Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chip manufacturing, in particular to a magazine conveying device and a chip sorting machine. BACKGROUND

[0002] In the manufacturing process of chips, detection, packaging, sorting and other processes are needed. When sorting chips, the feeding method is basically to use a turntable feeding device or a mechanical hand for feeding.

[0003] When using a turntable feeding device for feeding, a plurality of workstations are usually provided on the turntable, and a plurality of magazines are needed to participate in conveying. Such a setting not only occupies more workstations of the turntable, resulting in a larger size of the turntable and the need for a larger assembly space; moreover, the setting of multiple magazines causes the stroke size of the subsequent handling mechanical hand to become larger, increasing the cost. When using a mechanical hand for feeding, a magazine and X, Y and Z movements of the mechanical hand are still needed, but there is still a waiting time when the mechanical hand feeds, resulting in low continuity of the feeding rhythm. Even if two parallel magazines are matched to ensure the feeding rhythm, there is still a waiting time, affecting the feeding efficiency. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a magazine conveying device which not only does not need a larger assembly space, but also improves the feeding rhythm and efficiency.

[0005] A magazine conveying device comprises a first conveying mechanism and a second conveying mechanism; the first conveying mechanism and the second conveying mechanism each comprise a Y-direction conveying group and an X-direction conveying group connected to the Y-direction conveying group, two Y-direction conveying groups are arranged at intervals along the X-direction, and the X-direction and the Y-direction are at an angle; at least one of the two Y-direction conveying groups is provided with a feeding area, a discharging area and an interference area arranged along the Y-direction, the interference area is arranged between the feeding area and the discharging area, and at least one of the two X-direction conveying groups can move in the X-direction away from the other in the interference area.

[0006] It can be understood that, by using the arrangement of the first conveying mechanism and the second conveying mechanism, material conveying can be carried out respectively, for example, the first conveying mechanism can be used for loading in the loading area, and the second conveying mechanism can be used for unloading in the unloading area. When the second conveying mechanism unloads and the corresponding X-direction conveying group returns to the loading area, the first conveying mechanism carries the material to the unloading area for unloading. When the two X-direction conveying groups move to the interference area, at least one of them moves away from the other side along the X-direction to avoid interference. Such an arrangement reduces the waiting time of the two conveying mechanisms on both sides along the Y-axis direction, and improves the conveying rhythm. Moreover, due to the arrangement of the interference area, the two X-direction conveying groups can adjust to each other to reduce interference and further improve the conveying efficiency. In addition, the first conveying mechanism and the second conveying mechanism cooperate to realize material loading and conveying, without the need to add other auxiliary structures, thereby reducing the occupied assembly space.

The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0032] Please refer to Figures 1 to 3 An embodiment of the present application provides a shuttle conveying device for feeding in the chip manufacturing process, which not only does not need a large assembly space, but also improves the feeding rhythm and efficiency. Specifically, the shuttle conveying device includes a first conveying mechanism 110 and a second conveying mechanism 120, both of which include a Y-direction conveying group 101 and an X-direction conveying group 102 connected to the Y-direction conveying group 101. The conveying directions of the two Y-direction conveying groups 101 are along the Y-direction and are arranged at intervals along the X-direction. The conveying directions of the two X-direction conveying groups 102 are along the X-direction. The X-direction and the Y-direction are arranged at an angle, for example, the X-direction and the Y-direction are perpendicular.

[0033] At least one of the two Y-direction conveying groups 101 is provided with a loading area 103, a discharging area 104 and an interference area 105 arranged along the Y-direction, and the interference area 105 is arranged between the loading area 103 and the discharging area 104. The loading area 103 is used for the magazine conveying device to load materials from other processes, for example, the chips after detection. The discharging area 104 is used for the magazine conveying device to unload materials, so as to transfer the chips to the next process. The interference area 105 is the area where the two X-direction conveying groups 102 interfere with each other when moving along the Y-direction. In the embodiment, at least one of the two X-direction conveying groups 102 can move along the X-direction away from the other in the interference area 105.

[0034] It should be noted that the movement of the X-direction conveying group 102 along the X-direction is specifically the movement of the part of the X-direction conveying group 102 loaded with the tray 200 along the X-direction. In actual use, each X-direction conveying group 102 includes an X-direction driving part (not shown in the figure) and an X-direction support seat 1022 connected to the X-direction driving part, the X-direction support seat 1022 moves along the X-direction under the action of the X-direction driving part, and the X-direction support seat 1022 is used to load the tray 200. Therefore, the movement of at least one of the two X-direction conveying groups 102 along the X-direction away from the other in the interference area 105 means that the corresponding X-direction support seat 1022 of at least one of the two X-direction conveying groups 102 can move along the X-direction away from the other in the interference area 105.

