In one embodiment, as shown in fig. 3, the positioning mechanism 700 includes a cylinder 710, a first jig 720, and a carrier 730.

A cylinder 710 is provided on the first driving mechanism for providing driving force to the entire positioning mechanism 700. The cylinder 710 may be a commercially available cylinder 710.

One end of the first fixture 720 is connected with the cylinder 710, and the other end is connected with the carrier 730. The first jig 720 may be provided with a groove, the carrier 730 is detachably disposed in the groove, and the shape of the groove may be matched with the size of the carrier 730.

In an embodiment, the first fixture 720 may be provided with a first positioning pin 721, the carrier 730 may be provided with a first positioning hole matched with the first positioning pin 721, and the carrier 730 may be positioned in cooperation with the first positioning pin 721 disposed on the first fixture 720 through the first positioning hole.

In an embodiment, the carrier 730 may further include a second positioning hole 732, where the second positioning hole 732 can be matched and positioned with a second positioning pin (not shown) of a second fixture on the shearing machine; the second jig can be disposed above the first jig 720. The second jig may be disposed on the adjusting device, and cooperate with the first jig 720 to position the carrier 730.

In the present embodiment, the number of the first positioning pins 721 and the number of the second positioning pins are two. In other embodiments, the number of the first positioning pins 721 and the second positioning pins may not be limited, and may be other plural.

In order to simplify the positioning process, the structural dimensions of each positioning mechanism 700 are kept uniform. In particular, the shape and position of carrier 730 in each positioning mechanism 700 are the same. When the positioning mechanism 700 moves intermittently along with the first driving mechanism, the carrier 730 in the lower positioning mechanism 700 can move to the working position of the carrier 730 in the upper positioning mechanism 700 and then stop moving. The working position includes the position, direction, and location of the positioning holes on the carrier 730 where the product is placed in the carrier 730.

In an embodiment, the first fixture 720 includes a first movement mechanism, which is respectively connected to the air cylinder 710 and the carrier 730, and the air cylinder 710 drives the first movement mechanism to move, so as to drive the carrier 730 to move, so as to realize pin hole positioning switching between the carrier 730 and the first positioning pin 721 and the second positioning pin. The first movement mechanism may include a push rod 722 coupled to the cylinder 710 and a push plate 723 coupled to the push rod 722, with a carrier 730 disposed on the push plate 723. The cylinder 710 pushes the push rod 722 to move, and the push rod 722 pushes the push plate 723 to move, so as to drive the carrier 730 to move, thereby realizing the positioning switching of the positioning pin and the positioning hole on the carrier 730.

In order to ensure that the first movement mechanism reciprocates smoothly, the first fixture 720 may further include a return mechanism 724, where the return mechanism 724 is configured to provide a restoring force for the first movement mechanism. The return mechanism 724 is preferably a spring structure. The return mechanism 724 may include a plurality of compression springs that may be placed over the thin rod on the first jig 720.

When the first movement mechanism pushes the carrier 730 to move, the limiting plate 726 on the first jig 720 abuts against the limiting block on the second jig, so as to limit the first movement mechanism to move continuously and improve the positioning accuracy.

In one embodiment, a sensor (not shown) for sensing pin hole positioning may be disposed on the first fixture 720. Specifically, the sensor can be placed on the first limiting pin and the first limiting hole, and also can be placed on the second limiting pin and the limiting hole, so that whether the pin hole is positioned or not is judged through the sensor, and the positioning is more accurate. In addition, the next work can be automatically carried out through the induction signals emitted by the sensor, and the degree of automation is higher.

By adding the first driving mechanism and the controller 900, the intermittent motion of the positioning mechanism 700 is realized, so that after the position of the first positioning mechanism 700 is adjusted, the welding of the first product is performed, after the welding is finished, the first driving mechanism 800 and the controller 900 can control the positioning mechanism 700 to move together, so that the second positioning mechanism 700 stops moving after moving to the working position of the first positioning mechanism 700, the processing of the second product is continued, and so on. Therefore, the automatic positioning device only needs to perform one-time positioning position adjustment, and does not need to repeat the position adjustment for a plurality of times, so that the working procedure is simplified, and the working efficiency is improved.

As shown in fig. 6 and 7, the automatic welding integrated system may further include a position adjustment mechanism 500 disposed on the first stand 100, for adjusting a welding position of the conductive rod on the workpiece to be welded, wherein the shearing mechanism 300 may pass through the middle of the position adjustment mechanism 500, and a window capable of vertically observing the shearing mechanism 300 to perform a shearing action is disposed in the position adjustment mechanism 500.

Specifically, the first direction may be an X-axis direction, and the second direction may be a Y-axis direction. In other embodiments, the first direction and the second direction may be set in other directions, which is only required to be satisfied to effectively adjust the welding position.

