Description

Technical Field

[0001] This application relates to the technical field of the production and manufacturing of low-voltage air switches, particularly controllers and automatic connection systems. Background Art

[0002] There is a contact assembly in a low-voltage air switch. The contact assembly includes a bracket, a moving contact, a trip bolt, and two shaft rods arranged thereon. The moving contact is welded to one end of the bracket. One shaft rod is used to hinge the bracket to the trip bolt, and the other shaft rod is used to limit the rotation range of the bracket.

[0003] Currently, the production of the contact assembly adopts a manual operation method. The moving contact is welded to the bracket by holding a welding torch, and then the bracket is placed into the trip bolt, and the two are assembled together through the shaft rod. Since each process requires manual operation, the production efficiency of the contact assembly is low. Summary of the Invention

[0004] In view of this, this application proposes a controller and an automatic connection system to improve the production efficiency of the contact assembly.

[0005] In a first aspect, the controller is signal-connected to a second conveying device, a first conveying device, a set of punching and transfer integrated machine, a set of shaft-passing machines, a set of shaft-riveting machines, and a punching device of the automatic connection system. The shaft-passing machine, the shaft-riveting machine, and the punching device are sequentially arranged at integer multiples of a first distance in the downstream direction along the second conveying device. And the controller is configured to first control the second conveying device to convey a second strip forward by a second distance. After receiving a conveying completion signal that the second strip has been conveyed forward by the second distance, the controller is configured to perform control to simultaneously complete the following operations:

[0006] Control the first conveying device to convey a first strip forward by a first distance; control the punching and transfer integrated machine to cut off a part from the first strip; control the punching and transfer integrated machine to transport a part cut off before the conveyance of the second strip this time to a predetermined position where it can be connected to the component on the second strip; control the shaft-passing machine to pass a shaft rod through the through-hole for shaft-passing on the component and the part; control the shaft-riveting machine to rivet the shaft rod passed through before the conveyance of the second strip this time to the part, so as to connect the component and the part together and form a new target finished product; control the punching device to cut off a target finished product formed before the conveyance of the second strip this time from the second strip.

[0007] After receiving a feedback signal indicating that the above actions of the first conveying device, the punching and transfer integrated machine, the shaft-passing machine, the shaft-riveting machine, and the punching device have all been completed, control the second conveying device to continue to convey the second strip forward by the second distance.

During the process of the second strip stopping moving, the first conveying device can supply the release bolts to the punching and transfer integrated machine, and the punching and transfer integrated machine can transfer a release bolt to a predetermined position connectable to the brackets on the second strip. Then, a shaft-passing component of the shaft-passing machine passes a shaft rod through the shaft-passing holes on the brackets and the release bolts.

[0100] To make the purpose, technical solutions and advantages of this application clearer, the following examples are given to further elaborate on this application in detail.

[0101] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0102] As Figure 1 shown, on the second strip b, brackets a1 have been pre-cut at regular intervals, and a plurality of guide holes b1 have also been pre-formed on the second strip b at a set spacing. The guide holes b1 are used to cooperate with the guide pins of the positioning device, so that the second strip b cannot move longitudinally during the processing. During the transmission of the second strip b, every time the second strip b completes one transmission, other processing mechanisms can perform processing operations such as cutting, welding, riveting, and assembling on the second strip b at their respective stations, thereby processing the contact assembly.

[0103] On the first strip c, release bolts a3 have been pre-cut at regular intervals. During the transmission of the second strip b, the release bolts a3 are successively cut off from the first strip c and are toggled to a predetermined position where they can be connected to the brackets a1 on the second strip b. Then, through the riveting of the shaft rods a4 to the release bolts a3, the release bolts a3 are connected to the brackets a1 on the second strip b, and the contact assembly a is formed.

[0104] From Figure 1 it can be seen that the finally formed contact assembly a includes a bracket a1, a moving contact a2, a release bolt a3, and two shaft rods a4 provided thereon. The moving contact a2 is welded to one end of the bracket a1. One shaft rod a4 is used to hinge the bracket a1 to the release bolt a3, and the other shaft rod a4 is used to limit the rotation range of the bracket a1.

[0105] As Figure 2 shown, the automatic connection system can be used to realize Figure 1 the production and assembly of the contact assembly in. It should be noted that although this embodiment is described by taking the assembly of the contact assembly as an example, the automatic connection system of this embodiment can also be used in the production and assembly processes of other types of products through the selection and combination of different embodiments. The automatic connection system may include a second conveying device 14, a first conveying device 11, a set of punching and transfer integrated machine 1, a set of shaft-passing machines 2, a set of riveting shaft machines 30, and a punching device 5.

[0106] Among them, the second conveying device 14 conveys the second strip b placed on its feeding track 116. An element is provided on the second strip b at every second distance. For example, the element can be a bracket a1. The first conveying device 11 conveys the first strip c along a direction parallel to the second strip b. A part is provided on the first strip c at every first distance. For example, the part can be a release bolt a3. The punching, transferring and integrating machine 1 can punch the parts conveyed by the first conveying device 11 to its blanking port in sequence, and transfer a previously cut-off part to a predetermined position connectable to the element on the second strip b. The shaft-passing machine 2 includes a machine table 211 and at least one set of shaft-passing assemblies 21 provided on the machine table 211; the shaft-passing assemblies 21 are used to pass a shaft rod a4 through the shaft-passing holes on the element and the part. The riveting shaft machine 30 is arranged downstream of the shaft-passing machine 2 along the second conveying device 14 and is used to rivet the shaft rod a4 to the part to connect the element and the part together to form a new target finished product. For example, the finished product can be the above-mentioned contact assembly a. The punching device 5 is used to cut off a target finished product from the second strip b. In addition, the scrap on the second strip b can be cut off simultaneously. Among them, the shaft-passing machine 2, the riveting shaft machine 30 and the punching device 5 are arranged along the second conveying device 14 at integer multiples of the second distance in sequence. Optionally, a feeding pipe 55 can be arranged on one side of the punching device 5 to receive the cut-off scrap. The punching device 5 further includes a waste bin, and the waste bin can be placed directly below the feeding pipe 55 to collect the waste generated when punching the second strip b. In addition, a receiving bin can also be arranged at the discharge port of the punching device 5 to collect the target finished product.

[0107] During the working process of the automatic connection system of the present application, the first conveying device 11 continuously supplies the release bolt a3 to the punching, transferring and integrating machine 1, and the second conveying device 14 stops after conveying the second strip b and the bracket a1 thereon forward by a first distance. During the process of the second strip b stopping moving, the punching, transferring and integrating machine 1 transfers a release bolt a3 to a predetermined position connectable to the bracket a1 on the second strip b, and then a shaft-passing assembly 21 of the shaft-passing machine 2 passes a shaft rod a4 through the shaft-passing holes on the bracket a1 and the release bolt a3. At the same time, the riveting shaft machine 30 downstream of the shaft-passing machine 2 rivets two shaft rods a4 to the release bolt a3 respectively to connect and form the contact assembly a. In addition, the punching device 5 downstream of the riveting shaft machine 30 cuts off the contact assembly a from the second strip b. In this way, the automation of the production and assembly of the contact assembly a is realized, and the production efficiency of the contact assembly a can be improved.

[0108] Refer to Figure 3, the component supply system of this embodiment includes a first conveying device 11 and a punching and transfer integrated machine 1. Among them, the first conveying device 11 is used to convey the first strip c. The punching and transfer integrated machine 1 can successively punch the components conveyed by the first conveying device 11 to its blanking port, and the material pushing mechanism 130 of the punching and transfer integrated machine 1 is arranged to gradually push the components falling from the blanking port to a predetermined position where they can be connected to the components on the second strip b. Among them, the second strip b is conveyed by a second conveying device 14 along a direction parallel to the first strip c, and the second conveying device 14 is arranged at the end of the material guiding track 13 of the punching and transfer integrated machine 1. It should be noted that for simplicity, not all of the second conveying device 14 is shown in Figure 3 , and the main structure of the second conveying device 14 can refer to the first conveying device 11 during specific implementation.

