Technical Field

[0001] The present application relates to the technical field of detection equipment, and in particular to a detection device. Background Art

[0002] During the production process of products with a bracket, the bracket will be produced into two parts, the frame and the base, and then the frame and the base will be assembled. In some products, electrical equipment such as monitors and lighting will be installed on the frame. In order to be able to connect the electrical equipment to electricity, it is necessary to run wires through the frame. One end of the wire is electrically connected to the electrical equipment, and the other end of the wire extends toward the end where the frame is connected to the base and passes through the frame, and the power connection end of the wire protrudes from the bottom end of the frame. A wire is also installed on the base, and one end of the wire forms a plug on the base that connects to the power connection end, and the other end of the wire is used to connect to an external power supply. After the external power supply is connected to the wire on the base, the electrical equipment can be powered.

[0003] The distance the power terminal protrudes from the frame affects whether the plug on the base and the power terminal on the frame can properly mate. If the power terminal protrudes too far, the plug on the base will not mate with the power terminal successfully or the connection will become loose. Therefore, it is necessary to measure the distance the power terminal protrudes from the frame. In related technologies, length measurement is generally performed manually using a vernier caliper, but manual measurement can lead to inaccurate readings, affecting measurement accuracy.

The driver can drive the detection part to move in the first direction, and the detection part moves towards the gap. If the protruding distance of the power connection end relative to the detection piece is short and the gap is large, the detection part can pass through the gap under the driving of the driver, indicating that the installation position of the power connection end is incorrect. If the protruding distance of the power connection end relative to the detection piece is normal and the gap is small, the detection part will abut against the power connection end under the driving of the driver and cannot pass through the gap, indicating that the installation position of the power connection end is correct.

In the specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0037] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the detection device according to the embodiment of the present application comprises a base 100, a detection part 200, a jig 300, a driver 400 and a sensor (not shown in the figure).

[0038] The jig 300 is arranged on the support surface 110 of the base 100, and is used to fix the to-be-detected piece 700. The electrical connection end 710 of the to-be-detected piece 700 is spaced apart from the support surface 110. The driver 400 is located on one side of the jig 300 in the first direction, and drives the detection part 200 to move in the first direction. The detection part 200 can pass through the gap 120 or abut against the electrical connection end 710. The sensor is used to sense whether the detection part 200 passes through the gap 120.

[0039] It can be understood that the to-be-detected piece 700 is placed on the jig 300, and the jig 300 can elevate the to-be-detected piece 700, so that the to-be-detected piece 700 does not directly contact the support surface 110 of the base 100, and the electrical connection end 710 at the lower end of the to-be-detected piece 700 is spaced apart from the support surface 110 of the base 100. The driver 400 can drive the detection part 200 to move in the first direction, and the detection part 200 moves towards the gap 120. If the protruding distance of the electrical connection end 710 relative to the to-be-detected piece 700 is short, and the gap is large, the detection part 200 can pass through the gap 120 under the driving of the driver 400, indicating that the installation position of the electrical connection end 710 is incorrect. If the protruding distance of the electrical connection end 710 relative to the to-be-detected piece 700 is normal, and the gap is small, the detection part 200 will abut against the electrical connection end 710 under the driving of the driver 400, and cannot pass through the gap 120, indicating that the installation position of the electrical connection end 710 is correct. The sensor can sense whether the detection part 200 passes through the gap 120, so as to judge whether the protruding distance of the electrical connection end 710 relative to the to-be-detected piece 700 is qualified, so as to judge whether the installation position of the electrical connection end 710 is accurate. In summary, the detection device of the present application can sense whether the detection part 200 can pass through the gap 120 between the electrical connection end 710 and the base 100 through the sensor, so as to automatically judge whether the installation position of the electrical connection end 710 is accurate, and realizes automatic detection, improves the detection efficiency and the detection accuracy.

[0040] Referring to Figure 1 , Figure 2 and Figure 5 , according to some embodiments of the present application, the jig 300 is provided with a receiving hole 310, which penetrates the upper and lower ends of the jig 300, and is used to pass through the to-be-detected piece 700.

[0041] It can be understood that the to-be-detected product can be placed into the receiving hole 310 from top to bottom, and the to-be-detected piece 700 passes through the receiving hole 310, which can limit the to-be-detected product.

