Description

Technical Field

[0001] This invention relates to the field of circuit board assembly technology, and more particularly to a dispensing assembly device. Background Technology

[0002] Currently, in the production of electronic products such as mobile phones and laptops, flexible circuit boards need to be assembled onto electronic components. The assembly process of flexible circuit boards is generally as follows: first, adhesive is applied to the electronic components, then the flexible circuit board is pressed onto the electronic components, and finally the adhesive on the electronic components is cured, so that the electronic components and the flexible circuit board are firmly bonded together. However, since the dispensing, pressing and curing operations in the existing technology are carried out separately by different equipment, the production efficiency is low and the equipment occupies a large space.

[0003] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0062] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0063] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0066] Please see Figures 1 to 20 This embodiment provides a dispensing assembly device, which includes a conveying device 1, a dispensing device 2, a feeding device, and a curing device 4. The conveying device 1 is configured to sequentially convey a carrier 100 carrying a first workpiece to a dispensing station, an assembly station, and a curing station. The dispensing device 2 includes a dispensing head 21, which is located at the dispensing station and configured to dispense adhesive onto the assembly position of the first workpiece. The feeding device includes a feeding mechanism 31 and a conveying mechanism 32, which is configured to convey a second workpiece from the feeding mechanism 31 to the assembly station and press the second workpiece onto the assembly position of the first workpiece. The curing device 4 includes a first curing lamp 41, which is located at the curing station. When the carrier 100 is located at the curing station, the first curing lamp 41 covers the carrier 100.

[0067] It is understandable that the first workpiece mentioned above is the electronic component mentioned earlier, the second workpiece mentioned above is the flexible circuit board mentioned earlier, and so on.

[0068] In this embodiment, when the conveying device 1 transports the carrier 100 to the dispensing station, the dispensing device 2 dispenses adhesive onto the first workpiece. After the dispensing device 2 completes dispensing, the conveying device 1 transports the carrier 100 to the assembly station. The loading device then transports the second workpiece to the assembly station and presses it onto the first workpiece. The conveying device 1 then transports the carrier 100 to the curing station, where the curing device 4 cures the adhesive between the first and second workpieces, thus firmly bonding them together. The dispensing and assembly equipment in this embodiment integrates the dispensing device 2, the transport device, and the curing device 4, and can complete the dispensing, pressing, and curing operations in one operation, thereby saving equipment space and improving production efficiency.

[0069] Preferably, in this embodiment, the carrier 100 holds a plurality of first workpieces. After the conveying device 1 completes one conveying cycle, a second workpiece is assembled on each of the plurality of first workpieces, thereby further improving production efficiency.

[0070] It is understood that the first curing lamp 41 in this embodiment is an ultraviolet lamp. The curing principle of the ultraviolet lamp is existing technology, and will not be described in detail in this embodiment.

[0071] Based on the above, the conveying device 1 in this embodiment includes a conveyor line 11, baffles 12, and a lifting mechanism 13. The conveyor line 11 includes a first mounting frame 111 and a pair of conveyor belts 112. The pair of conveyor belts 112 are arranged opposite to each other on both sides of the first mounting frame 111. The carrier 100 is carried on the pair of conveyor belts 112. A dispensing station, an assembly station, and a curing station are arranged at intervals along the conveying direction of the conveyor line 11. That is, in this embodiment, the carrier 100 carrying the second workpiece is sequentially conveyed to the dispensing station, the assembly station, and the curing station by the pair of conveyor belts 112. Baffles 12 are provided at the dispensing station, the assembly station, and the curing station. When the carrier 100 moves along the conveyor line... When the carrier 11 moves to any of the dispensing station, assembly station, and curing station, the carrier 100 can abut against the stop bar 12. Specifically, the stop bar 12 located at the dispensing station, assembly station, and curing station is connected to the movable end of the eighth drive member 14, which is fixedly mounted on the first mounting bracket 111. The eighth drive member 14 can drive the stop bar 12 to move along the arrangement direction of a pair of conveyor belts 112, so that the stop bar 12 can move to the moving path of the carrier 100 or away from the moving path of the carrier 100, thereby blocking the carrier 100 to the dispensing station, assembly station, or curing station, or allowing the carrier 100 to continue to be conveyed along the conveyor line.

