Description

Technical Field

[0001] This utility model relates to the field of automatic assembly, conditioning, testing and production of ESC sensors, and in particular to an automatic assembly, conditioning and testing line for ESC sensors. Background Technology

[0002] ESC sensors are increasingly widely used in the automotive industry. While the demand for ESC sensors is increasing, the quality requirements are also rising, leading to increasingly fierce competition among ESC sensor manufacturers. The ESC sensor manufacturing process involves assembling components such as the main body, PFC, housing, and springs, followed by post-assembly adjustments. This process involves numerous assembly steps and welding processes. Current production processes rely heavily on manual labor in assembly and welding, resulting in high production costs, difficulty in improving production efficiency, and inconsistent product quality due to staff turnover and individual differences. Utility Model Content

[0009] Furthermore, the welding mechanism includes a welding assembly for welding the pre-pressed assembled product, a welding rotation module for transferring and positioning the product and driving its rotation to cooperate with the welding assembly in completing the welding, and an auxiliary rotation module that, during the transfer of the product by the welding rotation module, lifts the pre-pressed assembled product from the corresponding loading fixture and supports the lower end of the product as it rotates with the welding rotation module. The welding assembly includes a seventh horizontal drive mechanism located on one side of the turntable mechanism, an eighth horizontal drive mechanism driven by the seventh horizontal drive mechanism to move horizontally relative to the corresponding loading fixture on the turntable mechanism, and a... The system comprises an eighth horizontal drive mechanism driving a fourth vertical drive mechanism to move horizontally along the direction perpendicular to the eighth horizontal drive mechanism, a first rotary drive mechanism driven by the fourth vertical drive mechanism to move vertically, and a laser welding machine whose angle is adjusted by the first rotary drive mechanism in the vertical direction.

The turntable mechanism and the corresponding loading unit have welding lifting holes at positions corresponding to the welding lifting rod, allowing the welding lifting rod to move up and down. This automated process completes 360-degree welding of the product's circumference. The bottom lifting is accompanied by rotation, preventing the pre-pressed assembled products from falling off, dispersing, or shifting during welding, resulting in better welding quality.

[0010] Furthermore, the elasticity testing mechanism includes a detection lifting mechanism for lifting welded products within the corresponding set of loading fixtures on the jacking turntable mechanism, a positioning clamping mechanism for holding the products lifted by the detection lifting mechanism, and a spring detection assembly for detecting each spring on the products held by the positioning clamping mechanism.

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 An automated assembly, conditioning, and testing line for ESC sensors is shown, comprising sensor FPC assembly equipment for automatically assembling sensor semi-finished products and a conditioning and testing line for conditioning the assembled and welded products. The line is characterized by further including assembly and welding equipment that interfaces with the sensor PFC assembly equipment and the conditioning and testing line. The assembly and welding equipment includes a turntable mechanism 1001 and multiple assembly loading units 1002 disposed on the turntable mechanism 1001 and driven and positioned by the turntable mechanism 1001. Each assembly loading unit 1002 is provided with at least one cavity for placing a housing and at least one cavity for placing a sensor semi-finished product. The assembly and welding equipment also includes a main body feeding mechanism disposed around the turntable mechanism 1001 that automatically feeds housings and sensor semi-finished products sequentially into the assembly loading units 1002. 1100, a spring assembly mechanism for automatically assembling springs inside the housing of the assembly loading device 1002; 1200, a semi-finished product assembly mechanism for automatically assembling sensor semi-finished products inside the housing with assembled springs; 1300, a flipping mechanism for automatically pre-pressing and flipping the housing with assembled sensor semi-finished products; 1400, a welding mechanism for automatically welding the pre-pressed and flipped sensor semi-finished products and the housing with springs into a sensor product; 1500, an elasticity testing mechanism for automatically testing the elasticity of the springs inside the welded sensor product; 1600, a resistance testing mechanism for automatically testing the resistance of the welded sensor product; 1700, a marking mechanism for automatically marking the sensor product after resistance testing; and 1900, an automatic unloading mechanism for automatically unloading the marked sensor product.

