DETAILED DESCRIPTION

[0046] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0047] like Figures 1 to 5As shown, a bowl-shaped plug pressing device for new energy vehicle workpieces of the present invention includes: a machine platform 100, a conveying mechanism 200, a spraying mechanism 300, a bowl-shaped plug conveying mechanism 400, a pressing mechanism 500, a conveyor belt 600 and a fixing mechanism 700.

[0048] Specifically, the machine platform 100 is provided with a first station 110 and a second station 120, and the first station 110 and the second station 120 are arranged on the machine platform 100 at an interval; the conveying mechanism 200 has a first conveying member 210 movably arranged above the machine platform 100, and the first conveying member 210 is used to lift and convey the workpiece 800; the spraying mechanism 300 has a manipulator 310 connected to the machine platform 100 and a spraying member 320 connected to the operating end of the manipulator 310, the manipulator 310 drives the spraying member 320 to move above the machine platform 100, and the spraying member 320 is used to spray the workpiece 800; the bowl-shaped plug conveying mechanism 400 has a second conveying member 210 connected to the spraying member 320 The conveyor 410, the second conveyor 410 is used for grabbing and conveying the bowl-shaped plug; the pressing mechanism 500 has a first pressing rod 510 movably arranged on the first station 110, a second pressing rod 520 vertically arranged on the second station 120, and a third pressing rod 530 spaced around the second station 120; the first pressing rod 510, the second pressing rod 520 and the third pressing rod 530 are all used for the pressing operation of the bowl-shaped plug; the conveyor belt 600 is connected to the machine 100, and is used to receive and convey the assembled workpiece 800; the fixing mechanism 700, the first station 110, the second station 120 and the first conveyor 210 are all provided with the fixing mechanism 700, and is used to fix the workpiece 800.

[0049] When placing the workpiece 800 on the first station 110, manual handling or mechanical equipment can be used. When manual handling is selected, a positioning device can be set on the first station 110 to accurately position the workpiece 800, thereby facilitating subsequent operations. After the workpiece 800 is properly placed, the conveying mechanism 200 clamps the workpiece 800 using the fixing mechanism 700 equipped therewith, and then lifts and moves the workpiece 800 to the first glue spraying position, so that the first hole 810 of the workpiece 800 is exposed for glue spraying. During or after the glue spraying of the first hole 810 is completed, the bowl-shaped plug conveying mechanism 400 will deliver the bowl-shaped plug to be pressed to the first pressing rod 510, the second pressing rod 520 and the third pressing rod 530. Once the glue spraying process of the first hole 810 is completed, the conveying mechanism 200 will reset the workpiece 800, and the fixing mechanism 700 will firmly fix the workpiece 800 on the first station 110. Next, the first pressing rod 510 on the pressing mechanism 500 starts working to press the bowl-shaped plug into the first hole 810. Subsequently, the fixing mechanism 700 releases the workpiece 800, and the conveying mechanism 200 starts again to lift the workpiece 800 and transfer it to the second glue spraying position. At this time, the workpiece 800 is located above the second station 120. After the workpiece 800 reaches the second glue spraying position, the spraying device drives the nozzle through the robot arm to spray glue on the second hole 820 of the workpiece 800 again. After completing the glue spraying of the second hole 820, the conveying mechanism 200 delivers the workpiece 800 to the second station 120, and the fixing mechanism 700 of the second station 120 fixes the workpiece 800. After the workpiece 800 is fixed, the pressing mechanism 500 starts the third pressing rod 530 to press the bowl-shaped plug into the second hole 820. Afterwards, the conveying mechanism 200 clamps the workpiece 800 again through the fixing mechanism 700 thereon, and moves it to the third glue spraying position, and the third hole position 830 is subjected to glue spraying by the spraying device. Here, the third glue spraying position may be the same as the second glue spraying position, or it may be different. After completing the glue spraying of the third hole position 830, the conveying mechanism 200 sends the workpiece 800 back to the second station 120 and fixes it through the fixing mechanism 700, and then the pressing mechanism 500 presses the bowl-shaped plug into the third hole position 830 through the second pressing rod 520. Finally, the conveying mechanism 200 sends the workpiece 800 that has been pressed to the conveyor belt 600, and sends the workpiece 800 out through the conveyor belt 600, thereby completing the entire bowl-shaped plug pressing process of the workpiece 800.

