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.

[0028] 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.

[0029] refer to Figure 1 This utility model discloses a feeder cassette 10, which can be applied to a pick-and-place machine. A pick-and-place machine is an automated device used in electronic manufacturing. Its core function is to precisely mount surface mount components onto designated positions on a substrate using a high-precision, high-efficiency mounting process. In some embodiments, the surface mount components for mounting are disposed on a flexible tape, which is wound into a disc to form a tray 20, with the surface mount components distributed along the tape.

[0030] The pick-and-place machine may include a machine body and the feeder cassette 10 described above, with the feeder cassette 10 detachably mounted on the machine body. When the feeder is installed in the pick-and-place machine and is operating normally, the feeder cassette 10 is used to limit and support the tray 20, providing a stable feed of material to the feeder, which then guides the material to the location of the mounting head, facilitating the mounting head to pick up surface mount components.

[0031] refer to Figure 1 The feeder tray 10 includes a support assembly 11, a hanging rod 12, and a hook 13. The support assembly 11 has multiple accommodating slots 111 arranged side-by-side and spaced apart. The accommodating slots 111 are used to hold a first type of tray 21. The hanging rod 12 is connected to the support assembly 11 and spans across the accommodating slots 111. The hook 13 is used to suspend the tray from the hanging rod 12 and can hold a second type of tray 22, so that the second type of tray 22 can be rotatably attached to the support assembly 11. The diameter of the second type of tray 22 is larger than that of the first type of tray 21. The feeder box 10 described above has a relatively small diameter first type of tray 21 that can be placed in the receiving slot 111. For the relatively large diameter second type of tray 22, the second type of tray 22 can be limited in the feeder box 10 by the cooperation of the support component 11, the hanging rod 12 and the hook 13, so as to realize the normal feeding of the second type of tray 22. There is no need to replace and configure the corresponding large-size special feeder box 10, which improves the compatibility of the feeder box 10 and reduces the production cost.

[0032] Furthermore, the support assembly 11 includes a housing 112 and a plurality of partitions 113 connected to the housing 112, with adjacent partitions 113 and the housing 112 enclosing a receiving groove 111. When the size of the tray 20 can be accommodated within the receiving groove 111 of the feeder cassette 10, i.e., when it is a first type of tray 21, the first type of tray 21 can be directly placed into the receiving groove 111 of the feeder cassette 10. Figure 1 As shown, the first type of tray 21 can be supported and limited by the receiving groove 111 provided by the support component 11; when the tray 20 is too large to exceed the receiving size of the receiving groove 111, i.e. the second type of tray 22, the second type of tray 22 can be hung by the support component 11, hanging rod 12 and hanging rod 12 provided by the feeder box 10, so that production personnel can choose different placement methods according to the different sizes of trays, thereby improving the compatibility and ease of use of the feeder box 10.

[0033] Also refer to Figure 1 , Figure 2 and Figure 3 The box body 112 has multiple spaced slots 1121, and partitions 113 are detachably disposed in the slots 1121 so that the width of the receiving slots 111 is variable. Furthermore, as... Figure 1 As shown, slots 1121 are evenly spaced along the width of the feeder box 112. For a feeder box 10 with a diameter larger than the first type of tray 21 and smaller than the second type of tray 22, such as the third type of tray 23, some partitions 113 can be appropriately removed according to the thickness or axial dimension of the third type of tray 23. This increases the width of the receiving groove 111 between adjacent partitions 113, allowing the large-sized third type of tray 23 to be smoothly placed into the feeder box 10. When it is necessary to place a small-sized first type of tray 21, the partitions 113 can be reinstalled in the box 112, narrowing the distance between adjacent partitions 113 to accommodate the first type of tray 21. It can be understood that the denser the distribution of slots 1121 in the feeder box 10, the more precise the adjustment of the size of the receiving groove 111, and the better the compatibility of the feeder box 10. In some embodiments, the diameter of the first type of tray 21 may be less than 175 mm, the diameter of the second type of tray 22 may be greater than 420 mm, and the diameter of the third type of tray 23 may be greater than 175 mm and less than 420 mm.

