[0056] The testing machine is provided with a testing hopper, and a positioning groove is arranged in the testing hopper. To meet different processing requirements, some testing hoppers are horizontally arranged, and their positioning grooves are also horizontal, and horizontal material pipes need to be placed. Some testing hoppers are inclined, and their positioning grooves are also correspondingly inclined, and inclined material pipes need to be placed. The feeding device in the prior art can only convey the material pipes into the horizontally arranged testing hoppers and cannot cooperate with the inclined testing hoppers to place the material pipes obliquely, resulting in the inability to align the positioning grooves in the testing hoppers during the placement of the material pipes. And in order to enable the suction plate to adsorb the middle position of the material pipe so that the material pipe can remain balanced during transportation, the module structure for driving the suction plate to move usually includes a transverse movement module, a longitudinal movement module and a vertical movement module to drive the suction plate to move horizontally, longitudinally and vertically, with a relatively complex structure and high cost.

[0057] The following is a preferred embodiment of a feeding device and a feeding equipment for a testing machine provided by the present invention, which can solve the above technical problems.

[0058] Please refer to Figure 1 , the preferred embodiment of the present invention provides a feeding equipment for a testing machine, which includes a support frame 2 and a feeding device 1.

The bottom plate 11 is arranged on the lateral side of the testing hopper 3. The two lateral sides of the bottom plate 11 are respectively a first side 111 and a second side 112, and the second side 112 is closer to the testing hopper 3 than the first side 111. The conveying device 12 is arranged below the bottom plate 11, and the conveying device 12 is used to convey the material pipe from the first side 111 to the second side 112.

[0060] Please refer to Figure 2 and Figure 8, the pick-and-place manipulator 13 includes a pick-and-place assembly 131, a rotary cylinder 132, a transverse module 133, and an inclined module 134. The pick-and-place assembly 131 is movably disposed at the second side 112. It includes a suction plate 1311 and a telescopic cylinder 1312. The suction plate 1311 is used to adsorb the material tube. The telescopic rod of the telescopic cylinder 1312 is vertically connected to the suction plate 1311 and is used to drive the suction plate 1311 to move. The rotary cylinder 132 is connected to the telescopic cylinder 1312 and is used to drive the telescopic cylinder 1312 and the suction plate 1311 to rotate. The transverse module 133 is disposed along the transverse direction. It is connected to the rotary cylinder 132 and is used to drive the rotary cylinder 132 and the pick-and-place assembly 131 to move transversely between the material taking position and the material placing position. When the pick-and-place assembly 131 is at the material taking position, the suction plate 1311 is parallel to the bottom plate 11 and is located above the conveying device 12. When the pick-and-place assembly 131 is at the material placing position, the pick-and-place assembly 131 is located above the test hopper 3, and the suction plate 1311 rotates to be parallel to the bottom surface of the test hopper 3 under the drive of the rotary cylinder 132. The inclined module 134 is inclined to the longitudinal direction and the vertical direction. The bottom end of the inclined module 134 is connected to one end of the bottom plate 11 in the longitudinal direction. The top end of the inclined module 134 inclines towards the other end of the bottom plate 11 in the longitudinal direction. The inclined module 134 is connected to the transverse module 133 and is used to drive the rotary cylinder 132 and the pick-and-place assembly 131 to move in a direction inclined to the longitudinal direction and the vertical direction.

