Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sensor detection equipment, in particular to a high-pressure detection device for a sensor shell hole. BACKGROUND

[0002] A sensor shell is a carrier for mounting parts on a sensor, which is usually formed by printing or injection molding. Figure 1 A sensor shell comprises a sensor shell body 01, two through grooves 02 are sequentially formed in the sensor shell body 01 along the height direction. During the manufacturing of the sensor shell, due to the unevenness of the material or errors in the manufacturing process, holes are inevitably left on the sensor shell. The sensor shell with holes is unqualified, and therefore, after the production of the sensor shell is completed, workers need to screen out the sensor shell with holes.

[0003] The current detection method for the holes of the sensor shell mainly relies on manual operation. Workers need to frequently manually turn the direction of the sensor shell and directly observe the internal condition by naked eyes, and then screen out the sensor shell with holes. However, the traditional detection method has the following obvious defects: on the one hand, the efficiency of manual operation is extremely low; on the other hand, for the holes with small sizes, workers cannot observe the holes by naked eyes due to the physiological limitation of the eyesight, thereby reducing the detection accuracy.

[0004] Therefore, the detection method for screening the holes of the sensor shell by manual operation has low detection efficiency and accuracy, and has obvious defects. CONTENT OF THE INVENTION

The automatic detection of the hole of the sensor shell is realized by such an arrangement, and the worker can judge whether the sensor shell is qualified by whether the short-circuit alarm signal is triggered, without the worker repeatedly rotating the sensor shell and judging by the naked eye, thereby improving the detection efficiency and accuracy of the sensor shell.

Such an arrangement realizes the limiting of sensor shells of different width specifications, thereby improving the applicability of the detection device.

[0013] Optionally, the output shaft of each cylinder is provided with a sliding block, and the copper bar is detachably connected to the sliding block through a connecting bolt.

[0018] By adopting the technical scheme, in the detection process, the detection grating monitors the situation of the detection area, when the worker or foreign matter accidentally enters the detection area during the detection process, the detection grating rapidly transmits the detected signal to the control system, and the control system cuts off the power supply of the high-voltage tester after receiving the signal, so that the high-voltage detection process is stopped instantaneously, the electric shock of the worker or the damage of the equipment caused by accidental collision is effectively prevented, and the personal safety of the worker and the normal operation of the equipment are ensured.

DETAILED DESCRIPTION

[0034] The following will be described in detail in combination with the accompanying Figures 1-6 The application will be further described in detail.

[0035] The embodiment of the application discloses a high-voltage detection device for a sensor shell hole.

[0036] Embodiment 1

[0037] Reference Figure 1 and Figure 2The utility model provides a kind of high pressure detection device of sensor shell hole, including workbench 1, workbench 1 is placed on ground, and workbench 1 is detachably connected with mounting seat 2 by bolt, mounting seat 2 is equipped with the placement slot 21 for placing sensor shell 01, and workbench 1 is equipped with detection assembly 3 and fixed assembly 4, before detection, sensor shell 01 is fixed by fixed assembly 4, subsequently, the hole in sensor shell 01 is detected by detection assembly 3.

[0038] With reference to Figure 1 、 Figure 2 and Figure 3 , detection assembly 3 includes two cylinders 31 fixedly installed on workbench 1, two cylinders 31 are respectively arranged at the two sides of mounting seat 2, the axis of two cylinders 31 is in the same straight line with the axis of sensor, and the output shaft of each cylinder 31 is fixedly connected with sliding block 5; each sliding block 5 is detachably connected with copper bar 32 by connecting bolt 51; two copper bars 32 are one-to-one corresponding with two through grooves 02; the area of copper bar 32 is same with the corresponding through groove 02 and is slidingly connected in the corresponding through groove 02; high pressure tester 33 is fixedly installed on workbench 1; high pressure tester 33 is electrically connected to two copper bars 32; high pressure tester 33 is prior art, and its principle will not be repeated in the embodiment.

[0039] With reference to Figure 1 、 Figure 2 and Figure 3 , fixed assembly 4 includes positioning frame 41 fixedly installed on mounting seat 2, positioning frame 41 is fixedly installed with fixed cylinder 42 on the top, the output shaft of fixed cylinder 42 is fixedly connected with fixed plate 43, and the surface of fixed plate 43 towards mounting seat 2 is equipped with fixed groove (not shown in the figure) adapting sensor shell 01, and sensor shell 01 is slidingly fitted with fixed groove.