[0037] In this specific embodiment, the conditioning and testing line includes an airtightness testing device for automatically performing airtightness testing on sensor products, a tray placement device for automatically scanning and placing the sensor products on trays after airtightness testing, a tray transfer mechanism for transferring the trayed sensor products, and a room temperature conditioning device, a high temperature conditioning device, a low temperature conditioning and testing device, a high temperature testing device, a cooling line, a room temperature testing device, and an inspection and collection device for sequentially performing batch automatic room temperature conditioning, high temperature conditioning, low temperature conditioning and testing, high temperature testing, cooling, room temperature testing, appearance inspection, and material collection on the trayed sensor products on the tray transfer mechanism. In this specific embodiment, after the airtightness testing equipment performs an airtightness test on the finished product automatic unloading mechanism 1900, the good products are transferred to the automatic barcode scanning and tray placement equipment. The barcode scanner on the automatic barcode scanning and tray placement equipment scans the good products after the airtightness test and places them into a material tray containing multiple products. The material tray transmission mechanism is a roller transmission mechanism, which transmits the material tray through a preset room temperature conditioning equipment, a preset high temperature conditioning equipment, a preset low temperature conditioning testing equipment, a preset high temperature testing equipment, a preset air-cooled cooling line, a preset room temperature testing equipment, and finally a detection and receiving equipment for product appearance inspection and collection. This process enables batch automatic room temperature conditioning, high temperature conditioning, low temperature conditioning testing, high temperature testing, cooling, room temperature testing, appearance inspection, and collection of sensor products with high efficiency. The marking mechanism 1800 is an automatic labeling machine purchased from the market; the turntable mechanism 1001 is a double-layer turntable purchased from the market, which includes a fixed upper plate and a rotating lower plate for transport.

[0038] In practice, the main feeding mechanism 1100 automatically feeds the manually batch-fed housings and the sensor semi-finished units transmitted from the sensor FPC assembly equipment into the corresponding placement slots of the loading fixture 1002 on the turntable mechanism 1001; the turntable mechanism 1001 transports this loading fixture 1002 to the corresponding position of the spring assembly mechanism 1200, where the spring assembly mechanism 1200 automatically assembles the springs within the housing of the loading fixture 1002; the turntable mechanism 1001 transports this loading fixture 1002 to the semi-finished unit... At the corresponding position of the finished product assembly mechanism 1300, the semi-finished product assembly mechanism 1300 automatically assembles the sensor semi-finished product inside the housing with the assembled spring; the turntable mechanism 1001 transports this set of loading devices 1002 to the corresponding position of the flipping mechanism 1400, and the flipping mechanism 1400 automatically pre-presses and flips the housing with the assembled sensor semi-finished product; the turntable mechanism 1001 transports this set of loading devices 1002 to the corresponding position of the welding mechanism 1500, and the welding mechanism 1500 automatically welds the pre-pressed and flipped sensor semi-finished product and... A spring-loaded housing is welded into a sensor product. A turntable mechanism 1001 transports this loading device 1002 to the corresponding position of the elasticity testing mechanism 1600, which automatically performs an elasticity test on the spring inside the welded sensor product. The turntable mechanism 1001 then transports this loading device 1002 to the corresponding position of the resistance testing mechanism 1700, which automatically performs resistance testing on the welded sensor product. The turntable mechanism 1001 then transports this loading device 1002 to the corresponding position of the marking mechanism 1800, which automatically marks the sensor product after resistance testing. The turntable mechanism 1001 then transports this loading device 1002 to the corresponding position of the automatic finished product unloading mechanism 1900, which automatically unloads the marked sensor product. The automatic finished product unloading mechanism 1900 transfers the finished product to the conditioning and testing line, which connects to the automatic finished product unloading mechanism 1900 to perform conditioning and testing on the sensor product.

