[0002] In the production process of existing display devices, the punched screen has become the mainstream screen design of smart phones. The punched screen is to punch a small hole in the middle or on the side of the mobile phone screen and add a camera. In this way, the screen-to-body ratio of the entire mobile phone will become very high, and it does not affect the use. Compared with the current notch screen, the punched screen can not only increase the screen-to-body ratio, but also ensure the tightness and waterproofness of the mobile phone. In the existing punching technology, the laser punching method is usually used to perform the laser punching process on the workpiece to complete the processing and manufacturing of the punched workpiece. Before the laser punching process, the loading process is usually required. How to achieve efficient loading of the workpiece is a technical problem to be solved. Therefore, it is necessary to study a workpiece loading device and a loading method thereof to address the deficiencies of the existing technology and solve or mitigate one or more of the above problems.

These adsorption and positioning methods form a combined design, which is one of the main inventive concepts of this application. This combined design of adsorption and positioning not only considers the size of the workpiece to ensure the repeat positioning accuracy during the adsorption and handling of the workpiece, but also takes into account the adjustment of the workpiece position by the first carrier assembly and the first carrier assembly. It reasonably considers the flexibility of the workpiece itself and the processing characteristics of laser processing, and optimizes and improves the laser drilling accuracy and efficiency of the workpiece.

[0038] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned technical effects simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0055] Such as Figure 1As shown in the figure, the present invention provides a loading device, which includes a loading mechanism 1, a manipulator 2, a flipping mechanism 3, a first carrier assembly 4, a handling mechanism 5, a second carrier assembly 6, and a detection mechanism 7. The manipulator 2 is located between the loading mechanism 1 and the flipping mechanism 3. The flipping mechanism 3 and the first carrier assembly 4 are located between the manipulator 2 and the second carrier assembly 6. The flipping mechanism 3, the first carrier assembly 4, the handling mechanism 5, the second carrier assembly 6, and the detection mechanism 7 are substantially in the same straight line direction. Each mechanism will be elaborated in detail below.

[0056] (1) Loading mechanism

[0057] As Figure 2 and Figure 3 shown in the figure, the loading mechanism is used to load a number of full Tray trays filled with workpieces for the manipulator to pick up the workpieces, and place and unload the empty Tray trays formed after the manipulator picks up the workpieces. The loading mechanism 1 includes a first Tray tray moving channel, a second Tray tray moving channel, a first rack 8, a first lifting assembly, a second lifting assembly, a first group of suction cup assemblies, a second group of suction cup assemblies, a Tray tray transfer part, and a Tray tray separation component.

[0058] The first rack 8 is in a frame structure, which is provided with the first Tray tray moving channel and the second Tray tray moving channel. The first Tray tray moving channel is provided with a first Tray tray placement area, where a number of full Tray trays filled with workpieces are placed. The second Tray tray moving channel is provided with a second Tray tray placement area, which is used to place a number of empty Tray trays. The Tray tray filled with workpieces can be simply referred to as a full Tray tray, and the Tray tray without any workpieces can be simply referred to as an empty Tray tray. A number of full Tray trays in the first Tray tray placement area are stacked. The first Tray tray moving channel is used for the movement of a number of full Tray trays filled with workpieces, and moves a number of full Tray trays filled with workpieces to the first Tray tray placement area for the manipulator to pick up the workpieces; the empty Tray trays formed after the manipulator picks up the workpieces can be stacked in the second Tray tray placement area. Specifically, the empty Tray trays formed after the manipulator picks up the workpieces are transferred and stacked in the second Tray tray placement area. The second Tray tray moving channel is used to unload a number of stacked empty Tray trays.

