Description

Technical Field

[0001] This invention relates to the field of material tray technology, and in particular to a method for preparing a material tray and the material tray itself. Background Technology

[0002] Ferrite is an important component in wireless charging assemblies of existing electronic devices. This component is fragile, so a tray needs to be designed to support it in order to protect it during incoming material transportation and to meet the requirements of automated feeding.

[0003] The tray includes a foam board, and the top surface of the foam board is provided with a positioning groove for accommodating ferrite. The positioning groove is equipped with a foolproof protrusion. When the ferrite is placed in the positioning groove, the foolproof protrusion can extend into a notch on one side of the ferrite to achieve positioning of the ferrite.

[0004] After the incoming materials are transported, the ferrite needs to be removed from the material tray during assembly to wind the coil. After the ferrite is wound with the coil, it forms a finished product. The coil in the finished product covers the gap in the ferrite, causing interference with the anti-foolproof protrusion in the positioning groove. As a result, the aforementioned material tray can only be used for the incoming material transport of ferrite, and cannot be used for the positioning and transport of finished products.

[0005] To address the aforementioned issues, existing technologies have designed a tray capable of removing the anti-mistake protrusion. However, this tray is only applicable to ferrites with a single shape profile. When the shape profile of the ferrite is not distinct, or when the shape profile of the ferrite does not have a notch that matches the anti-mistake protrusion, it cannot perform anti-mistake measures, resulting in diverse shapes and inconsistent orientations of the ferrite on the tray. Summary of the Invention

[0006] The purpose of this invention is to provide a method for preparing a feed tray and a feed tray that can prevent mistakes when preparing ferrite with indistinct shape features or with gaps that do not fit the shape.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] The method for preparing the material tray includes the processing steps for the incoming material tray, which include:

[0009] S1. Set up a first foam board, process a receiving hole on the first foam board, form a positioning part and a connecting part in the receiving hole, and connect the positioning part to the hole wall of the receiving hole through the connecting part;

[0010] S2. Set a second foam board, connect the first foam board and the second foam board to form a foam support plate, and form a receiving groove under the sealing of the second foam board with the receiving hole.

[0011] S3. Remove the connecting part in the receiving hole so that the positioning part connected to the second foam board acts as a foolproof protrusion. When the ferrite is placed in the receiving groove, the foolproof protrusion extends into the center clearance structure of the ferrite.

[0012] Preferably, the processing steps for the incoming material tray after step S2 further include:

[0013] P1. Set a rigid support plate and connect it to the side of the second foam board away from the first foam board.

[0014] Preferably, the processing steps for the incoming material tray after step P1 further include:

[0015] P2. Machining positioning holes on the rigid support plate.

[0016] Preferably, step P1 is set between steps S2 and S3. In step S3, a through hole is processed on the first foam board, the second foam board and the rigid support plate connected together by a punching process. The through hole passes through the first foam board, the second foam board and the rigid support plate, the positioning part and the connecting part are divided, and the connecting part is separated from the first foam board.

[0017] Preferably, the process also includes a tray handling step, which includes:

[0018] Separate the second foam board from the rigid support plate.

[0019] Preferably, the second foam board includes a first foam layer and a second foam layer connected to each other, with the side of the first foam layer facing away from the second foam layer connected to the first foam board.

[0020] Preferably, the process also includes a finishing process for the finished tray, which includes:

[0021] The first foam layer and the second foam layer are separated, and the second foam layer is used as a cover plate. The cover plate can cover the first foam plate and seal the opening of the receiving groove.

[0022] Preferably, the process also includes a finishing process for the finished tray, which includes:

[0023] The foam tray is divided into three parts, which include two strip trays and one main tray. The main tray is located between the two strip trays. Each of the two strip trays has a row of receiving grooves, and the main tray has multiple rows of receiving grooves.

[0024] Preferably, the removal of the connecting part and the division of the foam support plate are carried out simultaneously through a punching process.

[0025] The material tray is manufactured by the above-described material tray preparation method. The material tray is provided with multiple rows of receiving slots, and each row of multiple receiving slots has a foolproof protrusion at the bottom of the slot.

