Description

Technical Field

[0001] This application belongs to the field of detection technology, and particularly relates to a depth detection device. Background Art

[0002] During the production process of connectors, when detecting connectors, it is usually necessary to detect the distance between the front end of the connector terminal and the end face of the connector insertion port, so as to determine whether the depth of the connector terminal is qualified.

[0003] For example Figure 1 As shown in the connector 101, when detecting, it is necessary to detect the distance between the front end 1011a of the terminal 1011 of the connector 101 and the end face 1012a of the insertion port 1012 of the connector 101, so as to determine whether the depth of the terminal 1011 from the insertion port 1012 is qualified.

[0004] The existing detection devices generally detect through a structure of a probe plus a sensor. The probe is used to contact the terminal, and the moving distance of the probe is detected by the sensor, so as to detect the depth of the terminal. The volume of this detection structure is relatively large, and since the distance between the terminals of the connector is relatively close, it is impossible to simultaneously detect multiple terminals of the connector through multiple probes. Only one terminal can be detected at a time. In the case of a large number of terminals, many detection stations need to be set up, resulting in a large volume and high cost of the detection device. Summary of the Utility Model

[0005] The purpose of this application is to provide a depth detection device to solve the deficiencies of the prior art.

[0006] To achieve the above purpose, this application provides the following technical solutions:

[0007] A depth detection device includes.

[0008] Probe module, which includes a mounting base, a reference post, an elastic member and a probe. The mounting base has a first end face and a second end face disposed at both ends of the mounting base along a first direction. The first end face is used to abut against the reference face of the device to be detected during detection. The reference post, the elastic member and the probe are all disposed on the mounting base. The reference post protrudes from the second end face and serves as a judgment reference for judging whether the depth of the to-be-detected surface of the device to be detected is qualified. The probe is slidably disposed on the mounting base along the first direction and has a first end and a second end opposite to each other along the first direction. The elastic member is configured to push the first end out to protrude from the first end face, and the distance that the first end protrudes from the first end face is greater than the depth of the to-be-detected surface. The second end extends out from the second end face. During detection, the first end is used to abut against the to-be-detected surface, and the to-be-detected surface pushes the probe towards the second end. Whether the depth of the to-be-detected surface is qualified is judged by comparing the distance between the second end and the end face of the reference post.

[0009] Drive module, connected to the probe module and used to drive the probe module to move along the first direction;

[0010] Camera module, disposed on one side of the probe module along a second direction perpendicular to the first direction and used to photograph the distance between the second end and the end face of the reference post;

[0011] Fixture module, disposed on one side of the probe module along the first direction close to the first end and used to fix the device to be detected.

[0012] In some embodiments, the mounting base includes a mounting portion, a fixing portion and a detecting portion. The fixing portion is disposed on the side of the mounting portion away from the camera along the second direction. The fixing portion is used to connect the drive module. The detecting portion is disposed on the side of the mounting portion close to the fixture module along the first direction. The cross-sectional dimension of the detecting portion is smaller than that of the fixing portion, so that the detecting portion can extend into the device to be detected. The first end face is disposed at one end of the detecting portion close to the fixture module. The first end of the probe extends out from the first end face. The second end face is disposed at the end of the mounting portion away from the fixture module.

[0013] In some embodiments, the probe is provided with an abutting surface located inside the mounting base and facing the second end face. An end plate is provided on the second end face. One end of the elastic member abuts against the end plate, and the other end abuts against the abutting surface.

[0014] In some embodiments, there are multiple probes, and the multiple probes are arranged in sequence along the third direction. The probe includes a bent portion located between the first end and the second end. The bent portions of some of the probes are bent upward along the second direction, and the bent portions of some of the probes are bent downward along the second direction. Moreover, the second ends of the probes are at the same height in the second direction, so as to convert the depth of the to-be-detected surfaces at different heights of the to-be-detected device in the second direction to the second ends of the probes at the same height for detection.

[0015] In some embodiments, the reference post and the second end are at the same height in the third direction.

