[0057] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] like Figure 1 - Figure 6 As shown, the carrier lifting device provided in the embodiment of the present invention includes: a first conveying assembly, a second conveying assembly and a lifting support device.

[0059] The first conveying assembly and the second conveying assembly are arranged at intervals, and the lifting support device is located between the first conveying assembly and the second conveying assembly; the first conveying assembly includes a first conveyor belt 110, and the second conveyor belt 210 is used to support the left and right edges of the carrier plate.

[0060] The lifting support device includes a lifting mechanism 10, a support platform 20 and a vacuum mechanism. The lifting mechanism 10 is connected to the support platform 20, and the lifting mechanism 10 is used to drive the support platform 20 to lift and lower. The lifting mechanism 10 may include a telescopic cylinder, such as a cylinder. The support platform 20 is used to support the carrier, and the support surface of the support platform 20 has a plurality of vacuum suction holes. The vacuum mechanism is used to communicate with the vacuum suction holes so that the carrier can be adsorbed on the support surface of the support platform 20.

[0061] The operating principle of the device is as follows: initially, the support surface of the support platform 20 is located below the top surface of the first conveyor belt 110 and the second conveyor belt 210, and the first conveyor belt 110 of the first conveyor assembly and the second conveyor belt 210 of the second conveyor assembly arranged at intervals support the carrier and convey the carrier forward. When the carrier moves to the bottom of the detection mechanism, that is, directly above the support platform 20, the support platform 20 can be driven by the lifting mechanism 10 to rise upward and support the carrier on the first conveyor belt 110 and the second conveyor belt 210, and the support platform 20 can completely lift the carrier to a preset height. Then the vacuum mechanism is started, and negative pressure is generated in the vacuum suction hole on the support platform 20, and the back of the transparent adhesive film of the carrier is adsorbed on the support platform 20, and the photosensitive chip originally attached to the front of the transparent adhesive film moves with the transparent adhesive film and adheres to the upper surface of the support platform 20. By using the support platform 20 to support the carrier and using negative pressure to make the transparent adhesive film on the carrier adhere to the upper surface of the support platform 20, multiple photosensitive chips on the carrier can be placed at the same height, which is convenient for the focusing of the detection mechanism during image acquisition and avoids abnormal detection results due to blurred imaging of individual photosensitive chips, thereby improving detection accuracy.

[0062] The carrier lifting device further includes a first synchronization shaft and a first driving mechanism 400 .

[0063] The first conveying assembly further includes a first roller 120 and a first bracket 130. The first roller 120 is plural in number, and the first rollers 120 are rotatably connected to the first bracket 130. The first conveyor belt 110 is wound around the first roller 120. In this embodiment, the first roller 120 may be two in number, and the first conveyor belt 110 is wound around the first roller 120.

[0064] The second conveying assembly further includes a second roller 220 and a second bracket 230, wherein the number of the second rollers 220 is multiple, and the multiple second rollers 220 are rotatably connected to the second bracket 230, and the second conveyor belt 210 is wound around the second rollers 220. In this embodiment, the number of the second rollers 220 can be two, and the second conveyor belt 210 is wound around the second rollers 220.

[0065] The number of the first rollers 120 , the second rollers 220 and the first synchronization shaft is the same, for example, two, and they correspond one to one.

[0066] The first synchronization shaft includes an inner shaft 310 and an outer shaft 320, the inner shaft 310 includes a first end and a second end, the outer shaft 320 includes a third end and a fourth end, and a first sliding hole is provided on the third end of the outer shaft 320, and the first sliding hole extends along the axial direction of the outer shaft 320. The second end of the inner shaft 310 is slidably connected in the first sliding hole so that the inner shaft 310 can slide along the axial direction of the outer shaft 320.

