[0037] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0038] The present invention is described in detail below in conjunction with the accompanying drawings.

[0039] Example 1

[0040] This embodiment discloses a post-curing device for spray-painted plastic parts of new energy vehicles, such as Figure 1 As shown, it includes a box body 1, both ends of the box body 1 are open, a controller 4 is installed on the side wall of the box body 1, and a lifting mechanism 2 is installed in the box body 1. The lifting mechanism 2 is composed of a motor 201, a transverse groove 202, and a tooth plate 203; specifically, the motor 201 is fixedly installed on the top plate of the box body 1 by bolts, the output shaft 205 of the motor 201 passes through the top plate of the box body 1 and is rotatably connected to the top plate of the box body 1, and the end of the output shaft 205 is fixedly connected with a gear 206. When the motor 201 is working, the output shaft 205 drives the gear 206 to rotate. It can be understood that the controller 4 adopts the existing technology, and the controller 4 is connected to the motor 201 to control the forward and reverse rotation of the motor 201 and the start and shut down and other actions; the controller 4 has a curing operation key and a curing completion key. After pressing the curing operation key, the painted plastic parts are hung for drying; after pressing the curing completion key, the cured plastic parts are taken out of the curing device.

[0041] like Figure 1 As shown, a transverse groove 202 is provided on the upper part of the two side walls of the box body 1, and a limit rod 207 is slidably connected in the transverse groove 202. One end of the limit rod 207 is welded and fixed on the tooth groove plate 203. When the tooth groove plate 203 moves, it drives the limit rod 207 to move; when the tooth groove plate 203 drives the limit rod 207 to move in one direction and moves to the end of the transverse groove 202, it is used to limit the tooth groove plate 203 from continuing to move and prevent it from moving out of the box body; it can be understood that the thickness of the tooth groove plate 203 is greater than the transverse groove 202.

[0042] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, multiple hooks 204 are evenly fixedly arranged at the bottom of the toothed plate 203 for hanging painted plastic parts; one side of the toothed plate 203 has a toothed groove, and the toothed groove specifications of the toothed plate 203 are consistent with the toothed groove specifications on the gear 206, and the width between the two toothed plates 203 is equal to the diameter of the gear 206, and the gear 206 is meshed with the toothed groove between the toothed plates; when the control motor 201 is working, the gear 206 drives the two toothed plates 203 to move in opposite directions, and then stops moving under the action of their respective limit rods 207. The other side of the toothed plate 203 is smooth, and the limit rod 207 is fixedly connected in the middle.

[0043] like Figure 1As shown, at both ends of the transverse groove 202, on the outer side of the side wall of the box body 1, a displacement sensor 209 is respectively provided, and the two displacement sensors 209 are used to detect the distance between the limit rod 207 and the displacement sensor 209, so as to determine whether the limit rod 207 is located at the two ends of the transverse groove or in the middle of the transverse groove. The displacement sensors 209 are connected to the controller 4, and the controller 4 can receive the displacement information transmitted by the displacement sensors 209. The selection of two displacement sensors 209 can increase the accuracy of detecting the position information of the limit rod 207.

[0044] In this embodiment, the controller 4 controls the forward and reverse rotation and the closing action of the motor 201 by obtaining the displacement information of the limit rod 207 detected by the two displacement sensors 209. Specifically, when the motor 201 rotates, it drives the limit rod 207 to move. When the two displacement sensors 209 detect that the limit rod 207 has reached the edge of one end of the transverse groove 202, the controller 4 controls the motor 201 to stop rotating according to the received signal. At this time, the staff hangs the painted plastic parts on the hooks 204 that leak out of the box 1. In this case, the painted plastic parts can be hung at both ends of the box 1 at the same time, and when hanging, the two toothed plates 203 will not interfere with each other, which can increase the efficiency of hanging the painted plastic parts.

