The cleaning transfer assembly 11 is in transmission connection with the cleaning assembly 12 and can drive the cleaning assembly 12 to move back and forth between the cleaning feeding station 300 and the cleaning discharging station 400. The cleaning assembly 12 can carry the workpiece 200 and clean the surface of the workpiece 200 in contact with the cleaning assembly 12 during the movement of the workpiece 200 from the cleaning feeding station 300 to the cleaning discharging station 400.

[0046] The cleaning feeding station 300 and the cleaning discharging station 400 are arranged at intervals along the first direction X, so that Figure 1 The first direction X is the left-right direction.

[0047] The cleaning assembly 12 can be one or more. If there are multiple cleaning assemblies 12, the cleaning transfer assembly 11 is in driving connection with all the cleaning assemblies 12 and can drive all the cleaning assemblies 12 to move synchronously to realize the simultaneous cleaning and transfer of multiple workpieces 200 and improve the cleaning and transfer efficiency.

[0048] The cleaning transfer assembly 11 drives the cleaning assembly 12 to reciprocate along the first direction X between the cleaning feeding station 300 and the cleaning discharging station 400. When the cleaning assembly 12 is at the cleaning feeding station 300, the cleaning assembly 12 is fed, the cleaning assembly 12 holds the workpiece 200, and the cleaning assembly 12 moves to the cleaning discharging station 400 under the action of the cleaning transfer assembly 11, and the cleaning of the workpiece 200 is completed in the process. After that, the cleaned workpiece 200 is transferred to the laser etching area for laser coding, and at the same time, the cleaning assembly 12 is emptied, and the cleaning assembly 12 returns to the cleaning feeding station 300 under the action of the cleaning transfer assembly 11 to be fed again.

[0049] By arranging the cleaning assembly 12 and the cleaning transfer assembly 11, the workpiece 200 is cleaned by the cleaning assembly 12 during the movement to the cleaning station, so that the position transfer of the workpiece 200 coincides with the cleaning time, and the work efficiency is improved.

[0050] In some embodiments, the cleaning transfer assembly 11 includes a cleaning transfer base 111, a cleaning driving member 112, a cleaning transfer shaft, a cleaning first transmission wheel, a cleaning second transmission wheel, a cleaning transmission belt, a cleaning driving wheel, a cleaning driven wheel, and a cleaning synchronous belt.

[0052] In other embodiments, the cleaning transfer assembly 11 can also include a cleaning driving member 112, a cleaning slide rail, and a cleaning slide block. The cleaning assembly 12 is mounted on the cleaning slide block, the cleaning driving member 112 drives the cleaning slide block to drive the cleaning assembly 12 to slide on the cleaning slide rail to realize the transfer of the cleaning assembly 12.

[0053] Of course, the structure of the cleaning transfer assembly 11 is not limited to the above two structures, and can be other structures, as long as the cleaning assembly 12 can be driven to reciprocate in the first direction X.

[0054] In some embodiments, the cleaning assembly 12 includes a cleaning vacuum carrier 121 and a liquid suction member, the liquid suction member is adsorbed on the cleaning vacuum carrier 121, and the liquid suction member can carry the workpiece 200 and clean the to-be-cleaned liquid on the surface of the workpiece 200 in contact with the liquid suction member.

[0055] As an example, the liquid suction member can be made of cloth, sponge or other materials with liquid suction capacity.

[0056] Under the action of the cleaning vacuum carrier 121, the liquid suction member is adsorbed on the cleaning vacuum carrier 121, and the workpiece 200 is adsorbed on the liquid suction member, so that the liquid suction member can carry the workpiece 200 and clean the to-be-cleaned liquid on the surface of the workpiece 200 in contact with the liquid suction member. This way of fixing and cleaning the workpiece 200 is simple and easy to operate, and has good cleaning effect.

[0057] In some embodiments, the cleaning vacuum carrier 121 includes a base 1211, an adsorption table 1212, and a pressing plate 1213, the adsorption table 1212 protrudes from the base 1211, the liquid suction member includes a liquid suction part and a mounting part, the liquid suction part is adsorbed on the adsorption table 1212, the mounting part is arranged around the circumference of the liquid suction part, and the mounting part is bent relative to the liquid suction part to the base 1211, and the pressing plate 1213 is sleeved outside the adsorption table 1212 and presses the mounting part. The way that the pressing plate 1213 is sleeved outside the adsorption table 1212 and presses the mounting part makes the liquid suction member reliable in installation, and facilitates disassembly and replacement of the liquid suction member.

