[0029] 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.

[0030] like Figures 1 to 5 As shown, a grid-type workpiece automatic coating device includes a machine 11, a machine cover 12, a loading line 21, a unloading line 22, a rotary worktable 30, a conveying mechanism 40, a driving mechanism 50 and a coating mechanism 60. The loading line 21, the unloading line 22 and the rotary worktable 30 are all arranged on the machine 11, and the rotary worktable 30 is located between the loading line 21 and the unloading line 22. The conveying mechanism 40 is slidably arranged on the machine 11 and is connected to the driving mechanism 50. The conveying mechanism 40 includes a pair of conveying units arranged front and back and with a fixed spacing, specifically including a first conveying unit 40a at the front end and a second conveying unit 40b at the rear end. The spacing between the first conveying unit 40a and the second conveying unit 40b is fixed and can move synchronously. The first conveying unit 40a is driven by the driving mechanism 50 to The workpiece 100 is moved to the rotary worktable 30 for processing (coating), and the second conveying unit 40b is driven by the driving mechanism 50 to move the processed (coated) grid-type workpiece 100 on the rotary worktable 30 to the unloading line 22; the first conveying unit 40a and the second conveying unit 40b have the same structure, both of which include a frame plate 41, a lifting cylinder 42, a lifting plate 43 and a removal assembly 44. The frame plate 41 can be horizontally slidably arranged on the slide rail of the machine 11 through a slider 401. The lifting cylinder 42 is arranged on the frame plate 41, and a lifting plate 43 is provided at the output end. The removal assembly 44 is arranged on the lifting plate 43 for abutting the two side walls and / or bottom end surface of the grid-type workpiece 100. The coating mechanism 60 is arranged on the second conveying unit 40b for coating the grid-type workpiece 100 on the rotary worktable 30.

[0031] Combine Figure 7As shown, during the production process, the upper end surfaces of the transverse ribs 101 and the longitudinal ribs 102 of the grid-type workpiece 100 need to be coated with the required coating for subsequent processing. Depending on the material and purpose of the grid-type workpiece 100, its upper end surface is coated with different substances, such as epoxy glue for bonding other products, or spray coating for passivation protection, etc. The specific coating process is as follows: multiple grid-type workpieces 100 are fed on the loading line 21, and when they reach the end of the loading line 21, they are blocked by the loading line 21, and the first conveying unit 40a is driven to move to the end of the loading line 21 (at the same time, the second conveying unit 40b moves to the top of the rotary worktable 30), and the first conveying unit 40a moves to remove one at the end of the loading line 21. Grid-type workpiece (at the same time, the second conveying unit 40b moves to remove the coated grid-type workpiece on the rotary worktable 30), after the driving mechanism 50 drives the first conveying unit 40a and the second conveying unit 40b to move along the feeding direction, the first conveying unit 40a is located above the rotary worktable 30, and the second conveying unit 40b is located above the starting end of the unloading line 22, and after the action, the grid-type workpiece to be coated is placed on the rotary worktable 30, and the coated grid-type workpiece is placed at the starting end of the unloading line 22, and the loading of the grid-type workpiece to be coated and the unloading of the coated grid-type workpiece are completed synchronously; after the first conveying unit 40a and the second conveying unit 40b are reset, the next group of grid-type workpieces can be fed. The coating of the grid-type workpiece is completed by the coordinated action of the rotating worktable 30, the transport unit, the driving mechanism 50 and the coating mechanism 60 (the transport unit does not perform the removal action during the coating process, but only performs the translation action). The rotating worktable 30 includes a rotating table 31 and a driving module 32 for driving the rotating table 31 to rotate in the horizontal plane. The coating mechanism 60 includes a translation module 61, a lifting module 62 and a coating head 63. The translation module 61 is arranged on the second transport unit 40b, the lifting module 62 is arranged at the output end of the translation module 61, and the coating head 63 is arranged on the lifting module 62 and is connected to the feeding system. The specific coating process is: first, the horizontal rib 101 is set to be coated. The coating is carried out, and the lifting module 62 drives the coating head 63 to move down to the position where it can act on the transverse rib 101, and coats it after feeding. Under the drive of the translation module 61, the coating action of the entire transverse rib 101 is completed. The driving mechanism 50 drives the second conveying unit 40b and the coating mechanism 60 located on the second conveying unit 40b to translate to the next transverse rib to complete the coating action. The same action completes the coating of all transverse ribs 101. The driving module 32 drives the rotating table 31 to rotate 90° in the horizontal plane. The same action completes the coating of all longitudinal ribs 102. After the second conveying unit 40b is reset, the grid-type workpiece coated on the rotary table 30 can be moved to the unloading line 22.

[0032] In the present invention, a pair of conveying units with fixed spacing are set up to synchronously complete the loading of the grid-type workpiece to be coated and the unloading of the coated grid-type workpiece, which can improve the feeding efficiency. The coating mechanism is integrated into the conveying unit at the rear end, and the coating of the grid-type workpiece is completed through the coordinated action of the two and the rotating worktable, which fully utilizes the mobility of the conveying unit at the rear end and has a more streamlined structure.