[0059] A first fixing bracket 13 is formed at the rear part of the first rack 8. A first lifting assembly 15 and a second lifting assembly 16 are respectively installed on the first fixing bracket 13. The first lifting assembly 15 includes a first carrier 151 and a first lifting part. The first carrier is used to carry a number of Tray trays filled with workpieces. The first lifting part moves up and down to lift a number of full Tray trays filled with workpieces to the working range of the manipulator 2, so that the manipulator 2 can pick up the workpieces on the full Tray trays. The second lifting assembly 16 includes a second carrier and a second lifting part. The second carrier is used to carry empty Tray trays. The second lifting part moves up and down to receive the empty Tray trays after the manipulator 2 picks up the workpieces (it should be noted that it also requires subsequent transfer processes, etc.).

[0060] A second fixing bracket 14 is formed in the middle of the first rack 8. The second fixing bracket 14 is perpendicular to the first Tray tray moving channel and the second Tray tray moving channel. A driving part, a first guide rail and a first slider are provided on the first fixing bracket 13. The driving part drives the first slider to move linearly on the first guide rail, and the driving part can adopt a conventional motor. A second guide rail and a second slider 171 are provided on the second fixing bracket 14. One side of the Tray tray transfer part 17 is slidably connected to the second guide rail, and the other side of the Tray tray transfer part 17 is slidably connected to the first guide rail. Specifically, one side of the Tray tray transfer part 17 is slidably connected to the second guide rail through the second slider, and the other side of the Tray tray transfer part 17 is slidably connected to the first guide rail through the first slider. The Tray tray transfer part 17 includes a first transfer connecting piece 172, a second transfer connecting piece 175, a transfer table 173 and a regularizing component 174. The regularizing component 174 includes a telescopic cylinder and a regularizing hook. The regularizing component 174 is arranged around the transfer table 173, and the regularizing component 174 moves to adjust the position of the empty Tray tray on the transfer table. The transfer table 173 is connected to the second slider through the first transfer connecting piece 172, and the transfer table 173 is connected to the first slider through the second transfer connecting piece 175. After the Tray tray is placed on the transfer table 173, the regularizing component 174 is arranged around the transfer table 173. The telescopic parts of the four regularizing components 174 move telescopically to drive the regularizing hooks to move and adjust the position of the Tray tray on the transfer table 173. The telescopic part can adopt a conventional cylinder, etc.

[0061] A first suction cup assembly 181 is provided on the first fixing bracket 13. Specifically, the first suction cup assembly 181 is installed on the first fixing bracket 13, and a plurality of first suction cup assemblies 181 are provided, for example Figure 2Two of them, the first suction cup assembly 181 includes a first suction cup mounting bracket, a first telescopic part, a first suction cup support 1811, a first suction cup adjustment bracket and a first suction cup 1812. The first suction cup mounting bracket is mounted on the first fixing bracket 13. The first telescopic part drives the first suction cup support and the first suction cup adjustment bracket to move up and down. The first suction cup is adjustably mounted on the first suction cup adjustment bracket. A second suction cup assembly 182 is provided on the second fixing bracket 14. Specifically, the second suction cup assembly 182 is mounted on the second fixing bracket 14. There are multiple second suction cup assemblies 182, for example Figure 2 Two of them, the second suction cup assembly 182 includes a second suction cup mounting bracket, a second telescopic part, a second suction cup support, a second suction cup adjustment bracket and a second suction cup. The second suction cup mounting bracket is mounted on the second fixing bracket 14. The second telescopic part drives the second suction cup support and the second suction cup adjustment bracket to move up and down. The second suction cup is adjustably mounted on the second suction cup adjustment bracket. The difference between the two suction cup assemblies is that the installation height of the first suction cup assembly is slightly different from that of the second suction cup assembly because it needs to avoid the first lifting assembly and the second lifting assembly. On this basis, the first group of suction cup assemblies includes the first suction cup assembly 181 on one side and the second suction cup assembly 182 on the opposite side. The first group of suction cup assemblies is used to adsorb and place an empty Tray tray on the Tray tray transfer part 17. Specifically, the first group of suction cup assemblies is used to adsorb and place an empty Tray tray on the transfer table 173. The second group of suction cup assemblies includes the first suction cup assembly 181 on the other side and the second suction cup assembly 182 on the opposite side. The second group of suction cup assemblies is used to adsorb and lift an empty Tray tray and to place the adsorbed empty Tray tray on the second lifting assembly. Specifically, the second group of suction cup assemblies is used to adsorb an empty Tray tray and place it on the second carrier or on the already placed empty Tray tray.

