[0008] The detection component is connected to the support base and is set corresponding to the feeder inlet.

[0009] In one embodiment, the support base includes a first mounting platform and a second mounting platform disposed opposite to each other, and a connecting portion connecting the first mounting platform and the second mounting platform; the positioning component is connected to the second mounting platform, and the detection component is connected to the first mounting platform.

[0010] In one embodiment, the positioning component has a limiting groove extending along the feeder mounting direction, and the feeder is limited in the limiting groove.

[0011] In one embodiment, the side of the second mounting platform facing the first mounting platform is recessed to form a first mounting groove; the positioning component includes a first limiting member, which is limited to the first mounting groove and has the limiting groove.

[0012] In one embodiment, the first limiting member includes a body and two protruding arms protruding from one end of the body. The limiting groove includes a first groove and a second groove communicating with the first groove. The body has the first groove, and the two protruding arms form the second groove. The width of the second groove is greater than the width of the first groove. The body is detachably limited in the first mounting groove, and the protruding arms extend out of the first mounting groove.

[0013] In one embodiment, the second mounting platform includes a latching portion that engages with the feeder. The latching portion is located at one end of the second mounting platform away from the connecting portion and is used to engage with the elastic swing arm of the feeder to limit the feeder.

[0014] In one embodiment, the positioning component includes a second limiting member detachably connected to the second mounting platform. The second limiting member protrudes from the second mounting platform and is spaced apart from the first limiting member in the feeder mounting direction. The second limiting member has a positioning hole for engaging with a positioning pin of the feeder to limit the feeder.

[0015] In one embodiment, the second limiting member is recessed on the side facing the first limiting member to form a groove, and a through hole is provided at the bottom of the groove for inserting the communication interface of the feeder; the second limiting member is provided with positioning holes at opposite ends, and the positioning holes are spaced apart from the groove.

The feeder has a feed port, and the detection component is connected to the support base and is positioned corresponding to the feeder's feed port. During feeder operation, the above feeder loading and alignment fixture can detect the position of the surface mount components supplied by the feeder's feed port through the detection component. If the position of the surface mount components is deviated, the position of the surface mount components on the conveyor belt can be adjusted by controlling the feeder's drive mechanism, ensuring that the surface mount components are consistently positioned at the feeder's feed port. This prevents pick-up failures when the pick-and-place machine's nozzles attempt to pick up surface mount components supplied by the feeder's feed port with the same positioning, thus improving the pick-and-place machine's efficiency.

In particular, the term "a" may refer to "one" in one embodiment and "more than one" in another embodiment. Therefore, the above terms should not be construed as limiting the actual number of elements of the present invention.

[0030] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0031] This utility model discloses a feeder feeding and calibration fixture 10, which is a special tool in the SMT (Surface Mount Technology) production line. It is mainly used to detect whether the position of the surface mount components is consistent when the feeder 20 feeds the components. If the position of the surface mount components is inconsistent, the feeder 20 is controlled to perform calibration to ensure that the pick-and-place machine can accurately pick up the surface mount components.

[0032] refer to Figure 1The feeder loading and alignment fixture 10 includes a support base 11, a positioning component 12, and a detection component 13. The positioning component 12 and the detection component 13 are disposed on the support base 11. The feeder 20 has a feed port 21, and the detection component 13 is disposed corresponding to the feed port 21 of the feeder 20. When the feeder loading and alignment fixture 10 is working, the positioning component 12 restricts the movement of the feeder 20 along the feeder mounting direction. The feed port 21 of the feeder 20 faces the detection component 13, and the detection component 13 detects the position of the surface mount components supplied by the feeder 20. If the detection component 13 detects a deviation between the position of the surface mount component and the feed port 21, the feeder 20 tape can be adjusted by the drive mechanism inside the feeder 20, thereby adjusting the position of the surface mount component relative to the feed port 21. This ensures that the surface mount component is in the same position at the feed port 21 of the feeder 20, avoiding pick-up failure or pick-up offset when the pick-up machine's nozzle picks up the surface mount component supplied by the feed port 21 of the feeder 20 with the same positioning, thus improving the working efficiency of the pick-up machine.

[0033] refer to Figure 2 In some embodiments, the support base 11 includes a first mounting platform 111 and a second mounting platform 112 disposed opposite to each other, and a connecting portion 113 connecting the first mounting platform 111 and the second mounting platform 112. A positioning component 12 is connected to the second mounting platform 112, and a detection component 13 is connected to the first mounting platform 111. In some embodiments, the connecting portion 113, the first mounting platform 111, and the second mounting platform 112 are detachably connected. The first mounting platform 111, the connecting portion 113, and the second mounting platform 112 form an approximately U-shaped structure. The first mounting platform 111 is disposed relative to the second mounting platform 112, and the connecting portion 113 connects the first mounting platform 111 and the second mounting platform 112 and provides support for the first mounting platform 111. The detachable connection is not limited to threaded fasteners, snap-fit ​​fasteners, etc. This structural design enables rapid assembly of the connecting portion 113, the first mounting platform 111, and the second mounting platform 112 and reduces the processing difficulty of the support base 11.

