Cover plate assembly equipment

Abstract

This invention discloses a cover plate assembly equipment, including a frame and an assembly line module. The assembly line module includes an assembly component and a conveyor belt. The assembly component includes a first platform, a second platform, and a first lifting mechanism. The second platform is located above the first platform to support a carrier. A first support column is provided on the side of the first platform facing the second platform to support the cover plate. The first lifting mechanism drives the first platform and the second platform to rise and fall. The length of the first support column is greater than the distance between the first platform and the second platform. When the carrier moves to above the second platform via the conveyor belt, the first lifting mechanism drives the second platform to rise until it supports the carrier. The cover plate is placed on the first support column, and the first lifting mechanism drives the first platform to fall until the cover plate lands on the carrier, completing the assembly. Because the cover plate is supported by the first support column, it can fall smoothly during the assembly process without impacting or colliding with the carrier, resulting in better product quality.

Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, and more particularly to a cover plate assembly equipment. Background Technology

[0002] The introduction of the new product SiPlets in recent years requires the assembly of the cover plate and the carrier at the SMT (Surface Mount Technology) station, according to the requirements of its process flow. This is the cover plate assembly process, which ensures that the panel position is fixed and there is no lifting, thereby improving the accuracy and yield at the P&P placement station.

[0003] In existing technologies, most cover plate assembly is done manually. Workers must manually remove the cover plates to the SMT station, then assemble them one by one from the product carriers, scanning the barcodes to pass through the station. Finally, the assembled products are placed one by one into the track behind the SMT station, flowing to the next station. This entire process requires full human control and is highly susceptible to the following problems:

[0004] 1. Manual assembly requires a lot of manpower and is inefficient.

[0005] 2. There is a risk of human error, such as contact with solder balls causing defects or reversed assembly of the cover plate.

[0006] 3. Manual operation by workers carries a high risk and may be accompanied by repetitive labor due to poor assembly. Fatigue-related work is more likely to lead to safety issues.

[0007] In response, some automatic cover plate installation equipment has been developed, but there are still some problems with the installation of covers and carriers. For example, the overall equipment structure is complex, and the components used for positioning and assembly are not well integrated; or the covers and carriers are easily affected by impacts during assembly, which can affect the quality of the product.

[0008] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Summary of the Invention

[0009] The purpose of this invention is to provide a cover plate assembly device with a simple structure that can automatically assemble cover plates, and the quality of the product will not be affected by impact between the carrier and the cover plate.

[0010] The technical solution provided by this invention is as follows:

[0011] A cover plate assembly device, comprising:

[0012] A frame and a production line module mounted on the frame;

[0013] The assembly line module includes an assembly component and two parallel conveyor belts located on both sides of the assembly component.

[0014] The assembly assembly includes a first platform, a second platform, and a first lifting mechanism; the second platform is located above the first platform and is used to support the carrier; the first platform has at least two first support columns on the side facing the second platform to support the cover plate; the first lifting mechanism is used to drive the first platform and the second platform to rise and fall together.

[0015] Wherein, the length of the first support column is greater than the distance between the first platform and the second platform;

[0016] First, the second platform and the first support column are located below the conveyor belt. When the vehicle is conveyed to the top of the second platform via the conveyor belt, the conveyor belt stops running. At the same time, the first lifting mechanism drives the first platform and the second platform to rise until the second platform supports the vehicle. Then, the cover plate is placed on the first support column. Next, the first lifting mechanism drives the first platform and the second platform to descend. The vehicle first falls onto the conveyor belt until the cover plate on the first support column falls onto the vehicle and the assembly is completed. The conveyor belt then restarts operation.

[0017] In some embodiments, the top of the first support column is provided with a first positioning post for positioning the cover plate; and

[0018] The first platform surrounds the second platform, or the second platform is located on the side away from the first platform, and is provided with at least two second positioning posts for positioning the vehicle.

[0019] In some embodiments, each of the second positioning posts is provided with a third positioning post at its top for positioning the cover plate.

