[0025] like Figure 1-4As shown, a spherical filler feeding mechanism of a preferred embodiment of the present invention includes a frame, two clamping assemblies symmetrically arranged on the frame, a driving mechanism and a unloading assembly, the clamping assembly includes a positioning mold arranged below the frame, the driving mechanism drives the two clamping assemblies to move relative to or away from each other to achieve positioning, clamping or resetting of the filler, and the unloading assembly is arranged on the frame corresponding to the clamping assembly, and is used to press the spherical filler on the clamping assembly into the next station.

[0026] The spherical filler feeding mechanism based on the above technical features is characterized by symmetrically arranging two clamping assemblies on the frame, the clamping assemblies including a positioning mold arranged under the frame, and a driving mechanism is arranged to drive the two clamping assemblies to move relative to or opposite to each other, so as to realize the positioning, clamping or resetting of the filler. When loading is required, the two clamping assemblies are opened, and the material is sent and placed between the two clamping assemblies to the correct position, and then the two clamping assemblies move relatively to realize the clamping of the material. After clamping the material, the feeding mechanism reaches the top of the closing mechanism under the action of external force, and the unloading assembly presses down the spherical filler on the clamping assembly, so that the spherical filler enters the closing mechanism, thereby realizing automatic feeding of the spherical filler and ensuring the feeding accuracy, so as to ensure that the closing mechanism of the next station can close the lid smoothly, thereby improving production efficiency.

[0027] In this embodiment, the frame includes a platform plate 18, and the two sides of the platform plate 18 are respectively provided with a left side plate 19 and a right side plate 20, and the rear end of the platform plate 18 is provided with a rear side plate 21, and the two ends of the rear side plate 21 are respectively connected to the left side plate 19 and the right side plate 20, and the outer wall of the rear side plate 21 is provided with a fixing seat, and the fixing seat is also a nut fixing seat, which can be conveniently applied to the automation equipment, and by controlling the lifting height, it can cooperate with other stations of the automation equipment. At the same time, in order to ensure the accuracy and stability of the up and down movement, the outer walls of the left side plate 19 and the right side plate 20 are provided with sliding blocks 22, and the sliding blocks 22 are installed in combination with the guide rails of the external support frame.

[0028] The inner wall of the left plate 19 or the right plate 20 is provided with a sensor 23 for detecting the position of the clamping assembly, and the platform plate 18 is provided with a sensing sheet corresponding to the sensor 23, and when the sensor 23 receives the signal of the sensing sheet, the movement of the clamping assembly is stopped, and the clamping assembly is at its initial position. That is, during clamping, the two clamping assemblies move relative to each other from the initial position to achieve clamping, and after clamping, they need to move back to the initial position (reset) to prepare for the next clamping.

[0029] In this embodiment, the clamping assembly includes a slide plate 1, and connecting plates 2 are provided at both ends of the slide plate 1. The connecting plates 2 are provided with a fixture avoidance opening, which can leave enough space for the fixture of the previous process to enter and exit without increasing the structure, making the structure compact, convenient and flexible. The other ends of the two connecting plates 2 are connected to the positioning mold 3, and the slide plate 1 is slidably connected to the platform plate 18.

[0030] Specifically, two guide rails 4 are arranged opposite to each other on the platform plate 18, and sliders 5 are arranged at both ends of the lower surface of the slide plate 1 in one-to-one correspondence with the guide rails 4, and the sliders 5 are slidably connected to the guide rails 4. At the same time, a nut fixing seat 6 is arranged on the upper surface of the slide plate 1, and a nut is arranged inside the nut fixing seat 6, and the two oppositely arranged nuts are internally threaded with a positive and negative thread ball screw 7, and one end of the positive and negative thread ball screw 7 is connected to the driving mechanism. When the clamping assembly needs to move, the driving mechanism is started to drive the positive and negative thread ball screw 7 to rotate, and under the action of the positive and negative thread ball screw 7 and the nut, the two clamping assemblies are moved relative to or away from each other.

[0031] In this embodiment, the driving mechanism includes a motor 8 fixed on the right side plate 20, a driving wheel 9 is provided on the output shaft of the motor 8, a driven wheel 10 is provided on the positive and negative thread ball screw 7, and a synchronous belt 11 is connected between the driving wheel 9 and the driven wheel 10. The inner wall of the right side plate 20 is provided with a motor fixing plate, and the motor 8 is arranged on the motor fixing plate. At the same time, a motor tensioning member is also provided on the right side plate 20, and a tensioning screw is provided on the motor tensioning member to tension the motor 8, thereby tensioning the synchronous belt, and the servo motor 8 drives the driving wheel 9 to transmit power to the positive and negative thread ball screw 7, thereby driving the two slide plates 1 to perform a closing and opening movement, which can accurately position the spherical material.

[0032] In addition, the left side plate 19 and the right side plate 20 are both provided with bearings, the two nut fixing seats 6 are arranged between the two bearings, and the positive and negative thread ball screws 7 are installed on the two bearings to achieve rotation. The motor 8 is a servo motor, which can control the position of the positioning mold with high precision and has strong stability.

