The first pushing mechanism and the second pushing mechanism have the same structure, as shown in fig. 8, the first pushing mechanism is located above the second pushing mechanism, each pushing mechanism includes a pushing member and a second driver connected to the pushing member, and the pushing members are driven by the second drivers to move toward or away from the corresponding first placing cavity c115 or second placing cavity c 22. The second driver may be selected as a cylinder having a telescopic shaft extending in the first direction.

The pushing component is a plate, for example, the pushing component includes a plate c911 connected to the second driver, and a plurality of pushing strips c912 arranged at a side end of the plate c911 opposite to the second driver, the pushing strips c912 are in one-to-one correspondence with the respective placing cavities, and under the driving of the second driver, the pushing strips c912 can extend into or withdraw from the respective placing cavities, so as to realize the pushing action on the workpiece in the placing cavities. For example, when there are two first placing cavities c115, there are two corresponding pushing bars c912 on the first pushing mechanism. When there are two second placing chambers c22, there are two pushing bars c912 of the corresponding second pushing mechanism. As a deformation, the pushing mechanism can be in other structures besides the above structure, for example, the pushing mechanism is a telescopic cylinder, and a telescopic shaft of the cylinder directly extends into the corresponding placing cavity to push the corresponding workpiece.

In addition, as shown in fig. 1, the copper sheet discharging device further comprises a conveying mechanism arranged on a discharging port of the discharging bin c71, for example, the conveying mechanism is a belt conveyor c72, a discharging transition bin is arranged at the front end of the belt conveyor c72, and the second assembly formed by assembling screws and copper sheets in the discharging bin c71 can be conveniently transferred to the next process at any time. As a modification, the conveying mechanism may be other conventional conveying mechanisms other than the belt conveyor.

A material receiving mechanism which is telescopic and used for receiving unqualified products is arranged above the conveying mechanism and below a discharge hole of the discharge bin c71, and the material receiving mechanism comprises a material receiving bin c73 and a first air cylinder which drives the material receiving bin c73 to do telescopic motion along the sliding direction of the first die seat c 1. Correspondingly, a torque sensor for detecting the torque of the electric screwdriver and a controller electrically connected with the sensor are arranged in the electric screwdriver, and the controller is electrically connected with the first cylinder. The controller controls the first cylinder to drive the material receiving bin c73 to extend or retract according to the detection signal of the torque sensor.

When the torque sensor detects that the torque is smaller than the preset torque, the screw and the copper sheet are not locked in place and are used as unqualified products; or the workpiece output from the discharge bin c71 is only a copper sheet, and is not an assembly of a screw and the copper sheet, at the moment, the controller controls the first cylinder to extend out, so that the receiving bin c73 extends out below the discharge port and above the belt, and unqualified products are received into the receiving bin c 73; if the detected torsion is greater than or equal to the preset value, and optimally equal to the preset value, it indicates that the screws and the copper sheets in the second placing cavity c22 are locked in place, the controller can drive the first cylinder to do retraction movement, so that the material receiving bin c73 is moved away from the upper side of the belt, and the assembly body of the screws and the copper sheets falling in the material discharging bin c71 directly falls on the belt to be conveyed away. Or, as a modification, the conveying mechanism and the receiving mechanism may not be provided, and the workpiece falling from the discharge port of the discharge bin is directly used as the feed port of the next process.

The screw and the gasket are assembled in advance to form a first combination, and the locking process of the locking device of the screw and the copper sheet in the embodiment is as follows:

first, the first discharging port of the first feeding mechanism c4 and the second discharging port of the second feeding mechanism c4 (on the right side of the fixed plate in fig. 4) respectively convey the first assembly and the copper sheets into the first placing cavity c115 and the second placing cavity c 22; wherein, the gasket in the first combination is lapped on the boss c114 of the first placing cavity c115, the copper sheet is lapped on the clamping groove c21 in the second placing cavity c22, and the two die seats are in a material receiving state in the process;

secondly, the first mold seat slides towards the direction close to the second mold seat (the back side slides in fig. 4), the blocking part c12 on the first mold seat c1 is in sliding contact with the first blanking port, the clamping assembly c32 is driven by the first lifting mechanism to move up or down, so that the second through hole c113 of the first placing cavity c115 slides until being level and communicated with the second opening of the clamping cavity of the clamping assembly c32 in the horizontal direction, and the first mold seat c1 is in a material blocking state in the sliding process;

then, the first pushing mechanism performs an extending motion (extends leftwards in fig. 4), so that the pushing strips c912 are embedded into the first placing cavity c115 through the first through hole c112 in a one-to-one correspondence manner, a pushing force towards the clamping cavity is applied to the gasket, the first assembly is pushed into the clamping cavity through the second through hole c113 and abuts against the baffle c324, the two clamping heads clamp the two ends of the gasket under the biasing force of the two elastic members, and the first pushing mechanism performs a retracting motion and reset (retracts rightwards in fig. 4); the first die holder c1 is slid reversely and restored to the initial position (slid to the front side in fig. 4), and the first placing cavity c115 is again in butt communication with the first blanking port, so that the first placing cavity c115 is again in a material receiving state;

