[0069] The technical solutions of the present application will be further described below by specific embodiments in conjunction with the drawings.

[0070] A workpiece feeding device 1, comprising: a receiving pipe 11, a first workpiece transfer plate 12, a second workpiece transfer plate 13, a workpiece impurity removal plate 14, a workpiece receiving shell 15 and a workpiece conveying assembly 16;

[0071] The five mechanisms of the receiving pipe 11, the first workpiece transfer plate 12, the second workpiece transfer plate 13, the workpiece impurity removal plate 14 and the workpiece receiving shell 15 are vertically distributed in sequence along the workpiece conveying direction, and the workpiece is placed in a processing station 01 when vertically transferred from the previous mechanism to a certain mechanism, and then horizontally adjusted and vertically transferred from a certain mechanism to the next mechanism; the output end of the workpiece conveying assembly 16 is connected to the workpiece receiving shell 15, for driving the workpiece receiving shell 15 to pass under the workpiece impurity removal plate 14 and receive the workpiece, and then driving the workpiece on the workpiece receiving shell 15 to output.

[0072] The present application provides a workpiece feeding device, by vertically distributing the five mechanisms of the receiving pipe 11, the first workpiece transfer plate 12, the second workpiece transfer plate 13, the workpiece impurity removal plate 14 and the workpiece receiving shell 15 in sequence, the workpiece can pass through the processing station 01 of each mechanism during transfer, so that processing can be performed in each processing station 01, and pre-processing can be completed during transfer, thereby shortening the actual processing time of the workpiece and solving the problem of longer processing time caused by the need to transfer and then process the workpiece.

[0073] As Figure 10The first workpiece transfer plate 12, the second workpiece transfer plate 13, the workpiece impurity removal plate 14 and the workpiece receiving shell 15 are vertically distributed in sequence, and can be partially vertically integrated or partially separated to form gaps. Figure 3 The processing station 01 is an oil removal channel 011, which is connected to an air extraction device. The air extraction device extracts the airflow of the oil removal channel 011, so that the airflow flows from top to bottom through the surface of the workpiece. The machining oil on the surface of the workpiece falls into the oil removal channel 011 and is separated from the surface of the workpiece along with the flow of the airflow, thereby realizing the impurity removal treatment of the workpiece. Figure 10 The processing station 01 is provided with an inner cavity detection and recognition device 012, which can irradiate the inner cavity of the workpiece by laser to determine whether the inner cavity of the workpiece is completed or the inner cavity of the workpiece is processed completely. The processing station 01 can be any station known in the art that has the functions of machining, detecting, impurity removal, etc. When the workpiece is machined in the processing station 01, it can be horizontally adjusted by the driving of the mechanism to transfer to the next mechanism and repeat the above steps. In this way, the workpiece can pass through one or more processing stations 01 during the transfer process to be machined in a certain processing station 01 as needed, thereby realizing simple machining and processing during the transfer process and further shortening the machining time of the workpiece in the workpiece machining device 2.

[0074] The vertical movement and horizontal movement of adjacent mechanisms in the five mechanisms of the receiving pipe 11, the first workpiece transfer plate 12, the second workpiece transfer plate 13, the workpiece impurity removal plate 14 and the workpiece receiving shell 15 can be realized by a known linear drive mechanism 8, such as a cylinder, a moving trolley, a combination of a motor and a lead screw, or a conveyor belt structure, etc. Preferably, the vertical movement of adjacent mechanisms can be realized by gravity to omit the driving mechanism for vertical transfer.

[0075] Preferably, it further comprises a feeding base 10.

[0076] The receiving tube 11 is installed on the feeding base 10, and the receiving tube 11, the first workpiece transfer plate 12, the second workpiece transfer plate 13 and the workpiece impurity removal plate 14 are stacked from top to bottom; the first workpiece transfer plate 12 and the second workpiece transfer plate 13 are independently movable; the first workpiece transfer plate 12 is provided with a first feeding channel 121, the second workpiece transfer plate 13 is provided with a second feeding channel 131, and the workpiece impurity removal plate 14 is provided with the processing station 01 at one end of the second workpiece transfer plate 13, and is provided with a workpiece feeding channel 141 at the other end;

[0077] The input end of the first feeding channel 121 is vertically aligned with the output end of the receiving tube 11; after the first workpiece transfer plate 12 moves, the first feeding channel 121 is moved to be aligned with the second feeding channel 131, so that the first feeding channel 121, the second feeding channel 131 and the processing station 01 are vertically aligned;

[0078] The output end of the second feeding channel 131 is aligned with the opening of the impurity removal tube; after the second workpiece transfer plate 13 moves, the second feeding channel 131 is moved to be aligned with the input end of the workpiece feeding channel 141;

[0079] The output end of the workpiece conveying assembly 16 is connected to the workpiece receiving shell 15, which is used to drive the workpiece receiving shell 15 to pass below the output end of the workpiece feeding channel 141 and receive the workpiece, and then drive the workpiece receiving shell 15 to output the workpiece.