In one embodiment, the elastic member 530 is a fastening screw provided on the movable mechanism 510 for fastening and unfastening the movable mechanism 510. The elastic member 530 may be used to adjust the degree of freedom of movement of the movable mechanism 510 in the first direction and the second direction. The number of the elastic members 530 is not limited, and may be 1 or more; in the present embodiment, the number of elastic members 530 is 2. When the movable mechanism 510 needs to be adjusted, the fastening screw can be loosened, and the movable mechanism 510 has no limitation on the freedom degree, and the movable mechanism 510 can be correspondingly adjusted in position through the first adjusting mechanism and the second adjusting mechanism.

The number of the first adjusting mechanisms and the second adjusting mechanisms is at least 1. In one embodiment, among the first and second adjusting mechanisms, one adjusting mechanism 520 has a number of 2 and the other adjusting mechanism 520 has a number of 1. Of course, in other embodiments, the number of first and second adjustment mechanisms may be other numbers that satisfy the condition.

In one embodiment, the adjustment mechanism may include a micrometer assembly. Specifically, when the number of the first adjusting mechanisms is 1 and the number of the second adjusting mechanisms is 2, the first adjusting mechanisms include a first thousandth head assembly 521 and a first limiting member 522, the first limiting member 522 is used for limiting a moving distance of the moving mechanism 510 along the first direction, and the first thousandth head assembly 521 and the first limiting member 522 are symmetrically disposed on two sides of the moving mechanism 510. The added first limiting member 522 can limit the moving distance of the movable mechanism 510 along the first direction, so as to avoid overregulation. The first limiting member 522 may be mounted on the jig body, and a certain distance may be provided between the first limiting member 522 and the movable mechanism 510, so that when the first limiting member 522 abuts against the movable mechanism 510, the movable mechanism 510 cannot move continuously along the first direction.

Unlike the first adjustment mechanism described above, the second adjustment mechanism may include a second micrometer head assembly 523 and a third micrometer head assembly 524, and are disposed at the same or opposite sides of the movable mechanism 510 at intervals. In the present embodiment, the second micrometer head assembly 523 and the third micrometer head assembly 524 are disposed at an interval on the same side of the movable mechanism 510. In other embodiments, both may be disposed on opposite sides at intervals.

The first, second and third head assemblies 521, 523, 524 may each include a split head and a push rod. One end of the push rod is connected with the micrometer head, and the other end of the push rod is propped against the movable mechanism 510.

In an embodiment, the first adjusting mechanism and the second adjusting mechanism may be fixed on the jig body through the first connecting member 540. Namely, the first thousandth head assembly 521, the second thousandth head assembly 523 and the third thousandth head assembly 524 can be fixed on the jig body through the first connecting piece 540. In this embodiment, the first connecting member 540 may be an L-shaped connecting member, and the L-shaped connecting member is fixed on the jig body. Specifically, the first thousandth head assembly 521 and the second thousandth head assembly 523 may be respectively disposed on two sides of an L-shaped connecting piece, which are perpendicular to each other; likewise, the third thousandth head assembly 524 and the first stop 522 may be disposed on two sides of the other L-shaped connector, respectively, that are perpendicular to each other.

In this embodiment, the movable mechanism 510 may include an upper movable member and a lower movable member connected to the upper movable member, and the shearing mechanism 300 is disposed between the upper movable member and the lower movable member. The upper movable member and the lower movable member are connected by a first connecting member 540. A space is left between the upper and lower movable members, which can accommodate the cutter head of the shearing mechanism 300. The upper movable member may be a movable frame with a window, and the lower movable member may be a plate with a first opening. Through which the shearing action of the shearing mechanism 300 and the first opening below through which the workpiece to be welded can be observed can be viewed vertically. The back of the lower movable part can be provided with a second locating pin (not shown), the second locating pin is matched with a corresponding second locating hole on a carrier for placing a workpiece to be welded, and the welding position can be quickly adjusted and positioned through pin hole matching. In addition, after the second positioning pin is matched with the positioning hole, an inductor can be arranged on the welding machine, whether the pin hole is matched in place or not is sensed by the inductor, and if the position of the carrier is detected to be a preset correct position, the welding mechanism is triggered to perform welding operation.

In one embodiment, the movable frame is a U-shaped frame. In other embodiments, the movable frame may be a square frame or other polygonal frame or a special-shaped frame or other structure with an opening. In order to make the whole mechanism structure more compact, the U-shaped frame can be provided with an assembly step corresponding to the L-shaped connecting piece.

In an embodiment, the welding fixture may further include a first reset mechanism (not shown) and a second reset mechanism (not shown), where the first reset mechanism and the second reset mechanism are disposed on the movable mechanism 510, and the first reset mechanism and the second reset mechanism are used for moving the first adjusting mechanism and the second adjusting mechanism along opposite directions of the first direction and the second direction, respectively. Further, the first return mechanism and the second return mechanism each include a return spring and a return member that constrains the return spring. The return member may be a stop or a plate having an opening or slot capable of receiving a return spring.