[0020] In some embodiments, the first lifting mechanism includes a fixed platform and a linear motor;

[0021] The fixed platform is mounted on the frame and located below the first platform;

[0022] The linear motor is fixed to the side of the fixed platform away from the first platform, and the drive end of the linear motor passes through the fixed platform and is fixedly connected to the first platform to drive the first platform to rise and fall.

[0023] The first platform is provided with at least one guide post facing the fixed platform, and the fixed platform is provided with a guide hole through which the guide post passes, so as to guide the first platform to move up and down along the length direction of the guide post.

[0024] In some embodiments, a limiting plate extends from the edge of the first platform toward the fixed platform, the limiting plate having a limiting groove, and the limiting groove having a first end and a second end opposite to each other in the lifting direction of the first platform; and

[0025] The fixed platform edge is provided with a limiting piece corresponding to the limiting groove, and the limiting piece can be selectively abutted against the first end and the second end;

[0026] When the limiting piece abuts against the first end, the top of the first support column is flush with the upper surface of the conveyor belt, which is suitable for the cover plate to fall onto the carrier; when the limiting piece abuts against the second end, the side of the second platform away from the first platform is flush with the upper surface of the conveyor belt, which is suitable for the second platform to support the carrier, or for the carrier to fall onto the conveyor belt.

[0027] In some embodiments, the cover plate assembly equipment further includes:

[0028] The first storage bin is used to store the cover plates to be assembled;

[0029] A feeding assembly is used to remove the cover plate from the first storage bin and place it on the first support column.

[0030] In some embodiments, the edge of the cover plate has a slot, and the inner sidewall of the first storage box is provided with a positioning protrusion that matches the slot on the cover plate to determine the placement direction of the cover plate.

[0031] and / or

[0032] The feeding assembly includes a first fixed frame, a moving mechanism, and grippers;

[0033] The first fixed frame is fixed to the machine frame, and the moving mechanism is fixed to the first fixed frame to drive the gripper to move. The gripper is used to grip the cover plate in the first storage box.

[0034] The gripper is equipped with a contact sensor facing the cover plate to confirm whether the cover plate is securely clamped.

[0035] In some embodiments, the cover plate assembly equipment further includes:

[0036] The second storage bin is used to store the assembled carrier and cover plate;

[0037] The third lifting mechanism is used to lift the second storage box, so that the assembled carriers and covers stored in the second storage box are sequentially transported to the next production line through the assembly line module according to the order in which they entered the second storage box.

[0038] In some embodiments, the distance between the two conveyor belts is adjustable.

[0039] In some embodiments, the cover plate assembly equipment further includes:

[0040] A stop block located above the conveyor belt;

[0041] There is a pre-set gap between the stop block and the conveyor belt. If the assembled vehicle and cover plate warp or the height exceeds the size of the gap between the stop block and the conveyor belt, the stop block restricts the assembled vehicle and cover plate from being sent out by the conveyor belt.

[0042] and / or

[0043] A barcode scanner located above the assembly components;

[0044] Both the vehicle and the cover are equipped with QR codes or barcodes for identification purposes, and the scanning device is used to scan the QR codes or barcodes on the assembled vehicle and the cover.

[0045] The technical effects of this invention are as follows:

[0046] 1. By setting up a production line module, the cover plate assembly equipment can automatically collect the carrier from the previous process via conveyor belts located on both sides of the assembly components, and send the assembled carrier and cover plate to the next production line. Simultaneously, this patent incorporates a first lifting mechanism that can drive the first and second platforms to rise and fall, thereby placing the carrier on the second platform and the cover plate on the first support column sequentially onto the conveyor belt, thus completing the assembly. This method is quick, convenient, and highly integrated. Furthermore, because the cover plate is supported by the first support column, it descends smoothly during assembly, preventing impact or collision with the carrier, resulting in better product quality.

[0047] 2. By opening a slot in the cover plate and setting a positioning boss that matches the slot in the first storage box, the placement position of the cover plate in the first storage box is determined. In this way, when the feeding assembly places the cover plate on the first support column, it can be ensured that the direction of the cover plate is correct, thereby effectively avoiding the situation where the cover plate is assembled in reverse.

