Description

Technical Field

[0001] This utility model relates to the field of chip mounter technology, and in particular to a chip mounter and its feeder hopper. Background Technology

[0002] The feeder of a pick-and-place machine is a key component in the surface mount technology (SMT) production line, mainly used to transport electronic components (such as resistors, capacitors, ICs, etc.) wound into a reel.

[0003] In existing technologies, feeder feeding systems typically employ a design where a material box carries the material trays. The material box is installed below the feeder and stores multiple trays for feeding the feeder. However, the existing material box design can only accommodate a single type of tray. When switching to different tray sizes during production, it is necessary to replace or add a dedicated material box of the corresponding size, thus the compatibility of the material boxes needs to be improved.

Therefore, the above terms should not be construed as limiting the actual number of elements of the present invention.

[0027] 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.

[0028] refer to Figure 1 and Figure 2 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.

[0029] 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.

[0030] refer to Figure 1 , Figure 2 and Figure 3The feeder cassette 10 includes a body 11 and partitions 12. The body 11 has multiple slots 111 arranged side-by-side and spaced apart. Multiple partitions 12 are detachably disposed within the slots 111, forming receiving slots 121 between adjacent partitions 12 for accommodating trays 20. The feeder cassette 10 allows for the replacement of trays 20 of different specifications during production. By removing or installing partitions 12 according to the required tray size, the distance between adjacent partitions 12 is changed, thereby altering the size of the receiving slots 121 to accommodate trays 20 of the corresponding size. This structure allows the trays 20 of the corresponding size to be placed within the feeder cassette 10. This structure adapts to different tray sizes without requiring replacement of the feeder cassette 10, eliminating the need for separate feeder cassettes for each tray size, thus improving the compatibility of the feeder cassette 10 and reducing production costs.

[0031] Continue to refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the slots 111 are evenly spaced on the housing 11. For example... Figure 1 As shown, multiple slots 111 are evenly spaced along the width of the feeder box. When all slots 111 are fitted with partitions 12, the resulting receiving slots 121 are also evenly distributed within the feeder box 10. For example, in... Figure 1 In the illustrated embodiment, all slots 111 are equipped with partitions 12, with a spacing of approximately 32mm between adjacent partitions 12. When it is necessary to replace the trays 20 with different specifications, such as larger trays 20, production personnel can adaptively remove some partitions 12 according to the thickness or axial dimension of the tray 20, thereby increasing the width of the receiving grooves 121 between adjacent partitions 12, allowing the larger trays 20 to be smoothly placed into the feeder box 10. For feeder boxes 10 with some partitions 12 removed, when it is necessary to accommodate smaller trays 20, the partitions 12 can be reinstalled in the box body 11, narrowing the spacing between adjacent partitions 12 to accommodate the smaller trays 20. It is understood that the denser the distribution of slots 111 in the feeder box 10, the more precise the adjustment of the dimensions of the receiving grooves 121, and the better the compatibility of the feeder box 10.

[0032] Specifically, the box body 11 includes a base plate 112, a first mounting plate 113 and a second mounting plate 114 connected to opposite ends of the base plate 112, and a baffle 115 connected between the first mounting plate 113 and the second mounting plate 114. The baffle 115 is connected to the base plate 112 and has slots 111, with multiple slots 111 evenly arranged in the direction from the first mounting plate 113 to the second mounting plate 114. Figure 1As shown, the overall shape of the box 11 can be approximately rectangular. The first mounting plate 113 and the second mounting plate 114 include mounting holes (not shown) that are arranged opposite each other. The base plate 112 and the baffle 115 may include threaded holes (not shown) that match the mounting holes. When the base plate 112 and the baffle 115 are installed, the base plate 112 and the baffle 115 are positioned between the first mounting plate 113 and the second mounting plate 114, with the baffle 115 positioned on the side of the base plate 112 facing away from the ground. After matching the threaded holes of the base plate 112 and the baffle 115 with the mounting holes of the first mounting plate 113 and the second mounting plate 114, a detachable connection can be achieved using threaded fasteners such as screws.

[0033] For example, the diameter of the second type of tray 21 is about 175 mm, and the diameter of the first type of tray 22 is about 420 mm, that is, the diameter of the second type of tray 21 is smaller than that of the first type of tray 22. When the second type of tray 21 is placed into the feeder box 10, the receiving groove 121 that accommodates the second type of tray 21, together with its two adjacent partitions 12 and bottom plate 112, supports and limits the second type of tray 21; when some partitions 12 are removed and the first type of tray 22 is placed in, the receiving groove 121 that accommodates the first type of tray 22, together with its two adjacent partitions 12, bottom plate 112 and baffle 115, supports and limits the first type of tray 22.

[0034] refer to Figure 1 and Figure 2 In some embodiments, the first mounting plate 113 includes a first connecting portion 1131, and the second mounting plate 114 includes a second connecting portion 1141. The first connecting portion 1131 and the second connecting portion 1141 are disposed on the same side as the baffle 115. Exemplarily, the first connecting portion 1131 has a first connecting hole 11311, and the second connecting portion 1141 has a second connecting hole 11411. The feeder cassette 10 can be fixed to the body of the pick-and-place machine after matching the corresponding positions of the first connecting hole 11311 of the first connecting portion 1131 and the second connecting hole 11411 of the second connecting portion 1141. Of course, in some embodiments, the feeder cassette 10 can also be mounted on other auxiliary structures, such as a feeder cart, through the first connecting hole 11311 of the first connecting portion 1131 and the second connecting hole 11411 of the second connecting portion 1141, and the feeder cart is then docked to the body of the pick-and-place machine.

