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 a semi-finished product assembly mechanism on an ESC sensor assembly and welding equipment. 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

[0003] This invention provides a semi-finished product assembly mechanism on an ESC sensor assembly and welding equipment, which solves the technical problems of excessive manual operation, low efficiency, and poor quality stability in the existing automatic assembly, conditioning, testing and production process of ESC sensors.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a semi-finished product assembly mechanism on an ESC sensor assembly and welding equipment, including a turntable mechanism and multiple group loading devices disposed on the turntable mechanism and driven and positioned by the turntable mechanism. Each group loading device is provided with at least one cavity for placing the housing and at least one cavity for placing the sensor semi-finished product. A semi-finished product assembly mechanism is provided on one side of the turntable mechanism for automatically assembling the sensor semi-finished product within a housing equipped with springs. The assembly of the housing and sensor semi-finished product is fully automated, with high speed, high efficiency, and stable quality.

[0005] Furthermore, the semi-finished product assembly mechanism includes an assembly positioning mechanism, a pre-compression assembly mechanism, a defective product temporary storage mechanism, and an assembly inspection mechanism. The assembly positioning mechanism is located on one side of the turntable mechanism, opposite to the corresponding loading fixture on the turntable mechanism that requires semi-finished product assembly. The pre-compression assembly mechanism is used for assembling, pre-compressing, and transferring the pre-compressed products. The assembly inspection mechanism is located within the product transfer range of the pre-compression assembly mechanism and performs visual inspection on the products transferred by the pre-compression assembly mechanism. The defective product temporary storage mechanism is located within the product transfer range of the pre-compression assembly mechanism and is used to temporarily store defective products after assembly. This automated process completes the assembly, pre-compression, and preliminary inspection of the sensor semi-finished products and the spring-loaded housing, resulting in high efficiency and strong stability.

[0006] Furthermore, the assembly positioning mechanism includes a fifth horizontal drive mechanism and at least one first housing clamping mechanism driven by the fifth horizontal drive mechanism to move horizontally relative to the inner housing of the corresponding assembly loading device. The first housing clamping mechanism is provided with a second contoured clamping finger driven by it to clamp the middle of the outer surface of the housing. The structure is simple, the operation is stable, and there is minimal mutual interference.

[0007] Furthermore, the pre-compression assembly mechanism includes a multi-axis robotic arm, a first fixed block, a second housing clamping mechanism, a positioning and observation mechanism, and a first pre-compression structure. The first fixed block is fixedly mounted on the multi-axis robotic arm and driven by the multi-axis robotic arm to move horizontally and vertically, and rotate horizontally. The second housing clamping mechanism and the positioning and observation mechanism are both fixedly mounted on the first fixed block. The second housing clamping mechanism is equipped with a third contoured gripper finger 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 is mounted on the second housing clamping mechanism and one end extends to the upper side of the clamping position of the third contoured gripper finger, which can apply elastic pressure to the upper end of the product. Automated elastic pre-compression effectively reduces damage to the product during pre-compression.

[0008] Furthermore, the first pre-compression structure includes a first pre-compression fixing block, a second pre-compression fixing block, a first pre-compression rod, and a first pre-compression spring. The first pre-compression fixing block is fixed to the second housing clamping mechanism. The second pre-compression fixing block is fixed to the lower end of the first pre-compression fixing block, with one end extending to the upper side of the third contour finger clamping position. A first vertically penetrating limiting hole is provided at the corresponding positions of the second pre-compression fixing block and the third contour finger clamping position. The first pre-compression rod 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 pre-compression rod. The first pre-compression spring is sleeved on the outer surface of the first pre-compression rod and located between the limiting cap at the lower end of the first pre-compression rod and the lower surface of the second pre-compression fixing block. This simple structure achieves pre-compression of the assembled product.

[0009] Furthermore, the defective product temporary storage mechanism includes a rectangular temporary storage tray and a temporary storage fixing bracket. The rectangular temporary storage tray is evenly provided with multiple defective storage slots for temporarily storing defective products after the housing and sensor semi-finished products have been assembled and pre-compressed. The upper end of the temporary storage fixing bracket is provided with a temporary storage limiting plate. Multiple right-angle limiting blocks are provided around the periphery of the temporary storage limiting plate to limit the outer corners of the rectangular temporary storage tray. Alternating notches are provided on the temporary storage limiting plate and at positions corresponding to the defective storage slots on the rectangular temporary storage tray. The rectangular temporary storage tray is easy to place and remove, allowing for the batch removal of defective products and the replacement of empty rectangular temporary storage trays.

[0010] Furthermore, a pre-compression storage block is provided on the outer edge of one end of the temporary storage limiting plate. This pre-compression storage block has multiple transition storage slots for the pre-compressed product after assembling the housing and sensor semi-finished products. These transition storage slots extend vertically and have photoelectric sensors at their bottom for detecting whether the product is placed inside. When the pre-compressed product is placed into a transition storage slot, its middle portion is inside the slot and its upper portion is above it. The transition storage slot is higher than the right-angle limiting block. The width of the pre-compression storage block is less than the maximum distance between the clamping fingers after the second housing clamping mechanism drives the third contouring clamping fingers to separate. Products that fail the pre-compression process but have the option for further pre-compression are pre-compressed again without affecting the structure of the main assembly process.

[0011] Furthermore, a pressure sensor assembly is installed between the first fixing block and the second housing clamping mechanism. This allows for real-time monitoring and control of pressure changes during pre-compression, ensuring stable pre-compression quality. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 The diagram illustrates a semi-finished product assembly mechanism on an ESC sensor assembly and welding equipment. It includes a turntable mechanism and multiple assembly carriers 1002 mounted on the turntable mechanism and driven for transfer and positioning by the turntable mechanism. Each assembly carrier 1002 has at least one acupoint for placing a housing and at least one acupoint for placing a sensor semi-finished product. A semi-finished product assembly mechanism is located on one side of the turntable mechanism, which automatically assembles the sensor semi-finished product within a housing equipped with springs. In this specific embodiment, the turntable mechanism is a commercially available double-layer turntable comprising a fixed upper disc and a rotating lower disc. In practice, the turntable mechanism carries the assembly carriers 1002 to transfer the sensor semi-finished product and the housing equipped with springs to the corresponding positions of the semi-finished product assembly mechanism, which then automatically assembles the sensor semi-finished product within the housing equipped with springs. This fully automated assembly of the housing and sensor semi-finished product is fast, efficient, and of stable quality.

[0020] Based on the above, such as Figure 1As shown, the semi-finished product assembly mechanism 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 and is opposite to the corresponding loading device 1002 on the turntable mechanism 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. 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 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. 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.

[0021] Based on the above, such as Figure 1 and Figure 2As shown, 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, making room while ensuring effective positioning and fixing, 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.

[0022] Based on the above, such as Figures 1 to 3As shown, 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.

[0023] Based on the above, such as Figure 1 and Figure 4As shown, 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 1324 are connected. A vertically penetrating first limiting hole is provided at the clamping position of the finger 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.

[0024] Based on the above, such as Figure 1 and Figure 5 As shown, 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 and the defective temporary storage slots 1333 on the rectangular temporary storage tray 1331 are provided with clearance notches. 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.

[0025] Based on the above, such as Figure 1 and Figure 5As shown, 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 a photoelectric sensor 1362 is provided 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 practice, 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. After pre-pressing, it is transferred 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 or to 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.

[0026] Based on the above, such as Figure 1 and Figure 3 As shown, 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.

[0027] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
