Description

Technical Field

[0001] This application relates to the field of electronic equipment processing and manufacturing, and in particular to a riveting press for relay electrode sheets with error correction function. Background Technology

[0002] Relays play a crucial role in electronic equipment, precisely controlling the on / off state of circuits and effectively preventing serious problems such as short circuits and open circuits caused by relay malfunctions. For example, in new energy vehicles, they control components like window regulator motors, windshield wiper motors, and central locking systems. In the event of a collision, a relay triggers the airbag ignition circuit to quickly deploy the airbag. During relay manufacturing, the precision and quality of each stage significantly impact the performance of the final product, especially the riveting process of internal components, whose quality directly affects the relay's performance and stability. The miniaturization and integration trends in electronic equipment also place higher demands on the dimensional accuracy and adaptability of relays.

[0003] To rivet the electrode sheet to the U-shaped metal base, existing technologies typically employ a riveting machine comprising a lower die positioning platform, an electrode sheet feeding mechanism, a metal base feeding mechanism, an upper die stamping mechanism, and a blanking mechanism. In practice, the lower die positioning platform is detachably equipped with a lower die featuring a positioning groove. The electrode sheet feeding mechanism first clamps the electrode sheet and places it in the rectangular positioning groove. Next, the metal base feeding mechanism places the metal base onto the electrode sheet in the positioning groove with the U-shaped groove opening facing the electrode sheet. Subsequently, the upper die stamping mechanism lowers the upper die to close with the lower die, riveting the bottom of the metal base to the top of the electrode sheet together, completing the riveting of the metal base and electrode sheet. Finally, the blanking mechanism transfers the riveted product.

[0004] However, existing riveting methods have significant drawbacks. Due to dimensional tolerances in the manufacturing process of the U-shaped metal base, the positioning between the metal base and the electrode plate is prone to misalignment. Furthermore, the metal base is easily deformed during riveting, resulting in large dimensional errors in the final riveted product. Moreover, the dimensional errors vary from product to product, making it impossible to guarantee uniform precision. This lack of precision leads to poor compatibility between the riveted product and other components during subsequent use, affecting the normal operation of relays in circuits, reducing relay performance and reliability, and consequently impacting the stability and lifespan of the entire electronic device. Summary of the Invention

[0005] In order to improve the riveting accuracy between the electrode sheet and the metal base, effectively avoid the metal base from shifting or deforming during the riveting process, which would lead to large dimensional errors in the final riveted product, and improve the dimensional consistency of the riveted product, this application provides a relay electrode sheet riveting machine with a correction error function.

[0006] This application provides a riveting machine for relay electrodes with error correction function, including a rotary worktable, an electrode feeding mechanism, a metal base feeding mechanism, an upper die stamping mechanism, a sliding clamping mechanism, and a product unloading mechanism. The rotary worktable can rotate intermittently and has four lower dies arranged around its top. The electrode feeding mechanism, metal base feeding mechanism, upper die stamping mechanism, and product unloading mechanism are each corresponding to one of the lower dies. The top of each lower die has a positioning groove for accommodating the electrode and abutment grooves located on opposite sides of the positioning groove. The positioning groove has openings on its opposite sides leading to the abutment groove, which are used to accommodate the metal base. The upper die stamping mechanism includes a liftable upper die with a stamping part at the bottom. The sliding clamping mechanism includes two sliding abutment blocks disposed on the upper die and a sliding drive for moving the sliding abutment blocks. The two sliding abutment blocks are located on both sides of the stamping part. The sliding abutment blocks are configured to extend from above into the abutment groove and abut against both sides of the metal base during the pressing down of the upper die.

