Description

Technical Field

[0001] The present invention relates to the technical field of storage devices, and particularly to a storage device for preventing circuit boards from sagging. Background Art

[0002] Generally speaking, traditional storage devices can be used to accommodate printed circuit boards. The storage device can push the printed circuit board out of the device, and another transfer mechanism can transfer the printed circuit board from the storage device to a circuit board drilling machine for subsequent drilling processes of the circuit board.

[0003] However, as the size of the printed circuit board gradually increases, the weight of the printed circuit board also increases. When the printed circuit board is pushed out of the storage device, due to the overweight printed circuit board, the end of the shelf carrying the printed circuit board will float in the air and tilt, resulting in the corresponding tilt of the circuit board surface. This makes the adsorption force uneven at various places when the transfer mechanism transfers the printed circuit board, causing the printed circuit board to easily fall during the transfer process and damage the printed circuit board. Summary of the Invention

[0004] The purpose of the present invention is to provide a storage device for preventing circuit boards from sagging. The first bearing part of the first storage shelf pushed outwards remains parallel to the horizontal direction after leaving the flat part of the mobile carriage, which can prevent the printed circuit board arranged on the first bearing part of the first storage shelf from tilting relative to the horizontal direction.

This storage device for preventing circuit boards from sagging includes a mobile carriage, a first storage shelf, and a laterally extending jig; the mobile carriage has a carriage part and a flat part arranged on the carriage part; the flat part has a first slide rail arranged along the horizontal direction; the first storage shelf is movably arranged on the flat part of the mobile carriage and has a first slide part and a first bearing part connecting the first slide part; the first slide part of the first storage shelf is used to move along the horizontal direction in the first slide rail of the flat part of the mobile carriage to drive the first bearing part of the first storage shelf to move along the horizontal direction simultaneously, and the first bearing part is used to carry the printed circuit board; the laterally extending jig is arranged on one side of the mobile carriage and has an extending horizontal part and an extending vertical part connecting the extending horizontal part; the extending horizontal part of the laterally extending jig is connected to the bearing end of the first bearing part of the first storage shelf far from the first slide part, and when the first storage shelf is driven to be pushed outwards along the horizontal direction from the mobile carriage, the laterally extending jig is driven by the first storage shelf to move along the horizontal direction, so that the first bearing part of the first storage shelf pushed outwards remains parallel to the horizontal direction after leaving the flat part of the mobile carriage, to prevent the printed circuit board arranged on the first bearing part from tilting relative to the horizontal direction.

[0006] According to an embodiment of the present disclosure, one end of the extending vertical portion of the above-mentioned horizontally extending jig is connected to the extending horizontal portion, and the other end of the extending vertical portion of the horizontally extending jig has an extending auxiliary wheel. When the horizontally extending jig is driven by the first storage layer rack to move in the horizontal direction, the extending auxiliary wheel is used to assist the horizontally extending jig to move in the horizontal direction.

[0007] According to an embodiment of the present disclosure, when the first bearing portion of the first storage layer rack is pushed outwards from the moving vehicle platform, the extending horizontal portion, the extending vertical portion and the extending auxiliary wheel of the horizontally extending jig are used to support the bearing end of the first bearing portion in the vertical direction perpendicular to the horizontal direction, so that the first bearing portion of the first storage layer rack remains parallel to the horizontal direction.

[0008] According to an embodiment of the present disclosure, the above-mentioned circuit board anti-vertical storage device further includes a first power driving mechanism; the first power driving mechanism is arranged on the flat portion of the moving vehicle platform and is connected to the first sliding table portion of the first storage layer rack. The first power driving mechanism is used to push the printed circuit board arranged on the first bearing portion out of the flat portion, or pull the printed circuit board back above the flat portion from outside the moving vehicle platform.

[0009] According to an embodiment of the present disclosure, the above-mentioned first storage layer rack has a plurality of auxiliary fixing columns, and the plurality of auxiliary fixing columns of the first storage layer rack are used to move on the first bearing portion to abut against the periphery of the printed circuit board.

[0010] According to an embodiment of the present disclosure, the plurality of auxiliary fixing columns of the first storage layer rack are located between the first sliding table portion of the first storage layer rack and the horizontally extending jig to stabilize the printed circuit board on the first bearing portion of the first storage layer rack.

