Description

Technical Field

[0001] The present invention relates to the field of semiconductor processing technology. More specifically, the present invention relates to a glass carrier cassette loading and unloading device. Background Art

[0002] MipLED is a kind of LED display technology based on chip-level packaging. Its core is a technical solution that forms a high-precision display module through cutting, packaging, and integration of micro LED chips. Its production process mainly includes chip transfer and packaging, cutting and spectral separation processing, and module assembly. By using the mass transfer technology, Micro / Mini LED chips are transferred from the wafer to the carrier board, and electrical connection and fixation are achieved through photolithography or fan-out packaging technology. Then, the packaged panel is cut into single or multi-in-one small chips, and pixel points with consistent color and brightness are selected through the spectral mixing process to ensure that the display consistency reaches the cinema-level color gamut standard. Finally, the processed chips are soldered to the PCB board using SMT chip mounting technology to complete the production of the display module.

[0003] In the semiconductor industry, the production of MipLED requires the use of glass carriers as processing substrates, and these glass carriers are usually stored in standard cassettes for easy transportation and processing. Currently, the loading and unloading processing of glass carriers mainly relies on manual or semi-automatic operations. Manual operations have a large number of repetitive operations. It is necessary to manually take out the glass carriers one by one and put them into the processing equipment, or put the processed carriers back into the cassette one by one, resulting in long operation time and high labor intensity. In addition, errors are likely to occur during the manual operation process. For example, the position of the glass carrier is not accurately placed, which affects the subsequent processing accuracy. Moreover, a large number of repetitive operations waste human resources and reduce the overall production efficiency of the factory. Summary of the Invention

Detailed implementation manners

[0038] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following detailed implementation manners are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0039] Referring to the attached drawings of the specification Figures 1 to 12 , a glass slide cassette loading and unloading device, comprising: a housing 1, on which a lifting assembly 11 is provided, the output end of the lifting assembly 11 is equipped with a cassette conveying and positioning mechanism 2, the lifting assembly 11 is used to drive the cassette conveying and positioning mechanism 2 to move in a vertical straight line, a cassette 3 is arranged in the cassette conveying and positioning mechanism 2, the cassette 3 includes a frame 31, and a plurality of glass slides 33 are vertically and evenly arranged in the cassette 3, a loading and unloading conveying mechanism 4 is provided on the housing 1, and the loading and unloading conveying mechanism 4 is used to position and convey the cassette 3 into the cassette conveying and positioning mechanism 2;

[0040] A locking mechanism 5 is further provided on the housing 1, and the locking mechanism 5 is used to lock and unlock a plurality of glass slides 33, so as to realize the automatic locking and unlocking of the glass slides 33.

[0041] A material pulling mechanism 6 is further arranged on the housing 1. The material pulling mechanism 6 includes a track 61 and a pushing and pulling assembly 63, and the pushing and pulling assembly 63 can move linearly along the track 61. The pushing and pulling assembly 63 includes a pushing and pulling block 633 and a suction cup 634. The suction cup 634 is used for adsorbing and fixing the glass wafer 33. A material pushing mechanism 7 is arranged at the bottom of the loading and unloading conveying mechanism 4. The material pushing mechanism 7 is used for pushing the glass wafer 33 in the frame 31 to extend out of the frame 31. When the pushing and pulling assembly 63 moves linearly, the suction cup 634 can pull out the glass wafer 33 adsorbed and fixed from the frame 31, and the pushing and pulling block 633 can push the processed glass wafer 33 back into the frame 31.

[0042] It should be noted that the lifting assembly 11 is a linear motor, and the loading and unloading conveying mechanism 4 can be a conveying belt. By placing the cassette 3 containing the glass wafer 33 on the conveying belt, and then lifting the cassette 3 to an appropriate height by the linear motor, and then positioning and conveying the cassette 3 into the cassette conveying and positioning mechanism 2 through the conveying belt. The suction cup 634 can be connected to a vacuum pump. The air inside the suction cup 634 is pumped out by the vacuum pump to form a negative pressure between the suction cup 634 and the glass wafer 33, so as to realize the adsorption and fixation of the glass wafer 33. The processing of the glass wafer 33 can be carried out by a dicing machine. When loading, the glass wafer 33 is pulled to a designated position, and then the glass wafer 33 on the track 61 is taken away by the dicing machine for processing. After processing, the processed glass wafer 33 is placed back on the track 61. The suction cup 634 and the glass wafer 33 are flexibly connected, so that when the suction cup 634 adsorbs the glass wafer 33, the suction cup 634 and the glass wafer 33 can swing relative to each other, enabling it to tolerate the position change of the glass wafer 33 between the frame 31 and the track 61.

