Description

Technical Field

[0001] This invention relates to the field of PCB printing technology, and more particularly to a consumable material supply device. Background Technology

[0002] In PCB printing, the timely supply and replacement of consumables such as squeegees, screen printing stencils, and solder paste are crucial to production continuity and printing quality. Currently, the industry primarily relies on manual labor for this consumable supply operation.

[0003] Operators need to manually retrieve consumables from the warehouse according to equipment requirements, and after manual verification, transport them to the printing equipment for replacement.

[0004] This model has the following problems:

[0005] ① High dependence on manpower: Frequent replacement of consumables requires dedicated personnel to handle and coordinate, which not only increases labor costs, but also easily leads to prolonged equipment standby time due to untimely personnel allocation.

[0006] ② Prominent efficiency bottleneck: The speed of manual handling is limited by the physical strength of workers and the physical distance between the warehouse and the production line, making it difficult to match the material change cycle requirements of high-speed printing equipment, thus restricting the improvement of overall production efficiency.

[0007] As PCB manufacturing evolves towards higher precision and more complex production lines, traditional manual material feeding methods are no longer sufficient to meet production demands. Therefore, there is a need to develop a consumable material feeding system to automate the supply of consumable materials for PCB printing, thereby reducing labor costs and improving production efficiency.

[0008] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0078] See Figure 1 This invention provides a consumables and auxiliary material feeding device, comprising:

[0079] AGV trolley 1;

[0080] The feeding module is installed on the top of the AGV trolley 1 and includes a drawer-type storage assembly 2 for storing jigs and / or scrapers, a solder paste storage rack 3 for storing solder paste boxes 100, a stencil storage assembly 4 for storing screen printing stencils 200, and a transfer robot 5 for transferring the jigs and / or scrapers, solder paste boxes 100 and screen printing stencils 200.

[0081] The consumable and auxiliary material feeding equipment provided in this embodiment operates as follows:

[0082] After receiving the dispatch instruction, AGV 1 autonomously navigates to the designated area of ​​the warehouse;

[0083] The transfer robot 5 operates precisely according to the preset program, placing the jigs and / or scrapers in the warehouse into the drawer-type storage component 2, and placing the solder paste box 100 into the solder paste storage rack 3, and placing the screen printing stencil 200 into the stencil storage component 4.

[0084] The AGV then runs along the predetermined path to the PCB printing equipment;

[0085] According to production needs, at appropriate material change times, the transfer robot 5 removes at least one of the fixture and / or scraper of the drawer-type storage component 2, the solder paste box 100 on the solder paste storage rack 3, and the screen printing stencil 200 of the stencil storage component 4 and transfers it to the PCB printing equipment.

[0086] When the transfer robot 5 transfers various consumable materials to the PCB equipment, the PCB printing equipment also delivers dirty jigs and / or scrapers, empty solder paste boxes 100, and dirty screen printing stencils 200. Therefore, after the PCB printing equipment receives new consumable materials, the transfer robot 5 puts the dirty consumable materials delivered by the PCB printing equipment back to the corresponding idle position in the feeding module, thereby completing the recycling operation of dirty consumable materials.

[0087] Therefore, the consumable material supply equipment provided by the present invention can realize the automated supply of consumable materials for PCB printing, thereby reducing labor costs and improving production efficiency.

[0088] Optionally, the consumable material feeding device further includes a CCD component for acquiring image information and communicating with the transfer robot 5. Specifically, the CCD component is installed on the transfer robot 5 to acquire visual information of various materials and equipment, thereby achieving high-precision visual positioning and completing accurate material handling operations.

[0089] See Figure 2 In this embodiment, the drawer-type storage component 2 includes:

[0090] Drawer frame 201;

[0091] A plurality of horizontal sliding shelves 202 are arranged at intervals from top to bottom along the drawer frame 201, and the horizontal sliding shelves 202 are slidably connected to the drawer frame 201 in the horizontal direction.

[0092] The shelf push-pull mechanism 203 is located on the side of the drawer frame 201 and is used to pull each of the transverse shelf 202 out to the outside of the drawer frame 201 and to push the transverse shelf 202 back into the drawer frame 201.

[0093] Furthermore, the shelf push-pull mechanism 203 includes:

[0094] U-shaped base 2031;

[0095] A base linear drive mechanism 2032, the drive end of which is connected to the U-shaped base 2031, is used to drive the U-shaped base 2031 to move up and down.

[0096] A shelf push-pull block 2033 is used to push and pull each of the transverse shelf 202;

[0097] A linear drive mechanism 2034 is mounted on the U-shaped base 2031, and the drive end of the linear drive mechanism 2034 is connected to the shelf push-pull block 2033, which is used to drive the shelf push-pull block 2033 to move closer to or away from each of the transverse shelves 202 along the push-pull direction of each transverse shelf 202.

