Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of production equipment for laminated products such as PCBs, and particularly relates to a double-inlet and double-outlet feeding rack. Background Technology
[0002] In the mass production of laminated products such as PCBs (Printed Circuit Boards), loading and unloading trolleys need to pick up and place materials from the unloading rack and transfer them to the press. The structural design of the unloading rack directly affects production efficiency and automation level. In existing technologies, unloading racks generally adopt a "single-in, single-out" operation mode, that is, they can only accommodate a single row of materials carried by multi-layer carrier boards, and manual placement of carrier boards one by one is required, resulting in low production efficiency and high labor costs. Utility Model Content
[0003] Based on this, and to address the aforementioned technical problems, a dual-inlet, dual-outlet material rack is provided.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A double-inlet, double-outlet material rack includes a rack body for horizontally placing multiple layers of material-bearing carrier plates at equal vertical distances. The rack body includes side plates arranged opposite each other, fixed to a frame. Multiple support assemblies for supporting the left and right edges of the carrier plates are provided on the opposite surfaces of the side plates. Each support assembly includes multiple support rollers arranged at intervals. The rack body consists of two rack bodies arranged side-by-side. The material rack also includes a lifting basket that moves up and down behind the two rack bodies under the drive of a first driving mechanism. The lifting basket includes a basket frame with two horizontal channels for horizontally conveying the carrier plates in the front-back direction, and two push arms that move up and down and horizontally forward and backward under the drive of a second driving mechanism to push the carrier plates on the two horizontal channels into the corresponding rack body. The two horizontal channels correspond one-to-one with the two rack bodies, and the width of each channel is equal to the distance between the side plates of the corresponding rack body. The second driving mechanism is fixed to the basket frame, and the push arms are connected to the corresponding second driving mechanism.
[0006] The beneficial effects of this utility model are as follows:
[0007] 1. Improve material handling efficiency
[0008] It adopts two left and right arranged material racks to form a "double in, double out" storage structure, doubling the material buffer capacity; with the two horizontal flow channels on the left and right of the lifting basket corresponding one-to-one with the material racks, two rows of carrier plates can be transported in parallel at the same time, effectively reducing the waiting time of loading and unloading trolleys, and can be adapted to double in, double out material trolleys and presses, improving the overall rhythm of the production line.
[0009] 2. Achieve automated loading and unloading and precise positioning
[0010] The lifting basket is raised and lowered via a first drive mechanism, accommodating carriers of different heights. The push arm, driven by a second drive mechanism, moves both vertically and horizontally, automatically pushing carriers from the horizontal flow channel into the corresponding rack body, replacing traditional manual placement and reducing labor costs. Simultaneously, the flow channel width matches the spacing between the rack side plates, ensuring no misalignment during carrier pushing. Attached Figure Description

[0023] The embodiments of this utility model will be described below with reference to the accompanying drawings. It should be noted that the embodiments described in this specification are not exhaustive and do not represent the only embodiments of this utility model. The following corresponding embodiments are only for clearly illustrating the utility model content of this patent and are not intended to limit its implementation. For those skilled in the art, different variations and modifications can be made based on the described embodiments. Any obvious variations or modifications that fall within the technical concept and utility model content of this utility model are also within the protection scope of this utility model.
[0024] like Figure 1 As shown, this utility model embodiment provides a double-inlet double-outlet material rack, including a frame 1100, two material rack bodies 1200, a first drive mechanism 1300, and a lifting basket 1400.
[0025] The two material racks are arranged at approximately 1200mm, and are used to horizontally place multiple layers of carrier plates containing materials at equal intervals.
[0026] like Figure 2 As shown, each rack body 1200 includes multiple pairs of side plates 1210 arranged opposite to each other. The side plates 1210 are fixed to the frame 1100 by bolts. The opposite surfaces of the side plates 1210 are provided with multi-layer support assemblies 1220 for supporting the left and right edges of the carrier plate. Each layer of support assembly 1220 includes multiple support rollers 1221 arranged at intervals and a slider 1222. The support rollers 1221 are rotatably fixed to the side plates 1210. The slider 1222 is fixed to the side plates 1210 by bolts and is located in front of the last support roller 1221. Its upper surface is flush with the apex of the support roller 1221 in the same layer. The slider 1222 is used to prevent the carrier plate from sliding out from the front when it is pushed into the rack body 1200.
