Background

With the explosion of the semiconductor industry or the optoelectronic industry, more and more semiconductor devices or optoelectronic devices are required to be carried on a carrier for transporting the semiconductor devices or optoelectronic devices within a factory. Since the objects such as wafers, chips, masks or glass substrates are almost fragile objects in sheet form, they must be stable during transportation to prevent them from being cracked or damaged due to large shaking or collision. In particular, Integrated Circuit (IC) chips are typically placed in an array on trays (trays), and then the trays are placed in an IC Tray Cassette or magazine and transferred between stations in the factory. Since the chips are not usually held in the carrier, the transport system is inevitably shaken or vibrated during the transport of the carrier cassette or magazine. These jolts or vibrations may not have a significant effect on the carrier cassettes or magazines having a large mass, but for chips which are carried therein with a much smaller mass than the carrier cassettes or magazines, only slight jolts or vibrations may cause the individual chips to jump off or even fall off the place of placement and thus be damaged. Therefore, it is necessary to provide a buffer for the force generated by shaking or vibration during the transportation process to prevent the chip and other objects from being damaged.

On the other hand, since it is necessary to prevent dust from adhering to the wafer or mask during transportation, such as a wafer or a mask, which is susceptible to quality deterioration due to particle contamination, it is not possible to use a material that is likely to generate fine particles, such as paper or foam, as a cushion.

Detailed Description

Fig. 1 is a perspective view of a carrying device according to an embodiment of the present invention. Fig. 2 is a cross-sectional view of the carrier of fig. 1. Referring to fig. 1 and fig. 2, the carrier device 10 of the present embodiment includes a box 100, at least one clamping member 200, and a lifting member 300, and the carrier device 10 is adapted to accommodate at least one object 20.

In the drawings of 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 a plurality of the objects 20 are stacked on top of each other. The object 20 is a carrier, such as a wafer frame or a chip tray, or may be a wafer, a mask, a glass substrate or other fragile objects, which is not limited by the present invention.

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 sidewalls 110 of the box 100 each have a plurality of first grooves 111 for receiving the edge 21 of the object 20. The first grooves 111 on the two sidewalls 110 correspond to each other, and each of the first grooves 111 is disposed parallel to the bottom wall 130. That is, the edge 21 of the article 20 is adapted to extend into two corresponding first grooves 111 of the plurality of first grooves 111.

Each first groove 111 has a supporting portion 111 a. The supporting portion 111a is the upper surface of the bottom of the first groove 111 of the carrier 10 for accommodating the edge 21 of the object 20. When the article 20 is received in the carrier 10, the edge 21 of the article 20 is supported on the support 111 a.

The lifter 300 is movably disposed on the top wall 120 of the case 100. The number of the clamping members 200 is shown as two, but not limited thereto. The two clamping members 200 are movably disposed at the left and right sides of the box 100 and are connected to the lifting member 300 through a connecting rod 400.

Fig. 3 is a partially enlarged view of the carrier of fig. 2 with the article held by the clamp. Fig. 4 is an enlarged partial view of the carrier of fig. 2 with the holders thereof not holding an article.

Referring to fig. 3 and 4, the clamping member 200 moves between a first position shown in fig. 3 and a second position shown in fig. 4. When the clip 200 is in the first position as shown in fig. 3, the distance between the clip 200 and the support 111a of the first groove 111 is smaller than the distance between the clip 200 and the support 111a of the first groove 111 when the clip 200 is in the second position as shown in fig. 4.

Further, in the embodiment, when the lifting member 300 is lifted, the box 100 is retained at the original position by the gravity, and the box 100 will not be lifted by the lifting member 300 until the lifting member 300 reaches the top of the movable range above the box 100 and cannot move upward relative to the box 100.

At the stage when the lifting member 300 is lifted upwards and the box 100 is not lifted by the lifting member 300 due to gravity, the clamping member 200 is moved to the first position shown in fig. 3 by the lifting member 300, so that the edge 21 of the object 20 is clamped between the clamping member 200 and the supporting portion 111a of the first groove 111.

