Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vacuum coating, in particular to a carrier. BACKGROUND

[0002] In the production process of battery pieces, the substrate will be transported between multiple processing stations. Specifically, the substrate is placed on the carrier, and the carrier sequentially passes through multiple processing stations. At each processing station, the substrate is processed to ultimately form a battery piece.

[0003] In the related art, the carrier includes a carrier frame and a carrier plate. The carrier frame is in a mesh shape, and the carrier plate is fixed to the carrier frame. The carrier frame provides support for the carrier plate. Multiple grooves are formed on the carrier plate, and the substrate is placed in the grooves. Since the carrier is divided into two parts, the carrier frame and the carrier plate, the structure is complex, and the processing and assembly are also complex. UTILITY MODEL CONTENT

[0004] The present application provides a carrier for providing a carrier with a simple structure, which is easy to process and assemble.

[0005] The present application provides a carrier. The carrier includes a frame and multiple inner frame strips. The multiple inner frame strips are arranged in the frame. The end of the inner frame strip is connected to the frame. The multiple inner frame strips are arranged in the plane of the frame to form multiple bearing holes. The bearing holes are used to accommodate the substrate. The multiple inner frame strips have bearing protrusions in the bearing holes. Along the circumference of the bearing hole, the multiple bearing protrusions in the same bearing hole are sequentially arranged. The upper end surface of the multiple bearing protrusions is used to bear the substrate, so that the substrate is accommodated in the bearing hole.

[0006] In the carrier provided by the present application, the frame provides a mounting space for the inner frame strips. The multiple inner frame strips are arranged in the plane of the frame to form multiple bearing holes, thereby forming the carrier. Since the multiple bearing protrusions in the bearing holes are formed on the inner frame strips, the substrate can be placed on the upper end surface of the bearing protrusions, thereby achieving the bearing of the substrate and the synchronous conveying of the carrier and the substrate. Since the bearing holes for accommodating the substrate are directly formed by the multiple inner frame strips, and the bearing protrusions for bearing the substrate are directly formed on the inner frame strips, the carrier has a simple structure and is easy to process and assemble.

[0007] In one possible implementation of the present application, the upper end surface of the bearing protrusion is an inclined surface. The inclined surface forms an acute angle with the axial direction of the bearing hole. Along the axial direction of the bearing hole, the edge of the inclined surface close to the center line of the bearing hole is lower than the edge of the inclined surface away from the center line of the bearing hole.

[0008] In this way, the substrate and the inclined surface are in linear contact, and during the conveying of the carrier, the substrate and the inclined surface are in linear friction, so that the abrasion degree of the lower surface of the substrate is reduced.

[0009] In a possible implementation of the present application, the edge of the inclined surface away from the center line of the bearing hole is flush with the upper surface of the inner frame strip. The carrier further comprises a limiting piece arranged on the upper surface of the inner frame strip and away from the edge of the inclined surface away from the center line of the bearing hole, and the limiting piece is arranged to avoid the bearing hole and is connected to the inner frame strip.

[0010] Through the above arrangement, when the substrate is placed on the inclined surface, the limiting piece can limit the substrate, so that the substrate is prevented from moving out of the inclined surface, and the substrate is stably arranged in the bearing hole.

[0011] In a possible implementation of the present application, the limiting piece comprises a plurality of limiting protrusions arranged in sequence and spaced apart away from the edge of the inclined surface away from the center line of the bearing hole.

[0012] Through the arrangement of the limiting piece in the form of a plurality of limiting protrusions, since the plurality of limiting protrusions are arranged in sequence and spaced apart away from the edge of the inclined surface away from the center line of the bearing hole, the normal implementation of the limiting function of the limiting protrusions can be ensured, and the material of the limiting piece can be reduced, thereby reducing the material cost.

[0013] In a possible implementation of the present application, the plurality of inner frame strips arranged in cross form a plurality of cross positions, and the cross position is formed by two inner frame strips, the two inner frame strips comprising a first inner frame strip and a second inner frame strip, and the first inner frame strip and the second inner frame strip are arranged in sequence in a direction perpendicular to the plane of the frame. At the cross position, the side of the second inner frame strip opposite to the first inner frame strip has an avoiding groove, the avoiding groove penetrates the second inner frame strip in the extension direction of the first inner frame strip, and the first inner frame strip partially extends into the avoiding groove.