[0058] The liquid suction part is adapted to the to-be-cleaned area on the workpiece 200, so that the liquid suction part can adsorb the developing liquid of the to-be-cleaned area of the workpiece 200 at one time when the liquid suction part contacts the to-be-cleaned area of the workpiece 200, and the liquid suction member has low loss and low cost.

[0059] As an example, the adsorption table 1212 can be a vacuum adsorption table 1212.

[0060] In some embodiments, the cleaning vacuum carrier 121 further includes a magnetic suction member, the base 1211 is provided with a plurality of mounting holes 12111 arranged along the circumference of the adsorption table 1212 at intervals, the magnetic suction member corresponds to the mounting holes 12111 one by one, and the magnetic suction member is installed in the corresponding mounting hole 12111. The pressing plate 1213 presses the mounting part by the magnetic attraction force of the magnetic suction member. By using the magnetic suction member, the installation and disassembly of the pressing plate 1213 can be realized, so as to facilitate the replacement of the liquid suction member, ensure the cleaning effect, and improve the replacement efficiency.

[0061] Of course, the pressing plate 1213 can but not limited to utilize the magnetic attraction force of the magnetic attraction member to press the mounting portion, and it can also realize the pressing of the mounting portion by means of screws, pins and other detachable members, which are not limited here.

[0062] In some embodiments, the cleaning vacuum carrier 121 further comprises a carrier base plate 1214, the base 1211 is mounted on the carrier base plate 1214, and the base 1211 and the carrier base plate 1214 define a vacuum suction cavity. The cleaning vacuum carrier 121 is provided with a vacuum suction hole 12121, which penetrates the suction base 1212 and the base 1211 and communicates with the vacuum suction cavity. The cleaning vacuum carrier 121 further comprises a vacuum pump 1215, which communicates with the vacuum suction cavity and can extract the gas in the vacuum suction cavity to form a negative pressure environment.

[0063] In some embodiments, the cleaning device 10 further comprises a cleaning base 13 and a mounting sliding block 14, and all the carrier base plates 1214 of the cleaning assemblies 12 are mounted on the cleaning base 13. The cleaning base 13 is connected with the cleaning synchronous belt through the mounting sliding block 14, so that the plurality of cleaning assemblies 12 can be linked and moved synchronously under the action of the same cleaning and transferring assembly 11, saving the setting of the cleaning and transferring assembly 11, simplifying the structure, reducing the cost, and improving the work efficiency.

[0064] Please refer to Figure 1 and refer to Figure 8 In some embodiments, the laser engraving device 100 further comprises a turnover device 30, which can hold the cleaned workpiece 200 and drive the workpiece 200 to overturn, so that the surface of the workpiece 200 that needs to be engraved faces upward, and the turnover device can hold the overturned workpiece 200 and move it to the laser engraving area.

[0065] Specifically, the workpiece 200 has a cleaning surface and an engraving surface. Whether the turnover device 30 needs to be set depends on whether the cleaning surface and the engraving surface of the workpiece 200 are the same surface or two opposite surfaces. The cleaning surface of the workpiece 200 refers to the surface that is contaminated by the cleaning liquid (such as developing solution, ink, etc.) and needs to be cleaned. The engraving surface of the workpiece 200 refers to the surface on which the laser engraving device 60 performs the action.

[0066] Taking the workpiece 200 as a glass panel and the cleaning surface and the engraving surface of the glass panel as two opposite surfaces as an example, in this embodiment, the cleaning surface of the glass panel always faces downward and forms the lower surface of the glass panel, and the engraving surface of the glass panel always faces upward and forms the upper surface of the glass panel. During the work process, the workpiece 200 does not need to be overturned, therefore, the laser engraving device 100 can not be provided with the turnover device 30.

[0067] In the specific working process, the cleaning device 10 carries the glass panel and cleans the cleaning surface of the glass panel in contact with the cleaning device 10. After cleaning, the transfer device moves the cleaned glass panel to the laser engraving area, and the laser engraving device 60 can laser engrave the laser code surface of the workpiece 200 located in the laser engraving area.

[0068] Taking the workpiece 200 as the glass panel and the cleaning surface and the laser code surface of the glass panel as the same surface as an example, in this embodiment, when the cleaning device 10 is loaded, the cleaning surface of the glass panel faces downward and forms the lower surface of the glass panel, and the laser code surface of the glass panel faces upward and forms the upper surface of the glass panel. In the working process, the workpiece 200 needs to be flipped, so the laser engraving equipment 100 needs to be provided with a flipping device 30.

