Description

Technical Field

[0001] This utility model relates to the field of engine processing equipment technology, specifically to an automatic assembly device for automotive engine coolant temperature sensors. Background Technology

[0002] Currently, with the rapid development of domestic automobiles and the rapid growth of domestic automobile production, manufacturers are increasingly demanding higher production efficiency. Under normal circumstances, the coolant temperature sensor on the engine still uses a semi-automatic manual assembly process, requiring manual pre-installation followed by installation with a tightening gun. This manual operation inevitably carries the risk of omissions, resulting in higher costs and generally lower efficiency. Furthermore, the current assembly process typically uses a vibratory feeder to sort and feed the coolant temperature sensors, leading to collisions and wear between materials. For some vulnerable parts, this process can easily damage components. Utility Model Content

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0031] like Figure 1 As shown, this embodiment provides an automatic assembly device for an automotive engine coolant temperature sensor, including a workbench 1 and a conveyor 2. A code disk 3 carrying a coolant temperature sensor 11 is placed on the workbench 1. A vision inspection component 4 for positioning the coolant temperature sensor 11 is provided at the upper end of the workbench 1. A robotic arm 5 is provided on one side of the upper end of the workbench 1. A clamping and tightening mechanism for assembling the coolant temperature sensor 11 is installed at the end of the robotic arm 5. The clamping and tightening mechanism includes a bracket 51, a clamping component installed on one side of the bracket 51, and a tightening component installed on the other side of the bracket 51, to respectively realize the clamping, conveying, and tightening actions of the coolant temperature sensor 11. The conveyor 2 is installed on one side of the workbench 1. The conveyor 2 is used to sequentially guide the cylinder head 21 of the engine. The conveyor 2 is provided with a stop component to stop the cylinder head 21, and a pressing mechanism for positioning the cylinder head 21 is also installed at a corresponding position on the conveyor 2 to ensure the stability of the cylinder head 21 during assembly.

[0032] like Figure 2 As shown, in this embodiment, due to the poor workmanship of the encoder 3 for placing the water temperature sensor 11, the placement of the water temperature sensor 11 cannot be guaranteed, which will lead to the water temperature sensor 11 not being installed properly. Therefore, it is necessary to perform secondary positioning of the water temperature sensor 11 to improve the assembly accuracy of the water temperature sensor 11. To solve the above problem, this embodiment provides a technical solution:

[0033] The workbench 1 is also provided with a positioning component for secondary positioning of the water temperature sensor 11 on one side. The positioning component includes a positioning plate 12 and a centering component disposed on the outside of the positioning plate 12. The positioning plate 12 is provided with a plurality of contour holes corresponding to the water temperature sensor 11. The centering component is installed on the outside of one of the contour holes. The centering component includes a centering gripper cylinder 13 and a centering plate 14 disposed on the grippers on both sides of the centering gripper cylinder 13.

[0034] Specifically, the robotic arm 5 uses a gripping assembly to move the water temperature sensor 11 on the encoder 3 to the upper end of the positioning plate 12. The gripping assembly releases the water temperature sensor 11, allowing it to fall into the contour hole under gravity. The centering gripper cylinder 13 controls the centering plate 14 to close, thus positioning the water temperature sensor 11 within the contour hole. This ensures good repeatability of the water temperature sensor 11. The tightening assembly then grips the corresponding water temperature sensor 11, the centering gripper cylinder 13 releases, and the tightening assembly removes the water temperature sensor 11 for installation. The contour holes distributed on the outer end of the positioning plate 12 can be used to place the water temperature sensor 11, ensuring continuous processing without interruption of material handling when personnel change the encoder 3.

[0035] like Figure 3 As shown, in this embodiment, the workbench 1 is provided with a mold base 31 for placing the code disk 3, and clamping members for clamping and fixing the code disk 3 are provided on both sides of the mold base 31. The clamping members include clamping cylinders 32 installed on both sides of the mold base 31. A clamping plate 33 is fixedly installed on the outer end of the output rod of the clamping cylinder 32.

[0036] like Figure 1 As shown, in this embodiment, the vision inspection component 4 is installed on the frame 15 at the outer end of the workbench 1. The vision inspection component 4 includes a servo module 43 installed on the frame 15 and an inspection frame 41 set on the servo module 43. A vision camera 42 is fixedly installed at the lower middle part of the inspection frame 41 to perform visual positioning of the water temperature sensor 11 placed on the workbench 1. Two sets of code disks 3 are placed on the workbench 1. The servo module 43 controls the movement of the inspection frame 41 to drive the vision camera 42 to switch positions, thereby detecting and positioning the corresponding code disks 3.

[0037] like Figure 4As shown, in this embodiment, the clamping assembly includes a lifting cylinder 52 mounted on the bracket 51 and a guide gripper cylinder 53 disposed at the lower end of the lifting cylinder 52. The guide gripper cylinder 53 is fixedly mounted at the lower end of the output rod of the lifting cylinder 52, and clamping plates 54 are fixedly mounted on the clamping arms on both sides of the guide gripper cylinder 53 so as to close and grasp the water temperature sensor 11 through the clamping plates 54. The robotic arm 5 uses the clamping assembly to transport the water temperature sensor 11 on the encoder 3 to the positioning plate 12.

