[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following examples are provided to further illustrate this application in detail.

[0053] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0054] like Figure 1 As shown, the second strip b has been pre-cut with supports a1 at regular intervals, and multiple guide holes b1 are pre-formed on the second strip b at set intervals. The guide holes b1 are used to engage with the guide pins of the positioning mechanism, preventing the second strip b from moving during processing. During the conveying process of the second strip b, after each conveying cycle, other processing mechanisms at their respective stations can perform cutting, welding, riveting, and assembly processes on the second strip b, thereby processing it into a contact assembly. Figure 1 The final contact assembly a can be seen to include a bracket a1, a moving contact a2, a trip bolt a3, and two shafts a4 mounted thereon. The moving contact a2 is welded to one end of the bracket a1, one shaft a4 is used to hinge the bracket a1 to the trip bolt a3, and the other shaft a4 is used to limit the range of rotation of the bracket a1.

[0055] Continue to refer to Figure 1 The first material strip c has been pre-cut at regular intervals to form tripping bolts a3. During the conveying of the second material strip b, the parts supply system of this embodiment is used to sequentially cut the tripping bolts a3 from the first material strip c and move them to preset positions on the second material strip b, in preparation for connecting the tripping bolts a3 to the bracket on the second material strip b. It should be noted that although this embodiment is described using the task of connecting the tripping bolts a3 to the bracket a1 to form a contact assembly as an example, the actual use of this parts supply system is not limited to this. For example, the tripping bolts a3 can also be other parts, and the bracket a1 can also be other components for the production and installation of other components.

[0056] Reference Figure 2The part feeding system of the embodiment comprises a first conveying device 11 and a punching and transferring integrated machine 1. The first conveying device 11 is used for conveying the first material belt c. The punching and transferring integrated machine 1 can punch the parts conveyed by the first conveying device 11 in sequence, and the material pushing mechanism 130 of the punching and transferring integrated machine 1 is arranged to gradually push the parts falling from the material falling port to the predetermined position connectable with the elements on the second material belt b. The second material belt b is conveyed by the second conveying device 14 in a direction parallel to the first material belt c, and the second conveying device 14 is arranged at the end of the material guide track 13 of the punching and transferring integrated machine 1. It should be noted that, for the sake of simplicity, the whole second conveying device 14 is not shown in Figure 2 the specific implementation, the main structure of the second conveying device 14 can refer to the first conveying device 11.

[0057] As shown in Figure 3 , the related mechanism for realizing the material pulling function of the first conveying device 11 can comprise a first material clamping mechanism 1141, a second material clamping mechanism 1142 and a material pulling mechanism. The first material clamping mechanism 1141 and the second material clamping mechanism 1142 are arranged in the same line with the plurality of material walking tracks 116, and are respectively used for clamping and releasing the material belt, and the first material clamping mechanism 1141 is fixedly arranged relative to the machine table. At the same time, the material pulling mechanism is used for driving the second material clamping mechanism 1142 to move along the material walking track 116. The material pulling mechanism and the first material clamping mechanism 1141 can be fixedly arranged on the machine table through a plurality of supports 112.

[0058] Preferably, in the first conveying device 11, two material guide plates 111 can be connected at the material inlet end and the material outlet end of the material walking track 116, and the material guide plate 111 is provided with an arc-shaped guide groove 1111 curved from the horizontal direction to the vertical direction, so that the material belt can naturally sag along the arc-shaped guide groove 1111 on the material inlet side and the material outlet side without the support of the material walking track 116, and the material belt will not be damaged.

