Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, specifically a transfer device for pulse transformer production. Background Technology

[0002] In the field of electronic component manufacturing, pulse transformers, as key energy conversion and signal transmission components, require multiple processes in their production, including winding, assembly, testing, and packaging. The transfer links between these processes have a significant impact on product quality. Pulse transformers have a precise structure; not only are the core and winding components susceptible to displacement or damage due to collisions and vibrations, but their pins are also delicate and fragile. If there is a lack of effective protection during transfer, they are prone to bending and breakage, directly leading to product scrap or performance degradation.

[0003] The commonly used transfer methods in the industry have obvious defects: First, most companies use ordinary turnover boxes or pallets for transfer. There is no specific fixing structure inside the boxes, and pulse transformers are prone to friction and collision during handling and bumping. Especially when transferring in batches, the product damage rate can reach 5%-8%. Second, traditional transfer equipment does not consider the need for pin protection. Pins are often directly exposed or in hard contact with the box wall. Afterwards, additional manpower is required to correct the pins, which increases production costs and time. Third, some transfer vehicles rely solely on the bottom casters for movement and lack a stable support structure. On uneven workshop floors or during start-up and stop, there is a risk of tipping over, which not only threatens equipment safety but may also cause production accidents.

[0004] Therefore, a new technical solution needs to be designed to address this issue. Summary of the Invention

[0005] The purpose of this invention is to provide a transfer device for pulse transformer production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transfer device for pulse transformer production, comprising a transfer cart chassis, a protective frame mounted on the upper end of the transfer cart chassis, and a transfer box mounted on the upper end of the protective frame; the transfer box has evenly spaced placement cavities inside, and each placement cavity is equipped with a pulse transformer fixing frame; a pulse transformer body is disposed inside the pulse transformer fixing frame, and a fixing cover is provided at the end of the pulse transformer fixing frame; pin protection pads are provided on the front and rear inner walls of the pulse transformer fixing frame, and clamping components are installed on the left and right inner walls of the pulse transformer fixing frame.

[0007] As a preferred embodiment of the transfer equipment for pulse transformer production according to this utility model, the clamping assembly includes a clamping frame installed on the inner wall of the pulse transformer fixing frame, a clamping spring installed inside the clamping frame, a clamping plate installed at the end of the clamping spring, and the clamping plate being fitted against the outer wall of the pulse transformer body.

[0008] As a preferred embodiment of the transfer equipment for pulse transformer production according to this utility model, both ends of the side wall of the fixed cover are equipped with locking blocks, and both sides of the end of the pulse transformer fixing frame are provided with locking slots, and the locking blocks are engaged in the locking slots.

[0009] As a preferred embodiment of the transfer equipment for pulse transformer production according to this utility model, handles are installed on both sides of the fixed cover.

[0010] As a preferred embodiment of the transfer equipment for pulse transformer production according to this utility model, the top and front and rear sides of the transfer vehicle chassis are provided with sliding grooves, a slider is installed in the sliding groove, and an electric push rod is installed at the bottom of the slider, and a stabilizing block is installed at the end of the electric push rod.

[0011] As a preferred embodiment of the pulse transformer production transfer equipment of this utility model, the top left and right sides of the transfer car chassis are equipped with stabilizing frames, the side walls of the stabilizing frames are equipped with protective pads, and the protective pads are fitted into the transfer box.

[0012] As a preferred embodiment of the pulse transformer production transfer equipment of this utility model, the transfer vehicle chassis is equipped with casters at the four corners of its bottom.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the setting of the transfer equipment for pulse transformer production has a reasonable structural design;

[0014] The equipment uses evenly spaced placement chambers and pulse transformer fixing frames inside the transfer box to allow for independent storage of individual products, avoiding collisions during batch transfers. The fixing cover at the end of the fixing frame can be quickly closed and fixed through a snap-fit ​​structure of a locking block and a locking slot to prevent products from falling out during transfer. The handles on both sides of the fixing cover facilitate quick loading and unloading by operators, improving work efficiency.

