[0034] Combination Figure 1-Figure 3The embodiment of the present invention provides an automatic workpiece varnishing device, comprising: a conveying mechanism 2, a photoelectric sensing mechanism 3, a pick-and-place mechanism 8, a workpiece positioning plate 9, a varnishing pool 10 and a control module 6. The conveying mechanism 2 is used to convey a workpiece 4, one side of which is connected to the discharge port of a feeding vibration plate 1; a workpiece positioning plate 9 is provided on the other side; the photoelectric sensing mechanism 3 is installed at the end of the conveying mechanism 2 and connected to the control module 6, and is used to sense the position information of the workpiece 4 on the conveying mechanism 2 and transmit the position information to the control module 6; the control module 6 is also connected to the pick-and-place mechanism 8, and is used to control the pick-and-place mechanism 8 to grab the workpiece 4 according to the position information. Then the workpiece 4 is placed in the workpiece positioning disk 9; a telescopic mechanism 5 is installed on the side of the workpiece positioning disk 9 close to the conveying mechanism 2, and the telescopic mechanism 5 is used to push the workpiece positioning disk 9 to the top of the paint immersion pool 10; the paint immersion pool 10 is arranged on the side of the workpiece positioning disk 9 away from the telescopic mechanism 5, and the length and width of the paint immersion pool 10 are both greater than the length and width of the workpiece positioning disk 9; a first hydraulic cylinder 13 is installed below the paint immersion pool 10, and the first hydraulic cylinder 13 is connected to the control module 6, and the control module 6 can control the first hydraulic cylinder 13 to move in a direction perpendicular to the working surface of the paint immersion pool 10 to immerse or move away from the workpiece positioning disk 9.

[0035] In the embodiment of the present invention, the workpiece 4 sent out by the feeding vibration plate is transmitted to one end of the transmission mechanism 2 equipped with the photoelectric sensor mechanism 3 through the transmission mechanism 2. Specifically, the transport state of the workpiece moving track 12 on the transmission mechanism 2 is as follows: Figure 2 As shown, the photoelectric sensor mechanism 3 then transmits the position information of the workpiece 4 to the control module 6, and the control module 6 controls the pick-and-place mechanism 8 to grab the workpiece 4 and transport it to the workpiece positioning plate 9, and then controls the telescopic mechanism 5 through the control module 6 to push the workpiece positioning plate 9 to the top of the varnish immersion pool 10. At this time, the control module 6 controls the first hydraulic cylinder 13 to push the varnish immersion pool 10 to move upward, and completely immerse the workpiece positioning plate 9 in the varnish immersion pool 10 to achieve painting of the workpiece 4. When the painting is completed, the first hydraulic cylinder 13 drives the varnish immersion pool 10 away from the workpiece positioning plate 9. The automatic varnish immersion device for workpieces of this scheme realizes the painting of the workpiece 4 through automated machinery throughout the process, effectively solving the problem of low production efficiency and high cost caused by manually placing the workpiece 4 to the set position and then manually varnishing the workpiece 4, which cannot be automated. The automatic varnish immersion device of this scheme realizes a complete set of processes of automatic sorting, transportation and painting of the workpiece 4, improves production efficiency, reduces labor costs, and reduces the degree of harm of paint to the health of employees.

[0036] like Figure 1 and Figure 2 As shown, the pick-and-place mechanism 8 includes a pick-and-place assembly 84 , a first drive structure 83 , a second drive structure 82 and a third drive structure 81 ; the pick-and-place assembly 84 is disposed at the front end of the first drive structure 83 for picking up and placing the workpiece 4 .

[0037] The first driving structure 83 is connected to the control module 6 , and is used to drive the pick-and-place assembly 84 to approach or move away from the workpiece 4 after receiving a driving signal from the control module 6 .

