Description

Technical Field

[0001] This utility model belongs to the technical field of chip mounter feeding, specifically a chip mounter feeding device. Background Technology

[0002] In the manufacturing process of electronic components, surface mount technology (SMT) is a crucial step. The SMT feeding device, as an important piece of equipment in this process, directly affects the efficiency and quality of the SMT assembly.

[0003] Early surface mount device (SMT) feeding devices had relatively simple structures and limited functionality. For example, some traditional feeding devices typically had fixed feed racks, which could not be flexibly adjusted to accommodate SMT materials of different sizes, resulting in a narrow range of applications. When dealing with SMT materials of various sizes, frequent changes to the feeding device were required, significantly impacting production efficiency. Moreover, these devices often used a single clamping method, making it difficult to stably hold SMT materials of different shapes and sizes. During the feeding process, problems such as SMT displacement and falling off were prone to occur, seriously affecting the accuracy and quality of the SMT placement.

[0004] With the continuous development of electronic technology, the requirements for surface mount technology (SMT) processes are becoming increasingly stringent, and the market has placed higher expectations on the performance of SMT feeding devices. To meet production demands, some improved feeding devices have emerged, and some have begun to adopt adjustable structures. However, most of these devices have complex adjustment methods, are inconvenient to operate, and have limited adjustment accuracy.

[0005] The search revealed a feeder for a pick-and-place machine (publication number: CN222509851U) that uses a structure of screws, sliding bars, and sliding rods in conjunction with baffles. While this structure can adjust the internal space of the storage cylinder and the sliding direction of the material to some extent, it is only suitable for specific types of materials and has extremely poor adaptability to different sizes of pick-and-place components. Its operation relies on manual adjustment of screws and other components, which is inefficient and makes it difficult to guarantee the accuracy of each adjustment. This technical solution exposes significant limitations when facing the diverse needs of pick-and-place production, and it is difficult to meet the current fast and precise pace of pick-and-place production.

[0006] In the current field of surface mount technology (SMT) manufacturing, there is an urgent need for a feeding device with a reasonable structural design, convenient and quick adjustment, stable and reliable clamping, and the ability to adapt to various sizes of SMT materials, in order to improve the overall efficiency and quality of the SMT process and reduce production costs. This SMT feeding device was developed and designed based on this background, aiming to solve the aforementioned problems in existing technologies and provide a more efficient and reliable feeding solution for SMT production. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a patch feeding device that solves the technical problems of complex adjustment methods, inconvenient operation and limited adjustment accuracy of most current equipment.

[0008] The solution adopted in this utility model is: a patch feeding device, characterized in that it includes:

[0009] The two feeding racks are both designed with C-shaped openings, and the two feeding racks are close to each other on one side of the opening. Each feeding rack is equipped with a clamping plate that can slide along the inner wall of the feeding rack.

[0010] Two adjusting frames are respectively located at the top and bottom of the feeding frame, and the two feeding frames are movably positioned between the two adjusting frames;

[0011] An adjustment assembly, mounted on an adjustment frame, is used to drive two adjustment frames to move relative to each other simultaneously, thereby changing the distance between the two feeding frames;

[0012] The clamping assembly, located on the feeding rack, is used to drive the clamping plate to slide linearly within the feeding rack.

[0013] Preferably, the adjusting assembly includes: a threaded rod and a power device. The threaded rod is rotatably connected to one of the adjusting frames and is driven to rotate by the power device. Two feeding frames are threadedly connected to the threaded rod and are symmetrically arranged about the center of the adjusting frame. The threaded rod is a bidirectional screw. The power device includes a motor fixedly connected to the adjusting frame, and the bidirectional screw is driven by the motor. The threaded rod includes two screws with opposite thread directions. The power assembly includes a bidirectional motor fixedly connected to the adjusting frame, and the two screws are respectively connected to the bidirectional motor.

[0014] The threaded rod in the adjustment assembly works ingeniously with the power unit. When driven by a bidirectional screw and a motor fixed on the adjustment frame, the forward and reverse rotation of the motor directly drives the bidirectional screw to rotate, enabling the two feed racks, which are threadedly connected and centrally symmetrically arranged, to move synchronously and stably relative to each other, achieving rapid and precise spacing adjustment. When the threaded rod consists of two lead screws with opposite thread directions connected to a bidirectional motor, the bidirectional motor can independently control the rotation of the two lead screws, further improving the flexibility and precision of the adjustment and meeting the special requirements for feed rack spacing adjustment in different production scenarios.