[0067] The inner shaft 310 and the outer shaft 320 are provided with a first limiting structure, and the first limiting structure is used to make the inner shaft 310 and the outer shaft 320 have the same movement state in the circumferential direction; that is, the inner shaft 310 can slide along the axial direction of the outer shaft 320, but the inner shaft 310 cannot rotate relative to the outer shaft 320 and around the axis of the outer shaft 320.

[0068] The first end of the inner shaft 310 is coaxially connected to the first roller 120, and the fourth end of the outer shaft 320 is coaxially connected to the second roller 220, so that the first conveyor belt 110, the first roller 120, the first synchronization shaft, the second roller 220 and the second conveyor belt 210 have the same rotation state.

[0069] The first driving mechanism 400 includes a motor and a first active roller. The motor drives the first active roller to rotate. The first active roller is connected to the first conveyor belt 110 or the second conveyor belt 210 to drive the first conveyor belt 110 or the second conveyor belt 210 to rotate.

[0070] The first roller 120 and the second roller 220 are connected via a first synchronous shaft, and the first synchronous shaft includes an inner shaft 310 and an outer shaft 320 that can slide against each other, so that by sliding the inner shaft 310 and the outer shaft 320, the distance between the first roller 120 and the second roller 220 can be changed, that is, the distance between the first conveyor belt 110 and the second conveyor belt 210 is changed. The first driving mechanism 400 can drive the first conveyor belt 110 or the second conveyor belt 210 to rotate, because the inner shaft 310 and the outer shaft 320 cannot rotate relative to each other, so the first conveyor belt 110 and the second conveyor belt 210 can have the same rotation state through the first synchronous shaft, so that the conveyor belt can adapt to carriers of different widths, and the conveyor belt has universality.

[0071] The first limiting structure includes a limiting pin 330 disposed on the side wall of the inner shaft 310 and protruding outward, and a limiting groove disposed on the side wall of the outer shaft 320 and parallel to the axial direction thereof, wherein the limiting pin 330 is slidably connected in the limiting groove. One end of the limiting groove can be communicated with the third end face of the outer shaft 320, and the number of the limiting pin 330 and the limiting groove can be multiple, and the limiting groove is disposed along the axial direction, and the side wall of the limiting groove can prevent the limiting pin 330 on the inner shaft 310 from rotating.

[0072] The carrier lifting device also includes a base plate 510, the second bracket 230 is fixedly connected to the base plate 510, and the first bracket 130 is slidably connected to the base plate 510, so as to facilitate the adjustment of the distance between the first conveyor belt 110 on the first bracket 130 and the second conveyor belt 210 on the second bracket 230.

[0073] The base plate 510 is provided with a first slide rail 521 and a second slide rail 522, both of which extend along the width direction of the device; the first slide rail 521 is provided with a first slider 531, and the second slide rail 522 is provided with a second slider 532; the first bracket 130 is connected to the first slider 531, and the lifting support device is connected to the second slider 532.

[0074] The first bracket 130 is provided with a first screw hole, the lifting support device is provided with a second screw hole, the second bracket 230 is rotatably connected with an adjusting bolt 600, the side wall of the adjusting bolt 600 is provided with a first external thread section 610 and a second external thread section 620, the first external thread section 610 is used for threading connection with the first screw hole, the second external thread section 620 is used for threading connection with the second screw hole, and the pitch of the first external thread section 610 is twice the pitch of the second external thread section 620. By rotating the adjusting bolt 600, the first bracket 130 and the lifting support device can move toward the second bracket 230 together, or move away from the second bracket 230 together, and because the pitches of the first external thread section 610 and the second external thread section 620 on the adjusting bolt 600 are designed by calculation, after the adjusting bolt 600 is rotated by an angle, the lifting support device can always be in the middle position between the first bracket 130 and the second bracket 230 when the first bracket 130 is away from or close to the second bracket 230. For example, in the initial position, the distance between the lifting support device and the first bracket 130 and the second bracket 230 is 0, and then by rotating the adjusting bolt 600, the first bracket 130 moves 2 cm away from or close to the second bracket 230, and the lifting support device moves 1 cm away from or close to the second bracket 230. At this time, the distance between the lifting support device and the first bracket 130 and the second bracket 230 is 1 cm.