[0014] In this way, the assembly of the first inner frame strip and the second inner frame strip is facilitated, and the groove depth of the avoiding groove can be reasonably set so that the upper end surfaces of the first inner frame strip and the second inner frame strip are located in the same plane, so that the surface of the mesh structure formed by the plurality of inner frame strips is flat, thereby facilitating the arrangement of the bearing protrusions and the placement of the substrate.

[0015] In a possible implementation of the present application, the carrier further comprises a pressing piece arranged at the cross position, and the pressing piece comprises a connecting portion and a pressing portion, the connecting portion penetrates the first inner frame strip and is connected to the second inner frame strip in the arrangement direction of the first inner frame strip and the second inner frame strip, and the pressing portion is connected to one end of the connecting portion away from the second inner frame strip and abuts against the first inner frame strip. The pressing portion avoids the bearing hole.

[0016] Through the above arrangement, the crimping piece is connected to the first inner frame strip and the second inner frame strip through the connecting part. Due to the presence of the pressing part, the pressing part can press the first inner frame strip on the second inner frame strip. Thus, during the transportation of the carrier, the relative stability between the first inner frame strip and the second inner frame strip can be ensured, the vibration frequency between the first inner frame strip and the second inner frame strip is reduced, and thus the structural stability of the whole carrier is ensured.

[0017] In a possible implementation manner of the present application, the side of the first inner frame strip away from the second inner frame strip has a receiving groove, and the pressing part is located in the receiving groove.

[0018] By arranging the receiving groove on the first inner frame strip, the receiving groove can provide accommodation space for the pressing part. Thus, by reasonably arranging the groove depth of the receiving groove, the upper surface of the pressing part is close to or flush with the upper surface of the first inner frame strip, so as to avoid the influence of the presence of the pressing part on the surface flatness of the whole carrier.

[0019] In a possible implementation manner of the present application, the end of the inner frame strip is connected to the frame through a first mortise and tenon structure; and / or, the frame comprises a plurality of outer frame strips connected in sequence in a head-to-tail manner, and adjacent outer frame strips are connected through a second mortise and tenon structure.

[0020] Thus, the connection between the inner frame strip and the frame can be smooth, and the connection mode is also relatively simple and has high connection stability. And / or, the connection between the adjacent outer frame strips can be smooth, and the connection mode is also relatively simple and has high connection stability.

[0021] In a possible implementation manner of the present application, the carrier further comprises a connecting piece. The connecting corner of the connection between the inner frame strip and the frame is provided with a connecting piece, and the connecting piece is connected to the frame and the inner frame strip respectively; and / or, the corner of the frame is provided with a connecting piece, and the connecting piece is connected to the two outer frame strips of the frame at the corner respectively.

[0022] Through the above arrangement, the connecting piece can be connected to the frame and the inner frame strip respectively at the connecting corner of the connection between the end of the inner frame strip and the frame, so as to increase the structural strength of the connecting corner of the connection between the end of the inner frame strip and the frame. And / or, the connecting piece can be connected to the two outer frame strips of the frame at the corner of the frame respectively, so as to increase the structural strength of the corner of the frame.

[0023] In a possible implementation manner of the present application, the plurality of inner frame strips comprise a plurality of first inner frame strips and a plurality of second inner frame strips. The plurality of first inner frame strips are arranged in sequence in a first direction with intervals, and the first inner frame strip extends in a second direction. The plurality of second inner frame strips are arranged in sequence in the second direction with intervals, and the second inner frame strip extends in the first direction. The first direction intersects with the second direction. The plurality of first inner frame strips and the plurality of second inner frame strips are arranged in a cross manner to enclose a plurality of bearing holes.

[0024] Through the above setting, the plurality of first inner frame strips and the plurality of second inner frame strips are arranged in an array, so that more inner frame strips can be arranged in the limited space inside the frame, and more substrates can be placed, thereby improving the substrate carrying rate per unit area of the carrier. In addition, the first inner frame strips and the second inner frame strips arranged in this way can also be produced and assembled with the carrier, thereby reducing the processing difficulty of the carrier.

The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

Rather, the use of the words such as "exemplary" or "for example" is intended to present concepts in a concrete manner.

