TECHNICAL FIELD

[0001] The application relates to the field of moving spring manufacturing, in particular to a feeding and discharging system for a moving spring detection and adjustment device. BACKGROUND

[0002] A relay is used to control the connection or disconnection of a circuit by energizing an electromagnetic coil to attract an armature, so that the armature drives the moving spring to produce a certain bending to fit the static spring. Therefore, taking a moving spring as an example, referring to Figure 5 , the fixed segment 11 has a row of rivet points 12 formed on one side, the fixed segment 11 is integrally formed with an arc segment 13, the circumferential outer wall of the arc segment 13 is close to the rivet points 12, and the arc segment 13 is integrally formed with a deformation segment 14 on the side away from the fixed segment 11. The deformation segment 14 is provided with a contact head in contact with the static spring. When the inclination between the deformation segment 14 and the fixed segment 11 and the thickness of the deformation segment 14 are greatly different from the standard value, it will greatly affect the accuracy of the entire relay.

[0003] The existing moving spring detection and adjustment system and method with the publication number CN109870110A need to place the moving spring in the vertical direction on the corresponding supporting plate, and the fixed end of the moving spring is placed in the relay to be fixed by the positioning member, and then the end of the moving spring driven by the armature to bend in the relay is adjusted in inclination.

[0004] According to the related technology in the above, the moving spring needs to be placed manually, and after the detection and adjustment are completed, the moving spring is taken out and placed by manual operation. The feeding and discharging of the moving spring is relatively inconvenient, and it is difficult to improve the detection efficiency. SUMMARY

[0005] In order to improve the detection efficiency, the application provides a feeding and discharging system for a moving spring detection and adjustment device.

[0006] The feeding and discharging system for a moving spring detection and adjustment device provided by the application adopts the following technical scheme.

[0007] A feeding and discharging system for a moving spring detection and adjustment device, comprising a front conveying device for conveying the moving spring in a predetermined posture, a feeding device for clamping the moving spring conveyed to the position by the front conveying device and placing the moving spring into the moving spring detection and adjustment device, a discharging device for clamping the moving spring after detection and adjustment and moving away from the moving spring detection and adjustment device, and a rear conveying device for receiving the moving spring clamped by the discharging device and conveying the moving spring in a predetermined posture.

[0008] By adopting the above technical scheme, manual feeding and discharging of the moving spring is no longer needed, so as to improve the detection efficiency.

[0009] Optionally, the front conveying device comprises two front conveying belts which are in close proximity and are cyclically driven, and a plurality of clamping blocks are fixedly connected to the front conveying belts, one clamping block is arranged corresponding to each front conveying belt, and a distance sensor is arranged corresponding to the position between the two clamping blocks.

[0010] By adopting the above technical scheme, in the synchronous driving process of the two front conveying belts, the two clamping blocks in the same group can be driven to move synchronously, so that the moving spring piece can be driven to move forward between the two clamping blocks in the same group, and when the moving spring piece is removed, the moving spring piece is no longer directly opposite to the distance sensor, so that the distance value detected by the distance sensor changes, so that the external controller can clearly know that the moving spring piece is easy to be clamped away at this time, and the front conveying belt is controlled to drive until the next moving spring piece moves to the position directly opposite to the distance sensor, so that the moving spring piece can be continuously conveyed to the specified position for clamping by the feeding device.

[0011] Optionally, all the clamping blocks of one of the front conveying belts are fixedly connected with a limiting piece capable of abutting against the arc segment, and the limiting piece enables the fixed segment to enter between the two clamping blocks in the same group only when the arc segment is directly above the clamping blocks away from the limiting piece.

[0012] By adopting the above technical scheme, after the moving spring piece is inserted between the two clamping blocks, the orientation of the arc segment remains fixed, so as to ensure that the state of each moving spring piece is relatively consistent.

[0013] Optionally, the two clamping blocks in the same group are slidably connected with clamping blocks on the proximal sides, the clamping blocks are provided with clamping spring which is proximal to the two clamping blocks, and the two clamping blocks are formed with push inclined surfaces on the sides for the fixed segment to be inserted, and the two push inclined surfaces are arranged to abut against the fixed segment to force the two clamping blocks to move away from each other.

[0014] By adopting the above technical scheme, the fixed segment can be inserted between the two clamping blocks, and the insertion of the moving spring piece into the two clamping blocks can be simultaneously arranged for a plurality of clamping blocks, which helps to improve the feeding speed and facilitates the direct removal of the moving spring piece from between the two clamping blocks and the transfer of the moving spring piece.

