[0028] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this utility model belongs. The terms used in this specification and in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the relevant listed items.

[0029] See also Figure 1 and Figure 2 The detection fixture 1000 includes a detection mechanism 1, a base 2 and a locking mechanism 3. The detection mechanism 1 is used to accommodate and detect materials, which include but are not limited to circuit boards, electronic components, etc.; the base 2 is used to hold the detection mechanism 1, and the base 2 should ensure a certain degree of flatness to ensure the stability of the detection mechanism 1 and facilitate the installation and debugging of the detection mechanism 1, and some components of the detection mechanism 1 can be moved relative to the base 2 to complete automated detection; the locking mechanism 3 is provided on the detection mechanism 1, and is used to lock the detection mechanism 1 to the base 2. The locking mechanism 3 makes the detection mechanism 1 detachably installed on the base 2, so that the detection fixture 1000 can be quickly disassembled when there is a need for upgrading, modification or maintenance and disassembly, thereby further improving the utilization rate of each part of the detection fixture 1000.

[0030] It can be understood that the detection fixture 1000 can also be provided with a picking mechanism (not shown in the figure), which is used in conjunction with the detection mechanism 1, so that the detection fixture 1000 can achieve a fully automated detection process without any manual labor. Specifically, the picking mechanism includes a universal motion component, a picking component and a sensing component, wherein the universal motion component can achieve 360-degree rotation around the base 2 so that the picking mechanism can pick up corresponding materials from all directions. The picking component is used to pick up materials, and the sensing component is used to detect whether the material is pickable when the picking component performs a picking operation, so as to avoid the picking component being unable to pick up the corresponding material.

[0031] It is worth noting that the locking mechanism 3 includes but is not limited to snaps, mortise and tenon joints, and bolts, etc., as long as the detection mechanism 1 is detachably mounted on the base 2. In this embodiment, preferably, the locking mechanism 3 is selected as a bolt.

[0032] Specifically, for the above-mentioned locking mechanism 3, please refer to Figure 1 The locking mechanism 3 includes at least four bolts; the at least four bolts are used to lock the detection mechanism 1 to the base 2.

[0033] For the above mentioned testing agency 1, please refer to Figure 1 The detection mechanism 1 includes a lower mold wire box 11, an upper detection module 12 and a lower detection module 13, wherein the upper detection module 12 and the lower detection module 13 are arranged relative to each other, and the upper detection module 12 can move in a direction vertically close to the lower detection module 13. The upper detection module 12 and the lower detection module 13 are used to perform upper and lower double-sided detection on the material. The lower detection module 13 is accommodated in the lower mold wire box 11, and the lower mold wire box 11 includes at least four through holes (not marked), and the at least four through holes are evenly distributed at the four corners of the lower mold wire box 11.

[0034] It can be understood that in some embodiments, only single-sided inspection of the material is required, so only an upper inspection module 12 is provided to detect various components installed on the top surface of the material, thereby eliminating the need for a lower inspection module 13, further reducing the volume of the inspection fixture 1000 and improving the integration of the inspection fixture 1000.

[0035] In some embodiments, see Figure 3 The lower mold line box 11 also includes a switch 111, a data transmission interface 112, and a power interface (not shown). The power interface is used to connect to an external power source to provide power to the detection mechanism 1. The switch 111 is electrically connected to the power interface to control the connection and disconnection between the detection mechanism 1 and the power source. The data transmission interface 112 serves as the data transmission and aggregation terminal of the detection mechanism 1. The detection data of the detection fixture 1000 is transmitted and aggregated to an external control and display device through this port, making the detection data more intuitive and easier to collect.

[0036] It can be understood that the data transmission interface 112 includes but is not limited to a 64-pin header, an RJ45 interface, a serial interface, an SPI interface, and a UART interface, etc. Users can select a suitable interface according to actual needs. This embodiment will not provide examples for each interface one by one.

[0037] It can be understood that in order to cooperate with the bolts, the base 2 is correspondingly provided with at least four screw holes (not shown), wherein a bolt passes through a through hole and is screwed into a screw hole.

[0038] In some embodiments, see Figures 4 to 6The detection mechanism 1 includes an upper detection module 12 and a lower detection module 13, the upper detection module 12 includes a pressure plate 121 and an upper detection component 122, and the upper detection component 122 is arranged on the pressure plate 121; and / or, the lower detection module 13 includes a download plate 131 and a lower detection component 132, the lower detection component 132 is arranged on the bottom surface of the download plate 131, and the top surface of the download plate 131 is provided with a receiving groove 1311, which is used to receive materials.

[0039] It can be understood that the receiving groove 1311 is widened to a certain extent relative to the material so as to form a material picking area (not marked) in the receiving groove 1311. The material picking area is convenient for human hands or picking components to pick up and place materials, thereby avoiding the contact of human hands or picking components with the lower detection component 132 to a certain extent, thereby protecting the detection fixture 1000.