[0016] In some embodiments, a contact plate is provided at the first end of the probe. The contact plate is used to contact the to-be-detected surface, and the contact plates on adjacent probes extend in opposite directions along the third direction.

[0017] In some embodiments, the probe module further includes:

[0018] A guiding pin, which is disposed on the mounting base along the third direction. A strip-shaped hole is provided on the probe, and the strip-shaped hole extends along the first direction. The guiding pin passes through the strip-shaped hole to guide the sliding of the probe along the first direction; the third direction is perpendicular to the first direction and the second direction pairwise.

[0019] In some embodiments, the driving module includes a cylinder. The cylinder block of the cylinder is connected to the machine platform of the depth detection device, and the slide of the cylinder is connected to the mounting base.

[0020] In some embodiments, the fixture module includes a bottom plate and limit blocks provided at both ends of the bottom plate along the first direction. The limit blocks are used to fix both ends of the to-be-detected device along the first direction. The bottom plate is provided with a first positioning hole for cooperating with the positioning post of the to-be-detected device, and a second positioning hole for cooperating with the terminals of the to-be-detected device.

[0021] In some embodiments, the camera module includes:

[0022] A column, which is disposed on the machine platform of the depth detection device;

[0023] A camera, which is disposed on the column;

[0024] A light source, which is disposed on the column and below the camera.

[0025] The advantages of the present application are as follows: The probe module transfers the depth of the surface to be detected of the device to be detected to the second end (rear end) of the probe. During detection, the first end face of the mounting base contacts the reference face of the device to be detected, the front end of the probe contacts the surface to be detected, and the probe is elastically abutted against the surface to be detected under the elastic force of the elastic member. After contact, it is pushed backward by the surface to be detected. If the probe is pushed until the second end face is flush with the end face of the reference post, it indicates that the depth of the side to be detected is the standard value. If the second end face of the probe is before or after the end face of the reference post, it indicates that the depth of the surface to be detected is too deep or too shallow. During determination, the distance between the second end of the probe and the reference post is photographed. When the distance between the second end of the probe and the end face of the reference post is within a predetermined range, the depth is determined to be qualified. The above detection method transfers the depth dimension that cannot be seen visually to the second end of the probe, so that it can be determined by photographing with a camera, without the need to determine by a sensor. The structure is simple and the cost is low. When there are more surfaces to be detected, only the number of probes needs to be increased correspondingly, and multiple depth values of small products can be detected simultaneously, without the need to set up multiple stations to detect each depth value separately. The detection device has a small volume and a low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0055] The embodiment of the present application provides a depth detection device. As Figure 3 and Figure 4 shown, the depth detection device 10 includes a probe module 100, a driving module 200, a camera module 300, and a fixture module 400. The probe module 100 is used to detect the device to be detected. The driving module 200 is used to drive the probe module 100 to reciprocate in the first direction, so that the probe module 100 cooperates with the device to be detected or separates from the device to be detected, facilitating the loading and unloading of the device to be detected. The camera module 300 is used to take pictures of the detection results of the probe module 100, so as to judge whether the depth of the surface to be detected of the device to be detected is qualified. The fixture module 400 is used to fix the device to be detected. For ease of description, it is defined that the first direction, the second direction, and the third direction respectively correspond to Figure 3 the X direction, the Z direction, and the Y direction of the spatial coordinate system shown, which can also be said to be the front-back direction, the up-down direction, and the left-right direction.

[0056] In the embodiment of the present application, the device to be detected is Figure 1 and Figure 2 the connector 101 shown. The surface to be detected is the end face 1011a of the terminal 1011 of the connector 101. The depth detection device 10 is used to detect whether the distance between the end face 1011a of the terminal 1011 and the end face 1012a of the insertion port 1012 is qualified, that is, to detect whether the depth of the terminal 1011 is qualified. In other alternative embodiments, the depth detection device 10 of the embodiment of the present application can also be applied to other types of devices to be detected, not limited to being applied to connectors. For ease of introduction, in the embodiment of the present application, the Figure 1 shown connector 101 is used as the detection object to specifically introduce the structure and detection principle of the depth detection device 10 of the embodiment of the present application.

