Description

Technical Field

[0001] This invention relates to the field of spark plug production equipment technology, and in particular to a spark plug production and processing assembly line device. Background Technology

[0002] Spark plugs are crucial electrical components in the ignition system of gasoline engines. They ignite the compressed gasoline-air mixture in the cylinder, enabling the engine to start and operate. Good spark plug performance—reliable ignition and high ignition energy—ensures the most complete combustion of the gasoline-air mixture in the cylinder, maximizing engine power, reducing fuel consumption, and minimizing emissions. Examples include the Y-type side electrode spark plug (authorization number CN208368945U) and the spark plug with cold-riveted edges using a new sealing material (authorization number CN202721336U). Currently, spark plugs only seal one side of the housing, and there is no dedicated equipment for spark plug sealing. This results in low production efficiency, failing to meet the demand for high-quality spark plugs in large quantities, necessitating improvements. Summary of the Invention

[0003] (a) Technical problems that need to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a spark plug production line device with a reasonable design and simple structure. It has been developed to automatically perform cold riveting sealing on both sides of the spark plug shell components, which does not damage the spark plug itself. This facilitates the production of spark plug products that meet higher quality requirements, greatly improves production efficiency, and is more suitable for mass production.

[0005] (II) Technical problems that need to be solved

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A spark plug manufacturing line includes a sealing ring processing device for installing a sealing ring on the spark plug between an insulator component and a housing component, and a sealing gasket processing device for installing a sealing gasket on the spark plug between a side electrode and a housing component. A material transfer device is provided between the sealing ring processing device and the sealing gasket processing device.

[0008] Preferably, the sealing ring processing equipment includes a machine base, on which a rotating disk is mounted, and a plurality of tooling positions are mounted on the rotating disk. The rotating disk is connected to a turntable power mechanism that drives it to rotate. Along the rotation direction of the rotating disk, a fixed disk is set at the center of the rotating disk. Around the rotating disk, a first wire ring feeding mechanism, a first sealing ring feeding mechanism, a milling mechanism, a milling height detection mechanism, a second wire ring feeding mechanism, a second sealing ring feeding machine, a riveting mechanism, a cleaning mechanism, and a defective rejection mechanism are sequentially installed.

[0009] The cleaning brush cleans the upper part of the spark plug. It should also be noted that the cleaning brush is equipped with an outer cover, which has an inlet and an outlet to prevent the spark plug from being trapped inside and to facilitate observation. The outer cover also prevents excess dirt from being swept away during cleaning. It is important to emphasize that the cleaning drive source is a motor, preferably a stepper motor. The motor is connected to a rotating shaft via a transmission belt, and the cleaning brush is mounted on the rotating shaft. The cleaning brush is a symmetrically distributed bristle brush on the rotating shaft, which facilitates a more thorough cleaning of the upper spark plug sealing gasket.

[0010] The defective rejection mechanism includes a defective rejection fixing frame and a defective rejection bin mounted on the machine base. The defective rejection fixing frame is equipped with a horizontal moving component, a vertical moving component, and a gripper assembly. The defective rejection bin is located to one side of the horizontal moving component. In operation, the vertical moving component moves downwards, and the gripper assembly picks up defective spark plugs transferred from the tooling position on the rotating disc. Then, the vertical moving component moves upwards, and the horizontal moving component moves towards the defective rejection bin. The vertical moving component then moves downwards again, and finally, the gripper assembly on the vertical moving component releases, causing the defective spark plugs to fall into the defective rejection bin. The vertical moving component then moves upwards again, the horizontal moving component returns to its original position, and the vertical moving component moves downwards again, with the gripper assembly picking up defective spark plugs from the tooling position on the rotating disc. This cycle repeats continuously, thus achieving automatic rejection of defective spark plugs.