When the carrying operation is completed and the carrying device 10 is lowered to a placing position (not shown), the first gripping device of the carrying system is lowered continuously to lower the lifting member 300 to the bottom of its movable range and is not lifted any more. In this process, the clamp 200 is adapted to move to the second position shown in figure 4 to separate from the edge 21 of the article 20 as the lifting member 300 is lowered.

The material of the clamping member 200 can be selected from various materials, such as metal, plastic, or other materials, so long as it can stably grip the object 20 and has sufficient friction to prevent the object 20 from sliding. Of course, if the cleanliness of semiconductor or optoelectronic high-tech plants is considered, the material is better if it is resistant to abrasion and particle contamination.

In the above configuration, when the edge 21 of the article 20 is located in the first groove 111, the holding member 200 is driven along with the lifting member 300, so that the edge 21 of the article 20 is held between the holding member 200 and the supporting portion 111a of the first groove 111, thereby achieving the effect of positioning and stabilizing the article 20.

Therefore, the carrier 10 can fix the object 20 by the clamping member 200 and the supporting portion 111a of the first groove 111 during the carrying process, so as to absorb or reduce the external force applied to the carrier 10, thereby preventing the object 20 from generating excessive shaking or vibration in the carrier 10 and being impacted or falling off from the placing position.

As shown in fig. 1 and 2, the first groove 111 extends inside the sidewall 110 of the cartridge 100 along the first direction N1. The article 20 is adapted to enter and exit the receiving space a of the cartridge 100 in the first direction N1. The two clamping members 200 are adapted to move along a second direction N2 perpendicular to the first direction N1 to abut against the edge 21 of the object 20, wherein the second direction N2 is parallel to the side wall 110.

The sidewall 110 has at least one slot 112 corresponding to the two clamping members 200, one on each of the left and right sides in the exemplary embodiment. Each clamping member 200 is slidably disposed in the corresponding slot 112, and the two slots 112 and the two clamping members 200 are symmetrically disposed on two sides of the box 100. Thus, the two clamps 200 can be positioned evenly on both sides of the edge 21 of the article 20, symmetrically. In other embodiments, the slot 112 may be designed in other suitable forms, which is not limited by the present invention.

In detail, each of the clamping members 200 further has a plurality of second grooves 210. Each second groove 210 corresponds to a first groove 111 and also extends along the first direction N1, and the two edges 21 of the article 20 are adapted to extend into the two corresponding second grooves 210. Each of the second grooves 210 has a clamping portion 210 a. In this embodiment, the clamping portion 210a is a surface of the second groove 210 facing downward from the top.

When the clamping member 200 is located at the first position shown in fig. 3, the distance between the supporting portion 111a and the clamping portion 210a is smaller than that when the clamping member 200 is located at the second position shown in fig. 4. Based on this design, when the clamping member 200 is located at the first position shown in fig. 3, the edge 21 of the article 20 is clamped between the supporting portion 111a of the corresponding first groove 111 and the clamping portion 210a of the second groove 210.

When the clamping member 200 is located at the second position shown in fig. 4, the distance between the supporting portion 111a and the clamping portion 210a is greater than the distance between the supporting portion 111a and the clamping portion 210a when the clamping member 200 is located at the first position shown in fig. 3. The edge 21 of the article 20 can pass through the first groove 111 and the second groove 210 to be accessed. When the object 20 is put into the carrier 10, the edge 21 is supported on the supporting portion 111a of the first groove 111 and separated from the clamping portion 210a of the second groove 210.

It should be noted that when no article 20 is received in the carrier 10, the range of up and down movement of the clamp 200 may be greater than or equal to the thickness of the edge 21 of the article 20. However, when the first and second grooves 111 and 210 contain the object 20, the distance that the holding member 200 moves from the first position shown in fig. 3 to the second position shown in fig. 4 is just equal to the thickness of the edge 21 of the object 20.