[0039] The entire assembly, welding, testing, and conditioning of sensor products is completed automatically, with high speed, high efficiency, and stable quality.

[0040] Based on the above, such as Figure 1 and Figure 2 As shown, the main loading mechanism 1100 includes a shell feeding mechanism 1110, a semi-finished product loading and conveying mechanism, a loading transfer and implantation mechanism 1120 that transfers the shells and semi-finished products on the shell feeding mechanism 1110 and the semi-finished product loading and conveying mechanism to the corresponding loading container 1002, and a shell loading detection mechanism 1130 located on one side of the shell feeding mechanism 1110 within the moving range of the loading transfer and implantation mechanism 1120.

[0041] In this specific embodiment, the shell feeding mechanism 1110 includes two support plates vertically arranged side-by-side outside the turntable mechanism 1001, two first horizontal slide rail assemblies horizontally arranged corresponding to each other on the inner sidewalls of the two support plates, a first sliding plate horizontally slidably mounted on the two first horizontal slide rail assemblies, a first horizontal drive mechanism located outside the support plates and connected to drive the first sliding plate to slide horizontally, two second horizontal slide rail assemblies horizontally arranged corresponding to each other inside the two support plates and located below the two first horizontal slide rail assemblies, a second sliding plate horizontally slidably mounted on the two second horizontal slide rail assemblies, a second horizontal drive mechanism located inside the support plates and connected to drive the second sliding plate to slide horizontally, and a plurality of shell storage trays for batch storage of shells. Both the first and second sliding plates are provided with limiting mechanisms for limiting the shell storage trays. The shell storage trays in the shell feeding mechanism 1110, suitable for batch storage of shells, can position the shells for storage. The storage direction facilitates material retrieval for the next assembly step. The housing feeding mechanism 1110 operates in a similar manner to the core feeding mechanism in the sensor FPC assembly equipment. Both the first and second horizontal drive mechanisms are rodless cylinder assemblies. The loading and transfer implantation mechanism 1120 consists of a four-axis robotic arm with a positioning industrial camera and a gripper cylinder assembly driven by the four-axis robotic arm to move vertically and horizontally and rotate. The gripper cylinder assembly includes a gripper cylinder and a first contoured claw finger driven by the gripper cylinder to hold the housing. The housing loading detection mechanism 1130 uses an industrial camera to detect the presence and orientation of the housing, facilitating corresponding adjustments by the loading and transfer implantation mechanism 1120. The semi-finished product loading and transfer mechanism transfers the semi-finished products assembled by the sensor FPC assembly equipment in the previous process to the working range of the loading and transfer implantation mechanism 1120, which then transplants the semi-finished products into the assembly loading fixture 1002. This automated loading of sensor housings and semi-finished products is highly efficient and stable.

[0042] Based on the above, such as Figure 1 , Figure 3 and Figure 4As shown, the spring assembly mechanism 1200 includes at least one spring feeding mechanism 1210 for feeding springs and at least one spring implantation positioning module 1220 for aligning and implanting springs. The spring feeding mechanism 1210 includes a spring vibrating feeding disc 1211 for feeding springs, a spring blowing mechanism for blowing out springs fed by the spring vibrating feeding disc 1211, a spring blowing pipe connected to the spring blowing mechanism for driving the spring implantation positioning module 1220, and a spring discharge head 1212 connected to the end of the spring blowing pipe. The spring discharge head 1212 is fixedly mounted on the spring implantation positioning module 1220 and is driven by the spring implantation positioning module 1220 to move relative to the corresponding assembly loading device 1002. The spring implantation positioning module 1220 includes components located on the turntable mechanism 100. 1. A first fixed bracket assembly 1221 on one side; a third horizontal drive mechanism 1222 on the first fixed bracket assembly 1221; a fourth horizontal drive mechanism 1223 on the third horizontal drive mechanism 1222 and driven by the third horizontal drive mechanism 1222 to move horizontally relative to the loading device 1002 on the turntable mechanism 1001; a first vertical drive mechanism 1224 on the fourth horizontal drive mechanism 1223 and driven by the fourth horizontal drive mechanism 1223 to move in a direction perpendicular to the fourth horizontal drive mechanism 1223; a first vertical fixed plate 125 on the first vertical drive mechanism 1224 and driven by the first vertical drive mechanism 1224 to move vertically; an industrial camera for positioning and observation and a discharge head fixing block 1226 for fixing the spring discharge head 1212 on the first vertical fixed plate 125.

