Description

Technical Field

[0001] This invention relates to the field of electronic manufacturing auxiliary equipment technology, and more specifically to an intelligent storage device for storing and managing tubular solder paste. Background Technology

[0002] Solder paste is an essential soldering material in surface mount technology (SMT) production lines. Tube solder paste needs to be refrigerated before use to maintain its viscosity and performance, preventing flux evaporation and degradation. Before use, it needs to be removed from the refrigerated environment and allowed to warm up to avoid condensation due to temperature differences affecting soldering quality.

[0003] In existing technologies, solder paste is often packaged in cans similar in size to mineral water bottles, weighing up to 500 grams. At least two racks are needed to store sufficient quantities of this material under refrigeration, requiring a large storage volume. The solder paste in this application, however, is packaged in tubes, each weighing approximately 30-50 grams, making it much smaller and unsuitable for previous storage solutions. Furthermore, traditional transfer devices require extensive horizontal movement, occupying significant space and resulting in a less compact overall structure and low space utilization.

[0004] Therefore, there is an urgent need in this field for a storage device that is specifically designed for tubular solder paste, has a compact structure, and can achieve automated access and intelligent management, in order to solve the problems of large storage volume, low space utilization, and extensive management in the existing technology. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of the prior art and provide an intelligent storage cabinet that is specifically designed for tubular solder paste, has a compact structure, a high degree of automation, and precise management.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The transfer unit includes a transfer assembly, a feeding assembly, a discharging assembly, and a feeding assembly.

[0010] Tubular materials enter the cabinet through the feeding component and are then transferred to the refrigeration section for cold storage by the transfer component. When materials need to be removed, the transfer component transfers the materials to the discharging component in advance for reheating, and finally sends them to the discharging component for removal.

[0011] Furthermore, the transfer assembly and the electrical unit are located on the same side of the cabinet, the feeding assembly and the discharging assembly are located on the other side of the cabinet, and the discharging assembly is located on the other side of the cabinet opposite to the refrigeration unit.

[0018] The second magnet is fixed to the feed box;

[0019] The start button and the stop button are located on the cabinet near the refrigeration section of the feed inlet. The start button controls the first magnet to be energized and magnetically conducted to attract the second magnet, and the stop button controls the first magnet to be de-energized to separate the second magnet.

[0020] Furthermore, the discharge assembly is located on the side of the infeed assembly away from the refrigeration section, and includes a discharge port, a discharge frame, and a barcode scanner.

[0021] The discharge frame is located on the lower inner side of the discharge port and is used to place the material to be discharged.

[0023] A grating is installed at the discharge port.

[0024] Furthermore, the transfer unit also includes an NG component, which is located below the discharge component.

[0025] The NG component includes an NG inlet and an NG container.

[0026] The NG material box is located inside and below the NG material inlet, and its length exceeds the length of the feeding assembly.

[0027] The bottom of the NG material box is designed with a sloping structure that slopes towards the NG material inlet.

[0028] Furthermore, the transfer assembly includes a column, a fixing frame, a drive mechanism, and a fork assembly.

[0029] The uprights are fixed to the cabinet.

[0030] The fixing frame is slidably connected to the column and can move up and down;

[0031] The driving mechanism includes a rotary driving mechanism, a lateral driving mechanism, and a longitudinal driving mechanism:

[0032] The rotary drive mechanism is mounted on the fixed frame, and its bottom is connected to the top of the transverse drive mechanism.

[0033] The bottom of the lateral drive mechanism is connected to the top of the longitudinal drive mechanism;

[0034] The bottom of the longitudinal drive mechanism is connected to the fork arm assembly;

[0035] The longitudinal drive mechanism drives the fork assembly to move longitudinally, the lateral drive mechanism drives the longitudinal drive mechanism and the fork assembly to move laterally, and the rotary drive mechanism drives the lateral drive mechanism, the longitudinal drive mechanism and the fork assembly to rotate.

[0036] The fork assembly includes a fork and a fork drive mechanism. The fork consists of two opposing grippers, which are controlled to open and close by the fork drive mechanism.