[0027] The first drive mechanism 1300 is used to drive the lifting basket 1400 to rise and fall behind the two material rack bodies 1200, such as Figure 3 As shown, it includes an upper rotating shaft 1310 and a lower rotating shaft 1320 that are horizontal in the left-right direction, two transmission chain assemblies 1330 in the up-down direction, and a drive motor 1340.
[0028] The upper rotating shaft 1310 and the lower rotating shaft 1320 are arranged vertically at intervals, as shown in... Figure 3 and Figure 4 As shown, the upper rotating shaft 1310 is rotatably fixed to the top of the frame 1100 via three bearing seats 1311 (left, middle, and right). The three bearing seats 1311 are fixed to the frame 1100 by bolts. Similarly, the lower rotating shaft 1320 is also rotatably fixed to the bottom of the frame 1100 via three bearing seats (left, middle, and right) and is lower than the material rack body 1200.
[0029] The two upper sprockets 1331 of the two transmission chain assemblies 1330 are respectively fixed at both ends of the upper rotating shaft 1310, and the two lower sprockets 1332 of the two transmission chain assemblies 1330 are respectively fixed at both ends of the lower rotating shaft 1320. The drive motor 1340 is fixed on the top of the frame 1100 and is connected to the upper rotating shaft 1310 for transmission.
[0030] like Figure 5 and Figure 6 As shown, the lifting basket 1400 includes a basket frame 1410, two second drive mechanisms 1420 and two push arms 1430.
[0031] like Figure 5 As shown, the basketball hoop 1410 has two side panels 1411 arranged at intervals on the left and right, a partition frame 1412 located between the two side panels 1411, two support side panels 1413 arranged at intervals on the left and right, and a crossbeam 1414.
[0032] Two side baffles 1411 are located between two supporting side plates 1413, and multiple flow channel rollers 1411a arranged in a front-to-back configuration are rotatably disposed between the two side baffles 1411, such as... Figure 6 As shown, multiple flow channel rollers 1411a are synchronously driven by the same motor 1411b through gears and chains (a conventional method, which will not be described in detail here). The multiple flow channel rollers 1411a pass through the separator frame 1412 to form two horizontal flow channels on the left and right.
[0033] The two horizontal flow channels on the left and right correspond one-to-one with the two material rack bodies 1200, and the width of each flow channel is equal to the spacing of the corresponding material rack body side plate.
[0034] The inner surfaces of the two support side plates 1413 are respectively connected to the chains 1333 of the two transmission chain assemblies 1330. The inner surfaces of the support side plates 1413 also have guide strips 1413a for guiding the chains 1333. See [reference needed] Figure 7 .
[0035] like Figure 8 and Figure 9 As shown, the outer side of the support side plate 1413 is rotatably connected to two first guide wheels 1413b via left and right rotating shafts, which are used to guide the front and rear sides of the column 1110 on the rear side of the frame, forming a sliding fit between the lifting basket 1400 and the frame.
[0036] like Figure 7As shown, the inner side of the support side plate 1413 is rotatably connected to a second guide wheel 1413c via a pivot (not shown in the figure) in the front-back direction. This guide wheel 1413c is used for vertical guidance on the inner side of the column 1110. The second guide wheel 1413c contacts the column 1110 from the left and right via a window 1413d formed on the support side plate 1413. The second guide wheel 1413c is eccentrically fixed on the pivot, and the pivot can be locked by a nut. This structure allows the user to fine-tune and center the basket frame 1410 so that the two horizontal flow channels on the left and right are aligned with the two material rack bodies 1200 one after the other.
[0037] like Figure 8 and Figure 9 As shown, an electronic ruler 1111 is fixed on the outer side of the column 1110 to precisely control the height of the lifting basket so that the flow channel accurately connects to the support components 1220 of each layer of the material rack. The detection slider 1111a of the electronic ruler 1111 is fixed to the support side plate 1413 through the connecting frame 1111b and can be raised and lowered with the lifting basket 1400.
[0038] The upper and lower limit sensors are fixed at the top and bottom ends of the column 1110, respectively.
