Description

Technical Field

[0001] This invention relates to the field of chip processing equipment technology, and more specifically to a fixture conveying system. Background Technology

[0002] In chip manufacturing, long jigs (such as strip trays for carrying multiple chips) need to be transported between photolithography, etching, and other processes via a conveyor system. Traditional jig conveyor systems have a fixed conveyor line width, which can only accommodate long jigs of a single length. However, chip manufacturing processes often require switching to long jigs with different load capacities according to production needs (e.g., the length of a long jig carrying 8 chips differs significantly from that of a long jig carrying 12 chips). A fixed-width conveyor line cannot accommodate long jigs of different lengths—if the jig length is less than the preset width of the conveyor line, it is prone to conveying deviation due to lateral instability; if the jig length is greater than the preset width, it cannot be placed on the conveyor line, requiring manual replacement or equipment adjustment, resulting in low changeover efficiency, production cycle interruption, and seriously affecting chip manufacturing efficiency. Summary of the Invention

[0003] In view of this, the object of the present invention is to provide a jig conveying system to solve the problems mentioned in the background art.

[0004] This invention is achieved through the following technical solution: A jig conveying system includes a base, on the top surface of which a first conveyor line is fixedly mounted and a second conveyor line is slidably mounted, the first and second conveyor lines being arranged parallel to each other. A third and fourth conveyor line are also fixedly mounted on the top surface of the base, the tail end of the third conveyor line corresponding to the head ends of the first and second conveyor lines, and the head end of the fourth conveyor line corresponding to one side of the tail end of the first conveyor line. The second conveyor line is connected to the base via a sliding assembly. A drive assembly is also fixedly mounted on the top surface of the base, threadedly engaged with the sliding assembly, and used to adjust the distance between the first and second conveyor lines.

[0005] The drive component fixed on the base is threaded into the sliding component connected to the second conveyor line, which drives the second conveyor line to slide. This adjusts the distance between the second and the fixedly installed first conveyor line, making the distance between them suitable for long jigs of different lengths. At the same time, the third and fourth conveyor lines work together to realize the transfer of the jig between different conveyor lines, avoiding problems such as conveyor offset, inability to be placed, or need for manual adjustment due to jig length mismatch, thus ensuring chip processing efficiency.

[0006] Furthermore, the sliding assembly includes a fixed plate, a fixed block, a first slide groove, and a slide plate. The fixed block is fixedly installed on the top surface of the fixed plate, and the fixed block is fixedly connected to one side of the second conveyor line by bolts. The first slide groove is opened on the top surface of the base, one end of the slide plate is fixedly connected to the bottom surface of the fixed plate, and the other end is slidably engaged in the first slide groove.

[0007] When the position of the second conveyor line needs to be adjusted to change its distance from the first conveyor line, the drive assembly is activated to generate driving force. Because the drive assembly and the fixed plate in the sliding assembly (which is indirectly connected to the second conveyor line through a fixed block fixed to the fixed plate) have a threaded engagement, this driving force pushes the fixed plate to move. As the fixed plate moves, it drives a sliding plate fixed to its bottom surface. The sliding plate slides along a first groove on the top surface of the base, providing stable guidance for the movement of the fixed plate and the second conveyor line. The fixed block securely connects the second conveyor line to the fixed plate with bolts, allowing the second conveyor line to move synchronously with the fixed plate. This enables precise adjustment of the second conveyor line's position to adapt to the conveying needs of long jigs of different lengths.

[0008] Furthermore, the drive assembly includes a motor, a lead screw, and a connecting plate. The motor is mounted on the top surface of the base, the connecting plate is fixedly connected to the bottom surface of the fixed plate, one end of the lead screw is fixedly connected to the motor output shaft, and the other end is threadedly engaged with the connecting plate.

[0009] When it is necessary to adjust the distance between the second conveyor line and the first conveyor line, the motor is started. The motor drives the output shaft and the lead screw to rotate. The rotation of the lead screw drives the connecting plate to move. At the same time, the slide plate slides along the first slide groove opened on the top surface of the base. This can prevent the second fixed plate from rotating with the lead screw and also provide stable guidance for the movement of the fixed plate and the second conveyor line, so as to realize the adjustment of the position of the second conveyor line to meet the conveying requirements of long strip fixtures of different lengths.

