Description

Technical Field

[0001] This invention relates to the field of processing equipment, and in particular to a fully automatic laser engraving processing equipment. Background Technology

[0002] In the field of electronic component manufacturing, precision products, such as mobile phone casings (hereinafter referred to as "products"), often require laser engraving at different locations on their surface during the production process to form baselines to assist in the assembly of other components. This type of processing requires completion on both the front and back sides of the product and demands high precision and consistency.

[0003] Currently, laser engraving processes typically employ a tray-based system. Specifically, products are pre-placed in specially designed trays on the production line. This design not only facilitates batch transfers but also effectively prevents surface damage from collisions or friction during transport. A standard tray can usually hold multiple products, maximizing production efficiency.

[0004] However, existing processes face a key challenge in achieving fully automated laser engraving: the gripping mechanism of the processing equipment typically cannot handle both the tray and the products simultaneously, making tray storage and retrieval problematic. To address this, the industry currently employs a manual-assisted transitional solution: workers first remove the products from the tray one by one and stack them on a dedicated fixture of the processing equipment, which then performs laser engraving on each product sequentially. While this solution solves the tray storage problem, manual transfer requires individual handling, preventing batch processing, increasing processing time, and reducing efficiency, thus becoming a bottleneck restricting overall production efficiency. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a fully automatic laser engraving processing equipment to solve the problem of how to automatically feed and process products on the existing material tray.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A fully automatic laser engraving processing equipment feeding mechanism includes a feeding mechanism, a conveying mechanism, a laser engraving mechanism, and a discharging mechanism. The material tray has a device cavity for assembling and positioning products. The feeding mechanism includes a first conveying section having a first infeed end and a first discharge end, two first receiving and dispatching sections thereon for stacking material trays and transferring single material trays relative to the first conveying section, and a first transfer section for acquiring products from the feeding tray of the first conveying section. One of the first receiving and dispatching sections is located near the first infeed end to output a single material tray with products to the first infeed end, and the other first receiving and dispatching section is located near the first discharge end to input an empty material tray from the first discharge end. The conveying mechanism is used to move products and has an infeed position for the first transfer section to transfer products to it. The laser engraving mechanism is used to perform laser engraving processing and inspection on the products on the conveying mechanism. The discharging mechanism is used to transfer the products on the conveying mechanism to an empty material tray.

[0007] Furthermore, the first conveying unit also includes a feeding position located between the first feeding end and the first discharging end; both first receiving and dispatching units include a first material stacking platform with a first material stacking cavity on the inner side, a first lifting part disposed on the first material stacking platform and used to support the bottommost bottom material tray, and a first material supporting part disposed on both sides of the first material stacking cavity and used to support the material tray, wherein the first feeding end and the first discharging end are respectively located in the two first material stacking cavities.

[0008] Furthermore, the first stacking cavity has a first moving cavity section that allows the first conveying part to move the material tray and a first stacking cavity section that stacks the material tray vertically and blocks the material tray horizontally; the first supporting part has a first support plate that can extend and retract toward the first stacking cavity section to support the material tray after the first lifting part supports the material tray, and a space for the material tray to move is separated between the first support plate and the first conveying part; the first lifting part is used to move down after the first supporting part holds the material tray so that the bottom material tray is transferred to the first feeding end or to push the empty material tray on the first discharging end upward until the second support plate holds the empty material tray.

[0009] Furthermore, the conveying mechanism has a conveying surface that moves in a horizontal direction, and the conveying surface has a discharge position and a feed position; the conveying surface also has a flipping position located between the feed position and the discharge position, a first laser engraving position located between the feed position and the flipping position, and a second laser engraving position located between the flipping position and the discharge position, and the flipping position is provided with a flipping part for flipping the product.

[0010] Furthermore, the conveying mechanism includes a first conveying frame, the conveying surface is disposed on the first conveying frame, and the feeding position, the flipping position and the discharging position are each provided with two guide parts connected to the first conveying frame, and there is a guide space between the two guide parts at each position for the product to move on the conveying surface along a conveying direction of the conveying mechanism.

[0011] Furthermore, the guide portion includes a connecting rod connected to the first conveyor frame and extending toward the conveying surface, a guide rod connected to the connecting rod and having an adjustable angle, and an end rod connected to the end of the guide rod away from the discharge position and having an adjustable angle. The end rod is gradually narrowed toward the side away from the discharge position, and the guide space is formed between the two guide rods and the end rod at each position.

[0012] Furthermore, the flipping part has a positioning block that can be flipped 180 degrees from an initial position to a completed position along the conveying direction. The positioning block has a positioning cavity that is flush with the conveying surface when the positioning block is in the initial or completed position, allowing a part of the product to be inserted therein while the other part is on the conveying surface. The flipping part includes a mounting cavity recessed on the conveying surface, a rotating shaft that spans the conveying surface and is rotatably connected to the mounting cavity, and a first driving member that drives the rotating shaft to rotate axially. The positioning block is connected to the rotating shaft, and a limiting strip is provided in the mounting cavity for the positioning block to be in the initial or completed position when supported thereon.

[0013] Furthermore, the guide portion is provided on the conveying surface between the first laser engraving position and the flipping part, and between the second laser engraving position and the flipping part, both facing the positioning cavity along the conveying direction.

[0014] Furthermore, the conveying mechanism also includes a waste gas recovery unit for absorbing fumes during laser engraving of products at the first and second laser engraving positions.