[0042] Specifically, in the embodiment, the product to be detected is a rack body having a certain height, the accommodating hole 310 penetrates the upper end of the jig 300 so that the height of the rack body does not affect the use of the jig 300, and the accommodating hole 310 penetrates the lower end of the jig 300 to ensure that the electrical connection end 710 at the lower end of the detected piece 700 can form a gap 120 with the support surface 110 of the base 100.

[0043] Specifically, regarding the way the jig 300 fixes the detected piece 700, in the embodiment, the outer side of the detected piece 700 forms a flange, and after the detected piece 700 passes through the accommodating hole 310, the outer diameter of the flange is larger than the hole diameter of the accommodating hole 310, so the flange cannot pass through the accommodating hole 310. The flange abuts against the upper end surface of the jig 300, thereby limiting the downward movement of the detected piece 700 to form a gap 120 between the electrical connection end 710 and the base 100, and limiting the horizontal movement of the detected piece 700 through the accommodating hole 310. In other embodiments, the detected piece 700 can also be clamped by a cylinder cooperating with a clamping block to achieve the fixation of the detected piece 700.

[0044] Referring to Figure 2 , Figure 3 and Figure 5 , according to some embodiments of the present application, the jig 300 is provided with a first channel 320 extending in a first direction, one end of the first channel 320 penetrates the side of the jig 300 close to the driver 400 to form a first opening 321 on one side of the jig 300, and the other end of the first channel 320 penetrates the hole wall of the accommodating hole 310 to form a second opening 322 on the hole wall of the accommodating hole 310; wherein the detection part 200 can pass through the first opening 321, the first channel 320 and the second opening 322 in sequence.

[0045] It can be understood that under the drive of the driver 400, the detection part 200 can first pass through the first opening 321 into the first channel 320, then the detection part 200 moves along the first channel 320 towards the direction close to the accommodating hole 310, and passes out of the first channel 320 through the second opening 322 to enter the accommodating hole 310, so as to pass through the gap 120 or abut against the electrical connection end 710. It should be understood that the first channel 320 can guide the movement of the detection part 200 to ensure the direction of movement of the detection part 200 is accurate, and ensure that the detection part 200 can pass through the gap 120 or abut against the electrical connection end 710.

[0046] Specifically, there is a certain distance between the driving end of the actuator 400 and the fixture 300. The detection portion 200 is elongated, ensuring that it can pass through the gap 120 or abut against the power connection 710. Due to its length, the detection portion 200 is prone to shaking during movement. The first channel 320 is formed to guide the movement of the detection portion 200, ensuring its stability.

[0047] Specifically, regarding the specific form of the jig 300, in this embodiment, the jig 300 of the present application is block-shaped and has a large connection area with the base 100, thereby forming a first channel 320 for the detection unit 200 to pass through. In other embodiments, the jig 300 includes a support block and multiple support rods. The support block forms a receiving hole 310. One end of the support rod is connected to the support block and the other end is connected to the base 100, so that the support block is separated from the base 100. The detection unit 200 can pass between the two support rods to pass through the gap 120 or abut the power terminal 710.

[0048] Reference Figure 2 、 Figure 3 and Figure 5 According to some embodiments of the present application, the jig 300 is provided with a second channel 330 extending along the first direction, and one end of the second channel 330 passes through the hole wall of the accommodating hole 310 to form a third opening 331 on the hole wall of the accommodating hole 310, and the third opening 331 is opposite to the second opening 322; wherein, the detection part 200 passing through the gap 120 can enter the second channel 330 through the third opening 331.

[0049] It is understood that after the detection portion 200 passes through the gap 120, it can enter the second channel 330 through the third opening 331. Specifically, the aperture of the receiving hole 310 is relatively small. To prevent the detection portion 200 from colliding with the receiving hole 310 after passing through the gap 120 and affecting the sensor's judgment, the second channel 330 is added to allow the detection portion 200 to continue moving in the first direction after passing through the gap 120, thereby increasing the displacement of the detection portion 200 passing through the gap 120, ensuring accurate sensor sensing, and preventing the detection portion 200 from colliding with the inner wall of the receiving hole 310, which may cause damage to the detection portion 200.

