Description

Technical Field

[0001] This invention relates to the field of alloy resistance processing technology, specifically a stamping die for adjusting the accuracy of alloy resistance. Background Technology

[0002] In the field of electronic component manufacturing, alloy resistors are widely used in various electronic devices such as power supplies, home appliances, automotive electronics, and industrial control systems due to their advantages such as stable resistance, high power density, and small temperature coefficient. The resistance accuracy of alloy resistors is a core indicator that determines their performance, directly affecting the operational stability and control precision of electronic equipment. Stamping and resistance accuracy adjustment are two key processes in the production of alloy resistors, and the efficiency and synergy between these two processes directly determine production capacity, product qualification rate, and production cost.

[0003] Based on the above, the inventors have discovered the following problems: Currently, in the production process of alloy resistors in the industry, the resistance adjustment and stamping processes are independent and completely disconnected. Stamping and resistance accuracy adjustment need to be completed in two separate processes, and materials need to be transferred between the two processes. The alloy resistor blanks are small in size, and collisions, friction, and falling are likely to occur during transfer, packaging, and unloading, resulting in blank deformation and damage, causing material loss. Furthermore, the transfer time is long between different production areas, resulting in low production efficiency and making it difficult to meet the needs of large-scale and efficient production of alloy resistors.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a stamping die for adjusting the precision of alloy resistance, in order to achieve a more practical purpose. Summary of the Invention

[0005] The purpose of this invention is to provide a stamping die for adjusting the accuracy of alloy resistors, so as to solve the problem mentioned in the background art that the adjustment of alloy resistors and the stamping process are independent and completely disconnected from each other in the production process of alloy resistors in the industry.

[0006] In view of the above problems, the technical solution proposed by the present invention is as follows: A stamping die for adjusting the resistance accuracy of an alloy includes a base. A stamping mechanism and a resistance adjustment mechanism are respectively provided on both sides of the upper end of the base. The stamping mechanism includes a lower die holder, with a stamping assembly at its upper end. The bottom end of the lower die holder is connected to one side of the upper end of the base. Cavities are provided on both sides of the lower die holder's interior. A material groove is formed at the center of the upper end of the lower die holder. A moving groove is formed at the bottom end of the material groove inside the lower die holder. Conveying assemblies are provided inside each cavity. The resistance adjustment mechanism includes a moving frame and a touch display. The bottom ends of the moving frame and the touch display are respectively connected to both sides of the upper end of the base. A resistance adjustment assembly is provided at the upper end of the moving frame, and a moving assembly is provided on one side of the moving frame.

[0007] Furthermore, one end of the movable groove extends through the lower mold base to the outside, and both sides of the movable groove are respectively connected to a pair of cavities.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the moving groove passes through the lower mold base and communicates with the cavity, which not only provides sliding space for the push block to facilitate the pushing of the molded alloy resistor from the bottom of the material groove, but also realizes the linkage between the moving component and the moving groove, ensuring that the molded alloy resistor is quickly transferred to the resistance adjustment station.

[0009] Furthermore, the conveying assembly includes a pair of mounting frames, which are disposed inside the cavity near the moving groove. Rollers are rotatably connected inside each mounting frame. A conveyor belt is fitted between the pair of rollers. Push blocks are mirror-mounted on both sides of the conveyor belt. The push blocks are slidably connected to the moving groove. A first servo motor is fixedly mounted on the top of one of the mounting frames, and the output end of the first servo motor is drivenly connected to one of the rollers.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the first servo motor drives the roller to rotate, which drives the conveyor belt to run smoothly. The pusher moves with the conveyor belt and accurately pushes the alloy resistor formed at the bottom of the material trough to move along the moving groove. This can realize the continuous and automated conveying of the alloy resistor after stamping, which is suitable for mass production needs.

[0011] Furthermore, a tensioning mechanism is provided on one side of the bottom of the cavity. The tensioning mechanism includes a fixed frame, the bottom of which is connected to the bottom of the cavity. A connecting frame is slidably inserted into one side of the fixed frame. A tensioning wheel is rotatably connected to one end of the connecting frame. The tensioning wheel is rolledly connected to the inner side of the conveyor belt. An adjusting screw is threadedly connected to the center of the fixed frame. One end of the adjusting screw is rotatably connected to one side of the connecting frame.

[0012] The beneficial effect of adopting the above-mentioned further solution is that rotating the adjusting screw can push the connecting frame to slide along the fixed frame, thereby adjusting the position of the tensioning wheel, realizing the tension adjustment of the conveyor belt, avoiding the conveyor belt from loosening and slipping, ensuring the stable operation of the conveying component, and improving the accuracy of conveying the formed alloy resistor.

[0013] Furthermore, the stamping assembly includes a top plate, two pairs of columns, and an upper die base. The two pairs of columns are respectively disposed on both sides of the lower die base. The bottom end of the columns is connected to the upper end of the base. The bottom end of the top plate is connected to the top end of the two pairs of columns. The two ends of the upper die base are slidably connected to the two pairs of columns respectively. A first electric telescopic rod is inserted into the center of the top plate. The output end of the first electric telescopic rod is connected to the top end of the upper die base.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the column provides guiding support for the top plate and the upper die base, the first electric telescopic rod drives the upper die base to rise and fall smoothly along the column, realizes the precise docking of the stamping head and the stamping base, the stamping force and stroke are controllable, and ensures the consistency of alloy resistance stamping.

