DETAILED DESCRIPTION

[0021] This application provides spray paint bracket, please refer to Figure 1-Figure 10 :include, A suspension conveyor line 1, the suspension conveyor line 1 is used to move a workpiece 2; An interference component 3, the interference component 3 is fixedly mounted on the suspension conveyor line 1; The hanger 4 is divided into a movable plate 41 and a fixed plate 42. The suspension conveyor line 1 drives the hanger 4 and the interference assembly 3 to move relative to each other, and the relative movement drives the movable plate 41 to reciprocate in the vertical direction; The transmission component 5 converts the force generated by the relative movement between the hanger 4 and the interference component 3 into a force for the hanger 4 to move up and down. The input end of the transmission component 5 contacts the interference component 3, and the output end of the transmission component 5 contacts the moving plate 41.

[0022] It also includes connecting parts 11 installed on the suspension conveyor line 1, and the connecting parts 11 are provided with several groups, each group of connecting parts 11 has at least two connecting parts, and the connecting parts 11 are arranged in a line. A cross beam 12 is installed under the connecting parts 11, and a fixed plate 42 is installed on both sides of the cross beam 12, and a moving plate 41 is installed in the middle of the fixed plate 42.

[0023] Specifically in practical applications, an automatic touch-up paint nozzle is provided at one end of the suspension conveyor line 1. The suspension conveyor line 1 belongs to the prior art, so it is not described in detail. Through the function of the suspension conveyor line 1, multiple workpieces 2 can be driven to move into the paint spraying room at the same time for painting operation. In this embodiment, the suspension conveyor line 1 is connected to the hanger 4 through 4 connecting members 11, so that the hanger 4 can move stably, and the transmission component 5 is installed on the hanger 4. The movement of the hanger 4 drives the transmission component 5 and the interference component 3 to move relative to each other, and the relative movement therebetween can drive the movable plate 41 to move up and down; when the movable plate 41 and the fixed plate 42 are in the same horizontal position, the fixed plate 42 is relied on to support the workpiece 2. When the movable plate 41 is higher than the fixed plate 42, the movable plate 41 is relied on to support the workpiece 2, and the first coat of painting and drying is performed. After that, the fixed plate 42 switches to the movable plate 41 for support, and the support point with the workpiece 2 can be changed. At this time, the automatic touch-up paint nozzle touches up the contact point between the fixed plate 42 and the workpiece 2, eliminating the need for manual unloading and manual touch-up operations; The cross beam 12 is connected by four groups of connecting members 11, so that the cross beam 12 is in a more stable state.

[0024] Embodiment 1 of the interference assembly 3, referring to Figure 1 , Figure 2 and Fig.10 The interference assembly 3 includes an interference plate 31. There are at least three interference plates 31, one of which is located on the left side of the hanger 4, and the other is located on the right side of the hanger 4, and they are arranged in sequence.

[0025] Specifically in practical applications, the interference plate 31 is a rectangular plate with relatively large friction. When the transmission wheel 126 interferes with the plate 31, it can drive the transmission wheel 126 to rotate. When the interference plate 31 is located on the left side of the bracket 4, it can drive the transmission wheel 126 to reverse. When the interference plate 31 is located on the right side of the bracket 4, it can drive the transmission wheel 126 to rotate forward.

[0026] Embodiment 1 of the transmission component 5, referring to Figure 1 and Figure 2 The transmission component 5 includes a circular hole 121 opened at the center position of the crossbeam 12, a threaded shaft 122 is arranged in the circular hole 121, the threaded shaft 122 passes through the circular hole 121, the movable plate 41 is installed at the lower end of the threaded shaft 122, a first bearing 123 is installed on the crossbeam 12, a rotating tube 124 is installed on the inner ring of the first bearing 123, a nut 125 meshing with the threaded shaft 122 is fixedly installed at the lower end of the rotating tube 124, a transmission wheel 126 is installed at the upper end of the rotating tube 124, the transmission wheel 126 is in contact with the interference plate 31, and a first hole 127 for the threaded shaft 122 to pass through is opened on the rotating tube 124.

[0027] Specifically in practical applications, when the linearly moving transmission wheel 126 contacts the relatively stationary interference plate 31, the transmission wheel 126 rotates forward, and the self-rotation of the transmission wheel 126 drives the rotating tube 124 and the nut 125 to rotate. Through the action of the first bearing 123, the rotating tube 124 rotates stably. A first hole for the threaded shaft 122 to pass through is opened on the rotating tube 124, so that the threaded shaft 122 can move upward. The movable plate 41 is fixedly connected to the threaded shaft 122, and both are in a non-rotatable state. The nut 125 rotates and moves relative to the threaded shaft 122. The nut 125 can drive the threaded shaft 122 to move upward. The threaded shaft 122 drives the movable plate 41 to move upward and can also drive the workpiece 2 to move upward, thereby achieving the purpose of automatically replacing the support point. After the support point is replaced, the paint touch-up and drying operations are performed, and then the transmission wheel 126 contacts the interference plate 31 on the left and reverses to achieve the resetting of the movable plate 41.

[0028] Embodiment 2 of the interference assembly 3, refer to Figures 3 to 9 The interference component 3 includes a lifting plate 32 and a lowering plate 33. The interference component 3 is provided with at least one group. The lifting plate 32 and the lowering plate 33 are each provided with a pair. A load-bearing plate 35 is installed at the lower end of each of the lifting plate 32 and the lowering plate 33. The top view of the cross-section at both ends of the lifting plate 32 and the lowering plate 33 is a trumpet shape 36.