[0059] Exemplarily, the first material clamping mechanism 1141, the second material clamping mechanism 1142 and the material pulling mechanism can be cooperatively controlled by a controller. For example, the controller can be signal-connected with the first material clamping mechanism 1141, the second material clamping mechanism 1142 and the material pulling mechanism, and the controller is configured to: first control the first material clamping mechanism 1141 to release the material belt and the second material clamping mechanism 1142 to clamp the material belt, and then control the material pulling mechanism to act to make the second material clamping mechanism 1142 drive the material belt to move forward by a first distance (L1) and then stop. Figure 2When the material tape moves forward by a first distance, the first material clamping mechanism 1141 clamps the material tape, and the second material clamping mechanism 1142 releases the material tape, and then the pulling mechanism is controlled to move backward by a first distance, so as to prepare for the next pulling process.

[0060] In combination Figure 3 In a preferred embodiment, the first material clamping mechanism 1141 and the second material clamping mechanism 1142 can each include a frame 1151, a fixed clamping piece 1152, a movable clamping piece 1154, and a first driving device 1344. The fixed clamping piece 1152 is arranged at one end of the frame 1151 and is used to support the material tape. The movable clamping piece 1154 is arranged opposite to the fixed clamping piece 1152 and is driven by the first driving device 1344 to move towards or away from the fixed clamping piece 1152. Thus, when the first driving device 1344 drives the movable clamping piece 1154 to move towards the fixed clamping piece 1152, the movable clamping piece 1154 can press the material tape supported on the fixed clamping piece 1152. When the first driving device 1344 drives the movable clamping piece 1154 to move away from the fixed clamping piece 1152, the movable clamping piece 1154 can release the material tape supported on the fixed clamping piece 1152. For example, the fixed clamping piece 1152 or the movable clamping piece 1154 can be in the shape of a plate, a wedge, a column, etc. Preferably, one side of the fixed clamping piece 1152 or the movable clamping piece 1154 facing the material tape is a flat surface consistent with the width of the material tape.

[0061] Continuing to refer to Figure 3 Since the multi-segment material tape track 116 needs to meet the requirement of supporting the material tape, and meet the requirement of the moving space of the second material clamping mechanism 1142. In a preferred embodiment, the frame 1151 of the first material clamping mechanism 1141 can be provided with a segment of material tape track 116 on each side, and the frame 1151 of the second material clamping mechanism 1142 can be provided with a segment of material tape track 116 on one side. When the pulling mechanism moves backward by a first distance, the material tape track 116 between the second material clamping mechanism 1142 and the first material clamping mechanism 1141 is connected, and the second material clamping mechanism 1142 is separated from the adjacent material tape track 116 on the other side by a first distance. In this way, the reliability of the first conveying device 11 in conveying the material tape can be maintained while meeting the requirement of the moving space of the second material clamping mechanism 1142.

[0062] Referring to Figure 4The first driving device 1344 can include a first cylinder 1153, a first electromagnetic valve group, and a first magnetic switch. The first cylinder 1153 is arranged at the other end of the frame 1151, and has a cylinder barrel that is non-magnetic and a piston that is non-magnetic, and a permanent magnet ring is arranged on the piston. The first electromagnetic valve group is connected to the gas circuit of the first cylinder 1153 and controls the movement of the piston. The first magnetic switch is arranged outside the cylinder barrel and is configured to be turned on when the piston drives the movable clamp 1154 to move to a position for clamping the material belt.

[0063] In a preferred embodiment, the controller is further connected to the first electromagnetic valve group and the first magnetic switch of the first material clamping mechanism 1141 and the second material clamping mechanism 1142, and is configured to: control the first electromagnetic valve group to move the movable clamp 1154 towards and away from the fixed clamp 1152; and when the controller receives a signal from the first magnetic switch that is turned on from off, control the first electromagnetic valve group to stop moving the movable clamp 1154.

[0064] Thus, the first material clamping mechanism 1141 and the second material clamping mechanism 1142 can control the gas circuit of the first cylinder 1153 by controlling the electromagnetic valve group of the controller, and determine the moving direction of the piston. For example, the piston can move from the initial position to the position where the first magnetic switch is turned on, and the controller determines that the first material clamping mechanism 1141 or the second material clamping mechanism 1142 has clamped the material belt. In addition, when the first material clamping mechanism 1141 or the second material clamping mechanism 1142 releases the material belt, the piston can be returned to the initial position.

