Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0038] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly.

[0041] Referring to Figures 1 and 2, Figure 1 shows an axial schematic diagram of a reflow assembly 10 provided in one embodiment of the present application, and Figure 2 shows a front view of the reflow assembly 10 shown in Figure 1. The reflow assembly 10 provided in one embodiment of the present application is intended for use in an inspection machine. The reflow assembly 10 includes a support plate 100, a carrier 200, and a drive structure 300. There are at least two carriers 200, and the drive structure 300 connects the at least two carriers 200. The support plate 100 is provided with a track structure 110, the ends of which are respectively positioned at the loading and unloading ends of the inspection machine. The carriers 200 are used to carry workpieces, and the at least two carriers 200 are slidably engaged with the track structure 110. When one of the carriers 200 is positioned at the end of the track structure 110 near the loading end, the other carrier 200 is positioned at the end of the track structure 110 near the unloading end. The drive structure 300 drives the carriers 200 to move synchronously along the track structure 110.

[0042] The reflow assembly 10 is installed in the inspection machine. Because the carrier 200 can carry workpieces, the drive mechanism 300 drives the carrier 200 along the track structure 110, transporting the workpieces from the unloading end of the inspection machine back to the loading end. This allows workpieces mistakenly detected as defective to be re-inspected by the inspection machine at the loading end. This secondary inspection reduces the false positive rate.

[0043] Furthermore, there are multiple carriers 200, and while one carrier 200 is located at the end of the track structure 110 near the loading end, another carrier 200 is located at the end of the track structure 110 near the unloading end. This arrangement ensures that while one carrier 200 is loading a workpiece at the unloading end, another carrier 200 is always removing a workpiece at the loading end. Consequently, the reflow assembly 10 can simultaneously load and remove workpieces, enabling continuous workpiece transport, thereby improving the efficiency of transporting workpieces for re-inspection.

[0044] It should be noted that the drive structure 300 drives each carrier 200 synchronously. Therefore, when the carrier 200 at the unloading end moves to the loading end, the carrier 200 at the loading end also moves to the unloading end. Thus, by having at least two carriers 200 complement each other, the continuity of workpiece transport by the reflow assembly 10 is improved, waiting time is reduced, and efficiency is increased. As shown in Figure 1, the end labeled SL is the loading end; the end labeled XL is the unloading end.

[0045] Please continue to refer to Figures 1 and 2. In one embodiment, the driving structure 300 includes a driving wheel 310 and a synchronous belt 320. The synchronous belt 320 is wound around the driving wheel 310. When the driving wheel 310 rotates, it can drive the synchronous belt 320 to move. Each carrier 200 is fixedly connected to a different position of the synchronous belt 320 to achieve the staggered operation as described above. Among them, when one carrier 200 is located on the side of the track structure 110 close to the loading end, the other carrier 200 is located on the end of the track structure 110 close to the unloading end. In this embodiment, it is arranged so that each carrier 200 can be driven to move synchronously through a belt transmission with a simple structure. When the structure of the reflux component 10 is simplified, it is convenient to realize a reflux conveying method in which each carrier 200 complements each other, so that the reflux component 10 can achieve continuous conveying of workpieces.

[0046] Please refer to Figures 2 and 3. There are two driving wheels 310. The two driving wheels 310 are rotatably arranged on one side of the support plate 100 close to the loading end of the inspection machine and on the other side of the inspection machine close to the unloading end, so as to drive each carrier 200 to move synchronously between the loading end and the unloading end through the synchronous belt 320.

[0047] 2 , the driving structure 300 further includes a driver 330 . The driver 330 is disposed on the support plate 100 and connected to the driving wheel 310 to rotate the driving wheel 310 .

[0048] Referring again to Figures 1 and 2 , in one embodiment, the track structure 110 includes a first track 111 and a second track 112 , which are arranged side by side and spaced apart. The first track 111 and the second track 112 can be arranged on either side of a timing belt 320 , respectively. The direction in which the timing belt 320 drives the carrier 200 to move is parallel to both the first track 111 and the second track 112 .