[0015] Furthermore, a stamping seat is bolted to the upper end of the lower die base, and the central punch hole of the stamping seat is connected to the material groove. A stamping head is bolted to the bottom end of the upper die base, and the stamping head and the punch hole of the stamping seat are located on the same axis.

[0016] The beneficial effects of adopting the above-mentioned further solution are that the punch head and the punch seat are coaxially set to ensure punching accuracy, avoid blank punching deviation, improve product forming quality, and through the cooperation of the punch head and the punch seat, the stamped alloy resistor is continuously squeezed into the interior of the material groove, thereby facilitating the subsequent resistance adjustment work.

[0017] Furthermore, the trimming assembly includes a movable frame and a laser trimming machine. The movable frame has sliding grooves on both sides, and the bottom ends of the movable frame are slidably connected to a pair of sliding grooves on both sides. A second electric telescopic rod is fixedly installed on the upper end of the movable frame, and one end of the laser trimming machine is sleeved with the output end of the second electric telescopic rod.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the movable frame slides along the slide groove, and in conjunction with the second electric telescopic rod, the horizontal and vertical positions of the laser trimming machine can be flexibly adjusted to achieve precise positioning and trimming of the stamped alloy resistor, adapting to the precision adjustment requirements of resistors of different specifications, and making trimming precise and efficient.

[0019] Furthermore, a lead screw is rotatably connected inside the movable frame, and a slider is threaded onto the lead screw. The two ends of the slider are fixedly connected to the bottom sides of the movable frame, respectively. A second servo motor is fixedly installed at one end of the movable frame, and the output end of the second servo motor is connected to the lead screw drive.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the second servo motor drives the lead screw to rotate, which drives the slider and the movable frame to move synchronously. The transmission is precise and the movement is smooth. It can accurately control the horizontal displacement of the laser trimming machine, ensure the precise trimming position, and improve the consistency of alloy resistance precision adjustment.

[0021] Furthermore, the moving component includes a first conveyor belt and a pair of limiting frames, one end of the first conveyor belt being connected to the bottom of the outlet end of the moving trough, and the pair of limiting frames being disposed on both sides of the outlet end of the moving trough.

[0022] The beneficial effects of adopting the above-mentioned further scheme are that the first conveyor belt receives the stamped resistors sent out by the moving trough and realizes the smooth transfer to the resistance adjustment station; a pair of limit frames limit the resistors during the transfer process to prevent deviation, ensure smooth transfer, and connect the stamping and resistance adjustment processes.

[0023] Furthermore, a second conveyor belt is installed at the other end of the first conveyor belt, and a gantry frame is installed at one end of both the first and second conveyor belts. An infrared counter is inserted into the center of the upper end of each gantry frame, and the probes of a pair of infrared counters are respectively facing the first and second conveyor belts.

[0024] The beneficial effects of adopting the above-mentioned further solution are that the first conveyor belt and the second conveyor belt work together to realize the transfer of resistors from the stamping station to the resistance adjustment station. The stamped resistors enter the second conveyor belt and are adjusted by the laser resistance adjustment machine. After the resistance adjustment is completed, they are conveyed away, and the first conveyor belt continues to transport them, thereby improving production efficiency. The infrared counter counts the number of resistors in real time during the transfer process, which is convenient for production counting and capacity statistics. It also identifies the number of alloy resistance adjustments that have passed and controls the movement speed of the first and second conveyor belts in conjunction with the touch screen display.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: The stamping die for adjusting the precision of alloy resistors has a base that provides stable support for the entire device. The lower die base of the stamping mechanism, together with the stamping assembly and the conveying assembly, realizes the stamping and precise conveying of the alloy resistor blank. The material groove allows the stamped alloy resistors to be temporarily stored in an arranged manner. The height of the moving groove is adapted to the height of the alloy resistors, making it convenient to remove the alloy resistors located at the bottom of the material groove one by one. The moving frame of the resistance adjustment mechanism works with the resistance adjustment assembly to realize the precise resistance adjustment of the alloy resistors after stamping. The moving assembly completes the transfer of the unadjusted resistors and the finished products. The touch screen facilitates parameter setting and monitoring. The whole system realizes the integrated operation of alloy resistor stamping and precision resistance adjustment, with a high degree of automation, improving production efficiency and product precision.

[0031] In one embodiment of the present invention, the conveying assembly further includes a pair of mounting brackets 208, which are disposed inside the cavity 214 near the moving groove 207.

The bottom end of the top plate 201 is connected to the top end of the two pairs of columns 202. The two ends of the upper die base 204 are slidably connected to the two pairs of columns 202. A first electric telescopic rod 206 is inserted into the center of the top plate 201. The output end of the first electric telescopic rod 206 is connected to the top end of the upper die base 204. The columns 202 provide guiding support for the top plate 201 and the upper die base 204. The first electric telescopic rod 206 drives the upper die base 204 to rise and fall smoothly along the columns 202, realizing the precise docking of the stamping head 213 and the stamping seat 205. The stamping pressure and stroke are controllable, ensuring the consistency of alloy resistance stamping.