[0011] Preferably, the material transfer device is mounted on a material transfer base. The material transfer base is equipped with a power source, a mounting frame, and a slide rail. A movable shaft is mounted on the mounting frame, and a gear is mounted on one side of the movable shaft. A rack that slides back and forth is mounted in the slide rail. The rack is fixedly connected to the output shaft of the power source, and the rack meshes with the gear for transmission. The output shaft of the power source drives the rack to slide back and forth in the slide rail, which in turn drives the gear to rotate back and forth. The gear drives the movable shaft to rotate back and forth. A fixed plate is mounted on the movable shaft, and a loading / unloading device is mounted on the fixed plate. The loading / unloading device includes a finger cylinder and a gripper mounted on the fixed plate. It also includes a support rod on each side of the material transfer base located on either side of the mounting frame.

[0012] (III) Technical Effects to be Achieved

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Firstly, the present invention includes a sealing ring processing device for installing a sealing ring on the spark plug between the insulator component and the housing component, and a sealing gasket processing device for installing a sealing gasket on the spark plug between the side electrode and the housing component. A material transfer device is provided between the sealing ring processing device and the sealing gasket processing device. Its design is reasonable and its structure is simple, which is conducive to producing spark plug products with higher qualification requirements, and also greatly improves production efficiency and is more suitable for mass production requirements.

[0015] Secondly, the sealing ring processing equipment of the present invention includes a machine base, on which a rotating disk is mounted, and several tooling positions are mounted on the rotating disk. The rotating disk is connected to a turntable power mechanism that drives it to rotate. Along the rotation direction of the rotating disk, a fixed disk is set at the center of the rotating disk. Around the rotating disk, a first wire ring feeding mechanism, a first sealing ring feeding mechanism, a milling mechanism, a milling height detection mechanism, a second wire ring feeding mechanism, a second sealing ring feeding machine, a riveting mechanism, a cleaning mechanism, and a defective rejection mechanism are installed in sequence. The invention has developed a spark plug housing component that can be automatically cold-riveted and sealed on both sides without damaging the spark plug itself. Moreover, after multiple sealing processes, the sealing performance of the spark plug product is greatly improved. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0039] Example 1: See Figure 1 A spark plug manufacturing line device includes a sealing ring processing device 1 for installing a sealing ring on the spark plug between the insulator component and the housing component, and a sealing gasket processing device 2 for installing a sealing gasket on the spark plug between the side electrode and the housing component. A material transfer device 3 is provided between the sealing ring processing device 1 and the sealing gasket processing device 2. This allows the insulator component on the spark plug to be sealed twice, which greatly improves the performance requirements of the spark plug.

[0040] Example 2: Figure 1 and Figure 2As shown, based on Embodiment 1, the sealing ring processing equipment 1 includes a machine base 10, on which a rotating disc is mounted. Several tooling positions are mounted on the rotating disc, which is connected to a turntable power mechanism that drives its rotation. Along the rotation direction of the rotating disc, a fixed disc is positioned at the center of the rotating disc. Around the rotating disc, in sequence, are installed the following mechanisms: a first wire ring feeding mechanism 11, a first sealing ring feeding mechanism 12, a milling mechanism 13, a milling height detection mechanism 14, a second wire ring feeding mechanism 15, a second sealing ring feeding mechanism 16, a riveting mechanism 17, a cleaning mechanism 18, and a defective rejection mechanism 19. In this embodiment, the milling mechanism 13 and the milling height detection mechanism 14 can be located after the second wire ring feeding mechanism 15. This allows for milling and detection after the second wire ring feeding, making milling more convenient and efficient.