[0038] Specifically, the first driving structure 83 includes a second hydraulic cylinder 831 and a sliding rod 832. The second hydraulic cylinder 831 is electrically connected to the control module 6. The rear end of the sliding rod 832 is fixedly connected to the piston rod of the second hydraulic cylinder 831, and the front end is connected to the pick-and-place assembly 84, so that the extension and retraction of the piston rod drives the pick-and-place assembly 84 to approach or move away from the workpiece 4.

[0039] When the first driving structure 83 is working, the control module 6 controls the piston rod of the second hydraulic cylinder 831 to extend or retract, driving the sliding rod 832 to rise or fall, and then driving the pick-and-place assembly 84 to approach or move away from the workpiece 4 to grasp the workpiece 4.

[0040] The first driving structure 83 is arranged on the second driving structure 82, and the second driving structure 82 extends in a direction perpendicular to the transmission mechanism 2. The second driving structure 82 is connected to the control module and can drive the first driving structure 83 to move along the extension direction of the second driving structure 82 after receiving the driving signal.

[0041] Specifically, the second driving structure 82 includes a second guide rail 822, a second screw 821 and a second motor 823; wherein the plane where the second screw 821 is located is located above the conveying mechanism 2, the second screw 821 is perpendicular to the extension direction of the conveying mechanism 2, a nut is sleeved on the second screw 821, the first driving structure 83 is fixedly connected to the nut, and the output shaft of the second motor 823 is connected to one end of the second screw 821.

[0042] As a further optimization of this solution, the second guide rail 822 is a groove-shaped guide rail, and the extension direction of the second guide rail 822 is parallel to the extension direction of the second screw rod 821. The second screw rod 821 is installed in the second guide rail 822, and the nut is also located in the second guide rail 822. The fixing position of the nut and the first driving structure 83 is located at the groove mouth of the second guide rail 822. Such a design can protect the rotation of the second screw rod 821 and prevent external factors from interfering with the movement of the second driving structure 82. At the same time, it also ensures the stability of the movement of the nut sleeved on the second screw rod 321, thereby ensuring the stability of the movement of the first driving structure 83, and can also play a certain guiding role in the movement of the first driving structure 83.

[0043] When the second drive structure 82 is working, the control module 6 controls the output shaft of the second motor 823 to rotate forward or reverse, which will drive the second screw 821 to rotate forward or reverse. The nut sleeved on the second screw 821 can move back and forth on the second screw 821, thereby driving the first drive structure 83 to move back and forth on the second guide rail 822.

[0044] The third driving structure 81 includes two groups of third driving components, which are respectively arranged on both sides of the conveying mechanism 2, and the extension direction of the third driving components is parallel to the extension direction of the conveying mechanism 2; the two ends of the second driving structure 82 are respectively arranged on the two groups of third driving components; the third driving structure 81 is connected to the control module 6, and can drive the second driving structure 82 to move along the extension direction of the third driving structure 81 after receiving the driving signal.

[0045] The movement principle of the third driving structure 81 is the same as that of the second driving structure 82. Specifically, the third driving assembly includes a first motor 812, a first screw 813 and a third guide rail 811, wherein the first screw 813 is arranged parallel to the top of the conveying mechanism 2, and the extension direction of the first screw 813 is parallel to the extension direction of the conveying mechanism 2, a nut is sleeved on the first screw 813, the end of the second screw 821 is fixedly connected to the nut sleeved on the first screw 813, and the output shaft of the first motor 812 is fixedly connected to the end of the first screw 813.

[0046] As a further optimization of this solution, the third guide rail 811 is a groove-shaped guide rail, and the extension direction of the third guide rail 811 is parallel to the extension direction of the first screw rod 813. The first screw rod 813 is installed in the third guide rail 811, and the nut sleeved on the first screw rod 813 is also located in the third guide rail 811. The fixing position of the nut and the second screw rod 821 of the second drive structure 82 is located at the groove mouth of the third guide rail 811. Such a design can protect the rotation of the first screw rod 813 and prevent external factors from interfering with the movement of the third drive structure 81. At the same time, it also ensures the stability of the movement of the nut sleeved on the first screw rod 813, thereby ensuring the stability of the movement of the third drive structure 81, and can also play a certain guiding role in the movement of the third drive structure 81. In addition, in order to ensure the stability of the installation of the first screw rod 813 and the stability of the operation of the third drive structure 81, side plates 7 are arranged in parallel on both sides of the transmission mechanism 2, and the first screw rod 813 is fixed on the side plates 7.

