DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: This example is intended to promote the solution of the problem that the existing manipulator spraying equipment usually has only one nozzle, which results in a limited spraying range when spraying objects. Figures 1-4 A robotic arm spraying device includes a robotic arm body 110, a mounting block 111 is installed on the robotic arm body 110, a support rod 112 is installed on the mounting block 111, a spray plate 113 is provided on the front side of the support rod 112, a plurality of spray heads 114 are provided on the spray plate 113, a cavity 115 is opened in the support rod 112, a bidirectional screw rod 120 is provided in the cavity 115, a rack 121 corresponding to the bidirectional screw rod 120 is installed outside the spray plate 113, the rack 121 is engaged with the bidirectional screw rod 120, and the end of the bidirectional screw rod 120 is transmission-connected to a drive motor 122.

[0023] When the device is in operation, the manipulator is manually turned on through a controller or a control panel. At this time, the paint enters the spray plate 113 through the paint tube, and then is sprayed from the spray head 114 on the spray plate 113, thereby spraying the paint on the object. The paint tube and the entry of the paint in this embodiment are not limited and can be configured accordingly according to needs. At the same time, the manipulator body 110 mentioned in this embodiment is a conventional technical means and is not the focus of this case, so its specific working principle will not be explained in detail.

[0024] When it is necessary to spray objects over a large area, the motor is turned on to control the rotation of the bidirectional screw 120, so that the rack 121 on the outside of the spray plate 113 is engaged with the bidirectional screw 120, thereby driving one end of the two spray plates 113 from the outside to the middle. At this time, since the spray plate 113 is set as an arc plate, the other ends of the two sprays will expand outward. At the same time, there are several spray heads 114, so the spraying angle is increased, which can improve work efficiency when spraying objects over a large area.

[0025] When it is necessary to spray an object of a small area, or when it is necessary to retract the spray plate 113, the driving motor 122 is controlled to drive the bidirectional screw rod 120 to rotate in the opposite direction, so that the spraying angle can be reduced.

[0026] A sealing ball 131 is installed on the side of the limiting ring 130 near the spray head 114. The sealing ball 131 is set to a rubber ball, so that the spray plate 113 can be more stable when adjusting the angle. Through the setting of the sealing ball 131, when adjusting the spraying angle, the spray head 114 on the inner side of the spray plate 113 can be temporarily sealed, thereby preventing the paint from being sprayed inside the limiting ring 130, resulting in waste of paint.

[0027] The bearing 125 is provided in the limiting groove 124 and the support sleeve is provided on the outside of the rotating rod 123, so that the driving motor 122 can be more stable when controlling the bidirectional screw rod 120 to rotate.

[0028] In this embodiment: through the arc design and angle adjustment mechanism of the spray plate 113, the work efficiency can be improved during large-area spraying. At the same time, the spraying angle can be adjusted according to the size of the spraying object and the spraying requirements, which is more adaptable. Through the setting of the blocking ball 131, the waste of paint caused by the adjustment of the spraying angle is reduced. The design of the limit ring 130 and the bearing 125 improves the stability of the equipment during operation and ensures the spraying quality.

[0029] Example 2: This example is intended to solve the problem of the support rod 112 and the spray plate 113 moving or shaking when the manipulator is working. This example is an improvement made on the basis of Example 1. For details, please refer to Figures 1-4The front side of the mounting block 111 is provided with a fixing plate 140. The fixing plate 140 is provided with a fixing groove 141 corresponding to the support rod 112. The support rod 112 engages with the fixing groove 141. A clamping block 142 is installed in the fixing groove 141. The support rod 112 is provided with a clamping groove 143 corresponding to the clamping block 142. The clamping block 142 engages with the clamping groove 143. The clamping mechanism between the clamping block 142 and the clamping groove 143 simplifies the installation and adjustment process of the spray plate 113, making the assembly and maintenance of the equipment more convenient. This also improves the working efficiency and ease of use of the equipment.

[0030] In this embodiment: by providing a fixing groove 141 matching the support rod 112 on the fixing plate 140, and installing a clamping block 142 in the fixing groove 141, the clamping groove 143 on the support rod 112 cooperates with the clamping block 142, so that the support rod 112 can be effectively fixed on the fixing plate 140, avoiding the support rod 112 and the spray plate 113 from moving or shaking when the manipulator is working. Through the engagement of the clamping block 142 and the clamping groove 143, the manipulator body 110 and the support rod 112 are precisely connected, thereby improving the stability and accuracy of the spray angle adjustment.

[0031] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