[0035] refer to Figure 1 and Figure 2In some embodiments, the feeder box 10 includes a first rotating sleeve 13 disposed between a first mounting plate 113 and a second mounting plate 114. The first rotating sleeve 13 is located on the side of the base plate 112 away from the baffle 115 and is used for rolling contact with a first type of tray 22 protruding from the receiving groove 121. Specifically, the first rotating sleeve 13 includes a first connecting member 131 and a second connecting member 132 disposed opposite to each other, and a multi-section rotating cylinder 133 disposed between the first connecting member 131 and the second connecting member 132. A mandrel (not shown) may be connected between the first connecting member 131 and the second connecting member 132, and the multi-section rotating cylinder 133 is rotatably sleeved on the mandrel. One end of the first connecting member 131 is connected to the first mounting plate 113, and the opposite end is connected to one end of the mandrel. One end of the second connecting member 132 is connected to the second mounting plate 114, and the opposite end is connected to the other end of the mandrel. The first connector 131 is connected to one side of the first mounting plate 113 and is connected to the first mounting plate 113 through two connecting holes and corresponding threaded fasteners. The second connector 132 is connected to one side of the second mounting plate 114 and is connected to the second mounting plate 114 through two connecting holes and corresponding threaded fasteners, providing stable support for the rotating drum 1163.

[0036] Furthermore, the feeder cassette 10 includes a second rotating sleeve 14 disposed between the first mounting plate 113 and the second mounting plate 114 and on the same side as the first rotating sleeve 13. The axial direction of the second rotating sleeve 14 is parallel to the axial direction of the first rotating sleeve 13, and it is closer to the baffle 115 than the first rotating sleeve 13. The second rotating sleeve 14 is used to roll into contact with the second type of tray 21 housed in the receiving groove 121. For example, when the feeder installed on the pick-and-place machine is working, the second type of tray 21 placed in the feeder cassette 10 supplies the feeder with a strip containing electronic components. As the feeder drives the strip, the second type of tray 21 also rotates to release the strip wound on the second type of tray 21. The second rotating sleeve 14 then rotates in the opposite direction to the second type of tray 21, confining the second type of tray 21 within the receiving groove 121, while reducing the frictional resistance between the feeder cassette 10 and the second type of tray 21 through rolling friction. The structure of the second rotating sleeve 14 can be similar to that of the first rotating sleeve 13, and will not be described in detail here.

[0037] Furthermore, the feeder hopper 10 includes a third rotating sleeve 15 disposed between the first mounting plate 113 and the second mounting plate 114 and on the same side as the baffle 115. The axial direction of the third rotating sleeve 15 is parallel to the axial direction of the first rotating sleeve 13, and it is used for rolling contact with the first type of tray 22 protruding from the receiving groove 121. In other words, the first rotating sleeve 13 and the third rotating sleeve 15 respectively contact... Figure 1The first type of material tray 22 is shown. When the first type of material tray 22 rotates, the first rotating sleeve 13 and the third rotating sleeve 15 cooperate to restrict the rolling of the first type of material tray 22, prevent the first type of material tray 22 from displacing, and at the same time reduce the frictional resistance between the feeder box 10 and the first type of material tray 22. The third rotating sleeve 15 can adopt a structure similar to that of the first rotating sleeve 13, that is, it is provided with a mandrel and a multi-section rotating cylinder sleeved on the mandrel.

[0038] It is understandable that the rolling contact between the first rotating sleeve 13 and the third rotating sleeve 15 and the first type of tray 22 applies to a specific size of the first type of tray 22. This size can be considered a limit size. When the radial dimension of the first type of tray 22 is smaller than this limit size, it is sufficient for the first type of tray 22 to roll into contact with the first rotating sleeve 13 to reduce frictional resistance. The rolling contact between the first type of tray 22 and the third rotating sleeve 15 is not necessary. In this embodiment, when the feeder box 10 is placed horizontally, the height of the spindle of the third rotating sleeve 15 from the horizontal ground is greater than the height of the spindle of the first rotating sleeve 13 from the same horizontal ground, so that the first type of tray 22 can abut against the first rotating sleeve 13 under the action of gravity.

[0039] refer to Figure 1 and Figure 2 In some embodiments, the feeder box 10 includes a push rod 16 spanning between a first mounting plate 113 and a second mounting plate 114. Specifically, 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 113, one end of the second support member 162 is connected to the second mounting plate 114, 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 112.

[0040] Furthermore, the first mounting plate 113 and the second mounting plate 114 are respectively provided with handle through holes 11a. For example... Figure 1 As shown, the handle through hole 11a can be rectangular, which makes it easy for installers to move the feeder box 10 through the handle through hole 11a.

[0041] refer to Figure 1 and Figure 2 In some embodiments, the feeder cassette 10 may further include a waste cassette 17, which is disposed on the side of the base plate 112 opposite to the partition plate 12. When the feeder installed on the pick-and-place machine is working, 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 17 from the reserved channel of the pick-and-place machine and is collected in the waste cassette 17, which facilitates the recycling of the tape and prevents environmental pollution.

[0042] 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.

[0043] 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.