[0057] Combined with Figure 5 , Figure 6 and Figure 7As shown, the probe module 100 includes a mounting base 110, a reference post 120, an elastic member 130, and a probe 140. The mounting base 110 has a first end face 1101 and a second end face 1102 disposed at both ends of the mounting base 110 along the first direction (X direction). The first end face 1101 is used to abut against the reference face of the device to be detected during detection. In Figure 1 the shown device to be detected, the connector 101, the reference face is the end face 1012a of the insertion interface 1012. As Figure 11 shown, when detecting the connector 101, the first end face 1101 of the mounting base 110 abuts against the reference face 1012a of the connector 101.

[0058] As Figure 6 shown, the reference post 120, the elastic member 130, and the probe 140 are all disposed on the mounting base 110. The reference post 120 protrudes from the second end face 1102. The reference post 120 serves as a judgment reference for determining whether the depth of the surface to be detected of the device to be detected 101 is qualified, and specific details will be introduced later. As Figure 5 and Figure 6 shown, the probe 140 is disposed along the first direction (X direction). The probe 140 has a first end 141 and a second end 142 opposite to each other along the first direction (X direction). The probe 140 can slide on the mounting base 110 along the first direction (X direction). The elastic member 130 is configured to push the first end 141 out to protrude from the first end face 1101, and the distance that the first end 141 protrudes from the first end face 1101 is greater than the depth of the surface to be detected, so that the first end 141 of the probe 140 can be tightly pressed against the surface to be detected, thereby accurately detecting the depth of the surface to be detected. The surface to be detected is Figure 1 the front end 1011a of the terminal 1011 of the shown connector 101. As Figure 5 shown, the second end 142 of the probe 140 extends out from the second end face 1102 of the mounting base 110, so that the depth of the side surface 1011a can be observed at the second end 142 of the probe 140.

[0059] Combined with Figure 1 and Figure 10As shown in the figure, during detection, the first end face 1101 of the probe module 100 mounting base 110 abuts against the reference face 1012a of the connector 101 for positioning. After the first end 141 of the probe 140 of the probe module 100 abuts against the surface 1011a to be measured of the connector 101, the probe 140 will be pushed by the surface 1011a to be measured towards the second end 142, that is, pushed backward. In the embodiment of the present application, the distance that the first end 141 of the probe 140 protrudes from the first end face 1101 of the mounting base 110 is greater than the depth of the surface 1011a to be measured, which can ensure that the first end 141 of the probe 140 has sufficient length to cover the depth of the surface 1011a to be measured, ensure the contact between the probe 140 and the surface 1011a to be measured, and thus ensure the effectiveness of the detection. The function of the elastic member 130 is to enable the probe 140 to always be in contact with the surface 1011a to be measured, and at the same time ensure that the probe 140 has a retraction space and can be pushed backward by the surface 1011a to be measured, so as to always reflect the true depth of the surface 1011a to be measured.

[0060] The standard for judging whether the depth of the surface 1011a to be measured is qualified is as follows: If the distance between the second end 142 of the probe 140 and the end face 1201 of the reference post 120 after the probe 140 is pushed backward is within a certain range, it is qualified; if the distance between the second end 142 of the probe 140 and the end face 1201 of the reference post 120 after the probe 140 is pushed backward exceeds a certain range, it is unqualified. That is to say, the depth of the surface to be measured is judged by comparing the relative position between the second end 142 and the reference post 120. Specifically, the second end of the probe 140 can be photographed by the camera module 300, and then the system judges the photographed photo to determine whether the depth is qualified.

[0061] As Figure 4 shown, the camera module 300 is located on one side of the probe module 100 along the second direction (Z direction), specifically above the second end 142 of the probe 140 and the reference post 120, and can directly photograph the distance between the second end 142 of the probe 140 and the reference post 120, that is, photograph the relative position between the second end 142 of the probe 140 and the end face 1201 of the reference post 120.

