Description

Technical Field

[0001] The present invention belongs to the technical field of product detection devices, and specifically relates to a product detection device for supporting a connector stamping die. Background Art

[0002] Connectors are a very common type of interface component in electronics and electrical engineering. They are widely used in audio / video equipment, industrial control, aerospace, medical equipment, and the military field. After the female connector is stamped, it needs to be subjected to a plugging and unplugging test to determine whether the resistance is qualified when a qualified male connector is inserted into the female connector, and ensure that the plugging and unplugging force is within the specified range. Excessive plugging and unplugging force may cause damage to the contact parts or shorten the service life of the connector, while too small plugging and unplugging force may lead to poor contact.

[0003] In the manufacturing process of female connectors, stamping is one of the core processes. However, during this process, the metal sheet undergoes plastic deformation under the high pressure of the die, and inevitably generates tiny metal debris. In addition, as the service time of the stamping die increases, fine particulate matter gradually appears on its surface due to friction and wear. The above debris and particulate matter are extremely likely to adhere to or remain on the inner wall and key contact surfaces of the female connector. Subsequently, during product detection (especially plugging and unplugging force testing), if these residues are not effectively removed, the debris and residues adhering to the inner wall will be sandwiched between the mating gaps of the male and female connectors. This foreign matter interference will significantly change the friction state of the contact surface, resulting in abnormal fluctuations or deviations in the plugging and unplugging force test data, and unable to accurately reflect the true physical properties of the product, thus causing misjudgment, seriously affecting the yield rate and quality control of female connectors. Therefore, a product detection device for supporting a connector stamping die is needed to solve the above problems. Summary of the Invention

[0015] The beneficial effects of this invention are as follows: 1. In this invention, by integrating a pneumatic cleaning function into the testing device, the insertion / removal testing and cleaning operations are carried out simultaneously, effectively solving the problem of interference of stamping debris on the test results. Specifically, the controller coordinates the operation of the first electric push rod and the fan. When the male insertion / removal test head enters the connector female head with the moving cylinder, the fan blows air into the connection cavity through the air blowing pipe. The airflow is obliquely blown out through the inclined air outlet located on the lower side of the male insertion / removal test head. This airflow design can accurately impact the inner wall of the connector female head, effectively blowing away the attached debris and residue from the contact surface. At the same time, the suction pipe generates negative pressure through the air collection hood, quickly sucking out the gas mixed with residue. This "blowing and suction combination" and oblique impact cleaning method can ensure that the contact area between the male insertion / removal test head and the connector female head is thoroughly cleaned before insertion, avoiding abnormal friction caused by debris, thereby ensuring the accuracy of the insertion / removal test data and greatly improving the reliability of connector female head product testing.

[0016] 2. In this invention, through ingenious mechanical linkage and control logic, automatic unloading and accurate classification of good and defective connector female heads after inspection are achieved, greatly improving the automation level of the inspection line. Specifically, after the insertion and removal test is completed and the product is determined to be qualified, the controller first drives the second electric push rod to release the clamp, and then starts the second drive motor. The second drive motor drives the push frame to move towards the mounting frame through the second screw. During the movement, the push frame first squeezes the inclined surface of the limiting seat, forcing the limiting seat to move downward to release the vertical limitation on the connector female head. Then the push frame continues to advance, pushing the qualified connector female head directly into the collection box. Conversely, if the product is determined to be defective, the controller controls the push frame to first perform the action of moving away from the mounting frame, and cooperates with subsequent steps to achieve the diversion and collection of defective products. This device not only achieves fully automatic unloading after inspection, but also avoids the error of manual sorting through precise motor control and mechanical cooperation, ensuring the accuracy, efficiency and reliability of the classification operation.