[0072] It is understood that the eighth driving component 14 in this embodiment can be any of the linear drive structures such as a cylinder or an electric push rod, and this embodiment does not impose any specific restrictions on it.

[0073] When the carrier 100 is blocked at the dispensing station, assembly station, or curing station, the pair of conveyor belts 112 are still running at this time, so the pair of conveyor belts 112 will still generate friction on the carrier 100. This will not only cause the carrier 100 to be unable to be stably maintained at the dispensing station, assembly station, or curing station, but will also damage the conveyor belts 112. To solve the above problems, in this embodiment, a lifting mechanism 13 is provided at the dispensing station, assembly station, and curing station. The lifting mechanism 13 is configured to lift the carrier 100 so that the carrier 100 is away from the conveyor line 11. That is, when the carrier 100 is blocked at the dispensing station, assembly station, or curing station, the lifting mechanism 13 can lift the carrier 100 away from the pair of conveyor belts 112.

[0074] Furthermore, the lifting mechanism 13 in this embodiment includes a second lifting plate 131 and a seventh driving member 132. The seventh driving member 132 is fixedly mounted on the first mounting bracket 111, while the second lifting plate 131 is slidably connected to the first mounting bracket 111. Simultaneously, the second lifting plate 131 is fixedly connected to the movable end of the seventh driving member 132, and the seventh driving member 132 is configured to drive the second lifting plate 131 to rise and fall vertically. It is understood that the seventh driving member 132 in this embodiment can be any linear drive structure such as a cylinder or an electric push rod; no specific limitation is made in this embodiment. The second lifting plate 131 is provided with at least two protrusions 1311. When the carrier 100 moves along the conveyor line 11 to the dispensing station, assembly station or curing station, the carrier 100 is located directly above the second lifting plate 131. The at least two protrusions 1311 are directly opposite to the at least two positioning holes on the carrier 100. After the second lifting plate 131 rises a certain distance in the vertical direction, the at least two protrusions 1311 can be inserted into the at least two positioning holes on the carrier 100 to position the carrier 100, thereby preventing the carrier 100 from shaking during the dispensing, assembly or curing operation. When the second lifting plate 131 continues to rise, the carrier 100 is lifted away from the pair of conveyor belts 112.

[0075] It is understood that the second lifting plate 131 in this embodiment is also provided with an adsorption hole 1312, which is connected to a vacuum generator (not shown in the figure) to adsorb the carrier 100 onto the second lifting plate 131, thereby further preventing the carrier 100 from shaking during dispensing, assembly or curing operations.

[0076] Preferably, the dispensing device 2 in this embodiment further includes a first visual inspection element 24, a laser head 25, a first mounting plate 26, and a ninth driving element 27. The first visual inspection element 24, the laser head 25, and the dispensing head 21 are all slidably connected to the first mounting plate 26 via a first connecting plate 28. The first visual inspection element 24 is used to acquire an image of the upper surface of the first workpiece carried on the carrier 100 located at the dispensing station, so as to ensure that the dispensing head 21 can accurately dispense glue to the assembly position of the second workpiece. The laser head 25 is used to detect the vertical distance between the dispensing head 21 and the first workpiece carried on the carrier 100 located at the dispensing station, so as to ensure that when the glue dripped from the dispensing head 21 falls on the first workpiece, its shape meets the requirements. The ninth driving element 27 is used to drive the first connecting plate 28 to move relative to the first mounting plate 26 in the vertical direction, so as to adjust the position of the dispensing head 21 in the vertical direction according to the distance detected by the laser head 25.

[0077] It is understood that the ninth driving component 27 in this embodiment is a rodless cylinder. Of course, in other optional embodiments, the ninth driving component 27 may also be other types of cylinders or electric push rods and other linear drive structures. This embodiment does not make specific limitations on this.