[0007] By adopting the above technical solution, the rotary worktable can rotate intermittently. Its four lower dies, arranged in a ring around the table, sequentially correspond to the electrode feeding mechanism, the metal base feeding mechanism, the upper die stamping mechanism, and the product unloading mechanism, achieving continuous assembly line operation and improving the working efficiency of the riveting machine. The positioning groove at the top of the lower die is used to accommodate the electrode sheet, and the abutment grooves on opposite sides of the positioning groove, as well as the openings in the groove walls, are used to accommodate the metal base. This structure provides accurate positioning space for the electrode sheet and the metal base. During the riveting process, the upper die of the upper die stamping mechanism descends, and the sliding clamping mechanism on it plays a crucial role. The sliding drive component causes two sliding abutment blocks to move on both sides of the stamping section, extending from above into the abutment grooves and pressing against both sides of the metal base when the die is pressed down. Because the U-shaped metal base has dimensional tolerances during production, its positioning is prone to misalignment, and it is easily deformed during riveting. Conventional riveting leads to problems such as large dimensional tolerances and inconsistent precision. However, after the sliding abutment block is pressed against both sides of the metal base, it can fix and correct the sides of the metal base, limiting the displacement and deformation of the metal base during the riveting process. When riveting the metal base and electrode sheet in the stamping section, the position of the metal base is more stable, reducing dimensional deviations during the riveting process, thereby improving the precision of the riveted products and making the dimensions of each riveted product more uniform. As a result, the riveted products have better compatibility with other components in subsequent use, ensuring that the relay works normally in the circuit, improving the performance and reliability of the relay, and thus ensuring the stability and service life of the entire electronic device.

[0008] Preferably, the bottom of the upper mold is provided with two sliding grooves, and the sliding drive component drives the two sliding abutment blocks to move closer or further apart from each other in the two sliding grooves respectively.

[0009] By adopting the above technical solution, two sliding grooves are provided at the bottom of the upper mold. The sliding drive component can drive the two sliding abutment blocks to move closer or further apart within the two sliding grooves. During the riveting process, due to the dimensional tolerances of the metal base and its susceptibility to deformation under pressure, the riveted products may have large dimensional tolerances and inconsistent precision. However, the sliding abutment blocks can move within the sliding grooves under the action of the sliding drive component. When they move closer to each other, they can extend into the abutment grooves from above and press against both sides of the metal base.

[0010] Preferably, the shape of the inner wall of the positioning groove matches the outer contour of the electrode sheet.

[0011] By adopting the above technical solution, since the shape of the inner wall of the positioning groove matches the outer contour of the electrode sheet, the inner wall of the positioning groove can closely fit the outer contour of the electrode sheet when the electrode sheet is placed in the positioning groove, thereby playing a precise positioning role for the electrode sheet and avoiding the electrode sheet from shaking or shifting in the positioning groove. This improves the positional accuracy of the electrode sheet during the riveting process and helps to improve the accuracy and quality of the final riveted product.

[0012] Preferably, the shape of the opening matches the outer contour of the metal base.

[0013] By adopting the above technical solution, since the shape of the opening matches the outer contour of the metal base, the metal base can be accurately positioned when it is placed at the opening, thereby avoiding the positioning deviation between the metal base and the electrode sheet, and thus ensuring the uniform accuracy of the riveting products.

[0014] Preferably, the stamping part is a stamping column. When the two sliding abutment blocks approach each other and simultaneously press against both sides of the metal base, the stamping column continues to move downwards until it presses against the top of the metal base.

[0015] By adopting the above technical solution, during the riveting process, the sliding abutment blocks first extend into the abutment groove from above and abut against both sides of the metal base. Since the sliding abutment blocks are located on both sides of the stamping part, when the two sliding abutment blocks approach each other and simultaneously abut against both sides of the metal base, the position of the metal base can be initially fixed and adjusted, reducing its positional deviation. Then, the drive source at the top of the upper mold drives the stamping column to continue moving downwards until it abuts against the top of the metal base. Based on the positioning and guidance of both sides of the metal base by the sliding abutment blocks, the downward pressure of the stamping column can more accurately rivet the bottom of the metal base to the top of the electrode sheet, avoiding the metal base from shifting or deforming during the stamping process, thereby reducing the dimensional tolerance of the riveted products and improving the uniformity and accuracy of the riveted products.

[0016] Preferably, the upper mold is provided with four guide pillars, and the lower mold is provided with four guide holes corresponding to the four guide pillars, into which the guide pillars can extend.

[0017] By adopting the above technical solution, the four guide pillars of the upper mold cooperate with the four guide holes of the lower mold. During the riveting process, when the upper mold descends, the guide pillars will first extend into the guide holes. Due to the guiding effect of the guide pillars, the displacement of the upper mold in the horizontal direction can be restricted, allowing the upper mold to descend precisely along the direction of the guide holes, avoiding deviation of the upper mold during descent, thereby ensuring accurate mold closing between the upper and lower molds and improving the accuracy of riveting.