[0041] like Figure 1 As shown, the first wire ring feeding mechanism 11 includes a first wire ring feeding device 111 and a first wire ring clamping device 112, which are distributed sequentially around the rotating disk. The first wire ring feeding device 111 includes a first wire ring support 1111 mounted on a fixed disk, a first X-axis first wire ring guide rail assembly 1112 mounted on the first wire ring support 1111, a first Y-axis first wire ring guide rail assembly 1113 mounted on the first X-axis first wire ring guide rail assembly 1112, a first wire ring clamping device 1114 mounted on the first Y-axis first wire ring guide rail assembly 1113, and a first wire ring vibrating plate 1115. The first wire ring clamping device 1114 installs the first wire ring transmitted from the first wire ring vibrating plate 1115 onto the spark plug at the tooling position. The first wire ring clamping device 112 includes a first wire ring clamping support 1121 mounted on the machine base. A first Y-axis first wire ring clamping guide rail assembly 1122 is mounted on the first Y-axis clamping guide rail assembly 1122. A first wire ring clamping mold seat 1123 is mounted on the first Y-axis clamping guide rail assembly 1122. The first wire ring clamping mold seat 1123 clamps and compacts the spark plug and the first wire ring at the tooling position. The first wire ring clamping mold seat 1123 has a first cavity to accommodate the upper part of the spark plug, thereby realizing the clamping operation.

[0042] like Figure 1As shown, the first sealing ring (sealing filler) feeding mechanism 12 includes a first sealing ring feeding device 121 and a first sealing ring clamping device 122, which are distributed sequentially around the rotating disk. The first sealing ring feeding device 121 includes a first sealing ring support 1211 mounted on a fixed disk, a first X-axis first sealing ring guide rail assembly 1212 mounted on the first sealing ring support 1211, a first Y-axis first sealing ring guide rail assembly 1213 mounted on the first X-axis first sealing ring guide rail assembly 1212, a first sealing ring clamping device 1214 mounted on the first Y-axis first sealing ring guide rail assembly 1213, and a first sealing ring vibrating plate 1215. The first sealing ring clamping device 1214 installs the first sealing ring transmitted from the first sealing ring vibrating plate 1215 onto the spark plug at the tooling position. The first sealing ring clamping device 122 includes a first sealing ring clamping support 1221 mounted on the machine base 10. A first Y-axis first sealing ring clamping guide rail assembly 1222 is mounted on the first Y-axis first sealing ring clamping guide rail assembly 1222. A first sealing ring clamping mold seat 1223 is mounted on the first Y-axis first sealing ring clamping guide rail assembly 1222. The first sealing ring clamping mold seat 1223 clamps and compacts the spark plug and the first sealing ring at the tooling position. The first sealing ring clamping mold seat 1223 has a second cavity to accommodate the upper part of the spark plug, thereby realizing the clamping operation.

[0043] like Figure 1 As shown, the milling mechanism 13 includes a milling base 131 mounted on the machine base 10, a milling up-and-down motion assembly 132 mounted on the milling base 131, a milling rotary motor mounted on the milling up-and-down motion assembly 132, and a milling cutter 133 mounted on the milling rotary motor. In use, the milling cutter 133 moves downward to the upper part of the spark plug, and then the milling rotary motor drives the milling cutter 133 to rotate several times on the upper part of the spark plug, thereby milling off the excess material on the upper part of the spark plug from the first sealing ring installation.

