[0014] The beneficial effects of the present invention compared to the prior art are:

[0015] The equipment of the present invention integrates the functions of batch loading, flipping, positioning, stress detection, automatic batch classification and unloading, and the various parts are integrated and coordinated to work together. It can automatically identify the QR code of the glass product, classify and detect whether the stress is qualified, and unload. Combined with the loading device and the unloading device, it can perform large-scale loading and unloading operations at one time, so that one machine can efficiently meet the entire inspection process of batch glass products, greatly reduce the cost of equipment procurement for production enterprises, and at the same time reduce the company's demand for manpower, meeting the batch operation needs of the assembly line.

[0016] The equipment of the present invention has a flipping mechanism, which is more adaptable to the state of the product. For glass products with curved edges, if the product is directly transferred to the detection position of the stress detection mechanism in the state of being placed in the material tray during stress detection, there may be problems such as poor fitting, which in turn affects the accuracy of the detection results. The setting of a loading flipping mechanism allows the product to be tested to be tested in the optimal position state. At the same time, a unloading flipping mechanism is set to receive the unloading. The flipping mechanism can be adaptively started or selectively started according to the product to be tested, thereby improving the adaptability of the overall equipment.

[0017] The equipment of the present invention has a positioning and scanning mechanism, a loading and temporary storage mechanism, and a unloading and temporary storage mechanism. The positioning and scanning mechanism is provided with a scanning device and a positioning platform. The positioning platform is provided with a fixed positioning column and a movable positioning column, so as to adapt to products of various sizes. Under the action of the fixed positioning column and the movable positioning column, it is ensured that the scanning device below can accurately scan the QR code on the product, so that the equipment can record data and trace the source of each product; products that have successfully scanned the code are transferred to the loading and temporary storage mechanism, and products that have completed the inspection are transferred to the unloading and temporary storage mechanism. The loading and temporary storage mechanism and the unloading and temporary storage mechanism both include a fixed temporary storage platform and a movable temporary storage platform, which carry the products to circulate in multiple stations of the inspection mechanism and serve as an intermediate buffer bridge to make the overall operation process smoother.

[0018] The equipment of the present invention is provided with an intermediate switching mechanism and is designed with two platforms that can be converted to carry products. The translation switching platform moves horizontally on the working plane, and the lifting switching platform can both translate and lift. Through switching, the two platforms are made to move back and forth between the unloading temporary storage mechanism and the unloading module, thereby realizing uninterrupted unloading of batch products, shortening the unloading time and improving efficiency.

[0019] The equipment of the present invention is provided with a batch loading and unloading mechanism. By arranging a tray bracket and a tray lifting mechanism in both the loading module and the unloading module, there is no need to operate a single tray when loading and unloading the tray. Multiple trays can be carried at one time. The loading and unloading manipulator is equipped with a multi-station clamp to meet the needs of large-scale rapid detection and greatly improve the overall loading and unloading efficiency.

[0020] The equipment of the present invention is equipped with a liquid suction mechanism, a non-conforming product storage mechanism, etc. The liquid suction mechanism can clean the refractive liquid remaining on the product before unloading, collect it and then centrally process it, thereby improving the cleanliness of the product when unloading. A non-conforming product storage mechanism is set at the product handling mechanism. When a product that fails the code scanning is detected, it is first transferred to the non-conforming product storage mechanism without affecting the progress of the overall inspection process. After the material transport robot completes the transfer of the products that pass the code scanning, the products in the non-conforming product storage mechanism are uniformly unloaded to the corresponding production line, thereby improving the overall inspection and unloading efficiency.