[0033] In order to ensure the smooth removal of the grid-type workpiece 100 and avoid it being affected by the loading line 21, the unloading line 22 or the rotating table 31 when its thickness is small, a first clearance groove 210 is set on the opposite sides of the end of the loading line 21, a second clearance groove 220 is set on the opposite sides of the starting end of the unloading line 22, and a third clearance groove 310 is set at the four sides of the rotating table 31, so that the end of the removal component 44 can be extended into and abut against the side wall and / or bottom end face of the grid-type workpiece 100; the removal component 44 includes a clamping cylinder 441 and a removal plate 442, the clamping cylinder 441 is arranged on the lifting plate 43, and a pair of removal plates 442 are arranged at the output end of the clamping cylinder 441 for abutting against the two sides and / or the bottom end face of the grid-type workpiece 100, that is, the end of the removal plate 442 can be extended into the clearance groove and abut against the grid-type workpiece 100.

[0034] Combine Figure 6 As shown, further, the removal plate 442 includes a clamping plate 4421 and a support plate 4422 arranged at the lower end of the clamping plate 4421. In one embodiment, when the clamping plate 4421 is driven by the clamping cylinder 441 to abut against the side wall of the grid-type workpiece 100, the support plate 4422 abuts against the bottom end surface of the grid-type workpiece 100. The bearing effect of the support plate 4422 can ensure the stability of the material transfer of the grid-type workpiece.

[0035] In another embodiment, based on the fact that the removing plate 442 has a clamping plate 4421 and a supporting plate 4422, the removing action of the removing plate 442 may not be performed by the clamping plate 4421 abutting against the side wall of the grid-type workpiece 100 for clamping, but only by the supporting plate 4422 abutting against the bottom end surface of the grid-type workpiece 100 and then driving the lifting cylinder 42 to lift the grid-type workpiece 100, which can avoid the clamping action of the clamping plate 4421 squeezing the side wall of the grid-type workpiece to cause deformation and other damage.

[0036] Continue as Figure 5 and 6As shown, based on the above-mentioned another embodiment in which the grid-type workpiece is moved only by the load-bearing and lifting action of the support plate 4422, the conveying mechanism 40 also includes a pressing component 45, which includes a horizontal plate 451, a vertical plate 452, a guide column 454 and a spring 455. The lower end of the lifting plate 43 is provided with a connecting column 453, and the guide column 454 is arranged at the lower end of the connecting column 453. The horizontal plate 451 can be moved up and down on the guide column 454 through the guide hole 4510 on its main body. The spring 455 is sleeved on the guide column 454, and the upper and lower ends are respectively abutted against the connecting column 453 and the horizontal plate 451. A pair of vertical plates 452 are arranged on the opposite sides of the horizontal plate 451 and are located between a pair of removing plates 442 for pressing down the grid-type workpiece 100. The support plate 4422 is pressed down by the pressing component 45 to stabilize the grid-type workpiece 100. The specific action process is as follows: the lifting cylinder 42 drives the lifting plate 43 to drive the removal component 44 and the pressing component 45 to move downward. During the downward movement, the clamping cylinder 441 drives the removal plate 442 to be in an open state, and the lower end face of the vertical plate 452 abuts against the upper end face of the grid-type workpiece 100. Due to the elastic action of the spring 455, the vertical plate 452 forms an elastic floating abutment with the grid-type workpiece 100, which can ensure that the grid-type workpiece 100 is not damaged. Then the clamping cylinder 441 drives the clamping plate 4421 and the support plate 4422 to move horizontally until the support plate 4422 extends into the lower end of the grid-type workpiece 100 through the clearance groove and achieves abutment. The stability of the grid-type workpiece 100 is guaranteed by the support plate 4422 and the floating downward pressure of the vertical plate 452.

[0037] Furthermore, a limiting column 403 for limiting the lifting plate 43 is provided on the frame plate 41 , which prevents the vertical plate 452 and the spring 455 from exerting excessive downward pressure on the grid-type workpiece 100 by limiting the bottom position of the lifting plate 43 .

[0038] Guide rail pairs 431 are respectively provided on both side walls of the frame plate 41 , and both ends of the lifting plate 43 are arranged on the guide rail pairs 431 , which can ensure the accuracy and stability of the movement of the lifting plate 43 .

[0039] In addition, a fixed connecting plate 404 is provided between the two frame plates of the first transport unit 40 a and the second transport unit 40 b to ensure the stability and synchronization of the entire transport mechanism 40 .

[0040] For the synchronous movement of the first transport unit 40a and the second transport unit 40b, the driving mechanism 50 includes a driving motor 51 and a transmission assembly 52 connected to the driving motor 51. The transmission assembly 52 may include a driving wheel, a driven wheel and a transmission belt. The driving wheel is arranged at the output end of the driving motor 51, and the driven wheel is arranged on the machine 11. The transmission belt is sleeved on the driving wheel and the driven wheel. The frame plate 41 is connected to the transmission belt through the connecting block 402, so as to realize accurate and smooth movement of the two transport units.

[0041] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