Through the cooperation of the stamping head 213 and the stamping seat 205, the stamped alloy resistor is continuously squeezed into the interior of the material groove 215, thereby facilitating the subsequent resistance adjustment work.

[0035] In one embodiment of the present invention, the resistance adjustment assembly further includes a movable frame 308 and a laser resistance adjustment machine 310. The movable frame 308 has sliding grooves 315 on both sides. The bottom ends of the movable frame 308 are slidably connected to a pair of sliding grooves 315. A second electric telescopic rod 309 is fixedly installed on the upper end of the movable frame 308. One end of the laser resistance adjustment machine 310 is sleeved with the output end of the second electric telescopic rod 309. The movable frame 308 slides along the sliding grooves 315.

[0036] In one embodiment of the present invention, a lead screw 312 is rotatably connected inside the movable frame 301, and a slider 313 is threadedly connected to the lead screw 312.

The output end of the second servo motor 311 is connected to the lead screw 312 for transmission.

It can accurately control the horizontal displacement of the laser trimming machine 310, ensure the precise trimming position, and improve the consistency of alloy resistance precision adjustment.

[0037] In one embodiment of the present invention, the moving component further includes a first conveyor belt 303 and a pair of limiting frames 305. One end of the first conveyor belt 303 is connected to the bottom of the outlet end of the moving trough 207. The pair of limiting frames 305 are disposed on both sides of the outlet end of the moving trough 207. The first conveyor belt 303 receives the stamped resistors sent out by the moving trough 207, realizing a smooth transfer to the resistance adjustment station. The pair of limiting frames 305 limit the resistors during the transfer process to prevent deviation, ensure smooth transfer, and connect the stamping and resistance adjustment processes.

[0038] In one embodiment of the present invention, a second conveyor belt 304 is further installed at the other end of the first conveyor belt 303. A gantry frame 306 is installed at one end of both the first conveyor belt 303 and the second conveyor belt 304. An infrared counter 307 is inserted into the center of the upper end of each gantry frame 306. The probes of the pair of infrared counters 307 face the first conveyor belt 303 and the second conveyor belt 304 respectively. The first conveyor belt 303 and the second conveyor belt 304 cooperate to realize the transfer of resistors from the stamping station to the resistance adjustment station. The stamped resistors enter the second conveyor belt 304 and are adjusted by the laser resistance adjustment machine 310. After the resistance adjustment is completed, they are conveyed away, and the first conveyor belt 303 continues to convey, thereby improving production efficiency. The infrared counters 307 count the number of resistors in real time during the transfer process, which is convenient for production counting and capacity statistics. They also identify the number of alloy resistance adjustments that have passed through and control the movement speed of the first conveyor belt 303 and the second conveyor belt 304 with the help of the touch display 302.

[0039] Specifically, the working principle of this stamping die for adjusting the precision of alloy resistors is as follows: During use, the alloy resistor blank is first placed at the end of the upper die holder 204 for transport. The stamping and resistance adjustment parameters are preset via the touch display 302. The first electric telescopic rod 206 is activated to drive the upper die holder 204 downwards along the column 202, ensuring precise alignment and mold closing between the stamping head 213 and the stamping seat 205, completing the blank stamping. The formed resistors automatically fall into the material groove 215 for temporary storage. Subsequently, the first servo motor 212 drives the roller 209 to rotate and drives the conveyor belt 210 to operate. The mirror-mounted push blocks 211 slide alternately along the moving groove 207, pushing the formed resistors at the bottom of the material groove 215 one by one to the first conveyor belt 303. The limiting frame 305 limits and guides the resistors to prevent deviation during transport. If the conveyor belt 210 becomes loose, the adjusting screw 404 can be rotated to push the tensioning wheel 403 to complete the belt tension adjustment. 3. The resistors are smoothly transferred to the second conveyor belt 304. The infrared counter 307 counts the number of resistors discharged in real time and feeds the results back to the touch screen 302. The conveyor belt speed is adjusted synchronously to achieve cycle matching. When the resistors are moved to the area below the laser trimming machine 310 along the second conveyor belt 304, the laser trimming machine 310 first completes visual scanning and recognition. Then, based on the recognition data, the second servo motor 311 drives the lead screw 312 to rotate, which in turn drives the slider 313 and the movable frame 308 to move along the slide 315. At the same time, the second electric telescopic rod 309 finely adjusts the working position of the laser trimming machine 310 to perform precise laser trimming of the resistors in the conveyor. After trimming, the resistors are transported to the finished product collection station via the second conveyor belt 304. The whole machine can realize integrated continuous operation of alloy resistor stamping, automatic sorting and transfer, online precise trimming and real-time counting. It has a high degree of automation, precise alignment throughout the process, and controllable process, effectively ensuring product processing accuracy and production efficiency.