[0034] Specifically, the box body 112 includes a base plate 1122, a first mounting plate 1123 and a second mounting plate 1124 connected to opposite ends of the base plate 1122, and a baffle 1125 connected between the first mounting plate 1123 and the second mounting plate 1124. The baffle 1125 is connected to the base plate 1122 and has a slot 1121. Multiple slots 1121 are evenly arranged in the direction from the first mounting plate 1123 to the second mounting plate 1124. In some embodiments, the base plate 1122 also has a groove corresponding to the slot 1121 of the baffle 1125. The groove of the base plate 1122 and the slot 1121 of the baffle 1125 cooperate to engage adjacent sides of the partition 113, restricting the movement of the partition 113 and reliably positioning it within the box body 112. Figure 1 As shown, the overall shape of the box 112 can be approximately rectangular. The base plate 1122, baffle 1125, first mounting plate 1123, and second mounting plate 1124 can be detachably connected via threaded fasteners. For example, the base plate 1122 and baffle 1125 are positioned between the first mounting plate 1123 and the second mounting plate 1124, with the baffle 1125 positioned on the side of the base plate 1122 facing away from the ground. One end of the base plate 1122 and baffle 1125 is detachably connected to the first mounting plate 1123 via threaded fasteners, and the opposite end of the base plate 1122 and baffle 1125 is detachably connected to the second mounting plate 1124 via threaded fasteners. This modular design simplifies the processing flow of the base plate 1122, baffle 1125, first mounting plate 1123, and second mounting plate 1124, improving the assembly efficiency of the feeder box and reducing the production cost of the feeder box 10.

[0035] refer to Figure 1 In some embodiments, the feeder cartridge 10 is detachably connected to the pick-and-place machine via the housing 112 of the support assembly 11. The first mounting plate 1123 of the housing 112 includes a first connecting portion 11231, and the second mounting plate 1124 of the housing 112 includes a second connecting portion 11241. The first connecting portion 11231 and the second connecting portion 11241 are disposed on the same side as the baffle 1125. Exemplarily, the first connecting portion 11231 and the second connecting portion 11241 each have a connecting hole 1123a. The feeder cartridge 10 can be matched with the corresponding position of the pick-and-place machine body through the connecting holes 1123a of the first connecting portion 11231 and the connecting holes 1123a of the second connecting portion 11241, thus fixing the feeder cartridge 10 to the pick-and-place machine body. Of course, in some embodiments, the feeder box 10 can also be installed on other auxiliary structures, such as feeder carts, through the connection holes 1123a of the first connection part 1131 and the connection holes 1123a of the second connection part 1141, and the feeder cart can then be docked to the body of the pick and place machine.

[0036] refer to Figure 1In some embodiments, the hanging rod 12 is disposed between the first mounting plate 1123 and the second mounting plate 1124, and is located on the side away from the baffle 1125.

[0037] refer to Figure 1 and Figure 2 The support assembly 11 includes a first rotating sleeve 114 disposed on the housing 112. The first rotating sleeve 114 is used to overlap the second type of material tray 22 and to roll in contact with the second type of material tray 22. Specifically, as shown... Figure 1 As shown, the axis of the first rotating sleeve 114 is parallel to the hanging rod 12. The first rotating sleeve 114 includes a first fixing member 1141 and a second fixing member 1142 arranged opposite to each other, and a multi-section rotating cylinder 1143 disposed between the first fixing member 1141 and the second fixing member 1142. A spindle (not shown) can be connected between the first connecting member 1161 and the second connecting member 1162, and the multi-section rotating cylinder 1163 is rotatably sleeved on the spindle. One end of the first fixing member 1141 is connected to the first mounting plate 1123, and the opposite end is connected to one end of the spindle. One end of the second fixing member 1142 is connected to the second mounting plate 1124, and the opposite end is connected to the other end of the spindle. The first fixing member 1141 can be detachably connected to the first mounting plate 1123 by threaded fasteners to facilitate the assembly and fixation of the first fixing member 1141 and the first mounting plate 1123. The second fastener 1142 can be detachably connected to the second mounting plate 1124 via threaded fasteners to facilitate the assembly and fixation of the second fastener 1142 and the second mounting plate 1124, and to provide stable support for the rotating sleeve 1143.

[0038] like Figure 1 As shown, when the second type of tray 22 is positioned within the feeder cassette 10, the second type of tray 22 is held by the hook 13. One end of the hook 13 is suspended from the hanging rod 12, and the other end of the hook 13 can be inserted into the central through hole of the second type of tray 22 through a rotating shaft, thereby achieving a rotational engagement between the second type of tray and the hook. The second type of tray 22 is also in contact with the first rotating sleeve 114. When the feeder installed on the pick-and-place machine is working normally, the second type of tray 22, located in the feeder cassette 10, supplies the feeder with a tape containing electronic components. As the feeder drives the tape, the second type of tray 22 rotates due to the feeder's movement, releasing the tape wound on the second type of tray 22. The first rotating sleeve 114 then rotates in the opposite direction to the second type of tray 22, reducing the frictional resistance between the support assembly 11 and the second type of tray 22 through rolling friction, thus achieving smooth material feeding.

