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 and testing spring 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 an automatic assembly and testing spring mechanism for 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: an automatic assembly and testing spring mechanism on an ESC sensor assembly and welding equipment, including a turntable mechanism and multiple group loading units disposed on the turntable mechanism and driven and positioned by the turntable mechanism. Each group loading unit is provided with at least one cavity for placing the housing. The device also includes a spring assembly mechanism disposed around the turntable mechanism to automatically assemble springs into the housings of the corresponding group loading units, and a spring force testing mechanism to automatically test the spring force of the springs inside the welded sensor product. This fully automates the spring assembly and testing of the sensor product, achieving high speed, high efficiency, and stable quality.

[0005] Furthermore, the spring assembly mechanism includes at least one spring feeding mechanism for feeding springs and at least one spring implantation positioning module for aligning and implanting springs. The spring feeding mechanism includes a spring vibrating feeding disc for feeding springs, a spring blowing mechanism for blowing out springs fed by the spring vibrating feeding disc, a spring blowing pipe connected to the spring blowing mechanism for driving the spring implantation positioning module, and a spring discharge head connected to the end of the spring blowing pipe. The spring discharge head is fixedly mounted on the spring implantation positioning module and driven by the spring implantation positioning module to move relative to the corresponding assembly loading device. This facilitates the spring being implanted into the housing within the corresponding assembly loading device.

[0006] Furthermore, the spring implantation positioning module includes a first fixed bracket assembly located on one side of the turntable mechanism, a third horizontal drive mechanism mounted on the first fixed bracket assembly, a fourth horizontal drive mechanism mounted on the third horizontal drive mechanism and driven by the third horizontal drive mechanism to move horizontally relative to the corresponding loading unit on the turntable mechanism, a first vertical drive mechanism mounted on the fourth horizontal drive mechanism and driven by the fourth horizontal drive mechanism to move along a direction perpendicular to the fourth horizontal drive mechanism, a first vertical fixing plate mounted on the first vertical drive mechanism and driven by the first vertical drive mechanism to move vertically, an industrial camera for positioning and observation mounted on the first vertical fixing plate, and an outlet head fixing block for fixing the spring outlet head. This allows for high-precision and rapid positioning and movement of the spring outlet head to a preset implantation position within the housing of the corresponding loading unit.

[0007] Furthermore, the elasticity testing mechanism includes a lifting mechanism for detecting welded products within the corresponding loading fixture on the lifting turntable mechanism, a positioning clamping mechanism for holding the products lifted by the lifting mechanism, and a spring detection assembly for detecting each spring on the products held by the positioning clamping mechanism. This automates the spring detection of the welded products, resulting in high efficiency and stable detection quality.

[0008] Furthermore, the detection lifting mechanism comprises two sets, each including a seventh vertical drive mechanism located below the turntable mechanism and the corresponding loading unit, and a detection lifting rod driven by the seventh vertical drive mechanism to move vertically relative to the corresponding loading unit. The turntable mechanism and the corresponding loading unit have detection lifting holes on the product placement slots corresponding to the detection lifting rods, allowing the detection lifting rods to move vertically. The structure is simple, highly applicable, and automates product lifting.

[0009] Furthermore, the positioning and clamping mechanism includes a ninth horizontal drive mechanism corresponding to the corresponding loading unit and a first detection and clamping mechanism driven by the ninth horizontal drive mechanism to move horizontally relative to the product within the corresponding loading unit. The first detection and clamping mechanism is equipped with a fifth contoured clamping finger that is driven to clamp the outer surface of the product within the corresponding loading unit. The structure is simple, highly applicable, and automates clamping and positioning.

[0010] Furthermore, the spring detection assembly includes a tenth horizontal drive mechanism located on one side of the turntable mechanism, an eleventh horizontal drive mechanism driven by the tenth horizontal drive mechanism to move relative to the corresponding assembly loading device, two eighth vertical drive mechanisms driven by the eleventh horizontal drive mechanism to move horizontally along the direction perpendicular to the eleventh horizontal drive mechanism, an elastic detection fixing plate driven by the eighth vertical drive mechanism to move vertically, a second pressure sensor located on the elastic detection fixing plate, and a spring force detection rod fixed on the second pressure sensor for elastically contacting the spring on the product positioned by the positioning clamping mechanism. This allows for automated detection of the springs on the assembly loading device product, offering high speed, high efficiency, and wide applicability. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 The automatic assembly and testing spring mechanism on an ESC sensor 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 the housing. The equipment also includes a spring assembly mechanism 1200 disposed around the turntable mechanism 1001 to automatically assemble springs into the housings of the corresponding assembly loading units 1002, and an elasticity testing mechanism 1600 to automatically test the elasticity of the springs inside the welded sensor products. In this specific embodiment, the turntable mechanism (1001) is a commercially available double-layer turntable comprising a fixed upper disc and a rotating lower disc. The turntable mechanism 1001 transports the loading unit 1002 to the corresponding position of the spring assembly mechanism 1200, where the spring assembly mechanism 1200 automatically assembles the springs within the upper housing of the loading unit 1002. After the welding process is completed, the products within the loading unit 1002 are transferred by the turntable mechanism 1001 to the corresponding position of the elasticity testing mechanism 1600, where the elasticity testing mechanism 1600 automatically performs elasticity testing on the springs within the welded sensor products. This fully automated process completes the spring assembly and testing of the sensor products, resulting in high speed, high efficiency, and stable quality.