[0062] Tray tray separation assemblies 19 are respectively provided on the first racks 8 on both sides of the first Tray tray placement area, as Figure 5 shown. The Tray tray separation assembly 19 includes a telescopic part 191, a mounting part 192 and a separation part 193. Multiple groups of Tray tray separation assemblies are mounted on the first rack 8, for example, two groups in the figure. Among them, the separation part 193 can adopt a conventional separation block or separation plate or separation piece. The number of separation parts is multiple, for example, 2 in the figure. Multiple separation parts 193 are horizontally mounted on the mounting part 192 and are connected to the mounting part 193. Under the action of the telescopic part 191, the separation part 193 extends to approach the full Tray tray filled with workpieces or retracts to be away from the full Tray tray. Specifically, the separation parts 193 of the two groups of symmetrically arranged Tray tray separation assemblies 19 in the figure extend to approach the full Tray tray filled with workpieces or are away from the full Tray tray. Each group of Tray tray separation assemblies 19 includes two separation parts 193.

[0063] When the loading mechanism is working, the separation part 193 extends under the action of the telescopic part 191 to approach the full Tray tray, and inserts between the topmost full Tray tray and the adjacent sub-topmost full Tray tray. Such an insertion method is very beneficial, which can play a role in fixing and limiting the full Tray trays below the sub-topmost layer. When the manipulator 2 sucks the workpieces on the topmost full Tray tray and / or the first group of suction cup components adsorb the topmost empty Tray tray, the Tray tray separation component 19 can ensure that the manipulator and / or the first group of suction cup groups can only act on the topmost full Tray tray and / or empty Tray tray. The suction operation of the manipulator and / or the adsorption operation of the first group of suction cup components will not drive the full Tray trays below the sub-topmost layer or below the sub-topmost layer, avoiding changing the height position of the full Tray trays below the sub-topmost layer or below the sub-topmost layer, so as to ensure the accurate working position of each full Tray tray during the operation of the loading mechanism and the smooth adsorption operation process.

[0064] When the loading mechanism is working, the first lifting part of the first lifting component 15 moves up and down, lifting several full Tray trays filled with workpieces to the working range of the manipulator 2. The manipulator 2 sucks the workpieces on one full Tray tray, and one full Tray tray filled with workpieces becomes an empty Tray tray. The first group of suction cup components moves up and down to adsorb an empty Tray tray. The Tray tray transfer part 17 moves under an empty Tray tray, that is, under the first suction cup component. The first group of suction cup components places an empty Tray tray on the Tray tray transfer part 17. Specifically, it is placed on the transfer table 173 of the Tray tray transfer part. The Tray tray transfer part for transferring an empty Tray tray moves under the second group of suction cup components. The second group of suction cup components adsorb an empty Tray tray. The Tray tray transfer part leaves from under the second group of suction cup components. The second group of suction cup components places an empty Tray tray on the second carrier or on the already placed empty Tray trays. In this way, the feeding of the workpieces on the Tray tray and the placement, stacking and discharging and recycling of the empty Tray trays are realized, and the degree of automation of the whole feeding and Tray tray recycling is high.