[0044] like Figure 1 and Figure 3As shown, the milling height detection mechanism 14 includes a milling height detection mounting base 141, a milling height detection lifting motion assembly 142 on the milling height detection mounting base 141, a mounting plate 143 on the milling height detection lifting motion assembly 142, a sliding mold 144 and a detection component 145 on the mounting plate 143, and a probe 146 on the sliding mold 144. When the detection component 145 detects the probe 146, it indicates that there is a first sealing ring on the spark plug. This notifies the subsequent second wire ring feeding mechanism 15, second sealing ring feeding machine 16, riveting mechanism 17, cleaning mechanism 18 and transfer device 3 to perform corresponding operations. Otherwise, it notifies the subsequent second wire ring feeding mechanism 15, second sealing ring feeding machine 16, riveting mechanism 17, cleaning mechanism 18 and transfer device 3 not to perform corresponding operations, and the corresponding non-conforming rejection mechanism 19 performs corresponding operations. It should be noted that the sliding mold 144 includes a mold core 1441 that slides up and down on the mounting plate 143. A return spring 1442 is installed on the mold core 1441, and a probe 146 is located on the upper part of the mold core 1441. During use, the detection milling powder lifting and lowering motion assembly 142 drives the mounting plate 143, the sliding mold 144, and the detection component 145 to move downwards as a whole. When there is a second sealing ring on the spark plug, the mold core 1441 moves upwards to the position of the detection component 145. When the detection component 145 detects the probe 146, it indicates that the spark plug has a second sealing ring installed. If the mold core 1441 moves upwards to a position too low or too high above the detection component 145, it indicates that there is no second sealing ring installed or more than one second sealing ring is installed, which is considered a defect. This design facilitates rejection and automated operation. It should also be noted that the probe 146 is an iron ring sleeve located on the upper part of the sliding mold 144. The detection component 145 includes a vertical plate 1451 mounted on the mounting plate 143. The vertical plate 1451 is equipped with a fiber optic sensor 1452 and an indicator light. The fiber optic sensor 1452 and the indicator light are connected. When the indicator light is lit (red), it indicates that the product is qualified. When the indicator light is not lit, it indicates that the product is unqualified.

[0045] like Figure 1As shown, the second wire ring feeding mechanism 15 includes a second wire ring feeding device 151 and a second wire ring clamping device 152, which are distributed sequentially around the rotating disk. The second wire ring feeding device 151 includes a second wire ring support 1511 mounted on a fixed disk, a second X-axis second wire ring guide rail assembly 1512 mounted on the second wire ring support 1511, a second Y-axis second wire ring guide rail assembly 1513 mounted on the second X-axis second wire ring guide rail assembly 1512, a second wire ring clamping device 1514 mounted on the second Y-axis second wire ring guide rail assembly 1513, and a second wire ring vibrating plate 1515. The second wire ring clamping device 1514 installs the second wire ring transmitted from the second wire ring vibrating plate 1515 onto the spark plug at the tooling position. The second wire ring clamping device 152 includes a second wire ring clamping support 1521 mounted on the machine base 10. A second Y-axis second wire ring clamping guide rail assembly 1522 is mounted on the second wire ring clamping support 1521. A second clamping mold seat 1523 is mounted on the second Y-axis clamping guide rail assembly 1522. The second wire ring clamping mold seat 1523 clamps and compacts the spark plug and the second wire ring at the tooling position. The second wire ring clamping mold seat 1523 has a third cavity to accommodate the upper part of the spark plug, thereby realizing the clamping operation.

[0046] like Figure 1As shown, the second sealing ring feeding machine 16 includes a second sealing ring feeding device 161 and a second sealing ring clamping device 162, which are distributed sequentially around the rotating disk. The second sealing ring feeding device 161 includes a second sealing ring support 1611 mounted on a fixed disk, a second X-axis second sealing ring guide rail assembly 1612 mounted on the second sealing ring support 1611, a second Y-axis second sealing ring guide rail assembly 1613 mounted on the second X-axis second sealing ring guide rail assembly 1612, a second sealing ring clamping device 1614 mounted on the second Y-axis second sealing ring guide rail assembly 1613, and a second sealing ring vibrating plate 1615. The second sealing ring clamping device 1614 installs the second sealing ring transmitted from the second sealing ring vibrating plate 1615 onto the spark plug at the tooling position. The second sealing ring clamping device 162 includes a second sealing ring clamping support 1621 mounted on the machine base 10. A second Y-axis second sealing ring clamping guide rail assembly 1622 is mounted on the second Y-axis first sealing ring clamping guide rail assembly 1622. A second sealing ring clamping mold seat 1623 is mounted on the second Y-axis first sealing ring clamping guide rail assembly 1622. The second sealing ring clamping mold seat 1623 clamps and compacts the spark plug and the second sealing ring at the tooling position. The second sealing ring clamping mold seat 1623 has a fourth cavity to accommodate the upper part of the spark plug, thereby realizing the clamping operation.