[0050] Preferably, the bowl-shaped plug pressing device of the present scheme is also equipped with a code scanning device. When the workpiece 800 is placed on the first workstation 110, the fixing mechanism 700 fixes the workpiece 800 on the first workstation 110, and then the QR code on the workpiece 800 is scanned by the code scanning device to facilitate the subsequent tracking of the production process of the workpiece 800.

[0051] This solution completes the glue spraying operation of the workpiece 800 in sequence by moving the conveying mechanism 200 between the first station 110, the second station 120, the first glue spraying point, the second glue spraying point and the third glue spraying point, and completes the pressing of the bowl-shaped plugs in the first hole 810, the third hole 830 and the second hole 820 respectively by setting the first pressing rod 510, the second pressing rod 520 and the third pressing rod 530, effectively avoiding the problem of glue overflow caused by the long interval between glue spraying and pressing, thereby ensuring the quality of the pressing of the workpiece 800.

[0052] Furthermore, the second transport member 410 includes: a plurality of first brackets 411 connected to the spraying member 320; an adsorption rod 412, which is hollow and connected to the first bracket 411, one end of the adsorption rod 412 is connected to a suction cup 413, and the other end is used to connect to an air source; a spring 414, which is sleeved on the adsorption rod 412, and a limiting portion 415 is provided on the adsorption rod 412, one end of the spring 414 is pressed against the limiting portion 415, and the other end is pressed against the first bracket 411.

[0053] When working, one end of the adsorption rod 412 is connected to the air source, and negative pressure is formed in the adsorption rod 412, generating adsorption force, so that the bowl-shaped plug can be adsorbed on the suction cup 413. The suction cup 413 provides a buffering effect when it contacts the bowl-shaped plug, preventing the bowl-shaped plug from falling off from the press-fitting device due to excessive impact force at the moment of contact. When the manipulator 310 drives the adsorption rod 412 to move close to the bowl-shaped plug, the adsorption rod 412 first blows air to the bowl-shaped plug through the suction cup 413 to remove dust and impurities on the bowl-shaped plug to ensure the quality of press-fitting. The blowing time is 5 to 10 seconds.

[0054] Preferably, the bowl-shaped plug conveying mechanism 400 further comprises a vibration plate and a feeding track. The vibration plate is responsible for conveying the bowl-shaped plug to be assembled into the feeding track. When the bowl-shaped plug reaches the end of the track, the manipulator 310 drives the second conveying member 410 to move and take out the bowl-shaped plug.

[0055] The conveying mechanism 200 includes a first driving member 220 arranged above the machine 100 in a horizontal direction, and a second driving member 230 arranged in a vertical direction. The second driving member 230 is connected to the output end of the first driving member 220. The first conveying member 210 has a fixed platform 211 connected to the output end of the second driving member 230, and the fixing mechanism 700 is connected to the fixed platform 211.

[0056] The first driving member 220 and the second driving member 230 are preferably linear guides, which drive the fixed table 211 to move in the horizontal and vertical directions of the machine platform 100 through the action of the linear guides to complete the movement of the workpiece 800. The fixing mechanism 700 fixed on the fixed table 211 is used to realize the clamping of the workpiece 800 by the conveying mechanism 200.

[0057] The first pressure rod 510, the second pressure rod 520 and the third pressure rod 530 all have a gas channel arranged inside and a suction port 540 arranged at the end. When the gas channel is connected to the gas source, the suction port 540 suctions the bowl-shaped plug and blows air to the bowl-shaped plug.