When the clamping member 200 is located at the second position, the bottom edge of the second groove 210 is not higher than the bottom edge of the corresponding first groove 111, i.e. the bottom edge of the second groove 210 is located at the same height as or slightly lower than the bottom edge of the corresponding first groove 111 (fig. 4 shows an embodiment in which the bottom edge of the second groove 210 is slightly lower than the bottom edge of the corresponding first groove 111). So that the edge 21 of the object 20 can pass through the first groove 111 and the second groove 210 smoothly during the process of being taken and placed.

In addition, the number of the second grooves 210 of the present embodiment is the same as the number of the first grooves 111. Of course, in other embodiments, the form and number of the first grooves 111 and the second grooves 210 may be determined according to the requirement, and the invention is not limited thereto.

The way in which the lifting member 300 of the present embodiment drives the clamping member 200 is described in detail below. The carrier 10 includes at least one link 400. In the present embodiment, the number of the links 400 is shown as two, but not limited thereto, and the two links 400 are disposed on the top wall 120 of the case 100.

In detail, each link 400 has a first abutting portion 410, a second abutting portion 420 and a pivot portion 430. The first abutting portion 410 rotatably abuts against the lifting member 300, the second abutting portion 420 is pivotally connected to the corresponding clamping member 200, and the pivotally connected portion 430 is pivotally connected to the top wall 120 of the box 100 and located between the first abutting portion 410 and the second abutting portion 420.

It should be noted that, in an embodiment not shown, the first abutting portion 410 can also be pivoted to the lifting member 300, the second abutting portion 420 can also be rotatably abutted against the corresponding clamping member 200, and the clamping member 200 can be further connected with a reset element, such as a reset spring (not shown), so that the clamping member 200 can be reset to the second position shown in fig. 4 when not being abutted by the second abutting portion 420 of the connecting rod 400, which is not limited by the present invention.

Referring to fig. 3 and 4, the lifting member 300 further has at least one groove 320. In the present embodiment, the number of the grooves 320 is one on the left and right, but not limited thereto. The first abutment 410 of the link 400 is rotatably abutted against the recess 320 of the lift 300 about a first rotational axis a 1.

In detail, the first rotation axis a1 is parallel to a second rotation axis a2 of the second abutting portion 420 and a pivot axis A3 of the pivot portion 430, and the first rotation axis a1 is parallel to the first direction N1 and perpendicular to the second direction N2, so that the lifting element 300 can smoothly drive the clamping element 200 to move along the second direction N2 perpendicular to the first direction N1.

In other words, when the lifting element 300 is lifted, the lifting element 300 drives the link 400 to rotate relative to the case 100 with the pivot 430 as a rotation center, and the link 400 drives the clamping element 200 to slide down along the second direction N2 and abut against the edge 21 of the object 20, so that the edge 21 of the object 20 is clamped between the supporting portion 111a of the corresponding first groove 111 and the clamping portion 210a of the corresponding second groove 210 to be positioned.

On the other hand, the box 100 has at least one sliding column 140, and a stopping portion 142 is disposed at a top end of each sliding column 140. The lifting member 300 further has a sliding portion 340, and the sliding portion 340 of the lifting member 300 has at least one sliding hole 340a corresponding to the sliding column 140 of the box 100.

The lifting member 300 is slidably disposed on the corresponding sliding column 140 of the box 100 through the sliding hole 340a of the sliding portion 340, and the sliding range of the sliding portion 340 of the lifting member 300 is limited between the box 100 and the stopping portion 142.

To sum up, the utility model discloses an among the carrying device, set up movable lifting piece and be connected and can with the clamping piece of lifting piece interlock at the box body, so when the edge of the article that is born is located first slot and second slot, the clamping piece can be driven along with the rising of lifting piece, makes between the supporting part of the edge of article by the first slot of centre gripping on the lateral wall and the clamping part of the second slot on the clamping piece to reach the effect of fixed article. Therefore, in the carrying and conveying process of the carrying device, the object can be clamped and fixed by the clamping part of the clamping piece and the supporting part of the first groove together, so that the influence of external force such as shaking and vibration and the like on the carried object of the carrying device is reduced, and the object is prevented from being impacted, falling off from a placing position and being damaged due to excessive shaking or vibration in the carrying device.