[0038] like Figure 4 and Figure 5 As shown, in this embodiment, the tightening assembly includes a bearing seat 55 slidably mounted on one side of the bracket 51 and a vacuum sleeve 56 rotatably mounted inside the bearing seat 55. The upper end of the bracket 51 is provided with a straight handle gun 57 that drives the vacuum sleeve 56 to rotate, and the straight handle gun 57 is fixedly mounted on the bracket 51. One side of the bearing seat 55 is slidably mounted on the corresponding slide rail of the bracket 51 via a slider, and a sealing cavity 58 is provided inside the bearing seat 55. An air pipe connector communicating with the sealing cavity 58 is provided outside the bearing seat 55, and an external air extraction device is connected through the air pipe connector. The upper end of the vacuum sleeve 56 is provided with an air hole communicating with the sealing cavity 58, so that the vacuum sleeve 56 generates negative pressure. The suction cylinder 59 at the lower end of the vacuum sleeve 56 is used to grasp and fix the water temperature sensor 11. The suction cylinder 59 is provided with a positioning groove for positioning the water temperature sensor 11 to ensure the accuracy of the grasping position of the water temperature sensor 11.

[0039] like Figure 6 As shown, in this embodiment, the stop assembly includes stop cylinders 22 symmetrically installed on both sides of the conveyor 2. A stop plate 23 is fixedly installed on the outer end of the output rod of the stop cylinder 22 to abut against one side of the cylinder head 21. A sensor for detecting the position of the cylinder head 21 is provided on the stop plate 23.

[0040] The pressing mechanism includes a top plate 24 installed on the upper end of the conveyor 2 and a lifting assembly installed on the lower end of the conveyor 2. The lifting assembly includes a lifting frame 25 and a bottom plate 27 that can be lifted and lowered within the lifting frame 25. The lower end of the lifting frame 25 is provided with a lifting cylinder 26 that pushes the bottom plate 27 to move up and down. Linear bearings that are slidably installed on the lifting frame 25 are also provided on both sides of the lower end of the bottom plate 27 to improve the stability of the bottom plate 27 during the lifting process. Support plates 28 are distributed at intervals on the upper end of the bottom plate 27. Positioning pins 29 are distributed on the upper end of the support plates 28 corresponding to the holes on the cylinder cover 21. The top plate 24 is installed at the corresponding position on the upper end of the conveyor 2 via a top frame and is set in conjunction with the lifting assembly.

[0041] Specifically, the stop assembly blocks the conveying cylinder head 21, the lifting cylinder 26 controls the support plate 28 to rise, the support plate 28 extends from between the guide rollers spaced apart on the conveyor 2, and inserts the positioning pin 29 into the corresponding positioning hole of the cylinder head 21, and drives the cylinder head 21 to rise, the upper end of the cylinder head 21 abuts against the top plate 24, thereby clamping and fixing the cylinder head 21, which facilitates the subsequent installation of the water temperature sensor 11.

[0042] The working principle of this utility model is as follows: A controller is provided at the lower end of the workbench 1. The controller is electrically connected to the robotic arm 5, the clamping mechanism, the vision inspection component 4, the conveyor 2, the stop component and the pressing mechanism in sequence to realize the orderly operation of the equipment. Several sets of sensors are also distributed on the equipment for detection and positioning.

[0043] Specifically, the cylinder head 21 is sequentially guided to the corresponding position by the conveyor 2 and positioned by the stop assembly. The lifting cylinder 26 controls the support plate 28 to rise, and the positioning pin 29 is inserted into the corresponding positioning hole of the cylinder head 21, pushing the cylinder head 21 to rise and abut against the top plate 24, thereby fixing the cylinder head 21. After processing, the support plate 28 is lowered, so that the cylinder head 21 is guided forward on the conveyor 2.

[0044] Personnel place the code disk 3 on the mold base 31. The clamping cylinder 32 controls the clamping plate 33 to fix the code disk 3. The robotic arm 5 grabs the water temperature sensor 11 through the clamping component and moves the water temperature sensor 11 to the positioning plate 12. The robotic arm 5 switches the tightening component to adsorb and grab the water temperature sensor 11. The robotic arm 5 moves to insert the water temperature sensor 11 into the corresponding position hole of the cylinder head 21. The straight handle gun 57 controls the vacuum sleeve 56 to rotate so as to automatically install the water temperature sensor 11 on the cylinder head 21.

[0045] This device transforms the original manual tightening process of installing the water temperature sensor 11 into a fully automated mechanized installation, improving the assembly efficiency and installation qualification rate of the engine water temperature sensor 11, reducing unnecessary manual labor, and requiring only periodic replenishment of the water temperature sensor 11 in the encoder 3, ensuring continuous production on the production line. The robotic arm 5 uses a clamping assembly to clamp and move the water temperature sensor 11 from the encoder 3 to the positioning plate 12, achieving secondary positioning of the water temperature sensor 11 and ensuring good repeatability of the water temperature sensor 11.