[0047] like Figure 1 As shown, the riveting mechanism 17 includes a riveting support base 171, a riveting drive source 172 mounted on the support base 171, and a cylinderless mold 173 mounted on the drive source 172. The cylinderless mold 173 performs a pressing operation on the upper part of the spark plug. The riveting drive source 172 is a pneumatic-hydraulic booster cylinder. The cylinderless mold 173 has mounting grooves distributed along its axial direction to accommodate the upper part of the spark plug.

[0048] like Figure 1 and Figure 18As shown, the cleaning mechanism 18 includes a cleaning seat 181 mounted on a fixed plate. A cleaning drive source 182 is mounted on the cleaning seat 181, and a cleaning brush 183 is mounted on the cleaning drive source 182. The cleaning brush 183 cleans the upper part of the spark plug. It should also be noted that the cleaning brush 183 is surrounded by an outer cover 184, which has an inlet and an outlet to prevent the spark plug from being trapped inside and to facilitate observation. The outer cover 184 also prevents excess dirt from being swept away during cleaning. It is important to emphasize that the cleaning drive source 182 is a motor, preferably a stepper motor. The motor is connected to a rotating shaft via a transmission belt, and the cleaning brush 183 is mounted on the rotating shaft. The cleaning brush 183 is a symmetrically distributed bristle brush mounted on the rotating shaft, which facilitates a more thorough cleaning of the upper spark plug sealing gasket.

[0049] like Figure 1 As shown, the defective rejection mechanism 19 includes a defective rejection fixing frame 191 and a defective rejection bin 192 mounted on the machine base 10. The defective rejection fixing frame 191 is equipped with a horizontal running component 193, a vertical moving component 194, and a gripper assembly 195. The defective rejection bin 192 is located on one side of the horizontal running component 193. In use, the vertical moving component 194 moves downwards, and the gripper assembly 195 grabs the defective spark plugs transferred from the tooling position on the rotating disc. Then, the vertical moving component 194... The spark plug moves upwards, then moves towards the defective rejection bin 122 via the horizontal movement component 193. It then moves downwards via the vertical movement component 194. Finally, the gripper component 195 on the vertical movement component 194 releases, and the defective spark plug falls into the defective rejection bin 192. Then, the vertical movement component 194 moves upwards, the horizontal movement component 193 returns to its original position, and the vertical movement component 194 moves downwards again. The gripper component 195 then grabs the defective spark plug from the tooling position on the rotating disc. This cycle repeats, thus achieving automatic rejection of defective spark plugs.

[0050] In this invention, the second sealing ring (sealing filler) refers to a pink ring made primarily of talc powder. The fiber optic sensor in this invention also employs an infrared detector.

[0051] Example 3: Figure 4 and Figure 5As shown, based on Embodiment 1 or Embodiment 2, the material transfer device 3 is set on the material transfer base 30. The material transfer base 30 is provided with a power source 31, a mounting frame 32 and a slide rail seat 33. The mounting frame 32 is provided with a movable shaft 34. A gear 35 is provided on one side of the movable shaft 34. A rack 36 that slides back and forth is provided in the slide rail seat 33. The rack 36 is fixedly connected to the output shaft of the power source 31. The rack 36 and the gear 35 are meshed and connected for transmission. The output shaft of the power source 31 drives the rack 36 to slide back and forth in the slide rail seat 33. The rack 36 drives the gear 35 to rotate back and forth. The gear 35 drives the movable shaft 34 to rotate back and forth. A fixed plate 37 is provided on the movable shaft 34. A loading and unloading device 38 is provided on the fixed plate 37. The loading and unloading device 38 includes a finger cylinder and a gripper provided on the fixed plate 37. It also includes a support rod 39 on each of the transfer bases 30 located on both sides of the mounting bracket 32. The support rod 39 can support and buffer the fixed plate 37 after it has been rotated 180 degrees, thereby better enabling the operation of picking up and removing spark plugs. The power source 31 can be a cylinder for ease of implementation.

