Description

Technical Field

[0001] This application relates to the field of spring production equipment, and particularly to a material receiving device for a spring machine. Background Art

[0002] A spring machine is a mechanical device used for manufacturing springs. It generally consists of a feeding mechanism, a forming mechanism, a cutting mechanism, a control system, etc. The spring machine can automatically complete processes such as feeding, forming, and cutting of springs according to preset parameters, thereby producing spring products that meet requirements.

[0003] For example, a camless numerical control spring machine with the publication number CN216226706U includes a machine case, a panel, a tool holder assembly, a control box, a lighting lamp, a feeding mechanism, a straightening mechanism, a winding column, a wire feeding mechanism, and a wire outlet. The feeding mechanism feeds the spring wire for making springs into the straightening mechanism. The straightening mechanism straightens the spring wire and then feeds it into the winding column. The spring wire enters the wire feeding mechanism through the winding column. The wire feeding mechanism feeds the spring wire into the wire outlet on the panel. Eight groups of tool holder assemblies in different directions are arranged on the panel, and each group of tool holder assemblies is controlled by a separate servo motor. The spring wire sent out from the wire outlet is processed into a spring by the eight groups of tool holder assemblies in different directions arranged on the panel. The processed spring will automatically fall into the material receiving box on the machine case.

[0004] In the above solution, the produced springs will automatically fall into the material receiving box for collection. However, for some special-shaped springs, after being collected by the above material receiving box, they still need to be sorted and then packed, resulting in low material receiving efficiency. Summary of the Utility Model

[0005] In order to improve the material receiving efficiency of springs, this application provides a material receiving device for a spring machine.

[0006] A material receiving device for a spring machine provided in this application adopts the following technical solution: A material receiving device for a spring machine includes a material placing rack, a controller, and a manipulator, which are arranged on one side below the spring machine. The controller is electrically connected to the spring machine and the manipulator at the same time. The controller is used to receive the clamping signal of the spring machine to send out a control signal. The manipulator responds to the control signal of the controller, drives the manipulator to clamp the spring formed by the spring machine, and then arranges and places it on the material placing rack.

[0007] By adopting the above technical solution, before the spring forming machine cuts the formed spring, it sends a clamping signal to the controller. The controller issues a control signal to the manipulator based on the clamping signal of the spring forming machine, driving the manipulator to clamp one end of the spring. At the same time, the spring forming machine cuts the spring, and the manipulator clamps the spring and arranges it on the discharging rack, and then can directly collect and pack the springs neatly arranged on the discharging rack, thus improving the spring receiving efficiency.

[0008] Preferably, the manipulator includes a base, a robotic arm, and a clamping assembly. The robotic arm is installed on the base, the clamping assembly is installed at the end of the robotic arm, and the base is arranged on one side of the discharging rack.

[0009] By adopting the above technical solution, the robotic arm drives the clamping assembly to move and switch between the clamping station and the discharging station, and then the clamping assembly clamps the spring at the clamping station and places it on the discharging station, thus reducing the labor cost.

[0010] Preferably, the clamping assembly includes a jaw cylinder and two symmetric clamping blocks arranged on the jaw cylinder.

[0011] By adopting the above technical solution, the jaw cylinder drives the two clamping blocks to stably clamp the spring.

[0012] Preferably, soft pads are arranged on the opposite side walls of the clamping blocks.

[0013] By adopting the above technical solution, the soft pads arranged on the clamping blocks can reduce the damage or deformation of the spring during the clamping process.

[0014] Preferably, the clamping blocks are made of bakelite material.

[0015] By adopting the above technical solution, the clamping blocks made of bakelite material can play an insulating role, thus reducing the static electricity on the spring forming machine from being conducted to the manipulator through the spring and affecting the stability of the manipulator.

[0016] Preferably, the discharging rack includes a rack body and discharging square rods. The discharging square rods are arranged above the rack body and are used to receive and place the springs.

[0017] By adopting the above technical solution, the manipulator clamps the spring and places it on the discharging square rods on the discharging rack, thus facilitating collection and packing.

[0018] Preferably, a pushing groove is opened along the length direction on the upper surface of the discharging square rod. The clamping blocks are square blocks. The controller drives the manipulator to clamp the spring and place it at the discharging station of the discharging square rod, and then drives one end corner of the clamping block to push the spring to one side along the pushing groove.

[0019] By adopting the above technical solution, the controller drives the manipulator to place the clamped spring at the feeding station of the feeding square rod, and then drives the manipulator to drive one end corner of the clamping block to push the spring along the feeding groove to one side of the feeding square, so as to facilitate the subsequent placement of the spring at the feeding station, and gradually arrange and place the springs at the feeding station.

[0020] Preferably, two feeding square rods are provided, and the two feeding square rods are arranged on the frame at intervals.

[0021] By adopting the above technical solution, setting two feeding square rods enables the springs to be placed on the other feeding square rod when one of the feeding square rods is being collected and processed, thereby improving the material collection efficiency.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] Before the spring machine forms and cuts the spring, it sends a clamping signal to the controller. The controller issues a control signal to the manipulator based on the clamping signal of the spring machine, driving the manipulator to clamp one end of the spring. At the same time, the spring machine cuts the spring, and the manipulator clamps the spring and arranges it on the feeding rack, and then can directly collect and pack the neatly arranged springs on the feeding rack, thereby improving the material collection efficiency of the spring and reducing the labor cost.