[0078] Furthermore, the dispensing device 2 in this embodiment also includes an electronic scale 22 and a third driving member (not shown in the figure). The third driving member is configured to move the dispensing head 21 from the dispensing station to above the electronic scale 22. The dispensing head 21 can dispense adhesive onto the weighing pan of the electronic scale 22. The electronic scale 22 is configured to detect the weight of the adhesive liquid dripped from the dispensing head 21 onto the weighing pan, thereby detecting whether the amount of adhesive liquid dripped from the dispensing head 21 meets the requirements, thereby further ensuring that the first workpiece and the second workpiece can be firmly bonded together after the adhesive liquid is cured.

[0079] It is understandable that the third driving component in this embodiment needs to periodically move the dispensing head 21 from the dispensing station to above the electronic scale 22, so as to periodically check whether the amount of adhesive dripped from the dispensing head 21 meets the requirements.

[0080] Since some adhesive residue adheres to the dispensing nozzle of the dispensing head 21 after each dispensing, if the adhesive residue is not cleaned from the dispensing nozzle, the dispensing nozzle of the dispensing head 21 will be blocked. To solve the above problem, the dispensing device 2 in this embodiment also includes a blowing assembly. The blowing assembly is configured to blow air onto the dispensing head 21. The dispensing assembly includes a blower head 231 and an air source (not shown in the figure). After the dispensing head 21 dispenses adhesive onto the electronic scale 22 or onto a preset number of first workpieces carried on the carrier 100, the third driving member can drive the dispensing head 21 to move above the blower head 231. The blower head 231 blows air onto the dispensing head 21 to clean the adhesive residue adhering to the dispensing nozzle of the dispensing head 21. It can be understood that the preset number can be one or more, and the specific value is set according to the actual working conditions. This embodiment does not impose a specific limitation on this.

[0081] Furthermore, the loading mechanism 31 includes a second mounting frame 316, a first bearing plate 311, and a first conveying component 312. The first bearing plate 311 is disposed at the loading station, and multiple trays carrying second workpieces are stacked on the first bearing plate 311. The first conveying component 312 is configured to transport the uppermost tray from the loading station to the unloading station. After the conveying mechanism 32 has removed all the second workpieces from the uppermost tray, the first conveying component 312 transports the uppermost tray to the unloading station. It can be understood that a second bearing plate 317 is disposed at the unloading station in this embodiment, and empty trays can be stacked on the second bearing plate 317. Both the first bearing plate 311 and the second bearing plate 317 are slidably connected to the second mounting frame 316, and the first bearing plate 311 and the second bearing plate 317 are slidably connected to the second mounting frame 316. Each of the 317 is equipped with a handle 3111. After all the trays on the first bearing plate 311 have been moved to the unloading station by the first conveying component 312, the operator can pull the handle 3111 on the first bearing plate 311 to slide the first bearing plate 311 away from the loading station. The operator can then place multiple trays fully loaded with the second workpieces back onto the first bearing plate 311 and push the first bearing plate 311 to the loading station using the handle 3111. At the same time, the operator can pull the handle 3111 on the second bearing plate 317 to slide the second bearing plate 317 away from the unloading station. The operator can then remove multiple empty trays from the second bearing plate 317 and push the second bearing plate 317 to the unloading station using the handle 3111.

[0082] Optionally, the second mounting bracket 316 is provided with a slide rail 3161, and the loading station and unloading station are spaced apart along the extension direction of the slide rail 3161. The first conveying component 312 includes a tenth driving component 3121, a first frame 3122, a second frame 3123, and a plurality of first suction nozzles 3124. The plurality of first suction nozzles 3124 are fixedly installed on the first frame 3122. The first frame 3122 is slidably connected to the second frame 3123 in the vertical direction and fixedly connected to the movable end of the tenth driving component 3121. 121 is fixedly installed on the second frame 3123, and the second frame 3123 is slidably connected to the slide rail 3161. The second frame 3123 can slide along the slide rail 3161 between the loading station and the unloading station. When the second frame 3123 is in the loading station, the tenth drive member 3121 can drive the first frame 3122 to rise and fall in the vertical direction so that the multiple first suction nozzles 3124 can contact the uppermost one of all the material trays in the loading station and pick up the material tray so as to transport the material tray from the loading station to the unloading station.

