Description

Technical Field

[0001] This invention relates to the field of pressure sensor technology, specifically to an assembly device and method for an automotive brake pressure sensor. Background Technology

[0002] The most critical assembly operation of an automotive brake pressure sensor is connecting and fixing four independent components: the base containing the circuit board, the elastic element, the frame with the sleeve attached, and the fixing bracket. The assembly process is as follows: first, the elastic element is installed on the frame; then, the fixing bracket is snapped on to secure the elastic element; finally, the sleeve is fitted onto the base to complete the assembly.

[0003] The above assembly methods mainly include the following two: One method is purely manual assembly, where operators rely entirely on manual labor to handle all parts handling, alignment, pressing, and testing. While this method offers advantages such as low initial equipment investment and high flexibility, it is inefficient and incurs high labor costs.

[0004] Secondly, there is fully automated assembly, which introduces highly integrated fully automated assembly lines. This model achieves automated operation through robotic arms, precision guide rails, and vision systems, and can ideally achieve high-cycle production. However, the initial development and manufacturing costs are extremely high. The design, research and development, manufacturing, and debugging cycle of non-standard automated equipment is long, requiring huge capital investment, making it uneconomical for many small and medium-sized enterprises or projects with rapid product iteration. Moreover, the equipment integrates multiple systems such as mechanical, electrical, pneumatic, and software, requiring highly skilled maintenance personnel, making troubleshooting difficult, and incurring considerable costs for daily maintenance and spare parts replacement.

[0005] Therefore, how to overcome the above-mentioned defects has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] To address the technical problems in the background art, this invention discloses an assembly device and assembly method for an automotive brake pressure sensor.

[0007] This invention provides an assembly device for an automotive brake pressure sensor, used to assemble a base, an elastic element, a frame, and a fixing bracket. One end of the frame is fitted with a sleeve. The device includes: The first tooling plate is used to clamp and fix multiple evenly spaced skeletons, with the skeletons located at the lower end and the sleeves located at the upper end. The second tooling plate can be positioned above the first tooling plate; the second tooling plate has guide and correction holes, and the elastic element falls vertically into the mounting hole on the frame under the guidance and correction of the guide and correction holes; the second tooling plate is removed after the elastic element is installed. The third tooling plate is used to snap and fix the fixing bracket; The first pressing component is equipped with a support plate; the third tooling plate can be limited and installed on the support plate so that the first adsorption block on the first pressing component can accurately adsorb the fixing frame; when the first tooling plate is limited and installed on the support plate, the first adsorption block moves down, presses the fixing frame into the sleeve and engages with the skeleton; after the engagement is completed, the first adsorption block releases the fixing frame and resets. The fourth tooling plate is used to snap the fixing frame and the skeleton together. The sleeve is located on the lower side and snaps onto the fourth tooling plate, while the skeleton is located on the upper side. The second pressing component has the same structure as the first pressing component, and is provided with a second adsorption block that replaces the first adsorption block; When the fourth tooling plate is positioned on the tray of the second pressing component, the second adsorption block adsorbs the skeleton and drives the fixed frame and the skeleton to move upward together after they are engaged. The fifth tooling plate is used to limit the mounting base; When the fifth tooling plate is positioned on the support plate of the second pressing component, the second adsorption block moves down, pressing the lower end of the sleeve into and fixing it to the base.

[0008] Furthermore, the third tooling plate is always fixedly mounted on the support plate of the first pressing assembly.

[0009] Furthermore, the fourth tooling plate is always positioned and mounted on the support plate of the second pressing assembly.

[0010] Furthermore, the first pressing assembly and the second pressing assembly also include a pressure plate that is driven to rise and fall by a cylinder, and the first adsorption block and the second adsorption block are installed at the lower end of the pressure plate; The first and second adsorption blocks are elastically connected to the pressure plate by springs, so that the first and second adsorption blocks have a buffer space for vertical floating.