[0048] In the production process of battery pieces, the transmission of substrates between multiple processing stations is involved. In order to facilitate the transportation of the substrates, the substrates are generally placed on a carrier, and the carrier sequentially passes through multiple processing stations. At each processing station, the substrates on the carrier are processed to ultimately form battery pieces.

[0049] In the related art, the carrier is composed of a metal carrier frame and a metal carrier plate. Specifically, the metal carrier frame includes a frame and a metal wire mesh arranged inside the frame, and the metal carrier plate is placed on the metal wire mesh, and then a groove is processed on the metal carrier plate to carry the substrate. Since such a carrier is divided into a metal carrier frame and a metal carrier plate, the structure is complex, and the processing and assembly are also complex.

[0050] Based on this, as shown in the drawings, the present application provides a carrier 01, which includes a frame 1 and a plurality of inner frame strips 2. The plurality of inner frame strips 2 are arranged inside the frame 1, the end of the inner frame strip 2 is connected with the frame 1, and the plurality of inner frame strips 2 are arranged in cross in the plane of the frame 1 to enclose a plurality of bearing holes a, and the bearing holes a are used to accommodate the substrate 02. The plurality of inner frame strips 2 have bearing protrusions 21 located in the bearing holes a, and the plurality of bearing protrusions 21 in the same bearing hole a are sequentially arranged along the circumference of the bearing hole a, and the upper end surface 21a of the plurality of bearing protrusions 21 is used to carry the substrate 02, so that the substrate 02 is accommodated in the bearing hole a. Figures 1-3 Based on this, as shown in the drawings, the present application provides a carrier 01, which includes a frame 1 and a plurality of inner frame strips 2. The plurality of inner frame strips 2 are arranged inside the frame 1, the end of the inner frame strip 2 is connected with the frame 1, and the plurality of inner frame strips 2 are arranged in cross in the plane of the frame 1 to enclose a plurality of bearing holes a, and the bearing holes a are used to accommodate the substrate 02. The plurality of inner frame strips 2 have bearing protrusions 21 located in the bearing holes a, and the plurality of bearing protrusions 21 in the same bearing hole a are sequentially arranged along the circumference of the bearing hole a, and the upper end surface 21a of the plurality of bearing protrusions 21 is used to carry the substrate 02, so that the substrate 02 is accommodated in the bearing hole a.

[0051] It can be understood that the upper and lower of the carrier 01 refer to the side of the carrier 01 away from the conveying line as the upper side and the side of the carrier 01 close to the conveying line as the lower side after the carrier 01 is placed on the conveying line. On this basis, the substrate 02 is located on the upper side of the carrier 01, and thus the upper end surface 21a of the bearing protrusion 21 is the surface of the bearing protrusion 21 away from the conveying line.

[0052] The outer contour of the frame 1 can be a regular shape such as a circle or a square. Of course, the outer contour of the frame 1 can also be an irregular shape.

[0053] In addition, the material of the frame 1 can be a composite material, metal, or plastic, etc. For example, the composite material can be carbon fiber, etc., and the frame 1 made of carbon fiber material has the advantages of high structural strength, light weight, corrosion resistance, etc. The material of the inner frame strip 2 can be a composite material, metal, or plastic, etc. For example, the composite material can be carbon fiber, etc., and the inner frame strip 2 made of carbon fiber material has the advantages of high structural strength, light weight, corrosion resistance, etc.

[0054] In some examples, along the circumferential direction of the bearing hole a, any two adjacent bearing protrusions 21 in the same bearing hole a can be arranged in contact with each other. Of course, along the circumferential direction of the bearing hole a, the plurality of bearing protrusions 21 in the same bearing hole a can be arranged at intervals. The number of bearing protrusions 21 in the same bearing hole a can be two, three, or four, etc., and can be set according to requirements.

[0055] In some examples, the bearing hole a can be a regular shape such as a circular hole or a square hole, or can also be an irregularly shaped space as long as it can accommodate the substrate 02.

[0056] In some examples, along the extension direction of the bearing hole a, the size of the bearing protrusion 21 is consistent with the size of the inner frame strip 2 where the bearing protrusion 21 is located, that is, along the extension direction of the bearing hole a, the bearing protrusion 21 extends from one end of the inner frame strip 2 where the bearing protrusion 21 is located to the other end.

[0057] Of course, along the extension direction of the bearing hole a, the size of the bearing protrusion 21 can also be smaller than the size of the bearing hole a.

