Description

Technical Field

[0001] This utility model relates to the field of pin pressure module technology, and in particular to a pin pressure module with pressure sensing. Background Technology

[0002] In the automotive connector manufacturing sector, with the rapid development of the automotive industry, the requirements for connector quality and performance are becoming increasingly stringent. This is especially true for automotive connectors with large terminals and diverse product types, where mass production presents numerous challenges to the manufacturing process.

[0003] The existing manufacturing process has significant problems. On the one hand, terminal defects occur frequently, such as dimensional deviations and surface imperfections, which directly affect the electrical and mechanical performance of the connector. On the other hand, plastic deformation is also a prominent issue. During the molding process, the plastic may deform due to factors such as mold precision and injection molding parameters, leading to dimensional deviations and deformation in the product. Furthermore, plastic blockage of holes is also a serious concern, as it severely hinders the normal assembly of pins and reduces the product yield.

[0004] For automotive connector products of this type, the assembly of each pin N with the plastic has strict interference requirements. After assembly, each pin N must withstand a pull-out force of 30N to 50N to ensure stable operation of the connector in the complex automotive environment. However, currently, there is a lack of effective process monitoring methods in the connector assembly process. If assembly abnormalities caused by process issues, such as terminal defects, dimensional mismatches caused by plastic deformation, deformation, and plastic blockage, cannot be detected in time at the final pressing station, these defective products will pose a serious threat to the safe operation of automobiles if they enter the market. In view of this, this utility model proposes a pin pressure module with pressure sensing. Utility Model Content

[0005] The purpose of this invention is to address the problem in the background art where, during the mass production of automotive connectors, process issues such as terminal defects, plastic deformation, and hole blockage, coupled with a lack of effective process monitoring during assembly, lead to difficulties in ensuring product quality. The resulting inferior products entering the market could threaten vehicle safety. This invention proposes a pin pressure module with pressure sensing.

[0006] The technical solution of this utility model is as follows: a pin pressure module with pressure sensing, including a base; a drive mechanism disposed on the base, on which a pressure sensor is installed, the drive mechanism being used to drive the pressure sensor to move; and a pressing component installed on the top of the base, the pressing component being pushed by the pressure sensor to realize the pressing of the terminal and monitor the pressure at the same time.

[0007] Optionally, the base includes a base plate, with two sets of support plates fixedly connected to the top of the base plate. The top of the two sets of support plates is fixedly connected to a mounting plate. The top of the mounting plate is equipped with two sets of side plates, and one end of the two sets of side plates is fixedly connected to a fixing plate.

[0008] Optionally, the drive mechanism includes a servo motor mounted on the side of the fixed plate away from the side plate. The output end of the servo motor passes through the fixed plate and is fixedly connected to a coupling. A lead screw is fixedly connected to the end of the coupling away from the servo motor. A threaded sleeve is threaded onto the lead screw. A moving block is mounted on the outer ring of the threaded sleeve. A connecting block is fixedly connected to the moving block. The pressure sensor is mounted on the side of the connecting block away from the servo motor.

[0009] Optionally, two sets of limiting seats are rotatably connected to the lead screw, and the two sets of limiting seats are respectively located on both sides of the threaded sleeve, and the limiting seats are fixedly connected between the two sets of side plates.

[0010] Optionally, the pressing assembly includes two sets of slide rails, which are respectively fixedly connected to the top of two sets of side plates. Multiple sets of sliders are slidably connected on the slide rails. A movable plate is fixedly connected to the top of the multiple sets of sliders. An installation block is installed on the top of the movable plate. A terminal pressing head is fixedly connected to the side of the installation block away from the servo motor.

[0011] Optionally, the movable plate has a through hole, and the movable block and the connecting block are slidably connected in the through hole. The pressure sensor is also located in the through hole, and the side of the pressure sensor away from the connecting block is in contact with the inner wall of the through hole.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention uses a pressure sensor to monitor the pressure during the pressing process in real time. When the pressure exceeds the preset range, the control module triggers an alarm, which can accurately detect assembly abnormalities caused by terminal defects, plastic deformation, etc., thereby promptly identifying unqualified products, preventing them from entering the market, and effectively improving product quality.

[0014] Furthermore, the pressure sensor is moved by the drive mechanism, which pushes the pressing component to press the terminal in and monitor the pressure. This allows process deviations to be detected in time during production, ensuring production stability and improving product qualification rate and reliability.

[0015] In summary, this utility model can effectively improve the quality of automotive connector products, prevent unqualified products from entering the market, ensure safe driving of automobiles, and optimize the production process to improve product qualification rate and reliability.

[0028] Example

[0029] like Figure 1 As shown, this utility model proposes a pressure sensor-equipped pin pressure module, including a base 1, which includes a base plate 11, the position of which is fixed. Two sets of support plates 12 are fixedly connected to the top of the base plate 11, and a mounting plate 13 is fixedly connected to the top of both sets of support plates 12. The mounting plate 13 is fixedly connected to the base plate 11 via the support plates 12. Two sets of side plates 14 are mounted on the top of the mounting plate 13, and a fixing plate 15 is fixedly connected to one end of each set of side plates 14. The positions of the side plates 14 and the fixing plate 15 are fixed.

