Description

Technical Field

[0001] The present invention relates to the technical field of riveting equipment, and particularly relates to a workpiece riveting and soldering device. Background Art

[0002] In the process of machining, there is often a machining process of riveting a solder sheet to a reed. For example: the assembly of an automotive electric door lock requires riveting a door lock fixing plate to a pull cord post, and the joint of the riveting requires relatively high strength and needs to withstand a certain tensile force; another example is: the assembly of electrical component pins, which needs to meet the requirements of rotational positioning while satisfying the requirements of electrical signal transmission.

[0003] Using traditional manual riveting or general radial riveting machines can only achieve single-point riveting based on position control. For the riveting of ultra-thin reeds, it is extremely easy to cause local deformation of the reeds, or excessive pressure to cause cracks in the printed brush board. At the same time, the positioning accuracy requirements for reeds in the same group are extremely high. Only relying on single-point riveting, it is extremely easy to cause inconsistent distances between reeds, and it is impossible to achieve reliable contact between the front-end contacts of the reeds and the bus bar, affecting the stable transmission of electrical performance; in addition, when the existing riveting device rivets a solder piece to a workpiece, the workpiece is prone to circumferential deformation under single-sided force, thereby affecting the product effect after riveting.

[0004] In order to solve the deficiencies of the existing technology, people have carried out long-term explorations and proposed various solutions. For example, a Chinese patent document discloses an automatic riveting device for ultra-thin reeds of a satellite disc-type conductive slip ring [CN201910662412.4], which includes a riveting machine, a riveting head, a riveting and fixing clamping tooling, a precision driving platform, a sensor, a control system, etc. The precise positioning of the rivet, the reed, and the printed brush board is achieved through the riveting and fixing clamping tooling; the control system controls the riveting machine, the riveting head is magnetically attracted and pressed downward at high speed until a certain position; the sensor real-time feeds back the riveting force to the control system, and finally realizes riveting with a fixed force value; after one-point riveting, the control system controls the precision driving platform to accurately move to the next riveting point and repeats the above actions to achieve automatic riveting of the reeds.

[0005] The above solution solves to a certain extent the problem that the single-point riveting method of the existing riveting device easily affects the riveting quality of the reeds, but this solution still has many deficiencies. For example: when the existing riveting device rivets a solder piece to a workpiece, the workpiece is prone to circumferential deformation under single-sided force, thereby affecting the riveting effect and further affecting the product effect after riveting. Summary of the Invention

Detailed implementation mode

[0026] The following further elaborates on the present invention in conjunction with the accompanying drawings and specific implementation modes.

[0027] As Figure 1-7 shown, a workpiece riveting and soldering device includes a workpiece positioning pedestal 1 with a workpiece positioning chute 11 at its end. One side of the workpiece positioning pedestal 1 is connected through an elastic sliding connection assembly 2 to a pressing mechanism 3 capable of pushing the workpiece positioning pedestal 1 to move. A pressing column 4 is vertically arranged inside the pressing mechanism 3, with one end inserted into the circumferential inner side of the workpiece positioning pedestal 1. And on the workpiece positioning pedestal 1 and between the pressing column 4 and the workpiece positioning chute 11, there is a solder tab insertion station 12 for inserting the solder tab 9. On the side of the workpiece positioning pedestal 1 away from the pressing mechanism 3, there is a passive pressing and positioning mechanism 5 capable of being inserted and connected to the workpiece positioning pedestal 1, and a passive riveting structure 6 is arranged on the circumferential inner side of the passive pressing and positioning mechanism 5.

[0028] During processing, first, the workpiece is slid and inserted along the workpiece positioning chute 11, and the solder tab is inserted into the solder tab insertion station 12. At this time, the pressing mechanism 3 is used to push the workpiece positioning pedestal 1 to move until it is inserted and connected to the passive pressing and positioning mechanism 5 and continuously applies a pushing force to the passive pressing and positioning mechanism 5, so that the passive riveting structure 6 extends to extrude a fixed-point riveting column for the workpiece. And when continuing to apply the force, the pressing mechanism 3 pushes one end of the pressing column 4 to cut off the solder tab and push it to the riveting column at the bottom of the workpiece, thereby achieving the purpose of riveting.

[0029] Embodiment 1

[0030] The workpiece positioning pedestal 1 includes a connecting base 13. An extended pedestal 14 is integrally formed on one side of the connecting base 13. The workpiece positioning chute 11 at the upper end is arranged at the end of the extended pedestal 14. And a guiding sliding channel 15 through which the crimping cylinder 4 can be inserted is provided through the inner circumference of the workpiece positioning pedestal 1. Both ends of the workpiece positioning chute 11 are open. And a limiting convex block 16 for limiting the workpiece is arranged on the open side of the workpiece positioning chute 11 and located at the guiding sliding channel 15. And an inserted guiding and limiting structure 7 is arranged between both sides of the limiting convex block 16 and one end of the passive pressing and positioning mechanism 5. The workpiece positioning chute 11 is used for the sliding insertion of one end of the workpiece, and the limiting convex block 16 is used for positioning the position of one end of the workpiece.

