Abstract
Description
Technical Field
[0001] This utility model relates to the field of substrate processing and transportation technology, and in particular to a substrate conveying device based on automatic alarm triggering of a pallet. Background Technology
[0002] In automated production lines, especially in the field of flat material processing, ensuring the smooth and continuous transport of rigid planar substrates is crucial. The core working principle of this device is to transport the substrate through a drive unit and a support structure, and to use sensors to monitor the flow status of the substrate in real time at critical path points. Once the substrate is detected to be stuck for more than a preset time due to misalignment, stacking, or obstacles, the alarm system is automatically triggered to alert the operator to handle the fault.
[0003] Most existing substrate conveying devices based on automatic alarm triggering of pallets use optical sensors for monitoring, which cannot adapt to various harsh environments. Moreover, during monitoring, staff must be ready to deal with emergencies at any time and cannot leave. During long-term operation, substrate stacking and skewing are prone to occur, which can cause pallet jamming and damage to the substrate itself, reducing work efficiency and failing to guarantee product quality.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] The substrate conveying device disclosed in this utility model is based on automatic alarm triggering of the pallet. It is mainly used in scenarios where existing substrate conveying devices based on pallet alarms rely on optical sensors for monitoring, have poor environmental adaptability, require dedicated personnel to operate, and are prone to damage to the substrate due to pallet stacking or tilting during long-term operation, thus affecting efficiency and product quality.
[0021] Reference Figure 1A substrate conveying device based on automatic alarm triggering of pallet trays includes: a support 1, with fixed brackets 3 fixedly connected to both sides of the support 1, and a common inlet port 2 fixedly connected to the same end of the two fixed brackets 3, the lower end of the inlet port 2 being fixedly connected to the upper side of the support 1; an outlet port 5 fixedly connected to the end of the two fixed brackets 3 away from the inlet port 2, the lower end of the outlet port 5 being fixedly connected to the upper side of the support 1; a monitoring and alarm component 4 disposed on the upper side of the two fixed brackets 3, the monitoring and alarm component 4 being used to monitor whether the substrate is palletized during transportation, and triggering an alarm when the substrate is palletized; and a shaking component 6 disposed on the upper side of the support 1, the shaking component 6 being used to shake apart the substrates palletized, thereby reducing the degree of substrate palletization.
[0022] Reference Figures 1-4 In a preferred embodiment, the monitoring alarm component 4 includes: two limiting fixing blocks 406, which are respectively fixedly connected to the opposite outer sides of two fixing brackets 3, and the two limiting fixing blocks 406 are located on the same horizontal line. Each of the two limiting fixing blocks 406 has an L-shaped fixing bracket 405 fixed inside it by bolts; and two telescopic springs 401, one end of which is respectively fixedly connected to the upper side of the corresponding two L-shaped fixing brackets 405, and the other end of which is respectively fixedly connected to a movable... Block 402, two movable blocks 402 slide on the upper side of the corresponding L-shaped fixed frame 405 respectively; connecting rod 409, two connecting rods 409 are slidably connected to the movable slots opened on the upper side of the corresponding L-shaped fixed frame 405 respectively, one end of the two connecting rods 409 is fixedly connected to the lower side of the corresponding movable block 402 respectively, and the other end of the two connecting rods 409 is fixedly connected to the fixed block 403 respectively. The two fixed blocks 403 have a rotating hole on the opposite side, and the same rotating rod 407 is connected inside the rotating hole through a bearing.