[0039] Reference Figure 1-Figure 3 , a batch glass stress detection automatic assembly line equipment of this embodiment includes a machine platform, a loading module, a stress detection module and a unloading module, wherein the stress detection module includes a turning mechanism 2, a positioning and scanning mechanism 3, a loading temporary storage mechanism 4, a stress detection mechanism 5, a unloading temporary storage mechanism 6, a unloading transfer mechanism 7 and a product conveying mechanism 8 arranged on the machine platform, the turning mechanism 2 includes a loading turning mechanism 2a and a unloading turning mechanism 2b, the loading module 1, the loading turning mechanism 2a, the positioning and scanning mechanism 3, the loading temporary storage mechanism 4, the stress detection mechanism 5, the unloading temporary storage mechanism 6, the unloading transfer mechanism 7 and the unloading module 9 are arranged sequentially from the loading direction to the unloading direction, and the product conveying mechanism 8 is set on both sides of the stress detection mechanism 5.

[0040] The loading module 1 comprises a tray-carrying conveyor platform 11 and a loading mechanism 12 mounted on the machine platform 100. The loading mechanism 12 grips and transfers the product 200 to be inspected to the loading and flipping mechanism 2a and the positioning and scanning mechanism 3. The product transport mechanism 8 comprises a first product transport mechanism 8a and a second product transport mechanism 8b arranged in parallel. Two or more stress detection mechanisms 5 are installed in two rows on the machine platform 100, with one or more stress detectors in each row to further improve inspection speed. The first product transport mechanism 8a and the second product transport mechanism 8b are respectively installed on one side of each row of stress detection mechanisms 5, and are used to transport and transfer products 200 between the loading temporary storage mechanism 4, the stress detection mechanism 5, the unloading temporary storage mechanism 6 and the unloading transfer mechanism 7. The unloading module 9 includes a unloading movement mechanism 91 and multiple discharge flow channels 92. The unloading movement mechanism 91 classifies the products 200 transported from the unloading transfer mechanism 7 and places them on the corresponding discharge flow channels.

[0041] Specifically, refer to Figure 3-Figure 5The first and second product transport mechanisms 8a, 8b are mounted above the stress detection mechanism 5 via a crossbeam support 81. Each mechanism includes a first linear motor 82, multiple first slides 83 mounted on the first linear motor 82, multiple material transport robots, a failed code scanning storage table 85, and a liquid aspiration mechanism 86. The first linear motor 82 is mounted on the crossbeam of the crossbeam support 81. Each material transport robot is movably mounted on each first slide 83 via a first lifting module 87. Each first slide 83 independently moves laterally under the drive of the first linear motor 82, and each material transport robot independently moves vertically under the drive of the first lifting module 87. The multiple transport manipulators on the first product transport mechanism 8a include a first transport manipulator 841, a second transport manipulator 842, and a third transport manipulator 843. The multiple transport manipulators on the second product transport mechanism 8b include a fourth transport manipulator 844 and a fifth transport manipulator 845. The transport manipulators are preferably rotatable cylinder grippers. The fourth and fifth transport manipulators 844, 845, and the first and second transport manipulators 841, 842 share the same structure: a single cylinder gripper on the first lifting module 87, while the third transport manipulator 843 has at least two parallel cylinder grippers on the first lifting module 87. The first material transport robot 841 and the fourth material transport robot 844 are used to transfer the products on the loading temporary storage mechanism 4 to the stress detection mechanism 5 or the scanned unqualified storage table 85. The second material transport robot 842 and the fifth material transport robot 845 are used to transfer the products on the stress detection mechanism 5 to the unloading temporary storage mechanism 6. At the same time, the products on the scanned unqualified storage table 85 are also transported to the unloading temporary storage mechanism 6 by the second material transport robot 842 and / or the fifth material transport robot 845. The third material transport robot 843 is used to transfer the products on the unloading temporary storage mechanism 6 to the unloading transfer mechanism 7.

