Description

Technical Field

[0001] This application relates to the technical field of substrate production equipment, and in particular to a feeding device for substrate handling equipment. Background Technology

[0002] LEDs and COBs are currently the most widely used light sources. During production, they need to be integrated onto substrates for transfer and related production testing. With increasing automation, the feeding and loading of substrates must also be matched to the operation of automated systems. (Refer to...) Figure 1 Generally, the substrate is supported by a material frame 19. Each material frame 19 has a partition layer for multiple substrates to be stacked and spaced apart. The opposite sides of the material frame 19 are connected. When the material frame 19 moves to the inlet side of the operating equipment, each substrate is pushed into the operating equipment by the pushing mechanism for related operations.

[0003] Currently, substrate feeding and conveying devices are typically vertically arranged, with several material frames 19 vertically positioned within the device. Through vertical conveying, each substrate in the material frames 19 is aligned horizontally with the inlet of the operating equipment, thus achieving the substrate feeding and conveying process. However, the vertical conveying length of the material frames 19 is limited, restricting the number of frames that can be placed in the feeding and conveying device. In actual production, a maximum of three material frames 19 can be placed in the feeding and conveying device at a time. After all three material frames 19 have been fed, the feeding and conveying device needs to vertically return the empty material frames 19 before performing a material replacement operation. This replacement process involves the operator removing the empty material frames 19 from the feeding and conveying device and then placing the full material frames 19 back into it. This replacement process prevents substrate loading, resulting in intermittent loading and cumbersome material frame replacement operations, significantly reducing the efficiency of substrate marking or inspection. This problem urgently needs improvement. Summary of the Invention

[0004] In order to improve the feeding efficiency of substrates, this application provides a feeding device for substrate handling equipment.

[0005] This application provides a feeding device for a substrate handling equipment, which adopts the following technical solution:

[0006] A feeding device for a substrate handling equipment, which is provided on one side of the substrate inlet of the handling equipment, includes a horizontally arranged conveyor frame, on which a horizontal conveying mechanism, a lifting mechanism and a pushing mechanism are provided;

[0007] The horizontal conveying mechanism is horizontally arranged on one side of the substrate feed port of the operating equipment for horizontal conveying of the material frame. The horizontal conveying mechanism includes a first conveying section and a second conveying section. The lifting mechanism is arranged between the first conveying section and the second conveying section and is located at the substrate feed port to drive the material frame to move vertically up and down.

[0008] The pushing mechanism is located on the side of the lifting mechanism away from the operating device. The pushing mechanism has a pushing plane, which is directly opposite the substrate feed port of the operating device in the horizontal direction. When the material frame moves to the lifting mechanism, the pushing mechanism pushes the substrate located on the pushing plane into the operating device.

[0009] The horizontal conveying mechanism has two parallel conveyor belts arranged on the conveyor frame along the horizontal length direction of the conveyor frame. Both ends of the two conveyor belts are provided with drive wheels and drive components. The drive wheels are respectively located at both ends of the conveyor frame. The first conveying section is located between the two conveyor belts and is provided with a first lifting plate and a first lifting drive component that can move up and down relative to the conveyor belts. The second conveying section is located between the two conveyor belts and is provided with a second lifting plate and a second lifting drive component that can move up and down relative to the conveyor belts.

[0010] By adopting the above technical solution, the conveyor frame supports the horizontal conveying mechanism, the lifting mechanism, and the pushing mechanism. The material frame containing the substrate is placed on the two conveyor belts of the first conveying section. The drive component and the transmission wheel drive the two conveyor belts to move the material frame. When the material frame is conveyed to the lifting mechanism, the lifting mechanism drives the material frame to move vertically upward so that each substrate in the material frame can move to the pushing plane. Then, the pushing mechanism pushes the substrates located on the pushing plane one by one into the substrate inlet of the operating device. When all the substrates in the material frame have been pushed, the lifting mechanism drives the empty material frame to move vertically downward so that the empty material frame returns to the conveyor belt. The conveyor belt continues to carry the empty material frame to the direction of the second conveying section. The material frame containing the substrate in the first conveying section can continue to be conveyed to the lifting mechanism for lifting and pushing loading operations. During the lifting operation, the first lifting drive unit drives the first lifting plate to move vertically upward, lifting the material frame containing the substrate in the first conveying section. This prevents the material frame in the first conveying section from being transported to the lifting mechanism and interfering with the lifting operation. Simultaneously, the second lifting drive unit drives the second lifting plate to move vertically upward, lifting the empty material frame in the second conveying section. This prevents continuous friction and wear between the continuously moving conveyor belt and the material frame in the second conveying section. Throughout the feeding process, the horizontal conveying and vertical lifting processes of the material frame do not interfere with each other, ensuring strong operational continuity and simplicity, thus improving the substrate feeding efficiency.