[0083] It is understood that the tenth driving component 3121 in this embodiment can be any linear drive structure such as a cylinder or an electric push rod, and this embodiment does not impose any specific restrictions on it.

[0084] Furthermore, the feeding mechanism 31 in this embodiment also includes multiple pallets 313, a first lifting plate 314, and a second driving member 315. Three of the pallets 313 are arranged in a triangular pattern, meaning three of the multiple pallets 313 are arranged in a triangular pattern. The upper surfaces of the multiple pallets 313 are located in the same horizontal plane. All pallets 313 are correspondingly connected to the first driving member 3131, which is fixedly mounted on the second mounting bracket 316. The first driving member 3131 is configured to drive the pallets 313 to move horizontally toward or away from the trays located at the feeding station, so that the pallets 313 can support the uppermost of all the trays located at the feeding station. The first working position and the second working position away from the material tray are configured to drive the first lifting plate 314 to lift all the material trays located at the loading station, and make the lower surface of the uppermost material tray in the loading station flush with the upper surface of the pallet 313. When all pallets 313 are in the first working position, the uppermost material tray in the loading station is supported on multiple pallets 313. Since the upper surfaces of multiple pallets 313 are in the same horizontal plane, the material tray supported on multiple pallets 313 is in a horizontal state, thereby ensuring that the conveying mechanism 32 can accurately move all the second workpieces in the material tray away from the material tray.

[0085] It is understood that the first driving component 3131 in this embodiment can be any linear driving structure such as a cylinder or an electric push rod, and the second driving component 315 can be any driving structure such as a stepper motor or a servo motor. In this embodiment, there are no specific restrictions on the structure of the first driving component 3131 and the second driving component 315.

[0086] Initially, the second driving member 315 drives the first lifting plate 314 to rise vertically a certain distance. The first lifting plate 314 lifts all the trays located at the loading station and makes the lower surface of the uppermost tray flush with the upper surface of the pallet 313. The first driving member 3131 drives the pallet 313 to move to the first working position. After the conveying mechanism 32 removes all the second workpieces in the tray, the first conveying member 312 transports the tray to the unloading station. The first driving member 3131 drives the pallet 313 to move to the second working position. Then, the second driving member 315 drives the first lifting plate 314 to rise vertically a preset distance, which is equal to the height of the tray, so that the lower surface of the next tray is flush with the upper surface of the pallet 313. The first driving member 3131 drives the pallet 313 to move to the first working position. Understandably, the second drive unit 315 can drive the first lifting plate 314 to rise a preset distance vertically after each time the pallet 313 changes from the first working position to the second working position, until all the material trays located at the loading station are transported to the unloading station.

[0087] Understandably, the second mounting bracket 316 is also equipped with a photoelectric switch 3162 consisting of a transmitter and a receiver. The photoelectric switch 3162 is used to detect whether the lower surface of the uppermost of all the material trays located at the feeding station is in the horizontal plane.

[0088] In this embodiment, two first lifting plates 314 are provided, and the two first lifting plates 314 are respectively located on both sides of the first bearing plate 311. The arrangement direction of the two first lifting plates 314 is perpendicular to the sliding direction of the first bearing plate 311. The second driving member 315 is fixedly installed on the second mounting bracket 316. Screw blocks 3141 are fixedly connected to both first lifting plates 314. The movable end of the second driving member 315 is driven by two lead screws 3151 extending in the vertical direction. The two screw blocks 3141 are screwed to the two lead screws 3151 one by one. The second driving member 315 drives the first lifting plates 314 to rise and fall in the vertical direction through the screw blocks 3141 and the lead screws 3151.