[0042] Among them, the liquid suction mechanism 86 includes an adsorption bracket 861, an adsorption plate 862, and a liquid bottle. The adsorption bracket 861 is arranged on the beam bracket 81 of the product transport mechanism, the adsorption plate 862 is arranged on the adsorption bracket 861, and the liquid bottle is connected to the bottom of the adsorption plate 862. Because the product 200 needs to be dripped with liquid oil, such as refractive liquid, during stress testing to assist in detection, in order to collect and transfer the subsequent product 200 cleanly, the second material transport robot 842 and the fifth material transport robot 845 will clamp the products that have completed the inspection on their operating lines to the adsorption plate 862, and then the vacuum pump connected to the adsorption plate 862 will be started to provide suction force to adsorb the liquid on the surface of the product placed on the adsorption plate 862 into the liquid bottle for collection for centralized processing. At the same time, non-woven fabric is laid on the adsorption plate 862 to further improve the cleaning efficiency of the refractive liquid.

[0043] Reference Figure 6 The positioning and scanning mechanism 3 includes a positioning platform 31, a scanning camera 32, a fixed positioning column 33 and a movable positioning column 34. At least two positioning stations are set on the positioning platform 31, and a scanning window is opened on each positioning station. The fixed positioning column 33 is fixedly arranged on the outer periphery of the adjacent vertical sides of the scanning window. Sliding grooves 35 are opened on the two sides of the positioning platform 31 opposite to the fixed positioning column 33. The movable positioning column 34 is movably arranged in the sliding groove 35. The driving mechanism set below the positioning platform 31 drives the movable positioning column 34 to move closer to or away from the fixed positioning column 33 in the sliding groove 35. The driving mechanism can be a driving cylinder or a servo motor. The product is placed on the positioning station, and the movable positioning column 34 moves to push the product flat against the fixed positioning column 33, thereby cooperating with the fixed positioning column 33 to complete the fixed positioning of the product 200, so that the scanning camera 32 below can accurately scan the QR code of the product. A barcode scanning camera 32 is mounted on the machine platform, below the scanning window of the positioning platform 31. It scans the QR codes of products displayed on the positioning platform 31 above, enabling the equipment to record and trace each product's data. Successfully scanned products are gripped and transferred by the loading mechanism 12 to the loading temporary storage mechanism 4. The first and fourth transport robots 841 and 844 then transfer them to the stress detection mechanism 5 for stress testing. Unsuccessful products are directly moved by the first and fourth transport robots 841 and 844 to the failed storage table 85. The second and fifth transport robots 842 and 845 then transfer them to the unloading temporary storage mechanism 6. The third transport robot 843 then transfers the products from the unloading temporary storage mechanism 6 to the unloading transfer mechanism 7. The unloading mechanism 91 then sorts the products in the unloading transfer mechanism 7 into their corresponding categories, ready for discharge from the equipment.

[0044] Reference Figure 7The loading temporary storage mechanism 4 and the unloading temporary storage mechanism 6 have the same structure, but are located in different positions. The loading temporary storage mechanism 4 is close to the loading end and is located between the positioning and scanning mechanism 3 and the stress detection mechanism 5. The unloading temporary storage mechanism 6 is close to the unloading end and is located between the stress detection mechanism 5 and the unloading transfer mechanism 7. The loading temporary storage mechanism 4 and the unloading temporary storage mechanism 6 both include a fixed temporary storage table 41 fixedly set on the machine 100, a moving mechanism 42 and a movable temporary storage table 43 set on the moving mechanism 42. The moving mechanism 42 and the fixed temporary storage table 41 are arranged in the same straight line direction perpendicular to the product conveying mechanism 8. The fixed temporary storage table 41 is arranged on one side of the first product conveying mechanism 8a. The movable temporary storage table 43 moves towards or away from the second product conveying mechanism 8b under the drive of the moving mechanism 42. Specifically, the moving mechanism 42 includes a linear module 421 and a guide rail 422. The movable temporary storage table 43 is supported by a base 423 and a support column 424. It is installed on the slide of the linear module 421 and driven by the linear module 421 to perform linear motion on the guide rail 422.

