[0001] The utility model relates to the technical field of semiconductor production, in particular to a material trolley for transporting semiconductor modules. Background Art
[0002] In recent years, with the rapid development and transfer of the global electronics manufacturing industry, the market size of China's semiconductor industry has continued to grow. At the same time, domestic semiconductor companies are also actively planning and increasing R&D investment to enhance the competitiveness of domestic semiconductor products. During the production process of semiconductor modules, semiconductor module materials need to be frequently transported between different processes and equipment. The use of material trolleys can quickly and efficiently transfer materials from one location to another, reducing the time and labor intensity of manual handling, thereby improving overall production efficiency.
[0003] However, existing material carts are usually only equipped with three or four frames for placing materials, and the height of these frames is often fixed. This design limits the applicability of the cart when transporting large materials, because such materials can usually only be placed in the top frame of the cart. In addition, when multiple materials are placed in the same frame, they are prone to collide with each other during transportation, which may cause damage to the materials. Utility Model Content
[0004] In order to overcome the above-mentioned shortcomings in the prior art, the utility model provides a material cart for transporting semiconductor modules.

It also includes a sliding frame, a pad, a locking assembly and a partitioning assembly. The sliding frame is slidably connected between the middle parts of the four columns, and pads are provided in the middle of the first fixed frame, the second fixed frame and the sliding frame. A locking assembly for positioning the height of the sliding frame is provided between the four columns, and a partitioning assembly for separating materials is provided between the first fixed frame, the second fixed frame and the sliding frame.
[0006] As an improvement of the above scheme, the locking assembly includes a first fixed seat, a first insertion rod, a mounting seat, a two-way screw rod, a connecting plate and a hand-tightening nut.

The bottom of the sliding frame is symmetrically fixedly connected with the mounting seat left and right, and a two-way screw rod is rotatably connected between the two mounting seats. The adjacent ends of the first insertion rods on the left and right sides are fixedly connected with the connecting plate, and the two-way screw rod passes through the two connecting plates respectively and is threaded with them. The right end of the two-way screw rod is fixedly connected with a hand-tightening nut, and a plurality of first jacks that are adapted to the first insertion rods are arranged at intervals on the column.
[0007] As an improvement to the above-mentioned scheme, the partition assembly includes a partition plate, and two first card slots are provided on the front sides of the tops of the first fixed frame, the second fixed frame and the sliding frame, and two second card slots are provided on the rear sides of the tops of the first fixed frame, the second fixed frame and the sliding frame.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] Embodiment: A material cart for transporting semiconductor modules, such as Figures 1-4 As shown, it includes a first fixed frame 1, a column 2, a second fixed frame 3, a universal wheel 5 and a handle 51. The top of the first fixed frame 1 is welded and fixed with four columns 2 at intervals, and the second fixed frame 3 is welded and fixed between the tops of the four columns 2. The bottom of the first fixed frame 1 is fixed with four universal wheels 5 at intervals by bolts, and the top right side of the second fixed frame 3 is welded and fixed. It also includes a sliding frame 4, a pad 52, a locking assembly and a partition assembly. The sliding frame 4 is slidably connected between the middle parts of the four columns 2. The middle parts of the first fixed frame 1, the second fixed frame 3 and the sliding frame 4 are all provided with a downwardly concave material placement area for placing materials, and the length and width of these material placement areas are equal. The middle parts of the first fixed frame 1, the second fixed frame 3 and the sliding frame 4 are all provided with a pad 52, and the pad 52 is made of anti-static material. A locking assembly for positioning the height of the sliding frame 4 is provided between the four columns 2, and a partition assembly for separating materials is provided between the first fixed frame 1, the second fixed frame 3 and the sliding frame 4.
[0019] like Figure 2As shown, the locking assembly includes a first fixing seat 61, a first insertion rod 62, a mounting seat 63, a bidirectional screw rod 64, a connecting plate 65 and a hand-tightening nut 66. The left and right sides of the bottom of the sliding frame 4 are symmetrically welded and fixed with the first fixing seat 61. The first insertion rod 62 is slidably set in the four first fixing seats 61. The mounting seat 63 is symmetrically welded and fixed at the bottom of the sliding frame 4. A bidirectional screw rod 64 is rotatably connected between the two mounting seats 63. The adjacent ends of the first insertion rods 62 on the left and right sides are fixedly connected to the connecting plate. 65. The two-way screw rod 64 passes through the two connecting plates 65 respectively and cooperates with them with threads. The threads of the two-way screw rod 64 are set on its left and right sides and are mirrored. When the two-way screw rod 64 rotates, it can drive the two connecting plates 65 to move closer to or away from each other. The right end of the two-way screw rod 64 is clamped and fixed with a hand nut 66. A plurality of first insertion holes 67 adapted to the first insertion rod 62 are provided at intervals on the column 2. The first insertion rod 62 can be inserted into adjacent first insertion holes 67 to position the height of the sliding frame 4.