[0015] Furthermore, the feeding mechanism includes a second conveying section having a second feeding end and a second discharging end, two second receiving and dispatching sections thereon for stacking trays and transferring a single tray relative to the second conveying section, and a second transfer section for transferring products from the conveying mechanism to an empty tray. One of the second receiving and dispatching sections is close to the second feeding end to output a single empty tray, and the other second receiving and dispatching section is close to the second discharging end to input a tray containing products. The second conveying section also includes a receiving position located between the second feeding end and the second discharging end. Both second receiving and dispatching sections include a second stacking platform with a second stacking cavity on its inner side, a second lifting section disposed on the second stacking platform for supporting the bottom tray, and a second supporting section disposed on both sides of the second stacking cavity for supporting the tray. The second feeding end and the second discharging end are respectively located in the two second stacking cavities.

Detailed Implementation

[0018] The invention will now be further described with reference to the accompanying drawings.

[0019] Please see Figure 1 and Figure 2 The fully automatic laser engraving equipment of the present invention includes a material tray 1, a feeding mechanism 2, a conveying mechanism 3, a laser engraving mechanism 4, and a discharging mechanism 5.

[0020] Please see Figure 3The tray 1 is rectangular, and multiple device cavities 11 for mounting and positioning the product 14 are recessed on the top surface of the tray 1. The device cavities 11 can be arranged in a rectangular array. In one embodiment, the product 14 of the present invention is a mobile phone case, and the mobile phone case is rectangular in shape. Therefore, the device cavities 11 are rectangular and their size is adapted to the product 14 so that the product 14 can be mounted in the device cavities 11. In order to facilitate the picking up of the product 14, any two adjacent device cavities 11 along the row or column direction are interconnected to form a picking groove 12, so as to facilitate the picking up or placing of the product 14. Grooves are uniformly recessed on each side of the tray 1, and each groove faces outward and upward to facilitate the positioning and gripping of the tray 1 by clamps or robots through the grooves. The tray 1 can be made of plastic. In order to improve the service life of the tray 1, an inner plate 13 is provided corresponding to the contour of the device cavity 11. The inner plate 13 can be made of metal and has an inner cavity corresponding to the device cavity 11. The product 14 is installed in the inner cavity.

[0021] Please see Figures 4 to 9 The feeding mechanism 2 of the present invention includes a first cabinet 21, a first conveying section 22 disposed on the first cabinet 21, two first receiving and dispatching sections 23 thereon for stacking trays 1 and transferring single trays 1 relative to the first conveying section 22, and a first transfer section 24 for acquiring products 14 in the trays 1 of the first conveying section 22. The first conveying section 22 has a first feeding end 221, a feeding position 222, and a first discharging end 223 in sequence. The feeding position 222 is located between the first feeding end 221 and the first discharging end 223. The first conveying section 22 can move the tray 1 from the first feeding end 221 to the feeding position 222 and then continue to move it to the first discharging end 223. One of the first receiving and dispatching sections 23 is located near the first feeding end 221 to output a single tray 1 containing products 14 to the first feeding end 221, and the other first receiving and dispatching section 23 is located near the first discharging end 223 to input an empty tray 1 from the first discharging end 223.

[0022] In this embodiment, the first cabinet 21 is equipped with various electrical devices such as sensors, controllers, air intake sources, and power supplies. The specific configuration is based on the first conveying section 22, etc., and will not be described in detail here. The top of the first cabinet 21 has a rigid, rectangular first base plate 211. The first conveying section 22, the first receiving / dispatching section 23, and the first transfer section 24 are all mounted on the first base plate 211. On both sides of the first base plate 211 along its length, a first receiving chamber is formed by first U-shaped baffles 212 connected to the three sides. The two first receiving chambers are open and connected to each other along their length.

[0023] The first feed end 221 and the first discharge end 223 of the first conveying section 22 extend into the two first receiving cavities, respectively, and the loading position 222 is located outside the two first receiving cavities and between the two first baffles 212. The first conveying section 22 includes a second conveying frame 224, two first transmission parts rotatably connected to the second conveying frame 224, and an eighth driving member installed on the first cabinet 21 or the second conveying frame 224 and driving the two first transmission parts. The second conveying frame 224 includes two first transmission arms 2241 arranged parallel along the longitudinal direction and two first connecting arms 2242 connected to the two first transmission arms 2241 at both ends, and the two first connecting arms 2242 are arranged in parallel. The two ends of the two first transmission arms 2241 extend into the two first receiving cavities, respectively. Both first transmission units include two first transmission wheels 2251 and first transmission toothed belts 2252 wound around the two first transmission wheels 2251. A total of four first transmission wheels 2251 are rotatably connected to both ends of the two first transmission arms 2241 and arranged axially along the width direction, so that the two first transmission toothed belts 2252 are parallel and spaced apart, and each first transmission wheel 2251 is located within the first receiving cavity. The distance between the two first transmission toothed belts 2252 is less than the distance between the material trays 1, so as to support and transport the movement of the material trays 1. It should be noted that the diameter of the first transmission wheel 2251 is equal to the width of the first transmission arm 2241, and its two sides are flush with the sides of the first transmission arm 2241, so that the first transmission arm 2241 is wound around and supported by the first transmission arm 2241. The eighth drive unit is a drive device such as a rotary motor whose output shaft can rotate. The output shaft of the eighth drive unit is connected to a first transmission wheel 2251 of the two sets of first transmission parts so that the two sets of first transmission parts can drive synchronously.

[0024] The eighth driving member drives the first transmission unit by connecting to one of the first transmission wheels 2251 or by a reducer, so that the first transmission toothed belt 2252 can rotate cyclically relative to each of the first transmission wheels 2251. Specifically, the portion of the top of the first transmission toothed belt 2252 located within one of the first receiving chambers is configured as the first feed end 221, the portion of the top of the first transmission toothed belt 2252 located within the other first receiving chamber is configured as the first discharge end 223, and the portion of the top of the first transmission toothed belt 2252 located outside the first receiving chamber and between the first feed end 221 and the first discharge end 223 is configured as the loading position 222. The eighth driving member drives the first transmission unit to move the material tray 1 towards the first discharge end 223 along its length (referring to the length of the first base plate 211) after it has been transferred to the first feed end 221. This length direction is the conveying direction of the first conveying unit 22.

