[0035] Referring to Figures 1 to 7 The embodiment of the present application discloses a patch inductor tin paste determination device, which comprises a rack 100 and a control module, the rack 100 is provided with a mold assembly 200 which can slide in a first direction, the mold assembly 200 can support a plurality of patch inductors 300, and the rack 100 is further provided with a CCD camera 400, a waste tray 500 and a blanking assembly 600 in sequence along the first direction.

[0036] The CCD camera 400 is used to acquire image information of the patch inductor 300 below the CCD camera 400, when the mold assembly 200 slides along the first direction, the plurality of patch inductors 300 on the mold assembly 200 can pass below the CCD camera 400 in turn, the CCD camera 400 is electrically connected with the control module, the CCD camera 400 can send the image information to the control module, the waste tray 500 is used to support the unqualified patch inductor 300, the blanking assembly 600 can slide along the first direction relative to the rack 100, the blanking assembly 600 is provided with a plurality of first suction members 610, the plurality of first suction members 610 can correspondingly adsorb the plurality of patch inductors 300 on the mold assembly 200, the blanking assembly 600 is electrically connected with the control module, the control module can control the first suction member 610 corresponding to the unqualified patch inductor 300 to release the patch inductor 300 when the blanking assembly 600 slides to above the waste tray 500 according to the image information, and the rack 100 is provided with a blanking material tray 110 below the blanking assembly 600, and the blanking material tray 110 is used to support the qualified patch inductor 300 transferred by the blanking assembly 600.

[0037] It can be understood that when it is needed to determine whether the tin paste coating area 310 on the plurality of patch inductors 300 is qualified, the plurality of patch inductors 300 can be first placed on the mold assembly 200, when the mold assembly 200 supports the plurality of patch inductors 300 and slides along the first direction, the plurality of patch inductors 300 on the mold assembly 200 can pass below the CCD camera 400 in turn, the CCD camera 400 can acquire the image information of the patch inductor 300 below and send the image information to the control system, then the control system can determine whether the tin paste coating area 310 on the patch inductor 300 is unqualified according to the above image information, when the patch inductor 300 is unqualified, the control system can control the corresponding first suction member 610 on the blanking assembly 600 to release the unqualified patch inductor 300 when the first suction member 610 moves to above the waste tray 500, the unqualified patch inductor 300 falls into the waste tray 500 to wait for recycling, and the remaining qualified patch inductor 300 is transferred by the blanking assembly 600 and placed on the blanking material tray 110. The present application can automatically determine whether the tin paste coating area 310 on the patch inductor 300 is qualified, can save labor cost, and improve determination efficiency and accuracy.

[0038] It should be noted that the CCD camera has strong scanning function, good image definition, and can capture images at any time. The CCD camera is a commonly used device in the processing, manufacturing and testing process in the field, and its specific structure and principle are common knowledge in the field, which will not be described here.

[0039] In addition, the first suction accessory 610 described above can be a suction disc connected to a negative pressure source. When the first suction accessory 610 adsorbs the unqualified patch inductor 300, the control module can cut off the communication between the corresponding first suction accessory 610 and the negative pressure source.

[0040] As shown in Figures 1 to 3 The rack 100 is further provided with a feeding tray 120 and a feeding assembly 700. The feeding tray 120 is used to support a plurality of patch inductors 300. The feeding assembly 700 can slide relative to the rack 100 along a first direction. The feeding assembly 700 can suck the plurality of patch inductors 300 in the feeding tray 120 and transfer the plurality of patch inductors 300 to the mold assembly 200. By providing the feeding assembly 700, the continuous supply of patch inductors 300 to the mold assembly 200 can be realized, and the continuous automatic determination of a large number of patch inductors 300 can be realized.