[0011] According to an embodiment of the present disclosure, the above-mentioned circuit board anti-vertical storage device further includes a second storage layer rack and a second power driving mechanism. The second storage layer rack is movably arranged above the flat portion of the moving vehicle platform, and the second storage layer rack is used to be pushed outwards from the moving vehicle platform in the horizontal direction. The second power driving mechanism is arranged on one side of the second storage layer rack and is connected to the second storage layer rack. The second power driving mechanism is used to push the circuit board partition arranged on the second storage layer rack out of the moving vehicle platform, or pull the circuit board partition arranged on the second storage layer rack back above the flat portion from outside the moving vehicle platform.

[0012] According to an embodiment of the present disclosure, the above-mentioned circuit board anti-vertical storage device further includes a robotic arm; the robotic arm is arranged above the flat portion of the moving vehicle platform; after the first storage layer rack is pushed outwards from the moving vehicle platform in the horizontal direction, the robotic arm is used to transfer the printed circuit board arranged on the first bearing portion of the first storage layer rack to the circuit board drilling machine.

Detailed implementation manners

[0025] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0026] Please refer to Figures 1 to 3 , Figure 1 Shows a perspective view of the circuit board anti - sag storage device 100 according to an embodiment of the present disclosure. Figure 2 Shows Figure 1 A perspective view of the circuit board anti - sag storage device 100 from another perspective, and Figure 3 Shows a perspective view of the first storage rack 120 of the circuit board anti - sag storage device 100 being pushed outwards according to an embodiment of the present disclosure. As the size of the printed circuit board 200 gradually increases, thereby increasing the weight of the printed circuit board 200, the mechanism for carrying the printed circuit board 200 must be changed. In Figures 1 to 3In it, the circuit board anti - sag storage device 100 includes a mobile vehicle platform 110, a first storage layer rack 120, and a laterally extending jig 130; the mobile vehicle platform 110 has a vehicle platform part 112 and a flat plate part 114 disposed on the vehicle platform part 112; for example, the vehicle platform part 112 of the mobile vehicle platform 110 can be moved to a desired position according to an instruction, for example, the mobile vehicle platform 110 can be an unmanned vehicle carrier; the flat plate part 114 of the mobile vehicle platform 110 has a first slide rail 116; the first storage layer rack 120 is movably disposed on the flat plate part 114 of the mobile vehicle platform 110; the first storage layer rack 120 has a first slide table part 122 and a first bearing part 124 connecting the first slide table part 122; the first bearing part 124 of the first storage layer rack 120 is used to carry the printed circuit board 200, as Figure 3 shown.

[0027] In some embodiments, the laterally extending jig 130 is disposed on one side of the mobile vehicle platform 110, and the laterally extending jig 130 has an extending horizontal part 132 and an extending vertical part 134 connecting the extending horizontal part 132. The extending horizontal part 132 of the laterally extending jig 130 is connected to the bearing end 126 of the first bearing part 124 of the first storage layer rack 120 away from the first slide table part 122. Specifically, the first end of the first bearing part 124 of the first storage layer rack 120 is the first slide table part 122, and the second end of the first bearing part 124 of the first storage layer rack 120 relative to the first end is the bearing end 126. Since the laterally extending jig 130 supports the bearing end 126 of the first storage layer rack 120, the distances from the opposite ends (i.e., the first end and the second end) of the first bearing part 124 of the first storage layer rack 120 to the ground are the same, that is, the first bearing part 124 of the first storage layer rack 120 is parallel to the horizontal direction D1 (which will be Figure 4 described in detail).