[0039] Furthermore, the support assembly 11 includes a second rotating sleeve 115 disposed on the housing 112 and on the same side as the first rotating sleeve 114. The axial direction of the second rotating sleeve 115 is parallel to the axial direction of the first rotating sleeve 114, and it is closer to the slot 1121 than the first rotating sleeve 114. The second rotating sleeve 115 is used for rolling contact with the first type of tray 21. The structure of the second rotating sleeve 115 can be similar to that of the first rotating sleeve 114. The second rotating sleeve 115 is disposed between the first mounting plate 1123 and the second mounting plate 1124. When the feeder installed on the pick-and-place machine is working normally, the first type of tray 21 placed in the feeder tray 10 will supply the feeder with the tape containing electronic components. As the feeder drives the tape, the first type of tray 21 will also rotate to release the tape wound on the first type of tray 21. The second rotating sleeve 115 will rotate in the opposite direction to the first type of tray 21, confining the first type of tray 21 in the receiving groove 121. At the same time, the frictional resistance between the support assembly 11 and the first type of tray 21 is reduced by rolling friction.

[0040] Also refer to Figure 1 and Figure 2 In some embodiments, the support assembly 11 includes a third rotating sleeve 116, which is disposed on the side of the housing 112 away from the first rotating sleeve 114. The axial direction of the third rotating sleeve 116 is parallel to the axial direction of the first rotating sleeve 114, and it is used for rolling contact with the third type of tray 23 protruding from the receiving groove 111. The structure of the third rotating sleeve 116 can be similar to that of the first rotating sleeve 114. When the third type of tray 23 is placed in the receiving groove 111 of the feeder cassette 10, the first rotating sleeve 114 and the third rotating sleeve 116 respectively support one side of the third type of tray 23. When the third type of tray 23 rotates during feeding, the first rotating sleeve 114 and the third rotating sleeve 116 cooperate to restrict the rolling of the third type of tray 23, prevent the third type of tray 23 from displacing, and reduce the frictional resistance between the third type of tray 23 and the support assembly 11.

[0041] It is understandable that the rolling contact between the first rotating sleeve 114 and the third rotating sleeve 116 and the third type of tray 23 applies to a specific size of the third type of tray 23. This size can be considered a limit size. When the radial dimension of the third type of tray 23 is smaller than this limit size, it is sufficient for the third type of tray 23 to roll contact with the first rotating sleeve 114 to reduce frictional resistance. The rolling contact between the third type of tray 23 and the third rotating sleeve 116 is not necessary. In this embodiment, when the feeder box 10 is placed horizontally, the height of the spindle of the third rotating sleeve 116 from the horizontal ground is greater than the height of the spindle of the first rotating sleeve 114 from the same horizontal ground, so that the third type of tray 23 can abut against the first rotating sleeve 114 under the action of gravity.

[0042] Continue to refer to Figure 1 and Figure 2 In some embodiments, the feeder cassette 10 may further include a waste cassette 14, which is located on the side of the cassette body 112 opposite to the hanging rod 12. When the feeder installed on the pick-and-place machine is working normally, the tray 20 is placed in the feeder cassette 10, and the tray 20 provides the feeder with tape. After the electronic components on the tape are picked up by the nozzle of the pick-and-place machine, the remaining tape reaches the waste cassette 14 from the reserved channel of the pick-and-place machine and is collected in the waste cassette 14, which facilitates the recycling of the tape and prevents environmental pollution.

[0043] Continue to refer to Figure 1 and Figure 2 In some embodiments, the feeder box 10 includes handle through holes 15 respectively disposed on the first mounting plate 1123 and the second mounting plate 1124. For example... Figure 2 As shown, the handle through hole 15 can be rectangular, which makes it easy for installers to move the feeder box 10 through the handle through hole 15.

[0044] Furthermore, the feeder box 10 may include a push rod 16 disposed between the first mounting plate 1123 and the second mounting plate 1124. Specifically, as shown... Figure 1 As shown, the push rod 16 includes a first support member 161 and a second support member 162 disposed opposite to each other, and a rod portion 163 disposed between the first support member 161 and the second support member 162. One end of the first support member 161 is connected to the first mounting plate 1123, one end of the second support member 162 is connected to the second mounting plate 1124, and the rod portion 163 is connected to the ends of the first support member 161 and the second support member 162 away from the base plate 1122. The push rod 16 is designed to allow the operator to directly push the mechanism carrying the feeder box 10, such as the feeder cart, to move when moving the feeder box 10.

[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.