[0043] In this specific embodiment, the third horizontal drive mechanism 1222, the fourth horizontal drive mechanism 1223, and the first vertical drive mechanism 1224 are all linear drive mechanisms composed of a servo motor and a ball screw slide module. In specific implementations, the third horizontal drive mechanism 1222, the fourth horizontal drive mechanism 1223, and the first vertical drive mechanism 1224 can also be linear drive mechanisms such as linear motor assemblies or stroke-controllable cylinder assemblies. High precision and rapid positioning and movement of the spring discharge head 1212 to the preset implantation position within the housing of the corresponding loading unit 1002 are achieved. The spring vibration feed plate 1211 is a commercially available spring vibration feed plate of suitable model. The spring blowing mechanism is an external air pump mechanism with the air outlet fixed to the spring vibration feed plate. The spring blowing pipe is a transparent spring guide feed pipe, facilitating observation of the feeding situation during use. The spring discharge head 1212 is a straight guide tube fixed to the spring implantation positioning module 1220, facilitating the spring's implantation into the housing of the corresponding loading unit 1002.

[0044] Based on the above, such as Figure 1 , Figures 5 to 9As shown, the semi-finished product assembly mechanism 1300 includes an assembly positioning mechanism 1310, a pre-compression assembly mechanism 1320, a defective product temporary storage mechanism 1330, and an assembly inspection mechanism 1340. The assembly positioning mechanism 1310 is located on one side of the turntable mechanism 1001 and is opposite to the corresponding loading device 1002 on the turntable mechanism 1001 that needs to be assembled into semi-finished products. The pre-compression assembly mechanism 1320 is used to assemble, pre-compress, and transfer the assembled and pre-compressed products. The assembly inspection mechanism 1340 is located within the product transfer range of the pre-compression assembly mechanism 1320 and performs appearance inspection on the products transferred by the pre-compression assembly mechanism 1320. The defective product temporary storage mechanism 1330 is located within the product transfer range of the pre-compression assembly mechanism 1320 and is used to temporarily store defective products after assembly.

[0045] In this specific embodiment, the assembly inspection mechanism 1340 is an industrial camera that performs visual inspection on the lower end of the pre-compressed product transferred by the pre-compress assembly mechanism 1320 above it. In practice, the assembly positioning mechanism 1310 positions and fixes the housing within the corresponding assembly loading fixture 1002 on the turntable mechanism 1001 that requires semi-finished product assembly. The pre-compress assembly mechanism 1320 clamps the upper end of the sensor semi-finished product within the corresponding assembly loading fixture 1002 and transfers the sensor semi-finished product to the assembled spring correspondingly implanted within the assembly loading fixture 1002. Inside the housing, the sensor semi-finished product and the housing are pre-compressed. After the pre-compression assembly is completed, the pre-compression assembly mechanism 1320 clamps the pre-compressed product and passes it through the assembly inspection mechanism 1340. The assembly inspection mechanism 1340 inspects the appearance of the pre-compressed product. Based on the inspection results fed back by the assembly inspection mechanism 1340, the pre-compression assembly mechanism 1320 places good products back into the corresponding loading container 1002 and transfers them to the next process by the turntable mechanism 1001. Defective products are transferred to the defective product temporary storage mechanism 1330, where personnel will collect and transfer them later. The assembly, pre-compression, and preliminary inspection of the sensor semi-finished product and the housing with springs are completed automatically, with high efficiency and strong stability.