[0015] Preferably, the adjustment assembly further includes a guide member, which includes: multiple guide grooves on the two adjustment frames and multiple guide blocks on the two conveyor frames, wherein the multiple guide blocks are slidably engaged with the guide grooves, and the sliding direction of the guide blocks is consistent with the width direction of the conveyor frames.

[0016] Stable guiding structure: The adjusting assembly is equipped with guide components, namely multiple guide grooves on the adjusting frame and multiple guide blocks on the feeding frame, which slide in conjunction with the direction of movement of the guide blocks being consistent with the width direction of the feeding frame. This structure ensures the stability of the feeding frame during the adjustment process, avoiding deviation or shaking, and guaranteeing the accuracy and reliability of the adjustment. In actual production, it can effectively prevent placement position deviations caused by unstable feeding frame adjustment, thereby improving placement quality.

[0017] Preferably, the clamping assembly includes a telescopic rod, which is fixedly connected to the conveyor frame. The output end of the telescopic rod is fixedly connected to the clamping plate, and the clamping plate is moved by the telescopic movement of the telescopic rod.

[0018] Reliable clamping drive: The telescopic rod in the clamping assembly is fixedly connected to the feed rack, and its output end is connected to the clamping plate. The telescopic rod's extension and retraction can stably drive the clamping plate to slide linearly within the feed rack, thereby achieving reliable clamping of the patch material. Compared to traditional simple clamping methods, this design provides a more stable and controllable clamping force, effectively preventing the patch from shifting or falling off during feeding, and improving the accuracy and quality of patch placement.

[0019] Preferably, a plurality of auxiliary rollers are rotatably connected to the clamping plate, and the axial direction of the auxiliary rollers is perpendicular to the length direction of the feeding frame.

[0020] Auxiliary rollers reduce damage: Several auxiliary rollers are rotatably connected to the clamping plate, with their axes perpendicular to the length of the feed frame. When clamping the patch material, the auxiliary rollers reduce the friction between the clamping plate and the patch, preventing scratches or damage to the patch. Simultaneously, during the feeding process, the auxiliary rollers provide support and guidance, allowing the patch to be transported more smoothly, further improving the stability and reliability of the feeding process.

[0021] Preferably, a conveyor belt is provided inside the conveyor frame along its length.

[0022] Highly efficient material handling: The conveyor belt installed along the length of the feed rack can quickly and stably transport the patch materials. Compared with traditional manual feeding or inefficient conveying methods, the conveyor belt greatly improves the feeding speed, reduces manual operation, lowers labor intensity, and at the same time ensures the continuity and stability of feeding, thereby improving overall production efficiency.

[0023] Beneficial effects:

[0024] By using adjustment components mounted on the adjustment frame, two adjustment frames can be driven to move relative to each other simultaneously, thereby precisely changing the spacing between the two feed frames. Adaptable to various surface mount specifications, the adjustable spacing of the feed frames and the flexible clamping method of the clamping plate allow this feeding device to accommodate surface mount materials of different sizes and shapes. Whether it's small chip mounts or larger power module mounts, stable feeding can be achieved by adjusting the feed frame spacing and clamping plate position, greatly expanding the applicability of the feeding device and meeting diverse production needs. Compared to traditional fixed-spacing feed frames, frequent equipment changes are unnecessary, significantly improving production efficiency. Attached Figure Description

[0037] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1-5 The detailed description of the embodiments will clearly demonstrate this. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0038] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0039] Example 1: A patch feeding device, characterized in that it comprises:

[0040] Feeder rack 1: Select aluminum alloy sheet of appropriate thickness, process it into C-shaped section through precision stamping and bending process. The length of feeder rack 1 is flexibly determined according to actual production needs. On the inner wall of feeder rack 1, aluminum alloy slide rail with specific surface treatment is installed to provide a smooth track for the sliding of clamping plate 11.

[0041] Clamping plate 11: Made of stainless steel plate of a certain thickness, its surface is treated to reduce friction with the material being applied. A ball-bearing slider is installed at the contact point between the clamping plate 11 and the feed rack 1 slide rail to ensure the clamping plate 11 can slide flexibly. Multiple auxiliary rollers 42 are rotatably connected to the clamping plate 11 via stainless steel shafts. The auxiliary rollers 42 are made of a specific material, and their length is slightly less than the internal width of the feed rack 1 to ensure uniform force application when clamping the material.

[0042] Adjustment frame 2: Welded from carbon steel square tubing of appropriate thickness, customized according to the dimensions of feeding frame 1 to ensure that feeding frame 1 can move smoothly within it. Mounting holes are reserved at the top and bottom of adjustment frame 2 for fixing adjustment assembly 3 and guide member 5 (Example 2).