[0011] Furthermore, handles are symmetrically arranged on both sides of the pressure plate; Before the piston rod of the cylinder extends downward and applies downward pressure to the pressure plate, the handle is first manually held to drive the pressure plate downward, so that the first adsorption block adsorbs the fixing frame, or the second adsorption block adsorbs the skeleton.

[0012] Furthermore, the first pressing assembly and the second pressing assembly also include a support; a pulley is provided on the top of the support; a wire rope is wound around the pulley, one end of which is fixedly connected to the pressure plate and the other end is fixedly connected to the counterweight. When the operator releases the handle, the counterweight is pulled up and reset by the steel wire rope to pull the pressure plate.

[0013] The present invention also provides an assembly method for an automotive brake pressure sensor assembly device, comprising the following steps: S1. Position the skeleton in the positioning hole of the first tooling plate, with the skeleton at the lower end and the sleeve at the upper end. S2. Position the second tooling plate above the first tooling plate; S3. Insert the elastic element into the guide correction hole of the second tooling plate, so that the elastic element slides into the mounting hole of the skeleton along the guide correction hole. S4. Remove the second tooling plate; S5. Position the fixing bracket in the positioning hole of the third tooling plate; S6. Manually drive the pressure plate on the first pressing assembly to move down, so that the first adsorption block adsorbs the fixing frame and drives the fixing frame to move up and detach from the third tooling plate. S7. Position the first tooling plate, which is equipped with the skeleton and elastic element, at the upper end of the third tooling plate; S8. Start the cylinder on the first pressing assembly. The piston rod moves down and pushes the pressure plate on the first pressing assembly to move down. At the same time, it applies downward pressure to the fixed frame, pressing the fixed frame into the sleeve, so that the locking teeth at the lower end of the fixed frame are engaged and fixed with the skeleton. S9. The cylinder on the first pressing component drives the pressure plate to rise and reset. S10. Move the entire assembly of the skeleton, elastic element and fixing frame into the positioning hole of the fourth tooling plate, with the skeleton at the upper end and the sleeve at the lower end. S11. Manually drive the pressure plate on the second pressing component to move down, so that the second adsorption block adsorbs the skeleton and drives the connecting whole to move up and detach from the fourth tooling plate. S12. The fifth tooling plate equipped with the base is positioned at the upper end of the fourth tooling plate. S13. Start the cylinder on the second pressing assembly. The piston rod moves down to apply pressure to the pressure plate on the second pressing assembly, pressing the lower end of the sleeve into and fixing it to the base, thus completing the assembly of the base, elastic element, skeleton and fixing frame.

[0014] The beneficial effects of this invention are: 1. Multiple specialized tooling plates are used to position and fix the frame, elastic elements, fixing bracket, sleeve, and base, respectively, and the pressing and snapping operations are completed in conjunction with the adsorption block of the pressing component. This invention replaces traditional manual assembly, reduces manual operation steps and alignment difficulties, improves assembly speed, and ensures the consistency of the assembly position of each component, reducing the product defect rate caused by human error. Compared with fully automated production lines, this device has a simplified structure and does not require complex robotic arms, vision systems, or multi-system integration. Through the limiting design of the tooling plates and the universal adsorption pressing function of the pressing component, semi-automated operation of key processes is achieved, significantly reducing the initial equipment R&D and manufacturing costs, debugging cycle, and subsequent maintenance costs. The modular tooling plates are easy to replace or adjust, making them more suitable for small and medium-sized enterprises or application scenarios with frequent product iterations.

[0015] 2. Each tooling plate can be used independently or combined on the pallet to adapt to the needs of different assembly stages. This modular design allows the equipment to flexibly adjust the process sequence or adapt to different product models, enhancing the adaptability and scalability of the production line.