[0045] In this embodiment, if Figure 5 As shown, inside the side wall of the box body 1, a guide plate is fixedly arranged on the upper and lower sides of the transverse groove 202, respectively, an upper guide plate 101 and a lower guide plate 102, a guide groove is formed between the two guide plates, and two tooth groove plates 203 are respectively placed in the guide grooves of the two side walls so that the teeth of the two tooth groove plates 203 are arranged opposite to each other.

[0046] like Figure 5 As shown, the length of the upper guide plate 101 and the lower guide plate 102 is consistent with the length of the tooth plate 203, but the width is less than half of the width of the tooth plate. The guide groove formed between the upper guide plate 101 and the lower guide plate 102 limits the movement of the tooth plate to prevent deviation.

[0047] like Figure 6 As shown, a ventilation mechanism is provided on the lower guide plate and the toothed plate, and the ventilation mechanism includes a plurality of straight ventilation holes 103 evenly provided on the lower guide plate 102, and the straight ventilation holes 103 penetrate the upper and lower surfaces of the lower guide plate; and also includes a plurality of inverted L-shaped ventilation holes 208 evenly provided on the toothed plate 203, and the inverted L-shaped ventilation holes have one end opening downward and the other end opening on the side where the limit rod 207 is located. When the toothed plate 203 is inside the box body 1 and the left and right ends of the toothed plate 203 and the lower guide plate are aligned, all the inverted L-shaped ventilation holes 208 are butted with the straight ventilation holes 103; at this time, the exhaust gas in the box body 1 is discharged through the plurality of connected inverted L-shaped ventilation holes 208 and the straight ventilation holes 103 through the transverse groove 202.

[0048] like Figure 4 , Figure 5 , Figure 6 As shown, a spring pin 210 is arranged on the hook 204. When the painted plastic part is hung on the hook 204, the spring pin 210 is pressed down. When the painted plastic part is removed from the hook 204, the spring pin 210 is restored under the spring force. A first sensor 211 and a second sensor 212 are also included. The tooth plate 203 is divided into two parts with the limit rod 207 as the center line. The first sensor 211 is arranged inside the tooth plate 203 on one side of the limit rod 207, and the second sensor 212 is arranged inside the tooth plate 203 on the other side of the limit rod 207.

[0049] It should be noted that inside the tooth plate 203, a plurality of contacts are set on the circuit of the first sensor 211 or the second sensor 212, corresponding to all the spring pins on this side; each contact corresponds to the position of a spring pin, and when the spring pin is pressed down, the spring pin will contact the contact, and when all the spring pins 210 of the tooth plate 203 on the side of the first sensor 211 are pressed down, that is, all the hooks 204 of the tooth plate 203 on this side are hung with painted plastic parts, then all the contacts are touched; the first sensor 211 transmits the information to the controller 4 in real time. Similarly, when all the spring pins 210 of the tooth plate 203 on the side of the second sensor 212 are pressed down, that is, all the hooks 204 of the tooth plate 203 on this side are hung with painted plastic parts, then all the contacts are touched, and the second sensor 212 transmits the information to the controller 4 in real time.

[0050] The first sensor 211 and the second sensor 212 are both connected to the controller 4. When the first sensor 211 or the second sensor 212 sends a signal to the controller 4 that all the contact points are touched, that is, plastic parts are hung on all the hooks on this side, the controller 4 controls the action of the motor 201. It can be understood that when all the spring pins are bounced, the first sensor 211 or the second sensor 212 will transmit the information that there are no plastic parts on all the hooks 204 on this side to the controller, and the controller will also control the action of the motor 201.

[0051] It can be understood that, in the present embodiment, since the two tooth plates 203 are installed relative to each other, when the two tooth plates 203 move relative to each other out of the box body 1, the tooth plate 203 at the end that leaks out of the box body 1 has the same internal sensors, that is, all are the first sensors or all are the second sensors. In the present embodiment, during the curing operation, the motor 201 rotates forward first, and the end of the tooth plate 203 that extends out of the box body 1 is installed with the first sensor 211.