[0062] In the embodiment of the present application, the depth dimension that cannot be directly photographed by the camera module 300 is transferred to the end of the probe 140 that can be photographed by the camera module 300, so that it can be photographed and judged by the camera 320, without setting a sensor for each depth dimension for detection, which simplifies the structure and reduces the cost. Multiple depth dimensions can be detected by one detection device, reducing the volume of the detection device and saving the detection time.

[0063] It can be understood that the reference post 120 can be fixed on the mounting base 110 or integrally formed with the mounting base 110 directly. It can also be slidably connected to the mounting base 110. When the reference post 120 is slidably connected to the mounting base 110, the reference post 120 needs to be set at a position where it can abut against the reference surface 1012a of the device to be detected 101, so as to align the reference post 120 with the reference surface of the device to be detected 101 and unify the reference.

[0064] As Figure 4 shown, the fixture module 400 is arranged on one side of the probe module 100 close to the first end 141 along the first direction (X direction), or it can be said to be arranged on the front side of the probe module 100.

[0065] In one embodiment, as Figure 5 shown, the mounting base 110 includes a mounting portion 111, a fixing portion 112 and a detecting portion 113. The mounting portion 111 is the main part of the mounting base 110. The fixing portion 112 is arranged on the side of the mounting portion 111 away from the camera 320 along the second direction (Z direction), that is, arranged on the lower side of the mounting portion 111. The fixing portion 112 is used to connect the driving module 200. Since the driving module 200 is arranged below the mounting base 110, it is convenient to mount the mounting base 110 on the driving module 200 by arranging the fixing portion 112 on the lower side of the mounting base 110. The detecting portion 113 is arranged on the side of the mounting portion 111 close to the fixture module 400 along the first direction (X direction), that is, arranged on the front side of the mounting portion 111. As Figure 5 shown, the cross-sectional dimension of the detecting portion 113 is smaller than that of the fixing portion 112, that is to say, the detecting portion 113 is smaller than the fixing portion 112, so that the detecting portion 113 can extend into the device to be detected 101. As Figure 10 shown, the smaller-sized detecting portion 113 extends into the connector 101, so as to detect the depth of the terminal 1011 in the connector 101. As Figure 5 shown, the first end face 1101 of the mounting base 110 is arranged at one end of the detecting portion 113 close to the fixture module 400, that is, arranged at the front end of the detecting portion 113. The first end 141 of the probe 140 extends out from the first end face 1101 at the front end of the detecting portion 113. The second end face 1102 of the mounting base 110 is arranged at one end of the mounting portion 111 away from the fixture module 400, that is, arranged at the rear end of the mounting portion 111. The second end 142 of the probe 140 extends out from the second end face 1102 at the rear end of the mounting portion 111.

[0066] As Figure 6 and Figure 7 shown, an abutting surface 1401 is arranged on the probe 140. As Figure 6As shown, the abutting surface 1401 is located inside the mounting seat 110. The abutting surface 1401 faces the second end surface 1102 of the probe 140, that is, faces the rear end of the probe 140, so that after the elastic member 130 abuts against the abutting surface 1401, the probe 140 can be pushed forward and toward the connector to be tested. Figure 6 As shown, an end plate 150 is disposed on the second end surface 1102 of the mounting seat 110, one end of the elastic member 130 abuts against the end plate 150, and the other end abuts against the abutting surface 1401. Figure 6 As shown, the rear end of the elastic member 130 abuts against the end plate 150 , and the front end of the elastic member 130 abuts against the abutting surface 1401 of the probe 140 .

[0067] In the embodiment of the present application, the elastic member 130 is a spring. In other optional embodiments, the elastic member 130 can also be other types of elastic members 130.