[0016] 3. The device uses a tooling plate as a carrier. Operators only need to place the parts and replace the tooling plate. The force control links such as pressing are automatically completed by the pressing component, which reduces labor intensity and operational risks. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0020] This invention discloses an assembly device for an automotive brake pressure sensor, such as... Figure 15 and Figure 16 As shown, it is used to assemble four independent components: base 1, elastic element 2, frame 3 and fixing frame 4. One end of the frame 3 has been fixed with a sleeve 5 by means of a sleeve connection. It includes a first tooling plate 6, a second tooling plate 7, a third tooling plate 8, a fourth tooling plate 10, a fifth tooling plate 11, a first pressing component 9 and a second pressing component 12.

[0021] like Figure 1 As shown, the upper end face of the first tooling plate 6 is provided with a plurality of evenly spaced, blind-hole type first positioning holes 61. The shape of the first positioning holes 61 is similar to that of the skeleton 3, and is used to engage and limit the skeleton 3. The skeleton 3 is located on the lower side and the sleeve 5 is located on the upper side.

[0022] like Figure 2 and Figure 3As shown, the upper end of the second tooling plate 7 is provided with multiple sets of evenly spaced guide and correction holes, each set of which has four circumferentially evenly arranged guide and correction holes 71. When the second tooling plate 7 is placed on top of the first tooling plate 6, the guide and correction holes 71 are coaxial with the mounting holes 31 on the frame 3 for mounting the elastic element 2. The elastic element 2 is axially inserted into the guide and correction holes 71 and, under the guidance and correction of the guide and correction holes 71, is inserted vertically into the mounting holes 31. The bottom of the first positioning hole 61 is also provided with four circumferentially evenly distributed first positioning grooves 62. The lower end of the elastic element 2 abuts against the first positioning grooves 62 to achieve axial positioning. To ensure that the elastic element 2 can be accurately inserted into the guide and correction holes 71, the guide and correction holes 71 are also designed with a flared structure.

[0023] Because the guide correction hole 71 is directly machined on the second tooling plate 7, it would only be suitable for one type of pressure sensor, limiting its applicability. Therefore, a recessed clamping platform 72 is provided at the upper end of the second tooling plate 7. A clamping plate 73 with the guide correction hole 71 is clamped into the clamping platform 72 and secured with bolts. Thus, by simply replacing the clamping plate 73 with different guide correction holes 71, the second tooling plate 7 can be adapted to different types of pressure sensors.

[0024] To improve the coaxiality of the guide correction hole 71 and the mounting hole 31, a positioning post 63 is provided at the upper end of the first tooling plate 6, and a second positioning hole 74 is provided on the second tooling plate 7 to fit the positioning post 63.

[0025] like Figure 4 As shown, the second tooling plate 7 is removed after the elastic element 2 is installed. Compared to the operation of manually inserting the elastic element 2 through the sleeve 5 into the mounting hole 31, the second tooling plate 7 provides accurate guidance, which not only overcomes the problem of insufficient operating space, but also improves the accuracy of the position of the elastic element 2 inserted into the mounting hole 31.

[0026] like Figure 5 As shown, the upper surface of the third tooling plate 8 is provided with a third positioning groove 81, which is similar in shape to the fixing frame 4 and is used to engage the limiting fixing frame 4.

[0027] like Figure 6 As shown, the upper end of the fourth tooling plate 10 is provided with a fourth positioning hole 101, which is used to engage the sleeve 5, with the sleeve 5 located on the lower side and the skeleton 3 located on the upper side.

[0028] like Figure 7 As shown, the upper end of the fifth tooling plate 11 is provided with a fifth positioning hole 111, which is similar in shape to the base 1 and is used to engage and limit the base 1.