[0015] Optionally, a point channel is formed on the side of the clamping block close to the feeding device, the point channel is connected with a plurality of branch channels connected to the push inclined surfaces, the number of the branch channels is less than the number of rivet points of the moving spring piece, each branch channel is arranged for one rivet point to enter, and the branch channel is formed with a point inclined surface at the opening of the push inclined surface, and the point inclined surface is arranged to abut against the rivet point.

[0016] By adopting the above technical scheme, when the clamping block abuts against the fixed segment, the rivet point is not easy to bear a large pressure, and the state of the moving spring piece between the two clamping blocks can also be kept stable, and a part of the rivet points enter the branch channels, so that the state of the moving spring piece between each group of clamping blocks can be better kept consistent.

[0017] Optionally, the clamping block is provided with a pressure sensor abutting the clamping spring away from the clamping block end, and the pressure sensor is assisted in judging the thickness of the moving spring sheet according to the pressure received.

[0018] By adopting the above technical scheme, when the thickness of the moving spring sheet is not up to standard, i.e. the thickness of the fixed end is not up to standard, the pressure received by the pressure sensor is also different, so that the moving spring sheet with unqualified thickness can be pre-identified, and it is not necessary to wait until the moving spring sheet is placed in the moving spring sheet detection and adjustment device for thickness detection, and the detection efficiency is higher.

[0019] Optionally, the feeding device comprises a horizontal rotation electric cylinder capable of moving the moving spring sheet to directly above the moving spring sheet detection and adjustment device, the horizontal rotation electric cylinder is fixedly connected with a shaft plate, the shaft plate is fixedly connected with a vertical rotation electric cylinder capable of adjusting the state of the moving spring sheet to facilitate placing into the moving spring sheet detection and adjustment device, the vertical rotation electric cylinder is fixedly connected with a linear electric cylinder moving the moving spring sheet, and the linear electric cylinder power rod is fixedly connected with an electric finger clamping the fixed section.

[0020] By adopting the above technical scheme, the electric finger clamps the part of the fixed section exposed to the two clamping blocks, then the linear electric cylinder moves the moving spring sheet away from the two clamping blocks, then the vertical rotation electric cylinder changes the state of the moving spring sheet from the fixed section and the deformation section with different heights to the state with the same height, and at the same time, the horizontal rotation electric cylinder transfers the moving spring sheet to directly above the moving spring sheet detection and adjustment device, and then the linear electric cylinder vertically lowers the moving spring sheet to the moving spring sheet detection and adjustment device for corresponding detection and adjustment.

[0021] Optionally, one jaw of the electric finger is formed with a jaw groove for part of the rivet point to enter.

[0022] By adopting the above technical scheme, when the electric finger clamps the fixed section, the jaw groove allows part of the rivet point to enter, reducing the pressure on the rivet point, and also allowing the rivet point to abut against the inner wall of the jaw groove when the linear electric cylinder moves the moving spring sheet away from the two clamping blocks, so as to provide sufficient external force to make the fixed section separate from the two clamping blocks.

[0023] Optionally, the rear conveying device comprises a rear conveying belt, the rear conveying belt is fixedly connected with a plurality of insert blocks for inserting the fixed section, each insert block is slidingly connected with an abutting block, the insert block is provided with an abutting block spring forcing the abutting block away from the fixed section, the abutting block exposed to the side of the insert block can abut against a long strip forcing the abutting block to abut against the fixed section, and the abutting block is formed with an abutting inclined surface corresponding to the conveying direction of the rear conveying belt and the side abutted by the long strip.

[0024] By adopting the technical scheme, in order to put the fixed section of the moving spring sheet into the insertion sheet block, the arc section needs to be clamped, and the deviation of the clamping position of the arc section is easy to cause the moving spring sheet to be slightly inclined as a whole, so the opening width of the insertion sheet block for the fixed section to enter is designed to be larger, so that the fixed section of the moving spring sheet in a certain inclined range can stably enter into the insertion sheet block, and then in the process of the insertion sheet block being driven by the rear conveying belt to move forward, the abutting surface will abut against the long strip, so that the abutting block keeps abutting against the fixed section, so that the state of the moving spring sheet in the insertion sheet block keeps consistent.

[0025] Optionally, the abutting block is provided with a block groove for the rivet point to enter, and a plurality of moving-out grooves are formed in the inner wall of the block groove and communicated to the outer wall of the abutting block for each rivet point to move out.

[0026] By adopting the technical scheme, the rivet point is not easy to bear excessive pressure, and it is also convenient to move the fixed section out of the insertion sheet block.