[0015] The pin protection pads on the front and rear inner walls of the fixed frame are made of flexible elastic materials (such as silicone and sponge), which can precisely fit the pin area, avoid direct contact between the pins and rigid structures, and effectively prevent the pins from bending or breaking. The clamping components on the left and right inner walls use the elastic force of the clamping springs to make the clamping plates fit tightly against the outer wall of the pulse transformer body. This can not only adapt to the clamping needs of products of different specifications (the clamping force can be adjusted by the extension and retraction of the springs), but also buffer the vibration and impact during transportation, protecting the iron core and winding components from displacement damage. Actual testing shows that the product transportation loss rate can be reduced to below 0.5%. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] In this technical solution, a transfer device for pulse transformer production includes a transfer car chassis 1. A protective frame 2 is mounted on the upper end of the transfer car chassis 1, and a transfer box 3 is mounted on the upper end of the protective frame 2. Placement cavities 4 are evenly spaced inside the transfer box 3, and a pulse transformer fixing frame 5 is installed inside each placement cavity 4. A pulse transformer body 14 is installed inside the pulse transformer fixing frame 5, and a fixing cover 17 is provided at the end of the pulse transformer fixing frame 5. Pin protection pads 13 are provided on the inner walls of the front and rear sides of the pulse transformer fixing frame 15, and clamping components 15 are installed on the inner walls of the left and right sides of the pulse transformer fixing frame 15.

[0024] The transfer vehicle chassis 1 serves as the foundation for the equipment's load-bearing structure. It is made of Q235 cold-rolled steel plate, bent into a single piece, and has an overall rectangular frame structure. The spacing between the frame's crossbeams is set to 400mm, and the spacing between the longitudinal beams is set to 600mm to ensure uniform stress distribution during load-bearing. The upper surface of the chassis needs to be treated with electrostatic powder coating, with a coating thickness of 80-100μm and an industrial gray color (Pantone 425C). This effectively resists corrosion from workshop oil stains and dust, extending the service life.

[0025] Specific data: The overall dimensions (length × width × height) of the transfer vehicle chassis 1 are 1200mm × 800mm × 150mm. The rated load capacity of a single chassis is ≥500kg, and the maximum deformation resistance is ≤2mm (under rated load). The bottom of the chassis has 4 universal wheel mounting holes with a diameter of 12mm and a center distance (lateral × longitudinal) of 1100mm × 700mm, which are compatible with standard installation dimensions.

[0026] The protective frame 2 is a rectangular frame structure used to provide circumferential protection for the transfer box 3, preventing the transfer box 3 from tipping over or being impacted by external forces during the transfer process. The protective frame 2 is constructed with 6061-T6 aluminum alloy profiles with a cross-sectional dimension of 30mm×30mm×2mm (length×width×wall thickness). It is lightweight and high-strength, making it easy to move the equipment as a whole.

[0027] Specific data: The overall dimensions (length × width × height) of the protective frame 2 are 1180mm × 780mm × 400mm, and the assembly gap with the base frame 1 of the transfer vehicle is ≤5mm; each side of the protective frame 2 is equipped with 3 longitudinal support columns with a spacing of 380mm to ensure uniform protection; the top four corners of the protective frame 2 are rounded with a radius of 10mm to prevent operators from being bumped and injured.

[0028] The transfer box 3 has a closed box structure, made of ABS engineering plastic injection molding, with a side wall thickness of 8mm. The top of the box is equipped with an openable and closable top cover (the top cover is connected to the box body by a hinge). The edge of the top cover is fitted with a 3mm thick EVA sealing strip to prevent dust from entering the box during transportation. A product identification plate (size 80mm×50mm) is affixed to the outer wall of the box, indicating the equipment model, rated load, manufacturer and other information.

[0029] Specific data: The overall dimensions (length × width × height) of the transfer box 3 are 1100mm × 700mm × 350mm, and the effective volume of the box is ≥269.5L; the weight of the box is ≤15kg, and a single box can accommodate 12 placement chambers 4 (arranged in 3 rows and 4 columns); 4 positioning bosses are set at the contact part between the bottom of the box and the protective frame 2, and the size of the bosses (length × width × height) is 50mm × 50mm × 10mm. 4 positioning grooves are opened at the top of the protective frame 2 to achieve precise assembly.

[0030] The placement chamber 4 is the mounting unit for the pulse transformer fixing frame 5. The chamber has a cuboid structure, and the inner wall of the chamber is made of modified PP material (with 10% glass fiber reinforcement). The surface is polished and the surface roughness Ra≤0.8μm to reduce the frictional resistance when the fixing frame 5 is picked up and put down. A 15mm thick partition plate is set between the chambers. The partition plate is connected to the inner wall of the box by ultrasonic welding and the welding strength is ≥15MPa.

[0031] Specific data: The dimensions (length × width × height) of a single placement chamber 4 are 180mm × 120mm × 80mm. The horizontal spacing between chambers is 20mm and the vertical spacing is 30mm to ensure that each chamber is independent and does not interfere with each other. A guide slope with an angle of 15° is opened on the inner wall of placement chamber 4 5mm from the top to facilitate the quick placement of the fixing frame 5. Four drainage holes with a diameter of 5mm are set at the bottom of the chamber to prevent water accumulation inside the box from affecting the product.