[0010] Furthermore, a first pushing component is fixedly installed on one side of the tail end of the third conveyor line. The first pushing component is used to push the fixture located at the tail end of the third conveyor line to the head end of the first and second conveyor lines.

[0011] When the long jig is conveyed to the end of the third conveyor line, the first pushing component fixedly installed on one side of the end is activated. It generates a thrust on the jig, using mechanical pushing to overcome the friction and other resistance between the jig and the surface of the conveyor line and the surrounding environment. The jig is accurately pushed from the end of the third conveyor line to the head position of the first and second conveyor lines, so as to realize the transfer and transportation of the jig between different conveyor lines and ensure that the jig can smoothly enter the subsequent conveyor line with the appropriate spacing for transportation.

[0012] Furthermore, the first pushing component includes a first support plate, a reciprocating pushing mechanism, and a push plate. The first support plate is fixedly installed on one side of the tail end of the third conveyor line, the reciprocating pushing mechanism is fixedly installed on the top surface of the first support plate, the output end of the reciprocating pushing mechanism is fixedly connected to the push plate, and the push plate corresponds to the head end of the first conveyor line and the head end of the second conveyor line.

[0013] When the long jig reaches the end of the third conveyor line, the reciprocating push mechanism, which is fixedly installed on the top surface of the first support plate on one side of the end of the third conveyor line, is activated. Its output end performs a linear reciprocating motion. Since the output end is fixedly connected to the push plate, it drives the push plate to move synchronously. Driven by the reciprocating push mechanism, the push plate extends towards the position corresponding to the beginning of the first and second conveyor lines. After contacting the jig, it applies a pushing force, smoothly and accurately pushing the jig from the end of the third conveyor line to the beginning of the first and second conveyor lines, completing the transfer of the jig between different conveyor lines for subsequent conveying and processing.

[0014] Furthermore, a stop block is fixedly installed on one side of the second conveyor head end, and a movable groove is opened at the end of the push plate near the stop block. A movable block is slidably fitted inside the movable groove, and a return spring is installed inside the movable groove. The two ends of the return spring are fixedly connected to one end of the movable block and the inner wall of the movable groove, respectively. The end of the movable block away from the return spring abuts against one side of the stop block.

[0015] When the distance between the first and second conveyor lines is at its maximum, the return spring is in a freely extended state. When the distance between the first and second conveyor lines decreases, the return spring changes from a freely extended state to a retracted state. At the same time, the movable block slides in the movable groove as the return spring extends or retracts. The end away from the return spring is always in contact with the side of the stop block. With the help of the push plate, long jigs of different lengths can be pushed.

[0016] Furthermore, a first bearing plate is provided between the head ends of the first conveyor line and the second conveyor line. The two opposite ends of the first bearing plate are fixedly connected to the opposite sides of the first conveyor line and the second conveyor line, respectively. The first bearing plate consists of a first movable plate and a second movable plate. A first connecting cavity is opened inside the first movable plate. Two second sliding grooves are also opened inside the first movable plate. The two second sliding grooves are located on opposite sides of the first connecting cavity and communicate with the first connecting cavity. A first connecting block adapted to the first connecting cavity is fixedly connected to one side of the second movable plate. A first slider is fixedly connected to both opposite sides of the first connecting block. The first slider slides in the second sliding groove.

[0017] The first support plate connects the first conveyor line and the head end of the second conveyor line, and is composed of a first movable plate and a second movable plate. The second movable plate is embedded in the first connecting cavity of the first movable plate through a first connecting block on one side, and the first sliders on both sides of the first connecting block slide in the second groove of the first movable plate that communicates with the first connecting cavity. When the distance between the first conveyor line and the second conveyor line changes, the first support plate can still maintain a stable connection between the first conveyor line and the second conveyor line, providing reliable support for the fixture between their head ends, ensuring the stability and accuracy of the fixture during the conveying process, and avoiding abnormal fixture conveying due to changes in the distance between the conveyor lines.