[0109] As Figure 4 shown, the relevant mechanisms of the first conveying device 11 for realizing the material pulling function may include a first clamping mechanism 1141, a second clamping mechanism 1142, and a material pulling mechanism. Both the first clamping mechanism 1141 and the second clamping mechanism 1142 are arranged in the same straight line with the multi-section material feeding track 116, and are respectively used to clamp and release the first strip c, and the first clamping mechanism 1141 is fixedly arranged relative to the machine table. At the same time, the material pulling mechanism is used to drive the second clamping mechanism 1142 to move along the material feeding track 116. Among them, the material pulling mechanism and the first clamping mechanism 1141 can be relatively fixedly arranged on the machine table through a plurality of columns 112.

[0110] Preferably, in the first conveying device 11, there may also be two material guiding plates 111 respectively connected to the feeding end and the discharging end of the material feeding track 116, and the material guiding plates 111 are provided with arc-shaped guiding grooves 1111 that bend from the horizontal direction to the vertical direction, so that the first strip c can naturally droop along the arc-shaped guiding grooves 1111 on both the feeding side and the discharging side without the support of the material feeding track 116, and the first strip c will not be damaged.

[0111] Exemplarily, the first clamping mechanism 1141, the second clamping mechanism 1142, and a material pulling mechanism can all be cooperatively controlled by a controller. For example, the controller can be signal-connected to the first clamping mechanism 1141, the second clamping mechanism 1142, and the material pulling mechanism, and the controller is configured to: first control the first clamping mechanism 1141 to release the first strip c and the second clamping mechanism 1142 to clamp the first strip c, and then control the material pulling mechanism to act so that the second clamping mechanism 1142 drives the first strip c to move forward a first distance ( Figure 3(Moving leftward in the middle is the forward movement), a material pulling process is completed. After the first material tape c moves forward a first distance, control the first clamping mechanism 1141 to clamp the first material tape c and the second clamping mechanism 1142 to release the first material tape c, and then control the material pulling mechanism to act so that the second clamping mechanism 1142 moves backward a first distance to prepare for the next material pulling process.

[0112] Combined with Figure 4 , in a preferred embodiment, the above-mentioned first clamping mechanism 1141 and the second clamping mechanism 1142 may both include a frame 1151, a fixed clamping member 1152, a movable clamping member 1154 and a sixth driving device. Among them, the fixed clamping member 1152 is arranged at one end of the frame 1151 and is used to support the first material tape c, and the movable clamping member 1154 is arranged opposite to the fixed clamping member 1152 and is driven by the sixth driving device to move in a direction close to and away from the fixed clamping member 1152. Thus, when the sixth driving device drives the movable clamping member 1154 to move in a direction close to the fixed clamping member 1152, the movable clamping member 1154 can press the first material tape c supported on the fixed clamping member 1152; when the sixth driving device drives the movable clamping member 1154 to move in a direction away from the fixed clamping member 1152, the movable clamping member 1154 can release the first material tape c supported on the fixed clamping member 1152. For example, the fixed clamping member 1152 or the movable clamping member 1154 may be in a plate shape, a wedge shape, a column shape, etc. Preferably, the surface of the fixed clamping member 1152 or the movable clamping member 1154 facing the first material tape c is a plane with the same width as the first material tape c.

[0113] Continue to refer to Figure 4 , since the setting of the multi-segment material feeding track 116 needs to meet the requirement of supporting the first material tape c and the requirement of the moving space of the second clamping mechanism 1142. In a preferred embodiment, one segment of the material feeding track 116 may be respectively arranged on both sides of the frame 1151 of the first clamping mechanism 1141, and one segment of the material feeding track 116 is arranged on one side of the frame 1151 of the second clamping mechanism 1142. Among them, when the material pulling mechanism finishes moving backward a first distance, the material feeding track 116 between the second clamping mechanism 1142 and the first clamping mechanism 1141 is connected, and the second clamping mechanism 1142 is separated from the adjacent material feeding track 116 on the other side by a first distance. In this way, the reliability of the first conveying device 11 for conveying the first material tape c can be maintained on the premise of meeting the moving space requirement of the second clamping mechanism 1142.

[0114] Refer to Figure 5, the sixth driving device may include a first cylinder 1153, a first electromagnetic valve group, and a first magnetic switch. Among them, the first cylinder 1153 is arranged at the other end of the frame 1151. The first cylinder 1153 has a non-magnetic cylinder barrel and a piston made of a non-magnetic material, and a permanent magnetic ring is arranged on the piston. The first electromagnetic valve group is connected to the air path 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 conduct when the piston drives the moving clamp 1154 to move to the position where the first strip c is clamped.

[0115] In a preferred embodiment, the controller is also signal-connected to the first electromagnetic valve group and the first magnetic switch of the first clamping mechanism 1141 and the second clamping mechanism 1142, and the controller is configured to: control the first electromagnetic valve group to make the moving clamp 1154 move in the directions close to and away from the fixed clamp 1152; and when the controller receives the signal fed back by the first magnetic switch that changes from off to on, control the first electromagnetic valve group to make the moving clamp 1154 stop moving.

[0116] Thus, the first clamping mechanism 1141 and the second clamping mechanism 1142 can control their electromagnetic valve groups by the controller to control the air path of the first cylinder 1153 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 conducts, and the controller determines accordingly that the first clamping mechanism 1141 or the second clamping mechanism 1142 has clamped the first strip c. In addition, when the first clamping mechanism 1141 or the second clamping mechanism 1142 releases the first strip c, the piston can be retracted to the initial position.

[0117] Preferably, when the controller does not receive the signal fed back by the first magnetic switch that changes from off to on within the set time period, an alarm signal is issued. This embodiment is for detecting the failure that the first clamping mechanism 1141 or the second clamping mechanism 1142 cannot normally clamp the first strip c, so as to ensure that the person in charge is notified in time for troubleshooting.

[0118] It should be noted that although the sixth driving device in this embodiment is described by taking the first cylinder 1153 as an example, the above functions of the first clamping mechanism 1141 or the second clamping mechanism 1142 can still be achieved by motor drive.

[0119] Continue to refer to Figure 4, in an alternative embodiment, the material pulling mechanism includes a first slide rail 1131, a moving member 1133 and a fifth driving mechanism. The first slide rail 1131 is arranged on the machine table and extends along the material feeding track 116. The moving member 1133 is slidably arranged on the first slide rail 1131, and the second material clamping mechanism 1142 is arranged on the moving member 1133. For example, limiting bars can be arranged on both sides of the moving member 1133, and limiting grooves can be formed on the inner walls of both sides of the first slide rail 1131, so that the moving member 1133 can be slidably matched with the first slide rail 1131. For another example, a slider 1331 can also be slidably arranged in the first slide rail 1131, and the moving member 1133 is connected to the slider 1331 to realize the sliding connection of the moving member 1133 relative to the first slide rail 1131. Wherein, the controller is in signal connection with the fifth driving mechanism. The controller can control the fifth driving mechanism to drive the moving member 1133 to move along the first slide rail 1131, so that the second material clamping mechanism 1142 can pull the first material tape c forward by a first distance.

[0120] Continue to refer to Figure 4 , the above-mentioned fifth driving mechanism can include a material pulling motor 113, a lead screw shaft 1132 and at least one photoelectric switch. The lead screw shaft 1132 is rotatably arranged on the first slide rail 1131, and one end of the lead screw shaft 1132 is connected to the output end of the material pulling motor 113. The lead screw shaft 1132 also drives the moving member 1133 to move by means of screw transmission. For example, both ends of the lead screw shaft 1132 can be respectively arranged on the track through a bearing, so that the lead screw shaft 1132 can be rotatably connected to the first slide rail 1131. The photoelectric switch can be arranged on the machine table and is set to be turned on when the moving member 1133 moves forward by the first distance.