[0089] Furthermore, in this embodiment, two third lifting plates 318 are provided on both sides of the second support plate 317. The arrangement direction of the two third lifting plates 318 is perpendicular to the sliding direction of the second support plate 317. An eleventh driving member 319 is fixedly installed on the second mounting bracket 316. The eleventh driving member 319 is also connected to the two third lifting plates 318 through a ball screw structure to drive the two third lifting plates 318 to rise and fall vertically. Initially, the two third lifting plates 318 are located above the second support plate 317. When the first conveying member 312 transports an empty tray to the unloading station, all the first suction nozzles 3124 stop suction, and the tray falls onto the two third lifting plates 318. Then the eleventh driving member 319... The driving component 319 drives the two third lifting plates 318 to descend, and the descent distance is equal to the height of the material tray. Subsequently, the first conveying component 312 transports the empty material trays to the unloading station one by one, and stacks the empty material trays onto the third lifting plates 318 one by one. After each time the first conveying component 312 transports the empty material tray to the unloading station and stacks the material tray onto the third lifting plate 318, the pair of third lifting plates 318 descends by the height of one material tray. When all the material trays located at the loading station have been transported to the unloading station and stacked onto the third lifting plates 318, the pair of third lifting plates 318 descends to be flush with the second bearing plate 317, and the empty material trays stacked on the third lifting plates 318 are then supported on the second bearing plate 317.

[0090] It is understood that the eleventh driving component 319 in this embodiment can be any of the driving structures such as a stepper motor or a servo motor, and no specific restrictions are imposed on it in this embodiment.

[0091] Preferably, the conveying mechanism 32 in this embodiment includes a first platform 321, a pressing block 322, a second conveying component 324, and a third conveying component 325. The first platform 321 is provided with a first receiving groove 3211, which is configured to receive the second workpiece. An opening is provided on one side of the first receiving groove 3211. The pressing block 322 is connected to the movable end of the fourth driving component 323. The fourth driving component 323 is configured to drive the pressing block 322 to move toward or away from the opening. The second conveying component 324 can convey the second workpiece from the feeding mechanism 31 to the first platform 321. The third conveying component 325 is configured to convey the second workpiece from the first platform 321 to the assembly station and press the second workpiece into the assembly position of the first workpiece. The pressing block 322 cooperates with the first receiving groove 3211 of the first platform 321 to perform secondary positioning of the second workpiece, so that the third conveying component 325 can blindly pick up the second workpiece at the first platform 321.

[0092] Further, in this embodiment, the second conveying component 324 includes a second suction cup 3241, a second mounting plate 3242, a twelfth driving component 3243, and a thirteenth driving component 3244. The second suction cup 3241 is fixedly connected to the second connecting plate 3245, and the second connecting plate 3245 is slidably connected to the second mounting plate 3242 in a vertical direction. A pressure sensor 3246 and a buffer spring 3247 are also provided between the second connecting plate 3245 and the second mounting plate 3242. The second mounting plate 3242 is fixedly connected to the movable end of the twelfth driving component 3243, and the twelfth driving component 3243 is used to drive the second mounting plate 3242. The second suction cup 3241 is rotated around its axis to adjust its position and orientation, so as to ensure that the second suction cup 3241 can accurately adsorb the second workpiece in the material tray at the loading station. At the same time, it can also adjust the position and orientation of the second workpiece adsorbed by the second suction cup 3241 to ensure that the second workpiece can be placed in the first receiving groove 3211. The thirteenth driving member 3244 is configured to drive the twelfth driving member 3243 and the second mounting plate 3242 to rise and fall in the vertical direction, thereby driving the second suction cup 3241 to rise and fall in the vertical direction to adsorb the second workpiece in the material tray at the loading station, or to place the second workpiece in the first receiving groove 3211. In this embodiment, the pressure sensor 3246 is used to detect the pressure between the second suction nozzle 3248 and the second suction cup 3241 and the second workpiece when the second suction nozzle 3248 and the second suction cup 3241 are adsorbing the second workpiece located in the material tray at the loading station, thereby avoiding damage to the second workpiece. The buffer spring 3247 is connected or abutted between the second connecting plate 3245 and the second mounting plate 3242 to avoid the second suction nozzle 3248 and the second suction cup 3241 from making hard contact with the second workpiece.