[0018] Furthermore, a second bearing plate is provided between the tail ends of the first conveyor line and the second conveyor line. The two opposite ends of the second bearing plate are fixedly connected to the opposite sides of the first conveyor line and the second conveyor line, respectively. The second bearing plate consists of a third movable plate and a fourth movable plate. The third movable plate has a second connecting cavity inside and two third sliding grooves inside. The two third sliding grooves are located on opposite sides of the second connecting cavity and communicate with the second connecting cavity. A second connecting block adapted to the second connecting cavity is fixedly connected to one side of the fourth movable plate. A second slider is fixedly connected to both opposite sides of the second connecting block. The second slider slides in the third sliding groove.

[0019] The second support plate connects the tail ends of the first and second conveyor lines and is composed of a third and a fourth movable plate. When the distance between the first and second conveyor lines changes due to adjustment, the fourth movable plate moves within the second connecting cavity of the third movable plate via a second connecting block on one side. Simultaneously, the second sliders on both sides of the second connecting block slide along the third sliding grooves that communicate with the second connecting cavity and are located on opposite sides of it. This allows the fourth movable plate to slide relative to the third movable plate, enabling the length of the second support plate to adapt to changes in the distance between the first and second conveyor lines, ensuring a stable connection between their tail ends and guaranteeing that the long fixture can smoothly transition and be transported from the tail ends of the first and second conveyor lines to the fourth conveyor line.

[0020] Furthermore, a second pushing component is fixedly installed at the tail end of the second conveyor line. The second pushing component is used to push the fixture located at the tail ends of the first and second conveyor lines to the head end of the fourth conveyor line.

[0021] When the long jig is conveyed to the tail ends of the first and second conveyor lines, the second pushing component, fixedly installed at the tail end of the second conveyor line, begins to operate. The second pushing component generates a pushing force that acts directly on the jig located at the tail ends of the first and second conveyor lines, smoothly and accurately pushing the jig along a predetermined direction from the tail ends of the first and second conveyor lines to the head end of the fourth conveyor line. This enables the jig to move between different conveyor lines, ensuring the continuity and efficiency of jig transport during chip processing.

[0022] Furthermore, the second push assembly includes a second support plate, an electric guide rail, two slides, two Z-plates, and a push block. The second support plate is fixedly installed on the top surface of the tail end of the second conveyor line. Both slides are fixedly installed on the second support plate. The electric guide rail slides on the two slides. One end of each of the two Z-plates is fixedly connected to the electric guide rail, and the other end is fixedly connected to the push plate.

[0023] When it is necessary to push the fixture located at the end of the first and second conveyor lines to the beginning of the fourth conveyor line, the electric guide rail is activated, allowing it to move linearly along the slide table. Simultaneously, one end of each of the two Z-plates is fixedly connected to the electric guide rail, and the other end is fixedly connected to a push block. As the electric guide rail moves, it drives the two Z-plates and the push block to move synchronously. During this movement, the push block contacts the fixture and applies a pushing force, smoothly pushing the fixture from the end of the first and second conveyor lines to the beginning of the fourth conveyor line, completing the transfer and transport of the fixture between different conveyor lines.

[0024] The beneficial effects of this invention are as follows: 1. The second conveyor line is connected to the base via a sliding assembly. The sliding assembly includes a fixed plate, a fixed block, a first slide groove, and a slide plate. The drive assembly is threaded into the sliding assembly and can be driven by a motor to rotate the lead screw, thereby moving the connecting plate and the fixed plate and adjusting the distance between the first conveyor line and the second conveyor line. This can adapt to the conveying process requirements of long jigs of different lengths.

[0025] 2. The first and second bearing plates maintain a stable connection during the adjustment of the distance between the first and second conveyor lines, providing reliable support for the transition of the fixture between the conveyor lines. This effectively avoids problems such as shaking, jamming, or even falling of the fixture due to changes in the distance between the conveyor lines during the conveying process, improving the stability and reliability of the fixture conveying and reducing the product damage rate and production failure rate.

[0026] 3. The entire conveying process is achieved through automated components such as motors, reciprocating drive mechanisms, and electric guide rails, reducing manual intervention, improving the degree of automation and production efficiency, and reducing labor intensity and labor costs.