[0017] 3. In this invention, the synergistic cooperation between the limiting seat and the clamping plate achieves a double-stable fixation of the connector female head, effectively improving the stability of the testing process. Specifically, after the connector female head is moved to the placement seat, the second drive motor controls the push frame to move backward and reset. At this time, the elastic restoring force of the first spring automatically drives the limiting seat to rise and precisely fit onto the outside of the connector female head, forming a preliminary circumferential limit. Subsequently, the second electric push rod moves, driving the clamping plate to perform lateral clamping on the connector female head. This three-dimensional fixing method of "outer ring limiting + side clamping" can effectively prevent the connector female head from tilting or shifting due to uneven force during the insertion and removal test, thereby ensuring the stable operation of the insertion and removal test and guaranteeing the accuracy of the test data.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 10 As shown, a product testing device for connector stamping dies includes a mounting base 1; two mounting brackets 2 are mounted on the mounting base 1, and a first electric push rod 3 is fixedly connected to the upper end of the mounting bracket 2. A force sensor 4 is mounted on the bottom end of the first electric push rod 3, and a insertion / removal test male head 5 is mounted below the force sensor 4. A movable cylinder 6 is slidably connected inside the insertion / removal test male head 5, and a guide rod 11 is mounted on the movable cylinder 6. A guide seat 12 is slidably connected to the outside of the guide rod 11 and is installed on the inner wall of the insertion / removal test male head 5. A connection cavity 7 is opened inside the movable cylinder 6, and a connection cavity 7 is opened at the bottom of the movable cylinder 6. The device has several air vents 10, which are connected to the connecting cavity 7. An air blowing pipe 8 is connected through the movable cylinder 6 and the insertion / removal test male head 5. The air blowing pipe 8 is connected to the connecting cavity 7. An air collecting hood 13 is provided inside the movable cylinder 6. An air suction pipe 14 is connected to the air collecting hood 13. The air suction pipe 14 is connected through the insertion / removal test male head 5. A support rod 17 is installed on the upper surface of the mounting base 1 at the position corresponding to the insertion / removal test male head 5. A placement seat 18 is installed at the top of the support rod 17. A connector female head 19 is provided on the placement seat 18. A feeding mechanism is installed on the mounting base 1 at the position corresponding to the placement seat 18.

[0022] When testing the female connector 19, connect an external blower to the air blowing pipe 8 and an external blower to the air suction pipe 14. Directly control the two blowers and the first electric push rod 3 via the controller. The first electric push rod 3 extends, causing the male connector 5 to move downwards. When the male connector 5 moves downwards, it causes the bottom end of the movable cylinder 6 to enter the female connector 19. At this time, the blower blows gas into the connection cavity 7 through the air blowing pipe 8, and at the same time, the gas in the connection cavity 7 is blown downwards into the female connector 19 through the air outlet 10. Then the gas and residue are removed. The air is drawn out by the fan through the air collection hood 13 and the suction pipe 14. Since the air blowing position on the inner wall of the connector female head 19 is below the insertion and removal test male head 5, the contact part between the insertion and removal test male head 5 and the connector female head 19 is cleaned, ensuring that there are no debris or residues at the connection between the connector female head 19 and the insertion and removal test male head 5. This ensures that the insertion and removal test male head 5 and the connector female head 19 are not affected by debris or residues during the insertion and removal process, thereby ensuring the accuracy of the measurement results during the insertion and removal test and making the product testing of the connector female head 19 more reliable.

[0023] like Figures 5-7 As shown: Several air outlets 10 are arranged equidistantly in a circle, and the air outlets 10 are inclined outward along the axis of the movable cylinder 6.

[0024] The blower blows gas into the connection cavity 7 through the air pipe 8. At the same time, the gas in the connection cavity 7 is blown downward into the connector female head 19 through the air outlet 10. At this time, the gas flows out along the inclined air outlet 10, so that the gas impacts the inner wall of the connector female head 19 at an angle, so that the gas can make smooth contact between the connector female heads 19, and the impact force on the debris and residues adhering to the inner wall is greater, so that the debris and residues are cleaned more thoroughly.

[0025] like Figure 7 As shown: The inner wall of the connecting cavity 7 has a spiral groove 9.