[0121] Exemplarily, the first conveying device 11 can know the pulse requirements for the material pulling mechanism to drive the second material clamping mechanism 1142 to move forward or backward by the first distance according to prior tests. For example, when the material pulling motor 113 is a stepping motor, the rotation angle can be controlled by controlling the number of pulses; when the material pulling motor 113 is a servo motor, the rotation angle can be controlled by controlling the length of the pulse time. In this way, the moving distance of the material pulling mechanism driving the second material clamping mechanism 1142 can be controlled.

[0122] Preferably, the controller can be signal - connected to the pulling motor 113 and the photoelectric switch. The controller is further configured to: control the rotation angle of the pulling motor 113 by controlling the number of pulses or the time for sending pulses to the pulling motor 113, so as to drive the second clamping mechanism 1142 to move forward or backward. When receiving the signal fed back by the photoelectric switch that changes from off to on, it controls the pulling motor 113 to stop. According to this embodiment, in an ideal situation, the pulling motor 113 can complete the task of driving the second clamping mechanism 1142 to move forward or backward by a first distance according to the set pulse parameters, and the photoelectric switch can just send a feedback signal to the controller at this time. In addition, the photoelectric switch can also be used to correct the accuracy problems such as the "out - of - step" of the pulling motor 113 after the fifth driving mechanism operates for a period of time, ensuring the accuracy and reliability of the first conveyor 11 for conveying the first strip c.

[0123] It should be noted that although the above - mentioned embodiment is described by taking the fifth driving mechanism including the pulling motor 113 as an example, the fifth driving mechanism can also adopt a cylinder as the power device to realize the above functions of the pulling mechanism.

[0124] Refer to Figure 3 and 5 As shown in [relevant figure numbers] and [relevant figure numbers], the punching - cutting and transferring integrated machine 1 includes a first machine base 121, and a punching - cutting mechanism 12, a guiding track 13 and a material - shifting mechanism 130 are arranged on the first machine base 121. The punching - cutting mechanism 12 is used to cut off the parts on the first strip c passing through it. It has a blanking port for the cut - off parts to fall, and an installation space communicating with the blanking port is formed at the lower part of the punching - cutting mechanism 12. One end of the guiding track 13 is located in the installation space and the other end extends out from one side of the punching - cutting mechanism 12, and its extending direction is perpendicular to the length direction of the first strip c in space. The material - shifting mechanism 130 is configured to shift the parts falling from the blanking port to the guiding track 13, and shift the parts on the guiding track 13 to a predetermined position.

[0125] In the punching - cutting and transferring integrated machine 1 provided in this embodiment, when a part on the first strip c is located at the blanking port of the punching - cutting mechanism 12 during the conveyance of the first strip c, the punching - cutting mechanism 12 works and cuts off a part from the first strip c. With the help of the guiding track 13, the material - shifting mechanism 130 can shift the cut - off part to a predetermined position. The punching - cutting and transferring integrated machine 1 can use the release bolt a3 as the part, and continuously shift the release bolt a3 to a predetermined position where it can be connected to the bracket a1 on the second strip b, so as to prepare for connecting the release bolt a3 to the bracket a1 on the second strip b. In this way, the automation and production efficiency of the assembly process of the low - voltage air switch can be improved.

[0126] Continue to refer to Figure 5, the punching mechanism 12 may include a driving cylinder 125, an upper die set 123, a lower die set 122, and a set of first guide posts 124. The driving cylinder 125 may be disposed at the top of the first base 121 with its moving end facing downward. For example, at least one magnetic switch may be provided on the driving cylinder 125 to determine that the piston and the upper die set 123 have moved to a preset position by cooperating with a permanent magnet ring provided on the piston, thereby controlling the driving cylinder 125 to stop moving. The upper die set 123 is located inside the first base 121 and is 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 therefrom. The lower die set 122 is fixed on the first base 121 and is located directly below the upper die set 123, and the lower die set 122 is provided with a blanking port and an installation space. Wherein, a channel for the first strip c to pass through is formed between the upper die set 123 and the lower die set 122. And, the lower ends of the plurality of first guide posts 124 may be provided on the lower die set 122, and the upper ends of the first guide posts 124 pass through the upper die set 123 and are slidably engaged with the upper die set 123 to guide the movement of the upper die set 123 relative to the lower die set 122.

[0127] Thus, after completing a punching operation, the piston of the driving cylinder 125 retracts and can drive the upper die set 123 to move upward and away from the first strip c. At this time, the first conveying device 11 can convey the first strip c forward by a next first distance for the punching mechanism 12 to punch the parts at a new position on the first strip c, so as to facilitate the realization of the automation of punching the first strip c.

[0128] Preferably, referring to Figure 5 , the upper die set 123 may at least include: a connecting plate 1231, a pressing plate 1232, and a plurality of tie rods and springs. Wherein, 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 with a first punching knife. The pressing plate 1232 is provided with a through hole for the punch head of the first punching knife to extend out. The first end of the tie rod can support the pressing plate 1232 and the second end is fixed on the connecting plate 1231; the spring is coaxially sleeved on the tie rod, and the two axial ends of the spring respectively abut between the opposite surfaces of the connecting plate 1231 and the pressing plate 1232.

[0129] In this embodiment, when the upper die set 123 descends, the pressing plate 1232 first presses the vicinity of the cutting position of the first strip c, and then the connecting plate 1231 continues to move downward and the spring is compressed. During this process, the first punching knife cuts the first strip c. Thus, cutting the first strip c after pressing the first strip c near the cutting position is beneficial to improving the cutting effect. Thereafter, during the ascending process of the upper die set 123, the connecting plate 1231 first ascends, the spring resumes its original state, and then the tie rod pulls the pressing plate 1232 away from the first strip c.

[0130] Further, the connecting plate 1231 can be composed of an upper die base, an upper backing plate, and a clamping plate connected from top to bottom. Also, the pressure plate 1232 can be composed of a stop plate and a stripper plate fixed together from top to bottom and hung on the clamping plate to float and play the roles of pressing and stripping materials. In addition, the lower die can be formed by fixedly connecting a lower template, a lower backing plate, and a lower die base from top to bottom, and cooperate with the upper die set 123 for punching.

[0131] Preferably, referring to Figure 5 , the upper die set 123 can also be provided with a second punching knife 128. The second punching knife 128 is connected to one side of the upper die set 123 and the punch head is arranged downward, and is used to cut off the protruding first strip c. Among them, since the first strip c includes a strip edge and a plurality of parts connected to the strip edge, and the plurality of parts are distributed at equal intervals along the length direction of the strip edge, when the parts on the first strip c are cut off, the strip edge at the position of the previous part can be cut off by the second punching knife 128 at the same time to avoid affecting the normal transmission of the second strip b. In addition, a waste pipe 1221 can be provided on the lower die set 122 to receive the cut-off strip edge and further centrally process the strip edge.

[0132] Preferably, referring to Figure 5 and Figure 6 , the lower die set 122 can have a hole 1222. The hole 1222 extends from directly below the blanking port away from the installation space to the other side of the lower die set 122. The lower die set 122 is also provided with a third driving device 127 and a stop lever 126. The third driving device 127 is fixedly arranged relative to the lower die set 122, and is arranged such that its moving end expands and contracts along the hole 1222. The stop lever 126 is connected to the moving end of the third driving device 127, so that the other end thereof can extend to directly below the blanking port and retreat from the blanking port. Thus, when the parts fall onto the material guiding track 13 or the material dialing mechanism 130 after being cut off, the parts can be temporarily pressed or blocked by the stop lever 126 to avoid interfering with the position of the parts when the first punching knife withdraws during the upward movement of the upper die set 123.

[0133] Preferably, referring to Figure 6 and Figure 7 , the material guiding track 13 forms a middle gap in its extending direction. The material dialing mechanism 130 can include a material dialing rod 132 and a moving mechanism 133 for driving the material dialing rod 132 to perform a planar movement. Among them, the material dialing rod 132 is located below the material guiding track 13, and extends along the length direction of the middle gap and is provided with a plurality of material dialing grooves 1321 at intervals. Under the driving action of the moving mechanism 133, after the material dialing rod 132 moves the plurality of parts forward by a third distance each time, it can retreat to the original position for the next movement.

