[0001] The utility model relates to the manufacturing field of a mask plate transport box, and in particular designs a crane plate connecting mechanism which is beneficial to improving the sealing performance of the mask plate transport box. Background Art

[0002] The mask plate transport box is a packaging box specially designed to protect the mask plate during transportation. When the overhead crane takes and places the mask plate transport box, the overhead crane grabs the overhead crane plate of the mask plate transport box to complete the taking and placing action each time. Therefore, in order to ensure the stability of the connection, the mask plate transport box and the overhead crane plate on the market are mostly directly locked together by screws between the overhead crane plate and the upper cover of the mask plate transport box. Therefore, it is necessary to open screw holes on the upper cover of the mask plate transport box, so impurities such as dust and metal ions can easily enter the interior of the mask plate transport box through the screw holes, causing pollution to the mask plate. Summary of the invention

[0008] Furthermore, the connecting member mounting frame is fixedly arranged on a side of the overhead travelling carriage facing the mask plate transport box, and is a square frame body matching the length and width occupied by the first connecting unit.

[0009] Furthermore, the two first clamping bodies are arranged opposite to each other, that is, the opening directions of the two first clamping grooves are opposite to each other and face one side of the top edge of the mask plate transport box.

[0016] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the present invention herein is not intended to limit the protection scope of the present invention.

[0017] like Figures 1 to 3As shown, it is a schematic diagram of the structure of a crane plate connection mechanism provided by the utility model that is conducive to improving the sealing of a mask plate transport box. The crane plate that is conducive to improving the mask plate transport box includes a mask plate transport box 1, a crane plate 2 fixedly connected to the mask plate transport box 1, and a connection mechanism 10 disposed between the mask plate transport box 1 and the crane plate 2 for connecting the mask plate transport box 1 and the crane plate 2. It is conceivable that the crane plate connection mechanism that is conducive to improving the sealing of the mask plate transport box should also include some other functional components, such as assembly components, fastening components, etc., which are prior arts known to those skilled in the art and will not be elaborated on here.

[0018] The mask plate transport box 1 is used to accommodate, protect and transport the mask plate. One side of the overhead crane plate 2 is fixedly connected to the mask plate transport box 1, and the other side is fixedly connected to the overhead crane transport system, so as to realize the automatic transportation of the mask plate transport box 1. The mask plate transport box 1 and the overhead crane plate 2 are both prior arts known to those skilled in the art, and will not be described in detail here.

[0019] The connecting mechanism 10 includes a first connecting unit 11 fixedly disposed on the top of the mask plate transport box 1, and a second connecting unit 12 fixedly disposed on a side where the overhead traveling plate 2 is connected to the mask plate transport box 1.

[0020] The first connection unit 11 includes two position-limiting clamping sliders 111 symmetrically arranged on the top of the mask plate transport box 1, and two guide clamping sliders 112 symmetrically arranged on one side of the position-limiting clamping sliders 111. The extension direction of the two position-limiting clamping sliders 111 coincides with the extension direction of the two guide clamping sliders 112, that is, any one of the guide clamping sliders 112 is arranged in a straight line with one of the position-limiting clamping sliders 111.

[0021] Each of the position-limiting clamping sliders 111 includes a first clamping body 1111, a first clamping groove 1112 disposed on one side of the first clamping body 1111, and a first position-limiting protrusion 1113 fixedly disposed on the top wall of the first clamping body 1111. The outer contour of the first clamping body 1111 is an inverted L-shaped configuration. One side of the first clamping body 1111 is fixedly connected to the top of the mask plate transport box 1, and the other side of the first clamping body 1111 is parallel to the top of the mask plate transport box 1 and forms the first clamping groove 1112. The two first clamping bodies 1111 are disposed opposite to each other, that is, the opening directions of the two first clamping grooves 1112 are opposite to each other, and the opening directions are both oriented toward one side of the top edge of the mask plate transport box 1. The first position-limiting protrusion 1113 can be a cylindrical protrusion, and is fixedly disposed at one end of the first clamping body 1111 close to the top edge of the mask plate transport box 1.