[0080] As Figure 3 In one embodiment, the receiving tube 11, the feeding base 10, the first workpiece transfer plate 12, the second workpiece transfer plate 13 and the workpiece impurity removal plate 14 are sequentially distributed; this embodiment has one processing station 01; after the workpiece falls from the upper end of the receiving tube 11, it will be in contact with the first feeding channel 121 of the first workpiece transfer plate 12 under the action of gravity, and the bottom surface of the workpiece is in contact with the upper surface of the second workpiece transfer plate 13, that is, the workpiece is transferred from the receiving tube 11 to the first workpiece transfer plate 12; then, the first workpiece transfer plate 12 moves horizontally, driving the workpiece in the first feeding channel 121 to move, and finally when the first feeding channel 121 is aligned with the input end of the second feeding channel 131, the workpiece is transferred to the second feeding channel 131 under the action of gravity and is in contact with the bottom of the processing station 01; after the workpiece is processed (such as Figure 3For oil removal treatment, the second workpiece transfer plate 13 moves horizontally, driving the workpiece in the second feeding channel 131 to align with the workpiece feeding channel 141. The workpiece passes through the workpiece feeding channel 141 under the action of gravity and finally falls to the workpiece receiving shell 15 below. The workpiece conveying assembly 16 is started, driving the workpiece receiving shell 15 to move to the receiving end of the workpiece processing device 2, so as to realize the conveying of the workpiece to the workpiece processing device 2.

[0081] The workpiece conveying assembly 16 can be a mechanism with a driving moving function, such as a moving trolley, a conveying belt, a combination of a conveying gear and a conveying rack, etc. At the same time, in order to realize the horizontal movement of the first workpiece transfer plate 12 and the second workpiece transfer plate 13, manual driving or a known mechanical driving mode can be used. The mechanical driving embodiment can select a linear driving mechanism 8, which is preferably a cylinder. The fixed end of the cylinder is installed on the feeding base 10. When the output end of the cylinder is stretched, it drives the first workpiece transfer plate 12 or the second workpiece transfer plate 13 to move. When the output end of the cylinder is retracted, it drives the first workpiece transfer plate 12 or the second workpiece transfer plate 13 to reset.

[0082] More preferably, it further comprises a third transfer plate 17 and a transfer bottom plate 18.

[0083] The third transfer plate 17 is provided with a third feeding channel 171, and the transfer bottom plate 18 is provided with a bottom plate feeding channel 181. The third transfer plate 17 moves on the surface of the transfer bottom plate 18 and is resettable. In one of the moving positions, the third feeding channel 171 is vertically aligned with the output end of the workpiece feeding channel 141. In another moving position, the third feeding channel 171 is vertically aligned with the input end of the bottom plate feeding channel 181. The opening of the workpiece receiving shell 15 moves through the lower side of the output end of the bottom plate feeding channel 181.

[0084] Based on the above embodiment, the third transfer plate 17 is arranged below the workpiece impurity removal plate 14; the third transfer plate 17 is provided with a third feeding channel 171; when the third transfer plate 17 is reset and moves on the transfer bottom plate 18, the third transfer plate 17 can move the third feeding channel 171 and the non-third feeding channel area to be aligned with the workpiece feeding channel 141 respectively during the movement, and can also move the third feeding channel 171 and the non-third feeding channel area to be aligned with the bottom plate feeding channel 181 of the transfer bottom plate 18 respectively; in this structure, the workpiece falls from the workpiece feeding channel 141 to the third transfer plate 17, and the workpiece can still be located in the workpiece feeding channel 141, and the bottom of the workpiece abuts against the non-third feeding channel area on the surface of the third transfer plate 17; then, the third transfer plate 17 moves, and the workpiece feeding channel 141 gradually approaches the third feeding channel 171, and finally the third feeding channel 171 transfers the workpiece when the workpiece feeding channel 141 is aligned; the workpiece is placed in the third feeding channel 171, and the bottom of the workpiece contacts the surface of the transfer bottom plate 18; when the third transfer plate 17 is reset, the third feeding channel 171 can be moved to be aligned with the bottom plate feeding channel 181, and the workpiece can be driven to enter the bottom plate feeding channel 181, and finally the workpiece can pass through the bottom plate feeding channel 181 to enter the workpiece receiving shell 15; in this structure, the workpiece first abuts against the non-third feeding channel area, then passes through the third feeding channel 171 to enter the transfer bottom plate 18, and then is transferred from the transfer bottom plate 18 to the workpiece receiving shell 15, which can avoid the problem that the workpiece and the workpiece receiving shell 15 are easily deformed due to the direct falling of the workpiece, and improves the stability of workpiece feeding and the appearance integrity of the workpiece.

