Description

Carrying device

Technical Field

The present invention relates to a carrying device, and more particularly to a carrying device for carrying a sheet-like article requiring high stability.

Background

With the rapid development of the semiconductor industry and the optoelectronic industry, more and more carriers designed specifically for the related industry needs are being used in large quantities to transport semiconductor devices or optoelectronic devices in a factory. Since the wafer, the mask, the glass substrate or the chip are usually fragile objects, they must be kept stable during the transportation process to avoid the fragile objects from being damaged or cracked by excessive shaking, vibration or impact. In particular, Integrated Circuit (IC) chips are typically placed in an array on trays (trays), and then the trays are loaded into an IC Tray Cassette or a magazine (Magazine) for transport between stations in a factory floor. Since the chips are not fixed when they are placed on the tray, and the ic tray cassette generally does not provide any fixing or buffering to the tray, when the ic tray cassette is subjected to external forces such as vibration or impact during transportation and transmission and transmits the external forces to the chips, the objects having a mass much smaller than that of the ic tray cassette may be excessively shaken or vibrated, and in severe cases, may even jump off the place and fall off and be damaged.

In addition, since articles such as substrates and devices used in these industries and the environment in the factory must be protected from being contaminated with particles to affect the quality, materials such as foam, which are prone to generate fine particles or particles, cannot be used as a buffer.

Referring to fig. 1 and 2, the carrier device 10 of the present embodiment includes a box 100, and the box 100 is adapted to accommodate the object 20.

In the present embodiment, the number of the objects 20 is shown as one, but in other embodiments, the number of the objects 20 may be multiple, and the multiple objects 20 are stacked at intervals. In addition, the object 20 is illustrated as a rectangular substrate in the present embodiment, but in other embodiments, the object 20 may be a tray for placing integrated circuit chips, or a sheet-like or plate-like object such as a wafer or a mask. The utility model discloses do not restrict this.

The box 100 includes a top wall 120, two sidewalls 110 connected to the top wall 120 and opposite to each other, and a bottom wall 130 connected to the two sidewalls 110 and opposite to the top wall 120. The top wall 120, the two sidewalls 110 and the bottom wall 130 together define a receiving space a for receiving the object 20.

The two side walls 110 of the box 100 are respectively provided with a plurality of grooves 111 arranged parallel to the bottom wall 130, and the plurality of grooves 111 on the two side walls 110 correspond to each other. The edge 21 of the article 20 is adapted to extend into two corresponding grooves 111 of the plurality of grooves 111 on the two sidewalls 110.

Fig. 3 is an enlarged view of a portion of the carrier of fig. 2. Referring to fig. 3, the carrying device 10 of the present embodiment further includes a plurality of elastic members 200. The material of the elastic member 200 can be selected from many different materials, such as metal, plastic, or other materials with elasticity, which is not limited by the present invention.

Each elastic member 200 is disposed or formed in the plurality of grooves 111, and adapted to abut against the upper surface of the article 20 adjacent to the edge 21, and press and hold the article 20 by an elastic force generated by the elastic deformation, so that the article 20 is held in place.

Meanwhile, since the elastic member 200 is disposed in the groove 111 of the box 100, when the edge 21 of the carried object 20 is located in the groove 111, the object 20 can be buffered by the elastic member 200 during the carrying process to absorb or reduce the external force applied to the carrying device 10, thereby preventing the object 20 from shaking, vibrating or jumping in the carrying device 10.

As shown in fig. 1 and 2, each of the grooves 111 extends along a first direction N1, and the articles 20 are adapted to enter the accommodating space a of the box 100 along the first direction N1. And elastic member 200 is adapted to elastically deform and press against article 20 adjacent edge 21 in a second direction N2 perpendicular to first direction N1. Wherein the second direction N2 is perpendicular to the bottom wall 130.

Each side wall 110 may be integrally formed, or as exemplified in fig. 1-3: each side wall 110 includes a wall portion 112 and two positioning portions 113. The wall portion 112 of each sidewall 110 has two slots 112a, and each positioning portion 113 is combined in one slot 112 a.

In this embodiment, each of the grooves 111 includes at least one first groove 111a formed in the wall portion 112 and at least one second groove 111c formed in the positioning portion 113. The elastic member 200 is disposed or formed in each second groove 111c of each positioning portion 113.

As shown in fig. 3, in order to make the edge 21 of the article 20 smoothly move along the groove 111 when the article 20 is placed in or removed from the carrier 10, the upper edge of each second groove 111c must not be lower than the upper edge of the corresponding first groove 111a, and the lower edge of each second groove 111c must not be higher than the lower edge of the corresponding first groove 111 a.

The elastic member 200 and the positioning portion 113 may be respectively manufactured and then the elastic member 200 is disposed on the positioning portion 113, or the elastic member 200 and the positioning portion 113 may be integrally formed such that each elastic member 200 is protruded in the accommodating space a. The combination of the positioning portion 113 and the slot 112a may be a snap, a buckle, an adhesive, or any other suitable manner, which is not limited in this embodiment.

In other embodiments, each sidewall 110 may also have one or more than two positioning portions 113. The number of the positioning portions 113 may be determined according to different requirements such as the size of the object 20 and the stability requirement. When each sidewall 110 has two or more positioning portions 113, the positioning portions 113 are arranged along the direction in which the groove 111 extends, and the positioning portions 113 in each row are aligned with each other.