[0026] The beneficial effects of this invention are:

[0027] After forming a positioning part and a connecting part in the receiving hole of the first foam board, the first foam board and the second foam board are connected to form a foam tray. Then the connecting part is removed, so that a positioning part is formed at the bottom of the receiving groove of the foam tray, spaced apart from the surrounding groove walls. The positioning part connected to the second foam board serves as a foolproof protrusion. When the ferrite is placed in the receiving groove, the foolproof protrusion extends into the center clearance structure of the ferrite, thereby achieving the positioning of the ferrite. This avoids the problem of interference between the foolproof protrusion and the coil subsequently wound on the ferrite when the foolproof design is based on the outer contour. This allows the tray to be used for both the positioning and transportation of incoming materials and the positioning and transportation of finished products. It can adapt to ferrites with various outer contours, reducing the cost of use and improving the efficiency of use. Attached Figure Description

[0047] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] Example 1

[0049] like Figures 1-8 As shown, this embodiment provides a method for preparing a material tray, including a material tray processing step, which includes:

[0050] S1. A first foam board 1 is provided, and a receiving hole 11 is processed on the first foam board 1. A positioning part 12 and a connecting part 13 are formed in the receiving hole 11. The positioning part 12 is connected to the hole wall of the receiving hole 11 through the connecting part 13.

[0051] S2. Set a second foam board 2, connect the first foam board 1 and the second foam board 2 to form a foam support plate 100, and form a receiving groove 101 under the sealing of the second foam board 2.

[0052] S3. Remove the connecting part 13 in the receiving hole 11 so that the positioning part 12 connected to the second foam board 2 serves as a foolproof protrusion. When the ferrite is placed in the receiving groove 101, the foolproof protrusion extends into the center clearance structure of the ferrite.

[0053] In the preparation method of the material tray of the present invention, after forming a positioning part 12 and a connecting part 13 in the receiving hole 11 of the first foam plate 1, the first foam plate 1 and the second foam plate 2 are connected to form a foam support plate. Then the connecting part 13 is removed, so that a positioning part 12 spaced apart from the surrounding groove wall is formed at the bottom of the receiving groove 101 of the foam support plate. The positioning part 12 connected to the second foam plate 2 serves as a foolproof protrusion. When the ferrite is placed in the receiving groove 101, the foolproof protrusion extends into the center clearance structure of the ferrite, thereby realizing the positioning of the ferrite. This avoids the problem of interference between the foolproof protrusion and the coil subsequently wound on the ferrite when the foolproof design is carried out from the outer contour. This allows the material tray to be used for the positioning and transportation of incoming materials as well as the positioning and transportation of finished products. It can adapt to ferrites with various outer contours, reduce the cost of use, and improve the efficiency of use.

[0054] Specifically, the processing steps of the incoming material tray after step S2 also include: P1, setting a rigid support plate 200, and connecting the rigid support plate 200 to the side of the second foam board 2 away from the first foam board 1. By setting the rigid support plate 200, the load-bearing capacity of the foam support plate 100 is improved, avoiding the technical problem that the soft foam support plate 100 is prone to deformation under load.

[0055] In this embodiment, the rigid tray 200 is made of PET, and its length and width are greater than those of the foam tray 100, respectively. In other embodiments, the rigid tray 200 may also be made of other types of rigid plastics.

[0056] Specifically, the processing steps for the incoming material tray, after step P1, also include: P2, machining positioning holes 201 on the rigid pallet 200. Machining positioning holes 201 facilitates the positioning and placement of the material tray on subsequent carrying and transport equipment.

[0057] In this embodiment, two positioning holes 201 are machined at each end of the rigid support plate 200 along its length. In other embodiments, the position and number of positioning holes 201 can be set according to actual needs.

[0058] Specifically, step P1 is positioned between steps S2 and S3. In step S3, a through hole 300 is formed in the connected first foam board 1, second foam board 2, and rigid support plate 200 using a punching process. The through hole 300 penetrates the first foam board 1, second foam board 2, and rigid support plate 200, dividing the positioning part 12 and the connecting part 13, and separating the connecting part 13 from the first foam board 1. In the above arrangement, multiple connecting parts 13 are simultaneously cut and peeled off using a punching process, resulting in high processing efficiency.