[0065] Preferably, when the controller does not receive a signal from the first magnetic switch that is turned on from off within a set time period, an alarm signal is sent. This embodiment is for detecting the failure of the first material clamping mechanism 1141 or the second material clamping mechanism 1142 to clamp the material belt normally, to ensure that the person in charge is notified in time to troubleshoot the failure.

[0066] It should be noted that although the first driving device 1344 is described by taking the first cylinder 1153 as an example in this embodiment, the above functions of the first material clamping mechanism 1141 or the second material clamping mechanism 1142 can still be achieved by motor driving.

[0067] Continuing to refer to Figure 3In an alternative embodiment, the pulling mechanism includes a sliding rail 1131, a moving member 1133 and a second driving mechanism. The sliding rail 1131 is arranged on the machine and extends along the feeding track 116, the moving member 1133 is slidingly arranged on the sliding rail 1131, and the second clamping mechanism 1142 is arranged on the moving member 1133. For example, the moving member 1133 can be provided with limiting strips on both sides, and the inner walls of the sliding rail 1131 can form limiting grooves, so that the moving member 1133 can be slidingly matched with the sliding rail 1131. For another example, there can be a sliding block 1331 slidingly arranged in the sliding rail 1131, and the moving member 1133 is connected to the sliding block 1331 to realize the sliding connection of the moving member 1133 relative to the sliding rail 1131. The controller is signal connected with the second driving mechanism. The controller can control the second driving mechanism to drive the moving member 1133 to move along the sliding rail 1131, so that the second clamping mechanism 1142 can pull the material belt to move forward by a first distance.

[0068] With reference to the foregoing Figure 3 The second driving mechanism described above can include a pulling motor 113, a lead screw shaft 1132 and at least one photoelectric switch. The lead screw shaft 1132 is rotatably arranged on the sliding rail 1131, one end of the lead screw shaft 1132 is connected to the output end of the pulling motor 113, and the lead screw shaft 1132 also drives the moving member 1133 to move through threaded transmission. For example, both ends of the lead screw shaft 1132 can be arranged on the track through a bearing respectively, so that the lead screw shaft 1132 realizes rotatable connection with the sliding rail 1131. The photoelectric switch can be arranged on the machine and set to be turned on when the moving member 1133 moves forward by a first distance.

[0069] For example, the first conveying device 11 can know from the pre-test that the pulling mechanism driving the second clamping mechanism 1142 to move forward or backward by a first distance requires a pulse. For example, when the pulling motor 113 is a stepper motor, the number of pulses can be controlled to control the rotation angle; when the pulling motor 113 is a servo motor, the length of the pulse time can be controlled to control the rotation angle. In this way, the moving distance of the pulling mechanism driving the second clamping mechanism 1142 is controlled.

[0070] Preferably, the controller can be connected with the pulling motor 113 through the photoelectric switch signal, and the controller is further configured to control the rotation angle of the pulling motor 113 by controlling the number or time of pulses sent to the pulling motor 113, so as to drive the second clamping mechanism 1142 to advance or retreat. The pulling motor 113 is controlled to stop when receiving the feedback signal from the photoelectric switch that the signal is switched from off to on. According to the embodiment, in an ideal case, the pulling motor 113 can make the pulling mechanism complete the task of driving the second clamping mechanism 1142 to advance a first distance or retreat a first distance according to the set pulse parameters, and the photoelectric switch can send the feedback signal to the controller at this time. In addition, the photoelectric switch can also be used to correct the precision problem of the pulling motor 113 "out of step" after the second driving mechanism operates for a period of time, so as to ensure the accuracy and reliability of the first conveying device 11 in conveying the material belt.