[0052] Example 4: Figure 6 , Figure 7 and Figure 8 As shown, based on Embodiment 1, Embodiment 2, or Embodiment 3, the gasket processing equipment 2 includes a turntable feeding mechanism 21, with multiple feeding fixtures 22 arranged in a ring for rotating and conveying workpieces to the aforementioned mechanisms for assembly. Along the periphery of the turntable feeding mechanism 21, a gasket loading mechanism 23, a gasket detection mechanism 24, a compaction mechanism 25, a spark plug alignment mechanism 26, and a material transfer mechanism 27 are arranged in sequence. This fully automates the process of installing the spark plug, attaching the gasket to the spark plug, checking the gasket's quality, pressing the gasket onto the spark plug, and finally removing the processed spark plug. This significantly improves the level of automation, better meets the requirements of mass production in modern manufacturing enterprises, and also greatly reduces labor costs.

[0053] like Figure 8 As shown, the turntable feeding mechanism 21 includes a turntable support frame 212, a turntable rotary motor 213, a divider, an outer ring plate 214, and a turntable body 215. The turntable body 215 and the outer ring plate 214 are arranged from top to bottom on the turntable support frame 212. The outer ring plate 214 is located on the turntable support frame 212, and the turntable body 215 is rotatably mounted on the turntable support frame 212. The turntable rotary motor 213 and the divider are located on the turntable support frame 212. The turntable rotary motor 213 is driven and connected to the input end of the divider, and the output end of the divider is driven and connected to the turntable. Multiple feeding fixtures 211 are arranged circumferentially on the turntable body 215. This arrangement is conducive to achieving automatic operation, improving the level of automation and production efficiency, and reducing labor costs.

[0054] like Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the gasket feeding mechanism 23 includes a gasket vibrating plate 231 and a gasket feeding device 232 arranged around the turntable feeding mechanism 21. The gasket vibrating plate 231 and the gasket feeding device 232 are connected through a transmission channel 233. The gasket is installed onto the spark plug in the feeding fixture 22 of the turntable feeding mechanism 21 by the gasket feeding device 232. It should be noted that the sealing gasket feeding device 232 includes a main support 2321 and a secondary support 2322. The main support 2321 is equipped with an X-axis slide rail assembly 2323, the X-axis slide rail assembly 2323 is equipped with a Y-axis slide rail assembly 2324, and the Y-axis slide rail assembly 2324 is equipped with a clamping component 2325. The secondary support 2322 is equipped with a horizontal pushing component 2326, and the horizontal pushing component 2326 is connected to a material carrier plate 2327. The material carrier plate 2327 has a material loading groove 2328. In the initial state, the material loading groove 2328 of the material carrier plate 2327 is aligned with the outlet end of the transmission channel 233, which enables the transmission of the sealing gasket. Then, it is pushed by the horizontal pushing component 2326 and clamped and installed onto the spark plug of the turntable feeding mechanism 21 by the clamping component 2325. It should also be noted that the sub-support 2322 is equipped with a sensor for detecting whether there is a sealing gasket on the material loading groove 2328 in the initial state of the material carrier 2327. The sensor is connected to a horizontal pushing component 2326, which facilitates automatic pushing. When a sealing gasket is detected in the material loading groove 2328, the sensor notifies the horizontal pushing component 2326 to push the material carrier 2327, which is then gripped by the clamping component 2325. The horizontal pushing component 2326 then returns the material carrier 2327 to its initial state, and this cycle repeats. The sensor used is a fiber optic sensor or similar. Both the X-axis slide rail assembly 2323 and the Y-axis slide rail assembly 2324 use cylinders. The X-axis slide rail assembly 2323 and the Y-axis slide rail assembly 2324 can move the clamping component 2325 left and right and up and down. The clamping component 2325 uses a finger cylinder and a gripper to grip the sealing gasket. The sealing gasket can be installed on the spark plug via the sealing gasket feeding mechanism 23.