[0045] At the loading end, the movable temporary storage table 43 of the loading temporary storage mechanism 4 moves to a position close to the fixed temporary storage table 41, and the loading motion mechanism transfers the two products on the double positioning station of the positioning platform 31 to the fixed temporary storage table 41 and the movable temporary storage table 43. Then the movable temporary storage table 43 is driven by the moving mechanism 42 to the second product transporting mechanism 8b, and the fourth material transporting robot 844 clamps the products on it and transports them to the inspection position of the stress detection mechanism 5 for inspection, or the fourth material transporting robot 844 clamps and transports the products that fail the code scanning to the unqualified code scanning storage table 85. The first material transporting robot 841 clamps and transports the products that pass the code scanning and the products that fail the code scanning on the fixed temporary storage table 41 to the inspection position of the stress detection mechanism 5 and the unqualified code scanning storage table 85 respectively. At the unloading end, the fifth material transport robot 845 clamps and transfers the products that have completed inspection on the stress detection mechanism 5, or the products on the unqualified storage table 85 that have been scanned to the movable temporary storage table 43 in the unloading temporary storage mechanism 6. The movable temporary storage table 43 in the unloading temporary storage mechanism 6 is driven by the moving mechanism 42 to the first product handling mechanism 8a, and then the third material transport robot 843 transfers the products on the movable temporary storage table 43 and the fixed temporary storage table 41 to the unloading transfer mechanism 7.

[0046] refer to Figure 8The loading and turning mechanism 2a is used to turn the product over during loading, and includes a loading and turning robot 21 and a turning platform 22. The turning platform 22 is mounted on the machine 100. The turning platform 22 is provided with at least two placement stations. The loading and turning robot 21 is arranged on both sides of the turning platform 22 through a bracket 23. The loading and turning robot 21 includes a first lifting motor 211 and a first rotary electric gripper 212. The first rotary electric gripper 212 is arranged on the first lifting motor 211 and is driven by the first lifting motor 211 to perform lifting movement to avoid the loading movement mechanism 12. The first lifting motor 211 is arranged on the bracket 23. The first rotary electric gripper 212 is used to clamp the product on the turning platform 22 for clamping and turning it over.

[0047] Combined with reference Figure 11 There are two blanking and flipping mechanisms 2b, which are used to flip the product when unloading. One is set at the first product conveying mechanism 8a and the second product conveying mechanism 8b respectively. The blanking and flipping mechanism 2b includes a second lifting motor 24 and a second rotary electric gripper 25. The second rotary electric gripper 25 is set on the second lifting motor 24 and driven by the second lifting motor 24 to perform lifting and lowering movements. The second lifting motor 24 is fixed to the machine table through a support column. The second rotary electric gripper 25 is used to clamp the product 200 for flipping. The blanking and flipping mechanism 2b and the blanking temporary storage mechanism 6 are located on the same straight line. Specifically, the unloading and flipping mechanism 2b is located on the same straight line as the fixed temporary storage table 41 and the movable temporary storage table 43 in the unloading and temporary storage mechanism 6. The second rotating electric gripper 25 provided at the first product handling mechanism 8a is used to clamp the products on the fixed temporary storage table 41 in the flipping unloading and temporary storage mechanism 6. The second rotating electric gripper 25 provided at the second product handling mechanism 8b is used to clamp the products on the movable temporary storage table 43 in the flipping unloading and temporary storage mechanism 6. The function of the second lifting motor 24 is to drive the second rotating electric gripper 25 to rise and fall so as to avoid the material transport robot from transporting the products to the movable temporary storage table 43 and the fixed temporary storage table 41.