[0052] In this embodiment, after the curing operation key is pressed, the controller 4 will proceed to the next step only when all the hooks 204 that have leaked out of the box body 1 are hung with painted plastic parts, that is, when the first sensors 211 inside the two toothed plates 203 transmit signals to the controller 4. After the curing operation key is pressed, when the contacts of the two first sensors 211 are in contact with the spring pin, the controller 4 controls the motor 201 to reverse until the two displacement sensors 209 detect that the limit rod 207 has moved to the other end of the horizontal groove 202, and the controller 4 controls the motor 201 to stop rotating. At this time, the hooks 204 that are not hung with painted plastic parts all extend out of the box body 1. The staff hangs the painted plastic parts on the hooks 204 until all the hooks 204 are full of painted plastic parts. At this time, when the contacts of the two second sensors 212 are in contact with the spring pins, the controller 4 receives the signals from the two second sensors 212 and controls the motor 201 to rotate forward until the two displacement sensors 209 detect that the limit rod 207 moves to the middle position of the transverse groove 202, and then controls the motor 201 to stop rotating. At this time, the tooth plate 203 is inside the box body 1 and the tooth plate 203 is aligned with the left and right ends of the lower guide plate.

[0053] It is understandable that in this embodiment, after the curing is completed, the curing device needs to send the cured plastic parts out of the box 1, and the control process of sending the cured plastic parts out of the box 1 is opposite to the control process of sending the painted plastic parts into the box 1. Specifically, after pressing the curing completion key, the controller controls the motor 201 to reverse until the limit rod is located at the edge of one end of the transverse groove, the controller controls the motor 201 to stop rotating, the staff removes all the dried plastic parts extending out of the box 1, and all the spring pins 210 extending out of the box 1 pop up, the controller controls the motor 201 to rotate forward until the limit rod is located at the edge of the other end of the transverse groove, the controller controls the motor 201 to stop rotating, the staff continues to remove all the dried plastic parts extending out of the box 1, and then the controller controls the motor 201 to reverse until the limit rod is located in the middle of the transverse groove.

[0054] like Figure 1 , Figure 3As shown, a drying mechanism 5 is also installed on the box 1, and the drying mechanism 5 is composed of a fan unit 501, a temperature detection meter 502, a heating rod 503 and a frame 504. Specifically, a through slot 104 is provided at the lower part of the two side panels of the box 1, and a frame 504 is provided in the through slot 104. Multiple groups of heating rods 503 are evenly arranged in the frame 504, and there are gaps between the heating rods 503. On the outside of the box 1, a fan unit 501 is provided on the outside of the frame 504. The fan unit 501 includes a fan cover and multiple fans. The multiple fans are fixed on the fan cover. By setting the fan cover outside the frame 504 and fixing it with bolts, the fan unit 501 is fixed to the outside of the side wall of the box 1. A temperature detection meter 502 is provided on the top wall of the box 1, and the temperature probe of the temperature detection meter 502 extends into the inside of the box 1 to detect the temperature inside the box 1. The controller 4 is connected to the temperature detection meter 502 and is used to receive the temperature signal transmitted by the temperature detection meter 502. The controller 4 is also connected to the fan and the heating rod 503 and can control the actions of the fan and the heating rod 503.

