Description

TECHNICAL FIELD

[0001] The utility model relates to the mask manufacturing field, concretely relates to a kind of auxiliary positioning mechanism for mask automatic unpacking. BACKGROUND

[0002] In the mask manufacturing field, the particles in the environment have a pivotal influence on the whole process technology and product yield, and the particles falling on the raw material in the photoetching process link will finally appear chromium residue on the product, which needs to spend a lot of time and effort to repair by laser ZAP, and even lead to product scrap seriously. In order to improve product quality, the control of particles in the whole process link is particularly important, among which, the risk of manual loading and unloading link in the process of up and down mask of each station is the largest. With the progress of science and technology, each mask manufacturer starts to use automatic handling trolley (AGV) for automatic taking and placing and transportation for large-size mask, instead of manual up and down mask handling to reduce particle pollution.

[0003] However, there is a constraint factor in the process of AGV taking and placing, that is, the program of grabbing mechanical arm is fixed, and the position of the object to be grabbed is relatively fixed, and there is no large deviation each time, otherwise there is the risk of colliding mask in mechanical hand taking and placing. For each process station, the shape and position of the raw material box are fixed, and the mechanical hand has no difficulty in grabbing. However, for the mask of raw material state, it is loaded by raw material box after being delivered to the factory, and it is necessary to unpack the mask of raw material from the box to the fixed raw material box loading by AGV loading. This process is generally called unpacking. The unpacking link operation process is as follows: placing raw material box on unpacking platform→adjusting the position of raw material box to center up and down and left and right→opening the upper cover of raw material box→setting different size grabbing plate for mechanical hand.

[0004] In the unpacking process, there are the following shortcomings:

[0005] 1. It is difficult to realize the center positioning of raw material box of different sizes. The conventional method is to independently develop a set of auxiliary positioning and placing platform mechanism for different sizes, and fixed buckle is used to limit the position of raw material box. The disadvantage is that multiple placing platforms need to be developed, and the development cost is high.

[0006] 2. In the unpacking process, after placing raw material box on unpacking platform, due to the gravity of large-size mask of more than one hundred kilograms and the friction between raw material box and platform, it is difficult to move, and the bottom of box body is easy to scratch, which affects the appearance of box body.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the utility model is further described in detail below in combination with examples and drawings. The illustrative embodiment of the utility model and its description are only used to explain the utility model, and do not limit the utility model.

[0039] In the prior art, due to the oversize mask, an automatic guided vehicle (AGV) is needed to automatically take, place and transport, instead of manual up and down mask handling to reduce particle pollution. However, there is a constraint factor in the AGV taking and placing process, that is, the program of the grabbing mechanical arm is fixed, and the position of the grabbing object needs to be relatively fixed. However, in the unpacking process, the following disadvantages exist: in the unpacking process, after the raw material box is placed on the unpacking platform 1, due to the gravity of the oversize mask reaching hundreds of kilograms and the friction between the raw material box and the platform, it is difficult to move, and the bottom of the box is easy to scratch, affecting the appearance of the box.

[0040] The embodiment provides an auxiliary positioning mechanism for automatic unpacking of a mask, as shown in Figures 1-2 The auxiliary positioning mechanism comprises a unpacking platform 1, a sliding assembly and a handrail 6.

[0041] The unpacking platform 1 is used for supporting and placing a raw material box, and the raw material box is positioned and fixed on the unpacking platform 1 to be moved to a mechanical hand position for accurate grabbing.

[0042] The sliding assembly is arranged on the unpacking platform 1 and is used for driving the raw material box to slide on the unpacking platform 1. Since the gravity of the oversize mask reaches hundreds of kilograms and the friction between the raw material box and the unpacking platform 1 is large, it is difficult to move. The sliding assembly in the embodiment comprises a plurality of sliding parts 2, each sliding part 2 comprises a roller 21 and two support seats 22,

[0043] The two support seats 22 are fixedly arranged on the unpacking platform 1.

[0044] The roller 21 is arranged perpendicular to the feeding direction of the raw material box, and the roller 21 is rotationally arranged between the two support seats 22.