[0048] In addition, refer to Figure 9The unloading transfer mechanism 7 includes a transfer frame 71, a translational transfer platform 72, a lifting transfer platform 73, a synchronous belt 74, a motion drive mechanism 75, and a lifting guide platform 76 mounted on the transfer frame 71. Each translational transfer platform 72 and the lifting transfer platform 73 are equipped with at least two product positions 77, each surrounded by multiple positioning mechanisms comprising adjustable positioning pins 771. The third material transport robot 843 synchronously transfers products from the unloading temporary storage mechanism 6 to the two product positions 77 on the translational transfer platform 72 or the lifting transfer platform 73. The translational transfer platform 72 and the lifting transfer platform 73 then change positions, transferring the products to the unloading module 9. The unloading motion mechanism 91 then sorts the products in the unloading transfer mechanism 7 and transfers them to the corresponding discharge channel 92 for discharge from the equipment. The synchronous belt 74 is set on the two opposite inner walls of the transfer frame 71 through the synchronous pulley. The translation transposition platform 72 is movably set on the transfer frame 71 through the slide rail 721. The motion drive mechanism 75 is connected to the translation transposition platform 72 to drive the translation transposition platform 72 to move on the slide rail 721. The translation transposition platform 72 and the lifting transposition platform 73 are both connected to the synchronous belt 74. When the translation transposition platform 72 moves on the slide rail 721, it synchronously drives the lifting transposition platform 73 to move in the opposite direction of the translation transposition platform 72. The lifting guide platform 76 is arranged inside the transfer frame 71. A stepped moving groove 761 is provided on the lifting guide platform 76. The lifting and transposition platform 73 is connected to the moving groove 761 through a connecting rod 731. One end of the connecting rod 731 is fixed to the bottom of the lifting and transposition platform 73, and the other end of the connecting rod 731 is movably arranged in the moving groove 761 through a guide wheel 732. When the synchronous belt 74 drives the lifting and transposition platform 73 to move, the connecting rod 731 performs a smooth lifting and lowering motion in the moving groove 761, thereby driving the lifting and transposition platform 73 to lift and lower while moving horizontally, and staggered with the translation of the translation transposition platform 72 to avoid collision.

[0049] Further references Figure 10The movable channel 761 includes two sections of horizontal upper channels 7611, two sections of inclined channels 7612 and one section of horizontal lower channel 7613. The vertical distance between the upper channel 7611 and the plane where the translation transposition platform 72 is located is smaller than the vertical distance between the lower channel 7613 and the plane where the translation transposition platform 72 is located. The two ends of the inclined channel 7612 are respectively connected to the upper channel 7611 and the lower channel 7613. When the guide wheel is in the upper channel 7611, the connecting rod 731 supports the lifting and transposition platform 73 and the translation transposition platform 72 at the same horizontal height. When the guide wheel 732 moves along the inclined channel 7612 to the lower channel 7613, the lifting and transposition platform 73 is lower than the translation transposition platform 72. In the process of the motion drive mechanism 75 synchronously driving the two to move, the lifting and transposition platform 73 and the translation transposition platform 72 are staggered and exchanged. The transfer frame 71 also includes a balancing guide mechanism 78, which includes a guide post 781 and a guide plate 782. A connecting rod 731 extends through the center of the guide plate 782 and connects to the movable channel 761 below. The guide posts 781 are located at the four corners of the guide plate 782, providing stable guidance for the lifting and repositioning platform 73 during its movement. The motion drive mechanism 75 can optionally be a rodless cylinder. The motion drive mechanism 75 is located on the outside of the transfer frame 71, with synchronous pulleys located at both ends of the inside of the transfer frame 71. A synchronous belt 74 is mounted on the synchronous pulleys and meshes with the gears matching the synchronous pulleys. One end of the translational repositioning platform 72 is clamped to the synchronous belt 74 by a clamping plate, while the other end is attached to the movable end of the rodless cylinder via a connecting seat 722. One end of the guide plate 782 is fixed to the synchronous belt 74 by a clamp. The clamp on the guide plate 782 and the clamp on the translation transposition platform 72 are respectively arranged on the upper and lower sides of the synchronous belt 74, so that when the synchronous belt 74 is driven, the translation transposition platform 72 and the lifting transposition platform 73 move in opposite directions. Due to the high and low structure setting of the upper groove 7611 and the lower groove 7613 of the moving groove 761, the translation transposition platform 72 and the lifting transposition platform 73 will not collide during the position change process, including no scratching when the translation transposition platform 72 and the lifting transposition platform 73 carry tooling and / or products, thereby achieving complete dislocation movement and conversion of positions, thereby achieving high-speed and uninterrupted material unloading.