[0035] Among them, in order to facilitate the description, the first conveying mechanism 110 corresponds to the first X-direction conveying group and the first Y-direction conveying group, and the second conveying mechanism 120 corresponds to the second X-direction conveying group and the second Y-direction conveying group.

[0036] That is, by cooperating the first conveying mechanism 110 and the second conveying mechanism 120, the material conveying can be carried out respectively, for example, the first X-direction conveying group in the first conveying mechanism 110 can move to the loading area 103 to load materials, and the second X-direction conveying group in the second conveying mechanism 120 can move to the discharging area 104 to unload materials. When the two X-direction conveying groups 102 complete the corresponding loading and unloading respectively, the first X-direction conveying group moves along the Y-direction towards the discharging area 104 under the action of the corresponding first Y-direction conveying group, and the second X-direction conveying group returns to the loading area 103 along the Y-direction under the action of the corresponding second Y-direction conveying group. Therefore, when the two X-direction conveying groups 102 move to the interference area 105, the X-direction support seat 1022 of at least one of the X-direction conveying groups 102 can move along the X-direction away from the other side, so as to avoid interference; and the movement of the X-direction support seat 1022 along the X-direction will not affect the movement of the X-direction conveying group 102 along the Y-direction.

[0037] For example, the X-direction support seat 1022 of the first X-direction conveying group can move along the X-direction to the side away from the second X-direction conveying group; or, the X-direction support seat 1022 of the second X-direction conveying group can move along the X-direction to the side away from the first X-direction conveying group; or, the X-direction support seats 1022 of the first X-direction conveying group and the second X-direction conveying group can move away from each other along the X-direction.

[0038] In summary, the material shuttle conveying device provided in the embodiment reduces the waiting time of each conveying mechanism for loading and unloading on both sides along the Y-axis direction and improves the conveying rhythm by using the first conveying mechanism 110 and the second conveying mechanism 120 to cooperate with the conveying along the Y-direction and the X-direction, respectively. Meanwhile, during the conveying process, the interference area 105 is arranged to adjust the two X-direction conveying groups 102 to reduce the interference and further improve the conveying efficiency. In particular, when the two X-direction conveying groups 102 have driving along the X-direction in the interference area 105, the movement path of each X-direction conveying group 102 can be reduced to further reduce the waiting time. Moreover, due to the arrangement of the interference area 105, a coincident area is arranged in the X-direction of the two X-direction conveying groups 102, which further reduces the size of the material shuttle conveying device along the X-direction and reduces the occupied space. In addition, the material shuttle conveying device does not need to add other auxiliary structures, and only relies on the cooperation of the first conveying mechanism 110 and the second conveying mechanism 120 to realize the material loading and conveying, thereby reducing the overall occupied assembly space and facilitating integration in more different use devices.

[0039] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 As some examples, the material shuttle conveying device further comprises a Y-direction detection assembly 130 connected to the Y-direction conveying group 101 and / or the corresponding X-direction conveying group 102, and at least one X-direction conveying group 102 is configured to move away along the X-direction in response to the detection signal of the Y-direction detection assembly 130. That is, the Y-direction detection assembly 130 can be arranged to detect the position of the X-direction conveying group 102 along the Y-direction, and then feedback in time so that the X-direction support seat 1022 in the X-direction conveying group 102 can move along the X-direction to reduce the interference of the two X-direction conveying groups 102 along the X-direction and ensure the conveying reliability. Each Y-direction conveying group 101 is correspondingly provided with a set of Y-direction detection assemblies 130.

[0040] As Figures 3 to 5As shown, specifically, each of the two Y-direction conveying groups 101 comprises a Y-direction rail 1011 and a Y-direction support seat 1012 slidingly connected to the Y-direction rail 1011. Meanwhile, each of the two Y-direction conveying groups 101 further comprises a Y-direction driving part (not shown in the figure), and the Y-direction support seat 1012 is connected to the Y-direction driving part and moves along the length direction of the Y-direction rail 1011 under the action of the corresponding Y-direction driving part. The length direction of the Y-direction rail 1011 is the Y-axis direction (referred to as Y-direction). The two X-direction conveying groups 102 are respectively mounted on the corresponding Y-direction support groups, thereby realizing the Y-direction movement of the X-direction conveying group 102.