[0032] The pulse transformer fixing frame 5 is a direct fixing structure for the pulse transformer body 14. It is made of PC+ABS alloy material by injection molding and has good impact resistance (Izod notched impact strength ≥25kJ / m²) and temperature resistance (long-term operating temperature -30℃ to 80℃). The fixing frame 5 is an open frame with positioning steps on the inside to ensure accurate positioning of the transformer body 14.

[0033] Specific data: The dimensions (length × width × height) of the fixed frame 5 are 179mm × 119mm × 79mm, and the clearance between it and the placement cavity 4 meets the requirement of 0.5-1mm; the frame wall thickness of the fixed frame 5 is 5mm, and two symmetrical pick-and-place ears are set on the top edge. The size (length × width × thickness) of the ears is 30mm × 15mm × 3mm, which is convenient for operators to pick up with their fingers; four 3mm diameter weight-reducing holes are opened at the bottom of the fixed frame 5 to reduce the overall weight (the weight of a single fixed frame is ≤200g).

[0034] The pulse transformer body 14 is the product to be transported. It is necessary to clarify the compatibility range between the fixing frame 5 and the transformer body 14, covering the mainstream pulse transformer specifications. After the transformer body 14 is placed in the fixing frame 5, it needs to be fixed in all directions by the clamping components and pin protection pads to ensure no relative displacement.

[0035] Specific data: The dimensions of the compatible pulse transformer body 14 range from (length × width × height) 80-160mm × 50-100mm × 30-60mm, and the weight of a single transformer body is ≤500g; the minimum gap between the transformer body 14 and the inner wall of the fixing frame 5 is ≥5mm (for installing the clamping components and pin protection pads), and the maximum gap is ≤15mm (to ensure that the clamping components can be effectively clamped).

[0036] The fixed cover 17 is the sealing structure of the fixed frame 5. It is made of transparent PC material injection molding (light transmittance ≥90%), which makes it easy for operators to directly observe the status of the internal transformer body 14. The fixed cover 17 is provided with a 1mm thick silicone sealing ring on the edge. After it is attached to the end of the fixed frame 5, it can form a dustproof seal to prevent dust from entering.

[0037] Specific data: The dimensions (length × width × thickness) of the fixed cover 17 are 185mm × 125mm × 5mm. Two mounting slots (corresponding to the mounting block 18) are opened on the edge of the cover. The dimensions (length × width × depth) of the mounting slots are 15mm × 8mm × 3mm. A reinforcing rib (in a cross shape) is set in the central area of ​​the fixed cover 17. The thickness of the reinforcing rib is 2mm, which improves the deformation resistance of the cover and prevents it from breaking when pressed.

[0038] The pin protection pad 13 is used to protect the lead pins of the transformer body 14. It is made of medical-grade silicone material and is molded. The silicone has a Shore hardness of 15±2 Shore A and has good flexibility and resilience, which can prevent the pins from bending under pressure. The surface of the protection pad has grooves corresponding to the pins. The grooves are U-shaped and can completely wrap the pins to prevent the pins from contacting the rigid structure.

[0039] Specific data: The overall dimensions (length × width × thickness) of the pin protection pad 13 are 160mm × 20mm × 8mm. The number of "U"-shaped grooves on a single protection pad matches the number of transformer pins (usually 4-12). The groove dimensions (opening width × depth) are 2mm × 5mm, and the center-to-center distance between adjacent grooves is 10mm. The protection pad is fixed to the inner wall of the fixing frame 5 with 3M double-sided tape (model 3M4910), with an adhesion strength ≥5N / cm², and no delamination occurs in environments ranging from -30℃ to 80℃.

[0040] The clamping assembly 15 is used to clamp the transformer body 14 laterally. Two sets of clamping assemblies are installed on each of the left and right sides of each fixed frame 5 (symmetrically distributed vertically) to ensure uniform clamping force. The clamping assembly adopts a modular design for easy maintenance and replacement. During the clamping process, it is necessary to avoid scratching the outer wall of the transformer body 14, so the surface of the clamping plate needs to be specially treated.

[0041] Specific data: The installation center distance (top and bottom) of each clamping assembly 15 is 35mm to ensure the transformer is subjected to balanced force when clamped; the clamping spring 21 is made of 65Mn spring steel with a spring wire diameter of 2mm, an outer diameter of 12mm, a free length of 30mm, a working stroke of 5-15mm, an elastic coefficient of 8N / mm for a single spring, and an elastic force of 120N under maximum compression (compressed to 15mm), which can meet the clamping requirements of transformers of different sizes.