[0029] like Figure 9 and Figure 10 As shown, the first pressing assembly 9 and the second pressing assembly 12 have the same structure, the difference being that the first pressing assembly 9 is equipped with a first adsorption block 92 for adsorbing the fixing frame 4, while the second pressing assembly 12 is equipped with a second adsorption block 121 for adsorbing the skeleton 3; another difference is that the stroke of the cylinder 94 in the first pressing assembly 9 and the second pressing assembly 12 is different. Both the first pressing assembly 9 and the second pressing assembly 12 include a support 97, with a horizontally arranged support plate 91 at the lower end of the support 97 and a vertically arranged mounting plate 90 at the rear. Two vertically extending, spaced linear guides are provided on the front side of the mounting plate 90, and the lifting plate is fixedly connected to the slider of the linear guide. A horizontally arranged pressure plate 93 is provided on the lower end face of the lifting plate, and is fixed by bolts. Figure 12-14 As shown, multiple evenly spaced, vertically extending sliding sleeves 931 are inserted into the pressure plate 93 and are secured by bolts threaded to the pressure plate 93. A connecting shaft 934 is slidably inserted into each sliding sleeve 931. The lower end of the connecting shaft 934 protrudes radially and is fitted with either a first adsorption block 92 or a second adsorption block 121, secured by bolts and sealed with an O-ring. An air passage 932 is provided within the connecting shaft 934. The lower end of the air passage 932 communicates with the first adsorption block 92, and the upper end extends radially from the connecting shaft 934, connecting to a vacuum pump via a connector and pipeline. This allows the first adsorption block 92 to adsorb the fixed frame 4 under vacuum adsorption, and the second adsorption block 121 to adsorb the skeleton 3.

[0030] A top frame 933 is provided on the upper side of the pressure plate 93. A screw 935 passes downward through the top frame 933 and is threadedly connected to the upper end of the connecting shaft 934. A spring 95 is sleeved on the screw 935. The upper end of the spring 95 abuts against the top radial extension plate of the screw 935, and the lower end abuts against the connecting shaft 934, thereby achieving an elastic connection between the connecting shaft 934 and the pressure plate 93, so that the first adsorption block 92 and the second adsorption block 121 have a buffer space for vertical floating. When the first adsorption block 92 adsorbs the fixing frame 4 or the second adsorption block 121 adsorbs the skeleton 3, the first adsorption block 92 and the second adsorption block 121 are buffered upward under the action of the spring 95, thereby avoiding the impact of the first adsorption block 92 on the skeleton 3 when it moves downward to adsorb, and avoiding the impact of the second adsorption block 121 on the fixing frame 4.

[0031] Since the stroke of cylinder 94 is generally fixed, and the strokes of the adsorption action of the adsorption block and the downward action of the cylinder are inconsistent, the two actions will not coordinate, resulting in excessive pressure due to the shorter stroke. Therefore, in this embodiment, handles 96 are symmetrically arranged on the left and right sides of the pressure plate 93. The handles 96 are for manual gripping to manually drive the pressure plate 93 to rise and fall. Cylinder 94 is installed on the top of the mounting plate 90, with the driving end of cylinder 94 facing downward. During assembly, the pressure plate 93 is first manually driven to move downward, so that the fixing frame 4 adsorbs the skeleton 3, or the sleeve 5 adsorbs the base 1; then cylinder 94 is activated, driving the piston rod to move downward, applying downward pressure to the pressure plate 93, so that the fixing frame 4 is locked and fixed to the skeleton 3, and the sleeve 5 is locked and fixed to the base 1.

[0032] When manually driving the pressure plate 93 to rise, it is not only laborious, but it is also difficult for the pressure plate 93 to maintain a stable rising position. Therefore, as Figure 11 As shown, a pulley 98 is also installed on the top of the mounting plate 90. A steel wire rope is wound around the pulley 98, with one end fixedly connected to the pressure plate 93 and the other end fixedly connected to the counterweight 99. When the operator releases the handle 96, the counterweight 99 pulls the pressure plate 93 up and resets via the steel wire rope.

[0033] Since the tooling plate is generally positioned on the support plate 91 by locating pins and secured by bolts, disassembling the tooling plate every time would increase labor intensity and reduce efficiency. Therefore, in this embodiment, when the first tooling plate 6 needs to be positioned on the support plate 91, the third tooling plate 8 remains fixed, and the first tooling plate 6 is engaged and limited to the upper end of the third tooling plate 8 by the locating pin 63. When the fifth tooling plate 11 needs to be positioned on the support plate 91, the fourth tooling plate 10 remains fixed, and the fifth tooling plate 11 is engaged and limited to the upper end of the fourth tooling plate 10 by the locating pin 63.