[0028] Please refer to Figure 4 and Figure 5 , Figure 4 and Figure 5 which show side views of the first storage layer rack 120 of the circuit board anti - sag storage device 100 according to some embodiments of the present disclosure when being respectively pushed outwards and pulled inwards. In Figures 1 to 5In this case, the first slide rail 116 of the mobile vehicle platform 110 is arranged along the horizontal direction D1, and the first slide table part 122 of the first storage layer rack 120 is arranged in the first slide rail 116 of the mobile vehicle platform 110. Moreover, the first slide table part 122 of the first storage layer rack 120 is used to move along the horizontal direction D1 in the first slide rail 116 of the flat part 114 of the mobile vehicle platform 110, so as to drive the first bearing part 124 of the first storage layer rack 120 to move along the horizontal direction D1 simultaneously. It should be noted that when the first storage layer rack 120 of the circuit board anti - sag storage device 100 is driven to be pushed outwards from the mobile vehicle platform 110 along the horizontal direction D1, the lateral extension jig 130 is driven by the first storage layer rack 120 to move along the horizontal direction D1. As a result, the first bearing part 124 of the first storage layer rack 120 pushed outwards remains parallel to the horizontal direction D1 after moving away from the flat part 114 of the mobile vehicle platform 110, so as to prevent the printed circuit board 200 arranged on the first bearing part 124 from tilting relative to the horizontal direction D1 (that is, due to the overweight of the printed circuit board 200 and the gravitational force, the first bearing part 124 carrying the printed circuit board 200 tilts downwards in the other direction of the vertical direction D2).

[0029] Specifically, when the first storage layer rack 120 of the circuit board anti - sag storage device 100 is driven to be pushed outwards from the mobile vehicle platform 110 along the horizontal direction D1, the lateral extension jig 130 is simultaneously driven by the first storage layer rack 120 to move along the horizontal direction D1. As a result, the first bearing part 124 of the first storage layer rack 120 pushed outwards remains parallel to the horizontal direction D1 after moving away from the flat part 114 of the mobile vehicle platform 110, which can prevent the printed circuit board 200 arranged on the first bearing part 124 of the first storage layer rack 120 from tilting relative to the horizontal direction D1. That is to say, even if the size of the printed circuit board 200 gradually increases and the weight of the printed circuit board 200 increases, the bearing end 126 of the first bearing part 124 of the first storage layer rack 120 carrying the printed circuit board 200 can be supported by the lateral extension jig 130, so that the bearing end 126 of the first bearing part 124 does not tilt. Furthermore, the printed circuit board 200 maintaining the horizontal direction D1 can have a uniform adsorption force during subsequent transfer, and the situation that the printed circuit board 200 is easily dropped and damaged during the transfer process due to uneven adsorption force can be avoided.

[0030] In some embodiments, one end of the extension vertical portion 134 of the horizontally extending jig 130 is connected to the extension horizontal portion 132, and the other end of the extension vertical portion 134 of the horizontally extending jig 130 has an extension auxiliary wheel 136. When the horizontally extending jig 130 is driven by the first storage layer rack 120 to move in the horizontal direction D1, the extension auxiliary wheel 136 is used to assist the horizontally extending jig 130 to move in the horizontal direction D1. In addition, when the first bearing portion 124 of the first storage layer rack 120 is pushed outwards from the mobile platform 110, the extension horizontal portion 132, the extension vertical portion 134 and the extension auxiliary wheel 136 of the horizontally extending jig 130 are used to support the bearing end 126 of the first bearing portion 124 in the vertical direction D2 perpendicular to the horizontal direction D1, so that the first bearing portion 124 of the first storage layer rack 120 remains parallel to the horizontal direction D1.

[0031] Please refer to Figures 4 to 6 , Figure 6 the perspective view when the second storage layer rack 150 of the circuit board anti-vertical storage device 100 according to an embodiment of the present disclosure is pushed outwards. In Figures 4 to 6 , the circuit board anti-vertical storage device 100 further includes a first power driving mechanism 140, a second storage layer rack 150 and a second power driving mechanism 170. The first power driving mechanism 140 is disposed on the flat portion 114 of the mobile platform 110, and the first power driving mechanism 140 is connected to the first sliding table portion 122 of the first storage layer rack 120. The first power driving mechanism 140 is used to push the printed circuit board 200 disposed on the first bearing portion 124 out of the flat portion 114 of the mobile platform 110, or pull the printed circuit board 200 back above the flat portion 114 from outside the mobile platform 110. In addition, the second storage layer rack 150 is movably disposed above the flat portion 114 of the mobile platform 110, and the second storage layer rack 150 is used to be pushed outwards from the mobile platform 110 in the horizontal direction D1. The function of the second storage layer rack 150 is the same as that of the first storage layer rack 120, both of which are used to push the carried object out of the mobile platform 110, or pull the carried object back above the flat portion 114 from outside the mobile platform 110. The second power driving mechanism 170 is disposed on one side of the second storage layer rack 150 and connected to the second storage layer rack 150. The second power driving mechanism 170 is used to push the circuit board partition 400 disposed on the second storage layer rack 150 out of the mobile platform 110, or pull the circuit board partition 400 disposed on the second storage layer rack 150 back above the flat portion 114 from outside the mobile platform 110. Specifically, since the weight of the circuit board partition 400 is much smaller than that of the printed circuit board 200, the second storage layer rack 150 will not tilt due to its own weight when the circuit board partition 400 is pushed out of the mobile platform 110. The structure of the multi-layer storage rack can improve the applicability of the circuit board anti-vertical storage device 100.