[0043] Adjustment component 3: The threaded rod 31 is a double-acting screw made of high-strength alloy steel. The double-acting screw is rotatably connected to one of the adjustment frames 2 via two deep groove ball bearings. The bearing seats are made of cast iron and are fixed to the adjustment frame 2 with bolts. The motor 32 is a DC motor with appropriate power and equipped with a speed controller. It is connected to the double-acting screw via a coupling to ensure that the motor 32 can stably drive the double-acting screw to rotate. The two feeding frames 1 are connected by nuts that mate with the threads of the double-acting screw. The nuts are made of a material with good wear resistance and transmission efficiency. In addition, the threaded rod 31 includes two lead screws with opposite thread directions. The power component includes a double-acting motor 33 fixedly connected to the adjustment frame 2. The two lead screws are respectively connected to the double-acting motor 33. Driving the double-acting motor 33 drives the lead screws to move, realizing the movement of the two sets of feeding frames 1.

[0044] Clamping assembly 4: The telescopic rod 41 is an electric telescopic rod 41 with a certain stroke and sufficient thrust. The fixed end of the telescopic rod 41 is fixed by a mounting seat welded to the feeding frame 1. The mounting seat is made of carbon steel of appropriate thickness. The output end of the telescopic rod 41 is connected to the clamping plate 11 by a threaded connection to ensure a stable connection.

[0045] Conveyor Belt 6: Conveyor Belt 6 is made of rubber of appropriate thickness with anti-slip texture on the surface, and its width is slightly smaller than the internal width of the feeding rack 1. Conveyor Belt 6 is driven by two aluminum alloy rollers, one of which is connected to an AC motor with appropriate power. The motor drives the roller to rotate via belt drive. Plastic protective baffles of a certain height are installed on both sides of Conveyor Belt 6 to prevent the patch material from falling off during the conveying process.

[0046] Operating steps

[0047] Equipment Installation: Install the two adjusting frames 2 on the top and bottom of the feeding frame 1 respectively, ensuring that the feeding frame 1 can move freely between the adjusting frames 2. Install the adjusting assembly 3, and install the double-acting screw on the adjusting frame 2 through the bearing. Connect the motor 32 and the coupling (e.g., Figure 4 (As shown). Connect the feeder 1 to the double-ended screw via a nut. Install the clamping assembly 4, attach the fixed end of the telescopic rod 41 to the feeder 1, and connect the output end to the clamping plate 11. Install the auxiliary roller 42 onto the clamping plate 11, and finally install the conveyor belt 6 and its drive unit.

[0048] Equipment debugging: Connect the power supply, start the motor 32, test whether the rotation direction and speed of the bidirectional screw are normal, and observe whether the feeding rack 1 can move smoothly relative to the motor. Debug the telescopic rod 41 and check whether its telescopic action is smooth and whether it can accurately drive the clamping plate 11. Start the conveyor belt 6 and check whether its operation is smooth and whether the speed meets the production requirements.

[0049] Material feeding: Based on the width of the material to be bonded, start motor 32 and adjust the spacing between the feeding racks 1. Place the material on conveyor belt 6, activate telescopic rod 41, and gently clamp the material with auxiliary roller 42 on clamping plate 11. Start conveyor belt 6 to transport the material to the bonding station.

[0050] Example 2: A patch feeding device, based on Example 1, further includes a guide member 55 in the adjustment assembly 33. The guide member 55 (Example 2): The guide groove 51 is made of stainless steel and is fixed to the adjustment frame 2 by bolts. The length of the guide groove 51 is the same as the length of the adjustment frame 2, and the width is customized according to the size of the guide block 52 to ensure smooth sliding of the guide block 52. The guide block 52 is made of a material with low friction coefficient and high wear resistance, and is installed on the feeding frame 1, precisely matching the guide groove 51.

[0051] In use, based on Example 1, install guide component 5. Fix guide groove 51 to adjustment frame 2, and install guide block 52 on feeding frame 1, ensuring that guide block 52 can slide smoothly within guide groove 51. Repeat the debugging steps of Example 1, while checking the operation of guide component 5. During the relative movement of feeding frame 1, observe whether the cooperation between guide block 52 and guide groove 51 is smooth and whether it can effectively prevent feeding frame 1 from deviating, which is the same as the material feeding steps of Example 1. During the feeding process, due to the function of guide component 5, the movement of feeding frame 1 is more stable, which can effectively ensure the conveying accuracy of patch material.

[0052] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