[0065] When the loading mechanism is working, for several full Tray trays filled with workpieces in the first Tray tray placement area, after the first group of suction cup assemblies lift and adsorb an empty Tray tray or after the first group of suction cup assemblies place an empty Tray tray on the Tray tray transfer part 17, specifically, after placing it on the transfer table 173 of the Tray tray transfer part. The first lifting assembly 15 raises the working height of one Tray tray. Specifically, the first lifting part of the first lifting assembly 15 raises the working height of one Tray tray so that the manipulator 2 can pick up the workpieces on the next full Tray tray; for the second Tray tray placement area, the second group of suction cup assemblies place an empty Tray tray on the second carrier or on the already placed empty Tray trays. Each time an empty Tray tray is placed, the second lifting assembly 16 correspondingly lowers the working height of one Tray tray. Specifically, the second lifting part of the second lifting assembly 16 correspondingly lowers the working height of one Tray tray. This cycle continues until there are no Tray trays on the first carrier of the first lifting assembly and several empty Tray trays are stacked on the second carrier of the second lifting assembly, completing a loading work process. Obviously, after a loading work process, the total number of full Tray trays filled with workpieces placed in the first Tray tray placement area before loading is equal to the total number of empty Tray trays placed in the second Tray tray placement area after the loading work process is completed.

[0066] When the loading mechanism is working, several first traveling rollers 11 are provided in the first Tray tray moving channel, which are used to move the full Tray trays loaded with workpieces to a position close to the manipulator 2 so that the manipulator 2 can pick up the workpieces on the full Tray trays. Several second traveling rollers 12 are provided in the second Tray tray moving channel, which are used to move several stacked empty Tray trays after the workpieces are taken away to the outer end of the loading mechanism so that several stacked empty Tray trays can be removed by manpower or external force equipment, realizing the unloading of several empty Tray trays. The first carrier can move to a position lower than the first traveling rollers 11 for the movement of full Tray trays, and the first carrier can move to a position lower than the second traveling rollers 12 for the movement of full Tray trays.

[0067] (2) Manipulator

[0068] The manipulator sucks the workpieces conveyed by the feeding mechanism and places the workpieces on the flipping mechanism or the first carrier assembly. The manipulator 2 is used to adsorb the workpieces on the feeding mechanism. There is one manipulator 2, which is placed on the flipping mechanism or the first carrier assembly. The technology of the manipulator is relatively mature in the art, and the present invention does not make excessive limitations. It is only limited that a vacuum adsorption assembly is provided at the end of the manipulator. The vacuum adsorption assembly generally includes a vacuum device and several suction cups. By controlling the on / off of the vacuum device, the adsorption or non-adsorption of the workpieces by the several suction cups is controlled. These belong to conventional prior arts and are not elaborated in the present invention.

[0069] (3) Flipping mechanism

[0070] Such as Figure 1 、 Figure 2 And Figure 6 As shown, the flipping mechanism is used to flip the workpieces that need to be flipped and then place them on the first carrier assembly; the feeding device further includes a flipping mechanism and a frame S. The flipping mechanism 3 is arranged on the frame S. The flipping mechanism 3 is arranged between the manipulator 2 and the first carrier assembly 4, and the flipping mechanism 3 can form a position match with the first carrier assembly 4.

[0071] The flipping mechanism 3 includes a fixedly arranged flipping bracket 31, a flipping motor 32, a mounting member 33, and a third lifting assembly 34. The flipping bracket 31 is fixedly arranged on the frame S, and the third lifting assembly 34 moves up and down on the flipping bracket 31. The third lifting assembly 34 includes a third lifting part 341 and a bearing part 342. The third lifting part 341 is slidably matched with the flipping bracket 31 up and down. The bearing part 342 is formed on the third lifting part 341. The bearing part 342 is used to mount the flipping motor 32 and the mounting member 33. The flipping motor 32 is arranged horizontally and lying on its side at the top of the bearing part 342. The output shaft of the flipping motor 32 is fixedly connected to the mounting member 33. The flipping motor 32 can perform a 180-degree flip, thereby driving the mounting member 33 to achieve a 180-degree flip. In the figure, the number of flipping motors 32 is two, and the number of mounting members 33 is also two. The output shaft of each flipping motor 32 is fixedly connected to each mounting member 33 correspondingly.