[0033] In this embodiment, the positioning mold 3 includes a positioning plate, one side of which is provided with two arc-shaped clamping grooves, and the edge of the clamping groove is provided with an arc-shaped clamping plate 12 protruding downward, and the two clamping plates 12 arranged opposite to each other enclose a clamping hole for clamping the hemispherical filler 100. Therefore, after the two positioning plates are closed, two clamping holes are formed to clamp two hemispherical fillers 100 respectively. By providing the clamping plate 12 for clamping, the contact between the positioning plate and the buckling surface of the hemispherical material 100 is increased, the guiding distance is increased, the process of pushing the material is more stable, and the contact surface between the two positioning molds 3 and the next station is reduced, the chance of interference between the mechanisms is reduced, and the structure is more compact.

[0034] At the same time, since the guiding structure which is a perfect circle as a whole cannot ensure that the spherical material can enter it without damaging the material, in the present invention, the clamping hole is arranged to be spliced ​​with two arc-shaped (preferably semicircular) clamping grooves, which are formed into a perfect circle by controlling the distance. For the transfer of materials, this structure is flexible and convenient, and can fully ensure that the material can enter the guiding structure without damaging the material. At the same time, the material can be corrected from a non-perfect circle state to a state close to a perfect circle, which is beneficial to the subsequent process.

[0035] Specifically, during the process of pressing the spherical material by the positioning mold 3, the clamping force and deformation of the material can be controlled through the torque control performance of the servo motor, and the non-circular spherical material can be pressed into a nearly perfect circle, which is more conducive to the smooth advancement of the spherical material to the perfect circle station of the next process.

[0036] In this embodiment, the unloading assembly includes a cylinder 13 disposed on the platform plate 18 and a pressing plate 14 disposed below the platform plate 18, and the pressing plate 14 is disposed between the two clamping assemblies, and the telescopic rod of the cylinder 13 passes through the platform plate 18 to connect the pressing plate 14. When unloading is required, the cylinder 13 drives its telescopic rod to move downward, and the telescopic rod drives the pressing plate 14 to press downward, so that the filler is separated from the clamping assembly.

[0037] Specifically, since the spherical filler is composed of two hemispherical fillers 100, the pressing plate 14 includes two connected pressing plate bodies, each of which corresponds to a hemispherical filler 100. The telescopic rod of the cylinder 13 connects the middle parts of the two pressing plate bodies, and the connection position is clamped with a cylinder gasket to adjust the installation size. The outer side of the pressing plate body is provided with an avoidance groove 15 for avoiding the buckle on the hemispherical filler, so that the pressing plate 14 can avoid collision with the buckle during contact with the spherical material.

[0038] At the same time, in order to ensure the downward stability of the pressing plate body, a linear bearing 16 is provided on the platform plate 18 corresponding to each pressing plate body, and a guide rod 17 is inserted into the linear bearing 16, and the lower end of the guide rod 17 is connected to the corresponding pressing plate body. The cylinder 13 uses a stroke-adjustable cylinder, and the stroke can be adjusted according to the actual situation or error during debugging. The cylinder 13 drives the material pressing plate 14 downward to press the material downward into the next station.

[0039] The working process of the spherical filler provided by the present invention is:

[0040] (1) The two positioning dies 3 are opened and waiting for material to enter: The initial state of this mechanism is that the servo motor drives the two semicircular positioning dies 3 on the slide plate 1 to open to a specified distance through the synchronous belt 11 and the positive and negative tooth ball screw 7, leaving enough space for the material to enter.

[0041] (2) The two positioning molds 3 are opened and the material from the previous process is fed in: an avoidance opening is provided on the connecting plate 2 of the positioning mold 3, and the clamp of the previous process can clamp the material and enter the mechanism. The material is placed in the correct position, and the center of the circle of the hemispherical filler 100 is basically coincident with the center of the clamping hole after the two hemispherical positioning molds 3 are closed.

[0042] (3) The two positioning molds 3 are closed toward the middle to clamp the filler: the servo motor 8 rotates with high precision to drive the synchronous wheel 11 to transmit. When the positive and negative ball screws 7 rotate in one direction, the two nuts can be driven to move in the opposite direction, thereby driving the slide plate 1 to close and open. When the positioning mold 3 reaches the preset position, the spherical material is accurately positioned and clamped, and the fixture of the previous process withdraws from the avoidance opening of the positioning mold connecting plate.

[0043] (4) Pushing out the filler: The cylinder 13 on the top of the spherical filler is activated, driving the pressure plate 14 to move downward. The shape of the pressure plate 14 is consistent with the shape of the clamping holes of the two positioning molds 3, but it is slightly smaller in size and can pass through the positioning mold 3 without contact. Under the thrust of the pressure plate 14, the spherical filler moves downward along the circular wall surface of the positioning mold 3 and is accurately pushed out to the next station.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