[0058] In some examples, the bearing protrusion 21 and the inner frame strip 2 are an integral structure, which not only can ensure the structural strength between the bearing protrusion 21 and the inner frame strip 2, but also can avoid secondary processing.

[0059] In some examples, the cross section of the inner frame strip 2 perpendicular to the extension direction thereof can be a regular shape such as a square or a circle, or can be an irregular shape.

[0060] Through the above arrangement, the frame 1 provides mounting space for the inner frame strips 2, and the plurality of inner frame strips 2 are arranged in cross in the plane of the frame 1 to enclose a plurality of bearing holes a, thereby forming the carrier 01. Since the plurality of bearing protrusions 21 located in the bearing holes a are formed on the inner frame strips 2, the substrate 02 can be placed on the upper end surface 21a of the bearing protrusion 21 to achieve the bearing of the substrate 02, and further to achieve the synchronous conveying of the carrier 01 and the substrate 02.

[0061] Since the bearing holes a for accommodating the substrates 02 are directly enclosed by the plurality of inner frame strips 2 in cross, and the bearing protrusions 21 for bearing the substrates 02 are directly formed on the inner frame strips, the carrier 01 in the present application has a simple structure, and is convenient to process and assemble.

[0062] In order to facilitate the processing of the carrier 01, and at the same time facilitate the bearing of more substrates 02, the cross arrangement of the plurality of inner frame strips 2 needs to be designed accordingly.

[0063] In some embodiments, as shown in Figures 1-3 The plurality of inner frame strips 2 include a plurality of first inner frame strips 2A and a plurality of second inner frame strips 2B. The plurality of first inner frame strips 2A are arranged in cross along the first direction X and the second direction Y. The plurality of second inner frame strips 2B are arranged in cross along the second direction Y and the first direction X. The plurality of first inner frame strips 2A and the plurality of second inner frame strips 2B are arranged in cross to enclose the plurality of bearing holes a.

[0064] It can be understood that the distance between adjacent first inner frame strips 2A should be determined according to the size of the substrate 02 in the first direction X. Similarly, the distance between adjacent second inner frame strips 2B should be determined according to the size of the substrate 02 in the second direction Y. In addition, it can be known that one bearing hole a is enclosed by two first inner frame strips 2A and two second inner frame strips 2B.

[0065] In some examples, the angle between the first direction X and the second direction Y can be 80°, 90°, 100°, or 110°, etc.

[0066] In some examples, as shown in Figures 1-3As shown, the first direction X is perpendicular to the second direction Y. The frame 1 is in a square structure, and the frame 1 comprises four outer frame strips 11 connected in sequence and end to end, and the four outer frame strips 11 comprise two first outer frame strips 11A arranged opposite to each other and two second outer frame strips 11B arranged opposite to each other, the first outer frame strips 11A extend along the first direction X, the second outer frame strips 11B extend along the second direction Y, and the first outer frame strips 11A and the second outer frame strips 11B are arranged perpendicular to each other. In this way, the entire carrier 01 is in a square mesh shape, and the overall structure is regularized, which can facilitate the production, processing and assembly of the frame 1 and the inner frame strips 2.

[0067] In some examples, the size of the first inner frame strip 2A and the second inner frame strip 2B can be consistent or inconsistent along the extension direction of the bearing hole a.

[0068] Through the above arrangement, the plurality of first inner frame strips 2A and the plurality of second inner frame strips 2B are arranged in an array, which can facilitate the arrangement of more inner frame strips 2 in the limited space inside the frame 1, can facilitate the placement of more substrates 02, and improve the substrate 02 carrying rate per unit area of the carrier 01. In addition, the first inner frame strip 2A and the second inner frame strip 2B arranged in this way can also be produced by itself and assembled into the carrier 01, which reduces the processing difficulty of the carrier 01.

[0069] Of course, the plurality of inner frame strips 2 can also be arranged in any other suitable manner.

[0070] For the convenience of the drawings, the drawings in the present application will be illustrated by taking the plurality of inner frame strips 2 comprising the first inner frame strip 2A and the second inner frame strip 2B, and the first direction X and the second direction Y being perpendicular as an example.

[0071] After the substrate 02 is placed on the bearing protrusion 21, in order to enable the substrate 02 to be stably positioned in the bearing hole a, the surface of the bearing protrusion 21 for bearing the substrate 02 can be an inclined surface or a flat surface, etc. The following will be described in detail.