[0058] The gas channels provided in the first pressure rod 510, the second pressure rod 520 and the third pressure rod 530 are used to absorb the bowl-shaped plug transported by the second transport member 410, and after the bowl-shaped plug is installed, the gas channels will blow air to the bowl-shaped plug to remove metal debris generated during the pressing process, wherein the blowing time for the bowl-shaped plug is 5 to 10 seconds.

[0059] The first pressing rod 510 , the second pressing rod 520 and the third pressing rod 530 are all sleeved with sealing rings 550 at their ends facing the workpiece 800 . When the suction port 540 sucks the bowl-shaped plug, the sealing ring 550 can be elastically deformed under the pressure of the bowl-shaped plug.

[0060] When the second conveying member 410 puts the bowl-shaped plug on the outside of the first pressure rod 510, the second pressure rod 520 and the third pressure rod 530, the bowl-shaped plug squeezes the sealing ring 550 to cause it to produce elastic deformation, thereby separating the bowl-shaped plug from the second conveying member 410. After the bowl-shaped plug is pressed into place, under the action of the first hole 810, the second hole 820 and the third hole 830, the bowl-shaped plug is separated from the first pressure rod 510, the second pressure rod 520 and the third pressure rod 530, and the sealing ring 550 returns to its initial state to receive the next bowl-shaped plug.

[0061] Preferably, the pressing mechanism 500 also includes a cylinder arranged on the machine platform 100 and corresponding to the first pressing rod 510, the second pressing rod 520 and the third pressing rod 530 one by one, and the cylinder is used to realize the movement of the first pressing rod 510, the second pressing rod 520 and the third pressing rod 530 on the machine platform.

[0062] The fixing mechanism 700 includes a third driving member 710, a pressing rod 720 connected to the output end of the third driving member 710, and a sensor 730 connected to the third driving member 710. The third driving member 710 is used to drive the pressing rod 720 to rotate, and the sensing end of the sensor 730 is facing the pressing rod 720.

[0063] The third driving member 710 is preferably a cylinder. When working, the third driving member 710 drives the pressing rod 720 to rotate and press on the workpiece 800 to complete the fixation of the workpiece 800. The sensor 730 is used to sense whether the pressing rod 720 has rotated to a preset position, thereby ensuring the pressing quality of the workpiece 800.

[0064] The present solution also provides a bowl-shaped plug press-fitting method for a new energy vehicle workpiece 800, comprising the steps of: S1, placing the workpiece 800 on a first workstation 110;

[0065] S2, lifting the workpiece 800 to the first glue spraying position;

[0066] S3, automatically spraying glue on the first hole 810 of the workpiece 800 that needs to be press-fitted with a bowl-shaped plug and is obliquely arranged inside the workpiece 800;

[0067] S4, resetting the workpiece 800 and fixing it;

[0068] S5, pressing the bowl-shaped plug into the first hole 810;

[0069] S6, releasing the fixation of the workpiece 800, lifting it and moving it to the second glue spraying position;

[0070] S7, automatically spraying glue on the second hole 820 on the outside of the workpiece 800 where the bowl-shaped plug needs to be pressed;

[0071] S8, fixing the workpiece 800 at the second workstation 120, and pressing the bowl-shaped plug into the second hole 820;

[0072] S9, releasing the fixation of the workpiece 800 and lifting it to the third glue spraying position;

[0073] S10, automatically spraying glue on the third hole 830 vertically arranged inside the workpiece 800 and requiring press-fitting of the bowl-shaped plug;

[0074] S11, resetting the workpiece 800 to the second station 120 and fixing it;

[0075] S12, press the bowl-shaped plug into the third hole 830.

[0076] Further preferably, the steps include: S101, fixing the workpiece 800 on the first workstation 110; S102, scanning the workpiece 800; S103, detecting whether there are bowl-shaped plugs on the first hole position 810, the second hole position 820 and the third hole position 830.