[0025] Two first receiving / dispatching sections 23 are respectively disposed in two first receiving / dispatching cavities. One first receiving / dispatching section 23 with a first feeding end 221 extending inside is defined as a first discharging section 23a, and the other first receiving / dispatching section 23 with a first discharging end 223 extending inside is defined as a first receiving section 23b. The first discharging section 23a and the first receiving section 23b (or the two first receiving / dispatching sections 23) each include a first stacking platform with a first stacking cavity 233 on its inner side, a first lifting section 231 disposed on the first stacking platform for supporting the bottommost bottom tray 1, and a first supporting section 232 disposed on both sides of the first stacking cavity 233 for supporting the tray 1. The first feeding end 221 is located in the first stacking cavity 233 of the first discharging section 23a, and the first discharging end 223 is located in the first stacking cavity 233 of the first receiving section 23b.

[0026] The first base plate 211 and the first baffle 212 form the first stacking platform, thus the first stacking platform has the first receiving cavity. Four baffles 234 connected to the first baffle 212 are provided on both sides of the first receiving cavity along its width. Each baffle 234 is connected to a bent, inwardly extending baffle 235 that encloses a square cavity. The first stacking cavity 233 is formed between the baffles 234 and the baffles 235. The distance between two adjacent baffles 235 along the transverse direction (i.e., along the width) of the first conveying section 22 is less than the distance between the trays 1. The distance between two adjacent baffles 234 along the transverse direction of the first conveying section 22 is slightly greater than the width of the trays 1. The distance between two baffles 234 parallel to the conveying direction of the first conveying section 22 is less than the length of the trays 1. The distance between two baffles 235 parallel to the conveying direction of the first conveying section 22 is slightly greater than (i.e., the difference is 1-2 cm) the length of the trays 1. The bottom of each baffle 235 is suspended and the distance between it and the top of the first transmission toothed belt 2252 is slightly greater than the thickness of the material tray 1, so that the first stacking cavity 233 has a first moving cavity section that allows the first conveying part 22 to drive the material tray 1 to move, and a first stacking cavity section that stacks the material tray 1 vertically and blocks the material tray 1 horizontally. The first moving cavity section is formed by the bottom of the first transmission toothed belt 2252 and the baffle 234. After the material tray 1 is transferred from the first moving cavity section of the first discharge part 23a to the loading position 222 under the conveying of the first transmission toothed belt 2252, the first transmission toothed belt 2252 stops. After the first transfer part 24 transfers the product 14 in the material tray 1, the first transmission toothed belt 2252 continues to run and drives the empty material tray 1 into the first moving cavity section of the first receiving part 23b.

[0027] A first lifting space is formed inside the first receiving cavity by the two first transmission arms 2241. The first lifting part 231 is installed in the lifting space and includes a second driving member 2311 and a first lifting plate 2312. The second driving member 2311 is a linear motor, cylinder, etc. whose output shaft can extend and retract vertically. The first lifting plate 2312 is smaller than the lifting space and is connected to the output shaft of the second driving member 2311. After the material tray 1 moves into the first feeding cavity section, the second driving member 2311 runs and drives the first lifting plate 2312 to move vertically and push the material tray 1 into the first stacking cavity section.

[0028] Both the first discharge section 23a and the first receiving section 23b have two first material support sections 232, symmetrically arranged on both sides of the first stacking cavity section along the direction spanning the first conveying section 22. Each first material support section 232 includes a third drive member 2321 connected to the first transmission arm 2241, a first connecting bar 2322 connected to the output shaft of the third drive member 2321, and a first support plate 2323 for extending and retracting towards the stacking cavity section to support the material tray 1. The two third drive members 2321 are devices such as cylinders with extendable output shafts, and the output shafts protrude outwards in the opposite direction along the direction spanning the first conveying section 22. The first connecting bar 2322 is located outside the first stacking cavity section to avoid affecting the transport of the material tray 1. The first support plate 2323 protrudes inwards along the direction spanning the first conveying section 22, and a space is created between the first support plate 2323 and the top surface of the first conveying section 22 for the material tray 1 to move, allowing the material tray 1 to move relative to the inside of the first material support section 232. The third driving component 2321 causes the two first pallets 2323 to either move outwards and be in an open state or move inwards and be in a lifting state. When the two first pallets 2323 are in the open state, both first pallets 2323 are located outside the first material storage cavity. When the two first pallets 2323 are in the lifting state, both first pallets 2323 are located inside the first material storage cavity. The width of the first lifting plate 2312 is less than the distance between the two first pallets 2323 when they are in the lifting state.

[0029] The first transfer unit 24 includes a first support 241 disposed on a first base plate 211 and spanning the first conveying unit 22, a first lateral movement part 242 disposed on the first support 241 and spanning the first conveying unit 22 and the conveying mechanism 3, a first lifting part 243 connected to the first lateral movement part 242, a rotating part 244 connected to the output end of the first lifting part 243, and a first suction part 245 connected to the rotating part 244 for absorbing the product 14. The first lateral movement part 242 is used to drive the first lifting part 243 to span the first conveying unit 22 and the conveying mechanism 3, so that the first suction part 245 moves back and forth between the loading position 222 and the conveying mechanism 3. The first lifting part 243 is used to drive the first suction part 245 to move up and down to move closer to or away from the loading position 222 or the conveying mechanism 3. In another embodiment, the first transfer unit 24 can be directly replaced by a robot, and is not limited to this embodiment.