[0022] Each of the guide clamping sliders 112 includes a second clamping body 1121 and a second clamping groove 1122 arranged on one side of the second clamping body 1121. The outer contour of the second clamping body 1121 is also an inverted L-shaped structure. One side of the second clamping body 1121 is fixedly connected to the top of the mask plate transport box 1, and the other side of the second clamping body 1121 is parallel to the top of the mask plate transport box 1 to form the second clamping groove 1122. The opening directions of the two second clamping grooves 1122 are also arranged opposite to each other and both face one side of the top edge of the mask plate transport box 1. That is, the opening directions of the first clamping groove 1112 and the second clamping groove 1122 located on the same side are consistent. The limiting clamping slider 111 and the guide clamping slider 112 are both used to cooperate with the second connection unit 12 to connect the mask plate transport box 1 with the overhead traveling crane 2. Therefore, it will be described in detail below in conjunction with the second connection unit 12 and will not be repeated here.

[0023] The second connection unit 12 is matched with the first connection unit 11 to connect the mask plate transport box 1 and the overhead traveling crane 2. The second connection unit 12 includes a connection member mounting frame 121 fixedly arranged on the overhead traveling crane 2, two limited sliding connection members 122 symmetrically arranged on both sides of the connection member mounting frame 121, and two guide sliding connection members 123 symmetrically arranged on both sides of the connection member mounting frame 121.

[0024] The connector mounting frame 121 is fixedly arranged on the side of the overhead crane plate 2 facing the mask plate transport box 1. The connector mounting frame 121 is a square frame body that matches the length and width of the first connection unit 11, so that when the mask plate transport box 1 and the overhead crane plate 2 are connected together, the connector mounting frame 121 can surround the first connection unit 11 inside thereof to protect the connection structure between the first connection unit 11 and the second connection unit 12. The connector mounting frame 121 is used to set the limit sliding connector 122 and the guide sliding connector 123.

[0025] The two limiting sliding connectors 122 are symmetrically arranged at the two side edges of the connector mounting frame 121, and the two limiting sliding connectors 122 are arranged corresponding to the limiting clamping slider 111. Each limiting sliding connector 122 includes a limiting member 1221, a guide bar 1222 arranged at the end of the limiting member 1221 toward one end of the guiding sliding connector 123, and a second limiting protrusion 1223 arranged at one end of the guide bar 1222.

[0026] The outer contours of the two limit members 1221 are both L-shaped, and the two limit members 1221 are arranged opposite to each other. That is, the opening directions of the two limit members 1221 are both toward one side of their symmetry axis. The guide bar 1222 is fixedly arranged at one end of the limit member 1221 close to the guide sliding connection member 123, and is flush with the edge of one side of the opening direction of the limit member 1221. The second limit protrusion 1223 is arranged at one end of the guide bar 1222 close to the guide sliding connection member 123, and is arranged on the side of the guide bar 1222 facing the crown plate 2.

[0027] When the mask plate transport box 1 is connected to the overhead crane plate 2, one end of the guide strip 1222 is inserted into the first clamping groove 1122, and the second limiting protrusion 1223 abuts against the side of the first clamping body 1111 facing the top of the mask plate transport box, and slides along the length direction of the first clamping body 1111 until the second limiting protrusion 1223 slides out of the first clamping body 1111. At this time, one side of the first clamping body 1111 is accommodated in the limiting member 1221, the first limiting protrusion 1113 abuts against the inner side wall of the connecting member mounting frame 121, and the second limiting protrusion 1223 abuts against one end of the first clamping body 1111 facing the guide clamping slider 112, so the first limiting protrusion 1113 and the second limiting protrusion 1223 jointly limit the overhead crane plate 2 in the relative direction, so that the position of the overhead crane plate 2 along its sliding direction is fixed.