[0026] When the gas flows downward through the connecting cavity 7, it is guided by the spiral groove 9 to form a spiral airflow. As the spiral airflow flows downward along the air outlet 10, it rotates in a circumferential direction against the inner wall of the connector female head 19. The airflow impacts the debris and residue adhering to the inner wall of the connector female head 19 at multiple angles, resulting in a better impact cleaning effect on the residue.

[0027] like Figure 6 As shown: A mounting base 15 is installed on the inner wall of the male connector 5 for insertion and removal testing. A pressure sensor 16 is fixedly connected to the lower part of the mounting base 15. The pressure sensor 16 is electrically connected to the controller.

[0028] After the movable cylinder 6 is squeezed and moved to the pressure sensor 16 by the inner wall of the connector female head 19, the insertion and removal test male head 5 contacts the inner bottom wall of the connector female head 19. Then, the pressure sensor 16 controls the fan to cut off the power through the controller, automatically stopping the airflow in the movable cylinder 6, so that the air blowing cleaning in the test process can be stopped automatically, achieving the purpose of energy saving.

[0029] like Figures 3-4 As shown: A guide sleeve 20 is vertically slidably connected to the outside of the support rod 17. A limiting seat 21 is fixedly connected to the outside of the guide sleeve 20. The limiting seat 21 is sleeved on the outside of the connector female head 19. A first spring 22 is fixedly connected to the bottom of the limiting seat 21. An extension ring 23 is installed at the bottom end of the first spring 22. The extension ring 23 is installed on the surface of the support rod 17.

[0030] After the connector female head 19 is moved onto the placement seat 18, the second drive motor 37 is controlled to work. The second drive motor 37 controls the second screw 38 to rotate, thereby controlling the second threaded cap 40 and the push frame 43 to move away from the mounting bracket 2. At the same time, the first spring 22 drives the limiting seat 21 to move upward, thereby enabling the limiting seat 21 to be fitted over the connector female head 19 to limit the connector female head 19 and prevent the connector female head 19 from tilting during the insertion and removal test, thus ensuring the stability of the insertion and removal test process.

[0031] like Figure 4 As shown: Two second electric push rods 25 are installed inside the limiting seat 21. The ends of the second electric push rods 25 are fixedly connected to clamps 24. The clamps 24 are attached to the surface of the connector female head 19 and are arc-shaped.

[0032] After the connector female head 19 is moved onto the placement seat 18, the second drive motor 37 is controlled to work. The second drive motor 37 controls the second screw 38 to rotate, thereby controlling the second threaded cap 40 and the push frame 43 to move away from the mounting bracket 2. At the same time, the first spring 22 drives the limiting seat 21 to move upward, so that the limiting seat 21 is sleeved on the outside of the connector female head 19. Then, the controller controls the second electric push rod 25 to work. At this time, the second electric push rod 25 drives the clamping plate 24 to clamp the outside of the connector female head 19, so that the connector female head 19 is stably clamped. This avoids the situation where the male head 5 is pulled out of the connector female head 19 too quickly during the subsequent insertion and removal test, which would lift the connector female head 19. This makes the insertion and removal test process smoother and more stable, thereby ensuring the accuracy of the insertion and removal test process.

[0033] like Figure 1 and Figure 9As shown: The feeding mechanism includes a material bridge 26, an electric slider 27 is installed under the material bridge 26, an electric slide rail 44 is slidably connected to the electric slider 27 and mounted on the mounting base 1, a sliding hole 28 is opened on the side of the material bridge 26, a first drive motor 30 is installed on the back of the material bridge 26, a first screw 31 is fixedly connected to the output shaft of the first drive motor 30, a first threaded cap 32 is threadedly connected to the first screw 31, and a push plate 29 is fixedly connected to the side of the first threaded cap 32.