[0030] The first support 241 includes two vertically fixed frames fixed to the first base plate 211 and respectively disposed on both sides of the width of the first conveying section 22, and a first horizontal frame fixedly connected to the two first vertical frames. The first horizontal frame is arranged along the direction spanning the first conveying section 22 and the conveying mechanism 3 (i.e., the width direction of the first base plate 211). In order to protect the first transfer section 24 and the loading position 222, a first cover 25 is provided on the first base plate 211 and located around the first support 241. The bottom of the first cover 25 has a first opening to avoid the first conveying section 22.

[0031] The first transverse section 242 includes a fourth drive member mounted on top of the first bracket 241. The fourth drive member spans over the first conveying section 22 and the conveying mechanism 3 and can be a linear module, an electric linear guide 2434, or an electric slide. Therefore, the fourth drive member has a movable slider. The specific structure is prior art and will not be described in detail here.

[0032] The first lifting section 243 includes a first connecting bracket 2431 mounted on the first transverse section 242 and a fifth driving member 2432 mounted on the first connecting bracket 2431. Specifically, the first connecting bracket 2431 is connected to the movable slider of the fourth driving member so that the operation of the first transverse section 242 drives the entire first lifting section 243 to move laterally across the first conveying section 22 and the conveying mechanism 3. The first connecting bracket 2431 is connected to the movable slider and its bottom extends vertically downward from the side of the first transverse section 242 and is spaced between the first transverse section 242 and the first bracket 241. The fifth driving member 2432 is a linear cylinder or electric actuator with a telescopic output shaft. A first connecting plate 2433 is fixedly connected to the cylinder body of the fifth driving member 2432. The first connecting plate 2433 can be connected to the first connecting bracket 2431. A linear guide rail 2434 is vertically arranged on the first connecting plate 2433, and a slide rod 2435 is slidably arranged vertically inside the linear guide rail 2434.

[0033] The rotating part 244 is connected to the bottom end of the slide rod 2435 and can be a motor or a rotary cylinder. The output shaft of the rotating part 244 is rotatable and arranged downwards. The first suction part 245 is connected to the output shaft of the rotating part 244 so that it can rotate horizontally. The first suction part 245 includes a suction nozzle that communicates with an external suction source. The suction nozzle can be configured as four in a rectangular array.

[0034] It should be noted that the operation of each driving component, which drives other components, is controlled by sensors to measure the degree of movement, such as the distance traveled and the position reached.

[0035] Initially, relative to the first discharge section 23a, the first support plate 2323 of the first material support section 232 extends inward to enter the first material stacking cavity, and the first support plate 2323 supports the stacked material trays 1 from the bottom bottom material tray 1; relative to the first receiving section 23b, the first support plate 2323 of the first material support section 232 retracts outward to exit the first material stacking cavity. During use, on the first discharge section 23a, the first lifting section 231 drives the first lifting plate 2312 to move upward to support the stack of material trays 1, after which the first support section 232 retracts outward to the outside of the first material stacking cavity. Then, the first lifting section 231 drives the first lifting plate 2312 and the stack of material trays 1 to move downward by a distance equal to the thickness of one material tray 1, after which the first support section 232 extends inward until it supports the stack of material trays 1 located above the bottom material tray 1. Then, the first lifting plate 2312 continues to move downward until the bottom material tray 1 is supported by the first feed section. After the first conveying unit 221 is reached, the first conveying unit 22 moves the material tray 1 to the loading position 222. The first suction unit 245 of the first transfer unit 24 picks up the product 14 from the material tray 1 at the loading position 222 and rotates it at a suitable angle. Then, the first transfer unit 24 moves the product 14 to the conveying mechanism 3 and then returns to await the next transfer of the product 14. After the material tray 1 moves to the loading position 222, the first discharge unit 23a repeats the operation to transfer the next bottom material tray 1 located at the bottom to the first feeding end 221. After all products 14 are removed and the empty tray 1 is formed, the first conveying unit 22 conveys the empty tray 1 to the first discharge end 223, while the next tray 1 containing products 14 is transferred to the loading position 222. While the first discharge unit 23a is preparing the next tray 1, relative to the first receiving unit 23b, the first lifting unit 231 drives the first lifting plate 2312 to move upward and lift the empty tray 1 into the first stacking cavity until the bottom of the empty tray 1 is level with the bottom of the first support plate 2323. When the first support unit 232 extends inward, the first support plate 2322 extends inward. 2323 holds the empty material tray 1 and holds it in place. The first lifting plate 2312 retracts downward. When the next empty material tray 1 arrives, the first lifting plate 2312 lifts the empty material tray 1 upward so that it overlaps with the empty material tray 1 on the first support plate 2323 and stops. The first material support part 232 retracts outward and exits the first stacking cavity section. Then, the first lifting plate 2312 continues to lift the empty material tray 1 upward until the bottom of the empty material tray 1 on the first lifting plate 2312 is flush with the first support plate 2323. At this point, the first support plate 2323 extends inward to hold the stack of empty material trays 1 from the bottom. In this way, the lowering of the material tray 1 carrying product 14, the automatic separation of product 14 and material tray 1, and the recycling and stacking of empty material trays 1 can be completed, achieving full automation, improving efficiency and reducing manual labor. Moreover, the first receiving and dispatching part 23 of this embodiment can realize the single material distribution and lowering of the stack of material trays 1, and can also realize the recycling and stacking of a single empty material tray 1, realizing dual functions.

[0036] Please see Figures 10 to 14The conveying mechanism 3 includes a second cabinet 31, a first conveying frame 32 mounted on the top of the second cabinet 31, a flipping part 33 disposed on the first conveying frame 32, a guide part 34 disposed on the first conveying frame 32, and a waste gas recovery part 35 disposed on the first conveying frame 32. In another embodiment, the conveying structure may only include the first conveying frame 32 and a robotic arm for flipping the product 14, and is not limited to this embodiment.