[0011] Preferably, the first conveying section is provided with a blocking mechanism for preventing the material frame from being conveyed to the lifting mechanism. The blocking mechanism includes a blocking plate and a blocking drive member. The blocking drive member is disposed on the conveyor frame and located at one end of the first conveying section near the lifting mechanism for driving the blocking plate to move up and down relative to the conveyor belts between the two conveyor belts.

[0012] By adopting the above technical solution, when a material frame containing a substrate is conveyed to the lifting mechanism, the blocking drive drives the blocking plate to move vertically upward, so that the blocking plate passes through the space between the two conveyor belts. The blocking plate blocks the material frame located on the first conveyor section to prevent it from being conveyed to the lifting mechanism, thereby avoiding interference between the material frame on the first conveyor section and the material frame located in the lifting mechanism. At the same time, the first lifting plate lifts the material frame on the first conveyor section, separating it from the conveyor belt to avoid wear caused by continuous friction between the continuously moving conveyor belt and the material frame. When the material frame in the lifting mechanism returns to the conveyor belt after the pushing operation is completed, the blocking drive drives the blocking plate to move vertically downward, and the first lifting plate descends to put the material frame on the first conveyor section back onto the conveyor belt, so that the material frame in the first conveyor section can continue to enter the lifting mechanism.

[0013] Preferably, the lifting mechanism includes a lifting block and a lifting drive. The lifting block is located on the substrate feed port side of the operating device to support the material frame. The lifting drive is disposed on the conveyor frame and located between the first conveyor section and the second conveyor section to drive the lifting block to move vertically up and down.

[0014] By adopting the above technical solution, when the material frame is conveyed to the lifting mechanism, the lifting block supports the material frame. The material frame is aligned vertically with the substrate inlet of the operating device. The lifting drive drives the lifting block to move vertically upward, so that the lifting block pushes the material frame vertically upward. Each substrate in the material frame can move to the pushing plane, so that the pushing mechanism can push the substrates in the material frame one by one into the operating device. After all the substrates in the material frame have been pushed into the operating device, the lifting drive drives the lifting block to move vertically downward, so that the material frame returns to the conveyor belt to continue conveying.

[0015] Preferably, the lifting drive includes a first support frame, a lead screw, and a lifting motor. The first support frame is fixedly connected to the bottom of the conveyor frame. The lead screw is vertically arranged. The lifting motor is fixedly arranged on the first support frame to drive the lead screw to rotate. The lifting block is threaded onto the lead screw. The two opposite side walls of the lifting block abut against and slide against the side walls of the first support frame.

[0016] By adopting the above technical solution, the first support frame supports the lead screw and the lifting motor. The lifting motor drives the lead screw to rotate. The side wall of the first support frame limits the two opposite side walls of the lifting block so that the rotating lead screw can drive the lifting block to move vertically up and down, thereby realizing the vertical up and down driving operation of the lifting block.

[0017] Preferably, the lifting block includes a support part and a connecting part that are fixedly connected at the top and bottom, the upper end of the lead screw is threaded through the connecting part from bottom to top, and there is a clearance space between the support part and the connecting part for the upper end of the lead screw to be threaded through.

[0018] By adopting the above technical solution, the support part supports the material frame. The support part is connected to the lead screw through the connecting part, and the threaded engagement between the connecting part and the lead screw drives the support part to move vertically up and down. The clearance space between the support part and the connecting part accommodates the upper end of the lead screw to prevent the upper end of the lead screw from passing through the upper end of the lifting block and interfering with the support operation. This setting can also reduce the weight of the lifting block, thereby facilitating the operation of the lifting motor and the lead screw to drive the lifting block to move.

[0019] Preferably, the lifting block is fixedly provided with a positioning plate, which is located on the side of the upper end of the lifting block near the second conveying section. When the material frame abuts against the positioning plate, the material frame is aligned vertically with the base plate feed port of the operating device.

[0020] By adopting the above technical solution, when the material frame with the substrate in the first conveying section is conveyed to the lifting block, the material frame abuts against the positioning plate, and the positioning plate positions the material frame so that the substrate in the material frame is aligned with the feed port of the operating equipment, which helps to improve the stability and accuracy of the material frame when it moves vertically up and down in the lifting mechanism.

[0021] Preferably, the pushing mechanism includes a pushing plate and a pushing drive. The pushing plate is located on the pushing plane and is horizontally arranged. The pushing drive is located on the side of the conveyor frame away from the operating device and between the first conveying section and the second conveying section, for driving the pushing plate to reciprocate in a direction closer to or farther from the substrate feed port of the operating device.