[0023] In this scheme, the monitoring and alarm component 4 further includes: a rotating monitoring plate 404, fixedly connected to the outer wall of the rotating rod 407; two torsion springs 408, which are equally spaced and sleeved on the outer wall of the rotating rod 407, with the two torsion springs 408 located on both sides of the rotating monitoring plate 404, one end of each torsion spring 408 being fixedly connected to both sides of the rotating monitoring plate 404, and the other end being fixedly connected to the corresponding fixing block 403; and a connecting plate 413, fixedly connected to one of the fixing blocks 403 on the side away from the rotating monitoring plate 404, with a large gear 412 provided on the side of the connecting plate 413 away from the fixing block 403, and the large gear 412 being fixedly connected to the outer wall of the end of the rotating rod 407 located outside the connecting plate 413. A trigger shaft 414 is connected to the inside of the end of the connecting plate 413 away from the large gear 412 via a bearing. A small gear 411 is fixedly connected to the outer wall of the end of the trigger shaft 414 on the same side as the large gear 412. The large gear 412 and the small gear 411 mesh with each other. A sensing chamber 415 is fixedly connected to the side of the connecting plate 413 away from the small gear 411. The end of the trigger shaft 414 away from the small gear 411 is located inside the sensing chamber 415. Under normal circumstances, the trigger block set on the trigger shaft 414 is always in contact with the initial sensing block inside the sensing chamber 415. An alarm 410 is set on the side of the connecting plate 413 away from the small gear 411. The alarm 410 is located between the sensing chamber 415 and one of the fixed blocks 403.
[0024] When using the substrate conveying device with automatic alarm triggering based on the plate, since the limit fixing block 406 and the L-shaped fixing frame 405 are connected by bolts, the operator can adjust the height between the rotating monitoring plate 404 in the monitoring alarm component 4 and the conveyor belt 10 to adapt to the height of different substrates. The amplification effect is generated by the large gear 412 and the small gear 411, so that the degree and severity of substrate plate jamming can be monitored more accurately.
[0025] Reference Figure 1 , Figure 5 and Figure 6 In a preferred embodiment, the swaying component 6 includes: a sliding rail 602, two sliding rails 602 respectively disposed on the upper sides of both ends of the support 1, a buffer long plate 601 and a buffer short plate 603 respectively fixedly connected at equal intervals on the upper side of the support 1, one end of a plurality of buffer springs 604 fixedly connected at equal intervals on one side of the buffer long plate 601, and one end of two buffer springs 604 fixedly connected at equal intervals on the side of the buffer short plate 603 opposite to the buffer long plate 601.
[0026] In this scheme, the shaking assembly 6 further includes: a toggle shaft 606, two toggle shafts 606 are connected at equal intervals to the two rotating holes opened on the upper side of the support 1 near the buffer short plate 603 through bearings, the two toggle shafts 606 are respectively located on both sides of the buffer short plate 603, and the same transmission belt 608 is provided on the outer wall of the end of the two toggle shafts 606 located on the lower side of the support 1; a toggle plate 605, two toggle plates 605 are respectively fixedly connected to the upper outer wall of the corresponding toggle shaft 606; a rotary motor 607, fixedly connected to the lower side of the support 1, the drive end of the rotary motor 607 is connected to the end of one of the toggle shafts 606 located on the lower side of the support 1 through a coupling.
[0027] When using the substrate conveying device with automatic alarm triggering based on the pallet, the rotation of the actuating plate 605 continuously actuates the conveyor support 11, causing it to move back and forth along the two sliding tracks 602. Under the action of multiple buffer springs 604 and the two actuating plates 605 that continuously actuate the conveyor support 11, the substrates stacked on the conveyor belt 10 can be separated from each other by the inertia generated by the shaking of the conveyor belt 10, thereby helping to prevent the substrates from being stuck on the pallet.
[0028] Reference Figure 1 , Figure 5 and Figure 6 In a preferred embodiment, a conveying bracket 11 is provided on the upper side of the support 1. Fixed grooves are formed on the lower sides of both ends of the conveying bracket 11. Multiple rollers 14 are connected at equal intervals within the two fixed grooves via bearings. The multiple rollers 14 located on the lower sides of both ends of the conveying bracket 11 slide on corresponding sliding tracks 602. The conveying bracket 11 can move back and forth along the two sliding tracks 602 under the action of the multiple rollers 14. The two sides of the conveying bracket 11 are fixedly connected to the other ends of the buffer springs 604 on the buffer long plate 601 and buffer short plate 603, respectively. Next, the inner wall of the conveyor bracket 11 has equally spaced circular holes on opposite sides. The two circular holes are connected to a rotating shaft 13 through bearings. The outer walls of the two rotating shafts 13 are provided with the same conveyor belt 10. A drive motor 12 is fixedly connected to one side of the conveyor bracket 11. The drive end of the drive motor 12 is connected to one end of one of the rotating shafts 13 through a coupling. U-shaped frames 7 are fixedly connected to the upper sides of both ends of the conveyor bracket 11. Multiple rollers 8 are connected at equal intervals through bearings on the inner walls of the two U-shaped frames 7. The outer walls of the multiple rollers 8 are provided with the same protective belt 9.