[0134] In this embodiment, when there are parts in the material pushing grooves 1321 of the material pushing rod 132, the movement mechanism 133 can drive the material pushing rod 132 to move a third distance towards the second conveying device 14. During this movement, the material pushing rod 132 can transfer all the parts in its multiple material pushing grooves 1321 forward by a third distance. Among them, the part at its front end can be transferred to a predetermined position. Then the movement mechanism 133 drives the material pushing rod 132 to move downward by a vertical distance to a side that does not interfere with the parts and is away from the material guiding track 13, and then drives the material pushing rod 132 to move away from the second conveying device 14 by a third distance, and then drives the material pushing rod 132 to move upward by a vertical distance towards the material guiding track 13, so that the parts on the material guiding track 13 and the next cut-off part can fall into its material pushing grooves 1321 again.

[0135] Exemplarily, referring to Figure 6 and Figure 7 , the movement mechanism 133 can include a first fixing plate 1341, a first linear guide 1332, a slider 1331, a first driving device 1344 and a second driving device 1345. Among them, the first fixing plate 1341 is connected inside the first machine base 121, and a set of sliding holes are provided thereon. The first linear guide 1332 is arranged along the material pushing rod 132, and a set of sliding columns 1342 that are slidably matched with the corresponding sliding holes are connected to the lower side thereof. The slider 1331 can be slidably arranged on the first linear guide 1332, and the material pushing rod 132 is connected thereto, so that the material pushing rod 132 can move together with the first linear guide 1332. The first driving device 1344 and the second driving device 1345 can both be fixed on the first fixing plate 1341. The first driving device 1344 is arranged to drive the slider 1331 to slide horizontally along the first linear guide 1332, and the second driving device 1345 is used to drive the first linear guide 1332 to vertically lift relative to the first fixing plate 1341 along the sliding columns 1342.

[0136] Preferably, in the above embodiment, a sliding sleeve 1343 can be connected in the sliding holes of the first fixing plate 1341, so that the sliding columns 1342 are directly slidably matched with the sliding sleeve 1343. In addition, as Figure 7 , a stopper 13421 can also be connected to the lower end of the sliding column 1342, 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 first linear guide 1332, so that the first linear guide 1332 stops when it moves to a specified height.

[0137] Preferably, the first driving device 1344 can be a cylinder horizontally arranged on the first fixing plate 1341. A limiting member 135 and an extending member 136 are arranged between the first driving device 1344 and the slider 1331. The limiting member 135 is vertically arranged and its lower end is connected to the telescopic part of the first driving device 1344, and it has a vertically extending long slot 1351. The extending member 136 is connected to the slider 1331, and its first end extends into the long slot 1351 and is slidably matched with the long slot 1351. So that when the telescopic part of the first driving device 1344 expands and contracts, the slider 1331 can be driven to move horizontally through the limiting member 135 and the extending member 136. And, when the second driving device 1345 drives the first linear guide 1332 to vertically lift and lower, the first end of the extending member 136 can slide in the long slot 1351.

[0138] Preferably, referring to Figure 6 and Figure 7 , the second end of the extending member 136 also extends to the other side of the slider 1331, and two position switches 137 are further arranged on the material guiding track 13. The two position switches 137 are arranged on both sides of the second end of the extending member 136, and the distance between the two position switches 137 is set such that when the dialing rod 132 advances or retreats a third distance, the extending member 136 can conduct one of the position switches 137.

[0139] 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 slider 1331 to move a third distance towards the second conveying device 14, one of the position switches 137 generates a first in-place signal; and, when the first driving device 1344 drives the slider 1331 to retreat a first distance, the other position switch 137 generates a second in-place signal; wherein, the first in-place signal and the second in-place signal are used for the control of the first driving device 1344. For example, these two position switches 137 and the first driving device 1344 can all be signal-connected to a controller.

[0140] During the conveying of the second strip b, as Figure 8 shown, the part supply system is used to cut off the release bolt a3 from the first strip c in sequence and dial it to a preset position on the second strip b, so as to prepare to connect the release bolt a3 to the bracket a1 on the second strip b by the shaft rod a4 using the shaft-piercing machine 2 of this embodiment.

[0141] Referring to Figure 8, in the shaft-passing connection system provided in this embodiment, there is a shaft-passing machine 2, two vibrating bowls 22 and a set of positioning devices 24. Among them, the shaft-passing machine 2 is used to pass the shaft rod a4 through the corresponding shaft-passing holes of the release bolt a3 and the bracket a1 of the second strip b, so as to preliminarily connect the release bolt a3 to the bracket a1. The vibrating bowl 22 can continuously supply the shaft rod a4 to the shaft-passing machine 2, and the positioning device 24 can position the second strip b before the shaft-passing connection, so that the shaft-passing machine 2 can accurately pass the shaft rod a4 through the release bolt a3 and the bracket a1.

[0142] As Figure 8 shown, the vibrating bowl 22 includes a hopper 221 and a vibrator 222 arranged on the outer wall of the hopper 221. The vibrator 222 is used to drive the hopper 221 to vibrate. Among them, a spiral track 2211 is further formed on the inner wall of the hopper 221. The spiral track 2211 extends from bottom to top to a discharge port 2212. The discharge port 2212 is connected to the shaft inlet hole 2121 of the shaft-passing machine 2 through a shaft transmission pipe.

[0143] In this embodiment, after placing a batch of shaft rods a4 in the hopper 221 of the vibrating bowl 22, when the vibrator 222 vibrates, each shaft rod a4 can be sequentially arranged in the bottom of the spiral track 2211 and move upward along the spiral track 2211. When the shaft rod a4 moves to the discharge port 2212 of the vibrating bowl 22, the shaft rod a4 can enter the shaft inlet hole 2121 of the shaft-passing machine 2 along the shaft transmission pipe. In addition, the vibrating bowl 22 can also be configured with a frequency converter to adjust the vibration frequency of the vibrator 222 to meet the supply requirements of different workpieces. It should be noted that the part supply system of this embodiment can not only be used for the assembly of the contact component a, but also for the assembly of other devices.

[0144] Refer to Figure 9, the shaft threading machine 2 includes a machine table 211 and at least one shaft threading assembly 21 arranged on the machine table 211. Among them, one shaft threading assembly 21 may include a guide cylinder 212, a second guide column 213 and an ejector pin 2141. The guide cylinder 212 may be connected to the table of the machine table 211 and parallel to the table. One end of the upper side wall of the guide cylinder 212 is provided with an inlet shaft hole 2121 and the other end is provided with an outlet shaft hole 2122. The lower side wall and the table of the guide cylinder 212 are both provided with a pinhole, and the pinhole and the outlet shaft hole 2122 are located on the same axis. The main body of the second guide column 213 extends into the guide cylinder 212 and is driven by the first driving mechanism 2131, and the second guide column 213 and the guide cylinder 212 are limitedly matched to slide only along the guide cylinder 212. In addition, a shaft-moving hole is provided on the main body, and before and after the second guide column 213 moves the shaft, the shaft-moving hole can be coaxial and connected with the shaft-entry hole 2121 and the shaft-exit hole 2122. The ejector pin 2141 is located below the table and connected to the moving end of the second driving mechanism 214, and the ejector pin 2141 faces and is directly opposite to the needle hole.

[0145] For example, in combination Figure 8 In the embodiment where the shaft threading machine 2 is used for the assembly of the contact assembly a, the shaft threading machine 2 can be configured such that the shaft outlet hole 2122 of the guide cylinder 212 is located below the material track 116 of the second conveyor, and the second conveyor is used to convey the second material belt b on its material track 116. The shaft threading machine 2 can thread the shaft rod a4 entering from its shaft inlet hole 2121 through the shaft outlet hole 2122 on the shaft threading hole of the second material belt b. It should be noted that although the shaft threading machine 2 of this embodiment is described by taking the assembly of the contact assembly a as an example, the shaft threading machine 2 of this embodiment can also be used in other application scenarios of products with shaft threading requirements.