[0022] By adopting the above technical solution, when the lifting mechanism lifts the material frame until the substrate in it is located on the pushing plane, the pushing drive drives the pushing plate to move towards the feed port of the operating device, so as to push the substrate located on the pushing plane into the operating device. Then, the pushing drive drives the pushing plate to move away from the feed port of the operating device, so as to lift the next substrate in the material frame to the pushing plane to avoid it. By repeating the above operation, all the substrates in the material frame can be pushed into the operating device, which is convenient and fast.

[0023] Preferably, both ends of the first lifting plate are fixedly provided with first balancing components, the two sets of first balancing components are symmetrically arranged with respect to the first lifting drive component, and both sets of first balancing components are movably inserted through the conveyor frame.

[0024] By adopting the above technical solution, during the process of the first lifting drive component lifting the first lifting plate, the two sets of first balance components are symmetrically arranged at both ends of the first lifting plate to support both ends of the first lifting plate, which helps to improve the stability of the first lifting plate when lifting the material frame located in the first conveying section.

[0025] Preferably, a second balancing component is fixedly provided at both ends of the second lifting plate, and the two sets of the second balancing components are symmetrically arranged with respect to the second lifting drive component, and the two sets of the second balancing components are movably inserted through the conveyor frame.

[0026] By adopting the above technical solution, during the process of the second lifting drive component lifting the second lifting plate, the two sets of second balance components are symmetrically arranged at both ends of the second lifting plate to support both ends of the second lifting plate, which helps to improve the stability of the second lifting plate when lifting the material frame located in the second conveying section.

[0027] Preferably, the conveyor frame is provided with limiting plates on both sides along its length, and the opposite sides of the material frame slide against the opposite sides of the two limiting plates respectively.

[0028] By adopting the above technical solution, the two limiting plates limit the material frame during the horizontal conveying process, which helps to improve the stability of the material frame during the horizontal conveying process and also helps to improve the accuracy of aligning the substrate in the material frame with the feed inlet of the operating equipment.

[0029] The substrate feeding steps are as follows:

[0030] S1: The staff places multiple material frames containing substrates horizontally on the conveyor belt located in the first conveyor section for conveying. At this time, the upper surfaces of the first lifting plate, the second lifting plate and the lifting block are all lower than the plane where the conveyor belt is located, and the positioning plate passes through the position between the two conveyor belts.

[0031] S2: When the foremost material frame is conveyed on the conveyor belt to the top of the lifting block, the positioning plate blocks the material frame. The output shaft of the lifting motor rotates to drive the lead screw to rotate. The rotation of the lead screw drives the lifting block to move vertically upward. The lifting block pushes the material frame vertically upward so that each base plate in the material frame can move to the pushing plane during the vertical upward movement of the material frame. At the same time, during the vertical upward movement of the material frame, the piston rod of the blocking cylinder is stretched to drive the blocking plate to move vertically upward. The blocking plate passes through the top between the two conveyor belts to prevent the subsequent material frames from interfering with the lifting operation of the material frames located in the lifting mechanism. In addition, the piston rod of the first lifting cylinder is stretched to drive the first lifting plate to move vertically upward. At this time, the first lifting plate passes through the line between the two conveyor belts. The first lifting plate lifts the subsequent material frames from the conveyor belt to avoid continuous friction and wear caused by the continuous transmission of the conveyor belt and the blocked material frames located in the first conveying section.

[0032] S3: When the substrate in the material frame in the lifting mechanism moves to the pushing plane, the rodless cylinder pushes all the substrates in the material frame into the operating equipment one by one through the pushing plate.

[0033] S4: When all the substrates in the material frame in the lifting mechanism are pushed into the operating equipment, the output shaft of the lifting motor rotates in the opposite direction, causing the lead screw to rotate in the opposite direction. The lead screw drives the lifting block to move vertically downward, so that the lifting block and the limiting plate move to the bottom of the conveyor belt. The empty material frame returns to the conveyor belt and is conveyed in the direction of the second conveying section.