[0043] The specific implementation scenario is as follows: First, place the cassette 3 containing the glass slide 33 on the conveyor belt, then lift the cassette 3 to an appropriate height by a linear motor, and then position and convey the cassette 3 into the cassette conveying and positioning mechanism 2 through the conveyor belt. When discharging, first release the restriction on the glass slide 33 through the locking mechanism 5, then push a glass slide 33 out of the frame 31 by the pusher mechanism 7, then adsorb the glass slide 33 by the suction cup 634, and then pull out the adsorbed glass slide 33 from the frame 31 by the first pulling drive assembly 62 and pull the glass slide 33 to move on the track 61 to the designated position. Repeat the above method to achieve the individual discharging of the glass slides 33. Then, process the glass slides 33 by a dicing machine. After processing, transfer the processed glass slides 33 onto the track 61, and then collect the processed glass slides 33. When collecting, just adsorb the processed glass slide 33 by the suction cup 634 and drive the glass slide 33 to move in the direction close to the frame 31 by the first pulling drive assembly 62. When the glass slide 33 approaches the cassette 3, then push the glass slide 33 by the push-pull block 633 to make the glass slide 33 slide into the frame 31, thus realizing the automatic feeding and discharging of the glass slides 33. It is possible to discharge the glass slides 33 one by one when processing the glass slides 33, and after processing, collect the processed glass slides 33 one by one back into the frame 31.

[0044] In the above technical solution, currently when placing the glass slide 33 in the frame 31, a card slot 32 is usually opened on the frame 31 to place the glass slide 33 in the card slot 32 to avoid contact contamination between two adjacent glass slides 33. However, in order to facilitate the placement of the glass slide 33, the notch of the card slot 32 is usually larger than the size of the glass slide 33, which easily causes the glass slide 33 to slide laterally in the card slot 32. Although the locking mechanism 5 is set to lock the glass slide 33, during the discharging process, the glass slide 33 needs to be in an unlocked state. Then, when pushing the glass slide 33 out of the frame 31 by the pusher mechanism 7, it is very difficult to keep the vertical center line of the glass slide 33 consistent with the spacing center line of the track 61. And when adsorbing the glass slide 33 by the suction cup 634, if the contact position between the suction cup 634 and the glass slide 33 is not on the vertical center line of the suction cup 634, then during the process of pulling the glass slide 33 to move, it is very easy to cause the glass slide 33 to have a lateral offset angle. Furthermore, when the glass slide 33 moves on the track 61, it is easy to cause the edges and corners of the glass slide 33 to contact and collide with the side of the track 61, resulting in damage to the glass slide 33. For this reason, the present invention proposes a centering assembly 81, which clamps the extended section of the glass slide 33 pushed by the pusher mechanism 7 through the centering assembly 81 to keep the vertical center line of the glass slide 33 consistent with the spacing center line of the track 61. Specifically, refer to the attached instruction manual Figure 13With Figure 14 , a plurality of card slots 32 evenly distributed in the vertical direction are formed on both inner walls of the glass slide 33. The glass slide 33 is placed in the corresponding card slots 32. An adjusting mechanism 8 is provided at the feeding end of the track 61. The adjusting mechanism 8 includes a centering assembly 81. The centering assembly 81 includes a clamping assembly 811. The clamping assembly 811 is installed at the feeding end of the track 61. Two sliding seats 812 that can move synchronously and in opposite directions are installed at the output end of the clamping assembly 811. A plurality of guide rollers 813 are hinged on one side of the two sliding seats 812 close to each other.