[0029] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0030] The embodiment of the present application discloses a material collection device for a spring machine. Refer to Figure 1 and Figure 2, the spring machine 1 in this application is used to produce special-shaped springs 2. The special-shaped springs 2 in this application are strip-shaped and have a bent and sunken part in the middle position. The material receiving device is used to clamp, move and arrange the special-shaped springs 2 formed by the spring machine 1, so as to facilitate subsequent collection and packing. Specifically, the material receiving device includes a feeding rack 3, a controller 4 and a manipulator 5. The feeding rack 3 is arranged on one side below the spring machine 1. The controller 4 is electrically connected to the spring machine 1 and the manipulator 5 at the same time. The controller 4 is used to receive the clamping signal of the spring machine 1 to send a control signal. The manipulator 5 responds to the control signal of the controller 4, drives the manipulator 5 to clamp the spring formed on the spring machine 1, and then arranges and places it on the feeding rack 3. In this application, the clamping signal is sent when the spring in the spring machine 1 is in the state to be cut after being formed. When the controller 4 controls the manipulator 5 to clamp one end of the special-shaped spring 2, the cutting mechanism on the spring machine 1 synchronously cuts. Then the manipulator 5 clamps the special-shaped spring 2 and arranges and places it on the feeding rack 3, so as to facilitate the subsequent collection and packing of the special-shaped spring 2, thereby improving the material receiving efficiency of the spring and reducing the labor cost.

[0031] Referring to Figure 3 , the manipulator 5 includes a base 51, a robotic arm 52 and a clamping assembly 53. The robotic arm 52 is installed on the base 51, and the clamping assembly 53 is installed at the end of the robotic arm 52. The base 51 is arranged on one side of the feeding rack 3. The robotic arm 52 in this application adopts a three-dimensional robotic arm 52, which can move in a three-dimensional space and is controlled by a program set in the controller 4 to move between the clamping station and the feeding station. The controller 4 in this application is a PLC control cabinet, and the base 51 is installed on the upper surface of the PLC control cabinet.

[0032] Specifically, the clamping assembly 53 includes a jaw cylinder 531 and two symmetrical clamping blocks 532 arranged on the jaw cylinder 531. The clamping blocks 532 in this application are square blocks. Soft pads 533 are arranged on the opposite side walls of the clamping blocks 532. By arranging the soft pads 533 on the clamping blocks 532, the loss or deformation of the spring during the clamping process can be reduced. And in order to improve the stability of the manipulator 5, the clamping blocks 532 are made of bakelite material. The clamping blocks 532 made of bakelite material can play an insulating role, thereby reducing the static electricity on the spring machine 1 from being conducted to the manipulator 5 through the special-shaped spring 2 and affecting the stability of the manipulator 5.

[0033] Referring to Figure 4 , the feeding rack 3 includes a rack body 31 and a feeding square rod 32. The feeding square rod 32 is horizontally arranged above the rack body 31 and is used to receive and place the special-shaped spring 2. The width of the feeding square rod 32 is adapted to the width of the bent and sunken part in the middle of the special-shaped spring 2.

[0034] Referring to Figure 3 and Figure 4, a pushing groove 321 is formed on the upper surface of the material discharging square rod 32 along the length direction. The controller 4 drives the manipulator 5 to clamp the spring and place it at the material discharging station of the material discharging square rod 32, and then drives the clamping block 532 to rotate, so that one end corner of the clamping block 532 pushes the special-shaped spring 2 to one side along the pushing groove 321, thereby arranging the special-shaped springs 2 neatly on the material discharging square rod 32 in sequence. In order to improve the material receiving efficiency of the special-shaped spring 2, two material discharging square rods 32 are provided in this application, and the two material discharging square rods 32 are arranged at intervals on the frame body 31. Setting two material discharging square rods 32 enables the special-shaped spring 2 to be placed on the other material discharging square rod 32 when one of the material discharging square rods 32 is being collected and processed.

[0035] The implementation principle of the material receiving device of a spring machine in an embodiment of this application is as follows: After the special-shaped spring 2 is formed by the spring machine 1, the spring machine 1 sends a clamping signal to the controller 4. After receiving the clamping signal from the spring machine 1, the controller 4 issues a control signal to control the manipulator 5 to move to the clamping station at the spring machine 1 to clamp one end of the formed special-shaped spring 2. At the same time, the spring machine 1 cuts off the other end of the special-shaped spring 2. Then the controller 4 continues to control the manipulator 5 to move to the material discharging station at the material discharging rack 3, places the concave part of the special-shaped spring 2 on the upper surface of the material discharging square rod 32, and then drives the clamping block 532 on the clamping assembly 53 to rotate, so that one end corner of the clamping block 532 pushes the special-shaped spring 2 to one side along the pushing groove 321, thereby arranging the special-shaped springs 2 neatly on the material discharging square rod 32 in sequence according to the above clamping actions, thereby improving the material receiving efficiency of the special-shaped spring 2 and reducing the labor cost.

[0036] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