[0072] The mounting member 33 has a frame structure and is placed horizontally. It includes a first long strip portion 335, a second long strip portion 336, a first mounting portion 331, a second mounting portion 332, a third mounting portion 333, and a fourth mounting portion 334. The first long strip portion 335 is provided with a plurality of first through grooves, and the second long strip portion 336 is provided with a plurality of second through grooves. The two sides of the first mounting portion 331, the second mounting portion 332, the third mounting portion 333, and the fourth mounting portion 334 are adjustably mounted on the first through grooves and the second through grooves respectively. A first set of suction cups is adjustably mounted on the first mounting portion 331, a second set of suction cups is adjustably mounted on the second mounting portion 332, a third set of suction cups is adjustably mounted on the third mounting portion 333, and a fourth set of suction cups (not shown) is adjustably mounted on the fourth mounting portion 334. Each set of suction cups includes a plurality of suction cups. At least two sets of suction cups among the first set of suction cups, the second set of suction cups, the third set of suction cups, and the fourth set of suction cups cooperate with each other. After at least two sets of suction cups are adjustably mounted and fixed in position, they adsorb and position the workpiece. For example, in the figure, the first set of suction cups, the second set of suction cups, and the third set of suction cups cooperate with each other to form a multi-point positioning method to adsorb the front, middle, and rear parts of the workpiece. Alternatively, in this application, multiple sets of mounting portions can also be provided, and each set of mounting portions is provided with a set of suction cups to form a setting of multiple sets of suction cups. The setting of multiple sets of suction cups is completely necessary. The cooperation of multiple sets of suction cups can be applicable to the adsorption and fixation of workpieces of different sizes, making the feeding device have a wide range of use and better flexibility.

[0073] After the manipulator 2 picks up the workpiece, it detects the workpiece to determine whether the workpiece needs to be flipped. Specifically, the detection of the workpiece is to detect whether the workpiece includes optical elements. When the optical elements are included, it is flipped, and when the optical elements are not included, it is not flipped. This is not the detection requirement of the front and back sides, and it is not the judgment of whether to flip based on the front and back sides. This is completely different from the prior art and is one of the invention points of this application.

[0074] 1) When it is detected that the workpiece needs to be flipped, the manipulator 2 places the workpiece on a plurality of mounting portions on the flipping mechanism 3. The flipping mechanism 3 flips the workpiece by 180 degrees. After the flipping is completed, the flipping mechanism 3 moves up and down itself and places the workpiece on the first carrier assembly 4. Specifically, when it is detected that the workpiece needs to be flipped, the flipping mechanism 3 rises to a suitable height position or remains stationary by itself, accepts the workpiece conveyed by the manipulator and adsorbs and fixes the workpiece. The flipping mechanism 3 flips the workpiece by 180 degrees. After the flipping is completed, it descends to a height position matching the first carrier assembly 4 and places the workpiece on the first carrier assembly 4.

[0075] 2) When it is detected that the workpiece does not need to be flipped, the flipping mechanism 3 moves up and down by itself, lifting the mounting member 33 to a certain height, thereby avoiding affecting the positional interference between the mounting member 33 and the first carrier assembly 4 and affecting the subsequent movement and handling of the workpiece by the first carrier. Specifically, the self-lifting movement of the flipping mechanism 3 is optional. When it is detected that the workpiece does not need to be flipped, the manipulator 2 places the sucked workpiece on the first carrier assembly 4.

