DETAILED DESCRIPTION

[0035] 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.

[0036] The present invention is described in detail below in conjunction with the accompanying drawings.

[0037] Example 1

[0038] This embodiment discloses a new energy vehicle plastic parts painting equipment, such as Figure 1 As shown, it includes a load platform 1 and an L-shaped plate 4, one side of the vertical plate of the L-shaped plate 4 is fixedly connected to one side of the table of the load platform 1, and the other side is fixedly provided with a controller 3, and a paint spraying mechanism 5 is also installed on the L-shaped plate; a fixing mechanism 2 is installed in the middle of the table of the load platform 1, and the plastic parts can be fixed by the fixing mechanism 2, and a measuring component 6 is also arranged on both sides of the table of the load platform 1, and the measuring component 6 includes two measuring plates 601 that can be raised and lowered, and the two measuring plates 601 are used to measure the length of the plastic parts between the two measuring plates 601. Four support columns are arranged under the table of the load platform 1.

[0039] Specifically, Figure 1 , Figure 2 As shown, the fixing mechanism 2 is composed of a vertical rod 201, a motor A202, a vacuum suction cup 203, a first gear 204, a second gear 205, a rotating shaft 206, and a synchronizer 207; wherein, the vertical rod 201 is rotatably connected to the table plate of the support platform 1 through a bearing, and the motor A202 is also fixedly installed on the table plate of the support platform 1, and the motor A202 can be rotated forward and reversed. In the present embodiment, the motor A202 is arranged on the side of the vertical rod 201 away from the L-shaped plate 4, and in some embodiments, it can also be arranged on other sides; a rotating shaft 206 is installed on the output end of the motor A202, and the rotating shaft 206 passes downward through the table plate of the support platform 1 and is rotatably connected to the table plate of the support platform 1, and the end of the rotating shaft 206 away from the motor A202 is connected to the synchronizer 207, and the rotating shaft 206 is also hollowly sleeved with a first gear 204. It should be noted that the first gear 204 is provided with a first spline toward the synchronizer 207 for connecting with the synchronizer 207. It can be understood that the rotating shaft 206 and the first gear 204 can be connected in an empty sleeve manner through a needle bearing, that is, the rotating shaft 206 and the first gear 204 rotate with each other without affecting each other; when the synchronizer 207 is connected to the first spline, the rotating shaft 206 is connected to the first gear and can rotate together.

[0040] like Figure 1 As shown, the top of the vertical rod 201 is connected to the vacuum suction cup 203, and the second gear 205 is fixedly set on the bottom outer wall of the vertical rod 201; the vertical rod 201 is a hollow tube, and the bottom inner wall of the vertical rod 201 is connected to the connecting pipe of the vacuum equipment through a sealed bearing (not shown in the figure); when the plastic part is placed on the vacuum suction cup 203, the vacuum equipment is started, and the vacuum equipment fixes the plastic part through the connecting pipe and the vertical rod.

[0041] In this embodiment, the motor A202 and the vacuum device are both connected to the controller 3; a signal sensor can be set in the vacuum device, and the signal sensor is used to transmit the vacuum device start signal to the controller 3. When the vacuum device is started, the controller 3 controls the motor A202 to start forward rotation.

[0042] In this embodiment, the first gear 204 is connected to the second gear 205 through a gear chain. When the first gear 204 rotates, the second gear 205 is driven to rotate, and the vertical rod 201 is driven to rotate, and finally the vacuum suction cup 203 is driven to rotate, thereby driving the plastic part to rotate. It can be understood that by connecting the synchronizer 207 to the first gear 204, the first gear 204 and the rotating shaft 206 are rotated together.