[0041] The Y-direction detection assembly 130 comprises a detection rail 131 extending along the Y-direction and a Y-direction sensor 132 mounted on the Y-direction support seat 1012. Of course, the Y-direction sensor 132 can also be mounted on the corresponding X-direction conveying group 102 of the Y-direction support seat 1012; or, part of the Y-direction sensor 132 is mounted on the Y-direction support seat 1012, and the other part is connected to the X-direction conveying group 102. As long as it can ensure that the Y-direction sensor 132 can move along the Y-direction with the X-direction conveying group 102.

[0042] When the Y-direction sensor 132 moves with the Y-direction support seat 1012, it can cooperate with the detection rail 131 to feedback different detection signals in the Y-direction. Specifically, it prompts the X-direction conveying group 102 to be located in one of the feeding area 103, the discharging area 104 and the interference area 105, thereby facilitating timely movement feedback and avoidance in the interference area 105, improving response timeliness, and further improving the feeding rhythm.

[0043] As shown in some specific embodiments, Figures 3 to 5 The length L1 of the two shielding pieces 1311 along the Y-direction is less than the length L2 of the Y-direction rail 1011, and one of the shielding pieces 1311 is provided with a gap area 1310. That is, different detection signals can be fed back through the structural arrangement of the detection rail 131, thereby judging the position area of the X-direction conveying group 102 in the Y-direction.

[0044] Taking the Y-direction sensor 132 as an example, two Y-direction sensors 132 are arranged along the X-direction on the Y-direction support seat 1012, and each Y-direction sensor 132 corresponds to a shielding piece 1311. Among them, the two Y-direction sensors 132 can both adopt a reflection type sensor. Therefore, when the Y-direction sensor 132 is shielded by the shielding piece 1311, the Y-direction sensor 132 feeds back a "1" signal, and when the Y-direction sensor 132 is not shielded, it feeds back a "0" signal.

[0045] Based on this, since the lengths of the two shielding pieces 1311 along the Y direction are both less than the length of the Y direction track 1011, the part of the Y direction track 1011 protruding the shielding piece 1311 in the Y direction can be defined as a blank area. Therefore, when the two Y direction sensors 132 move to the blank area with the Y direction support seat 1012, neither of the two Y direction sensors 132 is shielded, and then a "00" signal is fed back. Meanwhile, the part of the shielding piece 1311 used for shielding the Y direction sensor 132 is defined as a shielding area, and then when the two Y direction sensors 132 move to the shielding area, a "11" signal is fed back. Moreover, since one of the shielding pieces 1311 is provided with a notch area 1310, when the corresponding Y direction sensor 132 moves to the notch area 1310, it will not be shielded, while the other shielding piece 1311 does not have a notch area 1310, and then shields the corresponding Y direction sensor 132, at this time, the two Y direction sensors 132 feed back a "10" signal. In this way, the Y direction track 1011 along the Y direction can be divided into the feeding area 103, the interference area 105 and the discharging area 104 according to the different signals fed back.

[0046] Among them, the area corresponding to the blank area is used as the discharging area 104, the area corresponding to the two shielding areas is used as the interference area 105, and the area corresponding to the one shielding area and the one notch area 1310 is used as the feeding area 103. Or, the area corresponding to the blank area is used as the feeding area 103, the area corresponding to the two shielding areas is used as the discharging area 104, and the area corresponding to the one shielding area and the one notch area 1310 is used as the interference area 105. Or, the area corresponding to the blank area is used as the discharging area 104, the area corresponding to the two shielding areas is used as the feeding area 103, and the area corresponding to the one shielding area and the one notch area 1310 is used as the interference area 105. Here, only examples are given.

[0047] Alternatively, both of the shielding pieces 1311 can be provided with a notch area 1310, and the two notch areas 1310 are arranged staggered along the Y direction. This results in that the signals fed back by the different notch areas 1310 are "10" and "01", which can be used to distinguish different areas.

[0048] In other embodiments, the shielding piece 1311 can also be three. At this time, one of the shielding pieces 1311 can have a length along the Y direction substantially the same as the length of the Y direction track 1011, and the lengths of the other two shielding pieces 1311 are less than the length of the Y direction track 1011, and one of the two shielding pieces 1311 with smaller length is provided with a notch area 1310. Or, the lengths of two of the shielding pieces 1311 are the same as the length of the Y direction track 1011, and the length of the other shielding piece 1311 is less than the length of the Y direction track 1011, and one of the two shielding pieces 1311 with longer length is provided with a notch area 1310. Here, only examples are given.

[0049] Alternatively, each Y-direction track 1011 can be provided with three shielding pieces 1311 arranged at intervals along the Y direction, and each Y-direction support base 1012 can be provided with a Y-direction sensor 132, which can be triggered when moving to a region.

