[0001] The invention relates to the technical field of chip processing, and in particular to an automatic loading and unloading device for a clip loaded with chip originals. Background Art

[0002] Chip originals are products of an important stage in the semiconductor manufacturing process and usually go through a series of post-processing steps, such as cleaning, testing, marking, etc. The automatic loading and unloading device for the clips that load chip originals is one of the important equipment in the chip original processing process.

[0003] Existing chip original pieces usually place the processed original pieces together, transfer the original pieces to a specified position through a loading and unloading device, and after moving to a specific position, the original piece is pushed by a pushing device through the induction cooperation of the sensor to complete the loading.

[0004] However, the above-mentioned loading and unloading device will place multiple original sheets in parallel up and down. In order to ensure the fixation of the original sheets, multiple original sheets need to be clamped, but this will result in the original sheets being unable to be quickly unloaded when being pushed, which can easily cause wear on the edges of the original sheets.

The elastic strip is fixedly connected to the upper end of the sliding plate, and the upper end of the elastic strip is fixedly connected to the top wall of the placement box. The sliding plate is slidably arranged inside the sliding space. Multiple side strips are fixedly connected to one side of the sliding plate close to the middle of the placement box and are respectively arranged on the upper sides of multiple limiting grooves. Multiple rollers are rotatably installed on one side of the sliding plate close to the middle of the placement box and are respectively located inside multiple strip grooves.

[0010] Preferably, a positioning assembly is provided between the transmission belt and the placement box, and the positioning assembly is used to fix the position of the placement box above the transmission belt.

[0011] Preferably, the positioning assembly includes a plurality of magnetic strips and a plurality of magnetic blocks, the plurality of magnetic strips are equidistantly sleeved on the transmission belt, and the plurality of magnetic blocks are fixedly connected to the bottom of the placement box and are magnetically connected to the magnetic strips.

[0012] Preferably, a guide block is fixedly connected inside the mounting frame, the guide block is close to the discharging end of the transmission belt, the inner side of the guide block close to the transmission belt is arranged in an arc shape and fits with the side of the transmission belt, and the side of the guide block away from the transmission belt is arranged as a mounting platform;

[0013] The guide block is arranged obliquely on the upper side close to the transmission belt and is provided with a plurality of guide grooves, and the positions of the guide grooves are arranged corresponding to the positions of the magnetic strips.

[0014] Preferably, a lifting assembly is provided on the installation platform, and the lifting assembly is used to drive the placement box to move up and down.

[0015] Preferably, the lifting assembly includes two telescopic columns, a base plate, a placement plate and a baffle, the two telescopic columns are vertically fixedly connected to the mounting platform, the base plate is fixedly connected to the upper end of the telescopic columns, the placement plate is arranged on the upper side of the base plate, and a plurality of slots corresponding to the magnetic blocks are opened on the placement plate, and the baffle is vertically fixedly connected to the side of the placement plate away from the transmission belt.

[0016] Preferably, an extrusion bag is provided between the bottom plate and the placement plate, and the extrusion bag is a flat-plate bag filled with gas.

[0017] Preferably, a lifting assembly is provided between the adjusting assembly and the extrusion bag, and the lifting assembly is used to lift the sliding plate upwards.

[0018] Preferably, the lifting assembly includes two elastic bags, two lifting blocks and two connecting blocks. Two placement openings are symmetrically opened on the placement plate. The two elastic bags are symmetrically connected to the extrusion bag and are located inside the placement openings. The lifting block is fixedly connected to the upper ends of the two elastic bags. The two connecting blocks are fixedly connected between the two sliding plates and are respectively located on the bottom sides of the two ends of the sliding plates. The lifting block moves upward to push the connecting block to move upward.

[0019] Preferably, when the placement box is moved onto the placement plate, the vertical positions of the top block and the connection block correspond, and a limit bar is provided inside the placement opening, and the limit bar is used to limit the position of the top block.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. After the original sheet is placed in the limiting groove, release the squeeze on the sliding plate to move the side strip downward to fix the position of the original sheet and prevent the original sheet from sliding and falling from the limiting groove during movement. When the original sheet in the placement box is ready to be taken out, push the sliding plate upward to separate the side strip from the original sheet, and move the rollers on both sides to the bottom of the original sheet. In the process of pushing the original sheet, the friction on the original sheet can be reduced, which increases the transfer speed and avoids wear on both sides of the original sheet.