[0047] When the third driving structure 81 is working, the control module 6 controls the output shaft of the first motor 812 to rotate forward or reverse, which will drive the first screw 813 to rotate forward or reverse. The nut sleeved on the first screw 813 moves back and forth on the first screw 813, thereby driving the second driving structure 82 to move on the second guide rail 822.

[0048] like Figure 1 As shown, the photoelectric sensing mechanism 3 includes a plurality of photoelectric sensors 31 arranged in a linear array on the side of the conveying mechanism 2; the plurality of photoelectric sensors 31 are all connected to the control module; the photoelectric sensors 31 can sense the position information of the workpiece 4 and transmit the position information to the control module.

[0049] A plurality of linear array photoelectric sensors 31 are arranged on the side of the conveying mechanism 2. When the workpiece 4 conveyed on the conveying mechanism 2 passes through the photoelectric sensor 31, the photoelectric sensor 31 will send a signal to the control module 6. When the position information of the workpiece 4 is sensed on the conveying mechanism 2 at all the photoelectric sensors 31, the control module 6 will control the pick-and-place mechanism 8 to grab and transport the workpiece 4. First, the control module 6 controls the first drive structure 83 to approach the workpiece 4 and controls the pick-and-place assembly 84 to grab the workpiece 4, and then controls the first drive structure 83 to move away from the conveying mechanism 2; then the control module 6 controls the third drive structure 81 to make the second drive structure 82 move along the extension direction of the first screw 813, and transport the grabbed workpiece 4 to the workpiece positioning disk 9; then the control module 6 controls the second drive structure 82 to make the first drive structure 83 move along the extension direction of the second screw 821, and move the first drive structure 83 and the pick-and-place assembly 84 together into the workpiece positioning disk 9; finally, the control module 6 controls the first drive structure 83 to move downward, and controls the pick-and-place assembly 84 to release the workpiece 4, thereby completing the automatic grabbing and transportation of the workpiece 4.

[0050] like Figure 1 and Figure 2 As shown, it also includes two first guide rails 14, which are respectively arranged in parallel on both sides of the workpiece positioning disk 9 and extend to the paint immersion pool 10; the two sides of the workpiece positioning disk 9 are respectively arranged on the two first rails and can slide along the first guide rails 14, and the outer wall of the workpiece positioning disk 9 is provided with a paint inlet hole.

[0051] In this solution, the workpiece positioning disk 9 is arranged between two parallel first guide rails 14, and the two sides of the workpiece positioning disk 9 are respectively installed on the first guide rails 14, and the workpiece positioning disk 9 is guided by the first guide rails 14, so as to avoid the workpiece positioning disk 9 from deviating in the process of moving to the paint immersion pool 10, and at the same time, it is also ensured that the process of the workpiece positioning disk 9 moving the workpiece 4 to the top of the paint immersion pool 10 is more stable. At the same time, in order to effectively immerse the workpiece 4 of the workpiece positioning disk 9 in the paint immersion pool 10, a paint inlet hole is opened on the outer wall of the workpiece positioning disk 9. Specifically, the paint inlet hole can be opened on the side wall of the workpiece positioning disk 9, or the paint inlet hole can be opened at the bottom of the workpiece positioning disk 9, or the paint inlet hole can be opened on the side wall and the bottom of the workpiece positioning disk 9, so as to facilitate painting of the workpiece 4, and after the painting is completed, when the paint immersion pool 10 is away from the workpiece positioning disk 9, the excess paint in the workpiece positioning disk 9 can flow back to the paint immersion pool 10 through the paint inlet hole.