[0069] In this embodiment, the workpiece 200 can sequentially complete the cleaning of the cleaning surface and the laser code operation of the laser code surface without flipping, which simplifies the operation process and structure of the laser engraving equipment 100, improves the production line efficiency, and reduces the manufacturing cost.

[0070] In the specific working process, the cleaning device 10 carries the glass panel and cleans the cleaning surface of the glass panel in contact with the cleaning device 10. After cleaning, the transfer device moves the cleaned glass panel to the laser engraving area, and the laser engraving device 60 can laser engrave the laser code surface of the workpiece 200 located in the laser engraving area.

[0071] In this embodiment, the laser engraving equipment 100 can be applied to the working condition that the cleaning surface and the laser code surface are the same, and the application range is wider.

[0072] In some embodiments, the flipping device 30 includes a flipping driving assembly 31, a flipping lifting assembly 32, and a flipping adsorption assembly 33. The flipping lifting assembly 32 is installed on the flipping driving assembly 31, the flipping adsorption assembly 33 is installed 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 lift, and the flipping driving assembly 31 can drive the flipping lifting assembly 32 to drive the flipping adsorption assembly 33 to flip.

[0073] Taking the flipping of the workpiece 200 as an example, the flipping lifting assembly 32 drives the flipping adsorption assembly 33 to descend, and the flipping adsorption assembly 33 adsorbs the workpiece 200 of the cleaning unloading station 400. Then, the flipping lifting assembly 32 drives the flipping adsorption assembly 33 to ascend, and the flipping adsorption assembly 33 moves away from the cleaning device 10 in the third direction Z to avoid interference between the flipping adsorption assembly 33 and the cleaning device 10. Then, the flipping driving assembly 31 drives the flipping lifting assembly 32 to drive the flipping adsorption assembly 33 and the workpiece 200 to flip, so that the upper surface and the lower surface of the workpiece 200 are exchanged.

[0074] By setting the turnover driving assembly 31, the turnover lifting assembly 32 and the turnover suction assembly 33, the turnover device 30 can conveniently turn the workpiece 200.

[0075] In some embodiments, the turnover driving assembly 31 comprises a turnover mounting seat 311, a turnover driving member 312, a rack 313, a turnover wheel 314, a turnover shaft 315 and a turnover connecting plate 316. The turnover driving member 312 and the turnover shaft 315 are both mounted on the turnover mounting seat 311. The turnover driving member 312 is in transmission connection with the rack 313. The turnover wheel 314 is sleeved and fixed on the turnover shaft 315 and is in engagement with the rack 313. The turnover lifting assembly 32 is connected with the turnover shaft 315 through the turnover connecting plate 316.

[0076] When the turnover driving member 312 is started, the power of the turnover driving member 312 is transmitted to the turnover lifting assembly 32 in sequence through the rack 313, the turnover wheel 314, the turnover shaft 315 and the turnover connecting plate 316, so as to realize the turnover of the turnover lifting assembly 32, the turnover suction assembly 33 and the workpiece 200. This kind of turnover realization mode is stable and reliable, and has high adjustment precision.

[0077] In other embodiments, the turnover driving assembly 31 can also only comprise the turnover driving member 312 and the turnover shaft 315.

[0078] The turnover lifting assembly 32 can be a pneumatic cylinder, an electric cylinder, an electric telescopic rod, etc. and can be selected according to needs.

[0079] The turnover suction assembly 33 comprises a turnover base 331 and a turnover vacuum suction head group protruding from the top side of the turnover base 331. The turnover base 331 is in transmission connection with the turnover lifting assembly 32. The turnover vacuum suction head group can suck the workpiece 200. Specifically, the turnover vacuum suction head group comprises a plurality of turnover vacuum suction heads 332. The plurality of turnover vacuum suction heads 332 can suck a plurality of positions of the workpiece 200, thereby improving the reliability of suction.

[0080] The number of the turnover vacuum suction head group is the same as and one-to-one corresponds to the number of the cleaning assembly 12. The turnover vacuum suction head group can suck the workpiece 200 cleaned by the cleaning vacuum carrier 121 of the corresponding cleaning assembly 12.

[0081] Please refer to Figure 1 , Figures 9 to 11In some embodiments, the transfer device includes a first transfer device 20 and a second transfer device 40. The first transfer device 20 is capable of picking up the cleaned workpiece 200 and moving the workpiece 200 to the second transfer device 40. The second transfer device 40 includes a positioning assembly 41 and a transfer assembly 43. The positioning assembly 41 is installed on the transfer assembly 43. The positioning assembly 41 is capable of fixing and positioning the workpiece 200. The transfer assembly 43 is capable of moving the workpiece 200 to the photographing area and the laser engraving area in sequence.