[0018] Preferably, the lower mold is provided with four limiting blocks that can abut against the top of the upper mold.

[0019] By adopting the above technical solution, the lower mold is equipped with four limiting blocks that can abut against the top of the upper mold. When the riveting machine performs riveting work, the upper mold descends, and the limiting blocks contact the top of the upper mold. This contact limits the further descent distance of the upper mold, preventing excessive downward pressure. Excessive pressure may cause the metal base and electrode sheet to be subjected to excessive pressure, resulting in deformation or damage, affecting the quality of the riveted product. The limiting blocks can precisely control the downward pressure of the upper mold, allowing the metal base and electrode sheet to be riveted under appropriate pressure, thus improving the accuracy and quality of the riveted product.

[0020] Preferably, the four lower molds are arranged at uniform intervals along the circumference of the rotary worktable.

[0021] By adopting the above technical solution, the four lower dies are evenly spaced along the circumference of the rotary worktable. This ensures that during the intermittent rotation of the rotary worktable, each lower die can sequentially and accurately correspond to the electrode sheet feeding mechanism, the metal base feeding mechanism, the upper die stamping mechanism, and the product unloading mechanism. The evenly spaced arrangement guarantees consistency and regularity in the path and stopping position of each lower die during rotation, avoiding operational errors in feeding, stamping, and unloading caused by positional deviations. This improves the stability and continuity of the relay electrode sheet riveting process, thereby enhancing overall production efficiency and product quality.

[0022] Preferably, an anti-oxidation spraying mechanism is provided between the metal base feeding mechanism and the upper die stamping mechanism. The anti-oxidation spraying mechanism includes a nozzle and a liquid supply assembly connected to the nozzle. The liquid supply assembly is used to provide anti-oxidation liquid to the nozzle for spraying onto the electrode sheet and metal base in the positioning groove.

[0023] By adopting the above technical solution, an anti-oxidation spraying mechanism is set between the metal base feeding mechanism and the upper die stamping mechanism. The liquid supply component delivers the anti-oxidation liquid to the nozzle, and the nozzle sprays the anti-oxidation liquid onto the electrode sheet and metal base in the positioning groove. During the riveting process, the electrode sheet and metal base come into contact with air and are prone to oxidation. The anti-oxidation liquid can form a protective film on the surface of the electrode sheet and metal base, effectively blocking air and preventing the electrode sheet and metal base from being oxidized, thereby improving the quality and stability of the riveted products.

[0024] Preferably, the product unloading mechanism includes a vertical sliding component, a horizontal sliding component, and a clamping hand. The vertical sliding component is disposed at the output end of the horizontal sliding component, and the clamping hand is disposed at the output end of the vertical sliding component for clamping the product in the positioning groove.

[0025] By adopting the above technical solution, the product unloading mechanism is equipped with a vertical sliding component, a horizontal sliding component, and a clamping hand. The vertical sliding component is located at the output end of the horizontal sliding component, and the clamping hand is also located at the output end of the vertical sliding component. The horizontal sliding component can drive the vertical sliding component and the clamping hand to move horizontally, allowing the clamping hand to move above the positioning slot. The vertical sliding component can drive the clamping hand to move vertically, allowing the clamping hand to descend into the positioning slot to clamp the product. After clamping the product, the vertical sliding component drives the clamping hand to rise, and the horizontal sliding component then drives it to move horizontally, transferring the product out of the positioning slot. This achieves effective unloading of the product from the positioning slot and improves production efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a sliding abutment block, during the die pressing process, the sliding abutment block extends from above into the abutment groove and presses against both sides of the metal base, which can limit the horizontal displacement of the metal base, thereby solving the problem of positioning misalignment between the metal base and the electrode sheet caused by dimensional tolerances in the production of the metal base, making the dimensions of each riveted product more uniform and ensuring the uniform accuracy of the riveted products. 2. The rotary worktable can rotate intermittently and has four lower molds on the top ring. The electrode sheet feeding mechanism, metal base feeding mechanism, upper mold stamping mechanism, and product unloading mechanism are set up one-to-one with the lower molds. In this way, each process can be carried out simultaneously when the rotary worktable rotates intermittently, without waiting for one product to complete all processes before processing the next product, thus improving riveting efficiency. 3. The inner wall shape of the positioning groove matches the outer contour of the electrode sheet, and the shape of the opening matches the outer contour of the metal base. When the electrode sheet is placed into the positioning groove and the metal base is placed into the opening, they can fit better, reducing positioning deviations caused by shape mismatch, thereby further improving positioning accuracy and reducing dimensional tolerances of riveted products.

