Description

Technical Field

[0001] This utility model relates to the field of excimer laser technology, specifically to a conveying device for an outer shell cover. Background Technology

[0002] In modern industrial manufacturing and scientific research, excimer lasers, with their high energy and short wavelength characteristics, are widely used in key fields such as semiconductor lithography, medical equipment, and material surface treatment. As related industries continue to increase their requirements for equipment precision and production efficiency, the assembly process of excimer lasers is also facing higher challenges. Among them, the assembly of the outer shell and cover is an important process to ensure the laser's sealing, stability, and overall performance. Its level of automation and conveying accuracy directly affect the quality of the final product and production efficiency.

[0003] In the traditional assembly process of excimer laser housings and covers, the conveying of covers mostly relies on manual operation or simple conveying equipment. On the one hand, manual conveying requires operators to carry each cover to the assembly station one by one, which is not only labor-intensive and costly, but also prone to deviations in the placement of covers due to human error, thus affecting the accuracy of subsequent pressing processes and potentially causing damage to the covers or housings, reducing the product qualification rate. On the other hand, existing simple conveying equipment can usually only achieve linear conveying of a single cover and cannot achieve the connection between centralized stacking and orderly conveying of covers. Such equipment often requires frequent manual replenishment of covers, resulting in interruptions in the conveying process, poor production continuity, and difficulty in meeting the needs of large-scale, high-efficiency assembly. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a conveying device for an outer shell cover, comprising a frame, on which a double-chain conveyor is mounted, and stacking and transfer components are respectively mounted at the beginning and end of the double-chain conveyor, as well as a baffle at the end of the double-chain conveyor and side blocks on both sides of the double-chain conveyor; the stacking component includes a frame structure, with double-layer support parts on both sides of the frame structure, and opposing thrust cylinders are mounted on the plates of the double-layer support parts, wherein the piston rods of two opposing thrust cylinders are fixed with convex-shaped opposing thrust blocks; a lifting component is also mounted on the frame below the frame structure, and a top plate is fixed to the lifting end of the lifting component.

[0005] Furthermore, the frame structure includes four L-shaped uprights locked and fixed on the frame platform, forming a rectangular placement area between the four uprights. Each upright has a guide plate opening, and the double-layer support is installed between the outward-facing sides of two uprights.

[0006] Furthermore, two sets of surrounding panels are installed between the periphery of the four uprights, with the two sets of surrounding panels distributed at the upper and lower middle parts of the uprights.

[0007] Furthermore, the double-layer support includes a strip fixed to one side of the upright plate, a side plate fixed on the strip, and two sets of adjustment holes on the side plate. Two sets of support plates are locked and fixed between the opposite side plates by screws passing through the adjustment holes. The counter-push cylinder is installed on the corresponding support plate.

[0008] Furthermore, one of the outermost upright plates is hinged with two sets of long plates, which are located between two sets of surrounding plates, and multiple connecting columns are fixed between the long plates. The other outermost upright plate is fixed with a latch plate, which is L-shaped and has an opening at the top. A latch plate that can extend into the opening is hinged on the inner wall. Both upright plates and the guide plate have a plate release opening located between the two sets of surrounding plates on the same side.

[0009] Furthermore, the lifting assembly includes an upper lifting cylinder installed at the bottom of the platform and multiple guide rods passing through it. The piston rod of the upper lifting cylinder passes through the platform and is fixed at its top end with an ejector cylinder. The piston rod of the ejector cylinder is connected to the piston rod of the upper lifting cylinder, and the top of the ejector cylinder is fixed to the ejector plate.