[0146] In this embodiment, when the shaft transport hole of the second guide column 213 faces the shaft entry hole 2121 on the guide cylinder 212, the shaft rod a4 can enter the shaft transport hole of the second guide column 213 through the shaft entry hole 2121 on the guide cylinder 212, and then the first driving mechanism 2131 drives the second guide column 213 to move along the guide cylinder 212 to the position where the shaft transport hole faces the shaft exit hole 2122. At this time, the second driving mechanism 214 drives the ejector pin 2141 to sequentially extend into the table and the needle hole of the guide cylinder 212, and eject the shaft rod a4 out of the shaft exit hole 2122 of the guide cylinder 212, and further enables the shaft rod a4 to pass through the bracket a1 on the second material strip b and the shaft threading hole of the release bolt a3, so as to realize the preliminary connection between the release bolt a3 and the bracket a1 on the second material strip b. In this way, the shaft threading machine 2 can improve the efficiency of the connection between the release bolt a3 and the bracket a1 through automatic control, and is conducive to the automated production of the contact assembly a.

[0147] In an alternative embodiment, a first hole portion communicating with the shaft moving hole may be provided on the side wall of the second guide post 213, and a second hole portion may be formed on the side wall of the guide cylinder 212. When the shaft moving hole is located at a position coaxial with the shaft entering hole 2121, the first hole portion and the second hole portion are also coaxial and jointly form a detection hole. In addition, the shaft piercing machine 2 may further include a material detector 2123, which is configured to detect whether there is a shaft rod a4 in the shaft moving hole through the detection hole. For example, the material detector 2123 may be a photoelectric inductor.

[0148] In this embodiment, the material detector 2123, the first driving mechanism 2131 and the signal may be connected to the same controller. When the material detector 2123 detects that there is a shaft rod a4 in the shaft moving hole, it feeds back a detection signal to the controller, and the controller controls the first driving mechanism 2131 to drive the second guide post 213 to move according to the detection signal.

[0149] In an alternative embodiment, the first driving mechanism 2131 or the second driving mechanism 214 may be a cylinder, and at least one magnetic switch 215 is provided on the outer wall of the cylinder barrel of the cylinder. The magnetic switch 215 determines whether the piston moves to a preset position by cooperating with a permanent magnet ring provided on the piston, and generates a position detection signal.

[0150] In this embodiment, the first driving mechanism 2131 or the second driving mechanism 214 may be signal-connected to the corresponding magnetic switch 215 on a controller. The controller can determine that the second guide post 213 or the ejector pin 2141 has moved to the set position through the feedback signal of the magnetic switch 215, and controls the first driving mechanism 2131 or the second driving mechanism 214. For example, referring to Figure 9 , two magnetic switches 215 are provided on the outer wall of the cylinder barrel of the first driving mechanism 2131, and respectively correspond to the positions where the shaft moving hole is opposite to the shaft entering hole 2121 and the shaft leaving hole 2122. In this way, the moving position of the second guide post 213 can be accurately controlled. It should be noted that although this embodiment describes the first driving mechanism 2131 and the second driving mechanism 214 by taking a cylinder as an example, the first driving mechanism 2131 and the second driving mechanism 214 may also be driving mechanisms powered by a motor or a hydraulic cylinder.

[0151] Combined with Figure 8 and Figure 9, in a preferred embodiment of the shaft threading machine 2, the shaft threading machine 2 further includes an alignment device 23, and the alignment device 23 includes a second slide rail 231, an alignment plate 232 and a third driving mechanism 234. Among them, the second slide rail 231 is arranged on the table surface of the machine table 211 and is parallel to the guide cylinder 212. The alignment plate 232 is slidably arranged relative to the second slide rail 231 and is located above the guide cylinder 212, and at least one notch 2321 through which the shaft rod a4 can pass is formed at one end of the alignment plate 232 close to the shaft outlet hole 2122. The alignment plate 232 can be moved to a position where the notch 2321 is coaxial with the shaft outlet hole 2122, and the alignment plate 232 covers the second strip b. The third driving mechanism 234 is arranged to drive the alignment plate 232 to slide along the second slide rail 231. Among them, a slider can be arranged on the second slide rail 231, and then the alignment plate 232 is connected to the slider to realize the function of the alignment plate 232 being slidably arranged relative to the second slide rail 231.

[0152] In this embodiment, before the shaft threading machine 2 threads the shaft rod a4 onto the second strip b and the release bolt a3, the third driving mechanism 234 can drive the alignment plate 232 above the second strip b, and the alignment plate 232 covers the release bolt a3 to prevent the second strip b or the release bolt a3 from being deflected during the shaft threading process. And, the position and number of the notches 2321 on the alignment plate 232 correspond to the position and number of the shaft threading positions on the second strip b to allow the shaft rod a4 to pass through normally during the shaft threading process.

[0153] Continue to refer to Figure 9 , in the embodiment where the shaft threading machine 2 is used for the assembly of the contact assembly a, two sets of shaft threading assemblies 21 are arranged on the machine table 211, and the guide cylinders 212 of the two sets of shaft threading assemblies 21 are respectively arranged parallel to both sides of the second slide rail 231. The two sets of shaft threading assemblies 21 are respectively used to thread different shaft rods a4 through different shaft threading holes of the second strip b. Correspondingly, in Figure 8 it can be seen that there are two vibrating discs 22 in the shaft threading connection system, which supply the shaft rods a4 to different shaft threading assemblies 21 respectively.

[0154] Combined with Figure 8 and Figure 10, the positioning device 24 in the shaft-passing connection system will be described. The positioning device 24 includes a base 241, at least one second linear guide 243 provided on the base 241, a positioning plate 244 slidably arranged on the second linear guide 243, and a fourth driving mechanism 242. Among them, the base 241 is fixedly arranged relative to the machine table 211, and the base 241 is provided with a mounting table located above the guide cylinder 212 of the shaft-passing machine 2. The second linear guide 243 is arranged on the mounting table and one end faces the machine table 211. The positioning plate 244 is slidably arranged along the second linear guide 243, and at least one positioning pin 2441 is arranged on the positioning plate 244; among them, one end of the positioning pin 2441 is connected to the positioning plate 244 through a spring, and the other end faces the shaft-passing hole 2122. The fourth driving mechanism 242 is configured to drive the positioning plate 244 to slide along the second linear guide 243, and can make the positioning pin 2441 extend into the shaft-passing hole on the second strip b to position the second strip b.

[0155] Exemplarily, in an embodiment where the shaft-passing machine 2 is used for assembling the contact component a, two positioning pins 2441 are arranged on the positioning plate 244, and one positioning pin 2441 faces the shaft-passing hole 2122 on the guide cylinder 212 of a set of shaft-passing components 21. Before the shaft rod a4 is passed through the second strip b by the shaft-passing machine 2, the fourth driving mechanism 242 first drives the positioning plate 244 to move along the second linear guide 243 until the positioning pin 2441 passes through the shaft-passing holes on the bracket a1 and the release bolt a3. The diameter of the positioning pin 2441 is smaller than that of the shaft rod a4. Passing through the shaft-passing hole in advance can play a role in aligning the release bolt a3 and the shaft-passing hole on the second strip b, so that the shaft-passing machine 2 can accurately pass the shaft rod a4 through the release bolt a3 on the second strip b.

[0156] In a preferred embodiment, at least one first pressing rod 2442 can also be arranged on the positioning plate 244 in the positioning device 24. In this way, when the fourth driving mechanism 242 drives the positioning pin 2441 to pass through the release bolt a3 and the shaft-passing hole on the second strip b, the first pressing rod 2442 can press on the corresponding release bolt a3 to prevent the release bolt a3 from moving wrongly. Figure 10 As can be seen, there are also two first pressing rods 2442, which can respectively correspond to different release bolts a3.