[0082] Specifically, the laser engraving device 100 has a transfer loading station 500, a guide station 600, and a laser engraving station 700. The transfer loading station 500 and the cleaning unloading station 400 are arranged along a second direction Y intersecting the first direction X. The transfer loading station 500, the guide station 600, and the laser engraving station 700 are arranged along the first direction X. The photographing area of the guide device 50 is located at the guide station 600. The laser engraving area of the laser engraving device 60 is located at the laser engraving station 700.

[0083] In actual operation, in embodiments not including the turnover device 30, the first transfer device 20 picks up the workpiece 200 from the cleaning unloading station 400 and moves the workpiece 200 to the positioning assembly 41 of the second transfer device 40 located at the transfer loading station 500. After the positioning assembly 41 fixes and positions the workpiece 200, the transfer assembly 43 moves the positioning assembly 41 and the workpiece 200 to the photographing area for photographing and the laser engraving area for laser coding in sequence. In embodiments including the turnover device 30, the first transfer device 20 picks up the workpiece 200 after being turned over by the turnover device 30 and moves the workpiece 200 to the positioning assembly 41 of the second transfer device 40 located at the transfer loading station 500. After the positioning assembly 41 fixes and positions the workpiece 200, the transfer assembly 43 moves the positioning assembly 41 and the workpiece 200 to the photographing area for photographing and the laser engraving area for laser coding in sequence.

[0084] The arrangement of the first transfer device 20 can improve the flexibility of the spatial layout of the laser engraving device 100, avoid interference between the installation positions of the devices, and ensure the smooth operation of the laser engraving device 100. The second transfer device 40 can position and transfer the workpiece 200, improving the stability and reliability of the workpiece 200 transfer.

[0085] Please refer to Figure 1 and refer to Figure 7The first transfer device 20 comprises a first transfer assembly 21, a first lifting assembly 22 and a first adsorption assembly 23. The first lifting assembly 22 is installed on the first transfer assembly 21, and the first adsorption assembly 23 is installed on the first lifting assembly 22 and can adsorb the workpiece 200. The first lifting assembly 22 can drive the first adsorption assembly 23 to lift along a third direction Z intersecting the first direction X and the second direction Y. The first transfer assembly 21 can drive the first lifting assembly 22 to drive the first adsorption assembly 23 to reciprocate along the second direction Y.

[0086] In the state of the laser engraving equipment 100, the second direction Y is the up-down direction. In the state of the first transfer device 20, the third direction Z is the up-down direction. Figure 1 In the state of the laser engraving equipment 100, the second direction Y is the up-down direction. In the state of the first transfer device 20, the third direction Z is the up-down direction. Figure 7 In the state of the laser engraving equipment 100, the second direction Y is the up-down direction. In the state of the first transfer device 20, the third direction Z is the up-down direction.

[0087] When the workpiece 200 does not need to be flipped, the first lifting assembly 22 drives the first adsorption assembly 23 to descend, and the first adsorption assembly 23 adsorbs the workpiece 200 in the cleaning and unloading station 400. Then, the first lifting assembly 22 drives the first adsorption assembly 23 to ascend, and the first adsorption assembly 23 moves away from the cleaning device 10 in the third direction Z to avoid interference between the first adsorption assembly 23 and the cleaning device 10, and to ensure smooth transfer of the workpiece 200 to the transfer and loading station 500. The first transfer assembly 21 drives the first lifting assembly 22 to drive the first adsorption assembly 23 to reciprocate along the second direction Y, so that the first adsorption assembly 23 switches between the cleaning and unloading station 400 and the transfer and loading station 500. After the first adsorption assembly 23 adsorbs the cleaned workpiece 200, the first transfer assembly 21 drives the first lifting assembly 22 to drive the first adsorption assembly 23 to move along the second direction Y towards the transfer and loading station 500, so as to transfer the workpiece 200 to the positioning assembly 41 of the second transfer device 40. Then, the first transfer assembly 21 drives the first lifting assembly 22 to drive the first adsorption assembly 23 to move away from the transfer and loading station 500 along the second direction Y, so as to re-take the workpiece 200 in the cleaning and unloading station 400 and transfer it.