[0034] Please see Figure 1-9This invention provides a technical solution: a jig conveying system, including a base 1. A first conveyor line 2 is fixedly installed on the top surface of the base 1, and a second conveyor line 3 is slidably installed thereon. The first conveyor line 2 and the second conveyor line 3 are arranged in parallel. A third conveyor line 4 and a fourth conveyor line 5 are also fixedly installed on the top surface of the base 1. The tail end of the third conveyor line 4 corresponds to the head end of the first conveyor line 2 and the second conveyor line 3. A first pushing component 8 is fixedly installed on one side of the tail end of the third conveyor line 4. The first pushing component 8 is used to push the jig located at the tail end of the third conveyor line 4 to the head end of the first conveyor line 2 and the second conveyor line 3. The first pushing component 8 includes a first support plate 81, a reciprocating pushing mechanism 82, and a push plate 83. The first support plate 81 is fixedly installed on one side of the tail end of the third conveyor line 4. The reciprocating pushing mechanism 82 is fixedly installed on the top surface of the first support plate 81. The output end of the reciprocating pushing mechanism 82 is fixedly connected to the push plate 83. The push plate 83 corresponds to the head end of the first conveyor line 2 and the second conveyor line 3. The reciprocating push mechanism 82 can be a pneumatic cylinder or a hydraulic cylinder. A stop block 9 is fixedly installed on one side of the head end of the second conveyor line 3. A movable groove 10 is opened at the end of the push plate 83 near the stop block 9. A movable block 11 is slidably fitted inside the movable groove 10. A return spring 12 is installed inside the movable groove 10. Both ends of the return spring 12 are fixedly connected to one end of the movable block 11 and the inner wall of the movable groove 10, respectively. The end of the movable block 11 away from the return spring 12 abuts against one side of the stop block 9. When the distance between the first conveyor line 2 and the second conveyor line 3 is at its maximum, the return spring 12 is in a freely extended state. When the distance between the first conveyor line 2 and the second conveyor line 3 decreases, the return spring 12 changes from a freely extended state to a retracted state. At the same time, the movable block 11 slides in the movable groove 10 as the return spring 12 extends or retracts. The end away from the return spring 12 always abuts against one side of the stop block 9. With the help of the push plate 83, long strip fixtures of different lengths can be pushed. The head end of the fourth conveyor line 5 corresponds to one side of the tail end of the first conveyor line 2. The second conveyor line 3 is connected to the base 1 via a sliding assembly 6. The sliding assembly 6 includes a fixed plate 61, a fixed block 62, a first slide groove 63, and a sliding plate 64. The fixed block 62 is fixedly installed on the top surface of the fixed plate 61 and is fixedly connected to one side of the second conveyor line 3 by bolts. The first slide groove 63 is opened on the top surface of the base 1. One end of the sliding plate 64 is fixedly connected to the bottom surface of the fixed plate 61, and the other end is slidably engaged in the first slide groove 63. A drive assembly 7 is also fixedly installed on the top surface of the base 1. The drive assembly 7 is threadedly engaged with the sliding assembly 6. The drive assembly 7 is used to adjust the distance between the first conveyor line 2 and the second conveyor line 3. The drive assembly 7 includes a motor 71, a lead screw, and a connecting plate 73. The motor 71 is installed on the top surface of the base 1, and the connecting plate 73 is fixedly connected to the bottom surface of the fixed plate 61. One end of the lead screw is fixedly connected to the output shaft of the motor 71, and the other end is threadedly engaged with the connecting plate 73.When the position of the second conveyor line 3 needs to be adjusted to change its distance from the first conveyor line 2, the drive assembly 7 is activated to generate driving force. Because the drive assembly 7 and the fixed plate 61 in the sliding assembly 6 (which is indirectly associated with the second conveyor line 3 through connection with the fixed block 62 fixed on the fixed plate 61) have a threaded engagement, this driving force pushes the fixed plate 61 to move. When the fixed plate 61 moves, it drives the slide plate 64 fixed on its bottom surface. The slide plate 64 slides along the first slide groove 63 opened on the top surface of the base 1, providing stable guidance for the movement of the fixed plate 61 and the second conveyor line 3. The fixed block 62 fixes the second conveyor line 3 to the fixed plate 61 with bolts, so that the second conveyor line 3 moves synchronously with the fixed plate 61, thereby realizing the precise adjustment of the position of the second conveyor line 3 to adapt to the conveying needs of long strip fixtures of different lengths.