[0046] The assembly positioning mechanism 1310 includes a fifth horizontal drive mechanism 1311 and at least one first housing clamping mechanism 1312 driven by the fifth horizontal drive mechanism 1311 to move horizontally relative to the inner housing of the corresponding assembly loading device 1002. The first housing clamping mechanism 1312 is provided with a second contoured clamping finger 1313 driven by it to clamp the middle of the outer surface of the housing. In this specific embodiment, the assembly loading device 1002 has two housing placement holes and two sensor semi-finished product placement holes. The fifth horizontal drive mechanism 1311 is a slide cylinder. The first housing clamping mechanism 1312 has two clamping cylinders, each corresponding to the inner housing of the two housing placement holes on the assembly loading device 1002. Both first housing clamping mechanisms 1312 are driven to move horizontally by the fifth horizontal drive mechanism 1311. The second contoured clamping finger 1313 clamps the middle of the housing in the assembly loading device 1002, and makes room while ensuring effective positioning and fixation, so as to facilitate the pre-compression assembly mechanism 1320 to perform assembly pre-compression operation. It has a simple structure, stable operation, and minimal mutual interference.

[0047] The pre-compression assembly mechanism 1320 includes a multi-axis robotic arm, a first fixing block 1321, a second housing clamping mechanism 1322, a positioning observation mechanism 1323, and a first pre-compression structure 1350. The first fixing block 1321 is fixedly mounted on the multi-axis robotic arm and is driven by the multi-axis robotic arm to move in the horizontal and vertical directions and rotate in the horizontal direction. The second housing clamping mechanism 1322 and the positioning observation mechanism 1323 are both fixedly mounted on the first fixing block 1321. The second housing clamping mechanism 1322 is provided with a third contoured gripper 1324 driven by it to clamp the upper part of the outer surface of the housing and the upper part of the sensor semi-finished product. The first pre-compression structure 1350 is mounted on the second housing clamping mechanism 1322 and one end extends to the upper side of the clamping position of the third contoured gripper 1324, which can apply elastic pressure to the upper end of the product. In this specific implementation, the positioning observation mechanism 1323 is an industrial camera used for observation and positioning; the second housing clamping mechanism 1322 is a gripper cylinder; in the specific implementation, the multi-axis robotic arm, under the positioning of the positioning observation mechanism 1323, drives the second housing clamping mechanism 1322 to move (when there is a difference in the assembly angle between the sensor semi-finished product and the housing, the multi-axis robotic arm drives the second housing clamping mechanism 1322 to rotate and align), and the upper end of the sensor semi-finished product is clamped by the third contouring gripper finger 1324 (at this time, the first pre-compression structure 1350 also applies a spring force to the upper end of the sensor semi-finished product, but the spring force is extremely small and does not cause any impact) to transfer the sensor semi-finished product into the housing. After the sensor semi-finished product enters the housing, the third contouring gripper 1324 separates outwards, releasing its grip and allowing it to fall into the corresponding housing. The multi-axis robotic arm drives the first pre-compression structure 1350 to continue moving downwards. The portion of the first pre-compression structure 1350 above the gripping position of the third contouring gripper 1324 continues to elastically pre-compress the sensor semi-finished product and the housing. After moving down to the preset position and completing the pre-compression, the multi-axis robotic arm drives the second housing clamping mechanism 1322 to move upwards to the preset position. The second housing clamping mechanism 1322 can then drive the third contouring gripper 1324 to clamp the upper end of the pre-compressed product, which is then transferred by the multi-axis robotic arm. Automated elastic pre-compression effectively reduces damage to the product during pre-compression.