[0059] In this embodiment, steps P1 and P2 are performed sequentially between steps S2 and S3. In other embodiments, step P2 may be performed after step S3.

[0060] Specifically, the preparation method of the material tray also includes a finished product tray processing step, which includes dividing the foam tray 100 into three parts. These three parts include two strip trays 102 and one main tray 103. The main tray 103 is located between the two strip trays 102. Each of the two strip trays 102 has a row of receiving grooves 101, and the main tray 103 has multiple rows of receiving grooves 101. This configuration allows the finished product tray to be adapted to existing production lines, reducing processing and design costs.

[0061] More specifically, the removal of the connecting portion 13 and the segmentation of the foam support plate 100 are carried out simultaneously through a punching process. This arrangement improves processing efficiency and reduces processing costs.

[0062] In this embodiment, the processing steps for the finished product tray are set after the processing steps for the incoming material tray, according to the requirements of the usage stage.

[0063] Specifically, the preparation method of the tray also includes a tray processing step, which includes separating the second foam board 2 and the rigid support plate 200. Since the second foam board 2 and the rigid support plate 200 are made of different materials, separating them before processing reduces processing costs.

[0064] In this embodiment, the material tray processing step is set after the finished product tray processing step according to the needs of the usage stage, so that when the second foam board 2 and the rigid tray 200 are separated, the main tray 103 and the two strip trays 102 on the rigid tray 200 are automatically separated, and the user can take the main tray 103 as needed.

[0065] like Figure 9 As shown, based on the entire usage and processing cycle of the tray, the tray preparation method provided in this embodiment specifically includes the following steps:

[0066] Step 1: Set up the first foam board 1 and machine the receiving hole 11 on the first foam board 1.

[0067] In this step, pressure-sensitive adhesive is laid on one side of the first foam board 1, which has a thickness of 2mm.

[0068] like Figure 2 As shown, eleven rows of receiving holes 11 are formed on the first foam board 1 by punching. Among the eleven rows of receiving holes 11, the spacing between the first and second rows and the spacing between the tenth and eleventh rows are the same, and the spacing between the remaining nine middle rows is the same, so that the middle foam still has skirts at the top and bottom when it is peeled off.

[0069] On the first foam board 1, a positioning part 12 and a connecting part 13 are formed in the receiving hole 11. The positioning part 12 is connected to the hole wall of the receiving hole 11 through the connecting part 13.

[0070] Step 2: Set up the second foam board 2, and connect the first foam board 1 and the second foam board 2 to form a foam support plate 100.

[0071] In this step, AB glue is laid on one side of the second foam board 2, which has a thickness of 3mm.

[0072] Remove the release paper from the pressure-sensitive adhesive on the first foam board 1, and then bond the first foam board 1 and the second foam board 2 together using pressure-sensitive adhesive. Press the two together to ensure the quality of the connection.

[0073] like Figure 3 As shown, after the connection is completed, the receiving hole 11 forms a receiving groove 101 under the sealing of the second foam plate 2.

[0074] Step 3: Set up the rigid support plate 200 and connect the rigid support plate 200 to the side of the second foam board 2 away from the first foam board 1.

[0075] like Figure 1 As shown, in this step, the release paper of the AB glue on the second foam board 2 is removed, and the second foam board 2 and the rigid support plate 200 with a thickness of 0.4mm are bonded together by AB glue.

[0076] Step 4: Machining positioning holes 201 on the rigid support plate 200.

[0077] like Figure 4 As shown, in this step, the shape of the 0.4mm thick rigid pallet 200 is punched. When punching the rigid pallet 200, four positioning holes 201 are punched at both ends of its length for subsequent positioning.

[0078] Step 5: Remove the connecting part 13 in the receiving hole 11, and punch out the outline of the main body tray 103 on the foam tray 100 to obtain the material tray.

[0079] In this step, a through hole 300 is processed through the first foam board 1, the second foam board 2 and the rigid support plate 200 connected together by a punching process. The through hole 300 passes through the first foam board 1, the second foam board 2 and the rigid support plate 200, and divides the positioning part 12 and the connecting part 13.