[0034] S5: The piston rod of the blocking cylinder retracts to drive the blocking plate to move vertically downward, and the piston rod of the first lifting cylinder retracts to drive the first lifting plate to move vertically downward, so that both the first lifting plate and the blocking plate are located below the conveyor belt. The material frame located in the first conveying section can continue to be conveyed to the lifting mechanism for the next round of lifting and pushing operation. Repeating the above operation can realize the automated feeding operation of the substrate. The above operation does not require manual intervention. In the entire feeding process, the horizontal conveying process of the material frame and the vertical lifting process do not interfere with each other, and the operation is highly continuous. The operator only needs to place the material frame containing the substrate in the first conveying section and then take out the empty material frame from the second conveying section. The operation is simple and helps to improve the feeding efficiency of the substrate.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. By setting up a horizontal conveying mechanism, a lifting mechanism, and a pushing mechanism, when the first conveying section of the horizontal conveying mechanism conveys the material frame to the lifting mechanism, the lifting mechanism drives the material frame to move vertically upward so that each substrate in the material frame can move to the pushing plane. Then, the pushing mechanism pushes the substrates located on the pushing plane one by one into the substrate inlet of the operating device. When all the substrates in the material frame have been pushed, the lifting mechanism drives the empty material frame to move vertically downward so that the empty material frame returns to the conveyor belt. The conveyor belt continues to carry the empty material frame to the direction of the second conveying section. The material frame containing substrates in the first conveying section can continue to be conveyed to the lifting mechanism for lifting and pushing loading operations. During the lifting operation, the first lifting drive unit drives the first lifting plate to move vertically upward, lifting the material frame containing the substrate in the first conveying section. This prevents the material frame in the first conveying section from being transported to the lifting mechanism and interfering with the lifting operation. Simultaneously, the second lifting drive unit drives the second lifting plate to move vertically upward, lifting the empty material frame in the second conveying section. This prevents continuous friction and wear between the continuously moving conveyor belt and the material frame in the second conveying section. Throughout the feeding process, the horizontal conveying and vertical lifting processes of the material frame do not interfere with each other, ensuring strong operational continuity and simplicity, thus improving the substrate feeding efficiency.

[0037] 2. By setting up a baffle plate and a baffle drive, when a material frame containing a substrate is conveyed to the lifting mechanism, the baffle drive drives the baffle plate to move vertically upward, so that the baffle plate passes over the space between the two conveyor belts. The baffle plate blocks the material frame located on the first conveyor section to prevent it from being conveyed to the lifting mechanism, thereby avoiding interference between the material frame on the first conveyor section and the material frame located in the lifting mechanism. At the same time, it works in conjunction with the first lifting plate to lift the material frame on the first conveyor section, separating it from the conveyor belt to avoid wear caused by continuous friction between the continuously moving conveyor belt and the material frame. When the material frame in the lifting mechanism returns to the conveyor belt after the pushing operation is completed, the baffle drive drives the baffle plate to move vertically downward, and at the same time, it works in conjunction with the first lifting plate to lower and put the material frame on the first conveyor section back onto the conveyor belt, so that the material frame in the first conveyor section can continue to enter the lifting mechanism.

[0038] 3. By setting up a support part and a connecting part, the support part supports the material frame, and the support part is connected to the lead screw through the connecting part. The threaded engagement between the connecting part and the lead screw drives the support part to move vertically up and down. The clearance space between the support part and the connecting part accommodates the upper end of the lead screw to prevent the upper end of the lead screw from passing through the upper end of the lifting block and interfering with the support operation. This setting can also reduce the weight of the lifting block, thereby facilitating the operation of the lifting motor and the lead screw to drive the lifting block. Attached Figure Description

[0049] The following is in conjunction with the appendix Figure 2-8 This application will be described in further detail.

[0050] This application discloses a feeding device for a substrate handling equipment, referring to... Figure 2This feeding device is used to feed substrates onto one side of the substrate inlet of the operating device 1. The operating device can be a marking device, such as an automated marking device, or a testing device, such as an automated testing device. Such devices require the substrates to be transported and operated one by one. The substrates are usually stored in a material frame 19. Each material frame 19 includes at least multiple layers for placing substrates. Therefore, the material frame 19 must be transported first and then the substrates are transported. This feeding device can be matched with such devices to transport the material frame 19 containing the substrates and transport the substrates in the material frame 19 one by one to the corresponding operating device.

[0051] Reference Figure 2 The feeding device includes a horizontally arranged conveyor frame 2, which is fixedly installed on the outer side of the operating device 1 for feeding substrates. The conveyor frame 2 is equipped with a horizontal conveying mechanism 3, a lifting mechanism 4, and a pushing mechanism 5. The horizontal conveying mechanism 3 is horizontally arranged on the side of the operating device 1 where the substrate feed port is located for horizontally conveying the material frame 19. The horizontal conveying mechanism 3 includes a first conveying section 31 and a second conveying section 32. The lifting mechanism 4 is located between the first conveying section 31 and the second conveying section 32 and is located at the substrate feed port to drive the material frame 19 to move vertically up and down. The pushing mechanism 5 is located on the side of the lifting mechanism 4 away from the operating device 1. It should be noted that the pushing mechanism 5 has a pushing plane 6, which is directly opposite the substrate feed port of the operating device 1 in the horizontal direction.