[0088] When the workpiece 200 needs to be flipped, the first lifting assembly 22 drives the first adsorption assembly 23 to descend, the first adsorption assembly 23 adsorbs the workpiece 200 on the flipping device 30, then the first lifting assembly 22 drives the first adsorption assembly 23 to ascend, the first adsorption assembly 23 moves away from the flipping device 30 in the third direction Z to avoid interference between the first adsorption assembly 23 and the flipping device 30, and ensure that the workpiece 200 is smoothly transported to the transfer loading station 500. The first transfer assembly 21 drives the first lifting assembly 22 to move the first adsorption assembly 23 reciprocally along the second direction Y, so that the first adsorption assembly 23 is switched between the flipping device 30 and the transfer loading station 500. After the first adsorption assembly 23 adsorbs the workpiece 200, the first transfer assembly 21 drives the first lifting assembly 22 to move the first adsorption assembly 23 along the second direction Y towards the transfer loading station 500, so as to transfer the workpiece 200 to the positioning assembly 41 of the second transfer device 40, and then the first transfer assembly 21 drives the first lifting assembly 22 to move the first adsorption assembly 23 along the second direction Y away from the transfer loading station 500, so as to re-take the workpiece 200 on the flipping device 30 and transfer it.

[0089] By setting the first transfer assembly 21, the first lifting assembly 22 and the first adsorption assembly 23, the first transfer device 20 can conveniently transfer and transfer the workpiece 200.

[0090] As an example, the first transfer assembly 21 includes a first transfer base 211, a first driving member 212, a first transfer shaft, a first gear, a second gear, a first transmission belt, a first driving wheel, a first driven wheel and a first synchronous belt. The first driving member 212, the first transfer shaft, the second gear and the first driven wheel are all mounted on the first transfer base 211, and the first driving member 212 is in transmission connection with the first gear, the second gear and the first driving wheel are all 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 wheel and the first driven wheel, and the first lifting assembly 22 is mounted and fixed on the first synchronous belt.

[0091] When the first driving member 212 is started, the power of the first driving member 212 is transmitted to the first lifting assembly 22 in sequence through the first gear, the first transmission belt, the second gear, the first transfer shaft, the first driving wheel and the first synchronous belt, so as to realize the reciprocating movement of the first lifting assembly 22 and the first adsorption assembly 23 along the second direction Y. This way of realizing the reciprocating movement of the first lifting assembly 22 and the first adsorption assembly 23 along the second direction Y is stable and reliable.

[0092] In some other embodiments, the first transfer assembly 21 can also include a first driving member 212, a first sliding rail and a first sliding block. The first lifting assembly 22 is installed on the first sliding block, and the first driving member 212 drives the first sliding block to drive the first lifting assembly 22 to slide on the first sliding rail, so as to realize the transfer of the first lifting assembly 22 and the first adsorption assembly 23.

[0093] The first lifting assembly 22 can be a pneumatic cylinder, an electric cylinder, an electric telescopic rod or the like, which can be selected as needed.

[0094] The first adsorption assembly 23 includes a first base and a first vacuum carrier 231. The first base is in transmission connection with the first lifting assembly 22, and the first lifting assembly 22 drives the first base to lift. The first vacuum carrier 231 is installed on the first base, and the first vacuum carrier 231 can adsorb the workpiece 200.

[0095] The number of the first vacuum carriers 231 is the same as that of the cleaning assemblies 12 and corresponds to the cleaning assemblies 12 one by one. The first vacuum carriers 231 can adsorb the workpieces 200 cleaned by the cleaning vacuum carriers 121 of the corresponding cleaning assemblies 12.

[0096] Of course, the structure of the first adsorption assembly 23 is not limited to the above, and can also be other structures, as long as it can adsorb the workpiece 200.

[0097] Please refer to Figure 1 and Figure 2 again, and refer to Figures 9 to 11 at the same time. The second transfer device 40 further includes a translation assembly 42. The positioning assembly 41 is installed on the translation assembly 42, and the positioning assembly 41 has at least two clamping positions 41123 capable of clamping the workpiece 200. The translation assembly 42 is installed on a transfer assembly 43, and the transfer assembly 43 can drive the translation assembly 42 to drive the positioning assembly 41 to pass through the photographing area and the laser engraving area in sequence. The translation assembly 42 can drive the positioning assembly 41 to drive the workpieces 200 in each clamping position 41123 to pass through the photographing area in sequence.

[0098] The clamping positions 41123 and the cleaning assemblies 12 are both multiple and correspond to each other one by one. The cleaning vacuum carrier 121 of the cleaning assembly 12 adsorbs the workpiece 200 and transfers it to the corresponding clamping position 41123 and fixes it. For example, Figure 2 and Figure 10 , the clamping positions 41123 and the cleaning assemblies 12 are both two.