[0045] Specifically, the arrangement of the rollers 21 reduces the friction between the raw material box and the unpacking platform 1, and the gaps between the rollers 21 are arranged to ensure the stable movement of the raw material box while reducing the number of rollers 21 and saving costs. In addition, due to the large size of the raw material box, a plurality of sliding parts 2 are symmetrically arranged on both sides of the unpacking platform 1 to facilitate the stable movement of the raw material box. In the embodiment, the number of sliding parts 2 is 10, that is, there are 5 sliding parts 2 arranged on each side of the unpacking platform 1. It can be known that the number of sliding parts 2 can be arranged according to the specific size of the unpacking platform 1 and the raw material box.

[0046] The positioning assembly includes a transverse positioning part 3 and a longitudinal positioning part 4 for center positioning of the four sides of the raw material box. Specifically, the transverse positioning part 3 positions the left and right sides of the raw material box, and the longitudinal positioning part 4 positions the front and rear sides of the raw material box.

[0047] Further, the unpacking platform 1 is provided with universal wheels 5 at the bottom. During unpacking, the channel for grabbing by the mechanical hand is narrow, and the raw material box needs to be placed in a relatively spacious area before being transferred to the unpacking platform 1, and then transferred to the position to be grabbed. To this end, the embodiment ensures the convenient transportation of the device by providing universal wheels 5 at the bottom of the unpacking platform 1, thereby facilitating the operator to load the raw material box to the transfer channel of the mechanical hand to solve the existing problem.

[0048] Further, the transverse positioning pad 32, the longitudinal positioning pad 42 and the roller 21 are all made of Teflon material. Teflon material has excellent wear resistance under high load and can withstand high-strength wear and impact to avoid scratching of the box body.

[0049] Further, the unpacking platform 1 is provided with a handrail 6 on one side. In the embodiment, the handrail 6 is arranged on the left side of the unpacking platform 1, and the handrail 6 has a certain height to facilitate the operator to hold and push.

[0050] Embodiment 2

[0051] In the prior art, it is difficult to center the raw material box of different sizes. The conventional method is to independently develop a set of auxiliary positioning and placing platform mechanism for different sizes, and fixed buckles are used to limit the position of the raw material box. The disadvantage is that multiple placing platforms need to be developed, which has high development cost.

[0052] To solve the above-mentioned defects, the embodiment is provided with a transverse positioning part 3 and a longitudinal positioning part 4.

[0053] The transverse positioning part 3 includes a transverse moving block 31, a transverse positioning pad 32 and a first driving member,

[0054] There are two lateral moving blocks 31, which are symmetrically arranged on both sides of the unpacking platform 1;

[0055] There are multiple lateral positioning pads 32, and the multiple lateral positioning pads 32 are respectively installed on the two lateral moving blocks 31. Specifically, two lateral positioning pads 32 are installed on the top of each lateral moving block 31.

[0056] The first driving member is connected to the two lateral moving blocks 31 and is used to drive the two lateral moving blocks 31 to move toward or away from each other.

[0057] Specifically, after the material box is placed on the unpacking platform 1, the first drive member is activated, and the two lateral movement blocks 31 begin to move toward each other, driving the lateral positioning pads 32 to move and contact the material box, pushing the material box to move and adjust to the center position. It can be seen that because the two lateral movement blocks 31 are symmetrically arranged, the two lateral movement blocks 31 always move symmetrically with the center position of the unpacking platform 1 as the symmetrical point, thereby ensuring the center positioning of the material box.

[0058] In addition, the first driving member includes a first bidirectional screw rod 71, a rotating rod 72, a transverse support frame 76 and a first manual rocker arm 73.

[0059] The rotating rod 72 and the first bidirectional screw rod 71 are arranged vertically, with the rotating rod 72 located above the first bidirectional screw rod 71. One end of the rotating rod 72 is connected to the first manual rocker arm 73. The rotating rod 72 and the first bidirectional screw rod 71 are transmission-connected in the following manner: the rotating rod 72 is provided with a driving bevel gear 74, and the first bidirectional screw rod 71 is provided with a driven bevel gear 75 that meshes with the driving bevel gear 74. The two transverse moving blocks 31 both slide on a transverse support frame 76, which is arranged on the unpacking platform 1.