[0048] 3. Because the assembly speed of the cover plate is relatively fast compared to subsequent processes, in order not to affect the output of this equipment and the equipment in the preceding processes, this invention provides a second storage bin to temporarily store the assembled cover plates and carriers. However, since the carriers should not be left for too long after soldering, this invention also provides a third lifting mechanism that can drive the second storage bin to rise and fall, so that the assembled cover plates and carriers placed in the second storage bin first can be sent out through the production line module first, thereby ensuring product quality.

[0066] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0067] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0068] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, to facilitate understanding, in some figures, only one of components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0069] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0070] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0071] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of the invention are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the descriptions of the positions of these components change, these directional indications also change accordingly.

[0072] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0073] According to a specific embodiment provided by the present invention, see [link to specific embodiment]. Figures 1 to 9 A cover plate assembly device may specifically include a frame 100 and a production line module 300 mounted on the frame 100. The production line module 300 includes an assembly assembly 200 and conveyor belts 360 located on both sides of the assembly assembly. The assembly assembly 200 includes a first platform 210, a second platform 220, and a first lifting mechanism 230. The second platform 220 is located above the first platform 210 and is used to support a carrier 610. The first platform 210 has at least two first support columns 211 on the side facing the second platform 220 to support the cover plate 620. The first lifting mechanism 230 is used to lift the first platform 210 and the second platform 220 together. The length of the first support columns 211 should be greater than the distance between the first platform 210 and the second platform 220 so that the cover plate 620 is located a distance above the carrier 610.

[0074] It is worth noting that, in the early stages of assembly, the second platform 220 and the first support column 211 should be located below the conveyor belt 360. When the carrier 610 is conveyed to the top of the second platform 220 via the conveyor belt 360, the conveyor belt 360 stops running. Simultaneously, the first lifting mechanism 230 lifts the first platform 210 and the second platform 220 together until the second platform 220 supports the carrier 610. Subsequently, the cover plate 620 is placed on the first support column 211. Then, the first lifting mechanism 230 lowers the first platform 210 and the second platform 220 together. The carrier 610 first falls onto the conveyor belt 360 until the cover plate 620 on the first support column 211 falls onto the carrier 610, completing the assembly. The conveyor belt 360 then resumes operation.

[0075] In this embodiment, the second platform 220 and the first support column 211 are positioned below the conveyor belt 360 in the early stage of assembly. The purpose is to avoid the carrier 610 from colliding with the first support column 211 and damaging the carrier when it is conveyed by the conveyor belt 360 to the position corresponding to the second platform 220.

[0076] In this embodiment, the assembly line module 300 can be functionally divided into a feeding area 310, an assembly area 320, and a discharge area 330. Specifically, two conveyor belts 360 extend along the conveying direction and are arranged in parallel. At this time, the assembly component 200 and the portions of the two conveyor belts 360 corresponding to the assembly component 200 together form the assembly area of ​​the assembly line module 300. The portion of the two conveyor belts 360 in the conveying direction in front of the assembly component 200 is the feeding area 310, and the portion of the two conveyor belts 360 in the conveying direction in rear of the assembly component 200 is the discharge area 330. The carrier 610 from the previous process is conveyed from the feeding area 310 to the second platform 220 located in the assembly area 320, and the assembled carrier 610 and cover plate 620 in the assembly area 320 are sent out to the discharge area 330.

[0077] This embodiment, by setting up a production line module 300, enables the cover plate assembly equipment to automatically collect the carrier 610 from the previous process via a conveyor belt 360, and send the assembled carrier 610 and cover plate 620 to the next production line. Simultaneously, this embodiment, by setting up a first lifting mechanism 230, can drive the first platform 210 and the second platform 220 to rise and fall, so that the carrier 610 on the second platform 220 first falls onto the conveyor belt 360, and the cover plate 620 on the first support column 211 then falls onto the carrier 610, completing the assembly. Thus, the cover plate assembly equipment provided in this embodiment can replace the original manual assembly, significantly improving product output efficiency while solving problems such as the operational risks of repetitive manual fatigue work and the risk of accidental contact with solder on the product by manual operation, thereby improving product yield. Moreover, the use of automated machine assembly can effectively reduce labor costs.