[0027] In summary, the present application has at least one of the following beneficial effects:

[0028] 1. Manual feeding and discharging of the moving spring sheet is no longer needed, so as to improve the detection efficiency;

[0029] 2. When the thickness of the moving spring sheet does not meet the standard, i.e. the thickness of the fixed end does not meet the standard, the pressure sensor will also bear different pressures, so as to pre-identify the moving spring sheet with unqualified thickness, and the moving spring sheet does not need to be placed in the moving spring sheet detection and adjustment device for thickness detection, so the detection efficiency is higher.

DETAILED DESCRIPTION

[0036] The application will be further described in detail below with reference to the accompanying drawings.

[0037] The embodiments of the application disclose a feeding and discharging system for a dynamic spring sheet detection and adjustment device. Figure 1 The feeding and discharging system comprises a front conveying device 1 and a feeding device 2 located at the same side of the dynamic spring sheet detection and adjustment device 15, and a discharging device 3 and a rear conveying device 4 installed at the side, away from the feeding device 2, of the dynamic spring sheet detection and adjustment device 15. The front conveying device 1 conveys the dynamic spring sheet in a predetermined posture. The feeding device 2 clamps and puts the dynamic spring sheet into the dynamic spring sheet detection and adjustment device 15 for corresponding inclination detection and adjustment. The discharging device 3 moves the dynamic spring sheet, after detection and adjustment, out of the dynamic spring sheet detection and adjustment device 15. Finally, the rear conveying device 4 receives the dynamic spring sheet clamped by the discharging device 3 and sends it to the next process. The dynamic spring sheet detection and adjustment device 15 is consistent with the dynamic spring sheet detection and adjustment system in the background art.

[0038] Refer to Figure 1 and Figure 2, the front conveying device 1, the feeding device 2, the movable spring piece detection and adjustment device 15, the discharging device 3 and the rear conveying device 4 are all installed with the same chassis 36. The front conveying device 1 comprises two front conveying belts 5 which are driven along the length direction of the chassis 36, the chassis 36 is provided with corresponding motors and belt rollers to drive the front conveying belts 5 to be synchronously driven (not shown in the figure), the front conveying belts 5 are circularly driven in the horizontal plane, and the two front conveying belts 5 are both conveyed to the feeding device 2. The front conveying belts 5 are uniformly and fixedly connected with a plurality of groups of two clamping blocks 51, the two clamping blocks 51 in the same group are fixedly connected to the two front conveying belts 5 one by one, the two clamping blocks 51 in the same group are both slidably connected with a clamping block 53 near the side surface, the clamping block 53 moves along the direction of the connecting line of the centers of the two clamping blocks 51 in the same group, and the clamping block 51 is provided with a clamping block spring 54, one end of the clamping block spring 54 abuts against the corresponding clamping block 53 so that the two clamping blocks 53 in the same group are close to each other when they are close to each other, the fixed section 11 of the movable spring piece is abutted and pressed by the two clamping blocks 53, and at this time, the deformation section 14 is located directly above the fixed section 11, only about half of the width of the fixed section 11 is abutted and pressed by the two clamping blocks 53, so that the feeding device 2 can clamp the half of the two clamping blocks 53 exposed outside the fixed section 11 in the subsequent process.

[0039] With reference to Figure 2 The clamping block 51 is fixedly connected with a pressure sensor 35, the pressure sensor 35 abuts against one end of the clamping block spring 54 away from the clamping block 53, so that the pressure sensor 35 bears the pressure from the fixed section 11 placed between the two clamping blocks 53 in the same group, and the pressure sensor 35 is electrically connected to the external controller, so that when the thickness of the movable spring piece exceeds the standard range, i.e. the thickness of the fixed section 11 is not within the standard range, the pressure borne by the pressure sensor 35 changes greatly, so that the pressure value obtained by the external controller according to the signal input by the pressure sensor 35 is not within the standard range preset in the external controller, at this time, the external controller can control the related audible and light alarm to alarm or the related clamping mechanism to act, so as to timely remove the movable spring piece with non-standard thickness. And the pressure sensor 35 can be integrated with a single-chip microcomputer and a wireless transmission module, so that the pressure sensor 35 can transmit signals to the external controller in a wireless transmission mode.

