[0052] Please see Figure 1 and Figure 2 This application provides a laser engraving device 100, which can clean and laser-engrave the workpiece 200 after stress testing. The workpiece 200 can be a glass panel or other types of material, depending on actual needs. For ease of explanation, the following embodiments use a glass panel as an example for the workpiece 200.

[0053] The laser engraving equipment 100 includes a cleaning device 10, a transfer device, and a laser engraving device 60. The cleaning device 10 carries the workpiece 200 and cleans the surface of the workpiece 200 that contacts the cleaning device 10. The guiding device 50 has a photographing area, and the laser engraving device 60 has a laser engraving area. The transfer device moves the cleaned workpiece 200 to the laser engraving area, where the laser engraving device 60 can laser engrave on the surface of the workpiece 200. By setting up the cleaning device 10, transfer device, and laser engraving device 60, the laser engraving device 60 can automatically perform cleaning, transfer, and laser engraving operations on the workpiece 200, facilitating automated laser engraving. Furthermore, after cleaning the workpiece 200, the cleaning device 10 can clean the surface of the workpiece 200 that contacts the cleaning device 10 without needing to flip the workpiece 200 before cleaning. The structure and process are simple, the work efficiency is high, and it can meet the production line requirements. Furthermore, since the cleaning device 10 in this application can directly clean the surface of the workpiece 200 that comes into contact with the cleaning device 10, this cleaning method will not damage the workpiece 200 during the cleaning process, and the cleaning reliability is good and the pass rate is high.

[0054] In some embodiments, the laser engraving device 100 further includes a guide device 50, which has a photographing area. The transfer device can drive the workpiece 200 to pass through the photographing area and the laser engraving area in sequence. The guide device 50 can take a picture of the workpiece 200 located in the photographing area and obtain the laser code position on the surface of the workpiece 200. The laser engraving device 60 can engrave laser code at the laser code position of the workpiece 200 located in the laser engraving area according to the information obtained by the guide device 50, so as to improve the accuracy of the laser code.

[0055] Please refer to it again. Figure 1 And see also Figures 2 to 6In some embodiments, the laser engraving equipment 100 has a cleaning loading station 300 and a cleaning unloading station 400. The cleaning device 10 includes a cleaning transfer component 11 and at least one cleaning component 12. The cleaning transfer component 11 is connected to the cleaning component 12 and can drive the cleaning component 12 to reciprocate between the cleaning loading station 300 and the cleaning unloading station 400. The cleaning component 12 can carry the workpiece 200 and clean the surface of the workpiece 200 in contact with the cleaning component 12 during the process of moving the workpiece 200 from the cleaning loading station 300 to the cleaning unloading station 400.

[0056] Cleaning loading station 300 and cleaning unloading station 400 are arranged at intervals along the first direction X, so as to Figure 1 Taking the state of the laser engraving equipment 100 as an example, the first direction X is the left and right direction.

[0057] The cleaning component 12 can be one or more. If there are multiple components, the cleaning transfer component 11 is connected to all the cleaning components 12 and can drive all the cleaning components 12 to move synchronously at the same time, so as to realize the simultaneous cleaning and transfer of multiple workpieces 200 and improve the cleaning and transfer efficiency.

[0058] The cleaning transfer assembly 11 drives the cleaning assembly 12 to reciprocate along the first direction X between the cleaning loading station 300 and the cleaning unloading station 400. When the cleaning assembly 12 is at the cleaning loading station 300, it loads and picks up the workpiece 200, and moves it to the cleaning unloading station 400 under the action of the cleaning transfer assembly 11, completing the cleaning of the workpiece 200 during this process. Afterwards, the transfer device transfers the cleaned workpiece 200 to the laser engraving area for laser marking. Simultaneously, the cleaning assembly 12 is freed up and returns to the cleaning loading station 300 for reloading under the action of the cleaning transfer assembly 11.

[0059] By setting up the cleaning component 12 and the cleaning transfer component 11, the workpiece 200 is cleaned by the cleaning component 12 during the process of moving to the cleaning station, so that the time of workpiece 200 position transfer and cleaning coincides, thereby improving work efficiency.

[0060] In some embodiments, the cleaning transfer assembly 11 includes a cleaning transfer base 111, a cleaning drive 112, a cleaning transfer shaft, a first cleaning drive wheel, a second cleaning drive wheel, a cleaning drive belt, a cleaning drive wheel, a cleaning driven wheel, and a cleaning timing belt. The cleaning drive 112, the cleaning transfer shaft, the second cleaning drive wheel, and the cleaning driven wheel are all mounted on the cleaning transfer base 111, and the cleaning drive 112 is drive-connected to the first cleaning drive wheel. The second cleaning drive wheel and the cleaning drive wheel are both sleeved and fixed on the cleaning transfer shaft. The cleaning drive belt is sleeved on the first cleaning drive wheel and the second cleaning drive wheel. The cleaning timing belt is sleeved on the cleaning drive wheel and the cleaning driven wheel. The cleaning assembly 12 is mounted and fixed on the cleaning timing belt.