[0098] Optionally, the shelf push-pull block 2033 is provided with an upward-opening U-shaped handle groove 2033a, and the transverse shelf 202 is provided with a handle part 2021 for engaging with the U-shaped handle groove 2033a.

[0099] Furthermore, the U-shaped base 2031 is also provided with a plurality of support rollers 2035, each of which is used to support the portion of the transverse shelf 202 that has been pulled out.

[0100] In this embodiment, the working process of the shelf push-pull mechanism 203 is as follows:

[0101] (1) When it is necessary to pull out the horizontal sliding shelf 202 of a certain layer:

[0102] The base linear drive mechanism 2032 first drives the U-shaped base 2031 to rise and fall vertically, so that the U-shaped handle groove 2033a of the shelf push-pull block 2033 is slightly lower than the handle part 2021 of the target horizontal shelf 202;

[0103] The linear drive mechanism 2034 then actuates, causing the shelf push-pull block 2033 to move horizontally toward the target transverse shelf 202 until the U-shaped handle groove 2033a is located directly below the handle part 2021.

[0104] Then the base linear drive mechanism 2032 drives the U-shaped base 2031 to rise vertically, so that the handle part 2021 enters the U-shaped handle groove 2033a;

[0105] After the U-shaped handle groove 2033a and the handle part 2021 are engaged, the linear drive mechanism 2034 of the pull block runs in the opposite direction, smoothly pulling the horizontal shelf 202 out of the drawer frame 201.

[0106] (2) During the process of pulling out the horizontal moving shelf 202:

[0107] The 2035 sets of support rollers support the extended part of the transverse shelf 202 in real time, and the bending moment generated by the weight of the shelf is offset by rolling friction.

[0108] The shelf push-pull block 2033 continuously maintains traction on the buckle 2021, ensuring that the shelf slides smoothly along the straight track.

[0109] Once the transverse shelf 202 is fully pulled out, the transfer robot 5 can remove the fixtures and / or scrapers inside the transverse shelf 202; or, put the dirty fixtures and / or scrapers into the transverse shelf 202.

[0110] (3) When it is necessary to push back the horizontal sliding shelf 202:

[0111] The linear drive mechanism 2034 drives the push-pull block 2033 of the shelf in the forward direction, and pushes the handle 2021 through the U-shaped handle groove 2033a.

[0112] The horizontal sliding shelf 202 is precisely reset along the slide rail under the action of pushing force.

[0113] See Figures 3-5 In this embodiment, the steel mesh storage component 4 includes a U-shaped frame 401, a plurality of lifting shelves 402 that slide up and down along the U-shaped frame 401, and a shift-type direct drive mechanism 403 for driving any of the lifting shelves 402 to move up and down independently.

[0114] Optionally, the solder paste storage rack 3 is fixed to the side of the U-shaped frame 401 and has several solder paste trays for the solder paste box 100 to be placed in.

[0115] Furthermore, the U-shaped frame 401 is provided with a plurality of horizontally arranged and parallel vertical guide grooves 4011;

[0116] Each vertical guide groove 4011 is provided with a corresponding lifting shelf 402, and the end of the lifting shelf 402 is provided with a lifting part extending outward through the corresponding vertical guide groove 4011.

[0117] Optionally, the shift-type direct drive mechanism 403 includes:

[0118] Shift lock mount 4031;

[0119] The shift slider 4032 is slidably connected to the shift fixing seat 4031 along the arrangement direction of each of the vertical guide grooves 4011; wherein, the shift slider 4032 is provided with a plurality of clearance grooves for the lifting part to pass downward and a plurality of lifting blind grooves to restrict the lifting part from passing downward.

[0120] A slider linear drive mechanism 4033 is mounted on the shift fixing seat 4031, and the drive end of the slider linear drive mechanism 4033 is connected to the shift slider 4032. It is used to drive the shift slider 4032 to slide relative to the shift fixing seat 4031 so that the lifting blind groove is vertically aligned with the lifting parts of the different lifting shelves 402.

[0121] A fixed seat linear drive mechanism 4034 is provided, the drive end of which is connected to the shift fixed seat 4031 and is used to drive the shift fixed seat 4031 to move up and down, thereby driving the lifting plate 402 located above the lifting blind groove to move up and down.

[0122] In this embodiment, there are three lifting shelves 402, and the lifting parts of each lifting shelf 402 are sequentially referred to as the first lifting part 4021a, the second lifting part 4021b, and the third lifting part 4021c.

[0123] The number of the clearance slots is two, and the two clearance slots are respectively referred to as the first clearance slot 4032b and the second clearance slot 4032d;

[0124] The number of lifting blind slots is three, and the three lifting blind slots are respectively referred to as the first lifting blind slot 4032a, the second lifting blind slot 4032c, and the third lifting blind slot 4032e;

[0125] Among them, the first lifting blind slot 4032a, the first clearance through slot 4032b, the second lifting blind slot 4032c, the second clearance through slot 4032d, and the third lifting blind slot 4032e are arranged in sequence.

