[0035] This utility model proposes a feed tower structure for use in a chip mounter, wherein the chip mounter is provided with an installation position for installing the feed tower structure.

[0036] Please refer to Figure 1. In one embodiment of this utility model, the feed tower structure includes:

[0037] A first storage section 100 is fixed to the mounting position, and a second storage section 200 is detachably connected to the first storage section 100. It should be noted that the first storage section 100 is fixed to the mounting position by screws. Furthermore, after the first storage section 100 is fixed to the mounting position, the second storage section 200 is detachably connected to the first storage section 100. The second storage section 200 can be detachably connected to the first storage section 100 through a detachable structure. Furthermore, the first storage section 100 is provided with a first storage cavity 110, which has at least three storage positions. The second storage section 200 is provided with a second storage cavity 210, which has at least two storage positions. These storage positions are used to place a feeding tray 300, which is used for placing materials. The second storage cavity 210 is used to supply materials to the first storage cavity 110 and to receive empty trays 300 from the first storage cavity 110. It should be noted that the second storage cavity 210 supplies materials to the first storage cavity 110 via the tray 300. Furthermore, the first storage cavity 110 is used to supply materials to the placement station of a chip mounter, also via the tray 300. It should also be noted that existing pick-and-place machines have two feed tower structures that alternately supply material to the machine. However, each feed tower structure occupies one workstation, meaning that the two feed tower structures occupy two workstations of the pick-and-place machine. This operation is not conducive to the compact design of the pick-and-place machine. In contrast, this application adopts a second material storage unit that is detachably connected to the first material storage unit. This allows the feed tower structure to occupy only one workstation, so that the feed tower structure can still supply material to the pick-and-place machine when replenishing material to the feed tower structure.

[0038] Furthermore, taking the first storage chamber 110 having 3 storage positions and the second storage chamber 210 having 2 storage positions as an example, the usage scenario of the material tower structure is described. During use, the first storage chamber 110 has 3 material trays 300 containing material, and the second storage chamber 210 has 2 material trays 300 containing material. Further, the material trays 300 in the first storage chamber 110 are removed by the picking arm of the placement machine. After the material trays 300 are used, the picking arm returns the empty material trays 300 to the first storage chamber 110. Then, the material trays 300 containing material in the first storage chamber 110 are removed for use. At this time, the first storage chamber 110 has one empty material tray 300, one empty storage position, and one material tray 300. The picking arm then removes the material trays 300 containing material from the second storage chamber 210. The material tray 300 in the storage chamber 210 is placed into an empty storage position in the first storage chamber 110. There will be an empty storage position in the second storage chamber 210. Then, the empty material tray 300 in the first storage chamber 110 is placed into the empty storage position in the second storage chamber 210. This cycle is repeated. When the second storage chamber 210 is empty, the second storage section 200 is removed from the first storage section 100 and replaced with a second storage section 200 containing material. In this way, during the process of replenishing the material tower structure when replacing the second storage section 200, the first storage section 100 always contains material, which can meet the material supply needs of the material tower structure to the chip placement station. This solves the problem in the prior art that the material tower structure cannot supply material to the chip placement machine during replenishment.

[0039] In one embodiment, referring to Figures 1 and 2, the first storage section 100 has a top surface 140, and the second storage section 200 is detachably connected to the top surface 140 of the first storage section 100. This allows the material tower structure to have a larger dimension in the height direction, avoiding the occupation of horizontal space in the pick-and-place machine. However, this design is not limited to this. In some embodiments, the first storage section 100 has a side surface. In this case, the second storage section 200 is detachably connected to the side surface of the first storage section 100. In this case, the detachable structure is configured as a connecting platform mounted on the side surface of the first storage section 100, and the second storage section 200 can be placed on the connecting platform.

[0040] In one embodiment, referring to FIG1, the first storage chamber 110 is provided with a first opening 111 for the feeding tray 300 to enter and exit, and the second storage chamber 210 is provided with a second opening 211 for the feeding tray 300 to enter and exit. The first opening 111 and the second opening 211 are both arranged facing the same side. In this way, when the feeding trays 300 in the first storage chamber 110 and the second storage chamber 210 are rotated, it is convenient for the material handling arm to operate, so that the feeding tray 300 can enter from the first storage chamber 110 into the second storage chamber 210, or from the second storage chamber 210 into the first storage chamber 110.