[0075] The lifting support device also includes a stopper 710 and a second driving mechanism, the stopper 710 is connected to the second driving mechanism, and the second driving mechanism is used to drive the stopper 710 to move to the conveying path of the carrier plate, or move away from the conveying path of the carrier plate.

[0076] By changing the state of the stopper 710, the stopper 710 can be blocked on the moving path of the carrier, thereby preventing the carrier from continuing to move, and facilitating the carrier to stay directly above the support platform 20. Specifically, the second driving mechanism includes a cylinder, one end of the stopper 710 forms a stopper for blocking the carrier, and the other end is connected to the movable end of the cylinder, and the middle part of the stopper 710 is rotatably connected to the support platform 20 via a rotating shaft. By driving one end of the stopper 710 through the extension and contraction of the cylinder, the stopper 710 can swing, thereby moving the stopper 710 to the conveying path of the carrier, or moving away from the conveying path of the carrier.

[0077] like Figure 6 - Fig.11 As shown, the plate conveyor belt inspection platform provided by the embodiment of the present invention includes the above-mentioned plate lifting device. Because the plate conveyor belt inspection platform provided by the embodiment of the present invention uses the above-mentioned plate lifting device, the plate conveyor belt inspection platform provided by the embodiment of the present invention also has the advantages of the plate lifting device.

[0078] The carrier conveyor belt inspection station also includes a carrier conveyor belt push-out device 800 and a translation device, wherein the carrier conveyor belt push-out device 800 is fixed on the translation device, and the translation device is used to drive the carrier conveyor belt push-out device 800 to move to the extension line of the transmission path of the carrier lifting device or move out from the extension line of the transmission path of the carrier lifting device. When the photosensitive chip on the carrier is inspected, the support platform 20 descends, the carrier returns to the first conveyor belt 110 and the second conveyor belt 210, and the carrier continues to move forward to the carrier conveyor belt push-out device 800. If no problem is detected in the photosensitive chip, the carrier will continue to be transported forward to the designated area. If there is a problem with the photosensitive chip, the translation device will drive the entire carrier conveyor belt push-out device 800 to translate, so that the end of the carrier conveyor belt push-out device 800 that was originally connected to the carrier lifting device is separated from the carrier lifting device, and the carrier conveyor belt push-out device 800 pushes the carrier in the opposite direction, pushes the carrier from the end that enters the carrier conveyor belt push-out device 800, and pushes it to the designated area. After completing the push-out of the unqualified carrier, the translation device drives the carrier conveyor belt push-out device 800 back to the position aligned with the carrier lifting device to receive the next carrier again.

[0079] The translation device is not shown, and the translation device can be a common driving platform, and the driving direction is perpendicular to the transportation direction, that is, Figure 6 In the direction of the arrow.

[0080] Specifically, the carrier conveyor belt ejection device 800 includes: a first transmission belt mechanism 810, a second transmission belt mechanism 820 and an ejection mechanism. The first transmission belt mechanism 810 and the second transmission belt mechanism 820 are arranged in parallel and at intervals. The first transmission belt 941 on the first transmission mechanism and the first transmission belt 941 on the second transmission mechanism jointly support the carrier, and realize the forward or backward movement of the carrier by forward or reverse rotation. However, the first transmission belt mechanism 810 and the second transmission belt mechanism 820 alone cannot completely transport the carrier to the position. When the carrier is just separated from the first transmission belt mechanism 810 and the second transmission belt mechanism 820, the carrier cannot continue to move, and thus cannot completely enter the silo. Therefore, an ejection mechanism is required to assist in pushing the carrier completely into the silo.

[0081] The ejection mechanism includes a support frame, a connecting plate 832, a roller 833, a first track 834, a first sliding member 835, a second sliding member 836, a first driving module, a return spring 837 and a pusher 838. The pusher 838 is located between the first transmission belt mechanism 810 and the second transmission belt mechanism 820.