[0034] The assembly method in this embodiment is as follows: S1. Position the skeleton 3 in the positioning hole of the first tooling plate 6, and position the skeleton 3 at the lower end and the sleeve 5 at the upper end. S2. Position the second tooling plate 7 at the upper end of the first tooling plate 6; S3. Insert the elastic element 2 into the guide correction hole 71 of the second tooling plate 7, so that the elastic element 2 slides into the mounting hole 31 of the skeleton 3 along the guide correction hole 71. S4. Remove the second tooling plate 7; S5. Position the fixing bracket 4 in the positioning hole of the third tooling plate 8; S6. Manually drive the pressure plate 93 on the first pressing assembly 9 to move down, so that the first adsorption block 92 adsorbs the fixing frame 4, and drives the fixing frame 4 to move up and detach from the third tooling plate 8. S7. Position the first tooling plate 6, which is equipped with the skeleton 3 and the elastic element 2, at the upper end of the third tooling plate 8. S8. Start the cylinder 94 on the first pressing assembly 9. The piston rod moves down to apply pressure to the pressure plate 93, pressing the fixing frame 4 into the sleeve 5, so that the locking teeth at the lower end of the fixing frame 4 are engaged and fixed with the skeleton 3. S9. The cylinder 94 on the first pressing component 9 drives the pressure plate 93 to rise and reset. S10. Move the entire assembly of the skeleton 3, elastic element 2 and fixing frame 4 into the positioning hole of the fourth tooling plate 10, and position the skeleton 3 at the upper end and the sleeve 5 at the lower end. S11. Manually drive the pressure plate 93 on the second pressing assembly 12 to move down, so that the second adsorption block 121 adsorbs the skeleton 3, and drives the connecting whole to move up and detach from the fourth tooling plate 10. S12. The fifth tooling plate 11, which is equipped with the base 1, is positioned at the upper end of the fourth tooling plate 10. S13. Activate cylinder 94 on the second pressing assembly 12. The piston rod moves downward to apply pressure to the pressure plate 93, pressing the lower end of the sleeve 5 into and fixing it to the base 1, completing the assembly of the base 1, elastic element 2, frame 3, and fixing bracket 4. (Refer to...) Figure 8 .

[0035] Compared to existing technologies, the advantages of this embodiment are: 1. Multiple dedicated tooling plates are used to position and fix the frame 3, elastic element 2, fixing frame 4, sleeve 5, and base 1 respectively, and the pressing and snapping operations are completed in conjunction with the adsorption block of the pressing component. This invention replaces traditional manual assembly, reduces manual operation steps and alignment difficulty, improves assembly speed, and ensures the consistency of the assembly position of each component, reducing the product defect rate caused by human error. At the same time, compared with fully automatic production lines, this device has a simplified structure and does not require complex robotic arms, vision systems, or multi-system integration. Through the limiting design of the tooling plates and the universal adsorption pressing function of the pressing component, semi-automatic operation of key processes is achieved, significantly reducing the initial equipment R&D and manufacturing costs, debugging cycle, and subsequent maintenance costs. Modular tooling plates are easy to replace or adjust, making them more suitable for small and medium-sized enterprises or application scenarios with frequent product iterations. 2. Each tooling plate can be used independently or combined on the pallet 91 to adapt to the needs of different assembly stages. This modular design allows the device to flexibly adjust the process sequence or adapt to different product models, enhancing the adaptability and scalability of the production line. 3. The device uses a tooling plate as a carrier. Operators only need to place the parts and replace the tooling plate. The force control links such as pressing are automatically completed by the pressing component, which reduces labor intensity and operational risks.