[0055] like Figure 8 and Figure 11As shown, the gasket detection mechanism 24 includes a stand 241 arranged around the turntable feeding mechanism 21. A lifting motion component 242 is arranged on the stand 241, and a mounting block 243 is arranged on the lifting motion component 242. A detection component 244 and a sensing component 245 are arranged on the mounting block 243. The detection component 244 detects the gasket on the spark plug of the feeding fixture 22 in the turntable feeding mechanism 21. If there is a gasket, the sensing component 245 receives the information from the detection component 244 and uses the sensing component 245 to show whether the gasket on the spark plug in the feeding fixture 22 is qualified. If the gasket on the spark plug in the feeding fixture 22 is qualified, the compaction mechanism 25, the spark plug alignment mechanism 26 and the material transfer mechanism 27 will be notified to perform the compaction operation. If the gasket on the spark plug in the feeding fixture 22 is unqualified, the compaction mechanism 25, the spark plug alignment mechanism 26 and the material transfer mechanism 27 will not be notified to perform the compaction operation. The lifting motion component 242 uses a dual-axis cylinder. The detection component 244 includes a mold 2441 mounted on the mounting block 243, a return spring 2442 mounted on the mold 2441, and a groove at the lower end of the mold 2441 for accommodating the upper part of the spark plug. The mold 2441 moves up and down on the mounting block 243 and is reset by the return spring 2442. The sensing component 245 includes a collar 2451 mounted on the detection component 244 and a vertical plate 2452 mounted on the mounting block 243. The vertical plate 2452 is equipped with a fiber optic sensor 2453 for sensing the collar 2451 and an indicator light. The fiber optic sensor 2453 and the indicator light are connected. In use, when the spark plug containing the sealing gasket in the feeding fixture 22 of the rotary feeding mechanism 21 is brought to a position below the detection component 244, and then the lifting motion component 242 brings the mounting plate 243, detection component 244, and sensing component 245 downward as a whole, the groove of the mold 2441 in the detection component 244 will fit down from the top of the spark plug. When there is a sealing gasket, the mold 2441 will bring the collar 2451 upward to the position of the fiber optic sensor 2453. The fiber optic sensor 2453 will sense the collar 2451, and the indicator light will also... The indicator light will illuminate, indicating that there is a qualified sealing gasket on the spark plug. The subsequent compaction mechanism 25, spark plug alignment mechanism 26, and transfer mechanism 27 will then operate sequentially to compact the spark plug. If there is no or more than one sealing gasket, the mold 2441 will cause the race 2451 to move too low or too high. In this case, the fiber optic sensor 2453 will not detect the race 2451, and the indicator light will not illuminate. This indicates that there is no qualified density gasket on the spark plug, and the subsequent compaction mechanism 25, spark plug alignment mechanism 26, and transfer mechanism 27 will not operate.

[0056] like Figure 8 and Figure 12As shown, the compaction mechanism 25 includes a base 251 disposed around the turntable feeding mechanism 21. A vertical motion component 252 is mounted on the base 251, and a forming mold 253 is connected to the vertical motion component 252. The forming mold 253 has an inner groove 254 for fitting over the upper part of the spark plug. Several positioning protrusions 255 are distributed on the inner wall of the inner groove 254; in this embodiment, three positioning protrusions 255 are used. These positioning protrusions 255 facilitate pressing the sealing gasket firmly onto the spark plug, resulting in a more compact press. The vertical motion component 252 is a cylinder.