[0037] The second cabinet 31 is identical to the first cabinet 21 and has various electrical equipment, power supply and heat dissipation equipment to provide electrical support for the first conveyor 32 and the flipping part 33. A horizontally arranged second base plate 311 is set on the top surface of the second cabinet 31. A second cover 36 is installed on the second base plate 311. The second cover 36 covers the first conveyor 32, the guide part 34 and the exhaust gas recovery part 35 inside its inner side, ensuring processing safety while effectively reducing the occurrence of various adverse situations in the processing process, such as exhaust gas pollution or mechanical safety hazards. The second cover 36 has a door that can be opened and a window for the first transfer part 24 and the unloading mechanism 5 to enter and exit. The second cover 36 can also be equipped with corresponding control panels and display screens, as well as corresponding alarm devices. When NG product 14 (i.e. non-conforming product 14) appears, an alarm is triggered and all mechanisms are stopped.

[0038] In this embodiment, three first conveyor frames 32 are arranged sequentially on the second base plate 311 along a direction parallel to the conveying direction of the first conveying section 22. Each first conveyor frame 32 includes at least two second transmission arms 321 extending parallel to the conveying direction of the first conveying section 22, and a second transmission section 322 disposed on the second transmission arms 321. The two second transmission arms 321 are spaced apart and parallel along the width (or transverse direction) of the first conveying section 22 and are both fixedly connected to the second base plate 311. Each second transmission section 322 includes two second transmission wheels, a second transmission toothed belt 3221 wound around the two second transmission wheels, and a sixth driving member for driving the second transmission wheels to rotate. Each second transmission unit 322 has two second transmission wheels spaced apart along the direction of the first conveying unit 22, with their axial directions parallel to the transverse direction of the first conveying unit 22. The second transmission toothed belt 3221 rotates in a direction parallel to the conveying direction of the first conveying unit 22 after the two second transmission wheels rotate, so that the conveying direction of the conveying mechanism 3 is consistent with the conveying direction of the first conveying unit 22 (hereinafter referred to as the "conveying direction"). The width (or transverse direction) dimension of the second transmission toothed belt 3221 is larger than the size of the product 14, so that the second transmission toothed belt 3221 can support the product 14 and drive the product 14 to move along the conveying direction. The sixth driving component is a drive device such as a rotary motor whose output shaft can rotate, and can be installed on the second cabinet 31 or on any of the second transmission arms 321. A rotating shaft extends coaxially from one end of each of the second transmission wheels. Gears 61 are fitted onto each rotating shaft and the output shaft of the sixth drive member. At least one gear 61 on the rotating shaft is connected to a gear 61 on the sixth drive member via a transmission belt 62. All gears 61 on the rotating shafts can be connected via transmission belts 62; all gears 61 on the rotating shafts can also be connected to gears 61 on the sixth drive member. Correspondingly, the number of gears 61 on the sixth drive member should correspond to the number of gears 61 on the rotating shafts, so that each of the second transmission belts 3221 can operate synchronously. In another embodiment, the sixth drive member can be configured as three, corresponding to the number of first conveyor frames 32, to drive the second transmission parts 322 on the three first conveyor frames 32 respectively. It should be noted that the conveying surface is configured as at least one as needed. In one embodiment, two conveying surfaces are configured, three second transmission arms 321 are configured, and two second transmission parts 322 are correspondingly configured and disposed between each pair of adjacent second transmission arms 321 to form two conveying surfaces. The number of positioning blocks 333 is consistent with the number of conveying surfaces.

[0039] In this embodiment, the top surface of the second transmission toothed belt 3221 on each of the first conveyor frames 32 is collectively defined as a conveying surface, which conveys the product 14 horizontally along the conveying direction. One side of one of the first conveyor frames 32 is located directly below the first transverse section 242, defining the position on the conveying surface directly below the first transverse section 242 as the feeding position 371, and the position on the other side of the conveying surface as the first laser engraving position 372. After the first transfer section 24 transfers the product 14 to the feeding position 371, the first conveyor frame 32 causes the conveying surface to move the product 14 from the feeding position 371 to the first laser engraving position 372 and then into the next first conveyor frame 32. Adjacent first conveyor frames 32 are spaced apart with a spacing less than half the distance between the products 14, so that the product 14 can enter the next first conveyor frame 32.

[0040] In this embodiment, the first conveyor frame 32 adjacent to the feed position 371 and the first laser engraving position 372 includes two secondary conveyor frames 32a. The two secondary conveyor frames 32a are arranged adjacent to each other along the conveying direction and are spaced apart. The top surface of the two secondary conveyor frames 32a is part of the conveying surface, so that a mounting cavity 331 is formed between the two secondary conveyor frames 32a that is recessed relative to the conveying surface. The flipping part 33 is disposed in the mounting cavity 331. The top surface of the secondary conveyor frame 32a close to the first laser engraving position 372 is defined as the front position 3731, and the top surface of the other secondary conveyor frame 32a that is far away from the first laser engraving position 372 relative to the front position 3731 is defined as the back position 3732. After the product 14 enters the front position 3731 from the first laser engraving position 372 on the conveying surface, the flipping part 33 drives the product 14 to flip onto the back position 3732 to complete the flipping of the product 14. Among them, the front position 3731 and the back position 3732 are jointly defined as the flip position 373.

[0041] The top of the second drive belt 3221 of the remaining first conveyor 32, adjacent to the secondary conveyor 32a and away from the feed position 371, is sequentially defined along the conveying direction as a second laser engraving position 374 and a discharge position 375. The second laser engraving position 374 is located on the side of the first conveyor 32 closer to the reverse position 3732 so that the product 14 that has been flipped can be transferred there for laser engraving. The discharge position 375 is located on the other side of the first conveyor 32 away from the reverse position 3732 so that the product 14 that has been laser engraved on the second laser engraving position 374 can be transferred to the discharge position 375.