[0035] A first support plate 13 is provided between the head ends of the first conveyor line 2 and the second conveyor line 3. The two opposite ends of the first support plate 13 are fixedly connected to the opposite sides of the first conveyor line 2 and the second conveyor line 3, respectively. The first support plate 13 is composed of a first movable plate 131 and a second movable plate 132. A first connecting cavity 14 is opened inside the first movable plate 131. Two second sliding grooves 15 are also opened inside the first movable plate 131. The two second sliding grooves 15 are located on opposite sides of the first connecting cavity 14 and communicate with the first connecting cavity 14. A first connecting block 16 adapted to the first connecting cavity 14 is fixedly connected to one side of the second movable plate 132. A first slider 17 is fixedly connected to both opposite sides of the first connecting block 16. The first slider 17 slides in the second sliding groove 15. When the distance between the first conveyor line 2 and the second conveyor line 3 changes due to adjustment, the second movable plate 132 moves within the first connecting cavity 14 of the first movable plate 131 via the first connecting block 16 on one side. At the same time, the first sliders 17 on both sides of the first connecting block 16 slide along the second sliding grooves 15 that are connected to the first connecting cavity 14 and located on opposite sides of it. This enables the second movable plate 132 to slide relative to the first movable plate 131, allowing the length of the first bearing plate 13 to adapt to the change in the distance between the first conveyor line 2 and the second conveyor line 3, and to always stably connect the head ends of the first conveyor line 2 and the second conveyor line 3. This ensures that the long strip fixture can smoothly transition and be transported to the head ends of the first conveyor line 2 and the second conveyor line 3 at the tail end of the third conveyor line 4.

[0036] A second support plate 18 is provided between the tail ends of the first conveyor line 2 and the second conveyor line 3. The two ends of the second support plate 18 are fixedly connected to the opposite sides of the first conveyor line 2 and the second conveyor line 3, respectively. The second support plate 18 is composed of a third movable plate 181 and a fourth movable plate 182. The third movable plate 181 has a second connecting cavity 19 inside. The third movable plate 181 also has two third sliding grooves 20 inside. The two third sliding grooves 20 are located on opposite sides of the second connecting cavity 19 and communicate with the second connecting cavity 19. A second connecting block 21 that is adapted to the second connecting cavity 19 is fixedly connected to one side of the fourth movable plate 182. A second slider 22 is fixedly connected to both opposite sides of the second connecting block 21. The second slider 22 slides in the third sliding groove 20. When the distance between the first conveyor line 2 and the second conveyor line 3 changes due to adjustment, the fourth movable plate 182 moves within the second connecting cavity 19 of the third movable plate 181 via the second connecting block 21 on one side. At the same time, the second sliders 22 on both sides of the second connecting block 21 slide along the third sliding groove 20 that communicates with the second connecting cavity 19 and is located on opposite sides of it. This enables the fourth movable plate 182 to slide relative to the third movable plate 181, allowing the length of the second bearing plate 18 to adapt to the change in the distance between the first conveyor line 2 and the second conveyor line 3, and to always stably connect the tail ends of the two. This ensures that the long strip fixture can smoothly transition and be transported to the fourth conveyor line 5 at the tail ends of the first conveyor line 2 and the second conveyor line 3.

[0037] A second pushing component 23 is fixedly installed at the tail end of the second conveyor line 3. The second pushing component 23 is used to push the fixture located at the tail end of the first conveyor line 2 and the second conveyor line 3 to the head end of the fourth conveyor line 5. The second pushing component 23 consists of a second support plate 231, an electric guide rail 233, two slides 232, two Z-plates 234, and a pusher block 235. The second support plate 231 is fixedly installed on the top surface of the tail end of the second conveyor line 3. The two slides 232 are both fixedly installed on the second support plate 231. The electric guide rail 233 is slidably engaged with the two slides 232. One end of each of the two Z-plates 234 is fixedly connected to the electric guide rail 233, and the other end is fixedly connected to the pusher block 235.