[0078] Furthermore, in this embodiment, the cover plate 620 is supported by the first support column 211. Before assembly, the cover plate 620 can descend smoothly with the first platform 210 without impacting or colliding with the carrier 610, resulting in better product quality.

[0079] Specifically, see Figure 7 and Figure 8 Both the carrier 610 and the cover plate 620 are equipped with magnets 630, and the positions of the magnets 630 on the carrier 610 and the cover plate 620 correspond one-to-one. The carrier 610 and the cover plate 620 are fixedly connected by magnetic adsorption. Compared with the PIN positioning assembly method commonly used in the industry, this setup provides a more stable and convenient installation, ensuring the quality of the SMT process and preventing abnormalities in SMT placement and other workstations caused by product deformation, warping, or misalignment.

[0080] Specifically, see Figure 2 and Figure 3The first support column 211 has a first positioning column 2111 at its top for positioning the cover plate 620. Simultaneously, the first platform 210 surrounds the second platform 220, or on the side of the second platform 220 away from the first platform 210, and has at least two second positioning columns 213 for positioning the carrier 610. Through the positioning function of the first positioning columns 2111 and the second positioning columns 213, the assembly accuracy of the cover plate 620 and the carrier 610 can be effectively ensured, resulting in a high product yield. Furthermore, in this embodiment, the positioning and rapid installation of the cover plate 620 and the carrier 610 can be achieved solely through the cooperation of the first platform 210, the second platform 220, and the conveyor belt 360. The structure is simple and highly integrated, suitable for mass production, and highly practical.

[0081] Preferably, each of the second positioning posts 213 is also provided with a third positioning post 2131 at its top for positioning the cover plate 620.

[0082] In one specific embodiment, see Figure 2 and Figure 3 The first platform 210 and the second platform 220 are connected by at least two second support columns 212. Specifically, one end of each second support column 212 has a stop, and the other end passes through the first platform 210 and is fixedly connected to the second platform 220. A spring is provided on each second support column 212, and both ends of the spring abut against the sides of the first platform 210 and the second platform 220 that are close to each other. When the carrier 610 is placed on the second platform 220, the second platform 220 and the second support column 212 will descend along the length of the second support column 212 under the weight of the carrier 610. At this time, the spring can provide a certain buffering effect, preventing the second platform 220 from impacting the carrier 610 when carrying it, thereby preventing damage to the PCB components on the carrier 610 and further ensuring product quality.

[0083] Specifically, see Figure 2 and Figure 3 The first lifting mechanism 230 includes a fixed platform 231 and a linear motor 232. The fixed platform 231 is located on the frame 100 and below the first platform 210. The linear motor 232 is fixed to the side of the fixed platform 231 away from the first platform 210, and the drive end of the linear motor 232 passes through the fixed platform 231 and is fixedly connected to the first platform 210 to drive the first platform 210 to lift. The first platform 210 has at least one guide post 214 facing the fixed platform 231, and the fixed platform 231 has a guide hole through which the guide post 214 passes to guide the first platform 210 to lift along the length of the guide post 214.