[0042] The flipping part 33 is disposed on the flipping position 373 and includes the mounting cavity 331 formed between the two conveying secondary frames 32a, a rotating shaft 332 spanning the conveying surface and rotatably connected within the mounting cavity 331, a positioning block 333 connected to the rotating shaft 332, and a first driving member for driving the rotating shaft 332 to rotate axially. The axial direction of the rotating shaft 332 is arranged along the transverse direction and is located at the midpoint of the mounting cavity 331, so that the rotating shaft 332 is symmetrically distributed on both sides of the mounting cavity 331 along the conveying direction. The positioning block 333 is fixedly connected to the rotating shaft 332 radially, and the dimensions of the mounting cavities 331 on both sides of the rotating shaft 332 along the conveying direction are slightly larger than the dimensions of the positioning block 333, so that the positioning block 333 can rotate into the mounting cavities 331 on both sides of the rotating shaft 332.

[0043] Both ends of the rotating shaft 332 are rotatably connected to the two second transmission arms 321 of the first conveyor frame 32 via bearings. Specifically, the bearings are fixed to the second transmission arms 321, and the rotating shaft 332 is fixedly connected to the inner ring of the bearings for rotatable connection. One end of the rotating shaft 332 is fitted with a gear 61 and serves as a seventh drive unit for a rotary motor on the second cabinet 31. Similar to the sixth drive unit, a gear 61 can also be fitted on the output shaft of the seventh drive unit. A transmission belt 62 is wound around the gear 61 on both the seventh drive unit and the rotating shaft 332 to drive the rotating shaft 332. The output shaft of the seventh drive unit is configured to rotate 180 degrees and rotate in both directions, allowing the rotating shaft 332 to rotate 180 degrees in both directions. Each of the mounting cavities 331 on both sides of the rotating shaft 332 is equipped with a transverse limiting strip 3311 spanning the conveyor surface. The limiting strip 3311 is U-shaped and recessed relative to the conveyor surface. The two limiting strips 3311 are set at the same height and respectively support the positioning blocks 333. When the positioning block 333 rotates to be supported on any of the limiting bars 3311, the positioning block 333 is in a horizontal state. When the positioning block 333 rotates to the limiting bar 3311 near the front position 3731, the position of the positioning block 333 at this time is set as the initial position 334. When the positioning block 333 rotates to the limiting bar 3311 near the reverse position 3732, the position of the positioning block 333 at this time is set as the completed position 335. In this way, the positioning block 333 can be rotated 180 degrees from the initial position 334 to the completed position 335 along the conveying direction, so that the limiting bar 3311 completes the limiting of the positioning block 333.

[0044] The positioning block 333 has a positioning cavity 336 that is flush with the conveying surface when the positioning block 333 is in the initial position 334 or the completed position 335, allowing a portion of the product 14 to be inserted into it while the other portion of the product 14 remains on the conveying surface. The positioning cavity 336 extends radially away from the rotation axis 332 through the positioning block 333. When the positioning block 333 rotates to the initial position 334 or the completed position 335, the positioning cavity 336 is substantially flush with the conveying surface, allowing the product 14 to be input into the positioning cavity 336 from the front position 3731 or output from the positioning cavity 336 to the reverse position 3732. This completes the flipping of the product 14, allowing the product 14, after laser engraving on the front, to be flipped to the reverse side for laser engraving on the reverse side. In this way, even if the surface of product 14 is uneven or hollowed out, making it inconvenient to flip it by suction, it can still be flipped. Even if the surface of product 14 is affected by debris due to laser engraving, it can still be flipped, so that the flipping of product 14 is not affected by product 14 itself or processing steps.

[0045] Two guide sections 34 are provided on the feeding position 371, the front position 3731 located between the first laser engraving position 372 and the flipping part 33, the back position 3732 located between the second laser engraving position 374 and the flipping part 33, the first laser engraving position 372, and the discharge position 375, all facing the positioning cavity 336 along the conveying direction. This allows the product 14 transferred by the first transfer part 24 to the feeding position 371 to move to the first laser engraving position 372 according to a predetermined position. This ensures that the laser engraving mechanism 4 performs laser engraving on the front of the product 14, while also preparing the product 14, after processing on the first laser engraving position 372, to enter the front position 3731 to align with the positioning cavity 336 in the initial position 334. Furthermore, it allows the product 14 in the positioning cavity 336 to be positioned correctly. After the product 14 is completed and flipped at the finished position 335, it accurately enters the reverse position 3732. Then, the guide part 34 accurately moves the flipped product 14 to the second laser engraving position 374 for secondary laser engraving, completing the laser engraving operation on the reverse side of the product 14. The guide part 34 located at the discharge position 375 is used to ensure that the product 14 after the secondary laser engraving is accurately entered into the discharge position 375, so as to ensure that the unloading mechanism 5 can accurately transfer the laser-engraved product 14, so that the product 14 can accurately perform feeding, front and back laser engraving, flipping and unloading on a conveyor surface, providing accurate support and positioning for the laser engraving operation of the product 14, ensuring the laser engraving operation, and to a certain extent ensuring the accuracy and yield of the laser engraving operation.