[0028] The two guide sliding connectors 123 are symmetrically arranged on both sides of the connector mounting frame 121 where the limit sliding connector 122 is arranged, and are arranged corresponding to the guide clamping slider 112. The outer contours of the guide sliding connectors 123 are all arranged in an L shape, one side of the L shape is fixedly connected to the connector mounting frame 121, and the other side is arranged corresponding to the guide clamping slider 112. When the mask plate transport box 1 is connected to the overhead traveling plate 2, one side of the guide sliding connector 123 is accommodated in the second clamping groove 1122 and abuts against the side wall of the second clamping body 1121.

[0029] Therefore, the overhead crane plate connection mechanism fixedly connects the mask plate transport box 1 and the overhead crane plate 2 together through a first connection unit 11 arranged on the top of the mask plate transport box 1 and a second connection unit 12 arranged on the overhead crane plate 2. The first connection unit 11 is provided with a limit snap-in slider 111 and a guide snap-in slider 112. The second connection unit 12 is provided with the limit sliding connector 122 and the guide sliding connector 123. When the mask plate transport box 1 and the overhead crane plate 2 are connected together, the limit snap-in slider 111, the guide snap-in slider 112 and the limit sliding connector 122 and the guide sliding connector 123 are arranged corresponding to each other, and the limit snap-in slider 111 and the limit sliding connector 122, and the guide snap-in slider 112 and the guide sliding connector 123 can all be slidably snap-in together. The first limiting protrusion 1113 and the second limiting protrusion 1223 are used between the limiting clamping slider 111 and the limiting sliding connection member 122 to fix the moving position of the crane plate 2 along the length direction of the limiting clamping slider 111, that is, to limit the lateral displacement. At the same time, the first clamping body 1111, the second clamping body 1121, the limiting member 1221, and the guiding sliding connection member 123 are all arranged in an L row and are arranged corresponding to each other, so as to limit the position of the crane plate 2 along the length direction perpendicular to the first clamping body 1111, that is, to limit the longitudinal displacement. Therefore, the first connecting unit 11 and the second connecting unit 12 cooperate with each other to fix and lock the mask plate transport box 1 and the crane plate 2 together.

[0030] Compared with the prior art, the utility model provides a crane plate connection mechanism that is beneficial to improving the sealing of the mask plate transport box, which includes a mask plate transport box 1, a crane plate 2 fixedly connected to the top of the mask plate transport box 1, and a connection mechanism 10 arranged between the mask plate transport box 1 and the crane plate 2. The connection mechanism 10 includes a first connection unit 11 fixedly arranged on the top of the mask plate transport box 1, and a second connection unit 12 fixedly arranged on the side where the crane plate 2 is connected to the mask plate transport box 1. The first connection unit 11 includes two limit clamping sliders 111 symmetrically arranged on the top of the mask plate transport box 1, and two guide clamping sliders 112 symmetrically arranged on one side of the limit clamping slider 111. The second connection unit 12 includes a connector mounting frame 121 fixedly arranged on the crane plate 2, two limit sliding connectors 122 symmetrically arranged on both sides of the connector mounting frame 121, and two guide sliding connectors 123 symmetrically arranged on both sides of the connector mounting frame 121. When the mask plate transport box 1 is connected to the overhead travelling plate 2, the limit snap-fitting slider 111 corresponds to and snaps with the limit sliding connector 121, and the guide snap-fitting slider 112 corresponds to and snaps with the guide sliding connector 123, thereby fixing the mask plate transport box 1 to the overhead travelling plate 2. Therefore, the overhead travelling plate connection mechanism respectively sets the first connection unit 11 and the second connection unit 12 on the overhead travelling plate 2 and the mask plate transport box 1 in a punch-free manner, and designs the connection structure between the first connection unit 11 and the second connection unit 12 so that the connection between the first connection unit 11 and the second connection unit 12 is stable, thereby avoiding the damage of the mask plate transport box 1 to the screw hole in the screw connection method, thereby reducing the sealing of the mask plate transport box 1 and causing mask plate contamination.