[0048] The first pre-compression structure 1350 includes a first pre-compression fixing block 1351, a second pre-compression fixing block 1352, a first pre-compression rod 1353, and a first pre-compression spring 1354. The first pre-compression fixing block 1351 is fixed to the second housing clamping mechanism 1322. The second pre-compression fixing block 1352 is fixed to the lower end of the first pre-compression fixing block 1351 and one end extends to the upper side of the clamping position of the third contoured finger 1324. The second pre-compression fixing block 1352 and the third contoured finger... A vertically penetrating first limiting hole is provided at the clamping position 1324. The first preload rod 1353 is disposed within the first limiting hole, and its vertical movement is limited by the first limiting hole. Limiting caps with a vertical drop greater than the first limiting hole are provided at both the upper and lower ends of the first preload rod 1353. The first preload spring 1354 is sleeved on the outer surface of the first preload rod 1353 and is located between the limiting cap at the lower end of the first preload rod 1353 and the lower surface of the second preload fixing block 1352. This simple structure achieves preload on the assembled product.

[0049] The defective product temporary storage mechanism 1330 includes a rectangular temporary storage tray 1331 and a temporary storage fixing bracket 1332. The rectangular temporary storage tray 1331 is evenly provided with multiple defective temporary storage slots 1333 for temporarily storing defective products after pre-compression assembly of the housing and sensor semi-finished products. A temporary storage limiting plate 1334 is provided at the upper end of the temporary storage fixing bracket 1332. Multiple right-angle limiting blocks 1335 are provided around the periphery of the temporary storage limiting plate 1334 to limit the outer corners of the rectangular temporary storage tray 1331. The temporary storage limiting plate 1334 has clearance notches corresponding to the defective temporary storage slots 1333 on the rectangular temporary storage tray 1331. The rectangular temporary storage tray 1331 is easy to place and remove, allowing for the batch removal of defective products and the replacement of empty rectangular temporary storage trays 1331.

[0050] A pre-compression storage block 1360 is provided on the outer edge of one end of the temporary storage limiting plate 1334. The pre-compression storage block 1360 is provided with a plurality of transition storage acupoints 1361 for temporarily storing the product after the shell and sensor semi-finished products are assembled and pre-compressed. The transition storage acupoints 1361 extend vertically and are provided with a photoelectric sensor 1362 at the bottom to detect whether the product is placed in. When the product after the shell and sensor semi-finished products are assembled and pre-compressed is placed in the transition storage acupoints 1361, the middle part is located in the transition storage acupoints 1361 and the upper part is located on the upper side of the transition storage acupoints 1361. The transition storage acupoints 1361 are higher than the right angle limiting block 1335. The width of the pre-compression storage block 1360 is less than the maximum distance between the fingers after the second shell clamping mechanism 1322 drives the third contoured clamping finger 1324 to separate. In specific implementation, when the sensor semi-finished product and housing are defective under the inspection of the assembly inspection mechanism 1340 but can be pre-pressed again, the pre-pressing assembly mechanism 1320 transfers the product to the transition storage cavity 1361 for pre-pressing again, and then transfers it to the assembly inspection mechanism 1340 for inspection. Based on the inspection results, the pre-pressed product is returned to the corresponding loading container 1002 and transferred to the next process by the turntable mechanism 1001, or placed in the rectangular temporary storage tray 1331 for subsequent processing. Products that are unqualified after pre-pressing but have the option of re-pre-pressing are pre-pressed again without affecting the structure of the main assembly process.

[0051] A pressure sensor assembly is provided between the first fixing block 1321 and the second housing clamping mechanism 1322. This allows for real-time monitoring and control of pressure changes during pre-compression, ensuring stable pre-compression quality.

Above the loading fixture 1002, the second vertical drive mechanism 1420 drives the flipping clamping mechanism 1440 and the second pre-compression mechanism 1450 to move down to the preset clamping position of the fourth contouring clamping finger 1441 on the flipping clamping mechanism 1440 (at this time, the third vertical drive mechanism 1451 drives the second pre-compression rod 1453 to be positioned above the corresponding loading fixture 1002). The flipping clamping mechanism 1440 drives the fourth contouring clamping finger 1441 to clamp the assembled pre-compression product and flip it 180 degrees. Then, the third vertical drive mechanism 1451 drives the second pre-compression rod 1453 to press down and pre-compress the assembled pre-compression product again. The assembled product is flipped and pre-compressed at the other end as well to ensure the quality of the pre-compression and prepare for subsequent welding.

