move linearly along the screw 3122 within the guide rail 3121. The movement of the drive block 3123 drives the mounting frame 311 to move up and down, thereby adjusting the height of the high-pressure nozzle 3126 to accommodate workpieces of different sizes and positions.

[0043] like Figure 1 and Figure 2As shown: a slide groove 3211 is mounted on top of the fixed bracket 2, a lead screw 3212 is rotatably mounted inside the slide groove 3211, a slider 3213 is threaded to the lead screw 3212, a flange 322 is connected to the bottom of the slider 3213, and the flange 322 is threaded to the top of the connecting column 323. Several hooks 324 are connected to the connecting column 323 for suspending the workpiece. After electrophoresis processing, the workpiece is suspended on the hooks 324.

[0044] When the lead screw 3212 rotates, the slider 3213 moves linearly along the lead screw 3212. The movement of the slider 3213 causes the connecting column 323 to slide along the fixed bracket 2. The workpiece suspended on the hook 324 moves together with the connecting column 323, so that the workpiece can be accurately moved to the working area of ​​the high-pressure air nozzle 3126 to receive high-pressure airflow drying treatment.

[0045] like Figure 2 As shown: When installing the connecting post 323, align the thread on the top of the connecting post 323 with the threaded through hole on the bottom of the flange 322, and then rotate the connecting post 323 to make it tightly connected to the flange 322. When it is necessary to replace or maintain the connecting post 323, simply rotate the connecting post 323 in the reverse direction to remove it.

[0046] When the lead screw 3212 rotates, it drives the slider 3213 to slide within the groove 3211. The flange 322 at the bottom of the slider 3213 moves accordingly. Since the connecting column 323 is threadedly connected to the flange 322, the connecting column 323 moves together with the slider 3213. In this way, the workpiece can move on the fixed support 2, facilitating the drying of the workpiece by high-pressure airflow. Simultaneously, the threaded connection facilitates the installation and removal of the connecting column 323, making equipment maintenance and adjustment easier.

[0047] like Figure 1 and Figure 2 As shown: The sliding member 321 includes a drive motor 3214 for driving the lead screw 3212 to rotate. By driving the lead screw 3212 to rotate through the drive motor 3214, the movement of the workpiece can be flexibly controlled, making it easier to adjust the position of the workpiece during the drying process.

[0048] The method of using this utility model is as follows: The four sets of air-guiding modules 314 on the top of the fixed bracket 2 are activated sequentially. The high-pressure blower 3141 in each set of air-guiding modules 314 starts working, drawing in outside air. The air enters the corrugated duct 3143 through the air inlet 3142, and is then transported to the corresponding air box 3125 through the duct. The connecting column 323 is then moved by controlling the sliding member 321, activating the drive motor 3214 that drives the lead screw 3212. The rotation of the lead screw 3212 causes the slider 3213 to move along the lead screw 3212 within the groove 3211. Since the flange 322 at the bottom of the slider 3213 is threadedly connected to the top of the connecting column 323, the connecting column 323 moves to the appropriate position along with the slider 3213. The workpiece that needs to be air-dried after electrophoresis is then suspended on the hook 324 on the connecting column 323.

[0049] Then, based on the height of the workpiece, the lifting module 312 is activated to adjust the position of the high-pressure airflow assembly 31. The reduction motor 3124 at the bottom of the guide rail 3121 is turned on, and the reduction motor 3124 drives the screw 3122 to rotate. Since the drive block 3123 is connected to the screw 3122 by a thread, the rotation of the screw 3122 will cause the drive block 3123 to move up and down in the guide rail 3121, thereby driving the mounting frame 311 and the bellows 3125 to move up and down, adjusting the bellows 3125 to a suitable height position with the workpiece.

[0050] Then, select the air-drying mode according to the processing requirements:

[0051] Room temperature air drying: If the workpiece does not require heating and air drying, only the set of high-pressure airflow components 31 that is not connected to the heating module 313 can be used. The high-pressure air in the air box 3125 is ejected through several high-pressure air nozzles 3126 connected to one side of the air box 3125. The high-speed airflow acts on the surface of the workpiece, blowing off the water stains on the surface of the workpiece.

[0052] Heating and Drying: If heating and drying of the workpiece is required, the high-pressure airflow assembly 31 connected to the heating module 313 is activated. The heating element 3131 starts working, transferring heat to the heat dissipation copper pipe 3132 surrounding the air box 3125. The heat dissipation copper pipe 3132 dissipates the heat into the air inside the air box 3125, heating the air. The heated air is then ejected through the high-pressure nozzle 3126, which not only blows off water stains on the surface of the workpiece but also accelerates the evaporation rate of moisture, improving drying efficiency.

[0053] During the air-drying process, the sliding component 321 can be activated again, causing the connecting column 323 to slowly move the workpiece on the fixed support 2. This ensures that all parts of the workpiece are evenly exposed to the high-pressure air, guaranteeing consistent air-drying results.

[0054] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0055] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