[0055] like Figure 1 As shown, both ends of the box body 1 are also movably provided with sealing plates 6 that can be opened and closed. Specifically, one end of the sealing plate 6 is connected to the box body 1 through a hinge. When in use, the two ends of the box body 1 can be sealed by the sealing plate 6. It should be noted that a third sensor 213 is provided between the other end of the sealing plate 6 and the box body 1. When the sealing plate 6 closes both sides of the box body 1, the sealing plate 6 contacts the end of the side wall of the box body 1, and the third sensor 213 transmits a signal to the controller 4, and the controller 4 controls the fan to start and controls the heating rod 503 to work at the same time. The temperature detection meter 502 transmits the real-time detected temperature inside the box 1 to the controller 4. The controller 4 controls the heat dissipation temperature of the heating rod 503 based on the real-time detected temperature information. When the temperature inside the box 1 reaches the set temperature, the controller 4 controls the heating rod 503 to stop working. After the heating rod 503 stops, the fan continues to rotate to dissipate heat. When the temperature detection meter detects that the box temperature drops to a safe temperature, the controller 4 controls the fan to stop working. Then the staff opens the sealing plate 6 and presses the curing completion button. The controller controls the motor to work and send the cured plastic parts out of the box.

[0056] like Figure 1 As shown, universal pulleys 3 are installed at the four corners of the bottom of the box 1. When in use, the box 1 is pushed and the universal pulleys 3 are used to move the box 1, so that the cured plastic parts can be transported to the next process position and then taken out. In some embodiments, the curing device is powered by a battery, and the battery can be installed at the bottom of the box 1 using a thermal insulation material.

[0057] It can be understood that the first sensor, the second sensor, and the third sensor can all be contact sensors in the prior art; the difference is that the first sensor and the second sensor have multiple contact points.

[0058] The required signals are obtained through the displacement sensor, the first sensor, the second sensor, the third sensor, and the temperature detection meter, and the signals are transmitted to the controller. The controller controls the action of the motor or the fan or the heating rod according to various signals, so that the curing device can achieve a certain degree of automation and improve efficiency.

[0059] Example 2

[0060] The present embodiment provides a control method for a post-painting curing device for a new energy vehicle plastic part, which uses a post-painting curing device for a new energy vehicle plastic part disclosed in Example 1, specifically:

[0061] Open the sealing plates 6 on both sides of the box body 1, and then press the curing operation key of the controller 4; the controller 4 first controls the motor 201 to rotate forward until the two displacement sensors 209 detect that the limit rod 207 moves to one end edge of the transverse groove 202, and the controller 4 controls the motor 201 to stop rotating according to the signals of the two displacement sensors 209, at this time, the painted plastic parts are hung on the hook at one end of the toothed plate extending out of the box body 1;

[0062] When all the hooks at one end of the toothed plate extending out of the box body 1 are hung with painted plastic parts, the two first sensors 211 transmit signals to the controller in real time, and the controller 4 controls the motor 201 to reverse until the two displacement sensors 209 detect that the limit rod 207 moves to the other end edge of the horizontal groove 202, and the controller 4 controls the motor 201 to stop rotating, at which time the painted plastic parts are hung on the hooks at the other end of the toothed plate extending out of the box body 1;

[0063] When all the hooks at the other end of the toothed plate extending out of the box body 1 are hung with painted plastic parts, the two second sensors 212 transmit signals to the controller in real time, and the controller 4 controls the motor 201 to rotate forward until the two displacement sensors 209 detect that the limit rod 207 moves to the middle of the horizontal groove 202, and the controller 4 controls the motor 201 to stop rotating;

[0064] Next, the staff seals the sealing plates 6 on both sides of the box 1, and the two third sensors 213 transmit signals to the controller 4, and the controller 4 controls the fan and the heating rod to work;

[0065] During the drying process, the temperature detection meter 502 transmits the box temperature to the controller 4 in real time, and the controller 4 controls the heating efficiency of the heating rod; until the temperature detection meter 502 detects that the box temperature reaches the set value, the controller 4 controls the heating rod to stop working;

[0066] After the heating rod 503 stops, the fan continues to rotate to dissipate heat. When the temperature detector detects that the box temperature has dropped to a safe temperature, the controller 4 controls the fan to stop working. Then the staff opens the sealing plate 6 and presses the curing completion button. The controller controls the motor to work and send the cured plastic parts out of the box.

[0067] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