[0037] Furthermore, the material feeding assembly includes a material feeding rack that is vertically fixed to the side wall of the cabinet.

[0038] Furthermore, the refrigeration section includes a refrigeration compartment, refrigerated shelves, and a sealed sliding door.

[0039] The cold storage compartment is provided with an opening for loading and unloading materials, and the sealed sliding door is movable and pressed against the opening.

[0040] The refrigerated rack is arranged in a turret-like shape in the center of the refrigeration compartment, and includes a rotating shaft, a support rod, and multiple circular support plates sleeved on the rotating shaft.

[0041] The material support plate includes a top plate and a bottom plate of the same diameter that are fixed to each other. Each top plate and bottom plate has one or more concentric through holes near their edges. The diameter of the through holes on the top plate is larger than the maximum diameter of the material, and the diameter of the through holes on the bottom plate is larger than the minimum diameter of the material but smaller than its maximum diameter. The smaller end of the material passes through the through hole on the top plate and is then engaged in the through hole on the bottom plate.

[0042] The support rod is disposed between the upper and lower adjacent support plates to support the support plates. The support rod is located inside the through hole of the support plate.

[0043] The rotating shaft can drive the material receiving plate to rotate the material to be retrieved to the opening of the cold storage compartment.

[0044] Furthermore, the sealed sliding door includes a door panel, a first bracket, a translation cylinder, a second bracket, and a pressing cylinder.

[0045] The four corners of the door panel are respectively fixedly connected to the clamping cylinder via the first bracket.

[0046] The clamping cylinders at the upper and lower ends of the door panel are fixedly connected to the translation cylinders via second brackets. The translation cylinders are located at the top of the refrigerator compartment and the bottom of the cabinet, respectively.

[0047] The translation cylinder drives the pressing cylinder and the door panel to move laterally, and the pressing cylinder drives the door panel to move longitudinally to press the opening of the refrigerator compartment.

A single rack can store a sufficient amount of material.

[0050] 2. It has achieved fully automated management of the entire process of tubular solder paste from warehousing, refrigeration, reheating to delivery, which has significantly improved production efficiency and reduced labor costs and operational error rates.

[0051] 3.

[0078] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0079] Example 1

[0080] See Figures 1 to 12 This embodiment provides a tubular solder paste intelligent storage cabinet, the main body of which is a vertical cabinet 1. The interior of the cabinet 1 is rationally divided into three main functional areas through space planning: a transfer section 2, a refrigeration section 3, and an electrical section 4. The refrigeration section 3 and the electrical section 4, which integrates control units, power modules, etc., are centrally located on the right side of the cabinet 1, while the transfer section 2, responsible for performing all material handling tasks, is located on the left side. This layout achieves physical separation between the power control area and the material flow area, resulting in clear wiring and logistics paths that do not interfere with each other. The overall structure is very compact, and space utilization is high.

[0081] The inbound process is as follows:

[0082] The operator first places single tubes of solder paste sequentially into the feed hopper 223 of the designated feeding assembly 22. After placing the material, the operator presses the start button 225 located next to the feed inlet 221. At this time, the electromagnetic suction mechanism 227 starts working. The first magnet (such as an electromagnet) fixed on the feeding frame 222 is energized to generate a strong magnetic force, which tightly attracts the second magnet (such as a magnetically conductive metal sheet) fixed on the feed hopper 223, thereby reliably locking the feed hopper 223 within the feeding frame 222. This design effectively prevents the feed hopper 223 from being accidentally pulled out during subsequent transfer, playing an important safety protection role. At the same time, the laser sensor 224 installed on the feeding frame 222 detects that the material has been placed in place and feeds this signal back to the control system. The system then records the material information (the material information can be automatically identified and recorded by the operator scanning the barcode before placing the material or by the RFID tag attached to the material).