[0040] With reference to Figure 2, the upper part of the two clamping blocks 53 near one side of the two front conveyors 5 is shaped with a push inclined surface 55, the height of the two push inclined surfaces 55 near one side is lower, so as to insert the fixed section 11 between the two clamping blocks 53. The all clamping blocks 51 of one front conveyor 5 are fixedly connected with a limiting piece 52, so that when the arc section 13 is located directly above the limiting piece 52 and moves downward, the limiting piece 52 can abut against the arc section 13, so that the arc section 13 of the moving spring sheet can be smoothly inserted between the two clamping blocks 53 only when it is located directly above the clamping block 53 away from the limiting piece 52, so that the arc section 13 of the moving spring sheet clamped by the clamping block 53 is relatively consistent.

[0041] With reference to Figure 2 , the side surface of the clamping block 53 away from the limiting piece 52 is provided with a plurality of vertical channels 43 abutting against the fixed section 11, each channel 43 penetrates the push inclined surface 55, the width of the channel 43 is similar to the diameter of the rivet point 12, each channel 43 is vertically moved into the corresponding rivet point 12, the opposite sides of the upper end of each channel 43 are shaped with a point inclined surface 42, the height of the side with a farther distance between the two point inclined surfaces 42 of the same channel 43 is higher, so as to smoothly enter the rivet point 12 into the channel 43 along the point inclined surface 42. The bottom ends of all channels 43 of the same clamping block 53 are communicated with a same point channel 41, the length direction of the point channel 41 is consistent with the length direction of the chassis 36, the point channel 41 penetrates the vertical side surface of the clamping block 53 close to the feeding device 2, so as to move the fixed section 11 along the length direction of the point channel 41 out of the two clamping blocks 53.

[0042] With reference to Figure 3 , the chassis 36 is fixedly connected with a distance sensor 45 at one end of the front conveyor 5 close to the feeding device 2, the emitting end of the distance sensor 45 is located at the middle position of the line connecting the upper surfaces of the two clamping blocks 53 without the push inclined surface 55, and the two clamping blocks 53 are away from the distance sensor 45 with the transmission of the front conveyor 5. When the moving spring sheet is located between the two clamping blocks 53, the emitting end of the distance sensor 45 emits a light beam to the chassis 36, at this time, the external controller receives the signal input by the distance sensor 45, and the distance value obtained by calculation is much larger than the standard range preset in the external controller, at this time, the front conveyor 5 does not transmit. When the moving spring sheet is moved away by the feeding device 2, the two clamping blocks 53 are close to each other, at this time, the emitting end of the distance sensor 45 emits a light beam to the upper surfaces of the two clamping blocks 53, so that the distance value obtained by calculation by the external controller falls within the standard range preset in the external controller, at this time, the front conveyor 5 is controlled by the external controller to move a certain distance, that is, the next group of clamping blocks 53 moves to the position directly above the distance sensor 45.

[0043] With reference to Figure 1 and Figure 3The structure of the upper feeding device 2 and the lower feeding device 3 can be consistent, so the embodiment is described by taking the upper feeding device 2 as an example, and the lower feeding device 3 will not be described. The upper feeding device 2 comprises a horizontal rotation electric cylinder 56 detachably connected to the chassis 36, the rotation axis of the horizontal rotation electric cylinder 56 is vertical, the horizontal rotation electric cylinder 56 is fixedly connected with a shaft plate 39, the shaft plate 39 is detachably connected with a vertical rotation electric cylinder 57 away from one end of the horizontal rotation electric cylinder 56, the rotation axis of the vertical rotation electric cylinder 57 is horizontal, the rotation axis of the vertical rotation electric cylinder 57 is detachably connected with a linear electric cylinder 58, the power rod of the linear electric cylinder 58 is fixedly connected with an electric finger 59 for clamping the part of the two clamping blocks 53 exposed outside the fixed section 11, the clamping jaw of the electric finger 59 abutting the side of the fixed section 11 where the rivet point 12 is arranged is provided with a jaw groove 44, and the jaw groove 44 is used for the rivet point 12 to enter, so that the rivet point 12 is not easy to bear excessive pressure when the electric finger 59 clamps.