[0126] See Figure 6 When the first lifting part 4021a is vertically aligned with the first lifting blind groove 4032a, the second lifting part 4021b is vertically aligned with the second clearance groove 4032d, and the third lifting part 4021c is located outside the shift slider 4032, only the first lifting part 4021a moves up and down with the shift slider 4032;

[0127] See Figure 7 When the second lifting part 4021b is vertically aligned with the second lifting blind groove 4032c, both the first lifting part 4021a and the third lifting part 4021c are located outside the shift slider 4032, and only the second lifting part 4021b moves up and down with the shift slider 4032.

[0128] See Figure 8 When the third lifting part 4021c is vertically aligned with the third lifting blind groove 4032e, the first lifting part 4021a is located outside the shift slider 4032, and the second lifting part 4021b is vertically aligned with the first clearance groove 4032b, only the third lifting part 4021c moves up and down with the shift slider 4032;

[0129] This arrangement of through slots and blind slots allows the shift slider 4032 to complete the independent lifting operation of the three lifting sections within a very short stroke, thereby improving the structural compactness of the equipment and meeting the design requirements for miniaturization.

[0130] Initially, the shift slider 4032 is positioned lower than each of the lifting sections, and the working process of the steel mesh storage assembly 4 is as follows:

[0131] (1) See Figure 6 When it is necessary to raise the lifting shelf 402 corresponding to the first lifting section 4021a to take out or put in the screen-printed steel mesh 200:

[0132] ① The shift slider 4032 moves to the first lifting blind groove 4032a and aligns with the first lifting part 4021a. At this time: the second lifting part 4021b enters the second clearance groove 4032d and the third lifting part 4021c is located outside the shift slider 4032;

[0133] ② The linear drive mechanism 4034 of the fixed seat is activated, driving the shift slider 4032 to rise. At this time: the first lifting blind groove 4032a precisely drives the first lifting part 4021a to move upward, while the second and third lifting shelves 402 are not driven and remain stationary;

[0134] ③ The transfer robot 5 then grabs the screen-printed steel mesh 200 or places the recycled screen-printed steel mesh 200.

[0135] (2) See Figure 7 When it is necessary to raise the lifting shelf 402 corresponding to the second lifting section 4021b to take out or put in the screen-printed stencil 200:

[0136] ① The shift slider 4032 slides laterally to align the second lifting blind groove 4032c with the second lifting part 4021b. At this time: the first lifting part 4021a is aligned with the third lifting blind groove 4032e (but is not constrained), and the third lifting part 4021c is located outside the shift slider 4032;

[0137] ② The linear drive mechanism 4034 drives the shift fixed seat 4031 to rise and fall. At this time: the second lifting blind groove 4032c drives the second lifting part 4021b to move up and down, the lifting shelf 402 corresponding to the second lifting part 4021b rises and falls independently, and the other shelves remain stationary;

[0138] ③The transfer robot arm 5 then grabs the screen printing steel mesh 200 or places the recycled screen printing steel mesh 200;

[0139] (3) See Figure 8 When it is necessary to raise the lifting shelf 402 corresponding to the third lifting section 4021c to take out or put in the screen-printed stencil 200:

[0140] ① The linear drive mechanism 4033 drives the shift slider 4032 to slide laterally, so that the third lifting blind groove 4032e is vertically aligned with the third lifting part 4021c. At this time: the first lifting part 4021a is located outside the shift slider 4032 (outside the range of action of the mechanism), and the second lifting part 4021b moves freely through the first clearance groove 4032b;

[0141] ② The linear drive mechanism 4034 drives the shifting fixed seat 4031 to rise. At this time, the third lifting blind groove 4032e lifts the third lifting part 4021c upward. The lifting plate 402 corresponding to the third lifting part 4021c rises, thereby driving the screen printing steel mesh 200 it carries to reach the storage and retrieval height, or to facilitate receiving and transferring the dirty screen printing steel mesh 200 put in by the robot arm 5.

[0142] ③ The transfer robot 5 then grabs the screen-printed steel mesh 200 or places the recycled screen-printed steel mesh 200.

[0143] In summary, the consumable and auxiliary material feeding equipment provided in this embodiment has the following advantages:

[0144] ① AGV trolley 1 + transfer robot arm 5: Through autonomous navigation and collaborative operation with the robot arm, the entire process of supplying consumables from the warehouse to the printing equipment is automated, reducing manual intervention.

[0145] ②Drawer-type storage component 2 (horizontal sliding shelf 202 + shelf push-pull mechanism 203): adopts a layered slide rail and roller support design to improve the storage density of jigs / scrapers, while reducing the frictional resistance of pushing and pulling.

[0146] ③ Steel mesh storage component 4 (shifting direct drive mechanism 403): Through the precise cooperation between the shifting slider 4032 and the lifting blind slot, the independent lifting and storage of multi-layer screen-printed steel mesh 200 is realized, saving space and operating efficiently.
