Description

Technical Field

[0001] This utility model relates to the field of flexible board production technology, and in particular to a novel material cart. Background Technology

[0002] In the production process of FPC (Flexible-Printed-Circuit) products, SMT (Surface Mount Technology) pick-and-place machines are used to print and mount electronic components onto the FPC. Furthermore, to achieve high-speed continuous feeding, reduce manual intervention, and ensure uninterrupted operation of the SMT pick-and-place machine, a reel is typically used to continuously feed material tape carrying electronic components such as capacitors, resistors, and chips (i.e., mounting components). During the mounting process, the material tape on the reel is transported to the SMT pick-and-place machine via a feeding device. The SMT pick-and-place machine precisely picks up the mounting components from the tape using its placement head and prints and mounts the components onto the FPC.

[0003] Furthermore, in order to achieve uninterrupted production of SMT pick and place machines, material carts are used to store the reels of supply tapes. In traditional technology, conventional material carts can only store one type of reel, which cannot adapt to different types of material supply needs; in addition, the storage racks on conventional material carts cannot be moved, which cannot meet the needs of automatic reel loading and unloading. Utility Model Content

[0004] This utility model provides a new type of material cart that can solve the technical problem that the material cart in the traditional technology cannot adapt to the material supply needs of different types of reels, nor can it adapt to the needs of automatic reel loading and unloading.

[0005] To solve the above-mentioned technical problems, this utility model provides a novel material cart, comprising:

[0006] The chassis includes a main frame open on one side and top, and at least two storage plates disposed on the main frame, each storage plate having at least one storage station; and

[0007] The storage compartment includes multiple storage racks arranged side-by-side at one of the storage stations; each storage rack includes a rack base slidably mounted on the storage plate, a main frame body mounted on the rack base body and having a chuck groove for holding a reel, and a material pull hook located on the side of the main frame body, the material pull hook being used to cooperate with external material handling equipment.

[0008] Optionally, a storage groove is provided on one of the top surface of the storage plate and the bottom surface of the storage rack base, and a storage rail is provided on the other surface, with the storage rail slidably engaged in the storage groove.

[0009] Optionally, the storage compartment includes an inner limit block located inside the storage station and an outer limit block located outside the storage station.

[0010] The outer limiting block is provided with the storage groove, the bottom surface of the disk frame base is provided with the storage rail, and each end of the disk frame base is provided with a limiting baffle, which is respectively positioned on both sides of the storage groove.

[0011] Optionally, the inner limiting block is positioned inside the plurality of storage racks, and the outer limiting block has a plurality of storage slots arranged side by side, with the plurality of storage racks slidingly engaged in the plurality of storage slots in a corresponding manner.

[0012] Optionally, the inner limiting block is provided with a positioning slot on its side, and the limiting baffle at one end of the plate base cooperates with the positioning slot.

[0013] Optionally, each side of the chuck groove of the main frame is provided with an elastic clamp for clamping the coil into the chuck groove from both sides.

[0014] Optionally, the material hook includes an L-shaped folding plate protruding from the side of the top of the main frame.

[0015] Optionally, a connecting protrusion is provided on each side of the bottom of the main frame, and a connecting block with a connecting slot is provided at one end of the top surface of the tray base. One of the connecting protrusions of the main frame is engaged in the connecting slot of the connecting block, and the other connecting protrusion is detachably provided on the top surface of the tray base.

[0016] Optionally, the storage board includes a storage board frame disposed on the main frame and a storage main board disposed on the storage board frame, and the storage station is disposed on the storage main board.

[0017] Optionally, the storage stations on the multi-layer storage boards on the main frame are at least partially staggered.

[0018] The beneficial effects of the technical solution provided by this utility model include:

[0019] By setting multiple storage plates on the main frame of the vehicle frame, and setting at least one storage station on each storage plate, multiple storage stations can be formed on the vehicle frame (each storage station can be equipped with a storage compartment), so that various types of reels can be stored on the vehicle frame (the storage compartment at each storage station can be used to store one type of reel), thus meeting the material supply needs of different types of material strips (each type of reel can be wound with one type of material strip).