[0071] It should be noted that although the above embodiment is described by taking the second driving mechanism containing the pulling motor 113 as an example, the second driving mechanism can also take a pneumatic cylinder as a power device to realize the above functions of the pulling mechanism.

[0072] With reference to Figure 2 and Figure 4 The punching and transferring integrated machine 1 comprises a machine base 121, and the machine base 121 is provided with a punching mechanism 12, a guide rail 13 and a pushing mechanism 130. The punching mechanism 12 is used for cutting off the parts on the first material belt c passing through the punching mechanism 12, and has a dropping port for the cut-off parts to drop, and the lower part of the punching mechanism 12 further forms an installation space in communication with the dropping port. One end of the guide rail 13 is located in the installation space, and the other end extends from one side of the punching mechanism 12, and the extension direction is perpendicular to the length direction of the first material belt c in space. The pushing mechanism 130 is arranged to push the parts dropped from the dropping port to the guide rail 13, and push the parts on the guide rail 13 to a predetermined position.

[0073] In the punching and transferring integrated machine 1 provided in the embodiment, when the first material belt c is conveyed to a position where a part of the first material belt c is located at the dropping port of the punching mechanism 12, the punching mechanism 12 works to cut off the part from the first material belt c, and the pushing mechanism 130 can push the cut-off part to a predetermined position by means of the guide rail 13. The punching and transferring integrated machine 1 can take the tripping pin a3 as the part, and continuously push the tripping pin a3 to the predetermined position connectable with the support a1 on the second material belt b, so as to prepare for connecting the tripping pin a3 to the support a1 on the second material belt b. In this way, the automation and production efficiency of the assembly process of the low-pressure air switch can be improved.

[0074] With reference to Figure 4The punching mechanism 12 can include a driving cylinder 125, an upper die set 123, a lower die set 122, and a plurality of guide columns 124. The driving cylinder 125 can be arranged on the top of the base 121 and the moving end thereof faces downward. For example, at least one magnetic switch can be arranged on the driving cylinder 125 to determine that the piston and the upper die set 123 have moved to the preset position by cooperating with the permanent magnetic ring arranged on the piston, thereby controlling the driving cylinder 125 to stop moving. The upper die set 123 is arranged inside the base 121 and connected to the moving end of the driving cylinder 125, and the upper die set 123 is provided with a first punching knife extending downward. The lower die set 122 is fixed on the base 121 and located directly below the upper die set 123, and the lower die set 122 is provided with a blanking opening and a mounting space. The channel for the first material belt c to pass through is formed between the upper die set 123 and the lower die set 122. The lower ends of the plurality of guide columns 124 can be arranged on the lower die set 122, and the upper ends of the guide columns 124 pass through the upper die set 123 and slide with the upper die set 123 to guide the movement of the upper die set 123 relative to the lower die set 122.

[0075] Therefore, after completing a punching work, the piston of the driving cylinder 125 retracts and the upper die set 123 can be driven to move upward and away from the first material belt c, at this time the first conveying device 11 can convey the first material belt c forward by a first distance to facilitate the punching mechanism 12 to punch the parts at the new position on the first material belt c, so as to facilitate the automation of the punching of the first material belt c.

[0076] Preferably, referring to Figure 4 The upper die set 123 can at least include a connecting plate 1231, a pressing plate 1232, and a plurality of pull rods and springs. The upper side of the connecting plate 1231 is connected to the moving end of the driving cylinder 125, and the lower side thereof is connected to the first punching knife. The pressing plate 1232 is provided with a through hole for the punch of the first punching knife to extend out. The first end of the pull rod can abut the pressing plate 1232 and the second end thereof is fixed on the connecting plate 1231; the spring is coaxially sleeved on the pull rod, and the two ends of the spring in the axial direction are respectively abutted between the opposite surfaces of the connecting plate 1231 and the pressing plate 1232.