[0099] Specifically, the transfer assembly 43 drives the translation assembly 42 to drive the positioning assembly 41 to reciprocate along the first direction X, so that the positioning assembly 41 can be moved from the transfer loading station 500 to the guide station 600, or from the guide station 600 to the laser engraving station 700. When the positioning assembly 41 is located at the transfer loading station 500, the first transfer device 20 moves the cleaned workpiece 200 from the cleaning device 10 or the turnover device 30 to the clamping position 41123, and then the transfer assembly 43 drives the translation assembly 42 to drive the positioning assembly 41 and the workpiece 200 to move along the first direction X and pass through the guide station 600 and the laser engraving station 700 in sequence. When the workpiece 200 passes through the guide station 600, the translation assembly 42 drives the positioning assembly 41 to drive the workpiece 200 to translate along the second direction Y, so that all clamping positions 41123 on the positioning assembly 41 can pass through the photographing area in sequence and be photographed, thereby obtaining the laser code position of the workpiece 200 on each clamping position 41123. Then, the transfer assembly 43 drives the translation assembly 42, the positioning assembly 41 and the workpiece 200 to move to the laser engraving device 60, and the laser engraving device 60 engraves the laser code at the laser code position of each workpiece 200. After the laser code is completed, the workpiece is unloaded. After unloading, the transfer assembly 43 drives the translation assembly 42 to drive the positioning assembly 41 to return to the transfer loading station 500 to wait for loading.

[0100] As an example, the laser engraving device 60 can have a plurality of laser heads, all of which correspond to all clamping positions 41123 one by one, and the laser heads can engrave the laser code at the laser code position of the workpiece 200 on the corresponding clamping position 41123. As an example, the laser head of the laser engraving device 60 can also be only one, and after the laser head completes the laser code at one of the laser code positions, the translation assembly 42 drives the positioning assembly 41 to drive the workpiece 200 on each clamping position 41123 to translate along the second direction Y, so that the laser head can engrave the workpiece 200 on each clamping position 41123 in sequence.

[0101] In this embodiment, the positioning assembly 41 can position and fix the workpiece 200, reducing the risk of falling of the workpiece 200 during transfer. The design of the transfer assembly 43 can ensure that the workpiece 200 can smoothly pass through the guide station 600 and the laser engraving station 700 to achieve precise laser code. The design of the translation assembly 42 uses the same set of guide devices 50 to obtain the laser code position of each workpiece 200, reducing the use of the guide device 50, simplifying the structure of the laser engraving equipment 100, and reducing the manufacturing cost.

[0102] Please refer to Figure 9 and Figure 10In some embodiments, the positioning assembly 41 comprises a positioning module 411, a first clamping module 412 and / or a second clamping module 413. The positioning module 411 comprises a positioning base 4111 and at least two positioning units 4112, each of the positioning units 4112 comprises a first positioning member 41121 and a second positioning member 41122, the first positioning member 41121 and the second positioning member 41122 jointly define a clamping position 41123 capable of placing the workpiece 200, and the first positioning member 41121 and the second positioning member 41122 are capable of abutting against two adjacent sides of the workpiece 200 respectively. The first clamping module 412 comprises a first clamping driving member 4121 and at least two first clamping members 4122, each of the first clamping members 4122 is correspondingly arranged at one side of the first positioning member 41121 of the corresponding clamping position 41123, and under the action of the first clamping driving member 4121, each of the first clamping members 4122 is capable of moving close to or away from the corresponding first positioning member 41121. The second clamping module 413 comprises a second clamping driving member 4131 and at least two second clamping members 4132, each of the second clamping members 4132 is correspondingly arranged at one side of the second positioning member 41122 of the corresponding clamping position 41123, and under the action of the second clamping driving member 4131, each of the second clamping members 4132 is capable of moving close to or away from the corresponding second positioning member 41122.

[0103] In some embodiments, the first direction X is the direction in which each of the first clamping members 4122 moves close to or away from the corresponding first positioning member 41121, and the second direction Y is the direction in which each of the second clamping members 4132 moves close to or away from the corresponding second positioning member 41122.

[0104] The positioning assembly 41 comprises the positioning module 411, the first clamping module 412 and / or the second clamping module 413, which means that the positioning assembly 41 comprises the positioning module 411 and comprises the first clamping module 412 and / or the second clamping module 413. As an example, the positioning assembly 41 comprises the positioning module 411, the first clamping module 412 and the second clamping module 413, which can clamp the workpiece 200 in multiple directions and has better clamping reliability.

[0105] 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.

