DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides an embodiment: a shielding device for spraying workpieces, comprising an operating table 1 and a transport chain 3, wherein the operating table 1 is provided with the transport chain 3, a spraying assembly 2 is provided at the front end of the operating table 1, the spraying assembly 2 comprises a fixing rod 201, a spray head 202 and an infrared sensor 203, a fixing assembly 4 is provided on the surface of the transport chain 3, and a shielding assembly 7 is provided in the operating table 1;

[0025] A pallet 401 is fixedly installed on the surface of the transport chain 3, a placing platform 403 is movably connected inside the pallet 401, a servo motor 402 is fixedly connected to the bottom center of the placing platform 403, four sets of slide grooves 404 are symmetrically opened inside the placing platform 403, a slider 405 is movably connected inside the slide groove 404, a first spring 406 is arranged inside the slider 405, the two ends of the first spring 406 are respectively against the slide groove 404 and the slider 405, the upper end of the slider 405 is fixedly connected to a limit block 407, a clamping block 408 is arranged outside the limit block 407, the clamping block 408 is arc-shaped, and a positioning component 5 is arranged inside the limit block 407. Figure 3 As shown, when the workpiece moves downward, the inner side of one end of the workpiece presses against the inclined surface of the clamping block 408, causing the limit block 407 to move toward the center of the placement table 403. At the same time, the slider 405 pushes the first spring 406 to deform. When the bottom of the workpiece is completely in contact with the placement table 403, the first spring 406 rebounds to make the clamping block 408 fit tightly against the inner wall of the workpiece, thereby facilitating the clamping and limiting of the workpiece.

[0026] The positioning assembly 5 includes a movable groove 501, a movable block 502, a second spring 503 and a connecting block 504. The movable groove 501 is provided in the limit block 407, and the movable block 502 is movably connected in the movable groove 501. The second spring 503 is provided on the upper side of the movable block 502. The two ends of the second spring 503 are respectively against the movable groove 501 and the movable block 502. The outer side of the movable block 502 is rotatably connected to the connecting block 504, and the connecting block 504 is connected to the clamping block 408. The edge of the limit block 407 is rounded. Figure 5 As shown, this structure is used for moving the workpiece upward, the clamping block 408 and the limit block 407 fit together to move the workpiece, and the clamping block 408 is driven to move upward by being connected to the movable block 502 through the connecting block 504. When moving to the top, the clamping block 408 is rotatably connected to the movable block 502. Since the top is rounded, the clamping block 408 rotates inward, which facilitates the removal of the workpiece and avoids wear on the inside of the workpiece, which affects the appearance.

[0027] The device solves the problem that it is inconvenient to fix workpieces of different sizes when placing them during spraying, and the lack of limiting the workpieces may cause the workpieces to be placed unstably, thus affecting the spraying quality, by setting the fixing component 4 and the positioning component 5.

[0028] Furthermore, the shielding assembly 7 includes a pneumatic push rod 701, a baffle 702 and a guide rod 703. Two groups of pneumatic push rods 701 are fixedly installed on the upper and lower sides of the inner wall of the operating table 1. The baffle 702 is fixedly connected to the opposite side of the pneumatic push rod 701. Two groups of guide rods 703 are fixedly connected to the upper and lower sides of the inner wall of the operating table 1. The guide rods 703 pass through the baffle 702. Figure 4As shown, the structure is used to push the baffle 702 to move toward the center along the guide rod 703 through the pneumatic push rod 701, and adjust according to the shielding position. The two sets of baffles 702 are convenient for adapting to different shielding requirements, thereby enhancing the applicability of the device.

[0029] Furthermore, two groups of fixed rods 201 are fixedly connected in the operating table 1. A nozzle 202 is movably connected to the surface of one group of fixed rods 201. The angle between the nozzle 202 and the fixed rods 201 is 90 degrees. An infrared sensor 203 is fixedly installed on the surface of the other group of fixed rods 201. The infrared sensor 203 is connected to the nozzle 202 by wires. Figure 2 As shown, the structure is used to connect the infrared sensor 203 with the nozzle 202 through the wire. When the infrared sensor 203 detects the workpiece, the nozzle 202 is started to realize indirect spraying, save spraying materials and avoid waste.

[0030] Furthermore, a positioning rod 6 is threadedly connected to the center of the placement platform 403, and the limit block 407 is symmetrically arranged around the positioning rod 6. The slide block 405 is T-shaped and matches the slide groove 404. Figure 3 As shown, the structure is used to facilitate adjustment through the threaded positioning rod 6, and to provide a certain support to the top of the workpiece to enhance stability. The slider 405 allows the limit block 407 to move stably in the slide groove 404 to avoid escaping from the slide groove 404.

[0031] Furthermore, two groups of scale lines are set on the upper and lower sides with the center of the surface of the guide rod 703 as the starting point, and a hole matching the guide rod 703 is opened in the baffle 702. Figure 4 As shown, the structure is used to accurately locate the shielding size while the baffle 702 moves along the guide rod 703, thereby improving the accuracy of spraying and meeting different spraying requirements.

[0032] Working principle: When used, Figure 3 As shown, when the workpiece moves downward, the inner side of one end of the workpiece presses against the inclined surface of the clamping block 408, so that the limiting block 407 moves toward the center direction of the placement table 403, and at the same time, the first spring 406 is pushed to deform through the slider 405. When the bottom of the workpiece is completely in contact with the placement table 403, the clamping block 408 is tightly in contact with the inner wall of the workpiece under the rebound action of the first spring 406, so that the workpiece can be clamped and limited, and the transport chain 3 is started to transport the workpiece. Figure 2 and Figure 4 As shown, first adjust according to the spraying position, start the pneumatic push rod 701 to push the baffle 702 to move toward the center along the guide rod 703, and after moving to the specified position, when the infrared sensor 203 detects the workpiece, start the nozzle 202, and at the same time, the servo motor 402 drives the placement table 403 to rotate, so that the workpiece rotates, and the workpiece is indirectly sprayed. After the spraying is completed, as shown in FIG. Figure 5 As shown, when the workpiece moves upward, the clamping block 408 fits with the limit block 407 to enable the workpiece to move, and the clamping block 408 is driven to move upward by being connected to the movable block 502 through the connecting block 504. When the workpiece moves to the top, the clamping block 408 is rotatably connected to the movable block 502. Since the top is rounded, the clamping block 408 rotates inward, which facilitates the removal of the workpiece and avoids wear on the inside of the workpiece. The above is the entire working principle of the utility model.