[0030] For further details, please refer to Figure 1 and Figure 2 The aforementioned pin pressure module includes a drive mechanism 2 mounted on a base 1. A pressure sensor 3 is installed on the drive mechanism 2, which is used to move the pressure sensor 3. The drive mechanism 2 includes a servo motor 21 mounted on the side of the fixed plate 15 away from the side plate 14, and the position of the servo motor 21 is fixed. The output end of the servo motor 21 passes through the fixed plate 15 and is fixedly connected to a coupling 22. A lead screw 23 is fixedly connected to the end of the coupling 22 away from the servo motor 21. After the servo motor 21 starts, it drives the lead screw 23 to rotate through the coupling 22. A threaded sleeve 24 is threadedly connected to the lead screw 23. When the lead screw 23 rotates, it drives the threaded sleeve 24 to move along the length of the lead screw 23. A moving block 25 is fitted around the outer ring of the threaded sleeve 24, and the threaded sleeve 24 and the moving block 25 move synchronously. A connecting block 26 is fixedly connected to the moving block 25. The pressure sensor 3 is installed on the side of the connecting block 26 away from the servo motor 21 and is used to monitor the pressure. Two sets of limit seats 27 are rotatably connected to the lead screw 23. The two sets of limit seats 27 are located on both sides of the threaded sleeve 24. The limit seats 27 are fixedly connected between the two sets of side plates 14. The fixed position of the limit seats 27 makes the rotation of the lead screw 23 smooth.

[0031] Pressure sensor 3 transmits the monitored pressure to the control module. Each product injection can be set with two injection positions and speeds. Pressure range settings are added for both the primary and secondary positions, with an alarm triggered if the range is exceeded. For example, a position range can be set to reach 500N of pressure, with an alarm triggered if the range is exceeded. Product quality is controlled through pressure sensor 3.

[0032] Furthermore, the aforementioned pin pressure module also includes a pressing assembly 4 mounted on the top of the base 1. The pressing assembly 4 is pushed by the pressure sensor 3 to press the terminal in while simultaneously monitoring the pressure. The pressing assembly 4 includes two sets of slide rails 41, which are respectively fixedly connected to the top of the two sets of side plates 14, and the positions of the slide rails 41 are fixed. Multiple sets of sliders 42 are slidably connected to the slide rails 41, and a moving plate 43 is fixedly connected to the top of the multiple sets of sliders 42. The moving plate 43 moves smoothly under the limiting action of the slide rails 41 and the sliders 42. An mounting block 44 is mounted on the top of the moving plate 43, and the moving plate 43 drives the mounting block 44 to move when it moves. A terminal pressing head 45 is fixedly connected to the side of the mounting block 44 away from the servo motor 21. After moving, the terminal pressing head 45 contacts the terminal and realizes the insertion of the terminal. A through hole 46 is provided on the movable plate 43. The movable block 25 and the connecting block 26 are both slidably connected in the through hole 46. The threaded sleeve 24 moves synchronously with the movable block 25. Since the movable block 25 cannot rotate in the through hole 46, the rotation of the lead screw 23 will drive the threaded sleeve 24 and the movable block 25 to move. The pressure sensor 3 is also located in the through hole 46, and the side of the pressure sensor 3 away from the connecting block 26 is in contact with the inner wall of the through hole 46. When the pressure sensor 3 moves, one end contacts the inner wall of the through hole 46 and drives the movable plate 43 to move, while monitoring the pressure in real time.

[0033] In this embodiment, the servo motor 21 starts, and its output end rotates, driving the lead screw 23 to rotate via the coupling 22. Since the lead screw 23 is threadedly connected to the threaded sleeve 24, when the lead screw 23 rotates, the threaded sleeve 24 moves along the length of the lead screw 23. Because the moving block 25 moves synchronously with the threaded sleeve 24 and cannot rotate within the through hole 46, the rotation of the lead screw 23 drives the threaded sleeve 24 and the moving block 25 to move smoothly. The moving block 25 drives the pressure sensor 3 to move via the connecting block 26. During the movement, one end of the pressure sensor 3 contacts the inner wall of the through hole 46 and pushes the moving plate 43. Simultaneously, the pressure sensor 3 monitors the pressure in real time and transmits the monitored pressure data to the control module. The moving plate 43 moves smoothly under the limiting action of the slide rail 41 and the slider 42, driving the mounting block 44 and the terminal pressing head 45 closer to the terminal to be pressed in. When the terminal pressing head 45 contacts the terminal, pressure continues to be applied to insert the terminal, while the pressure sensor 3 monitors the pressure in real time.

[0034] The control module sets two pressing positions and speeds for each product pressing operation, and sets pressure ranges at the first and second positions. If the pressure detected by pressure sensor 3 exceeds the preset pressure range, such as exceeding the preset position range when the pressure reaches 500N, the control module will trigger an alarm, thereby controlling product quality through pressure sensor 3.

[0035] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