[0046] In another embodiment, when there are two conveying surfaces, guide portions 34 facing one side of the conveying surface are provided on the second transmission arms 321 on both sides of the transverse direction at corresponding positions (i.e., feed position 371, front position 3731, etc.), so that each corresponding position has two guide portions 34, and the two opposing guide portions 34 are arranged at intervals to form a guide space between the two guide portions 34 for the product 14 to move on the conveying surface along the conveying direction of the conveying mechanism 3. The width of the guide space corresponds to and is adapted to the width of the product 14, and is slightly larger than the width of the product 14. For example, if the difference between the width of the guide space and the width of the product 14 is within half the width of the product 14, the smaller the difference, the higher the accuracy of guiding the product 14. Therefore, it is sufficient to have a small gap between the product 14 and the guide space.

[0047] The guide section 34 includes a connecting rod 341 connected to the second transmission arm 321 and extending towards the conveying surface, a guide rod 342 connected to the connecting rod 341 and with an adjustable angle, and an end rod 343 connected to the end of the guide rod 342 away from the discharge position 375 and with an adjustable angle. The connecting rod 341 is L-shaped and one end is screwed onto the second transmission arm 321. The screwing method allows the angle of the connecting rod 341 relative to the second transmission arm 321 to be adjustable, so as to adjust the guide space. Correspondingly, a plurality of first threaded holes are provided on the second transmission arm 321 along the conveying direction to facilitate adjustment of the connection position of the connecting rod 341. An L-shaped pad can be provided, with through holes corresponding to each of the first threaded holes on the pad. The pad is located between the connecting rod 341 and the second transmission arm 321. The other end of the connecting rod 341 extends towards the center of the conveying surface in the transverse direction and is screwed to the midpoint of the guide rod 342 by a screw or bolt. A second threaded hole is vertically formed at the end of the connecting rod 341 and the midpoint of the guide rod 342 to allow adjustment of the angle between the guide rod 342 and the connecting rod 341. In this embodiment, the guide rods 342 are distributed along the conveying direction. The end of the guide rod 342 facing the feed position 371 is screwed to the end of the end rod 343 by a screw or bolt. A third threaded hole is formed at the ends of both the guide rod 342 and the end rod 343 to allow adjustment of the angle between the end rod 343 and the guide rod 342. The end rod 343 also extends along the conveying direction, and the guiding space is formed between the two guide rods 342 and the end rod 343 at each position. To facilitate the rapid guidance and alignment of product 14, the end rod 343 is gradually narrowed towards the side away from the discharge position 375, so that the guide space away from the discharge position 375 is wide-mouthed. This ensures that the length of product 14 remains in the conveying direction when it moves on the conveying surface. In particular, when product 14 cooperates with the flipping part 33, it ensures that product 14 can accurately cooperate with the positioning cavity 336 to complete the flipping, while improving the positional accuracy of product 14 during laser engraving.

[0048] Two exhaust gas recovery units 35 are configured and respectively located on the first laser engraving position 372 and the second laser engraving position 374. The exhaust gas recovery units 35 are activated when the laser engraving mechanism 4 performs laser engraving processing on the product 14 on the first laser engraving position 372 and the second laser engraving position 374 to extract the fumes generated during the laser engraving operation. The exhaust gas recovery units 35 include two hollow recovery shells 351 that are open towards each other in the transverse direction. The inner cavities of the two recovery shells 351 are wide-mouthed and are respectively located on the two outermost second transmission arms 321 in the transverse direction, so that an exhaust gas recovery space is formed between the two recovery shells 351 facing the first laser engraving position 372 or the second laser engraving position 374. The two recovery shells 351 are connected to an external suction pump for extracting exhaust gas, and the outlet end of the suction pump is connected to a sealed cavity or a filter device.

[0049] Please see Figure 15 The laser engraving mechanism 4 includes a first laser engraving part 4b4a and a second laser engraving part, both connected to the second base plate 311. The first laser engraving part 4b4a is located to the side of the first laser engraving position 372 along the transverse direction, and the second laser engraving part is located to the side of the second laser engraving position 374 along the transverse direction. Both the first laser engraving part 4b4a and the second laser engraving part include a second bracket 41 connected to the second base plate 311, a second connecting plate 42 slidably mounted on the second bracket 41, and a laser engraving head 43 mounted on the second connecting plate 42. Guide rails 411, both arranged vertically, are provided on the second bracket 41. Two sliders slidably connected to the two guide rails 411 are connected to the second connecting plate 42, allowing the second connecting plate 42 to slide vertically relative to the second bracket 41. The second bracket 41 is provided with an adjustment part 44 for adjusting the height of the second connecting plate 42. The adjustment part 44 can be an electric slide arranged vertically, or it can be a rotating rod rotatably connected to the second bracket 41 vertically. The two ends of the rotating rod can be rotatably connected by bearings connected to the second bracket 41. A screw hole is opened on the connecting plate, and the rotating rod is screwed into the thread after forming a thread on the outer wall. The vertical movement of the connecting plate is realized by rotation, thereby realizing the lifting and lowering of the connecting plate and adjusting the height position of the laser engraving head 43.

[0050] It should be noted that a detection camera is installed on the laser engraving head 43. The laser engraving structure of the product 14 is photographed and compared with the laser engraving process by computer to determine whether the laser engraving is completed. If the laser engraving effect of the product 14 is unqualified, an alarm will be triggered so that the staff can take out the NG product 14. The OK product 14 (i.e. qualified product 14) will proceed to the next process.

[0051] Please see Figures 16 to 18The unloading mechanism 5 includes a third cabinet 51, a second conveying section 52 mounted on the third cabinet 51, two second receiving and dispatching sections 53 thereon for stacking trays 1 and transferring single empty trays 1 relative to the second conveying section 52, and a second transfer section 54 for transferring products 14 from the discharge position 375 to the empty tray 1. The second conveying section 52 has a second feeding end 521, a receiving position 522, and a second discharging end 523 in sequence. The receiving position 522 is located between the second feeding end 521 and the second discharging end 523. The second conveying section 52 can move the empty tray 1 from the second feeding end 521 to the receiving position 522 and then continue to move it to the second discharging end 523. One of the second receiving / dispatching units 53 is located near the second feeding end 521 to output a single empty tray 1 to the second feeding end 521, and the other second receiving / dispatching unit 53 is located near the second discharging end 523 to input a tray 1 containing product 14 from the second discharging end 523.