[0010] Furthermore, a limit assembly is fixed on the inner side of the double-chain conveyor. The limit assembly includes a horizontal plate, on which a mounting plate is fixed by screws. A side plate is also fixed by screws on the mounting plate. A push cylinder is installed on one side of the side plate. The piston rod of the push cylinder is fixed to a push plate. Both the mounting plate and the side plate have waist holes.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The conveying device for the outer shell cover uses a stacking component to centrally stack the covers, a lifting component to automatically separate individual covers, a double-chain conveyor to transport them in an orderly manner, and a transfer component to complete the process connection. The entire process does not require frequent manual operation, reducing labor intensity and labor costs. The baffle, side baffle, and limit baffle components work together to achieve multiple positioning during the cover conveying process, reducing offset errors, avoiding assembly failures caused by cover position deviations, and improving the product qualification rate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-7This embodiment provides a conveying device for a housing cover, including a platform 1. A double-chain conveyor 2 for linear conveying of the cover is mounted on the platform 1. Through double-chain transmission, the conveying power is stable, ensuring the cover moves at a uniform speed along a preset path and reducing deviation during conveying. A baffle 3 and a transfer assembly 6, both located at the tail end of the double-chain conveyor 2, are fixed on the platform 1. These components can accurately transfer the cover, positioned at the tail end of the double-chain conveyor 2, to the assembly station, achieving automated connection between conveying and assembly processes, reducing manual intervention. The baffle prevents excessive movement of the cover, ensuring accurate delivery of the cover to the conveying endpoint. Positioning provides a stable workstation for subsequent transfer processes. Side guards 7 are also fixed on the platform 1, distributed on both sides of the double-chain conveyor 2. The side guards limit the offset of the cover during the conveying process, prevent the cover from falling off the sides of the conveyor, and ensure the safety and orderliness of the conveying process. Limiting components 4 are installed on the inner side of the double-chain conveyor 2. Stacking components 5 are fixed on the platform 1 at the head end of the double-chain conveyor 2 and transfer components 6 are fixed on the platform 1 at the tail end of the double-chain conveyor 2. The limiting components can block the cover on the double-chain conveyor, playing a role in limiting and waiting. At the same time, in conjunction with the transfer components, it can be moved to the pressing position in the subsequent process.

[0023] like Figure 2 , 3 5 and 6, the stacking assembly 5 includes four L-shaped upright plates 51 locked and fixed to the frame 1. The four L-shaped upright plates 51 form a rectangular placement area. All four upright plates 51 are located at guide plate openings on the axis of the side guard 7. The four L-shaped upright plates 51 are symmetrically fixed on both sides of the first end of the double chain conveyor table 2, and the guide plate openings are opened at the position where the upright plates are flush with the side guard 7. The placement area in the upright plates provides a space for accommodating the stacking of the covers. The rectangular structure ensures neat stacking. The guide plate openings provide a conveying channel for the lids to be ejected. A strip 561 is fixed to the outward side of each upright plate 51. A side plate 56 is fixed to the strip. An adjustment hole is opened on the side plate 56. Opposite side plates 56 are locked together by screws passing through the adjustment holes. Two sets of support plates 57 are fixed, and the adjustment holes allow the spacing between the two sets of support plates 57 to be adjusted. A counter-push cylinder 58 is installed on the support plate 57. By adjusting the spacing between the support plates, the counter-push cylinder is positioned in an accurate position to support and correct the cover. The piston rod of the upper counter-push cylinder 58 is fixed with a convex counter-push block 59. When the stacked covers are in the placement area, the counter-push cylinder 58 drives the two counter-push blocks 59 to move relative to each other, so that they can pass through the cover and support the stacked covers. The two sets of lower counter-push cylinders correct the separated covers by pushing them left and right when the bottom cover separates from the counter-push block, ensuring that the stacking is neat and avoiding cover displacement that would affect the ejection effect.

[0024] Among them, the bottom of the platform 1 is equipped with an upper lifting cylinder 510 and guide rods 512 passing through both sides of the upper lifting cylinder 510. The top ends of the guide rods 512 are fixed with an ejection plate 513 located below the rectangular placement area. The bottom of the ejection plate 513 is equipped with an ejection cylinder 511. The piston rod of the ejection cylinder 511 is fixed to the piston rod of the upper lifting cylinder 510 through a cylinder joint. When the top cylinder is driven, it drives the ejector cylinder and ejector plate to move synchronously. At the same time, the guide rod improves the stability of the ejector plate's lifting and lowering, so that the ejector plate is positioned between the two lower opposing cylinders 58. Then the ejector cylinder runs, causing the ejector plate to come into contact with the bottom cover. Then the two upper opposing cylinders drive the opposing blocks to pull away, and the ejector cylinder retracts, so that the bottom cover is positioned between the two lower opposing cylinders and is corrected. At the same time, the upper opposing cylinder drives the opposing blocks to push out and extend to the bottom of the cover for support again. Then the top cylinder retracts, so that the cover just falls on the double chain conveyor table, completing the material feeding and correction, and realizing the orderly separation and conveying connection of individual covers.

[0025] In addition, the upper and lower middle parts of the four uprights 51 are all fixed with surrounding panels 514. Each group of surrounding panels consists of four panels, two long and two short, which improves the overall rigidity of the uprights.