[0061] When the cleaning drive unit 112 is started, the power of the cleaning drive unit 112 is transmitted to the cleaning assembly 12 in sequence through the first cleaning transmission wheel, the cleaning transmission belt, the second cleaning transmission wheel, the cleaning transfer shaft, the cleaning drive wheel and the cleaning timing belt, so as to realize the reciprocating motion of the cleaning assembly 12 in the first direction X, and this reciprocating motion is stable and reliable.

[0062] In some other embodiments, the cleaning transfer assembly 11 may also include a cleaning drive 112, a cleaning slide rail and a cleaning slider. The cleaning assembly 12 is mounted on the cleaning slider, and the cleaning drive 112 drives the cleaning slider to move the cleaning assembly 12 on the cleaning slide rail to achieve the transfer of the cleaning assembly 12.

[0063] Of course, the structure of the cleaning transfer component 11 is not limited to the two mentioned above, and can also be other structures, as long as it can drive the cleaning component 12 to reciprocate in the first direction X.

[0064] In some embodiments, the cleaning component 12 includes a cleaning vacuum carrier 121 and a liquid suction member. The liquid suction member is adsorbed onto the cleaning vacuum carrier 121 and is capable of carrying the workpiece 200 and cleaning the surface of the workpiece 200 in contact with the liquid suction member to be cleaned.

[0065] As an example, the absorbent can be made of cloth, sponge, or other materials with absorbent properties.

[0066] Under the action of the cleaning vacuum carrier 121, the liquid suction component is adsorbed onto the cleaning vacuum carrier 121, and the workpiece 200 is adsorbed onto the liquid suction component, so that the liquid suction component can carry the workpiece 200 and clean the liquid to be cleaned on the surface of the workpiece 200 in contact with the liquid suction component. This method of fixing and cleaning the workpiece 200 is simple and easy to operate, and has a good cleaning effect.

[0067] In some embodiments, the cleaning vacuum carrier 121 includes a base 1211, an adsorption stage 1212, and a pressure plate 1213. The adsorption stage 1212 protrudes from the base 1211. The liquid suction component includes a liquid suction part and a mounting part. The liquid suction part is adsorbed onto the adsorption stage 1212. The mounting part is arranged circumferentially around the liquid suction part and is bent relative to the liquid suction part onto the base 1211. The pressure plate 1213 is sleeved on the adsorption stage 1212 and presses the mounting part firmly. The way the pressure plate 1213 is sleeved on the adsorption stage 1212 and presses the mounting part firmly ensures reliable installation of the liquid suction component and facilitates disassembly and replacement of the liquid suction component.

[0068] The liquid suction part is adapted to the area to be cleaned on the workpiece 200. Therefore, when the liquid suction part comes into contact with the area to be cleaned on the workpiece 200, it can absorb the developer solution of the area to be cleaned on the workpiece 200 in one go. The liquid suction part has low wear and tear and low cost.

[0069] As an example, the adsorption stage 1212 can be an adsorption stage 1212 capable of vacuum adsorption.

[0070] In some embodiments, the cleaning vacuum carrier 121 further includes magnetic suction components. A plurality of mounting holes 12111 are spaced circumferentially along the adsorption stage 1212 on the base 1211. Each magnetic suction component corresponds to one of the mounting holes 12111, and the magnetic suction component is installed within the corresponding mounting hole 12111. The pressure plate 1213 uses the magnetic force of the magnetic suction components to press the mounting portion firmly. The magnetic suction components enable the installation and removal of the pressure plate 1213, facilitating the replacement of the liquid suction components, ensuring cleaning effectiveness, and improving replacement efficiency.

[0071] Of course, the pressure plate 1213 can, but is not limited to, use the magnetic attraction of the magnetic component to press the mounting part, and it can also use detachable components such as screws and pins to press the mounting part. The specifics are not limited here.

[0072] In some embodiments, the cleaning vacuum carrier 121 further includes a carrier base plate 1214, a base 1211 mounted on the carrier base plate 1214, and the base 1211 defining a vacuum adsorption chamber. The cleaning vacuum carrier 121 has a vacuum adsorption hole 12121, which passes through the adsorption stage 1212 and the base 1211, and communicates with the vacuum adsorption chamber. The cleaning vacuum carrier 121 also includes a vacuum extraction pipe 1215, which communicates with the vacuum adsorption chamber and is capable of extracting gas from the vacuum adsorption chamber to create a negative pressure environment.

