Detailed Implementation

[0015] 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.

[0016] like Figure 1-4 As shown, this utility model provides an electronic component EPO foam transfer tray with positioning slots 201, including a tray body 101 integrally foamed from EPO foam material and an adjustment cavity 1501. The top surface of the tray body 101 has a plurality of positioning slots 201 evenly distributed. The positioning slots 201 have a dovetail groove structure, and the width of the groove gradually narrows from the opening end to the bottom to form an elastic locking space. The bottom of the positioning slots 201 is provided with an arc-shaped support part 401 that matches the shape of the electronic component pins. The arc-shaped support part 401 is integrally formed with the positioning slots 201.

[0017] The tray body 101 is integrally foamed from EPO foam material. The positioning slot 201 on the top surface is designed as a dovetail groove structure, with the groove width gradually narrowing from the opening end to the bottom. Utilizing the elastic properties of EPO foam, an elastic locking space is formed. When electronic components are placed inside, the groove wall generates an inward squeezing force, achieving initial fixation of the components. The arc-shaped support part 401 at the bottom matches the shape of the electronic component pins, and the complementary shape provides precise support and positioning for the pins, preventing pin deformation under stress.

[0018] The anti-slip ridges 1101 on both sides of the positioning slot 201 extend along the depth direction, which increases the friction between the slot wall and the surface of the electronic component to prevent the component from sliding during transportation; the guide groove between adjacent ridges can guide liquid (such as condensate) or dust on the surface of the tray to drain along the slot, avoiding accumulation in the slot.

[0019] The detachable reinforcing frame 301 at the edge is snapped to the pallet body 101 via a snap-fit ​​structure 1001. The honeycomb reinforcing ribs inside the frame utilize the mechanical properties of the honeycomb structure to disperse external forces and enhance the overall impact and deformation resistance of the pallet. The positioning bosses 701 at the four corners of the bottom surface of the frame are connected to the metal substrate 1201 on the bottom surface of the pallet body 101 via a magnetic adsorption layer, further improving the connection stability between the frame and the pallet.

[0020] The adjustable elastic pressure plate 1401 at the bottom of the positioning slot 201 drives the threaded rod to rotate through the adjustment knob 801. The height of the pressure plate is changed by the threaded transmission. The clamping force can be adjusted according to the thickness of the bottom of the electronic component to meet the fixing requirements of components of different specifications. The flip-type limiting baffle 501 is opened and closed by the hinge rotation. When closed, it can form a lateral limit on the top of the component, which, together with the longitudinal fixation of the slot, forms a three-dimensional constraint.

[0021] The bottom surface of the pallet body 101 is provided with an antistatic layer of conductive rubber and multiple metal grounding posts 1301. Each metal grounding post 1301 penetrates the antistatic layer and is welded and fixed to the metal embedded part at the bottom of the pallet body 101.

[0022] The conductive rubber antistatic layer on the bottom surface of the pallet body 101 can suppress the accumulation of static electricity through its own conductivity. At the same time, the metal grounding post 1301 penetrates the antistatic layer and is welded and fixed to the metal embedded part at the bottom of the pallet to form a conductive path, so that the static electricity generated on the pallet surface can be conducted to the ground through the grounding post to achieve static electricity release.

[0023] The through-ventilation channel 901 inside the tray is connected to the ventilation hole at the bottom of the positioning slot 201, forming an air circulation path to achieve air exchange between the inside of the slot and the outside. The openable and closable dust covers at both ends of the channel are opened when ventilating and closed when not in use to prevent dust from entering the channel and the inside of the slot.

[0024] The guide ramp 601 at the opening end of the positioning slot 201 guides the electronic component into the slot at an angle of 30°-45°. The polytetrafluoroethylene coating on the surface reduces the coefficient of sliding friction, thereby reducing resistance and wear when the component is inserted.

[0025] Furthermore, the positioning slot 201 has symmetrically distributed anti-slip ridges 1101 on both sides of its groove walls. These anti-slip ridges 1101 extend along the depth of the slot, and a guide groove is formed between adjacent anti-slip ridges 1101. The conductive rubber antistatic layer and the metal grounding post 1301 form a complete electrostatic discharge system, which can control the electrostatic voltage within a safe range, meeting the antistatic transportation requirements of electronic components (especially integrated circuits, precision sensors, etc.) and reducing the risk of electrostatic breakdown.

[0026] Furthermore, the pallet body 101 is equipped with a detachable reinforcing frame 301 along its edge. The reinforcing frame 301 engages with the edge of the pallet body 101 via a snap-fit ​​structure 1001. The reinforcing frame 301 is internally filled with honeycomb-shaped reinforcing ribs. The reinforcing frame 301 and the honeycomb-shaped reinforcing ribs increase the pallet's impact resistance by over 40%. The detachable design facilitates individual frame replacement, extending the service life of the pallet body 101. Magnetic positioning bosses 701 ensure stable connection of the frame during frequent loading and unloading, reducing structural loosening.

[0027] Furthermore, the bottom of the positioning slot 201 is provided with an adjustable elastic pressure plate 1401, and the outside of the adjustment cavity 1501 is provided with an adjustment knob 801, which is threadedly connected to the elastic pressure plate 1401 via a threaded rod. The adjustable elastic pressure plate 1401 can accommodate electronic components with large thickness differences; the angle design of the guide ramp 601 and the low-friction coating enable personnel of different skill levels to efficiently complete the loading and unloading of components, improving work efficiency.

[0028] As a further description of the above technical solution, the tray body 101 is provided with a through-type ventilation channel 901, which is connected to the vent hole at the bottom of the positioning slot 201. Both ends of the ventilation channel 901 are provided with openable and closable dust covers. The ventilation channel 901 can increase the air exchange rate inside the slot by 60%, and together with the vent hole, effectively prevents the components from oxidizing or becoming moldy due to a humid environment (relative humidity > 60%). The dust covers keep the channel clean when not in operation, reducing component cleaning costs.

[0029] Furthermore, the positioning slot 201 has a guide ramp 601 at its open end. The surface of the guide ramp 601 is coated with a polytetrafluoroethylene (PTFE) coating, and the angle between the guide ramp 601 and the wall of the positioning slot 201 is 30°-45°. The PTFE coating reduces the resistance to component insertion by 30%, the guide ramp 601 reduces alignment errors, and the snap-fit ​​type 1001 reinforcement frame 301 has a short loading and unloading time, significantly improving warehouse turnover efficiency.

[0030] Furthermore, the bottom of the reinforcing frame 301 is provided with positioning bosses 701 at the four corners, and the top of the positioning bosses 701 is provided with a magnetic adsorption layer, which is connected to the metal substrate 1201 on the bottom surface of the tray body 101.

[0031] Furthermore, the positioning slot 201 is equipped with flip-up limiting baffles 501 on both sides. These limiting baffles 501 are connected to the pallet body 101 via hinges, and a rubber buffer pad is provided on the inner side of each limiting baffle 501. The combination of the dovetail groove structure and the arc-shaped support 401 enables three-dimensional positioning of the electronic components. The anti-slip texture 1101 and the limiting baffles 501 further reduce displacement during transportation, effectively preventing damage such as component collisions and pin deformation, thus improving transportation safety.