In addition, the slots 112a in the present embodiment are provided as examples of symmetry, so that the positioning portions 113 can be positioned at two positions on the edge 21 of the article 20 more evenly. In other embodiments, the slot 112a may be designed in other suitable forms, which is not limited by the present invention.

Each first groove 111a has a first inner surface 111 b. The first inner surface 111b is an upward surface of the first groove 111a and is adapted to abut against a lower surface of the article 20 adjacent to the edge 21 to support the article 20. Each second groove 111c has a second inner surface 111 d. The second inner surface 111d is a surface of the second groove 111c facing downward.

The elastic member 200 is connected to the second inner surface 111d and extends downward. After the edge 21 of the object 20 extends into the first groove 111a and the second groove 111c, each elastic member 200 abuts against the upper surface of the object 20 adjacent to the edge 21. Each elastic member 200 is also pushed by the object 20 to be elastically deformed upwards, and thus generates a downward elastic force, so that the object 20 can be positioned and held inside the box 100.

In detail, when the edge 21 of the object 20 does not enter the first groove 111a and the second groove 111c and the elastic member 200 is not pushed by the object 20 and elastically deformed, a distance D is formed between the lower edge of the first groove 111a and the elastic member 200, and the thickness W at the edge 21 of the object 20 is greater than the distance D.

When the edge 21 of the object 20 extends into the first groove 111a and the second groove 111c, since the original distance D between the lower edge of the first groove 111a and the elastic member 200 is smaller than the thickness W of the edge 21 of the object 20, the elastic member 200 is pushed by the object 20 to be elastically deformed upward, and a downward returning elastic force is generated to press and hold the object 20.

When the carrying device 10 shakes or vibrates due to some reasons during carrying the object 20, the elastic member 200 can absorb an external force through elastic deformation to exert a buffering effect, thereby preventing the object 20 from shaking or vibrating excessively.

Particularly, when the carrier tray is used for carrying the ic chip, the buffering effect of the elastic member 200 can prevent the shaking or vibration force from being transmitted to the carrier tray, and then the vibration force is transmitted from the carrier tray to the chip carried thereon, so that the chip is damaged due to excessive vibration, or the chip is dropped from the carrier position due to excessive vibration, thereby causing damage.

The elastic members 200 can have many different structural designs, and each elastic member 200 in the present embodiment is a curved shape having two first bending portions 210 and a second bending portion 220 between the two first bending portions 210, and has a wavy shape.

The two first curved portions 210 project away from the second inner surface 111d and are adapted to abut the upper surface of the article 20 adjacent to the edge 21. The second curved portion 220 is disposed between the two first curved portions 210, and the second curved portion 220 protrudes toward the second inner surface 111 d.

Such a structure allows each elastic member 200 to increase the range of holding the object 20 by the plurality of first bending portions 210, thereby providing a better fixing effect. But does not need to increase the area in contact with the article 20 so much as to avoid dust generated by friction between the two as the article 20 slides through. In other embodiments, the elastic member 200 may be designed in other suitable forms, and the invention is not limited thereto.

In addition, a gap T is provided between the second curved portion 220 and the second inner surface 111 d. The width of the gap T must be greater than the distance that the elastic member 200 is elastically deformed upwards by the pushing of the object 20, so that when the object 20 is placed in the box 100, there is enough space for the elastic member 200 to elastically deform upwards to allow the edge 21 of the object 20 to pass between the first bending portion 210 and the first inner surface 111 b.

In a preferred embodiment, the second inner surface 111d has a recess U for receiving the second bending portion 220 of the elastic member 200. Since the surface of the recess U is also a part of the second inner surface 111d, the surface of the recess U also has the gap T as in the second curved portion 220.

When the object 20 is placed in the box 100, the elastic member 200 is pushed by the object 20 to be elastically deformed upwards, and the second bending portion 220 can move towards the recess U. When the elastic member 200 is elastically deformed, at least a portion of the second bent portion 220 protrudes into the corresponding recess U.

When the carrier 10 is vibrated or bounced by external forces, the forces are also transmitted to the object 20 through the first inner surface 111b of the object 20. At this time, the elastic force of the elastic member 200 must be applied to press the object 20. In addition, the elastic member 200 can provide a buffering effect by utilizing the elastic deformation capability.

In an alternative embodiment, the carrier 10 may not have slots and detents. At this time, each of the trenches 111 is no longer divided into a first trench and a second trench, the first inner surface 111b is the lower surface of the trench 111, and the second inner surface 111d is the upper surface of the trench 111. In addition, the function and the operation mechanism for holding the object 20 are the same as those described above, and therefore, the detailed description thereof is omitted.

To sum up, in the carrying device of the present invention, the elastic member is disposed in the groove of the box body, so that when the edge of the loaded article is located in the groove, the edge of the article can abut against the elastic member and receive the elastic member to fix the article by elastic force. Meanwhile, the carrying device can utilize the buffering provided by the elastic piece to absorb or reduce the external force effect transmitted to the object carried in the carrying device in the carrying process, so that the object is prevented from being impacted, falling off from the placing position and even damaged due to excessive shaking or vibration in the carrying device.