[0052] During the substrate feeding process, the operator places the substrate-containing frame 19 in the first conveying section 31. The first conveying section 31 conveys the substrate-containing frame 19 to the lifting mechanism 4. The lifting mechanism 4 lifts the frame 19 so that each substrate in the frame 19 can move to the pushing plane 6. Then the pushing mechanism 5 pushes the substrates located on the pushing plane 6 one by one into the operating device 1. In actual production, taking a marking machine as an example, the length of the marking machine is generally 120cm and the width of the material frame 19 is generally 6cm. Existing vertical feeding conveying devices can only hold a maximum of three material frames 19 at a time (limited by the height of the equipment). However, by adopting the horizontal conveying method of this application, the width space of the equipment can be fully utilized. The first conveying section 31 can hold far more than three material frames 19 at a time, and can hold and convey at least eight material frames 19. Moreover, the conveying process of the material frames 19 in the horizontal direction and the lifting process in the vertical direction do not interfere with each other, resulting in strong work continuity. This greatly reduces the time and effort spent by personnel in the material loading operation, and the operation is simple, thereby helping to improve the feeding efficiency of the substrate.

[0053] Reference Figure 2 and Figure 3The horizontal conveying mechanism 3 has two parallel conveyor belts 7 arranged on the conveyor frame 2 along the horizontal length direction of the conveyor frame 2. The first conveying section 31 and the second conveying section 32 are both located between the two conveyor belts 7. Both ends of the two conveyor belts 7 are provided with drive wheels 8, and a drive assembly 9 is provided at either end. The drive wheels 8 are located at both ends of the conveyor frame 2. The two conveyor belts 7 are both wrapped around the drive wheels 8 located at both ends of the conveyor frame 2. The drive assembly 9 drives the drive wheels 8 to rotate, thereby driving the two conveyor belts 7 to perform transmission.

[0054] Reference Figure 3 The drive assembly 9 includes a conveyor motor 91 and a conveyor roller 92. The number of conveyor rollers 92 is set to two. The two conveyor rollers 92 are arranged in parallel and horizontally rotatably connected to the two ends of the conveyor frame 2. The transmission wheels 8 located at both ends of the conveyor frame 2 are respectively fixedly sleeved on the two conveyor rollers 92. The conveyor motor 91 is horizontally fixedly arranged at one end of the conveyor frame 2. The output shaft of the conveyor motor 91 is coaxially fixedly connected to one of the conveyor rollers 92 so that the rotation of the output shaft of the conveyor motor 91 drives the conveyor roller 92 to rotate. The conveyor roller 92 drives the conveyor belt 7 through the transmission wheel 8. When the material frame 19 is placed on the conveyor belt 7, the two conveyor belts 7 transport the material frame 19 based on the friction force, and the material frame 19 is transported with the transmission of the conveyor belt 7.

[0055] Reference Figure 3 Limiting plates 18 are provided on both sides of the conveyor frame 2 along its length. The gap between the two limiting plates 18 forms a channel for conveying the feeding frame 19. When the feeding frame 19 is placed on the conveyor belt 7, the opposite sides of the feeding frame 19 slide against the opposite sides of the two limiting plates 18 to limit the conveying process of the feeding frame 19. The feeding frame 19 is less likely to shake or deviate during the conveying process, which helps to improve the stability of the feeding frame 19 during the horizontal conveying process and also helps to improve the accuracy of the base plate aligning with the feed inlet of the operating device 1 when the feeding frame 19 moves into the lifting mechanism 4.

[0056] Reference Figure 4The first conveying section 31 is equipped with a blocking mechanism 14 for preventing the material frame 19 from being conveyed to the lifting mechanism 4. Specifically, the blocking mechanism 14 includes a blocking plate 141 and a blocking drive component. The blocking drive component is disposed on the conveyor frame 2 and located at the end of the first conveying section 31 near the lifting mechanism 4, and is used to drive the blocking plate 141 to move up and down relative to the two conveyor belts 7 between them. In this embodiment, the blocking drive component is configured as a blocking cylinder 142, which is fixedly disposed at the bottom of the conveyor frame 2, and the piston rod of the blocking cylinder 142 is vertically upward. The blocking plate 141 is vertically fixedly connected to the end of the piston rod of the blocking cylinder 142. The piston rod of the blocking cylinder 142 retracts to pull the blocking plate 141 vertically downward. The highest point of the blocking plate 141 is lower than the plane where the conveyor belt 7 is located, so that the material frame 19 in the first conveying section 31 can be conveyed to the lifting mechanism 4. When a material frame 19 is conveyed to the lifting mechanism 4, the piston rod of the blocking cylinder 142 extends to push the blocking plate 141 vertically upward. The blocking plate 141 extends from above between the two conveyor belts 7 to block the material frame 19 located in the first conveying section 31, so as to prevent the conveying operation of the material frame 19 located in the first conveying section 31 from interfering with the lifting operation of the material frame 19 in the lifting mechanism 4.