[0045] It should be noted that the centering assembly 81 may include a bidirectional lead screw driven by a motor. By threadedly connecting the bidirectional lead screw with the two sliding seats 812, the two sliding seats 812 can be driven to move synchronously and in opposite directions. When the glass slide 33 is pushed out of the frame 31 by the pushing mechanism 7, the glass slide 33 is clamped by the centering assembly 81, and the guide rollers 813 are in contact with the edge of the glass slide 33 to reduce the friction force when pulling the glass slide 33 to move. By clamping the glass slide 33, the vertical center line of the glass slide 33 is kept consistent with the center line of the spacing of the track 61. Thus, when the glass slide 33 is adsorbed by the suction cup 634, the suction cup 634 can be adsorbed on the vertical center line of the glass slide 33. Furthermore, during the process of pulling the glass slide 33 to move, the problem that the glass slide 33 is prone to deflecting in the pulling process, resulting in the corners of the glass slide 33 coming into contact and colliding with the side of the track 61 and being damaged, can be solved.

[0046] In the above technical solution, the centering component 81 is provided to clamp the glass slide 33, so that the vertical center line of the glass slide 33 is aligned with the center line of the spacing of the track 61. However, for the relatively thin glass slide 33, its anti-mechanical shock ability is relatively weak and it is easily damaged by external forces. Therefore, when stored in the cassette 3, a rubber pad needs to be provided in the card slot 32 of the frame 31 to play a role in protecting the glass slide 33. However, at this time, when the glass slide 33 is pushed out by the pushing mechanism 7, since the rubber pad is made of a flexible material, when the glass slide 33 is pushed out, the glass slide 33 is easily affected by the frictional force between the rubber pad and the glass slide 33, resulting in the glass slide 33 not being able to slide smoothly, which easily causes the conveying component 22 to be displaced. The displacement usually includes lateral displacement and longitudinal displacement. The lateral displacement is the lateral swing angle of the glass slide 33, and the centering component 81 can clamp the glass slide 33 to ensure that this problem is solved. The longitudinal displacement is the vertical swing angle of the glass slide 33, and the vertical swing angle will cause the bottom of the glass slide 33 and the top of the suction cup 634 not to be in the same horizontal direction. The bottom of the glass slide 33 is in an inclined state. At this time, when the glass slide 33 is adsorbed by the suction cup 634, it is easy to have problems such as unstable adsorption or even inability to adsorb and fix the glass slide 33. At this time, the centering component 81 cannot solve the problem of the vertical angle of the glass slide 33. Therefore, the present invention also proposes a leveling component 82 to clamp the glass slide 33 up and down and adjust the glass slide 33 to a horizontal state. Specifically, refer to the attached drawings of the specification Figure 14 and Figure 15 , the adjusting mechanism 8 further includes a leveling component 82, and a set of leveling components 82 are provided on both sliding seats 812. The leveling component 82 includes two coaxially hinged hinge rods 821, and leveling rollers 822 are hinged at both ends of the hinge rods 821. Two sliders 823 are slidably provided on one side of the sliding seat 812. Elastic members three 824 are provided between the two sliders 823 and between the two hinge rods 821, and the two sliders 823 are abutted against the corresponding hinge rods 821. A fixed seat 825 is provided on the clamping component 811. Two inclined slots are opened in the fixed seat 825, and the sides facing away from each other of the two sliders 823 are provided with bevel edges. The bevel edges of the two sliders 823 are slidably abutted against the corresponding inclined slots.

[0047] It should be noted that the two hinged rods 821 are cross-arranged, and the elastic member three 824 is a spring. While the two slides 812 are driven by the centering component 81 to approach each other to clamp the glass slide 33, the slide 812 can drive the corresponding slider 823 to move synchronously, so that the two sliders 823 on the same side can move synchronously toward the direction close to the glass slide 33. At this time, through the cooperation of the inclined groove and the inclined edge, the two sliders 823 on the same side can be moved close to each other and squeeze the corresponding elastic member three 824. When the two sliders 823 move close to each other, they can squeeze the corresponding spring and drive the corresponding leveling roller 822 to move close to each other, so that it clamps the glass slide 33 up and down and levels the glass slide 33, thereby solving the problem that the glass slide 33 is prone to vertical displacement when being pushed out of the frame 31, which affects the adsorption, fixation and pulling of the glass slide 33.