[0060] In addition, the first bidirectional screw rod 71 is rotatably set at the bottom of the transverse support frame 76. The transverse support frame 76 is provided with a working hole. The first bidirectional screw rod 71 is transmission-connected to the rotating rod 72 through the working hole. The threads on both sides of the first bidirectional screw rod 71 have opposite rotation directions and are respectively threadedly connected to the two transverse moving blocks 31. Specifically, a first connecting block 77 is provided on one side of the two transverse moving blocks 31. The two first connecting blocks 77 are both threadedly connected to the first bidirectional screw rod 71 across the transverse support frame 76.

[0061] Thus, when the first bidirectional screw rod 71 rotates, the two transverse moving blocks 31 move toward each other. Conversely, when the first bidirectional screw rod 71 rotates in the opposite direction, the two transverse moving blocks 31 move away from each other.

[0062] Furthermore, the longitudinal positioning portion 4 includes a longitudinal moving block 41, a longitudinal positioning pad 42 and a second driving member.

[0063] The number of the longitudinal moving blocks 41 is two, and the two longitudinal moving blocks 41 are symmetrically arranged on both sides of the unpacking platform 1.

[0064] The number of the longitudinal positioning pads 42 is multiple, and the multiple longitudinal positioning pads 42 are respectively installed on the two longitudinal moving blocks 41.

[0065] The second driving member is connected with the two longitudinal moving blocks 41, and is used for driving the two longitudinal moving blocks 41 to move towards or away from each other.

[0066] Specifically, after the raw material box is placed on the unpacking platform 1, the second driving member is started, and the two longitudinal moving blocks start to move towards each other, drive the longitudinal positioning pads 42 to move and abut against the raw material box and push the raw material box to move and adjust to the central position. It can be known that, since the two longitudinal moving blocks 41 are symmetrically arranged, the two longitudinal moving blocks 41 always align with the central position of the unpacking platform 1 as the symmetric point, so as to ensure the central positioning of the front and rear positions of the raw material box.

[0067] In addition, the second driving member includes a second bidirectional screw rod 81, a longitudinal supporting frame 83 and a second manual rocker arm 82,

[0068] Specifically, the second bidirectional screw rod 81 is arranged in parallel with the rotating rod 72, the rotating rod 72 and the second bidirectional screw rod 81 are rotationally arranged in the longitudinal supporting frame 83, the longitudinal supporting frame 83 penetrates through the central frame and the longitudinal supporting frame 83 is located above the transverse supporting frame 76, and in addition, the second manual rocker arm 82 is arranged at one end of the second bidirectional screw rod 81.

[0069] In addition, the two sides of the second bidirectional screw rod 81 are oppositely threaded, and are respectively threadedly connected with the two longitudinal moving blocks 41. Specifically, the two sides of the two transverse moving blocks 31 are provided with second connecting blocks, and one of the second connecting blocks penetrates through the transverse supporting frame 76 and is threadedly connected with the first bidirectional screw rod 71. Thus, when the second bidirectional screw rod 81 rotates, the two longitudinal moving blocks move towards each other. Conversely, when the second bidirectional screw rod 81 reversely rotates, the two longitudinal moving blocks 41 move away from each other.

[0070] It can be known that, through the transmission of the rotating rod 72 and the first bidirectional screw rod 71, the first manual rocker arm 73 and the second manual rocker arm 82 are in the same direction, which ensures the convenience of the operation of the worker.

[0071] In addition, in order to ensure that the transverse positioning pad 32 can abut against the raw material box and push the raw material box to move after moving, the transverse positioning pad 32 and the longitudinal positioning pad 42 in the embodiment are both L-shaped structures.

[0072] Further, one of the lateral moving blocks 31 is detachably connected with the corresponding lateral positioning pad 32. Since the raw material box needs to enter from one side of the unpacking platform 1, in order to facilitate the safe entry of the raw material box, in the embodiment, as shown in the drawings, the lateral positioning pad 32 on the lateral moving block 31 on the right side is removed before the raw material box is placed in, and after the raw material box is placed in, the lateral positioning pad 32 is reinstalled. Specifically, the detachable connection can be clamping, bonding, threaded connection and the like. Figure 1

[0073] The above specific embodiments further specifically describe the purpose, technical scheme and beneficial effects of the utility model, and it should be understood that the above description is only a specific embodiment of the utility model and is not used to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement and the like within the spirit and principle of the utility model should be included in the protection scope of the utility model.​