[0076] (4) First carrier assembly

[0077] As Figure 1 、 Figure 7 、 Figure 8 shown, the first carrier assembly is used to receive the workpiece sent by the manipulator or the flipping mechanism and carry the workpiece to the handling mechanism. Specifically, the handling mechanism means that the first carrier assembly carries the workpiece to below or to one side of or close to the handling mechanism, which is clear and can be explained. The first carrier assembly 4 includes a first carrier 41, a first mounting member 42, and a carrier mounting member. The number of the first carriers 41 is two, and the number of the first mounting members 42 is two. Two first carrier guide rails 43 are provided on the frame S. First carrier sliders (not shown) are provided below both of the two first carriers 41. The first carrier sliders are slidably connected to the first carrier guide rails 43, and under the action of a driving device (such as a cylinder or a motor), the first carrier assembly 4 moves along the first carrier guide rails 43. The length direction of the first carrier guide rails 43 is perpendicular to the lifting direction of the flipping mechanism 3 itself. The two first carriers 41 are mounted on the carrier mounting member, and the first carrier assembly 4 can receive multiple workpieces at the same time. Multiple suction holes are provided on the first carrier. First mounting through grooves are provided on both sides of the first mounting member 42. Multiple first suction cup mounting parts are adjustably mounted on the first mounting through grooves on both sides respectively, and multiple groups of first mounting suction cups are adjustably mounted on the first suction cup mounting parts. Each group of first mounting suction cups includes multiple suction cups.

[0078] When it is detected that the workpiece does not need to be flipped, the first carrier assembly 4 is located on one side of the first carrier guide rail 43 away from the flipping mechanism 3 so that the manipulator 2 can place the workpiece on the two first carriers 41, and the first carrier assembly 4 carries the workpiece to below the handling mechanism 5. When it is detected that the workpiece needs to be flipped, the first carrier assembly 4 is located directly below the mounting member of the flipping mechanism 3 so that the flipping mechanism 3 can place the workpiece on the two first carriers 41, and the first carrier assembly 4 carries the workpiece to below the handling mechanism 5. When the workpiece is placed on the first carrier assembly 4, at least two groups of first mounting suction cups are adjustably mounted and fixed in position, and the first carrier and at least two groups of first mounting suction cups jointly adsorb and position the workpiece. The first carrier assembly 4 can perform XYθ movement adjustment to adjust the position of the workpiece on the first carrier assembly 4.

[0079] (5) Handling mechanism

[0080] A handling mechanism for handling workpieces on the first carrier assembly to the second carrier assembly. The handling mechanism 5 includes a second mounting member 51, a handling frame 52, and a handling lifting assembly 53. The handling mechanism 5 is mounted on the second machine frame 9. A handling guide rail is provided on the second machine frame 9. A handling slider is provided at the bottom of the handling frame 52. The handling guide rail is arranged in parallel with the first carrier guide rail 43. The handling slider is slidably arranged on the handling guide rail. The number of the second mounting members 51 is multiple, and two are shown in the figure. The handling lifting assembly 53 is connected to the second mounting member 51, and the lifting movement of the handling lifting assembly 53 drives the second mounting member 51 to perform a lifting movement.

[0081] The structure of the second mounting member 51 is similar to that of the mounting member 33. The second mounting member 51 includes a frame structure and is placed horizontally; it includes a first handling long strip portion, a second handling long strip portion, a first handling mounting portion, a second handling mounting portion, a third handling mounting portion, and a fourth handling mounting portion. The first handling long strip portion is provided with a first handling through slot, and there are multiple first handling through slots. The second handling long strip portion is provided with a second handling through slot, and there are multiple second handling through slots. The two sides of the first handling mounting portion, the second handling mounting portion, the third handling mounting portion, and the fourth handling mounting portion are respectively adjustably mounted on the first handling through slot and the second handling through slot. A first group of handling suction cups is adjustably mounted on the first handling mounting portion, a second group of handling suction cups is adjustably mounted on the second handling mounting portion, a third group of handling suction cups is adjustably mounted on the third handling mounting portion, and a fourth group of handling suction cups (not shown) is adjustably mounted on the fourth handling mounting portion. Each group of handling suction cups includes multiple suction cups. At least two groups of the first group of handling suction cups, the second group of handling suction cups, the third group of handling suction cups, and the fourth group of handling suction cups cooperate with each other. After at least two groups of handling suction cups are adjustably mounted and fixed in position, they adsorb and position the workpiece. Alternatively, in the present application, multiple groups of handling mounting portions can also be provided, and each group of handling mounting portions is provided with a group of suction cups to form a setting of multiple groups of handling suction cups. The setting of multiple groups of handling suction cups is completely necessary. The cooperation of multiple groups of handling suction cups can be applicable to the adsorption and fixation of workpieces of different sizes, making the use range and flexibility of the feeding device better.