[0157] In a preferred embodiment, continue to refer to Figure 10 , at least one catheter holder 246 can also be arranged on the positioning plate 244 in the positioning device 24. A limiting hole is arranged on the catheter holder 246, and the limiting hole can be passed through by the shaft delivery tube. In this way, the shaft delivery tube connecting the discharge port 2212 of the vibrating disk 22 to the shaft inlet hole 2121 of the shaft-passing machine 2 can pass through the limiting hole to position the shaft delivery tube. Refer to Figure 10, the jacket 246 can be provided with two, respectively positioning the transmission shaft pipes connected to the two vibrating discs 22.

[0158] In a preferred embodiment, continue to refer to Figure 10 , at least one positioning block 245 can also be connected to the positioning plate 244 of the positioning device 24. At least one guiding pin 2451 is also provided on the positioning block 245. The guiding pin 2451 faces the second tape b and can be moved by the driving of the fourth driving mechanism 242 to penetrate into the guiding hole b1 on the second tape b.

[0159] Exemplarily, after the second conveying device conveys the second tape b forward by a second distance on the feeding track 116 each time, the shaft-piercing rod a4 is required, and the position of the second tape b also needs to be accurate. By inserting the guiding pins 2451 at different positions of the positioning device 24 into different guiding holes b1 on the second tape b, the function of guiding the tape is achieved. In addition, when the guiding pin 2451 cannot be inserted into the guiding hole b1 of the tape, an alarm signal can be given to remind or monitor accidents such as incorrect conveying distance or tape deviation during tape conveying, so that problems can be found in time during the processing of the contact component a, accidents can be avoided, and the normal operation of the equipment can be ensured.

[0160] As Figure 11 shown, the riveting machine 30 provided in this embodiment includes a flattening mechanism 3 and a pressing mechanism 4. The flattening mechanism 3 is used to press and form a lateral protrusion on the shaft rod a4, and the pressing mechanism 4 is used to further press the shaft rod a4 into the shaft-piercing hole of the release bolt a3, so that a riveting fit is formed between the lateral protrusion and the shaft-piercing hole. The specific structure and working process of the riveting machine 30 will be described below, and the clamp 31 used in the flattening mechanism 3 will be described in detail.

[0161] As Figure 11 shown, the riveting machine 30 is used to rivet the shaft rod a4 to the shaft-piercing hole on the part. For example, the part can be the release bolt a3. In the application of the production and assembly of the contact component a in this embodiment, the shaft rod a4 has passed through the part and is connected to the second tape b. The second tape b is located on the feeding track 116 of the second conveying device and can be conveyed. Refer to Figure 11 , the second tape b is conveyed from left to right. It should be noted that although the riveting machine 30 in this embodiment is described by taking the production and assembly of the contact component a as an example, the riveting machine 30 can also be used in other scenarios where the shaft rod a4 needs to be riveted to the part.

[0162] The riveting shaft machine 30 includes at least one flattening mechanism 3 and at least one pressing mechanism 4. The flattening mechanism 3 includes a pair of pliers 31 and a lifting mechanism 32 for driving the pair of pliers 31 to move up and down. The lifting mechanism 32 is used to lift the pair of pliers 31 to a position where the riveting portion of the shaft rod a4 can be clamped. The pressing mechanism 4 includes a second pressing rod 421 and a second driving device 423 for driving the second pressing rod 421 to move linearly. The second pressing rod 421 presses one end of the shaft rod a4 under the drive of the second driving device 423, so that at least part of the lateral protrusion of the shaft rod a4 extends into the shaft hole and is riveted to the part. Wherein, at least one pressing mechanism 4 is arranged downstream of the feeding track 116 relative to at least one flattening mechanism 3.

[0163] During the operation of the flattening mechanism 3 of the riveting shaft machine 30, the lifting mechanism 32 needs to first move the pair of pliers 31 to a position where the shaft rod a4 can be clamped, and then the pair of pliers 31 acts to clamp the riveting portion of the shaft rod a4 to form a lateral protrusion. After the clamping, the lifting mechanism 32 drives the pair of pliers 31 to leave the shaft rod a4, and the second conveying device conveys the second strip b. The clamped shaft rod a4 is conveyed to the station where the pressing mechanism 4 is located along with the second strip b. The second driving device 423 drives the second pressing rod 421 to press one end of the shaft rod a4 and realizes riveting with the part. Subsequently, the second driving device 423 can drive the second pressing rod 421 to leave the shaft rod a4.

[0164] The flattening mechanism 3 and the pressing mechanism 4 of the riveting shaft machine 30 can work simultaneously to complete their respective tasks. Wherein, since the exposed length of the shaft rod a4 connected to the part is certain, the flattening mechanism 3 can sequentially clamp the same position of different shaft rods a4, and the pressing mechanism 4 can press the shaft rod a4 to its final exposed length value, so as to realize standard riveting between the shaft rod a4 and the part during the processing. Thus, it is beneficial to realize the automation of the production and assembly process of the contact assembly a and improve the production efficiency of the contact assembly a.

[0165] Exemplarily, referring to Figure 11 , the lifting mechanism 32 may include a connecting seat 321, a pair of sliding rods 322 and a fourth driving device 323. The connecting seat 321 is connected to the pair of pliers 31 on the other side of the feeding track 116, and a guiding hole is respectively arranged at both ends of the connecting seat 321. A pair of sliding rods 322 are respectively arranged to slide through a guiding hole, one end is connected to the fixed seat 313 of the pair of pliers 31, and the other end is connected to the same mounting plate 324. The fourth driving device 323 is arranged between the connecting seat 321 and the mounting plate 324 and drives the mounting plate 324 to drive the pair of pliers 31 to move up and down. As Figure 11In the embodiment, the fourth driving device 323 is a cylinder, the cylinder body of the cylinder is connected to the mounting plate 324, the end of the piston of the cylinder passes through the mounting plate 324 and is connected to the connecting seat 321, so that the size of the cylinder is not affected by the space between the mounting plate 324 and the connecting plate. In addition, the cylinder can also be installed in other ways, and the fourth driving device 323 can also be selected as a motor-driven telescopic device, etc.

[0166] For example, in combination Figure 11 and Figure 12 , the pressing mechanism 4 may include a fixed frame 41, a first connecting block 42 and a second connecting block 43. At least one guide rail 411 is provided on the fixed frame 41, and the guide rail 411 extends to the upper and lower sides of the feeding track 116. The first connecting block 42 is slidably arranged on the guide rail 411 and is located on a side of the transverse protrusion close to the shaft a4, and a second pressing rod 421 is arranged thereon, and a second driving device 423 is connected to the fixed frame 41 and drives the first connecting block 42 to slide. The second connecting block 43 is slidably arranged on the guide rail 411 and is located on a side of the transverse protrusion away from the shaft a4, and a positioning member 431 facing the part is arranged thereon; the fifth driving device 432 is connected to the fixed frame 41 and drives the second connecting block 43 to slide. For example, the positioning member 431 may be tubular. Thus, before the pressing mechanism 4 presses the shaft a4, the fifth driving device 432 can first drive the second connecting block 43 to move and make the positioning member 431 abut against the component, so that the component will not be deformed when pressing the shaft a4.

[0167] Preferably, the pressing mechanism 4 further includes a buffer device 422, which is arranged on the first connecting block 42, so that when the second pressing rod 421 rivets the shaft a4 to the part, it presses against the material feeding track 116, so as to reduce the impact and vibration when the second driving device 423 moves the second pressing rod 421 to the terminal position, thereby protecting the riveting machine 30 itself and reducing the damage to the contact assembly a. For example, the buffer device 422 can achieve the effect of buffering and shock absorption by rubber or spring.

[0168] Continue to refer to Figure 11 and Figure 12 In this riveting machine 30, Figure 1 In the embodiment of the production and assembly of the contact assembly a shown in the figure, the part is a trip bolt a3, and one trip bolt a3 needs to be riveted with two shafts a4. Figure 11 In the embodiment, the shaft riveting machine 30 may also have two clamping mechanisms 3, and the clamps 31 of the two clamping mechanisms 3 are respectively located on both sides of the material feeding track 116, so that when one clamping mechanism 3 clamps one side of a shaft a4 of a release bolt a3, the other clamping mechanism 3 clamps the other side of another shaft a4 of another release bolt a3. For example,Figure 11 The squeezing mechanism 3 on the left side in the middle can squeeze the lower side of the shaft rod a4 on the left side of the release bolt a3, and the squeezing mechanism 3 on the right side can squeeze the upper side of the shaft rod a4 on the right side of the release bolt a3.