[0049] Referring to Figures 1 to 3 , the carrier 200 includes a first carrier 210 and a second carrier 220. The first carrier 210 slidably engages with the first track 111, while the second carrier 220 slidably engages with the second track 112. The first track 111 includes a first loading section 111a, a first unloading section 111b, and a first intermediate section 111c. The first loading section 111a corresponds to the unloading end, the first unloading section 111b corresponds to the loading end, and the first intermediate section 111c is connected between the first loading section 111a and the first unloading section 111b. As shown in Figure 4 , the first carrier 210 includes a first connecting plate 211 and a first platform 212. The first connecting plate 211 slidably engages with the first track 111, and the first platform 212 is movably mounted on the first connecting plate 211. The reflux assembly 10 also includes a push-up structure 400 connected to the first carrier 212. When the first carrier 210 is located in the first intermediate section 111b, the push-up structure 400 pushes the first carrier 212 away from the second track 112 to a position offset from the second carrier 220. It should be understood that the offset refers to offset along the length of the second track 112. Because each carrier 200 is fixedly connected to a different position on the timing belt 320, the first and second carriers 210, 220 typically meet in the middle area of ​​the track structure 110 during mutually complementary reflux transport. Specifically, the first carrier 210 typically meets the second carrier 220 while moving in the first intermediate section 111c. Therefore, in this embodiment, by arranging that when the first carrier 210 is located in the first intermediate section 111c, the push-up structure 400 drives the first carrier 212 to a position away from the second carrier 220, the probability of collision between the first carrier 210 and the second carrier 220 during their movement toward each other can be reduced. In other words, there is no need to set a wide spacing between the first track 111 and the second track 112 to avoid mutual collision or interference, or to place the first carrier 210 and the second carrier 220 on different sides of the support plate 100 to avoid mutual collision or interference.

[0050] Furthermore, since this embodiment pushes the first carrier 212 to avoid the second carrier 220 through the pushing structure 400, it allows the first carrier 210 and the second carrier 220 to be set to the same horizontal position in the area where they will not meet (such as the first filling section 111a, the first unloading section 111b and the second filling section 112a and the second unloading section 112b on the second track 112 mentioned below), so as to facilitate the removal of workpieces at the loading end of the inspection machine and the loading of workpieces at the unloading end of the inspection machine.

[0051] As shown in Figure 3, in one embodiment, similar to the first track 111, the second track 112 includes a second loading section 112a, a second unloading section 112b, and a second intermediate section 112c. The second loading section 112a corresponds to the unloading end, the second unloading section 112b corresponds to the loading end, and the second intermediate section 112c is connected between the second loading section 112a and the second unloading section 112b. In the direction in which the synchronous belt 320 drives the carrier 200, the first loading section 111a and the second loading section 112a are in the same position, the first unloading section 111b and the second unloading section 112b are in the same position, and the first intermediate section 111c and the second intermediate section 112c are in the same position.

[0052] Continuing with Figures 2 and 3 , in one embodiment, the push-up structure 400 may include a guide groove 410 defined in the support plate 100 , with a portion of the first carrier 212 movably disposed within the guide groove 410 and abutting against the walls of the guide groove 410 . The guide groove 410 can guide and limit the movement of the first carrier 212 . Specifically, when the first carrier 210 slides to a position where it intersects with the second carrier 220 , the walls of the guide groove 410 can push the first carrier 212 away from the second track 112 to a position offset from the second carrier 220 . For example, the first carrier 212 can engage in a rolling or sliding manner with the walls of the guide groove 410 .

[0053] As shown in Figure 3 , the guide groove 410 is elongated, with the line connecting the two ends of the guide groove 410 parallel to the track structure 110. Specifically, the line connecting the two ends of the guide groove 410 is parallel to the first track 111 and the second track 112. This line is indicated by the symbol L in Figure 3 . Furthermore, the lengths of the two ends of the guide groove 410 extend parallel to the track structure 110, and the region of the guide groove 410 located between the two ends is located away from the second track 112 relative to the two ends. It is readily understood that when the first carrier 210 is located on the side of the track structure 110 near the loading end, the second carrier 220 is located on the end of the track structure 110 near the unloading end. Furthermore, the first and second carriers 210, 220 achieve synchronized motion via the synchronous belt 320. Therefore, the region where the first and second carriers 210, 220 meet is approximately located in the middle of the track structure 110. Therefore, by setting the area in the middle of the guide groove 410 to be located away from the second track 112 relative to the two end portions, the first carrier 212 can be limited to a position away from the second carrier 220, so that the first carrier 212 and the second carrier 220 are staggered in the area where the first carrier 210 and the second carrier 220 may meet.