[0073] In some embodiments, the cleaning device 10 further includes a cleaning base 13 and a mounting slider 14. The carrier base plate 1214 of all cleaning components 12 is mounted on the cleaning base 13, and the cleaning base 13 is connected to the cleaning timing belt through the mounting slider 14, so that multiple cleaning components 12 can move in conjunction and move synchronously under the action of the same cleaning transfer component 11, saving the setting of the cleaning transfer component 11, which not only simplifies the structure and reduces costs, but also improves work efficiency.

[0074] Please refer to it again. Figure 1 And see also Figure 8 In some embodiments, the laser engraving equipment 100 further includes a flipping device 30, which can pick up the cleaned workpiece 200 and flip the workpiece 200 so that the surface of the workpiece 200 that needs to be laser-engraved is facing up, and the transfer device can pick up the flipped workpiece 200 and move it to the laser engraving area.

[0075] Specifically, the workpiece 200 has a clean surface and a laser-coded surface. Whether a flipping device 30 is needed depends on whether the clean surface and the laser-coded surface of the workpiece 200 are the same surface or two surfaces that are opposite to each other. The clean surface of the workpiece 200 refers to the surface that is contaminated with cleaning fluid (such as developer, ink, etc.) and needs to be cleaned, while the laser-coded surface of the workpiece 200 refers to the surface on which the laser engraving device 60 performs its operation.

[0076] Taking the workpiece 200 as a glass panel, and the clean surface and the laser-coded surface of the glass panel as two surfaces that are arranged opposite to each other, in this embodiment, the clean surface of the glass panel always faces down and forms the lower surface of the glass panel, and the laser-coded surface of the glass panel always faces up and forms the upper surface of the glass panel. During the operation, the workpiece 200 does not need to be flipped. Therefore, the laser engraving equipment 100 does not need to be equipped with a flipping device 30.

[0077] The specific working process is as follows: the cleaning device 10 carries the glass panel and cleans the surface of the glass panel that contacts the cleaning device 10. After cleaning, the transfer device moves the cleaned glass panel to the laser engraving area, where the laser engraving device 60 can engrave on the laser-marked surface of the workpiece 200 located in the laser engraving area.

[0078] Taking workpiece 200 as a glass panel, and the clean surface and the laser-coded surface of the glass panel as the same surface, in this embodiment, when the cleaning device 10 feeds the workpiece, the clean surface of the glass panel faces down and forms the lower surface of the glass panel, and the laser-coded surface of the glass panel faces up and forms the upper surface of the glass panel. During the operation, workpiece 200 needs to be flipped, so the laser engraving equipment 100 needs to be equipped with a flipping device 30.

[0079] In this embodiment, the cleaning of the clean surface and the laser coding of the laser coding surface of the workpiece 200 can be completed sequentially without flipping, which simplifies the operation process and structure of the laser engraving equipment 100, improves production line efficiency, and reduces manufacturing costs.

[0080] The specific working process is as follows: The cleaning device 10 carries the glass panel and cleans the surface of the glass panel that contacts the cleaning device 10. After cleaning, the flipping device 30 picks up the cleaned workpiece 200 and flips it so that the laser-coded surface of the workpiece 200 faces upward. Then, the transfer device moves the cleaned glass panel to the laser engraving area, where the laser engraving device 60 can engrave laser codes on the laser-coded surface of the workpiece 200 located in the laser engraving area.

[0081] In this embodiment, the laser engraving device 100 can be used under the same working conditions as the clean surface and the laser-coded surface, thus having a wider range of applications.

[0082] In some embodiments, the flipping device 30 includes a flipping drive assembly 31, a flipping lifting assembly 32, and a flipping adsorption assembly 33. The flipping lifting assembly 32 is mounted on the flipping drive assembly 31, and the flipping adsorption assembly 33 is mounted on the flipping lifting assembly 32 and can adsorb the workpiece 200. The flipping lifting assembly 32 can drive the flipping adsorption assembly 33 to rise and fall, and the flipping drive assembly 31 can drive the flipping lifting assembly 32 to flip the flipping adsorption assembly 33.

[0083] Taking the workpiece 200 flipping as an example, the flipping lifting component 32 drives the flipping adsorption component 33 to descend, and the flipping adsorption component 33 adsorbs the workpiece 200 at the cleaning unloading station 400. Then, the flipping lifting component 32 drives the flipping adsorption component 33 to rise, and the flipping adsorption component 33 moves away from the cleaning device 10 in the third direction Z to avoid interference between the flipping adsorption component 33 and the cleaning device 10. Then, the flipping drive component 31 drives the flipping lifting component 32 to flip the flipping adsorption component 33 and the workpiece 200, so that the upper and lower surfaces of the workpiece 200 are interchanged.

[0084] By setting up the flipping drive component 31, the flipping lifting component 32 and the flipping adsorption component 33, the flipping device 30 can easily flip the workpiece 200.