[0044] When the electric finger 59 clamps the part of the two clamping blocks 53 exposed outside the fixed section 11, the power rod of the linear electric cylinder 58 is retracted along the length direction of the chassis 36, so that the fixed section 11 is separated from the two clamping blocks 53, then the vertical rotation electric cylinder 57 drives the movable spring plate to rotate 90°, so that the movable spring plate changes from the state that the fixed section 11 is located directly above the deformation section 14 to the state that the fixed section 11 and the deformation section 14 are flush, at the same time, the horizontal rotation electric cylinder 56 drives the movable spring plate to rotate 180°, so that the movable spring plate rotates from the position close to the front conveying belt 5 to the position directly above the movable spring plate detection and adjustment device 15, then the power rod of the linear electric cylinder 58 is extended, so that the movable spring plate vertically moves down to the specified position of the movable spring plate detection and adjustment device 15, then the electric finger 59 no longer clamps the movable spring plate, the upper feeding device 2 is reset to clamp the next movable spring plate, and the lower feeding device 3 is also given a position to make way, so that after the movable spring plate is detected and adjusted, the lower feeding device 3 timely clamps the arc section 13 to transfer the movable spring plate. In addition, the horizontal rotation electric cylinder 56, the vertical rotation electric cylinder 57, the linear electric cylinder 58 and the electric finger 59 in the upper feeding device 2 can be provided with corresponding encoders, so that the external controller can acquire the real-time state of the upper feeding device 2 and the lower feeding device 3, so as to control the upper feeding device 2 and the lower feeding device 3 correspondingly.

[0045] Referring to Figure 4The rear conveying device 4 comprises a rear conveying belt 46 conveying along the length direction of the chassis 36, the rear conveying belt 46 conveying in the vertical plane, the chassis 36 being provided with corresponding motors and belt rollers to drive the rear conveying belt 46 to convey (not shown in the figure), the rear conveying belt 46 being uniformly and fixedly connected with a plurality of plug blocks 47, the upper surface of the plug block 47 being provided with a plug opening 37 for the vertical movement of the fixed section 11 to fall into, and part of the arc section 13 being able to enter into the plug opening 37, the width of the plug opening 37 being much greater than the thickness of the fixed section 11, so that when the discharging device 3 is clamped to the arc section 13 close to the upper opening of the plug opening 37 to be discharged, even if the whole moving spring plate is inclined in the vertical plane at this time, the end of the fixed section 11 away from the arc section 13 can also smoothly enter into the plug opening 37.

[0046] Referring to Figure 4 The plug block 47 is slidingly connected with an abutting block 48 along the width direction of the chassis 36, the abutting block 48 being able to enter into the plug opening 37 to abut against the side surface of the rivet point 12 of the fixed section 11, the plug block 47 being fixedly connected with an abutting block spring 49 forcing the abutting block 48 away from the plug opening 37, the chassis 36 being fixedly connected with a long strip 31 located at one side of the rear conveying belt 46, the length direction of the long strip 31 being consistent with the length direction of the chassis 36, one end of the long strip 31 close to the discharging device 3 being formed with a strip inclined surface 38, the side of the plug block 47 exposed to the outside of the abutting block 48 being formed with an abutting inclined surface 32, after the moving spring plate is put into the plug opening 37, the external controller controls the rear conveying belt 46 to move forward according to the state of the discharging device 3 at this time, so that the abutting inclined surface 32 can abut against the strip inclined surface 38, so that the abutting block 48 can be retracted into the plug opening 37 and abut against the fixed section 11, so that the moving spring plate tends to be vertical, so that the state of the moving spring plate tends to be consistent, and the abutting block 48 will not exert excessive pressure on the fixed section 11, so as to stably clamp and move out the moving spring plate from the plug opening 37 subsequently. The abutting block 48 is provided with a block groove 33 for the rivet point 12 to enter, the inside top surface of the block groove 33 being provided with a plurality of removal grooves 34 penetrating through the upper surface of the abutting block 48, the width of the removal groove 34 being greater than the diameter of the rivet point 12, and each removal groove 34 being provided for the vertical removal of one corresponding rivet point 12.

[0047] The implementation principle of the feeding and discharging system of the moving spring piece detection and adjustment device is as follows: the two front conveying belts 5 are driven to move the two clamping blocks 51 in the same group close to and synchronously forward, so that the moving spring piece between the two clamping blocks 53 is synchronously moved forward until the clamping blocks 51 move to positions right in front of the distance sensors 45, then the electric fingers 59 clamp and place the fixed section 11 into the moving spring piece detection and adjustment device 15, and the front conveying belt 5 is driven until the next moving spring piece is driven to the specified position, then the front conveying belt 5 stops driving, and the discharging device 3 clamps and places the moving spring piece whose detection and adjustment are completed into the corresponding spring piece discharging opening 37, and when the discharging device 3 releases the clamping of the moving spring piece, the rear conveying belt 46 is driven to make the abutting block 48 abut against the long strip 31, so that the abutting block 48 can abut against the fixed section 11, so that the moving spring piece can be kept in a vertical state.

[0048] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