[0031] Among them, the elastic sliding connection assembly 2 includes positioning connection holes 21 arranged on the connecting base 13 and on both sides of the extended pedestal 14. The connecting base 13 is connected to one side of the pressing mechanism 3 through a sliding connection cylinder 22 arranged in the positioning connection hole 21. And the sliding connection cylinder 22 is composed of a limiting ring body 221 and a guiding cylinder 222. An annular limiting step 211 for abutting against the limiting ring body 221 is arranged on the inner circumference of the positioning connection hole 21. When the connecting base 13 moves, it can drive the top pressure connection block 31 to move synchronously. When the connecting base 13 is subjected to resistance and remains stationary, and when the top pressure plate 37 continues to apply a thrust, the top pressure connection block 31 overcomes the limiting force of the limiting spring 33 and moves towards the connecting base 13 along the guiding cylinder 222. Thus, one end of the crimping cylinder 4 slides out of the guiding sliding channel 15 to cut off the solder tab 9 and push it to the bottom of the workpiece 8. And there is an insertion relief channel at the axis of the crimping cylinder 4 here.

[0032] Furthermore, the pressing mechanism 3 includes a top pressure connection block 31. A plurality of spring insertion holes 32 are provided on the top pressure connection block 31. And a limiting spring 33 is inserted into the spring insertion holes 32. A plurality of spring positioning grooves 34 for positioning one end of the limiting spring 33 are provided at the bottom of the connecting base 13. And a through hole 35 through which the crimping cylinder 4 can pass is provided at the axis of the top pressure connection block 31. There is a top pressure gap 36 between the connecting base 13 and the top pressure connection block 31. And a top pressure plate 37 is arranged on the side of the top pressure connection block 31 away from the connecting base 13. A plurality of top pressure positioning grooves 38 for limiting the other end of the limiting spring 33 are provided on the top pressure plate 37. And the bottom of the crimping cylinder 4 abuts against the top pressure plate 37. When the top pressure plate 37 applies a thrust, the top pressure connection block 31 drives the workpiece positioning pedestal 1 to move synchronously.

[0033] The principle of this embodiment is as follows: By applying a thrust force through the top pressure plate 37, the workpiece positioning pedestal 1 is driven to move synchronously towards the passive pressing and positioning mechanism 5 by means of the limiting spring 33 and the sliding connection cylinder 22. When the workpiece positioning pedestal 1 encounters the limiting resistance of the workpiece positioning pedestal 1, the top pressure plate 37 continuously applies a thrust force, and the top pressure connection block 31 overcomes the limiting force of the limiting spring 33 and moves along the guide cylinder 222 towards the connection base 13, so that one end of the crimping cylinder 4 slides out of the guide sliding channel 15, and the truncated solder tab is pushed to the bottom of the workpiece and pressed firmly against the bottom of the workpiece.

[0034] Embodiment Two

[0035] The passive pressing and positioning mechanism 5 includes a passive linkage seat 51. One side of the passive linkage seat 51 is provided with a workpiece pressing part 52, and the other side is connected with a top pressure limiting structure 54 through an elastic pressing linkage component 53. The plug-in type guiding and limiting structure 7 is arranged between the workpiece pressing part 52 and the workpiece positioning chute 11. The top pressure limiting structure 54 is used to prevent the passive linkage seat from moving over-position and has the function of resisting the thrust force of the top pressure plate 37.

[0036] Among them, the plug-in type guiding and limiting structure 7 includes a number of limiting slots 71 arranged on the workpiece pressing part 52, and a number of limiting rods 72 corresponding to the limiting slots 71 are arranged at the end of the workpiece positioning chute 11. The mutual plugging of the limiting rods 72 and the limiting slots 71 is conducive to the conduction of force and improves the linkage effect.

[0037] Visibly, the elastic pressing linkage component 53 includes a number of return springs 531 arranged on the passive linkage seat 51. One end of the return spring 531 is arranged in the spring return groove 532 on one side of the passive linkage seat 51, and the other end of the return spring 531 is arranged in the spring limiting groove 542 on one side of the limiting plate 541 of the top pressure limiting structure 54. A number of sliding connection cylinders 533 are arranged between the passive linkage seat 51 and the limiting plate 541, and a number of guiding sliding cylinders 534 are also arranged between the passive linkage seat 51 and the limiting plate 541. One end of the guiding sliding cylinder 534 is positioned in the cylinder positioning groove 543 on one side of the limiting plate 541. When the passive linkage seat 51 is subjected to a thrust force and moves backward overcoming the return force of the return spring 531, one end of the passive riveting structure 6 extends out of the connecting rod channel 69, and one end of the sliding connection cylinder 533 has a limiting snap ring for limiting the return position of the passive linkage seat 51. The sliding connection cylinder 533, the limiting plate 541, and the top pressure block 544 remain stationary, and the guiding sliding cylinder 534 is used for sliding guiding and positioning the movement of the passive linkage seat 51, so as to ensure the accuracy of the riveting position of the riveting connecting rod 6.