[0029] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0030] Example 1 This application provides an embodiment of a relay electrode riveting press for adjusting error function, referring to... Figure 1 and Figure 2 The system includes a rotary worktable 1, an electrode feeding mechanism 2, a metal base feeding mechanism 3, an upper die stamping mechanism 4, a sliding clamping mechanism 5, and a product unloading mechanism 6. The rotary worktable 1 can rotate intermittently and has four lower dies 7 arranged around its top. The electrode feeding mechanism 2, the metal base feeding mechanism 3, the upper die stamping mechanism 4, and the product unloading mechanism 6 are arranged in a one-to-one correspondence with the lower dies 7. Through the intermittent rotation of the rotary worktable 1, each lower die 7 can pass through different mechanisms in sequence to complete the corresponding process, which improves the continuity and efficiency of the riveting work.

[0031] Specifically, the rotary worktable 1 in this embodiment can be composed of a motor and a turntable. The motor can be a stepper motor, which can precisely control the rotation angle and interval of the turntable, ensuring that each lower mold 7 accurately stops at the working position of its corresponding mechanism. The turntable is typically circular and can be made of metal, such as stainless steel, which has high strength and stability. The lower molds 7 are mounted on top of the turntable, and the four lower molds 7 are evenly spaced along the circumference of the rotary worktable 1. This layout makes the operation of each process more balanced and orderly.

[0032] Among them, reference Figure 3 and Figure 4Each of the four lower molds 7 has a positioning groove 71 on its top for accommodating the electrode sheet 8 and an abutment groove 72 located on opposite sides of the positioning groove 71. The groove walls on opposite sides of the positioning groove 71 have openings 73 leading to the abutment groove 72, which are used to accommodate the metal base 9. The inner wall shape of the positioning groove 71 matches the outer contour of the electrode sheet 8, ensuring that the electrode sheet 8 is accurately placed within the positioning groove 71 and preventing it from wobbling or shifting within it. The shape of the opening 73 matches the outer contour of the metal base 9, allowing the metal base 9 to precisely engage with the electrode sheet 8 through the opening 73. The positioning groove 71 and the abutment groove 72 provide an accurate positioning basis for the placement of the electrode sheet 8 and the metal base 9 and subsequent riveting.

[0033] Specifically, the electrode sheet loading mechanism 2, the metal base loading mechanism 3, and the product unloading mechanism 6 in this embodiment have similar structures, each consisting of a vertical sliding component, a horizontal sliding component, and a gripper. The vertical sliding component is located at the output end of the horizontal sliding component, and the gripper is located at the output end of the vertical sliding component for gripping. The vertical and horizontal sliding components can employ a screw-slider mechanism or a cylinder-driven mechanism, enabling the gripper to move in both vertical and horizontal directions. The gripper can be a pneumatic gripper, capable of firmly gripping the product and transferring it to a designated position. That is, the electrode sheet loading mechanism 2 places the electrode sheet in the positioning groove 71 of the corresponding workstation, the metal base loading mechanism 3 places the metal base on top of the electrode sheet in the positioning groove 71 of the corresponding workstation, and the product unloading mechanism 6 transfers the riveted product from the positioning groove 71 of the corresponding unloading workstation to the product area.

[0034] Specifically, refer to Figure 5 and Figure 6 In this embodiment, the upper die stamping mechanism 4 includes a liftable upper die 41, with a stamping section at the bottom of the upper die 41. The lifting and lowering of the upper die 41 can be achieved by a stamping cylinder 43. The output end of the stamping cylinder 43 is fixedly connected to the upper die 41 via four connecting columns 44. Cylinders have the advantages of fast response and simple structure; hydraulic devices can provide greater pressure and are suitable for situations requiring larger stamping force. The stamping section consists of a stamping column 42 and a driving cylinder 45 that drives the stamping column 42. The stamping column 42 is typically cylindrical and can be made of high-strength alloy steel to ensure it does not deform during stamping. In this embodiment, the driving cylinder 45 is located at the top of the upper die 41, and the four connecting columns 44 are arranged in a rectangular pattern around the driving cylinder 45.