[0085] In some embodiments, the flip drive assembly 31 includes a flip mounting base 311, a flip drive component 312, a rack 313, a flip wheel 314, a flip shaft 315, and a flip connecting plate 316. The flip drive component 312 and the flip shaft 315 are both mounted on the flip mounting base 311, and the flip drive component 312 is connected to the rack 313 in a transmission connection. The flip wheel 314 is sleeved and fixed on the flip shaft 315, and the flip wheel 314 meshes with the rack 313. The flip lifting assembly 32 is connected to the flip shaft 315 through the flip connecting plate 316.

[0086] When the flipping drive 312 is activated, its power is transmitted sequentially through the rack 313, flipping wheel 314, flipping shaft 315, and flipping connecting plate 316 to the flipping lifting assembly 32, thereby achieving the flipping of the flipping lifting assembly 32, the flipping adsorption assembly 33, and the workpiece 200. This method of achieving flipping is stable, reliable, and has high adjustment accuracy.

[0087] In some other embodiments, the flip drive assembly 31 may also include only the flip drive 312 and the flip shaft 315.

[0088] The tilting and lifting assembly 32 can be made of pneumatic cylinders, electric cylinders, electric telescopic rods, etc., and the specific type can be selected according to the needs.

[0089] The flip-adsorption assembly 33 includes a flip base 331 and a flip vacuum suction head assembly protruding from the top side of the flip base 331. The flip base 331 is tractively connected to the flip lifting assembly 32. The flip vacuum suction head assembly can adsorb the workpiece 200. Specifically, the flip vacuum suction head assembly includes multiple flip vacuum suction heads 332, which can adsorb multiple positions of the workpiece 200, improving the reliability of the adsorption.

[0090] The number of rotating vacuum head assemblies is the same as the number of cleaning components 12 and corresponds one-to-one. The rotating vacuum head assemblies can adsorb the workpiece 200 cleaned by the corresponding cleaning vacuum carrier 121 of the cleaning component 12.

[0091] Please see Figure 1 , Figures 9 to 11 In some embodiments, the transfer device includes a first transfer device 20 and a second transfer device 40. The first transfer device 20 can hold the cleaned workpiece 200 and move the workpiece 200 to the second transfer device 40. The second transfer device 40 includes a positioning component 41 and a transfer component 43. The positioning component 41 is mounted on the transfer component 43. The positioning component 41 can fix and position the workpiece 200. The transfer component 43 can move the workpiece 200 to the photography area and the laser engraving area in sequence.

[0092] Specifically, the laser engraving equipment 100 has a transfer loading station 500, a guiding station 600, and a laser engraving station 700. The transfer loading station 500 and the cleaning unloading station 400 are arranged at intervals along a second direction Y that intersects with the first direction X. The transfer loading station 500, the guiding station 600, and the laser engraving station 700 are arranged at intervals along the first direction X. The photo-taking area of ​​the guiding device 50 is located at the guiding station 600, and the laser engraving area of ​​the laser engraving device 60 is located at the laser engraving station 700.

[0093] In actual operation, in embodiments excluding the flipping device 30, the first transfer device 20 picks up the workpiece 200 from the cleaning unloading station 400 and moves it to the positioning component 41 of the second transfer device 40 located at the intermediate loading station 500. After the positioning component 41 fixes and positions the workpiece 200, the transfer component 43 moves the positioning component 41 and the workpiece 200 sequentially to the photography area for taking pictures and the laser engraving area for laser marking. In embodiments including the flipping device 30, the first transfer device 20 picks up the workpiece 200 flipped by the flipping device 30 and moves it to the positioning component 41 of the second transfer device 40 located at the intermediate loading station 500. After the positioning component 41 fixes and positions the workpiece 200, the transfer component 43 moves the positioning component 41 and the workpiece 200 sequentially to the photography area for taking pictures and the laser engraving area for laser marking.

[0094] The first transfer device 20 enhances the spatial layout flexibility of the laser engraving equipment 100, preventing interference between the installation positions of various devices and ensuring the smooth operation of the laser engraving equipment 100. The second transfer device 40 can position and transfer the workpiece 200, improving the stability and reliability of the workpiece 200 transfer.

[0095] Please refer to it again. Figure 1 And see also Figure 7 The first transfer device 20 includes a first transfer component 21, a first lifting component 22, and a first adsorption component 23. The first lifting component 22 is mounted on the first transfer component 21, and the first adsorption component 23 is mounted on the first lifting component 22 and can adsorb the workpiece 200. The first lifting component 22 can drive the first adsorption component 23 to move up and down along a third direction Z that intersects both the first direction X and the second direction Y. The first transfer component 21 can drive the first lifting component 22 to drive the first adsorption component 23 to reciprocate along the second direction Y.

[0096] by Figure 1 Taking the state of the laser engraving equipment 100 as an example, the second direction Y is the up and down direction. Figure 7 Taking the state of the first transfer device 20 as an example, the third direction Z is the up and down direction.