[0039] like Figure 5 and Figure 6 As shown, the crossbeam 1414 is located above the two horizontal flow channels and has four vertical plates 1414a, which are connected to the outer surfaces of the two side baffles 1411 by bolts.
[0040] Two second drive mechanisms 1420 are located above the two horizontal flow channels respectively, corresponding one-to-one with the two push arms 1430, and are used to drive the corresponding push arms 1430 to lift and move horizontally back and forth, so as to push the carrier plate on the corresponding horizontal flow channel into the corresponding material rack body.
[0041] like Figure 10 As shown, the second drive mechanism 1420 includes a front and rear linear module 1421 and a lifting module 1422. The front and rear linear module 1421 uses a rodless cylinder, which is fixed on the crossbeam 1414. The moving seat 1421a of the rodless cylinder has a horizontal mounting plate 1421b. Guide sleeves 1421c and guide rods 1421d are provided at the four corners of the mounting plate 1421b. The lifting module 1422 uses two lifting cylinders. The two lifting cylinders are symmetrically located on the left and right sides of the front and rear linear module 1421 and fixed on the mounting plate 1421b. The output shafts of the two lifting cylinders pass downward through the mounting plate 1421b.
[0042] like Figure 10 As shown, the push arm 1430 is plate-shaped, located below the mounting plate 1421b, and connected to the lower ends of the four guide rods 1421d and the lower ends of the output shafts of the two lifting cylinders.
[0043] The lower surface of the front side of the push arm 1430 has two gripping plates 1431 arranged at left and right intervals. The two gripping plates 1431 correspond to the two gripping holes 21 on the rear edge of the carrier plate 2. See [reference needed]. Figure 11 .
[0044] During operation, the rear ends of the two flow channels of the lifting basket 1400 first connect with the upstream feeding mechanism to pick up the two left and right carrier plates (each carrier plate contains material). Then, the lifting basket 1400 moves up and down so that the front ends of the two flow channels connect with the support components 1220 of the target layer of the two material rack bodies 1200. After connection, the two flow channels first transport the two carrier plates to the two material rack bodies 1200. When the two carrier plates disengage from the corresponding flow channels, the two push arms 1430 descend so that their front ends align with the rear edge of the corresponding carrier plate. Then, the two push arms 1430 advance, thereby pushing the corresponding carrier plate completely into the corresponding material rack body 1200. Repeating the above process can fill the two material rack bodies 1200.
[0045] like Figure 1 and Figure 2 As shown, in this embodiment, each rack body 1200 has 24 material positions. In practical applications, the upper 12 material positions are used for material trolleys to pick up materials, and the lower 12 material positions are used for buffering. Therefore, a blocking frame 1230 is set on the front side of the rack body 1200 corresponding to the area of the lower 12 material positions. The blocking frame 1230 is fixed to the frame 1100. When it is necessary to take out the carrier plate from the lower 12 material positions and send it to the upper 12 material positions, the two gripping plates 1431 on the push arm 1430 cooperate with the two gripping holes 21 on the rear edge of the carrier plate 2. First, the push arm 1430 pulls the carrier plate 2 out onto the flow channel, and then the lifting basket 1400 rises and sends it into the upper 12 material positions.
[0046] As can be seen from the above, the beneficial effects of the double-in, double-out loading and unloading trolley provided in this embodiment of the present invention are as follows:
[0047] 1. Improve material handling efficiency
[0048] It adopts two left and right arranged material racks to form a "double in, double out" storage structure, doubling the material buffer capacity; with the two horizontal flow channels on the left and right of the lifting basket corresponding one-to-one with the material racks, two rows of carrier plates can be transported in parallel at the same time, effectively reducing the waiting time of loading and unloading trolleys, and can be adapted to double in, double out material trolleys and presses, improving the overall rhythm of the production line.
[0049] 2. Achieve automated loading and unloading and precise positioning
[0050] The lifting basket is raised and lowered via a first drive mechanism, accommodating carriers of different heights. The push arm, driven by a second drive mechanism, moves both vertically and horizontally, automatically pushing carriers from the horizontal flow channel into the corresponding rack body, replacing traditional manual placement and reducing labor costs. Simultaneously, the flow channel width matches the spacing between the rack side plates, ensuring no misalignment during carrier pushing.
[0051] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