[0057] like Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, the spark plug alignment mechanism 26 includes a fixed frame 261 disposed around the turntable feeding mechanism 21. A vertical slide rail assembly 262 is disposed on the fixed frame 261. A horizontal slide rail assembly 263 is disposed on the vertical slide rail assembly 262. A slide rail seat 264 is disposed on the horizontal slide rail assembly 263. A reciprocating rack 265 is disposed on the slide rail seat 264. A fixed seat 266 is fixedly connected to the slide rail seat 264. A rotating gear 267 is installed in the fixed seat 266. The rotating gear 267 meshes with the rack 265 for transmission. The rotating gear 267 is connected to a model 268. A cavity for accommodating the upper part of the spark plug is axially distributed at the center of the model 268. A paddle 269 (which may also protrude from the outer surface of the model 268) is disposed on the inner wall of the cavity. In use, the vertical slide rail assembly 262 moves up and down to fit over the spark plug, while the horizontal slide rail assembly 263 drives the rack 265 to move horizontally on the slide rail seat 264. The rack 265 drives the rotating gear 267 to rotate, which in turn drives the model 268 to rotate. The model 268 then rotates via a lever, causing the spark plug inside the cavity to rotate. At this point, the side electrode is positioned at a suitable angle in the upward direction, and the spark plug is then transferred to the next production stage via the transfer mechanism 27. The vertical slide rail assembly 262 is a Y-axis slide rail assembly, and the horizontal slide rail assembly 263 is an X-axis slide rail assembly.

[0058] like Figure 13 , Figure 15 and Figure 16As shown, the material transfer mechanism 27 includes a support base 271 disposed around the turntable feeding mechanism 21. A transverse slide rail assembly 272 is mounted on the support base 271. A longitudinal slide rail assembly 273 is mounted on the transverse slide rail assembly 272. A rotary cylinder 274 is mounted on the longitudinal slide rail assembly 273. A mechanical gripper 275 is mounted on the rotary cylinder 274. The mechanical gripper 275 moves horizontally and vertically via the transverse slide rail assembly 272 and the longitudinal slide rail assembly 273, thereby gripping the spark plug and transferring it to the next process step via the slide rail assembly 272 and the longitudinal slide rail assembly 273. The mechanical gripper 275 includes a finger cylinder and a robotic arm. The transverse slide rail assembly 272 uses an X-axis slide rail assembly, and the longitudinal slide rail assembly 273 uses a Y-axis slide rail assembly. Figure 1 and Figure 7 As shown, it's also worth noting that the next step in the mechanical gripper 275's grasping process involves a bending machine and a cutting machine. The authorized publication number CN215279469U, a Chinese utility model patent successfully applied for by Ningbo Yuanshuai Auto Parts Co., Ltd., discloses a pre-bending and shaping machine for the side electrode of a spark plug, which includes a bending machine and a cutting machine, as already described in detail and known to those skilled in the art, will not be elaborated upon here. The installed spark plug is transferred to the bending machine via the material transfer mechanism 7, and finally, the side electrode of the spark plug is bent.

[0059] Example 5: Based on Example 1, Example 2, Example 3, or Example 4, this example further includes a controller connected to a sealing ring processing device 1, a sealing gasket processing device 2, and a material transfer device 3. This facilitates adjustment and control. The controller in this invention can be a controller containing a microcontroller or PLC; such technology is well-known to those skilled in the art and will not be described in detail here.

[0060] The fully automated cold riveting process used in this invention reduces damage to the spark plug itself and makes it easier for spark plug products to meet standards.

[0061] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts and rivets that are mature in the existing technology. The internal components of the switches and processors adopt conventional models in the existing technology, and their internal structures are existing technical structures. Workers can complete normal operation by referring to existing technical manuals. In addition, the circuit connection adopts conventional connection methods in the existing technology, and will not be described in detail here.

[0062] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this invention.