[0054] Furthermore, since the areas at both ends of the guide groove 410 are still located relatively close to the second rail 112, the first carrier 210 and the second carrier 220 can still be set to the same horizontal position in the area where they will not meet, so as to facilitate the removal of the workpiece by the loading end of the inspection machine and the loading of the workpiece by the unloading end of the inspection machine.

[0055] Furthermore, referring to Figures 2 and 3, in one embodiment, the guide channel 410 includes a loading section 411, a loading section 412, and a pushing section 413. The pushing section 413 is connected between the loading section 411 and the loading section 412. The loading section 411 is located at the end of the track structure 110 near the loading end. The loading section 412 is located at the end of the track structure 110 near the loading end. The loading section 412 and the loading section 411 extend in the same direction and are both parallel to the track structure 110. The pushing section 413 is located away from the loading section 412 relative to the loading section 412, so that the first carrier 212 and the second carrier 220 are spaced apart in a direction perpendicular to the second track 112. This arrangement reduces the probability of collision and interference between the first carrier 210 and the second carrier 220 during reciprocating motion, thereby improving coordination between the carriers 200 in the reflow assembly 10 when multiple carriers 200 are transporting workpieces. In this embodiment, the direction in which the first track 111 , the second track 112 and the synchronous belt 320 drive the carrier 200 to move is shown in FIG. 2 and FIG. 3 , and the direction perpendicular to the second track 112 is shown in FIG. 2 and FIG. 3 , which is marked M.

[0056] As shown in Figures 2 and 3 , it can be understood that the guide groove 410 further includes two transition sections 414. One transition section 414 is connected between the adjacent ends of the loading section 411 and the ejection section 413, and the other transition section 414 is connected between the adjacent ends of the unloading section 412 and the ejection section 413. Both transition sections 414 are inclined relative to the second track 112 to guide the movement of the carrier 200 between the ejection section 413 and the loading section 411, and between the ejection section 413 and the unloading section 412.

[0057] As shown in Figure 3 , in the direction in which the synchronous belt 320 moves the carrier 200, the unloading section 412 is co-located with the first loading section 111a, the loading section 412 is co-located with the first unloading section 111b, and the ejecting section 413 and the transition section 414 connecting the two ends of the ejecting section 413 are co-located with the first intermediate section 111c.

[0058] It should be noted that not only the transition section 414 and the ejection section 413 have the function of controlling the position of the first carrier 210 in a direction perpendicular to the second track 112, but the loading section 411 and the unloading section 412 also have the function of controlling the position of the first carrier 210 in a direction perpendicular to the second track 112. The loading section 411 and the unloading section 412 can maintain the first carrier 212 at the same horizontal position as the second carrier 220, so as to facilitate loading and unloading of workpieces from the first carrier 210.

[0059] In conjunction with Figure 5 , the following briefly illustrates three typical positions of the first and second carriers 210, 220 during their movement. The first carrier 210 is shown as P1, and the second carrier 220 is shown as P2. As shown in Figure 5 , when the first carrier 210 reaches the ejection section 413, it is able to maintain a position relatively away from the second track 112 due to the limiting and guiding effects of the ejection section 413, thereby reducing the probability of collision between the first and second carriers 210, 220.

[0060] Of course, as shown in FIG6 , the present application is not limited to providing a single guide groove 410 for limiting and guiding one carrier 200 away from the other carrier 200. Alternatively, the push-up structure 400 may include two guide grooves 410. The two guide grooves 410 respectively guide the two carriers 200 to be staggered in the middle area of ​​the track structure 110 to reduce the probability of collision and interference between the carriers 200.

[0061] Of course, in each embodiment, the number of carriers 200 is not limited to 2. As shown in Figure 7, for example, when the number of carriers 200 is 3, the same applies. The three carriers 200 may include a first carrier 210, a second carrier 220, and a third carrier. In this case, the track structure 110 includes a first track 111, a second track 112, and a third track (not shown, the same below) arranged side by side and spaced apart. When one of the three carriers 200 is located at one end of the track structure 110 close to the feeding end, the second carrier 200 may be located in the area between the two ends of the track structure 110, and the last carrier 200 may be located at one end of the track structure 110 close to the unloading end. The three carriers 200 are all connected to the synchronous belt 320 so as to move synchronously through the synchronous belt 320.

