Description

Technical Field

[0001] This utility model belongs to the technical field of coating equipment, and specifically relates to an automatic immersion coating device. Background Technology

[0002] Immersion coating is a coating method that involves immersing the workpiece in a coating solution and then lifting it out, so that the area of ​​the workpiece to be coated is evenly coated with the solution to form a protective film. Because the workpiece needs to be immersed, and the immersion depth varies depending on the different workpieces, there are partial immersion, semi-immersion, and full immersion. Currently, manual immersion is often used. However, manual immersion has many problems such as large errors in immersion depth and high labor intensity, resulting in low consistency of coated product quality, high production costs, and great difficulty in quality control. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automatic immersion coating device to replace manual immersion, thereby solving the technical problems of low product quality consistency, high production cost, and difficulty in quality control associated with manual immersion coating.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an automatic immersion coating device, including an immersion tank, a set of lifting feeding mechanism, a set of lowering storage mechanism, and a set of transfer mechanism. The lifting feeding mechanism and the lowering storage mechanism are respectively located upstream and downstream of the immersion tank. The transfer mechanism is located above the lifting feeding mechanism, the immersion tank, and the lowering storage mechanism. The lifting feeding mechanism is provided with a station for placing a carrier. The carrier is used to place the workpiece. The lifting feeding mechanism transports the carrier from bottom to top. The transfer mechanism reciprocates back and forth along the transport direction of the lifting feeding mechanism, the immersion tank, and the lowering storage mechanism. The transfer mechanism includes a translation module arranged along the arrangement path of the lifting feeding mechanism, the immersion tank, and the lowering storage mechanism, a lifting module connected to the translation module and moving synchronously, a bracket connected to the lower end of the lifting module, and several pneumatic grippers connected to the bracket for gripping the carrier. The lifting module drives the bracket to rise and fall, and the bracket drives the pneumatic grippers to fall to the position of the carrier to grip it.

[0005] As a preferred embodiment, the lifting feeding mechanism includes a pair of vertically arranged conveyor belts with opposite rotation directions and a driver that drives the two conveyor belts to rotate synchronously in opposite directions. The upper and lower ends of the conveyor belts are respectively wound on a conveyor roller. "L"-shaped support plates are symmetrically arranged on the two conveyor belts. A workstation for placing a carrier is formed between a pair of support plates on the vertical surfaces of the two conveyor belts facing each other. When the carrier is placed on the workstation, both sides of the carrier rest on the straight edges of the two support plates respectively. The lifting feeding mechanism conveys the carrier upward. The structure of the lowering storage mechanism is the same as that of the lifting feeding mechanism, but the conveying direction is opposite.

[0006] As a preferred embodiment, the two conveying rollers at the bottom of the lifting feeding mechanism are respectively connected to worm gears at the same end. A drive shaft perpendicular to the conveying rollers is arranged above the two worm gears. The drive shaft is provided with worms that correspond to the two worm gears one by one. The two ends of the drive shaft are supported by bearing seats. The driver is a motor, and one end of the drive shaft is connected to the motor for transmission.

[0007] As a preferred embodiment, the translation module is a linear motor, and the lifting module is a cylinder or a lead screw jack.

[0008] As a preferred embodiment, the lifting module is a high-speed cylinder.

[0009] As a preferred embodiment, a sensor for detecting the carrier is provided on one side of the lifting feeding mechanism. When the sensor detects the carrier, the corresponding carrier is precisely at the clamping position of the transfer mechanism to clamp the carrier.

[0010] The beneficial effects of this utility model are as follows: This utility model uses an upward feeding mechanism to transport a carrier, and a transfer mechanism to grab the carrier and move it above the immersion tank. After stopping, the carrier is lowered to allow the workpieces on the carrier to be immersed in the chemical solution. Then, the carrier is lifted and transferred to a lowering storage mechanism, which lowers and stores the carrier. The operator only needs to place the workpieces that have not been immersed in the chemical solution onto the carrier in sequence and insert the carrier into the workstation between the pairs of support plates on the upward feeding mechanism. Then, the carrier and workpieces that have been immersed in the chemical solution are removed from the lowering storage mechanism and transferred to the baking equipment for baking. The entire immersion process does not require manual operation. By adjusting the descent height of the lifting module when immersing the workpiece in the chemical solution, the workpiece can be stably immersed in the chemical solution to the same depth, thereby solving the technical problems of low product quality consistency, high production cost, and difficulty in quality control of manually immersed coating products.