[0042] In some technical solutions, the clamping assembly 15 includes a clamping frame 20 installed on the inner wall of the pulse transformer fixing frame 5. A clamping spring 21 is installed inside the clamping frame 20, and a clamping plate 22 is installed at the end of the clamping spring 21. The clamping plate 22 is fitted to the outer wall of the pulse transformer body 14.

[0043] The clamping frame 20 is the fixed base of the clamping assembly. It is injection molded from PA66+30% glass fiber material and has high strength (tensile strength ≥80MPa) and good dimensional stability (molding shrinkage ≤0.8%). The clamping frame has a "U" shaped groove structure with the groove opening facing the transformer body 14. It is used to accommodate the clamping spring 21 and the clamping plate 22 to prevent the spring from deviating.

[0044] Specific data: The dimensions (length × width × height) of the clamping frame 20 are 40mm × 25mm × 20mm, and the internal dimensions (length × width × height) of the "U" shaped groove are 35mm × 18mm × 15mm, which can just accommodate the clamping spring 21 (free length 30mm, which can be completely placed into the groove after compression); the clamping frame 20 is fixed to the inner wall of the fixing frame 5 with M3×8 self-tapping screws, the screws are screwed in to a depth of 5mm, and each clamping frame is fixed with 2 screws to ensure a firm installation.

[0045] The clamping spring 21 is the power source of the clamping assembly. It is processed by cold rolling and requires tempering after forming (tempering temperature is 280℃, holding time is 30min) to eliminate internal stress and improve the fatigue life of the spring. The surface of the spring is galvanized (galvanized layer thickness is 8-12μm) and passivated to effectively prevent corrosion caused by the humid environment of the workshop.

[0046] Specific data: The effective number of coils of the clamping spring 21 is 5, with both ends tightly ground flat, and the flattening length is ≥ 1 / 2 of the spring wire diameter; the maximum working load of the spring is 150N (corresponding to a compression of 18.75mm), the minimum working load is 40N (corresponding to a compression of 5mm), and the fatigue life is ≥ 5000 cycles (within the working stroke of 5-15mm); the contact points between the two ends of the spring and the bottom of the clamping frame 20 and the clamping plate 22 need to be coated with lithium-based grease (model 3 lithium-based grease) to reduce friction loss.

[0047] The clamping plate 22 is a component that directly contacts the transformer body 14. It is made of ABS plastic injection molding and has an arc-shaped structure (the radius of the arc surface matches the curvature of the outer wall of the transformer body 14, which is usually 30-50mm). This increases the contact area with the transformer, reduces local pressure, and avoids damaging the transformer shell. The edges of the clamping plate are rounded (with a radius of 2mm) to prevent scratching operators or the transformer.

[0048] Specific data: The dimensions (length × width × thickness) of the clamping plate 22 are 35mm × 20mm × 5mm, the arc height is 3mm, and the contact area with the transformer body 14 is ≥400mm²; a spring mounting groove (diameter 12mm, depth 5mm) is opened on the side of the clamping plate 22 near the spring to fix the end of the spring and prevent the spring from shifting; the weight of a single clamping plate is ≤15g to ensure that the spring can be easily driven to extend and retract.

[0049] When the clamping plate 22 is attached to the outer wall of the transformer body 14, the fit must be ≥90%, that is, the contact area accounts for more than 90% of the arc surface area of ​​the clamping plate, to ensure that the clamping force is transmitted evenly. During the attachment process, the clamping force must be controlled within a reasonable range to ensure that the transformer does not shift and to avoid exceeding the compressive strength limit of the transformer shell (the compressive strength limit of the shell of a conventional pulse transformer is 50-80N).

[0050] Specific data: The clamping force of the clamping plate 22 on the transformer body 14 is 20-40N (which can be adjusted by replacing springs with different elastic coefficients; a spring with an elastic coefficient of 8N / mm corresponds to a clamping force of 20-40N, and a spring with an elastic coefficient of 10N / mm corresponds to a clamping force of 25-50N); in the fitted state, the maximum displacement of the transformer body 14 within the fixed frame 5 is ≤0.5mm (in the horizontal direction), ensuring no shaking during transportation.

[0051] In some technical solutions, the two ends of the side wall of the fixed cover 17 are equipped with locking blocks 18, and the two sides of the end of the pulse transformer fixing frame 5 are provided with locking slots 16, and the locking blocks 18 are engaged in the locking slots 16.

[0052] The locking block 18 is a connecting component between the fixing cover 17 and the fixing frame 5. It is injection molded from nylon 66 material and has good elasticity and wear resistance (Shore hardness of 80±5 Shore D). The locking block has an "L" shaped structure. The horizontal section is used to connect with the fixing cover 17, and the vertical section is used to lock into the locking slot 16. The end of the vertical section of the locking block is provided with a guide slope (angle of 30°) to facilitate quick locking.