[0022] 2. When placing the placement box on the conveyor belt, there will be deviations in the placement position during manual placement and movement of the placement box. In order to ensure the subsequent pushing of the original piece inside the placement box, the position of the placement box needs to be positioned. Through the magnetic connection between the magnetic block and the magnetic strip, the position of the placement box can be fixed when it is placed, and the movement during the movement can be avoided, so that the placement box can be moved to the specified position;

[0023] 3. By controlling the telescopic column to drive the upper bottom plate and the placement plate to move upward, the original sheet located below is moved upward and moved to the pushing position, thereby ensuring the orderly pushing of the original sheet and improving the loading and unloading speed of the original sheet;

[0024] 4. When a placement box with a large number of original pieces is moved to the placement board, the export block is tilted, and the exported placement box will generate a certain impact force. At the same time, the impact force generated by the collision is reduced and buffered by squeezing the squeezing capsule, thereby avoiding a large impact of the placement box on the placement board;

[0025] 5. As the weight of the placement box acts on the squeezing bag, the squeezing bag is squeezed and deformed, the elastic bag is inflated and deformed, the top block is pushed upward, and the top block and the connecting block are squeezed and moved upward, thereby driving the sliding plate to push upward, changing the placement position of the original piece, thereby ensuring the rapid pushing of the original piece;

[0026] 6. In the process of pushing the original piece, some friction will be generated, which may easily cause the position of the placement box to shift. The two sides of the placement box are restricted and fixed by the raised top blocks on both sides to ensure that the position of the placement box will not move when the original piece is pushed, thereby ensuring that the original piece can be pushed out completely every time.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0039] Reference Figure 1-Figure 9 , an automatic loading and unloading device for a clip loaded with chip originals, comprising a U-shaped mounting frame 1, a transmission belt 2 installed in the middle of the mounting frame 1 and a placing box 3 for placing originals, the placing box 3 is a rectangular box, and both ends are set to be open, and a plurality of limiting grooves 11 are symmetrically opened on both sides of the placing box 3, the limiting grooves 11 are used to place the originals, and a strip groove is opened below the limiting grooves 11;

[0040] Two sliding spaces 12 are symmetrically provided on both sides of the placing box 3. The sliding spaces 12 are provided up and down to connect the plurality of limiting grooves 11. An adjusting component 4 is provided inside the sliding space 12. The two symmetrically provided adjusting components 4 are used to adjust the position of the original piece inside the limiting groove 11.

[0041] The adjustment component 4 includes an elastic strip 41, a sliding plate 42, multiple side strips 43 and multiple rollers 44. The elastic strip 41 is fixedly connected to the upper end of the sliding plate 42, and the upper end of the elastic strip 41 is fixedly connected to the top wall of the placement box 3. The sliding plate 42 is slidably arranged inside the sliding space 12. Multiple side strips 43 are fixedly connected to one side of the sliding plate 42 close to the middle of the placement box 3, and are respectively arranged on the upper side of multiple limit grooves 11. Multiple rollers 44 are rotatably installed on one side of the sliding plate 42 close to the middle of the placement box 3, and are respectively located inside multiple strip grooves.

[0042] In the embodiment of the above technical solution, when placing the original piece into the placing box 3, the sliding plate 42 is first moved upward to squeeze and deform the elastic strip 41, thereby expanding the distance between the bottom surface of the side strip 43 and the bottom surface of the limiting groove 11 to form a clamping space. This clamping space can be adjusted, so that original pieces of various thicknesses can be placed inside the placing box 3, expanding the use range of the placing box 3 for placing original pieces. After the two sides of the original piece are respectively clamped in the corresponding limiting grooves 11 on both sides, the squeezing of the sliding plate 42 is released, and the side strips 43 move downward and reset under the elastic action of the elastic strips 41. The side of the side strip 43 close to the original piece is set to be elastic, so as to squeeze and fix the upper surface of the original piece, complete the fixation of the original piece inside the clamping space, and prevent the original piece from sliding and falling from the limiting groove 11 during the movement.

[0043] When the original sheet in the placing box 3 is about to be unloaded, the sliding plate 42 is pushed upward to squeeze the elastic strip 41, thereby separating the side strip 43 from the original sheet. At the same time, when the sliding plate 42 moves upward, the rollers 44 on both sides are moved to the bottom of the original sheet. In the process of pushing the original sheet, the friction on the original sheet can be reduced, and the wear on both sides of the original sheet can be avoided while increasing the transfer speed.

[0044] The present invention can ensure the fixation of the original sheet and improve the lead-out speed of the original sheet during loading and unloading, thereby improving the loading and unloading rate.

[0045] The preferred technical solution in this embodiment is:

[0046] Reference Figure 1-3 A positioning assembly 5 is provided between the transmission belt 2 and the placement box 3 , and the positioning assembly 5 is used to fix the position of the placement box 3 above the transmission belt 2 .

[0047] The positioning assembly 5 includes a plurality of magnetic strips 51 and a plurality of magnetic blocks 52 . The plurality of magnetic strips 51 are equidistantly sleeved on the transmission belt 2 . The plurality of magnetic blocks 52 are fixedly connected to the bottom of the placement box 3 and are magnetically connected to the plurality of magnetic strips 51 .