[0057] Reference Figure 4 The first conveying section 31 is equipped with a first lifting plate 10 and a first lifting drive component that can move up and down relative to the conveyor belt 7. In this embodiment, the first lifting drive component is a first lifting cylinder 11, which is vertically fixed to the bottom of the conveyor frame 2 located in the first conveying section 31. The first lifting plate 10 is horizontally positioned between the two conveyor belts 7 and is fixedly connected to the piston rod of the first lifting cylinder 11. When the material frame 19 containing the substrate is conveyed in the first conveying section 31, the piston rod of the first lifting cylinder 11 retracts to drive the first lifting plate 10 to move vertically downward. At this time, the upper surface of the first lifting plate 10 is lower than the plane of the conveyor belt 7, and the transmission of the conveyor belt 7 drives the material frame 19 to be conveyed. Figure 5When the baffle plate 141 blocks the movement of the material frame 19 in the first conveying section 31, the piston rod of the first lifting cylinder 11 is stretched to drive the first lifting plate 10 to move vertically upward. At this time, the first lifting plate 10 passes upward between the two conveyor belts 7, and the first lifting plate 10 lifts the material frame 19 located in the first conveying section 31 from the conveyor belt 7, and the material frame 19 stops conveying. A sensing device is provided near the lifting mechanism 4. When the material frame 19 is in the substrate feeding process, the sensing device sends a signal to the controller. The controller issues a command to the first lifting cylinder 11. The first lifting cylinder 11 drives the first lifting plate 12 to lift so that the material frame 19 is separated from the conveyor belt 7, and the material frame 19 stops conveying. However, the conveyor belt 7 can continue to run, which does not affect the material frame 19 discharge conveying in the second conveying section 32, and can effectively improve the conveying efficiency and continuity of the material frame 19. When the material frame 19 can continue to convey, the first lifting cylinder 11 drives the first lifting plate 12 to descend, and the material frame 19 is connected to the conveyor belt 7, so that the conveying of the material frame 19 can be resumed.

[0058] Reference Figure 6 The bottom of both ends of the first lifting plate 10 is fixedly provided with a first balancing component. The two sets of first balancing components are symmetrically arranged on the first lifting plate 10 relative to the first lifting cylinder 11. In this embodiment, the first balancing component is set as a first balancing column 16. The two sets of first balancing columns 16 are vertically and movably inserted through the conveyor frame 2. The two sets of first balancing columns 16 support the two ends of the first lifting plate 10 to improve the stability of the first lifting plate 10 when lifting the material frame 19 located in the first conveying section 31.

[0059] Reference Figure 4 and Figure 5 The lifting mechanism 4 includes a lifting block 41 and a lifting drive 42. The lifting block 41 is located on the substrate inlet side of the operating device 1. The lifting drive 42 is disposed on the conveyor frame 2 and located between the first conveyor section 31 and the second conveyor section 32 to drive the lifting block 41 to move vertically up and down. When the material frame 19 is conveyed to the lifting mechanism 4, the lifting block 41 supports the material frame 19. At this time, the material frame 19 is aligned vertically with the substrate inlet of the operating device 1. The lifting drive 42 drives the lifting block 41 to move vertically upward to push the material frame 19 to move vertically upward. Each substrate in the material frame 19 can move to the pushing plane 6 so that the pushing mechanism 5 can push the substrates in the material frame 19 into the operating device 1 one by one. After all the substrates in the material frame 19 have been pushed into the operating device 1, the lifting drive 42 drives the lifting block 41 to move vertically downward so that the empty material frame 19 returns to the conveyor belt 7 and is conveyed towards the second conveyor section 32.

[0060] Reference Figure 7The lifting drive component 42 includes a first support frame 421, a lead screw 422, and a lifting motor 423. The first support frame 421 is vertically fixed to the bottom of the conveyor frame 2 to support the lead screw 422, the lifting motor 423, and the lifting block 41. The lead screw 422 is vertically rotatable. The lifting motor 423 is vertically fixed to the bottom of the first support frame 421 to drive the lead screw 422 to rotate. Specifically, the bottom end of the lead screw 422 is coaxially fixedly connected to the output shaft of the lifting motor 423 so that the rotation of the output shaft of the lifting motor 423 can drive the lead screw 422 to rotate. The lifting block 41 is threaded onto the top end of the lead screw 422, and the two opposite side walls of the lifting block 41 abut against and slide against the side walls of the first support frame 421. In this embodiment, the lifting motor 423 is selected as a servo motor that can rotate in both directions.