[0038] Specific working principle: 1. Initial State and Fixture Loading: The system is in its initial state. The first conveyor line 2 is fixed to the base 1. The second conveyor line 3 can slide relative to the first conveyor line 2 via the sliding component 6. The first support plate 13 connects the head ends of the first conveyor line 2 and the second conveyor line 3, and the second support plate 18 connects the tail ends of the first conveyor line 2 and the second conveyor line 3. The long fixture is placed on the third conveyor line 4, and the third conveyor line 4 is started to transport the fixture to the tail end.

[0039] 2. The first pushing component 8 pushes the fixture: When the fixture reaches the end of the third conveyor line 4, it will be blocked by the stop block 9, and the first pushing component 8 will start working. The reciprocating pushing mechanism 82 will start, and its output end will drive the push plate 83 to move forward. The fixture will be pushed smoothly and accurately from the end of the third conveyor line 4 to the beginning of the first conveyor line 2 and the second conveyor line 3.

[0040] 3. Adjusting the distance between the first conveyor line 2 and the second conveyor line 3: The distance between the first conveyor line 2 and the second conveyor line 3 needs to be adjusted according to the size requirements of different long jigs. The motor 71 starts, and its output shaft drives the lead screw to rotate. Since the lead screw is threadedly engaged with the connecting plate 73 fixed to the bottom surface of the fixed plate 61, the rotation of the lead screw causes the connecting plate 73 to move the fixed plate 61. The sliding plate 64 on the bottom surface of the fixed plate 61 slides within the first sliding groove 63 on the top surface of the base 1, providing stable guidance for the movement of the fixed plate 61. Simultaneously, the second conveyor line 3 is fixedly connected to the fixed plate 61 via the fixing block 62, allowing the second conveyor line 3 to move synchronously with the fixed plate 61, thereby achieving the adjustment of the distance between the first conveyor line 2 and the second conveyor line 3.

[0041] 4. Adaptive Adjustment of Bearing Plate: During the adjustment of the distance between the first conveyor line 2 and the second conveyor line 3, the first bearing plate 13 and the second bearing plate 18 will automatically adapt to the change in distance. The first movable plate 131 and the second movable plate 132 of the first bearing plate 13 slide relative to the first movable plate 131 through the sliding cooperation of the first connecting block 16 and the first slider 17 in the first connecting cavity 14 and the second sliding groove 15. This allows the length of the first bearing plate 13 to adapt to the change in the distance between the first conveyor line 2 and the second conveyor line 3, and to always stably connect the two ends. This ensures that the long fixture can smoothly transition and be transported to the beginning of the first conveyor line 2 and the second conveyor line 3 at the end of the third conveyor line 4. Similarly, the third movable plate 181 and the fourth movable plate 182 of the second bearing plate 18 slide relative to the third movable plate 181 through the sliding cooperation of the second connecting block 21 and the second slider 22 in the second connecting cavity 19 and the third sliding groove 20. This allows the length of the second bearing plate 18 to adapt to the change in the distance between the first conveyor line 2 and the second conveyor line 3, and to always stably connect the tail ends of the two. This ensures that the long strip fixture can smoothly transition and be conveyed to the fourth conveyor line 5 at the tail ends of the first conveyor line 2 and the second conveyor line 3.

[0042] 5. The fixture is conveyed on the first conveyor line 2 and the second conveyor line 3: The first conveyor line 2 and the second conveyor line 3 start synchronously to convey the long fixture to the tail end. During the conveying process, the first bearing plate 13 and the second bearing plate 18 provide stable support for the long fixture to ensure smooth conveying.

[0043] 6. Second Pushing Component 23 Pushes the Fixture: When the long fixture is conveyed to the tail end of the first conveyor line 2 and the second conveyor line 3, the second pushing component 23 begins to operate. The electric guide rail 233 slides on the two slide tables 232, driving the two Z-plates 234 and the push block 235 to move synchronously. During the movement, the push block 235 contacts the fixture and applies a pushing force, smoothly pushing the fixture from the tail end of the first conveyor line 2 and the second conveyor line 3 to the head end of the fourth conveyor line 5. At the same time, the second support plate 18 can prevent the fixture from falling into the gap between the first conveyor line 2 and the second conveyor line 3, completing the movement of the fixture throughout the entire conveying system.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