[0169] Correspondingly, the riveting machine 30 may further include two pressing mechanisms 4. The second pressing rods 421 of the two pressing mechanisms 4 are respectively located on both sides of the material feeding track 116, so that when one pressing mechanism 4 presses one side of a shaft rod a4 of a release bolt a3, the other pressing mechanism 4 presses the other side of the other shaft rod a4 of the other release bolt a3. As Figure 11 shown in, the pressing mechanism 4 on the left side in the middle can press the lower side of the shaft rod a4 on the left side of the release bolt a3, and the pressing mechanism 4 on the right side can press the upper side of the shaft rod a4 on the right side of the release bolt a3.

[0170] The following combines Figure 13 and Figure 14 to make an exemplary description of the clamp 31 of the squeezing mechanism 3 shown in Figure 11 . The clamp 31 includes a fixed seat 313, a pair of clamp legs 311, a pair of first springs 3161, a wedge block 315 and a first driving device 317. Among them, there is a receiving groove 3131 extending along its length direction inside the fixed seat 313, and a pair of first pin shafts 314 pass through the receiving groove 3131 and are arranged on the fixed seat 313.

[0171] Referring to Figure 14 , a clamping piece 312 is respectively connected to the heads of a pair of clamp legs 311 relatively, and a clamping opening 3121 is formed between the opposite sides of the pair of clamping pieces 312. And, Figure 13As can be seen in the figure, the opposite sides of the tail of the pair of pliers legs 311 are inclined to form a wedge-shaped opening 3111. The tail of the pair of pliers legs 311 and most of the body extend into the receiving slot 3131, and the head of the pliers legs 311 extends out of the receiving slot 3131; the position near the head of the pair of pliers legs 311 is respectively hinged on a first pin shaft 314, and when the pliers legs 311 rotate around their corresponding first pin shaft 314, the two clips 312 on the pair of pliers legs 311 are opened and closed. A pair of first springs 3161 are arranged in a pair of mounting holes of the fixed seat 313 and near the tail of the pliers legs 311, and one end of the first spring 3161 is against the back of the pair of pliers legs 311, and is arranged so that its elastic restoring force can make the wedge-shaped opening 3111 smaller and the two clips 312 open. A wedge block 315 is slidably disposed in the receiving groove 3131 of the fixed seat 313, and a wedge portion 3151 is formed on the side of the wedge-shaped opening 3111 of the pair of pliers 311, and when the wedge portion 3151 extends into the wedge-shaped opening 3111, the wedge-shaped opening 3111 is opened and the two clamps 312 are closed. The housing of the first driving device 317 is connected to the fixed seat 313, and the telescopic end 3171 of the first driving device 317 is connected to the side of the wedge block 315 facing away from the wedge portion 3151, and drives the wedge block 315 to slide along the receiving groove 3131.

[0172] In this embodiment, when the shaft a4 has been inserted into the jaws 3121 of the pair of clamps 312, when the first driving device 317 drives the wedge block 315 to move toward the clamp legs 311, the wedge-shaped openings 3111 of the pair of clamp legs 311 are opened and the clamps 312 disposed on the clamp legs 311 are closed, so as to clamp and press the shaft a4 to form a transverse protrusion. After the wedge block 315 moves away from the wedge-shaped openings 3111 of the pair of clamp legs 311, the pair of clamp legs 311 move under the elastic restoring force of the first spring 3161, the wedge-shaped openings 3111 become smaller and the pair of clamps 312 are opened, so as to allow the shaft a4 to be inserted into the jaws 3121 of the pair of clamps 312 before the next clamping of the shaft a4.

[0173] A mounting hole for the first spring 3161 can be formed in the following manner: a through hole is provided on the fixing seat 313, and a baffle 3132 is connected to the outer wall of the fixing seat 313 to shield the outer end of the through hole so that the other end of the first spring 3161 can be pressed against it. In this way, one end of the first spring 3161 can be pressed against the back of the pliers leg 311 and exert a squeezing effect on the pliers leg 311.

[0174] Preferably, refer to Figure 13 The fixing seat 313 may also be provided with a pair of limiting openings 3133, which are arranged opposite to each other and are both connected to the receiving groove 3131. In addition, both ends of the wedge block 315 may extend into the limiting openings 3133 and slide along the limiting openings 3133 to limit the sliding range of the wedge block 315.

[0175] Preferably, with reference to Figure 13 , the clamp 31 may further include a pair of second springs 3162. One second spring 3162 is respectively disposed in one limit port 3133. One end of the second spring 3162 abuts against the wedge block 315 and the other end abuts against the inner wall of the limit port 3133. The second spring 3162 is arranged such that its elastic restoring force can make the wedge block 315 away from the wedge-shaped opening 3111. Thus, when the telescopic end 3171 of the first driving device 317 retracts, the wedge block 315 can automatically reset by using the elastic restoring force of the second spring 3162. In this case, the mobile end of the first driving device 317 only needs to abut against the back surface of the wedge block 315 without connecting to the wedge block 315. For example, a positioning groove may be provided on the wedge block 315, and one end of the second spring 3162 may extend into the positioning groove to fix the position of the second spring 3162. In addition, a positioning post may also be provided on the wedge block 315, and one end of the second spring 3162 may also be sleeved on the positioning post to achieve fixation.

[0176] In the automated production process of this embodiment, a punching device 5 for realizing the automation of punching the second strip b, as Figure 15 shown, the punching device 5 includes a second machine base 51, a force arm 52, a mold 53 and a punching cylinder 54. The second machine base 51 includes a second fixing plate 511 and a support plate 512 provided on the second fixing plate 511. The force arm 52 is hinged to the top end of the support plate 512 through a second pin shaft 521. The mold 53 includes an upper die set and a lower die set. The top end of the upper die set is hinged to the first end of the force arm 52. The moving rod of the punching cylinder 54 is hinged to the second end of the force arm 52 to drive the force arm 52 to swing around the second pin shaft 521 and drive the upper die 53 to move up and down to cut the target finished product from the second strip b.

[0177] The punching device 5 is used to punch the second strip b sent by the strip conveying system 91. The punching device 5 includes a second machine base 51, a force arm 52, a mold 53 and a punching cylinder 54. The second machine base 51 includes a second fixing plate 511 and a support plate 512 provided on the second fixing plate 511. The force arm 52 is hinged to the top end of the support plate 512 through a second pin shaft 521. The mold 53 includes an upper die set and a lower die set; the top end of the upper die set is hinged to the first end of the force arm 52, and a punching knife is provided in the upper die set, and the punching knife can extend out from the bottom surface of the upper die set; the top surface of the lower die set faces the upper die set and can support the second strip b, and a first punching hole for the punch head of the punching knife to extend into is provided on the lower die set. The moving rod of the punching cylinder 54 is hinged to the second end of the force arm 52 to drive the force arm 52 to swing around its second pin shaft 521 and drive the upper die 53 to move up and down to realize the punching of the second strip b.

[0178] As can be seen from the above solution, after the second conveying device 14 conveys the second strip b forward by a second distance, the piston of the punching cylinder 54 extends and can drive the upper die set to move downward. At the same time, the punching knife in the upper die set can punch the second strip b carried on the lower die set. Also, after the punching work is completed, the piston of the punching cylinder 54 retracts and can drive the upper die set to move upward and away from the second strip b. At this time, the strip conveying system 91 can convey the second strip b forward by the next second distance for the punching device 5 to punch at a new position on the second strip b, which is conducive to realizing the automation of punching the second strip b.