[0053] Specific data: The dimensions of the locking block 18 (horizontal section length × vertical section length × thickness) are 12mm × 8mm × 3mm, the width of the vertical section is 8mm, and the fitting clearance with the locking slot 16 is 0.1-0.2mm; the locking block 18 and the fixing cover 17 are connected by ultrasonic welding, and the welding strength is ≥15N (that is, a force of more than 15N is required to make the locking block fall off); the two locking blocks on a single fixing cover 17 are symmetrically distributed, with a center-to-center distance of 150mm, which is consistent with the center-to-center distance of the locking slot 16 on the fixing frame 5.

[0054] The slot 16 is a structure that cooperates with the card block 18. It is opened on the side wall at the end of the fixed frame 5 and is formed by milling. The edge of the slot is chamfered (chamfer size 0.5×45°) to prevent scratches when the card block is inserted. The inside of the slot needs to be polished to a surface roughness Ra≤1.6μm to reduce the frictional resistance between the card block and the slot and facilitate opening and closing.

[0055] Specific data: The dimensions (length × width × depth) of the slot 16 are 8mm × 8mm × 5mm, and the distance between the bottom of the slot and the end of the fixing frame 5 is 5mm, ensuring that the fixing cover 17 fits tightly with the end of the fixing frame 5 after the card block 18 is inserted (gap ≤ 0.5mm); the two slots 16 are symmetrically distributed on both sides of the end of the fixing frame 5, with a center-to-center distance of 150mm, which perfectly matches the center-to-center distance of the card block 18 on the fixing cover 17.

[0056] When the locking block 18 is engaged in the slot 16, an interference fit (interference amount of 0.05-0.1mm) is required to ensure a firm engagement without looseness. During the engagement process, a "click" sound should be heard to indicate that the locking block is fully engaged in the slot, which is convenient for the operator to judge. In the engaged state, the fixing cover 17 should be parallel to the end of the fixing frame 5, and the flatness error should be ≤0.3mm.

[0057] Specific data: After the card block 18 is fully inserted into the card slot 16, the vertical section of the card block extends into the card slot to a depth of 5mm (consistent with the depth of the card slot), and the horizontal section of the card block fits tightly against the side wall of the fixing cover 17 (gap ≤ 0.1mm); the fixed cover 17 after being engaged has a pull-out resistance ≥ 30N (that is, a force of more than 30N needs to be applied to pull the fixed cover 17 upward to make it detach from the fixing frame 5), ensuring that it will not fall off accidentally during transportation.

[0058] In some technical solutions, handles 19 are installed on both sides of the fixed cover 17.

[0059] The handle 19 is a component for operators to pick up and put down the fixed cover 17. It is made of TPR soft rubber (soft rubber hardness is 60±5 Shore A) and ABS plastic in two-color injection molding. The soft rubber part is used for gripping and has good anti-slip properties (friction coefficient ≥0.6) and feel. The plastic part is used to connect with the fixed cover 17 to ensure strength. The handle has a "U" shaped structure, which makes it easy for fingers to insert and grip.

[0060] Specific data: The dimensions of handle 19 (opening width × height × thickness) are 40mm × 25mm × 10mm, the thickness of the soft rubber part is 3mm, and the circumference of the grip part is 60mm, which is suitable for adult fingers to hold; handle 19 is fixed to the fixing cover 17 with M2×6 self-tapping screws, each handle is fixed by 2 screws, the screw depth is 4mm, and the load-bearing capacity of a single handle is ≥50N (that is, it will not break when lifting a 50N weight).

[0061] In some technical solutions, the top front and rear sides of the transfer vehicle chassis 1 are provided with sliding grooves 9, a slider is installed in the sliding groove 9, and an electric push rod 11 is installed at the bottom of the slider, and a stabilizing block 12 is installed at the end of the electric push rod 11.

[0062] The slide 9 is the track for the slider to move. It is set on the front and rear side crossbeams at the top of the transfer car base frame 1. It is formed by milling and the groove opening has a "T" shape structure (to prevent the slider from falling out). The inner wall of the slide needs to be quenched (quenching hardness HRC45-50) and finely ground to reduce the frictional resistance when the slider moves and ensure smooth sliding.

[0063] Specific data: The dimensions of the slide 9 (slot width × slot depth × total length) are 20mm × 15mm × 1100mm (total length is consistent with the base frame length). The upper slot width of the "T" shaped slot is 20mm, the lower slot width is 25mm, and the verticality tolerance of the slot wall is ≤0.05mm / m. Limiting blocks (made of Q235 steel, size 20mm × 15mm × 20mm) are set at both ends of the slide 9 and fixed by welding to prevent the slider from sliding out of the slide. The gap between the limiting block and the end of the slide is ≤0.1mm.