[0083] Subsequently, the transfer assembly 21 receives the command and begins operation. The mounting frame 212 of the transfer assembly 21, driven by a drive motor (not shown), first moves along the vertically fixed column 211 to a height corresponding to the target feed box 223. Next, the rotary drive mechanism 213 mounted on the mounting frame 212 (e.g., a servo motor with a worm gear structure) begins operation, adjusting the orientation of the entire actuator below it (including the lateral drive mechanism 214, the longitudinal drive mechanism 215, and the fork assembly 216) in the horizontal plane, aligning it with the feed box 223. Then, the lateral drive mechanism 214 (e.g., a linear module) drives the longitudinal drive mechanism 215 and the fork assembly 216 below it to move along the X-axis (lateral), precisely positioning them above the material. Subsequently, the longitudinal drive mechanism 215 (e.g., a cylinder or electric actuator) drives the fork assembly 216 to extend along the Y-axis (longitudinal, i.e., towards the material). The two grippers at the front end of the fork assembly 216 close under the drive of the fork drive mechanism (such as a small cylinder or a motor-driven cam mechanism), firmly gripping the solder paste tube. Then, the longitudinal drive mechanism 215 retracts, removing the material from the feed box 223.

[0084] After material retrieval is completed, the transfer assembly 21 carries the material to the material retrieval opening of the refrigeration section 3. The translation cylinder 333 (installed on the top of the refrigeration chamber 31 and the bottom of the cabinet 1) of the control sealing sliding door 33 is activated, driving the door panel 331 connected to it via the second bracket 334, the clamping cylinder 335 and the first bracket 332 to move laterally, opening the opening of the refrigeration chamber 31. The transfer assembly 21 then coordinates and controls each drive mechanism to accurately transfer and store the clamped solder paste tube into a pre-designated storage location on the refrigerated material rack 32—that is, a specific through hole in a certain material support plate 323. During storage, the small end (nozzle end) of the solder paste tube passes through the corresponding through holes of the upper plate 323a and the lower plate 323b of the material support plate 323 in sequence, and is finally caught by the tube shoulder (that is, the part with the larger diameter of the tube body) at the edge of the through hole of the lower plate 323b, thereby achieving stable upright suspension of the material. After the material is stored, the translation cylinder 333 of the sealing sliding door 33 first drives the door panel 331 to reset and close the opening. Then, multiple pressing cylinders 335 set at the top and bottom act simultaneously, driving the door panel 331 to move longitudinally (perpendicular to the door panel plane) so that it is tightly pressed against the sealing strip around the opening of the cold storage compartment 31, forming a reliable seal and effectively preventing cold air leakage.

[0085] The outbound operation process is as follows:

[0086] Upon receiving a solder paste demand instruction from the production line (usually issued via the MES system), the control system prioritizes materials that have completed their reheating process. If none are available, it instructs the transfer assembly 21 to perform the outbound task. The transfer assembly 21 first moves to the opening of the refrigeration section 3 according to the instruction. The sealing sliding door 33 opens according to the above process. Simultaneously, the rotating shaft 321 of the refrigerated rack 32 rotates under the drive of a drive motor (not shown), rotating the receiving plate 323 containing the target solder paste tube to the pick-and-place station facing the opening. The fork assembly 216 of the transfer assembly 21 then extends into the refrigeration chamber 31, grips the designated solder paste tube, and removes it. After removal, the sealing sliding door 33 immediately closes and seals tightly to maintain the low-temperature environment inside the refrigeration chamber.

[0087] Next, the transfer component 21 transfers the extracted low-temperature solder paste tubes to the feeding rack of the feeding component 24. The feeding rack is a simple frame structure vertically fixed to the side wall of the cabinet. The material is placed on it for natural rewarming, allowing its temperature to slowly rise to room temperature, avoiding condensation due to temperature differences. The control system records the time when the material begins to rewarm. When the preset rewarming time (which can be set according to process requirements) is reached, the transfer component 21 operates again, removing the rewarmed solder paste tubes from the feeding rack and sending them to the discharging frame 232 of the discharging component 23. The barcode scanner 233 (such as a fixed barcode scanner or CCD reader) installed on the discharging frame 232 scans the barcode or QR code on the material again, performing a final check against the system's outbound instructions to ensure the absolute accuracy of the outbound material. The optical grating 234 installed at the discharging port 231 is used to detect whether the material has been taken away by the operator in a timely manner. Once the optical grating 234 detects that the material has been taken away, it sends a signal to the system, completing the outbound process.