[0062] In this embodiment, the ejection structure 400 may include two guide grooves 410, which are respectively referred to as a first guide groove 420 and a second guide groove 430. The first guide groove 420 corresponds to guiding the first carrier 210, so that the first carrier 210 is misaligned with the second carrier 220 when it meets the second carrier 220. The second guide groove 430 is similarly configured to guide the third carrier 200, so that the third carrier 200 is misaligned with the second carrier 220 when it meets the second carrier 220. In this way, the three carriers 200 are able to coordinately transport workpieces, further improving the transport efficiency of the reflow assembly 10. As shown in FIG7 , the first carrier 210 is shown as P1, the second carrier 220 is shown as P2, and the third carrier is shown as P3.

[0063] It should be noted that the opposing groove walls of the guide groove 410 shown in Figures 2 and 3 are both used to push against the first carrier 212. For example, the upper groove wall is used to push the first carrier 212 from the unloading section 412 to the ejecting section 413, and the lower groove wall is used to push the first carrier 212 from the ejecting section 413 to the loading section 411. However, in each embodiment, only one side of the groove wall in the guide groove 410 can be configured to perform the ejecting function. For example, the upper groove wall can be equipped with a tension spring, which pulls the first carrier 212 to maintain contact with the upper groove wall. The position of the first carrier 212 can be controlled by adjusting the fluctuation of the upper groove wall. The lower groove wall is similarly configured, so it will not be described in detail.

[0064] Of course, the pushing structure 400 is not limited to including the guide groove 410. For example, in some embodiments, the pushing structure 400 includes a linear actuator, which pushes the first carrier 212 away from the second track 112 when the first carrier 210 and the second carrier 220 meet. In this way, the first carrier 212 and the second carrier 220 can also be misaligned to avoid collision or interference between them.

[0065] Referring to Figure 8 , in one embodiment, the first carrier 212 is provided with a rotatable roller 212a that rolls with the wall of the guide groove 410. Thus, the first carrier 212 rolls with the wall of the guide groove 410, thereby improving the smoothness of the position change of the first carrier 212 driven by the wall of the guide groove 410.

[0066] 4 and 8 , in one embodiment, the first connecting plate 211 is provided with a first slide rail 213, the first carrier 212 is slidably engaged with the first slide rail 213, and the extension direction of the first slide rail 213 intersects with the extension direction of the first track 111. By providing the first slide rail 213 on the first connecting plate 211, the first carrier 212 and the first connecting plate 211 are slidably engaged through the first slide rail 213. With such a configuration, on the one hand, the first carrier 212 can still be stably driven by the synchronous belt 320 and move along the first track 111 through the first connecting plate 211. On the other hand, the provision of the first slide rail 213 can improve the stability of the movement of the first carrier 212 in a direction perpendicular to the second track 112. The first slide rail 213 can be configured to be perpendicular to the first track 111 and the second track 112.

[0067] 2 to 4 , when the first connecting plate 211 moves along the first track 111 from the first intermediate section 111c to the first loading section 111a, the transition section 414 pushes the first carrier 212 along the first slide rail 213 toward the second track 112. Combined with the retaining effect of the unloading section 412 on the movement of the first carrier 212 along the first slide rail 213, the first carrier 212 in the first loading section 111a and the second carrier 220 in the second loading position are at the same horizontal position, facilitating workpiece loading.

[0068] Similarly, when the first connecting plate 211 moves along the first track 111 from the first loading section 111a to the first intermediate section 111c, the transition section 414 will push the first carrier 212 to move along the first slide rail 213 away from the second track 112. Combined with the effect of the pushing section 413 on the movement of the first carrier 212 along the first slide rail 213, the first carrier 212 in the first intermediate section 111c and the second carrier 222 in the second intermediate section 112c can be offset to facilitate transportation.

[0069] When the first connecting plate 211 moves along the first track 111 from the first intermediate section 111c to the first unloading section 111b, the transition section 414 pushes the first carrier 212 to move along the first slide rail 213 toward the second track 112. Combined with the effect of the loading section 411 on the first carrier 212's movement along the first slide rail 213, the first carrier 212 in the first unloading section 111b and the second carrier 222 in the second unloading position are kept at the same horizontal position, facilitating the removal of workpieces from the first carrier 212 and the second carrier 220.