[0072] In some embodiments, as shown in Figure 4 , Figure 5 The upper end surface of the bearing protrusion 21 is an inclined surface, the inclined surface forms an acute angle with the axial direction of the bearing hole a, and along the axial direction of the bearing hole a, the edge of the inclined surface close to the center line of the bearing hole a is lower than the edge of the inclined surface away from the center line of the bearing hole a.

[0073] The inclined surface can be a flat surface. Alternatively, the inclined surface can also be a curved surface, for example, the inclined surface can be a downwardly concave curved surface or an upwardly convex curved surface.

[0074] In some examples, as shown in Figure 5 , Figure 6As shown, the inner frame strip 2 is a cuboid strip structure, the edge of the inclined surface away from the center line of the bearing hole a coincides with the upper side edge of the cuboid strip structure, so that by reasonably setting the inclination angle of the inclined surface, after the substrate 02 is accommodated in the bearing hole a, the substrate 02 can be prevented from being placed too deep, and the substrate 02 can be conveniently taken and placed.

[0075] Of course, as Figure 7 shown, the edge of the inclined surface away from the center line of the bearing hole a can also be lower than the uppermost end of the inner frame strip 2.

[0076] By setting the upper end surface 21a of the bearing protrusion 21 as an inclined surface, so that after the substrate 02 is placed on the inclined surface, the substrate 02 is in line contact with the inclined surface, and during the conveying of the carrier 01, the substrate 02 and the inclined surface are in line friction, so that the wear degree of the lower surface of the substrate 02 can be reduced, the integrity of the substrate 02 is guaranteed, and the structural integrity of the battery piece finally produced after the substrate 02 is coated is guaranteed.

[0077] Of course, in other embodiments, as Figure 8 shown, the upper end surface 21a of the bearing protrusion 21 can also be a plane, and the upper end surface 21a of the bearing protrusion 21 is lower than the uppermost end of the inner frame strip 2, so that the substrate 02 can be stably accommodated in the bearing hole a.

[0078] In some embodiments, as Figure 9 shown, the edge of the inclined surface away from the center line of the bearing hole a is flush with the upper surface of the inner frame strip 2. The carrier 01 further comprises a limiting piece 3, which is arranged on the upper surface of the inner frame strip 2 and along the edge of the inclined surface away from the center line of the bearing hole a, and avoids the bearing hole a, and the limiting piece 3 is connected with the inner frame strip 2.

[0079] In some examples, one bearing hole a is surrounded by two first inner frame strips 2A and two second inner frame strips 2B, and the two first inner frame strips 2A and the two second inner frame strips 2B each have a bearing protrusion 21, so that each bearing hole a has four bearing protrusions 21, and the upper end surface 21a of each bearing protrusion 21 is an inclined surface, and the edge of the inclined surface away from the center line of the bearing hole a is flush with the upper surface of the first inner frame strip 2A and the second inner frame strip 2B, so that the limiting piece 3 can be arranged along the edges of the inclined surfaces away from the center line of the bearing hole a, that is, the limiting piece 3 is arranged along the circumference of the bearing hole a. In this way, when the substrate 02 is placed on the inclined surface, the existence of the limiting piece 3 can limit the position of the substrate 02, so as to avoid the substrate 02 from being greatly deviated in the horizontal direction due to the inclination of the substrate 02 on the inclined surface, and to ensure that the substrate 02 is stably arranged in the bearing hole a.

[0080] Through the above setting, since the limiting piece 3 is arranged along the edge of the inclined surface away from the center line of the bearing hole a, when the substrate 02 is placed on the inclined surface, the limiting piece 3 can limit the substrate 02, avoiding the substrate 02 from moving out of the inclined surface, so that the substrate 02 is stably arranged in the bearing hole a.

[0081] On this basis, in some embodiments, as shown in Figure 9 , the limiting piece 3 includes a plurality of limiting protrusions 31, which are sequentially and spacedly arranged along the edge of the inclined surface away from the center line of the bearing hole a.