[0050] Reference Figure 2 、 Figure 3 and Figure 5 According to some embodiments of the present application, the other end of the second channel 330 passes through the side of the jig 300 facing away from the driver 400 to form a fourth opening 332 on one side of the jig 300; wherein the detection part 200 entering the second channel 330 can pass through the fourth opening 332.

[0051] It is understood that the detection portion 200, after entering the second channel 330, can be further moved in the first direction under the drive of the driver 400 to pass through the fourth opening 332, thereby reducing the risk of the detection portion 200 colliding with the inner wall of the second channel 330. Furthermore, in some cases, whether the detection portion 200 has passed through the gap 120 can be determined by observing whether the detection portion 200 has passed through the fourth opening 332. This makes the determination simple and allows for dual verification by manual and sensor verification to improve detection accuracy.

[0052] Reference Figure 2 、 Figure 3 and Figure 5 According to some embodiments of the present application, the level of the bottom inner wall of the first channel 320 is higher than the level of the support surface 110 .

[0053] It can be understood that the horizontal height of the first channel 320 is set higher so that the horizontal height of the bottom inner wall surface of the first channel 320 is higher than the horizontal height of the support surface 110. As a result, the horizontal height of the detection part 200 can also be set higher, avoiding friction between the detection part 200 and the support surface 110, thereby reducing the risk of wear of the detection part 200.

[0054] Reference Figure 2 、 Figure 3 and Figure 5 According to some embodiments of the present application, the level of the bottom inner wall of the second channel 330 is higher than the level of the support surface 110 .

[0055] It is understood that the height of the second channel 330 is set higher, so that the height of the second channel 330 is consistent with the height of the first channel 320, thereby ensuring that the detection unit 200 passing through the gap 120 can enter the second channel 330. In addition, the height of the bottom inner wall of the second channel 330 is set higher than the height of the support surface 110. As a result, the height of the detection unit 200 is also set higher, avoiding friction between the detection unit 200 and the support surface 110, and reducing the risk of wear of the detection unit 200.

[0056] Reference Figure 2 and Figure 5 According to some embodiments of the present application, the vertical cross-section of the detection portion 200 is square.

[0057] It can be understood that the lower end surface of the power connection end 710 is substantially planar, and the vertical cross section of the detection part 200 is square-shaped, which facilitates the measurement of the thickness of the detection part 200, so as to set the thickness of the detection part 200 to an appropriate size, so that the detection part 200 can abut against the power connection end 710 when the installation position of the power connection end 710 is normal, and the detection part 200 can pass through the gap 120 when the installation position of the power connection end 710 is abnormal.

[0058] According to some embodiments of the present application, the sensor is a travel sensor, and the driver 400 is a pneumatic cylinder, and the travel sensor is used to sense the movement stroke of the piston rod of the pneumatic cylinder.

[0059] It can be understood that the piston rod of the pneumatic cylinder is connected with the detection part 200, and when the detection part 200 passes through the gap 120, the movement stroke of the piston rod is long enough to reach the sensing range of the travel sensor, so as to determine that the detection part 200 has passed through the gap 120. When the detection part 200 abuts against the power connection end 710, the movement stroke of the piston rod is short and cannot reach the sensing range of the travel sensor, so as to determine that the detection part 200 has not passed through the gap 120.

[0060] In other embodiments, the sensor can also be a pressure sensor arranged on the detection part 200, and when the detection part 200 abuts against the power connection end 710, the pressure sensed by the pressure sensor increases, so as to determine that the detection part 200 has not passed through the gap 120. When the detection part 200 passes through the gap 120, the pressure sensed by the pressure sensor is zero, so as to determine that the detection part 200 has passed through the gap 120.

[0061] Referring to Figure 1 and Figure 4 According to some embodiments of the present application, the controller 500 and the alarm 600 are further included, and the controller 500 is electrically connected with the sensor and the alarm 600, respectively.

[0062] It can be understood that the sensor can feed back the sensed signal to the controller 500, and if the sensor senses that the detection part 200 has passed through the gap 120, it indicates that the installation of the power connection end 710 of the workpiece 700 to be detected is abnormal, and the controller 500 can control the alarm 600 to issue an alarm to notify the staff.

[0063] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