[0068] like Figure 7 As shown, there are multiple probes 140, and the multiple probes 140 are arranged in sequence along the third direction (Y direction). The number of probes 140 corresponds to the number of terminals 1011 to be detected in the connector 101, and each probe 140 is used to detect one terminal 1011. Figure 9 As shown, the probe 140 includes a bent portion 143 between the first end 141 and the second end 142. Figure 8 As shown, the bending portion 143 of some probes 140 bends upward along the second direction (Z direction), and the bending portion 143 of some probes 140 bends downward along the second direction (Z direction). The first end 141 of the probe 140 is located at different heights in the second direction (Z direction) by bending the probe 140 in different directions. Figure 11 As shown, the second end 142 of the probe 140 is located at the same height. If the first end 141 is located at different heights, terminals located at different heights can be tested. If the second end 142 is located at the same height, it is convenient to take clearer pictures and make the judgment results more accurate. The above structure can convert the depth of the test surface 1011a of the device to be tested 101 at different heights along the second direction (Z direction) to the second end 142 of the probe 140 at the same height for testing. Figure 9 and Figure 12 As shown, the first ends 141 at different heights contact the terminals 1011 at different heights, so as to achieve the conversion of the depths of the terminals 1011 at different heights to the second ends 142 at the same height for detection.

[0069] The bending direction of the bending portion 143 of the probe 140 mentioned above is different. The bending direction here refers to the position of the first end 141 relative to the second end 142 in the second direction (Z direction) after bending. Figure 9 , Figure 9The first end 141 of the middle probe 140 is located below the second end 142 in the second direction (Z direction), and is formed by bending the second end 142 downward in the second direction (Z direction). Therefore Figure 9 The bending direction of the middle probe 140 is downward bending along the second direction (Z direction). Due to the different heights of the terminals, it is necessary to set different bending directions of the probe 140 to detect terminals 1011 of different heights.

[0070] Specifically, in the embodiment of the present application, as Figure 8 shown, the bending directions of adjacent probes 140 are opposite. Adjacent probes 140 are used to detect two terminals of different heights. As Figure 8 shown, the No. ① probe 140 is bent downward, and the No. ② probe 140 is bent upward. As Figure 12 shown, the No. ① probe 140 and the No. ② probe 140 are respectively used to detect the a terminal and the b terminal, and the a terminal is lower than the b terminal. Therefore, by bending the No. ① probe 140 downward, the first end 141 of the No. ① probe 140 is lower to contact the a terminal at a lower position. By bending the No. ② probe 140 upward, the first end 141 of the No. ② probe 140 is higher to contact the b terminal at a higher position.

[0071] It can be understood that, as Figure 7 shown, the reference post 120 is at the same height as the second end 142 of the probe 140.

[0072] In the embodiment of the present application, as Figure 9 shown, a contact plate 144 is provided at the first end 141 of the probe 140. Combining Figure 9 and Figure 12 shown, the contact plate 144 is used to abut against the surface to be measured 1011a. As Figure 8 shown, the contact plates 144 on adjacent probes 140 extend in opposite directions along the third direction (Y direction). As Figure 8 shown, the contact plate 144 of the No. ① probe 140 extends to the left, and the contact plate 144 of the No. ② probe 140 extends to the right. Such a design enables adjacent probes 140 to detect terminals located at the same position in the third direction (Y direction), and by providing the contact plate 144, the contact surfaces of adjacent probes 140 are extended to the same position in the third direction (Y direction). As Figure 12 shown, the a terminal and the b terminal are located at the same position in the third direction (Y direction), only with different heights. That is, the positions of the a terminal and the b terminal coincide in the left-right direction, and the probes 140 are arranged in sequence along the Y direction, and the probes 140 are staggered in the Y direction (left-right direction). As Figure 12 shown, the No. ① probe 140 and the No. ② probe 140 are staggered in the left-right direction. As Figure 12As shown, extend the abutting plate 144 on the No. ① probe 140 to the left and extend the abutting plate 144 of the No. ② probe 140 to the right. Then, the a terminal and the b terminal that coincide in the left-right direction can be contacted by the misaligned No. ① probe 140 and No. ② probe 140.