[0084] To further simplify the operation steps and optimize the structure, please refer to [link / reference]. Figure 9In a preferred embodiment, the tops of the first positioning post 2111 and the third positioning post 2131 are aligned with the upper surface of the conveyor belt 360 of the assembly line module 300 during the initial assembly phase, driven by the first lifting mechanism 230. This allows the carrier 610 in the feeding area 310 to be directly transported to the top of the second platform 220 via the conveyor belt 360. Subsequently, the first lifting mechanism 230 raises the second platform 220 until it is at least aligned with the upper surface of the conveyor belt 360 of the assembly line module 300, ensuring that the second platform 220 can support the carrier 610. At this time, the third positioning post 2131 and the second positioning post 213 pass through the carrier 610 in sequence, with the second positioning post 213 used to position the carrier 610. Next, the cover plate 620 is placed on the first support post 211. At this time, the first positioning post 2111 and the third positioning post 2131 pass through the cover plate 620 to position the cover plate 620. Finally, the first lifting mechanism 230 drives the first platform 210 and the second platform 220 to descend, and the carrier 610 first falls onto the conveyor belt 360 until the tops of the first positioning post 2111 and the third positioning post 2131 are flush with the upper surface of the conveyor belt 360, so that the cover plate 620 falls onto the carrier 610, completing the assembly with the carrier 610.

[0085] Further, see Figure 2 and Figure 3 A limiting plate 215 extends from the edge of the first platform 210 toward the fixed platform 231. The limiting plate 215 is provided with a limiting groove 2152, and the limiting groove 2152 has a first end and a second end opposite to each other in the lifting direction of the first platform 210. At this time, a limiting piece 2311 is provided on the edge of the fixed platform 231 corresponding to the limiting groove 2152. The limiting piece 2311 can be selectively abutted against the first end and the second end of the limiting groove 2152.

[0086] When the limiting piece 2311 abuts against the first end, the top of the first support column 211, namely the top of the first positioning column 2111 and the third positioning column 2131, is flush with the upper surface of the conveyor belt 360 of the assembly line module 300, which is suitable for the cover plate 620 to fall onto the carrier 610; when the limiting piece 2311 abuts against the second end, the side of the second platform 220 away from the first platform 210 is flush with the upper surface of the conveyor belt 360 of the assembly line module 300, which is suitable for the second platform 220 to support the carrier 610 when the first lifting mechanism 230 drives the second platform 220 to rise, or for the carrier 610 to fall onto the conveyor belt 360 when the first lifting mechanism 230 drives the second platform 220 to fall.

[0087] This embodiment limits the movement of the first platform 210 and the second platform 220 by setting a limiting groove 2152 and a limiting piece 2311, so that energy consumption can be minimized while ensuring the assembly function is achieved, thereby realizing green production, reducing costs, and being highly practical and economically efficient.

[0088] Specifically, the limiting groove 2152 can be a groove 621 directly cut on the limiting plate 215, or two limiting blocks 2151 can be set on the limiting plate 215 to form a limiting groove 2152 between the two limiting blocks 2151. These are all within the protection scope of the present invention and will not be described in detail here.

[0089] In one specific embodiment, see Figure 1 , Figure 4 and Figure 6 The cover plate assembly equipment may also include a first storage box 410 and a feeding component 420. The first storage box 410 is used to store the cover plate 620 to be assembled, and the feeding component 420 is used to take the cover plate 620 out of the first storage box 410 and place it on the first support column 211.

[0090] Preferably, see Figure 4 and Figure 7 The cover plate 620 has a slot 621 on its edge, and the inner wall of the first storage bin 410 has a positioning protrusion 411 that matches the slot 621 on the cover plate 620. This protrusion determines the placement direction of the cover plate 620, ensuring that the cover plate 620 is placed in the first storage bin 410 in a preset orientation. Thus, when the feeding assembly 420 places the cover plate 620 onto the first platform 210, the orientation of the cover plate 620 is correct, effectively preventing the cover plate 620 from being assembled in reverse.

[0091] Further, see Figure 6 The feeding assembly 420 includes a first fixed frame 421, a moving mechanism 422 and a gripper 423. The first fixed frame 421 is fixed to the frame 100, and the moving mechanism 422 is fixed to the first fixed frame 421 to drive the gripper 423 to move. The gripper 423 is used to grip the cover plate 620 in the first storage box 410.

[0092] In this embodiment, the cover plate 620 is conveyed by a gripper 423. Compared with the general suction nozzle type fixed transport, the gripper 423 has a longer lifespan, higher stability, and more reliable gripping, which can meet the production requirements. To further optimize the structural settings and speed up the product process, the feeding component 420 should move in a reciprocating linear motion between the first storage box 410 and the assembly component 200.