[0048] In the above technical solution, since a rubber pad is required to protect the thinner glass slide 33, but since the rubber pad has a certain thickness and will be deformed due to the compression between the rubber pad and the glass slide 33, it is necessary to set the top surface height of the track 61 to be at the same height as the bottom surface of the card slot 32 to ensure that the glass slide 33 can be located on the track 61 when the glass slide 33 is pushed out, so as to avoid setting the top surface height of the track 61 too high, resulting in the glass slide 33 contacting the feeding end of the track 61 when the glass slide 33 is pushed out, thereby affecting the feeding. However, at this time, due to the provision of the centering component 81 and the leveling component 82, the glass slide 33 is straightened and leveled when the glass slide 33 is pushed out of the frame 31, but at this time, the glass slide 33 3 is higher than the top surface of the track 61. At this time, the bottom of the glass slide 33 is sucked by the suction cup 634. In the process of pulling the material, in order to improve the accuracy of picking up the material, the glass slide 33 is usually pushed out a little bit first, so that it is in a position where the suction cup 634 can directly suck it, and then sucked and pulled out by the suction cup 634, which can reduce the difficulty of positioning the suction cup 634, ensure that the suction cup 634 can accurately grasp the glass slide 33, and improve the accuracy of the picking up process. At the same time, in order to allow the glass slide 33 to change its position between the frame 31 and the track 61, the suction cup 634 is set to a flexible material. Then, in the process of sucking the glass slide 33 and pulling the glass slide 33 to move, when the glass slide 33 is completely separated from the centering component 81 and the leveling component 82, Figure 16As shown, at this time, the glass slide 33 will fall down on one side of the glass slide 33 under the action of gravity, and cause one side of the glass slide 33 to collide with the surface of the track 61, thereby damaging the glass slide 33 and affecting the processing of the glass slide 33. For this reason, the present invention also proposes a supporting mechanism 9 for supporting the glass slide 33 when the glass slide 33 is pulled out of the centering component 81 and the leveling component 82. For details, refer to the attached manual. Figures 16 to 18 A support mechanism 9 is provided on the track 61, and the support mechanism 9 includes a slide groove 91, and the slide groove 91 is opened on the track 61. A support block 92 is slidably provided in the slide groove 91, and an elastic member 93 is provided at the bottom end of the support block 92. A side bar 94 is fixedly provided on one side of the support block 92, and a stop block 95 is fixedly provided on the slide seat 812, and both the side bar 94 and the stop block 95 are provided with beveled edges, and the two beveled edges are movably abutted.

[0049] It should be noted that the supporting mechanism 9 includes two groups, wherein two stop blocks 95 are respectively arranged on corresponding slide seats 812, and the elastic member 93 is a spring. When the glass slide 33 is clamped by the centering component 81, the two side strips 94 can be squeezed and pushed upward by the two stop blocks 95, and the corresponding springs can be stretched so that the two supporting blocks 92 can be extended to support the glass slide 33. Therefore, when the glass slide 33 is completely separated from the centering component 81 and the leveling component 82, the glass slide 33 can be supported by the supporting blocks 92. At this time, the centering component 81 is driven to reset, so that the two slide seats 812 move away from each other and reset. That is, under the action of the two springs, the two supporting blocks 92 can be slowly moved downward and reset, thereby slowly lowering one side of the glass slide 33 to avoid the problem of collision and damage between the glass slide 33 and the surface of the track 61.

[0050] For further information, please refer to the attached manual. Figure 3 The magazine conveying and positioning mechanism 2 includes a positioning frame 21. The positioning frame 21 is a frame-type structure. The frame-type structure is conducive to preventing the frame 31 from tipping over. A conveying component 22 is arranged in the positioning frame 21. The conveying component 22 is used to dock with the loading and unloading conveying mechanism 4 to position and convey the frame 31 into the positioning frame 21. The positioning frame 21 is also provided with a guide strip 23, a magazine positioning component 24 and an in-place stop component 25. The guide strip 23 is used to guide the frame 31. The magazine positioning component 24 is used to fix the frame 31 in the positioning frame 21. The in-place stop component 25 is used to position and block the frame 31.