[0034] Also refer to Figure 1 and Figure 2 In some embodiments, the first mounting platform 111 includes a support plate 1111 and a mounting plate 1112 connected to the support plate 1111. The support plate 1111 is connected to the connecting portion 113 and extends along the feeder mounting direction. The mounting plate 1112 protrudes from the side of the support plate 1111 away from the first mounting platform 111. The detection assembly 13 is detachably connected to the mounting plate 1112. Figure 2As shown, the mounting plate 1112 and the support plate 1111 can be approximately rectangular plates. One end of the support plate 1111 is connected to one end of the connecting portion 113, and the mounting plate 1112 is connected to the opposite end of the support plate 1111, or in other words, the mounting plate 1112 is connected to the end of the support plate 1111 that is away from the connecting portion 113. The included angle between the mounting plate 1112 and the support plate 1111 can be 90 degrees or other angles, as long as it ensures that when the detection component 13 is mounted on the mounting plate 1112, the detection component 13 corresponds to the feed port 21. For example, the detection component 13 can be a camera, which can take pictures of the feed port 21 and the surface mount components within it. After subsequent image processing, it can be confirmed whether the position of the surface mount components within the feed port 21 is in a preset position. Therefore, in this embodiment, it is only necessary to ensure that the image acquisition range of the detection component 13 covers the feed port 21.

[0035] Furthermore, the support plate 1111 is detachably connected to the connecting part 113, and the support plate 1111 has an oblong hole 11111, which extends along the feeder mounting direction to adjust the position of the detection component 13 in the feeder mounting direction, ensuring that the detection range of the detection component 13 covers the feed port 21 of the feeder 20, so that the detection component 13 can accurately identify the position of the surface mount component relative to the feed port 21, and ensure the accuracy of the detection.

[0036] In some embodiments, the second mounting platform 112 includes a latching portion 1121 that mates with the feeder 20. The latching portion 1121 is located at the end of the second mounting platform 112 away from the connecting portion 113. The latching portion 1121 is used to engage with the elastic swing arm 23 of the feeder 20 to limit the feeder 20. (Reference) Figure 2 The feeder 20 may include a main body 22 and an elastic swing arm 23 oscillatingly connected to the main body 22. During the process of the feeder 20 being installed in the feeder loading and straightening fixture 10 along the feeder installation direction, the latching part 1121 can drive the elastic swing arm 23 to open so that the latching part 1121 enters between the main body 22 and the elastic swing arm 23. When the feeder 20 is installed in place in the feeder loading and straightening fixture 10, the elastic swing arm 23, under the action of an elastic restoring force such as the restoring force of a torsion spring, realizes the engagement of the latching part 1121 and the elastic swing arm 23, thereby restricting the movement of the feeder 20 in the feeder installation direction.

[0037] Also refer to Figure 2 , Figure 3 and Figure 4In some embodiments, the positioning component 12 may have a limiting groove 121 extending along the feeder mounting direction. The feeder 20 is limited in the limiting groove 121, which engages with the side of the feeder 20 near the first mounting platform 111 to restrict the movement of the feeder 20 in a first direction. In some embodiments, the first direction is perpendicular to the feeder mounting direction. Exemplarily, the shape of the limiting groove 121 is adapted to the shape of the bottom of the feeder 20, such that after the feeder 20 is embedded in the limiting groove 121, there can be a transition fit or clearance fit between the feeder 20 and the groove wall of the limiting groove 121 on opposite sides in the first direction, thereby restricting the movement of the feeder 20 in the first direction.

[0038] Specifically, the side of the second mounting platform 112 facing the first mounting platform 111 is recessed to form a first mounting groove 1122. The positioning assembly 12 includes a first limiting member 122, which is limited within the first mounting groove 1122 and has a limiting groove 121. Exemplarily, the first limiting member 122 is detachably connected to the second mounting platform 112 by a threaded fastener and is limited within the first mounting groove 1122.

[0039] Further, refer to Figure 3 The first limiting member 122 includes a body 1221 and two protruding arms 1222 extending from one end of the body 1221. The limiting groove 121 includes a first groove 1211 and a second groove 1212 communicating with the first groove 1211. The body 1221 has the first groove 1211, and the two protruding arms 1222 form the second groove 1212, and the width of the second groove 1212 is greater than the width of the first groove 1211. The bottom of the first groove 1211 of the body 1221 can be flush with or slightly lower than the surface of the second mounting platform 112 facing the feeder 20, so as to facilitate the feeder 20 being installed into the limiting groove 121 along the feeder mounting direction.