[0048] When placing the placement box 3 on the transmission belt 2, there will be deviations in the placement position due to manual placement of the placement box 3 and the movement of the placement box 3. In order to ensure the subsequent pushing of the original piece inside the placement box 3, the position of the placement box 3 needs to be positioned. Through the magnetic connection between the magnetic block 52 and the magnetic strip 51, the position can be fixed when the placement box 3 is placed, and at the same time, the displacement of the placement box 3 during the movement can be avoided, and finally the placement box 3 is moved to the specified position.

[0049] Reference Figure 3-4 A guide block 6 is fixedly connected inside the mounting frame 1. The guide block 6 is close to the discharge end of the transmission belt 2. The end of the guide block 6 close to the transmission belt 2 is internally arranged in an arc shape and fits with the side of the transmission belt 2. The side of the guide block 6 away from the transmission belt 2 is arranged as a mounting platform; the guide block 6 is inclined above the side close to the transmission belt 2 and is provided with a plurality of guide grooves, and the positions of the guide grooves are arranged corresponding to the positions of the magnetic strips 51.

[0050] When the placement box 3 moves with the transmission belt 2 to the discharge end of the transmission belt 2, the placement box 3 is separated from the transmission belt 2 by the lead-out block 6 that fits with the transmission belt 2, and at the same time, it is limited by the guide groove and the magnetic block 52 under the placement box 3. Since the upper surface of the lead-out block 6 is inclined, the placement box 3 will slide downward along the lead-out block 6, thereby separating the placement box 3 from the transmission belt 2.

[0051] Reference Figure 8-9 A lifting assembly 7 is provided on the installation platform, and the lifting assembly 7 is used to drive the placement box 3 to move up and down.

[0052] The lifting assembly 7 includes two telescopic columns 71, a base plate 72, a placement plate 73 and a baffle 74. The two telescopic columns 71 are vertically fixedly connected to the mounting platform, the base plate 72 is fixedly connected to the upper end of the telescopic columns 71, the placement plate 73 is arranged on the upper side of the base plate 72, and a plurality of slots corresponding to the magnetic block 52 are opened on the placement plate 73, and the baffle 74 is vertically fixedly connected to the side of the placement plate 73 away from the transmission belt 2.

[0053] Since the position of the original sheet is sensed and located by sensors during loading and unloading, after the original sheet on the upper side is pushed out, the placement box 3 needs to be moved upward. At this time, the telescopic column 71 is controlled to drive the upper bottom plate 72 and the placement plate 73 to move upward, thereby moving the original sheet located below upward and moving the original sheet to the pushing position, thereby ensuring the orderly pushing of the original sheet and improving the loading and unloading rate of the original sheet.

[0054] An extrusion bag 8 is arranged between the bottom plate 72 and the placement plate 73. The extrusion bag 8 is a flat-plate bag filled with gas.

[0055] When the placement box 3 containing a large number of original sheets moves onto the placement plate 73, since the export block 6 is set at an angle, the exported placement box 3 will generate a certain impact force, while reducing the impact force generated by the collision and buffering it by squeezing the squeezing bag 8, thereby avoiding the placement box 3 from having a large impact on the placement plate 73.

[0056] A lifting assembly 9 is provided between the adjustment assembly 4 and the extrusion capsule 8, and the lifting assembly 9 is used to lift the sliding plate 42 upward. The lifting assembly 9 includes two elastic capsules 91, two lifting blocks 92 and two connecting blocks 93. Two placement openings are symmetrically opened on the placement plate 73. The two elastic capsules 91 are symmetrically connected to the extrusion capsule 8 and are located inside the placement openings. The lifting blocks 92 are fixedly connected to the upper ends of the two elastic capsules 91. The two connecting blocks 93 are fixedly connected between the two sliding plates 42 and are respectively located at the bottom sides of the two ends of the sliding plates 42. The lifting blocks 92 move upward to push the connecting blocks 93 to move upward.

[0057] When the placement box 3 is moved onto the placement plate 73 , the vertical positions of the top block 92 and the connecting block 93 correspond, and a limiting strip 10 is provided inside the placement opening, and the limiting strip 10 is used to limit the position of the top block 92 .

[0058] After the placement box 3 falls onto the placement plate 73, the weight of the placement box 3 acts on the squeezing bag 8, squeezing and deforming the squeezing bag 8, thereby squeezing the gas inside the squeezing bag 8 into the elastic bag 91, causing the elastic bag 91 to be inflated and deformed, pushing the top block 92 upward, and squeezing and moving upward through the top block 92 and the connecting block 93, thereby driving the sliding plate 42 to push upward, changing the placement position of the original piece, thereby ensuring that the original piece is pushed quickly.

[0059] Since some friction will be generated in the process of pushing the original sheet, it is easy to cause the position of the placement box 3 to shift. After the placement box 3 shifts, it is easy to cause the normal pushing of the subsequent original sheet. At the same time, the two sides of the placement box 3 are restricted and fixed by the raised top blocks 92 on both sides to ensure that the position of the placement box 3 will not move when the original sheet is pushed, thereby ensuring that the original sheet can be pushed out completely every time.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