Thus, when the position of the movable mechanism 510 is adjusted, the movable mechanism 510 moves and compresses the return springs on the first and second return mechanisms, and the return springs accumulate elastic potential energy; when the position adjustment is too large, the first adjusting mechanism and the second adjusting mechanism are adjusted to move along the opposite directions of the first direction and the second direction respectively, at this time, the pushing rods on the first adjusting mechanism and the second adjusting mechanism do not prop against the movable mechanism 510, and the movable mechanism 510 moves along the opposite directions of the first direction and the second direction under the action of the restoring force of the compressed restoring spring, so that readjustment and restoration of the movable mechanism 510 are realized.

As shown in fig. 1, in one embodiment, the welding mechanism 200 further includes a second driving mechanism 220 disposed on the first stand 100, and having a driving member and a hook member, wherein two ends of the hook member are respectively connected to the driving member and the impact member 210, and the driving member can drive the hook member to move up and down, so as to drive the impact member 210 to move up and down. The second driving member may be a common driving member such as a cylinder, and the hook member may be a member with a hook portion, and the hook portion hooks the impact member 210 to move the impact member 210. The second driving mechanism 220 can realize accurate control of the movement of the impact member 200, and improves the welding effect.

During welding, the impact piece 210 bends and descends to drive the conductive rod to descend for welding, and after welding, the impact piece 210 is reset and simultaneously the needle tube 442 is driven to reset. The impact member 210 is preferably made of steel with good elasticity, and can rapidly move up and down under the action of external force. When the impact member 210 moves up and down, the guide block 441 connected with the impact member 210 is driven to move up and down, so that the needle tube 442 connected with the guide block 441 drives the conductive rod in the needle tube 442 to move up and down and contact with the work surface to be welded, and corresponding electrodes are arranged on the conductive rod and the work piece to be welded.

In one embodiment, the first housing 100 may include an upper housing and a lower housing with a sliding rail assembly therebetween. The upper stand can slide relative to the lower stand so as to avoid interference of the front end extending part of the welding machine on rotation or movement of the feeding machine.

In one embodiment, the welder further includes an inductor (not shown) that can detect whether the position of the product on the feeder is accurately positioned. When the position of the product is detected to be correct, the welding mechanism can be triggered to move for welding.

In an embodiment, the workflow of the integrated system may include: the mechanical arm (not shown) places the product in the carrier, and the motor drives the second mounting plate to move so as to drive the jig placed on the second mounting plate to move, and then drive the carrier on the first jig to move. And stopping moving after the carrier moves to a preset position at the lower end of the welding machine. The upper machine seat on the first machine seat moves towards the carrier along the guide rail, and after the upper machine seat reaches a set position, the first driving mechanism at the lower end of the carrier is jacked up, so that the positioning holes on the surface of the carrier are matched with the positioning pins on the welding machine, at the moment, the sensor can sense that the relative position of a product is correct, then the welding jig is triggered to work, and after the welding is finished, the carrier descends.

As shown in fig. 4, the shearing mechanism has a cutter assembly 310 and a third driving mechanism 320 connected to the cutter assembly 310, the third driving mechanism 320 controlling the left and right cutters in the cutter assembly 310 to move toward or away from each other.

In one embodiment, when the third drive mechanism 320 controls the left and right cutters in the cutter assembly 310 to move toward each other, the minimum spacing d between the cutter head vertices of the left and right cutters satisfies 0.01mm < d < 0.03mm. In one embodiment, the minimum distance d is about 0.02mm. In other embodiments, the minimum spacing may be other values within the ranges described above.

Further, the left cutter and the right cutter comprise a cutter head, a cutter body and a cutter tail which are sequentially connected.

Because the tool bits of the left tool bit and the right tool bit move in opposite directions to realize flattening of the transmission rod, the tool bit is damaged in order to reduce collision among the tool bits, the shearing effect is affected, and the tool bit can be polished to be a blunt port. Preferably, the cutter heads are all conical blunt cutter heads. The cutter tail is connected with the driving mechanism, so that the acting force of the driving mechanism on the cutter is balanced, the cross-sectional area of the cutter tail connected with the driving mechanism can be increased, namely, the cross-sectional area of the cutter tail can be larger than the cross-sectional area of the cutter body, and likewise, the cross-sectional area of the cutter body can be larger than the cross-sectional area of the cutter head.

In one embodiment, the left and right cutters are of square overall construction. Specifically, the tool bit of left and right cutter is toper and conical top dorsad blade setting, and the blade setting is between tool bit and tail and is little square structure, and the tail is close to actuating mechanism setting and is big square structure. In addition, the cutter heads of the left and right cutters can be provided with notches which are oppositely arranged, and the end parts of the cutter heads are polished into an arc shape. In other embodiments, the left and right cutters may be other shapes, so long as the cutters are capable of performing a shearing operation on the guide bar.