[0097] When workpiece 200 does not need to be flipped, the first lifting component 22 drives the first adsorption component 23 to descend, and the first adsorption component 23 adsorbs workpiece 200 from the cleaning unloading station 400. Then, the first lifting component 22 drives the first adsorption component 23 to rise, and the first adsorption component 23 moves away from the cleaning device 10 in the third direction Z to avoid interference between the first adsorption component 23 and the cleaning device 10, ensuring a smooth and unobstructed transfer of workpiece 200 to the intermediate loading station 500. The first transfer component 21 drives the first lifting component 22 to move the first adsorption component 23 reciprocally along the second direction Y, so that the first adsorption component 23 switches between the cleaning unloading station 400 and the intermediate loading station 500. After the first adsorption component 23 adsorbs the cleaned workpiece 200, the first transfer component 21 drives the first lifting component 22 to move the first adsorption component 23 along the second direction Y toward the transfer loading station 500 so as to transfer the workpiece 200 onto the positioning component 41 of the second transfer device 40. Then, the first transfer component 21 drives the first lifting component 22 to move the first adsorption component 23 away from the transfer loading station 500 along the second direction Y so as to pick up the workpiece 200 from the clean unloading station 400 again and transfer it.

[0098] When workpiece 200 needs to be flipped, the first lifting component 22 drives the first adsorption component 23 to descend, and the first adsorption component 23 adsorbs workpiece 200 on the flipping device 30. Then, the first lifting component 22 drives the first adsorption component 23 to rise, and the first adsorption component 23 moves away from the flipping device 30 in the third direction Z to avoid interference between the first adsorption component 23 and the flipping device 30, ensuring a smooth and unobstructed transfer of workpiece 200 to the intermediate loading station 500. The first transfer component 21 drives the first lifting component 22 to move the first adsorption component 23 reciprocally along the second direction Y, so that the first adsorption component 23 switches between the flipping device 30 and the intermediate loading station 500. After the first adsorption component 23 adsorbs the workpiece 200, the first transfer component 21 drives the first lifting component 22 to move the first adsorption component 23 along the second direction Y toward the transfer loading station 500 so as to transfer the workpiece 200 onto the positioning component 41 of the second transfer device 40. Then, the first transfer component 21 drives the first lifting component 22 to move the first adsorption component 23 away from the transfer loading station 500 along the second direction Y so as to pick up the workpiece 200 on the flipping device 30 again and transfer it.

[0099] By setting up the first transfer component 21, the first lifting component 22 and the first adsorption component 23, the first transfer device 20 can conveniently transfer and transport the workpiece 200.

[0100] As an example, the first transfer assembly 21 includes a first transfer base 211, a first drive member 212, a first transfer shaft, a first gear, a second gear, a first transmission belt, a first driving pulley, a first driven pulley, and a first synchronous belt. The first drive member 212, the first transfer shaft, the second gear, and the first driven pulley are all mounted on the first transfer base 211, and the first drive member 212 is connected to the first gear in a transmission manner. The second gear and the first driving pulley are both sleeved and fixed on the first transfer shaft. The first transmission belt is sleeved on the first gear and the second gear. The first synchronous belt is sleeved on the first driving pulley and the first driven pulley. The first lifting assembly 22 is mounted and fixed on the first synchronous belt.

[0101] The first driving component 212 is activated, and the power of the first driving component 212 is transmitted sequentially to the first lifting assembly 22 through the first gear, the first transmission belt, the second gear, the first transfer shaft, the first drive wheel, and the first synchronous belt, so as to realize the reciprocating motion of the first lifting assembly 22 and the first adsorption assembly 23 in the second direction Y. This method of realizing the reciprocating motion of the first lifting assembly 22 and the first adsorption assembly 23 in the second direction Y is stable and reliable.

[0102] In some other embodiments, the first transfer component 21 may also include a first drive member 212, a first slide rail and a first slider, with the first lifting component 22 mounted on the first slider. The first drive member 212 drives the first slider to move the first lifting component 22 on the first slide rail to achieve the transfer of the first lifting component 22 and the first adsorption component 23.

[0103] The first lifting component 22 can be a pneumatic cylinder, an electric cylinder, an electric telescopic rod, etc., and the specific type can be selected according to the needs.

[0104] The first adsorption component 23 includes a first base and a first vacuum carrier 231. The first base is connected to the first lifting component 22. The first lifting component 22 drives the first base to rise and fall. The first vacuum carrier 231 is installed on the first base and can adsorb the workpiece 200.

[0105] The number of first vacuum carriers 231 is the same as the number of cleaning components 12 and corresponds one-to-one. The first vacuum carriers 231 can adsorb the workpieces 200 cleaned by the corresponding cleaning vacuum carriers 121 of the cleaning components 12.

[0106] Of course, the structure of the first adsorption component 23 is not limited to the one mentioned above, and can also be other structures, as long as it can adsorb the workpiece 200.