[0082] The first track 834 is mounted on the support frame, and the first sliding member 835 is slidably connected to the first track 834. The first track 834 extends along the transmission direction, which is the front-back direction in this embodiment. The second sliding member 836 is slidably connected to the first sliding member 835, and the second sliding member 836 can move vertically relative to the first sliding member 835. The connecting plate 832 can be "L" shaped, which includes a first part and a second part connected vertically, the second part is connected to the second sliding member 836, and the first part is connected to the pusher 838, and the upper surface of the pusher 838 has a push protrusion 8381 protruding upward, and the push protrusion 8381 is used to push the carrier. One end of the reset spring 837 is connected to the connecting plate 832, and the other end is connected to the first sliding member 835. The support frame is provided with a support surface extending along the transmission direction, and the support surface has a groove 831 that is vertically and downwardly concave, and the inner wall of the groove 831 is smoothly transitioned with the support surface, so that the roller 833 can move back and forth between the support surface and the groove 831. The roller 833 is rollingly connected to the first part, and the support surface supports the roller 833. The first driving module is used to drive the first sliding member 835 to move along the transmission direction, so that when the roller 833 is located in the groove 831, the pushing protrusion 8381 is lower than the supporting plane formed by the first transmission belt mechanism 810 and the second transmission belt mechanism 820, or the pushing protrusion 8381 is flush with the supporting plane formed by the first transmission belt mechanism 810 and the second transmission belt mechanism 820, and when the roller 833 is located on the support surface, the pushing protrusion 8381 is higher than the supporting plane formed by the first transmission belt mechanism 810 and the second transmission belt mechanism 820.

[0083] In the initial state, the roller 833 on the connecting plate 832 is located in the groove 831, and the pushing protrusion 8381 on the pushing member 838 will not affect the movement of the carrier on the first transmission belt mechanism 810 and the second transmission belt mechanism 820. When the carrier supported by the first transmission belt mechanism 810 and the second transmission belt mechanism 820 completes the inspection, assuming that the inspection result is unqualified, the first driving module is started, and the first driving module can drive the first sliding member 835 to move to the left, and then the second sliding member 836, the connecting plate 832, and the pushing member 838 all move to the left. During the leftward movement, the roller 833 rolls out of the groove 831 and moves to the supporting surface, the second sliding member 836 moves upward relative to the first sliding member 835, the reset spring 837 is stretched, and the pushing protrusion 8381 on the pushing member 838 exceeds the height of the carrier, and the pushing protrusion 8381 can push the carrier to move to the left together, and the pushing member 838 can completely transport the carrier from the first transmission belt mechanism 810 and the second transmission belt mechanism 820. After one transport is completed, the first driving module drives the first sliding member 835 to move in the reverse direction, so that the roller 833 on the connecting plate 832 rolls into the groove 831 again, that is, returns to the initial position. During the entire sorting and pushing process, only one power source is used to complete the horizontal and vertical movement of the pusher 838, which greatly reduces the device downtime caused by power source failure, and at the same time, can also reduce the production cost of the device.

[0084] The first transmission belt mechanism 810 includes a first transmission belt 941 and a first pulley 942, the number of the first pulleys 942 is multiple, and the first transmission belt 941 is wound around the first pulley 942; the second transmission belt mechanism 820 includes a second transmission belt 951 and a second pulley 952, the number of the second pulleys 952 is multiple, and the second transmission belt 951 is wound around the second pulley 952; the first pulley 942 and the second pulley 952 are connected by a second synchronous shaft, the second synchronous shaft includes a first shaft and a second shaft, the first shaft includes a first end and a second end, the second shaft includes a third end and a fourth end, the third end of the second shaft is provided with a sliding hole, The second end of the first shaft is slidably connected in the sliding hole so that the first shaft can slide along the axial direction of the second shaft, and a second limiting structure is provided on the first shaft and the second shaft, and the second limiting structure is used to make the first shaft and the second shaft have the same motion state in the circumferential direction; the first end of the first shaft is coaxially connected to the first pulley 942, and the fourth end of the second shaft is coaxially connected to the second pulley 952; the carrier conveyor belt pushing device 800 includes a second driving module, and the second driving module includes a driving wheel, and the driving wheel is connected to the first transmission belt 941 or the second transmission belt 951, and is used to drive the first transmission belt 941 or the second transmission belt 951 to rotate.