[0034] When the connector female head 19 on the placement seat 18 is removed and the limiting seat 21 is pressed down to the upper surface flush with the placement seat 18, the controller controls the first drive motor 30 to work. At this time, the first drive motor 30 drives the first screw 31 to rotate, thereby the first screw 31 drives the first threaded cap 32 and the push plate 29 to move forward, which in turn causes the push plate 29 to push the connector female head 19 forward until the connector female head 19 in the material bridge 26 is pushed onto the placement seat 18. Then, the controller controls the electric slider 27 in the electric slide rail 44 to move backward, thereby driving the connector female head 19 in the material bridge 26 to the rear side of the limiting seat 21, automatically completing the feeding process of the connector female head 19, making the feeding operation of the connector female head 19 automated and efficient, and with higher feeding efficiency.

[0035] like Figure 1 and Figure 8 As shown: Two collection frames 33 are provided under the limiting seat 21. The side wall of the collection frame 33 is provided with a connection port 34 corresponding to the position of the limiting seat 21. The front of the collection frame 33 away from the mounting frame 2 is equipped with a second drive motor 37. The output shaft of the second drive motor 37 is fixedly connected to a second screw 38. The end of the second screw 38 is provided with a bearing seat 39. The bearing seat 39 is installed on the front of the collection frame 33 close to the mounting frame 2. The second screw 38 is externally threaded with a second threaded cap 40. The back of the second threaded cap 40 is fixedly connected to a contact plate 41. The contact plate 41 is attached to the front of the collection frame 33. An intermediate rod 42 is installed on the second threaded cap 40. The rear end of the intermediate rod 42 is fixedly connected to a push frame 43.

[0036] After the male connector 5 separates from the female connector 19 during the insertion / removal test, and the female connector 19 passes the test, the controller controls the second electric push rod 25 to work, causing the clamping plate 24 to separate from the female connector 19. Then, the controller controls the first electric push rod 3 to stop working, and then controls the second drive motor 37 to work. At this time, the second drive motor 37 drives the second screw 38 to rotate, and then the second screw 38 drives the second threaded cap 40 and the push frame 43 to move closer to the mounting bracket 2, so that the push frame 43 presses against the inclined surface of the limiting seat 21. At this time, the limiting seat 21 moves downward until it separates from the female connector 19. Then, the push frame 43 continues to move, pushing the female connector 19 closer to the mounting bracket 2, and then pushing... The frame 43 pushes the qualified connector female head 19 into the collection frame 33, and then controls the second drive motor 37 to work. The second drive motor 37 drives the second screw 38 to rotate. When the second screw 38 rotates, it will drive the second threaded cap 40 and the push frame 43 to move away from the mounting bracket 2 until the side plate of the push frame 43 away from the mounting bracket 2 just passes the placement seat 18. Then the second drive motor 37 is controlled to stop working. If the connector female head 19 is detected to be unqualified, the second drive motor 37 is controlled to drive the push frame 43 to move away from the mounting bracket 2 first. The remaining actions are similar to the above actions, realizing the automatic removal of the tested connector female head 19 and the classification of qualified and unqualified products. The insertion and removal test process has a higher degree of automation and the classification is more accurate and efficient.

[0037] like Figure 10 As shown: Four telescopic rods 35 are installed under the collection frame 33. The bottom end of the telescopic rod 35 is fixedly connected to the mounting base 1. A second spring 36 is provided on the outer sleeve of the telescopic rod 35. The second spring 36 is installed under the collection frame 33.

[0038] When the connector female head 19 on the placement seat 18 is pushed into the collection frame 33, the weight of the connector female head 19 acts on the collection frame 33. At this time, the weight will press the telescopic rod 35 and the second spring 36 to shorten, thereby causing the second spring 36 to buffer the falling process of the connector female head 19, thus avoiding the impact damage between the connector female head 19 and the collection frame 33, making the unloading and collection process of the connector female head 19 safer.

[0039] like Figures 3-4 As shown: The placement seat 18 is equipped with an anti-slip layer, and the anti-slip layer is made of anti-slip gel pad.

[0040] When the connector female head 19 is placed on the placement seat 18, the anti-slip gel pad increases the friction between the connector female head 19 and the placement seat 18, making it less likely for the connector female head 19 to slide horizontally. This increases the stability of the connector female head 19 during the insertion and removal test, making the insertion and removal test more stable and ensuring the smooth progress of the insertion and removal test process.