[0015] The specific implementation scheme of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] like Figure 1 and Figure 2 An automatic immersion coating apparatus is shown, comprising an immersion tank 1, a lifting feeding mechanism 2, a lowering storage mechanism 3, and a transfer mechanism 4. The lifting feeding mechanism 2 and the lowering storage mechanism 3 are respectively located upstream and downstream of the immersion tank 1. The transfer mechanism 4 is located above the lifting feeding mechanism 2, the immersion tank 1, and the lowering storage mechanism 3. The lifting feeding mechanism 2 has a station for placing a carrier 5, which is used to place workpieces. The lifting feeding mechanism 2 transports the carrier 5 from bottom to top. The transfer mechanism 4 moves along the lifting feeding mechanism 2, the immersion tank 1, and the lowering storage mechanism 3. The material conveying mechanism 3 moves back and forth in the conveying direction. The transfer mechanism 4 includes a translation module 401 arranged along the arrangement path of the rising feeding mechanism 2, the impregnation tank 1, and the falling storage mechanism 3; a lifting module 402 connected to the translation module 401 and moving synchronously; a bracket 403 connected to the lower end of the lifting module 402; and several pneumatic grippers 404 connected to the bracket 403 for gripping the carrier 5. The lifting module 402 drives the bracket 403 to rise and fall, and the bracket 403 drives the pneumatic grippers 404 to fall to the position of the carrier 5 to grip the carrier 5.

[0017] In this embodiment, the carrier 5 is a wire mesh structure with a rectangular frame. When the workpiece is immersed in the medicine, the medicine can pass through the carrier 5 without obstruction.

[0018] The lifting feeding mechanism 2 described in this embodiment includes a pair of vertically arranged conveyor belts 201 with opposite rotation directions and a driver 202 that drives the two conveyor belts 201 to rotate synchronously in opposite directions. The upper and lower ends of the conveyor belts 201 are respectively wound on a conveyor roller 203. "L"-shaped support plates 204 are symmetrically arranged on the two conveyor belts 201. A workstation for placing the carrier 5 is formed between the pair of support plates 204 on the vertical surfaces of the two conveyor belts 201 facing each other. When the carrier 5 is placed on the workstation, the two sides of the carrier 5 rest on the straight edges of the two support plates 204 respectively. The lifting feeding mechanism 2 conveys the carrier 5 upward. The structure of the lowering storage mechanism 3 is the same as that of the lifting feeding mechanism 2, but the conveying direction is opposite.

[0019] As an improvement to the above technical solution, the two conveying rollers 203 at the lower part of the lifting feeding mechanism 2 are respectively connected to the same end of the two conveying rollers 203. A drive shaft 7 perpendicular to the conveying rollers 203 is set above the two worm wheels 6. The drive shaft 7 is provided with worms 8 that correspond to the two worm wheels 6 one by one. The two ends of the drive shaft 7 are supported by bearing seats 9. The driver 202 is a motor. One end of the drive shaft 7 is connected to the motor and drives the two worm wheels 6 to rotate synchronously through the worms 8, thereby ensuring that the two conveyor belts 201 of the lifting feeding mechanism 2 move synchronously in opposite directions. The structure of the lowering storage mechanism is also the same.

[0020] The translation module 401 is a linear motor, and the lifting module 402 is a cylinder or a lead screw jack. In this embodiment, a cylinder, especially a high-speed cylinder, is preferably used as the lifting module 402 to improve the lifting speed of the bracket 403 and the carrier 5. After the workpiece is immersed in the medicine, the lifting module 402 rises to lift the workpiece above the surface of the medicine. The workpiece can then be shaken by high-speed short-distance lifting to quickly shake off excess medicine from the workpiece, so that no medicine drips after the workpiece is transferred to the lowering storage mechanism 3.