[0106] Specifically, the first clamping driving member 4121 and the second clamping driving member 4131 can be a pneumatic cylinder, an electric cylinder, an electric support rod, etc.

[0107] When the workpieces 200 are not moved to the positioning assembly 41, each first clamping piece 4122 moves away from the corresponding first positioning piece 41121 in the first direction X, and meanwhile, each second clamping piece 4132 moves away from the corresponding second positioning piece 41122 in the second direction Y, so that the clamping position 41123 has a larger space, facilitating the subsequent placement of the workpieces 200 in the clamping position 41123. When each workpiece 200 is moved to the corresponding clamping position 41123 and abuts against the first positioning piece 41121 and the second positioning piece 41122 on the corresponding clamping position 41123, each first clamping piece 4122 moves close to the corresponding first positioning piece 41121 in the first direction X, and each second clamping piece 4132 moves close to the corresponding second positioning piece 41122 in the second direction Y, so as to clamp and fix each workpiece 200. Then, under the action of the transfer assembly 43, each workpiece 200 sequentially passes through the guide station 600 and the laser engraving station 700, and is engraved with a laser code in the laser engraving station 700. After the laser coding is completed, each first clamping piece 4122 moves away from the corresponding first positioning piece 41121 in the first direction X again, and meanwhile, each second clamping piece 4132 moves away from the corresponding second positioning piece 41122 in the second direction Y, so as to release each workpiece 200, facilitating the subsequent unloading.

[0108] In the above-mentioned positioning assembly 41, all the first clamping pieces 4122 are driven to move by the same first clamping driving piece 4121, and all the second clamping pieces 4132 are driven to move by the same second clamping driving piece 4131. Compared with the traditional design that each first clamping piece 4122 is driven to move by a corresponding first shaft group and each second clamping piece 4132 is driven to move by a corresponding second shaft group, the use amount of the first shaft group and the second shaft group is greatly saved, the overall layout is simplified, the structure is simpler, the manufacturing cost is reduced, the occupied space is reduced, and the maintainability is improved.

[0109] In some embodiments, the first clamping module 412 includes a first clamping base 4123, the first clamping driving piece 4121 is in transmission connection with the first clamping base 4123, and all the first clamping pieces 4122 are installed on the same side of the first clamping base 4123; the first clamping driving piece 4121 drives the first clamping base 4123 to drive each first clamping piece 4122 to move close to or away from the corresponding first positioning piece 41121. In this case, a shorter transmission distance can be provided between the first clamping driving piece 4121 and all the first clamping pieces 4122, and the transmission efficiency is high and stable.

[0110] In some embodiments, the positioning module 411 comprises two positioning units 4112, and the second positioning member 41122 of one positioning unit 4112 is located close to one side of the other positioning unit 4112. The second clamping module 413 comprises two second clamping members 4132, and the two second clamping members 4132 are located on the two sides of the two positioning units 4112 away from each other; when the two second clamping members 4132 move towards each other, the two second clamping members 4132 synchronously approach the respective opposite second positioning members 41122, and when the two second clamping members 4132 move away from each other, the two second clamping members 4132 synchronously move away from the respective opposite second positioning members 41122. In this way, when the two second clamping members 4132 move along the second direction Y, they are hardly interfered by other elements, have a larger degree of freedom range, and can adapt to the clamping needs of workpieces 200 of different sizes without occupying a large space.

[0111] Of course, the arrangement of the two second clamping members 4132 of the second clamping module 413 is not limited to the above two kinds, for example, in some other embodiments, the two second clamping members 4132 of the second clamping module 413 can be located on the two sides of the two positioning units 4112 close to each other.

[0112] In some embodiments, the positioning module 411 further comprises a positioning vacuum carrier, and the positioning vacuum carrier corresponds to the clamping position 41123 in one-to-one correspondence. The positioning vacuum carrier is installed on the corresponding clamping position 41123 and can adsorb the workpiece 200.

[0113] Specifically, the positioning vacuum carrier is located on the bottom side of the workpiece 200 and adsorbs the workpiece 200. In this way, when the workpiece 200 is fixed on the clamping position 41123, the first positioning member 41121 and the first clamping member 4122 cooperate and limit the degree of freedom of the workpiece 200 in the first direction X, the second positioning member 41122 and the second clamping member 4132 cooperate and limit the degree of freedom of the workpiece 200 in the second direction Y, and the positioning vacuum carrier limits the degree of freedom of the workpiece 200 in the third direction Z, thereby improving the firmness of the workpiece 200.