[0041] When testing the female connector 19 during operation, an external blower is connected to the air blowing pipe 8 and the air suction pipe 14. The controller directly controls the operation of the two blowers and the first electric push rod 3. The first electric push rod 3 extends, causing the male connector 5 to move downwards. When the male connector 5 moves downwards, it causes the bottom end of the movable cylinder 6 to enter the female connector 19. At this time, the blower blows air into the connection cavity 7 through the air blowing pipe 8, and at the same time, the air in the connection cavity 7 is blown downwards into the female connector 19 through the air outlet 10. In head 19, the gas is blown onto the inner wall of the connector female head 19, thereby blowing off the debris and residue on the inner wall of the connector female head 19. The gas flows into the interior of the movable cylinder 6, and then the gas and residue are drawn out by the fan through the gas collection hood 13 and the suction pipe 14. Since the air blowing position on the inner wall of the connector female head 19 is below the insertion test male head 5, the contact part between the insertion test male head 5 and the connector female head 19 is cleaned, ensuring that there are no debris or residue at the connection between the connector female head 19 and the insertion test male head 5. When the movable cylinder 6 is inserted into the inner bottom wall of the connector female head 19, the movable cylinder 6 is pushed upward inside the insertion / removal test male head 5. Then, when the movable cylinder 6 moves to the pressure sensor 16, the controller controls the fan to stop working until the insertion / removal test male head 5 is completely inserted into the connector female head 19. During the insertion process, the mechanical sensor 4 detects the resistance during insertion. After the insertion process measurement is completed, the controller controls the first electric push rod 3 to shorten. The first electric push rod 3 drives the insertion / removal test male head 5 to pull out of the connector female head 19. The mechanical sensor 4 measures the resistance during pull-out, thus completing the insertion / removal test process of the connector female head 19. After the male connector 5 is separated from the female connector 19 during the insertion / removal test, and the female connector 19 passes the test, the controller controls the second electric push rod 25 to work, causing the clamping plate 24 to separate from the female connector 19. Then, the controller controls the first electric push rod 3 to stop working, and then controls the second drive motor 37 to work. At this time, the second drive motor 37 drives the second screw 38 to rotate, and then the second screw 38 drives the second threaded cap 40 and the push frame 43 to move closer to the mounting bracket 2, thereby causing the push frame 43 to press against the inclined surface of the limiting seat 21. At this time, the limit seat 21 moves downward until it separates from the connector female head 19. At this time, the push frame 43 continues to move and pushes the connector female head 19 closer to the mounting bracket 2. Then the push frame 43 pushes the qualified connector female head 19 into the collection box 33. Then the second drive motor 37 is controlled to work. The second drive motor 37 drives the second screw 38 to rotate. When the second screw 38 rotates, it will drive the second threaded cap 40 and the push frame 43 to move away from the mounting bracket 2 until the side plate of the push frame 43 away from the mounting bracket 2 just passes the placement seat 18. Then the second drive motor 37 is controlled to stop working. Then, the controller controls the first drive motor 30 to work, which drives the first screw 31 to rotate. When the first screw 31 rotates, it controls the first threaded cap 32 push plate 29 to move forward. As the push plate 29 moves forward, it pushes the connector female head 19 forward until the connector female head 19 in the material bridge 26 is pushed onto the placement seat 18. Then, the controller controls the electric slide rail 44 to move backward, which drives the connector female head 19 in the material bridge 26 to the rear side of the limiting seat 21. Then, the controller controls the second drive motor 37 to work, which controls the second screw 38 to rotate, thereby controlling the second threaded cap 40 and the push frame 43 to move away from the mounting bracket 2. At the same time, the first spring 22 drives the limiting seat 21 to move upward, thereby enabling the limiting seat 21 to be fitted over the connector female head 19 until the push frame 43 separates from the limiting seat 21. Then, the controller controls the second drive motor 37 to stop working. Then, the above process is repeated to achieve the insertion and removal test of the connector female head 19 one after another.