[0032] In some embodiments, the first storage rack 120 has a plurality of auxiliary fixing columns 128. For example, the first storage rack 120 has four auxiliary fixing columns 128, and these four auxiliary fixing columns 128 of the first storage rack 120 are used to move on the first bearing portion 124 to abut against the periphery of the printed circuit board 200. On the other hand, these four auxiliary fixing columns 128 of the first storage rack 120 are located between the first sliding table portion 122 of the first storage rack 120 and the laterally extending jig 130 to firmly fix the printed circuit board 200 on the first bearing portion 124 of the first storage rack 120.

[0033] Please refer to Figure 7 and to Figure 9 , Figure 7 and Figure 8 FIG. shows a side view of the operation of the robotic arm 160 of the circuit board anti - sag storage device 100a according to some other embodiments of the present disclosure. Figure 9 FIG. shows a schematic diagram of the transfer of the printed circuit board 200 in the circuit board anti - sag storage device 100a according to another embodiment of the present disclosure. In Figures 7 to 9 the figure, Figure 7 the circuit board anti - sag storage device 100a shown and Figure 4 the circuit board anti - sag storage device 100 shown are different in that the circuit board anti - sag storage device 100a further includes a robotic arm 160. The robotic arm 160 of the circuit board anti - sag storage device 100a is disposed above the flat portion 114 of the mobile carriage 110. Specifically, after the first storage rack 120 is pushed outwards from the mobile carriage 110 in the horizontal direction D1, the robotic arm 160 of the circuit board anti - sag storage device 100a is used to transfer the printed circuit board 200 disposed on the first bearing portion 124 of the first storage rack 120 to the circuit board drilling machine 300. In addition, after the printed circuit board 200 is transferred to the circuit board drilling machine 300, the second power driving mechanism 170 can then push the circuit board partition 400 disposed on the second storage rack 150 out of the mobile carriage 110, so as to transfer the circuit board partition 400 to the printed circuit board 200 located on the circuit board drilling machine 300 by means of the robotic arm 160 to protect the printed circuit board 200 during the drilling process. The circuit board partition 400, whose weight is much less than that of the printed circuit board 200, will not cause the second storage rack 150 to tilt due to its own weight. Therefore, the second storage rack 150 does not require a design of end support, enabling the circuit board anti - sag storage device 100 to be provided with a design of multiple storage racks, thereby improving the applicability of the circuit board anti - sag storage device 100.

[0034] In some embodiments, the robotic arm 160 has a plurality of vacuum suction members 162, and these vacuum suction members 162 are arranged along the horizontal direction D1; after the first storage rack 120 is pushed outwards from the mobile carriage 110 along the horizontal direction D1 and the printed circuit board 200 is kept parallel to the horizontal direction D1, a plurality of vacuum suction members 162 located above and on opposite sides of the printed circuit board 200 are used to adsorb the circuit board surface 210 of the printed circuit board 200; specifically, even if the size of the printed circuit board 200 gradually increases and the weight of the printed circuit board 200 increases, the bearing end 126 of the first bearing portion 124 of the first storage rack 120 carrying the printed circuit board 200 can be supported by the laterally extending jig 130, so that the bearing end 126 of the first bearing portion 124 does not tilt, and further, the printed circuit board 200 kept in the horizontal direction D1 can evenly adsorb the circuit board surface 210 of the printed circuit board 200 when adsorbed by the vacuum suction members 162, and the situation that the printed circuit board 200 is easily dropped and damaged due to uneven adsorption force during the transfer process can be avoided.

[0035] The above disclosure is only one or more preferred embodiments of the present application, and the scope of the rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