[0040] In some embodiments, see Figure 5 The lower detection module 13 also includes at least four positioning blocks 133, which are screwed onto the download plate 131 according to preset dimensions. The positioning blocks 133 are used to limit the material on all sides to prevent the material from moving on the download plate 131, and the positioning blocks 133 can also be used in conjunction with the receiving slot 1311.

[0041] It is understandable that in order to ensure accurate positioning of the material, positioning blocks 133 are additionally provided in the middle of the four sides of the material, thereby achieving complete positioning of the material in the horizontal direction.

[0042] For the above detection module 12, please refer to Figure 4 The upper detection module 12 also includes a top plate 123, a detection camera 124 and at least four guide pillars 125. The top plate 123 is arranged opposite to the pressure plate 121. The top plate 123 is used to protect the detection camera 124 and provide certain support. One end of at least four guide pillars 125 is plugged and fixed to the top plate 123, and the other end of at least four guide pillars 125 is plugged and fixed to the pressure plate 121. The top plate 123, the pressure plate 121 and the guide pillars 125 enclose a limited space. The detection camera 124 is accommodated in the limited space, and the detection camera 124 can move with the limited space, wherein the detection camera 124 is used to take pictures and / or real-time video of the material.

[0043] It can be understood that the top plate 123 and the pressure plate 121 are detachably connected through the guide column 125. The connection method includes but is not limited to: interference fit, screw connection, clamping, etc. For example, the guide column 125 is provided with a thread, and the top plate 123 and the pressure plate 121 are provided with corresponding screw holes to achieve screw fixation, and the user can adjust the length of the guide column 125 according to actual needs so that the size of the limit space can be adjusted as needed, which is convenient for the subsequent upgrade, modification or repair and replacement of the detection camera 124.

[0044] It is understood that in some embodiments, see Figure 4 and Figure 5 The pressing plate 121 includes at least four alignment posts 1211, and at least four alignment posts 1211 are arranged on the same side of the pressing plate 121; the downloading plate 131 includes at least four alignment holes 1315, and at least four alignment holes 1315 correspond to at least four alignment posts 1211. The alignment holes 1315 are used to guide the movement direction of the alignment posts 1211. The pressing plate 121 relies on the cooperation between the alignment posts 1211 and the downloading plate 131 to achieve precise alignment between the pressing plate 121 and the downloading plate 131, thereby ensuring the accuracy of the upper detection module 12 when detecting the material, and avoiding the occurrence of inaccurate detection alignment.

[0045] In some embodiments, see Figure 4 The pressure plate 121 also includes at least four limit blocks 1212, which are evenly distributed at the four diagonal corners of the pressure plate 121, and the limit blocks 1212 are arranged adjacent to the alignment columns 1211. The limit blocks 1212 are used to limit the movement distance of the upper detection module 12 in the direction close to the lower detection module 13, to prevent the upper detection module 12 from moving more than a preset distance, causing the upper detection component 122 to collide with the lower detection component 132, thereby causing damage to the upper detection component 122.

[0046] For the above-mentioned upper detection component 122, please refer to Figure 4 The upper detection component 122 includes an upper mold needle block 1221, a plurality of upper probes 1222, an upper mold adapter block 1223 and an adapter needle 1224. The plurality of upper probes 1222 are arranged on the upper mold needle block 1221. The upper probes 1222 are used to detect materials. The upper mold adapter block 1223 is electrically connected to the plurality of upper probes 1222. The upper mold adapter block 1223 is used to transmit the detection data of the plurality of upper probes 1222 and the upper mold adapter needle 1224. The adapter needle 1224 is fixed to the upper mold needle block 1221. The adapter needle 1224 is used to detect and feedback the movement state of the upper detection component 122 in the direction vertically approaching the lower detection module 13, and the detection data of the adapter needle 1224 can also be transmitted through the upper mold adapter block 1223. The upper mold adapter block 1223 transmits the detection data to the external device through the data transmission interface 112 so that the external device can perform analysis and processing.

[0047] It is worth noting that the upper mold needle block 1221 is provided with a plurality of receiving holes (not shown), and the plurality of upper probes 1222 are correspondingly received in the plurality of receiving holes. The arrangement of the upper probes 1222 within the receiving holes needs to be set according to the actual locations of the material to be inspected, so that when inspecting the material, a single inspection operation can be performed to complete all inspections of the material. Different materials correspond to different upper probe 1222 layouts, and the specific layout can be set according to actual needs, and this embodiment will not be further illustrated.