[0021] Based on the above, such as Figure 1 and Figure 2 As 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 vibration feeding plate 1211 for feeding springs, a spring blowing mechanism for blowing out springs fed by the spring vibration feeding plate 1211, a spring blowing pipe connected to the spring blowing mechanism for driving the spring blowing mechanism, 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. In this specific embodiment, the spring vibration feeding plate 1211 is a commercially available spring vibration feeding plate of suitable model. The spring blowing mechanism is an external air supply pump mechanism with the air outlet fixed on the spring vibration feeding plate. The spring blowing pipe is a transparent spring guide feeding pipe, which is convenient for observing the feeding situation during use. The spring discharge head 1212 is a straight guide tube fixed on the spring implantation positioning module 1220, which is convenient for the spring to be implanted into the housing inside the corresponding loading device 1002 after discharge.

[0022] Based on the above, such as Figures 1 to 3 As shown, the spring implantation positioning module 1220 includes a first fixed bracket assembly 1221 located on one side of the turntable mechanism 1001, a third horizontal drive mechanism 1222 disposed on the first fixed bracket assembly 1221, a fourth horizontal drive mechanism 1223 disposed on the third horizontal drive mechanism 1222 and driven by the third horizontal drive mechanism 1222 to move horizontally relative to the corresponding loading device 1002 on the turntable mechanism 1001, a first vertical drive mechanism 1224 disposed 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 fixing plate 125 disposed 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 disposed on the first vertical fixing plate 125, and a discharge head fixing block 1226 for fixing the spring discharge head 1212. 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 cylinder assemblies with controllable stroke. This allows for 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 device 1002.

[0023] Based on the above, such as Figure 1 and Figure 4 As shown, the elasticity testing mechanism 1600 includes a detection lifting mechanism 1630 for detecting welded products in the corresponding loading fixture 1002 on the lifting turntable mechanism 1001, a positioning clamping mechanism 1610 for clamping the products lifted by the detection lifting mechanism 1630, and a spring detection assembly 1620 for detecting each spring on the products clamped by the positioning clamping mechanism 1610. 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. This automated spring detection of the welded products is highly efficient and provides stable detection quality.

[0024] Based on the above, such as Figure 1 , Figure 4 and Figure 5 As shown, the detection lifting mechanism 1630 has two sets, each including a seventh vertical drive mechanism 1631 located below the turntable mechanism 1001 and the corresponding loading fixture 1002, and a detection lifting rod 1632 driven by the seventh vertical drive mechanism 1631 to move vertically relative to the corresponding loading fixture 1002. The turntable mechanism 1001 and the corresponding loading fixture 1002 have detection lifting holes on the product placement slots corresponding to the detection lifting rod 1632, allowing the detection lifting rod 1632 to move up and down. In this specific embodiment, the seventh vertical drive mechanism 1631 is a vertically arranged slide cylinder assembly. In specific implementations, the seventh vertical drive mechanism 1631 can also be a linear drive mechanism such as a linear motor; it has a simple structure, strong applicability, and automates product lifting.

[0025] Based on the above, such as Figure 1 , Figure 4 and Figure 6 As shown, the positioning and clamping mechanism 1610 includes a ninth horizontal drive mechanism 1611 corresponding to the corresponding loading unit 1002 and a first detection and clamping mechanism 1612 driven by the ninth horizontal drive mechanism 1611 to move horizontally relative to the product in the corresponding loading unit 1002. The first detection and clamping mechanism 1612 is provided with a fifth contoured clamping finger 1613 driven by it to clamp the outer surface of the product in the corresponding loading unit 1002. In this specific embodiment, the ninth horizontal drive mechanism is a horizontally arranged slide cylinder assembly. In specific implementations, the ninth horizontal drive mechanism can also be a linear drive mechanism such as a linear motor. The first detection and clamping mechanism 1612 has two clamping claw cylinders, each corresponding to two products in the loading unit 1002. The structure is simple, the applicability is strong, and the clamping and positioning are completed automatically.

[0026] Based on the above, such as Figure 1 , Figure 4 and Figure 7As shown, the spring detection assembly 1620 includes a tenth horizontal drive mechanism 1621 disposed on one side of the turntable mechanism 1001, an eleventh horizontal drive mechanism 1622 driven by the tenth horizontal drive mechanism 1621 to move relative to the corresponding loading device 1002, two eighth vertical drive mechanisms 1623 driven by the eleventh horizontal drive mechanism 1622 to move horizontally along the direction perpendicular to the eleventh horizontal drive mechanism 1622, an elastic detection fixing plate 1624 driven by the eighth vertical drive mechanism 1623 to move vertically, a second pressure sensor 1625 disposed on the elastic detection fixing plate 1624, and an elastic force detection rod 1626 fixed on the second pressure sensor 1625 for elastically contacting the spring on the product positioned by the positioning clamping mechanism 1610. In this specific embodiment, the tenth horizontal drive mechanism 1621, the eleventh horizontal drive mechanism 1622, and the eighth vertical drive mechanism 1623 are all linear drive mechanisms composed of servo motors and ball screw slide modules. In specific implementations, the tenth horizontal drive mechanism 1621, the eleventh horizontal drive mechanism 1622, and the eighth vertical drive mechanism 1623 can also be linear motor assemblies or cylinder assemblies with controllable stroke. At the same time, the springs on the two products in the assembly loading device 1002 are automatically detected, which is fast, efficient, and highly applicable.

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.