[0080] like Figure 5 and Figure 6 As shown, after the positioning part 12 and the connecting part 13 are separated, the product is placed on a device through the positioning hole 201 processed in step four. The connecting part 13, which is punched out in the receiving groove 101, is separated from the first foam board 1. Finally, the positioning part 12, which is connected to the second foam board 2 alone, acts as a foolproof protrusion. When the ferrite is received in the receiving groove 101, the foolproof protrusion extends into the center clearance structure of the ferrite.

[0081] like Figure 5 As shown, the foam pallet 100 is divided into three parts by punching. The three parts include two strip pallets 102 and one main pallet 103. The main pallet 103 is located between the two strip pallets 102. Each of the two strip pallets 102 is provided with a row of receiving grooves 101, and the main pallet 103 is provided with nine rows of receiving grooves 101.

[0082] The product processed in this step serves as the ferrite feed tray, and the positioning part 12 is used to position the ferrite.

[0083] Step 6: Separate the second foam board 2 and the rigid support plate 200.

[0084] like Figure 7 and Figure 8 As shown, in this step, when the second foam board 2 and the rigid tray 200 are separated, the main tray 103 and the two strip trays 102 on the rigid tray 200 are automatically separated, and the user can take the main tray 103 as needed.

[0085] Step 7: Using the main tray 103 as the finished product tray, separate the rigid tray 200 and the two strip trays 102 for further processing.

[0086] After the material tray is used up, the rigid pallet 200 is peeled off from the foam pallet 100, thereby automatically separating the main pallet 103 and the two strip pallets 102 that have been cut and separated. The main pallet 103 can be used as a finished product tray to carry finished products, while the remaining rigid pallet 200 and the two strip pallets 102 are processed separately, without increasing the cost of waste disposal.

[0087] Example 2

[0088] This embodiment provides a method for preparing a material tray, which differs from Embodiment 1 in that: the second foam board 2 includes a first foam layer and a second foam layer connected to each other, with the side of the first foam layer facing away from the second foam layer connected to the first foam board 1. This configuration allows for greater flexibility and adaptability in the thickness of the second foam board 2.

[0089] More specifically, the processing steps of the finished tray also include: separating the first foam layer and the second foam layer, using the second foam layer as a cover plate, which can cover the first foam board 1 and seal the opening of the receiving groove 101. In the above arrangement, the layered structure of the second foam board 2 is fully utilized, and a part of the second foam board 2 is used as a cover plate, making the finished tray more secure and reliable in supporting the finished product.

[0090] like Figure 10 As shown, the preparation method of the material tray in this embodiment specifically includes the following steps:

[0091] Step 1: Set up the first foam board 1 and machine the receiving hole 11 on the first foam board 1.

[0092] In this step, pressure-sensitive adhesive is laid on one side of the first foam board 1, which has a thickness of 2mm.

[0093] like Figure 2 As shown, eleven rows of receiving holes 11 are formed on the first foam board 1 by punching. Among the eleven rows of receiving holes 11, the spacing between the first and second rows and the spacing between the tenth and eleventh rows are the same, and the spacing between the remaining nine middle rows is the same, so that the middle foam still has skirts at the top and bottom when it is peeled off.

[0094] On the first foam board 1, a positioning part 12 and a connecting part 13 are formed in the receiving hole 11. The positioning part 12 is connected to the hole wall of the receiving hole 11 through the connecting part 13.

[0095] Step 2: Set up the second foam board 2, and connect the first foam board 1 and the second foam board 2 to form a foam support plate 100.

[0096] In this step, AB glue is laid on one side of the second foam board 2, which has a thickness of 3mm.

[0097] Remove the release paper from the pressure-sensitive adhesive on the first foam board 1, and then bond the first foam board 1 and the second foam board 2 together using pressure-sensitive adhesive. Press the two together to ensure the quality of the connection.

[0098] like Figure 3 As shown, after the connection is completed, the receiving hole 11 forms a receiving groove 101 under the sealing of the second foam plate 2.

[0099] Step 3: Set up the rigid support plate 200 and connect the rigid support plate 200 to the side of the second foam board 2 away from the first foam board 1.

[0100] like Figure 1 As shown, in this step, the release paper of the AB glue on the second foam board 2 is removed, and the second foam board 2 and the rigid support plate 200 with a thickness of 0.4mm are bonded together by AB glue.