[0041] It can be understood that the number of patch inductors 300 that the mold assembly 200 in the embodiment of the present application can support is equal to the number of patch inductors 300 that the feeding tray 120 can support. The number of patch inductors 300 that the unloading tray 110 can support in the first direction is an integer multiple of the number of patch inductors 300 that the mold assembly 200 can support. For example, when the mold assembly 200 can support ten patch inductors 300, the feeding tray 120 can also support ten patch inductors 300. At this time, the feeding assembly 700 can transfer ten patch inductors 300 from the feeding tray 120 to the mold assembly 200. Correspondingly, the number of patch inductors 300 that the unloading tray 110 can support in the first direction can be twenty, that is, the unloading assembly 600 needs to transfer the patch inductors 300 on the mold assembly 200 twice to fill a row of material placement positions of the unloading tray 110 in the first direction. It should be noted that the unloading assembly 600 needs to be staggered by a certain distance between each time it is transferred to the position of the unloading tray 110. The above distance is the distance between adjacent patch inductors 300 in the unloading tray 110. Specifically, the number of patch inductors 300 that the unloading tray 110 can support in the first direction is designed to be an integer multiple of the number of patch inductors 300 that the mold assembly 200 can support. This can make the patch inductors 300 in the unloading tray 110 more closely arranged, saving space. Designing the number of patch inductors 300 that the mold assembly 200 can support to be equal to the number of patch inductors 300 that the feeding tray 120 can support can make the adjacent patch inductors 300 on the mold assembly 200 have a proper distance, preventing the CCD camera from being unable to identify due to the proximity of the patch inductors 300.

[0042] Referring to Figure 3 and Figure 4The feeding assembly 700 in the embodiment of the present application comprises a sliding block 710, a support 720 and a plurality of second suction accessories 730. The sliding block 710 is arranged on the rack 100 and slides in the first direction. The support 720 is arranged on the sliding block 710 and can slide in the vertical direction. The second suction accessories 730 are arranged on the support 720 and can slide vertically relative to the support 720 between the first position and the second position. The first position is directly above the second position. The plurality of second suction accessories 730 can correspondingly suck the plurality of patch inductors 300 in the feeding position tray 120. A plurality of proximity sensors 740 are installed on the support 720. The plurality of proximity sensors 740 correspond to the plurality of second suction accessories 730 one by one. The proximity sensor 740 is used to detect whether an object is blocked within a certain distance in the horizontal direction. The proximity sensor is a commonly used sensor in the field, and its structure and working principle will not be described here. The control module is electrically connected with the plurality of proximity sensors 740 and the plurality of second suction accessories 730. The feeding position tray 120 is arranged with a plurality of accommodation grooves for respectively accommodating the plurality of patch inductors 300. When the second suction accessory 730 is located at the second position, the proximity sensor 740 is not blocked by the second suction accessory 730. When the support 720 moves downward and the lower end of the second suction accessory 730 is attached to the top surface of the patch inductor 300, the support 720 can continue to move downward by a preset distance to make the second suction accessory 730 located at the first position. At this time, the top of the second suction accessory 730 blocks the proximity sensor 740. The preset distance is less than the groove depth of the accommodation groove.

[0043] Specifically, when some of the accommodation grooves in the feeding position tray 120 lack patch inductors 300, after the support 720 moves downward and the lower end of the second suction accessory 730 is attached to the top surface of the patch inductor 300, if the support 720 continues to move downward by a preset distance, the second suction accessory 730 corresponding to the accommodation groove lacking the patch inductor 300 will not be stopped by the patch inductor 300. The lower end of the second suction accessory 730 will extend into the accommodation groove. Therefore, this part of the second suction accessory 730 is still located at the second position, and the top of the second suction accessory 730 located at the second position will not block the proximity sensor 740. Conversely, the second suction accessory 730 corresponding to the accommodation groove containing the patch inductor 300 will be lifted upward relative to the support 720 to the first position due to the upward stopping force of the patch inductor 300. At this time, the top of the second suction accessory 730 at the first position will block the proximity sensor 740. By arranging the proximity sensor 740 and the second suction accessory 730 that can slide, the feeding assembly 700 can determine whether there is no patch inductor 300 placed in the accommodation groove, thereby preventing the patch inductor 300 from being missed on the feeding position tray 120.