[0040] In the detection of the sensor shell 01, the worker first places the sensor shell 01 in the placing groove 21, which provides preliminary positioning for the sensor shell 01, and then the high-voltage tester 33 is started and power is supplied to the two copper bars 32. After the copper bars 32 are powered on, the fixed cylinder 42 is first started, and the fixed plate 43 is driven to move downward by the fixed cylinder 42. When the top surface of the sensor shell 01 abuts against the inner wall of the fixed groove, the fixed plate 43 is covered above the sensor shell 01, so that the fixed plate 43 limits and fixes the sensor shell 01 from multiple directions. Then the two cylinders 31 are started at the same time, and the cylinders 31 drive the two copper bars 32 to be inserted into the two through grooves 02 respectively. When there is a hole in the sensor shell 01, the high-voltage electricity on the copper bar 32 passes through the hole and sends a short-circuit alarm signal to the high-voltage tester 33. When there is no hole in the sensor shell 01, the current normally flows between the copper bars 32 and cannot trigger a short-circuit alarm signal. This arrangement realizes automatic detection of the hole of the sensor shell 01. The worker only needs to judge whether the sensor shell 01 is qualified by whether the short-circuit alarm signal is triggered, without the need for the worker to repeatedly rotate the sensor shell 01 and judge by the naked eye, thereby improving the detection efficiency and accuracy of the sensor shell 01.

[0041] When the copper bars 32 are worn, deformed or need to be replaced, the worker unscrews the connecting bolts 51, removes the damaged copper bars 32 from the sliding block 5, and then places the new copper bars 32 on the sliding block 5 and tightens the connecting bolts 51 again, thereby completing the replacement process of the copper bars 32. This arrangement improves the convenience of worker operation and ensures the stable progress of the detection process.

[0042] Referring to Figure 1 , Figure 2 and Figure 3 , the mounting seat 2 is fixedly installed with a laser sensor 6, and the emitting part of the laser sensor 6 is arranged towards the placing groove 21. The laser sensor 6 can monitor in real time and accurately whether the sensor shell 01 is correctly placed on the mounting seat 2, thereby triggering the automatic start of the subsequent detection program, thereby improving the automation of the detection process and effectively avoiding detection omission or delay due to human operation negligence.

[0043] Referring to Figure 1 , Figure 2 and Figure 3The opposite sides of the workbench 1 are fixedly provided with detection gratings 7, which are electrically connected to the high-voltage tester 33 through the control system. During detection, the detection grating 7 monitors the situation of the detection area. When a worker or a foreign object accidentally enters the detection area during detection, the detection grating 7 rapidly transmits the detected signal to the control system. After receiving the signal, the control system cuts off the power supply of the high-voltage tester 33, thereby instantaneously stopping the high-voltage detection process, effectively preventing electric shock or damage to the equipment due to accidental collision, and ensuring the personal safety of the workers and the normal operation of the equipment.

[0044] The implementation principle of the high-voltage detection device for the sensor shell hole in the embodiment of the application is as follows: when the sensor shell 01 is detected, the worker first places the sensor shell 01 in the placement groove 21, which provides preliminary positioning for the sensor shell 01. Then the high-voltage tester 33 starts and supplies power to the two copper bars 32. After the copper bars 32 are powered on, the fixed cylinder 42 is first started. The fixed cylinder 42 drives the fixed plate 43 to move downward. When the top surface of the sensor shell 01 abuts against the inner wall of the fixed groove, the fixed plate 43 is arranged above the sensor shell 01, so that the fixed plate 43 limits and fixes the sensor shell 01 from multiple directions. Then the two cylinders 31 are simultaneously started. The cylinders 31 drive the two copper bars 32 to be inserted into the two through grooves 02, respectively. When there is a hole in the sensor shell 01, the high-voltage electricity on the copper bar 32 passes through the hole and sends a short-circuit alarm signal to the high-voltage tester 33. When there is no hole in the sensor shell 01, the current normally flows between the copper bars 32 and cannot trigger a short-circuit alarm signal. In this way, automatic detection of the hole of the sensor shell 01 is realized. The worker can determine whether the sensor shell 01 is qualified by whether the short-circuit alarm signal is triggered, without the need for the worker to repeatedly rotate the sensor shell 01 and determine by the naked eye, thereby improving the detection efficiency and accuracy of the sensor shell 01.