[0082] When it is necessary to carry a workpiece, the first carrier assembly 4 carrying the workpiece moves to directly below the second mounting member 51 of the carrying mechanism 5. The carrying lifting assembly 53 moves downward by itself, driving the second mounting member 51 to move downward to adsorb the workpiece. Then the carrying lifting assembly 53 moves upward by itself, lifting the second mounting member 51 to an appropriate height. Then it moves towards the second carrier assembly 6. After reaching above the second carrier assembly 6, the carrying lifting assembly 53 moves downward and upward, thereby carrying the workpiece on the first carrier assembly 4 to the second carrier assembly 6 and returning to the first carrier assembly 4 to perform the next workpiece carrying operation. Therefore, the setting of the first carrier guide rail 43 and the carrying guide rail in this application is very important, and the first carrier guide rail 43 and the carrying guide rail are arranged in parallel.

[0083] The first carrier guide rail 43 includes: a manipulator placement work area, a flipping acceptance area, and a handover and carrying work area. On the side of the first carrier guide rail 43 far from the carrying mechanism 5, a manipulator placement work area is formed so that the manipulator 2 can place the workpiece on the first carrier assembly 4; below the flipping bracket on the first carrier guide rail 43, a flipping acceptance area is formed so that the first carrier assembly 4 can move below the flipping mechanism 3 to accept the workpiece; on the side of the first carrier guide rail 43 close to the second carrier assembly 6, a handover and carrying work area is formed so that the carrying mechanism can carry the workpiece on the first carrier assembly 4.

[0084] The working range of the first carrier assembly 4 includes: when flipping is not required, the first carrier assembly 4 works in the manipulator placement work area, and the manipulator 2 can place the workpiece on the first carrier assembly 4; when flipping is required, the first carrier assembly 4 works in the flipping acceptance area, and the first carrier assembly 4 moves below the flipping mechanism 3 to accept the workpiece. Whether flipping is required or not, the first carrier assembly 4 can work in the handover and carrying work area, and the first carrier assembly 4 can carry the workpiece to below the carrying mechanism. The first carrier guide rail 43 is arranged between the flipping mechanism and the carrying guide rail, and the length of the first carrier guide rail 43 is long enough to meet the workpiece exchange and placement work with the manipulator, the workpiece flipping and acceptance work with the flipping mechanism, and the workpiece handover and carrying work with the carrying mechanism. At the same time, for reasonable layout and convenient work, looking along the length direction of the first carrier guide rail 43, the flipping mechanism 3 is located between the manipulator 2 and the carrying mechanism 5.

[0085] (6) The second carrier assembly

[0086] The second carrier assembly is used to fix the workpiece for laser drilling processing.

[0087] The second carrier assembly 6 is located on one side close to the handling guide rail. The second carrier assembly 6 is used to adsorb and fix the workpiece so that the laser device can perform a punching operation on the workpiece. The second carrier assembly 6 includes a second carrier, and a plurality of adsorption holes and waste holes are provided on the second carrier. The plurality of adsorption holes are used to adsorb and fix the workpiece; after the laser punching operation is performed on the workpiece, the punching waste falls into the waste holes. There are multiple second carriers. In the figure, the number of second carriers is two, and the two second carriers are installed through a carrier mounting member. The handling mechanism 5 transfers the workpiece from the first carrier assembly 4 to the second carrier assembly 6. Specifically, the handling mechanism 5 transports the workpiece from the first carrier assembly 4 to the two second carriers of the second carrier assembly 6. The second carrier assembly can perform XYθ movement adjustment to adjust the position of the workpiece on the second carrier assembly 6.

[0088] (7) Detection mechanism

[0089] The detection mechanism 7 is arranged in the transfer handling work area where the handling mechanism and the first carrier assembly hand over work.