[0107] Please refer to it again. Figure 1 and Figure 2 And see also Figures 9 to 11The second transfer device 40 also includes a translation component 42, a positioning component 41 mounted on the translation component 42, and the positioning component 41 has at least two clamping positions 41123 capable of clamping the workpiece 200. The translation component 42 is mounted on the transfer component 43, and the transfer component 43 can drive the translation component 42 to move the positioning component 41 through the photographing area and the laser engraving area in sequence. The translation component 42 can drive the positioning component 41 to move the workpiece 200 of each clamping position 41123 through the photographing area in sequence.

[0108] The clamping positions 41123 and the cleaning components 12 are multiple and correspond one-to-one. The workpiece 200 adsorbed by the cleaning vacuum carrier 121 of the cleaning component 12 is transferred to the corresponding clamping position 41123 and fixed. Figure 2 and Figure 10 For example, there are two clamping positions 41123 and two cleaning components 12.

[0109] Specifically, the transfer component 43 drives the translation component 42 to move the positioning component 41 back and forth along the first direction X, so that the positioning component 41 can move from the intermediate loading station 500 to the laser engraving station 700 via the guide station 600, or from the laser engraving station 700 to the intermediate loading station 500 via the guide station 600. When the positioning component 41 is located at the intermediate loading station 500, the first transfer device 20 picks up the cleaned workpiece 200 and moves it to the clamping position 41123 for positioning by the cleaning device 10 or the flipping device 30. Then, the transfer component 43 drives the translation component 42 to move the positioning component 41 and the workpiece 200 along the first direction X and pass through the guide station 600 and the laser engraving station 700 in sequence. When workpiece 200 passes through guide station 600, translation component 42 drives positioning component 41 to move workpiece 200 along the second direction Y, so that all clamping positions 41123 on positioning component 41 can sequentially pass through the imaging area and take pictures, thereby obtaining the laser marking position of workpiece 200 at each clamping position 41123. Then, transfer component 43 drives translation component 42, positioning component 41 and workpiece 200 to laser marking device 60. Laser marking device 60 laser marks the laser marking positions of each workpiece 200. After laser marking is completed, the workpiece is unloaded. After unloading, transfer component 43 drives translation component 42 to move positioning component 41 back to transfer loading station 500 to wait for loading.

[0110] As an example, the laser engraving device 60 can have multiple laser heads, each corresponding to one of the clamping positions 41123. Each laser head can engrave laser marks on the workpiece 200 at the corresponding clamping position 41123. Alternatively, the laser engraving device 60 can have only one laser head. After the laser head completes engraving at one of the clamping positions, the translation component 42 drives the positioning component 41 to move the workpiece 200 at each clamping position 41123 along the second direction Y, so that the laser head can sequentially engrave laser marks on the workpiece 200 at each clamping position 41123.

[0111] In this embodiment, the positioning component 41 can position and fix the workpiece 200, reducing the risk of the workpiece 200 falling during transportation. The design of the transfer component 43 ensures that the workpiece 200 can smoothly pass through the guide station 600 and the laser engraving station 700 to achieve accurate laser marking. The design of the translation component 42 allows the same set of guide devices 50 to obtain the laser marking position of each workpiece 200, reducing the use of guide devices 50, simplifying the structure of the laser engraving equipment 100, and thus reducing manufacturing costs.

[0112] Please see Figure 9 and Figure 10 In some embodiments, the positioning component 41 includes a positioning module 411, a first clamping module 412, and / or a second clamping module 413. The positioning module 411 includes a positioning base 4111 and at least two positioning units 4112. Each positioning unit 4112 includes a first positioning element 41121 and a second positioning element 41122. The first positioning element 41121 and the second positioning element 41122 together define a clamping position 41123 for placing the workpiece 200. The first positioning element 41121 and the second positioning element 41122 can respectively abut against the adjacent sides of the workpiece 200. The first clamping module 412 includes a first clamping drive member 4121 and at least two first clamping members 4122. Each first clamping member 4122 corresponds to a clamping position 41123 and is disposed opposite to a first positioning member 41121 on one side of its corresponding clamping position 41123. Under the action of the first clamping drive member 4121, each first clamping member 4122 moves closer to or further away from its corresponding first positioning member 41121. The second clamping module 413 includes a second clamping drive member 4131 and at least two second clamping members 4132. Each second clamping member 4132 corresponds to a clamping position 41123 and is disposed opposite to a second positioning member 41122 on one side of its corresponding clamping position 41123. Under the action of the second clamping drive member 4131, each second clamping member 4132 moves closer to or further away from its corresponding second positioning member 41122.

[0113] The direction in which each first clamping member 4122 approaches or moves away from its corresponding first positioning member 41121 is the first direction X, and the direction in which each second clamping member 4132 approaches or moves away from its corresponding second positioning member 41122 is the second direction Y.