[0077] In this embodiment, when the upper die set 123 descends, the pressing plate 1232 first presses the first material belt c near the cutting position, and then the connecting plate 1231 continues to move downward and the spring is compressed, in the process, the first punching knife cuts the first material belt c. Therefore, after the first material belt c is pressed near the cutting position, the first material belt c is cut, which is beneficial to improve the cutting effect. Thereafter, in the process of the upper die set 123 ascending, the connecting plate 1231 first ascends, the spring restores, and then the pull rod pulls the pressing plate 1232 away from the first material belt c.

[0078] Further, the connecting plate 1231 can be composed of an upper die holder, an upper die cushion and a clamping plate from top to bottom. In addition, the pressing plate 1232 can be composed of a stop plate and a stripper plate from top to bottom and be hung on the clamping plate to play a role of floating to press and strip materials. Furthermore, the lower die can be formed by fixing and connecting a lower die plate, a lower die cushion and a lower die holder from top to bottom to cooperate with the upper die set 123 to punch.

[0079] Preferably, referring to Figure 4 The upper die set 123 can be further provided with a second punch 128 connected to one side of the upper die set 123 and having a punch head downwardly arranged for cutting off the first material strip c. Since the first material strip c includes a material strip edge and a plurality of parts connected to the material strip edge and the plurality of parts are distributed along the length direction of the material strip edge at equal intervals, the second punch 128 can cut off the material strip edge at the position of the previous part while cutting off the parts on the first material strip c to avoid affecting the normal conveying of the second material strip b. In addition, a waste material pipeline 1221 can be arranged on the lower die set 122 to receive the cut-off material strip edge and further concentrate the processing of the material strip edge.

[0080] Preferably, referring to Figure 4 and Figure 5 The lower die set 122 can have a hole 1222 extending from the directly below the material dropping port to the other side of the lower die set 122 away from the installation space, and be further provided with a third driving device 127 and a material blocking rod 126. The third driving device 127 is fixedly arranged relative to the lower die set 122 and is arranged such that the moving end thereof extends and retracts along the hole 1222. The material blocking rod 126 is connected to the moving end of the third driving device 127 and has the other end extending to and retreating from the directly below the material dropping port. In this way, after the parts are cut off and fall onto the material guide rail 13 or the material pushing mechanism 130, the material blocking rod 126 can temporarily press or block the parts to avoid the interference of the position of the parts by the first punch 124 during the rising of the upper die set 123.

[0081] Preferably, referring to Figure 5 and Figure 6 The material guide rail 13 has a middle gap formed in the extending direction thereof, and the material pushing mechanism 130 can include a material pushing rod 132 and a movement mechanism 133 driving the material pushing rod 132 to move in a plane. The material pushing rod 132 is located below the material guide rail 13 and extends along the length direction of the middle gap and is provided with a plurality of material pushing grooves 1321 at intervals. Under the driving action of the movement mechanism 133, the material pushing rod 132 can retreat to the original position after pushing the plurality of parts forward by one step distance each time to perform the next pushing.

[0082] In this embodiment, when there are parts in the poking grooves 1321 of the poking rod 132, the movement mechanism 133 can drive the poking rod 132 to move one step towards the second conveying device 14, during which the poking rod 132 can transfer all the parts in its poking grooves 1321 one step forward, wherein the parts at the front end can be transferred to the predetermined position. Then the movement mechanism 133 drives the poking rod 132 to move one vertical distance downwards to a side away from the guide rail 13 without interfering with the parts, then drives the poking rod 132 to move one step away from the second conveying device 14, and then drives the poking rod 132 to move one vertical distance upwards towards the guide rail 13, so that the parts on the guide rail 13 and the next cut-off parts can fall into the poking grooves 1321 of the poking rod 132.