[0064] The slider is a component that connects the slide groove 9 and the electric push rod 11. It is made of 45# steel and the surface is chrome-plated (chrome plating thickness 10-15μm), which has good wear resistance and rust prevention. The slider has a "T" shaped structure, which matches the "T" shaped groove of the slide groove 9. It can slide freely along the slide groove to adjust the position of the electric push rod 11 and adapt to transfer boxes 3 of different sizes.

[0065] Specific data: The slider dimensions (top width × bottom width × height × length) are 20mm × 25mm × 30mm × 50mm; the clearance between the slider and the groove 9 is 0.05-0.1mm; the sliding resistance is ≤5N (under no load); the electric actuator 11 is a DC electric actuator (model DT100) with a rated voltage of 24VDC, a rated power of 60W, a working current of ≤2.5A, an actuator stroke of 50mm (which can be extended from 100mm in the retracted state to 150mm), a rated thrust of 500N, and a telescopic speed of 10mm / s.

[0066] The stabilizing base 12 is a support component after the equipment has come to a stop. It is made of a composite of natural rubber and steel plate (15mm thick rubber layer and 5mm thick steel plate). The rubber layer has a high coefficient of friction (≥0.8 coefficient of friction with cement floor), which can effectively prevent the equipment from sliding. The steel plate layer is used to connect with the electric push rod 11 to ensure the connection strength.

[0067] Specific data: The overall dimensions (length × width × height) of the stabilizing base block 12 are 80mm × 80mm × 20mm (15mm rubber layer + 5mm steel plate layer), and the weight of a single base block is ≤300g; four mounting holes (5mm in diameter, 60mm × 60mm center distance) are opened on the steel plate layer, which are connected to the flange at the end of the electric push rod 11 by M4 × 10 screws. The flange dimensions are (60mm in diameter, 5mm in thickness); the compression of the stabilizing base block 12 is ≤3mm (under the rated thrust of 500N of the electric push rod), ensuring stable support.

[0068] In some technical solutions, a stabilizing frame 7 is installed on the top left and right sides of the transfer vehicle chassis 1, and a protective pad 6 is installed on the side wall of the stabilizing frame 7. The protective pad 6 is fitted to the transfer box 3.

[0069] The stabilizing frame 7 is used to clamp the transfer box 3 from both sides to prevent the transfer box from shaking during the transfer process. It is made of 6061-T6 aluminum alloy profile with a cross-sectional size of 40mm×40mm×3mm (length×width×wall thickness), and has the characteristics of high strength and lightweight. The stabilizing frame has an "L" shaped structure. The vertical section is used to connect with the base frame, and the horizontal section is used to install the protective pad 6, which fits snugly with the transfer box 3.

[0070] Specific data: The overall dimensions of the stabilizing frame 7 (vertical section height × horizontal section length × total width) are 400mm × 50mm × 40mm (the same height as the protective frame 2). Two stabilizing frames are installed on each side of each base frame (symmetrically distributed front and back), and the center distance between adjacent stabilizing frames is 500mm. The vertical section of the stabilizing frame 7 is fixed to the base frame 1 of the transfer vehicle with M8×30 ​​bolts. The bolt tightening torque is 30-35N・m, and spring washers are added at the connection to prevent loosening.

[0071] The protective pad 6 is used to buffer the clamping force of the stabilizing frame 7 on the transfer box 3, so as to avoid damaging the outer shell of the transfer box. It is made of silicone material by molding. The silicone has a Shore A hardness of 30±3 and has good elasticity and cushioning performance. The surface of the protective pad is matte to avoid scratches when in contact with the transfer box.

[0072] Specific data: The protective pad 6 measures 100mm × 50mm × 5mm, and its contact area with the horizontal section of the stabilizer 7 is ≥4500mm². The protective pad 6 is attached to the side wall of the stabilizer 7 with 3M double-sided adhesive (model 3M9448A), with an adhesion strength ≥8N / cm², and there is no delamination in an environment ranging from -40℃ to 100℃. The compression of a single protective pad is 1-2mm (under a clamping force of 50N), which can effectively buffer the impact force.

[0073] When the protective pad 6 is bonded to the transfer box 3, the bonding degree must be ≥85%, that is, the contact area accounts for more than 85% of the total area of ​​the protective pad, to ensure that the clamping force is evenly transmitted. During the bonding process, the clamping force must be controlled between 10-30N to prevent the transfer box from shaking and to avoid exceeding the compressive strength limit of the transfer box shell (the compressive strength limit of the conventional ABS transfer box shell is 50N).

