Description

Technical Field

[0001] The present application relates to a molding device for an electrical box cover, and in particular to a fiber cloth grabbing device for a spray molding and pressing process of an electrical box cover. Background Art

[0002] The spray molding process involves mixing component A and component B resins and evenly spraying them onto the surface of the fiber cloth. The fiber cloth is then placed in a mold on a press for compression molding. Spraying onto the fiber surface is crucial in this process, ensuring uniformity of the resin applied. Currently, manual handling of the fiber cloth presents several challenges: 1. It requires two people, increasing labor costs; 2. Poor spraying consistency leads to poor product consistency.

The six-axis manipulator is used to drive the fiber cloth to move to the bottom of the sprayer and move the fiber cloth along a preset horizontal trajectory, so that the resin is evenly sprayed on the fiber cloth.

[0007] The above-mentioned application is a fiber cloth grasping device for the spray molding process of the electrical box cover. The fiber cloth on the workbench can be clamped by the chuck assembly. The six-axis robot can drive the fiber cloth to the bottom of the sprayer and move the fiber cloth horizontally along a preset trajectory. In this way, the resin sprayed by the sprayer can be evenly distributed on the fiber cloth. Compared with manual grasping, it can reduce labor intensity and improve product consistency.

[0008] In some embodiments, the movable arm is slidably connected to the fixed base via a linear guide rail, and the driving device is two cylinders respectively connected to the two movable arms.

[0009] In some embodiments, a cushion pad is further provided on the fingers of the pneumatic gripper. The cushion pad is mainly used to prevent the pneumatic gripper from pinching the fiber cloth, and the cushion pad can be made of materials such as silicone and rubber.

[0010] In some embodiments, the left and right sides of the workbench are open to allow two movable arms to enter from the left and right for clamping. Upwardly raised limit plates are provided on the front and rear sides of the workbench to limit the front and rear position of the limit cloth. The workbench body can be made of steel.

[0019] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings. The terms used in the implementation methods of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0020] See Figures 1 to 5 The present invention provides a fiber cloth grabbing device for the spray molding process of an electrical box cover, which is characterized by comprising a workbench 2 for placing a fiber cloth 1, a sprayer 3 for spraying resin, and a grabbing mechanism 4 for grabbing the limiting cloth on the workbench 2 to the bottom of the sprayer 3 and driving the fiber cloth 1 to move horizontally; the grabbing mechanism 4 includes a chuck assembly 41 for grabbing the fiber cloth 1, and a six-axis manipulator 42 connected to the chuck assembly 41;

[0021] The chuck assembly 41 includes a fixed base 411, two movable arms 412 slidably connected to the fixed base 411 so as to move toward or away from each other, a driving device 413 mounted on the fixed base 411 for driving the two movable arms 412 to move toward or away from each other, and a plurality of pneumatic clamps 414 fixedly mounted on the two movable arms 412 and capable of opening and closing. Thus, the two movable arms 412 of the chuck assembly 41 can clamp the two side edges of the fiber cloth 1. The six-axis manipulator 42 is used to drive the fiber cloth 1 to move below the sprayer 3 and move the fiber cloth 1 along a preset horizontal trajectory so that the resin is evenly sprayed on the fiber cloth 1. The specific horizontal movement trajectory of the fiber cloth 1 can be referred to. Figure 5 The number of pneumatic grippers 414 on each movable arm 412 can be increased or decreased according to the length of the fiber cloth 1. Specifically, the number of pneumatic grippers 414 is not less than 5, and the pneumatic grippers 414 on the movable arm 412 are evenly spaced along the length direction thereof.

[0022] The gripping device can clamp the fiber cloth 1 located on the workbench 2 through the chuck assembly 41. The six-axis manipulator 42 can drive the fiber cloth 1 to move to the bottom of the sprayer 3 and move the fiber cloth 1 horizontally along a preset trajectory. In this way, the resin sprayed by the sprayer 3 can be evenly distributed on the fiber cloth 1. Compared with manual gripping, it can reduce labor intensity and improve product consistency.

[0023] The movable arm 412 is slidably connected to the fixed base 411 via a linear guide rail 415 , and the driving device 413 is two cylinders respectively connected to the two movable arms 412 .

[0024] The fingers of the pneumatic clamping jaws 414 are further provided with a buffer pad 4141. The buffer pad 4141 is mainly used to prevent the pneumatic clamping jaws 414 from pinching the fiber cloth 1. The buffer pad 4141 can be made of materials such as silicone and rubber.

[0025] The left and right sides of the workbench 2 are open, allowing two movable arms 412 to enter from the left and right for clamping. Upwardly raised limit plates 21 are provided on the front and rear sides of the workbench 2 to limit the front and rear position of the fiber cloth. The main body of the workbench 2 can be made of steel. To ensure stable placement of the fiber cloth 1, at least one plate 22 is installed on the steel. These plates 22 are bent upward to form the limit plates 21.

[0026] The following briefly describes the working process and usage of the fiber cloth 1 grabbing device in the spray molding and molding process of the electrical box cover in the above embodiment:

[0027] Place the fiber cloth 1 on the workbench 2, and the six-axis manipulator 42 drives the chuck assembly 41 to move to the fiber cloth 1. The two cylinders retract, and the two movable arms 412 move relatively close to each other and move to the appropriate position. The pneumatic fingers clamp the fiber cloth 1, and then the six-axis manipulator 42 moves the fiber cloth 1 under the nozzle of the sprayer 3. The six-axis manipulator 42 moves horizontally with the fiber cloth 1, so that the resin sprayed by the sprayer 3 is evenly distributed on the fiber cloth 1. It is best that the six-axis manipulator 42 sends the fiber cloth 1 sprayed with resin to the next process for molding to make the electrical box cover.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present application, rather than to limit them. Although the embodiments of the present application have been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