[0114] In some embodiments, the translation assembly 42 comprises a translation mounting seat, a translation driving member 422, a translation screw rod 423, and a translation nut 424. The translation mounting seat is installed on the transfer assembly 43. The translation driving member 422 is installed on the translation mounting seat and is in transmission connection with the translation screw rod 423. The translation nut 424 is sleeved on the translation screw rod 423. The positioning assembly 41 is installed on the translation nut 424. The translation driving member 422 drives the translation screw rod 423 to drive the translation nut 424 and the positioning assembly 41 to translate.

[0115] The translation of the workpiece 200 in all clamping positions 41123 on the positioning assembly 41 can be realized by using a set of translation assemblies 42. Compared with the conventional translation of different clamping positions 41123 by using different translation shaft sets, the use amount of translation shaft sets is greatly saved, the structure of the translation assembly 42 is simpler, and the manufacturing cost is reduced.

[0116] For the convenience of description and labeling, the transfer assembly 43 is named as a second transfer assembly, and the specific structure of the second transfer assembly is described.

[0117] The second transfer assembly includes a second transfer base, a second driving member, a second transfer shaft, a third gear, a fourth gear, a second transmission belt, a second driving wheel, a second driven wheel, and a second synchronous belt.

[0118] The transfer driving member, the transfer transfer shaft, the transfer second transmission wheel, and the transfer driven wheel are all installed on the transfer base, and the transfer driving member is in transmission connection with the transfer first transmission wheel. The second driving member, the second transfer shaft, the fourth gear, and the second driven wheel are all installed on the second transfer base, and the second driving member is in transmission connection with the third gear. The fourth gear and the second driving wheel are both sleeved and fixed on the second transfer shaft. The second transmission belt is sleeved on the third gear and the fourth gear. The second synchronous belt is sleeved on the second driving wheel and the second driven wheel. The translation assembly 42 is installed and fixed on the second synchronous belt.

[0119] The second driving member is started, and the power of the second driving member is transmitted to the translation assembly 42 in sequence through the third gear, the second transmission belt, the fourth gear, the second transfer shaft, the second driving wheel, and the second synchronous belt, so as to realize the reciprocating movement of the translation assembly 42 and the positioning assembly 41 in the first direction X. This kind of way of realizing the reciprocating movement of the translation assembly 42 and the positioning assembly 41 in the first direction X is stable and reliable.

[0120] In other embodiments, the second transfer assembly can also include a second driving member, a second sliding rail, and a second sliding block. The translation assembly 42 is installed on the second sliding block, the second driving member drives the second sliding block to slide on the second sliding rail to realize the transfer of the translation assembly 42 and the positioning assembly 41.

[0121] Of course, the structure of the second transfer assembly is not limited to the above two kinds, and can also be other structures, as long as it can drive the translation assembly 42 and the positioning assembly 41 to reciprocate in the first direction X.

[0122] Please refer to Figure 11In some embodiments, the guiding device 50 comprises 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 with 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 assembly 41 under the action of the adjusting rod 52. Wherein, the adjusting plate 53 adjusts the position of the camera 54 relative to the positioning assembly 41 in the third direction Z under the action of the adjusting rod 52.

[0123] As an example, the adjusting rod 52 can be a screw rod and arranged along the third direction Z, the adjusting rod 52 can fine-tune the position of the adjusting plate 53 and the camera 54 in the third direction Z by tightening or loosening with the mounting plate 51.

[0124] Of course, the adjusting mode of the position of the adjusting plate 53 is not limited to the above, but also can be other modes, such as the adjusting rod 52 is selectively mounted on one of the plurality of positions of the mounting plate 51 arranged along the third direction Z, so as to realize the position of the adjusting plate 53 is adjustable.

[0125] The position of the adjusting plate 53 and the camera 54 relative to the mounting plate 51 in the third direction Z is adjustable, so that the focal length of the camera 54 can be adjusted, and the image captured by the camera 54 is clearer, so as to accurately obtain the position of the barcode on the workpiece 200.

[0126] The above laser engraving equipment 100 comprises a cleaning device 10, a transfer device and a laser engraving device 60.

Moreover, the cleaning device 10 can clean the surface of the workpiece 200 in contact with the cleaning device 10 after carrying the workpiece 200, and the workpiece 200 does not need to be flipped before cleaning, so the structure and process are simple, the work efficiency is high, and the production line production demand can be met. In addition, since the cleaning device 10 in the present application can directly clean the surface of the workpiece 200 in contact with the cleaning device 10, this cleaning method will not crush the workpiece 200 during cleaning, and the cleaning reliability is good and the qualified rate is high.