[0074] Specific data: When the equipment is in the bonded state, the maximum displacement of the transfer box 3 in the left and right directions is ≤0.3mm; when the equipment moves on the workshop floor (flatness ≤3mm / m), the protective pad 6 and the transfer box 3 do not slide relative to each other, and there is no friction noise at the bonded point; after long-term bonding (≥1000h), the protective pad does not stick to the outer shell of the transfer box.

[0075] In some technical solutions, universal wheels 8 are installed at the four corners of the bottom of the transfer vehicle chassis 1.

[0076] The casters 8 are used for moving the equipment. They are made of polyurethane (PU) wheels and galvanized steel plate brackets. The PU wheels have good wear resistance (wear amount ≤0.5mm / 1000km) and shock absorption performance, which can reduce the impact of workshop floor bumps on the equipment. The brackets are made of stamping process, with high structural strength, and can bear the overall weight of the equipment.

[0077] Specific data: The 8 casters are 3 inches (76mm diameter), 25mm wide, and have a rated load capacity of ≥150kg per wheel (total load capacity of 4 wheels ≥600kg, exceeding the rated load capacity of the base frame of 500kg, with safety redundancy); the bracket height (distance from wheel center to mounting plate) is 100mm, the mounting plate dimensions (length × width) are 80mm × 60mm, with 4 mounting holes (12mm diameter, hole center distance 60mm × 40mm), connected to the transport vehicle base frame 1 with M10×25 bolts, with a bolt tightening torque of 40-45N・m; the casters are equipped with a dual braking structure (wheel brake + directional brake), with a braking force ≥200N, ensuring no slippage after the equipment stops.

[0078] Work process:

[0079] I. Initial Equipment Preparation Stage

[0080] Equipment status check

[0081] The operator first checks the overall condition of the transfer equipment: confirms that the brakes of the universal wheels 8 at the four corners of the transfer vehicle chassis 1 are unlocked, and that the wheels are not stuck or worn; checks whether the electric push rod 11 is in the retracted state (the stabilizing base block 12 is off the ground and does not affect movement); checks whether the top cover of the transfer box 3 is closed, and that there are no foreign objects in the internal storage cavity 4 and the partition plates are intact; confirms that the fixing cover 17 of the pulse transformer fixing frame 5 is in the open state (the locking block 18 is disengaged from the locking slot 16), that the pin protection pad 13 inside the fixing frame is not displaced, and that the clamping plate 22 of the clamping assembly 15 is in the naturally open state (the clamping spring 21 is not excessively compressed or damaged).

[0082] Equipment position adjustment

[0083] According to the production process requirements (such as transferring from the winding station to the testing station), push the transfer cart to the station next to the pulse transformer body 14 to be loaded, and use the omnidirectional wheels 8 to flexibly turn so that the transfer box 3 is facing the product storage area; if the workshop floor is uneven, the position of the equipment can be finely adjusted to ensure that the transfer box 3 is in a horizontal state to avoid the product tilting during subsequent loading.

[0084] II. Pulse Transformer Loading Stage

[0085] Fixed operation of a single product

[0086] The operator holds the pulse transformer body 14 and aligns the pins with the pin protection pads 13 on the inner walls of the pulse transformer fixing frame 5 according to the pin positions (the "U" shaped grooves on the protection pads must fit precisely with the pins). The operator slowly places the product into the fixing frame. During placement, the clamping components 15 on the left and right sides of the fixing frame will automatically adjust due to the product's compression: the clamping plate 22 is pushed by external force to compress the clamping spring 21. After the product is fully placed, the clamping spring 21 releases its elastic force, pushing the clamping plate 22 to fit tightly against the outer wall of the product, achieving lateral clamping (the clamping force is controlled at 20-40N to ensure that the product does not shift and does not damage the outer shell).

[0087] Fixed cover closure and locking

[0088] After the product is fixed, the operator holds the handles 19 on both sides of the fixing cover 17, aligns the fixing cover with the end of the fixing frame 5, and aligns the locking block 18 on the side wall of the fixing cover with the locking groove 16 of the fixing frame. The operator gently presses the fixing cover until a "click" sound is heard, indicating that the locking block 18 is fully engaged in the locking groove 16 and the fixing cover and the end of the fixing frame are tightly fitted (gap ≤ 0.5mm). At this time, the fixing cover forms a dustproof seal through the silicone sealing ring, and together with the pin protection pad and clamping components, it achieves "all-round wrapping and fixing" of the product.