[0043] like Figure 1 , Figure 2 As shown, the paint spraying mechanism 5 is composed of a motor B501, a T-block 502, a first threaded rod 503, a first electric telescopic rod 504, a paint spraying head 505, and a transverse groove 506; wherein, a motor B501 is installed on the upper side of the mounting controller 3 of the L-shaped plate 4 by bolts, and the motor B501 can be rotated forward and reversely. The first threaded rod 503 is installed on the output end of the motor B501, and the first threaded rod 503 is rotatably connected to the vertical plate of the L-shaped plate 4; a transverse groove 506 is opened at the center of the horizontal plate of the L-shaped plate 4, and a T-block 502 is slidably set in the transverse groove 506, specifically, the vertical block of the T-block 502 passes through the transverse groove 506, and the transverse block is supported on the upper part of the transverse groove 506; a first threaded hole is opened horizontally on the vertical block of the T-block 502, which is used to be threadedly connected to the rod body of the first threaded rod 503. After the T-block 502 is threadedly connected to the first threaded rod 503, the first threaded rod 503 is parallel to the transverse plate of the L-shaped plate 4.

[0044] like Figure 1 , Figure 2 As shown, a first electric telescopic rod 504 is also installed at the bottom of the vertical block of the T-block 502, and the output end of the first electric telescopic rod 504 is movably connected to a paint spray head 505, the paint spray head 505 is replaceable, and the paint spray head 505 can be connected to a paint spraying device.

[0045] like Figure 1 , Figure 2 As shown, a first sensor 401 is fixedly arranged at the bottom of one end of the horizontal plate of the L-shaped plate 4 away from the vertical plate, and the first sensor 401 is used to detect the distance between the T-shaped block 502 and itself, so as to know the distance between the paint spray head 505 and itself. The motor B501, the first electric telescopic rod 504, the first sensor 401, and the paint spraying equipment are all connected to the controller 3.

[0046] It is understandable that the first sensor 401 transmits the detection signal to the controller 3, and the controller 3 knows the current position of the paint spray head 505 according to the detection signal of the first sensor 401; according to the size information of the plastic part, the controller 3 controls the motor B501 to rotate forward, so that the paint spray head 505 moves to the top of one end of the length direction of the current plastic part, and then the controller 3 controls the motor B501 to reverse until it reaches the top of the other end of the length direction of the current plastic part, and the controller 3 controls the motor B501 to rotate forward until it returns to the top of one end of the length direction of the current plastic part and stops rotating. It is understandable that according to the needs of painting, the paint spray head 505 can be required to reciprocate multiple times.

[0047] The controller 3 can also determine whether the height of the current paint spray head 505 is too high or too low according to the size of the plastic part, and then control the first electric telescopic rod 504 to drive the paint spray head 505 to move up and down. In some embodiments, the first electric telescopic rod 504 has two telescopic lengths, long and short. When the length of the plastic part is less than a certain value, the position of the paint spray head 505 needs to move downward by a certain distance, and the first electric telescopic rod 504 will reach the long telescopic length; and when the length of the plastic part is greater than a certain value, the position of the paint spray head 505 needs to move upward by a certain distance, and the first electric telescopic rod 504 will reach the short telescopic length. It can be understood that the specific value is actually set according to the actual size of the device and the size of the paint spray head, and the telescopic length of the first electric telescopic rod 504 can also be divided into three or more types; after the paint spray head 505 is connected to the paint spraying equipment, the controller 3 can control the paint spraying equipment to spray paint the plastic part through the paint spray head 505.

[0048] like Figure 1 , Figure 3 As shown, a measuring hole 101 is respectively provided at both ends of the table plate of the supporting platform 1, and the measuring hole 101 is slidably connected to the measuring plate 601; a second bolt hole is vertically opened inside the measuring plate 601, and a second threaded rod 602 is threadedly connected in the second bolt hole, and a first bevel gear 6021 is fixedly provided at the bottom end of the second threaded rod 602, and a smooth section is provided at the bottom of the second threaded rod 602, which is arranged in the first bracket 604 and is rotatably connected to the first bracket 604.

[0049] Specifically, the first brackets 604 are all L-shaped brackets, the horizontal ends of the L-shaped brackets are all rotatably connected to the smooth section of the second threaded rod 602, and the first bevel gear 6021 is located below the horizontal end of the L-shaped bracket; the first bevel gear 6021 is meshed with the second bevel gear 6061, and the second bevel gear 6061 is fixedly arranged at one end of the first round rod 606, and the other end of the first round rod 606 is fixedly arranged with the third bevel gear 6062; the end of the first round rod 606 with the second bevel gear 6061 is rotatably connected to the vertical end of the first bracket 604, and the end with the third bevel gear 6062 is rotatably connected to the second bracket 605. The difference is that the two first brackets 604 are arranged opposite to each other, and the lengths of the two first round rods 606 are different.