[0061] For the feeding device 1 of the present utility model and the feeding equipment for the testing machine, first, the material tubes are conveyed one by one from the first side 111 to the second side 112 through the conveying device 12. Then, the pick-and-place assembly 131 moves to the material taking position. After the telescopic cylinder 1312 drives the suction plate 1311 to move forward to suck the material tube, it drives the suction plate 1311 to retract. During the process of the pick-and-place assembly 131 moving to the material taking position, the transverse module 133 can drive the suction plate 1311 to move transversely, and the inclined module 134 can drive the suction plate 1311 to move simultaneously in the vertical and longitudinal directions, so that the pick-and-place assembly 131 can reach above the material tube, and the suction plate 1311 can suck the middle position of the material tube. Subsequently, the pick-and-place assembly 131 moves to the material placing position. The rotary cylinder 132 drives the telescopic cylinder 1312 and the suction plate 1311 to rotate, so that the inclination angle of the material tube is consistent with the inclination angle of the bottom surface of the test hopper 3. After the telescopic cylinder 1312 drives the suction plate 1311 to move forward to place the material tube in the positioning groove of the test hopper 3, it drives the suction plate 1311 to retract. The pick-and-place assembly 131 moves to the material taking position again to convey the next material tube. For the feeding device 1 of the present utility model and the feeding equipment for the testing machine, through the inclined module 134, the vertical and longitudinal displacements of the suction plate 1311 can change simultaneously, so that the suction plate 1311 can suck the middle position of the material tube, thus making the overall structure simple and easy to process. At the same time, the rotary cylinder 132 can drive the suction plate 1311 to rotate, so that the suction plate 1311 can adsorb the horizontally placed material tube and place it obliquely into the positioning groove in the test hopper 3, effectively improving the working efficiency.

[0062] Please refer to Figure 4 and Figure 5 The feeding device 1 further includes a first connection assembly 14, which includes a connection block 141. The bottom surface of the connection block 141 is connected to one end of the bottom plate 11 close to the tilting module 134. An inclined connection surface 1411 is provided on the side of the connection block 141 facing the conveying device 12. The top end of the connection surface 1411 is inclined away from the conveying device 12, and the connection surface 1411 is connected to the bottom surface of the tilting module 134. In the above structure, the tilting module 134 and the bottom plate 11 are connected by the connection block 141, so that the angle between the tilting module 134 and the bottom plate 11 remains unchanged, and the structure is stable.

[0063] Please refer to Figure 4 、 Figure 5 and Figure 6 The first connection assembly 14 further includes two support sheet metals 142, which are respectively arranged on both sides of the connection between the tilting module 134 and the bottom plate 11.

The first sheet metal 1421 is connected to the side surface of the tilting module 134, and the second sheet metal 1422 is connected to the side surface of the bottom plate 11. In the above structure, the connection between the tilting module 134 and the bottom plate 11 can be strengthened by the support sheet metal 142, making the connection between the two more stable.

[0064] Please refer to Figure 6 The support sheet metal 142 further includes a connection sheet metal 1423 and a reinforcing rib 1424.

The reinforcing rib 1424 is triangular, its bottom edge is connected to the connection sheet metal 1423, and its side edge is connected to the first sheet metal 1421. The two side surfaces of the bottom plate 11 protrude from the two side surfaces of the tilting module 134. In order to make the first sheet metal 1421 fit the side surface of the tilting module 134 and make the second sheet metal 1422 fit the side surface of the bottom plate 11, the first sheet metal 1421 and the second sheet metal 1422 need to be connected by the connection sheet metal 1423, making the support sheet metal 142 in a stepped shape.

Then, the picking and placing assembly moves to the material picking position. After the telescopic cylinder drives the suction plate to move forward to suck the material tube, it drives the suction plate to retract.

Subsequently, the picking and placing assembly moves to the material placing position, and the rotary cylinder drives the telescopic cylinder and the suction plate to rotate, so that the tilting angle of the material tube is the same as the tilting angle of the bottom surface of the testing hopper. After the telescopic cylinder drives the suction plate to move forward to place the material tube in the positioning groove of the testing hopper, it drives the suction plate to retract, and the picking and placing assembly moves to the material picking position again to convey the next material tube. For the feeding device of the present utility model and the feeding equipment for a testing machine, the tilting module can cause the vertical and longitudinal displacements of the suction plate to change simultaneously, so that the suction plate can suck the middle position of the material tube, thereby making the overall structure simple and easy to process. At the same time, the rotary cylinder can drive the suction plate to rotate, so that the suction plate can adsorb the horizontally placed material tube and tilt it into the positioning groove in the testing hopper, effectively improving the working efficiency.