[0044] The second suction accessory 730 can be a suction cup connected with a negative pressure source. It should be noted that if the patch inductor 300 is missed in the feeding position 120, the second suction accessory 730 at the position where the patch inductor 300 is missed will produce air leakage when the feeding assembly 700 moves the patch inductor 300, which will easily cause the suction force of other second suction accessories 730 to weaken, thereby causing the patch inductor 300 to fall off during the movement of the feeding assembly 700.

[0045] It can be understood that the second suction accessory 730 in the embodiment of the present application is provided between the support 720 and the second suction accessory 730, and a compression elastic member (not shown in the figure) is arranged at both ends of the compression elastic member, and the two ends of the compression elastic member are connected with the second suction accessory 730 and the support 720, respectively. The compression elastic member can assist the second suction accessory 730 to move downward to the second position. Of course, in the embodiment without the compression elastic member, the second suction accessory 730 can also return to the second position by gravity.

[0046] Referring to Figure 6 and Figure 7 The mold assembly 200 includes a base plate 210 and a first clamping plate 220 and a second clamping plate 230, and the first clamping plate 220 and the second clamping plate 230 are both slidingly arranged on the base plate 210, and the first clamping plate 220 and the second clamping plate 230 can clamp and fix the patch inductor 300 on the base plate 210. In the embodiment without the first clamping plate 220 and the second clamping plate 230, the patch inductor 300 only needs to be placed in the plurality of feeding positions 211 on the mold assembly 200. However, in order to make the position of the patch inductor 300 on the base plate 210 more accurate, so that the CCD camera 400 can acquire image information more quickly and accurately, the first clamping plate 220 and the second clamping plate 230 can be arranged, and when the patch inductor 300 is placed on the base plate 210, the first clamping plate 220 and the second clamping plate 230 can slide a certain distance and clamp the patch inductor 300, thereby realizing the positioning of the patch inductor 300.

[0047] Referring to Figure 6 and Figure 7The substrate 210 is provided with a plurality of storage positions 211, and a limiting protrusion 222 is arranged at each storage position 211 of the substrate 210 and can resist one side of the chip inductor 300 in the first direction. The first clamping plate 220 is provided with a plurality of first abutting blocks 221 corresponding to the plurality of storage positions 211, and the first clamping plate 220 can slide in the first direction to clamp the chip inductor 300 between the first abutting block 221 and the limiting protrusion 222 in the first direction, that is, the first clamping plate 220 can clamp the chip inductor 300 from the first direction. It can be understood that the sliding of the first clamping plate 220 can drive the plurality of first abutting blocks 221 on the first clamping plate 220 to slide synchronously in the first direction, so that the synchronous positioning of the plurality of chip inductors 300 in the first direction can be realized. In addition, the second clamping plate 230 is provided with a plurality of second abutting blocks 231 corresponding to the plurality of storage positions 211, and the second clamping plate 230 can slide in the horizontal plane in the second direction perpendicular to the first direction. The second clamping plate 230 can clamp the chip inductor 300 between the second abutting block 231 and the limiting protrusion 222 in the second direction, that is, the second clamping plate 230 can clamp the chip inductor 300 from the second direction. It can be understood that the sliding of the second clamping plate 230 can drive the plurality of second abutting blocks 231 on the second clamping plate 230 to slide synchronously in the second direction, so that the synchronous positioning of the plurality of chip inductors 300 in the second direction can be realized. It should be noted that the sliding of the first clamping plate 220 and the second clamping plate 230 can be driven by the air cylinder.

[0048] As shown in Figure 6 and Figure 7 The limiting protrusion 222 has a first limiting surface 223 and a second limiting surface 224, and the included angle between the first limiting surface 223 and the second limiting surface 224 is 90°, that is, the first limiting surface 223 and the second limiting surface 224 form a 90° corner on the limiting protrusion 222. The first clamping plate 220 can clamp the chip inductor 300 between the first abutting block 221 and the first limiting surface 223, and the second clamping plate 230 can clamp the chip inductor 300 between the second abutting block 231 and the second limiting surface 224.

[0049] The technical features of the above-mentioned embodiments can be combined in any manner. In order to make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0050] Of course, the present application is not limited to the above-mentioned embodiments, and those skilled in the art can make equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