[0029] Specifically in actual applications, the movable plate 41 is initially in the lowest position, and the transmission component 5 first contacts the lifting plate 32, and the lifting plate 32 indirectly drives the transmission component 5 and the movable plate 41 to move upward. At this time, the contact point is replaced, and the paint touch-up and drying operations can be performed; when the transmission component 5 first contacts the lowering plate 33, it can drive the interference component 3 to move downward until it is reset; the load-bearing plate 35 mainly plays a role in supporting the interference component 3, and through the role of the trumpet-shaped plate 36, the crossbeam 12 and the sliding square tube 132 are in a movable or immovable state.

[0030] Embodiment 2 of the transmission component 5, referring to Figures 3 to 9The transmission component 5 includes a square hole 131 opened at the center of the crossbeam 12, a sliding square tube 132 is arranged in the square hole 131, the movable plate 41 is fixedly connected to the lower end of the sliding square tube 132, pulleys 133 are installed on both sides of the upper end of the sliding square tube 132, and the pulleys 133 are in contact with the load-bearing plate 35; an L-shaped locking rod 134 is hingedly installed at the lower end of the sliding square tube 132, and a fixing block 135 is installed on one side of the L-shaped locking rod 134. A through hole 136 is opened on the side wall of the sliding square tube 132, and the fixing block 135 can pass through the through hole 136. The side wall of the square hole 131 is opened There is a limiting groove 137, which is divided into an upper groove 1371 and a lower groove 1372. The fixed block 135 is inserted into the limiting groove 137 through the through hole 136. A compression spring 138 is installed between the L-shaped locking rod 134 and the sliding square tube 132. The compression spring 138 drives the fixed block 135 to insert into the limiting groove 137. A roller 139 is installed on the upper end of the L-shaped locking rod 134. The roller 139 contacts the lifting plate 32 or the lowering plate 33, and the trumpet-shaped 36 drives the roller 139 to move; the height of one end of the load-bearing plate 35 is higher than the height of the other end.

[0031] Specifically in practical applications, the movable plate 41 is at the same level as the fixed plate 42, and the fixed block 135 is inserted into the limit groove 137 through the through hole 136. At this time, the sliding square tube 132 and the crossbeam 12 are in an immovable state. Figure 6 , the roller 139 is located on the right side of the lifting plate 32. When the roller 139 on the L-shaped locking rod 134 contacts the bell-shaped 36, the height of the roller 139 does not change, and the roller 139 can be driven to slide toward the center of the sliding square tube 132. At the same time, the pulley 133 contacts the load-bearing plate 35, and the load-bearing plate 35 supports the pulley 133, the square tube 132, and the movable plate 41. When the roller 139 leaves the bell-shaped 36, the fixed block 135 is completely pulled out of the limiting groove 137. At this time, the sliding square tube 132 and the crossbeam 12 are in a movable state. As the pulley 133 continues to move, the load-bearing plate 35 lifts the pulley 133. The slope and length of the load-bearing plate 35 can be adjusted according to actual conditions to control the overall lifting height. After being lifted to a specified height, the movable plate 41 can lift the workpiece 2 and perform a paint touch-up operation; Figure 6 When the roller 139 moves to the left side of the lifting plate 32 and the roller 139 contacts the bell-shaped 36, the height of the roller 139 does not change, and the bell-shaped 36 gradually releases the roller 139. Under the action of the compression spring 138, the L-shaped locking rod 134 is driven to reset. The L-shaped locking rod 134 resets and drives the fixing block 135 to be inserted into the limiting groove 137. At this time, the sliding square tube 132 and the beam 12 are in an immovable state, and the sliding square tube 132 and the moving plate 41 maintain a relatively high position. At this time, the contact point of the workpiece 2 is replaced, and the paint touch-up operation can be performed; According to actual conditions, the distance between the lifting plate 32 and the lowering plate 33 can be adjusted. After the paint touch-up and drying are completed, the roller 139 passes through the lowering plate 33, and like the above-mentioned lifting plate 32, it is first unlocked (the fixed block 135 leaves the limiting groove 137). Under the guidance of the load-bearing plate 35 and the action of gravity, the sliding square tube 132 and the movable plate 41 automatically lower their heights, and after moving to the other end of the lowering plate 33, they are locked (the fixed block 135 is inserted into the limiting groove 137) to fix the movable plate 41.

[0032] Reference Figure 8 and Fig. 9 A pair of L-shaped locking rods 134 are provided, and the moving directions of the L-shaped locking rods 134 are opposite.

[0033] In practical applications, Figure 8 An L-shaped locking rod 134 is shown in the figure, and one L-shaped locking rod 134 and the movable plate 41 can also be fixed. Fig. 9 Two L-shaped locking rods 134 are shown in the figure and are arranged back to back. The two L-shaped locking rods 134 make the fixing of the movable plate 41 more stable.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A conical protrusion 411 is installed at the lower end of the moving plate 41.

[0035] Specifically, in practical applications, the conical protrusions 411 can prevent the moving plate 41 and the fixed plate 42 from sticking to each other, and a certain gap can be retained.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The material of the transmission wheel 126 and the interference plate 31 has a large friction force.

[0037] Specifically, in practical applications, increasing the friction between the transmission wheel 126 and the interference plate 31 can improve the friction therebetween, and changing the shape of the transmission wheel 126 can also adjust the friction coefficient.