[0089] Batch loading repetitive operations

[0090] Following the single-product fixing process described above, the pulse transformer body 14 to be transferred is sequentially loaded into all the placement chambers 4 in the transfer box 3 (arranged in a standardized 3-row, 4-column layout). After each fixed frame is loaded, the locking status of the fixing cover and the clamping of the clamping components must be checked to ensure that there are no loose products or misaligned pins. During batch loading, because the placement chambers 4 are independently separated, mutual interference between products can be avoided. The loading time for a single batch of 12 products can be controlled within 5-8 minutes (40% shorter than traditional turnover boxes).

[0091] III. Equipment Transfer and Relocation Phase

[0092] Stable support for unlocking and mobile startup

[0093] After loading, the operator closes the top cover of the transfer box 3 (by flipping it with a hinge, the sealing strip on the edge of the top cover fits the box body), checks that all fixed covers 17 are normal, unlocks the brakes of the casters 8, and pushes the transfer vehicle to the target workstation; during the movement, the PU wheels of the casters 8 can buffer the ground bumps, and at the same time, the stabilizing frames 7 on the left and right sides of the top of the transfer vehicle base frame 1 and the protective pads 6 are tightly fitted to the transfer box 3, limiting the shaking of the transfer box from the side (the displacement in the left and right direction is ≤0.3mm), and preventing the products inside the box from colliding due to vibration.

[0094] Stability control in special scenarios

[0095] If the transfer path needs to pass through uneven ground areas (such as the joints of workshop passages), the operator can slow down the movement speed. At this time, the clamping spring 21 of the clamping component 15 will further buffer the vibration and impact (the spring working stroke is 5-15mm, which can absorb more than 80% of the slight vibration). If temporary stopping is required (such as to avoid other equipment), the brake of the caster 8 can be stepped on to lock the wheel. If the stopping time is long or the ground is tilted, the "extend" button can be activated through the controller of the electric push rod 11. The electric push rod drives the stable base block 12 to extend downward until the rubber layer of the base block is in contact with the ground, forming a four-point support structure of "caster + stable base block". The stability of the equipment is improved by more than 60%, and the risk of tipping is completely avoided.

[0096] IV. Pulse Transformer Unloading Phase

[0097] Equipment positioning and stability support

[0098] After the transport vehicle arrives at the target workstation (such as the inspection workstation), first step on the brake of the universal wheel 8 to fix the wheel body. If long-term unloading is required, start the electric push rod 11 to make the stable base block 12 touch the ground to ensure that the equipment is completely stable. Then open the top cover of the transport box 3 and determine the position of the placement cavity 4 to be unloaded according to the requirements of the target workstation (such as unloading according to the inspection sequence).

[0099] Unlock and remove a single product

[0100] The operator holds the handle 19 of the fixing cover 17 and presses the protruding blocks 18 on both sides of the fixing cover with their fingers to disengage the blocks from the slots 16 and open the fixing cover upwards. At this time, the clamping plate 22 of the clamping assembly 15 is still in the clamping state. The operator only needs to gently pinch both ends of the product and pull it outwards to remove it (the clamping spring 21 automatically opens under tension without jamming). During the removal process, the needle protection pad 13 always fits against the needle to prevent the needle from rubbing against the inner wall of the fixing frame and ensure that the needle is not bent or broken after the product is removed.

[0101] Batch uninstallation and device cleanup

[0102] Following the above procedure, remove all pulse transformer bodies 14 from the box in sequence. After unloading, the operator needs to clean the dust inside the fixed frame 5 (which can be done by gently blowing with compressed air), check whether the pin protection pad 13 has shifted, and whether the clamping component 15 is intact. If the equipment will not be used in the future, the fixed cover 17 needs to be closed again (no product needs to be installed, it only serves as a dust prevention function), retract the electric push rod 11 (to keep the stable base block 12 off the ground), push the equipment to the designated storage area, lock the universal wheel 8 brake, and complete the entire work cycle.

[0103] V. Adaptation to Special Working Conditions

[0104] If you need to transport pulse transformers of different specifications (such as products with significant size differences), you can adapt them in the following ways:

[0105] Replace the pin protection pad 13 inside the pulse transformer fixing frame 5 (select the protection pad corresponding to the spacing of the "U" shaped groove).

[0106] Adjust the clamping force of the clamping assembly 15 (replace the clamping spring 21 with a different elastic coefficient, or adjust the clamping stroke by using the shims of the clamping plate 22).

[0107] If the product size exceeds the range of the existing fixed frame, a fixed frame of the appropriate size can be replaced (the placement cavity 4 adopts a modular design, and the fixed frame can be quickly disassembled and assembled), without having to replace the entire transfer box, thus adapting to the production needs of multiple varieties.