[0020] Furthermore, by sliding multiple storage racks at each storage station, each storage rack can hold one reel. Further, by sliding the rack base of each storage rack onto the storage plate, the reel, or an empty main frame, can slide from the inside of the main frame through its side opening to the outside, allowing external material handling equipment to retrieve the reel from the chuck slot or place it in the chuck slot. During reel handling, external material handling equipment can automatically pull or push the hooks on the side of the main frame to pull the storage rack out of the frame or push it back in. By sliding the storage rack and providing push-pull hooks, it can be coordinated with external material handling equipment to meet the needs of automatic reel handling. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] like Figures 1 to 3 As shown, this utility model proposes a novel material cart 10, including a frame 100 and multiple storage compartments 200 disposed on the frame 100. The frame 100 provides support for the multiple storage compartments 200, and the multiple storage compartments 200 can store various types of reels 20, which can simultaneously meet the material supply needs of different types of material strips.

[0032] Specifically, such as Figure 3As shown, the frame 100 may include a main frame 110 and at least two layers of storage plates 120 disposed on the main frame 110, with storage compartments 200 disposed on the storage plates 120. Furthermore, one side and the top of the main frame 110 are open, and each storage plate 120 has at least one storage station 130, with a storage compartment 200 disposed at each storage station 130. By providing a storage compartment 200 at each storage station 130 on the multiple storage plates 120 of the main frame 110, each storage compartment 200 can be used to store one type of coil 20, thereby allowing multiple types of coil 20 to be stored on the frame 100. By setting multiple storage plates 120 on the main frame 110 of the chassis 100, and setting at least one storage station 130 on each storage plate 120, multiple storage stations 130 can be formed on the chassis 100 (each storage station 130 can be equipped with a storage compartment 200), so that various types of reels 20 can be stored on the chassis 100 (the storage compartment 200 at each storage station 130 can be used to store one type of reel 20), thus meeting the material supply needs of different types of material strips (each type of reel 20 can be wound with one type of material strip).

[0033] Moreover, such as Figures 1 to 2 As shown, by opening one side of the main frame 110 while surrounding it with the other sides, the reel 20 can be picked up and put into the storage compartment 200 through the open side. Furthermore, by opening the top surface of the main frame 110, the material strip on the reel 20 in the storage compartment 200 can be pulled out of the material cart and supplied to the SMT placement machine through the open top surface. Further, the storage compartment 200 is movably mounted at the storage station 130 on the storage plate 120, facilitating its movement. This allows the storage compartment 200 and its stored reel 20 to be moved through the open side of the main frame 110 to the outside of the material cart, enabling automatic picking up of the reel 20 from the storage compartment 200 or automatic storage of the reel 20 in the storage compartment 200 by external material handling equipment.

[0034] More specifically, such as Figure 3 As shown, each storage compartment 200 may include multiple storage racks 202 movably arranged side-by-side at a storage station 130. By slidably arranging multiple storage racks 202 at each storage station 130, each storage rack 202 can be used to store a reel 20. Moreover, each storage rack 202 may include a rack base 210 slidably disposed on a storage plate 120, a main frame 220 disposed on the rack base 210 and having a chuck groove 222 for holding the reel 20, and a material pull hook 230 disposed on the side of the main frame 220 for cooperating with external material handling equipment.

[0035] By sliding the tray base 210 of each tray rack 202 onto the tray plate 120, the coil 20 locked in the chuck groove 222 of the main frame 220, or an empty main frame 220, can slide from the inside of the main frame 110 through its side opening to the outside of the main frame 110 along with the tray base 210. This facilitates external material handling equipment to pick up the coil 20 from the chuck groove 222 of the main frame 220 or to place the coil 20 into the chuck groove 222 of the main frame 220. Moreover, during the process of picking up and placing the coil 20, the external material handling equipment can automatically pull or push the material hook 230 on the side of the main frame 220 to pull the tray rack 202 out of the frame 100 or push the tray rack 202 back into the frame 100. By sliding the storage rack 202 and installing a push-pull material hook 230 on it, it can be used with external material handling equipment to meet the needs of automatic material handling of the roll 20.

[0036] In addition, such as Figures 1 to 3 As shown, the frame 100 may include a roller structure 140 located at the bottom of the main frame 110, which facilitates the movement of the entire material cart. Furthermore, the frame 100 may include a wheel drive structure connected to the roller structure 140, which drives the roller structure 140 to move the frame 100 automatically. Additionally, the main frame 110 may include a rectangular main frame and side frame plates surrounding multiple sides of the main frame, enclosing multiple sides of the main frame while leaving one side and the top of the main frame open. Moreover, the roller structure 140 may include multiple movable rollers located around the bottom of the main frame 110. A storage plate is provided on the bottom side of the main frame 110, which not only encloses the main frame 110 from the bottom but also serves to house a storage compartment 200 at the bottom of the main frame 110.