[0093] It is understood that the twelfth driving component 3243 in this embodiment can be any type of driving structure such as a stepper motor or a servo motor, and no specific limitation is made in this embodiment. Similarly, it is understood that the thirteenth driving component 3244 in this embodiment is a rodless cylinder. Of course, in other optional embodiments, the thirteenth driving component 3244 can also be other types of cylinders or linear drive structures such as electric push rods, and no specific limitation is made in this embodiment.

[0094] Since the flexible circuit board includes not only parts with high hardness but also flexible parts with low hardness, in order to ensure that the second transport member 324 can accurately place the second workpiece into the first receiving groove 3211, the second transport member 324 in this embodiment also includes a second suction nozzle 3248. The second suction nozzle 3248 is used to adsorb the flexible parts of the second workpiece. The second suction nozzle 3248 and the second suction cup 3241 are both fixedly connected to the second connecting plate 3245.

[0095] Preferably, the second transporter 324 in this embodiment further includes a second vision detection element 3249, which is used to acquire images of the tray located at the loading station and the second platform 326, so as to ensure that the second suction cup 3241 can accurately adsorb the second workpiece in the tray located at the loading station, and can further ensure that the second workpiece can be placed in the first receiving groove 3211.

[0096] In the prior art, flexible circuit boards generally have a protective cover. The protective cover is fastened to the flexible circuit board and covers the outer periphery of the assembly position on the flexible circuit board to protect the assembly position. Therefore, before the third transport member 325 transports the second workpiece on the first platform 321, the protective cover on the second workpiece needs to be removed. For this purpose, the dispensing assembly equipment in this embodiment also includes a protective cover peeling device. The bottom of the first receiving groove 3211 is provided with a through hole (not shown in the figure), through which the protective cover fastened to the second workpiece can be exposed. The protective cover peeling device includes a first clamping block 5. 1. A second clamping block 52, a fifth driving member 53, and a sixth driving member 54. The first clamping block 51 and the second clamping block 52 are disposed below the first platform 321. The fifth driving member 53 is configured to drive the first clamping block 51 and the second clamping block 52 to move relative to each other to clamp the protective cover. The sixth driving member 54 is configured to drive the fifth driving member 53, the first clamping block 51, and the second clamping block 52 to move up and down in the vertical direction. After the first clamping block 51 and the second clamping block 52 clamp the protective cover, the sixth driving member 54 causes the first clamping block 51 and the second clamping block 52 to descend in the vertical direction and move away from the second workpiece to peel the protective cover off the second workpiece.

[0097] It is understood that the fifth driving component 53 in this embodiment is a rodless cylinder. Of course, in other optional embodiments, the fifth driving component 53 may also be other types of cylinders or electric push rods and other linear drive structures. The sixth driving component 54 may be a cylinder or electric push rod and other linear drive structures. In this embodiment, the structure of the fifth driving component 53 and the sixth driving component 54 is not specifically limited.

[0098] Furthermore, the protective cover peeling device in this embodiment also includes a discharge channel 55, which is located below the first clamping block 51 and the second clamping block 52. When the sixth driving member 54 causes the first clamping block 51 and the second clamping block 52 to descend vertically and move away from the second workpiece, and peels the protective cover off the second workpiece, the fifth driving member 53 drives the first clamping block 51 and the second clamping block 52 to move away from each other, so that the peeled protective cover falls into the discharge channel 55 from one end. The other end of the discharge channel 55 is connected to a vacuum pump (not shown in the figure) to apply suction to the peeled protective cover and make the peeled protective cover flow along the discharge channel 55 into the waste bin (not shown in the figure).