[0052] like Figure 1 and Figure 2 As shown, the workpiece positioning plate 9 is provided with a plurality of evenly arranged workpiece placement grids 91 , and a workpiece 4 is placed in each workpiece placement grid.

[0053] The workpiece positioning disk 9 of the present solution is configured as a plurality of evenly arranged workpiece placement grids 91, and a workpiece 4 is placed in each workpiece placement grid 91. The number of workpiece placement grids 91 arranged in the workpiece positioning disk 9 along the extension direction of the first guide rail 14 is the same as the number of workpieces 4 grasped by the pick-and-place assembly 84 or is an integer multiple of the number of workpieces 4 grasped. Such a design facilitates the placement of the workpiece 4 by the pick-and-place mechanism 8 and improves work efficiency. In addition, placing a workpiece 4 in a separate workpiece placement grid 91 leaves enough space around each workpiece 4, which can ensure that the outer surface of each workpiece is evenly painted. At the same time, compared with directly placing the workpiece 4 on a plane, the present solution places the workpiece 4 in a separate workpiece placement grid 91, which also ensures the stability of the placement of the workpiece 4.

[0054] like Figure 2 As shown, the telescopic mechanism 5 includes a telescopic rod 51 , the telescopic direction of the telescopic rod 51 is consistent with the movement direction of the workpiece positioning plate 9 , and the telescopic rod 51 is fixedly connected to the workpiece positioning plate 9 .

[0055] The telescopic rod 51 is fixedly connected to the workpiece positioning plate 9, and the telescopic direction of the telescopic rod 51 is consistent with the movement direction of the workpiece positioning plate 9, that is, the telescopic rod 51 is parallel to the first guide rail 14. The control module 6 controls the telescopic rod 51 to extend, push the workpiece positioning plate 9 to move along the first guide rail 14, and when retracted, the telescopic rod 51 can directly pull the workpiece positioning plate 9 back along the first guide rail 14 to achieve automation.

[0056] like Figure 1 As shown, the pick-and-place assembly 84 is capable of picking up and placing a plurality of workpieces 4 at the same time.

[0057] In order to improve work efficiency, the effective grasping length of the pick-and-place component 84 is set to be the same as the length of the area of ​​the workpiece 4 that can be sensed by the photoelectric sensor mechanism 3, so that the pick-and-place component 84 can pick up and place multiple workpieces 4 at the same time during one transportation process.

[0058] like Figure 3 As shown, the pick-and-place assembly 84 includes two grippers 841 arranged in parallel; the pick-and-place assembly 84 is connected to the control module 6 , and the control module 6 can control the grippers 841 to grip and release the workpiece 4 .

[0059] The pick-and-place component 84 is designed as two parallel grippers 841, the length of the grippers 841 is the same as the length of the area of ​​the workpiece 4 that can be sensed by the photoelectric sensing mechanism 3, and the opening and closing states of the grippers 841 are controlled by the control module 6, that is, the grasping and releasing of the workpiece 4 is controlled, which greatly facilitates the pick-and-place component 84 to grasp workpieces 4 of different models.

[0060] refer to Figure 1 and Figure 2 , including multiple parallel transmission mechanisms 2. Multiple transmission mechanisms 2 are arranged in parallel, and multiple corresponding photoelectric sensor mechanisms 3 are also arranged accordingly, which speeds up the grasping and conveying speed of the workpiece 4 and improves the work efficiency.

[0061] As a further optimization of this embodiment, a stopper 11 is provided at the end of the conveying mechanism 2 in this scheme where the photoelectric sensor mechanism 3 is installed, which can effectively prevent the conveying mechanism 2 from continuously transmitting and transporting the workpiece 4 to the end of the conveying mechanism 2 and then falling, thereby effectively avoiding the workpiece 4 from falling.

[0062] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0063] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