[0085] The first transmission belt mechanism 810 includes a first transmission belt 941, a first pulley 942 and a first assembly frame 943. The number of the first pulleys 942 is multiple, and the multiple first pulleys 942 are rotatably connected to the first assembly frame 943. In this embodiment, the number of the first pulleys 942 can be two, and the first transmission belt 941 is wound around the first pulley 942. The second transmission belt mechanism 820 includes a second transmission belt 951, a second pulley 952 and a second assembly frame 953. The number of the second pulleys 952 is multiple, and the multiple second pulleys 952 are rotatably connected to the second assembly frame 953.

[0086] In this embodiment, the number of the second pulleys 952 can be two, and the second transmission belt 951 is wound around the second pulley 952. The second synchronous shaft includes a first shaft and a second shaft, the first shaft includes a first end and a second end, the second shaft includes a third end and a fourth end, the third end of the second shaft is provided with a sliding hole, the sliding hole extends along the axial direction of the second shaft, and the second end of the first shaft is slidably connected in the sliding hole, so that the first shaft can slide along the axial direction of the second shaft. And the first shaft and the second shaft are provided with a second limiting structure, and the second limiting structure is used to make the first shaft and the second shaft have the same motion state in the circumferential direction. That is to say, the first shaft can slide along the axial direction of the second shaft, but the first shaft cannot rotate relative to the second shaft and around the axis of the second shaft. The first end of the first shaft is coaxially connected to the first pulley 942, and the fourth end of the second shaft is coaxially connected to the second pulley 952, so that the first transmission belt 941, the first pulley 942, the synchronous shaft, the second pulley 952 and the second transmission belt 951 have the same rotation state.

[0087] The second driving module includes a motor and a driving wheel. The motor drives the driving wheel to rotate. The driving wheel is connected to the first transmission belt 941 or the second transmission belt 951 to drive the first transmission belt 941 or the second transmission belt 951 to rotate. The first pulley 942 and the second pulley 952 are connected by a second synchronous shaft, and the second synchronous shaft includes a first shaft and a second shaft that can slide against each other. Therefore, by sliding the first shaft and the second shaft, the distance between the first pulley 942 and the second pulley 952 can be changed, that is, the distance between the first transmission belt 941 and the second transmission belt 951 is changed. The second driving module can drive the first transmission belt 941 or the second transmission belt 951 to rotate. Because the first shaft and the second shaft cannot rotate relative to each other, the first transmission belt 941 and the second transmission belt 951 can have the same rotation state through the second synchronous shaft, so that the conveyor belt can adapt to carriers of different widths, and the conveyor belt has universality.

[0088] The principle of the width-adjustable conveying mechanism formed by the first conveying assembly, the second conveying assembly and the first synchronous shaft is the same as the width adjustment principle of the transmission mechanism formed by the first transmission belt mechanism 810, the second transmission belt 951 and the second synchronous shaft.

[0089] The first driving module includes a motor, a third pulley 8391, and a third conveyor belt 8392. The conveyor belt is wound around the third pulley 8391. The motor is connected to the third pulley 8391. The first sliding member 835 is connected to the third conveyor belt 8392. The third pulley 8391 is driven by the motor to rotate the third conveyor belt 8392. A part of the third conveyor belt 8392 moves linearly, thereby driving the first sliding member 835 to move linearly.