[0050] like Figure 1 , Figure 3 As shown, the second bracket 605 is an H-shaped bracket, including two vertical ends and one horizontal end; a first round rod 606 is rotatably set on both sides of the second bracket 605. It can be understood that in this embodiment, when one end of the two first round rods 606 with the third bevel gear 6062 is rotatably connected to the vertical end of the second bracket 605, the vertical end on the same side as the first round rod 606 is connected.

[0051] like Figure 1 , Figure 3 As shown, the second bracket 605 is rotatably connected to the second round rod 607 on the horizontal end, the fourth bevel gear 6071 is fixedly arranged at the bottom of the second round rod, and the second spline 6072 is fixedly arranged at the top, and the fourth bevel gear 6071 is meshed with the third bevel gear 6062. The second bracket 605 is also provided with a second electric telescopic rod 608, the output end of the second electric telescopic rod 608 is connected to a fork 6081, and the fork is connected to the synchronizer 207, and the synchronizer 207 is connected or disconnected with the second spline 6072 or the first spline by controlling the second electric telescopic rod 608 to drive the fork 6081.

[0052] It is understandable that the rotating shaft 206 and the second round rod 607 should be coaxially arranged to ensure that when the rotating shaft and the second round rod are connected by a synchronizer, they can rotate together; the synchronizer and the shift fork both adopt the existing technology, and the output end of the second electric telescopic rod 608 has three telescopic lengths: the shortest, medium, and longest. When the output end of the second electric telescopic rod 608 is at the shortest telescopic length, the synchronizer is connected to the second spline 6072, when the output end of the second electric telescopic rod 608 is at the longest telescopic length, the synchronizer is connected to the first spline, and when the output end of the second electric telescopic rod 608 is at the medium telescopic length, the synchronizer is not connected to the first spline or the second spline. It is also understandable that the two first brackets, the second bracket, and the four support columns are all fixedly connected to the ground, or the first bracket and the second bracket are connected to the four support columns through a connecting plate, the purpose of which is to ensure the transmission stability of the measuring component 6.

[0053] like Figure 1 , Figure 3 As shown, the second sensor 603 is embedded on the opposite side of the two measuring plates 601. When the two measuring plates 601 are raised at the same time, the second sensor 603 is driven to rise. When the second sensor 603 rises to the surface where the plastic part is located, the distance between the plastic part and itself will be known, while the distance between the two second sensors remains unchanged. Therefore, according to the measurement data of the two second sensors 603, the length of the plastic part can be obtained. It should be noted that the first sensor 401 and the second sensor 603 at its bottom are located in the same vertical interface; in addition, after measuring the plastic part, the second sensor 603 falls with the measuring plate. When the second sensor 603 falls into the table of the carrier 1, it stops falling. This is to protect the second sensor 603 from being contaminated during painting.

[0054] It can be understood that, since the fourth bevel gear 6071 is in the middle when it is meshed with the two third bevel gears, the two third bevel gears rotate in opposite directions, which causes the two second threaded rods to rotate in opposite directions. If the thread directions of the two second threaded rods are consistent, the two measuring plates 601 will move in opposite directions in the vertical direction. Therefore, the thread directions of the two second threaded rods are set in opposite directions to ensure that the two measuring plates 601 rise and fall at the same time in the vertical direction. In this embodiment, when the motor A rotates forward, the measuring plate rises, and when it rotates reversely, the measuring plate falls. In other embodiments, the opposite settings may also be used; the first sensor and the second sensor are both distance sensors (also called displacement sensors).

[0055] In this embodiment, the second sensor 603 and the second electric telescopic rod 608 are both connected to the controller 3. When the vacuum device is started, the controller 3 controls the motor A202 to rotate forward, and at the same time controls the output end of the second electric telescopic rod 608 to be at the shortest telescopic length, so that the synchronizer is connected to the second spline 6072, so that the motor A202 drives the second threaded rod 602 to rotate through the transmission of the fourth bevel gear, the third bevel gear, and the second bevel gear, and finally drives the second sensor 603 to rise and fall, and the length of the plastic part is measured. The second sensor 603 transmits the measurement result to the controller 3, and the controller 3 controls the motor B501 to rotate, so that the paint spray head 505 first moves to the end of the length direction of the plastic part close to the first sensor 401, that is, the end of the second sensor 603 close to the bottom of the first sensor 401 stops, and this end is recorded as the beginning of the length of the plastic part, and the other end is the end of the length.