[0099] The conveying mechanism 32 in this embodiment also includes a second platform 326. The second platform 326 is provided with a plurality of second receiving slots 3261. The second receiving slots 3261 are configured to receive the second workpiece. The second conveying member 324 can convey the second workpiece from the loading mechanism 31 to the second platform 326, or convey the second workpiece from the second platform 326 to the first platform 321. That is, the second conveying member 324 in this embodiment can buffer the second workpiece on the second platform 326, or convey the second workpiece buffered on the second platform 326 to the first platform 321.

[0100] Based on the foregoing description, the third transport component 325 in this embodiment includes a first suction cup 3251, a second curing lamp 3252, a third mounting plate 3253, a fourteenth driving component 3254, and a fifteenth driving component 3255. The first suction cup 3251 is configured to pick up the second workpiece. Both the first suction cup 3251 and the second curing lamp 3252 are fixedly mounted on the third mounting plate 3253. The third mounting plate 3253 is fixedly connected to the movable end of the fourteenth driving component 3254, which drives the third mounting plate 3253 to rotate around its axis. The first suction cup 3251 is moved to adjust its position, ensuring that it can accurately adsorb the second workpiece located in the first receiving groove 3211. It can also adjust the position of the second workpiece adsorbed by the first suction cup 3251 to ensure that the assembly position of the second workpiece is aligned with the assembly position of the first workpiece. The fifteenth driving member 3255 is configured to drive the fourteenth driving member 3254 and the third mounting plate 3253 to move up and down in the vertical direction, thereby driving the first suction cup 3251 to move up and down in the vertical direction, thus pressing the second workpiece onto the first workpiece.

[0101] Furthermore, the second curing lamp 3252 includes a plurality of first lamp beads 32521, which are arranged on the outer periphery of the first suction cup 3251. The second curing lamp 3252 is an ultraviolet lamp. The second curing lamp 3252 can pre-cure the adhesive on the first workpiece before pressing the second workpiece onto the first workpiece, so as to ensure that the adhesive on the first workpiece has a certain viscosity, thereby preventing the first workpiece and the second workpiece from moving relative to each other during the process of the conveying device 1 transporting the carrier 100 from the assembly station to the curing station.

[0102] Based on the above, the third transport component 325 in this embodiment also includes a third suction nozzle 3256, which is used to adsorb the flexible part of the second workpiece. The second suction nozzle 3248, the first suction cup 3251, and the second curing lamp 3252 are all fixedly installed on the third mounting plate 3253.

[0103] Preferably, the dispensing assembly equipment in this embodiment further includes a third curing lamp 6. The third curing lamp 6 is disposed at the assembly station and located below a pair of conveyor belts 112. The third curing lamp 6 includes a plurality of second lamp beads 61 arranged in a circular pattern. The third curing lamp 6 is an ultraviolet lamp. The third curing lamp 6 can further pre-cure the adhesive on the first workpiece before pressing the second workpiece onto the first workpiece, so as to further ensure that the adhesive on the first workpiece has a certain viscosity, thereby further preventing the relative movement of the first workpiece and the second workpiece during the process of the conveying device 1 transporting the carrier 100 from the assembly station to the curing station.

[0104] Based on the above, the protective cover attached to the second workpiece can be exposed through the through hole, which is located at the bottom of the first receiving groove 3211. Therefore, the assembly position of the second workpiece picked up by the third transport member 325 is located below the second workpiece. In this embodiment, the dispensing assembly equipment also includes a third vision inspection member 7 and a waste collection box 8. After picking up the second workpiece located on the first stage 321, the third transport member 325 can move the second workpiece above the third vision inspection member 7. The third vision inspection member 7 can acquire an image of the assembly position located below the second workpiece, thereby detecting whether the second workpiece is qualified. If the second workpiece is unqualified, the third transport member 325 will move the second workpiece above the waste collection box 8 and place the second workpiece into the waste collection box 8.