[0050] Please refer to Figure 5 As another example, the shuttle conveying device further comprises an X-direction detection assembly 140 arranged between the Y-direction support base 1012 and the X-direction conveying assembly 102, and the Y-direction conveying assembly 101 is configured to drive the X-direction conveying assembly 102 to move along the Y direction in response to a detection signal of the X-direction detection assembly 140. That is, the X-direction detection assembly 140 is arranged to detect and determine the position of the X-direction support base 1022, and the Y-direction conveying is performed only when the X-direction support base 1022 is in a safe position, thereby improving the conveying safety. When the X-direction support base 1022 is not moved to the safe position, the X-direction driving part can be started to drive the X-direction support base 1022 to move.

[0051] In actual use, the X-direction detection assembly 140 comprises a trigger piece 141 and an X-direction sensor 142, one of which is arranged on the Y-direction support base 1012 and the other is arranged on the X-direction support base 1022. The X-direction sensor 142 can be triggered by the trigger piece 141 to emit a detection signal. That is, only when the trigger piece 141 triggers the X-direction sensor 142 to emit a detection signal, it is proved that the X-direction support base 1022 is in a safe position, and then the Y-direction driving part is started to drive the Y-direction support base 1012 to move along the Y direction, thereby driving the entire X-direction conveying assembly 102 to move along the Y direction. If the trigger piece 141 does not trigger the X-direction sensor 142, it is proved that the position of the X-direction support base 1022 still needs to be adjusted.

[0052] Further, the X-direction sensor 142 can be arranged on the Y-direction support base 1012, and the trigger piece 141 can be arranged on the X-direction support base 1022. At this time, with respect to the two X-direction detection assemblies 140 corresponding to the two X-direction conveying assemblies 102 respectively, the X-direction sensor 142 corresponding to each of them is located on the side opposite to the two Y-direction support bases 1012, thereby defining the safe position of the Y-direction conveying assembly 101 driven, and reducing the movement interference of the two X-direction conveying assemblies 102.

[0053] Further, one X-direction sensor 142 is further arranged on the side opposite to the two X-direction sensors 142 respectively, for limiting the movement of the X-direction support base 1022. When this X-direction sensor 142 is triggered, the X-direction support base 1022 needs to be adjusted to move along the X direction away from the other X-direction support base 1022.

[0054] Among them, the X-direction sensor 142 adopts a reflection type sensor.

[0055] Please refer to Figure 2 , Figure 5 and Figure 6 , in optional embodiments, each X-direction support base 1022 comprises a first support arm 1022a and a second support arm 1022b connected to the first support arm 1022a, and both are arranged at an angle, for example, in an L shape. The first support arm 1022a is in sliding connection with the X-direction rail 1021 and is connected with the X-direction driving part. The first support arm 1022a extends along the X-direction. The second support arm 1022b is connected to one end of the first support arm 1022a along the X-direction, and is mainly used for loading the tray 200. For two X-direction conveying groups 102, the respective corresponding second support arm 1022b is located on the same side of the respective corresponding first support arm 1022a along the Y-direction. For example, both second support arms 1022b can be located on the lower side of the respective corresponding first support arm 1022a along the Y-direction, or on the upper side. Figure 2

[0056] It can be understood that by arranging the first support arm 1022a and the second support arm 1022b at an angle, the occupied space in a single direction, especially along the Y-direction, can be reduced, thereby reducing the interference of each X-direction conveying group 102 in the X-direction and optimizing the space utilization. At the same time, due to the same side arrangement of the second support arms 1022b of the two X-direction conveying groups 102, the occupied space along the Y-direction is further reduced, and the cooperation reference of the two X-direction conveying groups 102 relative to other structures is basically the same, without the need to adjust the loading or unloading position each time.

[0057] Please refer to Figure 3 , Figure 5 and Figure 6 , in some embodiments, the two Y-direction conveying groups 101 adopt screw drive. Taking the Y-direction driving part of the Y-direction conveying group 101 as an example, the Y-direction driving part comprises a Y-direction lead screw 11 and a Y-direction nut 12 in threaded transmission connection with the Y-direction lead screw 11, and a Y-direction support base 1012 connected to the Y-direction nut 12. The Y-direction lead screw 11 rotates around its own axis to drive the Y-direction nut 12 to move along the Y-direction lead screw 11 in the axial direction (i.e. Y-direction), thereby synchronously moving the Y-direction support base 1012. The Y-direction driving part further comprises a Y-direction belt transmission 13 and a Y-direction power source 14, the Y-direction power source 14 is in transmission connection with one pulley of the Y-direction belt transmission 13, and the other pulley of the Y-direction belt transmission 13 is in transmission connection with the Y-direction lead screw 11, thereby realizing the rotation of the Y-direction lead screw 11.