[0037] Moreover, such as Figures 4 to 6 As shown, each storage board 120 may include a storage board frame 123 disposed on the main frame 110, and a storage main board 124 disposed on the storage board frame 123, with the storage station 130 disposed on the storage main board 124. The storage board frame 123 may be disposed inside the main frame of the main frame 110 to provide support for the storage main board 124. Moreover, the storage board frame 123 may also be configured as part of the main frame (i.e., the storage main board 124 may be directly disposed on the main frame), or it may be disposed independently relative to the main frame.

[0038] In addition, such as Figures 1 to 3As shown, the storage stations 130 on the multi-layer storage plate 120 on the main frame 110 are at least partially staggered. By staggering some or all of the storage bins 200 on the multi-layer storage plate 120, it is not only convenient to arrange different types of storage bins 200 (such as large-sized storage bins 200 and small-sized storage bins 200) on the multi-layer storage plate 120, but also convenient for the reel 20 in the storage bin 200 to discharge the material strip by utilizing the gaps between the staggered storage bins 200. It is also convenient for the storage rack 202 of the storage bin 200 to move between the inner side (referring to the area enclosed by the main frame 110) and the outer side (referring to the area outside the main frame 110) of the main frame 110.

[0039] In this embodiment, as Figure 3 As shown, two storage plates 120 can be set on the main frame 110. Two storage stations 130 can be set on the bottom storage plate 120. One storage station 130 can be set with a storage compartment 200 composed of a large-sized storage rack 202 to store large-sized coil trolleys 20. The other storage station 130 can be set with a storage compartment 200 composed of a smaller-sized storage rack 202 to store small-sized coil trolleys 20. In addition, a storage station 130 can be set on the top storage plate 120. This storage station 130 can be set with a storage compartment 200 composed of a third-sized storage rack 202 to store a third-sized coil trolley 20. Furthermore, the top-level storage plate 120 may be partially positioned above the storage compartment 200 composed of smaller storage racks 202, while the top of the storage compartment 200 composed of larger storage racks 202 may be open, allowing the larger reel 20 to protrude above the top-level storage plate 120. Additionally, the rear side of the top-level storage plate 120 may have an opening, facilitating the output of the material strip from the reel 20 in the bottom-level storage compartment 200.

[0040] In addition, such as Figures 3 to 6 As shown, a storage groove 122 may be provided on one of the top surface of the storage plate 120 of the frame 100 and the bottom surface of the tray base 210 of the storage rack 202 of the storage compartment 200, and a storage rail 212 may be provided on the other. The storage rail 212 is slidably engaged in the storage groove 122. Both the storage groove 122 and the storage rail 212 extend from the inside of the main frame 110 to the side opening of the main frame 110, so that each storage rack 202 can slide from the inside of the main frame 110 through the side opening of the main frame 110 to the outside of the main frame 110, or in the opposite direction, so that after the storage rack 202 moves to the outside of the main frame, it is convenient to pick up or put down the material from the coil 20.

[0041] Furthermore, such as Figures 5 to 6As shown, each storage compartment 200 may include an inner limit block 240 located inside the storage station 130 and an outer limit block 250 located outside the storage station 130. The inner limit block 240 can limit the storage rack 202 from the inside to prevent the storage rack 202 from detaching from the storage station 130 when sliding inward; while the outer limit block 250 can limit the storage rack 202 from the outside to prevent the storage rack 202 from detaching from the storage station 130 when sliding outward.

[0042] Moreover, in this embodiment, such as Figure 6 As shown, a storage groove 122 can be formed on the outer limit stop 250, and a storage slide rail 212 is provided on the bottom surface of the disk rack base 210. A limit baffle 214 is provided at each end of the disk rack base 210, and the two limit baffles 214 are respectively positioned on both sides of the storage groove 122. This allows the storage groove 122 to be set on the outer limit stop 250 on the top surface of the storage plate 120, making the groove relatively simple and convenient. Furthermore, the storage slide rail 212 can protrude from the bottom surface of the disk rack base 210 of the storage rack 202, facilitating processing and installation. In addition, the limit baffles 214 provided on both sides of the bottom of the storage rack 202, in cooperation with the outer limit stop 250 and the inner limit stop 240, restrict the sliding position of the storage rack 202, preventing the storage rack 202 from dislodging.

