[0038] Refer to the attached Figure 1 To Attachment Figure 5 As shown, an embodiment of the utility model provides a feeding device, which is applied to a material assembly machine that can install the parts of an automobile radiator to a preset position. The material assembly machine also includes a feeding device and an assembly device. The feeding device is located upstream of the feeding device. The feeding device can push the parts to a fixed area of ​​the feeding device through a push plate. The feeding device fixes the parts and then transports the parts to the assembly device. In this embodiment, the feeding device can transport the parts to a preset horizontal height so that the mechanical gripper in the assembly device can automatically clamp the parts and install them in the preset installation position of the radiator to complete the installation of the parts in the radiator. It should be noted that the utility model is not limited to the field of automobile radiator radiators, and the feeding device and the material assembly machine can also be used to install parts in other structures.

[0039] Specifically, the loading device includes a fixed bracket 1, a flip assembly 2 and a loading plate 3. The fixed bracket 1 is fixedly arranged between the feeding device and the assembly device, the flip assembly 2 is installed on the fixed bracket 1, and is transmission-connected to the flip fulcrum 31 of the loading plate 3. The loading plate 3 is provided with a receiving bin 32, which is located at one end of the loading plate 3 close to the feeding device. After the feeding device pushes the parts to the receiving bin 32 of the loading plate 3, the parts are clamped by the fixing parts installed on the loading plate 3, and then the loading plate 3 is flipped from the horizontal state to the vertical state by the flip assembly 2 (refer to Figure 1 or Figure 2 The mechanical gripper in the docking assembly device takes the component out of the loading plate 3, thereby completing the loading. The flip assembly 2 then controls the loading plate 3 to flip from a vertical state to a horizontal state to continue loading the next component.

[0040] refer to Figure 1 As shown, the flip assembly 2 provided in this embodiment includes a rotating shaft 21, a crank 22 and a cylinder driving member 23. The rotating shaft 21 is rotatably mounted on the fixed bracket 1, one end of the crank 22 is fixedly connected to the rotating shaft 21, and the other end of the crank 22 is connected to the piston telescopic rod of the cylinder driving member 23. When the piston telescopic rod reciprocates and retracts, it can drive the rotating shaft 21 to rotate clockwise or counterclockwise, thereby driving the loading plate 3 to reciprocate and flip, and realize loading and resetting. The cylinder driving member 23 has a simple structure and stable working performance, which can not only save installation space and reduce costs, but also facilitate maintenance.

[0041] During actual use, due to its large mass, the loading plate 3 structure is prone to shaking at the end where the receiving bin 32 is located when the loading is returned from a vertical state to a horizontal state, or from a horizontal state to a vertical state, resulting in unstable operation of the entire loading device and the inability to accurately and continuously supply parts to the downstream assembly device, thereby affecting the assembly efficiency.

[0042] Based on this, in order to balance the bending moment caused by gravity and reduce the impact torque generated during the reversal of the loading plate 3, in this embodiment, Figure 1 and Figure 2 As shown, the feeding device further includes a counterweight 4, which is arranged on one end of the feeding plate 3 away from the feeding device, so that the moment at the position of the counterweight 4 on the feeding plate 3 can be offset by the moment at the position of the receiving bin 32 on the feeding plate 3. In this way, in the process of the feeding plate 3 returning from a vertical state to a horizontal state, or from a horizontal state to a vertical state, the counterweight 4 can balance the gravity moment, thereby reducing the shaking of the feeding plate 3, improving the stability of the feeding process of the feeding plate 3, and effectively ensuring the feeding efficiency of the entire feeding device.

[0043] In this embodiment, reference Figure 3 As shown, the crank 22 is an L-shaped plate structure, and the corner portion 221 of the crank 22 is rotatably connected to the rotating shaft 21. One end of the crank 22 is transmission-connected to the telescopic rod of the cylinder driving member 23, and the other end of the crank 22 is connected to the counterweight 4. By installing the counterweight 4 on the crank 22, the gravity torque between the other end of the crank 22 and the corner portion 221 of the crank 22 can be increased, so that the counterweight 4 indirectly limits the rotating shaft 21 from swinging with the loading plate 3 by limiting the rotation of the corner portion 221 with the rotating shaft 21, so that the maximum gravity torque of the loading plate 3 can be balanced by the counterweight 4. At the same time, the other end of the crank 22 can install the counterweight 4 in a reasonable space in the loading device, so that the structure of the entire loading device is more compact and the layout is more reasonable.

[0044] In this embodiment, the weight counterweight 4 can adjust the overall weight according to the needs. Figure 2 , Figure 4 As shown, the counterweight member 4 includes a counterweight fixing shaft 41, a connecting member 42 and a plurality of counterweight weights 43, wherein the counterweight fixing shaft 41 is connected to the other end of the crank 22 through the connecting member 42, and the plurality of counterweight weights 43 are detachably arranged on the counterweight fixing shaft 41, so that the weight of the entire counterweight member 4 can be adjusted by setting different numbers of counterweight weights 43, and the structure of the entire counterweight member 4 is simple, which simplifies the structure and facilitates the operation of the staff.