[0061] Before the material frame 19 is conveyed to the lifting mechanism 4, the upper surface of the lifting block 41 is lower than the plane of the conveyor belt 7 so that the material frame 19 can be conveyed directly above the lifting block 41. When the material frame 19 is conveyed directly above the lifting block 41, the rotation of the output shaft of the lifting motor 423 drives the lead screw 422 to rotate. The side wall of the first support frame 421 limits the two opposite side walls of the lifting block 41 so that the rotation of the lead screw 422 can drive the lifting block 41 to move vertically upward. The lifting block 41 pushes the material frame 19 to move vertically upward. Each substrate in the material frame 19 can move to the pushing plane 6 during the vertical upward movement of the material frame 19, so that the pushing mechanism 5 pushes each substrate into the operating device 1. After all the substrates in the material frame 19 have been pushed into the operating device 1, the output shaft of the lifting motor 423 rotates in the opposite direction so that the empty material frame 19 moves vertically downward back to the conveyor belt 7 to continue to be conveyed in the direction of the second conveying section 32.

[0062] Reference Figure 7 The lifting block 41 includes a support part 411 and a connecting part 412 that are fixedly connected at the top and bottom. The upper end of the lead screw 422 is threaded through the connecting part 412 from bottom to top. There is a clearance space between the support part 411 and the connecting part 412 for the upper end of the lead screw 422 to be threaded through, so as to prevent the upper end of the lead screw 422 from passing through the upper end of the lifting block 41 and interfering with the support operation. The clearance space can reduce the weight of the lifting block 41, thereby reducing the resistance during the lifting operation.

[0063] Reference Figure 4 and Figure 7A positioning plate 15 is vertically fixed on the lifting block 41. The positioning plate 15 is located on the upper end of the lifting block 41 near the second conveying section 32. When the material frame 19 is conveyed to the top of the lifting block 41, the side wall of the material frame 19 abuts against the positioning plate 15. The positioning plate 15 prevents the material frame 19 from being conveyed backward and positions the material frame 19. At this time, the material frame 19 is aligned with the substrate feed port of the operating device 1 in the vertical direction to improve the stability of the substrate during the lifting process and the accuracy during the pushing process.

[0064] Reference Figure 8 The pushing mechanism 5 includes a pushing plate 51 and a pushing drive 52. The pushing plate 51 is located on the pushing plane 6 and is horizontally arranged. The pushing drive 52 is located on the side of the conveyor frame 2 away from the operating device 1 and between the first conveying section 31 and the second conveying section 32. It is used to drive the pushing plate 51 to reciprocate in a direction closer to or away from the substrate inlet of the operating device 1. The pushing drive 52 drives the pushing plate 51 to move away from the substrate inlet of the operating device 1 to avoid obstructing the vertical up-and-down movement of the lifting mechanism 4 driving the material frame 19. When a substrate in the material frame 19 moves to the pushing plane 6, the pushing drive 52 drives the pushing plate 51 to move closer to the substrate inlet of the operating device 1 to push the substrate located on the pushing plane 6 into the operating device 1.

[0065] Reference Figure 8 The pushing drive component 52 includes a second support frame 521 and a pushing cylinder. The second support frame 521 is vertically fixed to the top of the conveyor frame 2 and is located on the side of the conveyor frame 2 away from the operating device 1. In this embodiment, the pushing cylinder is a rodless cylinder 522, which is horizontally fixed on the second support frame 521 and faces the substrate feed port of the operating device 1. The pushing plate 51 is connected to the rodless cylinder 522. When the substrate in the material frame 19 is lifted to the pushing plane 6, the rodless cylinder 522 drives the pushing plate 51 to move towards the operating device 1 to push the substrate located on the pushing plane 6 into the operating device 1. Then, the rodless cylinder 522 drives the pushing plate 51 to move away from the operating device 1 to make way for the next substrate to move to the pushing plane 6. Repeating the above operation can push all the substrates in the material frame 19 into the operating device 1.

[0066] Reference Figure 4The second conveying section 32 is equipped with a second lifting plate 12 and a second lifting drive component that can move vertically relative to the conveyor belt 7. In this embodiment, the second lifting drive component is a second lifting cylinder 13, which is vertically fixed to the bottom of the conveyor frame 2 located in the second conveying section 32. The second lifting plate 12 is horizontally positioned between the two conveyor belts 7 and is fixedly connected to the piston rod of the second lifting cylinder 13. When the empty material frame 19 is conveyed in the second conveying section 32, the piston rod of the second lifting cylinder 13 retracts to drive the second lifting plate 12 to move vertically downward. At this time, the second lifting plate 12... The upper surface of 2 is lower than the plane of the conveyor belt 7. The transmission of the conveyor belt 7 drives the empty material frame 19 to be conveyed. When the lifting mechanism 4 lifts the material frame 19, the piston rod of the second lifting cylinder 13 is stretched to drive the second lifting plate 12 to move vertically upward. At this time, the second lifting plate 12 passes through the gap between the two conveyor belts 7 and lifts the empty material frame 19 located in the second conveying section 32 from the conveyor belt 7 to avoid continuous friction between the continuously driving conveyor belt 7 and the empty material frame 19 located in the second conveying section 32, which would cause wear.