[0090] One camera is provided on each side of the detection mechanism 7. The camera can move and capture an image of the workpiece on the first carrier assembly 4, and send the image to the control unit for analysis and processing to obtain the position of the workpiece on the first carrier assembly 4. The handling mechanism 5 accurately moves above the first carrier assembly 4 according to the position of the workpiece on the first carrier assembly 4, and transfers the workpiece from the first carrier assembly 4 to the second carrier assembly 6.

[0091] It should be noted that the loading mechanism 1, the manipulator 2, the flipping mechanism 3, the first carrier assembly 4, the handling mechanism 5, and the second carrier assembly 6 of the loading device can operate on two workpieces simultaneously to realize subsequent punching operations on the two workpieces.

[0092] The present invention also provides a loading method, using the loading device described above. The method includes the following steps:

[0093] Step S10: A number of full Tray trays filled with workpieces move to the first Tray tray placement area of the loading mechanism, and the manipulator sucks the workpieces on one full Tray tray filled with workpieces.

[0094] Specifically, step S10 includes the following steps:

[0095] Step S101: The first Tray tray moving channel of the loading mechanism is used to move a number of Tray trays filled with workpieces to the first Tray tray placement area of the loading mechanism.

[0096] Step S102: The first lifting component of the loading mechanism moves up and down to lift several full Tray trays filled with workpieces to the working range of the manipulator, and the manipulator picks up the workpieces on one full Tray tray.

[0097] Step S20: Detect and determine whether the workpiece needs to be flipped. If so, go to Step S30; if not, go to Step S40.

[0098] Step S30: The manipulator places the workpiece on the flipping mechanism, and the flipping mechanism flips the workpiece and places the workpiece on the first carrier component.

[0099] Specifically, Step S30 includes the following steps:

[0100] Step S301: The flipping mechanism rises to a suitable height position or remains stationary by itself, and the manipulator places the workpiece on the flipping mechanism to receive the workpiece and adsorbs and fixes the workpiece. Specifically, the manipulator places the workpiece on multiple mounting parts of the flipping mechanism to receive the workpiece and adsorbs and fixes the workpiece.

[0101] Step S302: The flipping mechanism flips the workpiece by 180 degrees.

[0102] Step S303: After the flipping is completed, the flipping mechanism descends to a height position matching the first carrier component and places the workpiece on the first carrier component.

[0103] Step S40: The manipulator places the picked-up workpiece on the first carrier component.

[0104] After Step S10, there is also Step ST, and Step ST includes the following steps:

[0105] Step ST01: One full Tray tray filled with workpieces becomes an empty Tray tray. The first group of suction cup components of the loading mechanism moves up and down to adsorb an empty Tray tray, the Tray tray transfer part of the loading mechanism moves to the lower part of an empty Tray tray, and the first group of suction cup components place an empty Tray tray on the Tray tray transfer part.

[0106] Step ST02: The Tray tray transfer part transfers the empty Tray tray from below the first group of suction cup components to below the second group of suction cup components, and the second group of suction cup components adsorb an empty Tray tray.

[0107] Step ST03: The Tray tray transfer part leaves from below the second group of suction cup components, and the second group of suction cup components place an empty Tray tray on the second carrier or on the already placed empty Tray tray.

[0110] After step S50, there is also included step S60: The second carrier assembly receives the workpiece and adsorbs and fixes it, and the laser device performs drilling on the workpiece.

[0111] Step ST can be synchronized with at least one of step S20, step S30, step S40, step S50, and step S60. It corresponds to the actual production process. Feeding, drilling, and discharging are preferably simultaneous, which can improve the working efficiency of the equipment.

[0112] After all the full Tray trays filled with workpieces are loaded, after step ST, there is also included step SE: The second Tray tray moving channel moves a number of stacked empty Tray trays outside the loading mechanism and removes the number of stacked empty Tray trays, realizing the discharging of the number of stacked empty Tray trays. Therefore, the loading mechanism provides the function of discharging empty Tray trays.