simultaneously or afterwards, the second die seat c2 slides towards the direction close to the first die seat c1 (slides towards the front side in fig. 4), so that the top notch c111 of the second placing cavity c22 is in direct communication with the first opening at the bottom of the clamping cavity, and the screw part of the screw is in direct communication with the inner hole of the copper sheet; the blocking part c12 on the second die seat c2 is in sliding abutting joint with the second feed opening, and the second die seat c2 is in a blocking state in the sliding process; the clamping component c32 moves downwards under the drive of the first lifting mechanism, so that the screw rod part extends into the inner hole of the copper sheet;

the second lifting mechanism drives the screwdriver to do descending motion, the bottom of the screwdriver penetrates through the abdicating channel c325 and extends into the clamping cavity, downward acting force is applied to the screw, the two chucks move towards the directions away from each other, the clamping force on the gasket is relieved, the clamping assembly moves upwards to enable the clamping assembly to be completely separated from a first assembly of the screw and the gasket, and the screw is locked on the copper sheet by the first assembly under the rotation of the screwdriver;

then, the electric screwdriver ascends, at the moment, the second pushing mechanism stretches out (stretches out to the left side in fig. 4), the pushing strips c912 on the second pushing mechanism correspondingly stretch into the second placing cavity c22 through the first through hole one by one, a second combination formed by locking the screws and the copper sheets is pushed forwards and is pushed into the transition placing cavity c61 through the second through hole to be further pushed into the discharging bin c71, and the second combination falls on the belt conveyor c72 through the discharging bin c71 and is finally conveyed to the next station;

finally, the second pushing mechanism retracts (the right side in fig. 4 retracts), and the pushing strip exits the second placing cavity c22 and is reset to the initial position; the second die seat c2 slides reversely (slides to the rear side in fig. 4), and is reset to the initial position, so that the second placing cavity c22 is in butt joint communication with the second feed opening again, and the second die seat c2 is in a material receiving state; and by parity of reasoning, the next screw and copper sheet are locked and assembled.

In the locking device for the screw and the copper sheet in the embodiment, in the whole locking process, the feeding process of the screw and the copper sheet is realized by adopting the first feeding mechanism c4 and the second feeding mechanism c4, manual feeding is not needed, and the screw and the copper sheet are ensured to be placed in place in the first placing cavity c115 and the second placing cavity c22 respectively; when the screws are transferred onto the copper sheets, the screws are transferred by adopting the first pushing mechanism, the screw rods of the screws are ensured to penetrate through the inner holes of the copper sheets in a right-to-ground manner under the lifting motion of the clamping assembly, the screws and the copper sheets are locked in place by adopting the automatic rotation of the screwdriver to form a second assembly, the second assembly locked in place is pushed to the discharge bin c71 by the second pushing mechanism and finally conveyed to the next procedure by the belt conveyor, so that the locking device is high in working efficiency and the yield of the locked screws and copper sheets is high.

As a first alternative of the above embodiment, the first lifting mechanism and the second lifting mechanism may be independently provided, and do not need to share one guide rail.

As the deformation, when two chucks of the clamping assembly adopt other structures to realize automatic mutual away movement, for example, through independently setting up a cylinder, the telescopic motion through the cylinder drives two chucks to do mutual away movement, the screw part does not need to be locked and the screw part is arranged in the channel of stepping down, the screw part and the clamping assembly can be completely independently arranged, and the channel of stepping down also does not need to be arranged on the clamping assembly.

As a second alternative implementation manner of the above embodiment, the projections of the first mold seat and the second mold seat in the horizontal direction may overlap but be staggered in height, the projections of the first placing cavity and the second placing cavity in the horizontal direction may overlap, at this time, the above-mentioned first pushing mechanism is not required to be provided, the transfer mechanism may directly clamp and place the workpiece in the first placing cavity in the second placing cavity by using the clamping assembly, at this time, the two chucks that need the clamping assembly may extend into the first placing cavity to clamp the workpiece, and the first pushing mechanism is not required to be provided.

As a further modification, the positions of the first mold seat and the second mold seat in the horizontal or vertical direction are not limited, and the first mold seat and the second mold seat can also be arranged on the base without sliding; or, the first mold seat and the second mold seat are not arranged, the first placing cavity and the second placing cavity are directly arranged on the base frame, and the positions of the two placing cavities on the base frame are fixed. Only need transfer mechanism can place reciprocating motion between the chamber at first placing the chamber and the second, and place the breach in chamber and do concertina movement along the second, just can place the work piece of intracavity with first and transfer to the second and place the intracavity to through concertina movement, make the screw rod part of screw pack in the hole of sheet. For example, the transfer mechanism includes a robot arm, and a robot arm fixed to the robot arm.

As the deformation, the first chamber of placing can only establish the top opening, does not set up foretell first opening and second opening, and feed mechanism directly places intracavity delivery screw and copper sheet to first chamber of placing and second from top opening department respectively, for example feed mechanism is equipped with moving mechanism alone, and after finishing the work piece on, moving mechanism drive feed mechanism moved away, avoids the top opening, is convenient for shift the work piece or subsequent locking. Or for example the feed mechanism is a robot arm that is movable in three dimensions. In addition, when the screw is not matched with the gasket, the nut of the screw can abut against the abutting position when the screw is placed in the first placing cavity.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
