Specific embodiments

[0020] The following will describe the embodiments of the present invention in conjunction with the accompanying drawings and related embodiments. The embodiments of the present invention are not limited to the following embodiments, and the relevant necessary components of the present invention in the technical field should be regarded as well-known technologies in the technical field and can be known and mastered by those skilled in the technical field.

[0021] The present invention discloses a robotic arm automatic feeding mechanism for a template machine, as Figures 1 - 4 shown in combination. The robotic arm automatic feeding mechanism 1 is arranged outside the feeding area 211 of the template machine 2 close to the workbench 21. The robotic arm automatic feeding mechanism 1 includes a base 11, a divider 12, a connecting arm 13 and a driving device 14. The base 11 is located outside the feeding area 211. The divider 12 is arranged in the middle of the top surface of the base 11. The output end of the divider 12 is vertically upward and connected to one end of the connecting arm 13. Both sides of the bottom end of the driving device 14 are output ends, and one of the output ends is at the other end of the connecting arm 13. The other output end of the driving device 14 is connected to the feeding device 3 through a joint. The output end of the driving device 14 connected to the connecting arm 13 is the output end for performing a rotational movement. The output end of the driving device 14 connected to the feeding device 3 is the output end for performing a rotational movement and a lifting movement.

[0022] Specifically, the divider 12 in the robotic arm automatic feeding mechanism 1 rotates the connecting arm 13 horizontally with the position where its output end is connected to the connecting arm 13 as the rotation center, enabling both the driving device 14 and the feeding device 3 to move within the space above the feeding area 211. Then, the driving device 14 can rotate with the position where it is connected to the connecting arm 13 as the center, adjusting its own position relative to the connecting arm 13, thereby adjusting the position of the feeding device 3. Further, by rotating or lifting the output end of the driving device 14 connected to the feeding device 3, the position of the feeding device 3 within the space above the feeding area 211 can be further adjusted. That is, the divider 12, the connecting arm 13, and the driving device 14 together form a robotic arm structure. The divider 12, the connecting arm 13, the driving device 14, and other components on this robotic arm structure can be configured corresponding to the structural components of a SCARA robot. The connection methods, driving principles, and functions achieved among the various components on this robotic arm structure can all refer to the component connection methods, driving principles, and functions of a SCARA robot.

[0023] It should be further noted that when there is a template with materials in the feeding area 211, the feeding device 3 pulls the template located in the feeding area 211. After the feeding device 3 pulls the template, under the drive of this robotic arm structure, it can transfer the template in the feeding area 211 to the feeding device 5 on the template machine 2, thereby realizing the function of automatically feeding the template from the feeding area 211 to the feeding device 5. During this process, through the rotation and height change of the robotic arm structure, the template moves on the workbench 21 while keeping its placement angle relative to the longitudinal and transverse directions of the workbench 21 unchanged, and the moving mode of the template is linear movement. This enables the entire edge part on one side of the template to be pulled by the feeding device 5 after the template is transferred to the workbench 21 close to the feeding device 5, which is beneficial for the feeding device 5 to keep the position of the template stable during the transmission of the template, avoiding the situation of position deviation of the template during the transmission process, and ensuring the yield rate of the template machine 2.

[0024] In addition, the robotic arm structure can drive the feeding device 3 to move to multiple positions within the space, enabling the robotic arm automatic feeding mechanism 1 to perform automatic feeding operations on the template machines 2 at two or more workstations, being applicable to template machines 2 of different production scales and capable of meeting the requirements of different production scale template machines 2 for automatic material transportation.

[0025] As one of the embodiments of the above embodiment, as Figure 1 shown, the feeding device 3 includes a positioning frame 31 and suction cups 32. The positioning frame 31 is connected to the driving end of the driving device 14 on the side away from the connecting arm 13 through a joint, and the positioning frame 31 is connected with a plurality of suction cups 32.

[0026] Among them, several suction cups 32 provided on the positioning frame 31 move downward driven by the driving device 14 and adsorb on the edge of one side of the template, so as to traction the template and cooperate with the robotic arm structure to realize the automatic loading operation of the template.

[0027] As a further preference of the above embodiment, as Figure 1 shown, the positioning frame 31 is provided with a plurality of waist-shaped holes 311 spaced along the length direction of the positioning frame 31, and the connecting end of the suction cup 32 is fixedly connected to the waist-shaped holes 311 through a connecting piece.

[0028] Among them, by adjusting the position where the connecting piece connected to the connecting end of the suction cup 32 is fixed in the waist-shaped hole 311, the connection position of the suction cup 32 on the positioning frame 31 can be adjusted to adapt to the traction requirements of templates of different specifications and sizes.

[0029] As a further preference of the above embodiment, as Figure 1 shown, the output end of the driving device 14 connected to the positioning frame 31 is provided with a ball screw 141. The upper and lower ends of the ball screw 141 both penetrate outside the housing of the driving device 14, and the joint is connected to the bottom end of the ball screw 141.

[0030] Among them, the driving device 14 drives the ball screw 141. In addition to realizing the height adjustment of the loading device 3 for traction of the template, the positioning frame 31 can also be rotated to adjust the position of the positioning frame 31 to ensure that the template can move in a manner that the placement angle in the longitudinal and transverse directions relative to the workbench 21 remains unchanged.

[0031] Preferably, as Figure 1 shown, limit blocks 142 are provided outside the ball screw 141 at the top end of the ball screw 141 and above the joint.

[0032] Among them, the setting of the limit blocks 142 can prevent the ball screw 141 from exceeding the stroke and prevent the positioning frame 31 from colliding with the housing of the driving device 14 and being damaged.

[0033] As one of the embodiments of the above embodiment, as Figure 1 、 Figure 2 and Figure 5 shown in combination, both the driving device 14 and the divider 12 are provided with interface ends 4. The interface ends 4 are connected with cables 41 and air nozzles 42. The top surface of the base 11 is provided with a through hole 111, and an electric control box 112 is arranged inside the base 11. The electric control box 112 is electrically connected with the cable 41.

[0034] Among them, the electric control box 112 is connected to the driving device 14 and the divider 12 through the cable 41, so as to transmit electric energy and control instructions to the driving device 14 and the divider 12. The air nozzle 42 provides a connection position for the driving device 14 and the divider 12 to access a power source with pneumatic force as the driving force, so that the driving device 14 and the divider 12 obtain power.

[0035] As one of the embodiments of the above embodiment, as Figure 1 and Figure 5 Combined as shown, a plurality of Furniture casters 15 are arranged at the bottom of the base 11 in a matrix distribution.

[0036] Among them, through the Furniture casters 15 arranged on the base 11, the movement of the base 11 can be realized, so as to realize the movement of the entire robotic arm automatic feeding mechanism 1. When the robotic arm automatic feeding mechanism 1 breaks down or needs to be moved to other template machines 2 for use, it is convenient for the operator to move the robotic arm automatic feeding mechanism 1.

[0037] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