[0088] To handle abnormal situations, this equipment is also equipped with an NG (Not Good) component 25. If abnormal situations occur, such as mismatched material information, failed barcode scanning, or material remaining at the discharge port for more than a set time, the system will determine the material as NG and control the transfer component 21 to place it into the NG container 252 of the NG component 25, located below the discharge component 23. The length of the NG container 252 is designed to exceed the length of the feeding component, facilitating the containment of abnormal materials in different states. Its bottom is designed with a sloping structure towards the NG discharge port 251, greatly facilitating operators to reach and handle these abnormal materials from the NG discharge port 251.

[0089] The key technical advantages of this embodiment are as follows:

[0090] 1. High space utilization: The transfer component 21 of this invention achieves Z-axis movement through a single column 211, combined with rotation, lateral (X-axis), and longitudinal (Y-axis) movement, realizing precise four-degree-of-freedom motion. Compared to Cartesian robots or gantry structures that require large-area horizontal movement, this structure is very compact, yet its range of motion can cover the entire storage and retrieval area, perfectly solving the problem of large space occupation by traditional horizontal movement mechanisms. Meanwhile, the turret-type refrigerated rack 32 used in the refrigeration section 3 achieves high-density material storage within the limited space of the refrigeration chamber 31 by rotating for storage and retrieval rather than linear movement, in conjunction with a circular support plate 323 capable of suspending multiple rows of materials. This is particularly suitable for the small-diameter, low-weight tubular solder paste described in this application, solving the problem of low space utilization and uneconomical use of traditional large-volume storage methods for such materials.

[0091] 2. Automated and intelligent management: Through the collaborative work of the transfer component 21 with the feeding, discharging, unloading, and NG components, and combined with sensors (laser sensors, gratings) and automatic identification equipment (barcode scanners), the entire process of material warehousing, storage, reheating and outbound is automated, as well as precise inventory management, expiration date monitoring and first-in-first-out (FIFO) control, which greatly improves the level of management refinement.

[0092] 3. Excellent sealing and preservation effect: The sealing sliding door 33 of the refrigeration section adopts a composite motion of translation and pressing. Through the positive pressure provided by the pressing cylinder 335, it ensures that the door panel 331 and the opening sealing strip are tightly fitted, which significantly reduces cold air leakage and ensures the refrigeration effect and equipment energy efficiency.

[0093] 4. The electrical unit 4 integrates core electrical components such as PLC (Programmable Logic Controller), temperature controller, frequency converter, power supply module, and communication module (such as Ethernet, RS485, etc.) to coordinate and control the operation of the entire storage cabinet (including the refrigeration system, various drive cylinders, motors, sensors, etc.) and to interact with the upper-level management system (such as MES) in real time to achieve comprehensive information management.

[0094] Example 2

[0095] This embodiment shares the same basic structure as Embodiment 1, with the main difference being the specific form of the drive mechanism. In Embodiment 1, the lateral and longitudinal drive mechanisms preferably employ precision linear modules driven by servo motors to achieve high-precision positioning and high movement speed. However, in this embodiment, considering cost and control complexity, the lateral drive mechanism 214 and the longitudinal drive mechanism 215 can be replaced with cylinder drives. Specifically, the lateral drive mechanism 214 can use a rodless cylinder or a standard cylinder in conjunction with a slide rail to achieve lateral movement; the longitudinal drive mechanism 215 can directly use a standard cylinder to achieve the longitudinal extension and retraction of the fork arm assembly 216. Although the accuracy is slightly lower than that of servo motor drives, for applications where accuracy requirements are not extremely stringent, cylinder drives can fully meet the requirements and have the advantages of low cost and easy maintenance. The rotary drive mechanism 213 can also be achieved by using a more cost-effective rotary cylinder to achieve rotation at a specific angle (e.g., 0-180 degrees).

[0096] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