[0026] like Figure 2 As shown in the direction, on the left-hand upright plate 51, two sets of long plates 52 are fixed by hinges between two sets of surrounding plates 514. Multiple connecting posts 53 are fixed between the long plates 52, forming a door frame between the two long plates and the connecting posts. The door frame can be opened outwards. On the right-hand upright plate 51, an L-shaped latch plate 54 is fixed in the middle of the rightmost connecting post. The top of the latch plate 54 has an opening, and the inner wall is hinged with a latch plate 55 that can extend into the opening to block one of the connecting posts 53. When the door frame is closed, the latch plate can block the door frame and prevent it from opening freely. Both sets of upright plates 51 and the guide plate have a plate opening on the same side. The long plates 52 can be flipped open and closed with the connecting posts, which is convenient for maintenance and facilitates manual or mechanical replenishment of the stacked cover with the plate opening. The latch plate 55 works with the latch plate to limit the door frame formed by the combination of long plates and connecting posts, and to lock the door frame formed by the long plates and connecting posts.

[0027] like Figure 4The limiting assembly 4 includes a horizontal plate 41 fixed inside the double-chain conveyor table 2. The horizontal plate has a waist hole, and a mounting plate 42 is fixed to the horizontal plate by screws passing through the waist hole. A side plate 43 is fixed to the mounting plate 42 by screws, and the side plate 43 also has a waist hole, through which screws are also fixed. A push cylinder 44 is mounted on the side of the side plate 43, and a push plate 45 is fixed to the piston rod of the push cylinder 44. When the first set of covers is moved to the bottom of the transfer assembly to await transfer, and the second set is moving, until the second set is above the push plate, the push cylinder 44 drives the push plate 45 to extend from the side during the transfer process, abutting against the side of the cover. This, in conjunction with the side stop, forms a limiting position and also prevents lateral movement. The waist hole design allows adjustment of the relative position of the mounting plate 42 and the side plate 43, thereby adjusting the position of the push cylinder.

[0028] The working principle of the above embodiments is as follows:

[0029] Four L-shaped uprights form a rectangular placement area at the head of the double-chain conveyor for stacking multiple covers. The side rails are flush with the uprights, which also have guide openings to provide a channel for the covers to be removed. Two sets of upper counter-push cylinders drive convex-shaped counter-push blocks to move relative to each other, passing through the through-holes or edge structures of the stacked covers to support them. Two sets of lower counter-push cylinders push left and right to perform lateral correction after the bottom cover is ejected, ensuring its centered position without tilting. The upper push cylinder drives the ejector plate to rise below the bottom cover, while the guide rod ensures smooth lifting. The ejector cylinder then actuates, ejecting the cover. The bottom cover is gently pushed upwards to detach from the stack. At this time, the upper push block is pulled out, releasing the support for the cover. The push cylinder retracts, placing the bottom cover between the lower push cylinders. The lower push cylinders push to complete the lateral correction. After correction, the upper push cylinder extends its push block again to support the remaining stacked covers. The upper push cylinder retracts as a whole, allowing the separated individual covers to fall smoothly onto the double-chain conveyor, completing the unloading. The left vertical plate has a flip-up door frame, which consists of a long plate and connecting columns. It is opened and closed by hinges. The right side has a latch plate and a locking plate to form a mechanical lock, locking the door frame when closed. To prevent accidental opening, a release port is provided for easy manual or robotic arm replenishment of the covers. The double-chain conveyor uses a double-chain drive, ensuring stable power and uniform movement of the covers along the preset path, reducing vibration and deviation. Side guards distributed on both sides of the conveyor limit the lateral movement of the covers, preventing them from falling and ensuring orderly conveying. The limiting assembly is installed inside the double-chain conveyor and includes an adjustable horizontal plate, mounting plate, side plate, and push cylinder. The waist hole design allows adjustment of the lateral and longitudinal positions of the push cylinder to accommodate different cover sizes. The current set of covers has reached the end and is waiting for transfer; subsequent covers will proceed to... When the designated position is reached, the push cylinder drives the push plate to extend from the side and abut against the side wall of the cover, forming a three-point limit with the side guard to prevent it from shaking or shifting during the waiting transfer process, thus achieving precise positioning in the pre-waiting state. The baffle is fixed at the tail end of the double chain conveyor. When the cover is conveyed to the end, it is blocked by the baffle, achieving precise axial positioning and providing a stable reference for transfer. The transfer component is set up above the tail end of the conveyor, grabbing or pushing the positioned cover and accurately transferring it to the downstream pressing or other assembly station, achieving seamless connection between the conveying and assembly processes and greatly reducing manual intervention.