[0114] The positioning component 41 includes a positioning module 411, a first clamping module 412, and / or a second clamping module 413. This means that the positioning component 41 includes a positioning module 411 and also includes a first clamping module 412 and / or a second clamping module 413. As an example, the positioning component 41 includes a positioning module 411, a first clamping module 412, and a second clamping module 413, which enables clamping of the workpiece 200 in multiple directions, resulting in superior clamping reliability.

[0115] In the first clamping module 412, the first positioning member 41121 positions the short side of the workpiece 200, and in the second clamping module 413, the second positioning member 41122 positions the long side of the workpiece 200.

[0116] Specifically, the first clamping drive member 4121 and the second clamping drive member 4131 can both be cylinders, electric cylinders, electric struts, etc.

[0117] When the workpiece 200 has not moved onto the positioning assembly 41, each first clamping member 4122 moves away from its corresponding first positioning member 41121 in the first direction X. At the same time, each second clamping member 4132 moves away from its corresponding second positioning member 41122 in the second direction Y, so that the clamping position 41123 has a larger space, which facilitates the subsequent placement of the workpiece 200 in the clamping position 41123. When each workpiece 200 moves to its corresponding clamping position 41123 and abuts against the first positioning member 41121 and the second positioning member 41122 on the corresponding clamping position 41123, each first clamping member 4122 moves closer to its corresponding first positioning member 41121 in the first direction X, and each second clamping member 4132 moves closer to its corresponding second positioning member 41122 in the second direction Y, so as to clamp and fix each workpiece 200. Then, under the action of the transfer component 43, each workpiece 200 passes through the guide station 600 and the laser engraving station 700 in sequence, and is laser-engraved at the laser engraving station 700. After the laser engraving is completed, each first clamping member 4122 moves away from its corresponding first positioning member 41121 in the first direction X. At the same time, each second clamping member 4132 moves away from its corresponding second positioning member 41122 in the second direction Y, so as to release each workpiece 200 and facilitate unloading.

[0118] In the aforementioned positioning component 41, all the first clamping members 4122 move under the drive of the same first clamping drive member 4121, and all the second clamping members 4132 move under the drive of the same second clamping drive member 4131. Compared with the traditional design where each first clamping member 4122 is designed with its own corresponding first axis group to drive the movement of each first clamping member 4122, and each second clamping member 4132 is designed with its own corresponding second axis group to drive the movement of each second clamping member 4132, this design greatly saves the amount of first axis groups and second axis groups used, simplifies the overall layout, makes the structure simpler, reduces manufacturing costs, reduces the footprint, and improves maintainability.

[0119] In some embodiments, the first clamping module 412 includes a first clamping base 4123, a first clamping drive 4121 is connected to the first clamping base 4123, and all first clamping members 4122 are mounted on the same side of the first clamping base 4123. The first clamping drive 4121 drives the first clamping base 4123 to move each first clamping member 4122 synchronously closer to or further away from its respective first positioning member 41121. In this case, a relatively short transmission distance can be set between the first clamping drive 4121 and all the first clamping members 4122, resulting in high transmission efficiency and stable transmission.

[0120] In some embodiments, the positioning module 411 includes two positioning units 4112, with the second positioning element 41122 of each positioning unit 4112 located on the side closer to the other positioning unit 4112. The second clamping module 413 includes two second clamping elements 4132, located on opposite sides of the two positioning units 4112. When the two second clamping elements 4132 move toward each other, they synchronously approach their respective opposing second positioning elements 41122; when the two second clamping elements 4132 move away from each other, they synchronously move away from their respective opposing second positioning elements 41122. Thus, when the two second clamping elements 4132 move along the second direction Y, they are almost unaffected by interference from other components, have a large degree of freedom to adapt to the clamping needs of workpieces 200 of different sizes, and do not occupy a large space.

[0121] Of course, the arrangement of the two second clamping members 4132 of the second clamping module 413 is not limited to the two above. For example, in some other embodiments, the two second clamping members 4132 of the second clamping module 413 may be located on both sides of the two positioning units 4112 that are close to each other.

[0122] In some embodiments, the positioning module 411 further includes a positioning vacuum carrier, which corresponds one-to-one with the clamping position 41123. The positioning vacuum carrier is installed on the corresponding clamping position 41123 and can adsorb the workpiece 200.

[0123] Specifically, the positioning vacuum carrier is located on the bottom side of the workpiece 200 and adsorbs the workpiece 200. Thus, when the workpiece 200 is fixed in the clamping position 41123, the first positioning member 41121 and the first clamping member 4122 cooperate to restrict the degree of freedom of the workpiece 200 in the first direction X, and the second positioning member 41122 and the second clamping member 4132 cooperate to restrict the degree of freedom of the workpiece 200 in the second direction Y. The positioning vacuum carrier restricts the degree of freedom of the workpiece 200 in the third direction Z, thereby improving the reliability of the workpiece 200 fixation.