[0021] like Figure 2 As shown, in this embodiment, a sensor 10 for detecting the carrier is provided on one side of the lifting feeding mechanism 2. When the sensor 10 detects the carrier 5, the corresponding position of the carrier 5 is exactly at the clamping station of the transfer mechanism 4. The specific position of the sensor 10 is adaptively set according to the shape characteristics of the carrier 5, with the aim of accurately detecting the carrier 5 that has arrived at the clamping station. This setting method is a conventional technical means in the art, so it will not be described in detail here.

[0022] In practical applications, sensor 10, lifting feeding mechanism 2, lowering storage mechanism 3, and transfer mechanism 4 are all connected to a controller and controlled by the controller. The controller determines whether there is a carrier 5 that needs to be clamped for soaking in medicine at the loading station based on the signal from sensor 10, and controls the lifting feeding mechanism 2 to work or pause, the lowering storage mechanism 3 to work or pause, and the transfer mechanism 4 to perform translation, lifting, clamping, and releasing actions.

[0023] In this embodiment, a sensor 10 for detecting the carrier 5 can also be preferably provided on one side of the lowering storage mechanism 3. The sensor is preferably positioned at the same height as the uppermost station of the lowering storage mechanism 3 to detect whether the carrier 5 is present at the uppermost station. The detection result is used by the controller to determine whether the carrier 5, which has been soaked in the medicine solution, can be placed at the uppermost station of the lowering storage mechanism 3. The structure of the sensor 10 on one side of the lowering storage mechanism 3 can refer to the structure of the sensor 10 on one side of the rising feeding mechanism 2. Of course, the user can also set more sensors 10 according to actual needs to detect whether the carrier 5 is present at more stations.

[0024] The working process of this utility model is as follows: Figure 1 and Figure 2 As shown, the automatic immersion coating device is first started. After startup, all components are initialized. The bracket 403 of the transfer mechanism 4 is moved to the top of the lifting feeding mechanism 2. The operator inserts multiple carriers 5 carrying workpieces into multiple stations of the lifting feeding mechanism 2 in sequence. The two ends of the carriers 5 extend out of the conveyor belt 201. The lifting feeding mechanism 2 is started, and it begins to transport all carriers 5 upwards. When the uppermost carrier 5 is detected by the sensor 10, the driver 202 of the lifting feeding mechanism 2 stops, the lifting module 402 of the transfer mechanism 4 is activated, and the drive bracket 403 is lowered, causing the pneumatic gripper 404 to descend to the gripping station. Then, the pneumatic gripper 404 is activated to grip the carrier 5. The lifting module 402 then rises and resets. After resetting, the translation module 401 transports the carrier 5 to the top of the immersion tank 1 and pauses. The lowering module 402 then drives the support 403 and carrier 5 to descend. The descent height is pre-set to ensure the workpiece is submerged in the liquid as required. The lifting module 402 then drives the support 403 and carrier 5 to rise, raising the workpiece above the liquid surface. The lifting module 402 is controlled to rapidly and shortly reciprocate to shake off excess liquid from the workpiece. After shaking, the lifting module 402 resets, and the translation module 401 continues to move towards the lowering storage mechanism 3 until it is directly above it. The lifting module 402 then drives the support 403 and carrier 5 to descend above the pair of support plates 204 at the top of the lowering storage mechanism 3, releasing the pneumatic grippers 404. The carrier 5 is then placed on the lowering storage mechanism 3, which activates and lowers the carrier 5 by one step. One step is the distance between two adjacent support plates 204 on the conveyor belt. Workers can remove and transfer the carrier 5 when it is full or nearly full on the lowering storage mechanism 3.

[0025] Sensors can also be installed on the lowering storage mechanism 3 as needed to detect the presence of the carrier 5. When the lowest carrier 5 reaches the lower limit position, it can be detected by the sensor, which can trigger an alarm to remind the operator to remove the carrier 5 on the lowering storage mechanism 3.

[0026] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