[0085] The resettable movement of the third transfer plate 17 on the surface of the transfer bottom plate 18 can be realized by a linear driving mechanism 8 known to have a driving movement function, such as a cylinder, a moving trolley, a combination of a motor and a lead screw, or a conveyor belt structure, etc.

[0086] Further optimization, the workpiece conveying assembly 16 comprises a conveying frame 161, a conveying rotating wheel 162, a conveying synchronous belt 163 and a conveying driver 164.

[0087] The conveying rotating wheels 162 are respectively installed on the conveying frame 161; the conveying synchronous belt 163 is connected in a synchronous rotation manner, and the workpiece receiving shells 15 are respectively arranged at different positions of the conveying synchronous belt 163; the output end of the conveying driver 164 is connected to one of the conveying rotating wheels 162, for driving the conveying rotating wheels 162 to rotate, and driving the workpiece receiving shells 15 of the conveying synchronous belt 163 to move.

[0088] As Figure 2The transmission rotating wheel 162 can be arranged at different positions of the transmission frame 161, and the number of the transmission rotating wheels 162 can be multiple. When the transmission driving device 164 drives the transmission rotating wheel 162 to rotate, the transmission synchronous belt 163 rotates under the tension of the other transmission rotating wheels 162, thereby driving the workpiece receiving shell 15 to rotate, so as to drive the workpiece receiving shell 15 at different positions. Since the transmission synchronous belt 163 is in a ring structure, the trajectory when rotating is circular, so that the workpiece receiving shell 15 can be continuously transmitted to the output end of the bottom plate feeding channel 181 (one embodiment) or the output end of the workpiece feeding channel 141 (one embodiment).

[0089] Meanwhile, the transmission rotating wheel 162 is in a wheel structure; in one embodiment, the transmission rotating wheel 162 can be a common moving wheel, and the transmission synchronous belt 163 can be a common synchronous belt, and the moving wheel tightens the synchronous belt; in one embodiment, the transmission rotating wheel 162 is a gear, and the transmission synchronous belt 163 can be a toothed chain belt, and the gear meshes with the toothed chain belt.

[0094] The workpiece processing system provided by the scheme can transfer the workpiece from the workpiece feeding device 1 to the workpiece processing device 2, and transfer the workpiece to different processing areas 03 of the workpiece processing device 2 under the driving action of the workpiece transfer device 3. The workpiece can be processed during the workpiece feeding and after the workpiece feeding through the processing station 01 of the workpiece feeding device 1 and the processing area 03 of the workpiece processing device 2, so that the processing steps of the workpiece can be performed synchronously during and after the workpiece feeding, the processing time of the workpiece is effectively shortened, the time during the transfer of the workpiece to the workpiece processing device 2 is maximized, the processing efficiency is improved, and the problem of long processing time caused by the processing of the workpiece in the workpiece processing device 2 in the prior art is solved.

[0095] More preferably, the workpiece processing device 2 is provided with a processing receiving tube 02 at one of the processing areas 03; the upper end of the processing receiving tube 02 is connected to the output end of a funnel structure 021, the input end of the funnel structure 021 is used to receive the workpiece output by the workpiece receiving shell 15; the input end of the funnel structure 021 is aligned with the conveying rotating wheel 162 at the end of the workpiece stroke, the conveying rotating wheel 162 drives the workpiece receiving shell 15 to angularly flip through the conveying synchronous belt 163, so that the opening of the workpiece receiving shell 15 is downwardly directed to the input end of the funnel structure 021; the lower end of the processing receiving tube 02 is communicated with the processing area 03.

[0096] As Figure 2 and Figure 4 , the two ends of the processing receiving tube 02 are formed with a height difference, the upper end of the processing receiving tube 02 is used to receive the workpiece output by the workpiece receiving shell 15, and the lower end of the processing receiving tube 02 can be aligned with the processing area 03; after the workpiece enters the upper end of the processing receiving tube 02, it can fall to the processing area 03 by gravity, or the workpiece can be blown to the processing area 03 by a certain airflow; at the same time, the workpiece receiving shell 15 of the present scheme is driven to angularly flip by the conveying rotating wheel 162 at the end of the workpiece conveying path; specifically, when the conveying synchronous belt 163 passes through the conveying rotating wheel 162 at the end of the workpiece conveying path, a section of the conveying synchronous belt 163 passes through the outside of the conveying rotating wheel 162, and the angle of the section is greater than 90°, so that when the conveying synchronous belt 163 passes through the conveying rotating wheel 162, the workpiece receiving shell 15 is synchronously flipped by an angle greater than 90°, for example, 180°, under the driving action of the conveying synchronous belt 163, so that the workpiece of the workpiece receiving shell 15 can be poured into the funnel structure 021; the workpiece enters the funnel structure 021 from the large-diameter end, the inner diameter of the funnel structure 021 gradually narrows to gradually input the workpiece into the input end of the processing receiving tube 02, and finally output from the output end of the processing receiving tube 02 to the processing area 03.