[0041] In one embodiment, the first storage section 100 is positioned relative to the second storage section 200 at a first position; at the first position, the second storage section 200 is located on the top surface 140 of the first storage section 100, and the first cavity 111 and the second cavity 211 are both oriented towards the same side; the material tower structure includes a positioning structure for positioning the second storage section 200 at the first position. Further, in some embodiments, the positioning structure includes a triangular positioning pin and a positioning hole, wherein the positioning... One of the pin and the positioning hole is located on the top surface 140 of the first storage section 100, and the other is located on the second storage section 200. When the second storage section 200 is located on the top surface 140 of the first storage section 100, the positioning pin can be inserted into the positioning hole so that the second storage section 200 is in the first position. It can be understood that, due to the special nature of the triangular structure, the positioning pin and the positioning hole have a guiding function for positioning during use. When the first cavity 111 and the second cavity 211 are both facing the same side, the positioning pin can be inserted into the positioning hole.

[0042] Of course, in some embodiments, to detect that the second storage section is installed in the first position, a sensor can also be installed in the positioning hole. When the positioning pin is inserted into the positioning hole, the sensor is triggered, and the sensor sends a signal to the pick-and-place machine. The pick-and-place machine receives the signal and confirms that the second storage section is installed in the first position. The positioning hole is located on the top surface of the first storage section, and the sensor can be a contact sensor.

[0043] Furthermore, in some embodiments, the second storage section 200 is disposed on the top surface 140 of the first storage section 100. The pick-and-place machine is provided with a lifting plate (not shown in the figure) that can be raised and lowered. The lifting plate is used to restrict the material tower structure. It should be noted that multiple lifting plates are configured and disposed on the periphery of the material tower structure. When the second storage section 200 needs to be replaced, the lifting plate retracts. At this time, the lifting plate does not block the second storage section 200, and the user can remove the second storage section 200 from the first storage section 100. After the second storage section 200 is replaced, the lifting plate rises to block the second storage section 200.

[0044] In one embodiment, referring to FIG2, the first storage section 100 includes a first mounting frame formed by splicing multiple first splicing plates 120 and at least three first carrying plates 130 disposed within the first mounting frame. The first carrying plates 130 are used to place the feeding tray 300. It should be noted that the multiple first splicing plates 120 can be connected by screw fastening, and the first carrying plates 130 are installed on the first mounting frame by screw fastening. This enables the first storage section 100 to be configured as a modular structure, which facilitates the assembly of the first storage section 100.

[0045] Furthermore, in some embodiments, referring to FIG3, the second storage section 200 includes a second mounting frame formed by splicing multiple second splicing plates 220 and two second carrying plates 230 disposed within the second mounting frame. The second carrying plates 230 are used to place the feeding tray 300. It should be noted that the multiple second splicing plates 220 can be connected by screw fastening, and the second carrying plates 230 are installed on the second mounting frame by screw fastening. This enables the second storage section 200 to be configured as a modular structure, which facilitates the assembly of the second storage section 200.

[0046] In one embodiment, referring to FIG3, the second storage section 200 is provided with a handle 240. The handle 240 is provided to facilitate the replacement of the second storage section 200, wherein the handle 240 is located on the side of the second storage section 200 away from the first storage section 100. However, this design is not limited to this. In some embodiments, the handle 240 may also be located in other positions, such as on both sides of the second storage section 200.

[0047] In one embodiment, referring to FIG4, the storage positions in the first storage chamber 110 are stacked. In another embodiment, the storage positions in the second storage chamber 210 are stacked, which allows for greater application of the material tower structure in the vertical direction, reduces the horizontal space occupied by the material tower structure, avoids occupying the horizontal space in the pick-and-place machine, and facilitates compact placement design. It is understood that when the storage positions are stacked, the carrier trays are also stacked. To ensure better stability between adjacent carrier trays, a support column 400 is connected between adjacent carrier trays, wherein the support column 400 is located away from the cavity opening.

[0048] In one embodiment, referring to FIG1, the first storage cavity 110 has 12 storage positions and the second storage cavity 210 has 6 storage positions. However, the design is not limited to this. In some embodiments, the first storage cavity 110 may also have 10 storage positions and the second storage cavity 210 may have 8 storage positions.

[0049] This utility model also proposes a pick-and-place machine, which includes a feed tower structure. The specific structure of the feed tower structure is as described in the above embodiments.