[0179] In a preferred embodiment, the punching cylinder 54 of the punching device 5 can be controlled by a controller. Exemplarily, the cylinder barrel and the piston of the punching cylinder 54 are both non-magnetic, and the punching cylinder 54 further includes a permanent magnet ring, a magnetic switch, and a solenoid valve. The permanent magnet ring is coaxially sleeved on the piston. The magnetic switch is arranged on the cylinder barrel, and the magnetic switch is arranged such that when the piston moves to a position where it conducts, the punching knife can complete the punching of the second strip b. The solenoid valve is connected to the air path of the punching cylinder 54 to control the extension and retraction of the piston. Among them, the magnetic switch conducts due to the magnetic force of the permanent magnet ring.

[0180] Preferably, the punching device 5 further includes a controller, and the controller is signal-connected to the magnetic switch and the solenoid valve. Thus, when the controller receives a signal that the second conveying device 14 conveys the second strip b forward by a second distance, the controller controls the solenoid valve to make the piston of the punching cylinder 54 extend until the magnetic switch conducts and then stops extending. Subsequently, the controller controls the solenoid valve to make the piston of the punching cylinder 54 retract so that the upper die set and the punching knife leave the second strip b.

[0181] In a preferred embodiment of the punching device 5 provided by the present invention, the support plate 512 passes through the second fixing plate 511, and the lower end of the support plate 512 is hinged to the bottom end of the punching cylinder 54. The punching device 5 further includes at least one reinforcing plate. The bottom surface of the reinforcing plate is connected to the second fixing plate 511, and its side surface is connected to the support plate 512 to connect the support plate 512 to the second fixing plate 511. Thus, the punching device 5 can be integrally arranged to facilitate the use of the punching device 5.

[0182] In a preferred embodiment of the punching device 5 provided by the present invention, the force arm 52 is bent at the position where the second pin shaft 521 is located so that both ends of it extend obliquely downward. Thus, the length required for the connection between the upper die set and the force arm 52 and the length required for the connection between the punching cylinder 54 and the force arm 52 can be reduced, making it more convenient for the force arm 52 to be connected to the upper die set and the punching cylinder 54, and making a better torque formed during the working process.

[0183] In a preferred embodiment of the punching device 5 provided by the present invention, the distance between the die 53 and the second pin shaft 521 is shorter than the distance between the punching cylinder 54 and the second pin shaft 521. Thus, according to the lever principle, it is more labor-saving for the punching cylinder 54 to drive the upper die set to move up and down, which can reduce the fixed pressure requirement and failure rate of the punching cylinder 54.

[0184] In a preferred embodiment of the punching device 5 provided by the present invention, the punching device 5 further includes at least two guide posts. One end of the guide post is fixed to one of the upper die set and the lower die set, and the other end passes through the other of the upper die set and the lower die set. Wherein, the aperture of the hinge hole at the top end of the upper die set is larger than the diameter of the hinge shaft passing through it. Thus, it can guide the movement of the upper die set and maintain the punching accuracy of the punching knife.

[0185] In a preferred embodiment of the punching device 5 provided by the present invention, the upper die set includes at least one connecting plate, one pressing plate, at least one pull rod and a spring. The connecting plate is above and close to the force arm 52, and one end of the punching knife is connected to the connecting plate. The bottom surface of the pressing plate faces the lower die set, and a second punching hole for the punch head of the punching knife to extend out is provided thereon. One end of the pull rod is fixed to the connecting plate, and the end of the pull rod passes through the pressing plate and supports the pressing plate. The spring is coaxially sleeved on the pull rod, and the two axial ends of the spring respectively abut between the opposite surfaces of the connecting plate and the pressing plate.

[0186] In this embodiment, when the upper die set descends, the pressing plate first presses the vicinity of the cutting position of the second strip b, and then the connecting plate continues to move down and the spring is compressed. During this process, the punching knife cuts the second strip b. Thus, after pressing the second strip b near the cutting position and then cutting the second strip b, the pressing and cutting steps are separated, which is beneficial to improving the cutting effect. Thereafter, during the ascending process of the upper die set, the connecting plate rises first, the spring restores, and then the pull rod pulls the pressing plate away from the second strip b.

[0187] Combined Figures 1 to 16 With the above, the control process of the automatic connection system in this embodiment will be described globally. The automatic connection system includes a controller 6, and a second conveying device 14, a first conveying device 11, a set of punching and transfer integrated machine 1, a set of shaft-piercing machine 2, a set of riveting shaft machine 30 and a punching device 5 that are signal-connected to the controller 6.

[0188] Among them, the second conveying device 14 conveys the second strip b placed on its feeding track 116. An element is provided on the second strip b at every second distance. The first conveying device 11 conveys the first strip c along a direction parallel to the second strip b. A part is provided on the first strip c at every first distance. The punching, transferring and integrating machine 1 can punch the parts conveyed by the first conveying device 11 to its blanking port in sequence, and transfer a previously cut-off part to a predetermined position connectable to the element on the second strip b. The shaft-passing machine 2 includes a machine table 211 and at least one shaft-passing assembly 21 provided on the machine table 211; the shaft-passing assembly 21 is used to pass a shaft rod a4 through the shaft-passing holes on the element and the part. The shaft-riveting machine 30 is used to rivet the shaft rod a4 to the part to connect the element and the part together to form a new target finished product. The punching device 5 is used to cut off a target finished product from the second strip b. Among them, the shaft-passing machine 2, the shaft-riveting machine 30 and the punching device 5 are arranged at integer multiples of the second distance in sequence along the downstream direction of the second conveying device 14. And, the controller 6 is configured to:

[0189] S1. First, control the second conveying device 14 to convey the second strip b forward by a second distance. After receiving the transmission completion signal that the second strip b has been conveyed forward by a second distance, the controller 6 is configured to control to simultaneously complete the following operations:

[0190] S2. Control the first conveying device 11 to convey the first strip c forward by a first distance.

[0191] S3. Control the punching, transferring and integrating machine 1 to cut off a part on the first strip c.

[0192] S4. Control the punching, transferring and integrating machine 1 to transport a previously cut-off part to a predetermined position connectable to the element on the second strip b.

[0193] S5. Control the shaft-passing machine 2 to pass the shaft rod a4 through the shaft-passing holes on the element and the part.

[0194] S6. Control the shaft-riveting machine 30 to rivet the shaft rod a4 that has been passed through and connected before the current conveyance of the second strip b to the part, so as to connect the element and the part together to form a new target finished product.

[0195] S7. Control the punching device 5 to cut off a target finished product formed before the current conveyance of the second strip b from the second strip b.

[0196] S8. After receiving the feedback signal indicating that the above actions of the first conveying device 11, the punching, transferring and integrating machine 1, the shaft-passing machine 2, the shaft-riveting machine 30 and the punching device 5 have all been completed, control the second conveying device 14 to convey the second strip b forward by a second distance continuously.

[0197] The controller of the present application is in signal connection with the second conveying device 14, the first conveying device 11, a set of punching and transferring integrated machine 1, a set of shaft-piercing machines 2, a set of riveting shaft machines 30 and a punching device 5 of the automatic connection system, and is used to realize the automatic control of the automatic connection system. During the operation of the automatic connection system, after the second conveying device 14 conveys the second strip b and the bracket a1 thereon forward by a second distance, it will stop. During the process of the second strip b stopping moving, the first conveying device 11 can supply the release bolt a3 to the punching and transferring integrated machine 1, and the punching and transferring integrated machine 1 will transfer a release bolt a3 to a predetermined position connectable to the bracket a1 on the second strip b, and then a shaft-piercing assembly 21 of the shaft-piercing machine 2 will pass a shaft rod a4 through the shaft-piercing holes on the bracket a1 and the release bolt a3. At the same time, the riveting shaft machine 30 downstream of the shaft-piercing machine 2 rivets the two shaft rods a4 and the release bolt a3 respectively to connect and form a contact component a. In addition, the punching device 5 downstream of the riveting shaft machine 30 cuts the contact component a from the second strip b. In this way, the automation of the production and assembly of the contact component a is realized, and the production efficiency of the contact component a can be improved.

[0198] In a preferred embodiment, the controller 6 is further in signal connection with a set of positioning devices 24.