[0043] Furthermore, such as Figure 6 As shown, the inner limit block 240 is positioned inside the multiple storage racks 202, and the outer limit block 250 has multiple storage grooves 122 arranged side by side. The multiple storage racks 202 are slidably engaged in the multiple storage grooves 122 in a corresponding manner. This allows for the installation of one inner limit block 240 and one outer limit block 250 at each storage station 130, simultaneously limiting the multiple storage racks 202 from both sides, making the setup simple and convenient. Furthermore, multiple storage grooves 122 can be provided on the outer limit block 250, allowing the base 210 of the multiple storage racks 202 in the storage compartment 200 to slide respectively in the multiple storage grooves 122. In addition, as needed, one or more inner limit blocks 240 and multiple outer limit blocks 250 may be provided at each storage station 130, such that each inner limit block 240 corresponds to at least one outer limit block 250 and at least one storage rack 202.

[0044] Furthermore, such as Figure 6As shown, the inner limit block 240 may have a positioning groove 242 on its side, and the limiting baffle 214 at one end of the disk holder base 210 corresponds to and cooperates with the positioning groove 242. This allows the disk holder 202 to slide inwards to abut against the inner limit block 240, where the limiting baffle 214 at the end of the disk holder 202 can be engaged in the positioning groove 242, circumferentially limiting the disk holder 202 and preventing it from shaking. Alternatively, a positioning protrusion may be provided on the side of the inner limit block 240, and a corresponding positioning groove may be provided on the limiting baffle 214 at the end of the disk holder 202, allowing for circumferential limiting through the positioning protrusion and positioning groove when the two are connected. Furthermore, an elastic buckle structure may be provided between the side of the inner limit block 240 and the limiting baffle 214 at the end of the disk holder 202 to buckle them together and achieve limiting of their movement.

[0045] In addition, such as Figure 7 As shown, the main frame 220 of the storage rack 202 has an elastic clip 224 on each side of the chuck groove 222, which is used to clamp the reel 20 into the chuck groove 222 from both sides. In the initial state, the elastic clips 224 on both sides can be in the open state under the action of their elasticity (that is, the upper part of the elastic clip 224 is in the open state), which makes it easy to insert the reel 20 into the chuck groove 222 from between the two elastic clips 224; when the reel 20 is placed in the chuck groove 222 of the storage rack 202, the lower part of the two elastic clips 224 can be squeezed, thereby overcoming their elastic force and causing the upper part to close, so that the reel 20 in the chuck groove 222 can be clamped and limited from the top side.

[0046] Moreover, such as Figure 7 As shown, a connecting protrusion 226 can be provided on each side of the bottom of the main frame 220. A connecting block 216 with a connecting slot protrudes from one end of the top surface of the tray base 210. One connecting protrusion 226 of the main frame 220 is engaged in the connecting slot of the connecting block 216, and the other connecting protrusion 226 is detachably provided on the top surface of the tray base 210. By engaging one end of the bottom of the main frame 220 with one side of the tray base 210 and detachably connecting the other end of the bottom of the main frame 220 to the other side of the tray base 210, the connection between the main frame 220 and the tray base 210 is simple and convenient.

[0047] Furthermore, the material pull hook 230 of the storage rack 202 may include an L-shaped folding plate protruding from the side of the top of the main frame 220. By setting the material pull hook 230 as an L-shaped folding plate, the structure is simple and it is convenient for external material handling equipment to push and pull it, thereby pulling the storage rack 202 out of or into the storage station 130.

[0048] The novel material cart 10 proposed by this utility model can store multiple reels 20 at the same time, which can meet the material supply needs of different types of material strips. The storage rack 202 for storing the reels 20 can be pushed, pulled and slid, so that it can move on both the inner and outer sides of the cart frame 100. This not only facilitates the picking and placing of the reels 20 on the storage rack 202, but also facilitates cooperation with external picking and placing equipment, which is conducive to realizing the automated replacement and maintenance of the reels 20.