[0101] Step 4: Machining positioning holes 201 on the rigid support plate 200.

[0102] like Figure 4 As shown, in this step, the shape of the 0.4mm thick rigid pallet 200 is punched. When punching the rigid pallet 200, four positioning holes 201 are punched at both ends of its length for subsequent positioning.

[0103] Step 5: Remove the connecting part 13 in the receiving hole 11, and punch out the outline of the main body tray 103 on the foam tray 100 to obtain the material tray.

[0104] In this step, a through hole 300 is processed through the first foam board 1, the second foam board 2 and the rigid support plate 200 connected together by a punching process. The through hole 300 passes through the first foam board 1, the second foam board 2 and the rigid support plate 200, and divides the positioning part 12 and the connecting part 13.

[0105] like Figure 5 and Figure 6 As shown, after the positioning part 12 and the connecting part 13 are separated, the product is placed on a device through the positioning hole 201 processed in step four. The connecting part 13, which is punched out in the receiving groove 101, is separated from the first foam board 1. Finally, the positioning part 12, which is connected to the second foam board 2 alone, acts as a foolproof protrusion. When the ferrite is received in the receiving groove 101, the foolproof protrusion extends into the center clearance structure of the ferrite.

[0106] like Figure 5As shown, the foam pallet 100 is divided into three parts by punching. The three parts include two strip pallets 102 and one main pallet 103. The main pallet 103 is located between the two strip pallets 102. Each of the two strip pallets 102 is provided with a row of receiving grooves 101, and the main pallet 103 is provided with nine rows of receiving grooves 101.

[0107] The product processed in this step serves as the ferrite feed tray, and the positioning part 12 is used to position the ferrite.

[0108] Step 6: Separate the second foam board 2 and the rigid support plate 200.

[0109] like Figure 7 and Figure 8 As shown, in this step, when the second foam board 2 and the rigid tray 200 are separated, the main tray 103 and the two strip trays 102 on the rigid tray 200 are automatically separated, and the user can take the main tray 103 as needed.

[0110] Step 7: Using the main tray 103 as the finished product tray, separate the rigid tray 200 and the two strip trays 102 for further processing.

[0111] After the material tray is used up, the rigid pallet 200 is peeled off from the foam pallet 100, thereby automatically separating the main pallet 103 and the two strip pallets 102 that have been cut and separated. The main pallet 103 can be used as a finished product tray to carry finished products, while the remaining rigid pallet 200 and the two strip pallets 102 are processed separately, without increasing the cost of waste disposal.

[0112] Step 8: For the main support plate 103, separate the first foam layer and the second foam layer, and use the second foam layer as a cover plate.

[0113] In this step, the first foam layers in the first foam board 1 and the second foam board 2 in the main body tray 103 are connected to each other to support the finished product. The second foam layer in the second foam board 2 is peeled off from the main body tray 103 and serves as a cover plate to seal the opening of the receiving groove 101, making the placement of the finished product safer and more reliable.

[0114] Example 3

[0115] This embodiment provides a material tray, which is manufactured by the material tray preparation method in any of the above embodiments. The material tray is provided with multiple rows of receiving grooves 101, and each row of multiple receiving grooves 101 has a foolproof protrusion at the bottom of the groove.

[0116] In the material tray of the present invention, after a positioning part 12 and a connecting part 13 are formed in the receiving hole 11 of the first foam plate 1, the first foam plate 1 and the second foam plate 2 are connected to form a foam support plate 100. Then the connecting part 13 is removed, so that a positioning part 12 spaced apart from the surrounding groove wall is formed at the bottom of the receiving groove 101 of the foam support plate 100. The positioning part 12 connected to the second foam plate 2 serves as a foolproof protrusion. When the ferrite is placed in the receiving groove 101, the foolproof protrusion extends into the center clearance structure of the ferrite, thereby realizing the positioning of the ferrite. This avoids the problem of interference between the foolproof protrusion and the coil subsequently wound on the ferrite when the foolproof design is based on the outer contour. This allows the material tray to be used for both the positioning and transportation of incoming materials and the positioning and transportation of finished products. It can adapt to ferrites with various outer contours, reducing the cost of use and improving the efficiency of use.

[0117] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