[0056] Then the controller 3 controls the motor A to reverse, driving the second sensor 603 to fall until the second sensor 603 falls into the table of the supporting platform. The controller controls the output end of the second electric telescopic rod 608 to be at the longest telescopic length. At this time, the plastic part begins to rotate. At the same time, the controller 3 controls the paint spraying equipment to start and controls the motor B to rotate, so that the paint spraying head 505 moves in the direction away from the first sensor until the paint spraying head reaches the end of the length of the plastic part transmitted by the second sensor, and then controls the motor B to reverse. When the paint spraying head returns to the beginning of the length of the plastic part, the controller controls the motor B and the paint spraying equipment to stop, and at the same time controls the output end of the second electric telescopic rod 608 to be at a medium telescopic length. Finally, the motor A is controlled to stop rotating.

[0057] In some embodiments, an alarm may be added, which is connected to the controller 3. When the controller 3 just starts to control the motor A to rotate forward, a paint start signal is sent to the alarm to prompt the start of painting; when the controller 3 controls the motor A to stop, a paint end signal is sent to the alarm to prompt the end of painting.

[0058] Example 2

[0059] The working method of a new energy vehicle plastic part painting equipment disclosed in this embodiment uses a new energy vehicle plastic part painting equipment disclosed in Example 1. The working method is specifically as follows:

[0060] Place the long side of the plastic part on the vacuum suction cup 203 parallel to the direction of the transverse groove, make the center of the plastic part on the vacuum suction cup as much as possible, and then start the vacuum equipment to fix the plastic part;

[0061] After the vacuum equipment is started, the controller 3 controls the motor A202 to rotate forward, and at the same time controls the output end of the second electric telescopic rod 608 to be at the shortest telescopic length, so that the synchronizer 207 is connected with the second spline 6072, so that the motor A202 drives the second threaded rod 602 to rotate through the transmission of the fourth bevel gear, the third bevel gear, and the second bevel gear, and finally drives the second sensor 603 to rise and fall, so as to measure the length of the plastic part;

[0062] The two second sensors 603 transmit the measurement results to the controller 3, and determine whether the height of the current paint spray head 505 is too high or too low according to the measured size of the plastic part; if it is determined that the height of the paint spray head is high, the controller 3 controls the first electric telescopic rod 504 to move downward by a certain distance; if it is determined that the height of the paint spray head is low, the controller 3 controls the first electric telescopic rod 504 to move upward by a certain distance; if the height of the paint spray head does not need to be adjusted, the first electric telescopic rod 504 does not move;

[0063] Then the controller 3 controls the motor B501 to rotate, so that the paint spray head 505 first moves to one end of the length direction of the plastic part close to the first sensor 401, that is, stops at one end of the second sensor 603 close to the bottom of the first sensor 401. This end is recorded as the beginning of the length of the plastic part, and the other end is recorded as the end of the length.

[0064] Then the controller 3 controls the motor A202 to reverse, driving the second sensor 603 to fall, until the second sensor 603 falls into the table of the carrying platform 1; then the controller 3 controls the output end of the second electric telescopic rod 608 to be at the longest telescopic length, and the plastic part starts to rotate;

[0065] At the same time, the controller 3 controls the paint spraying equipment to start and controls the motor B501 to rotate, so that the paint spraying head 505 moves in a direction away from the first sensor 401 until the paint spraying head 505 reaches the end of the length of the plastic part transmitted by the second sensor 603, and then controls the motor B501 to reverse, so that the paint spraying head 505 returns to the beginning of the length of the plastic part;

[0066] The controller 3 controls the motor B501 and the paint spraying equipment to stop, and controls the output end of the second electric telescopic rod 608 to be at a medium telescopic length, and finally controls the motor A202 to stop rotating.

[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.
