[0050] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.
[0051] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0052] Please see Figure 1 This disclosure provides a load beam leveling adjustment mechanism, including: a base 100; a drive assembly 200 correspondingly disposed on the base 100; a cam mounting bracket 300 disposed on each of the drive assemblies 200, and an eccentric cam follower 400 disposed on the cam mounting bracket 300; the eccentric cam follower 400 is respectively disposed at both ends of the beam 500; and the beam 500 is connected to a die head 540; the drive assembly 200 is adapted to drive the beam 500 to move the die head 540 up and down; when the beam 500 tilts during the lifting process, the tilting force of the beam 500 is adapted to drive the eccentric cam follower 400 to rotate, so as to eliminate the height error on both sides of the beam 500, thereby avoiding the tilting of the beam 500 and the die head 540 during the lifting process.
[0053] See Figure 4 In some embodiments, the eccentric cam follower 400 includes: a screw 420 with an oil nozzle 430 disposed therein; a nut 440 rotatably disposed on the screw 420; an outer ring 410 rotatably connected to the screw 420 and eccentric to the screw 420; and the outer ring 410 being connected to both ends of the crossbeam 500.
[0054] Specifically, lubricating oil can be added to the screw 420 through the grease nipple 430 to reduce the friction between the outer ring 410 and the screw 420, thereby increasing the service life of the eccentric cam follower 400.
[0055] Furthermore, the outer ring 410 of the eccentric cam follower 400 is eccentric to the screw 420 and the outer ring 410 is connected to both ends of the crossbeam 500. When the crossbeam 500 tilts during the lifting process, the tilting force of the crossbeam 500 is suitable for driving the outer ring 410 of the eccentric cam follower 400 to rotate around the screw 420 as the axis, so as to eliminate the height error on both sides of the crossbeam 500.
[0056] See Figure 3 , Figure 4 In some embodiments, the cam mounting bracket 300 has a mounting hole corresponding to the screw 420. The screw 420 passes through the mounting hole and the eccentric cam follower 400 is fastened to the cam mounting bracket 300 by tightening the nut 440.
[0057] See Figure 2 In some embodiments, the crossbeam 500 includes an upper crossbeam 510 and a lower crossbeam 520, the upper crossbeam 510 and the lower crossbeam 520 having through holes that match the outer ring 410, and the upper crossbeam 510 and the lower crossbeam 520 being fastened to the outer ring 410 by a locking member 700.
[0058] See also Figure 2 , Figure 4 In some embodiments, a balance cylinder 600 is provided on one side of the cam mounting bracket 300, and the weight of the balance cylinder 600 matches the weight of the crossbeam 500 and the die head 540.
[0059] Specifically, by setting balance cylinders 600 on the cam mounting brackets 300 on both sides of the crossbeam 500, the phenomenon of lateral tilting and instability is less likely to occur, which helps to improve the stability and safety of the entire adjustment mechanism.
[0060] See Figure 1 In some embodiments, the upper crossbeam 500 is further provided with arc-shaped chamfers 530 at both ends. This feature prevents the user from being scratched during use and further improves the safety of the adjustment mechanism.
[0061] See also Figure 1 The drive assembly 200 includes a servo motor 210, which is connected to a lead screw 230 via a coupling 220. The lead screw 230 is connected to a cam mounting bracket 300.
[0062] Specifically, the two ends of the crossbeam 500 are connected to the cam mounting bracket 300 through the eccentric cam follower 400 and the cam mounting bracket 300 through the lead screw 230. When the servo motor 210 is working, it can drive the two ends of the crossbeam 500 to move up and down through the lead screw 230.
[0063] Some embodiments also provide a coating machine including an adjustment mechanism for the level of the load beam as described in the above embodiments.
[0064] In summary, this load beam leveling adjustment mechanism, by setting an eccentric cam follower 400 on the drive assembly 200, connecting both ends of the beam 500 to the eccentric cam follower 400, and connecting the beam 500 to the die head 540, when the beam 500 tilts during the process of the drive assembly 200 driving the beam 500 to raise and lower the die head 540, the rotation of the eccentric cam follower 400 can eliminate the height error on both sides of the beam 500, thereby preventing the beam 500 and the die head 540 from tilting during the raising and lowering process.