The empty product tray on the loading tray is transferred to the empty tray loading station 500. A movable positioning block 410 and a fixed positioning block 420 are respectively provided on both sides of the loading and unloading station 400 to further accurately position the product tray 600 transferred from the full tray loading station 300, ensuring that the loading motion mechanism 12 accurately clamps the products on the product tray 600. In addition, at least two loading positions 430 are provided on the side close to the fixed positioning block 420. The loading motion mechanism 12 is erected across the loading and retrieving station 400. The loading motion mechanism 12 includes a second linear motor 121, a plurality of second slides 122 arranged on the second linear motor 121, a first loading robot 123 and a second loading robot 124. The first loading robot 123 and the second loading robot 124 are respectively arranged on different second slides 122 through a second lifting module 125. At least two rotating claws 126 are arranged side by side in the first loading robot 123, and two rows of rotating claws 126 are arranged side by side in the second loading robot 124, each row including at least two rotating claws 126. In this embodiment, at least four rotating claws 126 are arranged in a matrix in the second loading robot 124, two in a row, and the row close to the side of the first loading robot 123 will be the loading position 430 The products on the flipping platform 22 of the feeding and turning mechanism 2a are clamped and transferred. Synchronously, the row away from the first feeding robot 123 transfers the products on the flipping platform 22 that have been turned over to the positioning platform 31 of the positioning and scanning mechanism 3. On this basis, the row close to the first feeding robot 123 transfers the products on the flipping platform 22 to the positioning platform 31. Correspondingly, the row away from the first feeding robot 123 transfers the products on the positioning platform 31 to the fixed temporary storage table 41 and the movable temporary storage table 43 of the feeding temporary storage mechanism 4. By analogy, the second feeding robot 124 transfers products in pairs between the four operating stations synchronously.

[0051] In addition, combined with reference Figure 14 、 Figure 15 , a loading tray bracket 111 and a loading tray lifting mechanism are provided at the loading full tray station 300 and the loading empty tray station 500 on the tray carrying and conveying platform 11. The loading tray bracket 111 is used to support the stacked product trays 600. The loading tray bracket 111 includes an end angle limit plate 1111, a base 1112, and a limit cylinder 1113. The base 1112 is set on the limit cylinder 1113 and is driven by the limit cylinder 1113 to move closer to or away from the product tray 600. The end angle limit plate 1111 is detachably set at both ends of the base 1112 and is stuck on the end corners of the product tray 600 to fix its position. The detachable setting can replace the appropriate end angle limit plate 1111 according to the size of the product tray 600. The base 1112 faces the product tray 600. A support ear 1114 is provided in the direction of the product tray 600, which is used to hold the product tray 600. The loading tray lifting mechanism is movably arranged below the product tray 600 and includes a lifting cylinder 1121 and a suction platform 1122. The suction platform 1122 is located at the piston end of the lifting cylinder 1121. The lifting cylinder 1121 drives the suction platform 1122 close to the product tray 600 above, and then sucks and drives the product tray 600 that has escaped the restraint of the support ear 1114 down to the synchronous conveyor belt mechanism for transportation to other workstations.

[0052] At the full tray loading station 300, multiple product trays 600 filled with products to be inspected are stacked in the loading tray bracket 111. The base 1112 drives the end corner limit plates 1111 to be stuck at the four end corners of the product tray 600 under the action of the limit cylinder 1113, and the support ears 1114 are stuck in the bottom of the side of the lowest product tray, thereby supporting all the product trays 600. When loading begins, the lifting cylinder 1121 below the product tray 600 starts to drive the adsorption platform 1122 to the bottom of the product tray 600. The limit cylinder 1113 starts to drive the base 1112 and the support ears 1114 away from the lowest product tray, releasing the restriction on them. The adsorption platform 1122 is adsorbed on the bottom of the product tray 600 and drives it to descend. The limit cylinder 1113 starts again to drive the base 1112 and the support ears 1114 to move upward. 600 and then the loading tray 600 is lifted up by the loading tray lifting mechanism at the empty loading tray station 500. As the empty product trays 600 are successively delivered to the empty tray loading station 500, the loading tray lifting mechanism and the loading tray bracket 111 lift and fix the empty product trays 600 one by one, so as to centrally process the empty product trays 600 without affecting the overall process.