[0045] Embodiment 2

[0046] With reference to Figure 1 and Figure 4 The difference between the embodiment of the application and embodiment 1 is that the inner bottom wall of the placement groove 21 is provided with a sliding groove 8, the cross section of the sliding groove 8 is square and the length direction is perpendicular to the moving direction of the copper bar 32. The fixed assembly 4 includes two clamping plates 44 which are slidingly connected in the sliding groove 8. A bidirectional screw rod 45 is rotatably connected in the sliding groove 8. The two clamping plates 44 are threadedly connected to two opposite sections of the bidirectional screw rod 45. One end of the bidirectional screw rod 45 extends out of the mounting base 2 and is coaxially fixedly connected with a rotating wheel 46. The rotating wheel 46 is rotatably connected to the outer surface of the mounting base 2.

[0047] The implementation principle of Example 2 is as follows: When the width specification of the sensor housing 01 changes, the worker rotates the rotating wheel 46. The rotation of the rotating wheel 46 drives the bidirectional lead screw 45 to rotate. Under the restriction of the cross-section of the sliding groove 8, the clamping plate 44 cannot rotate in the sliding groove 8. Therefore, the rotation of the bidirectional lead screw 45 causes the two clamping plates 44 to move towards each other and gradually approach the sensor housing 01. When both clamping plates 44 abut against the outer surface of the sensor housing 01, the sensor housing 01 is limited. This setting realizes the limitation of sensors with different width specifications and improves the applicability of the detection device.

[0048] Example 3

[0049] Reference Figure 1 , Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that a dust collection assembly 9 is provided on the workbench 1. The dust collection assembly 9 includes a dust collection plate 91 fixedly installed on the workbench 1. A receiving groove 10 is opened on the dust collection plate 91 to slide with the sensor housing 01. An ejection spring 11 is fixedly connected to the inner bottom wall of the receiving groove 10. A support plate 12 is fixedly connected to the other end of the ejection spring 11. The support plate 12 is slidably connected inside the receiving groove 10. In the natural state of the ejection spring 11, the top of the sensor housing 01 placed on the support plate 12 extends to the outside of the receiving groove 10.

[0050] Reference Figure 1 , Figure 5 and Figure 6 The inner wall of the receiving groove 10 is provided with a dust collection groove 101 corresponding to the two through grooves 02. When the top of the sensor housing 01 is flush with the surface of the dust collection plate 91, the dust collection groove 101 and the corresponding through groove 02 are connected to each other. The dust collection plate 91 is provided with a dust collection chamber 911 that is connected to the two dust collection grooves 101. An air suction pump 92 is fixedly installed on the workbench 1. The suction end of the air suction pump 92 is connected to the dust collection chamber 911 through the air pipe 93.

[0051] The implementation principle of Example 3 is as follows: Before testing the sensor housing 01, the sensor housing 01 is placed in the receiving groove 10, and then the sensor housing 01 is pressed so that the sensor housing 01 is completely embedded in the receiving groove 10. At this time, the ejector spring 11 is compressed, and the dust collection groove 101 is connected to the through groove 02. Then the suction pump 92 is started. The suction pump 92 draws the gas inside the dust collection chamber 911 through the air pipe 93, thereby creating a negative pressure environment at the dust collection groove 101. At this time, the dust particles remaining inside the sensor housing 01 are detached from the sensor housing 01 and are drawn into the dust collection chamber 911 through the through groove 02 and the dust collection groove 101. This setting realizes the effective cleaning of the sensor housing 01 before testing, avoids the occurrence of detection misjudgment due to dust particles clogging the holes, and improves the accuracy of testing.

[0052] After vacuuming is finished, the worker releases the force applied to the sensor housing 01, the pressure received by the ejector spring 11 disappears, the ejector spring 11 resets and pushes the support plate 12 upward, so that the top of the sensor housing extends outside the receiving groove 10. At this time, the operator only needs to lift the part of the sensor housing 01 that is exposed in the receiving groove 10 to remove the sensor housing 01. There is no need to use additional tools to go deep into the receiving groove 10 to pry out the sensor housing 01, which improves the convenience and efficiency of removing the sensor housing 01.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