[0067] Reference Figure 6 The bottom of both ends of the second lifting plate 12 is fixedly provided with second balancing components. The two sets of second balancing components are symmetrically arranged on the second lifting plate 12 relative to the second lifting cylinder 13. In this embodiment, the second balancing components are set as second balancing columns 17. The two sets of second balancing columns 17 are vertically and movably inserted through the conveyor frame 2. The two sets of second balancing columns 17 support the two ends of the second lifting plate 12 to improve the stability of the second lifting plate 12 when lifting the material frame 19 located in the second conveying section 32.

[0068] The implementation principle of a feeding device for a substrate handling equipment according to an embodiment of this application is as follows: When a substrate feeding operation is required, the operator arranges multiple substrate-containing frames 19 on the conveyor belt 7 located in the first conveying section 31 for conveying. At this time, the upper surfaces of the first lifting plate 10, the second lifting plate 12, and the lifting block 41 are all lower than the plane of the conveyor belt 7. The positioning plate 15 extends out from between the two conveyor belts 7. When the substrate-containing frame 19 is conveyed to directly above the lifting block 41, the positioning plate 15 lifts the frame 19. At block 9, the rotation of the output shaft of the lifting motor 423 drives the lead screw 422 to rotate. The side wall of the first support frame 421 limits the two opposite side walls of the lifting block 41 so that the rotation of the lead screw 422 can drive the lifting block 41 to move vertically upward. The lifting block 41 pushes the material frame 19 to move vertically upward. Each substrate in the material frame 19 can move to the pushing plane 6 during the vertical upward movement of the material frame 19. Then, the rodless cylinder 522 pushes all the substrates in the material frame 19 into the operating device 1 one by one through the pushing plate 51.

[0069] Simultaneously, the piston rod of the blocking cylinder 142 extends to drive the blocking plate 141 to move vertically upward. The blocking plate 141 extends above the space between the two conveyor belts 7 to prevent the conveying operation of the material frame 19 located in the first conveying section 31 from interfering with the lifting operation of the material frame 19 located in the lifting mechanism 4. The piston rod of the first lifting cylinder 11 extends to drive the first lifting plate 10 to move vertically upward. At this time, the first lifting plate 10 extends upward between the two conveyor belts 7, and the first lifting plate 10 lifts the material frame 19 located in the first conveying section 31. The frame 19 is lifted off the conveyor belt 7 to prevent continuous friction between the continuously driving conveyor belt 7 and the frame 19 located in the first conveyor section 31, which causes wear. The piston rod of the second lifting cylinder 13 is stretched to drive the second lifting plate 12 to move vertically upward. At this time, the second lifting plate 12 passes upward between the two conveyor belts 7. The second lifting plate 12 lifts the frame 19 located in the second conveyor section 32 off the conveyor belt 7 to prevent continuous friction between the continuously driving conveyor belt 7 and the frame 19 located in the second conveyor section 32, which causes wear.

[0070] After all the substrates in the material frame 19 in the lifting mechanism 4 are pushed into the operating device 1, the output shaft of the lifting motor 423 rotates in the reverse direction, driving the lead screw 422 to rotate in the reverse direction. The lead screw 422 drives the lifting block 41 to move vertically downward, so that the lifting block 41 and the limiting plate 18 move to the bottom of the conveyor belt 7. The empty material frame 19 returns to the conveyor belt 7 and is conveyed in the direction of the second conveying section 32. At the same time, the piston rod of the blocking cylinder 142 retracts to drive the blocking plate 141 to move vertically downward, the piston rod of the first lifting cylinder 11 retracts to drive the first lifting plate 10 to move vertically downward, and the piston rod of the second lifting cylinder 13 retracts to drive the second lifting plate 12 to move vertically downward. At this time, the first lifting plate 10, the blocking plate 141 and the second lifting plate 12 are all located below the conveyor belt 7. The material frame 19 located in the first conveying section 31 can continue to be conveyed to the lifting mechanism 4 for the next round of lifting and pushing operation.

[0071] The operation of placing the substrate-containing frame 19 into the horizontal conveying mechanism 3 in the first conveying section 31 and the operation of removing the empty frame 19 from the horizontal conveying mechanism 3 in the second conveying section 32, as well as the lifting operation of the frame 19 in the lifting mechanism 4, do not interfere with each other. The operation is highly continuous, and the actions of each stage are distinct, which is easy to control and simple to operate, thereby improving the substrate feeding efficiency.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