[0093] Specifically, the moving mechanism 422 can be a linear motor 232, the drive end of which is fixedly connected to the gripper 423. Alternatively, the moving mechanism 422 may include a rotary motor, a screw, and a slide. In this case, the drive end of the rotary motor is fixed to the screw, the slide and gripper 423 are fixedly connected, and the slide has a threaded hole that mates with the screw. The first fixed frame 421 has a guide structure to guide the movement direction of the slide. Thus, when the rotary motor rotates, the screw can drive the slide to move along the direction of the guide structure, thereby moving the gripper 423.

[0094] In actual production, see Figure 6 A second lifting mechanism 430 can also be provided between the slide and the gripper 423, enabling the gripper 423 to be lifted and lowered to better transport the cover plate 620 in the first storage box 410 to the assembly assembly 200. In this case, the second lifting mechanism 430 can be a linear motor or have a structure including a rotary motor, a screw and a slide, which will not be described in detail here, but are all within the protection scope of this invention.

[0095] Of course, a second lifting mechanism 430 can also be provided between the first storage bin 410 and the frame 100 to drive the first storage bin 410 to lift and lower, making it convenient to clamp and retrieve the cover plate 620. Correspondingly, the second lifting mechanism 430 can be a linear motor 232, or it can have a structure including a rotary motor, a screw and a slide, which will not be described in detail here, and are all within the protection scope of this invention.

[0096] Furthermore, the gripper 423 is equipped with a contact sensor facing the cover plate 620 to confirm whether the cover plate 620 is clamped securely. Only after confirming that the cover plate 620 is clamped flat and properly clamped will the gripper 423 remove the cover plate 620 from the first storage box 410 according to a preset program.

[0097] Furthermore, see Figure 1 and Figure 5 Because the assembly speed of the cover plate is relatively fast compared to subsequent processes, in order not to affect the output of this equipment and the preceding process equipment, this invention provides a second storage bin 510 to temporarily store the assembled cover plate 620 and carrier 610. However, since the carrier 610 should not be left for too long after soldering, this invention also provides a third lifting mechanism 520 that can lift the second storage bin 510, so that the assembled cover plate 620 and carrier 610 placed in the second storage bin 510 can be sent out through the production line module 300 first, thereby ensuring product quality.

[0098] Specifically, see Figure 5The second storage bin 510 is provided with several sets of rollers 511 along the height direction, and each set of rollers 511 includes four rollers 511, which are arranged in pairs on the same height layer of the two opposite inner side walls of the second storage bin 510. At this time, a placement layer is formed between the two sets of rollers 511 located on the same height layer, which can accommodate the assembled carrier 610 and cover plate 620.

[0099] In actual production, the third lifting mechanism 520 can be a linear motor or a structure including a rotary motor, a screw and a slide, which will not be elaborated here, and are all within the protection scope of this invention.

[0100] At this time, the assembly line module 300 can be equipped with a push-pull component in both the assembly area 320 and the discharge area 330. The push-pull component in the assembly area 320 is used to push the assembled carrier 610 and cover plate 620 into the second storage box 510, while the push-pull component in the discharge area 330 is used to remove the assembled carrier 610 and cover plate 620 from the second storage box 510.

[0101] Preferably, a conveyor platform 340 is provided between the two conveyor belts 360 and at positions corresponding to the feeding area 310 and the discharging area 330, and the conveyor platform 340 is composed of several rollers.

[0102] Furthermore, the distance between the two conveyor belts 360 is adjustable to accommodate carriers 610 and cover plates 620 of different sizes, improving the versatility and applicability of the cover plate assembly equipment. Specifically, the adjustable range of the distance between the two conveyor belts 360 is 100mm to 350mm to accommodate carriers 610 with dimensions L*W=100*100mm to 350*350mm.

[0103] Of course, in actual production, the adjustment range of the distance between the two flanges 350 can be flexibly set according to the actual situation. This embodiment only lists one feasible solution and does not limit it. All of them are within the protection scope of this invention.