[0053] Reference Figure 16 The unloading motion mechanism 91 in the unloading module 9 includes a third linear motor 911, a third slide 912 arranged on the third linear motor 911, and an unloading robot 913. The unloading robot 913 is set on the third slide 912 through the third lifting module. The unloading robot 913 has the same structure as the first loading robot 123, wherein at least two rotating clamps are arranged side by side, and the specific number corresponds to the number of product carriers 77 of the unloading transfer mechanism 7.

[0054] Three discharge water channels 92 are set in the unloading module 9, namely the qualified product channel 92a, the unqualified product channel 92b and the scan code unqualified channel 92c. Each discharge water channel 92 is divided into a full material tray unloading station 700, a material unloading station 800 and an empty material tray unloading station 900. Each discharge water channel 92 is provided with a synchronous transmission belt mechanism, an unloading tray bracket 921 and an unloading tray lifting mechanism. The unloading tray bracket 921 has the same structure as the loading tray bracket 111 in the loading module 1, and the unloading tray lifting mechanism has the same structure as the loading tray lifting mechanism. The specific structure of the unloading tray bracket 921 can be referred to. Figure 14 The specific structure of the loading tray bracket 111 and the unloading tray lifting mechanism can be referred to Figure 15 The loading tray lifting mechanism, the unloading tray bracket 921 and the unloading tray lifting mechanism work in conjunction with the loading tray bracket 111 and the loading tray lifting mechanism.

[0055] The workflow of the unloading module 9 is opposite to that of the loading module 1. In the unloading module 9, the empty product trays 600 stacked on the empty unloading tray station 900 are lowered one by one onto the synchronous conveyor belt mechanism with the cooperation of the unloading tray lifting mechanism and the unloading tray bracket 921, and are transported to the unloading and discharge station 800 by the synchronous conveyor belt mechanism. The unloading robot 913 clamps the products in the translation exchange platform 72 and the lifting exchange platform 73 and transports them to the product tray 600 to fill them up. The synchronous conveyor belt mechanism then continues to drive the full product tray to the unloading full tray station 700. The unloading tray lifting mechanism and the unloading tray bracket 921 at the full tray station 700 lift the filled product trays 600 one by one and stack them and fix them. At the same time, when the unloading robot 913 clamps and transports the products in the translation exchange platform 72 and the lifting exchange platform 73 to the product tray 600 of the unloading and discharge station 800, the unloading robot 913 will move to the corresponding discharge flow channel 92 according to the scanning and detection results of the clamped products, thereby realizing the classification and collection of the products.

[0056] In addition, in this application, the clamps and / or grippers involved in clamping and transporting products are preferably made of PEEK material, and multiple elastic pads are provided on the inner side of the clamps that contact the product, using an elastic line contact method to ensure the clamping safety of the product while reducing the contact area. The elastic pads are preferably rubber strips.

[0057] Equipment workflow:

[0058] Loading: In the loading module, the operator stacks multiple product trays 600 loaded with products on the loading full tray station 300 of the tray carrying and conveying platform 11. The loading tray bracket 111 and the loading tray lifting mechanism work together to support the product trays 600 and bring them down one by one, and land on the synchronous transmission belt mechanism. The synchronous transmission belt mechanism transports the product trays 600 to the loading and unloading station 400 to be picked up by the first loading robot 123. The rotating claws 126 of the first loading robot 123 clamp the products in the product tray 600 and transfer them to the waiting loading position 430. One row of rotating claws 126 in the second loading robot 124 clamps the products at the waiting loading position 430 and transfers them to the flipping platform 22 of the loading flipping mechanism 2a. The first rotary electric gripper 212 flips the products, and synchronously, another row of rotating claws 126 flips the flipping platform 22 The products that have been turned over are clamped and transferred to the positioning platform 31 of the positioning and code scanning mechanism 3. On this basis, the second loading robot 124 further translates in the same direction, and one row of rotating claws 126 clamps the products on the flipping platform 22 and transfers them to the positioning platform 31. Another row of rotating claws 126 clamps the products that have completed positioning and code scanning on the positioning platform 31 and transfers them to the fixed temporary storage table 41 and the movable temporary storage table 43 of the loading temporary storage mechanism 4. And so on, the second loading robot 124 transfers products synchronously between the four operating stations in pairs. The emptied product tray 600 is then driven by the synchronous conveyor belt mechanism to be transferred to the empty tray loading station 500. In contrast to the action of lowering the product trays 600 one by one at the full tray loading station 300, the loading tray lifting mechanism at the empty tray loading station 500 lifts up the empty product tray 600, and then the loading tray bracket 111 here supports and fixes the product tray 600. As the empty product trays 600 are successively transferred to the empty tray loading station 500, the loading tray lifting mechanism and the loading tray bracket 111 lift and fix the empty product trays 600 one by one and stack them.

[0059] Inspection: After being turned over by the loading and turning mechanism 2a and scanned by the positioning and scanning mechanism 3, the products are transferred to the fixed temporary storage table 41 and the movable temporary storage table 43 of the loading and temporary storage mechanism 4. The movable temporary storage table 43 is then driven by the moving mechanism 42 to the second product transporting mechanism 8b, and the fourth material transporting robot 844 clamps the products on it and transports them to the inspection position of the stress detection mechanism 5 for inspection, or the fourth material transporting robot 844 clamps and transports the products that fail the code scanning to the unqualified code scanning storage table 85. The first material transporting robot 841 clamps and transports the products that pass the code scanning on the fixed temporary storage table 41 to the inspection position of the stress detection mechanism 5 for inspection, or transports the products that fail the code scanning to the unqualified code scanning storage table 85 for storage. The products that have completed stress testing are clamped by the second material transport robot 842 and the fifth material transport robot 845 to the adsorption disk 862 of the liquid suction mechanism 86 to absorb the cleaning refractive liquid, and then transferred to the fixed temporary storage table 41 and the movable temporary storage table 43 in the material unloading temporary storage mechanism 6. The products on the movable temporary storage table 43 are clamped and turned over by the second rotary electric gripper 25 in the material unloading flipping mechanism 2b and then transferred to the fixed temporary storage table 41. At the same time, the products on the fixed temporary storage table 41 are also turned over. After turning over, the third material transport robot 843 transports the products to the two product loading positions 77 on the translation exchange platform 72 or the lifting exchange platform 73. The translation exchange platform 72 and the lifting exchange platform 73 change their positions and transfer the products to the unloading module 9. The unloading motion mechanism 91 then transfers the products to the unloading transfer mechanism 7 The products are classified into the corresponding categories and transferred to the discharge water channel 92 to be discharged from the equipment.

[0060] Unloading: Unloading robot 913 moves to the corresponding discharge flow channel 92 according to the scan code and detection results of the clamped product, so as to realize the classification of the products. In each discharge flow channel 92, the empty product trays 600 stacked in advance by the staff on the unloading empty tray station 900 are lowered one by one onto the synchronous transmission belt mechanism under the cooperation of the unloading tray lifting mechanism and the unloading tray bracket 921, and are transported to the unloading and unloading station 800 by the synchronous transmission belt mechanism. The unloading robot 913 clamps the products in the translation exchange platform 72 and the lifting exchange platform 73 and moves them to the product tray 600 to fill them. Then the synchronous transmission belt mechanism continues to drive the full product tray to move to the unloading full tray station 700. The unloading tray lifting mechanism and the unloading tray bracket 921 at the unloading full tray station 700 cooperate to lift the filled product tray 600. They are lifted up and stacked one by one. When the product trays on the unloading tray station 700 are full, the operator can remove multiple trays of materials at the same time.