[0020] like Figures 1-4 As shown, the partition assembly includes a partition plate 72, the first fixed frame 1, the second fixed frame 3 and the sliding frame 4 are all provided with two first card slots 711 on the top front side, the first fixed frame 1, the second fixed frame 3 and the sliding frame 4 are all provided with two second card slots 71 on the top rear side, the first fixed frame 1, the second fixed frame 3 and the sliding frame 4 are movably provided with two partition plates 72 through the first card slot 711 and the second card slot 71, the partition plate 72 is made of antistatic material, the first card slot 711 runs through the front side of the first fixed frame 1, the second fixed frame 3 and the sliding frame 4 When the lock is unlocked, the lock 72 is unlocked, and the lock 72 is unlocked, so the lock 72 is unlocked. When the lock 72 is unlocked, the lock 72 is unlocked, and the lock 72 is unlocked. Figure 2 As shown), the portion of the partition plate 72 with the square opening 74 is exposed outside the slot 73, so that the staff can easily pull the partition plate 72 out of the slot 73 by hooking the square opening 74.
[0021] Initially, the two partition plates 72 are respectively placed in the two slots 73 preset on the first fixed frame 1. The staff pushes the material cart to the semiconductor module material stacking area, and stacks the semiconductor modules in the material placement areas set on the first fixed frame 1, the second fixed frame 3 and the sliding frame 4. Since the length and width of these material placement areas are equal, and the length of a single semiconductor module is slightly smaller than the width of the material placement area, and the length of a single semiconductor module is slightly less than one-third of the length of the material placement area, the staff usually stacks three stacked semiconductor modules in an interval manner in the material placement area. After the staff has placed the semiconductor modules in the material placement areas of the first fixed frame 1, the second fixed frame 3 and the sliding frame 4 respectively, the two partition plates 72 are pulled out from the slots 73, and are clamped between the first fixed frame 1, the sliding frame 4 and the second fixed frame 3 respectively through the first card slot 711 and the second card slot 71. In this way, the three stacked semiconductor modules in the same material placement area can be separated (such as Figure 1 As shown), the two adjacent stacks of semiconductor modules are prevented from being damaged due to collision during transportation. If other larger materials need to be transported, the staff can rotate the bidirectional screw rod 64 by holding the hand-tightening nut 66. The rotation of the bidirectional screw rod 64 will push the two connecting plates 65 to move toward each other, so that the four first insertion rods 62 are respectively disengaged from the adjacent first insertion holes 67, thereby releasing the sliding limit of the sliding frame 4. At this time, the staff can slide the sliding frame 4 upward along the four columns 2 to the desired height, and then reverse the bidirectional screw rod 64 to insert the four first insertion rods 62 into the first insertion holes 67 that match this height, thereby adjusting the height of the sliding frame 4. In this way, larger materials can be placed in the first fixed frame 1 and the second fixed frame 3, thereby increasing the applicability of the material trolley.
[0022] like Figure 1 and Figure 4 As shown, it also includes a second fixed seat 81, a second plug rod 82, a fixing plate 83 and a return spring 84. Two second fixed seats 81 are welded and fixed at intervals on the front side of the second fixed frame 3. Second plug rods 82 are slidably set in the two second fixed seats 81. The ends of the two second plug rods 82 close to each other are welded and fixed with fixing plates 83. Reset springs 84 are connected between the two fixing plates 83 and the adjacent second fixed seats 81. Second insertion holes 85 are opened on the two partition plates 72. The two second insertion rods 82 can be inserted into the adjacent second insertion holes 85 to fix and limit the partition plates 72.
[0023] By setting the second fixing seat 81, the second insertion rod 82 and the fixing plate 83, etc., before the staff installs the two partition plates 72, they first pinch the two fixing plates 83 to bring the two fixing plates 83 close to each other, thereby driving the two second insertion rods 82 close to each other and stretching the two reset springs 84. Then, the two partition plates 72 are installed respectively, and the two fixing plates 83 are loosened. Under the reset action of the reset springs 84, the two second insertion rods 82 will be respectively inserted into the second insertion holes 85 set on the two partition plates 72 to fix and limit the two partition plates 72. This can prevent the two partition plates 72 from falling off due to factors such as vibration during transportation.
[0024] like Figure 4 As shown, a pad 9 is also included, and the two columns 2 on the left are both glued and fixed with pads 9 at intervals above and below.
[0025] By setting the pad 9, when the staff pushes the material trolley to the dedicated placement area, since the placement area is generally set next to the wall, the pad 52 can protect the left side of the material trolley from colliding with the wall, thereby avoiding damage to the wall or the material trolley.
[0026] like Figure 1 As shown, a clamping sleeve 10 is also included, and the clamping sleeve 10 is adhesively fixed to the right side of the second fixing frame 3.
[0027] By providing the card sleeve 10 and inserting the card with the material trolley information therein, the material trolley can be conveniently identified and managed to avoid mixing.
[0028] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