[0035] The sliding clamping mechanism 5 includes two sliding abutment blocks 51 disposed on the upper mold 41 and a sliding drive component 52 for driving the sliding abutment blocks 51 to move. The two sliding abutment blocks 51 are located on both sides of the stamping column 42. The bottom of the upper mold 41 is provided with two sliding grooves. The sliding drive component 52 drives the two sliding abutment blocks 51 to move closer or further apart from each other in the two sliding grooves. The sliding drive component 52 is a small finger cylinder. The two sliding abutment blocks 51 are respectively fixedly disposed on the two output finger parts of the finger cylinder, which can precisely control the movement of the sliding abutment blocks 51. During the process of the stamping cylinder 43 driving the upper mold 41 to press down, the two sliding abutment blocks 51 extend into the abutment groove 72 from above. Driven by the finger cylinder, the two sliding abutment blocks 51 approach each other and simultaneously press against both sides of the metal base. Then, the driving cylinder 45 drives the stamping column 42 to continue moving downward until it presses against the top of the metal base. In this way, during the riveting process, the sliding abutment blocks 51 can position and fix the metal base, reduce the error caused by the dimensional tolerance and deformation of the metal base, and improve the accuracy of the riveted product.

[0036] The upper mold 41 has four guide pillars 46 at its bottom, and the lower mold 7 has four guide holes 74 corresponding to the four guide pillars 46, allowing the guide pillars 46 to extend into them. The cooperation between the guide pillars 46 and the guide holes 74 ensures the accuracy and stability of the upper mold 41 and the lower mold 7 during the mold closing process, preventing the upper mold 41 from shifting downwards. Furthermore, the lower mold 7 is also provided with four limiting blocks 75 that can abut against the top of the upper mold 41. The limiting blocks 75 can limit the downward pressing depth of the upper mold 41, preventing excessive stamping from damaging the product.

[0037] The implementation principle of this embodiment is as follows: The rotary worktable 1 rotates intermittently, sequentially sending the lower mold 7 to the electrode sheet feeding mechanism 2, the metal base feeding mechanism 3, the anti-oxidation spraying mechanism, the upper mold stamping mechanism 4, and the product unloading mechanism 6. The electrode sheet feeding mechanism 2 places the electrode sheet into the positioning groove 71, and the metal base feeding mechanism 3 places the metal base on the electrode sheet through the opening 73. The upper mold 41 of the upper mold stamping mechanism 4 descends, and the sliding abutment block 51 of the sliding clamping mechanism 5 extends into the abutment groove 72 to press against both sides of the metal base. The stamping column 42 stamps and rivets the metal base, reducing errors in the riveting process. Finally, the product unloading mechanism 6 transfers the riveted product. The entire process improves the accuracy and consistency of the relay electrode sheet riveting product, reduces problems caused by dimensional tolerances and deformation, and at the same time, the product is treated with anti-oxidation, improving the quality and reliability of the product, which is a significant improvement compared to the prior art.

[0038] Example 2 The difference between this embodiment and the above embodiments is that: (Refer to...) Figure 7An anti-oxidation spraying mechanism 10 is added between the metal base feeding mechanism 3 and the upper die stamping mechanism 4. The anti-oxidation spraying mechanism includes a nozzle and a liquid supply assembly connected to the nozzle. The liquid supply assembly provides anti-oxidation liquid to the nozzle for spraying onto the electrode sheet and metal base in the positioning groove 71. The nozzle is an atomizing nozzle, which can evenly spray the anti-oxidation liquid onto the surface of the electrode sheet and metal base to prevent oxidation before and after riveting. The liquid supply assembly includes a storage tank and a pump, which delivers the anti-oxidation liquid from the storage tank to the nozzle. Since the electrode sheet and metal base are easily exposed to air during transportation and prone to oxidation, the anti-oxidation liquid can form a protective film on the surface of the electrode sheet and metal base, effectively blocking air and preventing oxidation, thereby improving the quality and stability of the riveted products.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