[0052] The structures of the third cabinet 51, the second conveying section 52, the second receiving and dispatching section 53, and the second transfer section 54 are completely identical to those of the first cabinet 21, the first conveying section 22, the first receiving and dispatching section 23, and the second transfer section 54 of the feeding mechanism 2. Each of the two second receiving and dispatching sections 53 includes a second stacking platform with a second stacking cavity on its inner side, a second lifting section 531 mounted on the second stacking platform to support the lowest empty material tray 1, and second supporting sections 532 located on both sides of the second stacking cavity to support the tray 1. The second feeding end 521 and the second discharging end 523 are located within the two second stacking cavities, respectively. That is, the structure of the second stacking platform is identical to that of the first stacking platform, but the top has a second baffle identical to the first baffle 212; the second lifting section 531 has the same structure as the first lifting section 231; and the second supporting section 532 has the same structure as the first supporting section 232. Therefore, the second conveying section 52 has a second feeding end 521 that is consistent with the first feeding end 221 and a second discharging end 523 that is consistent with the first discharging end 223. The second feeding end 521 and the second discharging end 523 extend into the two second receiving and dispatching sections 53 respectively. The second receiving and dispatching section 53 with the second feeding end 521 extending into it is defined as the second discharging section 53a, and the second receiving and dispatching section 53 with the second discharging end 523 extending into it is defined as the second receiving section 53b.

[0053] In use, the second discharge section 53a is used to stack the empty material trays 1 stacked in the first receiving section 23b. The transfer of the empty material trays 1 stack can be done manually or mechanically. The working principle of the second discharge section 53a is the same as that of the first discharge section 23a, but it is used to output the bottommost material tray 1. The difference between the second discharge section 53a and the first discharge section 23a is that the output is an empty material tray 1. Then, the second conveying section 52 transfers the empty material tray 1 to the receiving position 522 located between the second feeding end 521 and the second discharge end 523. A second suction section of the second transfer section 54, which has the same structure as the first suction section 245, is used to suck up the laser-engraved product 14 from the discharge position 375 in the transverse direction and transfer the product 14 to the empty material tray 1 on the receiving position 522 until all the accommodating cavities in the empty material tray 1 are filled with the laser-engraved qualified product 14. Finally, the second receiving unit 53b, using the same working principle as the first receiving unit 23b, recycles and stacks the material trays 1 to form a stack of material trays 1, thus completing the fully automated device, recycling, and stacking of product 14 and material trays 1. The specific structure of the unloading mechanism 5 is detailed in the loading mechanism 2 and will not be described in detail here.

[0054] The working method of one embodiment of the fully automatic laser engraving equipment of the present invention is as follows: After the stack of material trays 1 containing products 14 is placed on the first discharge section 23a, each device operates. The first lifting section 231 and the first material support section 232 cooperate to transfer the bottom material tray 1 to the first feeding end 221. After the first conveying section 22 transfers the material tray 1 to the loading position 222, the first transfer section 24 sequentially transfers the products 14 in the loading tray 1 of the loading position 222 to the feeding position 371. After all the products 14 in the loading tray 1 of the loading position 222 are taken out, the first conveying section 22 transfers the empty material tray 1 to the second receiving section 53b for stacking. The products 14 on the conveying mechanism 3 move from the feeding position 371 to the first laser engraving position 372 under the guidance of the guide section 34. The detection camera confirms the front and back of the products 14. For products 14 that are not front-facing, the operation stops and an alarm is triggered. For products that are front-facing... After the conveying mechanism 3 pauses, the first laser engraving unit 4b4a performs laser engraving on the front of product 14 until the laser engraving is completed. Then, the inspection camera continues to inspect the laser-engraved product 14. At this time, the positioning block 333 is in the initial position 334. After confirming that the laser engraving is OK, product 14 is transferred to the front position 3731 by the conveying surface and then aligned with the positioning cavity 336 by the guide part 34. As the conveying surface continues to move, product 14 enters the positioning cavity 336. Then, the flipping part 33 flips 180 degrees to the completion position 335. The conveying surface of the reverse position 3732 contacts product 14 and drives product 14 to move. After being guided by the guide part 34, it moves to the second laser engraving position 374. The inspection camera inspects product 14 and confirms that product 14 has been flipped to the reverse side. Then, the second laser engraving unit performs laser engraving on the reverse side of product 14 until the processing is completed. Then, the inspection camera inspects the laser-engraved product 14 until the laser engraving is confirmed to be OK. Afterwards, product 14 continues to be transferred from the conveyor surface to the discharge position 375 and then pauses. The second transfer unit 54 transfers the OK product 14 on the discharge position 375 to the empty material tray 1 on the discharge position 375 until the accommodating cavity in the empty material tray 1 is completely filled with OK products 14. Then, the second conveyor unit 52 transfers the material tray 1 to the second receiving unit 53b for stacking.

[0055] Compared with the prior art, the fully automatic laser engraving equipment of the present invention realizes the material tray 1, tray division and stacking through each receiving and dispatching unit, and realizes the movement of product 14 and the fully automatic separation and loading of product 14 from material tray 1 in cooperation with the corresponding conveying unit and each transfer unit, thereby improving the loading and sorting efficiency; the setting of the conveying mechanism 3 enables product 14 to complete guidance, front laser engraving, flipping and back laser engraving in one stop, and the flipping work of product 14 is simplified in cooperation with the guide and flipping unit 33.