[0045] It should be noted that when multiple counterweights 43 are provided, counterweights 43 of different thicknesses can be installed on the counterweight fixing shaft 41. For example, counterweights 43 of different weights such as 5kg, 10kg, 15kg, 20kg, etc. can be freely combined so that the counterweight piece 4 can meet the weight requirement, thereby providing a more flexible option for the staff to adjust the weight of the counterweight piece 4.

[0046] More specifically, a threaded connection portion is provided on the counterweight fixing shaft 41, and the counterweight 43 is sleeved on the counterweight fixing shaft 41, and the bottom surface of the counterweight 43 is fitted and connected with a limit nut, and the limit nut is threadedly connected to the threaded connection portion, so that the counterweight 43 is stably installed on the counterweight fixing shaft 41. In addition, when the weight of the counterweight 4 needs to be adjusted, it is only necessary to screw and remove the limit nut, and then increase or decrease the number of the counterweight 43 sleeved on the counterweight fixing shaft 41, and finally screw and install the limit nut, which further reduces the difficulty of adjustment.

[0047] Specifically, combined Figure 3 , Figure 5 As shown, the other end of the crank 22 is provided with a first connection hole 222, and one end of the counterweight fixing shaft 41 is provided with a second connection hole 411; in addition, the connecting member 42 includes a half-thread bolt 421 and a nut 422, the rod of the half-thread bolt 421 is passed through the first connection hole 222 and the second connection hole 411, the threaded section on the rod is connected to the nut 422, and the bare rod section on the rod is rotatably connected to the first connection hole 222 and the second connection hole 411. Through the above arrangement, when the piston telescopic rod of the cylinder driving member 23 drives the crank 22 to drive the rotating shaft 21 to rotate, the counterweight fixing rod can rotate around the axis of the first connection hole 222 through the connecting member 42, so that the counterweight member 4 can maintain a vertical state to provide maximum stability and balance.

[0048] refer to Figure 3 As shown, in this embodiment, a protrusion 223 is provided on the crank 22 around the axis of the first connecting hole 222, and the corners of the end of the counterweight fixing shaft 41 can be slidably abutted against the inner side wall of the protrusion 223, and the inner side wall of the protrusion 223 provides friction resistance for the end of the counterweight fixing shaft 41. When the loading plate 3 is flipped to the two extreme positions of horizontal or vertical state, the protrusion 223 can limit the shaking of the counterweight 4, thereby improving the stability of the loading plate 3.

[0049] refer to Figure 2 As shown, the feeding device also includes an angle limiter, which is installed on the fixed bracket 1. When the feeding plate 3 is flipped between the two extreme positions of the horizontal state and the vertical state, the angle limiter can limit the swing of the counterweight 4, thereby further eliminating the possibility of the counterweight 4 shaking.

[0050] Specifically, in this embodiment, the angle limiter adopts a hydraulic buffer 5, and two hydraulic buffers 5 are installed on the fixed bracket 1 ( Figure 2 Only one of the hydraulic buffers 5 is shown in the figure, and the fixed end of one of the hydraulic buffers 5 is installed on a vertical beam 11 in the fixed bracket 1, and the telescopic rod of the hydraulic buffer 5 can be telescoped in the horizontal direction. When the loading plate 3 is flipped from the vertical state to the horizontal state, the telescopic rod of the hydraulic buffer 5 can move toward the direction close to the counterweight 4 and abut against the outer surface of the counterweight 4. The fixed end of the other hydraulic buffer 5 is installed on another vertical beam 11 in the fixed bracket 1, and the telescopic rod of the hydraulic buffer 5 can also be telescoped in the horizontal direction. When the loading plate 3 is flipped from the horizontal state to the vertical state, the telescopic rod of the hydraulic buffer 5 can move toward the direction close to the counterweight 4 and abut against the outer surface of the counterweight 4, so that the hydraulic buffer 5 can realize the angle limitation of the counterweight 4, offset the centrifugal force on the counterweight 4, and ensure the stability of the counterweight 4.

[0051] This embodiment also provides a material assembly machine, including the above-mentioned feeding device, assembly device and loading device. In the loading device, a counterweight 4 is arranged on the loading plate 3 at one end away from the feeding device, so that the torque at the position of the counterweight 4 on the loading plate 3 can be offset by the torque at the position of the receiving bin 32 on the loading plate 3. In this way, in the process of the loading plate 3 returning from a vertical state to a horizontal state, or from a horizontal state to a vertical state, the counterweight 4 can play a role in balancing the gravity torque, thereby reducing the shaking phenomenon of the loading plate 3, improving the stability of the loading process of the loading plate 3, effectively ensuring the loading efficiency of the entire loading device, and thus ensuring the effective operation of the entire material assembly machine.