[0070] Similarly, when the first connecting plate 211 moves along the first track 111 from the first unloading section 111b to the first intermediate section 111c, the transition section 414 drives the first platform 212 to move along the first slide rail 213 in a direction away from the second track 112. Combined with the effect of the push section 413 on the movement of the first platform 212 along the first slide rail 213, the first platform 212 in the first intermediate section 111c and the second platform 222 in the second intermediate section 112c can be staggered to facilitate transportation.

[0071] Continuing with FIG8 , in one embodiment, the first carrier 210 further includes a first clamping plate 214 and a second clamping plate 215. The first clamping plate 214 is fixedly connected to the first connecting plate 211, and the second clamping plate 215 is detachably mounted on the first clamping plate 214 to clamp the timing belt 320 together with the first clamping plate 214. This facilitates adjustment of the position of the first carrier 210 on the timing belt 320 and facilitates securing the first carrier 210 to the timing belt 320.

[0072] 8 , in one embodiment, at least one of the sides of the first and second clamping plates 214 and 215 facing each other is provided with a plurality of protruding abutting portions 201. The abutting portions 201 protrude to the same height to jointly compress the timing belt 320. Each of the protruding abutting portions 201 may be serrated.

[0073] Referring to Figure 9 , in one embodiment, the second carrier 220 includes a second connecting plate 221 and a second carrier 222. The second connecting plate 221 slidably engages the second rail 112, and the second carrier 222 is fixedly mounted on the second connecting plate 221. The second carrier 220 also includes a third clamping plate 223 and a fourth clamping plate 224 mounted on the second connecting plate 221. The third clamping plate 223 is fixedly mounted on the second connecting plate 221, and the fourth clamping plate 224 is detachably mounted on the third clamping plate 223 to clamp the timing belt 320 together with the third clamping plate 223. This facilitates adjustment of the position of the second carrier 220 on the timing belt 320 and facilitates securing the second carrier 220 to the timing belt 320.

[0074] Similarly, at least one of the side surfaces of the third clamping plate 223 and the fourth clamping plate 224 facing each other may also be provided with a plurality of protruding abutting portions 201 to improve the clamping stability.

[0075] Referring to Figures 8 and 9 , in one embodiment, the carriers 200 have a placement surface 202 for placing workpieces. When each carrier 200 is located on the end of the track structure 110 near the loading end, and when each carrier 200 is located on the end of the track structure 110 near the unloading end, the placement surfaces 202 of each carrier 200 are coplanar. For example, when the first carrier 210 is at the unloading end, the placement surface 202 of the first carrier 210 is at the same horizontal plane as the placement surface 202 of the second carrier 220 when the second carrier 220 is at the unloading end, facilitating loading of workpieces onto the first and second carriers 210, 220, at the unloading end. Similarly, at the loading end, the placement surface 202 of the first carrier 210 when the first carrier 210 is at the loading end and the placement surface 202 of the second carrier 220 when the second carrier 220 is at the loading end are at the same horizontal plane, so as to facilitate removing the workpiece from the first carrier 210 and the second carrier 220 at the loading end.

[0076] The present application also provides a testing device, comprising a testing machine and a reflow assembly 10 as described in the above embodiments. The reflow assembly 10 is mounted on the testing machine, with the two ends of the reflow assembly 10 corresponding to the loading and unloading ends of the testing machine, respectively, so that workpieces that have been inspected once at the unloading end and determined to be defective are transported to the loading end for secondary inspection. In this way, by performing secondary inspection on workpieces determined to be defective, the error rate of the workpieces can be reduced. At the same time, such an arrangement can also provide a basis for further improving the requirements for inspection accuracy.

[0077] In one embodiment, the inspection equipment further includes a pickup assembly and a controller. The controller is configured to record the location information of workpieces determined to be defective by the inspection machine and drive the pickup assembly to pick up the workpieces and place them on the carrier 200. A pickup assembly may also be provided at the loading end to transfer workpieces undergoing reflow inspection from the carrier 200 to the inspection machine.

[0078] In one embodiment, the picking component may be a robot arm or the like.

[0079] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