[0051] It should be noted that the first conveying component 22 is a conveying belt. The magazine positioning component 24 can include a cylinder, and a pressing plate is installed at the output end of the cylinder. The pressing plate is driven by the cylinder to press and fix the frame 31, so as to fix the frame 31. The in-place stop component 25 is a thin fiber optic sensor. After the thin fiber optic sensor senses that the frame 31 is in place, the operation of the conveying belt is stopped, and the frame 31 is clamped by the magazine positioning component 24.

[0052] Further, referring to the attached drawings of the specification Figure 5 , the loading and unloading conveying mechanism 4 includes a chassis 41. The chassis 41 is fixedly installed on the housing 1. A limiting frame 42 and a second conveying component 43 are arranged on the chassis 41. The limiting frame 42 is used to position and place the frame 31 on the second conveying component 43. The second conveying component 43 is used to dock with the first conveying component 22 and position and convey the frame 31 to the first conveying component 22.

[0053] It should be noted that the second conveying component 43 is a conveying belt. The second conveying component 43 is positioned and docked with the first conveying component 22 through the conveying belt to realize the positioning and conveying of the frame 31. By setting the limiting frame 42, when placing the frame 31, the loading position can be ensured within a certain range.

[0054] Further, referring to the attached drawings of the specification Figures 6 to 8 , the locking mechanism 5 includes a locking rod 51. The locking rod 51 is used to limit the displacement of the glass slide 33. When the locking rod 51 contacts the glass slide 33, the glass slide 33 is in a locked state. A pin hole is opened at the top of the frame 31. The top end of the locking rod 51 is slidably arranged in the pin hole, and a first elastic member 52 is arranged in the pin hole. The top end of the locking rod 51 is fixedly connected to the first elastic member 52, and the locking rod 51 can rotate in the pin hole. A limiting hole is opened at the bottom of the frame 31. When the bottom end of the locking rod 51 is inserted into the limiting hole, the locking rod 51 is in a locked state. A first cylinder 53 is fixedly installed on the housing 1. A motor 54 is installed at the output end of the first cylinder 53. A dial rod 56 is installed at the output end of the motor 54. Two fork-shaped rods 58 are installed at the bottom end of the dial rod 56. The distance between the two fork-shaped rods 58 is adapted to the locking rod 51. When the two fork-shaped rods 58 are stuck on the locking rod 51, both of the two fork-shaped rods 58 are in tangential contact with the locking rod 51. The fork-shaped rods 58 are arranged in a double-cylindrical shape and can be in tangential contact with the locking rod 51 when driving the locking rod 51 to rotate, which can avoid the jamming problem caused by the non-concentric rotation center. When the bottom end of the locking rod 51 slides out of the limiting hole, the locking rod 51 is unlocked. When the locking rod 51 rotates and separates from the glass slide 33, the locking rod 51 releases the locking of the glass slide 33.

[0055] It should be noted that when unlocking the glass slide 33, the lifting assembly 11 drives the cassette conveying and positioning mechanism 2 to move vertically upward, and then the first cylinder 53 drives the lever 56 to move downward, so that the lever 56 pushes the locking rod 51 to move downward, causing the locking rod 51 to be stuck between the two fork-shaped levers 58, and the bottom end of the locking rod 51 slides out of the limiting hole, releasing the locking of the locking rod 51. Then, by rotating the lever 56, the two fork-shaped levers 58 rotate the locking rod 51 to release the restriction on the glass slide 33, and then the glass slide 33 can be loaded and unloaded.

[0056] It should also be noted that by setting the locking mechanism 5, on the basis of setting the rubber pad, the glass slide 33 can be further fixed and protected, avoiding the problem that the frame 31 tilts during transportation, resulting in the glass slide 33 slipping off.