[0083] For example, referring to Figure 5 and Figure 6 , the movement mechanism 133 can include a fixed plate 1341, a wire rail 1332, a sliding block 1331, a first driving device 1344 and a second driving device 1345. The fixed plate 1341 is connected to the inside of the machine base 121, and a set of sliding holes are arranged thereon. The wire rail 1332 is arranged along the poking rod 132, and a set of sliding columns 1342 are connected to the lower side of the wire rail 1332 and slide-fitted with the corresponding sliding holes. The sliding block 1331 is slidably arranged on the wire rail 1332, and the poking rod 132 is connected to the upper side of the sliding block 1331, so that the poking rod 132 can move together with the wire rail 1332. The first driving device 1344 and the second driving device 1345 are both fixed on the fixed plate 1341, and the first driving device 1344 is arranged to drive the sliding block 1331 to slide horizontally along the wire rail 1332, and the second driving device 1345 is arranged to drive the sliding columns 1342 on the wire rail 1332 to vertically ascend and descend relative to the fixed plate 1341 along the sliding holes.

[0084] Preferably, in the above embodiment, the fixed plate 1341 can be connected with a sliding sleeve 1343 in the sliding holes, so that the sliding columns 1342 are directly slide-fitted with the sliding sleeve 1343. In addition, as Figure 6 , the lower end of the sliding column 1342 can also be connected with a stopper 13421, and the position of the stopper 13421 on the sliding column 1342 can be adjusted according to the height requirement of the movement of the wire rail 1332, so that the wire rail 1332 stops when it moves to the specified height.

[0085] Preferably, the first driving device 1344 can be a cylinder transversely arranged on the fixed plate 1341, and a limiting piece 135 and an extending piece 136 are arranged between the first driving device 1344 and the sliding block 1331. The limiting piece 135 is vertically arranged and connected at the lower end of the telescopic part of the first driving device 1344, and has a vertically extending long hole 1351. The extending piece 136 is connected to the sliding block 1331, and the first end of the extending piece 136 extends into the long hole 1351 and is in sliding fit with the long hole 1351. When the telescopic part of the first driving device 1344 is extended or retracted, the sliding block 1331 can be driven to move horizontally by the limiting piece 135 and the extending piece 136. When the second driving device 1345 drives the linear rail 1332 to vertically ascend or descend, the first end of the extending piece 136 can slide in the long hole 1351.

[0086] Preferably, referring to Figure 5 and Figure 6 , the second end of the extending piece 136 also extends to the other side of the sliding block 1331, and two position switches 137 are arranged on the material guide rail 13. The two position switches 137 are arranged on both sides of the second end of the extending piece 136, and the distance between the two position switches 137 is set such that when the material pushing rod 132 advances or retreats by one step, the extending piece 136 can turn on one position switch 137.

[0087] Exemplarily, the position switch 137 can be a travel switch, a micro switch or a proximity switch. When the first driving device 1344 drives the sliding block 1331 to move by a first step towards the second conveying device 14, one position switch 137 generates a first arrival signal; and when the first driving device 1344 drives the sliding block 1331 to retreat by a first step, the other position switch 137 generates a second arrival signal; wherein the first arrival signal and the second arrival signal are used for the control of the first driving device 1344. For example, the two position switches 137 and the first driving device 1344 can be connected to a controller signal.

[0088] The present application relates to the technical field of production and manufacturing of low-voltage air switches, in particular to a punching and transferring all-in-one machine 1 and a part feeding system. The punching and transferring all-in-one machine 1 comprises a machine base 121, and a punching mechanism 12, a material guide rail 13 and a material pushing mechanism 130 are arranged on the machine base 121. When a first material belt c is conveyed to a position where a part is located at the material falling port of the punching mechanism 12, the punching mechanism 12 works to cut off the part from the first material belt c, and the material pushing mechanism 130 can push the cut-off part to a predetermined position by means of the material guide rail 13. The punching and transferring all-in-one machine 1 can continuously push the trip bar a3 to the predetermined position where the trip bar a3 can be connected to the support a1 on the second material belt b, taking the trip bar a3 as the part. In this way, the automation and production efficiency of the assembly process of the low-voltage air switch can be improved.
