[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] SeeFigures 1 to 7 , a headrest skeleton electroplating system, including a U-shaped electroplating tank 1, above which there is an annular conveying chain ( Figure 1 at A in the figure), and the running direction of the annular conveying chain corresponds to that of the U-shaped electroplating tank 1.

[0033] At the ends of the U-shaped electroplating tank 1, there are a loading device 2, a robotic arm 3, a jig frame 4 and a drying device 5. On the front side of the loading device 2, there are two fixed step plates 21, and on the outer sides of the two fixed step plates 21, there is one movable step plate 22 respectively. The left and right movable step plates 22 are both slidably connected to the base of the loading device 2, and the movable step plates 22 reciprocate up and down relative to the base of the loading device 2. On the front sides of the two fixed step plates 21, there are fixedly connected feeding guide plates 211, and on the rear sides of the two fixed step plates 21, there are fixedly connected discharging guide plates 212.

[0034] On the transverse two sides of the top wall of the loading device 2, there are support bars 23, and on the top walls of the support bars 23, there are multiple support grooves 231. At the end of the last joint arm body of the robotic arm 3, there is a fixedly connected mounting cross plate 31, and on the mounting cross plate 31, there are multiple clamping cylinders 32 fixedly connected. The clamping cylinders 32 are distributed in two upper and lower layers, and there is a gap between two adjacent clamping cylinders 32 in the same layer. The clamping cylinders 32 in the upper and lower layers are staggered horizontally with each other.

[0035] The jig frame 4 is provided with two cross bars 41, which are distributed up and down. On the front and rear sides of the two cross bars 41, there are multiple pairs of clamping forks. The upper clamping forks and the lower clamping forks are used to jointly clamp a raw material rod 6 of the headrest skeleton. The two cross bars 41 are connected with two vertical bars 42, and at the tops of the two vertical bars 42, there are hooks 421. The annular conveying chain ( Figure 1 at A in the figure) has multiple chain links connected with suspension rods (not shown in the figure), and the hooks 421 are used to hook the suspension rods.

[0036] Specifically, the support bar 23 is provided with ten support grooves 231. Correspondingly, the number of the clamping cylinders 32 in both the upper and lower layers is five. The clamping cylinders 32 in the upper layer and the clamping cylinders 32 in the lower layer are staggered horizontally with each other, and each clamping cylinder 32 is provided with two clamping claws.

[0037] Specifically, a pair of clamping forks belonging to the same group includes a straight bar 431 and a bent bar 432. The ends of the straight bar 431 and the bent bar 432 are both bent outward ( Figure 4 at B in the figure), and the bent bar 432 is provided with a bent section at a position close to the end, and the bent section protrudes outward.

[0038] Specifically, there are five pairs of clamping forks on the front and rear sides of the two cross bars 41.

[0039] Specifically, displacement bars 24 are slidably arranged on the inner sides of the two supporting bars 23. Two push cylinders 25 are arranged on the front and rear sides of the feeding device 2. The piston rods of the two push cylinders 25 are fixedly connected to the two ends of the displacement bar 24 respectively. A plurality of notches are arranged on the upper side of the displacement bar 24. The notches are provided with pushing inclined edges 241. The longitudinal distance of the pushing inclined edges 241 corresponds to the distance between two adjacent supporting grooves 231.

[0040] Specifically, the robotic arm 3 is arranged between the feeding device 2 and the drying device 5.

[0041] Specifically, the drying device 5 is provided with a conveyor belt 51 and an oven 52. The conveyor belt 51 passes through the oven 52.

[0042] Specifically, the headrest frame raw material rod 6 is in a long strip shape.

[0043] The working principle of the present utility model is as follows:

[0044] See Figure 1 , the U-shaped electroplating tank 1 is filled with electroplating solution. Above the U-shaped electroplating tank 1, there is an annular conveying chain (at A in Figure 1 ). The running direction of the annular conveying chain corresponds to the running direction of the U-shaped electroplating tank 1. Multiple links of the annular conveying chain (at A in Figure 1 ) are connected with suspension rods (not shown in the figure).

[0045] See Figure 5 , first, the feeding trolley (not shown in the figure) is loaded with a batch of stacked headrest frame raw material rods 6. The headrest frame raw material rods 6 are placed horizontally. The feeding trolley feeds multiple headrest frame raw material rods 6 onto the two feeding guide plates 211. The headrest frame raw material rods 6 roll backward along the feeding guide plates 211 to the edge of the fixed step plate 21. Subsequently, the movable step plates 22 on both sides move up and down reciprocally. Each time they move up, each step on the upper side edge thereof will lift multiple headrest frame raw material rods 6 at the corresponding height position upward, so that each headrest frame raw material rod 6 is gradually lifted along each step of the fixed step plate 21, and then reaches the discharging guide plate 212 one by one, and thus reaches each supporting groove 231 one by one.

[0046] Subsequently, the push cylinder 25 drives the displacement bar 24 to move up and down reciprocally. Each time the displacement bar 24 moves up, each pushing inclined edge 241 will push the headrest frame raw material rod 6 placed in the upper supporting groove 231 above it upward, so that each headrest frame raw material rod 6 is separated from the original supporting groove 231, and then slides down along the pushing inclined edge 241 to the next supporting groove 231, thereby completing the feeding of each supporting groove 231 one by one (as shown in Figure 5 ).

[0047] The spacing between adjacent supporting grooves 231 is the same as the spacing between adjacent clamping cylinders 32 (a certain clamping cylinder 32 in the upper layer and the adjacent clamping cylinder 32 in the lower layer). The robotic arm 3 drives each clamping cylinder 32 to extend to the top side of the feeding device 2, and then ten headrest skeleton raw material rods 6 supported by the supporting grooves 231 can be clamped at one time. Subsequently, the robotic arm 3 drives each clamping cylinder 32 to extend to one side of the jig frame 4, and then the ten headrest skeleton raw material rods 6 can be inserted into the respective clamping forks (a straight bar 431 and a bent bar 432) on the same side at one time (refer to Figure 3 ). After the feeding of both sides of the jig frame 4 is completed (as shown in Figure 3 ), the hook 421 of the jig frame 4 can be hooked onto the suspension rod (not shown in the figure) of the annular conveying chain (at point A in Figure 1 ), so that a plurality of jig frames 4 are hung on the annular conveying chain. Subsequently, the annular conveying chain moves, and then the suspension rod moves downward, so that the headrest skeleton raw material rods 6 clamped by the plurality of jig frames 4 are immersed in the U-shaped electroplating tank 1 for electroplating. The annular conveying chain drives each jig frame 4 to move along the U-shaped electroplating tank 1.

[0048] After the electroplating is completed, the jig frame 4 is pulled out, and the robotic arm 3 withdraws the ten electroplated headrest skeleton raw material rods 6 at one time and places them on the conveyor belt 51 for drying.

[0049] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