[0038] Specifically, the top pressure limiting structure 54 includes a top pressure block 544 disposed on the side of the limiting plate 541 away from the passive linkage seat 51. A top pressure limiting cylinder 545 for connecting an external device is connected to the top pressure block 544. A positioning connection jack 546 coaxial with the sliding connection cylinder body 533 is provided on the top pressure block 544 and the limiting plate 541. A passive gap 547 exists between the limiting plate 541 and the passive linkage seat 51. The positioning connection jack 546 is used to connect the sliding connection cylinder body 533.

[0039] Preferably, the passive riveting structure 6 includes a riveting connecting rod 61. One end of the riveting connecting rod 61 has an annular positioning seat 62 and the other end is provided with a riveting portion 63. A sliding connecting rod 64 is provided between the annular positioning seat 62 and the riveting connecting rod 61. A limiting groove 65 for limiting the annular positioning seat 62 is provided at the center of the limiting plate 541. A plugging channel 66 through which the riveting connecting rod 61 can penetrate is provided at the center of the limiting plate 541. An inclined portion corresponding to the annular limiting portion 68 is provided at the connection between the sliding connecting rod 64 and the riveting connecting rod 61.

[0040] Among them, the annular positioning seat 62 is limited by the top pressure block 544. A sliding connection channel 67 coaxial with the plugging channel 66 is provided at the centers of the passive linkage seat 51 and the workpiece pressing portion 52. An annular limiting portion 68 for limiting the sliding connecting rod 64 is provided at one end of the sliding connection channel 67. A connecting rod channel 69 coaxial with and communicating with the sliding connection channel 67 is provided at the center of the workpiece pressing portion 52 near one end of the limiting plug 72, and the diameter of the connecting rod channel 69 is smaller than the diameter of the sliding connection channel 67. The annular limiting portion 68 is used to limit the extending length of the riveting connecting rod 61.

[0041] The principle of this embodiment is as follows: When the passive linkage seat 51 is subjected to a thrust force, it moves toward the limiting plate 541 against the restoring force of the restoring spring 521, so that one end of the riveting connecting rod 61 is passively extended out of the connecting rod channel 69 to perform a fixed-point extrusion on one side of the workpiece 9, causing a riveting column to protrude on the other side of the workpiece. When the passive linkage seat 51 loses the thrust force, it is reset due to the restoring force of the restoring spring 521, and the reset position is limited by the sliding connection cylinder body 533.

[0042] In summary, when the workpiece 9 is processed by the present invention, first, the workpiece 9 is slid and inserted along the workpiece positioning chute 11. The position of the workpiece 9 is positioned by the limiting convex block 16, and the solder tab is inserted into the solder tab insertion station 12. At this time, a thrust is applied by the top pressing plate 37 to drive the workpiece positioning pedestal 1 to move synchronously towards the passive pressing and positioning mechanism 5 by the top pressing connection block 31 until the limiting insertion rod 72 is inserted into the limiting insertion slot 71. When a continuous thrust is applied, when the passive linkage seat 51 is subjected to the thrust, it moves towards the limiting plate 541 against the restoring force of the restoring spring 521, so that one end of the riveting connecting rod 61 is passively extended out of the connecting rod channel 69 to perform fixed-point extrusion of the riveting column on the workpiece 9; when one side of the passive linkage seat 51 is limited by the limiting plate 541, it stops moving. At this time, the top pressing plate 37 continues to apply a thrust to make the top pressing connection block 31 move along the guiding cylinder 222 towards the connecting base 13 against the limiting force of the limiting spring 33. Since the connecting base 13 is limited by the passive linkage seat 51, it remains stationary. The top pressing plate 37 and the top pressing connection block 31 keep moving. When the top pressing connection block 31 is limited by the connecting base 13, the top pressing connection block 31 stops moving. At this time, one end of the pressing column body 4 slides out of the guiding sliding channel 15, and the solder tab 9 is cut off and pushed to the fixed-point extrusion part at the bottom of the workpiece, achieving the purpose of riveting the solder tab 9 to the workpiece 8.

[0043] Wherein, when the riveting connecting rod 61 performs fixed-point extrusion on one side of the workpiece 8, the other side of the workpiece 8 is positioned through the workpiece positioning chute 11. When the pressing column body 4 cuts off the solder tab and pushes it to the riveting column, the other side of the workpiece 8 is pressed and positioned through the workpiece pressing part 52. Therefore, it can effectively ensure that both sides of the workpiece 8 are evenly stressed during processing, avoiding the situation of circumferential deformation.