[0053] Based on the above, such as Figure 1 , Figure 12 Zhihe Figure 14As shown, the welding mechanism 1500 includes a welding assembly 1510 for welding pre-pressed assembled products, a welding rotation module 1520 for transferring and positioning the products and driving them to rotate in coordination with the welding assembly 1510 to complete the welding, and an auxiliary rotation module 1530 that assists in lifting the pre-pressed assembled products from the corresponding loading fixture 1002 during the transfer process by the welding rotation module 1520 and supports the lower end of the products as they rotate during the rotation driven by the welding rotation module 1520. The welding assembly 1510 includes a seventh horizontal drive mechanism 1500 disposed on one side of the turntable mechanism 1001. 11. An eighth horizontal drive mechanism 1512, driven by a seventh horizontal drive mechanism 1511, moves horizontally relative to the corresponding loading device 1002 on the turntable mechanism 1001; a fourth vertical drive mechanism 1513, driven by the eighth horizontal drive mechanism 1512, moves horizontally along the direction perpendicular to the eighth horizontal drive mechanism 1512; a first rotary drive mechanism 1514, driven by the fourth vertical drive mechanism 1513, moves vertically; and a laser welding machine 1515, whose angle is adjusted by rotating vertically using the first rotary drive mechanism 1514.

The product clamping mechanism 1524 is provided with a shielding and fixing frame plate 1527. The shielding and fixing frame plate 1527 is provided with a plurality of vertically penetrating third limiting holes. A limiting rod 1528 is provided in the third limiting hole to limit vertical movement. The lower end of the limiting rod 1528 is fixed to the shielding and fixing frame plate 1527. The upper end of the limiting rod 1528 passes through the third limiting hole and is provided with a limiting boss with a diameter larger than the third limiting hole. A support spring 1529 is sleeved on the limiting rod 1528, located between the shielding plate 1526 and the shielding and fixing frame plate 1527 and in a compressed state.The auxiliary rotation module 1530 includes a sixth vertical drive mechanism 1531 located below the turntable mechanism 1001 and the corresponding loading unit 1002; a second vertical moving plate 1532 driven by the sixth vertical drive mechanism 1531 to move vertically relative to the corresponding loading unit 1002; a first pressure sensor 1533 mounted on the second vertical moving plate 1532; a bearing fixing plate assembly 1534 fixedly mounted on the first pressure sensor 1533; a bearing assembly 1535 mounted on the bearing fixing plate assembly 1534; and a welding lifting rod 1536 freely rotatable mounted on the bearing assembly 1535.

[0054] In practice, the welding rotation module 1520 and the auxiliary rotation module 1530 work together to automatically complete the 360-degree welding of the product's annular surface and move it back into the corresponding assembly loading fixture 1002 after welding for subsequent process operations.

This prevents oxidation during welding, increases weldability, and improves welding quality. The rotating module support 1521 is also equipped with a fume extraction pipe 1550 for fume extraction during welding. This maintains the welding environment and protects the health of welding personnel.

[0060] In this specific embodiment, the loading fixture 1002 is provided with two placement slots for loading the welded products. During implementation, the detection lifting mechanism 1630 automatically and simultaneously lifts the two products within the corresponding loading fixture 1002 upwards. The positioning clamping mechanism 1610 automatically positions the two lifted products simultaneously. The spring detection component 1620 automatically performs spring force detection on the two products positioned by the positioning clamping mechanism 1610. After the detection is completed, the spring detection component 1620 resets, the positioning clamping mechanism 1610 resets and releases the two lifted products, and the detection lifting mechanism 1630 resets and moves downwards. The two detected products fall into the corresponding loading fixture 1002 and are automatically transferred to the next process under the drive of the turntable mechanism 1001.