[0029] When using the substrate conveying device that automatically triggers alarms based on pallets, multiple rollers 8 are installed inside the U-shaped frame 7 fixed on both sides of the conveyor belt 10. The protective belts 9 installed on the outer walls of the multiple rollers 8 can protect the stacked pallet substrates that collide with the swaying component 6 due to the inertial force generated by the swaying component 6 without affecting the transport of the substrates. The elastic collision prevents the substrates from being worn.
[0030] Working Principle: When using the substrate conveying device with automatic alarm triggering based on pallets, the operator first conveys the stacked substrates onto the conveyor belt 10 through the inlet port 2. Simultaneously, the drive motor 12 is turned on, causing the conveyor belt 10 to rotate and transport the substrates. Since the limiting fixing block 406 and the L-shaped fixing frame 405 are connected by bolts, the operator can adjust the height between the rotating monitoring plate 404 in the monitoring and alarm component 4 and the conveyor belt 10 to accommodate different substrate heights. During normal substrate transport, the stacked substrates pass through the monitoring and alarm component 4. Because the rotating monitoring plate 404 always maintains a certain preset small gap distance with the substrate, it ensures that the substrates will not come into contact with it during normal transport, thus preventing any impact. The substrates then pass through the monitoring and alarm component 4... The substrate is sent to the next processing area from the discharge port 5. When the substrate is stacked and jammed during transportation, the stacking of the substrate increases the height of the stacked substrates when passing the monitoring alarm component 4, exceeding the height allowed for normal passage of the rotating monitoring plate 404. This causes pressure on the rotating monitoring plate 404. Under the pressure of the stacked substrates, the rotating monitoring plate 404 overcomes the elastic force of the two torsion springs 408 and deflects clockwise by a certain distance. As the rotating monitoring plate 404 deflects, the rotating rod 407 drives the large gear 412 to rotate clockwise. Since the small gear 411 meshes with the large gear 412, the small gear 411 drives the trigger shaft 414 to rotate counterclockwise under the action of the large gear 412. During this process, the transmission... The amplification effect produced by the action of the large gear 412 and the small gear 411 allows for more precise monitoring of the degree and severity of substrate jamming. When the trigger block on the trigger shaft 414 disengages from the initial sensing block inside the sensing chamber 415, the alarm 410 is not triggered immediately. Instead, the rotary motor 607 is activated, causing the two actuating shafts 606 to continuously rotate the actuating plate 605 via the transmission belt 608. As the actuating plate 605 rotates, it continuously actuates the conveyor bracket 11, causing it to move back and forth along the two sliding tracks 602. Under the action of multiple buffer springs 604 and the two actuating plates 605 continuously actuating the conveyor bracket 11, the substrates stacked on the conveyor belt 10 can be shaken and produced... Under the inertia of the substrate, they separate from each other, thereby helping to prevent the substrate from stacking and jamming. When the height of the stacked substrate exceeds the maximum allowable limit of the monitoring and alarm component 4 during transportation, the shaking component 6 cannot handle the excessively stacked substrate, causing the rotating monitoring plate 404 in the monitoring and alarm component 4 to be continuously squeezed and deflected until the trigger block on the trigger shaft 414 contacts the final sensing block, triggering the alarm 410. After hearing or seeing the alarm, the staff quickly rushes to the scene to find the location of the stacked substrate and manually removes it. Once the stacked substrate is removed, the rotating monitoring plate 404 is no longer pushed by the substrate and is reset under the action of the torsion spring 408. After the staff confirms that everything is correct, the production line can be restarted to restore production.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