[0073] As Figures 5 to 7 shown, the probe module 100 further includes a guide pin 160. The guide pin 160 is disposed through the mounting base 110 along the third direction (Y direction). As Figure 7 shown, a strip hole 1402 is provided on the probe 140. The strip hole 1402 extends along the first direction (X direction). The guide pin 160 passes through the strip hole 1402, thereby guiding the sliding of the probe 140 along the first direction (X direction). The length of the strip hole 1402 is much larger than the diameter of the guide pin 160, so that the probe 140 has sufficient freedom of movement in the first direction (X direction). As Figure 7 shown, there are multiple probes 140. The guide pin 160 simultaneously passes through the strip holes 1402 on multiple probes 140, so that all the probes 140 can be guided by one guide pin 160. As Figure 5 shown, the guide pin 160 is disposed through the mounting base 110, so that both ends of the guide pin 160 can be fixed on the mounting base 110.

[0074] It can be understood that, as Figure 6 shown, a channel 1103 for the probe 140 to pass through and a mounting hole 1104 for mounting the elastic member 130 are provided on the mounting base 110. In the embodiment of the present application, as Figure 6 shown, the mounting hole 1104 extends from the second end face 1102 into the interior of the mounting base 110 along the first direction (X direction). After the spring is inserted into the mounting hole 1104 and the end plate 150 is covered, the elastic member 130 can be fixed in the mounting base 110. In the embodiment of the present application, as Figure 6 shown, the projection of the mounting hole 1104 on the second end face 1102 partially overlaps with the projection of the channel 1103 on the second end face 1102, so that the colored part of the mounting hole 1104 is located in the channel 1103 and coincides with the channel 1103. When the elastic member 130 is installed in the mounting hole 1104, the elastic member 130 can abut against the probe 140.

[0075] In the embodiment of the present application, as Figure 3 shown, the driving module 200 includes a cylinder 210. The cylinder block 211 of the cylinder 210 is connected to the machine table 11 of the depth detection device 10, and the sliding table 212 of the cylinder 210 is connected to the mounting base 110 of the probe module 100, so that the movement of the sliding table 212 of the cylinder 210 drives the probe module 100 to move. As Figure 3In the state shown, the slide 212 of the cylinder 210 extends backward, driving the probe module 100 away from the fixture module 400. At this time, the fixture module 400 can be loaded; as Figure 4 In the state shown, the connector 101 has been placed on the fixture module 400. The slide 212 of the cylinder 210 retracts, driving the probe module 100 closer to the fixture module 400. The probe 140 of the probe module 100 contacts the connector 101 for detection.

[0076] As Figure 13 shown, the fixture module 400 includes a bottom plate 410, a vertical plate 420, and limit blocks 430 provided at both ends of the bottom plate 410 along the first direction (X direction). The bottom plate 410 is installed on the machine table of the depth detection device 10 through the vertical plate 420. Combining Figure 4 and Figure 13 , the limit blocks 430 are used to fix both ends of the connector 101 to be detected along the first direction (X direction), that is, the front and rear ends. As Figure 2 shown, a positioning post 1013 is provided at the bottom of the connector 101, and the welding end 1011b of the terminal also extends from the bottom of the connector 101. The positioning post 1013 is used for positioning when the connector 101 is welded to the circuit board, and the welding end 1011b of the terminal 1011 is welded to the circuit board. Therefore, when detecting the depth, the positioning post 1013 and the welding end 1011b of the terminal 1011 of the connector 101 can be used to position the connector 101. As Figure 13 shown, a first positioning hole 411 and a second positioning hole 412 are provided on the bottom plate 410 of the fixture module 400. The first positioning hole 411 is used to cooperate with the positioning post 1013 of the connector 101 to be detected, and the second positioning hole 412 is used to cooperate with the welding end 1011b of the terminal 1011 of the device 101 to be detected.

[0077] As Figure 3 shown, the camera module 300 includes a column 310, a camera 320, and a light source 330. The column 310 is provided on the machine table of the depth detection device 10. The camera 320 is provided on the column 310, and the camera 320 is installed on the machine table through the column 310. The light source 330 is provided on the column 310 and is located below the camera 320, and is used to supplement light when the camera 320 takes pictures to make the shooting clearer.