In one embodiment, the left and right cutters may be uniformly sized and shaped for simplifying the machining and assembly process. In other embodiments, the left and right cutters may be sized and shaped differently, so long as the cutters meet the shearing requirements described above. The left and right cutters may be made of high hardness steel.

In one embodiment, the third driving mechanism 320 may include a left cylinder and a right cylinder, which are connected to the tool tails of the left and right tools, respectively. The left and right cylinders may be fixedly installed on the first housing 100. The left and right cylinders are used for driving the left and right cutters to move in opposite directions or back to back directions respectively. The left and right cylinders can be common commercial products. In other embodiments, the driving mechanism may be a motor, an electric machine, or other commonly used driving mechanisms.

In one embodiment, the shearing mechanism 300 may further include a second connecting member 330, and the tail portions of the left and right cutters are connected to the driving mechanism through the second connecting member 330. The tool may be secured to the connection block by conventional fasteners. The second connector 330 may be a connection block matching the shape of the cutter tail, and the connection block may be any shape capable of fixing the cutter tail of a cutter, such as a flat plate shape, a U shape, etc.

Further, the shearing mechanism 300 may further comprise a limiting seat 340 disposed on the first housing 100, wherein the limiting seat 340 is used for limiting the movement direction of the cutter assembly 310, and the limiting seat 340 is provided with an open slot and a first channel and a second channel which are disposed opposite to each other, and the cutter heads of the left and right cutters in the cutter assembly 310 can respectively pass through the first channel and the second channel and can be gathered in the open slot, besides the cutter assembly 310 and the third driving mechanism 320 connected with the cutter assembly 310.

When the third driving mechanism 320 drives the left and right cutters in the cutter assembly 310 to reciprocate at the first and second passages, respectively, the line connecting the cutter head apexes of the left and right cutters is on the same straight line.

Specifically, the tool bits of the left and right tools can pass through the first and second passages, respectively, and can converge in the open slot. The open slot is equivalent to an observation port, through which the cutter head conditions of the left and right cutters can be clearly observed, and the cutters can be correspondingly adjusted according to the observation result. For easy assembly and processing, the limiting seat 340 may be preferably in an integrated structure, and the left and right cutters may be inserted into the limiting seat 340 at opposite sides thereof, respectively. In other embodiments, the limiting seat 340 may be a split structure, i.e. a left limiting seat 340 and a right limiting seat 340; at this time, the left and right cutters are respectively inserted into the left and right limiting seats 340 and 340 correspondingly, and the positions and the movement directions of the cutter heads of the left and right cutters are adjusted by adjusting the heights and the positions of the left and right limiting seats 340, so that the left and right cutters can meet the machining conditions of the shearing work.

The first and second channels are capable of allowing the left and right cutters to reciprocate slightly in the channels to perform a shearing operation on the guide rods. The first and second channels may be square channels, circular channels, or channels of other shapes. Preferably, the channel is adapted to the corresponding tool profile. The first channel and the second channel may be disposed in the middle of the limiting seat 340, so as to form a through hole structure channel. In addition, the first channel and the second channel may also be disposed at the bottom of the limiting seat 340, so as to form a channel with a groove structure.

When the driving mechanism drives the left cutter and the right cutter to do reciprocating motion at the first channel and the second channel respectively, the connecting lines of the cutter head vertexes of the left cutter and the right cutter are on the same straight line. Therefore, the left cutter and the right cutter can move along the shearing direction, and the problem that the conductive rod cannot be flattened smoothly due to deviation of the movement directions of the left cutter and the right cutter can be solved. In addition, because the cutter heads of the left cutter and the right cutter are oppositely arranged, in order to avoid damage caused by contact of the cutter heads, the cutter heads can not contact when the left cutter and the right cutter move oppositely, and the minimum distance d between the cutter head vertexes of the left cutter and the right cutter meets that d is more than or equal to 0.01mm and less than or equal to 0.03mm. In one embodiment, the minimum distance d is about 0.02mm. In other embodiments, the minimum spacing may be other values within the ranges described above.

In one embodiment, a second opening is formed in the bottom of the open slot, and the second opening is arranged below the converging position of the cutter heads of the left cutter and the right cutter. A jig for a workpiece to be welded can be placed below the second opening, and the condition of a conducting rod on the workpiece on the jig can be directly observed through the second opening; after the shearing work is finished, the movable jig can move downwards to take out the workpiece from the lower part of the shearing device, so that the situation that the workpiece is taken from the upper part to interfere the shearing device and the conducting rod above is avoided, and the actual operation is facilitated.