[0124] In some embodiments, the translation component 42 includes a translation mounting base, a translation drive 422, a translation screw 423, and a translation nut 424. The translation mounting base is mounted on the transfer component 43. The translation drive 422 is mounted on the translation mounting base and is connected to the translation screw 423 for transmission. The translation nut 424 is sleeved on the translation screw 423. The positioning component 41 is mounted on the translation nut 424. The translation drive 422 drives the translation screw 423 to move the translation nut 424 and the positioning component 41.

[0125] By using a set of translation components 42, the workpiece 200 of all clamping positions 41123 on the positioning component 41 can be translated. Compared with the traditional method of using different translation axis groups to achieve translation of different clamping positions 41123, the amount of translation axis groups used is greatly reduced. The structure of the translation component 42 is simpler and the manufacturing cost is reduced.

[0126] For ease of explanation and labeling, the transfer component 43 will be named the second transfer component below, and the specific structure of the second transfer component will be described.

[0127] The second transfer assembly includes a second transfer base, a second drive member, a second transfer shaft, a third gear, a fourth gear, a second transmission belt, a second drive pulley, a second driven pulley, and a second synchronous belt.

[0128] The transfer drive component, transfer shaft, second transfer drive wheel, and transfer driven wheel are all mounted on the transfer base, and the transfer drive component is connected to the first transfer drive wheel. The second drive component, second transfer shaft, fourth gear, and second driven wheel are all mounted on the second transfer base, and the second drive component is connected to the third gear. The fourth gear and second drive wheel are both sleeved and fixed on the second transfer shaft. The second transmission belt is sleeved on the third and fourth gears, and the second synchronous belt is sleeved on the second drive wheel and second driven wheel. The translation component 42 is mounted and fixed on the second synchronous belt.

[0129] The second driving component is activated, and its power is transmitted sequentially through the third gear, the second transmission belt, the fourth gear, the second transfer shaft, the second drive wheel, and the second synchronous belt to the translation component 42, thereby realizing the reciprocating motion of the translation component 42 and the positioning component 41 in the first direction X. This method of realizing the reciprocating motion of the translation component 42 and the positioning component 41 in the first direction X is stable and reliable.

[0130] In some other embodiments, the second transfer component may also include a second drive member, a second slide rail and a second slider. The translation component 42 is mounted on the second slider. The second drive member drives the second slider to slide the second transfer component on the second slide rail to realize the transfer of the translation component 42 and the positioning component 41.

[0131] Of course, the structure of the second transfer component is not limited to the two mentioned above, and can also be other structures, as long as it can drive the translation component 42 and the positioning component 41 to reciprocate in the first direction X.

[0132] Please see Figure 11 In some embodiments, the guiding device 50 includes a mounting plate 51, an adjusting rod 52, an adjusting plate 53, and a camera 54. The adjusting rod 52 is mounted on the mounting plate 51 and connected to the adjusting plate 53. The camera 54 is mounted on the adjusting plate 53, and the adjusting plate 53 can adjust the position of the camera 54 relative to the positioning component 41 under the action of the adjusting rod 52. Specifically, the adjusting plate 53 adjusts the position of the camera 54 relative to the positioning component 41 in the third direction Z under the action of the adjusting rod 52.

[0133] As an example, the adjusting rod 52 can be a screw and set along the third direction Z. The adjusting rod 52 can be tightened or loosened with the mounting plate 51 to make fine adjustments to the position of the adjusting plate 53 and the camera 54 in the third direction Z.

[0134] Of course, the position adjustment method of the adjusting plate 53 is not limited to the one mentioned above. Other methods are also possible, such as selectively installing the adjusting rod 52 at one of the multiple positions set along the third direction Z of the mounting plate 51, thereby realizing the position adjustment of the adjusting plate 53.

[0135] The adjustment plate 53 and camera 54 are adjustable relative to the mounting plate 51 in the third direction Z. This allows the focal length of the camera 54 to be adjusted so that the image it captures is clearer, thus enabling precise acquisition of the laser mark position on the workpiece 200.

[0136] In the aforementioned positioning component 41, transfer device, and laser engraving equipment 100, all the first clamping members 4122 move under the drive of the same first clamping drive member 4121, and all the second clamping members 4132 move under the drive of the same second clamping drive member 4131. Compared with the traditional design where each first clamping member 4122 is designed with its own corresponding first axis group to drive the movement of each first clamping member 4122, and each second clamping member 4132 is designed with its own corresponding second axis group to drive the movement of each second clamping member 4132, this design greatly saves the amount of first axis groups and second axis groups used, simplifies the overall layout, makes the structure simpler, reduces manufacturing costs, reduces the footprint, and improves maintainability.

[0137] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0138] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