[0082] In some examples, one bearing hole a is surrounded by two first inner frame strips 2A and two second inner frame strips 2B, and the first inner frame strip 2A and the second inner frame strip 2B are perpendicular to each other, the edge of the inclined surface of one bearing protrusion 21 away from the center line of the bearing hole a corresponds to two limiting protrusions 31, and the two limiting protrusions 31 are respectively located near the two ends of the edge of the inclined surface away from the center line of the bearing hole a, so that the top corner of one substrate 02 corresponds to the two limiting protrusions 31, so that the limiting protrusions 31 can limit the substrate 02 while reducing the number of limiting protrusions 31.

[0083] Among them, the limiting protrusion 31 can be a columnar structure, for example, it can be a cylindrical structure or a square columnar structure, etc.

[0084] By setting the limiting piece 3 to a plurality of limiting protrusions 31, since the plurality of limiting protrusions 31 are sequentially and spacedly arranged along the edge of the inclined surface away from the center line of the bearing hole a, the normal implementation of the limiting function of the limiting protrusions 31 can be ensured, and the material of the limiting piece 3 can be reduced, and the material cost can be reduced.

[0085] In other embodiments, the limiting piece 3 can also be arranged along the edge of the inclined surface away from the center line of the bearing hole a.

[0086] In some embodiments, as shown in Figure 10 , Figure 11 , the plurality of inner frame strips 2 arranged in cross form are formed with a plurality of cross positions, the cross position is formed by two inner frame strips 2, the two inner frame strips 2 include the first inner frame strip 2A and the second inner frame strip 2B, and the first inner frame strip 2A and the second inner frame strip 2B are sequentially arranged along the direction perpendicular to the plane where the frame 1 is located. At the cross position, the side of the second inner frame strip 2B opposite to the first inner frame strip 2A has an avoiding slot b, the avoiding slot b penetrates the second inner frame strip 2B along the extension direction of the first inner frame strip 2A, and the first inner frame strip 2A partially extends into the avoiding slot b.

[0087] It can be understood that by arranging the avoiding slot b, the first inner frame strip 2A and the second inner frame strip 2B can be located in the same plane, and the plurality of inner frame strips 2 arranged in cross in the plane where the frame 1 is located will not be affected.

[0088] The part of the first inner frame strip 2A extending into the avoiding groove b is in contact with the inner wall of the avoiding groove b, that is, the first inner frame strip 2A is clamped into the second inner frame strip 2B, so that the relative stability of the arrangement of the first inner frame strip 2A and the second inner frame strip 2B can be ensured, and the stability of the overall structure of the carrier 01 can be ensured.

[0089] Through the above arrangement, when the plurality of inner frame strips 2 are arranged in a cross manner, the first inner frame strip 2A can be directly pressed into the avoiding groove b along the groove depth direction (perpendicular to the plane of the frame 1) of the avoiding groove b, so that the first inner frame strip 2A and the second inner frame strip 2B are arranged in a cross manner at the cross position. Such an arrangement not only facilitates the assembly of the first inner frame strip 2A and the second inner frame strip 2B, but also allows the groove depth of the avoiding groove b to be reasonably arranged, so that the upper end surfaces 21a of the first inner frame strip 2A and the second inner frame strip 2B are located in the same plane, thereby making the surface of the mesh structure composed of the plurality of inner frame strips 2 flat, facilitating the arrangement of the bearing protrusions 21, and facilitating the placement of the substrate 02.

[0090] It can be understood that, since the inner frame strip 2 is already connected to the frame 1, at the cross position, the first inner frame strip 2A and the second inner frame strip 2B can be not connected to each other. Of course, the first inner frame strip 2A and the second inner frame strip 2B can also be connected to each other. Several schemes for the mutual connection of the first inner frame strip 2A and the second inner frame strip 2B are provided below.

[0091] In some embodiments, as shown in Figure 10 , Figure 11 The carrier 01 further includes a crimping piece 4 arranged at the cross position. The crimping piece 4 includes a connecting portion 41 and a pressing portion 42. Along the arrangement direction of the first inner frame strip 2A and the second inner frame strip 2B, the connecting portion 41 passes through the first inner frame strip 2A and is connected to the second inner frame strip 2B, and the pressing portion 42 is connected to one end of the connecting portion 41 away from the second inner frame strip 2B and abuts against the first inner frame strip 2A. The pressing portion 42 avoids the bearing hole a.

[0092] It can be understood that a through hole is formed in the first inner frame strip 2A, and the connecting portion 41 passes through the first inner frame strip 2A through the through hole.