[0057] Further, referring to the attached drawings of the specification Figure 7 and Figure 8 , a rotating shaft 55 is installed at the output end of the motor 54. The lever 56 is slidably sleeved on the rotating shaft 55. An opening 551 is formed in the rotating shaft 55. A pin 57 is inserted through the rotating shaft 55 and the lever 56, and the pin 57 is located in the opening 551. An elastic member II 552 is provided between the rotating shaft 55 and the lever 56. The elastic member II 552 is used to control the downward pressure. The elastic member II 552 is used to enable the lever 56 and the rotating shaft 55 to rotate synchronously, and enable the lever 56 to slide axially along the rotating shaft 55. A proximity sensor 59 is installed in the lever 56, and the proximity sensor 59 is located between the two fork-shaped levers 58. The proximity sensor 59 is used to detect the positions of the locking rod 51 and the two fork-shaped levers 58.

[0058] It should be noted that by setting the opening 551, the elastic member II 552 and the pin 57, the elastic member II 552 is a spring. Through the cooperation of the opening 551 and the elastic member II 552, a structure that can rotate synchronously and slide axially is formed. And through the spring, the downward pressure can be controlled so as not to exceed the spring force. And through the proximity sensor 59, it can be detected whether the locking rod 51 is between the two fork-shaped levers 58.

[0059] Further, referring to the attached drawings of the specification Figures 9 to 11, the blanking mechanism 6 further includes a first blanking drive assembly 62. The first blanking drive assembly 62 is used to drive the push-pull assembly 63 to linearly move along the trajectory of the track 61. The spacing at the feeding end of the track 61 is greater than that at the discharging end, and the feeding end of the track 61 is trumpet-shaped. A measuring sensor 64 is further provided on the push-pull assembly 63. The measuring sensor 64 is used to detect the front and back sides of the glass carrier 33. A second drive assembly 65 is also provided on the housing 1. The track 61 is installed at the output end of the second drive assembly 65. The second drive assembly 65 is used to drive the track 61 to move and switch positions. The suction cup 634 is flexibly connected to the glass carrier 33, so that when the suction cup 634 adsorbs the glass carrier 33, relative swing can occur between the suction cup 634 and the glass carrier 33. The push-pull assembly 63 further includes a connecting block 631. The connecting block 631 is arranged at the output end of the first blanking drive assembly 62. A second cylinder 632 is fixedly arranged on the connecting block 631. The push-pull block 633 is installed at the output end of the second cylinder 632, and the suction cup 634 is installed on the push-pull block 633.

[0060] It should be noted that while slowly lowering one side of the glass carrier 33, the second cylinder 632 can also be used to drive the other side of the glass carrier 33 to slowly move downward, so that the glass carrier 33 can be slowly and smoothly placed on the track 61, and then the glass carrier 33 is dragged to move on the track 61. By making the feeding section of the track 61 wider and adjustable to be trumpet-shaped, it is convenient to dock with the frame 31, and the spacing of the discharging section is set smaller, which can facilitate the control of the position accuracy of the glass carrier 33. Both the first blanking drive assembly 62 and the second drive assembly 65 are linear drive structures, and structures such as cylinders or synchronous belt transmissions can be adopted to achieve their linear motion.

[0061] Further, referring to the attached drawings of the specification Figure 12 , the pusher mechanism 7 includes a third cylinder 71. The third cylinder 71 is installed at the bottom of the chassis 41. The output end of the third cylinder 71 is installed with a pusher block 72. During blanking, the third cylinder 71 drives the pusher block 72 to push a part of the glass carrier 33 to extend out of the frame 31, so that the suction cup 634 adsorbs the bottom of the extended part of the glass carrier 33, and the first blanking drive assembly 62 is used to drive the push-pull assembly 63 to linearly move to pull the glass carrier 33 out of the frame 31.

[0062] It should be noted that the third cylinder 71 is used to drive the pusher block 72 to linearly move, so that it can push the glass carrier 33 to move out of the frame 31. During the blanking process, in order to improve the accuracy of material taking, the glass carrier 33 is first pushed out by a certain length so that it is in a position where the suction cup 634 can directly suck it, and then it is sucked out by the suction cup 634, which can reduce the positioning difficulty of the suction cup 634, ensure that the suction cup 634 can accurately grasp the glass carrier 33, and improve the accuracy of the material taking process.

[0063] The above embodiments only illustrate several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