[0104] Specifically, see Figure 9 Two conveyor belts 360 are respectively fixed to two second fixed frames 350, and at least one second fixed frame 350 is connected to at least one guide rail 370 fixed to the frame 100. By changing the position of the second fixed frame 350 relative to the guide rail 370, the distance between the two second fixed frames 350 can be adjusted, thereby adjusting the distance between the two conveyor belts 360. Of course, in actual production, a linear motor can also be set to drive the second fixed frame 350 to reciprocate on the guide rail 370, which is more conducive to adjusting the distance between the two conveyor belts 360 and has strong practicality.

[0105] Specifically, the cover plate assembly equipment also includes a stop block located above the conveyor belt 360. This stop block is preferably positioned above the conveyor belt 360 in the discharge area 330 near the assembly area 320, with a pre-set gap between it and the conveyor belt 360. If the assembled carrier 610 and cover plate 620 meet quality standards, they can pass directly through this gap and be conveyed to the second storage bin 510. Conversely, if the assembled carrier 610 and cover plate 620 have quality problems such as warping or height exceeding the gap size, the stop block will block the assembled carrier 610 and cover plate 620 to restrict their movement along the assembly line module 300, ensuring that the quality of the cover plate assembly meets production requirements.

[0106] Preferably, the stop block is equipped with a sensor, which is electrically connected to the central control system of the cover plate assembly equipment. Simultaneously, the central control system of the cover plate assembly equipment is electrically connected to an alarm. When the assembled carrier 610 and cover plate 620 contact the stop block, the sensor sends information to the central control system. The central control system receives the information and controls the alarm to sound an alarm, facilitating timely recall of substandard products by the user. Specifically, the cover plate assembly equipment also includes a barcode scanning device. Both the carrier 610 and cover plate 620 should have QR codes or barcodes for identification. The barcode scanning device is used to scan the QR codes or barcodes on the assembled carrier 610 and cover plate 620. Preferably, a Keyence SR2000 barcode reader is used.

[0107] This embodiment ensures no missed scans or incorrect scans by automatically scanning through stations, which is beneficial for subsequent review of product history information and enables effective management of products and related information.

[0108] The specific operation process of the cover plate assembly equipment provided by this invention is as follows:

[0109] First, the first lifting mechanism 230 lowers the first platform 210 until the tops of the first positioning post 2111 and the third positioning post 2131 of the first platform 210 are level with or slightly lower than the conveyor belt 360. Then, the carrier 610 is moved above the second platform 220 by the conveyor belt 360. Next, the first lifting mechanism 230 raises the second platform 220 to a position level with the conveyor belt 360, so that the second platform 220 supports the carrier 610. During this process, the third positioning post 2131 and the second positioning post 213 pass through the carrier 610 in sequence, and the second positioning post 213 is used to position the carrier 610. Afterwards, the gripper 423 on the feeding assembly 420 moves into the first storage bin 410 and grabs the cover plate 620 stored therein, placing it on the first support post 211 of the first platform 210. Subsequently, the first positioning post 2111 and the third positioning post 2131 pass through the cover plate 620 to position it. Next, the first lifting mechanism 230 lowers the first platform 210 and the second platform 220. The carrier 610 first lands on the conveyor belt 360, and simultaneously, the cover plate 620, placed on the first support post 211 of the first platform 210, descends together until it lands on the carrier 610, where it is magnetically secured, completing the assembly. After the assembled carrier 610 and cover plate 620 are scanned by a barcode scanner, their quality is confirmed by a stop. If the assembled carrier 610 and cover plate 620 fail to pass through the preset gap between the stop and the assembly line module 300, the product quality is considered unqualified. Conversely, if the assembled carrier 610 and cover plate 620 pass through the preset gap between the stop and the assembly line module 300, the product quality is considered qualified. Finally, the assembled carrier 610 and cover plate 620, whose product quality has been confirmed to be up to standard, will be placed in the second storage box 510 until they are sent to the next process.

[0110] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0111] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