[0048] The working process of the above-mentioned adapter needle 1224 is as follows: the adapter needle 1224 moves with the pressure plate 121. When the adapter needle 1224 contacts the material, the adapter needle 1224 feeds back an electrical signal to the detection mechanism 1. After receiving the feedback electrical signal from the adapter needle 1224, the detection mechanism 1 performs subsequent detection operations. It can be understood that the above-mentioned adapter needle 1224 can be replaced with a distance sensor, an infrared sensing sensor, etc., to realize the detection and feedback of the state of the detection mechanism 1.

[0049] In some embodiments, see Figure 4 The upper detection component 122 also includes at least four pressure rods 1225, which are symmetrically arranged on both sides of the upper mold needle block 1221. The pressure rods 1225 are used to abut the material when the upper detection component 122 moves in a direction vertically close to the lower detection module 13 to prevent the material from being displaced by external force, such as the movement of the material caused by the vibration that may be caused by the detection fixture 1000 in the working state, thereby improving the detection accuracy of the upper detection component.

[0050] For the lower detection assembly 132, see Figure 5 and Figure 6 The lower detection component 132 includes a lower mold needle block 1321, several lower probes 1322 and a lower mold adapter block 1323. The several lower probes 1322 are arranged on the lower mold needle block 1321. The lower probes 1322 are used to detect materials. The lower mold adapter block 1323 is electrically connected to the several lower probes 1322. The lower mold adapter block 1323 is used to transmit the detection data of the several lower probes 1322. The lower mold adapter block 1323 is also electrically connected to the data transmission interface 112, so that the detection data can be communicated with external equipment through the data transmission interface 112.

[0051] It is worth noting that the lower detection module 13 is housed in the lower mold wire box 11, that is, the download plate 131 and the lower detection assembly 132 are both housed in the lower mold wire box 11, wherein the top of the lower mold wire box 11 is provided with an opening (not marked), for the lower detection module 13 to be placed in the lower mold wire box 11 from the opening, and in order to provide a certain accommodation space for the lower detection module 13, the lower detection module 13 also includes at least six support columns 134, one end of the support column 134 is fixed to the download plate 131, and the support column 134 is provided with a plurality of support columns 134. The other end is fixed to the bottom of the lower mold wire box 11, and the support columns 134 are symmetrically arranged between the download plate 131 and the bottom of the lower mold wire box 11. When the download plate 131 covers the above-mentioned opening, the edge of the download plate 131 abuts the periphery of the lower mold wire box 11. At least six support columns 134 jointly support the middle area of the download plate 131, thereby improving the load-bearing capacity of the download plate 131, and providing a certain degree of protection for the lower detection component 132, thereby improving the structural stability of the lower detection module 13.

[0052] It is worth noting that in order to enable the lower detection component 132 to detect the bottom surface of the material, the download plate 131 is provided with corresponding detection holes so that the lower probes 1322 of the lower detection component 132 can pass through the detection holes to detect the material.

[0053] In some embodiments, see Figure 5 The download plate 131 includes a first plate body 1312, a second plate body 1313 and at least four height adjustment screws 1314. The first plate body 1312 is provided with at least four first height adjustment holes (not marked). One end of the at least four height adjustment screws 1314 is screwed into the first height adjustment hole and then passes through the first height adjustment hole and abuts the second plate body 1313. By adjusting the screwing amount of the four height adjustment screws 1314, a certain angle of inclination can be achieved between the first plate body 1312 and the second plate body 1313, so that the download plate 131 can still remain level when the external bottom surface environment is in an inclined state, thereby improving the applicability of the detection fixture 1000 and avoiding the detection fixture 1000 from being unusable due to uneven external environment.

[0054] In an embodiment of the present invention, the detection fixture 1000 includes a detection mechanism 1, a base 2, and a locking mechanism 3. The detection mechanism 1 is used to accommodate and detect materials, and the base 2 is used to hold the detection mechanism 1. The base 2 should ensure a certain degree of flatness to ensure the stability of the detection mechanism 1 and facilitate the installation and debugging of the detection mechanism 1. Some components of the detection mechanism 1 can be moved relative to the base 2 to complete automated testing. The locking mechanism 3 is provided on the detection mechanism 1 and is used to lock the detection mechanism 1 to the base 2. Through the above structure, the embodiment of the present invention can make the detection mechanism 1 detachably installed on the base 2 through the locking mechanism 3, thereby making it possible to quickly disassemble the detection mechanism 1 when the detection fixture 1000 needs to be upgraded, modified, repaired or disassembled, further improving the utilization rate of each part of the detection fixture 1000.

[0055] It should be noted that the preferred embodiments of the present invention are given in the specification and drawings of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments do not serve as additional limitations on the content of the present invention. The purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. In addition, the above-mentioned technical features continue to be combined with each other to form various embodiments not listed above, which are all considered to be within the scope of the description of the present invention; further, it is obvious to those skilled in the art that improvements or changes can be made based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present invention.