[0093] In some examples, when the limiting protrusion 31 is provided on the inner frame strip 2, the limiting protrusion 31 avoids the crimping piece 4, so that the installation and disassembly of the crimping piece 4 can be facilitated.

[0094] In some examples, the pressing portion 42 is a plate-shaped structure, and the side surface of the plate-shaped structure is in contact with the side surface of the first inner frame strip 2A. In this way, the abutting area can be increased, and the relative stability between the first inner frame strip 2A and the second inner frame strip 2B can be ensured.

[0095] The connection between the connection part 41 and the second inner frame strip 2B can be various.

[0096] For example, as shown in Figure 10 , Figure 11 , the connection part 41 includes a connecting column 411, a first bolt 412, and a first nut 413. The connecting column 411 passes through the first inner frame strip 2A and extends into the second inner frame strip 2B. A first through hole d is formed on the peripheral wall of the connecting column 411 in a direction perpendicular to the second inner frame strip 2B. A second through hole e is formed on the second inner frame strip 2B. After the connecting column 411 extends into the second inner frame strip 2B, the connecting column 411 extends into the second through hole e, and the first through hole d is located in the second through hole e. The first bolt 412 passes through the first through hole d and the second through hole e. Then, the first nut 413 is connected to the tail of the first bolt 412, thereby realizing the connection between the connection part 41 and the second inner frame strip 2B.

[0097] It should be noted that in this case, in order to facilitate the arrangement of the first bolt 412, the bottom surface of the first inner frame strip 2A is higher than the bottom surface of the second inner frame strip 2B. In this way, at the intersection position, the first inner frame strip 2A can avoid the first bolt 412 and will not affect the arrangement of the first bolt 412.

[0098] Alternatively, the connection part 41 can also directly include a screw, so that the screw directly extends into the second inner frame strip 2B to be connected with the second inner frame strip 2B in a threaded manner.

[0099] Through the above arrangement, the crimping piece 4 is connected to the first inner frame strip 2A and the second inner frame strip 2B through the connection part 41. Due to the presence of the pressing part 42, the pressing part 42 can press the first inner frame strip 2A against the second inner frame strip 2B. In this way, during the transportation of the carrier 01, the relative stability between the first inner frame strip 2A and the second inner frame strip 2B can be ensured, the vibration frequency between the first inner frame strip 2A and the second inner frame strip 2B is reduced, and the overall structural stability of the carrier 01 is ensured.

[0100] Of course, the first inner frame strip 2A and the second inner frame strip 2B can also be directly connected together through screws or other fasteners. Alternatively, they can be fixed together by gluing.

[0101] In some embodiments, as shown in Figure 10 , the side of the first inner frame strip 2A away from the second inner frame strip 2B has a receiving groove c, and the pressing part 42 is located in the receiving groove c.

[0102] In some examples, in the groove depth direction of the receiving groove c, the groove depth of the receiving groove c is consistent with the size of the pressing part 42. In this way, when the pressing part 42 is located in the receiving groove c, the surface of the first inner frame strip 2A can be ensured to be flat.

[0103] Of course, the depth of the accommodation groove c and the size of the crimping member 4 can also be inconsistent along the depth direction of the accommodation groove c.

[0104] In some examples, as shown in Figure 10 , Figure 11 the accommodation groove c extends through the first inner frame strip 2A along the extension direction of the second inner frame strip 2B. At this time, after the pressing part 42 is installed into the accommodation groove c, the pressing part 42 can be chamfered at the edge to avoid the bearing hole a, and in this case, the chamfered surface on the pressing part 42 can also bear the substrate 02.

[0105] By providing the accommodation groove c on the first inner frame strip 2A, the accommodation groove c can provide accommodation space for the pressing part 42, so that by reasonably setting the depth of the accommodation groove c, the upper surface of the pressing part 42 is close to or flush with the upper surface of the first inner frame strip 2A, so as to avoid the influence of the existence of the pressing part 42 on the surface flatness of the entire carrier 01.

[0106] In some embodiments, as shown in Figure 12 the end of the inner frame strip 2 is connected to the frame 1 through the first mortise and tenon structure 5. In this way, the connection between the inner frame strip 2 and the frame 1 is flat, and the connection method is also relatively simple and has high connection stability.

In this way, the connection between adjacent outer frame strips 11 is flat, and the connection method is also relatively simple and has high connection stability.