[0040] like Figure 3 As shown, the first groove 1211 of the body 1221 has symmetrical protruding structures 12211 on both sides of the groove wall. The protruding structures 12211 extend along the inner side of the groove wall and can form a guide groove 12212 with the bottom of the first groove 1211. The width of the guide groove 12212 is greater than the distance between the two protruding structures 12211. When the feeder 20 enters the limiting groove 121 along the feeder installation direction, the protruding structures 12211 can play a guiding or limiting role. (See also...) Figure 4The main body 22 of the feeder 20 can be equipped with a flange structure 24 adapted to the guide groove 12212 to better restrict the movement of the feeder 20 in the first direction. The connection between the first groove 1211 and the second groove 1212 can be transitioned by a slope. When installing the feeder 20, the second groove 1212 provides initial guidance and alignment for the feeder 20, and then the slope smoothly guides the feeder 20 into the first groove 1211, so that the main body 22 and flange structure 24 of the feeder 20 can accurately cooperate with the protrusion structure 12211 and the guide groove 12212, reducing impact during installation and improving installation efficiency and reliability.

[0041] Furthermore, the body 1221 of the first limiting member 122 is detachably limited in the first mounting groove 1122. This modular structure facilitates the independent processing of the first limiting member 122, enables the rapid assembly of the first limiting member 122 with the second mounting platform 112, and allows for rapid replacement when the first limiting member 122 fails, without disassembling the entire first mounting platform 111, significantly improving the convenience of maintenance.

[0042] refer to Figure 2 and Figure 5 In some embodiments, the positioning component 12 includes a second limiting member 123 detachably connected to the second mounting platform 112. The second limiting member 123 protrudes from the second mounting platform 112 and is spaced apart from the first limiting member 122 in the feeder mounting direction. The second limiting member 123 has a positioning hole 1231 for cooperating with the positioning pin 25 of the feeder 20 to limit the feeder 20. After the feeder 20 is installed on the feeder loading and straightening fixture 10, on the one hand, the positioning hole 1231 of the second limiting member 123 cooperates with the positioning pin 25 of the feeder 20, and the latching part 1121 of the second mounting platform 112 cooperates with the elastic swing arm 23 of the feeder 20, restricting the movement of the feeder 20 in the feeder installation direction and the second direction; on the other hand, the positioning hole 1231 of the second limiting member 123 cooperates with the positioning pin 25 of the feeder 20, and the limiting groove 121 of the first limiting member 122 cooperates with the feeder 20, restricting the movement of the feeder 20 in the first direction and the second direction, thereby achieving reliable positioning of the feeder 20 on the feeder straightening fixture 10. The first direction, the second direction and the feeder installation direction are perpendicular to each other.

[0043] Continue to refer to Figure 2 and Figure 5 In some embodiments, the second mounting platform 112 has a second mounting groove 1123 for mounting the second limiting member 123. For example... Figure 2As shown, the connecting portion 113 can be L-shaped overall, including a first structure 1131 extending in a second direction and a second structure 1132 extending along the feeder mounting direction. One end of the first structure 1131 is connected to the first mounting platform 111, and the other end is fixedly connected to the second structure 1132. The second structure 1132 of the connecting portion 113 and the second mounting platform 112 can be detachably connected by threaded fasteners. The surface of the second mounting platform 112 connected to the second structure 1132 can be stepped. The second structure 1132 is mounted on the second mounting platform 112 and forms a second mounting groove 1123 with the second mounting platform 112. The surface of the second structure 1132 facing the first mounting platform 111 can protrude from the surface of the second mounting platform 112 facing the first mounting platform 111, ensuring that the second limiting member 123 is securely embedded in the second mounting platform 112.

[0044] refer to Figure 5 In some embodiments, the recessed side of the second limiting member 123 facing the first limiting member 122 can form a groove 1232. A through hole 12321 is provided at the bottom of the groove 1232 for inserting the communication interface 26 of the feeder 20. Positioning holes 1231 are provided at opposite ends of the second limiting member 123, spaced apart from the groove 1232. When the feeder 20 is installed on the feeder calibration fixture 10, the communication interface 26 of the feeder 20 within the through hole 12321 can interface with the interface of the pick-and-place machine, enabling communication between the feeder calibration fixture 10 and the pick-and-place machine. When the detection component 13 detects a deviation in the position of the surface mount element, the control system of the pick-and-place machine can control the drive mechanism of the feeder 20 in real time through the communication interface 26, thereby precisely adjusting the position of the surface mount element of the tape at the feeder 20 feed port 21, ensuring that the position of the surface mount element at the feeder 20 feed port 21 remains consistent.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
